Bridging the survival gap for children with cancer, between those (the great majority) in low and middle income countries (LMIC) and their economically advantaged counterparts, is a challenge that has been addressed by twinning institutions in high income countries with centers in LMIC. The long-established partnership between a Central American consortium--Asociación de Hemato-Oncología Pediátrica de Centro América (AHOPCA)--and institutions in Europe and North America provides a striking example of such a twinning program. The demonstrable success of this endeavor offers a model for improving the health outcomes of children with cancer worldwide. As this remarkable enterprise celebrates its 15th anniversary, it is appropriate to reflect on its origin, subsequent growth and development, and the lessons it provides for others embarking on or already engaged in similar journeys. Many challenges have been encountered and not all yet overcome. Commitment to the endeavor, collaboration in its achievements and determination to overcome obstacles collectively are the hallmarks that stamp AHOPCA as a particularly successful partnership in advancing pediatric oncology in the developing world. © 2013 Wiley Periodicals, Inc.

Pregnant women with thromboembolic diseases, previous thrombotic episodes or thrombophilia family history were supervised in a multidisciplinary Obstetrics/ Hematology consultation in Centro Hospitalar São João EPE, Porto, Portugal. For the evaluation and medication of these women, a risk stratification scale was used. The aim of this study was to validate a Risk Stratification Scale and thromboprophylaxis protocol by means of comparing it with a similar scale, developed and published by Sarig. We have compared: The distribution, by risk groups, obtained through the application of the two scales on pregnant women followed at Centro Hospitalar São João, Porto, Portugal, consultation; the sensibility and specificity for each one of the scales (DeLong scale, applied to Receiver Operating Characteristic) curves; the outcomes in pregnancies followed in Hospital São João, Porto, PortugalResults: According to our Hema-Obs risk stratification scale, 29% were allocated to low-risk, 47% to high-risk and 24% to very-high-risk groups. According to Galit Sarig risk stratification scale, 24% were considered low-risk, 53% moderate, 16% high-risk and 7% as very high-risk group. In our study we observed 9% of spontaneous abortions, in comparison with 18% in the Galit Sarig cohort. From the application of Receiver Operating Characteristic curve to both risk stratification scales, the results of the calculated areas were 58,8% to our Hema-Obs risk stratification scale and 38,7% to Galit Sarig risk stratification scale, with a Delong test significancie of p = 0.0006. We concluded that Hema-Obs risk stratification scale is an effective support for clinical monitoring of therapeutic strategies.

Hace 80 años, la Escuela de Medicina de la Universidad Nacional, en voz de su director, Gustavo Baz Prada, hizo una propuesta que pronto se convirtió en realidad y finalmente en norma, la que desde entonces se conoce como SS. Esta iniciativa se vio como una manera para que los estudiantes de medicina del último año retribuyeran a la sociedad una parte de lo que esta invirtió en su educación, consolidaran su formación mediante la exposición a las realidades de todos los días en los medios más necesitados, se pusieran a prueba sobre sus verdaderas capacidades para atender pacientes y participaran en la solución de un problema de atención sanitaria que en ese entonces era mucho más apremiante que ahora. Unos años después, los recién egresados de otras licenciaturas (pasantes) también fueron incorporados a esta estrategia y, al fin, se reconoció formalmente como una responsabilidad de las instituciones educativas. Las aportaciones del SS a la salud de las personas y a la formación de los médicos han sido incuestionables, y la experiencia humana que ha representado para quienes lo han vivido ha dejado marcas indelebles.

This paper reviews medical activity provided from 1996 to 2000 by the International Radio Medical Centre (Centro Internazionale Radio Medico, C.I.R.M.). C.I.R.M. is a non-profit organization headquartered in Rome and providing freely telemedical advice to ships flying of any flag navigating on all seas of the world, to civil airplanes and to small Italian islands. From 1996 to 2000 C.I.R.M. has assisted 4,982 patients, 4,686 of which (94%) on board ships, 85 on airplanes and 206 on small Italian islands. More than 65% of requests of telemedical advice received by C.I.R.M. were from non-Italian ships. This indicates the really international nature of C.I.R.M.'s activity. The largest number of medical requests come from the Atlantic Ocean, followed by the Mediterranean sea, Indian Ocean and Pacific Ocean. In terms of pathologies assisted, accidents took the first place, followed as main pathologies by gastrointestinal disorders, cardiovascular pathologies, respiratory disorders, infectious and parasitic diseases and nervous system complaints. Analysis of the outcome of C.I.R.M.'s medical activity showed that more than 50% of patients assisted were recovered or improved while assisted by the Centre.

La fuerza influye directamente en el estado de salud y en la capacidad de fitness, motivo por el que el entrenamiento contra resistencias o resistance training (RT) se incluye dentro de aquellos programas de ejercicio encaminados a mejorar la salud y calidad de vida. Debido a que muchasenfermedades cursan con alteración de la masa y funcionalidad muscular y a que el RT es la principal modalidad de ejercicio encaminada a mejorar la función muscular, el objetivo de la presente revisión bibliográfica ha sido exponer las evidencias actuales sobre las adaptaciones delRT, así como su posible aplicación en patologías como la obesidad, diabetes, dislipemia, hipertensión, cáncer, Parkinson, esclerosis múltiple o fibromialgia. El RT en estas enfermedades puede aumentar los niveles de masa muscular, disminuyendo los niveles de masa grasa, los nivelesde ácidos grasos en sangre y la glucemia, incrementando la sensibilidad a la insulina, y disminuyendo los niveles de citokinas inflamatorias. El RT, además, mejora el gasto cardiaco y la funcionalidad endotelial, regulando la tensión arterial e incrementando el consumo de oxígeno. Las ganancias de fuerza muscular mejoran la funcionalidad y la calidad de vida, especialmente en población con una afectación neuromuscular grave, como pudieran ser los enfermos de esclerosis múltiple, fibromialgia o Parkinson. Por ello, el RT debe ser incorporado como parte del tratamiento en las personas que presentan determinado tipo de patologías.

CoMoS2/rGO/C3N4 ternary heterojunctions catalysts with high photocatalytic activity and stability for hydrogen evolution under visible light irradiation

Noble metal free MoS2/g-C3N4 catalyst has attracted intense attentions for visible light photocatalytic hydrogen evolution as a result of its earth abundance, low cost and unique heterojunctions stacked with two dimensional sheets. However, the low charge separation efficiency resulted from the poor conductivity of g-C3N4 and MoS2, and lack of abundant active sites from coordinative unsaturated atoms in MoS2, restricts the photocatalytic hydrogen evolution activity and stability enhancement of MoS2/C3N4 composite catalysts. Herein, CoMoS2/rGO/g-C3N4 catalysts with ternary heterojunctions are prepared by facile solvothermal method, which exhibit high visible light photocatalytic activity and stability for hydrogen evolution. The optimal hydrogen evolution rate of CoMoS2/rGO/g-C3N4 catalysts is 684 μmol g-1 h-1 when the content of CoMoS2 is 2% and the content of rGO is 0.5%. The stability of CoMoS2/rGO/C3N4 catalysts just decrease about 3% after 4 cycling runs for 16 h. The good catalytic performances of catalysts are attributed to the synergistic effect among the g-C3N4 nanosheets, rGO nanosheets and CoMoS2 nanosheets. The high conductivity of rGO nanosheets enhances the electron-hole separation and charge transfer, and Co doping increases the active sites for hydrogen evolution due to the increase of unsaturated atoms in CoMoS2 nanosheets.

Nosso principal objetivo é melhor caracterizar a população estelar dos braços espirais e de uma estrutura existente no centro galáctico que acreditamos ser devido à existência de uma barra, cujas extremidades estariam localizadas em longitudes galácticas l~23° e l~14°. As observações realizadas em vários filtros (imagens J, H e K) são particularmente importantes nas direções que tangenciam os braços espirais, desta forma, comparamos uma direção que atravessa um braço a uma direção próxima que não passa pelo braço, sendo que ambas possuem a mesma contribuição de contagens foreground. Nas missões realizadas até o presente, observamos a região na direção tangencial ao braço de Scuttum, com observações de l = 30.04° até l = 31.04°, a cada intervalo de longitude de 0.1°, para latitude galáctica de 0.0°, 0.25°, 0.50°. Para as regiões que acreditamos serem as extremidades da barra, observamos as faixas de longitude compreendidas entre -15° £ l £ -13° e 24° £ l £ 22° a cada intervalo de 0.25°, para latitude galáctica de 0.0° e 0.25°. As observações nos filtros J e H foram feitas com tempo de integração de 60s, na banda K, as observações foram feitas utilizando o filtro C1 com tempo de integração de aproximadamente 210 s (12x15s). Elaboramos diagramas cor-cor e cor-magnitude onde podemos verificar a existência de regiões com diferentes contagens e população estelar à medida que um braço espiral é atravessado.

Introducción: Las malformaciones del tubo neural (MTN) representan la segunda causa más frecuente de anomalías congénitas, luego de las cardiopatías. En este grupo se destaca el mielomeningocele (MMC) por su mayor incidencia, y por ser la más incapacitante y la más compleja entre todas las demás malformaciones del sistema nervioso c`entral (SNC). En Bolivia, como en muchos países de Sudamérica, los bajos niveles socio-culturales y la debilidad en el sistema sanitario, hacen que su incidencia y su morbilidad, sean mayores que en las naciones más desarrolladas. Material y Métodos: Se realizó un estudio retrospectivo y descriptivo de 70 casos de MMC, atendidos por un equipo multidisciplinario en el Hospital Universitario Japonés (HUJ) de Santa Cruz de la Sierra, entre 2008-2011. De ellos, 60 fueron intervenidos quirúrgicamente. Resultados: Se realizaron controles prenatales sólo en 27 mujeres (38.6%), diagnosticándose una disrafia espinal en apenas dos casos (7.4%). La edad de ingreso del MMC en su mayoría fue después de las 24 horas (65.6%), predominando su localización en la región lumbosacra (64.3%). De ellos, 67.2% eran abiertos, presentando un 32.9% un daño neurológico motor parcial mientras que 47.1% tenían paraplejia por debajo de la lesión. De los 70 casos, tres (4.3%) no fueron intervenidos, por presentar defectos congénitos severos o estado general grave. Las principales complicaciones posoperatorias inmediatas fueron: dehiscencia de sutura y/o infección de la herida (16.6%), fístula de líquido cefalorraquídeo (LCR) (10%) e infección del SNC (11.7%). La mortalidad general y postoperatoria fue de 7.1% y 3.3%, respectivamente. Al mes de vida presentaban hidrocefalia un 80% de los pacientes operados, colocándose una derivación ventriculoperitoneal (DVP) de presión media. De 9 pacientes que tuvieron un acompanamiento de dos o más años, seis presentaron una médula anclada, que fueron intervenidas quirúrgicamente. Conclusi

The sweat test (ST) measures chloride levels in sweat and is considered the gold standard for the diagnosis of cystic fibrosis (CF). However, the reliability of a ST depends on their being performed by experienced technicians and in accordance with strict guidelines. Our aim was to evaluate how sweat stimulation, sweat collection, and chloride measurement are performed at 14 centers (9 public centers and 5 private centers) that routinely perform STs in the state of São Paulo, which has the highest frequency of CF in Brazil. This was a cross-sectional cohort study, using a standardized questionnaire administered in loco to the staff responsible for conducting STs. No uniformity regarding the procedures was found among the centers. Most centers were noncompliant with the international guidelines, especially regarding the collection of sweat (the samples were insufficient in 10-50% of the subjects tested); availability of stimulation equipment (which was limited at 2 centers); modernity and certification of stimulation equipment (most of the equipment having been used for 3-23 years); and written protocols (which were lacking at 12 centers). Knowledge of ST guidelines was evaluated at only 1 center. Our results show that STs largely deviate from internationally accepted guidelines at the participating centers. Therefore, there is an urgent need for standardization of STs, training of qualified personnel, and acquisition/certification of suitable equipment. These are essential conditions for a reliable diagnosis of CF, especially with the increasing demand due to newborn screening nationwide, and for the assessment of a possible clinical benefit from the use of modulator drugs. O teste do suor (TS) mede os níveis de cloro no suor e é considerado o padrão ouro para o diagnóstico da fibrose cística (FC). Contudo, a confiabilidade do TS depende de sua realização por técnicos experientes e segundo diretrizes rígidas. Nosso objetivo foi avaliar como s

Em 2001, o Instituto Superior de Ciências Aplicadas (ISCA Faculdades de Limeira) iniciou um projeto pelo qual o Observatório do Morro Azul empreendeu uma parceria com o Centro de Promoção Social Municipal (CEPROSOM), instituição mantida pela Prefeitura Municipal de Limeira para atender crianças e adolescentes carentes. O CEPROSOM contava com dois projetos: Projeto Centro de Convivência Infantil (CCI) e Programa Criança e Adolescente (PCA), que atendiam crianças e adolescentes em Centros Comunitários de diversas áreas da cidade. Esses projetos têm como prioridades estabelecer atividades prazerosas para as crianças no sentido de retirá-las das ruas. Assim sendo, as crianças passaram a ter mais um tipo de atividade - as visitas ao observatório. Este painel descreve as várias fases do projeto, que envolveu: reuniões de planejamento, curso de Astronomia para as orientadoras dos CCIs e PCAs, atividades relacionadas a visitas das crianças ao Observatório, proposta de construção de gnômons e relógios de Sol nos diversos Centros Comunitários de Limeira e divulgação do projeto na imprensa. O painel inclui discussões sobre a aprendizagem de crianças carentes, relatos que mostram a postura das orientadoras sobre a pertinência do ensino de Astronomia, relatos do monitor que fez o atendimento no Observatório e o que o número de crianças atendidas representou para as atividades da instituição desde o início de suas atividades e, em particular, em 2001. Os resultados são baseados na análise de relatos das orientadoras e do monitor do Observatório, registros de visitas e matérias da imprensa local.

Resumen El estudio de la problemática relacionada con la infección de tuberculosis (TB) en la frontera México-Estadounidense implica la consideración de tres aspectos complejos y entrelazados: la TB, una entidad patológica que debido a sus características epidemiológicas y patogénicas, resulta difícil de seguir y atender de manera completa; la zona fronteriza, zona geográfica y epidemiológica que entrelaza dos naciones, dos culturas, dos sistemas de salud y leyes diferentes; además del estigma, que implica más que tratamientos clínicos y abordajes de categorías de riesgo debido a la condición social y bajo conocimiento. Este trabajo narra diez estrategias realizadas en México y la frontera México-Estadounidense del año 2006 al 2013 como un esfuerzo de ampliar la comprensión de este fenómeno social y de salud pública conformado por una infección, un entorno físico y personas, también de la identificación y aplicación de prácticas competentes de abogacía y movilización social. Los trabajos realizados y presentados dan a conocer diferentes intervenciones para generar adherencia al tratamiento, mitigar el estigma relacionado con la infección de TB, mejorar la atención centrada en la persona e informar la relevancia del abordaje micro y macro de la salud y el trabajador social.

El interés por comprender la co-morbilidad de la esquizofrenia y el trastorno en el uso de sustancias, ha aumentado debido al incremento de este diagnóstico, a los efectos negativos observados en el sujeto y a los costos en los servicios de salud. Este trastorno dual puede tener efectos dramáticos en el curso clínico del trastorno psicótico tales como: mayores recaídas, re-hospitalizaciones, síntomas más severos, no adherencia al tratamiento antipsicótico, cambios marcados del humor, aumento en el grado de hostilidad e ideación suicida, así como alteraciones en otras áreas del funcionamiento incluyendo violencia, victimización, indigencia y problemas legales. La literatura proveniente en particular de Estados Unidos y Europa sugiere que el rango de prevalencia para este diagnóstico puede oscilar entre el 10% hasta el 70%. En este estudio, revisamos la prevalencia del diagnóstico dual de esquizofrenia y trastorno en el uso sustancias, así como sus características sociodemográficas, con base en la literatura disponible alrededor del mundo dando énfasis en la poblacion latina. A pesar de que este diagnóstico es ampliamente aceptado, se conoce poco sobre su prevalencia en la población latina, sobre los factores ambientales, demográficos, clínicos y otras características de estos individuos. Un mejor conocimiento sobre este diagnóstico permitiría mejorar los métodos para la detección y adecuada valoración del trastorno en el uso de sustancias en personas con trastornos metales severos como la esquizofrenia.

Applying Human-Centered Design Methods to Scientific Communication Products

2016-12-01

Knowing your users is a critical part of developing anything to be used or experienced by a human being. User interviews, journey maps, and personas are all techniques commonly employed in human-centered design practices because they have proven effective for informing the design of products and services that meet the needs of users. Many non-designers are unaware of the usefulness of personas and journey maps. Scientists who are interested in developing more effective products and communication can adopt and employ user-centered design approaches to better reach intended audiences. Journey mapping is a qualitative data-collection method that captures the story of a user's experience over time as related to the situation or product that requires development or improvement. Journey maps help define user expectations, where they are coming from, what they want to achieve, what questions they have, their challenges, and the gaps and opportunities that can be addressed by designing for them. A persona is a tool used to describe the goals and behavioral patterns of a subset of potential users or customers. The persona is a qualitative data model that takes the form of a character profile, built upon data about the behaviors and needs of multiple users. Gathering data directly from users avoids the risk of basing models on assumptions, which are often limited by misconceptions or gaps in understanding. Journey maps and user interviews together provide the data necessary to build the composite character that is the persona. Because a persona models the behaviors and needs of the target audience, it can then be used to make informed product design decisions. We share the methods and advantages of developing and using personas and journey maps to create more effective science communication products.

