PubMed

RESUMEN Fundamento: En 2008, se puso en marcha el programa Ni ogros ni princesas en 12 centros de secundaria de Asturias (España) para incorporar la educación afectivo-sexual. El programa proponía 14 actividades, dirigidas a alumnado, profesorado y familias. Este estudio recoge la evaluación de proceso de esta intervención, en relación a la ejecución de las actividades, participación, satisfacción, utilidad percibida y propuestas de mejora. Métodos: La población de estudio fueron los 12 centros que participaron en el programa, y su alumnado, profesorado y familias. Se obtuvo información sobre la ejecución de actividades mediante un cuestionario de seguimiento; se recogió la satisfacción y utilidad percibida con cuestionarios auto-administrados para alumnado y profesorado; también se recogieron sus propuestas de mejora, y las de las familias, en grupos focales. Resultados: El número medio de actividades realizadas por los 12 centros fue 11,6. Se implicaron 185 docentes (26%), que impartieron sesiones al 81% del alumnado en estos 12 centros. El número medio de sesiones impartidas fue 6 en cada nivel de la ESO. El 79% del profesorado se sintió bastante/muy satisfecho con su actuación y al 65% del alumnado le gustaron bastante/mucho estas sesiones. Más del 60% de estudiantes y docentes consideraron que estas sesiones servían bastante/mucho para aumentar conocimientos, reflexionar, mejorar la igualdad, conocer otras opiniones y favorecer el respeto a la diversidad sexual. Entre las propuestas de mejora, más horas para la educación sexual, liberación horaria para el profesorado, y más actividades para familias. Conclusiones: El programa fue una intervención novedosa y percibida como útil para incorporar la educación sexual en los centros de secundaria, ya que contó con un gran nivel de ejecución, así como una alta participación, satisfacción y utilidad percibida por el alumnado y profesorado.

[Programa de saúde: a case of book censorship during the Brazilian military dictatorship].  

PubMed

Some documents produced by the government during the Brazilian military dictatorship have been made available for reference, including censors' reports on television and radio programs, plays, films, songs, advertisements and printed matter. Of the 500 or so reports on books, there is one that vetoes Programa de saúde: projetos e temas de higiene e saúde, an educational work that proposed actions to help students understand their sanitary conditions and acquire knowledge about health and health-promoting habits in this area. The argument for vetoing it was that the information could fall into the hands of poorly trained teachers, who could distort its content, causing serious damage to Brazilian youth. In this report we see evidence of the obscurantist, elitist posture adopted by the Department of Censorship of Public Entertainment, which aimed to restrict the circulation of information and curb debate.

BUDDA (Bulge/Disk Decomposition Analysis) - um novo programa para análise estrutural de galáxias  

NASA Astrophysics Data System (ADS)

Tem sido prática comum nos últimos anos estudar a distribuição de luminosidade em galáxias fazendo uso da informação contida em toda a imagem da galáxia, já que esta técnica tem se mostrado muito mais confiável do que o simples ajuste de perfis radiais de luminosidade. Através destes estudos bidimensionais, melhores resultados tem sido obtidos na análise e.g. do Plano Fundamental, de correlações entre os parâmetros estruturais de galáxias, de sub-estruturas como barras e anéis nucleares etc. Apresentamos um novo código bidimensional, o BUDDA, de análise estrutural de galáxias, que será disponibilizado para a comunidade. Desenvolvido por nós, o código determina os parâmetros estruturais de galáxias de forma prática e robusta, e pode ser aplicado genericamente em qualquer estudo sobre a formação, evolução e estrutura de galáxias. O programa ainda permite a avaliação direta de sub-estruturas, através de imagens residuais que são obtidas ao se subtrair, das imagens originais, bojo e disco sintéticos que melhor representam essas componentes da galáxia sob consideração. Será apresentada a forma de utilização do código, bem como séries de testes que atestam a sua funcionalidade. Além disso, os resultados da aplicação do código em uma amostra de 51 galáxias serão expostos como exemplo prático, e do seu enorme potencial de uso.

Designing a behavioral program for a barrio in Tegucigalpa, Honduras  

PubMed Central

Health in Housing initiated a behavioral program of education and skills training for children and adults in a community of 30,000 persons living in substandard conditions in Tegucigalpa, Honduras. To measure achievement in the long-range project, 21 families of Flor del Campo participated in a preliminary three-part survey of their (a) health, (b) housing and the environment, and (c) family history. Doctors, designers, and educators worked with Honduran personnel in the first survey. Following functional analyses of the home and surrounding environment and the physical status of the individuals living there, procedures provide the family with treatment and training for home and environment improvement. Graphic, verbal, and numerical data, incorporated into a master computerized system, record events of each family member: training programs experienced, health care delivery courses taken, medical treatments, growth of children, literacy changes, educational courses completed, kinds and amounts of foods eaten, household and building materials purchased. Ongoing functional analysis and a long-range evaluation are made of the progress of each participating individual in a family. Teams revisit each house to observe and record any changes in the physical and environmental facility and the health and life-styles, and to report any indications of new health problems or recurrences.

An assessment of Spain's Programa AGUA and its implications for sustainable water management in the province of Almería, southeast Spain.  

PubMed

Spain's Programa AGUA was proposed in 2004 as a replacement for the Spanish National Hydrological Plan and represented a fundamental policy shift in national water management from large inter-basin water transfers to a commitment to desalination. Twenty-one desalination facilities are planned for six provinces on the Spanish Mediterranean coast to supplement their water needs. These include the province of Almería that for the last 30 years has endured a net water abstraction overdraft leading to serious reservoir depletion and groundwater imbalances. Rising water use is a result of increasing demand to support irrigated agriculture (e.g. greenhouse horticulture) and for domestic needs (e.g. rapid urban growth and tourism development), which has led observers to question Almería's long-term water sustainability. Desalinated water alone is unlikely to be sufficient to make up these water deficits and water-users will have to accept a move to full-price water recovery by 2010 under the European Union (EU) Water Framework Directive of which Spain is a signatory. Anticipated water efficiencies resulting from higher water tariffs, increasing water reuse and water infrastructure improvements (including inter-basin transfers), in conjunction with increasing use of desalinated water, are expected to address the province's current water overdraft. However, Almería will need to balance its planned initiatives against long-term estimates of projected agricultural and domestic development and the environmental consequences of adopting a desalination-supported water future.

EI programa NASOAN fue diseiiado para caracterizar las concentraciones y el transporte de sedimento y constituyentes quimicos seleccionados, encontrados en los grandes rios de los Estados Unidos - incluyendo el Misisipi, el Colorado y el Columbia, ademas del Rio Grande. En estas cuatro cuencas, el USGS opera actualmente (1998) una red de 40 puntos de muestreo pertenecientes a NASOAN, con un enfasis en cuantificar el flujo en masa (la cantidad de material que pasa por la estacion, expresado en toneladas por dial para cada constituyente. Aplicacando un enfoque consistente, basado en la cuantificacion de flujos en la cuenca del Rio Grande, el programa NASOAN esta generando la informacion necesaria para identificar fuentes regionales de diversos contaminantes, incluyendo sustancias qui micas agricolas y trazas elementos en la cuenca. EI efecto de las grandes reservas en el Rio Grande se puede observar segun los flujos de constituyentes discurren a 10 largo del rio. EI analisis de los flujos de constituyentes a escala de la cuenca proveera los medios para evaluar la influencia de la actividad humana sobre las condiciones de calidad del agua del Rio Grande.

The Chola life course: Chicana heroin users and the barrio Gang.  

PubMed

The theoretical argument of the paper is as follows: Traditional values may deter many Latinas from drug use, but they operate to ostracize adolescent girls from cholo (street) families. Those girls may be propelled into drug-using youth gangs or similar peer groups, where they are further channeled to the more deviant subcliques. This pivotal experience initiates a drug-oriented adult lifestyle. Gender norms mean that the typical male career path to and from the gang is different. Data bearing on this argument are presented, and research and intervention implications are explored. PMID:7960308

Improving health equity through theory-informed evaluations: a look at housing first strategies, cross-sectoral health programs, and prostitution policy.  

PubMed

The emergent realist perspective on evaluation is instructive in the quest to use theory-informed evaluations to reduce health inequities. This perspective suggests that in addition to knowing whether a program works, it is imperative to know 'what works for whom in what circumstances and in what respects, and how?' (Pawson & Tilley, 1997). This addresses the important issue of heterogeneity of effect, in other words, that programs have different effects for different people, potentially even exacerbating inequities and worsening the situation of marginalized groups. But in addition, the realist perspective implies that a program may not only have a greater or lesser effect, but even for the same effect, it may work by way of a different mechanism, about which we must theorize, for different groups. For this reason, theory, and theory-based evaluations are critical to health equity. We present here three examples of evaluations with a focus on program theories and their links to inequalities. All three examples illustrate the importance of theory-based evaluations in reducing health inequities. We offer these examples from a wide variety of settings to illustrate that the problem of which we write is not an exception to usual practice. The 'Housing First' model of supportive housing for people with severe mental illness is based on a theory of the role of housing in living with mental illness that has a number of elements that directly contradict the theory underlying the dominant model. Multisectoral action theories form the basis for the second example on Venezuela's revolutionary national Barrio Adentro health improvement program. Finally, decriminalization of prostitution and related health and safety policies in New Zealand illustrate how evaluations can play an important role in both refining the theory and contributing to improved policy interventions to address inequalities. The theoretically driven and transformative nature of these interventions create special demands for the use of theory in evaluations. PMID:22652205

Morphologically distinct circumoval precipitin reactions, not having the usual "segmented" appearance, are characteristic of recently acquired infection of man with Schistosoma japonicum. In contrast to the precipitins seen in plasma of those with chronic infections, reactions of recent infection (RRI) are commonly, large, vacuolated blebs or, if elongate, are smooth and vacuolated in structure. Recognition of these RRI provides a practical, simple method to study incidence of infection and the techniques used are readily accepted by children in primary school grades. PMID:7189969

The IHS dental program--a historical perspective.  

PubMed

The federal government provides health services for American Indians and Alaska Natives based on treaties with tribes, legislation, and executive orders. These services began in the late 1700s, when they were the responsibility of the Department of War. This responsibility was later transferred to the Bureau of Indian Affairs and in 1955 the Indian Health Service was established within the United States Public Health Service. This paper describes the development and mission of the Indian Health Service dental program. During the 1950s, Public Health Service officers were assigned to the dental program, dental assistant training centers were established, and clinical prevention programs were implemented. Increased dentist recruitment, the implementation of four-handed dentistry, and the development of an automated information system were the highlights of the 1960s. Considerable effort was placed on work force development during the 1970s, while expansions of both treatment and prevention services were the highlights of the 1980s. Unfortunately, decreases in administrative staffing and a decline in clinical services have been noted during the last decade. The main reasons for the decline were initiatives to reduce the size of federal government and inability to recruit and retain dentists in clinical positions. Also, many tribes have elected to manage their own programs and have requested and received their share of IHS administrative funds to use in their programs. Recent pay and budget legislation along with changes in program management should reverse this trend. PMID:11243041

Alcohol medical scholars program--a mentorship program for improving medical education regarding substance use disorders.  

PubMed

The Alcohol Medical Scholars Program (AMSP) is designed to improve medical education related to substance use disorders (SUDs) through mentorship of junior, full-time academic faculty from medical schools across the United States. Scholarship focuses on literature review and synthesis, lecture development and delivery, increasing SUD education in their medical schools, professional development, and networking. Results are reported from an anonymous survey of self-reported changes in educational involvement by 28 of 33 AMSP graduates. Participation was associated with a 4-fold increase in yearly SUD lecture time and topics, increased numbers of medical disciplines taught and trained in clinical rotations, design of new SUD-related electives and journal clubs, and membership on medical education committees. Sixty percent of scholars reported promotion since involvement in AMSP, with the majority endorsing the organization's contribution to professional development. AMSP is a useful mentorship model for junior faculty and is associated with increasing SUD-related medical education. PMID:21660871

Profesionalismo: Un estudio fenomenologico sobre experiencias de universitarios en programas de salud  

NASA Astrophysics Data System (ADS)

Some studies suggest that, upon admission, medicine programs students display eagerness for community service, aspirations to be useful, and to contribute to society's well-being. Those same studies reflect that qualities of idealism, moral nature, and internal motivation, suffer a subsequent diminishing. The researchers inferred that the main reason for this process of change in the mood and disposition of these future physicians lies in the modeling they receive from medical professionals throughout clinical learning activities, by way of behavior and relationships exhibited during daily interaction with peers, patients and the students themselves. This phenomenological study used a cross-sectional sample to explore the experiences of future health workers as they went through didactic and clinical phases of their training curriculum. The study employed semi-structured interviews and reflective journals to explore those experiences and to discover the meanings ascribed by the participants. The analysis revealed that the students defined "professionalism" in terms of scientific knowledge, commitment, respect for human dignity, comradeship, courtesy, empathy, integrity, altruism, motivation. They also described their feelings as they went through the didactic and clinical experiences, and recognized as very important the extracurricular activities of community service, describing them as useful opportunities which contributed to understand their work in terms of a mission dedicated to the achievement of the social benefit. From their individual perspectives, the clinical environment could, in general, be described as congruent with those characteristics of professionalism. During the study we had the opportunity to share, in a little deeper way, the environment... the world... of this small group of young students as we went on trying to decipher their feelings and thoughts. At the end, we realized the richness of their sensibilities, we perceived the intensity of their moral and ethical convictions, we were able to understand their concerns, worries, struggles and efforts. This life event had profound and significant repercussions in our personal and professional life. As a result, and from now on, we will no longer look at our young scholars and apprentices without imagining a noble spirit, with goals which at times could seem unattainable... without completely visualizing or conceiving real hope for a better country.

Aportes del Aprendizaje Basado en Problemas (ABP) en la ensenanza de la Fisiologia Animal en un programa de Zootecnia  

NASA Astrophysics Data System (ADS)

Based on difficulties observed on the subject of technical-scientific conceptualization and the integration of theory and practice in learning animal physiology for students in the Animal Science program at the National University of Colombia in Medellin, this research paper proposes a problem-based learning strategy founded on the method of Problem Based Learning (PBL), applied specifically to the issues of thermoregulation and physiological stress in domestic animals. In this case study, a sample size of eight students was presented with a pedagogical problem during the first session that would then be solved during the course. In order to evaluate the process, three surveys were conducted called Level Test Formulations (NF) performed at different times of the trial: one before beginning the topic (NF 1), one after three theoretical classes had been given and before beginning the fieldwork (NF 2), and another one after the end of the process (NF 3). Finally, individual interviews were conducted with each student to know the students' perceptions regarding the method. The information obtained was subjected to a qualitative analysis and categorization, using the QDA Miner program which reviewed and coded texts from the surveys and individual interviews, supplemented in turn, by field observation, analyzing the conceptual change, the theory-practice relationship and the correlation between the variables and categories established. Among the main results obtained, it should be noted that following the implementation of PBL in this Animal Physiology course, support for conceptual change was demonstrated and the formulated problem served as a connector between theory and practice. Moreover, there was a fusion of prior knowledge with newly acquired knowledge, meaningful learning, improvement in the level of conceptualization and an increase in the scientificness of definitions; it also led to problem-solving and overcoming epistemological obstacles such as multidisciplinarity and nonlinearity. As a result of this research, it is recommended that this method be evaluated in other topics related to Animal Physiology, in other sciences, in larger sample sizes, as well as to address the issue of evaluation applied directly to this method. Key words: Problem Based Learning (PBL), conceptual change, integration of theory and practice, significatif learning, animal physiology, thermoregulation, physiological stress.

Programa de fortalecimiento de capacidades: reflections on a case study of community-based teacher education set in rural northern Peru  

NASA Astrophysics Data System (ADS)

This article explores distinctive features of a 5-year international education development project set in rural northern Peru (PROMEB, the Proyecto de Mejoramiento de la Educación Básica). Grounded within a partnership between teacher educators from Peru, Mexico and Canada, and rural Peruvian teachers, students and their communities, we offer reflections on a teacher education initiative which sought to support action-orientated inquiries as a mechanism for school/community development. Set against a background of poverty, hunger, isolation and an "educational crisis", we outline our pedagogy and describe two projects. We then reflect on the influences of our engagements and on associated tensions and ambiguities in our methods. We hope that such discussions might offer insights for others involved in international school/community development projects of this type.

Water-gas dynamics and coastal land subsidence over Chioggia Mare field, northern Adriatic Sea  

NASA Astrophysics Data System (ADS)

A major development programme comprising 15 gas fields of the northern Adriatic Sea has recently been submitted to the Ministry of the Environment, VIA Committee for the assessment of the environmental impact, by ENI-Agip, the Italian national oil company. One of the largest reservoirs is Chioggia Mare, located about 10 km offshore of the Venetian littoral, with a burial depth of 1000-1400 m. The planned gas production from this field is expected to impact the shoreline stability with a potential threat to the city of Venice, 25 km northwest of the center of Chioggia Mare. To evaluate the risk of anthropogenic land subsidence due to gas withdrawal, a numerical model was developed that predicts the compaction of both the gas-bearing formations and the lateral/bottom aquifer (water drive) during a 13-year producing and a 12-year post-production period, and the transference of the deep compaction to the ground surface. To address the uncertainty of a few important hydromechanical parameters, several scenarios are simulated and the most pessimistic predictions obtained. The modeling results show that at most 1 cm of land subsidence over 25 years may be expected at the city of Chioggia, whereas Venice is not subject to settlement. If aquifer drawdown is mediated by water injection, land subsidence is arrested 5 km offshore, with the Chioggia littoral zone experiencing a rebound of 0.6-0.7 cm. Résumé. Un important programme de développement portant sur 15 gisements de gaz du nord de l'Adriatique a été récemment soumis au Comité VIA pour l'évaluation de l'impact sur l'environnement du Ministère de l'Environnement, par la société ENI-Agip, la compagnie nationale pétrolière italienne. L'un des plus importants réservoirs est celui de Chioggia Mare, situé à environ 10 km au large du littoral vénitien, à une profondeur de 1000 à 1400 m. La production de gaz prévue pour ce gisement laisse envisager un impact sur la stabilité du trait de côte, avec une menace potentielle pour la ville de Venise, à 25 km au nord-ouest du centre de Chioggia Mare. Afin d'évaluer le risque de subsidence du sol provoquée par les prélèvements de gaz, un modèle numérique a été développé pour prévoir la compaction des formations réservoirs de gaz en même temps que celle de l'aquifère latéral et sous-jacent, par effet de drainance, sur une période de 13 ans de production, suivie de 12 ans, et pour prévoir le transfert de la compaction profonde jusqu'à la surface du sol. Afin de prendre en compte l'incertitude sur un petit nombre de paramètres hydromécaniques importants, plusieurs scénarios ont été simulés et les prévisions les plus pessimistes ont été obtenues. Les résultats de la modélisation montrent qu'on doit s'attendre, au cours des 25 ans, au plus à une subsidence du sol de 1 cm à Chioggia, tandis que Venise ne subira aucun effet. Si la baisse de l'aquifère est compensée par une injection d'eau, la subsidence du sol s'arrêtera à 5 km au large et la zone côtière de Chioggia subira un effet de 0,6 à 0,7 cm. Resumen. Recientemente, la compañía nacional italiana del petróleo, ENI-Agip, ha enviado al Ministerio de Medio Ambiente de Italia (Comité VIA) un gran programa de desarrollo de 15 campos de gas en el norte del Mar Adriático para la evaluación de su impacto medioambiental. Una de las reservas principales de gas se halla en el mar de Chioggia, a unos 10 km mar adentro de la costa veneciana, a una profundidad de entre 1.000 y 1.400 m. Se espera que la producción en este campo produzca un impacto en la estabilidad de la línea de costa, y que suponga una amenaza potencial para la ciudad de Venecia, situada a 25 km al noroeste de la explotación. Se desarrolló un modelo numérico para evaluar el riesgo de subsidencia debido a la extracción de gas a lo largo de los 13 años de producción y del período post-productivo de 12 años. Sus predicciones indican que se causará la compactación tanto de la formación que contiene el gas como del acuífero inferior y lateral. Además, esta compac

Implementation of genetic conservation practices in a muskellunge propagation and stocking program [Implementaci??n de pr??cticas gen??ticas de conservaci??n dentro de un programa de crianza y propagaci??n del lucio rayado  

USGS Publications Warehouse

Conservation of genetic resources is a challenging issue for agencies managing popular sport fishes. To address the ongoing potential for genetic risks, we developed a comprehensive set of recommendations to conserve genetic diversity of muskellunge (Esox masquinongy) in Wisconsin, and evaluated the extent to which the recommendations can be implemented. Although some details are specific to Wisconsin's muskellunge propagation program, many of the practical issues affecting implementation are applicable to other species and production systems. We developed guidelines to restrict future brood stock collection operations to lakes with natural reproduction and to develop a set of brood lakes to use on a rotational basis within regional stock boundaries, but implementation will require considering lakes with variable stocking histories. Maintaining an effective population size sufficient to minimize the risk of losing alleles requires limiting brood stock collection to large lakes. Recommendations to better approximate the temporal distribution of spawning in hatchery operations and randomize selection of brood fish are feasible. Guidelines to modify rearing and distribution procedures face some logistic constraints. An evaluation of genetic diversity of hatchery-produced fish during 2008 demonstrated variable success representing genetic variation of the source population. Continued evaluation of hatchery operations will optimize operational efficiency while moving toward genetic conservation goals.

Structure and dynamics of noble gas-halogen and noble gas ionic clusters: When theory meets experiment  

NASA Astrophysics Data System (ADS)

As part of this special issue in honor of Gerardo Delgado Barrio, we have reviewed the interplay between experimental and theoretical work on halogen and interhalogen diatomic molecule bonded to one or more noble gas atoms and also ionic clusters consisting of noble gas atoms. Although the Madrid group has worked on many theoretical issues, they have made particularly important contributions to these two topics. Delgado Barrio has often chosen topics for study for which close interactions between theorists and experimentalists are especially useful. During the historical span of the group, we have progressed from approximate models whose goal was to capture the essence of a process even if the details were impossible to reproduce, to an era in which theory is an equal partner with experiment, and, in fact, often provides a detailed understanding beyond that obtained from a careful analysis of state-of-the-art data.

Near-field dispersion modeling for regulatory applications.  

PubMed

This paper evaluates the application of dispersion models to estimate near-field pollutant concentrations in two case studies. The Industrial Source Complex Short-Term Model (ISCST3) was evaluated with hexavalent chromium measurements collected within 100 m of two facilities in Barrio Logan, San Diego, CA. ISCST3 provided reasonable estimates for higher pollutant concentrations but underestimated lower concentrations. To understand the observed distribution of concentrations in Barrio Logan, a recently conducted tracer experiment was analyzed. The tracer, sulfur hexafluoride, was released at ambient temperature from an urban facility at the University of California at Riverside, and concentrations were measured within 20 m of the source. Modeling results indicated that Industrial Source Complex-Plume Rise Model Enhancement and American Meteorological Society/U.S. Environmental Protection Agency Regulatory Model-Plume Rise Model Enhancement overestimated high concentrations and underestimated low concentrations. A diagnostic study with a simple Gaussian dispersion model that incorporated site-specific meteorology was used to evaluate model results. This study found that incorporating lateral meandering for nonbuoyant urban plumes in Gaussian dispersion models could improve concentration estimates even when downwash is not considered. Incorporating a meandering component in ISCST3 resulted in improvements in estimating hexavalent chromium concentrations in Barrio Logan. Credible near-source concentration estimates depend on accurate characterization of emissions, onsite micrometeorology, and a method to account for lateral meandering in the near field.

Schistosomiasis mansoni in the Dominican Republic; prevalence and intensity in various urban and rural communities, 1982-1987.  

PubMed

Surveys to detect foci of schistosomiasis mansoni endemicity in the Dominican Republic were carried out from 1982 to 1987 and showed that the disease is far more widely distributed in the country than previously thought. New foci (San Rafael del Yuma, Batey Palo Bonito, Maicillo, Nisibon and additional barrios in the city of Higuey) were found in the eastern provinces, and other completely new foci (Bayaguana, Sabana Rey (Cotui) and Jarabacoa) in the center of the country and in the National District (Guerra) were also detected. Prevalence rates in the various barrios (sections) of the city of Higuey varied between 7.4% and 24.6%, whereas they were 10.2% in Maicillo, 7.8% in El Valle and 9.9% in El Seibo. The intensity of infection was very low as judged by eggs per gram of feces. Serodiagnosis using the circumoval precipitin test raised the infection rate from that indicated by stool examination, as in Maicillo, or both results were equal, as in Las Palmillas. PMID:2127472

This television show investigates the link between environmental change and the health of Earth as millions of people cope with the spread of pollution. The written summary and video excerpt (1 minute 17 seconds in length) from the television series "Journey to Planet Earth" discuss the "grasshopper effect", in which pollutants released thousands of miles to the south ride the winds until they reach the cold air of the Arctic, where they eventually fall to the earth. In the border communities of Tijuana, Mexico and Barrio Logan, near San Diego, the show describes the efforts of small communities to fight against contamination from industrial polluters. In Uzbekistan, the show describes how people are being poisoned by toxic dust from the Aral Sea, which dried up as water that fed it was diverted for irrigation. And in Palm Springs, California, the show describes the threat to the Salton Sea from salt and chemicals in agricultural runoff.

