Neoliberal policies and urban reconfigurations. Victoria, San Fernando, province of Buenos Aires, a city understood from theory

Full Text Available This article aims to explain from a theoretical conceptual approach the particularities that exist in Victoria, San Fernando, Buenos Aires, from its urban production. Through a series of field works, semi-structured interviews and observations, it was possible to perceive that in this locality, there are three logics of city production, market, state and necessity, according to Abramo, P. (2002. The post-development cities of Latin America, a space in which constant tensions are generated that alter the harmonious development of daily life and the interaction of those who inhabit the area. On the other hand, it is also perceived that the inhabitants naturalize that way of life, their spatial disposition, the progressive privatization of public areas and the proliferation of closed housing estates. Here is a quote that we have heard repeatedly in interviews with the neighbors: "No one in Victoria gives a ball to anyone." At the moment of understanding Victoria from the theory, we take into account such concepts as the "heterotopy" of Foucault M. (1967 - understood as the juxtaposition of spaces that would be incompatible -the term "com-fusa city" (Abramo P. - as an urban structure that interweaves two traditional models (the Mediterranean compact and the Anglo-Saxon diffused, the notion of "privatopia" by I.Rodriguez Chumillas (2005 and E. Mckenzie (1994 as private spatial consolidation, and finally the concepts: informative and dual cities of R Castells (1995 terms that emerge from the process of globalization, which may be useful to think about the reality of Victoria .

However, they soughed to become independent of them by initiating a policy of creolisation, which would rapidly inflate the allocation of manpower in their estates.

Para adquirir a la abundante mano de obra servil necesaria al desarrollo de las potencialidades de sus haciendas, los jesuitas del colegio de San Pablo de Lima, entre 1691 y 1729, además de acudir al insuficiente mercado local, se valieron de los servicios de mercaderes de confianza, relacionados con los representantes de los asientos negreros en Panamá y luego en Buenos Aires.

Se acompaña de unos breves apuntes donde explicamos y contextualizamos su formación como artista y cómo comienza a tomar contacto con esta actividad, junto a algunos datos de su evolución y referencias a sus obras más señeras. Para seguidamente ir analizando algunas de ellas, incidiendo en el diseño de carteles, murales, carpetas de grabado, proyectos de esculturas, intercalando del mismo modo referencias a su producción editorial donde encontramos reflexiones en cuanto a concepción de diseño se refiere. En este análisis de su obra y cómo fue concebida, remarcamos su vertiente comunicativa y cómo consigue transmitir ciertos valores e ideas o proponer ciertos conceptos. Así, según el punto de vista de Cayetano Aníbal, el diseño es el producto de las capacidades y exigencias de la mente para reflejar, explicar, comunicar y transformar los entornos y los contextos. Terminamos con una reflexión de cómo debiera ser el diseño y el proceso mental por el que un artista debe enfrentarse a la concepción de una obra de arte.

Kamrowska-Zaluska, Dorota

2017-10-01

This paper is introducing Buenos Aires’ achievements and challenges in implementing comprehensive development and integrating efficient and sustainable transport system within its urban structure. There are several important steps in this process starting from urban regeneration of Puerto Madero, the introduction and then implementation of a strategic plan Modelo territorial (2010) and of Buenos Aires’ Plan de Movilidad Sustentable (2013). The last one - Sustainable Mobility Plan helped Buenos Aires win several prestigious rewards for innovative approach to mobility and sustainable transport and leadership in combating climate change. Buenos Aires City government demonstrates strong leadership by implementing well-planned (Bus Rapid Transport) BRT solutions, stressing the importance of political will and support, flexibility and an open mind in listening to the points of view of all stakeholders involved. Buenos Aires has made a very important step toward sustainability by supporting development of more sustainable modes of transport, such as bicycle-sharing system and improving walkability of the city centre. The last initiative combined with strong focus on public spaces is adding to tourist attractiveness based on diversity of the capital of Argentina.

Public works: Building a Monument to Modern Buenos Aires

Anayvelyse Allen-Mossman

2016-12-01

Full Text Available Understanding the relationship between the project of modernity and urbanism has been key to understanding the city of Buenos Aires’ material transformations throughout the 20th century. This paper considers how thinking about the issues of modernity and urbanism from the perspective of monuments--namely, the Obelisk of Buenos Aires--sheds new light on how elements of this modernizing project were undertaken and how its material markers have been used and manipulated, and modified through their representation in cultural discourse on the city. Rethinking Buenos Aires from the Obelisk implies literally thinking from underground, from the subway lines that form its base and transform it into a popular symbol of mobility.

To celebrate the 60th anniversary of Medicina (Buenos Aires) an International Symposium was held at the National Academy of Medicine of Buenos Aires on the 6-7th of October 1999, under the title of Clinical investigation in the next millennium. This meeting was a success as evidenced by the 376 registered attendants. Sixty years of uninterrupted publication is an uncommon feat in our midst and this could be achieved on the basis of a number of factors which include, the initiative of those who founded the journal, the unfailing motivation and dedication of the Editorial Board and primarily the authors who have trusted us with their manuscripts. Of the many important papers published, we have selected a few which proved to be milestones in the development of Argentine biomedicine. It is to be hoped that the future will bring an increase in our impact index through more and even better papers eventually reflecting the authentic scientific value of our country.

Lead pollution present in atmospheric aerosols in the city Buenos Aires was measured in 1989, using Heavy Ion PIXE. Since then, environmental conditions have changed significantly. The usage of unleaded gasoline was introduced, and the utilisation of compressed natural gas as car fuel has increased. Recently, a new sampling campaign of atmospheric aerosols has started, partly in collaboration with the Greenpeace Foundation. The present studies reveal that lead pollution in Buenos Aires has significantly decreased since 1989. The concentrations of other elements are determined as well. (author)

Full Text Available El artículo aborda la problemática de la gestión de los residuos sólidos domiciliarios de la Ciudad de Buenos Aires. Dicha gestión está regulada por un marco jurídico muy antiguo que impide la recuperación o el reciclaje en casi todas las fases del circuito de recolección, transporte y disposición final. En forma paralela a la gestión oficial, se ha extendido una vía de recolección y recuperación informal, que ha llevado a cabo algunas personas pertenecientes a los sectores más pobres de nuestra sociedad, quienes encuentran en la venta de los residuos recuperados un camino para su supervivencia diaria. En el presente artículo describimos las características de este circuito informal en la Ciudad de Buenos Aires, las rutas, calles, horarios y tipos de residuos recogidos, y analizamos el fenómeno no solamente como una manifiestación de la pobreza, sino como un camino alternativo para la recolección diferenciada de los residuos sólidos de la ciudad.

To describe the demographic and clinical aspects of hepatic fascioliasis as well as the complications and associations between various factors and the disease in a reference hospital. This is a descriptive and retrospective case series study; we included all patients who had a recent diagnosis of hepatic fascioliasis from 2003 to 2010 in the Hospital Nacional Cayetano Heredia. Demographic and clinical variables were analyzed including complications and treatment received. 68 medical records were found eligible for the study. The mean age was 36 years. Ancash department was the most frequent place of origin and residence. Most of them were diagnosed in the chronic phase, the most common symptom was abdominal pain and eight patients had complications: 3 hepatic abscess, 1 subcapsular hematoma, 1 cholangitis and 1 cholangitis plus cholecystitis. There were the following associations: Age under 15 years with chronic phase and hyporexia, being a student with a positive stool analysis; and between being born in an endemic area with the absence of complications. Hepatic fascioliasis has unspecific clinical presentation so the epidemiological or dietary history and specially eosinophilia should guide the diagnosis.

En este estudio se analizó a 9 pacientes con NAC por Legionella pneumophila atendidos entre 1997 y 2001 en el Hospital de Clínicas José de San Martín de la Universidad de Buenos Aires. Se registraron datos de antecedentes, enfermedad actual, contactos, exposición laboral, examen físico, pruebas de laboratorio y uso previo de antibióticos, y se tomó en cuenta la presencia de criterios de gravedad. Nueve pacientes presentaron diagnóstico de NAC por Legionella, ninguno refirió antecedentes de viajes recientes; cuatro de ellos debieron ser internados en unidades de cuidado intensivo. Siete pacientes tenían antecedentes de tabaquismo, 4 tenían EPOC y un paciente linfoma no-Hodgkin. Nuestra casuística corrobora la baja especificidad de la clínica y estudios complementarios para predecir esta etiología. El aislamiento de Legionella es dificultoso, la seroconversión permite el diagnóstico retrospectivo y requiere plazos prolongados y el antígeno urinario aporta un diagnóstico inmediato. Cuando la legionelosis aparece en casos aislados, como ocurriría en Argentina, si no se piensa en esta etiología no se llegará al diagnóstico.

En el presente trabajo se utilizó el concepto de Necesidades Básicas Insatisfechas (NBI como criterio de pobreza y se aplicó un paradigma cognitivo de funcionamiento ejecutivo proveniente de la Neurociencia. El mismo plantea el análisis de componentes de comportamientos inteligentes orientados hacia objetivos y asociados a la activación de circuitos cerebrales que involucran centralmente a la región prefrontal. Se comparó el desempeño ejecutivo de 247 niños escolarizados de 3 a 5 años de edad, provenientes de hogares pobres (NBI y no pobres o con Necesidades Básicas Satisfechas (NBS, y de jardines de infantes del Distrito Escolar 4 de la Ciudad de Buenos Aires (Boca-Barracas y de distritos escolares de Vicente López y San Isidro del Gran Buenos Aires (Argentina.

Los resultados obtenidos muestran perfiles de desempeño diferentes entre ambos grupos. El perfil de desempeño menos eficiente en términos de las variables estudiadas se observó en el grupo de niños proveniente de hogares pobres. Estos resultados constituyen un aporte significativo de un paradigma neurocientífico para la implementación de estrategias de intervención orientadas a estimular el funcionamiento cognitivo de tipo ejecutivo de niños de edad preescolar.

Full Text Available This paper discusses the first medical associations in Buenos Aires, between 1852 and 1880. The main characteristic of the very first association, the Asociación Médica Bonaerense, was its ambivalent attitude in regards to doctor's and professor's elitism. Following the decline of this association, due to the creation of the Academia de Medicina de Buenos Aires, its more pugnacious facet was retaken by the Círculo Médico Argentino, who attempted to unite both students and young teacher's interests aims.

Tras su declive, consecuencia de la creación de la Academia de Medicina de Buenos Aires, el impulso asociativo fue retomado por el Círculo Médico Argentino, que recuperó su faceta más impugnadora e intentó aunar los intereses de estudiantes y profesores jóvenes.

The content of Fe, Mg, Al, Mn, Zn, Pb, Ba, Cr, Hg, Cu, Ni, Cd and Sb was determined by inductively coupled plasma atomic emission spectrometry (ICP-OES in Morus alba tree bark collected in the cities of Buenos Aires and Mendoza. The main air pollutants detected in the Buenos Aires urban area were Ba, Cr, Cu and Ni and indicate significative difference from the Mendoza urban and periurban areas. Significantly, higher concentrations of Zn, Ba, Cr and Cu were recorded in the periurban area of the city of Buenos Aires than in Mendoza. Bark samples were strongly influenced by dust and show Al, Fe, Mg and other element accumulations that indicate that soil particles were carried out by wind. Elements like Ba and Zn, commonly linked to traffic emissions, showed the highest concentrations in the Buenos Aires metropolitan area, possibly due to more intensive vehicular traffic. Our results indicated that intensity of vehicular traffic and not city structure is responsible for air pollution.Um estudo comparativo dos elementos depositados nas cascas das árvores foi realizado nas áreas urbanas e na periferia de duas cidades das mais importantes da Argentina.

Melanie Klein in Buenos Aires: beginnings and developments.

In the first decades of the 20th century, Freud was known and quoted in Latin America by an elite of enlightened minds. In the 1940s a convergence took place in Buenos Aires of European exiles with local pioneers, and thus the Argentine Psychoanalytical Association was founded in 1942. Since then psychoanalysis has grown steadily and has spread into hospitals and universities, influencing culture at large. The socioeconomic situation of that time permitted this phenomenon to develop, to the astonishment of observers. In this paper the authors study the strong influence of Kleinian thought during the first 30 years of this development. The original works of local thinkers constitute the intellectual capital that sustains the idea of an 'Argentine psychoanalytic school'. During the 1970s, both society and psychoanalysis endured deep and complex changes. Lacan's teachings gained support and Klein's influence began to decline. At present the Buenos Aires Kleinians keep working, while their relationship with Lacanians and other schools is calmer. Respectful discussions became thus possible, oriented to strictly scientific differences.

To do this, we will analyze the political and economic context in which contraband arose and gained importance in order to reflect whether this economic practice -conducted by government officials, vecinos (official residents and settlers of the port of Buenos Aires- can be considered corrupt in the context of the period studied. We will situate the behavior of these social actors within an intertwined complex of political beliefs and ideologies, and conjunctures, to explain how a practice like colonial-era contraband has multiple, tightly related causes.

Research is a main element for human and social development. Under this point of view, it involves particular challenges and opportunities for the so-called "developing countries". An approach for those challenges and opportunities comes from the analysis of two interrelated activities; the training of new researchers and the research development with institutions or researchers which are external to the institution ("collaborative research"). Both activities are essential for the consolidation, widening and updating of the institutional capabilities for scientific production. We present here the experiences of the Instituto de Medicina Tropical "Alexander von Humboldt" of the Universidad Peruana Cayetano Heredia, in relation to the training of new researchers, we discuss the four elements we consider key for this process; the promotion of stimulating environments for research, the proactive identification of fellows, the complementary advice and networks consolidation; and we analyze three successful models of international collaboration for the training of new researchers under different institutional approaches.

The five sheets of the San Francisco folio the Tamalpais, Ban Francisco, Concord, Ban Mateo, and Haywards sheets map a territory lying between latitude 37° 30' and 38° and longitude 122° and 122° 45'. Large parts of four of these sheets cover the waters of the Bay of San Francisco or of the adjacent Pacific Ocean. (See fig. 1.) Within the area mapped are the cities of San Francisco, Oakland, Berkeley, Alameda, Ban Rafael, and San Mateo, and many smaller towns and villages. These cities, which have a population aggregating about 750,000, together form the largest and most important center of commercial and industrial activity on the west coast of the United States. The natural advantages afforded by a great harbor, where the railways from the east meet the ships from all ports of the world, have determined the site of a flourishing cosmopolitan, commercial city on the shores of San Francisco Bay. The bay is encircled by hilly and mountainous country diversified by fertile valley lands and divides the territory mapped into two rather contrasted parts, the western part being again divided by the Golden Gate. It will therefore be convenient to sketch the geographic features under four headings (1) the area east of San Francisco Bay; (2) the San Francisco Peninsula; (3) the Marin Peninsula; (4) San Francisco Bay.

Analizaremos los dilemas entre sus dimensiones artística y política, en las que se encarna la contraposición que él mismo establece entre la Tradición y la Historia de un pueblo con personalidad cultural propia que reivindica como nación. Finalmente, comprobaremos cómo se desarrollan discursivamente estas tensiones en su pieza oratoria más importante, “Alba de Gloria”.

Se analiza el concepto y su uso. Se explica la legislación ejidal bonaerense y se describe la implementación de las leyes desamortizadoras en España, México y Buenos Aires para tratar problemas comunes. Por último, se confrontan los objetivos de la legislación con la forma en que se aplicó en Buenos Aires y en un caso en particular, el ejido de Mercedes. Los resultados de la legislación liberal se explican en el proceso histórico de interacción entre las leyes, su aplicación local y los intersticios ya que en estos cobra importancia la relación de los sujetos sociales entre sí y las instituciones estatales encargadas de llevar adelante el proceso de reforma.The present work studies the redefinition civil assets propriety rights, specifically the ejidos, from a comparative perspective, analyzing the concept and its use.

This article describes the study carried out on a series of oil paintings on canvas from the eighteenth century that were restored at Centro de Produccion e Investigacion en Restauracion y Conservacion Artistica y Bibliografica - Tarea (CEIRCAB-Tarea), Buenos Aires, Argentina: the San Pedro Gonzalez Telmo Sibyls. Experimental study was undertaken to identify inorganic pigments and the technique used in their confection; and, in this way, try to add information about their local origin. Therefore special emphasis was put to infer technologies used in the manufacturing of these paintings. Elemental analysis was performed by total reflection X-ray fluorescence spectrometry (TXRF) and complemented by optical and polarized light microscopy. Microsampling was carefully done over areas of the paintings which were damaged and where a small additional loss will not be noticed. This investigation has shown that a variety of pigments were used, namely earth pigments (red and yellow ochres), white lead, vermilion, etc., and they were used either pure or in mixtures. This characterization helped conservators in their decisions regarding a better understanding of the deterioration processes. In addition, this research about the material composition allowed the art historians and restorers the possibility to obtain information about where, when or by whom The San Pedro Gonzalez Telmo Sibyls may have been painted.

To validate the score AIMS65 in patients with upper gastrointestinal bleeding, in terms of mortality and rebleeding a 30-day event. Patients included were those with higher age to 18 years attending the Hospital Nacional Cayetano Heredia during the period May 2013 to December 2014, by upper gastrointestinal bleeding. Data were analyzed using ROC curve (Receiver Operating Characteristic) and the area was obtained under the curve (AUC) to properly qualify the score AIMS65. 209 patients were included, 66.03% were male, with an average age of 58.02 years. The mortality rate was 7.65%, the multiorgan failure the most common cause of death. Plus 3.82% of the patients had recurrent bleeding and 11% required a transfusion of more than 2 units of blood. When analyzing the ROC curve with AIMS65 and mortality score a value of 0.9122 is reported; identifying it as cutoff greater than or equal to 3 value in the score AIMS65 to discriminate patients at high risk of death, likewise the ROC curve was analyzed for recurrence of bleeding with a value of 0.6266 and the need to Transfusion of packed red blood cells over two a value of 0.7421. And it was determined the average hospital stay with a value of 4.8 days, however, no correlation was found with the score AIMS65. AIMS65 score is a good predictor of mortality, and is useful for predicting the need for transfusion of more than 2 globular packages. However it is not a good predictor for recurrence of bleeding, or hospital stay.

In Facultad de Ciencias Exactas y Naturales,Universidad de Buenos Aires there is a service called Servicio de Identificación de Hongos Tóxicos, directed by researchers of the Program of Medicinal Plants and Fungi Involved in Biological Degradation (PROPLAME-PRHIDEB, CONICET) that assist hospitals and other health establishments, identifying the different samples of fungi and providing information about their toxicity, so that patients can receive the correct treatment. The objective of the present study was to analyze all the cases received from 1985 to 2012. This analysis permitted the confection of a table identifying the most common toxic species. The information gathered revealed that 47% of the patients were under 18 years of age and had eaten basidiomes; the remaining 53% were adults who insisted that they were able to distinguish edible from toxic mushrooms. Chlorophyllum molybdites turned out to be the main cause of fungal intoxication in Buenos Aires, which is commonly confused with Macrolepiota procera, an edible mushroom. In the second place Amanita phalloides was registered, an agaric known to cause severe symptoms after a long period of latency (6-10 hours), and which can lead to hepatic failure even requiring a transplant to prevent severe internal injuries or even death, is not early and correctly treated.

This qualitative study of low-income mothers in Buenos Aires, Argentina, examines the influence of socio-economic conditions, organizational structures, family relationships, and food insecurity on child feeding practices and weight status. Thirty-eight mothers of preschool children living in urban Buenos Aires participated in four focus group discussions. The results indicated that many mothers were aware that obesity may be detrimental to the child's health, but most of them are unclear about the specific consequences. Maternal employment, family pressures, food insecurity and financial worries seem to influence child feeding practices. These findings have important implications for developing strategies for nutritional assistance that could benefit the health of children and provide opportunities for educational programs that are directed to nutritional awareness in Buenos Aires, Argentina. The right to eat regularly and properly is an obligation of the State and must be implemented taking into account the notion of food sovereignty and respecting the importance of preserving the culture and eating habits of a country and its diverse population groups.

Full Text Available El present trabajo tiene como objetivo principal caracterizar el medio físico de las áreas costeras, con el fin determinar los impactos en la hidrodinámica litoral, a mediano y corto plazo, generado por la explotación de arena de playa en las principales localidades costeras de la provincia de Buenos Aires, entre cabo San Antonio y Necochea. Para tal fin se describen las explotaciones mineras de mayor magnitud llevadas a cabo a lo largo de la costa de la provincia de Buenos Aires y se analiza su efecto para cada morfología costera. En todos los casos las explotaciones han ocasionado un deficit de arena en la corriente de deriva litoral, lo que hace que la erosión se traslade como una onda en el sentido de la deriva litoral, es decir hacia el norte para estas costas. El tipo de costa que recibe el impacto de esta onda condiciona el grado de erosión a la que este sujeta. En costas acantiladas cohesivas las explotaciones han producido un importante incremento en las tasas de retroceso de los acantilados y pérdida de playa. En costas definidas como de tipo B (con desarrollo de bermas los efectos erosivos de la explotacíon, sumados a otros factores antrópicos, han afectado fundamentalmente las morfologías de playa, mientras que en las de tipo A (sin desarrollo de bermas, el efecto no solo ha alcanzado la playa sino que también ha provocado retoceso de la línea de costa. Asimismo de determinó que las tasas de retroceso de la costa se aceleran o retardan en igual medida durante la explotación y recuperación respectivamente; es decir que la recuperación por interrupción de las actividades mineras es semejante en magnitud a la erosión inducida durante la explotación.

