Foraminotomia cervical posterior en el tratamiento de conflictos foraminales  

PubMed Central

Introduccin: La foraminomotima cervical posterior es un procedimiento utilizado para la descompresion radicular por via posterior y constituye una alternativa a la via clsica anterior. En este trabajo evaluamos nuestra serie de pacientes tratados por esta via. Mtodo: Desde enero de 2008 a diciembre de 2011, 17 pacientes (18 foraminotomas) fueron operados por presentar cervicobraquialgia a causa de un conflicto foraminal, realizando un foraminotoma cervical posterior. Los pacientes fueron evaluados en el postoperatorio inmediato, al mes y a los 3 meses de la ciruga. Los parmetros para valorar los resultados fueron la Escala Anloga del Dolor (VAS), la Neck Disability Index y los criterios de Odom. Resultados: El dolor radicular por conflicto foraminal secundario a hernia de disco cervical fue el sntoma y la patologa predominante. El nivel ms afectado fue C5-C6. La resolucin completa del dolor radicular se observ en casi todos los pacientes. La VAS preoperatoria en promedio fue de 8.8 (mnimo 8 mximo 10), con una franca mejora en todos los casos (0.4 en el ltimo control). La media en la Neck Disability Index al inicio fue de 35.3 (mnimo 32 mximo 45), con una evolucin favorable en la evaluacin final (0.6). Los Criterios de Odom para la evaluacin de pacientes operados de columna cervical fueron satisfactorios con un promedio de 1.17. Se observaron complicaciones en 4 pacientes (23%), todas tuvieron una evolucin favorable. No hubo infecciones, discitis ni empeoramiento de los sntomas preexistentes en ningn paciente. Conclusin: La foraminotoma cervical posterior es un procedimiento efectivo para el tratamiento del dolor radicular en los conflictos foraminales PMID:23596556

Resumen El uso del diagnstico rpido para HIV en Argentina, as como otros pases de Latinoamrica, ha sido limitado hasta el momento. Este trabajo reporta los resultados provenientes de un estudio cualitativo realizado entre hombres gays y otros hombres que tienen sexo con hombres (G&HSH) de la Ciudad de Buenos Aires, Argentina. El objetivo principal del mismo fue conocer las ventajas y desventajas que los hombres G&HSH perciben en relacin al diagnstico rpido casero para HIV. Se realizaron ocho grupos focales con 73 participantes en los cuales se discuti acerca de las ventajas y desventajas del uso de los diagnsticos rpidos. Las respuestas fueron codificadas utilizando un programa para anlisis de datos cualitativos (NVivo) y analizadas temticamente. Los participantes describieron numerosas ventajas sobre el uso del diagnstico rpido casero, aunque algunos reportaron importantes preocupaciones dentro de las cuales se destaca la posibilidad de impulsos suicidas si alguien recibe un resultado positivo estando solo. En trminos generales se observ una gran aceptabilidad para el uso del diagnstico rpido si el mismo es realizado por personal de salud en lugares acondicionados para este fin. PMID:25284951

International Space Station USOS Waste and Hygiene Compartment Development  

NASA Technical Reports Server (NTRS)

The International Space Station (ISS) currently provides human waste collection and hygiene facilities in the Russian Segment Service Module (SM) which supports a three person crew. Additional hardware is planned for the United States Operational Segment (USOS) to support expansion of the crew to six person capability. The additional hardware will be integrated in an ISS standard equipment rack structure that was planned to be installed in the Node 3 element; however, the ISS Program Office recently directed implementation of the rack, or Waste and Hygiene Compartment (WHC), into the U.S. Laboratory element to provide early operational capability. In this configuration, preserved urine from the WHC waste collection system can be processed by the Urine Processor Assembly (UPA) in either the U.S. Lab or Node 3 to recover water for crew consumption or oxygen production. The human waste collection hardware is derived from the Service Module system and is provided by RSC-Energia. This paper describes the concepts, design, and integration of the WHC waste collection hardware into the USOS including integration with U.S. Lab and Node 3 systems.

Compilao de dados atmicos e moleculares do UV ao IV prximo para uso em sntese espectral  

NASA Astrophysics Data System (ADS)

Espectros sintticos so utis em uma grande variedade de aplicaes, desde anlise de abundncias em espectros estelares de alta resoluo ao estudo de populaes estelares em espectros integrados. A confiabilidade de um espectro sinttico depende do modelo de atmosfera adotado, do cdigo de formao de linhas e da qualidade dos dados atmicos e moleculares que so determinantes no clculo das opacidades da fotosfera. O nosso grupo no departamento de Astronomia no IAG tem utilizado espectros sintticos h mais de 15 anos, em aplicaes voltadas principalmente para a anlise de abundncias de estrelas G, K e M e populaes estelares velhas. Ao longo desse tempo, as listas de linhas vieram sendo construdas e atualizadas continuamente, e alguns acrscimos recentes podem ser citados: Castilho (1999, tomos e molculas no UV), Schiavon (1998, bandas moleculares de TiO) e Melendez (2001, tomos e molculas no IV prximo). Com o intuito de calcular uma grade de espectros do UV ao IV prximo para uso no estudo de populaes estelares velhas, se fazia necessrio compilar e homogeneizar as diversas listas em apenas uma lista atmica e uma molecular. Nesse processo, a nova lista compilada foi correlacionada com outras bases de dados (NIST, Kurucz Database, O' Brian et al. 1991) para atualizao dos parmetros que caracterizam a transio atmica (comprimento de onda, log gf e potencial de excitao). Adicionalmente as constantes de interao C6 foram calculadas segundo a teoria de Anstee & O'Mara (1995) e artigos posteriores. As bandas moleculares de CH e CN foram recalculadas com o programa LIFBASE (Luque & Crosley 1999). Nesse poster esto detalhados os procedimentos citados acima, as comparaes entre espectros calculados com as novas listas e espectros observados em alta resoluo do Sol e de Arcturus, e uma anlise do impacto decorrente da utilizao de diferentes modelos de atmosfera no espectro sinttico. Ao final, temos uma lista de linhas atmicas com mais de 24.000 linhas e uma lista molecular com as molculas CN, CH, OH, NH, MgH, C2, TiO Gama, CO, FeH, adequadas ao estudo de estrelas G, K e M e populaes estelares velhas.

International Space Station USOS Potable Water Dispenser Development  

NASA Technical Reports Server (NTRS)

The International Space Station (ISS) Russian Segment currently provides potable water dispensing capability for crewmember food and beverage rehydration. All ISS crewmembers rehydrate Russian and U.S. style food packages from this location. A new United States On-orbit Segment (USOS) Potable Water Dispenser (PWD) is under development. This unit will provide additional potable water dispensing capability to support an onorbit crew of six. The PWD is designed to provide incremental quantities of hot and ambient temperature potable water to U.S. style food packages. It will receive iodinated water from the Fuel Cell Water Bus in the U.S. Laboratory element. The unit will provide potable-quality water, including active removal of biocidal iodine prior to dispensing. A heater assembly contained within the unit will be able to supply up to 2.0 liters of hot water (65 to 93oC) every thirty minutes. This quantity will allow three to four crewmembers to rehydrate their food and beverages from this location during a single meal. The unit is designed to remain functional for up to ten years with replacement of limited life items such as filters. It will be the size of two stacked Shuttle Middeck lockers (approximately the size of two small suitcases) and integrated into a science payload rack in the U.S. Laboratory element. Providing potable-quality water at the proper temperature for food and beverage reconstitution is critical to maintaining crew health and well-being. The numerous engineering challenges as well as human factors and safety considerations during the concept, design, and prototyping are outlined in this paper.

Relaxing USOS Solar Array Constraints for Russian Vehicle Undocking  

NASA Technical Reports Server (NTRS)

With the retirement of Space Shuttle cargo delivery capability and the ten year life extension of the International Space Station (ISS) more emphasis is being put on preservation of the service life of ISS critical components. Current restrictions on the United States Orbital Segment (USOS) Solar Array (SA) positioning during Russian Vehicle (RV) departure from ISS nadir and zenith ports cause SA to be positioned in the plume field of Service Module thrusters and lead to degradation of SAs as well as potential damage to Sun tracking Beta Gimbal Assemblies (BGA). These restrictions are imposed because of the single fault tolerant RV Motion Control System (MCS), which does not meet ISS Safety requirements for catastrophic hazards and dictates 16 degree Solar Array Rotary Joint position, which ensures that ISS and RV relative motion post separation, does lead to collision. The purpose of this paper is to describe a methodology and the analysis that was performed to determine relative motion trajectories of the ISS and separating RV for nominal and contingency cases. Analysis was performed in three phases that included ISS free drift prior to Visiting Vehicle separation, ISS and Visiting Vehicle relative motion analysis and clearance analysis. First, the ISS free drift analysis determined the worst case attitude and attitude rate excursions prior to RV separation based on a series of different configurations and mass properties. Next, the relative motion analysis calculated the separation trajectories while varying the initial conditions, such as docking mechanism performance, Visiting Vehicle MCS failure, departure port location, ISS attitude and attitude rates at the time of separation, etc. The analysis employed both orbital mechanics and rigid body rotation calculations while accounting for various atmospheric conditions and gravity gradient effects. The resulting relative motion trajectories were then used to determine the worst case separation envelopes during the clearance analysis. Analytical models were developed individually for each stage and the results were used to build initial conditions for the following stages. In addition to the analysis approach, this paper also discusses the analysis results, showing worst case relative motion envelopes, the recommendations for ISS appendage positioning and the suggested approach for future analyses.

International Space Station USOS Potable Water Dispenser On-Orbit Functionality Versus Design  

NASA Technical Reports Server (NTRS)

The International Space Station (ISS) currently provides potable water dispensing for rehydrating crewmember food and drinking packages. There is one system located in the United States On-orbit Segment (USOS) and one system in the Russian Segment. Shuttle mission STS-126 delivered the USOS Potable Water Dispenser (PWD) to ISS on ULF2; subsequent activation occurred on November 2008. The PWD is capable of supporting an ISS crew of six, but nominally supplies only half this crew size. The PWD design provides incremental quantities of hot and ambient temperature potable water to US food and beverage packages. PWD receives iodinated water from the US Water Recovery System (WRS) Fuel Cell Water Bus, which feeds from the Water Processing Assembly (WPA). The PWD removes the biocidal iodine to make the water potable prior to dispensing. A heater assembly contained within the unit supplies up to 2.0 L of hot water (65 to 93 ?C) every 30 min. During a single meal, this quantity of water supports three to four crewmembers? food rehydration and beverages. The unit design has a functional life expectancy of 10 years, with replacement of limited life items, such as filters. To date, the PWD on-orbit performance is acceptable. Since activation of the PWD, there were several differences between on-orbit functionality and expected performance of hardware design. The comparison of on-orbit functionality to performance of hardware design is discussed for the following key areas: 1) microbial contamination, 2) no-dispense and water leakage scenarios, and 3) under-dispense scenarios.

International Space Station USOS Crew Quarters Ventilation and Acoustic Design Implementation  

NASA Technical Reports Server (NTRS)

The International Space Station (ISS) United States Operational Segment (USOS) has four permanent rack sized ISS Crew Quarters (CQ) providing a private crewmember space. The CQ uses Node 2 cabin air for ventilation/thermal cooling, as opposed to conditioned ducted air from the ISS Temperature Humidity Control System or the ISS fluid cooling loop connections. Consequently, CQ can only increase the air flow rate to reduce the temperature delta between the cabin and the CQ interior. However, increasing airflow causes increased acoustic noise so efficient airflow distribution is an important design parameter. The CQ utilized a two fan push-pull configuration to ensure fresh air at the crewmember s head position and reduce acoustic exposure. The CQ interior needs to be below Noise Curve 40 (NC-40). The CQ ventilation ducts are open to the significantly louder Node 2 cabin aisle way which required significantly acoustic mitigation controls. The design implementation of the CQ ventilation system and acoustic mitigation are very inter-related and require consideration of crew comfort balanced with use of interior habitable volume, accommodation of fan failures, and possible crew uses that impact ventilation and acoustic performance. This paper illustrates the types of model analysis, assumptions, vehicle interactions, and trade-offs required for CQ ventilation and acoustics. Additionally, on-orbit ventilation system performance and initial crew feedback is presented. This approach is applicable to any private enclosed space that the crew will occupy.

