    Full Text Available Visceral Larva Migrans syndrome (VLM results from the presence or migration of helminth larvae in humans, who nonetheless only play the role of paratenic hosts in the helminths' life cycle. In humans, VLM can be caused by larvae of various nematode species, chiefly those of the ascarid Toxocara canis, which can then be found at a variety of body sites, such as the liver, lungs, heart, and brain. Clinical and pathological manifestations depend primarily on larvae number and location, infection duration, reinfection occurrence, and host's immunological condition. Signs and symptoms may range from asymptomatic infection to severe disease. In humans, infection is acquired through ingestion of T. canis eggs present in soil, containing larvae in the infective stage7, 8, 9. Indeed, eggs of Toxocara sp. have been found in sandboxes in several public places in the city of Campo Grande, Mato Grosso do Sul state2. This study was carried out to detect the presence of anti-Toxocara antibodies in children attending the Pediatrics division of Hospital Universitário of Universidade Federal de Mato Grosso do Sul at Campo Grande, Brazil. Over the years 1992-94, 454 serum samples, obtained from children of 5.25 ± 3.28 years of mean age and selected at that hospital on the basis of eosinophil count greater than or equal to 1000/mm3 of blood, were tested for the presence of antibodies by means of the ELISA technique employing Toxocara canis larvae excretory-secretory antigens5. A high prevalence rate for toxocariasis (35.55% was found, which was observed to be associated with eosinophil levels lower than those usually reported in literature. Furthermore, a higher frequency of positive serology among boys was also observed (13 cases in contrast to only 3 among girls, a result also reported by other authors

    Full Text Available Infection by Pseudomonas aeruginosa has spread worldwide, with limited options for treatment. The purpose of this study was to investigate metallo-β-lactamase-producing P. aeruginosa strains and compare their genetic profile using samples collected from patients in intensive care units. Forty P. aeruginosa strains were isolated from two public hospitals in Campo Grande, Mato Grosso do Sul State, from January 1st, 2007 to June 31st, 2008. Profiles of antimicrobial susceptibility were determined using the agar diffusion method. Metallo-β-lactamase was investigated using the double-disk diffusion test and PCR. Molecular typing was performed by pulsed-field gel electrophoresis (PFGE. Respiratory and urinary tracts were the most common isolation sites. Of the 40 samples tested, 72.5% (29/40 were resistant to ceftazidime and 92.5% (37/40 to imipenem, whereas 65% (26/40 were resistant to both antimicrobials. Fifteen pan-resistant samples were found. Five percent (2/40 of samples were positive for metallo-β-lactamase on the phenotype test. No metallo-β-lactamase subtype was detected by PCR. Macrorestriction analysis revealed 14 distinct genetic patterns. Based on the superior accuracy of PCR, it can be inferred that P. aeruginosa isolates from the investigated hospitals have alternative mechanisms of carbapenem resistance. The results also suggest clonal spread of P. aeruginosa between the studied hospitals.

    Full Text Available A violência, em todas as suas apresentações, tem crescido de forma avassaladora no país, elevando os indicadores de morbidade e mortalidade por causas externas. O uso das armas de fogo, muitas vezes, faz vítimas fatais ou que podem permanecer sequeladas. Tal fato tem aumentado o ônus do estado com internações hospitalares e acréscimo dos anos de vida perdidos da população jovem, que constitui a grande maioria dessas vítimas. Nesse sentido, o presente estudo objetivou fazer um levantamento das vítimas de ferimentos por arma de fogo, atendidas pelo Serviço de Atendimento Móvel de Urgência no município de Campo Grande-MS, no período de abril de 2005 a abril de 2007, nos dois primeiros anos de funcionamento, desde a implantação desse serviço na capital do Estado de Mato Grosso do Sul. Realizou-se estudo descritivo, baseado em análise documental do sistema de informação do SAMU do município de Campo Grande-MS. Foram descritos 233 atendimentos. Os resultados evidenciaram 213 vítimas do sexo masculino, a faixa etária mais acometida foi dos 20 aos 24 anos de idade, a cabeça e o pescoço foram as partes do corpo mais atingidas e a região Sul do município de Campo Grande foi a que concentrou maior número de atendimentos. Conclui-se que a violência por arma de fogo em Campo Grande-MS atinge a camada economicamente ativa da população e provém de regiões de bolsões de pobreza e desigualdade social, justificando a implantação de um serviço como o SAMU.Violence has grown in an overwhelming way in Brazil, raising the indicators of morbidity and mortality by external causes.

    Full Text Available This study aims to analyze purchase policies to fruits and vegetables in supermarkets in Campo Grande, Brazilian Midwest. Thirteen interviews were conducted with representatives from supermarkets, small, medium and large, responsible for purchasing fresh vegetables. By analyzing the responses obtained through interviews, we can observe that producers make almost the entire supply of fruits and vegetables in large supermarkets from other states, and the small and medium establishments usually buy more with the local producer. For retailers, the fruits and vegetables represent an important factor to create internal circulation of customers in stores and a factor of attraction of clients too, in addition, this products offer high profitability. For the supermarket, the fruits and vegetables locally produced are fresher and have lower comparative cost. However, supply regularity, the volume and variety offered by local producers are considered unsatisfactory.O presente estudo objetiva analisar as formas de compra dos supermercados para o abastecimento de hortaliças em Campo Grande. Foram realizadas treze entrevistas com representantes de supermercados de pequeno, médio e grande porte, responsáveis pelas compras destes produtos. Os resultados revelam que praticamente todo o fornecimento de hortaliças nos grandes supermercados é feito por produtores de outros estados, sendo que os estabelecimentos de pequeno e médio porte ainda conseguem abastecer-se satisfatoriamente com os produtores locais. Para os varejistas, o setor de hortaliças representa importante espaço de geração de tráfego interno de clientes nas lojas, sendo um fator de atração. Pode-se verificar, ainda, que as hortaliças produzidas localmente atendem ao requisito "frescor" e também possuem menor custo comparativo, porém, a regularidade no fornecimento, o volume e a variedade oferecida pelos produtores locais são considerados insatisfatórios.

O método "bottom-up" foi utilizado para os cálculos das emissões gasosas. Os estudos realizados permitem inferir que a substituição do diesel pelo biodiesel resultaria em diminuição das emissões de poluentes, geração de novos postos de empregos a partir de atividades agrícolas e industriais, e a diminuição na importação de petróleo, já que o Brasil importa petróleo, basicamente, para suprir a demanda de diesel.The present work deals with the estimation of the atmospheric pollutants emitted monthly in Campo Grande/MS by buses and minibuses, which employ diesel, biodiesel or natural gas as fuels. For the gaseous emissions calculations was used a "bottom-up" technique.

    Full Text Available O crescimento do contingente populacional das cidades requer o gerenciamento eficiente dos recursos hídricos, particularmente quando a exploração de novas fontes de abastecimento mostra-se dispendiosa e os recursos naturais cada vez mais escassos. Em contrapartida, em diversas cidades brasileiras, são comuns redes de distribuição de água para abastecimento com elevados índices de perdas, sejam elas não-físicas ou físicas (perdas por vazamento. O presente estudo visa avaliar as perdas por vazamentos de um setor da rede de distribuição de água da cidade de Campo Grande-MS. Para tanto, utiliza-se um procedimento iterativo de avaliação hidráulica que considera as perdas por vazamento e a dependência das demandas com a pressão, utilizando o simulador hidráulico EPANET 2 (Rossman, 2000, com vistas à calibração em termos dos parâmetros do modelo de vazamentos, bem como dos coeficientes de perda de carga localizada relativa a componentes hidráulicos presentes na rede. Para a resolução do problema inverso correspondente são utilizados os Algoritmos Genéticos (AGs.The increasing population of the cities requires an efficient water resources management, particularly when new supply source explorations are costly and natural resources are growing scarce.

    Rickettsia infection of each tick was evaluated by the hemolymph test and polymerase chain reaction (PCR) targeting gltA and ompA genes. All hemolymph tests were negative and PCR of one A. dubitatum detected both Rickettsia genes. Sequence of ompA exhibited a 99% identity with Rickettsia parkeri and R. africae and a 98% identity with R. sibirica. Rickettsia of the spotted fever group in A. dubitatum is described for the first time in an urban area within the municipality of Campo Grande in the state of Mato Grosso do Sul (MS), Brazil. This finding reinforces the importance of more detailed studies to determine the role of A. dubitatum in the transmission of spotted fever agents.

    The southern cattle fever tick, Rhipicephalus (Boophilus) microplus, is no doubt the most economically important ectoparasite of cattle globally. The inappropriate use of chemical acaricides has driven the evolution of resistance in populations of R. (B.) microplus. Anti-tick vaccines represent a technology that can be combined with acaricides in integrated control programs to mitigate the impact of R. (B.) microplus. The recombinant form of Bm86 antigen from the Campo Grande (rBm86-CG) strain of R. (B.) microplus was produced using the Pichiapastoris expression system to test its ability to immunoprotect cattle against tick infestation. Secretion of rBm86-CG by P. pastoris through the bioprocess reported here simplified purification of the antigen. A specific humoral immune response was detected by ELISA in vaccinated cattle. Immunoblot results revealed that polyclonal antibodies from vaccinated cattle recognized a protein in larval extracts with a molecular weight corresponding to Bm86. The rBm86-CG antigen showed 31% efficacy against the Campo Grande strain of R. (B.) microplus infesting vaccinated cattle. The rBm86-CG is an antigen that could be used in a polyvalent vaccine as part of an integrated program for the control of R. (B.) microplus in the region that includes Mato Grosso do Sul.

From 55 wild hosts including six different species (Nasua nasua, Cebus spp., Cerdocyon thous, Myrmecophaga tridactyla, Tamandua tetradactyla and Dasyprocta aguti, 323 ticks were collected. Amblyomma ovale ticks were found solely on coatis, and Amblyomma nodosum was identified solely on anteaters. No ticks were found on capuchin monkeys. However, Amblyomma cajennense was found on all parasitized host species with the exception of capuchin monkeys. Giant anteaters displayed the highest infestation abundance, with a mean of 53 ticks∕animal. Environmental sampling yielded 166 adult A. cajennense ticks. The tick species found on domestic animals (Rhipicephalus (Boophilus microplus, R. sanguineus, Dermacentor nitens and A. cajennense were those typically found on these hosts in Brazil. The most prevalent tick species, A. cajennense, was found on both wild and domestic animals and was also prevalent in the environment. Thus, this tick species is the primary vector that allows pathogens to bridge wild and domestic animals in the Cerrado.Neste trabalho são descritas as espécies de carrapatos de animais selvagens e domésticos e do ambiente coletados por um ano na EMBRAPA Gado de Corte localizado na área urbana de Campo Grande, Mato Grosso do Sul, Brasil.

    The seasonal distribution of Lutzomyia longipalpis was studied in two forested and five domiciliary areas of the urban area of Campo Grande; MS, from December 2003 to November 2005. Weekly captures were carried out with CDC light traps positioned on ground and in the canopy inside a residual forest and on the edge (ground) of a woodland and in at least one of the following ecotopes in peridomiciles-a cultivated area, a chicken coop, a pigsty, a kennel, a goat and sheep shelter and an intradomicile. A total of 9519 sand flies were collected, 2666 during the first year and 6853 during the second. L. longipalpis was found throughout the 2-year period, presenting smaller peaks at intervals of 2-3 months and two greater peaks, the first in February and the second in April 2005, soon after periods of heavy rain. Only In one of the woodlands was a significant negative correlation (p<0.05) between the number of insects and temperature during the first year and the climatic factors (temperature, RHA and rain) was observed. In the domiciliary areas in four domiciles some positive correlations (p< or =0.05) occurred in relation to one or more climatic factors; however, the species shows a clear tendency to greater frequency (72%) in the rainy season than in the dry (28%). Thus, we recommend an intensification of the VL control measures applied in Campo Grande, MS, during the rainy season with a view to reducing the risk of the transmission of the disease.

    This paper reports the sequence analysis of Bm86 Campo Grande strain comparing it with Bm86 and Bm95 antigens from the preparations TickGardPLUS and Gavac, respectively. The PCR product was cloned into pMOSBlue and sequenced. The secondary structure prediction tool PSIPRED was used to calculate alpha helices and beta strand contents of the predicted polypeptide. The hydrophobicity profile was calculated using the algorithms from the Hopp and Woods method, in addition to identification of potential MHC class-I binding regions in the antigens. Pair-wise alignment revealed that the similarity between Bm86 Campo Grande strain and Bm86 is 0.2% higher than that between Bm86 Campo Grande strain and Bm95 antigens. The identities were 96.5% and 96.3% respectively. Major suggestive differences in hydrophobicity were predicted among the sequences in two specific regions. PMID:18823577

    Full Text Available Determinou-se a importância epidemiológica de dípteros Fanniidae na infestação de mosca-do-berne, por meio da identificação das espécies presentes, da determinação daquelas utilizadas por Dermatobia hominis na veiculação de seus ovos, bem como, pelo conhecimento da dinâmica populacional das espécies mais abundantes. Foram utilizadas cinco armadilhas iscadas com fígado bovino cru deteriorado e colocadas em uma mata ciliar margeada por uma área de pastagem com presença constante de bovinos. O estudo foi desenvolvido em uma área da Embrapa Gado de Corte, em Campo Grande, Estado de Mato Grosso do Sul, Brasil, localizada a 20º27'S e 54º37'W. A captura dos insetos foi realizada semanalmente durante o período de 09/08/1999 a 03/08/2000. Foi capturado um total de 40.629 moscas da família Fanniidae, pertencendo a cinco espécies do gênero Fannia: F. pusio, F. heydenii, F. bahiensis e F. longipila, e uma a ser identificada. A espécie mais freqüente foi F. pusio, com 63,20% do total capturado, seguida de F. heydenii, com 28,82%. Somente 0,44% do total de fêmeas de F. heydenii (45 exemplares capturadas, principalmente nos meses de agosto e setembro, portavam ovos de D. hominis e o número médio, por indivíduo, foi de 15,98±7,13. Observaram-se ovos de D. hominis apenas na região abdominal dos vetores. F. heydenii predominou no período seco (maio a setembro e início do período chuvoso do ano (outubro e novembro. O número de exemplares portando ovos de D. hominis foi maior no final do período seco do ano, o que explica a alta incidência deste parasito em bovinos nos meses de setembro e outubro.

    Full Text Available This paper reports the sequence analysis of Bm86 Campo Grande strain comparing it with Bm86 and Bm95 antigens from the preparations TickGardPLUS and GavacTM, respectively. The PCR product was cloned into pMOSBlue and sequenced. The secondary structure prediction tool PSIPRED was used to calculate alpha helices and beta strand contents of the predicted polypeptide. The hydrophobicity profile was calculated using the algorithms from the Hopp and Woods method, in addition to identification of potential MHC class-I binding regions in the antigens. Pair-wise alignment revealed that the similarity between Bm86 Campo Grande strain and Bm86 is 0.2% higher than that between Bm86 Campo Grande strain and Bm95 antigens. The identities were 96.5% and 96.3% respectively. Major suggestive differences in hydrophobicity were predicted among the sequences in two specific regions.O objetivo deste estudo foi analisar a seqüência de Bm86 cepa Campo Grande comparando-a com os antígenos Bm86 e Bm95 das preparações TickGardPLUS e GavacTM, respectivamente.

    Full Text Available The outspread and urbanization of visceral leishmaniasis (VL in Campo Grande, state of Mato Grosso do Sul, lead us to undertake the present study over diversity and abundance of sand flies in the urban area to compare with previous search carried out during 1999/2000, before the identification of the disease in the human population.The captures were carried out with automatic light traps, weekly, from February 2004 to February 2005 on three sites including a forested area (Zé Pereira, two peridomicilies (shelters of domestic animals and cultivation areas, and intradomicilie. In the present study 110 collections were obtained during 13 months for 1320 h of collections, resulting in 5004 specimens, 3649 males and 1355 females belonging to the 20 following species: Brumptomyia avellari, Brumptomyia sp., Bichromomyia flaviscutellata, Evandromyia lenti, E. termitophila, E. cortelezzii, E. borrouli, Lutzomyia sp., L. longipalpis, Micropygomyia quinquefer, N. antunesi, N. whitmani, Pintomyia christenseni, Pi. damascenoi, Psathyromyia aragaoi, Ps. campograndensis, Ps. hermanlenti, Ps. shannoni, Pychodopygus claustrei, and Sciopemyia sordellii. L. longipalpis was the most abundant species in the anthropic environment with 92.22% of the captures. This shows an increase of sixty times in the density of L. longipalpis compared to the last sand fly evaluation in 1999/2000. The high density of L. longipalpis in Campo Grande is the main factor of risk in transmission of the disease to human in the urban area. The capture of N. antunesi, typical specie from Amazonian region, in Mato Grosso do Sul is reported for the first time.

    Full Text Available The behavior of the fresh fruits and vegetable produce section was evaluated, under the point of view of the consumer, in three types of food retail stores in Campo Grande, Brazilian southeast: a grocery store ("quitanda", a supermarket, and an open-air market. A quantitative-descriptive survey was conducted with 120 individuals, responsible for purchasing fresh fruit and vegetable produce for their homes. To accomplish that, twelve variables were investigated and adapted from the parameters used in the SERVQUAL model, in which the attributes of the retail outlet are pointed out, such as store hygiene and cleanliness and manner by which produce is displayed; employee training traits, such as courtesy and helpfulness; and quality, price range, and variety of the produce for sale. The results reveal that shopping for grocery is done weekly; 80% of the shoppers interviewed do their shopping in supermarkets and 94% do theirs in open-air markets. The open-air market had the best results in the attributes for which they were evaluated when compared with the grocery store and the supermarket. The study also points out that the older the shopper the more often he/she does grocery shopping.Neste estudo foi avaliado, sob o ponto de vista do consumidor, o desempenho da seção de hortaliças em três equipamentos varejistas de alimentos em Campo Grande(MS: uma mercearia (quitanda, um supermercado e uma feira-livre.

Os resultados mostram que as compras de hortaliças são realizadas semanalmente

  8. Coastal marsh response to rising sea levels in the Grand Bay, MS estuary

    The Grand Bay estuary, situated along the border of Alabama and Mississippi, is a marine dominant estuary. Juncus roemerianus and Spartina alterniflora cover approximately 49% of the estuary (Eleuterius and Criss, 1991); However, this marsh system is prone to erosion more than other marsh systems in the state (Mississippi Department of Marine Resources 1999). Water level and wind-driven waves are critical factors that cause erosion in the Grand Bay estuary. Sediment transport induced by wave forces from the Gulf of Mexico and sea level rise force salt marshes to migrate landward (Schmid 2000). Understanding projected variations in vegetation can aid in productive restoration planning and coastal management decisions. An integrated hydro-marsh model was developed to incorporate the dynamic interaction between tidal hydrodynamics and salt marsh system. This model projects salt marsh productivity by coupling a two-dimensional, depth-integrated ADvanced CIRCulation (ADCIRC) finite element model and a parametric marsh model (Morris et al., 2002). The model calculates marsh productivity as a function of mean low water (MLW), mean high water (MHW), and the elevation of the marsh platform. The coupling exchange process is divided into several time intervals that capture the rate of sea level rise, and update the elevation and bottom friction from the computed marsh productivity. Accurate description of salt marsh platform is necessary for calculating accurate biomass results (Hagen et al. 2013). Lidar-derived digital elevation models (DEM) over-estimate marsh platform elevations, but can be corrected with Real Time Kinematic (RTK) survey data (Medeiros et al., 2015). Using RTK data, the salt marsh platform was updated and included in a high resolution hydrodynamic model. Four projections of sea level rise (Parris et al., 2012) were used to project salt marsh productivity for the year 2100 for the Grand Bay, MS estuary. The results showed a higher productivity under low sea

    Aspects of phlebotomine behavior were investigated in the city of Campo Grande, Mato Grosso do Sul state. The insects were captured weekly during December 2003 to November 2005, with Centers for Disease Control light traps at seven different sites including forests and residential areas. In total, 11,024 specimens (7,805 males and 3,219 females) were collected, from which 9,963 (90.38%) were identified as Lutzomyia longipalpis, the proven vector of American visceral leishmaniasis agent. The remaining 9.62% comprised 21 species. L. longipalpis was the most frequent species in all sampled sites, and the first in the ranking of standardized species abundance index. In residential areas this species clearly predominated in the peridomicile (90.96%), in contrast to the intradomicile (9.04%); in animal shelters, it was more numerous in hen houses and prevailed at ground level, inside, and at forest edge around the residences; this aspect is worrying because this insect may remain sheltered in forested environments during the use of insecticides in homes. In the forest environment, other probable or proven vector of cutaneous leishmaniasis agents were also captured such as Lutzomyia whitmani (=Nyssomyia whitmani, sensu Galati), Lutzomyia antunesi (=Nyssomyia antunesi, sensu Galati), and Lutzomyia flaviscutellata (=Bichromomyia flaviscutellata, sensu Galati).

