    The purpose of this study was to validate the agricultural lower limb assessment (ALLA) ergonomic checklist, which was developed for various agricultural tasks in Korea. One hundred and ninety-six working postures were selected from the real agricultural tasks to verify ALLA, a lower limb body posture assessment tool, and then evaluated by 16 ergonomic experts. Hit rate, quadratic weighted κ, one-way analysis of variance and t-test analyses were applied to compare ALLA with other assessment tools. ALLA analysis had a superior hit rate with ergonomic expert assessment compared with other assessment tools. Quadratic weighted κ analysis also showed that ALLA provided superior estimates of risk levels for farm working postures. ALLA would be an appropriate assessment tool to estimate risk factors for various lower limb body postures which frequently occur in agricultural tasks in Korea. ALLA is a simple and accurate risk assessment tool that could be usefully applied to identify and mitigate risk factors and work-related musculoskeletal disorders in agricultural tasks, and also to evaluate the effects of control and intervention for working conditions.

    Numerous archaeological sites dating to the greek-roman period have been found in the underground of the city of Catania (eastern Sicily, Italy). Their presence is a testimony of the several settlements that have followed in this area over time. In this work we have conducted electromagnetic surveys, consisting of ten georadar profiles, inside the church of “S. Agata alla Badia”, damaged during the earthquake occurred in eastern Sicily on 13 December 1990. The aim was to investigate the area where the church is located to obtain information useful for its structural recovery. Mechanical drillings were also carried out to reconstruct the local stratigraphy, which could be complicated by the presence of underground cavities and artefacts, as evidenced by recent excavations beneath the Catania Cathedral, in the nearby Piazza Duomo. From the interpretation of the GPR data, the presence of ancient masonry structures underlying the recent foundations was highlighted. In addition, the GPR survey allowed us to identify and locate reflective horizons in the subsurface, probably due to the presence of materials with different state of aggregation and/or to buried structures.

  3. Quantification of character-impacting compounds in Ocimum basilicum and 'Pesto alla Genovese' with selected ion flow tube mass spectrometry.

    Basil (Ocimum basilicum) is an important flavourant plant which constitutes the major ingredient of the pasta sauce 'Pesto alla Genovese'. The characteristic smell of basil stems mainly from a handful of terpenoids (methyl cinnamate, eucalyptol, linalool and estragole), the concentration of which varies according to basil cultivars. The simple and rapid analysis of the terpenoid constituents of basil would be useful as a means to optimise harvesting times and to act as a quality control process for basil-containing foodstuffs. Classical analytical techniques such as gas chromatography/mass spectrometry (GC/MS) are, however, slow, technically demanding and therefore less suitable for routine analysis. A new chemical ionisation technique which allows real-time quantification of traces gases, Selected Ion Flow Tube Mass Spectrometry (SIFT-MS), was therefore utilised to determine its usefulness for the assay of terpenoid concentrations in basil and pesto sauce headspace. Trace gas analysis was performed using the NO(+) precursor ion which minimised interference from other compounds. Character-impacting compound concentration was measured in basil headspace with good reproducibility and statistically significant differences were observed between cultivars. Quantification of linalool in pesto sauce headspace proved more difficult due to the presence of interfering compounds. This was resolved by careful selection of reaction product ions which allowed us to detect differences between various commercial brands of pesto. We conclude that SIFT-MS may be a valid tool for the fast and reproducible analysis of flavourant terpenoids in basil and basil-derived foodstuffs. Copyright © 2011 John Wiley & Sons, Ltd.

    In 2007 the Italian Ministry of Health/CCM promoted and funded the project "System of surveys of behavioral risks in ages 6-17", coordinated by the National Institute of Health. One of the aims of the project is the definition and implementation of a data collection system on the weight of primary school children, their eating habits, physical activity and school initiatives favoring the healthy growth of children, called "OKkio alla SALUTE". In 2008 the first survey of OKkio was conducted in 18 Italian regions. 45,590 third grade school children in 2610 classes participated. Information was collected from 2461 schools. The responses of the head teachers showed that 64% of the schools have a canteen, used by 70% of children. Only 12% of schools include the provision of a balanced mid-morning snack. Frequently there are educational activities related to physical activity and healthy eating that, in some cases, also involve the families of the children. 29% of the schools cannot guarantee two hours of physical activity as suggested by the school curriculum because of the lack or inadequacy of the gym or the structure of the timetables. The information gathered through the cooperation of school administrators, teachers and health workers, has helped to describe the major health educational activities of the school, that is confirmed to be the ideal venue for promoting healthy lifestyles in young people.

  3. Aluminum oxide formation at Al/La(1-x)Sr(x)MnO3 interface: a computational study for resistance random access memory applications.

    PubMed

    Lee, Nodo; Lansac, Yves; Jang, Yun Hee

    2011-01-01

    Resistance random access memory (ReRAM) is emerging as a next-generation nonvolatile memory. One of the most promising materials for the ReRAM application is a composite of a reactive metal [such as aluminum (Al)] and a mixed-valance manganite [such as La(1-x)Ca(x)MnO3 (LCMO) and La(1-x)Sr(x)MnO3 (LSMO)]. One of the current hypotheses regarding the origin of the resistive switching of such systems is a voltage-controlled reversible formation of a high-resistance aluminum oxide (AlO(x)) layer at the Al/LC(S)MO interface through oxygen migration from LC(S)MO. To validate this hypothesis, quantum mechanics (density functional theory) calculations were carried out on an atomistic model of the resistive-switching phenomena at the Al/LSMO interface (the composite systems of Al/LSMO and AlO(x)/LSMO) as well as on the component materials such as Al, AlO(x), LaMnO3, LaMnO(3-delta), La(1-x)Sr(x)MnO3, and La(1-x)Sr(x)MnO(3-delta). The changes in the structure, energy, and electronic structure of these systems during the oxygen vacancy formation in LSMO, the oxygen migration through the Al/LSMO interface, and the AlO(x) formation were investigated.

    Half of patients with acute heart failure syndromes (AHFS) have preserved left ventricular ejection fraction (PLVEF). In this setting, the role of minor myocardial damage (MMD), as identified by cardiac troponin T (cTnT), remains to be established. To evaluate the prevalence and long-term prognostic significance of cTnT elevations in patients with AHFS and PLVEF. This retrospective, multicenter, collaborative study included 500 patients hospitalized for AHFS with PLVEF (ejection fraction ≥40%) between October 2000 and December 2006. Blood samples were collected within 12 hours after admission and were assayed for cTnT. MMD was defined as a cTnT value of ≥0.020 ng/mL. Mean age was 73 ± 12 years, 47% were female, 38% had an ischemic etiology, and New York Heart Association (NYHA) class was 2.2 ± 0.7. Mean cTnT value was 0.149 ± 0.484 ng/mL, and cTnT was directly correlated with serum creatinine (Spearman's Rho = 0.35, P < .001) and NYHA class (0.25, P < .001). MMD was diagnosed in 220 patients (44%). Patients with MMD showed lower left ventricular ejection fraction (P < .05), higher serum creatinine (P < .001), higher prevalence of ischemic etiology and diabetes mellitus, a worse NYHA class (P < .001), and higher natriuretic peptide levels (P < .001) as compared with patients without MMD. At 6-month follow-up, overall event-free survival was 55% and 75% in patients with and without MMD (P < .001), respectively. On multivariate Cox regression analysis, only NYHA class (HR = 1.50; P = .002) and MMD (HR = 1.81; P = .001) were identified as predictors of events. Increased cTnT levels were detected in approximately 50% of patients with AHFS with preserved systolic function, and were found to correlate with clinical measures of disease severity. The presence of MMD was associated with a worse long-term outcome, lending support to cTnT-based risk stratification in the setting of AHFS. Copyright © 2012 Elsevier Inc. All rights reserved.

    The great meridian line in the Basilica of Santa Maria degli Angeli in Rome was built in 1701/1702 with the scope to measure the Obliquity of the Earth's orbit in the following eight centuries, upon the will of pope Clement XI. During the winter solstice of 1701 the first measurements of the obliquity have been realized by Francesco Bianchini, the astronomer who designed the meridian line, upgrading the similar instrument realized by Giandomenico Cassini in San Petronio, Bononia. In this paper the accuracy of the data observed by Francesco Bianchini is discussed and compared with up-to-date ephemerides. The modern situation of this historical instrument is also presented.

We find that there are certain restrictions when the isolated {open_quotes}tetrahedral{close_quotes} gas evolves towards equilibrium. In addition to the well-known increase in entropy, the quantity called disequilibrium decreases monotonically with time.

  17. Statistical manifestation of quantum correlations via disequilibrium

    NASA Astrophysics Data System (ADS)

    Pennini, F.; Plastino, A.

    2017-12-01

    The statistical notion of disequilibrium (D) was introduced by López-Ruiz, Mancini, and Calbet (LMC) (1995) [1] more than 20 years ago. D measures the amount of ;correlational structure; of a system. We wish to use D to analyze one of the simplest types of quantum correlations, those present in gaseous systems due to symmetry considerations. To this end we extend the LMC formalism to the grand canonical environment and show that D displays distinctive behaviors for simple gases, that allow for interesting insights into their structural properties.

    The position-momentum Shannon and Renyi uncertainty products of general quantum systems are shown to be bounded not only from below (through the known uncertainty relations), but also from above in terms of the Heisenberg-Kennard product . Moreover, the Cramer-Rao, Fisher-Shannon, and Lopez-Ruiz, Mancini, and Calbet shape measures of complexity (whose lower bounds have been recently found) are also bounded from above. The improvement of these bounds for systems subject to spherically symmetric potentials is also explicitly given. Finally, applications to hydrogenic and oscillator-like systems are done.

    With the financial market globalization, foreign investments became vital for the economies, mainly in emerging countries. In the last decades, Brazilian exchange rates appeared as a good indicator to measure either investors' confidence or risk aversion. Here, some events of global or national financial crisis are analyzed, trying to understand how they influenced the "dollar-real" rate evolution. The theoretical tool to be used is the López-Mancini-Calbet (LMC) complexity measure that, applied to real exchange rate data, has shown good fitness between critical events and measured patterns.

  2. Robustness of the Gaussian interferometric power in two optomechanical systems

    Es-Sahely, Y.; El Qars, J.; Daoud, M.; Ahl Laamara, R.

    In two optomechanical systems, we study the robustness of the Gaussian interferometric power (GIP) against thermal noises. We use the Mancini et al. criterion to distinguish between entangled and separable states. Also, we employ the GIP to capture the nonclassical feature of the two studied systems beyond entanglement. We evaluate explicitly these two indicators of nonclassicality as functions of parameters characterizing the environment and the optomechanical systems (temperature, coupling, etc). We show that the inseparable quantum correlations decay strongly enough than those existing in separable states under thermal noises. On the other hand, when the separability criterion failed, the GIP remains almost constant and nonzero in the two systems even for high temperatures. This show that the GIP is an appropriate measure to capture the quantumness of correlations especially for systems coupled to environment strongly affected by thermal noises.

    A two-parameter family of complexity measures C-tilde{sup ({alpha},{beta})} based on the Renyi entropies is introduced and characterized by a detailed study of its mathematical properties. This family is the generalization of a continuous version of the Lopez-Ruiz-Mancini-Calbet complexity, which is recovered for {alpha}=1 and {beta}=2. These complexity measures are obtained by multiplying two quantities bringing global information on the probability distribution defining the system. When one of the parameters, {alpha} or {beta}, goes to infinity, one of the global factors becomes a local factor. For this special case, the complexity is calculated on different quantum systems: H-atom, harmonic oscillator, andmore » square well.« less

    The internal disorder of hydrogenic Rydberg atoms as contained in their position and momentum probability densities is examined by means of the following information-theoretic spreading quantities: the radial and logarithmic expectation values, the Shannon entropy, and the Fisher information. As well, the complexity measures of Cramer-Rao, Fisher-Shannon, and Lopez Ruiz-Mancini-Calvet types are investigated in both reciprocal spaces. The leading term of these quantities is rigorously calculated by use of the asymptotic properties of the concomitant entropic functionals of the Laguerre and Gegenbauer orthogonal polynomials which control the wavefunctions of the Rydberg states in both position and momentum spaces. The associatedmore » generalized Heisenberg-like, logarithmic and entropic uncertainty relations are also given. Finally, application to linear (l= 0), circular (l=n- 1), and quasicircular (l=n- 2) states is explicitly done.« less

    Capital flows are responsible for a strong influence on the foreign exchange rates and stock prices macroeconomic parameters. In volatile economies, capital flows can change due to several types of social, political and economic events, provoking oscillations on these parameters, which are recognized as economic crises. This work aims to investigate how these two macroeconomic variables are related with crisis events by using the traditional complex measures due to Lopez-Mancini-Calbet (LMC) and to Shiner-Davison-Landsberg (SDL), that can be applied to any temporal series. Here, Ibovespa (Bovespa Stock Exchange main Index) and the “dollar-real” parity are the background for calculating the LMC and SDL complexity measures. By analyzing the temporal evolution of these measures, it is shown that they might be related to important events that occurred in the Brazilian economy. PMID:28301506

    Following the stellar career of papal physician Giulio Mancini, the article brings into focus learned doctors’ uses of, and relationships with, manu- scripts. Manuscripts were the main outcome of their practice — as letters of consultation to patients and colleagues, as consilia of various kinds, including for use in courts of law, and also in the form of key professional tools such as casebooks. Clues found in Mancini’s rich paper-trail shed light on material aspects of his professional writing and on the role that circulating knowledge in manuscript had in creating and sustaining medical networks. The article also argues that even in a domain as shaped by print as early modern medicine, physicians’ use of this medium should not be taken for granted; especially in courtly settings, scribal, as opposed to print, publishing provided them with an effective means of building the social relationships on which their careers depended.

