  2. Militarism and world health.

    PubMed

    Kiefer, C W

    1992-04-01

    Militarism is a rapidly growing factor in that complex network of social, political and economic causes of ill health among the world's poor. This complex of causes is driving a spiral of class inequality, political instability, and military repression in many less developed nations. These nations share a uniform security doctrine, which has major health impacts. Here five impacts are noted: diversion of resources, suppression of dissent, military classism, environment damage, and crime and terrorism. The demand stimulated by the recent Persian Gulf War for expensive, high-technology weapons may deepen Third World debt and fuel the cycle of poverty, ill health, social unrest, and military oppression. International health workers need to take account of the causes and effects of militarism in their studies of health problems. Their work could be aided by organizations that promote disarmament and environment preservation. PMID:1604366

  10. Honeywell militarized color liquid crystal displays for the F-16

    NASA Astrophysics Data System (ADS)

    Wood, Ted

    1996-05-01

    A fully militarized color multifunction display for the F-16 has been completed and is in the first months of production. This high performance display is a tightly integrated ensemble of optical, electronic, mechanical, and thermal designs, Many of the elements are critically interdependent, requiring fine-tuning to achieve the exceptional performance required by the F-16 environment. With no cooling air available on the F-16, the thermal requirements, both specified and implicit, dominated the design process. The high luminance requirements, in combination with a high resolution display, concentrated a great deal of heat in the display module. As a result, thermal efficiency and management were paramount. Temperature stability and performance of the liquid crystal material itself, stability of the polarizers, optical and electronic efficiency and heat extraction design required intense scrutiny.

  12. The elephant in the room: critical reflections on militarism, war, and their health contingencies.

    PubMed

    McGuire, Sharon; Boyle, Joyceen

    2008-01-01

    This philosophical analysis critically explores an archeology of militarism as an underpinning to multiple forms of violence, especially war. Deconstructing militarism and its discourses reveal it as a pervasive geographical, cultural, political, and psychological presence. New war technologies, related health and environmental problems, injuries, social suffering, and disproportionality in military spending as a threat to health are uncovered. Continuing the dialogue in formal nursing associations, critiquing media complicity in securing consent for war, and reconstructing a nonviolent, healthier world through nonviolent resistance are advocated.

    Objective: The purpose of this study was to explore the effect of PERIOD3 (PER3) genotypes on circadian rhythmicity in flight cadets after militarized management. Methods: We performed a preliminary study in 146 newly enrolled male flight cadets. Venous blood samples were collected, and genotyping of PER3 (4/5) was determined by using PCR. The morningness-eveningness questionnaire (MEQ) survey was given to flight cadets upon enrollment and after militarized management for 24 months respectively. Comparison of frequency distribution of PER3 genotypes between cases and controls (120 well-matched civilians) was performed using the X2 test. We also compared the circadian rhythmicity upon enrollment and 24 months after enrollment in flight cadets, and analyzed the connection of changes in circadian clock with PER3 genotypes. Results: The frequency distribution of PER3 genotypes in flight cadets was not significantly different from that in controls subjects. MEQ survey results showed chronotype within flight cadet group varied widely at the two time-points: the moderately morning type (50%) and the neither type (41.1%) upon enrollment; the neither type (76.7%) and the moderately morning type (21.2%) 24 months after enrollment. The circadian rhythm of individuals with the PER3 (5/5) genotype showed no significant difference before and after 24 months of militarized management, whereas notable changes were found in individuals with the PER3 (4/4) genotype (n=116, X2=37.26, P < 0.001). Conclusion: In conclusion, we provide some evidence that circadian rhythm of flight cadets with the PER3 (5) allele are less likely to be affected compared to those with the PER3 (4) allele.

  18. 'This place isn't worth the left boot of one of our boys': Geopolitics, militarism and memoirs of the Afghanistan war.

    PubMed

    Woodward, Rachel; Jenkings, K Neil

    2012-11-01

    This paper argues for the continued significance of the text as a source and focus in critical geopolitical inquiry. It establishes the utility of the military memoir in explorations of popular contemporary geopolitical imaginaries, and considers the memoir as a vector of militarism. The paper examines the memoirs written by military personnel about service in Afghanistan with the British armed forces, specifically about deployments to Helmand province between 2006 and 2012. The paper explores how Afghanistan is scripted through these texts, focussing on the explanations for deployment articulated by their authors, on the representations they contain and promote about other combatants and about civilian non-combatants, and the constitution and expression of danger in the spaces and places of military action which these texts construct and convey. The paper then turns to consider how a reading of the military memoir with reference to the genre of testimonio might extend and inform our understanding and use of these texts as a source for exploring popular geopolitics and militarism.

  1. Desarrollo curricular, conciencia ambiental y tecnologia para estudiantes de intermedia: Una investigacion en accion

    NASA Astrophysics Data System (ADS)

    Rodriguez Ramos, Teresita

    Se llevó a cabo una investigación en acción con los propósitos de 1) documentar las relaciones de las tecnologías de la información y la comunicación en las clases de ciencias de escuela intermedia como elemento de apoyo cuando se aborda el tema ambiental y sus conceptos pertinentes, a partir de las observaciones de la investigadora, así como las entrevistas y diarios reflexivos de los estudiantes de una escuela intermedia en la zona metropolitana, y luego 2) diseñar una unidad instruccional sobre el tema ambiental que integre actividades tecnologías para el curso de ciencias de la escuela intermedia según el modelo PROCIC y las observaciones que hayan iniciado los estudiantes participantes. Finalmente, se plantearon las implicaciones educativas para el currículo del Programa de Ciencias al instrumentar este modelo de unidad mediante PROCIC, e integrado la tecnología y el tema ambiental. Los hallazgos se analizaron y se categorizaron de acuerdo con las preguntas de investigación. El hallazgo principal de la investigación aborda las cuatro relaciones centrales en las que se articula la utilización de las tecnologías y sus aplicaciones en la clase de ciencias. Estas cuatro relaciones que recogen la posición de los estudiantes son: 1) Perspectiva de los estudiantes hacia la tecnología. 2) Participación de los estudiantes en los aspectos docentes. 3) Aprendizaje estudiantil sobre el ambiente, y 4) Conciencia ambiental en relación con la vida diaria. Estas relaciones ponen de manifiesto,cómo se plantea en las implicaciones, la necesidad de más investigación en acción en la sala de clases, la importancia—como tema transversal—de la conciencia ambiental mediante la tecnología al construir conocimientos significativos dentro y fuera de la escuela, asó como, valorar la investigación y la dialogicidad en la sala de clases como actividades que obligan al reexamen de la práctica didáctica en su formas curriculares de objetivos, recursos, actividades, evaluación, entre otros. Estos planteamientos definen la unidad curricular que se propone en el cuatro capítulo.

  4. Las propiedades de las estrellas extrañas en el marco de una nueva ecuación de estado para la materia extraña

    NASA Astrophysics Data System (ADS)

    Lugones, G.; Benvenuto, O. G.

    Se estudian las propiedades generales de las estrellas constituídas por materia extraña (ME) en el marco de una nueva ecuación de estado (EOS) en la que consideramos la masa de los quarks como dependiente del número medio de bariones por unidad de volumen. Se asume esta dependencia de forma que los quarks sean livianos (pesados) a densidades altas (bajas). En esta aproximación, la EOS de la ME es similar a la predicha por el modelo de la Bolsa del MIT, pero es significativamente mas dura a bajas densidades. Esta propiedad modifica las propiedades de las estrellas extrañas en forma notable. Encontramos que, con esta nueva EOS, los objetos pueden ser más masivos que en el caso de la EOS de la bolsa del MIT y que, además, pueden presentar mayores redshifts gravitatorios en hasta un 10%. En el caso de las oscilaciones radiales de estos objetos, calculamos la relación período vs. redshift gravitacional y encontramos una expresión analítica simple para el caso de las oscilaciones de objetos de baja masa. Encontramos que, aún con hipótesis muy diferentes en cuanto a la ecuación de estado de la materia extraña, las propiedades generales de estos objetos no se ve afectada en forma fundamental, y, por lo tanto, no deberían ser muy diferentes de las aquí expuestas.

  8. Radioastronomía: Una Mirada Más Amplia

    NASA Astrophysics Data System (ADS)

    Bianchi, Viviana

    2004-12-01

    The existence of the celestial bodies is known due to the light they emit. But light is a small part of a bigger phenomenon known as electromagnetic radiation. The representation of all kinds of electromagnetic radiation as a function of its frequency is called the electromagnetic spectrum. If we only studied the visible part of the spectrum, we would ignore a great deal of information. The celestial bodies emit radiation in all the regions of the electromagnetic spectrum, with very different intensity. To capture these data, astronomers design new types of telescopes that capture radiation at different wavelengths, among them the radiotelescopes that, as the name indicates, detect radio waves. The radiotelescope can be compared to a regular radio set. A radio station sends information by means of radio waves. The radio set captures these waves by means of its antenna, processes it and reproduces the information (music, etc.) in audible form. In the field of radioastronomy, interesting observations can be carried out: radio emission from stars, nebulas, pulsars, distant galaxies and stars, radiogalaxies, the Milky Way, the Sun, Jupiter, etc. La presencia de los cuerpos celestes se conoce gracias a que emiten luz. Pero la luz constituye solo una pequeña parte de un fenómeno mucho mas amplio conocido como radiación electromagnética. La representación de todas las clases de radiación como función de su frecuencia se denomina espectro electromagnético. Si solo estudiáramos la parte visual del espectro ignoraríamos una gran cantidad de información. Los cuerpos celestes emiten radiación en todas las regiones del espectro electromagnético, aunque con muy distinta intensidad. Para captar estos datos, los astrónomos deben diseñar nuevos tipos de telescopios que puedan captar la radiación de distintas longitudes de ondas, entre ellos los radiotelescopios, qué como su nombre lo indica detectan ondas de radio. El radiotelescopio puede compararse a un aparato de radio familiar. Una estación emisora está enviando información por medio de ondas de radio. El aparato de radio capta estas ondas mediante su antena, la procesa y el receptor reproduce la información (música, etc.) en forma audible. En el campo de la radioastronomía se pueden realizar observaciones interesantes: Radioestrellas, nebulosas, púlsares, galaxias y estrellas lejanas, radiogalaxias, la Vía Láctea, el Sol, Júpiter, etc.

  12. Militarism, human welfare, and the APA Ethical Principles of Psychologists.

    PubMed

    Summers, Craig

    1992-01-01

    A case study is presented of the American Psychological Association (APA), as a health care organization that promotes human welfare. APA includes policies on human welfare in its Ethical Principles of Psychologists and even lists the advancement of psychology "as a means of promoting human welfare" on its letterhead. Nevertheless, APA has other policies and activities based on military and weapons work that appear to conflict with its promotion of human welfare. Although military work in and of itself may not necessarily be problematic, work that contributes to people purposely being harmed or killed should be squared with the association's ethical guidelines. The results presented here show that this may not be the case: There currently appears to be little justification in the Ethical Principles for work intended to harm people. APA's active lobbying, research, and development for the military are documented here, in relation to an analysis of the Ethical Principles. APA's uncritical support for Operation Desert Storm is examined specifically, with regard to weapons technology and therapeutic treatment of U.S. soldiers on the battlefield. This one-sided support for victims of the war is not in keeping with a Hippocratic health care ethic to treat patients needing care, and to do so with neutrality and impartiality. Similarities to a historical example of nationalistic mental health ethics are discussed, with a review of the development of the German Institute for Psychological Research and Psychotherapy and of the German Society for Psychology in the Nazi wartime effort and the Holocaust. The results here show similar deficiencies in APA's ethical standards, not the least of which is that the code applies to individual members but not to APA policies, committees, or activities. This article concludes with suggested criteria for the Ethical Principles that would at least (a) recognize the ambiguities in systematically developing and using weapons to hurt people and (b) provide an initial rationale of potential justifications.

  20. Observaciones del disco solar y de una protuberancia quiescente en radiación ultravioleta

    NASA Astrophysics Data System (ADS)

    Cirigliano, D.; Vial, J.-C.; Rovira, M.

    Observaciones del disco solar y de una protuberancia quiescente en el rango de longitudes de onda ultravioleta fueron obtenidas con el instrumento CDS (Coronal Diagnostic Spectrograph) y SUMER (Solar Ultraviolet Measurements of emitted radiation) a bordo de la sonda SOHO. El propósito es investigar las velocidades macroscópicas de varias especies metálicas que se observan tanto en el disco solar como en el plasma de las protuberancias. Para calcular las velocidades del disco solar aplicamos una técnica mixta para modelar la distribución de estructuras en UV en el Sol quieto. Las velocidades macroscópicas en las protuberancias se calcularon a partir de los corrimientos Doppler en cada línea espectral y luego se tomaron las del disco solar como referencia. Obtuvimos valores absolutos para las velocidades macroscópicas entre 5 y 40 km/seg. También detectamos comportamientos diferentes en las velocidades de las protuberancias en el centro con respecto a los bordes.

    The aim of the research: detection of changes in free radical oxidation at treatment of parodontitis with combination of preparations - antioxidant Phenovin and immunomodulator Una de gato. Reactive compounds of nitrogen, oxygen and lipids in saliva, blood and gingival tissue of patients suffering from moderate form of parodontitis has been studied by means of the electronic paramagnetic resonance (EPR) method and spin-traps (DETC, DMPO, PBN - Sigma). In patients with parodontitis content of free NO in saliva and blood increases, while in gingival tissue - decreases. In saliva, blood and gingival tissue of patients intense EPR signals of superoxidradicals (O2(-)) and lipoperoxides (LOO(-)) has been revealed indicating intensification of processes of lipid peroxidation in oral cavity, as well as in whole organism of patient. Exaggerated synthesis of NO in saliva and blood of patient is determined by high- expression of inducible NO-synthase triggered by oxidative stress, and increased activity of neuronal NO-synthase in saliva as a result of high concentrations of metacholine and P substance intensely secreted at parodontitis. Decreased content of free NO in gingival tissue of patients with parodontitis compared to control is the result of biological degradation of nitric oxide (conversion of NO into peroxinitrite on the background of intense oxidative stress in oral cavity) and nitrosylation of mitochondrial electron transport proteins of gingival tissue (characteristic for parodontitis) with further decrease in content of free oxide, suppression of intensity of mitochondrial respiration, energogenesis, development of ischemia in oral tissue leading to further initiation of destructive processes and progression of parodontitis. Treatment with combination of preparations - Phenovin and Una de gato decreased intensity of oxidative stress in organism of patients and reduced destructive processes of tissues in oral cavity. Relative normalization of oxidative metabolism in organism, restoration of NO-synthase system activity (intensity of EPR signals of spin-trapped nitric oxide and lipoperoxide radicals approach to control data) has been observed. It is concluded that combined treatment of patients suffering from parodontitis using preparations of antioxidant and immunoregulatory activity results in long-term remission of disease.

    We recently described threats to the terrestrial biological resources on the Mariana islands of Guam and Tinian resulting from the large-scale buildup of military operations. Attitudes that view these military buildup plans in a zero sum context whereby the positives of greater security and improved local economy can be attained only with corresponding negatives of environmental destruction are prevalent. We argue these attitudes oversimplify the complicated interactions between military operations and environmental damage. Here we discuss aspects of our case study that would benefit from application of game theory. Declines in ecosystem health are not unavoidable forms of collateral damage of peace-time military operations. We repeat, conservation of environmental resources is not ancillary to national security, it is integral. PMID:22808331

  10. Geomorphological significance of the palaeodrainage network on a karst plateau: The Una-Korana plateau, Dinaric karst, Croatia

    Karst plateaus often have a complex geological and geomorphological history. It is widely accepted that their development requires a long period of karst denudation. This study reconstructs the palaeodrainage network of a karst plateau, analyses its properties and establishes its geomorphological significance. The main purpose of this research was to deepen our understanding of a key stage in the evolution of karst plateaus - the transition from a fluvial land surface to one dominated by karst surface processes. The study was conducted on a large part of the Una-Korana plateau, the largest plateau in the Dinaric karst. The majority of the plateau is made of carbonate rocks of Triassic, Jurassic and Cretaceous age that set the conditions for the development of the karst. We have reconstructed the palaeodrainage network based on 1:25,000 topographic maps with 10 m contours. The transition of the surface drainage network to the underground karst drainage network is still in progress, so, depending on the degree of karstification, the drainage network was divided into three categories: active, dry and relict. It was found that 90.5% of the pre-existing drainage network has undergone some degree of karstification. The active surface drainage network gradually shifted to a dry network, then to a relict network. The surface drainage network is gradually replaced by a dense network of dolines. Today, the flat and karstified inter-fluvial area is drained underground towards the main watercourses and these drain the entire region over the surface towards the Pannonian basin. This is the largest known karst palaeodrainage network in the Dinaric karst that has been reconstructed in this way.

    Introducción: los meningiomas del foramen óptico producen un rápido deterioro de la función visual aún cuando su tamaño es pequeño, por eso su diagnóstico y manejo difiere del resto de los meningiomas clinoideos. El propósito de este estudio es presentar la técnica y los resultados de nuestro manejo quirúrgico de meningiomas foraminales (MF). Pacientes y Métodos: se llevó a cabo una revisión de las historias clínicas de 47 pacientes con meningiomas primarios intraorbitarios. Se realizaron 52 cirugías en los pacientes con MF. Se empleó una craneotomía fronto-orbitaria, seguida de una descompresión extradural del canal óptico, resección del componente intraorbitario y exploración intradural del nervio óptico. Resultados: de los 12 pacientes con MF que presentaban la visión conservada, la agudeza visual fue preservada en 7 casos, mejoró en 2, y empeoró en 3. En 18 pacientes, el principal síntoma fue exoftalmos y en 35 pacientes ceguera unilateral. Ocurrieron 6 recurrencias, 2 a 10 años después de la resección quirúrgica. Cinco de ellos fueron reoperados. Se indicó radioterapia después de la recurrencia en 3 pacientes. Conclusión: el manejo de los MF continúa siendo controvertido y frecuentemente se propone un tratamiento conservador. Basados en nuestros hallazgos de frecuente extensión intracraneal, proponemos realizar una resección total o subtotal del tumor, preservando el nervio óptico en pacientes con visión prequirúrgica conservada.

    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.

    This work is the result of the analysis of existing information in the earthquake database of the Observatorio Sismológico y Vulcanológico de Costa Rica, Universidad Nacional (OVSICORI-UNA), and seeks disclosure of basic seismological information recorded and processed in 2010. In this year there was a transition between the software used to record, store and locate earthquakes. During the first three months of 2010, we used Earthworm (http://folkworm.ceri.memphis.edu/ew-doc), SEISAN (Haskov y Ottemoller, 1999) and Hypocenter (Lienert y Haskov, 1995) to capture, store and locate the earthquakes, respectively; in April 2010, ANTELOPE (http://www.brtt.com/software.html) start to be used for recording and storing and GENLOC (Fan at al, 2006) and LOCSAT (Bratt and Bache 1988), to locate earthquakes. GENLOC was used for local events and LOCSAT for regional and distant earthquakes. The local earthquakes were located using the 1D velocity model of Quintero and Kissling (2001) and for regional and distant earthquakes IASPEI91 (Kennett and Engdahl, 1991) was used. All the events for 2010 and shown in this work were rechecked by the authors. We located 3903 earthquakes in and around Costa Rica and 746 regional and distant seismic events were recorded (see Figure 1). In this work we also give a summary of major earthquakes recorded and located by OVSICORI-UNA network between 1983 and 2012. Seismicity recorded by OVSICORI-UNA network in 2010

    Water is one of the most vital natural resource and its availability and quality determine ecosystem productivity, both for agricultural and natural systems. Una district is one of the major potential agricultural districts in Himachal Pradesh, India. More than 70% of the population of this district is engaged in agriculture and allied sectors and major crops grown are maize, wheat, rice, sugarcane, pulses and vegetables. The region faces drought every year and about 90 per cent of the area is water stressed. This has resulted in crop loss and shortage of food and fodder. The sources of drinking water, small ponds and bowlies dry-up during summer season resulting in scarcity of drinking water. Una district receives rainfall during monsoons from June to September and also during non-monsoon period (winter). The annual average rainfall in the area is about 1040 mm with 55 average rainy days. But due to heavy surface run-off the farmers not able to cultivate the crops more than once in a year. Past research indicate that the geomorphology of the Una district might be responsible for such droughts as it controls the surface as well as ground water resources. The research proposes to develop a water stress model for Una district using the geomorphic parameters, water resource and land use land cover data of the study area. Using Survey of India topographical maps (1:50000), the geomorphic parameters are extracted. The spatial layers of these parameters i.e. drainage density, slope, relative relief, ruggedness index, surface water body's frequency are created in GIS. A time series of normalized remotely sensed data of the study area is used for land use land cover classification and analyses. Based on the results from the water stress model, the drought/water stress areas and water harvesting zones are identified and documented. The results of this research will help the general population in resolving the drinking water problem to a certain extent and also the cultivators to water the crops more than twice per year which might increase the crop yield in Una district.

    Mandrini, C. H.; Démoulin, P.; van Driel-Gesztelyi, L.; Schmieder, B.; Bagalá, L. G.; Rovira, M. G.

    Se han obtenido observaciones desde Tierra (Hα y magnetogramas) coordinadas con el Soft X-ray Telescope (SXT), a bordo del satélite japonés Yohkoh, de una región activa bipolar en decaimiento. Estos datos constituyen la base para el estudio de un punto brillante en rayos X (PBX) y de la actividad relacionada con el mismo en distintas capas de la atmósfera solar. Las observaciones muestran que el PBX está relacionado con la aparición de un bipolo menor (~ 1020 Mx) y que su abrillantamiento continuo, así como sus aumentos de brillo esporádicos (``fulguraciones"), son el resultado de la reconexión entre el pequeño arco emergente (visto en Hα como un sistema de filamentos arqueados, SFA) y arcos mayores asociados al campo facular preexistente. Se ha extrapolado el campo magnético observado en la aproximación libre de fuerzas lineal y se ha seguido su evolución a lo largo de la vida del PBX. Se ha calculado la posición de las cuasiseparatrices (CSs) a partir del campo modelado. Las líneas de campo extrapoladas, cuyas bases fotosféricas se encuentran a ambos lados de las CSs, están de acuerdo con las estructuras cromosféricas y coronales observadas. Se ha calculado el espesor de la CD ubicada a lo largo de la polaridad negativa emergente, encontrándose que su variación está de acuerdo con la evolución de la intensidad del PBX; la CS es muy delgada durante la vida del PBX (~ 100 m), mientras que su espesor aumenta considerablemente (>= 10^4 m) cuando el PBX desaparece de las imágenes del SXT. Estos resultados señalan que el abrillantamiento y las ``fulguraciones" de este PBX se deben al proceso de reconexión en 3D que tiene lugar en las CSs.

    Viral diseases, including emerging and chronic viruses, are an increasing worldwide health concern. As a consequence, the discovery of new antiviral agents from plants has assumed more urgency than in the past. A number of native Amazonian medicines of plant origin are known to have antimicrobial and anti-inflammatory activity, although only a few have been studied for their antiviral properties and immunomodulating effects. Those most studied include: Sangre de Grado (drago) (Croton lechleri) in the Euphorbiaceae family and Una de Gato (Uncaria tomentosa) in the Rubiaceae family. This article reviews the chemical composition, pharmacological properties, state of current research, clinical use, and potential antiviral and immunomodulating activity of these and other plants from the Peruvian Amazon.

    Introducción: El síndrome de outlet torácico es una compresión del plexo braquial que suscita polémica. Se clasifica en Outlet Torácico Verdadero o neurogénico (OTV) y Outlet Torácico Disputado o no neurogénico (OTD). El primero presenta síntomas motores en la mano, mientras que el segundo sólo síntomas sensitivos en el miembro superior. El objetivo de este trabajo es analizar los resultados obtenidos en una serie de 31 cirugías. Métodos: Se analizaron las cirugías de nervios efectuadas entre 2003-2012, tomando los diagnósticos de outlet torácico cuyo período de seguimiento post-operatorio mínimo fuera de 6 meses. Se buscaron los siguientes datos: edad, sexo, presencia de síntomas sensitivos y/o motores, clasificación, resultado de los estudios neurofisiológicos y de imágenes, resultado de la cirugía, complicaciones post-operatorias y recidivas. Resultados: Se incluyeron 31 cirugías realizadas en 30 pacientes, 9 OTV (8 mujeres) de 24.3 años, y 21 con OTD (18 mujeres) de 37.4 años de edad en promedio. Un 90% presentaron alteraciones neurofisiológicas preoperatorias, y 66,6% imagenológicas. En el intraoperatorio, el 100% de los OTV presentó una alteración anatómica relacionada con la sintomatología, hecho observado sólo en el 36.7% de los OTD operados. El 87,5% de los OTV mejoraron sensitivamente, mientras que 77,7% mejoraron la atrofia. Por el contrario, 45.4% de los OTD mejoraron permanentemente, 36.3% no tuvieron cambios, 13.6% mejoraron transitoriamente y 4.5% (un caso) empeoró. Las complicaciones post-operatorias fueron más frecuentes aunque transitorias en el grupo de OTV (3 casos sobre 9 operados, 33.3%) que en los OTD (3 casos sobre 22, un 13.6%). Conclusión: El OTV suele mayormente mejorar luego de la cirugía, igual que el OTD aunque en una proporción mucho menor. Estos hallazgos coinciden con otros reportes recientes de esta patología.

    RESUMEN El presente artículo es una revisión sobre la contaminación del agua, el aire y el efecto del cambio climático en la salud de la población peruana. Uno de los principales contaminantes del aire es el material particulado menor de 2,5 μ (PM 2,5), en la ciudad de Lima, anualmente 2300 muertes prematuras son atribuibles a este contaminante. Otro problema es la contaminación del aire domiciliario por el uso de cocinas con combustible de biomasa, donde la exposición excesiva a PM 2,5 dentro de las casas es responsable de aproximadamente 3000 muertes prematuras anuales entre adultos, con otro número desconocido de muertes entre niños debido a infecciones respiratorias. La contaminación del agua tiene como principales causas los desagües vertidos directamente a los ríos, minerales (arsénico) de varias fuentes, y fallas de las plantas de tratamiento. En el Perú, el cambio climático puede impactar en la frecuencia y severidad del fenómeno de El Niño oscilación del sur (ENSO) que se ha asociado con un incremento en los casos de enfermedades como cólera, malaria y dengue. El cambio climático incrementa la temperatura y puede extender las áreas afectadas por enfermedades transmitidas por vectores, además de tener efecto en la disponibilidad del agua y en la contaminación del aire. En conclusión, el Perú, pasa por una transición de factores de riesgo ambientales, donde coexisten riesgos tradicionales y modernos, y persisten los problemas infecciosos y crónicos, algunos de los cuales se asocian con problemas de contaminación de agua y de aire.

    Small interfering RNAs (siRNAs) are now established as the preferred tool to inhibit gene function in mammalian cells yet trigger unintended gene silencing due to their inherent miRNA-like behavior. Such off-target effects are primarily mediated by the sequence-specific interaction between the siRNA seed regions (position 2–8 of either siRNA strand counting from the 5′-end) and complementary sequences in the 3′UTR of (off-) targets. It was previously shown that chemical modification of siRNAs can reduce off-targeting but only very few modifications have been tested leaving more to be identified. Here we developed a luciferase reporter-based assay suitable to monitor siRNA off-targeting in a high throughput manner using stable cell lines. We investigated the impact of chemically modifying single nucleotide positions within the siRNA seed on siRNA function and off-targeting using 10 different types of chemical modifications, three different target sequences and three siRNA concentrations. We found several differently modified siRNAs to exercise reduced off-targeting yet incorporation of the strongly destabilizing unlocked nucleic acid (UNA) modification into position 7 of the siRNA most potently reduced off-targeting for all tested sequences. Notably, such position-specific destabilization of siRNA–target interactions did not significantly reduce siRNA potency and is therefore well suited for future siRNA designs especially for applications in vivo where siRNA concentrations, expectedly, will be low.

