  1. Barrio Adentro and the reduction of health inequalities in Venezuela: an appraisal of the first years.

    PubMed

    Armada, Francisco; Muntaner, Caries; Chung, Haejoo; Williams-Brennan, Leslie; Benach, Joan

    2009-01-01

    This article presents an update on the characteristics and performance of Venezuela's Bolivarian health care system, Barrio Adentro (Inside the Neighborhood). During its first five years of existence, Barrio Adentro has improved access and utilization of health services by reaching approximately 17 million impoverished and middle-class citizens all over Venezuela. This was achieved in approximately two years and provides an example of an immense "South-South" cooperation and participatory democracy in health care. Popular participation was achieved with the Comités de Salud (health committees) and more recently with the Consejos Comunales (community councils), while mostly Cuban physicians provided medical care. Examination of a few epidemiological indicators for the years 2004 and 2005 of Barrio Adentro reveals the positive impact of this health care program, in particular its primary care component, Barrio Adentro I. Continued political commitment and realistic evaluations are needed to sustain and improve Barrio Adentro, especially its primary care services. PMID:19326784

  14. Taxonomic status of Pseudopaludicola riopiedadensis Mercadal de Barrio and Barrio, 1994 (Anura, Leptodactylidae, Leiuperinae).

    PubMed

    Cardozo, Darío; Toledo, Luís Felipe

    2013-01-01

    Pseudopaludicola riopiedadensis was described by Mercadal de Barrio and Barrio (1994) based on two adult females collected by Luiz Dino Vizotto in 1963 from Rio Piedade, São José do Rio Preto, São Paulo, Brazil. This taxon was differentiated from P. ternetzi based on a series of qualitative and morphometric characters. Nevertheless, the original description and the type material of P. ternetzi were not considered by Mercadal de Barrio and Barrio, and the morphological variation of P. ternetzi was not documented. This work reviews the sample collected by Vizotto in P. riopiedadensis type locality, evaluates the advertisement calls obtained from such population, the two vouchers assigned to P. riopiedadensis, and a large data set, including type specimens of P. ternetzi to document the morphological variation along its known distribution. Results indicate that P. riopiedadensis was described on the basis of highly variable characters applied to a small sample and share the unique P. ternetzi autapomorphy, a robust body structure with immaculate belly. The lack of differentiation in both advertisement call and morphology rejects the status of P. riopiedadensis as distinct species, and we therefore suggest to formally consider P. riopiedadensis as junior synonym of P. ternetzi.

  7. Care and survival of Mexican American women with node negative breast cancer: historical cohort evidence of health insurance and barrio advantages.

    PubMed

    Richter, Nancy L; Gorey, Kevin M; Haji-Jama, Sundus; Luginaah, Isaac N

    2015-06-01

    We hypothesized 3-way ethnicity by barrio by health insurance interactions such that the advantages of having adequate health insurance were greatest among Mexican American (MA) women who lived in barrios. Barrios were neighborhoods with relatively high concentrations of MAs (60% or more). Data were analyzed for 194 MA and 2,846 non-Hispanic white women diagnosed with, very treatable, node negative breast cancer in California between 1996 and 2000 and followed until 2011. Significant interactions were observed such that the protective effects of Medicare or private health insurance on radiation therapy access and long term survival were largest for MA women who resided in MA barrios, neighborhoods that also tended to be extremely poor. These paradoxical findings are consistent with the theory that more facilitative social and economic capital available to MA women in barrios enables them to better absorb the indirect and direct, but uncovered, costs of breast cancer care.

  9. El barrio de la Chueca of Madrid, Spain: an emerging epicenter of the global LGBT civil rights movement.

    PubMed

    Martinez, Omar; Dodge, Brian

    2010-01-01

    The purpose of this article is to examine and deconstruct the lesbian, gay, bisexual, and transgender (LGBT) barrio (community) of Chueca in Madrid, Spain, from political and sociological perspectives. First, we develop a critical framework for understanding the historical, political, social, cultural, and economic changes that took place in Spain after Franco's death in relation to LGBT issues. Ethnographic research was conducted from May to July 2007 in the Spanish cities of Madrid, Barcelona, and Ibiza, and focused primarily on the community of Chueca. A social constructionist perspective was used to examine sociocultural issues in this ethnosexual community through an in-depth study of the dynamics of this barrio. The theoretical framework of intersectionality and the constitutive relations among social identities is exemplified in Chueca. Hence, individuals in Chueca and their intersectionality perspective reveal that their identities influence and shape their beliefs about gender and symbols. We describe how Chueca reflects recent progressive changes in LGBT-related laws and statutes drafted by the federal government and how these have influenced the high level of societal acceptance toward intimate same-sex relationships in Spain. Additionally, we exemplify and present Chueca as an enclave that has been affected by the globalization of the private market, "gay" identity, and enterprise, having a direct effect on cultural norms and social behaviors. Last, we examine the current state of the Chueca community relative to other developing LGBT Latino/a communities in the United States. PMID:20390991

  11. Challenging the neoliberal trend: the Venezuelan health care reform alternative.

    PubMed

    Muntaner, Carles; Salazar, René M Guerra; Rueda, Sergio; Armada, Francisco

    2006-01-01

    Throughout the 1990s, all Latin American countries but Cuba implemented to varying degrees health care sector reforms underpinned by a neoliberal paradigm that redefined health care as less of a social right and more of a market commodity. These health care sector reforms were couched in the broader structural adjustment of Latin American welfare states prescribed consistently by international financial institutions since the mid-1980s. However, since 2003, Venezuela has been developing an alternative to this neoliberal trend through its health care reform program called Misión Barrio Adentro (Inside the Neighbourhood). In this article, we introduce Misión Barrio Adentro in its historical, political, and economic contexts. We begin by analyzing Latin American neoliberal health sector reforms in their political economic context, with a focus on Venezuela. The analysis reveals that the major beneficiaries of both broader structural adjustment of Latin American welfare states and neoliberal health reforms have been transnational capital interests and domestic Latin American elites. We then provide a detailed description of Misión Barrio Adentro as a challenge to neoliberalism in health care in its political economic context, noting the role played in its development by popular resistance to neoliberalism and the unique international cooperation model upon which it is based. Finally, we suggest that the Venezuelan experience may offer valuable lessons not only to other low- to middle-income countries, but also to countries such as Canada. PMID:17203729

    PubMed

    Reimão, Sandra

    2013-11-30

    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.

  16. A comprehensive smoking cessation program for the San Francisco Bay Area Latino community: Programa Latino Para Dejar de Fumar.

    PubMed

    Pérez-Stable, E J; Marín, B V; Marín, G

    1993-01-01

    Background. Prevalence of cigarette smoking among Latinos compared to whites is higher among men (30.9% versus 27.9%), but lower among women (16.3% versus 23.5%). More acculturated Latina women, however, smoke more. Compared to other smokers, Latinos report consuming about half the average number of cigarettes per day. Up to a quarter of Latino smokers of less than 10 cigarettes per day may be underreporting consumption. The association between smoking and depression has also been found in Latinos. Program Goals. The Programa Latino Para Dejar de Fumar (Programa) goals are: 1) to evaluate attitudinal, behavioral, and cultural differences between Latino and white smokers; 2) to integrate these findings into a comprehensive, culturally-appropriate smoking cessation intervention; and 3) to implement the intervention in a defined community in order to decrease cigarette smoking prevalence, increase behaviors that may lead smokers to quit, and promote a nonsmoking environment. Program Components. Heightened concern about health effects of smoking, the importance of social smoking, and the influence of the family on behavior are integrated in the Programa components: 1) the promotion of a full-color, Spanish-language, self-help, smoking cessation guide (Guia), distributed at no charge; 2) an anti-smoking, Spanish-language, electronic media campaign; 3) community involvement; 4) quit smoking contests; 5) smoking cessation, individual, telephone consultations (consultas); and 6) collaboration with health care personnel. Results. Effectiveness of the Programa is being evaluated by annual, cross-sectional, random digit dialing telephone surveys compared to two baseline surveys. After 19 months of intervention, the proportion who had heard of the Programa increased from 18.5% to 44.0%, and over one third of less acculturated smokers had the Guia. Future directions will emphasize smoking prevention among youth, prevention of relapse among quitters, and depression prevention. PMID:10146254

    A partir de 1998, entrou em operação regular no INPE, em São José dos Campos, o Brazilian Solar Spectroscope (BSS). O BSS é dedicado às observações de explosões solares decimétricas com alta resolução temporal e espectral, com a principal finalidade de investigar fenômenos associados com a liberação de energia dos "flares" solares. Entre os anos de 1999 e 2002, foram catalogadas, aproximadamente 340 explosões solares classificadas em 8 tipos distintos, de acordo com suas características morfológicas. Na análise detalhada de cada tipo, ou grupo, de explosões solares deve-se considerar a variação do fluxo do sol calmo ("background"), em função da freqüência e a variação temporal, além da complexidade das explosões e estruturas finas registradas superpostas ao fundo variável. Com o intuito de realizar tal análise foi desenvolvido o programa BSSData. Este programa, desenvolvido em linguagem C++, é constituído de várias ferramentas que auxiliam no tratamento e análise dos dados registrados pelo BSS. Neste trabalho iremos abordar as ferramentas referentes à filtragem do ruído de fundo. As rotinas do BSSData para filtragem de ruído foram testadas nos diversos grupos de explosões solares ("dots", "fibra", "lace", "patch", "spikes", "tipo III" e "zebra") alcançando um bom resultado na diminuição do ruído de fundo e obtendo, em conseqüência, dados onde o sinal torna-se mais homogêneo ressaltando as áreas onde existem explosões solares e tornando mais precisas as determinações dos parâmetros observacionais de cada explosão. Estes resultados serão apresentados e discutidos.

    2009-01-01

    Objectives. We explored the emergence and effectiveness of Venezuela's Misión Barrio Adentro, “Inside the Neighborhood Mission,” a program designed to improve access to health care among underserved residents of the country, hoping to draw lessons to apply to future attempts to address acute health disparities. Methods. We conducted our study in 3 capital-region neighborhoods, 2 small cities, and 2 rural areas, combining systematic observations with interviews of 221 residents, 41 health professionals, and 28 government officials. We surveyed 177 female and 91 male heads of household. Results. Interviews suggested that Misión Barrio Adentro emerged from creative interactions between policymakers, clinicians, community workers, and residents, adopting flexible, problem-solving strategies. In addition, data indicated that egalitarian physician–patient relationships and the direct involvement of local health committees overcame distrust and generated popular support for the program. Media and opposition antagonism complicated physicians’ lives and clinical practices but heightened the program's visibility. Conclusions. Top-down and bottom-up efforts are less effective than “horizontal” collaborations between professionals and residents in underserved communities. Direct, local involvement can generate creative and dynamic efforts to address acute health disparities in these areas. PMID:19150916

    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.

    This paper describes the Venezuelan health system, including its structure and coverage, financial sources, human and material resources and its stewardship functions. This system comprises a public and a private sector. The public sector includes the Ministry of Popular Power for Health (MS) and several social security institutions, salient among them the Venezuelan Institute for Social Security (IVSS). The MH is financed with federal, state and county contributions. The IVSS is financed with employer, employee and government contributions. These two agencies provide services in their own facilities. The private sector includes providers offering services on an out-of-pocket basis and private insurance companies. The Venezuelan health system is undergoing a process of reform since the adoption of the 1999 Constitution which calls for the establishment of a national public health system. The reform process is now headed by the Barrio Adentro program. PMID:21877092

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.

    La Oficina del Estudio Geologico de los Estados Unidos (U.S. Geological Survey, 0 USGS) ha monitoreado la calidad del agua de la cuenca del Rio Grande (Rio Bravo del Norte) desde 1995 como parte de la rediseiiada Red Nacional para Contabilizar la Calidad del Agua de los Rios (National Stream Quality Accounting Network, o NASOAN) (Hooper and others, 1997). 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.

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

    PubMed

    Downward, Stuart R; Taylor, Ros

    2007-01-01

    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.

    Chandra-Mouli, Venkatraman; Gibbs, Susannah; Badiani, Rita; Quinhas, Fernandes; Svanemyr, Joar

    2015-01-01

    Adolescent sexual and reproductive health gained particular traction in Mozambique following the 1994 International Conference on Population and Development leading to the inception of Programa Geração Biz (PGB), a multi-sectoral initiative that was piloted starting in 1999 and fully scaled-up to all provinces by 2007. We conducted a systematic review of the literature to gather information on PGB and analyzed how it planned and managed the scale-up effort using the WHO-ExpandNet framework. PGB's activities comprised a clear and credible innovation. Appropriate resource and user organizations further facilitated national scale-up. Challenges relating to the complex nature of the multi-sectoral approach and resistance due to norms about adolescent sexual and reproductive health hindered scaling-up in some geographic areas. The national government exhibited commitment and ownership to PGB through budgetary support and integration into multiple policies. This study adds to the documentation of successful scaling-up strategies that can provide guidance for policy makers and programme managers. PMID:25971669

    Objective Little is known about the nature of the frailty syndrome in older Hispanics who are projected to be the largest minority older population by 2050. We examined prospectively the relationship between medical, psychosocial and neighborhood factors and increasing frailty in a community-dwelling sample of Mexican Americans over the age of 75. Method Based on a modified version of the Cardiovascular Health Study frailty index, we examined two-year follow up data from the Hispanic Established Populations for Epidemiologic Studies of the Elderly (H-EPESE) to ascertain the rates and determinants of increasing frailty among 2,069 Mexican American adults 75+ years of age at baseline. Results Respondents at risk of increasing frailty lived in a less ethnically dense Mexican-American neighborhood, were older, did not have private insurance or Medicare, had higher levels of medical conditions, had lower levels of cognitive functioning, and reported less positive affect. Discussion Personal as well as neighborhood characteristics confer protective effects on individual health in this representative, well characterized sample of older Mexican Americans. Potential mechanisms that may be implicated in the protective effect of ethnically homogenous communities are discussed. PMID:21948774

    The selection of vertebrate hosts by Culex mosquitoes relative to West Nile virus (WNV) transmission in neotropical countries such as Guatemala is not described. This study determined the feeding patterns of Cx. quinquefasciatus and Cx. nigripalpus and estimated the relative contribution of two common and frequently infected wild bird species, Turdus grayi and Quiscalus mexicanus, to WNV transmission. Engorged mosquitoes were collected from rural and urban habitats after the dry and wet seasons in the Department of Izabal in 2007. Host selection by Cx. nigripalpus varied significantly between urban and rural habitats. Both Cx. quinquefasciatus and Cx. nigripalpus fed predominantly on chickens and other domestic animals. Blood meals from wild birds were rare, accounting for 1.1% of blood meals identified from Cx. quinquefasciatus and 6.5% of blood meals from Cx. nigripalpus. Transmission of WNV by these two mosquito species may be dampened by extensive feeding on reservoir-incompetent hosts. PMID:23208881

    2013-01-01

    Objective Analysing health conditions in the town of Carirubana in Falcón State, Venezuela, as a prior study to the construction of a gas conditioning plant there. Methods This study formed part of a field research project which involved consulting primary and secondary sources. The former consisted of evaluating public and private health-centres and those in the Barrio Adentro system; the aforementioned health centres' medical staff were interviewed to determine current health-disease status and the factors determining health for the town being studied. Likewise, both situations (health-disease and factors determining health) were evaluated and analysed in the secondary sources at national, state and municipal level. Results Deficits were observed at national level regarding public health infrastructure; there were 1.3 beds per thousand inhabitants, this being less than half that recommended by the World Health Organization (WHO) (i.e. three to four beds per thousand inhabitants). State and municipal cancer mortality rates were relatively stable over a four-year period (2001-2004). Conclusions The mortality rate in Carirubana was characteristic of a low-income area. The poverty and pollution directly produced by the oil refining plants were the key determinants for this town's morbidity and mortality rates. PMID:25124249

    2014-01-01

    The California-Arizona Minority Partnership for Astronomy Research and Education (CAMPARE) program represents a new and innovative kind of research program for undergraduates: one that can effectively carry out the goal of recruiting qualified minority and female students to participate in Astronomy and Planetary Science research opportunities, while mentoring them in a way to maximize the chance that these students will persist in obtaining their undergraduate degrees in STEM fields, and potentially go on to obtain their PhDs or pursue careers in those fields. The members of CAMPARE comprise a network of comprehensive universities and community colleges in Southern California and Arizona (most of which are minority serving institutions), and four major research institutions (University of Arizona Steward Observatory, the SETI Institute, and JPL/Caltech). Most undergraduate research programs focus on a single research institution. By having multiple institutions, we significantly broaden the opportunities for students, both in terms of breadth of research topics and geographical location.

  13. Australia's Imported Food Program--a valuable source of information on micro-organisms in foods.

    PubMed

    Bull, Ann L; Crerar, Scott K; Beers, Mary Y

    2002-01-01

    Foods imported into Australia are subject to laboratory testing for microbiological and chemical hazards under the Imported Food Program (IFP) for the purposes of protecting public health and safety. The program, operating under the Imported Food Control Act 1992, is jointly administered by the Australian Quarantine Inspection Service (AQIS) and the Australia New Zealand Food Authority (ANZFA). Foods that fail under the IFP are subsequently subjected to appropriate treatment to rectify the problem, or are destroyed or re-exported. This article presents a limited analysis of IFP test results on selected foods imported between 1995 and 1999. As corrective action is taken immediately on the basis of failing test results, regular analysis of collated data is not considered a priority. Nonetheless these data potentially represent an important source of information on the nature of food microorganisms detected in imported foods. For example, IFP data could be used to focus local and state-based food surveillance efforts, provide information to importers, to inform national initiatives such as OzFoodNet, and to better target investigative and preventative efforts concerning foodborne illness.

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

    NASA Astrophysics Data System (ADS)

    Lopez Ortiz, Wilma J.

    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.

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

    NASA Astrophysics Data System (ADS)

    Reinartz-Estrada, Monica

    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.

    2001-09-01

    We examined the effect of smoking cessation on natural killer (NK) activity of peripheral blood lymphocytes in terms of a prospective study of 27 Japanese subjects who participated in a smoking cessation intervention program. This program was delivered by means of group-counseling offering 7 sessions of about 2 hours over 6 months to help smokers to discontinue the habit. Thirteen subjects ceased smoking (quitters), while 14 continued to smoke (cigarette smokers). NK activity before the intervention was correlated positively with age (correlation coefficient=0.46, P<0.05). NK activity remained almost constant among quitters, comparing the activity before and after the intervention, while it decreased among cigarette smokers although it was not statistically significant. In the subgroup analysis, NK activity increased among those aged less than 65 years, or urine cotinine levels over 800 ng/ml before the intervention, especially among quitters, but there were no statistical significances. Multiple regression analysis showed changes in NK activity were correlated significantly only with age (standard regression coefficient=-0.44, P<0.05). These findings suggest that smoking cessation intervention programs might have been more effective for younger than elder subjects in consideration of NK activity. PMID:11579933

    The present study explores the experience obtained with the Lippes Loops C and D in the family planning program of the Secretaria de Salubridad y Asistencia (Ministry of Health) of Mexico. The patterns observed are sufficiently similar to those reported for the majority of other countries for which data are available that it would appear that no special conditions affecting use of this method exist in Mexico. The study is viewed as having utility for practicing physicians as it provides information on relative frequency of temporary and definitive use terminations, relative frequency of method failure, expulsion, withdrawals for various reasons, and the specific groups of women most disposed to each type of event. The variables studied in this representative sample of acceptors are duration of method use, number of pregnancies prior to acceptance, number of children living, age, and educational level.

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

    NASA Astrophysics Data System (ADS)

    Teatini, Pietro; Baú, Domenico; Gambolati, Giuseppe

    2000-09-01

    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 compactación en profundidad tendrá un efecto en superficie. Con el objeto de estudiar la incertidumbre de unos pocos parámetros hidromecánicos fundamentales, se simularon diversos escenarios y se obtuvieron las predicciones más pesimistas. Los resultados numéricos muestran que, como máximo, se puede esperar una subsidencia de 1 cm en la ciudad de Chioggia al cabo de 25 años, mientras que no afectará a la ciudad de Venecia. Si se contrarresta el descenso de los niveles mediante inyecció de agua, se podrá limitar la subsidencia a un radio de 5 km mar adentro y propiciar un aumento de 0,6 a 0,7 cm en la costa de Chioggia.