    Full Text Available Different parasites that commonly occur concomitantly can influence one another, sometimes with unpredictable effects. We evaluated pathological aspects of dogs naturally co-infected with Leishmania infantum and Ehrlichia canis. The health status of the dogs was investigated based on histopathological, hematological and biochemical analyses of 21 animals infected solely with L. infantum and 22 dogs co- infected with L. infantum and E. canis. The skin of both groups showed chronic, predominantly lymphohistioplasmacytic inflammatory reaction. The plasmacytosis in the lymphoid tissues was likely related with the hypergammaglobulinemia detected in all the dogs. The disorganization of extracellular matrix found in the reticular dermis of the inguinal region and ear, characterized by the substitution of thick collagen fibers for thin fibers, was attributed to the degree of inflammatory reaction, irrespective of the presence of parasites. In addition, the histopathological analysis revealed that twice as many dogs in the co-infected group presented Leishmania amastigotes in the ear skin than those infected solely with Leishmania, increasing the possibility of becoming infected through sand fly vectors. Our findings highlight the fact that the health of dogs infected concomitantly with L. infantum and E. canis is severely compromised due to their high levels of total plasma protein, globulins, alkaline phosphatase and creatine kinase, and severe anemia.

    Full Text Available Abundance and Distribution of Great Apes and Human Activities in the Campo Ma'an National Park, South Cameroon. The Campo Ma'an National Park (CMNP located in South Cameroon, has a rich biodiversity and is part of the priority areas of the Central Africa Network of Protected Areas. In order to improve the knowledge on great apes in this park, an inventory was conducted between October and November 2011 using the linear transect technique. In total, 103 transects, 2.5 km each, were established and surveyed. The results of the study confirm the presence of the two species of great apes in the CMNP, chimpanzees (Pan troglodytes troglodytes and gorillas (Gorilla gorilla gorilla. The inventory suggested that chimpanzees had a nest density of 0.158 nest∙km-2, allowing an estimated density of 0.555 indiv.km-2, for a total population estimated at 1466 animals weaned throughout the Park. Chimpanzees were mainly located in the northern part of the Park, near the hilly area of Niété. Gorillas had an estimated average encounter rate of 1.080 sign per km. They also appeared to be more concentrated around the area of Niété. Poaching was the preferred type of human activity in the Park and was located in the northern part of the Park. It is strongly recommended to implement the results of this study by performing regular surveys, about every 3 months, in order to monitor the demography of the great apes populations in the Park.

    Two methods using headspace solid-phase microextraction and gas chromatography-mass spectrometry were developed for the determination of polycyclic aromatic hydrocarbons (PAH) and BTEX. Best results were obtained using DVB/CAR/PDMS fiber, with 10 min extraction at 25 Degree-Sign C and 0.15 min desorption at 260 Degree-Sign C (BTEX), and PDMS/DVB fiber, with 60 min extraction at 90 Degree-Sign C, 10% NaCl and 5 min desorption at 270 Degree-Sign C (PAH). LOD intervals were 3x10{sup -2} - 5x10{sup -2} {mu}g L{sup -1} (BTEX) and 1.6x10{sup -3} - 1.4 {mu}g L{sup -1} (PAH). The methods were applied to forty-five groundwater samples from monitoring wells of gas stations and only benzene level exceeded the limit established by Brazilian regulations. (author)

    Full Text Available Pesquisas sobre deficiência visual nas populações indígenas das etnias Guarani e Kaiowá são escassas. O objetivo geral deste estudo consistiu em mapear a deficiência visual entre os escolares indígenas da Região da Grande Dourados, MS. Os objetivos específicos foram: identificar os escolares indígenas com baixa visão e cegueira nas escolas indígenas; caracterizar as causas da deficiência visual nessa população; descrever as necessidades específicas e educacionais especiais dos escolares indígenas com deficiência visual. Os procedimentos para coleta de dados foram: observação de campo e triagem ocular de seis mil escolares; avaliação oftalmológica, funcional da visão, das necessidades específicas e educacionais especiais dos escolares identificados. Os resultados indicaram alta incidência de deficiência visual entre a população estudada: nove cegos, dos quais quatro não têm acesso à educação; dos sete com baixa visão, três estão fora da escola; um deles apresenta deficiência múltipla. As causas prevalentes foram atrofia óptica e alteração retiniana. As avaliações apontam adequações relativas: distância de discriminação de objetos, gravuras, obstáculos; compensação do campo visual para locomoção e atividades diárias; adaptação de materiais pedagógicos quanto aos contrastes, tamanho de letras, cores e o controle da iluminação; necessidades de recursos ópticos especiais e não ópticos. Conclui-se que a efetivação do direito à saúde e à educação entre os escolares indígenas é ignorada pelo poder público, observa-se múltipla negação de direitos: a combinação da pobreza com a deficiência, a falta de acesso à saúde ocular e ao Atendimento Educacional Especializado.Research on visual impairment among Guarani and Kaiowá indigenous populations is scarce. The general objective of this study consisted of mapping and identifying visual impairment of indigenous students of the

Na área de campo natural detectaram-se duas unidades de vegetação principais, denominadas de unidades diferenciais A (AXONOPUS - ANDROPOGON e B (AXONOPUS - PIPTOCHAETIUM, ambas com suas respectivas subunidades de espécies possivelmente associadas. A variação espacial gradual verificada na área de campo natural configura-se principalmente pelo conjunto de condições associadas à declividade e profundidade do lençol freático. Nas áreas mineradas II e III verificou-se que as unidades de vegetação não se tinham delineado muito claramente e apresentavam características de vegetação pioneira. Na área II evidenciou-se uma possível unidade de vegetação PIPTOCHAETIUM AXONOPUSPURPUSII e na área III, PIPTOCHAETIUM - CYNODON. Verificou-se maior similaridade florística entre a área de campo natural e a área II, do que entre a III e o campo natural. As espécies presentes nas áreas mineradas apresentam certo grau de pioneirismo e tolerância em relação ao conjunto de condições extremas que enfrentam, devendo, portanto, ser as primeiras a ser testadas em trabalhos de recomposição de áreas mineradas.Studies were conducted at Mina Recreio, Butiá, RS, on floristic and phytosociological aspects in a natural grassland area laying on a coal bank and in surface coal mining areas which had beem naturally reclaimed.

    Full Text Available Questo lavoro non è un trattato sul campo geomagnetico e nemmeno
    una rassegna sull'argomento, almeno nel significato che normalmente
    si attribuisce al termine « rassegna »; esso è semplicemente
    un tentativo di condensare in termini comprensibili agli studiosi non
    specializzati ciò che oggi si sa o si ipotizza sul magnetismo terrestre
    e sulle sue cause. Chi scrive si è sempre trovato a disagio di fronte
    alle richieste di una spiegazione sull'origine del campo magnetico
    terrestre: o si cerca di cavarsela con poche parole (« si tratta di correnti
    elettriche indotte nell'interno della Terra » che possono forse accontentare
    chi non si occupa in modo particolare di problemi scientifici
    ma non possono soddisfare un fisico, oppure ci si sente obbligati a
    tentare faticosamente di approfondire, sia per capirli personalmente
    che per poterli poi spiegare agli altri, argomenti e ragionamenti che
    sono in realtà accessibili solo a un fisico teorico ben preparato. Apparentemente
    non esiste una via di mezzo, come del resto in molti altri
    campi della fisica contemporanea.
    La presente monografia rappresenta appunto il tentativo di trovare
    questa via di mezzo: nel terzo capitolo, dedicato alle teorie sull'origine
    del campo geomagnetico, si cerca di descrivere qualitativamente
    i principali processi fisici proposti come sorgenti del campo,
    dopo un accenno ai fondamenti fisici e matematici sui quali sono state
    elaborate le varie teorie. Senza farmi soverchie illusioni di essere riuscito
    nell'intento, mi dichiarerei tuttavia soddisfatto se questo lavoro
    destasse sull'argomento l'interesse di qualche giovane ricercatore, incoraggiandolo
    ad un approfondimento.

  13. Grand challenges in modeling and simulation

    2002-07-01

    Few argue with the need for modeling and simulation (M&S) to better or more completely represent current and expected military operations. The challenge is to decide where to make specific improvements in M&S representation and functionality within time, funding, technology, and research limitations. So, it is natural to select key areas - Grand Challenges - for a significant evolution in M&S where a major effort of many at considerable cost is needed to deal with the critical issues ahead. This paper selects three proposed and related Grand Challenges. First, M&S Depiction of Information and Effects-Based Operations, as a Grand Challenge, will assist in creating sufficiently realistic battlespaces for M&S users. Second, M&S Support to Crisis Response and Military Operations, as a Grand Challenge, is a key area that will help the Department of Defense meet transformation goals. Third, Effective Development of Future Simulations, as a Grand Challenge, will set the standards by which future M&S improvements and new M&S programs will be acquired to ensure needed simulations are delivered on time and at desired cost.

La estructura interna de la colada está compuesta por varias unidades de lava masiva e intercalaciones de auto brechas (con presencia de bolas de lava. El flujo Occidental está compuesto por flujos de lava de tipo escoriácea y flujos en bloques, los cuales a su vez están cubiertos de ceniza, y con un espesor inferior a 20 m, con excepción del río Reventazón, en donde posee un espesor de aproximadamente 150 m, creando a su vez el paleo-lago Cachí. Sin embargo, el flujo Occidental presenta una composición más básica (posiblemente mayor fluidez, pequeñas dimensiones, tanto en espesor como extensión, resultado de bajas tasas de efusión, pendientes altas, y/o el cese de efusión de lava. El flujo Oriental fue originado a partir de fisuras ubicadas en sitios de baja altitud, y su espesor y extensión, además de la presencia de levées, son características que permiten relacionarlo con periodos de mayor efusión o descarga.

SUBJECTS AND METHODS: Subjects were randomly included from the adult population (20 to 70 years of age of both genders (women 80%, men 20% who voluntarily agreed to participate. From the Polo Area, in the vicinity of a large petrochemical industrial complex, 409 subjects were included; from the control area (São Bernardo Campo Area 420 individuals were included. All subjects were clinically examined, and a detailed record of past thyroid illness and medications was obtained. Ultrasonographic studies were performed using a portable GE Medical Systems apparatus. Blood samples were obtained for free T4, serum TSH, and serum anti-thyroid peroxidase autoantibodies. Urine specimens were collected in Monovette syringes for assaying iodine content. Salt samples were collected at households, and the iodine content was measured. RESULTS: Chronic autoimmune thyroiditis was diagnosed both echographically (marked hypoechogenicity and immunologically (presence of autoantibodies against thyroid peroxidase. In the Polo Area, 15.6% of the examined population had chronic autoimmune thyroiditis, and in the control area (São Bernardo Campo Area, 19.5% of the population had evidence of chronic autoimmune thyroiditis (P > 0.057, not significant. The prevalence of hypothyroidism was 4.9% in the Polo Area and 8.3% in the São Bernardo Campo Area (P = 0.0461 significant.

    Full Text Available O campo da Psicologia Social é apresentado como território fértil, na contemporaneidade, para constituir-se como um laboratório para a produção em Ciências Humanas, uma vez que, no século XX, cada vez mais o social foi em direção ao psicológico. Neste campo, nosso embate dá-se no modo como entendemos o hífen pressuposto na integração psicossocial. A autora propõe que, entre o psicológico e o social, o hífen domina, pois ele é a própria essência relacional que é inerente a cada um dos elementos. Sugere que o modelo para entender o homem e suas circunstâncias proposto por Freud imbrica de forma indissociável o psicológico e o social, a ontogênese e a filogênese, com uma potência que teve impacto sobre todo o campo das Ciências Humanas. A Psicanálise é um instrumento hermenêutico para colaborar na elucidação dos fenômenos sociais. A autora utiliza imagens construídas por Freud e Walter Benjamin e poemas de Carlos Drummond de Andrade para fortalecer o entendimento do hífen psicossocial tanto em sua ação multidimensional quanto em sua organização.

    Good eyesight is often taken for granted, a situation that everyone appreciates once vision begins to fade with age. New eyeglasses or contact lenses are traditional ways to improve vision, but recent new technology, i.e. LASIK laser eye surgery, provides a new and exciting means for marked vision restoration and improvement. In mass spectrometry, detectors are the 'eyes' of the MS instrument. These 'eyes' have also been taken for granted. New detectors and new technologies are likewise needed to correct, improve, and extend ion detection and hence, our 'chemical vision'. The purpose of this report is to review and assess current MS detector technology and to provide a glimpse towards future detector technologies. It is hoped that the report will also serve to motivate interest, prompt ideas, and inspire new visions for ion detection research.

  7. Asymptotically Safe Grand Unification

    2016-01-01

    Phenomenologically appealing supersymmetric grand unified theories have large gauge representations and thus are not asymptotically free. Their ultraviolet validity is limited by the appearance of a Landau pole well before the Planck scale. One could hope that these theories save themselves, before the inclusion of gravity, by generating an interacting ultraviolet fixed point, similar to the one recently discovered in non-supersymmetric gauge-Yukawa theories. Employing a-maximization, a-theorem, unitarity bounds, as well as positivity of other central charges we nonperturbatively rule out this possibility for a broad class of prime candidates of phenomenologically relevant supersymmetric grand unified theories. We also uncover candidates passing these tests, which have either exotic matter or contain one field decoupled from the superpotential. The latter class of theories contains a model with the minimal matter content required by phenomenology.

    Terrestrial broadcast television in the United States has remained essentially unchanged in the last fifty years except for the addition of color and stereo sound. Today, personal computers are addressing the need for random access of high resolution images and CD quality audio. Furthermore, advances in digital video compression and digital communication technology have cleared the way toward offering high resolution video and audio services to consumers using traditional analog communications channels. In 1987, the U.S. Federal Communications Commission (FCC) chartered an advisory committee to recommend an advanced television system for the United States. From 1990 to 1992, the Advanced Television Test Center tested four all-digital systems, one analog High Definition Television (HDTV) system, and one enhancement NTSC system using broadcast and cable television environment simulators. The formation of the HDTV Grand Alliance in May of 1993 resulted from the withdrawal of the only analog HDTV system from the competition and a stalemate between the other four all- digital systems. The HDTV Grand Alliance system is composed of the best components from previously competing digital systems demonstrated to the FCC. Moving Pictures Experts Group (MPEG-2) syntax is used with novel encoding techniques to deliver a set of video scanning formats for a variety of applications. This paper describes the important features and concepts embodied in the HDTV Grand Alliance system.

    This paper presents a petrographical characterization of shales from Albacora, Marlim and Marlim Sul fields (offshore Campos Basin, Brazil). The characterization program included petrography analysis of thin section of undisturbed shale samples, scanning electron microscope (SEM) images and energy dispersive spectrometry (EDS) analysis. The tests were realized with the purpose of obtaining information to observe the nature of the rock microstructure. From the results presented herein, the shales can be described as silty and calciferous. The description of the thin sections indicated that all the shale samples are very similar from the compositional and textural point of view. The samples are rich in clay minerals, that show small size grains and seem homogeneous, and carbonatic cement. The samples are constituted by calcite, quartz, kaolinite, smecite, illite, illite/smectite, kaolinite/illite/smectite, feldspar, plagioclase, dolomite, chlorite and pyrite. The samples showed a great amount of calcium, resultant from the microfossils, that covers partially the clay minerals. Pyrite is also observed as small grains disperse throughout the sample with form of agglomerated pyrite framboids, cubo-octahedral and octahedral crystals. The EDS show the presence of picks of Si, Al, Mg, K and Na particles, indicating the presence of clay minerals, calcite, pyrite and chlorite. (author)

    In this study, four mixtures of LDPE post consumer with heavy gas from the Campos Basin, in different proportions, were subjected to pyrolysis in an inert atmosphere at 550 deg C. The pyrolytic liquids were characterized by gas chromatography coupled to mass spectrometry (GC/MS). Pyrolysis of pure diesel supplied large amounts of waste oil and only 4% in the range of diesel. On the other hand, the pyrolysis of LDPE mixture of diesel (at the ratio 1/0,5 m/m) provided 20% of light hydrocarbons with high production of pyrolytic oil (96%). The formation of high levels of paraffins and olefins in the range of diesel oil during the co-pyrolysis suggests a promising technology for recycling of plastic waste. (author)

    We construct a realistic model of grand unification in AdS_5 truncated by branes, in which the unified gauge symmetry is broken by boundary conditions and the electroweak scale is generated by the AdS warp factor. We show that the model preserves the successful gauge coupling unification of the 4D MSSM at leading-logarithmic level. Kaluza-Klein towers, including those of XY gauge and colored Higgs multiplets, appear at the TeV scale, while the extra dimension provides natural mechanisms for doublet-triplet splitting and proton decay suppression. In one possible scenario supersymmetry is strongly broken on the TeV brane, in which case the lightest SU(3)_C x SU(2)_L x U(1)_Y gauginos are Dirac fermions, with universal masses at the weak scale, and the mass of the lightest XY gaugino is pushed well below that of the lowest gauge boson KK mode, improving the prospects for its production at the LHC. The bulk Lagrangian possesses a symmetry that we call GUT parity. If GUT parity is exact, the lightest GUT particle,...

    The problem of visibility reduction in the Grand Canyon due to fine organic aerosol particles in the atmosphere has become an area of increased environmental concern. Aerosol particles can be derived from many emission sources. In this report, we focus on identifying organic aerosols derived from common vegetation in the Grand Canyon. These aerosols are expected to be significant contributors to the total atmospheric organic aerosol content. Aerosol samples from living vegetation were collected by resuspension of surface wax and resin components liberated from the leaves of vegetation common to areas of the Grand Canyon. The samples were analyzed using high-resolution gas chromatography/mass spectrometry (GC/MS). Probable identification of compounds was made by comparison of sample spectra with National Institute of Standards and Technology (NIST) mass spectral references and positive identification of compounds was made when possible by comparison with authentic standards as well as NIST references. Using these references, we have been able to positively identify the presence of n-alkane and n-alkanoic acid homolog series in the surface waxes of the vegetation sampled. Several monoterpenes, sesquiterpenes, and diterpenes were identified also as possible biogenic aerosols which may contribute to the total organic aerosol abundance leading to visibility reduction in the Grand Canyon.

    Seven biostratigraphic intervals have been identified through biostratigraphic studies based on calcareous nannofossils from samples of the Quaternary section of Campos and Santos basins. These intervals (named A to G) are based mainly on biological events such as extinction, first appearance, and prevalence (acme zone) of cosmopolitan taxa. In view of this, almost all recognized sections have an identity with colval biozones that have been described in the bibliography, making easier their correlation with magneto stratigraphic units and the inference of absolute ages. Nevertheless, interval D has not been consistently identified. According to what was observed it is possible to further divide the section. Such detailing would be based mainly on the appearance of Helicosphaera inversa (in interval C) and form B of H. carteri. var. wallichii (at the base of interval F), and on the abundance of H. carteri s.l. (in interval G). It is possible that other subdivisions will be delineated through quantitative investigation. However, these would be based on `anomalous` concentrations of some species with strong environmental connotation. This is the case, for example, of sharp variations in the absolute frequency of Coccolithus pelagicus which, for the time being, have been detected in intervals F and G. According to the bibliography, this species attains maximum proliferation during glacial epochs. (author). 5 figs., 1 tab.