West Nile Virus Ecology in a Tropical Ecosystem in Guatemala  

PubMed Central

West Nile virus ecology has yet to be rigorously investigated in the Caribbean Basin. We identified a transmission focus in Puerto Barrios, Guatemala, and established systematic monitoring of avian abundance and infection, seroconversions in domestic poultry, and viral infections in mosquitoes. West Nile virus transmission was detected annually between May and October from 2005 to 2008. High temperature and low rainfall enhanced the probability of chicken seroconversions, which occurred in both urban and rural sites. West Nile virus was isolated from Culex quinquefasciatus and to a lesser extent, from Culex mollis/Culex inflictus, but not from the most abundant Culex mosquito, Culex nigripalpus. A calculation that combined avian abundance, seroprevalence, and vertebrate reservoir competence suggested that great-tailed grackle (Quiscalus mexicanus) is the major amplifying host in this ecosystem. West Nile virus transmission reached moderate levels in sentinel chickens during 2007, but less than that observed during outbreaks of human disease attributed to West Nile virus in the United States.

Subtle genetic connectivity between Mexican Caribbean and south-western Gulf of Mexico reefs: the case of the bicolor damselfish, Stegastes partitus  

NASA Astrophysics Data System (ADS)

Efficient reef management strategies rely on detailed knowledge of biological exchange dynamics. At present, available connectivity information on Mexican Atlantic reefs is scarce, particularly concerning the Veracruz Reef System (VRS), which is located in the south-western Gulf of Mexico. This study used a hierarchically nested sampling design to evaluate the levels of genetic connectivity both within and between the Mexican Caribbean (MC) and VRS reef regions; all of the studied reefs are marine protected areas. Microsatellites were used as genetic markers, and bicolor damselfish ( Stegastes partitus) recruits were used as a biological model. The paired genetic differentiation index between regions ( Fst (ENA) = 0.008) was lower than the global index ( Fst (ENA) = 0.027), suggesting that the stronger restrictions to gene flow may be located inside the regions rather than between them. The AMOVA results supported this explanation, as the differences were only non-significant between regions. In the VRS, Santiaguillo reef was associated with low genetic connectivity levels, whilst within the MC region the group formed by Chinchorro Bank and Cozumel exhibited a restriction to gene flow with Puerto Morelos, their northernmost reef. Despite their spatial separation, reefs from different regions (Puerto Morelos and Anegada de Adentro) showed the lowest, albeit significant, genetic difference, meaning that a subtle genetic connectivity exists at the regional scale. The detected composite flow pattern is likely related to self-recruitment and cohesive dispersal processes interacting with current patterns, which may favour genetic connections under specific conditions. The results presented here suggest that coral reef management in the Mexican Atlantic Ocean should consider large scale measures in addition to appropriate local actions to protect reef fish populations.

[Coproantigens detection for the diagnosis of canine Echinococcosis in the border area of La Quiaca-Villazón].  

PubMed

Cystic Echinococcosis is a major public health issue. Immunodiagnostic techniques based on the identification of parasite antigens in dog dry faeces have been developed as alternatives for the surveillance of canine Echinococcosis. The environmental conditions favouring the parasite cycle were met in the border of La Quiaca-Villazón, given the presence of definitive (dog) and intermediate hosts (sheep and goats). The most important activity in La Puna is sheep and goat rearing; slaughtering is carried out almost exclusively in the field by sheep's owners, and preventive health measures do not apply. The aim of this study was to determine the presence of dogs parasitized by Echinococcus granulosus in this border region. A hundred and sixty eight (168) stool specimens were collected during 2006. La Quiaca samples were taken from the following selected areas: the semi-rural area of Barrios, the rural areas of Santa Catalina, Yavi Chico, El Portillo, Pumahuasi and Cara Cara and the urban area of La Quiaca; selected urban areas in Villazón and the semi-rural area of Ojo de Agua, Lampaya and Matancillas. The samples were analyzed by copro-ELISA -Western blot test. The cities of San Francisco and Barrios had a prevalence of 14.3% and 6.7%, respectively. A prevalence of 3.4% was observed in the urban area of Villazón, which indicates that dogs become infected in the rural areas and bring the risk into the city. Lampaya showed a prevalence of 30%. These findings suggest the need to implement strategies for the control of hydatidosis, both in urban and rural areas to avoid the increase and spread of Echinococcosis in the region. PMID:24165137

"Katiwala": trustee of community health.  

PubMed

The setting up of a medical cooperative in a squatter community in Davao City, Philippines, and the training of women from the community to serve as paramedical health visitors and family planning workers, is described. The clinic charges each family a small fee and sells drugs at cost. The health visitor program was initiated by the poor families themselves to reach those who could not come to the clinic. The 1st groups trained chose the name Kaunaunahang Katiwala ng Kalusugan, or First Trustees of Health, and they are called katiwala for short. Since 1973 about 80 of these women, usually about 30 years of age, with home and family responsibilities, and of low educational background, have bee n trained. The dialogic method of Paolo Fraire of Brazil is used, which focuses on the native intelligence of the student and emphasizes a mutual learning process on the part of both teacher and student. Upon graduation the katiwala take care of minor ailments, refer major problems to the clinic, distribute family planning information, and encourage sanitation and good health practices. The barrios are divided into districts and 2 katiwala assigned to each. They receive some compensation. The program has proved it is possible to train persons with little education to be effective health workers and free physicians and nurses for more serious cases. PMID:12277098

Adjustment of the tree-ring response of Juniperus thurifera to climate in the Western Mediterranean region  

NASA Astrophysics Data System (ADS)

Juniperus thurifera L. is a long-lived conifer tree endemic to western Mediterranean region. It is well adapted to continental Mediterranean weather conditions such as negative winter temperatures or summer drought and is capable to maintain the photosynthetic activity all year round, making it a suitable species to study tree-ring sensitivity to climate change. In this work we have used tree-ring width data of J. thurifera trees from six stands located in northern Spain (Soria, Barrios de Luna and Desert of Monegros) and High Atlas in Morocco (Armd, Oukaimeden and Ourika) and correlated with climatic information (temperature and precipitation) from the Climate Research Unity (CRU) database. We have evaluated separately the growth patterns and climatic response of the populations from Spain and Morocco as they showed distinct seasonal dependence to temperature and precipitation. Afterwards, according to the length of both databases (ring-width and surface climate variables), we evaluated the role played by the climatic variables on the species growth pattern through time. We observed an increase of growth sensitivity to summer drought in Spain, whereas such sensitivity was not verify in Morocco"

[Legal strategies against violence in the households of urban communities of Managua].  

PubMed

Although domestic violence against women has a long history in Nicaragua, it did not receive national public attention until a 1985 study that was conducted by the Legal Office for Women (OLM) of the Sandinista Women¿s organization. AMNLAE showed that 51% of the cases in which women sought legal assistance, related to domestic violence. The Nicaraguan law does not specifically consider domestic violence, and no previous studies allow comparison with current statistics. This work describes two juridical strategies to resist violence against women: 1) an effort, largely initiated by lawyers and social scientists participating in the OLM, to reform the formal juridical system through new legislation making domestic violence a crime; 2) a strategy initiated by activists in poor urban barrios in the municipal districts north of Managua, who developed locally based informal mechanisms including a court of women, assignment of lawyers to work with battered women in the local police station, and organization of community networks of resistance by the lawyers. The development of the process during the Sandinista period of the 1980s and transformation under the Violeta Chamorros regime after 1990 are analyzed. The complex interaction of the AMNLAE with the Sandinista regime and the redefinition of the limits among private and public domains of urban neighborhoods are examined. PMID:12295310

Psychosociocultural perspectives on chronic cannabis use: the Costa Rican follow-up.  

PubMed

The social standing of marijuana use in Costa Rica becomes important as one examines the results of this study. Before 1968, marijuana use itself defined Costa Rican consumers of the drug as lower class. Its coming to fashionability among Costa Rican upper-middle-class youths during the late 1960's and early 1970's temporarily blurred marijuana's class identification. Nevertheless, the lower-class users' dress, speech and style of use kept them distinct from these youths. In 1986, working-class users participating in the present intensive study still occupied the lowest positions in the Costa Rican social strata. Their marijuana use does not appear to be a major factor in blocking upward mobility. The social stations in which users were raised were more powerful in determining their present fates than taking up or not taking up marijuana use. Users speak the language differently, employing a mix of lexical changes and wordplay to keep the decent Costa Ricans out of their clandestine business. Smokers of marijuana also dress differently from other Costa Ricans and tend to live in disreputable barrios, according to the stereotype. The Costa Rican image of a marijuana smoker is one of a streetwise, corrupt and uncomfortably distinctive character who is not to be trusted. The main problem in assessing the relationship between marijuana use and the human condition of marijuana users is the pervasive influence of the general social disapproval of marijuana smoking in Costa Rican society.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:3392632

Timing of Multiple Shock Waves in Cryogenic-Deuterium Targets  

NASA Astrophysics Data System (ADS)

Achieving ignition and high performance from inertial confinement fusion targets requires optimization of the implosion dynamics. Critical to this is the timing of a sequence of shock waves that are used to condition the shell and fuel as they are imploded. The National Ignition Campaign (NIC) specifications for ignition designs require that these shock waves coalesce at precise intervals that must be controlled to ˜50 ps. The plan for ignition includes optimization experiments that use surrogate targets to measure the timing and strength of shocks, then iterating the drive profile to achieve the required precision. These surrogate targets use an ignition-style capsule fitted with a deuterium-filled re-entrant cone embedded in that shell. The shocks are observed in flight through a transparent window using optical diagnostics. We report on OMEGA experiments that demonstrated this shock-timing technique in liquid deuterium driven by hohlraums that reached radiation temperatures of 165 eV. Multiple spherically converging shocks are also being diagnosed and timed in direct-drive deuterium-filled spheres to optimize cryogenic implosions and validate hydrodynamic simulations. This work was supported by U.S. Department of Energy Office of Inertial Confinement Fusion under Cooperative Agreement No. DE-FC52-08NA28302. Contributors: V.N. Goncharov, S.X. Hu, M.A. Barrios, D.E.

Refractive Index of Lithium Fluoride Ramp Compressed to 800 GPa  

NASA Astrophysics Data System (ADS)

The compression of materials to high pressure can alter their optical properties in ways that provide insight into the resulting structural changes. Under strong shock compression, transparent insulators transform into conducting fluids as a result of pressure-induced reduction of the band gap and thermal promotion of electrons across that gap. LiF is ramp compressed to 800 GPa on the Omega Laser Facility without generating shocks, producing high pressures at significantly lower temperatures than would be created by shock waves. Ramp compressed lithium fluoride (LiF) is observed to remain transparent to 800 GPa, pressures seven times higher than previous shock compression experiments. The ramp-compressed refractive index of LiF is measured at pressures up to 800 GPa and depends linearly on density. This is the highest-pressure refractive index measurement made to date. The linear dependence of the refractive index and density is examined using a single oscillator model. This model indicates that the linear behavior is a result of monoatomic closure of the band gap. Extrapolation of these results indicates that the band gap closure (metallization) will be greater than 4,000 GPa. The high metallization pressure of LiF is attributed to its large band gap and isoelectronic counterparts that exhibit high metallization pressures. The observed high-pressure transparency and measurement of LiF refractive index enables advancement of in situ experiments to higher-pressure regimes. In collaboration with T.R. Boehly (LLE), M.A. Barrios (LLE -- now at LLNL), D.D. Meyerhofer (LLE), J.H. Eggert (LLNL), R.F. Smith (LLNL), D.G. Hicks (LLNL), P.M. Celliers (LLNL), and G.W. Collins (LLNL).

Stabilization and rovibronic spectra of the T-shaped and linear ground-state conformers of a weakly bound rare-gas-homonuclear dihalogen complex: He...Br2  

NASA Astrophysics Data System (ADS)

Laser-induced fluorescence spectra of Br2 entrained in a He supersonic expansion have been recorded in the Br2 B-X, 8-0, 12-0, and 21-0 spectral regions at varying downstream distances, and thus different temperature regimes. Features associated with transitions of the T-shaped and linear He...Br2(X,?''=0) complexes are identified. The changes in the relative intensities of the T-shaped and linear features with cooling in the expansion indicate that the linear conformer is energetically more stable than the T-shaped conformer. A He+Br2(X,?''=0) ab initio potential-energy surface, computed at the coupled cluster level of theory with a large, flexible basis set, is used to calculate the binding energies of the two conformers, 15.8 and 16.5 cm-1 for the T-shaped and linear complexes, respectively. This potential and an excited-state potential [M. P. de Lara-Castells, A. A. Buchachenko, G. Delgado-Barrio, and P. Villareal, J. Chem. Phys. 120, 2182 (2004)] are used to calculate the excitation spectra of He...79Br2(X,?''=0) in the Br2 B-X, 12-0 region. The calculated spectra are used to make spectral assignments and to determine the energies of the excited-state intermolecular vibrational levels accessed in the observed transitions. Temperature-dependent laser-induced fluorescence spectra and a simple thermodynamic model [D. S. Boucher, J. P. Darr, M. D. Bradke, R. A. Loomis, and A. B. McCoy, Phys. Chem. Chem. Phys. 6, 5275 (2004)] are used to estimate that the linear conformer is 0.4(2) cm-1 more strongly bound than the T-shaped conformer. Two-laser action spectroscopy experiments reveal that the binding energy of the linear He...79Br2(X,?''=0) conformer is 17.0(8) cm-1, and that of the T-shaped He...79Br2(X,?''=0) conformer is then 16.6(8) cm-1, in good agreement with the calculated values.

An optimized full-configuration-interaction nuclear orbital approach to a ``hard-core'' interaction problem: Application to (3He)N-Cl2(B) clusters (N<=4)  

NASA Astrophysics Data System (ADS)

An efficient full-configuration-interaction nuclear orbital treatment has been recently developed as a benchmark quantum-chemistry-like method to calculate ground and excited ``solvent'' energies and wave functions in small doped ?Eest clusters (N<=4) [M. P. de Lara-Castells, G. Delgado-Barrio, P. Villarreal, and A. O. Mitrushchenkov, J. Chem. Phys. 125, 221101 (2006)]. Additional methodological and computational details of the implementation, which uses an iterative Jacobi-Davidson diagonalization algorithm to properly address the inherent ``hard-core'' He-He interaction problem, are described here. The convergence of total energies, average pair He-He interaction energies, and relevant one- and two-body properties upon increasing the angular part of the one-particle basis set (expanded in spherical harmonics) has been analyzed, considering Cl2 as the dopant and a semiempirical model (T-shaped) He-Cl2(B) potential. Converged results are used to analyze global energetic and structural aspects as well as the configuration makeup of the wave functions, associated with the ground and low-lying ``solvent'' excited states. Our study reveals that besides the fermionic nature of 3He atoms, key roles in determining total binding energies and wave-function structures are played by the strong repulsive core of the He-He potential as well as its very weak attractive region, the most stable arrangement somehow departing from the one of N He atoms equally spaced on equatorial ``ring'' around the dopant. The present results for N=4 fermions indicates the structural ``pairing'' of two 3He atoms at opposite sides on a broad ``belt'' around the dopant, executing a sort of asymmetric umbrella motion. This pairing is a compromise between maximizing the 3He-3He and the He-dopant attractions, and suppressing at the same time the ``hard-core'' repulsion. Although the He-He attractive interaction is rather weak, its contribution to the total energy is found to scale as a power of three and it thus increasingly affects the pair density distributions as the cluster grows in size.

Infant feeding practices in a poor district of Santo Domingo.  

PubMed

During August-December 1989, in the Dominican Republic, local health promoters interviewed 103 primary caretakers and took anthropometric measurements from 103 children aged 3 years and under during home visits in three poor neighborhoods of Los Alcarrizos (Alto de Chavon, Barrio Landia, and Pueblo Nuevo) to examine infant feeding practices. 95% of the mothers had started breast feeding. The median duration of breast feeding was 7.5 months. Almost 33% had quit breast feeding by 3 months. Perception of insufficient milk was the leading reason for early discontinuation of exclusive breast feeding. The local pharmacies in all three communities offered powdered milk. About 25% of mothers began using breast milk substitutes within the first week. A non-infant formula milk powder was the most commonly used breast milk substitute. 30% of mothers stored prepared milk for later feeds, as long as half a day. Only 13% of households had a refrigerator. The most frequently used first weaning foods were orange juice, lime juice, and beans. 76% of mothers had used or were currently using baby bottles. 95% of them reported washing the bottle in boiling water. The median age of introducing the baby bottle was 3 days. Only 44% of mother covered prepared food during storage. The most commonly eaten foods among children aged at least 1 year were milk, beans, rice, and citrus fruits. Yet the children did not eat all these foods daily. 18% of 1-2 year olds and 13% of 2-3 year olds did not eat meats and alternatives regularly. 7% of 1-2 year olds and 10% of 2-3 year olds did not eat fruits and vegetables regularly. 4% of 1-2 year olds and 3% of 2-3 year olds did not eat breads and cereals regularly. About 14% of all children were not consuming any milk at the time of the survey. These findings will be used to refine nutrition education programs in the district to make them more effective.

The iron-coating role on the oxidation kinetics of a pyritic sludge doped with fly ash  

NASA Astrophysics Data System (ADS)

The present study examines the processes that control the oxidation attenuation of a pyrite-rich sludge (72 wt% pyrite) from the Iberian Pyrite Belt by the buffer capacity of a fly ash from Los Barrios power station (S Spain), using saturated column experiments. In addition, in order to understand the behaviour of both materials inside these experiments, a fly-ash leaching test and flow-through experiments with pyritic sludge were carried out. The fly-ash leaching test showed that after leaching this material with a slightly acid solution (Millipore MQ water; pH 5.6) the pH raised up to 10.2 and that the metals released by the fly-ash dissolution did not increase significantly the metal concentrations in the output solutions. The flow-through experiments with the pyritic sludge were performed at pH 9, 22 °C and O 2 partial pressure of 0.21 atm, to calculate the dissolution rate of this residue simulating the fly-ash addition. In the experiments Fe bearing oxyhydroxides precipitated as the sludge dissolved. In two non-stirred experiments the iron precipitates formed Fe-coatings on the pyrite surfaces preventing the interaction between the oxidizing agents and the pyrite grains, halting pyrite oxidation (this process is known as pyrite microencapsulation), whereas in two stirred experiments, stirring hindered the iron precipitates to coat the pyrite grains. Thus, based on the release of S (aqueous sulphate) the steady-state pyritic sludge dissolution rate obtained was 9.0 ± 0.2 × -11 mol m -2 s -1. In the saturated column experiments, the sludge dissolution was examined at acidic and basic pH at 22 °C and oxygen-saturated atmosphere. In a saturated column experiment filled with the pyritic sludge, pyrite oxidation occurred favourably at pH approx. 3.7. As the leachates of the fly ash yielded high basic pH, in another saturated column, consisting of an initial thick layer of fly-ash material and a layer of pyritic sludge, the pyrite dissolution took place at pH approx. 10.45. In this experiment, iron was depleted completely from the solution and attenuation of the sludge oxidation was produced in this conditions. The attenuation was likely promoted by precipitation of iron-bearing phases upon the pyritic surface forming Fe-coatings (of ferrihydrite and/or Fe(III) amorphous phases) that halted the pyrite oxidation (as in non-stirred flow-through experiments). Results suggest that buffering capacity of fly ash can be used to attenuate the pyrite-rich sludge oxidation.

O método Grade of Membership (GoM) tem sido cada vez mais utilizado por demógrafos brasileiros e tem a vantagem de possuir um parâmetro que mensura a heterogeneidade individual, com base nas correlações não-observáveis entre as categorias de resposta das variáveis de interesse, gerando um medida do grau de pertencimento de cada indivíduo a perfis extremos. Alguns autores, contudo, chamam atenção para questões importantes na calibragem dos modelos finais que utilizam o programa GoM versão 3.4, como o problema de identificabilidade - soluções múltiplas para parâmetros estimados. Neste artigo, é sugerido um procedimento capaz de identificar um modelo final com solução única que descreva os tipos puros mais fidedignos à base de dados, em uma tentativa de otimização. Para ilustrar esse processo, utilizou-se uma base de dados correspondente a um levantamento econômico e sociodemográfico de uma população de pequenos agricultores residentes ao longo da Rodovia Transamazônica, no Estado do Pará. Também identificou-se a existência de instabilidade nos parâmetros estimados pelo programa GoM 3.4, sendo proposto um método de estabilização de seus valores. Com esses procedimentos combinados, os usuários do programa GoM 3.4 poderão descrever sua base de dados de forma mais adequada e responder às críticas sobre questões de identificabilidade e estabilidade dos modelos resultantes. Essas soluções empíricas são relevantes por afetarem cálculos de prevalência e de incidência de eventos de interesse, além de trazerem consequências importantes sobre o ponto e o momento corretos para intervenções de políticas públicas ou de planejamento prospectivo em análises de projeção.

Los modelos bidimensionales para describir hojas de corriente de alta simetría no suministran una descripción detallada de las regiones donde la difusión es considerablemente importante. Tal es el caso de los modelos desarrollados en la década del '60 por Sweet, Parker, Petschek y Sonnerup. En esta comunicación presentamos una solución de las ecuaciones MHD en el entorno del origen, construyendo series bidimensionales para todas las magnitudes físicas involucradas. Valiéndonos de la alta simetría y de las características del problema, logramos reducir el número de coeficientes a calcular. Utilizamos un programa autoconsistente para extender el cálculo a regiones vecinas con difusión moderada o despreciable.

