This article assesses the legal character and operational relevance of the Paris Agreement's 1.5°C temperature goal. This article begins with a textual analysis of the 1.5°C goal. It considers whether the goal creates individual or collective obligations for Parties, and whether it is sufficiently specific to enable the tracking of individual or collective performance. Next, it assesses the operational relevance of the 1.5°C temperature goal, by considering the role it will play in the Paris Agreement's institutions and procedures. To the extent that the goal plays a role, and implies global limits on greenhouse gas emissions, this article observes that it could have implications for the sharing of the effort between Parties. Thus, this article considers the relevance of equity and the principle of common but differentiated responsibilities and respective capabilities, in the light of different national circumstances, to understanding how the 1.5°C goal could be reached. In this context, this article explores whether the 1.5°C goal could play a role in the Paris Agreement's `ambition cycle'. Finally, this article asks whether there are any legal or political implications, individually or collectively under the Paris Agreement, should the Parties fail to achieve the 1.5°C goal. This article is part of the theme issue `The Paris Agreement: understanding the physical and social challenges for a warming world of 1.5°C above pre-industrial levels'.

The Eiffel Tower and its shadow can be seen next to the Seine in the left middle of this ASTER image of Paris. Based on the length of the shadow and the solar elevation angle of 59 degrees, we can calculate its height as 324 meters (1,054 feet), compared to its actual height of 303 meters (985 feet). Acquired on July 23, 2000, this image covers an area 23 kilometers (15 miles) wide and 20 kilometers (13 miles) long in three bands of the reflected visible and infrared wavelength region. Known as the City of Light, Paris has been extolled for centuries as one of the great cities of the world. Its location on the Seine River, at a strategic crossroads of land and river routes, has been the key to its expansion since the Parisii tribe first settled here in the 3rd century B.C. http://photojournal.jpl.nasa.gov/catalog/PIA02660

Ice-free Arctic projections under the Paris Agreement

Sigmond, Michael; Fyfe, John C.; Swart, Neil C.

2018-05-01

Under the Paris Agreement, emissions scenarios are pursued that would stabilize the global mean temperature at 1.5-2.0 °C above pre-industrial levels, but current emission reduction policies are expected to limit warming by 2100 to approximately 3.0 °C. Whether such emissions scenarios would prevent a summer sea-ice-free Arctic is unknown. Here we employ stabilized warming simulations with an Earth System Model to obtain sea-ice projections under stabilized global warming, and correct biases in mean sea-ice coverage by constraining with observations. Although there is some sensitivity to details in the constraining method, the observationally constrained projections suggest that the benefits of going from 2.0 °C to 1.5 °C stabilized warming are substantial; an eightfold decrease in the frequency of ice-free conditions is expected, from once in every five to once in every forty years. Under 3.0 °C global mean warming, however, permanent summer ice-free conditions are likely, which emphasizes the need for nations to increase their commitments to the Paris Agreement.

Paris and its long-term temperature goal: First steps on a long road

As a means to achieve its long-term temperature goal, the Paris Agreement put in place a system of regularly updated country pledges alternating with global stocktaking exercises that assess progress towards achieving the Paris goals. By now, the vast majority of countries have submitted their intended actions (also known as Nationally Determined Contributions - NDCs). This begs the question what these amount to and whether they are in line with the agreement`s long-term temperature goal. A structured sensitivity analysis of the emissions implications of the Paris pledges has been carried out, showing that the ambiguity and imprecision of the NDCs leaves open a wide range of possible outcomes by 2030. This range has important implications for the feasibility and cost of pathways that attempt to limit warming to the temperature goals of the Agreement. We identify salient steps to reduce the overall uncertainty, and explore the minimum requirements that have to be met for integrated energy-economy-land models to still find options to stay within the temperature limits of the Paris Agreement. These requirements come under the form of near-term emissions reductions, and assumptions about the deployment of carbon-dioxide removal technologies in the second half of the century.

More attention was paid to the anti-tumor activity of Rhizoma Paridis (RP) recently, of which the wild resource was decreased significantly. This study was aimed to elucidate the chemical characteristics of Paris fargesii var. brevipetala (PFB) that may be administrated as alternate resource of legal RP. A HPLC-ELSD method was established to characterize the steroid saponins in rhizomes of PFB and two legal Paris species [Paris polyphylla var. chinensis (PPC) and P. polyphylla var. yunnanensis (PPY)] in Chinese Pharmacopoeia (CP). Ten saponins (paris saponins I, II, V, VI, VII, H, gracillin and other three paris saponins) were involved as standards. The results indicated that PFB contained pennogenyl saponins as the main components with small amounts of diosgenin saponins. The total contents of the detected saponins in PFB ranged from 9.12mg/g to 85.33mg/g. Nine of the twelve PFB samples own a total content of paris saponins I, II, VI, and VII more than 6.0mg/g (meeting the standard of CP 2010 edition). Principal Component Analysis (PCA) and Partial Least Squares-Discriminate Analysis (PLS-DA) both confirmed the fact that saponin profiles of PFB, PPC and PPY were different from each other. In addition, paris saponin H (Ps H), the predominant saponin of PFB (>50%), was tested in vitro to evaluate its cytotoxic activities on HepG2, A549, RPE and L929 cells with a positive control of Cisplatin. Ps H showed a remarkable cytotoxic activity on A549 cells with an IC(50) value of 1.53±0.08μg/mL. Copyright © 2012 Elsevier B.V. All rights reserved.

The contribution of Paris to limit global warming to 2 °C

DOE Office of Scientific and Technical Information (OSTI.GOV)

Iyer, Gokul C.; Edmonds, James A.; Fawcett, Allen A.

International negotiators have clearly articulated a goal to limit global warming to 2°C. In preparation for the 21st Conference of Parties (COP21) in Paris in December 2015, countries are submitting their Intended Nationally Determined Contributions (INDCs) to the United Nations Framework Convention on Climate Change indicating their emissions reduction commitments through 2025 or 2030. Limiting global warming to 2°C is a challenging goal and will entail a dramatic transformation of the global energy system, largely complete by 2040. The deliberations in Paris will help determine the balance of challenges faced in the near-term and long-term. We use GCAM, a globalmore » integrated assessment model, to analyze the energy and economic-cost implications of INDCs. The INDCs imply near-term actions that reduce the level of mitigation needed in the post-2030 period, particularly when compared with an alternative path, in which nations are unable to undertake emissions mitigation until after 2030. We find that the latter case could require up to 2300 GW of premature retirements of fossil fuel power plants and up to 2900 GW of additional low-carbon power capacity installations within a five-year period of 2031 to 2035. INDCs have the effect of reducing premature retirements and new-capacity installations after 2030 by 50% and 34% respectively. However, if presently announced INDCs were strengthened to achieve greater near-term emissions mitigation, the 2031-2035 transformation could be tempered to require 84% fewer premature retirements of power generation capacity and 56% fewer new-capacity additions. Our results suggest that the ensuing COP21 in Paris will be critical in shaping the challenges of limiting global warming to 2°C.« less

The Paris climate agreement aims at holding global warming to well below 2 degrees Celsius and to "pursue efforts" to limit it to 1.5 degrees Celsius. To accomplish this, countries have submitted Intended Nationally Determined Contributions (INDCs) outlining their post-2020 climate action. Here we assess the effect of current INDCs on reducing aggregate greenhouse gas emissions, its implications for achieving the temperature objective of the Paris climate agreement, and potential options for overachievement. The INDCs collectively lower greenhouse gas emissions compared to where current policies stand, but still imply a median warming of 2.6-3.1 degrees Celsius by 2100. More can be achieved, because the agreement stipulates that targets for reducing greenhouse gas emissions are strengthened over time, both in ambition and scope. Substantial enhancement or over-delivery on current INDCs by additional national, sub-national and non-state actions is required to maintain a reasonable chance of meeting the target of keeping warming well below 2 degrees Celsius.

The Paris Agreement culminates a six-year transition towards an international climate policy architecture based on parties submitting national pledges every five years. An important policy task will be to assess and compare these contributions. We use four integrated assessment models to produce metrics of Paris Agreement pledges, and show differentiated effort across countries: wealthier countries pledge to undertake greater emission reductions with higher costs. The pledges fall in the lower end of the distributions of the social cost of carbon and the cost-minimizing path to limiting warming to 2 °C, suggesting insufficient global ambition in light of leaders’ climate goals. Countries’ marginal abatement costs vary by two orders of magnitude, illustrating that large efficiency gains are available through joint mitigation efforts and/or carbon price coordination. Marginal costs rise almost proportionally with income, but full policy costs reveal more complex regional patterns due to terms of trade effects.

Innovative contributions and continued diplomacy will be necessary on the path forward from Paris

The historic Paris Agreement from the 21stUnited Nations Framework Convention on Climate Change (UNFCCC) Conference of the Parties (COP21) is scientifically based on the five Assessment Reports of the Intergovernmental Panel on Climate Change (IPCC), as well as 11 Special Reports on specific aspects on climate change and its management. But of equal importance has been the legacy of learning how to come to an agreement developed by trial and error over the past 20 COPs. A new feature, largely hailed as the key to success of COP21, was the decision to move away from `top down' specific binding requirements to a larger role for countries to determine their own commitments `bottom up'. These country pledges, known as Nationally Determined Contributions (NDCs), give nations the flexibility to determine which strategies to reduce greenhouse gases will work most effectively in their countries. An interesting consequence of this approach is that some strategies that had not previously been discussed in negotiations, like ocean carbon sequestration, have been incorporated into pledges that were made going into Paris and will likely be in the NDCs that countries declare as they formally join the Paris Agreement. While the concurrence of 180 entities as signatories to the Paris Agreement is an unprecedented international diplomatic achievement, there remains much to be done. By virtue of the voluntary nature of the NDCs, there is no assurance that the pledges will be sufficient to reach the goal of limiting temperature increases to 2°C, no less the more ambitious target of `well below 2°C' endorsed in the agreement. In fact, most assessments of the pledges suggest that in aggregate they will fall well short of the 2°C goal. In addition, there is no structure to assure compliance of countries with their NDCs - or even to comprehensively measure compliance or forecast likely future emission scenarios given exiting or emerging policies and technologies.

At the Pisgah Astronomical Research Institute (PARI) in Rosman, NC I spent 8 weeks as the NC Space Grant/J. Donald Cline Astronomy Scholar. I developed multiple projects and assisted as a mentor to PARI Space Science Lab and Duke TIP high school gifted student program which both took place during my stay. My main focus was the development of the Polaris imaging telescope. This telescope is used to take images of the pulsating variable star Polaris. These readings are used to make seeing estimates for the air column above PARI. The system stores and archives images and analyzes them for magnitude change and movement of the stellar image. In addition to the Polaris project I developed a solar panel voltage and charge monitoring system which involved me working with charge controllers and photovoltaic technology. I developed a charging scheme using Flexmax 60 charge controller. Data is recorded and transmitted via optical fiber for analysis and correlation with solar zenith angle.

The UN Paris Agreement puts in place a legally binding mechanism to increase mitigation action over time. Countries put forward pledges called nationally determined contributions (NDC) whose impact is assessed in global stocktaking exercises. Subsequently, actions can then be strengthened in light of the Paris climate objective: limiting global mean temperature increase to well below 2 °C and pursuing efforts to limit it further to 1.5 °C. However, pledged actions are currently described ambiguously and this complicates the global stocktaking exercise. Here, we systematically explore possible interpretations of NDC assumptions, and show that this results in estimated emissions for 2030 ranging from 47 to 63 GtCO2e yr-1. We show that this uncertainty has critical implications for the feasibility and cost to limit warming well below 2 °C and further to 1.5 °C. Countries are currently working towards clarifying the modalities of future NDCs. We identify salient avenues to reduce the overall uncertainty by about 10 percentage points through simple, technical clarifications regarding energy accounting rules. Remaining uncertainties depend to a large extent on politically valid choices about how NDCs are expressed, and therefore raise the importance of a thorough and robust process that keeps track of where emissions are heading over time.

Our previous study found that PARIS (ZNF746) transcriptionally suppressed transketolase (TKT), a key enzyme in pentose phosphate pathway (PPP) in the substantia nigra (SN) of AAV-PARIS injected mice. In this study, we revealed that PARIS overexpression reprogrammed glucose metabolic pathway, leading to the increment of glycolytic proteins along with TKT reduction in the SN of AAV-PARIS injected mice. Knock-down of TKT in differentiated SH-SY5Y cells led to an increase of glycolytic enzymes and decrease of PPP-related enzymes whereas overexpression of TKT restored PARIS-mediated glucose metabolic shift, suggesting that glucose metabolic alteration by PARIS is TKT-dependent. Inhibition of PPP by either PARIS overexpression or TKT knock-down elevated the level of H 2 O 2 , and diminished NADPH and GSH levels, ultimately triggering the induction of HIF-1α, a master activator of glycolysis. In addition, TKT inhibition by stereotaxic injection of oxythiamine demonstrated slight decrement of dopaminergic neurons (DNs) in SN but not cortical neurons in the cortex, suggesting that TKT might be a survival factor of DNs. In differentiated SH-SY5Y, cell toxicity by GFP-PARIS was partially restored by introduction of Flag-TKT and siRNA-HIF-1α. We also observed the increase of HIF-1α and glycolytic hexokinase 2 in the SN of Parkinson's disease patients. Taken together, these results suggest that PARIS accumulation might distort the balance of glucose metabolism, providing clues for understanding mechanism underlying selective DNs death by PARIS.

Ultraviolet (UV) exposure is one of the most important risk factor for skin cancers. If UV hazard has been evaluated in tropical countries or in some population - children, outdoor activities - little information is available about UV hazard in high latitude towns like Paris, considered as the most 'charismatic city' in the world. To evaluate UV exposure in Paris in spring, in sun and shade, in real life conditions. We evaluated erythemal UV exposure, during four sunny days in May-June in eight Paris touristic sites during peak hours (2 days), and during two walks in touristic downtown of Paris. Measures were performed in sun and shade. UV radiation exposure was evaluated with UV index performed with a 'Solarmeter ultraviolet index (UVI)' and UV dose with 'standard erythema dose' (SED) and 'minimal erythema dose' (MED) calculations. Despite 'average' UVI in sunny conditions, a 4-h sun exposure reaches 13-20 SED and 3-10 MED according to phototype. Clouds were inefficient to protect against UV. Shade of places reduces moderately UVI (50-60%) in forecourts. Exposure during 1-h walk reach at least one MED in real life conditions for skin phototypes I-IV. UV risk for tourist is quite high in spring in Paris. UVI remains high despite high cloud fraction. Shade reduces UVI, but UV protection factor is only 2-3 in large places such as Place Notre Dame and Place Charles de Gaulle. So sun protection campaigns should be proposed, and sun protective strategies could be integrated in urban planning. © 2012 The Authors.

Mutations in PTEN-induced putative kinase 1 (PINK1) and parkin cause autosomal-recessive Parkinson's disease through a common pathway involving mitochondrial quality control. Parkin inactivation leads to accumulation of the parkin interacting substrate (PARIS, ZNF746) that plays an important role in dopamine cell loss through repression of proliferator-activated receptor gamma coactivator-1-alpha (PGC-1α) promoter activity. Here, we show that PARIS links PINK1 and parkin in a common pathway that regulates dopaminergic neuron survival. PINK1 interacts with and phosphorylates serines 322 and 613 of PARIS to control its ubiquitination and clearance by parkin. PINK1 phosphorylation of PARIS alleviates PARIS toxicity, as well as repression of PGC-1α promoter activity. Conditional knockdown of PINK1 in adult mouse brains leads to a progressive loss of dopaminergic neurons in the substantia nigra that is dependent on PARIS. Altogether, these results uncover a function of PINK1 to direct parkin-PARIS-regulated PGC-1α expression and dopaminergic neuronal survival. Copyright © 2017 The Author(s). Published by Elsevier Inc.

Wartime Paris, cirrhosis mortality, and the ceteris paribus assumption.

2002-07-01

This article critiques the ceteris paribus assumption, which tacitly sustains the epidemiologic literature's inference that the sharp decline in cirrhosis mortality observed in Paris during the Second World War derived from a sharp constriction in wine consumption. Paris's wartime circumstances deviate substantially from the "all else being equal" assumption, and at least three other hypotheses for the cirrhosis decline may be contemplated. Historical and statistical review. Wartime Paris underwent tumultuous changes. Wine consumption did decline, but there were, as well, a myriad of other changes in diet and life experience, many involving new or heightened hardships, nutritional, experiential, institutional, health and mortality risks. Three competing hypotheses are presented: (1) A fraction of the candidates for cirrhosis mortality may have fallen to more sudden forms of death; (2) alcoholics, heavy drinkers and Paris's clochard subpopulation may have been differentially likely to become removed from the city's wartime population, whether by self-initiated departure, arrest and deportation, or death from other causes, even murder; and (3) there was mismeasurement in the cirrhosis mortality decline. The alcohol-cirrhosis connection provided the template for the alcohol research effort (now more than 20 years old) aimed at re-establishing scientific recognition of alcohol's direct alcohol-problems-generating associations and causal responsibilities. In a time given to reports of weaker associations of the alcohol-cirrhosis connection, the place and importance of the Paris curve in the wider literature, as regards that connection, remains. For this reason, the Paris findings should be subjected to as much research scrutiny as they undoubtedly deserve.

2015-11-30

The Palaearctic species of Curculionidae: Cyclominae: Hipporhinini conserved at the Muséum national d'Histoire Naturelle, Paris were critically revised in order to recognise the type specimens, select lectotypes or, where necessary, designate neotypes. Out of 135 species whose types were presumably preserved in the MNHN, original type specimens of 116 could be found. The holotypes of 21 species were available, either because originally designated as such, or because the species was unequivocally based on a single specimen; a paratype of another taxon, whose holotype is preserved in another collection, was also examined. The lectotypes of 93 species were designated, and a syntype of another species was also seen. Neotypes of 10 more species were designated, thus leading to a total number of species whose type is conserved at the MNHN to 126. Type specimens of five more species described by French authors, not present in the MNHN but conserved in other museums, were found as well and were included in the paper, with the further designation of three lectotypes. All types treated herein were labelled and photographed.

Monitoring Polaris and Seeing Conditions at PARI

NASA Astrophysics Data System (ADS)

Crawford, April

2016-01-01

Pisgah Astronomical Research Institute (PARI) was originally built by NASA to track and collect data from satellites. The location in the Pisgah National Forest was chosen due to the excellent ability of the surrounding mountains to block radio interference and light pollution. The PARI observatory has been monitoring Polaris for over 10 years and has amassed a large collection of images of the star and those surrounding it. While several telescopes have been used throughout the project, we are currently using a Omni XLT Series Celestron and an SBIG ST-8300M CCD camera with a 0.70 arcsecond/pixel ratio. The software is run on Windows, however, we will be making a switch to Linux and implementing a new program to control the camera. The new images, once converted to a usable format (ST10 to FITS), can be automatically fed into an in-house Java program to track the variability of the star and simultaneously determine the seeing conditions experienced on the campus. Since we have several years worth of data, the program will also be used to provide a history of variability and seeing conditions. We ultimately hope to be able to track the possible changes in variability of Polaris, as it's current location on the HR diagram is being studied. The data could also prove valuable for our on-site scientists and many visiting students to study on campus. We are also developing a relative scale for our seeing conditions, accompanied by FWHM measurements in arcseconds that will can be compared to those of surrounding observatories in mountainous areas.

Images offered Parisians multiple ways to understand and construe the significance of the flood and provided interpretive frameworks to decide the meaning of this event. Investigating three interlocking narratives of ruin, beauty, and fraternité, the article shows how photographs of Paris under water allowed residents to make sense of the destruction but also to imagine the city’s reconstruction. The article concludes with a discussion of the role of visual culture in recovering from urban disasters.

To study the chemical constituents of aerial parts of Paris polyphylla var. chinensis . Aerial parts of Paris polyphylla var. chinensis was extracted with 95% EtOH, and separated and purified by silica gel, RP 18 and Sephadex LH-20 col- umn chromatography. The structures were identified by spectroscopic analysis. A total of ten compounds were isolated and iden- tified as β-sitosterol (1) ergosta-7, 22-dien-3-one (2), β-ecdysone (3), kaempferol (4), daucosterol (5) luteolin (6) calonysterone (7), luteolin-7-O-glucoside (8), quercetin (9), and 3β, 5α, 9α-trihydroxyergosta-7, 22-dien-6-one (10). Compounds 2,6 and 10 are isolated from Paris polyphylla var. chinensis for the first time.

The Paris Hospital in Paris, Arkansas, provided high quality care during its existence from 1910 to 1971, offering a prepaid health care plan from 1920 to 1971. Three generations of Smith doctors were its nucleus, subsidizing the annual losses of the hospital and providing care to all, regardless of ability to pay. The hospital was a community unto itself for the nurses who lived, trained, and worked there. A unique family in the history of medicine in Arkansas, the Smith physicians were well trained, altruistic, compassionate, and conscientious, exemplifying the traditional values of twentieth century medical practice.

Abstract The Myriapoda and Onychophora collection dataset inventories the occurrence records of the collection of myriapods and onychophorans in the Muséum national d’Histoire naturelle, Paris. The dataset currently consists of 202 lots of onychophorans, representing all of those present, and almost ten thousand (9 795) lots of myriapods, representing 33 to 40% of the MNHN Myriapoda collection. This collection, which is of key historic importance, represents the results of two centuries of myriapod and onychophoran studies. The sources of the collection are worldwide, with a high representation for metropolitan France for the myriapods. None of the occurrences are yet georeferenced. Access to the dataset via the data portals of the MNHN and the GBIF has been made possible through the e-ReColNat project (ANR-11-INBS-0004). The Myriapoda and Onychophora collection of MNHN is actively expanding, hence both the collection and dataset are in continuous growth. The dataset can be accessed through the portals of GBIF at http://www.gbif.org/dataset/3287044c-8c48-4ad6-81d4-4908071bc8db and the MNHN at http://science.mnhn.fr/institution/mnhn/collection/my/item/search/form.

We have examined some grains from the Paris meteorite through infrared and Raman micro-spectroscopy in order to investigate their carbonaceous and mineralogical components. In the mid- as well as far-infrared regions, the raw and global spectra of Paris resemble those of CM meteorites. However, we have obtained rather peculiar infrared spectra for some aromatic-rich micron-sized fragments of Paris displaying a very good match between its organic signatures both in the 3.4 {mu}m and 6 {mu}m regions, and the ones observed from the diffuse interstellar medium infrared sources toward the Galactic center, suggesting that this meteorite may have indeed preserved somemore » organic matter of interstellar origin.« less

SUMOylation of the KRAB zinc-finger transcription factor PARIS/ZNF746 regulates its transcriptional activity.

PubMed

Nishida, Tamotsu; Yamada, Yoshiji

2016-05-13

Parkin-interacting substrate (PARIS), a member of the family of Krüppel-associated box (KRAB)-containing zinc-finger transcription factors, is a substrate of the ubiquitin E3 ligase parkin. PARIS represses the expression of peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α), although the underlying mechanisms remain largely unknown. In the present study, we demonstrate that PARIS can be SUMOylated, and its SUMOylation plays a role in the repression of PGC-1a promoter activity. Protein inhibitor of activated STAT y (PIASy) was identified as an interacting protein of PARIS and shown to enhance its SUMOylation. PIASy repressed PGC-1a promoter activity, and this effect was attenuated by PARIS in a manner dependent on its SUMOylation status. Co-expression of SUMO-1 with PIASy completely repressed PGC-1a promoter activity independently of PARIS expression. PARIS-mediated PGC-1a promoter repression depended on the activity of histone deacetylases (HDAC), whereas PIASy repressed the PGC-1a promoter in an HDAC-independent manner. Taken together, these results suggest that PARIS and PIASy modulate PGC-1a gene transcription through distinct molecular mechanisms. Copyright © 2016 Elsevier Inc. All rights reserved.

The international community has set a goal to limit global warming to 2 °C. Limiting global warming to 2 °C is a challenging goal and will entail a dramatic transformation of the global energy system, largely complete by 2040. As part of the work toward this goal, countries have been submitting their Intended Nationally Determined Contributions (INDCs) to the United Nations Framework Convention on Climate Change, indicating their emissions reduction commitments through 2025 or 2030, in advance of the 21st Conference of the Parties (COP21) in Paris in December 2015. In this paper, we use the Global Change Assessment Model (GCAM) to analyze the near versus long-term energy and economic-cost implications of these INDCs. The INDCs imply near-term actions that reduce the level of mitigation needed in the post-2030 period, particularly when compared with an alternative path in which nations are unable to undertake emissions mitigation until after 2030. We find that the latter case could require up to 2300 GW of premature retirements of fossil fuel power plants and up to 2900 GW of additional low-carbon power capacity installations within a five-year period of 2031-2035. INDCs have the effect of reducing premature retirements and new-capacity installations after 2030 by 50% and 34%, respectively. However, if presently announced INDCs were strengthened to achieve greater near-term emissions mitigation, the 2031-2035 transformation could be tempered to require 84% fewer premature retirements of power generation capacity and 56% fewer new-capacity additions. Our results suggest that the INDCs delivered for COP21 in Paris will have important contributions in reducing the challenges of achieving the goal of limiting global warming to 2 °C.

Paris hospitals budget is, in the year 1848, the last before the "Assistance Publique" foundation. 1848 is characterized by important political troubles in Paris and an increased hospital activity. Nevertheless, the budget could suggest a certain wealth. Receipts are mainly based on financial funding and real estate incomes. Expenses are, for one half, linked to patients considered as hosts: food, heating, cleaning, etc. Staff expenses are moderate (12%). Various expenditures are in the same range within the different hospitals. It is interesting to outline the fact that drug expenses have the same importance than 150 years later: 4%. This feature is only an average insofar as general hospital spend about 10% of their budget in drugs as long-term care hospitals spend 1%. This disparity is clearly the proof of an increasing medicalization of Paris hospitals in the middle of the 19th century.

Founded in 1801 at the Hôpital Saint-Louis, Paris, under Jean-Louis Alibert, the French School of Dermatology was initially structured around the French Society of Dermatology (1889) and the organization of two world congresses (Paris 1889, 1900). After World War I, the creation of dermatological societies in the provinces infused French dermatology with new energy. In 1922, the first congress of the French-speaking dermatologists further contributed to the public profile of dermatologists in France. The "Journées de Mars" were initiated in 1961 at the Hôpital Saint-Louis, and in 1975 they went on to become the "Journées dermatologiques de Paris". Pr. Jean Civatte played a key role in their creation and in their organization for 30 years. After 1979, since actual patients could no longer be presented, the organizers of the congress had to change the content of the meeting from clinical presentations to post-graduate teaching and clinical research. From its origins in the form of meetings of French dermatologists in an intimate setting at the Hôpital Saint-Louis, the "Journées dermatologiques de Paris" grew within the ensuing decades into a major scientific event of the French-speaking dermatological community, bringing together more than 4000 participants in December each year.

This paper is the first mortality cohort study undertaken in France to examine the association between fire-fighting and cause of death. The cohort investigated in this study consisted of 830 male members of the Brigade des sapeurs-pompiers de Paris (BSPP). These professional had served for a minimum of 5 years on 1 January 1977. They were monitored for a 14 year period, finishing 1 January 1991. When compared to the average French male, the Paris fire-fighters were found to have a far lower overall mortality (SMR = 0.52 [0.35-0.75]). None of the cause specific SMRs were significantly different from unity. However a greater number of deaths than expected was observed for genito-urinary cancer (SMR = 3.29), digestive cancer (SMR = 1.14), respiratory cancer (SMR = 1.12) and 'cerebrovascular disease' (SMR = 1.16). The low overall SMR observed was consistent with the healthy worker effect. As for cause specific SMRs, they will be confirmed or invalidated by a further analysis as the follow-up of this cohort is being carried on.

Flashbulb memories of the Paris attacks.

Gandolphe, Marie-Charlotte; El Haj, Mohamad

2017-06-01

Flashbulb memories are vivid autobiographical memories of the circumstances where an individual first learns about emotionally significant public events. Our paper assesses whether these memories were triggered by the attacks of Friday 13 November 2015 in Paris. Two hundred and ninety-one participants answered a web-based questionnaire that assessed their memory of the circumstances in which they first learned of the attacks. The questionnaire also assessed vividness, rehearsal, emotion, surprise and novelty. The results showed substantial and vivid recall of the context in which the participants first learned of the event. This recall was associated with fair rehearsal, negative emotional valence, surprise, and novelty. Regression analysis showed that the flashbulb recall was predicted by negative emotion. Negative emotion seems to play a key role in the formation of flashbulb memories, at least those associated with the Paris attacks. © 2017 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

The pattern of recreational drug use has changed over the last decade and now includes a multitude of substances sold as "research chemicals" or new psychoactive substances, "NPS". In France, synthetic cathinones emerged in 2008 (while first mentioned by the French police force in 2007 first alerts among users appeared in 2008) and have grown to be popular drugs of abuse. Under the Official Journal dated 11th June 2010, only mephedrone has been listed as narcotics but "designer drugs" have synthesized new substitute cathinones in order to avoid anti-drug laws. However, since July 2012, in France, all synthetic drugs from the cathinones family have been banned and listed as narcotics following the example of United Kingdom. Despite their recent classification and inclusion on narcotic list, they are readily available on Internet and used widely. Paris Addictovigilance Centre observed a signal of derivate cathinones abuse (21 cases over a two-year period). Paris Addictovigilance Centre and Marmottan Hospital wanted to describe the use of cathinones in the Paris area and alert the health care community about the abuse identification and risk assessment problems of these compounds. After a review of derivated cathinone's chemical structure, pharmacology and toxicology, this article seeks to provide patricians with a clinical description and treatment's modality. Most users of synthetic cathinones will experience euphoria, increased energy, talkativeness, openness and increased sexual arousal. Signs and symptoms of toxicity are consistent with a sympathomimetic toxidrome. The main reasons for care access are psychiatric (hallucinations, psychotic symptoms, agitation) and addiction disorders. Somatic complications were described with various patterns of symptoms such as headache, tachycardia, confusional states, rhabdomyolysis with renal failure or serotonin syndrome. The most important fact is the apparition of the "slam" phenomenon among men who have sex with men

The Biosphere Under Potential Paris Outcomes

Rapid economic and population growth over the last centuries have started to push the Earth out of its Holocene state into the Anthropocene. In this new era, ecosystems across the globe face mounting dual pressure from human land use change (LUC) and climate change (CC). With the Paris Agreement, the international community has committed to holding global warming below 2°C above preindustrial levels, yet current pledges by countries to reduce greenhouse gas emissions appear insufficient to achieve that goal. At the same time, the sustainable development goals strive to reduce inequalities between countries and provide sufficient food, feed, and clean energy to a growing world population likely to reach more than 9 billion by 2050. Here, we present a macro-scale analysis of the projected impacts of both CC and LUC on the terrestrial biosphere over the 21st century using the Representative Concentration Pathways (RCPs) to illustrate possible trajectories following the Paris Agreement. We find that CC may cause major impacts in landscapes covering between 16% and 65% of the global ice-free land surface by the end of the century, depending on the success or failure of achieving the Paris goal. Accounting for LUC impacts in addition, this number increases to 38%-80%. Thus, CC will likely replace LUC as the major driver of ecosystem change unless global warming can be limited to well below 2°C. We also find a substantial risk that impacts of agricultural expansion may offset some of the benefits of ambitious climate protection for ecosystems.

The main goal of the Paris Agreement as stated in Article 2 is 'holding the increase in the global average temperature to well below 2°C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5°C'. Article 4 points to this long-term goal and the need to achieve 'balance between anthropogenic emissions by sources and removals by sinks of greenhouse gases'. This statement on 'greenhouse gas balance' is subject to interpretation, and clarifications are needed to make it operational for national and international climate policies. We study possible interpretations from a scientific perspective and analyse their climatic implications. We clarify how the implications for individual gases depend on the metrics used to relate them. We show that the way in which balance is interpreted, achieved and maintained influences temperature outcomes. Achieving and maintaining net-zero CO 2 -equivalent emissions conventionally calculated using GWP 100 (100-year global warming potential) and including substantial positive contributions from short-lived climate-forcing agents such as methane would result in a sustained decline in global temperature. A modified approach to the use of GWP 100 (that equates constant emissions of short-lived climate forcers with zero sustained emission of CO 2 ) results in global temperatures remaining approximately constant once net-zero CO 2 -equivalent emissions are achieved and maintained. Our paper provides policymakers with an overview of issues and choices that are important to determine which approach is most appropriate in the context of the Paris Agreement.This article is part of the theme issue 'The Paris Agreement: understanding the physical and social challenges for a warming world of 1.5°C above pre-industrial levels'. © 2018 The Authors.

Paris is a commonly used traditional Chinese medicine (TCM), and has antitumor, antibacterial, sedative, analgesic and hemostatic effects. It has been used as an ingredient of 81 Chinese patent medicines, with a wide application and large market demand. Based on the data retrieved from state Intellectual Property Office patent database, a comprehensive analysis was made on Paris patents, so as to explore the current features of Paris patents in the aspects of domestic patent output, development trend, technology field distribution, time dimension, technology growth rate and patent applicant, and reveal the development trend of China's Paris industry. In addition, based on the current Paris resource application and development, a sustainable, multi-channel and multi-level industrial development approach was built. According to the results, studies of Paris in China are at the rapid development period, with a good development trend. However, because wild Paris resources tend to be exhausted, the studies for artificial cultivation technology should be strengthened to promote the industrial development.

In the past few years, there have been many emerging digital library projects, and digitising heritage collections has become a major issue for libraries. Digitisation supports the preservation of collections and facilitates accessibility to the public. Furthermore, the richness and variety of the Paris Observatory's patrimonial collections, which includes ancient books, periodicals, manuscripts, archives, and iconographic documents, makes it an invaluable source for research on the history of astronomy. This is why the Paris Observatory library has started work on a digitisation policy and has since launched several digitisation projects.

In a growing world with more than 7 billion inhabitants and big emerging countries such as China, Brazil and India, emissions of anthropogenic pollutants and greenhouse gases (GHGs) are increasing continuously. Their monitoring and control in megacities have become a major challenge for scientists and public health authorities in environmental research area. The ground-based Fourier transform spectrometer (QualAir FTS[a], model IFS 125HR) of the QualAir platform located in downtown Paris at University Pierre et Marie Curie (UPMC), is a scientific research instrument dedicated to the survey of greenhouse gases (GHGs) and urban air quality. Equipped with a sun-tracker, the remote sensing QualAir FTS relies on solar infrared absorption for monitoring trace gas concentrations and their variability in the Ile-de-France region[b]. Concentrations of atmospheric GHGs, especially CO2, CH4 and N2O, are retrieved by the radiative transfer model PROFFIT[c]. Because Paris is the third largest European megacity, the QualAir FTS can provide new and complementary measurements as compared to existing ground-based FTS network stations (NDACC and TCCON) located in unpolluted environments, such as the TCCON-Orléans station[d] situated in the forest of Orléans (100 km south of Paris). In the effort to integrate QualAir FTS into the TCCON network, simultaneous FTS measurements of GHGs at Paris and Orléans have been performed. We will emphasize on comparisons of CO2 from these two sites. Our comparison will be completed by high-resolved direct CO2 modeling outputs from the Meso-NH model, and ground in situ measurements at different sites (Orléans/Trainou, Paris/Jussieu, Paris/Eiffel Tower). Parts of the data were acquired in the framework of the French CO2-MEGAPARIS project[e, f], whose main goal is to quantify CO2 emissions from the Paris area. The present data intercomparison will help to reduce uncertainties in carbon cycle models and to better characterize regional GHG fluxes

Negative Emissions Technologies, the Paris Agreement, and the Need for a Human-Rights Based Approach

The new Paris Agreement under the United Nations Framework Convention on Climate Change contemplates that its prospective Parties will balance emissions and sinks by 2050 as a means to effectuate the goal of holding temperature increases to well below 2°C from pre-industrial levels, as well as the more aspirational goal of holding temperature increases to 1.5°C. Most of the IPCC's AR5 scenarios that achieve these objectives contemplate the large-scale deployment of so-called "negative emissions technologies," with an emphasis on bioenergy and carbon capture and storage (BECCS), and to a lesser degree afforestation. BECCS could assuredly help society avoid passing critical climatic thresholds, or address overshoot scenarios in this century and beyond. However, it could also profound implications for food production, the status of forests, access to lands for livelihoods by vulnerable populations, and the integrity of critical ecosystems. This, in turn could have serious ramifications for human rights of some of the world's most vulnerable populations, including the rights to food, water, livelihoods and the benefits of biodiversity. The Preamble to the Paris Agreement acknowledges the need to take into consideration the potential impact of responses to climate change, providing that "Parties should, when taking action to address climate change, respect, promote and consider their respective obligations on human rights." This presentation will outline how application of a human rights-based approach to assessing such options could help to reconcile the objectives of ameliorating potential climatic impacts while protecting the human rights of potentially affected individuals and groups. This will include the potential role of Human Rights Impacts Assessments and potential configuration of HRIAs at the national and international level. It will also briefly suggest how to operationalize this approach within the Paris Agreement framework, including institutional

A total of 85 short endoscopic video clips depicting polyps were created and assessed by seven expert endoscopists according to the Paris classification. After a digital training module, the same 85 polyps were assessed again. We calculated the interobserver agreement with a Fleiss kappa and as the proportion of pairwise agreement. The interobserver agreement of the Paris classification among seven experts was moderate with a Fleiss kappa of 0.42 and a mean pairwise agreement of 67%. The proportion of lesions assessed as "flat" by the experts ranged between 13 and 40% (P<0.001). After the digital training, the interobserver agreement did not change (kappa 0.38, pairwise agreement 60%). Our study is the first to validate the Paris classification for polyp morphology. We demonstrated only a moderate interobserver agreement among international Western experts for this classification system. Our data suggest that, in its current version, the use of this classification system in daily practice is questionable and it is unsuitable for comparative endoscopic research. We therefore suggest introduction of a simplification of the classification system.

The epileptic singers of belle époque Paris.

In late 19th century Paris, people with epilepsy were treated alongside those with hysteria in the now famous Salpêtrière Hospital, where both conditions were deemed to have a neurological basis. When Jean Martin Charcot became chief physician at the Salpêtrière Hospital in 1862, he described himself 'in possession of a kind of museum of living pathology whose holdings were virtually inexhaustible'. He opened the doors of his 'living museum' and exhibited his prize specimens to all of Paris. By putting his patients on display, Charcot introduced a vogue for pathology that permeated well beyond the world of medical enquiry and into the public psyche and vernacular. Not only did Charcot's demonstrations provide the inspiration for high culture in the form of operas, plays and novels, they also provided the inspiration for the 'gommeuses epileptiques' (epileptic singers), who entertained the masses at the café concerts. This paper explores the foundations of our current medical approaches to mental illness and epilepsy, with a particular focus on the boundaries that emerged between hysteria and epilepsy in 19th century Paris. These clinical boundaries were both shaped by and reflected in the popular entertainments in the city.

Undocumented Youth Living Between the Lines: Urban Governance, Social Policy, and the Boundaries of Legality in New York City and Paris

NASA Astrophysics Data System (ADS)

Ruszczyk, Stephen P.

This dissertation compares the transition to adulthood of undocumented youth in New York and Paris, along with analysis of the construction of illegality in each city. In both the United States and France, national restrictions against undocumented immigrants increasingly take the form of deportations and limiting access to social rights. New York City and Paris, however, mitigate the national restrictions in important but different ways. They construct "illegality" differently, leading to different young adult outcomes and lived experiences of "illegality." This project uses seven years of multi-site ethnographic data to trace the effects of these mitigated "illegalities" on two dozen (male) youth. We can begin to understand the variation in these undocumented young men's social lives within and between cities by centering on (1) governance structure, the labyrinth of obtaining rights associated with citizenship, (2) citizenship, the possibility of gaining a legal status, steered in particular by civil society actors, and (3) identity, here centered on youths' negotiation of social mobility with the fear of enforcement. Biographical narratives show the shifts in social memberships as youth transition to new countries, new restrictions at adulthood, and new, limiting work. In New York, most social prospects are flattened as future possibilities are whittled down to ones focusing on family and wages. Undocumented status propels New York informants into an accelerated transition to adulthood, as they take on adult responsibilities of work, paying bills, and developing families. In Paris, youth experience more divergent processes of transitioning to adulthood. Those who are more socially integrated use a civil society actor to garner a (temporary) legal status, which does not lead to work opportunities. Those who are less socially integrated face isolation as they wait to gain status and access to better jobs. Paris undocumented youth are thus characterized by a

Ciguatera fish poisoning (CFP) is a food-borne illness due to the consumption of reef fish containing pathogenic toxins. CFP is endemic to tropical areas and may be described in travelers in non-endemic areas. We describe two clusters of autochthonous cases of CFP in Paris, France. They were related to two fish caught in Guadeloupe (French West Indies) and consumed in Paris after being air-transported in a cooler. In both cases, fish flesh was analyzed and the presence of ciguatoxins by mouse bioassay (MBA) was confirmed. The first cluster involved eight individuals among whom five presented gastrointestinal symptoms and four presented neurological symptoms after consuming barracuda flesh (Sphyraena barracuda). The second cluster involved a couple who consumed a grey snapper (Lutjanus griseus). Most of them consulted at different emergency departments in the region of Paris. CFP may be seen in non-traveler patients outside endemic countries resulting from imported species of fish. Thus, CFP may be undiagnosed as physicians are not aware of this tropical disease outside endemic countries. The detection of ciguatoxins by MBA in the French National Reference Laboratory is useful in the confirmation of the diagnosis. © 2014 International Society of Travel Medicine.

2009-01-01

Background The increasing resources available for and number of partners providing health sector aid have stimulated innovations, notably, the Paris Declaration on Aid Effectiveness, which aim to improve aid coordination. In this, one of the first studies to analyse implementation of aid coordination below national level, the aim was to investigate the effect of the Paris Declaration on coordination of health sector aid at the district level in Zambia. Methods The study was carried out in three districts of Zambia. Data were collected via interviews with health centre staff, district managers and officials from the Ministry of Health, and from district action plans, financial reports and accounts, and health centre ledger cards. Four indicators of coordination related to external-partner activity, common arrangements used by external partners and predictability of funding were analysed and assessed in relation to the 2010 targets set by the Paris Declaration. Findings While the activity of external partners at the district level has increased, funding and activities provided by these partners are often not included in local plans. HIV/AIDS support show better integration in planning and implementation at the district level than other support. Regarding common arrangements used for fund disbursement, the share of resources provided as programme-based support is not increasing. The predictability of funds coming from outside the government financing mechanism is low. Conclusion Greater efforts to integrate partners in district level planning and implementation are needed. External partners must improve the predictability of their support and be more proactive in informing the districts about their intended contributions. With the deadline for achieving the targets set by the Paris Declaration fast approaching, it is time for the signatories to accelerate its implementation. PMID:19505300

Implications of possible interpretations of ‘greenhouse gas balance’ in the Paris Agreement

The main goal of the Paris Agreement as stated in Article 2 is ‘holding the increase in the global average temperature to well below 2°C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5°C’. Article 4 points to this long-term goal and the need to achieve ‘balance between anthropogenic emissions by sources and removals by sinks of greenhouse gases'. This statement on ‘greenhouse gas balance’ is subject to interpretation, and clarifications are needed to make it operational for national and international climate policies. We study possible interpretations from a scientific perspective and analyse their climatic implications. We clarify how the implications for individual gases depend on the metrics used to relate them. We show that the way in which balance is interpreted, achieved and maintained influences temperature outcomes. Achieving and maintaining net-zero CO2-equivalent emissions conventionally calculated using GWP100 (100-year global warming potential) and including substantial positive contributions from short-lived climate-forcing agents such as methane would result in a sustained decline in global temperature. A modified approach to the use of GWP100 (that equates constant emissions of short-lived climate forcers with zero sustained emission of CO2) results in global temperatures remaining approximately constant once net-zero CO2-equivalent emissions are achieved and maintained. Our paper provides policymakers with an overview of issues and choices that are important to determine which approach is most appropriate in the context of the Paris Agreement. This article is part of the theme issue ‘The Paris Agreement: understanding the physical and social challenges for a warming world of 1.5°C above pre-industrial levels'. PMID:29610378

The Paris System for Reporting Urinary Cytology represents a significant improvement in classification of urinary specimens. The system acknowledges the difficulty in cytologically diagnosing low-grade urothelial carcinomas and has developed categories to deal with this issue. The system uses six categories: unsatisfactory, negative for high-grade urothelial carcinoma (NHGUC), atypical urothelial cells, suspicious for high-grade urothelial carcinoma, high-grade urothelial carcinoma, other malignancies and a seventh subcategory (low-grade urothelial neoplasm). Three hundred and fifty-seven urine specimens were independently reviewed by four cytopathologists unaware of the previous diagnoses. Each cytopathologist rendered a diagnosis according to the Paris System categories. Agreement was assessed using absolute agreement and weighted chance-corrected agreement (kappa). Disagreements were classified as low impact and high impact based on the potential impact of a misclassification on clinical management. The average absolute agreement was 65% with an average expected agreement of 44%. The average chance-corrected agreement (kappa) was 0.32. Nine hundred and ninety-nine of 1902 comparisons between rater pairs were in agreement, but 12% of comparisons differed by two or more categories for the category NHGUC. Approximately 15% of the disagreements were classified as high clinical impact. Our findings indicated that the scheme recommended by the Paris System shows adequate precision for the category NHGUC, but the other categories demonstrated unacceptable interobserver variability. This low level of diagnostic precision may negatively impact the applicability of the Paris System for widespread clinical application.

Currently, over 50% of the global population lives in urban areas1 and the future population growth is also predicted to occur mostly in urban centers. While emissions of Greenhouse Gases and carbon-based air pollutants can be estimated quite precisely on national scale using fuel consumption statistics, typically to about 3%-40%2, higher uncertainties of 20%-50% are reported3 for urban GHG emissions. Atmospheric observations, when combined with inversion modelling can allow independently assessing such urban emission inventories4. This study investigates how well novel low-resolution FTS observations can be represented within atmospheric transport models used in such inversion systems, which would be the pre-requisite for a future system based on XCO2 observations. A network of five EM27sun instruments5,6was deployed across the Paris Metropolitan region (upwind, downwind and inside of Paris, diameter ca. 40km) for a three week period in spring 2015. Observed XCO2 significantly varies during this period ranging from 400.5ppm to 406ppm. A decrease in XCO2 throughout the day, likely driven by the biogenic CO2 uptake in the region, is recorded at all sites. Both observational and simulated XCO2 also clearly show that the emissions in the Paris region significantly increase XCO2 (0-2ppm), depending on meteorological conditions. The observational data is compared to three configurations of our XCO2 forward model to assess their performance. We find that all simulations and observations agree qualitatively and that the gradient of XCO2 over Paris can also be reproduced quantitatively for specific meteorological conditions and optimal model setup. 1United Nations, Department of Economic and Social Affairs, Population Division (2014).

Gromaire, M C; Chebbo, G; Constant, A

2002-01-01

Previous research on the Marais catchment in Paris demonstrated the very high zinc and cadmium contamination of runoff from zinc roofing. Thus further investigations were aimed at evaluating the relative importance of this type of roofing in Paris and its potential contribution to zinc and cadmium loads in wet weather flows. According to these results, about 40% of the surface of roofs in Paris is covered with rolled zinc (1016 ha), and this proportion is not likely to vary significantly in the next years, due to architectural rules. The Zn and Cd concentrations measured in runoff from these roofs are in accordance with literature

We provide an overview of reductions in the emission of greenhouse gases (GHGs) needed to achieve either the target (1.5 °C warming) or upper limit (2.0 °C warming) of the Paris Climate Agreement. We will show how much energy must be produced, either by renewables that do not emit significant levels of atmospheric GHGs or via carbon capture and sequestration (CCS) coupled to fossil fuel power plants, to meet forecast global energy demand out to 2060. These projections will be based on two modeling frameworks: our empirical model of global climate (EM-GC) and the CMIP 5 GCMs used throughout IPCC (2013). For each framework, we will show estimates of transient climate response to cumulative emission of carbon to place limits on future emission of CO2 via the combustion of fossil fuel. We will also quantify the impact of future atmospheric CH4 on achieving the goals of the Paris Climate Agreement.

For most engineering alloys, the long fatigue crack growth under a certain stress level can be described by the Paris law. The law provides a correlation between the fatigue crack growth rate (FCGR or da/dN), the range of stress intensity factor (ΔK), and the material constants C and m. A well-established test procedure is typically used to determine the Paris law constants C and m, considering standard specimens, notched and pre-cracked. Definition of all the details necessary to obtain feasible and comparable Paris law constants are covered by standards. However, these cost-expensive tests can be replaced by appropriate numerical calculations. In this respect, this paper deals with the numerical determination of Paris law constants for carbon steel using a two-scale model. A micro-model containing the microstructure of a material is generated using the Finite Element Method (FEM) to calculate the fatigue crack growth rate at a crack tip. The model is based on the Tanaka-Mura equation. On the other side, a macro-model serves for the calculation of the stress intensity factor. The analysis yields a relationship between the crack growth rates and the stress intensity factors for defined crack lengths which is then used to determine the Paris law constants.

Children are sensitive to indoor environmental pollution. Up until now there has been a lack of data on air quality in child day care centers. The aim of this study is to document the indoor environment quality of Paris child day care centers by repeated measurements, and to compare pollutant levels in child day care centers with levels in Paris dwellings. We selected 28 child day care centers frequented by a random sample of babies who participated in the PARIS birth cohort environmental investigation, and visited the child day care centers for one week twice in one year. Biological contaminants assessed were fungi, endotoxin, dust mite allergens, and chemical pollutants: aldehydes, volatile organic compounds and nitrogen dioxide (NO2). Relative humidity, temperature, and carbon dioxide levels were measured simultaneously. A standardized questionnaire was used to gather information about the buildings and their inhabitants. Airborne endotoxin levels in child day care centers were higher than those found in Paris dwellings. Dust mite allergens in child day care centers were below the threshold level for sensitization in the majority of samples, and in common with dwelling samples. Penicillium and Cladosporium were the most commonly identified genera fungi. The child day care center indoor/outdoor ratio for most chemical pollutants was above unity except for NO2, the levels for NO2 being significantly higher than those measured in homes. Chemical and biological contamination in child day care centers appears to be low, apart from endotoxin and NO2. Failure to take child exposure in child day care centers into account could result in an overestimation of children's exposure to other pollutants. Copyright © 2011 Elsevier Inc.

The global warming and its adverse effects on the atmosphere, the biosphere, the lithosphere, and the hydrosphere are obvious. Based on this fact, the international community is fully convinced that we need to fix the problem urgently for our survival, good health, and wellbeing. The aim of this article is to promote the awareness about the United Nations (UN) historic 'Paris Agreement on Climate Change (PACC)' which entered into-force on 4 November 2016. The expected impact of PACC on the global average temperature rise by 2100 as well as its role in enabling accomplishment of global sustainable development goals (SDGs) for the people and planet is also highlighted.

Paris terrorist attack: early lessons from the intensivists.

2016-04-08

During the night of 13-14 November, the city of Paris was exposed, within a few hours, to three bomb explosions, four shooting scenes, and one 3-hour hostage-taking of several hundred people causing at least 130 deaths and more than 250 injured victims. Most unstable patients were transferred to the six trauma centers of the Paris area, all members of the TRAUMABASE Group. A rapid adaptation of the organization of trauma patients' admittance was required in all centers to face the particular needs of the situation. Everything went relatively well in all centers, with overall hospital mortality below 2 %. Nevertheless, most physicians nowadays agree that anticipation, teaching, and training are crucial to appropriately face such events. All of us have learned many additional issues from this experience. Following a meeting of the TRAUMABASE Group, the most relevant issues are detailed in the following.