    2012-12-01

    Some public-square games are presented in this paper, considered as didactic modules to help children imagine astronomical processes, based on the concept that learning in Astronomy should be developed to strengthen the relationship of our body with three-dimensional space and time, much in the same way we experience when observing the actual sky, holding a permanent "dialogue" between the actual world and what is to be learned. The games presented (merry-go-rounds and slides) were designed to work on the astronomical concepts related to the translation of the Earth around the Sun, the phases of the Moon and gravity, and on what is perceived by an observer about those phenomena. The description of each game, their physical and astronomical foundations, and a critical comment about their didactical importance are the key parts of the paper. Finally, a recommendation is given about the role teachers should play to be essential partners in the process of learning Astronomy by means of the interaction with these games. Se presentan en este trabajo algunos juegos de plaza, considerados como módulos didácticos para imaginar procesos astronómicos, a partir de la concepción de que el aprendizaje en Astronomía debe desarrollarse fortaleciendo la relación del propio cuerpo con el espacio tridimensional y con el tiempo, tal como se vive al observar el cielo, construyendo un "diálogo" entre el mundo real y los aprendizajes a construir. Los juegos presentados (calesitas y toboganes) fueron diseñados para trabajar sobre la traslación de la Tierra en torno al Sol, las fases de la Luna y la gravedad, y sobre lo que un observador percibe de los mismos. Se da la descripción de cada juego, se discuten sus fundamentos físicos y astronómicos, y se desarrolla una crítica didáctica de los mismos. Finalmente, se comenta el rol que deberían tener los docentes en el acompañamiento a los aprendices en el proceso de interacción con los juegos presentados.

    Rivera Pacheco, Andres

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

    The clinical use of small interfering RNA (siRNA) is hampered by poor uptake by tissues and instability in circulation. In addition, off-target effects pose a significant additional problem for therapeutic use of siRNA. Chemical modifications of siRNA have been reported to increase stability and reduce off-target effects enabling possible therapeutic use of siRNA. Recently a large scale direct comparison of the impact of 21 different types of novel chemical modifications on siRNA efficiency and cell viability was published.1 It was found that several types of chemical modifications could enhance siRNA activity beyond that of an unmodified siRNA in vitro. In addition, a novel siRNA design, termed small internally segmented interfering RNA (sisiRNA), composed of an intact antisense strand and segmented guide strand stabilized using LNA was shown to be effective in cell based assays. In the present study we examined the in vivo efficacy of the LNA and UNA modified siRNA and sisiRNA in a mouse model bearing human tumor xenografts. We studied the biodistribution and efficacy of target knockdown in the mouse model. In addition we used whole genome profiling to assess the off-target effects in the liver of the mouse and the tumor xenografts. We report that LNA and UNA modified siRNA and sisiRNA improve the efficacy in target knockdown as compared with unmodified siRNA in the tumor xenografts without formulation. However, the level of off-target gene regulation in both the tumor and the liver correlated with the increase in efficacy in target knockdown, unless the seed region of the siRNA was modified.

    We present a very simple concrete model to demonstrate the concept of phases of an illuminated body. The main objective of our model is to help the understanding of the Moon phases as viewed from the perspective of an observer on Earth. The material allows the visualization of two important effects: (1st) even though all the time half Moon is illuminated by the Sun, we see different fractions of the illuminated Moon surface, depending on our angle of sight; (2nd) the orientation of the convex part of the Moon in the crescent and waning phases on the sky also depends on our perspective from Earth. The use of a closed box allows one to see the contrast among the different phases with no need of a dark room. We also present a text on the Moon phases, emphasizing the dependence of the aspect of the bright part on the angle of sight. En este trabajo proponemos la construcción de material didáctico de bajo costo para demostración del concepto de fases de un cuerpo iluminado. El principal objetivo de nuestro material es facilitar la comprensión de las fases de la Luna desde la perspectiva de un observador en la Tierra. El material ayuda la visualización de dos efectos importantes: (1º) a pesar de tener siempre la mitad de la Luna (representada por una bolita de espuma plástica o de ping-pong), iluminada por el Sol ( representado por una fuente de luz natural o artificial), vemos diferentes fracciones de su superficie iluminada, dependiendo del ángulo por el cual la vemos; (2º) la orientación del borde convexo de la Luna en las fases Creciente y Menguante también depende de la perspectiva por la cual la miramos desde la Tierra. El uso de una caja cerrada permite observar el contraste entre las diferentes fases sin necesidad de estar en un recinto oscuro. Presentamos también un texto explicativo sobre las fases de la Luna, enfatizando la dependencia de la apariencia de la parte iluminada con el ángulo de visión. Neste trabalho propomos a construção de material didático de baixo custo para demonstração do conceito de fases de um corpo iluminado. O principal objetivo de nosso material é facilitar a compreensão das fases da Lua da perspectiva de um observador na Terra. O material ajuda na visualização de dois efeitos importantes: (1º) mesmo tendo sempre a metade da "Lua" (representada por uma bolinha de isopor ou de ping-pong) iluminada pelo "Sol" (representado por uma fonte de luz natural ou artificial), nós vemos diferentes frações de sua superfície iluminada, dependendo do ângulo pelo qual a olhamos; (2º) a orientação da borda convexa da Lua nas fases Crescente e Minguante também depende da perspectiva pela qual a olhamos da Terra. O uso de uma caixa fechada permite observar o contraste entre as diferentes fases sem necessidade de estar em uma sala escurecida. Apresentamos também um texto explicativo sobre fases da Lua, enfatizando a dependência da aparência da parte iluminada com o ângulo de visada.

    RESUMEN Durante la década de 1990 en los Estados Unidos (EU), el conocimiento sobre el trastorno de estrés post-traumático (TEPT) evolucionó de estudios específicos en un principio, sobre veteranos de guerra y sobre víctimas de desastres, a estudios epidemiológicos más tarde, sin embargo, la epidemiología del TEPT en países en desarrollo ha sido un área poco estudiada hasta ahora. Los expertos en el área de trauma han propuesto que los sucesos traumáticos que ocurren en la niñez son más perjudiciales para la salud mental que aquellos que ocurren más tarde en la vida. Este trabajo revisa los resultados de un estudio epidemiológico llevado a cabo en Chile. Específicamente, se revisan los resultados sobre las tasas de prevalencia del TEPT, traumas asociados más frecuentemente con él, así como la comorbilidad de este trastorno con otros trastornos psiquiátricos a lo largo de la vida. Igualmente se analizaron las diferencias del TEPT en cada sexo, así como la exposición a traumas en una muestra representativa de chilenos. Además se comparó la prevalencia de trastornos psiquiátricos en personas que sufrieron su primer trauma durante la niñez, durante la edad adulta, o que no reportaron traumas durante su vida. En estos estudios epidemiológicos se usaron módulos del TEPT y trastorno de personalidad antisocial (TPA) de la entrevista diagnóstica siguiendo los criterios del DSM-III-R (DIS–III-R). Para evaluar el resto de los trastornos psiquiátricos se usó la Entrevista Diagnóstica Internacional Compuesta (CIDI). Estos instrumentos fueron administrados en tres ciudades chilenas a 2390 personas mayores de 15 años. Para estimar los errores estándares (EE) debido al diseño de la muestra y a la necesidad de ajuste se usó el método Taylor de linearización seriada. También se usó un análisis de regresión logística para examinar la relación entre el TEPT, los factores demográficos de riesgo y el tipo de trauma. Además se utilizó la regresión logística multivariada para evaluar si la relación entre el TEPT y el sexo pudiera ser explicada por medio de otros factores de riesgo, así como para calcular las tasas y la oportunidad relativa (razón de productos cruzados) de trastornos psiquiátricos a lo largo de la vida. El primer análisis arrojó que la prevalencia de TEPT a lo largo de la vida fue de 4.4% (2.5% para hombres y 6.2% para mujeres). De los hechos traumáticos reportados, la violación sexual tuvo una correlación más alta con el TEPT que los demás hechos traumáticos. Las mujeres tuvieron más probabilidades de experimentar TEPT que los hombres, después de controlar la variable asalto violento. El segundo análisis evidenció que los que habían sufrido traumas a lo largo de la vida tuvieron mayor probabilidad de tener un trastorno psiquiátrico en comparación con aquellos que no reportaron traumas. También se encontró que los que sufrieron su primer trauma durante la infancia tuvieron más probabilidad de desarrollar trastornos de pánico a lo largo de la vida que aquellos que sufrieron su primer trauma en la edad adulta, independientemente del número de traumas que sufrieron y de las diferencias demográficas. Aunque Chile tiene un contexto histórico-cultural y una economía diferente a otros países en los que se ha estudiado anteriormente la epidemiología del TEPT, el presente estudio reflejó tendencias similares a las reportadas en estudios previos. Los hallazgos expuestos enfatizan la importancia de investigar la prevalencia del TEPT, los patrones de comorbilidad del TEPT y las diferencias de sexo en la prevalencia del TEPT en diferentes países. También estos resultados sugieren que los sucesos traumáticos en la infancia (y no en la adultez) pueden estar relacionados con la ocurrencia de trastornos psiquiátricos específicos. PMID:21113425

    This paper presents one of the concepts of Astronomy and its consequent failure in teaching this topic in high school, even when the official documents point out the necessity of Astronomy teaching at this school level. Among the spontaneous conceptions in Astronomy that high school students carry with them, even after the end of the school, we emphasized in this research the Moon phases. The development of different strategies in relation to traditional methods, aimed to teaching-learning process on this topic was considered in this study. These strategies were devised based on the reference frame of the Meaningful Learning, as elaborated by Ausubel. The proposals presented here include the active participation of students in experimental activities and other didactic activities, for their continuous evaluation during the process. These activities finished with a Comics elaboration about the Moon phases. Therefore, the objective of this paper is to present a proposal for differentiated teaching activity about Moon phases supported by the theoretical principles of Meaningful Learning at Physics classes. Este texto foca um dos conteúdos de Astronomia e a consequente falha no ensino deste tema no ensino médio, apesar de os documentos oficiais apresentarem a necessidade de se trabalhar a Astronomia neste nível de ensino. Dentre as concepções alternativas em Astronomia que os alunos do ensino médio carregam consigo, mesmo após o término dos estudos, destacamos, nesta pesquisa, o fenômeno das fases da Lua. O desenvolvimento de estratégias diferenciadas em relação ao ensino tradicional, visando o processo de ensino-aprendizagem sobre este tema, foi contemplado neste trabalho como um dos resultados obtidos sob a luz dos referenciais da aprendizagem significativa, fundamentados em Ausubel. Segundo a proposta aqui apresentada, a participação ativa dos alunos na execução de uma atividade experimental e outras atividades didáticas, que visam sua contínua avaliação durante o processo, culmina com a elaboração de uma história em quadrinhos envolvendo as fases da Lua. Portanto, o objetivo deste trabalho é apresentar uma proposta de atividade didática diferenciada sustentada pelos princípios teóricos da aprendizagem significativa aplicada ao ensino das fases da Lua durante as aulas de Física no ensino médio. En este trabajo se presenta uno de los contenidos de la Astronomía y el evidente fracaso en la enseñanza del tema en la escuela secundaria, a pesar del hecho que los documentos oficiales apuntan para la necesidad de trabajar contenidos de Astronomía en este nivel. Entre los conceptos alternativos en Astronomía que los alumnos secundarios llevan consigo, aún después de terminados los estudios, destacamos aquí el fenómeno de las fases de la Luna. El desarrollo de diferentes estrategias en relación con los métodos tradicionales, dirigidas al proceso de enseñanza-aprendizaje en este tema fue considerado en este trabajo como uno de los resultados obtenidos a la luz de los referenciales del aprendizaje significativo, tal como fueron fundamentados por Ausubel. Según la propuesta que aquí se presenta, la participación activa de los estudiantes en la ejecución de una actividad experimental y otras actividades educativas destinadas a la evaluación continua durante el proceso culminó en la elaboración de una historieta respecto de las fases de la Luna. Por lo tanto, el objetivo de este trabajo es presentar una propuesta de actividad de enseñanza diferenciada con el apoyo de los principios teóricos del aprendizaje significativo aplicado a la enseñanza de las fases de la luna durante las clases de física del ciclo secundario.

    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 unidad, segun evidencia los productos finales del ABPr. La interaccion con el docente es muy importante para mediar los conflictos y desacuerdos que surgen como parte de las interacciones entre pares. Por lo tanto, el uso de diversas estrategias de andamiaje por parte del docente durante las reuniones de los grupos colaborativos es esencial para el exito del modelo ABPr.

    The comet C/1999 S4 was expected to be a moderately bright object during summer 2000. It was observed by visual, photographic and CCD techniques. The derived light curve shows that the comet reached a brightness maximum (mag. 6 around July 26) corresponding to the total dissolution of its nucleus. From the analysis of the light curve a double maximum was detected, the dissolution event appearing to start around July 20. Several morphological changes were also observed during the apparition in relation to partial fragmentation events. The comet aspect completely changed during the final disruption. Relevant changes in the plasma tail were observed and they are probably related both to the activity of the nucleus and to the solar wind. A perspective anti-tail was detected in early July.

    We present the results obtained in a research on the comprehension of basic astronomical concepts, in which 561 students from fifth grade middle school to third grade high school of a public school of the city of Foz do Iguaçu (Brazil) took part. A test with 20 multiple-choice questions was applied to indentify the most common conceptions expressed by the students. This test was elaborated based on the literature about misconceptions and covered the following topics: the day-night cycle; the time zones; the seasons of the year; the phases of the Moon; the movement of the Moon; the apparent movement of the Sun in the celestial sphere; the eclipses; the dimensions and distances in the Universe; the brightness of the stars and its observation from Earth. Though a small progress was verified in the proportion of scientifically acceptable answers when comparing the eighth grade of middle school to the fifth, and the third grade of high school to the first, there was an overall predominance of alternative conceptions regarding most of the explored subjects, which persisted up to the last year of secondary school. The comparison to data found in this research made in other socio-cultural contexts revealed, in many aspects, similar notions and difficulties revealed by the students. Se presentan los resultados de una investigación sobre la comprensión de conceptos astronómicos básicos, en la cual participaron 561 estudiantes que cursaban entre el quinto grado de la enseñanza primaria y el tercer año de la enseñanza secundaria de una escuela pública de la ciudad de Foz do Iguaçu (Brasil). Se utilizó un test de 20 preguntas de opción múltiple para identificar las concepciones más comunes expresadas por los estudiantes. Este instrumento de recolección de datos se desarrolló en base a la literatura sobre las concepciones alternativas y trató los siguientes temas: el ciclo día-noche, los husos horarios, las estaciones del año, las fases de la Luna, el movimiento de la Luna, el movimiento aparente del Sol sobre la esfera celeste, los eclipses, las dimensiones y las distancias en el Universo, el brillo de las estrellas y su observación de la Tierra. Si bien ha habido un pequeño progreso en la proporción de respuestas aceptables científicamente cuando se cotejó el octavo grado de la enseñanza primaria con el quinto, y el último año de la enseñanza secundaria con el primero, se observó un predominio de las concepciones alternativas en relación a la mayoría de los temas explorados, que continuó hasta los últimos años de la educación básica. Una comparación con los datos encontrados en investigaciones realizadas en otros contextos socioculturales revelaron, en muchos aspectos, conceptos y dificultades similares expresadas por los estudiantes. Apresentam-se os resultados de uma investigação sobre a compreensão de conceitos astronômicos básicos, da qual participaram 561 estudantes da quinta série do Ensino Fundamental ao terceiro ano do Ensino Médio de uma escola pública da cidade de Foz do Iguaçu.

    This article aims to present the results of a diagnostic evaluation, used as a tool for collecting data on prior knowledge of scientific concepts needed to understand the topic "Earth and Universe", from a group comprised of 47 students of 6th grade. The educational method of diagnosing the student's prior knowledge before teaching them is founded on the Meaningful Learning theory, proposed by David Ausubel. The diagnostic evaluation consisted of 25 questions; the answers were analyzed and categorized, making possible their interpretation, which allows us to understand the meanings assigned by the student to these concepts. It follows from the diagnostic evaluation, that the majority of students surveyed had difficulties in exposing scientific concepts on the topic "Earth and Universe" when starting the 6th grade. However, we identified relevant ideas and representations that contributed to the re-signification of scientific concepts proposed for the teaching of the subject in this grade. The results of diagnostic evaluation served as reference to the organization of the syllabus, making possible the learning process by matching the sequence of teaching to the students" characteristics and context of the classroom. It is expected that other researchers in this topic can also use the instrument presented in this paper. Este artículo tiene como objetivo presentar los resultados de una evaluación diagnóstica, utilizada como una herramienta para recoger datos sobre el conocimiento previo de los conceptos científicos necesarios para comprender el tema "Tierra y Universo", de un grupo compuesto por 47 alumnos de 6º grado de la escuela primaria. La acción pedagógica del diagnóstico de los conocimientos previos del estudiante antes de enseñarles está justificada por la teoría del Aprendizaje Significativo, propuesta por David Ausubel. La evaluación de diagnóstico consistió en 25 preguntas, las respuestas fueron analizadas y clasificadas objetivando-se su interpretación, lo que nos permite comprender los significados asignados por el estudiante a estos conceptos. Se desprende de la evaluación diagnóstica que la mayoría de los encuestados ha tenido dificultades para exponer los conceptos científicos sobre el Universo y la Tierra, para iniciar el 6 º grado. Sin embargo, se identificaron ideas relevantes y las representaciones que contribuyeron a la re-significación de los conceptos científicos propuestos para la enseñanza del tema en esta serie. Los resultados de la evaluación diagnóstica han servido como referencia para la organización del Programa, facilitando el proceso de aprendizaje, haciendo coincidir la secuencia didáctica a las características de los estudiantes y el contexto del aula. Se espera que el instrumento presentado en este documento también pueda ser utilizado por otros investigadores en investigaciones relacionadas con el tema. Este artigo tem como objetivo apresentar os resultados de uma avaliação diagnóstica, utilizada como instrumento para a coleta de dados sobre o conhecimento prévio de conceitos científicos, necessários à compreensão do tema Terra e Universo, de um grupo composto por 47 estudantes, da 6ª série do Ensino Fundamental. A ação pedagógica de diagnosticar os conhecimentos prévios, do estudante, antes de ensiná-los, tem fundamento na teoria da Aprendizagem Significativa, proposta por David Ausubel. Essa avaliação diagnóstica foi composta por 25 questões, cujas respostas foram analisadas e categorizadas visando sua interpretação, o que permitiu compreender os significados atribuídos pelo estudante a esses conceitos. Conclui-se, a partir da avaliação diagnóstica, que a maioria dos estudantes pesquisados apresentou dificuldades em expor conceitos científicos sobre o tema Terra e Universo ao iniciar a 6ª série. Entretanto, foram identificadas ideias e representações relevantes que contribuíram para a (re)significação dos conceitos científicos propostos para o ensino do tema nessa série. Os resultados da avaliação diagnóstica serviram como referência para a organização do plano de ensino, viabilizando o processo de aprendizagem, por adequar a sequência didática às características dos estudantes e ao contexto da sala de aula. É esperado que o instrumento apresentado nesse artigo possa ser utilizado também por outros pesquisadores em investigações relacionadas ao tema.

    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.

    Vega Osorio, Melba

    The purpose of this research was to capture the memories, practices, thoughts and philosophies of education that four experienced Science teachers have accumulated through the years. The life story qualitative research design was used in order to collect more meaningful information from the participants amenable to in depth analysis and interpretation. The life stories interviews were conducted using an interview protocol especially designed for the study. The interviews were recorded and transcribed. The questions that guided this research are: 1. What are the meanings that science teachers give to their educational practices? 2. How did the life experiences of the participants contribute to their success as science teachers? 3. How did the participants' educational practices change and evolve over time? 4. What does teaching science mean in the life of the participants? 5. Which reflections arise from the work of the participants that impact the teaching of science? 6. What are the participants' conceptions about teachers' professional development? 7. What are the participants' contributions to the field of scientific education? Wolcott's (1994) DAI analytical model was used for the analysis of the information and the narratives were written following the three dimensions of the model: description, analysis and interpretation. According to the life stories of the participants, being a teacher requires more than teaching the content. To be a successful and an exemplary science teacher, they have to live the teaching vocation, with dedication, passion, commitment and love for teaching, for students and science; teachers have to give their best for the students, even if it means making personal sacrifices; they should keep updated in knowledge (content) and in educational innovations (strategies); emphasizing both the theoretical and the practical aspects in the field of science, and being an inspirational guide for students.

  7. Evolución de una protuberancia observada por el HASTA

    NASA Astrophysics Data System (ADS)

    Luoni, M. L.; Francile, C.

    Prominence eruptions are one of the most spectacular manifestations of solar activity; in addition to flares and coronal mass ejections. Both filaments and prominences are chromospheric material suspended in the corona by the magnetic field. Hence their importance as tracers of field ejections. Some parts of their magnetic structure are not well understood; especially with regard to the loss of stability. On 06 December 2010 the H-Alpha Telescope for Argentina (HASTA) observed a prominence in the eastern solar limb including when part of it was ejected. In this paper the evolution of the filament is analyzed; its structure before and after the eruption; determining parameters that characterize it from HASTA data. FULL TEXT IN SPANISH

    NASA Astrophysics Data System (ADS)

    Lipari, S. L.; Merlo, D. C.; Moyano, M. M.

    Optical aperture spectroscopy and CCD broad- and narrow-band images are presented for the barred Seyfert 1 galaxy: IRAS 22117-3903. IRAS data are also used to analyse this object. The CTIO broad band CCD imaging show interesting morphological features: a compact nucleus with a prominent bar; two bright spiral arms; and a partial/segmented inner ring. The narrow-band imaging show that the nuclear H+[NII] emission is concentrate mainly in the nucleus. We find optical spectral features characteristic of a Seyfert 1.5 nucleus; i.e.; showing hydrogen emission lines with broad and narrow components. We detected high excitation emission lines ([CaV]+[FeXIV]; [FeVII]). We study the stellar population in the nuclear region. We find that the stellar population that represent quite well the nuclear stellar population is an average of spiral galaxies dominated by the old population plus a contribution of young stars. Physical conditions are derived for the narrow emission line region; and we detected very high electron temperature (T=4400045000 K); untypical for the ordinary AGNs and probably associated to shocks in a starburst component. Finally; at the optical and IR wavelength; we find properties typical of an nucleus with compound nature; in good agreement with the AGN/QSOs evolutionary model of Lípari ; Terlevich (2006; ; 368; 1001).

    Sequencing mitochondrial and chloroplast genomes has become an integral part in understanding the genomic machinery and the phylogenetic histories of green algae. Previously, only three chloroplast genomes (Oltmannsiellopsis viridis, Pseudendoclonium akinetum, and Bryopsis hypnoides) and two mitochondrial genomes (O. viridis and P. akinetum) from the class Ulvophyceae have been published. Here, we present the first chloroplast and mitochondrial genomes from the ecologically and economically important marine, green algal genus Ulva. The chloroplast genome of Ulva sp. was 99,983 bp in a circular-mapping molecule that lacked inverted repeats, and thus far, was the smallest ulvophycean plastid genome. This cpDNA was a highly compact, AT-rich genome that contained a total of 102 identified genes (71 protein-coding genes, 28 tRNA genes, and three ribosomal RNA genes). Additionally, five introns were annotated in four genes: atpA (1), petB (1), psbB (2), and rrl (1). The circular-mapping mitochondrial genome of Ulva sp. was 73,493 bp and follows the expanded pattern also seen in other ulvophyceans and trebouxiophyceans. The Ulva sp. mtDNA contained 29 protein-coding genes, 25 tRNA genes, and two rRNA genes for a total of 56 identifiable genes. Ten introns were annotated in this mtDNA: cox1 (4), atp1 (1), nad3 (1), nad5 (1), and rrs (3). Double-cut-and-join (DCJ) values showed that organellar genomes across Chlorophyta are highly rearranged, in contrast to the highly conserved organellar genomes of the red algae (Rhodophyta). A phylogenomic investigation of 51 plastid protein-coding genes showed that Ulvophyceae is not monophyletic, and also placed Oltmannsiellopsis (Oltmannsiellopsidales) and Tetraselmis (Chlorodendrophyceae) closely to Ulva (Ulvales) and Pseudendoclonium (Ulothrichales).

    Appointment reminders help parents deal with complex immunization schedules. Preferred content of text-message reminders has been identified for English-speakers. Spanish-speaking parents of children under three years old were recruited to develop Spanish text-message immunization reminders. Structured interviews included questions about demographic characteristics, use of technology, and willingness to receive text reminders. Each participant was assigned to one user-centered design (UCD) test: card sort, needs analysis or comprehension testing. Respondents (N=54) were female (70%) and averaged 27 years of age (SD=7). A card sort of 20 immunization-related statements resulted in identification of seven pieces of critical information, which were compiled into eight example texts. These texts were ranked in the needs assessment and the top two were assessed for comprehension. All participants were able to understand the content and describe intention to act. Utilizing UCD testing, Spanish-speakers identified short, specific text content that differed from preferred content of English-speaking parents. PMID:23974378

    The astronomy education community has tacitly assumed that learning astronomy is a conceptual domain resting upon spatial thinking skills. As a first step to formally identify an empirical relationship, undergraduate students in a non-major introductory astronomy survey class at a mediumsized, Ph.D. granting, mid-western US university were given pre- and post-astronomy conceptual diagnostics and spatial reasoning diagnostics, Instruments used were the "Test Of Astronomy Standards" and "What Do You Know?" Using only fully matched data for analysis, our sample consisted of 86 undergraduate non-science majors. Students' normalized gains for astronomy surveys were low at .26 and .13 respectively. Students' spatial thinking was measured using an instrument designed specifically for this study. Correlations between the astronomy instruments' pre- to post-course gain scores and the spatial assessment instrument show moderate to strong relationships suggesting the relationship between spatial reasoning and astronomy ability can explain about 25% of the variation in student achievement. La comunidad de educación en astronomía ha supuesto de forma tácita que el aprendizaje de la astronomía consiste en un dominio conceptual fundamentado en el razonamiento espacial. Como un primer paso para identificar formalmente una relación empírica entre estas dos cosas, utilizamos como muestra los estudantes de graduación de carreras no científicas de un curso experimental en una universidad norteamericana del medioeste de porte mediano con programa de Doctorado em curso, en el cual estos estudiantes se sometieron a un diagnóstico de razonamiento espacial y conceptos astronómicos antes e después del mismo. Las herramientas utilizadas fueron el Test Of Astronomy Standards (TOAST) y el cuestionario What do you know? Utilizando solo los datos completamente consistentes para este análisis, nuestra muestra consistió en 86 estudantes de graduación. Las mejoras, depués de normalizadas, en el desempeño de los estudiantes en estos dos asuntos foram pequenas, 0.26 e 0.13 respectivamente. El razonamiento espacial de los estudiantes fue medido utilizando un instrumento específico desarrollado para este trabaljo. Las correlaciones entre los resultados de los tests astronómicos y este instrumento específico, antes y después del curso mostraron una relación entre moderada y fuerte, sugiriendo que la relación entre el razonamiento espacial y el conocimiento astronómico puede explicar hasta un 25% de la variación em el desempeño de los estudiantes.

    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.

  3. Calibración del retardo ionosférico en observaciones astrométricas y geodésicas a partir de observaciones GPS

    NASA Astrophysics Data System (ADS)

    Brunini, C.; Kleusberg, A.; Arias, E. F.; de Biasi, M. S.

    Los parámetros astrométricos y geodésicos de precisión se determinan hoy mediante la observación con técnicas espaciales (VLBI, GPS y LSR). Las técnicas VLBI y GPS operan en la banda de microondas y en ella la ionósfera terrestre es dispersiva. Las señales que provienen de las radiofuentes y de los satélites atraviesan la ionósfera, donde el índice de refracción difiere de la unidad en una cantidad que es proporcional a la densidad de electrones libres e inversamente proporcional al cuadrado de la frecuencia de la onda portadora. Actualmente el International GPS Service for Geodynamics (IGS) mantiene operacional una red global integrada por más de 50 estaciones equipadas con receptores GPS de alta performance; las observaciones diarias son accesibles a los usuarios mediante ftp. La posibilidad de utilizar estas observaciones en un monitoreo continuo de la ionósfera fue señalada por diversos autores, razón por la cual en los últimos años se ha invertido un significativo esfuerzo en la producción de mapas ionosféricos regionales y globales. En el presente trabajo se utilizan 28 estaciones cuyas observaciones mapean la mayor parte de la ionósfera global. Los resultados obtenidos demuestran la posibilidad de obtener mapas ionosféricos globales con una resolución de medio día y con una precisión de (1.5 nseg (rms)). Dichos mapas proveen valores medios globales para el intervalo ajustado. Los residuos del ajuste por mínimos cuadrados constituyen una señal a partir de la cual pueden estudiarse mejor las variaciones geográficas de la ionósfera y las componentes estadísticas de su variación temporal.