SANS (Small Angle Neutron Scattering) is a popular method for elucidation of nano-scale structures. However science continually challenges SANS for higher performance, prompting exploration of ever-more exotic and expensive technologies. We propose a compact high resolution SANS, using very cold neutrons, magnetic focusing lens and a wide-angle spherical detector. This system will compete with modern 40 m pinhole SANS in one tenth of the length, matching minimum Q, Q-resolution and dynamic range. It will also probe dynamics using the MIEZE method. Our prototype lens (a rotating permanent-magnet sextupole), focuses a pulsed neutron beam over 3-5 nm wavelength and has measured SANS from micelles and polymer blends. (authors)

Revitalización de subcentros metropolitanos. Buenos Aires entre la ciudad dispersa y la ciudad compacta / Revitalization of metropolitan subcentres. Buenos Aires between the dispersed city and the compact city

Full Text Available Las grandes ciudades latinoamericanas se debaten actualmente entre dos procesos de transformación socio-territorial convergentes: la densificación y verticalización de las áreas centrales, y la expansión cada vez más difusa y fragmentada de los suburbios. Esta dicotomía entre ciudad compacta y ciudad dispersa parece mostrar procesos singulares en el caso de la región metropolitana de Buenos Aires. A partir de los años dos mil, se han ralentizado los nuevos lanzamientos de urbanizaciones cerradas y, paralelamente, han comenzado a manifestarse algunos casos de revitalización de antiguas subcentralidades del sur de la metrópolis, que habían entrado en una fase de estancamiento y deterioro desde mediados de los años setenta, y actualmente experimentan una aceleración de la producción de vivienda multifamiliar de calidad. Este trabajo explora y muestra algunas experiencias concretas de esta tendencia, con la hipótesis que, al menos en Buenos Aires, los procesos de transformación y reestructuración metrolitana muestran complejidades y diversidades según los contextos temporales y territoriales que se analicen. The large Latin American cities are currently experiencing two convergent socio-territoria transformation processes: the densification and verticalization of central areas, and the increasingly diffuse and fragmented suburban expansion. This dichotomy between the compact city and the dispersed city seems to show unique features in the case of the metropolitan region of Buenos Aires. After the 2000s, the expansion of gated communities has slowed down and at the same time some old subcentralities in the South of the metropolis have begun to revitalize. Since the mid-1970s, they had entered a phase of stagnation and deterioration, and at present the production of quality multifamily housing is rapidly growing. This paper reflects on this trend and show some concrete experiences. Our hypothesis is that in Buenos Aires the process

Full Text Available El presente artículo se propone indagar en los órdenes normativos, círculos de sociabilidad y dispositivos institucionales a los cuales los actores apelaban para interactuar económica y comercialmente en Buenos Aires durante la primera mitad del siglo XVII. Recurriendo al endeudamiento interpersonal como observatorio, se avanzará en la comprensión de la práctica consistente en formalizar legalmente, ante el escribano, las obligaciones derivadas de las deudas. Mediante este abordaje se intentará indagar en el peso que las redes de parentesco detentaron como uno de los órdenes normativos e institucionales posibles para la interacción económica del temprano Río de la Plata.This article aims to investigate the normative orders, sociability circles and institutional arrangements that actors used for their economic and commercial interaction during the first half of the 17th century in Buenos Aires. By studying interpersonal borrowing as observatory, we will advance in understanding the practice of registering the debts with the notary. Through this approach we will try to investigate the actual weight of the interpersonal networks as one of the institutional and normative contexts available for economic interaction in the early Rio de la Plata.

Territorios del tango en Buenos Aires: aportes para una historia de sus formas de inscripción

Urban territories are defined by a complex geography that includes not only the space and its features but also the styles, manners and ways of life of the social groups that take part of and compose it. In the same way, is either possible to speak about musical expressions without consider the atmosphere in which they arise and developed. This implies that a phenomenon like music, specially when it is understood as a performance, a scene and a practice, is framed in defined temporal and spatial axis. That means that music expresses an historical time and –at the same time– a specific geography. There are few cities with a so defined and recognized musical identity as Buenos Aires. The tango is the music of a shaped space, in which cultural traditions and a transforming territory are articulated. Thus, tango implies Buenos Aires and Buenos Aires implies tango. This work describes the territories of the tango throughout its history, showing its geographical migrations around the city and the consequent appropriations and resignifications experimented.

Hepatitis C virus diversification in Argentina: comparative analysis between the large city of Buenos Aires and the small rural town of O'Brien.

Marcelo D Golemba

Full Text Available BACKGROUND: The estimated prevalence of HCV infection in Argentina is around 2%. However, higher rates of infection have been described in population studies of small urban and rural communities. The aim of this work was to compare the origin and diversification of HCV-1b in samples from two different epidemiological scenarios: Buenos Aires, a large cosmopolitan city, and O'Brien, a small rural town with a high prevalence of HCV infection. PATIENTS AND METHODS: The E1/E2 and NS5B regions of the viral genome from 83 patients infected with HCV-1b were sequenced. Phylogenetic analysis and Bayesian Coalescent methods were used to study the origin and diversification of HCV-1b in both patient populations. RESULTS: Samples from Buenos Aires showed a polyphyletic behavior with a tMRCA around 1887-1900 and a time of spread of infection approximately 60 years ago. In contrast, samples from ÓBrien showed a monophyletic behavior with a tMRCA around 1950-1960 and a time of spread of infection more recent than in Buenos Aires, around 20-30 years ago. CONCLUSION: Phylogenetic and coalescence analysis revealed a different behavior in the epidemiological histories of Buenos Aires and ÓBrien. HCV infection in Buenos Aires shows a polyphyletic behavior and an exponential growth in two phases, whereas that in O'Brien shows a monophyletic cluster and an exponential growth in one single step with a more recent tMRCA. The polyphyletic origin and the probability of encountering susceptible individuals in a large cosmopolitan city like Buenos Aires are in agreement with a longer period of expansion. In contrast, in less populated areas such as O'Brien, the chances of HCV transmission are strongly restricted. Furthermore, the monophyletic character and the most recent time of emergence suggest that different HCV-1b ancestors (variants that were in expansion in Buenos Aires had the opportunity to colonize and expand in O'Brien.

Full Text Available El objetivo del trabajo es estimar la precipitación estival en la ciudad y Gran Buenos Aires. Para ello fue correlacionada con los campos de temperatura de la superficie del mar, las alturas geopotenciales en 1000 hPa, 500 hPa y 200 hPa, la presión a nivel del mar, viento en 850 hPa y humedad específica en niveles bajos en el mes previo. Predictores fueron seleccionados basándose en la significancia estadística, la independencia y la explicación física de su relación y utilizados como variables de entrada para generar una regresión lineal múltiple con el método "forward stepwise". Ellos son la altura geopotencial de 1000 hPa sobre la costa del océano Atlántico alrededor de 25ºS y el viento zonal en el centro de América del Sur. La lluvia estival depende principalmente del debilitamiento del anticiclón del Atlántico y de la advección de aire húmedo desde el norte del país. La verificación se realizó para los datos del período 1984-2007 obteniendo una correlación entre la serie observada y estimada de 0.61. La estabilidad del modelo se probó con la metodología de la crossvalidación. Los resultados indican la existencia de predictabilidad para la precipitación estival para el área de Buenos Aires.The aim of this study is to estimate December to February rainfall in Buenos Aires city and its surroundings, using atmospheric variables.

Genetic and phenotypic variability of iris color in Buenos Aires population

Directory of Open Access Journals (Sweden)

Diana María Hohl

Full Text Available Abstract The aim of this work was to describe the phenotypic and genotypic variability related to iris color for the population of Buenos Aires province (Argentina, and to assess the usefulness of current methods of analysis for this country. We studied five Single Nucleotide Polymorphisms (SNPs included in the IrisPlex kit, in 118 individuals, and we quantified eye color with Digital Iris Analysis Tool. The markers fit Hardy-Weinberg equilibrium for the whole sample, but not for rs12913832 within the group of brown eyes (LR=8.429; p=0.004. We found a remarkable association of HERC2 rs12913832 GG with blue color (p < 0.01 but the other markers did not show any association with iris color. The results for the Buenos Aires population differ from those of other populations of the world for these polymorphisms (p < 0,01. The differences we found might respond to the admixed ethnic composition of Argentina; therefore, methods of analysis used in European populations should be carefully applied when studying the population of Argentina. These findings reaffirm the importance of this investigation in the Argentinian population for people identification based on iris color.

[Demographic dynamics, migrants from bordering countries and economic activity in Buenos Aires].

1997-04-01

The growth and changes--by age, sex, and place of birth--in the structure of the total population of the Buenos Aires metropolitan area and of the subpopulation over 15 years of age and economically active are analyzed for the decade of the 1980s. Study of the economic participation of migrants and its possible influence on levels of employment or unemployment should be carried out within the framework of changes in the population's structure and economic participation. The 1981 and 1991 censuses and the Permanent Survey of Households were the sources of data. Immigration to Argentina has declined considerably in recent years, but it is still a factor in the population growth of metropolitan Buenos Aires. Between the 1981 and 1991 censuses, the population aged 15 and over grew by 10.9/1000, or a total of 827,806 people. Migrants from bordering countries increased in number (by 85,109, or 10.3%) and in proportion to the total population (from 3.9% to 4.6%). Migrant women increased at the highest rate (30.1/1000). The greatest growth occurred among men aged 40 and over and among women aged 35 and over. The growth of the economically active population over age 15 for different groups of national origin, sex, and age showed much greater heterogeneity. In 1991, women from bordering countries represented 3.8% of all women in metropolitan Buenos Aires but 5.7% of the total economically active female population and nearly 7% of the economically active female population aged 35 and over. Women from neighboring countries were responsible for 10.3% of the growth in the economically active female population aged 30-34 and 40-44 between 1981 and 1991. The absolute and relative increases in migrants from neighboring countries and their greater economic participation tend to increase the general level of economic activity.

Non formal education in the teaching of peruvian dances among peruvian migrants in Buenos Aires

Directory of Open Access Journals (Sweden)

Silvia Benza

2009-12-01

Full Text Available The increasing migration of Peruvian citizens to Buenos Aires is a recent phenomenon, and the intensification of the development of organizations and their public presence are correlated with the participation in festivities, civic organizations and the like. This article is a preliminary report on research that focuses on Peruvian dance groups in Buenos Aires and that proposes to describe some of the ways that Peruvian folkdances are transmitted. I show how a process of non formal education is shaped by the interactions among dance groups and between them and representatives of the Peruvian Government in Buenos Aires; and how it is influenced by the need to «demonstrate through performance,» by ways of participating in the groups and by the previous knowledge of the dances that the performers bring with them. The analysis focuses on the microanalytic dimension of representations and practices of the dancers and directors of the dance groups. The fieldwork was carried out in the period 2005-2008 and focused on four groups of Peruvian folk dancers. The phenomena studied are shown to have great potential as intercultural mediators that transcend cultural manifestations to become mechanisms of consciousness raising that reach out to publics beyond the Peruvians themselves.

A prototype for an integrated system that includes air quality constraints to the procedure that is presently in use to determine the daily economic dispatch of power plants in Argentina is proposed. The recent incorporation of new machines to the installed capacity of the three power plants located in the densely populated metropolitan area of Buenos Aires, the thermal-based future expansion of the power sector and the relatively high nitrogen oxides concentrations that can be associated to electricity generation in the city of Buenos Aires, served to motivate this work. The prototype attempts to generate a dispatch that is compatible with the environment taking into account the present economic dispatch, weather forecast and dispersion models to evaluate ambient air concentrations of nitrogen oxides (NO x ) caused by the combined operation of the thermal power plants. Although the prototype deals exclusively with NO x , since these are the pollutants of primary concern considering the fuel consumption pattern of argentinean power plants, its structure is general enough to take into account other pollutants such as sulfur dioxide and particulate matter.

Buenos Aires, the capital city of Argentina, is surrounded by 24 neighboring districts forming the so-called Buenos Aires metropolitan area (AMBA) that holds a population of 14 million people. In this work, the atmospheric aerosol of this metropolitan area was characterized through the determination of mass concentration, black carbon and elemental concentrations, on PM10 and PM2.5 samples taken using a 'Gent' sampler. The sampling site was located at an urban area characterized by fast and heavy traffic and samples were collected each third day, along 24 hours, between October 2005 and February 2006. A number of elements (As, Ba, Br, Ce, Co, Cr, Cs, Eu, Fe, Hf, La, Na, Rb, Sb, Sc, Se, Sm, Th, Yb and Zn) were determined by Neutron Activation Analysis and their results, as well as those of gravimetric mass concentrations, were compared with historical data. Enrichment factors were calculated for both fractions, using Sc as reference element and Mason's crustal concentration values, showing enrichment for As, Br, Sb, Se and Zn. Although the number of analyzed filters is still small, a preliminary factor analysis was run on both fraction results and different source profiles were found. The attribution of the sources to soil, high temperature processes including refuse incineration, fuel combustion and others, metal processes, traffic and other anthropogenic ones is discussed.

Full Text Available This article analyzes how racial categories are produced and reproduced in Buenos Aires, Argentina’s capital city. To that end, this article focuses on the cases of three Afro-Descendant porteña women who, by local standards, are fully white.  Their stories allow us to explore, in the first place, how categories like “black,” “white,” and others are used and understood in contemporary Buenos Aires and how this use configures two types of blackness (racial blackness and popular blackness and makes it impossible for mestizaje categories to emerge. In the second place, through these cases this article explores how people’s very “ways of being” are at play, creating a discriminatory and oppressive environment for people at risk of not matching the ideal of the nation.

San Marino, an independent republic located in north central Italy, in 1983 had a population of 22,206 growing at an annual rate of .9%. The literacy rate is 97% and the infant mortality rate is 9.6/1000. The terrain is mountainous and the climate is moderate. According to local tradition, San Marino was founded by a Christian stonecutter in the 4th century A.D. as a refuge against religious persecution. Its recorded history began in the 9th century, and it has survived assaults on its independence by the papacy, the Malatesta lords of Rimini, Cesare Borgia, Napoleon, and Mussolini. An 1862 treaty with the newly formed Kingdom of Italy has been periodically renewed and amended. The present government is an alliance between the socialists and communists. San Marino has had its own statutes and governmental institutions since the 11th century. Legislative authority at present is vested in a 60-member unicameral parliament. Executive authority is exercised by the 11-member Congress of State, the members of which head the various administrative departments of the goverment. The posts are divided among the parties which form the coalition government. Judicial authority is partly exercised by Italian magistrates in civil and criminal cases. San Marino's policies are tied to Italy's and political organizations and labor unions active in Italy are also active in San Marino. Since World War II, there has been intense rivalry between 2 political coalitions, the Popular Alliance composed of the Christian Democratic Party and the Independent Social Democratic Party, and the Liberty Committee, coalition of the Communist Party and the Socialist Party. San Marino's gross domestic product was $137 million and its per capita income was $6290 in 1980. The principal economic activities are farming and livestock raising, along with some light manufacturing. Foreign transactions are dominated by tourism. The government derives most of its revenue from the sale of postage stamps to

Vehicular traffic is the main source of platinum group elements (PGEs) in highly populated urban areas like Buenos Aires where a traffic density of 1,500,000 vehicles day{sup -1} (corresponding to 7500 vehicles km{sup -2}) is estimated. Since there is no information on the levels of PGEs in Buenos Aires, a pilot study was undertaken to ascertain the amount of two major PGEs, namely Pt and Rh, in the atmosphere of this city. To this end, 49 samples of PM-10 particulate matter were collected during 7 days in seven representative sampling sites located downtown Buenos Aires and spread over an area of about 30 km{sup 2}. The collection of particulate matter was performed on ash-free glass-fiber filters using high volume samplers with PM-10 sampling heads. Filters loaded with the particulate matter were subjected to microwave (MW)-assisted acid digestion using a combination of HNO{sub 3}, HF and HClO{sub 4}. The resulting solutions were evaporated and then diluted with 0.1 mol l{sup -1} HCl. Analyses were performed by sector field inductively coupled plasma-mass spectrometry (SF-ICP-MS) and special attention was paid to the control of mass interferences. Statistical analysis was performed on the experimental data obtained for the element concentrations taking also into account local meteorological data for the monitored period. The highest concentrations of Pt and Rh were detected at two sites (Hospital Aleman and Casa Rapallini) located in streets with traffic consisting mostly of passenger cars. The Pt content (in pg m{sup -3}) in airborne particulate matter was found to vary from 2.3 to 47.7, with a mean value of 12.9+/-7, and that of Rh from 0.3 to 16.8, with a mean value of 3.9+/-2.8. These concentrations are by far below the levels for which adverse health effects might be expected to occur, i.e., around 100 ng m{sup -3}. On the other hand, monitoring of PGEs should be carried out in a systematic fashion to detect possible dramatic increases from today

Bats are potential reservoirs of many vector-borne bacterial pathogens. The aim of the present study was to detect species of Anaplasma, Ehrlichia, Neorickettsia, Rickettsia, Borrelia and Bartonella in Brazilian free-tailed bats (Tadarida brasiliensis, Molossidae) from Buenos Aires city, Argentina. Between 2012 and 2013, 61 T. brasiliensis from urban areas of Buenos Aires city were studied. The samples were molecularly screened by PCR and sequencing. Five bats (8.2%) were positive to Neorickettsia risticii, one (1.6%) was positive to Rickettsia sp. and three bats (4.9%) to Bartonella sp. For molecular characterization, the positive samples were subjected to amplification and sequencing of a fragment of p51 gene for N. risticii, a fragment of citrate synthase gene (gltA) for Rickettsia genus and a fragment of gltA for Bartonella genus. Phylogenetic tree was constructed using the maximum-likelihood method. Phylogenetic analysis of N. risticii detect in our study revealed that it relates to findings in the USA West Coast; Rickettsia sp. detected is phylogenetically within R. bellii group, which also includes many other Rickettsia endosymbionts of insects; and Bartonella sp. found is related to various Bartonella spp. described in Vespertilionidae bats, which are phylogenetically related to Molossidae. Our results are in accordance to previous findings, which demonstrate that insectivorous bats could be infected with vector-borne bacteria representing a potential risk to public health. Future research is necessary to clarify the circulation of these pathogens in bats from Buenos Aires. Copyright © 2017 Elsevier Ltd. All rights reserved.

Las letras de tango, escritas mayoritariamente por hombres, hablan de ese viaje en clave de condena, y la tuberculosis aparece como la materialización de un castigo para esas mujeres jóvenes que han osado desafiar su lugar en el mundo doméstico y barrial. Así, el tango ofrece a su audiencia no sólo un registro fuertemente moralizante sino también la imagen de una enfermedad que parece ser exclusivo patrimonio femenino cuando, en realidad, se trataba de una enfermedad que afectaba tanto a hombres como a mujeres.

In 1864, Lucio V. Mansilla y José Manuel Estrada created the Círculo Literario in Buenos Aires, Argentina, which endured until 1866. This cultural association shared the same concerns than other contemporary entities, also enacted by other men in the cultural life of Buenos Aires at that time. The Círculo Literario aspired to be an association that could gather politicians and men of culture, from different generations and political factions. The article examines the practices and initiatives of this cultural association, in a moment in which the Argentine culture was conceived as an open field for pioneers. The article evaluates the scope and the limits of this cultural entrepreneurship born outside from the State politics.

After the 2001 economic and political crisis, the energy sectors underwent a major reorganization. For the city this meant growing state intervention in energy supply, private firms and the fixing of energy prices. The resulting evolution does not meet the criteria of energy transition as conceived in Europe, but it highlights the weight of the federal government upon a fragmented metropolis where local actors struggle to find their own spaces of action

Historic time series (1970-2006) emissions of greenhouse gases and air pollutants arising from stationary and mobile combustion sources were estimated at national level for Argentina and at regional level for the metropolitan area of Buenos Aires (MABA). All emissions were estimated using a bottom-up approach following the IPCC good practice guidance. For mobile sources, national emissions include all transport categories. Regional emissions account thus far only for on-road. For national emissions, methodologies and guidance by the IPCC were employed, applying the highest possible tier and using: i)country-specific emission factors for carbon and sulphur and technology-based information for other species, ii)activity data from energy balance series (1970-2007), and iii)complementary information concerning the non-energy use of fuels. Regional emissions in 2006 were estimated in-depth using a technology-based approach for the city of Buenos Aires (CBA) and the 24 neighboring districts composing the MABA. A regional emissions factors database was developed to better characterize Latin American fleets and driving conditions employing COPERT III-IV algorithms and emission factors measured in dynamometers and circulating vehicles in Argentina, Brazil, Chile and Colombia. Past emissions were back estimated from 2005 to 1970 using the best available information, which differs greatly among categories, spatial disaggregation and time periods. The time series of stationary and mobile combustion sources at the national and regional level allowed the identification of distinct patterns. National greenhouse gas emissions in 2006 amounted to ~ 150 million ton CO2-equivalent, 70% of which were contributed by stationary sources. On-road transport was the major contributor within mobile sources (28.1 %). The increasing emissions trends are dominated by on-road transport, agriculture and residential categories while the variability is largely associated with energy industries

A case for historic joint rupture of the San Andreas and San Jacinto faults.

Lozos, Julian C

The San Andreas fault is considered to be the primary plate boundary fault in southern California and the most likely fault to produce a major earthquake. I use dynamic rupture modeling to show that the San Jacinto fault is capable of rupturing along with the San Andreas in a single earthquake, and interpret these results along with existing paleoseismic data and historic damage reports to suggest that this has likely occurred in the historic past. In particular, I find that paleoseismic data and historic observations for the ~M7.5 earthquake of 8 December 1812 are best explained by a rupture that begins on the San Jacinto fault and propagates onto the San Andreas fault. This precedent carries the implications that similar joint ruptures are possible in the future and that the San Jacinto fault plays a more significant role in seismic hazard in southern California than previously considered. My work also shows how physics-based modeling can be used for interpreting paleoseismic data sets and understanding prehistoric fault behavior.