Paris saponins possess anticancer, anti-inflammatory, and antiviral effects. However, the anticancer effect of Paris saponins has not been well elucidated and the mechanisms underlying the potential function of Paris saponins in cancer therapy are needed to be further identify. In this study, we report that saponin compounds isolated from Paris polyphylla exhibited antitumor activity against breast cancer cell lines, MCF-7 and MDA-MB-231. Paris saponin XA-2 induced apoptosis in both cell lines, as evidenced by the activation of caspases and cleavage of Poly (ADP-ribose) polymerase. The ability of XA-2 to induce autophagy was confirmed by acridine orange staining, accumulation of autophagosome-bound Long chain 3 (LC3)-II, and measurement of autophagic flux. XA-2-induced autophagy was observed to promote apoptosis by the combined treatment of breast cancer cell lines with XA-2 and autophagy inhibitors 3-methyladenine and bafilomycin A1, respectively. Moreover, we report a decrease in the levels of Akt/mTOR signaling pathway proteins, such as the phosphorylated forms of Akt, mTOR, P70S6K, and eukaryotic translation initiation factor 4E-binding protein 1 (4EBP1). Taken together, these results provide important insights explaining the anticancer activity of Paris saponins and the potential development of XA-2 as a new therapeutic agent.

In December of 2015 during COP21 meeting in Paris almost 200 countries signed an agreement pledging to reduce their anthropogenic greenhouse gas (GHG) emissions. Recently USA announced plans to withdraw from the agreement. In this study, we estimate an impact of this decision on future climate using the MIT Integrated Global System Model, which consists of the human activity model, Economic Projection and Policy Analysis (EPPA) model, and a climate model of intermediate complexity, the MIT Earth System Model (MESM). For comparison, we also estimated impacts of possible withdrawals of China, Europe or India. In addition to the "no climate policy" scenario, we consider five emissions scenarios: Paris, Paris_no_USA, Paris_no_EUR and so on. Climate simulations were carried out from 1861 to 2005 driven by prescribed changes in GHGs and natural forcings and them continued to 2100 driven by GHG emissions produced by EPPA model. Because Paris agreement only cover the period up to 2030, last five scenarios were created assuming that emissions or carbon intensity will continue to decrease after 2030 at the same rate as in the 2020-2030 period. To account for uncertainty in climate system response to external forcing, we carry out 400 member ensembles on climate simulations for each scenario. Probability distributions for climate parameters are obtained by comparing simulated climate for 1861 to 2010 with observations. Our analysis shows that, full implementation of Paris agreement (under above-descried assumptions) will increase probability of surface air temperature in the last decade of this century increasing by less than 3oC relative to pre-industrial form about 20% for "no climate policy" to about 86%. Withdrawal of USA, China, Europe or India will decrease this probability to about 63, 67, 75 and 82%, respectively.

The Paris prospective birth cohort study was implemented in 2003 to assess environmental/behavioural factors associated with respiratory and allergic disorder occurrence in early childhood. This paper describes the design and sociodemographic features of eligible/enrolled families. Full-term newborns without any medical problem at birth were recruited in five Paris maternity hospitals. They resided in the Paris area and had French speaking mothers. Sample size is at least 3500 infants, and children are followed-up until their sixth birthday. Data collection is based on regular medical and environmental self-administered questionnaires to parents. Information on dwellings is gathered by means of phone questionnaires, and standardized medical examinations are carried out at 18 months and 6 years. Exposure to traffic-related pollution is modelled. At inclusion, some information concerning refusals is gathered in order to describe sociodemographic features of participating families as compared with eligible children. 4115 (63%) out of the 6493 eligible infants are now participating in this study. Participation rate is higher in parents with a high SES (socioeconomic status), for French and European parents, and for > or =25-year-old mothers, but decreases with sibship size. Similar determinants are associated with the distribution of reasons for non-participation. The participation rate in the Paris study is comparable with other similar studies. Finally, giving detailed explanation of the study aims at inclusion, establishing regular mailed and phoned contacts with families, offering free complete medical examinations for the participant child and re-sent missing questionnaires are very important to improve participation at inclusion and during follow-up.

Climate change: The 2015 Paris Agreement thresholds and Mediterranean basin ecosystems.

PubMed

Guiot, Joel; Cramer, Wolfgang

2016-10-28

The United Nations Framework Convention on Climate Change Paris Agreement of December 2015 aims to maintain the global average warming well below 2°C above the preindustrial level. In the Mediterranean basin, recent pollen-based reconstructions of climate and ecosystem variability over the past 10,000 years provide insights regarding the implications of warming thresholds for biodiversity and land-use potential. We compare scenarios of climate-driven future change in land ecosystems with reconstructed ecosystem dynamics during the past 10,000 years. Only a 1.5°C warming scenario permits ecosystems to remain within the Holocene variability. At or above 2°C of warming, climatic change will generate Mediterranean land ecosystem changes that are unmatched in the Holocene, a period characterized by recurring precipitation deficits rather than temperature anomalies.

Trace metal concentrations in forest and lawn soils of Paris region (France) along a gradient of urban pressure

Urban soils differ greatly from natural ones as they are located in areas of intense anthropogenic activity (e.g. pollution, physical disturbance, surface transformation). Urban soils are a crucial component of urban ecosystems, especially in public green spaces, and contribute to many ecosystem services from the mitigation of urban heat island to recreational services. In the last decade, the study of urban soils has emerged as an important frontier in environmental research, at least because of their impact on the quality of life of urban populations, because of the services they deliver and because they are more and more recognized as a valuable resource. One of the key issues is the pollution of urban soils because they receive a variety of deposits from local (vehicle emissions, industrial discharges, domestic heating, waste incineration and other anthropogenic activities) and from remote sources (through atmospheric transport). Typical contaminants include persistent toxic substances, such as trace metals (TMs) that have drawn wide attention due to their long persistence in the environment, their tendency to bioaccumulate in the food chain and their toxicity for humans and other organisms. Concentrations, spatial distributions, dynamics, impacts and sources of TMs (e.g. industry or fossil fuels combustion) have attracted a global interest in urban soils and are the subject of ongoing research (e.g. ecotoxicological urban ecology). Some studies have already documented soil pollution with TMs at both the town and regional scales. So far, several monitoring programs (e.g. National Network for the long term Monitoring of Forest Ecosystem, Regional Monitoring Quality of Soil in France) and studies have been carried out on a national scale to measure the ranges of TM concentrations and natural background values in French soils. These studies have focused on French agricultural and forest soils and have not tackled urban soils. No study has described TM

Mutations in parkin lead to early-onset autosomal recessive Parkinson’s disease (PD) and inactivation of parkin is thought to contribute to sporadic PD. Adult knockout of parkin in the ventral midbrain of mice leads to an age-dependent loss of dopamine neurons that is dependent on the accumulation of parkin interacting substrate (PARIS), zinc finger protein 746 (ZNF746), and its transcriptional repression of PGC-1α. Here we show that adult knockout of parkin in mouse ventral midbrain leads to decreases in mitochondrial size, number, and protein markers consistent with a defect in mitochondrial biogenesis. This decrease in mitochondrial mass is prevented by short hairpin RNA knockdown of PARIS. PARIS overexpression in mouse ventral midbrain leads to decreases in mitochondrial number and protein markers and PGC-1α–dependent deficits in mitochondrial respiration. Taken together, these results suggest that parkin loss impairs mitochondrial biogenesis, leading to declining function of the mitochondrial pool and cell death. PMID:26324925

To evaluate today's trace element atmospheric concentrations in large urban areas, an atmospheric survey was carried out for 18 months, from March 2002 to September 2003, in Saclay, nearby Paris. The total suspended particulate matter (TSP) was collected continuously on quartz fibre filters. The TSP contents were determined for 36 elements (including Ag, Bi, Mo and Sb) using two analytical methods: Instrumental Neutron Activation Analysis (INAA) and Inductively Coupled Plasma Mass Spectrometry (ICP-MS). The measured concentrations were in agreement within the uncertainties with the certified values for the polycarbonate reference material filter SRM-2783 (National Institute for Standard Technology NIST, USA). The measured concentrations were significantly lower than the recommended atmospheric concentrations. In 2003, the Pb atmospheric level at Saclay was 15 ng/m 3, compared to the 500 ng/m 3 guideline level and to the 200 ng/m 3 observed value in 1994. The typical urban background TSP values of 1-2, 0.2-1, 4-6, 10-30 and 3-5 ng/m 3 for As, Co, Cr, Cu and Sb, respectively, were inferred from this study and were compared with the literature data. The typical urban background TSP concentrations could not be realised for Cd, Pb and Zn, since these air concentrations are highly influenced by local features. The Zn concentrations and Zn/Pb ratio observed in Saclay represented a characteristic fingerprint of the exceptionally large extent of zinc-made roofs in Paris and its suburbs. The traffic-related origin of Ba, Cr, Cu, Pb and Sb was demonstrated, while the atmospheric source(s) of Ag was not identified.

Objectives. We investigated the association between average income or deprivation and infant mortality rate across neighborhoods of 4 world cities. Methods. Using a maximum likelihood negative binomial regression model that controls for births, we analyzed data for 1988–1992 and 1993–1997. Results. In Manhattan, for both periods, we found an association (.05% significance level) between income and infant mortality. In Tokyo, for both periods, and in Paris and London for period 1, we found none (5% significance level). For period 2, the association just missed statistical significance for Paris, whereas for London it was significant (5% level). Conclusions. In stark contrast to Tokyo, Paris, and London, the association of income and infant mortality rate was strongly evident in Manhattan. PMID:15623865

Using data from the 2004 and 2005 Consumer Expenditure Surveys (CES) comprising of 15,000 respondents, this study examines two research questions. The first of these considers the demographic differences between households whose members lose money playing the lottery and/or engaging in pari-mutuel betting and those whose members do not lose money participating in such activities. The second assesses demographic differences among households whose members lose money playing the lottery and/or engaging in pari-mutuel betting. It was found that respondents living in money-losing households are slightly older, better off financially, more likely to be married or divorced, more likely to live in a state with at least one legal casino and more likely to live in the Northeast than respondents living in non-money-losing households. Among those living in money-losing households, the least wealthy and African American respondents are more likely to lose a higher proportion of their respective incomes purchasing lottery tickets and engaging in pari-mutuel betting than wealthier respondents and whites.

The Paris area is strongly urbanized and is exposed to atmospheric pollution events. To understand the chemical and physical processes that are taking place in this area it is necessary to describe correctly the atmospheric boundary-layer (ABL) dynamics and the ABL height evolution. During the winter of 1994-1995, within the framework of the Etude de la Couche Limite Atmosphérique en Agglomération Parisienne (ECLAP) experiment, the vertical structure of the ABL over Paris and its immediate suburbs was extensively documented by means of lidar measurements. We present methods suited for precise determination of the ABL structure's temporal evolution in a dynamic environment as complex as the Paris area. The purpose is to identify a method that can be used on a large set of lidar data. We compare commonly used methods that permit ABL height retrievals from backscatter lidar signals under different meteorological conditions. Incorrect tracking of the ABL depth's diurnal cycle caused by limitations in the methods is analyzed. The study uses four days of the ECLAP experiment characterized by different meteorological and synoptic conditions.

Challenges for the geosciences after the Paris agreement

The world's governments agreed to limit global mean temperature change to below 2 °C or 1.5°C compared with pre-industrial levels in Paris. These warming targets are often perceived by the public as a universally accepted goal, identified by scientists as a safe limit that avoids dangerous climate change. This perception is incorrect: no scientific assessment has clearly justified or defended 2°C as a safe level of warming, and indeed, this is not a problem that science alone can address. We argue that global temperature is the best climate target quantity, but it is unclear what level can be considered safe. However, irrespective of the target, the concept of cumulative carbon implies that substantial and sustained emission reductions are required to limit climate change to temperature levels that are currently being considered safe. The Paris agreement poses many open questions to the geoscience community: the impacts of a temperature overshoot, the limits of negative emissions, and the role of radiative forcings other than carbon dioxide need to be better understood. Treating uncertainties, incorporating risk, and linking local impacts and development objectives to global climate goals also remain major open issues that need to be tackled in a continued dialogue with science communities. The negotiations up to Paris and the 2 °C target have been useful for anchoring discussions, but ineffective in triggering the required emission reductions; the debates on considering different targets are strongly at odds with the current real-world level of action. These debates are moot, however, as the decisions that need to be taken now to limit warming to 1.5 or 2 °C are very similar. We need to agree how to start, not where to end mitigation.

We describe the design and operation of an apparatus for loading gases into the sample volume of the Paris-Edinburgh press at room temperature and high pressure. The system can be used for studies of samples loaded as pure or mixed gases as well as for loading gases as pressure-transmitting media in neutron-scattering experiments. The apparatus consists of a high-pressure vessel and an anvil holder with a clamp mechanism. The vessel, designed to operate at gas pressures of up to 150 MPa, is used for applying the load onto the anvils located inside the clamp. This initial load is sufficient formore » sealing the pressurized gas inside the sample containing gasket. The clamp containing the anvils and the sample is then transferred into the Paris-Edinburgh press by which further load can be applied to the sample. The clamp has apertures for scattered neutron beams and remains in the press for the duration of the experiment. The performance of the gas loading system is illustrated with the results of neutron-diffraction experiments on compressed nitrogen.« less

About 80% of global CO2 emissions come from punctual sources such as megacities. Among those, Paris is the third megacity in Europe. However, the estimates of urban CO2 emissions are based on activity proxies and benchmarked emission factors, leading to uncertainties as high as several tenths of percents in some sectors of bottom-up CO2 emissions inventories. Since 2009, the CO2-Megaparis project aims to quantify CO2 emissions from Paris using a top-down approach based on a synergy between atmospheric observations and modeling. A mini-network of 3 stations was developed by LSCE in Paris agglomeration within the infrastructure of the air quality monitoring agency of Paris region, AIRPARIF, completing 2 other stations from the ICOS network leaded at LSCE. The mean CO2 concentration dome over Paris in the mid-afternoon over 1 year of data is about 2.2 ppm, and is strongly wind speed and direction dependent. Analysis of correlations between CO2, CO and 14C02 was carried out and a comparison to available inventories will be presented. Direct modeling of CO2 at a very fine resolution (2x2 km2, 1h) was performed by CNRM and matched well with observations. Results from inverse modeling will be presented. Furthermore, we conducted a campaign using lidar facilities showing that due to the effect of the urban heat island, the boundary layer height (a key parameter in assessing CO2 fluxes from the atmospheric approach) is 10 to 40% time higher in Paris than in surrounding rural areas. Also, a sonic anemometer and a 10 Hz CO2 analyzer were deployed to assess CO2 fluxes from observations, as well as CO2 flux analyzers on crops. Using the data from this instrumentation, a mass balance calculation was carried out and allowed the identification and quantification of Paris CO2 traffic plume to a rural region, about 100 km south of Paris, that matched well with inventories. Finally, an attempt of defining the strengths and weaknesses of the atmospheric approach to quantify urban CO2

Italian neurologist Vincenzo Neri was able to discover cinematography at the beginning of his career, when in 1908 he went to Paris to learn and improve his clinical background by following neurological cases at La Pitié with Joseph Babinski, who became his teacher and friend. While in Paris, Neri photographed and filmed several patients of famous neurologists, such as Babinski and Pierre Marie. His stills were published in several important French neurological journals and medical texts. He also collaborated with Georges Mendel, who helped Doyen film the first known surgical operation in the history of cinema. In 1910, when he came back to Bologna, he continued in his clinical activities and, for 50 years, slowly developed a huge archive of films, images, and prints of neurological, psychiatric, and orthopedic cases. This archive was extremely helpful to Neri, who especially needed to analyze neurological disorders and to differentiate them from functional conditions in order to understand clinical signs, rules, and mechanisms.

Evaluation of bottom-up and downscaled emission inventories for Paris and consequences for estimating urban air pollution increments

Since a major part of the Earth's population lives in cities, it is of great importance to correctly characterise the air pollution levels over these urban areas. Many studies in the past have already been dedicated to this subject and have determined so-called urban increments: the impact of large cities on the air pollution levels. The impact of large cities on air pollution levels usually is determined with models driven by so-called downscaled emission inventories. In these inventories official country total emissions are gridded using information on for example population density and location of industries and roads. The question is how accurate are the downscaled inventories over cities or large urban areas. Within the EU FP 7 project MEGAPOLI project a new emission inventory has been produced including refined local emission data for two European megacities (Paris, London) and two urban conglomerations (the Po valley, Italy and the Rhine-Ruhr region, Germany) based on a bottom-up approach. The inventory has comparable national totals but remarkable difference at the city scale. Such a bottom up inventory is thought to be more accurate as it contains local knowledge. Within this study we compared modelled nitrogen dioxide (NO2) and particulate matter (PM) concentrations from the LOTOS-EUROS chemistry transport model driven by a conventional downscaled emission inventory (TNO-MACC inventory) with the concentrations from the same model driven by the new MEGAPOLI 'bottom-up' emission inventory focusing on the Paris region. Model predictions for Paris significantly improve using the new Megapoli inventory. Both the emissions as well as the simulated average concentrations of PM over urban sites in Paris are much lower due to the different spatial distribution of the anthropogenic emissions. The difference for the nearby rural stations is small implicating that also the urban increment for PM simulated using the bottom-up emission inventory is much smaller than

The amino acid and hydrocarbon contents of the Paris meteorite, the most primitive CM chondrite

NASA Astrophysics Data System (ADS)

Martins, Zita; Modica, Paola; Zanda, Brigitte; Le Sergeant d'Hendecourt, Louis

2015-04-01

The Paris meteorite is reported to be the least aqueously altered CM chondrite [1,2], and to have experienced only weak thermal metamorphism [2-5]. The IR spectra of some of Paris' fragments suggest a primitive origin for the organic matter in this meteorite, similar to the spectra from solid-state materials in molecular clouds [6]. Most of the micron-sized organic particles present in the Paris matrix exhibit 0 < δD <2000‰ [7,8]. In order to understand the effect of aqueous alteration and thermal metamorphism on the abundance and distribution of meteoritic soluble organic matter, we have analyzed for the first time the amino acid and hydrocarbon contents of the Paris meteorite [9]. Extensive aqueous alteration in the parent body of carbonaceous meteorites may result in the decomposition of α-amino acids and the synthesis of β- and γ-amino acids. When plotted with several CM chondrites, Paris has the lowest relative abundance of β-alanine/glycine (0.15) for a CM chondrite, which fits with the relative abundance of β-alanine/glycine increasing with increasing aqueous alteration [10,11]. In addition, our results show that the isovaline detected in this meteorite is racemic (D/L= 0.99 ± 0.08; L-enantiomer excess (%) = 0.35 ± 0.5; corrected D/L = 1.03; corrected L-enantiomer excess (%) = -1.4 ± 2.6). Although aqueous alteration does not create by itself an isovaline asymmetry, it may amplify a small enantiomeric excess. Therefore, our data may support the hypothesis that aqueous alteration is responsible for the high L-enantiomer excess of isovaline observed in the most aqueously altered carbonaceous meteorites [12,13]. Paris has n-alkanes ranging from C16 to C25 and 3- to 5-ring non-alkylated polycyclic aromatic hydrocarbons (PAHs). The lack of alkylated PAHs in Paris seems to be related to the low degree of aqueous alteration on its parent body [9,14]. The extra-terrestrial aliphatic and aromatic hydrocarbon content of Paris may have an interstellar origin

Discussions about the modernisation and reform of the Hôtel Dieu in Paris concerning the catastrophic fire of 1772 there were followed very closely in Prussia and other German countries, though for a long time this had only slight consequences for modernising developments in the hospitals of Berlin or other administrative capitals of Germany. In contrast to this, the Hôpital Lariboisière was praised as a model example in Germany soon after its completion in 1854 after the pre-revolutionary Parisian plans, was imitated in Berlin twenty years later. It must be added that in Prussia great importance was attached to stricter requirements for hygiene and ventilation than in Paris. This was clearly demonstrated barely in the construction of the pavilionhospital in Berlin-Friedrichshain (1868-1874) with an extremely decentralized layout. It was not until two generations later with the completion of the municipal hospital Westend in Charlottenburg (1904-1907), a suburb of Berlin, that a slightly modified "Lariboisière" in the Wilheminian brick Baroque style was built. Similarily the acceptance of high-rise construction was, compared with Paris, considerably delayed on the German hospital scene. Whereas in the USA and France plans had been made for high-rise hospitals from the 1920s on and realized by 1935, as with the Hôpital Beaujon in Paris (1932-1935), there were fundamental reservations about them in Germany. As a result, this conception of the structure, with an effective concentration of inpatient care in towers together with separate low-rise buildings for functions such as treatment and diagnosis, only gradually gained acceptance in Germany at the end of the 1960s. On the other hand, German architects such as Hermann Distel (1875-1946) or Ernst Kopp (1890-1962), had already, indeed before the Second World War, promoted the high-rise type for inpatient care on theoretical grounds. In addition, two hospitals providing medical care within in Berlin, Martin

The present study aims at identifying and apportioning the major sources of fine aerosols in Paris (France) - the second largest megacity in Europe -, and determining their geographical origins. It is based on the daily chemical composition of PM2.5 characterised during one year at an urban background site of Paris (Bressi et al., 2013). Positive Matrix Factorization (EPA PMF3.0) was used to identify and apportion the sources of fine aerosols; bootstrapping was performed to determine the adequate number of PMF factors, and statistics (root mean square error, coefficient of determination, etc.) were examined to better model PM2.5 mass and chemical components. Potential Source Contribution Function (PSCF) and Conditional Probability Function (CPF) allowed the geographical origins of the sources to be assessed; special attention was paid to implement suitable weighting functions. Seven factors named ammonium sulfate (A.S.) rich factor, ammonium nitrate (A.N.) rich factor, heavy oil combustion, road traffic, biomass burning, marine aerosols and metals industry were identified; a detailed discussion of their chemical characteristics is reported. They respectively contribute 27, 24, 17, 14, 12, 6 and 1% of PM2.5 mass (14.7 μg m-3) on the annual average; their seasonal variability is discussed. The A.S. and A.N. rich factors have undergone north-eastward mid- or long-range transport from Continental Europe, heavy oil combustion mainly stems from northern France and the English Channel, whereas road traffic and biomass burning are primarily locally emitted. Therefore, on average more than half of PM2.5 mass measured in the city of Paris is due to mid- or long-range transport of secondary aerosols stemming from continental Europe, whereas local sources only contribute a quarter of the annual averaged mass. These results imply that fine aerosols abatement policies conducted at the local scale may not be sufficient to notably reduce PM2.5 levels at urban background sites in

Education is one major public service in which quasi-markets and other choice-based mechanisms are now established methods of delivery. The types of school people choose, and the extent to which their choices are realized, have a fundamental impact on the outcomes of any mechanism of school choice. In this article, we provide a comparative analysis of the school choice strategies of middle-class families in London and Paris. We draw on approximately 200 in-depth interviews carried out across the two cities. This enables us to investigate the extent to which middle-class school choice strategies transcend the institutional context provided by both the local (state and private) schools market and national education policy in England and France. We discuss these findings in the context of current school choice policy and consider their implications for future policy design. PMID:25750467

This paper presents a survey on soil Pb contamination around Paris (France) using the French soil monitoring network. The first aim of this study is to estimate the total amount of anthropogenic Pb inputs in soils and to distinguish Pb due to diffuse pollution from geochemical background Pb. Secondly, this study tries to find the main controlling factors of the spatial distribution of anthropogenic Pb. We used the technique of relative topsoil enhancement to evaluate the anthropogenic stock of Pb and we performed lognormal kriging to map Pb regional distribution. The results show a strong gradient of anthropogenic stock of Pb around the urban Paris area. We estimate a total amount of anthropogenic stock of Pb close to 143,000 metric tons, which corresponds to an average accumulation of 5.9 t km(-2). Our study suggests that a grid-based survey can help to quantify diffuse Pb contamination by using robust techniques of calculation and that it might also be used to validate predictions of deposition models.

2004-02-01

Over a period of two years (2000-2001), sediment samples were extracted from 40 silt traps (STs) spread through the combined sewer system of Paris. All sediment samples were analysed for physico-chemical parameters (pH, organic matter content, grain size distribution), with total hydrocarbons (THs) and 16 polycyclic aromatic hydrocarbons (PAHs) selected from the priority list of the US-EPA. The two main objectives of the study were (1) to determine the hydrocarbon contamination levels in the sediments of the Paris combined sewer system and (2) to investigate the PAH fingerprints in order to assess their spatial variability and to elucidate the PAH origins. The results show that there is some important inter-site and intra-site variations in hydrocarbon contents. Despite this variability, TH and PAH contamination levels (50th percentile) in the Parisian sewer sediment are estimated at 530 and 18 microg g(-1), respectively. The investigation of the aromatic compound distributions in all of the 40 STs has underlined that there is, at the Paris sewer system scale, a homogeneous PAH background pollution. Moreover, the study of the PAH fingerprints, using specific ratios, suggests the predominance of a pyrolytic origin for those PAHs fixed to the sewer sediment.

The terrorist attacks (fusillades and suicide attacks) in Paris on 13 November 2015 have had a major psychic impact on all individuals directly or secondarily exposed to them. Medico-psychological unit (CUMP) of the Paris Île-de-France region's immediate care services were immediately mobilized and rapidly strengthened by all regional medico-psychological units (CUMP) throughout the country. Psychological assistance has been provided in several key points of Paris and specifically in the 11th district City Hall of Paris where Lyon's Medico-psychological unit was located. These specific immediate psychological assistances, referred to as a "defusing process" by the medico-psychological unit (CUMP), are mostly devoted to provide the victims with an entry point to a psychological healthcare relationship and give them a first sense of soothing and relief even though they do not prevent further psychological care follow up for the victims. Nonetheless, the potential therapeutic effect of this "defusing process" has not yet been sufficiently established nor demonstrated by any scientific study. A phoning survey was carried out one-month post-terrorist attacks and interviewed the 129 victims who benefited from the "defusing process" conducted by Lyon's medico-psychological unit (CUMP) in order to collect data and assess its effects. These people, whether directly exposed, bereaved relatives or witnesses, whose average age is 35, are mostly living in the Île-de-France region. Most of them present a high score on the IES-R scale, whether they were directly exposed, bereaved relatives or witnesses. Almost all of them (96.5%) experienced at least one medical care contact within this one-month post-trauma period with psychotropic medication for 37% of them. Regarding the defusing conducted by Lyon's medico-psychological unit (CUMP) in the 11th district City Hall of Paris, it appears that 93% of the victims who were looked after indicated that they were satisfied and 87.4% of

The analysis included 108,114 children whose Health Book (carnet de santé) included sociodemographic data and the presence of at least one diphtheria-tetanus-polio vaccination. Among these targeted children, 66,597 (61.6%) had started a vaccination against hepatitis B, 61,190 (56.6%) were considered "vaccinated" (at least three doses), and 47,489 (43.9%) "adequately vaccinated" (at least three doses respecting the prescribed intervals between injections). The sociodemographic factors associated with hepatitis B coverage were as follows: Paris arrondissement where the child attended school, year, and country of birth. Nearly 40% of the children in this cohort had not been vaccinated against hepatitis B before beginning first grade. They have now become adolescents aged 12-17 years. Current data indicate that only one-third of them have benefited from the catch-up campaign. This finding reinforces the need for vigilance on the vaccination status of adolescents against hepatitis B. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

Under the Paris Agreement, parties set and implement their own emissions targets as nationally determined contributions (NDCs) to tackle climate change. International carbon emissions trading is expected to reduce global mitigation costs. Here, we show the benefit of emissions trading under both NDCs and a more ambitious reduction scenario consistent with the 2 °C goal. The results show that the global welfare loss, which was measured based on estimated household consumption change in 2030, decreased by 75% (from 0.47% to 0.16%), as a consequence of achieving NDCs through emissions trading. Furthermore, achieving the 2 °C targets without emissions trading led to a global welfare loss of 1.4%-3.4%, depending on the burden-sharing scheme used, whereas emissions trading reduced the loss to around 1.5% (from 1.4% to 1.7%). These results indicate that emissions trading is a valuable option for the international system, enabling NDCs and more ambitious targets to be achieved in a cost-effective manner.

About 80% of global CO2 emissions come from punctual sources such as megacities. Among those, Paris is the third megacity in Europe. However, the estimates of urban CO2 emissions are based on activity proxies and benchmarked emission factors, leading to uncertainties as high as several tenths of percents in some sectors of bottom-up CO2 emissions inventories. Since 2009, the CO2-Megaparis project aims to quantify CO2 emissions from Paris using a top-down approach based on a synergy between atmospheric observations and modeling. A mini-network of 3 stations was developed by LSCE in Paris agglomeration within the infrastructure of the air quality monitoring agency of Paris region, AIRPARIF, completing 2 other stations from the ICOS network leaded at LSCE. The mean CO2 concentration dome over Paris in the mid-afternoon over 1 year of data is about 2.2 ppm, and is strongly wind speed and direction dependent. Analysis of correlations between CO2, CO and 14C02 was carried out and a comparison to available inventories will be presented. Direct modeling of CO2 at a very fine resolution (2x2 km2, 1h) was performed by CNRM and matched well with observations. Results from inverse modeling will be presented. Furthermore, we conducted a campaign using lidar facilities showing that due to the effect of the urban heat island, the boundary layer height (a key parameter in assessing CO2 fluxes from the atmospheric approach) is 10 to 40% time higher in Paris than in surrounding rural areas. Also, a sonic anemometer and a 10 Hz CO2 analyzer were deployed to assess CO2 fluxes from observations, as well as CO2 flux analyzers on crops. Using the data from this instrumentation, a mass balance calculation was carried out and allowed the identification and quantification of Paris CO2 traffic plume to a rural region, about 100 km south of Paris, that matched well with inventories. Finally, an attempt of defining the strengths and weaknesses of the atmospheric approach to quantify urban CO2

The Eiffel Tower and its shadow can be seen next to the Seine in the left middle of this ASTER image of Paris. Based on the length of the shadow and the solar elevation angle of 59 degrees, we can calculate its height as 324 meters (1,054 feet), compared to its actual height of 303 meters (985 feet). Acquired on July 23, 2000, this image covers an area 23 kilometers (15 miles) wide and 20 kilometers (13 miles) long in three bands of the reflected visible and infrared wavelength region. Known as the City of Light, Paris has been extolled for centuries as one of the great cities of the world. Its location on the Seine River, at a strategic crossroads of land and river routes, has been the key to its expansion since the Parisii tribe first settled here in the 3rd century B.C.

Air ion concentrations influence new particle formation and consequently the global aerosol as potential cloud condensation nuclei. We aimed to evaluate air ion concentrations and characteristics of new particle formation events (NPF) in the megacity of Paris, France, within the MEGAPOLI (Megacities: Emissions, urban, regional and Global Atmospheric Pollution and climate effects, and Integrated tools for assessment and mitigation) project. We measured air ion number size distributions (0.8-42 nm) with an air ion spectrometer and fine particle number concentrations (> 6 nm) with a twin differential mobility particle sizer in an urban site of Paris between 26 June 2009 and 4 October 2010. Air ions were size classified as small (0.8-2 nm), intermediate (2-7 nm), and large (7-20 nm). The median concentrations of small and large ions were 670 and 680 cm-3, respectively, (sum of positive and negative polarities), whereas the median concentration of intermediate ions was only 20 cm-3, as these ions were mostly present during new particle formation bursts, i.e. when gas-to-particle conversion produced fresh aerosol particles from gas phase precursors. During peaks in traffic-related particle number, the concentrations of small and intermediate ions decreased, whereas the concentrations of large ions increased. Seasonal variations affected the ion population differently, with respect to their size and polarity. NPF was observed in 13 % of the days, being most frequent in spring and late summer (April, May, July, and August). The results also suggest that NPF was favoured on the weekends in comparison to workdays, likely due to the lower levels of condensation sinks in the mornings of weekends (CS weekdays 09:00: 18 × 10-3 s-1; CS weekend 09:00: 8 × 10-3 s-1). The median growth rates (GR) of ions during the NPF events varied between 3 and 7 nm h-1, increasing with the ion size and being higher on workdays than on weekends for intermediate and large ions. The median GR of

Reporting of incidents or near incidents because of medical devices in French hospitals relies on procedures following European and national guidelines. The authors intend to evaluate hospital staff knowledge on these surveillance procedures as a marker of appropriate application. A telephone survey is conducted on a sample of Paris University hospital staff (n = 327) using a structured questionnaire. Two-hundred sixteen persons completed the questionnaire. The response rate was lower among physicians, especially surgeons paid on an hourly basis. Rates of correct answers were different according to age, seniority, job, and department categories. Physicians and nurses correctly answered questions on theoretical knowledge more often than the other job categories. However, on questions dealing with actual practice conditions, correct answers depended more on age and seniority with a U-shaped distribution (minimum rates in intermediate categories of age and seniority).

The United Nations' Paris Agreement includes the aim of pursuing efforts to limit global warming to only 1.5 °C above pre-industrial levels. However, it is not clear what the resulting climate would look like across the globe and over time. Here we show that trajectories towards a '1.5 °C warmer world' may result in vastly different outcomes at regional scales, owing to variations in the pace and location of climate change and their interactions with society's mitigation, adaptation and vulnerabilities to climate change. Pursuing policies that are considered to be consistent with the 1.5 °C aim will not completely remove the risk of global temperatures being much higher or of some regional extremes reaching dangerous levels for ecosystems and societies over the coming decades.

The Hydrology, Meteorology, and Complexity laboratory of École des Ponts ParisTech (hmco.enpc.fr) has made a data set of optical disdrometer measurements available that come from a campaign involving three collocated devices from two different manufacturers, relying on different underlying technologies (one Campbell Scientific PWS100 and two OTT Parsivel2 instruments). The campaign took place in January-February 2016 in the Paris area (France). Disdrometers provide access to information on the size and velocity of drops falling through the sampling area of the devices of roughly a few tens of cm2. It enables the drop size distribution to be estimated and rainfall microphysics, kinetic energy, or radar quantities, for example, to be studied further. Raw data, i.e. basically a matrix containing a number of drops according to classes of size and velocity, along with more aggregated ones, such as the rain rate or drop size distribution with filtering, are available.

What would it take to achieve the Paris temperature targets?

The 2015 Paris Agreement aims to limit warming to 2 or 1.5°C above preindustrial level, although combined Intended Nationally Determined Contributions (INDCs) are likely insufficient to achieve these targets. We propose a set of idealized emission pathways consistent with the targets. If countries reduce emissions in line with their INDCs, the 2°C threshold could be avoided only if net zero greenhouse gas emissions (GHGEs) are achieved by 2085 and late century negative emissions are considerably in excess of those assumed in Representative Concentration Pathway (RCP) 2.6 (net -5 Gt CO2/yr, compared with -1.5 Gt CO2/yr in RCP2.6). More aggressive near-term reductions would allow 2°C to be avoided with less end-of-century carbon removal capacity. A 10% cut in GHGEs by 2030 (relative to 2015) could likely achieve 2°C with RCP2.6 level negative emissions. The 1.5°C target requires GHGEs to be reduced by almost a third by 2030 and net zero by 2050, while a 50 year overshoot of 1.5°C allows net zero GHGEs by 2060.

Securing access to energy for a growing population under the international commitment of reduction of greenhouse emissions requires increasing the contribution of renewable sources to the global share. Hydropower energy, which accounts for >80% of green energy, is experiencing a boom fostered by international investment mainly in developing countries. This boom could be further accelerated by the recent climate agreement reached in Paris. Despite its flexibility, hydropower production entails social, economic and ecological risks that need to be carefully considered before investing in the development of potentially thousands of planned hydropower projects worldwide. This is especially relevant given the weak or nonexistent legislation that regulates hydropower project approval and construction in many countries. I highlight the need for adequate policy to provide the Paris Agreement with new financial and planning mechanisms to avoid further and irreversible damage to freshwater ecosystem services and biodiversity. © 2017 John Wiley & Sons Ltd.

Long-term damage to glass in Paris in a changing environment.

Ionescu, Anda; Lefèvre, Roger-Alexandre; Brimblecombe, Peter; Grossi, Carlota M

2012-08-01

Glass weathering depends mainly on its chemical composition: Si-Ca-K mediaeval glass is low durable, while Si-Ca-Na Roman as well as modern glass are very durable. Mediaeval glass is subject to the superficial leaching of K and Ca ions leading to the formation of a hydrated silica-gel layer. Both types of glass develop a superficial stratum of deposited atmospheric particles cemented by crystals of gypsum (and syngenite in the case of Si-Ca-K glass), leading to an impairment of the optical properties: decrease of transparency and increase of haze. Dose-response functions established for the two types of glass reveal that haze depends only on pollution parameters (PM, SO(2), NO(2)), while leaching depends both on pollution and climate parameters (RH, T, SO(2), NO(2)). Instrumental records are available for temperature in Paris from 1800. Air pollution in Paris was estimated from statistics of fuel use from 1875 to 1943, measurements that started in the 1950s and projections across the 21st century. The estimated annual rate of haze development indicates a gradual rise from the 16th century. The increasing importance of coal as a fuel through the 19th century and enhanced sulphur dioxide concentration make a rapid increase in haze formation, which reaches a peak about 1950. The likely damage to mediaeval glass follows a rather similar pattern. The period of damage from aggressive pollutants looks later and for a briefer time in Paris than in London.

During the nineteenth century, tumultuous relationships existed between the public authorities, the Paris Medical Faculty, its students and teachers, the medical and the popular press. These agitated debates concerned the value of teaching history in medical studies. This paper aims to follow the main steps of these debates through various texts: the new plan for the structure of Medicine in France (1790); the creation (1795), suppression (1822) and restoration (1870) of the Paris chair of the History of Medicine; Guerin's report (1830) concerning the a new reorganization of the Paris Medical Faculty; Dr. Dezeimeris's petitions (1837) addressed to the French Minister of State for Education. These debates remain topical and instructive.

Powered two-wheelers road accidents and their risk perception in dense urban areas: case of Paris.

For a few years, the use of powered two-wheelers has taken off in Paris. It then became critical for the City of Paris to understand both the mechanisms leading to traffic accidents involving at least one powered two-wheelers user and the perception of their risk when riding in dense urban areas. In so doing, two studies were carried out along similar lines so that their results could be compared. The first study focused on the perception of situations where accidents are most likely to occur. The second one was an analysis of police reports of accidents involving at least one powered two-wheelers and the drawing-up of prototypical accident scenarios. Comparing the results of the two studies revealed a gap between perceived and objective risks of these users. In fact, they rather fear the situations during which a car driver is changing lanes, while accidents involving them occur more often when a car driver turns (right, left or U). Knowledge of this dissonance in terms of awareness of road risks for powered two-wheelers and equally, other road users, will give the City of Paris food for thought. The promising results of this study have encouraged the City of Paris to extend it to other types of users, such as cyclists or elderly pedestrians. Copyright © 2011 Elsevier Ltd.

From Paris to Iowa and Back: Global Temperature Targets, Agricultural Impacts, and Producer Response

Traditionally, assessments such as those produced by IPCC and USGCRP have been structured to provide a one-way flow of information from scientists to national and international policy makers. Because the Paris Agreement will ultimately require corresponding domestic policies, the traditional one-way information flow could be inadequate, since it lacks both direct participation and informed feedback from many of the important entities that influence domestic policy. We have engaged Iowa row crop producers in identifying impacts and feasibility of adaptation under global warming of 1.0 and 2.0OC. Our engagement seeks to create within climate impacts assessment a decision-maker feedback loop. We have engaged an expert panel by using yield data modeling as a first step to communicate vividly the potential yield impacts of global average temperature targets. This engagement included validation with historical global average temperature before presenting yield impact under global mean surface temperature increase of 1.0 and 2.0OC. The expert panel requested further analysis of targets at 0.25 and 0.50OC increase and of possible impacts should they pursue adaptation by increasing maize plant population density and soil moisture storage. Several clear messages have emerged that can be voiced by Iowa agribusiness leaders to national and international decision-makers. While Iowa soybean agriculture may remain robust for the foreseeable future, the Paris Agreement is insufficient to protect Iowa maize production from substantial changes in productivity and volatility. These effects could be largely (though not entirely) mitigated by moving from the current +2OC to the "high ambition" +1.5OC target. The projected spring rainfall increase of 10% under +1OC would increase the cost of spring planting. The data model predicts a 5-day reduction in average number of fieldwork days, which requires the addition of one half-time person or larger planting equipment. The current annual

Importance of the pre-industrial baseline for likelihood of exceeding Paris goals

During the Paris conference in 2015, nations of the world strengthened the United Nations Framework Convention on Climate Change by agreeing to holding `the increase in the global average temperature to well below 2 °C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5 °C' (ref. ). However, `pre-industrial' was not defined. Here we investigate the implications of different choices of the pre-industrial baseline on the likelihood of exceeding these two temperature thresholds. We find that for the strongest mitigation scenario RCP2.6 and a medium scenario RCP4.5, the probability of exceeding the thresholds and timing of exceedance is highly dependent on the pre-industrial baseline; for example, the probability of crossing 1.5 °C by the end of the century under RCP2.6 varies from 61% to 88% depending on how the baseline is defined. In contrast, in the scenario with no mitigation, RCP8.5, both thresholds will almost certainly be exceeded by the middle of the century with the definition of the pre-industrial baseline of less importance. Allowable carbon emissions for threshold stabilization are similarly highly dependent on the pre-industrial baseline. For stabilization at 2 °C, allowable emissions decrease by as much as 40% when earlier than nineteenth-century climates are considered as a baseline.

Recent technical developments using the large volume Paris-Edinburgh press platform have enabled x-ray synchrotron studies at high pressure and temperature conditions. However, its application to some materials of interest, such as high hazard materials that require special handling due to safety issues, reactivity, or other challenges, has not been feasible without the introduction of special containment systems to eliminate the hazards. However, introduction of a containment system is challenging due to the requirement to provide full safety containment for operation in the variety of environments available, while not hindering any of the experimental probes that are available for inert samplemore » measurement.

With the development of information and communication technologies, telemedicine has been proposed as a way to improve patient management by facilitating access to appropriate diagnosis and treatment. The Paris Ile de France Regional Health Agency is currently funding a comprehensive program of telemedicine experiments. This article describes the protocols for the evaluation of the implementation of telemedicine in the Paris region. Over 2,500 patients have been included in eight studies addressing the use of telemedicine in the context of specific diseases or settings. Two projects are randomized controlled trials, while the six other projects are based on before-after designs (differences in differences studies). Based on the MAST model and the French national framework, we identified endpoints to assess the impact of telemedicine on five dimensions: clinical effectiveness, cost-effectiveness, security of the application, patient satisfaction and quality of life and perception of professionals. Telemedicine encompasses a wide range of services and stakeholders, and thus study protocols must be tailored to the specific constraints and interests of the users.

To compare the associations between food environment at the individual level, socioeconomic status (SES) and obesity rates in two cities: Seattle and Paris. Analyses of the SOS (Seattle Obesity Study) were based on a representative sample of 1340 adults in metropolitan Seattle and King County. The RECORD (Residential Environment and Coronary Heart Disease) cohort analyses were based on 7131 adults in central Paris and suburbs. Data on sociodemographics, health and weight were obtained from a telephone survey (SOS) and from in-person interviews (RECORD). Both studies collected data on and geocoded home addresses and food shopping locations. Both studies calculated GIS (Geographic Information System) network distances between home and the supermarket that study respondents listed as their primary food source. Supermarkets were further stratified into three categories by price. Modified Poisson regression models were used to test the associations among food environment variables, SES and obesity. Physical distance to supermarkets was unrelated to obesity risk. By contrast, lower education and incomes, lower surrounding property values and shopping at lower-cost stores were consistently associated with higher obesity risk. Lower SES was linked to higher obesity risk in both Paris and Seattle, despite differences in urban form, the food environments and in the respective systems of health care. Cross-country comparisons can provide new insights into the social determinants of weight and health.

Airborne pollution in dense urban areas is nowadays a subject of major concern. Fine particulate pollution events are ever more frequent and represent not only an environmental and health but also a real economic issue. In urban atmosphere, the so-called PM2.5 (particulate matter < 2.5 μm in diameter) and ultrafine fractions (< 100 nm) due to combustion, causes many adverse health effects. Environmental magnetic studies of airborne PM collected on air filters or plants have demonstrated their potential to follow the metallic pollution and determine their sources (Sagnotti et al., 2012). In this study, we report on magnetic measurements of traffic-related airborne PM in the city of Paris, France. Two distinct environments were sampled and analyzed along the Seine River: the aquatic environment in studying fluvial bank and river bed sediments and the atmospheric environment by regarding magnetic particles trapped in adjacent tree barks (Platanus hispanica). About 50 sediment samples and 350 bark samples have been collected and analysed to determine their magnetic properties (susceptibility, hysteresis parameters, IRM, frequency-dependent susceptibility) and to estimate the presence and spatial concentration of superparamagnetic or multi-domain particles for each sample type. The bark results allow proposing a high spatial resolution mapping (< 50 m) of magnetic susceptibility and frequency dependent susceptibility on a 30 km long profile along the river. Variations in that profile may be linked to the atmospheric metallic pollution. In addition to that, the sampling of banks and riverbed sediments of the Seine allow a global estimation on the anthropogenic versus detrital and biologic input in the city of Paris. The first results presented here show a general increase of the concentration in magnetic particles from upstream to downstream Paris probably linked to urban pollutions as previously observed for suspended particulate matter (Franke et al. 2009; Kayvantash

Paris suggests that some cultures provide protective factors that can suppress the emergence of borderline personality disorder (BPD). Yet all cultures contain some individuals who perceive themselves as unable to meet what is expected of them, and the resultant distress is expressed through a variety of "ethnic" disorders such as susto or nervios. When viewed in this context, BPD is similar to these disorders, notably in the perceived sense of social failure, marginality and powerlessness.

Carroy, Jacqueline; Schmidgen, Henning

2004-01-01

This article diiscusses from a comparative perspective the complex history of the reaction experiment with the Hipp chronoscope, one of the central experiments of late 19th-century psychology. It focuses on Wilhelm Wundt's (1832-1920) Institute for Experimental Psychology in Leipzig and on the Paris Laboratory for Physiological Psychology at the Sorbonne, which was initially directed by Henry Beaunis (1830-1921), but soon came to be dominated by the research activities of Alfred Binet (1857-1911). When the Paris psychologists founded their Laboratory in 1889, they took the Leipzig Institute as their model. In the early 1890s they adopted the reaction time experiment that had been central to Wundt's psychology. Shortly after, they modified this experiment according to their own specific interests. For Binet, it no longer served as a method for identifying the elementary components of "general" consciousness (as in Wundt), but for classifying "individual" personalities. The methodological and technological changes that Binet introduced into the experimental practice of psychology had no immediate impact on the research work in Leipzig. However, they influenced the "Wurzburg School" of psychology under Wundt's former assistant, Oswald Külpe (1862-1915). This illustrates that the comparative history of transfers of "experimental systems" (Rheinberger) across national borders is not simply a history of mere transports. Rather, it is a history of transferences that sometimes includes surprising "re-transferences".

By the revolution of 1789, the four-story, quadrangular Palais Royal in Paris had become the most glittering tourist center of Europe, with 180 shops and cafes in its ground floor arcades. By 1791, its basement and secondary story contained over 100 separate, illicit gambling operations featuring the most popular dice and card games. The mania for gambling had been transferred from defunct, monarchical Versailles to the thriving, bourgeois Palais Royal, where the five main gaming clubs throbbed from noon till midnight. During the Revolution, Prince Talleyrand won 30,000 francs at one club, and after Waterloo in 1815, Marshal Blucher lost 1,500,000 francs in one night at another. To bring the situation under control and raise taxes for the state, in 1806 Napoleon legalized the main clubs, which from 1819 to 1837 grossed an enormous 137 million francs. When the anti-gambling forces triumphed in 1837 and the clubs were closed down, the National Guard had to be called out to evict the mobs of gamblers who refused to leave the tables. Dramatic reports from Revolutionary police raids, and quotations from the memoirs of humorous French gamblers and shocked foreign visitors, provide anecdotal illustrations of the 49 years during which the Palais Royal was the most intriguing and picturesque gambling mecca of Europe-and probably of the world.

A diverse set of photometric, astrometric, spectral and surface brightness data exist on decades of photographic glass plates. The Astronomical Photographic Data Archive (APDA) at the Pisgah Astronomical Research Institute (PARI) was established in November 2007 and is dedicated to the task of collecting, restoring, preserving and storing astronomical photographic data and PARI continues to accept collections. APDA is also tasked with scanning each image and establishing a database of images that can be accessed via the Internet by the global community of scientists, researchers and students. APDA is a new type of astronomical observatory - one that harnesses analog data of the night sky taken for more than a century and making that data available in a digital format.In 2016, APDA expanded from 50 collections with about 220,000 plates to more than 55 collections and more than 340,000 plates and films. These account for more than 30% of all astronomical photographic data in the United States. The largest of the new acquisitions are the astronomical photographic plates in the Yale University collection. We present details of the newly added collections and review of other collections in APDA.

Poverty, gender and incarceration in sixteenth-century Paris.

The experience of prison remains a relatively little-studied aspect of late-medieval and early-modern criminalization of the activities of the poor. This study examines how poverty and gender influenced incarceration practices, treatment and release in sixteenth-century Paris. A study of the archives of the ecclesiastical gaol at Saint-Germain-des-Prés from 1537 to 1579 suggests that both poverty and gender affected the crimes for which women and men were imprisoned, the length of time they remained in detention and the reasons for their release.

What would it take to achieve the Paris temperature targets?

Here, the 2015 Paris Agreement aims to limit warming to 2 or 1.5°C above preindustrial level, although combined Intended Nationally Determined Contributions (INDCs) are likely insufficient to achieve these targets. We propose a set of idealized emission pathways consistent with the targets. If countries reduce emissions in line with their INDCs, the 2°C threshold could be avoided only if net zero greenhouse gas emissions (GHGEs) are achieved by 2085 and late century negative emissions are considerably in excess of those assumed in Representative Concentration Pathway (RCP) 2.6 (net –5 Gt CO 2/yr, compared with –1.5 Gt CO 2/yr in RCP2.6).more » More aggressive near-term reductions would allow 2°C to be avoided with less end-of-century carbon removal capacity. A 10% cut in GHGEs by 2030 (relative to 2015) could likely achieve 2°C with RCP2.6 level negative emissions. The 1.5°C target requires GHGEs to be reduced by almost a third by 2030 and net zero by 2050, while a 50 year overshoot of 1.5°C allows net zero GHGEs by 2060.« less

Recent technical developments using the large volume Paris-Edinburgh press platform have enabled x-ray synchrotron studies at high pressure and temperature conditions. However, its application to some materials of interest, such as high hazard materials that require special handling due to safety issues, reactivity, or other challenges, has not been feasible without the introduction of special containment systems to eliminate the hazards. However, introduction of a containment system is challenging due to the requirement to provide full safety containment for operation in the variety of environments available, while not hindering any of the experimental probes that are available for inert samplemore » measurement. In this work, we report on the development and implementation of a full safety enclosure for a Paris-Edinburgh type press. During the initial development and subsequent application stage of work, experiments were performed on both cerium dioxide (CeO2) and uranium (U). As a result, this device allows for full implementation of all currently available experimental probes involving the Paris-Edinburgh press at the High Pressure Collaborative Access Team sector of the Advanced Photon Source.« less

The 4th Biennial Meeting of the Human Variome Project Consortium was held at the headquarters of the United Nations Educational, Scientific and Cultural Organization (UNESCO) in Paris, 11-15 June 2012. The Human Variome Project, a nongovernmental organization and an official partner of UNESCO, enables the routine collection, curation, interpretation, and sharing of information on all human genetic variation. This meeting was attended by more than 180 delegates from 39 countries and continued the theme of addressing issues of implementation in this unique project. The meeting was structured around the four main themes of the Human Variome Project strategic plan, "Project Roadmap 2012-2016": setting normative function, behaving ethically, sharing knowledge, and building capacity. During the meeting, the members held extensive discussions to formulate an action plan in the key areas of the Human Variome Project. The actions agreed on were promulgated at the Project's two Advisory Council and Scientific Advisory Committee postconference meetings.