Groundwater-flow modeling in the Yucatan karstic aquifer, Mexico  

NASA Astrophysics Data System (ADS)

The current conceptual model of the unconfined karstic aquifer in the Yucatan Peninsula, Mexico, is that a fresh-water lens floats above denser saline water that penetrates more than 40 km inland. The transmissivity of the aquifer is very high so the hydraulic gradient is very low, ranging from 7-10 mm/km through most of the northern part of the peninsula. The computer modeling program AQUIFER was used to investigate the regional groundwater flow in the aquifer. The karstified zone was modeled using the assumption that it acts hydraulically similar to a granular, porous medium. As part of the calibration, the following hypotheses were tested: (1) karstic features play an important role in the groundwater-flow system; (2) a ring or belt of sinkholes in the area is a manifestation of a zone of high transmissivity that facilitates the channeling of groundwater toward the Gulf of Mexico; and (3) the geologic features in the southern part of Yucatan influence the groundwater-flow system. The model shows that the Sierrita de Ticul fault, in the southwestern part of the study area, acts as a flow barrier and head values decline toward the northeast. The modeling also shows that the regional flow-system dynamics have not been altered despite the large number of pumping wells because the volume of water pumped is small compared with the volume of recharge, and the well-developed karst system of the region has a very high hydraulic conductivity. Résumé. Le modèle conceptuel classique de l'aquifère karstique libre de la péninsule du Yucatan (Mexique) consiste en une lentille d'eau douce flottant sur une eau salée plus dense qui pénètre à plus de 40 km à l'intérieur des terres. La transmissivité de l'aquifère est très élevée, en sorte que le gradient hydraulique est très faible, compris entre 7 et 10 mm/km dans la plus grande partie du nord de la péninsule. Le modèle AQUIFER a été utilisé pour explorer les écoulements souterrains régionaux dans cet aquifère. La zone karstifiée a été modélisée en posant l'hypothèse qu'il fonctionne hydrauliquement comme un milieu poreux granulaire. Au cours de la calibration, les hypothèses suivantes ont été testées: (1) les phénomènes karstiques jouent un rôle important dans le système aquifère, (2) un anneau ou une ceinture de dépressions dans la région est la manifestation d'une zone à forte transmissivité qui permet l'écoulement en conduits de l'eau souterraine en direction du Golfe du Mexique, et (3) la situation géologique dans la partie sud du Yucatan détermine les écoulements souterrains. Le modèle montre que la faille de la Sierrita de Ticul, dans la partie sud-ouest de la région étudiée, joue le rôle de barrière et que les valeurs de la piézométrie décroissent en direction du nord-est. La modélisation montre également que la dynamique du système aquifère à l'échelle régionale n'a pas été modifiée malgré le grand nombre de puits de pompage, parce que le volume pompé est faible en comparaison du volume de recharge; en outre, le réseau karstique très bien développé dans cette région possède une très forte conductivité hydraulique. Resumen. El modelo conceptual actual del acuífero cárstico no confinado de la Península de Yucatán (México) es el de un lentejón de agua dulce flotando sobre agua salada, más densa, la cual penetra más de 40 kilómetros tierra adentro. Debido a la alta conductividad hidráulica del acuífero, existe un gradiente hidráulico muy bajo cuyo rango está entre 7 y 10 milímetros por kilómetro en la porción norte de la península. Se utilizó el código AQUIFER para investigar el sistema de flujo de las aguas subterráneas a escala regional en el acuífero. La zona carstificada se modeló suponiendo que actúa hidráulicamente como un medio poroso granular. Como parte de la calibración, se probaron las siguientes hipótesis: (1) las características cársticas desempeñan un papel importante en el sistema de flujo de agua subterránea (2) un anillo o cinturón de sumideros en el área e

From surfaces to magnetic properties: special section dedicated to Juan Rojo  

NASA Astrophysics Data System (ADS)

Surface physics and magnetism, in particular the connection between surface defects, reduced dimensionality or size, crystal structure, electronic density of states and the mechanical and magnetic properties of solids, were always at the core of Juan Rojo's scientific interest and output. Both fields seem to meet at the nanoscale, a privileged playing field which is ideal for testing theoretical concepts, exploring new physics or probing a wealth of new, stunning and unheard-of applications. Upon reducing size or dimensionality, either in bulk systems or in thin films, surfaces and surface effects are telling. Thus, for instance, an ultra-thin coating can make nanoparticles of non-magnetic materials exhibit magnetic behaviour; or atomic steps can modify the local mechanical properties of a metallic single crystal. In this special section there are eight invited papers by disciples and close collaborators of Juan Rojo, that cover an ample spectrum of the above mentioned topics. The first paper, by Palacio et al, investigates the temperature and oxygen partial pressure conditions for FeO mono- and bi-layer growth on Ru(0001). The following paper, by Cortés-Gil et al, reports on the dramatic change in the electric resistivity of the manganite perovskite (La0.5Ca0.5)z MnO3 as a function of Ca content, an effect related to the removal of a charge-ordered state and a magnetic transition. Baeza et al study biomaterials for bone cancer treatment and skeletal reinforcing, as well as targeted magnetic nanoparticles used for intracell hyperthermia in cancer therapies. In the following paper, Marcano et al, assisted by a multi-technique approach, revisit the extraordinarily rich magnetic phase diagram of the Kondo system CeNi1- x Cux down to 100 mK temperatures. The magnetic field dependence of the martensitic transition temperature of the meta-magnetic shape memory alloy Ni50Mn34.5In15.5 in a crystalline and amorphous phase, in fields up to 13 T, is the subject of the paper by Barandiarán et al. In the following paper, Crespo et al review the effect of organic and inorganic coatings on magnetic nanoparticles, showing that the coating can tune the magnetic properties of metallic and oxide nano-sized particles. Barja et al report on ordered magnetic ion structures formed by evaporation of Mn and Fe on self-assembled layers of tetracyanoquinodimethane (TCNQ) molecules on Cu(111). Finally, Rodríguez de la Fuente et al investigate the role of surface defects on the physico-chemical properties of metals and oxides in a variety of scenarios, showing how the surface controls the mechanical properties probed at the nanoscale or the chemical reactivity. Acknowledgments The editors are grateful to all the invited contributors to this special section of Journal of Physics: Condensed Matter . We also thank the staff of IOP Publishing for handling the administrative matters and the refereeing process, and for their patience and helpful disposition.

Hoje este sonho se torna uma realidade. O Brasil tem tido uma política de pesquisa e de pós-graduação bem sucedida. Estamos formando 7000 doutores por ano e produzimos 1,5% da ciência mundial. Nosso desafio, hoje, é associar a esta capacidade de gerar conhecimento também a capacidade de usar o conhecimento em beneficio da sociedade. A Astronomia não é exceção. Temos 7 programas de pós-graduação em nível de doutorado e 11 em nível de mestrado. O telescópio SOAR será o principal instrumento que sustentará estes programas nas próximas décadas. A inauguração do telescópio SOAR simboliza de forma concreta e decidida o apoio do MCT, do CNPq e da FAPESP para o financiamento à pesquisa básica em nosso país. O Laboratório Nacional de Astrofísica, criado a cerca de 20 anos pelo CNPq, a par do Laboratório Nacional de Luz Sincrotron, são até hoje, os únicos laboratórios nacionais do Brasil e ambos voltados basicamente ao avanço do conhecimento. Os vinte anos de existência do LNA foram decisivos para a estruturação da comunidade astronômica no Brasil e para a construção das parcerias como o SOAR.

La salud en personas con discapacidad intelectual en Espa?a: estudio europeo POMONA-II  

PubMed Central

Introducción Estudios internacionales demuestran que existe un patrón diferenciado de salud y una disparidad en la atención sanitaria entre personas con discapacidad intelectual (DI) y población general. Objetivo Obtener datos sobre el estado de salud de las personas con DI y compararlos con datos de población general. Pacientes y métodos Se utilizó el conjunto de indicadores de salud P15 en una muestra de 111 sujetos con DI. Los datos de salud encontrados se compararon según el tipo de residencia de los sujetos y se utilizó la Encuesta Nacional de Salud 2006 para comparar estos datos con los de la población general. Resultados La muestra con DI presentó 25 veces más casos de epilepsia y el doble de obesidad. Un 20% presentó dolor bucal, y existió una alta presencia de problemas sensoriales, de movilidad y psicosis. Sin embargo, encontramos una baja presencia de patologías como la diabetes, la hipertensión, la osteoartritis y la osteoporosis. También presentaron una menor participación en programas de prevención y promoción de la salud, un mayor número de ingresos hospitalarios y un uso menor de los servicios de urgencia. Conclusiones El patrón de salud de las personas con DI difiere del de la población general, y éstas realizan un uso distinto de los servicios sanitarios. Es importante el desarrollo de programas de promoción de salud y de formación profesional específicamente diseñados para la atención de personas con DI, así como la implementación de encuestas de salud que incluyan datos sobre esta población.

Barreras y Facilitadores en el Reclutamiento y la Retenci?n de Parejas Heterosexuales en Intervenciones Preventivas en VIH/SIDA  

PubMed Central

Compendio El Reclutamiento y la Retención (R&R) de participantes es fundamental para el éxito de estudios y para el desarrollo de intervenciones preventivas. El R&R de participantes determina la validez y efectividad de estos programas. En este trabajo examinamos algunos de los factores que facilitan y dificultan el R&R en los proyectos preventivos y ofrecemos algunas alternativas para mejorar los índices de R&R. Realizamos dos estudios, en el primero administramos el Instrumento de Informatión, Motivatión y Conductas-Español (IIMC-E) a un grupo de 26 parejas heterosexuales (52 participantes). En el segundo, entrevistamos a 5 parejas VIH discordantes (10 participantes). Encontramos que el 75% de los/las participantes indicó que su trabajo era una de las principales barreras que dificultan la asistencia a las actividades. Otras barreras son las responsabilidades laborales y familiares. Encontramos que la principal barrera fue el miedo a la revelación del estado serlógico. Los principales facilitadores del R&R son la coordinación adecuada y el seguimiento telefónico ofrecido por parte del personal del proyecto. Concluimos que en el desarrollo e implantación de programas de prevención el investigador/a debe tomar en cuenta la adaptación de aspectos logísticos como la disponibilidad y las necesidades particulares de los/las participantes.

[Barriers and Facilitators in the Recruitment and Retention of Heterosexual Couples for Preventive Interventions.  

PubMed

El Reclutamiento y la Retención (R&R) de participantes es fundamental para el éxito de estudios y para el desarrollo de intervenciones preventivas. El R&R de participantes determina la validez y efectividad de estos programas. En este trabajo examinamos algunos de los factores que facilitan y dificultan el R&R en los proyectos preventivos y ofrecemos algunas alternativas para mejorar los índices de R&R. Realizamos dos estudios, en el primero administramos el Instrumento de Informatión, Motivatión y Conductas-Español (IIMC-E) a un grupo de 26 parejas heterosexuales (52 participantes). En el segundo, entrevistamos a 5 parejas VIH discordantes (10 participantes). Encontramos que el 75% de los/las participantes indicó que su trabajo era una de las principales barreras que dificultan la asistencia a las actividades. Otras barreras son las responsabilidades laborales y familiares. Encontramos que la principal barrera fue el miedo a la revelación del estado serlógico. Los principales facilitadores del R&R son la coordinación adecuada y el seguimiento telefónico ofrecido por parte del personal del proyecto. Concluimos que en el desarrollo e implantación de programas de prevención el investigador/a debe tomar en cuenta la adaptación de aspectos logísticos como la disponibilidad y las necesidades particulares de los/las participantes.

PREFACE: Special issue: Proceedings of the Joint 19th AIRAPT and 41st EHPRG International Conference on High Pressure Science and Technology (Bordeaux, 7--11 July 2003)  

NASA Astrophysics Data System (ADS)

This volume is the outcome of a three-day meeting held 7-10 August, 2004 in St Adèle, Québec honouring Michael F Thorpe, Foundation Professor of Physics, Chemistry and Biophysics at Arizona State University. Michael Thorpe has made many important contributions to condensed matter physics, broadly defined. From the famous Weaire and Thorpe Hamiltonian in 1971 [1] to rigidity percolation theory [2] and flexibility in proteins [3], he has always provided highly original solutions to difficult problems. He has also demonstrated an uncommon gift for selecting and solving problems of remarkably broad significance (for example, rigidity theory is now a powerful tool in glasses, microelectronics and proteins). Throughout his career, Mike has also made a point of establishing contact with scientists from all disciplines and origins, organizing tens of conferences and maintaining a very active visitor's program both at Michigan State University, where he spent 25 years, and, now, at Arizona State University, where he moved a year ago. It is therefore not surprising that the participants, all with scientific or personal links with Mike, usually both, came from Europe, Asia and North America to celebrate the 60th birthday of an eminent physicist and friend. Reflecting the impact of Mike's work across the traditional scientific boundaries, the meeting included contributions ranging from studies of concrete by Ed Garboczi (NIST), a hybrid VCA/CPA treatment of the Hubbard model presented by Sir Roger Elliott (Oxford) to the assembly process of viral capsids by Brandon Hespenheide (ASU). Especially memorable talks were given by Rafael Barrio (with his photogenic striped imperial fish), Alex Kolobov (presenting impressive scientific results using equally impressive computer graphics), and Dick Zallen, for a remarkably good `roast' of the honoree and work with his daughter (a molecular biologist) on biophysics. The meeting had an unusual warmth befitting the birthday celebration, and was also by any measure a scientific success, with innumerable questions and discussions among this diverse group, and the scholarly contributions in this volume. We thank the participants, and Dr Richard Palmer, the Publisher of Journal of Physics: Condensed Matter and his staff for working to make this volume appear very quickly, thereby increasing the value of the papers to the community. We would also thank the Office of the vice-president for research at Université de Montréal, the Department of Physics and Astronomy at Arizona State University, the Department of Physics and Astronomy at Ohio University and the Canada Research Chair Program for financial assistance that made the meeting more enjoyable. We were both pleased to be part of this delightful occasion, and wish to take this last opportunity to wish Mike a happy birthday, and urge him to even greater achievements in coming years.

Recent KBO (Pluto/Charon and beyond, including Quaoar) Occultation Observations by the Williams College Team as part of the Williams-MIT Collaboration  

NASA Astrophysics Data System (ADS)

The Williams College-MIT collaboration has observed numerous occultations of stars by Pluto/Charon and other Kuiper-belt objects (www.stellaroccultations.info), since its establishment three decades ago with an attempted discovery of Neptune's rings in 1983. In this paper, we describe several recent occultation observations, both successful and (for reasons of path uncertainties and/or weather) unsuccessful. Light curves made or arranged by Williams College faculty and students were used together with light curves by MIT colleagues and others to study Pluto's atmosphere and Charon's size, to discover one of the highest-known solar-system albedos (KBO 55636), and to attempt to study 1000-km-diameter Quaoar. Observations discussed include light curves for KBO 55636 on 9 October 2009 from Hawaii; Pluto on 3/4 July 2010 from Chile, 22 May 2011 from Williamstown, Massachusetts, 23 June 2011 from Hawaii (in support of SOFIA observations of Pluto's atmosphere, discussed in an article in press in AJ and of the pair of Pluto/Charon occultations of the same star), and 4 May 2013 (Bosh et al., this conference) and 15 July 2013 from Williamstown; Charon on 15 June 2013 from Williamstown; Quaoar from a picket fence ranging from Chile through Venezuela (with a detection there) to Massachusetts on July 8/9 and in South Africa on 12 July 2013. This work was supported in part by NASA Planetary Astronomy grants NNX08AO50G and NNH11ZDA001N to Williams College, NNX10AB27G to MIT, and USRA grant #8500-98-003 to Lowell Observatory.

Curva de rotación de la Galaxia Eso 321-25  

NASA Astrophysics Data System (ADS)

Se presenta la curva de rotación de esta galaxia, generada a partir de espectros obtenidos con el Espectrógrafo Multifunción del telescopio de 1.54 m de Bosque Alegre. El análisis de las curvas de velocidad radial obtenidas muestra que el núcleo no coincide con el centro de simetría de las mismas, lo que es consistente con el aspecto morfológico exhibido por la galaxia en imágenes de banda ancha. En estas últimas, el núcleo muestra una estructura peculiar y no coincidiría con el centro geométrico del disco aparente. Los flujos relativos de líneas (H? /[NII]? 6583 y [SII]? 6731/? 6716) indicarían niveles de excitación y densidad electrónica normales en regiones HII, aún en la zona nuclear. Este trabajo forma parte de un programa de estudio de cinemática, excitación y densidad electrónica del gas ionizado en galaxias peculiares del Atlas de Galaxias Australes de Sérsic.

Autoguía para el telescopio 2,15 mts de CASLEO  

NASA Astrophysics Data System (ADS)

Se está desarrollando un sistema de autoguía para el telescopio de 2,15 mts. El mismo se realizará aprovechando el Offset Guider. Al ocular móvil de éste se vinculará alguna cámara digital (ST4-ST7-CH250) para lograr la visión del objeto. El funcionamiento del equipo será el siguiente: primero, dadas las coordenadas del objeto a observar, se tomarán las coordenadas del telescopio para que, a través de una base de datos, se determine un campo de objetos que sirvan para la cámara de visión, luego, la PC obtendrá el offset entre la estrella de observación y la estrella seleccionada como guía, este valor será trasladado a los motores que posicionarán en forma automática el ocular. Una vez que la estrella es visualizada en la cámara (monitor de PC ) se correrá el programa que guiará el telescopio automáticamente.

Terrestrial Carbon Fluxes from Deforestation in the Brazilian Amazon and Cerrado Regions Predicted from MODIS Satellite Data and Ecosystem Modeling  

NASA Astrophysics Data System (ADS)

The NASA-CASA (Carnegie Ames Stanford Approach) simulation model based on satellite observations of monthly vegetation cover from the Moderate Resolution Imaging Spectroradiometer (MODIS) was used to estimate tropical forest and savanna (Cerrado) carbon pools for the Brazilian Amazon region over the period 2000-2004. Adjustments for mean age of forest stands were carried out across the region, resulting in a new mapping of aboveground biomass pools based on MODIS satellite data. Yearly maps of newly deforested lands from the Brazilian PRODES (Programa de calculo do desflorestamento da Amazonia ) project were combined with these NASA-CASA biomass predictions to generate seasonal budgets of potential carbon and nitrogen trace gas losses from biomass burning events. Simulations of plant residue and soil carbon decomposition were conducted in the NASA-CASA model during and following deforestation events to track the fate of aboveground biomass pools that were cut and burned each year across the region.

Test bench for PAUCam  

NASA Astrophysics Data System (ADS)

PAU (Physics of the Accelerating Universe), was born as a collaboration project between several Spanish research centers(CIEMAT/IFAE/IEEC-CSIC/UAM) under the Programa Consolider Ingenio 2010. PAU's objective is to make a photometric galaxy survey optimized for Dark Energy studies. The project is building a wide field camera (18 CCDs) with a narrow band filter set, ranging between 4500 and 8500 Angstroms, and wide band filter set. As a previous step, detectors and filters must be tested and certificated, including the quantum efficiency, noise levels and transmittance. To carry out this task, we have prepared two test benches: one of them is at IFAE/IEEC-CSIC (Barcelona) and the other at CIEMAT (Madrid). Our poster describes the test benches' design and present some preliminary results we have obtained with our testing design.

Abundancias químicas de las estrellas CP del grupo HgMn ? Leporis y 53 Tauri. II. Boro, Berilio, Carbono, Magnesio, Aluminio y Silicio  

NASA Astrophysics Data System (ADS)

Se determinan las abundancias químicas de los elementos más livianos presentes en dos estrellas CP del grupo HgMn, ? Lep y 53 Tau, utilizando espectros IUE de alta resolución y técnicas de cálculo de espectros sintéticos. Para el cálculo de las líneas se utiliza la lista mas completa de datos atómicos disponible y el programa SYNTHE. Para el cálculo de la abundancia de un elemento se comparan, para cada imagen, los perfiles observados del mayor número de líneas presentes con los perfiles calculados obtenidos por variación de las abundancias iniciales, reteniendo la abundancia para la cual el acuerdo entre las líneas observadas y calculadas es considerado visualmente el mejor. Los resultados obtenidos son comparados con los estimados por la teoría de la difusión.

2D THD and 3D TEHD analysis of large spindle supported thrust bearings with pins and double layer system used in the three gorges hydroelectric generators  

NASA Astrophysics Data System (ADS)

A 2D THD model and a 3DTEHD model for large spindle supported thrust bearings were set up and used to analyze the lubrication performance of the Three Gorges test thrust beating withpins and double layer system developed by Alstom Power. The finite difference method was employed to solve the THD model, and the thermal-elasticdeformations in the pad and runner were obtained by the finite element software ANSYS11.0. The data transfer between the THD model and ANSYS11.0 was carried out automatically by an interface program.A detailed comparison between the experimental results and numerical predictions by the two different modelsset up in this paper was carried out. Poor agreement has been found between the theoretical results obtained by 2D THD model and experimental data, while 3D TEHD provides fairly good agreement, confirming the importance of thermal effects and thermal-elastic deformations in both pad and runner.

Deforestation and Malaria in M?ncio Lima County, Brazil  

PubMed Central

Malaria is the most prevalent vector-borne disease in the Amazon. We used malaria reports for health districts collected in 2006 by the Programa Nacional de Controle da Malária to determine whether deforestation is associated with malaria incidence in the county (município) of Mâncio Lima, Acre State, Brazil. Cumulative percent deforestation was calculated for the spatial catchment area of each health district by using 60 × 60–meter, resolution-classified imagery. Statistical associations were identified with univariate and multivariate general additive negative binomial models adjusted for spatial effects. Our cross-sectional study shows malaria incidence across health districts in 2006 is positively associated with greater changes in percentage of cumulative deforestation within respective health districts. After adjusting for access to care, health district size, and spatial trends, we show that a 4.3%, or 1 SD, change in deforestation from August 1997 through August 2000 is associated with a 48% increase of malaria incidence.

Amplificadores en bandas para receptores de uso radioastronómicos  

NASA Astrophysics Data System (ADS)

Está en curso de realización en el IAR un cabezal de receptor, en la frecuencia de 3.3 GHz. Este receptor, conjuntamente con los sistemas de procesamientos actuales del IAR y con los futuros proyectos de procesamientos, permitirán las observaciones de las líneas de la molécula de CH, de gran interés astrofísico, y las observaciones en el continuo que complementarán las realizadas en 1420 MHz. En este trabajo, se presentan el diseño de los amplificadores de bajo ruido, que van a conformar las primeras etapas del receptor de 3.3 GHz. El desarrollo de los mismos se realizó teniendo en cuenta que la temperatura del sistema, según consideraciones observacionales, deberá ser de 60oK. Por tal motivo se realizó un diseño de bajo ruido utilizando como elemento activo un HEMT. Tanto los métodos de diseño, como el circuito final, fueron realizados y comprobados con programas de simulación, permitiendo de esta forma obtener el amplificador deseado.

Comportamiento del Helio en estrellas químicamente peculiares  

NASA Astrophysics Data System (ADS)

Las estrellas químicamente peculiares (CP) se caracterizan por tener deficiencias y sobreabundancias de algunos elementos químicos de hasta 106 veces la abundancia solar. Además presentan variaciones en las líneas espectrales. Se piensa que ello se debe a que los campos magnéticos presentes en este tipo de estrellas son principalmente dipolares, con un eje de simetría diferente del eje de rotación. La distribución de los elementos sobreabundantes y deficientes no es homogénea sobre la superficie estelar y las variaciones observadas serían una consecuencia directa de la rotación estelar. Entre los elementos con abundancia anómala se encuentra el Helio, cuyas líneas tienen intensidades que no son consistentes con una abundancia normal, que no puede ser determinada del modo usual, o sea, considerando una atmósfera con composición solar. Con el fin de determinar la abundancia de este elemento, se inició un estudio de estrellas anómalas de Helio, Hew y He strong. Además se determinarán las abundancias de otros elementos anómalos como ser el Si, Cr, Mg, Mn y Fe. Las mismas se determinan del modo tradicional, o sea: a) medida de los anchos equivalentes de las líneas de los distintos elementos analizados; b) adopción de la temperatura efectiva, gravedad y abundancia del Helio; c) cálculo del modelo de atmósfera d) comparación con las observaciones y reinicio de un proceso iterativo hasta lograr un acuerdo entre todos los parámetros analizados. Las observaciones se llevaron a cabo en el Complejo Astronómico El Leoncito. Se observaron setenta y ocho estrellas anómalas de Helio. En este momento se está procediendo a calcular las abundancias correspondientes a los distintos elementos químicos. Para ello se hace uso de los modelos de Kurucz, ATLAS9. Los cálculos NLTE de las líneas de Helio se llevan a cabo con el programa MULTI y se compararán con los realizados con el programa WIDTH9 de Kurucz (LTE), con el objeto de resaltar la importancia de los efectos NLTE.

Projeto do sistema anti-ressonante da fiação dos transdutores para o detector Mario Schenberg  

NASA Astrophysics Data System (ADS)

O detector de ondas gravitacionais Mario Schenberg está sendo projetado e construído pelo grupo Gráviton. Sua construção está ocorrendo no Laboratório de Estado Sólido e Baixas Temperaturas (LESBT) da Universidade de São Paulo, na cidade de São Paulo. Esse detector possui uma massa ressonante esférica de cobre-alumínio, com 65 cm de diâmetro, pesando aproximadamente 1150 Kg, suspensa por um sistema de isolamento vibracional, que se encontra em fase de testes preliminares. A real eficácia desse sistema, entretanto, só poderá ser comprovada quando o detector estiver aparelhado com, pelo menos, um transdutor eletromecânico de altíssima sensibilidade acoplado à massa ressonante. Neste momento, não só este sistema de isolamento vibracional será posto em teste, como o do projeto da fiação que transporta os sinais de microondas até os transdutores e destes para a pré-amplificação. Apesar dessa fiação ter sido projetada para não apresentar nenhum contato com a superfície esférica da antena, de maneira a não haver nenhuma transmissão de ruído vibracional do laboratório para esta, deve-se minimizar o ruído microfônico produzido nessa fiação por oscilações mecânicas, uma vez que ela não utiliza nenhum sistema de isolamento vibracional. Com o intuito de resolver este problema, projetamos uma estrutura, formada por pequenos cilindros conectados por barras, a qual não terá nenhuma ressonância mecânica na faixa de freqüências de interesse para detecção (3000 - 3400 Hz). Desta forma, as vibrações nessa faixa não serão amplificadas. O projeto foi feito usando iterativamente, de maneira a otimizar os resultados obtidos, o programa de elementos finitos Msc/Nastran. Através de simulações feitas neste programa, determinamos os parâmetros geométricos ideais a serem utilizados, os quais proporcionam a maior região espectral de interesse livre de ressonâncias.

