Verifying entanglement in the Hong-Ou-Mandel dip  

SciTech Connect

The Hong-Ou-Mandel interference dip is caused by an entangled state, a delocalized biphoton state. We propose a method of detecting this entanglement by utilizing inverse Hong-Ou-Mandel interference, while taking into account vacuum and multiphoton contaminations, phase noise, and other imperfections. The method uses just linear optics and photodetectors, and for single-mode photodetectors we find a lower bound on the amount of entanglement.

Eielson Air Force Base OU-1 baseline risk assessment  

SciTech Connect

This Baseline Risk Assessment report is the second volume in a set of three volumes for operable Unit 1 (OU-1). The companion documents contain the Remedial Investigation and the Feasibility Study. Operable Unit 1 (OU-1) is one of several groups of hazardous waste sites located at Eielson Air Force Base (AFB) near Fairbanks, Alaska. The operable units at Eielson are typically characterized by petroleum, oil, lubricant/solvent contamination, and by the presence of organics floating at the water table. In 1989 and 1990, firms under contract to the Air Force conducted field studies to gather information about the extent of chemical contamination in soil, groundwater, and soil air pore space (soil gas) at the site. This report documents the results of a baseline risk assessment, which uses the 1989 and 1991 site characterization database to quantify the potential human health risk associated with past Base industrial activities in the vicinity of OU-1. Background data collected in 1992 were also used in the preparation of this report.

Electronic Hong-Ou-Mandel interferometer for multimode entanglement detection  

NASA Astrophysics Data System (ADS)

We show that multimode entanglement of electrons in a mesoscopic conductor can be detected by a measurement of the zero-frequency current correlations in an electronic Hong-Ou-Mandel interferometer. By this means, one can further establish a lower bound to the entanglement of formation of two-electron input states. Our results extend the work of Burkard and Loss [Phys. Rev. Lett. 91, 087903 (2003)] to many channels and provide a way to test the existence of entangled states involving both orbital and spin degrees of freedom.

Hong Ou Mandel interferometer: A quantum measurement tool  

NASA Astrophysics Data System (ADS)

Quantum computing research has been around for several decades, since it was first proposed by Richard Feynman. Many efforts have been made to utilize quantum systems in creation of new computing devices in the recent years. One of the essential tools used for characterization and manipulation of optical quantum systems is a Hong Ou Mandel (HOM) Interferometer. It is used in this work to provide information about propagation, distortion and degree of indistinguishability of single photons. This work provides complete characterization of an optical tunneling effect in dielectric Bragg gratings. Samples with different thin film configurations are examined and their corresponding propagation delay times are calculated with sub-femtosecond precision. It is determined that for specific configurations for dielectric stacks, propagation delays can exhibit superluminal behavior. The distortion due to this effect is also calculated using HOM profiles. HOM interferometer is also used to calculate the degree of coalescence between two dissimilar sources. Single photons generated by quantum dot emission and parametric down conversion are tailored through aggressive filtering techniques to be identical in their spectral, temporal and polarization profiles. The degree of their coalescence is then calculated in an attempt to create quantum interference. This work attempts to provide better understanding of single photon interactions through use of an HOM interferometer.

Signatures of Hong-Ou-Mandel interference at microwave frequencies  

NASA Astrophysics Data System (ADS)

Two-photon quantum interference at a beam splitter, commonly known as Hong-Ou-Mandel interference, is a fundamental demonstration of the quantum mechanical nature of electromagnetic fields and a key component of various quantum information processing protocols. The phenomenon was recently demonstrated with microwave-frequency photons by Lang et al (2013 Nature Phys. 9 345-8). This experiment employed circuit QED systems as sources of microwave photons, and was based on the measurement of second-order cross-correlation and auto-correlation functions of the microwave fields at the outputs of the beam splitter using linear detectors. Here we present the calculation of these correlation functions for the cases of inputs corresponding to: (i) trains of pulsed Gaussian or Lorentzian single microwave photons and (ii) resonant fluorescent microwave fields from continuously driven circuit QED systems. In both cases, the signature of two-photon quantum interference is a suppression of the second-order cross-correlation function for small delays. The experiment described in Lang et al (2013) was performed with trains of Lorentzian single photons, and very good agreement with experimental data is obtained. The results are relevant not only to interference experiments using circuit QED systems, but any such setup with highly controllable sources and time-resolved detection.

Dynamique sédimentaire comparative dans les bassins stéphano-permiens des Ida Ou Zal et Ida Ou Ziki, haut Atlas Occidental, MarocDynamic sedimentology of two Upper Stephano-Lower Permian basins: Ida Ou Zal and Ida Ou Ziki, western High Atlas, Morocco  

NASA Astrophysics Data System (ADS)

The intra-mountainous Ida Ou Zal Basin developed as a graben during the Stephanian (Carboniferous) and Lower Permian. Along its borders from east to west are the remnants of basal conglomerates. Passing laterally towards the centre of the basin are fine-grained fluvial-lacustrine sediments or flood-plain deposits. The important accumulation (1800 m) of sediments, associated with climatic and tectonic changes, caused substantial subsidence in a late orogenic setting. The remnants of sporadic volcanic products (shards) found in the Ida Ou Zal and the Ida Ou Zika Basins suggest nearby simultaneous magmatic activity. A comparison between the basins of Ida Ou Zal and Ida Ou Ziki suggest that the two basins formed a single unit, called the Souss Basin, ultimately terminated between the Lower Permian and Upper Permian times by a sinistral movement of the N70-80° Agadir Ou Anzizen Fault (west branch of the Tizi N'Test Fault) at the very end of the Hercynian Orogeny in Morocco.

However, the emf method, which is highly accurate near the stoichiometric composition, is applicable only for homogeneous UO{sub 2-x}. The useful range of the emf method can be expanded for analyzing substoichiometric UO{sub 2}.

Spatial and temporal variation of the water quality of an intermittent river - Oued Fez (Morrocco)  

NASA Astrophysics Data System (ADS)

In the South of the Mediterranean basin, many rivers are characterized by an alternation of very long dry periods only cut by short flood events. Currently, the socio-economical development of these zones is limited by the water scarcity but also by the poor quality of the water resources. In fact, human activities, generally concentrated in overpopulated cities, generate large quantity of domestic and industrial effluents which are directly rejected in the environment without any treatment. In Morocco, the well known city of Fez illustrates perfectly this situation observed in all the Maghreb countries. During the dry period, the Oued Fez which crosses the city, is only fed by non-treated anthropogenic inputs. Accumulation of pollutants is observed in the river bed sediments. Domestic and industrial effluents (200 000 m3/day) pollute all the down stream water bodies some of which are used for irrigation and other for fresh water supply. During floods, mainly generated by urban runoff, river bed sediments could be remobilized and a significant flush effect could occur. This study aims at characterising and quantifying the pollutant concentrations and fluxes in various points of the Oued Fez hydrological network and assessing its impact on the Sebou River; water resources of this river being considered as national priority in Morocco. Due to the peculiar Mediterranean hydrological regime, specific observation networks are set up to assess the temporal and spatial variability of pollutant fluxes in the river and to rank water and pollutant sources. The sampling sites on the Fez and Sebou oueds are selected based these criteria. A reference station is chosen upstream of the Oued Fez less than 300 metres from the direct anthropic inputs. Water quality is evaluated through nutrients (Total nitrogen, and total phosphorus essentially), heavy metals (essentially chromium) and suspended solids. The results of 4 sampling campaigns indicate that: in terms of nitrogen, phosphorus and chromium, the pollution levels are high (> 60 mg/l N, > 10mg/l P, > 0,5mg/l Cr, respectively) at the most polluted sites. The nitrogen, phosphorus and chromium fluxes, in steady state conditions, show that more than 500 kg/hour of nitrogen, 60 kg/hour of phosphorus and 2,5 kg/hour of chromium are flushed by the Oued Sebou downstream of its confluence with the Oued Fez. In spite of the high flux values, a significant fraction of the particulate form of studied pollutants are stored in the riverbed sediments, and can be remobilized by the urban flash floods which occur after each rainfall event.

Caracterisation des proprietes acoustiques des materiaux poreux a cellules ouvertes et a matrice rigide ou souple  

NASA Astrophysics Data System (ADS)

L'objectif global vise par les travaux de cette these est d'ameliorer la caracterisation des proprietes macroscopiques des materiaux poreux a structure rigide ou souple par des approches inverses et indirectes basees sur des mesures acoustiques faites en tube d'impedance. La precision des approches inverses et indirectes utilisees aujourd'hui est principalement limitee par la qualite des mesures acoustiques obtenues en tube d'impedance. En consequence, cette these se penche sur quatre problemes qui aideront a l'atteinte de l'objectif global precite. Le premier probleme porte sur une caracterisation precise de la porosite ouverte des materiaux poreux. Cette propriete en est une de passage permettant de lier la mesure des proprietes dynamiques acoustiques d'un materiau poreux aux proprietes effectives de sa phase fluide decrite par les modeles semi-phenomenologiques. Le deuxieme probleme traite de l'hypothese de symetrie des materiaux poreux selon leur epaisseur ou un index et un critere sont proposes pour quantifier l'asymetrie d'un materiau. Cette hypothese est souvent source d'imprecision des methodes de caracterisation inverses et indirectes en tube d'impedance. Le critere d'asymetrie propose permet ainsi de s'assurer de l'applicabilite et de la precision de ces methodes pour un materiau donne. Le troisieme probleme vise a mieux comprendre le probleme de transmission sonore en tube d'impedance en presentant pour la premiere fois un developpement exact du probleme par decomposition d'ondes. Ce developpement permet d'etablir clairement les limites des nombreuses methodes existantes basees sur des tubes de transmission a 2, 3 ou 4 microphones. La meilleure comprehension de ce probleme de transmission est importante puisque c'est par ce type de mesures que des methodes permettent d'extraire successivement la matrice de transfert d'un materiau poreux et ses proprietes dynamiques intrinseques comme son impedance caracteristique et son nombre d'onde complexe. Enfin, le quatrieme probleme porte sur le developpement d'une nouvelle methode de transmission exacte a 3 microphones applicable a des materiaux ou systemes symetriques ou non. Dans le cas symetrique, on montre que cette approche permet une nette amelioration de la caracterisation des proprietes dynamiques intrinseques d'un materiau.

Proposal for demonstrating the Hong–Ou–Mandel effect with matter waves  

NASA Astrophysics Data System (ADS)

The Hong–Ou–Mandel effect is a demonstration of destructive quantum interference between pairs of indistinguishable bosons, realised so far only with massless photons. Here we propose an experiment to realize this effect in the matter-wave regime using pair-correlated atoms produced via a collision of two Bose–Einstein condensates and subjected to two laser-induced Bragg pulses. We formulate a measurement protocol for the multimode matter-wave field, which—unlike the typical two-mode optical case—bypasses the need for repeated measurements under different displacement settings of the beam splitter, markedly reducing the number of experimental runs required to map out the interference visibility. Although the protocol can be used in related matter-wave schemes, we focus on condensate collisions. By simulating the entire experiment, we predict a Hong–Ou–Mandel dip visibility of ~69%. This visibility highlights strong quantum correlations between the atoms, paving the way for a possible demonstration of a Bell inequality violation with massive particles in a related Rarity–Tapster setup.