Climate change and heat waves in Paris and London metropolitan areas

NASA Astrophysics Data System (ADS)

Dousset, B.

2010-12-01

Summer warming trends in Western and Central Europe and in Mediterranean regions are increasing the incidence, intensity, and duration of heat waves. Those extreme events are especially deadly in large cities, owing to high population densities, surface characteristics, heat island effects, anthropogenic heat and pollutants. In August 2003, a persistent anticyclone over Western Europe generated a heat wave of exceptional strength and duration with an estimated death toll of 70,000, including 4678 in the Paris region. A series of NOAA-AVHRR satellite thermal images over the Paris and London metropolitan areas, were used to analyze Land Surface Temperature (LST) and its related mortality. In the Paris region, LSTs were merged with land use and cover data to identify risk areas, and thermal indicators were produced at the addresses of ~ 500 elderly people to assess diurnal heat exposure. Results indicate: (i) contrasting night time and daytime heat island patterns related to land use and surface characteristics; (ii) the relation between night-time heat islands and heat waves intensity; (iii) the impact of elevated minimal temperatures on excess mortality, with a 0.5 °C increase doubling the risk of death, (in the temperature range of the heatwave); iv) the correlation between the spatial distribution of highest night-time LSTs and that of highest mortality ratios; and v) the significant impact of urban parks in the partitioning between latent and sensible surface heat fluxes, despite a prior warm and dry spring. Near-real time satellite monitoring of heat waves in urban areas improve our understanding of the LST processes and spatial variability, and of the related heat stress and mortality. These observations provide criteria for warning systems, contingency policies and planning, and climate adaptation and mitigation strategies.

This study presents results from the specific large-eddy simulation study of the urban boundary layer in the MEGAPOLI Paris Plume field campaign. We used LESNIC and PALM codes, MEGAPOLI city morphology database, nudging to the observed meteorological conditions during the Paris Plume campaign and some concentration measurements from that campaign to simulate and better understand the nature of the urban boundary layer on scales larger then the street canyon scales. The primary attention was paid to turbulence self-organization and structure-to-surface interaction. The study has been aimed to demonstrate feasibility and estimate required resources for such research. Therefore, at this stage we do not compare the simulation with other relevant studies as well as we do not formulate the theoretical conclusions.

What Does It Mean to be Central? A Botanical Geography of Paris 1830-1848.

PubMed

Hoquet, Thierry

2016-02-01

This paper focuses on the geography of the botanical community in Paris, under the July Monarchy (1830-1848). At that time, the Muséum d'Histoire naturelle (MHN) was at its institutional acme and, under the impulse of François Guizot, its budget was increasing dramatically. However, closer attention to manuscript sources (correspondence, travel diaries) reveals that the botanists of the time favoured other private institutions, located both on the Right and Left Banks of the Seine. The MHN was prestigious for its collections and professors but it was relatively remote from the centre of Paris, and its plant samples were sometimes difficult to access. Several other first-class private herbaria granted liberal access to botanists: those of Jacques Gay, Phillip Barker Webb, and Benjamin Delessert. Thanks to their wealth, these plant amateurs had ownership of historical herbaria consisting of species types alongside rich botanical libraries. Botanists visiting Paris from foreign countries or other provinces of France also spent some time studying less general plant collections, like those of Count Jaubert, or specialized collections, like Montagne's or Léveillé's on cryptogams. Other botanists also enjoyed renown at the time, although they published little, if anything (like Maire). Living in crammed apartments, literally in the middle of their plant samples, these botanists were key nodes in botanical networks, although they had no relation with the prestigious MHN.

Objective To compare the associations between food environment at the individual level, socioeconomic status (SES) and obesity rates in two cities: Seattle and Paris. Methods Analyses of the SOS (Seattle Obesity Study) were based on a representative sample of 1340 adults in metropolitan Seattle and King County. The RECORD (Residential Environment and Coronary Heart Disease) cohort analyses were based on 7,131 adults in central Paris and suburbs. Data on socio-demographics, health and weight were obtained from a telephone survey (SOS) and from in-person interviews (RECORD). Both studies collected data on and geocoded home addresses and food shopping locations. Both studies calculated GIS network distances between home and the supermarket that study respondents listed as their primary food source. Supermarkets were further stratified into three categories by price. Modified Poisson regression models were used to test the associations among food environment variables, SES and obesity. Results Physical distance to supermarkets was unrelated to obesity risk. By contrast, lower education and incomes, lower surrounding property values, and shopping at lower-cost stores were consistently associated with higher obesity risk. Conclusion Lower SES was linked to higher obesity risk in both Paris and Seattle, despite differences in urban form, the food environments, and in the respective systems of health care. Cross-country comparisons can provide new insights into the social determinants of weight and health. PMID:23736365

The number of families living in shelters in the Paris region (France) has increased by a factor of three in 10 years. In 2013, a survey was performed on homeless families in order to characterize their living conditions, their health needs, and the developmental problems in children. This probability survey was conducted in 17 languages among 801 homeless families sheltered in emergency centers for asylum-seekers, emergency housing centers, social rehabilitation centers, and social hotels in the Paris region. Among the 772 families that provided data on food security only 14.0% were with food security, whereas 43.3% were with low food security and 9.8% with very low food security (a situation where children are also affected). Stratified multivariate robust Poisson models showed that some characteristics are associated with a higher risk of food insecurity and/or of falling into very low food security, such as residential instability, single parenthood, having more than three children, depressive symptoms, housing in social hostels, and difficult access to cheap or free food locally. Given the wealth of the Paris region, resources and programs should be concentrated on improving the living situation of this vulnerable population. It needs better detection of these families, a closer social follow-up, and an increase in food aid. PMID:29495563

Sudden cardiac death is an unexpected cardiac arrest without obvious extra-cardiac cause. Epidemiology of sudden cardiac death has been poorly documented in France, mainly because of challenging requirement in order to capture all cases in a specific area. The Parisian registry (Sudden Death Expertise Center, European Georges Pompidou Hospital, Paris) was initiated in May 2011 and analyzed data of all sudden death in Paris and suburbs (6.6 millions inhabitants). Over 3 years, the annual incidence estimated to 50-70 per 100,000. Those occurred mainly in men (69%), with a mean age of 65 year, and at home (75%). The event was witnessed in 80% of cases, but bystander cardiopulmonary resuscitation was initiated in only half of cases. Initial cardiac rhythm was ventricular fibrillation in 25%. Survival to hospital discharge remains low (8%).

The pre-exposure prophylaxis (PrEP) drug Truvada is a new HIV prevention technology that is predominantly promoted as relevant to HIV-negative gay men. This paper explores what PrEP represents for HIV-positive gay men living in Paris, based upon data collected through interviews and ethnographic research. While HIV-positive gay men do not directly consume Truvada through PrEP, they nonetheless hold opinions and understandings of this drug, specifically as it relates to their own sexuality. This paper expands the representations and meanings of this new technology in a different light through the voices of gay men living with HIV in Paris. The main argument of this article is that PrEP as an additional HIV prevention tool blurs the lines between science, technologies and human sexuality.

Importance of the Pre-Industrial Baseline in Determining the Likelihood of Exceeding the Paris Limits

During the Paris Conference in 2015, nations of the world strengthened the United NationsFramework Convention on Climate Change by agreeing to holding "the increase in the globalaverage temperature to well below 2°C above pre-industrial levels and pursuing efforts to limitthe temperature increase to 1.5°C. However, "pre-industrial" was not defined. Here weinvestigate the implications of different choices of the pre-industrial baseline on the likelihood ofexceeding these two temperature thresholds. We find that for the strongest mitigation scenarioRCP2.6 and a medium scenario RCP4.5 the probability of exceeding the thresholds and timingof exceedance is highly dependent on the pre-industrial baseline, for example the probability ofcrossing 1.5°C by the end of the century under RCP2.6, varies from 61% to 88% depending onhow the baseline is defined. In contrast, in the scenario with no mitigation, RCP8.5, boththresholds will almost certainly be exceeded by the middle of the century with the definition ofthe pre-industrial baseline of less importance. Allowable carbon emissions for thresholdstabilisation are similarly highly dependent on the pre-industrial baseline. For stabilisation at2°C, allowable emissions decrease by as much as 40% when earlier than 19th century climatesare considered as a baseline.

Paris vs. Murchison: Impact of hydrothermal alteration on organic matter in CM chondrites

Unravelling the origin of organic compounds that were accreted into asteroids requires better constraining the impact of asteroidal hydrothermal alteration on their isotopic signatures, molecular structures, and spatial distribution. Here, we conducted a multi-scale/multi-technique comparative study of the organic matter (OM) from two CM chondrites (that originate from the same parent body or from identical parent bodies that accreted the same mixture of precursors) and underwent a different degree of hydrothermal alteration: Paris (a weakly altered CM chondrite - CM 2.8) and Murchison (a more altered one - CM 2.5). The Paris insoluble organic matter (IOM) shows a higher aliphatic/aromatic carbon ratio, a higher radical abundance and a lower oxygen content than the Murchison IOM. Analysis of the OM in situ shows that two texturally distinct populations of organic compounds are present within the Paris matrix: sub-micrometric individual OM particles and diffuse OM finely distributed within phyllosilicates and amorphous silicates. These results indicate that hydrothermal alteration on the CM parent body induced aromatization and oxidation of the IOM, as well as a decrease in radical and nitrogen contents. Some of these observations were also reported by studies of variably altered fragment of Tagish Lake (C2), although the hydrothermal alteration of the OM in Tagish Lake was apparently much more severe. Finally, comparison with data available in the literature suggests that the parent bodies of other chondrite petrologic groups could have accreted a mixture of organic precursors different from that accreted by the parent body of CMs.

Heat-waves have a substantial public health burden. Understanding spatial heterogeneity at a fine spatial scale in relation to heat and related mortality is central to target interventions towards vulnerable communities. To determine the spatial variability of heat-wave-related mortality risk among elderly in Paris, France at the census block level. We also aimed to assess area-level social and environmental determinants of high mortality risk within Paris. We used daily mortality data from 2004 to 2009 among people aged >65 at the French census block level within Paris. We used two heat wave days' definitions that were compared to non-heat wave days. A Bernoulli cluster analysis method was applied to identify high risk clusters of mortality during heat waves. We performed random effects meta-regression analyses to investigate factors associated with the magnitude of the mortality risk. The spatial approach revealed a spatial aggregation of death cases during heat wave days. We found that small scale chronic PM 10 exposure was associated with a 0.02 (95% CI: 0.001; 0.045) increase of the risk of dying during a heat wave episode. We also found a positive association with the percentage of foreigners and the percentage of labor force, while the proportion of elderly people living in the neighborhood was negatively associated. We also found that green space density had a protective effect and inversely that the density of constructed feature increased the risk of dying during a heat wave episode. We showed that a spatial variation in terms of heat-related vulnerability exists within Paris and that it can be explained by some contextual factors. This study can be useful for designing interventions targeting more vulnerable areas and reduce the burden of heat waves. Copyright © 2017 Elsevier B.V. All rights reserved.

Alkylphenolic compounds and bisphenol A contamination within a heavily urbanized area: case study of Paris.

This study evaluates the influence of a heavily urbanized area (Paris Metropolitan area), on receiving water contamination by both bisphenol A (BPA) and alkylphenol ethoxylate (APE) biodegradation product. The study began by investigating concentrations within urban sources. In addition to the more commonly studied wastewater treatment plant effluent, wet weather urban sources (including combined sewer overflows, urban runoff, and total atmospheric fallout) were considered. The initial results highlight a significant contamination of all urban sources (from a few nanograms per liter in atmospheric fallout to several micrograms per liter in the other sources) with clearly distinguishable distribution patterns. Secondly, concentration changes along the Seine River from upstream of the Paris Metropolitan area to downstream were investigated. While the concentrations of BPA and nonylphenoxy acetic acid (NP₁EC) increase substantially due to urban sources, the 4-nonylphenol concentrations remain homogeneous along the Seine. These results suggest a broad dissemination of 4-nonylphenol at the scale of the Seine River basin. Moreover, the relationship between pollutant concentrations and Seine River flow was assessed both upstream and downstream of the Paris conurbation. Consequently, a sharp decrease in dissolved NP1EC concentrations relative to Seine River flow underscores the influence of single-point urban pollution on Seine River contamination. Conversely, dissolved 4-nonylphenol concentrations serve to reinforce the hypothesis of its widespread presence at the Seine River basin scale.

How did the Parisian rescue system respond and how did it evolve since?We proved we could deploy quickly wide prehospital and hospital resources and teams' equipment and preparedness is being further developed. To secure a swifter initial response, we need a better integration of the operators of the rescue chain with a simpler and more robust organization as well as improved communications channels. We must continue to anticipate and prepare for possible future attacks.

Australia's Unprecedented Future Temperature Extremes Under Paris Limits to Warming

NASA Astrophysics Data System (ADS)

Lewis, Sophie C.; King, Andrew D.; Mitchell, Daniel M.

2017-10-01

Record-breaking temperatures can detrimentally impact ecosystems, infrastructure, and human health. Previous studies show that climate change has influenced some observed extremes, which are expected to become more frequent under enhanced future warming. Understanding the magnitude, as a well as frequency, of such future extremes is critical for limiting detrimental impacts. We focus on temperature changes in Australian regions, including over a major coral reef-building area, and assess the potential magnitude of future extreme temperatures under Paris Agreement global warming targets (1.5°C and 2°C). Under these limits to global mean warming, we determine a set of projected high-magnitude unprecedented Australian temperature extremes. These include extremes unexpected based on observational temperatures, including current record-breaking events. For example, while the difference in global-average warming during the hottest Australian summer and the 2°C Paris target is 1.1°C, extremes of 2.4°C above the observed summer record are simulated. This example represents a more than doubling of the magnitude of extremes, compared with global mean change, and such temperatures are unexpected based on the observed record alone. Projected extremes do not necessarily scale linearly with mean global warming, and this effect demonstrates the significant potential benefits of limiting warming to 1.5°C, compared to 2°C or warmer.

Overweight according to geographical origin and time spent in France: a cross sectional study in the Paris metropolitan area

PubMed Central

2012-01-01

Background For the first time in France in a population-based survey, this study sought to investigate the potential impact of migration origin and the proportion of lifetime spent in mainland France on body mass index (BMI) and overweight in adults living in the Paris metropolitan area. Methods A representative, population-based, random sample of the adult, French speaking population of the Paris metropolitan area was interviewed in 2005. Self-reported BMI (BMI = weight/height2) and overweight (BMI ≥ 25) were our 2 outcomes of interest. Two variables were constructed to estimate individuals’ migration origin: parental nationality and the proportion of lifetime spent in mainland France, as declared by the participants. We performed multilevel regression models among different gender and age groups, adjusted for demographics and socioeconomic status. Results In women, a parental origin in the Middle East or North Africa (MENA) was associated with a higher risk of being overweight (especially before the age of 55) and a higher BMI (between 35 and 54 years of age), and so were women of Sub-Sahara African parental origin in the middle age category. Only in the youngest men (< 35 years of age) did we observe any association with parental nationality, with a higher BMI when having a MENA parentage. Regarding the association between the proportion of lifetime spent in France and overweight, we observed that, in women, a proportion of 50% to 99% appeared to be associated with overweight, especially after the age of 35.

The aim of the study was to investigate the value of microscopic findings in the classification of pediatric Crohn disease (CD) by determining whether classification of disease changes significantly with inclusion of histologic findings. Sixty patients were randomly selected from a cohort of patients studied at the Pediatric Inflammatory Bowel Disease Clinic at the University of California, San Francisco Benioff Children's Hospital. Two physicians independently reviewed the electronic health records of the included patients to determine the Paris classification for each patient by adhering to present guidelines and then by including microscopic findings. Macroscopic and combined disease location classifications were discordant in 34 (56.6%), with no statistically significant differences between groups. Interobserver agreement was higher in the combined classification (κ = 0.73, 95% confidence interval 0.65-0.82) as opposed to when classification was limited to macroscopic findings (κ = 0.53, 95% confidence interval 0.40-0.58). When evaluating the proximal upper gastrointestinal tract (Paris L4a), the interobserver agreement was better in macroscopic compared with the combined classification. Disease extent classifications differed significantly when comparing isolated macroscopic findings (Paris classification) with the combined scheme that included microscopy. Further studies are needed to determine which scheme provides more accurate representation of disease extent.

Calculations of antiproton-nucleus quasi-bound states using the Paris N bar N potential

2018-01-01

An optical potential constructed using the p bar N scattering amplitudes derived from the 2009 version of the Paris N bar N potential is applied in calculations of p bar quasi-bound states in selected nuclei across the periodic table. A proper self-consistent procedure for treating energy dependence of the amplitudes in a nucleus appears crucial for evaluating p bar binding energies and widths. Particular attention is paid to the role of P-wave amplitudes. While the P-wave potential nearly does not affect calculated p bar binding energies, it reduces considerably the corresponding widths. The Paris S-wave potential supplemented by a phenomenological P-wave term yields in dynamical calculations p bar binding energies Bpbar ≈ 200 MeV and widths Γpbar ∼ 200- 230 MeV, which is very close to the values obtained within the RMF model consistent with p bar -atom data.

A rapid method was developed and validated by ultra-performance liquid chromatography-triple quadrupole mass spectroscopy with ultraviolet detection (UPLC-UV-MS) for simultaneous determination of paris saponin I, paris saponin II, paris saponin VI and paris saponin VII. Partial least squares discriminant analysis (PLS-DA) based on UPLC and Fourier transform infrared (FT-IR) spectroscopy was employed to evaluate Paris polyphylla var. yunnanensis (PPY) at different harvesting times. Quantitative determination implied that the various contents of bioactive compounds with different harvesting times may lead to different pharmacological effects; the average content of total saponins for PPY harvested at 8 years was higher than that from other samples. The PLS-DA of FT-IR spectra had a better performance than that of UPLC for discrimination of PPY from different harvesting times. Copyright © 2016 John Wiley & Sons, Ltd.

Secondary pollutants such as ozone, secondary inorganic aerosol, and secondary organic aerosol formed in the plumes of megacities can affect regional air quality. In the framework of the FP7/EU MEGAPOLI (Megacities: Emissions, urban, regional and Global Atmospheric POLlution and climate effects, and Integrated tools for assessment and mitigation) project, an intensive campaign was launched in the greater Paris region in July 2009. The major objective was to quantify different sources of organic aerosol (OA) within a megacity and in its plume. In this study, we use airborne measurements aboard the French ATR-42 aircraft to evaluate the regional chemistry-transport model CHIMERE within and downwind of the Paris region. Two mechanisms of secondary OA (SOA) formation are used, both including SOA formation from oxidation and chemical aging of primary semivolatile and intermediate volatility organic compounds (SI-SOA) in the volatility basis set (VBS) framework. As for SOA formed from traditional VOC (volatile organic compound) precursors (traditional SOA), one applies chemical aging in the VBS framework adopting different SOA yields for high- and low-NOx environments, while another applies a single-step oxidation scheme without chemical aging. Two emission inventories are used for discussion of emission uncertainties. The slopes of the airborne OA levels versus Ox (i.e., O3 + NO2) show SOA formation normalized with respect to photochemical activity and are used for specific evaluation of the OA scheme in the model. The simulated slopes were overestimated slightly by factors of 1.1, 1.7 and 1.3 with respect to those observed for the three airborne measurements, when the most realistic "high-NOx" yields for traditional SOA formation in the VBS scheme are used in the model. In addition, these slopes are relatively stable from one day to another, which suggests that they are characteristic for the given megacity plume environment. The configuration with increased primary

The present study is to compare specific chromatograms and main acitive components between wild and cultivated rhizomes of Paris polyphylla var. yunnanensis by HPLC. HPLC analysis was performed on a Waters XSelect HSS T3 C₁₈ clumn (4.6 mm×250 mm, 5 μm), with a mobile phase consisting of acetonitrile (A)-water (B) at a flow rate of 1 mL•min⁻¹ (0-50 min,30%-50%A;50-80 min,50% A,80-85 min,50%-30%A;85-100 min,30% A). The detection wavelength was 203 nm and the column temperature was controlled at 30 ℃, and the injection volume was 10 μL. HPLC specific chromatograms of wild and cultivated rhizomes of P. polyphylla var. yunnanensis were established and nine steroidal saponins were simultaneously determined by the above method. The mean contents of paris saponin Ⅶ, paris saponin H and total average contents of four pennogenyl saponins in Rhizomes of wild samples were significantly higher than those of cultivated ones. However, this result is opposite from the average content of paris saponin Ⅰ and total average contents of five dioscins in the wild and cultivated samples. Because the significant differences occurred for the specific chromatograms and main active components between the wild and cultivated P. polyphylla var. yunnanensis, much more pharmacological and clinical researches are therefore necessary.

Over the past 20 years, rules concerning wastewater treatment and quality of water discharged into the environment have changed considerably. Huge investments have been made in Paris conurbation to improve waste water treatment processes in accordance with the European Water Framework Directive. The interdepartmental association for sewage disposal in Paris conurbation (SIAAP) carried out a monitoring of both fish assemblages and water quality in the Seine River around the Paris conurbation (France) since the early 90's. The main goal of this study was to estimate the influence of the water quality improvement on fish. On one hand, the study confirmed the improvement of the water quality (dissolved oxygen, ammonia nitrogen, organic matter) in the Seine River, mostly focused downstream of Paris conurbation. On the other hand, an increase of the number of species occurred from 1990 (14) to 2013 (21). Moreover, changes in the river Seine assemblages happened over that 23-year period with emergence of sensitive species (ruffe, scalpin and pike-perch). The improvement of the water quality was also reported with respect to the Index of Biotic Integrity (IBI). However, no variation of pollutant concentrations in roach, eel and chub muscles has been observed. An exceedance of the environmental quality standards have even been reported all over this period as regards mercury and organochlorine.

The pillar of metropolitan greatness: The long making of archeological objects in Paris (1711-2001).

Over three centuries after the 1711 discovery in the choir of Notre-Dame in Paris of a square-section stone bas-relief (the Pillar of the Boatmen) with depictions of several deities, both Gaulish and Roman, the blocks comprising it were analyzed as a symbol of Parisian power, if not autonomy, vis-à-vis the Roman Empire. Variously considered as local, national, or imperial representations, the blocks were a constant object of admiration, interrogation, and speculation among antiquarians of the Republic of Letters. They were also boundary objects - products of the emergence of a Parisian archeology dated from 1711. If this science reflected the tensions and ambiguities of a local regime of knowledge situated in a national context, it also helped to coordinate archeological work between different institutions and actors. This paper would like to assess the specific role played by the Pillar of the Boatmen as a fetish object in this process. To what extent could an archeological artifact influence this reshaping of urban representation, this change of scales? By following the three-century career of the pillar's blocks as composite objects, which some have identified as merely stones or a column, it is possible to understand the multiple dimensions that defined the object as archeological - as an artifact that contributed to the relocating of the historical city center - and the multiple approaches that transform existing remains into knowledgeable objects.

Trading-off emission reduction, carbon capture and geoengineering to reach the Paris agreement

We explore virtually all possible future pathways that respect the Paris agreement, with an innovative modeling framework. We show that immediate and extreme mitigation of CO2 and non-CO2 species alike, carbon dioxide removal (CDR) and/or solar radiation management (SRM) technologies are required. We analyze the tradeoffs between these solutions. We generate thousands of temperature change pathways that extend historical records, stay below 2°C, and aim at 1.5°C in the long run. Non-CO2 forcings are generated likewise. With a simple model of the Earth system, we then back-calculate anthropogenic CO2 emissions compatible with these pathways. Other key global variables such as ocean acidity, sea level and permafrost thaw are also simulated. From this large ensemble of fully consistent scenarios, we analyze subsets that meet certain criteria: physical targets, emission levels, technology use, or any combination thereof. We show that staying below 1.5°C is feasible if CO2 emissions peak before 2025 and non-CO2 forcings are also reduced to zero. In case of a positive long-term non-CO2 forcing (a mitigation floor), CDR is necessary. Alternatively, emissions can peak later and/or higher if SRM is allowed. For pathways overshooting 1.5°C, results depend on the overshoot's size and length. Because of thawing permafrost, virtually all overshoot pathways require CDR, unless non-CO2 species (possibly SRM) are cooling the system at the time of peak temperature. When considering additional physical targets, which can be relevant for preserving ecosystems, the space of allowable pathways is systematically reduced. Especially: limiting ocean acidification rules out SRM. The nationally determined contributions (NDCs) indicate that reaching even the strictest interpretation of the agreement is feasible. However, if SRM is ruled out and only a reasonable amount of CDR is allowed, NDCs are compatible with very few of our pathways (≈5%). If a mitigation floor is added on top of

Time series studies assessing the effect of temperature on mortality generally use temperatures measured by a single weather station. In the Paris region, there is a substantial measurement network, and a variety of exposure indicators created from multiple stations can be tested. The aim of this study is to test the influence of exposure indicators on the temperature-mortality relationship in the Paris region. The relationship between temperature and non-accidental mortality was assessed based on a time series analysis using Poisson regression and a generalised additive model. Twenty-five stations in Paris and its three neighbouring departments were used to create four exposure indicators. These indicators were (1) the temperature recorded by one reference station, (2) a simple average of the temperatures of all stations, (3) an average weighted on the departmental population and (4) a classification of the stations based on land use and an average weighted on the population in each class. The relative risks and the Akaike criteria were similar for all the exposure indicators. The estimated temperature-mortality relationship therefore did not appear to be significantly affected by the indicator used, regardless of study zone (departments or region) or age group. The increase in temperatures from the 90(th) to the 99(th) percentile of the temperature distribution led to a significant increase in mortality over 75 years (RR = 1.10 [95% CI, 1.07; 1.14]). Conversely, the decrease in temperature between the 10(th) and 1(st) percentile had a significant effect on the mortality under 75 years (RR = 1.04 [95% CI, 1.01; 1.06]). In the Paris area, there is no added value in taking multiple climatic stations into account when estimating exposure in time series studies. Methods to better represent the subtle temperature variations in densely populated areas in epidemiological studies are needed.

Signal detection in global mean temperatures after "Paris": an uncertainty and sensitivity analysis

Visser, Hans; Dangendorf, Sönke; van Vuuren, Detlef P.; Bregman, Bram; Petersen, Arthur C.

2018-02-01

In December 2015, 195 countries agreed in Paris to hold the increase in global mean surface temperature (GMST) well below 2.0 °C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5 °C. Since large financial flows will be needed to keep GMSTs below these targets, it is important to know how GMST has progressed since pre-industrial times. However, the Paris Agreement is not conclusive as regards methods to calculate it. Should trend progression be deduced from GCM simulations or from instrumental records by (statistical) trend methods? Which simulations or GMST datasets should be chosen, and which trend models? What is pre-industrial and, finally, are the Paris targets formulated for total warming, originating from both natural and anthropogenic forcing, or do they refer to anthropogenic warming only? To find answers to these questions we performed an uncertainty and sensitivity analysis where datasets and model choices have been varied. For all cases we evaluated trend progression along with uncertainty information. To do so, we analysed four trend approaches and applied these to the five leading observational GMST products. We find GMST progression to be largely independent of various trend model approaches. However, GMST progression is significantly influenced by the choice of GMST datasets. Uncertainties due to natural variability are largest in size. As a parallel path, we calculated GMST progression from an ensemble of 42 GCM simulations. Mean progression derived from GCM-based GMSTs appears to lie in the range of trend-dataset combinations. A difference between both approaches appears to be the width of uncertainty bands: GCM simulations show a much wider spread. Finally, we discuss various choices for pre-industrial baselines and the role of warming definitions. Based on these findings we propose an estimate for signal progression in GMSTs since pre-industrial.

Flashbulb memories of Paris attacks

Abstract Rationale: Flashbulb memories are detailed and vivid memories of attributes of the reception context of surprising and emotionally arousing public events. Patient concerns and diagnosis: This paper offers a fine-grained view of flashbulb memories in a patient with mild Alzheimer's disease (AD). Interventions: The patient underwent a directed interview about the 13 November 2015 attacks in Paris. Outcomes: Unlike her memory about the date and month of the attacks, the patient provided accurate information about the year, time and places they occurred. The patient also provided accurate information about how she first became aware of the attacks, where she was, with whom, what she was doing, and what time it was when she learned about them. As for the affective characteristics of these memories, she tended to have high ratings of vividness and rehearsal. Negative emotional states and great surprise and novelty were also reported. Lessons: By assessing the impact of flashbulb memories in this patient with AD, this paper offers a unique view into how such memories may trigger a considerable recall of context as well much subjective reliving.

Indoor aldehydes may result from ozone-initiated chemistry, mainly documented by experimental studies. As part of an environmental investigation included in the PARIS birth cohort, the aim of this study was to examine ozone contribution to airborne aldehyde formation in Paris homes. Formaldehyde, acetaldehyde and hexaldehyde levels, as well as styrene, nitrogen dioxide and nicotine concentrations, comfort parameters and carbon dioxide levels, were measured twice during the first year of life of the babies. Ambient ozone concentrations were collected from the closest background station of the regional air monitoring network. Traffic-related nitrogen oxide concentrations in front of the dwellings were estimated by an air pollution dispersion model. Home characteristics and families' way of life were described by questionnaires. Stepwise multiple linear regression models were used to link aldehyde levels with ambient ozone concentrations and a few aldehyde precursors involved in oxidation reactions, adjusting for other indoor aldehyde sources, comfort parameters and traffic-related nitrogen oxides. A 4 and 11% increase in formaldehyde and hexaldehyde levels was pointed out when 8-hour ozone concentrations increased by 20 μg/m(3). The influence of potential precursors such as indoor styrene level and frequent use of air fresheners, containing unsaturated volatile organic compounds as terpenes, was also found. Thus, our results suggest that ambient ozone can significantly impact indoor air quality, especially with regard to formaldehyde and hexaldehyde levels. Copyright © 2011 Elsevier B.V.

Urban dew and rain in Paris, France: Occurrence and physico-chemical characteristics

Beysens, D.; Mongruel, A.; Acker, K.

2017-06-01

This paper summarizes one year (April 2011 to March 2012) measurements on planar condensing surfaces of dew and rain events and related physico-chemical characteristics in the urban environment of Paris (city center). Yearly collected water was 3.48 mm for dew (63 events) and 593 mm for rain (146 events). The latter value compares well with rain data (547 mm and 107 events) collected within 12 km at Paris-Orly airport. An estimation of dew yield based on meteo data gives 2.35 mm and 74 events, to be compared with 17.11 mm and 196 events at Paris-Orly. These differences highlight the large reduction in dew events and dew yields in an urban area as compared to a close rural-like area. This reduction is not due to a sky view reduction but to heat island that increases air temperature and decreases relative humidity. Analysis of dew (34) and rain (77) samples were done concerning pH, electrical conductivity (EC), major anions and cations as well as selected trace metals and other minor ions. Mean pH values are found similar for both, dew (6.5) and rain (6.1), rain being slightly more acidic than dew. The mean dew total ionic content (TIC 1.8 meq/l) and EC value (124 μS/cm) are about four times that of rain (0.45 meq/l; 35 μS/cm), meaning that total dissolved solids in dew is nearly four times that in rain. Sulfate and nitrate are the most acidifying components, calcium the most neutralizing constituent with ratio of mean total acidity/total alkalinity comparable for dew and rain ( 0.9). Sulfate and nitrate have mainly anthropogenic sources, whereas chloride and magnesium are mostly connected with marine air masses. Dew is a considerable factor of wet deposition of pollutants; dew and rain ion concentrations, however, meet the WHO requirements for drinking water.

Implications of possible interpretations of "greenhouse gas balance" in the Paris Agreement

The main goal of the Paris Agreement as stated in its Article 2 is "Holding the increase in the global average temperature to well below 2°C above pre-industrial levels and pursuing efforts to limit the temperature increase to 1.5°C above pre-industrial levels…". Article 4 points to this long-term goal and the need to "… achieve balance between anthropogenic emissions by sources and removals by sinks of greenhouse gases …". The statement on "greenhouse gas balance" is subject to interpretation, and several clarifications are needed in order to make it operational for implementation in climate policies. Here we study possible interpretations from a scientific perspective and analyze their climatic implications. We clarify how the balance referred to in Article 4 of the Paris Agreement applies to anthropogenic sources and anthropogenic sinks and how the implications for individual gases depends strongly on the emission metrics used to relate them. We also show that the way in which balance is interpreted, achieved and maintained influences the anticipated temperature outcome over time. For example, achieving and maintaining net zero CO2-equivalent emissions calculated with the widely used metric Global Warming Potential with a horizon of 100 years (GWP100) - adopted for the implementation of the Kyoto Protocol and in UNFCCC reporting - would result in a peak and decline in global mean temperature. Adopting a different metric, like GWP* (Allen et al., 2016), would result in global mean temperatures remaining approximately constant once net zero CO2-equivalent emissions are achieved and maintained. Policymakers should be aware of these issues and choices and determine which approach is most appropriate in the context of the goals of the Paris Agreement.Reference:Allen, Fuglestvedt, Shine, Reisinger, Pierrehumbert, Forster: New use of global warming potentials to compare cumulative and short-lived climate pollutants.

Hydrological risks of a 2.0 oC warmer world: Assessing infrastructure exposure to the Paris Agreement.

The Conference of the Parties of the United Nations Framework Convention on Climate Change (UNFCC) in its Paris Agreement in December 2015 agreed to hold the increase in the global average temperature to well below 2.0 °C above pre- industrial levels. Nonetheless it is not yet clear how hydrological risks would change when this threshold is reached. In consequence, this may have important repercussions to existent or planned infrastructure as their functioning and the service they provide may be undermined if they do not adapt to shifts in water variability and, thus compromising global water security. In this study, we estimate the way in which hydrological risks will differ in a world 2 °C warmer. We used multi-ensembles outputs from 4 general circulation models (AOGCMs) participating in the HAPPI experimental protocol to generate global future river flows. From here we calculate extreme value probabilistics to calculate the increase in the frequency of the 100-year return period flow. Globally, we find that areas such as China and South Asia will be severly affecteed. Additional important changes are detected in Eastern Europe and in the area sorrounding the Gulf of California. Lastly, as a case study we show the implications of this climate target in the hydropower and transport infrastructure of Myanmar. We find that about 40% of mapped hydropower sites are in areas where the historical 100-year return period flow will significantly increase their frequency. We also find that about 30% of the roads and about 35% of the rail network of Myanmar are importantly exposed to such increases. We expect that this study is an initial step to analyse the propagation of hydrological risk associated with the Paris outcome; and thus, offer a tool to detect vulnerable population groups and economic sectors.

The second national ranking test took place in 2005 in the same conditions as the year before. Analysis of the results permits us to assess whether the objectives of this reform have been met so far. Data crossing of the results provided by the national testing center allowed us to rank: 1) the appeal of specializations for each geographic subdivision, 2) the candidates by medical school, and 3) the appeal of each subdivision by candidate rank. 66% of the students were classified high enough to be able to choose any specialization. Trends observed from the first examination, in 2004, were confirmed, with the clear desirability of medical specializations and a certain lack of interest in occupational medicine and public health. All the surgery posts were filled, even though the number of posts had increased enormously since the first examination. After adjustment for the number of posts available, the specializations in decreasing order of popularity were: medical, surgical, pediatrics, anesthesiology, gynecology-obstetrics, general medicine, psychiatry, and biology. Approximately 1000 posts in general medicine were not filled. The medical schools whose students ranked highest were Paris Pitié, Paris V, Paris West, Lyon North, Grenoble, and Aix-Marseille. Some medical schools did less well than previously: Marseille very slightly and Angers substantially. Strasbourg, Nancy Amiens and Bobigny were at the bottom of the list. The cities most desired for internships were Paris, Toulouse, Lyon, and Aix-Marseille, while Brest, Nancy, Limoges and the West Indies were ranked lowest, although each was chosen by highly ranked candidate. Two thirds of the students were ranked high enough to allow them a free choice of specializations. All the specializations except public health and occupational medicine had very highly ranked students. Medical specializations are the most desired, but surgery remains highly demanded, despite a substantial increase in the number of posts. All

Massage and medical gymnastics experienced a rapid institutionalization across Europe and North America between 1850 and 1914. This article explores how this process took place in London and Paris. Physiotherapy developed many of the hallmarks of an independent discipline during this period, including an identified corpus of manipulations and exercises, some autonomous training courses and degrees for future practitioners, and even the creation of departments within several hospitals. The article analyzes all of the processes surrounding this rise, paying special attention to the influence of the ambassadors of Swedish gymnastics (which led to the re-invention of massage across Europe), to the installation of physiotherapy in hospitals in London and in Paris, and to the practical and institutional innovations driven by nurses in England and by doctors in France.

Nude mice models with ovarian carcinoma were established by axillary subcutaneous inoculation of human SKOV3/DDP resistant ovarian cancer cell 200 µl and were used in the experiment. Treating the nude mice with Paris Phyllin VII combined with silica nano complex by gavage for 15 days to observe the weight change of the nude mice, tumor inhibition effect and changes of serum antioxidant capacity. Compared with the negative control group, tumor inhibition rate increased significantly in Paris Phyllin VII combined with silica nano complex treatment group, and was higher than that in both Paris Phyllin VII treatment only and silica nano composites treatment only group. The serum superoxide dismutase (SOD) and total antioxidant capacity (T-AOC) level of Paris Phyllin VII combined with silica nano complex treatment group was significantly higher than that of control group, Paris Phyllin VII treatment only and silica nano composites treatment only group. The serum malonaldehyde (MDA) level of Paris Phyllin VII combined with silica nano complex treatment group was significantly lower than that of the negative control group. Paris Phyllin VII combined with silica nano complex treatment can inhibit the ovarian carcinoma in nude mice, which may mediate by the enhancement of antioxidant capability in nude mice with ovarian cancer.

China still depends on coal for more than 60% of its power despite big investments in the process of shifting to nuclear, solar and wind power renewable energy resources alignment with Paris climate change agreement (Paris CCA). Chinese government through the Communist Party Central Committee (CPCC) ascribes great importance and commitment to Paris CCA legacy and history landmark implementation at all levels. As the world's biggest carbon dioxide emitter, China has embarked on "SMART" pollution and climate changes programs and measures to reduce coal-fired power plants to less than 50% in the next five years include: new China model of energy policies commitment on CO2 and greenhouse gas emissions reductions to less than 20% non-fossil energy use by 2030 without undermining their economic growth, newly introduced electric vehicles transportation benefits, interactive and sustained air quality index (AQI) monitoring systems, decreasing reliance on fossil fuel economic activities, revision of energy price reforms and renewable energy to less energy efficient technologies development. Furthermore, ongoing CPCC improved environmental initiatives, implemented strict regulations and penalties on local companies and firms' pollution production management, massive infrastructures such as highways to reduce CO2 expansion of seven regional emissions trading markets and programs for CO2 emissions and other pollutants are being documented. Maximizing on the centralized nature of the China's government, implemented Chinese pollution, climate changes mitigation and adaptation initiatives, "SMART" strategies and credible measures are promising. A good and practical example is the interactive and dynamic website and database covering 367 Chinese cities and providing real time information on environmental and pollution emissions AQI. Also, water quality index (WQI), radiation and nuclear safety monitoring and management systems over time and space. These are ongoing Chinese

An experimental setup for high-pressure liquid structure studies with synchrotron x-ray diffraction using the Paris-Edinburgh press has been installed at station 16-BM-B (HPCAT) of the Advanced Photon Source, Argonne National Laboratory. By collecting energy-dispersive data with a synchrotron white beam at various 2θ angles, the present device allows us to obtain the structure factor, S(Q), over a wide range of Q ( = 4πsinθ∕λ) owing to the excellent angular accessibility up to 37° in 2θ and high energy photons well beyond 100 keV. We have successfully collected XRD data on silicate (albite, NaAlSi(3)O(8)) liquids with Q up to ∼22 Å(-1) and pressure up to 5.3 GPa and temperature 1873 K, and obtained the radial distribution function, G(r), with a reasonable resolution. The T-O bond length (where T = Al, Si), which is a fundamental measure of local structure for aluminous silicate consisting of SiO(n) and AlO(n) polyhedra (tetrahedra at 1 atm condition), was found to be slightly shortened to 1.626 Å compared to that of glass at 1 atm. The T-O-T bound angle, which is the linkage of the above polyhedra, is the most responsible for densification. The T-O-T peak in G(r) splits into two peaks, suggesting a differentiation of the bond angle at high-pressure. The present technical development demonstrates that the Paris-Edinburgh press is suitable for studies of silicate liquids under high-pressure conditions.

This study analyzed the impact of area residential property values, an objective measure of socioeconomic status (SES), on self-rated health (SRH) in Seattle, Washington and Paris, France. This study brings forth a valuable comparison of SRH between cities that have contrasting urban forms, population compositions, residential segregation, food systems and transportation modes. The SOS (Seattle Obesity Study) was based on a representative sample of 1394 adult residents of Seattle and King County in the United States. The RECORD Study (Residential Environment and Coronary Heart Disease) was based on 7131 adult residents of Paris and its suburbs in France. Socio-demographics, SRH and body weights were obtained from telephone surveys (SOS) and in-person interviews (RECORD). All home addresses were geocoded using ArcGIS 9.3.1 (ESRI, Redlands, CA). Residential property values were obtained from tax records (Seattle) and from real estate sales (Paris). Binary logistic regression models were used to test the associations among demographic and SES variables and SRH. Higher area property values significantly associated with better SRH, adjusting for age, gender, individual education, incomes, and BMI. The associations were significant for both cities. A one-unit increase in body mass index (BMI) was more detrimental to SRH in Seattle than in Paris. In both cities, higher area residential property values were related to a significantly lower obesity risk and better SRH. Ranked residential property values can be useful for health and weight studies, including those involving social inequalities and cross-country comparisons.

While wheezing disorders are common in preschool children, their management is not well defined. The aim of this study was to assess the use of medical health care resources due to wheezing disorders in infants aged 18 months followed up in the Pollution and Asthma Risk: an Infant Study (PARIS) birth cohort. Data on wheezing disorders, medical visits and medication on account of respiratory disorders during the previous 12 months were collected with a standardized questionnaire, administered by a paediatrician, during the health check offered to every child aged 18 months included in the PARIS birth cohort. The prevalence of wheezing disorders during the past 12 months amounted to 560/1974 (28.4%). Among wheezers, 493 (89.3%) required a medical visit because of difficult breathing; 61 (11.0%) went to the emergency room, 35 (6.4%) were admitted to the hospital and 375 (67.2%) received an inhaled anti-asthmatic medication. Recourse to chest physiotherapy was reported in 472 of them (85.1%). This study confirms the high use of healthcare resources because of wheezing disorders in infants and suggests a higher use of anti-asthmatic medications in France compared to other European countries.

Little is known about the rate of crimes that are facilitated by the administration of psychoactive products without the victim's knowledge. This study analyzes the cases collected over a two-year period in a forensic unit in Paris. The study covers the period from January 1, 2005 and December /31, 2006. It includes crime victims who consulted for toxicological testing in the forensic unit of the Hôtel Dieu in Paris, after filing a criminal complaint describing symptoms suggestive of chemical submission (amnesia, impaired vigilance or behavior) and whose toxicological tests indicated the presence of a psychoactive product that they had not been aware of taking. The tests used chromatographic techniques on blood, urine, hair, and food or drink residue. Toxicological testing identified 52 cases of drug-facilitated crimes, primarily for theft and sexual abuse (including rape). The psychoactive products were most often incorporated in drinks, half of them alcoholic beverages. Benzodiazepines accounted for 77% of the cases. Other substances, found more rarely, included antihistamines, neuroleptics, and GHB. Appropriate samples must be taken from victims rapidly to enable toxicological analysis. Chromatographic analysis must supplement immunological analysis, which is not sufficiently specific or sensitive. The collection of this information must continue in order to quantify the phenomenon and monitor the emergence of new products.

On Friday November 13th at 9:20 pm, three kamikaze bombs went off around the Stade de France a stadium in Saint-Denis just outside Paris, 4 different shootings took place and bombings in Paris and hundreds of people were held hostage in a theater.This multi-site terrorist attack was the first of this magnitude in France. Drawing the lessons of these attacks and those which occurred in other countries from a health perspective is essential to continuously adapt and improve the French response to possible future attacks. Several issues would need to be further explored: Management of uncertainties: When to trigger the plans: after the 1st attack, the 2nd? When do attacks end and when to release mobilized resources? Management of victims: How to ensure that all victims are secured or taken care of? How to provide assistance when attacks are ongoing? Management of teams: Proper follow-up of persons involved in the response: health professionals, police and firemen, emergency call centers but also civil servants within administration that contributed to the response. Communication: Reactivity of all is a key element to secure appropriate resource is mobilized for the response. All actors have to be able to communicate quickly in a secured way.

Indoor airborne endotoxin assessment in homes of Paris newborn babies.

PubMed

2008-12-01

The aims of this study were first to assess airborne endotoxin levels in the dwellings of 162 newborns living in Paris twice during a 1-year period, and second, to identify predictors for endotoxin concentrations using questionnaire data in relation to housing factors and living conditions. Air samples were collected on a glass fiber filter in polystyrene filter holders, using a pump at a flow rate of 3.5 l/min for 24 h placed in the main room of the home. Endotoxin levels were measured using a chromogenic kinetic Limulus Amoebocyte Lysate test. Geometric means (geometric standard deviation) of airborne endotoxin levels at two different visits were respectively 0.509 (4.289) EU/m3 and 0.557 (3.029) EU/m3. Airborne endotoxin levels were significantly increased: (i) in cold season (P = 0.024), with (ii) the presence of visible cockroaches in the previous 12 months at home (P < 0.001), (iii) increased number of inhabitants per square meter (P = 0.012), (iv) the high frequency of cleaning with the floor cloths (P = 0.0014), and (v) the low frequency of vacuuming (P = 0.0045). This study provided for the first time airborne endotoxin levels issued from repeated measurements in Paris dwellings. PRACTICAL IMPLICATIONS This analysis contributed to identify a few factors that determined indoor airborne endotoxin levels. However, the predictive model including housing factors and living conditions poorly estimated endotoxin levels. Consequently, multiple samples and longer sampling periods might improve the estimate of long-term airborne endotoxin exposure especially its variability, in cohort studies.

Since the 1980s, the issue of social mix has become a public policy category in France. Enshrined in legislation, yet remaining controversial, it represents a major premise on which housing policies have been reconfigured. The concept of social mix is essentially based on who lives where, but it is also evoked in the context of urban renewal schemes for social housing estates, as well as in relation to new-build developments. A study of the bases of social mix policies conducted in Paris since 2001 in the context of the embourgeoisement of the capital shows the fundamental role of social housing stock. The City Council has become involved in policy decisions about both the location and the allocation of social housing. Particular attention has been paid to the middle classes in the name of the principle of ‘balancing the population’. In order to measure the effects of the policy, this article relies on an analysis of two City of Paris schemes that have the stated intent of creating social mix. One of these schemes consists of redeveloping a working-class neighbourhood, Goutte d'Or, while the other involves the new acquisition of social housing in various more affluent neighbourhoods in the capital. This comparative study of the population shows that, whether in a neighbourhood poised for gentrification or in a more affluent neighbourhood, this policy has major effects on forms of local social cohesion, setting in motion individual trajectories and reshaping social and/or ethnic identities.

2015-10-01

A specific smartphone application was developed to collect perceptive and acoustic data in Paris. About 3400 questionnaires were analyzed, regarding the global sound environment characterization, the perceived loudness of some emergent sources and the presence time ratio of sources that do not emerge from the background. Sound pressure level was recorded each second from the mobile phone's microphone during a 10-min period. The aim of this study is to propose indicators of urban sound quality based on linear regressions with perceptive variables. A cross validation of the quality models extracted from Paris data was carried out by conducting the same survey in Milan. The proposed sound quality general model is correlated with the real perceived sound quality (72%). Another model without visual amenity and familiarity is 58% correlated with perceived sound quality. In order to improve the sound quality indicator, a site classification was performed by Kohonen's Artificial Neural Network algorithm, and seven specific class models were developed. These specific models attribute more importance on source events and are slightly closer to the individual data than the global model. In general, the Parisian models underestimate the sound quality of Milan environments assessed by Italian people.

This study aimed to record and analyse incidence and characteristics of injuries and illnesses incurred during the Indoor Athletics Championships. During the 2011 European Indoor Athletics Championships in Paris, incidence and characteristics of new injuries and illnesses were recorded prospectively by physicians and physiotherapists from national teams and local organizing committee in 631 registered athletes. Around 70% of athletes were covered by the medical teams (response rate: 84%). Thirty injuries, including eight time-loss injuries, were reported, representing an incidence of 47.5 injuries and 29.4 time-loss injuries per 1000 registered athletes. Injury and time-loss injury risk were highest in heptathlon and hurdles. Three-quarters of injuries affected the lower extremity. Thigh strain was the most common diagnosis (n = 7; 23%). Noncontact trauma (n = 9; 30%) was the predominant cause. A total of 18 illnesses were reported. Incidence of illnesses was 28.5 per 1000 registered athletes, with 17% resulting in time lost from sport. Upper respiratory tract infection was the most common diagnosis (n = 8; 44%) followed by upper respiratory tract allergy (n = 3; 17%) and gastroenteritis (n = 3; 17%). Injury and illness incidence and severity were lower during the 2011 European Indoor Athletics Championships than during outdoor championships, probably due to the shorter duration, the fewer number of events, and shorter sprint distances. © 2012 John Wiley & Sons A/S.