But this phenomenon does not belong exclusively to the last decades of the last century. Early interventions in the urban coastal fronts began with the discovery of the coast and leisure in the mid-nineteenth century. The discovery of the coast and leisure had been born since the late eighteenth century with the loss of fear of water, the new value given to science and currents of thought of the Enlightenment and the Romanticism of the time, which would Grand Tour of Europe. This assessment of costs is not reached the industrial cities until the last decades of the 1800s. Several European cities had previously coastal walks, but these were not from a planned urban spaces shared with the port and its aim was solely that of a contemplative walk. In Buenos Aires, as in other American cases, the start of the use of the coast and leisure was very early, compared with its parallel in Europe. While in New York and Chicago Fredrick Law Olmsted and Calvert Vaux were imposing a new use of public space and urban nature in contrast to the growth of cities, Domingo Faustino Sarmiento raised the first projects for the Tres de Febrero Park, the first coastal park the city of Buenos Aires. The authorities, architects and engineers who worked on the draft coastal parks saw these spaces as places of opportunity, as horizons for action, being edges of the city provided a special place for the development of public space. From an aesthetic professionals in charge saw the horizon as a scenic attraction, while from the practical side, the waterfront was the edge, so the city and an area of conflict between national and municipal authorities.

Full Text Available The aim of this pilot study was to evaluate if the residents of psychiatry and clinical psychology from the city of Buenos Aires knew any of the existing mental health Clinical Practice and Treatment Guidelines (CPTGs. We asked residents their opinion about CPTGs and, also, if they followed their recommendations in clinical practice. We asked 59 mental health residents (28 physicians and 29 psychologists with different years of clinical training to fill a questionnaire to know their opinion about CPTGs and also if they follow the CPTG recommendations in their clinical practice. We found that 79.31% of residents did not know any CPTG. Eighty percent of the residents who did know any CPTG have a positive opinion about CPTGs. Finally, the American Psychiatric Association Guidelines were the most known CPTGs. The authors emphasize the need for a clinical guidelines diffusion policy in Buenos Aires city and particularly as a clinical and training resource for mental health residents.

Material y Métodos: Se hizo una revisión retrospectiva de sus fichas epidemiológicas e historias clínicas. Se utilizó la clasificación de los Centros de Control de Enfermedades (CDC para infección por el VIH (Estadíos I-IV. Resultados: Se incluyó 236 mujeres, de 17 a 60 años, con una edad media de 30.4 años. El número de mujeres diagnosticadas por año aumentó de 5 en 1989 a 63 en 1996. La vía probable de adquirir la infección fue por relaciones heterosexuales en 212 pacientes (90.2%. Refirieron haber tenido una sola pareja sexual en su vida 113 (47.8%.

Vulnerabilidad energética en la metrópoli de Buenos Aires

Silvina Carrizo

2014-06-01

Full Text Available Argentina declaró el uso racional y la eficacia energética una prioridad nacional, en consonancia con las recomendaciones de la Agencia Internacional de la Energía. Buenos Aires se ha comprometido con varios programas internacionales de preparación al cambio climático. Así a distintas escalas surgen iniciativas para modificar las condiciones y modalidades de aprovisionamiento y consumo energéticos, que revelan la precariedad y vulnerabilidad del sistema y los servicios. Este trabajo presenta una reflexión sobre los cambios que se dan en ese sentido, mostrando los inconvenientes del modelo energético argentino en Buenos Aires y las estrategias o medidas que tienden a revertirlos y a preparar la ciudad para situaciones críticas. En general, se trata de iniciativas que se implementan individual o parcialmente, sin que haya un plan integral promovido a escala colectiva. Las correcciones resultan marginales en el conjunto sin aliviar los problemas que se agravan por el crecimiento vertiginoso de las demandas. Entonces la continuidad del modelo energético argentino basado en hidrocarburos, para abastecer infraestructura que trabaja al límite de su capacidad y servir territorios que no se han preparado para las posibles crisis, explicaría la vulnerabilidad del sistema de abastecimiento metropolitano.

Full Text Available We carried out the first assessment of abundance and distribution of bird pest species (eared dove Zenaida auriculata, monk parakeet Myiopsitta monachus, picazuro pigeon Patagioenas picazuro and spot-winged pigeon P. maculosa in the pampas of Buenos Aires province, Argentina, and analyzed their association with the presence of crops and/or introduced exotic woodlots in the rural landscape. We surveyed 35 transects located along secondary roads. Bird pest abundance was significantly higher at those sites with presence of woodlots (p<0.0001. Species-specific analyses revealed that abundance of both monk parakeet and picazuro pigeon was sensitive to the frequency of woodlots of tall and perennial tree species (Eucalyptus spp.; p<0.001, whereas eared dove abundance increased significantly with the frequency of woodlots composed by short and perennial tree species (Pinus spp., Casuarina spp.; p=0.002. Most bird pest species in the study area are more sensitive to the presence of woodlots rather than to the presence of croplands in the rural landscape. These results have practical implications, suggesting that an effective control of bird pest species in Buenos Aires province could be attained by managing exotic perennial tree species woodlots.

A palace for astronomy in Buenos Aires

Science.gov (United States)

Gangui, Alejandro

2011-06-01

In no other epoch of Western history like in the Middle Ages, cosmology was so key an element of culture and, one way or another, the motion of the heavens ended up impregnating the literature of that time. Among the most noteworthy poets we find Dante Alighieri, who became famous for his Commedia, a monumental poem written roughly between 1307 and his death in 1321, and which the critics from 16th century onwards dubbed Divina. In this and other works, Dante pictures the cosmic image for the world, summing up the current trends of Neoplatonic and Islamic traditions. The Barolo Palace in the city of Buenos Aires is a singular combination of both astronomy and the worldview displayed in Dante's poetic masterpiece. Some links of the Palace's main architectural structure with the three realms of the Comedy have been studied in the past. In this note we consider its unique astronomical flavor, an issue which has not been sufficiently emphasized yet.

Las colecciones analizadas surgieron en el ámbito privado, recolectadas por coleccionistas que las cedieron para dar origen a estos museos. Al mismo tiempo que las colecciones se hacían públicas, los coleccionistas se convirtieron en sus responsables en el rol de directores de las nuevas instituciones. En el contexto de estos museos, los coleccionistas establecieron relaciones institucionales que sirvieron para elaborar estrategias comunes para el ingreso, selección y exhibición de las colecciones arqueológicas, conformando redes solidarias, como la descripta aquí, para el sur de la provincia de Buenos Aires.Through reference to the creation and expansion of municipal museums in the province of Buenos Aires during the 1950s, the article explores some aspects of how archeological collections are compiled. The collections under study came from private hands, having been gathered by collectors who relinquished them so these museums could be formed. At the same time that these collections became public, the collectors themselves became responsible for them in the role of directors of the new institutes. Within this context, the collectors established institutional relations that allowed them to devise common strategies concerning the receipt, selection, and exhibition of archeological collections. The result was the shaping of a network of solidarity in the southern part of Buenos Aires province.

Buenos Aires׳ informal recyclers (cartoneros) confront multiple health hazards in their work. Based in a survey with (n=397) informal recyclers, this study establishes that these workers experience uneven health landscapes as evidenced through their health outcomes, the social determinants of their health, and their living and working environments. I argue that the analytical framework of urban political ecology can provide insights to the ways that the urban environments where cartoneros live and work are socially-constructed phenomena, drawing on concepts of crisis, metabolism, and multi-scalar analyses.

Ambos buscaron arrojar luz frente a la (aun hoy vigente enorme ausencia de información sobre lo ocurrido en los asentamientos en ese momento. En este sentido, el presente trabajo reflexiona sobre el modo en el cual ambas producciones audiovisuales narran la problemática habitacional resultante de los desalojos masivos, la represión, la violencia, las formas de resistencia, las representaciones sobre los villeros en ese contexto y el rol que tuvo la Iglesia católica.

Performance of BATAN-SANS instrument

Energy Technology Data Exchange (ETDEWEB)

Ikram, Abarrul; Insani, Andon [National Nuclear Energy Agency, P and D Centre for Materials Science and Technology, Serpong (Indonesia)

2003-03-01

SANS data from some standard samples have been obtained using BATAN-SANS instrument in Serpong. The experiments were performed for various experimental set-ups that involve different detector positions and collimator lengths. This paper describes the BATAN-SANS instrument briefly as well as the data taken from those experiments and followed with discussion of the results concerning the performance and calibration of the instrument. The standard samples utilized in these experiments include porous silica, polystyrene-poly isoprene, silver behenate, poly ball and polystyrene-poly (ethylene-alt-propylene). Even though the results show that BATAN-SANS instrument is in good shape, but rooms for improvements are still widely open especially for the velocity selector and its control system. (author)

Los resultados del procesamiento de la información litogeoquímica disponible se exponen como mapas geoquímicos patrones para el pronóstico de mineralización sulfurosa (cuprífera y polimetálica. La superposición de éstos con el mapa geológico posibilita apreciar relaciones entre las anomalías litogeoquímicas complejas descubiertas y determinadas secuencias litológicas de la formación San Cayetano, lo cual contribuye favorablemente a corroborar la especialización geoquímica del Distrito Metalogénico Dora-Francisco. Como resultado se proponen sectores de prospección con órdenes de prioridad deferenciadores que responden a la integración de las categorías prospectivas asignadas, la correspondencia con secuencias de la formación San Cayetano favorables para alojar mineralización sulfurosa y la continuidad espacial de las diferentes Unidades de Información Básicas definidas.

A case for historic joint rupture of the San Andreas and San Jacinto faults

OpenAIRE

Lozos, Julian C.

2016-01-01

The San Andreas fault is considered to be the primary plate boundary fault in southern California and the most likely fault to produce a major earthquake. I use dynamic rupture modeling to show that the San Jacinto fault is capable of rupturing along with the San Andreas in a single earthquake, and interpret these results along with existing paleoseismic data and historic damage reports to suggest that this has likely occurred in the historic past. In particular, I find that paleoseismic data...

Drums Cannot be Silenced: candombe and new activist ethos in the public space of Buenos Aires

Directory of Open Access Journals (Sweden)

Eva Lamborghini

2017-08-01

Full Text Available In the past two decades, Buenos Aires has witnessed a surprising growth and popularity of Afro-Latin American cultural practices. Foremost among them, and most visible in the city’s public space, is Afro-Uruguayan candombe. Having spread beyond the Uruguayan immigrant community that contributed to its re-localization in the 1970s, it is nowadays widely part of the youth urban culture along the country. The paper discusses the re-significations following this vigorous development and how it intersects with other social processes of contemporary Argentine society. Focusing on the re-signification of candombe as “resistance”, as performed by a collective of drummers and dancers known as “Los Tambores No Callan” (Drums cannot be silenced, it highlights the connections they establish between this cultural practice and politics as social struggle. It suggests that this cultural practice is part of –and helps shape– new activist ethos in the public space of Buenos Aires, a historically alleged “White” and “European” city.

Turismo urbano en contexto metropolitano: Tigre como destino turístico en el Área Metropolitana de Buenos Aires (Argentina

Directory of Open Access Journals (Sweden)

Rodolfo V. Bertoncello

2016-08-01

Full Text Available This article addresses the issue of the city as tourist destination, specifically in relation to metropolitan configurations and dynamics. The article analyzes a tourist destination -the town of Tigreas part of the Metropolitan Area of Buenos Aires and its incorporation into the so called “Buenos Aires tourist destination”. The role of the tourist resort in the metropolitan context is analyzed beginning with the recognition of the paucity of studies on the subject at this scale. The article focuses on the analysis of the processes that lead to the establishing of the town as a tourist destination, assuming that this character is the result of specific actions to adapt the locality to tourist requirements. This focus questions the widespread approaches that assume the “tourist vocation” of localities as natural.

1974-01-01

The San Marco C-2 spacecraft, now designated San Marco-4, was successfully launched by a Scout vehicle from the San Marco Platform on 18 February 1974 at 6:05 a.m. EDT. The launch occurred 2 hours 50 minutes into the 3-hour window due co low cloud cover at the launch site. All spacecraft subsystems have been checked and are functioning normally. The protective caps for the two U.S. experiments were ejected and the Omegatron experiment activated on 19 February. The neutral mass spectrometer was activated as scheduled on 22 February after sufficient time to allow for spacecraft outgassing and to avoid the possibility of corona occurring. Both instruments are performing properly and worthwhile scientific data is being acquired.

Full Text Available OBJETIVO: Medir la equidad manifestada por los patrones de consumo de medicamentos en el Área Metropolitana de Buenos Aires, Argentina, a la luz de las transformaciones operadas en el mercado farmacéutico argentino después de la desregulación de la economía en 1991. METODOLOGÍA: Se procesaron y analizaron fuentes estadísticas secundarias: se utilizaron dos encuestas domiciliarias que contenían un módulo sobre la utilización de servicios de salud y gastos asociados diseñado por el Ministerio de Salud y aplicado al Área Metropolitana de Buenos Aires en 1989 y 1995. RESULTADOS: Se constató un aumento del carácter socialmente regresivo del gasto de bolsillo en medicamentos entre 1989 y 1995, en un mercado farmacéutico que ha duplicado sus precios medios en el nuevo contexto de liberación de precios y apertura de las importaciones. Esta regresión se manifestó en el crecimiento del gasto directo de la compra de medicamentos, el aumento de la parte correspondiente a los medicamentos en la estructura del gasto privado para la salud y el incremento desigual del peso relativo de dicho gasto en los ingresos familiares. CONCLUSIONES: El gasto de bolsillo en medicamentos resulta un indicador eficiente de equidad financiera para el estudio de la protección de la población urbana argentina frente al riesgo de enfermar, y puede contribuir a la adecuación del marco regulador del mercado farmacéutico, mediante la incorporación de criterios sociales de evaluación a la ecuación farmacológica de seguridad y eficacia terapéutica.OBJECTIVE: To assess the level of equity in drug consumption patterns in the Metropolitan Area of Buenos Aires, Argentina, given the transformation of the Argentine pharmaceutical market since the deregulation of the country's economy in 1991.

Vezzani Darío

2001-01-01

Full Text Available Cemeteries with many water-filled containers, flowers, sources of human blood, and shade are favorable urban habitats for the proliferation of Aedes aegypti, a vector of yellow fever and dengue. A total of 22,956 containers was examined in the five cemeteries of the city of Buenos Aires, Argentina. The vector was found in four cemeteries that showed an average infestation level of 5.5% (617 positive out of 11,196 water-filled containers. The four cemeteries positive for Ae. aegypti showed significantly different (p<0.01 infestation levels. Vegetation cover and percentage of infestation were significantly correlated (p<0.01, but neither cemetery area nor number of available containers were significantly related to the proportion of positive vases. Our results suggest that the cemeteries of Buenos Aires represent a gradient of habitat favorableness for this vector species, some of which may act as foci for its proliferation and dispersal.

The number of publications in the scientific literature coming from an institution is an indicator of its scientific production. The scientific production of the hospitals of the Government of the City of Buenos Aires (GCBA) has been evaluated previously, but without discriminating how much of that production corresponded to other academic institutions settled there (University of Buenos Aires, UBA, National Council of Scientific Research and Techniques, CONICET). Our objective was to evaluate the publications included in PubMed that correspond to hospitals of the GCBA, describe their main characteristics, and discriminate the contribution of other academic institutions (UBA and CONICET). It is a cross-sectional study based on a PubMed search, using the name of each of the 34 GCBA hospitals, CONICET and UBA in the "affiliation" field. In total, 2727 publications from GCBA hospitals were identified (4.6% of Argentine publications); 73.9% in English, 78.9% in relation to humans, 37.2% in the last 5 years; 6.4% with high level of evidence (clinical trials and meta-analysis), and 28.4% including children. Compared to the national total, the GCBA publications include fewer works in English, more research in humans, more clinical trials and more research in children. Of the publications corresponding to hospitals of the GCBA, 90.4% did not share the affiliation with CONICET or with UBA. In conclusion, the GCBA hospitals generated 4.6% of the total Argentine publications in PubMed; and 90% of these was not shared with UBA or CONICET. Publications from GCBA institutions include more clinical trials and research in children.

2000-01-01

Biomonitors were used as part of a pollution study of Buenos Aires city atmosphere under the International Atomic Energy Agency Research Contract ARG 7251, from the Co-ordinated Research Programme on Applied Research on Air Pollution using Nuclear Related Analytical Techniques. Lichens were primarily selected as indicators. Two different approaches were conducted, direct sampling of Parmotrema reticulatum, at a few places and the use of lichen bags, filled with Usnea sulcata from a northern national park, and hung at different sites. Simultaneously, tree bark was tried as biomonitor. Platanus acerifolia and Melia azedarach were selected as candidates, for being the most common trees in the city, but only P. acerifolia was analyzed. All the samples were analyzed using instrumental neutron activation analysis at the Ezeiza Atomic Centre of the National Atomic Energy Commission. RA-3) reactor was used for the irradiations, determining: As, Ba, Br, Ce, Co, Cr, Cs, Eu, Fe, Hf, K, La, Lu, Na, Rb, Sb, Sc, Sm, Ta, Tb, Th, U, Yb and Zn. Concentration values for P. reticulatum compared well with values from literature. For U. sulcata differences were found among the tested sites and also, for some elements an increasing trend with time was observed. Enrichment factors calculated using Sc as reference and Mason's crustal average concentrations showed vehicules and refuse incineration as contributing sources to the aerosol. Tree bark from Buenos Aires and from a smaller city with mainly agricultural activities were analyzed and the results are coincident with those from lichens. This work is the first and preliminar contribution to the study of Buenos Aires aerosol using biomonitors. (author)

Industrial heritage and tourism: analysis of potentiality and motion for a circuit of industrial tourism in Barracas, Buenos Aires, Argentina

The coast of the Province of Buenos Aires, Argentina, has been studied to determine the wave-power potential. Using wave data (4 yr) from accelerometers, pressure sensors (1 yr) and a visual observation program (10 yr), the wave-power density was calculated at five locations. The annual average increases southwards, ranging between 2.3 kW/m at Mar de Ajo and 7.5 kW/m at Puerto Quequen. Annual averages of maximum wave power give 69 and 61.3 kW/m for Punta Medanos and Puerto Quequen, respectively. (Author).

Price freezes, durables and residential electricity demand - Evidence from the Greater Buenos Aires

Energy Technology Data Exchange (ETDEWEB)

Casarin, Ariel; Delfino, Maria Eugenia

2010-09-15

This paper examines the determinants of residential electricity demand in the Greater Buenos Aires between 1997 and 2006. During the second half of this period, residential tariffs remained nominally fixed, while an income boom boosted up the sales of durables. This study differs from previous works in that it explicitly considers the impact of the stock of air-conditioners on residential demand. The paper reports short- and long-run elasticities and examines the contribution of prices and durables to recent demand growth. Simulations illustrate the impact of prices and durables on future demand.

It seeks to understand the influence of these mechanisms on the local “impure” democracy as alternative and/or complementary channels to the traditional representative way for filing civil claims in instances of political decision making. The methodology combines a literature review, an analysis of documents and the study of the constitutional creation and legislative regulation of these mechanisms, with the count of instances of application and the selection of the most relevant cases. Finally, it performed a comparative study of those cases. In principle the findings highlight the number, variety and high regulation of these mechanisms in Buenos Aires, but then they show the poor empirical results obtained in terms of their contribution to the civic participation and to strengthening democratic. Key words: Crisis of Representation – Citizen participation - Semidirect mechanisms – Political will

Full Text Available In recent decades, rural areas near Bahía Blanca (Buenos Aires, Argentina struggle with many changes as a result of economic and technological transformations. Tese changes have limited rural communities' economic development options, making older development strategies less viable and forcing many to look for nontraditional ways to sustain themselves. One of the most popular strategies has been tourism and recreational activities. The purpose of this article is to establish how public and private initiatives are linked to the local development process. The interviews carried out made it possible to observe a process of transformation in the territory, which involves institutions, organization of actors, and strategies for addressing challenges and opportunities.

Full Text Available Estudiamos la fenología y edad de madurez reproductiva y el tamaño y la frecuencia de la puesta de una población de Liolaemus gracilis de las dunas costeras de Buenos Aires, Argentina. Examinamos las gónadas de 93 ejemplares coleccionados mensualmente a lo largo de un año en la localidad de Mar del Sur (provincia de Buenos Aires y medimos 11 caracteres morfométricos en 39 adultos en búsqueda de dimorfismo sexual. Las hembras se consideraron maduras si poseían folículos yemados mayores a 2 mm, o huevos oviductales, u oviductos claramente distendidos. En los machos los indicadores de madurez sexual fueron la presencia de testículos agrandados y el estado convoluto de los epidídimos, midiéndose el ancho y largo del testículo izquierdo en cada uno. L. gracilis exhibió un patrón reproductivo estacional con características del tipo parcial de otoño. El tamaño medio de las hembras en actividad reproductiva fue de 48,9 mm ± 3,5 (largo hocico-cloaca (n = 19 y la menor madura sexualmente midió 43,8 mm. El tamaño de la puesta varió de 4 a 6 huevos ( X = 4,75 ± 0,95, n = 4. El macho de menor tamaño con testículos agrandados midió 40,5 mm. (largo hocico-cloaca.