Water quality assessment of a highly polluted Mediterranean River - Oued Fez (Morocco)  

NASA Astrophysics Data System (ADS)

In the South of the Mediterranean basin, many rivers are characterized by an alternation of very long dry periods only cut by short flood events. Currently, the socio-economical development of these zones is limited by water scarcity and poor quality of the water resources. Indeed human activities, generally concentrated in overpopulated cities, generate large quantity of domestic and industrial effluents which are directly rejected in the environment without any treatment. In Morocco, the well known city of Fez illustrates perfectly this situation, observed in most developing countries. The oued Fez receives continuously the non-treated domestic and industrial effluents (90.000 m3/day) of the city and pollutes all the downstream water bodies. Indeed, it is a tributary of the Sebou River, a major body of great economical importance used for irrigation and freshwater supply. This study aims at characterising and quantifying the pollutant concentrations and fluxes in various points of oued Fez's hydrological network and assessing its impact on the Sebou River; this river's preservation being considered a national priority in Morocco. A coupled water quality-water quantity monitoring scheme has been implemented on oued Fez since 2008. In addition to basic hydrological data, water quality samples are collected at regular intervals at 8 locations where discharge is simultaneously measured using an Acoustic Doppler Current Profiler (ADCP). Water samples are analysed for different forms of nitrogen (nitrates, nitrites, ammonium and total nitrogen), phosphorus (soluble reactive phosphorus and total phosphorus) but also total chromium which is used in the leather tanning processes, one of the most important industrial production of the city of Fez, using a photospectrometer (Hach Lange DR 2800 VIS-photometer (Germany). The results of 17 sampling campaigns, carried out over 3 hydrological years, indicate that the rural areas contribute mostly to baseflow during the wet period while non-treated anthropogenic inputs constitute most of the flow during the dry period. The pollution levels are very high as the mean values reach 39 mg/l N, 5 mg/l P, 0.2mg/l Cr, for total nitrogen, total phosphorus and total chromium respectively at the most polluted sites. Even if the hydrological conditions induce important concentration variations, the pollution levels remain high all along the year. The nitrogen, phosphorus and chromium fluxes calculated for steady state conditions, show that more than 500 kg/hour of nitrogen, 60 kg/hour of phosphorus and 2.5 kg/hour of chromium are flushed by the oued Sebou downstream of its confluence with the oued Fez. These fluxes are due to human activities and do not vary significantly with the hydrological conditions. This study shows that a relatively limited observation network allows the characterization of the temporal and spatial variability of the pollution levels if the monitoring points are selected by taking into account the main pollution sources and the specificity of the hydrological conditions.

Scalable Hong-Ou-Mandel manifolds in quantum-optical ring resonators  

NASA Astrophysics Data System (ADS)

Quantum information processing, from cryptography to computation, based upon linear quantum-optical circuit elements relies heavily on the ability offered by the Hong-Ou-Mandel (HOM) effect to "route" photons from separate input modes into one of two common output modes. Specifically, the HOM effect accomplishes the path entanglement of two photons at a time such that no coincidences are observed in the output modes of a system exhibiting the effect. In this paper, we prove, in principle, that by operating a specific nanophotonic device properly, one can conditionally "bunch" coincident input photons in a way that is more configurable than with an ordinary 50:50 beam splitter, while maintaining the inherent scalability of such an on-chip device.

Interactions between the hydrology and hydrochemistry of an intermittent southern Mediterranean River- Oued Fez (Morocco)  

NASA Astrophysics Data System (ADS)

Mediterranean catchments are often characterized by highly variable rainfall inputs and intermittent flows. In comparison to the existing knowledge on their hydrological behaviour, the interactions between flow conditions and pollution levels remain less documented. This study aims at filling that gap through a case study on Oued Fez (Morocco). Oued Fez is an intermittent river located in central-eastern Morocco. It has a 615 km2 catchment 10% of which corresponds to the city of Fez, the 3rd biggest in the kingdom (1.2 M inhabitants). Oued Fes is a tributary of the Sebou River, a major body of great economical importance used for irrigation and freshwater supply. A coupled water quality-water quantity monitoring scheme has been implemented on Oued Fez since 2008. In addition to basic hydrological data, water quality samples are collected at regular intervals at 8 locations where discharge is simultaneously measured using an Acoustic Doppler Current Profiler (ADCP). Water samples are analysed for different forms of nitrogen (nitrates, nitrites, ammonium and total nitrogen) and phosphorus (soluble reactive phosphorus and total phosphorus) using a photospectrometer (Hach Lange DR 2800 VIS-photometer (Germany). The results of the study indicate that, despite variations in annual rainfall, the catchment's hydrological response is controlled by the urban impervious zones during floods. The rural areas contribute mostly to baseflow during the wet period while non-treated anthropogenic inputs constitute most of the flow during the dry period. This in turn affects the water quality results. Indeed: - during low flow conditions the pollution levels are very high and total nitrogen and total phosphorus concentrations reach 45 mg/l N and 6.5 mg/l P respectively at the most polluted sites. - during average and high flow conditions the pollution levels decrease due to dilution. Total nitrogen and total phosphorus concentrations reach 32 mg/l N and 3.5 mg/l P respectively with minimum values lower than 20 mgN.L-1 and 2 mgP.L-1 during the flood of March 2010. The hydrological conditions also impact the distribution of the relative part of the different forms of nitrogen (NH4 and Norg) which varies significantly in time and clearly evolves with temperature. The NH4/Norg ratios vary between 0.25 in winter and 2 in summer because of ammonification processes. Despite of the variations in flow conditions, nitrogen and phosphorus fluxes remain quite stable at the sites directly influenced by waste water inputs (more than 500 kg/hour of nitrogen and 60 kg/hour of phosphorus). However, in low flow conditions, a significant fraction of the particulate forms of these pollutants is stored in the downstream riverbed sediments, and can be remobilized during high flow conditions. The study highlights the importance of coupled monitoring schemes on intermittent rivers.

We report a prediction for the delay measured in an optical tunneling experiment using Hong-Ou-Mandel (HOM) interference, taking into account the Goos-Hänchen shift generalized to frustrated total internal reflection situations. We precisely state assumptions under which the tunneling delay measured by an HOM interferometer can be calculated. We show that, under these assumptions, the measured delay is the group delay, and that it is apparently 'superluminal' for sufficiently thick air gaps. We also show how an HOM signal with multiple minima can be obtained, and that the shape of such a signal is not appreciably affected by the presence of the optical tunneling zone, thus ruling out the explanation of the anomalously short tunneling delays in terms of a reshaping of the wavepacket as it goes through the tunneling zone. Finally, we compare the predicted tunneling delay to a relevant classical delay and conclude that our predictions involve no non-causal effect. PMID:18825239

The New Absolute Parameters of OU Gem - The Star of BY Dra Type  

NASA Astrophysics Data System (ADS)

The spectra of OU Gem were obtained with the fiber-fed echelle spectrograph SOPHIE at the 1.93-m telescope of the Observatoire de Haute- Provence (France). The temperatures of components of the system were defined and are equal to 5013 ± 15 K and 4486±50 K for primary (A) and secondary (B) components, accordingly. The rotation velocity of components are measured: for primary component it is equal to 5.1±1 km/s and 6.2 ± km/s for the secondary one. The definition of radial velocities of components by LSD profile method and redetermination of spectral orbital elements were carried out. New absolute parameters of components were obtained too.

Cloning of bacterial genes specifying degradation of 4-chlorobiphenyl from Pseudomonas putida OU83.  

PubMed Central

Genes capable of 4-chlorobiphenyl (4-CBP) degradation were cloned from 4-CBP-degrading Pseudomonas putida OU83 by using a genomic library which was constructed in the broad-host-range cosmid vector pCP13. P. putida AC812 containing chimeric cosmid-expressing enzymes involved in the 4-CBP degradation pathway were identified by detecting 3-phenylcatechol dioxygenase activity (3-PDA). Chimeric cosmid clones pOH83, pOH84, pOH85, pOH87, and pOH88 positive for 3-PDA grew in synthetic basal medium containing 4-CBP (5 mM) as a carbon source. Restriction digestion analysis of recombinant cosmids showed DNA inserts ranging from 6 to 30 kilobase pairs. Southern hybridization data revealed that the cloned DNA inserts originated from strain OU83. Gas chromatography-mass spectrometry analysis of the metabolites of P. putida AC812(pOH88) incubated with 4-CBP and 4'-chloro-3-phenylcatechol showed the formation of 4-chlorobenzoic acid and benzoic acid. These results demonstrate that the cloned DNA fragments contain genes encoding for chlorobiphenyl dioxygenase (cbpA), dihydrodiol dehydrogenase (cbpB), 4'-chloro-3-phenylcatechol dioxygenase (cbpC), a meta-cleavage compound (a chloro derivative of 2-hydroxy-6-oxo-6-phenylhexa-2,4-dienoate) hydrolase (cbpD), and a new dechlorinating activity (dcpE). The location of the cbpC gene specifying 3-PDA was determined by subcloning an EcoRI DNA fragment (9.8 kilobase pairs) of pOH88 in plasmid vector pUC19. The cloned gene encoding 3-PDA was expressed in Escherichia coli HB101 and had substrate specificity only for 3-phenylcatechol and 4'-chloro-3-phenylcatechol. Images

Le syndrome du canal d'Alcock ou n?vralgie pudendale : un diagnostic ? ne pas m?conna?tre  

PubMed Central

Résumé Le syndrome du canal d’Alcock – ou névralgie pudendale – est lié à la compression chronique du nerf pudendal dans la fossette ischiorectale ou au niveau du ligament sacroépineux. Le diagnostic du syndrome d’Alcock est surtout clinique. Les examens complémentaires sont dominés par les explorations électrophysiologiques et le test de bloc anesthésique. Le diagnostic repose sur des critères bien précis, soit les critères de Nantes. La prise en charge doit être globale, comprenant un traitement médicamenteux, des infiltrations, des techniques de neuromodulation, et dans les cas graves ou résistants, un traitement chirurgical qui consiste à libérer le nerf pudendal. Les névralgies pudendales peuvent être rencontrées après traitement d’une incontinence urinaire d’effort par bande-lettes sous-urétrales (TVT). Ce syndrome motive des consultations en urologie, car la douleur intéresse le territoire du périnée et des organes génitaux. Des signes urinaires peuvent aussi accompagner cette douleur. Il est donc judicieux de connaître cette pathologie.

Progress in the thermodynamic modelling of the O-U binary system  

NASA Astrophysics Data System (ADS)

The fuel of civil nuclear plants, UO 2, melts at 3120 K. During an hypothetical severe accident, urania, submitted to high temperatures and various oxygen potentials, presents a wide non-stoichiometry range: the melting temperature of UO 2± x, related to oxygen potential, decreases in all cases. In this scenario, urania could react with other materials, firstly zircaloy, and the melting temperature of (U, Zr)O 2± x still decreases. That is why the critical assessment of the O-U binary system including the non-stoichiometry range of urania, is a major step to a correct thermodynamic modelling of multicomponent systems for nuclear safety. The very numerous experimental information has been compiled and analysed. The associate model was used for the liquid phase, and a sublattice model for UO 2± x; U 4O 9- y, U 3O 8 and UO 3 were treated as stoichiometric. Phase diagram and thermodynamic properties have been calculated from the optimised Gibbs energy parameters. The calculated consistency with the experimental ones is quite satisfactory.

Observation of Quantum Interference in the Plasmonic Hong-Ou-Mandel Effect  

NASA Astrophysics Data System (ADS)

Surface plasmon polaritons (SPPs) are electromagnetic excitations coupled to electron-charge density waves at metal-dielectric interfaces. They have recently been found to enable a range of nanophotonic devices for controlling systems at the quantum level, including single-photon sources, transistors, and ultracompact quantum circuitry. An important quantum feature of SPPs yet to be fully explored is their bosonic nature. In this work, we report direct evidence of the bosonic nature of SPPs in a scattering-based beam splitter. A parametric down-conversion source is used to produce two indistinguishable photons, each of which is converted into a SPP on a metal-stripe waveguide and then made to interact through a semitransparent Bragg mirror. In this plasmonic analog of the Hong-Ou-Mandel experiment, we measure a coincidence dip with a visibility of 72%, a key signature that SPPs are bosons and that quantum interference is clearly involved. Our work opens up possibilities for the study of fundamental quantum effects in plasmonic systems and their related applications.