Motivations. Road traffic and domestic wood burning emissions are two major contributors of particulate pollution in our cities. These two sources emit ultra-fine, soot containing, particles in the atmosphere, affecting health adversely, increasing morbidity and mortality from cardiovascular and respiratory conditions and casing lung cancer. A better characterization of soot containing aerosol sources in our major cities provides useful information for policy makers for assessment, implementation and monitoring of strategies to tackle air pollution issues affecting human health with additional benefits for climate change. Objectives. This study on local sources of primary Particulate Matter (PM) in the megacity of Paris is a follow-up of several programs (incl. EU-FP7-MEGAPOLI) that have shown that fine PM - in the Paris background atmosphere - is mostly secondary and imported. A network of 14 stations of Black Carbon has been implemented in the larger region of Paris to provide highly spatially resolved long term survey of local combustion aerosols. To our best knowledge, this is the first time that such densely BC network is operating over a large urban area, providing novel information on the spatial/temporal distribution of combustion aerosols within a post-industrialized megacity. Experimental. As part of the PRIMEQUAL "PREQUALIF" project, a dense Black Carbon network (of 14 stations) has been installed over the city of Paris beginning of 2012 in order to produce spatially resolved Equivalent Black Carbon (EBC) concentration maps with high time resolution through modeling and data assimilation. This network is composed of various real-time instruments (Multi-Angle Absorption Photometer, MAAP by THERMO; Multi-wavelength Aethalometers by MAGEE Scientific) implemented in contrasted sites (rural background, urban background, traffic) complementing the regulated measurements (PM, NOx) in the local air quality network AIRPARIF (http

2012-05-01

We present a short historical review on the major institutions and figures who contributed to make Paris a renowned centre of physiology and neurology during the XIXth and the first half of the XXth century. We purposely chose to focus on the period 1800-1950, as 1800 corresponds to the actual beginning of neurosciences, and as 1950 marks their exponential rise. Our presentation is divided into four chapters, matching the main disciplines that have progressed and contributed most to the knowledge we have of the brain sciences: anatomy, physiology, neurology, and psychiatry-psychology. The present article is the fourth of the four parts of this review, which deals with the chapter on psychiatry and psychology. When the French Revolution occurred, only a few institutions were taking care of the mentally ill. In the Paris area, these included Maison Royale de Charenton, Les Petites Maisons, and one of the departments of larger hospitals such as Hôtel-Dieu, the Salpêtrière Hospital and Bicêtre Hospital. One of the founders of psychiatry in Paris at that time and thereafter was Philippe Pinel (1745-1826) who was the first to distinguish insane/alienated patients from misfits, beggars, and other vagabonds. During the first half of the XIXth century, his student Jean-Étienne Esquirol (1772-1840) also played a major role with his treatise on mental diseases and the 1838 law and the creation of asylums in all parts of France. Alienists were in general caregivers and learned by themselves. In contrast, at the academic level, the emerging disciplines psychiatry and neurology were very close to each other in the second half of the XIXth century, the best example being Jules Baillarger (1809-1890). The actual development of psychiatry and psychology and the foundation of psychoanalysis later in the XIXth century and in the first half of the XXth century owed much to several European doctors and scientists, particularly those from British institutions and from German

P. polyphylla Smith is used in traditional medicine in China, India and Nepal and is likely to be similarly used through most of its geographic range. China is at the centre of demand for P. polyphylla where it is used as an ingredient in several very successful Chinese medicinal herbal formulations. The Chinese e-commerce platform 'alibaba.com', for example, lists 97 P. polyphylla items offered by 46 Asian suppliers, of which 21 are situated in the Chinese mainland, 12 in Nepal, 7 in India, 2 in Pakistan, and 1 each in Bhutan, Hong Kong, Thailand, and Vietnam. Products offered include the crude drug (dried whole or cut rhizomes), extracts and formulations containing this herbal drug. The aims of this review were to assess the scale of the P. polyphylla trade, reviewing evidence on the impacts of wild harvest on P. polyphylla populations and on the role of cultivation as an alternative to wild harvest. Firstly, we reviewed published information on Paris population biology and studies on impacts of wild P. polyphylla harvest from across the geographic range of this species. Secondly, global trade data for P. polyphylla were analysed. Thirdly, we reviewed published information on P. polyphylla cultivation and made field visits to P. polyphylla cultivation areas in Yunnan and Sichuan. Since the 1980s, there has been a 400-fold increase in the market price paid in China for P. polyphylla rhizomes, from 2.7 Chinese Yuan (CNY) per kg in the 1980s to market prices up to 1100 CNY per kg in 2017. Cross-border trade in dried P. polyphylla rhizomes occurs at three different scales. Firstly, an internal, national trade of P. polyphylla rhizomes within countries (such as India, Nepal and China). Secondly, trade in P. polyphylla rhizomes from Nepal (and possibly from Bhutan) to the two range states that have the largest traditional medicine trade in the world: China and India. Thirdly, trade in processed herbal products. In China, for example, P. polyphylla is widely used as

The concentration, degree of contamination and pollution of 7 trace elements (TEs) along an urban pressure gradient were measured in 180 lawn and wood soils of the Paris region (France). Iron (Fe), a major element, was used as reference element. Copper (Cu), cadmium (Cd), lead (Pb) and zinc (Zn) were of anthropogenic origin, while arsenic (As), chromium (Cr) and nickel (Ni) were of natural origin. Road traffic was identified as the main source of anthropogenic TEs. In addition, the industrial activity of the Paris region, especially cement plants, was identified as secondary source of Cd. Soil characteristics (such as texture, organic carbon (OC) and total nitrogen (tot N) contents) tell the story of the soil origins and legacies along the urban pressure gradient and often can explain TE concentrations. The history of the land-use types was identified as a factor that allowed understanding the contamination and pollution by TEs. Urban wood soils were found to be more contaminated and polluted than urban lawns, probably because woods are much older than lawns and because of the legacy of the historical management of soils in the Paris region (Haussmann period). Lawn soils are similar to the fertile agricultural soils and relatively recently (mostly from the 1950s onwards) imported from the surrounding of Paris, so that they may be less influenced by urban conditions in terms of TE concentrations. Urban wood soils are heavily polluted by Cd, posing a high risk to the biological communities. The concentration of anthropogenic TEs increased from the rural to the urban areas, and the concentrations of most anthropogenic TEs in urban areas were equivalent to or above the regulatory reference values, raising the question of longer-term monitoring.

In the early twentieth century, if there were an European Capital of biomedical research, it was definitely Paris. It was in this city where microbiology was born in the 19th century due to the crucial influence of Louis Pasteur. In 1888 he founded the Pasteur Institute in Paris where the rabies vaccine, that Pasteur himself had discovered in 1885, was administrated. This institution was also a place to continue his research on infectious diseases and to disseminate its findings. It is a private non-profit state-approved foundation that has attracted along the years many scientists from France and abroad who have been traditionally called "pasteuriens". So it was a world reference centre which has produced important scientific discoveries at a rapid pace and where resources both material and human, were abundant. The Pasteur institute therefore became one of the favourite research facilities of teachers and students from Spanish universities during the first third of the twentieth century, thanks to new regulations that encouraged training abroad. Scholarship policy promoted by the Spanish Government by an organization called Junta para la Ampliación de Estudios e Investigaciones Científicas (Council for Higher Studies and Scientific Research from, 1907 to 1936) formed scientists abroad. The Faculty of Pharmacy of Santiago de Compostela sent some of its members to the French capital between 1905 and 1933. We found that the vast majority chose the Pasteur Institute to conduct the studies of biological chemistry and drug synthesis, but always dependent of the Faculty of Pharmacy of Paris. Our study focuses on teachers and students who went to Paris, the dates, the course of their scientific stay and how these studies influenced their later work, once they returned to the Faculty of Pharmacy of Santiago de Compostela.

To evaluate the use of mannitol in prehospital care in Paris area. Survey using telephone interviews. Emergency physicians on duty in the 37 emergency departments in charge of prehospital care in Paris area were called by one investigator. They were asked to answer a questionnaire about their own use of mannitol in the prehospital setting. Ninety-six questionnaires were recorded. Physicians were anaesthesiologists (9%) or emergency physicians (87%). In three departments, mannitol was not available in the ambulances. Thirty-five per cent (n = 34) reported no use of mannitol and 17% (n = 16) just once. Fourteen physicians (15%) did not want to use it. The reasons for not using mannitol were lack of knowledge about efficacy for five, need for previous brain imaging for seven or neurosurgeon's agreement before using mannitol for three. For those who had already used mannitol or were ready to use it, the main indication was increased intracranial pressure with clinical signs of brain herniation after severe brain injury for 92% of physicians. Thirty-one % reported not knowing the dose of mannitol, 33% having a memorandum immediately available and among those who answered the question, 63% gave a value compatible with guidelines. A significant percentage of physicians tacking part in the French prehospital care system, do not follow published guidelines on the use of mannitol. Actions improving implementation of those guidelines should be supported.

Global mean sea-level rise in a world agreed upon in Paris

Although the 2015 Paris Agreement seeks to hold global average temperature to ‘well below 2 °C above pre-industrial levels and to pursue efforts to limit the temperature increase to 1.5 °C above pre-industrial levels’, projections of global mean sea-level (GMSL) rise commonly focus on scenarios in which there is a high probability that warming exceeds 1.5 °C. Using a semi-empirical model, we project GMSL changes between now and 2150 CE under a suite of temperature scenarios that satisfy the Paris Agreement temperature targets. The projected magnitude and rate of GMSL rise varies among these low emissions scenarios. Stabilizing temperature at 1.5 °C instead of 2 °C above preindustrial reduces GMSL in 2150 CE by 17 cm (90% credible interval: 14-21 cm) and reduces peak rates of rise by 1.9 mm yr-1 (90% credible interval: 1.4-2.6 mm yr-1). Delaying the year of peak temperature has little long-term influence on GMSL, but does reduce the maximum rate of rise. Stabilizing at 2 °C in 2080 CE rather than 2030 CE reduces the peak rate by 2.7 mm yr-1 (90% credible interval: 2.0-4.0 mm yr-1).

Feeding the city: food consumption and flow of nitrogen, Paris, 1801-1914.

The flows of foodstuffs (and the nitrogen they contain) through the city of Paris in the 19th and early 20th century were evaluated. Between 1801 and 1914, the fivefold increase in the population of Paris, as well as the threefold increase in the number of horses used in urban transport, gave rise to increased needs for food and feed. The corresponding inputs of nitrogen increased from 6000 tN/year in 1817 to 25,000 tN/year from the rural hinterland to the city. The corresponding per capita inflows were relatively stable throughout the period and may be divided into four more or less equal parts (flour, meat, other human foodstuffs, forage), each representing about 6 gN per inhabitant per day. In total, the demand for foodstuffs was of the order of 24 gN per inhabitant per day, one quarter of which was for transport. The fate of this dietary nitrogen after consumption changed a lot with the techniques used for exploiting urban excreta of all kinds, particularly of nitrogen, which was in great demand until the development of synthetic fertilizers. Dietary nitrogen flow diagrams are established for the years 1817, 1869 and 1913, and reveal an increasing improvement of the agricultural reuse (from 20 to 40% of the inflowing N).

This paper studies the seasonal variation of surface and column CO at three different sites (Paris, Jungfraujoch and Wollongong), with an emphasis on establishing a link between the CO vertical distribution and the nature of CO emission sources. We find the first evidence of a time lag between surface and free tropospheric CO seasonal variations in the Northern Hemisphere. The CO seasonal variability obtained from the total columns and free tropospheric partial columns shows a maximum around March-April and a minimum around September-October in the Northern Hemisphere (Paris and Jungfraujoch). In the Southern Hemisphere (Wollongong) this seasonal variability is shifted by about 6 months. Satellite observations by the IASI-MetOp (Infrared Atmospheric Sounding Interferometer) and MOPITT (Measurements Of Pollution In The Troposphere) instruments confirm this seasonality. Ground-based FTIR (Fourier transform infrared) measurements provide useful complementary information due to good sensitivity in the boundary layer. In situ surface measurements of CO volume mixing ratios at the Paris and Jungfraujoch sites reveal a time lag of the near-surface seasonal variability of about 2 months with respect to the total column variability at the same sites. The chemical transport model GEOS-Chem (Goddard Earth Observing System chemical transport model) is employed to interpret our observations. GEOS-Chem sensitivity runs identify the emission sources influencing the seasonal variation of CO. At both Paris and Jungfraujoch, the surface seasonality is mainly driven by anthropogenic emissions, while the total column seasonality is also controlled by air masses transported from distant sources. At Wollongong, where the CO seasonality is mainly affected by biomass burning, no time shift is observed between surface measurements and total column data.

Localising the nitrogen imprint of the Paris food supply: the potential of organic farming and changes in human diet

The Seine watershed has long been the food-supplying hinterland of Paris, providing most of the animal and vegetal protein consumed in the city. Nowadays, because of the land specialisation of agriculture made possible by the shift from manure-based to synthetic nitrogen fertilisation, the Seine watershed, although it exports 80% of its huge cereal production, still provides most of the cereal consumed by the Paris agglomeration. The meat and milk supply originate, however, mainly from regions in the North and West of France, specialised in animal farming and importing about 30% of their feed from South America. As it works today, this system is responsible for a severe nitrate contamination of surface groundwater resources. Herein two scenarios of re-localising Paris's food supply are explored, based on organic farming and local provision of animal feed. We show that for the Seine watershed it is technically possible to design an agricultural system able to provide all the plant- and animal-based food required by the population, to deliver sub-root water meeting the drinking water standards and still to export a significant proportion of its production to areas less suitable for cereal cultivation. Decreasing the share of animal products in the human diet has a strong impact on the nitrogen imprint of urban food supply.

Evidence of pre-industrial air pollution from the Heads of the Kings of Juda statues from Notre Dame Cathedral in Paris.

Pollution originating from wood combustion characterised the urban atmospheres of the past and led to the formation of thin grey crusts on the surface of the stone of monuments. The grey crusts discovered on the Heads of the Kings of Juda statues, which adorned the facade of Notre Dame in Paris from the 13th century until 1792, constitute a material record of the effects of this ancient air pollution. The height at which the statues stood suggests that the effect was not the result of a point phenomenon, but was caused by a generalised pollution of the Paris atmosphere at the time.

This study aimed to measure in French children personal exposure concentrations of black carbon (BC) and ultrafine particles (UFP) and to quantify the contribution of different microenvironments (home, school, places of extracurricular activities, transport) to their total exposure. It was conducted on 96 9-year-old children from the PARIS birth cohort. BC and UFP were continuously measured by portable devices (microAeth ® AE51 and DiSCmini ® ) for a minimum of 24 hours, while participating families simultaneously filled in a space-time-activities-budget questionnaire. BC exposure concentration was higher during trips (principally metro/train and bus), while UFP exposure concentration was higher during indoor activities (mainly eating at restaurants) and in trips. The most important UFP peaks were measured at home, especially during cooking. Home and school together accounted for much of the total exposure, 83.8% for BC and 85.3% for UFP. The contribution of transport to total exposure was 12.4% for BC and 9.7% for UFP, while extracurricular activities were responsible for 3.8% and 5% of the total exposure to BC and UFP, respectively. © 2016 John Wiley & Sons A/S.

Study of nano-architecture of the wings of Paris Peacock butterfly

NASA Astrophysics Data System (ADS)

Ghate, Ekata; Bhoraskar, S. V.; Kulkarni, G. R.

Butterflies are one of the most colorful creatures in animal Kingdom. Wings of the male butterfly are brilliantly colored to attract females. Color of the wings plays an important role in camouflage. Study of structural colors in case of insects and butterflies are important for their biomimic and biophotonic applications. Structural color is the color which is produced by physical structures and their interaction with light. Paris Peacock or Papilio paris butterfly belongs to the family Papilionidae. The basis of structural color of this butterfly is investigated in the present study. The upper surface of the wings in this butterfly is covered with blue, green and brown colored scales. Nano-architecture of these scales was investigated with scanning electron microscope (SEM) and environmental scanning electron microscope (ESEM). Photomicrographs were analyzed using image analysis software. Goniometric color or iridescence in blue and green colored scales of this butterfly was observed and studied with the help of gonio spectrophotometer in the visible range. No iridescence was observed in brown colored scales of the butterfly. Hues of the blue and green color were measured with spectrophotometer and were correlated with nano-architecture of the wing. Results of electron microscopy and reflection spectroscopy are used to explain the iridescent nature of blue and green scales. Sinusoidal grating like structures of these scales were prominently seen in the blue scales. It is possible that the structure of these wings can act as a template for the fabrication of sinusoidal gratings using nano-imprint technology.

Ozone, PM10 and PM2.5 concentrations over Paris, France and Stockholm, Sweden were modelled at 4 and 1 km horizontal resolutions respectively for the present and 2050 periods employing decade-long simulations. We account for large-scale global climate change (RCP-4.5) and fine-resolution bottom-up emission projections developed by local experts and quantify their impact on future pollutant concentrations. Moreover, we identify biases related to the implementation of regional-scale emission projections by comparing modelled pollutant concentrations between the fine- and coarse-scale simulations over the study areas. We show that over urban areas with major regional contribution (e.g. the city of Stockholm) the bias related to coarse-scale projections may be significant and lead to policy misclassification. Our results stress the need to better understand the mechanism of bias propagation across the modelling scales in order to design more successful local-scale strategies. We find that the impact of climate change is spatially homogeneous in both regions, implying strong regional influence. The climate benefit for ozone (daily mean and maximum) is up to -5 % for Paris and -2 % for Stockholm city. The climate benefit on PM2.5 and PM10 in Paris is between -5 and -10 %, while for Stockholm we estimate mixed trends of up to 3 % depending on season and size class. In Stockholm, emission mitigation leads to concentration reductions up to 15 % for daily mean and maximum ozone and 20 % for PM. Through a sensitivity analysis we show that this response is entirely due to changes in emissions at the regional scale. On the contrary, over the city of Paris (VOC-limited photochemical regime), local mitigation of NOx emissions increases future ozone concentrations due to ozone titration inhibition. This competing trend between the respective roles of emission and climate change, results in an increase in 2050 daily mean ozone by 2.5 % in Paris. Climate and not emission change

The Paris Observatory has 350 years

The Paris Observatory is the oldest astronomical observatory that has worked without interruption since its foundation to the present day. The building due to Claude Perrault is still in existence with few modifications, but of course other buildings have been added all along the centuries for housing new instruments and laboratories. In particular, a large dome has been built on the terrace in 1847, with a 38-cm diameter telescope completed in 1857: both are still visible. The main initial purpose of the Observatory was to determine longitudes. This was achieved by Jean-Dominique Cassini using the eclipses of the satellites of Jupiter: a much better map of France was the produced using this method, which unfortunately does not work at sea. Incidentally, the observation of these eclipses led to the discovery in 1676 of the finite velocity of light by Cassini and Rømer. Cassini also discovered the differential rotation of Jupiter and four satellites of Saturn. Then, geodesy was to be the main activity of the Observatory for more than a century, culminating in the famous Cassini map of France completed around 1790. During the first half of the 19th century, under François Arago, the Observatory was at the centre of French physics, which then developed very rapidly. Arago initiated astrophysics in 1810 by showing that the Sun and stars are made of incandescent gas. In 1854, the new director, Urbain Le Verrier, put emphasis on astrometry and celestial mechanics, discovering in particular the anomalous advance of the perihelion of Mercury, which was later to be a proof of General Relativity. In 1858, Leon Foucault built the first modern reflecting telescopes with their silvered glass mirror. Le Verrier created on his side modern meteorology, including some primitive forecasts. The following period was not so bright, due to the enormous project of the Carte du Ciel, which took much of the forces of the Observatory for half a century with little scientific return. In

Secondary pollutants such as ozone, secondary inorganic aerosol, and secondary organic aerosol formed in the plume of megacities can affect regional air quality. In the framework of the FP7/EU MEGAPOLI project, an intensive campaign was launched in the Greater Paris Region in July 2009. The major objective was to quantify different sources of organic aerosol (OA) within a megacity and in its plume. In this study, we use airborne measurements aboard the French ATR-42 aircraft to evaluate the regional chemistry-transport model CHIMERE within and downwind the Paris region. Slopes of the plume OA levels vs. Ox (= O3 + NO2) show secondary OA (SOA) formation normalized with respect to photochemical activity and are used for specific evaluation of the OA scheme in the model. Simulated and observed slopes are in good agreement, when the most realistic "high-NOx" yields are used in the Volatility-Basis-Set scheme implemented into the model. In addition, these slopes are relatively stable from one day to another, which suggest that they are characteristic for the given megacity plume environment. Since OA within the plume is mainly formed from anthropogenic precursors (VOC and primary OA, POA), this work allows a specific evaluation of anthropogenic SOA and SOA formed from primary semi-volatile and intermediate volatile VOCs (SI-SOA) formation scheme in a model. For specific plumes, this anthropogenic OA build-up can reach about 10 μg m-3. For the average of the month of July 2009, maximum increases occur close to the agglomeration for primary OA are noticed at several tens (for POA) to hundred (for SI-SOA) kilometers of distance from the Paris agglomeration.

This analyses makes use of the experiments and model data from the Half a degree Additional warming; Prognosis and Projected Impacts (HAPPI; www.happimip.org) analysis (Mitchell et al, 2016a). HAPPI is unique in that it is specifically designed to address the Paris Agreement priorities on climate impacts, by using equilibrated climates and super-ensembles, thereby enabling robust analysis of extremes. Here we first look at extreme hot and cold spells, and then make use of the most recent heat-mortality models, and heat stress metrics to look at any differences between 1.5C and 2C worlds compared to normal.

The Paris Agreement confirmed the global aim to achieve a long-term climate goal, in which the global increase in mean temperature is kept below 2 °C compared to the preindustrial level. We investigated the implications of the near-term emissions targets (for around the year 2030) in the context of the long-term climate mitigation goal using the Asia-Pacific Integrated Model framework. To achieve the 2 °C goal, a large greenhouse gas emissions reduction is required, either in the early or latter half of this century. In the mid-term (from 2030 to 2050), it may be necessary to consider rapid changes to the existing energy or socioeconomic systems, while long-term measures (after 2050) will rely on the substantial use of biomass combined with carbon capture and storage technology or afforestation, which will eventually realize so-called negative CO2 emissions. With respect to the policy context, two suggestions are provided here. The first is the review and revision of the nationally determined contributions (NDCs) in 2020, with an additional reduction target to the current NDCs being one workable alternative. The second suggestion is a concrete and numerical mid-term emissions reduction target, for example to be met by 2040 or 2050, which could also help to achieve the long-term climate goal.

Air pollution and its impacts are subject to an expanded interest since the middle of the 20th century, especially in urban areas which gathered an important part of emission sources. These polluted urban air masses are composed by a complex mixture of gases and aerosols coming from various emission sources (vehicular traffic, industries, residential heating, agricultural activities, natural sources) or chemical processes. To efficiently reduce this pollution and its impacts on population, it is important to understand its drivers, its sources and its impact on human health. To get some insights in Paris air pollution, a collaborative measurement platform called OCAPI ("Observation de la Composition Atmosphérique Parisienne de l'IPSL") has been built and implies several Parisian research laboratories of IPSL institute (CEREA, LSCE, LMD, LISA, LATMOS, LERMA and METIS) as well as public agencies and institutes in charge of Paris air pollution monitoring (AIRPARIF, INERIS). OCAPI platform aims at gathering skills and instruments of these laboratories to measure the composition and dynamics of Paris atmosphere. In this framework, multi-site measurements were performed during two intense particle pollution episodes which occurred in March 2016 and between November and December 2016. These two episodes were characterized by different meteorological conditions and different type of emission sources. Indeed, March episode was related to intense agricultural activities and high ammonium nitrate contribution to aerosol composition; while end of year episode was related to low wind speed, cold conditions and thin boundary layer which favoured the stagnation of locally emitted pollutants. This latter episode was characterized by large contribution of organics in aerosol composition. In this presentation, a study of these two episodes will be presented. We will first present the context and the OCAPI platform. Then, first results of dynamics and aerosol composition

Mapping the geometries (structure and lithology) of a buried basement is a key for targeting resources and for improving the regional geological knowledge. The Paris basin is a Mesozoic to Cenozoic intraplate basin set up on a Variscan substratum, which crops out in the surrounding massifs. We focus our study on the southwestern part of the Paris basin at its junction with the Aquitaine basin. This Mezo-Cenozoic cover separates the Armorican Massif and the Massif Central which compose of several litho-tectonic units bounded by crustal-scale shear zones. In spite of several lithological and structural correlations between various domains of the two massifs, their geological connection, hidden below the Paris basin sedimentary cover, is still largely debated. Potential field geophysics have proven effective for mapping buried basin/basement interfaces. In order to enhance the cartographic interpretation of these data, we have set up a detailed petrophysical library (field magnetic susceptibility data and density measurements on rock samples) of the Paleozoic rocks outcropping in the Variscan massifs. The combination of aeromagnetic and gravity data supported by the petrophysical signatures and field/borehole geological information, is carried out to propose a new map of the architecture of the Variscan substratum. The new synthetic map of geophysical signature of the Paris basin basement combines: i) the magnetic anomaly reduced to the pole, ii) the vertical gradient of the Bouguer anomaly and iii) the tilt derivative of the magnetic anomaly reduced to the pole. Based on this information, the Eastern extension of the major shear zones below the sedimentary cover is assessed. The petrophysical signatures were classified in three classes of magnetic susceptibility and density: low, intermediate and high. Basic rocks have high magnetization and density values whereas granite, migmatite and orthogneiss show low magnetization and density values, Proterozoic and Paleozoic

The Seine watershed has long been the food-supplying hinterland of Paris, providing most of the animal and vegetal protein consumed in the city. Nowadays, the shift from manure-based to synthetic nitrogen fertilisation, has made possible a strong land specialisation of agriculture in the Seine watershed: it still provides most of the cereal consumed by the Paris agglomeration, but exports 80% of its huge cereal production. On the other hand the meat and milk supply originates mainly from regions in the North and West of France, specialised in animal farming and importing about 30% of their feed from South America. As it works today, this system is responsible for a severe nitrate contamination of surface and groundwater resources. Herein two scenarios of re-localising Paris's food supply are explored, based on organic farming and local provision of animal feed. We show that for the Seine watershed it is technically possible to design an agricultural system able to provide all the plant- and animal-based food required by the population, to deliver sub-root water meeting the drinking water standards and still to export a significant proportion of its production to areas less suitable for cereal cultivation. Decreasing the share of animal products in the human diet has a strong impact on the nitrogen imprint of urban food supply.

Urban part of Seine River serving as drinking water supply in Paris can be heavily contaminated by Cryptosporidium spp. and Giardia duodenalis. In the absence of agricultural practice in this highly urbanized area, we investigated herein the contribution of treated wastewater to the microbiological quality of this river focusing on these two parasites. Other microorganisms such as faecal bacterial indicators, enteroviruses and oocysts of Toxoplasma gondii were assessed concurrently. Raw wastewaters were heavily contaminated by Cryptosporidium and Giardia (oo)cysts, whereas concentrations of both protozoa in treated wastewater were lower. Treated wastewater, flowed into Seine River, had a parasite concentration closed to the one found along the river, in particular at the entry of a drinking water plant (DWP). Even if faecal bacteria were reliable indicators of a reduction in parasite concentrations during the wastewater treatment, they were not correlated to protozoal contamination of wastewater and river water. Oocysts of T. gondii were not found in both raw and treated wastewater, or in Seine River. Parasitic contamination was shown to be constant in the Seine River up to 40 km upstream Paris. Altogether, these results strongly suggest that treated wastewater does not contribute to the main parasitic contamination of the Seine River usually observed in this urbanized area.

Identify which psychotropic medications are misused and peddled in a population of subjects held for custody in the city of Paris. Subjects held for custody in the Medico-Legal Emergency Unit of the Paris Hôtel-Dieu hospital were examined and interrogated between March 2006 and March 2007 in order to assess their consumption of psychotropic medications. Sixty one of the 659 subjects (9.2%) interrogated were included in the study. Their main source of psychotropic medications was street dealers. The most frequently misused psychotropic agent was clonazepam (42.6%), followed by buprenorphine (30.65%) and methadone (21.3%). Clonazepam appears to have replaced flunitrazepam which now only comes in fifth position (11.4%). The finding that methadone is the third most misused drug should lead us to query this medication's dispensing method. Practitioners should remain vigilant regarding the potential misuse of psychotropic medications, particularly since they may induce severe undesirable events (addiction, neurological disorders, possibly lethal overdosage).

Future Heat Waves in Paris Metropolitan Area

Cities are particularly vulnerable to heat waves, firstly because they concentrate the majority of the population and, secondly because the heat island that characterizes the urban climate exacerbates heat wave effects. This work is part of the interdisciplinary VURCA project (Vulnerability of cities to heat waves), which deals with the evolution of heat wave events in the context of global warming, urban vulnerability and adaptation strategies. The aim of this study is to analyse urban heat wave events in present climate (1950-2009) and their evolution in an enhanced greenhouse gazes future climate (2010-2100). We used daily observations of temperature from several stations covering Paris metropolitan area and climate projections following three different IPCC-SRES scenarios (B1, A1B, A2) and issued from several ENSEMBLES regional climate models. The heat wave definition is based on the indexes of the operational French warning system. A heat wave is detected within observed or simulated time-series by a heat wave peak, when the temperatures exceed the value of the 99.9th percentile. Its duration is determined by all adjacent days to this peak, for which the temperatures are not durably smaller than the 99.9th percentile value minus 2 °C. The 99.9th percentile threshold is inferred from quantile-quantile plots produced for each climate model in comparison with observations for the reference period 1950-2000. Heat waves have been extracted within observations and 12 climatic simulations. The number of heat wave events and cumulated HW days per year have been calculated, the maximum being seven heat waves cumulating more than 60 HW days in one year in the case of the A2 scenario and until 50 days in the case of the more moderate A1B scenario. From 2050, the occurrence of three or four HW events per year is becoming the norm all scenarios taken together. The evolution of heat wave features has been analysed, highlighting the large variability of the climatic

The banks of the River Seine in Paris are inscribed on the UNESCO List of the World Cultural Heritage since 1991 because they are studded with a succession of masterpieces such as Notre- Dame Cathedral, Sainte Chapelle, Louvre, Place de la Concorde, Tour Eiffel, and with prestigious museums: Louvre, Orsay, Quai Branly, Petit Palais…Unfortunately, these banks are crossed by the Pompidou urban motorway, an important and continuous source of atmospheric pollution. The aim of the Project is to evaluate the evolution of the weathering of limestone, glass and stained glass in the centre of Paris in the 21rst century by crossing Climate and Pollution Models with Dose-Response Functions (DRF) for limestone, glass and stained glass and with Climatology of Salt Transitions for limestone. A Lutetian limestone (« Courville Stone ») has been used for the construction and the restoration of the most important monuments (Notre-Dame, Louvre…) and haussmannian buildings in Paris. It has a fine grain, a medium porosity (19%) and contains 90% of CaO. The modern glass of windows and large contemporaneous façades has a Si-Ca-Na composition, it is chemically inert, has a low thermal inertia, a flat surface, no open porosity and no surface roughness, therefore it is very durable. The glass of stained glass windows has a Si-Ca-K composition and it is low durable. Using different climate and pollution scenarios of the 21rst century, the project will evaluate different schemes of material degradations: (i) - Recession of limestone surface; (ii) - Soiling of limestone surface; (iii) - Soiling of modern glass; (iv) - Leaching of ancient stained glass windows; (v) - Deterioration of limestone by salts. The British Hadley Models, the French Météo- France Arpège-Aladin Models and the ENSEMBLES Approach will be crossed with DRF and Climatology of Salts Transitions.

A growing fraction of the world's population is living in urban agglomerations of increasing size. Currently, 20 cities worldwide qualify as so-called megacities, having more than 10 million inhabitants. These intense pollution hot-spots cause a number of scientific questions concerning their influence on local and regional air quality, which is connected with human health, flora and fauna. In the framework of the European Union FP7 MEGAPOLI project (Megacities: Emissions, urban, regional and Global Atmospheric POLlution and climate effects, and Integrated tools for assessment and mitigation) two major field campaigns were carried out in the greater Paris region in July 2009 and January/February 2010. This work presents results from mobile particulate and gas phase measurements with focus on the characteristics of the Paris emission plume and its impact on the regional air quality and on aerosol transformation processes within this plume as it travels away from its source. In addition differences between summer and winter conditions are discussed. The mobile laboratory was equipped with high time resolution instrumentation to measure particle number concentrations (dP > 2.5 nm), size distributions (dP ~ 5 nm - 32 μm), sub-micron chemical composition (non-refractory species using Aerodyne HR-ToF-AMS, PAH and black carbon) as well as major trace gases (CO2, SO2, O3, NOx) and standard meteorological parameters. On-board webcam and GPS allow detailed monitoring of traffic situation and vehicle track. In a total of 29 mobile and 25 stationary measurements with the mobile laboratory the Paris emission plume as well as the atmospheric background was characterized under various meteorological conditions. This allows investigating the influence of external factors like temperature, solar radiation or precipitation on the plume characteristics. Three measurement strategies were applied to investigate the emission plume. First, circular mobile measurements around Paris

We present a device which allows compressed gases to be loaded into large volume opposed anvils used for high pressure neutron scattering in the multi-10 GPa range. The gases are initially loaded into clamps which can then be inserted into VX-Paris-Edinburgh load frames. The system is compatible with all inert gases as well as hydrogen and permits loading pressures of up to 3 kbar for which most gases have densities close to that of the liquid at ambient pressure. The device should have applications for the study of simple molecular solids as well as for loading gases as pressure-transmitting media.

ESC guidelines recommend a shorter (90 min) delay for the use of primary percutaneous intervention (pPCI) in patients presenting within the first 2h of pain onset. Using registry data on STEMI patients in the Greater Paris Area, we assessed changes between 2003 and 2008 in the rates of pPCI, pre-hospital fibrinolytic therapy (PHF) and time delays in patients presenting within 2h of STEMI pain onset. The Greater Paris Area was divided in 3 regions: Paris, the small and large rings. Patients were divided in three groups according to their reperfusion strategy: a) PHF, b) timely pPCI (FMC to balloon inflation time < 90 min), and c) late pPCI (FMC to balloon inflation time > 90 min). Among the 5592 patients included, 1695 (39%) had PHF, 1266 (29%) had timely pPCI, and 1415 (32%) had late pPCI. Over the 6 years, there was a sharp increase in timely pPCI in all regions, balanced by a decrease in PHF. The rate of late pPCI remained globally stable, with a decrease in Paris, stabilization in the small ring, and an increase in the large ring, where the density of catheterization laboratories was the lowest. By multivariate analysis, using on-time pPCI as a reference group, mortality was higher in the PHF and late pPCI groups. In areas with a low density of pPCI centers, efforts should be made to improve the timeliness of pPCI. Otherwise, PHF followed by an immediate transfer to a pPCI capable hospital may be considered. © 2013.

An Englishman abroad: Charles Blagden's visit to Paris in 1783.

Once the preliminaries of peace had been signed in January 1783, after the war of American independence, exchanges between British and French men of science resumed their normal course. On a visit to Paris in 1783, the francophile Charles Blagden (with the encouragement of Joseph Banks) made a number of contacts that fostered relations between the Royal Society and the Académie royale des sciences. In the course of this and several subsequent visits to France, Blagden became especially intimate with the chemist Claude-Louis Berthollet. His correspondence, now in the Royal Society, is a rich source for our understanding of some of the leading scientific debates of the day, in particular concerning the nature of water, which forms the main subject of this article.

Contemporary textbooks of anatomy and surface anatomy were evaluated to ascertain whether they were gender-neutral. The evidence of this, and previous studies, suggests that, both in terms of imagery and text, many textbooks lack neutrality. To further investigate such matters, we provided second-year medical students studying at Cardiff University (n = 293) and at the Paris Descartes University (n = 142) during the 2011-2012 academic year with a questionnaire inviting them to address the possibility that social/gender factors hinder the dispassionate representation of anatomy. Ethical approval was obtained from both Cardiff and Paris universities. Eighty-six percent of the students at Cardiff and 39% at Paris Descartes responded and provided data for analysis. The hypothesis tested is that medical students perceive a gender bias that is reflected in the books they read and the tuition they receive. Our findings suggest that, while students recognise the importance of gender issues and do not wish to associate with sexism, most are unaware of the possible negative aspects of sexism within anatomy. In this respect, the findings do not support our hypothesis. Nevertheless, we recommended that teachers of anatomy and authors of anatomy textbooks should be aware of the possibility of adverse effects on professional matters relating to equality and diversity issues. © 2013 Anatomical Society.

No European data currently describe the relation between neighbourhood socio-economic status (SES) and rates of out-of-hospital cardiac arrest (OHCA) bystander cardiopulmonary resuscitation (CPR). This study aims to analyse this effect with a robust deprivation index. Data about all OHCA in Paris were collected prospectively between 2000 and 2010. A geographical neighbourhood unit was assigned to each case. Median household income, and rates of blue-collar workers, unemployment, and adults without high school diplomas were selected as SES characteristics and used to classify neighbourhoods as low SES or higher SES. We analysed the relationship between neighbourhood SES characteristics and the probability of receiving bystander CPR. Of the 4009 OHCA with mappable addresses recorded, 777 (19.4%) received bystander CPR. Compared to OHCA who did not receive bystander CPR, those receiving CPR were significantly more likely to have occurred in public locations, have had a witness to their OHCA, and not to have collapsed in a low SES neighbourhood, or in a neighbourhood with a median household income in the lowest quartile and with rates of no high school diplomas and blue-collar workers in the highest quartile. In the multilevel analyses, bystander CPR provision was significantly less frequent in low than in higher SES neighbourhoods (OR 0.85; 95% confidence interval [CI] 0.72-0.99). In the city of Paris, OHCA victims were less likely to receive bystander CPR in low SES neighbourhoods. These first European data are consistent with observations in North America and Asia.

Mosses are useful, ubiquitous accumulation biomonitors and as such can be used for biomonitoring surveys. However, the biomonitoring of atmospheric pollution can be compromised in urban contexts if the targeted biomonitors are regularly disturbed, irregularly distributed, or are difficult to access. Here, we test the hypothesis that cemeteries are appropriate moss sampling sites for the evaluation of air pollution in urban areas. We sampled mosses growing on gravestones in 21 urban and peri-urban cemeteries in the Paris metropolitan area. We focused on Grimmia pulvinata (Hedwig) Smith, a species abundantly found in all studied cemeteries and very common in Europe. The concentration of Al, As, Br, Ca, Ce, Cl, Cr, Cu, Fe, K, Mn, Ni, V, P, Pb, Rb, S, Sr, Ti, and Zn was determined by a total reflection X-ray fluorescence technique coupled with a slurry sampling method (slurry-TXRF). This method avoids a digestion step, reduces the risk of sample contamination, and works even at low sample quantities. Elemental markers of road traffic indicated that the highest polluted cemeteries were located near the highly frequented Parisian ring road and under the influence of prevailing winds. The sites with the lowest pollution were found not only in the peri-urban cemeteries, adjoining forest or farming landscapes, but also in the large and relatively wooded cemeteries located in the center of Paris. Our results suggest that (1) slurry-TXRF might be successfully used with moss material, (2) G. pulvinata might be a good biomonitor of trace metals air pollution in urban context, and (3) cemetery moss sampling could be a useful complement for monitoring urban areas. Graphical abstract We tested the hypothesis that cemeteries are appropriate moss sampling sites for the evaluation of air pollution in urban areas.

This study aims to compare breast cancer screening (BCS) and cervical cancer screening (CCS) practices of French women born to French parents with those of immigrants and nationals born to immigrants, taking their socioeconomic status into account. The study is based on data collected in 2010 in the Paris metropolitan area among a representative sample of 3000 French-speaking adults. For women with no history of breast or cervical cancer, multivariate logistic regressions and structural equation models were used to investigate the factors associated with never having undergone BCS or CCS. We confirmed the existence of a strong gradient, with respect to migration origin, for delaying or never having undergone BCS or CCS. Thus, being a foreign immigrant or being French of immigrant parentage were risk factors for delayed and no lifetime screening. Interestingly, we found that this gradient persisted (at least partially) after adjusting for the women's socioeconomic characteristics. Only the level of income seemed to play a mediating role, but only partially. We observed differences between BCS and CCS which suggest that organized CCS could be effective in reducing socioeconomic and/or ethnic inequities. Socioeconomic status partially explained the screening nonparticipation on the part of French women of immigrant origin and foreign immigrants. This was more so the case with CCS than with BCS, which suggests that organized prevention programs might reduce social inequalities.

The Astronomical Photographic Data Archive (APDA) located at the Pisgah Astronomical Research Institute (PARI) was established in November 2007. APDA is dedicated to the task of collecting, restoring, preserving and storing astronomical photographic data and continues to accept collections. APDA is also tasked with scanning each image and establishing a database of images that can be accessed via the Internet by the global community of scientists, researchers and students. APDA is a new type of astronomical observatory - one that harnesses analog data of the night sky taken for more than a century and making that data digitally available. APDA is housed in a newly renovated Research Building on the PARI campus. An award from the NSF allowed renovation of the heating and air conditioning. Plates in APDA are kept in a 20 C +/- 1 C area with humidity at 38% +/- 3%. Renovation of the electrical system with backup power allows for support of a data center with a networked storage system and software donated from EMC Corp. The storage system can hold more than 400 terabytes of research data which can be accessed through multiple gigabyte connectivity to the Internet. APDA has a collection of more than 200,000 photographic plates and films from more than 40 collections, as well as major instrumentation, from NASA, the STScI, the US Naval Observatory, the Harvard Smithsonian CfA and others. APDA possesses two high precision glass plate scanners, GAMMA I and GAMMA II, built for NASA and the Space Telescope Science Institute (STScI). The scanners were used to develop the HST Guide Star Catalog and Digitized Sky Survey. GAMMA II has been rebuilt and we will report on its status as an astrometric measuring instrument.

It is now widely recognized that the complexity of climate change issues translates itself into a need for interdisciplinary approaches to science. This allows to first achieve a more comprehensive vision of climate change and, second, to better inform the decision-making processes. However, it seems that willingness alone is rarely enough to implement interdisciplinarity. The purpose of this presentation is to mobilize reflexivity to revisit and analyze the experience of the Paris Consortium for Climate-Environment-Society. The French Consortium Climate-Environment-Society aims to develop, fund and coordinate interdisciplinary research into climate change and its impacts on society and environment. Launched in 2007, the consortium relies on the research expertise of 17 laboratories and federation in the Paris area working mainly in the fields of climatology, hydrology, ecology, health sciences, and the humanities and social sciences. As examples, economists and climatologists have studied greenhouse gas emission scenarios compatible with climate stabilization goals. Historical records have provided both knowledge about past climate change and vulnerability of societies. Some regions, as the Mediterranean and the Sahel, are particularly vulnerable and already have to cope with water availability, agricultural production and even health issues. A project showed that millet production in West Africa is expected to decline due to warming in a higher proportion than observed in recent decades. Climate change also raises many questions concerning health: combined effects of warming and air quality, impacts on the production of pollens and allergies, impacts on infectious diseases. All these issues lead to a need for approaches integrating different disciplines. Furthermore, climate change impacts many ecosystems which, in turn, affect its evolution. Our experience shows that interdisciplinarity supposes, in order to take shape, the conjunction between programming

Particulate matter (PM) from atmospheric pollution can easily deposit in the lungs and induce recruitment of inflammatory cells, a source of inflammatory cytokines, oxidants, and matrix metalloproteases (MMPs), which are important players in lung structural homeostasis. In many large cities, the subway system is a potent source of PM emission, but little is known about the biological effects of PM from this source. We performed a comprehensive study to evaluate the biological effects of PM sampled at two sites (RER and Metro) in the Paris subway system. Murine macrophages (RAW 264.7) and C57Bl/6 mice, respectively, were exposed to 0.01-10 microg/cm2 and 5-100 microg/mouse subway PM or reference materials [carbon black (CB), titanium dioxide (TiO2), or diesel exhaust particles (DEPs)]. We analyzed cell viability, production of cellular and lung proinflammatory cytokines [tumor necrosis factor alpha (TNFalpha), macrophage inflammatory protein (MIP-2), KC (the murin analog of interleukin-8), and granulocyte macrophage-colony stimulating factor (GM-CSF)], and mRNA or protein expression of MMP-2, -9, and -12 and heme oxygenase-1 (HO-1). Deferoxamine and polymixin B were used to evaluate the roles of iron and endotoxin, respectively. Noncytotoxic concentrations of subway PM (but not CB, TiO2, or DEPs) induced a time- and dose-dependent increase in TNFalpha and MIP-2 production by RAW 264.7 cells, in a manner involving, at least in part, PM iron content (34% inhibition of TNF production 8 h after stimulation of RAW 264.7 cells with 10 microg/cm2 RER particles pretreated with deferoxamine). Similar increased cytokine production was transiently observed in vivo in mice and was accompanied by an increased neutrophil cellularity of bronchoalveolar lavage (84.83+/-0.98% of polymorphonuclear neutrophils for RER-treated mice after 24 h vs 7.33+/-0.99% for vehicle-treated animals). Subway PM induced an increased expression of MMP-12 and HO-1 both in vitro and in vivo. PM from the

The two Research Institutes, the CNR (National Research Institute, Italy) and the INRA (Institut National de Recherche Agronomique, France) which have been collaborating on the problem of cypress canker from Seiridium cardinale since 1975 in the context of EU projects, have measured in the SEM the pollen size of fourteen species of cypress, determining the differences between the maximum diameter of 100 granules per species and noting differences in pollen colour. A research strategy based on the use of material previously selectively bred for canker resistance is proposed to maintain the cypress in its Mediterranean habitat with a reduced risk of pollinosis. For the success of the project it is stressed that close collaboration between Forest research institutions and the medical profession will be necessary.

A Paris-Edinburgh cell (model VX-3) has been installed at HPCAT 16BM-B, a bending magnet white X-ray beamline at the Advanced Photon Source. The PE anvil and the heater assembly are specifically designed to contain the sample volume ranging from 0.03 mm3 to >1.2 mm3 while the entire sample volume can be seen through X-ray windows widely open in radial direction. The pressure and temperature of sample can reach up to 7 GPa and 2,300 K, respectively. For diffraction experiment, the maximum momentum transfer, Q = 4 πsin(θ) / λ, can reach up to ~40 Å -1. A real-time white-beam radiography imaging system obtains the absorption contrast images of compressed sample with 7x magnification, 5 μm image resolutions, and update rate of 0.1 msec to 60 sec per frame. A table top channel-cut monochromator which can provide 30-90 keV monochromatic X-rays is also available for transmission measurement. These series of new instrumental developments are expected to widen the range of user sciences at HPCAT with new opportunities for in-situ measurement of real-time radiography, amorphous and liquid structure, ultrasound velocity, density, electrical resistivity and thermal conductivity.

2011-01-01

In this contribution, we try to outline a history of the rise of orthopaedic and gymnastic clinics from 1820 to 1860 in France, and particularly in Paris. These clinics are located at the crossroads of several social processes of the 19th century: the structuring of a medical field (observed through specialization, professionalization, etc.), physical exercises legitimating process or the development of a medical interest for the female body. Several types of interests and issues--epistemological, educational, social, professional or symbolic--cross around those clinics and place them as major elements in the constitution of a history of medical engagement in the production of physical education during the nineteenth century. Divided in two parts, our presentation will try to highlight various elements of a history of those clinics' rise: their directors, a geography of the implantation in Paris and a description of their customers, looking at the various educational and rehabilitative methodologies implemented in the different clinics.

Since opening in 1848, Lariboisière's Hospital was strongly associated with the history of Paris and especially with the terrible days of the siege of Paris and the fights of the Commune. On the day after the surrender, Alix Joffroy wrote his first letter to his mother. He described the events as he experienced them, expressing his feelings about the causes of this political and military disaster and his experience there as an intern. Some weeks after the defeat of France by the Prussians, humbled Parisians attacked governmental troops. From March to May 1871 an improvised insurrectionary movement, The Commune of Paris, had taken power in the capital During the Bloody Week from 21 to 28 May 1871; this movement was suppressed by the Versaillaise Army. In his second letter, Joffroy related with great realism the tooth and nail fighting at the barricades and then the savage repression by the Army of the Communards around Lariboisière's Hospital. Two letters preciously preserved by Alix Joffroy's descendants give this man's unique direct account of a tragic period of the 19th century. © The Author(s) 2014.

'A thorn in the side of European geodesy': measuring Paris-Greenwich longitude by electric telegraph.

PubMed

Kershaw, Michael

2014-12-01

The difference in longitude between the observatories of Paris and Greenwich was long of fundamental importance to geodesy, navigation and timekeeping. Measured many times and by many different means since the seventeenth century, the preferred method of the later nineteenth and early twentieth centuries made use of the electric telegraph. I describe here for the first time the four Paris-Greenwich telegraphic longitude determinations made between 1854 and 1902. Despite contemporary faith in the new technique, the first was soon found to be inaccurate; the second was a failure, ending in Anglo-French dispute over whose result was to be trusted; the third failed in exactly the same way; and when eventually the fourth was presented as a success, the evidence for that success was far from clear-cut. I use this as a case study in precision measurement, showing how mutual grounding between different measurement techniques, in the search for agreement between them, was an important force for change and improvement. I also show that better precision had more to do with the gradually improving methods of astronomical, time determination than with the singular innovation of the telegraph, thus emphasizing the importance of what have been described as 'observatory techniques' to nineteenth-century practices of precision measurement.

Organic market gardening around the Paris agglomeration: agro-environmental performance and capacity to meet urban requirements.

Organic market gardening is often promoted by urban municipalities as a way to resource part of the food supply, creating new social links and protecting groundwater resources. The agronomical and environmental performance of six commercial organic market gardening farms supplying vegetables in Paris were evaluated and compared with other vegetable production systems. When expressed in terms of protein production, the yield of these systems appears rather low compared with the productive capacity of open-field organic cropping systems where vegetable production is inserted into rotation with other crops. Moreover, the requirement of producing infiltrated water meeting the drinking water standards seriously limits the allowable rate of fertilisation, thus limiting production. The data reported herein show that to supply the amount of vegetables required by the Paris agglomeration (12 million inhabitants) only by organic market gardening, 160,000-205,000 ha, i.e. 28-36 % of the agricultural area of the surrounding Ile-de-France region, would be required. We conclude that organic market gardening is only one of several other farming systems which can contribute to a re-localised supply of vegetables to large cities.

BACKGROUND Dose-related toxicity is the major restriction of cisplatin and cisplatin-combination chemotherapy, and is a challenge for advanced gastric cancer treatment. We explored the possibility of using Paris saponin I as an agent to sensitize gastric cancer cells to cisplatin, and examined the underlying mechanism. MATERIAL AND METHODS Growth inhibition was detected by MTT assay. The cell cycle and apoptosis were detected using flow cytometry and Annexin V/PI staining. The P21waf1/cip1, Bcl-2, Bax, and caspase-3 protein expression were detected using Western blot analysis. RESULTS The results revealed that PSI sensitized gastric cancer cells to cisplatin, with low toxicity. The IC50 value of cisplatin in SGC-7901 cell lines was decreased when combined with PSI. PSI promoted cisplatin-induced G2/M phase arrest and apoptosis in a cisplatin concentration-dependent manner. Bcl-2 protein expression decreased, but Bax, caspase-3, and P21waf1/cip1 protein expression increased with PSI treatment. CONCLUSIONS The underlying mechanism of Paris saponin I may be related to targeting the apoptosis pathway and cell cycle blocking, which suggests that PSI is a potential therapeutic sensitizer for cisplatin in treating gastric cancer.

We use a three-dimensional regional chemical transport model (PMCAMx) with high grid resolution and high-resolution emissions (4 × 4 km2) over the Paris greater area to simulate the formation of carbonaceous aerosol during a summer (July 2009) and a winter (January/February 2010) period as part of the MEGAPOLI (megacities: emissions, urban, regional, and global atmospheric pollution and climate effects, and Integrated tools for assessment and mitigation) campaigns. Model predictions of carbonaceous aerosol are compared against Aerodyne aerosol mass spectrometer and black carbon (BC) high time resolution measurements from three ground sites. PMCAMx predicts BC concentrations reasonably well reproducing the majority (70 %) of the hourly data within a factor of two during both periods. The agreement for the summertime secondary organic aerosol (OA) concentrations is also encouraging (mean bias = 0.1 µg m-3) during a photochemically intense period. The model tends to underpredict the summertime primary OA concentrations in the Paris greater area (by approximately 0.8 µg m-3) mainly due to missing primary OA emissions from cooking activities. The total cooking emissions are estimated to be approximately 80 mg d-1 per capita and have a distinct diurnal profile in which 50 % of the daily cooking OA is emitted during lunch time (12:00-14:00 LT) and 20 % during dinner time (20:00-22:00 LT). Results also show a large underestimation of secondary OA in the Paris greater area during wintertime (mean bias = -2.3 µg m-3) pointing towards a secondary OA formation process during low photochemical activity periods that is not simulated in the model.

Results also show a large underestimation of secondary OA in the Paris greater area during wintertime (mean bias = -2.3 μg m-3) pointing towards a secondary OA formation process during low photochemical activity periods that is not simulated in the model.

Contemporary textbooks of anatomy and surface anatomy were evaluated to ascertain whether they were gender-neutral. The evidence of this, and previous studies, suggests that, both in terms of imagery and text, many textbooks lack neutrality. To further investigate such matters, we provided second-year medical students studying at Cardiff University (n = 293) and at the Paris Descartes University (n = 142) during the 2011–2012 academic year with a questionnaire inviting them to address the possibility that social/gender factors hinder the dispassionate representation of anatomy. Ethical approval was obtained from both Cardiff and Paris universities. Eighty-six percent of the students at Cardiff and 39% at Paris Descartes responded and provided data for analysis. The hypothesis tested is that medical students perceive a gender bias that is reflected in the books they read and the tuition they receive. Our findings suggest that, while students recognise the importance of gender issues and do not wish to associate with sexism, most are unaware of the possible negative aspects of sexism within anatomy. In this respect, the findings do not support our hypothesis. Nevertheless, we recommended that teachers of anatomy and authors of anatomy textbooks should be aware of the possibility of adverse effects on professional matters relating to equality and diversity issues.