The Centro Nazionale Terremoti (CNT - National Earthquake Center), departement of Istituto Nazionale di Geofisica e Vulcanologia (INGV), has designed and setup a rapid response emergency structure to face the occurrence of strong earthquakes. This structure is composed by a real time satellite telemetered temporary seismic network (see Abruzzese et al., 2009 Fall AGU) used to improve the hypocentral locations of the INGV National Seismic Network, a stand alone temporary seismic network whose goal is primarily the high dynamic/high resolution data acquisition in the epicentral area and a mobile operational center, the COES (Centro Operativo Emergenza Sismica, Seismological Emergency Operational Center). The COES structure is a sort of mobile office equipped with satellite internet communication that can be rapidly installed in the disaster area to support all the INGV staff operative needs and to cooperate with the Civil Protection department (DPC) aggregating all the scientific information available on the seismic sequence and providing updated information to Civil Protection for the decision making stage during the emergency. The structure is equipped with a heavy load trolley that carries a 6x6 inflatable tent, a satellite router, an UPS, computers, monitors and furniture. The facility can be installed in a couple of hours in the epicentral area and provides a full featured office with dedicated internet connection and VPN access to the INGV data management center in Rome. Just after the April 6 2009 Mw 6.3 earthquake in L’Aquila (Central Italy) the COES has been installed upon request of the Italian Civil Protection (DPC) in the DICOMAC (Directorate of Command and Control - which is the central structure of the DPC that coordinates the emergency activities in the areas affected by the earthquake) located in the Guardia di Finanza headquarters in Coppito nearby L'Aquila (the same location that hosted the G8 meeting).

Objective This study aimed to investigate the frequency of positive results for hepatitis B and C, HIV and syphilis in blood donations at the Centro Regional de Hemoterapia de Ribeirão Preto, to describe donors with positive results according to some demographic and socioeconomic variables, to identify risk factors associated to these donors and the reasons that they were not detected during clinical screening. Methods A descriptive study was performed between July 1st 2005 and July 31st 2006 by interviewing 106 donorsafter medical consultations where they were informed of positive results for hepatitis B, hepatitis C, HIV or syphilis. Results There was a predominance of first-time donors, males, under 50-year olds, married individuals, from Ribeirão Preto, with elementary education, low economic status and of people who donated at the request of friends or relatives. Hepatitis C was the most frequently detected infection (56.6%), followed by hepatitis B (20.7%), HIV (12.3%) and syphilis(10.4%). About 40% of donors had omitted risk factors for different reasons: because they trusted the results of serological tests, did not feel comfortable about talking of risk factors or did not consider them relevant. Other justifications were the duration of the interview, the interviewer was unskilled, embarrassment and doubts about confidentiality. Conclusion The results indicate the need for changes in the approach to clinical screening and a review of methods to attract and guide potential donors. PMID:23323063

Analizando los datos combinados de los relevamientos de HI de Hartmann & Burton (1997) y Arnal et.al (2000), hemos detectado la presencia de una estructura en forma de ``shell" en la denominada ``ventana de Puppis". Esta estructura, cuyo centro se encuentra en la dirección (l = 245 deg, b = -5 deg) tiene un diámetro angular de ˜ 18 deg y es detectada en el rango de velocidades (LSR) entre -9 y +6 km/seg. El análisis de los datos sugiere que esta estructura puede haberse originado en una perturbación en el denominado ``Feature A" de Lindblad (1973), a una distancia de 150-200 pc del Sol. Se determinaron parámetros tales como Masa y Energía Cinética del Shell y se analiza un posible origen del mismo.

Late Glacial to Holocene environmental variabilities: A new multi-proxy paleolimnological study of sedimentary sequences from Como (northern Italy)

Lake Como (northern Italy) is the deepest Italian lake, reaching a depth of about 425 m. The lambda-shaped lake expands about 45 km in NE-SW direction. Southwards of the hydrologically closed western branch, two sediment cores of 70 m (S1) and 65 m length (S2) were taken in the year 2005 close to the cathedral of Como (Piazza Verdi). The drilling sites are located in the middle of the Southern Alps, some 300 m from the present-day lakeshore. The cores provide the first detailed Late Glacial to Holocene multi-proxy record for the Lake Como basin. Our research is aimed at investigating the environmental and geological evolution of the Insubria Region. The multi-proxy study of the stratigraphic sequences contain geophysical, geotechnical, sedimentological, paleobotanical, and radiocarbon analyses. They have been performed for core S1 and are still in progress on core S2. With this data the working group focuses on two main issues. The first topic is the reconstruction of the natural and anthropogenic processes controlling the ground subsidence in the Como urban area (e.g., Comerci et al., 2007) and another aim is to reconstruct vegetation and land-use dynamics. In particular, 150 samples of vegetal macroremains have been collected in the palustrine deposits along S1 core, down to 31,00 m. Below this depth (dated 14C 12,496 ± 55 yr BP - 15,050 - 14,250 cal yr BP), the amount of plant macroremains in the sediment drops dramatically. The taxonomic determination was carried out on more than 800 macroremains. They are represented by fragments of wood, leaves, needles, seeds, fruits, mosses and tiny charcoals (Motella, 2009, unpublished PhD Thesis). Picea/Larix, Pinus sp., Juniperus with Betula, found in the deeper levels (30.80 - 30.00 m), are the first arboreal taxa that colonized the shores of Lake Como, and show that the reforestation began in this area about 16,000 years ago. During the early Holocene (25.10 m) Abies alba expanded and further upwards the sequence

SUMMARY The frequency of anti-Toxocara spp. antibodies in individuals attended by the Centro de Salud Familiar in the coastal Niebla town, Chile, was related to the host and to environmental factors. IgG anti- Toxocara antibodies were detected with a commercial ELISA kit (SCIMEDX Corporation, USA). Samples with undetermined absorbance values were subjected to an additional ELISA standardized by the Instituto de Salud Pública, Chilean Health Ministry, a commercial ELISA (NOVATEC, Germany), and a commercial Western blot kit (LDBio Diagnostics, France). Hematological exams were performed using an automated blood counter and blood smears. Dog feces were collected from the ground along the main road in Niebla, including rural and urban locations. Ninety (25.4%) of the 355 examined individuals were positive by the ELISA test. The frequency of anti-Toxocara antibodies and the infection risk were significantly higher (p < 0.05) among those individuals ≥ 40 years old with respect to the 20-39 years old group, in individuals from rural locations, those who did not have a safe drinking water supply in the house or who presented blood eosinophilia. The proportion of positive samples of dog feces and the mean number of Toxocara canis eggs/g of feces in urban and rural areas were similar (p > 0.05). PMID:27680167

Atualmente vivencia-se um mundo globalizado onde os computadores e a internet permitiram um acesso rápido e seguro a todo tipo de informação e conhecimento. O presente trabalho visa analisar a maneira pela qual alunos de segundo grau da rede estadual da cidade de São Paulo obtiveram, caso tenham, conhecimentos básicos de astronomia quanto aos fenômenos celestes que os rodeiam, tais como a sucessão dos dias e das estações do ano, além de questioná~los sobre fatos genéricos tais como: o que vem a ser o Sol, o Big Bang, o que ocasionou a extinção dos dinossauros. Para tanto foi elaborado um formulário constando de questões de múltipla escolha, o qual foi aplicado no primeiro colegial diurno da Escola Estadual Guilherme de Almeida. Num espaço amostral de 44 alunos constatou-se que 41% dos alunos adquiriram seus conhecimentos astronômicos na escola e 59% através da mídia em geral. Neste mesmo espaço amostral apenas 11% dos alunos usaram computadores na escola, 41% na residência, 5% no trabalho e 43% não utilizaram. O presente estudo revelou também que para 50% dos alunos o professor jamais utilizou um programa de computador a respeito de astronomia ou fez alguma apresentação sobre o tema. Embora em sua fase inicial este estudo revela claramente que a maioria dos alunos não obtém na escola seus conhecimentos astronômicos, estes provém de fontes não especificamente didático-pedagógicas tais como filmes e revistas populares que não raramente geram conhecimentos incompletos e em muitos casos inclusive falhos.

XAS Study at Mo and Co K-Edges of the Sulfidation of a CoMo / Al2O3 Hydrotreating Catalyst

Pichon, C.; Gandubert, A. D.; Legens, C.

2007-02-02

Because of its impact on environment, the removal of sulfur is an indispensable step, called hydrotreatment, in the refining of petroleum. One of the most commonly used hydrotreating catalysts is CoMo-type catalyst which is composed of molybdenum disulfide slabs promoted by cobalt atoms (CoMoS phase) and well dispersed on a high specific area alumina. As far as the highest sulfur content allowed in gasoline and diesel is continually decreasing, more and more efficient and active hydrotreating catalysts are required. In order to optimize the reactivity of the CoMo-type catalyst in hydrotreatment, a better understanding of the processes used to producemore » the active phase (CoMoS slabs) of the catalyst is necessary. The study reported here deals with the sulfiding mechanism of the slabs and the influence of temperature on the phenomenon. Ex situ X-ray absorption spectroscopy (XANES and EXAFS) was used to study the evolution of the structure of CoMo-type catalyst sulfided at various temperatures (from 293 to 873 K). XAS analysis was performed at both molybdenum and cobalt K-edges to obtain a cross-characterization of the sulfidation of the slabs. It evidenced the formation of various compounds, including two molybdenum oxides, MoS3 (or MoS3-like compound) and Co9S8, at specific steps of the sulfiding process. It showed the role of intermediate played by MoS3 (or MoS3-like compound) during the formation of the slabs and the competition between the appearance of promoted slabs (CoMoS phase) and Co9S8. At last, it leaded to the proposal of a mechanism for the sulfidation of the catalyst.« less

Introducción. La vulnerabilidad puede entenderse como la carencia de recursos materiales e inmateriales que impide el aprovechamiento de oportunidades en distintos aspectos de la vida. Estos recursos de bienestar evitan el deterioro de la calidad de vida.Objetivo. Construir un índice de vulnerabilidad con las características de los capitales físico, humano, social y funcional de los adultos mayores de tres ciudades de Colombia en el 2016, y determinar los factores asociados con esta condición.Materiales y métodos. Se hizo un estudio transversal con información primaria mediante 1.514 encuestas a personas de 60 años o más de Medellín, Barranquilla y Pasto. En la construcción del índice se usó el análisis factorial con los métodos de componentes principales y de rotación ortogonal varimax.Resultados. Las condiciones que generaban vulnerabilidad se relacionaron principalmente con el capital humano (calidad de vida, salud mental y hábitos); los demás capitales aportaron un solo componente, así: capital físico (ocupación), capital social (acompañamiento) y capital funcional (independencia funcional). La vulnerabilidad fue mayor en los residentes de Pasto. Los factores asociados con la vulnerabilidad fueron la ciudad de residencia, el sexo, el nivel educativo y el rol en el hogar.Conclusión. En el 58,55 % de las personas mayores, la vulnerabilidad se explicó por el uso del tiempo, la independencia funcional y el bienestar subjetivo. Estos hallazgos aportan elementos para el mejoramiento de la calidad de vida, principalmente en cuanto a la capacidad funcional para mantener la independencia, estar ocupados y fortalecer la salud mental.

Resumen: En este artículo presentamos el proyecto de capacitación llevado a cabo en comunidades de la sierra y costa de Oaxaca, México, desde 1991, por el Centro de Capacitación Integral para Promotores Comunitarios (CECIPROC). La decisión de hacer este trabajo en Oaxaca responde a que ese estado ocupa uno de los primeros lugares de marginación y de desnutrición en menores de 5 años. El objetivo es describir un modelo de capacitación y compartir parte de las experiencias derivadas, tanto del modelo como del trabajo realizado en las distintas áreas (nutrición y alimentación, salud comunitaria, ecología y etnobotánica, y educación y organización), por promotores mujeres y hombres en sus comunidades. La experiencia obtenida en 24 años muestra la factibilidad técnica y social del proyecto en el ámbito de la salud, el reconocimiento social del proyecto del CECIPROC como un organismo civil que ha aportado alternativas como solución a la problemática de salud, el hacer suyo el proyecto por algunos promotores y los diferentes obstáculos a los que se ha enfrentado. Enfatizamos el hecho de que la situación socioeconómica y política prevaleciente en el estado de Oaxaca es una limitante para el buen desarrollo de los programas colectivos de salud, e insistimos en la necesidad de compartir nuestras experiencias para que puedan ser utilizadas en la planificación y ejecución de otros proyectos.

Introducción: la hipercolesterolemia es uno de los principales factores de riesgo en la enfermedad cardiovascular. Los esteroles vegetales se han postulado como agentes reguladores y beneficiosos para el control de esta.Objetivo: analizar el efecto de los esteroles vegetales añadidos en una leche en la reducción del colesterol plasmático en adultos jóvenes.Métodos: ensayo clínico, controlado, aleatorizado, doble ciego y cruzado. Los esteroles (2,24 g diarios) fueron administrados en dos tomas de 350 ml de una leche comercial desnatada, durante dos periodos de 3 semanas, separados por una "fase de lavado" de 2 semanas, en el grupo experimental. Al grupo control se le administró la misma cantidad de leche desnatada, sin esteroles. Tanto al inicio como al final de cadaperiodo de intervención se extrajeron muestras sanguíneas. Se analizaron la composición corporal, hábitos de salud y los siguientes marcadores sanguíneos: perfil lipídico, hematológico, inflamación, etc.Resultados: se incluyeron 54 personas en el estudio con una edad media de 38,8 ± 7,3 años. La diferencia porcentual entre los marcadores basales y finales para el colesterol total, colesterol-LDL, colesterol-HDL, triglicéridos y colesterol no-HDL fueron del 9,73%, 12,5%, 1,9%, 3,15% y 13,2%, respectivamente. Se obtuvieron diferencias estadísticamente significativas entre el grupo experimental y el grupo control, para todos los marcadores analizados excepto para los triglicéridos.Conclusión: los esteroles vegetales suministrados en un alimento de consumo habitual, como la leche, pueden ser una estrategia terapéutica no farmacológica para el control de la hipercolesterolemia de alto interés sanitario.

Para a maioria dos estudantes, sua passagem pelo ensino formal fundamental envolve a transmissão de fatos que devem ser guardados para um exame, a habilidade para lembrar fórmulas e, eventualmente, a repetição de experimentos que devem produzir resultados exigidos pelo professor. O resultado deste modelo de ensino, ao longo dos anos, é conhecido por todos: desconhecimento e descontentamento, por parte dos estudantes, de temas relativos ao papel e aos processos da ciência. Acreditamos que a Astronomia, pelo seu caráter observacional, é uma das áreas do conhecimento que pode contribuir neste cenário. A Fundação Planetário da Cidade do Rio de Janeiro possui um telescópio Meade LX-200 (25cm) que, juntamente com as câmeras CCD ST-7E e ST8E, tem sido utilizado em projetos voltados aos estudantes do ensino médio desde o ano 2000. Tais projetos envolvem a condução de um projeto de pesquisa observacional num nível apropriado, e possibilitam o contato com técnicas e novas tecnologias: computador, software para manipulação de dados e gráficos, programas de tratamento e redução de dados, uso de equipamentos óptico-eletrônicos (telescópio e CCD), bem como o processo de aquisição de conhecimento. Dentro da proposta dos anos anteriores, priorizamos projetos de uma noite, ou seja, procuramos trabalhar com fenômenos que apresentem variabilidade com intervalo de recorrência relativamente curto. Em todos os casos, optamos pela fotometria diferencial, que tem se mostrado bastante eficiente para o céu luminoso como o da cidade do Rio de Janeiro. Neste painel, apresentamos alguns dos projetos desenvolvidos no último ano, com 25 estudantes.

this study was conducted to compare the quantity of intercondylar bone removed during femoral box osteotomy for implantation of three contemporary posterior stabilized (PS) total knee arthroplasty designs: Sigma PS (DePuy), Vanguard (Biomet) and Persona (Zimmer). we compared the maximum volumetric bone resection required for the housing of the PS mechanism of these three designs. Bone removal by each PS box cutting jig was three-dimensionally measured. The differences between the three designs were analyzed by the Kruskal-Wallis test. The Mann-Whitney U-test was used for pairwise comparisons. The level of significance was set at p<0.05. for small-size implants, the average box osteotomy volume of Persona was significantly smaller than the Vanguard and Sigma PS volumes (p=0.003). The mean difference between Vanguard and Sigma PS (p=0.01) was also significant. For medium size implants, the mean difference between Persona and Sigma PS (p=0.008) and the mean difference between Vanguard and Sigma PS (p=0.01) were statistically significant. For large size implants, the mean difference between Vanguard and Sigma PS (p=0.01) and the mean difference between Sigma PS and Persona (p=0.008) were statistically significant. irrespective of implant size, the Persona cutting jig always resected significantly less bone than did Vanguard and Sigma PS. although this study does not establish any clinical relevance of removing more or less bone at primary TKA, its results suggest that if a PS design is indicated, it is preferable to select a model which resects less distal femoral bone.

Among the several risks to which the terrestrial life is subject, there is a remote possibility of collision with minor astronomical bodies such as comets and asteroids, which can potentially cause consequences ranging from minor damages to large cataclysms with reflections for the whole Earth. The frequency of the collisions is smaller whenever the external bodies are bigger and more massive. It is possible to conduct simulations taking into account these factors and the velocities and angles of the collisions to estimate their probabilities, the consequences for our planet and the frequency of such events. The results of the simulations are presented graphically to facilitate the final analysis. Finally, we point out that there are several research centers in the world working in the surveillance of the sky to identify possible "aggressive" bodies and evaluate the actual risks for the planet.