Comparative analysis of the genomes of Rachiplusia ou and Autographa californica multiple nucleopolyhedroviruses.  


The Rachiplusia ou multiple nucleopolyhedrovirus (RoMNPV) is a variant of Autographa californica MNPV (AcMNPV) but is significantly more virulent against several major agricultural pests. The genome sequence of the R1 strain of RoMNPV was determined and compared to that of AcMNPV strain C6. The RoMNPV genome is approximately 131.5 kbp with a G+C content of 39.1 %. The homologous repeat regions (hrs) described for AcMNPV-C6 are present in RoMNPV-R1 but the hrs of RoMNPV have fewer palindromic repeats. The RoMNPV-R1 nucleotide sequence is almost completely collinear with the sequence of AcMNPV-C6 and contains homologues of 150 of the 155 ORFs described for AcMNPV-C6. Deletions, insertions and substitutions have resulted in the loss of homologues for AcMNPV ORFs ac2 (bro), ac3 (ctl), ac97, ac121 and ac140 from the RoMNPV genome. The average amino acid sequence identity between RoMNPV and AcMNPV ORFs is 96.1 % and there are differences in promoter motif composition for 23 of these ORFs. Maximum-likelihood analysis of selection pressures on AcMNPV and RoMNPV ORFs indicate that ORFs ro18/ac20-ac21 (arif-1) and ro135/ac143 (odv-e18) have undergone positive selection. PMID:12810877

Dephasing in single-electron generation due to environmental noise probed by Hong-Ou-Mandel interferometry  

NASA Astrophysics Data System (ADS)

We consider the effect of dephasing on a quantum dot which injects single electrons on a chiral edge channel of the quantum Hall effect. Dephasing is described by the coupling of the dot to a bosonic bath which represents the electromagnetic environment. Using the input-output formalism of quantum optics, we derive the density matrix of the edge degrees of freedom. Results are illustrated by computing the zero frequency current-current correlations when two such single-electron emitters achieve a collision at the location of a quantum point contact, in the same spirit as the Hong-Ou-Mandel experiment of quantum optics. Such correlations are directly linked to the quantum mechanical purity. We show that, as observed in a recent experiment, the effect of dephasing leads to a lifting of the Hong-Ou-Mandel dip when the time delay between the two electron wave packets is zero. Generalizations to time filtered wave packets as well as to asymmetric, detuned injection between opposite edges are obtained.

Catabolism of L-phenylalanine and L-tyrosine by Rhodobacter sphaeroides OU5 occurs through 3,4-dihydroxyphenylalanine.  


Rhodobacter sphaeroides OU5 utilized l-phenylalanine as sole source of nitrogen for growth. The metabolites of l-phenylalanine catabolism, i.e. 4-hydroxy phenylalanine (l-tyrosine), 3,4-dihydroxyphenylalanine (DOPA), 3,4-dihydroxyphenyl-pyruvic acid (DOPP), 3,4-dihydroxyphenyllactic acid (DOPLA), 3,4-dihydroxyphenyl-acetic acid (DOPAc) and 3,4-dihydroxybenzoic acid (PC), were identified using liquid chromatography-mass spectroscopy (LC-MS). With 2-oxoglutarate as an amino acceptor, DOPA aminotransferase activity was observed with cell-free extracts and the product DOPP was confirmed through mass analysis. Reductive deamination of DOPA also occurred in the absence of 2-oxoglutarate, whose products were 3,4-dihydroxyphenylpropionic acid (DPPA) and ammonia. The enzyme DOPA-reductive deaminase (DOPARDA) was purified to its homogeneity and characterized. DOPARDA has an obligate requirement for NADH and is functional at low concentrations of the substrate (<150 microM). The molecular mass of the purified enzyme was approximately 274kD and the enzyme could be a heterotetramer of 110, 82, 43 and 39kD subunits as determined by SDS-PAGE. PMID:17616348

The planetary nebula IPHASXJ211420.0+434136 (Ou5): insights into common-envelope dynamical and chemical evolution  

NASA Astrophysics Data System (ADS)

While analysing the images of the IPHAS (INT/WFC Photometric H? Survey of the northern Galactic plane) survey, we noticed that the central star of the candidate planetary nebula IPHASXJ211420.0+434136 (also named Ou5) was clearly variable. This is generally considered as an indication of binarity. To confirm it, we performed a photometric monitoring of the central star, and obtained images and spectra of the nebula. The nebular spectrum confirms that IPHASXJ211420.0+434136 is a planetary nebula of moderately high excitation. It has a remarkable morphology with two nested pairs of bipolar lobes and other unusual features. The light curve of the central star reveals that it is an eclipsing binary system with an orbital period of 8.74 h. It also displays a strong irradiation effect with an amplitude of 1.5 mag. The presence of multiple bipolar outflows adds constraints to the formation of these nebulae, suggesting the occurrence of discrete ejection events during, or immediately before, the common-envelope phase. IPHASXJ211420.0+434136 also adds evidence to the hypothesis that a significant fraction of planetary nebulae with close binary central stars have a peculiar nebular chemistry and a relatively low nebular mass. This may point to low-mass, low-metallicity progenitors, with additional effects related to the binary evolution. We also suggest that these objects may be relevant to understand the abundance discrepancy problem in planetary nebulae.

Geo-environmental risk in the upper valley of the Oued Sebou (Fès, Central Morocco): a preliminary approach  

NASA Astrophysics Data System (ADS)

In the framework of several projects sustained by the Regional Sardinian Government Laws no. 43 (28/09/1990) and no. 19 (11/04/1996), research groups of the University of Cagliari (Sardinia, Italy) and of the University Mohamed V-Agdal of Rabat (Morocco) have started a series of preliminary geo-environmental studies in the basin of the Oued Sebou. An area of almost 1000 square km around the famous city of Fès has been studied, using satellite images and two ground surveying campaigns. These surveys aim to define the geological and structural settings, the vegetation and land use, in order to define the landscape units and to select the areas of major hydrogeological and geo-environmental risk. The satellite data used are the LANDSAT TM5 images taken on the 9th of October 1997. These images have been analysed to obtain the different bases for further thematic mapping, resulting in the geo-environmental map of the area around Fès that constitutes an up-to-date representation of the geological and environmental state of the territory and a useful instrument for further risk assessment and urban and territorial planning.

L’asplénie, qu’elle soit fonctionnelle ou anatomique, s’associe à un accroissement du risque d’infection potentiellement fatale ou constituant un danger de septicémie postsplénectomie (SPS). En raison du risque accru de bactériémie par des bactéries encapsulées chez les enfants aspléniques, la vaccination visant à prévenir une infection au Streptococcus pneumoniae, à l’Haemophilus influenzae de type b (Hib) et au Neiserria meningitidis est recommandée. Malgré la prévalence croissante de S pneumoniae pénicillinorésistant, on recommande aussi l’usage de pénicilline prophylactique chez les enfants aspléniques de moins de cinq ans, et pendant au moins un an après une splénectomie. La poursuite de la prophylaxie antibiotique après cette période dépend de la situation clinique de chaque enfant et de la prévalence de S pneumoniae pénicillinorésistant au sein de la collectivité. Lorsque des enfants aspléniques font de la fièvre ou présentent des symptômes non spécifiques, ils devraient faire l’objet d’une évaluation immédiate. Si on présume la présence de septicémie bactérienne, il faut procéder à une analyse du sang et des autres liquides organiques pertinents et entreprendre sur-le-champ une antibiothérapie à large spectre par voie parentérale, laquelle doit agir également contre les souches de S pneumoniae présentes dans la collectivité. Chez les enfants aspléniques souffrant d’une septicémie foudroyante à S pneumoniae, le taux de mortalité est élevé, malgré l’utilisation rapide d’une antibiothérapie convenable, d’où l’importance des mesures préventives.



Substitution for petroleum products in Brasil: Urgent issues  

SciTech Connect

Brazililan energy policy during the last decade has focused on the replacement of imported petroleum with domestic energy sources, combined with efforts at conservation. The substitution results, however, have been more spectacular by far. The strategy of replacement is based on two elements. first, to increase domestic petroleum exploration and production. Second, to promote non-petroleum fuels as alternatives to the industrial and transportation sectors, for the substitution of fuel oil and gasoline, respectively. A combination of the substitution strategy, the country's petroleum refining structure, and the composition of the substitution strategy, the country's petroleum refining structure, and the composition of demand, has resulted in large surpluses of both gasoline and fuel oil, while diesel has become the most used among petroleum products. The surpluses are not easily exportable because there is ample availability of fuel oil in the world market, and because the low octane number of the gasoline produced in Brasil is not compatible with the engines of cars elsewhere in the region and in the world. Furthermore, although gasoline might be upgraded, the question remains that prospects for the world market are not encouraging, and an export-based strategy does not seem justified in view of the growing surpluses. The objective of this analysis is to review the mechanisms of themajor petroleum-substitution programs currently in existence, identifying their past impact on the energy market and the possible consequences of changes in the goals and operating conditions of these programs, in the light of the new prospects for increased domestic oil production and self-sufficiency. 23 refs., 2 figs., 1 tab.

Resultados do desenvolvimento de um propulsor à plasma no Brasil  

NASA Astrophysics Data System (ADS)

Uma das partes mais importantes de um satélite é o controle de atitude do mesmo. E se tratando de um satélite científico, a atenção para este sistema deve ser redobrada. Uma possibilidade atraente para executar esta tarefa é a propulsão elétrica. Aqui, mostraremos resultados obtidos pelo propulsor à plasma PHALL-01, desenvolvido na Universidade de Brasília entre 2000 e 2003. Este é derivado do propulsor russo SPT-100 (Stationary Plasma Thruster), mas com o emprego inovador de um arranjo de imãs permanentes como fonte do campo magnético, este último o agente da aceleração do plasma. Esta alteração foi motivada pelo objetivo de que o mesmo operasse com o mínimo de potência elétrica. A partir da formulação teórica do mecanismo de aceleração, tendo como base as equações da magnetohidrodinâmica, pode-se obter vínculos sob os quais o propulsor pudesse ser construído. O mais forte destes é o que dita a topologia do campo magnético. Sendo assim, foram realizadas simulações computacionais, que definiram a geometria do propulsor. Após construído, este foi diagnosticado usando-se sondas de Langmuir e analisadores de energia. Como resultados, obtivemos a distribuição espacial da temperatura, densidade e potencial do plasma, bem como a distribuição angular do feixe produzido pelo mesmo em vários regimes de operação. O espectro de energia do feixe de plasma também foi medido, indicando íons de até 560eV. Combinando estes resultados, calculou-se o empuxo do propulsor: 84mN; e o impulso específico: 1083s. Estes demonstram que o mesmo estará qualificado, num futuro próximo, para o emprego no controle de atitude de satélites científicos, ou até mesmo como parte do conjunto propulsor primário, responsáveis pela transferência de órbitas.