In the fast pace of the Emergency Department (ED), clinicians are in need of tailored screening tools to detect seniors who are at risk of adverse outcomes. We aimed to explore the usefulness of the Bergman-Paris Question (BPQ) to expose potential undetected geriatric syndromes in community-living seniors presenting to the ED. This is a planned sub-study of the INDEED multicentre prospective cohort study, including independent or semi-independent seniors (≥65 years old) admitted to hospital after an ED stay ≥8 hours and who were not delirious. Patients were assessed using validated screening tests for 3 geriatric syndromes: cognitive and functional impairment, and frailty. The BPQ was asked upon availability of a relative at enrolment. BPQ's sensitivity and specificity analyses were used to ascertain outcomes. A response to the BPQ was available for 171 patients (47% of the main study's cohort). Of this number, 75.4% were positive (suggesting impairment), and 24.6% were negative. To detect one of the three geriatric syndromes, the BPQ had a sensitivity of 85.4% (95% CI [76.3, 92.0]) and a specificity of 35.4% (95% CI [25.1, 46.7]). Similar results were obtained for each separate outcome. Odds ratio demonstrated a higher risk of presence of geriatric syndromes. The Bergman-Paris Question could be an ED screening tool for possible geriatric syndrome. A positive BPQ should prompt the need of further investigations and a negative BPQ possibly warrants no further action. More research is needed to validate the usefulness of the BPQ for day-to-day geriatric screening by ED professionals or geriatricians.

A diverse set of photometric, astrometric, spectral and surface brightness data exist on more than 100 years of photographic glass plates. About 20 percent of the plates in North America are located in the Astronomical Photographic Data Archive (APDA) at the Pisgah Astronomical Research Institute (PARI). APDA was established in November 2007 and is dedicated to the task of collecting, restoring, preserving and storing astronomical photographic data and PARI continues to accept collections. APDA is also tasked with scanning each image and establishing a database of images that can be accessed via the Internet by the global community of scientists, researchers and students. APDA is a new type of astronomical observatory - one that harnesses analog data of the night sky taken for more than a century and making that data available in a digital format. APDA currently has 50 collections with more than 250,000 plates taken for QSO identification, parallax measurements, spectral classification and monitoring, Magellanic Cloud studies, H-alpha emission star surveys, novae evolution, and astrometry of asteroids, outer planet satellites and Pluto. Some examples of collections include the complete set of the Henize H-alpha Southern Survey plates taken between 1949 and 1952 (Henize 1954, AJ, 59, 325), the Case Western Objective Prism All Sky Survey from 1958-1976 (e.g. Pesch, Sanduleak, and Stephenson 1996, ApJS, 103, 513), and QSO Survey from 1980 to 1991 (e.g. Pesch and Stephenson 1983, ApJS, 51, 171). We feature the contents of the APDA collections to provide the opportunity to the astronomical community to advance new and established areas of study.

The 128-km long-range artillery shelling of Paris is discussed considering its physical and chemical make-up from the vantage point of the technology in 1919. It compares this shelling with a hypothetical 240-km shelling and concludes that the most important influence on shelling range distance to be air resistance. The amount of air resistance and the resulting velocity deceleration depend on the air's density and the shell's velocity and configuration.

Spatio-temporal variability of the atmospheric boundary layer depth over the Paris agglomeration: An assessment of the impact of the urban heat island intensity

2012-12-01

Within the framework of a French nationally funded project (CO2-MEGAPARIS) for quantifying the CO2 emissions of the Paris area, a lidar-based experimental investigation of the variability of the atmospheric boundary layer (ABL) depths was performed over four days in March 2011 under clear sky conditions. The prevailing synoptic settings were mainly characterized by anti-cyclonic situations with low wind. The key aim of this paper is to assess the impact of the urban heat island intensity (UHII) on the spatio-temporal variability of the ABL depths over the Paris megacity. A network of fixed aerosol lidars was deployed inside the city and in the vicinity of sub-urban and rural areas. Additionally, the spatial heterogeneity of the nocturnal boundary layer (NBL) depths over greater Paris area is addressed, thanks in particular, to the deployment of a 355-nm elastic lidar in a mobile van to measure the aerosol distributions. Radiosonde-derived profiles (twice a day) of thermodynamic variables over the sub-urban site helped investigate the temperature inversion above ground and hence to compare the lidar-derived ABL depths. Comparing these two results, an excellent concordance was found with a correlation coefficient of 0.994. Five important factors closely related to the ABL circulation, namely, spatio-temporal variability of the ABL depths, growth rate of the ABL depths, entrainment zone thickness, and near-surface temperature fields including resultant UHII were considered to infer the urban-rural contrasts. The mean NBL depth over the urban area was on average 63 m (45%) higher than its adjacent sub-urban area which was, on occasion, as much as (74 m) 58% higher mainly due to the effect of UHII. Daytime well-mixed convective boundary layer and associated strong turbulent mixing near its top over the urban area showed higher entrainment zone thickness (326 m) than over sub-urban (234 m) and rural (200 m) areas. Temperature growth rates during sunrise increased up to

The aim of this study was to compare the courses in endodontics and to assess the treatment quality in the student clinics in two dental schools, in Malmö, Sweden and Paris, France. A further aim was to improve the curriculum development in Paris 5 and Malmö by testing student exchange programmes. The comparison was based on the guidelines for undergraduate education set up by the European Society of Endodontology (ESE) [Int. Endod. J. 25 (1992) 169] and on the criteria formulated by Qualtrough and Dummer [Int. Endod. J. 30 (1997) 234]. The latter criteria covered the following aspects: educational methods, the timing of endodontic teaching, pre-clinical practical exercises, student assessment, recommended literature, clinical/practical procedures, the education of the staff and number of students per teacher. The quality guidelines for endodontic treatment set up by the ESE [Int. Endod. J. 27 (1994) 115] were used for the assessment of the quality of the treatment. The following aspects were covered: history, diagnosis and treatment planning, records, infection control, root-canal treatment, assessment of endodontic treatment. The undergraduate education in endodontics was fundamentally similar in Paris 5 and Malmö. The main differences observed were related to: Educational methods: In Malmö, problem-based learning and in Paris 5, traditional. Assessment of student performance. In Malmö, self-assessment and in Paris 5, credits for clinical/practical procedures. Clinical/practical procedures relating to infection control. Aseptic treatment regimens were more meticulously performed in Malmö than in Paris 5. Assessment (follow-up) of all endodontic treatments was a routine only in Malmö.

Atmospheric concentration measurements are used to adjust the daily to monthly budget of CO2 emissions from the AirParif inventory of the Paris agglomeration. We use 5 atmospheric monitoring sites including one at the top of the Eiffel tower. The atmospheric inversion is based on a Bayesian approach, and relies on an atmospheric transport model with a spatial resolution of 2 km with boundary conditions from a global coarse grid transport model. The inversion tool adjusts the CO2 fluxes (anthropogenic and biogenic) with a temporal resolution of 6 h, assuming temporal correlation of emissions uncertainties within the daily cycle and from day to day, while keeping the a priori spatial distribution from the emission inventory. The inversion significantly improves the agreement between measured and modelled concentrations. However, the amplitude of the atmospheric transport errors is often large compared to the CO2 gradients between the sites that are used to estimate the fluxes, in particular for the Eiffel tower station. In addition, we sometime observe large model-measurement differences upwind from the Paris agglomeration, which confirms the large and poorly constrained contribution from distant sources and sinks included in the prescribed CO2 boundary conditions These results suggest that (i) the Eiffel measurements at 300 m above ground cannot be used with the current system and (ii) the inversion shall rely on the measured upwind-downwind gradients rather than the raw mole fraction measurements. With such setup, realistic emissions are retrieved for two 30 day periods. Similar inversions over longer periods are necessary for a proper evaluation of the results.

Unprecedented climate events: Historical changes, aspirational targets, and national commitments.

The United Nations Paris Agreement creates a specific need to compare consequences of cumulative emissions for pledged national commitments and aspirational targets of 1.5° to 2°C global warming. We find that humans have already increased the probability of historically unprecedented hot, warm, wet, and dry extremes, including over 50 to 90% of North America, Europe, and East Asia. Emissions consistent with national commitments are likely to cause substantial and widespread additional increases, including more than fivefold for warmest night over ~50% of Europe and >25% of East Asia and more than threefold for wettest days over >35% of North America, Europe, and East Asia. In contrast, meeting aspirational targets to keep global warming below 2°C reduces the area experiencing more than threefold increases to <10% of most regions studied. However, large areas-including >90% of North America, Europe, East Asia, and much of the tropics-still exhibit sizable increases in the probability of record-setting hot, wet, and/or dry events.

Hydrocarbons and CO{sub 2} are mainly biogenic, He displays high concentrations. He, Ar and N{sub 2} have multiple origins (radioactive decay, atmospheric migration, biochemical processes). The distribution of the gases in the zones of the basin varies in relation to the general chemistry, sedimentology and hydrodynamics. The gas geothermometers do not apply to this environment but useful estimations of the redox potential of the fluid can be derived from CO{sub 2}/CH{sub 4} and N{sub 2}/NH{sub 4}{supmore » +} ratios.

After being appointed "premier physician" in 1731, Pierre Chirac, thanks to his influence with the king, tried to realize an ambitious project. Inspired by the creation of an Academie de Chirurgie by the "premier surgeon", Chirac decided to creation an Académie de Médecine in Paris. Under his guidance, it was planned to collect opinions from all doctors of the kingdom in order to enhance global knowledge of disease, symptoms and treatments. However, threatened with the loss of its secular superiority, the Paris University Medical School immediately opposed the project. Although well advanced, the project was finally abandoned on Chirac's death.

The histories of medical entomology and parasitology are entwined. Raphaël Blanchard (1857-1919), Chair of Medical Natural History and Parasitology at the Faculty of Medicine in Paris, organized the teaching of medical entomology and civilian colonial medicine. He also founded and edited the journal Archives de Parasitologie and started the Institute de Médecine Coloniale where he mentored many foreign students and researchers. Additionally, Blanchard is important for his scientific internationalism and medical historical work on the cultural location of parasitology and for training the future professors of parasitology Jules Guiart, Emile Brumpt, and Charles Joyeux.

This medical history essay claims that a medical fraud was committed by the authorities and was used as a pretext for the November 1938 anti-jewish Kristallnacht pogrom throughout the Third Reich. The suggested conspiracy covered up the real cause of death of the German Embassy's secretary in Paris. Baron Ernst vom Rath had been shot by a Jewish teenager who was frantic because of the plight of his family. A surgical analysis of the victim's injuries, and of the medical attention he received, suggests the likelihood of medical malpractice which led to his preventable demise.

Sudden cardiac death (SCD) is a major public health concern, but data regarding epidemiology of this disease in Western European countries are outdated. This study reports the first results from a large registry of SCD. A population-based registry was established in May 2011 using multiple sources to collect every case of SCD in Paris and its suburbs, covering a population of 6.6 million. Utstein variables were recorded. Pre-hospital and in-hospital data were considered, and the main outcome was survival at hospital discharge. Neurologic status at discharge was established as well. Of the 6,165 cases of SCD recorded over 2 years, 3,816 had a resuscitation attempt and represent the study population. Most patients were male (69%), the SCD occurred at home (72%) with bystanders in 80% of cases, and cardiopulmonary resuscitation (CPR) was performed in 45% of cases. Initial rhythm was shockable in 26% of cases. A total of 1,332 patients (35%) were admitted alive to hospital. Among hospitalized patients, 58% had a coronary angiogram, and the same proportion had therapeutic hypothermia. Finally, 279 patients (7.5%) were discharged alive, of whom 96% had a favorable neurological outcome. In multivariate analysis, bystander CPR (OR 2.1, 95% CI 1.5-3.1) and initial shockable rhythm (OR 11.5, 95% CI 7.6-17.3) were positively associated with survival at hospital discharge, whereas age (OR 0.97 per year, 95% CI 0.96-0.98), longer response time (OR 0.93 per minute, 95% CI 0.89-0.97), occurrence at home (OR 0.4, 95% CI 0.3-0.6), and epinephrine dose greater than 3 mg (OR 0.05, 95% CI 0.03-0.08) were inversely associated with survival. Despite being conducted in the therapeutic hypothermia and early coronary angiogram era, hospital discharge survival rate of resuscitated SCD remains poor. The current registry suggests ways to improve pre-hospital and in-hospital care of these patients.

Accurate simulation of the spatial and temporal variability of tracer mixing ratios over urban areas is challenging, but essential in order to utilize CO2 measurements in an atmospheric inverse framework to better estimate regional CO2 fluxes. This study investigates the ability of a high-resolution model to simulate meteorological and CO2 fields around Paris agglomeration, during the March field campaign of the CO2-MEGAPARIS project. The mesoscale atmospheric model Meso-NH, running at 2 km horizontal resolution, is coupled with the Town-Energy Balance (TEB) urban canopy scheme and with the Interactions between Soil, Biosphere and Atmosphere CO2-reactive (ISBA-A-gs) surface scheme, allowing a full interaction of CO2 between the surface and the atmosphere. Statistical scores show a good representation of the Urban Heat Island (UHI) and urban-rural contrasts. Boundary layer heights (BLH) at urban, sub-urban and rural sites are well captured, especially the onset time of the BLH increase and its growth rate in the morning, that are essential for tall tower CO2 observatories. Only nocturnal BLH at sub-urban sites are slightly underestimated a few nights, with a bias less than 50 m. At Eiffel tower, the observed spikes of CO2 maxima occur every morning exactly at the time at which the Atmospheric Boundary Layer (ABL) growth reaches the measurement height. The timing of the CO2 cycle is well captured by the model, with only small biases on CO2 concentrations, mainly linked to the misrepresentation of anthropogenic emissions, as the Eiffel site is at the heart of trafic emission sources. At sub-urban ground stations, CO2 measurements exhibit maxima at the beginning and at the end of each night, when the ABL is fully contracted, with a very strong spatio-temporal variability. The CO2 cycle at these sites is generally well reproduced by the model, even if some biases on the nocturnal maxima appear in the Paris plume parly due to small errors on the vertical transport, or in

High uncertainties affect black carbon (BC) emissions, and, despite its important impact on air pollution and climate, very few BC emissions evaluations are found in the literature. This paper presents a novel approach, based on airborne measurements across the Paris, France, plume, developed in order to evaluate BC and NOx emissions at the scale of a whole agglomeration. The methodology consists in integrating, for each transect, across the plume observed and simulated concentrations above background. This allows for several error sources (e.g., representativeness, chemistry, plume lateral dispersion) to be minimized in the model used. The procedure is applied with the CHIMERE chemistry-transport model to three inventories - the EMEP inventory and the so-called TNO and TNO-MP inventories - over the month of July 2009. Various systematic uncertainty sources both in the model (e.g., boundary layer height, vertical mixing, deposition) and in observations (e.g., BC nature) are discussed and quantified, notably through sensitivity tests. Large uncertainty values are determined in our results, which limits the usefulness of the method to rather strongly erroneous emission inventories. A statistically significant (but moderate) overestimation is obtained for the TNO BC emissions and the EMEP and TNO-MP NOx emissions, as well as for the BC / NOx emission ratio in TNO-MP. The benefit of the airborne approach is discussed through a comparison with the BC / NOx ratio at a ground site in Paris, which additionally suggests a spatially heterogeneous error in BC emissions over the agglomeration.

One of the greatest achievements in the global negotiations of 2015 that delivered the 2030 Agenda for Sustainable Development or Sustainable Development Goals (SDGs) and the Paris Agreement on climate change is that, for the first time, the linkages between climate and development were enshrined in each of the documents. This was done in recognition that climate change and development need to be addressed together in order not only to avoid harmful trade-offs and high costs, particularly for poorer countries, but also to exploit the benefits that come from strengthening these linkages. This review presents some of the latest data that argue for stronger linkages as well as the challenges of implementation which are not only politically and economically related but also include issues such as knowledge gaps, finance and governance. Finally, the review also presents a glimpse at the pathways that will be required to reach the ambitious global temperature targets of the Paris Agreement of less than 2°C above pre-industrial levels with efforts to limit temperature rise even further to 1.5°C. This provides the context for some conclusions and recommendations for policy-makers, including on methodologies for assessing linkages and leveraging them for greater benefit.

This review presents some of the latest data that argue for stronger linkages as well as the challenges of implementation which are not only politically and economically related but also include issues such as knowledge gaps, finance and governance. Finally, the review also presents a glimpse at the pathways that will be required to reach the ambitious global temperature targets of the Paris Agreement of less than 2°C above pre-industrial levels with efforts to limit temperature rise even further to 1.5°C. This provides the context for some conclusions and recommendations for policy-makers, including on methodologies for assessing linkages and leveraging them for greater benefit. This article is part of the theme issue `The Paris Agreement: understanding the physical and social challenges for a warming world of 1.5°C above pre-industrial levels'.

In France, mealtimes constitute a strong cultural trait, especially the three-meal pattern. The aim of our study was to test whether this pattern is still prevailing and to what extent familial structure, gender, poverty and migration have an effect on meal frequency. This study is based on a cross-sectional analysis of data collected in 2010 in the SIRS cohort study among a representative sample of 3006 adults in the Paris metropolitan area. We developed simple logistic models and multinomial logistic models. Results confirmed that the three-meal pattern remains strongly rooted in food habits in the Paris area. For three meals a day, the presence of a partner was more significant than the presence of children in the household. However, the study highlighted that one out of four inhabitants declared eating two meals a day only. The results emphasized gender differences in eating two meals a day, as being less frequent but more distinctive for women than for men. For women indeed, it was mainly linked to economic and social vulnerability (women below the poverty line, foreigners, in single parent families). In this respect, the paper provides new insights into the social differentiation of meal patterns, and calls for further analysis. Copyright © 2012 Elsevier Ltd. All rights reserved.

Modelling transport of storm-water pollutants using the distributed Multi-Hydro platform on an urban catchment near Paris

Nowadays, the increasingly use of vehicles causes expanding contaminated storm-water runoff from roads and the associated quarters. Besides, the current utilization of city's separated sewer systems underlines the needs for evaluating precisely the growing impact of these polluted effluents on receiving water bodies. Nevertheless, traditional means of water quality modelling had shown its limits (Kanso, 2004), more accurate modelling schemes are hence required. In this paper, we found that the application of physically based and fully distributed model coupled with detailed high-resolution data is a promising approach to reproduce the various dynamics and interactions of water quantity/quality processes in urban or peri-urban environment. Over recent years, the physically based and spatially distributed numerical platform Multi-Hydro (MH) has been developed at Ecole des Ponts ParisTech (El-Tabach et al. , 2009 ; Gires et al., 2013 ; Giangola-Murzyn et al., 2014). This platform is particularly adapted for representing the hydrological processes for medium size watersheds, including the surface runoff, drainage water routing and the infiltrations on permeable zones. It is formed by the interactive coupling of several independent modules, which depend on generally used open-access models. In the framework of the ANR (French National Agency for Research) Trafipollu project, a new extension of MH, MH-quality, was set up for the water-quality modelling. MH-quality was used for the simulation of pollutant transport on a peri-urban and highly trafficked catchment located near Paris (Le Perreux-sur-Marne, 0.2 km2). The set-up of this model is based on the detailed description of urban land use features. For this purpose, 15 classes of urban land uses relevant to water quality modelling were defined in collaboration with the National Institute of Geography of France (IGN) using Digital Orthophoto Quadrangles (5cm). The delimitation of the urban catchment was then performed

Ozone and PM2.5 concentrations over the city of Paris are modeled with the CHIMERE air-quality model at 4 km × 4 km horizontal resolution for two future emission scenarios. High-resolution (1 km × 1 km) emission projection until 2020 for the greater Paris region is developed by local experts (AIRPARIF) and is further extended to year 2050 based on regional scale emission projections developed by the Global Energy Assessment. Model evaluation is performed based on a 10 yr control simulation. Ozone is in very good agreement with measurements while PM2.5 is underestimated by 20% over the urban area mainly due to a large wet bias in wintertime precipitation. A significant increase of maximum ozone relative to present time levels over Paris is modeled under the "business as usual" scenario (+7 ppb) while a more optimistic mitigation scenario leads to moderate ozone decrease (-3.5 ppb) in year 2050. These results are substantially different to previous regional scale projections where 2050 ozone is found to decrease under both future scenarios. A sensitivity analysis showed that this difference is due to the fact that ozone formation over Paris at the current, urban scale study, is driven by VOC-limited chemistry, whereas at the regional scale ozone formation occurs under NOx-sensitive conditions. This explains why the sharp NOx reductions implemented in the future scenarios have a different effect on ozone projections at different scales. In rural areas projections at both scales yield similar results showing that the longer time-scale processes of emission transport and ozone formation are less sensitive to model resolution. PM2.5 concentrations decrease by 78% and 89% under "business as usual" and "mitigation" scenarios respectively compared to present time period. The reduction is much more prominent over the urban part of the domain due to the effective reductions of road transport and residential emissions resulting in the smoothing of the large urban increment

Exhaust particle emissions are mostly made of black carbon and/or organic compounds, with some of these organic compounds existing in both the gas and particle phases. Although emissions of volatile organic compounds (VOC) are usually measured at the exhaust, emissions in the gas phase of lower volatility compounds (POAvapor) are not. However, these gas-phase emissions may be oxidised after emission and enhance the formation of secondary organic aerosols (SOA). They are shown here to contribute to most of the SOA formation in Central Paris. POAvapor emissions are usually estimated from primary organic aerosol emissions in the particle phase (POA). However, they could also be estimated from VOC emissions for both gasoline and diesel vehicles using previously published measurements from chamber measurements. Estimating POAvapor from VOC emissions and ageing exhaust emissions with a simple model included in the Polyphemus air-quality platform compare well to measurements of SOA formation performed in chamber experiments. Over Greater Paris, POAvapor emissions estimated using POA and VOC emissions are compared using the HEAVEN bottom-up traffic emissions model. The impact on the simulated atmospheric concentrations is then assessed using the Polyphemus/Polair3D chemistry-transport model. Estimating POAvapor emissions from VOC emissions rather than POA emissions lead to lower emissions along motorway axes (between -50% and -70%) and larger emissions in urban areas (up to between +120% and +140% in Central Paris). The impact on total organic aerosol concentrations (gas plus particle) is lower than the impact on emissions: between -8% and 25% along motorway axes and in urban areas respectively. Particle-phase organic concentrations are lower when POAvapor emissions are estimated from VOC than POA emissions, even in Central Paris where the total organic aerosol concentration is higher, because of different assumptions on the emission volatility distribution, stressing the

Many experts on vaccination are convinced that efforts should be made to encourage increased collaboration between National Immunization Technical Advisory Groups on immunization (NITAGs) worldwide. International meetings were held in Berlin, Germany, in 2010 and 2011, to discuss improvement of the methodologies for the development of evidence-based vaccination recommendations, recognizing the need for collaboration and/or sharing of resources in this effort. A third meeting was held in Paris, France, in December 2014, to consider the design of specific practical activities and an organizational structure to enable effective and sustained collaboration. The following conclusions were reached: (i) The proposed collaboration needs a core functional structure and the establishment or strengthening of an international network of NITAGs. (ii) Priority subjects for collaborative work are background information for recommendations, systematic reviews, mathematical models, health economic evaluations and establishment of common frameworks and methodologies for reviewing and grading the evidence. (iii) The programme of collaborative work should begin with participation of a limited number of NITAGs which already have a high level of expertise. The amount of joint work could be increased progressively through practical activities and pragmatic examples. Due to similar priorities and already existing structures, this should be organized at regional or subregional level. For example, in the European Union a project is funded by the European Centre for Disease Prevention and Control (ECDC) with the aim to set up a network for improving data, methodology and resource sharing and thereby supporting NITAGs. Such regional networking activities should be carried out in collaboration with the World Health Organization (WHO). (iv) A global steering committee should be set up to promote international exchange between regional networks and to increase the involvement of less experienced

The Paris Agreement requires countries to articulate near-term emissions reduction strategies through to 2025 or 2030 by communicating nationally determined contributions (NDCs), as well as encouraging the formulation of long-term low-emission development strategies (Article 4.19)1. In response, many countries have either submitted or are preparing mid-century strategies2. Most NDCs set high-level near-term goals—such as limits on emissions or emissions intensity3—which do not provide information about the extent to which they lay the foundations of technology, infrastructure and institutions for deeper reductions in the future, which is a key question for decision makers. Here, using a state-level model of the US embedded within a global integrated assessment model4,5, we demonstrate that although the US NDC lies on a straight-line emissions pathway towards its mid-century strategy, the resulting energy system transitions involve nonlinear transformations. The rates of capacity additions and capital investments in electricity generation beyond 2025 are more than three times the rates during the next decade. Our results demonstrate the need for global stocktaking exercises to evaluate the NDCs using metrics broader than emissions to better illuminate their effectiveness in addressing the Paris Agreement's long-term goals6,7.

Introduction Poor air quality (AQ) is a global public health issue and AQ events can span across countries. Using emergency department (ED) syndromic surveillance from England and France, we describe changes in human health indicators during periods of particularly poor AQ in London and Paris during 2014. Methods Using daily AQ data for 2014, we identified three periods of poor AQ affecting both London and Paris. Anonymised near real-time ED attendance syndromic surveillance data from EDs across England and France were used to monitor the health impact of poor AQ. Using the routine English syndromic surveillance detection methods, increases in selected ED syndromic indicators (asthma, difficulty breathing and myocardial ischaemia), in total and by age, were identified and compared with periods of poor AQ in each city. Retrospective Wilcoxon-Mann-Whitney tests were used to identify significant increases in ED attendance data on days with (and up to 3 days following) poor AQ. Results Almost 1.5 million ED attendances were recorded during the study period (27 February 2014 to 1 October 2014). Significant increases in ED attendances for asthma were identified around periods of poor AQ in both cities, especially in children (aged 0–14 years). Some variation was seen in Paris with a rapid increase during the first AQ period in asthma attendances among children (aged 0–14 years), whereas during the second period the increase was greater in adults. Discussion This work demonstrates the public health value of syndromic surveillance during air pollution incidents. There is potential for further cross-border harmonisation to provide Europe-wide early alerting to health impacts and improve future public health messaging to healthcare services to provide warning of increases in demand.

Lorenz Oken and Naturphilosophie in Jena, Paris and London.

PubMed

Breidbach, Olaf; Ghiselin, Michael T

2002-01-01

Although Lorenz Oken is a classic example of Naturphilosophie as applied to biology, his views have been imperfectly understood. He is best viewed as a follower of Schelling who consistently attempted to apply Schelling's ideas to biological data. His version of Naturphilosophic, however, was strongly influenced by older pseudoscience traditions, especially alchemy and numerology as they had been presented by Robert Fludd, whose works were current in Jena and available to him. According to those influences, parts of Oken's philosophical conception were communicable even in a non-idealistic scientific culture, for example in Paris, where Oken met Etienne Geoffroy Saint-Hilaire. Geoffroy however was embedded in a French intellectual tradition, and the correspondence between his views and those of Oken was only superficial. The English anatomist Richard Owen attempted to incorporate the views of Oken and Geoffroy within his own, idiosyncratic system. Although Darwin knew of Oken's ideas, it was Geoffroy who really affected his evolutionary biology, and any influence of Oken must have been attenuated to the point of triviality.

This article presents the biographies of the apothecaries who lived in the Rue Saint-Honoré in Paris in the 17th century. Two major facts emerge from this study. The first concerns the formation of a family network involving the apothecaries and the royal artists. The apothecaries Antoine and Jacques Grégoire became allied with Simon Vouet, the first painter of Louis XIII . Links were also made between Antoine Grégoire and Jacques Sarazin, the King’s sculptor, and then with Michel Corneille, painter to the King. The famous painting by Simon Vouet hanging in the assembly hall of the Faculty of Pharmacy in Paris is probably the fruit of his collaboration with Jacques Grégoire, his brother-in-law and an erudite botanist. The other notable fact concerns the relations between Anne de Furnes, widow of Antoine Brulon, the rich apothecary to the King Antoine Brulon, and Molière, both in Paris and in the village of Auteuil.

Soil moisture characteristics predicted by the Arya-Paris model were compared with the laboratory measured data for 181 New Jersey soil horizons. For a number of soil horizons, the predicted and the measured moisture characteristic curves are almost coincident; for a large number of other horizons, despite some disparity, their shapes are strikingly similar. Uncertainties in the model input and laboratory measurement of the moisture characteristic are indicated, and recommendations for additional experimentation and testing are made.

This study investigates the use of The Paris System (TPS) for Reporting Urinary Cytopathology and examines the performance of individual and combined morphological features in atypical urine cytologies. We reviewed 118 atypical cytologies with subsequent bladder biopsies for the presence of several morphological features and reclassified them into Paris System categories. The sensitivity and specificity of individual and combined features were calculated along with the risk of malignancy. An elevated nuclear-to-cytoplasmic ratio was only predictive of malignancy if seen in single cells, while irregular nuclear borders, hyperchromasia, and coarse granular chromatin were predictive in single cells and in groups. Identification of coarse chromatin alone yielded a malignancy risk comparable to 2-feature combinations. The use of TPS criteria identified the specimens at a higher risk of malignancy. Our findings support the use of TPS criteria, suggesting that the presence of coarse chromatin is more specific than other individual features, and confirming that cytologic atypia is more worrisome in single cells than in groups. © 2017 S.

Retrieval of Paris CO2 and CO emissions using a boundary layer budget method in the framework of the CO2-MEGAPARIS project

The development of anthropogenic activities since the pre-industrial era has greatly increased CO2 concentrations in the atmosphere, very likely causing the observed rise in global temperature. Therefore, accurate estimations of CO2 emission fluxes are very important for climate predictions. At the continental scale, CO2 fluxes can be estimated rather precisely using inverse modeling while tower turbulent flux measurements (eddy-covariance or EC) can provide an estimation of local-scale fluxes. However, this method cannot be applied to monitor urban CO2 emissions due to their large horizontal variability, so that a regional scale approach seems more suited. Unfortunately, at this scale, anthropogenic and biospheric fluxes are mixed, diluted and advected in the atmospheric boundary-layer (ABL) and the balance between these processes is not well known. Yet, independent estimations of CO2 fluxes would be needed to verify existing high resolution emission inventories and assess the efficiency of future mitigation policies. Several experiments dedicated to quantifying CO2 emissions from megacities are ongoing, like the CO2-MEGAPARIS research project [a,b]. In this framework, a network of lidars and in-situ sensors has been set up in Paris region. An original ABL mass budget method is used to infer the properties of advected anthropogenic CO2 and CO emissions from Paris urban area [c]. The method is applied in the center of Paris, at neighboring suburban sites located 20 km away, and at a rural station (100 km downwind). The budget uses ABL depths from elastic lidars, CO2 and CO concentrations from both the ICOS [d] and CO2-MEGAPARIS networks to quantify vertical advection and storage terms in the ABL mass budget. EC measurements are used to monitor biospheric surface fluxes. The budget in Paris provides a direct estimation of the average CO2 and CO fluxes from the city, while the budget at the suburban and rural stations provides an estimation of the advected fluxes

Uncertainties on the origin of primary and secondary particulate matter and its gaseous precursors in megacities is still large and needs to be reduced. A detailed characterization of air quality in Paris (France), a megacity of more than 10 million inhabitants, during two one month intensive campaigns (MEGAPOLI) and from additional one year observations (PARTICULATE and FRANCIPOL), revealed that about 70% of the fine particulate matter (PM) at urban background is transported on average into the megacity from upwind regions. While advection of sulfate is well documented for other megacities, there was a surprisingly high contribution from long-range transport for both nitrate and organic aerosol. The data set of urban local and advected PM concentrations in the Paris area were used for a thorough evaluation of the CHIMERE model and revealed error compensation for the local and advected components of organic matter and nitrate. During spring time, CHIMERE simulations overestimate the sensitivity of ammonium nitrate peaks to NH3, because (i) they underestimate the urban background NH3 levels, probably due to neglecting enhanced NH3 emissions for larger temperatures, and because they overestimate HNO3. However, from an ensemble of mobile Max-DOAS NO2 column and airborne NOy measurements around Paris, no clear sign on a NOx emission bias in the TNO-Airparif data set was made evident. The origin of organic PM was investigated by a comprehensive analysis of aerosol mass spectrometer (AMS), radiocarbon and tracer measurements during two intensive campaigns. Primary fossil fuel combustion emissions contributed less than 20% in winter and 40% in summer to carbonaceous fine PM, unexpectedly little for a megacity. Cooking activities and, during winter, residential wood burning are the major primary organic PM sources. This analysis suggests that the major part of secondary organic aerosol is of modern origin, i.e. from biogenic precursors and from wood burning. Implementation

A feature of French geothermal engineering is the development of industrial projects in normal gradient, non-convective areas. The economic feasibility of exploiting wells producing between 150 and 350 m{sup 3}/h at temperatures from 55° to 85° from depths of 1,500 to 2,000 meters, in sedimentary basins with normal gradient, for direct heat production has been proved by 50 plants providing heating for over 500,000 people during the last few years. This opens new possibilities for geothermal energy development the world over, in particular for areas where heat consumption is higher than 2,500 Tons oil equivalent (Toe)/year over several square kilometers.more » The recent and rapid development of geothermal projects in France, in particular in the Paris Basin has provided much more information on the characteristics of the Jurassic Dogger, which is the unit tapped by geothermal doublets (one production and one injection well).

Endemic malaria has been eradicated from France, but some falciparum malaria cases have been described in patients who have never travelled outside the country. Ms. V. 21 year-old and Mr. M. 23 year-old living together in Paris were on holiday in Saint Raphaël (French Riviera). They presented with fever, vertigo and nausea. A blood smear made to control thrombocytopaenia revealed intra-erythrocytic forms of Plasmodium falciparum. The parasitaemia level was 0.15% for Ms. V and 3.2% for Mr. M. This couple had no history of blood transfusion or intravenous drug use. They had never travelled outside metropolitan France, but had recently travelled around France: to Saint Mard (close to Paris Charles de Gaulle (CdG) airport), to Barneville plage (in Normandy) and finally to Saint Raphaël. The most probable hypothesis is an infection transmitted in Saint Mard by an imported anopheline mosquito at CdG airport. The DNA analysis of parasites from Ms. V.'s and Mr. M.'s blood revealed identical genotypes. Because it is unlikely that two different anopheline mosquitoes would be infected by exactly the same clones, the two infections must have been caused by the infective bites of the same infected mosquito.

On November 13, 2015, Paris and Saint-Denis were the targets of terrorist attacks. The Public Hospitals of Paris Organization and the Percy Armed Forces Instruction Hospitals were mobilized to face the mass casualty situation. The objective of this study is to analyze the management of the victims presenting with a nonthoracic vascular trauma (NTVT). All the data relating to the victims of NTVT who required a specific vascular open or endovascular treatment were analyzed retrospectively. A 6-month follow-up was obtained for all the patients. Among the 351 wounded, 20 (5.7%) patients had an NTVT and were dispatched in 8 hospitals (11 men of average age 32). NTVTs were gunshots in 17 cases (85%) or due to a handmade bomb in 3 cases (15%). Twelve patients (60%) received cardiopulmonary resuscitation during prehospital care. NTVT affected the limbs (14 cases, 70%) and the abdomen or the small pelvis (6 cases, 30%). All the patients were operated in emergency. Arterial lesions were treated with greater saphenous vein bypasses, by ligation, and/or embolization. Eleven venous lesions were treated by direct repair or ligation. Associated lesions requiring a specific treatment were present in 19 patients (95%) and were primarily osseous, nervous, and abdomino-pelvic. Severe postoperative complications were observed in 9 patients (45%). Fourteen patients (70%) required blood transfusion (6.4 U of packed red blood cells on average, range 0-48). There were no deaths or amputation and all vascular reconstructions were patent at 6 months. The effectiveness of the prehospital emergency services and a multisite and multidisciplinary management made it possible to obtain satisfactory results for NTVT casualties. All the departments of vascular surgery must be prepared to receive many wounded victims in the event of terrorist attacks. Copyright © 2017 Elsevier Inc. All rights reserved.

The United Nations Paris Agreement creates a specific need to compare consequences of cumulative emissions for pledged national commitments and aspirational targets of 1.5° to 2°C global warming. We find that humans have already increased the probability of historically unprecedented hot, warm, wet, and dry extremes, including over 50 to 90% of North America, Europe, and East Asia. Emissions consistent with national commitments are likely to cause substantial and widespread additional increases, including more than fivefold for warmest night over ~50% of Europe and >25% of East Asia and more than threefold for wettest days over >35% of North America, Europe, and East Asia. In contrast, meeting aspirational targets to keep global warming below 2°C reduces the area experiencing more than threefold increases to <10% of most regions studied. However, large areas—including >90% of North America, Europe, East Asia, and much of the tropics—still exhibit sizable increases in the probability of record-setting hot, wet, and/or dry events.

GreenLITE™ is a ground-based laser absorption spectroscopy system capable of measuring and mapping CO2 concentrations over areas up to 25 km2. The system was deployed for COP21 as a demonstration and has now completed a year of CO2 measurements over the city of Paris, France. We will discuss lessons learned and relevant data from the year-long deployment. Recently, the system has demonstrated the same measurement capability for CH4, and results from preliminary testing are presented.

Long-term hydrodynamic response induced by past climatic and geomorphologic forcing: The case of the Paris basin, France

In the framework of safe underground storage of radioactive waste in low-permeability layers, it is essential to evaluate the mobility of deep groundwaters over timescales of several million years. On these timescales, the environmental evolution of a repository should depend upon a range of natural processes that are primarily driven by climate and geomorphologic variations. In this paper, the response of the Paris basin groundwater system to variations in its hydrodynamic boundary conditions induced by past climate and geodynamic changes over the last five million years is investigated. A three-dimensional transient modelling of the Paris basin aquifer/aquitard system was developed using the code NEWSAM (Ecole des Mines de Paris, ENSMP). The geometry and hydrodynamic parameters of the model originate from a basin model, NEWBAS (ENSMP), built to simulate the geological history of the basin. Geomorphologic evolution is deduced from digital elevation model analysis, which allows to estimate river-valley incision and alpine surrection. Climate forcing results from palaeoclimate modelling experiments using the LMDz atmospheric general circulation model (Institut Pierre Simon Laplace) with a refined spatial resolution, for the present, the Last Glacial Maximum (21 ka) and the Middle Pliocene Warmth (˜3 Ma). The water balance is computed by the distributed hydrological model MODSUR (ENSMP). Results about the simulated evolution of piezometric heads in the system in response to the altered boundary conditions are presented, in particular in the vicinity of ANDRA’s Bure potential repository site within the Callovo-Oxfordian argillaceous layer. For the present, the comparison of head patterns between steady state and time dependent simulation shows little differences for aquifer layers close to the surface but suggests a transient state of the current system in the main aquitards of the basin and in the deep aquifers, characterized by abnormally low fluid potentials

Accounting of GHG emissions and removals from forest management: a long road from Kyoto to Paris.

PubMed

Krug, Joachim H A

2018-01-03

Forests have always played an important role in agreeing on accounting rules during the past two decades of international climate policy development. Starting from activity-based gross-net accounting of selected forestry activities to mandatory accounting against a baseline-rules have changed quite rapidly and with significant consequences for accounted credits and debits. Such changes have direct consequences on incentives for climate-investments in forestry. There have also been strong arguments not to include forests into the accounting system by considering large uncertainties, procedural challenges and a fear of unearned credits corrupting the overall accounting system, among others. This paper reflects the development of respective accounting approaches and reviews the progress made on core challenges and resulting incentives. The historic development of forest management accounting rules is analysed in the light of the Paris Agreement. Pros and cons of different approaches are discussed with specific focus on the challenge to maintain integrity of the accounting approach and on resulting incentives for additional human induced investments to increase growth for future substitution and increased C storage by forest management. The review is solely based on scientific publications and official IPCC and UNFCC documents. Some rather political statements of non-scientific stakeholders are considered to reflect criticism. Such sources are indicated accordingly. Remaining and emerging requirements for an accounting system for post 2030 are highlighted. The Paris Agreement is interpreted as a "game changer" for the role of forests in climate change mitigation. Many countries rely on forests in their NDCs to achieve their self-set targets. In fact, the agreement "to achieve a balance between anthropogenic emissions by sources and removals by sinks of greenhouse gases in the second half of this century" puts pressure on the entire land sector to contribute to overall

Respiratory syncytial virus (RSV) is one of the most common respiratory pathogens in infants and young children. It is not known why some previously healthy infants, when in contact with RSV, develop bronchiolitis whereas others have only mild symptoms. Our study aimed to evaluate the possible association between emergency hospital visits for bronchiolitis and air pollution in the Paris region during four winter seasons. We included children under the age of 3 years who attended emergency room services for bronchiolitis (following standardized definition) during the period 1997-2001. Two series of data from 34 hospitals, the daily number of emergency hospital consultations (n=50857) and the daily number of hospitalizations (n=16588) for bronchiolitis, were analyzed using alternative statistical methods; these were the generalized additive model (GAM) and case-crossover models. After adjustments for public holidays, holidays and meteorological variables the case-crossover model showed that PM10, BS, SO2 and NO2 were positively associated with both consultations and hospitalizations. GAM models, adjusting for long-term trend, seasonality, holiday, public holiday, weekday and meteorological variables, gave similar results for SO2 and PM10. This study shows that air pollution may act as a trigger for the occurrence of acute severe bronchiolitis cases.

Indoor tetrachloroethylene levels and determinants in Paris dwellings.

There is growing public health concern about indoor air quality. Tetrachloroethylene (PERC), a chlorinated volatile organic compound widely used as a solvent in dry cleaning facilities, can be a residential indoor air pollutant. As part of an environmental investigation included in the PARIS (Pollution and asthma Risk: an Infant Study) birth cohort, this study firstly aimed to document domestic PERC levels, and then to identify the factors influencing these levels using standardized questionnaires about housing characteristics and living conditions. Air samples were collected in the child's bedroom over one week using passive devices when infants were 1, 6, 9, and 12 months. PERC was identified and quantified by gas chromatography/mass spectrometry. PERC annual domestic level was calculated by averaging seasonal levels. PERC was omnipresent indoors, annual levels ranged from 0.6 to 124.2 μg/m3. Multivariate linear and logistic regression models showed that proximity to dry cleaning facilities, do-it-yourself activities (e.g.: photographic development, silverware), presence of air vents, and building construction date (<1945) were responsible for higher domestic levels of PERC. This study, conducted in an urban context, provides helpful information on PERC contamination in dwellings, and identifies parameters influencing this contamination. Copyright © 2012 Elsevier Inc.

Due to their relatively high concentration in urban environments (from 10 to more than 50 μg.m-3), atmospheric particles (PM10) have potential damaging effects on the Public Health. Hence, the development of measures dealing with fine particulate matter is considered a priority by the EU Clean Air For Europe (CAFE) Program. Still, the origin of these airborne particles is subject to debate, as classical chemical methods showed their limitations. Recent studies have shown that stable isotopes of elements such as carbon, nitrogen or lead could be of great help in the search of new particle air pollution tracking tools. We will present here preliminary results on the pioneer use of stable isotope compositions of cadmium, zinc and mercury to help decipher the different possible origins of PM10 pollution in the atmosphere of Paris (France). Main potential sources were characterized: (1) waste incineration, (2) road traffic, (3) central heating and (4) coal-fired power plants. Results show that the use of cadmium (d114Cd) and zinc (d66Zn) isotopes, and the combination of both provides a reliable and precise tool for discriminating the different families of particle vectors. The isotope systematic of mercury (d200Hg) is more difficult to apprehend due to the low levels encountered (mercury is mainly present under gaseous form, but is still observed at low concentrations in particles), but does show significant variations between the different sources. Daily cumulative air samples were taken on three different locations, covering different scenarios in Paris city: 1) background pollution in Paris, 2) under the plume of a major pollution source and 3) Paris vicinity. Corresponding chemical and isotope analyses help identify the main vectors for the three elements (Cd, Zn and Hg) considered as well as assess their respective contributions to the levels of pollution observed.

It has been common practice for decades, especially since the Convention on Biological Diversity was adopted in Rio (1992), to protect certain marine areas, and the possibilities and scope of such marine protection measures have been widely discussed. The Helsinki and Oslo-Paris Conventions for the protection of the marine environment, which are relevant for Germany, provide a framework for the establishment of marine protected areas. As early as 1993, the Helsinki Commission (HELCOM), in its Recommendation 15/5, decided to create a system of “Baltic Sea Protected Areas (BSPA)”, starting with 62 areas. More protected areas are being added to the system. The Oslo-Paris Commission (OSPARCOM), within the framework of the new 1998 Annex V of the Convention on the Protection and Conservation of the Ecosystems and Biological Diversity of the Maritime Area, has initiated the establishment of a system of protected areas in the North-East Atlantic under the guidance of Germany. Information on the current status of both marine environmental protection systems is provided in this paper.

Hearing Pygmalion's Kiss: A Scientific Object at the Paris Opéra

NASA Astrophysics Data System (ADS)

Lambert, Kevin

2014-12-01

In 1748, in his acte de ballet Pygmalion, composer and music theorist Jean-Philippe Rameau arranged the Paris Opéra orchestra to play "nature's chord," harmonies that reproduced the overtones an expert ear could detect in every natural musical vibrating body. The following year Rameau presented his music theory to the French Royal Academy of Sciences for their endorsement. Disillusionment with the promise of Cartesian mechanics as a source of a unified understanding of nature opened up the possibility that matter might have properties beyond extension and motion, such as aversion, desire, and memory. Speculations about this material sensibility also coincided with increasing claims about the authority of spontaneous emotion and feeling. The experience of music at the opera was a significant resource for claims about the cultural authority of sensibility.

At the Paris Descartes medicine faculty, we tested some newly developed tools to enhance the pedagogic value of the pathology teaching. In our faculty, this teaching is largely multidisciplinary and integrated in various teaching units; a large part is dedicated to practice works with thirteen 90min sessions. Virtual slides have been used for years in numerous medicine faculties; we successfully implemented this tool by adding contextual annotations, which facilitate students revising. We showed that rewarding students' assiduity enhanced their exam success. To do so, we now propose a short continuous assessment exam at the beginning of each practice session in the form of electronic multi-choice questions. Finally, we now propose a completely computerized final exam, on touchpads, that enhanced its docimologic value. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

As the most famous woman scientist of the twentieth century, there has been no shortage of books and articles on the life and career of Marie Curie (1867-1934). Her role as director of a laboratory-based research school in the new scientific field of radioactivity, a field which embraced both chemistry and physics, however, has never been examined. In recent years, there has been a growing interest in the question of research schools, and Morrell, Ravetz, Geison, and Klosterman, amongst others, have written on this subject. Using, in part, the methodology of Morrell, this paper investigates the role of Marie Curie as a school director in the Paris Faculty in the years 1907-14, examining the work and characteristics of her school and assessing her effectiveness as a director.

Comparison between the atmospheric boundary layer in Paris and its rural suburbs during the ECLAP experiment

NASA Astrophysics Data System (ADS)

Dupont, E.; Menut, L.; Carissimo, B.; Pelon, J.; Flamant, P.

The ECLAP experiment has been performed during the winter of 1995 in order to study the influence of the urban area of Paris on the vertical structure and diurnal evolution of the atmospheric boundary layer, in situations favourable to intense urban heat island and pollution increase. One urban site and one rural site have been instrumented with sodars, lidars and surface measurements. Additional radiosondes, 100 m masts and Eiffel Tower data were also collected. This paper gives a general overview of this experiment, and presents results of the analysis of four selected days, characterized by various wind directions and temperature inversion strengths. This analysis, which consists in a comparison between data obtained in the two sites, has been focused on three parameters of importance to the ABL dynamics: the standard deviation of vertical velocity, the surface sensible heat flux, and the boundary layer height. The vertical component of turbulence is shown to be enhanced by the urban area, the amplitude of this effect strongly depending on the meteorological situation. The sensible heat flux in Paris is generally found larger than in the rural suburbs. The most frequent differences range from 25-65 W m -2, corresponding to relative differences of 20-60%. The difference of unstable boundary layer height between both sites are most of the time less than 100 m. However, sodar and temperature data show that the urban influence is enhanced during night-time and transitions between stable and unstable regimes.

While home-based chemotherapy improves comfort and quality of life of patients, quality and safety conditions must be equivalent to hospital settings. In addition, organization is much more complex. At the hospital at home "Assistance publique-Hôpitaux de Paris", prescribers are potentially spread across 21 health facilities. The administration of chemotherapy is performed by about 300 nurses at the patient's home in Paris and its suburbs. Centralized preparations of chemotherapy began in September 2009 by the pharmacy department of Georges-Pompidou European hospital, with a progressive increase of the activity. This article describes the quality insurance system established with this new organization to meet the specific challenges of home therapy: choice of eligible anticancer drugs, computerized information systems and networking with other heath facilities, secure transport conditions, traceability from the prescription to the administration, security of administration. This experience can offer an important support for other centres in their approach of quality insurance for home chemotherapy.

Perrussel3, B. Languille4 At the beginning of the 21st century air pollution in Paris continued to considerably decrease. An evident visual consequence was the replacement of thick gypseous black crusts by thin grey coverings on the façades. A quantitative approach of this phenomenon was taken by measurement in the field, followed by calculation using Dose-Response Functions (DRF) and mapping the geographic distribution on a grid of 100m x100m of: 1) The total surface of façades of buildings and monuments in the part of Paris inscribed on the UNESCO List between the Ile Saint-Louis and the Concorde Square; 2) The surface of limestone and window glass present on each façade; 3) The distribution of SO2, NO2 and PM10 concentration every year from 1997 to 2014; 4) The response of materials to climatic and pollution doses; 5) The effective damage to limestone and window glass. Results of measurements in the field: 1) The 772 buildings and monuments inventoried have 20 674 m in length and 414 811 m2 in façade surface: they are representative of the centre of Paris; 2) Limestone occupies 348 268 m2 and window glass 207 394 m2; 3) The mean annual concentration in SO2 dropped from 20 to less than 3 μg m-3; NO2 from 60 to 40 μg m-3 and PM10 from 30 to 20 μg m-3. Results by application of DRF: 4) Limestone recession was divided by 5 in 18 years, from 10 to 2 μm y-1, but with only a spatial variation of 2%; 5) Limestone reflectance increased from 70.5 to 72.5 %; 6) The annual mass of deposited and neo-formed particles on window glass decreased from 100 to 20 μg cm-2; 7) The annual haze of window glass decreased from 8 to 3.5%. Effective damage to stone and glass: 8) The mean annual mass of limestone eroded on the façades decreased according to time but with an irregular

The French public-private partnerships known as "competitive clusters" [pôles de compétitivité (PdC)] are intended to be novel and ambitious engines of regional growth, employment and biomedical innovation. Partly funded by government and local councils, they aim to capitalize on regional expertise by bringing together basic scientists, clinicians, innovative entrepreneurs and local decision-makers around specific themes that have become too costly and complex for any of these actors to tackle alone. Clusters provide the critical mass required both to underpin innovation potential and to authenticate regional claims to international competitiveness. Medicen is a biomedicine and therapeutics cluster comprising 120 partners from four broad "colleges" in the greater Paris region: major industry, small and medium-sized businesses, teaching hospitals/State research bodies, and local councils. Chief among its cooperative R&D projects is the neuroscience subcluster, in which "TransAl" the neurodegenerative disease project, counts Sanofi-Aventis, Servier and the French Atomic Energy Commission [Commissariat à l'Energie Atomique (CEA)] as key partners. One main aim is to develop an experimental model in rhesus monkeys in which a putative cause of Alzheimer's disease, intracerebral accumulation of b-amyloid peptide, is generated by impairing the peptide's clearance. The other aim, in which the nuclear medicine expertise of the CEA will be crucial, is to identify, characterize and validate markers for magnetic resonance and positron emission tomography imaging, and to source biomarkers from cerebrospinal fluid proteomics. A human biological resource centre (DNA and tissue banks) project dedicated to neurological and psychiatric disease should be up and running in 2007. Only through fundamental restructuring of resources on such a large cooperative scale are solutions likely to be found to the major problems of modern medicine, bringing healthcare and regional

Urban metabolism and river systems: an historical perspective - Paris and the Seine, 1790-1970

Barles, S.