    The concept of complexity has been widely discussed in the last forty years, with a lot of thinking contributions coming from all areas of the human knowledge, including Philosophy, Linguistics, History, Biology, Physics, Chemistry and many others, with mathematicians trying to give a rigorous view of it. In this sense, thermodynamics meets information theory and, by using the entropy definition, López-Ruiz, Mancini and Calbet proposed a definition for complexity that is referred as LMC measure. Shiner, Davison and Landsberg, by slightly changing the LMC definition, proposed the SDL measure and the both, LMC and SDL, are satisfactory to measure complexity for a lot of problems. Here, SDL and LMC measures are applied to the case of a binomial probability distribution, trying to clarify how the length of the data set implies complexity and how the success probability of the repeated trials determines how complex the whole set is.

    The character Mr. Palomar, the alter-ego of the Italian author Italo Calvino, appeared for the first time in 1975 on the pages of the ``Il Corriere della Sera'', and then more or less regularly till its debut as a book in 1983. Through illuminating thoughts and reflections based on observations, for instance, of sea waves, Mr. Palomar discovers that they induce a peaceful and inspirational state of mind that prevents coronary and mental illnesses, and also holds the key to capturing the complexity of the world reducing it into its most elementary mechanisms. In this contribution I will survey some of Mr. Palomar's thoughts while he observes the sky and speculate on others that he might have explored if he shared our contemporary knowledge of the cosmos. I will also discuss the thoughts of other authors on how, cosmological thinking affects the human condition.

    The paper presents the optimization of a methodology for automatic clustering based on Artificial Neural Networks to detect the presence of defects in rolling bearings. The research activity was developed in co-operation with an Italian company which is expert in the production of water pumps for automotive use (Industrie Saleri Italo). The final goal of the work is to develop a system for the automatic control of the pumps, at the end of the production line. In this viewpoint, we are gradually considering the main elements of the water pump, which can cause malfunctioning. The first elements we have considered are the rolling bearing, a very critic component for the system. The experimental activity is based on the vibration measuring of rolling bearings opportunely damaged; vibration signals are in the second phase elaborated; the third and last phase is an automatic clustering. Different signal elaboration techniques are compared to optimize the methodology.

    Supplement users have better vitamin D status, and parenting is key to promoting a child's healthy behaviours. We examined the association of parental encouragement of and caring about healthy lifestyles with children's use of vitamin D supplements and multivitamins. A provincially representative sample of grade 5 students (n = 2686; 10-11 years) and their parents across the province of Alberta, Canada, was surveyed in 2014. Students were asked about use of multivitamins and/or vitamin D supplements. Parents were asked whether they cared about and encouraged healthy lifestyles. Mixed effect multiple logistic regression identified the association of parental responses with children's use of supplements; 29% and 54% of children took vitamin D supplements and multivitamins, respectively. They were more likely to take vitamin D supplements if their parents cared 'very much' vs. 'not at all/a little bit' about eating healthy foods (OR = 1.43; 95% CI = 1.08, 1.89), cared 'quite a lot' (OR = 1.55; 95% CI = 1.17, 2.04) and 'very much' (OR = 1.67; 95% CI = 1.26, 2.21) vs. 'not at all/a little bit' about physical activity, and encouraged 'very much' vs. 'not at all/a little bit' their children to eat healthy foods (OR = 1.51; 95% CI = 1.05, 2.17). Children whose parents personally cared for eating healthy foods were more likely to take multivitamins ('quite a lot' and 'very much' compared to 'not at all/a little bit' (OR = 1.60; 95% CI = 1.13, 2.28 and OR = 1.46; 95% CI = 1.04, 2.06, respectively). Education and parental encouragement of healthy lifestyles should be part of the public health initiatives to promote supplementation of vitamin D among children.

    Time-resolved spectral data from recent ICF implosion experiments of plastic microballoons containing deuterium fuel doped with argon is proving quite useful in checking the corresponding 1D and 2D simulation results from the multi-dimensional hydrocode RAGE [1]. Comparisons with experimental density and temperature determined by fitting theoretical argon line shapes generated by MERL [2] to experimental data show that the simulated density and temperature in the fuel are too large unless some seed for mixing is incorporated. We use a nonuniform drive as a seed for mix. The need for mix is further supported through simulations using the 1D Lagrangian code HYADES (no mix) that give neutron yields an order of magnitude larger than that seen in experiment.

    Insulin-dependent Diabetes (IDDM) is a major endocrine abnormality in children and the greatest morbi-mortality problems for diabetic patients are those related to cardiovascular complications (macro-microangiopaties), where kept hyperlipidemia and hyperglucemia play a fundamental patogenic role. The programs for optimization of home autocontrol have reduced frequent metabolic derangements. The aim of this study was to analyze the metabolic control state and its relationships with plasma lipids and atherogenic ratios in diabetic patients that were submitted to a program for optimization of home autocontrol of this illness. Blood samples were taken fom 49 IDDM, aged 10.53 +/- 0.51 (+/- SEM) years old, with a mean evolution period of 4.34 +/- 0.38 years, at the begining of the program (Stage I) and 6 months later (Stage II). Biochemical Analysis: Total Cholesterol (TC), cholesterol joined to high density lipoprotein (HDLc), Triglycerides (TG) and Phospholipids (Ph) were measured by microspectrphotometric methods. Cholesterol joined to very low and low density lipoproteins (VLDLc and LDLc, respectively) were calculated by Friedwald's formula. Apoproteins A and B (Apo A and Apo B) were measured using Mancini's method, Glycemia levels (Gly) by peroxidase's method, Glycosilated Serum Protein (GSP) by colormetric's method and Glycosilated haemoglobine (HbA1c) by chromatographic separation using cationic interchange microcolumns. 65% of the patients showed a significant decrease in plasma levels of Gly, GSP and HbA1c percentage between Stages I and II (Favourable Metabolic Control).(ABSTRACT TRUNCATED AT 250 WORDS)

  4. Visual detail about the body modulates tactile localisation biases.

    PubMed

    Margolis, Aaron N; Longo, Matthew R

    2015-02-01

    The localisation of tactile stimuli requires the integration of visual and somatosensory inputs within an internal representation of the body surface and is prone to consistent bias. Joints may play a role in segmenting such internal body representations, and may therefore influence tactile localisation biases, although the nature of this influence remains unclear. Here, we investigate the relationship between conceptual knowledge of joint locations and tactile localisation biases on the hand. In one task, participants localised tactile stimuli applied to the dorsum of their hand. A distal localisation bias was observed in all participants, consistent with previous results. We also manipulated the availability of visual information during this task, to determine whether the absence of this information could account for the distal bias observed here and by Mancini et al. (Neuropsychologia 49:1194-1201, 2011). The observed distal bias increased in magnitude when visual information was restricted, without a corresponding decrease in precision. In a separate task, the same participants indicated, from memory, knuckle locations on a silhouette image of their hand. Analogous distal biases were also seen in the knuckle localisation task. The accuracy of conceptual joint knowledge was not correlated with tactile localisation bias magnitude, although a similarity in observed bias direction suggests that both tasks may rely on a common, higher-order body representation. These results also suggest that distortions of conceptual body representation may be more common in healthy individuals than previously thought.

    This study was realiszed in Côte d'Ivoire at the children from 5 to 15 years old. The purpose of this study was to determine the alteration of immunity, inflammatory and nutritional proteins at 142 children (30 minor and 12 moderated malnutrition). The nutritional state or the state of malnutrition was to appreciate by Weight/height ratio which is the most usued by far. Immunity, inflammatory and nutritional proteins were measured by radical immunodiffusion according to Mancini. The results of this study showed that the Albumin was lowered (p<0.01) during the moderate and minor malnutrition in comparison to the children.On the other hand, it was observed an increased of CRP in both forms of malnutrition (p<0.05).Also, the index prognostic nutritional and inflammatory who, allows to appreciate simultaneously the inflammatory and nutritional state (PINI) was increased in the malnutrition moderated with regard to the minor malnutrition and to the children (p<0.05).Besides, immunity proteins remain unchanged in both forms of malnutrition in comparison to the healthy children (p<0.05). Finally, this study shows that the moderate and malnutrition are associated with an inflammatory process and of protein consumption notably the Albumin .These observations suggest that determination of the nutritional status requires the use of the clinical method coupled with the biological examinations.

    Agammaglobulinemia with absence of circulating B lymphocytes is a rare genetically transmitted immunodeficiency that appears in early childhood and affect mainly boys. The clinical manifestations of the disease are rather heterogeneous. Nine patients (7 boys and 2 girls) were diagnosed as suffering from agammaglobulinemia with absence of circulating B lymphocytes, over a period of 6 years. Quantitation of immunoglobulins and search for circulating B lymphocytes were respectively performed by the Mancini method and immunofluorescence using T specific (anti-CD3, anti-CD4 and anti-CD8) and B (anti-CD19) monoclonal antibody. The disease started to manifest clinically at the mean age of 8.7 months (4-16 months). The mean age at diagnosis is 4 years (1-11 years). The clinical manifestations were essentially recurrent infections of the lung and the gastrointestinal tract. However, bacterial meningitidis was observed in 3 patients. Severe complications such as an echovirus 27 meningoencephalitis and a chronic active hepatitis (1 patient) and a pericarditis (1 patient) were observed. All of our patients lacked circulating B lymphocytes and had low or null immunoglobulin levels. Five patients were treated by intravenous immunoglobulin (Ig) and 3 were treated by intramuscular immunoglobulin with a residual IgG level respectively of 5.5 g/l and 3.3 g/l. Recurrent infections are the principal manifestation of the agammaglobulinemia, early Ig treatment is the only therapy allowing improved.

    Summary This article is based on analysis of 4 couple’s personal and public documents, in order to integrate personal choices, values and ideas with cultural representations and social attitudes. Moreover, being based on Italian sources from the nineteenth century, the study offers an historical insight on the Italian nation-building process and its political and social foundations. This study is based on archival and printed primary sources from: Gianna Maffei and Ercole Trotti Mosti (Museo Centrale del Risorgimento – Roma – MCRR); Augusto Pierantoni and Grazia Mancini (Museo Centrale del Risorgimento – Roma); Luigi Majno and Ersilia Bronzini (Archivio Unione Femminile Nazionale – Milano); Angiolo Orvieto and Laura Cantoni (Archivio Contemporaneo Bonsanti del Gabinetto Vieuesseux – Firenze – ACGV). This study reflects on love as a political and moral issue, by linking the personal sphere of subjectivity to the public dimension of the political community. An extensive understanding of the role played by the perception and the expression of sentiments can be considered as the central issue of this analysis. PMID:22037756

    At the centre of this article are two physicians active in Rome between 1600 and 1630 who combined medical practice with broader involvement in the dynamic cultural, economic and political scene of the centre of the Catholic world. The city's distinctive and very influential social landscape magnified issues of career-building and allows us to recapture physicians’ different strategies of self-fashioning at a time of major social and religious reorganization. At one level, reconstructing Johannes Faber and Giulio Mancini's medical education, arrival in Rome and overlapping but different career trajectories contributes to research on physicians’ identity in early modern Italian states. Most remarkable are their access to different segments of Roman society, including a dynamic art market, and their diplomatic and political role, claimed as well as real. But following these physicians from hospitals to courts, including that of the Pope, and from tribunals to the university and analysing the wide range of their writing – from medico-legal consilia to political essays and reports of anatomical investigations – also enriches our view of medical practice, which included, but went beyond, the bedside. Furthermore, their activities demand that we reassess the complex place of anatomical investigations in a courtly society, and start recovering the fundamental role played by hospitals – those quintessential Catholic institutions – as sites of routine dissections for both medical teaching and research.

    2009-01-01

    The publication combines data on Paleozoic and Mesozoic stratigraphy and petroleum geology of the Illinois basin, U.S.A., in order to facilitate visualizing the stratigraphy on a regional scale and visualizing stratigraphic relations within the basin. Data are presented in eight schematic chronostratigraphic sections arranged approximately from north to south, with time denoted in equal increments along the sections, in addition to the areal extent of this structural basin. The stratigraphic data are modified from Hass (1956), Conant and Swanson (1961), Wilman and others (1975), American Association of Petroleum Geologists (1984, 1986), Olive and McDowell (1986), Shaver and others (1986), Thompson (1986), Mancini and others (1996), and Harrison and Litwin (1997). The time scale is taken from Gradstein and others (2004). Additional stratigraphic nomenclature is from Harland and others (1990), Babcock and others (2007), and Bergstrom and others (2008). Stratigraphic sequences as defined by Sloss (1963, 1988) and Wheeler (1963) also are included, as well as the locations of major petroleum source rocks and major petroleum plays. The stratigraphic units shown are colored according to predominant lithology, in order to emphasize general lithologic patterns and to provide a broad overview of the Illinois basin. For the purpose of comparison, three columns on the right show schematic depictions of stratigraphy and interpreted events in the Illinois basin and in the adjacent Michigan and Appalachian basins.

    Costruito per chiara volontà del papa 70 anni dopo il caso Galileo, lo Gnomone Clementino è un grande telescopio solare che non fa uso di lenti a 92 anni dall’invenzione del cannocchiale. Queste due caratteristiche basterebbero da sole a giustificare l’interesse verso questo strumento. L’astronomia meridiana è alla base dell’astrometria e dell’astrofisica moderna. Lo Gnomone Clementino sta oggi all’astronomia, come il veliero “Amerigo Vespucci” sta alla Marina Italiana.