Although several total petroleum systems may exist within each of these basins, only three ?composite? total petroleum systems were identified. Each total petroleum system occurs in a separate basin, and each comprises a single assessment unit. The main source rocks are the Silurian Tanezzuft Formation (or lateral equivalents) and Middle to Upper Devonian mudstone. Maturation history and the major migration pathways from source to reservoir are unique to each basin. The total petroleum systems were named after the oldest major source rock and the basin in which it resides. The estimated means of the undiscovered conventional petroleum volumes in total petroleum systems of the Trias/Ghadames Province are as follows: [MMBO, million barrels of oil; BCFG, billion cubic feet of gas; MMBNGL, million barrels of natural gas liquids] Total Petroleum System MMBO BCFG MMBNGL Tanezzuft-Oued Mya 830 2,341 110 Tanezzuft-Melrhir 1,875 4,887 269 Tanezzuft-Ghadames 4,461 12,035 908

Heavy metals analysis of water, soils and sediments along the Oued Boufekrane river (central Morocco) using WD-XRF and ICP-AES  

NASA Astrophysics Data System (ADS)

Oued Boufekrane is a river that takes its source about thirty kilometers southern the city of Meknes central Morocco) The water of this river is used for the irrigation of agricultural soils and it also covers the needs of water for part of rural population. When passing through Meknes city, it is loaded by waste waters of urban and industrial origin and particularly from artisanal tanneries and potteries. The purpose of this study is to measure the heavy metal concentrations in soil, sediment and water samples along the Oued Boufekrane river by means of WD-XRF and ICP-AES. The heavy metals content measured revealed to be below the critical levels defined as risk levels except for Cu in water and sediment which content, in some sites, is close to these risk levels; forCr in sediments, which content increase from up- to downstream of Meknes city and for Pb in soils, which concentrations revealed to be high in the vicinity of road axes.

D?tention provisoire des jeunes femmes accus?es d'avortement clandestin ou d'infanticide au S?n?gal  

PubMed Central

Introduction L'activité sexuelle chez les jeunes les expose à un accroissement du risque de contracter des grossesses non désirées. Le recours à l'avortement clandestin avec son corollaire de complications peut entrainer le décès de la jeune femme. Avortement et infanticide sont interdits et sanctionnés par la loi sénégalaise. Comment ces jeunes femmes vivent-elles leur détention? Existe-il des alternatives à la détention pour éviter leur désocialisation? Méthodes Cette étude rétrospective portait sur la maison d'arrêt des femmes de Dakar située à Liberté 6, un quartier de Dakar. Nous avons procédé à des entretiens avec des femmes détenues à la maison d'arrêt des femmes de Dakar et suspectées d'infanticide ou d'avortement clandestin. Résultats Les femmes de notre échantillon ont une moyenne d’âge inférieure à 25 ans avec parmi elles une fille mineure de 16 ans. Nous avons trouvé 18,51% de femmes suspectées d'infanticide ou d'avortement. Dans notre étude 50% des femmes sont originaires de la périphérie et de la banlieue de Dakar et presque 44% proviennent des autres régions du pays. La durée moyenne de détention provisoire est de neuf mois. Conclusion Malgré leur qualification distincte dans le code pénal: l'infanticide est un crime et l'avortement un délit, les femmes suspectées d'avoir commis ces actes sont soumises à de longues détentions préventives.

Calcification and silicification: fossilization potential of cyanobacteria from stromatolites of Niuafo'ou's Caldera Lakes (Tonga) and implications for the early fossil record.  


Calcification and silicification processes of cyanobacterial mats that form stromatolites in two caldera lakes of Niuafo'ou Island (Vai Lahi and Vai Si'i) were evaluated, and their importance as analogues for interpreting the early fossil record are discussed. It has been shown that the potential for morphological preservation of Niuafo'ou cyanobacteria is highly dependent on the timing and type of mineral phase involved in the fossilization process. Four main modes of mineralization of cyanobacteria organic parts have been recognized: (i) primary early postmortem calcification by aragonite nanograins that transform quickly into larger needle-like crystals and almost totally destroy the cellular structures, (ii) primary early postmortem silicification of almost intact cyanobacterial cells that leave a record of spectacularly well-preserved cellular structures, (iii) replacement by silica of primary aragonite that has already recrystallized and obliterated the cellular structures, (iv) occasional replacement of primary aragonite precipitated in the mucopolysaccharide sheaths and extracellular polymeric substances by Al-Mg-Fe silicates. These observations suggest that the extremely scarce earliest fossil record may, in part, be the result of (a) secondary replacement by silica of primary carbonate minerals (aragonite, calcite, siderite), which, due to recrystallization, had already annihilated the cellular morphology of the mineralized microbiota or (b) relatively late primary silicification of already highly degraded and no longer morphologically identifiable microbial remains.

Impact of climate change on sediment yield in the Mekong River Basin: a case study of the Nam Ou Basin, Lao PDR  

NASA Astrophysics Data System (ADS)

This paper evaluates the impact of climate change on sediment yield in the Nam Ou Basin located in Northern Laos. The Soil and Water Assessment Tool (SWAT) is used to assess future changes in sediment flux attributable to climate change. Future precipitation and temperature series are constructed through a delta change approach. As per the results, in general, temperature as well as precipitation show increasing trends in both scenarios, A2 and B2. However, monthly precipitation shows both increasing and decreasing trends. The simulation results exhibit that the wet and dry seasonal and annual stream discharges are likely to increase (by up to 15, 17 and 14% under scenario A2; and 11, 5 and 10% under scenario B2 respectively) in the future, which will lead to increased wet and dry seasonal and annual sediment yields (by up to 39, 28 and 36% under scenario A2; and 23, 12 and 22% under scenario B2 respectively). A higher discharge and more sediment flux are expected during the wet seasons, although the changes, percentage-wise, are observed to be higher during the dry months. In conclusion, the sediment yield from the Nam Ou Basin is likely to increase with climate change, which strongly suggests the need for basin-wide sediment management strategies in order to reduce the negative impact of this change.

This article describes the development of the Brazilian Longitudinal Study for Adult Health (ELSA-Brasil) questionnaire. We first address the selection of topics whose contents have to cover the knowledge available on the complex causal network of outcomes and allow comparability with similar studies. Then we deal with the "translation and adaptation of measurement instruments" including neighborhood environment rating scales, depression and anxiety disorder rating scale and a food frequency questionnaire and discuss criteria that guided "theme block sequencing". And finally we focus on the practical importance of "pretesting and pilot studies". The ELSA may provide an original contribution regarding factors that cause or aggravate the outcomes of interest in the Brazilian population, as well as protective factors. PMID:24346718

Reproductive biology of the characid dourado Salminus franciscanus from the São Francisco River, Brasil.  


The neotropical characid Salminus franciscanus is an economically valuable migratory fish whose populations have been drastically reduced in recent decades due to industrial and economic development in Brasil. To study its reproduction, a total of 283 adult specimens were captured in the Upper São Francisco River, downstream from the Três Marias dam, Minas Gerais, south-eastern Brasil, from August 2009 to July 2010. The gonadal maturity stages were determined from histological features of the gonads and gonadosomatic index (GSI). Gametogenesis was assessed by light and electron microscopy. For analysis of the oocyte's surface and fecundity, mature females were subjected to hormonal induction and oocyte stripping. Fish in resting (Stage 1) were common in all samplings, ripening/ripe and spawning (Stages 2 and 3) were predominant in October-November and December-January and post-spawning (Stage 4) occurred from December-January extending until April-May. The GSI followed the morphological changes of gonadal maturation, with a peak in October-November, when maximum GSI (7.08 in females and 3.46 in males) was achieved. From scanning electron microscopy, stripped oocytes showed a funnel-shaped micropyle and a simple oocyte surface arrangement, which is typical for non-adhesive eggs. Fecundity ranged from 160 to 440×10(3) oocytes per female and 129 to 175×10(3)oocytes/kg. The results of this study indicate that S. franciscanus reproduces in the Upper São Francisco River from October to January, exhibiting a total spawning pattern, non-adhesive eggs and high fecundity, providing support for aquaculture and conservation biology of this important neotropical characid fish.

[The "Farmácia Popular do Brasil" Program and aspects of public provision of medicines in Brazil].  


In 2004, the Federal Government introduced the "Farmácia Popular do Brasil" Program, which was an example of policy innovation, establishing a co-payment scheme as a strategy for access to medication. The study analyzed the original model of the Program. Data were obtained from interviews with key stakeholders, program documents and user prescriptions and registers. The results showed widespread expansion of the PFPB network and in the number of people attended. Despite the ever-increasing number of people attended with prescriptions from the private sector, a large demand from public sector users, namely the original focus of the program, was observed. From the standpoint of the federative pact, the program reinstates the centralized model of essential medication distribution which, in the decentralized public system is under state and municipal responsibility. The results point to the difficulty in compliance by states and municipalities with medication distribution responsibilities, mainly in the North and Northeast regions of Brazil. The study concludes that the population has been consistently turning to the PFPB for essential medication it has not been able to access in the public sector. PMID:21709993

Maternal education, anthropometric markers of malnutrition and cognitive function (ELSA-Brasil)  

PubMed Central

Background The early exposure to poor social and nutritional conditions may influence cognitive function during adult age. However, the relative impact of these factors has not yet been established and they can vary during the course of life. Methods Analysis of data from 12,997 participants (35-64 years) of the baseline exams (2008-2010) of the Longitudinal Study of Adult Health (ELSA-Brasil), a cohort of Brazilian civil servants. Four cognitive tests were applied: learning, recall and word recognition; semantic and phonemic verbal fluency; trail-making test version B. The markers of early nutritional and social conditions were maternal educational level, birth weight, and length of trunk and leg. The presence of independent association between every early marker and the poor performance in each cognitive test was investigated by multiple logistic regression, after mutual adjustment and considering the effects of gender, age and participant’s schooling level. The cut off for poor performance was the worst age-specific percentile of the final score distribution for each test. Results After full adjustments, lower maternal education increased the chances of poor performance in all cognitive tests, with a dose-response gradient; low birth-weight was related to poor performance in the trail-making test B (OR?=?1.63, 95% IC?=?1.29-2.06); and greater trunk length decreased the chances of poor performance in the semantic and phonemic verbal fluency (OR?=?0.96, 95% IC?=?0.94-0.97) and in the trail-making test B (OR?=?0.94, 95% IC?=?0.92-0.95). Leg length was not associated with any of the tests examined. The associations found were not modified by the educational attainment of the participants. Conclusions Early exposure to adverse social and nutritional conditions appear detrimental to semantic memory, learning, concentration, executive control and language among adults, independent of adulthood educational achievement.