2007-06-01

The aim of this paper is to analyse interaction between Paris and the Seine during the industrial era, 1790-1970, a period marked by strong population growth, changes in techniques, and the absence of specific legislation on environmental issues. The viewpoint focuses on exchanges of waters and wastes between city and river, quantifying them and tracing evolution in the light of the strategies implemented by the stakeholders in charge. The study combines industrial ecology, local history and the history of technology. From 1790 to 1850, waste matters, and especially excreta, were considered as raw materials, not refuse: they generated real profits. The removal of human excreta aimed not only at improving urban hygiene, but at producing the fertilizers needed in rural areas. Discharging them into the river was out of the question. But after the 1860s, several factors upset this exploitation, notably domestic water supply. Even so, Parisian engineers continued to process sewage using techniques that would not only ensure hygiene but also conciliate economic and agricultural interests. Both of these early periods are thus noteworthy for a relative limitation of the river's deterioration by urban wastes. Not until the 1920s, when domestic water supply had become the rule and excreta came to be considered as worthless waste, was the principle of valorisation abandoned. This led to important and long-lasting pollution of the Seine, aggravating the industrial pollution that had been in evidence since the 1840s. Analysing the priorities that led to the adoption of one principle or another in matters of urban hygiene and techniques, with the causes and consequences of such changes, enables us to understand the complex relations between Paris and the Seine. From raw material to waste matter, from river to drain, the concept of quality in environment remains the underlying theme.

The Paris terrorist attacks on 13 November 2015 caused 482 casualties, including 130 deaths and 352 wounded. Facing these multisite terrorist attacks, Parisian public and military hospitals simultaneously managed numerous patients with penetrating thoracic injuries. The aim of this study was to analyse this cohort, the injury patterns, and assess the results of this mobilization. The clinical records of all patients admitted to Parisian public and military hospitals with a penetrating thoracic injury related to the Paris 13 November terrorist attacks were reviewed. The study group included 25 patients (7% of the casualties) with a mean age of 34 ± 8 years and a majority of gunshot wounds ( n =  20, 80%). Most patients presented with severe thoracic injury (Abbreviated Injury Score Thorax 3.3 ± 1.2), and also associated non-thoracic injuries in 21 cases (84%). The mean Injury Severity Score was 26.8 ± 9.4. Eight patients (32%) were managed with chest tube insertion and 17 (68%) required thoracic surgery. Lung resection, diaphragmatic repair, and lung suture were performed in 6 (36%), 6 (35%), and 5 cases (29%), respectively. Extra-thoracic surgical procedures were performed in 16 patients, mostly for injuries to the extremities. Postoperative mortality was 12% ( n =  3) and postoperative morbidity was 60% ( n =  15). The coordination of Parisian military and civilian hospitals allowed the surgical management of 25 patients. The mortality is high but consistent with what has been reported in previous series. The current times expose us to the threat of new terrorist attacks and require that the medical community be prepared. © The Author 2017.

Long distance running races are associated with a low risk of life-threatening events much often attributed to hypertrophic cardiomyopathy. However, retrospective analyses of aetiology lack consistency. Incidence and aetiology of life-threatening/fatal events were assessed in long distance races in the prospective Registre des Accidents Cardiaques lors des courses d'Endurance (RACE Paris Registry) from October 2006 to September 2012. Characteristics of life-threatening/fatal events were analysed by interviewing survivors and reviewing medical records including post-mortem data of each case. Seventeen life-threatening events were identified of 511 880 runners of which two were fatal. The vast majority were cardiovascular events (13/17) occurring in experienced male runners [mean (±SD) age 43 ± 10 years], with infrequent cardiovascular risk factors, atypical warning symptoms prior to the race or negative treadmill test when performed. Acute myocardial ischaemia was the predominant aetiology (8 of 13) and led to immediate myocardial revascularization. All cases with initial shockable rhythm survived. There was no difference in event rate according to marathons vs. half-marathons and events were clustered at the end of the race. A meta-analysis of all available studies including the RACE Paris registry (n = 6) demonstrated a low prevalence of life-threatening events (0.75/100 000) and that presentation with non-shockable rhythm [OR = 29.9; 95% CI (4.0-222.5), P = 0.001] or non-ischaemic aetiology [OR = 6.4; 95% CI (1.4-28.8), P = 0.015] were associated with case-fatality. Life-threatening/fatal events during long distance races are rare, most often unpredictable and mainly due to acute myocardial ischaemia. Presentation with non-shockable rhythm and non-ischaemic aetiology are the major determinant of case fatality. Published on behalf of the European Society of Cardiology.

The distribution of the Rapid Antigen Detection Test (RADT) and the National Health Insurance's information campaign should efficiently reduce the unjustified use antibiotic. However, a preliminary survey among GP trainers at the Paris Descartes University indicated that the RADT was seldom used. This study had for aim to describe the RADT use trend among trainers since 2005 and the main obstacles to its widespread use, and to assess the Mac Isaac score use and antibiotic prescriptions. Between February and May 2007, a survey was carried out among 66 GPs who were required to report their first ten patients over three years of age presenting with pharyngitis. RADT use and antibiotic prescriptions were compared with those of the 2005 survey. RADT use had decreased (52.5% [48.2-56.8] versus 57.5% [52.1-68.8], p<0.05). GPs did not use the RADT because they considered it "useless in decision making". Clinical findings were sufficient in most cases. The Mac Isaac score was not widely used by GPs (28.3%) and antibiotic prescription had increased except for macrolides which had decreased (10% vs 15%). Among patients with a negative RADT, 11.9% (vs 10.5% en 2005, p<0.001) were prescribed antibiotics. The RADT use decreased in two years among GP trainers. GPs still prescribe treatment according to clinical findings, most without using diagnostic tools.

Towards the end of my time at Trousseau, it was a huge honour to be asked if I would like to consider staying on as an observer until October, with a view to continuing on, after that, in a Chef de Clinique appointment. This was a golden opportunity that I would have dearly snapped up. Unfortunately, the timing clashed with other previously made, very solid, arrangements. I am tremendously grateful to The Journal of Laryngology & Otology for supporting this Fellowship, and also to Professor Garabedian and his team for their exceptional hospitality, approachability and generosity. I have made some excellent friends in Paris. Overall, this was an extremely positive and valuable experience both in terms of family and work.

The objectives were to estimate the size of homeless family population in Paris region, to describe their living conditions and health and to analyse the impact of homelessness on children's growth and development, which was never investigated in France. A cross-sectional survey was conducted on a random sample of homeless sheltered families in 2013. Families were interviewed in 17 languages and a nurse took anthropometric measures, blood samples and collected health data from child health reports. The population size was estimated at 10 280 families. Half were single-parent female families and 94% were born outside France. Most families had experienced housing instability and 94% were living below the poverty line (828 euros/month). Malnutrition was a major problem: the prevalence of food insecurity was high (77% of parents and 69% of children), as well as anaemia (50% of mothers and 38% of children), overweight (38% of mothers and 22% of children) and obesity (32% of mothers and 4% of children). High rates of depressive disorders were found in 30% of homeless mothers and 20% of children had signs of possible mental health disorders. These first results highlight the important number of families among the homeless population in Paris region. Families differed from other homeless people regarding social characteristics such as birthplace, single-parent status and residential instability that are likely to influence schooling, social ties, health and access to care. These results demonstrate the need for urgent actions targeting homeless families, in terms of reducing housing instability and providing adequate care, especially for children. © The Author 2015.

An Astronomer In The Classroom: Observatoire de Paris's Partnership Between Teachers and Astronomers

NASA Astrophysics Data System (ADS)

Doressoundiram, A.; Barban, C.

2006-08-01

The Observatoire de Paris is offering a partnership between teachers and astronomers. The principle is simple: any teacher wishing to undertake a pedagogical project in astronomy, in the classroom or involving the entire school, can request the help of a mentor. An astronomer from the Observatoire de Paris will then follow the teacher's project progress and offer advice and scientific support throughout the school year. The projects may take different forms: construction projects (models, instruments), lectures, posters, exhibitions, etc. The type of assistance offered is as varied as the projects: lecture(s) in class, telephone and e-mail exchanges, visits to the Observatoire; an almost made-to-measure approach that delighted the thirty or so groups that benefited such partnership in the 2005-2006 academic year. And this number is continuously growing. There was a rich variety of projects undertaken, from mounting a show and building a solar clock to visiting a high altitude observatory, or resolving the mystery of Jupiter's great red spot. The Universe and its mysteries fascinate the young (and the not so- young) and provide a multitude of scientific topics that can be exploited in class. Astronomy offers the added advantage of being a multidisciplinary field. Thus, if most projects are generally initiated by a motivated teacher, they are often taken over by teachers in other subjects: Life and Earth Sciences (SVT), history, mathematics, French, and so forth. The project may consist in an astronomy workshop or be part of the school curriculum. Whatever the case, the astronomer's task is not to replace the teacher or the textbooks, but to propose activities or experiments that are easy to implement. Representing the Solar system on a school-yard scale, for instance, is a perfect way to make youngsters realize that the Universe consists mostly of empty space. There is no shortage of topics, and the students' enthusiasm, seldom absent, is the best reward for the

Features caused by ground ice growth and decay in Late Pleistocene fluvial deposits, Paris Basin, France

2018-06-01

Last Glacial fluvial sequences in the Paris Basin show laminated lacustrine deposits OSL and radiocarbon dated to between 24.6 and 16.6 ka in one site and overlying alluvial sandy gravel. A thermokarst origin of the lakes is supported by abundant traces of ground ice, particularly ice wedge pseudomorphs beneath the lacustrine layers and synsedimentary deformation caused by thaw settlement. The features include brittle deformation (normal and reverse faults) resulting from ground subsidence owing to ice melting and ductile deformations caused by slumping of the sediments heaved by the growth of ice-cored mounds. These correspond to lithalsas (or lithalsa plateaus) and/or to open system pingos. At least two generations of thermokarst are recorded and may reflect the millennial climate variability typical of the Last Glacial. The structures studied in quarries are associated with an undulating topography visible in 5-m DEMs and a spotted pattern in aerial photographs. The search for similar patterns in the Paris Basin indicates that many other potential thermokarst sites exist in the Last Glacial terrace (Fy) of rivers located north of 48°N when they cross the lower Cretaceous sands and marls. In some sites, the presence of organic-poor, fine-grained deposits presumably of lacustrine origin was confirmed by borehole data. The site distribution coincides broadly with that already known for ice wedge pseudomorphs. This study provides new evidence of permafrost-induced ground deformations in France and strongly suggests that thermokarst played a significant and probably largely underestimated role in the genesis of Late Pleistocene landscapes.

To find out the utility of The Paris System (TPS) in reporting urine cytology and to compare it with the reporting system currently used in our laboratory. This retrospective study was undertaken over a period of 1 year during which slides of all the urine specimens sent for cytological examination were retrieved from our laboratory filling system. They were blindly reviewed and reclassified according to TPS. Surgical follow-up was obtained from the uropathology services of our department. A total of 176 cases were meticulously reviewed. The mean age of the patients was 52 years, and 71% of cases presented with hematuria. Histopathological follow-up was available in 34 cases. Reporting by TPS detected 13.0% high-grade urothelial carcinoma (HGUC) and 5.1% atypical urothelial cells versus 7.3 and 11.9% by the current reporting system, respectively. The sensitivity and diagnostic accuracy for detecting HGUC of TPS were higher than those of our reporting system. TPS has increased the rate of detection of HGUC and reduced the rate of reporting "atypical" urothelial cells. TPS has also standardized the diagnostic criteria, thereby bringing uniformity and reproducibility into the system of reporting for urine cytology. © 2017 S. Karger AG, Basel.

Air pollution and respiratory hospital admissions in greater Paris: exploring sex differences.

PubMed

Granados-Canal, D J; Chardon, B; Lefranc, A; Gremy, I

2005-01-01

The subject of sex and gender differences is relevant to the study of health effects of environmental exposures. In this study the authors aim at assessing the differences that may exist between males and females regarding short-term air pollution health effects. They studied the short-term relationships between air pollution levels and respiratory hospital admissions in greater Paris area for patients older than 15 years between 2000 and 2003. They also conducted time series analyses by using generalized additive models. For an increase of 10 microg/m3 in the air pollutant levels, the increase in relative risk of hospitalization was higher for males than for females and was significant only for males. These differences may not result solely from differences in biological susceptibility to air pollution because other factors related to gender (differences in individual exposures, in health care management, and so on) may play a role.

Four new furostanol saponins, named padelaosides C-F (1-4), together with four known spirostanol saponins 5-8 were isolated from the rhizomes of Paris delavayi Franchet. Their structures were elucidated on the basis of extensive spectroscopic analysis and chemical evidences. The discovery of the new compounds 1-4 extended the diversity and complexity of this furostanol saponin family. The cytotoxicity of all the saponins was evaluated for their cytotoxicity against human glioblastoma U87MG and human hepatocellular carcinoma Hep-G2 cell lines. The known spirostanol saponins 7 and 8 exhibited notable cytotoxicity against the two tumor cell lines with IC50 values of 1.13 and 3.42μM, respectively, while the new furostanol saponins 3 and 4 showed moderate cytotoxicity with IC50 values of 15.28 to 16.98μM.

Europe's firs Hemalog D was installed in the Hematology Laboratory of the Franco-Musulman Hospital at Bobigny, just outside Paris, in March 1975. The authors' experience with the apparatus since that date has enabled them to analyze the significance of "alarms", "high peroxidase", "large unstained cells", "remainder" and "low rate" in patients with and without hematologic disorders. On the basis of these results it has been possible to define the fate of the various blood cells in the Hemalog D, the role of the apparatus in the ivestigation of hematologic disorders and the type of "cooperation" between the hematologist and the Hemalog D.

The Paris Agreement zero-emissions goal is not always consistent with the 1.5 °C and 2 °C temperature targets

NASA Astrophysics Data System (ADS)

Tanaka, Katsumasa; O'Neill, Brian C.

2018-04-01

The Paris Agreement stipulates that global warming be stabilized at well below 2 °C above pre-industrial levels, with aims to further constrain this warming to 1.5 °C. However, it also calls for reducing net anthropogenic greenhouse gas (GHG) emissions to zero during the second half of this century. Here, we use a reduced-form integrated assessment model to examine the consistency between temperature- and emission-based targets. We find that net zero GHG emissions are not necessarily required to remain below 1.5 °C or 2 °C, assuming either target can be achieved without overshoot. With overshoot, however, the emissions goal is consistent with the temperature targets, and substantial negative emissions are associated with reducing warming after it peaks. Temperature targets are put at risk by late achievement of emissions goals and the use of some GHG emission metrics. Refinement of Paris Agreement emissions goals should include a focus on net zero CO2—not GHG—emissions, achieved early in the second half of the century.

The indissociable unity of psyche and soma: a view from the Paris Psychosomatic School.

Aisenstein, Marilia

2006-06-01

Depending on whether or not psyche/soma is seen as singular or dual, one may construct different systems explaining man and the world, life and death. In the author's view, the discoveries of psychoanalysis offer a perfectly cogent and unique solution to the famous mind/body problem. In transferring the duality psyche/soma on to the duality of drives, psychoanalysis places the origin of the thought process in the body. In Beyond the pleasure principle, Freud discusses the drastic effect of a painful somatic illness on the distribution and modalities of the libido. He provides a starting point for the Paris Psychosomatic School's psychoanalytical approach to patients afflicted with somatic illnesses. To illustrate the technical implications of this theory the author relates two clinical cases.

Quantitative determination of carbonaceous particle mixing state in Paris using single particle mass spectrometer and aerosol mass spectrometer measurements

Single particle mixing state information can be a powerful tool for assessing the relative impact of local and regional sources of ambient particulate matter in urban environments. However, quantitative mixing state data are challenging to obtain using single particle mass spectrometers. In this study, the quantitative chemical composition of carbonaceous single particles has been estimated using an aerosol time-of-flight mass spectrometer (ATOFMS) as part of the MEGAPOLI 2010 winter campaign in Paris, France. Relative peak areas of marker ions for elemental carbon (EC), organic aerosol (OA), ammonium, nitrate, sulphate and potassium were compared with concurrent measurements from an Aerodyne high resolution time-of-flight aerosol mass spectrometer (HR-ToF-AMS), a thermal/optical OCEC analyser and a particle into liquid sampler coupled with ion chromatography (PILS-IC). ATOFMS-derived mass concentrations reproduced the variability of these species well (R2 = 0.67-0.78), and ten discrete mixing states for carbonaceous particles were identified and quantified. Potassium content was used to identify particles associated with biomass combustion. The chemical mixing state of HR-ToF-AMS organic aerosol factors, resolved using positive matrix factorization, was also investigated through comparison with the ATOFMS dataset. The results indicate that hydrocarbon-like OA (HOA) detected in Paris is associated with two EC-rich mixing states which differ in their relative sulphate content, while fresh biomass burning OA (BBOA) is associated with two mixing states which differ significantly in their OA/EC ratios. Aged biomass burning OA (OOA2-BBOA) was found to be significantly internally mixed with nitrate, while secondary, oxidized OA (OOA) was associated with five particle mixing states, each exhibiting different relative secondary inorganic ion content. Externally mixed secondary organic aerosol was not observed. These findings demonstrate the heterogeneity of primary and

Despite evidence of benefit for pharmacist involvement in chronic disease management, the provision of these services in community pharmacy has been suboptimal. The Promoting Action on Research Implementation in Health Services (PARiHS) framework suggests that for knowledge translation to be effective, there must be evidence of benefit, a context conducive to implementation, and facilitation to support uptake. We hypothesize that while the evidence and context components of this framework are satisfied, that uptake into practice has been insufficient because of a lack of facilitation. This protocol describes the rationale and methods of a feasibility study to test a facilitated pharmacy practice intervention based on the PARiHS framework, to assist community pharmacists in increasing the number of formal and documented medication management services completed for patients with diabetes, dyslipidemia, and hypertension. A cluster-randomized before-after design will compare ten pharmacies from within a single organization, with the unit of randomization being the pharmacy. Pharmacies will be randomized to facilitated intervention based on the PARiHS framework or usual practice. The Alberta Context Tool will be used to establish the context of practice in each pharmacy. Pharmacies randomized to the intervention will receive task-focused facilitation from an external facilitator, with the goal of developing alternative team processes to allow the greater provision of medication management services for patients with diabetes, hypertension, and dyslipidemia. The primary outcome will be a process evaluation of the needs of community pharmacies to provide more clinical services, the acceptability and uptake of modifications made, and the willingness of pharmacies to participate. Secondary outcomes will include the change in the number of formal and documented medication management services in the aforementioned chronic conditions provided 6 months before, versus after, the

Assessing the resilience of urban areas to traffic-related air pollution: Application in Greater Paris.

Recent studies report that outdoor air pollution will become the main environmental cause of premature death over the next few decades (OECD, 2012; WHO, 2014; World Bank, 2016). Cities are considered hot spots and urban populations are particularly exposed. There is therefore an urgent need to adapt urban systems and urban design to tackle this issue. While most European cities have introduced measures to reduce emissions, action is still required to reduce concentrations and exposure, and a holistic approach to urban design is badly needed. The concept of urban resilience, defined by Holling (1987) as the ability of a city to absorb a disturbance while maintaining its functions and structures, may offer a new paradigm for tackling urban air pollution. We propose to adapt the concept of urban resilience to outdoor air pollution. A method has been developed to assess the resilience of an urban area to outdoor air pollution. Three "resilience capacities" have been identified: the capacity of an urban area to decrease air pollution emissions, the capacity to decrease concentrations and the capacity to decrease exposure. The calculation is based on the analysis of urban design, defined as the pattern of buildings as well as the structural elements that define an urban area (urban morphology; transport network, services and land use). For each resilience capacity, indicators are calculated using a Geographic Information System (GIS) and a grid-based approach. This method has been implemented in the Greater Paris area within a 500m grid-cell system. Greater Paris is one of the densest urban areas in Europe and experiences high air pollution levels. The proposed "quick scan" method helps to localize areas where specific action is needed. Copyright © 2017 Elsevier B.V. All rights reserved.

Social suffering and anxiety: deciphering coughs and colds at Akan anti-witchcraft shrines in Paris.

Parish, Jane

2011-12-01

In treating illness and suffering, the Akan anti-witchcraft shrine is often presented as a model of unchanging, tightly bounded and antiquated ideals. This fails to acknowledge the extensive repertoire of Ghanaian witchcraft discourses and contemporary divinatory practices uncovered at Akan anti-witchcraft shrines. This paper analyses how one of the most popular Akan anti-witchcraft shrine in Europe, in an eastern banlieue of Paris, diagnoses the seemingly common and innocuous coughs and colds suffered by recently arrived, unskilled female Ghanaian migrants as something more socially and economically malignant, witchcraft. Successful treatment combines divinatory techniques, paracetamol medicines and positive thinking in order to empower clients and present them with the possibility of new social and gainful employment prospects.

The reticular hierarchical structure of butterfly wings (Papilio Paris) is introduced as template for Au/TiO(2) photocatalyst by depositing the Au nanoparticles on TiO(2) matrix, which is carried out by a water-ethanol sol-gel procedure combined with subsequent calcination. The obtained Au/TiO(2) nanocomposites present the reticular hierarchical structure of butterfly wings, and Au nanoparticles with an average size of 7 nm are homogeneously dispersed in TiO(2) substrate. Benefiting from such unique reticular hierarchical structure and composition, the biomorphic Au/TiO(2) exhibits high-harvesting capability and presents superior photocatalytic activity. Especially, the biomorphic Au/TiO(2) at the nominal content of gold to titanium of 8 wt% shows the highest photocatalytic activity and can completely decompose methyl orange within 80 min, which is obviously higher than that of commercial Degussa P25 powders.

In a growing world with more than 7 billion inhabitants and big emerging countries such as China, Brazil and India, emissions of anthropogenic pollutants are increasing continuously. Monitoring and control of atmospheric pollutants in megacities have become a major challenge for scientists and public health authorities in environmental research area. The QualAir platform at University Pierre et Marie Curie (UPMC), is an innovating experimental research platform dedicated to survey greenhouse gases (GHGs) and urban air quality. As one of the major instruments of the QualAir platform, the ground-based Fourier transform spectrometer (QualAir FTS, IFS 125HR model) analyses the composition of the urban atmosphere of Paris, which is the third European megacity. The continuous monitoring of atmospheric pollutants is essential to improve the understanding of urban air pollution processes. Associated with a sun-tracker, the QualAir remote sensing FTS operates in solar infrared absorption and enables to monitor many trace gases, and to follow up their variability in the Ile-de-France region. A description of the QualAir FTS will be given. Concentrations of atmospheric GHG, especially CO2 and CH4, are retrieved by the radiative transfer model PROFFIT. Located in the centre of Paris, the QualAir FTS can provide new and complementary urban measurements as compared to unpolluted ground-based stations of existing networks (NDACC and TCCON). The work made by LPMAA to join the TCCON network will also be presented. TCCON-Orléans is a ground-based FTS of the TCCON network located in the forest of Orléans (100 km south of Paris). Preliminary comparisons of GHGs measurements from both sites will be shown. Such ground-based information will help to better characterize regional GHGs, especially regarding anthropogenic emissions and trends.

Joseph Gensoul was a pioneer of ENT surgery. In 1827, he performed the first total maxillectomy on 17-year-old boy. His work inspired many surgeons, who were previously unwilling to remove maxillary tumours. A paleopathological study performed in the Dupuytren museum allowed us to identify a skull from the early 19th century, with a large maxillar tumour. There were indications that this skull was operated according to Gensoul's technique. The aim of this study is to confirm that this patient had, in fact, received this surgical treatment. This is a historical and descriptive paleopathological study of a skull of the early 19th century of Dupuytren Museum in Paris. The historical research was conducted in collaboration with the French Academy of Medicine and the Museum of Medicine History (Paris). Bones mark cut studies allowed us to confirm that the patient was operated according to the method described by Gensoul in his "Surgical letter" in 1833. Our historical research has allowed us to understand the perspectives of surgeons in the 19th century and the intellectual processes that led to this discovery. At a time when the robotization and industrialization dominate our art, it is interesting to look to our past, our origins, and our history. The study of ancient humans remains and allows us to understand the origin of our specialty and pay tribute to these pioneering surgeons. Their intellectual approach and boldness should be acknowledged and applauded, especially as it is also the key to our success.

Little is known about the prevalence of cervical cancer screening (CCS) and its correlates among homeless women in France. The objectives of this study were to determine the prevalence of women who had never been screened for cervical cancer and to identify the associated factors. This cross-sectional study was based on data collected in the ENFAMS survey, which was conducted in 2013 among 764 sheltered homeless mothers in the Greater Paris Area. Robust Poisson regression models were used to estimate the association between no lifetime CCS and certain sociodemographic and health-related factors (selected from the behavioral model of vulnerable populations). Analyses were carried out separately for women with and without a regular gynaecological follow-up (RGF). The proportion of never-screeners was 33% among the women with an RGF versus 64% among those without an RGF (P<0.001). Among the latter, never having been screened for CCS was associated mainly with socioeconomic conditions, the length of time lived in France, a history of delivery in France and the duration of homelessness. In those with an RGF, the factors were mainly poor health service utilization and language difficulties. This first quantitative study of CCS among homeless women in the Greater Paris Area points to the need for it to be proposed and performed more systematically in primary care. Every contact between this hard-to-reach population and health services should be an opportunity to check their screening status and to ensure that those in need actually undergo a Pap test.

In massive catastrophic events, occupational health practitioners are more and more frequently involved in the management of such situations. We aim to describe the multiple aspects of the role that occupational health practitioners might play, by focusing on the recent example of the Paris terrorist attack of November 2015. During and after the Paris attack, occupational practitioners, in collaboration with emergency and security professionals, were involved in psychological care, assembling information, follow-up, return-to-work, and improving in-company safety plans. Based on this experience and other industrial disasters, we distinguish three phases: the critical phase, the post-critical phase, and the anticipation phase. In the critical phase, the occupational practitioner cares for patients before the emergency professionals take charge, initiates the psychological management, and may also play an organizational role for company health aspects. In the post-critical phase, he or she would be involved in monitoring those affected by the events and participate in preventing, to the extent possible, posttraumatic stress disorder, helping victims in the return-to-work process, and improving procedures and organizing drills. In addition to their usual work of primary prevention, occupational practitioners should endeavor to improve preparedness in the anticipation phase, by taking part in contingency planning, training in first aid, and defining immediately applicable protocols. In conclusion, recent events have highlighted the essential role of occupational health services in anticipation of a crisis, management during the crisis, and follow-up.

To provide the basic guidance for seed breeding and cross-breeding of Paris polyphylla var. yunnanensis. The floral behavior and pollinators were observed; 0.5% TTC solution was used for the pollen viability test and benzidine and -H2O2 was used for estimation of the stigma receptivity. The mating systems were tested by out crossing index (OC1), and pollination experiment was carried out by bagged and emasculated test in the field. Commonly, stigma lobes spread slightly, and anthers started presenting the pollen from the outer ring while the flower was just beginning to open. Consequently, the distance between the stigma and its own pollen was relatively far, this "floral behavior" may be conducive to outcrossing. Then the flower entered the later period, while the stigma lobes spread widely, anthers all split, and this "floral behavior" shortened the stigma and its own pollen's distance, which may be conducive to selfing. P. polyphylla was partly protogynous. Stigma life-span was about 10-12 d. After anther dehiscence, the pollen viability maintained about 10% within 2 days, and 20% within 10 days. The value of out crossing index (OC1) was 4. By pollination experiment and pollinators observed, P. polyphylla was self-compatible, but no capacity for autonomous self-fertilization; In natural circumstances, outcrossing fructification rate was low, and mainly anemophilous. Assisted selfing-fertilization fructification rate was higher, spider was the main pollinators. P. polyphylla has a mixed mating system with self-pollination and cross-pollination characteristics. Floral behavior has important adaptive significance in avoiding female and male interference, outcrossing, and delayed selfing. P. polyphylla is ambophily (a combination of both wind and insect pollination), pollinators changes due to environment. Pollen limitation is the main cause of low fructification rate under natural conditions.

Geological rally in the heart of Paris: How to find fossils in freestone buildings in Paris?

As a teacher in earth sciences, my challenge was to practise geology in an urban area. At the end of the school year, I organized a geological rally next to the Natural History Museum in the heart of Paris. The rally provided the opportunity to apply geological notions mentioned in class, and or a day out to my 16 years-old pupils. Just before this original session, students worked on different sedimentary stones such as limestone, sandstone, gypsum, and "meulière". They studied the conditions for the deposit of sediments and they identified different fossils (i.e: Cerithes, Nummulites, Milioles) in order to build "paleobackgrounds". This rally was a mean to improve with entertainment their knowledge in geology, and to discover the stones of the Parisian basin and their use as building materials. The rally was organized as follows: the pupils were divided into 4 teams of 8 students. Each team got a paper with 23 riddles. Each riddle led to a geological spot in the route of the rally. To attest their passing at each geological point the pupils had to take a picture of the characteristic fossil or the typical mark of each spot. Each team had a different itinerary to avoid pupils to meet during the rally. In order to motivate pupils and to ensure their safety, one teacher went with each team. Each riddle led to a stage. This rally comprised 23 steps which were geological spots. In case of pupils did not solve the enigma of one stage; they could open an envelope in which a map indicated the 23 geological spots. This rally lasted 2 hours. The purpose of this game was to obtain the most points thanks to the resolution of riddles. Timing and the quality of the pictures were also criterions used to evaluate the participants. At the end of this rally, pupils must be able to identify sedimentary stones, the conditions and the age of deposit of this stones (paleobackgrounds), the location of their extractions (carries), the interest of this stones in construction industry

Paul Tessier is widely regarded as the father of modern craniofacial surgery. Upon his passing in 2008, his private collection of human skulls was purchased by the French Association of Facial Surgeons to ensure the collection would remain in France. The first public exhibition of the skulls was held in the medical museum of the University of Paris Descartes in April 2014. From this collection of skulls and the imagination of Tessier an entirely new specialty was created. Modern craniofacial surgery, now is an integral part of any pediatric plastic surgery department. Cranial and facial osteotomies have also become commonplace in both traumatic and aesthetic surgery. The goals for craniofacial deformity are now a return to completely normal appearance and function, as Tessier always believed they should be.

Termites of the genus Reticulitermes are widespread invaders, particularly in urban habitats. Their cryptic and subterranean lifestyle makes them difficult to detect, and we know little about their colony dynamics over time. In this study we examined the persistence of Reticulitermes flavipes (Kollar) colonies in the city of Paris over a period of 15 years. The aim was (1) to define the boundaries of colonies sampled within the same four areas over two sampling periods, (2) to determine whether the colonies identified during the first sampling period persisted to the second sampling period, and (3) to compare the results obtained when colonies were delineated using a standard population genetic approach versus a Bayesian clustering method that combined both spatial and genetic information. Herein, colony delineations were inferred from genetic differences at nine microsatellite loci and one mitochondrial locus. Four of the 18 identified colonies did not show significant differences in their genotype distributions between the two sampling periods. While allelic richness was low, making it hard to reliably distinguish colony family type, most colonies appeared to retain the same breeding structure over time. These large and expansive colonies showed an important ability to fuse (39% were mixed-family colonies), contained hundreds of reproductives and displayed evidence of isolation-by-distance, suggesting budding dispersal. These traits, which favor colony persistence over time, present a challenge for pest control efforts, which apply treatment locally. The other colonies showed significant differences, but we cannot exclude the possibility that their genotype distributions simply changed over time.

Atmospheric concentration measurements are used to adjust the daily to monthly budget of fossil fuel CO2 emissions of the Paris urban area from the prior estimates established by the Airparif local air quality agency. Five atmospheric monitoring sites are available, including one at the top of the Eiffel Tower. The atmospheric inversion is based on a Bayesian approach, and relies on an atmospheric transport model with a spatial resolution of 2 km with boundary conditions from a global coarse grid transport model. The inversion adjusts prior knowledge about the anthropogenic and biogenic CO2 fluxes from the Airparif inventory and an ecosystem model, respectively, with corrections at a temporal resolution of 6 h, while keeping the spatial distribution from the emission inventory. These corrections are based on assumptions regarding the temporal autocorrelation of prior emissions uncertainties within the daily cycle, and from day to day. The comparison of the measurements against the atmospheric transport simulation driven by the a priori CO2 surface fluxes shows significant differences upwind of the Paris urban area, which suggests a large and uncertain contribution from distant sources and sinks to the CO2 concentration variability. This contribution advocates that the inversion should aim at minimising model-data misfits in upwind-downwind gradients rather than misfits in mole fractions at individual sites. Another conclusion of the direct model-measurement comparison is that the CO2 variability at the top of the Eiffel Tower is large and poorly represented by the model for most wind speeds and directions. The model's inability to reproduce the CO2 variability at the heart of the city makes such measurements ill-suited for the inversion. This and the need to constrain the budgets for the whole city suggests the assimilation of upwind-downwind mole fraction gradients between sites at the edge of the urban area only. The inversion significantly improves the agreement

In 2013 Harris Corporation and Atmospheric and Environmental Research developed the GreenLITE™ system under a cooperative agreement with the Department of Energy, National Energy Technology Laboratory, to monitor geologic carbon storage sites on the square km scale. Since that time the system has expanded to enable coverage of areas >25 km2, and was deployed over the city of Paris, France, in November 2015. The system consists of two scanning continuous wave laser absorption spectroscopy instruments and a number of reflectors arranged to provide a number of overlapping 2-5 km chords across the 25 km2 area. The system was deployed as a demonstration for the 21st Conference of Parties (COP21), and has since been extended to a full year experiment. Operating GreenLITE for a full year will allow evaluations of seasonalvariability and enable ingestion of these measurements into inversion model frameworks to estimate the city'semissions. High resolution emissions models currently function on scales of 1-4 km2 and use in situ instrumentation located outside of the urban environment for the inversions due to challenges related to high spatio-temporal variability within the complex urban environment. GreenLITE measurements, on the other hand, provide integrated measurements on spatial and temporal scales that are more suitable for these models.This presentation will review the GreenLITE measurement approach and discuss results of the GreenLITE demonstration, including: comparisons with well calibrated Picarro and ThermoFisher in situ instruments located in or near the GreenLITE footprint, comparisons with high resolution model results, and recent steps toward using the GreenLITE data directly in the inversion models.

ETHOS is a pilot research project supported by the radiation protection research program of the European Commission (DG XII). The project provides an alternative approach to the rehabilitation of living conditions in the contaminated territories of the CIS in the post-accident context of Chernobyl. Initiated at the beginning of 1996, this 3-y project is currently being implemented in the Republic of Belarus. The ETHOS project involves an interdisciplinary team of European researchers from the following institutions: the Centre d'etude sur l'Evaluation de la Protection dans le domaine Nucleaire CEPN (radiological protection, economics), the Institute National d'Agronomie de Paris-Grignon INAPG (agronomy, nature & life management), the Compiegne University of Technology (technological and industrial safety, social trust), and the Mutadis Research Group (sociology, social risk management), which is in charge of the scientific co-ordination of the project. The Belarussian partners in the ETHOS project include the Ministry of Emergencies of Belarus as well as the various local authorities involved with the implementation site. The ETHOS project relies on a strong involvement of the local population in the rehabilitation process. Its main goal is to create conditions for the inhabitants of the contaminated territories to reconstruct their overall quality of life. This reconstruction deals with all the day-to-day aspects that have been affected or threatened by the contamination. The project aims at creating a dynamic process whereby acceptable living conditions can be rebuilt. Radiological security is developed in the ETHOS project as part of a general improvement in the quality of life. The approach does not dissociate the social and the technical dimensions of post-accident management. This is so as to avoid radiological risk assessment and management being reduced purely to a problem for scientific experts, from which local people are excluded, and to take into

The outbreak of influenza A(H1N1)pdm09 was a challenge for the laboratories of Paris Île-de-France region in charge of virological diagnosis. In order to evaluate the quality of their response to this challenge, a retrospective survey based on a self-administered standardized questionnaire was undertaken among the 18 hospital laboratories involved in A(H1N1)pdm09 virus detection over a period of 10 months from April 2009 to January 2010. All concerned laboratories responded to the survey. Due to imposed initial biosafety constraints and indications, virological diagnosis was performed in only two laboratories at the start of the studied period. Step by step, it was further settled in the other laboratories starting from June to November 2009. From the beginning, A(H1N1)pdm09-specific RT-PCR was considered the reference method while the use of rapid influenza detection tests remained temporary and concerned a minority of these laboratories. Among the overall 21,656 specimens received, a positive diagnosis of influenza A(H1N1)pdm09 was obtained in 5,390 cases (25%), the positivity range being significantly higher among women as compared to men (P<0.0001) and subjects below 45 years of age as compared to those over 65 years (P<0.0001). Two peaks in positivity frequency were observed at weeks 24 (30%, 8-12 June 2009) and 44 (50%, 26-30 October 2009) respectively, the latter one occurring 2 weeks earlier than the peak of epidemic at the national level. In contrast, a low positivity rate was detected at weeks 38-40 in relationship with other respiratory virus infections which were clinically misinterpreted as a peak of influenza epidemic. These data demonstrate the ability of medical virology laboratories of Paris Île-de-France region to provide in real time a valuable diagnosis of A(H1N1)pdm09 virus infection and a relevant view of outbreak evolution, suggesting they will be a crucial component in the management of future influenza epidemics.

The positive effect of early defibrillation on survival from cardiac arrest has been demonstrated. We describe the use of AEDs over 1 year following the training of flight attendants. Air France and the University of Paris XII together designed a 1 year training programme for 14000 flight attendants. The university emergency departments (SAMU) provided 250 instructors. AEDs training and certification was conducted for crew members between November 2001 and November 2002. By January 2003, all aircraft were fully equipped with AEDs. All cases of cardiac arrest that occurred during the study were reviewed comprehensively. Comments from the crew were collected. Twelve cardiac arrests were reported between November 2002 and November 2003 out of 4194 cases of emergency care delivered to passengers. Shock treatment was advised initially in 5/12 cases. The survival rate after in-flight cardiac arrest was 3/12. The survival rate at discharge from hospital following in flight shock was 2/5. No complications arose from the use of AEDs. Training by professionals gave the flight attendants confidence and allowed for the survival of two young passengers. Our study highlights the ability of flight attendants to give better onboard care for the future. The next step is to consolidate the network between in-flight care and the medical dispatch centre in Paris.

Establish the epidemiological characteristics and urinary toxicological profiles of a population of cocaine addicts under police custody. A series of 60 cocaine addicts consulting the medico-legal emergency unit of the Hôtel-Dieu hospital in Paris was studied prospectively on the following elements: clinical characteristics, method of cocaine administration and association with other licit or illicit substances. Urinary toxicological analysis, using immuno-chemistry and chromatography linked to a mass spectrometer was systematically proposed to each patient. Half of the 17 to 26 year-old patients declared having consumed cocaine for the past 2 to 5 years. Inhalation of the vapours and the intravenous route were used more than the cigarette or nasal route. The majority of 26 to 35 year-olds were multi-drug addicted, generally associating cocaine, heroine and tobacco. Analysis of the urine provided an objective assessment of the cocaine consumption of these persons under police custody in Paris. Screening for urinary toxicity gives better knowledge on the consumption of addictive products by the person in whom urine was sampled. This study was conducted in cocaine addicts under police custody, and for the majority were social misfits. In this population, the consumption of crack by inhalation predominated.

To analyze the results of the bibliometric system (SIGAPS score) of scientific publications in the Assistance publique-Hôpitaux de Paris (AP-HP) and to compare the scientific production among the various medical and surgical specialties of the academic hospitals of Paris. All the publications imported from Pubmed between 2006 and 2008 were included. The following data were taken into account and analysed: the hospital department of origin, the number of articles published, the number of full-time physicians, the SIGAPS score. Thirty-eight thousand, seven hundred and nine publications were included. The departments were consisted of 747 full-time practitioners 5719 (1895 Professors [33.1%], 2772 Assistant Professors [48.4%] and 1052 fellows [18.4%]). The average number of full-time practitioner by department was 7.7±6.7 (range 1-69). The average total number of articles published in a department was 51.8±49.4 (range 1-453). The average SIGAPS score was more important in medicine than in surgery (621.2±670.1 vs. 401±382.2; P=0.01) but not the average number of article per practitioner (8.1±8.3 vs. 6.6±6.2; P=0.0797). The mean number of publication by full-time practitioner was 7.9±7.8 (1-45), or an average of 2.7±2.6 for each full-time practitioner each year. Academic hospitals in Paris have a reasonably scientific output but with a mean of 2.7 articles per full-time practitioner per year. No major differences between medical and surgical disciplines were observed. Copyright © 2012 Société nationale française de médecine interne (SNFMI). Published by Elsevier SAS. All rights reserved.

Patients (N = 66) aged 15 years or older with severe TBI (Glasgow Coma Scale score of 8 or less) and their primary informal caregivers. Multicenter inception cohort study over 22 months in Paris and the surrounding area (PariS-TBI study). Patients' preinjury characteristics; injury severity data; outcome measures at discharge from intensive care and 1 year after the injury; Dysexecutive Questionnaire; Medical Outcome Study Short Form-36; Zarit Burden Inventory. Among the 257 survivors at discharge from acute care, 66 patient-caregiver couples were included. Primary informal caregivers were predominantly women (73%), of middle age (age, 50 years), supporting male patients (79%), of mean age of 38 years. The majority (56%) of caregivers experienced significant burden, and 44% were at risk of depression. Caregivers' impaired health status and perceived burden significantly correlated with patients' global disability (as assessed with the Glasgow Outcome Scale-Extended) and impairments of executive functions (as assessed with the Dysexecutive Questionnaire). A focused principal component analysis suggested that disability and executive dysfunctions were independent predictors of perceived burden, whereas demographics, injury severity, and Glasgow Outcome Scale at discharge from acute care did not significantly correlate with caregiver's burden. Global handicap and impairments of executive functions are independent significant predictors of caregiver burden 1 year after TBI.

We retrospectively studied daptomycin use during 2010 at the Bichat-Claude-Bernard teaching-hospital (Paris) to observe the evolution of daptomycin prescriptions. Twenty-one patients were included and several parameters were documented: site of infection, bacterial species involved, reason for daptomycin use, dose and clinical outcome. Ninety-five percent of daptomycin prescritions were off-label and most did not comply with local guidelines. Fifteen of the 21 patients were cured (71%), including 9 patients of the 12 with off-label and off-local recommendation prescriptions (75%). Osteitis and Enterococcus spp endocarditis were the new indications. Daptomycin was increasingly used at higher doses: 52% of our patients were given doses above 6mg/kg. Staphylococcus spp. was the most frequent pathogen responsible for infection is our patients, followed by Enterococcus spp. Daptomycin use is likely to evolve because of its effectiveness in the treatment of osteitis, left-sided and Enterococcus spp. infective endocarditis. It is generally used at higher doses, which are well tolerated. However, therapeutic monitoring needs to be developed. The antibiotic commission of our hospital gave new recommendations for daptomycin use in 2011. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

The meaning of city noises: Investigating sound quality in Paris (France)

Dubois, Daniele; Guastavino, Catherine; Maffiolo, Valerie; Guastavino, Catherine; Maffiolo, Valerie

2004-05-01

The sound quality of Paris (France) was investigated by using field inquiries in actual environments (open questionnaires) and using recordings under laboratory conditions (free-sorting tasks). Cognitive categories of soundscapes were inferred by means of psycholinguistic analyses of verbal data and of mathematical analyses of similarity judgments. Results show that auditory judgments mainly rely on source identification. The appraisal of urban noise therefore depends on the qualitative evaluation of noise sources. The salience of human sounds in public spaces has been demonstrated, in relation to pleasantness judgments: soundscapes with human presence tend to be perceived as more pleasant than soundscapes consisting solely of mechanical sounds. Furthermore, human sounds are qualitatively processed as indicators of human outdoor activities, such as open markets, pedestrian areas, and sidewalk cafe districts that reflect city life. In contrast, mechanical noises (mainly traffic noise) are commonly described in terms of physical properties (temporal structure, intensity) of a permanent background noise that also characterizes urban areas. This connotes considering both quantitative and qualitative descriptions to account for the diversity of cognitive interpretations of urban soundscapes, since subjective evaluations depend both on the meaning attributed to noise sources and on inherent properties of the acoustic signal.

The relationship between food insecurity and obesity is discussed in the literature. The objective of this study was to determine whether food insecurity and obesity were associated in the Paris metropolitan area. We used data from third wave of the Health, Inequalities and Social Ruptures (SIRS) cohort study, a longitudinal population-based, representative health and socioepidemiological survey of the general population in the Paris metropolitan area. The participants' BMI (calculated using self-reported height and weight) was analyzed as a continuous variable, and a dichotomous variable (BMI < 30 kg/m(2)/BMI ≥ 30 kg/m(2)) was constructed. Food insecurity was estimated using the Household Food Security Scale Module (HFSSM) and was treated as a trichotomous variable (food security / low food security / very low food security). Multilevel models were estimated for men and women separately. Obesity (BMI ≥ 30 kg/m(2)) prevalence was 10.2%. The determinant of obesity differs according to gender. After adjustment for age, income and the sociooccupational group, very low food security was associated with obesity in women (OR = 2.01, 95%CI 1.05-3.82), and women with very low food security had a higher BMI (Coef. = 1.78, 95% CI 0.24-3.31).

Chagas disease is endemic in Latin America (LA). Currently 10 million people are infected despite World Health Organization efforts aimed at preventing domestic transmission. However, with the migration of infected asymptomatic individuals to nonendemic countries, transmission of Chagas disease by transfusion may become a worldwide problem. The observation that the number of cases of Chagas disease has increased over the past 10 years in French Guiana, together with the results of a previous hospital-based study in the Paris area, confirms the transmission of Chagas disease from patients coming from LA. For these reasons, the French authorities stopped the collection of blood in French Guiana in 2005 and began screening blood donors in the French Caribbean islands and, in 2007, in continental France. Data on birth place, mother's birth place, and travel in LA were recorded for at-risk donors. These subjects were tested using two enzyme-linked immunosorbent assays (ELISAs). Of the 312,458 individuals who gave blood in the Paris area during an 18-month period, 30,837 were tested. Of these, 972 were born in LA, three of whom were positive for the two ELISAs and immunofluorescence tests. The prevalence of Trypanosoma cruzi-positive donors was 9.7 in 100,000 tested donors, but 0.31% among donors born in LA. Serology tests gave discrepant results in 1.02% of the samples. The efficiency of blood donor screening programs could be improved by screening only blood donors who were born in LA or who have traveled in LA for extended periods, using a single enzyme immunoassay.

Recent conflicts have allowed the French Army Health Service to improve management quality for wartime-injured people during military operations. On November 13, 2015, it was in Paris that France was directly attacked and Bégin Military Teaching Hospital, like several hospitals in Paris, had to face a large number of gunshot victims. Thanks to our operational experience, injured people hospitalized in military hospitals benefited from a management based on triage and damage control (DC) principles. Forty-five patients were taken care of in our hospital with an average age of 32 years. During triage, eight patients were categorized T1 (with four extreme emergencies) and 10 were classified T2 and 27 as T3. Twenty-two patients underwent emergency surgery, 15 for soft tissue lesions of limbs, 8 for ballistic fractures (one of which was a cervical wound), and 5 for abdominal wounds. Two patients classified T1 died early. In total, more than 50 operations were performed including iterative debridements, bone fixation, three amputations, and two flaps. After 9 months, all of the patients had healed. One woman with limb stiffness required an arthrolysis. This event showed that terrorist attacks and mass casualties with war wounds can occur in France. Acquired experience regarding war wounds by the French Army Health Service is precious. Everyone must understand the importance of triage and the principles of damage control. Every hospital must be ready to face this type of massive influx of injured people (white plan).

The purpose of this study was to examine the physiological and biomechanical changes occurring in a subject after running 8,500 km in 161 days (i.e. 52.8 km daily). Three weeks before, 3 weeks after (POST) and 5 months after (POST+5) running from Paris to Beijing, energy cost of running (Cr), knee flexor and extensor isokinetic strength and biomechanical parameters (using a treadmill dynamometer) at different velocities were assessed in an experienced ultra-runner. At POST, there was a tendency toward a 'smoother' running pattern, as shown by (a) a higher stride frequency and duty factor, and a reduced aerial time without a change in contact time, (b) a lower maximal vertical force and loading rate at impact and (c) a decrease in both potential and kinetic energy changes at each step. This was associated with a detrimental effect on Cr (+6.2%) and a loss of strength at all angular velocities for both knee flexors and extensors. At POST+5, the subject returned to his original running patterns at low but not at high speeds and maximal strength remained reduced at low angular velocities (i.e. at high levels of force). It is suggested that the running pattern changes observed in the present study were a strategy adopted by the subject to reduce the deleterious effects of long distance running. However, the running pattern changes could partly be linked to the decrease in maximal strength.

Most of the global fossil fuel CO2 emissions arise from urbanized and industrialized areas. Bottom-up inventories quantify them but with large uncertainties. In 2010-2011, the first atmospheric in situ CO2 measurement network for Paris, the capital of France, began operating with the aim of monitoring the regional atmospheric impact of the emissions coming from this megacity. Five stations sampled air along a northeast-southwest axis that corresponds to the direction of the dominant winds. Two stations are classified as rural (Traînou - TRN; Montgé-en-Goële - MON), two are peri-urban (Gonesse - GON; Gif-sur-Yvette - GIF) and one is urban (EIF, located on top of the Eiffel Tower). In this study, we analyze the diurnal, synoptic and seasonal variability of the in situ CO2 measurements over nearly 1 year (8 August 2010-13 July 2011). We compare these datasets with remote CO2 measurements made at Mace Head (MHD) on the Atlantic coast of Ireland and support our analysis with atmospheric boundary layer height (ABLH) observations made in the center of Paris and with both modeled and observed meteorological fields. The average hourly CO2 diurnal cycles observed at the regional stations are mostly driven by the CO2 biospheric cycle, the ABLH cycle and the proximity to urban CO2 emissions. Differences of several µmol mol-1 (ppm) can be observed from one regional site to the other. The more the site is surrounded by urban sources (mostly residential and commercial heating, and traffic), the more the CO2 concentration is elevated, as is the associated variability which reflects the variability of the urban sources. Furthermore, two sites with inlets high above ground level (EIF and TRN) show a phase shift of the CO2 diurnal cycle of a few hours compared to lower sites due to a strong coupling with the boundary layer diurnal cycle. As a consequence, the existence of a CO2 vertical gradient above Paris can be inferred, whose amplitude depends on the time of the day and on

Corrosion-Fatigue Crack Growth in Plates: A Model Based on the Paris Law

2017-01-01

In this paper, a Paris law-based model is presented whereby crack propagation occurs under cyclic loading in air (fatigue) and in an aggressive environment (corrosion-fatigue) for the case of corner cracks (with a wide range of aspect ratios in the matter of the initial cracks) in finite-thickness plates of 316L austenitic stainless steel subjected to tension, bending, or combined (tension + bending) loading. Results show that the cracks tend during their growth towards a preferential propagation path, exhibiting aspect ratios slightly lower than unity only for the case of very shallow cracks, and diminishing as the crack grows (increasing the relative crack depth)—more intensely in the case of bending than in the case of tension (the mixed loading tension/bending representing an intermediate case). In addition, the crack aspect ratios during fatigue propagation evolution are lower in fatigue (in air) than in corrosion-fatigue (in aggressive environment). PMID:28772798

A Pseudomonas fluorescens isolate (PF-1) resistant to carbapenems was recovered during an environmental survey performed with water from the Seine River (Paris). It expressed a novel Ambler class A carbapenemase, BIC-1, sharing 68 and 59% amino acid identities with beta-lactamases SFC-1 from Serratia fonticola and the plasmid-encoded KPC-2, respectively. beta-Lactamase BIC-1 hydrolyzed penicillins, carbapenems, and cephalosporins except ceftazidime and monobactams. The bla(BIC-1) gene was chromosomally located and was also identified in two other P. fluorescens strains isolated from the Seine River 3 months later.