Modelagem do vento e da fotosfera de AG Carinae  

NASA Astrophysics Data System (ADS)

A trajetória evolutiva das estrelas de alta massa depende fortemente de suas taxas de perda de massa. Apesar do rápido progresso no estudo destas estrelas, a taxa de perda de massa e outros parâmetros físicos básicos, como a temperatura superficial e a velocidade terminal do vento ainda não estão bem determinados. Isto ocorre devido à presença de ventos irregulares, rápidos e fortes ao redor destas estrelas, tornando a interpretação dos seus espectros uma tarefa difícil. Assim, a modelagem do vento e da fotosfera dessas estrelas está sendo cada vez mais usada para obter tais parâmetros a partir dos espectros. O aumento da taxa de perda de massa durante a fase LBV (Variáveis Luminosas Azuis), comparado com outros tipos de estrelas, tem sido atribuído a instabilidades do tipo S Doradus. Dispomos de uma base de dados espectroscópicos cobrindo 22 anos de observações de AG Carinae, incluindo um ciclo S Doradus completo, com espectros CCD em alta resolução na faixa óptica e infravermelha. Utilizamos o programa desenvolvido por Schmutz (1997) para uma análise preliminar desse ciclo, obtendo a taxa de perda de massa a partir da linha do Ha. Não existe uma correlação clara da taxa de perda de massa com mudanças da temperatura efetiva, do raio da estrela e do fluxo na banda V. A estrela atingiu seu mínimo fotométrico (raio mínimo) em 1990 e o máximo fotométrico (raio máximo) em 1995, enquanto que o fluxo máximo da linha do Ha ocorreu em 1996. Além disso a taxa de perda de massa não segue esse ciclo, contrariamente às idéias correntes. Para fazer um modelo mais realista estamos usando o programa CMFGEN (Hillier & Miller), que trata a fotosfera e o vento estelar de forma consistente, considerando a radiação fora do equilíbrio termodinâmico (NLTE) e com blanketting total de linhas. Simulamos o espectro de AG Carinae em duas épocas extremas do ciclo S Dor para testar os resultados obtidos com o modelo mais simplificado.

Questões mais freqüentes na área de astronomia  

NASA Astrophysics Data System (ADS)

É amplamente reconhecido que as pessoas em geral têm grande fascínio e interesse pela Astronomia. Por outro lado, o conteúdo dessa área incluído no ensino formal está longe de ser abrangente e suficiente para suprir a demanda. Esse interesse permite otimizar a divulgação e o ensino não formal de Astronomia aliando a adequação do conteúdo à expectativa das pessoas. Nesse intuito, nosso trabalho busca mapear que assuntos da Astronomia despertam mais a atenção e o interesse das pessoas e o quanto disso é estimulado pela mídia, que freqüentemente aproveita-se desse interesse de forma sensacionalista, trazendo contribuições positivas e negativas. Para esta avaliação, utilizamos as pesquisas específicas e de caracterização do público que freqüentou o MAst nos anos de 2001 a 2003, pesquisa das matérias de Astronomia veiculadas na mídia escrita da cidade do Rio de Janeiro no mesmo período, além da base de dados do programa Pergunte a um astrônomo, realizado no Observatório Nacional nos anos de 1997 a 1999. Para a análise dos dados, dividimos as perguntas em dez categorias, cada uma com suas subcategorias, tomando como referência as divisões, comissões e grupos de trabalho da IAU. Apresentamos neste trabalho os resultados dessa pesquisa, que incluem, entre outros, a predominância de questões nas categorias Observação do Céu e Sistemas Planetários enquanto nos jornais dominam as notícias de Sistemas Planetários e Espaço & Astronáutica. Outro resultado interessante indicou que as dúvidas de crianças do ensino fundamental se concentram em algumas categorias enquanto as questões de adultos são mais distribuídas por todas as categorias. Os resultados dessa pesquisa serão aplicados diretamente no aperfeiçoamento das atividades do Programa de Observação de Céu, bem como na elaboração de novos projetos e eventos realizados no MAst.

Quality management systems for fruit fly (Diptera: Tephritidae) sterile insect technique  

SciTech Connect

The papers presented in this issue are focused on developing and validating procedures to improve the overall quality of sterile fruit flies for use in area-wide integrated pest management (AW-IPM) programs with a sterile insect technique (SIT) component. The group was coordinated and partially funded by the Joint FAO/IAEA Programme of Nuclear Techniques in Food and Agriculture, International Atomic Energy Agency, Vienna, Austria, under a five-year Coordinated Research Project (CRP) on 'Quality Assurance in Mass-Reared and Released Fruit Flies for Use in SIT Programmes'. Participants in the CRP from 16 countries came from both basic and applied fields of expertise to ensure that appropriate and relevant procedures were developed. A variety of studies was undertaken to develop protocols to assess strain compatibility and to improve colonization procedures and strain management. Specific studies addressed issues related to insect nutrition, irradiation protocols, field dispersal and survival, field cage behavior assessments, and enhancement of mating competitiveness. The main objective was to increase the efficiency of operational fruit fly programs using sterile insects and to reduce their cost. Many of the protocols developed or improved during the CRP will be incorporated into the international quality control manual for sterile tephritid fruit flies, standardizing key components of the production, sterilization, shipment, handling, and release of sterile insects. (author) [Spanish] Los articulos presentados en este numero se enfocan en el desarrollo y la validacion de procedimientos para mejorar la calidad total de moscas de las frutas esteriles para su uso en programas de manejo integrado de plagas en donde la tecnica del insecto esteril (TIE) es uno de los componentes clave. El grupo fue coordinado y parcialmente financiado por la Division Conjunta de Tecnicas Nucleares para la Alimentacion y la Agricultura de la FAO/OIEA, Viena, Austria, por un periodo de cinco anos bajo el proyecto de Investigacion Coordinada (PIC) sobre 'el Aseguramiento de la Calidad de Moscas de las Frutas Criadas y Liberadas para su Uso en Programas de TIE'. Los participantes en el PIC representan 16 paises con experiencia en campos de investigacion basica y aplicada. Para asegurar que los procedimientos desarrollados fueran apropiados y pertinentes, se realizaron una variedad de estudios para el desarrollo de protocolos para evaluar la compatibilidad y para mejorar los procedimientos de colonizacion y manejo de cepas salvajes. Estudios especificos trataron asuntos relacionados con la nutricion de insectos, los protocolos de irradiacion, la dispersion y supervivencia en el campo, evaluacion del comportamiento en jaulas de campo, y el mejoramiento de la competitividad sexual. Los objetivos fundamentales fueron el aumentar la eficiencia y reducir los costos de los programas operacionales de control de moscas de las frutas donde TIE es utilizada. Muchos de los protocolos desarrollados o mejorados durante el PIC seran incorporados en el Manual Internacional de Control de Calidad para Moscas Estriles de la familia Tephritidae, para estandarizar componentes claves como la produccion, esterilizacion, envio, manejo y liberacion de insectos esteriles.

Invertebrate fauna associated with Torpedograss, Panicum repens (Cyperales: Poaceae), in Lake Okeechobee, Florida, and prospects for biological control  

SciTech Connect

Torpedograss, Panicum repens L., is an adventive, rhizomatous grass species that has become an invasive weed of terrestrial, wetland, and aquatic environments in tropical and subtropical regions worldwide. Until recently, strategies for controlling torpedograss in the USA have focused almost exclusively on mechanical and chemical methods, either alone or in combination, with varied results. A survey of the arthropods and nematodes currently associated with the plant in Lake Okeechobee, Florida, was conducted as part of a feasibility study to determine whether torpedograss is an appropriate target for a classical biological control program. Overall, approximately 4,000 arthropods and 400 nematode specimens were collected. Sweep, clipped vegetation, and soil core samples were dominated by representatives of the arthropod orders Hemiptera, Hymenoptera, Diptera, and Acari. Lesion nematodes of the genus Pratylenchus were commonly associated with the roots of torpedograss. None of the organisms collected were torpedograss specialists. Although classical biological control of torpedograss is feasible based on the extent of the infestation, economic losses, resistance to conventional controls, and the report of a potentially host specific natural enemy in India, the botanical position of this grass weed will require a formal risk assessment before proceeding with a classical biological control program. (author) [Spanish] La conota, Panicum repens L., es una especie foranea de pasto que produce rizomas que ha convertido en ser una maleza invasora de ambientes terrestres, pantanosos y acuaticos en regiones tropicales y subtropicales en todo el mundo. Hasta hace un tiempo reciente, las estrategias para controlar conota en los EEUU eran enfocadas casi exclusivamente en los metodos mecanicos y quimicos, solos o en combinacion, con resultados variables. Un muestreo de los artropodos y nematodos asociados corrientemente con esta planta en el Lago de Okeechobee, Florida, fue realizado como parte de un estudio de factibilidad para determinar si conota es una candidata apropiada para un programa de control biologico clasico. En general, especimenes de aproximadamente unos 4,000 artropodos y unos 400 nematodos fueron recolectados. Muestras recolectadas pasando una red sobre vegetacion mezclada, cortando la vegetacion y tomando centros del suelo fueron dominados por representantes de artropodos de los ordenes de Hemiptera, Hymenoptera, Diptera, y Acari. Nematodos en el genero Pratylenchus, que causan lesiones sobre tejido, fueron asociados regularmente con las raices de conota. Ninguno de los organismos recolectados eran especialistas sobre conota. Aunque el control biologico clasico de la conota es factible basado sobre la magnitud de la infestacion, las perdidas economicas, la resistencia hacia los metodos de control convencionales y el informe en la India de un posible enemigo natural especifico a esta planta, la posicion botanica de este pasto maleza requiere una evaluacion de riesgo economico formal antes de continuar con un programa de control biologico clasico.

Source apportionment to PM10 and PM2.5 at multiple sites in the Bay of Gibraltar (S Spain) by PMF: estimate of shipping emission  

NASA Astrophysics Data System (ADS)

The recognized adverse health effect of the PM10 and PM2.5 particles leads to an increasing demand of a more efficient control of pollutant emissions especially in industrial and/or urban sites. The degree with which the control of the emissions can be accomplished depends on the identification of the pollutant sources and the estimation of their contribution. The chemical speciation of ambient PM coupled with receptor modelling can be considered as a powerful tool to estimate origin of the sources and their contribution to the PM10 and PM2.5 fractions. This work aims to evaluate the effect on air quality of the anthropogenic activities performed in one of the most important industrial estates of Southern Spain located in the Bay of Gibraltar. The area under study is characterized by the presence of metallurgy industries and oil refineries around which four urban agglomerates are located, namely: Los Barrios (36°11'7.39"N, 5°29'33.89"O), La Linea (36° 9'40.24"N, 5°20'53.72"O), Algeciras (36°7'47.21"N, 5°26'51.71"O) y Puente Mayorga (36°10'54.60"N, 5°23'8.32"O). Traffic is consequently another important source of pollutants in the considered area together with an intense shipping activity. The estimation of the pollutant sources and their contribution was obtained by applying the Positive Matrix Factorization (PMF) model to the PM10 and PM2.5 levels and chemical speciation data simultaneously obtained in the four urban agglomerates during a period of 4 years (March 2003 - December 2007). Given the small size of the area under study, the PM data collected in all the four stations was simultaneously introduced within the PMF model. This procedure allowed the PMF to use a higher number of data rather than using the 4 database separately, thus improving the performances of the model. Following this procedure a total of 567 and 341 samples for the PM10 and PM2.5 fractions respectively were introduced within the PMF. Moreover, before running the model, a detailed inspection of the database was performed in order to look for the possible presence of weaker data such as contaminated data, below detection limit data, missing data etc. This procedure is important in order to improve the performances of the model, reducing the error associated with the calculated sources contributions. In the present work seven sources were obtained in both PM10 and PM2.5 fractions, namely: crustal (traced by Al, Ca, K, Ti, Fe, Rb, Sr), marine (traced by Na, Cl, Mg), industrial (Cr, Mn, P, Zn, Fe, As, Ni, Pb), oil combustion (traced by V, Ni y La from both oil refinery and shipping emissions), traffic (OC+EC, Cu, Sn, Sb), secondary sulphate (SO4= and NH4+), ammonium nitrate in PM2.5 (traced by NO3- and NH4+) and sodium nitrate in PM10 (Na and NO3-). In PM10 fraction the main contributing sources in all stations were secondary sulphate (19-22% of PM10 mass), sodium nitrate (15-21%) and crustal (14-23%) followed by traffic (10-21%), marine (10-17%), oil combustion (6-9%) and industrial (1-5%). The main contributing sources in PM2.5 were regional sulphate (28-34%), ammonium nitrate and traffic (10-15%), crustal (8-18%), oil combustion and marine (8-10%), and industrial (2-7%). Further information on source contributions and locations were obtained by coupling PMF with wind direction data which show two privileged mean wind directions in the considered area: SSE-ESE (75% of occurrence) and W-NW (80% of occurrence). In this work wind data was used to separately evaluate the contributions from shipping and oil refinery which were not separated by the PMF model mainly as a consequence of the similarity in the fingerprints of these two sources.

[The registered nurse and the battle against tuberculosis in Brazil: 1961-1966].  

PubMed

The objective of this study was to describe the circumstances that promoted the implementation of the new Program for Action Against Tuberculosis in Brazil (Programa de Ação na Luta contra a Tuberculose no Brasil) and discuss the strategies used by registered nurses from the Santa Maria State Hospital, Guanabara State, to adjust nursing care to the new program against tuberculosis. This was performed through document research, interviews, and statements from nurses working at the time of the reorganization. Documents were analyzed based on the concepts of habitus, field, and symbolic power by Pierre Bourdieu, and included written and oral documents as well as secondary sources. The reorganization of the nursing service was performed under the leadership of a nurse whose symbolic capital assigned power and prestige to implement the necessary changes. It is concluded that the work of that nurse made it possible to implement the new program and contributed to establishing the position and importance of the registered nurse in providing care to individuals with tuberculosis, for prevention and cure.

Incorporando a variabilidade no processo de identifica??o do modelo de m?ximo global no Grade of Membership (GoM): considera??es metodol?gicas  

PubMed Central

A disponibilidade de bases de dados cada vez mais complexas e multidimensionais é um dos principais motivadores para o aumento do número de estudos que utilizam análises multivariadas baseadas em lógica de conjuntos nebulosos. Apesar da disseminação do método Grade of Membership nos trabalhos empíricos brasileiros da área de ciências sociais e saúde, questões relativas à identificabilidade e estabilidade dos parâmetros finais estimados pelo programa GoM 3.4 não foram suficientemente aprofundadas. Dada a relevância de se obterem parâmetros únicos e estáveis, Guedes et al. (2010) propuseram um procedimento empírico para localizar um modelo de máximo global (MG) com parâmetros estáveis. Entretanto, seu localizador de MG não incorpora qualquer medida de variabilidade. Neste artigo, tal limitação é contornada por meio da utilização de uma estatística de ponderação – Máximo Global Ponderado (MGP) – semelhante ao coeficiente de variação. Esse indicador busca não penalizar de forma desproporcional situações nas quais os desvios médios, apesar de diferentes de zero, são muito pequenos. Apresentam-se evidências de que o localizador MGP reduz a distância do modelo identificado à real estrutura latente dos dados em análise, quando comparados ao modelo identificado pelo localizador não ponderado, MG.

[Cervical intraepithelial lesions in adolescents: cytological findings from 1999 to 2005 in Rio de Janeiro, Brazil].  

PubMed

The prevalence of cervical intraepithelial neoplasias has increased in adolescents, probably due to the decrease in age at first intercourse and increase in the number of sexual partners. Our objective was to analyze the trends in cervical intraepithelial lesions in adolescents in the city of Rio de Janeiro, Brazil. We thus conducted a retrospective analysis of 1,516,407 Pap smears performed at public health units from 1999 to 2005. During the study period, the distribution and temporal trend in cytological abnormalities was compared between adolescent and adult women. There were more atypical smears in adolescents, mainly low-grade lesions. In adolescents, cervical abnormalities doubled during this period, from 6.4% to 12.4%, while in adult women it increased from 4.5% to 6.7%. Statistical analysis showed a tendency towards a linear increase in frequency of abnormal Pap smears in both adolescents and adults (0.008% and 0.003%, respectively). Based on this and other studies, we recommend including adolescents in the target population of the Brazilian cervical cancer screening program ("Programa Viva Mulher"). PMID:19082279

Implementation of several mathematical algorithms to breast tissue density classification  

NASA Astrophysics Data System (ADS)

The accuracy of mammographic abnormality detection methods is strongly dependent on breast tissue characteristics, where a dense breast tissue can hide lesions causing cancer to be detected at later stages. In addition, breast tissue density is widely accepted to be an important risk indicator for the development of breast cancer. This paper presents the implementation and the performance of different mathematical algorithms designed to standardize the categorization of mammographic images, according to the American College of Radiology classifications. These mathematical techniques are based on intrinsic properties calculations and on comparison with an ideal homogeneous image (joint entropy, mutual information, normalized cross correlation and index Q) as categorization parameters. The algorithms evaluation was performed on 100 cases of the mammographic data sets provided by the Ministerio de Salud de la Provincia de Córdoba, Argentina—Programa de Prevención del Cáncer de Mama (Department of Public Health, Córdoba, Argentina, Breast Cancer Prevention Program). The obtained breast classifications were compared with the expert medical diagnostics, showing a good performance. The implemented algorithms revealed a high potentiality to classify breasts into tissue density categories.

Availability, prices and affordability of the World Health Organization's essential medicines for children in Guatemala  

PubMed Central

Background Several World Health Organization (WHO) initiatives aim to improve the accessibility of safe and effective medicines for children. A first step in achieving this goal is to obtain a baseline measure of access to essential medicines. The objective of this project was to measure the availability, prices, and affordability of children’s medicines in Guatemala. Methods An adaption of the standardized methodology developed by the World Health Organization and Health Action International (HAI) was used to conduct a cross sectional survey to collect data on availability and final patient prices of medicines in public and private sector medicine outlets during April and May of 2010. Results A subset of the public sector, Programa de Accesibilidad a los Medicamentos (PROAM), had the lowest average availability (25%) compared to the private sector (35%). In the private sector, highest and lowest priced medicines were 22.7 and 10.7 times more expensive than their international reference price comparison. Treatments were generally unaffordable, costing as much as 15 days wages for a course of ceftriaxone. Conclusions Analysis of the procurement, supply and distribution of specific medicines is needed to determine reasons for lack of availability. Improvements to accessibility could be made by developing an essential medicines list for children and including these medicines in national purchasing lists.

International activities of Sandia's Design Assistance Center. Mexico enlists Sandia to help bring solar electricity to remote villiages  

SciTech Connect

Sandia has been working with various organizations in Mexico for more than a year to help support Mexican projects currently underway. These projects use renewable energy to bring electricity to rural Mexican communities needing power to improve their economic and social well-being. Under the National Solidarity Program, la Programa Nacional de Solidaridad (PRONSAL), a program for rural development, the government of Mexico has been using renewable energy technologies in rural electrification and development projects. Electrification is one of its major components, and renewable energy systems have been used to electrify a number of rural communities. The lessons and examples this program provides will be able to influence the rural electrification policies of other developing countries, particularly in Latin America. The US Department of Energy and US Agency for International Development are supporting Mexico's renewables program activities through a working-level cooperative program between the US and Mexico called PROCER. Specific areas of cooperation include information exchange on technical and commercial products, training, and technical assistance, resource assessment, market development, and work related to project financing. Sandia's role in PROCER is to provide technical oversight to the program on behalf of DOE/OSEC, CORECT, and AID/Mexico.

The Future of Vertical Lift: initial insights for aircraft capability and medical planning.  

PubMed

The U.S. Army continues to evaluate capabilities associated with the Future of Vertical Lift (FVL) program-a futures program (with a time horizon of 15 years and beyond) intended to replace the current helicopter fleet. As part of the FVL study, we investigated required capabilities for future aeromedical evacuation platforms. This study presents two significant capability findings associated with the future aeromedical evacuation platform and one doctrinal finding associated with medical planning for future brigade operations. The three results follow: (1) Given simplifying assumptions and constraints for a scenario where a future brigade is operating in a 300 x 300 km2, the zero-risk aircraft ground speed required for the FVL platform is 350 nautical miles per hour (knots); (2) Given these same assumptions and constraints with the future brigade projecting power in a circle of radius 150 km, the zero-risk ground speed required for the FVL platform is 260 knots; and (3) Given uncertain casualty locations associated with future brigade stability and support operations, colocating aeromedical evacuation assets and surgical elements mathematically optimizes the 60-minute set covering problem.

Controle orbital de satélites artificiais com propulsão e uso de gravidade lunar  

NASA Astrophysics Data System (ADS)

A redução do custo de combustível de uma manobra é atualmente a grande prioridade de todos os programas espaciais existentes no mundo. As manobras assistidas pela gravidade são uma ótima forma de se contornar o problema pois proporcionam economias com vasto impacto no custo final da missão. Neste trabalho é feito um estudo particular do controle orbital de um satélite artificial da Terra usando a gravidade da Lua. O objetivo é estudar uma técnica econômica para uma mudança de plano de um satélite que está em órbita em volta da Terra. A idéia principal desta abordagem é enviar primeiramente o veículo espacial em direção à Lua usando uma manobra mono-impulsiva para que assim o campo gravitacional da Lua possa fazer a mudança de plano desejada (sem custo de combustível) e só então retornar o veículo aos valores iniciais de semi-eixo e excentricidade usando uma manobra bi-impulsiva tipo Hohmann. Para tanto, é assumido que a espaçonave inicia em uma órbita circular coplanar à órbita da lua em torno da Terra e a meta é colocá-la em uma órbita similar que difere da órbita inicial somente pela inclinação. São usadas equações analíticas baseadas na abordagem Patched Conics para se calcular a variação na velocidade, momento angular, energia e inclinação do veículo espacial que realiza esta manobra. Várias simulações são feitas para se avaliar as economias de combustível envolvidas.

Risk-adapted treatment of acute promyelocytic leukemia with all-trans retinoic acid and anthracycline monochemotherapy: long-term outcome of the LPA 99 multicenter study by the PETHEMA Group.  

PubMed

A previous report of the Programa de Estudio y Tratamiento de las Hemopatías Malignas (PETHEMA) Group showed that a risk-adapted strategy combining all-trans retinoic acid (ATRA) and anthracycline monochemotherapy for induction and consolidation in newly diagnosed acute promyelocytic leukemia results in an improved outcome. Here we analyze treatment outcome of an enlarged series of patients who have been followed up for a median of 65 months. From November 1999 through July 2005 (LPA99 trial), 560 patients received induction therapy with ATRA plus idarubicin. Patients achieving complete remission received 3 courses of consolidation followed by maintenance with ATRA and low-dose chemotherapy. The 5-year cumulative incidence of relapse and disease-free survival were 11% and 84%, respectively. These results compare favorably with those obtained in the previous LPA96 study (P = .019 and P = .04, respectively). This updated analysis confirms the high antileukemic efficacy, low toxicity, and high degree of compliance of a risk-adapted strategy combining ATRA and anthracycline monochemotherapy for consolidation therapy.

Causes and prognostic factors of remission induction failure in patients with acute promyelocytic leukemia treated with all-trans retinoic acid and idarubicin.  

PubMed

An understanding of the prognostic factors associated with the various forms of induction mortality in patients with acute promyelocytic leukemia (APL) has remained remarkably limited. This study reports the incidence, time of occurrence, and prognostic factors of the major categories of induction failure in a series of 732 patients of all ages (range, 2-83 years) with newly diagnosed APL who received all-trans retinoic acid (ATRA) plus idarubicin as induction therapy in 2 consecutive studies of the Programa de Estudio y Tratamiento de las Hemopatias Malignas (PETHEMA) Group. Complete remission was attained in 666 patients (91%). All the 66 induction failures were due to induction death. Hemorrhage was the most common cause of induction death (5%), followed by infection (2.3%) and differentiation syndrome (1.4%). Multivariate analysis identified specific and distinct pretreatment characteristics to correlate with an increased risk of death caused by hemorrhage (abnormal creatinine level, increased peripheral blast counts, and presence of coagulopathy), infection (age>60 years, male sex, and fever at presentation), and differentiation syndrome (Eastern Cooperative Oncology Group [ECOG] score>1 and low albumin levels), respectively. These data furnish clinically relevant information that might be useful for designing more appropriately risk-adapted treatment protocols aimed at reducing the considerable problem of induction mortality in APL.

Differentiation syndrome in patients with acute promyelocytic leukemia treated with all-trans retinoic acid and anthracycline chemotherapy: characteristics, outcome, and prognostic factors.  

PubMed

Differentiation syndrome (DS) can be a life-threatening complication in patients with acute promyelocytic leukemia (APL) undergoing induction therapy with all-trans retinoic acid (ATRA). Detailed knowledge about DS has remained limited. We present an analysis of the incidence, characteristics, prognostic factors, and outcome of 739 APL patients treated with ATRA plus idarubicin in 2 consecutive trials (Programa Español de Tratamientos en Hematología [PETHEMA] LPA96 and LPA99). Overall, 183 patients (24.8%) experienced DS, 93 with a severe form (12.6%) and 90 with a moderate form (12.2%). Severe but not moderate DS was associated with an increase in mortality. A bimodal incidence of DS was observed, with peaks occurring in the first and third weeks after the start of ATRA therapy. A multivariate analysis indicated that a WBC count greater than 5 x 10(9)/L and an abnormal serum creatinine level correlated with an increased risk of developing severe DS. Patients receiving systematic prednisone prophylaxis (LPA99 trial) in contrast to those receiving selective prophylaxis with dexamethasone (LPA96 trial) had a lower incidence of severe DS. Patients developing severe DS showed a reduced 7-year relapse-free survival in the LPA96 trial (60% vs 85%, P = .003), but this difference was not apparent in the LPA99 trial (86% vs 88%).