El concurso para la ampliación del cementerio de San Michele, convocado en 1998 por la administración Municipal de Venecia, se convierte en un excelente campo de pruebas sobre el que poder analizar el contexto histórico en torno a esta tipología, y su relación con la ciudad y el territorio. El estudio de este caso concreto nos permite descubrir personajes, relaciones casuales y hallazgos que se despliegan a lo largo del texto. La historia del cementerio de San Michele es también la crónica de la transformación de la ciudad de Venecia y su Laguna. Interpretando este concurso como un instrumento de investigación, el objetivo del artículo es el de comprender la realidad contemporánea de la arquitectura funeraria a través de la isla de San Michele, Venecia, y las propuestas finalistas de Carlos Ferrater, Enric Miralles y David Chipperfield. Una historia bajo la cual se vislumbran claves que nos sirven para reflexionar acerca del cementerio contemporáneo, la ciudad y el territorio.

Los eventos frecuentes de temperaturas extremas frías en la segunda quincena de octubre, coincidentes con un momento fenológico sensible del trigo, provocan daños de importancia en el cultivo. El presente trabajo tiene como objetivo proveer mapas de riesgo de temperaturas extremas frías para el período sensible del cultivo de trigo en esa región. Se utilizó información de los canales 3, 4 y 5 del satélite NOAA de 1,09 km² de resolución espacial, obtenidas en el Instituto de Clima y Agua del INTA-Castelar entre 2005 y 2008, y datos diarios de temperaturas mínimas del período 1961-2008 de 13 estaciones de superficie del Servicio Meteorológico Nacional (SMN y del Instituto Nacional de Tecnología Agropecuaria (INTA. Los resultados muestran que las áreas de mayor riesgo son aquellas que combinan menor altura sobre el nivel del mar y al mismo tiempo mayor distancia al mismo. Esta metodología puede ser extendida a otros cultivos y a otras regiones.

We examine the Pleistocene tectonic reorganization of the Pacific-North American plate boundary in the Salton Trough of southern California with an integrated approach that includes basin analysis, magnetostratigraphy, and geologic mapping of upper Pliocene to Pleistocene sedimentary rocks in the San Felipe Hills. These deposits preserve the earliest sedimentary record of movement on the San Felipe and San Jacinto fault zones that replaced and deactivated the late Cenozoic West Salton detachment fault. Sandstone and mudstone of the Brawley Formation accumulated between ???1.1 and ???0.6-0.5 Ma in a delta on the margin of an arid Pleistocene lake, which received sediment from alluvial fans of the Ocotillo Formation to the west-southwest. Our analysis indicates that the Ocotillo and Brawley formations prograded abruptly to the east-northeast across a former mud-dominated perennial lake (Borrego Formation) at ???1.1 Ma in response to initiation of the dextral-oblique San Felipe fault zone. The ???25-km-long San Felipe anticline initiated at about the same time and produced an intrabasinal basement-cored high within the San Felipe-Borrego basin that is recorded by progressive unconformities on its north and south limbs. A disconformity at the base of the Brawley Formation in the eastern San Felipe Hills probably records initiation and early blind slip at the southeast tip of the Clark strand of the San Jacinto fault zone. Our data are consistent with abrupt and nearly synchronous inception of the San Jacinto and San Felipe fault zones southwest of the southern San Andreas fault in the early Pleistocene during a pronounced southwestward broadening of the San Andreas fault zone. The current contractional geometry of the San Jacinto fault zone developed after ???0.5-0.6 Ma during a second, less significant change in structural style. ?? 2007 by The University of Chicago.

Mycobacterioses can produce nonspecific clinical signs in dogs and cats that make diagnosis difficult. Furthermore, the full characterization of mycobacterial agents is not always possible or practical. We characterized mycobacteria detected through cytology in 12 dogs and 7 cats with generalized clinical signs from the province of Buenos Aires in Argentina. In dogs, molecular testing confirmed the presence of Mycobacterium avium subsp. hominissuis (MAH) in 8 cases and M. fortuitum in 1 case. All dogs were Miniature Schnauzers, suggesting that this breed may be more susceptible to M. avium than other dog breeds. The cat isolates were 2 M. bovis, 1 M. fortuitum, and 1 MAH. Mycobacterial interspersed repetitive unit-variable-number tandem repeat patterns suggested possible links with cattle, swine, and humans studied previously in Argentina. The results show that pets may act as susceptible hosts with the potential risk of transmitting the infection to humans and other animals.

Full Text Available The number of publications in the scientific literature coming from an institution is an indicator of its scientific production. The scientific production of the hospitals of the Government of the City of Buenos Aires (GCBA has been evaluated previously, but without discriminating how much of that production corresponded to other academic institutions settled there (University of Buenos Aires, UBA, National Council of Scientific Research and Techniques, CONICET. Our objective was to evaluate the publications included in PubMed that correspond to hospitals of the GCBA, describe their main characteristics, and discriminate the contribution of other academic institutions (UBA and CONICET. It is a cross-sectional study based on a PubMed search, using the name of each of the 34 GCBA hospitals, CONICET and UBA in the "affiliation" field. In total, 2727 publications from GCBA hospitals were identified (4.6% of Argentine publications; 73.9% in English, 78.9% in relation to humans, 37.2% in the last 5 years; 6.4% with high level of evidence (clinical trials and meta-analysis, and 28.4% including children. Compared to the national total, the GCBA publications include fewer works in English, more research in humans, more clinical trials and more research in children. Of the publications corresponding to hospitals of the GCBA, 90.4% did not share the affiliation with CONICET or with UBA. In conclusion, the GCBA hospitals generated 4.6% of the total Argentine publications in PubMed; and 90% of these was not shared with UBA or CONICET. Publications from GCBA institutions include more clinical trials and research in children.

Full Text Available ABSTRACT The mainland population of the ruddy-headed goose (Chloephaga rubidiceps breeds in southern Patagonia and winters in the south of Buenos Aires province (Argentina, with a recent estimated size at around 900 individuals. This population is considered "in danger of extinction", while the Malvinas (Falkland Islands population is in well conservation status, with an estimated size of 40,000 birds. The aim of this work is to contribute with updated information about the ruddy-headed goose's population wintering in southern Buenos Aires province. The specific objectives were to better delimit its wintering area, to look for sites with large numbers, to study its habitat used, and to identify main threats to the species. Two intensive surveys were conducted during the austral winter of 1999. The results: (1 confirm the low abundance of the ruddy-headed goose supporting its critical conservation status, (2 corroborate its very restricted distribution, with more than 80 % of sightings concentrated in an area of 13,000 ha in southern Buenos Aires province, and (3 suggest that changes in the species' habitat use during the wintering season appear to be a response to changes in habitat availability, resulting from the growth of crops and pastures. The overlap between the species wintering distribution and the main wheat cropping areas of Argentina results in serious threats to this goose. Management actions are discussed to contribute to the conservation of this endangered species.La población continental del Cauquén colorado (Chloephaga rubidiceps cría en el sur de la Patagonia e inverna en el sur de la provincia de Buenos Aires (Argentina, con un tamaño poblacional estimado recientemente en alrededor de 900 individuos.

Full Text Available Argentina constituye el segundo mercado eléctrico de América del Sur (100.000 GWh consumidos en 2008, según cifras de la Agencia Internacional de la Energía 2010, después de Brasil. La mayor parte del consumo se concentra en la región metropolitana de Buenos Aires cuyos hogares absorben 40% de la electricidad destinada a fines domésticos y las industrias toman 60% del total. Los altos niveles de demanda de la metrópolis han justificado históricamente inversiones en proyectos energéticos, algunos locales, otros en sitios alejados. Así Buenos Aires genera e importa electricidad para cubrir sus necesidades mientras se observa que las regiones exportadoras a veces carecen de servicios locales suficientes. En la región del Noreste, donde se localiza la mayor represa del país –la represa binacional de Yacyretá- la tasa de cobertura eléctrica es inferior a la media nacional (siendo ellas de 90% y 95% respectivamente. Existen luego desigualdades en disponibilidad de electricidad a nivel nacional. Esta presentación1 busca mostrar en qué forma Buenos Aires se ha abastecido de electricidad y las implicancias que el desarrollo de ese mercado trae para las regiones exportadoras. En particular se estudia el sistema de producción y distribución de una de las mayores centrales hidroeléctricas y se constatan las dificultades y beneficios que ha encontrado la región del Noreste, en la obra de Yacyretá, ya en términos de abastecimiento, ya en términos socioeconómicos.

Full Text Available Objective: To show the toxicological and phylogenetic characterization of a native Microcystis aeruginosa (M. aeruginosa strain (named CAAT 2005-3 isolated from a water body of Buenos Aires province, Argentine. Methods: A M. aeruginosa strain was isolated from the drainage canal of the sewage treatment in the town of Pila, Buenos Aires province, Argentina and acclimated to laboratory conditions. The amplification of cpcBA-IGS Phcocyanin (PC, intergenic spacer and flanking regions was carried out in order to build a phylogenetic tree. An exactive/orbitrap mass spectrometer equipped with an electrospray ionization source (Thermo Fisher Scientific, Bremen, Germany was used for the LC/ESI-HRMS microcystins analysis. The number of cell/mL and [D-Leu1] Mcyst-LR production obtained as a function of time was modelled using the Gompertz equation. Results: The phylogenetic analysis showed that the sequence clustered with others M. aeruginosa sequences obtained from NCBI. The first Argentinian strain of M. aeruginosa (CAAT 2005-3 growing under culture conditions maintains the typical colonial architecture of M. aeruginosa with profuse mucilage. M. aeruginosa CAAT 2005-3 expresses a toxin variant, that was identified by LC-HRMS/Orbitrapas as [D-Leu1] microcystin-LR ([M+H]+=1 037.8 m/z. Conclusions: [D-Leu1] microcystin-LR has been also detected in M. aeruginosa samples from Canada, Brazil and Argentina. This work provides the basis for technological development and production of analytical standards of toxins present in our region.

This signal was found out in many of the sampled wells and allowed to recognize the recharge, even to significant depths. In the Pinamar and Villa Gesell towns, it was possible to establish the dynamic of wells under seasonal exploitation. In the most of cases water withdrawn in summer was recharged in the immediate precedent pluvious period. Refs, figs and tabs.

Cataclastic rocks of the San Gabriel fault—an expression of deformation at deeper crustal levels in the San Andreas fault zone

The San Gabriel fault, a deeply eroded late Oligocene to middle Pliocene precursor to the San Andreas, was chosen for petrologic study to provide information regarding intrafault material representative of deeper crustal levels. Cataclastic rocks exposed along the present trace of the San Andreas in this area are exclusively a variety of fault gouge that is essentially a rock flour with a quartz, feldspar, biotite, chlorite, amphibole, epidote, and Fe-Ti oxide mineralogy representing the milled-down equivalent of the original rock (Anderson and Osborne, 1979; Anderson et al., 1980). Likewise, fault gouge and associated breccia are common along the San Gabriel fault, but only where the zone of cataclasis is several tens of meters wide. At several localities, the zone is extremely narrow (several centimeters), and the cataclastic rock type is cataclasite, a dark, aphanitic, and highly comminuted and indurated rock. The cataclastic rocks along the San Gabriel fault exhibit more comminution than that observed for gouge along the San Andreas. The average grain diameter for the San Andreas gouge ranges from 0.01 to 0.06 mm. For the San Gabriel cataclastic rocks, it ranges from 0.0001 to 0.007 mm. Whereas the San Andreas gouge remains particulate to the smallest grain-size, the ultra-fine grain matrix of the San Gabriel cataclasite is composed of a mosaic of equidimensional, interlocking grains. The cataclastic rocks along the San Gabriel fault also show more mineralogiec changes compared to gouge from the San Andreas fault. At the expense of biotite, amphibole, and feldspar, there is some growth of new albite, chlorite, sericite, laumontite, analcime, mordenite (?), and calcite. The highest grade of metamorphism is laumontite-chlorite zone (zeolite facies). Mineral assemblages and constrained uplift rates allow temperature and depth estimates of 200 ± 30° C and 2-5 km, thus suggesting an approximate geothermal gradient of ~50°C/km. Such elevated temperatures imply a

Estudios previos en Buenos Aires reportaron altas prevalencias de HIV entre HSH, con valores que oscilan entre 9 y 14% durante casi 10 años de continuo testeo. El objetivo principal de este estudio fue la evaluación de factores relacionados al comportamiento de alto riesgo para transmisión del HIV entre HSH entre los que se incluyen el conocimiento y factores emocionales, socioculturales y ambientales. Por otro lado se realizó la estimación de prevalencia e incidencia de HIV utilizando RDS (Respondent Driven Sampling), así como la presencia de otras infecciones de transmisión sexual. Por último se evaluaron los hábitos de testeo para HIV indagando que factores facilitan o impiden su realización. El estudio constó de dos fases, en primer lugar una fase cualitativa y posteriormente una fase cuantitativa con una duración total de 4 años y medio. Durante la fase cualitativa se realizaron 44 entrevistas individuales en profundidad, 8 grupos focales y 10 observaciones etnográficas (hoteles, baños públicos ("teteras"), cines pornográficos, fiestas privadas, dark rooms y discotecas). Durante la fase cuantitativa del estudio se realizó el reclutamiento de 500 participantes que provinieron de la Ciudad Autónoma de Buenos Aires, así como del Gran Buenos Aires. El reclutamiento se comenzó con 16 participantes llamados semillas. Se realizó el diagnóstico de infección por HIV, hepatitis B y C (HBV y HCV), Treponema pallidum, Virus Papiloma Humano (HPV) y Chlamidias. La colaboración establecida entre los grupos de trabajo enfocados en áreas diversas posibilitó el abordaje conjunto de nuevas estrategias de investigación antes no exploradas en nuestro país. Los resultados más relevantes de esta investigación serán progresivamente publicados en sucesivos números de Actualizaciones en SIDA.

Southern Africa was likely exclusively inhabited by San hunter-gatherers before ~2000 years ago. Around that time, East African groups assimilated with local San groups and gave rise to the Khoekhoe herders. Subsequently, Bantu-speaking farmers, arriving from the north (~1800 years ago), assimilated and displaced San and Khoekhoe groups, a process that intensified with the arrival of European colonists ~350 years ago. In contrast to the western parts of southern Africa, where several Khoe-San groups still live today, the eastern parts are largely populated by Bantu speakers and individuals of non-African descent. Only a few scattered groups with oral traditions of Khoe-San ancestry remain. Advances in genetic research open up new ways to understand the population history of southeastern Africa. We investigate the genomic variation of the remaining individuals from two South African groups with oral histories connecting them to eastern San groups, i.e., the San from Lake Chrissie and the Duma San of the uKhahlamba-Drakensberg. Using ~2.2 million genetic markers, combined with comparative published data sets, we show that the Lake Chrissie San have genetic ancestry from both Khoe-San (likely the ||Xegwi San) and Bantu speakers. Specifically, we found that the Lake Chrissie San are closely related to the current southern San groups (i.e., the Karretjie people). Duma San individuals, on the other hand, were genetically similar to southeastern Bantu speakers from South Africa. This study illustrates how genetic tools can be used to assess hypotheses about the ancestry of people who seemingly lost their historic roots, only recalling a vague oral tradition of their origin.

Viral diagnostic criteria for Feline immunodeficiency virus and Feline leukemia virus infections in domestic cats from Buenos Aires, Argentina.

Science.gov (United States)

Galdo Novo, Sabrina; Bucafusco, Danilo; Diaz, Leandro M; Bratanich, Ana Cristina

A cross-sectional study was carried out on cats attending the Small Animal Hospital at the Faculty of Veterinary Sciences of the University of Buenos Aires to assess the prevalence and associated risk factors of Feline immunodeficiency virus (FIV) and Feline leukemia virus (FeLV) in the city of Buenos Aires, Argentina. Blood samples from 255 cats with symptoms compatible with FIV or FeLV infection, collected between 2009 and 2013 were analyzed by serology (immunochromatography, IA) and by hemi-nested PCR (n-PCR). The IA and n-PCR assays showed similar percentages of positivity for FIV while the n-PCR test was more sensitive for FeLV. Differences between the diagnostic tests and their choice according to the age of the animal are discussed. The clinical histories of ninety of the 255 cats showed blood profiles similar to others previously reported and revealed a higher risk of infection in male adult cats with outdoor access.

The analysis of current regulations in each of the 23 counties comprised in the study will allow us to define future intervention strategies, which will act as instruments in connection with land regulation for each municipality's management.

Toxic phytoplankton in San Francisco Bay

Science.gov (United States)

Rodgers, Kristine M.; Garrison, David L.; Cloern, James E.

1996-01-01

The Regional Monitoring Program (RMP) was conceived and designed to document the changing distribution and effects of trace substances in San Francisco Bay, with focus on toxic contaminants that have become enriched by human inputs. However, coastal ecosystems like San Francisco Bay also have potential sources of naturally-produced toxic substances that can disrupt food webs and, under extreme circumstances, become threats to public health. The most prevalent source of natural toxins is from blooms of algal species that can synthesize metabolites that are toxic to invertebrates or vertebrates. Although San Francisco Bay is nutrient-rich, it has so far apparently been immune from the epidemic of harmful algal blooms in the world’s nutrient-enriched coastal waters. This absence of acute harmful blooms does not imply that San Francisco Bay has unique features that preclude toxic blooms. No sampling program has been implemented to document the occurrence of toxin-producing algae in San Francisco Bay, so it is difficult to judge the likelihood of such events in the future. This issue is directly relevant to the goals of RMP because harmful species of phytoplankton have the potential to disrupt ecosystem processes that support animal populations, cause severe illness or death in humans, and confound the outcomes of toxicity bioassays such as those included in the RMP. Our purpose here is to utilize existing data on the phytoplankton community of San Francisco Bay to provide a provisional statement about the occurrence, distribution, and potential threats of harmful algae in this Estuary.

ASTER Flyby of San Francisco

2002-01-01

The Advanced Spaceborne Thermal Emission and Reflection radiometer, ASTER, is an international project: the instrument was supplied by Japan's Ministry of International Trade and Industry. A joint US/Japan science team developed algorithms for science data products, and is validating instrument performance. With its 14 spectral bands, extremely high spatial resolution, and 15 meter along-track stereo capability, ASTER is the zoom lens of the Terra satellite. The primary mission goals are to characterize the Earth's surface; and to monitor dynamic events and processes that influence habitability at human scales. ASTER's monitoring and mapping capabilities are illustrated by this series of images of the San Francisco area. The visible and near infrared image reveals suspended sediment in the bays, vegetation health, and details of the urban environment. Flying over San Francisco (3.2MB) (high-res (18.3MB)), we see the downtown, and shadows of the large buildings. Past the Golden Gate Bridge and Alcatraz Island, we cross San Pablo Bay and enter Suisun Bay. Turning south, we fly over the Berkeley and Oakland Hills. Large salt evaporation ponds come into view at the south end of San Francisco Bay. We turn northward, and approach San Francisco Airport. Rather than landing and ending our flight, we see this is as only the beginning of a 6 year mission to better understand the habitability of the world on which we live.

Claudia Irene Menghi

Full Text Available Hydatidosis is a parasitic infection caused by the tapeworm larva of Echinococcus spp. Its relevance lies in its wide distribution, great number of clinical cases and outstanding morbility. Hydatid infection of the orbit comprises far less than 1% of the total incidence. This is a case of a patient from Argentina complaining of a two-week evolution proptosis of the right eye. A microscopic examination revealed the presence of protoscolices of Echinococcus spp. in the fluid obtained during the surgical proceedings. The patient was treated with oral albendazole. To our knowledge, this is the first case of occular hydatidosis diagnosed in the city of Buenos Aires, Argentina.

SANS studies of polymers

International Nuclear Information System (INIS)

Wignall, G.D.

1984-10-01

Before small-angle neutron scattering (SANS), chain conformation studies were limited to light and small angle x-ray scattering techniques, usually in dilute solution. SANS from blends of normal and labeled molecules could give direct information on chain conformation in bulk polymers. Water-soluble polymers may be examined in H 2 O/D 2 O mixtures using contrast variation methods to provide further information on polymer structure. This paper reviews some of the information provided by this technique using examples of experiments performed at the National Center for Small-Angle Scattering Research (NCSASR)

Modeling pesticide loadings from the San Joaquin watershed into the Sacramento-San Joaquin Delta using SWAT

Science.gov (United States)

Chen, H.; Zhang, M.

2016-12-01

The Sacramento-San Joaquin Delta is an ecologically rich, hydrologically complex area that serves as the hub of California's water supply. However, pesticides have been routinely detected in the Delta waterways, with concentrations exceeding the benchmark for the protection of aquatic life. Pesticide loadings into the Delta are partially attributed to the San Joaquin watershed, a highly productive agricultural watershed located upstream. Therefore, this study aims to simulate pesticide loadings to the Delta by applying the Soil and Water Assessment Tool (SWAT) model to the San Joaquin watershed, under the support of the USDA-ARS Delta Area-Wide Pest Management Program. Pesticide use patterns in the San Joaquin watershed were characterized by combining the California Pesticide Use Reporting (PUR) database and GIS analysis. Sensitivity/uncertainty analyses and multi-site calibration were performed in the simulation of stream flow, sediment, and pesticide loads along the San Joaquin River. Model performance was evaluated using a combination of graphic and quantitative measures. Preliminary results indicated that stream flow was satisfactorily simulated along the San Joaquin River and the major eastern tributaries, whereas stream flow was less accurately simulated in the western tributaries, which are ephemeral small streams that peak during winter storm events and are mainly fed by irrigation return flow during the growing season. The most sensitive parameters to stream flow were CN2, SOL_AWC, HRU_SLP, SLSUBBSN, SLSOIL, GWQMN and GW_REVAP. Regionalization of parameters is important as the sensitivity of parameters vary significantly spatially. In terms of evaluation metric, NSE tended to overrate model performance when compared to PBIAS. Anticipated results will include (1) pesticide use pattern analysis, (2) calibration and validation of stream flow, sediment, and pesticide loads, and (3) characterization of spatial patterns and temporal trends of pesticide yield.