    On the Waterfront Italo Falcomatà of Reggio Calabria you can admire the most extensive tract of the walls of the Hellenistic period of ancient city of Rhegion. The so-called Greek Walls are one of the most significant and visible traces of the past linked to the culture of Ancient Greece in the site of Reggio Calabria territory. Over the years this stretch of wall has always been a part, to the reconstruction of Reggio after the earthquake of 1783, the outer walls at all times, restored countless times, to cope with the degradation of the time and the adjustments to the technical increasingly innovative and sophisticated siege. They were the subject of several studies on history, for the study of the construction techniques and the maintenance and restoration of the same. This note describes the methodology for the implementation of a three-dimensional model of the Greek Walls conducted by the Geomatics Laboratory, belonging to DICEAM Department of University “Mediterranea” of Reggio Calabria. 3D modeling we made is based on imaging techniques, such as Digital Photogrammetry and Computer Vision, by using a drone. The acquired digital images were then processed using commercial software Agisoft PhotoScan. The results denote the goodness of the technique used in the field of cultural heritage, attractive alternative to more expensive and demanding techniques such as laser scanning.

    Alzheimer's disease (AD) is the most common cause of dementia. Over the last few years, a considerable effort has been devoted to exploring new biomarkers. Nevertheless, a better understanding of brain dynamics is still required to optimize therapeutic strategies. In this regard, the characterization of mild cognitive impairment (MCI) is crucial, due to the high conversion rate from MCI to AD. However, only a few studies have focused on the analysis of magnetoencephalographic (MEG) rhythms to characterize AD and MCI. In this study, we assess the ability of several parameters derived from information theory to describe spontaneous MEG activity from 36 AD patients, 18 MCI subjects and 26 controls. Three entropies (Shannon, Tsallis and Rényi entropies), one disequilibrium measure (based on Euclidean distance ED) and three statistical complexities (based on Lopez Ruiz-Mancini-Calbet complexity LMC) were used to estimate the irregularity and statistical complexity of MEG activity. Statistically significant differences between AD patients and controls were obtained with all parameters (p < 0.01). In addition, statistically significant differences between MCI subjects and controls were achieved by ED and LMC (p < 0.05). In order to assess the diagnostic ability of the parameters, a linear discriminant analysis with a leave-one-out cross-validation procedure was applied. The accuracies reached 83.9% and 65.9% to discriminate AD and MCI subjects from controls, respectively. Our findings suggest that MCI subjects exhibit an intermediate pattern of abnormalities between normal aging and AD. Furthermore, the proposed parameters provide a new description of brain dynamics in AD and MCI.

    Serum levels of the immunoglobulins: IgG, IgA and IgM were determined by the single radial immunodiffusion technique of Mancini in a total of 122 apparently healthy subjects consisting of 43 children (20 males; 23 females) aged 5-12 years and 79 adults (39 males; 40 females) aged 18-65 years resident in Port Harcourt, southeastern Nigeria. The effects of age and sex on the serum levels of the various immunoglobulin types were also determined. The mean values and ranges for the various immunoglobulin types are presented for both children and adults. Although, female children were found to have significantly lower mean values of IgA compared to male children (p<0.05), there were no significant differences in the mean values of both IgG and IgM between male and female children involved in the present study (p>0.05). However, female adults had significantly higher mean values of IgG and significantly lower mean values of IgA compared to male adults (p<0.05); suggesting a significant gender difference in the value of both IgG and IgA amongst adult subjects. No significant differences were observed in the mean values of any of the various types of immunoglobulin between adults and children. The present study reports mean values of the various types of immunoglobulin in apparently healthy children and adults resident in Port Harcourt, southeastern Nigeria. Significant gender differences were observed for some of the immunoglobulin types only amongst adults. Our results suggest that these gender differences amongst adults were apparently a gradual build-up from childhood. The results also confirm suggestions that levels of some immunoglobulin types seen amongst African adults may have possibly been attained during childhood. Our study could be of value since previous reports in this regard have been relatively scanty especially in this part of Nigeria.

    Trichodorus zanjanensis n. sp., collected from the rhizosphere of wild almond tree (Amygdalus scoparia Spach) in Zanjan Province, Iran, is described and illustrated based on morphological and molecular data. The new species is characterised by its body length (772-819 μm in males; 704-953 μm in females), and in having medium-sized onchiostyle (60-64 μm in males; 59-65 μm in females) and a short dorsal overlap of the intestine. Males of the new species have two ventromedian cervical papillae posterior to onchiostyle region, ventrally curved spicules, smooth, long and wide manubrium, gradually continuing in a narrower anterior part of the blade provided with bristles and marked from the wider and transversely striated main part of the blade, tapered towards distal end, three ventromedian precloacal supplements, the posterior one (SP1) situated at the level of anterior blade and gubernaculum situated at 24-25 μm from the cloaca. Females have one pair of sublateral body pores in the vulva region, medium rounded triangular to oval sclerotised vaginal pieces in lateral view, and pear-shaped vagina. The new species resembles T. persicus De Waele & Sturhan, 1987, T. minzi De Waele & Cohn, 1992 and T. taylori De Waele, Mancini, Roca & Lamberti, 1982. The results of morphological and morphometric comparisons and molecular data based on sequences of the partial 18S and D2-D3 expansion segments of 28S rRNA genes, clearly separated T. zanjanensis n. sp. from these known species and supported the description of T. zanjanensis n. sp. as a new species.

    Gangemi, Mancini, and van den Hout (2012) argued that anxious patients use safety behaviors as information that the situation in which the safety behaviors are displayed is dangerous, even when that situation is objectively safe. This was concluded from a vignette study in which anxious patients and non-clinical controls rated the dangerousness of scripts that were safe or dangerous and in which the protagonist did or did not display safety behaviors. Patients were more likely to take safety behavior as evidence that the situation was dangerous, especially in safe situations. Their non-clinical group may not have been psychologically naïve. We critically replicated the Gangemi et al. study using a psychologically non-informed control group. The same materials were used and patients (Obsessive Compulsive Disorder, Panic Disorder, Social Phobia; n = 30 per sub-group) were compared to matched non-patients. Using Bayesian statistics, data from the Gangemi et al. samples and the present groups were (re-)analyzed testing the hypothesis relative to non-patients, patients infer threat from safety behaviors, especially if displayed in safe situations. The Gangemi et al. data yielded a Bayes factor of 3.31 in support of the hypothesis. The present Bayes Factor was smaller (2.34), but strengthened the support for the hypothesis expressed by an updated Bayes factor of 3.31 × 2.34 = 7.75. The finding that anxious patients infer threat from safety behaviors, in particular in safe contexts, was corroborated, suggesting one way in which safety behaviors are involved in the maintenance of anxiety disorders.

    Background: Ventilation with continuous positive airway pressure (CPAP) is the gold standard therapy for obstructive sleep apnea (OSA). However, it was recently suggested that a novel mode of ventilation, Bilevel-auto, could be equally effective in treating patients unable to tolerate CPAP. The aim of this study was to investigate the ability of Bilevel-auto to treat OSA patients whose nocturnal ventilatory disturbances are not completely corrected by CPAP. Methods: We enrolled 66 consecutive OSA patients, not responsive to (group A) or intolerant of (group B) CPAP treatment, after a full night of manual CPAP titration in a laboratory. Full polysomnography data and daytime sleepiness score were compared for each group in the three different conditions: basal, during CPAP, and during Bilevel-auto. Results: The apnea-hypopnea index decreased significantly during CPAP in both groups; however, in the group A, there was a further significant improvement during Bilevel-auto. The same trend was observed for oxygenation indices, while the distribution and the efficiency of sleep did not differ following the switch from CPAP to Bilevel-auto. Conclusions: This study confirmed the role of Bilevel-auto as an effective therapeutic alternative to CPAP in patients intolerant of this latter mode of ventilation. Moreover, extending the use of Bilevel-auto to those OSA patients not responsive to CPAP, we showed a significantly better correction of nocturnal respiratory disturbances.

  17. Observation of Interspecies Ion Separation in Inertial-Confinement-Fusion Implosions via Imaging X-ray spectroscopy

    Joshi, Tirtha Raj

    2016-10-01

    Interspecies ion separation has been proposed as a yield-degradation mechanism in inertial-confinement-fusion (ICF) experiments. We present direct experimental evidence of interspecies ion separation in direct-drive ICF experiments performed at the OMEGA laser facility. These experiments were designed based on the fact that interspecies ion thermo-diffusion would be strongest for species with large mass and charge difference. The targets were spherical plastic shells filled with D2 and Ar (1% by atom). Ar K-shell spectral features were observed primarily between the time of first-shock convergence and slightly before neutron bang time, using a time- and space-integrated spectrometer, streaked crystal spectrometer, and two gated multi-monochromatic X-ray imagers fielded along quasi-orthogonal lines-of-sight. Detailed spectroscopic analyses of spatially resolved Ar K-shell lines reveal deviation from the initial 1%-Ar gas fill and show both Ar-concentration enhancement and depletion at different times and radial positions of the implosion. The experimental results are interpreted with radiation-hydrodynamic simulations that include recently implemented, first-principles models of interspecies ion diffusion. The experimentally inferred Ar-atom-fraction profiles agree gently with calculated profiles associated with the incoming and rebounding first shock. This work was done in collaboration with P. Hakel, S. C. Hsu, E. L. Vold, M. J. Schmitt, N. M. Hoffman, R. M. Rauenzahn, G. Kagan, X.-Z. Tang, Y. Kim, and H. W. Herrmann of LANL, and R. C. Mancini of UNR. LA-UR-16-24804.

  18. Experimental investigation of opacity models for stellar interiors, inertial fusion, and high energy density plasmas

    NASA Astrophysics Data System (ADS)

    Bailey, James

    2008-11-01

    Theoretical opacities are required for calculating energy transport in plasmas. In particular, understanding stellar interiors, inertial fusion, and Z-pinches depends on the opacities of mid-atomic-number elements in the 150-300 eV temperature range. These models are complex and experimental validation is crucial. For example, solar models presently disagree with helioseismology and one possible explanation is inadequate opacities. Testing these opacities requires a uniform plasma at temperatures high enough to produce the ion charge states that exist in the sun. Typical opacity experiments heat a sample using x-rays and measure the spectrally resolved transmission with a backlight. The difficulty grows as the temperature increases because the heating x-ray source must supply more energy and the backlighter source must be bright enough to overwhelm the plasma self emission. These problems were overcome using the dynamic hohlraum x-ray source at Sandia's Z facility to measure the transmission of a mixed Mg-Fe plasma heated above 150 eV. This capability will also advance opacity science for other high energy density plasmas. This tutorial describes opacity experiment challenges including accurate transmission measurements, plasma diagnostics, and quantitative model comparisons. The solar interior serves as a focal problem and Z facility experiments are used to illustrate the techniques. **In collaboration with C. Iglesias (LLNL), R. Mancini (U. Nevada), J.MacFarlane, I.

    By combining transport measurements and optical second harmonic generation, we have investigated heterostructures formed between crystalline thin films of LaAlO{sub 3}, with varying stoichiometry and TiO{sub 2}-terminated SrTiO{sub 3}(001) substrates. Optical second harmonic generation directly probes the polarity of these heterostructures, thus complementing the transport data. The stoichiometry and the growth temperature are found to be critical parameters for controlling both the interfacial conductivity and the heterostructure polarity. In agreement with the previous work, all of the samples display an insulator-to-metal transition in the Al-reach region, with the conductivity first increasing and then saturating at the highest Al/La ratios. Themore » second harmonic signal also increases as a function of the Al/La ratio, but, at the highest growth temperature, it does not saturate. This unusual behavior is consistent with the formation of an ordered structure of defect dipoles in the LaAlO{sub 3} film caused by the off-centering of excess Al atoms in agreement with the theory.« less

  10. Laser interferometry of radiation driven gas jets

    2017-06-01

    In a series of experiments performed at the 1MA Zebra pulsed power accelerator of the Nevada Terawatt Facility nitrogen gas jets were driven with the broadband x-ray flux produced during the collapse of a wire-array z-pinch implosion. The wire arrays were comprised of 4 and 8, 10μm-thick gold wires and 17μm-thick nickel wires, 2cm and 3cm tall, and 0.3cm in diameter. They radiated 12kJ to 16kJ of x-ray energy, most of it in soft x-ray photons of less than 1keV of energy, in a time interval of 30ns. This x-ray flux was used to drive a nitrogen gas jet located at 0.8cm from the axis of the z-pinch radiation source and produced with a supersonic nozzle. The x-ray flux ionizes the nitrogen gas thus turning it into a photoionized plasma. We used laser interferometry to probe the ionization of the plasma. To this end, a Mach-Zehnder interferometer at the wavelength of 266 nm was set up to extract the atom number density profile of the gas jet just before the Zebra shot, and air-wedge interferometers at 266 and 532 nm were used to determine the electron number density of the plasma right during the Zebra shot. The ratio of electron to atom number densities gives the distribution of average ionization state of the plasma. A python code was developed to perform the image data processing, extract phase shift spatial maps, and obtain the atom and electron number densities via Abel inversion. Preliminary results from the experiment are promising and do show that a plasma has been created in the gas jet driven by the x-ray flux, thus demonstrating the feasibility of a new experimental platform to study photoionized plasmas in the laboratory. These plasmas are found in astrophysical scenarios including x-ray binaries, active galactic nuclei, and the accretion disks surrounding black holes1.

    2005-10-01

    Dynamic hohlraum experiments at the Z facility already implode capsules with up to 80 kJ absorbed x-ray energy. However, many challenging issues remain for ICF. The present experiments use diagnostic capsules to address two of these issues: symmetry measurement and control and building understanding of the capsule/hohlraum implosion system. A suite of x-ray spectrometers record time and space resolved spectra emitted by Ar tracer atoms in the implosion core, simultaneously from up to three different quasi-orthogonal directions. Comparing the results with simulation predictions provide severe tests of understanding. These data also can used to produce a tomographic reconstruction of the time resolved core temperature and density profiles. X-ray and neutron diagnostics are used to examine how the implosion conditions change as the capsule design changes. The capsule design changes include variations in CH wall thickness and diameter, Ge-doped CH shells, and SiO2 shells. In addition, a new campaign investigating Be capsule implosions is beginning. Be capsules may offer superior performance for dynamic hohlraum research and it may be possible to investigate NIF-relevant Be implosion issues such as the fill tube effects, sensitivity to columnar growth associated with sputtered Be capsule fabrication, and the effect of Cu dopants on implosion conditions.