    Aquaculture is anticipated to be a critical element in future solutions to global food shortage. However, diseases can impede industry efficiency and sustainability. Consequently, diseases can and have led to dramatic re-structuring in industry or regulatory practices. The emergence of infectious salmon anemia (ISA) in Chile is one such example. As in other countries, many mitigations were instituted universally, and many incurred considerable costs as they introduced a new layer of coordination of farming activities of marine sites within common geographic areas (termed 'neighborhoods' or 'barrios'). The aggregate response led to a strong reduction in ISA incidence and impact. However, the relative value of individual mitigations is less clear, especially where response policies were universally applied and retrospective analyses are missing 'controls' (i.e., areas where a mitigation was not applied). Further, re-focusing policies around disease prevention following resolution of an outbreak is important to renew sustainable production; though, again, field data to guide this shift in purpose are often lacking. Expert panels can offer timely decision support in the absence of empirical data. We convened a panel of fish health experts to weight risk factors predictive of ISA virus (ISAV) introduction or spread between Atlantic salmon barrios in Chile. Barrios, rather than sites, were the unit of interest because many of the new mitigations operate at this level and few available studies examine their efficacy. Panelists identified barrio processing plant biosecurity, fallowing strategies, adult live fish transfers, fish and site density, smolt quality, hydrographic connection with other neighborhoods, presence of sea lice (Caligus rogercresseyi), and harvest vessel biosecurity as factors with the greatest predictive strength for ISAV virulent genotype ('HPR-deleted') occurrence. Fewer factors were considered predictive of ISAV HPR0 genotype ('HPR0') occurrence, with greatest strengths assigned to fish and site density, adult live fish transfers, and smolt facility HPR0 status. Field validation based on ISAV and risk factor occurrence after panel completion generally supports expert estimates, and highlights a few factors (e.g., broodstock HPR0 status) less conclusive in the original study. Results inform legislation, industry best management practices and surveillance design. PMID:25304178

    2006-10-01

    This paper focuses on risk, conceived not as an individual action, but considering its social dimension, analyzing the various forms in the socio-cultural context related to internalized homophobia and hegemonic gender norms that allow barriers to be constructed in risk perception. Such barriers hinder negotiation and protection among homosexual men that have adopted a female gender identity, living in low-income barrios of Lima and Trujillo, Peru. Risk perception is analyzed on the socio-cultural plane, allowing one to explain the limited negotiating capacity of this population, even though they have extensive knowledge of HIV/AIDS and its consequences.

  8. Hilots make the family planning scene.

    PubMed

    1974-10-01

    A hilot (birth attendant), Aling Melchora, of Roxas, Oriental Mindora, who does motivation work in family planning is typical of hilots who are found in every barrio throughout the Philippines. She is 58 years old and has been a hilot for more than 30 years. She learned birth attendance in a training course at the Pandacan Puericulture Center in 1940. She averages 3 deliveries a month and 8 IUD acceptances a month. The hilots are a possible strong force in family planning motivation because of their influence and the respect with which people in the community regard them. They are older, experienced, always available, and charge very reasonable rates for services highly trained clinic staff would balk at doing. The Institute of Maternal and Child Health (IMCH) has trained 400 such hilots to do motivation work in family planning. It is noted that in the Philippines, the hilot may yet provide the key to reach the people in the barrios, which is the most important and challenging task for the national program on family planning.

    Este folleto contiene historias veridicas que ilustran como sobrevivir, y como no sobrevivir, a un tsunami. Esta publicacion esta dirigida a las personas que viven, trabajan o, simplemente, se divierten a lo largo de las costas que pueden ser afectadas por un tsunami. Tales costas rodean la mayor parte del Oceano Pacifico pero tambien incluyen algunas areas costeras de los Oceanos Atlantico e Indico. Aunque mucha gente llama a los tsunamis 'olas de marea', estos no estan relacionados a las mareas, sino son una serie de olas, o 'tren de olas', generalmente causadas por cambios en el nivel del fondo marino durante los terremotos. Los tsunamis tambien pueden ser generados por la erupcion de volcanes costeros, islas volconicas, deslizamientos submarinos e impactos de grandes meteoritos en el mar. Como sucedio en Sumatra en el 2004, los tsunamis pueden alcanzar alturas de 15 metros, no tan solo en la costa sino tambien kilometros tierra adentro. Los relatos presentados en este folleto fueron seleccionados de entrevistas realizadas a personas que sobrevivieron al tsunami del Oceano Pacifico de 1960. Muchas de estas personas, incluyendo a la enfermera de la foto, se enfrento a las olas generadas a poca distancia, en la costa chilena. En cambio, otros debieron hacer frente al tsunami muchas horas despues, en Hawai y Japon. La mayoria de las entrevistas fueron realizadas a fines de los anos ochenta y en los noventa. Las historias ofrecen una mezcla de lecciones de supervivencia a un tsunami. En algunos casos se presentan las acciones que confiablemente salvaron vidas: poner atencion a los avisos de la naturaleza, abandonar los bienes, dirigirse rapidamente a un sector alto y permanecer alli hasta que el tsunami realmente haya terminado. Otras historias describen como se encontro refugio al subir a construcciones y arboles o flotar sobre desechos, tacticas que tuvieron diferentes resultados y que pueden ser recomendadas solo como actos desesperados de personas atrapadas en sectores bajos.

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

    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.

  15. The hyperfine excitation of OH radicals by He

    2016-04-01

    Hyperfine-resolved collisions between OH radicals and He atoms are investigated using quantum scattering calculations and the most recent ab initio potential energy surface, which explicitly takes into account the OH vibrational motion. Such collisions play an important role in astrophysics, in particular in the modelling of OH masers. The hyperfine-resolved collision cross sections are calculated for collision energies up to 2500 cm-1 from the nuclear spin free scattering S-matrices using a recoupling technique. The collisional hyperfine propensities observed are discussed. As expected, the results from our work suggest that there is a propensity for collisions with ΔF = Δj. The new OH-He hyperfine cross sections are expected to significantly help in the modelling of OH masers from current and future astronomical observations.

    For the asymmetric spherical dimer of an endohedrally confined atom and a host fullerene, an innershell vacancy of either system can decay through the continuum of an outer electron hybridized between the systems. Such decays, viewed as coherent superpositions of the single-center Auger and two-center inter-Coulombic (ICD) amplitudes, are found to govern leading decay mechanisms in noble-gas endofullerenes, and are likely omnipresent in this class of nanomolecules. A comparison between resulting autoionizing resonances calculated in the photoionization of Ar@C60 and Kr@C60 exhibits details of the underlying processes.

    2014-01-01

    Lutzomyia longipalpis was recorded for the first time in Argentina in 2004, in the province of Formosa. In the following years, the vector spread to the south and west in the country and was recorded in the province of Chaco in 2010. From November 2010-May 2012, captures of Phlebotominae were made in the city of Resistencia and its surroundings, to monitor the spread and possible colonisation of Lu. longipalpis in the province of Chaco. In this monitoring, Lu. longipalpis was absent in urban sampling sites and its presence was restricted to Barrio de los Pescadores. This suggests that the incipient colonisation observed in 2010 was not followed by continuous installation of vector populations and expansion of their spatial distribution as in other urban centres of Argentina.

    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-Villazn, 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 Villazn 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 Villazn, 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

    Water shortages have resulted from agricultural development in a rural area outside Bogota, Colombia. These shortages have increased women's work load and caused problems in managing households because the water must be boiled before ingestion. In the community of Funza, women must obtain clean water in buckets at night from the main valve, which has insufficient water pressure and a slow stream. Some barrios collect water on a weekly basis. The local restaurant in town obtains water once a week from a tanker; the town is lucky to receive water three times a week. Men assume that women will take care of the problem. The mayor says that the piped water from Bogota will soon be connected and that each barrio will have its own valve. Women are concerned that the supply, even with new valves, will be limited and mixed with dirty lagoon water. Experts are saying that the water shortage and quality problems that began seven years ago will lead to rationing within three to six years. The flower companies, that came to the area 22 years age, are blamed for the water problems. People say that the flower companies have piped clean water from the area's supply in the San Patricia and that underground sources of water have been used up as well. The industry provides jobs and income, which have improved the standard of living, but there is little consideration given to the water supply. The community shifted water sources to the lagoon at a time when the water was being contaminated by sewage and pesticides and chemicals from the flower companies. PMID:12287011

    NASA Astrophysics Data System (ADS)

    Rey, J.; Martínez, J.; Hidalgo, M. C.

    2013-09-01

    A geophysical survey has been conducted on the lowest terrace levels and the present day floodplain of the current course of the Guadalquivir River, passing through the province of Jaen (Spain), using two techniques: electrical resistivity imaging (ERI) and ground-penetrating radar (GPR). Three areas have been selected. In one of these sectors (Los Barrios) there is an old quarry where there are excellent outcrops that allow for the calibration of the survey techniques. Facies associations on these outcrops are typical of meandering rivers with sequences of channel fills, lateral accretion of point-bars and floodplain facies. The usefulness of the two methods is analysed and compared as a support for stratigraphic and sedimentological studies. The geometry and lithofacies of subsurface deposits were characterised using ERI and compared with field observations. A total of 5 electrical resistivity imaging profiles were obtained. The changes in electric resistivity highlight granulometric differences in terrace sediments. This technique can thus be used to identify the morphology of these bodies, the lithofacies (silt, sand or gravel) and buried channel pattern. In addition, 16 GPR profiles using 100 and 250 MHz antennas were acquired, indicating terrace morphology and the filling of the sedimentary bodies in a more detailed manner than in ERI. The study thus allows for inferring the existence of channel migration, the lateral accretion of point bars and the presence of vertical accretion deposits attributable to the floodplains.

  13. Hydrogenated pyrene: Statistical single-carbon loss below the knockout threshold

    2016-04-01

    An ongoing discussion revolves around the question of what effect hydrogenation has on carbon backbone fragmentation in polycyclic aromatic hydrocarbons (PAHs). In order to shed more light on this issue, we have measured absolute single carbon loss cross sections in collisions between native or hydrogenated pyrene cations (C16H+10+m, m = 0, 6, 16) and He as functions of center-of-mass energies down to 20 eV. Classical molecular dynamics (MD) simulations give further insight into energy transfer processes and also yield m-dependent threshold energies for prompt (femtoseconds) carbon knockout. Such fast, non-statistical fragmentation processes dominate CHx-loss for native pyrene (m = 0), while much slower statistical fragmentation processes contribute significantly to single-carbon loss for the hydrogenated molecules (m = 6 and m = 16). The latter is shown by measurements of large CHx-loss cross sections far below the MD knockout thresholds for C16H+16 and C16H+26.

    2013-01-01

    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.

  16. Abbreviated measures of food sufficiency validly estimate the food security level of poor households: measuring household food security.

    PubMed

    Lorenzana, P A; Sanjur, D

    1999-03-01

    This study was designed to develop an abbreviated method that captures both the qualitative and quantitative dimensions of household food security (HFS). Women in poor and very poor households (n = 238) in a peri-urban barrio in Caracas, Venezuela, provided data on food availability and their perception of food resource constraints and hunger experiences within the home. Socioeconomic data and food-related behavior that may predict HFS levels were gathered. On average, the top 12 food contributors of energy provided 81% and predicted more than 90% of the variation in households' total energy availability using stepwise regression analysis. On the other hand, a 4-point 12-item scale was shown to have face, content and construct validity with reiterative testing, factor analysis and a Chronbach's alpha coefficient of 0.92. Assessing predictors of energy availability together with a self-perceived HFS scale may provide a valid and reliable method for identifying and monitoring food security levels among poor urban households.

    The Dominican Republic is one of four remaining countries in the Americas with lymphatic filariasis (LF). Annual mass drug administration (MDA) with albendazole and diethylcarbamazine was conducted in La Ciénaga, an impoverished urban barrio in Santo Domingo, from 2004 to 2006. Eight years after the last MDA, a transmission assessment survey (TAS) was conducted in November-December 2014 to determine if LF transmission remains absent. Of 815 first and second grade primary school students (mean age: 6.51 years; range 5-9) tested by immunochromatographic test (ICT), zero (0.0%) were positive. This is below the TAS critical cutoff of nine, indicating that the area "passed" TAS and that transmission remains interrupted in La Ciénaga. Importantly, this also provides evidence that three rounds of effective (> 65% coverage) MDA, likely aided by environmental improvements and periodic school-based albendazole monotherapy MDA, achieved interruption of LF transmission from a relatively low-transmission setting.

    A food frequency survey of 254 low-income, elderly (aged 60 to 96), free-living Mexican Americans and non-Hispanic whites was conducted as part of a larger study of the adjustment and health of older persons residing in a San Antonio barrio. Weekly intakes of selected foods were determined using the food frequency questionnaire from the Hispanic Health and Nutrition Examination Survey. We used t-tests to determine significance of difference in frequency of food consumption by ethnicity. The variance in consumption of selected foods was estimated with multiple regression analysis for the independent variables marital status, age, sex, education level, income, birthplace, and ethnicity. Ethnicity was the major variable influencing food intake. There were significant differences (p less than or equal to .05) between ethnic groups: Mexican Americans consumed eggs, poultry, legumes, organ meats, avocados/olives, flour tortillas, and sugar more frequently than non-Hispanic whites; they also used saturated fats in cooking more frequently than non-Hispanic whites; and they consumed skim milk, ice cream/ice milk, beef, all fruits or juices, all vegetables, breads, and oil/margarine less frequently than non-Hispanic whites. The results suggest that ethnicity plays a major role in predicting dietary patterns. PMID:2131339

    The environmental justice movement has come a long way since its birth a decade ago in rural and mostly African American Warren County, North Carolina. The selection of Warren County for a PCB landfill, they brought national attention to waste facility siting inequities and galvanized African American church and civil rights leaders` support for environmental justice. The demonstrations also put {open_quotes}environmental racism{close_quotes} on the map and challenged the myth that African Americans are not concerned about or involved in environmental issues. Grassroots groups, after decades of struggle, have grown to become the core of the multi-issue, multiracial, and multi-regional environmental justice movement. Diverse community-based groups have begun to organize and link their struggles to issues of civil and human rights, land rights and sovereignty, cultural survival , racial and social justice, and sustainable development. The impetus for getting environmental justice on the nations`s agenda has come from an alliance of grassroots activists, civil rights leaders, and a few academicians who questioned the foundation of the current environmental protection paradigm--where communities of color receive unequal protection. Whether urban ghettos and barrios, rural {open_quotes}poverty pockets,{close_quotes} Native American reservations, or communities in the Third World, grassroots groups are demanding an end to unjust and nonsustainable environmental and development policies.

    The nexus between substance use and aggressive crime involves a complex interrelationship among mediating individual and community-level variables. Using multilevel logistic regression models, we investigate how community-level concentration of poverty variables mediate the predictive relationships among individual level social attachment variables and substance use on aggressive crime in a large national sample of male arrestees (N = 20,602) drawn from 24 U.S. urban areas. The findings support our hypothesis that individual social attachments to marriage and the labor force (education and employment) are the principal individual-level pathway mediating the substance abuse/aggression nexus. In the random intercept model, 3.17% of the variation not explained by the individual-level predictor variables is attributable to community-level variation in urban area female-headed households and households receiving welfare. This confirms our hypothesis that social structural conditions of an urban environment differentially expose persons to conditions that predict being arrested for an aggressive crime. Our findings tend to counter the cultural theorists who argue for an indigenous culture of violence in inner-city ghettos and barrios. PMID:17668345

    AID's overall evaluation of its Philippine Rural Electrification (RE) program, consisting of eight successive projects, had limited effect on the rural poor and the economic development process. This program began in 1965 and has since energized 844 (59% of the national total) Philippine municipalities, 9088 (27%) barrios, 1,159,434 (20%) households, and 101 new cooperatives; resulting in a change of schedule for total national energization from 1980 to 1987. To improve the productive capacity of the poor, cooperatives were organized and lent funds to extend electrical power into their areas. Many of the poor, however, could not afford its installation, continued use, or more than one or two light bulbs a month. Community lighting, such as street-lighting, indirectly helped the poor in various ways, such as by providing greater personal security. Those with sufficient financial resources or skills were able to use the electricity for entrepreneurial activities. RE impact upon development occurred in areas with a concentrated population, available technical skills and capital, and access to large and diverse markets. Active promotion of electricity-dependent investments and projects also increased program impact.

    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.

    Emissions of SO2 and NO2 from coal-fired power plants are a significant source of air pollution. In order to typify the power plants' plumes dynamics and quantify their contribution to air quality, a comprehensive characterisation of seven coal-fired power plant plumes has been performed under six representative circulation types (CTs) identified by means of a synoptic classification over the Iberian Peninsula. The emission and the transport of SO2 and NO2 have been simulated with the CALIOPE air quality forecasting system that couples the HERMES emission model for Spain and WRF and CMAQ models. For the facilities located in continental and Atlantic areas (As Pontes, Aboño, and Compostilla) the synoptic advection controls pollutant transport, however for power plants located along the Mediterranean or over complex-terrains (Guardo, Andorra, Carboneras, and Los Barrios), plume dynamics are driven by a combination of synoptic and mesoscale mountain-valley and sea-land breezes. The contribution of power plants to surface concentration occurs mainly close to the source (<20 km) related to a fumigation process when the emission injection takes place within the planetary boundary layer reaching up to 55 μg SO2 m(-3) and 32 μg NO2 m(-3). However, the SO2 and NO2 plumes can reach long distances (>250 km from the sources) especially for CTs characterised by Atlantic advection. PMID:26433330

    The high rate of urbanization, political conflicts and ensuing internal displacement of population, and increased poverty in the 20th century has resulted in rapid increase of informal settlements. These unplanned, unauthorized, and/or unstructured homes, known as informal settlements, shantytowns, barrios, or slums, pose several challenges to the nations, as these settlements are often located in most hazardous regions and lack basic services. Though several World Bank and United Nations sponsored studies stress the importance of poverty maps in designing better policies and interventions, mapping slums of the world is a daunting and challenging task. In this paper, we summarize our ongoing research on settlement mapping through the utilization of Very high resolution (VHR) remote sensing imagery. Most existing approaches used to classify VHR images are single instance (or pixel-based) learning algorithms, which are inadequate for analyzing VHR imagery, as single pixels do not contain sufficient contextual information (see Figure 1). However, much needed spatial contextual information can be captured via feature extraction and/or through newer machine learning algorithms in order to extract complex spatial patterns that distinguish informal settlements from formal ones. In recent years, we made significant progress in advancing the state of art in both directions. This paper summarizes these results.

    Introducción: la población saharaui residente en los campamentos de Tinduf (Argelia) se considera vulnerable desde el punto de vista nutricional.Objetivos: evaluar los hábitos dietéticos de un grupo de mujeres emigrantes saharauis con el fin de obtener datos para diseñar un programa de educación nutricional (EN) destinado a mujeres residentes en los campamentos.Métodos: la información sobre hábitos dietéticos se registró a través de historias dietéticas. Los resultados de ingesta de macro y micronutrientes se compararon con los rangos aceptables de distribución y los requerimientos medios estimados. También se recogieron datos demográficos, socioeconómicos y sobre salud. Análisis estadístico: SPSS vs 22.0. A partir de los datos obtenidos y de la revisión de los programas de salud llevados a cabo en campamentos y de otros programas de EN se diseñó un programa específico.Resultados: la alimentación en campamentos se caracterizó por ser deficitaria en energía y por un bajo consumo de fibra (6,1 [2,8] g/día), de ácidos grasos monoinsaturados (6,9 [2,9]% del valor calórico total) y de la mayoría de los micronutrientes. El aumento en la disponibilidad de alimentos tras emigrar a España incrementó la ingesta calórica, pero la dieta siguió siendo inadecuada. El programa de EN diseñado se basó en la formación de formadoras. En este manuscrito se proporciona información detallada sobre la organización y el material a emplear en esta intervención educativa.Discusión y conclusión: la alimentación de las mujeres saharauis en campamentos y tras emigrar a España fue inadecuada, lo que corrobora que la aculturación puede estar asociada a cambios no saludables. Cabe esperar que el programa de EN diseñado contribuya a mejorar su bienestar nutricional. PMID:27019252

    OBJECTIVE To understand the job function of caregivers of older adults and contribute to the debate on the consolidation of this professional practice. METHODOLOGICAL PROCEDURES This is a descriptive, qualitative, and exploratory study. Four focal group sessions were performed in 2011 with 11 elderly companions, formal caregivers of older adults in the Programa Acompanhante de Idosos (Program for Caregivers of Older Adults), Sao Paulo, SP, Southeastern Brazil. These sessions, guided by a semi-structured script, were audio-recorded and fully transcribed. Data were analyzed using the Content Analysis technique, Thematic Modality. RESULTS In view of considering the caregivers of older adults as a new category of workers, it was difficult to define their duties. The elderly companions themselves as well as the care receivers, their families, and the professionals that comprised the team were unclear about their duties. The professional practice of these formal caregivers has been built on the basis of constant discussions and negotiations among them and other team members in Programa Acompanhante de Idosos during daily work. This was achieved via a recognition process of their job functions and by setting apart other workers’ exclusive responsibilities. CONCLUSIONS The delimitation of specific job functions for elderly companions is currently one of the greatest challenges faced by these workers to develop and consolidate their professional role as well as improve Programa Acompanhante de Idosos.