Full Text Available The aim of this paper is to quantify one of the characteristics of the production function of the tourism sector in the province of Buenos Aires: the dominant factor content of their touristic resources, one simplified concept which shows the factors of production incorporated in goods. For its estimation and the touristic characterization of the different municipalities of the province, the following elements are used: the inventory of touristic resources of 134 municipalities of the province; their classification into the five categories listed by OEA; and the factor intensity of each category. One interesting result is that most municipalities with high touristic GDP show a dominant factor content of capital, the implication being that comparative advantage in the Province of Buenos Aires in Argentina is based on contemporary technical, scientific and artistic work. It may be concluded that there is place to exploit tourism in Argentina, what points to the need to accompany them with a correct design of public policies.

Money, morality, and politics in the slums of Buenos Aires

Ariel Wilkis

2016-06-01

Full Text Available Abstract Studies on the political life of the poor in Latin American have rarely focused on money, although there have been works focused on the survival strategies of the poor; political clientelism; and collective mobilizations. In this article, I analyze political life in the poor neighborhoods of Greater Buenos Aires through the lens of money that circulates within the Peronist networks. I conducted ethnography fieldwork between 2006 and 2010. Does money have a legitimate role in politics? Has the monetization of political activities dissolved values, commitments, and loyalties among the poor? Is this corruption, or is this an ethical exchange among people who lack cash but possess moral capital? Here, I analyze how money becomes necessary to strengthen commitments, loyalties, obligations, expectations, and plans for both leaders and activists. Reconstructing this process can provide a foundation for the revision of place of money in political life.

Full Text Available The aim of this study is to elucidate butterfly fauna in Mt. Gariwang-san, Korea. A field survey was conducted from 2010 to 2015 using the line transect method. A literature survey was also conducted. A total of 2,037 butterflies belonging to 105 species were recorded. In the estimation of species richness of butterfly, 116 species were estimated to live in Mt. Gariwang-san. In butterfly fauna in Mt. Gariwang-san, the percentage of northern species was very high and the percentage of grassland species was relatively higher than that of forest edge species and forest interior species. Sixteen red list species were found. In particular, Mimathyma nycteis was only recorded in Mt. Gariwang-san. When comparing the percentage of northern species and southern species including those recorded in previous studies, the percentage of northern species was found to have decreased significantly whereas that of southern species increased. We suggest that the butterfly community, which is distributed at relatively high altitudes on Mt. Gariwang-san, will gradually change in response to climate change.

Milicias y tropas negras de Buenos Aires. Afro argentinos armados para defender a sus amos

Full Text Available The city of Buenos Aires was founded, for the second time 1580 essentially as an outpost of the Spanish Empire to be protected from Indian attacks and possible foreign incursion, basically Portuguese in origin. Thus, from the beginnings of the city's founding, African slaves were used for the defense of the city. They acted in the urban militias, and were outstanding in the defense and re-conquest of the city when the English attacked in 1806- 1807. Innumerable prizes and eulogies were followed by integration of segregated divisions with a white officer corps.After 1813, a series of decrees ordered owners to exchange slaves for use in the Wars of Independence. Thus, property owners were obliged to sell to the State a number of their slaves according to the work performed by the slaves. The slaves would enter the armies as free persons and would serve five years as 'front line" soldiers in order to obtain their freedom. This article studies the participation of the Afro-Argentines in the distinct 'fronts" of the armies of liberation. The paper also reflects on the opinions of the generals who commanded Afro-Argentine troops.//La ciudad de Buenos Aires fue fundada, por segunda vez, en 1580 esencialmente como un puesto de avanzada para que los españoles se protegieran de los indígenas y de una posible incursión extranjera de origen portugués.

Distribution and demography of San Francisco gartersnakes (Thamnophis sirtalis tetrataenia) at Mindego Ranch, Russian Ridge Open Space Preserve, San Mateo County, California

San Francisco gartersnakes (Thamnophis sirtalis tetrataenia) are a subspecies of common gartersnakes endemic to the San Francisco Peninsula of northern California. Because of habitat loss and collection for the pet trade, San Francisco gartersnakes were listed as endangered under the precursor to the Federal Endangered Species Act. A population of San Francisco gartersnakes resides at Mindego Ranch, San Mateo County, which is part of the Russian Ridge Open Space Preserve owned and managed by the Midpeninsula Regional Open Space District (MROSD). Because the site contained non-native fishes and American bullfrogs (Lithobates catesbeianus), MROSD implemented management to eliminate or reduce the abundance of these non-native species in 2014. We monitored the population using capture-mark-recapture techniques to document changes in the population during and following management actions. Although drought confounded some aspects of inference about the effects of management, prey and San Francisco gartersnake populations generally increased following draining of Aquatic Feature 3. Continued management of the site to keep invasive aquatic predators from recolonizing or increasing in abundance, as well as vegetation management that promotes heterogeneous grassland/shrubland near wetlands, likely would benefit this population of San Francisco gartersnakes.

Resumen Estudios previos en Buenos Aires reportaron altas prevalencias de HIV entre HSH, con valores que oscilan entre 9 y 14% durante casi 10 años de continuo testeo. El objetivo principal de este estudio fue la evaluación de factores relacionados al comportamiento de alto riesgo para transmisión del HIV entre HSH entre los que se incluyen el conocimiento y factores emocionales, socioculturales y ambientales. Por otro lado se realizó la estimación de prevalencia e incidencia de HIV utilizando RDS (Respondent Driven Sampling), así como la presencia de otras infecciones de transmisión sexual. Por último se evaluaron los hábitos de testeo para HIV indagando que factores facilitan o impiden su realización. El estudio constó de dos fases, en primer lugar una fase cualitativa y posteriormente una fase cuantitativa con una duración total de 4 años y medio. Durante la fase cualitativa se realizaron 44 entrevistas individuales en profundidad, 8 grupos focales y 10 observaciones etnográficas (hoteles, baños públicos (“teteras”), cines pornográficos, fiestas privadas, dark rooms y discotecas). Durante la fase cuantitativa del estudio se realizó el reclutamiento de 500 participantes que provinieron de la Ciudad Autónoma de Buenos Aires, así como del Gran Buenos Aires. El reclutamiento se comenzó con 16 participantes llamados semillas. Se realizó el diagnóstico de infección por HIV, hepatitis B y C (HBV y HCV), Treponema pallidum, Virus Papiloma Humano (HPV) y Chlamidias. La colaboración establecida entre los grupos de trabajo enfocados en áreas diversas posibilitó el abordaje conjunto de nuevas estrategias de investigación antes no exploradas en nuestro país. Los resultados más relevantes de esta investigación serán progresivamente publicados en sucesivos números de Actualizaciones en SIDA. PMID:25264397

Alameda County is located at the northern end of the Diablo Range of Central California. It is bounded on the north by the south flank of Mount Diablo, one of the highest peaks in the Bay Area, reaching an elevation of 1173 meters (3,849 ft). San Francisco Bay forms the western boundary, the San Joaquin Valley borders it on the east and an arbitrary line from the Bay into the Diablo Range forms the southern boundary. Alameda is one of the nine Bay Area counties tributary to San Francisco Bay. Most of the country is mountainous with steep rugged topography. Alameda County is covered by twenty-eight 7.5' topographic Quadrangles which are shown on the index map. The Quaternary deposits in Alameda County comprise three distinct depositional environments. One, forming a transgressive sequence of alluvial fan and fan-delta facies, is mapped in the western one-third of the county. The second, forming only alluvial fan facies, is mapped in the Livermore Valley and San Joaquin Valley in the eastern part of the county. The third, forming a combination of Eolian dune and estuarine facies, is restricted to the Alameda Island area in the northwestern corner of the county.

Development of 40m SANS and Its Utilization Techniques

International Nuclear Information System (INIS)

Choi, Sung Min; Kim, Tae Hwan

2010-06-01

Small angle neutron scattering (SANS) has been a very powerful tool to study nanoscale (1-100 nm) bulk structures in various materials such as polymer, self assembled materials, nano-porous materials, nano-magnetic materials, metal and ceramics. Understanding the importance of the SANS instrument, the 8m SANS instrument was installed at the CN beam port of HANARO in 2001. However, without having a cold neutron source, the beam intensity is fairly low and the Q-range is rather limited due to short instrument length. In July 1, 2003, therefore, the HANARO cold neutron research facility project was launched and a state of the art 40m SANS instrument was selected as top-priority instrument. The development of the 40m SANS instrument was completed as a joint project between Korea Advanced Institute of Science and Technology and the HANARO in 2010. Here, we report the specification of a state of art 40m SANS instrument at HANARO

A Mining Feasibility Study in the Area of Alto San Jorge, Department of Cordoba, Colombia, was commissioned by CARBOCOL S.A. to the Consortium Geominas-NACI. An area of 800 Ka2 was explored to define surface mining possibilities within two subareas referred to as Alto San Jorge and San Pedro Ure. Rocks of Cretaceous, Tertiary and Quaternary age crop out in the zone. In the subarea Alto San Jorge the principal structure is a syncline with a south-north direction. The San Pedro Ure subarea is formed by undulations with flanks of low dip, the most important being the San Antonio Syncline because it contains the mining block. The geological study of the surface demonstrated the existence of coal in the Oligocene Cienaga de Oro Formation and the Niocene Cerrito Formation, with potential resources of 6.3 billion tons. The subsequent exploration of the subsoil, with 20.618 m of drilling, permitted determination of demonstrated reserves in the order of 2.9 billion tons within two areas. In the sector selected for the mine plan, in the area of San Pedro-Puerto Libertador, 7.791 m of drilling was accomplished to define a demonstrated reserve of 515 million tons of coal down to a depth of 200. The combustible type coal has 5.000 cal/g. Complete mining schedules were developed at the prefeasibility level for two surface mines with productions of 1.5 MMTY and 4 MMTY. 9 figs., 3 tabs., 28 refs.

Full Text Available The following paper analyses the behaviour of three of the most important monastic communities in the reing of Asturias-Leon for the ninth and then centuries. During this period we witness the implementation of a new ordo, or liturgical ritual that replaces the Hispanic one, strongly established in the Territorium. The liturgical adaptation produces tension and conflicts among the members of different monastic communities, and even between the Episcopate and the monarchy - being King Alfonso VI. In some of the monasteries, the arrival of the new ordo causes the adaptation of the liturgical space, with subsequent changes in liturgical furniture.

Full Text Available This paper seeks to examine the global organization of two Spanish American colonial spaces during the era of free trade: the Hispanic North and Rio de la Plata. By studying the consular records on foreign trade, included in the derecho de avería records, I analyse how their economies were integrated into the circulation of silver, slaves, and imports. Moreover, I explain the institutional development of their trade communities, favored by the body of consulates in the cities of Guadalajara and Buenos Aires, viewed as institutional instruments of corporate negotiation, market administration, and interest organization against a backdrop of trade globalization.

Full Text Available La Ciudad de Buenos Aires está emplazada sobre el margen sur del estuario del Río de la Plata. Las obras de relleno modificaron totalmente la morfología original del área, desde la época de Rosas (1836 hasta la actualidad. Los cambios antrópicos en la configuración de la línea de costa generaron una gran variedad de problemas de fundación en las estructuras edilicias y obras de infraestructura a causa de la heterogeneidad de la composición de los materiales utilizados para el relleno. Debido al creciente desarrollo urbano de la Ciudad Autónoma de Buenos Aires y el área metropolitana, resulta de sumo interés contar con información de detalle sobre las áreas de relleno en la costa del Río de la Plata. Con la finalidad de evaluar la utilidad de diferentes métodos geofísicos para caracterizar el tipo y distribución espacial de los materiales de relleno y su espesor, en este trabajo se presentan los resultados de un estudio piloto llevado a cabo en Ciudad Universitaria. Se realizaron relevamientos con Georadar (GPR, tomografías de resistividad eléctrica (TER y perfiles magnetométricos. Pudo determinarse que las TERs y los métodos magnéticos son muy útiles para investigar las zonas de relleno, mientras que el método de GPR no sería aplicable a la zona de estudio debido a las características intrínsecas de la misma. A partir de los relevamientos realizados pudieron diferenciarse sectores geográficamente muy cercanos dentro de Ciudad Universitaria que presentarían distintos espesores y tipo de relleno. Estos resultados indican que los métodos geofísicos permitirían caracterizar las zonas de relleno a lo largo de la costa de Buenos Aires y nos alientan a continuar esta línea de trabajo.The coast of Buenos Aires city is located on the southern margin of La Plata river estuary.

Buenos Aires city and its surroundings, has a huge population and very dense traffic. There are many possible pollution sources that can be identified, but other characteristics such as weather and location counteract some of these sources to the benefit of the atmosphere of the city. Although several groups have been working on these subjects, there is not enough information about which elements are present in Buenos Aires air. The aim of this project is to provide information about the elemental profile of the atmosphere of the city and to evaluate and to make an interpretation of the obtained data. Both XRF and INAA are going to be used for analyzing the air filter samples with the participation of the Meteorological Service in sampling and interpretation of the results. By choosing adequate sampling sites and times, differences between day/night, week day/weekend will be looked for. The influence of non-leaded petrols will be studied. Some work on air samples was done before the beginning of this contract to settle future working conditions. Some results from this study are presented only as preliminary ones. Sampling will begin during this April at two sites with different traffic density. For both XRF and NAA suitable standards will be prepared. Medium and long lived nuclides are going to be analyzed by INAA. Plans for 1993 are given as well as possible collaboration with other groups in the country. (author). 3 refs, 1 tab

Full Text Available O uso de imagens SAR para estimar e monitorar a umidade superficial do solo requer que se considere outros fatores que influenciam na retrodifusão do sinal-radar, entre os quais a rugosidade da cobertura da superfície à escala de centímetro é muito importante. Há diversos métodos para determinar a rugosidade, mas muitos são caros ou de operação de campo complexa. Neste trabalho, é apresentado um método versátil e econômico que usa máquina fotográfica e tela quadrada. Cada fotografia é processada numericamente obtendo a altura RMS, como parâmetro da rugosidade da cobertura. Por meio de técnicas geoestatísticas de krigagem é estimada a distribuição espacial da rugosidade. São mostradas experiências em áreas com cobertura de trigo, localizadas na área agrícola serrana da Província o Buenos Aires, Argentina. Os valores de RMS encontrados (29 mm Use of SAR images for soil surface moisture estimation requires taking into account the other factors that influence the radar backscattering signal, among which the surface cover roughness at centimeter scale is very important. There are several methods to determine the roughness, but many are expensive or complex field operation. A versatile and economic method that uses a photographic camera and a girded screen is presented. Each picture is numerically processed obtaining the RMS height, as parameter of the crop-soil complex roughness. By means of krigging geostatistics techniques the spatial distribution of roughness is estimated. Experiences in parcels with wheat cover, located in the hill agricultural area of Buenos Aires Province, Argentina are shown. The found RMS values (29 mm < RMS < 48 mm are analyzed with four roughness approaches. Their utility in order to estimate soil surface moisture status in agricultural parcels by means of their application like input into the SAR images backscattering models is stated.

John Tweedie and Charles Darwin in Buenos Aires.

Ollerton, Jeff; Chancellor, Gordon; van Wyhe, John

2012-06-20

The journey of exploration undertaken by Charles Darwin FRS during the voyage of HMS Beagle has a central place within the historical development of evolutionary theory and has been intensively studied. Despite this, new facts continue to emerge about some of the details of Darwin's activities. Drawing on recently published Darwin material and unpublished letters in the archives of the Royal Botanic Gardens, Kew, we document a hitherto unexamined link between Darwin and John Tweedie (1775-1862), a relatively obscure Scottish gardener turned South American plant collector. All of the available evidence points to a meeting between the two men in Buenos Aires in 1832. Tweedie provided Darwin with information about the geography of the Rio Paraná, including the locality of fossilized wood eroding from the river bank. It also seems likely that Tweedie supplied Darwin with seeds that he later shipped back to John Stevens Henslow in Cambridge. Although this brief meeting was at the time relatively unimportant to either man, echoes of that encounter have resonated with Tweedie's descendants to the present day and have formed the basis for a family story about a written correspondence between Darwin and Tweedie. Local information supplied to Darwin by residents such as Tweedie was clearly important and deserves further attention.

En la provincia de Buenos Aires el sistema ha sido profundamente modificado en los últimos 15 años siguiendo las premisas de la Convención Internacional sobre los Derechos del Niño y dejando relegado el modelo del Patronato, que había regido previamente. Las instituciones encargadas de la ejecución de la intervención dispuesta por el Poder Judicial dependen actualmente de la Subsecretaria de Niñez y Adolescencia del Ministerio de Desarrollo Social y constan de centros cerrados, centros con régimen de semilibertad y centros de intervención ambulatoria (medidas alternativas a la prisión, tales como suspensión de juicio a prueba o tareas comunitarias. Las ciencias relacionadas con la salud mental y con el comportamiento vienen contribuyendo a la identificación de diversos factores influyentes en la conducta disocial y con el diseño de tipos de intervención para cada nivel de prevención. Sin embargo, hay una distancia importante entre las potencialidades del estado actual delconocimiento y la implementación. En las condiciones expuestas, queda configurado un período de transición que aún requiere optimización de la política de infancia con ajustes legislativos, judiciales y administrativos y con la capitalización de los aportes científicos.

Backwater Flooding in San Marcos, TX from the Blanco River

Earl, Richard; Gaenzle, Kyle G.; Hollier, Andi B.

2016-01-01

Large sections of San Marcos, TX were flooded in Oct. 1998, May 2015, and Oct. 2015. Much of the flooding in Oct. 1998 and Oct. 2015 was produced by overbank flooding of San Marcos River and its tributaries by spills from upstream dams. The May 2015 flooding was almost entirely produced by backwater flooding from the Blanco River whose confluence is approximately 2.2 miles southeast of downtown. We use the stage height of the Blanco River to generate maps of the areas of San Marcos that are lower than the flood peaks and compare those results with data for the observed extent of flooding in San Marcos. Our preliminary results suggest that the flooding occurred at locations more than 20 feet lower than the maximum stage height of the Blanco River at San Marcos gage (08171350). This suggest that the datum for either gage 08171350 or 08170500 (San Marcos River at San Marcos) or both are incorrect. There are plans for the U.S. Army Corps of Engineers to construct a Blanco River bypass that will divert Blanco River floodwaters approximately 2 miles farther downstream, but the $60 million price makes its implementation problematic.

Se censaron las heces en varias plazas cada año en un único día entre 1991-2006. A partir del año 2000 se censaron heces en veredas circundantes. En cada plaza se seleccionaron al azar 30 heces frescas que se conservaron en formol 5% para su análisis parasitológico por el método de flotación de Willis con solución saturada de ClNa. Los 51 censos presentaron una mediana de heces de 288; un 82% de las heces se observaron en los canteros de tierra o pasto. La contaminación fecal en las plazas fue mayor en el período 2000-06 que en el anterior (p = 0.0000. La contaminación fecal de las plazas aumentó con la densidad humana en las manzanas lindantes (p = 0.0076. Las veredas mostraron un patrón inverso, ya que la contaminación fecal fue mayor en las áreas menos densamente pobladas (p = 0.0000. Se detectaron parásitos en un número variable de las heces colectadas en todas las plazas. Los géneros más frecuentes fueron Ancylostoma (20.47%, Trichuris (2.59% y Toxocara (1.70%. Nuestros resultados indican un aumento en la contaminación fecal de las plazas, posiblemente asociado con el aumento del número de perros en la ciudad combinado con las deficiencias en la implementación y el seguimiento de las medidas de control.

Full Text Available El articulo es una relectura de los acontecimientos de los primeros años postrevolucionarios en el Plata. Centrado en las fiestas mayas, las analiza como uno de los elementos claves en la constitución de nuevas formas de imaginar la experiencia política iniciada en 1810. La comparación entre Buenos Aires y Salta, permite mostrar algunas de diferencias en las maneras de vivir estas fiestas "revolucionarias"; esas diferencias reflejan por supuesto realidades sociales y culturales bastante contrastadas.

Full Text Available El presente estudio aborda los vínculos entre la socialización territorial y la movilidad social intergeneracional de hogares en la Región Metropolitana de Buenos Aires (RMBA. Para ello, se analiza en qué medida la socialización territorial condiciona las posibilidades de movilidad social ascendente. Los datos utilizados provienen de la base de datos de la encuesta de Estratificación y movilidad social en la Argentina (2007 del Centro de Estudios de Opinión Pública (CEDOP, Instituto de Investigaciones Gino Germani – Universidad de Buenos Aires. Los hallazgos principales del estudio se centran en que las características de la socialización en las zonas de residencia juvenil, donde se construyen vínculos y configuran expectativas, favorecen o refuerzan patrones de movilidad según la herencia de clase. Asimismo, otra pauta que el estudio muestra es que si bien la educación sigue atada a los orígenes sociales y ligada al territorio, ejerce un efecto en las posibilidades y oportunidades en el camino de ascenso social. El presente estudio brinda elementos para sustentar la hipótesis de que el territorio tiene un peso específico propio en los procesos de estratificación social.