    Il dato dell'Organizzazione per la cooperazione e lo sviluppo economico (OCSE) del 2012, che indicava l'Italia come il Paese con la più bassa spesa in prevenzione sanitaria, ha dato lo spunto per una raccolta sistematica e un'analisi critica dei flussi disponibili sulla spesa per le attività di prevenzione in Italia. Le statistiche correnti di spesa sanitaria sono raccolte centralmente dall'Agenzia nazionale per i servizi sanitari regionali (Agenas) attraverso i modelli di rilevazione dei costi dei livelli essenziali di assistenza (LEA) delle aziende USL. Le tre macroaree dei LEA sono: assistenza distrettuale, assistenza ospedaliera e assistenza sanitaria collettiva in ambiente di vita e di lavoro. Le spese per la prevenzione rientrano in quest'ultima e sono ripartite nelle seguenti voci: attività di prevenzione rivolte alle persone, igiene degli alimenti e della nutrizione, igiene e sanità pubblica, prevenzione e sicurezza negli ambienti di lavoro, sanità pubblica veterinaria, attività medico-legale per finalità pubblica. Tra il 2006 e il 2013, ultimo dato disponibile, la spesa per le attività di prevenzione del Servizio sanitario nazionale (SSN) è rimasta costante in rapporto alla spesa sanitaria totale (4,2%), pari a 4,9 miliardi nel 2013. Nel periodo di studio considerato (2006-2013) appaiono in aumento le spese per le attività rivolte alle persone (+8,7%), attribuibili soprattutto a vaccinazioni e screening, e in diminuzione le attività di igiene pubblica (-5,7%) e quelle della sanità pubblica veterinaria (-3,8%). I confronti internazionali indicano una spesa per la prevenzione del 2,9% rispetto alla spesa sanitaria totale, costante negli anni e nella media dei Paesi OCSE. Per la prevenzione, l'Italia spende tanto quanto i Paesi che non possiedono un servizio sanitario pubblico; il dato risulta inferiore del 5% rispetto alla programmazione nazionale, con poche eccezioni e molta variabilità regionale all'interno delle componenti delle voci di spesa

    Contemporary natural resource management requires consideration of the social acceptability of management practices and conditions. Agencies wishing to measure, respond to, and influence social acceptability must understand the nuances of public perception regarding controversial issues. This study explores social acceptability judgments about one such issue: reduction of wildland fuel hazards on federal lands in the western United States. Citizens were surveyed in four locations where fire has been a significant ecological disturbance agent and public land agencies propose to reduce wildland fuel levels and wildfire hazards via prescribed burning, thinning, brush removal, and/or livestock grazing. Respondents in different locations differed in their knowledge about fire and fuel issues as well in their acceptability judgments. Differences are associated with location-specific social and environmental factors as well as individual beliefs. Results argue against using a??one-size-fits-alla?? policies or information strategies about fuels management.

  14. L'eliosismologia: onde sismiche per studiare l'interno del Sole

    Negli ultimi cinquanta anni siamo stati testimoni di una straordinaria rivoluzione della conoscenza e comprensione della nostra stella grazie alla nascita dell'Eliosismologia, lo studio delle oscillazioni solari. Analogamente a ciò che accade nella Terra durante i terremoti, anche l'interno del Sole è pervaso continuamente da onde sismiche che provocano piccole oscillazioni, ovvero deformazioni della fotosfera. Le oscillazioni sono la manifestazione di diversi processi che avvengono all'interno della struttura del Sole e le frequenze sismiche dei modi osservati e misurati sulla superficie sono legate direttamente ai parametri fisici degli strati interni attraversati dalle onde sismiche. Lo studio delle oscillazioni rappresenta, quindi, l'unico metodo diretto per studiare la struttura e la dinamica interna del Sole. In questo articolo verranno illustrate le caratteristiche generali delle oscillazioni solari e verranno presentati i risultati importanti e i progressi notevoli raggiunti grazie all'Eliosismologia.

    To simplify body weight measurement and, particularly, to encourage children and their parents to participate in the Italian nutritional surveillance system OKkio alla SALUTE, children were measured with clothes and then the weight was corrected for the estimated weight of the clothes. In the present study we compared the children's weight measured in underwear, as recommended by the WHO (WWHO), with that obtained using the OKkio alla SALUTE protocol (WOK) and investigated how the latter affects the calculation of BMI and the assessment of overweight and obesity prevalence. Weight (twice in close sequence, with and without clothing) and height were measured. A checklist was used to describe the type of clothing worn. The estimated weight of clothing was subtracted from the WOK. BMI was calculated considering both values of weight and height; ponderal status was defined using both the International Obesity Task Force and WHO BMI cut-offs. Thirty-seven third grade classes of thirteen primary schools in Rome and in two towns in the Lazio Region were recruited. The anthropometric measurements were taken on 524 children aged 8-9 years. The error in the calculation of BMI from WOK was very low, 0·005 kg/m2 (95 % CI -0·185, 0·195 kg/m2); the agreement between the percentages of overweight (not including obesity) and obese children calculated with the two methods was very close to 1 (κ = 0·98). The error in BMI and in nutritional classification can be considered minor in a surveillance system for monitoring overweight/obesity, but eases the procedure for measuring children.

    In recent years, effective models of disaster medicine curricula for medical schools have been established. However, only a small percentage of medical schools worldwide have considered at least basic disaster medicine teaching in their study program. In Italy, disaster medicine has not yet been included in the medical school curriculum. Perceiving the lack of a specific course on disaster medicine, the Segretariato Italiano Studenti in Medicina (SISM) contacted the Centro di Ricerca Interdipartimentale in Medicina di Emergenza e dei Disastri ed Informatica applicata alla didattica e alla pratica Medica (CRIMEDIM) with a proposal for a nationwide program in this field. Seven modules (introduction to disaster medicine, prehospital disaster management, definition of triage, characteristics of hospital disaster plans, treatment of the health consequences of different disasters, psychosocial care, and presentation of past disasters) were developed using an e-learning platform and a 12-hour classroom session which involved problem-based learning (PBL) activities, table-top exercises, and a computerized simulation (Table 1). The modules were designed as a framework for a disaster medicine curriculum for undergraduates and covered the three main disciplines (clinical and psychosocial, public health, and emergency and risk management) of the core of "Disaster Health" according to the World Association for Disaster and Emergency Medicine (WADEM) international guidelines for disaster medicine education. From January 2011 through May 2013, 21 editions of the course were delivered to 21 different medical schools, and 524 students attended the course. The blended approach and the use of simulation tools were appreciated by all participants and successfully increased participants' knowledge of disaster medicine and basic competencies in performing mass-casualty triage.

  17. The orbital record in stratigraphy

    Fischer, Alfred G.

    1992-01-01

    Orbital signals are being discovered in pre-Pleistocene sediments. Due to their hierarchical nature these cycle patterns are complex, and the imprecision of geochronology generally makes the assignment of stratigraphic cycles to specific orbital cycles uncertain, but in sequences such as the limnic Newark Group under study by Olsen and pelagic Cretaceous sequence worked on by our Italo-American group the relative frequencies yield a definitive match to the Milankovitch hierarchy. Due to the multiple ways in which climate impinges on depositional systems, the orbital signals are recorded in a multiplicity of parameters, and affect different sedimentary facies in different ways. In platform carbonates, for example, the chief effect is via sea-level variations (possibly tied to fluctuating ice volume), resulting in cycles of emergence and submergence. In limnic systems it finds its most dramatic expression in alternations of lake and playa conditions. Biogenic pelagic oozes such as chalks and the limestones derived from them display variations in the carbonate supplied by planktonic organisms such as coccolithophores and foraminifera, and also record variations in the aeration of bottom waters. Whereas early studies of stratigraphic cyclicity relied mainly on bedding variations visible in the field, present studies are supplementing these with instrumental scans of geochemical, paleontological, and geophysical parameters which yield quantitative curves amenable to time-series analysis; such analysis is, however, limited by problems of distorted time-scales. My own work has been largely concentrated on pelagic systems. In these, the sensitivity of pelagic organisms to climatic-oceanic changes, combined with the sensitivity of botton life to changes in oxygen availability (commonly much more restricted in the Past than now) has left cyclic patterns related to orbital forcing. These systems are further attractive because (1) they tend to offer depositional continuity

    . Seventy-five percent of the gas is estimated to be from late cracking of oil in the source rock. Lewan (2002) concluded that much of the thermogenic gas produced in this basin is the result of cracking of oil to gas in deeply buried reservoirs. The efficiency of expulsion, migration and trapping has been estimated to range from 0.5 to 10 percent for certain basins (Schmoker, 1994: Zimmerman, 1999). The estimate of the total hydrocarbons generated for the Mississippi Interior Salt Basin is 910 billion barrels using the method of Schmoker (1994), and the estimate of the total hydrocarbons generated is 1,540 billion barrels using the Platte River software application. The estimate of gas generated for this basin is 3,130 TCF using the Platte River software application, and 4,050 TCF using the method of Schmoker (1994). Seventy-five percent of the gas is estimated to be from late cracking of oil in the source rock. Claypool and Mancini (1989) report that the conversion of oil to gas in reservoirs is a significant source of thermogenic gas in this basin. The Manila and Conecuh Subbasins are oil-prone. Although these subbasins are thermally mature for oil generation and expulsion, they are not thermally mature for secondary, non-associated gas generation and expulsion. The gas produced from the highly productive gas condensate fields (Big Escambia Creek and Flomaton fields) in these subbasins has been interpreted to be, in part, a product of the cracking of oil to gas and thermochemical reduction of evaporite sulfate in the reservoirs (Claypool and Mancini, 1989). The areas in the North Louisiana and Mississippi Interior Salt Basins with high potential for deeply buried gas reservoirs (>15,000 ft) have been identified. In the North Louisiana Salt Basin, these potential reservoirs include Upper Jurassic and Lower Cretaceous facies, especially the Smackover, Cotton Valley, Hosston, and Sligo units.

    The MAPK p38 became a focal point of inflammatory research when it was recognized that it played a key role in the production of the pro-inflammatory molecules TNF-alpha, IL-beta, and cyclooxygenase-2 (COX-2). The pharmaceutical industry devoted enormous efforts to creating p38 inhibitors, because blocking p38 had the potential of downregulating a group of pro-inflammatory mediators, and thus, one drug could have a cocktail effect. The market potential seemed to be clearly established (Bonafede et al., Clinicoecon Outcomes Res 6:381-388, 2014) with a multiplicity of TNF-alpha antibodies and a soluble receptor (Mewar and Wilson, Br J Pharmacol 162:785-791, 2011) already on the market, although the relationship between TNF-alpha production and p38 activation is a complicated two-way (Sabio and Davis, Semin Immunol 26:237-245, 2014) signal transduction process. With the discovery that activated p38 stabilizes (Mancini and Di Battista, Inflamm Res 60:1083-1092, 2011) COX-2 mRNA and upregulates expression of IL-beta (Bachstetter and Van Eldik, Aging Dis 1:199-211, 2010) probably in a similar manner, inhibiting p38 appeared to be a way of blocking TNF-alpha, COX-2, and IL-beta simultaneously. At Locus Pharmaceuticals we jumped on this opportunity, because we believed that our fragment-based drug discovery approach was ideally suited for making a potent small molecule p38 inhibitor that did not bind in the ATP site, but also had the solubility, lack of planarity, and low molecular weight required of a clinical candidate. Just to be clear, in our experience highly planar compounds often result in poor pharmacokinetics, because they tend to bind strongly to plasma proteins. At Locus we typically repeated assays by adding increasing amounts of plasma to check for potency degradation in the presence of blood. We found this to be a useful early indicator of pharmacokinetics and in vivo behavior. It became clear from our work and the work of others that binding to the ATP site

    2,4-Hexadienoyl-coenzyme A (HD-CoA) has been used to investigate the redox and ionization properties of medium-chain acyl-CoA dehydrogenase (MCAD) from pig kidney. HD-CoA is a thermodynamically stabilized product analogue that binds tightly to oxidized MCAD (K(dox) = 3.5 +/- 0.1 microM, pH 7.6) and elicits a redox potential shift that is 78% of that observed with the natural substrate/product couple [Lenn, N. D., Stankovich, M. T., and Liu, H. (1990) Biochemistry 29, 3709-3715]. The midpoint potential of the MCAD.HD-CoA complex exhibits a pH dependence that is consistent with the redox-linked ionization of two key glutamic acids as well as the flavin adenine dinucleotide (FAD) cofactor. The estimated ionization constants for Glu376-COOH (pK(a,ox) approximately 9.3) and Glu99-COOH (pK(a,ox) approximately 7.4) in the oxidized MCAD.HD-CoA complex indicate that while binding of the C(6) analogue makes Glu376 a stronger catalytic base (pK(a,ox) approximately 6.5, free MCAD), it has little effect on the pK of Glu99 (pK(a,ox) approximately 7.5, free MCAD) [Mancini-Samuelson, G. J., Kieweg, V., Sabaj, K. M., Ghisla, S., and Stankovich, M. T. (1998) Biochemistry 37, 14605-14612]. This finding is in agreement with the apparent pK of 9.2 determined for Glu376 in the human MCAD.4-thia-octenoyl-CoA complex [Rudik, I., Ghisla, S., and Thorpe, C. (1998) Biochemistry 37, 8437-8445]. The pK(a)s estimated for Glu376 and Glu99 in the reduced pig kidney MCAD.HD-CoA complex, 9.8 and 8.6, respectively, suggest that both of these residues remain protonated in the charge-transfer complex under physiological conditions. Polarization of HD-CoA in the enzyme active site may contribute to the observed pK(a) and redox potential shifts. Consequently, the electronic structures of the product analogue in its free and MCAD-bound forms have been characterized by Raman difference spectroscopy. Binding to either the oxidized or reduced enzyme results in localized pi-electron polarization of the