Relation entre les caractristiques des table-bancs et les mesures anthropomtriques des coliers au Benin

Introduction Le mobilier scolaire et la posture assise en classe sont souvent impliqus dans l'apparition des douleurs rachidiennes, influant de fait sur la qualit des tches ralises par les apprenants. Aucune tude n'a encore vrifi le degr d'adquation entre les caractristiques du mobilier et celles des coliers au Bnin. L'objectif de cette tude transversale est donc de dterminer la relation entre les dimensions des table-bancs utilises en classe et les mesures anthropomtriques des coliers au Bnin. Methods Elle a t ralise avec un chantillon probabiliste de 678 coliers, gs de 4 17 ans. Les mesures anthropomtriques des coliers et les mensurations relatives aux longueurs, largeurs et hauteurs des table-bancs ont t mesures, puis intgres aux quations proposes dans la littrature. Les pourcentages des valeurs situes hors des limitesacceptables, drives de l'application des quations ont t calculs. Results La largeur et la hauteur des table-bancs utilises par les coliers taient plus leves (p < 0,05) que les valeurs de rfrence recommandes par les structures officielles de contrle et de production des mobiliers scolaires au Bnin. Quel que soit le sexe, il y avait une inadquation entre la largeur du banc et la longueur fesse-poplit, puis entre la hauteur de la table et la distance coude-bancdes coliers. Conclusion Les rsultats suggrent de prendre en compte lvolution des mesures anthropomtriques des coliers dans la confection des table-bancs, afin de promouvoir de bonnes postures assises en classe et de rduire le risque de troubles du rachis.

[Phlebotominae: vectors of leishmaniasis in the provinces of Santa Fe and Entre Ros, Argentina].  

PubMed

The transmission of tegumentary leishmaniasis (TL) has increased in 9 provinces of Argentina since 1985. Santa Fe and Entre Ros did not record in this period autochtonous probed cases: however, an epidemic outbreak took place in 2003 in Bella Vista, Corrientes, located in an area with ecological continuity and contiguous to both provinces. In order to evaluate the potential risk of transmission of LT, Phlebotominae were captured at locations close to and southern from Bella Vista during February 2004. The traps located on the shores of Parana river in Santa Fe (El Rabn, Villa Ocampo, Cayast), and Entre Ros (La Paz. La Celina-Villa Urquiza) captured 860 individuals of Lutzomyia neivai (99.5%) and Lu. migonei (0.5 %), both species with vectorial capacity for Leishmania (V.) braziliensis. In Tartagal, Santa Fe, the captures were consistent with the residual "chaco" landscape, 7 individuals of Lu. nerivai, Lu. migonei and Lu. cortelezzii.

Alternaria alternata prevalence in cereal grains and soybean seeds from Entre Ros, Argentina.  

PubMed

A mycological survey was carried out at Entre Ros province, Argentina, on sorghum grain, maize, rice, soybean seeds and on freshly harvested and stored wheat. The isolation frequencies and relative densities of species belonging to genera Alternaria, Aspergillus, Fusarium, Penicillium and other fungi were calculated. Alternaria alternata was the major fungal species isolated from sorghum, rice, soybean seeds and on freshly harvested wheat, and a low incidence of Fusarium species was observed on the same substrates. In maize the major fungal species isolated was Fusarium verticillioides. The high incidence levels of A. alternata observed,suggest that it may be necessary to determine, among other mycotoxins, if Alternaria toxins occur in these commodities. PMID:17592893

Thermal analysis, differential scanning calorimetry, and X-ray diffraction were carried out to study the polymorphism and pseudopolymorphism of lorazepam and oxazepam. Two polymorphic forms of lorazepam and several mono- or hemisolvates were obtained after recrystallization from various solvents. No polymorphic form or solvate has been found for oxazepam. The crystallographic parameters of these new phases were determined. Lorazepam and oxazepam can lose a molecule of water at 160 and 203C, respectively, and rearrange to quinazolinecarboxaldehyde. Mixed crystals of the two benzodiazepines, after recrystallization from benzene, lead to molecular alloys with complete solid solubility between oxazepam and the ?-form of lorazepam over the whole range of composition but only to partial solubility with the ?-form of lorazepam.

The effect of coordinated water on the connectivity of uranium(IV) sulfate x-hydrate: [U(SO4)2(H2O)5]H2O and [U(SO4)2(H2O)6]2H2O, and a comparison with other known structures.  

PubMed

Two new solid-state uranium(IV) sulfate x-hydrate complexes (where x is the total number of coordinated plus solvent waters), namely catena-poly[[pentaaquauranium(IV)]-di-?-sulfato-?(4)O:O'] monohydrate], {[U(SO4)2(H2O)5]H2O}n, and hexaaquabis(sulfato-?(2)O,O')uranium(IV) dihydrate, [U(SO4)2(H2O)6]2H2O, have been synthesized, structurally characterized by single-crystal X-ray diffraction and analyzed by vibrational (IR and Raman) spectroscopy. By comparing these structures with those of four other known uranium(IV) sulfate x-hydrates, the effect of additional coordinated water molecules on their structures has been elucidated. As the number of coordinated water molecules increases, the sulfate bonds are displaced, thus changing the binding mode of the sulfate ligands to the uranium centre. As a result, uranium(IV) sulfate x-hydrate changes from being fully crosslinked in three dimensions in the anhydrous compound, through sheet and chain linking in the tetra- and hexahydrates, to fully unlinked molecules in the octa- and nonahydrates. It can be concluded that coordinated waters play an important role in determining the structure and connectivity of U(IV) sulfate complexes. PMID:24992121

NASA Astrophysics Data System (ADS)

Comparison of the characteristics of an electric are breakdown in vacuum between two silver or silver-nickel alloy electrodes prompted us to study the evolution of the breakdown voltage with electrode separation, with resistance value placed between the anode and the high voltage supply used for the breakdown, and with the effect of conditionning by heating in vacuum. The measurement of the commutation time and delay time, and the observations by a metallographic microscope of the electrodes surfaces after one breakdown, enabled us to evidence the origin of the electric arc for each of the studied materials. La comparaison des caractristiques de l'amorage d'un arc lectrique dans le vide entre deux lectrodes bombes de 8mm de diamtre et de rayon de courbure en surface de 16mm, constitues d'argent ou de son alliage avec le nickel, nous a amen tudier l'volution de la tension d'amorage avec plusieurs paramtres : la distance inter-lectrodes, les valeurs de la rsistance intercale entre la source haute tension servant au claquage et les lectrodes et le conditionnement par chauffage sous vide des lectrodes.

Desarrollo de la Escala sobre el Estigma Relacionado con el VIH/SIDA para Profesionales de la Salud mediante el uso de mtodos mixtos123  

PubMed Central

El estigma relacionado con el VIH/SIDA contina siendo un obstculo para la prevencin primaria y secundaria del VIH. Las consecuencias para las personas que viven con la enfermedad han sido muy documentadas y continan siendo una gran preocupacin para las personas que proveen servicios de salud y para aquellas que investigan el tema. Estas consecuencias son preocupantes cuando el estigma emana de profesionales de la salud porque se puede limitar el acceso a los servicios. Uno de los principales obstculos para la investigacin del estigma relacionado con el VIH en Puerto Rico es la falta de instrumentos cuantitativos para evaluar las manifestaciones del estigma entre profesionales de la salud. El objetivo principal de este estudio fue desarrollar y probar las propiedades psicomtricas de una escala sobre el estigma relacionado con el VIH/SIDA culturalmente apropiada para personas que proveen servicios de salud puertorriqueas y desarrollar una versin corta de la escala que pudiera usarse en escenarios clnicos con tiempo limitado. El instrumento desarrollado estuvo basado en evidencia cualitativa recopilada entre profesionales y estudiantes de profesiones de la salud puertorriqueos/as (n=80) y administrado a una muestra de 421 profesionales de la salud en adiestramiento. La escala contena 12 dimensiones del estigma relacionado con el VIH/SIDA. El anlisis cuantitativo corrobor 11 de ellas, teniendo como resultado un instrumento con validez y confiabilidad satisfactoria. Estas dimensiones, a su vez, fueron subcomponentes de un factor de estigma general superior. PMID:20333258

Soil Quality Indicators to Define Land Use in the Area of Native Forest of Entre Ros, Argentina  

NASA Astrophysics Data System (ADS)

The main economic activity in the area of native forest of the province of Entre Ros (Argentina) has long been the agricultural and/or livestock production, especially cattle breeding. In recent years, the proportion of agricultural crops in the rotations, especially that of soybean, has increased, thus leading to an increase in the need for land clearing to incorporate new lands for agricultural use. Most of these lands are considered marginal for agricultural use. In addition rice farming with irrigation is a critical part of the Entre Ros economy. Defining and assessing soil quality indicators (SQI) that show the evolution of the soil with different uses and management systems is a way to contribute to the knowledge of soil quality. The aims of this study were to characterize the current land use and land tenure in the area of native forest of Entre Ros, as well as to identify and select variables sensitive to agricultural and/or livestock use of the most representative soils of this area (indicators of the dynamic quality of the soil) and define the most appropriate land use according to land suitability and behavior of these indicators. We identified the most representative soil subgroups (corresponding to the orders Vertisols, Mollisols and Alfisols) and defined the production systems livestock-agricultural, agricultural-livestock, agricultural without irrigation, and rice crop irrigated with water from groundwater and surface reservoirs. We also determined the physical, physico-chemical, chemical and microbiological variables of the soil, and characterized the quality of the water for irrigation. We selected the SQI using Principal Components Analysis, to form a minimum data set (MDS). The change in the use of the land responded to a favorable economic situation for agriculture that started in the 1990's. The leasing and sharecropping schemes and the incidental contracts have become increasingly important, predominating over the undivided property. We obtained the MDS for twelve combinations of soil subgroups and production systems. The MDS for each of them presented between six and nine SQI. The indicators showed greater variation in the MDS by production system than by unit of land. Total organic carbon content (TOC) and the structural stability index (Is) were included in all the MDS. The rice systems showed high dependence on the quality of the irrigation water. We also found high fragility of some soil subgroups. The results suggest that rotations including pastures in a high proportion should be considered, especially in Alfisols and Vertisols. The native forest is considered as the basis of sustainable production systems for the study area. Thus, the land that has already been cleared or is about to be cleared should consider an agricultural and/or livestock use according to its productive capacity and its limitations.