Entre os muitos riscos que corre o ambiente terrestre, existe a possibilidade, ainda que remota, de choques com pequenos corpos celestes como cometas, asteróides e meteoróides que podem provocar desde pequenas colisões sem grandes conseqüências até cataclismos de enormes dimensões, com reflexos para toda a vida existente na Terra. A taxa das colisões, como era de se esperar, é tanto maior quanto menores forem as dimensões e a massa do corpo externo. É possível fazer simulações levando-se em conta o diâmetro médio do objeto celeste, sua densidade, a velocidade e o ângulo de colisão para estimar as conseqüências que trariam tais colisões. É possível também estimar ampère probabilidades dos choques e avaliar os reais riscos que nosso planeta corre e com que periodicidade podemos esperá-los. Os resultados dessas simulações aparecem em gráficos de modo a facilitar a analise final. Por fim, lembramos que existem centros de pesquisa em várias partes do mundo trabalhando no patrulhamento do céu na busca de

da Silva, L. A.; Voelzke, M. R.

2008-09-01

Este trabalho visa analisar a possibilidade de relacionar conteúdos aplicados no ensino fundamental e médio de forma interdisciplinar por intermédio da astronomia, com a intervenção de objetos de aprendizagem que possam integrar as disciplinas e a utilização de recursos tecnológicos. Em uma pesquisa prévia com 20 professores de uma escola estadual situada na cidade de Guarulhos foi observado que apenas 25% dos professores utilizam algum recurso tecnológico para o desenvolvimento de conteúdos pertinentes à sua disciplina, tais como sites e softwares educativos, sendo que a maioria absoluta continua ensinando apenas com livros didáticos. A maior parte dos professores apresenta dificuldades em trabalhar sua disciplina de forma interdisciplinar, ou seja, 75% dos professores preferem aplicar os conteúdos seguindo uma hierarquia linear de tópicos, evitando a discussão de temas que de alguma forma estão relacionados. A astronomia pode vir à fascinar o ser humano e despertar sua curiosidade promovendo um maior interesse no aprendizado, podendo favorecer análises interdisciplinares de forma lógica e objetiva, desta forma colocar a astronomia como tema motivador interdisciplinar, pode ser relevante no que se refere ao distanciamento da fragmentação dos conteúdos. No Estado de São Paulo, a implantação da proposta curricular no ensino fundamental e médio mostra claramente a inserção da astronomia na maior parte das séries, principalmente na 6ª série em que todo o bimestre se fala de astronomia.

algunos estudiantes sabían que un espectro puede estar formado por un prisma o red de difracción, la mayor parte de ellos desconocía la naturaleza de las líneas espectrales. A lo largo del curso, esta cuestión fue trabajada con un enfoque práctico mediante la observación del espectro solar y de las lámparas durante clases expositivas/dialogadas. Los resultados obtenidos en el curso mustran la importancia de los centros de ciencia como un apoyo en la educación formal. En este caso en particular, la Sala Solar del Observatorio Dietrich Schiel se destaca como un entorno favorable para la enseñanza de la física moderna en la escuela secundaria. Este trabalho analisa resultados obtidos em um curso sobre física solar para alunos do ensino médio promovido pelo Observatório Dietrich Schiel da USP. O curso foi elaborado pelos autores com a intenção de investigar concepções sobre o Sol, ensinar tópicos de física moderna relacionados ao Sol e conhecimentos gerais sobre o astro rei. A metodologia de coleta de dados consistiu em gravação em áudio e vídeo das aulas e das entrevistas semi-estruturadas, e respostas a questionários escritos. Os resultados mostraram que a maioria dos participantes concebeu o Sol como constituído por fogo e as manchas solares como buracos na superfície solar. Embora alguns alunos soubessem que um espectro pode ser formado por um prisma ou rede de difração, a maior parte deles desconhecia a natureza das linhas espectrais. Ao longo do curso, este tema foi trabalhado com uma abordagem prática com observação do espectro solar e de lâmpadas e em aulas expositivo-dialogadas. Os resultados obtidos no curso apontam para a importância dos centros de ciências como parceiros da educação formal. Neste caso específico, a Sala Solar do Observatório Dietrich Schiel é um ambiente propício para o ensino de física moderna no ensino médio.

Combined pollen, charcoal and modeling evidence from the Insubria Region suggests that fire was a major driver of late Holocene vegetation change. However, the extent and timing of fire response dynamics are not clear yet. We use lacustrine sediments from Lago di Como (N-Italy, S-Alps) to assess if the reconstructed vegetation and fire dynamics were relevant at large scales and if they coincided in time with those observed at smaller sites. The lake, due to its size (142 km2) and economic potential, was very attractive for early land use and human presence in this area is well documented since ca. 10,000 yrs ago (Mesolithic). We used pollen, plant macrofossils and charcoal to reconstruct the vegetation composition and fire activity. During the Younger Dryas and the Early Holocene until ca. 8000 cal BP natural dynamics prevailed. Subsequently, land use and slash-and-burn activities increased at the Mesolithic-Neolithic transition and became widespread around ca. 6500 cal BP. Microscopic charcoal and numerical analyses demonstrate that anthropogenic fires had a determinant influence on long-term vegetation dynamics at regional scales in Insubria. Microscopic charcoal and pollen and spores indicative of land use show that human pressure intensified after ca. 5300 cal yr BP and even more since ca. 4300 cal yr BP. Our results suggest that important species which disappeared or were strongly reduced by land use and fire (e.g. Abies alba, Tilia, Ulmus) will potentially reestablish in the Lago di Como area and elsewhere in Insubria, if land abandonment initiated in the 1950s will continue.

The main focus of this article is to present some impressions about the way some teachers appropriated of the tools from the ASTRONOMY TEACHING KIT (KITPEA). The subjects of this research were teachers that took part in the astronomy teaching specialization course offered by the Continuing Education Project (FOCO) at Math and Science Teaching Center (CECIMIG) from the School of Education of Federal University of Minas Gerais (FaE/UFMG). The data was collected with the use of a questionnaire and of an interview applied to these teachers. The analysis of the data was structured with the aid of the Activity Theory and the Mediated Action Theory. We interpret the teachers' speech using the constitutive aspects of the activity system and the concepts of appropriation and domain as an analytical device. It was possible to recognize the appropriation of the tools in 7 narratives among the 11 individuals who took part in the research. El objetivo principal de ese artículo es presentar indicaciones sobre la manera como algunos maestros se apropiaron de las herramientas del KIT PARA LA ENSEÑANZA DE LA ASTRONOMÍA (KITPEA).

to analyze whether the tutor's use of reflexive strategies encourages the students to reflect. The goal is to discover what type of strategies can help to achieve this and how tutors and students behave in the practical context. a qualitative and ethnographic focus was adopted. Twenty-seven students and 15 tutors from three health centers participated. The latter had received specific training on reflexive clinical tutoring. The analysis was developed through constant comparisons of the categories. the results demonstrate that the tutors' use of reflexive strategies such as didactic questioning, didactic empathy and pedagogical silence contributes to encourage the students' reflection and significant learning. reflexive practice is key to tutors' training and students' learning. analisar se o uso de estratégias reflexivas por parte da tutora de estágio clínico estimula a reflexão nos estudantes.

From Rome to Como: 20 years of active research on carbon-based electrodes for lithium batteries at INP-Grenoble

NASA Astrophysics Data System (ADS)

Yazami, Rachid

This paper reviews the main areas of research performed at different Laboratories of the Institut National Polytechnique de Grenoble (INPG) over the past 20 years, specifically on cabonaceous materials for electrode applications in lithium batteries. The most significant event was the discovery in the early 1980s of reversible lithium intercalation into graphite in polymer electrolytes, which led to the use of this material in today's lithium-ion batteries. Important work was also carried out on positive electrode for primary and secondary batteries, especially graphite oxide and graphite fluoride. Most of these results were presented at the 10 IMLB series Symposia, which started in Rome in 1982 and were back to Como, Italy, in 2000.

This article presents results of a research which aimed to understand the meanings that people construct for astronomical observation. The subjects, students and school teachers, initially received some instruction on how to view astronomical objects through the telescope. After the observation was realized, they were interviewed. The data analysis allowed the creation of 12 categories, later interpreted on the basis of relationship with knowledge (relation to the world, with himself and with others), as presented by Bernard Charlot.

La enumeración de la soltería femenina en los censos de población: sesgo y propuesta de corrección

McCaa, Robert; Esteve, Albert; Garcia, Joan

2013-01-01

Esta investigación tiene como objetivo investigar el efecto que la disolución de las uniones consensuales tiene en los niveles de soltería que proporciona el Censo de Población, niveles derivados de la variable estado civil. Para ello comparamos los datos censales con los de la Encuestas de Demografía y Salud (de ahora en adelante DHS) en aquellos países y años para los que disponemos de ambas fuentes en el mismo año o años adyacentes (Bolivia, Brasil, Colombia y Perú). Los resultados muestran claramente que las proporciones de nunca unidas derivadas de la variable censal ’Estado civil’ son sistemáticamente más elevadas que las estimadas a partir de las DHS. La razón de esta sobreestimación obedece al hecho de que personas que estuvieron en unión libre en el pasado se declaran solteras en el momento del Censo. La elevada proporción de mujeres solteras que tienen hijos según el Censo es una prueba de ello y a su vez una solución efectiva para corregir el sesgo. PMID:25593515

Influence of H 2O and H 2S on the composition, activity, and stability of sulfided Mo, CoMo, and NiMo supported on MgAl 2O 4 for hydrodeoxygenation of ethylene glycol

Dabros, Trine Marie Hartmann; Gaur, Abhijeet; Pintos, Delfina Garcia

Here in this work, density functional theory (DFT), catalytic activity tests, and in-situ X-ray absorption spectroscopy (XAS) was performed to gain detailed insights into the activity and stability of MoS 2, Ni-MoS 2, and Co-MoS 2 catalysts used for hydrodeoxygenation (HDO) of ethylene glycol upon variation of the partial pressures of H 2O and H 2S. The results show high water tolerance of the catalysts and highlight the importance of promotion and H 2S level during HDO. DFT calculations unraveled that the active edge of MoS 2 could be stabilized against SO exchanges by increasing the partial pressure of Hmore » 2S or by promotion with either Ni or Co. The Mo, NiMo, and CoMo catalysts of the present study were all active and fairly selective for ethylene glycol HDO at 400 °C, 27 bar H 2, and 550–2200 ppm H 2S, and conversions of ≈50–100%. The unpromoted Mo/MgAl 2O 4 catalyst had a lower stability and activity per gram catalyst than the promoted analogues. The NiMo and CoMo catalysts produced ethane, ethylene, and C1 cracking products with a C 2/C 1 ratio of 1.5–2.0 at 550 ppm H 2S. This ratio of HDO to cracking could be increased to ≈2 at 2200 ppm H 2S which also stabilized the activity. Removing H 2S from the feed caused severe catalyst deactivation. Both DFT and catalytic activity tests indicated that increasing the H 2S concentration increased the concentration of SH groups on the catalyst, which correspondingly activated and stabilized the catalytic HDO performance. In-situ XAS further supported that the catalysts were tolerant towards water when exposed to increasing water concentration with H2O/H2S ratios up to 300 at 400–450 °C. Raman spectroscopy and XAS showed that MoS2 was present in the prepared catalysts as small and highly dispersed particles, probably owing to a strong interaction with the support.

Morris, William Z; Gebhart, Jeremy J; Goldberg, Victor M; Wera, Glenn D

2016-07-01

A total knee arthroplasty system offers more distal femoral implant anterior-posterior (AP) sizes than its predecessor. The purpose of this study is to investigate the impact of increased size availability on an implant system's ability to reproduce the AP dimension of the native distal femur. We measured 200 cadaveric femora with the AP-sizing guides of Zimmer (Warsaw, IN) NexGen (8 sizes) and Zimmer Persona (12 sizes) total knee arthroplasty systems. We defined "size deviation" as the difference in the AP dimension between the anatomic size of the native femur and the closest implant size. We defined satisfactory reproduction of distal femoral dimensions as < 1 mm difference between the implant and native femur size. The NexGen system was associated with a mean 0.46 mm greater implant size deviation than Persona (p < 0.001). When using a 1 mm size deviation as a cutoff for satisfactory replication of the native distal femoral anatomy, 85/200 specimens (42.5%) were a poor fit by NexGen, but a satisfactory fit by Persona. Only 1/200 specimens (0.5%) was a poor fit by Persona, but a satisfactory fit by NexGen (p < 0.001). The novel knee system with 12 versus 8 sizes reproduces the AP dimension of the native distal femur more closely than its predecessor. Further study is needed to determine the clinical impact of these differences. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

Resumo Contexto O consumo de crack é um dos grandes desafios em saúde pública, e o uso dessa droga tem efeitos diretos na saúde de seus usuários. Objetivos Avaliar o perfil das alterações vasculares em pacientes com dependência de crack em Centro de Atenção Psicossocial para Álcool e Drogas (CAPS-AD) e observar os possíveis efeitos vasculares periféricos. Métodos Trata-se de um estudo observacional, descritivo, de corte transversal. Os pacientes da amostra foram submetidos a um questionário objetivo para avaliar questões demográficas, padrão de uso da droga, coexistência de diabetes melito, hipertensão arterial ou tabagismo, exame físico e ecográfico. Os dados foram sumarizados e analisados estatisticamente com teste qui-quadrado ou teste exato de Fisher. Resultados A média de idade da amostra foi de 33,29 (±7,15) anos, e 74% eram do gênero masculino. A média de idade de início de uso da droga foi de 23,4 (±7,78) anos, com tempo médio de uso de 9,58 (±5,64) anos. O consumo médio diário de pedras de crack foi de 21,45 (±8,32) pedras. A alteração de pulsos em membros inferiores foi mais frequente em mulheres. A prevalência do espessamento da parede arterial nos membros inferiores foi de 94,8%. O tempo de uso da droga apresentou associação estatística (p = 0,0096) com alteração do padrão de curva espectral das artérias dos membros inferiores. Conclusões Há alterações vasculares periféricas em usuários de crack. O tempo de uso da droga exerceu um maior impacto nesse sistema, o que sugere associação entre o uso do crack e a diminuição de fluxo arterial.

To analyze the use of nursing terminology as an instrument of the nursing work process in Collective Health. Exploratory case study. For data collection was conducted a group interview with 24 nurses working in health units of a municipality in south central Paraná, Brazil. Data were analyzed in the light of interdependence between the structural, particular and singular dimensions contained in the Theory of Nursing Praxis Intervention in Collective Health. The situations interfering with improper use were the lack of knowledge about the origin and purpose of terminology, lack of training, and non-mandatory use. Although the nursing terminology is used as an instrument in the nursing work process in collective health, it requires training to be recognized as a classification system. At the same time, institutional policies should be employed to ensure the effective use of these instruments. Analisar a utilização de terminologia de enfermagem como instrumento do processo de trabalho do enfermeiro em Saúde Coletiva. Estudo de caso exploratório. Para coleta de dados foi realizada entrevista em grupo com 24 enfermeiros que atuam nas unidades de saúde de um município no centro-sul do Paraná, Brasil. Os dados foram analisados à luz da interdependência entre as dimensões estrutural, particular e singular contidas na Teoria da Intervenção Práxica de Enfermagem em Saúde Coletiva. As situações que interferiram na utilização inadequada foram o desconhecimento sobre origem e finalidade da terminologia, a falta de treinamento e a não obrigatoriedade de uso. A terminologia de enfermagem, apesar de utilizada como instrumento no processo de trabalho de enfermeiros em Saúde Coletiva, necessita de capacitação para ser reconhecida como sistema classificatório. Ao mesmo tempo, políticas institucionais devem ser empregadas no intuito de garantir a efetiva utilização destes instrumentos.

The pathogenic persona of community associated oral streptococci

PubMed Central

Whitmore, Sarah E.; Lamont, Richard J.

2011-01-01

Summary The mitis group streptococci (MGS) are widespread in the oral cavity and are traditionally associated with oral health. However, these organisms have many attributes that contribute to the development of pathogenic oral communities. MGS adhere rapidly to saliva-coated tooth surfaces, thereby providing an attachment substratum for more overtly pathogenic organisms such as Porphyromonas gingivalis, and the two species assemble into heterotypic communities. Close physical association facilitates physiologic support, and pathogens such as Actinobacillus actinomycetemcomitans display resource partitioning to favour carbon sources generated by streptococcal metabolism. MGS exchange information with community members through a number of interspecies signaling systems including AI-2 and contact dependent mechanisms. Signal transduction systems induced in P. gingivalis are based on protein dephosphorylation mediated by the tyrosine phosphatase Ltp1, and converge on a LuxR-family transcriptional regulator, CdhR. Phenotypic responses in P. gingivalis include regulation of hemin uptake systems and gingipain activity, processes that are intimately linked to the virulence of the organism. Furthermore, communities of S. gordonii with P. gingivalis or with A. actinomycetemcomitans are more pathogenic in animal models than the constituent species alone. We propose that MGS should be considered accessory pathogens, organisms whose pathogenic potential only becomes evident in the context of a heterotypic microbial community. PMID:21635580

Personality and persona: personality processes in self-presentation.