    Ferrero, I.; Piatti, A. E.

    The statistical analysis of a sample of data includes the collection; the analysis and the interpretation of them. For example; the construction of histograms has proven to be a powerful tool in statistics; from which it is possible to obtain an overview of the distribution of the data sample considered. In some circumstances; however; the results often depend on the way they are constructed (e.g. size of the bins used; etc.) leading to a variety of possible interpretations. Specifically; this paper presents a statistical method that allows to unravel the intrinsic distribution of a n-dimensional data distribution from "adaptive bins" and the consideration of the errors of the data used.

    Six geothermal spring sites were selected on the basis of preliminary investigations conducted in Honduras over the last decade and were evaluated in terms of their development potential. Of the six, the Platanares and San Ignacio sites have high base temperatures and high surface fluid discharge rates and appear to have the best potential for further development as sources of electrical power. A third site, Azacualpa, has a high enough base temperature and discharge rate to be considered as a back-up, but the logistical problems involved in geophysical surveys make it less attractive than the two primary sites. Of the remaining three sites, Pavana may be a source of direct-use heat for local agricultural processing. Sambo Creek and El Olivar have either severe logistical problems that would impede further investigation and development or base temperatures and flow rates that are too low to warrant detailed investigation at this time.

    PURPOSE Peer support can promote diabetes control, yet research on feasible and effective peer support models is lacking. This randomized controlled trial tested a volunteer-based model of peer support for diabetes control. METHODS Thirty-four volunteer peer leaders were recruited and trained to provide support to 5 to 8 patients each through telephone contact, in-person, individual, and group support. Planned dose was 8 contacts, preferably in the first 6 months. Patients with uncontrolled diabetes were randomly sampled from the medical records of 3 community clinics. After a baseline interview and medical records review to obtain baseline values for the primary outcome, HbA1c, 336 patient participants were randomly assigned to a 12-month peer support intervention or usual care. The assessment protocol was repeated at 6 and 12 months after baseline. RESULTS Thirty peer leaders delivered an average of 4 contacts each per assigned participant (range 1–24). Despite the lack of intervention fidelity, the intervention was effective at reducing glycated hemoglobin (HbA1c) among intervention as compared with usual care participants (P=0.05). Similar trends were observed in frequency of meeting fruit and vegetable guidelines (P =0.09), a secondary outcome. Counterintuitively, usual care participants reported checking their feet more days out of 7 than intervention participants (P =0.03). CONCLUSIONS Given the modest changes we observed, combined with other evidence for peer support to promote diabetes control, additional research is needed on how to modify the system of care to increase the level of peer support delivered by volunteers.

    2013-01-01

    The use of culturally sensitive intervention could improve mental health care for the eating disorders treatment in the Latino population. The aim of this report is to describe the rationale, design, and methods of the ongoing study entitled “Engaging Latino families in eating disorders treatment.” The primary aim of the study is to compare (a) the combined effect of individual cognitive behavioral therapy for bulimia nervosa (CBT-BN) that has been previously adapted for the Latino population plus Family Enhanced (FE) modules, with (b) the standard adapted individual CBT-BN in a proof-of-principle study with 40 Latina adults with eating disorders and one relative or significant other per patient. We hypothesize that 1) the feasibility, acceptability, and adherence of participants in CBT-BN+ FE will be superior to individual CBT-BN only; 2) relatives in CBT-BN+ FE will report greater treatment satisfaction, greater reduction in family conflict, and greater decreases in caregiver burden than relatives in the individual CBT-BN only condition; and 3) patients who participate in CBT-BN+ FE will show trends towards greater decreases in ED symptoms compared with patients in CBT-BN only; although power will be limited to detect this difference. However, we predict that they will show greater retention in treatment, greater treatment satisfaction, and greater decreases in family conflict than patients in CBT-BN only. The completion of this investigation will yield important information regarding the acceptability and feasibility of a culturally sensitive evidence-based treatment model for Latinos with eating disorders.

    HIV preventive efforts with heterosexual couples are almost nonexistent. We designed a group intervention based on the Information-Motivation-Behavioral Skills model with the aim of increasing male condom use and promoting the practice of mutual masturbation as a safer sex alternative. We carried out a pilot study with four couples to evaluate the feasibility of the intervention and the aspects of content and format that needed to be modified. Findings reflect that participants were very satisfied with the intervention and they found it entertaining and innovative. They were very comfortable with its format, as well as with the activities. The findings confirm the feasibility of this intervention and the need to direct preventive efforts to this population. PMID:23847716

    We have solved, using molecular dynamics techniques, a model which consists of a 487-particle movable overlayer on an infinite rigid substrate. The interaction J/sub 1/ between the boundary and interior atoms of the overlayer is weaker than those between interior atoms. We have found that the roughness of the border of the overlayer increases with increasing temperature and with decreasing J/sub 1/, contrary to the interpretation of Kolaczkiewicz and Bauer of their experiment of an overlayer of Au on a W substrate. We also argue that the Kolaczkiewicz-Bauer claim that their experimental setup is a realization of the Abraham model for the 2D ferromagnetic Ising model, has to be revised.

    Assuming that LTE prevails, the ionization stage was analyzed in the atmosphere of a hydrogen defficient carbon (HdC) star: Y = 0.928, Zc = 0.056, X = 7 × 10-5, and remaining elements in approximately solar abundance (Z = 0.072). It is shown that in the shallower atmospheric layers, electron density in HdC is similar to that found in normal stars (as a consequence of assuming a quite similar metal abundance); in intermediate layers, C is the principal electron-donor, resembling H in normal composition stars, but similarity is not complete, as C is not so abundant in these stars as H is in normal stars (0.70 <= X <= 0.75). In deeper layers, He is the principal electron contributor. These facts, as well as the chemical composition, bring some consequences on the absorption in the stellar atmosphere; in solar composition stars, population II and HdC stars of medium temperature (5000 <= T <= 8000 K), the importance of different absorbers was analyzed. It was found that in the visual region, the absorption in a HdC star atmosphere is smaller than in a normal star.

    Se presenta un mapa geologico digital de Venezuela sobre un fondo de relieve sombreado. Los datos geologicos e hidrologicos del norte del rio Orinoco proceden de la digitalizacion de mapas geologicos en papel a escala 1:500.000. Estos datos fueron integrados con el mapa geologico digital del Escudo de Guayana Venezolano, a su vez derivado de hojas en papel a escala 1:500.000. La informacion sobre los tipos de fallas mostrados en el mapa es igual que en las fuentes originales. Los poligonos geologicos fueron atribuidos por edad, litologia y nombre de la unidad siguiendo el Codigo geologico de Venezuela. Se incorporaron revisiones significativas de la geologia de la Cordillera de la Costa a partir de las nuevas hojas integradas a escala 1:25.000. Toda esta informacion geologico-estructural se sobrepuso a una imagen de relieve sombreado, producida por el procesamiento de los datos de radar interferometrico con 90 m (3 arcosegundos) de resolucion espacial obtenidos por la mision topografica de radar del transbordador espacial (SRTM). Las areas de la base de datos del SRTM carentes de informacion fueron llenadas por medio de la interpolacion de los datos de las celdas adyacentes. Para producir la imagen de relieve sombreado se uso una direccion de iluminacion de 315 deg con un angulo de 65 deg sobre el horizonte. La proyeccion usada en el mapa es conica equidistante, con latitudes de 4 y 9 deg norte como paralelos estandar y una longitud de 66 deg al oeste como meridiano central. Los datos en el mapa proceden primordialment de hojas a escala 1:500.000 y el producto esta preparado para una impresion optima en escala 1:750.000. Los usuarios pueden obtener ampliaciones mayores, sin embargo no se garantiza la precision del mapa a escalas mas detalladas. Especialmente en la region de Guayana, al sobreponer los mapas geologicos sobre la reciente imagen SRTM, se notan grandes discrepancias no sistematicas tanto en contactos como en fallas. Esto es debido a que los mapas geologicos de Guayana tienen como base topografica las imagenes de radar de vision lateral (SLAR), con muy control de campo de los a?os 1970's. La correccion de estos desfases esta planificada para el futuro.

    Introducción: la desnutrición relacionada con la enfermedad (DRE) afecta al menos a una cuarta parte de los pacientes hospitalizados, aumentando la morbimortalidad del paciente durante su hospitalización y al alta. Sin embargo, su repercusión en la actividad hospitalaria no está bien cuantificada.Objetivo: determinar el impacto de una adecuada codificación de la DRE y los procedimientos empleados para revertirla en el peso medio del hospital y otros índices hospitalarios.Material y métodos: estudio comparativo realizado en todos los pacientes subsidiarios de soporte nutricional artificial seguidos por la Unidad de Nutrición Clínica y Dietética de la Sección de Endocrinología y Nutrición (UNCyD-SEyN) del Complejo Asistencial Universitario de León durante los años 2008 y 2013. Se realizó un informe de codificación nutricional del diagnóstico, el tratamiento nutricional y la vía de acceso según la CIE-9-MC. Se comparó el peso medio depurado del hospital, el índice de estancia media ajustada (IEMA), la casuística e índice de funcionamiento previo a la codificación nutricional y tras la misma.Resultados: el peso medio depurado del hospital se incrementó tras la codificación, tanto en 2008 (+ 4,1%) como en 2013 (+1,7%) y especialmente en aquellos servicios en los que se realiza cribado nutricional (Hematología, +10,5%). El IEMA se redujo por debajo de 1 (-5,7% y -0,2% en 2008 y 2013), indicando un mejor funcionamiento, y también disminuyó el índice funcional (-5,6% y -0,4% en 2008 y 2013), lo que supondría una mayor eficiencia.Conclusión: la correcta codificación del diagnóstico y el tratamiento nutricional del paciente con desnutrición aumenta el peso medio depurado de un hospital de tercer nivel, y mejora el IEMA y el índice de funcionamiento.

    Immigration laws that militarize communities may exacerbate ethno-racial health disparities. We aimed to document the prevalence of and ways in which immigration enforcement policy and militarization of the US-Mexico border is experienced as everyday violence. Militarization is defined as the saturation of and pervasive encounters with immigration officials including local police enacting immigration and border enforcement policy with military style tactics and weapons. Data were drawn from a random household sample of US citizen and permanent residents of Mexican descent in the Arizona border region (2006-2008). Qualitative and quantitative data documented the frequency and nature of immigration related profiling, mistreatment and resistance to institutionalized victimization. Participants described living and working in a highly militarized environment, wherein immigration-related profiling and mistreatment were common immigration law enforcement practices. Approximately 25% of respondents described an immigration-related mistreatment episode, of which 62% were personally victimized. Nearly 75% of episodes occurred in a community location rather than at a US port of entry. Participant mistreatment narratives suggest the normalization of immigration-related mistreatment among the population. Given border security remains at the core of immigration reform debates, it is imperative that scholars advance the understanding of the public health impact of such enforcement policies on the daily lives of Mexican-origin US permanent residents, and their non-immigrant US citizen co-ethnics. Immigration policy that sanctions institutional practices of discrimination, such as ethno-racial profiling and mistreatment, are forms of structural racism and everyday violence. Metrics and systems for monitoring immigration and border enforcement policies and institutional practices deleterious to the health of US citizens and residents should be established. PMID:24705336

    This research explores the relationship between sex/gender factors and attitudes toward peace and militarism to determine whether more women than men favor non-military solutions to peace to examine the effect of gender identity on these attitudes. The investigation also looks at participation in a peace group, a military setting, child care, and the traditional homemaker role, to see what effect these activities might have on attitudes toward peace and militarism. In addition, the study explores whether there is a correlation between attitudes favorable to feminism and orientation toward war and peace issues. This study is guided by the sociological perspective which assumes that sex and gender differences, to the extent they exist, may be influenced by the social roles defined as appropriate for women and men. In this exploration there is not a sex gap on peace and military attitudes. A feminine gender identity does not have an effect on the direction of attitudes toward peace or militarism. However, an overall identification with masculine traits, plus believing oneself to be dominant, competitive and aggressive is correlated with a non-pacifist world view. Results of this study show that participation in a peace group is the best determinant of a pro-peace attitude, whereas participation in a military setting tends to be associated with a pro-military attitude.

Methods Culturally tailored, theory-based nutrition education was provided to Mexican origin Latinas aged 48 to 84. The randomized design compared participants in workshops incorporating the connection between dietary fat and brain health, participants in workshops focusing only on dietary fat and heart health, a waitlist control group, and a posttest only control group. Results Among those assigned to either intervention, there was statistically significant gain in health literacy, knowledge about dietary fat, and behaviors to reduce dietary fat compared to waitlist control. There was no difference in outcomes between those given the module about diet and brain health and those not provided that module. Discussion A program to encourage dietary fat modification in Latinas proved feasible and modestly effective. PMID:25231884

    Background Chilean women have one of the highest smoking prevalence in the world. Aim To estimate the main factors associated with smoking initiation and quitting among a cohort of adult women living in a low socioeconomic status area of Santiago, Chile. Material and methods A random population-based sample of 1,100 women, 18 years and older, were selected from a community located in the South East area of Santiago. Sociodemographic, as well as smoking, beliefs, behaviors, stages of change and nicotine addiction level were recorded during a personal interview. After an average follow-up period of 5.5 years, women were re-evaluated. Results Seventy-three percent of women completed the study. At baseline, 39% of women were smokers. At the end of the study, there was an absolute smoking rate reduction of 7.1% (p<0.001). The main variables associated with smoking initiation were younger age (Odds ratio (OR): 1.08, 95% confidence intervals (CI): 1.05–1.12), higher education level (OR: 1.2, 95% CI: 1.07–1.35), and having fewer children (OR: 1.3 95% CI: 1.01–1.66). Factors related with quitting were younger age of onset (OR: 1.06 95% CI: 1.02–1.1), higher level of nicotine dependence (OR: 4.22, 95% CI: 1.74–10.27), and higher perception of smoking addiction (OR: 4.34, 95% CI: 2–9.09). Stage of change was associated with smoking cessation but its effect was diluted after adjusting for the level of nicotine addiction. Conclusions Sociodemographic and family factors were the main variables related with initiation, whereas age of onset, belief of addiction, and nicotine dependence were the main factors related with cessation. Women with a high motivation for quitting should be evaluated for nicotine addiction level to define the best strategy for intervention (Rev Méd Chile 2009; 137: 1001–9). PMID:19915762

    We present a photometric study of the globular cluster system (GCS); associated to the lenticular galaxy NGC6861. It is based on GEMINI/GMOS images in the filters g'; r'; i' of three fields; one of them centered on the galaxy. Studying the colour-magnitude diagram of the system; we detect the presence of at least two populations of GCs (``blue'' and ``red'') and the presence of the phenomenon known as ``blue-tilt''. However; analyzing the colour distribution we infer the existence of a third population with intermediate colours which could be interpreted as evidence of a past interaction or fusion event.

    RESUMEN. Se ha estimado los efectos de marea en los pares dinamicos de galaxias elipticas. Para poder estudiar tales efectos hernos expandido el potencial gravitacional en potencias del cociente plr hasta en el orden 3 correspondientes a las fuerzas de marea. Hemos examina- do la influencia de este termino en el movimiento orbital. Se encon- tr6 el valor de M/LB = 10+7 (en unidades solares) para un ejemplo de 46 pares E-E usando Ia aproximaci6n de marea. De este resultado, no podemos concluir que existen alrededor de las galaxias halos grandes y obscuros. Hemos encontrado tambien que la suposici6n de masas puntuales es una buena aproximaci6n para el sistema fisico. Sin embargo, tal aproximaci6n sobreestima ligeramente el cociente masa-lurninosidad. ABSTRACT. In the present work we have estimated the tidal effects in the dynamics of pairs of elliptical galaxies. In order to study such effects we have expanded the gravitational potential in power of the ratio p/r up to order 3 corresponding to tidal forces. We examined the influence of this term in the orbital motion. The value of M/LB =lOi7 (in solar units) was found for a sample of 46 E-E pairs using the tidal approximation. From this result, we cannot conclude that large dark haloes exist around galaxies. We have also found that the assump- tion of point masses is a good approximation for the physical system. However, such an approximation overestimates slightly the mass-luminosity ratio. Keq wo't : GALAXIES-DYNAMICS

    The pine weevils that occur in plantations of Pinus spp. in Andean Patagonia of Argentina belong to the species Pissodes castaneus (De Geer), a Eurasian endemic species, according to the identification based on molecular and morphological characters. Sequences of the mitochondrial Cytochrome oxidase subunit I and nuclear genes (28 S rDNA and ITS2) were obtained for individuals of 13 afforestations, covering the entire distribution area of the established populations in the Andean Patagonia of Argentina. Sequence comparison with representative species of the genus (European, North American, and Chinese species) shows that Patagonian specimens are conspecific to those of P. castaneus sequenced from Europe. Phylogenetic analyses indicate that all terminals from Patagonia form a monophyletic unit without evident subclades, eliminating the possibility of existence of more than one species of Pissodes Germar in this area, including cryptic ones. Moreover, the very low genetic divergence between the Patagonian populations suggests that it is plausible that P. castaneus was introduced into Patagonia from just one location. Mitochondrial DNA analysis shows that Patagonian terminals group together with a French haplotype and are clearly separated from other P. castaneus individuals represented in our sample, and reveal that established populations in Andean Patagonia originated via a limited introduction.ResumenLos gorgojos del pino presentes en plantaciones de Pinus spp. en la Patagonia andina de Argentina pertenecen a la especie Pissodes castaneus (De Geer), una especie endémica de Eurasia, de acuerdo a la identificación basada en caracteres moleculares y morfológicos. Se obtuvieron secuencias del gen mitocondrial Citocromo oxidasa subunidad I y de dos genes nucleares (28 S ADNr y ITS2), para individuos de 13 plantaciones, cubriendo toda el área de distribución de las poblaciones establecidas en la Patagonia andina de Argentina. La comparación de estas secuencias con aquellas de especies representativas del género (especies de Europa, América del Norte y China), muestra que los especímenes de la Patagonia son conespecíficos con los de P. castaneus de Europa. Los análisis filogenéticos muestran que todos los terminales de la Patagonia forman una unidad monofilética sin subclados evidentes, descartando la posibilidad de que exista más de una especie de Pissodes Germar en esta área, incluyendo especies crípticas. Más aún, la baja divergencia genética entre las poblaciones patagónicas sugiere que es posible que P. castaneus haya sido introducida en la Patagonia desde una única localidad. Los análisis con ADN mitocondrial muestran que los terminales de Patagonia se agrupan junto a un haplotipo francés y están claramente separados de otros individuos de P. castaneus representados en la muestra, y revelan que una introducción limitada dio origen a las poblaciones establecidas en la Patagonia andina.

    Although Astronomy is one of the oldest Sciences in the world and many of its concepts are popular, it is possible to observe that a major part of the students do not know about them. This work aims to analyse the basic knowledge of the secondary school's students of a state school in the city of Suzano, related to the astronomical phenomena, which surround them. It was carried out a questionnaire of multiple choice to 34 students from the first grade, night classes, of the state school Batista Renzi. From the sample, 34 students, only 29.4% of them could understand the succession of the days; 20.6% could explain the seasons of the year and 20.6% had some idea about celestial objects nearer to the Earth. In turn, 67.6% correctly classified the Sun as a star; 55.9% related the Big Bang to the origin of Universe; only 20.6% identified the light-year as an unit of distance and 32.4% recognized a falling star as a meteor. The actual analysis was expanded to more 310 students of other classes, grades and periods of the same school. In this first stage, it can be noted the students' little discernment of the astronomical events and mainly the great confusion about the appropriate meaning of popular astronomical terms. Aunque la Astronomía es una de las ciencias más antiguas de la humanidad y muchos de los conceptos astronómicos son populares, se observa que una parcela significativa de los estudiantes se encuentra al margen de estas informaciones. El presente trabajo pretende analizar el nivel de conocimiento básico de los alumnos de la Enseñanza Media de la Red Estatal de la ciudad de Suzano con relación a los fenómenos astronómicos que los rodean. Con este objetivo fue elaborado un formulario constando de preguntas de selección múltipla, aplicado en el primer año nocturno de la Escuela Estatal Batista Renzi. En un universo de 34 alumnos se constató que solamente 29,4% comprendían la sucesión de los días; 20,6% explicaron correctamente las estaciones del año y 20,6% tenían la idea de cuales son los objetos celestes más cercanos de la Tierra. En contraposición, 67,6% clasificaron correctamente el Sol como una estrella; 55,9% relacionaron el Big Bang al origen del Universo; solamente 20,6% identificaron un año-luz como unidad de distancia y 32,4% reconocieron una estrella fugaz como meteoro. El presente análisis fue expandido para otros grupos de la Enseñanza Media, no solamente del período nocturno, sino también diurno de la misma escuela. En esta primera fase se nota el pequeño conocimiento de los alumnos sobre eventos astronómicos y principalmente la gran confusión sobre el significado correcto de los términos astronómicos populares.

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

    NASA Astrophysics Data System (ADS)

    Kulkarni, Himanshu; Vijay Shankar, P. S.; Deolankar, S. B.; Shah, Mihir

    Watershed development programmes provide an opportunity for sustainable management strategies, although currently, they remain largely `supply-side' mechanisms of water resources development. Hydrogeological conditions, community participation and status of groundwater usage are important in evolving strategies on `demand-side' groundwater management. Neemkheda aquifer is a typical low-storage, low-hydraulic conductivity aquifer from a watershed in the dryland regions of Madhya Pradesh State of central India. A shallow unconfined aquifer, it consists of an upper coarse, calcareous sandstone unit underlain by a fine-grained sandstone unit. A `well commune' of seven wells is poised to test the concept of joint groundwater management, wherein wells are mechanisms of tapping a common water source, the Neemkheda aquifer. The strategy for systematic groundwater management in the Neemkheda well commune is based upon the relationship between Transmissivity (T) and Storage coefficient (S), i.e. aquifer diffusivity, and its variation within the aquifer. Wells within a high diffusivity domain tend to dewater more quickly than wells within a low diffusivity domain. A well-use schedule during the dry season, based upon aquifer diffusivity forms the basis of the groundwater management concept. The distribution of local aquifer diffusivities governs the relationship between local and regional aquifer depletion times and forms the basis of the groundwater management exercise being proposed for the Neemkheda aquifer. Los programas de desarrollo de una cuenca hídrica son una oportunidad para el uso de estrategias de gestión sostenible, aunque hoy en día estas siguen siendo principalmente mecanismos para el desarrollo de recursos hídricos con énfasis en la ``oferta''. Las condiciones hidrogeológicas, la participación comunitaria y la condición de utilización del agua subterránea, son importantes en el desarrollo de estrategias para la gestión del agua subterránea, desde el punto de vista de la ``demanda''. El acuífero de Neemkheda es un acuífero típico de almacenamiento bajo y conductividad hidráulica baja, perteneciente a una cuenca hídrica ubicada en las regiones secas del Estado de Madhya Pradesh, en la parte central de India. Un acuífero de tipo libre, somero, formado por una unidad superior de arenisca calcárea de grano grueso, subyacida por una unidad de arenisca de grano fino. Un campo de pozos comunitario compuesto por siete pozos, pone a prueba el concepto de gestión conjunta del agua subterránea, dentro del cual los pozos son mecanismos para usar una fuente de agua común: El acuífero de Neemkheda. La estrategia usada para la gestión sistemática del agua subterránea, en el campo de pozos comunitario de Neemkheda, se basa en la relación existente entre Transmisividad (T) y Coeficiente de Almacenamiento (S), es decir en la Difusividad del Acuífero y en su variación observada dentro del mismo acuífero. Los pozos cuya difusividad esta dentro de un rango alto, tienden a experimentar un descenso en su nivel mas rápidamente que aquellos pozos con una difusividad baja. El concepto de gestión de agua subterránea se basa en un programa especial de operación para cada pozo durante la estación seca, el cual a su vez se basa en la difusividad del acuífero. La distribución de difusividades locales del acuífero rige las relaciones entre las épocas de descensos de nivel en el acuífero a escala regional y local, y además constituyen la base del ejercicio de la gestión del agua subterránea que se esta proponiendo para el acuífero de Neemkheda. Les programmes de développement des bassins versants offrent une occasion de développer des stratégies pour une gestion durable, bien qu' à présent elles restent en grande mesure `le terme source' dans le mécanisme de développement de la ressource en eau. Les conditions hydrogéologiques, la participation de la communauté et l'usage des eaux souterraines sont importants pour le `terme demande' dans les stratégies de gestion des eaux souterraines. L'aquifère de Neemkheda presents des caractéristiques typiques pour un bassin versant dans les régions arides de l'état Madhya Pradesh de l'Inde centrale en ce qui concerne les faible valeurs de la conductivité hydraulique et du coéfficient d'emmagasinement. Il s'agit d'un aquifère phrèatique dont la partie supérieure est constitué par des grès calcaire qui restent sur des grés plus fins. Afin d'essayer le concept de gestion integrée, on a réalisé dans l'aquifère de Neemkheda un captage ayant sept forages qui forment la ressource en eau communale. La stratégie de la gestion systématique du captage est basée sur la relation entre la transmissivité (T), le coéfficient d'emmagasinement (S), donc la diffusivité hydraulique ainsi que sa variation spatiale. Les puits forés dans les zones à grande diffusivité tendent à s'assècher plus vite que ceux creusés dans des zones à faible diffusivité. Le concept de la gestion des eaux souterraines est donc basé sur la distribution spatiale des diffusivités. À partir de ce concept on a développé un programme d'exploitation des forages pendant les saisons sèches. La relation entre les temps d' épuissment locaux et régionaux est determiné par la distribution spatiale de la diffusivitée et forme la base de l'exercice sur la gestion des eaux proposée pour l'aquifère de Neemkheda.

  14. The last stand of the psychocultural cold warriors: military contract research in Vietnam.

    Rohde, Joy

    2011-01-01

    In 1966, the social scientists of the Simulmatics Corporation arrived in Saigon. Tasked by the Pentagon with helping to pacify South Vietnam, they conducted political and social psychological research on Viet Cong defectors, government soldiers, and Vietnamese villagers. This essay argues that Simulmatics's work captures some of the ironies of Cold War social science: its tendency to mask militarization behind the rhetoric of peaceful nation-building, its blurring of data collection and intelligence gathering, and its ambitious dedication to revealing the unseen contents of hearts and minds while remaining ignorant of the historical, cultural, and linguistic contexts in which its subjects lived.

    The evolution of space law over the past 25 years is surveyed, with attention also given to the procedures that were followed. The treaties now in existence are given, as are issues currently before the United Nations Committee on the Peaceful Uses of Outer Space. Projections that were made 25 years ago are discussed in the light of subsequent developments. It is noted that nearly all the technological advances in space activities forecast 25 years ago have come to pass. Various provisions of the 1967 Outer Space Principles Treaty relating to stricture against weapons and the militarization of space are discussed.

