    Camino Verde (the Green Way) is an evidence-based community mobilisation tool for prevention of dengue and other mosquito-borne viral diseases. Its effectiveness was demonstrated in a cluster-randomised controlled trial conducted in 2010-2013 in Nicaragua and Mexico. The Nicaraguan arm of the trial was preceded, from 2004 to 2008, by a feasibility study that provided valuable lessons and trained facilitators for the trial itself. Here, guided by the Template for Intervention Description and Replication (TIDieR), we describe the Camino Verde intervention in Nicaragua, presenting its rationale, its time and location, activities, materials used, the main actors, modes of delivery, how it was tailored to encourage community engagement, modifications made from the feasibility study to the trial itself, and how fidelity to the process originally designed was maintained. We also present information on costs and discuss the place of this study within the literature on implementation science. ISRCTN27581154 .

    Humans travel for many reasons; here we concentrate in pilgrimage and the role of the Ebro River as their means of transportation. The Camino de Santiago through the Ebro is linked to the devotion to Santa María del Pilar de Zaragoza, where according to the tradition appeared in flesh and body (January 2, 40, BC). Famous pilgrims are Luis VII of France, Lady Blanca, daughter of Carlos III. The Ebro's navigability allowed sustaining the fervor alive as it is proven by the many records found Catón, Estrabrón, Plinio, Avieno) describing its use for pilgrimage and commercial purposes.

    1998-01-01

    Intracranial pressure monitoring has a key role in the management of patients developing increased intracranial pressure (ICP). We adopted the Camino fiberoptic system for intracranial pressure measurement in 1993 in our neurosurgical department. The aim of this study was to investigate reliability, handling characteristics and complication rate of the Camino intracranial pressure device. In an eighteen month period, we prospectively investigated 118 patients with intracranial pathology undergoing Camino fiberoptic intraparenchymal or intraventricular ICP monitoring. The assessment of reliability of ICP monitoring according to patients clinical condition, to cranial computed tomography (CCT) findings and ICP waveform was carried out. Position of the probe and intracranial bleeding complications related to probe insertion were confirmed by CCT. Technical complications, as well as infections due to the device, were documented. In vivo recalibration was performed in 22 patients. At the end of the measuring period the drift of the probe was evaluated and the accuracy of the fiberoptic device was measured by performing a two point calibration. Recordings of intracranial pressure were carried out with 136 Camino devices (104 parenchymal, 32 ventricular) in 118 patients with an average measuring time of 94.1 +/- 79.1 hrs. One hundred and fifteen Camino intracranial pressure devices (85.2%) demonstrated reliability according to the predetermined clinical parameters. The actual mean drift after removal of the devices was 3.4 mmHg +/- 3.2 with an actual daily drift of 3.2 +/- 17.2 mmHg. Recorded complications included infection (0.7%), intraparenchymal haematoma (5.1%), and a high complication rate (23.5%) with regard to technical aspects. The Camino intracranial pressure system offers reliable ICP measurements in an acceptable percentage of devices, and the advantage of in vivo recalibration. The high incidence of technical complications identifies a need for improvement in

    Intracranial pressure (ICP) monitoring has become standard in the management of neurocritical patients. A variety of monitoring techniques and devices are available, each offering advantages and disadvantages. Analysis of large populations has never been performed. A prospective study was designed to evaluate the Camino fiberoptic intraparenchymal cerebral pressure monitor for complications and accuracy. Between 1992-2004 one thousand consecutive patients had a fiberoptic ICP monitor placed. The most frequent indication for monitoring was severe head injury (697 cases). The average duration of ICP monitoring was 184.6 +/- 94.3 hours; the range was 16-581 hours. Zero drift (range, -17 to 21 mm Hg; mean 7.3 +/- 5.1) was recorded after the devices were removed from 624 patients. Mechanical complications such as: breakage of the optical fiber (n = 17); dislocations of the fixation screw (n = 15) or the probe (n = 13); and failure of ICP recording for unknown reasons (n = 4) were found in 49 Camino devices. The Camino ICP sensor remains one of the most popular ICP monitoring devices for use in critical neurosurgical patients. The system offers reliable ICP measurements in an acceptable percentage of device complications and the advantage of in vivo recalibration. The incidence of technical complications was low and similar to others devices.

    2005-10-01

    El Camino Hospital is a leader in the use of health information technology to promote patient safety, including bar coding, computerized order entry, electronic medical records, and wireless communications. Each year, El Camino Hospital's board of directors sets performance expectations for the chief executive officer, which are tied to achievement of local, regional, and national safety and quality standards, including the six Institute of Medicine quality dimensions. He then determines a set of explicit quality goals and measurable actions, which serve as guidelines for the overall hospital. The goals and progress reports are widely shared with employees, medical staff, patients and families, and the public. For safety, for example, the medication error reduction team tracks and reviews medication error rates. The hospital has virtually eliminated transcription errors through its 100% use of computerized physician order entry. Clinical pathways and standard order sets have reduced practice variation, providing a safer environment. Many projects focused on timeliness, such as emergency department wait time, lab turnaround time, and pneumonia time to initial antibiotic. Results have been mixed, with projects most successful when a link was established with patient outcomes, such as in reducing time to percutaneous transluminal coronary angioplasty for patients with acute myocardial infarction.

  10. Comparison of simultaneous continuous intracranial pressure (ICP) signals from a Codman and a Camino ICP sensor.

    Eide, Per Kristian

    2006-07-01

    Simultaneous continuous intracranial pressure (ICP) signals from two different sensors were compared. Continuous ICP monitoring from two ICP sensors (i.e. Codman ICP MicroSensor; Johnson & Johnson, Raynham, MA and Camino OLM ICP; Camino Laboratories, San Diego, CA) placed within the brain parenchyma was performed in three patients within the intensive care unit (ICU) as part of routine management of severe subarachnoid hemorrhage. For each 6s time window mean ICP was computed, showing large differences in mean ICP values between the signals. Differences above 5 mmHg were observed in 13% of the 128,425 time windows derived from 214 h ICP recordings in these three patients. In one patient, mean ICP differed more than 10 mmHg in 23% of the time windows. Comparisons of 675,503 individual single pressure wave pairs of these 128,425 time windows revealed marginal differences in single wave amplitude (dP, i.e. pulse pressure) and latency (dT, i.e. rise time) values, suggesting that differences in mean ICP were caused by differences in baseline pressure. For the individual time windows were computed the mean wave amplitude and mean wave latency values according to a new algorithm. There were as well marginal differences between signals of mean wave amplitude and latency values. Thus, changes in baseline pressure affect mean ICP but not single pressure wave characteristics such as amplitude (dP) and (dT) latency values.

    Coca, S.; Rohrmann, R.

    El exceso de emisión infrarroja en objetos protoestelares es atribuido usualmente a un disco de material en torno al cuerpo central. A pesar del avance alcanzado en la elaboración de modelos, aún existen dificultades para explicar la ley de temperatura del disco necesaria para reproducir las luminosidades y perfiles de energía observados. Nuestra propuesta consiste en determinar la distribución espectral de la radiación derivada de un particular modelo de colapso protoestelar, y estudiar la evolución del espectro desde estadíos tempranos de la contracción gravitatoria. Este plan es orientado a evaluar las propiedades del modelo (distribuciones de masa y temperatura del material circunestelar) por comparación con datos observacionales, a fin de inferir de ello los posibles ajustes requeridos en la teoría actualmente empleada.

    2004-01-01

    This study describes the experiences of two mothers of Mexican origin who are immigrants living under undocumented status in the United States and who participated in their children's early intervention programs. In-depth interviews, archival data, and participant observation conducted with two mothers of children with special needs provided data for this case study design research. A phenomenological analytical approach and qualitative data analysis software were employed to gain understandings particular to each family's experience. These families share similar experiences and interactions with many other families in the United States who live within the context of having a child with a disabling condition. Constraints on family functioning related to the families' status of undocumented immigration included: mothers as active participants in their children's early intervention programs, mothers' understanding of their children, mothers' communication with service providers, and life as an immigrant family of Mexican origin living under undocumented status. The examination of how these mothers negotiated family life while participating in their child's early intervention program provides an appreciation for how these families view the long road--"mucho camino"--involved in achieving their family's well-being.

    Recent literature on community intervention research stresses system change as a condition for durable impact. This involves highly participatory social processes leading to behavioural change. Before launching the intervention in the Nicaraguan arm of Camino Verde, a cluster-randomised controlled trial to show that pesticide-free community mobilisation adds effectiveness to conventional dengue controls, we held structured discussions with leaders of intervention communities on costs of dengue illness and dengue control measures taken by both government and households. These discussions were the first step in an effort at Socialising Evidence for Participatory Action (SEPA), a community mobilisation method used successfully in other contexts. Theoretical grounding came from community psychology and behavioural economics. The leaders expressed surprise at how large and unexpected an economic burden dengue places on households. They also acknowledged that large investments of household and government resources to combat dengue have not had the expected results. Many were not ready to see community preventive measures as a substitute for chemical controls but all the leaders approved the formation of "brigades" to promote chemical-free household control efforts in their own communities. Discussions centred on household budget decisions provide a good entry point for researchers to engage with communities, especially when the evidence showed that current expenditures were providing a poor return. People became motivated not only to search for ways to reduce their costs but also to question the current response to the problem in question. This in turn helped create conditions favourable to community mobilisation for change. ISRCTN27581154 .

    Intracranial pressure (ICP) monitoring is a mainstay in the management of traumatic brain injury. Large investigations have validated the safety and efficacy of ICP monitors in comatose patients. Clinically relevant infections are extremely rare and cerebral abscess has never been reported with the Camino device. We describe an exceptional case of a life-threatening intracerebral abscess from an intraparenchymal ICP monitor. A 35-month-old child required 7 days of ICP monitoring after a fall from a 2-story window. His hospital course was complicated by severe airway edema treated, in part, with high-dose corticosteroid therapy for a total of 10 days. Two weeks later, the patient deteriorated acutely owing to a large intracerebral abscess under the previous ICP monitor site. Urgent craniotomy with evacuation of the abscess was performed on 2 separate occasions. Cultures grew methicillin-sensitive Staphylococcus aureus, which was treated with long-term antibiotics. At the 3-month follow-up, the patient was meeting age-appropriate milestones without focal deficits. To the best of our knowledge, this is the first report describing an intracerebral abscess as a complication from an intraparenchymal pressure monitor. Corticosteroid therapy may have constituted an independent risk factor for the ICP monitor--associated infection, as well as reinsertion of the ICP monitoring device at the same site. That this is the first reported parenchymal infectious complication underscores the safety of this device with respect to infection. When reinsertion of a parenchymal monitor is considered, a new site should be chosen.

    2006-07-01

    Healthy Weigh (El camino saludable) is an obesity prevention program for low-income, predominantly Hispanic and African American families in an urban community in Tarrant County, Texas. Healthy Weigh Phase 1 was a successful community-campus partnership that took place in summer (June-August) and fall (September-November) 2003. The program met stated objectives and extensively engaged students from several health disciplines in service learning. This article describes what we learned about the evaluation of the program by examining the phase 1 evaluation process. Family environments are important intervention settings for establishing life-long dietary practices. Available in English and Spanish, Healthy Weigh Phase 1 helped families that were at risk for overweight and obesity to adopt healthy eating, physical activity, and weight management patterns. Analysis of a program logic model and formative evaluation data identified evaluation questions that could have improved the phase 1 evaluation process. Questions were categorized according to Donabedian's structure-process-outcome framework, and potential benefits of each question were identified. The Centers for Disease Control and Prevention's Framework for Program Evaluation in Public Health standards were used to judge the overall quality of the phase 1 evaluation process. The phase 1 evaluation process successfully assessed the program's effects and generally met evaluation standards. Our critical examination also highlighted structure and process evaluation issues with potential for strengthening future interventions, community partnerships, and program outcomes. Lessons learned influenced the phase 2 grant activities. Most importantly, we learned that involvement of program participants as full partners in program design, evaluation, and implementation is essential. Our understanding and practice of program evaluation evolved as Healthy Weigh became a true community-based participatory research endeavor.

  4. En la búsqueda de características en eyecciones coronales de masa que discriminen entre dos paradigmas físicos en modelos de ECMs

    NASA Astrophysics Data System (ADS)

    Paissan, G.; Stenborg, G.; Rovira, M.

    Se conocen tres diferentes fenómenos de gran escala que ocurren en la atmósfera solar, denominados eyecciones coronales de masa (ECMs), protuberancias eruptivas y grandes fulguraciones de dos bandas. Estos fenómenos están estrechamente relacionados y podrían ser distintas manifestaciones de un único proceso físico. Las ECMs son definidas como eyecciones de gran escala de masa y flujo magnético desde la baja corona al espacio interplanetario. Desde su descubrimiento en los '70, muchos modelos han sido propuestos para explicar su origen y evolución. La explicación física de las ECMs es un tema de debate intenso. No obstante, los modelos pueden sintetizarse en dos grandes grupos: 1) los modelos de inyección de flujo y 2) los modelos de almacenamiento y liberación. En este trabajo, se presentan los estudios realizados con una serie de eventos observados con el coronógrafo MICA (Mirror Coronograph for Argentina), el telescopio en H-alfa HASTA (H-alpha Solar Telescope for Argentina) y los coronógrafos C2 y C3 de la sonda SOHO (Solar and Heliospheric Observatory). Los eventos que pudieron ser identificados como ECMs son contrastados dentro del esquema de los dos paradigmas teóricos propuestos.

    Cirigliano, D.; Rovira, M.; Mauas, P.

    En este trabajo presentamos perfiles de líneas del CaII, MgII y HeI calculados para distintos modelos de protuberancias, y los comparamos con observaciones obtenidas por los satélites OSO 8 y SOHO. Para obtener las poblaciones de los distintos niveles de los átomos, utilizamos un código numérico que combina las ecuaciones de transporte de radiación y equilibrio estadístico en un único sistema de ecuaciones no lineal. Los modelos básicos que consideramos para las protuberancias consisten en placas homogéneas y unidimensionales apoyadas sobre la superficie del Sol. Dichas placas se hallan estratificadas en hebras y los modelos difieren entre sí en la temperatura y ancho de la placa, en la presión a la cual se halla el plasma y en el número de hebras. A partir de estos modelos se investiga cada uno de estos parámetros libres y como influyen en la atmósfera de las protuberancias solares y en el perfil de línea de cada especie estudiada, con el objetivo de determinar las condiciones en las que se halla el material atmosférico de estas protuberancias.

    To assess the safety and accuracy of the Camino intraparenchymal sensor, we prospectively evaluated hemorrhagic complications, zero-drift, infection, and system malfunction in 163 patients monitored after a severe head injury. Mean duration of intracranial pressure (ICP) monitoring was 5 +/- 2.2 days (range: 12 h to 11 days). Of the 141 patients with a control CT scan, four showed a 1-2-cc collection of blood at the catheter's end. When removed, the sensors underread the true ICP value (negative zero-drift) in 80 of the 126 sensors evaluated (63.5%). Fourteen sensors showed no zero-drift, and 32 sensors overread the true ICP value (positive zero-drift) (median: -1 mm Hg; interquartile range: -4 to +1 mm Hg). No significant relationship was found between zero-drift, the surgeon who implanted the sensor, intracranial hypertension, or duration of ICP monitoring. No clinical infections could be attributed to the devices. Sixteen patients (9.8%) required more than one ICP sensor due to malfunctioning of the system. In conclusion, continuous ICP monitoring using the Camino intraparenchymal sensor has a low complication rate. However, this sensor may underread the real ICP values in a high number of patients. The lack of correlation between duration of ICP monitoring and zero-drift suggests that, contrary to the recommendations of other reports, the intraparenchymatous Camino sensor can provide reliable readings after the fifth day of use.

    To audit the reliability of the Camino intracranial pressure (ICP) sensor (Camino Laboratories, San Diego, CA) in our clinical practice as part of a continuing quality assurance program, and to assess its relative usefulness as compared with currently available ICP monitoring technologies that we reviewed. Prospective audit of ICP device reliability and function in 50 patients with head injuries. Zero drift was recorded immediately after the ICP device was removed from the patient. Dynamic frequency response bench testing of each functioning catheter from 0 to 30 Hz and static calibration testing from 0 to 100 mmHg during environmental temperature variation from 22 to 40 degrees C were carried out. Zero drift (range, -13 to 22 mmHg; median, -1 mmHg) was recorded immediately after the devices were removed from patients. Seventeen (50%) of the devices tested for zero drift had absolute drifts of at least 3 mmHg. There was no correlation between recorded zero drift and duration of monitoring (r = 0.154, P = 0.207). Five sensors (10% of those tested) failed during patient monitoring and were replaced. Static and dynamic calibration tests of the functioning sensors were within the manufacturer's specifications. However, the sensitivity of the devices to environmental temperature remains a problem. The Camino ICP sensor remains one of the most popular ICP monitoring devices for use in patients with traumatic brain injuries. However, our recent in-house assessment demonstrated the robustness of the device to be less than adequate during routine practice. In this study, more than 50% exhibited zero drift greater than 3 mmHg, which is unacceptable in a catheter tip ICP monitoring device in which zero drift and calibration cannot be checked in vivo. A review of the literature revealed that other available ICP monitoring devices may prove to be more reliable and thus more appropriate for routine clinical measurement of ICP.

    Studies in different countries have identified irregular water supply as a risk factor for dengue virus transmission. In 2013, Camino Verde, a cluster-randomised controlled trial in Managua, Nicaragua, and Mexico's Guerrero State, demonstrated impact of evidence-based community mobilisation on recent dengue infection and entomological indexes of infestation by Aedes aegypti mosquitoes. This secondary analysis of data from the trial impact survey asks: (1) what is the importance of regular water supply in neighbourhoods with and without the trial intervention and (2) can community interventions like Camino Verde reasonably exclude households with adequate water supply? Entomological data collected in the dry season of 2013 in intervention and control communities allow contrasts between households with regular and irregular water supplies. Indicators of entomological risk included the House Index and pupa positive household index. Generalised linear mixed models with cluster as a random effect compared households with and without regular water, and households in intervention and control communities. For the House Index, regular water supply was associated with a protection in both intervention households (OR 0.7, 95%CI 0.6-0.9) and control households (OR 0.6, 95%CI 0.5-0.8). For the pupa positive household index, we found a similar protection from regular water supply in intervention households (OR 0.6, 95%CI 0.4-0.8) and control households (OR 0.7, 95%CI 0.5-0.9). The Camino Verde intervention had a similar impact on House Index in households with regular water supply (OR 0.7, 95%CI 0.5-1.0) and irregular water supply (OR 0.6, 95%CI 0.4-0.8); for the pupa positive household index, the effect of the intervention was very similar in households with regular (OR0.5, 95%CI 0.3-0.8) and irregular (OR 0.5, 95%CI 0.3-0.9) water supply. While Aedes aegypti control efforts based on informed community mobilisation had a strong impact on households without a regular water

Those assessing the outcomes and analyzing the data were blinded to group assignment. Centralized computerized randomization after the baseline study allocated half the sites to intervention, stratified by country, evidence of recent dengue virus infection in children aged 3-9, and vector indices. Random sample of communities in Managua, capital of Nicaragua, and three coastal regions in Guerrero State in the south of Mexico. Residents in a random sample of census enumeration areas across both countries: 75 intervention and 75 control clusters (about 140 households each) were randomized and analyzed (60 clusters in Nicaragua and 90 in Mexico), including 85,182 residents in 18,838 households. A community mobilization protocol began with community discussion of baseline results. Each intervention cluster adapted the basic intervention-chemical-free prevention of mosquito reproduction-to its own circumstances. All clusters continued the government run dengue control program. Primary outcomes per protocol were self reported cases of dengue, serological evidence of recent dengue virus infection, and conventional entomological indices (house index: households with larvae or pupae/households examined; container index: containers with larvae or pupae/containers examined; Breteau index: containers with larvae or pupae/households examined; and pupae per person: pupae found/number of residents). Per protocol secondary analysis examined the effect of Camino Verde in the context of temephos use. With cluster as the unit of analysis, serological evidence from intervention sites showed a lower risk of infection with dengue virus in children (relative risk reduction 29.5%, 95% confidence interval 3.8% to 55.3%), fewer reports of dengue illness (24.7%, 1.8% to 51.2%), fewer houses with larvae or pupae among houses visited

    2009-01-01

    Introduction Semantic variability is a barrier to effective networking of long-term care (LTC) services. The same name may be used for services providing different activities (i.e. day centres), and services with different names may have a similar pattern of care delivery. Furthermore, services are complex constructs which depend on local characteristics, vary over time and do not allow comparisons like with like. At present there is no standard coding system of LTC in Europe. This fact impedes cross-national comparisons, hampers European statistics on service availability, access and use, and slows down the development of international care planning strategies and patient mobility. Description The ‘Description and Evaluation of Services and Directories in Europe’ (DESDE) adapts to LTC the only currently available methodology for mapping, comparing and monitoring mental health and disability services (European Service Mapping Schedule—ESMS), which has already been applied in 16 countries in Europe. The system is based on descriptors called ‘Main Types of Care’ (MTC) including accessibility, information, self-help, outpatient and community care, day care and residential care. Services are arranged or organised in cluster combination of MTCs which emulate ‘bar codes’, identifying service characteristics according to MTCs. Thus, MTC availability and use can be compared across areas regardless of how services are named. Conclusion DESDE is a standard coding system of services for LTC which can be incorporated to electronic registers, databases and websites.

    2003-08-01

    A década de 70 do século passado foi marcada pelo estudo das concepções alternativas que os alunos trazem para a sala de aula. A identificação destas concepções foi o ponto de partida para promover a mudança conceitual, onde as pré-concepções seriam trocadas pelas concepções científicas. Na década seguinte, surgiram muitas propostas de estratégias educacionais para facilitar esta troca, na sua maioria baseadas na idéia do conflito cognitivo, proposta por Piaget. Entretanto, os resultados pouco animadores conduziram à percepção de que a mudança conceitual é um processo mais complexo. Pelas idéias da Ciência Cognitiva, a mudança conceitual é uma mudança progressiva dos modelos mentais que o aluno tem sobre o mundo físico, através de enriquecimento e revisão. A causa das Estações do Ano é um tópico sobre o qual a maioria dos estudantes apresenta concepções alternativas. Os autores fizeram um levantamento sobre as pré-concepções encontradas em trabalhos sobre o tema (16 referências), procurando encontrar elementos comuns que indicassem a presença de modelos mentais específicos. As pré-concepções encontradas na literatura foram obtidas usando-se diversas metodologias (desde entrevistas clínicas até questionários de múltipla escolha) e envolvendo alunos e professores de diferentes regiões geográficas. A partir de uma análise aprofundada de cada trabalho, e utilizando-se a técnica das Redes Sistêmicas, chegou-se a conclusão que as diversas pré-concepções identificadas (em torno de 50), poderiam ser representadas por 6 modelos mentais, onde a explicação da causa das estações do ano tem um mecanismo causal responsável. Os mecanismos causais identificados foram: a dependência da distância, a dependência da orientação, a dependência conjunta da distância e orientação, a dependência da obstrução, a dependência da velocidade e a dependência da inclinação dos raios solares.

    Los modelos de Heggie y Ramamani de satélites galácticos en órbitas circulares se basan en una teoría aproximada, por lo que es importante verificar su estabilidad mediante simulaciones numéricas. En esta forma, hemos logrado mostrar que son estables sobre intervalos de tiempo mucho mayores que los que lograron los propios autores de los modelos. Por otra parte, dado que hemos mostrado que el caos es significativo en estos modelos, son un sistema ideal para investigar si, pese a ello, se mantienen estacionarios. Nuestras simulaciones numéricas muestran que, pese al caos, la estacionariedad se mantiene sobre intervalos de centenares de tiempos de cruce del sistema, mucho mayores que los tiempos de Liapunov característicos de sus movimientos caóticos.

    In contrast to climacteric fruits, in which ethylene is known to be pivotal, the regulation of ripening in non-climacteric fruits is not well understood. The strawberry is a typical example of a non-climacteric fruit, which has been used as a model system of these types of fruit. In this study, the effect of exogenous ethephon on the expression of ethylene biosynthesis and signaling genes, FaERF2 and FaACO1, was analyzed in the Fragaria ananassa cultivar Camino Real by quantitative real-time polymerase chain reaction, and the physicochemical and phytochemical characteristics of fruits were evaluated in field trials and postharvest tests. Transcript accumulation was influenced by exogenous treatment with ethephon, which affected the pattern of gene expression during different stages of growth and fruit development, with the highest expression occurring during postharvest tests. In addition, ethephon significantly influenced the phytochemical profile of sugars, anthocyanins, phenolic compounds, and vitamin C contents both in the field- and postharvest-treated fruits at different stages. These results indicate that ethylene regulates the phenylpropanoid maturation pathway in strawberry fruit.

    Since the Aedes aegypti mosquitoes that transmit dengue virus can breed in clean water, WHO-endorsed vector control strategies place sachets of organophosphate pesticide, temephos (Abate), in household water storage containers. These and other pesticide-dependent approaches have failed to curb the spread of dengue and multiple dengue virus serotypes continue to spread throughout tropical and subtropical regions worldwide. A feasibility study in Managua, Nicaragua, generated instruments, intervention protocols, training schedules and impact assessment tools for a cluster randomised controlled trial of community-based approaches to vector control comprising an alternative strategy for dengue prevention and control in Nicaragua and Mexico. The Camino Verde (Green Way) is a pragmatic parallel group trial of pesticide-free dengue vector control, adding effectiveness to the standard government dengue control. A random sample from the most recent census in three coastal regions of Guerrero state in Mexico will generate 90 study clusters and the equivalent sampling frame in Managua, Nicaragua will generate 60 clusters, making a total of 150 clusters each of 137-140 households. After a baseline study, computer-driven randomisation will allocate to intervention one half of the sites, stratified by country, evidence of recent dengue virus infection in children aged 3-9 years and, in Nicaragua, level of community organisation. Following a common evidence-based education protocol, each cluster will develop and implement its own collective interventions including house-to-house visits, school-based programmes and inter-community visits. After 18 months, a follow-up study will compare dengue history, serological evidence of recent dengue virus infection (via measurement of anti-dengue virus antibodies in saliva samples) and entomological indices between intervention and control sites. Our hypothesis is that informed community mobilisation adds effectiveness in controlling

    La astronomía gamma, en el extremo de energías detectadas hasta el presente, se encuentra en desarrollo en muchas partes del mundo y proporciona resultados sorprendentes a medida que la tecnología avanza en el desarrollo de nuevos detectores. La técnica Cherenkov Atmosférica es la utilizada para la detección, mediante telescopios en tierra, del efecto secundario causado por la radiación gamma de muy altas energías (E ≈ TeV). Por medio de telescopios o arreglos de detectores y utilizando la técnica mencionada, se han podido detectar algunas fuentes puntuales de mucha importancia astrofísica como la Nebulosa del Cangrejo y la galaxia de núcleo activo Markarian 421. El sistema instalado en San Juan, en cooperación con el grupo de Radiación Gamma del Observatorio Whipple, está constituído por tres colectores de 1.5m que registran pulsos de luz generados por las cascadas de partículas producidas por rayos cósmicos de todo tipo al entrar en la atmósfera terrestre. El sistema opera por barrido en ascención recta de la fuente observada que, para esta etapa del experimento, es el Centro Galáctico. Esta fuente extensa es conocida como emisor gamma de energías inferiores al TeV y ha sido observada anteriormente en este rango de energía desde el hemisferio norte pero con elevaciones bajas, situación no óptima para este tipo de técnica. Se presentan los primeros resultados del análisis de los datos obtenidos observando la región del Centro Galáctico, luego de dos años de observaciones, así como una descripción de la técnica Cherenkov Atmosférica y del equipo utilizado en la experiencia.

Concrete tanks and barrels accounted for the majority of pupal productivity. Covering water containers could be an effective means of Ae. aegypti vector control, with a bigger effect than using temephos.