Low velocity zone beneath the central Ou Backbone Range of Tohoku, northeast Japan, bounded by active reverse faults, derived from dense seismic array and a tomographic method with spatial correlation of velocities  

NASA Astrophysics Data System (ADS)

The Tohoku arc is located in the northeastern Honshu, Japan. The Ou Backbone Range runs through the Tohoku arc in the N-S direction and is bounded by active reverse faults in the middle part of the arc. There were several large in-land earthquakes associated with the active faults. The purpose of the present study is to understand the relation between deep structure of active faults and 3-D velocity structures. From 1997 to 1999, the Japanese university group carried out an intensive seismic observation campaign in the central part of the Tohoku arc. We also conducted a dense seismic array observation (DSO) of microearthquakes using off-line seismic stations in the area bounded by the active faults. We obtained 33,993 P- and 18,483 S-wave arrivals from 706 natural sources and 40 quarry blasts for traveltime inversion analysis. We also used 2,803 P-wave traveltime data from 10 explosives in 1997 obtained by the RGES for our study. We used a traveltime inversion method with spatial correlation of velocities (Matsubara et al., 2001). We divide the medium into four layers by three seismic velocity discontinuities. We assume a three dimensional (3-D) grid net individually for each layer to express the 3-D velocity structure. We located grid nodes in the horizontal direction at 2.5-km spacing in the upper crust, at 10-km spacing in the lower crust, and at 30-km spacing in the mantle wedge in the Pacific Plate. We relocated hypocenters and origin time of 706 earthquakes and horizontal location and origin time of 27 quarry blasts. We solved 706 x 4 + 27 x 3 hypocentral parameters and 18,539 slowness unknowns of VP and 17,916 of VS. We used a modified two-dimensional (2-D) velocity model derived by a refraction study (Iwasaki et al., 2001) as an initial velocity structure. Each layer has a one-dimensional velocity distribution, which is model by averaging Iwasaki_fs 2-D model. The RMS of P-wave travel time residuals is 0.343 s before the inversion and is reduced to 0.186 s after 19 iterations. That of S-wave is 0.441 s before the inversion and is reduced to 0.280 s. Beneath the area of DSO, the inversion gives 5-10 % low VP and VS beneath the Kitakami Low Land at the surface. We also observe a 6-8 % lower VP zone and 2-6 % lower VS zone than the average velocity beneath the Ou Backbone Range. This zone is located at depths of 5-15 km and elongated about 18 km from north to south with a about 10-km width in E-W direction. The low velocity zone coincides with the electrically conductive zone derived from a magnetotelluric study (Ogawa et al. 2001). Array seismic observations over the eastern half of the Backbone Range mapped seismic scatterers using natural and artificial seismic sources (Asano et al., 1999). These correlations suggest that an element of mid-crustal low velocity zone will be interpreted as fluids. In spite of low velocity, the values of VP/V_S ratio are 1.65-1.70. These values are smaller than that of solid granite, 1.70. We can interpret that the fluid is aqueous not molten rock (Mavko, 1980; Takei, 2002; Watanabe, 1994). We can estimate liquid fraction with application of the values of 6.27 km/s VP, which is 8.3 % lower than that in solid granite, 3.68 km/s VS, which is 5.16 % lower, and 1.65-1.70 VP/V_S into Takei_fs theory (Takei, 2002). The liquid volume fraction is a range of 0.3-5 %.

Autographa californica multiple nucleopolyhedrovirus ODV-E56 envelope protein is required for oral infectivity and can be substituted functionally by Rachiplusia ou multiple nucleopolyhedrovirus ODV-E56.  


The Autographa californica multiple nucleopolyhedrovirus (AcMNPV) odv-e56 gene encodes an occlusion-derived virus (ODV)-specific envelope protein, ODV-E56. In a previous analysis, the odv-e56 gene was found to be under positive selection pressure, suggesting that it may be a determinant of virus host range. To assess the role of ODV-E56 in oral infectivity and host range, we constructed recombinant AcMNPV clones (Ac69GFP-e56lacZ and AcIEGFP-e56lacZ) in which ODV-E56 protein synthesis was eliminated by inserting a beta-galactosidase (lacZ) expression cassette into the odv-e56 open reading frame. We also constructed a recombinant virus, Ac69GFP-Roe56, in which the native AcMNPV odv-e56 coding sequence was replaced with that of Rachiplusia ou multiple nucleopolyhedrovirus (RoMNPV), a closely related virus that is significantly more virulent towards some host species than AcMNPV. The odv-e56 recombinant viruses exhibited no alterations in polyhedron production and morphogenesis or in the production of infectious budded virus in cell culture. In bioassays using three lepidopteran host species, the oral infectivities of the odv-e56 mutant viruses Ac69GFP-e56lacZ and AcIEGFP-e56lacZ were profoundly impaired compared with those of wild-type and control recombinant viruses. Oral infectivity was restored fully by marker rescue of the odv-e56 mutant viruses with either the AcMNPV or the RoMNPV odv-e56 gene. In bioassays using two host species that are more susceptible to RoMNPV than to AcMNPV, Ac69GFP-Roe56 killed larvae with LC50 values similar to those of recombinant viruses expressing AcMNPV ODV-E56. This result indicated that replacement of the AcMNPV odv-e56 gene with the RoMNPV orthologue did not increase virulence against these two species. PMID:20032203

Reliability of the MacArthur scale of subjective social status - Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)  

PubMed Central

Background The MacArthur Scale of Subjective Social Status intend to measure the subjective social status using a numbered stepladder image. This study investigated the reliability of the MacArthur scale in a subsample of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Method Three scales were employed using different references: 1) the overall socioeconomic position; 2) the socioeconomic situation of the participant’s closer community; 3) the workplace as a whole. A total of 245 of the ELSA participants from six states were involved. They were interviewed twice by the same person within an interval of seven to fourteen days. The reliability of the scale was assessed with weighted Kappa statistics and intraclass correlation coefficient (ICC), with their respective 95% confidence interval (CI). Results Kappa values were 0.62(0.58 to 0.64) for the society ladder; 0.58(0.56 to 0.61) for the community-related ladder; and 0.67(0.66 to 0.72) for the work-related ladder. The ICC ranged from 0.75 for the work ladder to 0.64 for the community ladder. These values differed slightly according to the participants’ age, sex and education category. Conclusion The three ladders showed good stability in the test-retest, except the community ladder that showed moderate stability. Because the social structure in Brazil is rapidly changing, future qualitative and longitudinal studies are needed to confirm and understand the construct underlying the MacArthur Scale in the country.

Negative life events and migraine: a cross-sectional analysis of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) baseline data  

PubMed Central

Background Stress is a typical migraine trigger. However, the impact of negative life events on migraine activity is poorly studied. The aim of this study is to investigate the association between negative life events and migraine using data from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) baseline assessment. Methods ELSA-Brasil is a multicenter cohort study conducted in six Brazilian cities. Baseline assessment included validated questionnaires for headache classification and the occurrence of five pre-specified negative life events (financial hardship, hospitalization other than for childbirth, death of a close relative, robbery and end of a love relationship), focusing on a 12-month period before evaluation. We built crude and adjusted logistic regression models to study the association between the occurrences of negative life events and migraine diagnosis and activity. Results We included 4,409 individuals with migraine and 4,457 participants without headache (reference). After adjustment for age, sex, race, income and educational level, we found that the occurrence of a negative life event (Odds ratio?=?1.31; 95% confidence interval?=?1.19 – 1.45) was associated with migraine. However, after stratifying with subgroup analyses, only financial hardship (Odds ratio?=?1.65; 95% confidence interval?=?1.47 – 1.87) and hospitalization (Odds ratio?=?1.47; 95% confidence interval?=?1.25 – 1.72) were independently associated with migraine. Further adjustment for a current major depression episode and report of religious activity did not significantly change the results. Considering migraine frequency as (a) less than once per month, (b) once per month to once per week, or (c) more than once per week, financial hardship and hospitalization remained significantly associated with migraine in all episode frequency strata, with higher odds ratios for higher frequencies in adjusted models. We also observed a significant association between the death of a close relative and the highest migraine frequency stratum (Odds ratio?=?1.38; 95% confidence interval?=?1.09 – 1.75) in full-adjusted model. Conclusions The occurrence of financial hardship and hospitalization had a direct and independent association with migraine diagnosis and frequency. The death of a close relative was also independently associated with the highest migraine frequency stratum.

Le pore nucléaire: machine biochimique ou démon de Maxwell?  

NASA Astrophysics Data System (ADS)

The nuclear pore complex sits as the gateway between the genomic, nuclear environment and the primarily enzymatic realm of the cytoplasm. Large channels traversing the two membranes of the nuclear envelope, the nuclear pores govern the passage of specific molecules between these two major compartments of the cell. Its ability to limit passage to specific molecules, and furthermore to pump them against a gradient in concentration, raises intriguing physical questions. This article reviews basic aspects of the structure and operation of this biochemical pump, whose thermodynamic cycle differs from that of conventional machines.

Earlier age at menarche is associated with higher diabetes risk and cardiometabolic disease risk factors in Brazilian adults: Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)  

PubMed Central

Objectives Early menarche has been linked to higher risk of type 2 diabetes in Western and Asian societies, yet whether age at menarche is associated with diabetes in Latin America, where puberty and diabetes may have different life courses, is unknown. We tested the hypothesis that earlier menarche is associated with higher diabetes risk in Brazilian adults. Methods We used data from 8,075 women aged 35-74 years in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) who had complete information on age at menarche, diabetes status, and covariates. Diabetes was defined based on self-reported physician diagnosis, medication use, and laboratory variables (fasting glucose, 2-hour glucose, and glycated hemoglobin). Poisson regression was used to generate risk ratios (RR) and 95% confidence intervals (CI). Results Menarche onset < 11 years [vs. 13-14 years (referent)] was associated with higher risk of diabetes (RR = 1.34; 95% CI: 1.14-1.57) after adjusting for sociodemographic factors, maternal education, maternal and paternal diabetes, and birth weight. This persisted after further control for BMI at age 20 years and relative leg length. Additionally, among those not taking diabetes medications, earlier menarche [<11 years vs. 13-14 years (referent)] was associated with higher % glycated hemoglobin (p < 0.001), alanine aminotransferase (p < 0.001), triglycerides (p < 0.001), C-reactive protein (p = 0.003), waist circumference (p < 0.001), and BMI measured at baseline exam (p < 0.001). Conclusion These findings support the hypothesis that earlier menarche is associated with greater risk for adult diabetes and cardiometabolic disease in the Brazilian context.

The main objective is value the geological heritage of the Ilha do Fogo (Cabo Verde), Seridó in State of Rio Grande do Norte (Brasil) , Sabugal in Beira Alta province (Portugal) and Arquipélago dos Açores (Portuguese autonomous region). These regions have a great geological heritage like volcanology, plutonic rocks, sedimentar formations, metamorphic, paleontologic, mineralogic, geomorphologic, hydric and mining resources. Such heritage is being used in the different regions has base of studies to senior scientists and were used to great scientific researches. The diversified and distinguished cultural heritage of these four regions is referenced and it's a value to the union of the students from these three continents, with the Portuguese language as communication tool. The variety of the geological wealth and cultural of these regions, results in the common objective of their valuing like Geoparks. His creation on these three regions is a strategy with a great relevance to the socio-economic development. With the creation of this game, we promote the union of these 3 countries from these three continents, the universal values of the heritage richness that are offered by our planet.

Performances comparées des machines à aimants et à réluctance variable. Maximisation du couple massique ou volumique  

NASA Astrophysics Data System (ADS)

The subject of this article is to compare the performances of electrical machines using three different principles of functioning which are recently exploited. We consider possibilities to realise actuators with high torque and power per unit of mass for direct drive applications. The three different machines involved in the comparison are: (i) the classical synchronous structure with permanent magnets in the inductor, (ii) the vernier reluctance structure, (iii) the vernier reluctance structure with permanent magnets. To allow a good comparison, the architecture of those three motors has to be identical, particularly the shape of the main elements. L'objet de cet article est de comparer directement, pour la première fois à notre connaissance, les performances de machines électriques mettant en oeuvre trois principes de fonctionnement différents, très récemment exploités. Nous examinons les possibilités de réalisation d'actionneurs à fort couple et puissance massique élevée, pour des applications d'entraînement direct, conçus à partir soit d'une structure synchrone classique utilisant des aimants pour l'inducteur, soit d'une structure à réluctance variable vernier soit, enfin, d'un dispositif combinant l'effet de réluctance variable à l'utilisation d'aimants. Pour permettre une comparaison réellement directe, l'architecture des trois moteurs exploitant les concepts évoqués, ainsi que la forme de leurs principales pièces, seront pratiquement identiques.