PubMed

Leary, Mark R; Allen, Ashley Batts

2011-12-01

This article examines the role that personality variables and processes play in people's efforts to manage their public images. Although most research on self-presentation has focused on situational influences, people differ greatly in the degree to which they care about others' impressions of them, the types of impressions they try to convey, and their evaluations of their self-presentational effectiveness. Personality constructs such as public self-consciousness, approval motivation, and fear of negative evaluation are associated with the motive to manage one's impressions, and people who differ in self-disclosure and desire for privacy differentially reveal information about themselves to others. Other variables relating to people's self-concepts, interpersonal goals, and traits influence the construction of specific images. Finally, the extent to which people believe they are capable of making desired impressions influences their impression management strategies and how they respond to other people's evaluations. © 2010 The Authors.

Influence of the Additives and The pH On the Cobalt-Molybdenum (Co-Mo) Alloy Electrodeposited On n-TypeSilicon

NASA Astrophysics Data System (ADS)

Fekih, Z.; Ghellai, N.; Fortas, G.; Chiboub, N.; Sam, S.; Chabanne-sari, N. E.; Gabouze, N.

In this work, thin films of metal alloys (Co-Mo) have been electrodeposited onto silicon (Si) surface. The effects of two different additives (H3BO3 and Na2CO3) and the pH of the solution on the electrochemically deposited films (morphology, stochiometry…) have been investigated. The properties of the deposits were characterized by using X-Rays Diffraction (XRD), Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Spectroscopy (EDS). The results show that the morphology and the film composition depend on both the pH of the solution and the additives. The presence of boric acid favors the Mo deposition. Crack-free homogeneous deposits with a low percentage of molybdenum can be easily obtained from high pH bath. The deposits were shown to exhibits a good crystalline structure.

Les déformations eburnéennes de l'unité birrimienne de la comoé (côte d'ivoire)

NASA Astrophysics Data System (ADS)

Vidal, M.

The analysis of Eburnean strain fields in the Upper (?) Birrimian Comoé Unit shows four great stages of tectogenesis: an early cleavage subparallel to stratification which results from synkinematic granitoïd intrusions; a folding (N40°E to N60°E); a transcurrent faulting period, essentially ductile N-S sinistral; N120°E schistosity, and a N110°E transcurrent ductile sinistral (?) faulting phase. The importance of the sinistral N-S faulting system and, to a lesser extent, the N120°E schistosity direction, is shown. The probable rôle of these directions (particularly N-S) from Liberian to Upper Cretaceous is shown by the within-plate tectonic occurrences in the West-African craton.

The wounded male persona and the mysterious feminine in the poetry of James Wright: a study in the transformation of the self.

known about Wright's childhood to attempt to reconstruct such a trauma, and a definitive biography is long overdue. (Wright died in 1980). However, the concept of "soul murder" as used by Shengold (1989) with respect to psychological trauma does seem pertinent. For example, Wright's powerful identification with the downtrodden, and especially with certain murderers (Doty, Judas) echoes the paranoiac Schreber's identification with his abusive father as "soul murderer": "I, myself, have been 'represented' as the one who had committed soul murder" (Shengold, 1989, p. 22, quoting Schreber). Certainly, the theme of damage to the self is prominent in Wright, and the poet's striving for reparation, restitution, and the restoration of lost goodness is not only characteristic of Melanie Klein's "depressive position" (Segal, 1980, pp. 76-89), which she saw as a normal developmental process, but also of the character structures of profoundly traumatized individuals. In addition, the rapid, "leaping" shifts of imagery in Wright's poems bear some resemblance to the shifts in mood and the dissociated and "autohypnotic" states (Shengold, 1989, pp. 138-154) of posttraumatic stress and related disorders. However much that may be the case, Wright's work moves toward healing and integration, and forces us to reconsider the psychoanalytic shibboleth that all that represents a lack of distinctiveness between self and other is pathological. This assumption denies the richness of that part of the psyche which originates in the symbiotic union of mother and infant. Wright's work does not so much force us to doubt our own perceptions of reality as it gently yet forthrightly guides us into other realms where feeling and thought are in dialogue, where the uniquely human and the universal mythos converge, and where--perhaps most importantly--possibility and transformation are imminent. The abandoned male persona and the mysterious feminine are part of that world, that cosmos, that Wright has cr

RESUMEN El estigma relacionado al VIH/SIDA continúa afectando la prestación de servicios de salud y el bienestar físico y mental de las personas con VIH/SIDA (PVS). Recientemente la literatura científica ha señalado la importancia de comprender las manifestaciones de estigma más allá de las interacciones individuales. Por tal razón, investigaciones recientes en y fuera de Puerto Rico enfatizan la importancia de entender cómo factores socio-estructurales (FSE) influyen en los procesos de estigmatización social. Con el propósito de examinar los FSE que influyen en las manifestaciones de estigma relacionado al VIH/SIDA, realizamos y analizamos nueve grupos focales compuestos por hombres y mujeres en tratamiento para el VIH/SIDA que habían tenido experiencias estigmatizantes. Los participantes identificaron FSE relacionados a las manifestaciones de estigma, tales como el uso de viviendas especializadas, descentralización de los servicios de salud y el desarrollo de protocolos administrativos excluyentes en los servicios de salud. Los resultados demuestran la importancia de considerar los FSE en el desarrollo e implementación de intervenciones dirigidas a la población. PMID:24639599

One of the greatest environmental and social-economics threats is climate change. This topic, in the next few years, will have a significant impact on the availability of water resources of many regions. This is compounded by the strong anthropization of water systems that shows an intensification of conflicts for water resource exploitation. Therefore, it is necessary a sustainable manage of natural resources thorough knowledge of the hosting territories. The development of investigation and data processing methods are essential to reduce costs for the suitable use and protection of resources. Identify a sample area for testing the best approach is crucial. This research aims to find a valid methodology for the characterization, modeling and management of subalpine urban aquifers, and the urban district of Como appears perfect. The city of Como is located at the southern end of the western sector of Lake Como (N Italy). It is a coastal town, placed on a small alluvial plain, therefore in close communication with the lake. The plain is drained by two streams, which are presently artificially buried, and have an underground flow path in the urban section till the mouth. This city area, so, is suitable for this project as it is intensely urbanized, its dimensions is not too extensive and it is characterized by two aquifers very important and little known. These are a shallow aquifer and a deep aquifer, which are important not only for any water supply, but also for the stability of the ground subsidence in the city. This research is also the opportunity to work in a particular well-known area with high scientific significance; however, there is complete absence of information regarding the deep aquifer. Great importance has also the chosen and used of the more powerful open source software for this type of area, such as PHREEQC, EnvironInsite, PHREEQE etc., used for geological and geochemical data processing. The main goal of this preliminary work is the

Estimación de pequeñas perturbaciones en satélites geocéntricos como un problema inverso

El movimiento geocéntrico de un satélite artificial es simulado automáticamente por un sistema de ecuaciones diferenciales de segundo orden que incluyen dos funciones perturbadoras. La primera representa el segundo término del potencial gravitatorio de la Tierra y la segunda corresponde al frenado atmosférico. Asumiendo como conocidas, por hipótesis o por mediciones, la posición y velocidad del satélite en instantes sucesivos se estiman las perturbaciones a intervalos sucesivos por un método determinístico. Para ilustrar el método y comprobar la precisión de nuestros resultados hemos simulado dos ejemplos incluyendo valores conocidos de las perturbaciones que luego comparamos con los resultados de nuestro método. El método puede aplicarse por ejemplo para el intervalo de una revolución satelital lo cual permitiría el diseño inmediato de una maniobra correctiva de la órbita satelital.

Resumo A pancreatite crônica é uma enfermidade associada a diversas complicações vasculares, como pseudocisto hemorrágico, trombose do sistema venoso portal e formações varicosas e pseudoaneurismáticas. O pseudoaneurisma de aorta abdominal secundário à pancreatite crônica é uma complicação rara, de difícil suspeição clínica, que requer tratamento complexo. A fisiopatologia dessa condição envolve a corrosão enzimática tecidual após a liberação e ativação de enzimas exócrinas proteolíticas das células acinares do pâncreas. O presente estudo relata o caso de um paciente de 52 anos, etilista crônico, internado com dor abdominal difusa, cuja propedêutica revelou se tratar de um pseudoaneurisma em aorta infrarrenal. Optou-se pelo tratamento cirúrgico convencional, levando-se em consideração a idade, as condições clínicas do paciente e a disponibilidade de endopróteses compatíveis com o diâmetro da aorta.

RESUMEN En México, las transferencias formales e informales destinadas al apoyo de las personas adultas mayores son diversificadas. En este documento se analizan la tendencia nacional y los resultados de un estudio centrado en la entidad federativa de Guanajuato. La distribución de los apoyos confirma que las transferencias hechas por el sistema de seguridad social tienen un sesgo urbano y que las transferencias formales del gobierno federal se orientan a las áreas menos urbanizadas, particularmente las zonas rurales. A pesar de las transferencias formales (esporádicas e insuficientes), las necesidades económicas y de salud de las personas mayores persisten y ello lleva a que sus familiares realicen transferencias informales de naturaleza ascendente. En México —y más concretamente en Guanajuato— el apoyo de quienes residen con la persona mayor tiene un significativo peso, y lo contrario sucede con el de quienes han migrado. A partir de este material, se analiza el rol que, de acuerdo a su cohorte y su condición migratoria, desempeñan los descendientes. En todo caso, queda de manifiesto que, en cada entidad nacional, las dinámicas de transferencias intergeneracionales son de diversos tipos. PMID:29375179

Despite DDT and PCB having been banned for about 40 years, they are still detectable in the environment. In the present research we specifically investigated the trophic transfer of these organochlorine contaminants (OC) through a pelagic food web of a deep lake in Northern Italy (Lake Como) over time. Zooplankton and fish were sampled each season of a year and OC concentrations and the carbon and nitrogen isotopic ratios were measured. By using stable isotopes, the direct trophic relationship between pelagic zooplankton and zooplanktivorous fish was confirmed for Alosa agone only in summer. Based on this result, the biomagnification factor normalized on the trophic level (BMF TL ) for organic contaminants was calculated. BMF TL values were within the range 0.9-1.9 for DDT isomers and 1.6-4.9 for some PCB congeners (PCB 95, PCB 101, PCB 149, PCB 153, PCB 138 - present both in zooplankton and in fish and representing >60% of the PCB contamination), confirming the biomagnification of these compounds in one of the two zooplanktivorous fish species of the lake.

In this paper we describe the development and dissemination of a film-based educational intervention to reduce negative attitudes towards gay and bisexual men and transgender women (GBT) and people living with HIV/AIDS (PLWHA) in Latino communities, with a focus on youth. The intervention, Tal Como Somos/Just as We Are, is based on stigma and attribution theories, extensive formative research, and community input. Evaluation findings among educators and school youth suggest the film has the potential to effectively impact attitudes towards GBT and PLWHA. The film and intervention are being disseminated using diffusion of innovations theory through community-based organizations, schools, television broadcasting and film festivals. PMID:24377496

Declarative Consciousness for Reconstruction

Existing information technology tools are harnessed and integrated to provide digital specification of human consciousness of individual persons. An incremental compilation technology is proposed as a transformation of LifeLog derived persona specifications into a Canonical representation of the neocortex architecture of the human brain. The primary purpose is to gain an understanding of the semantical allocation of the neocortex capacity. Novel neocortex content allocation simulators with browsers are proposed to experiment with various approaches of relieving the brain from overload conditions. An IT model of the neocortex is maintained, which is then updated each time new stimuli are received from the LifeLog data stream; new information is gained from brain signal measurements; and new functional dependencies are discovered between live persona consumed/produced signals

O universo em que vivemos possui segredos jamais imaginados pelo homem, fruto da pequena proporção que ocupamos diante de um cosmos infinito. A astronomia funciona como um instrumento que sacia a sede humana em desvendar esses segredos, estudando as galáxias, quasares, pulsares além da existência de todos os elementos que preenchem o espaço cósmico, o vácuo, não mais vazio como se pensou em outros tempos. A mídia explora esse campo de forma mística e também científica. A difusão adequada e dentro dos padrões educacionais vigentes, de conceitos astronômicos, se faz necessária, devido sua presença nos conteúdos escolares, centros de ciência e na mídia, de modo geral. A reforma do Currículo Básico da Escola Pública da maioria dos Estados brasileiros introduziu conceitos astronômicos desde a pré-escola até o Ensino Médio. Num estudo realizado com 1.032 alunos do Ensino Médio de seis escolas estaduais, revelou-se através da aplicação de um questionário que abordava conheciment os básicos em astronomia, como estes foram adquiridos e qual era a infra-estrutura oferecida pela escola: para 66,2% dos entrevistados o professor já fez alguma apresentação a respeito de astronomia. O presente estudo revelou também que 44,5% dos alunos entrevistados adquiriram seus conhecimentos astronômicos na escola, 28,1% através da televisão e 27,4% afirmaram que seus conhecimentos foram obtidos através de outros tipos de mídia (internet, filmes e revistas). Embora o estudo revele claramente que há certo equilíbrio na forma em que os alunos obtiveram seus conhecimentos astronômicos, a mídia ainda explora e muitas vezes desperta o interesse pela astronomia com assuntos que não fazem parte de nosso cotidiano como, por exemplo, o homem na Lua, os projetos espaciais e a primeira viagem de um astronauta brasileiro no espaço. Porém, em certos casos, a mídia pode promover conhecimentos incompletos ou mesmo equivocados sobre os conceitos que envolvam

This volume of Journal of Physics: Conference Series contains selected articles by the participants at the International Conference on Control and Synchronization of Dynamical Systems (CSDS-2005) organized by Centro de Investigaciones en Optica (CIO) in cooperation with the Society for Industrial and Applied Mathematics (SIAM), which was held in Leon, Guanajuato, Mexico on 4-7 October 2005. CSDS-2005 featured the latest research in nonlinear dynamics concentrating on the theory of control and synchronization of complex systems and its applications in different areas of science and engineering, including optics, electronics, mechanics, chemistry, medicine, economy, communication, etc. The conference brought together leading researchers, both theoreticians and experimentalists, from different fields of science and provided an excellent opportunity for sharing ideas and problems among specialists in controlling dynamical systems and synchronization. The meeting served a dual purpose: to expose the scientific community to the cutting edge of forefront research done by leaders in this area from as many as 25 countries and to attract the attention of Mexican researchers to this field of science. These proceedings are intended to be a record of this conference and to serve as a reference for future research which the conference hopes to have initiated. After the pioneering work on controlling chaos of E Ott, C Grebogi and J Yorke appeared in Physical Review Letters in 1990, the number of works on this topic grew tremendously. Our extensive bibliographic search among 110 peer reviewed journals yielded more than 1500 papers on controlling chaos and more than 2500 on synchronization of chaotic systems published during the last decade. The numbers of publications are still at their peaks that began to saturate, in 1998 and 2003, respectively. It is my pleasure to acknowledge the contribution of the program and organizing committees, the funding agencies and cooperating

La comunicación entre padres/madres y adolescentes sobre el tema de la sexualidad es importante para el desarrollo de la salud de personas jóvenes. Dicha comunicación puede verse negativamente impactada por actitudes estigmatizantes hacia el tema del VIH/SIDA. El objetivo de este estudio fue identificar actitudes estigmatizantes hacia el VIH/SIDA entre padres/madres y adolescentes puertorriqueños/as. Este esfuerzo es parte del Proyecto Cuídalos, dirigido a probar una intervención en formato electrónico que busca aumentar la comunicación sobre sexualidad y salud entre padres/madres y adolescentes mediante un diseño experimental con 458 diadas de padres/madres y adolescentes de 13 a 17 años. Para propósitos de este artículo reportamos estadísticas descriptivas sobre estigma hacia el VIH/SIDA con la información recopilada en la medición basal. Tanto adultos/as como adolescentes mostraron actitudes estigmatizantes hacia el VIH/SIDA. A la luz de los resultados es necesario continuar desarrollando intervenciones para la reducción de estigma en esta población. Los/as padres/madres pueden ser un recurso invaluable para reducir el estigma en los/as jóvenes, y prevenir conductas sexuales de riesgo e infecciones. PMID:27099649

Resumen Introducción: Los aneurismas asociados a malformaciones arteriovenosas (MAV) son lesiones vasculares que suelen encontrarse hasta en el 15% de los casos, incrementando el riesgo global de hemorragia. La conducta frente a los aneurismas asociados es dicotómica en la literatura, mientras existen reportes de la desaparición de los mismos luego de la exéresis de la MAV, otros artículos enfatizan su tratamiento precoz. El síndrome del acento extranjero es un raro trastorno neurológico en el que el paciente habla su lengua materna como lo haría una persona extranjera y suena con “acento” extranjero a oídos de los oyentes nativos. Objetivo: Presentar un paciente que desarrolla el síndrome del acento extranjero posterior a la exéresis de una MAV y la evolución de un aneurisma asociado. Presentación de caso: Paciente pediátrico que luego de la exéresis de una MAV fronto-opercular posterior izquierda remite por completo un aneurisma de hiperflujo asociado, presentando en el postquirúrgico el síndrome del acento extranjero. Conclusión: Queda reportado el caso de este raro síndrome y la resolución espontánea de un aneurisma proximal luego de la exéresis de una MAV. PMID:28480115

O problema quase bicircular planar consiste na determinação da dinâmica de um corpo, de massa desprezível, que se move sob o campo gravitacional de três corpos. No caso estudado, o quarto corpo é considerado um satélite artificial e os demais são a Terra, a Lua e o Sol, formando o sistema de três corpos. Este modelo permite a construção de uma hamiltoniana similar a do problema restrito de três corpos (PRTC), incluindo termos periódicos não autônomos, provenientes da presença do Sol, portanto pode ser entendido como uma perturbação ao PRTC. Suas órbitas periódicas aparecem isoladas e possuem o mesmo período solar. Os pontos de equilíbrio colineares possuem o mesmo caráter de estabilidade linear dos pontos lagrangianos (L1, L2 e L3) do PRTC, sendo do tipo sela x centro x centro, instável na direção x e estáveis nas direções y e z. As órbitas periódicas tridimensionais ao redor do ponto colinear é chamada órbita Halo. O objetivo deste trabalho é determinar órbitas de transferências de baixo consumo de combustível para um veículo espacial partindo de uma órbita de estacionamento ao redor da Terra em direção a uma órbita Halo do ponto L1, situado entre a Terra e Lua. Esta tarefa pode ser transformada no problema de valor de contorno: dado um ponto inicial na órbita de estacionamento, um ponto final na órbita halo e o tempo de transferência, deseja-se obter a trajetória que liga estes dois pontos e que minimize os incrementos de velocidade do veículo. Essas transferências são realizadas baseadas no método de Lambert e analisadas de modo a fornecer um baixo consumo. Posteriormente, é feita uma comparação de consumo com as órbitas de transferência equivalentes do PRTC.