    Fundamento. Describir los factores sociodemográficos de pacientes con parálisis de cuerda vocal unilateral (PCVU) a los que se aplica un tratamiento logopédico y  analiza el impacto en la calidad vocal tras la terapia.Metodología. Se incluyeron 47 pacientes con PCVU diagnosticada mediante vídeo-laringoscopia. Todos recibieron intervención logopédica repartida en 15 sesiones y estructurada en tres etapas progresivas. Se instruyó al paciente en técnicas vocales, coordinación fono-respiratoria, control del soplo, tonificación glótica e impostación vocal. Los parámetros incluidos en el estudio antes y después de la terapia fueron: cierre glótico, Voice Handicap Index-10 (VHI-10) para medir la autopercepción de calidad vocal y escala GRABS para la calidad vocal.Resultados. La edad media fue 51 años (rango 20-80), 60% mujeres. La causa quirúrgica fue la más frecuente (72%). El 40% desempeñaban una profesión relacionada con la voz. El tiempo medio desde el diagnóstico hasta el inicio del tratamiento fue 5 meses (2-12). El cierre glótico completo aumentó de34 a 80% (p<0,001), la puntuación en VHI-10 descendió de24,24 a 16,09 puntos (p<0,001) y los valores de GRABS mejoraron en todas las cualidades de la voz (p<0,001). Solo un 8,5% requirió cirugía post-tratamiento.Conclusiones. La terapia de reeducación vocal es eficaz como primera indicación terapéutica en pacientes con PCVU, reservando la medialización con material no reabsorbible o cirugía de tiroplastia a aquéllos con mala evolución. No obstante, es necesario reducir el tiempo que se demora el paciente en llegar ala Unidad de Voz tras el diagnóstico laringoscópico.Palabras clave. Parálisis unilateral de cuerda vocal.

  17. Demographic and quality control parameters of Anastrepha Fraterculus (Diptera: Tephritidae) maintained under artificial rearing

    The integration of the sterile insect technique (SIT) in the management of the South American fruit fly Anastrepha fraterculus (Wiedemann) (Diptera: Tephritidae) is a promising alternative to chemically-based control in those areas where it is sympatric with Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) or other tephritid species for which the SIT is being used. Implementation of the SIT requires the development of a cost effective mass-rearing protocol. In this work, we present demographic and quality control parameters for the A. fraterculus strain reared at the Estacion Experimental Agroindustrial Obispo Colombres, Tucuman, Argentina. Considering the rearing cage as the reproduction unit, we observed that fecundity is optimal during the first 3 weeks after the onset of oviposition. Fertility was constant during this period. During 2003 and 2004, some improvements were made to the existing rearing protocol, which resulted in increased larval viability, pupal weight, and adult emergence. Current weekly egg production is 1 million per week. These eggs are used to maintain the colony and to assess quality parameters. Finally, research needs leading to improved yields and fly quality are discussed. (author) [Spanish] La integracion de la Tecnica del Insecto Esteril (TIE) en el combate integrado de la mosca Sudamericana de la fruta, Anastrepha fraterculus (Wiedemann) (Diptera: Tephritidae), es una alternativa interesante para reemplazar al control quimico en aquellas zonas donde esta especie es simpatrica con Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) u otros tefritidos para los que ya se utiliza la TIE. La implementacion de la TIE requiere del desarrollo de un protocolo de cria masiva que sea costo-efectivo. En este trabajo presentamos parametros demograficos y de control de calidad de la cepa criada en la Estacion Experimental Agroindustrial Obispo Colombres, Tucuman, Argentina. Considerando a la jaula de cria como unidad reproductiva, se observo que la fecundidad es optima durante las tres primeras semanas de iniciada la oviposicion y que la fertilidad se mantiene constante durante ese periodo. Durante 2003-2004 se implementaron mejoras en el protocolo de cria existente lo que resulto en un incremento de la viabilidad larvaria, del peso de pupas y del porcentaje de emergencia de adultos. La produccion actual semanal es de un millon de huevos. Los mismos son utilizados para mantener la colonia y realizar distintos estudios de calidad de esta cepa. Por ultimo, se sugieren necesidades de investigacion para alcanzar mejores rendimientos. (author)

    Sr. Editor: Después de leer con interés el artículo editorial denominado "La academización del primer nivel de atención", escrito por la Dra. Liz Hamui Sutton y el Dr. José Halabe Cherem, queremos comentarle la experiencia que tenemos al respecto en la Facultad de Medicina de la Universidad Nacional Autónoma de México (UNAM). La Secretaría de Enseñanza Clínica e Internado Médico, en el año 1997, introdujo siete unidades del primer nivel de atención para que los educandos pudieran tener la oportunidad de desarrollar sus competencias profesionales en ambientes cuidados, controlados y, además, acordes al perfil de egreso como médicos generales. Paulatinamente se han ido incorporando más, y en la actualidad se cuenta con 31 sedes pertenecientes al Instituto Mexicano del Seguro Social (IMSS) y al Instituto de Seguridad Social y Servicios de los Trabajadores del Estado (ISSSTE). Estos campos clínicos permiten la adquisición y desarrollo de habilidades propias de la propedéutica médica, pues de manera natural se dan las interrelaciones entre estudiantes, profesores y pacientes, adquiriendo aprendizajes significativos, en la teoría y en la práctica clínica. En el año 2015 se supervisaron 15 de estas sedes. En estas visitas se aplicó una encuesta de opinión a los estudiantes y se entrevistó a los alumnos y profesores. En general, los educandos señalaron que se sienten satisfechos con su aprendizaje, que es prácticamente personalizado y de buen nivel académico. También los docentes y las autoridades señalaron sentirse contentos por contar con alumnos que, en su mayoría, eran responsables y comprometidos. PMID:27160629

  19. Comprension de los conceptos de los enlaces ionico y covalente en estudiantes universitarios del primer curso de quimica general

    NASA Astrophysics Data System (ADS)

    Ballesteros Benavides, Maria Elvira

    Para este trabajo utilizamos el estudio de casos cualitativo que se llevo a cabo en una universidad privada de Puerto Rico. Empleamos como unidad de analisis el concepto de enlace quimico, ionico y covalente. Los participantes fueron los estudiantes de la seccion nocturna del curso de Quimica General I. La investigacion se desarrollo por medio de dos entrevistas de persona a persona, observaciones de las expresiones no verbales y la hoja de identificacion de conceptos. Para la triangulacion tomamos en consideracion las preconcepciones erroneas, las concepciones alternativas y el mapa de conceptos de cada participante. Preparamos un mapa de conceptos para el enlace quimico validado por un comite de expertos. Tambien, elaboramos los mapas de conceptos de los participantes que sirvieron para varios propositos: conocer la estructura conceptual, expresar los logros, hacer comparaciones e identificar la presencia de concepciones alternativas. Entre los hallazgos encontramos que todos los participantes poseen conocimiento previo de los enlaces quimicos ionico y covalente y dentro de ese conocimiento existen preconcepciones erroneas mas numerosas para el enlace ionico. Al principio del semestre el 50% de los participantes demostraron tener "carencia fuerte de conceptos" tanto para el enlace ionico como para el covalente. Al finalizar el semestre encontramos en el 40% de los participantes concepciones alternativas tanto para el enlace ionico como para el covalente y el 90% no lograron distinguir un enlace del otro. Nuestras conclusiones fueron que los participantes sin distincion del aprovechamiento academico demostraron tener la tendencia de "carencia fuerte de conceptos" tanto para el enlace ionico como para el covalente, presentaron dificultad al integrar los conceptos de los enlaces quimicos ionico y covalente que se pusieron de manifiesto al dar los ejemplos. Las preconcepciones erroneas contribuyen en el desarrollo de las concepciones alternativas. Ademas, los participantes no lograron diferenciar los dos enlaces quimicos. Esto implica que reflexionemos sobre la necesidad de revisar tanto las competencias cognoscitivas como la forma de ensenar quimica en el salon de clase. Recomendamos indagar y dar importancia al conocimiento previo de los estudiantes, enfatizar la ensenanza de los conceptos y propiciar el aprendizaje con significado.

  8. A new approach to the study of therapeutic work in the transference.

    Pessier, J; Stuart, J

    2000-02-01

    This article proposes a new method for evaluating the effects of therapist and patient work in the transference. Work in the transference is often difficult for the patient, and may show a characteristic pattern of lag between a transference interpretation and its therapeutic effect. To account for this lag, we assessed patient responses to interpretations over the course of entire sessions. The narratives patients told about others, or Relationship Episodes (REs), were used as units of study. In a sample of three consecutive sessions taken from each of three psychodynamic cases, we identified several instances when transference work appeared to have an initial inhibitory effect, but facilitated progress over the course of the entire session. We recommend that to examine the effects of interpretations future studies use longer, more clinically meaningful segments of patient speech than have been used in the past. Dieser Beitrag propagiert eine neue Methode zur Evaluierung der Effekte von bertragungsarbeit durch Therapeut und Patient. Arbeit in der bertragung ist fr den Patienten oftmals schwierig und zeigt hufig eine charakteristisches Muster von zeitlichen Verzgerungen bzgl. bertragungsdeutungen und deren therapeutischen Effekten. Um diese zeitliche Verzgerung zu erklren, untersuchten wir die Reaktionen von Patienten auf derartige Deutungen im Verlauf ganzer Sitzungen. Narrative, in denen die Patienten ber andere berichteten, also Beziehungsepisoden, dienten in dieser Studie als Einheit. In einter Stichprobe dreier aufeinanderfolgender Sitzugnen, die sich auf drei Flle bezogen, identifizierten wir verschiedene Umstnde, unter denen bertragungsarbeit anfnglich einen hemmenden Affekt zu haben schien, letztlich aber den Gesamtverlauf der Sitzung gnstig beeinflussten. Wir empfehlen, in Zukunft die Effekte von bertragungsdeutungen auf der Basis lngerer, klinische sinnvoller Segmente von Patientenuerungen zu untersuchen als dies in der Vergangenheit der Fall war. Cet article propose une nouvelle mthode pour valuer les effets du travail sur le transfert entre thrapeute et patient. Ce travail est souvent difficile pour le patient, et il peut y avoir un pattern caractristique de dlai entre une nterprtation de transfert et son effet thrapeutique. Pour expliquer ce dlai, nous avons valu les rponses des patients des interprtatios au cours de sances entires. C'est les narrations des patients sur d'autres, ou Episodes Relationnels (ERs), qui ont constitu les units de base de cette tude. Dans un chantillon de 3 sances conscutives venant de 3 cas psychodynamiques, nous avons identifi plusieurs moments o le traail sur le transfert semblait avoir un effet inhibitoire initial, mais favorisait le progrs en regardant la sance entire. Nous recommandons pour de futures tudes sur l'effet des interprtations de prendre des segments plus longs et cliniquement significatifs du rcit du patient que ceux utiliss dans le pass. Este artculo propone un nuevo mtodo para evaluar los efectos del trabajo de terapeuta y paciente en la transferencia. El trabajo en la transferencia es, con frecuencia, dificil para el paciente y puede mostrar un lapso caracterstico entre una interpretacin transferencial y sus efectos teraputicos. Para explicar este lapso, hemos evaluado las respuestas del paciente a las interpretaciones a lo largo de sesiones enteras. Como unidad de estudio se usaron las narrativas de los pacientes acerca de otros, o sea, los episodios relacionales (REs). En una muestra de tres sesiones consecutivas tomadas de tres casos psicodinmicos, identificamos varioss casos en los que la trasferencia pareca tener un efecto inicial inhibitorio, aunque se vio que a lo largo de la sesin facilitaba el progreso. Recomendamos que, para examinar los efectos de las interpretaciones, los futuros estudios usen segmentos ms largos y clnicamente ms significativos del habia del paciente que los que se usaron en el pasado.

  9. Trends, prospects and challenges in quantifying flow and transport through fractured rocks

    NASA Astrophysics Data System (ADS)

    Neuman, Shlomo P.

    2005-03-01

    Among the current problems that hydrogeologists face, perhaps there is none as challenging as the characterization of fractured rock (Faybishenko and Benson 2000). This paper discusses issues associated with the quantification of flow and transport through fractured rocks on scales not exceeding those typically associated with single- and multi-well pressure (or flow) and tracer tests. As much of the corresponding literature has focused on fractured crystalline rocks and hard sedimentary rocks such as sandstones, limestones (karst is excluded) and chalk, so by default does this paper. Direct quantification of flow and transport in such rocks is commonly done on the basis of fracture geometric data coupled with pressure (or flow) and tracer tests, which therefore form the main focus. Geological, geophysical and geochemical (including isotope) data are critical for the qualitative conceptualization of flow and transport in fractured rocks, and are being gradually incorporated in quantitative flow and transport models, in ways that this paper unfortunately cannot describe but in passing. The hydrogeology of fractured aquifers and other earth science aspects of fractured rock hydrology merit separate treatments. All evidence suggests that rarely can one model flow and transport in a fractured rock consistently by treating it as a uniform or mildly nonuniform isotropic continuum. Instead, one must generally account for the highly erratic heterogeneity, directional dependence, dual or multicomponent nature and multiscale behavior of fractured rocks. One way is to depict the rock as a network of discrete fractures (with permeable or impermeable matrix blocks) and another as a nonuniform (single, dual or multiple) continuum. A third way is to combine these into a hybrid model of a nonuniform continuum containing a relatively small number of discrete dominant features. In either case the description can be deterministic or stochastic. The paper contains a brief assessment of these trends in light of recent experimental and theoretical findings, ending with a short list of prospects and challenges for the future. Parmis les problèmes aucquels font face les hydrogéologues, il y a celui de la caractérisation des roches fracturées (Faybishenko and Benson, 2000). Cet article discute des solutions associées aux quantifications des écoulements et des transports à travers les roches fracturées à l'échelles des essais de puits et des essais de traçage. Une part importante de la litérature traite des roches cristallines, des roches sédimentaires consolidées telles les grés, les calcaires (exeptés les karsts) et la craie. De fait, cet article traitera la même panoplie de roches. La quantification directe des écoulements et du transport dans de tels milieux est généralement abordée via la géométrie des fractures, les données de pression et de traçage, qui déslors sont les objets principaux de notre étude. La géologie, la géophysique et la géochimie (incluant la géochimie isotopique) sont criticables car elles donnent des informations qualitatives sur l'écoulement et le transport des aquifères fracturés, et son intégrées graduellement dans des modèles qualitatifs. La manière d'intégrer ces données dépasse malheureusement cet article. L'hydrogéologie des aquifères de fractures et les autres sciences de la terre s'intéressant aux roches fracturées méritent des traîtements différents. En toute évidence il est suggéré que rarement un modèle d'écoulement et de transport dans une roche fracturée puisse être traité comme un milieu isotropique continu, uniforme ou moyennement non-uniforme. Par ailleurs, il est admis la dépendance entre la forte hétérogénéité erratique et la variété de natures et de comportements des roches fracturées. Une manière de régler le problème est de considérer le milieu comme un réseau de fractures discrètes (avec une perméabilité de matrice ou de bloc). Une autre est de l'envisager comme un milieu non-uniforme (simple, double ou multiple) continu. Une troisième manière est de combiner ceci dans un modèle hybride d'un milieu non-uniforme, contenant un relativement petit nombre de fractures dominantes et discrètes. Dans d'auters cas la description peut être déterministe ou stochastique. L'article contient un brève apperçu de ces tendances à la lumière d'expériences récentes et de nouvelles théories, et se termine par une courte liste de «challenge» et de priorités pour le futur. Entre los problemas actuales que enfrentan los hidrogeólogos, quizá no hay uno tan desafiante como la caracterización de roca fracturada (Faybishenko y Benson, 2000). Este artículo discute problemas asociados con la cuantificación de flujo y transporte a través de rocas fracturadas en escalas que no exceden las típicas asociadas con presión (o flujo) en un solo pozo o varios pozos y pruebas con trazadores. Debido a que mucha de la literatura del tema se ha enfocado en rocas cristalinas fracturadas y rocas sedimentarias duras tal como areniscas, calizas (excluyendo karst) y creta, también en contumacia lo hace este artículo. La cuantificación directa del flujo y transporte en tales rocas se hace comúnmente en base a datos geométricos de fracturas acoplados con pruebas de presión (o flujo) y trazadores, los cuales por lo tanto constituyen nuestra principal orientación. Datos geológicos, geofísicos y geoquímicos (incluyendo isótopos) son críticos para la conceptualización cuantitativa de flujo y transporte en rocas fracturadas, y se han estado incorporando gradualmente en modelos cuantitativos de flujo y transporte, en formas que desafortunadamente este artículo solo puede describir de paso. La hidrogeología de rocas fracturadas y otros aspectos de ciencia de la tierra de hidrología de rocas fracturadas amerita tratamientos separados. Toda la evidencia sugiere que uno raramente puede modelizar flujo y transporte en una roca consistentemente fracturada si la considera como una unidad continua isotrópica uniforme o poco uniforme. En vez de adoptar este enfoque, uno tiene generalmente que explicar la heterogeneidad altamente errática, dependencia direccional, naturaleza doble o multicomponente y comportamiento multiescalar de las rocas fracturadas. Una manera de lograr esto consiste en considerar que la roca contiene una redde fracturas discretas (con bloques de matriz permeable o impermeable) y otro modo en considerar la roca como una unidad continua no uniforme (sola, doble o múltiple). Un tercer procedimiento consiste en combinar las dos maneras anteriores en un modelo híbrido el cual consiste de un continuo no uniforme conteniendo un número relativamente pequeño de fracturas principalmente discretas. En ambos casos la descripción puede ser determinística o estocástica. El artículo contiene una evaluación breve de estas tendencias en base a descubrimientos recientes teóricos y experimentales, terminando con una lista corta de prospectos y desafíos para el futuro.

  10. The Pliocene Yafo Formation in Israel: Hydrogeologically inert or active?

    NASA Astrophysics Data System (ADS)

    Avisar, D.; Rosenthal, E.; Shulman, H.; Zilberbrand, M.; Flexer, A.; Kronfeld, J.; Ben Avraham, Z.; Fleischer, L.

    For several decades the ``Saqiye beds'' (later renamed Yafo Formation) underlying the Coastal Plain aquifer (Kurkar Group) aquifer of Israel, were regarded as an extremely thick, tectonically undisturbed, and absolutely impervious aquiclude. Following intensive groundwater exploitation from the overlying Kurkar Group aquifer, brackish and saline waters were locally encountered in the lower parts of this aquifer and always at the contact with the underlying Yafo Formation aquiclude. The present study revealed that this aquiclude is not a uniform and impervious rock unit, but rather an alternation of pervious and impervious strata within the Yafo Formation containing highly pressured fluids of different - mostly high - salinities. The permeable beds are at an angular unconformity and in direct contact with the overlying Kurkar Group aquifer. The Yafo Formation and the underlying and overlying rock units are dislocated by numerous fault systems, which facilitate accessibility of brines into the Kurkar Group aquifer. The mobilization of the saline fluids and their injection into the Kurkar Group aquifer could be due either to diffusion of saline fluids occurring in the permeable horizons of the Petah Tiqva Member through the clays of the Yafo Formation or to their upconing following intensive pumping in the Coastal Plain aquifer. It could have also been caused by up-dip movement of saline water as the result of overpressure generated by major accumulation of gas in the permeable horizons. Another possible mechanism could be hydraulic contact with pressurized brines up-flowing along fault zones from deep-seated Jurassic or Cretaceous reservoirs. The squeezing of saline interstitial water from the clays of the Yafo Formation into the overlying Kurkar Group aquifer, is of secondary importance for groundwater salinization (its input is comparable with salt input from rain). Depuis longtemps, les «couches de Saqiye», nommées maintenant formation de Yafo, constituant le mur de l'aquifère côtier (série de Kurkar) d'Israël, ont été considérées comme un ensemble extrêmement épais, sans déformation tectonique et totalement imperméable. À la suite de l'exploitation intensive de l'eau souterraine de l'aquifère sus-jacent de la série de Kurkar, des eaux salées et des saumures sont rencontrées occasionnellement dans les parties les plus profondes de cet aquifère et toujours au contact de l'imperméable sous-jacent de la formation de Yafo. Cette étude a révélé que cet imperméable n'est pas une unité géologique uniforme et imperméable, mais qu'il s'agit plutôt d'une alternance de couches perméables et imperméables dans la formation de Yafo contenant des fluides sous des pressions fortes avec des salinités différentes (?) et en général élevées (?). Les niveaux perméables sont en discordance angulaire et en contact direct avec l'aquifère sus-jacent de la série de Kurkar. La formation de Yafo et les unités géologiques situées dessous et dessus sont disloquées par de nombreuses systèmes de failles, qui facilitent le passage des saumures dans l'aquifère de la série de Kurkar. La mobilisation des fluides salins et leur injection dans l'aquifère de Kurkar pourraient être dues soit à la diffusion des fluides salins dans les horizons perméables du Petah Tiqva au travers des argiles de la formation de Yafo, soit leur remontée par upconing sous l'effet de pompages intensifs dans l'aquifère de la plaine côtière. Il peut aussi être causé par la remontée des eaux salines selon le pendage sous l'effet d'une surpression provoquée par une accumulation considérable de gaz dans les horizons imperméables. Un autre mécanisme possible pourrait être un contact hydraulique avec des saumures sous pression, remontant le long des zones de faille depuis des réservoirs profonds jurassiques ou crétacés. L'expulsion d'eau saline interstitielle des argiles de la formation de Yafo dans l'aquifère de Kurkar est d'importance secondaire pour la salinisation de l'eau souterraine cet apport est comparable à celui de sels par les pluies. Durante décadas, las ``Saqiyebeds'' (rebautizadas como Formación Yafo) que se sitúan bajo el acuífero Costero (Grupo Kurkar) de Israel fueron consideradas como un acuicludo extremadamente potente, tectónicamente inalterado y totalmente impermeable. Como resultado de la explotación intensiva del Grupo Kurkar, se produjo la mezcla de aguas salobres y salinas en la zona inferior de dicho acuífero y siempre en el contacto con el acuicludo subyaciente de la Formación Yafo. Este estudio reveló que el acuicludo no es una unidad rocosa uniforme e impermeable, sino que consiste en una alternancia de estratos permeables e impermeables dentro de la Formación Yafo, que contiene fluidos a alta presión de salinidades diferentes pero generalmente elevadas. Las capas permeables se hallan en inconformidad angular y en contacto directo con el acuífero superior del Grupo Kurkar. La Formación Yafo y las unidades rocosas infra- y suprayacentes están dislocadas por numerosos sistemas de fallas, lo que facilita el acceso de las salmueras al acuífero del Grupo Kurkar. Los fluidos de los horizontes permeables del Miembro Petah Tiqva a través de las arcillas de la Formación Yafo o hacia el ascenso de los domos salinos en respuesta a la extracción intensiva en el acuífero del Llano Costero. Podría también haber sido causado por el movimiento a favor del buzamiento de las aguas salinas como resultado de la sobrepresión generada por una acumulación mayor de gas en los horizontes permeables. Otro posible mecanismo podría basarse en el contacto hidráulico con salmueras presurizadas, que fluyen hacia arriba a favor de zonas de falla desde los reservorios profundos del Jurásico o del Cretácico. La extracción de agua salina intersticial desde las arcillas de la Formación Yafo hacia el acuífero superior del Grupo Kurkar es de importancia secundaria para la salinización de las aguas subterráneas, ya que su aportación es comparable a la procedente del agua de lluvia.

  11. Assessment of hydraulic properties of sedimentary and volcanic aquifer systems under arid conditions in the Republic of Djibouti (Horn of Africa)

    NASA Astrophysics Data System (ADS)

    Jalludin, Mohamed; Razack, Moumtaz

    The Republic of Djibouti (23,000 km2 500,000 inhabitants), located within the Horn of Africa, undergoes an arid climate with an average annual rainfall less than 150 mm. Water resources are provided up to 98% by groundwater. Two types of aquifers are encountered: volcanic and sedimentary aquifers. This paper focuses on the assessment of their hydraulic properties, which is necessary for future tasks regarding the management of these aquifers. To this end, a data base consisting of all available pumping test data obtained since the 1960s was compiled. Pumping tests have been interpreted to determine transmissivity. Solely for volcanic aquifers, transmissivity also has been estimated through an empirical relationship using specific capacity corrected for turbulent well losses. The transmissivity of each type of aquifer can span up to four orders of magnitude, pointing out their strong heterogeneity. For the various volcanic rocks, the younger the rock, the higher the transmissivity. The transmissivity of volcanic rocks has therefore decreased in the course of geological time. At present, a much better understanding of the hydraulic properties of these complex aquifers has been obtained, which should enable optimal management of their groundwater resources through the use of numerical modeling. La République de Djibouti (23,000 km2 500,000 habitants), située dans la Corne de l'Afrique, subit un climat aride avec une pluviométrie moyenne annuelle inférieure à 150 mm. Les ressources en eau sont fournies à plus de 98% par les eaux souterraines contenues dans des aquifères sédimentaires ou volcaniques. Cet article a pour objectif l'évaluation des propriétés hydrauliques de ces aquifères, étape indispensable pour entreprendre par la suite des études en vue de la gestion de ces aquifères. Une base rassemblant les données d'essais par pompage disponibles depuis les années Soixante a d'abord été établie. Les essais par pompage ont été interprétés pour déduire la transmissivité. 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 la roca. La permeabilidad de las rocas volcánicas ha evolucionado por tanto con el tiempo geológico. Actualmente, se posee un mayor conocimiento sobre las propiedades hidráulicas de estos acuíferos complejos, de manera que se puede hacer una gestión óptima de sus recursos hídricos subterráneos con la utilización de modelos numéricos.

  12. Scheme for development of monitoring networks for springs in Bavaria, Germany

    NASA Astrophysics Data System (ADS)

    Bender, Steffen; Einsiedl, Florian; Wohnlich, Stefan

    2001-03-01

    The present groundwater monitoring network in Bavaria consists mostly of wells and only a small number of natural groundwater springs, all of which are analyzed for mainly the common physical and chemical constituents in groundwater. In order to develop a long-term groundwater management plan for all the groundwater resources of Bavaria, the Bavarian State Office for Water Management intends to establish a separate spring-monitoring network throughout the 11 groundwater provinces of the state. As a first step, significant physicochemical parameters that show considerable annual fluctuation (after monitoring 1-3 years) were determined at 21 springs or spring systems to create a basic data set to guide future monitoring. A selection procedure was developed around four parameters: (1) geological units, which includes the principal aquifers; (2) rate of spring discharge; (3) land utilization within a catchment; and (4) approximate size of the subterranean catchment. However, in the initial phase of the study, only the first three parameters were investigated. These parameters established a matrix for evaluating each groundwater region of Bavaria to aid in the selection of additional springs for the proposed monitoring network. Résumé. Le réseau actuel de surveillance des eaux souterraines en Bavière consiste surtout en des puits avec seulement un petit nombre de sources, tous analysés pour l'essentiel pour les composants courants physiques et chimiques des eaux souterraines. Afin de développer un plan de gestion à long terme des eaux souterraines de la Bavière, l'Office bavarois pour la gestion de l'eau cherche à mettre en place un réseau séparé de surveillance des sources dans les onze provinces hydrogéologiques du lander. Dans un premier temps, les paramètres physico-chimiques significatifs qui présentent des variations annuelles considérables, après 1 à 3 ans de surveillance, ont été déterminés à 21 sources ou groupes de sources pour constituer un jeu de données de base pour guider la future surveillance. Une procédure de sélection a été développée autour de quatre paramètres: (1) les unités géologiques, comprenant les principaux aquifères, (2) le débit des sources, (3) l'occupation du sol dans le bassin, et (4) la dimension approximative du bassin d'alimentation souterrain. Toutefois, dans la phase initiale de l'étude, seuls les trois premiers paramètres ont été étudiés. Ces paramètres constituent une matrice d'évaluation de chaque région hydrogéologique de Bavière pour aider à la sélection de sources supplémentaires destinées au réseau de surveillance proposé. Resumen. La red de muestreo actual de aguas subterráneas en Bavaria (Alemania) está formada sobre todo por pozos, mientras que apenas hay unos pocos manantiales naturales. Los análisis incluyen, principalmente, los parámetros físico-químicos habituales. Con el objeto de desarrollar un plan de gestión de las aguas subterráneas en Bavaria a largo plazo, el Consejo del Estado para la Gestión del Agua pretende establecer una red de muestreo de manantiales diferenciada en las once regiones en que se divide el estado desde el punto de vista de las aguas subterráneas. Como primer paso, se determinaron los parámetros físico-químicos significativos que mostraban una fluctuación anual considerable (tras un muestreo de 1 a 3 años), con la finalidad de crear una base de datos elemental que canalizara los muestreos futuros. Se desarrolló un procedimiento de selección con base en cuatro parámetros: (1) unidades geológicas y acuíferos principales; (2) caudal del manantial; (3) uso del suelo dentro de la cuenca; y (4) tamaño aproximado de la zona de captación subterránea. Sin embargo, sólo se investigaron los tres primeros parámetros durante la fase inicial del estudio. Con ellos, se estableció una matriz para evaluar cada zona acuífera dentro de Bavaria y ayudar en la inclusión de otros manantiales en la red de muestro propuesta.