    In the last three decades, climate change and human activities increased desertification process in Mediterranean regions, with dramatic consequences for agriculture and water availability. For instance in the Flumendosa reservoir system in Sardinia the average annual runoff in the latter part of the 20th century was less than half the historic average rate, while the precipitation over the Flumendosa basin has decreased, but not at such a drastic rate as the discharge, suggesting a marked non-linear response of discharge to precipitation changes. With the objective of analyzing and looking for the reasons of the historical runoff decrease a new ecohydrological model is developed and tested for the main basin of the Sardinia island, the Flumendosa basin. The eco-hydrological model developed couples a distributed hydrological model and a vegetation dynamic model (VDM). The hydrological model estimates the soil water balance of each basin cell using the force-restore method and the Philips model for runoff estimate. Then it computes runoff propagation along the river network through a modified version of the Muskingum -Cunge method (Mancini et al., 2000; Montaldo et al., 2004). The VDM evaluates the changes in biomass over time from the difference between the rates of biomass production (photosynthesis) and loss (respiration and senescence), and provides LAI, which is then used by the hydrological model for evapotranspiration and rainfall interception estimates. Case study is the Flumendosa basin (Sardinia, basin area of about 1700 km2), which is characterized by a reservoir system that supplies water to the main city of Sardinia, Cagliari. Data are from 42 rain stations (1922-2008 period) over the entire basin and data of runoff are available for the same period. The model has been successfully calibrated for the 1922 - 2008 period for which rain, meteorological data and discharge data are available. We demonstrate that the hystorical strong decrease of runoff is

    Throughout the world and particularly in sub-Saharan Africa, deficiencies in trace elements constitute a real public health problem because of the insufficient nutritional quality of food. These trace elements are necessary for many of the body's biochemical reactions. The role of microelements such as vitamin A and zinc has been established in the functioning of the immune system and secretion of inflammatory reaction proteins, but the role of iron in these functions remains to be elucidated. The sample consists of 186 children (3/4) 80 with an iron deficiency and 106 with normal iron status. They range in age from 5 to 15 years and all attend school in the department of Adzope. The study excluded all children with parasites that might affect blood iron, protein and other hematological indicators, in particular, Plasmodium falciparum, Giardia intestinalis, Trichomonas intestinalis, Ascaris lumbricoides, and Ancylostoma. Inflammatory, immune and nutritional proteins were measured by radial immunodiffusion (Mancini's method). Ferritin was measured by a specific immunoenzymatic assay. Hematological indicators were tested by an automatic blood cell counter. Nutritional status was estimated by the weight/height ratio (W/H). This analysis showed that iron deficiency was associated with reduced IgG levels (p < 0.05), although immunoglobulins A and M remained stable (p > 0.05. Iron deficiency was also associated with reduced levels of thyroxine-binding prealbumin (TBPA) and albumin (p < 0.05). Inflammatory proteins did not differ significantly between the two groups (p > 0.05). Furthermore, the prognostic inflammatory and nutritional index (PINI) did not show any inflammatory, vital or nutritional risk, because it was lower than or equal to 2. Finally, malnutrition was not observed in the iron-deficient children: the difference in the weight/height ratio (W/H = 96.58 +/- 2.4%) between the children with iron deficiency and those with normal iron status (98.7 +/- 4.3%) did

Significantly different lambda values were also observed for the anaerobic degradation of xylenes initiated by the BSS [5]. The different lambda values obtained for the anaerobic degradation of toluene and xylenes might be caused by slightly different reaction mechanisms of BSS isoenzymes. In comparison, lambda and/or ɛbulk values for the methyl monohydroxylation of toluene with oxygen as co-substrate were significantly different for two tested strains each containing a different toluene attacking enzyme, indicating that specific enzymes for aerobic methyl group oxidation reactions can be detected by CSIA and 2D-CSIA. Our results show that the combined carbon and hydrogen isotope fractionation approach has great potential to elucidate biodegradation pathways of monoaromatic hydrocarbons in microcosm and field studies. Current work focus on (i) 2D-CSIA of aromatic and aliphatic hydrocarbons in degradation experiments using whole cells, and (ii) 2D-CSIA of aromatic hydrocarbons in in vitro experiments using cell extracts.

    È pleonastico ricordare che ogni individuo raziocinante delle essere responsabile delle sue azioni: deve agire con la coscienza degli scopi che si propone evitando possibili conseguenze negative dei suoi atti. In ambito medico questo tipo di responsabilità è codificata con le norme della "deontologia". Per secoli l'arte terapeutica è stata praticata da individui dotati di una particolare vocazione ed una particolare cultura acquisita da Maestri dell'arte ancor prima che dalla propria esperienza, con nozioni di erboristeria e di elementari conoscenze anatomiche e di fisiologia, circondati da un'aura sacerdotale e da un rispetto derivante dal timore e dall'ammirazione per il coraggio e auspicabilmente dai successi, e facendo riferimento nell'occidente mediterraneo alle regole operative fissate nel Giuramento di Ippocrate, di significato tra il sacro ed il deontologico. Lo sviluppo delle tecniche anestesiologiche a partire dalla seconda metà dell'800 ha determinato l'ampliamento delle iniziative chirurgiche di tipo elettivo, a fianco con gli storici interventi in emergenza per la cura di lesioni traumatiche, ancor prima delle acquisizioni riguardanti le infezioni. Con l'espansione del campo di azione della chirurgia, le possibili complicanze ed i possibili insuccessi hanno fatto da contrappeso ai sentimenti di rispetto e di fiducia nei confronti dei chirurghi, giungendo a far assimilare in tali casi la loro opera quale causa all'origine di danni, provocati rientrando quindi nella categoria dei reati sottoposti alla Legge penale. Così, al termine deontologico di "responsabilità" valido per ogni iniziativa ed ogni professione, per i medici è venuto ad associarsi la qualifica di "professionale", con un significato di presunta colpevolezza. Da una parte le regole deontologiche si sono ampliate, ed hanno coinvolto direttamente il paziente nella fase decisionale delle terapie chirurgiche, formalizzate programmaticamente in moderni codici deontologici ed

    a range of magnetic properties in ZnO can result, depending on the sample preparation and annealing conditions. For example, within the same ZnO sample we have observed ferro- to para- and diamagnetic responses depending on the annealing conditions. We also explored the effects of surface states on the magnetic behavior of nanoscale ZnO through detailed calculations. In the case of grapheme, we have observed new combination modes in the range from 1650 to 2300 cm-1 in single-(SLG), bi-, few-layer and incommensurate bilayer graphene (IBLG) on silicon dioxide substrates. A peak at ˜1860 cm-1 (iTALO- ) is observed due to a combination of the in-plane transverse acoustic (iTA) and the longitudinal optical (LO) phonons. The intensity of this peak decreases with increasing number of layers and this peak is absent for bulk graphite. The overtone of the out-of-plane transverse optical (oTO) phonon at ˜1750 cm-1, also called the M band, is suppressed for both SLG and IBLG. In addition, two previously unidentified modes at ˜2200 and ˜1880 cm-1 are observed in SLG. The 2220 cm -1 (1880 cm-1) mode is tentatively assigned to the combination mode of in-plane transverse optical (iTO) and TA phonons (oTO+LO phonons) around the K point in the graphene Brillouin zone. Finally, the peak frequency of the 1880 (2220) cm-1 mode is observed to increase (decrease) linearly with increasing graphene layers. Finally, we find that the high curvature in sub-nm SWCNTs leads to (i) an unusual S-like dispersion of the G-band frequency due to perturbations caused by the strong electron-phonon coupling, (ii) an activation of diameter-selective intermediate frequency modes that are as intense as the radial breathing modes (RBMs), and (iii) a clear observation of the IR modes.

    Taking into account the recognized interest of a poly-pharmacological strategy in chelation therapy, a study of aluminium combined chelation based on 3-hydroxy-4-pyridinone (3,4-HP) compounds with complementary properties, associated to different denticity, size and extrafunctionality, is presented herein. In particular, Al-chelation has been explored, using a tetradentate IDA bis-(3,4-HP) ligand, L, and two N-glycosyl mono-(3,4-HP) derivatives (A or B). Combined complexation studies with the tetradentate and the most promising bidentate ligand (A) evidenced the formation of ternary complexes with high thermodynamic stability (Al-L-A) being the predominant species at physiological pH. In vivo studies on the ability for radiotracer ((67)Ga) removal from loaded mice, as a model of aluminium accumulation in body, have shown that the simultaneous administration to (67)Ga-loaded mice of a mono- and a bis-(3,4-HP) chelator (e.g. A and L) leads to a rapid metal elimination from main organs and whole animal model. This may be rationalized by coadjuvation and eventual synergistic effects, due to complementary accessibility of the chelators to different cellular compartments.

    Proposed Ignitor burning plasma experiment is characterized by almost ideal alignment of the magnetic field to the first wall. This leads to a situation, when sheath is parallel to the magnetic field, and its structure is determined by cross-field plasma transport. High magnetic field and relatively high plasma density (and temperature) make electron gyro-orbits and Debye length comparable, while ion Larmor radius is two orders bigger. We simulate collisionless ''parallel'' sheath for the typical Ignitor parameters using time-dependent two-dimensional in both real space and velocity Fokker-Planck code ALLA [1]. We treat both electrons and ions self-consistently. The rectangular simulation domain has 100-1000 Debye dimensions. Time scale is a fraction of the lowest of the electron plasma and electron gyration periods. Self-consistent electric field is obtained through Poisson equation. We observe sheath formation, its time evolution (oscillations), and calculate sheath-transmission coefficients to be used in the fluid codes. [1] O.V.Batishchev et al., J.

    The so-called "hot spots" formed in a plasma heated by lasers having transverse spatial modulations give rise to steep temperature gradients with the scale comparable to the electron-ion mean free path. This indicates that the nonlocal transport effects can be important. Both the spatial transport and non-uniform heating of electrons by strong laser field may cause significant deviation of the electron distribution function (EDF) from the Maxwellian [1,2]. To study inhomogeneous hot spot formation we deploy 1D2V Fokker-Planck code ALLA [3], which includes e-e and e-i collisions, ambipolar electric field, and inverse bremsstrahlung plasma heating. Unlike particle methods it's free of statistical fluctuations and allows more accurate resolution of the EDF tail that is important to study the reduction of the electron plasma wave damping. We present results of the kinetic simulations with hot spots of various shapes and intensities, as well as a comparison with the results for homogeneous plasma heating and analytical models for EDF in high Z-plasmas.

All these are elements of an exemplar case of misannotation in biological databases and confusion in the scientific literature concerning genes and enzymes acting on ureidoglycolate, an intermediate of purine catabolism. Here we show biochemical evidence for the relocation of genes assigned to EC 3.5.3.19 (ureidoglycolate hydrolase, releasing ammonia), such as allA of Escherichia coli or DAL3 of Saccharomyces cerevisiae, to EC 4.3.2.3 (ureidoglycolate lyase, releasing urea). The EC 3.5.3.19 should be more appropriately named ureidoglycolate amidohydrolase and include genes equivalent to UAH of Arabidopsis thaliana. The distinction between ammonia- or urea-releasing activities from ureidoglycolate is relevant for the understanding of nitrogen metabolism in various organisms and of virulence factors in certain pathogens rather than a nomenclature problem. We trace the original fault in database annotation and provide a rationale for its incorporation and persistence in the scientific literature. Notwithstanding the technological distance, yet not surprising for the constancy of human nature, error categories and mechanisms established in the study of the work of amanuensis monks still apply to the modern curation of biological databases.

    In this paper we consider the inverse problem of determining, within an elastic isotropic thick plate modelled by the Reissner-Mindlin theory, the possible presence of an inclusion made of a different elastic material. Under some a priori assumptions on the inclusion, we deduce constructive upper and lower estimates of the area of the inclusion in terms of a scalar quantity related to the work developed in deforming the plate by applying simultaneously a couple field and a transverse force field at the boundary of the plate. The approach allows us to consider plates with a boundary of Lipschitz class. The first author is supported by PRIN 2015TTJN95 ‘Identification and monitoring of complex structural systems’.

    The objectives of this study are to investigate the impact of papermaking sludge product (LA) on coagulation performance and floc properties under different solution pH and hydraulic conditions. LA was synthetized by grafting acrylamide onto the lignin that contained in papermaking sludge. Characterization of LA, such as FTIR, SEM, zeta potential and molecular weight, showed that target product was obtained successfully. LA was used in combination with aluminum sulfate or polyaluminum chloride, namely Al-LA (Al was dosed firstly) and LA-Al (LA was dosed firstly), in humic acid water treatment. Floc properties and coagulation behaviors of aluminum salts and the dual-coagulants were comparatively evaluated. Results showed that DOC removal was improved by LA at pH 4 ~ 9 and the removal variations caused by different pH were decreased. Flocs formed at pH 5 and pH 8 gave quite large floc size. Floc recoverability declined as initial pH increased. Floc size, growth rate and recoverability were in the order of Al-LA>LA-Al>Al. Furthermore, flocs formed at pH 7 showed the weakest resistance to increasing shear force. Fractal dimension was rather high at pH 7 and 8 and it was in the following order: Al>LA-Al>Al-LA.

    Historical buildings are a significant part of the Italian building stock and, in most cases, need deep refurbishment interventions to reach the energy criteria required by the current standards. A workflow that integrates on-site surveys and building modeling is mandatory to obtain effective energy saving measures. This work describes the analysis and modeling of the San Vito alla Rivera church, a XIV century building that was damaged during 2009 L'Aquila earthquake, suffering a partial collapse of the façade and of the roof. The latter was selected for a complete restoration that could improve its thermal performance while maintaining, as much as possible, the original structure. Several elements of the roof were collected in situ in order to measure, in laboratory, its thermophysical properties applying standard techniques and alternative methods based on infrared thermography. The accurate characterization of the materials was the starting point for the estimation of the environmental impact of the retrofit aimed to reach a defined thermal transmittance. A model of the building was created with TRNSYS software to calculate the energy consumption before and after the intervention. A Life Cycle Assessment (LCA) analysis was conducted on different insulation materials to determine the one with the lowest impact.