The thesis introduces the basic theory of Small-Angle neutron scattering, enumerates several approximate law. It simply describes the components of Small-Angle neutron spectrometer (SANS) and the parameters of SANS of Budapest Neutron Center (BNC) in Hungary. During the period of studying at Budapest Neutron Center in Hungary, the experiments of wavelength calibration was carried out with SIBE and the SANS experiments of sample Micelles. The experiments are briefly introduced. Pxy program is used to fit these datum, and the results of wavelength and sizes of sample Micelles are presented. (authors)

Holocene slip rates along the San Andreas Fault System in the San Gorgonio Pass and implications for large earthquakes in southern California

Science.gov (United States)

Heermance, Richard V.; Yule, Doug

2017-06-01

The San Gorgonio Pass (SGP) in southern California contains a 40 km long region of structural complexity where the San Andreas Fault (SAF) bifurcates into a series of oblique-slip faults with unknown slip history. We combine new 10Be exposure ages (Qt4: 8600 (+2100, -2200) and Qt3: 5700 (+1400, -1900) years B.P.) and a radiocarbon age (1260 ± 60 years B.P.) from late Holocene terraces with scarp displacement of these surfaces to document a Holocene slip rate of 5.7 (+2.7, -1.5) mm/yr combined across two faults. Our preferred slip rate is 37-49% of the average slip rates along the SAF outside the SGP (i.e., Coachella Valley and San Bernardino sections) and implies that strain is transferred off the SAF in this area. Earthquakes here most likely occur in very large, throughgoing SAF events at a lower recurrence than elsewhere on the SAF, so that only approximately one third of SAF ruptures penetrate or originate in the pass.Plain Language SummaryHow large are earthquakes on the southern San Andreas Fault? The answer to this question depends on whether or not the earthquake is contained only along individual fault sections, such as the Coachella Valley section north of Palm Springs, or the rupture crosses multiple sections including the area through the San Gorgonio Pass. We have determined the age and offset of faulted stream deposits within the San Gorgonio Pass to document slip rates of these faults over the last 10,000 years. Our results indicate a long-term slip rate of 6 mm/yr, which is almost 1/2 of the rates east and west of this area. These new rates, combined with faulted geomorphic surfaces, imply that large magnitude earthquakes must occasionally rupture a 300 km length of the San Andreas Fault from the Salton Sea to the Mojave Desert. Although many ( 65%) earthquakes along the southern San Andreas Fault likely do not rupture through the pass, our new results suggest that large >Mw 7.5 earthquakes are possible on the southern San Andreas Fault and likely

Full Text Available En este trabajo se resumen los estudios bioarqueológicos realizados en la colección osteológica del sitio Paso Mayor Y1S2 (partido de Coronel Pringles, Buenos Aires. Los análisis efectuados comprendieron diferentes etapas. En primer lugar se hizo un inventario de la colección y se relevaron algunas variables tafonómicas para conocer el estado general de conservación de los restos. Una segunda etapa estuvo orientada a determinar la estructura sexo-etaria de la muestra. Finalmente se efectuaron estudios de marcadores de estrés ocupacional y el relevamiento de algunas patologías de carácter infeccioso y traumático. En conjunto estos análisis muestran que en el sitio se inhumaron individuos subadultos y adultos de ambos sexos, los restos fueron enterrados de manera primaria y secundaria. La colección muestra un buen estado de conservación por lo que fue posible determinar la mayoría de los elementos óseos analizados. En cuanto a los estudios de marcadores de actividad física, estos indican la importancia de la actividad deambulatoria y el posible uso de sistemas de armas como el arco y flecha. Se registró una reacción perióstica en los miembros inferiores y un traumatismo en el esqueleto craneal. Finalmente se discute la información bioarqueológica del sitio con la publicada para otros sitios del área.

"Usinas de miedo" y esquizopolíticas en Buenos Aires

María Carman

2008-09-01

Full Text Available En este trabajo quiero reflexionar en torno a la construcción del miedo en Buenos Aires como una categoría que está implicando, como diría Hegel, un reconocimiento unilateral de actores involucrados. Interesa interrogarnos si los vecinos de clase media o alta que se “acuartelan” tras muros o rejas son los únicos que experimentan temor en nuestras ciudades signadas por la desigualdad o, por el contrario, es posible discernir los temores de los sectores populares, en franca sintonía con las políticas resueltamente contradictorias que implementa el poder local, que he de denominar esquizopolíticas. Por otra parte, me interesa analizar de qué modo las villas, asentamientos u ocupaciones ilegales son percibidos por el resto de la sociedad como usinas donde en apariencia se “generan” sujetos que provocan miedo, incertidumbre y desorden. Veremos también cómo la cultura y la naturaleza son construidas veladamente, desde ciertos proyectos, como antítesis del miedo.

Paula Ferrere

2009-10-01

Full Text Available The present work was developed in the West of Buenos Aires Province (Argentina with the objective of adjusting functions of biomass of individual trees, in their different compartments and in the understorey. Stands of Eucalyptus viminalis Labill. were identified, with ages between 4 and 14 years-old. Twenty-one individuals were felled with diameters ranging from 9,2 to 32,5 cm. Simple and multiple regression models were developed and volume, branch leaf and stem biomass were estimated. The best volume equations were based on lineal models and the most adequate behavior was obtained with d2. To estimate leaf, branch and stem, ln-ln models have been suggested, with diameter and h or only diameter. The leaf biomass presented the weakest adjustment. The distribution of trees biomass agrees with the bibliography. The proportion of crown biomass decreases with age; on the other hand, the proportion of stem biomass increases with age.

Eugenesia en Buenos Aires: discursos, prácticas, historiografía

Directory of Open Access Journals (Sweden)

Diego Armus

Full Text Available Resumen En la década de 1990, algunos estudios subrayaron la dominante presencia de la eugenesia positiva en la Argentina moderna. Enfatizaban en el lugar marginal que en los discursos eugenésicos tuvieron los violentos métodos de selección. En los últimos años esta perspectiva ha sido revisada, señalando la viscosidad conceptual de la eugenesia y la presencia de discursos eugenésicos negativos. Este artículo comenta estos avatares historiográficos y también se detiene en las narrativas que estas perspectivas han articulado respecto del problema de la esterilización y regulación del matrimonio de quienes padecían tuberculosis en Buenos Aires durante la primera mitad del siglo XX. Con ese ejemplo se intenta remarcar la necesidad de tensionar discursos y prácticas en cualquier empeño por entender el pasado.

Los ejemplares corresponden a las especies: Rachycentrum canadum, Elops saurus y Caulolatilus chrysops. Estos registros amplían significativamente el límite austral de su distribución. La presencia ocasional de estas especies está asociada al transporte de agua subtropical cálida proveniente de la plataforma continental brasilera. Esta hipótesis es probada mediante el análisis de imágenes satelitales de temperatura superficial del mar.We document the southern records of three species of tropical bony fishes along the coast of Buenos Aires Province, Argentina (CBAP, 36-38°S. Rachycentrum canadum, Elops saurus and Caulolatilus chrysops were caught by bottom-trawl commercial vessels. Records presented here significantly extend southward their latitudinal distribution from those previously reported. Using sea surface temperature satellite images we show a southward warm circulation event from Brazil as a putative factor to explain the occurrence of these bony fishes in the CBAP.

Full Text Available The last Argentine military dictatorship (1976-1983 has left deep marks in different spheres of the social, and education has not been the exception. A group of educational policies were carried out in the province of Buenos Aires that strongly transformed the senses of teaching. One of those policies has been the teacher education reform and the new course of studies for the Higher Teaching in 1977. From the advances of an ongoing research and the work on historical sources –programs, plans, regulations, government decrees, acts- we will analyse this teacher education policy as part of the teachers' work regulation and as a process of practice production.

As mentioned in multiple research studies conducted in different Latin American countries, the study of this recent and widespread phenomenon demands to highlight some of the common places that have caused the characterization of the economic life of the popular sectors. We propose some theoretical guidelines to reconsider such consumption and analyze the results of our still ongoing investigation regarding consumption and indebtedness in the lower sectors of the metropolitan area of Buenos Aires.

Cacao use and the San Lorenzo Olmec

Powis, Terry G.; Cyphers, Ann; Gaikwad, Nilesh W.; Grivetti, Louis; Cheong, Kong

2011-01-01

Mesoamerican peoples had a long history of cacao use—spanning more than 34 centuries—as confirmed by previous identification of cacao residues on archaeological pottery from Paso de la Amada on the Pacific Coast and the Olmec site of El Manatí on the Gulf Coast. Until now, comparable evidence from San Lorenzo, the premier Olmec capital, was lacking. The present study of theobromine residues confirms the continuous presence and use of cacao products at San Lorenzo between 1800 and 1000 BCE, and documents assorted vessels forms used in its preparation and consumption. One elite context reveals cacao use as part of a mortuary ritual for sacrificial victims, an event that occurred during the height of San Lorenzo's power. PMID:21555564

Posner, D.M.

1988-01-01

Marketing natural gas produced in the San Juan Basin of New Mexico and Colorado principally involves four gas pipeline companies with significant facilities in the basin. The system capacity, transportation rates, regulatory status, and market access of each of these companies is evaluated. Because of excess gas supplies available to these pipeline companies, producers can expect improved take levels and prices by selling gas directly to end users and utilities as opposed to selling gas to the pipelines for system supply. The complexities of transporting gas today suggest that the services of an independent gas marketing company may be beneficial to smaller producers with gas supplies in the San Juan Basin

Alejandra Potocko

2017-07-01

Full Text Available Resumen La cuenca del río Reconquista es una de las tres grandes cuencas de la Región Metropolitana de Buenos Aires (Argentina gravemente afectada por las inundaciones y por la contaminación. En tanto pieza territorial de la ciudad metropolitana, la cuenca Reconquista fue abordada en los documentos de planificación urbana que se elaboraron para la región durante la segunda mitad del siglo XX: el Plan Regulador de Buenos Aires, el Esquema Director Año 2000, el Estudio del Sistema Metropolitano Bonaerense y el Proyecto 90. Independientemente de que se hayan concretado o no, esas instancias de planificación ilustran las formas de pensar y operar en la cuenca, como un ámbito dentro de la ciudad, como un problema de alcance metropolitano y como una propuesta de transformación territorial, en tres momentos: el de las inundaciones y la hidráulica, el del medio ambiente y la calidad de vida, y el de la ecología y el paisaje, donde cambian las relaciones que se establecen entre la urbanización, el urbanismo y las cuencas hídricas.

La formación moral de los jóvenes de elite en circuitos de educación privada en Buenos Aires

Full Text Available Resumen Los procesos educativos que involucran a los sectores medios- -altos y altos de Buenos Aires son analizados a partir de dinámicas que explican la construcción de un entre-nos: circuitos educativos diferenciados (escuelas secundarias, universidades privadas, circuitos de sociabilidad selectos (clubes sociales y deportivos con "tradición" y "prestigio", elecciones educativas y trayectorias justificadas a partir de una serie de concepciones que nativamente funcionan como "valores" y analíticamente como solidaridades. Comprendemos esa dinámica como un esfuerzo de las instituciones y las familias destinado a reproducir una posición social a partir de una diferencia que se practica en términos morales y se encarna en los cuerpos jóvenes. El trabajo retoma un proceso de investigación etnográfica realizada entre jóvenes y familias de sectores medios altos y altos del Área Metropolitana de Buenos Aires, que busca comprender la reproducción de las posiciones desiguales y la producción de juventud "solidaria" como clave de la diferenciación social

Full Text Available La brucelosis canina, causada por Brucella canis, provoca epididimitis, atrofia testicular y esterilidad en los perros, mientras que en las hembras el síntoma principal es el aborto. La transmisión al hombre puede ser por contacto con el semen, orina, y/o fetos abortados de animales infectados. El presente estudio de tipo observacional de corte transversal, se realizó en caninos de barrios y asentamientos con alto índice de necesidades básicas insatisfechas (NBI en 8 áreas de la ciudad de Buenos Aires. Se estudiaron 219 perros, 184 hembras y 35 machos, que fueron negativos a la prueba de aglutinación con antígeno tamponado (BPAT, que descartó la infección con especies lisas del género Brucella. Sedetectaron anticuerpos anti-B. canis en 16 perros (7.3%, 9 hembras y 7 machos, este último dato es relevante ya que la orina de los machos es considerada uno de los medios de diseminación de la infección. Aunque sólo se pudieron tomar hemocultivos a 175 animales, en 3 (2 hembras y un macho se aislaron B. canis. Sólo 3 de los dueños de los perros positivos accedieron al diagnóstico serológico y dos resultaron positivos. Destacamos que la prueba de inmunodifusión en gel de agar (IGDA ha demostrado ser poco sensible, detectó sólo uno de los 16 casos positivos y ninguno de los tres confirmados por aislamiento. Concluimos que en las áreas estudiadas el hallazgo de perros serológicamente positivos y el aislamiento de B. canis en 3 casos, son indicadores del riesgo en el que se encuentra la salud de la población expuesta.Canine brucellosis, caused by Brucella canis, provokes epidydimitis, testicular atrophy and sterility in male dogs, while in females the major symptom is miscarriage.

Full Text Available The aim of this paper is to analyze the conceptions of poverty that circulated among the elites of Buenos Aires through the eighteenth and early nineteenth centuries. At first the privileged groups of the city collected the tradition of Ius Commune to qualify certain groups of the lower classes as miserables worthy of charity. But in the last decades of the colonial rule, there was a different reception of new speeches among royal authorities, council elite and intellectuals, and appeared the suspicion that among the dispossessed there was fertile ground for laziness and reluctance to work. So new projects and courses of action took place.

Full Text Available Este artículo estudia el proceso de construcción de las parroquias rurales de Buenos Aires a lo largo de casi un siglo. Analiza esta gradual extensión de la red parroquial desde 1730 –la creación de los primeros curatos– hasta la década de 1820 cuando la Iglesia experimentaría cambios decisivos en su configuración como consecuencia de las reformas rivadavianas. El trabajo apunta a dar cuenta de los ritmos diferenciales con que se organizó la red parroquial en distintas zonas de la campaña bonaerense y a identificar los momentos más relevantes de los cambios en la misma. Asimismo examina el clero rural: su peso cuantitativo según áreas y períodos, su composición interna y algunos rasgos de las gestiones parroquiales. En especial considera aquellas acciones que los eclesiásticos exhibían entre sus mayores méritos y servicios, como modo de reconocer lo que –en la época– se esperaba de su actividad pastoral en la cura de almas

1995-01-01

The work performed since 1993 on the study of the elemental profile of Buenos Aires atmosphere is presented. Both aerosol direct sampling and biomonitors have been used and the samples have been analyzed mainly by Instrumental Neutron Activation Analysis (INAA). Due to problems with XRF, Anodic Stripping Voltammetry has been chosen for lead determination and Ion Chromatography for soluble anions. For aerosol direct sampling, analytical and sampling methods are described, as well as the sampling campaigns. Experiments have been performed for studying differences between day/night elemental concentrations along the week and a possible seasonal dependence. Some results of mass concentrations and others from INAA are presented. Sampling with the 'Gent sampler' began during August 1994 at an urban residential area of the city. The results of mass concentrations for the first 28 pairs of samples are shown together with some INAA results, as this is the only technique used for the analysis. Lichens and tree bark were the chosen biomonitors. Sampling and analytical methods by INAA are exposed, presenting some of the results that have been obtained. The participation in the aerosol analysis for the Ushuaia Global Atmospheric Watch Station is also commented. (author)

2007-01-01

Full Text Available En este escrito se analizan las instancias del proceso de transición hacia el Gobierno por Comunas en la Ciudad Autónoma de Buenos Aires, Argentina, con énfasis en el contexto político administrativo y legal, y en las formas que asume la participación mediante la descripción e interpretación de situaciones de interacción cara a cara en dos Comunas de la Ciudad. La división territorial de la Ciudad de Buenos Aires en Comunas, y la descentralización de algunas funciones del Gobierno de la Ciudad en los gobiernos comunales, son parte de los instrumentos y mecanismos de democracia participativa, definidos por la Constitución de la Ciudad de Buenos Aires del año 1996. El análisis nos permite ver que, si bien las Comunas fueron imaginadas como la herramienta más adecuada para concretar nuevas formas de organización democrática, a más de diez años de haberse aprobado dicha Constitución y habiendo superado largamente todos los plazos previstos, quienes componen la clase política han logrado postergar por más de 12 años la puesta en marcha de esta forma innovadora de gobierno local. Además, de distintas maneras han ido imponiendo la misma lógica política que el espíritu de la Constitución se proponía contrarrestar, es decir, se ha impuesto un nivel alto de concentración política en vez de garantizar una participación amplia, directa y no mediada por las estructuras político partidarias.

Full Text Available Green areas, also known as green infrastructure or urban vegetation, are vital to urbanites for their critical roles in mitigating urban heat island effects and climate change and for their provision of multiple ecosystem services and aesthetics. Here, I provide a high spatial resolution snapshot of the green cover distribution of the city of San Juan, Puerto Rico, by incorporating the use of morphological spatial pattern analysis (MSPA as a tool to describe the spatial pattern and connectivity of the city's urban green areas. Analysis of a previously developed IKONOS 4-m spatial resolution classification of the city of San Juan from 2002 revealed a larger area of vegetation (green areas or green infrastructure than previously estimated by moderate spatial resolution imagery. The city as a whole had approximately 42% green cover and 55% impervious surfaces. Although the city appeared greener in its southern upland sector compared to the northern coastal section, where most built-up urban areas occurred (66% impervious surfaces, northern San Juan had 677 ha more green area cover dispersed across the city than the southern component. MSPA revealed that most forest cover occurred as edges and cores, and green areas were most commonly forest cores, with larger predominance in the southern sector of the municipality. In dense, built-up, urban land, most of the green areas occurred in private yards as islets. When compared to other cities across the United States, San Juan was most similar in green cover features to Boston, Massachusetts, and Miami, Florida. Per capita green space for San Juan (122.2 m²/inhabitant was also comparable to these two U.S. cities. This study explores the intra-urban vegetation variation in the city of San Juan, which is generally overlooked by moderate spatial resolution classifications in Puerto Rico. It serves as a starting point for green infrastructure mapping and landscape pattern analysis of the urban green spaces

Full Text Available Sporadic amyotrophic lateral sclerosis (sALS is considered a multifactorial disease with genetic and environmental factors causing motor neuron degeneration. OBJECTIVE: To describe the epidemiological and occupational characteristics of patients with sALS who attended the Ramos Mejía Hospital at Buenos Aires, Argentina. METHOD: We analyzed the medical records of sALS patients diagnosed between 2001 and 2008. All occupations were coded according to the International Standard Classification of Occupation (ISCO. RESULTS: 187 patients were assessed, 38.5% were women and 61.5% men. Mean age at diagnosis was 55 years. 16% of them came from rural areas; 68% of the studied population had no health insurance. 40% were employed in elementary occupations, 19 were technicians and 8 handicraftsmen. CONCLUSION: The most represented profession was elementary occupation. A large proportion of patients came from rural areas, which might suggest an increased risk of environmental exposure to an unknown agent in those regions.

Los objetivos de este estudio fueron determinar los niveles circulantes de 25-hidroxi-vitamina D, 25(OHD, en pacientes ambulatorios ancianos y jóvenes de la ciudad de Buenos Aires y establecer el impacto de valores descendidos de Vitamina D en la remodelación ósea. Se evaluaron 83 ancianos y 76 jóvenes de 71.9±8.1 y 29.8±6.6 años respectivamente, mediante la medición de 25(OHD, parathormona medio-molecular y de marcadores del metabolismo óseo y mineral. En invierno se comprobaron valores de 25 (OH D en grado de insuficiencia en ambos grupos y un 14.2% de ancianos y 15.9% de jóvenes con valores menores de 10 ng/ml. En verano se observó un incremento de la 25(OHD en toda la población, sin embargo los niveles circulantes de Vitamina D no superaron los 40 ng/ml, en ambos grupos. Los niveles plasmáticos de parathormona fueron más elevados en ancianos que en jóvenes y en esa subpoblación se observó la presencia de hiperparatiroidismo secundario. La elevación de parathormona está condicionada por la deficiencia de vitamina D y otros factores adicionales como la edad, la insuficiencia renal y el grado de nutrición de la población. La remodelación ósea presentó variaciones estacionales: se incrementó en invierno en ambos grupos. En la ciudad de Buenos Aires se han observado niveles descendidos de Vitamina D en jóvenes y mayores, durante todo el año. Se deberán evaluar las políticas sanitarias apropiadas destinadas a corregir esta deficien-cia, la cual predispone a la osteoporosis.The purpose of this study was to evaluate the level of hypovitaminosis D in elderly and young outpatients populations of the City of Buenos Aires, and to establish its impact on bone remodeling.

1980-01-01

A review of historical sedimentation data is presented, results of sediment-data collection for water years 1957-59 are summarized, and long-term sediment-discharge estimates from a preliminary report are updated. Comparison of results based on 3 years of data to those for the 10 water years, 1957-66, provides an indication of the adequacy of the data obtained during the short period to define the long-term relation between sediment transport and streamflow. During 1909-66, sediment was transported to the entire San Francisco Bay system at an average rate of 8.6 million cubic yards per year. The Sacramento and San Joaquin River basins provided about 83% of the sediment inflow to the system annually during 1957-66 and 86% during 1909-66. About 98% of this inflow was measured or estimated at sediment measuring sites. Measured sediment inflow directly to the bays comprised only about 40% of the total discharged by basins directly tributary to the bays. About 90% of the total sediment discharge to the delta and the bays in the San Francisco Bay system thus was determined on the basis of systematic measurements. (USGS)

2011-12-01

Full Text Available The principal aim of this study was to provide a current description of the child and teenager maltreatment phenomenon in the Buenos Aires Province. The sample was composed by 5341 cases of children and teenagers from 0 to 20 years old, whose were treated in 2010 for having been victims of maltreatment. Physical maltreatment was the most frequent one. The girls presented major proportion of sexual abuse, whereas boys registered major proportions of negligence, physical maltreatment and desertion situation. An increase of the sexual abuse frequency in teenagers from 12 years was observed. As a whole, the information demonstrates that sex and age of victims are differentially associated with different types of maltreatment, and these are pertinent variables to have into account by future investigations, and prevention and protection organisms.