Using statistics to determine data adequacy for environmental policy decisions (shootout at the OU-3 corral)  

SciTech Connect

The discipline of statistics often plays an important role in environmental policy decision-making, when decisions are, if not completely based on, at least informed by environmental data. Statistics provides guidance for the type, quantity, and quality of data required to support the policy decisions, as well as the techniques for assessing the data once it is collected. Environmental policy decisions occur at many levels, national, regional, state, and local. This paper describes the use of statistics to support policy decisions at the local level. Even at the local level, decisions can involve millions and, in some cases, billions of dollars. Additionally, local policy decisions can have ramifications for policy decisions at the state, regional and national levels. The two major regulations that drive environmental restoration are the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) (also known as Superfund), and the Resource Conservation and Recovery Act (RCRA). In many areas state water quality standards and other requirements are also important drivers. The United States Environmental Protection Agency (USEPA) has placed the statistician right in the center of the environmental restoration work. It has done this by issuing guidance that recommends that planning for environmental data collection follows the Data Quality Objectives (DQO) Process (USEPA 1994), and evaluation of the data follows the Data Quality Assessment (DQA) Process (USEPA 1996). These processes are based on formal statistical techniques such as hypothesis testing and estimation, and explicitly link data collection to risk management decisions through specification of acceptable levels for statistical decision errors.

L’insensibilité congénitale à la douleur est une affection rare qui peut être responsable de l’apparition accidentelle de lésions externes et internes chez l’enfant. Dans un contexte de présomptions de sévices à des enfants, le fait de connaître l’existence de cette affection peut compliquer l’interprétation médico-légale de nos constatations. Le diagnostic d’insensibilité congénitale à la douleur, dans la forme qui nous intéresse, nécessite plusieurs éléments : l’absence de sensibilité à la douleur depuis la naissance, l’atteinte de la totalité de la surface corporelle, l’intégrité des réflexes ostéo-tendineux et des autres modes de sensibilité, la négativité des examens paracliniques, y compris histologiques. Nous présentons un cas de deux enfants de la même fratrie, examinés dans le cadre d’une procédure judiciaire d’urgence au sein de l’unité de médecine légale du Centre hospitalo-universitaire de Grenoble, en France. L’interprétation médicolégale des faits et de l’examen doit être prudente en cas de complications judiciaires et faire suite à une analyse des problèmes médico-sociaux de l’enfant depuis sa naissance et de ceux de sa famille. Le soutien socio-éducatif de ces familles et la transmission d’information sur cette maladie doivent être une priorité afin d’éviter tout dépassement dans la prise en charge et la surveillance de l’enfant et tout quiproquo face aux autres.

Imagerie par contraste en reflexion ou transmission lors d'une procedure par laser au dioxyde de carbone  

NASA Astrophysics Data System (ADS)

The use of laser micromachining is now reaching maturity. Laser micromachining is now competing with traditional methods in procedures such as welding, cutting or melting. This thesis will focus on various aspects of the uses of laser in the industry. In each aspect we are drawing our attention on the method to image a given procedure in real-time. In this manuscript we are applying Maxwell's equations to describe the propagation of an electromagnetic wave across various interfaces between media. The approach is tantamount to using Fresnel equation by taking into account the thickness between two successive interfaces bounding a given medium. This theory becomes useful when investigating the evaporation of matter, welding of two dissimilar materials and etching at the surface of a substrate. The progression of welding and etching will be imaged in real-time using an effect of contrast. Various planes of observation that are available in our set-up will allow us to draw firm conclusions in real-time as the procedure develops. Using the principle of contrasting regions it was found that the progression of a laser procedure can be imaged and give interesting details as it evolves in time. It will be also possible to determine when it is time to stop the operation during a laser procedure when a substance evaporates on a substrate. In the case of a laser welding procedure, it will be shown that the imaging method can give some information about the quality of a weld between two different materials. Lastly, it will also be shown that we can image a laser etching procedure by using the contrast of reflectance in neighbouring regions.

Modalités de prise de décision chez les filles et les garçons en la présence ou en l'absence de l'enseignant  

NASA Astrophysics Data System (ADS)

How girls and boys take decisions in the presence and absence of a teacher - This work is part of an innovative approach to physical and sports education in Tunisia, and team sports in particular. It uses language studies carried out within the framework of this teaching both to generate a reflective attitude on the part of students, and to identify the effect of gender as a variable in the ways in which they make decisions. Discourse analysis highlights the importance of language output by girls and boys in football teaching when a teacher is present or absent. The teacher is an institutional authority who imposes specific uses of language, and when he/she is absent, emotional tensions predominate and may reflect the repression of ideas that occurs when the teacher is present. Although girls appear to take part in the discussion, their utterances are fewer in number, and their analytical statements less effective than those of boys. Girls never gain the upper hand over boys. The study also suggests a redefinition of social role divisions on the basis of gender - masculinity and femininity.

Magnetic Resonance Imaging versus Computed Tomography in Transient Ischemic Attack and Minor Stroke: The More ?ou See the More You Know  

PubMed Central

Background Magnetic resonance imaging (MRI) is proposed as the preferred imaging modality to investigate patients with transient ischemic attack (TIA). This is mainly based on a higher yield of small acute ischemic lesions; however, direct prospective comparisons are lacking. In this study, we aimed to directly compare the yield of acute ischemic lesions on MRI and computed tomography (CT) in the emergency diagnosis of suspected TIA or minor stroke. Methods Consecutive patients aged 18 years or older presenting with minor stroke (NIHSS <4) or high-risk TIA and who were examined by a stroke neurologist within 24 h of symptom onset were prospectively enrolled in the CATCH study. Patients who had undergone both a baseline CT and an MRI within 24 h of symptom onset were included in this substudy. Baseline MRI and CT were interpreted independently to identify an acute ischemic lesion. The rates of acute ischemic lesions on CT and MRI were compared, and the volume of acute ischemic lesions was measured on MRI. In addition, the volume of acute ischemic lesions on MRI was compared between patients who had evidence of acute ischemia on CT and in those who did not. Results A total of 347 patients were included, 168 with TIAs, 147 with minor strokes and 32 with a final diagnosis of a mimic. Acute ischemic lesions were detected in 39% of TIAs by using MRI versus 8% by using CT (p < 0.0001) and in 86% of minor strokes by using MRI versus 18% by using CT (p < 0.0001). Compared to MRI, CT had a sensitivity of 20% and a specificity of 98% in identifying an acute ischemic lesion. The infarct volume on diffusion-weighted MRI was larger in cases where the CT also showed an acute ischemic lesion (median 5.07 ml, IQR 10) as compared to lesions seen only on MRI (median 0.68 ml, IQR 1.31, p < 0.0001). Conclusion MRI is superior to CT in detecting the small ischemic lesions occurring after TIA and minor stroke. Since these lesions are clinically relevant, MRI should be the preferred imaging modality in this setting.

Effective remediation is dependent upon placing the oxidant in close contact with the contaminated aquifer. Therefore, monitoring tools that provide enhanced tracking capability of the injectate offer considerable benefit to guide subsequent ISCO injections. Time-series geophysical surveys were performed at a superfund site in New Hampshire, USA over a one-year period to identify temporal changes in the bulk electrical conductivity of a tetrachloroethylene (PCE; also called tetrachloroethene) contaminated, glacially deposited aquifer due to the injection of sodium permanganate. The ISCO treatment involved a series of pulse injections of sodium permanganate from multiple injection wells within a contained area of the aquifer. After the initial injection, the permanganate was allowed to disperse under ambient groundwater velocities. Time series geophysical surveys identified the downward sinking and pooling of the sodium permanganate atop of the underlying till or bedrock surface caused by density-driven flow, and the limited horizontal spread of the sodium permanganate in the shallow parts of the aquifer during this injection period. When coupled with conventional monitoring, the surveys allowed for an assessment of ISCO treatment effectiveness in targeting the PCE plume and helped target areas for subsequent treatment.

Rifting actif ou passif en Éthiopie ? éléments de réponse apportés par l'étude des xénolites péridotitiques de la région du lac Tana  

NASA Astrophysics Data System (ADS)

The comparative study of peridotitic xenoliths from Oligocene and Quaternary volcanic formations of north-western Ethiopia shows that the textural, mineralogical, thermal and geochemical characteristics of the lithospheric mantle of this region were acquired in Oligocene times. These data suggest that the impinging of the Afar plume beneath the Ethiopian lithosphere occurred prior to the traps emplacement and the Plio-Quaternary rifting. This favours a model of active rifting for the Afar triple junction.

Karyotype composition of some rodents and marsupials from Chapada Diamantina (Bahia, Brasil).  


The Chapada Diamantina (CD) is located in Bahia State, between 11-14 degrees S and 41-43 degrees W, being part of the Serra do Espinhaço. The occurrence of different habitats and transition areas permits an interesting mammal fauna composition, with species from different biomes living in sympatry. Species of Didelphimorphia and Rodentia are important members of mammal communities in almost all different habitats, and morphological and cytogenetic characters are important for a correct identification of most of these species. In this work 258 specimens of small mammals from the orders Didelphimorphia (six genera and six species) and Rodentia (two families, five Sigmodontinae tribes, nine genera and 11 species) were collected during the whole field work (44 nights with traps). Chromosome preparations were obtained from 145 specimens from the species: Marmosops incanus, Gracilinanus microtarsus, Monodelphis domestica, Akodon aff. cursor, Necromys lasiurus, Cerradomys sp., Oligoryzomys fornesi, O. nigripes, O. rupestris, Calomys expulsus, Rhipidomys macrurus, Wiedomys pyrrhorhinus and Thrichomys inermis. Didelphis albiventris, Micoureus demerarae, Thylamys karymii and Nectomys sp. were identified by morphological characters. Most analyzed specimens do not show karyotype variation. However, numerical chromosomic variation was found in two individuals of Akodon aff. cursor (2n = 15) and in one individual of Cerradomys sp. (2n = 51). Structural variation in karyotype was observed in seven individuals of Cerradomys sp., showing one additional pair of metacentric chromosomes. PMID:18094834

12 item allodynia symptom checklist/Brasil: cross-cultural adaptation, internal consistency and reproducibility.  


Since there was no Portuguese questionnaire to evaluate cutaneous allodynia, which has been pointed out as a risk factor of migraine, we aimed to perform the cross-cultural adaptation of the 12 item Allodynia Symptom Checklist for the Brazilian population and to test its measurement properties. It consisted in six stages: translation, synthesis, back translation, revision by a specialist committee, pretest and submission the documents to the committee. In the pretest stage, the questionnaire was applied to 30 migraineurs of both sexes, who had some difficulty in understanding it. Thus, a second version was applied to 30 additional subjects, with no difficulties being reported. The mean filling out time was 3'36", and the internal consistency was 0.76. To test reproducibility, 15 other subjects filled out the questionnaire at two different times, it was classified as moderate (weighted kappa=0.58). We made available to Brazilian population an easy, quick and reliable questionnaire. PMID:23175197

Background After hearing about the reproducible and excellent results of the Ponseti method for clubfoot treatment, a group of Brazilian orthopaedic surgeons organized and participated in a standardized national program to teach the Ponseti technique in 21 different cities across Brazil. Methods A total of 21 Ponseti symposiums were organized in a standard fashion from January, 2007 to December, 2008. They consisted of a two-day program with lectures, hands-on cast application, and discussion of local clinical cases presented by orthopaedic surgeons. Thirteen Brazilian orthopaedic surgeons, who had been trained by the University of Iowa or centers recognized by them, taught the method. Financial support for travel was provided by an English charity: La Vida (Vital Investment for Developing Aid in Latin America). The physicians who attended the symposiums answered questionnaires before and after the training. Results About 7% of the 8000 orthopaedic surgeons in Brazil (556 orthopaedic surgeons) were trained. These orthopaedic surgeons stated that they had treated about 4905 babies in the previous year via other methods, including extensive surgery. Seventeen percent of the surgeons did not know about the Ponseti technique at the start of the symposium. Eighty-eight percent reported they felt able to treat children with the Ponseti technique after the symposium. Ninety-four percent of respondents reported that the symposium changed their way of treating clubfoot Conclusions These Ponseti symposiums brought about an exchange of medical information and empowered the participants. This program is a good educational tool which can be used in eradicating neglected clubfoot in Brazil.