    The phase diagram assessment of binary AMPL-TRIS system was calculated using the CALPHAD approach. Thermo-Calc, TCC software was used to fit the experimental phase diagram data by simultaneous optimization of thermodynamic properties of pure components and phase equilibria data available in the literature, and also calculated in the present work. The measured interaction parameters for low temperature alpha and beta solid solution phases are relatively small and are assumed to be ideal. Preliminary calculation of AMPL-TRIS phase diagram showed complete solid solubility of the high temperature gamma and gamma-prime phases, as reported by Barrio et al. (1994). In the next iteration, we calculated AMPL-TRIS phase diagram using heat capacity data and found that it was in good agreement with the current experimental phase diagram developed by V. Kamisetty (2010). In final calculations, the Parrot module of Thermo-Calc program was used to obtain an optimized phase diagram. The calculated phase corroborates well with V. Kamisetty data. Two eutectoids, one at ~21 mol.% TRIS at 85oC, the other at ~60 mol. % TRIS at 104oC, and one peritectic at 55 mol.% TRIS at 127oC were calculated. The maximum solubility of TRIS in AMPL is 10 mol.%, and that of AMPL in TRIS is 18 mol.% at 85oC. An important feature of this phase diagram is the presence of gamma and gamma-prime phases above 110oC. Details of the methodology and calculations are shown in this thesis.

    On 4 April 2011, as part of the XVIII Conference in Law and the Human Genome, the official presentation took place of the first Spanish language Encyclopedia of Biolaw and Bioethics, in an event organised by the Inter-University Chair in Law and the Human Genome held, on this occasion, in the new Auditorium of the University of the Basque Country. The Encyclopedia of Biolaw and Bioethics is a project which was conceived and driven forward by the Inter-University Chair in Law and the Human Genome. It was an ambitious project which was supported by the Roche Institute Foundation. It was therefore a magnum opus which began more than three years ago and which has required the work of more than 200 professionals from various disciplines in Spain, Latin America and Portugal. The encyclopaedia tries to make up for the lack of a suitable publication in the Spanish language that could be used as a reference and be consulted by different experts who have to tackle controversies and doubts posed in the field of biolaw and bioethics as part of their everyday work. The work makes it possible to ascertain the situation in this field regarding the most controversial issues and emerging conflicts, find out which values, assets or rights are involved or confronted, what solutions have been proposed by bioethics and the social positions that have been established through legal regulations. All in all, the encyclopaedia was the culmination of an ambitious undertaking, a pioneering work in the Spanish speaking countries due to its characteristics and scope. It is essential to have such a resource in today's cultural environment. The presentation of the Encyclopedia of Biolaw and Bioethics given by Mr. Del Barrio Seoane as Director General of the Roche Institute Foundation during the Conference deservers a special mention. The project has been consolidated through the support of this institution. PMID:22977954

    The effects of quantum confinement on the momentum distribution of electrons confined within a cylindrical potential well have been analyzed. The motivation is to understand specific features of the momentum distribution of electrons when the electron behavior is completely controlled by the parameters of a non-isotropic potential cavity. It is shown that studying the solutions of the wave equation for an electron confined in a cylindrical potential well offers the possibility to analyze the confinement behavior of an electron executing one- or two-dimensional motion in the three-dimensional space within the framework of the same mathematical model. Some low-lying electronic states with different symmetries have been considered and the corresponding wave functions have been calculated; the behavior of their nodes and their peak positions with respect to the parameters of the cylindrical well has been analyzed. Additionally, the momentum distributions of electrons in these states have been calculated. The limiting cases of the ratio of the cylinder length H and its radius R0 have been considered; when the cylinder length H significantly exceeds its radius R0 and when the cylinder radius is much greater than its length. The cylindrical quantum confinement effects on the momentum distribution of electrons in these potential wells have been analyzed. The possible application of the results obtained here for the description of the general features in the behavior of electrons in nanowires with metallic type of conductivity (or nanotubes) and ultrathin epitaxial films (or graphene sheets) are discussed. Possible experiments are suggested where the quantum confinement can be manifested.

    The interaction of biological molecules like chiral amino acids with chiral metal clusters is becoming an interesting and active field of research because of its potential impact in, for example, chiral molecular recognition phenomena. In particular, the enantiospecific adsorption (EA) of cysteine (Cys) on a chiral Au55 cluster was theoretically predicted a few years ago. In this work, we present theoretical results, based on density functional theory, of the EA of non-zwitterionic cysteine interacting with the C3-Au34 chiral cluster, which has been experimentally detected in gas phase, using trapped ion electron diffraction. Our results show that, indeed, the adsorption energy of the amino acid depends on which enantiomers participate in the formation Cys-Au34 chiral complex. EA was obtained in the adsorption modes where both the thiol, and the thiol-amino functional groups of Cys are adsorbed on low-coordinated sites of the metal cluster surface. Similarly to what was obtained for the Cys-Au55 chiral complex, in the present work, it is found that the EA is originated from the different strength and location of the bond between the COOH functional group and surface Au atoms of the Au34 chiral cluster. Calculations of the vibrational spectrum for the different Cys-Au34 diastereomeric complexes predict the existence of a vibro-enantiospecific effect, indicating that the vibrational frequencies of the adsorbed amino acid depend on its handedness.

    We report calculated electron impact ionization cross sections (EICSs) of beryllium-tungsten clusters, BenW with n = 1,...,12, from the ionization threshold to 10 keV using the Deutsch-Märk (DM) and the binary-encounter-Bethe (BEB) formalisms. The positions of the maxima of DM and BEB cross sections are mostly close to each other. The DM cross sections are more sensitive with respect to the cluster size. For the clusters smaller than Be4W they yield smaller cross sections than BEB and vice versa larger cross sections than BEB for clusters larger than Be6W. The maximum cross section values for the singlet-spin groundstate clusters range from 7.0 × 10-16 cm2 at 28 eV (BeW) to 54.2 × 10-16 cm2 at 43 eV (Be12W) for the DM cross sections and from 13.5 × 10-16 cm2 at 43 eV (BeW) to 38.9 × 10-16 cm2 at 43 eV (Be12W) for the BEB cross sections. Differences of the EICSs in different isomers and between singlet and triplet states are also explored. Both the DM and BEB cross sections could be fitted perfectly to a simple expression used in modeling and simulation codes in the framework of nuclear fusion research.

    The present work is concerned with the reaction of the hydroperoxyl radical with ozone, which is key in the atmosphere. We first give a brief overview which emphasizes theoretical work developed at the authors' Group, considering not only the naked reaction (n = 0) but also the reaction with one water molecule added to the reactants (n = 1). Aiming at a broad and contextual understanding of the role of water, we have also very recently published the results of the investigation considering the addition of water dimers (n = 2) and trimers (n = 3) to the reactants. Such results are also succinctly addressed before we present our latest and unpublished research endeavors. These consist of two items: the first one addresses a new mechanistic pathway for hydrogen-abstraction in n = 2-4 cases, in which we observe a Grotthuss-like hydrogen shuttling mechanism that interconverts covalent and hydrogen bonds (water molecules are no longer spectators); the second addresses our exploratory calculations of the HO2 + O3 reaction inside a (H2O)20 water cage, where we strive to give a detailed insight of the molecular processes behind the uptake of gas-phase molecules by a water droplet.

    We assessed current and historic land use and land cover in the Luquillo Mountains and surrounding area in eastern Puerto Rico, including four small subwatersheds that are study watersheds of the U.S. Geological Survey's Water, Energy, and Biogeochemical Budgets (WEBB) program. This region occupies an area of 1,616 square kilometers, about 18 percent of the total land in Puerto Rico. Closed forests occupy about 37 percent of the area, woodlands and shrublands 7 percent, nonforest vegetation 43 percent, urban development 10 percent, and water and natural barrens total less than 2 percent. The area has been classified into three main land-use categories by integrating recent census information (population density per barrio in the year 2000) with satellite image analyses (degree of developed area versus natural land cover). Urban land use (in this analysis, land with more than 20 percent developed cover within a 1-square-kilometer area and population density greater than 500 people per square kilometer) covered 16 percent of eastern Puerto Rico. Suburban land use (more than 80 percent natural land cover, more than 500 people per square kilometer, and primarily residential) covers 50 percent of the area. Rural land use (more than 80 percent natural land cover, less than 500 people per square kilometer, and primarily active or abandoned agricultural, wetland, steep slope, or protected conservation areas) covered 34 percent of the area. Our analysis of land-cover change indicates that in the 1990s, forest cover increased at the expense of woodlands and grasslands. Urban development increased by 16 percent during that time. The most pronounced change in the last seven decades has been the shift from a nonforested to a forested landscape and the intensification of the ring of urbanization that surrounds the long-protected Luquillo Experimental Forest.

    Recently, Physalaemus albifrons (Spix, 1824) was relocated from the Physalaemus cuvieri group to the same group as Physalaemus biligonigerus (Cope, 1861), Physalaemus marmoratus (Reinhardt & Lütken, 1862) and Physalaemus santafecinus Barrio, 1965. To contribute to the analysis of this proposition, we studied the karyotypes of Physalaemus albifrons, Physalaemus santafecinus and three species of the Physalaemus cuvieri group. The karyotype of Physalaemus santafecinus was found to be very similar to those of Physalaemus biligonigerus and Physalaemus marmoratus, which were previously described. A remarkable characteristic that these three species share is a conspicuous C-band that extends from the pericentromeric region almost to the telomere in the short arm of chromosome 3. This characteristic is not present in the Physalaemus albifrons karyotype and could be a synapomorphy of Physalaemus biligonigerus, Physalaemus marmoratus and Physalaemus santafecinus. The karyotype of Physalaemus santafecinus is also similar to those of Physalaemus marmoratus and Physalaemus biligonigerus owing to the presence of several terminal C-bands and the distal localization of the NOR in a small metacentric chromosome. In contrast, the Physalaemus albifrons karyotype has no terminal C-bands and its NOR is located interstitially in the long arm of submetacentric chromosome 8. The NOR-bearing chromosome of Physalaemus albifrons very closely resembles those found in Physalaemus albonotatus (Steindachner, 1864), Physalaemus cuqui Lobo, 1993 and some populations of Physalaemus cuvieri Fitzinger, 1826. Additionally, the Physalaemus albifrons karyotype has an interstitial C-band in chromosome 5 that has been exclusively observed in species of the Physalaemus cuvieri group. Therefore, we were not able to identify any chromosomal feature that supports the reallocation of Physalaemus albifrons. PMID:25147623

    The management of the contralateral hip after unilateral slipped capital femoral epiphysis (SCFE) is controversial. The aims of this study were to assess the interobserver and intraobserver reliability of the posterior sloping angle (PSA) as described by Barrios et al (J Pediatr Orthop. 2005;25:445-449) and whether it can be used as a predictor of need for prophylactic pinning of the contralateral hip. The PSA was measured by 4 different surgeons on 2 separated occasions in 47 unaffected contralateral hips after unilateral SCFE. The interobserver intraclass correlation coefficient (ICC) was 0.83 (excellent) for the first set of measurements and 0.74 (fair to good) for the second set of measurements. Measurement of the intraobserver ICC revealed an excellent agreement (ICC > 0.75) in 3 of the 4 surgeons and fair to good agreement in 1 of the surgeons (ICC between 0.4 and 0.74). Comparison of the PSA measurements of the first author (M.Z.) with a control group of 20 hips revealed that the PSA was significantly higher (P < 0.05) in the group of patients that eventually had a contralateral slip when compared with the PSA of patients in the study group who did not slip and with normal hips in the control group. Patients with contralateral SCFE that did not slip had a significantly higher PSA (P < 0.05) when compared with normal individuals. A PSA of 14.5 degrees or more is recommended for prophylactic pinning of the contralateral hip. The number needed to treat (NNT) at this cut off to avoid 1 future slip was calculated to be 1.9.

    It has long been known that some listeners experience hearing difficulties out of proportion with their audiometric losses. Notably, some older adults as well as auditory neuropathy patients have temporal-processing and speech-in-noise intelligibility deficits not accountable for by elevated audiometric thresholds. The study of these hearing deficits has been revitalized by recent studies that show that auditory deafferentation comes with aging and can occur even in the absence of an audiometric loss. The present study builds on the stochastic undersampling principle proposed by Lopez-Poveda and Barrios (2013) to account for the perceptual effects of auditory deafferentation. Auditory threshold/duration functions were measured for broadband noises that were stochastically undersampled to various different degrees. Stimuli with and without undersampling were equated for overall energy in order to focus on the changes that undersampling elicited on the stimulus waveforms, and not on its effects on the overall stimulus energy. Stochastic undersampling impaired the detection of short sounds (<20 ms). The detection of long sounds (>50 ms) did not change or improved, depending on the degree of undersampling. The results for short sounds show that stochastic undersampling, and hence presumably deafferentation, can account for the steeper threshold/duration functions observed in auditory neuropathy patients and older adults with (near) normal audiometry. This suggests that deafferentation might be diagnosed using pure-tone audiometry with short tones. It further suggests that the auditory system of audiometrically normal older listeners might not be "slower than normal", as is commonly thought, but simply less well afferented. Finally, the results for both short and long sounds support the probabilistic theories of detectability that challenge the idea that auditory threshold occurs by integration of sound energy over time.

    Background Since 2007, Guatemala integrated STI clinical service with an HIV prevention model into four existing public health clinics to prevent HIV infection, known as the VICITS strategy. We present the first assessment of VICITS scale-up, retention, HIV and STI prevalence trends, and risk factors associated with HIV infection among Female Sex Workers (FSW) attending VICITS clinics in Guatemala. Methods Demographic, behavioral and clinical data were collected using a standardized form. Data was analyzed by year and health center. HIV and STI prevalence were estimated from routine visits. Retention was estimated as the percent of new users attending VICITS clinics who returned for at least one follow-up visit to any VICITS clinic within 12 months. Separate multivariate logistic regression models were conducted to investigate factors associated with HIV infection and program retention. Results During 20072011 5,682 FSW visited a VICITS clinic for the first-time. HIV prevalence varied from 0.4% to 5.8%, and chlamydia prevalence from 0% to 14.3%, across sites. Attending the Puerto Barrios clinic, having a current syphilis infection, working primarily on the street, and using the telephone or internet to contact clients were associated with HIV infection. The number of FSW accessing VICITS annually increased from 556 to 2,557 (361%) during the period. In 2011 retention varied across locations from 7.7% to 42.7%. Factors negatively impacting retention included current HIV diagnosis, having practiced sex work in another country, being born in Honduras, and attending Marco Antonio Foundation or Quetzaltenango clinic sites. Systematic time trends did not emerge, however 2008 and 2010 were characterized by reduced retention. Conclusions Our data show local differences in HIV prevalence and clinic attendance that can be used to prioritize prevention activities targeting FSW in Guatemala. VICITS achieved rapid scale-up; however, a better understanding of the causes of low return rates is urgently needed. PMID:25167141

    Abstract Recently, Physalaemus albifrons (Spix, 1824) was relocated from the Physalaemus cuvieri group to the same group as Physalaemus biligonigerus (Cope, 1861), Physalaemus marmoratus (Reinhardt & Lütken, 1862) and Physalaemus santafecinus Barrio, 1965. To contribute to the analysis of this proposition, we studied the karyotypes of Physalaemus albifrons, Physalaemus santafecinus and three species of the Physalaemus cuvieri group. The karyotype of Physalaemus santafecinus was found to be very similar to those of Physalaemus biligonigerus and Physalaemus marmoratus, which were previously described. A remarkable characteristic that these three species share is a conspicuous C-band that extends from the pericentromeric region almost to the telomere in the short arm of chromosome 3. This characteristic is not present in the Physalaemus albifrons karyotype and could be a synapomorphy of Physalaemus biligonigerus, Physalaemus marmoratus and Physalaemus santafecinus. The karyotype of Physalaemus santafecinus is also similar to those of Physalaemus marmoratus and Physalaemus biligonigerus owing to the presence of several terminal C-bands and the distal localization of the NOR in a small metacentric chromosome. In contrast, the Physalaemus albifrons karyotype has no terminal C-bands and its NOR is located interstitially in the long arm of submetacentric chromosome 8. The NOR-bearing chromosome of Physalaemus albifrons very closely resembles those found in Physalaemus albonotatus (Steindachner, 1864), Physalaemus cuqui Lobo, 1993 and some populations of Physalaemus cuvieri Fitzinger, 1826. Additionally, the Physalaemus albifrons karyotype has an interstitial C-band in chromosome 5 that has been exclusively observed in species of the Physalaemus cuvieri group. Therefore, we were not able to identify any chromosomal feature that supports the reallocation of Physalaemus albifrons. PMID:25147623

    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 .

    This paper investigates the impact of the Bolsa Famlia Program on the immunization of children from 0 to 6 years of age in Brazil and its regions. The Bolsa Famlia program is a conditional cash transfer program. One of its conditionalities is the compliance of children with the immunization schedule ordered by the Ministry of Health. The evaluation was performed using the Propensity Score Matching technique. We used data from a survey conducted in 2005 evaluating the program - Pesquisa de Avaliao de Impacto do Programa Bolsa Famlia. The main findings suggest that the Bolsa Famlia Program does not affect the immunization status of children. PMID:22729265

Katholieke Universiteit Leuven, Department of Experimental Laboratory Medicine, Herestraat 49, B-3000 Leuven, Belgium Nephropathia epidemica (NE), a mild form of haemorrhagic fever with renal syndrome, is a zoonotic disease caused by a Hanta virus called Puumala virus in Europe. Concern about this disease has increased in recent years due to the increase in the amount of reported cases. In 2005, 2007 and 2008 the number of infected cases surpassed 300 cases per 100000 inhabitants in Belgium, which was never observed before. NE incidence is closely related to environmental conditions. The main role in the virus transmission mechanism is played by the red bank vole (Myodes glareolus), a rodent species that is native in West European broad-leaved forests (BLF) and acts as the virus reservoir. Although the link between vegetation and NE in Belgium has been underlined repeatedly in recent research works, so far little has been done towards the exploration of remote sensing techniques for analyzing vegetation systems as an input in early warning systems. This study aims at determining whether observed NE occurrence pattern in Belgium can be connected to specific trends in BLF phenology parameters. Hence, phenology information was derived from time series of the MODIS Enhanced Vegetation Index (EVI) for the period 2000-2008 in 10 major BLF in southern Belgium. EVI values were calculated from the MOD09A1 dataset which provides an estimate of the surface spectral reflectance for bands 1-7 at 500 m resolution every 8 days. Based on our preliminary results, it is concluded that one of the most remarkable phenomena taking place in BLF is the gradual increase in length of the growing season in the 2000-2007 period. This is supported by international literature. Increasing growing seasons might contribute to an increase in the availability of resources to sustain large rodent populations and in the prolongation of optimal conditions for breeding. For most of the sampled sites, the years preceding peaks in NE cases (2005, 2008) were characterised by a late end of the growing season which coincides with warmer fall seasons. This research is part of a larger effort that aims at the incorporation of remotely sensed data in the prediction and monitoring of epidemiologic diseases.