Given the current concern about multiresistance to drugs in tuberculosis, the data from a large study in two different centers are presented. At the Hospital Universitario Reina Sofía de Córdoba 71,359 clinical isolates of Mycobacterium tuberculosis were processed and at the Centro de Referencia de Micobacterias 2,350 cultures were studied. The percentage of total multiresistance at the Hospital Universitario was 6% from 1996-1998, and 6.7% at the Centro de Referencia in 1998. Although these figures are high, they are lower than in previous years and could indicate the beginning of a decreasing trend, following years of increasing in the 1990s.

Modelo analítico del efecto de PRS sobre satélites GPS

NASA Astrophysics Data System (ADS)

Meza, A.; Brunini, C.; Usandivaras, J. C.

El sistema GPS (Global Position System) es, hoy en día, la herramienta de navegación y posicionamiento más potente y lo será sin duda en la próxima década. Gran parte de su valiosa utilidad se debe a la alta precisión que permite lograr y ésta, a su vez, depende, entre otras causas, de la precisión con que se conocen las órbitas de los satélites. La presión de radiación solar (PRS) fija el límite de la precisión con que pueden calcularse en la actualidad las efemérides satelitarias. El objetivo de este trabajo es proponer una mejor resolución de este fenómeno. El modelo analítico aquí presentado, se basa en el análisis del comportamiento de los residuos de un ajuste por mínimos cuadrados en el que se utiliza el modelo de PRS propuesto por Beutler. El mismo consiste en un modelo determinista del fenómeno con dos parámetros libres. Los resultados obtenidos ponen de manifiesto que, aún después de aplicar dichos parámetros, prevalecen en los residuos efectos semidiurnos en las componentes radial,tangencial y normal. Estos resultados obtenidos se comparan con los de un trabajo desarrollado por el Instituto de Berne (Beutler et al., 1994), en el que se utilizaron como pseudo-observaciones las órbitas precisas del IGS (CODE). El intervalo de integración escogido por este centro fueron las semanas 680 y 681. En resumen se tienen arcos de 14 días para todos los satélites, donde las efemérides precisas de los mismos para los 14 días fueron utilizados como pseudo-observaciones. El modelo de fuerza que empleó dicho centro fue básicamente el tradicional en lo que respecta al modelo de las fuerzas gravitacionales, y para la PRS utilizo el modelo standard de Beutler. Los parámetros de este modelo junto con las 6 condiciones iniciales (posición y velocidad) fueron ajustados por el método general de mínimos cuadrados. Los residuos en la componente radial, tangencial y normal, para los satélites con un buen comportamiento, presentan una

Introducción: ante las nuevas implicaciones atribuidas a la vitamina D y la asociación con enfermedades tales como el cáncer, diabetes, enfermedades cardiovasculares, autoinmunes y mortalidad, no es de extrañar que se haya defendido la medición de los niveles de vitamina D en la población general. Sin embargo, no existen datos experimentales que demuestren la viabilidad y rentabilidad de la estrategia de cribado en la población y tampoco se ha comprobado la existencia de beneficios para la salud, por lo que en la actualidad solo es aconsejable la medida de 25 (OH) vitamina D en los grupos de personas de alto riesgo como indican las guías clínicas internacionales.Objetivos: analizar las peticiones de vitamina D comprobando si se adecuan a las guías clínicas.Métodos: realizamos un estudio descriptivo transversal en el Área de Salud de Badajoz (España) estudiando las peticiones de determinación de vitamina D durante 12 meses consecutivos (n = 3.907). En dicho estudio revisamos el diagnóstico de petición y la historia clínica del paciente para discriminar entre peticiones que se adecuaban a las guías clínicas y peticiones injustificadas. Por último, realizamos el estudio económico.Resultados: en nuestros resultados encontramos que casi un tercio de peticiones no se adecuaban a las guías clínicas, en patologías tales como diabetes, dislipemias e hipertensión en las que no está recomendada la medición de los niveles de vitamina D, por lo que suponía un exceso de gasto para el sistema sanitario. Gasto que se incrementa cada año, tanto es así que se ha producido un aumento en las peticiones de más del 1.000% en los últimos 6 años.Conclusiones: concluimos la necesidad de crear protocolos de petición de vitamina D que se ajusten a las guías clínicas hasta que existan más estudios experimentales sobre las nuevas implicaciones de la vitamina D y así conseguir una correcta utilización de los recursos económicos del hospital.

to describe the coping of stoma patients with the news about the ostomy, as well as to analyze the meaning and the experience of their new bodily reality. qualitative phenomenological study undertaken through semistructured interviews with 21 stoma patients. The analysis was based on the constant comparison of the data, the progressive incorporation of subjects and triangulation among researchers and stomal therapy nurses. The software Atlas.ti was used. two main categories emerge: "Coping with the news about receiving a stoma" and "Meaning and experience of the new bodily reality". The informants' answer varies, showing situations that range from the natural acceptance of the process to resignation and rejection. The previous experiences of other family members, the possible reconstruction of the stoma or the type of illness act as conditioning factors. the coping with the news about the stoma is conditioned by the type of illness, although the normalization of the process is the trend observed in most informants. Nursing plays a fundamental role in the implementation of cognitive-behavioral interventions and other resources to promote the patients' autonomy in everything related to care for the stoma. descrever o enfrentamento de pessoas ostomizadas diante da notícia da realização do estoma, assim como analisar o significado e a vivência diante de sua nova realizada corporal. estudo qualitativo fenomenológico mediante entrevistas semiestruturadas com 21 personas ostomizadas.

Caring is considered as the essence of nursing. Underpinning caring, the internal regulation of emotions or the emotional labour of nurses is invisible. The concept of emotional labour is relatively underdeveloped in nursing. A literature search using keywords 'emotional labour', 'emotional work' and 'emotions' was performed in CINAHL, psycINFO and REPERE from 1990 to January 2008. We analysed 72 papers whose main focus of inquiry was on emotional labour. We followed Rodgers' evolutionary method of concept analysis. Emotional labour is a process whereby nurse adopt a 'work persona' to express their autonomous, surface or deep emotions during patient encounters. Antecedents to this adoption of a work persona are events occurring during patient-nurse encounters, and which consist of three elements : organization (i.e.social norms, social support), nurse (i.e.role identification, professional commitment, work experience and interpersonal skills) and job (i.e.autonomy, task routine, degree of emotional demand, interaction frequency and work complexity). The attributes of emotional labour have two dimensions : nurses' autonomous response and their work persona strategies (i.e. surface or deep acts). The consequences of emotional labour include organizational (i.e.productivity, 'cheerful environment') and nurse aspects (i.e. negative or positive) the concept of emotional labour should be introduced into preregistration programmes. Nurses also need to have time and a supportive environment to reflect, understand and discuss their emotional labour in caring for 'difficult' patients to deflate the dominant discourse about 'problem' patients.

2015-11-30

Three of the fundamental catalytic limitations that have plagued the electrochemical production of hydrogen for decades still remain: low efficiency, short lifetime of catalysts and a lack of low-cost materials. Here, we address these three challenges by establishing and exploring an intimate functional link between the reactivity and stability of crystalline (CoS 2 and MoS 2) and amorphous (CoS x and MoS x) hydrogen evolution catalysts. We propose that Co 2+ and Mo 4+ centers promote the initial discharge of water (alkaline solutions) or hydronium ions (acid solutions). We establish that although CoS x materials are more active than MoSmore » x they are also less stable, suggesting that the active sites are defects formed after dissolution of Co and Mo cations. Finally, by combining the higher activity of CoS x building blocks with the higher stability of MoS x units into a compact and robust CoMoS x structure, we are able to design a low-cost alternative to noble metal catalysts for efficient electrocatalytic production of hydrogen in both alkaline and acidic environments.« less

Sexually transmitted diseases are a significant public health problem. Within the Madrid Autonomous Region, the districts with the highest syphilis and gonorrhea incidences are part of the same Public Health Service (Servicio de Salud Pública del Área 7, SSPA 7). The objective of this study was to identify, by spatial analysis, clusters of syphilis and gonorrhea infections in this SSPA in Madrid. All confirmed syphilis and gonorrhea cases registered in SSPA 7 in Madrid were selected. Moran's I was calculated in order to identify the existence of spatial autocorrelation and a cluster analysis was performed. Clusters and cumulative incidences (CI) per health zone were mapped. The district with most cases was Centro (CI: 67.5 and 160.7 per 100.000 inhabitants for syphilis and gonorrhea, respectively) with the highest CI (120.0 and 322.6 per 100.000 inhabitants) in the Justicia health zone.91.6% of all syphilis cases and 89.6% of gonorrhea cases were among men who have sex with men (MSM). Moran's I was 0.54 and 0.55 (p=0.001) for syphilis and gonorrhea, respectively. For syphilis, a cluster was identified including the six health zones of the Centro district, with a relative risk (RR)of 6.66 (p=0.001). For gonorrhea, a cluster was found including the Centro district, three health zones of the Chamberí district and one of Latina (RR 5.05; p=0.001). Centro was the district with most cases of syphilis and gonorrhea and the most affected population were MSM. For both infections, clusters were found with an important overlap. By identifying the most vulnerable health zones and populations, these results can help to design public health measures for preventing sexually transmitted diseases.

Protecting the self: a descriptive qualitative exploration of how registered nurses cope with working in surgical areas.

PubMed

Mackintosh, Carolyn

2007-08-01

This paper aims to explore and describe how qualified nurses working with in, in-patient surgical areas cope with the daily experiences they are exposed to. It has long been recognised that many aspects of nursing work can result in high levels of stress, with negative consequences for the individual nurse and patient care. Difficulties in coping with nursing work can also result in burnout, as well as raising concerns about cognitive dissonance, emotional labour and the use of emotional barriers. Why some nurses are more prone to experience these phenomena than others, is unclear. A descriptive qualitative approach is taken using a purposive, theoretically congruent sample of 16 qualified registered nurses all of whom participated in a semi-structured interview during 2002. All interviews were tape recorded and transcribed verbatim and then analysed using the four stages outlined by Morse and Field [Morse, J.M., Field, P.A., 1996. Nursing Research: The Application of Qualitative Approaches. Chapman & Hall, London]. Three key themes emerged from analysis; relationships with patients, being a person and the effect of experience. All three interlink to describe a process whereby the individual switches off from the environment around them by adopting a working persona which is different but related to their own personal persona and is beneficially enhanced as a consequence of experience. Working as a nurse results in exposure to potentially distressing and stressful events from which it is important to protect the self. Participants in this study achieve protection by the development of a working persona which facilitates switching off and is beneficially enhanced by experience.

How Do Management Fees Affect Retirement Wealth under Mexico's Personal Retirement Accounts System?

Aguila, Emma; Hurd, Michael D; Rohwedder, Susann

2014-12-01

In 1997, Mexico transformed its pay-as-you-go social security system to a fully funded system with personal retirement accounts, including management fees. This article examines changes in retirement wealth resulting from this new system. It shows that management fees have drained a significant proportion of individuals' retirement wealth and have increased the number of persons claiming a government-subsidized minimum pension, particularly from the time the system was introduced in 1997 until adjustment to management fees in 2008. Since 2008, retirement wealth accumulation has been similar to that of the previous system. En 1997, México transformó su sistema de pensiones basado en cotizaciones individuales a uno de ahorro para el retiro que incluyen cuotas por la administración de las cuentas. El presente estudio examina los cambios en el monto de las pensiones como resultado de la introducción del nuevo sistema. Los resultados muestran que las cuotas de administración han drenado una proporción significativa del ahorro para el retiro de los individuos por lo que ha aumentado el número de personas que solicita la pensión mínima garantizada subsidiada por el gobierno desde que se introdujo el sistema en 1997 hasta que se hicieron ajustes en las cuotas de administración de los fondos de pensiones en 2008. A partir de 2008, la acumulación del ahorro para el retiro ha sido similar que la del sistema anterior.

In 1997, Mexico transformed its pay-as-you-go social security system to a fully funded system with personal retirement accounts, including management fees. This article examines changes in retirement wealth resulting from this new system. It shows that management fees have drained a significant proportion of individuals' retirement wealth and have increased the number of persons claiming a government-subsidized minimum pension, particularly from the time the system was introduced in 1997 until adjustment to management fees in 2008. Since 2008, retirement wealth accumulation has been similar to that of the previous system. En 1997, México transformó su sistema de pensiones basado en cotizaciones individuales a uno de ahorro para el retiro que incluyen cuotas por la administración de las cuentas. El presente estudio examina los cambios en el monto de las pensiones como resultado de la introducción del nuevo sistema. Los resultados muestran que las cuotas de administración han drenado una proporción significativa del ahorro para el retiro de los individuos por lo que ha aumentado el número de personas que solicita la pensión mínima garantizada subsidiada por el gobierno desde que se introdujo el sistema en 1997 hasta que se hicieron ajustes en las cuotas de administración de los fondos de pensiones en 2008.

El telescopio UNAM2l2, del Observatorio Astronómico Nacional, situado en la Sierra de San Pedro Mártir (Baja California, México), cumplira en un futuro muy cercano siete años de uso para fines de investigación astronómica. Aunque en este tiempo no se ha efectuado un estudio sistemático acerca de su comportamiento óptico y de los factores que influyen en la calidad de las imágenes, se han realizado pruebas diversas, estudios parciales y reuniones especificas, cuyos resultados no siempre se han difundido ampliamente y generalmente no se han presentado por escrito. Es por ello que hemos creido necesario intentar una recopilación de la información existente para poder con ella establecer un diagnóstjco que, aunque no sea definitivo, sirva de base para futuros trabajos tendientes a optimizar el comportamiento óptico del telescopio. Es evidente que un buen número de las conclusiones que se presentan son resultado del trabajo de muchas personas ó de esfuerzos colectivos. Asimismo, hemos tratado de localizar información bibliográfica que pueda ser de utilidad. Nuestro objetivo primordial ha consistido en centrarnos en la óptica del telescopio y su calidad, pero también se han considerado otros aspectos que puedan afectar las imágenes obtenidas tales como: celda del primario, `seeing' local y externo, flexiones posibles en la estructura mecánica del telescopio, etc.

Las lesiones traumáticas de la columna cervical son infrecuentes en los niños, representando el 1% de las fracturas pediátricas y el 2% de todas las lesiones raquídeas.Es importante conocer que la columna cervical en la infancia presenta variaciones anatómicas que en ocasiones pueden interpretarse como patológicas ya que en los niños una adecuada exploración física muchas veces puede ser complicada.El objetivo de este caso clínico es mostrar un hallazgo radiológico fisiológico de la columna cervical infantil que tiende a ser malinterpretado como patológico: la pseudosubluxación C2-C3.Se presenta un caso de un niño de 5 años de edad que acude a urgencias de traumatología pediátrica de nuestro centro por dolor cervical tras caída desde un tobogán. Se realizan radiografías cervicales de urgencias observando una disrupción de la línea cervical anterior y posterior entre C2 y C3. Una adecuada anamnesis junto con un meticuloso examen clínico y radiológico permite su correcto diagnostico sin necesidad de otras pruebas complementarias. La pseudoluxación anterior de C2 sobre C3 se puede estar presente en el 40% de los niños menores de 8 años. Este hallazgo puede diferenciarse de la luxación traumatic valorando la línea espinolaminar o línea de Swischuk, línea entre el borde anterior de las apófisis espinosas de C1 a C3. La interpretación adecuada de las radiografías de la columna cervical en la infancia requiere del conocimiento de estas variantes radiológicas y de las peculiares características de este segmento vertebral en la edad pediátrica.

Heterologous embryo transfer: Magisterial answers and metaphysical questions.

PubMed

Accad, Michel

2014-02-01

The debate regarding the morality of heterologous embryo transfer (HET) as a solution for the fate of cryopreserved embryos remains active. This paper endeavors to show that the magisterial instructions on bioethical issues can only lead to the conclusion that HET is always morally illicit. I begin by showing that the text of Dignitas personae recognizes HET as a procedure accomplishing a procreative function, and I indicate that it is through gestation that this procreative function occurs. I further show that the previous Instruction, Donum vitae, implicitly points to an ontological or spiritual consideration at play during gestation. This consideration is likely related to the procreative function identified in Dignitas personae. Finally, I place these two textual arguments in the context of the debate concerning HET and conclude that metaphysical questions must be clarified in order for the immorality of HET to be understood from a suitable anthropological perspective and gain more widespread acceptance.