    Freight wagons are usually equipped with the standard Union Internationale des Chemins de Fer pneumatic brake. On long trains, the propagation of the pneumatic signals along the pipe and different braking/loading conditions may produce delays and/or differences in the application of the braking effort along the train. This phenomenon may cause heavy longitudinal forces exchanged between wagons through buffers and draw gear. In particular, the workgroup n.6 (freight trains composition) of the Italcertifer committee has performed some preliminary studies concerning the application of LL braking operative conditions on freight wagons trains travelling on Italian lines. Partners have cooperated in this workgroup; however, in this paper, the attention is focused on methodologies and results concerning the contribution of University of Florence. The results of this activity, coordinated by RFI-CESIFER have been used to emanate the 20/07 rule of the RFI ('Modifiche alla Prefazione Generale all'Orario di Servizio') which modify the composition criterion rules of freight trains on the Italian Railways in order to introduce and discipline the application of the LL braking operative condition.

    Classical ballet is an art form requiring extraordinary physical activity, characterised by rigorous training. These can lead to many overuse injuries arising from repetitive minor trauma. The purpose of this paper is to report our experience in the diagnosis and treatment of stress fractures at the base of the second and third metatarsal bones in young ballet dancers. We considered 150 trainee ballet dancers from the Ballet Schools of "Teatro Alla Scala" of Milan from 2005 to 2007. Nineteen of them presented with stress fractures of the base of the metatarsal bones. We treated 18 dancers with external shockwave therapy (ESWT) and one with pulsed electromagnetic fields (EMF) and low-intensity ultrasound (US); all patients were recommended rest. In all cases good results were obtained. The best approach to metatarsal stress fractures is to diagnose them early through clinical examination and then through X-ray and MRI. ESWT gave good results, with a relatively short time of rest from the patients’ activities and a return to dancing without pain. PMID:19415273

    E' noto che le regioni centrali degli ammassi e gruppi di galassie costituiscono un ambiente in cui gas caldo e plasma radioemittente proveniente dalle galassie dominanti interagiscono tra loro. In particolare, si pensa che la radioemissione dell'AGN centrale ed i suoi possibili cicli di attivita', siano strettamente legati alla presenza di cavita' e "bubbles" nel gas intergalattico. Si presentera' lo status di un progetto osservativo effettuato con il Giant Metrewave Radio Telescope (GMRT, India) su di un campione di 18 gruppi di galassie, osservati a tre frequenze radio (235 MHz, 325 MHz e 610 MHz). Lo studio della morfologia radio degli AGN centrali e la relativa analisi spettrale permettono di ottenere stime sull'eta' di questi oggetti, e sulla loro energia totale, che a loro volta sono in relazione con le proprieta' X dei gruppi stessi. Per tutti gli oggetti del campione sono disponibili osservazioni Chandra di proprieta'. Per due oggetti del campione, 4C+24.36 (al centro di AWM04) e NGC741 (al centro di RSOG17) verra' presentato uno studio dettagliato.

    In the ambit of our program of researches on ancient rivers in Ferrara hinterland (Italy), we have been joining a Scientific - Didactic Project between Soprintendenza per i Beni Archeologici dell'Emilia Romagna, Comune di Portomaggiore Assessorato alla Cultura, CMAS A.CDCI. - Confédération Mondiale des Activités Subaquatiques Federation ITA F07 - Associazione CMAS Diving Center Italia. The Project is focused on underwater archaeological surveys in ex quarry lakes, following the Rivers Padus and Sandalus between Voghiera, Gambulaga and Portomaggiore (Ferrara District). Here we are going to introduce our most recent results, after the last immersions and a 3D bathymetrical survey completed by echo-side scan sonar in Tramonto Lake at Gambulaga, explaining the connection with remote sensing investigations and direct surveys applied to underwater archaeology of the inland water. The main submerged structure individuated is a part of wooden dock on the left side of Padus, in front of the Necropolis of Fadieni (1st-3rd cent. A.D.). Thanks to the study of 183 finds coming from the lake, involving students and young collaborators of the Archaeological National Museum of Ferrara, we are reconstructing the ancient landscape between Proto-Imperial Age and Late Antique.

  19. How changes in nutrition have influenced the development of allergic diseases in childhood

    PubMed Central

    2012-01-01

    The increasing prevalence of allergic diseases in childhood in the last decades could be linked to concomitant dietary changes, especially with the modified and lower consumption of fruit, vegetables and minerals. The consumption of these foods by pregnant women and children in the first years of life seems to be associated with a reduced risk of asthma and related symptoms. Foods that can prevent the development of wheezing through their antioxidant effects contain vitamin C and selenium; blood levels of these elements correlate negatively with the risk of wheezing. Intake of vitamin E during pregnancy also appears to be correlated with a reduced risk of wheezing for the unborn child. Similarly, low intake of zinc and carotenoids by pregnant women is associated with an increased risk of wheezing and asthma in childhood. Fiber also has anti-inflammatory properties and protective effects against allergic diseases such as atopic dermatitis and asthma. The consumption of fat influences the development of the airways. Populations in Western countries have increased their consumption of n-6 PUFAs and, in parallel, reduced n-3 PUFAs. This has led to decreased production of PGE2, which is believed to have a protective effect against inflammation of the airways. Conflicting hypotheses also concern vitamin D; both an excess and a deficiency of vitamin D, in fact, have been associated with an increased risk of asthma. Further studies on the role of these substances are necessary before any conclusions can be drawn on a clinical level. Astratto La crescente prevalenza negli ultimi decenni delle malattie allergiche in età pediatrica potrebbe essere legata a concomitanti cambiamenti nella dieta, in particolare alla minore e modificata introduzione di frutta, verdura e minerali. Il consumo di questi alimenti da parte delle donne in gravidanza e dei bambini nei primi anni di vita sembra essere associato ad un ridotto rischio di asma e di sintomi correlati. Gli alimenti che

    This presentation aims to outline the preliminary findings related to an extensive seismic survey conducted in the historical center of Venice, Italy. The survey was conducted via noninvasive and low-cost seismic techniques based on surface waves analysis and microtremor methods, mainly using single station horizontal to vertical spectral ratio techninques (HVSR) and multichannel analysis of surface waves in passive (ReMI) and active (MASW) configurations. The importance and the fragility of the cultural heritage of Venice, coupled with its peculiar geological and geotechnical characteristics, stress the importance of a good knowledge of its geological architecture and seismic characteristics as an opportunity to improve restoration and conservation planning. Even if Venice is located in a relatively low seismic hazard zone, a local characterization of soil resonance frequencies and surficial shear waves velocities could improve the planning of engineering interventions, furnishing important information on possible local effects related to seismic amplification and possible coupling within buildings and soil resonance frequencies. In the specific we collected more than 50 HVSR single station noise measurements and several passive and active multichannel analysis of surface waves located in the historical center. In this work we report the characteristics of the conducted seismic surveys (instrumentation, sampling geometry, etc.) and the preliminary findings of our analysis. Moreover, we discuss briefly the practical issues, mainly of logistic nature, of conducting this kind of surveys in a peculiar and crowed historical center as represented by Venice urban contest.

  1. Meningococco B: controllo di due focolai epidemici mediante vaccinazione

    2014-01-01

    Riassunto La problematica di un efficace approccio vaccinale nei confronti del Meningococco B (MenB) è stata superata identificando con la metodica della "reverse vaccinology" alcuni antigeni capaci di indurre una risposta verso la maggior parte dei ceppi di MenB circolanti nel mondo. Il nuovo vaccino MenB a 4 componenti (4CMenB) è stato autorizzato in Europa, Australia e Canada, ed è entrato nei calendari di immunizzazione pediatrica internazionali: Australia, Canada, UK. In Italia, le prime regioni che hanno raccomandato la vaccinazione contro il MenB sono state Basilicata e Puglia. La gestione di epidemie/focolai epidemici richiede la messa in atto di una risposta rapida da parte delle autorità sanitarie nei confronti di una emergenza sanitaria ad elevato impatto, anche emotivo, sulla popolazione, come recentemente dimostrato in due università americane. Alla dichiarazione di focolaio epidemico in atto, in entrambi i contesti si è attivata una procedura per l'uso del vaccino 4CMenB non ancora autorizzato negli USA. È stato così possibile organizzare gli interventi di profilassi attiva nei due campus universitari, adottando il primo impiego su larga scala del nuovo vaccino 4CMenB e conseguendo, in tempi relativamente brevi, elevati tassi di copertura vaccinale. A fronte di circa 14000 studenti immunizzati con almeno una dose, non è stata segnalata alcuna problematica di eventi avversi conseguenti all'immunizzazione; ad oggi non si sono verificati casi nei soggetti che hanno ricevuto il vaccino. Come conseguenza dei due focolai descritti, è oggi in corso la valutazione da parte dell'FDA per l'estensione dell'uso del vaccino 4CMenB negli Stati Uniti negli adolescenti e giovani adulti.

    Background In 2006 in Italy 2,404,267 donations of blood components were made by 1,539,454 donors; approximately 55% of the donations were collected directly by Transfusion Structures (TS), while about 45% were collected in Donation Centres managed by Associations and Federations of Donors. The aim of the READ (Rilevamento Eventi Avversi alla Donazione) project is to create a network of TS to test a standardised system for monitoring adverse events (AE) related to blood donations. Materials and methods Shared, standardised data collection forms, compatible with the forms produced by the ISBT-EHN, were prepared. Two types of form were used: (i) a form to collect data on single events (READ 1), to be used at the individual collection sites; (ii) a form for processing the data collected by each TS (READ 2). Results Between February and August 2008 six TS collected data related to the donation of 89,332 units of blood. Overall, 523 AE were recorded. The AE occurred in 0.59% of the donations. The mean duration of the symptoms was 17 minutes. Fifteen percent of the symptoms were related to the venipuncture (mainly haematomas) and 77% to vasovagal AE. The AE were defined severe (grade C) in 47 cases. The donations in which AE were recorded were completed in 81% of the cases; 59% of the AE did not require treatment. Three donors were monitored briefly (for less than 4 hours) in hospital. Conclusions The use of standardised forms enabled the collection of data that could be analysed. Some problems related to the performance of the haemovigilance programme did, however, emerge: (i) organisational problems, (ii) limited sensitivity, (iii) inadequate training, and (iv) poorly defined responsibilities. These problems must be resolved at various levels: local, regional and national. PMID:20104279

    L'INAF-OA Cagliari (OACa) sta sviluppando un ricevitore criogenico a basso rumore basato su un mixer SSB (Single Side Band) a superconduttore SIS (Superconductor-Insulator-Superconductor) per la banda 3 mm. Il ricevitore, acquistato da IRAM, è stato fortemente modificato per essere adattato al fuoco Gregoriano di SRT (Sardinia Radio Telescope). Lo strumento è caratterizzato da una nuova criogenia a ciclo chiuso 4 K (per evitare l'uso di elio liquido in antenna), da un nuovo oscillatore locale (di tipo ALMA Banda 3) e da un nuovo sistema di controllo e di monitoraggio basato su schede Raspberry ed Arduino sviluppato ad OACa. Verranno presentati i recenti sviluppi sul ricevitore, inclusi i risultati preliminari della misura della temperatura di rumore, che raggiunge un valore pari a Trec=66 K alla frequenza di 86 GHz, nonostante la criogenia non sia ancora ottimizzata. L'INAF-OACa è coinvolto nel progetto AETHRA (Advanced European Technologies for Heterodyne Receivers for Astronomy) nel quadro del programma Radionet/Horizon2020 per il quale sta contribuendo al WP1 (Work Package 1). Lo scopo del WP1 è di sviluppare e costruire un dimostratore di un array di ricevitori a doppia polarizzazione per la banda 3 mm basato su amplificatori criogenici a basso rumore (LNA) in tecnologia a semiconduttore MMIC. Nell'ambito del WP1 l'OACa ha in carico il progetto di un OrthomodeTransducer (OMT) in guida d'onda o in tecnologia planare per la banda 72-116 GHz che sia integrabile con amplificatori MMICs ed adatto all'integrazione in un array da installare nel piano focale di un radiotelescopio. Verranno presentati i design preliminari degli OMT per AETHRA, che sono basati su prototipi sviluppati in passato da OACa.

    Nel corso dell’ultimo decennio l’esplorazione planetaria ha potuto beneficiare dei dati prodotti dagli spettrometri ad immagine: grazie a questa nuova classe di strumenti, realizzati per l’osservazione in remoto di superfici ed atmosfere planetarie, è possibile acquisire dati iperspettrali con elevati poteri risolutivi spaziali e spettrali. Il principale vantaggio offerto dagli spettrometri ad immagine, rispetto alle camere ed agli spettrometri puntuali, è rappresentato dalla capacità di misurare, identificare e mappare le unità composizionali delle superfici planetarie; queste informazioni permettono di investigare sia l’evoluzione geochimica delle superfici sia la dinamica e la composizione delle atmosfere. Sebbene i primi spettrometri ad immagine siano stati francesi (Phobos/ISM, Imaging Spectrometer for Mars) e statunitensi (Galileo/NIMS, Near Infrared Mapping Spectrometer), il nostro paese nel corso degli ultimi anni è stato in grado di proporre alla com unità spaziale internazionale degli strumenti dalle elevate prestazioni che sono stati infatti accettati come payload scientifici su diverse missioni interplanetarie: dai canali visibili di VIMS (Visual and Infrared Mapping Spectrometer) su Cassini (Nasa, JPL, ESA, ASI) e di OMEGA (Observatoire pour la Minéralogie, l’Eau, les Glacies et l’Activitè de Mars) su MarsExpress (ESA) ai due VIRTIS (Visible and Infrared Thermal Imaging Spectrometer) su Rosetta (ESA) e VenusExpress (ESA) fino a VIR-MS (Visible and Infrared Mapping Spectrometer) su Dawn (Nasa). In questo momento inoltre altri due spettrometri sono in avanzata fase di studio: JIRAM (Jovian InfraRed Auroral Mapper) su Juno (missione New Discovery Nasa) e VIHI (Visible and Infrared Hyperspectral Imager) integrato nel payload italiano di remote sensing SIMBIO-SYS di BepiColombo (missione cornerstone ESA).