Rationale and design of the Patient Related OuTcomes with Endeavor versus Cypher stenting Trial (PROTECT): randomized controlled trial comparing the incidence of stent thrombosis and clinical events after sirolimus or zotarolimus drug-eluting stent implantation.  


Drug-eluting stents (DES) reduce restenosis rates compared to bare-metal stents. Most trials using DES enrolled selected patient and lesion subtypes, and primary endpoint focused on angiographic metrics or relatively short-term outcomes. When DES are used in broader types of lesions and patients, important differences may emerge in long-term outcomes between stent types, particularly the incidence of late stent thrombosis. PROTECT is a randomized, open-label trial comparing the long-term safety of the zotarolimus-eluting stent and the sirolimus-eluting stent. The trial has enrolled 8,800 patients representative of those seen in routine clinical practice, undergoing elective, unplanned, or emergency procedures in native coronary arteries in 196 centers in 36 countries. Indications for the procedure and selection of target vessel and lesion characteristics were at the operator's discretion. Procedures could be staged, but no more than 4 target lesions could be treated per patient. Duration of dual antiplatelet therapy was prespecified to achieve similar lengths of treatment in both study arms. The shortest predefined duration was 3 months, as per the manufacturer's instructions. The primary outcome measure is the composite rate of definite and probable stent thrombosis at 3 years, centrally adjudicated using Academic Research Consortium definitions. The main secondary end points are 3-year all-cause mortality, cardiac death, large nonfatal myocardial infarction, and all myocardial infarctions. This large, international, randomized, controlled trial will provide important information on comparative rates of stent thrombosis between 2 different DES systems and safety as assessed by patient-relevant long-term clinical outcomes.

Can a combined screening/treatment programme prevent premature failure of renal transplants due to chronic rejection in patients with HLA antibodies: study protocol for the multicentre randomised controlled OuTSMART trial  

PubMed Central

Background Renal transplantation is the best treatment for kidney failure, in terms of length and quality of life and cost-effectiveness. However, most transplants fail after 10 to 12 years, consigning patients back onto dialysis. Damage by the immune system accounts for approximately 50% of failing transplants and it is possible to identify patients at risk by screening for the presence of antibodies against human leukocyte antigens. However, it is not clear how best to treat patients with antibodies. This trial will test a combined screening and treatment protocol in renal transplant recipients. Methods/Design Recipients >1 year post-transplantation, aged 18 to 70 with an estimated glomerular filtration rate >30 mL/min will be randomly allocated to blinded or unblinded screening arms, before being screened for the presence of antibodies. In the unblinded arm, test results will be revealed. Those with antibodies will have biomarker-led care, consisting of a change in their anti-rejection drugs to prednisone, tacrolimus and mycophenolate mofetil. In the blinded arm, screening results will be double blinded and all recruits will remain on current therapy (standard care). In both arms, those without antibodies will be retested every 8 months for 3 years. The primary outcome is the 3-year kidney failure rate for the antibody-positive recruits, as measured by initiation of long-term dialysis or re-transplantation, predicted to be approximately 20% in the standard care group but <10% in biomarker-led care. The secondary outcomes include the rate of transplant dysfunction, incidence of infection, cancer and diabetes mellitus, an analysis of adherence with medication and a health economic analysis of the combined screening and treatment protocol. Blood samples will be collected and stored every 4 months and will form the basis of separately funded studies to identify new biomarkers associated with the outcomes. Discussion We have evidence that the biomarker-led care regime will be effective at preventing graft dysfunction and expect this to feed through to graft survival. This trial will confirm the benefit of routine screening and lead to a greater understanding of how to keep kidney transplants working longer.

Polycyclic aromatic hydrocarbons in sediments from Rodrigo de Freitas Lagoon in the urban area of Rio de Janeiro, Brasil.  


Regular (non-alkylated) polycyclic aromatic hydrocarbons (PAHs) and their alkylated homologues were determined in sediments from Rodrigo de Freitas Lagoon using gas chromatography with mass selective detector (GC-MSD). Concentrations varying from 405 to 11734 ng x g(-1) were found for total PAHs (regular and alkylated homologues). The study showed a pyrogenic and petrogenic contribution, probably due to the incomplete burning of fossil fuels as a result of the intense traffic of boats and motor vehicles added to the anthropogenic activity of several gas stations present in the region of Rodrigo de Freitas Lagoon. According to the National Oceanic and Atmospheric Administration (NOAA) Sediment Quality Guide, PAHs concentration should not exceed 4000 ng x g(-1) (Long et al., 1995) The obtained data present values above the NOAA limit for some sampling points indicating chronic contamination of those sites probably due to anthropogenic activities related to petroleum and its derivatives.

A high spatial resolution outdoor dose rate map of the Rio de Janeiro city, Brasil, risk assessment and urbanization effects.  


Geophysical surveys have been widely used for geological mapping, and with appropriate ground calibration the database can be converted to radiometric surveys. Herein we present a case study of a high resolution map of the City of Rio de Janeiro, Brazil, constructed by integrating aerial and in situ (ground) measurements. This allowed assessing the influence of urbanization observed between 1978 and 2009 on radiation external exposure. Radiometric, geological and demographics databases were integrated in a Geographic Information System (GIS) facility. The average absorbed dose rate recorded for the city was 96 ± 0.3 nGy h(-1) and ranged from 22 to 152 nGy h(-1) among districts. The corresponding annual effective dose was determined as 0.09 ± 0.01 mSv. The number of people at risk per year according to the estimated natural radiation levels was 17 ± 1.4, among the 28,000 new cases estimated by the INCA (Brazilian National Cancer Institute) within a population of approximately 6.3 million people.

Influence of structural, textural and superficial properties of solids.LE POINT SUR...CONCISE REVIEW PAPER  

NASA Astrophysics Data System (ADS)

A crucial step, leading to a proper understanding of adsorption mechanisms at the solid-aqueous solution interface, lies in the precise determination of the structural, textural and energetic properties of the solid phases under study. The various conventional techniques for characterizing the textural properties (specific surface area and porosity) are first reviewed. The use of a new adsorption volumetric technique in quasi-equilibrium conditions is then detailed. Using such a technique, the gas adsorption isotherm can be obtained precisely on the whole domain of monolayer filling. The DIS (Derivative Isotherm Summation) method applied to the experimental results then allows a study of the surface energetic heterogeneity, which was difficult to assess using conventional techniques. Two examples are then used to illustrate the potentialities of the technique. Through a judicious choice of the adsorbate, such analysis can be used to characterize the exchange properties of solids and to assign precisely the crystallographic origin of the Cationic Exchange Capacity (CEC) of kaolinite. It can also be utilized to understand the retention mechanisms of organic pollutants such as phenol on activated carbons.

The two metal centers of 1 share 4 unidentate bridging {mu}-ONc ligands and complete their octahedral geometry through the coordination of 4 monodentate terminal HONc ligands. The structure arrangement of the central core of 2a and b are identical, wherein 4 octahedral Sr atoms are arranged in a square geometry around a {mu}{sub 4}-O ligand. An additional 7-coordinated Sr atom sits directly atop the {mu}{sub 4}-O to form a square base pyramidal arrangement of the Sr atoms but the apical Sr-O distance is too long to be considered a bond. In solution, compound 1 is disrupted forming a monomer but 2a and b retain their structures.

A structural and palaeostress study of this platform near Quebec City allowed reconstructing its tectonic evolution since the Palaeozoic. The collapse of the Iapetus margin (NW-SE extension) has induced N040 normal faults. Appalachian compressions (WNW and north-south) have reactivated these border faults, and induced strike-slip faults trending N090 and N140. During the Mesozoic, NNE to NNW extensions have reactivated N090 and N040 faults. The following NE-SW compression has been active until today.

NASA Astrophysics Data System (ADS)

Very few data on Early Triassic marine ostracods are available. In most of cases, the data concern the upper part of the Early Triassic. The Çürük da? section, located in the Western Taurides (Turkey), well stratigraphically constrained by conodonts and foraminifera, has been re-sampled for ostracod study. A significant fauna has been discovered in the Late Permian and the levels of the Earliest Triassic ( Hindeodus parvus and Isarcicella isarcica staeschei zones). The ostracods of the basis of the Kokarkuyu Fm. are the oldest Triassic forms ever discovered. The occurrence of Palaeocopes in the earliest Triassic and similarity between the Permian and Induan assemblages suggest that the Lower Triassic Çürük da? ostracods represent a survival assemblage after the Permo-Triassic mass-extinction.

Landslide Susceptibility Analysis by the comparison and integration of Random Forest and Logistic Regression methods; application to the disaster of Nova Friburgo - Rio de Janeiro, Brasil (January 2011)  

NASA Astrophysics Data System (ADS)

The study of landslide susceptibility by multivariate statistical methods is based on finding a quantitative relationship between controlling factors and landslide occurrence. Such studies have become popular in the last few decades thanks to the development of geographic information systems (GIS) software and the related improved data management. In this work we applied a statistical approach to an area of high landslide susceptibility mainly due to its tropical climate and geological-geomorphological setting. The study area is located in the south-east region of Brazil that has frequently been affected by flood and landslide hazard, especially because of heavy rainfall events during the summer season. In this work we studied a disastrous event that occurred on January 11th and 12th of 2011, which involved Região Serrana (the mountainous region of Rio de Janeiro State) and caused more than 5000 landslides and at least 904 deaths. In order to produce susceptibility maps, we focused our attention on an area of 93,6 km2 that includes Nova Friburgo city. We utilized two different multivariate statistic methods: Logistic Regression (LR), already widely used in applied geosciences, and Random Forest (RF), which has only recently been applied to landslide susceptibility analysis. With reference to each mapping unit, the first method (LR) results in a probability of landslide occurrence, while the second one (RF) gives a prediction in terms of % of area susceptible to slope failure. With this aim in mind, a landslide inventory map (related to the studied event) has been drawn up through analyses of high-resolution GeoEye satellite images, in a GIS environment. Data layers of 11 causative factors have been created and processed in order to be used as continuous numerical or discrete categorical variables in statistical analysis. In particular, the logistic regression method has frequent difficulties in managing numerical continuous and discrete categorical variables together; therefore in our work we tried different methods to process categorical variables , until we obtained a statistically significant model. The outcomes of the two statistical methods (RF and LR) have been tested with a spatial validation and gave us two susceptibility maps. The significance of the models is quantified in terms of Area Under ROC Curve (AUC resulted in 0.81 for RF model and in 0.72 for LR model). In the first instance, a graphical comparison of the two methods shows a good correspondence between them. Further, we integrated results in a unique susceptibility map which maintains both information of probability of occurrence and % of area of landslide detachment, resulting from LR and RF respectively. In fact, in view of a landslide susceptibility classification of the study area, the former is less accurate but gives easily classifiable results, while the latter is more accurate but the results can be only subjectively classified. The obtained "integrated" susceptibility map preserves information about the probability that a given % of area could fail for each mapping unit.