This paper presents the first, to our knowledge, lidar measurement of an industrial fire plume, which covered the north of the Paris area on 17th April 2015. The fire started in a textile warehouse and rapidly spread by emitting large quantities of aerosols into the low troposphere. A ground based N2-Raman lidar performed continuous measurements during this event. Vertical profiles of the aerosol extinction coefficient, depolarization and lidar ratio are derived. A Monte Carlo algorithm was used to assess the uncertainties on the optical parameters, and to evaluate lidar inversion methods.

An important component of the Paris Agreement is the assessment of comparability across nationally determined contributions (NDCs). Indeed, game-theory literature on international environmental agreements highlights the need for comparable emission-mitigation efforts by countries to avoid free-riding1. At the same time, there are well-recognized links between mitigation and other national priorities, including but not limited to the 17 United Nations Sustainable Development Goals (SDGs)2-6, which raises the question of how such links might influence comparability assessments. Here, using a global integrated assessment model7, we demonstrate that geographical distributions of the influence of meeting the domestic mitigation component of the NDCs on a subset of the broader SDGs may not align with distributions of effort across NDCs obtained from conventional emissions-based or cost-based comparability metrics8-11. This implies that comparability assessments would be altered if interactions between mitigation and other SDGs were accounted for. Furthermore, we demonstrate that the extent to which these distributions differ depends on the degree to which mitigation activities directly affect broader SDGs domestically and indirectly affect international goals, and whether these effects are synergistic or antagonistic. Our analysis provides a foundation for assessing how comparability across NDCs could be better understood in the larger context of sustainability.

Towards Verifying National CO2 Emissions

With the Paris Agreement, nations around the world have pledged their voluntary reductions in future CO2 emissions. Satellite observations of atmospheric CO2 have the potential to verify self-reported emission statistics around the globe. We present a carbon-weather data assimilation system, wherein raw weather observations together with satellite observations of the mixing ratio of column CO2 from the Orbiting Carbon Observatory-2 are assimilated every 6 hours into the NCAR carbon-climate model CAM5 coupled to the Ensemble Kalman Filter of DART. In an OSSE, we reduced the fossil fuel emissions from a country, and estimated the emissions innovations demanded by the atmospheric CO2 observations. The uncertainties in the innovation are analyzed with respect to the uncertainties in the meteorology to determine the significance of the result. The work follows from "On the use of incomplete historical data to infer the present state of the atmosphere" (Charney et al. 1969), which maps the path for continuous data assimilation for weather forecasting and the five decades of progress since.

The objectives of this experiment were to measure intestinal digestibility of AA in rumen undegradable protein (RUP-AA) in soybean meal (SBM) and expeller SBM (SoyPlus, West Central, Ralston, IA; SP) and to determine if these feeds contain a constant protein fraction that is undegradable in the rumen and indigestible in the small intestine, as assumed in the French Institut National de la Recherche Agronomique (Paris, France) and Scandinavian AAT-PBV (AAT = AA absorbed from small intestine; PBV = protein balance in the rumen) models. Three samples of SBM and 3 samples of SP were obtained from the Feed Analysis Consortium Inc. (Savoy, IL). To obtain the RUP fraction, samples were ruminally incubated in situ for 16 h in 4 lactating cows, and the collected rumen undegraded residues (RUR) were pooled by sample. Subsamples of the intact feeds and RUR were crop intubated to 4 cecectomized roosters, and total excreta were collected for 48 h. Intact feeds, RUR, and excreta were analyzed for AA. Basal endogenous AA loss estimates were obtained from fasted birds and were used to calculate standardized digestibility of AA in the intact feeds and RUP-AA. Indigestibility coefficients of the intact feeds were calculated as (100 - % standardized AA digestibility), and indigestibility of the RUR was calculated as [(100 - % ruminal degradation of AA) x [(100 - % standardized RUP-AA digestibility)]/100]. Results indicated that standardized digestibility of feed-AA was similar to standardized digestibility of RUP-AA for SBM and SP samples and that standardized digestibility of individual AA differed within samples. Standardized feed-AA and RUP-AA digestibility values were lowest for Lys and Cys and highest for Trp and Met. Results also indicated that SBM and SP did not contain a constant protein fraction that was both undegradable in the rumen and indigestible in the small intestine. Indigestibility values of RUR were lower than in intact feeds, suggesting that SBM and SP contain a

Urban metabolism and river systems: an historical perspective - Paris and the Seine, 1790-1970

The aim of this paper is to analyse metabolic interaction between Paris and the Seine during the industrial era, 1790-1970, a period marked by strong population growth, technological changes, and the absence of specific legislation on environmental issues. The viewpoint focuses on exchanges of waters and wastes between city and river, quantifying them and tracing their evolution in the light of the strategies implemented by the stakeholders in charge. The study combines industrial ecology, local history and the history of technology. From 1790 to 1850, waste matters, and especially excreta, were considered as raw materials, not refuse: they generated real profits. The removal of human excreta aimed not only at improving urban hygiene, but at producing the fertilizers needed in rural areas. Discharging them into the river was out of the question. But after the 1860s, several factors upset this exploitation, notably domestic water supply: night soil became more and more liquid, difficult to handle and to turn into fertilizer; once utilised, the water had to be removed from the house; at the same time, the sewerage system developed and had negative impacts on the river. Even so, Parisian engineers continued to process sewage using techniques that would not only ensure hygiene but also conciliate economic and agricultural interests: combined sewerage system and sewage farms. Both of these early periods are thus noteworthy for a relative limitation of the river's deterioration by urban wastes. Not until the 1920s, when domestic water supply had become the standard and excreta came to be considered as worthless waste, was the principle of valorisation abandoned. This led to important and long-lasting pollution of the Seine (despite the construction of a treatment plant), aggravating the industrial pollution that had been in evidence since the 1840s. Analysing the priorities that led to the adoption of one principle or another in matters of urban hygiene and techniques

The influence of air-conditioning on street temperatures in the city of Paris

A consequence of urban heat islands in summer is the increased use of air-conditioning during extreme heat events : the use of air-conditioning systems, while cooling the inside of buildings releases waste heat (as latent and sensible heat) in the lower part of the urban atmosphere, hence potentially increasing air street temperatures where the heat is released. This may lead locally to a further increase in air street temperatures, therefore increasing the air cooling demand, while at the same time lowering the efficiency of air-conditioning units. A coupled model consisting of a meso-scale meteorological model (MESO-NH) and an urban energy balance model (TEB) has been implemented with an air-conditioning module and used in combination to real spatialised datasets to understand and quantify potential increases in temperature due to air-conditioning heat releases for the city of Paris . In a first instance, the current types of air-conditioning systems co-existing in the city were simulated (underground chilled water network, wet cooling towers and individual air-conditioning units) to study the effects of latent and sensible heat releases on street temperatures. In a third instance, 2 scenarios were tested to characterise the impacts of likely future trends in air-conditioning equipment in the city : a first scenario for which current heat releases were converted to sensible heat, and a second based on 2030s projections of air-conditioning equipment at the scale of the city. All the scenarios showed an increase in street temperature which, as expected, was greater at night time than day time. For the first two scenarios, this increase in street temperatures was localised at or near the sources of air-conditioner heat releases, while the 2030s air-conditioning scenario impacted wider zones in the city. The amplitude of the increase in temperature varied from 0,25°C to 1°C for the air-conditioning current state, between 0,25°C and 2°C for the sensible heat

Nitrogen food-print: N use and N cascade from livestock systems in relation to pork, beef and milk supply to Paris

A bottom-up approach is constructed to determine N losses from livestock farming systems and to relate these losses to the supply of fresh milk, pig and beef to Paris. First, the three products are expressed in terms of their nitrogen content; then, their fodder equivalent is determined by modelling feed formulas for swine, beef and dairy cows to meet their energy and protein requirements. Fodder deficits in livestock farms are determined by comparing the nutrient requirements of the livestock with the fodder production on the livestock farms. This allowed determining the geography of the livestock systems according to the imports of fodder to the livestock farms from external crop farms. Then we assessed the "farm-gate" N budgets in all crop and livestock farms of the entire livestock systems using data on total N fertilization, atmospheric deposition and manure management practices to finally derive N losses in relation to fodder cultivation and to manure management. Measured in N, the supply of milk, beef and pig to Paris sum 1.85 kg N/cap and the corresponding N losses from the farming systems total 8.9 kg N/cap. N losses per unit of product differ among the three livestock systems according to where and how the fodder is grown and to what densities the livestock is reared.

Simulation of trace metals and PAH atmospheric pollution over Greater Paris: Concentrations and deposition on urban surfaces

Urban areas can be subject not only to poor air quality, but also to contamination of other environmental media by air pollutants. Here, we address the potential transfer of selected air pollutants (two metals and three PAH) to urban surfaces. To that end, we simulate meteorology and air pollution from Europe to a Paris suburban neighborhood, using a four-level one-way nesting approach. The meteorological and air quality simulations use urban canopy sub-models in order to better represent the effect of the urban morphology on the air flow, atmospheric dispersion, and deposition of air pollutants to urban surfaces. This modeling approach allows us to distinguish air pollutant deposition among various urban surfaces (roofs, roads, and walls). Meteorological model performance is satisfactory, showing improved results compared to earlier simulations, although precipitation amounts are underestimated. Concentration simulation results are also satisfactory for both metals, with a fractional bias <0.5. Concentrations of benzo[a]pyrene are overestimated, probably because continental emissions may be overestimated. Concentrations of benzo[b]fluoranthene and indeno[1,2,3,cd]pyrene are underestimated, in part because of null boundary conditions. PAH deposition fluxes are consistent with earlier measurements obtained in the Greater Paris region. The model simulation results suggest that both wet and dry deposition processes need to be considered when estimating the transfer of air pollutants to other environmental media. Dry deposition fluxes to various urban surfaces are mostly uniform for PAH, which are entirely present in fine particles. However, there is significantly less wall deposition compared to deposition to roofs and roads for trace metals, due to their coarse fraction. Meteorology, particle size distribution, and urban morphology are all important factors affecting air pollutant deposition. Future work should focus on the collection of data suitable to evaluate the

Paris polyphylla, a traditional antipyretic-detoxicate chinese medicinal herb, has been applied extensively in cancer treatments for nearly 2000 years. The purpose of the present study is to evaluate the potential anti-osteosarcoma effects of Paris polyphylla ethanol extract (PPEE) and to investigate its underlying mechanisms. The antiproliferation activity of PPEE was tested on 143B, MG-63, U-2 OS and hFOB1.19 cells using MTT assay. The pro-apoptotic and cell cycle arrest effects of PPEE were confirmed by Hoechst 33342 staining and flow cytometry. The antimigratory, anti-invasive and antivasculogenic mimicry (VM) effects of PPEE were investigated by wound healing, Transwell and 3D culture assays. Mouse xenograft model was used to examine its anti-osteosarcoma efficacy in vivo. Hematologic profiles and hepatorenal functions were evaluated to assess the toxicity of PPEE. PPEE evidently suppressed cell proliferation of 143B, MG-63 and U-2 OS with IC50 values of 10-60[Formula: see text][Formula: see text]g/mL, but showed little cytotoxicity against normal osteoblastic cell. PPEE promoted apoptosis in 143B cell via caspase activation, increased Bax/Bcl-2 ratio and PARP cleavage. It also induced G2/M phase arrest associated with elevated phosphorylation of CDK1, Cdc25C, Chk2 and down-regulation of cyclin B1, CDK1, Cdc25C expression. Additionally, PPEE inhibited 143B cell migration, invasion and VM formation at noncytotoxic concentrations through decreasing the expression of FAK, Mig-7, MMP2 and MMP9. Finally, daily oral administration of PPEE for four weeks exhibits potent antitumor and anti-VM activity in 143B xenograft model with low toxicity. Taken together, these findings demonstrated PPEE possesses anti-osteosarcoma and anti-VM activity in vitro and in vivo, and therefore is a potential candidate for osteosarcoma treatment.

We provide a quantitative description of the French national herbarium vascular plants collection dataset. Held at the Muséum national d’histoire naturelle, Paris, it currently comprises records for 5,400,000 specimens, representing 90% of the estimated total of specimens. Ninety nine percent of the specimen entries are linked to one or more images and 16% have field-collecting information available. This major botanical collection represents the results of over three centuries of exploration and study. The sources of the collection are global, with a strong representation for France, including overseas territories, and former French colonies. The compilation of this dataset was made possible through numerous national and international projects, the most important of which was linked to the renovation of the herbarium building. The vascular plant collection is actively expanding today, hence the continuous growth exhibited by the dataset, which can be fully accessed through the GBIF portal or the MNHN database portal (available at: https://science.mnhn.fr/institution/mnhn/collection/p/item/search/form). This dataset is a major source of data for systematics, global plants macroecological studies or conservation assessments. PMID:28195585

One of the priorities of the "Plan against the Cancer" in France is to ensure the discussion of all cancer cases in a multidisciplinary meeting staff (RCP). The multidisciplinary collaboration is proposed to guarantee a discussion between specialists in every cases, particularly in complex cases. The aim of this study was to compare the therapeutic decision taken in four RCP in Paris Île-de-France academic centres for three identical cases. Three cases of urological oncology (prostate cancer [PCa], renal cell carcinoma [RCC] and bladder tumour) were selected by a single urologist, not involved in further discussion. These cases were blindly presented in four academic urology department from Paris: Pitié-Salpêtrière Hospital, Mondor Hospital, the Georges-Pompidou European Hospital and Foch Hospital. The four centres met the criteria of quality of RCP in terms of multidisciplinarity, frequency and standardization. The therapeutic suggestions were similar in the RCC cases, there were differences in the surgical approaches and preoperative work-up in the PCa case and, lastly, the proposals were different for the bladder cancer case. The decisions relies on clinical data and preoperative work-up but also on the experience and habits of the centre of excellence. For complex cases that does not fit with current guidelines, the panel discussion can lead to different therapeutic options from a centre to another and is largely influenced by the local organisation of the RCP.

The count rates achieved in neutron powder diffraction experiments create difficulties for high-pressure experiments because large sample volumes (˜100 mm3) must be used. Until recently it has been difficult to build suitable pressure cells with such large volumes and hence the maximum pressure for neutron diffraction has remained at the relatively low value of 3 GPa. We have now developed a pressure cell (the Paris-Edinburgh cell) which is capable of exceeding 10 GPa with a sample volume of ˜100 mm3 for use at the U.K. spallation source ISIS. Considerable effort has been devoted to the opimization of the cell, shielding, and detector geometry to enable the best possible data to be recorded. Finite-element calculations to correct for the systematic errors introduced by the attenuation of the pressure-cell materials have been developed and tested. As a result of this work we are now able to obtain accurate structural data to ˜12 GPa and recent studies of phase IV of ND3, the behaviour of the O-D bondlength in D2O ice VIII, and the structural pressure dependence of B4C illustrate the importance of the extension of neutron-diffraction studies to such pressures.

It is essential for children suffering from or at risk of lead poisoning to have regular follow-up, and specifically for their blood lead (Pb) levels to be monitored. The present study assessed the occurrence of late follow-up testing of blood lead levels in children in Greater Paris, and factors related to such delays. Since 1992, the SSSIILF has been systematically recording data on lead levels in blood tests conducted for screening and follow-up in Greater Paris. For Pb greater or equal to 45 microg/dL (Group 4), a further blood lead test has to be done within three weeks. For levels of 25 microg/dL < or = Pb < 45 microg/dL (Group 3) and 10 microg/dL < or = Pb < 25 microg/dL (Group 2), a second test must be done within 6 months. For Pb less than 10 microg/dL combined with one or more risk factors (Group 1: children at risk of poisoning), a second test is required within 6 to 12 months. Children aged 1 to 6 years who were screened between 1992 and 2002 were selected. The occurrence of late follow-up testing was estimated, and the independent effect of each variable associated with a delay was measured using a logistic regression model. Delays in re-testing were reported for 66.9% of Group 4 children (n=356), 45.3% of Group 3 children (n=921), 74.1% of Group 2 children (n=5,466), and 88.7% of Group 1 children (n=15,612). In the three groups with Pb greater or equal to 10 microg/dL, there was better follow-up (i.e. less delay to re-testing) for children screened most recently, those whose initial blood lead test results were elevated, those who lived in sub-standard housing built before 1949, and those who lived in suburban districts of Paris. The delay was longer for children aged 4 to 6 compared to younger children. When the size of the group was large enough, these differences were significant. In Group 1, similar results were observed except for a home address in a suburban district. Furthermore, follow-up was better for children of Sub-Saharan African parents

Sainte-Anne Hospital is the largest psychiatric hospital in Paris. Its long and fascinating history began in the 18th century. In 1952, it was at Sainte-Anne Hospital that Jean Delay and Pierre Deniker used the first neuroleptic, chlorpromazine, to cure psychiatric patients, putting an end to the expansion of psychosurgery. The Department of Neuro-psychosurgery was created in 1941. The works of successive heads of the Neurosurgery Department at Sainte-Anne Hospital summarized the history of psychosurgery in France. Pierre Puech defined psychosurgery as the necessary cooperation between neurosurgeons and psychiatrists to treat the conditions causing psychiatric symptoms, from brain tumors to mental health disorders. He reported the results of his series of 369 cases and underlined the necessity for proper follow-up and postoperative re-education, illustrating the relative caution of French neurosurgeons concerning psychosurgery. Marcel David and his assistants tried to follow their patients closely postoperatively; this resulted in numerous publications with significant follow-up and conclusions. As early as 1955, David reported intellectual degradation 2 years after prefrontal leucotomies. Jean Talairach, a psychiatrist who eventually trained as a neurosurgeon, was the first to describe anterior capsulotomy in 1949. He operated in several hospitals outside of Paris, including the Sarthe Psychiatric Hospital and the Public Institution of Mental Health in the Lille region. He developed stereotactic surgery, notably stereo-electroencephalography, for epilepsy surgery but also to treat psychiatric patients using stereotactic lesioning with radiofrequency ablation or radioactive seeds of yttrium-90. The evolution of functional neurosurgery has been marked by the development of deep brain stimulation, in particular for obsessive-compulsive disorder, replacing the former lesional stereotactic procedures. The history of Sainte-Anne Hospital's Neurosurgery Department sheds

The paper is aimed at studying the diversity of endophytic fungi community from Paris polyphylla var. yunnanensis, and to provide a scientific basis for the utilization value of the endophytic fungi as bioactive material resources. In the present study, endophytic fungi were isolated from roots, rhizomes and leaves of wild P. polyphylla var. yunnanensis collected from Baoshan, Heqing county and Songming city of Yunnan province, and identified and classified by morphological methods together with its ITS sequence analysis. Seven and forty-nine strains of endophytic fungi were isolated from P. polyphylla var. yunnanensis. They were identified belonging to 41 genus. In these 41 genus, 3 genus exist in root only, 12 genus only exist in rhizome and 8 genus only exist in leaf. There was difference in endophytic fungi isolated from different sample sites. Endophytic fungi diversity from rhizomes of Heqing site was the highest. Endophytic fungi similarity coefficient was low among different sites and tissues. Based on these results, it is reasonable to propose that endophytic fungi of P. polyphylla var. yannanensis from different tissue and different sample sites has a certain difference which is possibly relate to their different habitats, different structure and composition of each tissue.

Characterizing the seasonal cycle and vertical structure of ozone in Paris, France using four years of ground based LIDAR measurements in the lowermost troposphere

Systematic ozone LIDAR measurements were completed during a 4 year period (2011-2014) in Paris, France to study the seasonal variability of the vertical structure of ozone in the urban boundary layer. In addition, we use in-situ measurements from the surface air quality network that is located in Paris (AIRPARIF). Specifically, we use ozone and NO2 measurements made at two urban stations: Paris13 (60 m ASL) and the Eiffel Tower (310 m ASL) to validate and interpret the LIDAR profiles. Remote sensed tropospheric NO2 integrated columns from the SAOZ instrument located in Paris are also used to interpret ozone measurements. Comparison between ozone LIDAR measurements averaged from 250 m to 500 m and the Eiffel Tower in-situ measurements shows that the accuracy of the LIDAR (originally ±14 μg·m-3) is significantly improved (±7 μg·m-3) when a small telescope with a wide angular aperture is used. Results for the seasonal cycle of the ozone vertical gradient are found to be similar using two methods: (1) measured differences between AIRPARIF stations with measurements at 60 m ASL and 310 m ASL and (2) using LIDAR profiles from 300 m to the top of the Planetary Boundary Layer (PBL). Ozone concentrations measured by the LIDAR increase with altitude within the PBL, with a steeper gradient in winter (60 μg·m-3·km-1) and a less strong gradient in summer (20 μg·m-3·km-1). Results show that in winter, there is a sharp positive gradient of ozone at the surface, which is explained by ozone titration by NO combined with increased atmospheric stability in winter. In the afternoon during summer, photochemistry and vertical mixing are large enough to compensate for ozone titration near the surface, where NOx is emitted, and there is no gradient in ozone observed. In contrast, in the summer during the morning, ozone has a sharper positive vertical gradient similar to the winter values. Comparison of the vertically averaged ozone concentrations up to (0-3 km) and urban layer

A hydrodynamic model which takes into account the aquitard storage effect was developed for the deep multilayered system including the Dogger aquifer and its surroundings in the Paris Basin. It provides a good explanation for a series of observations in the Dogger concerning, for instance, the hydraulic head, the salinity and the transmissivity. The calibration of the model also makes it possible to estimate some unmeasured parameters such as the aquifer and aquitard storage coefficients. Finally, the results of simulations of the transport of 4He and 14C strengthen the representativeness of the model. The Darcy average horizontal velocity in the Dogger, obtained with the model, is of the order of 0.33m year -1.

Although the co-benefits from addressing problems related to both climate change and air pollution have been recognised, there is not much evidence comparing the mitigation costs and economic benefits of air pollution reduction for alternative approaches to meeting greenhouse gas targets. We analysed the extent to which health co-benefits would compensate the mitigation cost of achieving the targets of the Paris climate agreement (2°C and 1·5°C) under different scenarios in which the emissions abatement effort is shared between countries in accordance with three established equity criteria. Our study had three stages. First, we used an integrated assessment model, the Global Change Assessment Model (GCAM), to investigate the emission (greenhouse gases and air pollutants) pathways and abatement costs of a set of scenarios with varying temperature objectives (nationally determined contributions, 2°C, or 1·5°C) and approaches to the distribution of climate change methods (capability, constant emission ratios, and equal per capita). The resulting emissions pathways were transferred to an air quality model (TM5-FASST) to estimate the concentrations of particulate matter and ozone in the atmosphere and the resulting associated premature deaths and morbidity. We then applied a monetary value to these health impacts by use of a term called the value of statistical life and compared these values with those of the mitigation costs calculated from GCAM, both globally and regionally. Our analysis looked forward to 2050 in accordance with the socioeconomic narrative Shared Socioeconomic Pathways 2. The health co-benefits substantially outweighed the policy cost of achieving the target for all of the scenarios that we analysed. In some of the mitigation strategies, the median co-benefits were double the median costs at a global level. The ratio of health co-benefit to mitigation cost ranged from 1·4 to 2·45, depending on the scenario. At the regional level, the costs of

On November 13th, 2015, terrorist bomb explosions and gunshots occurred in Paris, France, with 129 people immediately killed, and more than 300 being injured. This article describes the staff organization, surgical management, and patterns of injuries in casualties who were referred to the Teaching European Hospital Georges Pompidou. This study is a retrospective analysis of the pre-hospital response and the in-hospital response in our referral trauma center. Data for patient flow, resource use, patterns of injuries and outcomes were obtained by the review of electronic hospital records. Forty-one patients were referred to our center, and 22 requiring surgery were hospitalized for>24h. From November 14th at 0:41 A.M. to November 15th at 1:10 A.M., 23 surgical interventions were performed on 22 casualties. Gunshot injuries and/or shrapnel wounds were found in 45%, fractures in 45%, head trauma in 4.5%, and abdominal injuries in 14%. Soft-tissue and musculoskeletal injuries predominated in 77% of cases, peripheral nerve injury was identified in 30%. The mortality rate was 0% at last follow up. Rapid staff and logistical response, immediate access to operating rooms, and multidisciplinary surgical care delivery led to excellent short-term outcomes, with no in-hospital death and only one patient being still hospitalized 45days after the initial event.

During this one-year project, two thirds of the days exceeding the PM2.5 2015 EU annual limit value of 25 μg m-3 were due to continental import from countries located northeast, east of France. This result questions the efficiency of local, regional and even national abatement strategies during pollution episodes, pointing to the need for a wider collaborative work with the neighbouring countries on these topics. Nevertheless, emissions of local anthropogenic sources lead to higher levels at the URB and SUB sites compared to the others (e.g. 26% higher on average at the URB than at the NWR site for PM2.5, during the whole campaign), which can even be emphasised by specific meteorological conditions such as low boundary layer heights. OM and secondary inorganic species (nitrate, non-sea-salt sulfate and ammonium, noted SIA) are mainly imported by mid- or long-range transport (e.g. for NWR plotted against URB sites: slope = 0.79, r2=0.72, n=335 for OM, and slope = 0.91, r2=0.89, n=335 for SIA) whereas EC is primarily locally emitted (e.g. for SOR plotted against URB sites: slope = 0.27; r2=0.03; n=335). This database will serve as a basis for investigating carbonaceous aerosols, metals as well as the main sources and geographical origins of PM in the region of Paris.

In The Mystery of Capitalism , the darling of neoliberalism, Hernando de Soto posits that secure property titles explain “why capitalism triumphs in the West and fails everywhere else.” While social scientists have taken him to task for an oversimplification of the causes and remedies of poverty, historians have contributed little to this important policy debate. Applying comparative methods across time and space, such a retrospective analysis exposes serious flaws in de Soto’s thesis. Case studies of Paris, Chicago, and Mexico City covering successive, fifty-year periods support his contention that property law was the single most important factor in determining the fate of rural migrants trying to find a place to live in these exploding cities. But in each case, residential property played a far more complex role in creating the social and physical geography of the city than its simple exchange value. This article illuminates some of these alternative economic uses and embedded cultural meanings of identities of place. It also shows how urban growth machines create capital value in property for some by creating environmental injustice of substandard conditions of everyday life for others.

Because of organ shortage and a constant imbalance between available organs and candidates for liver transplantation, expanded criteria donors are needed. Experience shows that there are wide variations in the definitions, selection criteria, and use of expanded criteria donors according to different geographic areas and different centers. Overall, selection criteria for donors have tended to be relaxed in recent years. Consensus recommendations are needed. This article reports the conclusions of a consensus meeting held in Paris in March 2007 with the contribution of experts from Europe, the United States, and Asia. Definitions of expanded criteria donors with respect to donor variables (including age, liver function tests, steatosis, infections, malignancies, and heart-beating versus non-heart-beating, among others) are proposed. It is emphasized that donor quality represents a continuum of risk rather than "good or bad." A distinction is made between donor factors that generate increased risk of graft failure and factors independent of graft function, such as transmissible infectious disease or donor-derived malignancy, that may preclude a good outcome. Updated data concerning the risks associated with different donor variables in different recipient populations are given. Recommendations on how to safely expand donor selection criteria are proposed.

Active hospital-based surveillance program of incident episodes of candidemia due to common species in 24 tertiary care hospitals in the Paris area, France between October 2002 and September 2010. Among 2,507 adult cases included, 2,571 Candida isolates were collected and species were C. albicans (56 %), C. glabrata (18.6 %), C. parapsilosis (11.5 %), C. tropicalis (9.3 %), C. krusei (2.9 %), and C. kefyr (1.8 %). Candidemia occurred in ICU in 1,206 patients (48.1 %). When comparing ICU vs. non-ICU patients, the former had significantly more frequent surgery during the past 30 days, were more often preexposed to fluconazole and treated with echinocandin, and were less frequently infected with C. parapsilosis. Risk factors and age remained unchanged during the study period. A significant increased incidence in the overall population and ICU was found. The odds of being infected with a given species in ICU was influenced by risk factors and preexposure to fluconazole and caspofungin. Echinocandins initial therapy increased over time in ICU (4.6 % first year of study, to 48.5 % last year of study, p < 0.0001). ICU patients had a higher day-30 death rate than non-ICU patients (odds ratio [OR] 2.12; 95 % confidence interval [CI] 1.66-2.72; p < 0.0001). The day-30 and early (

Hazards of decreasing marine oxygen: the near-term and millennial-scale benefits of meeting the Paris climate targets

NASA Astrophysics Data System (ADS)

Battaglia, Gianna; Joos, Fortunat

2018-06-01

Ocean deoxygenation is recognized as key ecosystem stressor of the future ocean and associated climate-related ocean risks are relevant for current policy decisions. In particular, benefits of reaching the ambitious 1.5 °C warming target mentioned by the Paris Agreement compared to higher temperature targets are of high interest. Here, we model oceanic oxygen, warming and their compound hazard in terms of metabolic conditions on multi-millennial timescales for a range of equilibrium temperature targets. Scenarios where radiative forcing is stabilized by 2300 are used in ensemble simulations with the Bern3D Earth System Model of Intermediate Complexity. Transiently, the global mean ocean oxygen concentration decreases by a few percent under low forcing and by 40 % under high forcing. Deoxygenation peaks about a thousand years after stabilization of radiative forcing and new steady-state conditions are established after AD 8000 in our model. Hypoxic waters expand over the next millennium and recovery is slow and remains incomplete under high forcing. Largest transient decreases in oxygen are projected for the deep sea. Distinct and near-linear relationships between the equilibrium temperature response and marine O2 loss emerge. These point to the effectiveness of the Paris climate target in reducing marine hazards and risks. Mitigation measures are projected to reduce peak decreases in oceanic oxygen inventory by 4.4 % °C-1 of avoided equilibrium warming. In the upper ocean, the decline of a metabolic index, quantified by the ratio of O2 supply to an organism's O2 demand, is reduced by 6.2 % °C-1 of avoided equilibrium warming. Definitions of peak hypoxia demonstrate strong sensitivity to additional warming. Volumes of water with less than 50 mmol O2 m-3, for instance, increase between 36 % and 76 % °C-1 of equilibrium temperature response. Our results show that millennial-scale responses should be considered in assessments of ocean deoxygenation and associated

The National Museum of Natural History played a crucial role in the formation of Polish scientific elites in the 19th century. Many Polish students were attending in Paris natural history, botany, zoology, chemistry and mineralogy courses. The Warsaw Society of Friends of Learning was the largest scientific society and one of the most important scientific institutions in Poland. It had also an impact on the political and cultural life of the country, occupied and deprived of freedom at that time. Amongst its founders and members, could be found listeners to the lectures of Lamarck, Haüy, Vauquelin, Desfontaines, Jussieu. Moreover, seven professors of the National Museum of Natural History were elected foreign members of the Warsaw Society of Friends of Learning: Cuvier, Desfontaines, Haüy, Jussieu, Latreille, Mirbel, Vauquelin. The article analyses this choice and underlines the relationship between these scientists and Warsaw's scientists. The results of this research allow to confirm that the National Museum of Natural History was the most important foreign institution in the 19th century for Polish science, and more specifically natural sciences.

New characterization aspects of carbonate accumulation horizons in Chalky Champagne (NE of the Paris Basin, France)

The soil profiles of the Champagne area (NE of Paris Basin, France) occasionally show carbonate accumulation horizons (CAHs). From the top to the bottom, these soil profiles include a rendic leptosol horizon, a Quaternary cryoturbated paleosol (QCP), and a chalky substratum. The CAHs are located in the top part of the QCP. This study is aimed at highlighting the specific characteristics of CAHs compared to other soil profile horizons using geophysics, geochemistry, micromorphology, and mercury injection porosimetry. It is the first essential step for understanding the impact of CAHs on water transfers into the Champagne soil profiles. Our analyses show that Champagne CAHs are not systematically characterized by a typical induration unlike generally put forward in the regional literature. They are more porous and heterogeneous than their parent material (QCP). Carbonate accumulation horizons are also characterized by singular colorimetric parameters that are linked to their geochemical specific content, even if they bear a signature of the initial QCP before the pedogenic modification.

Forty-three percent of the tuberculosis cases reported in France are from the Ile de France region. The incidence of tuberculosis in this region is 33 cases per 100,000 inhabitants, twice the national average. A restriction fragment length polymorphism (RFLP) analysis was performed with clinical isolates of Mycobacterium tuberculosis isolated during 1995 in 10 hospitals in Paris and surrounding areas to detect tuberculosis transmission and define the factors associated with clustering in this population. The molecular markers used were the insertion sequence IS6110 and the direct repeat (DR) sequence. Social, demographic, and clinical data were collected from the patients’ medical files. Ten patients with isolates with a single copy of IS6110 were excluded from further analysis. Twenty-four patients with false-positive cultures due to laboratory contamination (based on RFLP analysis with IS6110 and examination of patient data) were also excluded. The study was then conducted with 272 strains isolated from 272 patients. Further fingerprinting was performed by using the DR element with strains with patterns by RFLP analysis with IS6110 that differed by one band only and strains with identical patterns by RFLP analysis with IS6110 and with low numbers of copies of IS6110. The combined use of both markers identified unique patterns for 177 strains and clustered 95 (35.7%) strains in 26 groups, each containing isolates from 2 to 12 patients. The clustering was strongly associated with homelessness and the male sex. It was not associated with age, birth in a foreign country, human immunodeficiency virus positivity, or residence in hostels or prison. Isolates from homeless people were often included in large clusters, and homeless people could be the source of tuberculosis transmission for more than 50% of the clustered patients. These results suggest that homeless people play a key role in the spread of M. tuberculosis in the community and that poor socioeconomic

Building online teaching materials is a highly time and energy consuming task for teachers of a single university. With the help of the Collège des pathologistes, we initiated a French national university network for building mutualized online teaching pathology cases, tests and other pedagogic resources. Nineteen French universities are associated to this project, initially funded by UNF3S (http://www.unf3s.org/). One national e-learning Moodle platform (http://virtual-slides.univ-paris7.fr/moodle/) contains texts, medias and URL pointing toward decentralized virtual slides. The Moodle interface has been explained to the teachers since september 2011 using web-based conferences with screen-sharing. The following contents have been created: 20 clinical cases, several tests with multiple choices and short answer questions, and gross examination videos. A survey with 16 teachers and students showed a 94 % satisfaction rate, most of the 16 participants being favorable to the development of e-learning, in parallel with other courses in classroom. These tools will be further developed for the different study levels of pathology. In conclusion, these tools offer very interesting perspectives for pathology teaching. The organization of a national inter-university network is a useful way to create and share numerous and good-quality pedagogic resources. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

Studies on contraceptive use by patients with substance use disorders (SUD) show a concerning low use of contraception. Mainly conducted in USA, they could be irrelevant to patients attending European SUD treatment centers, especially since these studies mostly investigate women suffering from social exclusion, severe material deprivation andopiates use with frequent high-risk drug use and sexual behaviors including sex trade, frequently not currently attending treatment centers. The purpose of this study is to describe contraceptive use by patients, both male and female, since contraception can not only be considered as a female problem, with severe SUD in two free clinics in Paris, France. An anonymous self-report questionnaire was distributed to literate patients followed in two generalist substance use disorders treatment centers in hospitals of Paris, France: Espace Murger and Centre Cassini, during 5 weeks between February and March 2016. Out of the 78 respondents (with an age mean 40.7 years, in which women are represented as 48.1%, and 29.7% of them have children), 53 have had at least one sexual partner in the last 6 months. Contraception was "always" used by 55.3% of sexually active patients, "sometimes" by 19.1%, and "not" used by 25.5%. Male condoms were the main contraceptive method. The use of intrauterine devices was low, contrarily to what is observed in the French general population. However, the knowledge of contraceptive methods was common. In this population, with a high prevalence of at risk sexual behavior, the use of contraceptive methods is lower than in French general population. During standard care for SUD, contraception and desire to be a parent should be discussed and patients empowered to make their own choices. Lack of knowledge does not seem to be a hindrance to the use of contraception, but other sociological, psychological, or medical factors may limit contraceptive access and long-term use, especially for the long

Endophyte microorganisms live inside plants without causing them any apparent damage. Recently, endophytic microorganisms have attracted attention because they can produce bioactive compounds of biotechnological interest. The endophytic microorganisms in Paris polyphylla var. yunnanensis (Liliaceae) - a species used since antiquity in traditional Chinese medicine - are under scrutiny because they may be responsible for producing the bioactive metabolites associated with the plant. The levels of bioactive metabolites in the rhizomes of P. polyphylla increase with rhizome age. To elucidate the roles played by endophytes in the accumulation of bioactive metabolites, we investigated the community structure and diversity of the endophytic microorganisms in P. polyphylla rhizomes of different ages (4, 6, and 8 years) using 16S rRNA and internal transcribed spacer (ITS) sequence analysis. 16S rDNA amplicon pyrosequencing revealed that the number of operational taxonomic units was lower in the 8-year-old samples than in the other samples. A total of 28 phyla were observed in the P. polyphylla samples and the predominant bacteria were of the Cyanobacteria and Proteobacteria phyla. Moreover, the percentage of Cyanobacteria increased with rhizome age. Similarly, ITS1 amplicon pyrosequencing identified developmental changes in the most abundant fungal classes; some classes were more prevalent in the 8-year-old rhizomes than in younger rhizomes, indicating the importance in secondary metabolism in older rhizomes. Our study showed that endophyte microorganism diversity and prevalence depend on P. polyphylla rhizome age. There was also an indication that some endophyte microorganisms contribute to the higher saponin content in older P. polyphylla specimens.

Urban compaction vs city sprawl: impact of road traffic on air quality in the greater Paris

Urban pollution remains a major sanitary and economic concern. In France, particulate pollution is known to cause 48,000 premature deaths every year (Santé Publique France, 2016), while the economic cost of air pollution reaches almost 25 billion euros per year (CGDD, 2012). In the Greater Paris, despite strengthened emission standards, restricted traffic areas, car-sharing and incentives for electric vehicle use, road transport plays a substantial role in the exposure of inhabitants to high levels of pollutants. In this context, urban planning could possibly constitute an innovative strategy to reduce emissions from road traffic, through its actions on transport demand, travel distances, modal shift (public transportation, cycling, walking...) or even proximity to emitters. We have developed a multi-scalar modeling of urban pollution by coupling an urban economic growth model NEDUM (CIRED), a model for urban mobility (LISA), a traffic emission model (LISA) and the CHIMERE Chemistry-Transport model (CTM) for air quality simulation (LISA). The innovative aspect of this modeling system is to integrate into a classic CTM the mechanisms underlying the dynamics of an urban system. This way, we establish a quantitative and comprehensive link between a given urban scenario, the associated public and individual transport matrix, and local air quality. We then make it possible to highlight the levers of energy consumption reductions inside compact or sprawled cities. We have been working on the Ile de France region (centered on the Paris agglomeration) which relies on a broad urban structure of megacity, a high density of housing and an expanding urban peripheral zone, clearly raising the issue of transport demand, mobility and traffic congestion. Two scenarios, considering opposite urban development policies from the 1960s to 2010, have been simulated over the whole modelling chain. The first one promotes a dense and compact city while the second favors city spread

This study aims to investigate the association between social contact and social support and women's breast cancer screening (BCS) practices, taking their socioeconomic status (SES) into account. The SIRS survey was conducted in 2010 in the Paris metropolitan area among a representative sample of 3000 French-speaking adults. For the 784 women aged 50years or older with no history of breast cancer, multivariate logistic regressions and bootstrap methods were used to analyze the factors associated with never having undergone BCS. 6.5% of these women had never undergone BCS. In multivariate analysis, being older, having a low education level, having poor-quality health insurance, and having one or less than one social contact per 3-day period were significantly associated with never having undergone BCS during their lifetime, but the level of social support was not. The strength of the association with a low frequency of social contact tended to increase with age. This study analyzed the role of social contact in social inequalities in BCS practices in the Paris metropolitan area. Like SES, social integration and social isolation should be taken into consideration by public health professionals and practitioners when planning BCS programs and incentives. © 2013.

Rhizomes of the perennial herb Paris polyphylla have been used in traditional Chinese medicine for hundreds of years. Agricultural production of the rhizomes requires 7-10 years, which is too long to meet the demand of the medicinal industry. Therefore, studies on improving the yield of the herb and shortening the culturing period are imperative. The present work aimed to investigate the effect of sodium bisulfite (NaHSO (3)) on rhizome yield and quality, as well as some related metabolic features of P. polyphylla. The rhizome yield was improved by NaHSO (3) treatment in long-term experiments conducted during 2006 and 2007, with 2 mM NaHSO (3) giving the highest yield. HPLC analysis revealed that NaHSO (3) treatment increased the total saponin content (49 %), including three pennogenin glycosides and two diosgenin glycosides. In a short-term experiment, NaHSO (3) treatment resulted in an enhanced net photosynthetic rate (Pn) for about 4 days without significant changes in the chlorophyll or carotenoid content. The total soluble sugars and sucrose contents in the leaves also significantly increased after 2 mM NaHSO (3) treatment, whereas the starch content changed only slightly. The activities of the enzymes involved in ammonium assimilation (glutamine synthetase [GS] and glutamate dehydrogenase [GDH]) were not significantly influenced. In a long-term experiment, chlorophylls and carotenoids were not significantly affected, and neither was the starch content in leaves, but the total soluble sugars and sucrose contents in leaves increased significantly. The NaHSO (3) treatment significantly increased GS and GDH activities. These results indicate that NaHSO (3) treatment improved the rhizome yield in P. polyphylla, not only through enhancement of Pn but also by improving carbohydrate accumulation and ammonium assimilation. The increased saponin content after NaHSO (3) treatment was indicative of high rhizome quality. (c) Georg Thieme Verlag KG Stuttgart . New York.

The Human Variome Project (HVP) has established a pilot program with the International Society for Gastrointestinal Hereditary Tumours (InSiGHT) to compile all inherited variation affecting colon cancer susceptibility genes. An HVP-InSiGHT Workshop was held on May 10, 2010, prior to the HVP Integration and Implementation Meeting at UNESCO in Paris, to review the progress of this pilot program. A wide range of topics were covered, including issues relating to genotype-phenotype data submission to the InSiGHT Colon Cancer Gene Variant Databases (chromium.liacs.nl/LOVD2/colon_cancer/home.php). The meeting also canvassed the recent exciting developments in models to evaluate the pathogenicity of unclassified variants using in silico data, tumor pathology information, and functional assays, and made further plans for the future progress and sustainability of the pilot program. © 2011 Wiley-Liss, Inc.

Speleothem-like deposits that develop underground in urban areas are an archive of the environmental impact of anthropic activities that has been little studied so far. In this paper, the sulfate content in shallow groundwater from northern Paris (France) is compared with the sulfur content in two 300-year-old urban carbonate deposits that grew in a historical underground aqueduct. The present-day waters of the aqueduct have very high sulfur and calcium contents, suggesting pollution from gypsum dissolution. However, geological gypsum levels are located below the water table. Sulfur content was measured by micro-X-ray fluorescence in these very S-rich carbonate deposits (0.5 to 1% of S). A twofold S increase during the second half of the 1800s was found in both samples. These dates correspond to two major periods of urbanization above the site. We discus three possible S sources: anthropic sources (industries, fertilizers…), volcanic eruptions and input within the water through gypsum brought for urbanization above the studied site (backfill with quarry waste) since the middle of the 19th century. For the younger second half of the studied section, S input from gypsum brought during urbanization was confirmed by the study of isotopic sulfur composition (δ 34 S=+15.2‰ at the top). For the oldest part, several sulfur peaks could be related to early industrial activity in Paris, that caused high local air pollution, as reported in historical archives but also to historical gypsum extraction. This study provides information on the origin and timing of the very high SO 4 2- levels measured nowadays within the shallow groundwater, thus demonstrating the interest in using carbonate deposits in urban areas as a proxy for the history of urbanization or human activities and their impact on water bodies.

The impact of migration and country or region of origin on sexual behaviours and prevention of the sexual transmission of HIV has been scarcely studied in France. The objective of this study was to evaluate if and how individual attitudes of prevention towards HIV infection are different according to country or region of origins in Paris area, France. 3006 individuals were interviewed in the Paris metropolitan area in 2010. Outcome variables were (i) the intention of the individual to protect oneself against HIV, and (ii) the adoption of a condom-based approach for protection against HIV. To explore factors associated with these outcomes, we constructed multivariate logistic regression models, first taking into account only demographic variables -including country of origin-, then successively adding socioeconomic variables and variables related to sexual behaviour and HIV perception and prevention behaviour. French and foreign people who have origins in Sub-Saharan Africa declared more intentions to protect themselves than French people with French parents (in foreign men, aOR = 3.43 [1.66-7.13]; in foreign women, aOR = 2.94 [1.65-5.23]), but did not declare more recourse to a condom-based approach for protection against HIV (in foreign men, aOR = 1.38 [0.38-4.93]; in foreign women, aOR = 0.93 [0.40-2.18]). Conversely, foreign women and French women from foreign origin, especially from Maghreb (Northern Africa), reported less intention of protection than French women with French parents. These results underline the importance of taking culture and origins of target populations into consideration when designing information, education and communication about HIV and sexually transmitted diseases. These results also draw attention to fractions of the general population that could escape from prevention messages.

The objectives of this experiment were to measure intestinal digestibility of AA in the rumen-undegraded protein fraction (RUP-AA) of distillers dried grains with solubles (DDGS) and fish meal (FM) samples and to determine whether these feeds contain a constant protein fraction that is undegradable in the rumen and indigestible in the small intestine, as assumed in the French Institut National de la Recherche Agronomique (Paris, France) and Scandinavian AAT-PBV (AAT = AA absorbed from small intestine; PBV = protein balance in the rumen) models. Five sources of DDGS and 5 sources of FM were obtained from Feed Analysis Consortium, Inc. (Champaign, IL). To obtain the rumen-undegradable protein fraction, samples were ruminally incubated in situ for 16 h in 4 lactating cows, and the collected rumen-undegraded residues (RUR) were pooled by sample. Subsamples of the intact feeds and RUR were crop-intubated to 4 cecectomized roosters, and total excreta were collected for 48 h. Intact feeds, RUR, and excreta were analyzed for AA. Basal endogenous AA loss estimates were obtained from fasted birds and were used to calculate standardized digestibility of RUP-AA and AA in the intact feeds. Indigestibility coefficients of the intact feeds were calculated as (100 - % standardized AA digestibility), and indigestibility of the RUR was calculated as [(100 - % ruminal degradation of AA) x (100 - % standardized RUP-AA digestibility)/100]. Results indicate that standardized digestibility of feed-AA differs from RUP-AA for DDGS samples but not for FM samples, and that standardized digestibility of individual AA differs within samples. For the DDGS samples, standardized feed-AA and RUP-AA digestibility values were most often lowest for His and Lys and highest for Met and Trp. For FM samples, standardized feed-AA and RUP-AA digestibility values were most often lowest for His and highest for Trp. Results also indicate that DDGS and most FM samples do not contain a constant protein fraction

21st Century Sea-Level Rise in Line with the Paris Accord

As global average sea-level rises in the early part of this century there is great interest in how much global and local sea level will change in the forthcoming decades. The Paris Climate Agreement's proposed temperature thresholds of 1.5°C and 2°C have directed the research community to ask what differences occur in the climate system for these two states. We have developed a novel approach to combine climate model outputs that follow specific temperature pathways to make probabilistic projections of sea-level in a 1.5°C and 2°C world. We find median global sea-level (GSL) projections for 1.5°C and 2°C temperature pathways of 44 and 50 cm, respectively. The 90% uncertainty ranges (5%-95%) are both around 48 cm by 2100. In addition, we take an alternative approach to estimate the contribution from ice sheets by using a semi-empirical GSL model. Here we find median projections of 58 and 68 cm for 1.5°C and 2°C temperature pathways. The 90% uncertainty ranges are 67 and 82 cm respectively. Regional projections show similar patterns for both temperature pathways, though differences vary between the median projections (2-10 cm) and 95th percentile (5-20 cm) for the bulk of oceans using process-based approach and 10-15 cm (median) and 15-25 cm (95th percentile) using the semi-empirical approach.

Priority substances in combined sewer overflows: case study of the Paris sewer network.

This study was undertaken to supply data on both priority pollutant (PP) occurrence and concentrations in combined sewer overflows (CSOs). A single rain event was studied on 13 sites within the Paris sewer network. For each sample, a total of 66 substances, including metals, polycyclic aromatic hydrocarbons (PAHs), pesticides, organotins, volatile organic compounds, chlorobenzenes, phthalates and alkylphenols were analyzed. Of the 66 compounds analyzed in all, 40 PPs including 12 priority hazardous substances were detected in CSOs. As expected, most metals were present in all samples, reflecting their ubiquitous nature. Chlorobenzenes and most pesticides were never quantified above the limit of quantification, while the majority of the other organic pollutants, except DEHP (median concentration: 22 μg.l(-1)), were found to lie in the μg.l(-1) range. For the particular rain event studied, the pollutant loads discharged by CSOs were evaluated and then compared to pollutant loads conveyed by the Seine River. Under the hydraulic conditions considered and according to the estimations performed, this comparison suggests that CSOs are potentially significant local source of metals, PAHs and DEHP. Depending on the substance, the ratio between the CSO and Seine River loads varied from 0.5 to 26, underscoring the important local impact of CSOs at the scale of this storm for most pollutants.

Increasingly frequent severe coral bleaching is among the greatest threats to coral reefs posed by climate change. Global climate models (GCMs) project great spatial variation in the timing of annual severe bleaching (ASB) conditions; a point at which reefs are certain to change and recovery will be limited. However, previous model-resolution projections (~1 × 1°) are too coarse to inform conservation planning. To meet the need for higher-resolution projections, we generated statistically downscaled projections (4-km resolution) for all coral reefs; these projections reveal high local-scale variation in ASB. Timing of ASB varies >10 years in 71 of the 87 countries and territories with >500 km2 of reef area. Emissions scenario RCP4.5 represents lower emissions mid-century than will eventuate if pledges made following the 2015 Paris Climate Change Conference (COP21) become reality. These pledges do little to provide reefs with more time to adapt and acclimate prior to severe bleaching conditions occurring annually. RCP4.5 adds 11 years to the global average ASB timing when compared to RCP8.5; however, >75% of reefs still experience ASB before 2070 under RCP4.5. Coral reef futures clearly vary greatly among and within countries, indicating the projections warrant consideration in most reef areas during conservation and management planning.

To assess the dietary intake and the nutritional status of homeless men. A night emergency shelter in Paris, France. Dietary survey (48-h) including alcohol intake and a questionnaire on age, duration of homelessness, smoking habits. Subjects were also weighed and measured. Ninety-seven men aged 18-72 years (mean 43.3), of whom 54% were homeless for more than 18 months, 82% were smokers and 53% were regular and/or excessive drinkers. The BMI distribution was shifted towards low values, the percentage of wasted persons being four times higher than in the reference population. The mean total energy intake was 2376 kcal and included a high and highly variable percentage of energy derived from alcohol (12.0% Among drinkers, the mean ethanol intake was 90 g and there was a significant negative correlation between ethanol and non-alcoholic energy intakes. The median intakes of potassium, calcium, zinc, vitamins B1, B2, and niacin were lower than European Population Reference Intakes but only the mean intake of vitamin B1 was significantly lower. Eighty percent of non-alcoholic energy was provided by charitable organisations. For most nutrients, the nutritional density of the shelter ration was not significantly different from the density of the foods purchased by the homeless. These data suggest that the content of some nutrients should be increased in existing food assistance programs for homeless people in France.