    OBJECTIVE: To investigate whether environmental contamination occurred in the wake of hurricane Mitch (30-31 October 1998), we conducted a population-based cross-sectional household survey in the barrio of Istoca, Department of Choluteca, Honduras. The goals were to evaluate chemical contamination of potable water and the extent of human exposure to chemicals as a result of extensive flooding. METHODS: The survey consisted of an environmental exposure assessment, which included assaying water and soil samples for contaminants, and taking blood and urine samples from 45 adolescents aged 15-18 years. We also made a subjective questionnaire assessment of 155 households. FINDINGS: There was significant contamination of the soil in Istoca, but no water contamination in the aftermath of hurricane Mitch. The soil levels of chlopyrifos and parathion were 30- and 1000-times higher, respectively, than the Environmental Data Quality Level. However, the most striking finding was the detection of elevated levels of chlorinated and organophosphate pesticides in adolescents. Toxicological analyses of serum specimens showed that 51% of the samples had elevated levels of 1,1-dichloro-2,2-bis-(p-chlorophenyl) ethylene (p,p-DDE) (range, 1.16-96.9 ng/ml) (US reference mean = 3.5 ng/ml) in adults). Dieldrin levels > 0.2 ng/ml were also present in 23% of the serum specimens (serum levels of this analyte in US adolescents are < 0.2 ng/ml). Of 43 urine samples analysed for organophosphate metabolites, 18.6% contained diethyl phosphate (DEP) at levels which were greater that the reference mean of 6.45 micrograms/g creatinine. We also detected elevated levels of p-nitrophenol (p-NP) and of 3,5,6-trichloro-2-pyridinol (3,5,6-TCPY) in 91% and 42% of the samples, respectively. CONCLUSIONS: The elevated levels of chlorinated pesticides were surprising, since although these substances were banned in Honduras 15 years ago it appears that they are still being used in the country. Moreover, elevated levels of organophosphates were detected in the study adolescents even three weeks after the hurricane. Since these chemicals are usually cleared from the body quickly, our data suggest that the adolescents face an ongoing threat from pesticide exposure. PMID:11357206

Es sin embargo un importante hito que resume las contribuciones de las ciencias sociales y biomédicas al campo de la demografía.SummaryThe volume Family Planning and Population Programs is an indispensable book to demographers as well as to others concerned with population control. It is not without limitations because of its heterogeneous character, its lack of self-criticism, its failure to deal with the reliability and validity of KAP surveys, its unwarranted optimistic aura, and its failure to explore and consider alternatives to the basic assumptions and premises on which present family planning programs are based. It is, nevertheless, a landmark in its summarization of the contribution of the social and biomedical sciences to demographic engineering. PMID:21279790

    La educación médica transcurre en un campo complejo donde confluyen las escuelas y facultades de medicina con el Sistema Nacional de Salud (SNS). Los médicos que atienden a los pacientes en las clínicas y hospitales al mismo tiempo fungen como profesores de los alumnos de pregrado y posgrado, combinando sus actividades asistenciales con las académicas, lo que implica una tensión más o menos resuelta en la práctica diaria. De esta manera, en algunos hospitales se privilegia la enseñanza y en otros, la labor asistencial. Los médicos en formación deben cumplir con un programa académico prescrito por la universidad que deviene en un programa operativo cuando es compatibilizado con las tareas y ritmos de la dinámica hospitalaria. Se planean clases teóricas, rotaciones en los distintos servicios, sesiones generales y específicas, y los estudiantes se incorporan al orden jerárquico de la clínica desarrollando el aprendizaje situado.

    RESUMEN: En los últimos quince años diez paises han inaugurado programas nacionales de planeamiento familiar: India, Pakistán, Corea del Sur, Taiwan, Turquía, Malasia, Ceilán, Túez, la República Arabe Unida, y Marruecos. Otros paises, incluyendo Tailandia, Hong Kong, Singapur, Kenya, Barbados, Trinidad y los Estados Unidos, apoyan y/o estimulan actividades de planeamiento familiar. En la mayor parte de los casos la razón fundamental del programa ha sido que si la tasa de crecimiento poblacional disminuyera, aumentaría la tasa de crecimiento económico.Las metas de largo alcance, expresadas típicamente en términos de reducir las tasa.de de natalidad o de crecimiento, tienen su ejemplo en el propósito de Pakistán de reducir su tasa de crecimiento a 26 para 1970; el de Corea de reducir su tasa de natalidad a 20 para 1971; y el de India de reducir su tasa de natalidad a 25 para 1973.Los objectivos intermedios, que cubren diversos aspectos del pro grama, incluyen metas específicas para un determinado mes a año, considerando personal, la adquisición de anticonceptivos, y el número de usarios por método. Las metas específicas anuales de aceptantes de dispositivos intrauterinos (IUD), para Taiwán, Corea, Túnez, Pakistán e India, son comunes, tanto por la naturaleza del artefacto, como por la facilidad de medición de los que continúan utilizándolos. El programa de evaluación en Taiwán, que trata de medir por diversos medios los efectos inmediatos, mediatos y de largo plazo del programa de planeamiento familiar sirve de modelo. El propósito de la evaiuación de un programa de planeamiento familiar es contribuir a la efectividad y eficiencia del programa, midiendo y analizando su progreso. Las áreas a medir pueden ser clasificadas como- (1) conocimiento acerca de; (2) actitudes hacia; (3) práctica de control de natalidad; y (4) nivel de fecundidad.Un buen sistema de evaluación debería incluir: A. Un buen conjunto de estadísticas de servicio presentadas en formularios estandarizados, en las siguienies formas: 1. Informes nensuales por áreas administrativas, sobre los actuales servicios de planeamiento familiar proporcionados en la actualidad, de carácter permanente o de larga duración (al presente, esterilización y IUD de acuerdo a las siguientes características del receptor: residencia, edad, paridad (número de hijos vivos por sexo), y donde se enteró del programa, si es posible "clase";(probablemente educación de la madre, pero posiblemente ocupación del esposo, ingreso, o equivalente); prácticas anticonceptivas anteriores; intervalo; y deseo de tener más hijos. En un programa grande estos datos pueden obtenerse en base a una muestra. 2. Informes mensuales sobre la distribución de suministros anticonceptivos (condones, píldoras, sustancias efervescentes, etc.), los primeros suministros deben ir acompañados de un registro de las características del recipiente, como anteriormente; los suministros subsecuentes se regietrarán sólo en volumen bruto. Esto también se aplicará al ritmo, donde éste método se enseñe a un número considerable de mujeres. 3. Informes regulares sobre las actividades de planeamiento familiar de médicos privados, como una estimación del efecto catalítico del programa del gobierno sobre ci sector privado. 4. Datos generates mensuales, ppr áreas admirtistrativas importantes, sabre: visitas domiciliarias, reuniones, cuñas radiates y televisadas, avisos en los periódicos y personal que trabaja. 5. Para propósitos de seguimiento una entrevi eta de campo cada 6 a 12 meses a cada N mujer de las listas para (1) y (2) arriba, en un total de 300 o 400, para conocer las tasas de continuación y las razones de abandono (ej: desea otro hijo, insatisfecha can ci método, otras). Las mue.stras podrían ser de 300 cada una, con una supuesta experiencia de 6, 12, 18 y 24 meses. B. Un buen conjunto de datos sobre costa (datos sobre cotos actulaes atribuíbles directamente al programa de planeamiento familiar) fraccionados par áreas principales y cinco a seis categorías de costos importantes tales coma: adminietración, personal de campo, publicidad, suministros, etc. C. Un buen conjunto de dates globales sobre la distribución de los suministros comerciales que puedan llegar tan cerca como sea posible del último consumidor, to cual significa probablemente obtener información de los mayoristas. D. Una encuesta de conocimientos, actitudes y prácticas (KAP) para una evaluación general cada dos años. Las preguntas básicas (además de las antes mencionadas y estatus marital y étnico cuando sea pertinente) son: actitud hacia e interés por la anticoncepción, número de niños por sexo, deseo de tener más hijos, prácticas anticonceptivas, experiencia sobre abortos, tal vez historia de embarazo (especialmente si esta producirá una tasa de fecundidad válida), aprobación del programa gubernamental (para uso politico), y si está actualmente embarazada (la única y mejor pregunta cuya respuesta habla del efecto sobre la tasa de natalidad). Administrativamente, la responsabilidad por la evalucion debe estar cerca al director, se debe tomar provisiones para obtener informes regulares (meneulaes) y especiales dirigidos a preguntar sobre política. El corolario es que el jefe de evaluación debe tener la confianza del director y debe estar al día en cuanto a las decisiones sabre la politics a seguir. Su trabajo consiste en extractar los aspectos principales que funcionan bien y los no operantes. En cuanto a costos, la evaluación debe hacerse sobre no más del 10 par ciento del costa del programa en paises pequeños (de menos de 30 milliones) y sabre no más del 5 per ciento en paises más grandes.Para medir en que forma el programa satisface el criterio final-la magnitud en que cambia la fecundidad-se debe realizar un trabajo más elaborado en el centro (Universidades, Consejos de población, etc.) para desarrollar una forma (a formas) segura de traducir las estadísticas de servicio en práticas y tal vez aún datos sobre suministro comercial en datos sabre tasas de natalidad. Esto incluye, par ejemplo, los esfuerzos para consolidar observaciones coma "cinco años-mujer de usa de IUD, a 400 condones equivalen a la prevención de un nacimiento," y esfuerzos como los de Pakistán de calcular tasas coma "años de protección de una pareja contra el embarazo."In the belief that a decrease in the rate of population growth will increase economic development, more than ten countries have inaugurated family planning programs in the past fifteen years. To provide a model for measuring the immediate, intermediate, and long-term effects of any such program, the authors use the Taiwan evaluation.The model suggests that a good system of evaluation should include monthly statistics on (1) participants, who are grouped by characteristics; (2) the distribution of supplies, reported at first by the characteristics of recipients, but after by gross volume only; (3) family planning activities of private physicians to measure the catalytic effect on the private sector; (4) new contacts and amount of advertising in mass media; (5) costs broken down by areas and by cost categories; and (6) distribution of commercial supplies. In addition, the program should conduct 300-400 interviews every 6-12 months to learn the rates of continuation and the rates and reasons for discontinuation. Finally, a KAP survey should be conducted every two years.The administration of the evaluation should be close to the director for policy decisions and for the ultimate work of evaluation-the finding of new ways to measure the main goal of change in fertility by the translation of statistics on Services provided and commercial supplies into birth rate data.

    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.

    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.

    RESUMEN Objetivo Mostrar, a través de un diagnóstico en América Latina y el Caribe, el panorama legislativo y curricular sobre sexualidad y prevención contra el virus de inmunodeficiencia humana (VIH) en el ámbito escolar, contrastándolo con los comportamientos sexuales reportados en encuestas demográficas y de salud. Métodos En mayo de 2008 se realizó, con el apoyo del Fondo de Población de las Naciones Unidas (UNFPA), una encuesta a informantes clave en 34 países de la Región. El cuestionario autoaplicado solicitó información sustantiva de agentes de las diferentes partes interesadas, como ministerios de educación y de salud, sobre los programas de prevención contra el VIH/Sida que se están aplicando en las escuelas. Resultados Respondieron a la encuesta 27 países que representan 95,5% de la población objetivo (6 a 18 años de edad). La mayoría de los países informó tener al menos un libro de texto o un capítulo específico para enseñar los temas de educación sobre sexualidad y prevención del VIH. En la escuela secundaria se cubren la mayor parte de los temas pertinentes relevantes para la educación sobre sexualidad, pero no todos. Por ejemplo, el problema de la discriminación por orientación o preferencia sexual no se incluye en los programas escolares. Conclusiones El material educativo sobre sexualidad debe ser revisado y actualizado periódicamente de modo que refleje los avances en los temas y en la forma de tratar los contenidos. En cada país el currículo debe abordar el tema del respeto a la diversidad sobre orientación, preferencia e identidad sexuales, y en particular el manejo apropiado de la educación para prevenir infecciones de transmisión sexual (ITS) en hombres que tienen sexo con hombres. Los esfuerzos de evaluación de la efectividad de los programas deben contemplar desenlaces tales como marcadores biológicos (incidencia y prevalencia de ITS y embarazo) y no únicamente indicadores de conocimiento y comportamiento sexual auto-reportado.

    Arroyo Betancourt, Luz I.

    Esta investigacion estudia la implantacion del enfoque constructivista en tres aulas de ciencia del contexto puertorriqueno. Se auscultaron las practicas educativas que utilizan maestras consideradas constructivistas y la correspondencia de sus practicas educativas con los elementos esenciales de la didactica que proponen los teoricos de los planteamientos constructivistas. Se ausculto, ademas, a que vision del enfoque constructivista responden las expresiones de las maestras acerca de su practica educativa y como compara con su quehacer, a la luz de los elementos esenciales de las visiones constructivistas piagetiana, social y radical. Se utilizo el diseno de estudio descriptivo de caso multiple. El estudio se baso en entrevistas a profundidad, revision de documentos y observacion no participativa a la sala de clases. El contexto fueron tres escuelas publicas de la Region Educativa de San Juan, una elemental, una intermedia y una superior. Los resultados confirmaron que la transicion hacia el enfoque constructivista es un proceso que toma tiempo, dedicacion y la participacion en adiestramientos y readiestramientos acerca del nuevo enfoque. Las maestras coinciden en la mayoria de las practicas educativas que utilizan para implantar el enfoque constructivista de ensenanza y difieren en algunas debido, probablemente, a que han tenido que adaptarlas a los correspondientes niveles de ensenanza: elemental, intermedio y superior. Dos de las maestras planifican por conceptos generadores, mientras que una de ellas planifica siguiendo la guia que recibe del Departamento de Educacion. Difieren ademas, en el enfasis que confieren al inquirir cientifico. Con relacion a la correspondencia entre la vision manifestada por las maestras a la luz de las visiones piagetiana, social y radical, aparentemente, las preguntas del protocolo de entrevistas no lograron evocar la informacion con suficiente profundidad, por lo que la investigadora tuvo que inferir las visiones de las participantes basado en lo que estas manifestaron en su practica didactica. Dos maestras coinciden en una vision constructivista social de la construccion del conocimiento, del aprendizaje y de los metodos didacticos. La otra manifesto una vision constructivista piagetiana en el aprendizaje, los metodos didacticos y en la construccion del conocimiento. Se espera que este trabajo, ademas de promover los estudios de caso sobre el enfoque constructivista de ensenanza en el contexto puertorriqueno, sirva para que los maestros, que estan transformando su enfoque educativo de uno tradicional a uno constructivista, tengan una vision mas clara de la implantacion de este enfoque. Se espera ademas que sirva para que el Departamento de Educacion y sus programas de adiestramiento y readiestramiento en servicio, asi como las universidades y sus programas de preparacion de maestros, tomen en cuenta los resultados y recomendaciones de este estudio al revisar sus programas.

    2008-12-01

    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.

    Las temperaturas efectivas (Teff) y gravedades superficiales (log g) de un grupo de estrellas de tipo B y A de Secuencia Principal se determinaron en varias etapas. En una primera aproximación se usaron los índices fotométricos de Strömgren para realizar el cálculo con el programa de Napiwotski et al.(1993). Luego se hizo un ajuste comparando datos espectrofotométricos con flujos obtenidos con el modelo ATLAS9 en la región visible. Y a continuación se hizo un mejor ajuste comparando los perfiles de la línea Hγ con espectros sintéticos calculados con SYNTHE. Además, se analizó el efecto de usar el modelo de Canuto y Mazzitelli (1991), donde se considera The Mixing Length Theory, en modelos de atmósferas de estrellas.

    SICTI is a software tool for registering health records in critical medicine environments. Version 1.0 has been in use since 2003. The Biomedical Engineering Group (Núcleo de Ingeniería Biomédica), with support from the Technological Development Programme (Programa de Desarrollo Tecnológico), decided to develop a new version, to provide an aid for more critical medicine processes, based on a framework which would make the application domain change oriented. The team analyzed three alternatives: to develop an original product based on new research, to base the development on OpenEHR framework, or to use HL7 RIM as the reference model for SICTI. The team opted for OpenEHR. This work describes the use of OpenEHR, its strong and weak points, and states future work perspectives.

    Las herramientas modernas para detectar duplicidad han jugado un papel fundamental en el resurgimiento del estudio de la binaridad en cúmulos abiertos. El fracaso de las teorías de bifurcación para explicar la formación de estrellas dobles ha puesto en consideración los encuentros de estrellas en cúmulos para formar binarias. Existen muchas pruebas empíricas que pueden realizarse para verificar las creencias actuales. En esta revisión del tema se hace un breve resumen de la historia del problema y se analiza el conocimiento actual. Se proponen las investigaciones y programas que darían lugar a la comprobación de las predicciones que surgen de considerar que las binarias en cúmulos se forman por encuentros.

    An updated list of phlebotomine sand flies species in coffee growing areas in the Colombian Andean region is presented. Fifty three species were reported from 12 departments. In addition, species distribution in the region was derived from specimens obtained during intensive field work in five departments, from previously published studies and from the taxonomic revision of specimens in the entomological collection of the Programa de Estudio y Control de Enfermedades Tropicales (PECET). The list includes the genera Brumptomyia (2 species), Lutzomyia (50 species) and Warileya (1 species). The updated list contains eleven new records in the region under study, including Lutzomyia panamensis , a species of medical importance not recorded previously in this zone. Eighteen of the species are considered to be anthropophilic, and many of them have been implicated in the transmission of leishmaniasis. PMID:25504134

    The immunization Schedule is a dynamic public health tool that has incorporated different changes over the years influenced by the epidemiologic situation and the scientific evidence. The Immunization Advisory Committee [Ponencia de Programa y Registro de Vacunaciones], as the Interterritorial Council scientific and technical advisory body, carries out assessments of different programmes and vaccines and proposes changes that after approval will be introduced in the Regions schedule. This article is divided into two parts presenting the rationale followed to propose a new schedule for the immunization against diphtheria, tetanus, pertussis, hepatitis B and invasive disease by Haemophilus influenzae type b. This first part is focused in the reasoning to undertake the assessment, the review of the immunization policy and the impact of immunization in Spain, as well as a review of the immunization schedules in similar countries.

    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.

    "Escolhas" ("Choices") is a Portuguese programme that aims to promote children and youth social inclusion in deprived socioeconomic contexts. The present study aims to identify internal and external resources perceived by children and adolescents that participated in the programme, to understand the impact in life contexts, and to identify the resources nominated by their family, project professionals and partners. A qualitative method was used in order to analyze 365 discourses from four different groups: children and adolescents (149), family (40), project professionals (126) and project partners (50). The model used was Benard's Conceptual Model for Resilience and Youth Development. The conclusions highlight the success and relevance of Programa Escolhas ("CHOICES") regarding the children and the adolescents and their families, by promoting social inclusion in deprived socioeconomic contexts.

    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.

    This study investigates the effective research-based characteristics of professional development (ERBCPD) of the National Science Foundation's GK-12 Programa program which partners institutions of higher education with local school districts and places science, technology, engineering, and mathematics graduates in the K-12 classroom with teachers. Final evaluations of 26 GK-12 sites were analyzed with a priori and emergent content analyses, which included rigorous inter- and intra-reliability testing. The results of the a priori analysis demonstrated that the GK-12 program incorporates all ERBCPD, but to drastically varying degrees (76-5%). The a priori characteristics that appeared most often were "Treats Fellows as professionals," and "Professional development is on-going." The two emergent characteristics included "Improves communication skills" and "Has real world application."

    For nearly 30 years, Programa Compañeros Inc (Compañeros) has worked in Ciudad Juarez, Chihuahua, Mexico, to ensure that vulnerable populations can exercise their rights to receive HIV and substance abuse prevention and treatment services. Compañeros staff has worked to ameliorate the negative results that limit access to care to the most vulnerable individuals: those who are poor, homeless, sex workers, addicted, and others whose life context put them at greater risk for being infected with HIV. With support from the MAC AIDS Foundation, Compañeros has expanded its capacity to deliver services to persons living with HIV/AIDS (PLWHA) and to HIV-vulnerable populations. This short communication describes findings from an internal evaluation conducted to investigate the effectiveness of the MAC AIDS-funded navigator-based program implemented at Compañeros.

    A comunidade astronômica brasileira de há muito almeja ter a sua disposição um instrumento científico com o qual possa fazer pesquisa de vanguarda e manter a competitividade científica a nível internacional. 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.

  5. Sterile insect technique: A model for dose optimisation for improved sterile insect quality

    2007-03-15

    The sterile insect technique (SIT) is an environment-friendly pest control technique with application in the area-wide integrated control of key pests, including the suppression or elimination of introduced populations and the exclusion of new introductions. Reproductive sterility is normally induced by ionizing radiation, a convenient and consistent method that maintains a reasonable degree of competitiveness in the released insects. The cost and effectiveness of a control program integrating the SIT depend on the balance between sterility and competitiveness, but it appears that current operational programs with an SIT component are not achieving an appropriate balance. In this paper we discuss optimization of the sterilization process and present a simple model and procedure for determining the optimum dose. (author) [Spanish] La tecnica de insecto esteril (TIE) es una tecnologia de control de plagas favorable para el medio ambiente con una aplicacion de un control integrado de plagas claves para toda la area, incluyendo la supresion o eliminacion de poblaciones introducidas y la exclusion de nuevas introducciones. La esterilidad reproductiva es normalmente inducida por radiacion ionizada, un metodo conveniente y consistente que mantiene un grado razonable para la capacidad de competencia en insectos liberados. El costo y la eficacia de un programa de control que incluye TIE dependen en tener un balance entre la esterilidad y la capacidad para competir, pero parece que los programas operacionales corrientes con TIS como un componente no estan logrando el tener un balance apropiado. En esta publicacion, nosotros discutimos la optimizacion del proceso de esterilizacion y presentamos un modelo y procedimiento sencillos para determinar la dosis optima. (author)

    Wavelets e outras formas de análise multiescalar têm sido amplamente empregadas em diversas áreas do conhecimento, sendo reconhecidamente superiores a técnicas mais tradicionais, como as análises de Fourier e de Gabor, em certas aplicações. Embora a teoria dos wavelets tenha começado a ser elaborada há quase trinta anos, seu impacto no estudo de imagens astronômicas tem sido pequeno até bem recentemente. Apresentamos um conjunto de programas desenvolvidos ao longo dos últimos três anos no Observatório do Valongo/UFRJ que possibilitam aplicar essa poderosa ferramenta a problemas comuns em astronomia, como a remoção de ruído, a detecção hierárquica de fontes e a modelagem de objetos com perfis de brilho arbitrários em condições não ideais. Este pacote, desenvolvido para execução em plataforma IDL, teve sua primeira versão concluída recentemente e está sendo disponibilizado à comunidade científica de forma aberta. Mostramos também resultados de testes controlados ao quais submetemos os programas, com a sua aplicação a imagens artificiais, com resultados satisfatórios. Algumas aplicações astrofísicas foram estudadas com o uso do pacote, em caráter experimental, incluindo a análise da componente de luz difusa em grupos compactos de galáxias de Hickson e o estudo de subestruturas de nebulosas planetárias no espaço multiescalar.