Detección automática de NEOs en imágenes CCD utilizando la transformada de Hough  

NASA Astrophysics Data System (ADS)

El interés y la dedicación por los objetos que se acercan a la órbita de la Tierra (NEOs) ha aumentado considerablemente en los últimos años, tanto que se han iniciado varias campañas de búsqueda sistemática para aumentar la población identificada de éstos. El uso de placas fotográficas e identificación visual está siendo sustituído, progresivamente, por el uso de cámaras CCD y paquetes de detección automática de los objetos en las imágenes digitales. Una parte muy importante para la implementación exitosa de un programa automatizado de detección de este tipo es el desarrollo de algoritmos capaces de identificar objetos de baja relación señal-ruido y con requerimientos computacionales no elevados. En el presente trabajo proponemos la utilización de la transformada de Hough (utilizada en algunas áreas de visión artificial) para detectar automáticamente trazas, aproximadamente rectilíneas y de baja relación señal-ruido, en imágenes CCD. Desarrollamos una primera implementación de un algoritmo basado en ésta y lo probamos con una serie de imágenes reales conteniendo trazas con picos de señales de entre ~1 ? y ~3 ? por encima del nivel del ruido de fondo. El algoritmo detecta, sin inconvenientes, la mayoría de los casos y en tiempos razonablemente adecuados.

Estereotipos Sexuales y su Relaci?n con Conductas Sexuales Riesgosas1,2,3  

PubMed Central

Resumen Los estereotipos sexuales son creencias generalmente aceptadas y poco cuestionadas que podrían contribuir a cómo los hombres y las mujeres debemos expresar nuestra sexualidad. Los objetivos de este estudio eran identificar cuántos hombres y mujeres heterosexuales en Puerto Rico endosaban ciertos estereotipos acerca de la sexualidad masculina y femenina y explorar la relación entre el endoso de estos estereotipos sexuales y las actitudes hacia el condón masculino y su uso en relaciones sexuales vaginales Llevamos a cabo un estudio descriptivo-correlacional mediante el cual le administramos dos escalas, una sobre sexualidad masculina y otra sobre sexualidad femenina a un grupo de 429 personas heterosexuales. Encontramos que los hombres endosaron estereotipos sexuales masculinos y femeninos más que las mujeres y que estos tienden a tener una visión más conservadora respecto a la sexualidad femenina que la que tienen sobre su propia sexualidad. Las mujeres, por otra parte, tienden a ver su propia sexualidad y la sexualidad masculina en términos menos estereotipados y más equitativos. También encontramos que a mayor endoso de creencias tradicionales sobre la sexualidad masculina y femenina, peor la actitud hacia el uso del condón masculino. Sin embargo, el endosar estereotipos sexuales masculinos y/o femeninos no se relacionó con el uso del condón. Estos hallazgos contradicen la literatura que sugiere que estos estereotipos sexuales y de género resultan en conductas sexuales de alto riesgo, lo cual tiene implicaciones importantes para el desarrollo e implementación de programas de prevención.

Smoldering multiple myeloma requiring treatment: time for a new definition?  

PubMed

Smoldering multiple myeloma (SMM) bridges the gap between monoclonal gammopathy of undetermined significance (a mostly premalignant disorder) and active multiple myeloma (MM). Until recently, no interventional study in patients with SMM showed improved overall survival (OS) with therapy as compared with observation. A report from the PETHEMA-GEM (Programa Español de Tratamientos en Hematologica) group described both fewer myeloma-related events and better OS among patients with high-risk SMM who were treated with lenalidomide and dexamethasone. This unique study prompted us to review current knowledge about SMM and address the following questions: (1) Are there patients currently defined as SMM who should be treated routinely? (2) Should the definitions of SMM and MM be reconsidered? (3) Has the time come when not treating is more dangerous than treating? (4) Could unintended medical harm result from overzealous intervention? Our conclusion is that those patients with the highest-risk SMM (extreme bone marrow plasmacytosis, extremely abnormal serum immunoglobulin free light chain ratio, and multiple bone lesions detected only by modern imaging) should be reclassified as active MM so that they can receive MM-appropriate therapy and the paradigm of careful observation for patients with SMM can be preserved.

Precisión de las velocidades radiales obtenidas con el REOSC  

NASA Astrophysics Data System (ADS)

Complementando una línea de trabajo iniciada con anterioridad discutimos la estabilidad del espectrógrafo REOSC de CASLEO en DC para la medición de velocidades radiales en base al análisis de observaciones realizadas en enero y abril de 1997. En esas oportunidades obtuvimos 26 espectros de estrellas patrones y 27 espectros de 3 estrellas usadas como estrellas de referencia en nuestro programa de cúmulos abiertos. Además tomamos 26 espectros de crepúsculo con el telescopio en posiciones cubriendo el rango H=-4,+4 y ? =-90,+30. Mediante correlaciones cruzadas derivamos la velocidad de 19 órdenes en cada uno de estos espectros. En base a un análisis estadístico de los datos obtenidos discutimos la contribución de los distintos factores que afectan a la dispersión de lectura observada. En particular, la flexión del instrumento no introduciría errores significativos cuando se observa con masas de aire menores que 2.0. La dispersión de los valores de velocidad medidos para espectros de alta relación S/N de una misma estrella resultó del orden de 0.5 km/s. La comparación con los valores de velocidad publicados por distintos autores para las estrellas patrones no permite distinguir ninguna diferencia sistemática apreciable de las velocidades de CASLEO, siendo la media cuadrática de los residuos del orden de 1.0 km/s.

Groundwater demand management at local scale in rural areas of India: a strategy to ensure water well sustainability based on aquifer diffusivity and community participation  

NASA Astrophysics Data System (ADS)

Watershed development programmes provide an opportunity for sustainable management strategies, although currently, they remain largely `supply-side' mechanisms of water resources development. Hydrogeological conditions, community participation and status of groundwater usage are important in evolving strategies on `demand-side' groundwater management. Neemkheda aquifer is a typical low-storage, low-hydraulic conductivity aquifer from a watershed in the dryland regions of Madhya Pradesh State of central India. A shallow unconfined aquifer, it consists of an upper coarse, calcareous sandstone unit underlain by a fine-grained sandstone unit. A `well commune' of seven wells is poised to test the concept of joint groundwater management, wherein wells are mechanisms of tapping a common water source, the Neemkheda aquifer. The strategy for systematic groundwater management in the Neemkheda well commune is based upon the relationship between Transmissivity (T) and Storage coefficient (S), i.e. aquifer diffusivity, and its variation within the aquifer. Wells within a high diffusivity domain tend to dewater more quickly than wells within a low diffusivity domain. A well-use schedule during the dry season, based upon aquifer diffusivity forms the basis of the groundwater management concept. The distribution of local aquifer diffusivities governs the relationship between local and regional aquifer depletion times and forms the basis of the groundwater management exercise being proposed for the Neemkheda aquifer. Los programas de desarrollo de una cuenca hídrica son una oportunidad para el uso de estrategias de gestión sostenible, aunque hoy en día estas siguen siendo principalmente mecanismos para el desarrollo de recursos hídricos con énfasis en la ``oferta''. Las condiciones hidrogeológicas, la participación comunitaria y la condición de utilización del agua subterránea, son importantes en el desarrollo de estrategias para la gestión del agua subterránea, desde el punto de vista de la ``demanda''. El acuífero de Neemkheda es un acuífero típico de almacenamiento bajo y conductividad hidráulica baja, perteneciente a una cuenca hídrica ubicada en las regiones secas del Estado de Madhya Pradesh, en la parte central de India. Un acuífero de tipo libre, somero, formado por una unidad superior de arenisca calcárea de grano grueso, subyacida por una unidad de arenisca de grano fino. Un campo de pozos comunitario compuesto por siete pozos, pone a prueba el concepto de gestión conjunta del agua subterránea, dentro del cual los pozos son mecanismos para usar una fuente de agua común: El acuífero de Neemkheda. La estrategia usada para la gestión sistemática del agua subterránea, en el campo de pozos comunitario de Neemkheda, se basa en la relación existente entre Transmisividad (T) y Coeficiente de Almacenamiento (S), es decir en la Difusividad del Acuífero y en su variación observada dentro del mismo acuífero. Los pozos cuya difusividad esta dentro de un rango alto, tienden a experimentar un descenso en su nivel mas rápidamente que aquellos pozos con una difusividad baja. El concepto de gestión de agua subterránea se basa en un programa especial de operación para cada pozo durante la estación seca, el cual a su vez se basa en la difusividad del acuífero. La distribución de difusividades locales del acuífero rige las relaciones entre las épocas de descensos de nivel en el acuífero a escala regional y local, y además constituyen la base del ejercicio de la gestión del agua subterránea que se esta proponiendo para el acuífero de Neemkheda. Les programmes de développement des bassins versants offrent une occasion de développer des stratégies pour une gestion durable, bien qu' à présent elles restent en grande mesure `le terme source' dans le mécanisme de développement de la ressource en eau. Les conditions hydrogéologiques, la participation de la communauté et l'usage des eaux souterraines sont importants pour le `terme demande' dans les stratégies de gestion des eaux souterraines.

Combined Use of Polar and Geostationary Satellite Sensors For Aerosol Characterization Over The Ocean  

NASA Astrophysics Data System (ADS)

Aerosol particles play an important role in the Earth's climate due to their direct and indirect interaction with the atmosphere. Monitoring of the optical properties of atmospheric aerosol is thus crucial for a radiative forcing quantification at the lo- cal, regional and global scales. Ground-based measurements provide accurate aerosol properties. However, given the strong spatial and temporal variability of tropospheric aerosols ground measurements cannot cover the global scale. On the other hand, satellite-based algorithms for aerosol retrievals presently do not match the accuracy of ground-based results. Most satellite algorithms are based on a single sensor, thus often suffering from specific limitations (poor spatial or spectral resolution, long re- visitation time, poor cloud mask). A method to exploit the synergy between the polar orbiting Global Ozone Monitoring Experiment (GOME) onboard ERS-2 and the METEOSAT geostationary system was proposed (Costa et al., 2001), aiming at increasing the accuracy of the aerosol charac- terization and monitoring of the optical thickness. A validation of the algorithm is done by comparing satellite retrievals with results obtained via independent space-time co- located ground-based measurements from AERONET (Aerosol Robotic NETwork) and from other state of the art algorithms that make use of satellite measurements such as the MODIS official aerosol product. Results of the ongoing validation are pre- sented for relevant transport events of desert dust and biomass burning aerosol over the Atlantic and Indian Oceans during year 2000.

Operational forecasting of daily temperatures in the Valencia Region. Part I: maximum temperatures in summer.  

NASA Astrophysics Data System (ADS)

Extreme temperature events have a great impact on human society. Knowledge of summer maximum temperatures is very useful for both the general public and organisations whose workers have to operate in the open, e.g. railways, roadways, tourism, etc. Moreover, summer maximum daily temperatures are considered a parameter of interest and concern since persistent heat-waves can affect areas as diverse as public health, energy consumption, etc. Thus, an accurate forecasting of these temperatures could help to predict heat-wave conditions and permit the implementation of strategies aimed at minimizing the negative effects that high temperatures have on human health. The aim of this work is to evaluate the skill of the RAMS model in determining daily maximum temperatures during summer over the Valencia Region. For this, we have used the real-time configuration of this model currently running at the CEAM Foundation. To carry out the model verification process, we have analysed not only the global behaviour of the model for the whole Valencia Region, but also its behaviour for the individual stations distributed within this area. The study has been performed for the summer forecast period of 1 June - 30 September, 2007. The results obtained are encouraging and indicate a good agreement between the observed and simulated maximum temperatures. Moreover, the model captures quite well the temperatures in the extreme heat episodes. Acknowledgement.

Operational forecasting of daily temperatures in the Valencia Region. Part II: minimum temperatures in winter.  

NASA Astrophysics Data System (ADS)

Extreme temperature events have a great impact on human society. Knowledge of minimum temperatures during winter is very useful for both the general public and organisations whose workers have to operate in the open, e.g. railways, roadways, tourism, etc. Moreover, winter minimum temperatures are considered a parameter of interest and concern since persistent cold-waves can affect areas as diverse as public health, energy consumption, etc. Thus, an accurate forecasting of these temperatures could help to predict cold-wave conditions and permit the implementation of strategies aimed at minimizing the negative effects that low temperatures have on human health. The aim of this work is to evaluate the skill of the RAMS model in determining daily minimum temperatures during winter over the Valencia Region. For this, we have used the real-time configuration of this model currently running at the CEAM Foundation. To carry out the model verification process, we have analysed not only the global behaviour of the model for the whole Valencia Region, but also its behaviour for the individual stations distributed within this area. The study has been performed for the winter forecast period from 1 December 2007 - 31 March 2008. The results obtained are encouraging and indicate a good agreement between the observed and simulated minimum temperatures.

Onshore wind energy potential over Iberia: present and future projections  

NASA Astrophysics Data System (ADS)

Onshore grid-connected wind power generation has been explored for more than three decades in the Iberian Peninsula. Further, increasing attention has been devoted to renewable energy sources in a climate change context. While advantages of wind energy are widely recognized, its distribution is not spatially homogeneous and not uniform throughout the year. Hence, understanding these spatial-temporal distributions is critical in power system planning. The present study aims at assessing the potential power output estimated from 10 m wind components simulated by a regional climate model (CCLM), driven by ERA40 reanalysis. Datasets are available on a grid with a high spatial resolution (approximately 20 km) and over a 40-yr period (1961-2000). Furthermore, several target sites, located in areas with high installed wind generation capacity, are selected for local-to-regional scale assessments. The results show that potential wind power is higher over northern Iberia, mostly in Cantabria and Galicia, while Andalucía and Cataluña record the lowest values. With respect to the intra-annual variability, summer is by far the season with the lowest potential energy outputs. Furthermore, the inter-annual variability reveals an overall downward long-term trend over the 40-yr period, particularly in the winter time series. A CCLM transient experiment, forced by the SRES A1B emission scenario, is also discussed for a future period (2041-2070), after a model validation/calibration process (bias corrections). Significant changes in the wind power potential are projected for the future throughout Iberia, but their magnitude largely depends on the locations. This work was partially supported by FEDER (Fundo Europeu de Desenvolvimento Regional) funds through the COMPETE (Programa Operacional Factores de Competitividade) and by national funds through FCT (Fundação para a Ciência e a Tecnologia, Portugal) under project STORMEx FCOMP-01-0124-FEDER- 019524 (PTDC/AAC-CLI/121339/2010).

Physical activity, psychosocial and perceived environmental factors in adolescents from Northeast Brazil.  

PubMed

The aim of this study was to evaluate the association between levels of physical activity, psychosocial and perceived environmental factors in adolescents from Northeastern Brazil. A cross-sectional epidemiologic study was conducted with 2,859 adolescents enrolled in secondary schools (57.8% females; mean = 16.5 years; SD = 1.2) in the city of João Pessoa, Paraíba State, Brazil. The following physical activity correlates were measured: attitude, self-efficacy, social support from friends and parents, and perceived environmental characteristics. Physical activity was measured using a questionnaire. Multivariable ordinal logistic regression with proportional odds model analysis showed that the following factors are positively related to physical activity levels in adolescents: attitude, self-efficacy, as well as social support from parents and friends. Physical activity intervention programs should increase self-efficacy and social support from parents and friends, as well as a positive attitude toward physical activity.Este estudo analisou a associação do nível de atividade física com fatores psicossociais e ambientais em adolescentes do Nordeste do Brasil. Estudo epidemiológico transversal desenvolvido com 2.859 adolescentes (57,8% do sexo feminino, média de idade: 16,5 anos; DP = 1,2) no Município de João Pessoa, Paraíba, Brasil. Os seguintes fatores associados à atividade física foram mensurados: atitude, autoeficácia, apoio social dos pais e amigos e características do ambiente percebido. O nível de atividade física foi mensurado por questionário. Os resultados da análise multivariável por regressão logística ordinal, com modelo de odds proporcionais, identificaram os seguintes fatores positivamente associados ao nível de atividade física dos adolescentes: atitude, percepção de autoeficácia, apoio social dos pais e amigos. Programas de promoção da atividade física devem desenvolver ações para aumentar a autoeficácia dos adolescentes e o apoio social fornecido pelos pais e amigos, bem como desenvolver e reforçar atitudes positivas em relação à atividade física.

The Tutorial Education Program on the Formation of the New Milenium's Meteorologist: 20 Years of Project Experience at Universidade Federal de Pelotas - Brazil  

NASA Astrophysics Data System (ADS)

The Programa de Educação Tutorial (Tutorial Education Program), also known as "PET", has the objective to finance students with potential, encouraging and providing extracurricular activities in order to promote the integration with the academic market and the development of study programs in graduate school, preparing a professional that in the future will operate in a global market, transforming and fighting for the professional interests of their class. The design of the program dates back to 1970 and is based on the model of learning and guidance to form the student. The groups are composed gradually, through an annual selection. The deployment and implementation of the groups consider the inclusion of new members in different stages of their school program, working in an integrated manner. To apply, students must submit satisfactory academic performance, without failures on any course and commit to devote a minimum of twenty hours per week to the program activities. Deployed at Universidade Federal de Pelotas - Brazil, in 1991, the group has contributed to the training of students of Meteorology through the concept of teaching-research-extension activities. We believe that PET has been of utmost importance in the training of the new millennium's professional, given that the objectives of this program seek to provide an excellent level of academic training to undergraduates, encouraging their entry into the graduate studies; stimulating the improvement of the quality of teaching degree through the development of new practices and teaching experience; multiplying the activities developed by scholars and increase their interactions with program's faculty and other students of the institution. With the highly competitive market requiring specialized professionals, the high investment in students with potential can be reversed for the benefit of the profession.

Identificação de variáveis cataclísmicas eruptivas na direção do bojo galáctico e Nuvens de Magalhães usando dados do OGLE  

NASA Astrophysics Data System (ADS)

Na década de 90 iniciaram-se vários programas para a pesquisa de matéria escura na Galáxia usando o efeito de microlentes gravitacionais. Entre os projetos mais bem conhecidos podemos mencionar o OGLE (Optical Gravitational Lensing Experiment) e o MACHO (MAssive Compact Halo Objects). A estratégia usada por eles consiste em fazer fotometria de banda larga (normalmente B, R e I) de um grande número de estrelas (dezenas de milhões) tão freqüentemente quanto possí vel e por longos perí odos de tempo (anos). Uma tal sistemática de observação, além de descobrir inúmeras lentes gravitacionais, é também muito apropriada para a descoberta de estrelas variáveis. De fato, inúmeras novas variáveis de vários tipos foram descobertas como subproduto. Exemplos podem ser encontrados nos endereços http://bulge.princeton.edu/~ogle/ e http://wwwmacho.mcmaster.ca/. As variáveis cataclí smicas eruptivas (novas clássicas, novas recorrentes e novas anãs) são objetos que apresentam variabilidade de grande amplitude com escalas de tempo de dias a centenas de dias e, por esta razão, devem ter sido detectadas em grande número nestes "surveys". Para testar esta possibilidade nós procuramos nos dados do OGLE por tais sistemas e o presente trabalho mostra os resultados desta pesquisa. Os objetos foram selecionados entre as variáveis detectadas usando a amplitude de variação de brilho como critério principal. Este critério forneceu 13756 objetos, sendo 2169 na direção da Grande Nuvem de Magalhães, 1162 na direção da Pequena Nuvem de Magalhães e o restante na direção do Bojo Galáctico. A análise foi feita inspecionando-se visualmente cada curva de luz por erupções com as características acima mencionadas. Os resultados obtidos podem ser sumarizados como: descoberta de duas novas clássicas e 33 novas anãs. Além disso, pode-se mencionar a identificação de candidatas a outros tipos de variáveis como: estrelas simbióticas, RV Tauri, R Coronae Borealis, Miras, etc.

Optimal Design for Marker-assisted Gene Pyramiding in Cross Population  

PubMed Central

Marker-assisted gene pyramiding aims to produce individuals with superior economic traits according to the optimal breeding scheme which involves selecting a series of favorite target alleles after cross of base populations and pyramiding them into a single genotype. Inspired by the science of evolutionary computation, we used the metaphor of hill-climbing to model the dynamic behavior of gene pyramiding. In consideration of the traditional cross program of animals along with the features of animal segregating populations, four types of cross programs and two types of selection strategies for gene pyramiding are performed from a practical perspective. Two population cross for pyramiding two genes (denoted II), three population cascading cross for pyramiding three genes(denoted III), four population symmetry (denoted IIII-S) and cascading cross for pyramiding four genes (denoted IIII-C), and various schemes (denoted cross program-A–E) are designed for each cross program given different levels of initial favorite allele frequencies, base population sizes and trait heritabilities. The process of gene pyramiding breeding for various schemes are simulated and compared based on the population hamming distance, average superior genotype frequencies and average phenotypic values. By simulation, the results show that the larger base population size and the higher the initial favorite allele frequency the higher the efficiency of gene pyramiding. Parents cross order is shown to be the most important factor in a cascading cross, but has no significant influence on the symmetric cross. The results also show that genotypic selection strategy is superior to phenotypic selection in accelerating gene pyramiding. Moreover, the method and corresponding software was used to compare different cross schemes and selection strategies.

Nutritional status and epidemiological profile of elderly people.  

PubMed

We intended to identify and evaluate the association between the socio-demographic and epidemiological characteristics of elderly people with their nutritional characteristics. This is a transversal study PMTI (from the Portuguese name of "Programa Municipal da Terceira Idade"), conducted at Viçosa, MG, Brazil. We analyzed 93 records of elderly people registered since 2006 and who underwent nutritional care. After having analyzed the questionnaire, we performed the descriptive and association analyses in the Epi Info (version 6.04) and Minitab softwares. Of the 93 analyzed records, most elderly people were women (80.4%), with an average of 72 years of age, of which 13.0% were long-lived people. The mean body mass index (BMI) was 27.4 kg/m(2), and 50.5% were overweight. We have found 26.8% elderly patients with hypertension, and 31.6% took antihypertensives. Elderly patients who were overweight are 4.54 times more likely to have arterial hypertension (odds ratio (OR)=4.54; 95% confidence interval (CI)=1.2-2.45). Only 7.5% smoked, 30.1% were alcoholics and 60.2% made physical activities. Inadequacies were found regarding the servings of fruits, dairy products, vegetables and sugars consumed. However, the servings of cereals, leguminous, meat and fat consumed were appropriate. This study showed that the nutritional diagnosis and the epidemiological and socio-demographic studies are critical tools to understand this population group, in addition to being important to the planning of health actions.

The successful evolution of a voluntary vessel safety program in the USA.  

PubMed

The North Pacific Fishing Vessel Owners' Association (NPFVOA) is a non-profit association dedicated to safety education and training for commercial fishermen and other mariners. Funding is provided primarily through member contributions and also through tuition fees and sales of materials. Members are primarily fishing vessel owners and fishing-related companies, from small salmon boats with single operators to large processing ships with crews of 150 or more. The Association also works together with insurance underwriters and brokers, maritime attorneys and fishing industry support businesses. It works closely with the United States Coast Guard, the Occupational Safety and Health Administration (OSHA) of the United States Department of Labor, the National Institute for Occupational Safety and Health (NIOSH), and many state agencies. There are three primary components of the NPFVOA Vessel Safety Program--a comprehensive safety manual, a series of safety and survival at sea videotapes, and a crew training program. The vessel safety manual includes 300 pages of text and illustrations covering subjects ranging from vessel familiarity for deckhands to stability for the owner and skipper. It is based on the experience of those who have fished the Bering Sea and the North Pacific. The manual calls for vessel owners and skippers to adopt safety practices specific to the vessel's characteristics and service, the waters fished, the season fished and the experience of the crew. The safety and survival videotape series is designed to complement hands-on training classes. The crew training program uses hands-on practice to dramatize and enliven the information presented in the manual and on the videotapes. Courses are designed to be portable and conducted in numerous ports and states. The NPFVOA also publishes a quarterly newsletter covering its safety program, other relevant safety information and reports of lessons learned from serious fishing vessel accidents. PMID:17312697

A council of elders: creating a multi-voiced dialogue in a community of care.  