  13. Hydraulic properties and scale effects investigation in regional rock aquifers, south-western Quebec, Canada

    NASA Astrophysics Data System (ADS)

    Nastev, M.; Savard, M. M.; Lapcevic, P.; Lefebvre, R.; Martel, R.

    This paper reports on the characterization of hydraulic properties of regional rock aquifers carried out within a groundwater resources assessment project in the St. Lawrence Lowlands of south-western Quebec. To understand the aquifer behavior at both the fracture level and at field scale, hydraulic investigations were carried out using various aquifer tests. The groundwater flow at the local scale is controlled mostly by the fracture system. Results of the constant-head injection tests show a weak decreasing trend of hydraulic conductivity with depth indicating that a major part of the groundwater flow occurs in the first meters of the rock sequence. At the regional scale, the equivalent porous media approach is applicable. The hydraulic conductivity measurements were correlated to the scale of the aquifer tests expressed with the investigated aquifer volume. A simple interpolation procedure for the hydraulic conductivity field was developed based on the distance between field measurements and the tested aquifer volumes. The regional distribution of the hydraulic conductivity for the major fractured aquifer units indicates that dolostone is the most permeable whereas sandstone and crystalline rocks are the least permeable units. Este artículo trata de la caracterización de las propiedades hidráulicas en acuíferos regionales rocosos, la cual se llevó a cabo dentro del proyecto de evaluación de los recursos de agua subterránea en St. Lawrence Lowlands al suroeste de Quebec. Para entender el comportamiento del acuífero tanto a nivel de fractura como a escala del campo, se ejecutaron investigaciones hidráulicas usando varias pruebas de acuífero. El flujo del agua subterránea a escala local está controlado principalmente por el sistema de fracturas. Los resultados de las pruebas de inyección con cabeza constante muestran una tendencia decreciente débil de la conductividad hidráulica con la profundidad, indicando que la mayor parte del flujo de agua subterránea sucede en los primeros metros de la secuencia rocosa. A escala regional se puede aplicar la aproximación equivalente de medios porosos. Las medidas de la conductividad hidrálica fueron comparadas con la escala de las pruebas del acuífero, expresadas con el volumen investigado del acuífero. Se desarrolló un proceso de interpolación simple para la conductividad hidráulica de campo, con base en la distancia entre las medidas de campo y los volúmenes probados del acuífero. La distribución regional de la conductividad hidráulica, para las unidades acuíferas fracturadas mayores, indica que la dolomita es más permeable mientras que la arenisca y las rocas cristalinas son las unidades menos permeables. L'article présente les propriétés hydrauliques d'un aquifère régional rocheux qui ont été mesurées dans le cadre d'un projet concernant l'estimation de la ressource en eau de la plaine de St. Lawrence située dans la partie sud-ouest de Quebec. Affin de comprendre le comportement de l'aquifère tant à l'échelle de fracture qu'à l'échelle régionale on a mené des investigations hydrauliques en utilisant des essais differents. À l'échelle locale l'écoulement est déterminé en principal par le système des fractures. Les résultats des essais d'injection au niveau constant ont montré une tendence de décroissance de la conductivité hydraulique avec la profondeur ce qui indique que l'écoulement ait lieu en principal dans les premiers mètres de la structure rocheuse. À l'échelle règionale on peut appliquer l'approche de milieux poreux equivalent. Les mesures de conductivité hydraulique ont été corrélées avec l'échelle des essais de pompage exprimée en termes de volume investigué de l'aquifère. On a mis au point une méthode simple d'interpolation pour le champ de la conductivité hydraulique basée sur la distance entre les essais in situ et les volume investigués de l'aquifère. La distribution règionale de la conductivité hydraulique montre que pour la majorité des unités de roche fracturé les plus perméable sont les roches dolomitiques alors que les grés et les roches cristalines presentent la plus faible perméabilité.

    The unprecedented success of the Movember campaign in raising money for, and awareness of, prostate cancer (PCa) brings with it a novel opportunity to consider how masculinity and men's health can connect. In this essay we first detail the history of some less fruitful endeavors for advancing PCa awareness that played on masculine stereotypes. We then consider how Movember's moustache motif has succeeded. Included are commentaries about why the strongly masculine motifs of combat, loyalty, and aggression couched in military language were not successful when used to promote concern about men's health. Movember in contrast succeeds by focusing on a way that men can express their individuality without resorting to overt acts or signs of aggression or militarism. PMID:25024274

    How may one exorcise the twin demons that plague human society: irrational beliefs derived from faith, and of violence and militarism? The hope for a better future goes something like this: if a society is convinced that it must develop science because it wants technology, then the teaching of science is allowed even in societies where the scientific method is not wholly welcome. Therefore, because critical inquiry is its basic tool, science can be a Trojan Horse that silently subverts and ultimately helps to win the battle for secular humanism and peace. To what extent are such hopes realistic? I shall draw upon my experiences in Pakistan to argue that good science teaching may indeed be our best bet. The battle for a peaceful, non-nuclear world will also require both a greater public understanding of science, and a commitment to work against prejudices induced by religious faith and nationhood. )

    In, this paper, I explore the need for particular types of interdisciplinarity, which I refer to as technical heteroglossia, in the face of neoliberal political and economic disenfranchisement. I examine the case of a group of medics (EMTs, nurses, and lay medical practitioners) known as street medics and their efforts to provide a working set of medical protocols for protesters, victims of natural disasters, and, more generally, communities resisting neoliberalism, militarism, and corporate power. To function, this network has had to explicitly embrace multiple medical traditions: allopathic (sometimes called Western), Chinese, herbalist, naturopathic, etc. Being able to speak within multiple traditions (medical heteroglossia) is deeply valued. I also recount the history of the medics and discuss at length the contextual forces that pull medics in different directions: allopathic medicine and more varied and unorthodox practices.

    Worldwide the greatest effects on the health of individuals and populations results from environmental degradation and social injustice, operating in consort. This paper describes the national and global causes and health consequences of these phenomena. Causes include overpopulation, pollution, deforestation, global warming, unsustainable agricultural and fishing practices, overconsumption, maldistribution of wealth, the rise of the corporation, the Third World debt crisis, and militarization and wars. Consequences include increased poverty, overcrowding, famine, weather extremes, species loss, acute and chronic medical illnesses, war and human rights abuses, and an increasingly unstable global situation that portends Malthusian chaos and disaster. Because of their scientific training, and due to their privileged socioeconomic status, physicians are in a unique position to recognize these phenomena and to act at all levels, from interactions with their patients, to volunteerism, to service and intervention in areas of great need, to direct political activism and involvement. Specific suggestions for action are discussed. PMID:12570975

    1988-01-01

    The Advanced Composite Airframe Program (ACAP) was undertaken to demonstrate the advantages of the application of advanced composite materials and structural design concepts to the airframe structure on helicopters designed to stringent military requirements. The primary goals of the program were the reduction of airframe production costs and airframe weight by 17 and 22 percent respectively. The ACAP effort consisted of a preliminary design phase, detail design, and design support testing, full-scale fabrication, laboratory testing, and a ground/flight test demonstration. Since the completion of the flight test demonstration programs follow-on efforts were initiated to more fully evaluate a variety of military characteristics of the composite airframe structures developed under the original ACAP advanced development contracts. An overview of the ACAP program is provided and some of the design features, design support testing, manufacturing approaches, and the results of the flight test evaluation, as well as, an overview of Militarization Test and Evaluation efforts are described.

  20. Reagan's energy war: can deregulation and the Pentagon save the nuclear industry

    Feeney, A.

    1981-11-01

    Mr. Feeney feels that Administration energy policies claiming to protect democracy and reduce government interference will transfer money and political control from the people to the energy corporations and the Pentagon. Critics deplore the hard-path approach of downgrading conservation and solar energy in favor of nuclear energy, which some see as setting the stage for a nuclear war in this decade. They see the plan to abolish DOE as providing an opportunity to bail out the nuclear industry, bury environmental and alternative energy research, and block regulations. Critics question why Reagan's devotion to the free market is not applied to the nuclear industry, although they disagree on the linkage with nuclear weapons of new fuel cycle proposals and the use of national security to solve the waste disposal problem by nationalizing and militarizing the fuel cycle.

    War and terrorism, which are inseparable, cause death and disability, profound psychological damage, environmental destruction, disruption of the health infrastructure, refugee crises, and increased interpersonal, self-directed and collective violence. Weapons systems such as weapons of mass destruction and landmines have their own specific devastating effects. Preparation for war and preparedness for terrorism bring constraints on civil liberties and human rights, increase militarism, and divert resources from health care and from other needed services. War and terrorism may be best prevented through addressing their causes, which include limited resources, injustice, poverty and ethnic and religious enmity, and through strengthening the United Nations and the treaties controlling specific weapons systems, particularly weapons of mass destruction. In particular, the United States should cease its interference in the internal affairs of other nations and its advocacy of unilateral pre-emptive war. PMID:18771191

    DRDC Valcartier recently completed the development of the CATSI EDM (Compact Atmospheric Sounding Interferometer Engineering Development Model) for the Canadian Forces (CF). It is a militarized sensor designed to meet the needs of the CF in the development of area surveillance capabilities for the detection and identification of chemical Warfare Agents (CWA) and toxic industrial chemicals (TIC). CATSI EDM is a passive infrared double-beam Fourier spectrometer system designed for real-time stand-off detection and identification of chemical vapours at distances up to 5 km. It is based on the successful passive differential detection technology. This technique known as optical subtraction, results in a target gas spectrum which is almost free of background, thus making possible detection of weak infrared emission in strong background emission. This paper summarizes the system requirements, achievements, hardware and software characteristics and test results.

  3. The General Age of Leadership: Older-Looking Presidential Candidates Win Elections during War

    2012-01-01

    As nation-state leaders age they increasingly engage in inter-state militarized disputes yet in industrialized societies a steady decrease in testosterone associated with aging is observed – which suggests a decrease in dominance behavior. The current paper points out that from modern societies to Old World monkeys increasing both in age and social status encourages dominant strategies to maintain acquired rank. Moreover, it is argued this consistency has shaped an implicit prototype causing followers to associate older age with dominance leadership. It is shown that (i) faces of older leaders are preferred during intergroup conflict and (ii) morphing U.S. Presidential candidates to appear older or younger has an overriding effect on actual election outcomes. This indicates that democratic voting can be systematically adjusted by activating innate biases. These findings appear to create a new line of research regarding the biology of leadership and contextual cues of age. PMID:22649504

  4. Books vs bombs? Humanitarian development and the narrative of terror in Northern Pakistan.

    Ali, Nosheen

    2010-01-01

    This article examines the role of humanitarian discourse and development in reconfiguring the contemporary culture of empire and its war on terror. It takes as its point of entry the immensely popular biographical tale, Three Cups of Tea, which details how the American mountaineer Greg Mortenson has struggled to counter terrorism in Northern Pakistan through the creation of schools. Even as this text appears to provide a self-critical and humane perspective on terrorism, the article argues that it constructs a misleading narrative of terror in which the realities of Northern Pakistan and Muslim life-worlds are distorted through simplistic tropes of ignorance, backwardness and extremism, while histories of US geopolitics and violence are erased. The text has further facilitated the emergence of a participatory militarism, whereby humanitarian work helps to reinvent the military as a culturally sensitive and caring institution in order to justify and service the project of empire.

    In 2009 the American Public Health Association approved the policy statement, “The Role of Public Health Practitioners, Academics, and Advocates in Relation to Armed Conflict and War.” Despite the known health effects of war, the development of competencies to prevent war has received little attention. Public health’s ethical principles of practice prioritize addressing the fundamental causes of disease and adverse health outcomes. A working group grew out of the American Public Health Association’s Peace Caucus to build upon the 2009 policy by proposing competencies to understand and prevent the political, economic, social, and cultural determinants of war, particularly militarism. The working group recommends that schools of public health and public health organizations incorporate these competencies into professional preparation programs, research, and advocacy.

    Warfare has long been associated with traumatic brain injury (TBI) in militarized zones. Common forms of TBI can be caused by a physical insult to the head-brain or by the effects of a high velocity blast shock wave generated by the detonation of an explosive device. While both forms of trauma are distinctly different regarding the mechanism of trauma induction, there are striking similarities in the cognitive and emotional status of survivors. Presently, proven effective therapeutics for the treatment of either form of TBI are unavailable. To be able to develop efficacious therapies, studies involving animal models of physical- and blast-TBI are required to identify possible novel or existing medicines that may be of value in the management of clinical events. We examined indices of cognition and anxiety-like behavior and the hippocampal gene transcriptome of mice subjected to both forms of TBI. We identified common behavioral deficits and gene expression regulations, in addition to unique injury-specific forms of gene regulation. Molecular pathways presented a pattern similar to that seen in gene expression. Interestingly, pathways connected to Alzheimer’s disease displayed a markedly different form of regulation depending on the type of TBI. While these data highlight similarities in behavioral outcomes after trauma, the divergence in hippocampal transcriptome observed between models suggests that, at the molecular level, the TBIs are quite different. These models may provide tools to help define therapeutic approaches for the treatment of physical- and blast-TBIs. Based upon observations of increasing numbers of personnel displaying TBI related emotional and behavioral changes in militarized zones, the development of efficacious therapies will become a national if not a global priority.

  9. Modern pentathlon and the First World War: when athletes and soldiers met to practise martial manliness.

    PubMed

    Heck, Sandra

    2011-01-01

    In the nationalistic atmosphere of the early twentieth century, a nurturing medium for sports practising martial manliness abounded throughout Europe. This framework supported the invention of a new multi-disciplinary sport, aided by Baron Pierre de Coubertin himself: modern pentathlon. Though the idea of a new form of pentathlon was already born in 1894, it took 30 years, until Paris 1924, to establish modern pentathlon within the Olympic Games. This study is concerned with the reasons for that delay. It will be assessed whether the active military preparations around the First World War and the contemporary image of masculinity had a decisive influence on the early history of modern pentathlon. By including historical documents from the IOC archives in Lausanne, Switzerland, the research office for military history in Potsdam, Germany, and the LA84 Foundation in Los Angeles, USA, as well as literature on gender, military sport and Olympic history, this study offers an entirely new view on the early history of a sport that was born in an atmosphere of glorifying manliness and apparent militarism. The history of modern pentathlon thereby provides a particularly appropriate area for the analysis of connections between sport, militarism and masculinity. It was not by chance that the implementation of a combined sport, which included besides swimming and running the three military disciplines of shooting, fencing and horse riding, arose in a pre-war context. Though in 1912 the Great War had not yet begun, the awareness of an upcoming battle was rising and led to a higher attention to Coubertin's almost forgotten assumption of a new sport. In 1924 the advantages were finally admitted on two sides: the army recruited modern pentathletes as future military officers; the sports community appointed skilled officers as successful competitors. Thus the lobby for an Olympic recognition of modern pentathlon was found. PMID:21714204

    Al-Awadi, E.; Mukhopadhyay, A.; Al-Senafy, M. N.

    The Dammam Formation of Middle Eocene age is one of the major aquifers containing useable brackish water in Kuwait. Apart from the paleokarst zone at the top, the Dammam Formation in Kuwait consists of 150-200m of dolomitized limestone that is subdivided into three members, on the basis of lithology and biofacies. The upper member consists of friable chalky dolomicrite and dolomite. The middle member is mainly laminated biomicrite and biodolomicrite. The lower member is nummulitic limestone with interlayered shale toward the base. Geophysical markers conform to these subdivisions. Core analyses indicate that the upper member is the most porous and permeable of the three units, as confirmed by the distribution of lost-circulation zones. The quality of water in the aquifer deteriorates toward the north and east. A potentiometric-head difference exists between the Dammam Formation and the unconformably overlying Kuwait Group; this difference is maintained by the presence of an intervening aquitard. Résumé La formation de Damman, d'âge Éocène moyen, est l'un des principaux aquifères du Koweit, contenant de l'eau saumâtre utilisable. A part dans sa partie supérieure où existe un paléokarst, la formation de Damman au Koweit est constituée par 150 à 200m de calcaires dolomitisés, divisés en trois unités sur la base de leur lithologie et de biofaciès. L'unité supérieure est formée d'une dolomicrite crayeuse et friable et d'une dolomie. L'unité médiane est pour l'essentiel une biomicrite laminée et une biodolomicrite. L'unité inférieure est un calcaire nummulitique avec des intercalations argileuses vers la base. Les marqueurs géophysiques sont conformes à ces subdivisions. Les analyses de carottes montrent que l'unité supérieure est la plus poreuse et la plus perméable des trois. La répartition des zones d'écoulement souterrain confirment ces données. La qualité de l'eau dans l'aquifère se dégrade en direction du nord et de l'est. Une différence de niveau piézométrique est observée entre la formation de Damman et le groupe de Koweit qui la recouvre en discordance; cette différence est due à la présence d'un niveau imperméable qui la maintient captive. Resumen La Formación Damman, del Eoceno Medio, es uno de los mayores acuíferos de agua salobre aprovechable en Kuwait.

La parte superior está formada por dolomicrita yesífera friable y dolomita. La parte central es básicamente biomicrita laminada y biodolomicrita. La inferior es caliza nummulítica, con intercalaciones de pizarra en la base. Los marcadores geofísicos reflejan claramente estas subdivisiones. Los análisis de testigos revelan que la parte superior es la más porosa y permeable de las tres unidades. Esto queda confirmado con la distribución de zonas de circulación perdidas. La calidad del agua en el acuífero se deteriora hacia el norte y el este. Sobre la Formación Damman, y de manera no conforme, suprayace otra formación, que se conoce como Grupo Kuwaití. Existe una diferencia de niveles piezométricos entre ambas formaciones, la cual se mantiene por la presencia de una capa semiconfinante.

  11. Aquifer/aquitard interfaces: mixing zones that enhance biogeochemical reactions

    NASA Astrophysics Data System (ADS)

    McMahon, P. B.

    2001-01-01

    Several important biogeochemical reactions are known to occur near the interface between aquifer and aquitard sediments. These reactions include O2 reduction; denitrification; and Fe3+, SO42-, and CO2 (methanogenesis) reduction. In some settings, these reactions occur on the aquitard side of the interface as electron acceptors move from the aquifer into the electron-donor-enriched aquitard. In other settings, these reactions occur on the aquifer side of the interface as electron donors move from the aquitard into the electron-acceptor-enriched, or microorganism-enriched, aquifer. Thus, the aquifer/aquitard interface represents a mixing zone capable of supporting greater microbial activity than either hydrogeologic unit alone. The extent to which biogeochemical reactions proceed in the mixing zone and the width of the mixing zone depend on several factors, including the abundance and solubility of electron acceptors and donors on either side of the interface and the rate at which electron acceptors and donors react and move across the interface. Biogeochemical reactions near the aquifer/aquitard interface can have a substantial influence on the chemistry of water in aquifers and on the chemistry of sediments near the interface. Résumé. Il se produit au voisinage de l'interface entre les aquifères et les imperméables plusieurs réactions biogéochimiques importantes. Il s'agit des réactions de réduction de l'oxygène, de la dénitrification et de la réduction de Fe3+, SO42- et CO2 (méthanogenèse). Dans certaines situations, ces réactions se produisent du côté imperméable de l'interface, avec des accepteurs d'électrons qui vont de l'aquifère vers l'imperméable riche en donneurs d'électrons. Dans d'autres situations, ces réactions se produisent du côté aquifère de l'interface, avec des donneurs d'électrons qui se déplacent de l'imperméable vers l'aquifère riche en accepteurs d'électrons ou en microorganismes. Ainsi, l'interface aquifère/imperméable constitue une zone de mélange capable de supporter une plus grande activité microbienne que chacune des deux unités hydrogéologiques seules. L'extension des réactions biogéochimiques dans la zone de mélange et la largeur de cette zone dépendent de plusieurs facteurs, dont l'abondance et la solubilité des accepteurs et des donneurs d'électrons de chaque côté de l'interface, et le taux de réaction et de déplacement des accepteurs et des donneurs d'électrons au travers de cette interface. Les réactions biogéochimiques au voisinage de l'interface aquifère/imperméable peuvent avoir une influence appréciable sur le chimisme de l'eau des aquifères et sur celui des sédiments au niveau de l'interface. Resúmen. Es conocido que varias reacciones biogeoquímicas de importancia pueden tener lugar cerca de la interfaz entre los sedimentos de un acuífero y de un acuitardo. Entre ellas, destaca la reducción del O2, la denitrificación, y la reducción del Fe+3, SO4-2 y CO2 (metanogénesis). En algunos casos, estas reacciones se producen en la región cercana al acuitardo, ya que los dadores de electrones se mueven desde éste hacia el acuífero, el cual está enriquecido en aceptores de electrones o en microorganismos. Así, la interfaz acuífero/acuitardo constituye una zona de mezcla que es capaz de sustentar una actividad microbiana mayor que cualquier unidad hidrogeológica por sí misma. El alcance de las reacciones biogeoquímicas en la zona de mezcla y el ancho de esta zona de mezcla depende de varios factores, como la abundancia y la solubilidad de los aceptores y dadores de electrones en ambas caras de la interfaz y la velocidad a la que los aceptores y dadores de electrones reaccionan y se mueven a través de la interfaz. Las reacciones biogeoquímicas cerca de la interfaz acuífero/acuitardo pueden tener una influencia substancial en la hidroquímica de los acuíferos y en la química de los sedimentos cerca de la superficie.

  12. On matrix diffusion: formulations, solution methods and qualitative effects

    NASA Astrophysics Data System (ADS)

    Carrera, Jesús; Sánchez-Vila, Xavier; Benet, Inmaculada; Medina, Agustín; Galarza, Germán; Guimerà, Jordi

    Matrix diffusion has become widely recognized as an important transport mechanism. Unfortunately, accounting for matrix diffusion complicates solute-transport simulations. This problem has led to simplified formulations, partly motivated by the solution method. As a result, some confusion has been generated about how to properly pose the problem. One of the objectives of this work is to find some unity among existing formulations and solution methods. In doing so, some asymptotic properties of matrix diffusion are derived. Specifically, early-time behavior (short tests) depends only on φm2RmDm / Lm2, whereas late-time behavior (long tracer tests) depends only on φmRm, and not on matrix diffusion coefficient or block size and shape. The latter is always true for mean arrival time. These properties help in: (a) analyzing the qualitative behavior of matrix diffusion; (b) explaining one paradox of solute transport through fractured rocks (the apparent dependence of porosity on travel time); (c) discriminating between matrix diffusion and other problems (such as kinetic sorption or heterogeneity); and (d) describing identifiability problems and ways to overcome them. RésuméLa diffusion matricielle est un phénomène reconnu maintenant comme un mécanisme de transport important. Malheureusement, la prise en compte de la diffusion matricielle complique la simulation du transport de soluté. Ce problème a conduit à des formulations simplifiées, en partie à cause de la méthode de résolution. Il s'en est suivi une certaine confusion sur la façon de poser correctement le problème. L'un des objectifs de ce travail est de trouver une certaine unité parmi les formulations et les méthodes de résolution. C'est ainsi que certaines propriétés asymptotiques de la diffusion matricielle ont été dérivées. En particulier, le comportement à l'origine (expériences de traçage courtes) dépend uniquement du terme φm2RmDm / Lm2, alors que le comportement à long terme (traçages de longue durée) ne dépend que de φmRm, et non pas du coefficient de diffusion matricielle ou de la forme et de la taille des blocs. Ceci est toujours vrai pour le temps moyen d'arrivée. Ces propriétés permettent: (a) d'analyser le comportement de la diffusion matricielle; (b) d'expliquer un paradoxe du transport de soluté dans les roches fracturées (la dépendance apparente entre la porosité et le temps de transit); (c) de faire la distinction entre la diffusion matricielle et d'autres problèmes, tels que la sorption cinétique ou l'hétérogénéité et (d) de décrire les problèmes d'identification et les façons de les résoudre. Resumen La difusión en la matriz está reconocida en la actualidad como un importante mecanismo de transporte de solutos. Desgraciadamente, tener en cuenta este proceso complica las simulaciones de transporte. Esto ha llevado a una serie de formulaciones simplificadas, motivadas en parte por el propio método de solución. Como resultado, se ha producido cierta confusión respecto a cuál es la manera adecuada de formular el problema. Uno de los objetivos de este trabajo es encontrar una cierta unidad entre las formulaciones existentes y los métodos de solución, lo que conduce a algunas propiedades asintóticas de la difusión en la matriz; específicamente, se comprueba que el comportamiento para tiempos cortos depende únicamente del parámetro φm2RmDm / Lm2, mientras que el de tiempos largos depende sólo de φmRm, y no del coeficiente de difusión en la matriz o del tamaño o forma del bloque. Esto último también es cierto, en todos los casos, respecto al tiempo medio de llegada (definido como el valor esperado de la distribución de tiempos de llegada). Estas propiedades son útiles para: (a) analizar el comportamiento cualitativo de la difusión en la matriz; (b) explicar una de las paradojas del transporte de solutos en medios fracturados, la aparente dependencia entre porosidad y tiempo de llegada; (c) discriminar entre difusión en la matriz y otros problemas, como las reacciones con cinética química o la heterogeneidad; y (d) describir problemas de identificabilidad y posibles modos de resolverlos.

    The concept of "Cosmography" is in disuse since the 80s of the last century, but the astronomical themes previously discussed in the school subjects of Geography and Cosmography remain in current textbooks. The use of term "Cosmography" was rescued in this research, and the study of its re-signification prompted the appearance of the term Geographic Cosmography. The Geographic Cosmography is a field of studies of the Geography, whose set of knowledge and skills is predominantly scholar. It studies the interface between terrestrial and celestial knowledge, and assigns a geographic significance to them. It examines human and natural relationships with Sidereal Space and its consequences for society and nature. O conceito de "Cosmografia" está em desuso desde os anos 80 do século XX, mas os temas astronômicos anteriormente abordados nas disciplinas escolares de Cosmografia e de Geografia permanecem nos atuais livros didáticos. O uso do termo "Cosmografia" foi resgatado nesta pesquisa e o estudo de sua ressignificação proporcionou o surgimento do termo Cosmografia Geográfica. A Cosmografia Geográfica é um campo de estudos da Geografia, cujo conjunto de conhecimentos e habilidades é predominantemente escolar. Estuda a interface entre os conhecimentos terrestres e os celestes e lhes atribui significância geográfica. Analisa as relações humanas e naturais com o Espaço Sideral e suas consequências para a sociedade e a natureza.

    Aunque el concepto de "Cosmografía" no se usa desde la década de los '80 del siglo pasado, los temas astronómicos que se enseñaban anteriormente en las asignaturas escolares de Cosmografía y de Geografía permanecen en los actuales libros didácticos.