San Andreas tremor cascades define deep fault zone complexity

Science.gov (United States)

Shelly, David R.

2015-01-01

Weak seismic vibrations - tectonic tremor - can be used to delineate some plate boundary faults. Tremor on the deep San Andreas Fault, located at the boundary between the Pacific and North American plates, is thought to be a passive indicator of slow fault slip. San Andreas Fault tremor migrates at up to 30 m s-1, but the processes regulating tremor migration are unclear. Here I use a 12-year catalogue of more than 850,000 low-frequency earthquakes to systematically analyse the high-speed migration of tremor along the San Andreas Fault. I find that tremor migrates most effectively through regions of greatest tremor production and does not propagate through regions with gaps in tremor production. I interpret the rapid tremor migration as a self-regulating cascade of seismic ruptures along the fault, which implies that tremor may be an active, rather than passive participant in the slip propagation. I also identify an isolated group of tremor sources that are offset eastwards beneath the San Andreas Fault, possibly indicative of the interface between the Monterey Microplate, a hypothesized remnant of the subducted Farallon Plate, and the North American Plate. These observations illustrate a possible link between the central San Andreas Fault and tremor-producing subduction zones.

Hydrologic assessment and numerical simulation of groundwater flow, San Juan Mine, San Juan County, New Mexico, 2010–13

Stewart, Anne M.

2018-04-03

Coal combustion byproducts (CCBs), which are composed of fly ash, bottom ash, and flue gas desulfurization material, produced at the coal-fired San Juan Generating Station (SJGS), located in San Juan County, New Mexico, have been buried in former surface-mine pits at the San Juan Mine, also referred to as the San Juan Coal Mine, since operations began in the early 1970s. This report, prepared by the U.S. Geological Survey in cooperation with the Mining and Minerals Division of the New Mexico Energy, Minerals and Natural Resources Department, describes results of a hydrogeologic assessment, including numerical groundwater modeling, to identify the timing of groundwater recovery and potential pathways for groundwater transport of metals that may be leached from stored CCBs and reach hydrologic receptors after operations cease. Data collected for the hydrologic assessment indicate that groundwater in at least one centrally located reclaimed surface-mining pit has already begun to recover.The U.S. Geological Survey numerical modeling package MODFLOW–NWT was used with MODPATH particle-tracking software to identify advective flow paths from CCB storage areas toward potential hydrologic receptors. Results indicate that groundwater at CCB storage areas will recover to the former steady state, or in some locations, groundwater may recover to a new steady state in 6,600 to 10,600 years at variable rates depending on the proximity to a residual cone-of-groundwater depression caused by mine dewatering and regional oil and gas pumping as well as on actual, rather than estimated, groundwater recharge and evapotranspirational losses. Advective particle-track modeling indicates that the number of particles and rates of advective transport will vary depending on hydraulic properties of the mine spoil, particularly hydraulic conductivity and porosity. Modeling results from the most conservative scenario indicate that particles can migrate from CCB repositories to either the

Effectiveness of Kampo medicine Gorei-san for chronic subdural hematoma

Miyagami, Mitsusuke; Kagawa, Yukihide

2009-01-01

Chronic subdural hematomas (CSDHs) are basically treated by surgery. In some cases with no or minimum symptoms, however, they may be treated conservatively. In the present study, we evaluated the therapeutic effect of a Kampo medicine (Japanese traditional herbal medicine), Gorei-san, in the treatment of those CSDHs. Gorei-san 7.5 g t.i.d. was orally administered for 4 weeks in 22 patients with 27 CSDHs. Maximum thickness of the hematoma was followed up on CT scan for 4 to 29 weeks after administration of Gorei-san. In 7 of 22 patients, tranexamic acid and/or carbazochrome sodium sulfonate were also administrated. Gorei-san was effective in 23 of 27 CSDHs. In 12 of them, the hematoma was completely disappeared within 14 weeks after administration. In the other 11 CSDHs, the thickness was decreased. In those effective cases, thickness began to decrease 3 to 4 weeks after administration of Gorei-san. It was more effective in CSDHs with iso-/high or mixed density than with low density on CT. It was not effective in 4 out of 27 CSDHs. No apparent adverse effect was noted in the present series of patients. The present study suggests that a Kampo medicine, Gorei-san, is a useful option in the conservative treatment of CSDHs with no or minimum symptoms. (author)

Full Text Available El abastecimiento de sal en cantidades sufi cientes fue una de las principales preocupaciones del Cabildo de Buenos Aires. Fue este un producto de importancia vital no sólo por su aplicación en las comidas cotidianas, sino también por su aplicación en la conservación de las carnes y los cueros. Las características de su uso y su obtención, aumentaron su valor, no sólo comercial sino también estratégico. El hallazgo de yacimientos locales permitió a los habitantes de Buenos Aires abastecerse mediante la práctica de expediciones periódicas que fueron promovidas por las autoridades capitulares, lo que les permitió ejercer un mayor control sobre dicha producción. Como la actividad requería una importante capacidad de transporte y de mano de obra, era una práctica aprovechada por muchos para emplearse en ella y para obtener benefi cios con el comercio que se generaba en la oportunidad. Esto convertía a las expediciones a salinas, organizadas por las autoridades de la ciudad, en grandes caravanas que se internaban en pleno territorio indí-gena, involucrando un amplio conjunto de actores sociales tanto de la ciudad como de la campaña y el mundo indígena

Full Text Available Este trabajo analiza la actuación de médicos y policías durante la epidemia de fiebre amarilla que tuvo lugar en la ciudad de Buenos Aires en 1871. Aunque las embestidas de enfermedades infectocontagiosas fueron recurrentes durante el siglo XIX, la epidemia de fiebre amarilla constituye un quiebre, no solo por sus dimensiones cuantitativas y por los efectos materiales sobre la ciudad, sino también por las querellas que suscitó entre discursos en pugna. En particular, se intenta mostrar aquí cómo las figuras de los médicos y los policías fueron posicionadas en relación al tema del héroe y del sacrificado en cumplimiento del deber.

Transmission questioned. Youth, awareness, and memory of repression at Posadas Hospital, in Buenos Aires, Argentina

Emilio Crenzel

2011-07-01

Full Text Available This paper analyses popular wisdom and memory transmission regarding State terrorism and forced disappearance, which are circulating among youth living around Hospital Posadas, located in Haedo, a province to Buenos Aires, Argentina. At this hospital, there was, under the military dictatorship (1976-1983, a Clandestine Imprisonment Center, where people were kept prisoner as disappeared. Therefore, at this facility both practices of health restoration and torture and murder perpetration coexisted. Through thirty indepth interviews carried out among neighbor young people, the existence of manifold knowledge fractures and memory transmission about State violence is verified, being a result from the social relations breakthrough that used to articulate the neighborhood and the hospital, and from the material life conditions promoting undifferentiated historical and political time awareness.

Fumigating the Hygienic Model City: Bubonic Plague and the Sulfurozador in Early-Twentieth-Century Buenos Aires.

Science.gov (United States)

Engelmann, Lukas

2018-07-01

The 1899/1900 arrival of bubonic plague in Argentina had thrown the model status of Buenos Aires as a hygienic city into crisis. Where the idea of foreign threats and imported epidemics had dominated the thinking of Argentina's sanitarians at that time, plague renewed concerns about hidden threats within the fabric of the capital's dense environment; concerns that led to new sanitary measures and unprecedented rat-campaigns supported by the large-scale application of sulphur dioxide. The article tells the story of early twentieth-century urban sanitation in Buenos Aires through the lens of a new industrial disinfection apparatus. The Aparato Marot, also known as Sulfurozador was acquired and integrated in the capital's sanitary administration by the epidemiologist José Penna in 1906 to materialise two key lessons learned from plague. First, the machine was supposed to translate the successful disinfection practices of global maritime sanitation into urban epidemic control in Argentina. Second, the machine's design enabled public health authorities to reinvigorate a traditional hygienic concern for the entirety of the city's terrain. While the Sulfurozador offered effective destruction of rats, it promised also a comprehensive - and utopian - disinfection of the whole city, freeing it from all imaginable pathogens, insects as well as rodents. In 1910, the successful introduction of the Sulfurozador encouraged Argentina's medico-political elite to introduce a new principle of 'general prophylaxis'. This article places the apparatus as a technological modernisation of traditional sanitary practices in the bacteriological age, which preserved the urban environment - 'el terreno' - as a principal site of intervention. Thus, the Sulfurozador allowed the 'higienistas' to sustain a long-standing utopian vision of all-encompassing social, bodily and political hygiene into the twentieth century.

Full Text Available This article deals with the State regulation of drinking water and sanitation services in the Metropolitan Area of Buenos Aires. Its main objective is to identify the continuities and ruptures in State regulation during the transition from private management (1993-2006 to renationalisation and State management (2006 onwards. The concept of “State capacities” (both administrative and relational is used to assess regulatory performance. For the administrative capacities, the correspondence between the design and resources of the agencies, as well as the differences between their formal functions and actual practices, is examined. For the relational capacities, the policies of the National Government and its interaction with both the water and sanitation companies and the regulatory and control agencies are considered. The analysis is based on official documents, legislation and statistics, company balance sheets and reports, newspaper articles and semi-structured interviews.

2007-01-01

As part of a project which aims metal concentration assessment in urban park soils of Sao Paulo, in the present paper the concentration of the elements As, Ba, Cr, Co, Cu, Pb, Sb and Zn were determined in surface soil samples (0-5 cm and 0-20 cm) from Buenos Aires park of Sao Paulo. This park is located in central region of the city, and is surrounded by avenues and streets, with different traffic volumes. Instrumental Neutron Activation Analysis (INAA) and X-ray Fluorescence (FRX) were used for metal analysis. Preliminary results showed concentration levels of the analyzed elements higher than the values considered as reference values for soils in Sao Paulo, according to the Environmental Protection Agency of the State of Sao Paulo (CETESB). These results suggest that these elements have anthropogenic origin and indicate a potential risk for soil quality. (author)

"We talk of AIDS because we love life": a stakeholder assessment of HIV/AIDS organizations in Buenos Aires, Argentina.

Science.gov (United States)

Spaulding, Alicen B; Brieger, William R

This stakeholder assessment of HIV/AIDS service providing institutions in Argentina offers insights into the HIV/AIDS crisis in Spanish-speaking Latin America from an institutional level and makes recommendations for strengthening the work and functioning of these institutions. This stakeholder assessment was conducted to determine how HIV/AIDS prevention and management in Argentina affects and is affected by relevant HIV/AIDS institutions. Semi-structured qualitative interviews were conducted with 13 key leaders of organizations working in HIV/AIDS prevention in Buenos Aires including non-governmental, governmental, and academic institutions. Analyses of interviewee comments are presented according to four major themes: network connections, program resources, perceptions of success, and challenges. Key findings include the need for strengthening formal networks, increasing the involvement of other non-AIDS related social institutions in promoting HIV prevention, finding more sustainable funding options, working more effectively with the public sector to create policies and regulations favorable to the HIV/AIDS field, and addressing the lack of perceived susceptibility to HIV/AIDS in Argentine culture. From leaders' comments, recommendations are made for strengthening the HIV/AIDS network among key institutions including adapting the UNAIDS "Three Ones" principal to create one crosssector office responsible for coordinating HIV/AIDS work, formalizing agreements with institutions outside of Buenos Aires, increasing the role of schools in HIV/AIDS awareness, and designing programs that address lack of perceived susceptibility to HIV/AIDS among Argentines.

Chemical and Physical Characteristics of Pulverized Granitic Rock Adjacent to the San Andreas, Garlock and San Jacinto Faults: Implications for Earthquake Physics

Science.gov (United States)

Rockwell, T. K.; Sisk, M.; Stillings, M.; Girty, G.; Dor, O.; Wechsler, N.; Ben-Zion, Y.

2008-12-01

We present new detailed analyses of pulverized granitic rocks from sections adjacent to the San Andreas, Garlock and San Jacinto faults in southern California. Along the San Andreas and Garlock faults, the Tejon Lookout Granite is pulverized in all exposures within about 100 m of both faults. Along the Clark strand of the San Jacinto fault in Horse Canyon, the pulverization of granitic rocks is highly asymmetric, with a much broader zone of pulverization along the southwest side of the Clark fault. In areas where the granite is injected as dyke rock into schist, only the granitic rock shows pulverization, demonstrating the control of rock type on the pulverization process. Chemical analyses indicate little or no weathering in the bulk of the rock, although XRD analysis shows the presence of smectite, illite, and minor kaolinite in the clay-sized fraction. Weathering products may dominate in the less than 1 micron fraction. The average grain size in all samples of pulverized granitic rock range between about 20 and 200 microns (silt to fine sand), with the size distribution in part a function of proximity to the primary slip zone. The San Andreas fault samples are generally finer than those collected from along the Garlock or San Jacinto faults. The particle size distribution for all samples is non-fractal, with a distinct slope break in the 60-100 micron range, which suggests that pulverization is not a consequence of direct shear. This average particle size is quite coarser than previous reports, which we attribute to possible measurement errors in the prior work. Our data and observations suggest that dynamic fracturing in the wall rock of these three major faults only accounts for 1% or less of the earthquake energy budget.

Spatial distribution of ground-level urban background O3 concentrations in the Metropolitan Area of Buenos Aires, Argentina

International Nuclear Information System (INIS)

Pineda Rojas, Andrea L.; Venegas, Laura E.

2013-01-01

In this work, a recently developed urban-scale atmospheric dispersion model (DAUMOD-GRS) is applied to evaluate the ground-level ozone (O 3 ) concentrations resulting from anthropogenic area sources of NO x and VOC in the Metropolitan Area of Buenos Aires (MABA). The statistical comparison of model results with observations (including new available data from seventeen sites) shows a good model performance. Estimated summer highest diurnal O 3 1-h concentrations in the MABA vary between 15 ppb in the most urbanised area and 53 ppb in the suburbs. All values are below the air quality standard. Several runs are performed to evaluate the impact of possible future emission reductions on O 3 concentrations. Under all hypothetical scenarios, the maximum diurnal O 3 1-h concentration obtained for the area is slightly reduced (up to 4%). However, maximum diurnal O 3 concentrations could increase at some less urbanised areas of MABA depending on the relative reductions of the emissions of NO x and VOC. -- Highlights: ► A recently developed air quality model reproduces well observed O 3 levels in MABA. ► Modelled summer maximum diurnal O 3 concentrations vary in the area between 15 and 53 ppb. ► All hourly values are below the air quality standard (120 ppb). ► Possible future emission reductions would have small impact on the highest level. -- The distribution of summer maximum diurnal ground-level O 3 concentrations in the Metropolitan Area of Buenos Aires is evaluated applying a recently developed simple urban air quality model

A two-stage epidemiological study of eating disorders and muscle dysmorphia in male university students in Buenos Aires.

Compte, Emilio J; Sepulveda, Ana R; Torrente, Fernando

2015-12-01

Studies using traditional screening instruments tend to report a lower prevalence of eating disorders (EDs) in men than is observed in women. It is therefore unclear whether such instruments are valid for the assessment of ED in males. Lack of a formal diagnostic definition of muscle dysmorphia syndrome (MD) makes it difficult to identify men at risk. The study aimed to assess the prevalence of ED and MD in male university students of Buenos Aires. A cross-sectional, two-stage, representative survey was of 472 male students from six different schools in Buenos Aires, mostly aged between 18 and 28 years. The first stage involved administration of self-report questionnaires (Eating Attitude Test-26; scores ≥15 indicate "at risk" status). In Stage 2 students at risk of developing EDs were evaluated with a clinical interview, the Eating Disorder Examination (EDE; 12th edition). Two control students were interviewed for every at risk student. The prevalence of EDs among university male students was 1.9% (n = 9). All participants with an ED presented with illness classified as eating disorder not otherwise specified (EDNOS). Using the Drive for Muscularity Scale (DMS) with a 52-point threshold we identified possible MD in 6.99% (n = 33) of the sample. The prevalence of ED detected in this study is comparable with previous findings in male populations, and below that observed in female populations. However, the prevalence of possible cases of MD resembles the total rate of EDs in women. Characteristics associated with EDs and MD in men are also discussed. © 2015 Wiley Periodicals, Inc.

Full Text Available From the perspective of urbanism, the beginning of the twenty-first century in the metropolitan region of Buenos Aires has been characterized for the emergence of large-scale projects developed by private actors. Among them stand out private cities and commercial and services areas, called new centralities. Both urban designs are in close connection and require effective mobility conditions for its concretion. The intervention of private agents has impacted in the territorial transformations, creating a "parallel urban system" in the region, oriented towards attracting residents with a high socio-economic status. However, the traditional network of cities has not disappeared and, with the juxtaposition of this new system of private urbanism, it deepened the conditions of spatial fragmentation and social segregation. Desde la perspectiva del urbanismo, el comienzo del siglo XXI se caracteriza por la aparición en la región metropolitana de Buenos Aires, de proyectos de gran envergadura desarrollados por agentes privados. Entre ellos sobresalen las ciudades privadas y las áreas comerciales y de servicios, denominadas nuevas centralidades. Ambos diseños urbanos se mantienen en estrecha relación y requieren de eficaces condiciones de movilidad para su concreción y para su exitoso funcionamiento. La intervención de los agentes privados ha impactado en las transformaciones territoriales, creando un “sistema urbano paralelo” en la región, orientado a la captación de residentes con un alto nivel socio-económico. No obstante, la red de ciudades pre-existente no ha desaparecido y con la yuxtaposición de este nuevo sistema de urbanismo privado, se profundizan las condiciones de fragmentación espacial y de segregación social.

Full Text Available This article is intent on analizing the squatter phenomenon in the city of Buenos Aires since the return of the democratic government in 1983.

In fact, if this phenomenon has been regarded as such in the past years, it was due to an increasingly restrictive policy concerning this phenomenon, which was manifested not only in readily evicting strategies, but also in the dramatic lack of satisfactory housing policies for the aforementioned population.

Full Text Available En este trabajo analizamos las medidas que se intentaron implementar en Buenos Aires entre 1740 y 1776 para ordenar el aseo urbano. El tema será abordado tanto desde los lineamientos ideológicos y científicos que le dieron una forma específica a las órdenes emitidas, como desde los distintos dispositivos implementados para lograr su cumplimiento. Analizando estas cuestiones, será posible repensar sobre las diversas representaciones existentes en torno a la forma y la organización que una ciudad ideal del siglo XVIII debía alcanzar; además las medidas enunciadas podrán insertarse dentro de una trama más amplia de intereses de tipo político que se evidenciaron en la organización de la vida cotidiana.This paper analyzes the measures civil servants tried to implement in the city of Buenos Aires during 1740-1776 in order to improve the urban cleanliness. The subject will be approached taking into account the ideological and scientific positions that shaped the orders issued, and also the different devices implemented to enforce them. By studying these topics, we will be able to rethink the different representations an ideal city should reach in the eighteenth century. Additionally, the measures taken could be placed in a larger scenario of political interests to observe their impact in daily life.

Estimating natural recharge in San Gorgonio Pass watersheds, California, 1913–2012

Science.gov (United States)

Hevesi, Joseph A.; Christensen, Allen H.

2015-12-21

A daily precipitation-runoff model was developed to estimate spatially and temporally distributed recharge for groundwater basins in the San Gorgonio Pass area, southern California. The recharge estimates are needed to define transient boundary conditions for a groundwater-flow model being developed to evaluate the effects of pumping and climate on the long-term availability of groundwater. The area defined for estimating recharge is referred to as the San Gorgonio Pass watershed model (SGPWM) and includes three watersheds: San Timoteo Creek, Potrero Creek, and San Gorgonio River. The SGPWM was developed by using the U.S. Geological Survey INFILtration version 3.0 (INFILv3) model code used in previous studies of recharge in the southern California region, including the San Gorgonio Pass area. The SGPWM uses a 150-meter gridded discretization of the area of interest in order to account for spatial variability in climate and watershed characteristics. The high degree of spatial variability in climate and watershed characteristics in the San Gorgonio Pass area is caused, in part, by the high relief and rugged topography of the area.

Agreen, R. W.; Smith, D. E.

1974-01-01

The San Andreas fault experiment (Safe), which employs two laser tracking systems for measuring the relative motion of two points on opposite sides of the fault, has been simulated for an 8-yr observation period. The two tracking stations are located near San Diego on the western side of the fault and near Quincy on the eastern side; they are roughly 900 km apart. Both will simultaneously track laser reflector equipped satellites as they pass near the stations. Tracking of the Beacon Explorer C spacecraft has been simulated for these two stations during August and September for 8 consecutive years. An error analysis of the recovery of the relative location of Quincy from the data has been made, allowing for model errors in the mass of the earth, the gravity field, solar radiation pressure, atmospheric drag, errors in the position of the San Diego site, and biases and noise in the laser systems. The results of this simulation indicate that the distance of Quincy from San Diego will be determined each year with a precision of about 10 cm. Projected improvements in these model parameters and in the laser systems over the next few years will bring the precision to about 1-2 cm by 1980.