    O presente trabalho propõe-se a resgatar uma experiência que teve lugar no Planetário de São Paulo nos anos 60. Em 1962, o Sr. Acácio, então com 37 anos, deficiente visual desde os 27, passou a assistir às aulas ministradas pelo Prof. Aristóteles Orsini aos integrantes do corpo de servidores do Planetário. O Sr. Acácio era o único deficiente da turma e, embora possuísse conhecimentos básicos e relativamente avançados de matemática, enfrentava dificuldades na compreensão e acompanhamento da exposição, como também em estudos posteriores. Com o intuito de auxiliá-lo na superação desses problemas, o Prof. Orsini solicitou a construção de modelos mecânicos que, através do sentido do tato, permitissem o acompanhamento das aulas e a transposição do modelo para o "constructo" mental. Essa prática mostrou-se tão eficaz que facilitou sobejamente o aprendizado da matéria pelo sujeito. O Sr. Acácio passou a integrar o corpo de professores do Planetário/Escola Municipal de Astrofísica, tendo ficado responsável pelo curso de "Introdução à Astronomia" por vários anos. Além disso, a experiência foi tão bem sucedida que alguns dos modelos tiveram seus elementos constitutivos pintados diferencialmente para serem utilizados em cursos regulares do Planetário, tornando-se parte integrante do conjunto de recursos didáticos da instituição. É pensando nessa eficácia, tanto em seu objetivo original permitir o aprendizado de um deficiente visual quanto no subsidiário recurso didático sistemático da instituição que decidimos resgatar essa experiência. Estribados nela, acreditamos ser extremamente produtivo, em termos educacionais, o aperfeiçoamento dos modelos originais, agora resgatados e restaurados, e a criação de outros que pudessem ser utilizados no ensino dessa ciência a deficientes visuais.

    Investigadores como Merritt, Valluri, Pfenniger o Contopoulos (por citar los más relevantes) consideran seriamente la hipótesis que la difusión de Arnold juega un rol importante en la evolución dinámica de los sistemas estelares y planetarios. Sin embargo no existe ninguna evidencia. El mayor problema para investigar fenómenos como éste es que uno debe estudiar numéricamente sistemas multidimensionales (más de dos grados de libertad) y visualizar de alguna manera el espacio de fases (más de cuatro dimensiones). Más complicado aún es el caso de difusión de Arnold, donde deben considerarse tiempos de movimiento extremadamente largos y tratar con parámetros exponencialmente pequeños. El propósito de este trabajo es estudiar, en un modelo simple 3D, la existencia o no de difusión de Arnold mediante experimentos numéricos y estimaciones analíticas. Siguiendo los trabajos de Cincotta (2000) y Cincotta, Nuñez y Simo (2000), aquí se pretende ``visualizar" la difusión y, a la vez, determinar la escala de tiempo en la que ésta se podría manifestar. Este trabajo es el escalón inicial para luego abordar este problema en modelos.

    In connection with the Bureau of Land Management’s (BLM’s) Solar Programmatic Environmental Impact Statement (Solar PEIS), Argonne National Laboratory (Argonne) has conducted an extended visual impact analysis for selected key observation points (KOPs) within three National Park Service (NPS) units located within the 25-mi (40-km) viewshed of four solar energy zones (SEZs) identified in the Solar PEIS. The analysis includes only those NPS units that the Solar PEIS identified as potentially subject to moderate or strong visual contrasts associated with solar development within the SEZs. The NPS units included in the analysis are Death Valley and Joshua Tree National Parks and El Camino Real De Tierra Adentro National Historic Trail. The analysis showed that certain KOPs in each of these NPS units could potentially be subject to major visual contrast and impacts from solar development within the SEZs, but many of the KOPs would likely be subject to moderate, minor, or negligible contrasts and impacts, generally because they were relatively distant from the relevant SEZ, had views of the SEZ partially blocked by intervening terrain, and/or had very low vertical angles of view toward the SEZ. For all three NPS units, power tower facilities were found to be major contributors to potential visual contrasts, primarily because of the long-distance visibility of intensely bright reflection of light from the receivers on the central towers, but also because of the height and strong vertical line of the tower structures and the potential for night-sky impacts from FAA-mandated hazard navigation lighting.

  6. Discos de acreción circumplanares: Modelo de Co-acreción

    NASA Astrophysics Data System (ADS)

    Parisi, M. G.; de Elía, G.

    Los discos de acreción circumplanetarios precursores de los satélites regulares de los planetas gigantes, se pueden formar por cuatro mecanismos (Pollack y otros, 1991, In Uranus, Bergtralh, Miner y Mattews, Eds., p. 469, Univ. de Arizona Press, Tucson). En este trabajo estudiamos uno de tales mecanismos: el Modelo de Co-acreción. En dicho modelo, el disco circumplanetario se forma a partir de las colisiones mutuas entre planetesimales dentro de la esfera de Hill del planeta durante el proceso de formación planetaria. Realizamos un modelo semi-analítico para calcular la masa del disco y compararla con la masa requerida para formar los satélites regulares de los planetas gigantes. Hemos obtenido una cota superior para la masa del disco que resulta inferior a la masa de los satélites más grandes de los planetas gigantes. En principio, estos resultados permitirían descartar el modelo de co-acreción como uno de los procesos que podrían dar lugar a la formación de los satélites regulares. Estos resultados permiten obtener restricciones en el escenario de formación planetaria y en los mecanismos de formación de sistemas de satélites.

    Pigozzi, Mary Joy

    2010-06-01

    This paper looks at the implementation of the DESD from a global perspective. It takes the position that quality education is fundamental for learning how to live sustainably, and that the DESD needs to be better positioned in the education landscape and conceived as a global social movement that must be fostered and nurtured for the well-being of humankind. It suggests that, while there has been progress, much remains to be achieved. Several key challenges are identified. With regard to overcoming these obstacles, it focuses on macro-level strategies that would allow the development of environments in which actions can take root and grow so that the work of the DESD endures beyond the decade itself. Finally, it suggests that there are some opportunities that can be seized to make the task ahead easier to accomplish.

    Urine sampling of the free amino acid pool serves to reflect plasma enrichment and is used as a noninvasive means to determine isotope enrichment in studies of amino acid metabolism. We determined the effect of D-[13C]phenylalanine and D-[13C]lysine content of tracers on urinary amino acid enrichment following oral infusion of L-[13C]phenylalanine in 18 preterm infants and L-[1-(13)C]lysine in seven healthy adult females. Urinary [13C]phenylalanine enrichment was higher (P < .0001) for L-[13C]phenylalanine containing 0.4% D-[13C]phenylalanine (28.6 +/- 7.1) versus L-[1-(13)C]phenylalanine that contained undetectable D-[13C]phenylalanine (10.2 +/- 1.5). D-[13C]phenylalanine, measured by chiral column gas chromatography-mass spectrometry (GC-MS), accounted for 10% to 30% (20.5% +/- 7%) of total phenylalanine in the urine of infants who received 0.4% D-[13C]phenylalanine, and was absent from the urine of infants receiving tracer with undetectable [13C]phenylalanine. Urinary L-[13C]phenylalanine enrichment did not differ between tracer groups (9.8 +/- 1.5 and 9.8 +/- 2.5). In adult females, the use of L-[1-(13)C]lysine (1.6% D-lysine) resulted in a higher (P < .02) urine total L,D-[13C]lysine enrichment compared with plasma enrichment (40.8 +/- 4.1 v 11.1 +/- 0.7). This study demonstrates the significant presence of D-[13C]amino acids in urine that originate as contaminants from commercially manufactured tracers, as a result of renal tubular discrimination of D-amino acids. A tracer containing detectable amounts of D-[13C]isomer cannot be recommended for any study in which urine will be used to reflect enrichment in the arterial plasma pool.

  14. Un modelo general de eyección de materia estelar

    NASA Astrophysics Data System (ADS)

    Rotstein, N. O.

    Posiblemente, la más directa y dramática evidencia de la pérdida de masa por parte de diferentes objetos astrofísicos la constituye el fenómeno de eyección persistente de materia. En el caso particular de las estrellas, las características y los mecanismos que impulsan a sus atmósferas externas hacia el medio interestelar varían a lo largo del diagrama evolutivo. En parte por este motivo, en parte por las dificultades matemáticas involucradas, es muy difícil elaborar un modelo que pueda dar cuenta de los diferentes mecanismos que originan e impulsan el viento estelar. Cabe entonces preguntarse si es posible desarrollar un único modelo en el que estos mecanismos puedan ser considerados (y variados) como parámetros externos que responden a las características de cada región de la secuencia evolutiva. La respuesta es que, en función de la geometría del campo electromagnético involucrado, todo depende de la simetría del problema. En este trabajo se presenta el análisis detallado de una de tales simetrías, discutiendo en particular los resultados obtenidos a la luz de las observaciones disponibles.

    This work is an extened summary of the autor's PhD thesis. It deals with the teaching of astronomy (day/night, seasons) in primary school. At first, students teachers' undestanding of astronomical concepts related to Sun-Earth system have been analysed. Taking into account the results of the previous analysis and using a socio-constructivist approach a teaching sequence has been designed. This sequence has been tested with different groups of students teachers showing an improvement in their undestanding of elementary astronomical concepts. El trabajo que presentamos es un resumen extenso de la tesis doctoral del autor. El enfoque utilizado ha sido tratar de ligar la investigación sobre las ideas, razonamientos y obstáculos de los profesores de primaria con la planificación de la enseñanza del modelo Sol-Tierra que permite explicar el ciclo día/noche y las estaciones. En primer lugar, se ha procedido a realizar un análisis crítico de los resultados que se obtienen en el aprendizaje de los contenidos astronómicos en la enseñanza habitual. En segundo lugar se ha diseñado un curriculum potencialmente superador de esta situación desde una orientación que concibe la enseñanza y el aprendizaje como un proceso de construcción de conocimientos en una estructura problematizada. Finalmente, esta secuencia didáctica ha sido experimentada con diferentes grupos de estudiantes de magisterio, mostrando una mejora relevante en la comprensión de los conceptos astronómicos fundamentales.

    The Modelo Formation of the central and eastern Santa Monica Mountains is an Upper Miocene siliceous-diatomaceous shale and sandstone submarine-fan sequence, which was deposited in the northern Los Angeles basin. The graded, poorly sorted, and angular sandstones comprise channelized mid-fan facies deposited at middle-to-upper-bathyal depths; they are arkosic (58% feldspar) with variable amounts of matrix. Published paleocurrent data yield a south-southwest flow direction. The direction of the paleocurrents constrains the timing of deposition to be after rotation of the Transverse Ranges (after 15 Ma.) Biostratigraphic data indicate that deposition commenced during the Late Mohnian (after 10.8 Ma). QFL plots indicate that the provenance was basement uplift to transitional arc (e.g. Dickinson, 1985). The meta-igneous lithic fragments and the high feldspar content of the rocks suggest an anorthositic, gneissic, tonalitic, or mylonitic source terrane. Sandstone modes and conglomerate clasts indicate that the basal section was derived locally from the Santa Monica Slate. The upper section represents a volcanic unroofing sequence, as evidenced by decreasing volcanic lithic fragments upsection. Crowell (1982) suggested 60 km of right slip on the San Gabriel fault between 12 and 5 Ma. Palinspastic restoration places the Santa Monica Mountains immediately south of the San Gabriel Mountains, which wee the likely source for Modelo sandstones. Based on plagioclase composition (95% oligoclase and albite) of Modelo sandstone, the anorthosite body in the western San Gabriel Mountains is an unlikely source. However, a source in the mylonitic, gneissic, and tonalitic bodies of the eastern San Gabriel Mountains could explain the observed petrography. This source for the Modelo is consistent with 60 km of movement on the San Gabriel fault.

  19. Evaluation of an integrated system for classification, assessment and comparison of services for long-term care in Europe: the eDESDE-LTC study

    PubMed Central

    2013-01-01

    Background The harmonization of European health systems brings with it a need for tools to allow the standardized collection of information about medical care. A common coding system and standards for the description of services are needed to allow local data to be incorporated into evidence-informed policy, and to permit equity and mobility to be assessed. The aim of this project has been to design such a classification and a related tool for the coding of services for Long Term Care (DESDE-LTC), based on the European Service Mapping Schedule (ESMS). Methods The development of DESDE-LTC followed an iterative process using nominal groups in 6 European countries. 54 researchers and stakeholders in health and social services contributed to this process. In order to classify services, we use the minimal organization unit or “Basic Stable Input of Care” (BSIC), coded by its principal function or “Main Type of Care” (MTC). The evaluation of the tool included an analysis of feasibility, consistency, ontology, inter-rater reliability, Boolean Factor Analysis, and a preliminary impact analysis (screening, scoping and appraisal). Results DESDE-LTC includes an alpha-numerical coding system, a glossary and an assessment instrument for mapping and counting LTC. It shows high feasibility, consistency, inter-rater reliability and face, content and construct validity. DESDE-LTC is ontologically consistent. It is regarded by experts as useful and relevant for evidence-informed decision making. Conclusion DESDE-LTC contributes to establishing a common terminology, taxonomy and coding of LTC services in a European context, and a standard procedure for data collection and international comparison.

Se evaluaron los resultados en cuanto al logro del aprendizaje significativo. La pregunta central de la investigación fue: ¿Cómo aporta el modelo educativo en la didáctica y comprensión del tema de fotosíntesis? Se efectuó una investigación acción con una fase cuantitativa y una cualitativa. Para la fase cuantitativa se elaboró una prueba para determinar las concepciones alternativas, se validó y se sometió a los estudiantes que participaron en el estudio antes y después de ofrecer la unidad de metabolismo celular. Los participantes eran estudiantes de primer año de la Universidad de Puerto Rico en Bayamón (UPRB). Se llevó a cabo un análisis de consistencia interna de la prueba mediante el método Alfa de Cronbach. Se analizaron las contestaciones a cada pregunta mediante la prueba de Ji cuadrado de contingencia, se efectuó la prueba de t y el coeficiente r de Pearson. La fase cualitativa incluyó la observación participativa de la investigadora- profesora, las reflexiones de los estudiantes y la información de las entrevistas semi-estructuradas que se realizaron a tres estudiantes del curso. El análisis se llevó a cabo mediante el Modelo de Wolcott. Se trabajaron diez CA de las cuales siete fueron corregidas mediante el Modelo MODEF. Las actividades más importantes para el proceso de aprendizaje incluyeron el trabajo de investigación o búsqueda de información para hacer una presentación digital, la elaboración de tablas, los mapas de conceptos, el uso de visuales o videos y las analogías para explicar conceptos o procesos. En conclusión: se recomienda el uso del Modelo MODEF para la discusión del tema de

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

  3. El origen de las galaxias en modelos jerárquicos de formación de la estructura

    NASA Astrophysics Data System (ADS)

    Navarro, J. F.

    En esta charla presentaré una revisión de los modelos corrientes de formación de galaxias. En particular, haré énfasis en el origen de la gran variedad de morfologías galácticas y de las correlaciones entre las propiedades estructurales de discos y esferoides, todo dentro del contexto cosmológico jerárquico provisto por teorías como la de materia oscura fría. En este tipo de teorías las correlaciones observadas entre la luminosidad, velocidad de rotación, momento angular, y tamaño de galaxias son el resultado de la falta de escalas naturales en el proceso de formación de los halos de materia oscura que dichas galaxias habitan. Simulaciones numéricas que incorporan efectos gravitacionales, hidrodinámicos y de formación estelar ilustran estas ideas y demuestran las dificultades que aquejan a modelos donde tanto discos como esferoides son el resultado final de una secuencia de fusiones de sistemas protogalácticos.

    2003-08-01

    O estudo das variações do raio solar durante o ciclo de atividades do Sol e das diferenças em relação à sua distribuição angular nos fornece informações importantes sobre as mudanças na estrutura da atmosfera solar. Neste trabalho foram analisados mais de 3600 mapas do Sol em 17 GHz obtidos pelo Rádio Heliógrafo de Nobeyama (NoRH), durante 1 ciclo de atividade solar (1992-2003). O raio solar foi definido no ponto onde a temperatura de brilho do mapa era equivalente à metade da temperatura do Sol calmo (temperatura mais comum no mapa).Em relação à sua variação ao longo do ciclo solar, o estudo foi dividido em duas partes: a) ajuste de uma circunferência a pontos distribuídos ao redor do Sol todo. Este estudo mostrou uma variação correlacionada com o ciclo de atividade do Sol. b) ajuste da circunferência a pontos situados somente nas regiões polares. Neste caso os resultados mostraram que o raio polar sofre pouca variação durante o ciclo, com tendência à anticorrelação com este. Além disto, a média do raio polar, durante o período analisado, foi 1" menor que o raio medido no Sol todo. Para estudar a distribuição angular do raio solar, comparamos a média da distribuição de 10 mapas no período de mínima atividade solar com a média de 10 mapas no período de máximo, este estudo mostrou um grande aumento do raio na região equatorial no período de máxima atividade solar. As medidas do raio foram usadas como um dos parâmetros para a criação de um modelo atmosférico (além da temperatura de brilho do Sol e do abrilhantamento do limbo observado), onde mostramos que um modelo atmosférico com a região de transição situada a 3500 km fornece um raio 5" menor que as medidas observacionais. Esta incompatibilidade do modelo com os dados observacionais foi contornada com a inclusão de espículas, estas fazem com que o raio solar aumente proporcionalmente à altura que estas atingem na atmosfera solar.

  5. órbitas regulares y caóticas en modelos autoconsistentes de satélites galácticos

    NASA Astrophysics Data System (ADS)

    Muzzio, J. C.; Carpintero, D. D.; Wachlin, F. C.

    En un trabajo anterior mostramos que el caos podía ser significativo en satélites galácticos. Ahora hemos clasificado órbitas en modelos de Heggie-Ramamani que tienen la ventaja de ser autoconsistentes y de que se conoce su función de distribución. Hemos podido así determinar porcentajes de órbitas caóticas, que resultan ser de entre 25% y 65%, según el modelo considerado. La dependencia de la caoticidad con la energía orbital es complicada y sugiere que el origen de la caoticidad se halla en la acción combinada de la fuerza de atracción del propio satélite con la fuerza de Coriolis y la fuerza centrifuga.

En esta comunicación presentamos una solución de las ecuaciones MHD en el entorno del origen, construyendo series bidimensionales para todas las magnitudes físicas involucradas. Valiéndonos de la alta simetría y de las características del problema, logramos reducir el número de coeficientes a calcular. Utilizamos un programa autoconsistente para extender el cálculo a regiones vecinas con difusión moderada o despreciable.

    The exact mechanism of helicase-mediated salinity tolerance is not yet understood. We have isolated a DESD-box containing cDNA from Pisum sativum (Pea) and named it as PDH45. It is a unique member of DEAD-box helicase family; containing DESD instead of DEAD/H. PDH45 overexpression driven by constitutive cauliflower mosaic virus-35S promoter in rice transgenic [Oryza sativa L. cv. Pusa Basmati 1 (PB1)] plants confers salinity tolerance by improving the photosynthesis and antioxidant machinery. The Na(+) ion concentration and oxidative stress parameters in leaves of the NaCl (0, 100 or 200 mM) treated PDH45 overexpressing T1 transgenic lines were lower as compared to wild type (WT) rice plants under similar conditions. The 200 mM NaCl significantly reduced the leaf area, plant dry mass, net photosynthetic rate (PN), stomatal conductance (gs), intercellular CO2 (Ci), chlorophyll (Chl) content in WT plants as compared to the transgenics. The T1 transgenics exhibited higher glutathione (GSH) and ascorbate (AsA) contents under salinity stress. The activities of antioxidant enzymes viz. superoxide dismutase (SOD), ascorbate peroxidase (APX), guaiacol peroxidase (GPX) and glutathione reductase (GR) were significantly higher in transgenics; suggesting the existence of an efficient antioxidant defence system to cope with salinity induced-oxidative damage. Yeast two-hybrid assay indicated that the PDH45 protein interacts with Cu/Zn SOD, adenosine-5'-phosphosulfate-kinase, cysteine proteinase and eIF(4G), thus confirming the involvement of ROS scavenging machinery in the transgenic plants to provide salt tolerance. Furthermore, the T2 transgenics were also able to grow, flower, and set viable seeds under continuous salinity stress of 200 mM NaCl. This study provides insights into the mechanism of PDH45 mediated salinity stress tolerance by controlling the generation of stress induced reactive oxygen species (ROS) and also by protecting the photosynthetic machinery through a

  9. Estudio de la formación de galaxias espirales en un modelo de agregación jerárquica

    NASA Astrophysics Data System (ADS)

    Tissera, P.; Saiz, A.; Dominguez-Tenreiro, R.

    El estudio de formación de galaxias espirales ha llevado al desarrollo de numerosos modelos teóricos (e.g. White & Rees 1978). En la actualidad, el modelo más aceptado predice la formación de una galaxia espiral a partir del colapso disipativo del gas en el pozo de potencial de un halo oscuro, conservando su momento angular específco (Fall & Efstathiou 1980). En los últimos años, ha sido posible realizar simulaciones numéricas hidrodinámicas, las cuales describen la evolución conjunta de la materia oscura y los bariones. Estos experimentos han señalado la dificultad de formar estructuras discoidales con propiedades consistentes con las observaciones, en modelos de agregación jerárquica. El problema principal se origina en la pérdida catastrófica de momento angular de la componente disipativa, durante el proceso de ensamblaje de los objetos, a través de la fusión de subestructura (Navarro & Steinmetz 1997). Estos experimentos no incluían procesos de formación estelar. En este trabajo, se expondrán resultados de simulaciones hidrodinámicas cosmológicas, incluyendo formación estelar (Tissera et al 1997), donde ha sido posible reproducir objetos discoidales con contrapartida observacional. El elemento fundamental ha sido la formación de bulbos estelares, los cuales han evitado la pérdida catastrófica de momento angular de los bariones. Se encontró que los discos exponenciales puramente gaseosos son altamente inestables y suceptibles de generar barras, responsables de la pérdida de momento angular y la caída violenta del gas hacia la región central. Estas inestabilidades son fácilmente inducidas durante interacciones y fusiones con objetos vecinos (Barnes & Hernquist 1996). Un bulbo estelar (o un objeto masivo y compacto) estabiliza el disco ante perturbaciones externas, asegurándole un potencial simétrico (Sellwood & Moore 1998, Van der Bosch 1998). En este caso, el gas en el disco no pierde completamente su momento angular intr

Sin embargo, los únicos modelos autoconsistentes de los que se disponía para ellos eran los de Heggie-Ramamani, cuya función de distribución depende sólo de la energía por lo que no mostraban diferencias entre las distribuciones de sus órbitas regulares y caóticas. Ahora, mediante una aproximación cuadrupolar, hemos logrado construir modelos autoconsistentes de satélites galácticos con distribuciones de velocidades anisotrópicas (lo que indica que sus funciones de distribución no dependen sólo de la energía) y hemos logrado revelar las diferencias entre las estructuras espaciales de las órbitas de distinta caoticidad.

  11. Estructura espacial de las órbitas caóticas en un modelo autoconsistente de galaxia elíptica

    NASA Astrophysics Data System (ADS)

    Muzzio, J. C.

    Hemos logrado construir modelos autoconsistentes de sistemas estelares utilizando una aproximación cuadrupolar para el potencial. Esto nos permite determinar órbitas y exponentes de Lyapunov de objetos que tienen posiciones y velocidades equivalentes a las que se obtienen de la funcón de distribución del sistema. La distribución espacial de las órbitas caóticas exhibe considerable estructura y, lo que es más importante aún, los valores de los exponentes de Lyapunov calculados sobre intervalos finitos de tiempo, muestran una fuerte correlación con el comportamiento de la órbita en esos mismos intervalos, por lo que permiten reconocer distintos subsistemas con diferentes distribuciones espaciales.

  12. Comparação de modelos para o cálculo de perturbações orbitais devidas à maré terrestre

    NASA Astrophysics Data System (ADS)

    Vieira Pinto, J.; Vilhena de Moraes, R.

    2003-08-01

    Aplicações recentes de satélites artificiais com finalidades geodinâmicas requerem órbitas determinadas com bastante precisão. Em particular marés terrestres influenciam o potencial terrestre causando perturbações adicionais no movimento de satélites artificiais, as quais tem sido medidas por diversos processos. A atração exercida pela lua e pelo sol sobre a terra produz deslocamentos elásticos em seu interior e uma protuberância em sua superfície. O resultado é uma pequena variação na distribuição da massa na terra, consequentemente no geopotencial. As perturbações nos elementos orbitais de satélites artificiais terrestres devidas a maré terrestre podem ser estudadas a partir das equações de Lagrange, considerando-se um conveniente potencial. Por outro lado, como tem sido feito pelo IERS, as mudanças induzidas pela maré terrestre no geopotencial podem ser convenientemente modeladas como variações nos coeficientes Cnm e Snm do geopotencial. As duas teorias ainda não foram comparados para um mesmo satélite. Neste trabalho são apresentadas e comparadas as variações de longo período e seculares nas perturbações orbitais devidas à maré terrestre, calculadas por um modelo simples, o de Kozai, e pelo modelo do IERS. Resultados preliminares mostram, para os satélites SCD2 e CBERS1, e para a Lua em movimento elíptico e precessionando, as perturbações seculares no argumento do perigeu e na longitude do nodo ascendente.

  13. El rol de Ia colaboracion y el Modelo de Aprendizaje Basado en Proyectos (ABPr) mediante el lente de la Teoria de Actividad (CHAT): un estudio de caso con estudiantes de 9no grado

    NASA Astrophysics Data System (ADS)

    Delgado, Isabel C.

    Los modelos de eensenanza y aprendizaje constructivistas conceptualizan el aprendizaje como un proceso activo. El modelo de Aprendizaje Basado en Proyectos (ABPr) se distingue por una serie de componentes, entre los cuales se destaca el aspecto colaborativo y cooperativo como un reto al momento de su implantacion. Son pocas las investigaciones que se concentran en este aspecto del modelo. En este estudio, se analizaron las diversas interacciones que surgen durante la implantacion de una unidad curricular sobre el tema de Geologia de Puerto Rico, la cual se diseno con el modelo ABPr cuyo enfoque es orientacion a proyectos. Particularmente, se examinaron las interacciones sociales que surgen entre los pares y entre pares y docente durante el proceso de planificacion y desarrollo de los productos finales, al igual que las interacciones entre los estudiantes y el material didactico en estas etapas del modelo. La investigacion es de tipo cualitativo e incorpora como diseno el estudio de caso. Las diversas interacciones constituyen la unidad de analisis. En el estudio participaron 19 estudiantes de 9no grado, a quienes se organizaron en 5 grupos colaborativos por temas de interes (Pangea, Placas tectonicas, Volcanes, Tsunamis y Terremotos). Las tecnicas que se utilizaron para recopilar los datos fueron: observaciones participativas, grupos focales y analisis de documentos (cuadernos reflexivos y respuestas de los estudiantes a la pregunta central del proyecto). Para el analisis de los datos se aplico la teoria de actividad (CHAT) que concentra la unidad de analisis en la actividad humana en un contexto particular. Los resultados del estudio senalan que las interacciones entre pares, entre pares y docente, asi como entre estudiantes y material didactico son fundamentales en el proceso de aprendizaje. Una mayor interaccion entre pares durante las etapas de planificar y desarrollar los productos finales de la unidad, promueve una mejor comprension de los conceptos de la

    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.

    2012-07-01

    There are several interesting astronomical topics that must be addressed in the High School and Elementary/Middle School in the disciplines of Geography and of Sciences. Among them, the topic of time zones which is one of the most important to understand the correlation of the Earth's rotation and its implications on daily activities of citizens in local scale, regional and global scales which involve problems of time differences. For the teaching of time zones in the lessons of Geography, for example, there are bi-dimensional representations of thematic maps of world time zones, textbooks and atlas. It happens that teachers face some difficulties to permit its students to view three-dimensionally this astronomical phenomenon from the textbooks available in schools. The aim of this paper is to present two proposals with low-cost materials, which allow the preparation of three-dimensional models for the teaching of time zones. Há vários temas astronômicos interessantes que devem ser trabalhados nos Ensinos Médio e Fundamental, nas disciplinas de Geografia e de Ciências. Entre eles, o tema dos fusos horários que é um dos mais importantes para se correlacionar a rotação da Terra e suas implicações nas atividades cotidianas dos cidadãos em escala local, regional e global, que envolvem problemas de diferenças horárias. Para o ensino dos fusos horários nas aulas de Geografia, por exemplo, há representações bidimensionais de mapas temáticos de fusos horários mundiais, nos livros didáticos e nos atlas. Ocorre que os professores enfrentam algumas dificuldades para possibilitar aos seus alunos a visão tridimensional deste fenômeno astronômico, a partir dos materiais didáticos disponíveis nas escolas. O objetivo deste trabalho é apresentar duas propostas para a confecção de materiais de baixo custo, que possibilitem a elaboração de modelos tridimensionais para o ensino dos fusos horários.