    There are few Spanish language interactive, technology-driven health education programs. Objectives of this feasibility study were to: 1) learn more about computer and technology usage among Hispanic women living in a rural community; and 2) evaluate acceptability of the concept of using an embodied conversational agent (ECA) computer application among this population. A survey about computer usage history and interest in computers was administered to a convenience sample of 26 women. A sample video prototype of a hospital discharge ECA was administered followed by questions to gauge opinion about the ECA. Data indicate women exhibited both a high level of computer experience and enthusiasm for the ECA. Feedback from community is essential to ensure equity in state of the art dissemination of health information. Hay algunos programas interactivos en español que usan la tecnología para educar sobre la salud.

    Objetivos. Examiné los efectos combinados del acceso a la atención primaria mediante el Programa de Salud Familiar (PSF) y las transferencias condicionadas de dinero en efectivo del Programa Bolsa Familia (PBF) sobre la mortalidad infantil posneonatal (MIPN) en Brasil. Métodos. Empleé un análisis ecológico longitudinal usando datos en panel de 4 583 municipios brasileños de 1998 al 2010, con 54 253 observaciones en total. Estimé modelos de regresión de efectos fijos por mínimos cuadrados ordinarios, con la tasa de MIPN como la variable dependiente y el PSF, el PBF y sus interacciones como las principales variables independientes de interés. Resultados. La asociación de una mayor cobertura del PSF con una menor tasa de MIPN se volvió más fuerte conforme aumentaba la cobertura del PBF. En los promedios de todas las demás variables, cuando la cobertura de PBF era 25%, la MIPN predicha fue 5,24 (intervalo de confianza [IC] de 95% = 4,95, 5,53) para una cobertura del PSF de 0%, y de 3,54 (IC de 95% = 2,77, 4,31) para una cobertura del PSF de 100%. Cuando la cobertura del PBF era de 60%, la MIPN predicha fue 4,65 (IC de 95% = 4,36, 4,94) para una cobertura del PSF de 0%, y de 1,38 (IC de 95% = 0,88, 1,89) para una cobertura del PSF de 100%. Conclusiones. El efecto del PSF depende de la ampliación del PBF. Para las poblaciones empobrecidas y subatendidas, la combinación de intervenciones tanto del lado de la oferta como del lado de la demanda podría ser necesaria para mejorar los resultados en salud.

  9. Groundwater-flow modeling in the Yucatan karstic aquifer, Mexico

    NASA Astrophysics Data System (ADS)

    2002-09-01

    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 es una manifestación de una zona de alta transmisividad que conduce las aguas subterráneas hacia el Golfo de México y (3) las propiedades geológicas de la porción sur de Yucatán influyen en el sistema de flujo de agua subterránea. El modelo demostró que la falla de la Sierrita de Ticul, situada en el sudoeste de la zona de estudio, actúa como una barrera al flujo, y que los niveles piezométricos disminuyen hacia el nordeste. La modelación también mostró que la dinámica del sistema de flujo regional no ha sido alterada a pesar de la gran cantidad de captaciones, ya que el volumen extraído es pequeño en comparación con la recarga al acuífero además, el sistema cárstico de la región, bien desarrollado, posee una conductividad hidráulica muy elevada.

  10. Liquefaction during the 1977 San Juan Province, Argentina earthquake (Ms = 7.4)

    1994-01-01

    Liquefaction effects generated by the 1977 San Juan Province, Argentina, earthquake (Ms = 7.4) are described. The larger and more abundant effects were concentrated in the 60-km long band of the lowlands in the Valle del Bermejo and in an equally long band along the Rio San Juan in the Valle de Tulum. Fissures in the Valle del Bermejo were up to several hundred meters long and up to several meters wide. Sand deposits, from boils that erupted through the fissures, covered areas up to tens of square meters. Fissures generally parallelled nearby stream channels. Because the Valle del Bermejo is undeveloped, these large features caused no damage. Liquefaction in the Valle del Tulum caused important or unusual damage at several localities, including the following five sites: (1) At the Barrio Justo P. Castro, a subdivision of Caucete, liquefaction of subsurface sediments decoupled overlying, unliquefied stiff sediments, producing a form of ground failure called "ground oscillation". The associated differential ground movements pulled apart houses and pavements in extension, while shearing curbs and buckling canal linings in compression at the same locality. (2) At the Escuela Normal, in Caucete, the roof of a 30-m long single-story classroom building shifted westward relative to the foundation. That displacement fractured and tilted columns supporting the roof. The foundation was fractured at several places, leaving open cracks, as wide as 15 mm. The cumulative width of the open cracks was 48 mm, an amount roughly equivalent to the 63 mm of offset between the roof and foundation at the east end of the building. The ground and foundation beneath the building extended (or spread) laterally opening cracks and lengthening the foundation while the roof remained in place. (3) The most spectacular damage to structures at the community of San Martin was the tilting of a 6-m high water tower and the toppling of a nearby pump house into a 1-m deep crater. Similarly, a small crater developed beneath a hand-pump in an open area and a large, 6-m diameter crater formed nearby. The following sequence of events created the craters and toppled the pump structures: During the earthquake, ground shaking generated excess pore pressures which were dissipated by upward flow of groundwater. Free drainage was restricted by an impermeable plastic-silt layer. Water apparently accumulated below the plastic-silt layer and then burst to the surface through several holes and cracks, including holes around well casings. (4) At the San Isidro winery, nine storage tanks tilted 2 to 5??. Five reinforced-concrete tanks were dismantled but four steel tanks were repaired by placing new footings and jacking the structures into an upright position. (5) At Escuela J.J. Pasos, differential settlement beneath building fractured several columns and walls. The largest settlements were about 60 mm and the maximum settlement of footings supporting columns was about 40 mm. In spite of the damage, the buildings were in no danger of collapse. ?? 1994.

    Introducción: el salmorejo cordobés está tomando fama a nivel nacional y reconocimiento internacional. Sin embargo, son muy diversas las formas de elaborarlo y, por tanto, las propiedades organolépticas y nutricionales del plato.Material y métodos: con la intención de realizar una estandarización del salmorejo y forma de elaboración que permita una posterior protección de su identidad, así como su caracterización nutricional, se ha realizado una encuesta sobre el 83% de los establecimientos de restauración de Córdoba (excluidos barrios periféricos y zona industrial) para indagar su forma de elaborarlo, en cuanto a denominación, ingredientes, preparación, precio, etc., mediante una encuesta administrada personalmente con 55 preguntas en 6 apartados.Resultado: el resultado ha sido que sólo un 21% de los establecimientos utiliza la denominación "salmorejo cordobés". Los ingredientes usados de forma sistemática se ajustan estadísticamente a una propuesta previa de sistematización y valoración nutricional, basada en datos bibliográficos y difundida en más de 50 idiomas, que corresponde a: 1.000 g de tomate, 200 g de pan de telera, 100 g de aceite de oliva virgen extra, 5 g de ajo de Montalbán y 10 g de sal. Esto corresponde por 100 g de producto a 117,4 kcal, 1,8 g de proteínas, 8,1 g de lípidos, 9,9 g de carbohidratos, 1,2 g de fibra y 380,7 mg de sodio. Como ingredientes extra minoritariamente se usa el vinagre (18% de las encuestas) y como guarnición de forma mayoritaria, taquitos de jamón y huevo duro, en tanto que algo más de un 25% añade un chorro de aceite sobre el producto terminado. Se elabora principalmente mediante vaso batidor o Termomix, siendo la receta usada de forma mayoritaria de origen familiar. Si bien se ha considerado tradicionalmente un plato estival, un 78% de establecimientos lo tienen todo el año. El 94% de los establecimientos lo consideran entre los diez platos más consumidos, y para el 18% es el más consumido del establecimiento. No existe relación entre la cantidadde salmorejo servido con el precio del plato, siendo este último acorde a los demás precios de cada establecimiento.Conclusiones: con estos datos y los previos obtenidos por medios bibliográficos se está en condiciones de estandarizar el salmorejo cordobés, tanto para un posible amparo de denominación protegida como para establecer un valor nutricional que pueda ser recogido en bases de datos composicionales y software nutricional, para la evaluación de encuestas o elaboración de dietas.

    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.

  13. Walking through volcanic mud: the 2,100 year-old Acahualinca footprints (Nicaragua) II: the Acahualinca people, environmental conditions and motivation

    We analyzed bare human footprints in Holocene tuff preserved in two pits in the Acahualinca barrio in the northern outskirts of Managua (Nicaragua). Lithology, volcanology, and age of the deposits are discussed in a companion paper (Schmincke et al. Bull Volcanol doi: 10.1007/s00445-008-0235-9 , 2008). The footprint layer occurs within a series of rapidly accumulated basaltic-andesitic tephra that is regionally correlated to the Masaya Triple Layer Tephra. The people were probably trying to escape from a powerful volcanic eruption at Masaya Caldera 20 km farther south that occurred at 2.1 ka BP. We subdivided the swath of footprints, up to 5.6 m wide, in the northern pit (Pit I) into (1) a central group of footprints made by about six individuals, the total number being difficult to determine because people walked in each other’s footsteps one behind the other and (2) two marginal groups on either side of the central group with more widely spaced tracks. The western band comprises tracks of three adjacent individuals and an isolated single footprint farther out. The eastern marginal area comprises an inner band of deep footprints made by three individuals and, farther out, three clearly separated individuals. We estimate the total number of people as 15-16. In the southern narrow and smaller pit (Pit II), we recognize tracks of ca. 12 individuals, no doubt made by the same group. The group represented in both pits probably comprised male and female adults, teenagers and children based on differences in length of footprints and of strides and depth of footprints made in the soft wet ash. The smallest footprints (probably made by children) occur in the central group, where protection was most effective. The footprint layer is composed of a lower 5-15-cm thick, coarse-grained vesicle tuff capped by a medium to fine-grained tuff up to 3 cm thick. The surface on which the people walked was muddy, and the soft ash was squeezed up on the sides of the foot imprints and between toes. Especially, deep footprints are mainly due to local thickening of the water-rich ash, multiple track use, and differences in weight of individuals. The excellent preservation of the footprints, ubiquitous mudcracks, sharp and well-preserved squeeze-ups along the margins of the tracks and toe imprints, and the absence of raindrop impressions all suggest that the eruption occurred during the dry season. The people walked at a brisk pace, as judged from the tight orientation of the swath and the length of the strides. The directions of a major erosional channel in the overlying deposits that probably debouched into Lake Managua and the band of footprints are strictly parallel, indicating that people walked together in stride along the eastern margin of a channel straight toward the lake shore, possibly a site with huts and/or boats for protection and/or escape.

    Introducción: un gran número de encuestas nutricionales en Perú han identificado la magnitud y la ubicación de los diferentes tipos de desnutrición, siendo la forma crónica la más prevalente. Sin embargo, aunque las tasas pueden considerarse alarmantes (aún más en las zonas rurales), sólo un trabajo contiene información sobre las características de la ingesta, usando recordatorios de 24 horas (R24). Es decir, se carece de otros sistemas de estudio centrados en conocer las características gastronómicas de sus regiones y la biodisponibilidad de los alimentos, con el fin de localizar el origen de esta situación en cada área y proponer soluciones verdaderamente eficaces y eficientes.Objetivo: determinar el valor nutricional de los platos principales consumidos por los residentes de un barrio pobre de la Amazonía Peruana, para identificar las causas de la pérdida de un estado nutricional saludable.Métodos: noventa y ocho participantes completaron tres R24. Basándonos en estos datos, se seleccionaron los 25 platos más comúnmente consumidos y evaluamos su composición nutricional. Tomamos nota de las recetas, pesos y medidas caseras. Además, se observó la preparación y cocción. La composición nutricional media de cada plato se calculó por 100 g utilizando el software Nutriplato 4.6. También se calcularon lasganancias o pérdidas derivadas de los tratamientos culinarios.Resultados: dentro de los platos basados en la leche, el de más alta densidad de energía es el mingado de arroz. En el grupo de los pescados, la mayor cantidad de energía es aportada por el pescado frito, mientras que en las recetas a base de carne, las más energéticas son el tallarín con pollo, la res asada y el cerdo frito. Como platos preparados, el juane tiene la más alta densidad de energía de todas las recetas. Dentro de las guarniciones, aquellas que utilizan los plátanos como el ingrediente principal, el plátano frito y el madurito, son las más energéticas. Las grasas son más elevadas en los platos fritos y son estos platos los que más contribuyen al porcentaje total de grasa consumida. Lo mismo ocurre en las guarniciones, donde 100 g de plátano frito o madurito contienen más del 70% de la dosis diaria recomendada. La res asada y el juane tienen el nivel más alto de sodio.Conclusiones: si se desea ofrecer platos más saludables, es necesario cambiar algunos hábitos alimenticios, lo que supone reducir el consumo de alimentos fritos porque probablemente está relacionado con la obesidad y otras enfermedades crónicas cardiovasculares. También se debe reducir la ingesta de sodio. Dos alimentos que podrían ser importantes son la menudencia de pollo, rica en vitaminas del grupo B y baja en grasas, y el frijol hervido, rico en proteínas vegetales, que con platos de arroz, omnipresentes en esta área, incrementaría el valor biológico de las proteínas ingeridas.

    The potential impacts of payments for environmental services (PES) and protected areas (PAs) on environmental outcomes and local livelihoods in developing countries are contentious and have been widely debated. The available evidence is sparse, with few rigorous evaluations of the environmental and social impacts of PAs and particularly of PES. We measured the impacts on forests and human well-being of three different PES programs instituted within two PAs in northern Cambodia, using a panel of intervention villages and matched controls. Both PES and PAs delivered additional environmental outcomes relative to the counterfactual: reducing deforestation rates significantly relative to controls. PAs increased security of access to land and forest resources for local households, benefiting forest resource users but restricting households’ ability to expand and diversify their agriculture. The impacts of PES on household well-being were related to the magnitude of the payments provided. The two higher paying market-linked PES programs had significant positive impacts, whereas a lower paying program that targeted biodiversity protection had no detectable effect on livelihoods, despite its positive environmental outcomes. Households that signed up for the higher paying PES programs, however, typically needed more capital assets; hence, they were less poor and more food secure than other villagers. Therefore, whereas the impacts of PAs on household well-being were limited overall and varied between livelihood strategies, the PES programs had significant positive impacts on livelihoods for those that could afford to participate. Our results are consistent with theories that PES, when designed appropriately, can be a powerful new tool for delivering conservation goals whilst benefiting local people. El Impacto de los Pagos por Servicios Ambientales y Áreas Protegidas sobre la Subsistencia Local y la Conservación del Bosque en el Norte de Camboya Resumen Los impactos potenciales de los pagos por servicios ambientales (PSA) y áreas protegidas (APs) sobre los resultados ambientales y las subsistencias locales en los países en desarrollo son polémicos y se han debatido ampliamente. La evidencia disponible es escasa; ha habido pocas evaluaciones rigurosas de los impactos ambientales y sociales de las APs y particularmente los PSA. Medimos el impacto sobre los bosques y el bienestar humano en tres diferentes programas de PSA que se llevan a cabo dentro de dos APs en el norte de Camboya usando un panel de aldeas de intervención y controles emparejados. Tanto los PSA como las APs brindaron resultados ambientales adicionales en relación a los contrafácticos, esto quiere decir que redujeron las tasas de deforestación significativamente en relación a los controles. Las áreas protegidas incrementaron el acceso seguro a los recursos del suelo y el bosque para las viviendas locales, beneficiando a los usuarios de los recursos del bosque pero restringiendo la habilidad de las viviendas para expandirse y diversificar su agricultura. Los impactos de los pagos por servicios ambientales sobre el bienestar de las viviendas estuvieron relacionados con la magnitud de los pagos proporcionados. Los dos programas de PSA de mayor paga y con conexión al mercado tuvieron impactos positivos significativos, mientras que un programa de menor paga con el objetivo de proteger a la biodiversidad no tuvo un efecto detectable sobre las viviendas, a pesar de sus resultados ambientales positivos. Las viviendas que se inscribieron a los programas de PSA con mayor paga, sin embargo, necesitaban típicamente más bienes capitales, por lo que eran menos pobres y tenían mayor seguridad alimentaria que otros aldeanos. Por esto, mientras los impactos de las APs sobre el bienestar de las viviendas fueron limitados en general y variaron dependiendo de las estrategias de subsistencia, los programas de PSA tuvieron impactos positivos significativos sobre las viviendas para aquellos que podían costear participar. Nuestros resultados son congruentes con las teorías de que los PSA, cuando se designan apropiadamente, pueden ser una herramienta poderosa y novedosa para obtener objetivos de conservación mientras se beneficia a la gente local.

    Sterile male insects, mass-reared and released as part of sterile insect technique (SIT) programs, must survive long enough in the field to mature sexually and compete effectively with wild males for wild females. An often reported problem in Mediterranean fruit fly (medfly) Ceratitis capitata (Wiedemann) SIT programs is that numbers of released sterile males decrease rapidly in the field for various reasons, including losses to different types of predators. This is a serious issue in view that most operational programs release sterile flies at an age when they are still immature. Previous field and field-cage tests have confirmed that flies of laboratory strains are less able to evade predators than wild flies. Such tests involve, however, considerable manipulation and observation of predators and are therefore not suitable for routine measurements of predator evasion. Here we describe a simple quality control method with aspirators to measure agility in medflies and show that this parameter is related to the capacity of flies to evade predators. Although further standardization of the test is necessary to allow more accurate inter-strain comparisons, results confirm the relevance of measuring predator evasion in mass-reared medfly strains. Besides being a measure of this sterile male quality parameter, the described method could be used for the systematic selection of strains with a higher capacity for predator evasion. (author) [Spanish] Insectos machos esteriles criados en forma masiva para ser liberados en programas que utilizan la tecnica del insecto esteril (TIE), tienen que tener la capacidad de sobrevivir en el campo el tiempo necesario para poder madurar sexualmente y competir efectivamente con los machos silvestres por hembras silvestres. Un problema frecuentemente reportado por dichos programas de la mosca del Mediterraneo, Ceratitis capitata (Wiedemann), es que el numero de machos esteriles de laboratorio liberados en el campo, decrecen rapidamente por varias razones, incluyendo perdidas debidas a diferentes tipos de depredadores. Estudios anteriores conducidos en el campo, y en jaulas de campo, han confirmado que las cepas de machos de laboratorio tienen menos capacidad de evadir depredadores que los machos silvestres. Estos estudios involucran, sin embargo, una considerable cantidad de manipulacion y observacion de depredadores, por lo que no son adecuados para ser usados como medidas rutinarias en los programas de cria masiva. Aqui describimos un metodo sencillo de control de calidad usando aspiradores para medir agilidad en la mosca del Mediterraneo y mostramos que este parametro esta relacionado a la capacidad de la moscas a evadir a depredadores. Aunque aun es necesario refinar la estandarizacion de este metodo para permitir la comparacion entre cepas, los resultados confirman la importancia de tener un metodo rutinario para medir la capacidad de evasion de depredadores en cepas de cria de laboratorio de la mosca del Mediterraneo. Ademas de medir este parametro de control de calidad de los machos esteriles, el metodo descrito podria tambien ser usado para la seleccion sistematica de cepas con una mayor capacidad de evasion de depredadores.

    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.

  20. Modelagem do vento e da fotosfera de AG Carinae

    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.

    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.