Volatile Organic Compounds (VOC) affect urban air quality and regional climate change by contributing to ozone formation and the build-up of Secondary Organic Aerosols (SOA). Quantification of VOC emissions is a first critical step to predict VOC environmental impacts and to design effective abatement strategies. Indeed, the quality of ozone and SOA forecasts strongly depends on an accurate knowledge of the primary VOC emissions. However, commonly used bottom-up approaches are highly uncertain due to source multiplicity (combustion processes, storage and distribution of fossil fuels, solvent use, etc.) because of numerous controlling factors (driving conditions, fuel type, temperature, radiation, etc.), and their great variability in time and space. Field observations of VOC and other trace gases can provide valuable top-down constraints to evaluate VOC emission inventories at urban scales. In addition, the implementation of emission reduction measures raises the question of the increasing importance of VOC sources other than traffic. Here, we will evaluate VOC emissions of two mid-latitude megacities in the Northern Hemisphere: the Greater Paris area (Europe) and Los Angeles (USA). In 2009 and 2010, three intensive field campaigns took place in Paris and Los Angeles in the framework of the MEGAPOLI (EU FP7) and CalNex-2010 projects, respectively. Very detailed measurements of aerosol composition and properties, and their gaseous VOC precursors were carried out at ground-based sites (urban center and suburban) and on various mobile platforms. This contribution uses a comprehensive suite of VOC measurements collected by GC-MS/FID techniques at ground-based sites in both cities by a source-receptor methodology. First, emission ratios were estimated from the observations (uncertainty of ± 20%) and compared regarding regional characteristics and European vs. Californian control policies. Then, determined emission ratios were used to assess the accuracy of up

Plaster of Paris implants containing vancomycin (60 mg/g of carrier) were prepared in order to be used as local delivery system for the treatment of bone infections. The regulation of the release rate was performed by coating the carrier with a polylactide-co-glycolide polymer composed by 10% (w/w) polyglycolic acid and 90% (w/w) racemic poly (D,L-lactic acid). The release of the antibiotic from the biodegradable matrix was evaluated in vitro. From this investigation, it is clear that the drug elution depends on the coating depth. After a burst effect occurring on the first day of the experiment, therapeutic concentrations were measured during one week when uncoated implants were used. The coating allowed decrease of the burst effect and extended efficient release to more than five weeks when the implants were embedded with six layers (162 microns) of PLA45GA10. This delivery system was implanted into the femoral condyle of rabbits. It was shown that the in vivo release was also closely regulated by the coating depth. In all bone tissues (bone marrow and cortical bone) surrounding the pellets, the drug concentration exceeded the Minimum Inhibitory Concentration for the common causative organisms of bone infections (Staphylococcus aureus) for at least four weeks without inducing serum toxic levels. Due to its cheapness, facility of use and sterilization, biocompatibility and biodegradability, plaster of Paris coated with PLA45GA10 polymer giving a controlled release of vancomycin appears to be a promising sustained release delivery system of antibiotics for the treatment of bone and joint infections.

Thirteen Liassic sedimentary rocks of increasing depth and three petroleums from the Paris Basin were studied for 13C/12C isotopic compositions and biological markers, including steranes, sterenes, methylphenanthrenes, methylanthracenes, and triaromatic steroids. The isotopic compositions of n-alkanes from mature sedimentary rocks and petroleums fall in a narrow range (2%), except for the deepest Hettangian rock and the Trias petroleum, for which the short-chain n-alkanes are enriched and depleted in 13C, respectively. Most of the molecular parameters increase over the 2000-2500 m depth range, reflecting the transformation of the organic matter at the onset of petroleum generation. In this zone, carbonate content and carbon isotopic composition of carbonates, as well as molecular parameters, are distinct for the Toarcian and Hettangian source rocks and suggest a migration of organic matter from these two formations. Two novel molecular parameters were defined for this task: one using methyltriaromatic steroids from organic extracts; the other using 1-methylphenanthrene and 2-methylanthracene from kerogen pyrolysates. The anomalous high maturity of the Dogger petroleum relative to the maturity-depth trend of the source rocks is used to estimate the minimal vertical distance of migration of the organic matter from the source rock to the reservoir.

The main purpose of urine cytology is to detect high-grade urothelial carcinoma. With this principle in mind, The Paris System (TPS) Working Group, composed of cytopathologists, surgical pathologists, and urologists, has proposed and published a standardized reporting system that includes specific diagnostic categories and cytomorphologic criteria for the reliable diagnosis of high-grade urothelial carcinoma. This paper outlines the essential elements of TPS and the process that led to the formation and rationale of the reporting system. TPS Working Group, organized at the 2013 International Congress of Cytology, conceived a standardized platform on which to base cytologic interpretation of urine samples. The widespread dissemination of this approach to cytologic examination and reporting of urologic samples and the scheme's universal acceptance by pathologists and urologists is critical for its success. For urologists, understanding the diagnostic criteria, their clinical implications, and limitations of TPS is essential if they are to utilize urine cytology and noninvasive ancillary tests in a thoughtful and practical manner. This is the first international/inclusive attempt at standardizing urinary cytology. The success of TPS will depend on the pathology and urology communities working collectively to improve this seminal paradigm shift, and optimize the impact on patient care.

Sea-level rise is a major consequence of climate change that will continue long after emissions of greenhouse gases have stopped. The 2015 Paris Agreement aims at reducing climate-related risks by reducing greenhouse gas emissions to net zero and limiting global-mean temperature increase. Here we quantify the effect of these constraints on global sea-level rise until 2300, including Antarctic ice-sheet instabilities. We estimate median sea-level rise between 0.7 and 1.2 m, if net-zero greenhouse gas emissions are sustained until 2300, varying with the pathway of emissions during this century. Temperature stabilization below 2 °C is insufficient to hold median sea-level rise until 2300 below 1.5 m. We find that each 5-year delay in near-term peaking of CO 2 emissions increases median year 2300 sea-level rise estimates by ca. 0.2 m, and extreme sea-level rise estimates at the 95th percentile by up to 1 m. Our results underline the importance of near-term mitigation action for limiting long-term sea-level rise risks.

A program for helping homeless individuals in winter is implemented from November 1(st) to March 31(st) each year in France. Its aim is to prevent morbidity and mortality in this population during cold spells and periods of severe cold. A health surveillance system of the homeless population in the Paris area has been proposed to evaluate the effectiveness of the program and to alert decision-makers if an unusual increase in cold-weather effects is observed. The goal of this study was the creation of an indicator for the proposed surveillance system based on emergency department activity in the Paris area (Oscour(®) Network - Organisation de la surveillance coordonnée des urgences). The winter 2007-2008 computer medical files of 11 emergency departments in the Paris area were examined to confirm diagnosis and ascertain patient-homelessness for each patient visit which was selected from the Oscour(®) database by the patient chief-complaint or diagnosis code referring to hypothermia or frostbites. The proposed indicator is based on the maximization of three criteria: the positive predictive value, the proportion of people identified as being homeless and the number of emergency department visits. A Shewhart control chart was applied to the indicator for the four winters between 2005 and 2009 in the Paris area. Values beyond the statistical threshold would indicate a need for an adjustment to the program strategy. Two hundred and sixteen medical files were analyzed. An indicator was created, "number of emergency department visits of 15 to 69-years-old persons with chief-complaint or diagnosis code referring to hypothermia". It had a positive predictive value estimated near 85 % and identified 61.7 % people as being homeless. In the winter of 2008-2009, the statistical threshold was reached in December during the first cold spell, and again at the beginning of January during a period of severe cold. Our results support the use of this health indicator

Recent studies have examined sleep health among men who have sex with men (MSM), but no studies have examined associations of neighborhood characteristics and sleep health among this population. The purpose of this study was to examine associations between perceived neighborhood safety and sleep health among a sample of MSM in Paris, France. We placed broadcast advertisements on a popular smartphone application for MSM in October 2016 to recruit users in the Paris (France) metropolitan area (n = 580). Users were directed to complete a web-based survey, including previously used items measuring perceptions of neighborhood safety, validated measures of sleep health, and socio-demographics. Modified Poisson models were used to estimate risk ratios (RRs) and 95% confidence intervals (CI) for the associations between perceived neighborhood safety and the following outcomes: (1) poor sleep quality, (2) short sleep duration, and (3) self-reported sleep problems. Poor sleep health was common in our sample; e.g., 30.1% reported poor sleep quality and 44.7% reported problems falling asleep. In multivariate regression models, perceived neighborhood safety was associated with poor sleep quality, short sleep duration, and having sleep problems. For example, reporting living in a neighborhood perceived as unsafe during the daytime (vs. safe) was associated with poor sleep quality (aRR, 1.60; 95% CI, 1.01, 2.52), short sleep duration (aRR, 1.92; 95% CI, 1.26, 2.94), problems falling asleep (aRR, 1.57; 95% CI, 1.17, 2.11), and problems staying awake in the daytime (aRR, 2.16; 95% CI, 1.05, 4.43). Interventions to increase neighborhood safety may improve sleep health among MSM.

National baselines for the Sustainable Development Goals assessed in the SDG Index and Dashboards

The Sustainable Development Goals (SDGs) -- agreed in 2015 by all 193 member states of the United Nations and complemented by commitments made in the Paris Agreement -- map out a broad spectrum of economic, social and environmental objectives to be achieved by 2030. Reaching these goals will require deep transformations in every country, as well as major efforts in monitoring and measuring progress. Here we introduce the SDG Index and Dashboards as analytical tools for assessing countries' baselines for the SDGs that can be applied by researchers in the cross-disciplinary analyses required for implementation. The Index and Dashboards synthesize available country-level data for all 17 goals, and for each country estimate the size of the gap towards achieving the SDGs. They will be updated annually. All 149 countries for which sufficient data is available face significant challenges in achieving the goals, and many countries' development strategies are imbalanced across the economic, social and environmental priorities. We illustrate the analytical value of the index by examining its relationship with other widely used development indices and by showing how it accounts for cross-national differences in subjective well-being. Given significant data gaps, scope and coverage of the Index and Dashboards are limited, but we suggest that these analyses represent a starting point for a comprehensive assessment of national SDG baselines and can help policymakers determine priorities for early action and monitor progress. The tools also identify data gaps that must be closed for SDG monitoring.

Continuous mapping of an ozone episode in Paris in June 1999 has been performed using a differential absorption lidar system. The 2D ozone concentration vertical maps recorded over 33 h at the Champ de Mars are compiled in a video clip that gives access to local photochemical dynamics with unprecedented precision. The lidar data are compared over the whole period with point monitors located at 0-, 50-, and 300-m altitudes on the Eiffel Tower. Very good agreement is found when spatial resolution, acquisition time, and required concentration accuracy are optimized. Sensitivity to these parameters for successful intercomparison in urban areas is discussed.

This article provides data on the contamination of different kinds of sludge (raw, centrifuged, digested, thermally dried sludge and sludge cake) from Paris conurbation by 71 various pollutants including pharmaceutical products (PHPs), hormones, perfluorinated acids (PFAs), linear alkylbenzene sulfonate (LAS), alkylphenols (APs), phthalates (PAEs), polycyclic aromatic hydrocarbons (PAHs) and polychlorobiphenyls (PCBs). Very high contents of LAS (0.1-10g/kg dry matter - DM) compared to other compounds were found in all types of sludge followed by DEHP (10-100mg/kg DM) and fluoroquinolones (1-100mg/kg DM). APs were measured at intermediary contents in Parisian sludge, lying in the 2-20mg/kg DM range. Finally, hormones, PAHs, PCBs, PAEs, PFAs and the remaining PHPs were all found at contents lower than 1mg/kg DM. For most compounds (PHPs, PFOS, DEHP, PAHs), no significant differences in the micropollutant contents were found for similar types of sludge from different WWTP in Paris, highlighting the homogeneity of sludge contamination in downstream Paris catchment. The variability of concentration is rather high (coefficient of variation >100%) for several PHPs, PFAs or PCBs while it is moderate (<100%) or low (<50%) for fluoroquinolones, hormones, PAHs, APs or LAS. In addition, digestion seems to have a buffer effect as variabilities are lower in digested sludge for PHPs, PFAs, APs and PCBs. During sludge treatment (centrifugation, digestion, thermal drying, sludge conditioning+press filtration), the hormones, LAS, APs, PAHs, DEHP and PCBs concentrations increased, while those of PHPs and PFAs decreased. In the case of digestion, the increase of content can be explained by no pollutant removal or a lower removal than DM removal (concentration phenomenon) whereas the decrease underlines that the compound is more removed than the DM. In any case, these concentration variations presuppose the mechanisms of dissipation that could be attributed to volatilization, biotic or

The human body louse is the only known vector of Bartonella quintana. However, the presence of this bacterium has recently been detected in the head lice of homeless individuals and Nepalese slum children. Previous studies have reported the isolation of Acinetobacter baumannii from the body lice of homeless individuals. An epidemiological survey including 74 schools was conducted between 2008 and 2009 in Paris. After a first visual examination, the hair of children with suspected pediculosis was combed with a fine-tooth comb to collect live adult head lice. Molecular studies were performed on randomly selected DNA samples to detect B. quintana and A. baumannii by specific quantitative real-time PCR. Among a collection of 288 DNA samples, B. quintana was not detected, but A. baumannii was detected in 95 DNA samples (33%). Further study is needed to determine the significance of the finding of A. baumannii in head lice. 2011. Published by Elsevier Ltd. All rights reserved.

Direct oral anticoagulants (DAOC) are indicated for the treatment of venous thromboembolism and the prevention of stroke or systemic embolism in patients with non-valvular atrial fibrillation. Given their advantages and friendly use for patient, the prescription of long term DOAC therapy has rapidly increased both as first line treatment while initiating anticoagulation and as a substitute to vitamins K antagonist (VKA) in poorly controlled patients. However, DOAC therapy can also be associated with significant bleeding complications, and in the absence of specific antidote at disposal, treatment of serious hemorrhagic complications under DOAC remains complex. We report and discuss herein five cases of major hemorrhagic complications under DOAC, which were reported to the pharmacological surveillance department over one year at Saint-Louis University Hospital (Paris, France). We further discuss the need for careful assessment of the risk/benefit ratio at time of starting DOAC therapy in daily clinical practice. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

[Should we teach bioethics to students in dentistry as part of public studies? An example in the Faculty of Dentistry at the University Paris Descartes].

Pirnay, P

The dental student is committed to being an actor in public health and his/her mission must deal with the wishes of the patient and the ethical requirements of the society. In order to improve physical and mental health on an individual and collective level, the University has a responsibility to develop a real culture of public health early in the academic curriculum. This context raises the question of the usefulness of ethics education for students in dental school. The Faculty of Dentistry at Paris Descartes University is engaged in a pilot process to reform dental studies, taking into account official and ministerial directives. An educational program on ethics delivered during the course of 10 semesters is broken down into lectures, practical lessons, and active training in one of four Paris hospitals. Teaching bioethics in the public health context puts the student at the center of an active process where each student is responsible for personal involvement in five proposed teaching methods: lectures, seminars, directed education, and reference research using the University's intranet portal. The result of 3 years of experience teaching bioethics in public health discipline is positive. The dental students are encouraged to develop skills to analyze an effective strategy for dental care where ethics becomes a cardinal value. In this sense, the teaching of bioethics that is at the heart of public debates is perfectly adapted to the public health discipline. Ultimately, it could be integrated into the teaching of all subjects. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

The role of anthropogenic aerosol emission reduction in achieving the Paris Agreement's objective

The Paris agreement reached in December 2015 under the auspices of the United Nation Framework Convention on Climate Change (UNFCCC) aims at holding the global temperature increase to well below 2◦C above preindustrial levels and "to pursue efforts to limit the temperature increase to 1.5◦C above preindustrial levels". Limiting warming to any level implies that the total amount of carbon dioxide (CO2) - the dominant driver of long-term temperatures - that can ever be emitted into the atmosphere is finite. Essentially, this means that global CO2 emissions need to become net zero. CO2 is not the only pollutant causing warming, although it is the most persistent. Short-lived, non-CO2 climate forcers also must also be considered. Whereas much effort has been put into defining a threshold for temperature increase and zero net carbon emissions, surprisingly little attention has been paid to the non-CO2 climate forcers, including not just the non-CO2 greenhouse gases (methane (CH4), nitrous oxide (N2O), halocarbons etc.) but also the anthropogenic aerosols like black carbon (BC), organic carbon (OC) and sulfate. This study investigates the possibility of limiting the temperature increase to 1.5◦C by the end of the century under different future scenarios of anthropogenic aerosol emissions simulated with the very simplistic MAGICC climate carbon cycle model as well as with ECHAM6.1-HAM2.2-SALSA + UVic ESCM. The simulations include two different CO2 scenarios- RCP3PD as control and a CO2 reduction leading to 1.5◦C (which translates into reaching the net zero CO2 emissions by mid 2040s followed by negative emissions by the end of the century); each CO2 scenario includes also two aerosol pollution control cases denoted with CLE (current legislation) and MFR (maximum feasible reduction). The main result of the above scenarios is that the stronger the anthropogenic aerosol emission reduction is, the more significant the temperature increase by 2100 relative to pre

Politicians, government officials, business representatives, and nongovernmental climate activists all in various ways emphasize what they see as progress being made in the aftermath of the Paris Agreement, even if they continue to warn of the dire consequences of business as usual. Indeed, there is no lack of encouraging private and public sector initiatives on climate change. Some macro trends seem to be moving in the right direction, as well. But, closer scrutiny shows that these positive trends are still far from adding up to the necessary fundamental shift in the global energy economy. Furthermore, the public may greatly overestimate the advancement of renewable solar and wind energy technology, which contributes to a false sense of progress and lessens political urgency. Without determined and reinvigorated political leadership from the European Union (EU), there is little hope that necessary emission reduction goals to stay below 2 °C above preindustrial levels can be met. The EU has driven international climate policy from the beginning of climate negotiations, and there is unfortunately no other source of leadership in sight. It will require difficult political decisions to be taken sooner rather than later to force a much quicker domestic energy transition and to raise financing to help developing countries with their own energy transition and adaptation to a rapidly warming world.

Jatropha curcas L. is an inedible plant belonging to the Euphorbiaceae family that is growing in subtropical zones of all continents. We report a series of 24 cases of poisoning with J. curcas seeds or fruits reported to poison centers in Paris and Marseille between December 2000 and June 2014. Fifteen adults and 9 children ingested J. curcas seeds or fruits. All patients experienced gastrointestinal disorders, within the first hours following ingestion: nausea, vomiting, diarrhea and abdominal pain. Laboratory investigations performed in 10 patients revealed minor abnormalities: CK elevation (8 cases), dehydration (5 cases) with moderate elevation of serum creatinine levels (3 cases), and mildly increased serum bilirubin (8 cases). Complete remission of all clinical signs was observed within 48 hours in the 20 cases for which the outcome was known. Previously published cases of J. curcas poisoning were very similar to ours: As in our series, gastrointestinal disorders were always present. They were sometimes associated with neurological or cardiovascular signs, and hepatic or renal disorders; these were generally interpreted as complications of severe gastroenteritis, although direct toxic effects could not be formally excluded. In most cases, simple supportive measures were sufficient to ensure complete recovery within 24-48 hours. J Curcas poisoning incidence is certainly increasing because the plant is cultivated to produce biodiesel and is now largely present in most subtropical countries. As a consequence, local health professionals should be informed of the toxic properties of this plant.

Pisgah Astronomical Research Institute (PARI), a former NASA tracking station located in western North Carolina, has been offering programs, campus, and instrument use for undergraduate research and learning experiences since 2000. Over these years, PARI has collaborated with universities and colleges in the Southeastern U.S. Sharing its campus with institutions of higher learning is a priority for PARI as part of its mission to "to providing hands-on educational and research opportunities for a broad cross-section of users in science, technology, engineering and math (STEM) disciplines."PARI is a 200 acre campus for environmental, earth, geological, physical, and astronomical sciences. For example, the PARI 26-m and 4.6-m radio telescopes are excellent for teaching electromagnetic theory, spectroscopy, atomic and molecular emission processes, and general physics and astronomy concepts. The PARI campus has lab and office space, data centers with high speed internet, distance learning capabilities, radio and optical telescopes, earth science sensors, housing and cafeteria.Also, the campus is in an excellent spot for environmental and biological sciences lab and classroom experiences for students. The campus has the capability to put power and Internet access almost anywhere on its 200 acre campus so experiments can be set up in a protected area of a national forest. For example, Earthscope operates a Plate Boundary Observatory sensor on campus to measure plate tectonic motion. And, Clemson University has an instrument measuring winds and temperatures in the Thermsophere. The use of thePARI campus is limited only by the creativity faculty to provide a rich educational environment for their students. An overview of PARI will be presented along with a summary of programs, and a summary of undergraduate research experiences over the past 15 years. Access to PARI and collaboration possibilities will be presented.

The aim of this study was to describe the characteristics of out-of-hospital cardiac arrest (OHCA) in different workplaces, their management, and the survival rate. A post hoc analysis included all the OHCA cases that occurred at the workplace and were listed in the Fire Brigade of Paris database registry (2010 to 2014). Utstein-style variables, survival, and types of workplace were analyzed. The study included 298 OHCA cases, mostly young (44% between 18 and 50 years), male (86%), and nontraumatic (86%). Differences in the survival chain were found to be related to the types of work location: bystander cardiopulmonary resuscitation was performed in 0% to 55% of cases, and workplace-automated external defibrillators were used in 0% to 20% of cases. Long-term survival without major incapacity was 0% to 23%. The characteristics of OHCA differ as a function of the type of workplace.

Globally, $2.5tn a year is spent on infrastructure which is typically designed to last decades, over which period projected changes in the climate will modify infrastructure performance. A systems approach has been developed to assess risks across all infrastructure sectors to guide national policy making and adaptation investment. The method analyses diverse evidence of climate risks and adaptation actions, to assess the urgency and extent of adaptation required. Application to the UK shows that despite recent adaptation efforts, risks to infrastructure outweigh opportunities. Flooding is the greatest risk to all infrastructure sectors: even if the Paris Agreement to limit global warming to 2°C is achieved, the number of users reliant on electricity infrastructure at risk of flooding would double, while a 4°C rise could triple UK flood damage. Other risks are significant, for example 5% and 20% of river catchments would be unable to meet water demand with 2°C and 4°C global warming respectively. Increased interdependence between infrastructure systems, especially from energy and information and communication technology (ICT), are amplifying risks, but adaptation action is limited by lack of clear responsibilities.

Processed fibers are highly present in our daily life and can be either natural, artificial (regenerated cellulose) and synthetic (made with petrochemicals). Their widespread use lead inevitably to a high contamination of environment. Previous studies focus on plastic particles regardless of their type or shape as long as they are comprised between 330μm and 5mm. On the contrary, this study focuses exclusively on fibers using a smaller mesh size net (80μm) to sample freshwater. Moreover, all processed organic fibers are considered, irrespective to their nature. First, the short term temporal variability of the fibers in the environment was assessed. While exposing the sampling net during 1min a coefficient of variation of approx. 45% (with n=6) was determined. It was of only 26% (n=6) when the exposure was of 3min. The assessment of the distribution through the section showed a possible difference in concentrations between the middle of the water surface and the river banks which could be attributed to the intense river traffic within the Paris Megacity. The vertical variability seems negligible as turbulence and current conditions homogenize the distribution of the fibers. A monthly monitoring showed concentrations of 100.6±99.9fibers·m -3 in the Marne River and of: 48.5±98.5, 27.9±26.3, 27.9±40.3 and 22.1±25.3fibers·m -3 from the upstream to downstream points in the Seine River. Once these concentrations are converted into fluxes, it seems that the impact generated by the Paris Megacity cannot be distinguished. Investigations on the role of sedimentation and deposition on the banks are required. This study helped fill some major knowledge gaps regarding the fibers in rivers, their sampling, occurrence, spatial-temporal distribution and fluxes. It is encouraged that future studies include both synthetic and none synthetic fibers. Copyright © 2017 Elsevier B.V. All rights reserved.

Sea-level rise (SLR) is magnifying the frequency and severity of flooding in coastal regions. The rate and amount of global-mean SLR is a function of the trajectory of the global mean surface temperature (GMST). Therefore, temperature stabilization targets (e.g., 1.5°C or 2°C, as from the Paris Agreement) have important implications for regulating coastal flood risk. Quantifying the differences in the impact from SLR between these and other GMST stabilization targets is necessary for assessing the benefits and harms of mitigation goals. Low-lying small island nations are particularly vulnerable to inundation and coastal flooding from SLR because building protective and resilient infrastructure may not be physically or economically feasible. For small island nations, keeping GMST below a specified threshold may be the only option for maintaining habitability. Here, we assess differences in the return levels of coastal floods for small island nations between 1.5°C, 2.0°C, and 2.5°C GMST stabilization. We employ probabilistic, localized SLR projections and long-term hourly tide gauge records to construct estimates of local flood risk. We then estimate the number of small island nations' inhabitants at risk for permanent inundation under different GMST stabilization targets.

Dressing religious bodies in public spaces: gender, clothing and negotiations of stigma among Jews in Paris and muslims in London.

In recent years religious clothing has become prevalent across many European cities, making religious bodies more visible in public spaces. This paper brings together our separate research on Jews in Paris and Muslims in London. While recognising the clear differences between these two socio-political contexts and distinct religious groups, we suggest that a focus on clothing allows us to consider some points of similarity and difference in the presentation of gendered religious bodies, particularly in situations of heightened stigmatisation. We draw upon Goffman's notion of impression management, in contexts of risks and threats, to explore how individuals experience and negotiate self presentation as members of stigmatised religious groups. We use rich qualitative data based on indepth interviews to consider how, when faced with collective stigmatisation, actors make deliberate and measured choices to present themselves and attempt to impression manage.

The king's animals and the king's books: the illustrations for the Paris Academy's Histoire des animaux.

Guerrini, Anita

2010-07-01

This essay explores the place of natural philosophy among the patronage projects of Louis XIV, focusing on the Mémoires pour servir a l'histoire naturelle des animaux (or Histoire des animaux) of the 1670s, one of a number of works of natural philosophy to issue from Louis XIV's printing house. Questions particular to the Histoire des animaux include the interaction between text and image, the credibility and authority of images of exotic animals, and the relationship between comparative anatomy and natural history, and between human and animal anatomy. At the same time that the Histoire des animaux contributed to Jean-Baptiste Colbert's management of patronage and of Louis's image, it was a work of natural philosophy, representing the collaborative efforts of the new Paris Academy of Sciences. It examined natural history and comparative anatomy in new ways, and its illustrations broke new ground in their depiction of animals in a natural setting. However, the lavishly formatted books were presentation volumes and did not gain wide circulation until their republication in 1733. Sources consulted include Colbert's manuscript memoires on the royal printers and engravers.

Pseudo-radar algorithms with two extremely wet months of disdrometer data in the Paris area

Disdrometer data collected during the two extremely wet months of May and June 2016 at the Ecole des Ponts ParisTech are used to get insights on radar algorithms. The rain rate and pseudo-radar quantities (horizontal and vertical reflectivity, specific differential phase shift) are all estimated over several durations with the help of drop size distributions (DSD) collected at 30 s time steps. The pseudo-radar quantities are defined with simplifying hypotheses, in particular on the DSD homogeneity. First it appears that the parameters of the standard radar relations Zh - R, R - Kdp and R - Zh - Zdr for these pseudo-radar quantities exhibit strong variability between events and even within an event. Second an innovative methodology that relies on checking the ability of a given algorithm to reproduce the good scale invariant multifractal behaviour (on scales 30 s - few h) observed on rainfall time series is implemented. In this framework, the classical hybrid model (Zh - R for low rain rates and R - Kdp for great ones) performs best, as well as the local estimates of the radar relations' parameters. However, we emphasise that due to the hypotheses on which they rely these observations cannot be straightforwardly extended to real radar quantities.

In view of the negative forcing of the sulfate aerosols on climate, a more accurate understanding of the formation of these particles is crucial. Indeed, despite the knowledge of their effects, uncertainties remain regarding the formation of sulfate aerosols, particularly the oxidation processes of S-bearing gases. Since the discovery of oxygen and sulfur mass independent fractionation (O- and S-MIF) processes on Earth, the sulfate isotopic composition became essential to investigate the atmospheric composition evolution and its consequences on the climate and the biosphere. Large amount of S-bearing compounds (SO2 mainly) is released into the atmosphere by anthropogenic and natural sources. Their oxidation in the atmosphere generates sulfate aerosols, H2SO4, which precipitate on the earth surface mainly as acid rain. One consequence of this precipitation is the formation of black crust on buildings made of carbonate stones. Indeed the chemical alteration of CaCO3 by H2SO4 leads to gypsum (CaSO4·2H2O) concretions on building walls. Associated to other particles, gypsum forms black-crusts. Therefore, black crusts acts as 'sulfate aerosol traps', meaning that their isotopic composition reveals the composition and thus the source and formation processes of sulfate aerosols in the atmosphere in a specific region. In this study we collected 37 black crusts on a 300km NW-SE profile centered on Paris (France). In our samples, sulfate represent 40wt.% and other particles 60wt.% of the black crusts. After sulfate extraction from each samples we measured their O- and S-isotopes composition. Variations of about 10‰ in δ18O and δ34S are observed and both O-MIF (Δ17O from 0 to 1.4‰) and S-MIF (Δ33S from 0 to -0.3‰) compositions have been measured. In regards to these compositions we can discuss the source and formation (oxidation pathways) of the sulfate aerosols in troposphere above the Paris region that covers urban, rural and coastal environments.

The End-Triassic mass-extinction event is one of the "big five" mass extinctions in Earth's history. Large scale flood basalt volcanism associated with the break-up of Pangaea, which resulted in the opening of the central Atlantic Ocean, is considered as the leading cause. In addition, an asteroid impact in Rochechouart (France; 201 ± 2 Ma) may have had a local influence on ecosystems and sedimentary settings. The Luxembourg Embayment, in the NE Paris Basin, offers a rare chance to study both effects in a range of settings from deltaic to lagoonal. A multidisciplinary study (sedimentology, geochemistry, palynology) has been carried out on a number of outcrops and cores that span from the Norian to lower Hettangian. Combined geochemical and palynological records from the Boust core drilled in the NE Paris Basin, provide evidence for paleoenvironmental changes associated with the end-Triassic mass-extinction event. The Triassic-Jurassic stratigraphy of the Boust core is well constrained by palynomorphs showing the disappaerance of typical Triassic pollen taxa (e.g. Ricciisporites tuberculates) and the occurrence of the marker species Polypodiisporites polymicroforatus within the uppermost Rhaetian, prior to the Hettangian dominance of Classopollis pollen. The organic carbon stable isotope record (δ13Corg) spanning the Norian to Hettangian, shows a series of prominent negative excursions within the middle Rhaetian, followed by a trend towards more positive values (approx -24 per mille) within the uppermost Rhaetian Argiles de Levallois Member. The lowermost Hettangian is characterized by a major negative excursion, reaching - 30 per mille that occurs in organic-rich sediments. This so-called "main negative excursion" is well-known from other locations, for example from Mariental in Northern Germany and from St Audrie's Bay in England, and Stenlille in Denmark. Based on redox-sensitive trace element records (V, Cr, Ni, Co, Th, U) the lowermost Hettangian in most of

Paris yunnanensis is a kind of rare medicinal herb, having a very high medicinal value. Studying its suitable ecological condition can provide a basis for its rational exploitation, artificial cultivation, and sustainable utilization. A practicable method in this paper has been proposed to research the suitable regional distribution of P. yunnanensis in Sichuan province. By the case study of P. yunnanensis in Sichuan province, and according to related literatures, the suitable ecological condition of P. yunnanensis such as altitude, mean annual temperature (MAT), annual precipitation, regional slope, slope ranges, vegetative cover, and soil types was analyzed following remote sensing (RS) and GIS.The appropriate distribution regionof P. yunnanensis and its area were extracted based on RS and GIS technology,combing with the information of the field validation data. The results showed that the concentrated distribution regions in counties of Sichuan province were, Liangshan prefecture, Aba prefecture, Sertar county of Ganzi prefecture, Panzhihua city, Ya'an city, Chengdu city, Meishan city, Leshan city, Yibin city, Neijiang city, Luzhou city, Bazhong city, Nanchong city, Guangyuan city and other cities and counties area.The suitable distribution area in Sichuan is about 7 338 km², accounting for 3.02% of the total study regional area. The analysis result has high consistency with the filed validation data, and the research method for P. yunnanensis distribution region based onspatial overlay analysis and the extracted the information of land usage and ecological factors following the RS and GIS is reliable.

Airborne mineral components and trace metals in Paris region: spatial and temporal variability.

A variety of mineral components (Al, Fe) and trace metals (V, Cr, Mn, Ni, Cu, Zn, Cd, Pb) were simultaneously measured in PM2.5 and PM10 fractions at three different locations (traffic, urban, and suburban) in the Greater Paris Area (GPA) on a daily basis throughout a year. Mineral species and trace metal levels measured in both fractions are in agreement with those reported in the literature and below the thresholds defined by the European guidelines for toxic metals (Cd, Ni, Pb). Size distribution between PM2.5 and PM10 fractions revealed that mineral components prevail in the coarse mode, while trace metals are mainly confined in the fine one. Enrichment factor analysis, statistical analysis, and seasonal variability suggest that elements such as Mn, Cr, Zn, Fe, and Cu are attributed to traffic, V and Ni to oil combustion while Cd and Pb to industrial activities with regional origin. Meteorological parameters such as rain, boundary layer height (BLH), and air mass origin were found to significantly influence element concentrations. Periods with high frequency of northern and eastern air masses (from high populated and industrialized areas) are characterized by high metal concentrations. Finally, inner city and traffic emissions were also evaluated in PM2.5 fraction. Significant contributions (>50 %) were measured in the traffic site for Mn, Fe, Cr, Zn, and Cu, confirming that vehicle emissions contribute significantly to their levels, while in the urban site, the lower contributions (18 to 33 %) for all measured metals highlight the influence of regional sources on their levels.

Lipofilling is now performed to improve the breast contour, after both breast-conserving surgery and breast reconstruction. However, injection of fat into a previous tumor site may create a new environment for cancer and adjacent cells. There is also no international agreement regarding lipofilling after breast cancer treatment. The authors included three institutions specializing in both breast cancer treatment and breast reconstruction (European Institute of Oncology, Milan, Italy; Paris Breast Center, Paris, France; and Leon Berard Centre, Lyon, France) for a multicenter study. A collective chart review of all lipofilling procedures after breast cancer treatment was performed. From 2000 to 2010, the authors reviewed 646 lipofilling procedures from 513 patients. There were 370 mastectomy patients and 143 breast-conserving surgery patients. There were 405 patients (78.9 percent) with invasive carcinoma and 108 (21.1 percent) with carcinoma in situ. The average interval between oncologic surgical interventions and lipofilling was 39.7 months. Average follow-up after lipofilling was 19.2 months. The authors observed a complication rate of 2.8 percent (liponecrosis, 2.0 percent). Twelve radiologic images appeared after lipofilling in 119 breast-conserving surgery cases (10.1 percent). The overall oncologic event rate was 5.6 percent (3.6 percent per year). The locoregional event rate was 2.4 percent (1.5 percent per year). Lipofilling after breast cancer treatment leads to a low complication rate and does not affect radiologic follow-up after breast-conserving surgery. A prospective clinical registry including high-volume multicenter data with a long follow-up is warranted to demonstrate the oncologic safety. Until then, lipofilling should be performed in experienced hands, and a cautious oncologic follow-up protocol is advised. Therapeutic, IV [corrected].

How much drinking water can be saved by using rainwater harvesting on a large urban area? application to Paris agglomeration.

This paper is based on a prospective scenario of development of rainwater harvesting (RWH) on a given large urban area (such as metropolitan area or region). In such a perspective, a new method is proposed to quantify the related potential of potable water savings (PPWS) indicator on this type of area by adapting the reference model usually used on the building level. The method is based on four setting-up principles: gathering (definition of buildings-types and municipalities-types), progressing (use of an intermediate level), increasing (choice of an upper estimation) and prioritizing (ranking the stakes of RWH). Its application to the Paris agglomeration shows that is possible to save up to 11% of the total current potable water through the use of RWH. It also shows that the residential sector offers the most important part because it holds two-thirds of the agglomeration PPWS.

Jungnitz, Bernhard

The development of nursing is analysed from the perspective of its situation in Germany today, and the requirements expected for the next years to come. It becomes apparent that nursing as a profession regulated by the state is a young profession, just some one hundred years old. During the 19th century nursing in Germany was mostly performed by sisterhoods bound to the church and organised as collectives. But it was stimulated and challenged by the development from a philosophically oriented library medicine to a scientifically oriented hospital medicine. Thus its transformation into a profession regulated by the state ended for the time being in 1906. Nursing sisterhoods in Germany were modelled for the French Daughters of Charity that had been planted in 1633 by Vincent de Paul and Louise de Marillac in Paris. Models for this planting are pointed to.

We present a short historical review on the major institutions and figures that contributed to make Paris a renowned centre of physiology and neurology during the xixth and the first half of the xxth centuries. We purposely chose to focus on the period 1800-1950, as 1800 corresponds to the development of brain science and 1950 marks the true beginning of neuroscience. Our presentation is divided into four chapters, matching the main disciplines which have progressed and contributed the most to the knowledge we have of the brain sciences: anatomy, physiology, neurology, and psychiatry-psychology. The present article is the first of four parts of this review, which includes an introduction followed by the chapter on neuroanatomy and on anatomo-pathology, which includes biographical sketches of Félix Vicq d'Azyr, François-Xavier Bichat, Franz Joseph Gall, Jean Cruveilhier, Jules Bernard Luys, Paul Broca, Louis Ranvier, André-Victor Cornil, Albert Gombault, Jean Nageotte and René Couteaux.

The Path Forward from Paris: the Challenge for Tropical Countries

NASA Astrophysics Data System (ADS)

Nobre, C.

2016-12-01

The pledges of emissions reductions put forth at the COP21 in Paris fall short of ensuring the desired guardrail of 2 C warming, let alone the more stringent, but necessary, goal of 1.5 C warming if we want to minimize the increasing risks of climate change over both the short term of decades and the long term of centuries. Decarbonization of the global economy is mandatory, which implies a gargantuan challenge of decarbonizing the energy system. Given the likelihood of decreasing strength of the natural sinks in the global oceans and land biota as warming progresses, it may be necessary to reach nearly zero net emissions by midcentury and even negative net emissions by the end of the century. In addition to massive and rapid implementation of renewable energy systems, desirable mitigation trajectories involve large-scale reforestation and ecosystem restoration and also bioenergy capture and storage systems (BECCS). Tropical countries can play an important role to meet both goals as long as they are able to implement sustainable agriculture at the large scale that is nearly carbon-neutral and resilient to unavoidable climate change. And reaching sustainability in the agricultural sector—remembering that agricultural direct emissions and indirect emissions due to deforestation account for almost one quarter of global emissions—is under the constraint to meet food security for all, that is, food production has to grow 70% by midcentury, with concomitant reduction of waste in the food chain. I will take the example of mitigation options for Brazil—a large tropical country with per capita emissions of about 7.5 ton CO2-eq—to illustrate sustainable development trajectories of reaching carbon neutrality by midcentury. That will imply developing a modern, more productive carbon-neutral agriculture within the next two decades, reducing tropical deforestation to nearly zero within a decade, restoring ecosystems and increasing renewable energy use to over 80% of its

The availability of circulating biomarkers that helps to identify early out-of-hospital cardiac arrest survivors who are at increased risk of long-term mortality remains challenging. Our aim was to prospectively study the association between copeptin and 1-year mortality in patients with out-of-hospital cardiac arrest admitted in a tertiary cardiac arrest center. Retrospective monocenter study. Tertiary cardiac arrest center in Paris, France. Copeptin was assessed at admission and day 3. Pre- and intrahospital factors associated with 1-year mortality were analyzed by multivariate Cox proportional analysis. None. Two hundred ninety-eight consecutive out-of-hospital cardiac arrest patients (70.3% male; median age, 60.2 yr [49.9-71.4]) were admitted in a tertiary cardiac arrest center in Paris (France). After multivariate analysis, higher admission copeptin was associated with 1-year mortality with a threshold effect (hazard ratio(5th vs 1st quintile) = 1.64; 95% CI, 1.05-2.58; p = 0.03). Day 3 copeptin was associated with 1-year mortality in a dose-dependent manner (hazard ratio(2nd vs 1st quintile) = 1.87; 95% CI, 1.00-3.49; p = 0.05; hazard ratio(3rd vs 1st quintile) = 1.92; 95% CI, 1.02-3.64; p = 0.04; hazard ratio(4th vs 1st quintile) = 2.12; 95% CI, 1.14-3.93; p = 0.02; and hazard ratio(5th vs 1st quintile) = 2.75; 95% CI, 1.47-5.15; p < 0.01; p for trend < 0.01). For both admission and day 3 copeptin, association with 1-year mortality existed for out-of-hospital cardiac arrest of cardiac origin only (p for interaction = 0.05 and < 0.01, respectively). When admission and day 3 copeptin were mutually adjusted, only day 3 copeptin remained associated with 1-year mortality in a dose-dependent manner (p for trend = 0.01). High levels of copeptin were associated with 1-year mortality independently from prehospital and intrahospital risk factors, especially in out-of-hospital cardiac arrest of cardiac origin.

Cytomegalovirus (CMV) is the most frequent cause of congenital infection. The objective of this study was to evaluate predictive factors for CMV seronegativity in a cohort of pregnant women in Paris, France. Pregnant women enrolled in a prospective cohort during the 2009 A/H1N1 pandemic were tested for CMV IgG antibodies. Variables collected were age, geographic origin, lifestyle, work characteristics, socioeconomic status, gravidity, parity and number of children at home. A multivariate logistic regression model was used to identify independent predictive factors for CMV seropositivity. Among the 826 women enrolled, 389 (47.1%) were primiparous, and 552 (67.1%) had Metropolitan France as a geographic origin. Out of these, 355 (i.e. 57.0%, 95% confidence interval (CI): [53.6%-60.4%]) were CMV seropositive: 43.7% (95% CI:[39.5%-47.9%]) in those whose geographic origin was Metropolitan France and 84.1% in those with other origins (95% CI:[79.2%-88.3%]). Determinants associated with CMV seropositivity in a multivariate logistic regression model were: (i) geographic origin (p<0.001(compared with Metropolitan France, geographic origins of Africa adjusted odds ratio (aOR) 21.2, 95% CI:[9.7-46.5], French overseas departments and territories and other origin, aOR 7.5, 95% CI:[3.9-14.6], and Europe or Asia, aOR 2.2, 95% CI: [1.3-3.7]); and (ii) gravidity (p = 0.019), (compared with gravidity = 1, if gravidity≥3, aOR = 1.5, 95% CI: [1.1-2.2]; if gravidity = 2, aOR = 1.0, 95% CI: [0.7-1.4]). Work characteristics and socioeconomic status were not independently associated with CMV seropositivity. In this cohort of pregnant women, a geographic origin of Metropolitan France and a low gravidity were predictive factors for CMV low seropositivity. Such women are therefore the likely target population for prevention of CMV infection during pregnancy in France.

Out of these, 355 (i.e. 57.0%, 95% confidence interval (CI): [53.6%–60.4%]) were CMV seropositive: 43.7% (95% CI:[39.5%–47.9%]) in those whose geographic origin was Metropolitan France and 84.1% in those with other origins (95% CI:[79.2%–88.3%]). Determinants associated with CMV seropositivity in a multivariate logistic regression model were: (i) geographic origin (p<0.001(compared with Metropolitan France, geographic origins of Africa adjusted odds ratio (aOR) 21.2, 95% CI:[9.7–46.5], French overseas departments and territories and other origin, aOR 7.5, 95% CI:[3.9–14.6], and Europe or Asia, aOR 2.2, 95% CI: [1.3–3.7]); and (ii) gravidity (p = 0.019), (compared with gravidity = 1, if gravidity≥3, aOR = 1.5, 95% CI: [1.1–2.2]; if gravidity = 2, aOR = 1.0, 95% CI: [0.7–1.4]). Work characteristics and socioeconomic status were not independently associated with CMV seropositivity. Conclusions In this cohort of pregnant women, a geographic origin of Metropolitan France and a low gravidity were predictive factors for CMV low seropositivity. Such women are therefore the likely target population for prevention of CMV infection during pregnancy in France. PMID:24587077

The major branch of the Seine river from the confluence with the Marne river to the entrance of the estuary is deeply affected by the release of wastewater from the huge Paris agglomeration. In the first years of 2000, the largest part of the effluents were still discharged at the Seine-Aval (Achères) treatment plant with only a standard, low residence time, activated sludge treatment, thus releasing a high ammonium load. NH4 concentration as high as 7 mgN/l were frequently observed downstream from Paris agglomeration. Cébron et al. (2003, 2005) and Garnier et al. 2007 described in details how this massive reduced nitrogen concentrations triggered the growth of nitrifying bacteria, already present in the upstream Seine and Marne rivers, but also brought in large amount by the effluents of the wastewater treatment plant themselves. The decrease of ammonium concentration was slow, however, and was only completed 200 km downstream, in the upper estuarine area, where it causes a severe oxygen deficiency. Since 2007, important changes occurred in the treatment of nitrogen in the Parisian wastewater purification plants. In 2007, the Seine-Aval plant treated up to 90% of the ammonium contained in wastewater through nitrification, and 30% of the total supply of nitrates is treated by denitrification. These modifications have of course favorably affected the water quality of the Seine river: ammonium concentrations are reduced by a factor of 5 and the area of oxygen depletion in the upstream estuary is no more observed. However, nitrites, still released in the effluents, are a matter of concern for the water quality of the Seine downstream from Paris. Using measurements of potential microbial activities carried out with the same experimental protocol for the 2000-2003 and 2012-2013 periods, we here examine and model the dynamics of ammonium oxidizing and nitrite oxidizing microbial populations before and after the implementation of nitrification treatment of Paris

Building energy efficiency is an important strategy for reducing greenhouse gas emissions globally. In fact, 55 countries have included building energy efficiency in their Nationally Determined Contributions (NDCs) under the Paris Agreement. This research uses building energy code implementation in six cities across different continents as case studies to assess what it may take for countries to implement the ambitions of their energy efficiency goals. Specifically, we look at the cases of Bogota, Colombia; Da Nang, Vietnam; Eskisehir, Turkey; Mexico City, Mexico; Rajkot, India; and Tshwane, South Africa, all of which are “deep dive” cities under the Sustainable Energy formore » All's Building Efficiency Accelerator. The research focuses on understanding the baseline with existing gaps in implementation and coordination. The methodology used a combination of surveys on code status and interviews with stakeholders at the local and national level, as well as review of published documents. We looked at code development, implementation, and evaluation. The cities are all working to improve implementation, however, the challenges they currently face include gaps in resources, capacity, tools, and institutions to check for compliance. Better coordination between national and local governments could help improve implementation, but that coordination is not yet well established. For example, all six of the cities reported that there was little to no involvement of local stakeholders in development of the national code; only one city reported that it had access to national funding to support code implementation. More robust coordination could better link cities with capacity building and funding for compliance, and ensure that the code reflects local priorities. By understanding gaps in implementation, it can also help in designing more targeted interventions to scale up energy savings.« less

Accurate, consistent reporting of changing forest area, stratified by forest type, is required for all countries under their commitments to the Paris Agreement (UNFCCC 2015 Adoption of the Paris Agreement (Paris: UNFCCC)). Such change reporting may directly impact on payments through comparisons to national Reference (Emissions) Levels under the Reducing Emissions from Deforestation and forest Degradation (REDD+) framework. The emergence of global, satellite-based forest monitoring systems, including Global Forest Watch (GFW) and FORMA, have great potential in aiding this endeavour. However, the accuracy of these systems has been questioned and their uncertainties are poorly constrained, both in terms of the spatial extent of forest loss and timing of change. Here, using annual time series of 5 m optical imagery at two sites in the Brazilian Amazon, we demonstrate that GFW more accurately detects forest loss than the coarser-resolution FORMA or Brazil’s national-level PRODES product, though all underestimate the rate of loss. We conclude GFW provides robust indicators of forest loss, at least for larger-scale forest change, but under-predicts losses driven by small-scale disturbances (< 2 ha), even though these are much larger than its minimum mapping unit (0.09 ha).

Despite the widespread offer of free HIV testing in France, the proportion of people who have never been tested remains high. The objective of this study was to identify, in men and women separately, the various factors independently associated with no lifetime HIV testing. We used multilevel logistic regression models on data from the SIRS cohort, which included 3006 French-speaking adults as a representative sample of the adult population in the Paris metropolitan area in 2010. The lifetime absence of any HIV testing was studied in relation to individual demographic and socioeconomic factors, psychosocial characteristics, sexual biographies, HIV prevention behaviors, attitudes towards people living with HIV/AIDS (PLWHA), and certain neighborhood characteristics. In 2010, in the Paris area, men were less likely to have been tested for HIV at least once during their lifetime than women. In multivariate analysis, in both sexes, never having been tested was significantly associated with an age younger or older than the middle-age group (30-44 years), a low education level, a low self-perception of HIV risk, not knowing any PLWHA, a low lifetime number of couple relationships, and the absence of any history of STIs. In women, other associated factors were not having a child < 20 years of age, not having additional health insurance, having had no or only one sexual partner in the previous 5 years, living in a cohabiting couple or having no relationship at the time of the survey, and a feeling of belonging to a community. Men with specific health insurance for low-income individuals were less likely to have never been tested, and those with a high stigma score towards PLWHA were more likely to be never-testers. Our study also found neighborhood differences in the likelihood of men never having been tested, which was, at least partially, explained by the neighborhood proportion of immigrants. In contrast, in women, no contextual variable was significantly associated with

Between 1991 and 1993, 18 fogwater samples, 31 rainwater samples and 17 atmosphere (gas and particles) samples were analysed for 13 pesticides (pp'DDT,pp'DDD,pp'DDE, aldrin, dieldrin, lindane, hexachlorobenzene, fenpropathrin, mecoprop, methyl-parathion, atrazine, isoproturon and aldicarb). The samples were collected in a rural area where some of the compounds are in use (experimental INRA farm, "Institut National de la Recherche Agronomique" in Colmar, Eastern France, 80,000 inhabitants). This paper briefly presents the analytical methodology used and, in detail, the contamination level of the different atmospheric phases. The contamination levels are roughly constant throughout the year in all the atmospheric phases and the most abundant pesticides are those commonly used on the experimental INRA farm and other surrounding farms. Nevertheless, some pesticides not used since the 1970s such as 1,1-Bis(4-chlorophenyl)-2,2,2-trichloroethane (pp'DDT) and 2,2-Bis(4-chlorophenyl)-1,1-dichloroethane (pp 'DDD) are also detected in the atmosphere of Colmar. A small increase in the pesticide concentrations in the atmosphere (gas and particles) was observed during treatments.

Except for comparing the implementation costs of the Paris Agreement with potential health benefits at the national levels, previous studies have not explored the health impacts of the nationally determined contributions (NDCs) by countries and in regional details. In this Lancet Countdown study, we aimed to estimate and monetise the health benefits of China's NDCs in the electric power generation sector, and then compare them with the implementation costs, both at the national and regional levels. In this modelling study, we linked the Multi-regional model for Energy Supply system and their Environmental ImpaCts, the Multi-resolution Emission Inventory for China model, the offline-coupled Weather Research and Forecasting model, the Community Multiscale Air Quality model, and the Integrated Health Impact Assessment model with a time scope from 2010 to 2050. We calculated the PM 2·5 concentrations and compared the health impacts and implementation costs between two scenarios that reflect CO 2 and air pollutant emissions-the reference (REF) scenario (no climate policy) and the NDC scenario (100% realisation of NDC targets: CO 2 emission intensity needs to be about 40% below 2010 emissions by 2030 [roughly 35% below 2030 emissions in REF], and about 90% below 2010 emissions by 2050 [roughly 96% below 2050 emissions in REF]). Under a comparatively optimistic health benefits valuation condition, at the national level, 18-62% of implementation costs could be covered by the health benefits in 2030. In 2050, the overall health benefits would substantially increase to 3-9 times of the implementation costs. However, northwest China would require the highest implementation costs and will also have more premature deaths because of a more carbon-intensive energy structure than business as usual. By 2030, people in northwest China (especially in Gansu, Shaanxi, and Xinjiang provinces) would need to bear worse air quality, and 10 083 (95% CI 3419-16 138) more premature