    1998-08-01

    531 imagens contidas no The International Halley Watch Atlas of Large-Scale Phenomena (Brandt et al., 1992) cobrindo o período de setembro de 1985 a julho de 1986 foram analisadas visando identificar, caracterizar as propriedades e correlacionar estruturas morfológicas da cauda de plasma do cometa P/Halley. A análise revelou 47 eventos de desconexão (DEs) (Niedner & Brandt, 1979; Jockers, 1985; Celnik et al., 1988; Delva et al., 1991). A análise completa de todas as imagens encontra-se publicada em Voelzke & Matsuura, 1998. A distribuição dos DEs na distância heliocêntrica apresenta um caráter bimodal possivelmente associado com a distribuição espacial das fronteiras de setor magnético do meio interplanetário. Os 47 DEs fotografados em 47 imagens distintas permitiram determinar 19 origens de DEs, ou seja, o instante em que supostamente o cometa cruzou a fronteira entre setores magnéticos do vento solar. Tais dados cometários foram comparados com dados do vento solar provenientes de medidas realizadas in situ pelas sondas IMP-8, ICE e PVO, que mediram a variação da velocidade do vento solar, da densidade e da pressão dinâmica durante o intervalo analisado. Os dados destas sondas espaciais em conjunto com os da sonda Vega 1 foram usados para determinar o tempo das passagens do lençol de corrente. Com base nos dados das sondas foram calculadas as coordenadas heliográficas retroativas do lençol de corrente na "superfície fonte" dos mapas sinóticos do campo magnético de Hoeksema, 1989. O cálculo retroativo é feito através de um modelo simples de expressão do vento solar com velocidade uniforme, sendo considerada a co-rotação da magnetosfera com o Sol. Este trabalho apresenta os resultados desta comparação e a análise cinemática da origem dos DEs, determinada sob a hipótese que o plasma desconectado de um dado DE afasta-se com velocidade constante do núcleo cometário (Voelzke & Matsuura, 1998) e compara esta análise com outras que

    Drug-eluting stents have been effective in randomized controlled trials, but their safety and efficacy in patients with insulin-dependent diabetes has not been well studied. Baseline clinical and angiographic characteristics and in-hospital and follow-up events were recorded for enrolled patients. From October 2005 and October 2006, 581 patients with insulin-dependent diabetes and 1,078 with non-insulin-dependent diabetes treated with sirolimus- and paclitaxel-eluting stents were enrolled at 98 sites. The composite of death, myocardial infarction, and stroke, defined as major adverse cardiac and cerebrovascular events, as well as target vessel revascularization was used as the primary end point. Multiple logistic regression analysis was used to adjust for confounding parameters. Baseline clinical characteristics were more severe in patients with insulin-dependent diabetes, whereas descriptive characteristics were not unique. At 1-year follow-up, the comparison between the 2 groups revealed significantly higher rates of overall death (7.4% vs 4.6%, p <0.05), target vessel revascularization (15.1% vs 10.4%, p <0.05), and overall stent thrombosis (6.5% vs 4.1%, p <0.05) for insulin-dependent patients, while rates of major adverse cardiac and cerebrovascular events were not significantly different (12.8% vs 9.9%, p = 0.09). These results persisted even after risk adjustment for heterogenous baseline characteristics of the 2 groups. In conclusion, the data generated from the German Drug-Eluting Stent (DES.DE) registry revealed that even with drug-eluting stents, the annual risk for death, target vessel revascularization, and thrombotic events remains higher in patients with insulin-dependent diabetes compared to those with non-insulin-dependent diabetes.

    Introducción: En los últimos años, el campo de los probióticos ha experimentado un gran auge. Sin embargo, de los miles de cepas aisladas cada año por su potencial probiótico en los laboratorios de todo el mundo, muy pocas pasan a una fase de desarrollo industrial y menos aún son las que consiguen una vida comercial. Objetivo: En este artículo, se revisan los principales aspectos que se deben tener en cuenta en el, habitualmente, largo y tortuoso camino que debe seguir una cepa desde su aislamiento inicial hasta su comercialización. Resultados y conclusiones: Cualquier microorganismo probiótico debe estar correctamente identificado a nivel de especie y cepa. La secuencia del genoma es la mejor identificación posible, además de proporcionar información muy valiosa sobre su seguridad, funcionalidad y propiedades de interés tecnológico. Los casos en los que se ha podido establecer una relación entre un probiótico y un efecto adverso son muy escasos y han afectado a personas con patologías subyacentes. Globalmente, aunque las distintas pruebas in vitro, ex vivo y en modelos animales proporcionan información útil durante el proceso de selección de cepas, los únicos datos que permiten evaluar la seguridad y eficacia de un probiótico de una forma directa son los que se obtienen en el curso de ensayos clínicos correctamente diseñados y dirigidos específicamente a la población diana. Por otra parte, las empresas que comercializan probióticos tienen la necesidad de obtener una biomasa muy elevada de forma económicamente rentable y de que la concentración de bacterias viables necesaria para ejercer el efecto beneficioso se mantenga hasta el final de la vida útil del producto. Finalmente, los aspectos comerciales son determinantes en la decisión de afrontar el desarrollo industrial y la puesta en el mercado de un probiótico.

    Observações de Supernovas do tipo Ia mostram que a expansão do Universo está acelerando. Segundo as equações de Einstein uma componente com pressão negativa (energia escura) é necessária para explicar a aceleração cósmica. Além da energia escura é usualmente admitido que no Universo há também uma matéria exótica com pressão zero, que é chamada de matéria escura. Essa componente possui um papel fundamental na formação de estruturas no Universo. Recentemente tem se explorado a possibilidade de que matéria e energia escura poderiam ser unificadas através de uma única componente, que tem sido denominada de quartessência. Um exemplo de fluido com essas características é o Gás de Chaplygin Generalizado, que possui uma equação de estado da forma p = -A/ra. Inicialmente consideramos o caso especial a = 1 (gás de Chaplygin) e vinculamos parâmetros do modelo utilizando observações em raios-X do satélite Chandra da fração de massa de gás em aglomerados de galáxias. Uma comparação dos vínculos obtidos com esse teste com outros testes, tais como supernovas e idade do Universo, mostra que esse teste é bastante restritivo. Exibiremos ainda resultados para o caso em que a curvatura é nula e o parâmetro a está compreendido no intervalo -1 < a 1.

  4. Sediment accumulation, stratigraphic order, and the extent of time-averaging in lagoonal sediments: a comparison of 210Pb and 14C/amino acid racemization chronologies

    NASA Astrophysics Data System (ADS)

    2015-03-01

    Carbon-14 calibrated amino acid racemization (14C/AAR) data and lead-210 (210Pb) data are used to examine sediment accumulation rates, stratigraphic order, and the extent of time-averaging in sediments collected from the One Tree Reef lagoon (southern Great Barrier Reef, Australia). The top meter of lagoonal sediment preserves a stratigraphically ordered deposit spanning the last 600 yrs. Despite different assumptions, the 210Pb and 14C/AAR chronologies are remarkably similar indicating consistency in sedimentary processes across sediment grain sizes spanning more than three orders of magnitude (0.1-10 mm). Estimates of long-term sediment accumulation rates range from 2.2 to 1.2 mm yr-1. Molluscan time-averaging in the taphonomically active zone is 19 yrs, whereas below the depth of final burial (~15 cm), it is ~110 yrs/5 cm layer. While not a high-resolution paleontological record, this reef lagoon sediment is suitable for paleoecological studies spanning the period of Western colonization and development. This sedimentary deposit, and others like it, should be useful, albeit not ideal, for quantifying anthropogenic impacts on coral reef systems.

    Testing road surface treatments to reduce erosion in forest roads in Honduras. Cien. Inv. Agr. 36(3):425-432. Using forest roads produces more erosion and sedimentation than any other forest or agricultural activity. This study evaluated soil losses from a forest road in central Honduras over two consecutive years. We divided a 400-m segment of road into 8 experimental units, each 50 m in length. Four units were treated with Best Management Practices (BMPs) and four were left untreated. The BMP treatments included reshaping the road prism, installing culverts and reshaping of road ditches, compacting 20-cm layers of the road tread, crowning the road surface (3% slope, double drainage), longitudinal sloping (less than 12%), and adding a 10-cm layer of gravel (crush size = 0.63 cm). Soil movement was measured daily during the rainy seasons. The highest soil loss occurred in the control road, around 500 m3 km-1 per year, while the road treated with BMP lost approximately 225 m3km-1 per year. These results show that road surface erosion can be reduced up to 50% with the implementation of surface treatments.

    2017-10-01

    The recent computations by 2016A&A...588A..25M of the post-Asymptotic Giant Branch evolution show that the post-AGB phase is, at least, three to ten times faster than shown by previous evolutionary computations. The new models are also 0.1-0.3 dex brighter than the previous models with similar remnant masses. As a consequence the adoption of these models in future studies will have a significant impact in the determination of masses and ages of central stars of planetary nebulae. Preliminary studies suggest that the new models will help us to understand mysterious invariance of the cut-off of the planetary nebula luminosity function.

    Eridani is an active young K2V star (0.8 Gyr), which exhibits a short and long-term chromospheric cycles of 3 and 13-yr periods, between 1985 and 1992, the star went through a broad activity minimum, similar to the solar Maunder Minimum-state. Motivated by these results, we found in Eridani a great opportunity to test the solar cinematic dynamo model built in sraibman16. In this work we present the components of the magnetic fields in the stellar surface derived from the model. To contrast these results to the registry of activity obtained from stellar observations, we also computed an activity index associated to the magnetic field.

  17. Isotopic Investigation of Geologic and Anthropogenic Controls on Nutrient Loading in Malibu Creek Watershed, California

    NASA Astrophysics Data System (ADS)

    Harrison, M.; Hibbs, B. J.

    2015-12-01

    The upper portion of the Malibu Creek Watershed exposes the Monterey-Modelo Formation, a Miocene marine mudstone. This formation has been thought to contribute high concentrations of orthophosphate and nitrate to streams via groundwater leaching and baseflow. However, our recent studies suggest that high concentrations of orthophosphate and nitrate may be dominated by dry weather runoff of imported water (tap and recycled water) from watering of urban landscapes. Our study investigates El Camino Real Creek, a tributary in the Malibu Creek Watershed that traverses Monterey-Modelo Formation strata and is fed predominantly by dry weather runoff. From an initial input at a storm drain where dry weather runoff flows consistently, hydrochemical parameters range from 1.86 to 4.66 mg/L NO3-N and 1.06 to 2.28 mg/L PO4 that decrease to concentrations ranging from 0.15 to 0.59 mg/L NO3-N and 0.40 to 0.87 mg/L PO4 where El Camino Real Creek converges with Las Virgenes Creek. The decrease in nutrient content downstream is due to the transformational processes denitrification, vegetation uptake, and mixing with groundwater baseflow containing lower nutrient content. The average water isotope values for the imported (tap and recycled) endmembers are -9.1‰ δ18O and -73‰ δD. The average water isotope values for the samples collected at the storm drain range from -6.0‰ to -8.0‰ δ18O and -56‰ to -68‰ δD while isotope values downstream range from -6.0‰ to -6.3‰ δ18O and -47‰ to -48‰ δD. Stable isotopes of hydrogen and oxygen show mixing of imported water with local groundwater downstream, which demonstrates that nutrients in this creek are not strictly dominated by geologic sources. To further understand the nutrient changes and mixing percentages of imported and local water sources, diurnal studies are being conducted with the integration of nitrate isotopes to help understand the nutrient dynamics in El Camino Real Creek.

    2016-08-16

    Introduccion. La conciencia es el resultado de una serie de procesos neurobiologicos en el cerebro y a su vez es un rasgo del nivel de su complejidad. En realidad, el estar y el ser consciente nos situan ante lo que Chalmers ha denominado el 'problema blando' y el 'problema duro' de la conciencia. El primero hace referencia a aspectos como la vigilia, la atencion o el conocimiento, y el segundo a conceptos tan complejos como autoconciencia, 'yo neural' o cognicion social. En este sentido se puede afirmar que el concepto de conciencia como algo unitario plantea problemas de acercamiento a una realidad sumamente compleja. Desarrollo. Planteamos los principales modelos que desde una perspectiva neurocientifica han abordado el tema de la conciencia. Por un lado, los modelos de experiencia consciente de Crick, Edelman y Tononi, y Llinas, y por otro, los modelos y las bases neuronales de la autoconciencia de autores como Damasio (conciencia central y extendida), Tulving (conciencia autonoetica, noetica y cronestesia), el problema de los qualia (Dennett, Popper, Ramachandran) y el modelo de los cognitos (Fuster). Conclusiones. Todos los estimulos que recibimos del mundo externo y de nuestro mundo interno son convertidos y tratados por el cerebro para integrarlos y que formen parte de nuestra identidad. Desde la percepcion de un perro y reconocerlo como tal hasta la comprension de la propia conciencia responden al funcionamiento de estructuras cerebrales, neuronas y sinapsis. Ahora bien, los procesos mas complejos de la conciencia, como la autoconciencia o la empatia, son probablemente procesos emergentes del cerebro.

    Observations of the long-term spectroscopic behaviour from 1971 to 2001 of the late type Be star Pleione (HD 23862) are presented. From the characteristics of the Hβ line emission component, the variable physical properties of the circumstellar envelope of the star are studied. We used Huang's relation for a Keplerian movement to get a first estimate of the size of the disc and a simple emitting ring like model to infer the envelope physical parameters that can explain the observed emission intensity as well as the Hβ emission line profile. The enhancement of the ``shell" spectroscopic aspects seem to be produced by a shrinked circumstellar envelope. The emission observed since 1994 cannot be accounted for by a strongly flattened circumstellar envelope.

    Temephos in domestic water containers remains a mainstay of Latin American government programmes for control of Aedes aegypti and associated illnesses, including dengue. There is little published evidence about coverage of routine temephos programmes. A cluster randomised controlled trial of community mobilisation in Mexico and Nicaragua reduced vector indices, dengue infection, and clinical dengue cases. Secondary analysis from the Mexican arm of the trial examined temephos coverage and beliefs, and the impact of the trial on these outcomes. The trial impact survey in December 2012, in 10,491 households in 45 intervention and 45 control clusters, asked about visits from the temephos programme, retention of applied temephos, and views about temephos and mosquito control. Fieldworkers noted if temephos was present in water containers. Some 42.4% of rural and 20.7% of urban households reported no temephos programme visits within the last 12 months. Overall, 42.0% reported they had temephos placed in their water containers less than 3 months previously. Fieldworkers observed temephos in at least one container in 21.1% of households. Recent temephos application and observed temephos were both significantly more common in urban households, when other household variables were taken into account; in rural areas, smaller households were more likely to have temephos present. Most households (74.4%) did not think bathing with water containing temephos carried any health risk. Half (51%) believed drinking or cooking with such water could be harmful and 17.6% were unsure. Significantly fewer households in intervention sites (16.5%) than in control sites (26.0%) (Risk Difference - 0.095, 95% confidence interval - 0.182 to -0.009) had temephos observed in their water; more households in intervention clusters (41.8%) than in control clusters (31.6%) removed the applied temephos quickly. Although fewer households in intervention sites (82.7%) compared with control sites (86.7%) (RD -0.04, 95% CI -0.067 to -0.013) agreed temephos and fumigation was the best way to avoid mosquitoes, the proportion believing this remained very high. Coverage with the government temephos programme was low, especially in rural areas. Despite an intervention encouraging non-chemical mosquito control, most households continued to believe that chemicals are the best control method. ISRCTN: 27581154 .

    Introduccion. La ciencia y la filosofia han abordado a lo largo de la historia del pensamiento y desde diferentes perspectivas epistemicas el problema mente-cerebro. La primera de ellas acota areas especificas de la realidad y construye hipotesis de corto alcance y multiple conectividad intercientifica con el objetivo de validar modelos teoricos; la segunda extiende su arquitectura sistemica al conjunto de lo real (incluida la actividad cientifica). Desarrollo. La complejidad del problema mente-cerebro exige generar un vinculo de conexion disciplinar entre la filosofia y la ciencia; nuestros presupuestos ontoepistemologicos se erigen, por lo tanto, en el marco de una filosofia orientada cientificamente (filosofia cientifica). Se defiende el materialismo emergentista como solucion filosofico-cientifica coherente y contrastable en contraposicion a otras propuestas desarrolladas desde diferentes modelos ontologicos (por ejemplo, dualismo interaccionista, funcionalismo, teoria de la identidad, epifenomenalismo...). Conclusiones. La respuesta al problema mente-cerebro solo es factible desde una neurociencia cognitiva fundamentada filosoficamente: el materialismo emergentista –postulado ontologico– afirma que la mente es una propiedad emergente (novedad cualitativa) del cerebro; el realismo cientifico –postulado epistemologico– sostiene que la neurociencia cognitiva es la herramienta teorico-experimental basica que posibilita el acceso cognoscitivo tanto al cerebro como a sus procesos neurocognitivos. Consideramos que a partir de esta fundamentacion filosofica, la neurociencia cognitiva adquiere legitimidad epistemica para acometer el estudio del proceso mental mas genuinamente humano: la conciencia.

    This is a Spanish translation of 'User Guide for the International Jobs and Economic Development Impacts Model.' The International Jobs and Economic Development Impacts (I-JEDI) model is a freely available economic model that estimates gross economic impacts from wind, solar, and geothermal energy projects for several different countries. Building on the original JEDI model, which was developed for the United States, I-JEDI was developed under the USAID Enhancing Capacity for Low Emission Development Strategies (EC-LEDS) program to support countries in assessing economic impacts of LEDS actions in the energy sector. I-JEDI estimates economic impacts by characterizing the construction and operation of energy projects in terms of expenditures and the portion of these expenditures made within the country of analysis. These data are then used in a country-specific input-output (I-O) model to estimate employment, earnings, gross domestic product (GDP), and gross output impacts. Total economic impacts are presented as well as impacts by industry. This user guide presents general information about how to use I-JEDI and interpret results as well as detailed information about methodology and model limitations.

    Pivato, M. C.; Padilla, N. D.; García Lambas, D.

    We present a new method to determine the high order bias coefficients in the ellipsoidal collapse model, from the Eulerian overdensity of dark matter halos. The analytical model obtained is applied to the GIF cold dark matter numerical simulations (Kauffman et al. 1998). Our results indicate that the ellipsoidal collapse model gives a more accurate description of the mass function obtained from simulations than the spherical collapse model. Moreover, the hierarchical correlation amplitude, SJ,g, obtained from the bias coefficients shows a good agreement with the simulations in intermediate and large scales, while in small scales, the non-linear effects strongly influence the results.

    Models from stellar winds in one dimension (1-D) from massive stars, ro- tating at high velocities show an equatorial flux slower and denser (e.g., Be stars) than the standard solution (CAK, FA, PPK, see below). We analyse the time dependent wind equations for rotating stars with the hydrodynamic numerical code ZEUS-3D. These simulations agree with wind's steady state models, and we confirm that for high rotational velocities the flux has a slower and denser acceleration. We compared our solutions with the ones from Madura et al. (2007) and we find differences. Finally , we show the first time dependent calculations for new slow solutions which may explain the winds of BA Supergiants stars. FULL TEXT IN SPANISH

    Tirapu-Ustarroz, J; Cordero-Andres, P; Luna-Lario, P; Hernaez-Goni, P

    2017-01-16

    Introduccion. Desde que Lezak acuñara el termino de funciones ejecutivas como las capacidades mentales esenciales para llevar a cabo una conducta eficaz, creativa y aceptada socialmente, estas han adquirido progresivo protagonismo en la investigacion neuropsicologica. Diversos modelos han sido planteados para explicar su naturaleza, pero no existe consenso respecto a si nos encontramos ante un constructo unitario o un sistema de procesamiento multimodal con componentes independientes, pero interconectados. Para conocer la estructura de este constructo se han utilizado estudios de lesion, neuroimagen y, recientemente, el analisis factorial, que se plantea como una metodologia prometedora para ampliar nuestro conocimiento sobre un concepto tan generico como las funciones ejecutivas. Desarrollo. El proposito de este estudio es realizar una revision sistematica de modelos factoriales de atencion y control ejecutivo en adultos, entre los años 1991-2016, utilizando las bases de datos PubMed, OvidSP y PsycINFO. En total, se revisaron 33 articulos. A partir de la bibliografia, se realiza una propuesta integradora de los procesos ejecutivos. Conclusiones. Aunque no disponemos de un unico modelo que pueda explicar la complejidad de las funciones ejecutivas, si parece existir acuerdo respecto a su multidimensionalidad. En analisis factoriales, actualizacion, inhibicion y alternancia gozan de fuerte evidencia, si bien hay trabajos que plantean factores novedosos. Nuestra propuesta integradora trata de combinar los procesos ejecutivos hallados en la bibliografia con sus correspondientes correlatos neuroanatomicos, defendiendo que la metodologia ideal deberia utilizar informacion procedente de estudios de lesion, tecnicas de neuroimagen y modelos psicometricos-computacionales.

    A partir de la observación del espectro del quintuplete de C III alrededor de 1175 Å, se ha realizado el diagnóstico de la densidad y presión electrónica, basado en el cálculo del cociente de las intensidades observadas. Una vez establecida la densidad electrónica, y con el cálculo de las velocidades Doppler, hemos investigado el flujo de masa en la protuberancia en función de la temperatura. Estableciendo como hipótesis la conservación del número de partículas que ingresan y salen del cuerpo de la protuberancia, se investiga la variación del área de un tubo de flujo semi-empírico en función de la temperatura. A partir de dicho diagnóstico, se examina el comportamiento del radio del tubo magnético en función de la temperatura, los que dan cuenta de la abertura de las líneas de campo magnético que confinan el plasma y de la divergencia del campo magnético en diferentes alturas de la atmósfera solar.

  3. Modelos autoconsistentes de sistemas estelares cuspidales y triaxiales con distribución de velocidades casi isotrópica

    NASA Astrophysics Data System (ADS)

    Carpintero, D. D.; Muzzio, J. C.; Navone, H. D.; Zorzi, A. F.

    It has been shown in many works that it is possible to build stable, self-consistent models of triaxial stellar systems, even with cusps, and containing high percentages of chaotic orbits. Since all these models have been obtained from cold collapses, their velocity distributions are strongly radial. Also, chaos was computed using either Lyapunov exponents or SALI. However, models obtained by adiabatic deformation of spherical systems, in which the velocity distribution is more isotropic, showed a very low level of chaos, though it must be noted that the method of detecting chaos used in this case, namely the variation of orbital frequencies, is less sensitive than the abovementioned methods. In this work, we present models obtained by adiabatic deformation, in which we compute the fraction of chaotic orbits using both Lyapunov exponents and variation of orbital frequencies. Our results show that the percentages of chaotic orbits is significant, though they are smaller than those obtained in models with strong radial velocity components. FULL TEXT IN SPANISH

  9. From the Big Bang to the life in the primitive seas. (Spanish Title: Desde la Gran Explosión hasta la vida en los mares primitivos)

    NASA Astrophysics Data System (ADS)

    Esteban, S. B.

    Man has always wondered about the origins of humanity, life, and the world around him. The Earth crust is a vast and natural archive, and its rocks represent the pages of the most documented events in the geological past. These rocks hold large amounts of information about the Earth history, whose age is estimated to be 4,600 million years. Historical Geology seeks to bring together the knowledge of the origin of the Universe as well as the origin of Earth as a member of the Solar System. The Big Bang theory supposes that the Universe began with a huge explosion. In the Earth's history it is possible to differentiate the biological events from the physical ones. The physical events are geographical and environmental transformations. The biological events are related to life on Earth. There are evidences of biological processes back to 3,500 million years ago. At the beginning, the conditions on Earth were catastrophic and unstable. At this stage, the first signs of life were the molecules that started to take energy from the sunlight and the chemical products. It was not a simple accumulation of gradual biological forms, but was accompanied by episodic innovations that allowed increasing complexity and greater use of ecospace. Some of these innovations are shown by certain groups of primitive arthropods adapted to live in oxygen-poor, deep marine environments. These arthropods have been found in 500 million-year-old rocks in northwestern Argentina (provinces of Jujuy and La Rioja), indicating the presence of oxygen-poor seas in that region.

  10. El uso de las simulaciones educativas en la ensenanza de conceptos de ciencias y su importancia desde la perspectiva de los estudiantes candidatos a maestros

    NASA Astrophysics Data System (ADS)

    Crespo Ramos, Edwin O.

    This research was aimed at establishing the differences, if any, between traditional direct teaching and constructive teaching through the use of computer simulations and their effect on pre-service teachers. It's also intended to gain feedback on the users of these simulations as providers of constructive teaching and learning experiences. The experimental framework used a quantitative method with a descriptive focus. The research was guided by two hypothesis and five inquiries. The data was obtained from a group composed of twenty-nine students from a private Metropolitan University in Puerto Rico and elementary school pre-service teachers. They were divided into two sub-groups: experimental and control. Two means were used to collect data: tests and surveys. Quantitative data was analyzed through test "t" for paired samples and the non-parametric Wilcoxon test. The results of the pre and post tests do not provide enough evidence to conclude that using the simulations as learning tools was more effective than traditional teaching. However, the quantitative results obtained were not enough to reject or dismiss the hypothesis Ho1. On the other hand, an overall positive attitude towards these simulations was obtained from the surveys. The importance of including hands-on activities in daily lesson planning was proven and well recognized among practice teachers. After participating and working with these simulations, the practice teachers expressed being convinced that they would definitely use them as teaching tools in the classroom. Due to these results, hypothesis Ho2 was rejected. Evidence also proved that practice teachers need further professional development to improve their skills in the application of these simulations in the classroom environment. The majority of these practice teachers showed concern about not being instructed on important aspects of the use of simulation as part of their college education curriculum towards becoming teachers.

    RESUMEN:En este trabajo informamos la detecci6n de 20 erupciones en la li'nea de =18cm (1667MHz) del radical OH en el Cometa Halley.Las observaciones incluyen todos los monitoreos existentes y se extienden desde 120 dias antes del perihelio hasta 90 dias despues.Se detectan bruscos crecimientos en el flujo medido,hasta un factor 1O,seguidos por decaimientos lentos asociados con la fotodisociaci6n del OH. Se obtuvieron valores para el tiempo de vida fotoquimico del OH y del H2O basandose en el modelo desarrollado previamente por Silva(1988). Esos tiempos de vida estan de acuerdo con predicciones teoricas y con las observaciones en el Ultravioleta, y los resultados, los que son fuertemente dependientes de la velocidad heliocentrica del Coineta (variando hasta un factor 6), han sido calculados para varios rangos de velocidad entre +28 y -28 km/seg.

    Introduccion. Los niños con trastorno por deficit de atencion/hiperactividad (TDAH) experimentan dificultades sociales que afectan a su funcionamiento personal y academico. Objetivo. Revisar los estudios que han abordado la influencia de las habilidades cognitivas y afectivas implicadas en su adaptacion social, desde la perspectiva de un modelo integrador que incluye el funcionamiento ejecutivo, las habilidades mentalistas y el lenguaje pragmatico. Desarrollo. Las investigaciones revisadas constatan una asociacion entre funcionamiento ejecutivo (memoria de trabajo, inhibicion, planificacion), habilidad pragmatica y rendimiento en tareas mentalistas, con la problematica social que experimentan las personas con TDAH. Conclusiones. Aunque la bibliografia respalda una relacion entre estos constructos, los deficits observados en la ejecucion de tareas de teoria de la mente o en el uso del lenguaje parecen responder mas bien a un deficit de caracter procedimental y no tanto a dificultades de indole conceptual.

Objetivo. Comparar el coste-utilidad de los tres ACOD frente a los antivitamina K. Pacientes y metodos. Se utilizo un modelo Markov con ciclos trimestrales para simular pacientes con FANV desde que inician su tratamiento hasta el resto de su vida desde la perspectiva del Sistema Nacional de Salud. El modelo incorporo 36 estados de salud, incluyendo combinaciones de tratamientos, discapacidad y antecedentes de eventos, y considero una cohorte hipotetica de 10.000 pacientes con FANV. La eficacia relativa se calculo a partir de una comparacion indirecta formal de los tratamientos segun los datos de los ensayos pivotales de cada ACOD. Resultados. El dabigatran se asocio al valor maximo de años de vida ajustados por calidad (AVAC) (8,40 AVAC), seguido del apixaban (8,33 AVAC), el rivaroxaban (8,15 AVAC) y el acenocumarol (8,03 AVAC). Los costes totales fueron menores con el acenocumarol (22.230 €), seguido del dabigatran (24.564 €), el apixaban (24.655 €) y el rivaroxaban (25.900 €). La ratio coste-utilidad incremental frente a los antivitamina K fue de 6.397, 8.039 y 29.957 €/AVAC para el dabigatran, el apixaban y el rivaroxaban, respectivamente. Comparados entre ellos, el dabigatran domino al apixaban y al rivaroxaban. Los analisis de sensibilidad confirmaron la robustez del caso base. Conclusiones. Los tres ACOD son coste-efectivos frente al acenocumarol. El dabigatran es economicamente dominante frente al rivaroxaban y al apixaban en España, al ser mas efectivo y menos costoso.