    Objetivos. Analizamos si la participación de las escuelas en el Programa de Mejoramiento del Recreo (PMR) en la primavera del año 2011 estuvo asociada a tasas más altas de actividad física intensa en los niños. Métodos. En el PMR, un coordinador dirige a los niños para que practiquen juegos adecuados para la edad a fin de aumentar su nivel de actividad física. Durante el recreo en 25 escuelas primarias públicas de la ciudad de Nueva York (15 participantes en el PMR, 10 no participantes en el PMR) los investigadores observaron algunas áreas predeterminadas (n = 1 339 observaciones) y registraron el número de niños que estaban sedentarios, caminando o muy activos. Resultados. Tras el análisis estadístico con múltiples variables se encontró que la participación en el PMR era una variable predictiva significativa (P = 0,027) de la tasa de actividad física intensa (porcentaje de niños muy activos en las áreas de observación) cuyas medias de los mínimos cuadrados fueron de 41% en las escuelas participantes en el PMR y de 27% en escuelas no participantes en el PMR. En las escuelas participantes en el PMR se siguió registrando una tasa significativamente superior incluso cuando el coordinador de juegos no estaba en el área de observación, lo que sugiere un cambio en la cultura del recreo en las escuelas que participan en este programa. Conclusiones. La tasa de actividad física intensa en las escuelas participantes en el PMR fue 14 puntos porcentuales (o 52%) superior a la tasa registrada en las escuelas no participantes en el PMR. Esta intervención de bajo costo podría ser un agregado valioso a las herramientas para combatir la obesidad infantil y podría valer la pena reproducirla en otros sitios. PMID:24899455

    The importance of the textbooks in classrooms is revealed when studies are pointing that these pedagogical sources are, most of the times, the only source used by the elementary school teachers when preparing their Science lessons. When we analyzed the Astronomy contents in the textbooks approved by the Brazilian Textbook Program 2008 and which, in theory, are the best available in the Brazilian editorial market, we examined some categories in the 2008 Textbook Guide. This research characterizes the frequency of Astronomical contents appearing in the texts, in the pictures, and in the hands-on activities. Additionally, it describes some misconceptions and presents additional information on the collections. La importancia de los libros de texto en las aulas se pone de manifiesto cuando los estudios indican que este recurso educativo es a menudo la única fuente de consulta utilizada por el profesor de ciencias de la escuela primaria para preparar sus lecciones. Cuando analizamos el contenido presente en los libros de texto de astronomía aprobados por el Programa Nacional de Libros de Texto de 2008 y que, en teoría, son los mejores libros disponibles en el mercado editorial brasileño, buscamos examinar algunas categorías que figuran en los libros de texto de la Guía de Libros Didácticos de 2008. El estudio caracteriza la frecuencia del contenido de Astronomía en el texto, en las figuras, y en las actividades de experimentación. También describe algunos errores conceptuales y presenta un conjunto de información adicional sobre las colecciones. A importância dos livros didáticos nas salas de aula revela-se quando estudos apontam que este recurso pedagógico é, muitas vezes, a única fonte de consulta utilizada pelo professor de Ciências do ensino fundamental para a preparação de suas aulas. Quando analisamos os conteúdos de Astronomia presentes nos livros didáticos aprovados no Programa Nacional do Livro Didático de 2008 e que, teoricamente, são os melhores livros disponíveis no mercado editorial brasileiro, buscamos esquadrinhar algumas categorias constantes no Guia de Livros Didáticos de 2008. A pesquisa caracteriza a freqüência do conteúdo de Astronomia no texto, nas figuras e nas atividades de experimentação. Além disso, descreve alguns erros conceituais e apresenta um conjunto de informações adicionais sobre as coleções.

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

    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.

    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.

    Apesar da astronomia ser um dos temas indicados pelos Parâmetros Curriculares Nacionais, observa-se que poucas mudanças ocorreram desde a implementação do mesmo em sala de aula. A presente pesquisa diz respeito sobre como os tópicos de astronomia estão sendo abordados pelos professores no ensino médio. Optou-se por aplicar um questionário com os professores que ministram a disciplina de física. Os mesmos trabalham em escolas estaduais situadas nas cidades de Ribeirão Pires e Rio Grande da Serra, ambas subordinadas a Diretoria de Ensino de Mauá, no Estado de São Paulo. O questionário foi aplicado durante o 2° semestre de 2006. Até o momento os resultados são preliminares. Dos 82,0% dos professores que responderam ao questionário no município de Rio Grande da Serra, 66,7% não aplicaram nenhum tópico de astronomia, 77,8% não utilizaram qualquer tipo de programa computacional, 66,7% não utilizaram laboratório, que 77,8% nunca levaram os alunos a museus e ou planetários e que 66,7% não indicaram qualquer tipo de revista ou livro sobre astronomia aos seus alunos. No município de Ribeirão Pires, 53,3% dos professores responderam ao questionário, destes 75,0% não aplicaram nenhum tópico de astronomia, 93,8% não utilizaram qualquer tipo de programa computacional, 75,0% não utilizaram laboratório, 81,3% nunca levaram os alunos a museus e ou planetário e 56,3% não indicaram qualquer tipo de revista ou livro sobre astronomia ao seus alunos. Apesar da maioria dos professores reconhecerem que o conteúdo de astronomia influi na formação do jovem, os mesmos não incluem o tema em seus planejamentos escolares.

    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.

  8. Comportamiento del Helio en estrellas químicamente peculiares

    Malaroda, S. M.; López García, Z.; Leone, F.; Catalano, F.

    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.

    In 1996, in Western Sydney, Australia, the Area Health Service and the University of Western Sydney entered a strategic alliance to develop a nursing research culture in the health services. One of the strategies implemented to achieve this was the establishment of a network of research-receptive environments known as Clinical Development Units (CDUs). At the time, however, evidence suggested that research receptivity will only develop in units where the leadership style is permissive and participatory; evidence also suggested that the successful establishment of CDUs hinged critically on the effective management of CDU leadership stressors. In light of this, it was agreed to conduct a CDU Leadership Preparation Program in Western Sydney. The aim of the program was to equip CDU leaders with the participatory leadership skills required to develop and manage their units. It was anticipated that the acquisition of these leadership skills would, in turn, help them minimise the leadership stressors to which they could expect to become subject. This paper provides details of the first CDU leadership preparation course: how participants were selected, the aims of the course and its content. It focuses, however, on a discussion of the positive evaluative data harvested through 2 focus group interviews which were conducted 5 months following participants' successful completion of the program.A second paper focuses on the more negative evaluative data, 2 themes which unexpectedly emerged during data analysis and how the current program has been modified in light of this data.

    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.

    2012-01-01

    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. PMID:22747646

    Children from disadvantaged backgrounds often face impoverished auditory environments, such as greater exposure to ambient noise and fewer opportunities to participate in complex language interactions during development. These circumstances increase their risk for academic failure and dropout. Given the academic and neural benefits associated with musicianship, music training may be one method for providing auditory enrichment to children from disadvantaged backgrounds. We followed a group of primary-school students from gang reduction zones in Los Angeles, CA, USA for 2 years as they participated in Harmony Project. By providing free community music instruction for disadvantaged children, Harmony Project promotes the healthy development of children as learners, the development of children as ambassadors of peace and understanding, and the development of stronger communities. Children who were more engaged in the music program-as defined by better attendance and classroom participation-developed stronger brain encoding of speech after 2 years than their less-engaged peers in the program. Additionally, children who were more engaged in the program showed increases in reading scores, while those less engaged did not show improvements. The neural gains accompanying music engagement were seen in the very measures of neural speech processing that are weaker in children from disadvantaged backgrounds. Our results suggest that community music programs such as Harmony Project provide a form of auditory enrichment that counteracts some of the biological adversities of growing up in poverty, and can further support community-based interventions aimed at improving child health and wellness.

    Se determinan las abundancias químicas de los elementos más livianos presentes en dos estrellas CP del grupo HgMn, μ 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.

    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.

    Intradyalitic exercise programas are important to improve patient's hemodynamic stability. Blood pressure and metabolic changes are correlated when heat accumulation is due to increment of the body core temperature (+1.0 °C). However, increase in temperature could be controlled by lowering dialysate's temperature using two main modalities techniques (isothermic and thermoneural) with different patient's thermal balance consequences, not yet well studied. In this work, a new method to observe the main physiological parameters (hearth rate variability (HRV), blood pressure, BTM dialysate temperature control and substrate utilization by indirect calorimtery) which are involved in hemodiafitration (HDF), are displayd. An experiment was carried out in a group of 5 patients waiting kidney transplant. In each patient, EE was assessed as well as the HRV during isothermic and thermoneutral modalities as a manner of cross and prospective study (a) at before therapy, (b) during therapy and (c) at the end of the HDF therapy. Power extraction was also measured by a BTM (Blood Temperature Monitor from Fresenius Inc), in order to determine how the dialysate temperature was controlled. The results showed important method's advantages which place the BTM performance as unstable control system with the possibility to produce undesirable HRV changes as the vagotonical response. However more patient cases are needed in order to identify the real advantage of this new method. PMID:21095679

    In 1996, the Brazilian Society for Clinical Densitometry (SBDens) developed an accreditation program to be applied to all densitometry centers, under the supervision of the certified physicians from SBDens. This program is named Programa Nacional de Qualidade em Densitometria (PROQUAD) and was developed to verify at least three aspects of the bone densitometry practice: the functioning of equipment, the methods used by technicians in performing the scans, and how the physicians are analyzing the scans and interpreting the results. From the 360 certified physicians who are members of SBDens, nearly one-third are participating in this program. The final purpose of PROQUAD is to provide approved centers with a seal, to be stamped on their examinations. The seal will signify to referring physicians, and the community, which centers are working under high standards of quality. It has been 2 yr since PROQUAD was established, and the data obtained confirm the improvement of quality in the practice of densitometry in Brazil. Any input from other societies that could improve PROQUAD is welcomed. Ensuring good densitometry practices is a goal for which all densitometry societies must strive. PMID:10677800

    Argentina is a large country situated at the southern end of the Americas. It is highly urbanized, and almost one-third of the population lives in the capital city and its surrounding area (Buenos Aires). The population is composed of heterogeneous groups, formed primarily by descendants of European immigration who constitute 85% of the inhabitants. In the last 30 years, Argentina has witnessed a growth in the elderly population from less than 7% to nearly 10% of the total population. Additionally, in Buenos Aires City, more than 17% are aged 65 or older. The healthcare systems for the elderly lack nationwide coverage. The Programa de Atención Médica Integral (PAMI) is the largest program for elderly care. It is a state-run program for disabled and senior citizens. PAMI serves 65% of the approximately 3.6 million older people in Argentina. The quality of PAMI healthcare delivery has decreased in the last 2 decades and has largely declined since the Argentinean economic crisis of late 2001. The rehabilitation and long-term care services are relatively underdeveloped, and fewer than 2% of senior citizens live in residential or nursing homes. Recently, the government has proposed a system of care built up from the primary care resources of the community. PMID:15450058

    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.

    In 1993 the National Science Foundation and The Whitaker Foundation jointly supported an experimental initiative entitled `Cost Effective Health Care Technologies'. The broad goal of the 1993 program was to `promote innovative multidisciplinary research that can contribute to the containment or reduction of health costs without compromising the quality, effectiveness or accessibility of the health care system'. Proposals were required to contain a section which `describes as quantitatively as possible' the expected impact of the research results on the cost- effectiveness goal of the program--a new parameter for research methodologies. Twelve projects in the categories of Information and Systems, Medical Devices, and Biomaterials were funded. A modified program, `Cost Reducing Health Care Technologies', is planned for Fiscal Year 1995. Insights gained in the planning, conduct, and follow-up review of the 1993 experimental biomedical engineering research grant program provide useful background information on `The Role of Technology in the Cost of Health Care'. The desirability is indicated for engineers to participate in the development of a credible and robust technology assessment process at the basic and applied research stages of health care technology development.

    Maternal and neonatal mortality in Northern Guatemala, a region with a high percentage of indigenous people, is disproportionately high. Initiatives to improve quality of care at local health facilities equipped for births, and increasing the number of births attended at these facilities will help address this problem. PRONTO (Programa de Rescate Obstétrico y Neonatal: Tratamiento Óptimo y Oportuno) is a low-tech, high-fidelity, simulation-based, provider-to-provider training in the management of obstetric and neonatal emergencies. This program has been successfully tested and implemented in Mexico. PRONTO will now be implemented in Guatemala as part of an initiative to decrease maternal and perinatal mortality. Guatemalan health authorities have requested that the training include training on cultural humility and humanized birth. This article describes the process of curricular adaptation to satisfy this request. The PRONTO team adapted the existing program through 4 steps: (a) analysis of the problem and context through a review of qualitative data and stakeholder interviews, (b) literature review and adoption of a theoretical framework regarding cultural humility and adult learning, (c) adaptation of the curriculum and design of new activities and simulations, and (d) implementation of adapted and expanded curriculum and further refinement in response to participant response.

    In Chile, the National Depression Detection and Treatment Program (Programa Nacional de Diagnóstico y Tratamiento de la Depresión, PNDTD) in primary care is a rare example of an evidence-based mental health program that was scaled up to the national level in a low- or middle-income country. This retrospective qualitative study aimed to better understand how policymakers made the decision to scale up mental health services to the national level, and to explore the elements, contexts, and processes that facilitated the decision to implement and sustain PNDTD. In-depth semistructured interviews with six key informants selected through intentional sampling were conducted in August-December 2008. Interviewees were senior officers at the Ministry of Health who were directly involved in the decision to scale up the program. Results yielded four elements pivotal to the decisionmaking process: scientific evidence, teamwork and leadership, strategic alliances, and program institutionalization. Each element contributed to building consensus, securing funding, attracting resources, and gaining lasting support from policymakers. Additionally, a review of available documentation led the authors to consider sociopolitical context and use of the media to be important factors. While research evidence for the effectiveness of mental health services in the primary care setting continues to accumulate, low- and middle-income countries should get started on the lengthy process of scaling up by incorporating the elements that led to decisionmaking and implementation of the PNDTD in Chile.

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

    The Efectividad de un Programa de Intervención en el Control de la Presión Arterial de los Hipertensos en Riesgo de Desarrollar Insuficiencia Cardiaca (HEROIC) study was designed to assess whether an educational program for primary care physicians could improve blood pressure (BP) control in hypertensive patients at high risk for developing heart failure. The program contained a combination of educational training (live group sessions or online training) and information feedback. Two hundred twenty-six physicians completed the program and provided valid data in 2489 patients before and 2168 after 1 year. There was a small but significant reduction of -1.1 mm Hg (P=.009) in systolic BP and a higher proportion of patients achieved their BP target (13.6% vs 15.6%, P=.055). Thus, the authors concluded that there was a slight improvement in BP control after the educational program, but this change was not sufficient to avoid development of heart failure. More complex and intensive programs are needed for this type of prevention. PMID:20546374

    Due to Brazil is a tropical country has activities in occupational exposure to cold restricted to few sectors especially the meatpacking industry. Taking into account that the country in 2010, was again the largest exporter of poultry meat in the world and consequently employing a large number of workers for their slaughter and processing. The search for greater productivity can result in an increase in work rate, as indicated in this sector as monotonous, repetitive and uncomfortable. According the Programa de Frigorífico it was found that within six years, about 20% of the six thousand workers in a slaughterhouse in southern Brazil, received welfare benefits due to musculoskeletal diseases. Adding to this, the lack of parameters for the Brazilian standardization concerning occupational activities carried out in cold. Although several epidemiological studies point to the cold as a risk factor for occurrence or aggravation of musculoskeletal disorders, research in this field is still limited and often contradictory conclusions. This article aims to review developments concerning the poultry industry and the fridge in Brazil, as well as raising the question about the increased productivity of the slaughterhouse, since it has already shown a high prevalence of musculoskeletal disorders related to work.

    Pasa la Voz (spread the word) is a human immunodeficiency virus (HIV) prevention methodology inspired by respondent-driven sampling (RDS) that uses social networks to access hard-to-reach populations. As field testing showed the approach to be efficacious among at-risk women in West Texas and Southern New Mexico, we set out to evaluate the methodology in a Mexican context. A local community organization, Programa Compañeros, first implemented a traditional one-on-one outreach strategy using promotoras (outreach workers) in Ciudad Juarez, Mexico, from September 2005 to January 2006. This was followed by implementation of Pasa la Voz from February 2006 to January 2007. The percentage of women agreeing to be tested increased from 11.9% to 49.9%, and staff time declined from 22.70 hours to 3.68 hours per HIV test, comparing the one-on-one with the Pasa la Voz methodology, respectively. Pasa la Voz was successful at imparting a cost-savings prevention education program with significant increases in the number of at-risk women being tested for HIV. PMID:20597452

    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 Espaol de Tratamientos en Hematologa [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%).

    Differentiation syndrome (DS), formerly known as retinoic acid syndrome, is the main life-threatening complication of therapy with differentiating agents (all-trans retinoic acid [ATRA] or arsenic trioxide [ATO]) in patients with acute promyelocytic leukemia (APL). The differentiation of leukemic blasts and promyelocytes induced by ATRA and/or ATO may lead to cellular migration, endothelial activation, and release of interleukins and vascular factors responsible of tissue damage. Roughly one quarter of patients with APL undergoing induction therapy will develop the DS, characterized by unexplained fever, acute respiratory distress with interstitial pulmonary infiltrates, and/or a vascular capillary leak syndrome leading to acute renal failure. Although the development of the DS, particularly of the severe form, is still associated with a significant increase in morbidity and mortality during induction, the early administration of high-dose dexamethasone at the onset of the first symptoms seems likely to have dramatically reduced the mortality rate of this complication. In this article, we will review the clinical features, incidence, prognostic factors, management, and outcome of the DS reported in the scientific literature. We will make focus in the experience of the three consecutive Programa Espaol de Tratamientos en Hematologa trials (PETHEMA LPA96, LPA99, and LPA2005), in which more than one thousand patients were treated with ATRA plus idarubicin for induction.

    Members of the Education Committee of the Brazilian Society of Physiology have developed multiple outreach models to improve the appreciation of science and physiology at the precollege level. The members of this committee act in concert with important Brazilian governmental strategies to promote training of undergraduate students in the teaching environment of secondary and high schools. One of these governmental strategies, the Programa Institucional de Bolsas de Iniciação à Docência, a Brazilian public policy of teaching enhancement implemented by the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) since 2007, represents a well-articulated public policy that can promote the partnership between University and Schools (7). Furthermore, the Program "Novos Talentos" (New Talents)/CAPES/Ministry of Education is another government initiative to bring together university and high-level technical training with the reality of Brazilian schools. Linked to the New Talents Program, in partnership with the British Council/Newton Fund, CAPES recently promoted the visit of some university professors that coordinate New Talents projects to formal and informal educational science spaces in the United Kingdom (Science, Technology, Engineering, and Mathematics, Brazil-United Kingdom International Cooperation Program) to qualify the actions developed in this area in Brazil, and one of us had the opportunity to participate with this.

    The study evaluated free access to hypertension and diabetes medicines and the reasons reported for lack of access. The sample included 4,003 elderly people living in Primary Care Unit coverage areas from 41 Southern and Northeastern Brazilian cities. Free access was higher in the Northeast (62.4%). The strategy of the Family Health Program (Programa Saúde da Família - PSF) was more effective in providing access than the traditional model, with higher results in the Northeast (61.2%) than in the South (39.6%). Around 20% of medicines included in the Hypertension and Diabetes Program and 26% of those included in the National Essential Medicines List (RENAME) were paid out of pocket. In the Northeast, 25% of insulin and 32% of oral antidiabetics were paid out of pocket. Unavailability in the public sector and a lack of money determined the lack of access. Although the PSF, Hypertension and Diabetes Program and RENAME expanded free access, supplies were insufficient. A greater connection between programs and a clear definition of responsibilities can improve medicine acquisition process, increasing the effectiveness of pharmaceutical assistance. PMID:20657981

    This study discusses the role the Brazilian Home Health Care Program (Programa de Atenção Domiciliar - PAD) plays in supplementary care using the example of a Group Care provider headquartered in Rio de Janeiro. The purpose of the study was to understand how home health care is produced by verifying the interaction between the medical team, beneficiaries and family members considering that the service in this care model is delivered in the micro-political scenery of the process, in the client's own home. The assessment of this program must consider: infrastructure and logistics, beneficiary eligibility criteria, the care-network formed in support of the PAD and above all the work process. Especially the latter is a strong indicator, in the present case characterized by an eminently multi-professional team operating in networks with integrated therapeutic projects. For the professionals, Home Health Care has the meaning of an innovative and highly valuable approach to care delivery. The article concludes considering the PAD an important device for a fruitful restructuring of supplementary care through different ways of care delivery. PMID:18813653

    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.