Subsequently, the safety of existing precast concrete building is needed to be analyzed because these buildings were designed using BS 8110 which did not include the seismic loading in the design. Thus, this paper emphasizes on the seismic performance and dynamic behavior of precast school building constructed in Malaysia under three selected past earthquakes excitations ; El Centro 1940 North-South, El Centro East-West components and San Fernando 1971 using RUAUMOKO 2D program. This program is fully utilized by using prototype precast school model and dynamic non-linear time history analysis. From the results, it can be concluded that two-storey precast school building has experienced severe damage and partial collapse especially at beam-column joint under San Fernando and El Centro North-South Earthquake as its exceeds the allowable inter-storey drift and displacement as specified in Eurocode 8. The San Fernando earthquake has produced a massive destruction to the precast building under viscous damping, ξ = 5% and this building has generated maximum building displacement of 435mm, maximum building drift of 0.68% and maximum bending moment at 8458kNm.

Quantitative study, with aretrospective exploratory design, and descriptive statistical analysis of the ICU prescriptions of a teaching hospital from March to June 2014. The sample consisted of 319 prescriptions and subsamples of 50 prescriptions. The mean number of drugs per patient was 9.3 records, and a higher probability of drug interaction inherent to polypharmacy was evidenced. The study identified severe drug interactions, such as concomitant administration of Tramadol with selective serotonin reuptake inhibitor drugs (e.g., Metoclopramide and Fluconazole), increasing the risk of seizures due to their epileptogenic actions, as well as the simultaneous use of Ranitidine-Fentanyl®, which can lead to respiratory depression. A previous mapping of prescriptions enables the characterization of the drug therapy, contributing to prevent potential drug interactions and their clinical consequences.

San Antonio College is the oldest, largest and centrally-located campus of Alamo Colleges, a network of five community colleges based around San Antonio, Texas with a headcount enrollment of approximately 20,000 students. The student population is diverse in ethnicity, age and income; and the Colleges understand that they play a salient role in educating its students on the foreseen impacts of climate change. This presentation will discuss the key investment Alamo Colleges has adopted to incorporate sustainability and climate science into non-traditional classrooms. The established courses that cover climate-related course material have historically had low enrollments. One of the most significant challenges is informing the student population of the value of this class both in their academic career and in their personal lives. By hosting these lessons in hands-on simulations and demonstrations that are accessible and understandable to students of any age, and pursuing any major, we have found an exciting way to teach all students about climate change and identify solutions. San Antonio College (SAC) hosts the Bill R. Sinkin Eco Centro Community Center, completed in early 2014, that serves as an environmental hub for Alamo Colleges' staff and students as well as the San Antonio community. The center actively engages staff and faculty during training days in sustainability by presenting information on Eco Centro, personal sustainability habits, and inviting faculty to bring their classes for a tour and sustainability primer for students. The Centro has hosted professors from diverse disciplines that include Architecture, Psychology, Engineering, Science, English, Fine Arts, and International Studies to bring their classes to center to learn about energy, water conservation, landscaping, and green building. Additionally, Eco Centro encourages and assists students with research projects, including a solar-hydroponic project currently under development with the support

A good patient? How notions of 'a good patient' affect patient-nurse relationships and ART adherence in Zimbabwe.

While patient-provider interactions are commonly understood as mutually constructed relationships, the role of patient behaviour, participation in interactions, and characteristics, particularly ideals surrounding notions of 'good' and 'bad' patients, are under-examined. This article examines social representations of 'a good patient' and how these representations affect patient-healthcare provider relationships and antiretroviral treatment (ART) for people living with HIV. Using thematic network analysis, we examined interview and focus group transcripts involving 25 healthcare staff, 48 ART users, and 31 carers of HIV positive children, as well as field notes from over 100 h of ethnographic observation at health centres in rural Zimbabwe. Characteristics of a good patient include obedience, patience, politeness, listening, enthusiasm for treatment, intelligence, physical cleanliness, honesty, gratitude and lifestyle adaptations (taking pills correctly and coming to the clinic when told). As healthcare workers may decide to punish patients who do not live up the 'good patient persona', many patients seek to perform within the confines of the 'good patient persona' to access good care and ensure continued access to ART. The notion of a 'good ART patient' can have positive effects on patient health outcomes. It is one of the only arenas of the clinic experience that ART patients can influence in their favour. However, for people not conforming to the norms of the 'good patient persona', the productive and health-enabling patient-nurse relationship may break down and be detrimental to the patient. We conclude that policy makers need to take heed of the social representations that govern patient-nurse relationships and their role in facilitating or undermining ART adherence.

Combined experimental and numerical approach to evaluate impact scaling relations and reproducibility of craters produced at the Experimental Projectile Impact Chamber (E.P.I.C., Centro de Astrobiología, Spain.)

NASA Astrophysics Data System (ADS)

Ormö, J.; Wünnemann, K.; Collins, G.; Melero Asensio, I.

2012-04-01

The Experimental Projectile Impact Chamber at Centro de Astrobiología, Spain, consists of a 7m wide, funnel-shaped test bed, and a 20.5mm caliber compressed N2 gas gun. The test bed can be filled with any type of target material, but is especially designed for wet target experiments. The shape and size aim to decrease disturbance from reflected surface waves in wet target experiments. Experiments are done under 1Atm pressure. The gas gun can launch projectiles of any material and dimensions <20mm (smaller diameters using sabots), and at any angle from vertical to near horizontal. The projectile velocities are of the order of a few hundreds of meters per second depending mainly on the gas pressure, as well as projectile diameter and density. When using a dry sand target a transient crater about 30cm wide is produced. Wet target experiments have not yet been performed in this newly installed test chamber, but transient cavities in water are expected to be in the order of 50-70cm wide. The large scale allows for detailed study of the dynamics of cratering motions during the stages of crater growth and subsequent collapse, especially in wet targets. These observations provide valuable benchmark data for numerical simulations and for comparison with field studies. Here we describe the results of ten impact experiments using three different gas pressures (100bar, 180bar, 200bar), two projectile compositions (20mm, 5.7g delrin; 20mm, 16.3g Al2O3), and two different impact angles (90˚ and 53˚ over the horizontal plane). Nine of the experiments were done in a quarter-space geometry using a specially designed camera tank with a 45mm thick glass window. One experiment was done in half-space geometry as reference. The experiments were recorded with a high-speed digital video camera, and the resulting craters were documented with a digital still frame camera. Projectile velocities are estimated with a combination of tracking software and a Shooting Chrony Alpha M-1

2017-06-20

Unique characteristics of nursing homes (NHs) contribute to high rates of inappropriate antibiotic use for asymptomatic bacteriuria (ASB), a benign condition. A mobile clinical decision support system (CDSS) may support NH staff in differentiating urinary tract infections (UTI) from ASB and reducing antibiotic days. We used Goal-Directed Design to: 1) Characterize information needs for UTI identification and management in NHs; 2) Develop UTI Decide, a mobile CDSS prototype informed by personas and scenarios of use constructed from Aim 1 findings; 3) Evaluate the UTI Decide prototype with NH staff. Focus groups were conducted with providers and nurses in NHs in Denver, Colorado (n= 24). Qualitative descriptive analysis was applied to focus group transcripts to identify information needs and themes related to mobile clinical decision support for UTI identification and management. Personas representing typical end users were developed; typical clinical context scenarios were constructed using information needs as goals. Usability testing was performed using cognitive walk-throughs and a think-aloud protocol. Four information needs were identified including guidance regarding resident assessment; communication with providers; care planning; and urine culture interpretation. Design of a web-based application incorporating a published decision support algorithm for evidence-based UTI diagnoses proceeded with a focus on nursing information needs during resident assessment and communication with providers. Certified nursing assistant (CNA) and registered nurse (RN) personas were constructed in 4 context scenarios with associated key path scenarios. After field testing, a high fidelity prototype of UTI Decide was completed and evaluated by potential end users. Design recommendations and content recommendations were elicited. Goal-Directed Design informed the development of a mobile CDSS supporting participant-identified information needs for UTI assessment and communication

From Management to Negotiation: Technical and Institutional Innovations for Integrated Water Resource Management in the Upper Comoé River Basin, Burkina Faso

NASA Astrophysics Data System (ADS)

Roncoli, Carla; Kirshen, Paul; Etkin, Derek; Sanon, Moussa; Somé, Léopold; Dembélé, Youssouf; Sanfo, Bienvenue J.; Zoungrana, Jacqueline; Hoogenboom, Gerrit

2009-10-01

This study focuses on the potential role of technical and institutional innovations for improving water management in a multi-user context in Burkina Faso. We focus on a system centered on three reservoirs that capture the waters of the Upper Comoé River Basin and servicing a diversity of users, including a sugar manufacturing company, a urban water supply utility, a farmer cooperative, and other downstream users. Due to variable and declining rainfall and expanding users’ needs, drastic fluctuations in water supply and demand occur during each dry season. A decision support tool was developed through participatory research to enable users to assess the impact of alternative release and diversion schedules on deficits faced by each user. The tool is meant to be applied in the context of consultative planning by a local user committee that has been created by a new national integrated water management policy. We contend that both solid science and good governance are instrumental in realizing efficient and equitable water management and adaptation to climate variability and change. But, while modeling tools and negotiation platforms may assist users in managing climate risk, they also introduce additional uncertainties into the deliberative process. It is therefore imperative to understand how these technological and institutional innovations frame water use issues and decisions to ensure that such framing is consistent with the goals of integrated water resource management.

This instrument was built by the Instituto de Astronomia UNAM in Mexico City and the Centro de Ingenieria y Desarrollo Industrial (CIDESI) in Queretaro, Qro under a GRANTECAN contract after an international public bid. Some optical components were built by Centro de Investigaciones en Optica (CIO) in Leon Gto and the biggest mechanical parts were manufactured by Vatech in Morelia Mich. In this paper we made a general description of the CI and we relate how this instrument, build under international standards, was entirely made in Mexico.

Effects of coarse-graining on the scaling behavior of long-range correlated and anti-correlated signals.

PubMed

Xu, Yinlin; Ma, Qianli D Y; Schmitt, Daniel T; Bernaola-Galván, Pedro; Ivanov, Plamen Ch

2011-11-01

We investigate how various coarse-graining (signal quantization) methods affect the scaling properties of long-range power-law correlated and anti-correlated signals, quantified by the detrended fluctuation analysis. Specifically, for coarse-graining in the magnitude of a signal, we consider (i) the Floor, (ii) the Symmetry and (iii) the Centro-Symmetry coarse-graining methods. We find that for anti-correlated signals coarse-graining in the magnitude leads to a crossover to random behavior at large scales, and that with increasing the width of the coarse-graining partition interval Δ, this crossover moves to intermediate and small scales. In contrast, the scaling of positively correlated signals is less affected by the coarse-graining, with no observable changes when Δ < 1, while for Δ > 1 a crossover appears at small scales and moves to intermediate and large scales with increasing Δ. For very rough coarse-graining (Δ > 3) based on the Floor and Symmetry methods, the position of the crossover stabilizes, in contrast to the Centro-Symmetry method where the crossover continuously moves across scales and leads to a random behavior at all scales; thus indicating a much stronger effect of the Centro-Symmetry compared to the Floor and the Symmetry method. For coarse-graining in time, where data points are averaged in non-overlapping time windows, we find that the scaling for both anti-correlated and positively correlated signals is practically preserved. The results of our simulations are useful for the correct interpretation of the correlation and scaling properties of symbolic sequences.

Camões e a cosmogonia

NASA Astrophysics Data System (ADS)

Costa, J. M.

2003-08-01

Os Lusíadas, escrito por Luis de Camões em 1572, é um poema épico renascentista e a visão Cosmogônica do autor é apresentada, principalmente, no último canto do poema, quando Tétis mostra ao Gama a Máquina do Mundo. A Cosmogonia de Camões neste poema reflete uma visão de uma época de transição, que ainda não incorporou os elementos da revolução Copernicana. É uma visão Grego- Ptolomaica e também medieval. O poeta guia-se pela tradução e notas feita por Pedro Nunes, inventor do Nonio, do Tratado da Esfera "De Sphaera" do Astrônomo Inglês John Holywood, mais conhecido pelo nome latinizado de Johannes Sacrobosco. Outra provável fonte de Camões, de acordo com Luciano Antonio Pereira da Silva em Astronomia de os Lusíadas, é o "Theoricae novae Planetarum" (1460) do astrólogo Alemão Jorge Purbáquio (1423 - 1461). A Astronomia de Os Lusíadas representa a ciência do tempo de Camões. Camões nunca emprega a palavra constelação e seu catálogo é bastante completo. A Máquina do Mundo tem a Terra no centro. Em redor, em círculos concêntricos, a lua (Diana), Mercúrio, Vênus, o Sol (Febo), Marte, Júpiter e Saturno. Envolvendo estes astros tem o firmamento seguido pelo "Céu Áqueo" ou cristalino, depois o 1o Móbil, esfera que arrasta todas as outras consigo. Este trabalho, multidisciplinar, serve tanto para ensinar aos alunos da Física como das Ciências Humanas, a concepção de mundo do renascimento de uma forma belamente poética em versos decassílabos Este trabalho também ajuda na apreciação do maior clássico da língua portuguesa e mostra como as Ciências e as artes, em geral, estão correlacionadas e refletem a visão de mundo da época em que foi produzida.

Social Representations of Gynecologic Cancer Screening Assessment a Qualitative research on Ecuadorian women.

PubMed

Godoy, Yolanda; Godoy, Clara; Reyes, Juan

2016-06-01

The purpose of this work was to explore: knowledge, attitudes, and beliefs regarding gynecologic cancer screening on Ecuadorian women users of primary care facilities, to identify the social representations that users of health services make about these programs and their influence on the decision to undergo a screening. An exploratory and qualitative research design was held using focus groups and in-depth interviews for data collection. A narrative content analysis of the results was conducted. Women's knowledge on gynecological cancer screening was confusing. Most frequent misconceptions related to the pap smear were: the belief that it could be useful for detecting pregnancy, ovarian cysts or infections. Most of the participants stated that the pap smear procedure is a traumatic and painful experience. Regarding to mammography women said it was used for sick woman and this procedure by itself may cause cancer. El propósito de esta investigación fue explorar los conocimientos, actitudes y creencias respecto a los programas de detección del cáncer ginecológico entre usuarias de centros de atención primaria de salud para identificar las representaciones sociales que las usuarias de los servicios de salud elaboran acerca de estos programas y de los diferentes procedimientos que comprenden. El diseño de la investigación fue exploratorio y cualitativo, mediante grupos focales y entrevistas a profundidad, con el respectivo análisis narrativo e interpretativo del contenido. Se encontró conocimiento confuso acerca de los programas de tamizaje de cáncer ginecológico y dificultades asociadas a la realización de los procedimientos. Los significados más frecuentes acerca de los programas fueron: el uso de la citología cérvico-vaginal para detectar embarazo, quistes ováricos o infecciones. La mayoría de los participantes asociaba este procedimiento con una experiencia dolorosa y traumática. Respecto al autoexamen de mamas, lo calificaron como un masaje

The individual in mainstream health economics: a case of Persona Non-grata.

PubMed

Davis, John B; McMaster, Robert

2007-09-01

This paper is motivated by Davis' [14] theory of the individual in economics. Davis' analysis is applied to health economics, where the individual is conceived as a utility maximiser, although capable of regarding others' welfare through interdependent utility functions. Nonetheless, this provides a restrictive and flawed account, engendering a narrow and abstract conception of care grounded in Paretian value and Cartesian analytical frames. Instead, a richer account of the socially embedded individual is advocated, which employs collective intentionality analysis. This provides a sound foundation for research into an approach to health policy that promotes health as a basic human right.

Multidrug-resistant tuberculosis (MDR-TB) is a serious public health problem, but the new drugs bedaquiline (BDQ) and delamanid offer hope to improve outcomes and minimise toxicity. In Khayelitsha, South Africa, patients are routinely started on BDQ in the out-patient setting. This report from the field describes BDQ use in the out-patient setting at the Nolungile Clinic. The clinic staff overall report a positive experience using the drug. Challenges have been based largely on the logistics of drug supply and delivery. BDQ can be started successfully in the out-patient setting, and can be a positive experience for both patients and providers. La tuberculose multirésistante (TB-MDR) est un problème de santé publique grave, mais les nouveaux médicaments que sont la bédaquiline (BDQ) et le délamanide apportent un espoir d'améliorer les résultats tout en réduisant la toxicité. A Khayelitsha, Afrique du Sud, les patients démarrent leur traitement par BDQ en consultation externe en routine. Ce rapport du terrain décrit l'utilisation de la BDQ à la consultation externe du dispensaire Nolungile. Dans l'ensemble, le personnel du centre de santé exprime une expérience positive du médicament. Les défis ont surtout été liés à la logistique de l'approvisionnement et de la distribution du médicament. La BDQ peut être mise en route avec succès dans le cadre d'une consultation externe et peut constituer une expérience positive pour les patients et les prestataires de soins.

2017-01-01

In this paper, a data compression technology-based intelligent data acquisition (IDAQ) system was developed for structural health monitoring of civil structures, and its validity was tested using random signals (El-Centro seismic waveform). The IDAQ system was structured to include a high-performance CPU with large dynamic memory for multi-input and output in a radio frequency (RF) manner. In addition, the embedded software technology (EST) has been applied to it to implement diverse logics needed in the process of acquiring, processing and transmitting data. In order to utilize IDAQ system for the structural health monitoring of civil structures, this study developed an artificial filter bank by which structural dynamic responses (acceleration) were efficiently acquired, and also optimized it on the random El-Centro seismic waveform. All techniques developed in this study have been embedded to our system. The data compression technology-based IDAQ system was proven valid in acquiring valid signals in a compressed size.