Competition entre les phases ferromagnetique metallique et ordre de charges a l'interface de manganites a magnetoresistance colossale  

NASA Astrophysics Data System (ADS)

Dans la these qui suit, l'interaction entre deux manganites a magnetoresistance colossale domines par des phases antagonistes est etudiee a l'interface de bicouches. Un manganite isolant anti-ferromagnetique presentant une phase d'ordre de charges a basse temperature et un manganite metallique domine par les interactions ferromagnetiques. L'objectif est de verifier si l'interaction entre ces deux manganites est susceptible de soit 1) affaiblir la stabilite de l'ordre de charges ou soit 2) de rendre la phase metallique plus resistive afin d'ameliorer les proprietes de magnetoresistance colossale. Deux series de bicouches ont ete preparees par depot par ablation laser pulse et analysees avec une combinaison de plusieurs methodes experimentales telles que la mesure de resistance electrique, la spectroscopie Raman, la mesure d'aimantation et la diffraction des rayons X. Dans la premiere serie de bicouches, la configuration utilisee consiste en une couche tampon ferromagnetique sur laquelle une couche de manganite a ordre de charges est deposee. Il s'est avere que la phase d'ordre de charges n'est pas destabilisee par la phase ferromagnetique metallique dans une couche d'ordre de charges aussi mince que 10 nm. Les mesures de resistance montrent que la phase isolante demeure difficile a rendre metallique sous l'application d'un champ magnetique. La spectroscopie Raman montre egar lement une phase d'ordre de charges tres stable et suggere que les contraintes mecaniques appliquees par la couche tampon sont responsables de cette stabilite, malgre la presence de la phase ferromagnetique a proximite. Dans la deuxieme serie de bicouches, la configuration utilisee consiste en une couche tampon presentant de l'ordre de charges sur laquelle une couche ferromagnetique metallique est deposee. La diminution de l'epaisseur de la couche ferromagnetique metallique se repercute sur une diminution de la temperature de Curie et de la transition metal-isolant. Entre 4 et 5 nm, la transition metal-isolant est supprimee et la bicouche demeure isolante a toutes les temperatures. Dans la bicouche ayant une couche ferromagnetique de 4 nm, la transition metal-isolant est retrouvee sous l'application d'un champ magnetique de 1.5 T et une magnetoresistance de 50% est obtenue a 75K sous l'application d'un champ magnetique de 0.5 T. Un changement dans le champ magnetique necessaire a l'aimantation de la couche d'ordre de charges est egalement mesure, suggerant que la couche ferromagnetique induit des domaines ferromagnetiques dans la couche tampon. Ces resultats sont expliques par l'interaction mecanique dominant l'interface et favorisant la localisation des charges. L'anisotropie de la contrainte mecanique semble jouer un role supplementaire comparativement aux contraintes procurees par un substrat cubique. La rotation des octaedres ou la distorsion de Jahn-Teller, deux distorsions locales, pourraient contribuer a la tendance a localiser les charges. De plus, la phase isolante mesuree dans le Nd2/3Sr 1/3O3, normalement metallique, demeure plus sensible au champ magnetique que la phase isolante induite dans ce meme materiau par un substrat cubique isolant. La domination des contraintes mecaniques sur les influences ferromagnetiques suggere que cette influence soit le vecteur principal pour le controle de la separation de phases electroniques des manganites.

Magnetotellurics applied to the study of the Guaran aquifer in Entre Ros Province, N-E Argentina  

NASA Astrophysics Data System (ADS)

The South American Guaran Aquifer System covers the entire Parana basin and part of the Chaco-Parana basin. This system is one of the most important groundwater reservoirs; it is shared by four neighboring countries covering an area larger than one million square kilometers. The geological units closely related to the Guaran Aquifer are the Piramboia and Botucatu Formations that consist of Triassic-Jurassic aeolian, fluvial and lacustrine sandstones, and the Serra Geral basalts with clastic intercalations. Serra Geral, an effusive Cretaceous complex, covers the sandstones and provides a high degree of confinement to the system. This paper presents the interpretation of magnetotelluric (MT) data collected during 2007-2008 in Entre Ros Province, Argentina. These data, recorded in three profiles, mainly provide the depth to the crystalline basement, determinant for the presence of aquifer-related sediments. Models showed that the discrimination of the basalts strongly depends on local electrical characteristics. Model information is quite consistent with the information from oil and thermal wells located close to the profiles.

Etude des phenomenes chimiques au contact entre le bloc cathodique et la barre collectrice d'une cellule d'electrolyse d'aluminium  

NASA Astrophysics Data System (ADS)

La production d'aluminium est une industrie importante au Qubec. Les proprits de ce mtal le vouent de multiples usages prsents et futurs dans le cadre d'une conomie moderne durable. Toutefois, le procd Hall-Hroult est trs nergivore et des progrs demeurent donc ncessaires pour en diminuer les cots financiers et environnementaux. Parmi les amliorations envisageables de la cellule d'lectrolyse se trouve le contact entre la cathode et la barre collectrice, qui doit offrir une faible rsistivit au passage du courant lectrique. En cours d'opration de la cellule, ce contact a tendance se dgrader, gnrant des pertes nergtiques significatives. Les causes de cette dgradation, pouvant provenir de phnomnes chimiques, thermiques, mcaniques et/ou lectriques, demeurent mal comprises. Le but du prsent projet tait donc d'tudier les phnomnes chimiques se produisant au contact bloc-barre de la cellule d'lectrolyse Hall-Hroult. En premier lieu, un aspect crucial considrer est la pntration du bain lectrolytique dans la cathode, car des composs de bain atteignent ventuellement la barre collectrice et peuvent y ragir. A cet effet, une mthode novatrice a t dveloppe afin d'tudier les cathodes et la pntration du bain dans celles-ci l'aide de la microtomographie rayons X. Cette mthode rapide et efficace s'est avre fort utile dans le projet et a un potentiel important pour l'tude future des cathodes et des phnomnes qui s'y produisent. Ensuite, une cellule d'lectrolyse rectangulaire petite chelle a t dveloppe. Plusieurs phnomnes observs 'en industrie sur des autopsies de cellules post-opration et rapports dans la littrature ont t reproduis avec succs l'aide de cette cellule exprimentale. Puis, des tests sans lectrolyse, ciblant l'effet du bain lectrolytique sur l'acier, ont aussi t conus et complts afin de sgrger l'influence des diffrents paramtres en jeu. L'analyse des rsultats de l'ensemble de ces tests a permis de constater diffrents phnomnes au contact bloc-barre, dont la prsence systmatique de NaF et, surtout, de ?-Al 2O3. Outre la carburation invitable de la barre collectrice, la formation d'une couche Fe-Al a aussi t observe, favorise par une pntration rapide du bain lectrolytique dans la cathode ainsi que par une composition de bain acide en surface de la barre. Cette couche comportait par ailleurs des cristaux de ?-Al 2O3 pouvant nuire sa conductivit lectrique. Ensuite, des ratios de bain entre 2.5 et 4.9, une mince couche contenant les lments Al et N peut se former en surface de la barre. Pour un bain trs basique (> 6.0), c'est plutt une couche Na 2O qui a t observe. En conditions d'lectrolyse mais sans une pntration rapide du bain dans la cathode, du Na a pu carrment pntrer dans la barre collectrice, prfrentiellement avec le carbone. De plus, de la corrosion ainsi que des couches de fer et d'oxyde de fer peuvent se former sur la barre et potentiellement dgrader la qualit du contact lectrique. Pour la suite des travaux, des mesures de rsistivit ainsi que l'analyse des chantillons industriels permettraient d'valuer l'impact de ces phnomnes sur la qualit du contact. Mots-cls : lectrolyse, aluminium, Hall-Hroult, interface barre-cathode, bain lectrolytique.

Competition entre supraconductivite et magnetisme au voisinage de la transition de Mott dans le conducteur organique quasi-bidimensionnel k-(BEDT-TTF)2copper[N(CN)2]bromine  

NASA Astrophysics Data System (ADS)

Les conducteurs organiques quasi-bidimensionnels kappa-ET2X presentent d'importantes similitudes avec les SCHT telles qu'une phase isolant de Mott, un regime de pseudogap et un etat supraconducteur. L'etude de leurs proprietes apparait donc complementaire. Parmi les interrogations persistantes concernant la physique de ces systemes, l'origine du (ou des) processus exotique d'appariement, responsable de la supraconductivite est le sujet suscitant l'interet le plus marque dans la communaute. L'hypothese d'un mecanisme lie a la proximite d'un etat antiferromagnetique est privilegiee. Une etape importante dans la resolution de cette problematique est l'identification de la symetrie du parametre d'ordre. D'apres de nombreux travaux sur les systemes fortement correles, la sonde ultrasonore, de par sa sensibilite aux excitations de quasiparticule a basse temperature, est consideree comme particulierement adaptee a l'etude de cette propriete. Cependant, son emploi necessite l'utilisation d'un compose metallique a basse temperature et completement supraconducteur. Le compose metallique organique kappa-ET 2Cu[N(CN)2]Br presente toutes les caracteristiques necessaires a l'etude de cette propriete. En effet, il est situe loin de la transition du premier ordre de Mott et est completement supraconducteur. De facon surprenante, ce systeme semble se coupler fortement avec le reseau ce qui augmente significativement la sensibilite de cette sonde aux proprietes du gaz electronique. Cependant, des difficultes techniques importantes, liees a la nature intrinseque de ce materiau, doivent etre surmontees pour proceder a des mesures suivant differentes polarisations. La presente etude a profondement modifie notre comprehension de ce systeme. En effet, ces mesures ont permis de constater que le kappa-ET2Cu[N(CN)2]Br est un compose qui est situe en bordure de la zone de coexistence entre la supraconductivite et le magnetisme, ce qui constitue un resultat totalement inattendu. De plus, la variation judicieuse du cycle thermique s'est averee etre equivalente a une modification de la pression chimique. Cette derniere est modifiee par l'intermediaire d'une relaxation structurale autour de 85 K appelee la transition de verre d'ethylenes. Cela nous a permis de suivre l'evolution de cette coexistence en s'approchant de la transition de premier ordre, et ainsi de statuer sur la competition entre la supraconductivite et le magnetisme ainsi que sur l'existence d'une separation de phase d'ordre macroscopique. De plus, nous avons observe une anisotropie similaire sur les mesures de vitesse ultrasonore entre le regime de pseudogap et la supraconductivite. Ce resultat tend a confirmer l'existence d'une physique commune entre le regime de pseudogap et l'etat supraconducteur. Le regime de pseudogap, encore meconnu a ce jour, est probablement relie a des fluctuations antiferromagnetiques, dont l'origine pourrait etre un emboitement de la surface de Fermi quasi-unidimensionnelle de ce compose, ou bien relie a la proximite de la physique de Mott. Enfin, l'analyse de la symetrie du parametre d'ordre supraconducteur, qui est probablement de type s+d, tend a demontrer que les processus de couplage interplan sont d'une importance cruciale. L'approche theorique de Hubbard purement 2D dans le plan conducteur semble donc insuffisante pour la recherche du mecanisme d'appariement.

El uso de la neuromodulacin para el tratamiento del temblor  

PubMed Central

Introduccin: El temblor puede ser un desorden incapacitante y el tratamiento de primera lnea para estos pacientes es farmacolgico. Sin embargo, este tratamiento puede llevar a una reduccin satisfactoria del temblor en slo el 50% de los pacientes con temblor esencial. La talamotoma era el tratamiento de eleccin para el temblor refractario al tratamiento mdico hasta que comenz a utilizarse la estimulacin cerebral profunda (ECP) del ncleo ventral intermedio (Vim) del tlamo. En la actualidad, raramente se realiza la talamotoma. Mtodos: Este artculo es una revisin no sistemtica de las indicaciones, resultados, parmetros de programacin y tcnica quirrgica de la ECP del Vim para el tratamiento del temblor. Resultados: Aunque los resultados clnicos son similares usando la talamotoma o la ECP del Vim, la primera causa ms efectos adversos que la ltima. Adems, la ECP puede ser usada bilateralmente, mientras que la talamotoma tiene un alto riesgo de causar disartria cuando se realiza de ambos lados. La ECP del Vim logr una adecuada mejora del temblor en varias series de pacientes con temblor causado por temblor esencial, enfermedad de Parkinson o esclerosis mltiple. Adems del Vim, hay otros blancos que estn siendo usados por varios autores, tales como la zona incerta y las radiaciones prelemniscales. Conclusin: La ECP del Vim es un tratamiento til para el temblor incapacitante refractario al tratamiento mdico. Es esencial realizar una precisa seleccin de pacientes, as como utilizar una tcnica quirrgica correcta. An se desconoce el mejor blanco estereotctico para el temblor, aunque el Vim es el ms usado.

Vinculacin Fsica entre Super Cscaras de Hidrgeno Neutro y Formacin Estelar Reciente  

NASA Astrophysics Data System (ADS)

Many of the known galactic HI supershells (SCHI) may have been formed by the combined effects of stellar winds and supernovae explotions. Having most of them dynamic lifetimes of a few times 10^7 yr, these huge structures are likely to outlive the stars that gave rise to them. Hence, these SCHI may be used as fossil records of the Milky Way star formation history. Furthermore, along their evolution SCHI may trigger star formation. In this paper we analyze the genetic link put forward by McClure-Griffiths et al. (2002) between the OB association Cen OB1 and the SCHI GSH305+01-24. From our study we conclude that GSH305+01-24 may not represent a real physical structure. Instead, we believe that this structure is best represented by two unrelated huge HI shells. The role played by Cen OB1 in powering one of these HI shells is unclear for the time being. FULL TEXT IN SPANISH.