    2008-12-01

    Volunteer advisors at Itaocara Astronomy Club Marcos Pontes(CAIMP), in their majority high school students, introduced students at Teotônio Brandão Vilela Elementary School to basic concepts in Astronomy, Physics, and Mythology. Computer Science, Arts, puppetry, and educational videos were used to stimulate students to share their feelings and test their knowledge of the concepts presented. The work done by the volunteers helped boost the student's self-esteem and improved their oral skills by applying their knowledge of Physics and Astronomy in Lab experiments. The main goals of the CAIMP are the possibility of including astronomy in Elementary school curricula and developing an interdisciplinary work involving Astronomy, Arts, and Mythology. Through tests and reports, the students who participated in the Brazilian Astronomy Olympics, showed an increase in their knowldge of the sujects presented during the volunteer work. Durante el curso de un trabajo voluntario con estudiantes de nivel primario (1 º a 4 º grado), los guías de Astronomía miembros del CAIMP (Club de Astronomía de Itaocara "Marcos Puentes"), en su mayoría estudiantes secundarios, desarrollaron un trabajo de introducción a las Ciencias y Astronomía con alumnos del colegio estatal Teotônio Vilela Brandão. A través de talleres de informática, artes, videos educativos y teatro de títeres, los estudiantes pudieron expresar sus conocimientos y emociones frente a las leyendas mitológicas con las que se inició el trabajo de introducción. La labor desarrollada por los guías con los alumnos promovió la integración entre las aulas del colegio haciéndolos participar en actividades con el fin de estimular su expresión verbal y aumentar su autoestima. Trabajando diversas formas de expresión, los alumnos pudieron realizar experimentos y conocer algunos conceptos de Física y Astronomía al mismo tiempo que adquirían autonomía para la libre expresión de sus sentimientos y de los conocimientos recibidos. El trabajo en sí ha mostrado además de la posibilidad de la inclusión de la Astronomía en la Educación Primaria, la posibilidad de un trabajo interdisciplinario en los niveles iniciales incluyendo Astronomía, Arte y Mitología. Los resultados presentados por los estudiantes en las Olimpiadas promovidas en la escuela y por la OBA (Olimpiada Brasilera de Astronomía) permitieron verificar un creciente aprendizaje y estimulo hacia las materias científicas, comprobados por la apropiada expresión de los conceptos adquiridos de astronomía y presentados en evaluaciones o en informes obtenidos de ellos mismos, sus familias y profesores. Desenvolvendo um trabalho voluntário junto aos alunos do ensino fundamental no 1º ciclo (1ª a 4ª série), os monitores de Astronomia membros do CAIMP (Clube de Astronomia de Itaocara Marcos Pontes), que eram em sua maioria alunos do ensino médio, desenvolveram um trabalho de aproximação entre os alunos do Colégio Estadual Teotônio Brandão Vilela e os temas envolvendo Ciências e Astronomia. Através de oficinas de informática, artes, vídeos educativos e teatros de fantoches, os alunos puderam expressar seus conhecimentos e emoções diante das lendas mitológicas com as quais começaram a ter contato. O trabalho desenvolvido pelos monitores junto aos alunos proporcionou a integração entre as turmas do colégio e os levou a participação em atividades de maneira a estimular sua oralidade e aumentar sua auto-estima. Trabalhando várias formas de expressões, os alunos puderam realizar seus experimentos e conhecer alguns conceitos de Física e Astronomia, enquanto adquiriam autonomia para se expressarem de acordo com seus sentimentos e conhecimentos adquiridos. O trabalho em si mostrou além da possibilidade de inserção de Astronomia no Ensino Fundamental, a possibilidade de realização de um trabalho interdisciplinar nas séries iniciais envolvendo Astronomia, Arte e Mitologia. Os resultados apresentados pelos alunos nas Olimpíadas promovidas na escola e pela OBA (Olimpíada Brasileira de Astronomia) possibilitaram a verificação de uma crescente aprendizagem e estímulo ao conhecimento de temas científicos, que foi comprovado diante da apropriação dos conceitos de Astronomia adquiridos e apresentados em resultados como avaliações, ou ainda, diante dos relatos obtidos dos mesmos, suas famílias e professores.

    INTRODUCTION: Maximal oxygen uptake (VO2 max) is associated with cardiovascular and metabolic risks but it is difficult to assess in obese children. The objective of this study was to develop an equation to estimate VO2 (mL/kg/min) and to check the % of tests that were maximal according to recommended criteria. METHODS: Stress tests were analyzed of 222 subjects (94 male and 128 female with a BMI above the 85 percentile for age and sex), and repeated 4 months later. Mean age was 9.4 ± 1.1 years and weighed 52.4 ± 13.3 kg. Body fat % (40.5 + 6.2) was determined by DXA (Hologic QDR 4500W). The protocol on the treadmill started with a warm up at 2.5 and 3 mph with a slope of 0% and 2%. The speed was kept at 3 mph for all the stages and the slope was increased 2% every 2 minutes. Statistical analysis (descriptive, t-test and ANOVAS 2×2×2) was done with SPSS 15.0. RESULTS: Only 35% of the tests were maximal. The equation calculates was Y = 2.6x + 22.3 (x = protocol stage). Data pre and post treatment were not statistically different DISCUSSION: Increments in VO2 were consistent despite subject diversity (sex, % body fat, physical fitness, treatment). CONCLUSION: To be able to estimate VO2 at the different stages of the test without complex equipment or specialized staff, will facilitate the performance of stress tests on a daily basis.

  19. Recharge areas and hydrochemistry of carbonate springs issuing from Semmering Massif, Austria, based on long-term oxygen-18 and hydrochemical data evidence

    NASA Astrophysics Data System (ADS)

    Yehdegho, Beyene; Reichl, Peter

    2002-10-01

    Résumé. Les teneurs en oxygène-18 et l'hydrochimie des sources émergeant du massif de Semmering ont été suivies de manière intensive dans le but de caractériser les zones de recharge et l'évolution hydrochimique. L'effet d'altitude sur le δ18O a été déterminé grâce aux données isotopiques et hydrogéologiques de petites sources de référence, principalement en terrains cristallins; cet effet est d'environ -0,27 et -0,21‰ par 100 m pour les versants respectivement nord et sud du massif. En appliquant ces valeurs, l'altitude moyenne de recharge des sources a été calculée. Pour les sources à fort débit issues des carbonates, elle est comprise entre 1,100 et 1,400 m, compatible avec le cadre topographique et hydrogéologique des calcaires et des dolomies de l'Austro-alpin inférieur alimentant ces sources. La composition chimique des sources des carbonates est dominée par les ions Ca2+, Mg2+, HCO3- et SO42-. Les sources sont presque toutes proches de la saturation par rapport à la calcite, mais sont sous-saturées en dolomite (sauf quelques sources proches de la saturation). Comme cela est habituel en ce qui concerne le dioxyde de carbone fourni par les sols en régions montagneuses, la pCO2 équilibrante moyenne est faible, comprise entre 10-3.0 et 10-2.5 atm (0,1 à 0,3% en volume). En ce qui concerne les variations à long terme, le pH, SIc, Sid et la pCO2 équilibrante sont soumis à des variations saisonnières, alors que les concentrations en Ca2+, Mg2+ et HCO3- ne varient pratiquement pas. En intégrant les résultats de δ18O et les données hydrochimiques, la variabilité altitudinale du chimisme des eaux souterraines des carbonates est démontrée. Reflétant les variations d'activité biologique et des conditions de recharge dans les zones d'alimentation, une covariation négative résulte de l'altitude de recharge et de la pCO2 et la concentration en HCO3- n'est pas modifiée par aucun des termes source ou puits, ce qui fait varier la chimie des carbonates. La pCO2 et la concentration en HCO3- diminuent respectivement d'environ 0,22 unité log (atm) et 38,6 mg/l pour un accroissement de 100 m de l'altitude de recharge. Resumen. Se ha muestreado exhaustivamente el contenido en oxígeno-18 y la hidroquímica de los manantiales existentes en el macizo de Semmering (Austria) con el fin de caracterizar las áreas de recarga y su evolución hidroquímica. Se ha determinado el efecto altitudinal del δ18O con datos isotópicos e hidrogeológicos obtenidos en pequeños manantiales originados en rocas cristalinas que sirven como nivel de referencia; los resultados han sido de -0,27‰ por cada 100 m en la zona Morte del macizo, y de -0,21‰/100 m hacia el Sur. Aplicando estos valores, se ha calculado la altitud promedio a la que se produce su recarga. Para los manantiales de caudal elevado en materiales carbonatados, la altitud de recarga varía entre 1.100 y 1.410 m, cosa que es compatible con el marco topográfico e hidrogeológico de las rocas calizas y dolomíticas Mesozoicas propias del Austroalpino Bajo que los alimenta. La composición hidroquímica de los manantiales carbonatados está dominada por los iones calcio, magnesio, bicarbonato y sulfato. Los manantiales están casi saturados en calcita, pero subsaturados en dolomita, excepto en algunos que parecen hallarse cerca de la saturación. Como caracteriza a los suelos en regiones montañosas, la presión parcial de equilibrio del dióxido de carbono (PCO2) es baja, con valores comprendidos entre 10-3,0 y 10-2,5 atm. A largo plazo, el pH y los valores calculados de los índices de saturación en calcita (SIc) y en dolomita (SId), junto con la PCO2 en equilibrio, evidencian una fuerte estacionalidad; en cambio, las concentraciones de calcio, magnesio y bicarbonato prácticamente no varían. Integrando los resultados de δ18O y de la hidroquímica, se demuestra la variabilidad de la química de aguas subterráneas carbonatadas con respecto a la altitud. Reflejando el cambio sistemático de la actividad biótica y de las condiciones de recarga en la cuenca, se obtiene una correlación negativa entre la altitud de la recarga y la PCO2, mientras que la concentración de bicarbonato no es modificada por términos fuente/sumidero, lo cual atribuye el cambio a la química de los carbonatos. La PCO2 y el bicarbonato disminuyen aproximadamente 0,22 unidades logarítimicas (en atmósferas) y 38,6 mg/l, respectivamente, por cada 100 m de incremento en la altitud de recarga.

  1. Battlefield awareness computers: the engine of battlefield digitization

    1997-06-01

    To modernize the army for the 21st century, the U.S. Army Digitization Office (ADO) initiated in 1995 the Force XXI Battle Command Brigade-and-Below (FBCB2) Applique program which became a centerpiece in the U.S. Army's master plan to win future information wars. The Applique team led by TRW fielded a 'tactical Internet' for Brigade and below command to demonstrate the advantages of 'shared situation awareness' and battlefield digitization in advanced war-fighting experiments (AWE) to be conducted in March 1997 at the Army's National Training Center in California. Computing Devices is designated the primary hardware developer for the militarized version of the battlefield awareness computers. The first generation of militarized battlefield awareness computer, designated as the V3 computer, was an integration of off-the-shelf components developed to meet the agressive delivery requirements of the Task Force XXI AWE. The design efficiency and cost effectiveness of the computer hardware were secondary in importance to delivery deadlines imposed by the March 1997 AWE. However, declining defense budgets will impose cost constraints on the Force XXI production hardware that can only be met by rigorous value engineering to further improve design optimization for battlefield awareness without compromising the level of reliability the military has come to expect in modern military hardened vetronics. To answer the Army's needs for a more cost effective computing solution, Computing Devices developed a second generation 'combat ready' battlefield awareness computer, designated the V3+, which is designed specifically to meet the upcoming demands of Force XXI (FBCB2) and beyond. The primary design objective is to achieve a technologically superior design, value engineered to strike an optimal balance between reliability, life cycle cost, and procurement cost. Recognizing that the diverse digitization demands of Force XXI cannot be adequately met by any one computer hardware solution, Computing Devices is planning to develop a notebook sized military computer designed for space limited vehicle-mounted applications, as well as a high-performance portable workstation equipped with a 19', full color, ultra-high resolution and high brightness active matrix liquid crystal display (AMLCD) targeting the command posts and tactical operations centers (TOC) applications. Together with the wearable computers Computing Devices developed at the Minneapolis facility for dismounted soldiers, Computing Devices will have a complete suite of interoperable battlefield awareness computers spanning the entire spectrum of battle digitization operating environments. Although this paper's primary focus is on a second generation 'combat ready' battlefield awareness computer or the V3+, this paper also briefly discusses the extension of the V3+ architecture to address the needs of the embedded and command post applications.3080

  2. Geochemical and stable isotopic evolution of the Guarani Aquifer System in the state of São Paulo, Brazil

    NASA Astrophysics Data System (ADS)

    Sracek, Ondra; Hirata, Ricardo

    2002-09-01

    The purpose of this report is to explain geochemical and stable isotopes trends in the Brazilian unit of the Guarani Aquifer System (Botucatu and Piramboia aquifers) in São Paulo State, Brazil. Trends of dissolved species concentrations and geochemical modeling indicated a significant role of cation exchange and dissolution of carbonates in downgradient evolution of groundwater chemistry. Loss of calcium by the exchange for sodium drives dissolution of carbonates and results in Na-HCO3 type of groundwater. The cation-exchange front moves downgradient at probably much slower rate compared to the velocity of groundwater flow and at present is located near to the cities of Sertãozinho and Águas de Santa Barbara (wells PZ-34 and PZ-148, respectively) in a shallow confined area, 50-70 km from the recharge zone. Part of the sodium probably enters the Guarani Aquifer System. together with chloride and sulfate from the underlying Piramboia Formation by diffusion related to the dissolution of evaporates like halite and gypsum. High concentrations of fluorine (up to 13.3 mg/L) can be explained by dissolution of mineral fluoride also driven by cation exchange. However, it is unclear if the dissolution takes place directly in the Guarani Aquifer System or in the overlying basaltic Serra Geral Formation. There is depletion in δ2H and δ18O values in groundwater downgradient. Values of δ13C(DIC) are enriched downgradient, indicating dissolution of calcite under closed system conditions. Values of δ13C(DIC) in deep geothermal wells are very high (>-6.0‰) and probably indicate isotopic exchange with carbonates with δ13C about -3.0‰. Future work should be based on evaluation of vertical fluxes and potential for penetration of contamination to the Guarani Aquifer System. Résumé. Cet article a pour objet d'expliquer l'évolution de la géochimie et des isotopes stables dans l'unité brésilienne du système aquifère du Guarani (aquifères de Botucatu et Piramboia), dans l'État de Sao Paulo (Brésil). L'évolution des concentrations des espèces dissoutes et la modélisation géochimique ont fait apparaître le rôle notable des échanges de cations et de la dissolution des carbonates de l'amont vers l'aval des nappes. La perte de calcium par échange de cation avec le sodium pilote la dissolution des carbonates et donne naissance à des eaux souterraines à faciès Na-HCO3. Le front d'échange de cation se déplace vers l'aval probablement plus lentement que la vitesse d'écoulement de l'eau souterraine et est actuellement situé à proximité des villes de Sertaozinho et de Aguas de Santa Barbara (respectivement puits PZ-34 et PZ-148), dans une zone captive proche de la surface, à 50-70 km de la zone de recharge. Une partie du sodium provient probablement du système aquifère du Guarani, associée aux chlorures et aux sulfates de la formation Piramboia sous-jacente, par diffusion liée à la dissolution d'évaporites comme la halite et le gypse. De fortes concentrations en fluorures (jusqu'à 13,3 mg/L) peuvent être expliquées par la dissolution d'un minéral fluoré également pilotée par l'échange de cations. Cependant, on ne sait pas bien si la dissolution intervient directement dans le système aquifère du Guarani ou dans la formation basaltique sus-jacente de Serra Geral. Les valeurs de δ2H et δ18O décroissent vers l'aval de la nappe. Les valeurs de δ13C du carbone minéral dissous sont enrichies vers l'aval, indiquant qu'il se produit une dissolution de calcite en système fermé. Les valeurs de δ13C du carbone minéral dissous dans les puits géothermaux profonds sont très élevées (supérieures à -6,0‰) et rendent probablement compte d'échanges isotopiques avec des carbonates possédant un δ13C d'environ -3,0‰. De prochaines études devront s'attacher à évaluer les flux verticaux et le potentiel de pénétration de contamination du système aquifère du Guarani. Resumen. El propósito de este informe es explicar las tendencias geoquímicas y de los isótopos estables en la unidad brasileña del Sistema Acuífero Guaraní (acuíferos de Botucatu y Piramboya), en el Estado de Sao Paulo. Las concentraciones de especies disueltas y los resultados de modelaciones geoquímicas indican que el intercambio catiónico y la disolución de carbonatos desempeñan un papel importante en la evolución aguas abajo del acuífero. La disminución de calcio por el intercambio con sodio origina la disolución de carbonatos, dando lugar a aguas subterráneas de tipo bicarbonatado sódico. El frente de intercambio catiónico se desplaza a una velocidad probablemente mucho más lenta que la del flujo de agua; actualmente, se halla cerca de las ciudades de Sertaozinho y Aguas de Santa Bárbara (pozos PZ-34 y PZ-148, respectivamente), en una zona confinada somera que dista entre 50 y 70 km del área de recarga. Parte del sodio entra probablemente en el Sistema Acuífero Guaraní junto con el cloruro y el sulfato procedentes de la Formación Piramboia inferior, debido a la difusión relacionada con la disolución de evaporitas como la halita y los yesos. Se puede explicar las elevadas concentraciones de flúor (hasta 13,3 mg/L) por la disolución de fluoruro mineral, que sucede también por intercambio catiónico. Sin embargo, no está claro si la disolución ocurre directamente en el Sistema Acuífero Guaraní o en la Formación basáltica superior de Serra Geral. Hay una reducción de δ2H y de δ18O a favor del gradiente hidráulico. Hay un enriquecimiento en δ13C inorgánico aguas abajo, lo que indica que la calcita se disuelve en condiciones de sistema cerrado. Los valores de δ13C inorgánico en pozos geotérmicos profundos son muy altos (mayores que -6,0‰), y probablemente apuntan a un intercambio isotópico con carbonatos de δ13C que tiene un valor del orden del -3,0‰. Las líneas de investigación deberían centrarse en evaluar los flujos verticales y el potencial de penetración de contaminantes en el Sistema Acuífero Guaraní.

    The cave of Toca do Serrote do Artur (São Raimundo Nonato Archaeological Area, southeastern Piauí, Brazil) has yielded a Mammalian community constituted of Dasypus septemcinctus, Propraopus cf. sulcatus, Hoplophorus euphractus, Glyptodon clavipes, Conepatus sp., Panthera onca, Equus neogaeus, Dicotyles tajacu, Tayassu pecari, Palaeolama major, Mazama guazoubira, Mazama americana and a large Cervid. In comparison with the Mammalian fauna of the other sites from the same area, such a list shows a comparatively reduced biodiversity together with the presence of rare ( Hoplophorus, Conepatus) or unknown ( Propraopus, Palaeolama major) taxa. Explanation lies in the more recent age of the fossiliferous layers, probably Lower Holocene, as demonstrated by two 14C dating of 8 490 ± 120 BP and 6 890 ± 60 BP of the highest one. Moreover, that fauna shows the late survival of some genera ( Propraopus, Hoplophorus, Glyptodon, Equus, Palaeolama) together with climatic modifications related to the Pleistocene-Holocene transition.

    The paper presents the preliminary results of an integrated multidiscipliary research project concerning the urban area of the modern Durres (ancient Dyrrachium). Here a joint Italian and Albanian researcher are starting preliminary investigations on the place of an ancient roman villa placed in the urban centre of the modern town. In a initial phase are offering interesting results the use of a rich multitemporal remote sensing data-set, historical aerial photos of 1920s and 1930s, photos of USA spy satellites of 1960s and 1970s (Corona KH-4A and KH-4B), and very high resolution satellite imagery. The historical aerial documentation is very rich and includes aerial photogrammetrich flights of two Italian Institutions: the private company SARA - Società Anonima Rilevamenti Aerofotogrammetrici in Rome (1928) and the IGM - Istituto Geografico Militare (1936, 1937 e 1941), which flew on Durres for purposes of cartographic production and military. These photos offer an image of the city before the urban expansion after the Second World War and in recent decades, progressively documented by satellite images of the 1960s-1970s and recent years. They enable a reconstruction of the ancient topography of the urban area, even with the possibility of detailed analysis, as in the case of the the Roman villa, nowadays buried under a modern garden, but also investigated with a GPR survey, in order to rebuild its plan and contextualize the villa in relation to the urban area of the ancient Dyrrachium.

  7. Breaking the cyber-security dilemma: aligning security needs and removing vulnerabilities.

    2014-09-01

    Current approaches to cyber-security are not working. Rather than producing more security, we seem to be facing less and less. The reason for this is a multi-dimensional and multi-faceted security dilemma that extends beyond the state and its interaction with other states. It will be shown how the focus on the state and "its" security crowds out consideration for the security of the individual citizen, with detrimental effects on the security of the whole system. The threat arising from cyberspace to (national) security is presented as possible disruption to a specific way of life, one building on information technologies and critical functions of infrastructures, with relatively little consideration for humans directly. This non-focus on people makes it easier for state actors to militarize cyber-security and (re-)assert their power in cyberspace, thereby overriding the different security needs of human beings in that space. Paradoxically, the use of cyberspace as a tool for national security, both in the dimension of war fighting and the dimension of mass-surveillance, has detrimental effects on the level of cyber-security globally. A solution out of this dilemma is a cyber-security policy that is decidedly anti-vulnerability and at the same time based on strong considerations for privacy and data protection. Such a security would have to be informed by an ethics of the infosphere that is based on the dignity of information related to human beings. PMID:24781874

    COTS+ was defined in this study as commercial off-the-shelf (COTS) products, ruggedized and militarized components, and COTS technology. This study cites the benefits of integrating COTS+ in space, postulates a COTS+ integration methodology, and develops requirements and an architecture to achieve integration. Developmental needs and concerns were identified throughout the study; these needs, concerns, and recommendations relative to their abatement are subsequently presented for further action and study. The COTS+ concept appears workable in part or in totality. No COTS+ technology gaps were identified; however, radiation tolerance was cited as a concern, and the deferred maintenance issue resurfaced. Further study is recommended to explore COTS+ cost-effectiveness, maintenance philosophy, needs, concerns, and utility metrics. The generation of a development plan to further investigate and integrate COTS+ technology is recommended. A COTS+ transitional integration program is recommended. Sponsoring and establishing technology maturation programs and COTS+ engineering and standards committees are deemed necessary and are recommended for furthering COTS+ integration in space.

    Vehicle intrusion is considered a significant threat for critical zones specially the militarized zones and therefore vehicles monitoring has a great importance. In this paper a small wireless sensor network for vehicle intrusion monitoring consists of a five inexpensive sensor nodes distributed over a small area and connected with a gateway using star topology has been designed and implemented. The system is able to detect a passage of an intrusive vehicle, classify it either wheeled or tracked, and track the direction of its movement. The approach is based on Vehicle's ground vibrations for detection, vehicle's acoustic signature for classification and the Energy- based target localization for tracking. Detection and classification are implemented by using different algorithms and techniques including Analog to Digital Conversion, Fast Fourier Transformation (FFT) and Neural Network .All of these algorithms and techniques are implemented locally in the sensor node using Microchip dsPIC digital signal controller. Results are sent from the sensor node to the gateway using ZigBee technology and then from the gateway to a web server using GPRS technology.

    Each individual may be identified by characterizing its genetic material by DNA fingerprinting technology. Its application in Mexico demands a knowledge of the allelic and genotypic diversity of the DNA markers and the probability that two individuals may have the same fingerprint. In the present study the allelic and genotypic diversities of the loci D12S11 (MS43A), D7S22 (g3) and D1S7 (MS1) were determined in 100 Mexican students of the military school of medicine (Escuela Médico Militar de México). The mean allelic frequency of the loci MS43A, g3, and MS1 was 0.01, 0.008 and 0.006, respectively. The heterozygosity of MS43A and g3 was 98 and 99% for MS1. The probability that two individuals might have the same genetic pattern was 2.0 x 10(-4), 1.3 x 10(-4) and 7.2 x 10(-5) for the loci MS43A, g3 and MS1, respectively, and as low as 1.9 x 10(-12) for the three taken together. These data indicate that the genetic diversity of these DNA fingerprinting markers in the Mexican population is high enough to warrant its use in paternity testing and in the identification of individuals in forensic medicine.

    Global climate change is one of the most severe problems facing societies around the world. Very few assessments of the social forces that influence greenhouse gas emissions have examined gender inequality. Empirical research suggests that women are more likely than men to support environmental protection. Various strands of feminist theory suggest that this is due to women's traditional roles as caregivers, subsistence food producers, water and fuelwood collectors, and reproducers of human life. Other theorists argue that women's status and environmental protection are linked because the exploitation of women and the exploitation of nature are interconnected processes. For these theoretical and empirical reasons, we hypothesize that in societies with greater gender equality there will be relatively lower impacts on the environment, controlling for other factors. We test this hypothesis using quantitative analysis of cross-national data, focusing on the connection between women's political status and CO(2) emissions per capita. We find that CO(2) emissions per capita are lower in nations where women have higher political status, controlling for GDP per capita, urbanization, industrialization, militarization, world-system position, foreign direct investment, the age dependency ratio, and level of democracy. This finding suggests that efforts to improve gender equality around the world may work synergistically with efforts to curtail global climate change and environmental degradation more generally.

    The first hospital services in America were created in the Dominican Republic--formerly known as the Espariola--by a black woman at the beginning of the Conquest. In 1503 fray Nicolá de Ovando, second governor of the Española built what nowadays would be considered a hospital and named it Hospital San Nicolás de Bari (Saint Nicholas Hospital). During the Colony, the poor and sick were cared for following the precepts of the Catholic religion in the San Nicolas de Bari Hospital. In 1586 the hospital was badly damaged due to a pirate's attack. During the XVIII century the hospital cared for ill soldiers and so its name was changed to Hospital Militar (Military Hospital). Between 1795 and 1865 the social and political conditions under which the hospital had to operate made running the hospital a tremendously hard task. Today, the physical ruins of the Hospital San Nicolás de Bari--built in typical Spanish colonial style--with thick fortress like walls and stone floors echoes a place where rustic beds were used to care for patients. The San Nicolás de Bari Hospital operated for over 350 years. It finally disappeared during the second part of the XIX century after undergoing severe financial restrictions and lack of supplies and personnel that in the end hampered its work. PMID:16548297

  13. An Ottoman response to Darwinism: İsmail Fennî on Islam and evolution.

    The Scopes trial (1925) fuelled discussion in the United States on the social and political implications of Darwinism. For the defenders of the 1925 Tennessee law - which prohibited the teaching of Darwinism in schools - Darwinism was, amongst other things, responsible for the German militarism which eventually led to the First World War. This view was supported by İsmail Fennî, a late Ottoman intellectual, who authored a book immediately after the trial which aimed to debunk scientific materialism. In it, he claimed that Darwinism blurred the distinction between man and beast and thus destroyed the foundations of morality. However, despite his anti-Darwinist stance, İsmail Fennî argued against laws forbidding the teaching of Darwinism in schools, and emphasized that even false theories contributed to scientific improvement. Indeed, because of his belief in science he claimed that Muslims should not reject Darwinism if it were supported by future scientific evidence. If this turned out to be the case, then religious interpretations should be revised accordingly. This article contributes to the literature on early Muslim reactions to Darwinism by examining the views of İsmail Fennî, which were notably sophisticated when compared with those of the anti-religious Darwinist and anti-Darwinist religious camps that dominated late Ottoman intellectual life.

  14. On the Frontier of Knowledge: A Discussion of Alien Civilizations

    Thomson, Shelley

    Possible States Theory discusses change in the abstract; it has a single description of change, equally applicable to acts of mind and physical phenomena. Change is defined as an interaction between collections of possible states, which include past, future and possible outcomes. All possible outcomes coincide in the complex present. This allows a competent observer to participate in possible states interactions that are unconstrained by time, distance or conservation laws. The technique of coordinate remote viewing was used in a study of technologically advanced alien life forms. The primary focus of the study was on two specific species but general knowledge of multiple others was also obtained. One of the two major species may be characterized as well disposed while the other may be classed as exploitative. Both species maintain facilities on Earth. The differences between the human species and these species are profound and go well beyond levels of technological development. Both alien species are forms of collective intelligence, which was true of all intelligent species studied. The human decision to militarize interaction with alien species may be characterized as inappropriate and potentially counterproductive. Unsuccessful efforts to communicate were made by all sides prior to this study. Substantial obstacles to communication exist based upon attitudes and beliefs of both humans and aliens. Among the most important findings are the unusual, perhaps unique biodiversity found on the Earth and the value aliens place on sentience. To the extent that the conclusions are correct, these findings hold significant implications for the future of humanity.

    Egypt, whose soil germinated the first civilization, monotheism, refined ethics and culture of sharing the abundance of extracted natural resources among its populace became the crucible proliferating de-novo genotypes of organic and moral maladies. The enigma is these mutations are synchronized by several factors, namely; failing medical health, if there is any, abundant filth, cultural bankruptcy, over population, dogmatic militarism, societal deprivation and characterization, etc. These domineering ingredients fossilized Egypt as of 1952 coup in an irrevocable national apoptosis, together with the crippled social justice and imbalanced distribution of wealth among Egyptians, rates of bacterial and viral evolution to second generation resistant to known medical interventions are expected to exponentially accelerate. Therefore, it deemed essential to elaborate on pollution and psychosis-induced inflammations and grievous crimes evoked by dogmatic cults at the breeding source, e.g., ghettos and sporadic locations of the homeless in Cairo, Alexandria and Upper Egyptian villages. While this second generation of viral and bacterial diseases could labor plagues threatening the precariously maintained so-called social fabric of Middle Eastern countries, that are uniquely segregating its populace according to their dogmatic affiliations and soaked into intolerance, it would definitely compromise the integrity of the expensively managed medical care system of developed countries.