PubMed

In an era of 'medical care delivery systems', there is an increasing need for the patient's voice to be heard, for it to be invited, listened to, and taken seriously. This challenge is particularly evident in geriatrics education, a domain of clinical training in which educators and clinicians alike must struggle to overcome adverse attitudes towards the elderly ('ageism'). In this paper we introduce a 'Council of Elders' as an educational innovation in which we invited community elders to function as our 'Senior Faculty', to whom medical residents present their challenging and heartfelt dilemmas in caring for elder patients. In the conversations that ensue, the elders come to function not simply as teachers, but collaborators in a process in which doctors, researchers, and elders together create a community of resources, capable of identifying novel ways to overcome health-related difficulties which might not have been apparent to either group separately. Using the first meeting of the Council as an exemplar, we describe and discuss the special nature of such meetings and also the special preparations required to build a dialogic relationship between participants from very different worlds--different generations, different cultures (including the professional culture and the world of lived experience). Meetings with the council have become a required part of the primary care residency program--a very different kind of 'challenging case conference' in which moral dilemmas can be presented, discussed and reflected upon. It is not so much that elders give good advice in their responses--although they often do--as that they provide life world and value orientation as young residents gain a better sense of the elder's experience and what matters most to them. This project has been particularly worthwhile in addressing the problem of ageism--a way to render visible stereotypes and adverse physician values, with implications for decision-making with the patient, not for the patient.

Treatment of newly diagnosed acute promyelocytic leukemia (APL): a comparison of French-Belgian-Swiss and PETHEMA results.  

PubMed

All-trans retinoic acid (ATRA) plus anthracycline chemotherapy is the reference treatment of newly diagnosed acute promyelocytic leukemia (APL), whereas the role of cytosine arabinoside (AraC) remains disputed. We performed a joint analysis of patients younger than 65 years included in Programa para el Estudio de la Terapéutica en Hemopatía Maligna (PETHEMA) LPA 99 trial, where patients received no AraC in addition to ATRA, high cumulative dose idarubicin, and mitoxantrone, and APL 2000 trial, where patients received AraC in addition to ATRA and lower cumulative dose daunorubicin. In patients with white blood cell (WBC) count less than 10 x 10(9)/L, complete remission (CR) rates were similar, but 3-year cumulative incidence of relapse (CIR) was significantly lower in LPA 99 trial: 4.2% versus 14.3% (P = .03), although 3-year survival was similar in both trials. This suggested that AraC is not required in APL with WBC count less than 10 x 10(9)/L, at least in trials with high-dose anthracycline and maintenance treatment. In patients with WBC of 10 x 10(9)/L or more, however, the CR rate (95.1% vs 83.6% P = .018) and 3-year survival (91.5% vs 80.8%, P = .026) were significantly higher in APL 2000 trial, and there was a trend for lower 3-year CIR (9.9% vs 18.5%, P = .12), suggesting a beneficial role for AraC in those patients.

Comunicaci?n de pareja y VIH en mujeres en desventaja social  

PubMed Central

Introducción La epidemia de VIH y SIDA se ha diseminado rápidamente a nivel mundial tendiendo a la feminización, pauperización y heterosexualización. La comunicación de pareja en torno el VIH es descrita como uno de los factores protectores en la adquisición de esta enfermedad, favoreciendo la adopción de conductas sexuales seguras tales como la negociación de pareja y la utilización de preservativo, consideróndose como un pilar fundamental en la incorporación de medidas de autocuidado en la sexualidad femenina. Objetivo Determinar el nivel de comunicación de pareja en torno al VIH en mujeres chilenas en desventaja social. Metodología Cuatrocientas noventa y seis mujeres contestaron la entrevista inicial de la investigación “Testing an HIV/AIDS Prevention Intervention for Chilean Women” (RO1 TW 006977 PI Cianelli). Se utilizó la escala “Health protective sexual communication scale (HPC)” (0–10 puntos). Se realizó un análisis descriptivo utilizando el programa SPSS 16.0. Resultados El promedio del nivel de comunicación de pareja fue de 3,26 ± 2,7 puntos con la pareja principal, de 2,52 ± 2,48 puntos con una segunda pareja y de 0 puntos con una tercera pareja. Los temas de menor comunicación entre las parejas fueron el uso de preservativo y la realización del test para VIH antes de tener relaciones sexuales. Conclusión Las mujeres de la muestra presentan bajos niveles de comunicación de pareja en relación a VIH con todas sus parejas sexuales. Son necesarias estrategias que potencien este tópico dentro de las intervenciones de prevención de VIH y SIDA de manera de fortalecer la adopción de conductas de autocuidado en torno al tema.

Composição química, evolução e cinemática de estrelas de tipo solar  

NASA Astrophysics Data System (ADS)

A composição química das estrelas de tipo solar é um diagnóstico extremamente valioso da evolução química do disco da Galáxia. Existe alguma evidência de que tal evolução tem sido heterogênea no espaço e ao longo do tempo e que a composição química do Sol pode não ser um padrão representativo de abundâncias. Neste trabalho, foram obtidas as abundâncias dos elementos químicos C, N, Na, Mg, Si, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Sr, Y, Zr, Ba, La, Ce, Nd e Sm em uma amostra de estrelas de tipo solar na vizinhança solar (distâncias £ 25 pc). A técnica empregada foi a análise espectroscópica diferencial em relação ao Sol, baseando-se em dados de alta resolução (R ~ 46.000) e alta razão sinal/ruído (S/R > 300), obtidos com o espectrógrafo échelle de bancada do telescópio de 1,5 m do CTIO. Adicionalmente, abundâncias de C e N foram obtidas através de síntese de bandas moleculares dos Sistemas Eletrônicos Swan do C2 e Vermelho do CN utilizando-se um programa de síntese espectral. Os parâmetros atmosféricos foram estabelecidos usando cores fotométricas, o equilíbrio de excitação e ionização de linhas do Fe e a análise da temperatura e da luminosidade estelares no diagrama HR. Os resultados de abundâncias químicas obtidos proporcionam uma melhor compreensão da relação das abundâncias conhecidas para o Sol com a das estrelas anãs de tipo G da população local, uma vez que as razões de abundâncias de diversos elementos (em relação ao ferro) obtidas para estrelas de metalicidade semelhante à solar diferem daquelas obtidas para o Sol. Tais resultados também contribuem para um melhor entendimento do processo de evolução química da vizinhança solar e do enriquecimento nucleossintético do disco galáctico.

Um Projeto de Intervenção nos Espaços de Exposições do Planetário do Parque do Ibirapuera  

NASA Astrophysics Data System (ADS)

Cada vez mais a humanidade, em sua imensa maioria, está alheia às próprias conquistas. A insatisfação com esta realidade tem levado muitos pesquisadores, instituições, empresas e governos a procurar formas alternativas de acompanhar e transmitir todo este acervo científico cultural à sociedade, buscando a melhoria da qualidade da divulgação científica e contribuindo para o processo de cultura e alfabetização científica. Não há tempo nem espaço nos limitados planos curriculares do ensino médio e mesmo nos programas de ensino que propiciem a cultura científica e o acompanhamento do vertiginoso progresso científico e tecnológico atual. Neste sentido, a educação formal escolar precisa ser complementada ou acrescida de uma educação informal, extra-escolar, que possa oferecer à sociedade o que a escola não pode oferecer. A interação do público com museus, feiras de ciências, planetários, exposições científicas e/ou culturais é de grande importância para a aquisição e difusão de conhecimentos relacionados ao mundo científico. Reconhecidamente como um modelo de alfabetização científica esses ambientes promovem uma interação social capaz de propiciar de forma efetiva uma melhor relação ensino-aprendizagem com o público. Partindo desta realidade a Universidade Cruzeiro do Sul e a Escola Municipal de Astronomia (EMA) vêm desenvolvendo um projeto de intervenção no espaço em torno do Planetário do Parque do Ibirapuera com o objetivo de se implantar um ambiente de aprendizagem motivador e desafiador que promova a popularização de conteúdos relacionados à astronomia, astrofísica e cosmologia. Busca-se, também, a aproximação e interação do público com exposições que estão sendo implementadas no planetário. Considerando que se trata de um projeto de mestrado em fase inicial o objetivo do presente trabalho é apresentar a concepção básica e os critérios que estão sendo utilizados do ponto de vista pedagógico para as indicações dos objetos e experimentos que serão expostos, procurando formas de construir, expor e apresen! tá-los d e maneira mais eficiente em termos de uma aprendizagem significativa.

Seasonal precipitation extreme indices in mainland Portugal: trends and variability in the period 1941-2007  

NASA Astrophysics Data System (ADS)

Changes in the precipitation regimes are expected to be accompanied by variations in the occurrence of extreme events, which in turn could be related to low frequency variability. The impact on the society and environment requires that the regional specificities are understood. For mainland Portugal, this work reports the results of the analysis of trends in selected precipitation indices calculated from daily precipitation data from 57 meteorological stations, recorded in the period 1941-2007; additionally we have also investigated the correlations between these indices and several modes of low frequency variability over the area. We focus on exploring regional differences and seasonal variations in the intensity, frequency and duration of extreme precipitation events. The precipitation indices were assessed at the seasonal scale and calculated at both the station and regional scales. Results sometimes highlight marked changes in seasonal precipitation and show that: i) trends in spring and autumn have opposite signals: statistically significant drying trends in the spring are accompanied by a reduction in precipitation extremes; in autumn, wetting trends are detected for all precipitation indices, although overall they are not significant at the 5% level; ii) there seems to be a tendency for a reduction in the duration of the rainy season; iii) the North Atlantic Oscillation (NAO) is the mode of variability that has the highest influence on precipitation extremes over mainland Portugal, particularly in the winter and autumn, and is one of the most important teleconnection patterns in all seasons. This work was partially supported by FEDER (Fundo Europeu de Desenvolvimento Regional) funds through the COMPETE (Programa Operacional Factores de Competitividade) and by national funds through FCT (Fundação para a Ciência e a Tecnologia, Portugal) through project STORMEx FCOMP-01-0124-FEDER-019524 (PTDC/AAC-CLI/121339/2010).

Astronomia para/com crianças carentes em Limeira  

NASA Astrophysics Data System (ADS)

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. Conclui com uma avaliação do que tal projeto representou para as Instituições participantes. Para o Observatório, em particular, foi feita uma análise com relação às outras modalidades de atendimentos que envolvem alunos de escolas e público em geral. Também é abordada a questão do compromisso social do Observatório na educação do público em questão.

Cash and in-kind transfers lead to excess weight gain in a population of women with a high prevalence of overweight in rural Mexico.  

PubMed

There is a growing concern that food or cash transfer programs may contribute to overweight and obesity in adults. We studied the impact of Mexico's Programa de Apoyo Alimentario (PAL), which provided very poor rural households with cash or in-kind transfers, on women's body weight. A random sample of 208 rural communities in southern Mexico was randomly assigned to 1 of 4 groups: food basket with or without health and nutrition education, cash with education, or control. The impact on women's weight was estimated in a cohort of 3010 women using a difference-in-difference model. We compared the impact between the food basket and cash groups and evaluated whether the impact was modified by women's BMI status at baseline. With respect to the control group, the program increased women's weight in the food basket (550 ± 210 g; P = 0.004) and the cash group (420 ± 230 g; P = 0.032); this was equivalent to 70 and 53% increases in weight gain, respectively, over that observed in the control group in a 23-mo time period. The greatest impact was found in already obese women: 980 ± 290 g in the food basket group (P = 0.001) and 670 ± 320 g in the cash group (P = 0.019). Impact was marginally significant in women with a preprogram BMI between 25 and 30 kg/m2: 490 ± 310 g (P = 0.055) and 540 ± 360 g (P = 0.067), respectively. No program impact was found in women with a BMI <25 kg/m2. Providing households with a considerable amount of unrestricted resources led to excess weight gain in an already overweight population. Research is needed to develop cost-effective behavior change communication strategies to complement cash and in-kind transfer programs such as PAL and to help beneficiaries choose healthy diets that improve the nutritional status of all family members.

History and growth of radiation oncology in Indonesia.  

PubMed

In order to assess its progress, and to obtain a snapshot of the current situation, the Indonesian Radiation Oncology Society has routinely conducted annual surveys since 2004 to assess the current condition of resources for equipment and staffing in all radiation oncology centres in the country. Based on these routine surveys, the society has made recommendations to the government about providing cancer patients with better and more affordable access to radiotherapy services.Questionnaires in hard and soft copy forms were distributed annually to Indonesian Radiation Oncology Society members, and all 22 centres (19 in 2004) responded by sending back the completed questionnaires. The obtained data was compared with results of the first survey in 2004.In 2008, there were 22 radiotherapy centres in Indonesia, 18 Linear Accelerators and 17 cobalt units. There were 270 radiation oncology professionals, including 41 radiation oncologists, 38 medical physicists, 6 dosimetrists, 125 radiation therapy technologists, and 60 nurses. In addition, there were 17 residents and trainees participating in the Radiation Oncology training program.A lot of progress had been made in the four-year period from 2004 to 2008. Indonesia has seen the establishment of 4 new centres, which indicates a 50% increase in the number of available treatment units, and a 29% increase in the number of human resources. These achievements were possible because more attention has been placed on cancer care issues in Indonesia, a great success due to the advocacy efforts of the Society. However, numerous issues still need urgent attention from all the stakeholders. PMID:21611007

Field Courses for Volcanic Hazards Mapping at Parícutinand Jorullo Volcanoes (Mexico)  

NASA Astrophysics Data System (ADS)

During the last decades, Mexico has suffered several geologic phenomena-related disasters. The eruption of El Chichón volcano in 1982 killed >2000 people and left a large number of homeless populations and severe economic damages. The best way to avoid and mitigate disasters and their effects is by making geologic hazards maps. In volcanic areas these maps should show in a simplified fashion, but based on the largest geologic background possible, the probable (or likely) distribution in time and space of the products related to a variety of volcanic processes and events, according to likely magnitude scenarios documented on actual events at a particular volcano or a different one with similar features to the volcano used for calibration and weighing geologic background. Construction of hazards maps requires compilation and acquisition of a large amount of geological data in order to obtain the physical parameters needed to calibrate and perform controlled simulation of volcanic events under different magnitude-scenarios in order to establish forecasts. These forecasts are needed by the authorities to plan human settlements, infrastructure, and economic development. The problem is that needs are overwhelmingly faster than the adjustments of university programs to include courses. At the Earth Science División of the Faculty of Engineering at the Universidad Nacional Autónoma de México, the students have a good background that permits to learn the methodologies for hazards map construction but no courses on hazards evaluations. Therefore, under the support of the university's Program to Support Innovation and Improvement of Teaching (PAPIME, Programa de Apoyo para la Innovación y Mejoramiento de la Enseñanza) a series of field-based intensive courses allow the Earth science students to learn what kind of data to acquire, how to record, and process in order to carry out hazards evaluations. This training ends with hazards maps that can be used immediately by the authorities after proper review by peers. This project has been running for two years and hazards maps for the region of Parícutin and Jorullo volcanoes have been carried out. The students have been applying their knowledge and got results in a very short time and at the same time socially very important.

Análise Temporal da Coma de CO+ no Cometa P/Halley  

NASA Astrophysics Data System (ADS)

Observações fotográficas e fotoelétricas da coma de gás ionizado do cometa P/Halley a nível de CO+ em 4250 angstroms fizeram parte do programa de Monitoramento do Halley desenvolvido pela Universidade de Bochum (Ruhr-Universitaet Bochum) na Alemanha, realizado de 17 de fevereiro a 17 de abril de 1986 no European Southern Observatory (ESO) em La Silla (Chile). Nesta faixa espectral é possível observar a contínua formação, bem como o movimento e expansão das estruturas de plasma. Para observar a morfologia destas estruturas foram analisadas 32 placas fotográficas de CO+ (placas de vidro) do cometa P/Halley. Tais placas possuem um campo de visão de 28,6 por 28,6 graus sendo obtidas entre 29 de março e 17 de abril de 1986 com tempos de exposição entre 20 e 120 minutos. Todas as placas foram digitadas com o auxílio de um microdensitômetro PDS 2020 GM (Photometric Data System) do Instituto Astronómico da Westfaelischen Wilhelms-Universitaet em Muenster, Alemanha (um pixel = 25 por 25 micrômetros correspondendo aproximadamente a 46,88 por 46,88 segundos de arco). Após a digitação os dados foram reduzidos à intensidades relativas, sendo que os posssíveis de calibração também foram reduzidos à intensidades absolutas, expressas em termos de densidade colunar utilizando-se dos sistemas de tratamento de imagens MIDAS (Munich Image Data Analysis System; ESO - Image Processing Group, 1988) e IHAP (Image Handling And Processing; Middleburg, 1983). Com o auxílio do método de teta mínimo de Stellingwerf (Stellingwerf, 1978) obteve-se um período de 2,22 +/- 0,09 dias a partir da análise de estruturas na coma de plasma através da subtração de imagens subsequentes. Este método foi comparado com o método de Fourier. Provavelmente exista um segundo ciclo com período aproximado de 3,6 dias. A idéia de subtrair imagens subsequentes é devido ao fato de que os efeitos de rotação são apenas 10% dos fenômenos de distribuição gasosa. Portanto as imagens de diferença são usadas para suprimir a componente estática da nuvem de gás. - ESO - Image Processing Group, 1988, in: MIDAS Manual, ESO, Garching. - Middleburg F., 1983, in: IHAP Manual, ESO, Garching. - Stellingwerf R.F., 1978, ApJ 224, 953.

Characteristics of storms that contribute to extreme precipitation events over the Iberian Peninsula  

NASA Astrophysics Data System (ADS)

Floods correspond to one of the most deadly natural disasters in the Iberian Peninsula during the last century. Quite often these floods are associated to intense low pressure systems with an Atlantic origin. In recent years a number of episodes have been evaluated on a case-by-case approach, with a clear focus on extreme events, thus lacking a systematic assessment. In this study we focus on the characteristics of storms for the extended winter season (October to March) that are responsible for the most extreme rainfall events over large areas of the Iberian Peninsula. An objective method for ranking daily precipitation events during the extended winter is used based on the most comprehensive database of high resolution (0.2º latitude by 0.2º longitude) gridded daily precipitation dataset available for the Iberian Peninsula. The magnitude of an event is obtained after considering the total area affected as well as its intensity in every grid point (taking into account the daily normalised departure from climatology). Different precipitation rankings are studied considering the entire Iberian Peninsula, Portugal and also the six largest river basins in the Iberian Peninsula (Duero, Ebro, Tagus, Minho, Guadiana and Guadalquivir). Using an objective cyclone detecting and tracking scheme [Trigo, 2006] the storm track and characteristics of the cyclones were obtained using the ERA-Interim reanalyses for the 1979-2008 period. The spatial distribution of extratropical cyclone positions when the precipitation extremes occur will be analysed over the considered sub-domains (Iberia, Portugal, major river basins). In addition, we distinguish the different cyclone characteristics (lifetime, direction, minimum pressure, position, velocity, vorticity and radius) with significant impacts in precipitation over the different domains in the Iberian Peninsula.

The XVII International Conference on Strings, Particles and Cosmology, PASCOS 2012, was held in the City of Mérida, Mexico, from June 3–8, 2012. The conference series is aimed at exploring the interface and interplay between particle physics, string theory and cosmology. With the advent of new data, the emphasis of the XVIII edition of PASCOS was on phenomenology and the interpretation of recent observational and experimental results. The conference followed the format of previous conferences in this series, with plenary reviews and contributed presentations in parallel sessions. The lectures covered a wide range of subjects which included: Dark matter and dark energy, flavor physics and CP violation, neutrino physics, supersymmetry, Higgs physics, baryogenesis and EDMs, supergravity, high energy cosmic rays, string and F–theory GUTs, and string phenomenology. This is the first time that PASCOS was held in Latin America. The aim to do it in Mexico was to engage the Latin American community and thus to bring the conference to a wider and different audience, a goal which was thoroughly achieved. The venue was held at the Hotel Fiesta Americana in the beautiful city of Mérida. The social events included a reception with typical local food at the Katun restaurant, conference dinner at the historical Quinta Montes Molina, and an excursion to the archeological site of Dzibilchaltún including a swim at the famous cenote.

Effect of acclimation to outdoor condition on the sexual performance of mass-produced Medflies (Diptera: Tephritidae)  

SciTech Connect

Application of the sterile insect technique (SIT) as part of integrated area-wide programs to control the Mediterranean fruit fly (medfly) Ceratitis capitata (Wiedemann) require that the released males attract wild females and transfer sterile sperm. However, knowledge about male sexual performance after they are released is scarce. We conducted a study to evaluate male sexual performance in field cage tests, according to standard quality control procedures. Mass-reared 5-d-old sterile males from the genetic sexing strain VIENNA 7mix2000 were acclimated for 0, 1, and 3 d to outdoor conditions before competing with wild males for wild females. Although the proportion of mating (PM) in the test was satisfactory, the resulting relative sterility index (RSI) data showed no significant differences among the treatments. The data indicate that pre-conditioning males to outdoor conditions in Madeira did not confer an advantage in field cage sexual performance. (author) [Spanish] La aplicacion de la tecnica del insecto esteril (TIE) como parte de un programa integrado de amplio efecto para el control de la mosca mediterranea de la fruta Ceratitis capitata (Wiedemann) requiere que los machos liberados atraigan las hembras naturales y transfieran su esperma. Sin embargo, el conocimiento del desempeno sexual de los machos despues de ser liberados es muy escaso. Nosotros realizamos un estudio para evaluar el desempeno sexual de los machos en pruebas usando jaulas del campo, segun los procedimientos estandardizados de calidad. Machos esteriles de 5 dias de edad de la raza que separa los sexos geneticamente VIENNA 7mix2000 criados en masa fueron aclimatados por 0, 1 y 3 dias en condiciones de campo antes de competir con machos naturales para las hembras naturales. Aunque la proporcion del apareamiento en la prueba fue satisfactorio, el indice relativo de esterilidad (IRS) resultante no mostro ninguna diferencia significativa entre los tratamientos. Los datos indicaron que al condicionar los machos anteriormente a las condiciones de campo en Madeira no conferio ventaja alguna en el desempeno sexual en la jaula de campo. (author)

Precipitation effects on aerosol concentration in the background EMEP station of Zarra (Valencia), Spain  

NASA Astrophysics Data System (ADS)

Aerosols and precipitation are closely related, presenting a bidirectional influence and constituting an important source of uncertainties on climate change studies. However, they are usually studied independently and in general are only linked to one another for the development or validation of cloud models. The primary and secondary pollutants may be removed by wet and dry deposition. Wet deposition, including in-cloud and below-cloud scavenging processes, can efficiently remove atmospheric aerosols and it is considered a critical process for determining aerosol concentrations in the atmosphere. In this study, aerosols and precipitation data from a background Spanish EMEP (Cooperative Programme for the Monitoring and Evaluation of Long Range Transmission of Air Pollutants in Europe) station located in Zarra, Valencia (Spain) were analyzed (1° 06' W and 39° 05' N, 885 m asl). The effect of precipitation on aerosol concentration was studied and the correlation between the intensity of precipitation and scavenging effect was investigated. In order to evaluate the effects of precipitation on different aerosol size ranges three different aerosol fractions were studied: PM10, PM10-2.5 and PM2.5. In order to eliminate the influence of the air mass changes, only the days in which the air mass of the precipitation day and the previous day had the same origin were considered. Thus, from a total of 3586 rainy days registered from March 2001 to December 2010, 34 precipitation days satisfied this condition and were analyzed. During the period of study, daily precipitation ranged between 0.2 and 28.8 mm, with a mean value of 4 mm. Regarding the origin of the air masses, those from west were dominant at the three height levels investigated (500, 1500 and 3000 m). In order to obtain additional information, aerosol and precipitation chemical composition were also studied in relation to the days of precipitation and the previous days. Furthermore, in order to identify the type of weather associated with each particular synoptic situation, a Circulation Weather Type (CWT) classification was applied.

Compilação de dados atômicos e moleculares do UV ao IV próximo para uso em síntese espectral  

NASA Astrophysics Data System (ADS)

Espectros sintéticos são utéis em uma grande variedade de aplicações, desde análise de abundâncias em espectros estelares de alta resolução ao estudo de populações estelares em espectros integrados. A confiabilidade de um espectro sintético depende do modelo de atmosfera adotado, do código de formação de linhas e da qualidade dos dados atômicos e moleculares que são determinantes no cálculo das opacidades da fotosfera. O nosso grupo no departamento de Astronomia no IAG tem utilizado espectros sintéticos há mais de 15 anos, em aplicações voltadas principalmente para a análise de abundâncias de estrelas G, K e M e populações estelares velhas. Ao longo desse tempo, as listas de linhas vieram sendo construídas e atualizadas continuamente, e alguns acréscimos recentes podem ser citados: Castilho (1999, átomos e moléculas no UV), Schiavon (1998, bandas moleculares de TiO) e Melendez (2001, átomos e moléculas no IV próximo). Com o intuito de calcular uma grade de espectros do UV ao IV próximo para uso no estudo de populações estelares velhas, se fazia necessário compilar e homogeneizar as diversas listas em apenas uma lista atômica e uma molecular. Nesse processo, a nova lista compilada foi correlacionada com outras bases de dados (NIST, Kurucz Database, O' Brian et al. 1991) para atualização dos parâmetros que caracterizam a transição atômica (comprimento de onda, log gf e potencial de excitação). Adicionalmente as constantes de interação C6 foram calculadas segundo a teoria de Anstee & O'Mara (1995) e artigos posteriores. As bandas moleculares de CH e CN foram recalculadas com o programa LIFBASE (Luque & Crosley 1999). Nesse poster estão detalhados os procedimentos citados acima, as comparações entre espectros calculados com as novas listas e espectros observados em alta resolução do Sol e de Arcturus, e uma análise do impacto decorrente da utilização de diferentes modelos de atmosfera no espectro sintético. Ao final, temos uma lista de linhas atômicas com mais de 24.000 linhas e uma lista molecular com as moléculas CN, CH, OH, NH, MgH, C2, TiO Gama, CO, FeH, adequadas ao estudo de estrelas G, K e M e populações estelares velhas.