    Introduccion. Pocos autores han comparado la vida y obra de Cajal y Pavlov, y, cuando lo hacen, se refieren generalmente a su coincidencia en el XIV Congreso Internacional de Medicina que tuvo lugar en Madrid en 1903. Objetivo. Presentar los modelos teoricos de ambos autores para estudiar la posible complementariedad entre sus teorias. Desarrollo. Se presentan las principales caracteristicas de la teoria neuronal de Cajal, la teoria reticular que le antecedio, los principales resultados de las investigaciones de Cajal y las aportaciones que brindo al concepto de plasticidad. En cuanto a la teoria de los reflejos condicionales de Pavlov, se describen sus principales postulados, las leyes pavlovianas y la tipologia del sistema nervioso segun Pavlov. Conclusiones. Los niveles de organizacion en los que trabajan Cajal y Pavlov se pueden entender como complementarios si tenemos en cuenta la propuesta de Henry Wallon o las de marcos epistemologicos como la epistemologia estrategica, donde el avance de la ciencia se logra desde estrategias diferentes, pero complementarias, que ayudan a construir modelos teoricos mas fuertes.

  2. Dinámica de planetas extrasolares resonantes

    NASA Astrophysics Data System (ADS)

    Beauge, C.

    Actualmente se han detectado 117 planetas alrededor de estrellas de Secuencia Principal, incluyendo 12 sistemas planetarios, cada uno con dos o tres miembros. De estos últimos, ocho poseen planetas en órbitas próximas y sus perturbaciones gravitacionales se convierten en un factor fundamental para la estabilidad orbital del sistema. Todos se encuentran en configuraciones resonantes, desde la conmensurabilidad de movimientos 2/1 de Gliese 876, hasta la resonancia secular de Ups And. En esta presentación analizamos varios aspectos de la dinámica resonante de los planetas extrasolares, incluyendo la existencia de soluciones de equilibrio, construcción de modelos analógicos y métodos para la determinación de masas individuales. También discutimos por qué las resonancias son tan frecuentes en estos sistemas, comparado con nuestro propio Sistema Solar. Por último, intentamos relacionar estos modelos con la hipótesis de migración planetaria, buscando límites en su extensión y en los posibles mecanismos que le dieron origen.

  3. Morfología de la Coma del Cometa Hale - Bopp

    NASA Astrophysics Data System (ADS)

    Gil-Hutton, R.; Caballero, M.; Coldwell, G.; Cañada, M.; Godoy, G.; Trozzo, C.; Gómez, G.

    Para lograr comprender plenamente los procesos físicos que se desarrollan en los núcleos cometarios y obtener un modelo que explique, no sólo su actividad, sino también sus efectos sobre la coma, es necesario obtener información detallada para el mayor número de cometas posible, siendo las características más interesantes para estudiar la ubicación de las regiones activas, la presencia de jets, las tasas de producción de gas y polvo y la interacción de la coma con el viento solar. En la actualidad, con técnicas de procesamiento de imágenes y tecnología CCD se pueden obtener este tipo de datos para cometas que ingresan al sistema solar interior y estudiar, de esta manera, la morfología de sus comas, tratando de correlacionar la actividad detectada con algún modelo teórico. En este trabajo se presenta un estudio parcial de la actividad desarrollada por el cometa Hale-Bopp, y sus efectos sobre la morfología de su coma, desde agosto de 1995 hasta la fecha en base a imágenes adquiridas con el telescopio de 0.76 m. de la Estación Astronómica Dr. Carlos Ulrrico Cesco.

    Introduccion. La lesion medular es un evento catastrofico, cuyas consecuencias persisten durante toda la vida del paciente. La investigacion en tratamiento se ha basado principalmente en el desarrollo de terapias que reduzcan la discapacidad, pero desde los anos noventa hay un avance significativo y se han probado varios trasplantes celulares en modelos animales de lesion medular, celulas de Schwann, astrocitos y celulas de la glia envolvente olfatoria (CGEO). Objetivo. Hacer un recuento detallado de la patogenia de la lesion medular primaria y secundaria y de los mecanismos por los cuales las CGEO inducirian sus posibles efectos regenerativos descritos en la bibliografia. Desarrollo. Despues del traumatismo, la lesion se desarrolla en dos fases, la primaria se caracteriza por las lesiones de compresion y la secundaria se produce por una serie de factores que se dan en paralelo y que incluyen factores vasculares, celulares, moleculares y formacion de cicatriz glial. La mayoria de los modelos de lesion medular y trasplante con CGEO han comunicado recuperacion funcional, remielinizacion y regeneracion axonal. Estas celulas ejercen su accion de manera indirecta a traves de la produccion de factores de crecimiento y de manera directa induciendo regeneracion neuronal, axonal y remielinizacion. Conclusiones. Las CGEO son una opcion terapeutica en pacientes con lesion medular debido a que inducen de modo directo o indirecto regeneracion neuronal, axonal, remielinizacion de axones, disminucion de cicatriz glial y otros efectos que conducen a la recuperacion funcional.

    This work provides the results of a survey of entomonematodes parasites of grasshoppers in grasslands of the Pampean Region, Argentina. Nymphs of Staurorhectus longicornis Giglio-Tos, Laplatacris dispar Rhen, 1939, Dichroplus elongatus Giglio-Tos, 1894 and Metaleptea brevicornis (L.) (Orthoptera: Acrididae) were collected. Mermithidae was the only family registered with seven species: Agamermis decaudata Cobb, Steiner and Christie, 1923, Amphimermis bonaerensis Miralles and Camino, 1983, Amphimermis dichroplusi Camino and Lange, 1997, Amphimermis ronderosi Camino and Lange, 1997, Hexamermis coclhearius Stock and Camino, 1992, Hexamermis ovistriata Stock and Camino, 1992, and Longimermis acridophila Camino and Stock, 1989. The values of parasitism ranged between 1-12%, and intensity not overcome the number of 5.0 nematodes per larva. The nematodes observed showed specificity, not registering the same species of parasite in more than one host species. The Pampean region constituted an area with high diversity of mermithids where new species could be consider as bioregulator agents of this troublesome insect pests in agricultural areas of Argentina.

  1. Sobre a largura da última superfície de espalhamento

    NASA Astrophysics Data System (ADS)

    Nobre, M. A. S.; Pires, N.; Lima, J. A. S.

    2003-08-01

    De acordo com o modelo do "Big-Bang", no universo primordial a matéria estava em equilíbrio térmico com a radiação. Com a expansão a temperatura da radiação cai. Quando a temperatura chega em torno dos 4.000K, os espalhamentos diminuem, começando a recombinação dos prótons e elétrons em Hidrogênio neutro (era conhecida como da recombinação). Ao final da recombinação, os fótons se propagam livremente sofrendo, em princípio, somente os efeitos do "redshift" cosmológico. Esses fótons nos alcançam hoje como a radiação cósmica de fundo (RCF), e parecem vir de uma superfície esférica ao nosso redor, tal que o raio dela é a distância que ele viajou desde seu último espalhamento na época da recombinação. Naturalmente, esse processo não ocorreu abruptamente, implicando na existência de uma largura no espaço dos "redshifts" que deve depender do modelo cosmológico específico e dos processos físicos considerados. Neste trabalho analisamos os efeitos de diferentes modelos - a saber, aqueles com decaimento do vácuo L(t), criação de matéria, quintessência e gás de Chaplygin - sobre a última superfície de espalhamento da RCF, em particular sua largura e a função visibilidade, que determina a probabilidade de um fóton ter tido seu último espalhamento num "redshift" z. No caso particular dos modelos com decaimento do vácuo, existe uma forte dependência da função visibilidade com L(t). Tais efeitos poderão ser testados através da análise dos resultados de experimentos mais precisos que estão atualmente em andamento, como por exemplo, o WMAP.

  2. Comparacion de modelos de Educacion Sexual en el conocimiento y cambio de actitudes en practicas sexuales por alumnos de nivel superior en la region de Caguas, Puerto Rico

    NASA Astrophysics Data System (ADS)

    Juan, Vallejo Ramos L.

    In opposition to the Sexual Education Traditional Model (SETM) that is used in the state schools of Puerto Rico, the Health Beliefs Model (HBM) appears. It facilitates a curricular design that improves the ability of the students to respond to the group pressure by means of attitudes that stimulate sexual conducts of smaller risk of propagation of the Sexually Transmitted Diseases (STD). In addition, it provides activities to increase the self-esteem, the communication and the decision making. This investigation had the intention to compare the SETM and the HBM in the increase of knowledge and change of attitudes of high risk of propagation of the STD using a validated questionnaire (Agency of the United States for the International-USAID Development), named "Endesa 2007" and, adapted to Puerto Rico by the Dra.Marta Collazo to a sample of students between the 17 and 19 years of 2 state schools of San Lorenzo, as a pretest, and, selected by convenience. Then, a 10 hours training was administered to half of the students using the SETM to STD and condom use lessons. The other half of the students received additional lessons using the HBM. Finally, both groups took the questionnaire again as a posttest. The sample of students, in average, did not reach the knowledge and basic levels of attitudes towards the STD in the pretest. This reflected 2 possible implications on the SETM. In first place, that the way in which the STD is implemented as part of the Sexual Education curriculum is inefficient. Secondly, the possibility that the acquired information or attitudes does not have permanence. Culminated the questionnaire, the HBM increase the knowledge of the STD in 0.41 points (average) over the SETM. There was not a significant difference between both models, in attitudes, implying that both models are equally effective. The findings suggests that the HBM is more effective increasing the knowledge on the STD, but equally effective than the SETM in attitude change for the Puerto Rican youth.

    We present new results of our evolutionary-explosive- composite model of Galaxies, Quasars and AGNs. In particular: we explain the concept of final phase of a galaxy and the fact that at least a fraction of dwarf galaxies can be explained by this model (as a stage prior to the final). In addition, we explain that the prototype of the starburst galaxy M82 could be a dwarf galaxy previous to the final phase. Also, we discuss new Gemini observations BAL + FeII + IR medium-high redshift QSOs. To interpret these results we performed an introduction to our model and some of the most previous relevant results, including: (i) Evolution Diagram of Galaxies, QSOs and AGNs; (ii) Our Evolutionary-Explosive-Compound Model explains in the same process: the interaction of ``Starburst'' and Supermassive black holes that generate hypernova, the Origin of Ultra Energetic Cosmic Rays and Dark Matter. (iii) Observation and Theory of Formation and Final Phase of Galaxies via hypernova explosions in QSOs and AGNs.

    Recently in our Observatory we have developed a new Stellar Pulsation Code, independently of other workers. Such program computes eigenvalues (eigenfrequencies) and eigenfunctions of non-radial modes in spherical non-perturbated stellar models. To accomplish this calculations, the four order eigenvalue problem (in the linear adiabatic approach) is solved by means of the well-know technique of Henyey on the finite differences scheme wich replace to the differential equations of the problem. In order to test the Code, we have computed numerous eigenmodes in polytropic configurations for several values of index n. In this comunication we show the excelent agreement of our results and that best available in the literature. Also, we present results of oscillations in models of white dwarf stars with homogeneus chemical composition (pure Helium). This models have been obtained with the Evolution Stellar Code of our Observatory. The calculations outlined above conform a first preliminary step in a major proyect whose main purpose is the study of pulsational properties of DA, DB and DO white dwarfs stars. Detailed investigations have demonstrated that such objets pulsates in non-radial g-modes with eigenperiods in the range 100-2000 sec.

    Impacts of climate change on the hydrologic processes under future climate change conditions were assessed over Muda and Dungun watersheds of Peninsular Malaysia by means of a coupled regional climate and physically-based hydrology model utilizing an ensemble of future climate change projections. An ensemble of 15 different future climate realizations from coarse resolution global climate models' (GCMs) projections for the 21st century was dynamically downscaled to 6km resolution over Peninsular Malaysia by a regional climate model, which was then coupled with the watershed hydrology model WEHY through the atmospheric boundary layer over Muda and Dungun watersheds. Hydrologic simulations were carried out at hourly increments and at hillslope-scale in order to assess the impacts of climate change on the water balances and flooding conditions in the 21st century. The coupled regional climate and hydrology model was simulated for a duration of 90years for each of the 15 realizations. It is demonstrated that the increase in mean monthly flows due to the impact of expected climate change during 2040-2100 is statistically significant from April to May and from July to October at Muda watershed. Also, the increase in mean monthly flows is shown to be significant in November during 2030-2070 and from November to December during 2070-2100 at Dungun watershed. In other words, the impact of the expected climate change will be significant during the northeast and southwest monsoon seasons at Muda watershed and during the northeast monsoon season at Dungun watershed. Furthermore, the flood frequency analyses for both watersheds indicated an overall increasing trend in the second half of the 21st century.

    Introduccion. El tratamiento de las crisis epilepticas prolongadas requiere disponer de una medicacion de rescate comoda, segura y efectiva. Actualmente, el tratamiento estandar en la comunidad es el diacepam rectal. La introduccion de una solucion bucal de midazolam abre una perspectiva nueva en el tratamiento. Objetivo. Evaluar el coste-efectividad del midazolam bucal respecto al diacepam rectal para los niños con un diagnostico de epilepsia que presentan crisis convulsivas prolongadas en la comunidad en España. Materiales y metodos. Modelo coste-efectividad desde la perspectiva del Sistema Nacional de Salud (SNS) español, con resultados presentados en terminos de costes y años de vida ajustados por calidad. Los datos se obtuvieron de varias fuentes, incluidas las estimaciones de efectividad clinica de un ensayo clinico, de un panel Delphi en España y de una encuesta nacional a padres de niños con epilepsia para determinar las practicas actuales. Resultados. El tratamiento con midazolam bucal produce un ahorro de costes en comparacion con el diacepam rectal. El ahorro para el SNS español es de 5.484 euros por paciente al año. El tratamiento con midazolam bucal ofrece una mejora en la calidad de vida relacionada con la salud. Esto, unido al ahorro de costes, hace que el midazolam bucal sea dominante frente al diacepam rectal en todos los escenarios examinados. Conclusion. Los resultados del modelo muestran que el midazolam bucal es mas coste-efectivo que el diacepam rectal debido a una reduccion en la necesidad de llamadas a la ambulancia y estancias en el hospital, asi como a una mejora en la calidad de vida relacionada con la salud.

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

    Introducción: Las ratas Wistar son una de las cepas más populares y utilizadas cotidianamente para la investigación en el laboratorio sirviendo como una importante herramienta de investigación, por lo que, exige el control estricto de variables como la edad, el sexo y el peso corporal, y de esta forma poder extrapolar los resultados al modelo humano. Objetivo: Desarrollar curvas de referencia para valorar el crecimiento físico de ratas machos Wistar en función de la edad cronológica y la maduración somática desde una perspectiva no-invasiva. Metodología: Fueron estudiadas 731 ratas machos Wistar de forma transversal. Se evaluó la edad, peso corporal y la superficie corporal. Se utilizó el método LMS para construir curvas de percentil en función del peso y la maduración somática. Resultados: Las curvas de crecimiento físico propuestas sirven para realizar el seguimiento del crecimiento físico y el diagnóstico del estado nutricional de ratas machos de cepa Wistar. Los puntos de corte prepuestos son: P3, P10, P25, P50, P75, P90 y P97. Conclusión: Los resultados sugieren que los científicos de diversas áreas puedan usar tales referencias, con el objetivo de extrapolar las fases del crecimiento somático de la rata de laboratorio al modelo humano y es una alternativa no-invasiva para valorar el crecimiento y el estado nutricional.

    Introducción: la impulsividad es un rasgo de personalidad relacionado con el control de la conducta y de las emociones y que se observa en diferentes alteraciones psicopatológicas, entre ellas las referidas a la conducta alimentaria. Objetivo: el objetivo del presente trabajo fue analizar la relación entre la infl uencia del modelo estético corporal, la conducta alimentaria (y riesgo de patología específi ca), el IMC y la impulsividad.Método: fueron incluidos en el estudio 178 varones con una edad media de 20,18 ± 2,48 años. De todos ellos se recogieron peso y talla para calcular el IMC, y los participantes cumplimentaron la escala de impulsividad de Barratt (BIS-11), el Cuestionario de Infl uencias del Modelo Estético Corporal, versión para varones (CIMEC-V) y el Eating Attitudes Test-40(EAT-40).Resultados: se encontró un 5,06% de posibles casos de trastornos alimentarios. Las puntuaciones en algunos ítems de la BIS-11 correlacionaron significativamente con las puntuaciones del EAT-40 y CIMEC-V. Los participantes en situación de sobrepeso (39,89%) presentaron mayor impulsividad, al igual que ocurrió con los participantes que obtuvieron una puntuación superior al punto de corte en el EAT-40.Conclusiones: la exploración de la impulsividad desde el punto de vista psicológico podría constituir un elemento preventivo con relación a las alteraciones alimentarias. En cuanto a pacientes con TCA/sobrepeso/obesidad, podría ser un aspecto a destacar de cara a mejorar su abordaje terapéutico.

    Objetivo: Estimar el coste-efectividad (CE) de belimumab en aquellos pacientes con biomarcadores positivos y enfermedad activa a pesar del tratamiento estandar (TE) desde la perspectiva social espanola. Métodos: A partir de un modelo de microsimulacion, que permite simular la evolucion natural de la enfermedad, se estimo el CE de belimumab + TE vs. TE. Se considero una duracion del tratamiento de dos anos y un horizonte temporal de toda la vida. La extrapolacion de eficacia a largo plazo se baso en los ensayos clinicos de belimumab y en la cohorte de pacientes John Hopkins de Estados Unidos; los datos de utilidades se obtuvieron de la literatura. Se calcularon costes directos e indirectos en base a datos espanoles publicados (€, 2014), aplicando una tasa de descuento (TD) del 3% tanto a costes como a efectos. Los resultados se expresaron como ratio coste- efectividad incremental (ICER) en terminos de anos de vida ganados (AVG) y anos de vida ajustados por calidad (AVAC). Se realizaron analisis de sensibilidad deterministicos (TD al 0% y 5%, duracion de tratamiento 5 anos y exclusion de costes indirectos) asi como probabilisticos (PSA). Resultados: El ICER de belimumab + TE vs. TE fue de 16.647€/ AVG y 23.158€/AVAC respectivamente. La variacion de la TD supuso la mayor variacion de los resultados respecto al escenario base. En el 68% de los escenarios simulados en el PSA, belimumab fue una alternativa coste-efectiva considerando como umbral 30.000€/AVAC. Conclusiones: Belimumab puede considerarse una alternativa coste-efectiva desde la perspectiva social espanola.

    Gamma-ray astronomy opened the universe of the more energetic electromagnetic radiation using ground and orbiting instruments, which provide information for the understanding of sources of different types. Ground-based telescope arrays use Cherenkov light produced by the charged particles from extensive air showers generated in the Earth's atmosphere to identify gamma rays. This imposes a minimum energy threshold on the gamma rays to be detected. Towards the high-energy end of the spectrum, however, the amount of Cherenkov radiation produced by a gamma-ray photon guarantees its detectability, the limiting factor being the low flux of the sources. For this reason, the detection strategy consists in using arrays of small telescopes. In this work, we investigate the feasibility of detecting gamma-ray cascades using Cherenkov telescopes, in the range of 100 GeV to 2 TeV, at the CASLEO site, characterizing the response of a system of three Cherenkov telescopes.

    Este trabajo de investigacion supone un modelo teorico de caracter aplicado, que proporciona la oportunidad de evaluar la produccion cientifica de los investigadores. Se encuadra dentro de la tradiccion de la estadistica aplicada y la sociologia del conocimiento. Atiende especialmente a dos conjuntos de temas de interes, por una parte, las caracteristicas principales que determinan el nivel y tipo de produccion academica producida por las unidades de investigacion y por los propios investigadores; por otra, la utilizacion que se hace de los metodos y tecnicas de investigacion puesto que de ello tambien depende el modo de produccion cientifica. Los puntos novedosos de esta tesis son: la medicion cuantitativa del objeto de estudio, la suma de los productos y las condiciones externas a la produccion del conocimiento mas otros elementos internos como las caracteristicas de los investigadores y la metodologia utilizada para desarrollar sus trabajos; y, finalmente, el uso de las nuevas tecnologias. El aprovechamiento de los recursos estadisticos y las fuentes de informacion secundarias se complementan con el diseno propio de una encuesta donde se implementa las caracteristicas descritas en un capitulo anterior sobre los metodos cientificos mas idoneos descritos en los principales manuales y articulos cientificos desde distintas disciplinas de conocimiento. Dicha encuesta ha sido desarrollada como un programa propio y en base a los mas innovadores usos de la tecnologia en la metodologia de encuestas.

    El plasma de la corona solar es un buen indicador de las líneas de fuerza del campo magnético. Por lo tanto, el análisis de estructuras coronales cuasiestacionarias en la corona da importante información sobre el campo magnético y la actividad asociada. Se trata de poner límites a los modelos teóricos existentes mediante el estudio de distintas estructuras en la corona interior. En agosto de 1997 comenzó a operar el coronógrafo solar (MICA) en El Leoncito como parte del Observatorio Solar Alemán-Argentino. Desde su instalación obtiene imágenes de la corona solar (1.05 a 2.0 radios solares) en 2 líneas espectrales correspondientes a la emisión de Fe XIV y Fe X. El instrumento puede obtener imágenes cada minuto por lo que es ideal para estudiar procesos rápidos. Presentamos observaciones recientes que muestran la capacidad del coronógrafo así como la evolución de algunos eventos dinámicos observados por MICA.

    Introduccion. La epilepsia es una enfermedad cronica que implica un seguimiento periodico del paciente a largo plazo, lo que supone un aumento del numero de pacientes visitados con el tiempo y, por tanto, un coste al sistema sanitario. Objetivo. Determinar los factores implicados en el tiempo para la siguiente visita de un paciente epileptico. Pacientes y metodos. Seleccion de pacientes durante un ano que acuden consecutivamente a consulta de epilepsia de nuestro hospital. Se analiza su situacion clinica y relacion con el consejo medico dado, y los factores implicados en el tiempo transcurrido hasta la siguiente visita mediante modelos econometricos predictivos. Resultados. Existe una clara asociacion entre la situacion clinica del paciente y la modificacion del tratamiento propuesta por el neurologo en la visita anterior. Los factores implicados en el tiempo hasta la siguiente visita fueron frecuencia de crisis, efectos adversos medicamentosos, sobre todo los que afectan a la cognicion, y consejo medico al paciente. No resultaron significativos la politerapia, los trastornos psicoafectivos ni la situacion social del paciente. Conclusiones. El seguimiento en una consulta especifica de epilepsia mejora la situacion del paciente. Se trata del primer analisis de demanda asistencial en pacientes con epilepsia realizado mediante metodos econometricos y desde una perspectiva mixta medico-paciente. Dado que los factores que determinan el tiempo para la siguiente visita son modificables, podria disminuir el numero de visitas al ano, mejorando la situacion clinica de los pacientes. Proponemos una mayor duracion por visita para poder incidir en ello y reducir costes a largo plazo.

    RESUMEN. A nivel cosmol6gico pensamos que se ha estado prodticiendo radiaci6n gravitacional en cantidades considerables dentro de las galaxias. Si los eventos prodnctores de radiaci6n gravitatoria han venido ocurriendo desde Ia epoca de Ia formaci6n de las galaxias, cuando menos, sus efectos cosmol6gicos pueden ser tomados en cuenta con simplicidad y elegancia al representar la producci6n de radiaci6n y, por consiguiente, su interacci6n con materia ordinaria fenomenol6gicamente a trave's de una ecuaci6n de estado politr6pica, como lo hemos mostrado en otros trabajos. Presentamos en este articulo resultados nunericos de este modelo. ABSTRACT A common believe in cosmology is that gravitational radiation in considerable quantities is being produced within the galaxies. Ifgravitational radiation production has been running since the galaxy formation epoch, at least, its cosmological effects can be assesed with simplicity and elegance by representing the production of radiation and, therefore, its interaction with ordinary matter phenomenologically through a polytropic equation of state as shown already elsewhere. We present in this paper the numerical results of such a model. K words: COSMOLOGY - GRAVITATION

    Ortiz Benavides, Fedra Lorena

    El proposito de la investigacion fue evaluar la efectividad de una actividad de aprendizaje basado en la argumentacion dialogica en linea y su incidencia en el desarrollo de competencias cientificas. Se fundamenta en la teoria del aprendizaje socio cultural de Vigotsky (1984), los principios del diseno instruccional de la cognicion situada por Hung y Der-Thang (2001) y como estrategia se aplico la argumentacion dialogica utilizando el Modelo Argumentativo de Toulmin MAT (1984). El diseno experimental comparo dos grupos de estudiantes A y B en el curso virtual de Biotecnologia. El grupo A (experimental) desarrollo la discusion a partir de la estrategia disenada para este estudio y el grupo B (control) realizo la discusion desde las actividades tradicionales. El desarrollo de la competencia argumentativa se valoro con el instrumento de evaluacion para argumentacion dialogica en linea propuesta por Clark y Sampson (2008). La evaluacion de las competencias cientificas se realizo a partir de una postprueba. Los datos fueron analizados con pruebas estadisticas no parametricas. Los resultados de la investigacion, indicaron diferencias significativas en el nivel de la competencia argumental en el grupo experimental en comparacion al grupo control. Igualmente se demostro que existe una relacion positiva entre el nivel de desarrollo de la competencia argumentativa y el nivel de desarrollo de las competencias cientificas.

  13. Los retos de la educación bilingüe en inglés y español en las escuelas públicas de Nueva York: objetivos, modelos y currículos

    Velasco, Patricia; Cancino, Herlinda

    2012-10-01

    The challenges of bilingual education in English and Spanish in public schools of New York: Objectives, models and curricula - The first section of this article describes the conceptual differences between educational objectives, educational model (context and structures) and curriculum (units of study or sequential study guides). The second section analyses how these three concepts were put into practice in five bilingual elementary schools serving immigrant students in New York City. The educational objectives reflect the leadership and work expectations which the principal establishes within the school and with the community. The educational model is translated into a clear language allocation policy that is reached by consensus between the principal and the teachers. The curriculum adaptations reflect the context and culture of the students, but without neglecting the educational objectives. The development of academic language (the language based on academic texts) is an element that attracts vast interest in American schools, but is ignored in many bilingual ones. The development of academic language occupies a central role in the curriculum of these five schools. This is, to a great extent, the result of the limited exposure to literacy that many students have had outside of the school environment. The final section of this article describes how these schools disregard the antagonism towards immigrants and bilingual education that is currently characteristic of the United States and focus on the quality of their programmes.

    2016-08-01

    The cosmic microwave background radiation is one of the most powerful tools to study the early Universe and its evolution, providing also a method to test different cosmological scenarios. We consider alternative inflationary models where the emergence of the seeds of cosmic structure from a perfect isotropic and homogeneous universe can be explained by the self-induced collapse of the inflaton wave function. Some of these alternative models may result indistinguishable from the standard model, while others require to be compared with observational data through statistical analysis. In this article we show results concerning the first Planck release, the Atacama Cosmology Telescope, the South Pole Telescope, the WMAP and Sloan Digital Sky Survey datasets, reaching good agreement between data and theoretical predictions. For future works, we aim to achieve better limits in the cosmological parameters using the last Planck release.