    2010-12-01

    Giving a Grand Rounds presentation provides the hospice and palliative medicine subspecialist with the occasion to participate in a time-honored and respected event. It remains an opportunity to promote the discipline, support institutional culture change, and favorably influence the attitudes, knowledge, skills, and performance of colleagues. For those pursuing academic careers, it also is a chance to establish academic currency and develop teaching and presentation skills. In most academic settings, the format of Grand Rounds has shifted over time from a patient and problem-based discussion to a didactic, topic-focused lecture. A body of literature questions the value of this shift toward a more passive learner. Limited evidence prevents a definitive answer but many advocate for the integration of more interactive methods to improve the effectiveness of Grand Rounds. This article provides a flexible framework to guide those preparing to give a Grand Rounds and those teaching and supporting others to do so. To do this well, adult learning principles must be thoughtfully incorporated into a presentation style and method appropriate to the venue. The approach emphasizes learner-centeredness, interactive strategies, and evaluation. Room for creativity exists at every step and can add enjoyment and challenge along the way. PMID:21155643

    The KASCADE-Grande experiment, located at Karlsruhe Institute of Technology (Germany) is a multi-component extensive air-shower experiment devoted to the study of cosmic rays and their interactions at primary energies 10{sup 14}-10{sup 18} eV. Main goals of the experiment are the measurement of the all-particle energy spectrum and mass composition in the 10{sup 16}-10{sup 18} eV range by sampling charged (N{sub ch}) and muon (N{sub {mu}}) components of the air shower. The method to derive the energy spectrum and its uncertainties, as well as the implications of the obtained result, is discussed. An overview of the analyses performed by KASCADE-Grande to derive the mass composition of the measured high-energy comic rays is presented as well.

    1988-01-01

    One hundred twenty-three of 300 blood samples (41%) taken from Rio Grande wild turkeys (Meleagris gallopavo intermedia) from three locations in southern Texas (Welder Wildlife Refuge, Chaparrosa Ranch, and Campo Alegre Ranch) and subinoculated into domestic broad-breasted white turkey poults were positive for a Plasmodium (Novyella) sp. Analysis of blood films from 350 turkeys revealed Haemoproteus meleagridis in 76% of the birds. A significantly greater mean parasite intensity was observed in birds from Welder Wildlife Refuge. Birds from the Campo Alegre Ranch exhibited a significantly higher prevalence of H. meleagridis than birds from Chaparrosa. The Plasmodium sp. was infective for canaries (Serinus canaria), bobwhites (Colinus virginianus), and ring-necked pheasants (Phasianus colchicus), but would not produce infection in white leghorn chickens (Gallus gallus) or Coturnix quail (Coturnix coturnix). Attempts to infect Culex tarsalis and C. pipiens were unsuccessful. Asexual erythrocytic synchrony was not observed when blood-induced infections were monitored in two domestic turkey poults every 4 hr for 72 hr. Exoerythrocytic stages were not found upon examination of impression smears and tissue samples taken from brain, liver, spleen, kidney, lung, and bone marrow. The Plasmodium sp. is most similar morphologically to three species in the subgenus Novyella, P. hexamerium, P. vaughani, and P. kempi. The most striking similarities are to P. hexamerium, and involve mean merozoite number, erythrocytic schizont location, and vertebrate host susceptibility. It differs from P. vaughani in being able to infect turkeys and in type of parasitized erythrocytes. Differences to P. kempi include mean merozoite number, and ability to infect pheasants, and its inability to develop in C. pipiens and C. tarsalis.

  13. Helping enhances productivity in campo flicker ( Colaptes campestris) cooperative groups

    Dias, Raphael Igor; Webster, Michael S.; Macedo, Regina H.

    2015-06-01

    Reproductive adults in many bird species are assisted by non-breeding auxiliary helpers at the nest, yet the impact of auxiliaries on reproduction is variable and not always obvious. In this study, we tested Hamilton's rule and evaluated the effect of auxiliaries on productivity in the facultative cooperative breeder campo flicker ( Colaptes campestris campestris). Campo flickers have a variable mating system, with some groups having auxiliaries and others lacking them (i.e., unassisted pairs). Most auxiliaries are closely related to the breeding pair (primary auxiliaries), but some auxiliaries (secondary auxiliaries) are unrelated females that joined established groups. We found no effect of breeder quality (body condition) or territory quality (food availability) on group productivity, but the presence of auxiliaries increased the number of fledglings produced relative to unassisted pairs. Nonetheless, the indirect benefit of helping was small and did not outweigh the costs of delayed breeding and so seemed insufficient to explain the evolution of cooperative breeding in campo flickers. We concluded that some ecological constraints must limit dispersal or independent breeding, making staying in the group a "best-of-a-bad-job" situation for auxiliaries.

    El proyecto de instrumentación de mayor importancia que ha tenido el Instituto de Astrofisica de Canarias en los últimos afios ha sido el diseflo y construcción del te1escopio IAC8O. Este requería del esfuerzo con junto en mec´nica, óptica y electrónica, lo que facilitó la estructuración y el crecimiento de los respectivos grupos de trabajo, que posteriormente se integraron en departamentos En su origen (1977), el telescopio IAC80 fue concebido como un sistema clásico tipo Cassegrain, con una razón focal F/i 1.3 para el sistema Casse grain y una razón focal F/20 para el sistema Coudé. Posteriormente, aunque se mantuvo la filosofia de que el sistema básico fuera el F/11.3, se consideró conveniente el diseño de secundarios para razones focales F/16 y F/32, y se eliminó el de F/20. Sin embargo, dada la importancia relativa que un foco estrictamente fotográfico tiene en un telescopio moderno, diseñado básicamente para fotometría fotoeléctrica y con un campo util mínimamente de 40 minutos de arco, se decídió Ilevar a cabo el diseño de un secundario F/8 con un sistema corrector de campo, pero que estuviera formado únicamente por lentes con superficies esféricas para que asl su construcción fuera posible en España ó en México. La creciente utilización de detectores bidimensionales para fines de investigación astron6mica y la viabilidad de que en un futuro cercano éstos tengan un área sensible cada vez mayor, hicieron atractiva la idea de tener diseñado un sistema corrector de campo para el foco primario (F/3), con un campo útil mínimo de un grado, y también con la limitante de que sus componentes tuvieron sólamente supérficies esféricas. Ambos diseños de los sis-temas correctores de campo se llevaron a cabo, en gran medida, como parte de un proyecto de colaboración e intercambio en el área de diseño y evaluación de sistemas ópticos.

    Kojima, Kentaro; Yamashita, Toshifumi

    2011-01-01

    We propose a novel way to break grand unified gauge symmetries via the Hosotani mechanism in models that can accommodate chiral fermions. Adjoint scalar fields are realized through the so-called diagonal embedding method which is often used in the heterotic string theory. We calculate the one-loop effective potential of the adjoint scalar field in a five dimensional model compactified on an S^1/Z_2 orbifold, as an illustration. It turns out that the potential is basically the same as the one in an S^1 model, and thus the results in literatures, in addition to the chiral fermions, can be realized easily.

  2. Grand Junction Remedial Action Program

    International Nuclear Information System (INIS)

    The Grand Junction Remedial Action Program (hereinafter referred to as the Program) originated in 1972 due to a recognized need to reduce the levels of radiation found in some of the structures identified in Grand Junction, Colorado that were constructed in part with uranium mill tailings. Out of over 640 locations eventually identified as qualifying for corrective action, the Program performed remedial construction on 594 of them. The owners of over 45 unremediated structures either did not wish to participate in the voluntary Program, or the structures were torn down, burned down, or were abandoned before the Program could take action on them. Because this was the first remedial action program of its type, and because its task was to reduce the radiation levels as soon as practical, there was no time for lengthly research and development of remedial methods or techniques. Trial and error combined with basic engineering and health physics produced a Program that learned as it progressed. At a cost of $22.7 million over a 15-year period, a substantial portion of the community had radiation exposure reduced because many public buildings such as schools, churches, and businesses, as well as private residences were remediated. 21 refs., 10 figs., 6 tabs

    The petroleum systems of the Campos Basin contains 60 billion barrels of discovered oil in place and 775 billion cubic meters of natural total gas in place, comprising one of the most prolific petroleum systems in South America . It is located in southeast Brazil covering about 100,000 km{sup 2} with 44 oil fields, seven giants, holding up to 90% of total Brazilian oil reserves and 50% of total natural gas reserves. The Campos Basin produces mostly from turbiditic sandstones of the Carapebus formation (Cretaceous-Tertiary), comprising the biggest part of the total production. Other important reservoirs are calcarenites of the Macae formation (Albian), bioclastic lacustrine limestones of the Lagoa Feia formation (Barremian), and fractured basalts of the Cabiunas formation (Neocomian). The source rocks are saline-to-brackish lacustrine water of the Lagoa Feia formation (Barremian) containing 5% TOC average, an average thickness about 100 m with a maximum of 500 m in depocenters, covering approximately 50,000 km{sup 2}. Trapping style is chiefly structural for the Cabiunas formation; structural-stratigraphic for the coquinas (bioclastic limestones of the Lagoa Feia formation), where pinch-out of the coquinas is a common feature; strongly structural for the calcarenites of the Macae formation (rollovers related to salt tectonics), and finally structural combined with sandstone pinch-out for the Cretaceous and Tertiary turbidites of the Carapebus formation. At the Corvina-Parati depo center, thermal basin modeling suggests the onset of oil generation in late Albian, reaching its maximum during the Miocene and it is still going on to present days. The top of oil window is about 4,5000 m deep and transformation rate reaches up to 70%. Seismically, the Campos Basin shows distinct response and characteristics according to lithologies and ages. The lowermost sequence (Lagoa Feia and Cabiunas formations) is poor in seismic attributes; the geological model is more adequate for

    Full Text Available As organizações familiares estão presentes em todo contexto mundial, sendo micro ou pequenas empresas, são elas as responsáveis por grande parte da economia em no Brasil, elas surgem a partir de um sonho e do esforço de empreendedores que buscam construir um negócio lucrativo que dure por gerações. Entretanto, mesmo sendo tão representativas essas empresas enfrentam dificuldades durante a sucessão, que devido à falta de planejamento sucessório e da preparação dos futuros herdeiros muitas delas não chegam a segunda e a terceira geração. Com este trabalho foi possível analisarmos o processo sucessório e a importância do planejamento e da profissionalização dos sucessores. Os dados foram coletados por meio de entrevistas com base em um roteiro de perguntas semi estruturadas realizadas com os sucessores de duas pequenas empresas familiares em Campos dos Goytacazes que já passaram pelo processo sucessório. Apesar de não ter ocorrido um planejamento sucessório o fato dos sucedidos levarem seus herdeiros para a empresa quando crianças e os familiarizando ao negócio contribuiu para que a transição ocorresse sem muitos impactos dando continuidade a um empreendimento próspero.

    Full Text Available En Brasil, la idea de que la efi ciencia económica en la agricultura está directamente relacionada al tamaño de la propiedad está fuertemente incorporada. Esa herencia, al ser apropiada según las conveniencias de los grupos hegemónicos instituidos dentro de lo que se denomina de capitalismo rentista, han resultado en acciones políticas que enaltecen a la producción de commodities, sintetizadas en la expresión agronegocio, tomado como sinónimo de propiedad técnicamente moderna y con grandes dimensiones. Por consiguiente, la pequeña propiedad se tiene como reducto de la baja productividad y de la incapacidad de producir en escala compatible con las necesidades del mercado, lo que justifi caría la omisión del Estado en la recaudación de la enorme cantidad de tierras públicas invadidas, la poca relevancia de las políticas de reordenación agraria y los parcos recursos concedidos en créditos agrícolas. Sin embargo, al establecerse un recorte multiescalar en el análisis de los datos ofi ciales disponibles, particularmente los del último Censo Agropecuario, se concluye que al contrario de lo que se proclama y se ejecuta en los términos de políticas territoriales para el campo, son exactamente los pequeños establecimientos los más productivos y los que más generan empleos, a pesar de la asimetría de las políticas públicas agrícolas y la escasez de tierras a su disposición.

    The last decade has shown us that the observational properties of neutron stars are remarkably diverse. From magnetars to rotating radio transients, from radio pulsars to isolated neutron stars, from central compact objects to millisecond pulsars, observational manifestations of neutron stars are surprisingly varied, with most properties totally unpredicted. The challenge is to establish an overarching physical theory of neutron stars and their birth properties that can explain this great diversity. Here I survey the disparate neutron stars classes, describe their properties, and highlight results made possible by the Chandra X-Ray Observatory, in celebration of its 10th anniversary. Finally, I describe the current status of efforts at physical “grand unification” of this wealth of observational phenomena, and comment on possibilities for Chandra’s next decade in this field.

    Proton hexality is a discrete symmetry that avoids the problem of too fast proton decay in the supersymmetric extension of the standard model. Unfortunately it is inconsistent with conventional grand unification. We show that proton hexality can be incorporated in the scheme of ''Local Grand Unification'' discussed in the framework of model building in (heterotic) string theory. (orig.)

    As part of an NSF TUES Type 3 project entitled "Google Earth for Onsite and Distance Education (GEODE)," we are assembling a "Grand Tour" of locations on Earth and other terrestrial bodies that every geoscience student should know about and visit at least in virtual reality. Based on feedback from colleagues at previous meetings, we have identified nine Grand Tour themes: "Plates and Plumes," "Rocks and Regions," "Geology Through Time," "The Mapping Challenge*," "U.S. National Parks*," "The Magical Mystery Tour*," "Resources and Hazards," "Planets and Moons," and "Top of the Pops." Themes marked with an asterisk are most developed at this stage and will be demonstrated in real time. The Mapping Challenge invites students to trace geological contacts, measure bedding strike and dip and the plunge, trend, and facing of a fold. There is an advanced tool for modeling periclinal folds. The challenge is presented in a game-like format with an emphasis on puzzle-solving that will appeal to students regardless of gender. For the tour of U.S. national parks, we divided the most geologically important parks into four groups—Western Pacific, West Coast, Rockies, and East Coast. We are combining our own team's GigaPan imagery with imagery already available on the Internet. There is a great deal of imagery just waiting to be annotated for geological education purposes. The Magical Mystery Tour takes students to Google Streetview locations selected by instructors. Students are presented with questions or tasks and are given automatic feedback. Other themes are under development. Within each theme, we are crowd-sourcing contributions from colleagues and inviting colleagues to vote for or against proposed locations and student interactions. The GEODE team includes the authors and: Heather Almquist, Stephen Burgin, Cinzia Cervato, Gene Cooper, Paul Karabinos, Terry Pavlis, Jen Piatek, Bill Richards, Jeff Ryan, Ron Schott, Kristen St. John, and Barb Tewksbury.

  14. MS Based Metabonomics

    Energy Technology Data Exchange (ETDEWEB)

    Want, Elizabeth J.; Metz, Thomas O.

    2010-03-01

    Metabonomics is the latest and least mature of the systems biology triad, which also includes genomics and proteomics, and has its origins in the early orthomolecular medicine work pioneered by Linus Pauling and Arthur Robinson. It was defined by Nicholson and colleagues in 1999 as the quantitative measurement of perturbations in the metabolite complement of an integrated biological system in response to internal or external stimuli, and is often used today to describe many non-global types of metabolite analyses. Applications of metabonomics are extensive and include toxicology, nutrition, pharmaceutical research and development, physiological monitoring and disease diagnosis. For example, blood samples from millions of neonates are tested routinely by mass spectrometry (MS) as a diagnostic tool for inborn errors of metabolism. The metabonome encompasses a wide range of structurally diverse metabolites; therefore, no single analytical platform will be sufficient. Specialized sample preparation and detection techniques are required, and advances in NMR and MS technologies have led to enhanced metabonome coverage, which in turn demands improved data analysis approaches. The role of MS in metabonomics is still evolving as instrumentation and software becomes more sophisticated and as researchers realize the strengths and limitations of current technology. MS offers a wide dynamic range, high sensitivity, and reproducible, quantitative analysis. These attributes are essential for addressing the challenges of metabonomics, as the range of metabolite concentrations easily exceeds nine orders of magnitude in biofluids, and the diversity of molecular species ranges from simple amino and organic acids to lipids and complex carbohydrates. Additional challenges arise in generating a comprehensive metabolite profile, downstream data processing and analysis, and structural characterization of important metabolites. A typical workflow of MS-based metabonomics is shown in Figure

    Full Text Available Campo Quijano está a 30 Km. de la ciudad de Salta y cuenta aproximadamente con 8300 habitantes. En el éjido urbano existen dos borateras que constituyen una fuente puntual de contaminación del aire, suelo y aguas. Se estudió la prevalencia de enfermedades respiratorias en la población urbana en el año 2005. Se trabajó con los datos de las planillas de consultas diarias externas del Hospital Francisco Herrera. Se consideraron cuatro grupos de afecciones, seleccionados por la sintomatología y su posible asociación con las emisiones gaseosas de las borateras: Rinitis; Catarro en vías aéreas superiores, Espasmos y Tos irritativa. Se estimó y comparó la prevalencia de las enfermedades por barrio con la prueba de X2 y la de los residuales ajustados de Haberman. Los espasmos y catarros en vías aéreas superiores fueron las afecciones más frecuentes en la población de Campo Quijano. En rinitis no se encontraron diferencias entre barrios. El barrio San Roque presentó las mayores prevalencias en CVAs, espasmos y tos irritativa. Barrios cercanos a las borateras presentaron prevalencias dispares, lo que podría relacionarse con características socio-culturales, sanitarias y económicas, entre otros factores de riesgo, no considerados en este diagnóstico.

    Full Text Available El autor propone que existe una serie de creencias y prácticas tradicionales que pueden proporcionar pistas acerca de la interacción de campos electromagnéticos en la biosfera. Por ejemplo, la creencia en el mal de ojo puede ser una construcción cultural relacionada con la sensación de estar siendo observado, pero a su vez puede estar basada en las emisiones de ondas electromagnéticas a través de los ojos. En este artículo se presentan datos para apoyar esta hipótesis. Otras creencias tradicionales, como la importancia de la conexión con la Madre Tierra también pueden contener una explicación similar. En este artículo se presentan una serie de hipótesis científicamente verificables sobre creencias tradicionales y campos electromagnéticos. En esta fase, los datos son insuficientes para confirmar la hipótesis, no obstante el objetivo de este artículo es estimular el pensamiento crítico y la investigación sobre algunas creencias tradicionales.

    Full Text Available Grande parte das áreas ocupadas por pastagens no estado do Rio Grande do Sul apresentam solos ácidos que, se convenientemente corrigidos, podem ser incorporados na produção de grãos. O objetivo desta pesquisa foi avaliar a alteração de atributos químicos no perfil de um solo ácido de campo natural após receber a aplicação de calcário e ser cultivado sob diferentes manejos. Dois experimentos foram realizados: um no campo e outro em colunas de solo, em laboratório. O experimento de campo foi instalado em 1993 em área de pastagem natural nunca antes cultivada, em Latossolo Vermelho distrófico típico, no município de Cruz Alta (RS. Foram aplicadas quatro doses de calcário dolomítico (0, 2, 4 e 6 t ha-1, sem incorporação ao solo (sistema plantio direto e com incorporação (cultivo convencional. Após 42 meses de cultivo contínuo com espécies anuais (verão e inverno, amostras de solo foram coletadas em diferentes camadas no perfil do solo na área experimental e em área adjacente de campo nativo. Nesta ocasião, foram, também, coletadas colunas de PVC com amostras indeformadas de solo nas parcelas testemunhas (sem aplicação de calcário de ambos os tratamentos de manejo de solo e na área de campo nativo, adjacente.