Analysis of Minimum Efficiency Performance Standards for Residential General Service Lighting in Chile  

SciTech Connect

Minimum Efficiency Performance Standards (MEPS) have been chosen as part of Chile's national energy efficiency action plan. As a first MEPS, the Ministry of Energy has decided to focus on a regulation for lighting that would ban the sale of inefficient bulbs, effectively phasing out the use of incandescent lamps. Following major economies such as the US (EISA, 2007) , the EU (Ecodesign, 2009) and Australia (AS/NZS, 2008) who planned a phase out based on minimum efficacy requirements, the Ministry of Energy has undertaken the impact analysis of a MEPS on the residential lighting sector. Fundacion Chile (FC) and Lawrence Berkeley National Laboratory (LBNL) collaborated with the Ministry of Energy and the National Energy Efficiency Program (Programa Pais de Eficiencia Energetica, or PPEE) in order to produce a techno-economic analysis of this future policy measure. LBNL has developed for CLASP (CLASP, 2007) a spreadsheet tool called the Policy Analysis Modeling System (PAMS) that allows for evaluation of costs and benefits at the consumer level but also a wide range of impacts at the national level, such as energy savings, net present value of savings, greenhouse gas (CO2) emission reductions and avoided capacity generation due to a specific policy. Because historically Chile has followed European schemes in energy efficiency programs (test procedures, labelling program definitions), we take the Ecodesign commission regulation No 244/2009 as a starting point when defining our phase out program, which means a tiered phase out based on minimum efficacy per lumen category. The following data were collected in order to perform the techno-economic analysis: (1) Retail prices, efficiency and wattage category in the current market, (2) Usage data (hours of lamp use per day), and (3) Stock data, penetration of efficient lamps in the market. Using these data, PAMS calculates the costs and benefits of efficiency standards from two distinct but related perspectives: (1) The Life-Cycle Cost (LCC) calculation examines costs and benefits from the perspective of the individual household; and (2) The National Perspective projects the total national costs and benefits including both financial benefits, and energy savings and environmental benefits. The national perspective calculations are called the National Energy Savings (NES) and the Net Present Value (NPV) calculations. PAMS also calculate total emission mitigation and avoided generation capacity. This paper describes the data and methodology used in PAMS and presents the results of the proposed phase out of incandescent bulbs in Chile.

Diagnosis and Modeling of the Explosive Development of Winter Storms: Sensitivity to PBL Schemes  

NASA Astrophysics Data System (ADS)

The correct representation of extreme windstorms in regional models is of great importance for impact studies of climate change. The Iberian Peninsula has recently witnessed major damage from winter extratropical intense cyclones like Klaus (January 2009), Xynthia (February 2010) and Gong (January 2013) which formed over the mid-Atlantic, experienced explosive intensification while travelling eastwards at lower latitudes than usual [Liberato et al. 2011; 2013]. In this paper the explosive development of these storms is simulated by the advanced mesoscale Weather Research and Forecasting Model (WRF v 3.4.1), initialized with NCEP Final Analysis (FNL) data as initial and lateral boundary conditions (boundary conditions updated in every 3 hours intervals). The simulation experiments are conducted with two domains, a coarser (25km) and nested (8.333km), covering the entire North Atlantic and Iberian Peninsula region. The characteristics of these storms (e.g. wind speed, precipitation) are studied from WRF model and compared with multiple observations. In this context simulations with different Planetary Boundary Layer (PBL) schemes are performed. This approach aims at understanding which mechanisms favor the explosive intensification of these storms at a lower than usual latitudes, thus improving the knowledge of atmospheric dynamics (including small-scale processes) on controlling the life cycle of midlatitude extreme storms and contributing to the improvement in predictability and in our ability to forecast storms' impacts over Iberian Peninsula.

Exobiology opportunities from Discovery-class missions. [Abstract only  

NASA Technical Reports Server (NTRS)

Discovery-class missions that are now planned, and those in the concept stage, have the potential to expand our knowledge of the origins and evolution of biogenic compounds, and ultimately, of the origins of life in the solar system. This class of missions, recently developed within NASA's Solar System Exploration Program, is designed to meet important scientific objectives within stringent guidelines--$150 million cap on development cost and a 3-year cap on the development schedule. The Discovery Program will effectively enable "faster, cheaper" missions to explore the inner solar system. The first two missions are Mars Environmental Survey (MESUR) Pathfinder and Near Earth Asteroid Rendezvous (NEAR). MESUR Pathfinder will be the first Discovery mission, with launch planned for November/December 1996. It will be primarily a technical demonstration and validation of the MESUR Program--a network of automated landers to study the internal structure, meteorology, and surface properties of Mars. Besides providing engineering data, Pathfinder will carry atmospheric instrumentation and imaging capabilities, and may deploy a microrover equipped with an alpha proton X-ray spectrometer to determine elemental composition, particularly the lighter elements of exobiological interest. NEAR is expected to be launched in 1998 and to rendezvous with a near-Earth asteroid for up to 1 year. During this time, the spacecraft will assess the asteroid's mass, size, density, map its surface topography and composition, determine its internal properties, and study its interaction with the interplanetary environment. A gamma ray or X-ray spectrometer will be used to determine elemental composition. An imaging spectrograph, with 0.35 to 2.5 micron spectral range, will be used to determine the asteroid's compositional disbribution. Of the 11 Discovery mission concepts that have been designated as warranting further study, several are promising in terms of determining the composition and chemical evolution of organic matter on small planetary bodies. The following mission concepts are of particular interest to the Exobiology Program: Cometary coma chemical composition, comet nucleus tour, near earth asteroid returned sample, small missions to asteroids and comets, and solar wind sample return. The following three Discovery mission concepts that have been targeted for further consideration are relevant to the study of the evolution of biogenic compounds: Comet nucleus penetrator, mainbelt asteroid rendezvous explorer, and the Mars polar Pathfinder.

Analysis of moisture advection during explosive cyclogenesis over North Atlantic Ocean  

NASA Astrophysics Data System (ADS)

The development of a mid-latitude cyclone may strongly be amplified by the presence of a very warm and moist air mass within its warm sector through enhanced latent heat release. In this work, a lagrangian approach is applied to examine the contribution of moisture advection to the deepening of cyclones over the North Atlantic Ocean. The warm sector is represented by a 5°x5° longitude/latitude moving box comprising the centre of the cyclone and its south-eastern area is defined for the tracks of different cyclones computed at 6-hourly intervals. Using the lagrangian particle model FLEXPART we evaluated the fresh water flux (E - P) along 2-days back-trajectories of the particles residing on the total column over the defined boxes for case studies occurring during winter months from 1980 to 2000. FLEXPART simulations were performed using one degree resolution and 60 model vertical levels available in ERA40 Reanalyses at 00, 06, 12, 18 UTC for each case. Sensitivity studies on the dimensions of the target area - chosen boxes representing the warm sector -, and on its relative position to the center, were performed. We have applied this methodology to several case studies of independent North Atlantic cyclones with notorious characteristics (e.g. deepening rate, wind speed, surface damages). Results indicate that the moisture transport is particularly relevant in what concerns the fast/explosive development stage of these extratropical cyclones. In particular, the advection of moist air from the subtropics towards the cyclone core is clearly associated with the warm conveyor belt of the cyclone. This methodology can be generalized to a much larger number of mid-latitude cyclones, providing a unique opportunity to analyze the moisture behavior associated with the explosive development.

ZPR-6 assembly 7 high {sup 240} PU core : a cylindrical assemby with mixed (PU, U)-oxide fuel and a central high {sup 240} PU zone.  

SciTech Connect

Over a period of 30 years more than a hundred Zero Power Reactor (ZPR) critical assemblies were constructed at Argonne National Laboratory. The ZPR facilities, ZPR-3, ZPR-6, ZPR-9 and ZPPR, were all fast critical assembly facilities. The ZPR critical assemblies were constructed to support fast reactor development, but data from some of these assemblies are also well suited to form the basis for criticality safety benchmarks. Of the three classes of ZPR assemblies, engineering mockups, engineering benchmarks and physics benchmarks, the last group tends to be most useful for criticality safety. Because physics benchmarks were designed to test fast reactor physics data and methods, they were as simple as possible in geometry and composition. The principal fissile species was {sup 235}U or {sup 239}Pu. Fuel enrichments ranged from 9% to 95%. Often there were only one or two main core diluent materials, such as aluminum, graphite, iron, sodium or stainless steel. The cores were reflected (and insulated from room return effects) by one or two layers of materials such as depleted uranium, lead or stainless steel. Despite their more complex nature, a small number of assemblies from the other two classes would make useful criticality safety benchmarks because they have features related to criticality safety issues, such as reflection by soil-like material. The term 'benchmark' in a ZPR program connotes a particularly simple loading aimed at gaining basic reactor physics insight, as opposed to studying a reactor design. In fact, the ZPR-6/7 Benchmark Assembly (Reference 1) had a very simple core unit cell assembled from plates of depleted uranium, sodium, iron oxide, U3O8, and plutonium. The ZPR-6/7 core cell-average composition is typical of the interior region of liquid-metal fast breeder reactors (LMFBRs) of the era. It was one part of the Demonstration Reactor Benchmark Program,a which provided integral experiments characterizing the important features of demonstration-size LMFBRs. As a benchmark, ZPR-6/7 was devoid of many 'real' reactor features, such as simulated control rods and multiple enrichment zones, in its reference form. Those kinds of features were investigated experimentally in variants of the reference ZPR-6/7 or in other critical assemblies in the Demonstration Reactor Benchmark Program.

Achieving Conservation Science that Bridges the Knowledge-Action Boundary  

PubMed Central

There are many barriers to using science to inform conservation policy and practice. Conservation scientists wishing to produce management-relevant science must balance this goal with the imperative of demonstrating novelty and rigor in their science. Decision makers seeking to make evidence-based decisions must balance a desire for knowledge with the need to act despite uncertainty. Generating science that will effectively inform management decisions requires that the production of information (the components of knowledge) be salient (relevant and timely), credible (authoritative, believable, and trusted), and legitimate (developed via a process that considers the values and perspectives of all relevant actors) in the eyes of both researchers and decision makers. We perceive 3 key challenges for those hoping to generate conservation science that achieves all 3 of these information characteristics. First, scientific and management audiences can have contrasting perceptions about the salience of research. Second, the pursuit of scientific credibility can come at the cost of salience and legitimacy in the eyes of decision makers, and, third, different actors can have conflicting views about what constitutes legitimate information. We highlight 4 institutional frameworks that can facilitate science that will inform management: boundary organizations (environmental organizations that span the boundary between science and management), research scientists embedded in resource management agencies, formal links between decision makers and scientists at research-focused institutions, and training programs for conservation professionals. Although these are not the only approaches to generating boundary-spanning science, nor are they mutually exclusive, they provide mechanisms for promoting communication, translation, and mediation across the knowledge–action boundary. We believe that despite the challenges, conservation science should strive to be a boundary science, which both advances scientific understanding and contributes to decision making. Logrando que la Ciencia de la Conservación Trasponga la Frontera Conocimiento-Acción Resumen Hay muchas barreras para utilizar ciencia para informar a la política y práctica de la conservación. Los científicos de la conservación que desean producir ciencia relevante para el manejo deben equilibrar esta meta con el imperativo de demostrar novedad y rigor en su ciencia. Los tomadores de decisiones que buscan que sus decisiones se basen en evidencias deben equilibrar el deseo de conocimientos con la necesidad de actuar a pesar de la incertidumbre. La generación de ciencia que informe efectivamente a las decisiones de manejo requiere que la producción de información (los componentes del conocimiento) sea sobresaliente (relevante y oportuna), creíble (autoritativa, verosímil y confiable) y legítima (desarrollada mediante un proceso que considera los valores y perspectivas de todos los actores relevantes) a la vista tanto de investigadores como de tomadores de decisiones. Percibimos tres retos clave para quienes desean generar ciencia de la conservación que logre estas tres características de la información. Primero, las audiencias científicas y de manejo pueden tener percepciones contrastantes sobre la relevancia de la investigación. Segundo, la credibilidad se puede lograr a costa de la relevancia y legitimidad a la vista de los tomadores de decisiones y tercero, los diferentes actores pueden tener percepciones conflictivas sobre los que constituye información legítima. Resaltamos cuatro marcos institucionales que pueden facilitar que la ciencia informe al manejo: organizaciones de frontera (organizaciones ambientales que trasponen la frontera entre la ciencia y el manejo), investigadores científicos insertados en agencias de manejo de recursos, vínculos formales entre tomadores de decisiones y científicos en instituciones enfocadas a la investigación, y programas de

Sexual performance of mass reared and wild Mediterranean fruit flies (Diptera: Tephritidae) from various origins of the Madeira Islands  

SciTech Connect

The success of Mediterranean fruit fly (medfly) Ceratitis capitata (Wiedemann) control programs integrating the sterile insect technique (SIT) is based on the capacity of released the sterile males to compete in the field for mates. The Islands of Madeira are composed of 2 populated islands (Madeira and Porto Santo) where the medfly is present. To evaluate the compatibility and sexual performance of sterile flies we conducted a series of field cage tests. At same time, the process of laboratory domestication was evaluated. 3 wild populations, one semi-wild strain, and 1 mass reared strain were evaluated: the wild populations of (1) Madeira Island (north coast), (2) Madeira Island (south coast), and (3) Porto Santo Island; (4) the semi-wild population after 7 to 10 generations of domestication in the laboratory (respectively, for first and second experiment); and (5) the genetic sexing strain in use at Madeira medfly facility (VIENNA 7mix2000). Field cage experiments showed that populations of all origins are mostly compatible. There were no significant differences among wild populations in sexual competitiveness. Semi-wild and mass-reared males performed significantly poorer in both experiments than wild males in achieving matings with wild females. The study indicates that there is no significant isolation among strains tested, although mating performance is reduced in mass-reared and semi-wild flies after 7 to 10 generations in the laboratory. (author) [Spanish] El exito de los programas de control de la mosca mediterranea de la fruta (Ceratitis capitata (Wiedemann) que integran la tecnica del insecto esteril (TIE) esta basado en la capacidad de machos esteriles para competir en el campo por sus parejas. Las Islas de Madeira consisten de 2 islas pobladas (Madeira y Porto Santo) donde la mosca mediterranea de la fruta esta presente. Para evaluar la compatibilidad y el funcionamiento sexual de moscas esteriles nosotros realizamos una serie de pruebas de jaula en el campo. Al mismo tiempo, el proceso de la domesticacion en el laboratorio fue evaluado. Tres poblaciones naturales, una poblacion semi-natural y una poblacion criada en masa fueron evaluadas: las poblaciones natural de (1) Isla de Madeira (costa norte), (2) Isla de Madeira (costa sur) y (3) Isla de Porto Santo; (4) una poblacion semi-natural despues de 7 a 10 generaciones de domesticacion en el laboratorio (respectivamente, para el primero y segundo experimento); y (5) la raza para separar sexos geneticamente que es usada en el laboratorio de la mosca mediterranea de Madeira (VIENNA 7mix2000). Los experimentos usando jaulas en el campo mostraron que las poblaciones de diferentes origines fueron en su mayor parte compatibles. No hubo diferencias significativas en la capacidad para competir sexualmente entre las poblaciones naturales. Los machos semi-naturales y los machos criados en masa mostraron un desempeno significativamente bajo en ambos experimentos que los machos naturales en el logro de copula con las hembras naturales. Este estudio indica que no hay un aislamiento significativo entre las razas probadas, aunque el desempeno en el apareamiento fue reducido en las moscas criadas en masa y semi-naturales despues de 7 a 10 generaciones en el laboratorio.

Dinámica y crecimiento de los granos de polvo en la nebulosa protoplanetaria  

NASA Astrophysics Data System (ADS)

En el escenario estándar de la formación planetaria, los planetesimales (cuerpos de tamaño kilométrico) crecen a partir de granos de polvo, similares a los interestelares, embebidos en un disco gaseoso denominado nebulosa protoplanetaria. Durante esta etapa, los movimientos del gas pueden tener gran influencia en la dinámica y el crecimiento de los granos de polvo, dado que el flujo kepleriano del gas frena el movimiento de los mismos haciendo que caigan hacia el Sol, y la turbulencia inhibe la inestabilidad gravitacional de la capa de polvo. Aunque se acepta que los planetesimales fueron los elementos constituyentes de los planetas, todavía se desconoce cómo se produjo la formación de los mismos. Por esta razón, en los estudios más recientes, existe un renovado interés por comprender mejor la evolución de la capa de polvo inmersa en el disco gaseoso de la Nebulosa. El gas que fluye en el disco puede engendrar estructuras carentes de simetría axial, como por ejemplo ondas espirales y vórtices, a partir de gran variedad de mecanismos de excitación e inestabilidad. En 1995, Barge y Sommeria pusieron de manifiesto que la existencia de vórtices gaseosos persistentes en la nebulosa solar tendría importantes consecuencias sobre la formación de los planetesimales y el posterior crecimiento de los planetas gigantes. La investigación desarrollada en esta Tesis analiza la relación entre el polvo y el gas debida al acoplamiento por fricción dinámica entre ambos; en concreto, se estudia el efecto del flujo medio del gas sobre la dinámica de las partículas de polvo. El primer objetivo es investigar en profundidad los procesos de captura y crecimiento de los granos de polvo dentro de un vórtice y su posible relevancia en cuanto a la formación de los planetesimales. El segundo objetivo es la exploración de los efectos de ondas espirales propagándose en el disco gaseoso sobre la dinámica y el crecimiento de las partículas. La presencia de líneas de corriente no circulares perturba significativamente el movimiento de las partículas alrededor del Sol e incrementa su vida media en la Nebulosa. El flujo medio del gas se modela de forma simple, analizándose la dinámica y el crecimiento de las partículas mediante simulaciones numéricas. Al incrementarse la vida media y la densidad superficial de las partículas sólidas, los mecanismos de confinamiento derivados de la presencia de vórtices y ondas espirales actuan sobre el material sólido de la Nebulosa (mediante agregación colisional o inestabilidades gravitacionales) de manera mucho más eficiente que la previamente considerada. Esto ofrece nuevas posibilidades para la formación de planetesimales y núcleos de planetas gigantes, y puede explicar la formación rápida de planetas extrasolares gigantes. Además, esta Tesis analiza la respuesta de las partículas, en un disco protoplanetario con un radio de 100 UA en torno a una estrella de tipo solar, al campo gravitatorio derivado de la presencia de dos estrellas compañeras ligadas en una órbita relativamente elongada (300-1600 UA). Para llevar a cabo este análisis, se han realizado una serie de simulaciones numéricas de configuraciones jerárquicas coplanares utilizando un programa FORTRAN que integra directamente las ecuaciones del movimiento con el objeto de modelar la presencia de las fuerzas gravitacionales y viscosas. El disco protoplanetario masivo se encuentra en torno a una de las componentes de la binaria. La evolución temporal del subdisco de polvo depende directamente de la naturaleza (directa o retrógrada) de la revolución relativa de la compañera estelar, y de la temperatura y la masa del disco circunestelar.

What has happened in about the last 20 years in the Canyoles watershed?  

NASA Astrophysics Data System (ADS)

Along history, the Mediterranean arid lands have undergone widespread land use transformation, especially in recent decades (Piqueras, 2012). There are changes driven by socio-economic conditions, such as European Agricultural Policies (MacDonald et al., 2000; Keenleyside and Tucker, 2010; Renwick et al., 2013), which have caused land degradation processes (soil erosion, soil sealing, water pollution, salinization, wildfires, land abandonment, urban sprawl and intensive agricultural practices). Land degradation is the results of a complex Socio Ecological System (SES) which should be addressed using the Geographical Information System (GIS) to identify and assess the spatial variation of land use change. Therefore, the aim of this work has been to describe and assess the land use change by human activities in a typical Mediterranean watershed (Cànyoles Valley) located at South-East of Iberian Peninsula as a part of the Land Ecosystem and Degradation Desertification Response Assessment (LEDDRA) project, which has undergone a quick land use change in last two decades (1986 - 2005). Results reveal that the surface area devoted to rainfed crops (e.g., olive crops (47 %) and vineyards (28 %) and forestry have decline significantly; while the citrus orchards (irrigated crops) and unproductive areas (e.g., roads and railways, urban areas) have been increasing its surface in just about last 20 years in 45 % and 67 %, respectively. According to the literature review (Cerdà, 1994; Cerdá et al., 1999, 2007; Cerdà, 2007; Bodí et al., 2012; González-Peñaloza, 2012) these recent changes, in the study site, have caused many environmental disturbances mainly due to the lack control strategies plans of land degradation.

Production and quality assurance in the SIT Africa Mediterranean fruit fly (Diptera: Tephritidae) rearing facility in South Africa  

SciTech Connect

A mass-rearing facility for Mediterranean fruit fly Ceratitis capitata (Wiedemann) was commissioned in Stellenbosch in 1999 to produce sterile male fruit flies for a sterile insect technique (SIT) project in commercial fruit orchards and vineyards in the Western Cape province of South Africa. The mass-rearing procedure was largely based on systems developed by the FAO/IAEA Agriculture and Biotechnology Laboratory, Seibersdorf, Austria. A number of genetic sexing strains were used to produce only males for release. Initial cramped rearing and quality management conditions were alleviated in 2001 with the construction of a new adult rearing room and quality control laboratory. In 2002 a comprehensive Quality Management System was implemented, and in 2003 an improved genetic sexing strain, VIENNA 8, was supplied by the FAO/IAEA Laboratory in Seibersdorf. For most of the first 3 years the facility was unable to supply the required number of sterile male Mediterranean fruit flies for the SIT program without importing sterile male pupae from another facility. From mid-2002, after the quality management system was implemented, both production and quality improved but remained below optimum. After the introduction of the VIENNA 8 genetic sexing strain, and together with an improvement in the climate control equipment, production stability, and quality assurance parameters improved substantially. The critical factors influencing production and quality were an inadequate rearing infrastructure, problems with the quality of the larval diet, and the initial absence of a quality management system. The results highlight the importance of effective quality management, the value of a stable and productive genetic sexing strain, and the necessity for a sound funding base for the mass-rearing facility. (author) [Spanish] La facilidad para criar en masa la mosca mediterranea de la fruta, Ceratitis capitata (Wiedemann) fue comisionada en Stellenbosch en 1999 para producir machos esteriles de moscas para el proyecto de la tecnica del insecto esteril (TIE) en huertos de frutos y vinas comerciales en la provincia del Cabo Occidental del Sudafrica. El procedimiento de criar en masa fue en su mayor parte basado en los sistemas desarrollados por el Laboratorio de Agricultura y Biotecnologia de la FAO/IAEA, Seibersdorf, Austria. Un numero de razas que separara los sexos geneticamente fueron utilizadas para producir solo machos para la liberacion. La congestionada condicion inicial para criar las moscas y su manejo de calidad fueron aliviadas en 2001 con la construccion de un nuevo cuarto de cria para adultos y un laboratorio de control de calidad. En 2002, un Sistema de Manejo de Calidad comprensivo fue implementado, y en 2003 una raza mejorada que separa los sexos geneticamente, VIENNA 8, fue proveido por el Laboratorio de la FAO/IAEA en Seibersdorf. En la mayor parte de los primeros 3 anos la facilidad no pudo suplir el numero requerido de machos esteriles de la mosca mediterranea de la fruta para el programa de TIE sin la necesidad para importar machos esteriles de otra facilidad. Desde medio del ano de 2002, despues que el sistema de manejo de calidad fue implementado, la produccion y la calidad mejoraron pero aun quedaron por debajo del nivel optimo. Despues de la introduccion de la raza VIENNA 8 que separa los sexos geneticamente, y junto con el equipo mejorado de control de clima, la estabilidad y los parametros de seguridad de calidad mejoraron substancialmente. Los factores criticos que influyeron en la produccion y la calidad fueron la infraestructura inadecuada para criar las moscas, problemas con la calidad de la dieta para las larvas y la ausencia inicial de un sistema de manejo de calidad. Los resultados muestran claramente la importancia de un manejo efectivo de la calidad, el valor de una raza productiva que separa los sexos geneticamente y la necesidad de contar con una base solida de financimiento para la infraestructura de una cria en masa.