  16. Health, stabilization and securitization: towards understanding the drivers of the military role in health interventions.

    2011-01-01

    In the post-Cold War world, health issues have become firmly rooted in state foreign policies through initiatives such as the UK's 'Health is Global' strategy. However, since 9/11, there has also been growing interest in the interactions between health sector interventions and state fragility. Whilst fragility clearly has a negative impact upon both health outcomes and the capacity of the state to respond to health issues generally, there has been a growing assumption amongst policy makers and practitioners alike that carefully formulated health programmes contribute both to social stability and more widely to a state- and peace-building agenda. This process risks being co-opted by the debates on 'stabilization'--a discourse configured around addressing state fragility and often associated with the interventions in Iraq and Afghanistan. Consequently, this article explores the emergence of health interventions as 'strategic tools' linked to the stabilization debate, explores the emergence of the 'health as a bridge for peace' (HBP) debate, assesses some of the evidence available for HBP and finally focuses on the issues arising from the use of militarized health interventions, particularly in Helmand.

  17. The dispersion of pederasty and the athletic revolution in sixth-century BC Greece.

    2005-01-01

    Dorian Crete and Thebes are conventionally seen by ancient sources as the originators of pederasty; modern historians see support for this view in Dorian male-centered militarism and sexual segregation in upbringing. Here athletic culture, including training, nudism, and competition, is argued to be a chief 'trigger' for the emergence of pederasty in Sparta and its relatively rapid spread to other Greek states in the seventh to sixth centuries BC. Athletic nudity, in particular, was not a device to enforce civic egalitarianism, as some have argued, but is a persistently erotic incentive that reinforces hegemonic maleness and advertises the individual's virtuous exercise of restraint. In particular, Sparta is found to be the likely source of generalized athletic nudity combined with open pederasty in the early seventh century BC. Nudism in Greek art is erotically charged and not, as others argue, simply a gender marker in the seventh century. Generalized athletic nudity spread to other Greek states emulating the successful Spartan model by the 'athletic revolution' of the early sixth century. With athletic nudity, open pederasty, again following Sparta, was fostered. PMID:16338890

    What is the role of education in wartime? To what extent should environmental and science educators directly address violent conflict and a culture of prolonged war? This article gestures with empathy toward all educators who are working in wartime. It posits that a critical pedagogy of place provides a theoretical framework that contextualizes all environmental work and all education in the context of cultural politics. I argue that a fundamental component of a critical, place-based inquiry must be acknowledging the contested history of colonization with respect to land (environment) and homeland (culture). I cannot think of a place on the planet where this history is as complex and contested than it is in Israel and Palestine. However, colonization and its legacy is a shared reality around the world, and acknowledging the context of colonization should not be limited to inquiry in places where the bombs are still smoldering and where the rubble has yet to be cleared. Acknowledging colonization may be especially appropriate in the US, where the historical record of militarized colonization remains hidden behind the myths of global "progress" for the world's remaining "superpower."

    In this paper, we investigate the intersections of gender, health and human rights in sites of political exclusion. We apply the political theory of Giorgio Agamben on 'states of exception', seeking to better understand how the recent 'war on terror', that seemingly knows no limits of time or space, is driving health outcomes in refugee and Internally Displaced Persons (IDP) camps. Reproductive health, militarization, and gender-based violence in camps are explored in depth. The evidence presented reveals a number of contradictions of refugee and IDP camps, further highlighting the need for a more rights based humanitarianism. We conclude that foregrounding states of exception, as a way of understanding current gender dynamics in the social determinants of health, is both epidemiologically necessary and conceptually useful. We find that, in these sites of exclusion, the indispensability of a human rights approach to gender and health equity issues is revealed most directly. Furthermore, we are able to make new connections between the 'crisis of humanitarianism', gender, and health. PMID:19288341

    A significant fraction of world population is projected to experience increased water stress in response to the combined effects of population growth and climate change. Some previous studies have suggested that high water stress had significant causality for civil war, and militarized conflict and trans-boundary water conflict in international river basin. On the other hand, some previous empirical analyses have found that institutionalization (e.g., specific provisions in trans-boundary freshwater treaties) in international river basin was associated with a lower risk of water conflicts during water scarcity. The purpose of this study is to identify these water conflict "hotspots", integrating institutional and governance mechanisms of adaptations to impact of water stress. These adaptations is classified to 4 abilities and skills and then used to calculate the adaptive capacity. The adaptive capacity includes the way to manage water conflict effectively, plan to deal with uncertainty in the future, alter current situation and create institutionalization with common perspective throughout the whole activities. This study identifies water conflict "hotspots" by combining high water stress areas projected by a global water resource model and a lower degree of the adaptive capacity. This study finds that 9 water conflict "hotspots" in Africa, Asia and South America.

  1. Environmental review: A gateway to international cooperation

    The United States and 25 other nations are voting members within a unique international agreement for the governance of Antarctica, a continent larger than the combined area of the United States and Mexico. Antarctica is not a global commons. Rather, nations have agreed to set aside territorial claims for the continent`s natural resources while each pursues legitimate scientific study and carefully controlled commercial tourist-related activities. Through a set of agreements under the Antarctic Treaty System, each nation agrees to a systematic avoidance of environmental damage, exploitation, or militarization of Antarctica. Effective environmental review of planned actions is critical in winning continued international cooperation, efficient management of national antarctic research and education programs, and environmentally sound tourist visits to Antarctica. Over the last five years, NSF has prepared over 200 environmental assessments of planned activities in Antarctica. Thus far, the environmental reviews have proven very useful in the identification of alternative actions and mitigating measures to reduce impacts. In addition to protecting the unique and pristine qualities of Antarctica`s natural resources, environmental reviews are a key component in planning support activities such as field camp installation and removal, construction and decommissioning of facilities at year-round stations, and international cooperative research.

  2. Collapse, environment, and society

    PubMed Central

    2012-01-01

    Historical collapse of ancient states poses intriguing social-ecological questions, as well as potential applications to global change and contemporary strategies for sustainability. Five Old World case studies are developed to identify interactive inputs, triggers, and feedbacks in devolution. Collapse is multicausal and rarely abrupt. Political simplification undermines traditional structures of authority to favor militarization, whereas disintegration is preconditioned or triggered by acute stress (insecurity, environmental or economic crises, famine), with breakdown accompanied or followed by demographic decline. Undue attention to stressors risks underestimating the intricate interplay of environmental, political, and sociocultural resilience in limiting the damages of collapse or in facilitating reconstruction. The conceptual model emphasizes resilience, as well as the historical roles of leaders, elites, and ideology. However, a historical model cannot simply be applied to contemporary problems of sustainability without adjustment for cumulative information and increasing possibilities for popular participation. Between the 14th and 18th centuries, Western Europe responded to environmental crises by innovation and intensification; such modernization was decentralized, protracted, flexible, and broadly based. Much of the current alarmist literature that claims to draw from historical experience is poorly focused, simplistic, and unhelpful. It fails to appreciate that resilience and readaptation depend on identified options, improved understanding, cultural solidarity, enlightened leadership, and opportunities for participation and fresh ideas.

  3. Revisiting the left-wing response to sociobiology: the case of Finland in a European context.

    2015-01-01

    This article revisits the left-wing response to sociobiology in the 1970s and 1980s by examining the sociobiology debate in Finland in a larger European context. It argues that the Finnish academic left's response to sociobiology represents a "third way" alongside the purely negative, often Marxist denial of biology's relevance, which characterized the left's response to sociobiology in many European countries such as Hungary and Sweden, and alongside the disregard that sociobiology confronted in most parts of Eastern Europe, as well as in Germany. In the context of the last great political conflict of the Cold War in Europe, the controversy over the American "Euromissiles" (Pershing II and Tomahawk) in 1979-1983, the Finnish academic left challenged the allegedly fatalistic sociobiological aggression and war theories with an alternative biological language, turning the increasing enthusiasm over evolutionary ideas into a pacifist cause. Using leftist and pacifist forums to inform citizens and politicians of such biologically evolved human characteristics as mutual care and sociability, the Finnish critics of sociobiology wished to boost the public spirit, and to rationalize the pacifist ideal of the European-wide popular movement against nuclear weapons and militarism. As a result, the academic leftists in Finland revived the early twentieth-century tradition of "peace biology." A proper understanding of this development calls for an analysis that acknowledges Finland's special geopolitical and cultural position in the Cold War world between East and West. PMID:24990454

    The development and impact is described of new visually coupled system (VCS) equipment designed to support engineering and human factors research in the military aircraft cockpit environment. VCS represents an advanced man-machine interface (MMI). Its potential to improve aircrew situational awareness seems enormous, but its superiority over the conventional cockpit MMI has not been established in a conclusive and rigorous fashion. What has been missing is a 'systems' approach to technology advancement that is comprehensive enough to produce conclusive results concerning the operational viability of the VCS concept and verify any risk factors that might be involved with its general use in the cockpit. The advanced VCS configuration described here, was ruggedized for use in military aircraft environments and was dubbed the Virtual Panoramic Display (VPD). It was designed to answer the VCS portion of the systems problem, and is implemented as a modular system whose performance can be tailored to specific application requirements. The overall system concept and the design of the two most important electronic subsystems that support the helmet mounted parts, a new militarized version of the magnetic helmet mounted sight and correspondingly similar helmet display electronics, are discussed in detail. Significant emphasis is given to illustrating how particular design features in the hardware improve overall system performance and support research activities.

    Tropical glaciers are an important component of the water budget for high-altitude catchments in much of the central Andes. The majority of tropical Andean glaciers are small, but it has been suggested that because of their numbers the volume of water they contain is significant. Unfortunately, the ice volume measurements needed to inform decision makers have been made for only a handful of tropical glaciers. In August 2012, with the assistance of the Instituto Geográfico Militar in Bolivia, ground penetrating radar (GPR) and differential Global Positioning System (dGPS) measurements were collected along transects totaling 3,189 m in length on the Charquini SE cirque glacier. This small cirque glacier which is located in the southern portion of the Cordillera Real in Bolivia had an approximate surface area in 2012 of 02.42 square kilometers. Our initial observations indicate that the GPR survey was able to adequately capture the ice bedrock interface. Ordinary Kriging was used to develop maps of surface and subsurface topography from the dGPS and GPR observations. In 2012, the Charquini SE glacier contained a minimum of 3,900,000 cubic meters of ice. This information, along with other recent volume measurements for tropical and sub-tropical Andean glaciers, was used to update earlier volume-area scaling relationships established for these glaciers. This relationship will then be applied to determine the volume of water currently stored in tropical Andean glaciers based on previous research on glaciers areas using remote sensing.

    Bokermannohyla nanuzae (Bokermann & Sazima 1973) e B. feioi (Napoli & Caramaschi 2004) pertencem ao grupo de espécies de B. circumdata. A localidade-tipo da primeira espécie é a Serra do Cipó, Serra do Espinhaço, e a da segunda é o Parque Estadual do Ibitipoca, Serra da Mantiqueira, ambas no estado de Minas Gerais, Brasil. O padrão de desenhos dorsais, morfologia oral dos girinos e propriedades temporais dos cantos são indicadas como forma de distinguir essas espécies. Porém, diversos espécimes coletados entre as duas localidades-tipo permanecem sem identificação porque apresentam sobreposição nos caracteres e estados propostos para diagnosticar as duas espécies. Com o objetivo de avaliar a variação desses caracteres, foram realizadas análises de morfologia e morfometria de adultos, vocalizações e morfologia de girinos. Espécimes foram divididos em três unidades taxonômicas operacionais: B. nanuzae (Serra do Cipó e localidades ao norte, Serra do Espinhaço), B. cf. nanuzae (Quadrilátero Ferrífero, Serra do Espinhaço ao sul da Serra do Cipó), e B. feioi (Serra do Ibitipoca, Serra da Mantiqueira). Os padrões de desenhos do dorso e membros apresentam variação clinal e as três unidades são muito similares morfometricamente. As propriedades temporais e espectrais do canto apresentam sobreposição entre essas três unidades. Diferenças diagnósticas originalmente propostas para os girinos são variações intrapopulacionais e ocorrem em espécimes de todas as localidades analisadas. Assim, concluímos que essas três unidades são morfologicamente indistinguíveis. Portanto, Bokermannohyla feioi (Napoli & Caramaschi 2004) é designado como um sinônimo júnior de Bokermannohyla nanuzae (Bokermann & Sazima 1973), o que estende a distribuição geográfica desta para a Serra da Mantiqueira.

    The prospects for survival of children in low and middle income countries are linked to their families socio-economic status (SES), of which income is only one component. Developing a comprehensive measure of SES is required. Informed by clinical experience, a 15-item instrument was designed in Guatemala to categorize SES by five levels in each item. Almost 75% of families attending the Unidad Nacional de Oncologa Peditrica were in the lowest three of six categories, providing a framework for stratified financial and nutritional support. The measure of SES offers an opportunity for examining associations with health outcomes throughout Latin America. PMID:24753054

  10. Variations in hydraulic conductivity with scale of measurement during aquifer tests in heterogeneous, porous carbonate rocks

    NASA Astrophysics Data System (ADS)

    Schulze-Makuch, Dirk; Cherkauer, Douglas S.

    Previous studies have shown that hydraulic conductivity of an aquifer seems to increase as the portion of the aquifer tested increases. To date, such studies have all relied on different methods to determine hydraulic conductivity at each scale of interest, which raises the possibility that the observed increase in hydraulic conductivity is due to the measurement method, not to the scale. This study analyzes hydraulic conductivity with respect to scale during individual aquifer tests in porous, heterogeneous carbonate rocks in southeastern Wisconsin, USA. Results from this study indicate that hydraulic conductivity generally increases during an individual test as the volume of aquifer impacted increases, and the rate of this increase is the same as the rate of increase determined by using different measurement methods. Thus, scale dependence of hydraulic conductivity during single tests does not depend on the method of measurement. This conclusion is supported by 22 of 26 aquifer tests conducted in porous-flow-dominated carbonate units within the aquifer. Instead, scale dependency is probably caused by heterogeneities within the aquifer, a conclusion supported by digital simulation. All of the observed types of hydraulic-conductivity variations with scale during individual aquifer tests can be explained by a conceptual model of a simple heterogeneous aquifer composed of high-conductivity zones within a low-conductivity matrix. Résumé Certaines études ont montré que la conductivité hydraulique d'un aquifère semble augmenter en même temps que la partie testée de l'aquifère s'étend. Jusqu'à présent, ces études ont toutes reposé sur des méthodes de détermination de la conductivité hydraulique différentes pour chaque niveau d'échelle, ce qui a conduit à penser que l'augmentation observée de la conductivité hydraulique pouvait être due aux méthodes de mesure et non à l'effet d'échelle. Cette étude analyse la conductivité hydraulique par rapport au niveau d'échelle au cours d'essais de nappe individuels, dans des roches carbonatées poreuses, hétérogènes du sud-est du Wisconsin (Etats-Unis). Les résultats obtenus indiquent que la conductivité hydraulique augmente en général au cours d'un essai individuel en même temps que le volume d'aquifère concerné augmente, et que le taux d'augmentation est le même que celui déterminé en utilisant différentes méthodes de mesures. Ainsi, le fait que la conductivité hydraulique dépende de l'échelle d'observation au cours d'essais uniques ne résulte pas de la méthode de mesure. Cette conclusion est confirmée par 22 essais de nappe sur 26 entrepris dans des unités carbonatées àécoulement poreux dominant dans l'aquifère. En revanche, cette dépendance du niveau d'échelle est probablement due aux hétérogénéités existant dans l'aquifère, conclusion confortée par une simulation. Tous les types de variations de conductivité hydraulique en fonction de l'échelle au cours d'essais de nappe peuvent être expliqués par un modèle conceptuel d'aquifère hétérogène simple constitué par des zones à forte conductivitéà l'intérieur d'une matrice à faible conductivité. Resumen Estudios previos han mostrado que la conductividad hidráulica (K) de un acuífero parece crecer con el volumen ensayado. Hasta ahora, estos estudios se han basado en la utilización de métodos distintos para la determinación de la conductividad hidráulica a cada escala de interés, lo que hace pensar en la posibilidad de que este aumento observado sea debido a la variación en el método de medida y no al cambio de escala. Este estudio analiza el valor de K en función de la escala a partir de ensayos individuales en rocas carbonatadas heterogéneas y porosas al sudeste de Wisconsin, EEUU. Los resultados de este estudio indican que la K obtenida en ensayos individuales crece generalmente al aumentar el volumen de acuífero implicado en el ensayo, y que la tasa de crecimiento es la misma que se determinaría usando diferentes métodos. Por tanto, la dependencia de la conductividad hidráulica con la escala en ensayos aislados no depende del método de medida. Esta conclusión está refrendada por 22 de los 26 ensayos llevados a cabo en las unidades carbonatadas más porosas del acuífero. Por el contrario, la dependencia con la escala está causada probablemente por las heterogeneidades en el propio acuífero, lo que se corrobora con simulaciones digitales. Todos los tipos de variaciones de K con la escala observados para los ensayos individuales se pueden explicar mediante un modelo conceptual simple que supone un acuífero heterogéneo compuesto por zonas de alta conductividad embebidas en una matriz poco conductiva.

  11. Some current methods to represent the heterogeneity of natural media in hydrogeology

    NASA Astrophysics Data System (ADS)

    de Marsily, G.; Delay, F.; Teles, V.; Schafmeister, M. T.

    We have known for a long time that the material properties of the subsurface are highly variable in space. We have learned that this variability is due to the extreme complexity and variation with time of processes responsible for the formation of the earth's crust, from plate tectonics to erosion, sediment transport, and deposition, as well as to mechanical, climatic, and diagenetic effects. As geologists, we learned how to "read" this complex history in the rocks and how to try to extrapolate in space what we have understood. As physicists, we then learned that to study flow processes in such media we must apply the laws of continuum mechanics. As mathematicians using analytical methods, we learned that we must simplify by dividing this complex continuum into a small number of units, such as aquifers and aquitards, and describe their properties by (constant) equivalent values. In recent years, as numerical modelers, we learned that we now have the freedom to "discretize" this complex reality and describe it as an ensemble of small homogeneous boxes of continuous media, each of which can have different properties. How do we use this freedom? Is there a need for it? If the answer is "yes," how can we assign different rock-property values to thousands or even millions of such little boxes in our models, to best represent reality, and include confidence levels for each selected rock property? As a tribute to Professor Eugene S. Simpson, with whom the first author of this paper often discussed these questions, we present an overview of three techniques that focus on one property, the rock permeability. We explain the motivation for describing spatial variability and illustrate how to do so by the geostatistical method, the Boolean method, and the genetic method. We discuss their advantages and disadvantages and indicate their present state of development. This is an active field of research and space is limited, so the review is certain to be incomplete, but we hope that it will encourage the development of new ideas and approaches. Résumé On sait depuis longtemps que les propriétés des roches en profondeur sont éminemment variables dans l'espace. On sait que cette variabilité est due à la complexité extrême et à la variation au cours du temps des processus responsables de la formation de la croûte terrestre, de la tectonique des plaques à l'érosion, au transport sédimentaire et au dépôt, sans oublier les effets mécaniques, climatiques et de diagenèse. En tant que géologues, nous avons appris a "lire" cette histoire complexe au sein des roches, et à tenter d'extrapoler dans l'espace notre compréhension. En tant que physiciens, nous avons ensuite appris que pour étudier les écoulements dans de tels milieux, nous devions appliquer les concepts de la mécanique des milieux continus. En tant que mathématiciens utilisant des méthodes analytiques pour résoudre les problèmes d'écoulement, nous avons de plus appris que nous devions simplifier cette réalité complexe en un très petit nombre d'unités, tels que les aquifères et les aquitards, dont chacune est décrite par des propriétés équivalentes constantes. Enfin, dans les années récentes, en tant que numériciens, nous avons appris que nous avions désormais la liberté de "discrétiser" cette réalité complexe, et de la décrire comme un ensemble de petites "boîtes" homogènes de milieu continu, chacune d'entre elles pouvant avoir des propriétés différentes. Comment utilisons nous cette liberté nouvellement acquise? En avons-nous réellement besoin? Si la réponse est "oui", comment pouvons nous attribuer des propriétés différentes aux roches des milliers ou même millions de petites "boîtes" dans nos modèles, pour représenter au mieux la réalité, et comment déterminer les intervalles de confiance des propriétés choisies pour chaque roche? En hommage au Professeur Eugène S. Simpson, avec lequel le premier auteur de cet article a eu souvent l'occasion de discuter de ces questions, nous présentons ici un survol général de quelques techniques de génération de telles propriétés se focalisant sur une seule d'entre elles, la perméabilité des roches. Nous expliquons d'abord quels sont les raisons qui engagent à tenter de décrire la variabilité spatiale, puis nous illustrons trois méthodes pour le faire, la méthode géostatistique, la méthode Booléenne et la méthode génétique. Nous présentons leurs avantages et inconvénients respectifs, et donnons l'état actuel de leur développement. Ces méthodes constituant un domaine de recherche actif, et la place étant ici limitée, ce survol est nécessairement incomplet, mais nous espérons qu'il encouragera l'essor de nouvelles idées et de nouvelles approches. Resumen Sabemos desde hace tiempo que las propiedades del subsuelo son altamente variables espacialmente.

Como geólogos, hemos aprendido a "leer" esta compleja historia en las rocas y a cómo tratar de extrapolar en el espacio lo que ya sabemos. Como físicos, aprendimos después que para estudiar los procesos en este tipo de medios debemos aplicar las leyes de la mecánica de los medios continuos. Como matemáticos que usan métodos analíticos, hemos aprendido que debemos simplificar el medio dividiéndolo en un número menor de unidades, como serían los acuíferos y acuitardos, y describiendo sus propiedades mediante valores equivalentes (constantes). En los últimos años, como modelistas, también hemos aprendido que tenemos la libertad de "discretizar" esta realidad compleja y describirla como un conjunto de pequeñas cajas homogéneas de medio continuo, cada una con propiedades diferentes. ¿Cómo usamos esta libertad?¿Tenemos necesidad de ella? Si la respuesta es "sí", ¿cómo podemos asignar valores de las distintas propiedades de las rocas a miles e incluso millones de estas pequeñas cajas en nuestros modelos, con la pretensión de representar la realidad, y a la vez dar intervalos de confianza para cada propiedad seleccionada? Como un tributo al Profesor Eugene S. Simpson, con quien el autor de este artículo a menudo discutió sobre estas cuestiones, se presenta una recopilación de tres técnicas que se centran en una propiedad, la permeabilidad de la roca. Se explica la motivación para describir la variabilidad espacial y se ilustra cómo hacerlo mediante el método geoestadístico Booleano y mediante el método genético. Para cada método se discuten sus ventajas e inconvenientes y se indica su estado actual de desarrollo. Se trata éste de un campo activo de investigación y el espacio es limitado, por lo que la revisión es incompleta, pero esperamos que pueda servir para animar el desarrollo de nuevas ideas.

  7. Upset Simulation and Training Initiatives for U.S. Navy Commercial Derived Aircraft

    NASA Technical Reports Server (NTRS)

    Donaldson, Steven; Priest, James; Cunningham, Kevin; Foster, John V.

    2012-01-01

    Militarized versions of commercial platforms are growing in popularity due to many logistical benefits in the form of commercial off-the-shelf (COTS) parts, established production methods, and commonality for different certifications. Commercial data and best practices are often leveraged to reduce procurement and engineering development costs. While the developmental and cost reduction benefits are clear, these militarized aircraft are routinely operated in flight at significantly different conditions and in significantly different manners than for routine commercial flight. Therefore they are at a higher risk of flight envelope exceedance. This risk may lead to departure from controlled flight and/or aircraft loss1. Historically, the risk of departure from controlled flight for military aircraft has been mitigated by piloted simulation training and engineering analysis of typical aircraft response. High-agility military aircraft simulation databases are typically developed to include high angles of attack (AoA) and sideslip due to the dynamic nature of their missions and have been developed for many tactical configurations over the previous decades. These aircraft simulations allow for a more thorough understanding of the vehicle flight dynamics characteristics at high AoA and sideslip. In recent years, government sponsored research on transport airplane aerodynamic characteristics at high angles of attack has produced a growing understanding of stall/post-stall behavior. This research along with recent commercial airline training initiatives has resulted in improved understanding of simulator-based training requirements and simulator model fidelity.2-5 In addition, inflight training research over the past decade has produced a database of pilot performance and recurrency metrics6. Innovative solutions to aerodynamically model large commercial aircraft for upset conditions such as high AoA, high sideslip, and ballistic damage, as well as capability to accurately account for scaling factors, is necessary to develop realistic engineering and training simulations. Such simulations should significantly reduce the risk of departure from controlled flight, loss of aircraft, and ease the airworthiness certification process. The characteristics of commercial derivative aircraft are exemplified by the P-8A Multi-mission Maritime Aircraft (MMA) aircraft, and the largest benefits of initial investigation are likely to be yielded from this platform. The database produced would also be utilized by flight dynamics engineers as a means to further develop and investigate vehicle flight characteristics as mission tactics evolve through the years ahead. This paper will describe ongoing efforts by the U.S. Navy to develop a methodology for simulation and training for large commercial-derived transport aircraft at unusual attitudes, typically experienced during an aircraft upset. This methodology will be applied to a representative Navy aircraft (P-8A) and utilized to develop a robust simulation that should accurately represent aircraft response in these extremes. Simulation capabilities would then extend to flight dynamics analysis and simulation, as well as potential training applications. Recent evaluations of integrated academic, ground-based simulation, and in-flight upset training will be described along with important lessons learned, specific to military requirements.

  8. Trauma and violence in the Wari empire of the Peruvian Andes: warfare, raids, and ritual fights.

    PubMed

    Tung, Tiffiny A

    2007-07-01

    This study examines bioarchaeological evidence for violence during the period of Wari imperialism in the Peruvian Andes through analysis of skeletal trauma from three populations dating to AD 650-800. The samples are from contemporaneous archaeological sites: Conchopata, a Wari heartland site in central highland Peru; Beringa, a community of commoners in the Majes valley of the southern Wari hinterland; and La Real, a high status mortuary site, also in the Majes valley. Given the expansionist nature of Wari and its military-related iconography and weaponry, it is hypothesized that Wari imperialism was concomitant with greater levels of violence relative to other prehispanic groups in the Andes. It is also hypothesized that differential articulation with the Wari empire (e.g., heartland vs. hinterland groups) affected the frequency and patterning of trauma. Results show that cranial trauma frequency of the three Wari era samples is significantly greater than several other Andean skeletal populations. This suggests that Wari rule was associated with high levels of violence, though it may not have always been related to militarism. The three adult samples show similar frequencies of cranial trauma (Conchopata = 26%; Beringa = 33%; La Real = 31%). This may suggest that differential positioning in the Wari empire had little effect on exposure to violence. Sex-based differences in cranial trauma frequencies are present only at La Real, but wound patterning differs between the sexes: females display more wounds on the posterior of the cranium, while males show more on the anterior. These data suggest that Wari rule may have contributed to violence. PMID:17506491

    Background The epidemic of gender-based violence in the Democratic Republic of the Congo (DRC) has garnered popular media attention, but is incompletely described in the medical literature to date. In particular, the relative importance of militarized compared to civilian rape and the impact on vulnerable populations merits further study. We describe a retrospective case series of sexual abuse among children and youth in eastern DRC. Methods Medical records of patients treated for sexual assault at HEAL Africa Hospital, Goma, DRC between 2006 and 2008 were reviewed. Information extracted from the chart record was summarized using descriptive statistics, with comparative statistics to examine differences between pediatric (≤18 yrs) and adult patients. Findings 440 pediatric and 54 adult sexual abuse cases were identified. Children and youth were more often assaulted by someone known to the family (74% vs 30%, OR 6.7 [95%CI 3.6–12], p<0.001), and less frequently by military personnel (13% vs 48%, OR 0.14 [95%CI 0.075–0.26], p<0.001). Delayed presentation for medical care (>72 hours after the assault) was more common in pediatric patients (53% vs 33%, OR 2.2 [95%CI 1.2–4.0], p = 0.007). Physical signs of sexual abuse, including lesions of the posterior fourchette, hymeneal tears, and anal lesions, were more commonly observed in children and youth (84% vs 69%, OR 2.3 [95%CI 1.3–4.4], p = 0.006). Nine (2.9%) pediatrics patients were HIV-positive at presentation, compared to 5.3% of adults (p = 0.34). Interpretation World media attention has focused on violent rape as a weapon of war in the DRC. Our data highlight some neglected but important and distinct aspects of the ongoing epidemic of sexual violence: sexual abuse of children and youth. PMID:21267467

  10. Cost effective, weight sensitive design for military airborne electronic systems

    SciTech Connect

    Peck, W.M.