Relacin fsica entre el cmulo abierto Hogg 15 y la estrella Wolf-Rayet WR 47  

NASA Astrophysics Data System (ADS)

We revise the fundamental parameters of the faint open cluster Hogg 15, for which two recent colour-magnitude diagram (CMD) studies have obtained significantly different ages (Sagar et al. 2001, MNRAS, 327, 23; Piatti & Clari 2001, A&A, 370, 931). In the present study, we combine a series of methods trying to constrain age, together with other fundamental parameters. We employ spatial extractions to construct the CMDs, and the cluster integrated spectrum to compare the latter with those of templates of known age. For Hogg 15 we derive an age of (20 10) Myr, a reddening of (1.10 0.05) mag, and a distance of (3.1 0.5) kpc. We conclude that the estimation of an older age in the study of Piatti & Clari can be accounted for in terms of main sequence/turnoff curvature being blurred in the CMDs, an effect mainly caused by field contamination. To clarify the issue of whether the Wolf-Rayet star HDE 311884 (WR 47), known to be a WN6 + O5V binary system, is associated or not with Hogg 15, we discuss its fundamental parameters, particularly its distance. Based on the WR 47 spectrum and available photometry, we assume that the underestimated distance implied by the Hipparcos parallax (216 pc) is affected by its binary character. By comparing the WR 47 spectrum with those of WR stars of a similar type, we conclude that WR 47 is not affected by a E(B-V) colour excess much higher than that associated with Hogg 15, namely E(B-V) = 1.10. On the basis of the WR 47's resulting distance of (5.2 0.9) kpc, which largely surpasses that of the cluster, we conclude that WR 47 is not related to Hogg 15 from the point of view of origin, since the cluster and the star do not belong to the same formation event.

Calculs Numeriques des Interactions Entre les Champs Electromagnetiques et les Tissus Biologiques  

NASA Astrophysics Data System (ADS)

The understanding of electromagnetic field effects on health is a very acute problem nowadays. Indeed, the daily landscape is invaded by waves generated by affordable state-of-the-art equipment. It becomes urgent to improve the knowledge in order to ensure the safety of the users and the general public. At high frequencies two areas of concern can be distinguished: cellular telephony and wireless indoor communications. This dissertation is devoted to two aspects of the research in this field i.e. the numerical dosimetry and the biological experimentation. A new formulation for an expanding grid algorithm based upon the FDTD that can be applied, in particular, at high frequencies is presented. The energy deposition and the associated temperature rise in a model of the human eye due to a resonant dipole at frequencies of 840, 915, 1500 and 1800 MHz are then calculated. The duty cycle of each system is then introduced and its impact on temperature elevation is examined. Finally, a methodological approach to standard setting for portable transceivers is proposed. On the experimental aspect, a protocol has been elaborated and an experimentation to study athermal effects of electromagnetic fields at 9.3 GHz has been carried out. In particular, the importance of polarization has been examined.

Estrategia innovadora enfocada en parejas del mismo sexo para disminuir la infeccin del VIH en hombres Latinos  

PubMed Central

Resumen El VIH es un problema de salud importante dentro de la comunidad latina de los Estados Unidos. Gracias a los esfuerzos de prevencin, los niveles de contagio entre los latinos se han mantenido estables por ms de una dcada. Sin embargo, esta poblacin sigue siendo afectada a niveles muy altos, en particular entre hombres que tienen sexo con hombres (HSH), de origen latino y que hablan principalmente el idioma espaol. Existen varios factores que contribuyen a la transmisin del VIH entre esta poblacin, como son: el uso de drogas; la violencia dentro de la pareja; la presencia de infecciones de transmisin sexual; relaciones sexuales sin proteccin, dentro y fuera de la pareja; el evadir la bsqueda de recursos (prueba y tratamiento adecuado) por temor a ser discriminado o por su estatus migratorio; la escasez de recursos econmicos o estado de pobreza y los patrones relacionados a la migracin. En particular, Investigaciones Epidemiolgicas de Comportamientos han determinado: cmo algunas dinmicas en parejas estn directamente asociadas a los comportamientos sexuales de riesgos. En consecuencia, es necesaria mayor investigacin para identificar esas dinmicas, y a su vez, realizar intervenciones dirigidas a la reduccin de conductas de riesgo enfocadas en parejas de hombres del mismo sexo. En este escrito, se describe la importancia del uso de las relaciones de pareja como estrategia en la reduccin de la trasmisin del VIH/SIDA en HSH de origen latino y que hablan principalmente el idioma espaol en los Estados Unidos.

El inters por comprender la co-morbilidad de la esquizofrenia y el trastorno en el uso de sustancias, ha aumentado debido al incremento de este diagnstico, a los efectos negativos observados en el sujeto y a los costos en los servicios de salud. Este trastorno dual puede tener efectos dramticos en el curso clnico del trastorno psictico tales como: mayores recadas, re-hospitalizaciones, sntomas ms severos, no adherencia al tratamiento antipsictico, cambios marcados del humor, aumento en el grado de hostilidad e ideacin suicida, as como alteraciones en otras reas del funcionamiento incluyendo violencia, victimizacin, indigencia y problemas legales. La literatura proveniente en particular de Estados Unidos y Europa sugiere que el rango de prevalencia para este diagnstico puede oscilar entre el 10% hasta el 70%. En este estudio, revisamos la prevalencia del diagnstico dual de esquizofrenia y trastorno en el uso sustancias, as como sus caractersticas sociodemogrficas, con base en la literatura disponible alrededor del mundo dando nfasis en la poblacion latina. A pesar de que este diagnstico es ampliamente aceptado, se conoce poco sobre su prevalencia en la poblacin latina, sobre los factores ambientales, demogrficos, clnicos y otras caractersticas de estos individuos. Un mejor conocimiento sobre este diagnstico permitira mejorar los mtodos para la deteccin y adecuada valoracin del trastorno en el uso de sustancias en personas con trastornos metales severos como la esquizofrenia.

Estereotipos Sexuales y su Relacin con Conductas Sexuales Riesgosas1,2,3

Resumen Los estereotipos sexuales son creencias generalmente aceptadas y poco cuestionadas que podran contribuir a cmo los hombres y las mujeres debemos expresar nuestra sexualidad. Los objetivos de este estudio eran identificar cuntos hombres y mujeres heterosexuales en Puerto Rico endosaban ciertos estereotipos acerca de la sexualidad masculina y femenina y explorar la relacin entre el endoso de estos estereotipos sexuales y las actitudes hacia el condn masculino y su uso en relaciones sexuales vaginales Llevamos a cabo un estudio descriptivo-correlacional mediante el cual le administramos dos escalas, una sobre sexualidad masculina y otra sobre sexualidad femenina a un grupo de 429 personas heterosexuales. Encontramos que los hombres endosaron estereotipos sexuales masculinos y femeninos ms que las mujeres y que estos tienden a tener una visin ms conservadora respecto a la sexualidad femenina que la que tienen sobre su propia sexualidad. Las mujeres, por otra parte, tienden a ver su propia sexualidad y la sexualidad masculina en trminos menos estereotipados y ms equitativos.

The South Ivorian Forest has suffered a large rainfall deficit for 25 years. At the same time, it has been noticed that the movement of the coffee and cocoa production seems concomitant with that of the isohyets during recent decades. The variations in albedo and rainfall gradient seem to be linked to the significant changes to the forest cover. These could affect precipitation locally.

Modelisation de l'interaction entre une impulsion laser ultrabreve et une nanostructure plasmonique en milieu aqueux  

NASA Astrophysics Data System (ADS)

There is still a limited understanding of the basic mechanisms and processes triggered by laser irradiation that lead to the damaging of the surrounding structures. In particular, there exists for the moment no complete modelling of the process that includes all potential sources of cellular damage, including temperature rise, plasma generation, pressure wave emission and vapor bubble formation. This thesis presents such a modelling, with the cell environment emulated by a much simpler aqueous medium. Water is used as its optical, mechanical and thermal characteristic are similar enough to the cell environment to enable the transposition of the results and tendencies observed in water to this medium. Modelling consists in a continuous medium based approach that uses coupled partial differential equations to simulate the nanostructure-water system's response to an ultrafast laser pulse. The time-dependant field distribution in the system is simulated using classical electromagnetic theory, while the temperature in the nanostructure is calculated using a two-temperature model. Generation and heating of a plasma in the nanostructure's vicinity from photoionization and impact ionization in the near-field, as well as from photothermal emission from the nanostructure at the metal interface are also included. This plasma locally modifies the refractive index, which alters the simulated optical response of the system. Energy relaxation from this plasma as well as heat conduction from the nanostructure's lattice transfer energy to the water, which dynamics and thermodynamics evolutions are simulated from hydrodynamic and energy conservation equations. Modelling is used for analyzing the interaction of a near-infrared ultrafast laser pulse (45 fs, 800 nm, 200 mJ/cm2) with two distinct systems : a 100nm gold nanoparticle and a 10x41 nm2 gold nanorod. The gold nanoparticle shows a plasmon resonance at a 550 nm wavelength, and is thus slightly off-resonance at the 800 nm irradiation wavelength. In opposition, the gold nanorod shows a plasmon resonance directly at 800 nm and is thus in-resonance at the irradiation wavelength. The system of tightly coupled time-dependant non-linear partial differential equations is solved in 3D using a finite-element method. The modelling shows the generation of vapor bubble around both systems, which maximal diameter and growth time are validated from spectroscopic measurements. Results show an important production of plasma in the nanostructure's near field, which fast relaxation heats rapidly the surrounding water, leading to the emission of strong pressure wave and to the formation of a vapor bubble. Simulations further demonstrate the crucial importance of the plasma in the cavitation mechanism. For both the nanoparticle and the nanorod, results show that most of the laser energy is indeed absorbed in the plasma surrounding the nanostructure rather than in the nanostructure itself. In particular, the energy absorbed in the nanoparticle is shown to be insufficient to induce the formation of a vapor bubble at 200 mJ/cm2, whereas such a bubble is experimentally observed. This is a major result of the thesis, as such a plasma-mediated plasmonic enhanced cavitation mechanism has never been reported in the literature. The existence of this plasma-mediated mechanism that does not rely on the particle extreme heating to initiate cavitation has important consequences on cell nanosurgery applications. Finally, based on the same modelling, we develop a simple and efficient method to evaluate the potential of specific nanostructures and irradiation parameters for cell nanosurgery. We introduce a performance factor based on minimizing the energy density deposited in the nanostructure to avoid fragmentation, while maximizing the overall energy deposited in the system, to enhance the production of vapor bubbles. Results predict off-resonance 175 nm gold nanoparticles to be best suited for near-infrared ultrafast laser cell nanosurgery using 45 fs pulses at a wavelength of 800 nm. They also confirm the low inte

Potential misuse of avian density as a conservation metric [Potencial Mal Uso de la Densidad de Aves como un Indicador de Conservaci??n  

USGS Publications Warehouse

Effective conservation metrics are needed to evaluate the success of management in a rapidly changing world. Reproductive rates and densities of breeding birds (as a surrogate for reproductive rate) have been used to indicate the quality of avian breeding habitat, but the underlying assumptions of these metrics rarely have been examined. When birds are attracted to breeding areas in part by the presence of conspecifics and when breeding in groups influences predation rates, the effectiveness of density and reproductive rate as indicators of habitat quality is reduced. It is beneficial to clearly distinguish between individual- and population-level processes when evaluating habitat quality. We use the term reproductive rate to refer to both levels and further distinguish among levels by using the terms per capita fecundity (number of female offspring per female per year, individual level) and population growth rate (the product of density and per capita fecundity, population level). We predicted how density and reproductive rate interact over time under density-independent and density-dependent scenarios, assuming the ideal free distribution model of how birds settle in breeding habitats. We predicted population density of small populations would be correlated positively with both per capita fecundity and population growth rate due to the Allee effect. For populations in the density-dependent growth phase, we predicted no relation between density and per capita fecundity (because individuals in all patches will equilibrate to the same success rate) and a positive relation between density and population growth rate. Several ecological theories collectively suggest that positive correlations between density and per capita fecundity would be difficult to detect. We constructed a decision tree to guide interpretation of positive, neutral, nonlinear, and negative relations between density and reproductive rates at individual and population levels. ?? 2010 Society for Conservation Biology.