  6. Modelizacion, control e implementacion de un procesador energetico paralelo para aplicacion en sistemas multisalida

    NASA Astrophysics Data System (ADS)

    Ferreres Sabater, Agustin

    Cualquier sistema electronico que incluya un procesado o tratamiento de la senal, y ademas, algun tipo de actuador mecanico generalmente necesita, como minimo, dos tensiones diferentes de alimentacion. Excluyendo los sistemas de alimentacion distribuida, la solucion tecnica mas utilizada para proporcionar dos o mas tensiones consiste en las fuentes de alimentacion multisalida. En una fuente de alimentacion multisalida los diferentes circuitos que conforman cada salida comparten un mismo transformador de potencia optimizando coste, masa, y volumen. Las ventajas obtenidas con este procedimiento tienen en su contra el efecto que sobre cada salida individual provocan las demas en su conjunto debido, principalmente, a los efectos de los elementos parasitos de los componentes. Un cambio de carga en una de las salidas produce un transitorio que es visto por todas las demas como un efecto de impedancia cruzada, y al final del transitorio, la tension de cada salida es diferente respecto a la que tenian antes del transitorio. Este ultimo resultado se conoce como regulacion cruzada. La disminucion de los efectos de la regulacion cruzada ha sido objeto de estudio durante los ultimos anos. El objetivo ha sido el desarrollo de distintas estrategias que permiten, desde disminuir los efectos de la regulacion cruzada hasta los niveles deseables, a eliminarla completamente. El resultado final suele suponer una penalizacion sobre el diseno del sistema directamente proporcional al grado de regulacion a conseguir en las distintas salidas. Entre las soluciones propuestas para eliminar la regulacion cruzada las tecnicas de post-regulacion se han consolidado como la opcion mas aceptada ya que, pueden aplicarse a cualquier convertidor y no suponen ninguna complejidad adicional a la hora de plantear el diseno. En esta Tesis Doctoral se abordara el estudio de la tecnica conocida como postregulacion mediante transformador controlado, que si bien se ha empleado en convertidores resonantes, su

    Introducción: Estudios nacionales de evolución temporal encuentran que la tendencia del consumo alimentario se asocia con aumento de la prevalencia de las enfermedades crónicas. Objetivos: Caracterizar los hábitos alimentarios de los adolescentes en un área urbana del Noreste de Brasil, relacionándolos con los marcadores dietéticos saludables. Métodos: Estudio transversal con adolescentes (n=430) de las escuelas públicas de Natal-RN, Brasil. El consumo alimentario se evaluó mediante dos recordatorios 24h. La técnica de Análisis de Componentes Principales fue utilizada para derivar patrones dietéticos, de acuerdo con: alimentos en gramos (g), la energía en Kcal y la fibra en gramos, lo que resulta, respectivamente, en 3 componentes principales distintos: 7, 8 y 4 (varianza acumulada >70%; cargas factoriales >0,4). La asociación entre las variables independientes y los escores de los factores de todos los componentes obtenidos, se determinó por la razón de prevalencia (IC 95%). Resultados: Los patrones dietéticos fueron: el (1) Sistema Alimentario Tradicional puro representó el primero componente de los modelos; el (2) Sistema Alimentario Combinado y de riesgo reveló marcadores de alimentación no saludables, debido a la alta frecuencia de azucares refinados, grasas saturadas y sal; y el (3) Sistema Alimentario Modificado fue identificado en el modelo de las fibras, el patrón 1 de nuevo fue observado en este patrón. Las asociaciones observadas, en particular del patrón SATm, distinguen por sexo, edad y estado nutricional. Conclusiones: Los patrones dietéticos 1 y 3 se caracterizaron por la preservación de las prácticas regionales de alimentos, muy saludables, desde el punto de vista de la prevención de las enfermedades crónicas, mientras que el 2 representó alerta y riesgo para la salud. Los hallazgos pueden subvencionar Políticas de Atención a la Salud para infancia y adolescencia en carácter intersectorial.

  8. Health, development and innovation: a contribution of the critical theory of technology to the discussion.

    PubMed

    Souza, Luis Eugenio Portela Fernandes de

    2016-11-03

    The relationships between health and socioeconomic development are diverse. These relationships find in the health economic complex a privileged ground for expression. The importance of health technologies increased exponentially since the middle of the 20th century, affecting health systems in terms of both, quality of care and economic aspects. In fact, the predominant model of care is based on fragmented, symptomatic therapy practices that encourages the use of products and services and promotes a passive participation of users rather than humanization of care. Overcoming this model requires changes in the health technology standards which, in turn, require changes in the technology standard of society. The critical theory of technology helps to understand the evolution of the industrial civilization. It enriches the discussion by suggesting the health economic complex be more sensibly adjusted to the requirements of comprehensive health care, and to inclusive and sustainable development. Resumo: As relações entre a saúde e o desenvolvimento socioeconômico são múltiplas. Essas relações têm o complexo econômico da saúde como o espaço privilegiado de sua expressão. A importância das tecnologias de saúde aumentou exponencialmente desde meados do século XX, com efeitos sobre os sistemas de saúde, tanto em qualidade da atenção, quanto em aspectos econômicos. Na realidade, predomina um modelo de atenção caracterizado por práticas fragmentadas, que enfatizam tratamentos sintomáticos, estimulam o consumismo de produtos e serviços e promovem, ao invés da humanização, uma participação passiva dos usuários. A superação desse modelo passa pela mudança do padrão tecnológico da saúde, que, por sua vez, exige a transformação do padrão tecnológico da sociedade. A teoria crítica da tecnologia ajuda a compreender a evolução da civilização industrial. Enriquece o debate, sugerindo uma conformação do complexo econômico da saúde mais

    Mora Polanco, Miguelena

    La ciencia es el eje fundamental a traves del cual se desarrollan las habilidades necesarias para el pensar cientifico que va a la busqueda del conocimiento cientifico. La intencion de este estudio fue indagar en el tema de investigacion cientifica desde el punto de vista de los participantes en los siguientes aspectos relacionados con la experiencia de investigacion cientifica: a) conceptos, b) proceso, c) destrezas y d) disposicion. Tambien se analizaron: a) las perspectivas del metodo cientifico, b) la estrategia de ensenanza, c) la cultura cientifica y d) la exposicion del proyecto investigativo en la Feria Cientifica; como parte del aprendizaje significativo de la ciencias de los participantes. Esta investigacion cualitativa propuso como diseno el estudio de caso. Los aspectos relacionados a la experiencia de participar en proyecto de investigacion cientifica son el fenomeno o caso bajo estudio. En el estudio participaron cinco (5) estudiantes egresados de escuela publica o privada que cursaban hasta el tercer ano de estudios universitarios, conducentes a un bachillerato en educacion secundaria en ciencias o en ciencias naturales. Las tecnicas utilizadas para recopilar los datos fueron: analisis de documentos del DEPR, revision de artefactos y entrevistas profundas. Para el analisis de los datos de las entrevistas se utilizo el modelo de Wolcott (1994). Del analisis de documentos del DEPR se identificaron areas a mejorar en las guias de las cartas circulares con relacion a la investigacion escolar y la feria cientifica. El analisis de los artefactos proveyo evidencia de como los internados, simposios e investigaciones fomentan el que los estudiantes se superen en el aspecto cognitivo, se conviertan en creadores del conocimiento, al hacer suyo los conceptos para poder explicarlos al publico. De las entrevistas los participantes manifestaron que la experiencia de investigacion fue una de aprendizaje significativo que los marco para toda la vida y les expandio su

    Introducción: Aunque los cambios en los patrones pueden ocurrir durante la gestación, predictores de estos cambios no han sido exploradas. Este estudio pretende identificar predictores de la adhesión a la dieta mediterránea (DM) desde el primer al segundo trimestre del embarazo. Metodología: Se realizó un estudio prospectivo con 102 embarazadas de edad 18-40, de la ciudad de Oporto, Portugal. Se evaluaron las características socio-demográficas y de estilo de vida a través de un cuestionario. Consumo de alimentos se evaluó con un diario de alimentos de tres días concluido durante los primeras y segundo trimestres. Los participantes fueron categorizados según su cambio en la adhesión a la DM en el cambio negativo (es decir, las mujeres que tenían poca adhesión en cada trimestre o tenido alta adhesión en el primer trimestre y luego baja adhesión en el segundo) y el grupo de cambio positivo (es decir, las mujeres que tenían alta adhesión en ambos trimestres o tenía baja adhesión en el primer trimestre y luego elevada adhesión en el segundo). Modelos de regresión logística stepwise condicional se realizaron para evaluar los posibles predictores de la variación negativa de DM. Resultados: Entre las 102 mujeres, 39,2% tenían cambio negativo del primer al segundo trimestre. Los resultados model´s logística muestran que estar casada (OR = 0,26, IC95%: 0,10, 0,76) y tener una mayor ingesta de verduras en el primer trimestre (OR = 0,17, IC95%: 0,10, 0,43) se asociaron con menor probabilidad de tener un cambio negativo en la adhesión a la DM del primer al segundo trimestre. Conclusiones: Estado civil y el consumo de vegetal parecen estar asociado con una menor ocurrencia de cambio negativo en la adhesión a la MD desde temprano a medio embarazo.

  11. Alfabetización en Astronomía de docentes de Educación Primaria y de Educación Secundaria en La Plata

    2014-10-01

    La educación de este siglo tiene como uno de sus retos alcanzar la alfabetización cientfica de todos los ciudadanos para que comprendan y tomen decisiones sobre el mundo natural y sus cambios originados por la actividad humana utilizando el conocimiento científico. En esta misión los docentes de los niveles obligatorios de enseñanza juegan un papel clave por su rol de agentes multiplicadores del conocimiento. Se requiere, entonces de una adecuada alfabetización en ciencias de los docentes o, como mínimo, que dominen los temas científicos a enseñar. En el campo de la Astronomía, numerosas investigaciones han señalado que maestros de primaria y estudiantes de profesorados poseen una escasa formación en estos temas (Camino 1995 y 1999, Gangui 2010), que frecuentemente presentan a los alumnos concepciones alternativas o no científicas de los fenómenos astronómicos cotidianos (Kriner 2004, Vega Navarro 2007, Gangui et al 2010); a lo que se suma la presentación confusa o errónea de algunos temas astronómicos en los textos escolares (Kriner 2004). Desde 2011, la Facultad de Ciencias Astronómicas y Geofísicas, UNLP, ofrece un curso de capacitación destinado a fortalecer y actualizar los contenidos académicos y didácticos de los docentes del distrito La Plata utilizando diversas estrategias didácticas. Los contenidos comprenden los temas astronómicos de los diseños curriculares vigentes. La evaluación diagnóstica de los conocimientos previos de los docentes cursantes sobre los contenidos de mayor presencia en los diseños curriculares mostró resultados similares a las investigaciones arriba mencionadas. Referente a los movimientos de la Tierra, en promedio, el 54% poseía conceptos erróneos y el 16% no los sabía; con referencia a la Luna el 56% poseía conceptos erróneos y un 4% no los sabía. Los resultados del curso mostraron que el 95% de los docentes revirtió sus conceptos previos erróneos, que adquirió criterios para la búsqueda de

  14. [Autisms that 'cure themselves'].

    PubMed

    Artigas-Pallares, J; Paula-Perez, I

    2016-01-01

    Introduccion. La investigacion sobre el autismo, basada principalmente en el modelo categorico del Manual diagnostico y estadistico de los trastornos mentales, se ha centrado de forma preferente en la epidemiologia, las manifestaciones clinicas, los mecanismos cognitivos y los determinantes biologicos y ambientales; sin embargo, se ha prestado escaso interes a las trayectorias evolutivas, las cuales son decisivas de cara al pronostico a medio y largo plazo. Objetivo. Revisar el curso evolutivo de niños diagnosticados de autismo que, aun conservando a medio o largo plazo rasgos conductuales acordes con el perfil inicial, alcanzan una adaptacion social y laboral satisfactorias, y ademas dejan de cumplir los criterios que dieron lugar al diagnostico inicial. Desarrollo. Se ha revisado la bibliografia sobre el autismo centrada en el analisis de la evolucion de las manifestaciones clinicas y de su repercusion desde las primeras edades hasta la edad adulta. Asimismo, se han tomado en consideracion aspectos conceptuales sobre el autismo que facilitan la comprension y el significado de los patrones evolutivos. Conclusiones. Alrededor del 20% de los niños diagnosticados dejan de cumplir los criterios en los que se baso el diagnostico y, ademas, alcanzan un ajuste social y laboral satisfactorio. Como factores favorecedores se identifica: inteligencia normal, buen nivel de lenguaje y baja incidencia de 'comorbilidades'; por el contrario, en las series notificadas no se señalan como factores determinantes las intervenciones terapeuticas precoces e intensivas. Por ultimo, se menciona el concepto de neurodiversidad, donde la recuperacion se centra en el desarrollo optimo de las capacidades de cada individuo en un entorno facilitador.

  15. Variabilidade óptica de longo período e precessão de jato: o caso de BL Lacertae

    NASA Astrophysics Data System (ADS)

    Caproni, A.; Abraham, Z.

    2003-08-01

    Variabilidade é tipicamente uma característica de AGNs, sendo observada em toda a faixa eletromagnética. Em relação às escalas de tempo, variações desde horas até de algumas décadas foram encontradas por vários autores. Em alguns casos, análises temporais de curvas de luz mostram a existência de periodicidade nas variações observadas. Um exemplo de objeto que preenche as características mencionadas acima é BL Lacertae, o protótipo da classe BL Lac dos AGNs. Neste trabalho, nós interpretamos a variabilidade periódica de longo período detectada na curva de luz na banda B (~7,5 anos) como o resultado da periodicidade na amplificação da radiação oriunda do jato relativístico. Neste cenário, a amplificação periódica seria induzida pela precessão, que muda o ângulo entre o jato e a linha de visada. Com esta abordagem e vínculos adicionais fornecidos por observações em altas energias, nós podemos impor limites para os parâmetros do modelo de precessão, tais como o fator de Lorentz associado ao movimento global do jato, o ângulo de abertura do cone de precessão e o ângulo entre o eixo do cone e a linha de visada.

    Introduccion. El ictus es una causa principal de mortalidad y discapacidad. El policosanol ha sido eficaz en modelos de isquemia cerebral. Este estudio investiga si el tratamiento a largo plazo con policosanol, añadido a la terapia con acido acetilsalicilico (AAS), dentro de los 30 dias posteriores a un ictus, es mejor que el placebo + AAS en la recuperacion de los pacientes. Pacientes y metodos. Estudio aleatorizado, doble ciego, controlado con placebo. Se incluyeron 80 pacientes (edad media: 69 años) que sufrieron un ictus en los 30 dias previos y con una puntuacion de 2-4 en la escala de Rankin modificada (mRS). Se distribuyeron aleatoriamente en dos grupos y recibieron policosanol + AAS o placebo + AAS durante 12 meses. Resultados. El tratamiento con policosanol + AAS disminuyo significativamente la puntuacion en la mRS desde el primer control intermedio (1,5 meses). El efecto del tratamiento incluso mejoro con la terapia a largo plazo. El numero de pacientes que alcanzaron valores de mRS menores o iguales a 1 fue superior en el grupo de policosanol + AAS (87,5%) que en el de placebo + AAS (0%). El tratamiento con policosanol + AAS aumento significativamente el indice de Barthel, disminuyo el colesterol LDL y aumento el colesterol HDL frente a placebo + AAS. Conclusiones. El tratamiento a largo plazo (12 meses) con policosanol + AAS fue mas efectivo que el tratamiento con placebo + AAS en la recuperacion funcional de los pacientes despues de sufrir un ictus isquemico no cardioembolico de moderada gravedad.

  17. Agregación de para-H2 en chorros supersónicos: del dímero al sólido

    María Fernández, José

    En este trabajo se mostrarán los estudios de expansiones supersónicas de para-H2 desde toberas criogénicas, realizados en el laboratorio de Fluidodinámica Molecular del IEM. Hemos registrado los espectros Raman de dichas expansiones en el intervalo de frecuencias de 4145 a 4162 cm-1, próximo a la línea Q(0) del monómero no rotante H2, a 4161.18 cm-1. En el espectro Raman, además de la línea Q(0) del monómero, se observan unos picos débiles, que, por su comportamiento con la temperatura de la tobera y la distancia a la misma, asignamos a la transición homóloga en agregados de p-H2. Dependiendo de las condiciones, se observan agregados pequeños (de 2 a 13 moléculas de p-H2), agregados medios y masivos, y se llega incluso al líquido y al sólido. Las asignaciones se apoyan en un modelo sencillo, basado en la perturbación, debida al potencial intermolecular, de los estados vibracionales v=0 y v=1 en los agregados de p-H2. Se mostrarán detalles de la instalación experimental, ejemplos de los espectros obtenidos en diversas condiciones, y detalles de la interpretación cuantitativa.

    In this work, 3-nitro-1H-1,2,4-triazole (1) and 3,5-dinitro-1H-pyrazole (2) were C-aminated and N-aminated using different amination agents, yielding their respective C-amino and N-amino products. All compounds were fully characterized by NMR (1H, 13C, 15N), IR spectroscopy, differential scanning calorimetry (DSC). X-ray crystallographic measurements were performed and delivered insight into structural characteristics as well as inter- and intramolecular interactions of the products. Their impact sensitivities were measured by using standard BAM fallhammer techniques and their explosive performances were computed using the EXPLO 5.05 program. A comparative study on the influence of those different amino substituents on the structural and energetic properties (such as density, stability, heat of formation, detonation performance) is presented. The results showed that the incorporation of an N-amino group into a nitroazole ring can improve nitrogen content, heat of formation and impact sensitivity, while the introduction of a C-amino group can enhance density, detonation velocity and pressure. The potential of N-amino and C-amino moieties for the design of next generation energetic materials is explored.

    Coelho, P.; Barbuy, B.; Melendez, J.; Allen, D. M.; Castilho, B.

    2003-08-01

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

    NASA Astrophysics Data System (ADS)

    Yáñez, M.

    Pocos campos de la química están tan bien adaptados a la modelización por medio de los métodos teóricos de la Química Cuántica como la Astroquímica y la Química de la Atmósfera, donde las interacciones moleculares son, generalmente, lo suficientemente pequeñas para que el modelo de molécula aislada funcione muy bien. En España son varios los grupos teóricos que dedican su esfuerzo de investigación, o parte de él, al estudio de moléculas o procesos de interés en Astrofísica o en atmósferas planetarias. Presentaremos diferentes ejemplos paradigmáticos de esta actividad en la que se exploran desde aspectos estructurales, hasta aspectos espectroscópicos y dinámicos. Entre los últimos, cabe destacar estudios en los que se demuestra la importancia de procesos a dos estados, prohibidos por espín, en la formación astrofísica de diversos derivados de interés. En el tratamiento espectroscópico se han hecho esfuerzos interesantes, que han aunado teoría y experimento, en el estudio de sistemas relevantes desde el punto de vista atmosférico, como los hidratos de ácido nítrico, o el tratamiento espectroscópico de moléculas no rígidas. No menos interesantes son los estudios de fotoabsorción de radicales o de procesos multifotónicos. Son particularmente abundantes los estudios dedicados a la reactividad específica de sistemas de interés astrofísico o atmosférico, con el objetivo de esclarecer vías de formación de determinados compuestos o de proporcionar mecanismos que permitan identificar las etapas reactivas limitantes de reacciones de interés en esos medios y sobre los que no existía información previa. Así, por ejemplo, se han publicado interesantes estudios sobre la formación o propiedades de compuestos de fósforo, de silico o de azufre o sobre mecanismos de reacción en los que intervienen el ozono, el radical nitrato, el radical OH u otras especies. Finalmente, son también particularmente relevantes los estudios que varios

    Objetivo: Se pretende evaluar la eficiencia del tratamiento secuencial de combinación de la hipertensión arterial pulmonar iniciado con antagonistas del receptor de la endotelina, ambrisentan o bosentan, seguido de inhibidores de la fosfodiesterasa- 5 y prostanoides, desde la perspectiva del Sistema Nacional de Salud. Métodos: Se desarrolló un modelo de Markov basado en las cuatro clases funcionales de la New York Heart Association. Un panel de tres expertos alcanzó un consenso sobre el manejo del paciente basado en la práctica clínica. Los pacientes revisaron su tratamiento cada 12 semanas, en función de su estado de salud y de la medicación recibida previamente. Se incluyeron costes farmacológicos y costes asociados al manejo de eventos adversos (EA) muy frecuentes, en un horizonte de 60 semanas. Los resultados se expresaron en términos de los años de vida ajustados por calidad (AVAC). Se realizó un análisis de sensibilidad probabilístico. Resultados: No se encontraron diferencias clínicamente relevantes en los AVAC por paciente y año para el inicio con ambrisentan y bosentan: 0,6853 y 0,6902, respectivamente. El inicio con ambrisentan resultó en un coste farmacológico y asociado al manejo de EA menor: 35.550 ??y 117 ??frente a 40.224 ??y 171 ?. En el análisis de sensibilidad, el inicio con ambrisentan presentó una diferencia de costes totales negativa y significativa: -4.982 ?; IC95%[-8.014 ?; -2.500 ?]; mientras que no se detectaron diferencias significativas en los AVAC: -0,0044; IC95%[-0,0189; 0,0101]. Conclusiones: El tratamiento secuencial de combinación de la HAP iniciado con ambrisentan, seguido de inhibidores de la fosfodiesterasa- 5 y prostanoides, proporciona resultados en salud comparables y menores costes que el tratamiento iniciado con bosentan.

    Introducción: la hidratación se define como el aporte de agua proveniente de alimentos y bebidas. Su estudio constituye desde hace unos años un área en sí misma dentro de la nutrición, que ha supuesto que en 2010 la European Food Safety Authority (EFSA) aprobara las recomendaciones de ingesta de agua; pero el estudio del estado de hidratación implica un elevado nivel metodológico que presenta ciertos desafíos. Objetivo: ofrecer una visión general de los principales problemas metodológicos en estudios sobre el estado de hidratación. Material y métodos: revisión de la bibliografía científica existente. Resultados: los principales problemas metodológicos presentes son: selección de la muestra (ámbito de investigación y diseño muestral), selección del método de evaluación del estado de hidratación (técnicas de dilución, impedancia bioeléctrica, indicadores plasmáticos y urinarios, cambios en la composición corporal, pérdidas de agua y síntomas clínicos), selección del método de valoración de la ingesta de agua (biomarcadores, cuestionarios, programas informáticos, uso de smartphones, registro 24 h, historia dietética y frecuencia de consumo de alimentos), así como sus principales fuentes dietéticas. Conclusiones: el estado de hidratación debe ser entendido como un modelo rutinario, de frecuencia diaria y variable en función de la edad, sexo, actividad física y condiciones ambientales; por todo ello es de especial importancia un correcto diseño metodológico capaz de recoger estos matices.

Para conocer los efectos del PD en una población sedentaria frente al ejercicio excéntrico, y como modelo del daño muscular inflamatorio. Metodología: Se llevó a cabo un estudio experimental, doble ciego, multigrupo, randomizado, con un grupo experimental (n = 17) al que se le administró una formulación de PD (3,6 g/sujeto distribuidos en 9 dosis de 400 mg desde el 3.er día pretest), y un grupo control (n = 16) que tomó sustancia placebo. Se realizaron dos ergoespirometrías en tapiz rodante a cada participante: una previa al estudio (protocolo de Bruce modificado) para descartar signos de isquemia durante el esfuerzo y valorar el VO2max; la segunda, aplicando un protocolo excéntrico (14% de desnivel descendente), durante 10 minutos en estado estable a una intensidad entre 70-80% del VO2max individual, como protocolo experimental. Se efectuaron comparaciones intragrupo e intergrupo del porcentaje de cambio pre-postesfuerzo en variables sanguíneas y de funcionalidad muscular. Resultados: El estudio evidencia aumentos significativos de enzimas musculares MG, CPK y LDH en los dos grupos de estudio, sin cambios para la TncI, siendo significativamente menores en el grupo al que se le administró PD. Se observaron reducciones significativas de los test funcionales SJ, CMJ en ambos grupos, lo que mostró un apreciable menor descenso en el grupo PD. Se apreció una reducción del índice elástico y de la dinamomentría manual solo en el grupo control, aunque las diferencias con el grupo PD no alcanzaron una significación estadística. Conclusiones: El protocolo del ejercicio excéntrico en el presente estudio ha inducido daños musculoesqueléticos y en la funcionalidad muscular, que han

  18. Reacciones de intercambio de carga

    NASA Astrophysics Data System (ADS)

    Errea, L. F.

    Se discute la validez de diversas metodologías y su aplicación al estudio de procesos de intercambio de carga electrónico entre iones y blancos atómicos y moleculares. Para energías de impacto entre 0.05 y 5 eV / amu se emplea el método cuántico de la Coordenada de Reacción Común (CRC). A mayores energías, se utiliza el método semiclásico iconal con un desarrollo de la función de onda dinámica en estados moleculares adiabáticos, modificados con un factor de traslación común (FTC). Estos estados pueden obtenerse con cálculos ab initio o empleando potenciales modelo. Cuando la ionización compite con la transferencia de carga, la inclusión de pseudoestados en estos desarrollos permite calcular simultáneamente las secciones eficaces de ambos procesos. Otra técnica utilizada es el método estadístico CTMC. En el tratamiento de colisiones ión-molécula (diatómica) contrastamos la aplicabilidad de distintos métodos, desde la llamada aproximación Franck-Condon hasta un desarrollo en estados vibrónicos, pasando por la aproximación súbita vibro-rotacional, obteniéndose secciones eficaces de captura electrónica total y a estados individuales, así como secciones de excitación vibracional a estados ligados y del continuo (disociación). En todos los casos es necesario calcular superficies de energía y los correspondientes acoplamientos dinámicos entre los estados. La aplicación de estos métodos permite determinar el grado de contaminación de los haces por estados metaestables en un experimento dado, el cambio en los resultados con diferentes isótopos, la importancia de procesos de doble captura, seguida de explosión culombiana, todo ello con precisión comparable a la de medidas experimentales, para sistemas de interés en distintos tipos de plasmas.

    The paper deals with the subject of the Four Seasons, exploring elements of Science and the Art in order to motivate students or public of museums of science and technology to understand it from their current cultural experiences and of old times. Physics joins to Astronomy to explain the phenomenon, while the use of Music and Painting make possible the immersion in the subject in way to many trips to the imagination capable to awake emotions.A proposal didactic is presented and justified for some consensus of the research in the area of teaching-learning of science, since that related to the persistent alternative conceptions concerning the causes of the changes observed at the different times of the year until the qualitative modelling of phenomena that appeals three-dimensional pedagogical models. Such proposal was developed in the activity named " Hiper interesting Talk: The Four Seasons, Science and Art" in the first Sunday of August/2003 in the Museum of Astronomy, MAST. O artigo trata do tema das Estações do Ano, explorando elementos da Ciência e da Arte como forma de motivar estudantes ou público de museus de ciência e tecnologia a compreendê-lo a partir de vivências culturais atuais e de outras épocas. A Física se junta à Astronomia para explicar o fenômeno, enquanto a Música e a Pintura possibilitam a imersão no tema em meio a muitas viagens à imaginação capazes de despertar emoções.Uma proposta didática é apresentada e justificada por consensos das muitas pesquisas na área de ensino-aprendizagem de ciências, desde os que se referem às persistentes concepções alternativas acerca das causas das mudanças observadas nas diferentes épocas do ano até à modelagem qualitativa de fenômenos que recorre a modelos pedagógicos tridimensionais. Tal proposta foi desenvolvida na atividade "Bate papo Hiperinteressante: As Quatro Estações, Ciência e Arte" realizada no primeiro domingo do mês de agosto de 2003 no Museu de Astronomia.

  20. Variación temporal de las constantes fundamentales

    NASA Astrophysics Data System (ADS)

    Landau, S. J.; Vucetich, H.

    La variación temporal de las constantes fundamentales es un problema que ha motivado numerosos trabajos teóricos y experimentales desde la hipótesis de los grandes números de Dirac en 1937. Entre los métodos experimentales y observacionales para establecer restricciones sobre la variación de las constantes fundamentes es importante mencionar: comparación entre relojes atómicos[1], métodos geofísicos[2][3], análisis de sistemas de absorción en quasares[4][5][6] y cotas provenientes de la nucleosíntesis primordial[7]. En un trabajo reciente[5], se reportó una significativa variación en la constante de estructura fina. Intentos de unificar las cuatro interacciones fundamentales dieron como resultado teorías con múltiples dimensiones como las teorías de Kaluza-Klein y teorías de supercuerdas. Estas teorías proporcionan un marco teórico natural para el estudio de la variación temporal de las constantes fundamentales. A su vez, un modelo sencillo para estudiar la variación de la constante de estructura fina, fue propuesto en [8], a partir de premisas muy generales como ser covarianza, invarianza de gauge, causalidad y invarianza ante reversiones temporales en el electromagnetismo. Diferentes versiones de las teorías antes mencionadas coinciden en predecir variaciones temporales de las constantes fundamentales pero difieren en la forma de esta variación[9][10]. De esta manera, las restricciones establecidas experimentalmente sobre la variación de las constantes fundamentales pueden ser una herramienta importante para testear estas diferentes teorías. En este trabajo, utilizamos las cotas provenientes de diversas técnicas experimentales, para testear si las mismas son consistentes con alguna de las teorías antes mencionadas. En particular, establecemos cotas sobre la variación de los parámentros libres de las diferentes teorías como por ejemplo el radio de las dimensiones extras en las teorías tipo Kaluza-Klein.