    As the main oases developed in the arid regions of Central Asia, the region of Samarkand is the outcome of large hydraulic works carried out since the past times. The main result of such a great landscape transformation is a complex irrigation network formed by several artificial channels and useful for both urban water supply and irrigation purposes. Within the framework of the Italo-Uzbek Archaeological Project begun in 2001, a specific study was aimed to reconstruct the history of Dargom, the primary canal on the South of the city, and its relationships with the settlement dynamics. According to the most accepted theories, the Dargom was dug during the Achaemenid Age (6th-4th c. BC) as a consequence of a master plan linked to a strong central political power. The new investigations carried out by a joined team of Archaelogists and Geologists from the University Bologna allowed a new hypothesis on the way of digging and the chronology of the Dargom itself. The analyses on the historical settlement patterns seem to suggest a low development of Samarkand's territory during the Achaemenid times, whilst the increasing of sites during the Early Middle Age (5th-8th c.) can be explained throughout the rich trades along the Silk Road as well as the development of irrigated agriculture. The present-day Dargom is a high sinuosity channel deeply incised into the bedrock flowing to the east, strongly resembling a natural channel. It has been excavated for around 70 km along an apron of alluvial fans sourced by a southern mountain range. Its morphology clearly document a natural evolution after excavation: incision and meandering took place, likely due to the increasing gradient related to the headward migration of lowering of the base-level and the decrease of the bed load through time. Field survey around the fortress of Kafir Kala, the main archeological site geographically linked to the Dargom, allowed reconstructing the original bed of the canal, marked by a layer of

    The famous violin virtuoso Nicolò Paganini (born on 27 October 1782 in Genoa, died on 27 May 1840 in Nice) left us with many puzzles. An interesting aspect is his hair: In the 19th century, hair given away as a token of friendship or romantic love became very popular, and Paganini also seems to have made use of this fad. In 2009, a lock of hair, purportedly that of Paganini, kept in a locked presentation box together with a bilingual autograph inscription saying: "Alla Signora Chatterton avec les compliments de Nicolò Paganini" was bought at an auction. From this hair lock a sample was taken and was investigated morphologically by using digital light microscopy (digital microscope VHX-100, Keyence) in reflected and transmitted light with and without polarization at different magnifications up to 1:5,000. The sample was then compared with a hair sample from the possession of the Paganini family, which had been microscopically examined in 2012 by the co-author of this paper yielding numerous figures with measurement results that had been stored and could be retrieved for direct comparison. The hair sample consisted of ten strands of hair or hair fragments and was investigated with great effort for the following parameters: exogenous hair damage, especially feeding traces caused by parasites, modeling and angulation of hairs, hair thickness, medulla and pigmentation, curling and mercury load on the trace material. After evaluation of all findings not only a non-exclusion of identity can be determined, but due to the broad match of also rare findings there is no reasonable doubt about their identity. In addition, the findings suggest that the studied hair samples are in fact from Paganini's head. The present case of Nicolò Paganini's hair lock is also an excellent starting point for reflections on the probative value of trace hair investigations. This point is also critically discussed in the paper. Finally, this study shows that said lock of hair had probably

    Simple Summary This paper examines the trend of Italian academic faculties in complying with the obligation to inform university students of their right to exercise their conscientious objection to scientific or educational activities involving animals, hereafter written as “animal CO”, as established by Law 413/1993, “Norme sull’obiezione di coscienza alla sperimentazione animale” (“Rules on conscientious objection to animal experimentation”), thereafter “Law 413/1993”. Despite an increasing interest in the principles of animal ethics by the international community, this law is still largely disregarded more than 20 years after its enactment. The Ethics Committees, Animal Welfare Committees, as well as the Italian Ministry of Education, University and Research should preside over and monitor the Universities’ compliance with the duty to disclose animal CO. Abstract In Italy, Law 413/1993 states that public and private Italian Institutions, including academic faculties, are obliged to fully inform workers and students about their right to conscientious objection to scientific or educational activities involving animals, hereafter written as “animal CO”. However, little monitoring on the faculties’ compliance with this law has been performed either by the government or other institutional bodies. Based on this premise, the authors have critically reviewed the existing data and compared them with those emerging from their own investigation to discuss limitations and inconsistencies. The results of this investigation revealed that less than half of Italian academic faculties comply with their duty to inform on animal CO. Non-compliance may substantially affect the right of students to make ethical choices in the field of animal ethics and undermines the fundamental right to express their own freedom of thought. The Italian Ministry of Education, Universities and Research, ethics committees and animal welfare bodies should cooperate to make

    Historical research has shown that Terracina (Latina, Latium) played a fundamental role in the maritime and land traffic since before the foundation of the colony. The settlement was established where the organized system of maritime, land, coastal, and fluvial transport had the most ideal conditions to constitute an important commercial crossroads, apparently since the beginning of recorded history. In order to reconstruction the buried archaeological structures attributed to the ancient Roman port, traditionally attributed to Traiano, in the current area of the harbour of Terracina, it was carried out a gravity survey, more than 380 gravity stations. This method enables to recognize the cavity and the structures of the buildings underground through the results of variations density in the subsoil. In the residual gravity anomaly map a series of positive anomalies are visible which confirm the round structures and the pier of the buried foundations of the Imperial harbour. Unfortunately, little remains of the functioning facilities of the harbour's activities. The modern construction of the harbour, in fact, has to be developed around the new inhabitable commercial area, know today as Terracina Bassa or Borgo alla Marina. It had to be developed with a modern infrastructure of a harbor area, as in the construction of the rooms for storage of goods, warehouses, as well as for the thermal baths, hotels and amphitheatre. Furthermore, there are always the positive anomalies that characterize the area to the north-east of "Montone" hill where archaeological remains are easily visible near Via Lungolinea Pio VI. A large negative anomaly is situated in correspondence with "Montone". Gravity information shows an average density of the hill approximately 1.10 g/cm3, notably less than the recorded data relative to dry sand, approximately 1.6 g/cm3. The low value founds hits at the possibility of an "emptiness" in the subsoil of "Montone" hill, attribuiting to the possible

    RNAs have diverse structures that are important for biological function. These structures include bulges and internal loops that can form tertiary contacts or serve as ligand binding sites. The most commonly exploited RNA drug target for small molecule intervention is the bacterial ribosome, more specifically the ribosomal RNA aminoacyl-tRNA site (rRNA A-site) which is a major target for the aminoglycoside class of antibiotics. The bacterial A-site is composed of a 1×1 nucleotide all-U internal loop and a 2×1 nucleotide all-A internal loop separated by a single GC base pair. Therefore, we probed the molecular recognition of a small library of four aminoglycosides for binding a 16384-member bacterial rRNA A-site-like internal loop library using Two-Dimensional Combinatorial Screening (2DCS). 2DCS is a microarray-based method that probes RNA and chemical spaces simultaneously. These studies sought to determine if aminoglycosides select their therapeutic target if given a choice of binding all possible internal loops derived from an A-site-like library. Results show that the bacterial rRNA A-site was not selected by any aminoglycoside. Analyses of selected sequences using the RNA Privileged Space Predictor (RNA-PSP) program show that each aminoglycoside preferentially binds different types of internal loops. For three of the aminoglycosides, 6″-azido-kanamycin A, 5-O-(2-azidoethyl) neamine, and 6″-azido-tobramycin, the selected internal loops bind with ~10-fold higher affinity than the bacterial rRNA A-site. The internal loops selected to bind 5″-azido-neomycin B bind with similar affinity as the therapeutic target. Selected internal loops that are unique for each aminoglycoside have dissociation constants ranging from 25 to 270 nM and are specific for the aminoglycoside they were selected to bind compared to the other arrayed aminoglycosides. These studies further establish a database of RNA motifs that are recognized by small molecules that could be used to

    The Sputnik IV launch occurred on May 15, 1960. On May 19, an attempt to deorbit a 'space cabin' failed and the cabin went into a higher orbit. The orbit of the cabin was monitored and Moonwatch volunteer satellite tracking teams were alerted to watch for the vehicle demise. On September 5, 1962, several team members from Milwaukee, Wisconsin made observations starting at 4:49 a.m. of a fireball following the predicted orbit of Sputnik IV. Requests went out to report any objects found under the fireball path. An early morning police patrol in Manitowoc had noticed a metal object on a street and had moved it to the curb. Later the officers recovered the object and had it dropped off at the Milwaukee Journal. The Moonwarch team got the object and reported the situation to Moonwatch Headquarters at the Smithsonian Astrophysical Observatory. A team member flew to Cambridge with the object. It was a solid, 9.49 kg piece of steel with a slag-like layer attached to it. Subsequent analyses showed that it contained radioactive nuclei produced by cosmic ray exposure in space. The scientists at the Observatory quickly recognized that measurements of its induced radioactivity could serve as a calibration for similar measurements of recently fallen nickel-iron meteorites. Concurrently, the Observatory directorate informed government agencies that a fragment from Sputnik IV had been recovered. Coincidently, a debate in the UN Committee on Peaceful Uses of Outer Space involved the issue of liability for damage caused by falling satellite fragments. On September 12, the Observatory delivered the bulk of the fragment to the US Delegation to the UN. Two days later, the fragment was used by US Ambassador Francis Plimpton as an exhibit that the time had come to agree on liability for damage from satellite debris. He offered the Sputnik IV fragment to USSR Ambassador P.D. Morozov, who refused the offer. On October 23, Drs. Alla Massevitch and E.K. Federov of the USSR visited the

    Cyclic sedimentation and lateral facies changes make coal bed correlations inconclusive and difficult. This uncertainty can be further complicated if a coal basin has been structurally deformed. Coal macerals can be studied to indicate the nature and degree of coalification. Their use in coal bed correlation, however, is limited. Most of the trace elements and their ratios that have been studied show significant within-bed lateral and stratigraphic variations, and thus are not effective in correlating coal beds regionally. Geochemically coherent groups of elements, such as rare earth elements (REE) and platinum group elements (PGE), appear to be highly differentiated in coal-forming environments. Geochemical coherent elemental triads appear to be useful for coal bed identification or fingerprinting. The best triad which was demonstrated to be effective in coal bed characterization in western Kentucky, is that of Al, La and Sc. These three elements are highly correlated with one another and they can be determined accurately and simultaneously with instrumental neutron activation analysis (INAA). The elemental triad Al-La-Sc is used to identify and fingerprint three key coal beds in western Kentucky: the Springfield (western Kentucky No. 9), the Davis (western Kentucky No. 6), and the Mining City and Dawson Springs are both considered to be the No. 4 coal bed in western Kentucky). Four distinct groupings can be recognized by use of the Al-La-Sc triad. The Dawson Springs coals have the highest Al/(La + Sc) ratios, followed by the Springfield, the Davis and the Mining City. The Mining City coal bed generally has the highest La/Sc ratio. However, the Dawson Springs is not correlated with the Mining City using the triad analysis, even though they have reportedly similar stratigraphic positions in the western Kentucky coal basin. The Al-La-Sc triad appears to be effective in discriminating between the Springfield and the Davis coal beds throughout the entire Illinois

    that is minimized during the variational assimilation procedure.Results show that more significant improvements are obtained in floods events than in false alarms. For instance, error on peak flow reduces respectively of about 30% and 20% (lead time of nearly 20 hours) at the measurement station that is representative of river network outlet (S. Giovanni alla Vena).The best performances correspond to single peak flood events, while in some more complex cases DA does not significantly improve modeled discharges, possibly because of shortcomings in model structure.Forecasts at downstream locations enhance especially when peak flow of the main upstream tributaries is included in the assimilation window. In conclusion, the operational hydrologic forecasting chain can effectively benefits from the developed assimilation system, although in the limit of the model structure.

    training dataset of occurrences and a test dataset, a cross validation is made. The valuation both for flows and slides was performed through Prediction Rate Curves (PRC). By utilising the occurrences of the test dataset, PRC derived from the relation between CF trend in the whole area (cumulative percentage), portion of total area and number of landslides. As result, engineering geology can be indicated as the dominant factor for PRC of flows; likewise engineering geology, land use and RBS combination is the more effective combination. On the other side, slope and aspect resulted less determinative in best PRC trend. Moreover, the combination of engineering geology and slope allowed the computation of best PRC for landslide.

    The Veneto Volcanic Province (VVP), in the North-East of Italy represents one of the most important magmatic province of the Adria Plate. VVP magmatism occurred in a period ranging from late Paleocene to late Oligocene (De Vecchi et al., 1976). Five main volcanic districts can be defined from north-west to south-east: Val d'Adige, Marosticano, Lessini Hills, Berici Hills and Euganean Hills. Most of the volcanic products are relatively undifferentiated lavas, ranging in compostion from mela-nephelinites to quartz-normative tholeiites (Beccaluva et al., 2007). By contrast in the Euganean Hills volcanic and subvolcanic rocks range from subordinate basalts to prevalently acidic types, mostly quartz-trachytes and rhyolites (Milani et al., 1999). Despite of the deep petrological knowledge about this province, the radioisotopic ages of the related volcanic activities for each district are still poorly defined or even totally missing. 40Ar/39Ar ages on 9 samples have been obtained to determine the age range for the VVP. 40Ar/39Ar whole rock step heating analyses yielded ages ranging from 40.7 ± 0.2 Ma to 23.3 ± 1.5 Ma for basanites of Val d'Adige and Marosticano area, respectively. For the Lessinean district, 40Ar/39Ar whole rock analyses for two basanites, one trachybasalt and one alkali basalt close to 40 Ma, while a tholeiite from the same area yielded the youngest age for this district (i.e. 32.9 ± 1.8 Ma). This young age is comparable to 40Ar/39Ar ages obtained for the Euganean Hills intermediate-acidic rocks (Jourdan, pers. comm., 2016), suggesting a time-related shift from more alkaline to Si-saturated magmatism in the whole province.