Daily precipitation extreme events for the Iberian Peninsula and its association with Atmospheric Rivers  

NASA Astrophysics Data System (ADS)

Extreme precipitation events in the Iberian Peninsula during the extended winter months have major socio-economic impacts such as floods, landslides, extensive property damage and life losses. These events are usually associated with low pressure systems with Atlantic origin, although some extreme events in summer/autumn months can be linked to Mediterranean low pressure systems. Quite often these events are evaluated on a casuistic base and making use of data from relatively few stations. An objective method for ranking daily precipitation events is presented here based on the extensive use of the most comprehensive database of daily gridded precipitation available for the Iberian Peninsula (IB02) and spanning from 1950 to 2008, with a resolution of 0.2° (approximately 16 x 22 km at latitude 40°N), for a total of 1673 pixels. This database is based on a dense network of rain gauges, combining two national data sets, 'Spain02' for peninsular Spain and Balearic islands, and 'PT02' for mainland Portugal, with a total of more than two thousand stations over Spain and four hundred stations over Portugal, all quality-controlled and homogenized. Through this objective method for ranking daily precipitation events the magnitude of an event is obtained after considering the area affected as well as its intensity in every grid point and taking into account the daily precipitation normalised departure from climatology. Different precipitation rankings are presented considering the entire Iberian Peninsula, Portugal and also the six largest river basins in the Iberian Peninsula. Atmospheric Rivers (AR) are the water vapour (WV) core section of the broader warm conveyor belt occurring over the oceans along the warm sector of extra-tropical cyclones. They are usually W-E oriented steered by pre-frontal low level jets along the trailing cold front and subsequently feed the precipitation in the extra-tropical cyclones. They are relatively narrow regions of concentrated WV responsible for horizontal transport in the lower atmosphere. It was shown that more than 90% of the meridional WV transport in the mid-latitudes occurs in the AR, although they cover less than 10% of the area of the globe. The large amount of WV that is transported can lead to heavy precipitation and floods. In this work we use an automated AR detection algorithm for the North Atlantic Ocean Basin to identify the major AR events that affected the Iberian Peninsula based on the NCEP/NCAR reanalysis. The two different databases (extreme precipitation events and AR) will be analysed together in order to study ARs in detail in the North Atlantic Basin and, additionally, the relationship with precipitation-related events in Iberian Peninsula. Results confirm the significance link between these phenomena, as the TOP 20 days of the ranking of precipitation anomalies for the Iberian Peninsula includes 19 days that are clearly related with AR events.

Caracterización espectroscópica de hielos de interés atmosférico y astrofísico  

NASA Astrophysics Data System (ADS)

En años recientes se ha incrementado el estudio de procesos físicos y químicos que tienen lugar en la superficie o el interior de hielos, tanto en medios astrofísicos como en la atmósfera terrestre y en otros cuerpos del sistema solar. Se ha comprobado que las partículas heladas actúan como catalizadores de reacciones químicas, que no ocurrirían en su ausencia. En la atmósfera terrestre, es bien conocida la importancia de partículas de hidratos de ácido nítrico, formando las llamadas nubes estratosféricas polares, en los procesos de destrucción de ozono estratosférico. En hielos astrofísicos, átomos como H, C, N y O pueden adherirse o introducirse en la estructura cristalina o amorfa del hielo, y dar lugar a reacciones de formación de moléculas evitando su barrera de activación. Existen partículas heladas en el medio interestelar formando parte de las llamadas nubes moleculares densas y frías, con valores del orden de 106 átomos de H por cm3 y temperaturas entre 3 y 90 K. Alrededor de protoestrellas, pueden formarse hielos de distinta composición, polares o apolares, en las zonas de alejamiento y temperatura decreciente a partir del núcleo caliente. Por su parte, los cometas están formados por un núcleo de hielo y rocas, sobre el que se encuentran adheridas moléculas gaseosas, y una cola, formada por los gases liberados por efecto del calentamiento debido a la radiación solar incidente. En nuestro sistema solar, los polos de La Tierra y de Marte están cubiertos de hielo, así como la mayoría de los cuerpos externos. Los satélites de Júpiter han sido estudiados detalladamente, y se han encontrado en ellos, y en Tritón (satélite de Neptuno), hielos de moléculas como SON2, CO2, N2, CH4 y otros. Para la caracterización espectroscópica de estos hielos se precisan medidas en el laboratorio, aún conociendo la imposibilidad intrínseca de reproducir exactamente las condiciones en que se formaron y se encuentran en los medios astrofísicos. El montaje experimental requiere un sistema que permita alcanzar bajas presiones y temperaturas, formado usualmente por una cámara en cuyo interior se forman películas de hielo de la composición deseada, depositadas sobre un sustrato inerte. Las películas pueden ser a continuación tratadas por diversas técnicas, tales como irradiación UV, bombardeo con electrones o iones, calentamiento y enfriamiento, etc. Habitualmente todos los procesos se controlan por espectroscopía de infrarrojo. La radiación proveniente de un espectrómetro se hace incidir sobre la muestra y se extrae de la cámara mediante ventanas, y se enfoca posteriormente sobre el detector. En el laboratorio de Física Molecular del Instituto de Estructura de la Materia disponemos de un montaje experimental diseñado para el estudio de partículas de hielo similares a las formadas en las nubes estratosféricas polares de nuestra atmósfera. El montaje es similar al descrito anteriormente, excepto en lo que se refiere a las condiciones de presión y temperatura, que son menos estrictas en nuestros experimentos. La extensión de estas condiciones de trabajo a las requeridas en medios astrofísicos es una posibilidad a discutir. Por otra parte, disponemos de un método de cálculo de estructuras periódicas, basado en el programa SIESTA (acrónimo de Spanish Initiative for Electronic Simulations of Thousands of Atoms), que ha proporcionado excelentes resultados en lo relativo a la determinación de estructuras cristalinas y predicción de su espectro infrarrojo, en los sistemas estudiados hasta la fecha, es decir, los hidratos de ácido nítrico de interés atmosféricos. Su aplicación para el estudio de hielos de relevancia astrofísica podría ser del máximo interés.

Since 2011, the University of Malaga's Central Research Service (SCAI) has been responsible for maintaining the herbariums and the dataset. The collection is growing continuously, with an annual intake of about 1.500 specimens. Nearly 96% of the collection is digitized, by Herbar v3.7.1 software (F. Pando et al. 1996-2011), making over 73.000 specimens accessible through the GBIF network (http://data.gbif.org/datasets/resource/8105/). At present, 247 families and 8.110 taxa, distributed in angiosperms (93.97%), ferns and fern allies (4.89%) and gymnosperms (1.14%), constitute the MGC-Cormof collection. The families and genera best represented in the collection are Compositae, Leguminosae, Gramineae, Labiatae, Caryophyllaceae, Teucrium, Silene, Asplenium, Linaria and Quercus. Most of the specimens are from the Western Mediterranean Region, fundamentally Southern Spain (Andalusia: 82% of specimens) and Northern Morocco (2.17%). Approximately, 63% of the specimens are georeferenced. The identification of the specimens in the collection has been carried out by the plant biology department at the University of Malaga and plus 40% of the specimens has been reviewed by experts. The MGC-Cormof dataset has been revised by DarwinTest v3.2 tool (Ortega-Maqueda and Pando 2008) before being published in GBIF. The data included in this database are important for conservation works, taxonomy, flora, cartography, phenology, palynology, among others.

Late magmatic stage of the zoned Caleu pluton (Central Chile): insights from zircon crystallization conditions  

NASA Astrophysics Data System (ADS)

The Caleu pluton consists of three N-S elongated lithological zones: Gabbro-Diorite Zone (GDZ), Tonalite Zone (TZ) and Granodiorite Zone (GZ); western, middle and eastern portions of the pluton, respectively. The zones are thought to be previously differentiated in a common, isotopically depleted (Sr-Nd), subjacent magma reservoir at a 4 kbar equivalent depth. The emplacement should have occurred at the climax of the Cretaceous rifting. We present preliminary results of U238/Pb206 zircon geochronology; zircon saturation, Tsat(Zrn), and crystallization temperatures (Ti-in-Zrn); as well as relative oxidation states at time of crystallization, based on: (i) the sluggish REE and HFSE subsolidus diffusivities in zircon; (ii) the behavior of Ti4+?Si4+ and Ce4+?Zr4+ isovalent replacement, in addition to a constrained TiO2 activity in almost all typical crustal rocks; and (iii) relative oxidation states at time of crystallization, respectively. The latter are obtained by interpolation of the partition coefficients of trivalent (REE) and tetravalent (HFSE) curves in Onuma diagrams for each zircon, and then estimating relative Ce(IV)/Ce(III) ratios. Results obtained from 4 samples (a total of 77 zircon grains) collected from the three mentioned lithological zones indicate U/Pb ages of approximately 99.5 ±1.5 Ma, 96.8 ±0.6 Ma, and 94.4 +2.2 -0.8 Ma; and Ti-in Zrn ranges of ca. 720-870°C, ca. 680-820°C and ca. 750-840°C, for the GDZ, TZ and GZ samples, respectively. On the other hand Tsat(Zrn) of ca. 750-780°C in the TZ, and ca. 830-890°C in the GZ, were obtained. As expected saturation temperatures are similar or higher than Ti-in-Zrn obtained in zircon grains of TZ and GZ, respectively. Cathodoluminiscence images in zircon suggest a magmatic origin, due to absence of complex zoning patterns and fairly well conserved morphologies. Exceptionally the GDZ sample zircons show evidence of inheritance, indicating a xenocrystic and/or antecrystic origin. A relative Ce(IV)/Ce(III) decrease with temperature gives rise to separate trends for each zone, suggesting an independent unbuffered development at time of zircon formation. Taking into account variations in zircon ages, morphologies and crystallization ranges in the collected samples, it is suggested that zircon crystallization took place independent of the magma composition. Furthermore, old inherited zircon grains in the GDZ could be antecrysts, or products of a restricted and not major host rock assimilation, owing to the impossibility of basaltic magmas to saturate zircon crystals, and the isotopically depleted signature. This study is financed by CONICYT-FONDAP grant 15090013, Centro de Excelencia en Geotermia de los Andes (CEGA); and the CONICYT PBCT-PDA07, Programa Bicentenario de Ciencia y Tecnología.

The use of normalized climatological anomalies to rank precipitation events in the Iberian Peninsula  

NASA Astrophysics Data System (ADS)

Extreme precipitation events in the Iberian Peninsula during winter months have major socio-economic impacts such as flooding, landslides, extensive property damage and life losses, and are usually associated to deep low pressure systems with Atlantic origin, although some extreme events in summer/autumn months are fed by the Mediterranean. Quite often these events are evaluated on a casuistic base and with relatively few stations. An objective method for ranking daily precipitation events is presented based on the extensive use of the most comprehensive database of daily precipitation available for the Iberian Peninsula (IB02) and spanning from 1950 to 2003, with a resolution of 0.2° (approximately 16 x 22 km at latitude 40°N), for a total of 1673 pixels. This database is based on a dense network of rain gauges, combining two national data sets, 'Spain02' for peninsular Spain and Balearic islands (Herrera et al., 2012), and 'PT02' for mainland Portugal (Belo-Pereira et al., 2011), with a total of more than two thousand stations over Spain and four hundred stations over Portugal, all quality-controlled and homogenized. The daily precipitation data from 1950 to 2003 are compared with a 30-year (1961-90) precipitation climatology to achieve a daily normalized departure from the climatology. The magnitude of an event is given daily by an index that is obtained after multiplying 1) the area (in percentage) that has precipitation anomalies above two standard deviations by 2) the mean values of these anomalies over this area. With this criterion we are able to evaluate not only the spatial extent of the precipitation events but also their spatially integrated intensity. In addition, to stress out the hydrological responses to precipitation, rankings taking into account the sum of the normalized anomalies over different time periods (3 days, 5 days and 10 days) were also computed. Here different precipitation rankings will be presented considering the entire Iberian Peninsula but also most major river basins in the Iberian Peninsula (Minho, Douro, Tejo, Guadiana, Guadalquivir and Ebro). A selection of historical events will allow a quantitative evaluation both of the method and of the meteorological conditions in different regions of the Iberian Peninsula of the most anomalous events.

Airborne Soil Moisture determination at regional level: A data fusion mission approach for Catalan territory  

NASA Astrophysics Data System (ADS)

During the last years the importance of water management has grown considerably. Average temperatures exhibit an increasing pattern (0.77 °C during the last 20 years) that is expected to continue in the next years. These results in a decrease in the hydrical resources (15% during the last 20 years for the Catalan territori) being the expectative not very optimist. A tangible consequence was the drought episode that suffers Catalonia. It is within this scenario that the ‘Programa Català d'Observació de la Terra' (PCOT) as a unit of the official mapping agency of Catalonia, the ‘Institut Cartogràfic de Catalunya' (ICC) has detected the need to develop new tools to improve the management of water resources. The knowledge of soil moisture across a given region can help to efficiently manage the limited water resources. Present Earth Observations missions such as ESA's SMOS, or the future NASA's SMAP focus considerably their efforts in the estimation of soil moisture. The main drawbacks are the resolutions obtained (40 km for SMOS, 10 km for SMAP), which are not adequate for regional scale and territorial availability such as the case of Catalonia where a spatial resolution in a range between 20-30m. and 100-150m. is desired both for local actuations and to deteminate hidric soil patterns In this scenario, PCOT is carrying out an airborne soil moisture mission for the Catalan territory, taking advantage of the availability of ICC aircrafts and of more than 20 years of experience in making aircraft campaigns and operating hyperspectral airborne sensors such as CASI (0.75-1.4 µm) and TASI (8-11.5 µm) to respond to environmental and cartographic end users needs of geoinformation data, products and services. This mission will generate soil moisture maps over the Catalan region that will improve the water management, and will also be used for the study of the hydrological patterns of Catalonia. Soil moisture determination will be achieved by means of L-band radiometry, using a radiometer designed by the Passive Remote Sensing Group of the ‘Universitat Politècnica de Catalunya' (UPC). Spatial resolution enhancement or vegetation cover and surface roughness compensation will be improved by means of data fusion by using the operational CASI and TASI instruments flight simultaneously. Thus, L-band radiometer measurements will be combined with thermal and hyperspectral sensor measurements to obtain surface temperature and vegetation indexes, and thus allow improving the retrieval soil moisture. This airborne soil moisture mission program is supported by a Torres Quevedo grant awarded by the Spanish Ministry of Science and Innovation as well as by ICC/PCOT as one of the Earth Observation Demostration Program on the Water Cycle area of activity (named RADERO-Airborne Radiometry) . Running in parallel of technical and operational identification of drivers, RADERO takes into acount as a third paramount pillar, to guarantee the usefulness of RADERO, the improvement of awareness and feedback with end users. RADERO mission has set up an advisory board to check the mission analysis and design, under the supervision of the Catalan Agriculture Department among other scientific and potential end users.

Tools for evaluating Lipolexis oregmae (Hymenoptera: Aphidiidae) in the field: Effects of host aphid and host plant on mummy location and color plus improved methods for obtaining adults  

SciTech Connect

Lipolexis oregmae Gahan was introduced into Florida in a classical biological control program directed against the brown citrus aphid, Toxoptera citricida (Kirkaldy), on citrus. Prior to evaluating distribution, host range, and potential nontarget effects of L. oregmae in Florida, we evaluated the role of other potential host aphids and host plants on mummy production and location. Under laboratory conditions, this parasitoid produced the most progeny on the target pest, the brown citrus aphid on citrus. This parasitoid, unlike the majority of aphidiids, did not produce mummies on any of the host plants tested when reared in black citrus aphid T. aurantii (Boyer de Fonscolombe) on grapefruit, spirea aphid Aphis spiraecola Patch on grapefruit and pittosporum, cowpea aphid A. craccivora Koch on grapefruit and cowpeas, or melon aphid A. gossypii Glover on grapefruit and cucumber. Thus, sampling for L. oregmae mummies of these host aphids and host plants must involve holding foliage in the laboratory until mummies are produced. This parasitoid requires high relative humidity to produce adults because no adults emerged when mummies were held in gelatin capsules, but high rates of emergence were observed when mummies were held on 1.5% agar plates. In addition, we compared the color of 6 aphid hosts and the color of mummies produced by L. oregmae when reared in them to determine if color of mummies could be used to identify L. oregmae . Mummy color varied between aphid hosts and tested host plants, and is not a useful tool for identifying L. oregmae for nontarget effects. (author) [Spanish] Lipolexis oregmae Gahan fue introducida en Florida por medio de un programa de control biologico clasico dirigido contra el afido pardo de los citricos, Toxoptera citricida (Kirkaldy), sobre Citrus. Prioritario a la evaluacion de la distribucion, el rango de los hospederos y los efectos potenciales de L. oregmae sobre los organismos que no son el enfoque de control en la Florida, nosotros evaluamos el papel de otras especies de afidos y plantas hospederas potenciales sobre la produccion y ubicacion de las momias. Bajo condiciones de laboratorio, este parasitoide produjo el mayor numero de progenies sobre la especie de plaga enfocada, el afido pardo de los citricos sobre Citrus . Este parasitoide, no como la mayoria de los afidiidos (Hymenoptera), no produjo momias sobre cualquiera de las plantas hospederas probadas cuando fue criado sobre el afido negro de los citricos, ( T. aurantii (Boyer de Fonscolombe)) en toronja, el afido spirea (Aphis spiraecola Patch) en toronja y pittosporum, el afido del caupi (A. craccivora Koch) en toronja y caupi o el afido del melon (A. gossypii Glover) en toronja y pepino. Asi, el muestreo para momias de L. oregmae de estas especies de afidos hospederos y plantas hospederas tiene que incluir el mantenimiento de follaje en el laboratorio hasta que se produzcan las momias. Este parasitoide requiere una alta humedad relativa para producir los adultos por que ningun adulto emergio cuando las momias fueron mantenidas en capsulas de gelatina, pero una tasa alta de emergencia de adultos fue observada cuando se mantuvo las momias en platos con agar al 1.5%. Ademas de esto, nosotros comparamos el color de 6 especies de afidos hospederos, asi como el color de las momias producidos por L. oregmae cuando fue criado sobre ellos para determinar si se puede usar el color de las momias para la identificacion de L. oregmae . El color de las momias varia entre las especies de afidos hospederos y las plantas hospederas probadas, por lo que no es una herramienta util para la identificacion de L. oregmae o para la evaluacion de su efecto sobre los organismos que no son el enfoque del control.

Lekking behavior of Anastrepha Fraterculus (Diptera: Tephritidae)  

SciTech Connect

Anastrepha fraterculus (Wiedemann) (Diptera: Tephritidae) displays a lek mating system. Males form groups in which they simultaneously display signals (acoustical, visual, or chemical) to attract females with the purpose of mating. Females visit the lek and choose among signaling and courting males to mate. Scarce information is available in A. fraterculus about the main factors involved in female choice and the behavior of displaying males. This information could be important within the context of pest control programs with a sterile insect technique (SIT) component, because departures from normal sexual behavior caused by artificial rearing could affect males' performance in the field. In this study we assessed A. fraterculus male behavior within the leks and analyzed the importance of behavioral and morphological traits on their copulatory success. The existence of preferred places for lek formation was evaluated in field cages with trees inside and analyzed by dividing the trees in sectors according to a 3-dimensional system. Males were individually weighed, marked, and observed every 15 min. Morphometric and behavioral characteristics of successful and unsuccessful males were compared. Most successful males grouped in a region of the tree characterized by the highest light intensity in the first 2 h of the morning. Results showed that pheromone calling activity is positively associated with copulatory success. Copulations were more frequent for males calling inside the lek, indicating that pheromone calling activity and presence in the lek are key factors for copulatory success. A positive association between copulatory success and eye length was found; some characteristics of the face were also associated with copula duration and latency. (author) [Spanish] Anastrepha fraterculus (Wiedemann) (Diptera: Tephritidae) presenta un sistema de apareamiento tipo lek. Los machos forman grupos y, en forma conjunta, emiten senales (acusticas, visuales, o quimicas) para atraer a las hembras con el proposito de aparearse. Las hembras visitan el lek y eligen entre los machos para copular. La informacion acerca de los principales factores involucrados en la eleccion de la hembra y de la influencia del comportamiento de los machos en los leks en esta eleccion es escasa para A. fraterculus . Esta informacion es importante en el contexto de programas de control que incluyen la Tecnica del Insecto Esteril. En el presente estudio se evaluo el comportamiento sexual de machos de A. fraterculus dentro de los leks, y la asociacion de su comportamiento y de rasgos morfometricos con el exito copulatorio. El lugar preferido de agrupamiento de los machos fue evaluado en jaulas de campo con arboles en su interior y dividiendo el arbol en sectores de acuerdo a un sistema de tres dimensiones. Los machos fueron individualmente pesados, marcados y observados cada quince minutos. Luego de finalizado el ensayo se midieron los rasgos morfometricos. El mayor exito correspondio a machos agrupados en una region del arbol caracterizada por tener la mayor intensidad de luz en las dos primeras horas de la manana. Los resultados mostraron que la actividad de llamado con feromonas esta asociada con el exito copulatorio. Las copulas fueron mas frecuentes para machos que llamaron dentro del lek, indicando que la actividad de llamado con feromonas y la presencia dentro del lek son factores importantes en la obtencion de la copula. Los analisis morfometricos revelaron una asociacion positiva entre el exito copulatorio y el largo del ojo, y que algunas caracteristicas de la cara estan asociadas ademas con la duracion de la copula y la latencia.

A participatory approach to integrated aquifer management: The case of Guanajuato State, Mexico  

NASA Astrophysics Data System (ADS)

Guanajuato State, located in central Mexico, with less than 2% of the country's area, has almost 17,000 deep water wells, from which nearly 4,000 cubic hectometers (hm3) per year are being extracted, more than 1,000 hm3 over the estimated renewable yield. Since, in Mexico, water is administered under federal jurisdiction by the National Water Commission (CNA, for its Spanish acronym), the state government faces the challenge of ensuring its population's economic development without formal means of intervention. Being thus limited to apply mandatory policies and measures, the state water program has focused on the implementation of a two-sided strategy. First, basic hydrogeological studies and mathematical groundwater hydrodynamic models were developed upon a comprehensive survey of existing wells and a general revision of the state's geological framework. Second, a structure for water user's participation in water management actions was promoted (from the dissemination of information to the implementation of pilot efficient water use projects) with financial, technical and political support from the state. Simultaneously, a coordinated effort towards the completion of the water user's registry was performed with the federal authority along with other supporting measures such as training and monitoring programs. In this paper, a general overview of the project's achievements and challenges is presented. L'État de Guanajuato, situé dans la partie centrale du Mexique, avec moins de 2% de la surface du pays, a près de 17 000 puits profonds, d'où sont extraits près de 4 000 hm3 par an, soit plus de 1 000 hm3 de plus que le débit renouvelable estimé. Comme au Mexique l'eau est administrée dans le cadre d'une juridiction fédérale, le gouvernement de l'État fait tout son possible pour assurer le développement de sa population sans moyens formels d'intervention. Étant ainsi limité à appliquer des politiques et des mesures de recommandations, le programme Eau de l'État s'est appliqué à développer une stratégie sur deux plans. Tout d'abord, des études hydrogéologiques de base et des modèles mathématiques d'écoulement et de transport de nappe ont été réalisés à partir d'un suivi d'ensemble des puits existants et d'une révision générale du contexte géologique de l'État. Ensuite, on a soutenu une structure de participation des usagers de l'eau aux actions de gestion de l'eau, à partir de la dissémination de l'information pour la mise en place de projets pilotes efficaces d'utilisation de l'eau, avec des aides financières, techniques et politiques de l'État. Simultanément, un effort coordonné en vue de l'achèvement de l'enregistrement des usagers de l'eau a été fait avec l'autorité fédérale, en même temps que d'autres mesures de soutien, telles que des programmes de formation et des campagnes de surveillance. Cet article présente une vue d'ensemble des réalisations de projets et des défis. Resumen El Estado de Guanajuato, situado en el centro de México, ocupa menos del 2% de la superficie del país. Tiene casi 17.000 pozos profundos, de los cuales se extrae cerca de 4.000 hm3/a, lo que supone un exceso de 1.000 hm3/a respecto a la recarga anual. Puesto que el agua es administrada a nivel federal en México, el gobierno del Estado afronta el reto de asegurar el desarrollo de la población sin disponer de medios formales de intervención. Dadas las limitaciones para aplicar políticas y medidas reguladoras, el programa del agua en el Estado tiene como objetivo principal la implantación de una doble estrategia. Por un lado, desarrollar estudios hidrogeológicos básicos y modelos matemáticos de flujo y transporte de los acuíferos, basándose en una campaña exhaustiva de pozos existentes y en una revisión del marco geológico del Estado. Por otro lado, promover-con soporte financiero, técnico y político-una estructura de participación de los usuarios en las acciones de gestión, incluyendo desde la difusión de la información hasta la implantación de proyectos piloto para un uso