Oxacilin-resistant Coagulase-negative staphylococci (CoNS) bacteremia in a general hospital at S?o Paulo city, Brasil  

PubMed Central

In the last decades, coagulase-negative staphylococci (CoNS), especially Staphylococcus epidermidis have become an important cause of bloodstream infections. In addition, rates of methicillin-resistance among CoNS have increased substantially, leading to the use of glicopeptides for therapy. The objective of this study was to evaluate eleven consecutives clinically relevant cases of oxacillin-resistant CoNS bacteremia in a general hospital localized in São Paulo city, Brazil. Five different species were identified by different phenotypic methods, including S. epidermidis (5), S. haemolyticus (3), S. hominis (1), S. warneri (1) and S. cohnii subsp urealyticus (1). A variety of Pulsed Field Gel Electrophoresis profiles was observed by macrorestriction DNA analysis in S. epidermidis isolates, but two of three S. haemolyticus isolates presented the same profile. These data indicated the heterogeneity of the CoNS isolates, suggesting that horizontal dissemination of these microorganisms in the investigated hospital was not frequent. One S. epidermidis and one S. haemolyticus isolates were resistant to teicoplanin and susceptible to vancomycin. The selective pressure due to the use of teicoplanin in this hospital is relevant.

Magnetic fabric and emplacement mechanisms in a co-mingled mafic and felsic magma chamber: the Espinharas granite (Borborema Province, NE Brasil)  

NASA Astrophysics Data System (ADS)

The Espinharas granite is a co-mingled mafic and felsic magmatic complex forming part of the widespread Brasiliano plutonism that affected the Borborema Province during the Neoproterozoic. Syenogranite is mixed and mingled with diorite generating a range of aluminous shoshonitic hybrid rocks containing mafic microgranular enclaves (MME) of various shapes and orientations. Geochemical modelling shows that the pluton originated by upper-mantle magma underplating and fault-assisted intrusion of diorite, which would supply heat for partial melting of the crust and formation of syenogranite. The Espinharas granite comprises syenogranites and diorites associated with quartz-monzonites, monzodiorites and syenites mainly deformed in the magmatic state. The pluton is emplaced within Paleoproterozoic augen gneisses from the basement and is bounded by high-temperature NE-trending mylonitic shear zones at its western and eastern borders. To the south, the pluton is in contact with the E-trending high-grade transpressional Patos shear zone. Magmatic foliations can be observed throughout the syenogranite and in the felsic rocks, being defined by a SPO of feldspars and quartz. However, they appear to be absent in the diorite. The microgranular enclaves display irregular contacts with the host syenogranite and may be often aligned in agreement with the magmatic foliation; they are also randomly dispersed and disrupted by monzo- to syenogranitic veins. The Anisotropy of Magnetic Susceptibility (AMS) technique was employed in order to investigate the mechanical relationships between mingled mafic and felsic magmas, as well as their emplacement mechanisms. Susceptibilities are usually high (k > 1.3 mSI), suggesting that Ti-magnetite is the main carrier of the magnetic signal. The magnetic lineation plunges shallowly to NE, parallel to the pluton main elongation axis. Zircons from diorite and syenogranite yield U-Pb (SHRIMP) ages of ~ 620 Ma, which are attributed to the crystallization of the granite and are younger than the main metamorphic event in the Seridó Belt (~ 575 Ma). These data suggest that the magnetic fabric of the Espinharas granite records the high-temperature deformation observed in the Seridó Belt. This deformation was active during a prolonged time range (~ 100 Ma) in a hybrid magmatic chamber emplaced in the middle- to shallow continental crust. These conditions indicate that the Patos shear zone controlled the development of the magmatic- to solid-state fabric of the Espinharas granite, highlighting the contribution of strain partitioning in the mechanical mingling of magmas in the continental crust.

Simulated Extreme Prepitation Indices over Northeast Brasil in Current Climate and Future Scenarios RCP4.5 and RCP8.5  

NASA Astrophysics Data System (ADS)

In this study, we analyzed extreme precipitation indices, for present and future modeled climates over Northeast of Brazil (NEB), from CORDEX simulations over the domain of Tropical Americas. The period for the model validation was from 1989-2007, using data from the European Center (ECWMF) Reanalysis, ERA-INTERIM, as input to drive the regional model (RAMS 6.0). Reanalysis data were assimilated via both lateral boundaries and the entire domain (a much weaker "central nudging"). Six indices of extreme precipitation were calculated over NEB: the average number of days above 10, 20 and 30 mm in one year (R10, R20, R30), the number of consecutive dry days (CDD), the number of consecutive wet days (CWD) and the maximum rainfall in five consecutive days (RX5). Those indices were compared against two independent databases: MERRA (Modern Era Retrospective analysis for Research and Applications) and TRMM (Tropical Rainfall Measuring Mission). After validation, climate simulations were performed for the present climate (1985-2005) and short-term (2015-2035), mid-term (2045-2065) and long-term (2079 to 2099) future climates for two scenarios: RCP 4.5 and RCP 8.5, nesting RAMS into HadGEM2-ES global model (a participant of CMIP5). Along with the indices, we also calculated Probability Distribution Functions (PDFs) to study the behavior of daily precipitation in the present and by the end of the 21st century (2079 to 2099) to assess possible changes under RCPs 4.5 and 8.5. The regional model is capable of representing relatively well the extreme precipitation indices for current climate, but there is some difficulties in performing a proper validation since the observed databases disagree significantly. Future projections show significant changes in most extreme indices. Rnn generally tend to increase, especially under RCP8.5. More significant changes are projected for the long-term period, under RCP8.5, which shows a pronounced R30 enhancement over northern states. CDD tends to decrease over most of NEB in the short but this trend is reverted toward the end of the century in both scenarios with a significant increase in the duration of the dry season over Northwestern and Eastern NEB (exceeding 50 days over certain areas), whereas projected CWD changes are smaller. Rx5 shows a general increasing trend especially in the long term period,under RCP8.5.

Performance of a multi-disciplinary emergency department observation protocol for acetaminophen overdose.  


The availability of 20-h N-acetylcysteine (NAC) infusion for low-risk acetaminophen (APAP) overdose enabled our center to implement an Emergency Department observation unit (OU) protocol as an alternative to hospitalization. Our objective was to evaluate our early experience with this protocol. This retrospective cohort study included all patients treated for low-risk APAP overdose in our academic hospital between 2006 and 2011. Cases were identified using OU and pharmacy records. Successful OU discharge was defined as disposition with no inpatient admission. Differences in medians with 95 % confidence intervals were used for comparisons. One hundred ninety-six patients received NAC for APAP overdose with a mean age of 35 years (SD 14); 73 % were white, and 43 % were male. Twenty (10 %) received care in the OU; 3/20(15 %) met criteria for inclusion in the OU protocol and 13/20(65 %) were discharged successfully. Out of the 196 patients, 10 met criteria for inclusion in the OU protocol but instead received care in the inpatient setting. The median total length of stay from presentation to ED discharge was 41 h for all patients treated in the OU, compared to 68 h for ten patients who met criteria for inclusion in the OU protocol but who were admitted (difference 27 h, 95 % CI 18-72 h). ED observation for APAP overdose can be a viable alternative to inpatient admission. Most patients were successfully discharged from the OU. This evaluation identified both over- and under-utilization of the OU. OU treatment resulted in shorter median length of stay than inpatient admission. PMID:23793935

The cave of Toca do Serrote do Artur (São Raimundo Nonato Archaeological Area, southeastern Piauí, Brazil) has yielded a Mammalian community constituted of Dasypus septemcinctus, Propraopus cf. sulcatus, Hoplophorus euphractus, Glyptodon clavipes, Conepatus sp., Panthera onca, Equus neogaeus, Dicotyles tajacu, Tayassu pecari, Palaeolama major, Mazama guazoubira, Mazama americana and a large Cervid. In comparison with the Mammalian fauna of the other sites from the same area, such a list shows a comparatively reduced biodiversity together with the presence of rare ( Hoplophorus, Conepatus) or unknown ( Propraopus, Palaeolama major) taxa. Explanation lies in the more recent age of the fossiliferous layers, probably Lower Holocene, as demonstrated by two 14C dating of 8 490 ± 120 BP and 6 890 ± 60 BP of the highest one. Moreover, that fauna shows the late survival of some genera ( Propraopus, Hoplophorus, Glyptodon, Equus, Palaeolama) together with climatic modifications related to the Pleistocene-Holocene transition.

La matiere noire dans l'Univers.  

NASA Astrophysics Data System (ADS)

Parmi les mille questions que l'on peut se poser sur l'Univers, les plus fondamentales concernent son contenu : De quoi est faite la matière de l'Univers ? Est-ce que la matière de l'Univers est principalement constituée d'étoiles, ou bien de gaz interstellaire, de poussières interstellaires, de planètes, petits astéroïdes, ou de trous noirs ? Ou doit-on admettre que l'Univers est composé d'une autre forme de matière que l'on ne connaît pas, qui serait basée sur des particules élémentaires plus exotiques que les protons, neutrons et électrons qui constituent la matière ordinaire, dite baryonique?

Superfund record of decision (EPA region 10): Fort Wainwright, Operable Unit 4, Fairbanks-North Star Borough, Fairbanks, AK, September 24, 1996  

SciTech Connect

This Record of Decision (ROD) presents the selected remedial actions for the Operable Unit 4 (OU-4) at Fort Wainwright in Fairbanks, Alaska. OU-4 comprises three source areas: the landfill, the Coal Storage Yard (CSY), and the Fire Training Pits (FTPs). Specific groundwater contaminants of concern at the landfill include benzene; 1,1,2-trichloroethane; 1,1,2,2-tetrachloroethane; bis(2-ethylhexyl)phthalate; cis-1,2 dichloroethene; and trichloroethene (TCE). Groundwater contaminants at the CSY include TCE; bis(2-ethylhexyl)phthalate; toluene; and benzene. The ROD addresses soil and groundwater contamination at OU-4.

The Morris-Lecar neuron model embeds a leaky integrate-and-fire model.  


We show that the stochastic Morris-Lecar neuron, in a neighborhood of its stable point, can be approximated by a two-dimensional Ornstein-Uhlenbeck (OU) modulation of a constant circular motion. The associated radial OU process is an example of a leaky integrate-and-fire (LIF) model prior to firing. A new model constructed from a radial OU process together with a simple firing mechanism based on detailed Morris-Lecar firing statistics reproduces the Morris-Lecar Interspike Interval (ISI) distribution, and has the computational advantages of a LIF. The result justifies the large amount of attention paid to the LIF models. PMID:22623224

Prospective Randomized Comparison of Open versus Transperitoneal Laparoscopic Ureterolithotomy: Experience of a Single Center from Northern India  

PubMed Central

Aim Prospective randomized study on transperitoneal laparoscopic ureterolithotomy (TPLU) versus open ureterolithotomy (OU) for treatment of large impacted ureteric stones (? 1.5 cm) and assessment of overall results. Material & Methods In a prospective study between 2010 to 2012, 30 patients underwent TPLU and 30 OU based on 1:1 randomization. The operation was indicated primarily in 44 cases or after failed shock-wave lithotripsy/ureteroscopy in 16 cases. Two groups were compared for operative time, success rate, visual pain score, analgesic requirement, hospital stay, and postoperative complications. Statistical analysis was performed with SPSS® version 16.0 using Fisher exact or Mann-Whitney U tests with p < 0.05 considered statistically significant. Results The difference in visual pain score (6.2 in TPLU group vs 3.1 in OU group on day 1; 4.8 vs. 2.4 on day 2) and tramadol requirements (184.32 mg in TPLU group vs. 150.87 mg in OU group on day 1; 97.34 mg vs. 65.56 mg on day 2) were statistically significant and more in OU. Hospital stay and convalescence were significantly lower in the TPLU. However, stone removal in one attempt was similar in both the groups. Conclusion Although successful stone removal rates are equal in both groups, TPLU is associated significantly with less postoperative pain, less analgesic requirement, shorter hospital stay and short convalescence in comparison to OU.