    In this paper some preliminary fossil specimens are presented. They represent a collection sampled by Belo Monte's Programa de Salvamento do Patrimônio Paleontológico (PSPP), which includes unprecedented invertebrate fauna and fossil vertebrates from Pitinga, Jatapu, Manacapuru, Maecuru e Alter do Chão formations from Amazonas basin, Brazil. The Belo Monte paleontological salvage was able to recover 495 microfossil samples and 1744 macrofossil samples on 30 months of sampling activities, and it is still ongoing. The macrofossils identified are possible plant remains, ichnofossils, graptolites, brachiopods, molluscs, athropods, Agnatha, palynomorphs (miosphores, acritarchs, algae cysts, fungi spores and unidentified types) and unidentified fossils. However, deep scientific research is not part of the scope of the program, and this collection must be further studied by researchers who visit Museu Paraense Emilio Goeldi, where the fossils will be housed. More material will be collected until the end of the program. The collection sampled allows a mosaic composition with the necessary elements to assign, in later papers, taxonomic features which may lead to accurate species identification and palaeoenvironmental interpretations.

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 (Hα /[NII]λ 6583 y [SII]λ 6731/λ 6716) indicarían niveles de excitación y densidad electrónica normales en regiones HII, aún en la zona nuclear.

Intervention study involving participants in the Health Gym Programme which encompasses group food and nutrition education activities over a period of 11 months combined with regular physical activity. Impact was assessed by comparing nutritional and anthropometric indicators in women participants who were divided into two groups according to their participation rate in the intervention. A total of 124 women were evaluated, results showed an increase in the number of daily meals (p<0.001) among all participants. Participants whose participation rate was less than 50% (n = 61) reduced their daily consumption of sugary soft drinks (p = 0.03), while those whose participation rate was 50% and over (n = 63) reduced daily per capita intake of oil (p = 0.01) and sugar (p = 0.002), increased their consumption of fruit (p = 0. 004), and milk and dairy products (p = 0.02), and also experienced weight loss (-1.3 ± 3.9kg; p = 0.02). The findings show the importance of combining nutritional interventions with physical activity to ensure positive impacts on the nutritional status and anthropometric profile of participants in the Health Gym Programme.

  9. Plan for a groundwater monitoring network in Taiwan

    NASA Astrophysics Data System (ADS)

    Hsu, Shiang-Kueen

    In Taiwan, rapid economic growth, rising standards of living, and an altered societal structure have in recent years put severe demands on water supplies. Because of its stable quantity and quality, groundwater has long been a reliable source of water for domestic, agricultural, and industrial users, but the establishment of a management program that integrates groundwater and surface-water use has been hampered by the lack of groundwater data. In 1992, the Department of Water Resources (DWR) initiated a program entitled "Groundwater Monitoring Network Plan in Taiwan." Under this program, basic groundwater data, including water-level and water-quality data, are being collected, and a reliable database is being established for the purpose of managing total water resources. This paper introduces the goals, implementation stages, and scope of that plan. The plan calls for constructing 517 hydrogeologic survey stations and 990 groundwater monitoring wells within 17 years. Under this program, water-level fluctuations are continuously monitored, whereas water-quality samples are taken for analysis only at the initial drilling stage and, subsequently, at the time when a monitoring well is being serviced. In 1996, the DWR and the Water Resources Planning Commission were merged to form today's Water Resources Bureau. Résumé A Taïwan, l'expansion économique rapide, l'amélioration des conditions de vie et la transformation de la structure sociale ont provoqué, ces dernières années, une très forte demande en eau. Du fait de sa constance en qualité et en quantité, l'eau souterraine a longtemps été considérée comme une ressource en eau sûre pour les usages domestiques, agricoles et industriels. Mais la mise en place d'un programme de gestion intégrant les utilisations d'eaux souterraines et de surface a été gênée par l'absence de données sur les eaux souterraines. En 1992, le Département des Ressources en Eau a lancé le programme "Plan pour un réseau de suivi des eaux souterraines à Taïwan". D'après ce programme, les données de base concernant les eaux souterraines, comprenant les mesures de niveau et les données de qualité, ont été acquises ; une base de données sûre est en cours d'élaboration, dans le but de gérer l'ensemble des ressources en eau. Cet article présente les buts, les stades de développement et une vue d'ensemble de ce plan. Le plan impose la mise en place de 517 stations de mesures hydrogéologiques et de 990 piézomètres en 17 ans. Selon ce programme, les variations du niveau des nappes doivent être suivies en continu, tandis que des échantillons pour la qualité de l'eau seront prélevés pour analyses uniquement au cours de la phase de foration, puis au moment de la mise en service des piézomètres. En 1996, le Département des Ressources en Eau et la Commission de Planification des Ressources en Eau ont été réunis pour former l'actuel Bureau des Ressources en Eau. Resumen En Taiwan, el rápido crecimiento económico, el aumento en el nivel de vida y los cambios sociales en los últimos años han resultado en un aumento en la demanda de agua. Por su estabilidad en términos de cantidad y calidad, las aguas subterráneas han sido durante años la fuente de agua para usos domésticos, agrícolas e industriales. En los últimos años, sin embargo, el establecimiento de un programa de gestión conjunta de aguas superficiales y subterráneas se ha visto comprometido por la falta de datos correspondientes a estas últimas. En 1992, el Departamento de Recursos de Agua (DWR) inició un programa titulado "Plan de Red de Control de Aguas Subterráneas en Taiwan". Bajo este programa, se están recogiendo datos básicos, incluyendo niveles piezométricos y datos de calidad, y se está construyendo una base de datos con el propósito de gestionar los recursos de agua totales. Este artículo presenta el marco, los objetivos y el estado de implantación del plan, que pretende la construcción de 517 estaciones de medida hidrogeológicas y 990 pozos de observación durante un periodo de 17 años. Bajo este programa, los niveles de agua se miden continuamente, mientras que las muestras para análisis de calidad se toman sólo durante la perforación y cuando el pozo está en servicio. En 1996, el DWR y la Comisión de Planificación de los Recursos de Agua se unieron para formar la actual Oficina de Recursos de Agua.5

    Under a contract with AIRBUS MILITARY (AI-M), an exercise to analyze the potential of optimization techniques to improve the wing performances at cruise conditions has been carried out by using an in-house design code. The original wing was provided by AI-M and several constraints were posed for the redesign. To maximize the aerodynamic efficiency at cruise, optimizations were performed using the design techniques developed internally at INTA under a research program (Programa de Termofluidodinámica). The code is a gradient-based optimizaa tion code, which uses classical finite differences approach for gradient computations. Several techniques for search direction computation are implemented for unconstrained and constrained problems. Techniques for geometry modifications are based on different approaches which include perturbation functions for the thickness and/or mean line distributions and others by Bézier curves fitting of certain degree. It is very e important to afford a real design which involves several constraints that reduce significantly the feasible design space. And the assessment of the code is needed in order to check the capabilities and the possible drawbacks. Lessons learnt will help in the development of future enhancements. In addition, the validation of the results was done using also the well-known TAU flow solver and a far-field drag method in order to determine accurately the improvement in terms of drag counts.

  15. Precise U-Pb dating of Cenozoic tropical reef carbonates: Linking the evolution of Cenozoic Caribbean reef carbonates to climatic and environmental changes.

    Coral reefs are very diverse and productive ecosystems; and have long been the base of the economic activity of several countries along the tropics. Because coral reefs are very sensitive to environmental changes and their adaptation to changing stressing conditions is very slow, the combination of current rapid environmental changes and the additional stresses created by growing human populations (i.e. rapid anthropogenic CO2 additions to the atmosphere),plus the economic and coastal development may become a lethal synergy. The ongoing acidification of modern oceans is a major issue of concern because it may have serious consequences for the survival of shelly marine invertebrates as the 21st century progresses. Ocean Acidification (OA) is now being driven by rapid CO2 release to the atmosphere. Although evidences of the devastating effects of oceanic acidification in the marine biota are provided by the decreased rate of coral skeleton production and the reduced ability of algae and free-swimming zooplankton to maintain protective shells, among others, predicting the effects of oceanic acidification on the future oceans (2050-2100) has remained rather difficult because the atmospheric CO2 sequestration by the global oceans occurs in geologic time scales. Important changes in the atmospheric pCO2 and major climatic/environmental events seem to have controlled the evolution of the Cenozoic equatorial-tropical carbonates r1-10. Rapid additions of green house gases to the atmosphere occurred during the Paleocene-Eocene transition and would have promoted several other events of global warming until the early Oligocene (i.e. the Eocene thermal maximum). These periods of high greenhouse gases concentrations would have also resulted on OA, affecting the reef carbonate ecology and tropical carbonate budgets. Relating temporal variations in the Cenozoic reef carbonate structure, ecology and factory is vital to help understanding and predicting the future effects of the rapid anthropogenic CO2 release to the atmosphere on reef areas. Here we report precise U-Pb ages of several Cenozoic Caribbean-tropical reef carbonate successions along the SE Circum-Caribbean Region from which major temporal variations in the reef carbonate factories, structure and ecology are related to major climate/environmental changes. Calcareous algae are the principal calcifying reef builders along the SE Circum-Caribbean during the Paleocene-middle Oligocene interval, a period of predominant high atmospheric pCO2 and OA. Calcareous algae persisted as the main calcifying reef builders until the late Oligocene when atmospheric pCO2 levels dropped, allowing the onset of global icehouse conditions and the appearance of corals as the main calcifying reef builders along the SE Circum-Caribbean. Coral reefs would have dominated until the middle Miocene, when a new period of calcareous algae reefs occurred along the Caribbean, coinciding with the Miocene thermal optimum in mid-latitude areas (i.e. the Mediterranean). Coral reef carbonates dominated since the Pliocene. From the data presented here we suggest that calcareous algae dominated were the main calcifying reef builders during periods of warm temperatures and pronounced environmental change in the tropical seas (i.e. OA). Corals would have conversely dominated as main calcifying reef builders during periods of optimal tropical climatic/environmental conditions. Comparisons between this geologic conditions and data for the period 1984-2006 in the Caribbean11 suggest that the transition from corals towards calcareous algae is repeating again. 1.Zachos et al., Science Mag. 292 (2001) 2.Zachos et al., Science Mag. 308 (2005) 3.Haug et al., Geology 29 (2001) 4.Jain and Collins, Marine Micropaleo. 62 (2007) 5.Merinco et al., Nature 452 (2008) 6.O'Dea et al., Proc.

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

    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.

  17. EDITORIAL: Special Issue: CAMOP MOLEC XV

    NASA Astrophysics Data System (ADS)

    2006-01-01

    The advances in recent years in the field of molecular dynamics are numerous and impressive. In sophisticated experimental and theoretical studies it is nowadays possible to steer chemical reactions with quantum-number-prepared molecules, to study reaction products fully state-specifically, and to derive accurate potential energy surfaces with the goal of determining the pathways along which molecular interaction can take place. Both experimental and theoretical techniques have rapidly improved, and our understanding of the dynamical nature of chemical processes is continuously growing. In this special issue of CAMOP/Physica Scripta we have tried to present a snapshot of the state-of-the-art in the field of molecular dynamics. It contains a collection of papers submitted in association with the most recent MOLEC meeting (MOLEC XV) held in September 2004 in Nunspeet, The Netherlands. This biannual meeting started in 1976 in Trento and was subsequently organized in Brandbjerg Hjskole (Denmark, 1978), Oxford (UK, 1980), Nijmegen (The Netherlands, 1982), Jerusalem (Israel, 1984), Aussois (France, 1986), Assissi (Italy, 1988), Bernkastel-Kues (Germany, 1990), Prague (Czech Republic, 1992), Salamanca (Spain, 1994), Nyborg Strand (Denmark, 1996), Bristol (UK, 1998), Jerusalem (Israel, 2000) and Istanbul (Turkey, 2002). Within the philosophy of CAMOP we have asked invited speakers to report on outstanding problems in their particular field. This comprises discussion of open questions, important applications, new theoretical and experimental approaches and also predictions of future developments. A good comment, in addition to being an authoritative contribution of an acknowledged expert, should also be readable by the non-expert and we have taken special care that the work presented here is introduced in an understandable way and has been placed within the context of accessible literature for the interested reader. The sequence of 16 papers that is presented in this issue is arranged according to three main topics that form a focus within the field and can be roughly summarized as induced chemical (intermolecular) dynamics, molecular spectroscopy/theory, and photo-induced uni-molecular (intramolecular) dynamics. The issue opens with a contribution by the MOLEC XV award winner Levine and his co-workers (the paper by Kornweitz et al) in which they speculate on the possibility of probing electronic rearrangement in a chemical collision using light emitted during the very collision. Banares and co-workers continue with an overview on what is and what is not understood about the dynamics of the `most simple reaction' H + H2 and prospects for future research of this prototypic system are presented. The effect of molecular structure on chemical dynamics is discussed by Pearce \\etal on the example of HCl originating from Cl atoms reacting with different organic ethers. Stereodynamical effects are discussed by Cappelletti and co-workers starting from collisional alignment in supersonic seeded molecular beams with applications ranging from (in)elastic events to selective surface scattering experiments. A laboratory controlled study of chemical reactions under interstellar conditions using temperature variable multi-electrode traps is reviewed by Gerlich and Smith. Eritt \\etal discuss a technique capable of studying the interaction of electrons with size selected molecular ions and results are presented for the electron detachment of Cn- and Aln-clusters. Ultrafast dynamical events at a conical intersection are discussed in a theoretical study by Burghardt et al and the experimental tools to study electron dynamics are presented by Vrakking in a contribution on direct and indirect methods to generate attoseconds. In four spectroscopic and theoretical contributions the latest findings are presented in interpreting and understanding complicated molecular spectra. Meerts and Smit introduce a powerful numerical assign and analysis method based upon genetic algorithms and its performance is demonstrated on the example of dense spectra of (complexed) aromatic species. Interaction potential surface calculations of rare gasses with halogens in van der Waals complexes are described by Delgado-Barrio and co-workers, and Tennyson discusses new theoretical techniques based on the use of the variational principle to guide the spectral assignment of complicated water spectra, e.g. at very high temperatures. Finally, Okumura and co-workers present NIR spectra of NO3 and in combination with new calculations these shed light on how to interpret vibronic couplings in this interesting system. The last section of this issue comprises fragmentation and photo-dissociation studies. Rubio-Lago et al discuss methods to produce high-density spin polarized hydrogen following photodissociation experiments. The photodissociation of HCl and Cl2 is taken as an example by Balint-Kurti et al to demonstrate how amplitudes and phases of the photofragmentation matrix elements are derived from experimental measurements. Directional dynamics in photodissociation processes and the derivation of molecular frame properties are discussed in detail by Van den Brom et al using laboratory oriented molecules. And the issue closes with a contribution by Chambreau et al on different reaction mechanisms in the photodissociation of formaldehyde into H2 and CO. Coming to the end of this editorial, we wish to thank all the authors who participated with their contributions in this issue. It shows what is possible nowadays in the field of molecular dynamics and where things are heading in the near future. We thank Physica Scripta for providing us with the platform for this Special Issue, and we wish you, dear reader, many new insights!

  18. Ground-Water Resource Assessment in the Rio Grande de Manati Alluvial Plain, Rio Arriba Saliente Area, Puerto Rico

    The alluvial aquifer within a 160-acre area of the Rio Grande de Manati alluvial plain was investigated to evaluate its potential as a water-supply source for the Barrios Rio Arriba Saliente and Pugnado Afuera, municipio of Manati, Puerto Rico. Analysis of well boring samples and the results of electric resistivity surveys indicate that the average thickness of the unconsolidated alluvial deposits in the study area is about 100 to 110 feet. The alluvium is a mixture of sand and gravel, which generally has a porosity of 0.2 to 0.35. Short-duration pump tests in small-diameter piezometers indicate that the alluvial aquifer has a hydraulic conductivity of about 200 feet per day and a transmissivity of about 7,900 feet squared per day. Analyses of water levels in piezometers, combined with stage measurements at a series of surveyed reference points along the Rio Grande de Manati channel, indicate that the water-table gradient in the alluvial aquifer is about 0.001, and that ground-water flow is generally from south to north, in the general direction of river flow. The water-table data indicate that the Rio Grande de Manati is the principal source of ground-water recharge to the alluvial aquifer in the study area. Because base flow for the Rio Grande de Manati is usually greater than 44 cubic feet per second, a continuous withdrawal rate of 0.5 to 1.0 cubic foot per second (225 to 450 gallons per minute) from a production well is possible. Chemical analysis of a ground-water sample indicates that the alluvial aquifer water meets U.S. Environmental Protection Agency secondary standards for selected constituents. Bacteriological analysis of ground-water samples indicates that the ground water contains little or no fecal coliform or fecal streptococcus bacteria. Although long-term data from upstream of the study area indicate high levels of fecal coliform and fecal streptococcus prior to 1996, bacteriological analyses of Rio Grande de Manati water samples obtained during the present study indicate that fecal coliform and fecal streptococcus concentrations are within the standards for surface water intended for use (or with the potential for use) as a raw source of public water supply in Puerto Rico. If a production well were constructed in the study area, it would be located close to the river channel (within 500 to 800 feet). Pumping from the porous and permeable alluvial aquifer close to the river channel could substantially enhance recharge from the Rio Grande de Manati channel to the aquifer. Enhanced recharge could shorten travel times for ground water in the aquifer, which might not allow sufficient time to attenuate bacteria and viruses. Travel times for bacteria moving from the river channel to a hypothetical production well were estimated using the numerical transport model MODFLOW/MT3DMS with an uncalibrated model of the alluvial aquifer. The model assumes a well pumping at 1 cubic foot per second. The transport of particles from the river to the well is most sensitive to the porosity of the aquifer and the pumping rate of the well. Sensitivity analysis indicates that a decrease in pumpage will increase the time of travel for particles to move from the river to the pumping well. The model indicates that the leading edge of a plume would reach the production well in about 40 days assuming a porosity of 0.20, 60 days assuming a porosity of 0.275, and about 70 days assuming a porosity of 0.35. If the well were moved 50 feet further from the river, the leading edge of the plume would reach the well in about 50 days assuming a porosity of 0.20 and about 70 days assuming a porosity of 0.275. These estimates are considered worse case estimates because no decay rate was included in the simulation, and because the hypothetical well was located in the center of the alluvial plain rather than further eastward, away from the river channel.

  19. Development of a sharp interface model that simulates coastal aquifer flow with the coupled use of GIS

    NASA Astrophysics Data System (ADS)

    Gemitzi, Alexandra; Tolikas, Demetrios

    A simulation program, which works seamlessly with GIS and simulates flows in coastal aquifers, is presented in the present paper. The model is based on the Galerkin finite element discretization scheme and it simulates both steady and transient freshwater and saltwater flow, assuming that the two fluids are separated by a sharp interface. The model has been verified in simple cases where analytical solutions exist. The simulation program works as a tool of the GIS program, which is the main database that stores and manages all the necessary data. The combined use of the simulation and the GIS program forms an integrated management tool offering a simpler way of simulating and studying saline intrusion in coastal aquifers. Application of the model to the Yermasogia aquifer illustrates the coupled use of modeling and GIS techniques for the examination of regional coastal aquifer systems. Pour étudier un système aquifère côtier, nous avons développé un modèle aux éléments finis en quasi 3-D qui simule les écoulements d'eau douce et d'eau salée en régime aussi bien permanent que transitoire. Les équations qui les régissent sont discrétisées par un schéma de discrétisation de Garlekin aux éléments finis. Le modèle a été vérifié dans des cas simples où il existe des solutions analytiques. Toutes les données nécessaires sont introduites et gérées grâce à un logiciel de gestion de SIG. Le programme de simulation est utilisé comme un outil du logiciel de SIG, constituant ainsi un outil de gestion intégrée dont le but est de simuler et d'étudier l'intrusion saline dans les aquifères côtiers. L'application du modèle à l'aquifère de Yermasogia illustre l'utilisation couplée de la modélisation et des techniques de SIG pour l'étude des systèmes aquifères côtiers régionaux. Se ha desarrollado un modelo casi tridimensional de elementos finitos para simular el flujo de agua dulce y salada, tanto en régimen estacionario como en transitorio, en sistemas acuíferos costeros, bajo la hipótesis de separación por medio de una interfaz abrupta. Las ecuaciones del modelo han sido discretizadas mediante un esquema de Galerkin de discretización en elementos finitos. El modelo ha sido verificado en casos sencillos para los que existe solución analítica. Todos los datos necesarios se introducen y gestionan con un Sistema de Información Geográfica [SIG] por ordenador. El programa de simulación forma parte del programa de SIG, constituyendo una herramienta integrada de gestión para estudiar la intrusión salina en acuíferos costeros. La aplicación del modelo al acuífero de Yermasogia ilustra el uso acoplado de las técnicas de modelación y de SIG con el fin de examinar sistemas acuíferos costeros a escala regional.