A acurácia e a precisão no processo de semeadura são itens de grande importância para que tal sistema alcance sucesso. Sendo assim, foram selecionadas 50 propriedades e, em 38, determinou-se a profundidade de deposição da semente de milho. A área experimental era formada por quatro ou cinco linhas de semeadura, onde se avaliaram dez plântulas por linha. A profundidade ficou em torno de 46 mm, observando-se diferenças significativas entre as linhas, em 21 áreas. O coeficiente de variação médio ficou em torno de 20%, limite estatístico entre médio e alto. Conforme análise de outros parâmetros, tais coeficientes podem representar diferentes tipos de erro no processo. Pode-se considerar o processo de semeadura da região como eficiente quando considerada a média da profundidade. Entretanto, a análise da variabilidade demonstra necessidade de ações junto a fatores antrópicos e de máquina.No Tillage system is fully incorporated to farming in the region of Campos Gerais, state of Paraná. Accuracy and precision in the planting process are items of great importance for the success of this system. In order to evaluate the planting process, thirty eight farms were selected as sites for analysis of the placement depth of seeds. The research area was 4 or 5 planting rows, evaluating 10 plantlets per row. The average seed depth was around 46 mm, and significant differences between rows were observed in 21 areas. The average coefficient of variation was around 20%, the statistical limit between medium and high. Analyses of other parameters show that those coefficients may represent different errors in the process. The planting process in Campos Gerais can be considered efficient regarding to the average seed depth. However, the analysis of variability implies de need of actions concerning to anthropic and machinery factors.

    The Macae Formation (Late Albian-Turonian of the Campos Basin) is represented by a thick column of carbonate sediments whose deposition began soon after the evaporitic phase that marks the beginning of the marine occupation of the basin. The top of this interval is represented by an unconformity (Type I), indicative of a variation in the base level of the basin, on which the turbidities of the basal sequence of the Namorado Field were deposited. For a better understanding of the depositional geometry of these turbidities, the paleogeomorphology analysis demonstrated to be quite efficient. The method of work used for so was a combination among the seismic 3D visualization (VoxelGeo{sup R}), from the characterization of different physical attributes of the seismic signal, and the facies analysis of wells profiles of the referred field. The developed analysis allowed the individualization and the three-dimensional visualization of a sinuous paleochannel in the top of the interval, until then not described in previous interpretations of this depositional system. With the information coming from this study, a better understanding of the genesis of this accumulation can be reached, especially in the part regarding to the units of important economic character, represented by the turbidities deposits and whose occurrences are related with stages of relative lowering of the sea level.

    Contact aureoles rimming plutonic rocks are the locus of metamorphism and deformations witnessing magma emplacement mechanisms in the crust. In this study, structural and petrological observations are combined to mineral equilibria modelling to unravel the polyphase tectono-metamorphic history of the Permian Sondalo gabbro and its host rock, the Campo unit (Eastern Alps). The Campo unit consists of Grt-St-Ms-Bt-Pl-Qtz ± Sil ± And ± Crd mica schists attesting of a Carboniferous prograde P- T path, reaching 6 kbar/600 °C and subsequently 5.6 kbar/650 °C. This metamorphism is coeval with the formation of a sub-vertical NE-SW trending foliation (S1) and its overprint by a sub-vertical NW-SE trending foliation (S2). The heat brought by the Permian intrusives subsequently caused heating of the Campo unit at around 3-4 kbar/540 °C reflected by regional static crystallization of cordierite and andalusite porphyroblasts. During the intrusion of the Sondalo gabbro, thermal peak conditions are recorded by Grt-Sil-Spl-Crd-Ilm granulitic xenoliths at ~5.5 kbar/930 °C, subsequently exhumed at ~4 kbar during the development of a new foliation (S3). This foliation is localized around the pluton and moderately dips away from the centre of the pluton. In the migmatitic contact aureole, Grt-Sil-Bt-Pl-Qtz-Ilm and Grt-Sil-Crd-Spl-Bt-Kfs-Ilm residual rocks bear the new foliation (S3) and document a decompression from 6 kbar/750 °C to 5 kbar/725 °C and from 5.2 kbar/800 °C to reach 4.8 kbar/770 °C, respectively. The P- T- d paths recorded by the host rock and the xenoliths point to a two-step magma emplacement. First the Sondalo gabbro intruded the Campo unit causing heating of the host rock without deformation at 3-4 kbar. Second, the ductile flow along the pluton margins developed a new foliation (S3) during exhumation of the pluton and its immediate contact aureole from 6 to 4 kbar. Altogether, it indicates a progressive increase in mechanical coupling between the pluton

    RNAs have recently emerged as an exciting new target for small molecule therapeutics. Conventional HTS discovery strategies measuring disruption of RNAprotein interactions have proven unsuccessful. We describe a ligand-based drug discovery strategy that addresses the inherent difficulties RNA targets. The strategy is based on: 1) using a MS spectrometry (MS)-based assay to measure the affinity of compounds for a target; 2) performing competitive binding experiments and molecular modeling with the motifs to determine the binding site(s) of the ligands; 3) design and synthesis of derivatives of interesting binders to establish the linking sites; 4) identifying the appropriate linker group using MS; 5) fusing motifs into a more complex structure to afford higher affinity compounds. Example of applying this strategy to identify new classes of lead molecules with affinity and specificity for ribosomal RNA targets will be presented.  ……

We describe a ligand-based drug discovery strategy that addresses the inherent difficulties RNA targets. The strategy is based on: 1) using a MS spectrometry (MS)-based assay to measure the affinity of compounds for a target; 2) performing competitive binding experiments and molecular modeling with the motifs to determine the binding site(s) of the ligands; 3) design and synthesis of derivatives of interesting binders to establish the linking sites; 4) identifying the appropriate linker group using MS; 5) fusing motifs into a more complex structure to afford higher affinity compounds. Example of applying this strategy to identify new classes of lead molecules with affinity and specificity for ribosomal RNA targets will be presented.

  11. Militari italiani e grande guerra

    Full Text Available Il saggio verte su alcuni aspetti dei fenomeni immigratori che si collegano alla genesi e alla tenuta dei sensi di appartenenza etnica e nazionale. Accanto alla progressiva rimozione dei vecchi meccanismi di acculturazione linguistica, che scalzano, ove posseduto in partenza, l’italiano procurando la sua sostituzione progressiva –e in parte fisiologica– con il castigliano si assiste in America, per integrazione, anche al declino dell’“italianità politica”. Un momento di svolta prima del definitivo affermarsi di tale processo di “argentinizzazione” fu rappresentato però dalla congiuntura della grande guerra. Il suo deflagrare, infatti, coincise con il momento di massima espansione (non solo a Buenos Aires della presenza immigratoria straniera e di quella italiana in particolare. Diversamente da quanto succederà più tardi con il secondo conflitto mondiale, dopo quasi vent’anni però di declino o di arresto dei flussi in entrata, tra il 1914 e il 1918 si poté assistere infatti a una concreta forma di doppio patriottismo o di duplice lealtà politico-istituzionale da parte dei gruppi etnici immigratori all’interno dei quali si generarono scelte come la decisione presa da molti dei loro componenti di arruolarsi sotto le bandiere delle “antiche patrie” per raggiungere i campi di battaglia europei.

    Full Text Available A campilobacteriose causa um grande impacto na saúde pública em todo o mundo, sendo em muitos pa- íses a causa mais frequente de gastroenterite em humanos causada por alimentos. A principal fonte de Campylobacter são as aves, dessa forma, pode haver infecção pelo consumo de carne crua, mal cozida, contaminação cruzada no preparo dos alimentos ou por outros alimentos, como água e leite. O despreparo de muitos manipuladores de alimentos em relação a cuidados higiênicos é um dos fatores que favorece a contaminação dos alimentos, afetando principalmente ambientes como restaurantes, hospitais e indústrias de alimentos. Como o congelamento e a refrigeração têm o papel de conservar a carne em bom estado para o consumo, à detecção de bactérias viáveis nesta etapa é muito importante. Diante do exposto acima, o presente estudo teve como objetivo avaliar a ocorrência de Campylobacter spp. em frangos refrigerados comercializados na cidade de Campo Mourão-PR por meio do teste imunoenzimático pelo método ELFA (Enzime Linked Fluorescent Assay com o sistema automatizado VIDAS® campy.

    Grand Lake, located in Magadan region (51 53'E, 60 44'N), belongs to the group of Elikchan Lakes. Maximum depth of the lake is 23.2 m. 12 cores from deep and shallow parts of the lake were taken using a Livingston corer. Sediment records from Grand Lake provide a continuous archive of climate change during marine isotopic stages (MIS) 4-1. Magnetic susceptibility (MS), saturation magnetization, saturation remanence, coercive force, remanence coercivity, temperature dependence of the induced magnetization and susceptibility of sediment and magnetic extracts were analyzed. Scanning electron microscopy (SEM) with energy dispersive X-ray spectroscopy (EDX) was used to diagnose Fe-bearing minerals. MS from cores was used for correlation between the core sections. Analysis of the complex data indicate that there are four main lithologic units of sediment. Unit 1 (MIS 1), depth 0-320 cm. Upper subunit (0-150 cm) shows negative or very low MS. Sediment has high content of organic matter and SiO2 (up to 92%) because of biogenic component. The Lower subunit (depth 150-320 cm) consists of laminated organic silt. The MS of this subunit ranges from 0 to 295 (95), 10-6 SI. The sediment shows high content of Fe2O3, P2O5, MnO indicating a redox boundary. Unit 2 (MIS 2), depth 320-627 cm. Sediment is composed of laminated silt and formed during anoxic conditions. Dark thin layers are enriched with P2O5 and MnO. The unit is characterized by low MS = 57-500 (170), 10-6, SI. Vivianite and Fe-sulfides including pyrite and greigite are found in this unit. Greigite occurs in diatom valves and as fine grained aggregates and has specific thermomagnetic curves. Unit 3 (MIS 3), depth 627-965 cm. Sediment consist of homogenous silt and that accumulated during oxic conditions. Unit has highest MS in the core section: 87-1300 (480), 10-6 SI and is enriched with CaO, Na2O, K2O, SiO2. Unite 4 (MIS 4), depth-965-1015 cm includes sand, dense silt and shows high variations of MS values. According to

    Full Text Available Em muitas regiões do Brasil, tratores e implementos agrícolas têm sido usados para dar suporte aos diferentes sistemas de produção, sem uma adequação própria às condições de solo e clima. Para auxiliar os fabricantes e agricultores na solução de problemas em máquinas e implementos agrícolas, há necessidade de verificar o desempenho desses equipamentos e estabelecer condições de testes semelhantes àquelas em que estiveram sendo usados. Este trabalho teve como objetivo avaliar o desempenho de um conjunto tratorimplemento agrícola, no campo, utilizando um sistema eletrônico de medições. A potência demandada pelos equipamentos foi calculada indiretamente, com os dados de rotação do motor e consumo de combustível, nas curvas de calibração do trator. O uso de instrumentação eletrônica permitiu que se tivesse uma grande capacidade de trabalho, em razão da facilidade de programação e operação da cadeia de medições. Os resultados de campo obtidos para esforço de tração líquida indicaram tendência de comportamento similar à dos calculados por meio de fórmulas, com uma correlação de 0,996. A metodologia utilizada nos testes de desempenho operacional do conjunto trator-implemento no campo indicou ser uma ferramenta de bastante utilidade, tanto para os usuários dos equipamentos, quanto para os fabricantes.

    2012-09-01

    In the province of Chaco, Argentina, there is a very unique dispersion of metallic meteorites called ``Campo del Cielo''. One of the meteoric fragments of this dispersion, the meteorite called ``El Chaco'', consisting of 37 tons, is the second heaviest in the world. These meteorites are of great importance to the worldview of the Moqoit, aboriginal people that inhabit this region. For the local Creole population the meteorites are also relevant, that's why they have being cited in numerous documents and reports since the colonial period. During the first months of 2012, two Argentine artists and the Artistic Director of the German contemporary art exhibition called dOCUMENTA (13) tried to move ``El Chaco'' meteorite to Germany in order to exhibit it as an artistic object. Due to the fact that moving the meteorite could have a negative impact according to the Moqoit cosmology and that they were not able to participate in the decision they begun a manifestation against the movement of El Chaco. The opposition made by aboriginal communities and experts in cultural astronomy was able to stop the transfer. The whole process and its impact on the local community have promoted a deep discussion about art, science and cultural colonialism. In this paper we aim to address this debate and its consequences. This will allow us to think about contemporary forms of colonialism that are hidden in many scientific and artistic projects. Furthermore, we aim to debate about the most effective ways of protecting astronomical heritage in the Third World.

The geometrization shows that such a vector has the same geometrical structure as a gravitational Kerr field. We discuss a theoretical proposition that a rotating body generates, besides a special gravitational field, a magnetic-type gauge field which might be identified with a chiral geometrized field. This chiral field represents a novel type of field because we cannot identify it with any of the known electromagnetic fields. As an application of this theory we discuss the morphology of the planets around the sun.En este trabajo se presenta un ejemplo de una métrica especifica que geometriza explícitamente un potencial cuadrivector tipo luz (campo quiral. La geometrización muestra que tal vector tiene la misma estructura geométrica que un campo gravitacional Kerr. Se discute una proposición teórica que un cuerpo rotante genera, su gravitación y el calibre de campo tipo magnético que puede ser identificado con un campo quiral geometrizado. Este campo quiral representa un tipo novedoso de campo que no puede ser identificado con alguno de los campos electromagnéticos conocidos. Como aplicación de esta teoría se discute la morfología de los planetas alrededor del sol.

    In the northern area of Campos Basin salt gliding/spreading processes promoted the break-up and transport of Cretaceous and Tertiary rocks overlying the evaporites. This process is known as raft tectonics, and it represents the most extreme form of thin-skinned extension above the salt decollement surface. Three distinct geotectonic domains were recognized that formed in response to the raft tectonics. The first one, confined to the shallower shelf portion of the basin, is characterized by minor extension (pre-raft domain), probably because of small salt thickness and low gradient. In the second domain (or disorganized rafts domain), located in distal platformal and slope areas, seismic sections show the occurrence of blocks or rafts with angular shapes, sometimes imbricated and frequently discontinuous. In the third domain, or domain of organized rafts, located in bacinal region, seismic sections show a more continuous raft pattern, often folded because of salt compression in the distal portions of the basin. The main purposes of this work is to characterize these three tectonic domains distinguished by raft tectonics, as well as their importance in hydrocarbon accumulations in calcarenites. (author)

    There are numerous applications given to clays including oil and water adsorbent, ceramic, whitening of beverages, porcelain, waste treatment, organic carrier molecules in cosmetics and pharmaceuticals, support for catalysts. In the pharmaceutical industry, the clays are used as excipients, diluents, desiccants, emulsifiers, to mask undesirable flavors, isotonic agent such as charger and delivery of active substances. These characteristics have contributed to the expansion of the search for applications of clay minerals in the cosmetic industry. The aim of this study was to determine the elemental composition of clays from Campos Gerais, Minas Gerais, with a view to their applicability in the production of cosmetics. The elements As, Ba, Br, Ce, Cl, Co, Cr, Cs, Eu, Fe, Hf, K, La, Lu, Na, Nd, Rb, Sb, Sc, Sm, Ta, Tb, Th,U, Yb and Zn were determined by neutron activation analysis and radionuclide activity concentration of {sup 226}Ra, {sup 228} Ra, {sup 210}Pb and {sup 40}K were determined by gamma spectrometry. It was verified that the activity concentration of radionuclides was in the same concentration as the global average, indicating that these samples do not present a risk of increased radiation exposure. The concentration of most elements determined is less than or equal to the overall mean concentrations, indicated by the values of Continental Upper Crust. (author)

    Full Text Available Resumo ----- O turismo tem sido entendido por organismos internacionais como atividade com grande potencial para promover o desenvolvimento econômico e, ao mesmo tempo, que valoriza a cultura e promove a preservação das paisagens naturais. Seguindo as diretrizes internacionais, no Brasil, o turismo passou a ser entendido como uma indústria com grande potencial para gerar empregos e divisas, e se fortalece por meio da promoção da diversidade cultural, que pode estar associada às diversas culturas materiais e religiosas. Para compreender a gestão do turismo em contextos que articulam cultura, religião e desenvolvimento territorial, este ensaio teórico aponta limitações nos dois conceitos disponíveis na literatura, quais sejam, o conceito de turismo cultural e o conceito de turismo religioso, ao mesmo tempo que propõe o conceito de ‘turismo em territórios de grande densidade religiosa’, o qual incorpora o reconhecimento das dinâmicas de poder presentes nos territórios como elementos que interferem na forma como se planeja o turismo. Mobilizam-se entendimentos do campo da antropologia e da geografi a para a gestão a fim de sustentar que a discussão teórica conduzida tem um potencial explicativo para o turismo em diversas escalas territoriais, e, também, em contextos nos quais existe o diálogo entre turismo e religião. ----- Tourism in Territories of High Religious Density ----- Abstract ----- Tourism has been understood by international organizations as an activity with great potential to promote economic development, while valuing cultures and promoting the protection of natural landscapes.

  11. Energy and Mass Balance At Gran Campo Nevado, Patagonia, Chile

    Science.gov (United States)

    Schneider, C.; Kilian, R.; Casassa, G.

    The Gran Campo Nevado (GCN) Ice Cap on Peninsula Muñoz Gamero, Chile, is lo- cated in the southernmost part of the Patagonian Andes at 53S. It comprises an ice cap and numerous outlet glaciers which mostly end in proglacial lakes at sea level. The total ice covered area sums up to approximately 250 km2. GCN forms the only major ice body between the Southern Patagonian Icefield and the Street of Magallan. Its almost unique location in the zone of the all-year westerlies makes it a region of key interest in terms of glacier and climate change studies of the westwind zone of the Southern Hemisphere. Mean annual temperature of approximately +5C at sea level and high precipitation of about 8.000 mm per year lead to an extreme turn-over of ice mass from the accumulation area of the GCN Ice Cap to the ablation areas of the outlet glaciers. Since October 1999 an automated weather station (AWS) is run continuously in the area at Bahia Bahamondes for monitoring climate parameters. From February to April 2000 an additional AWS was operated on Glaciar Lengua a small outlet glacier of GCN to the north-west. Ablation has been measured at stakes during the same pe- riod. The aim of this study, was to obtain point energy and mass balance on Glaciar Lengua. The work was conducted as part of the international and interdisciplinary working group SGran Campo NevadoT and supported by the German Research Foun- & cedil;dation (DFG). Energy balance was calculated using the bulk approach formulas and calibrated to the measured ablation. It turns out, that sensible heat transfer is the major contribution to the energy balance. Since high cloud cover rates prevail, air tempera- ture is the key factor for the energy balance of the glacier. Despite high rain fall rates, energy input from rain fall is of only minor importance to the overall energy balance. From the energy balance computed, it was possible to derive summer-time degree-day factors for Glaciar Lengua. With data from the nearby

    The Albacore and Marlim giant fields are located in the province of Campos basin, about 110 km (68 mi) offshore Cape Sao Tome, in water depths ranging from 200 m (656 ft) to 2,000 m (6562 ft). The Albacora field was discovered in September 1984 by the wildcat 1-RJS-297, drilled in 293 m (961 ft) of water. Subsequently, the wildcats 1-RJS-305 and 1-RJS-342 extended the field limits to deeper waters. The Albacora field is approximately 235 km{sup 2} (90 mi{sup 2}) in area, with an estimated volume of 4.5 billion bbl of oil in place. The Marlim field was discovered in February 1985 by the wildcat 1-RJS-219A, in a water depth of 853 m (2,800 ft). The Marlim field area is about 152 km{sup 2} (58 mi{sup 2}), and the latest estimate of oil in place is about 8.2 billion bbl. The Marlim complex encompasses Marlim field itself and the surrounding proved and potential areas known as East-of-, West-of-, and South-of-Marlim, respectively. The current estimated volume of oil in place in the Marlim complex is close to 13.9 billion bbl, with a total surface of about 350 km{sup 2} (135 mi{sup 2}). Oil production in the Albacora field comes from Lower Cretaceous (Albian) and Tertiary (Eocene, Oligocene, and Miocene) turbidite reservoirs. Oligocene turbidite sandstones are the potential reservoirs in the Marlim field. These deposits are genetically associated with sea level variations and are mainly composed of massive sandstones and, subordinately, of contourites. Both fields are structurally and stratigraphically controlled accumulations. Hydrocarbons are trapped in anticlines and/or faulted blocks associated with salt tectonics. Stratigraphic contributions result from sandstone bodies pinching out against shales and marls. The development of these fields has been supported by three-dimensional seismic data. The Albacora field is being gradually put on stream from shallower to deeper waters.