    Santos, S. C.; Chiaradia, A. P. M.

    2003-08-01

    O principal objetivo deste trabalho é auxiliar o professor de Geografia em sala de aula no ensino de tópicos relacionados com a Cosmologia. A idéia deste trabalho surgiu quando foi constatado que o professor de Geografia tem dificuldades de ensinar este tópico. Esta constatação foi feita por uma das autoras ao lecionar este tópico no ensino fundamental e em discussões com outros professores de Geografia. Da mesma maneira que ocorria desde os tempos mais antigos, os alunos têm muito interesse em conhecer os fenômenos que ocorrem no Cosmo, porém os livros didáticos de Geografia utilizados em sala de aula não são ricos em informações sobre este assunto. Assim, o professor de Geografia tem poucas informações para discutir este assunto em sala de aula e não dá a devida importância para este tópico. Então, foi desenvolvido um material de apoio para professores de Geografia sobre a origem do Universo, sua evolução e seu possível futuro evolutivo segundo as mais recentes teorias, com base em perguntas feitas pelos alunos de ensino fundamental e as informações trazidas nos livros didáticos Não cabe a este material inovar e tão pouco trazer uma metodologia de ensino de Cosmologia. Neste material o professor de Geografia pode encontrará um banco de informações, que constitui no estabelecimento de conceitos, teorias e hipóteses, sobre a Cosmologia, em linguagem simples e de fácil entendimento. Para desenvolvê-lo, foram feitas pesquisas não exaustivas em livros e revistas científicas, compilação e discussão em forma cronológica das teorias aceitas sobre modelos cosmológicos. Portanto, este material será apresentado neste trabalho.

  2. Extensión del Formalismo de Orbitales de Defecto Cuántico al tratamiento del efecto Stark (SQDO).

    NASA Astrophysics Data System (ADS)

    Menéndez, J. M.; Martín, I.; Velasco, A. M.

    El estudio experimental de las interacciones de átomos Rydberg altamente excitados con campos eléctricos ha experimentado un creciente interés durante las dos últimas décadas debido, en gran medida, al desarrollo de nuevas técnicas para crear y estudiar átomos Rydberg en el laboratorio. Acompañando a estas nuevas técnicas experimentales, es necesario el desarrollo de modelos teóricos que nos permitan contrastar sus medidas y conocer mejor los fundamentos de los mismos. Desde el punto de vista teórico el conocimiento del desdoblamiento de los niveles energéticos de un átomo en función de la magnitud del campo eléctrico aplicado (lo que se conoce como mapa Stark) es el mejor punto de partida para la descripción del sistema y un prerrequisito fundamental para el cálculo de distintas propiedades atómicas en presencia del campo eléctrico tales como intensidades de transición, umbrales de ionización de campo eléctrico, tiempos de vida, posición y anchura de cruces evitados, etc. En este trabajo presentamos la adaptación del método de orbitales de defecto cuántico [1,2,3] al tratamiento del efecto Stark (SQDO) [4] y su aplicación al cálculo de los desdoblamientos energéticos y fuerzas de oscilador de estados Rydberg en los átomos de Li, Na y K. El propósito de este estudio es, por un lado, desarrollar métodos fiables para la determinación de propiedades atómicas en presencia de campos eléctricos y, por otro, mostrar la fiabilidad de las funciones de onda QDO en la descripción del efecto Stark en sistemas atómicos.

    2015-04-01

    Introducción: existe una creciente evidencia científica de que la nutrición ejerce una influencia tanto positiva como negativa en la salud a lo largo de la vida. Diversos autores han destacado que la población universitaria es un grupo especialmente vulnerable desde el punto de vista nutricional ya que se caracteriza por omitir comidas con frecuencia y realizar pequeñas ingestas repetidas veces entre las comidas principales. Objetivo General: establecer la relación existente entre el número de ingestas alimentarias diarias (NIAD), el consumo de macronutrientes y el estado nutricional (EN) en estudiantes de 23-33 años de la Universidad Tecnológica Nacional (UTN), de la ciudad de Córdoba, en el año 2013. Métodos: se utilizó un diseño prospectivo de tipo descriptivo simple correlacional de corte transversal. Se realizó análisis descriptivo e inferencial mediante modelos de regresión logística múltiple. Resultados: de la muestra analizada casi un 50% presentó sobrepeso (SP) y un 40% grasa corporal (GC) elevada. En relación al número de ingestas, los estudiantes que realizaron menos de 4 y más de 6 ingestas tuvieron 2 veces más chance de presentar exceso de peso y de GC. A medida que aumenta la edad también lo hacen los depósitos de GC, y cuando disminuyen los niveles de actividad física (AF) aumenta la chance de presentar un índice de masa corporal (IMC) y GC elevada. Por otro lado, el consumo excesivo de glúcidos aumenta la chance de presentar GC elevada y SP, y el de proteínas y lípidos, el riesgo de GC elevada. Conclusión: Se reconoce al NIAD inferior o superior al recomendado, el bajo nivel de AF, el elevado consumo de carbohidratos, y la edad superior a 29 años como variables relacionados con el SP y la GC elevada.

  5. Modèle numérique de terrain comme outil pour contrôler et mesurer l'érosion de ravinsModelos digitales de elevación como un instrumento para seguir y medir erosión por cárcavas

    NASA Astrophysics Data System (ADS)

    Betts, Harley D.; DeRose, Ronald C.

    This paper describes the use of Digital Elevation Models (DEMs), constructed from sequential aerial photographs, as a tool for measuring gully erosion in a geomorphologically unstable environment. The technique is applied to a case study that examines erosion in 26 gullies in two study areas in the upper Waipaoa catchment, eastern North Island, New Zealand. Changes over two consecutive time periods, ranging in length from 14.0 years to 33.2 years, were studied at each site, drawing on available historical aerial photography. Several key aspects of the method used are described and discussed in detail, and recommendations are made for future application of DEMs for assessment of landscape change. DEM-measured gully degradation rates are directly proportional to the square root of the gully area.From this relationship it should be possible to rapidly estimate gully erosion at a catchment scale on the basis of gully areas alone. DEM-based measurement techniques, together with appropriate consideration for the sensitivity of the method, have significant cost and efficiency advantages over manual approaches to erosion measurements.

    One of the most important uses of SAR interferometry is in the generation of digital elevation models (DEMs). However, a standard procedure for quality estimation of DEMs does not exist. This paper proposes a method of quality estimation using an adapted Monte Carlo simulation, which has the advantage that it could be used in areas where appropriate reference DEMs are not available. This paper also addresses interferometric processing, with special emphasis on the influence of the input parameters. Practical implementation of the proposed technique is shown on a data set from Lower Saxony in Germany. The error map generated, which is a measure of the quality of the DEM, is also presented. For further analysis of the critical aspects of quality, a reference DEM has also been used.

La estimación de los flujos se ha hecho con base en los niveles y conductividades hidráulicas medidos en pozos, y en las tasas de evaporación medidas mediante una cámara de humedad. Contrariamente a los modelos conceptuales propuestos en estudios previos, se ha estimado que la entrada de agua subterránea es pequeña, mientras que las componentes principales del balance son la recarga de agua de lluvia y la evaporación desde el nivel freático. Las estimaciones hechas en un volumen de sabkha de 1 m de anchura por 10 km de longitud y 10 m de profundidad indican que alrededor de 1 m3/a de agua entra y sale por flujo subterráneo lateral, 40-50 m3/a lo hacen por recarga desde niveles inferiores, y 650 m3/a proceden de la recarga de agua de lluvia. Teniendo en cuenta la estimación del flujo de agua y solutos para la recarga desde los niveles inferiores, se calcula que entre 7 y 8 vol

    Research developed with 95 students of the 6th year of elementary education in a public school of Uberlândia, Minas Gerais. It was a continuous work from February to December 2013, which led the students to participate in activities of observation of the environment, specifically the sky, analyzing the changes occurred. We focused on the study of variations in temperature, rainfall, day length, variations in the size of the shadows and changes in the aspect of the Moon. Our focus of analysis targeted the discussion of the knowledge that these students had about the topics indicated and as they entered the stage during the implementation of the proposal. The results showed a limited perception that students have of their environment, however, lately expanded due to the undertaken activities, especially in relation to the Moon. Working with systematic measure procedures reveals the careful handling of data so that they become understandable to students, and working with the shadows points towards the students first understand how shadows are formed, and then apply this knowledge to Astronomy. Finally, we conclude that the lived process consisted of an initial step of a work that should be encouraged for the subsequent years of training of these students. Proyecto de investigación desarrollado con 95 alumnos del sexto año de primaria en una escuela pública de Uberlândia, Minas Gerais. Fue un trabajo continuo, de febrero a diciembre de 2013, que llevó a los estudiantes a participar en actividades de observación de su entorno, entre ellas, el cielo, analizando los cambios ocurridos. Nos centramos en el estudio de las variaciones en la temperatura, las precipitaciones, la duración del día, las variaciones en el tamaño de las sombras y los cambios en los aspectos de la Luna. Nuestro foco de análisis se centró en discutir el conocimiento que estos estudiantes tenían sobre los temas indicados al inicio y término de la propuesta. Los resultados mostraron una percepción limitada que los estudiantes tienen de su alrededor la cual, sin embargo, se expandió debido a las actividades llevadas a cabo, sobre todo en relación con la Luna. Trabajar con medidas sistemáticas revela el manejo cuidadoso de los datos para que sean comprensibles para los estudiantes, así como el trabajo con las sombras para que comprendan primero como se forman estas para después trabajarlas en Astronomía. Por último, llegamos a la conclusión de que el proceso desarrollado consistió en una etapa inicial de una obra que debe ser profundizado en los años posteriores de la formación de estos estudiantes. Projeto de pesquisa desenvolvido com 95 alunos do 6º ano do Ensino Fundamental de uma escola pública estadual de Uberlândia, Minas Gerais. Foi um trabalho contínuo, de fevereiro a dezembro de 2013, o qual levou os alunos a participarem de atividades de observação do entorno, dentre ele, o céu, analisando as mudanças ocorridas. Focamos no estudo das variações de temperaturas, chuvas, duração do dia, variações do tamanho das sombras e mudanças nos aspectos da Lua. Nosso foco de análise centrou-se em discutir os conhecimentos que os referidos alunos tinham acerca dos temas indicados no início e ao término da implementação da proposta. Os resultados mostraram a percepção limitada que os estudantes possuem de seu entorno, todavia, ampliada em função das atividades desenvolvidas, principalmente no que se refere à Lua. O trabalho com medidas sistemáticas revela o cuidado no tratamento dos dados para que eles se tornem compreensíveis aos alunos, assim como o trabalho com as sombras sinaliza para que os alunos primeiramente compreendam como as sombras são formadas para depois trabalhar isso em Astronomia. Por fim, concluímos que o processo vivido constituiu-se em uma etapa inicial de um trabalho que deve ser estimulado para os anos subsequentes da formação desses alunos.

    Los conservacionistas cada vez más se comprometen con el concepto del bienestar humano para mejorar el diseño y la evaluación de sus intervenciones. Desde la convención de la influyente Comisión Sarkozy en 2009, los investigadores del desarrollo han estado refinando las conceptualizaciones y los marcos de trabajo para entender y medir el bienestar humano y están comenzando a convergir con un entendimiento común de cuál es la mejor forma de hacer esto. En la conservación el término bienestar humano tiene un uso amplio, pero existe la necesidad de la orientación en su operación para medir los impactos de las intervenciones de la conservación sobre la gente. Presentamos un marco de trabajo para entender el bienestar humano que podría ser útil particularmente en la conservación. El marco de trabajo incluye tres condiciones: cumplir con las necesidades, perseguir objetivos y experimentar una calidad satisfactoria de vida. Resumimos algunas de las complejidades involucradas en la evaluación de los efectos del bienestar de las intervenciones de la conservación con el entendimiento de que el bienestar varía entre la gente, en el tiempo y con las prioridades del evaluador. Los retos clave para la investigación de los impactos del bienestar de las intervenciones de la conservación incluyen la necesidad de crear una colección de estudios de caso para trazar lecciones generalizables: hacer uso del potencial de la tecnología moderna para apoyar la investigación del bienestar; y contextualizar espacial y temporalmente las evaluaciones de los impactos de la conservación sobre el bienestar dentro del marco más amplio del cambio social. Existen caminos que atraviesan la confusión que rodea al término bienestar, y los marcos de trabajo existentes, como el del acercamiento de Bienestar en Países en Desarrollo, pueden ayudar a los conservacionistas a negociar los obstáculos de la operación del concepto.

    Merchán Bonete, M.

    Estamos entrando en una era donde la ortogonalidad entre las investigaciones de carácter experimental y de naturaleza teórica se irá difuminando progresivamente y la problemática a resolver quedará en escena como el único actor principal de la obra. Como premisa para una cooperación teórico-experimental de igual a igual, la metodología químico-cuántica utilizada debe ser capaz de ofrecer resultados de carácter predictivo. Sin duda, esta madurez en la metodología químico-cuántica ya la hemos alcanzado hace algunos años, tal y como muestra entre otras muchas, la labor que nuestro grupo ha realizado en el transcurso de la última década, dentro del campo de la Espectroscopía Teórica. Los estudios realizados comprenden una amplia gama de sistemas, variando tanto en tamaño como en complejidad, abordando problemáticas espectroscópicas consideradas tradicionalmente como especialmente controvertidas. Nuestra contribución científica más relevante reside en el carácter cuantitativo de las asignaciones espectroscópicas que hemos propuesto en base a resultados ab initio. Recordemos que en los años noventa los resultados ab initio solían presentar para las energías de excitación de sistemas de tamaño molecular moderado, como el benceno, errores de más de 1 eV. En comparación con el éxito relativo de los métodos semiempíricos, la frustración de la metodología ab initio quedaba todavía más patente. Los estudios que hemos presentado representan una comprensión profunda de los espectros electrónicos en sistemas orgánicos claves, mostrando el camino a seguir para obtener asignaciones espectroscópicas precisas (entre 0.1-0.2 eV). La naturaleza del método CASPT2 junto al diseño de estrategias computacionales nos ha permitido alcanzar el carácter cuantitativo con el que se caracterizan nuestras contribuciones[1,2]. Por todo ello, algunos de los trabajos publicados se consideran clásicos dentro del campo, pues en cierto modo definen el

  19. Alternate radiolabeled markers for detecting metabolic activity of Mycobacterium leprae residing in murine macrophages

    SciTech Connect

    Prasad, H.K.; Hastings, R.C.

    1985-05-01

    This study demonstrated the utility of using 4% NaOH as a murine macrophage cell-solubilizing agent to discriminate between host macrophage metabolism and that of intracellular Mycobacterium leprae. A 4% concentration of NaOH had no deleterious effect on labeled mycobacteria. Thereby, alternate radiolabeled indicators of the metabolic activity of intracellular M. leprae could be experimented with. Significant incorporation of /sup 14/C-amino acid mixture, (/sup 14/C)leucine, (/sup 14/C)uridine, and carrier-free /sup 32/P was observed in cultures containing freshly extracted (''live'') strains of M. leprae as compared with control cultures containing autoclaved bacilli.

    The uptake of a specific 14C-amino acid by the heterotrophic microorganisms in the epilimnion of an eutrophic lake was influenced by the presence of other amino acids. The effect of unlabeled serine on 14C-glycine uptake was shown to be caused by competitive inhibition, which changed the interpretation of the kinetic parameters, the turnover time, Tt, and the sum of a transport constant, (Kt + (Sn), and the natural substrate concentration. The maximum velocity of uptake, Vmax, is unaffected by the competitive inhibition. PMID:4687063

The following databases were used to research clinical trials and observational studies: Medline, Embase and Cochrane, from 2005 to 2015. when the Return of Spontaneous Circulation (ROSC) with administration of epinephrine was compared with ROSC without administration, increased rates were found with administration (OR 2.02. 95% CI 1.49 to 2.75; I2 = 95%). Meta-analysis showed an increase in survival to discharge or 30 days after administration of epinephrine (OR 1.23; 95% IC 1.05-1.44; I2=83%). Stratification by shockable and non-shockable rhythms showed an increase in survival for non-shockable rhythm (OR 1.52; 95% IC 1.29-1.78; I2=42%). When compared with delayed administration, the administration of epinephrine within 10 minutes showed an increased survival rate (OR 2.03; 95% IC 1.77-2.32; I2=0%). administration of epinephrine appears to increase the rate of ROSC, but when compared with other therapies, no positive effect was found on survival rates of patients with favorable neurological status. avaliar a efetividade da adrenalina na parada cardíaca e seu efeito na sobrevivência e no estado neurológico. revisão sistemática da literatura científica com meta-análise utilizando um modelo de efeitos aleatórios.

    relacionadas al mal tiempo. El problema de no tener suficientes actividades prácticas, la sensación de poseer conocimientos inadecuados, la necesidad de disponer de equipamiento astronómico y experiencia suelen ser demasiado intimidantes para que los profesores introduzcan la materia en sus clases. Si la Astronomía iba a ser introducida, entonces era preciso encontrar una forma de resolver estas dificultades. Nuestro grupo, trabajando con maestros y alumnos dentro de un marco constructivista, encontró que los principios de la Astronomía pueden ser descubiertos durante el día, en cuanto los alumnos están en la escuela. Trabajando de forma cooperativa los alumnos midieron y registraron observaciones de sus propias sombras causadas por los movimientos de la estrella más próxima, el Sol, y nuestro planeta Tierra. Debido a que los alumnos se involucraran tan personalmente en las actividades, estuvieron mucho más interesados en los resultados del estudio. La Astronomía pasó a ser un desafío para el maestro y sus alumnos cuando aplicaron sus experiencias diurnas a la observación nocturna desde sus casas, reportada después en clase. Estas atividades astronômicas diurnas surgiram de uma investigação feita na Nova Zelândia por um grupo de professores e astrônomos a respeito dos problemas do ensino da Astronomia. Este trabalho mostrou que a Astronomia é geralmente considerada uma disciplina difícil de ensinar, tradicionalmente baseada em livros, filmes e modelos. Os mais afortunados podem ter feito alguma visita a um observatório ou planetário, e os mais avançados podem talvez ter tentado uma sessão de observação noturna, as quais sofrem às vezes de dificuldades relacionadas ao tempo. O problema de não dispor de suficientes atividades práticas, a sensação de possuir conhecimentos inadequados, a necessidade de dispor de equipamento astronômico e experiência tem sido, em geral, demasiado intimidante para que os professores introduzam a matéria nas suas

    utilizando um dispositivo intragástrico de portal único em modelo experimental de suínos. Foram realizados 20 experimentos utilizando estômagos de cadáver de porco fresco em um instrutor laparoscópico. O procedimento foi realizado da seguinte forma em dez porcos: 1) medida de volume; 2) insuflação do estômago com CO2; 3) extroversão do estômago através do simulador e instalação do dispositivo de uma única via (Gelpoint Applied Mini) através de uma gastrotomia próxima ao piloro; 4) realização de quatro suturas de quatro pontos intra-gástricas com Prolene 2-0, desde o fundo gástrico até o antro; 5) medição do volume residual. A gastrectomia vertical foi também realizada em mais dez suínos e o volume gástrico pré e pós-procedimento foi medido. A técnica de plicatura gástrica interna foi realizada com sucesso nos dez experimentos com suínos. O tempo médio do procedimento foi de 27±4 min. Produziu redução do volume gástrico em média de 51%, e a gastrectomia vertical em média de 90% neste modelo suíno. A técnica de plicatura gástrica interna, utilizando um dispositivo intragástrico de uma única via, exigiu poucas habilidades para ser realizada, teve baixo tempo operatório e obteve boa redução (51%) do volume gástrico em um modelo experimental in vitro.

    Introduccion. Dado el aumento de prevalencia respecto a los diagnosticos de autismo en los ultimos años, la creciente investigacion sobre modelos para trabajar con las personas con trastornos del espectro autista (TEA) hace que se encuentren diversas tecnicas y metodos para obtener mayores resultados y poder asi ayudar a mejorar muchos de los sintomas que impiden llevar una vida plena a personas con dicho diagnostico y a sus familias. Objetivo. Revisar dos modelos de intervencion diseñados especificamente para trabajar con personas con TEA. Desarrollo. Se revisa el modelo de intervencion temprana Early Start Denver Model, que presenta un checklist para niños con TEA de 12 a 48 meses, a partir de la evolucion de estos. Se revisa tambien el modelo SCERTS. A diferencia del Denver, este modelo presenta objetivos a trabajar a lo largo de toda la vida de las personas con TEA. Conclusiones. A falta de mayores resultados de la practica basada en la evidencia cientifica respecto a los dos modelos revisados, se concluye que no existe un modelo unico estandarizado y que se necesita una derivacion precoz en niños con dificultades en atencion conjunta e imitacion y el trabajo junto con las familias. Asi pues, para realizar una correcta intervencion debe tenerse en cuenta tanto la practica basada en la evidencia como un conocimiento, respeto y comprension profunda de los niños con TEA y de sus familias por parte del terapeuta.

El Grano de los Datos de Costo Económico con Referencia Espacial y de Beneficio a la Biodiversidad y la Efectividad de una Estrategia de Determinación de Costos Resumen Entre 1990 y 2007, en promedio fueron cazados ilegalmente cada año 15 rinocerontes sureños blancos (Ceratotherium simum simum) y negros (Diceros bicornis) en Sudáfrica. Desde 2007 la caza ilegal de rinocerontes sureños blancos por su cuerno ha escalado a más de 950 individuos al año en 2013. Llevamos a cabo un análisis ecológico-económico para determinar si el comercio legal de cuerno de rinoceronte sureño blanco podría facilitar la protección del rinoceronte. Se usaron modelos lineales generalizados para examinar a los conductores socio-económicos de la caza furtiva, con base en datos colectados desde 1990 hasta 2013, y también para proyectar el número total de rinocerontes con probabilidad de ser cazados ilegalmente desde 2014 hasta 2023. Las dinámicas poblacionales de los rinocerontes fueron entonces modeladas bajo ocho escenarios políticos diferentes que podrían implementarse para controlar la caza furtiva. También estimamos los costos económicos y los beneficios de cada escenario solamente bajo la ejecución aumentada del plan de manejo y el comercio legal de cuerno de rinoceronte y usamos un marco de trabajo de apoyo a decisiones para ordenar los escenarios con el objetivo de mantener la población de rinocerontes por encima de su tamaño actual mientras se generan ganancias para los accionistas locales. Se predijo que la población de rinocerontes sureños blancos se extinguiría en menos de 20 años bajo el manejo actual. El escenario óptimo para mantener la población de rinocerontes por encima de su tamaño actual fue el de proporcionar un incremento mediano en el esfuerzo contra la caza furtiva e incrementar la multa monetaria de la condena. Sin legalizar el mercado, implementar tal escenario requeriría cubrir costos de aproximadamente $147, 000, 000 al año. Con

    Morphological changes in the venom gland of V. ammodytes were studied after the removal of the venom from the gland lumina (milking) It was found that the height of the secretory cells was changed during the secretory cycle. The patterns of the rough endoplasmic reticulum and of the Golgi complex were changed as well Milking induced an increased incorporation of [14C]amino acids into total and venom proteins In V ammodytes, during the first day after milking, 25% of the total counts in protein were precipitable by anti-venom serum, while at 8 days, 80% of the proteins synthesized were venom proteins At this stage, the incorporation was 10- and 20-fold that of unmilked glands for total and venom proteins, respectively. Venom was accumulated (secreted) in the gland lumina of V. ammodytes at a relatively high rate up to 2 wk after milking and leveled off afterwards. Intact glands and gland slices of V ammodytes and V palaestinae, taken from snakes a few days after milking, incorporated [14C]amino acids into proteins in vitro at a rate higher than that of unmilked glands. The activity of two exportable enzymes (phosphodiesterase and benzoyl arginyl ethyl esterase) was assayed in gland homogenates of V. ammodytes. It was found that 2–3 wk after milking, the intracellular level of these enzymes was up to 2-fold that of unmilked glands. PMID:4345163

    The pepino (Solanum muricatum) is an edible and juicy fruit native to the Andean region which is becoming increasingly important. However, little information is available on its phenolic composition and bioactive properties. Four pepino varieties (37-A, El Camino, Puzol, and Valencia) and one accession (E-7) of its close wild relative S. caripense were characterized by HPLC-DAD-MSn/ESI. Twenty-four hydroxycinnamic acid derivatives were detected (5 to 16 compounds per variety or accession), with differences of more than two-fold for their total content among the materials studied. The major phenolics in the pepino varieties were chlorogenic acids and derivatives, while in S. caripense a caffeoyl-synapoyl-quinic acid was the major compound. The in vitro antioxidant capacity (DPPH (2,2-diphenyl-1-picrylhydrazyl hydrate), ORAC (oxygen radical absorbance capacity), and TRC (total reducing capacity) tests) was higher in S. caripense. Pepino and S. caripense extracts were not toxic for RAW 264.7 macrophage cells, and the raw extracts inhibited NO production of the lipopolysaccharide (LPS)-stimulated macrophages by 36% (El Camino) to 67% (37-A). No single variety ranked high simultaneously for hydroxycinnamic acids content, antioxidant activity and biological activity. We suggest the screening of large collections of germplasm or the use of complementary crosses between Puzol (high for hydroxycinnamic acids and biological activity) and S. caripense E-7 (high for antioxidant activity) to select and breed pepino varieties with enhanced properties.

    To assess the utilization of an electronic medical record (EMR), the degree of satisfaction with this tool, as well as to detect problems in its utilization, in a tertiary hospital in Spain. A survey was sent by mail to all physicians in the Virgen del Camino Hospital in Pamplona, Spain. Out of 445 staff physicians, 174 answered the survey (39%). Seventy-nine percent considered that the EMR is better than the traditional, paper-based medical record. Sixty-one percent used the EMR for consultation and to introduce clinical data in a regular way. Fifty-five percent agreed that the EMR has advantages for the patient. The main problems detected are a loss in confidentiality, lack of time, insufficient number of computers, and inadequate training. Ninety percent answered that EMR implementation should be continued and only 6% are dissatisfied with the computer application. There is a high degree of utilization of the EMR in the Virgen del Camino Hospital. Measures should be implemented to resolve the problems detected in this survey.