  1. Pincharse sin infectarse: estrategias para prevenir la infección por el VIH y el VHC entre usuarios de drogas inyectables

    2011-01-01

    Resumen Objetivo Desde principios de los noventa, en la ciudad de Nueva York se han implementado con éxito programas para reducir la incidencia del virus de la inmunodeficiencia humana (VIH) y, en menor medida, del virus de la hepatitis C (VHC). A pesar de ello, aproximadamente el 70% de los usuario de drogas inyectables (UDI) están infectados por el VHC. Queremos investigar cómo el 30% restante se las ha arreglado para no infectarse. El Staying safe (nombre original del estudio) explora los comportamientos y mecanismos que ayudan a evitar la infección por el VHC y el VIH a largo plazo. Material y métodos Hemos utilizado el concepto de «desviación positiva» aplicado en otros campos de salud pública. Estudiamos las estrategias, prácticas y tácticas de prevención de aquellos UDI que, viviendo en contextos de alta prevalencia, se mantienen sin infectar por VIH y el VHC, a pesar de haberse inyectado heroína durante años. Los resultados preliminares presentados en este artículo incluyen el análisis de las entrevistas realizadas a 25 UDI (17 doble negativos, 3 doble positivos y 5 con infección por el VHC y sin infección por el VIH). Se usaron entrevistas semiestructuradas que exploraban con detalle la historia de vida de los sujetos, incluyendo su consumo de drogas, redes sociales, contacto con instituciones, relaciones sexuales y estrategias de protección y vigilancia. Resultados La intencionalidad es importante para no infectarse, especialmente durante períodos de involución (períodos donde hay un deterioro económico y/o social que llevan al que se inyecta a situaciones de mayor riesgo).

    OBJETIVO: Desde principios de los noventa, en la ciudad de Nueva York se han implementado con éxito programas para reducir la incidencia del virus de la inmunodeficiencia humana (VIH) y, en menor medida, del virus de la hepatitis C (VHC). A pesar de ello, aproximadamente el 70% de los usuario de drogas inyectables (UDI) están infectados por el VHC. Queremos investigar cómo el 30% restante se las ha arreglado para no infectarse. El Staying safe (nombre original del estudio) explora los comportamientos y mecanismos que ayudan a evitar la infección por el VHC y el VIH a largo plazo. MATERIAL Y M#ENTITYSTARTX000E9;TODOS: Hemos utilizado el concepto de «desviación positiva» aplicado en otros campos de salud pública. Estudiamos las estrategias, prácticas y tácticas de prevención de aquellos UDI que, viviendo en contextos de alta prevalencia, se mantienen sin infectar por VIH y el VHC, a pesar de haberse inyectado heroína durante años. Los resultados preliminares presentados en este artículo incluyen el análisis de las entrevistas realizadas a 25 UDI (17 doble negativos, 3 doble positivos y 5 con infección por el VHC y sin infección por el VIH). Se usaron entrevistas semiestructuradas que exploraban con detalle la historia de vida de los sujetos, incluyendo su consumo de drogas, redes sociales, contacto con instituciones, relaciones sexuales y estrategias de protección y vigilancia. RESULTADOS: La intencionalidad es importante para no infectarse, especialmente durante períodos de involución (períodos donde hay un deterioro económico y/o social que llevan al que se inyecta a situaciones de mayor riesgo). Presentamos tres dimensiones independientes de intencionalidad que conllevan comportamientos que pueden ayudar a prevenir la infección: a) evitar «el mono» (síntomas de abstención) asegurando el acceso a la droga; b) «llevarlo bien» para no convertirse en un junkie y así evitar la «muerte social» y la falta de acceso a los recursos, y c) seguir sin infectarse por el VIH (sólo un doble negativo tuvo un amplio conocimiento sobre la hepatitis C).

    Biodiversity indices often combine data from different species when used in monitoring programs. Heuristic properties can suggest preferred indices, but we lack objective ways to discriminate between indices with similar heuristics. Biodiversity indices can be evaluated by determining how well they reflect management objectives that a monitoring program aims to support. For example, the Convention on Biological Diversity requires reporting about extinction rates, so simple indices that reflect extinction risk would be valuable. We developed 3 biodiversity indices that are based on simple models of population viability that relate extinction risk to abundance. We based the first index on the geometric mean abundance of species and the second on a more general power mean. In a third index, we integrated the geometric mean abundance and trend. These indices require the same data as previous indices, but they also relate directly to extinction risk. Field data for butterflies and woodland plants and experimental studies of protozoan communities show that the indices correlate with local extinction rates. Applying the index based on the geometric mean to global data on changes in avian abundance suggested that the average extinction probability of birds has increased approximately 1% from 1970 to 2009. Conectando Índices para el Monitoreo de la Biodiversidad con la Teoría de Riesgo de Extinción Resumen Los índices de biodiversidad combinan frecuentemente los datos de diferentes especies cuando se usan en los programas de monitoreo. Las propiedades heurísticas pueden sugerir índices preferidos, pero carecemos de medios objetivos para discriminar a los índices con propiedades heurísticas similares. Los índices de biodiversidad pueden evaluarse al determinar qué tan bien reflejan los objetivos de manejo que un programa de monitoreo busca apoyar. Por ejemplo, la Convención sobre la Diversidad Biológica requiere reportar las tasas de extinción, así que los índices que reflejan el riesgo de extinción serían valiosos. Desarrollamos 3 índices de biodiversidad que se basan en modelos sencillos de viabilidad de población y que relacionan el riesgo de extinción con la abundancia. Basamos el primer índice en la media geométrica de la abundancia de especies, y el segundo en una media de poder más general. En el tercer índice integramos la media geométrica y la tendencia. Estos índices requieren los mismos datos que índices previos, pero también se relacionan directamente con el riesgo de extinción. La información de campo sobre mariposas y plantas de bosque, y los estudios experimentales de comunidades protozoarias, muestran que los índices se correlacionan con las tasas locales de extinción. Al aplicar el índice basado en la media geométrica sobre los datos globales de los cambios en la abundancia de aves, sugirió que la probabilidad de extinción promedio de aves ha incrementado aproximadamente 1% desde 1970 hasta 2009.

    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. Moreover, the model captures quite well the temperatures in the extreme cold episodes. Acknowledgement.

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 present work was carried out in the frame of the international field campaign DAURE (Determination of the sources of atmospheric Aerosols in Urban and Rural Environments in the western Mediterranean). The objective of this campaign is to study the aerosol pollution episodes occurring at regional scale during winter and summer in the Western Mediterranean Basin. As part of this campaign, this work focuses on identifying the origin of fine carbonaceous aerosols. To this end, fine particulate matter (PM1) samples were collected during two different seasons (February-March and July 2009) at two sites: an urban site (Barcelona, NE Spain) and a rural European Supersite for Atmospheric Aerosol Research (Montseny, NE Spain). Subsequently, 14C analyses were carried out on these samples, both in the elemental carbon (EC) fraction and the organic carbon (OC) fraction, in order to distinguish between modern carbonaceous sources (biogenic emissions and biomass burning emissions) and fossil carbonaceous sources (mainly road traffic). Preliminary results from the winter period show that 40% of the OC at Barcelona has a fossil origin whereas at Montseny this percentage is 30%. These values can be considered as unexpected given the nature of the sites. Nevertheless, the absolute concentrations of fossil OC at Barcelona and Montseny differ by a factor of 2 (the first being higher), since the total OC at Montseny is lower than at Barcelona. Further evaluation of results and comparison with other measurements carried out during the campaign are required to better evaluate the origin of the fine carbonaceous matter in the Western Mediterranean Basin.

    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.

    Toxic oil syndrome (TOS) resulted from consumption of rapeseed oil denatured with 2% aniline and affected more than 20,000 persons. Eighteen years after the epidemic, many patients continue to report neurologic symptoms that are difficult to evaluate using conventional techniques. We conducted an epidemiologic study to determine whether an exposure to toxic oil 18 years ago was associated with current adverse neurobehavioral effects. We studied a case group of 80 adults exposed to toxic oil 18 years ago and a referent group of 79 adult age- and sex-frequency-matched unexposed subjects. We interviewed subjects for demographics, health status, exposures to neurotoxicants, and responses to the Kaufman Brief Intelligence Test (K-BIT), Programa Integrado de Exploracion Neuropsicologica (PIEN), and Goldberg depression questionnaires and administered quantitative neurobehavioral and neurophysiologic tests by computer or trained nurses. The groups did not differ with respect to educational background or other critical variables. We examined associations between case and referent groups and the neurobehavioral and neurophysiologic outcomes of interest. Decreased distal strength of the dominant and nondominant hands and increased vibrotactile thresholds of the fingers and toes were significantly associated with exposure to toxic oil. Finger tapping, simple reaction time latency, sequence B latency, symbol digit latency, and auditory digit span were also significantly associated with exposure. Case subjects also had statistically significantly more neuropsychologic symptoms compared with referents. Using quantitative neurologic tests, we found significant adverse central and peripheral neurologic effects in a group of TOS patients 18 years after exposure to toxic oil when compared with a nonexposed referent group. These effects were not documented by standard clinical examination and were found more frequently in women. PMID:12896854

    The relevance of Science and Technology in our daily routines makes it compulsory to educate citizens who have both scientific literacy and scientific knowledge. These will allow them to be intervening citizens in a constantly changing society. Thus, physical and natural sciences are included in school curricula, both in primary and secondary education, with the fundamental aim of developing in the students the skills, attitudes and knowledge needed for the understanding of the planet Earth and its real problems. On the other hand, teaching in Geosciences is more and more based on practical methodologies which use didactic material, sustaining teachers' pedagogical practices and facilitating students' learning tasks suggested on the syllabus defined for each school level. Themes related to exploring the different components of the Hydrological Cycle and themes related to natural environment protection and preservation, namely water resources and soil contamination by industrial and urban sewage are examples of subject matters included on the Portuguese syllabus. These topics motivated the conception and construction of experimental models for the study of the propagation of pollutants on a porous medium. The experimental models allow inducing a horizontal flux of water though different kinds of permeable substances (e.g. sand, silt), with contamination spots on its surface. These experimental activities facilitate the student to understand the flow path of contaminating substances on the saturated zone and to observe the contaminant plume configuration and movement. The activities are explored in a teaching and learning process perspective where the student builds its own knowledge through real question- problem based learning which relate Science, Technology and Society. These activities have been developed in the framework of project ‘Water in the Environment' (CV/PVI/0854) of the POCTI Program (Programa Operacional "Ciência, Tecnologia, Inovação") financed by the Portuguese Fundation for Science and Tecnology and FEDER Program.

    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.

Cesco (El Leoncito), gracias al esfuerzo de la gente del Max Planck Institut für Aeronomie (Alemania), del OAFA y del IAFE. Dicho coronógrafo forma parte de un programa de ciencia bilateral entre Alemania y Argentina. El propósito del mismo, en conjunción con otros telescopios solares y terrestres, es contribuir a un mejor entendimiento de cuestiones fundamentales de la física solar. Para ello, ya está observando la corona de emisión en el verde (Fe XIV), rojo (Fe X) y Hα entre 1.05 y 2 radios solares aproximadamente. El diseño del instrumento, el cual fuera ya presentado en esta misma reunión en La Plata en 1996, es esencialmente similar al del telescopio LASCO-C1 a bordo del Solar Heliospheric Observatory (SOHO). La adquisición de datos se realiza con un CCD de 1280x1024 pixels, codificando en 12 bits, pudiendo ser el mismo operado en forma remota. En esta reunión presentaremos algunas de las observaciones realizadas durante la puesta a punto del instrumento en el período julio-setiembre de 1997. Asimismo expondremos cómo y por qué sus resultados complementarán a los de su par en el espacio.

    SummaryIncreased stormflow in the Quebrada Estero watershed (2.5 km 2), in the northwestern Central Valley tectonic depression of Costa Rica, reportedly has caused flooding of the city of San Ramón in recent decades. Although scientifically untested, urban expansion was deemed the cause and remedial measures were recommended by the Programa de Investigación en Desarrollo Humano Sostenible (ProDUS). CASC2D, a physically-based, spatially explicit hydrologic model, was constructed and calibrated to a June 10th 2002 storm that delivered 110.5 mm of precipitation in 4.5 h visibly exceeded the bankfull stage (0.9 m) of the Quebrada flooding portions of San Ramón. The calibrated hydrograph showed a peak discharge 16.68% (2.5 m 3 s -1) higher, an above flood stage duration 20% shorter, and time to peak discharge 11 min later than the same observed discharge hydrograph characteristics. Simulations of changing land cover conditions from 1979 to 1999 showed an increase also in the peak discharge, above flood stage duration, and time to peak discharge. Analysis using a modified location quotient identified increased urbanization in lower portions of the watershed over the time period studied. These results suggest that increased urbanization in the Quebrada Estero watershed have increased flooding peaks, and durations above threshold, confirming the ProDUS report. These results and the CASC2D model offer an easy-to-use, pragmatic planning tool for policymakers in San Ramón to assess future development scenarios and their potential flooding impacts to San Ramón.

    Changes in the availability of fresh water caused by climatic changes will become a major issue in the coming years and decades. In this context, regions presently depending on water from retreating mountain glaciers are particularly vulnerable. In many parts of the Andes for example, people already suffer from the impacts of reduced glacier run off. Therefore, the development and implementation of adequate adaptation measures is an urgent need. To better understand the impact of climate change on water resources in the Andean region, a new research program (PACC - Programa de Adaptación al Cambio Climático en el Perú) between Peru and Switzerland has recently been launched by SDC (Swiss Agency for Development and Cooperation). As a first step, a scientific baseline relative to climatology, hydrology, agriculture and natural disasters will be developed on a regional scale for the Departments of Cusco and Apurimac in close cooperation with partners from Universities and governmental institutions as well as NGOs in Peru. A reliable data baseline is a must for the development of adaptation measures that can effectively cope with the risks induced by climate change. The realization of this task in remote mountain regions, where observational data are generally sparse, however, is challenging. Temporal and spatial gaps must be filled using indirect methods such as re-analyses, remote sensing and interpolation techniques. For future scenarios, the use of climate model output along with statistical and dynamical downscaling is indicated. This contribution will present and discuss approaches and possible concepts to tackle the challenges in a Peruvian context. In addition, first experiences will be reported particularly on cross-disciplinary issues that naturally emerge from the integrative perspective needed in climate change impact assessments and the development of adaptation strategies.

  19. Onshore wind energy potential over Iberia: present and future projections

    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.

    A "learning health care system", as outlined in a recent Institute of Medicine report, harnesses real-time clinical data to continuously measure and improve clinical care. However, most current efforts to understand and improve the quality of care rely on retrospective chart abstractions complied long after the provision of clinical care. To align more closely with the goals of a learning health care system, we present the novel design and initial results of the Veterans Affairs (VA) Clinical Assessment, Reporting, and Tracking (CART) program-a national clinical quality program for VA cardiac catheterization laboratories that harnesses real-time clinical data to support clinical care and quality-monitoring efforts. Integrated within the VA electronic health record, the CART program uses a specialized software platform to collect real-time patient and procedural data for all VA patients undergoing coronary procedures in VA catheterization laboratories. The program began in 2005 and currently contains data on 434,967 catheterization laboratory procedures, including 272,097 coronary angiograms and 86,481 percutaneous coronary interventions, performed by 801 clinicians on 246,967 patients. We present the initial data from the CART program and describe 3 quality-monitoring programs that use its unique characteristics-procedural and complications feedback to individual labs, coronary device surveillance, and major adverse event peer review. The VA CART program is a novel approach to electronic health record design that supports clinical care, quality, and safety in VA catheterization laboratories. Its approach holds promise in achieving the goals of a learning health care system. PMID:25439452

Methods A paired cross-sectional birth observation study was conducted with a convenience sample of 18 clinics (nine pairs of intervention and control clinics) from June 28 to August 7, 2013. Outcomes included implementation of practices known to decrease maternal and/or neonatal mortality and improve patient care. Results Overall, 25 and 17 births occurred in intervention and control clinics, respectively. Active management of the third stage of labor was appropriately performed by 20 (83%) of 24 intervention teams versus 7 (50%) of 14 control teams (P = 0.015). Intervention teams implemented more practices to decrease neonatal mortality than did control teams (P < 0.001). Intervention teams ensured patient privacy in 23 (92%) of 25 births versus 11 (65%) of 17 births for control teams (P = 0.014). All 15 applicable intervention teams kept patients informed versus 6 (55%) of 11 control teams (P = 0.001). Differences were also noted in teamwork; in particular, skill-based tools were used more often at intervention sites than control sites (P = 0.012). Conclusion Use of PRONTO enhanced non-emergency delivery care by increasing evidence-based practice, patient-centered care, and teamwork. PMID:26797198

    Objective : To present the Programa Infantil de Prevenção de Asma (PIPA, Program for the Prevention of Childhood Asthma) and the characteristics of the patients followed in this program. Methods : Implemented in the city of Uruguaiana, Brazil, PIPA has as its target population children and adolescents (< 18 years of age) with asthma or suspected asthma. Patients either enroll in PIPA spontaneously or are referred by pediatricians or primary care physicians. In this retrospective study, we use a standardized protocol to assess PIPA patients. Results : By the end of the study period, 646 patients were being followed. Of those, 298 (46.1%) were ≤ 3 years of age. In this group of patients, recurrent wheezing was identified in 60.7%, and the first episode of wheezing occurred in the first six months of life in 86.0%. Severe wheezing was identified in 29.5% and 45.4% in the children ≤ 3 and > 3 years of age, respectively. Physician-diagnosed asthma was reported in 26.5% and 82.2%, respectively. In the sample as a whole, the prevalence of passive smoking was high (> 36%), occurring during pregnancy in > 15%; > 40% of the patients had been born by cesarean section; and 30% had a mother who had had < 8 years of schooling. Conclusions : A prevention program for children with asthma is an effective strategy for controlling the disease. Knowledge of local epidemiological and environmental characteristics is essential to reducing the prevalence of the severe forms of asthma, to improving the use of health resources, and to preventing pulmonary changes that could lead to COPD in adulthood.

    Background Anastrepha ludens is among the pests that have a major impact on México's economy because it attacks fruits as citrus and mangoes. The Mexican Federal government uses integrated pest management to control A. ludens through the Programa Nacional Moscas de la Fruta [National Fruit Fly Program, SAGARPA-SENASICA]. One of the main components of this program is the sterile insect technique (SIT), which is used to control field populations of the pest by releasing sterile flies. Results To increase the efficiency of this technique, we have developed a genetic sexing strain (GSS) in which the sexing mechanism is based on a pupal colour dimorphism (brown-black) and is the result of a reciprocal translocation between the Y chromosome and the autosome bearing the black pupae (bp) locus. Ten strains producing wild-type (brown pupae) males and mutant (black pupae) females were isolated. Subsequent evaluations for several generations were performed in most of these strains. The translocation strain named Tapachula-7 showed minimal effect on survival and the best genetic stability of all ten strains. Genetic and cytogenetic analyses were performed using mitotic and polytene chromosomes and we succeeded to characterize the chromosomal structure of this reciprocal translocation and map the autosome breakpoint, despite the fact that the Y chromosome is not visible in polytene nuclei following standard staining. Conclusions We show that mitotic and polytene chromosomes can be used in cytogenetic analyses towards the development of genetic control methods in this pest species. The present work is the first report of the construction of GSS of Anastrepha ludens, with potential use in a future Moscafrut operational program. PMID:25472896

    In-Plant Training (INPLT) is a new model for developing energy efficiency expertise within the US manufacturing companies participating in the U.S. Department of Energy s (DOE s) Better Buildings, Better Plants Program-a nationwide initiative to drive a 25% reduction in industrial energy intensity in 10 years. INPLTs are designed to fill a market niche by providing hands on training in a real world manufacturing plant environment. Through INPLTs, participants from multiple manufacturing plants, supply chains, utilities, and other external stakeholders learn how to conduct energy assessments, use energy analysis tools to analyze energy saving opportunities, develop energy management systems, and implement energy savings projects. Typical INPLT events are led by DOE-certified Energy Experts and range from 2-4 days. Topics discussed include: identification of cross-cutting or system specific opportunities; introduction to ISO 50001 Energy Management Systems; and energy project implementation and replication. This model is flexible, and can be tailored to suit the needs of specific industries. The INPLTs are a significant departure from the traditional single plant energy assessment model previously employed by DOE. INPLTs shift the focus from the concept of a single-plant s energy profile to a broader focus on training and capacity building among multiple industrial participants. The objective is to enable trainees to identify, quantify, implement and replicate future energy saving projects without continued external assistance. This paper discusses the INPLT model and highlights some of the initial outcomes from the successfully delivered INPLTs and the overall impact in terms of numbers of plants/participants trained, impacted energy footprints, and potential replication of identified opportunities.