    2016-04-01

    We present principal components analysis (PCA) of temporal magnetic field variations over the solar cycles 21-24. These PCs reveal two main magnetic waves with close frequencies (covering 40% of data variance) travelling from the opposite hemispheres with an increasing phase shift. Extrapolation of these PCs through their summary curve backward for 2000 years reveals a number of ~350-year grand cycles and about 2000 super-grand cycles superimposed on 22 year-cycles with the features showing a remarkable resemblance to sunspot activity reported in the past. The summary curve calculated forward for the next millennium predicts further three grand cycles with the closest grand minimum occurring in the forthcoming cycles 25-27 when the two magnetic field waves have a phase shift of 11 years. We explore a role of other independent components derived with PCA and their expected effects on the resulting summary curve, or solar activity curve. We suggest that these grand and super-grand cycles can be produced by two dynamo waves generated in different layers with close frequencies whose interaction leads to beating effects that is discussed in the work by Popova et al (2016) presented here. This approach opens a new era in investigation and prediction of solar activity on long-term timescales.

    Nowadays, in forensic laboratories, heroin profiling is frequently carried out by gas chromatography coupled with mass spectrometry (GC-MS). This analytical technique is well established, provides good sensitivity and reproducibility, and allows the use of large databases. Despite those benefits, recently introduced analytical techniques, such as ultra-high-pressure liquid chromatography (UHPLC), could offer better chromatographic performance, which needs to be considered to increase the analysis throughput for heroin profiling. With the latter, chromatographic conditions were optimized through commercial modeling software and two atmospheric pressure ionization sources were evaluated. Data obtained from UHPLC-MS/MS were thus transferred, thanks to mathematical models to mimic GC-MS data. A calibration and a validation set of representative heroin samples were selected among the database to establish a transfer methodology and assess the models' abilities to transfer using principal component analysis and hierarchical classification analysis. These abilities were evaluated by computing the frequency of successful classification of UHPLC-MS/MS data among GC-MS database. Seven mathematical models were tested to adjust UHPLC-MS/MS data to GC-MS data. A simplified mathematical model was finally selected and offered a frequency of successful transfer equal to 95%.

    Compound identification from accurate mass MS/MS spectra is a bottleneck for untargeted metabolomics. In this study, we propose nine rules of hydrogen rearrangement (HR) during bond cleavages in low-energy collision-induced dissociation (CID). These rules are based on the classic even-electron rule and cover heteroatoms and multistage fragmentation. We evaluated our HR rules by the statistics of MassBank MS/MS spectra in addition to enthalpy calculations, yielding three levels of computational MS/MS annotation: "resolved" (regular HR behavior following HR rules), "semiresolved" (irregular HR behavior), and "formula-assigned" (lacking structure assignment). With this nomenclature, 78.4% of a total of 18506 MS/MS fragment ions in the MassBank database and 84.8% of a total of 36370 MS/MS fragment ions in the GNPS database were (semi-) resolved by predicted bond cleavages. We also introduce the MS-FINDER software for structure elucidation. Molecular formulas of precursor ions are determined from accurate mass, isotope ratio, and product ion information. All isomer structures of the predicted formula are retrieved from metabolome databases, and MS/MS fragmentations are predicted in silico. The structures are ranked by a combined weighting score considering bond dissociation energies, mass accuracies, fragment linkages, and, most importantly, nine HR rules. The program was validated by its ability to correctly calculate molecular formulas with 98.0% accuracy for 5063 MassBank MS/MS records and to yield the correct structural isomer with 82.1% accuracy within the top-3 candidates. In a test with 936 manually identified spectra from an untargeted HILIC-QTOF MS data set of human plasma, formulas were correctly predicted in 90.4% of the cases, and the correct isomer structure was retrieved at 80.4% probability within the top-3 candidates, including for compounds that were absent in mass spectral libraries.

  14. The Grand Tack model: a critical review

    CERN Document Server

    Raymond, Sean N

    2014-01-01

    The `Grand Tack' model proposes that the inner Solar System was sculpted by the giant planets' orbital migration in the gaseous protoplanetary disk. Jupiter first migrated inward then Jupiter and Saturn migrated back outward together. If Jupiter's turnaround or "tack" point was at ~1.5 AU the inner disk of terrestrial building blocks would have been truncated at ~1 AU, naturally producing the terrestrial planets' masses and spacing. During the gas giants' migration the asteroid belt is severely depleted but repopulated by distinct planetesimal reservoirs that can be associated with the present-day S and C types. The giant planets' orbits are consistent with the later evolution of the outer Solar System. Here we confront common criticisms of the Grand Tack model. We show that some uncertainties remain regarding the Tack mechanism itself; the most critical unknown is the timing and rate of gas accretion onto Saturn and Jupiter. Current isotopic and compositional measurements of Solar System bodies -- including ...

  20. Raptor Use of the Rio Grande Gorge

    Energy Technology Data Exchange (ETDEWEB)

    Ponton, David A. [Los Alamos National Lab. (LANL), Los Alamos, NM (United States)

    2015-03-20

    The Rio Grande Gorge is a 115 km long river canyon located in Southern Colorado (15 km) and Northern New Mexico (100 km). The majority of the canyon is under the administration of the Bureau of Land Management {BLM), and 77 km of the canyon south of the Colorado/New Mexico border are designated Wild River under the National Wild and Scenic Rivers Act of 1968. Visits I have made to the Rio Grande Gorge over the past 15 .years disclosed some raptor utilization. As the Snake River Birds of Prey Natural Area gained publicity, its similarity to the Rio Grande Gorge became obvious, and I was intrigued by the possibility of a high raptor nesting density in the Gorge. A survey in 1979 of 20 km of the northern end of the canyon revealed a moderately high density of red-tailed hawks and prairie falcons. With the encouragement of that partial survey, and a need to assess the impact of river-running on nesting birds of prey, I made a more comprehensive survey in 1980. The results of my surveys, along with those of a 1978 helicopter survey by the BLM, are presented in this report, as well as general characterization of the area, winter use by raptors, and an assessment of factors influencing the raptor population.

    This study describes the validation and application of two independent analytical methods for the determination of glyphosate in breast milk. They are based on liquid chromatography-tandem mass spectrometry (LC-MS/MS) and gas chromatography-tandem mass spectrometry (GC-MS/MS), respectively. For LC-MS/MS, sample preparation involved an ultrafiltration followed by chromatography on an anion exchange column. The analysis by GC-MS/MS involved an extraction step, cleanup on a cation exchange column, and derivatization with heptafluorobutanol and trifluoroacetic acid anhydride. Both methods were newly developed for breast milk and are able to quantify glyphosate residues at concentrations as low as 1 ng/mL. The methods were applied to quantify glyphosate levels in 114 breast milk samples, which had been collected from August to September of 2015 in Germany. The mothers participated at their own request and thus do not form a representative sample. In none of the investigated samples were glyphosate residues above the limit of detection found.

  6. Hematozoan parasites of Rio Grande wild turkeys from southern Texas (USA)

    Science.gov (United States)

    Castle, Marc D.; Christensen, Beth A.; Rocke, Tonie E.

    1988-01-01

    One hundred twenty-three of 300 blood samples (41%) taken from Rio Grande wild turkeys (Meleagris gallopavo intermedia) from three locations in southern Texas (Welder Wildlife Refuge, Chaparrosa Ranch, and Campo Alegre Ranch) and subinoculated into domestic broad-breasted white turkey poults were positive for a Plasmodium (Novyella) sp. Analysis of blood films from 350 turkeys revealed Haemoproteus meleagridis in 76% of the birds. A significantly greater mean parasite intensity was observed in birds from Welder Wildlife Refuge. Birds from the Campo Alegre Ranch exhibited a significantly higher prevalence of H. meleagridis than birds from Chaparrosa. The Plasmodium sp. was infective for canaries (Serinus canaria), bobwhites (Colinus virginianus), and ring-necked pheasants (Phasianus colchicus), but would not produce infection in white leghorn chickens (Gallus gallus) or Coturnix quail (Coturnix coturnix). Attempts to infect Culex tarsalis and C. pipiens pipiens were unsuccessful. Asexual erythrocytic synchrony was not observed when blood-induced infections were monitored in two domestic turkey poults every 4 hr for 72 hr. Exoerythrocytic stages were not found upon examination of impression smears and tissue samples taken from brain, liver, spleen, kidney, lung, and bone marrow. The Plasmodium sp. is most similar morphologically to three species in the subgenus Novyella, P. hexamerium, P. vaughani, and P. kempi. The most striking similarities are to P. hexamerium, and involve mean merozoite number, erythrocytic schizont location, and vertebrate host susceptibility. It differs from P. vaughani in being able to infect turkeys and in type of parasitized erythrocytes. Differences to P. kempi include mean merozoite number, and ability to infect pheasants, and its inability to develop inC. pipiens and C. tarsalis.

    In the 1960s and 1970s numerous bridges were built in the US with a design similar to those on Interstate 40 (I-40) over the Rio Grande in Albuquerque, New Mexico. The Federal Highway Administration (FHWA) and the National Science Foundation (NSF) have provided funds to New Mexico State University (NMSU) through the New Mexico State Highway and Transportation Department (NMSH and TD) and The Alliance For Transportation Research (ATR) for evaluation and testing of the existing fracture-critical bridges over the Rio Grande. Because the I-40 Bridges over the Rio Grande were to be razed during the summer of 1993, the investigators were able to introduce damage into the structure in order to test various damage identification methods and to observe the changes in load paths through the structure caused by the cracking. To support this research effort, NMSU contracted Los Alamos National Laboratory (LANL) to perform experimental modal analyses, and to develop experimentally verified numerical models of the bridge. A previous report (LA-12767-MS) summarizes the results of the experimental modal analyses. This report summarizes the numerical analyses of the bridges and compares the results of these analyses to the experimental results.

    Full Text Available As leguminosas forrageiras, além de contribuírem para o aumento da oferta de forragem com alto teor de proteína, também são importantes como cobertura vegetal de solos. Entre as leguminosas com grande potencial forrageiro, espécies do gênero Lotus têm se destacado. Este trabalho visou à seleção de rizóbios nativos eficientes em Lotus glaber a partir de amostras de solo de cinco localidades do Rio Grande do Sul. Obtiveram-se 259 isolados de rizóbios, que foram avaliados quanto à morfologia colonial e produção de melanina. Destes, 15 isolados foram selecionados para avaliação da eficiência na fixação simbiótica de nitrogênio em experimento em casa de vegetação e caracterizados geneticamente por comparação do perfil eletroforético dos produtos de amplificação do DNA genômico, por PCR com os oligonucleotídeos iniciadores BOX e ERIC. Apenas cinco isolados produziram melanina. Nove isolados foram mais eficientes do que a estirpe SEMIA 830, que é autorizada para a produção de inoculante para L. glaber no país. Na caracterização genética, observou-se que nenhum isolado apresentou identidade com as estirpes recomendadas, o que demonstra que, nos solos do Rio Grande do Sul, existem rizóbios autóctones eficientes na fixação simbiótica de nitrogênio com L. glaber, podendo ser recomendados para estudos a campo, visando a uma futura produção de inoculantes para estas leguminosas no Brasil.Forage legumes besides contributing to increase the supply of high protein content forage are also good cover for the soil surface. Among the legumes with high potential forage, the genus Lotus has been outstanding. This research aimed to selectnative rhizobia efficient in fixing nitrogen with Lotus glaber, from soil samples of five localities of Rio Grande do Sul. A total of 259 rhizobia isolates were obtained, which were evaluated based on colony morphology and in vitro melanin production. Among them, 15 isolates were selected

  5. Actual stage of organic geochemical knowledge from Campos and Espirito Santo basins, Brazil

    International Nuclear Information System (INIS)

    Campos and Espirito Santo basins display several similar geochemical aspects. The microbial and other degradation processes caused changes in the composition of the oils in the reservoir rocks. The oils are biodegraded in different degrees, with the reservoir temperature developing an important role in the control of the biodegradation process. The migration pathway model is similar for Campos and Espirito Santo basins, involving the upward secondary migration through a window in the evaporitic seals. The oils passed to the marine sequence where migration and accumulation were controlled by faults, regional unconformities and by reservoirs. The geochemical correlation of oils are realized by gaseous and liquid chromatography analysis, carbon isotopes and biolabelled compounds. (author)

  9. Qualitative identification of rodenticide anticoagulants by LC-MS/MS.

    Middleberg, Robert A; Homan, Joseph

    2012-01-01

    Rodenticide anticoagulants are used in the control of rodent populations. In addition to accidental ingestions in humans, such agents have also been used for homicidal and suicidal purposes. There are two major groups of rodenticide anticoagulants - hydroxycoumarins and indanediones. Before the advent of LC-MS/MS, analysis for such agents was relegated to such techniques as TLC and HPLC with nonspecific modes of detection. LC-MS/MS has been used to determine any given number of rodenticide anticoagulants in animal tissues, foods, plasma, etc. Use of this technique allows for the simultaneous identification of individual compounds within both classes of rodenticide anticoagulants. The LC-MS/MS method presented allows for simultaneous qualitative identification of brodifacoum, bromadiolone, chlorphacinone, dicumarol, difenacoum, diphacinone, and warfarin in blood, serum, and plasma using ESI in the negative mode. Two transitions are monitored for each analyte after a simple sample preparation. Chromatographic separation is accomplished using a gradient of ammonium hydroxide in water and ammonium hydroxide in methanol. Chloro-warfarin is used as internal standard. PMID:22767114

  11. Inflationary Reheating in Grand Unified Theories

    Bassett, B A; Bassett, Bruce A.; Tamburini, Fabrizio

    1998-01-01

    Grand unified theories may display multiply interacting fields with strong coupling dynamics. This poses two new problems: (1) What is the nature of chaotic reheating after inflation, and (2) How is reheating sensitive to the mass spectrum of these theories ? We answer these questions in two interesting limiting cases and demonstrate an increased efficiency of reheating which strongly enhances non-thermal topological defect formation, including monopoles and domain walls. Nevertheless, the large fluctuations may resolve this monopole problem via a modified Dvali-Liu-Vachaspati mechanism in which non-thermal destabilsation of discrete symmetries occurs at reheating.

    @@ The Kyoto Protocol was taken into effect on Feb. 16, 2005. It requires developed countries to reduce their greenhouse gas emissions, but it doesn't set binding limits on developing countries, such as China. The developed countries found that it is more cost-effective to reduce the emissions in developing countries than in their own. Therefore, the CDM emerged as the times require. Due to unfamiliarity and complicatedness, Chinese enterprises had been hesitating and taking wait-and-see attitude toward CDM, but they couldn't resist the attraction of free dinner of CDM, more and more enterprises started to attend the grand banquet of CDM since 2006.

    7 pages Galileo noted in the 16th century that the period of oscillation of a pendulum is almost independent of the amplitude. However, such a pendulum is damped by air friction. The latter may be viewed as resulting from air molecules getting in contact with the pendulum. It follows that air friction, not only damps the oscillation, but also introduces randomness. In the so-called ``grand-mother'' clock, discovered by Huygens in the 18th century, damping is compensated for, on the average...

  15. The periodicity of Grand Solar Minimum

    Science.gov (United States)

    Velasco Herrera, Victor Manuel

    2016-07-01

    The sunspot number is the most used index to quantify the solar activity. Nevertheless, the sunspot is a syn- thetic index and not a physical index. Therefore, we should be careful to use the sunspot number to quantify the low (high) solar activity. One of the major problems of using sunspot to quantify solar activity is that its minimum value is zero. This zero value hinders the reconstruction of the solar cycle during the Maunder minimum. All solar indexes can be used as analog signals, which can be easily converted into digital signals. In con- trast, the conversion of a digital signal into an analog signal is not in general a simple task. The sunspot number during the Maunder minimum can be studied as a digital signal of the solar activity In 1894, Maunder published a discovery that has maintained the Solar Physics in an impasse. In his fa- mous work on "A Prolonged Sunspot Minimum" Maunder wrote: "The sequence of maximum and minimum has, in fact, been unfailing during the present century [..] and yet there [..], the ordinary solar cycle was once interrupted, and one long period of almost unbroken quiescence prevailed". The search of new historical Grand solar minima has been one of the most important questions in Solar Physics. However, the possibility of estimating a new Grand solar minimum is even more valuable. Since solar activity is the result of electromagnetic processes; we propose to employ the power to quantify solar activity: this is a fundamental physics concept in electrodynamics. Total Solar Irradiance is the primary energy source of the Earth's climate system and therefore its variations can contribute to natural climate change. In this work, we propose to consider the fluctuations in the power of the Total Solar Irradiance as a physical measure of the energy released by the solar dynamo, which contributes to understanding the nature of "profound solar magnetic field in calm". Using a new reconstruction of the Total Solar Irradiance we found the

    Full Text Available A presença de infecções na corrente sanguínea representa uma grave complicação na situação de pacientes críticos, podendo aumentar os riscos de morbidade e mortalidade, sendo a hemocultura um importante recurso no diagnóstico do agente microbiano. Entre as bactérias causadoras de bacteriemia, encontramos, frequentemente, a Acinetobacter spp, sendo um patógeno de grande importância clínica devido ao aumento de sua frequência como causa de infecções hospitalares e, também, por, normalmente, apresentar multirresistência aos agentes antimicrobianos de prática clínica. O presente estudo teve como finalidade o levantamento epidemiológico de infecções em hemoculturas causadas pelo gênero Acinetobacter spp em pacientes internados, em hospitais de São José dos Campos-SP, demonstrando sua prevalência no munícipio. Os dados analisados foram fornecidos pelo sistema de um laboratório de análises microbiológicas e utilizados para o levantamento de infecções por Acinetobacter spp em hemoculturas, no período de agosto de 2012 a agosto de 2013. Foram avaliados 5.759 exames de hemocultura, com 1.019 resultados positivos, sendo que Acinetobacter baumannii foi identificada em 31 amostras, correspondendo ao sexto patógeno mais isolado (3,04% das hemoculturas positivas. A. baumannii se tornou um patógeno de grande preocupação hospitalar, devido à sua crescente colonização nas Unidades de Tratamento Intensivo e sua multirresistência aos antimicrobianos.

    Full Text Available Este artigo tem por objetivo descrever as condições socioeconômicas e ambientais das comunidades rurais do campo petrolífero Canto do Amaro, estado do Rio Grande do Norte. Os procedimentos metodológicos utilizados foram: realização de pré-teste; aplicação de questionário pelo método de survey e análise estatística descritiva pelo software SPSS. Constatou-se que, apesar da importância da região analisada, a população encontra-se em um cenário de grandes restrições socioeconômicas. Observou-se, também, uma acentuada deficiência dos componentes de saneamento ambiental das comunidades rurais investigadas. Com base na percepção ambiental dos moradores questionados verificou-se que os principais problemas da localidade são: deficiência no abastecimento de água; falta de coleta de lixo; inexistência de esgotamento sanitário; poluição sonora; desmatamento; desperdício de água; desemprego; violência; ausência de pavimentação; falta de escola; iluminação pública e energia elétrica precária. Portanto, torna-se necessário e imprescindível investir no desenvolvimento sustentável e includente para evitar uma sociedade futura de anomia e valores enfraquecidos.