Disinfectant-resistant bacteria in Buenos Aires city hospital wastewater Resistência bacteriana a desinfetantes em efluentes de um hospital em Buenos Aires, Argentina

Directory of Open Access Journals (Sweden)

L. Nuñez

2007-12-01

Full Text Available Large quantities of disinfectants are used in hospitals, externally on human skin or to eliminate microorganisms from inanimate objects. After use, residual quantities of these products reach the wastewater, exposing the bacteria that survive in hospital wastewaters to a wide range of biocides that could act as a selective pressure for the development of resistance. Increasing attention has been directed recently to the resistance of bacteria to disinfectants. The aim of this paper was to determine the disinfectant bacterial resistance pattern of the microflora released to the urban sewer system by hospital effluents. The characterization of the waste water microflora was performed by determination of the CFU of heterotrophic bacteria, fecal indicator bacteria, Pseudomonas sp. and Staphylococcus sp., in a Buenos Aires hospital effluent. The bacterial resistance to the disinfectants more frequently used in the hospital practice, glutaraldehyde, chlorhexidine and povidone-iodine, was then evaluated. Disinfectant resistant bacterial strains were isolated and typified. Between 10³ and 10(6 chlorexidine resistant bacteria/100 mL were isolated from the samples. Bacteria resistant to other disinfectants ranged between 10³ and 10(4 /100 mL. The bacterial population resistant to desinfectants to was mainly composed by Enterobacteriaceae, Staphylococcus spp, and Bacillus spp, which are highly associated to nosocomial infections. The results obtained show that the hospital effluents are of importance in the bacterial resistance selection process, particularly in the case of disinfectants.Os hospitais utilizam uma grande quantidade de desinfetantes para eliminar microorganismos tanto da pele humana como de superfícies inanimadas.

Full Text Available This article presents and analyzes ethnographic data generated in Buenos Aires, the capital of Argentina, among soccer fans whose conduct is supposedly violent, and their relation to the police force. Using a theoretical framework proposed by authors working in the field of Melanesian anthropology, this text suggests that the police, with their insistence on establishing order and control, project an image of soccer fans as an unruly mob that rebels against police authority, thus leading to a neurotic escalation in the use of violence by the police. The fans, on the other hand, focus on their own supposedly heroic actions and leading roles as part of a process of individualization, and consider the police force an obstacle to the achievement of their goals, which leads them to act with even greater energy, to the point of hysteria, in their customary activities. Neurosis and hysteria are terms that are defined and used in a very specific way in this text.

The Infectious Diseases Hospital Francisco Javier Muñiz, Buenos Aires, Argentina, is the oldest in Latin America. It is over 100 years old and has a history worthy of pride. It became known as "Hospital of the pests" and was preceded by the old House of Insulation, which served as a quarantine station during epidemics of cholera, yellow fever and smallpox. The new House of Insulation, built in the neighborhood of Parque Patricios ("Barracks Hospital"), was renamed in 1904 in memory of Francisco Javier Muñiz, a former military doctor, naturalist and paleontologist. Its technical name is "Porteño Care Centre and National Reference Regional Infectious-Contagious Disease". It receives numerous national and foreign undergraduate and postgraduate students in its Departments of Infectious Diseases and Respiratory Diseases.

The instrument SANS-1 at the Geesthacht neutron facility GeNF was used for scattering experiments in 2000 at 196 of 200 days of reactor and cold source operation. The utilisation was shared between the in-house R and D program and user groups from different universities and research centers. These measurements were performed and analysed either by guest scientists or GKSS staff. The focus of the work in 2000 at the experiment SANS-1 was the structural investigation of hydrogen containing substances such as biological macromolecules (ribosomes, protein-RNA-complexes, protein solutions, glycolipids and membranes), molecules which are important in the fields of environmental research (refractoric organic substances) and technical chemistry (surfactants, micelles).

We report on SANS measurements carried out on the instrument SANS1 (V4) at the BENSC facility on solutions and composites of cellulose tricarbanilate (CTC). This cellulose derivative exhibits lyotropic behaviour in methylacrylate (MA). The SANS data indicate that in the isotropic liquid state (up to 25% wt CTC in MA) the CTC chains behave like rods of mass per unit length (M/L). In the liquid crystalline (LC) phase (at and above 35% wt CTC in MA), the Q dependence varies from Q sup - sup 1 to Q sup - sup 4 , probably as a result of self-assembling of the CTC chains. The general aim of our work is to prepare molecular composites, i.e. miscible blends of rigid-rod and flexible-coil polymers, from CTC solutions in polymerizable media. To establish the degree of homogeneity of the composites, we performed SANS measurements on UV-cured CTC/MA solutions. Here, we compare the SANS data of CTC/monomer solutions with those of the corresponding composites. (orig.)

Contemporary in situ tectonic stress indicators along the San Andreas fault system in central California show northeast-directed horizontal compression that is nearly perpendicular to the strike of the fault. Such compression explains recent uplift of the Coast Ranges and the numerous active reverse faults and folds that trend nearly parallel to the San Andreas and that are otherwise unexplainable in terms of strike-slip deformation. Fault-normal crustal compression in central California is proposed to result from the extremely low shear strength of the San Andreas and the slightly convergent relative motion between the Pacific and North American plates. Preliminary in situ stress data from the Cajon Pass scientific drill hole (located 3.6 kilometers northeast of the San Andreas in southern California near San Bernardino, California) are also consistent with a weak fault, as they show no right-lateral shear stress at approximately 2-kilometer depth on planes parallel to the San Andreas fault.

2009-12-01

The San Miguel volcano lies near the city of San Miguel, El Salvador (13.43N and -88.26W). San Miguel volcano, an active stratovolcano, presents a significant natural hazard for the city of San Miguel. Furthermore, the internal state and activity of volcanoes remains an important component to understanding volcanic hazard. The main technology for addressing volcanic hazards and processes is through the analysis of data collected from the deployment of seismic sensors that record ground motion. Six UTEP seismic stations were deployed around San Miguel volcano from 2007-2008 to define the magma chamber and assess the seismic and volcanic hazard. We utilize these data to develop images of the earth structure beneath the volcano, studying the volcanic processes by identifying different sources, and investigating the role of earthquakes and faults in controlling the volcanic processes. We will calculate receiver functions to determine the thickness of San Miguel volcano internal structure, within the Caribbean plate. Crustal thicknesses will be modeled using calculated receiver functions from both theoretical and hand-picked P-wave arrivals. We will use this information derived from receiver functions, along with P-wave delay times, to map the location of the magma chamber.

In 2007, the California Ocean Protection Council initiated the California Seafloor Mapping Program (CSMP), designed to create a comprehensive seafloor map of high-resolution bathymetry, marine benthic habitats, and geology within the 3-nautical-mile limit of California's State Waters. The CSMP approach is to create highly detailed seafloor maps through collection, integration, interpretation, and visualization of swath sonar data, acoustic backscatter, seafloor video, seafloor photography, high-resolution seismic-reflection profiles, and bottom-sediment sampling data. The map products display seafloor morphology and character, identify potential marine benthic habitats, and illustrate both the surficial seafloor geology and shallow (to about 100 m) subsurface geology. The Offshore of San Gregorio map area is located in northern California, on the Pacific coast of the San Francisco Peninsula about 50 kilometers south of the Golden Gate. The map area lies offshore of the Santa Cruz Mountains, part of the northwest-trending Coast Ranges that run roughly parallel to the San Andreas Fault Zone. The Santa Cruz Mountains lie between the San Andreas Fault Zone and the San Gregorio Fault system. The nearest significant onshore cultural centers in the map area are San Gregorio and Pescadero, both unincorporated communities with populations well under 1,000. Both communities are situated inland of state beaches that share their names. No harbor facilities are within the Offshore of San Gregorio map area. The hilly coastal area is virtually undeveloped grazing land for sheep and cattle. The coastal geomorphology is controlled by late Pleistocene and Holocene slip in the San Gregorio Fault system. A westward bend in the San Andreas Fault Zone, southeast of the map area, coupled with right-lateral movement along the San Gregorio Fault system have caused regional folding and uplift. The coastal area consists of high coastal bluffs and vertical sea cliffs. Coastal promontories in

N,N-dimethyldodecylamine-N-oxide (C12NO) is a surfactant that may exist either in a neutral or protonated form depending on the pH of aqueous solutions. Using small angle X-ray diffraction (SAXD) we demonstrate structural responsivity of C12NO/dioleoylphospha-tidylethanolamine (DOPE)/DNA complexes designed as pH sensitive gene delivery vectors. Small angle neutron scattering (SANS) was employed to follow kinetics of C12NO protonization and DNA binding into C12NO/DOPE/DNA complexes in solution of 150 mM NaCl at acidic condition. SANS data analyzed using paracrystal lamellar model show the formation of complexes with stacking up to ∼32 bilayers, spacing ∼ 62 Å, and lipid bilayer thickness ∼37 Å in 3 minutes after changing pH from 7 to 4. Subsequent structural reorganization of the complexes was observed along 90 minutes of SANS mesurements.

N,N-dimethyldodecylamine-N-oxide (C 12 NO) is a surfactant that may exist either in a neutral or protonated form depending on the pH of aqueous solutions. Using small angle X-ray diffraction (SAXD) we demonstrate structural responsivity of C 12 NO/dioleoylphospha-tidylethanolamine (DOPE)/DNA complexes designed as pH sensitive gene delivery vectors. Small angle neutron scattering (SANS) was employed to follow kinetics of C 12 NO protonization and DNA binding into C 12 NO/DOPE/DNA complexes in solution of 150 mM NaCl at acidic condition. SANS data analyzed using paracrystal lamellar model show the formation of complexes with stacking up to ∼32 bilayers, spacing ∼ 62 Å, and lipid bilayer thickness ∼37 Å in 3 minutes after changing pH from 7 to 4. Subsequent structural reorganization of the complexes was observed along 90 minutes of SANS mesurements. (paper)

Geologic Map of the San Luis Quadrangle, Costilla County, Colorado

Machette, Michael N.; Thompson, Ren A.; Drenth, Benjamin J.

2008-01-01

The map area includes San Luis and the primarily rural surrounding area. San Luis, the county seat of Costilla County, is the oldest surviving settlement in Colorado (1851). West of the town are San Pedro and San Luis mesas (basalt-covered tablelands), which are horsts with the San Luis fault zone to the east and the southern Sangre de Cristo fault zone to the west. The map also includes the Sanchez graben (part of the larger Culebra graben), a deep structural basin that lies between the San Luis fault zone (on the west) and the central Sangre de Cristo fault zone (on the east). The oldest rocks exposed in the map area are the Pliocene to upper Oligocene basin-fill sediments of the Santa Fe Group, and Pliocene Servilleta Basalt, a regional series of 3.7?4.8 Ma old flood basalts. Landslide deposits and colluvium that rest on sediments of the Santa Fe Group cover the steep margins of the mesas. Rare exposures of the sediment are comprised of siltstones, sandstones, and minor fluvial conglomerates. Most of the low ground surrounding the mesas and in the graben is covered by surficial deposits of Quaternary age. The alluvial deposits are subdivided into three Pleistocene-age units and three Holocene-age units. The oldest Pleistocene gravel (unit Qao) forms extensive coalesced alluvial fan and piedmont surfaces, the largest of which is known as the Costilla Plain. This surface extends west from San Pedro Mesa to the Rio Grande. The primary geologic hazards in the map area are from earthquakes, landslides, and localized flooding. There are three major fault zones in the area (as discussed above), and they all show evidence for late Pleistocene to possible Holocene movement. The landslides may have seismogenic origins; that is, they may be stimulated by strong ground shaking during large earthquakes. Machette and Thompson based this geologic map entirely on new mapping, whereas Drenth supplied geophysical data and interpretations.

Full Text Available In Buenos Aires the “otherness” of Peruvian immigrants is structured around manifestations of discrimination that come from the host society. Our purpose is to analyze immigrant foods and the representations they evoke, as well as to investigate the way in which their cooking acquires new meanings in new contexts, showing a tendency to become a mark of specificity and a way to resist the hostility of the host society. In order to do this, we focus on Peruvian restaurants and specifically ‘exocuisine’ or eating out, as opposed to ‘endocuisine’ or eating in. By starting with an analysis of meals and commensality practices in the ‘eating-out’ context, we aim to account for the processes of construction-reconstruction of relationships among Peruvians as well as between Peruvians and Argentines when eating in restaurants. Our objective we is to highlight the role that restaurants have been performing among immigrants, exploring the expansion of the Peruvian culinary vocabulary and identifying the changes in the social and cultural functions of food. In addition, following the rise of Peruvian cuisine at international level in recent years, we return to the field after nearly nine years in order to register the new meanings it acquires in the local context and how this influences the dialogue between immigrants and the host society.L'immigration péruvienne à Buenos Aires s'inscrit dans un contexte d'accentuation des discriminations envers les différentes communautés rejetées par l'Etat nation argentin.

Resistance Management for San Jose Scale (Hemiptera: Diaspididae).

Science.gov (United States)

Buzzetti, K; Chorbadjian, R A; Nauen, R

2015-12-01

The San Jose scale Diaspidiotus perniciosus Comstock is one of the most important pests of deciduous fruit trees. The major cause of recent outbreaks in apple orchards is thought to be the development of insecticide resistance, specifically organophosphates. The first report was given in North America, and now, in Chile. In the present study, San Jose scale populations collected from two central regions of Chile were checked for their susceptibility to different mode of action insecticides in order to establish alternatives to manage this pest. No evidence of cross resistance between organophosphates insecticides and acetamiprid, buprofezin, pyriproxyfen, spirotetramat, sulfoxaflor, or thiacloprid was found. Baselines of LC50-LC95 for different life stages of San Jose scale are given, as reference to future studies of resistance monitoring. The systemic activity of acetamiprid, spirotetramat, and thiacloprid was higher than the contact residue effect of these compounds. For sulfoxaflor, both values were similar. Program treatments including one or more of these compounds are compared in efficacy and impact on resistance ratio values. In order to preserve new insecticides as an important tool to control San Jose scale, resistance management programs should be implemented, considering insecticide mode of action classes alternated or mixed. © The Authors 2015.

Full Text Available We report a new record of Lithobates catesbeianus (American bullfrog from Argentina. L. catesbeianus was first introduced to San Juan Province 11 years ago in Calingasta Department, where the habitat is pre-cordilleran. The new record is for Zonda Department, San Juan Province, in the Monte desert region. Here, L. catesbeianus uses artificial ponds for reproduction and tadpole development. These ponds receive water from an irrigation system that connects the whole agriculture land in the region. The tadpoles use the irrigation canals to move among ponds. We suggest that legislation should be established to prevent future invasions and to achieve sustainable management of the wild American bullfrog populations in San Juan. Prevention of future invasion and management of established populations of this species requires the cooperation of numerous stake holders.Se presenta un nuevo registro de Lithobates catesbeianus (rana toro americana en Argentina.

Structure of the 1906 near-surface rupture zone of the San Andreas Fault, San Francisco Peninsula segment, near Woodside, California

Rosa, C.M.; Catchings, R.D.; Rymer, M.J.; Grove, Karen; Goldman, M.R.

2016-07-08

High-resolution seismic-reflection and refraction images of the 1906 surface rupture zone of the San Andreas Fault near Woodside, California reveal evidence for one or more additional near-surface (within about 3 meters [m] depth) fault strands within about 25 m of the 1906 surface rupture. The 1906 surface rupture above the groundwater table (vadose zone) has been observed in paleoseismic trenches that coincide with our seismic profile and is seismically characterized by a discrete zone of low P-wave velocities (Vp), low S-wave velocities (Vs), high Vp/Vs ratios, and high Poisson’s ratios. A second near-surface fault strand, located about 17 m to the southwest of the 1906 surface rupture, is inferred by similar seismic anomalies. Between these two near-surface fault strands and below 5 m depth, we observed a near-vertical fault strand characterized by a zone of high Vp, low Vs, high Vp/Vs ratios, and high Poisson’s ratios on refraction tomography images and near-vertical diffractions on seismic-reflection images. This prominent subsurface zone of seismic anomalies is laterally offset from the 1906 surface rupture by about 8 m and likely represents the active main (long-term) strand of the San Andreas Fault at 5 to 10 m depth. Geometries of the near-surface and subsurface (about 5 to 10 m depth) fault zone suggest that the 1906 surface rupture dips southwestward to join the main strand of the San Andreas Fault at about 5 to 10 m below the surface. The 1906 surface rupture forms a prominent groundwater barrier in the upper 3 to 5 m, but our interpreted secondary near-surface fault strand to the southwest forms a weaker barrier, suggesting that there has been less or less-recent near-surface slip on that strand. At about 6 m depth, the main strand of the San Andreas Fault consists of water-saturated blue clay (collected from a hand-augered borehole), which is similar to deeply weathered serpentinite observed within the main strand of the San Andreas Fault at

Recent earthquakes and a new way of looking at faults suggest that damaging earthquakes are closing in on the San Francisco area. Earthquakes Awareness Week 1989 in northern California started off with a bang on Monday, 3 April, when a magnitude 4.8 earthquake struck 15 kilometers northeast of San Jose. The relatively small shock-its primary damage was the shattering of an air-control tower window-got the immediate attention of three U.S Geological Survey seismologists in Menlo Park near San Francisco. David Oppenheimer, William Bakun, and Allan Lindh had forecast a nearby earthquake in a just completed report, and this, they thought, might be it.

Full Text Available The aim of this article is to identify measures that can prevent violent conflict through the maintenance of traditional cultural values that guide conflict avoidance. Moreover, the article focuses on the concepts of conflict prevention and conflict avoidance as applied by the San community of Platfontein. The causes of the inter-communal tensions between the San community members are also examined. A selected conflict situation, that of superstition and witchcraft, is assessed as factors increasing interpersonal conflict in the Platfontein community. This investigation is made to determine if the San preventive measures have an impact in the community, so as to prevent ongoing conflicts from escalating further.

This paper is an approach to AIDS as a topic among a drug abusers sample of the city of Buenos Aires. Research was carried out on the basis of a qualitative methodology. In an attempt at surveying opinions and attitudes of such a sample as regards AIDS (i.e. subjects' cognitive map), 21 drug abusers from three different rehabilitation programs operating in the B.A. area were interviewed. On the basis of the research performed, the authors elaborate communication strategies among drug abusers that would be helpful for authorities engaged in AIDS prevention to adopt. To boost a strategy likely to break up the AIDS-drug association existing in the mind of many an abuser would be highly advisable so that a separation be settled between both representations, thus giving drug abusers a higher motivation for self-care practice.

Full Text Available This paper studies how the characteristics of Latin American urban transportation generate dimensions of dispute of ‘spatial capital’, meaning an individually internalizable type of urban resource which results from the combination of objective material conditions and subjective socio-cultural conditions. These conditions determine a socially differentiated use of territory and sometimes are decisive elements in opening new niches for high-end real-estate producers and consumers, hence linking with processes of displacement and exclusion. The study cases compare four neighborhoods from Buenos Aires and Santiago de Chile, two peripherals and two pericentrals. The results show, considering the role of new infrastructure, a strong difference between residents from the peripheral cases and little difference in the pericentral cases, identifying, however, processes of a dispute over the ownership and use of urban space and the neighborhood, in all the cases.

Full Text Available Non-tuberculous mycobacteria (NTM have emerged as pathogens frequently associated to HIV co-infection. The aims of this study were to describe the clinical importance of NTM in patients from the North of Buenos Aires Province and the drug-susceptibility patterns in relation with the therapy used. A total of 23,624 clinical specimens were investigated during the period 2004-2010. Ziehl-Neelsen stain and cultures were used for diagnosis. Molecular and biochemical tests were performed to identify the mycobacteria. TB and mycobacterioses cases were 2 118 and 108 respectively. Sixteen NTM species were found: Mycobacterium avium and Mycobacterium intracellulare as the main causative agents. Infections produced by more than one species at the same time were confirmed (4 cases. Macrolides and fluoroquinolones were the most active in vitro drugs. Treatment evaluation showed that 68.0 % of the cases completed the therapy, 20 % died; and 12 % were relapses. The cases in which the treatment outcome was evaluated received an individual tailor-made therapeutic scheme including those drugs showing in vitro activity and presumed in vivo usefulness. More than a quarter of the patients had HIV co-infection and the majority of the deaths were associated with this co-infection.Enfermedad causada por micobacterias no tuberculosas: diagnóstico y evaluación del tratamiento en el norte del Gran Buenos Aires.

Full Text Available This article focuses on land conflicts in those "pueblos de indios" which were able to preserve their lands until the late nineteenth century in the jurisdiction of Cordoba. It is based on a case study: the Indian town of La Toma -which was settled near the city of Cordoba- between 1790 and 1825. More specifically, it reconstructs the attempts of the Spanish chapter, the jesuits and some landowners to occupy some pieces of land in the town, and to legalize the occupation. It also looks at the indigenous strategies for the defense of their land rights, which were supported by the Royal Audience of Buenos Aires which allowed them to avoid the restrictions imposed by local courts.A partir del estudio del caso de La Toma entre fines del siglo XVIII y principios del siglo XIX, se abordan los conflictos por las tierras de aquella parte de la población indígena encomendada y asentada en la jurisdicción de Córdoba, que fue reducida en "pueblos de indios" en el siglo XVII y que logró preservar el control sobre sus tierras comunales durante los dos siglos siguientes. Específicamente, se reconstruyen los intentos del cabildo, la Compañía de Jesús y los vecinos españoles por ocupar de hecho las tierras de ese pueblo de indios asentado en las cercanías de la ciudad de Córdoba y por legalizar esa situación, así como las estrategias indígenas de defensa de sus derechos, que contaron con el apoyo de los funcionarios la Real Audiencia de Buenos Aires y permitieron eludir las trabas impuestas por la justicia local.