  19. Model determination in a case of heterogeneity of variance using sampling techniques.

    1997-01-12

    A sampling determination procedure has been described in a case of heterogeneity of variance. The procedure makes use of the predictive distributions of each data given the rest of the data and the structure of the assumed model. The computation of these predictive distributions is carried out using a Gibbs Sampling procedure. The final criterion to compare between models is the Mean Square Error between the expectation of predictive distributions and real data. The procedure has been applied to a data set of weight at 210 days in the Spanish Pirenaica beef cattle breed. Three proposed models have been compared: (a) Single Trait Animal Model; (b) Heterogeneous Variance Animal Model; and (c) Multiple Trait Animal Model. After applying the procedure, the most adjusted model was the Heterogeneous Variance Animal Model. This result is probably due to a compromise between the complexity of the model and the amount of available information. The estimated heritabilities under the preferred model have been 0.489 ± 0.076 for males and 0.331 ± 0.082 for females. RESUMEN: Contraste de modelos en un caso de heterogeneidad de varianzas usando métodos de muestreo Se ha descrito un método de contraste de modelos mediante técnicas de muestreo en un caso de heterogeneidad de varianza entre sexos. El procedimiento utiliza las distribucviones predictivas de cada dato, dado el resto de datos y la estructura del modelo. El criterio para coparar modelos es el error cuadrático medio entre la esperanza de las distribuciones predictivas y los datos reales. El procedimiento se ha aplicado en datos de peso a los 210 días en la raza bovina Pirenaica. Se han propuesto tres posibles modelos: (a) Modelo Animal Unicaracter; (b) Modelo Animal con Varianzas Heterogéneas; (c) Modelo Animal Multicaracter. El modelo mejor ajustado fue el Modelo Animal con Varianzas Heterogéneas. Este resultado es probablemente debido a un compromiso entre la complejidad del modelo y la cantidad de datos

    Introducción y objetivo: Conocer y analizar la experiencia autorreferida del tratamiento de los pacientes VHC que iniciaron tratamiento con agentes antivirales directos (AAD), a tiempo real, de forma proactiva e integrada en el proceso asistencial de atención farmacéutica. Material y métodos: Estudio observacional y transversal desarrollado entre abril (inicio del Plan Estratégico Nacional) y diciembre de 2015 en la Consulta Externa del Servicio de Farmacia. Se utilizó como herramienta un cuestionario prospectivo cumplimentado por los pacientes donde se recogieron variables relacionadas con la calidad de vida vinculadas con la salud (CVRS), adherencia, efectos adversos (EA), satisfacción con el tratamiento, y valoración y utilidad del programa formativo implementado por el Servicio de Farmacia. Se realizó un análisis descriptivo de todas las variables incluidas en el estudio y se analizó la influencia de las diferentes variables en el grado de adherencia y CVRS. El análisis de las diferencias entre los dos grupos se realizó mediante el test de chi cuadrado y el cálculo de las OR con un modelo de regresión logística simple. Se utilizó el programa SPSS® versión 20, y se estableció una significación estadística para valores de p < 0,05. Resultados: Se recogieron155 encuestas de las 226 enviadas, tasa de respuesta del 68,6%.En referencia a la CVRS (valoración del estado físico y emocional), un 38,7% de los pacientes refieren que su estado físico y emocional es mucho mejor desde el inicio del tratamiento. La presencia de EA y una peor información global de su enfermedad se asoció con un peor estado físico y emocional (p < 0,05). La adherencia reportada fue del 84,5% y el tratamiento fue valorado como muy bueno o bueno por el 87% de los pacientes. Un 52,9% de los pacientes no tuvieron efectos adversos relacionados con la medicación y el proceso formativo realizado por el farmacéutico especialista en la primera consulta fue valorado por el 96

    ndices 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.

    Identifying the predictors of hope in patients with breast cancer during chemotherapy treatment. A prospective longitudinal study. The sample was composed of 122 women who responded to the instruments of hope, anxiety and depression, coping, fatigue, religiosity and self-esteem in the first and last cycle of chemotherapy. These variables were used in adjusting the logistic regression model that characterized multivariate statistics, allowing identification of predictor variables. The increase of hope at the end of chemotherapy treatment was statistically significant (p = 0.012). The delay in undergoing treatment from the onset of breast cancer symptoms, Karnofsky Performance Status, depression, self-esteem and pain were characterized as factors being associated to hope by univariate analysis. Among the variables analyzed, pain was the only predicting factor of hope. Pain was the predicting factor in this sample. Hope increased during treatment and revealed the following associated factors: Karnofsky Performance Status, delay in starting the treatment, depression, self-esteem and pain. This study brought forth a multidisciplinary contribution, allowing for understanding the factors that can influence hope and presenting support to nursing care. The data evidenced conditions of improvement or worsening of hope, which requires interdisciplinary attention in Oncology.

O resultado deste modelo de ensino, ao longo dos anos, é conhecido por todos: desconhecimento e descontentamento, por parte dos estudantes, de temas relativos ao papel e aos processos da ciência. Acreditamos que a Astronomia, pelo seu caráter observacional, é uma das áreas do conhecimento que pode contribuir neste cenário. A Fundação Planetário da Cidade do Rio de Janeiro possui um telescópio Meade LX-200 (25cm) que, juntamente com as câmeras CCD ST-7E e ST8E, tem sido utilizado em projetos voltados aos estudantes do ensino médio desde o ano 2000. Tais projetos envolvem a condução de um projeto de pesquisa observacional num nível apropriado, e possibilitam o contato com técnicas e novas tecnologias: computador, software para manipulação de dados e gráficos, programas de tratamento e redução de dados, uso de equipamentos óptico-eletrônicos (telescópio e CCD), bem como o processo de aquisição de conhecimento. Dentro da proposta dos anos anteriores, priorizamos projetos de uma noite, ou seja, procuramos trabalhar com fenômenos que apresentem variabilidade com intervalo de recorrência relativamente curto. Em todos os casos, optamos pela fotometria diferencial, que tem se mostrado bastante eficiente para o céu luminoso como o da cidade do Rio de Janeiro. Neste painel, apresentamos alguns dos projetos desenvolvidos no último ano, com 25 estudantes. Apresentamos os resultados da observação da variável pulsante AI Vel (V = 6,6) e da variável cataclísmica FO Aqr (V = 13,5), e do monitoramento do trânsito da lua de Júpiter, Europa, ocorrido em 30 de abril de 2003.

    The objective of this study is to analyze the frequency and factors associated with falls in adults aged 55 years or more. This is a study inserted into another population-based study with representative sample of persons aged 40 years or more of the urban area in a medium-sized municipality of the State of Paraná, Brazil, in 2011. That study obtained demographic and socioeconomic data and characteristics related to life habits, health conditions, and functional capacity (n = 1,180). In 2012, we selected all persons aged 55 years or more (n = 501). We have estimated grip strength and the occurrence of a fall since the last interview in 80.6% of the adults. The crude and adjusted odds ratios (OR) have been calculated by logistic regression according to a hierarchical model. The rate of fall was 24.3%. After adjustments, we could observe higher chances of falls among women (OR = 3.10; 95%CI 1.79-5.38), among persons aged 65 years or more (OR = 2.39; 95%CI 1.45-3.95), with poor sleep quality (OR = 1.78; 95%CI 1.08-2.93), and with low grip strength (OR = 2.31; 95%CI 1.34-3.97). Poor sleep quality and low muscle strength can be indicators of increased risk of falls and need assessments and interventions aimed at preventing them.

    To investigate the effects of oral zinc supplementation on fatigue intensity and quality of life of patients during chemotherapy for colorectal cancer. A prospective, randomized, double-blinded, placebo-controlled study was conducted with 24 patients on chemotherapy for colorectal adenocarcinoma in a tertiary care public hospital. The study patients received zinc capsules 35mg (Zinc Group, n=10) or placebo (Placebo Group, n=14) orally, twice daily (70mg/day), for 16 weeks, from the immediate postoperative period to the fourth chemotherapy cycle. Approximately 45 days after surgical resection of the tumor, all patients received a chemotherapeutic regimen. Before each of the four cycles of chemotherapy, the Functional Assessment of Chronic Illness Therapy-Fatigue scale was completed. We used a linear mixed model for longitudinal data for statistical analysis. The scores of quality of life and fatigue questionnaires were similar between the groups during the chemotherapy cycles. The Placebo Group presented worsening of quality of life and increased fatigue between the first and fourth cycles of chemotherapy, but there were no changes in the scores of quality of life or fatigue in the Zinc Group. Zinc supplementation prevented fatigue and maintained quality of life of patients with colorectal cancer on chemotherapy.

De los 19, 207 artículos publicados, 1, 667 (8.68%) están libres para descargar de un repositorio oficial. Además, sólo 938 artículos (4.88%) cumplen con la definición estándar de acceso abierto en la cual el material puede reutilizarse libremente siempre y cuando se le dé atribución a los autores. Esto se compara pobremente con un conjunto comparable de 20 revistas de biología evolutiva, donde 31.93% de los artículos están libres para descargar y el 7.94% son de acceso abierto. Diecisiete de las 20 revistas de conservación ofrecen una opción de acceso abierto, pero menos del 5% de los artículos están disponibles por medio del acceso abierto. El costo de acceder al cuerpo completo de la ciencia de la conservación llega a estar entre los miles de dólares por año para suscriptores institucionales, y muchos practicantes de la conservación no pueden acceder a la ciencia de paga en sus lugares de trabajo. Sin embargo, iniciativas importantes como Research4Life están poniendo a la ciencia a disponibilidad de organizaciones en países en desarrollo. Urgimos a los autores de la ciencia de la conservación que paguen por acceso abierto en una base por artículo o que escojan publicar en revistas de acceso abierto, tomando en consideración asegurar que la licencia permita reutilizar siempre y cuando se proporcione atribución.

Concernant les aquifères volcaniques, la transmissivité a également été estimée à l'aide d'une relation empirique reliant la transmissivité et le débit spécifique corrigé des pertes de charge anormales. La transmissivité pour chaque aquifère couvre jusqu'à quatre ordres de grandeur, montrant la forte hétérogénéité de ces milieux. Pour les roches volcaniques, on observe que la transmissivité est d'autant meilleure que la roche est plus jeune. Leur transmissivité a ainsi diminué durant les temps géologiques. La compréhension des propriétés hydrauliques de ces aquifères complexes est à présent bien meilleure, ce qui permet d'envisager une gestion optimale de leurs ressources à l'aide de modèles numériques. La República de Yibuti (23.000 km2, 500.000 habitantes) está situada en el Cuerno de África, donde se han formado diversas unidades volcánicas-basaltos y riolitas-y rocas sedimentarias desde la expansión de los continentes acaecida al inicio de la deriva continental (hace 30 millones de años). La precipitación media anual es inferior a 150 mm. Las rocas volcánicas y sedimentarias, con dimensión inferior a 2.000 km2, constituyen acuíferos locales. Los basaltos estratificados forman un acuífero regional que se extiende a más de 9.000 km2. La multitud de datos existente ha sido almacenada desde los años 1960 en una base de datos. La transmisividad de estos acuíferos ha sido determinada mediante datos de ensayos de bombeo y una relación empírica que usa la capacidad específica corregida con las pérdidas turbulentas en el pozo. La transmisividad de estos acuíferos se comporta como una variable lognormal, hecho importante para los trabajos previstos de modelación con métodos estadísticos. La transmisividad de cada acuífero puede variar hasta en cuatro órdenes de magnitud, manifestando su gran heterogeneidad. Para los materiales volcánicos, la transmisividad es mayor cuanto más joven es

    , um novo marcador de aterosclerose, pode contribuir para este risco. Apesar de associada a aumento de mortalidade na população geral, a avaliação de tal disfunção ainda não foi realizada de modo amplo em pacientes em hemodiálise. Neste estudo transversal, pacientes em hemodiálise foram submetidos à avaliação da vasodilatação mediada por fluxo, razão de viabilidade subendocárdica (RVSE) e índice de duração de ejeção, como estimativas de avaliação dos marcadores de DMO sobre disfunção vascular. Uma coorte pareada com (n = 16) e sem (n = 11) hiperparatireoidismo secundário (HPTS) grave foi estudada. Adicionalmente, o tempo transcorrido do diagnóstico de HPTS grave também foi avaliado. Pacientes com HPTS grave apresentaram menores valores de RVSE e maiores valores de índice de duração de ejeção, apontando maior risco cardiovascular. Baixa RVSE também foi associada à pressão arterial diastólica (r = 0,435, p = 0,049), níveis séricos de 25-Vitamina D (r = 0,479, p = 0,028) e maior tempo transcorrido desde diagnóstico de HPTS grave, definido como tempo em que o paciente permaneceu com valores de paratormônio superiores a 500 pg/ml até realização de cirurgia de paratireoidectomia ou término do estudo (r = -0,642, p = 0,027). Em regressão logística stepwise entre RVSE e variáveis independentes, menor RVSE foi independentemente associado a menores valores de 25-Vitamina D (p = 0,005), sexo feminino (p = 0,012) e maior tempo transcorrido desde diagnóstico de HPTS grave (p = 0,001) em um modelo ajustado para idade, colesterol sérico e pressão arterial (r2 ajustado = 0,545, p = 0,001). A perfusão subendocárdica foi menor em pacientes com DMO, refletindo o maior risco cardiovascular nesta população. Investigações adicionais são necessárias para definir se a paratireoidectomia precoce no curso da doença renal crônica poderia interferir neste risco.

La combinaison entre une concentration élevée en matières organiques, provenant de la recharge par les eaux usées domestiques, et la faible profondeur de la nappe a produit des conditions fortement réductrices dans le niveau supérieur et une mobilisation de l'arsenic. Un modèle analytique simple montre que les échelles de temps pour la drainance vers le bas, à partir de la surface au travers de l'imperméable supérieur vers l'aquifère semi-captif, sont de l'ordre de quelques dizaines d'années. Resumen. Muchas ciudades en el sur y sudeste de Asia carecen de sistemas de saneamiento, por lo que las aguas residuales urbanas son a menudo vertidas bien directamente al suelo o bien a canales de aguas superficiales. Esta práctica puede provocar la contaminación difusa de las aguas subterráneas someras. En Hat Yai, al sur de Tailandia, la percolación de aguas residuales urbanas ha producido un deterioro substancial de la calidad del acuífero somero sobre el que se sitúa la ciudad. Por ello, la mayor parte del suministro de agua potable se obtiene a partir de aguas subterráneas de acuíferos semiconfinados más profundos, localizados entre 30 y 50 m bajo la superficie. No obstante, el goteo desde el acuífero freático constituye una fracción importante de la recarga al acuífero profundo, hecho que tiene implicaciones en lo que respecta a la calidad del agua a largo plazo. Se presentan en este artículo los resultados de testigos de sondeos y de multi-piezómetros someros. El alto contenido en materia orgánica de las aguas urbanas, unido a la cercanía del nivel freático, ha producido la movilización de arsénico al crearse condiciones altamente reductoras. Un modelo matemático sencillo indica que el tiempo de tránsito desde la superficie hasta el acu

    The use of fiber optics in communications and data transmission applications has become wide spread in the last decade. At the same time fiber optic sensors have not gained wide commercial acceptance even though many are known and indeed numerous U.S. and foreign patents have been granted. Camino Laboratories a small medical device concern has successfully marketed a fiber optic pressure monitoring system and become a leader in the area of intracranial pressure (ICP) monitoring. Some curiosity about the company and its products has been expressed. This presentation will briefly give a background of the company, an explanation of the product, an account of the transfer from concept to volume manufacture and a word on limiting drawbacks of an intensity modulating fiber optic sensor.

    There are many different means to determine physical parameters of stars and their abundances by spectral analysis. In our work we draw our attention to the rotational and microturbulence velocities as well as metallicities for the stars of known effective temperature and surface gravity. We carried fits of LTE synthetic spectra to the observed spectra of HD10700 and HD146233. THese stars are knows aa solar-twins except slightly higher rotational velocities in both cases and higher magnetical activity i of HD10700. We adopted ABEL software (Pavlenko Ya.V.) to fit to HD10700, HD146233 spectra obtained on Camino Observatory, Chilie. Selected stars looks like. We compare our results with previous work of Valenti & Fischer (2005).

    Thermally-sprayed zinc anodes are used in both galvanic and impressed current cathodic protection systems for reinforced concrete structures. The Albany Research Center, in collaboration with the Oregon Department of Transportation, has been studying the effect of electrochemical aging on the bond strength of zinc anodes for bridge cathodic protection systems. Changes in anode bond strength and other anode properties can be explained by the chemistry of the zinc-concrete interface. The chemistry of the zinc-concrete interface in laboratory electrochemical aging studies is compared with that of several bridges with thermal-sprayed zinc anodes and which have been in service for 5 to 10 years using both galvanic and impressed current cathodic protection systems. The bridges are the Cape Creek Bridge on the Oregon coast and the East Camino Undercrossing near Placerville, CA. Also reported are interfacial chemistry results for galvanized steel rebar from the 48 year old Longbird Bridge in Bermuda.

    The objective of this study was to determine if in-gel chloramine-T radioiodination adequately labels OM proteins to allow for accurate and precise structural comparison of these molecules. Therefore, intrinsically /sup 14/C-amino acid labeled proteins and /sup 125/I-labeled proteins were cleaved with two endopeptidic reagents and the peptide fragments separated by HPLC. A comparison of retention times of the fragments, as determined by differential radiation counting, thus indicated whether /sup 125/Ilabeling identified of all the peptide peaks seen in the /sup 14/Clabeled proteins. Results demonstrated that radioiodination yields complete and accurate information about the primary structure of outer membrane proteins. In addition, it permits the use of extremely small amounts of protein allowing for method optimization and multiple separations to insure reproducibility.

    Shunt dysfunction is a common situation in neurosurgery. Often symptoms, physical examination and radiology are not enough to set a diagnosis. ICP continuous monitoring is a safe and reliable tool that provides valuable information about CSF dynamics in these patients. Not only quantitative analysis is needed but also a qualitative one that enables pathological waves identification, because high amplitude B waves are strongly related to shunt dysfunction. In this paper experience about ICP continuous monitoring in patients with shunt dysfunction suspect is presented. Quantitative and qualitative data analysis led to a correct diagnosis, improving all the patients treated according to this criterion. An intraparenchymatous Camino® sensor and neuroPICture software (developed by first author) for data collection and graphic representation were used. Complications related to monitoring were absent and graphics obtained useful for qualitative analysis.

    Mouse interferon preparations inhibited the multiplication of mouse leukemia L 1210 cells cultivated under steady-state conditions in a chemostat. The use of this sensitive and controlled system led to the detection of a rapid inhibition in the incorporation of (3-H)thymidine into cellular acid-precipitable material 2 hr after the addition of interferon, whereas an effect on cell multiplication was not detected until 22 hr later. Interferon exerted only a transitory effect on the incorporation of (3-H)uridine into acid-precipitable material and no effect on the incorporation of 14-C-amino acids into cellular protein. It is suggested that the chemostat offers many advantages for the investigation of those physiologic factors or chemotherapeutic substances that modify cell division. PMID:1056030

    Estimation of protein biosynthesis rate was used for rapid determination of Vibrio cholerae sensitivity to tetracycline and chloramphenicol by comparison of the bacterial cell radioactivity in samples with and without the antibiotics. For the sensitivity determination the strains were grown for 30 minutes at a temperature of 37 degrees C in nutrient media with a 14C-amino acid and antibiotic. The data of the determination were indicative of at least 10-fold difference in the amount of the amino acid assimilated by the sensitive strains in the presence and absence of the antibiotic. The value of the label incorporation into the antibiotic resistant strains under the above conditions did not differ. Complete coincidence of the results obtained upon parallel testing of the strain antibiotic sensitivity by the rapid and routine methods was observed.

    Mouse interferon produced by C-243 cells induced with Newcastle disease virus was isotopically labeled by adding either (/sup 35/S)methionine or a /sup 14/C-labeled amino acid mixture to the culture medium. A method combining butyric acid and theophylline treatment and resulting in high interferon yields was used. Following purification by two-step affinity chromatography on poly(U) and antibody columns, the resulting material was analyzed on SDS-PAGE. The migration pattern of radioactivity and interferon coincided well and autoradiography revealed three major bands at migration distances corresponding, respectively, to 35, 28, and 22 K. Interferon represented 3.8% of all (/sup 35/S)methionine-labeled proteins and 2.6% of all /sup 14/C-amino acid-labeled proteins released into the medium.

It compares the Report (Informe) that he presented to the Comisión de Reformas Sociales (1884) with his later writings published in the socialist press ("Farmacia y cooperación obrera,, 1914 and "La locura en los niños. Camino del remedio", 1916). We observe the discrepancies between the political-programme documents and the articles centring on professional questions and highlight how his theoretical focus is modified when applied to matters of medical practice.

    Tetranychus urticae Koch (Acari: Tetranychidae) is considered the main pest of strawberry. Several factors can favor its development, among them the genotype susceptibility and cropping system. The aims of this study were to evaluate the agronomic performance of strawberry cultivars under different managements and to identify strawberry cultivars that meet tolerance to T. urticae and high fruit yield. Thirteen cultivars of strawberry ('Albion', 'Aleluia', 'Aromas', 'Camarosa', 'Camino Real', 'Campinas', 'Diamante', 'Dover', 'Festival', 'Seascape', 'Toyonoka', 'Tudla', and 'Ventana') under three managements (open field, low tunnel, and high tunnel) were evaluated. The T. urticae attack to different cultivars was influenced by managements, being low tunnel the one that provided higher infestations in the most evaluated cultivars. 'Camarosa' was the cultivar with the lower incidence of pest and 'Dover' had the higher infestation. The genotype most suitable for growing under different managements is the 'Festival' genotype, since it meets tolerance to T. urticae, high fruit yield, and phenotypic stability.

  2. Paleoecology of unusually well-preserved west coast Upper Cretaceous fossil deposit: Point Loma Formation, Carlsbad, California

    Macroinvertebrate fossils are best preserved in southern California Upper Cretaceous strata in the Point Loma Formation at Carlsbad, California. Large bulk-rock samples were removed from a construction site (now covered) that exposed the upper Point Loma at the Carlsbad Research Center. Collections made from a nearby roadcut of the Point Loma along El Camino Real were also studied. The dominant macroinvertebrate (31% of 978 individuals) is an undescribed aporrhaoid gastropod. Although aporrhaoids are present in most Upper Cretaceous deposits in North America, the abundance of these herbivorous mollusks within the Point Loma is unusual. Suspension feeders, including the bivalves Limopsis (28%), Indogrammatodon (5%), Corbula (5%), and Ostrea (4%), form the major trophic group present within this sample (total 57%). Deposit feeders and a diverse suite of predators form the remainder of the paleocommunity (total 4% and 8%, respectively). The two dominant taxa comprise the trophic nucleus of an aporrhaoid-Limopsis paleocommunity. Two taxonomically similar subpopulations can be distinguished within the studied Point Loma. At the El Camino Real site, sandy mudstones supported a subpopulation that attained full adult size. However, at the Carlsbad Research Center, homogeneous mudstones lacking sand yield diminutive fossils of the aporrhaoid-Limopsis paleocommunity. Ichnological evidence of a thixotropic mud bottom indicates that the size reduction was a result of sinking into the unstable substrate rather than other causes (e.g., low oxygenation or salinity). The thixotropic nature of the mudstone contributed to the exceptionally well-preserved fauna. Molluscan hard parts were rapidly buried. Bivalve ligaments, residual color banding, nacreous aragonite, and larval gastropods are preserved. After burial, the low-permeability mudstone insulated skeletons from carbonate dissolution.

    The objective is to reflect on historicity and temporality as paths for the transcendence of being elderly, based on the phenomenological concepts of Martin Heiddeger. A review of the concepts of transcendence, historicity and temporality was carried out in the work of Martín Heidegger, integrating them in the perspective of nursing for the elderly. The transcendence of the elderly adult is feasible by accessing the temporality of self in the path of its historicity to arrive at the understanding of itself that he has achieved: transcending, which is but a process of the Being itself. Being is time in itself existing in the world, existence given by the encounter of the past (to have been), present and future (becoming), the same encounter that determines the historicity of the Being. The encounter has been consummated and the Being is transcendence, with the understanding of the Being itself as a supreme point. RESUMEN El objetivo es reflexionar en la historicidad y temporalidad como caminos para la trascendencia del ser adulto mayor, basado en los conceptos fenomenológicos de Martín Heiddeger. Se llevó a cabo una revisión de los conceptos de trascendencia, historicidad y temporalidad en la obra de Martín Heidegger, realizando su integración en la perspectiva de enfermería al adulto mayor. La trascendencia del ser adulto mayor es factible accediendo a la temporalidad del mismo en el camino de su historicidad para llegar a la comprensión de sí a la que ha llegado: trascendiendo, que no es sino un proceso del mismo ser. El ser es el tiempo en sí mismo existiendo en el mundo, existencia dada por el encuentro del pasado (haber sido), presente y futuro (devenir), mismo encuentro que determina la historicidad del ser. El encuentro se ha consumado y el ser es trascendencia, como punto supremo la comprensión del ser mismo.

    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.

    Objectivo: construir un modelo predictivo que mejore la estimación del peso del recién nacido (PFE). Material y Métodos: Estudio observacional dónde 140 gestantes fueron estudiadas mediante un muestreo bietápico en un Departamento de Salud en España. Fueron clasificadas en cuatro grupos dependiendo del IMC pregestacional materno. El peso proyectado al nacer fue estimado por la ecografía realizada entre las 33-35 semanas de gestación (PP40s). Se construyó un modelo de regresión con las variables que se reaccionaban con el peso al nacer, altura uterina (AU), PP40s, edad gestacional (EG), nivel de ferritina y cigarillos consumidos. Resultados: Se construyó un modelo multivariante para el grupo Normo-peso para estimar el peso al nacer (PFm) obteniendo una R2=0,727 (p.

    Objetivo: Estimar la bondad de ajuste del modelo Motivación- Habilidad-Oportunidad (MHO), a fin de evaluar la varianza observada en las preferencias para comer fruta y el consumo actual de fruta en niños escolares mexicanos; así como la invarianza factorial a través del género y tipo de población (urbana y semi-urbana) en la que residen los niños. Métodos: Se diseñó un modelo con siete constructos de un cuestionario validado que mide preferencias, habilidades cognitivas, actitudes, modelamiento, percepción de barreras, accesibilidad en la casa, accesibilidad en la escuela y la frecuencia de consumo de fruta. El cuestionario se aplicó en una muestra representativa de 1434 niños escolares de 10 a 12 años, de quinto y sexto grado de educación primaria, en un estudio transversal y ex post facto realizado en 2013 en seis ciudades del Estado de Chihuahua, México. Resultados: El modelo MHO mostró índices de ajuste adecuados y explicó el 39% de la varianza en las preferencias para comer fruta. La estructura del modelo muestra muy buena estabilidad en la estructura factorial y las dimensiones de la escala fueron equivalentes en las muestras analizadas. Conclusión: La modelización mediante ecuaciones estructurales muestra un modelo parsimonioso que, puede ser utilizado para explicar las variaciones en el consumo de fruta en niños escolares mexicanos de 10 a 12 años. La estructura del modelo fue estrictamente invariante y muestra evidencias de validación cruzada. Finalmente, se discuten las modificaciones requeridas para obtener un mejor ajuste de los datos en contextos escolares y las directrices a seguir en futras investigaciones.

    , nous avons observé un plus grand effet du rôle paternel plus que maternel sur le lien entre le conflit et la croyance filiale réciproque atténuée ainsi qu'entre la menace perçue et les problèmes internalisés. Les implications pour la compréhension des processus de médiation responsables pour tous les effets indirects, même ceux qui sont accessoires, et le plus grand impact du conflit avec le père plus qu'avec la mère sont discutés. Les limites de l'étude et les considérations pour la recherche future sont aussi abordées. La investigación empírica ha demostrado que el conflicto entre padres e hijos está positivamente relacionado con pobre ajuste en adolescentes; no obstante, el proceso subyacente no ha sido examinado adecuadamente. Para explorar posibles caminos, se eligieron la creencia filial recíproca y la amenaza percibida con el objetivo de representar dos posibles mecanismos explicativos de cómo el conflicto padres-hijos daña la percepción de los adolescentes de su relación con los padres y su auto-percepción dentro de su marco de valoración cognitiva. El primero actúa atenuando el afecto de los hijos hacia los padres y el último bajando su auto-percepción. Este estudio también distingue los problemas interiorizados de los exteriorizados para examinar si la baja creencia filial recíproca es un mediador más fuerte de la relación entre el conflicto con los padres y los problemas exteriorizados de los adolescentes y si la amenaza percibida es un mediador más fuerte de la relación entre el conflicto con los padres y los problemas interiorizados de los adolescentes. Se han planteado las siguientes hipótesis: (1) cuanto más conflicto entre padres e hijos refieran los adolescentes, menor será el reconocimiento de la creencia filial recíproca, lo cual llevará a inadaptación, sobre todo, exteriorizada; (2) cuanto más conflicto entre padres e hijos refieran los adolescentes, mayor será la amenaza percibida, lo cual llevará a

    Introduccion. La cefalea como sintoma es una patologia frecuente y uno de los principales motivos de consulta por parte de atencion primaria. Objetivo. Analizar las caracteristicas de los pacientes derivados desde atencion primaria a la consulta de neurologia general con cefalea o neuralgia como motivo de consulta, y la concordancia diagnostica. Pacientes y metodos. Estudio descriptivo transversal de todos los pacientes remitidos desde atencion primaria; se recogieron variables demograficas/clinicas y se compararon las hipotesis diagnosticas de atencion primaria y neurologia, determinando su concordancia. Resultados. Se remitieron desde atencion primaria 2.514 pacientes (588 de ellos con caracter preferente); en 378 casos el motivo de la consulta fue cefalea o neuralgia (42,46 años de media; el 77,8%, mujeres). En 139 pacientes se establecio tan solo un diagnostico semiologico y en el resto predominaron la migraña episodica (49,79%), la cefalea tensional cronica (18,41%) y la neuralgia del trigemino (12,13%). Desde neurologia, los diagnosticos mas frecuentes fueron, respectivamente, 33,86%, 24,05% y 18,67%. Se obtuvo un coeficiente kappa de 0,543 (p < 0,05), compatible con una concordancia moderada al considerar solo los pacientes remitidos desde atencion primaria con un diagnostico concreto. Conclusiones. Las cefaleas constituyen un motivo de consulta desde atencion primaria muy frecuente (15%). La concordancia diagnostica es moderada en nuestro sector sanitario, por lo que es necesario diseñar programas de formacion que ayuden a perfilar los criterios de derivacion al especialista y mejorar la atencion a nuestros pacientes.