Um interessante fenmeno lingstico presente nas interaes das pessoas bilngues a alternncia de lnguas. Neste trabalho, estamos investigando a alternncia entre a lngua portuguesa oral e a lngua de sinais brasileira Libras, numa mesma cadeia enunciativa, com o objetivo de identificar e analisar o uso dessa alternncia na fala de uma criana e de um adulto (ambos ouvintes, filhos de pais surdos), interagindo em uma situao de bilinguismo intermodal, com interlocutores surdos e ouvintes. A alternncia de lnguas, nesse caso, ocorre quando se para de falar em portugus e se alterna para sinalizar. O presente trabalho se caracteriza como um estudo inicial, com anlise qualitativa de dados. Fazem parte do nosso corpus nove sesses de interaes em Libras e em portugus oral, gravadas em vdeo, que fazem parte do Projeto Desenvolvimento Bilngue Bimodal da UFSC. Os dados revelam que as caractersticas da alternncia de lnguas pelo adulto e pela criana parecem ter semelhanas e diferenas. O sujeito adulto parece ter feito um uso da alternncia mais preocupado com o curso da interao. A criana, por sua vez, no parece t-la usado com propsitos pragmticos especficos. Quanto extenso das alternncias, pode-se perceber que tanto a criana quanto o adulto utilizaram enunciados maiores do que uma nica palavra isolada. O papel dos interlocutores parece ter sido decisivo nas interaes aqui investigadas especialmente nas do adulto, j que a criana ainda est em processo de tomada de conscincia do papel do interlocutor na interao.

Introduccin Estudios internacionales demuestran que existe un patrn diferenciado de salud y una disparidad en la atencin sanitaria entre personas con discapacidad intelectual (DI) y poblacin general. Objetivo Obtener datos sobre el estado de salud de las personas con DI y compararlos con datos de poblacin general. Pacientes y mtodos Se utiliz el conjunto de indicadores de salud P15 en una muestra de 111 sujetos con DI. Los datos de salud encontrados se compararon segn el tipo de residencia de los sujetos y se utiliz la Encuesta Nacional de Salud 2006 para comparar estos datos con los de la poblacin general. Resultados La muestra con DI present 25 veces ms casos de epilepsia y el doble de obesidad. Un 20% present dolor bucal, y existi una alta presencia de problemas sensoriales, de movilidad y psicosis. Sin embargo, encontramos una baja presencia de patologas como la diabetes, la hipertensin, la osteoartritis y la osteoporosis. Tambin presentaron una menor participacin en programas de prevencin y promocin de la salud, un mayor nmero de ingresos hospitalarios y un uso menor de los servicios de urgencia. Conclusiones El patrn de salud de las personas con DI difiere del de la poblacin general, y stas realizan un uso distinto de los servicios sanitarios. Es importante el desarrollo de programas de promocin de salud y de formacin profesional especficamente diseados para la atencin de personas con DI, as como la implementacin de encuestas de salud que incluyan datos sobre esta poblacin.

Deteccin automtica de NEOs en imgenes CCD utilizando la transformada de Hough  

NASA Astrophysics Data System (ADS)

El inters y la dedicacin por los objetos que se acercan a la rbita de la Tierra (NEOs) ha aumentado considerablemente en los ltimos aos, tanto que se han iniciado varias campaas de bsqueda sistemtica para aumentar la poblacin identificada de stos. El uso de placas fotogrficas e identificacin visual est siendo sustitudo, progresivamente, por el uso de cmaras CCD y paquetes de deteccin automtica de los objetos en las imgenes digitales. Una parte muy importante para la implementacin exitosa de un programa automatizado de deteccin de este tipo es el desarrollo de algoritmos capaces de identificar objetos de baja relacin seal-ruido y con requerimientos computacionales no elevados. En el presente trabajo proponemos la utilizacin de la transformada de Hough (utilizada en algunas reas de visin artificial) para detectar automticamente trazas, aproximadamente rectilneas y de baja relacin seal-ruido, en imgenes CCD. Desarrollamos una primera implementacin de un algoritmo basado en sta y lo probamos con una serie de imgenes reales conteniendo trazas con picos de seales de entre ~1 ? y ~3 ? por encima del nivel del ruido de fondo. El algoritmo detecta, sin inconvenientes, la mayora de los casos y en tiempos razonablemente adecuados.

Relations quantitatives entre les craies silex et les formations rsiduelles silex de l'ouest du bassin de Paris  

NASA Astrophysics Data System (ADS)

During the past century, the autochthonous and allochthonous origin of clay with flints from underlying chalk rocks has been the subject of many discussions. In order to have a better understanding of the origin of this unit, a weathering balance between chalk and clay with flints was made. This balance was estimated by an accurate knowledge of mother chalk ages and by comparison of grain size distribution and geochemistry between chalk and clay with flints. These comparisons are based on the quantities of flints in chalk and in clay with flints, because flints are autochthonous and their weathering is calculated. Results provide several new elements on the Cretaceous evolution of the Paris-London Basin: chalk of Maastrichtian age existed in the Paris Basin, and we now have good estimations of the quantities of chalk that disappeared through weathering. Results further show that the stratigraphic succession of chalk is maintained in the clay with flints. Additionally, flints (autochthonous elements of clay with flints) are only slightly weathered. Clay with flints matrix is composed of a significant allochthonous fraction in the first 10 m, which diminishes with depth and disappears below a depth of 20 m. Pure clay with flints issued from chalk decarbonatation only exists at a depth greater than 20 m.

Consquences de l'interaction entre prfrences pour l'habitat et quantit de ressources trophiques sur les communauts d'insectes coprophages (Coleoptera: Scarabaeoidea)  

NASA Astrophysics Data System (ADS)

Between the years 1988 and 1995, five dung beetle communities were studied in combined conditions of habitat and trophic resources. Investigations were conducted on La Viale experimental farm, in the Causse Mjean, southern France. At each site, dung beetle traps of standard design were set up simultaneously. In most situations, the vegetation cover acted like a filter that allowed the penetration of several ubiquitous but fundamentally open-habitat dung beetle species into forest, at the same time drastically limiting their numbers. Open and close sites differed significantly, open and grazed sites showing the highest richness, abundance and biomass in beetles. Both in open and close sites, a significant increase in trophic resources led to an increase of the diversity and evenness. However in open-habitat, when resources were too abundant, few species were favoured and the diversity and evenness decreased. In forest-habitat, a continuous grazing during several years (increase in resources) modified the dung beetle community, with a high increase in the numbers and biomass of beetles but a smaller increase in richness. Numbers in forest habitat readjusted to the level observed in open habitat with equivalent trophic resources. Similarly to what was observed in open pastures, the forest communities were able to adjust their numbers to the level of available trophic resources. Resources were a more active variable than the structure of habitat on the dung beetle communities. Important resources go against the filter effect which allows the penetration under cover of open-habitat species. Changes were slow (several years), and forest communities remained weak. The poverty of forest habitats is discussed: This scarcity in species is probably due to long time human activities in Europe which drastically reduced forest habitats and developped grazing, favouring generalist and heliophilous open-habitat dung beetle species. Actual grassland communities in Europe are richer than their homologous communities in North America. Conversely, in North America where human activities are recent, the true forest dung beetle communities are still diverse and richer than grassland communities.

Transect sismique continu entre l'arc des Nouvelles-Hbrides et la marge orientale de l'Australie: programme FAUST (French Australian Seismic Transect)  

NASA Astrophysics Data System (ADS)

Within the framework of the joint FAUST (French Australian Seismic: Transect) program, the Australian research vessel Rig-Seismic recorded a series of multichannel seismic profiles between the New Hebrides Arc and the Australian Margin. The very high quality of these profiles allows the examination of the continental or oceanic basement over the whole area surveyed. In basins beneath the eastern margin of the northern Lord Howe Rise and the New Caledonia Basin, where the crust is thinner, the Moho discontinuity is present at about 8.5 seconds two-way time (TWT) (about 12-13 km) on the profiles processed onboard. The data collected suggest that the sedimentary section within the basins includes syn-rift Cretaceous sediments that are not yet definitively identified. The Upper Eocene-Middle Oligocene subduction of the Australian plate beneath the Pacific plate is highlighted by thrust faults concentrated along the Lord Howe, Norfolk and Fairway Ridges. This episode probably corresponds to the period of convergent tectonism associated with the Upper Eocene obduction of the New Caledonian ophiolites.

Relations structurales entre U 3O 8 et quelques fluorures mixtes de formules M2M' 3F 11, MM' 2F 7 et MM' 3F 10  

NASA Astrophysics Data System (ADS)

U 3O 8 oxide, as well as M2M' 3F 11, MM' 2F 7 and MM' 3F 10 fluorides, with M = Rb, Tl, Cs, NH 4 and M' = In, Lu, Yb, Tm, is described as the regular repetition according to the A-A-A sequence of identical and parallel sheets of edge-and corner-sharing M'F 7 or UO 7 pentagonal bipyramids and M'F 6 octahedra. M' and U atoms are systematically located at the lattice points of a pseudohexagonal network, but in the fluorides some of these lattice points are vacant, producing hexagonal tunnels in which M atoms are located. It is shown that in the two kinds of compounds the same linear chains and M' 3X17 groups of pentagonal bipyramids are present, and that the transformation of the U 3O 8 structure into the fluorides can be achieved by an ordered substitution of some linear U?O?U?O chains by M- M- M chains. All these structures can be described with the same structural model based on the chemical twinning principle.

En este estudio se busc la asociacin entre el uso de duchas vaginales y otros factores de riesgos con VB. Se us un diseo observacional descriptivo transversal prospectivo, en 1,252 mujeres que asistieron al servicio de planificacin familiar de tres hospitales nacionales (Dos de Mayo, Arzobispo Loayza, San Bartolom) y el Instituto Materno Perinatal, durante el ao 1997. Se utiliz un cuestionario estructurado donde se registraron variables socio demogrficas y caractersticas del estilo de vida de las participantes. VB fue diagnosticada mediante el puntaje de Nugent. Se emple anlisis de regresin logstica para calcular odds ratio (OR) e intervalos de confianza al 95%. La edad promedio de las participantes fue 25.1 4,7 aos, el 23.4% tenan ms de 11 aos de educacin. La prevalenca de VB fue 20,1%. Las mujeres que practicaban duchas vaginales tuvieron 2.28 veces (OR = 2.28, IC 95% [1.05.0]) mayor probabilidad de tener VB comparado con aquellas que no lo practicaban. Tener dos o ms parejas sexuales estuvo asociado con 2.0 veces (OR =2.0, IC 95% [1.23.5]) mayor probabilidad de adquirir VB comparado con aquellas que haban tenido solo una pareja sexual. Las participantes que iniciaron una relacin sexual a una edad temprana tuvieron 1.4 veces (OR=1.4, IC 95% [1.0 1.9]) mayor probabilidad de adquirir VB. El uso de duchas vaginales es un factor de riesgo de VB. Los programas destinados a la salud de la mujer deben abordar las repercusiones perjudiciales para la salud asociados con las duchas vaginales. PMID:21132048

El Internet como fuente de informacin sobre la salud: la visin de estudiantes de Andaluca, Espaa.

El Internet (la red para usuarios de computadora) puede ser una herramienta til para adolescentes y jvenes en la bsqueda y uso de informacin sobre la salud. Las razones para ello han sido descritas en diversos estudios, sin embargo la confianza en la informacin disponible en el Internet es variable y persisten necesidades de alfabetizacin para su uso. Tanto el sistema de salud como el educativo pueden desempear un papel fundamental para el asesoramiento de la materia. Es necesario conocer las opiniones que tienen los estudiantes de educacin secundaria y de universidad en Andaluca, Espaa, sobre la relacin entre el Internet y la salud, el concepto de salud y la imagen que proyecta el Internet y el 'social media' (medios o redes sociales electrnicos) con relacin a la juventud y su salud. Hemos desarrollado un estudio, usando tcnicas de etnografa virtual: hemos consultado a 55 estudiantes de enseanza secundaria en foros virtuales y a 21 estudiantes universitarios en video entrevistas semi-estructuradas. Los estudiantes aportaron un concepto de salud integral, relacionado con los hbitos de salud fsica y emocional, y con los activos o factores positivos para la salud. Exponen una visin crtica de la utilidad del Internet para la salud, y sobre la calidad y credibilidad de los contenidos de salud en el Internet, manifestando la necesidad de tener asesoramiento y alfabetizacin. Presentan una opinin alternativa, ms positiva que la visin que se da en social media e Internet sobre sus estilos de vida, y sugieren desarrollar al Internet como herramienta para potenciar la conversacin participativa y el aprendizaje en salud.