    1996-12-31

    Thermal management of Military airborne electronic systems is governed by many trade-offs. While the trade-offs may change depending on the customer and system requirements, minimizing weight is usually the primary engineering concern because it saves aircraft fuel. Fuel savings provides increased range and time aloft for the aircraft. The most common approach to achieving meaningful reductions in equipment weight is to reduce system volume. Reduced volume is achieved by increasing electronic packaging density which is accomplished by incorporating new materials, processes, and technologies into the system design. The following four considerations are currently under study in the development of an 8 KW high altitude Military electronic system in order to reduce system volume: (1) identifying design parameters and performing trade-off studies between the use of liquid vs. forced air for system cooling; (2) modeling the total system thermal resistance path to identify possible areas for reducing component temperature rise in order to provide enhanced system reliability; (3) substituting commercial plastic integrated circuits (ICs) for Mil ceramic components to reduce material cost while still meeting system requirements; and (4) using TC1050 material technology in: Militarizing Commercial Off The Shelf (COTS) Circuit Card Assemblies (CCAs), developing high conductivity ceramic packaging for Multi Chip Modules (MCMs), and for developing low coefficient of thermal expansion (CTE) composites for use at both the chip and chassis level. Current results from these studies have yielded a design that has a 2:1 reduction in system volume and a weight reduction of 480 lbs from a currently fielded system.

  11. The Mathematical Courses of Pedro Padilla and Étienne Bézout: Teaching Calculus in Eighteenth-Century Spain and France

    NASA Astrophysics Data System (ADS)

    Blanco, Mónica

    2013-04-01

    The aim of this paper is to provide a cross-national comparative analysis of the introduction of calculus in Spanish and French military educational institutions through the works of Pedro Padilla y Arcos (1724-1807?) and Étienne Bézout (1730-1783), respectively. Both authors developed their educational work in the context of military schools and academies. Padilla's Curso Militar de Mathematicas (1753-1756) was the first work published in Spain which introduced the teaching of calculus in formal education. Bézout's Cours de Mathématiques (1764-1769) was the first work on calculus explicitly addressed to French military students and can be considered a representative of the canonical knowledge on eighteenth-century mathematics, both in France and abroad. Eighteenth-century Spain has traditionally been regarded as a country in the periphery whose scientific culture and education were pervaded by French science and education. This centre-periphery framework is often represented by a static model of one-way transmission from the centre to the periphery. A crossnational comparative analysis can help revisit this monolithic centre-periphery framework. A recent historiographical stream places the emphasis on appropriation, hence moving away from the idea of passive reception. In my paper I focus on the reading and writing of educational books, as practices which contribute actively to the development and circulation of knowledge. To assist the analysis, I explore the differences in communication practices in each case, in contents and approaches, and in particular, I give special attention to their inspiration in mathematical streams other than the French standpoint.

  12. [The boycott against German scientists and the German language after World War I].

    PubMed

    Reinbothe, R

    2013-12-01

    After the First World War, the Allied academies of sciences staged a boycott against German scientists and the German language. The objective of the boycott was to prevent the re-establishment of the prewar dominance of German scientists, the German language and German publications in the area of international scientific cooperation. Therefore the Allies excluded German scientists and the German language from international associations, congresses and publications, while they created new international scientific organizations under their leadership. Medical associations and congresses were also affected, e. g. congresses on surgery, ophthalmology and tuberculosis. Allied physicians replaced the "International Anti-Tuberculosis Association" founded in Berlin in 1902 with the "Union Internationale contre la Tuberculose"/"International Union against Tuberculosis", founded in Paris in 1920. Only French and English were used as the official languages of the new scientific organizations, just as in the League of Nations. The boycott was based on the fact that the German scientists had denied German war guilt and war crimes and glorified German militarism in a manifesto "To The Civilized World!" in 1914. The boycott first started in 1919 and had to be abolished in 1926, when Germany became a member of the League of Nations. Many German and foreign physicians as well as other scientists protested against the boycott. Some German scientists and institutions even staged a counter-boycott impeding the resumption of international collaboration. The boycott entailed an enduring decline of German as an international scientific language. After the Second World War scientists of the victorious Western Powers implemented a complete reorganization of the international scientific arena, based on the same organizational structures and language restrictions they had built up in 1919/1920. At the same time scientists from the U.S.A. staged an active language and publication policy, in order to establish the dominance of English in the international scientific arena. PMID:24343188

  13. Origins of the New Latino Underclass

    2012-01-01

    Over the past four decades, the Latino population of the United States was transformed from a small, ethnically segmented population of Mexicans in the southwest, Puerto Ricans in New York, and Cubans in Miami into a large national population dominated by Mexicans, Central Americans, and South Americans. This transformation occurred through mass immigration, much of it undocumented, to the point where large fractions of non-Caribbean Hispanics lack legal protections and rights in the United States. Rising illegality is critical to understanding the disadvantaged status of Latinos today. The unauthorized population began to grow after avenues for legal entry were curtailed in 1965. The consequent rise in undocumented migration enabled political and bureaucratic entrepreneurs to frame Latino migration as a grave threat to the nation, leading to a rising frequency of negative framings in the media, a growing conservative reaction, and increasingly restrictive immigration and border policies that generated more apprehensions. Rising apprehensions, in turn, further enflamed the conservative reaction to produce even harsher enforcement and more still more apprehensions, yielding a self-feeding cycle in which apprehensions kept rising even though undocumented inflows had stabilized. The consequent militarization of the border had the perverse effect of reducing rates of out-migration rather than inhibiting in-migration, leading to a sharp rise in net undocumented population and rapid growth of the undocumented population. As a result, a majority of Mexican, Central American, and South American immigrants are presently undocumented at a time when unauthorized migrants are subject to increasing sanctions from authorities and the public, yielding down-ward pressure on the status and well-being of Latinos in the United States.

  14. Single Stage to Orbit: Politics, Space Technology, and the Quest for Reusable Rocketry

    2003-01-01

    While the glories and tragedies of the space shuttle make headlines and move the nation, the story of the shuttle forms an inseparable part of a lesser-known but no less important drama-the search for a re-useable single-stage-to-orbit rocket. Here an award-winning student of space science, Andrew J. Butrica, examines the long and tangled history of this ambitious concept, from it first glimmerings in the 1920s, when technicians dismissed it as unfeasible, to its highly expensive heyday in the midst of the Cold War, when conservative-backed government programs struggled to produce an operational flight vehicle. Butrica finds a blending of far-sighted engineering and heavy-handed politics. To the first and oldest idea-that of the reusable rocket-powered single-stage- to-orbit vehicle-planners who belonged to what President Eisenhower referred to as the military-industrial complex added experimental (" X "), "aircraft-like" capabilities and, eventually, a "faster, cheaper, smaller" managerial approach. Single Stage to Orbit traces the interplay of technology, corporate interest, and politics, a combination that well served the conservative space agenda and ultimately triumphed-not in the realization of inexpensive, reliable space transport-but in a vision of space militarization and commercialization that would appear settled United States policy in the early twenty-first century. "The 'holy grail' of the spaceship movement has been the development of a vehicle that could accomplish single stage to orbit (SSTO) flight. This study describes the evolution of this concept from the 192'0s to the present, revealing a conservative space agenda that has not yet been the subject of historical analysis. As such, it makes an important contribution to space history literature."-Roger D. Launius, The Smithsonian Institution.

    From Roman gladiatorial combat to Egyptian animal mummies, the capture and manipulation of carnivores was instrumental in helping to shape social hierarchies throughout the ancient world. This paper investigates the historical inflection point when humans began to control animals not only as alimental resources but as ritual symbols and social actors in the New World. At Teotihuacan (A.D. 1-550), one of the largest pre-Hispanic cities, animal remains were integral components of ritual caches expressing state ideology and militarism during the construction of the Moon and the Sun Pyramids. The caches contain the remains of nearly 200 carnivorous animals, human sacrificial victims and other symbolic artifacts. This paper argues the presence of skeletal pathologies of infectious disease and injuries manifest on the carnivore remains show direct evidence of captivity. Stable isotope analysis (δ13C and δ15N) of bones and teeth confirms that some of these carnivores were consuming high levels of C4 foods, likely reflecting a maize-based anthropocentric food chain. These results push back the antiquity of keeping captive carnivores for ritualistic purposes nearly 1000 years before the Spanish conquistadors described Moctezuma's zoo at the Aztec capital. Mirroring these documents the results indicate a select group of carnivores at Teotihuacan may have been fed maize-eating omnivores, such as dogs and humans. Unlike historical records, the present study provides the earliest and direct archaeological evidence for this practice in Mesoamerica. It also represents the first systematic isotopic exploration of a population of archaeological eagles (n = 24) and felids (n = 29). PMID:26332042

  16. "Clutching a knifeblade": human rights and development from Asian women's perspective.

    PubMed

    Sancho-liao, N

    1993-06-01

    A brief, vivid portrait of the human rights conditions for women in Asia was presented: "kapit sa patalim" or utter despair, urban migration, export processing zones, tourism and prostitution, political repression, and military sexual slavery. Advocates of women's human rights for Asian women must contend with patriarchal and male-dominated systems that oppress and exploit women to a much greater extent than men. Liberation from these systems and the domination and exploitation by wealthier nations must be a goal of a new economic world order. Unjust and repressive structures must be destroyed, and equitable distribution of wealth and democracy and popular initiatives promoted. The status of women must be raised to coequal status with men. The most important objective of human rights advocates should be the empowerment of women at the individual, community, national, regional, and international level. The Asian Women's Human Rights Council was established as an addition to 3 already operating regional commissions of women's organizations. The aim was not just to describe women as victims, but to pressure development activity to account for women's human rights. Sex tribunals have been scheduled between 1993 and 1994 to address the following issues: 1) sex trafficking (Japan, May 1993); 2) violence against women (Pakistan, December 1993); 3) militarism, environment, and violence against women (Korea, March 1994); 4) crimes of development against women in Asia (India); 5) religion and violence against women (Malaysia, 1994); and 6) indigenous women (December 1994). Women were victims when Filipino domestic workers were stranded and raped in Iraq during the chaos of war, when girls from landless peasant families migrated near Clark Air Force Base to earn a living as prostitutes for US servicemen, when women were forced to work 36-hour shifts in foreign-owned garment factories in Bataan, when women migrated for work, and when women were abused and battered in Bangladesh and India. Many other examples of abuse were indicated in the discussion. PMID:12345217

    We propose a dislocation model for the two normal faulting earthquakes that struck the central Apennines (Umbria-Marche, Italy) on 1997 September 26 at 00:33 (Mw 5.7) and 09:40 GMT (Mw 6.0). We fit coseismic horizontal and vertical displacements resulting from GPS measurements at several monuments of the IGMI (Istituto Geografico Militare Italiano) by means of a dislocation model in an elastic, homogeneous, isotropic half-space. Our best-fitting model consists of two normal faults whose mechanisms and seismic moments have been taken from CMT solutions; it is consistent with other seismological and geophysical observations. The first fault, which is 6 km long and 7 km wide, ruptured during the 00:33 event with a unilateral rupture towards the SE and an average slip of 27 cm. The second fault is 12 km long and 10 km wide, and ruptured during the 09:40 event with a nearly unilateral rupture towards the NW. Slip distribution on this second fault is non-uniform and is concentrated in its SE portion (maximum slip is 65 cm), where rupture initiated. The 00:33 fault is deeper than the 09:40 one: the top of the first rupture is deeper than 1.7 km the top of the second is 0.6 km deep. In order to interpret the observed epicentral subsidence we have also considered the contributions of two further moderate-magnitude earthquakes that occurred on 1997 October 3 (Mw 5.2) and 6 (Mw 5.4), immediately before the GPS survey, and were located very close to the 09:40 event of September 26. We compare the pattern of vertical displacements resulting from our forward modelling of GPS data with that derived from SAR interferograms: the fit to SAR data is very good, confirming the reliability of the proposed dislocation model.

    Violence is a serious public health and human rights challenge with global psychosocial impacts across the human lifespan. As a middle-income country (MIC), South Africa experiences high levels of interpersonal, self-directed and collective violence, taking physical, sexual and/or psychological forms. Careful epidemiological research has consistently shown that complex causal pathways bind the social fabric of structural inequality, socio-cultural tolerance of violence, militarized masculinity, disrupted community and family life, and erosion of social capital, to individual-level biological, developmental and personality-related risk factors to produce this polymorphic profile of violence in the country. Engaging with a concern that violence studies may have reached something of a theoretical impasse, 'second wave' violence scholars have argued that the future of violence research may not lie primarily in merely amassing more data on risk but rather in better theorizing the mechanisms that translate risk into enactment, and that mobilize individual and collective aspects of subjectivity within these enactments. With reference to several illustrative forms of violence in South Africa, in this article we suggest revisiting two conceptual orientations to violence, arguing that this may be useful in developing thinking in line with this new global agenda. Firstly, the definition of our object of enquiry requires revisiting to fully capture its complexity. Secondly, we advocate for the utility of specific incident analyses/case studies of violent encounters to explore the mechanisms of translation and mobilization of multiple interactive factors in enactments of violence. We argue that addressing some of the moral and methodological challenges highlighted in revisiting these orientations requires integrating critical social science theory with insights derived from epidemiology and, that combining these approaches may take us further in understanding and addressing the recalcitrant range of forms and manifestations of violence.

  20. The population problem is not just about people.

    The increasing numbers of human beings on the planet and decreasing acres of forests and decreasing numbers of species in the world are straightforward, but they stimulate bitter and unresolved disagreements. Population growth will stop either through contraceptive use or naturally. Population growth is not the main cause for environmental destruction. Control of the land and other resources by the privileged few, militarism, corporate irresponsibility, and misplaced development priorities are responsible for it. Antiabortion groups have now entered the debate which causes apprehensive policymakers to not be able to differentiate population or family planning (FP) from abortion. In the US, the Bush administration does not support most international FP activities yet young US Representative Bush from Texas supported these activities. Some environmentalists view the population problem as a result of environmental differences between the North and the South. Only 20% of the population live in the North yet they consume 80% of the world's resources and produce 80% of its waste. Even though most of the population growth is in the South, 30 countries have reduced growth rates through effective FP. Yet the population in 90 countries will increase 2-fold in 30 years. The coercive, and insensitive to women's needs population program in India has not been able to reduce population growth. About 500 million in India want to stop childbearing, but do not have the education or the means to stop. In Thailand and Indonesia where most women are literate, birth rates have fallen, however. Thus the President of the Population Institute encourages the US to increase funding for international FP projects to US$500 million/year. One woman notes that if women really did have the freedom over childbearing, the population problem would not exist. PMID:12343823

    The prevalence of carbon monoxide intoxication in the World shows that this is a common situation. In Portugal, there are no concrete data available in literature and its incidence remains unknown. Currently, the use of hyperbaric oxygen is a valid therapeutic for carbon monoxide poisoning management. However, its effectiveness and its proper handling are still controversial. The first aim of this study was to estimate the incidence of carbon monoxide intoxication in Portugal and to analyze its demographic characteristics. The second objective of this work was to evaluate the possible change in the type of treatment applied in areas near de hyperbaric chamber of Unidade Local de Saúde de Matosinhos, since its opening in June 2006. To achieve these objectives, we conducted a survey on admissions data for carbon monoxide intoxication occured between January first, 2000 and December 31, 2007. These data was collected in seven hospitals and in the Administração Central do Sistema de Saúde, I.P. Nationally, 621 hospitalizations were recorded, which represents an incidence of 5,86/100000 in 8 years. In the seven hospitals, there were 93 hospitalizations due to carbon monoxide intoxication during the same period of time. There was a peak of incidence during winter, between November and March and there was a similar distribution in men (47,3%) and women (52,7%). Since June 2006, date of opening of the hyperbaric chamber, the Unidade Local de Saúde de Matosinhos, E.P.E. recorded a sharp increase in the number of hospitalization for carbon monoxide intoxication. The number of admissions in the 19 months after the chamber opening was double the number of all cases occurred in that institution in the 65 months prior. We concluded that, in Portugal, carbon monoxide intoxication is an uncommon situation but it´s still an important cause of hospitalization. The referral of cases to the Unidade Local de Saúde de Matosinhos, E.P.E. since the opening of hyperbaric chamber objectively increased. Thus, we can assume that peripheral hospitals are aware of the existence of hyperbaric chamber and its potential in treatment of carbon monoxide poisoning. PMID:22525624

    The increased incidence of Imported Tropical Diseases in Portugal is correlated to a recent higher standard of living, influence of media and a consequent expansion of tourism, and above all to the close relationship existing between Portugal and Africa. The number and pathology (parasitic diarrhoeas, protozoal and helminthic infections) of in-patients with Tropical Diseases at the Unidade de Doenças Infecciosas, Parasitárias e de Medicina Tropical (UDIP-MT) were described, with special emphasis on Malaria (155 in-patients during the period from 1989 to 1993) and on Sleeping Sickness, where Eflornitin (DFMO) was for the first time used in Portugal. Finally, the impact of HIV epidemic on incidence and different clinical presentations of parasitic and other tropical pathology was also evaluated. PMID:9005704

    Febrile neutropenia is a well-known entity in children with cancer, being responsible for the high risk for infection that characterizes this population. For this reason, cancer patients are hospitalized so that they can receive prophylactic care. Risk factors have been used to classify patients at a high risk for developing bacteremia. The present study evaluates whether those risk factors (C-reactive protein, hypotension, leukemia as the cancer type, thrombocytopenia, recent chemotherapy, and acute malnutrition) apply to patients at the Unidad Nacional de Oncología Pediátrica. We evaluated 102 episodes in 88 patients, in whom risk factors and blood cultures were tested. We observed no statistical relationship between the six risk factors and bacteremia. There was also no relationship between bacteremia and the simultaneous presence of two, three, or more risk factors. A significant relationship of C-reactive protein and platelet count with other outcome factors was observed. PMID:20404980

    The final results of a Sistema Interamericano de Metrologia (SIM) interlaboratory comparison on microphone calibration are presented. Initially the comparison involved NORAMET countries: USA, Canada, and Mexico. Later, the comparison was extended to include Argentina and Brazil, resulting in a SIM AUV.A-K1 microphone interlaboratory comparison. The National Metrology Institutes (NMIs) of the five American countries that participated were the Institute for National Measurement Standards (INMS--Canada), National Institute of Standards and Technology (NIST--USA), Centro Nacional de Metrologia (CENAM--Mexico), Instituto Nacional de Metrologia, Normalizacao e Qualidade Industrial (INMETRO--Brazil) and Unidad Tecnica Acustica, (INTI--Argentina). INMS, Canada was the pilot laboratory that provided the data for the final report. The maximum rms deviation for the two LS1P laboratory standard microphones measured by the above participants is 0.037 dB that may be considered as the key comparison reference value.

    The first airborne laser altimetry measurements of a glacier in South America are presented. Data were collected in November of 2001 over Glaciar Tyndall, Torres del Paine National Park, Chilean Patagonia, onboard a Twin Otter airplane of the Chilean Air Force. A laser scanner with a rotating polygon-mirror system together with an Inertial Navigation System (INS) were fixed to the floor of the aircraft, and used in combination with two dual-frequency GPS receivers. Together, the laser-INS-GPS system had a nominal accuracy of 30 cm after data processing. On November 23rd, a total of 235 km were flown over the ablation area of Glaciar Tyndall, with 5 longitudinal tracks with a mean swath width of 300 m, which results in a point spacing of approximately 2 m both along and across track. A digital elevation model (DEM) generated using the laser altimetry data was compared with a DEM produced from a 1975 map (1:50,000 scale — Instituto Geográfico Militar (IGM), Chile). A mean thinning of - 3.1 ± 1.0 m a - 1 was calculated for the ablation area of Glaciar Tyndall, with a maximum value of - 7.7 ± 1.0 m a - 1 at the calving front at 50 m a.s.l. and minimum values of between - 1.0 and - 2.0 ± 1.0 m a - 1 at altitudes close to the equilibrium line altitude (900 m a.s.l.). The thinning rates derived from the airborne survey were similar to the results obtained by means of ground survey carried out at ˜ 600 m of altitude on Glaciar Tyndall between 1975 and 2002, yielding a mean thinning of - 3.2 m a - 1 [Raymond, C., Neumann, T.A., Rignot, E., Echelmeyer, K.A., Rivera, A., Casassa, G., 2005. Retreat of Tyndall Glacier, Patagonia, over the last half century. Journal of Glaciology 173 (51), 239-247.]. A good agreement was also found between ice elevation changes measured with laser data and previous results obtained with Shuttle Radar Topography Mission (SRTM) data. We conclude that airborne laser altimetry is an effective means for accurately detecting glacier elevation changes in Patagonia, where an ice thinning acceleration trend has been observed during recent years, presumably in response to warming and possibly also drier conditions.

    High thinning rates (up to - 4.0 ± 0.97 m a - 1 ) have been measured at Campo de Hielo Patagónico Norte (CHN) or Northern Patagonia Icefield, Chile between 1975 and 2001. Results have been obtained by comparing a Digital Elevation Model (DEM) derived from regular cartography compiled by Instituto Geográfico Militar of Chile (IGM) based upon 1974/1975 aerial photographs and a DEM generated from Advanced Space-borne Thermal Emission and Reflection Radiometer (ASTER) satellite images acquired in September 2001. A complete cloud-free Landsat ETM+ satellite image mosaic acquired in March 2001 was used to update the available glacier inventory of the CHN, including all glaciers larger than 0.5 km 2 (48 new glaciers). A new delineation of ice divides was also performed over the accumulation areas of glaciers sharing the high plateau where the existing regular cartography exhibits poor coverage of topographic information. This updated glacier inventory produced a total ice area for 2001 of 3953 km 2, which represents a decrease of 3.4 ± 1.5% (140 ± 61 km 2 of ice) with respect to the total ice area of the CHN in 1979 calculated from a Landsat MSS satellite image. Almost 62% of the total area change between 1979 and 2001 took place in glaciers located at the western margin of the CHN, where the maximum area loss was experienced by Glaciar San Quintín with 33 km 2. At the southern margin, Glaciar Steffen underwent the largest ice-area loss (12 km 2 or 2.6% of the 1979 area), whilst at the eastern margin the greatest area loss took place in Glaciares Nef (7.9 km 2, 5.7% of the 1979 area) and Colonia (9.1 km 2, 2.7% of the 1979 area). At the northern margin of the CHN the lower debris-covered ablation area of Glaciar Grosse collapsed into a new freshwater lake formed during the late 1990s. The areal changes measured at the CHN are much larger than previously estimated due to the inclusion of changes experienced in the accumulation areas. The CHN as a whole is contributing melt water to global sea level rise at rates ˜ 25% higher than previous estimates.

  16. The 79 AD eruption of Somma: The relationship between the date of the eruption and the southeast tephra dispersion

    NASA Astrophysics Data System (ADS)

    Rolandi, G.; Paone, A.; Di Lascio, M.; Stefani, G.

    Somma-Vesuvius is a composite volcano on the southern margin of the Campanian Plain which has been active during the last 39 ka BP and which poses a hazard and risk for the main population center situated around its base. The fieldwork and data analysis on which this report is based are related to the eight Plinian eruptions that have occurred in the last 25 ka. For six of these eruptions, the fallout products were dispersed to the east-northeast, whereas deposits from the 25 ka Codola and AD 79 eruptions were dispersed in a south-easterly direction. During the AD 79 eruption, in particular, the dispersal axis migrated from the east-southeast to south-southeast. New high level wind data collected at the weather stations of the Aereonautica Militare data centres at Pratica di Mare (Rome) and Brindisi have been compiled to characterize the prevailing wind condition in the Somma-Vesuvius region. The common north-easterly dispersal directions of the Plinian eruptions are consistent with the distribution of ash by high-altitude winds from October to June. In contrast, the south-easterly trend of the AD 79 products appears to be anomalous, because the eruption is conventionally believed to have occurred on the 24th of August, when its southeast dispersive trend falls in a transitional period from the Summer to Autumnal wind regimes. In fact, the AD 79 tephra dispersive direction towards the southeast is not in agreement with the June-August high-altitude wind directions that are toward the west. This poses serious doubt about the date of the eruption and the mismatch raises the hypothesis that the eruption occurred in the Autumnal climatic period, when high-altitude winds were also blowing towards the southeast. New archaeological findings presented in this study definitively place the date of eruption in the Autumn, in good agreement with the prevailing high-altitude wind directions above Somma-Vesuvius. Moreover, wind data and past eruptive behaviour indicate that a future subplinian-Plinian eruption at Somma-Vesuvius has a good chance to occur when winds are blowing toward the eastern sectors (northeast-southeast), in the Autumnal-Winter period, and only a slightest chance in Summer, when winds are blowing toward the west, depositing ash fallout on the Neapolitan community.

    Se presenta un estudio espectroscópico y polarimétrico de la binaria eclipsante AR Pavonis a partir de observaciones obtenidas con el telescopio de 2.15 m. del CASLEO (San Juan). El estudio de la naturaleza del sistema se realizó a través del análisis de algunos espectros reunidos entre los años 1990 y 1995 y de datos polarimétricos correspondientes al intervalo 1995 y 1997. El análisis espectroscópico indica que AR Pav está compuesta por una gigante roja M3.7 y una componente caliente compacta, con una temperatura mayor a 90000 K y una luminosidad del orden de 500Lsolar. A lo largo del período orbital, las variaciones observadas en flujo y en velocidades radiales, reflejan que las emisiones permitidas se forman en una región que rodea la componente caliente. El estudio de la polarización lineal de AR Pav indica que además de una componente interestelar, existe una componente intrínseca del sistema que varía temporalmente y con la longitud de onda de la luz polarizada. El distinto comportamiento del grado de polarización y del ángulo de posición observado en fases diferentes, sugiere que distintos mecanismos pueden estar actuando, dependiendo de la región de scattering observado a lo largo de la línea de la visual.

    Small interfering RNAs (siRNAs) are short, double-stranded RNAs that use the endogenous RNAi pathway to mediate gene silencing. Phosphorylation facilitates loading of a siRNA into the Ago2 complex and subsequent cleavage of the target mRNA. In this study, 2', 3' seco nucleoside modifications, which contain an acylic ribose ring and are commonly called unlocked nucleic acids (UNAs), were evaluated at all positions along the guide strand of a siRNA targeting apolipoprotein B (ApoB). UNA modifications at positions 1, 2 and 3 were detrimental to siRNA activity. UNAs at positions 1 and 2 prevented phosphorylation by Clp1 kinase, abrogated binding to Ago2, and impaired Ago2-mediated cleavage of the mRNA target. The addition of a 5'-terminal phosphate to siRNA containing a position 1 UNA restored ApoB mRNA silencing, Ago2 binding, and Ago2 mediated cleavage activity. Position 1 UNA modified siRNA containing a 5'-terminal phosphate exhibited a partial restoration of siRNA silencing activity in vivo. These data reveal the complexity of interpreting the effects of chemical modification on siRNA activity, and exemplify the importance of using multiple biochemical, cell-based and in vivo assays to rationally design chemically modified siRNA destined for therapeutic use.