    2011-05-01

    On March 15th 2010, Italy adopted the Law no. 38 "Disposizioni per garantire l'accesso alle cure palliative e alla terapia del dolore" (Provisions aimed at ensuring access to palliative care and pain therapy). The aim of pain therapy is to enable patients with chronic diseases to achieve pain control. Palliative care, as defined by the World Health Organization, aims at "improving the quality of life of patients and families, who face the problems associated with incurable diseases, through prevention and relief from suffering, achieved through an early identification and treatment of pain by pharmacological medication and other physical, psychosocial and spiritual techniques". The main issues addressed by the law concern the monitoring of pain (the doctors will have to record on the clinical report form every level of pain intensity suffered by the patient, the appropriate therapy administered, and the pain relief achieved. This report must be kept accurately in all settings: hospital, day hospital and in outpatients). The law also suggests the establishment of two kinds of regional networks. One network (including Hospices) ensures the administration of palliative care to terminally ill patients; the other, including clinics and centers of pain therapy, provides assistance to patients with chronic pain. These networks involve general practitioners, hospital specialists and pain therapy specialists in order to ensure the best patient care. Simplification of the prescription of opiate drugs is also included in the law. In the prescription of opiates, the National Health Service medical staff can use the normal prescription form, and opiates will reimbursed by the NHS, like all other drugs. In addition, the technical papers provide precise indications of the appropriate modality of administration. The law allocates (art. 12, paragraph 2) 100 million euros per year and € 2,450,000 in the biennium 2010-2011 to implement experimental regional projects: "hospital

    much of the lower Ouarzazate Supergroup volcanic rocks in the area are probably related to caldera out-flow facies and collapse. Late stage PA3 intrusive rocks include the Bouskour–Sidi Flah and Timijt rhyolitic dike swarms at about 563 Ma, the voluminous pink Isk-n-Alla granite (559 ± 5 Ma), and volumetrically minor gabbro of Tagmout (556 ± 5 Ma). Rhyolite flows from the upper part of the Ouarzazate Supergroup, above a regional angular unconformity, yielded ages of 558 ± 4 and 556 ± 4 Ma. The youngest ages place an upper limit on block faulting and weak folding during latest Pan-African tectonic activity (PA3), coincident with the departure of the Cadomian crustal fragment from the northern margin of the WAC.

  20. The ancient harbour system of Terracina (Latium, Italy) obtained by gravity and seismic surveys.

    Historical research has shown that Terracina (Latina, Latium) played a fundamental role in the maritime and land traffic since before the foundation of the colony. The settlement was established where the organized system of maritime, land, coastal, and fluvial transport had the most ideal conditions to constitute an important commercial crossroads, apparently since the beginning of recorded history. In order to reconstruction the buried archaeological structures attributed to the ancient Roman port, traditionally attributed to Traiano, in the current area of the harbour of Terracina, it was carried out a gravity survey, more than 380 gravity stations. The gravity method enables to recognize the cavity and the structures of the buildings underground through the results of variations density in the subsoil. Seismic tomography treats the problem of identifying a buried structure as a wave propagation process by inverting the linearized wave equation to compute the spatial distribution of the slowness of the velocity. The purpose of our tomographic study is to further test the method and to guide archaeologists in their future excavations by locating and identifying buried structures. In the residual gravity anomaly map a series of positive anomalies are visible which confirm the round structures and the pier of the buried foundations of the Imperial harbour. Unfortunately, little remains of the functioning facilities of the harbour's activities. The modern construction of the harbour, in fact, has to be developed around the new inhabitable commercial area, know today as Terracina Bassa or Borgo alla Marina. It had to be developed with a modern infrastructure of a harbor area, as in the construction of the rooms for storage of goods, warehouses, as well as for the thermal baths, hotels and amphitheatre. Furthermore, there are always the positive anomalies that characterize the area to the north-east of "Montone" hill where archaeological remains are easily visible

    OBIETTIVI: valutare lo stato di salute della popolazione residente nel comune di Manfredonia dal 1970 al 2013. DISEGNO: analisi descrittiva dell'andamento temporale della mortalità generale, per gruppi di cause, dal 1970 al 2013. SETTING E PARTECIPANTI: i dati di mortalità e le popolazioni residenti sono di fonte Istat. Sono state esaminate 55 cause di decesso. Le analisi sono disaggregate per sesso e periodo. PRINCIPALI MISURE DI OUTCOME: sono stati elaborati i rapporti standardizzati di mortalità (SMR%), con i rispettivi intervalli di confidenza al 90% (IC90%), e i tassi di mortalità standardizzati col metodo diretto (TSD ). RISULTATI: lo stato di salute misurato dal tasso di mortalità per tutte le cause migliora nel tempo: i TSD passano da 92 x10.000 negli anni 1970-1974 a 52 x10.000 nel biennio 2012-2013 negli uomini, da 70 x10.000 a 39 x10.000 nelle donne. Tuttavia, rispetto alla media regionale Manfredonia perde progressivamente il suo vantaggio, passando da -20% a -10% negli uomini, e da -20% a +1,5% nelle donne. Questo andamento è molto evidente per il complesso delle cause cardiovascolari, mentre i tumori maligni sono in generale nella media regionale. Nell'ultimo periodo disponibile per causa di decesso (2006-2011), la mortalità per infarto miocardico è stata più alta della media regionale (uomini: +35%; donne: +54%). I rapporti standardizzati di mortalità (SMR) mostrano tra gli uomini valori in crescita, in particolar modo rispetto al riferimento provinciale, con un eccesso a cominciare dal periodo 2006-2011 (22 decessi/anno e 19 attesi; SMR%: 117,2; IC90% 101,1-135,2; riferimento: provincia di Foggia). Anche tra le donne gli SMR% superano i riferimenti provinciali negli ultimi periodi esaminati (nel 2012-2013: 7 decessi/ anno e 4,2 attesi; SMR%: 116,4; IC90% 97,0-260,7; riferimento: provincia di Foggia). CONCLUSIONI: la mortalità a Manfredonia è diminuita in misura minore rispetto a quella osservata nei riferimenti provinciali e regionali

    the quantum level leads naturally to the issue of entanglement. This is an exclusive feature of the quantum world, which represents a valuable resource for quantum information processing and for high-precision measurements. The de.nition and criteria for measuring entanglement have been traditionally formulated within the Hilbert-space formalism (the quantum state formalism). However, quantum structures are intrinsically multi-mode systems, for which the Hilbert-space approach is often unpractical and cumbersome. More appealing are the "classical looking" phase space descriptions, where it is hence of great importance to reformulate concepts such as entanglement or Bell inequalities. The paper by Santos addresses the general problem of characterizing the entanglement properties of an electromagnetic field in the language of Q-representation. Entanglement involving the spatial modes of the electromagnetic field carrying orbital angular momentum provides new degrees of freedom and could play an important role in the field of quantum information, since such non-classical states enable the possibility of multichannel communications. The paper by Barbosa discusses quantum states of twin photons produced by parametric down-conversion and entangled in polarization and orbital angular momentum. The issue of entanglement is intrinsically connected to decoherence, and to the transition from the quantum to the classical world. In particular, massive systems are characterized by strong interactions with the environment, and at room temperature they usually exhibit classical behaviour. In this context, the paper by Karlsson discusses the decay of quantum correlations of protons and positive muons in condensed matter, a system characterized by strong coupling to the environment, and proposes experiments where such quantum correlations could be measured. Mancini et al. investigate macroscopic manifestations of quantum features, presenting a proposal for entangling the macroscopic

Which self-report symptom scales or checklists are psychometrically sound for clinical use to assess sport-related concussion? Articles available in full text, published from the establishment of each database through December 2008, were identified from PubMed, Medline, CINAHL, Scopus, Web of Science, SPORTDiscus, PsycINFO, and AMED. Search terms included brain concussion, signs or symptoms, and athletic injuries, in combination with the AND Boolean operator, and were limited to studies published in English. The authors also hand searched the reference lists of retrieved articles. Additional searches of books, conference proceedings, theses, and Web sites of commercial scales were done to provide additional information about the psychometric properties and development for those scales when needed in articles meeting the inclusion criteria. Articles were included if they identified all the items on the scale and the article was either an original research report describing the use of scales in the evaluation of concussion symptoms or a review article that discussed the use or development of concussion symptom scales. Only articles published in English and available in full text were included. From each study, the following information was extracted by the primary author using a standardized protocol: study design, publication year, participant characteristics, reliability of the scale, and details of the scale or checklist, including name, number of items, time of measurement, format, mode of report, data analysis, scoring, and psychometric properties.

    value -referring to biodiversity, geodiversity, culture- which can be considered as a special heritage. Starting from the concept of Geomorphosite, a geomorphologic landform with a scientific, cultural and socio-economical value (Panizza 2001), we propose a further definition, useful in the preliminary steps of the landscape analysis: "geomorpho-landscape" as a spatial object or component of a geological landscape, whose geo-morphological evolution, linked to the geological setting, are elements of aesthetical, semiological as well as historical and cultural value. The structure of the landscape is represented by the physical shape and spatial organization, in dynamic way: it is necessary to provide a readout of the landscape components that supplements the geo-morphological, lithological, geodiversity data (Lugeri et alii, 2012). The concept of "geomorpho-landscape" is conceived to address the need to describe by a synthetic approach the geological processes emerging at the landscape scale, allowing to link spatial patterns to geological processes Each geo-form has in itself geological, geo-morphological, landmark, historical and cultural features, of such special relevance, that they can be defined in terms of scientific quality, rarity, aesthetic appeal and educational and cultural value.

    considered as a sort of pseudo-stratigraphy, since they are the oldest feature that can be traced continuously at the map scale. For this reason we have developed a set of attributes identifying the tectonic and lithological units (a "legend"), implemented both in the GIS database and in the 3D models, which at the same time is compatible with the data structure of 3D modelling packages like Move and Skua/Gocad, and allows tracing the complex hierarchic classification of the units mapped in the GIS. This allows for the almost automatic and consistent two-way transfer of data between the GIS and geomodelling environments. E.g. results of 3D modelling, which is based on input data originally stored in the GIS, will eventually be transferred back to the GIS. The results of this study, which are preliminarily presented here, will open new opportunities to study the collision- and subduction-related nappe architecture and kinematics with younger deformations removed, and will eventually lead (with additional studies) to a step-by-step retrodeformation supported by modern technologies, following the path traced by Argand at the beginning of the 20th century.

    bundle can simultaneously observe a continuous sky area measuring no less than 56 x 56 arcsec 2. A dedicated machine, the Mask Manufacturing Unit (MMU) , cuts the slits for the entrance apertures of the spectrograph. The laser is capable of cutting 200 slits in less than 15 minutes. This facility was put into operation at Paranal by the VIRMOS Consortium already in August 2000 and has since been extensively used for observations with the FORS2 instrument; more details are available in ESO PR 19/99.

PR Photo 09e/02 : The spiral galaxy NGC 5364 was the first object to be observed by VIMOS. This false-colour near-infrared, raw "First Light" photo shows the extensive spiral arms. Technical information about this photo is available below. VIMOS was shipped from Observatoire de Haute-Provence (France) at the end of 2001, and reassembled at Paranal during a first period in January 2002. From mid-February, the instrument was made ready for installation on the VLT MELIPAL telescope; this happened on February 24, 2002. VIMOS saw "First Light" just two days later, on February 26, 2000, cf. PR Photo 09e/02 . During the same night, a number of excellent images were obtained of various objects, demonstrating the fine capabilities of the instrument in the "direct imaging"-mode. The first spectra were successfully taken during the night of March 2 - 3, 2002 . The slit

    Editors Note:This week were at the 227th AAS Meeting in Kissimmee, FL. Along with several fellow authors from astrobites.com, I will bewritingupdates on selectedevents at themeeting and posting at the end of each day. Follow along here or at astrobites.com, or catch ourlive-tweeted updates from the @astrobites Twitter account. The usual posting schedule for AAS Nova will resumenext week.Things kicked off last night at our undergraduate reception booth. Thanks to all of you who stopped by we were delightedto have so many people tell us that they already know about and useastrobites, and we were excited to introduce a new cohort of students at AAS to astrobites for the first time.Tuesday morning was the official start of the meeting. Here are just a few of the talks and workshops astrobiters attended today.Opening Address (by Becky Smethurst)The President of the AAS, aka our fearless leader Meg Urry kicked off the meeting this morning at the purely coffee powered hour of 8am this morning. She spoke about the importance of young astronomers at the meeting (heres looking at you reader!) and also the importance of the new Working Group for Accessibility and Disabilities (aka WGAD pronounced like wicked) at the AAS. The Society has made extra effort this year to make the conference accessible to all,a message which was very well received by everyone in attendance.Kavli Lecture: New Horizons Alan Stern (by Becky Smethurst)We were definitely spoilt with the first Plenary lecture at this years conference Alan Stern gave us a a review of the New Horizons mission of the Pluto Fly By (astrobites covered the mission back in July with this post). We were treated to beautiful images, wonderful results and a foray into geology.Before (Hubble) and after #NewHorizons. #thatisall #science #astro alanstern #aas227 pic.twitter.com/kkMt6RsSIR Science News (@topsciencething) January 5, 2016Some awesome facts from the lecture that blew my mind:New Horizons is now 2AU (!) beyond Pluto