Le complexe annulaire d'ge Oligocne de l'Achkal (hoggar Central, Sud Algrie) : tmoin de la transition au Cnozoque entre les magmatismes tholitique et alcalin. vidences par les isotopes du Sr, Nd et Pb  

NASA Astrophysics Data System (ADS)

The Achkal Oligocene ring complex cross-cuts the Upper Eocene tholeiitic traps located on the top of the Hoggar swell. The plutonic rocks range from tholeiitic gabbros to alkali essexites, monzonites and syenites, whereas the volcanites are restricted to late peralkaline rhyolites. The affinity change linked to the large isotopic heterogeneities (from EM1 to HIMU) suggests that the parental magmas are issued from two distinct mantle sources, first lithospheric then deeper. The Achkal has recorded the magmatic evolution of the Hoggar hot spot, between Eocene and Miocene.

La lithostratigraphie des grandes zones structurales des Mauritanides, entre le 14e et le 16e parallles nord (Sngal oriental et Rp. Isl. de Mauritanie). Essai d'interpretation geodynamique  

NASA Astrophysics Data System (ADS)

In eastern Senegal and southern Mauritania, the thrusted and more or less metamorphosed units of the Mauritanides belt involve similar lithostratigraphical sequences including, from the bottom to the top, a green volcano-sedimentary series (Nagara and Bouly groups) then a detrital red series (Ndoumli group) and a quartzitic series (Ndio group). In the more external part of the belt these sequences are completed with coarse sandstones which are thought to be the equivalent of upper Ordovician sediments of glacial origin (Sakha group) and, at the top, red fossiliferous sandstones of Devonian age. All of these sequences can be correlated with the upper Proterozoic-Devonian sedimentary sequence of the West African craton. The facies variations as well as the volcanic features allow one to define four main structural zones that are, from east to west: an Autochthonous, which includes the western margin of the Taoudeni basin, a Parautochthonous, displaced but not metamorphosed, an External Zone which comprises basic and ultrabasic rocks, and an Internal Zone marked by acid and andesitic metavolcanism. These zones are more or less linked with palaeogeographic domains which were created during an upper Precambrian distensive phase occurring prior to the Mauritanides orogeny. The detrital sedimentation is regarded as the result of the erosion of structures which arose during different stages of a compressive taconic-hercynian event.

Healing war wounds and perfuming exile: the use of vegetal, animal, and mineral products for perfumes, cosmetics, and skin healing among Sahrawi refugees of Western Sahara  

PubMed Central

Background Over the past decade, there has been growing interest within ethnobiology in the knowledge and practices of migrating people. Within this, scholars have given relatively less attention to displaced people and refugees: to the loss, maintenance, and adaptation of refugees ethnobiological knowledge, and to its significance for refugees wellbeing. This study focuses on cosmetics and remedies used to heal skin afflictions that are traditionally used by Sahrawi refugees displaced in South Western Algerian refugee camps. Methods The research methods included a structured survey carried out with 37 refugee households, semi-structured interviews with 77 refugees, 24 retrospective interviews with refugees and other knowledgeable informants, and a voucher specimen collection of the plants and products cited. Results We recorded the use of 55 plant species, nine animal species, and six mineral products used within the three main use categories discussed in this paper: 1) Remedies for health issues that are typical of the desert environment where the Sahrawi once lived as nomads and now live as refugees (e.g. eye afflictions); 2) Remedies for wounds that are influenced by the Sahrawis recent history of guerrilla warfare; and 3) Cosmetics and products used for body care, decoration and perfuming (e.g. hair care, teeth cleansing, henna use) and for aromatizing the air inside of tents and which are widely used in everyday life and social practices. Conclusions We discuss the changes that have occurred in the patterns of use and procurement of these products with exile and sedentarization in refugee camps, and conclude that refugees are not simply passive recipients of national and international aid, but rather struggle to maintain and recover their traditional ethnobiological practices in exile. Finally, we suggest further research into the ethnobiological practices and knowledge of displaced populations. Resumen Sanando las heridas de guerra y perfumando el exilio: el uso de productos vegetales, animales y minerales con fines de perfumera, cosmtica y curativos de la piel entre los refugiados saharauis del Shara Occidental. Antecedentes Durante la ltima dcada ha habido un creciente inters en los estudios etnobiolgicos de los conocimientos y prcticas de las personas que migran. Dentro de esta tendencia, los estudiosos han prestado relativamente menor atencin a las personas desplazadas y a los refugiados: a la prdida, el mantenimiento y la adaptacin de sus conocimientos etnobiolgicos, y su importancia para el bienestar de los refugiados. Este estudio se centra en los cosmticos y remedios para curar problemas de la piel tradicionalmente utilizados por los refugiados saharauis en los campamentos de desplazados al sudoeste de Argelia. Mtodos Los mtodos de investigacin que se utilizaron son: una encuesta estructurada con 37 familias de refugiados, entrevistas semi-estructuradas con 77 refugiados, 24 entrevistas retrospectivas con refugiados e informantes conocedores, y una coleccin de muestra de las plantas y productos citados. Resultados Se registr el uso de 55 especies vegetales, nueve especies animales, y seis productos minerales utilizados en tres principales categoras de usos: 1) Recursos contra los problemas de salud caractersticos del entorno desrtico donde una vez vivieron los saharauis como nmadas y donde ahora viven como refugiados (por ejemplo problemas en los ojos); 2) Remedios para heridas que reflejan la historia reciente de guerra de guerrilla de los nmadas saharauis; y 3) Cosmticos y productos utilizados para el cuidado del cuerpo, decoracin y perfumes (por ejemplo, atencin al cabello, limpieza de dientes, uso del henna) y como aromatizantes del aire al interior de las tiendas, que son ampliamente utilizados en la vida y las prcticas sociales cotidianas de los refugiados.

Urbanization and the groundwater budget, metropolitan Seoul area, Korea  

NASA Astrophysics Data System (ADS)

The city of Seoul is home to more than 10 million people in an area of 605 km2. Groundwater is ed for public water supply and industrial use, and to drain underground facilities and construction sites. Though most tap water is supplied from the Han River, the quantity and quality of groundwater is of great concern to Seoul's citizens, because the use of groundwater for drinking water is continuously increasing. This study identifies the major factors affecting the urban water budget and quality of groundwater in the Seoul area and estimates the urban water budget. These factors include leakage from the municipal water-supply system and sewer systems, precipitation infiltration, water-level fluctuations of the Han River, the subway pumping system, and domestic pumping. The balance between groundwater recharge and discharge is near equilibrium. However, the quality of groundwater and ability to control contaminant fluxes are impeded by sewage infiltration, abandoned landfills, waste dumps, and abandoned wells. Rsum. La ville de Soul possde une population de plus de 10 millions d'habitants, pour une superficie de 605 km2. Les eaux souterraines sont pompes pour l'eau potable et pour les usages industriels, ainsi que pour drainer les quipements souterrains et les sites en construction. Bien que l'essentiel de l'eau potable provienne de la rivire Han, la quantit et la qualit de l'eau souterraine prsentent un grand intrt pour les habitants de Soul, parce qu'on utilise de plus en plus l'eau souterraine pour l'eau potable. Cette tude identifie les facteurs principaux qui affectent la qualit de l'eau souterraine dans la rgion de Soul et fait l'estimation du bilan d'eau urbaine. Les principaux facteurs affectant le bilan d'eau urbaine et la qualit de l'eau souterraine sont les fuites du rseau d'adduction et du rseau d'gouts, l'infiltration des eaux de prcipitation, les fluctuations du niveau de la rivire Han, le rseau de pompage du mtro et les pompages privs. Le bilan entre la recharge de la nappe et sa dcharge est proche de l'quilibre. Cependant, les infiltrations d'eaux uses, les dcharges abandonnes, les dcharges d'ordures et les puits abandonns portent atteinte la qualit de l'eau souterraine et la capacit de contrler les flux de contaminants. Resumen. La ciudad de Sel tiene ms de 10 millones de habitantes en un rea de 605 km2. Se bombea aguas subterrneas para abastecimiento urbano y para usos industriales, as como para el drenaje de instalaciones subterrneas y de solares en construccin. Aunque la mayor parte del agua de boca procede del ro Han, los ciudadanos de Sel estn muy concienciados por la cantidad y calidad de las aguas subterrneas, ya que su explotacin para uso de boca est experimentando un continuo incremento. El presente estudio identifica los factores que ms afectan a la calidad de las aguas subterrneas en el rea de Sel y hace una estimacin del balance de agua en el territorio urbano. Entre los factores principales que afectan al balance y a la calidad de las aguas subterrneas, se incluye el lixiviado de la red municipal de suministro y de la red de alcantarillado, la infiltracin de agua de lluvia, las fluctuaciones del nivel del ro Han, el sistema de bombeo del metro y los bombeos domsticos. El balance entre la recarga y la descarga en el acufero est prximo al equilibrio. Sin embargo, la calidad de las aguas subterrneas y la capacidad de controlar los flujos de contaminacin estn amenazadas por la infiltracin de aguas residuales, vertederos abandonados, depsitos de residuos y pozos abanadonados.

Prediction uncertainty of plume characteristics derived from a small number of measuring points  

NASA Astrophysics Data System (ADS)

A small number of measuring points may inflict a bias on the characterisation of flow and transport based on field experiments in the unsaturated zone. Simulation of pure advective transport of a Gaussian plume through a setup of 30 regularly placed measuring points revealed regular temporal fluctuations about the real spatial moments. An irregular setup predicted both irregular fluctuations and larger discrepancies from the real value. From these considerations, a regular setup is recommended. Spatial moments were sensitive to the plume size relative to the distance between individual measuring points. To reduce prediction errors of the variance, the distance between the measuring points should be less than twice the standard deviation of the examined plume. The total size of the setup should cover several standard deviations of the plume to avoid mass being lost from the monitored area. Numerical simulations of a dispersing plume (comparing calculations based on 9000 nodes with 30 measuring points) revealed that vertical and horizontal centres of mass were predicted well at all degrees of heterogeneity, and the same was the case for horizontal variances. Vertical variances were more susceptible to prediction errors, but estimates were of the same order of magnitude as the real values. Rsum Lorsque l'on cherche caractriser l'coulement et le transport partir d'expriences de terrain dans la zone sature, il arrive qu'un petit nombre de points introduisent un biais. La simulation d'un transport purement advectif d'un panache gaussien au travers d'un ensemble de 30 points de mesures espacs rgulirement fait apparatre des variations temporelles rgulires autour des moments spatiaux rels. Un ensemble irrgulier conduit prdire la fois des variations irrgulires et de plus grandes divergences par rapport la valeur relle. A partir de ces constations, un ensemble rgulier est recommand. Les moments spatiaux sont apparus sensibles la dimension du panache en fonction de la distance entre les diffrents points de mesure. Afin de rduire les erreurs de prdiction de la variance, la distance entre les points de mesure doit tre infrieure au double de l'cart-type du panache examin. La dimension totale de l'ensemble doit couvrir une tendue de plusieurs carts-types du panache pour viter qu'une partie de la matire chappe la zone surveille. Des simulations numriques du panache en dispersion (les calculs de comparaison sont bass sur 9000 nuds avec 30 points de mesure) montrent que le centre vertical et le centre horizontal de la matire disperse ont t bien prdits tous les degrs d'htrognit, de mme que pour les variances horizontales. Les variances verticales ont t plus sensibles aux erreurs de prdiction, mais les estimations taient du mme ordre de grandeur que les valeurs relles. Resumen Un nmero pequeo de puntos de medida puede producir un sesgo en la caracterizacin en campo del flujo y transporte de solutos en la zona no saturada. La simulacin de transporte advectivo (no difusivo) de un penacho Gaussiano a travs de un conjunto de 30 puntos de medida regularmente distribuidos revelan fluctuaciones temporales regulares de los momentos espaciales del penacho. Una distribucin irregular de puntos de medida predijo a su vez fluctuaciones irregulares, ms alejadas de la realidad, por lo que se recomienda el uso de esquemas de muestreo regulares. Los momentos espaciales fueron sensibles a la relacin entre tamao del penacho y distancia entre puntos de medida. Para reducir los errores en la prediccin de la varianza, la distancia entre puntos de observacin debe ser menor que dos veces la desviacin estndar del penacho. El tamao del rea muestreada debe cubrir varias desviaciones estndar del penacho para evitar perder parte de la masa.