    Full Text Available A doença de Alzheimer é uma enfermidade neurodegenerativa, progressiva e irreversível, de aparecimento insidioso, e com a evolução da doença seu portador perde a autonomia e precisa de um cuidador que lhe dedique total atenção. Diante deste contexto, este trabalho objetivou descrever e compreender como ocorre a reconfiguração de campo do familiar cuidador responsável pelo portador de Alzheimer. Para tanto, realizou-se uma pesquisa qualitativa, pautada na perspectiva fenomenológica e na teoria de campo, fundamento teórico da abordagem Gestáltica, e utilizou-se o método de Amedeo Giorgi. O estudo desenvolveu-se com três cuidadoras familiares de pacientes portadores de Alzheimer diagnosticados havia mais de seis meses. Encontraram-se quatro categorias que descrevem a reconfiguração do campo das cuidadoras: Assumindo a responsabilidade em cuidar; Mudanças na família; Rede de apoio social; e Estratégias de enfrentamento. Concluiu-se que o processo de reconfiguração do campo do familiar cuidador é longo e passa por diversas reestruturações dinâmicas e estruturais.

    2012-01-01

    A brief review is given of recent developments related to the Higgs signal and its implications for supersymmetry in the supergravity grand unification framework. The Higgs data indicates that the allowed parameter space largely lies on focal curves and focal surfaces of the Hyperbolic Branch of radiative breaking of the electroweak symmetry where TeV size scalars naturally arise. The high mass of the Higgs leads to a more precise prediction for the allowed range of the spin independent neutralino -proton cross section which is encouraging for the detection of dark matter in future experiments with greater sensitivity. Also discussed is the status of grand unification and a natural solution to breaking the GUT group at one scale and resolving the doublet-triplet problem. It is shown that the cosmic coincidence can be compatible within a supersymmetric framework in a muticomponent dark matter picture with one component charged under $B-L$ while the other component is the conventional supersymmetric dark matter...

  16. Elastoplasticidad anisotropa de metales en grandes deformaciones

    Caminero Torija, Miguel Angel

    El objetivo de este trabajo es el desarrollo de modelos y algoritmos numericos que simulen el comportamiento del material bajo estas condiciones en el contexto de programas de elementos finitos, dando como resultado predicciones mas precisas de los procesos de conformado y deformacion plastica en general. Para lograr este objetivo se han desarrollado diversas tareas destinadas a mejorar las predicciones en tres aspectos fundamentales. El primer aspecto consiste en la mejora de la descripcion del endurecimiento cinematico anisotropo en pequenas deformaciones, lo cual se ha realizado a traves de modelos y algoritmos implicitos de superficies multiples. Ha sido estudiada la consistencia de este tipo de modelos tanto si estan basados en una regla implicita similar a la de Mroz o en la regla de Prager. Ademas se han simulado los ensayos de Lamba y Sidebottom, obteniendo, en contra de la creencia general, muy buenas predicciones con la regla de Prager. Dichos modelos podrian ser extendidos de forma relativamente facil para considerar grandes deformaciones a traves de procedimientos en deformaciones logaritmicas, similares a los desarrollados en esta tesis y detallados a continuacion. El segundo aspecto consiste en la descripcion de la anisotropia elastoplastica inicial. Esto se ha conseguido mediante el desarrollo de modelos y algoritmos para plasticidad anisotropa en grandes deformaciones, bien ignorando la posible anisotropia elastica, bien considerandola simultaneamente con la anisotropia plastica. Para ello ha sido necesario desarrollar primero un nuevo algoritmo de elastoplasticidad anisotropa en pequenas deformaciones consistentemente linealizado y sin despreciar ningun termino, de tal forma que se conserve la convergencia cuadratica de los metodos de Newton. Este algoritmo en pequenas deformaciones ha servido para realizar la correccion plastica de dos algoritmos en grandes deformaciones. El primero de estos algoritmos es una variacion del clasico algoritmo de

    Full Text Available É crescente a disponibilidade e utilização de campos de chuva estimados por sensoriamento remoto ou calculados por modelos de circulação da atmosfera, os quais são freqüentemente utilizados como entrada para modelos hidrológicos distribuídos. A distribuição espacial dos campos de chuva estimados é altamente relevante e deve ser avaliada frente aos campos de chuva observados. Este artigo propõe um método de comparação espaço-temporal entre campos de chuva observados e estimados baseado na comparação pixel a pixel e na construção de tabelas de contingência. Duas abordagens são utilizadas: (i a análise integrada no espaço gera índices de performance que retratam a qualidade do campo de chuva estimada em reproduzir a ocorrência de chuva observada ao longo do tempo; (ii a análise integrada no tempo produz mapas dos índices de performance que resumem a destreza das estimativas de ocorrência de chuva em cada pixel. Como exemplo de aplicação, é analisada a chuva estimada na climatologia do modelo global de circulação da atmosfera CPTEC/COLA sobre a bacia do Rio Grande. Utilizando-se cinco índices de performance, o método proposto permitiu identificar variações sazonais e padrões espaciais na performance das estimativas de chuva em relação a campos de chuva derivados de observações em pluviômetros.There is an increasing availability and application of precipitation fields estimated by remote sensing or calculated by atmospheric circulation models, which are frequently used as input for distributed hydrological models. The spatial distribution of the estimated precipitation fields is extremely important and must be verified against observed precipitation fields. This paper proposes a method for spatiotemporal comparison between observed and estimated precipitation fields based on a pixel by pixel comparison and on contingency tables. Two distinct approaches are carried out: (i the spatial integrated analysis

    Full Text Available Os desenvolvimentos recentes no campo da biologia molecular abrem novas perspectivas para o estudo, diagnóstico e terapêutica das grandes endemias que afetam sobretudo as nações em desenvolvimento. As técnicas de manipulação de genes permitem a expressão de antígenos de patógenos em larga escala, com a potencial utilização como reagentes para diagnóstico ou imunógenos. Adicionalmente, essas técnicas poderão levar à obtenção de novas vacinas vivas atenuadas. Por outro lado, a determinação da seqüência dos genomas de patógenos poderá levar a novos alvos para o desenho racional de drogas com potencial quimioterápico. Entretanto, esses avanços só estarão à disposição dos países em desenvolvimento se houver um programa contínuo de investimento e de formação e valorização de recursos humanos competentes nessas novas tecnologias.

    Full Text Available En este artículo se investiga la dinámica territorial de la frontera agrícola brasileña en la región centro-norte del país. Se trata de un espacio de modernización agropecuaria reciente que adquirió en las últimas décadas nuevas dinámicas territoriales por cuenta de un significativo aumento de la producción de mercancías primarias, industriales, comerciales y de servicios. Estos cambios son observados en el campo y en la ciudad, e indican que la frontera agrícola brasileña adquiere nuevos contenidos espaciales, económicos y demográficos, que se derivan de la presencia de los agricultores modernos, de las grandes empresas y de los trabajadores. Las contradicciones que han surgido también son significativas, ya que este proceso beneficia solo a algunos sectores de la sociedad, lo que genera diferentes tipos de conflictos.

  4. La masa de los grandes impactores

    Science.gov (United States)

    Parisi, M. G.; Brunini, A.

    Los planetas han sido formados fundamentalmente acretando masa a través de colisiones con planetesimales sólidos. La masa más grande de la distribución de planetesimales y las masas máxima y mínima de los impactores, han sido calculadas usando los valores actuales del período y de la inclinación de los planetas (Lissauer & Safronov 1991; Parisi & Brunini 1996). Recientes investigaciones han mostrado, que las órbitas de los planetas gigantes no han sufrido variaciones con el tiempo, siendo su movimiento regular durante su evolución a partir de la finalización de la etapa de acreción (Laskar 1990, 1994). Por lo tanto, la eccentricidad actual de los planetas gigantes se puede utilizar para imponer una cota máxima a las masas y velocidades orbitales de los grandes impactores. Mediante un simple modelo dinámico, y considerando lo arriba mencionado, obtenemos la cota superior para la masa del planetesimal más grande que impactó a cada planeta gigante al final de su etapa de acreción. El resultado más importante de este trabajo es la estimación de la masa máxima permitida para impactar a Júpiter, la cúal es ~ 1.136 × 10 -1, siendo en el caso de Neptuno ~ 3.99 × 10 -2 (expresada en unidades de la masa final de cada planeta). Además, fue posible obtener la velocidad orbital máxima permitida para los impactores como una función de su masa, para cada planeta. Las cotas obtenidas para la masa y velocidad de los impactores de Saturno y Urano (en unidades de la masa y velocidad final de cada planeta respectivamente) son casi las mismas que las obtenidas para Júpiter debido a que estos tres planetas poseen similar eccentricidad actual. Nuestros resultados están en buen acuerdo con los obtenidos por Lissauer & Safronov (1991). Estas cotas podrían ser utilizadas para obtener la distribución de planetesimales en el Sistema Solar primitivo.

    Four-dimensional Higgs field is identified with the extra-dimensional component of gauge potentials in the gauge-Higgs unification scenario. SO(5) × U(1) gauge-Higgs EW unification in the Randall-Sundrum warped space is successful at low energies. The Higgs field appears as an Aharonov-Bohm phase 𝜃H in the fifth dimension. Its mass is generated at the quantum level and is finite. The model yields almost the same phenomenology as the standard model for 𝜃H bosons around 6-10 TeV with very broad widths. The scenario is generalized to SO(11) gauge-Higgs grand unification. Fermions are introduced in the spinor and vector representations of SO(11). Proton decay is naturally forbidden.

    A Unified Grand Tour of Theoretical Physics invites its readers to a guided exploration of the theoretical ideas that shape our contemporary understanding of the physical world at the fundamental level. Its central themes, comprising space-time geometry and the general relativistic account of gravity, quantum field theory and the gauge theories of fundamental forces, and statistical mechanics and the theory of phase transitions, are developed in explicit mathematical detail, with an emphasis on conceptual understanding. Straightforward treatments of the standard models of particle physics and cosmology are supplemented with introductory accounts of more speculative theories, including supersymmetry and string theory. This third edition of the Tour includes a new chapter on quantum gravity, focusing on the approach known as Loop Quantum Gravity, while new sections provide extended discussions of topics that have become prominent in recent years, such as the Higgs boson, massive neutrinos, cosmological perturba...

    4D Higgs field is identified with the extra-dimensional component of gauge potentials in the gauge-Higgs unification scenario. $SO(5) \\times U(1)$ gauge-Higgs EW unification in the Randall-Sundrum warped space is successful at low energies. The Higgs field appears as an Aharonov-Bohm phase $\\theta_H$ in the fifth dimension. Its mass is generated at the quantum level and is finite. The model yields almost the same phenomenology as the standard model for $\\theta_H < 0.1$, and predicts $Z'$ bosons around 6 - 10 TeV with very broad widths. The scenario is genelarized to $SO(11)$ gauge-Higgs grand unification. Fermions are introduced in the spinor and vector representations of $SO(11)$. Proton decay is naturally forbidden.

  9. Prospects of solving grand challenge problems

    Gupta, R

    1995-01-01

    The recent woes of the supercomputer industry and changes in federal funding have caused some scientists to re-evaluate the means by which they hope to solve Grand Challenge problems. I evaluate the potential of Massively Parallel Processors (MPP) within this context and the state of today's MPP. I stress that for solving large-scale problems MPP are crucial and that it is essential to seek a balance between CPU performance, memory access time, inter-node communications, and I/O. To achieve this it is important to preserve certain characteristics of the hardware while selecting the hottest processor to design the machine around. I emphasize that for long term stability and growth of parallel computing priority should be given to standardizing software so that the same code can run on different platforms and on machines ranging from clusters of workstations to MPP.

    The low energy effective action of string theory depends strongly on the process of compactification and the localization of fields in extra dimensions. Explicit string constructions towards the minimal supersymmetric standard model (MSSM) reveal interesting results leading to the concept of local grand unification. Properties of the MSSM indicate that we might live at a special location close to an orbifold fixed point rather than a generic point in Calabi-Yau moduli space. We observe an enhancement of (discrete) symmetries that have various implications for the properties of the MSSM such as proton stability as well as solutions to the flavor problem, the m-problem and the strong CP-problem.

After a short introduction to each of these disciplines in isolation, we identify a series of burning questions and grand challenges associated with their continuing development and integration. We then discuss potential pathways towards solving these challenges, grouped by strategical, technical, and collaborative developments.

  14. Preface to a GUT (Grand Unified Theory)

    International Nuclear Information System (INIS)

    A Grand Unified Theory (GUT) is proposed exhibiting relativistic invariance and based on a physical model for vacuum space consisting of the superposition of oppositely charged continuous fluids. Models for the photon, electron, neutrino, proton, etc., consist of separate unique variations in the relative densities of the fluids and their flow patterns. This GUT is also based on the use of transfinite axiomatic number forms and on a concept of metrical relativity which hopefully reconciles the many logical dichotomies in and between Special Relativity and Quantum Mechanics. These ideas result in a number of experimental proposals and predicted results which appear to be underivable from present paradigms, first among which is a physical model for the hidden variable of Quantum Mechanics. It is on these features that attention should rest. (Auth.)

    We compute the effective action for stationary and spatially constant magnetic fields, when coupled anomalously to charge neutral fermions, by integrating out the fermions. From this the grand canonical partition function and potential of the fermions and fields are computed. This also takes care of magnetic field dependent vacuum corrections to the grand canonical potential. Possible applications to neutron stars are indicated.

    El objetivo de este trabajo es el desarrollo de modelos y algoritmos numericos que simulen el comportamiento del material bajo estas condiciones en el contexto de programas de elementos finitos, dando como resultado predicciones mas precisas de los procesos de conformado y deformacion plastica en general. Para lograr este objetivo se han desarrollado diversas tareas destinadas a mejorar las predicciones en tres aspectos fundamentales. El primer aspecto consiste en la mejora de la descripcion del endurecimiento cinematico anisotropo en pequenas deformaciones, lo cual se ha realizado a traves de modelos y algoritmos implicitos de superficies multiples. Ha sido estudiada la consistencia de este tipo de modelos tanto si estan basados en una regla implicita similar a la de Mroz o en la regla de Prager. Ademas se han simulado los ensayos de Lamba y Sidebottom, obteniendo, en contra de la creencia general, muy buenas predicciones con la regla de Prager. Dichos modelos podrian ser extendidos de forma relativamente facil para considerar grandes deformaciones a traves de procedimientos en deformaciones logaritmicas, similares a los desarrollados en esta tesis y detallados a continuacion. El segundo aspecto consiste en la descripcion de la anisotropia elastoplastica inicial. Esto se ha conseguido mediante el desarrollo de modelos y algoritmos para plasticidad anisotropa en grandes deformaciones, bien ignorando la posible anisotropia elastica, bien considerandola simultaneamente con la anisotropia plastica. Para ello ha sido necesario desarrollar primero un nuevo algoritmo de elastoplasticidad anisotropa en pequenas deformaciones consistentemente linealizado y sin despreciar ningun termino, de tal forma que se conserve la convergencia cuadratica de los metodos de Newton. Este algoritmo en pequenas deformaciones ha servido para realizar la correccion plastica de dos algoritmos en grandes deformaciones.

    New SHRIMP radiogenic isotope dating on zircons in tuffs (280.8 ± 1.9 Ma) confirms the Early Permian (Artinskian) age of the uppermost section of the Tunas Formation. Tuff-rich levels in the Tunas Formation are exposed in the Ventana foldbelt of central Argentina; they are part of a deltaic to fluvial section corresponding to the late overfilled stage of the Late Paleozoic Sauce Grande foreland basin. Recent SHRIMP dating of zircons from the basal Choiyoi volcanics exposed in western Argentina yielded an age of 281.4 ± 2.5 Ma (Rocha-Campos et al., 2011). The new data for the Tunas tuffs suggest that the volcanism present in the Sauce Grande basin can be considered as the distal equivalent of the earliest episodes of the Choiyoi volcanism of western Argentina. From the palaeoclimatic viewpoint the new Tunas SHRIMP age confirms that by early Artinskian glacial conditions ceased in the Sauce Grande basin and, probably, in adajacent basins in western Gondwana.

    2016-01-01

    This report provides an overview of the Parallel Grand Canonical Monte Carlo (ParaGrandMC) simulation code. This is a highly scalable parallel FORTRAN code for simulating the thermodynamic evolution of metal alloy systems at the atomic level, and predicting the thermodynamic state, phase diagram, chemical composition and mechanical properties. The code is designed to simulate multi-component alloy systems, predict solid-state phase transformations such as austenite-martensite transformations, precipitate formation, recrystallization, capillary effects at interfaces, surface absorption, etc., which can aid the design of novel metallic alloys. While the software is mainly tailored for modeling metal alloys, it can also be used for other types of solid-state systems, and to some degree for liquid or gaseous systems, including multiphase systems forming solid-liquid-gas interfaces.

    Full Text Available Este artigo apresenta um sistema de suporte à decisão para a otimização de alternativas de desenvolvimento de campos de petróleo. O desenvolvimento de um campo de petróleo consiste na escolha de uma alternativa para a explotação de um reservatório petrolífero, conhecido e delimitado, que permita produzir a maior quantidade de hidrocarboneto possível, dentro dos limites físicos e econômicos existentes, isto é, maximizar o valor presente líquido (VPL. O VPL é calculado a partir da produção de óleo, a qual é obtida com o uso de um simulador de reservatório. Cada execução do simulador pode demorar desde alguns segundos até várias horas, dependendo da complexidade do reservatório modelado. Isto reduz o número de alternativas que podem ser geradas e avaliadas pelo especialista na busca da melhor solução. Deste modo, o objetivo deste trabalho é propor e avaliar um sistema inteligente de otimização que emprega: algoritmos genéticos (AGs, algoritmos culturais (ACs e coevolução para a busca de uma alternativa de desenvolvimento ótima; e um ambiente de computação paralela para a simulação de reservatório e cálculo do VPL das alternativas. O sistema resultante permite que o especialista obtenha, em tempo hábil, a alternativa ótima (ou quase-ótima para o desenvolvimento de um campo de petróleo conhecido. Os resultados obtidos nos estudos de casos apresentados demonstram que o sistema proposto, baseado em técnicas inteligentes, obtém boas alternativas de desenvolvimento de campos petrolíferos com uma grande redução do tempo computacional, redução esta obtida a partir do aproveitamento do poder computacional de um ambiente de computação paralela e do aproveitamento de conhecimento do especialista, por meio das sementes iniciais.This paper presents an optimization system for the development of petroleum fields.

    Full Text Available En presente trabajo hemos tratado el rol de los campos fantasmas en el proceso de renormalización del formalismo Lagrangiano perturbativo para un modelo t-J. Mostramos que con la incorporación de campos fantasmas apropiados en los propagadores y vértices de la teoría, la misma puede ser renormalizada a todo orden. Esto se pone en evidencia en el estudio detallado de la renormalización del propagador ferromagnético del magnón, mostrando el ablandamiento térmico de la frecuencia. También hemos analizado el caso antiferromagnético, y estos resultados fueron confrontados con estudios previos en teorías del "spin-polarón".

    Full Text Available Campos rupestres are rare and endangered ecosystems that accommodate a species-rich flora with a high degree of endemism. Here, we make available a dataset from phytosociological surveys carried out in the Itacolomi State Park, Minas Gerais, southeastern Brazil. All species in a total of 30 plots of 10 x 10 m from two study sites were sampled. Their cardinality, a combination of cover and abundance, was estimated. Altogether, we registered occurrences from 161 different taxa from 114 genera and 47 families. The families with the most species were Poaceae and Asteraceae, followed by Cyperaceae. Abiotic descriptions, including soil properties such as type, acidity, nutrient or aluminum availability, cation exchange capacity, and saturation of bases, as well as the percentage of rocky outcrops and the mean inclination for each plot, are given. This dataset provides unique insights into the campo rupestre vegetation, its specific environment and the distribution of its diversity.