Comprehending how visual context influences incremental sentence processing: insights from ERPs and picture-sentence verification

PubMed Central

Knoeferle, Pia; Urbach, Thomas P.; Kutas, Marta

2010-01-01

To re-establish picture-sentence verification – discredited possibly for its over-reliance on post-sentence response time (RT) measures - as a task for situated comprehension, we collected event-related brain potentials (ERPs) as participants read a subject-verb-object sentence, and RTs indicating whether or not the verb matched a previously depicted action. For mismatches (vs matches), speeded RTs were longer, verb N400s over centro-parietal scalp larger, and ERPs to the object noun more negative. RTs (congruence effect) correlated inversely with the centro-parietal verb N400s, and positively with the object ERP congruence effects. Verb N400s, object ERPs, and verbal working memory scores predicted more variance in RT effects (50%) than N400s alone. Thus, (1) verification processing is not all post-sentence; (2) simple priming cannot account for these results; and (3) verification tasks can inform studies of situated comprehension.

The Pasteurization of Marie Curie: A (meta)biographical experiment.

PubMed

Wirtén, Eva Hemmungs

2015-08-01

Biographies of scientists occupy a liminal space, highly popular with general readers but questioned in academia. Nonetheless, in recent years, historians of science have not only embraced the genre with more enthusiasm and less guilt, they have also turned to the metabiography in order to renew the study and story of scientists' roles. This essay focuses on Marie Curie, the world's most famous female scientist, in order to unpack some of the theoretical and methodological claims of the science biography, and especially to address the sexing mechanisms at play in the construction of the biographical subject. Pierre Curie (1923), Marie's biography of her husband Pierre, paid tribute to her dead husband and collaborator, but also allowed Curie a legitimate outlet to construct her own persona and legacy. Categories such as personhood, person, and persona are not only central to the biography genre but also are essential to the sense of self and self-fashioning of scientists. Looking at how Marie Curie negotiated these categories in Pierre Curie not only gives new insight into Curie's self-fashioning strategies but may also shed some light on the more general analytical lacunae of the science biography.

Learning to associate novel words with motor actions: language-induced motor activity following short training.

2012-07-01

Action words referring to face, arm or leg actions activate areas along the motor strip that also control the planning and execution of the actions specified by the words. This electroencephalogram (EEG) study aimed to test the learning profile of this language-induced motor activity. Participants were trained to associate novel verbal stimuli to videos of object-oriented hand and arm movements or animated visual images on two consecutive days. Each training session was preceded and followed by a test-session with isolated videos and verbal stimuli. We measured motor-related brain activity (reflected by a desynchronization in the μ frequency bands; 8-12 Hz range) localized at centro-parietal and fronto-central electrodes. We compared activity from viewing the videos to activity resulting from processing the language stimuli only. At centro-parietal electrodes, stable action-related μ suppression was observed during viewing of videos in each test-session of the two days. For processing of verbal stimuli associated with motor actions, a similar pattern of activity was evident only in the second test-session of Day 1. Over the fronto-central regions, μ suppression was observed in the second test-session of Day 2 for the videos and in the second test-session of Day 1 for the verbal stimuli. Whereas the centro-parietal μ suppression can be attributed to motor events actually experienced during training, the fronto-central μ suppression seems to serve as a convergence zone that mediates underspecified motor information. Consequently, sensory-motor reactivations through which concepts are comprehended seem to differ in neural dynamics from those implicated in their acquisition. Copyright © 2011 Elsevier Srl.

A previous study by the U.S. Geological Survey of impaired water bodies in Fort Worth, Texas, reported elevated but variable concentrations of particle-associated contaminants (PACs) comprising chlorinated hydrocarbons, polycyclic aromatic hydrocarbons, and trace elements in suspended and bed sediment of lakes and streams affected by urban land use. The U.S. Geological Survey, in cooperation with the City of Fort Worth, collected additional samples during October 2004 to investigate sources of PACs in the watersheds of two impaired lakes: Lake Como and Fosdic Lake. Source materials and aquatic sediment were sampled and analyzed for PACs. Source materials sampled consisted of street dust and soil from areas with residential and commercial land use and parking lot dust from sealed and unsealed parking lots. Aquatic sediment sampled consisted of bottom-sediment cores from the two lakes and suspended and streambed sediment from the influent stream of each lake. Samples were analyzed for chlorinated hydrocarbons (organochlorine pesticides and polychlorinated biphenyls), polycyclic aromatic hydrocarbons, major and trace elements, organic carbon, grain size, and radionuclides.

Debido a una distorsión en la imagen corporal, las personas que padecen Dismorfia Muscular se perciben menos musculosas de lo que son en realidad. Con el fin de aumentar su musculatura, algunas de estas personas hacen uso de hormonas cuya función principal es la del aumento del tamaño muscular. Por lo que el objetivo de este estudio es conocer la prevalencia del uso de hormonas en personas afectadas por Dismorfia Muscular. 562 hombres y 172 mujeres fisicoculturistas y levantadores de pesas, a los que se le administraron diferentes cuestionarios para conocer, primero si padecían el trastorno, y después en qué porcentaje usaban hormonas la muestra afectada. Para la creación de los modelos de regresión de la dismorfia muscular fueron empleadas las técnicas estadísticas de árboles de decisión (R = 0.78 y R2 = 0.62). Los resultados indican que casi un 50% de participantes, afectados por este trastorno, hacen uso de estas drogas. Due to a distortion in the body image, the people who suffer from muscle dysmorphia have the self-perception of being less muscular than they currently are. With the aim of increasing their muscular development, they resort to the use of AAS. The purpose of the present study is to know the prevalence of the use of AAS in a Spanish sample affected by muscle dysmorphia. 562 male and 172 female bodybuilders and weightlifters were provided with different questionnaires in order to know, firstly, if they suffered from this disorder and, secondly, the percentage of the participants affected who use these substances. Decision trees and regression was applied to create explanatory models for muscle dysmorphia (R = 0.78 and R2 = 0.62). The results show that almost 50% of the participants, male and female, affected by this disorder use this kind of drugs.

Use of black vulture (Coragyps atratus) in complementary and alternative therapies for cancer in Colombia: A qualitative study

PubMed Central

2012-01-01

Background Although Coragyps atratus has been used as a traditional therapy for patients with cancer, the scientific literature does not contain enough information on how this therapy is used or the mechanisms that explain this therapeutic practice. Objectives To understand the methods of use and the reasons given by patients and caregivers for the use of Coragyps atratus in cancer treatment. Methods This study used a qualitative design based on twenty in-depth interviews of patients with cancer or caregivers of patients with the disease. The analysis of the text was based on an inductive thematic approach. Results Resistance to disease and immune enhancement are properties attributed to Coragyps atratus when used for cancer treatment. The most recommended method of use is fresh blood ingestion, and the associated mechanism of action is transfer of immune factors to the individual who consumes it. Conclusions Use of Coragyps atratus as a treatment for cancer is a popular alternative therapy in Colombia. More studies are needed to understand the clinical effects of this intervention in cancer patients. Spanish abstract Introducción Aunque Coragyps atratus se usa tradicionalmente como terapia para pacientes con cáncer, no existe suficiente información en la literatura científica sobre su forma de utilización ni sobre los mecanismos explicativos que subyacen a esta práctica terapéutica.

To determine the prevalence of depression in Mexican adult diabetics and to identify factors associated to the depression. Prolective survey. Four Mexico City hospitals (Clinica San Pedro de los Pinos IMSS, Centro Medico Nacional Siglo XXI IMSS, Hospital Gea González SSa and Centro de Salud Margarita Chorne SSa). 79 patients with diabetes mellitus type 2. The Beck Depression Inventory was used as a measure of depression. We used sociodemographic variables (age, gender, marital status, religion, education, occupation, socioeconomic status) and disease variables (years of diagnosis, other chronic medical conditions and compliance with therapeutic regimens) as the independent variables of depression. Mean age was 59 +/- 11 years (SD) and 58 (73%) were females. The frequency of depression was 46%. Factors associated to depression were: females (OR = 3.67, CI = 1.07-13.3, p = 0.03) and years of diagnosis above 15 (OR = 3.08, CI = 0.91-10.8, p = 0.07). Frequency of depression was high (46%). Gender and years of diabetes diagnosis were factors associated to depression.

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

2011-12-01

Responding to public health emergencies requires rapid and accurate assessment of workforce availability under adverse and changing circumstances. However, public health information systems to support resource management during both routine and emergency operations are currently lacking. We applied scenario-based design as an approach to engage public health practitioners in the creation and validation of an information design to support routine and emergency public health activities. Using semi-structured interviews we identified the information needs and activities of senior public health managers of a large municipal health department during routine and emergency operations. Interview analysis identified 25 information needs for public health operations management. The identified information needs were used in conjunction with scenario-based design to create 25 scenarios of use and a public health manager persona. Scenarios of use and persona were validated and modified based on follow-up surveys with study participants. Scenarios were used to test and gain feedback on a pilot information system. The method of scenario-based design was applied to represent the resource management needs of senior-level public health managers under routine and disaster settings. Scenario-based design can be a useful tool for engaging public health practitioners in the design process and to validate an information system design. Copyright © 2011 Elsevier Inc.

to analyse the effects of relaxation as a nursing intervention on the depression levels of hospitalised women with high-risk pregnancies. a randomised clinical trial realised in a reference centre for high-risk pregnancies. The sample consisted of 50 women with high-risk pregnancies (25 in the control group and 25 in the intervention group). The Benson relaxation technique was applied to the intervention group for five days. Control variables were collected using a predesigned form, and the signs and symptoms of depression were evaluated using the Edinburgh Postnatal Depression Scale (EPDS). The Statistical Package for Social Sciences (SPSS), version 20.0, was used with a significance level of 5%. The Wilcoxon and paired t-tests were used to evaluate depression levels between two timepoints. Using categorical data, the McNemar test was used to analyse differences in depression severity before and after the intervention. depression levels decreased in the intervention group five days after the relaxation technique was applied (4.5 ± 3, p<0.05) compared with the levels at the first timepoint (10.3±5.9). as a nursing intervention, relaxation was effective in decreasing the symptoms of depression in hospitalised women with high-risk pregnancies. analisar os efeitos do relaxamento como uma intervenção de enfermagem sobre os níveis de depressão de mulheres internadas com gravidez de alto risco. ensaio clínico randomizado realizado em um centro de referência para gravidez de alto risco A amostra foi composta de 50 mulheres com gravidez de alto risco (25 no grupo controle e 25 no grupo intervenção).

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

2012-01-01

exilio: el uso de productos vegetales, animales y minerales con fines de perfumería, cosmética y curativos de la piel entre los refugiados saharauis del Sáhara Occidental. Antecedentes Durante la última década ha habido un creciente interés en los estudios etnobiológicos de los conocimientos y prácticas de las personas que migran. Dentro de esta tendencia, los estudiosos han prestado relativamente menor atención a las personas desplazadas y a los refugiados: a la pérdida, el mantenimiento y la adaptación de sus conocimientos etnobiológicos, y su importancia para el bienestar de los refugiados. Este estudio se centra en los cosméticos y remedios para curar problemas de la piel tradicionalmente utilizados por los refugiados saharauis en los campamentos de desplazados al sudoeste de Argelia. Métodos Los métodos de investigación 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 colección de muestra de las plantas y productos citados. Resultados Se registró el uso de 55 especies vegetales, nueve especies animales, y seis productos minerales utilizados en tres principales categorías de usos: 1) Recursos contra los problemas de salud característicos del entorno desértico donde una vez vivieron los saharauis como nómadas 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 nómadas saharauis; y 3) Cosméticos y productos utilizados para el cuidado del cuerpo, decoración y perfumes (por ejemplo, atención 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 prácticas sociales cotidianas de los refugiados. Conclusiones En la discusión, se analizan los cambios que se han producido en los patrones

Estudio epidemiológico de sucesos traumáticos, trastorno de estrés post-traumático y otros trastornos psiquiátricos en una muestra representativa de Chile

Pérez Benítez, Carlos I.; Vicente, Benjamin; Zlotnick, Caron; Kohn, Robert; Johnson, Jennifer; Valdivia, Sandra; Rioseco, Pedro

2010-01-01

RESUMEN Durante la década de 1990 en los Estados Unidos (EU), el conocimiento sobre el trastorno de estrés post-traumático (TEPT) evolucionó de estudios específicos en un principio, sobre veteranos de guerra y sobre víctimas de desastres, a estudios epidemiológicos más tarde, sin embargo, la epidemiología del TEPT en países en desarrollo ha sido un área poco estudiada hasta ahora. Los expertos en el área de trauma han propuesto que los sucesos traumáticos que ocurren en la niñez son más perjudiciales para la salud mental que aquellos que ocurren más tarde en la vida. Este trabajo revisa los resultados de un estudio epidemiológico llevado a cabo en Chile. Específicamente, se revisan los resultados sobre las tasas de prevalencia del TEPT, traumas asociados más frecuentemente con él, así como la comorbilidad de este trastorno con otros trastornos psiquiátricos a lo largo de la vida. Igualmente se analizaron las diferencias del TEPT en cada sexo, así como la exposición a traumas en una muestra representativa de chilenos. Además se comparó la prevalencia de trastornos psiquiátricos en personas que sufrieron su primer trauma durante la niñez, durante la edad adulta, o que no reportaron traumas durante su vida. En estos estudios epidemiológicos se usaron módulos del TEPT y trastorno de personalidad antisocial (TPA) de la entrevista diagnóstica siguiendo los criterios del DSM-III-R (DIS–III-R).

To determine the proportion of 14-year-old schoolchildren in the city of Havana, Cuba, with a positive tuberculin skin test, as an indicator of the prevalence of tuberculosis infection among them. Using single-stage cluster sampling, 1 936 Mantoux (tuberculin) tests were carried out with ninth-grade students (cohort born in 1985) during the 1999- 2000 school year in 20 basic high schools randomly selected in Havana. The tests were performed according to the standard technique recommended by the World Health Organization, and they were read after 72 hours. The percentage of skin tests that were positive and the average diameter of the indurations were calculated for the cohort overall and for the two genders. The means and the percentages were compared using the chi-square test, with 95% confidence intervals. The computer software used was Epi Info version 6.0. Of the tests read, 96% of them were negative (0-4 mm), 2.5% were doubtful (5-9 mm), and 1.5% were positive (>/=10 mm). The percentage of reactivity was 0.1% when a cutoff value of 15 mm was used. The mean diameter of the indurations was 0.41 mm. No statistically significant difference was found between the genders. In this study the proportion of schoolchildren with tuberculin reactivity, using an induration-diameter cutoff point of 10 mm, was very low (1.5%), and it was much lower (0.1%) when a cutoff point of 15 mm was used. The skin reactions with an induration diameter of >/=10 mm could be the expression of a natural infection if one takes into account the low frequency of bacillary tuberculosis in Cuba and that there is an inverse relationship between the time elapsed from the BCG vaccination and the intensity of the response to tuberculin. Therefore, that would mean that in this case (l)the point (.)prevalence of tuberculosis infection in this group of schoolchildren wou d be 1.5% ResumenObjetivos.

Este trabalho foi desenvolvido pelo projeto Astronomia no Recôncavo da Bahia, no Centro de Formação de Professores da Universidade Federal do Recôncavo da Bahia. Traçamos o perfil de um grupo de professores que lecionam conteúdos de Ciências Naturais no recôncavo, alunos do curso de Licenciatura em Ciências Naturais, oferecido dentro do Plano Nacional de Formação de Professores da Educação Básica. Nosso objetivo era avaliar se eles estão preparados para trabalhar conteúdos de Astronomia e identificar suas dificuldades. Os resultados serviram para orientar o professor da disciplina “Terra e Universo”, oferecida no segundo semestre de 2010. Durante a primeira aula da disciplina Terra e Universo, os alunos responderam a um questionário contendo questões abertas e fechadas, divididas em duas partes. A primeira procurando caracterizar profissionalmente os alunos enquanto professores da rede pública da região do Recôncavo Sul da Bahia e uma segunda parte procurando identificar conhecimentos básicos em Astronomia. Os resultados indicam uma predominância de professores do sexo feminino, com idade superior aos 40 anos, pardos e sem formação específica para o ensino de ciências. A maioria leciona há mais de 15 anos para turmas do 1º ao 5º ano, alguns lecionam para turmas de 6º ao 9º ano. Quase todos nunca participaram de um curso de formação continuada em Astronomia. Além disso, não estão habituados a ler revistas especializadas e nem livros com esta temática. Os que procuram ensinar temas voltados para a Astronomia têm, no livro didático, a maior fonte de informação sobre o assunto. As respostas também indicam uma deficiência em conteúdos básicos como a compreensão da esfericidade da Terra, noções de verticalidade e gravidade, incapacidade de identificar a Terra como um planeta, no Sistema Solar, em uma galáxia, no Universo. Estes resultados ressaltam a importância de disciplinas de Astronomia básica na formação dos

Com o objetivo de realizar um estudo cinemático da componente vertical de barras em galáxias, obtivemos espectros de fenda longa de alta razão S/N ao longo dos eixos maior e menor de 14 galáxias barradas vistas de face, nos telescópios de 1.52m do ESO em La Silla, Chile, e de 2.3m do Steward Observatory em Kitt Peak, Arizona. Estes dados nos permitiram determinar a distribuição de velocidades das estrelas ao longo do eixo vertical das barras e discos destes sistemas, tanto no centro como em pontos que distam cerca de 5 e 20 segundos de arco do núcleo, correspondendo a distâncias de cerca de 0.7 e 2.8 kpc, respectivamente. Desta forma, a variação radial da distribuição de velocidades também pôde ser avaliada. Este tipo de análise tem raros exemplos na literatura por ser caro em termos de tempo de telescópio. Entretanto, é de fácil justificativa, considerando que traz novas informações que podem ser utilizadas para aperfeiçoar modelos teóricos acerca da formação e evolução de galáxias. Um algoritmo por nós desenvolvido foi utilizado para obter as distribuições de velocidades como Gaussianas generalizadas (polinômios de Gauss-Hermite), o que traz um ingrediente a mais neste tipo de estudo que, tradicionalmente, se utiliza de Gaussianas puras, uma hipótese nem sempre razoável. Apresentaremos os resultados deste trabalho, que incluem um diagnóstico para a identificação de barras recém formadas, e testes para o modelo isotérmico de discos. Mostraremos que: (i) a escolha das estrelas padrão em velocidade, e dos parâmetros da Gaussiana, deve ser muito bem justificada já que tem influência significativa nos resultados; (ii) muitas galáxias apresentam uma depressão na dispersão de velocidades na região central, que pode estar associada a um disco interno; e (iii) a dispersão de velocidades é constante ao longo da barra, nos eixos maior e menor, mas cai substancialmente quando se passa da barra para o disco.