Use of digital multispectral videography to assess seagrass distribution in San Quinti??n Bay, Baja California, Mexico [Uso de videografi??a multiespectral digital para evaluar la distributio??n del pasto marino en Bahi??a San Quinti??n, Baja California, Me??xico  

USGS Publications Warehouse

Apparent threats to the spatial distribution of seagrass in San Quinti??n Bay prompted us to make a detailed assessment of habitats in the bay. Six coastal habitats and three seagrass subclasses were delineated using airborne digital multispectral videography (DMSV), Eelgrass, Zostera marina, was the predominant seagrass and covered 40% (1949 ha) of the areal extent of the bay in 1999. Eelgrass grew over a wide range of tidal depths from about -3.0 in mean lower low water (MLLW) to about 1.0 m MLLW, but greatest spatial extent occurred in intertidal areas -0.6 m to 1.0 m MLLW. Exposed-continuous (i.e., high density) eelgrass was the most abundant habitat in the bay. Widgeongrass, Ruppia maritima, was the only other seagrass present and covered 3% (136 ha) of the areal extent of the entire bay. Widgeongrass grew in single species stands in the upper intertidal (??? 0.4 MLLW) and intermixed with eelgrass at lower tidal depths. Overall accuracy of the six habitat classes and three subclasses in the DMSV map was relatively high at 84%. Our detailed map of San Quintin Bay can be used in future change detection analyses to monitor the health of seagrasses in the bay.

CO2-rich thermomineral groundwater in the Betic Cordilleras, southeastern Spain: Genesis and tectonic implications  

NASA Astrophysics Data System (ADS)

The CO2-rich thermal groundwater in the Betic Cordilleras in Spain has been studied with regard to the geological and hydrogeological setting, physical and chemical characteristics, and 13C-isotope content. The study area is about 60km northeast of Almera city, in southeastern Spain. The thermomineral waters are plentiful and are related to regional geothermal anomalies. Temperatures of 20 -41C, high bicarbonate concentrations (183-1824mg/L), and high amounts of PCO2 (<1.1bar) characterize the groundwater. CO2 spatial variations are related to proximity to the Carboneras, Palomares, and Guadalentn fault systems, which may be the surface representation of the zone of crustal thinning and magmatism. ?13C values probably indicate a deep source for the CO2, either the mantle or perhaps carbonate rocks in the metamorphic substratum. The high amount of CO2 in the groundwater causes problems in wells and severely restricts water usage. The hydrothermal features of this area are probably related to neotectonic activity. Rsum Les eaux thermales teneurs leves en CO2 des Cordillres Btiques ont ttudies, spcialement en ce qui concerne les aspects gologiques et hydrogologiques, leurs caractristiques physiques et chimiques, et leurs teneurs en 13C. La zone d'tude est situe 60km environ au nord-est de la ville d'Almera, au sud-est de l'Espagne. Les eaux thermominrales sont nombreuses et sont en relation avec les anomalies gothermales rgionales. L'eau souterraine a une temprature comprise entre 20-41C, une concentration leve en bicarbonates (entre 183 et 1824mg/L), et PCO2leve (<1.1bars). Les variations spaciales de CO2 sont en rapport avec la proximit des systmes de failles de Carboneras, Palomares et Guadalentin, et peuvent tre la manifestation en surface d'une zone d'amincissement cortical. Les donnes de ?13C indiquent un apport probable d'origine profonde de CO2, ventuellement du manteau et/ou des roches carbonates prsentes dans le substratum mtamorphique. Les concentrations leves en CO2 dans l'eau souterraine posent des problmes dans les forages et dans l'utilisation de l'eau. Le caractre hydrothermal de cette rgion serait en rapport avec son activit notectonique. Resumen Las aguas termales con elevados contenidos en CO2 de las Cordilleras Bticas han sido estudiadas en relacin con los aspectos geolgicos e hidrogeolgicos, sus caractersticas fsicas y qumicas, y sus contenidos en 13C. El rea de estudio se encuentra aproximadamente a 60km al noreste de la ciudad de Almera, en el sureste de Espaa. Las aguas termominerales son numerosas y estn relacionadas con anomalas geotermales regionales. El agua subterrnea tiene una temperatura comprendida entre 20-41C, alta concentracin de bicarbonatos (entre 183-1824mg/L) y elevada PCO2 (<1.1bares). Las variaciones espaciales de CO2 estn relacionadas con la proximidad de los sistemas de fallas de Carboneras, Palomares y Guadalentn, y puede ser la manifestacin en superficie de una zona de adelgazamiento cortical. Los datos de ?13C indican un posible aporte de origen profundo de CO2, posiblemente del manto y/o de las rocas carbonatadas presentes en el sustrato metamrfico. Las elevadas concentraciones de CO2 en el agua subterrnea origina problemas en los sondeos y en el uso del agua. El carcter hidrotermal de este rea estara relacionado con su actividad neotectnica.

Distribution of stable isotopes in arid storms . II. A double-component model of kinematic wave flow and transport  

NASA Astrophysics Data System (ADS)

A new mathematical method based on a double-component model of kinematic wave flow and approach assesses the dynamic isotopic distribution in arid rain storms and runoff. This model describes the transport and ?18O evolution of rainfall to overland flow and runoff in an arid rocky watershed with uniformly distributed shallow depression storage. The problem was solved numerically. The model was calibrated using a set of temporal discharge and ?18O distribution data for rainfall and runoff collected on a small rocky watershed at the Sede Boker Experimental Site, Israel. Simulation of a reliable result with respect to observation was obtained after parameter adjustment by trial and error. Sensitivity analysis and model application were performed. The model is sensitive to changes in parameters characterizing the depression storage zones. The model reflects the effect of the isotopic memory in the water within the depression storage between sequential rain spells. The use of the double-component model of kinematic wave flow and transport provides an appropriate qualitative and quantitative fitting between computed and observed ?18O distribution in runoff. RsumUne nouvelle mthode mathmatique base sur un modle double composante d'coulement et de transport par une onde cinmatique a t dveloppe pour valuer la distribution dynamique en isotopes dans les prcipitations et dans l'coulement en rgion aride. Ce modle dcrit le transport et les variations des ?18O de la pluie vers le ruissellement et l'coulement de surface dans un bassin aride rocheux o le stockage se fait dans des dpressions peu profondes uniformment rparties. Le problme a t rsolu numriquement. Le modle a t calibr au moyen d'une chronique de dbits et d'une distribution des ?18O dans la pluie et dans l'coulement de surface sur un petit bassin versant rocheux du site exprimental de Sede Boker (Isral). La simulation d'un rsultat crdible par rapport aux observations a t obtenu aprs un ajustement des paramtres par une mthode d'essais et d'erreurs. L'analyse de sensibilit et l'application du modle ont ensuite t raliss. Le modle est plutt sensible aux changements des paramtres caractrisant les zones de stockage dans les dpressions. Le modle rend compte de l'effet de mmoire isotopique dans l'eau dans le stockage des dpressions entre les vnements squentiels de pluie. L'utilisation d'un modle double composante d'coulement et de transport par onde cinmatique permet un ajustement qualitatif et quantitatif adapt entre les distributions des ?18O calcules et observes dans l'coulement de surface. Resumen Un nuevo mtodo matemtico basado en un modelo de doble componente de onda cinemtica de flujo y transporte permite caracterizar la distribucin isotpica dinmica de las tormentas en zonas ridas y la escorrenta. Este modelo describe el transporte y la evolucin del ?18O en la lluvia, flujo superficial y escorrenta en una cuenca rocosa de clima rido con detencin superficial distribuida uniformemente. El modelo se calibr numricamente utilizando un conjunto de datos de descarga temporal y de distribucin de ?18O para lluvia y escorrenta recogida en una pequea cuenca rocosa en el Centro de Experimentacin de Sede Boker, Israel. Se obtuvo un buen ajuste a los datos tras un ajuste de parmetros mediante prueba y error. Se realiz un anlisis de sensibilidad que indic que el modelo resulta ser bastante sensible a cambios en los parmetros que caracterizan las zonas de baja detencin superficial. El modelo tambin refleja el efecto de la memoria isotpica en el agua de estas zonas de detencin entre los distintos periodos de lluvias. El uso de un modelo de doble componente de onda cinemtica de flujo y transporte proporciona un buen ajuste cualitativo y cuantitativo entre los datos medidos y calculados de ?18O en la escorrenta.

Comunicacin de pareja y VIH en mujeres en desventaja social  

PubMed Central

Introduccin La epidemia de VIH y SIDA se ha diseminado rpidamente a nivel mundial tendiendo a la feminizacin, pauperizacin y heterosexualizacin. La comunicacin de pareja en torno el VIH es descrita como uno de los factores protectores en la adquisicin de esta enfermedad, favoreciendo la adopcin de conductas sexuales seguras tales como la negociacin de pareja y la utilizacin de preservativo, considerndose como un pilar fundamental en la incorporacin de medidas de autocuidado en la sexualidad femenina. Objetivo Determinar el nivel de comunicacin de pareja en torno al VIH en mujeres chilenas en desventaja social. Metodologa Cuatrocientas noventa y seis mujeres contestaron la entrevista inicial de la investigacin Testing an HIV/AIDS Prevention Intervention for Chilean Women (RO1 TW 006977 PI Cianelli). Se utiliz la escala Health protective sexual communication scale (HPC) (010 puntos). Se realiz un anlisis descriptivo utilizando el programa SPSS 16.0. Resultados El promedio del nivel de comunicacin de pareja fue de 3,26 2,7 puntos con la pareja principal, de 2,52 2,48 puntos con una segunda pareja y de 0 puntos con una tercera pareja. Los temas de menor comunicacin entre las parejas fueron el uso de preservativo y la realizacin del test para VIH antes de tener relaciones sexuales. Conclusin Las mujeres de la muestra presentan bajos niveles de comunicacin de pareja en relacin a VIH con todas sus parejas sexuales. Son necesarias estrategias que potencien este tpico dentro de las intervenciones de prevencin de VIH y SIDA de manera de fortalecer la adopcin de conductas de autocuidado en torno al tema.

Revision curricular a partir de un analisis comparativo de las discrepancias en los curriculos de una escuela de optometria en Puerto Rico con las competencias requeridas para las agencias de revalida y acreditacion 2004  

NASA Astrophysics Data System (ADS)

El proposito de esta investigacion, un estudio cualitativo de caso, fue comparar y contrastar el curriculo vigente de la Escuela de Optometria de la UIAPR con las competencias y estandares requeridos por las agencias de acreditacion y de revalida. Con este proposito, decidimos realizar una revision y un analisis de documentos: el prontuario de cada uno de los cursos de los curriculos implantados en el 1993 y en el 2001; las competencias y estandares establecidos por las agencias de revalida y de acreditacion; y las estadisticas en las que se analiza el porcentaje de estudiantes que aprueban cada una de las partes de los examenes de revalida entre el 1998 al 2003. Se realizaron entrevistas dirigidas para dar apoyo y complementar la revision y el analisis de estos documentos. Los participantes de las entrevistas fueron tres estudiantes de la clase de optometria del 2004 (ultima clase del curriculo del 1993); tres estudiantes de la clase de optometria del 2005 (primera clase graduanda del curriculo vigente) y tres profesores y/o directores de los Departamentos de Ciencias Basicas, Ciencias Clinicas y Cuidado al Paciente. Esta investigacion se enmarco en el modelo de evaluacion curricular de discrepancia de Malcolm Provus y en el modelo de desarrollo basado en competencias. Uno de los hallazgos mas importantes del estudio es que los cambios que se implantaron al curriculo del 2001 no han logrado que los estudiantes mejoren su ejecucion en los examenes de revalida. Por otro lado, se encontro que el curriculo vigente atiende completamente los estandares de la practica de Optometria, pero no las competencias. Esta informacion fue validada mediante el uso de una tabla de cotejo para el analisis de los cursos y de la informacion obtenida de las entrevistas. El estudio determina y concluye que existen discrepancias entre los prontuarios de los cursos del curriculo y las competencias requeridas por la agencia de revalida. Segundo, que el Departamento de Ciencias Basicas es el que presenta mas deficiencias en el desarrollo de las competencias. El investigador recomienda disenar e implantar un curriculo basado en competencias y proveer formacion en didactica y procesos de aprendizaje a los profesores.