    Full Text Available ABSTRACTWe studied the effects of seed storage on germination and dormancy alleviation in three species of Fabaceae endemic to campo rupestrein southeastern Brazil. Fresh seeds of Collaea cipoensis, Mimosa maguirei and Mimosa foliolosawere set to germinate and germination of seeds after four, five and 13 years of storage was tested. Seed viability was maintained for all species after the full storage period. Seed storage significantly increased germination percentage and decreased germination time for C. cipoensisand M. foliolosa, suggesting the alleviation of physical dormancy with storage. However, we did not find evidence of dormancy alleviation in M. maguirei since stored seeds showed a decrease in germination in comparison to that of fresh seeds. Our data indicate species-specific storage-mediated dormancy alleviation, which will have important implications for restoration of campo rupestre.

    International Nuclear Information System (INIS)

    Radiometric determination methods, such as alpha spectrometry require long counting times when low activities are to be determined. Mass spectrometric techniques as Inductively Coupled Plasma Mass Spectrometry (ICP-MS), Thermal Ionisation Mass Spectrometry (TIMS) and Accelerator Mass Spectrometry (AMS) have shown several advantages compared to traditional methods when measuring long-lived radionuclides. Mass spectrometric methods for determination of very low concentrations of elemental isotopes, and thereby isotopic ratios, have been developed using a variety of ion sources. Although primarily applied to the determination of the lighter stable element isotopes and radioactive isotopes in geological studies, the techniques can equally well be applied to the measurement of activity concentrations of long-lived low-level radionuclides in various samples using 'isotope dilution' methods such as those applied in inductively coupled plasma mass spectrometry (ICP-MS). Due to the low specific activity of long-lived radionuclides, many of these are more conveniently detected using mass spectrometric techniques. Mass spectrometry also enables the individual determination of Pu-239 and Pu-240, which cannot be obtained by alpha spectrometry. Inductively Coupled Plasma Mass Spectrometry (ICP-MS) are rapidly growing techniques for the ultra-trace analytical determination of stable and long-lived isotopes and have a wide potential within environmental science, including ecosystem tracers and radio ecological studies. Such instrumentation, of course needs good radiochemical separation, to give best performance. The objectives of the project is to identify current needs and problems within low-level determination of long-lived radioisotopes by ICP-MS, to perform intercalibration and development and improvement of ICP-MS methods for the measurement of radionuclides and isotope ratios and to develop new methods based on modified separation chemistry applied to new auxiliary

El objetivo de esta investigación es demostrar la pertinencia del supuesto teórico darwinista de selección natural en la discriminación de belleza escénica de la figura del bailarín en el sistema piramidal de selección, formación y desempeño profesional del campo cubano del ballet. El campo del ballet se registra fácticamente en instituciones culturales pobladas por individuos que persiguen cotidianamente crear bailarines profesionales aptos -primera condición es ser revolucionario- que representen internacionalmente a la Revolución Cubana. El campo se estructura en un sistema piramidal de selección, formación y desempeño de bailarines profesionales que rige sus prácticas principales de exclusión/inclusión -puntos de corte- por el principio darwinista de selección natural. Los exámenes de capacidades físicas de ingreso y pase de nivel a la enseñanza de nivel medio y la aceptación a la compañía profesional Ballet Nacional de Cuba conforman los puntos de corte del sistema piramidal. Estos contienen prácticas sociales que valoran -empírica, pero sistemáticamente- las características morfo-funcionales de los participantes interesados respecto al deber ser del canon artístico de figura, para seleccionar siempre a los más bellos, los más aptos, bailarines de ballet.

    2012-01-01

    Tamoxifen is a selective estrogen receptor modulator (SERM) that is used widely in the treatment of estrogen receptor positive breast cancer (ER+). Therapeutic monitoring of tamoxifen, and its metabolites N-desmethyltamoxifen (NDTam) and 4-hydroxy-N-desmethyltamoxifen (endoxifen), may be clinically useful for guiding treatment decisions. Two significant barriers to tamoxifen efficacy are: (1) variability in conversion of tamoxifen into the potent antiestrogenic metabolite, endoxifen, and (2) poor compliance and adherence to tamoxifen therapy. Therapeutic monitoring can be used to address both of these issues. Low levels of endoxifen indicate either poor compliance or poor metabolism of tamoxifen. Low tamoxifen levels would suggest poor compliance while a low ratio of endoxifen to NDTam would be indicative of poor metabolism. Solid phase extraction of patient serum followed by liquid chromatography tandem mass spectrometry (LC-MS/MS) detection enables rapid, accurate, detection of tamoxifen, N-desmethyltamoxifen, and endoxifen.

    An important task for the forensic toxicologist and expert witness is the detection of the noxa in biological matrices. Because of this, the identification and quantification of residues of illegal drugs in human hair is still of growing interest. Utilizing the advantages of GC/MS/MS testing human hair is performed for most common drugs of abuse like heroin and other opioides, cocaine, cannabis and amphetamine derivatives. Analyzing hair specimens for substances that present a toxicological risk is another challenge. Several quality control parameters must be observed to avoid false positive or false negative results and to gain additional information. Blank sample, blank hair as well as the combined wash extracts are tested for the presence of the relevant compounds within every series. Careful evaluation of the findings can provide an approximate measure of the intensity of drug use in the majority of cases.

Corell, Arctic Climate Impact Assessment team (ACIA), "If you want to see what will happen in the rest of the world 25 years from now just look what's happening in the Arctic," (Arctic Council meeting, Iceland, 08/03). What to do? Make abrupt Arctic climate change a grand challenge for the IPY-4 and beyond! Scientifically:Describe the "state" of the Arctic climate system as succinctly as possible and accept it as the point of departure.Develop a hypothesis and criteria what constitutes "abrupt climate change," in the Arctic that can be tested with observations. Observations: Bring to bear existing observations and coordinate new investments in observations through an IPY-4 scientific management committee. Make the new Barrow, Alaska, Global Climate Change Research Facility a major U.S. contribution and focal point for the IPY-4 in the U.S Arctic. Arctic populations, Native peoples: The people of the North are living already, daily, with wrenching change, encroaching on their habitats and cultures. For them "the earth is faster now," (I. Krupnik and D. Jolly, ARCUS, 2002). From a political, economic, social and entirely realistic perspective, an Arctic grand challenge without the total integration of the Native peoples in this effort cannot succeed. Therefore: Communications must be established, and the respective Native entities must be approached with the determination to create well founded, well functioning, enduring partnerships. In the U.S. Arctic, Barrow with its long history of involvement and active support of science and with the new global climate change research facility should be the focal point of choice Private industry: Resource extraction in the Arctic followed by oil and gas consumption, return the combustion

    2015-01-01

    Different clinical types of algae-related poisoning have attracted scientific and commercial attention: paralytic shellfish poisoning (PSP), diarrhetic shellfish poisoning (DSP), and amnesic shellfish poisoning (ASP). Bioassays are common methods for the determination of marine biotoxins. However, biological tests are not completely satisfactory, mainly due to the low sensitivity and the absence of specialized variations. In this context LC-MS methods replaced HPLC methods with optical detectors, allowing both effective seafood control and monitoring of phytoplankton in terms of the different groups of marine biotoxins. This chapter describes state-of-the-art LC-MS/MS methods for the detection and quantitation of different classes of phycotoxins in shellfish matrices. These classes include the highly hydrophilic paralytic shellfish poisoning (PSP) toxins. Hydrophilic interaction liquid chromatography (HILIC) has been shown to be useful in the separation of PSP toxins and is described in detail within this chapter. Another important class of phycotoxins is diarrhetic shellfish poisoning (DSP) toxins. This group traditionally comprises okadaic acid and dinophysistoxins (DTXs), pectenotoxins (PTXs), and yessotoxins (YTXs). The most recently described shellfish poisoning syndrome, azaspiracid shellfish poisoning (AZP) is caused by azaspiracids, which in turn are diarrhetic, but usually are treated separately as AZP. The last group of regulated shellfish toxins is the amnesic shellfish poisoning (ASP) toxin domoic acid, produced by species of the genus Pseudo-nitzschia.

    Full Text Available O trabalho avaliou a separabilidade de classes de água, a partir de técnicas de análises da reflectância de superfície, com dados medidos em campo e imagens multiespectrais adquiridas em nível orbital. A área de estudo foi o reservatório Rodolfo Costa e Silva, localizado na região central do Rio Grande do Sul. A metodologia foi baseada na coleta de dados in situ – total de sólidos em suspensão, clorofila (a, b, c, transparência da água e espectros de reflectância bidirecional – em 21 pontos amostrais no dia 16 de maio de 2006. A técnica de remoção do contínuo foi aplicada aos espectros de campo em quatro intervalos de bandas de absorção: 400-550nm, 610-640nm, 650-680nm e 580-700nm. Os parâmetros de remoção do contínuo das bandas de absorção analisados foram: profundidade, área e largura. Verificou-se que os parâmetros de profundidade, área e a largura da banda de absorção não apresentaram potencial de separabilidade em classes espectrais relacionadas à pequena variação na concentração dos componentes opticamente ativos na água. Imagens CBERS-2/CCD e Landsat 5/TM adquiridas em datas próximas à atividade de campo foram corrigidas dos efeitos atmosféricos e classificadas. Os resultados das classificações não apresentaram correlações significativas com os parâmetros de qualidade da água, a fim de proporcionar uma caracterização espectral das classes de água ou compartimentos. A dificuldade no estabelecimento de relações entre os parâmetros de reflectância espectral e qualidade da água foi devida, principalmente, à baixa variabilidade dos componentes opticamente ativos na água do Reservatório Rodolfo Costa e Silva. Neste caso, as análises espectrais testadas neste trabalho não foram sensíveis às pequenas variações observadas por meio dos dados de campo.

  3. A unified grand tour of theoretical physics

    Griffiths, J

    2002-01-01

    Anyone offering a grand tour is faced with several options. Should they concentrate on what may be considered to be essential features, or should they attempt to present a brief glimpse of almost everything? The present offering is a compromise between these two extremes. The area considered - theoretical physics - is now such a vast subject that some kind of compromise is essential. Indeed, the field is now so wide that few could even attempt to review it in a single-authored work. My task here is to assess how well this book has succeeded in its main aim of providing a unified (though introductory) tour of this subject. Constrained within a single volume, this is clearly not an updated Landau-Lifschitz. It cannot be expected to take any particular topic to the level of recent research. Nevertheless, it does seem to cover the broad range of essential topics which now constitute the subject. It starts (most appropriately in my opinion) with geometry. It then covers classical physics, general relativity and qu...

    2016-09-01

    The SO(11) gauge-Higgs grand unification in the Randall-Sundrum warped space is presented. The 4D Higgs field is identified as the zero mode of the fifth-dimensional component of the gauge potentials, or as the fluctuation mode of the Aharonov-Bohm phase θ along the fifth dimension. Fermions are introduced in the bulk in the spinor and vector representations of SO(11). SO(11) is broken to SO(4)×SO(6) by the orbifold boundary conditions, which is broken to SU2×U1×SU3 by a brane scalar. Evaluating the effective potential V(θ), we show that the electroweak symmetry is dynamically broken to U1. The quark-lepton masses are generated by the Hosotani mechanism and brane interactions, with which the observed mass spectrum is reproduced. Proton decay is forbidden thanks to the new fermion number conservation. It is pointed out that there appear light exotic fermions. The Higgs boson mass is determined with the quark-lepton masses given; however, it turns out to be smaller than the observed value.

    The global-scale dynamo action achieved in a simulation of a Sun-like star rotating at thrice the solar rate is assessed. The 3-D MHD Anelastic Spherical Harmonic (ASH) code, augmented with a viscosity minimization scheme, is employed to capture convection and dynamo processes in this G-type star. The simulation is carried out in a spherical shell that encompasses 3.8 density scale heights of the solar convection zone. It is found that dynamo action with a high degree of time variation occurs, with many periodic polarity reversals occurring roughly every 6.2 years. The magnetic energy also rises and falls with a regular period. The magnetic energy cycles arise from a Lorentz-force feedback on the differential rotation, whereas the processes leading to polarity reversals are more complex, appearing to arise from the interaction of convection with the mean toroidal fields. Moreover, an equatorial migration of toroidal field is found, which is linked to the changing differential rotation, and potentially to a nonlinear dynamo wave. This simulation also enters a grand minimum lasting roughly 20 years, after which the dynamo recovers its regular polarity cycles.

  8. Local grand unification in the heterotic landscape

    Energy Technology Data Exchange (ETDEWEB)

    Schmidt, Jonas

    2009-07-15

    We consider the possibility that the unification of the electroweak interactions and the strong force arises from string theory, at energies significantly lower than the string scale. As a tool, an effective grand unified field theory in six dimensions is derived from an anisotropic orbifold compactification of the heterotic string. It is explicitly shown that all anomalies cancel in the model, though anomalous Abelian gauge symmetries are present locally at the boundary singularities. In the supersymmetric vacuum additional interactions arise from higher-dimensional operators. We develop methods that relate the couplings of the effective theory to the location of the vacuum, and find that unbroken discrete symmetries play an important role for the phenomenology of orbifold models. An efficient algorithm for the calculation of the superpotential to arbitrary order is developed, based on symmetry arguments. We furthermore present a correspondence between bulk fields of the orbifold model in six dimensions, and the moduli fields that arise from compactifying four internal dimensions on a manifold with non-trivial gauge background.

  9. The grand descent has begun for CMS

    CERN Multimedia

    2006-01-01

    Until recently, the CMS experimental cavern looked relatively empty; its detector was assembled entirely at ground level, to be lowered underground in 15 sections. On 2 November, the first hadronic forward calorimeter led the way with a grand descent. The first section of the CMS detector (centre of photo) arriving from the vertical shaft, viewed from the cavern floor. There is something unusual about the construction of the CMS detector. Instead of being built in the experimental cavern, like all the other detectors in the LHC experiments, it was constructed at ground level. This was to allow for easy access during the assembly of the detector and to minimise the size of the excavated cavern. The slightly nerve-wracking task of lowering it safely into the cavern in separate sections came after the complete detector was successfully tested with a magnetic field at ground level. In the early morning of 2 November, the first section of the CMS detector began its eagerly awaited descent into the underground ca...

    This article focus on an innovative project launched by PETROBRAS with the main purpose of minimizing the impacts of drilling activities in Campos Basin, over the fishery industry in the northeast region of Rio de Janeiro. This project is seen as a relevant part of PETROBRAS' corporate social responsibility actions. In this sense, it is supposed to consider the interests of all parts directly and indirectly related and affected by the companies' intervention. The major conclusion is that the project could be an important first step to restructure the fishery sector an to harmonize the 'sea users'. A potential improvement could be the promotion of a more effective participation of fishermen in the project and the inclusion of the social and environmental dimensions. (author)

    A simple and high-throughput screening method for the analysis of 136 pesticides in avocado ( Persea americana ) by LC-(+)-ESI-MS/MS and GC-MS/MS is presented. A modified QuEChERS sample preparation method was developed to improve the extraction recovery of highly lipophilic pesticides. Extracts from minced avocados after acetonitrile (MeCN) extraction were directly injected to LC-MS/MS, whereas other GC-amenable compounds were treated with the modified QuEChERS procedure for GC-MS/MS analysis. The average recoveries for 79 pesticides quantified by LC-MS/MS at 10, 50, and 200 ng/g fortifying levels were 86.1% or better (with maximum RSD at 9.2%), whereas GC-MS/MS analysis demonstrated 70.2% or better (RSD < 18%) for average recovery from 57 compounds at the same spike levels. The application of LC- and GC-MS/MS combined with the improved extraction procedures led to the current method, which can quantitate these pesticides even if they are present in avocados below the targeted action level by FDA. This method demonstrated the improved recovery of several challenging lipophilic pesticides in highly fat-rich avocados. PMID:23362971

    An integrated paleoecological, biostratigraphic and cyclostratigraphic study was carried out on sedimentary rhythm sequences in the Oligocene-Miocene of the Campos Basin, Brazil. The bio stratigraphic data combined with the spectral analysis performed on numerical data based on carbonate content variations of cores from well A, Campos Basin, reveal a periodicity related to the Milankovitch cycles. Benthic foraminiferal biofacies oscillations recognized in these cores have the same frequency and phase of long eccentricity cycles (400 Ka). Paleoceanographic changes (such as changes in ocean currents, water temperature and food supply) can modify the distribution and frequency patterns of foraminifera assemblages. However, the method used to interpret the biofacies, the geological context of the studied area and the proposed genetic model to explain the origin of these rhythmically patterned rocks, suggest that changes in foraminiferal biofacies are directly related to the paleobathymetry variations induced by glacio-eustatic oscillations of relative sea level . According to the proposed model, productivity-dilution cycles were instrumental in the origin of these marl-limestone couplets. During regressive phases, conditions were established to increase continental runoff to a bathyal setting. The increase of continental runoff with decrease of contribution of the main carbonate components led to the deposition of marlstone. During the transgressive phase, the relative reduction in clay input from continental sediments, favored a productivity growth of pelagic carbonate (calcareous nannofossil and planktonic foraminifera), which created conditions facilitating the deposition of limestone layers. The paleobathymetry oscillations, interpreted from the benthic foraminifera assemblage, and the formation of couplets, seems to be in phase with the transgressive-regressive cycles indicating a common cause to both processes.

La metodología para el tratamiento de los datos consistió en la conversión de los valores azimutales (variables circulares a datos numéricos mediante los senos directores con el fi n de evitar incompatibilidades en la medida del error. El análisis geoestadístico mostró que la variabilidad espacial de los datos son concurrentes con un efecto pepita de 0.0017 más un modelo exponencial con meseta igual a 0.0087 y rango de infl uencia de 7874 pies. La dirección del AEMH, estimada por el método de kriging ordinario de bloques, indicó que los valores AEMH varían entre 11º-65º, con un valor promedio de 34º, mientrasque el error de estimación varía entre 2° y 7°. Los resultados obtenidos permitieron diferenciar dos campos de orientación de esfuerzos mínimos horizontales: uno al norte, donde el AEMH tiende a valores inferiores a 40º y representan el 75% de los datos estimados; mientras que el 25% de los datos restantes, superan los valores obtenidos en el norte, debido probablemente a una mayor complejidad estructural de la zona.

OBJETIVOS: Avaliar clínica, epidemiológica e laboratorialmente pacientes com Leishmaniose Tegumentar Americana , atendidos no Hospital Universitário Maria Aparecida Pedrossian, Universidade Federal de Mato Grosso do Sul, Brasil (HU/UFMS. MÉTODOS: Trata-se de um estudo observacional do tipo transversal com abordagem descritiva e analítica. Foram avaliados, retrospectivamente, dados de pacientes suspeitos de Leishmaniose Tegumentar Americana , atendidos no HU/UFMS de 1998 a 2008, e encaminhados ao Laboratório de Parasitologia/UFMS para complementação diagnóstica. Para a inclusão neste estudo foram considerados critérios clínicos e laboratoriais. RESULTADOS: Quarenta e sete pacientes foram incluídos no estudo. Houve predominância de homens de 45 a 59 anos, com a forma cutânea, lesão única, ulcerada, em áreas expostas do corpo e com duração menor que seis meses. O comprometimento de mucosas foi crescente com o aumento da idade e maior em pacientes que procuraram atendimento tardiamente. Intradermorreação de Montenegro foi o exame de maior sensibilidade e o encontro do parasito mostrou-se mais difícil em lesões antigas. CONCLUSÃO: Suspeição diagnóstica precoce é de extrema importância para diagnóstico preciso. Associação de exame parasitológico e imunológico torna mais seguro o diagnóstico laboratorial.BACKGROUND: American cutaneous leishmaniasis is a disease with a wide variety of clinical manifestations that is expanding throughout Brazil, the state of Mato Grosso do Sul constituting a significant endemic area. OBJECTIVES: To evaluate the clinical, epidemiological and laboratory characteristics of patients with American cutaneous leishmaniasis. Patients were recruited among those attending the Maria Aparecida Pedrossian Teaching Hospital of the Federal University of Mato Grosso do Sul, Brazil. METHODS: This was a cross-sectional, observational study conducted using a descriptive and analytical approach. Data from patients suspected of having American cutaneous leishmaniasis who were receiving care at this institute between 1998 and 2008 and were referred to the institute's parasitology laboratory for confirmation of diagnosis were evaluated retrospectively. Clinical and laboratory criteria were taken into consideration for the inclusion of patients to the study. RESULTS: Forty-seven patients were included in the study, the majority of whom were male and between 45 and 59 years of age. Most had the cutaneous form of the disease with a single, ulcerated lesion on exposed areas of the body, which had generally been present for periods of less than six months. Mucosal involvement increased with age and was highest in patients who had sought medical care at a later stage. The Montenegro skin test showed the highest sensitivity. Finding the parasite was more difficult in older lesions. CONCLUSION: Suspicion of the disease at an early stage is of extreme importance for a precise diagnosis. A combination of parasitological and immunological tests renders laboratory diagnosis more reliable.