Resumen Antecedentes La presencia de metástasis en los ganglios linfáticos (MGL) en la prostatectomía radical de rescate (PRs) se asocia con un mal pronóstico. Los factores predictivos de resultados en este contexto siguen siendo indeterminados. El objetivo fue evaluar el papel de número de ganglios linfáticos positivos sobre el resultado de los pacientes con MGL después de PRs y para el cáncer de próstata de radio-recurrente. Material y métodos Se analizaron los datos de una cohorte consecutiva de 215 hombres tratados con PRr en una sola institución. Se utilizaron los modelos de regresión de riesgos proporcionales de Cox univariante para la recurrencia bioquímica (RBQ) y los resultados metastásicos, con el antígeno prostático específico, la puntuación de Gleason, la extensión extraprostática, la invasión de vesículas seminales, el tiempo entre la terapia de radiación y PRr y el número de ganglios positivos como factores predictivos. Resultados De los 47 pacientes con MGL, 37 desarrollaron RBQ, 11 desarrollaron metástasis a distancia y 4 fallecieron con una mediana de seguimiento de 2,3 años para los supervivientes. El riesgo de metástasis aumentó con mayores niveles preoperatorios de PSA (HR 1,19 por 1 ng/ml; IC del 95%: 1,06, 1,34; p = 0,003). Los factores predictivos restantes no alcanzaron niveles convencionales de significación. Sin embargo, la eliminación de 3 o más ganglios linfáticos positivos demostró una asociación positiva, como se esperaba, con enfermedad metastásica (HR 3,44, IC: 0,91, 13,05; p = 0,069) en comparación con uno o dos ganglios positivos. Del mismo modo, la presencia de extensión extraprostática, invasión de vesículas seminales y grado de Gleason superior a 7 también demostraron una asociación positiva con un mayor riesgo de metástasis, con índices de riesgo de 3,97 (IC del 95% 0,50; 31,4; p = 0,2), 3,72 (IC 95% 0,80, 17,26; p = 0,1) y 1,45 (IC del 95% 0,44, 4,76; p = 0,5), respectivamente

An abbreviated primer on the sociology of the family is presented. The work defines family, describes different types of family structure, outlines the family life cycle, and discusses the functioning of families. Human beings in all societies require membership in a family of some type for reproduction and socialization. One of the most basic human needs is for a mother who will feed, protect, and instruct her offspring. Families have always changed in response to societal changes. The functions of a family are devoted to two different sets of objectives, the internal ones of psychosocial protection of the members and the external ones of accommodation to and transmission of a culture. Families in all cultures provide their members with a sense of identity. Families must respond to internal and external changes and should be capable of transforming themselves to adjust to new circumstances without losing continuity. Family systems differentiate themselves to carry out their functions through their subsystems. Individuals and dyads such as maternal-child or husband-wife are the subsystems. The family life cycle entails a series of stages: courtship, marriage, the birth and growth of children, separation of the children, retirement, old age. Each stage has its own pitfalls and challenges. Each family has a hierarchy of status and power, although in some cases the proper hierarchies are inverted, and the children carry out functions that should be completed by the parents. A series of explicit and implicit, rigid and flexible rules guide the functioning of the family. Various roles are carried out, including parental, marital, and sibling roles, as well as roles of authority, administration, and messenger.

The IBA conference has taken place in different countries from all over the world. It started in the United States in 1973, and since then has been held biennially without interruption, becoming the reference meeting on ion beam analysis and related methods and techniques. In its 17th edition, two Spanish laboratories, one from the Universidad de Sevilla and one from the Universidad Autónoma de Madrid had the honour and responsibility of organizing the conference. These two laboratories are, so far, the only ones in the country equipped with accelerators dedicated to ion beam analysis; the Centro Nacional de Aceleradores (CNA) in Seville and the Centro de Micro-Análisis de Materiales (CMAM) in Madrid. We took up this task enthusiastically, conscious that Spain has only very recently been equipped with IBA techniques and that this event would highlight to the scientific community of our country the importance and involvement of IBA techniques in new scientific and technological developments. The conference was held at the Melia Sevilla Hotel in Seville, Spain from 26 June-1 July 2005. This special issue of Nuclear Instruments and Methods in Physics Research B contains the published proceedings of the conference.

To evaluate the association between calf circumference and gait speed in elderly patients 65 years or older at Geriatric day clinic at Peruvian Centro Médico Naval. Cross-sectional, retrospective study. We assessed 139 participants, 65 years or older at Peruvian Centro Médico Naval including calf circumference, gait speed and Short Physical Performance Battery. With bivariate analyses and logistic regression model we search for association between variables. The age mean was 79.37 years old (SD: 8.71). 59.71% were male, the 30.97% had a slow walking speed and the mean calf circumference was 33.42cm (SD: 5.61). After a bivariate analysis, we found a calf circumference mean of 30.35cm (SD: 3.74) in the slow speed group and, in normal gait group, a mean of 33.51cm (SD: 3.26) with significantly differences. We used logistic regression to analyze association with slow gait speed, founding statistically significant results adjusting model by disability and age. Low calf circumference is associated with slow speed walk in population over 65 years old. Copyright © 2014. Published by Elsevier Espana.

Spin re-orientation in heavy fermion system α - YbAl1 - x FexB4

Wu, Shan; Broholm, C.; Kuga, K.; Suzuki, Shintaro; Nakatsuji, S.; Mourigal, M.; Stone, M.; Tian, Wei; Qiu, Y.; Rodriguez-Rivera, Jose

Non centro-symmetric α - YbAlB4 has a heavy Fermi liquid ground state and shares many characteristics with centro-symmetric β - YbAlB4 . Both isomorphs display intermediate valence, associated with a fluctuation scale of T0 = 200 K and a Kondo lattice scale of T* = 8 K. Unlike β - YbAlB4 , α - YbAlB4 is at the boundary of a transition from a Fermi liquid metallic state to an antiferromagnetic (AFM) insulating state, driven by Fe substitution of Al. Magnetization and specific heat measurements reveal two different antiferromagnetic phases with TN = 9 K and TN = 2 K for Fe concentration above and below x =0.07. We report single crystal neutron scattering experiments on Fe doped YbAlB4 with x =0.035 and x =0.125. While the ordering wave vector is identical, k -> = (1 , 0 , 0) , the spin orientation switches from c to a with increasing Fe concentration. This suggests different anisotropic hybridization between 4f and conduction electrons that we confirmed by determining the crystal field levels. Supported by DOE, BES through DE-FG02-08ER46544.

On the Role of Mentalizing Processes in Aesthetic Appreciation: An ERP Study.

PubMed

Beudt, Susan; Jacobsen, Thomas

2015-01-01

We used event-related brain potentials to explore the impact of mental perspective taking on processes of aesthetic appreciation of visual art. Participants (non-experts) were first presented with information about the life and attitudes of a fictitious artist. Subsequently, they were cued trial-wise to make an aesthetic judgment regarding an image depicting a piece of abstract art either from their own perspective or from the imagined perspective of the fictitious artist [i.e., theory of mind (ToM) condition]. Positive self-referential judgments were made more quickly and negative self-referential judgments were made more slowly than the corresponding judgments from the imagined perspective. Event-related potential analyses revealed significant differences between the two tasks both within the preparation period (i.e., during the cue-stimulus interval) and within the stimulus presentation period. For the ToM condition we observed a relative centro-parietal negativity during the preparation period (700-330 ms preceding picture onset) and a relative centro-parietal positivity during the stimulus presentation period (700-1100 ms after stimulus onset). These findings suggest that different subprocesses are involved in aesthetic appreciation and judgment of visual abstract art from one's own vs. from another person's perspective.

Ambiguity Resolution for Phase-Based 3-D Source Localization under Fixed Uniform Circular Array.

Chen, Xin; Liu, Zhen; Wei, Xizhang

2017-05-11

Under fixed uniform circular array (UCA), 3-D parameter estimation of a source whose half-wavelength is smaller than the array aperture would suffer from a serious phase ambiguity problem, which also appears in a recently proposed phase-based algorithm. In this paper, by using the centro-symmetry of UCA with an even number of sensors, the source's angles and range can be decoupled and a novel algorithm named subarray grouping and ambiguity searching (SGAS) is addressed to resolve angle ambiguity. In the SGAS algorithm, each subarray formed by two couples of centro-symmetry sensors can obtain a batch of results under different ambiguities, and by searching the nearest value among subarrays, which is always corresponding to correct ambiguity, rough angle estimation with no ambiguity is realized. Then, the unambiguous angles are employed to resolve phase ambiguity in a phase-based 3-D parameter estimation algorithm, and the source's range, as well as more precise angles, can be achieved. Moreover, to improve the practical performance of SGAS, the optimal structure of subarrays and subarray selection criteria are further investigated. Simulation results demonstrate the satisfying performance of the proposed method in 3-D source localization.

2016-01-01

The experience of chronic pain is universal, yet pain management services delivered by health professionals vary substantially, depending on the context and patient. This review is a part of a series that has examined the issue of chronic non-cancer pain services and management in different global cities. The review is structured as a case study of the availability of management services for people living with chronic non-cancer pain within the context of the Kuwaiti health systems, and the cases are built from evidence in the published literature identified through a comprehensive review process. The evolution of the organizational structure of the public and private health systems in Kuwait is described. These are discussed in terms of their impact on the delivery of comprehensive chronic pain management service by health professionals in Kuwait. This review also includes a description of chronic pain patient personas to highlight expected barriers as well as compliance issues with services likely to be encountered in Kuwait. The case study analysis and persona descriptions illustrate a need to move beyond pain symptom management towards considering the entire person and his/her individual experience of pain such that health care success is judged by enhancement of patient well-being rather than access to services. A road map for improving integrative chronic pain management in Kuwait is discussed. PMID:26595816

To demonstrate how a human-centered service design approach can generate practical tools for good-quality childbirth care in low-resource settings. As part of the WHO "Better Outcomes in Labour Difficulty" (BOLD) project, a service design approach was used in eight Ugandan and Nigerian health facilities and communities to develop the "Passport to Safer Birth." There are three phases: Research for Design, Concept Design, and Detail Design. These generated design principles, design archetype personas, and Passport prototypes. Data collection methods included desk research, interviews, group discussions, and journey mapping to identify touchpoints where the woman interacts with the health system. A total of 90 interviews, 12 observation hours, and 15 group discussions were undertaken. The resulting design principles were: a shared and deeper understanding of pregnancy and childbirth among family and community; family readiness for decision-making and action; and the woman's sense of being in control and being cared for. Four archetype personas of women emerged: Vulnerable; Passive; Empowered; Accepter. Subsequent development of the Passport to Safer Birth tools addressed three domains: Care Mediator; Expectation Manager; and Pregnancy Assistant. The service design approach can create innovative, human-centered service solutions to improve maternity care experiences and outcomes in low-resource settings. © 2017 International Federation of Gynecology and Obstetrics The World Health Organization retains copyright and all other rights in the manuscript of this article as submitted for publication.

Introducción: en la actualidad existe un déficit en la evaluación de comedores dirigidos a niños menores de 3 años, a pesar de que se han realizado numerosas intervenciones en los comedores escolares con el fin de conseguir una alimentación segura y adecuada.Objetivo: realizar una evaluación nutricional de los menús ofertados en los centros de educación infantil de Sevilla.Material y métodos: se evaluó la frecuencia, variedad, rotación de alimentos, métodos culinarios e información de los menús de seis centros infantiles de Sevilla. Se valoró el aporte energético y nutricional mediante el programa Dietowin® y el método de pesada.Resultados: las frutas y verduras fueron deficitarias en la mayoría de los menús, y excesivas la carne, patatas, pasta y arroz. Se observó una escasa variedad de recetas por grupo de alimentos y no se daba una información completa del menú. Sin embargo, la variedad de procesos culinarios y la rotación de alimentos fueron adecuadas. Aunque la energía y el aporte de carbohidratos (~55%) se ajustaban a las necesidades, se observó un aporte excesivo de proteínas (~19%) y deficiente de lípidos (< 30%), sobre todo de grasas insaturadas. Respecto a los micronutrientes,solo vitamina C, E y calcio estaban por debajo de lo recomendado.Conclusiones: los centros de educación infantil están haciendo un gran esfuerzo por cumplir las recomendaciones nutricionales, pero todavía deben disminuir el aporte proteico y aumentar las grasas insaturadas de la dieta. Además, deben fomentar la oferta de frutas y verduras, ampliar la variedad de recetas, dar mayor información y disminuir el aporte de alimentos cárnicos.

Introducción: a finales del siglo xx, no se conocía con precisión si la comida del comedor escolar contribuía adecuadamente a la dieta de la población infantil. Además, este servicio complementario no se contemplaba en el proyecto educativo del centro pese a considerarse fundamental en todas sus dimensiones.Objetivo: describir el origen y desarrollo del programa de comedores escolares de la Comunidad de Madrid (CM) en 15 años desde su implantación.Métodos: se elaboró una normativa a cumplir por las empresas de restauración, y que contemplaba aspectos nutricionales y de composición y variedad de los menús, que se utilizó en los concursos para acceder a la prestación del servicio de comedor escolar, publicados en los años 2001, 2002, 2005, 2009 y 2013. Además se realizaron visitas acreditadas a los centros sin previo aviso para verifi car el cumplimiento de la documentación aportada durante el concurso.Resultados: los criterios más actuales sobre programación y elaboración de menús escolares se recogen en el Pliego de Prescripciones Técnicas del año 2013 (C-504/001-2013). Un 92% de las empresas de restauración superaron los cinco concursos habidos en los 15 años de funcionamiento. Hasta el año 2014, se han realizado 755 visitas, revisándose un total de 574 centros.Conclusiones: el programa de comedores escolares de la CM, desde su implementación pionera en España, ha contribuido a la mejora del servicio complementario de comedor. En estos años se han ido incluyendo nuevos requisitos dietéticos y nutricionales que han logrado menús cada vez más ajustados a las recomendaciones de la población escolar.

Las respuestas escritas más comunes a nuestra encuesta indicaran que los estudiantes necesitan más orientación y una mejor preparación en la redacción de ensayos exitosos. Dado que los estudiantes encontraron las piezas conceptuales de los ensayos difíciles, en el futuro vamos a ofrecer actividades pertinentes antes de los plazos de redacción para ayudar a los estudiantes a crear ensayos de mayor calidad. Nós ocasionalmente incluímos projetos em nosso curso universitário introdutório centrado no aluno para permitir aos estudantes que pertencem às carreiras não científicas explorar alguns conceitos astronômicos em mais detalhes do que o normal. Tais projetos também enfatizam eventos astronômicos em curso ou futuros. Esperamos que os alunos se sintam mais interessados na astronomia através de projetos ligados a eventos astronômicos.

Objetivo: analizar la geografía del estado nutricional en España y su evolución entre mediados del siglo xixy comienzos del siglo xx, etapa previa a la transición nutricional con alta prevalencia de malnutrición.Métodos: se utilizan datos antropométricos agregados (promedios provinciales de estatura) del reclutamiento militar en 1858 y 1913, así como promedios provinciales de estatura y peso procedentes de una revisión realizada entre 119.571 soldados en 1903-1906. Con estos datos se elaboran cartografía y estadísticos descriptivos.Resultados: los parámetros antropométricos de los españoles se situaban entre los valores de complexión más bajos de Europa antes de la transición nutricional. Entre 1858 y 1913, la altura media creció solo 1,43 cm. En ese periodo hubo cambios significativos en la geografía antropométrica marcados por la configuración de una polaridad nutricional a las puertas de la I Guerra Mundial: las provincias del centro y del sur de país exhiben mayor incidencia de la malnutrición crónica que las provincias del arco Noreste, que disfrutan de ventaja relativa en términos nutricionales.Conclusión:las desigualdades territoriales que configuraron una geografía polarizada del estado nutricional en España pueden asociarse en parte a los cambios ambientales del periodo, caracterizados por el inicio de la modernización y la industrialización y, asimismo, por la privación derivada de las crisis agrarias, las enfermedades y el relativo atraso tecnológico. Se destaca la relevancia de la historia antropométrica para el estudio de los niveles de vida en poblaciones del pasado y del proceso de transición nutricional.