Fotometria diferencial de estrelas T Tauri  

NASA Astrophysics Data System (ADS)

Neste trabalho apresentamos os resultados preliminares de um monitoramento de estrelas jovens, que pretende ser de longa durao. As estrelas esto em sua maioria localizadas no complexo Lupus-Scorpius. Nosso objetivo principal o estudo da variabilidade em escalas de tempo de minutos at vrios dias para estrelas cujos perodos no esto determinados ou apresentam discrepncias entre diferentes publicaes. A tcnica utilizada foi a fotometria diferencial, com exposies de 60s e 90s, com as cmaras CCD SBIG ST7E e ST8E acopladas aos telescpios Schmidt-Cassegrain LX200 (10 e 12 polegadas), instalados na Fundao Planetrio da Cidade do Rio de Janeiro. Os primeiros resultados indicam que a tcnica bastante slida com relao instabilidade na transparncia do cu, mesmo com o uso de telescpios de pequeno porte. Objetos de magnitude 14, no telescpio de 10 polegadas, apresentam disperses na diferena de magnitudes das comparaes, em torno de 0,008mag nas exposies de 60s. Note-se, ainda, que a disperso pode ser melhorada utilizando-se a tcnica de soma de imagens. Destacamos AK Sco, GW Lup, GQ Lup e TW Hya. AK Sco uma binria que, apesar de ter a sua rbita e perodo cobertos espectroscopicamente (13,6dias), nunca teve seus eclipses estudados por meio de fotometria. GW Lup no tem perodo determinado na literatura. Temos acompanhado este objeto h alguns anos, e sugestes de perodos entre 5 e 6 dias tm sido encontradas. O objeto que mereceu maior ateno foi TW Hya por apresentar vrios trabalhos fotomtricos e espectroscpicos com resultados discrepantes quanto ao perodo rotacional, que varia de 1,8 a 4,4 dias (Rucinsky & Krautter 1983, A&A 121, 217; Herbst & Koret 1988, AJ 96, 1949; Mekkaden 1988, A&A 340, 135; Batalha et al. 2002, ApJ 580, 343). Dedicamos 13 noites para essa estrela, totalizando cerca de 2.000 pontos na curva de luz. Nossos dados indicam a presena de uma modulao com dois perodos possveis: 2,2 ou 3,8 dias, alm de variaes irregulares superpostas. Foram observados, tambm, dois eventos sbitos, espaados de uma hora, com amplitudes de 0,05mag e durao de aproximadamente 30 minutos. Admitindo-se que tal modulao seja originada por acrscimo sobre a superfcie estelar, dois cenrios so possveis. No caso do menor perodo, apenas uma mancha quente seria visvel. No outro caso, duas manchas seriam necessrias, explicando assim a presena de dois picos ao se colocar os pontos em fase.

A protocol for storage and long-distance shipment of Mediterranean fruit fly (Diptera: Tephritidae) eggs. 1. Effect of temperature, embryo age , and storage time on survival and quality  

SciTech Connect

The operational use of Mediterranean fruit fly (medfly) Ceratitis capitata (Wiedemann), genetic sexing strains in Sterile Insect Technique applications can be maximized by developing methods for effective shipment of eggs. This would enable a central production facility to maintain the relevant mother stocks and large colonies to supply eggs to satellite centers that would mass produce only males for irradiation and release. In order to achieve this, the survival of medfly embryos of different ages was assessed after storage at 5, 10, 15, 20, and 25 deg. C in water for different periods of time. Survival was affected by all 3 variables, i.e., embryo age, water temperature, and length of storage. Storage of embryos at any temperature for 120 h resulted in almost no survival. Controlling the age of the embryo at the time of the temperature treatment is crucial for the success of this procedure. Embryos collected between 0 to 12 h after oviposition and pre-incubated at 25 deg. C for 12 h provide a suitable 72 h window for shipment when maintained between 10 to 15 deg. C. Under these conditions, no significant reductions in survival during all the developmental stages were observed. (author) [Spanish] El uso operacional de cepas de la mosca del mediterraneo Ceratitis capitata (Wiedemann) en las cuales es posible separar los sexos a traves de mecanismos geneticos para su utilizacion en la Tecnica del Insecto Esteril (TIE), puede ser maximizado con el desarrollo de metodos efectivos para el envio y transporte de huevos. Esto permite que un laboratorio de produccion centralizada mantenga las respectivas colonias responsables por la produccion de huevos para este abastecer laboratorios satelites responsables por la produccion masiva de solamente machos para subsiguiente irradiacion y liberacion. Para ser posible esta alternativa fue evaluada la supervivencia de embriones de diferentes edades despues de su almacenamiento en agua a 5, 10, 15, 20 y 25 deg. C por diferentes periodos de tiempo. La supervivencia fue afectada por las 3 variables evaluadas, la edad del embrion, la temperatura del agua y el periodo de almacenamiento. El almacenamiento de los embriones a cualquier temperatura por 120 horas dio como resultado la casi no supervivencia. Una edad controlada de los embriones a tratar es crucial para el exito de este protocolo. Embriones colectados entre 0 a 12 horas despues de la oviposicion y su previa incubacion a 25 deg. C por 12 horas brinda un margen de hasta de 72 horas de duracion del almacenamiento y transporte, siempre y cuando estos se mantengan en una temperatura de entre 10 a 15{sup o}C. En estas condiciones, fue registrada una reduccion no significante de la supervivencia de los diferentes estados de desarrollo. (author)

In this study, we developed geographically broad habitat relationship models to provide conservation prescriptions for three species that breed in farmed grasslands: Bobolink ( Dolichonyx oryzivorus), Savannah Sparrow (Passerculus

th century Latin American novels have actively taken part in the construction of national projects. In Ecuador, intellectuals from the late 19th and early 20th centuries created ideal models of the nation in which the writers reimagine the role of the Ecuadorian woman. This brief analysis of six novels published between 1863 and 1904 demonstrates the obsession of the national

Contamination par le nickel et d'autres mtaux lors de la manipulation des pices de monnaie comparaison entre francs franais et eurosContamination by nickel and other metals resulting from the manipulation of coins comparison between French francs and euros  

NASA Astrophysics Data System (ADS)

The introduction of the euro has revived the interest for potential nickel allergies. We show that the handling of a single used nickel coin releases an average of 0.45 ?g of nickel, 0.26 ?g of copper and 0.08 ?g of zinc, whereas a euro coin composed of nickel alloys releases 0.25 ?g of nickel, 1.3 ?g of copper and 0.17 ?g of zinc. These levels of contamination, favored by friction during handling, differ from those obtained on the basis of the EN 1811 test applicable to solubilisation in artificial sweat. The evaluation of allergy risks following the introduction of the euro may require the consideration of potential synergies between the metals mentioned above. To cite this article: P.-G.

Accounting for the Impact of Conservation on Human Well-Being  

PubMed Central

Conservationists are increasingly engaging with the concept of human well-being to improve the design and evaluation of their interventions. Since the convening of the influential Sarkozy Commission in 2009, development researchers have been refining conceptualizations and frameworks to understand and measure human well-being and are starting to converge on a common understanding of how best to do this. In conservation, the term human well-being is in widespread use, but there is a need for guidance on operationalizing it to measure the impacts of conservation interventions on people. We present a framework for understanding human well-being, which could be particularly useful in conservation. The framework includes 3 conditions; meeting needs, pursuing goals, and experiencing a satisfactory quality of life. We outline some of the complexities involved in evaluating the well-being effects of conservation interventions, with the understanding that well-being varies between people and over time and with the priorities of the evaluator. Key challenges for research into the well-being impacts of conservation interventions include the need to build up a collection of case studies so as to draw out generalizable lessons; harness the potential of modern technology to support well-being research; and contextualize evaluations of conservation impacts on well-being spatially and temporally within the wider landscape of social change. Pathways through the smog of confusion around the term well-being exist, and existing frameworks such as the Well-being in Developing Countries approach can help conservationists negotiate the challenges of operationalizing the concept. Conservationists have the opportunity to benefit from the recent flurry of research in the development field so as to carry out more nuanced and locally relevant evaluations of the effects of their interventions on human well-being.

Idea Bank: Lessons Learned From Test Writing  

NSDL National Science Digital Library

It is a passion for students' authentic engagement in science that influenced the author's decision to heed the Utah State Office of Education's (USOE) call for test writers at a professional workshop last summer. The workshop offered science teachers across the state of Utah the opportunity to craft test items used in Utah's state assessment, the Utah Criterion Referenced Tests. These test items capture the extent to which students are learning the Utah Core Curriculum (USOE 2003). He saw the USOE workshop as a chance to help shape items that would measure the kind of learning that is embedded in the lives of students and centers on inquiry experiences.

Landscape and vegetation change on the Iberian Peninsula during the Roman Epoch - A reconstruction based on Geo-Bioarchives  

NASA Astrophysics Data System (ADS)

Archaeological investigations expect that first strong landscape changes on the Iberian Peninsula based on Roman Occupation (Schattner 1998, Teichner 2007). Actual sedimentological investigations in flood plains, lagoons and estuaries do not reflect this development. They often show a decrease in sedimentation during this period (Thorndycraft & Benito 2006 a/b). In contrast analyses on sediments from roman dams (Hinderer et al. 2004, Solanas 2005) document massive erosion processes. The aim of this presented project is to reconstruct the effects of the roman land use system on vegetation and landscape development. Therefore different Geo-Bioarchives on several sites of Portugal and Spain - estuaries, palaeoriver channels and roman dams - are actually investigated with a high temporal resolution using palynological and sedimentological methods. First results show, that the anthropogenic impact starts clearly before roman time with an peak in human activity during Iron Age (Schneider et al. 2008). During the roman occupation phase different effects are visible. The inland areas document a massive increase in vegetation change, while the coastal areas were stronger developed before and show only slightly and very local changes in land use and vegetation.

Resolvendo a equao de Schrdinger atravs da substituio direta da srie de potncias  

E-print Network

This work presents a direct and highly accurate method to solve ordinary differential equations, in particular the Schr\\"odinger equation in one dimension, through the direct substitution of a power series solution to obtain a purely algebraical system containing the recurrence relations among the series coefficients. With these recurrence relations at hand it is possible to build an extremely simple routine using only basic arithmetic operations to find solutions of very high accuracy at a very low cost of machine resources. For the Schr\\"odinger equation the energy eigenvalues may be estimated by a very simple method, an this estimate may be easily refined using the recurrence relations until the specified tolerance has been reached, which allows one to find high accuracy wavefunctions even for states with very high quantum numbers. ----- Este trabalho apresenta um m\\'etodo direto e de alta acur\\'acia para resolver equa\\c{c}\\~oes diferenciais ordin\\'arias, em particular a equa\\c{c}\\~ao de Schr\\"odinger em uma dimens\\~ao, atrav\\'es da substitui\\c{c}\\~ao direta de uma solu\\c{c}\\~ao em s\\'erie de pot\\^encias para obter um sistema puramente alg\\'ebrico contendo as rela\\c{c}\\~oes de recorr\\^encia entre os coeficientes da s\\'erie.