  11. Investigation on drug solubility enhancement using deep eutectic solvents and their derivatives.

    PubMed

    Li, Zheng; Lee, Ping I

    2016-05-30

    Deep eutectic solvent (DES) is a room temperature liquid typically formed by mixing two solid compounds, such as a quaternary ammonium salt (QAS) (e.g. choline chloride) and a hydrogen bond donor (HBD) (e.g. urea or a carboxylic acid) at their eutectic composition. Very often, a range of room temperature liquids can also be obtained near the eutectic composition. Hence, it is more convenient to introduce a more general term deep eutectic solvent derivatives (DESDs) to describe a wide range of DES-like derivatives including those derived from ternary mixtures. The melting point of the mixture is lowered because the hydrogen bonding between DESD components reduces the lattice energy of components of the eutectic system. Based on the analysis of available data for 22 such choline chloride-based DES pairs, we found that the observed melting point depression can be statistically correlated with the difference between the hydrogen bonding contribution (δh) and the polar contribution (δp) to the solubility parameter of the hydrogen bond donor (HBD) component. The correlation was validated with a new DESD based on glycolic acid and choline chloride, which form DESDs at a molar ratio between 1:1 and 1:4 with DES-like properties. As a room temperature liquid, this DESD exhibits a wide range of solubility enhancement on several weakly basic poorly water-soluble drugs. For example, the solubility of itraconazole, piroxicam, lidocaine, and posaconazole has been observed to increase by 6700, 430, 28, and 6400-fold, respectively as compared to their aqueous solubility at room temperature. Furthermore, another new ternary DESD based on choline chloride, glycolic acid, and oxalic acid at a molar ratio of 1:1.6:0.4 is shown to further increase the solubility of itraconazole to a remarkable level of 5.36mg/mL (a 53,600-fold increase!). Because the components of such DESDs can include those biodegradable ones that had previously been used in formulated human products, the potential

    2003-08-01

    A estatística de lentes gravitacionais constitui uma poderosa ferramenta utilizada na obtenção de vínculos sobre parâmetros cosmológicos, principalmente sobre modelos com uma constante cosmológica. Embora de forma às vezes controversa, antes de 1998, a análise tradicional mostrava que modelos com o parâmetro de densidade da matéria da ordem da unidade são preferidos. Esse resultado começou a ser questionado, alguns anos atrás, com as indicações, advindas da análise de supernovas com alto valor de desvio para o vermelho, de que nosso Universo está acelerando. Atualmente há enorme interesse em saber qual é a natureza da componente responsável pela aceleração cósmica. Energia escura é a denominação usual dessa componente e sua característica principal é possuir pressão negativa. Nos modelos cosmológicos tradicionais, além da energia escura, considera-se também uma outra componente de origem desconhecida. Ela é denominada matéria escura e possui pressão nula. Mais recentemente modelos unificadores em que energia escura e matéria escura são manifestações distintas de um mesmo fluido (altas densidades matéria escura, baixas densidades energia escura) foram sugeridos. Um desses modelos é conhecido como Gás de Chaplygin Generalizado que é o modelo que investigaremos. Em nosso trabalho apresentamos vínculos sobre parâmetros desse modelo usando a estatística de lentes gravitacionais. Usamos observações de quasares na faixa do visível e consideramos extinção em nosso estudo. Análises semelhantes anteriores com esse tipo de objetos e que não consideram extinção são inconsistentes. Comparação dos vínculos obtidos através de lentes gravitacionais com outros advindos de outros testes será também apresentada.

    Neste trabalho, a formação estelar e evolução quí mica em galáxias Compactas Azuis (Blue Compact Galaxies - BCGs) foram estudadas através da comparação de previsões de modelos de evolução quí mica a várias razões de abundância quí mica observadas nestas galáxias. Modelos detalhados com recentes dados de nucleossí ntese e que levam em consideração o papel desempenahdo por supernovas de ambos os tipos (II e Ia) na evolução galáctica foram desenvolvidos para as BCGs permitindo seguir a evolução de vários elementos quí micos (H, D, He, C, N, O, Mg, Si, S, Ca, e Fe). O modelo é caracterizado pelas prescrições adotadas para a formação estelar, a qual ocorre em vários surtos de atividade separados por longos perí odos quiescentes. Após ajustar os melhores modelos aos dados observacionais, as previsões destes modelos foram comparadas também a razões de abundância observadas em sistemas Damped Lyman alpha (DLAs) e a origem do N (primária ou secundária) foi discutida. Alguns dos resultados obtidos são: i) as razões de abundância observadas nas BCGs são reproduzidas por modelos com 2 a 7 surtos de formação estelar com eficiência entre n = 0.2-0.9 Gano-1; ii) os baixos valores de N/O observados nestas galáxias são um resultado natural de uma formação estelar em surtos; iii) os modelos para BCGs podem reproduzir os dados dos DLAs, iv) uma quantidade "baixa" de N primário produzido em estrelas de alta massa pode ser uma explicação para os baixos valores de [N/a] observados em DLAs.

    To evaluate whether accredited health organizations perform better management practices than non-accredited ones. The study was developed in two stages: a literature review, and a study of multiple cases in 12 healthcare organizations in the state of São Paulo, Brazil. It surveyed articles comparing hospital accreditation with the EFQM (European Foundation for Quality Management) model of excellence in management. According to the pertinent literature, the accreditation model and the EFQM model are convergent and supplementary in some aspects. With 99% confidence, one can say that there is evidence that accredited organizations scored better in the evaluation based on the EFQM model in comparison to non-accredited organizations. This result was also confirmed in the comparison of results between the categories Facilitators and Results in the EFQM model. There is convergence between the accreditation model and the EFQM excellence model, suggesting that accreditation helps the healthcare sector to implement the best management practices already used by other business sectors. Avaliar se as organizações de saúde acreditadas possuem melhores práticas de gestão do que as não acreditadas. A pesquisa foi dividida em duas etapas: revisão da literatura e estudo de casos múltiplos com 12 organizações de saúde, localizadas no estado de São Paulo ‒ Brasil. Foram pesquisados artigos que comparavam a acreditação hospitalar com o modelo de excelência em gestão da EFQM (European Foundation for Quality Management), sendo que a literatura pertinente considera que o modelo de acreditação e o modelo da EFQM são convergentes e, ao mesmo tempo, complementares em determinados aspectos. Com 99% de confiança, pode-se afirmar que há evidência de que as organizações com acreditação obtiveram uma pontuação maior na avaliação baseada no modelo EFQM comparativamente às organizações não acreditadas.

  15. Bacteriostatic and bactericidal modes of action of bis(tributyltin)oxide on Legionella pneumophila.

    Soracco, R J; Pope, D H

    1983-01-01

    The modes of action of bis(tributyltin)oxide (TBTO) doses between 1 X 10(4) and 6 X 10(7) molecules per cell on a single environmental isolate of Legionella pneumophila were studied by monitoring the following parameters: (i) growth, (ii) cell viability, (iii) 14C-amino acid incorporation, (iv) 14CO2 production from 14C-amino acids, (v) [3H]uridine incorporation, (vi) [3H]thymidine incorporation, (vii) oxygen consumption, (viii) cellular ATP levels, and (ix) adenylate energy charge. The amount of TBTO associated with the cells in these laboratory cultures was also compared with that remaining in the suspending medium. Most of the TBTO (68 to 88%) was found to be associated with the cells. This result explained why the cellular responses which were measured did not correlate with the TBTO concentration, but rather with the dose of TBTO to which the cells were exposed. At the lower TBTO doses tested (10(4) to 10(7) molecules per cell) a log-normal relationship was observed between the reduction in growth rate and the TBTO concentration. At intermediate TBTO doses (ca. 10(7) molecules per cell) growth stasis occurred, with nearly 100% of the cells in these cultures remaining viable for at least 5 h after treatment. The cellular function which seemed to be primarily affected at these levels of TBTO was the energy conversion mechanism, since the decline in the rates of CO2 production, oxygen consumption, and macromolecular synthesis was preceded by an immediate (within 1 min) drop in the intracellular levels of ATP and the adenylate energy charge. At the higher TBTO doses greater than 10(7) molecules per cell) an initial, precipitous, drop in the number of viable cells was observed, which was followed by a further exponential reduction of viable cells in the treated culture. This dramatic increase in bactericidal activity with a slight increase in the TBTO dose indicated that the modes of bacteriostatic and bactericidal action of TBTO were different. PMID:6186198

    Microbial activity in the dark ocean plays a critical role in nutrient and elemental cycling. Here, we investigated the activity of archaea and bacteria on the single-cell level during dark incubations of Pacific Ocean water, and specifically their capacity for chemoautotrophy. Samples were collected 19 km off the coast of Los Angeles, at a depth of 150 m, and off the coast of San Francisco, at the surface. Incubations were amended with isotopically-labeled organic or inorganic carbon (13C-bicarbonate, 15N-amino acids or dual-labeled 13C-15N-amino acids), and uptake was detected using nanoscale secondary ion mass spectrometry (NanoSIMS). We analyzed 4,968 individual cells using an automated NanoSIMS analysis with particle-recognition software. After 7 days, 95% and 89% of cells (deep and shallow, respectively) demonstrated anabolic activity, i.e., incorporation of at least one isotopically-labeled substrate. Chemoautotrophy was detected at both sites, with 36% and 9% of cells (deep and shallow, respectively) assimilating 13C-bicarbonate in the dark. Fluorescence in situ hybridization coupled to NanoSIMS analysis was performed to link 16S rRNA phylogeny to patterns of C-assimilation. Thaumarchaea were found to dominate chemoautotrophy at both sites, with 13C-bicarbonate assimilation in nearly all cells hybridized with the Cren537 probe, but none hybridized with a general bacterial probe (Eub338). Conversely, widespread assimilation of both 15N and 13C from 15N-13C-amino acids was observed in the bacterial assemblage, but not in the Thaumarchaea. Interestingly, Thaumarchaeal cells were enriched in 15N after incubation with 15N-13C-amino acids, but not 13C, suggesting selective N assimilation from amino acids or substrate recycling. Together, our results demonstrate the value of single-cell measurements in characterizing patterns of C metabolism in mixed microbial community, and underscore the importance of Thaumarchaea in marine chemoautotrophy.

  17. Nurse staffing in a decentralized organization: part II.

    It must be emphasized that none of the steps described in this planning process emerged overnight. Rather, they were achieved through a process of evolution, sometimes through trial and error, and always with consultation and participation by many members of the hospital nursing staff. Participation by many in the process of planning for a workable staffing system has been essential to its success. Indeed, creative scheduling by the head nurse is possible because of the way in which the system has been organized. The fact that head nurses are responsible for staffing their own units makes it infinitely easier for them to see what they need to make their units operate effectively and efficiently. Creative scheduling includes the possibility of arranging nurses' hours outside the rigid three-shift schedule used by so many hospitals. Many El Camino nurses now report for work at different hours. In addition, the use of flexible work weeks has proven valuable. Some head nurses now allow for a ten-hour, four-day work week; in emergency staffing situations there have, on occasion, been twelve-hour days. Even as this system evolves, it faces change. Just as the requirements for staff cannot be rigid, so must problem solving be flexible and constantly under review. The fact that El Camino believes in constant monitoring of its system is essential to its success. A key philosophical foundation of decentralization is that it must be subject to change. This is no less true in staffing than in other parts of the decentralization structure. By agreeing that change is constant and necessary and that participation is required at all levels of the staffing planning process, we have constructed the outlines of a system that will work in the future as well as it does in the present. Our system centers around the head nurses. It involves their planning; thus it also involves the support of those members of the nursing staff who can provide essential information. But the decisions

    The Mexican arm of the Camino Verde trial of community mobilisation for dengue prevention covered three coastal regions of Guerrero state: Acapulco, Costa Grande and Costa Chica. A baseline cross-sectional survey provided data for community mobilisation and for adapting the intervention design to concrete conditions in the intervention areas. Trained field teams constructed community profiles in randomly selected clusters, based on observation and key informant interviews. In each household they carried out an entomological inspection of water containers, collected information on socio-demographic variables and cases of dengue illness among household members in the last year, and gathered paired saliva samples from children aged 3-9 years, which were subjected to ELISA testing to detect recent dengue infection. We examined associations with dengue illness and recent dengue infection in bivariate and then multivariate analysis. In 70/90 clusters, key informants were unable to identify any organized community groups. Some 1.9% (1029/55,723) of the household population reported dengue illness in the past year, with a higher rate in Acapulco region. Among children 3-9 years old, 6.1% (392/6382) had serological evidence of recent dengue infection. In all three regions, household use of anti-mosquito products, household heads working, and households having less than 5 members were associated with self-reported dengue illness. In Acapulco region, people aged less than 25 years, those with a more educated household head and those from urban sites were also more likely to report dengue illness, while in Costa Chica and Costa Grande, females were more likely to report dengue illness. Among children aged 3-9 years, those aged 3-4 years and those living in Acapulco were more likely to have evidence of recent dengue infection. The evidence from the baseline survey provided important support for the design and implementation of the trial intervention. The weakness of

    Dengue is a serious public health issue that affects households in endemic areas in terms of health and also economically, imposing costs for prevention and treatment of cases. The Camino Verde cluster-randomised controlled trial in Mexico and Nicaragua assessed the impact of evidence-based community engagement in dengue prevention. The Mexican arm of the trial was conducted in 90 randomly selected communities in three coastal regions of Guerrero State. This study reports an analysis of a secondary outcome of the trial: household use of and expenditure on anti-mosquito products. We examined whether the education and mobilisation activities of the trial motivated people to spend less on anti-mosquito products. We carried out a household questionnaire survey in the trial communities in 2010 (12,312 households) and 2012 (5349 households in intervention clusters, 5142 households in control clusters), including questions about socio-economic status, self-reported dengue illness, and purchase of and expenditure on insecticide anti-mosquito products in the previous month. We examined expenditures on anti-mosquito products at baseline in relation to social vulnerability and we compared use of and expenditures on these products between intervention and control clusters in 2012. In 2010, 44.2% of 12,312 households reported using anti-mosquito products, with a mean expenditure of USD4.61 per month among those who used them. Socially vulnerable households spent less on the products. In 2012, after the intervention, the proportion of households who purchased anti-mosquito products in the last month was significantly lower in intervention clusters (47.8%; 2503/5293) than in control clusters (53.3%; 2707/5079) (difference - 0.05, 95% CIca -0.100 to -0.010). The mean expenditure on the products, among those households who bought them, was USD6.43; 30.4% in the intervention clusters and 36.7% in the control clusters spent more than this (difference - 0.06, 95% CIca -0.12 to -0

L'évolution hydrochimique de la lentille d'eau douce est reconstituée, révélant que les principales réactions chimiques sont l'échange de cations, la dissolution de calcite et l'oxydation de matières organiques. La formation et l'évolution de la lentille d'eau douce sont modélisées en recourant à un modèle en deux dimensions de transport de soluté dépendant de la densité la sensibilité au drainage et les conductivités sont étudiées. Le niveau du drainage influence surtout la profondeur de la lentille d'eau douce, alors que le temps de formation de la lentille est surtout influencé par la conductivité. Resumen. La distribución de las aguas dulces y salinas en acuíferos costeros está influenciada por muchos procesos. Se ilustra la influencia de la heterogeneidad del medio y de la interferencia humana mediante acciones tales como la recuperación de terrenos en la llanura costera belga, donde, hacia el año 1200 D.C., se aprovechó un medio sometido a fluctuaciones mareales. La salinidad del acuífero, que fue invadido por agua salada, está siendo rebajada desde entonces. La distribución espacial de turba, arcilla, limo y arena influencia el flujo general y la distribución de agua dulce y salina, además de afectar el esquema de drenaje, y origina el desarrollo de lentejones de agua dulce. Se inspecciona la calidad del agua en y en torno a los lentejones de agua dulce bajo la cresta de un canal mareal invertido. Se reconstruye la evolución hidroquímica de los lentejones de agua dulce, proponiendo como reacciones principales el intercambio catiónico, la disolución de calcita y la oxidación de materia orgánica. Se modela la formación y evolución de los lentejones mediante un modelo bidimensional de transporte con densidad variable, y se estudia la sensibilidad del drenaje y de las conductividades. El nivel de drenaje influencia sobretodo la profundidad de los lentejones de agua dulce, mientras el tiempo

Los resultados hidroquímicos indican que el agua evaporada se ha desplazado al menos 100 m hacia el Este y que no hay un movimiento apreciable de la salmuera hacia el río Murray, situado al Sur. Se emplea el modelo para considerar varios escenarios de gestión. La carga de sal hacia el río Murray es mayor en el escenario "más negativo", que incluye irrigación entre la balsa y el propio río. Las condiciones actuales de funcionamiento llevan a un pequeño (si existe) movimiento de la salmuera desde la balsa hasta el río.

    orientale. Quatre types de salinisation de l'eau souterraine ont été identifiés : une drainance verticale en provenance d'eaux saumâtres sous-jacentes dans les régions nord-centrales, ouest et est, une intrusion marine dans la région est, une intrusion d'eau de sebkha dans la région sud-ouest, et le retour d'irrigation dans un secteur localisé de la région sud-ouest. Quatre démarches alternatives de gestion de la qualité des eaux souterraines, acceptables par les services chargés de l'eau à Bahreïn, sont discutées et des zones d'action prioritaire sont proposées, selon le type et l'étendue de chacune des sources de salinisation et en fonction des usages de les eaux souterraines dans chaque secteur. L'efficacité des options de gestion proposées pour le contrôle de la dégradation de la qualité de l'aquifère de Damman devrait être ensuite évaluée au moyen d'un modèle de simulation. Resumen El acuífero de Damman, el más importante de Bahrein, se explota para usos agrícolas y domésticos. La sobreexplotación del mismo ha provocado su salinización por cuerpos de agua salada y salobre cercanos. Un estudio hidroquímico identificó las fuentes de salinización y ayudó a dibujar sus áreas de influencia. La calidad del agua subterránea se modifica significativamente en la dirección del flujo, desde el noroeste del país, donde las entradas son laterales y procedentes de Arabia Saudí, hacia el sur y el sudeste. Se han identificado cuatro tipos de salinización: flujo ascendente de agua salobre en las regiones norte-central, este y oeste; intrusión de agua marina en la región este; intrusión de agua salobre al sudoeste y, finalmente, retorno de riego en un área local de la región oeste. Se discuten cuatro alternativas para la gestión del agua y se proponen áreas prioritarias basadas en el tipo y la extensión de cada fuente de salinización y en los usos de agua subterránea en cada zona.

    zones hydro-chimiques reflète principalement la distribution moderne des charges hydrauliques mais est incohérente avec une dépression dans le niveau d'eau dans la partie centre-ouest du bassin, ce qui indique que cette dépression est un élément transitoire du système aquifère plutôt qu'un élément à long terme. Les âges radiocarbones ajustés aux réactions géochimiques et aux processus de mélange et d'évapotranspiration/dilution qui ont lieu dans l'aquifère sont presque identiques aux âges non ajustés et varient de la période moderne jusqu'à 30 ka. Les gradients d'âge établis à partir des nids de piézomètres s'étendent de 0.1 à 2 a cm-1 et suggèrent un taux de recharge d'environ 3 cm a-1 le long du front des montagnes à l'est et pour l'infiltration provenant du Rio Grande près d'Albuquerque. Il y a eu substantiellement moins de recharge le long du front des montagnes à l'est, au nord et au sud d'Albuquerque. Se utilizaron datos químicos e isotópicos de agua subterránea a lo largo de la cuenca central del río Grande, Nuevo México, EEUU, para identificar y mapear el flujo de agua subterránea de 12 fuentes de agua a la cuenca para evaluar edades por medio de radio carbon y para refinar el modelo conceptual del sistema acuífero del Grupo Santa Fé. Se puede establecer zonas hidrotérmicas que representan el flujo de agua subterránea a lo largo de miles a miles de decenas de años en grandes distancias a través del sistema acuífero principalmente siliclástico. Las ubicaciones de las zonas hidroquímicas mayormente reflejan la distribucion de la cabeza hidráulica pre-desarollo moderna pero son inconsistentes con una depresión en los niveles de agua pre-desarollo en la zona central oeste de la cuenca. Esto indica que esta depresión es un rasgo transitorio y no un rasgo de largo plazo del sistema acuífero.

    éothermal profond. Entre les deux zones, le flux de chaleur est beaucoup plus faible. Afin de déterminer le rôle du flux d'eau souterraine dans la distorsion des isothermes dans cette zone, des analyses du gradient thermal en fonction de la température ont été réalisées elles ont permis de définir les composantes majeures du système aquifère régional. Une modélisation deux-dimensionnelle pour la simulation a ensuite contribué à la compréhension non seulement de la cause des variations horizontales du flux de chaleur dans cette région, mais également du contraste entre les propriétés des réservoirs superficiel et profond. Resumen. En los sedimentos porosos de las tierras bajas de Ishikari, hay un incremento gradual en el gradiente geotérmico desde el río Ishikari (3-4 °C 100 m-1) hacia la zona elevada del sudoeste (10 °C 100 m-1). Sin embargo, el gradiente geotérmico a profundidades someras difiere de la distribución de fondo. A pesar de las pérdidas por el flujo convectivo de calor asociadas generalmente al flujo de aguas subterráneas, el flujo de calor permanece elevado (100 mW m-2) en el área de recarga, hacia el sudoeste de la cuenca del Ishikari, la cual pertenece a un campo geotérmico activo. Al nordeste de las tierras bajas, el flujo de calor alcanza 140 mW m-2, probablemente por el flujo ascendente de agua procedente del campo geotérmico profundo. Entre ambas áreas, el flujo de calor es mucho menor. Para examinar el papel del flujo hidráulico en la distorsión de las isotermas de esta región, se ha comparado el gradiente térmico con la temperatura, con lo cual se ha podido definir los componentes mayoritarios del sistema de flujo de las aguas subterráneas. El uso de modelos bidimensionales ha servido para comprender no sólo del origen de las variaciones horizontales del flujo de calor en este campo, sino también el contraste entre las propiedades térmicas de los reservorios someros y profundos de aguas subterráneas.

    planning. Tamaño de Extensión Geográfica y Evaluación de Riesgo de Extinción en Especies Nómadas Resumen El tamaño de extensión geográfica se conceptualiza frecuentemente como un atributo fijo de las especies y se trata como tal para los propósitos de cuantificación de riesgo de extinción; se asume que las especies que ocupan extensiones geográficas más pequeñas tienen un riesgo de extinción más alto, cuando todo lo demás es igual. Sin embargo, muchas especies son móviles y sus movimientos varían desde migraciones de ida y vuelta relativamente predecibles hasta movimientos irregulares complejos, como los que muestran las especies nómadas. Estos movimientos pueden llevar a expansiones sustanciales temporales y a una reducción de las extensiones geográficas, todo esto con el potencial de llegar a niveles que pueden presentar un riesgo de extinción. Al enlazar los datos de presencia con las condiciones ambientales al momento de la observación de las especies nómadas pudimos modelar las distribuciones dinámicas de 43 especies de aves de zonas áridas a lo largo de la isla de Australia durante cada mes a lo largo de once años y calculamos el tamaño de extensión mínima y el alcance de las fluctuaciones en el tamaño de extensión geográfica a partir de estos modelos. Hubo una enorme variabilidad en la distribución espacial pronosticada a lo largo del tiempo: diez especies variaron en el tamaño de extensión geográfica por más de una orden de magnitud y dos especies variaron por más de dos órdenes de magnitud. Durante situaciones de condiciones ambientales pobres, varias especies que actualmente no se encuentran clasificadas como amenazadas a nivel global redujeron sus extensiones a áreas muy pequeñas, esto a pesar de su gran tamaño de extensión geográfica normal. Este hallazgo genera preguntas sobre lo idóneo de las evaluaciones convencionales del riesgo de extinción con base en el tamaño estático de extensión geográfica (p. ej

    -born (with similar health needs, i.e. horizontal inequity). Factors associated with immigrants’ access to, and use of, healthcare were sex, urban/rural status, education and country of origin. Conclusion There were significant associations between SES, and access to and use of healthcare among immigrants in Chile and a higher prevalence of no health care provision entitlement among poor and disabled immigrants compared to the Chilean-born. Changing associations between access and use of healthcare and SES among immigrants in Chile over time may reflect changes in their socio-demographic composition or in the survey methodology between 2006 and 2009. Resumen Introducción La evidencia internacional indica menor acceso y uso de servicios de salud por parte de inmigrantes, pero sus factores desencadenantes varían significativamente dependiendo del contexto. Algunas investigaciones se han desarrollado en este tema en América Latina, desde una perspectiva cualitativa. Este estudio cuantitativo exploró el auto-reporte de acceso y uso de servicios de salud de inmigrantes en Chile y los comparó con la población chilena. Métodos Análisis secundario de datos de encuesta nacional CASEN 2006 y 2009. Inmigrantes fueron comparados con chilenos en características demográficas (edad, sexo, urbano/rural, composición del hogar, etnia), estatus socioeconómico (educación, ingreso, situación contractual), tipo de previsión (pública, privada, otra, ninguna), y uso de varios servicios de atención primaria. Análisis descriptivo, estratificado, y modelos de regresión ponderados para entender factores asociados al acceso y uso de servicios de salud en STATA 11.0. Resultados Se observó un aumento de reporte de inmigrantes y de la desigualdad en el ingreso de inmigrantes entre 2006 y 2009.

    sensitivité ont montré que l'investigation de la couverture du sol est suffisante pour l'estimation locale de la RN du fait que l'eau traversant le plan du flux nul se trouverait sous la zone des racines et échapperait à l'évapotranspiration. La RN simulée sur les 0.70 m du sol sous les conditions d'équilibre était de 364 mm, ce qui est comparable aux mesures. Se propone un método sencillo para calibrar el modelo de doble porosidad "MACRO" mediante medidas in-situ obtenidas por TDR durante un breve ensayo de infiltración (2,8 horas), con el objetivo de estimar la recarga local al acuífero. Ésta ha sido modelada de dos formas: considerando los 3 m de suelo no saturado y empleando sólo desde la capa superior hasta el plano de flujo nulo (de 0 a 0,70 m). Se compara la recarga modelada con la recarga local medida en campo, la cual fue de 313 mm durante un ciclo anual (del 15 de octubre de 1990 al 15 de octubre de 1991). Las mejores simulaciones corresponden a la hipótesis de columna entera no saturada en condiciones de equilibrio, excluyendo el efecto de macroporos (valor de 330 mm), mientras que el resultado obtenido para condiciones de no equilibrio en la recarga local está sobreestimado (378 mm). Los análisis de sensibilidad muestran que la investigación del horizonte superior del suelo es suficiente para estimar la recarga local en este caso, ya que el agua almacenada por debajo de esta profundidad parece estar fuera del alcance típico de las raíces de la vegetación y no puede ser evapotranspirada. La recarga modelada en condiciones de equilibrio para la capa superior de 0,70 m de espesor es de 364 mm, valor aceptable respecto a las medidas.

Cet article présente une vue d'ensemble des réalisations de projets et des défis. Resumen El Estado de Guanajuato, situado en el centro de México, ocupa menos del 2% de la superficie del país. Tiene casi 17.000 pozos profundos, de los cuales se extrae cerca de 4.000 hm3/a, lo que supone un exceso de 1.000 hm3/a respecto a la recarga anual. Puesto que el agua es administrada a nivel federal en México, el gobierno del Estado afronta el reto de asegurar el desarrollo de la población sin disponer de medios formales de intervención. Dadas las limitaciones para aplicar políticas y medidas reguladoras, el programa del agua en el Estado tiene como objetivo principal la implantación de una doble estrategia. Por un lado, desarrollar estudios hidrogeológicos básicos y modelos matemáticos de flujo y transporte de los acuíferos, basándose en una campaña exhaustiva de pozos existentes y en una revisión del marco geológico del Estado.