    Many observables seen in intermediate energy heavy-ion collisions can be explained on the basis of statistical equilibrium. Calculations based on statistical equilibrium can be implemented in microcanonical ensemble, canonical ensemble or grand canonical ensemble. This paper deals with calculations with canonical and grand canonical ensembles. A recursive relation developed recently allows calculations with arbitrary precision for many nuclear problems. Calculations are done to study the nature of phase transition in nuclear matter.

    1978-03-01

    Full Text Available This article analyzes the different building stages of three large sea platforms. After studying the structure's main characteristics, preparing scale models and calculating ail the elements, platform construction was carried out in three stages: — Dry-dock construction of the hull base. — Installation in the water and finishing the structure. — Immersion and bridge installation. Finally, the necessary operations to move the platform to its definite location were carried out. The structures are formed by a parallelepiped hull of reinforced concrete, divided into compartments by means of vertical orthogonals panels on top of which 2 or 4 piles are placed to support the bridge.

    En este artículo se analizan las diversas etapas en la realización de tres grandes plataformas marinas. Después de un estudio de las características principales de la estructura, ensayos en modelo reducido y cálculo de todos los elementos, se procede a la construcción de las plataformas en tres fases: — Construcción en seco de la base del casco. — Colocación en el agua y acabado de la estructura. — Inmersión y colocación del puente. Por último, se realizan las operaciones necesarias para llevar la plataforma a su ubicación definitiva. Las estructuras están formadas por un casco paralelepipédico de hormigón armado, dividido en compartimientos mediante tabiques verticales ortogonales y sobre el que se han colocado 2 ó 4 pilas que soportan el puente.

  11. Observational Needs from the WCRP Grand Challenges

    2016-07-01

    An innovative history of platforms and instruments has provided remarkable satellite-based views of and data about our planet over roughly the past 35 years. The fragile and temporary nature of these satellite systems remind us that, from a climate viewpoint, we have not in any way solved or completed our observational tasks. Instead, the challenges of using satellites to observe key features of our planet's climate grow more complicated and the need grows more urgent. Admitting that we have borrowed and adopted some of our current capabilities from meteorological satellites, we need continuity of what we have as well as innovation and extension to reach new features that we now recognise as important. The scientific goals of the WCRP Grand Challenges emphasise this simultaneous need for continuation and innovation. We need longer better records of global changes in cloud types and distributions but we also need sharp accurate views of water vapour beneath those clouds. We need gravity missions to continue to track the net mass losses from Greenland and Antarctica while at the same time we need innovative remote sensing techniques to quantify rapid ice discharges at their peripheries. We need longer and broader latitudinal records of precipitation, snow cover and soil moisture but we also crucially need to detect hydrological and biogeochemical processes at the root zone. We must maintain continuity and consistency of ocean surface temperature, surface salinity and surface wind records while we also develop new methods to reveal and record deep ocean temperatures and currents. For immediate scientific, economic and political reasons we must develop a comprehensive CO2 monitoring system. And we need open high-quality access to all these data to understand present and preceding conditions as we encounter the surprises of the Anthropocene.

    Biancardi, Alberto; Dall'Asta, Chiara

    2015-01-01

    An LC-MS/MS method is proposed for the analysis of sterigmatocystin in cereals and feed. The method is based on a solid-liquid extraction and a dilute-and-shoot approach. Accuracy and precision were established at the LOQ (1 μg kg(-1)); the mean overall recovery (n = 6) was 98%, with a confidence interval of 3.8% and a CV% of 3.7%. Accuracy and precision were also assessed at three other concentration levels (2.03, 5.07 and 10.14 μg kg(-1); six replicates per level). The mean overall recovery (n = 24, LOQ included) was 99% with a confidence interval of 0.8% and a CV% of 1.9%. The method was then applied to 14 naturally incurred feed samples. Aflatoxin B1 was present in the range 28.7-240.1 µg kg(-1), while lower concentrations of sterigmatocystin were found (0.7-2.2 µg kg(-1)). This method may represent a valuable choice, ensuring a high level of accuracy and precision, as well as high-throughput performance. Therefore, it meets the recent EFSA opinion recommendation in terms of availability of fast and sensitive methods (recommended LOQ = 1.5 μg kg(-1)) in order to increase data collection to allow for the assessment of dietary exposure.

    Full Text Available Paleomagnetic and rockmagnetic data are reported for the aeolian Botucatu Formation, in the southern Brazilian State of Rio Grande do Sul. Oriented samples were taken from a section located between the cities of Jaguari and Santiago. After thermal and alternating field demagnetization, both normal and reversed characteristic remanent magnetizations were found. These results yielded 13 reversed and 5 normal polarity sites, composing a magnetostratigraphic column displaying a sequence of reversed-normal-reversed polarity events. The paleomagnetic pole calculated for 18 sites is located at 114.7ºE, 78.5ºS (dp=8.1º; dm=1.2º, after restoring the strata to the paleohorizontal. This paleomagnetic pole indicates a Late Jurassic-Early Cretaceous age to the Botucatu Formation in the investigated area, and places the sampling sites at paleolatitudes as low as 21ºS.Dados paleomagnéticos e de magnetismo de rochas dos sedimentos eólicos da Formação Botucatu, no Estado do Rio Grande do Sul, obtidos de uma seção localizada entre as cidades de Jaguari e Santiago, permitiram definir a idade dessa formação. Direções de magnetização características com polaridades normal e reversa foram obtidas após desmagnetizações térmicas e por campos magnéticos alternados. Do total de sítios amostrados 13 apresentaram polaridade reversa e 5, polaridade normal, compondo uma coluna magnetoestratigráfica onde se identificam três horizontes de polaridade, na ordem, reverso-normal-reverso. O pólo paleomagnético baseado em 18 sítios está localizado a 114.7ºE, 78.5ºS (dp = 8.1º; dm = 1.2º, depois de restaurada a paleohorizontal dos sítios de amostragem. Este pólo paleomagnético indica idade do Jurássico Superior-Cretáceo Inferior para a Formação Botucatu na área estudada, e indica que as paleolatitudes ocupadas eram da ordem de 21ºS.

    Full Text Available América Latina es considerada la región más desigual del planeta. Es el Continente donde, según múltiples fuentes, las polarizaciones son mayores en diversos campos, y el acceso a las oportunidades es marcadamente disímil para los diferentes sectores sociales. ¿Cómo impacta la inequidad latinoamericana el fundamental campo de la salud? ¿Qué problemas determina en esta área decisiva de la vida de las sociedades, y qué obstáculos y trabas pone al avance de los esfuerzos para mejorar la salud?.A pesar de su clara relevancia, este tema ha sido limitadamente puesto a foco. El objetivo de este trabajo es llamar la atención sobre el mismo, y contribuir a estimular este debate tan necesario. Para ello se subraya, en primer término, el papel central de la salud para el desarrollo, se reseñan las amplias brechas que existen, a pesar de ello, a nivel mundial entre países, y a su interior, se encaran ciertos difundidos mitos sobre cómo superar los problemas en salud, se exploran algunos de los principales impactos de la desigualdad de América Latina sobre aspectos básicos del campo de la salud y, finalmente, se sugieren algunas líneas de la gran tarea por realizar para enfrentar el peso de la inequidad sobre la salud pública.

    The Environmental Monitoring Project (PMA) aims to report environmental changes arising from drilling activity, in relation to the marine fauna. This project can also help in the monitoring of accidental spills. Since the professionals spend six hours of the day monitoring the ocean around the rigs, they can locate and identify oil stains, notify the responsible onboard, and also help in the monitoring of the oil stain. Such Project has been developed onboard a drilling unit working in Campos Basin. The results presented here were collected during the drilling activity in Bijupira and Salema fields, by Shell Brasil Petroleo Ltda, from July 13th to October 8th, 2011.

O experimento foi montado em casa de vegetação no Núcleo de Estudos e de Difusão de Tecnologia em Floresta, Recursos Hídricos e Agricultura Sustentável, município de Jerônimo Monteiro, Espírito Santo. A espécie vegetal utilizada foi a Coffea canephora Pierre ex A. Froehner, variedade Robusta Tropical (EMCAPER 8151, cultivada em vaso de 12 litros, por um período de 255 dias. As análises de crescimento foram realizadas 15 dias após o transplantio das mudas e no final do experimento, para determinação de matéria seca total e área foliar. O teor de umidade do solo na capacidade de campo varia com a tensão adotada em sua determinação. As maiores taxas de crescimentos relativo e absoluto do cafeeiro conilon foram obtidas quando a umidade do solo foi mantida na capacidade de campos determinada na tensão de 0,010 MPa no Latossolo Vermelho­Amarelo e de 0,006 MPa no Argissolo Vermelho-Amarelo. As menores taxas de crescimento da cultura foram observa­das na capacidade de campo determinada na tensão de 0,033 MPa, o que inviabiliza a sua adoção na estimativa da lâmina de irrigação utilizando-se a câmara de pressão de Richards.

    Full Text Available En el marco del proceso de contacto interétnico ocurrido hacia fines del siglo XIX y principios del XX en Tierra del Fuego, lo acontecido específicamente en la misión salesiana La Candelaria (Rio Grande cobra relevancia por la variedad de registros y fuentes que dicho escenario ofrece. La aproximación historiográfica permitió generar información acerca de la presencia de tuberculosis como causa principal de muerte entre los aborígenes que vivieron en la misión y sobre la dieta, la actividad física y las condiciones en las que vivieron aquellos. Paralelamente tres campañas de excavación realizadas hasta el momento permitieron exhumar restos óseos humanos de once individuos integrantes de la comunidad Selk'nam del cementerio de la misión. El objetivo de este trabajo es presentar los primeros resultados sobre el relevamiento de patologías nutricionales-metabólicas e infecciosas surgidos de los trabajos de campo realizados por todo el equipo de investigación en dicho cementerio. Los resultados hallados muestran hasta el momento una alta frecuencia de indicadores de stress metabólico-nutricional, mayor a la observada en general en restos de aborígenes de Tierra del Fuego en otros contextos arqueológicos. Además, se observaron lesiones infecciosas inespecíficas que también están presentes en frecuencias altas en casos de tuberculosis

    The Cassini-Huygens mission, a joint collaboration between NASA, ESA and the Italian Space Agency, is approaching its last year of operations after nearly 12 years in orbit around Saturn. Cassini will send back its final bits of unique data on September 15th, 2017 as it plunges into Saturn's atmosphere, vaporizing and satisfying planetary protection requirements. Before that time Cassini will continue its legacy of exploration and discovery with 12 close flybys of Titan in 2016 and 2017 that will return new science data as well as sculpt the inclinations and periods of the final orbits. Even though all of our close icy satellite flybys, including those of Enceladus, are now completed, numerous Voyager-class flybys (summer solstice approaches. In November 2016 Cassini will transition to a series of orbits with peripases just outside Saturn's F ring. These 20 orbits will include close flybys of some tiny ring moons and excellent views of the F ring and outer A ring. The 126th and final close flyby of Titan will propel Cassini across Saturn's main rings and into its final orbits. Cassini's Grand Finale, starting in April 2017, is comprised of 22 orbits at an inclination of 63 degrees. Cassini will repeatedly dive between the innermost rings and the upper atmosphere of the planet providing insights into fundamental questions unattainable during the rest of the mission. Cassini will be the first spacecraft to explore this region. These close orbits provide the highest resolution observations of both the rings and Saturn, and direct in situ sampling of the ring particles, composition, plasma, Saturn's exosphere and the innermost radiation belts. Saturn's gravitational field will be measured to unprecedented accuracy, providing information on the interior structure of the planet, winds in the outer layers of Saturn's atmosphere, and the mass distribution in the rings. Probing the magnetic field will give insight into the nature of the magnetic dynamo, telling us: why the

    Full Text Available Discutimos a possibilidade da inserção da Gerontologia na Tabela das Áreas do Conhecimento do CNPq num cenário em essa tabela vem sendo questionada na comunidade científica, particularmente no que se refere à inclusão de áreas multidisciplinares. A partir de Foucault, entendemos a Árvore do Conhecimento como uma taxonomia, um continuum, onde todas as áreas são colocadas lado a lado, mais próximas ou mais afastadas conforme semelhanças e diferenças entre si. Trata-se de um tratamento linear e finito que estabelece que uma determinada área do conhecimento só pode estar situada num ponto da parte da linha que corresponde a uma grande área. A Gerontologia caracteristicamente multidisciplinar não alcançou lugar nessa taxonomia institucionalizada, seja porque haveria problemas em relação a conceitos, interesses e projeto político em sua constituição como área do conhecimento, seja porque a taxonomia seria incompatível com a multidisciplinaridade. Concluímos que é possível conceber uma nova Tabela de Campos de Conhecimentos e de Saberes e proceder visualizações dos estudos sobre o envelhecimento e sobre toda e qualquer região dos conhecimentos e dos saberes na plenitude de sua muldisciplinaridade e de suas transformações ao longo dos tempos.

    Full Text Available The accepted structure of space and vacuum derives from the results of relativistic cosmology and quantum field theory. It is demonstrated that a chiral interface between enantiomeric regions of a closed universe, or a (right R-Universe and (left L-Universe, related by an element of PCT symmetry along the interface, represents a construct with all the attributes required of the theoretical vacuum, in-so-far as quantum behaviour is then seen to be induced by the vacuum interface. Quantum mechanics emerges as a special case of classical mechanics, rather than the latter being a subset of the former. This removes the quantum-mechanical observational problem, explains the cosmological large-number coincidences, and accounts for the anti-matter in the cosmos.La estructura aceptada del espacio y el vacío se derivan de los resultados de la cosmología relativística y de la teoría cuántica de campo. Se demuestra que una interfaz quiral entre regiones enantioméricas de un universo cerrado, o un universo derecho y un universo izquierdo, relacionados por un elemento de simetría PCT a lo largo de la interfaz, representa un modelo con todos los atributos requeridos por el vacío teórico. Se desprende que el comportamiento cuántico es entonces visto que es inducido por la interfaz de vacío. La mecánica quántica emerge como un caso especial de la mecánica clásica, más bien que siendo la última un subconjunto de la primera. Esto resuelve el problema observacional mecánico cuántico, explica las coincidencias de los grandes números cosmológicos y toma en cuenta la antimateria en el cosmos.

    The Canadian Multiple Sclerosis Working Group (CMSWG) developed practical recommendations in 2004 to assist clinicians in optimizing the use of disease-modifying therapies (DMT) in patients with relapsing multiple sclerosis. The CMSWG convened to review how disease activity is assessed, propose a more current approach for assessing suboptimal response, and to suggest a scheme for switching or escalating treatment. Practical criteria for relapses, Expanded Disability Status Scale (EDSS) progression and MRI were developed to classify the clinical level of concern as Low, Medium and High. The group concluded that a change in treatment may be considered in any RRMS patient if there is a high level of concern in any one domain (relapses, progression or MRI), a medium level of concern in any two domains, or a low level of concern in all three domains. These recommendations for assessing treatment response should assist clinicians in making more rational choices in their management of relapsing MS patients. PMID:23603165

    The Rio Grande River stretches over 2000 miles from the southern Rocky Mountains in Colorado to the tip of Texas where the Rio Grande meets the Gulf of Mexico. It is the natural boundary between U.S. and Mexico from El Paso, TX, to Brownsville, TX. The communities along the border heavily rely upon the Rio Grande as a primary source of water for consumption, agricultural uses, supporting wildlife and recreation. For many years the Rio Grande has been polluted with municipal, industrial, agricultural and farming contaminants from both sides of the border. This pollution has led to the extinction or reduction of certain wildlife species as well as affecting the health of the residences along the border. Even though great strides have been made in monitoring the Rio Grande, there has been a lack of intense monitoring data collection for pollutants such as pesticides. Three sampling sites including Manadas Creek, the Rio Grande River at International Bridge I, and USGS monitoring site 08459200 off of Highway 83 were chosen. The water quality parameters focused include temperature, pH, conductivity, dissolve oxygen (DO), salinity, total dissolved solids, nutrients, metals and pesticides. Preliminary results have shown elevated concentration of total phosphorus and ortho-phosphorus in the Manadas Creek site. Organochlorinated pesticides such as heptachlor and 4, 4 DDE were detected at various concentrations at all sites and endrin aldehyde was found at Manadas Creek site. This research has provided more information on the current chemical contamination level of the Rio Grande in the Laredo area.

Leaves showed uniseriate epidermis in petiole and leaf blade which contains uniseriate nonglandular tricomes (tector type occurring only over the vascular bundles. Likewise, paracytic stomata were found only in abaxial side of the leaf surface. The mesophyll contains uniseriate palisade parenchyma and multiseriate spongy parenchyma (nine layers which showed cells with different morphology and size. Crystal idoblasts of different types were observed in both the petiole and leaf blade. Collateral vascular bundles were found both in the petiole and leaf blade. Leaf venation type was pinnate, campylodromous or brochydodromous. The micromorphometric analysis showed significant differences from plants of different environments for all leaf characteristics and Cerrado plants showed higher means for all evaluated traits. Therefore, the influence of environments may had modulated morphological responses in P. rigida, since no difference was found in the type or distribution of leaf tissues in Cerrado or Campo Rupestre.

    The Brazilian "campo rupestre" vegetation shows high light heterogeneity, characteristic which is often disregarded in ecophysiological studies due the difficult of obtaining accurate measurements in a complex environment. The aim of the present study it was to describe how much heterogeneous is the light distribution in this environment, as well as tried to define classes in relation to the photosynthetically active radiation (PAR) for 30 rupicolous individuals of Bulbophyllum involutum. The individuals were marked and previously classified in light classes visually predetermined ("full sun", "partially shaded" and "shaded"). Once defined these classes, principal component analysis, cluster and dispersal analyses using direct and indirect PAR measures were performed to characterize the environment as well as to validate the inclusion of the individuals in each class. The use of multivariate analysis increased the accuracy of predetermined classes of light, and some individuals from "shaded" and "partially shaded" classes needed to be regrouped. After individuals' reclassification, amplitude of PAR variance was reduced in each class, enhancing homogeneity. Ours results show the possibility to evaluate light environment conditions more precisely in "campo rupestre" vegetation using multivariate analysis, allowing the increase in accuracy of this parameter for ecophysiological researches.

    The constant demand for Services Companies in Oil and Gas Industry to reduce the environmental impacts has led to a race in search of new cleaner technologies. Fluids with low toxicity are the target of research and development by the companies which are committed to ensure the aspects of quality, health, safety and environment from manufacturing up to the use in the final destination of these products. The replacement of these fluids is happening at a larger speed than in the past on the based in two factors: greater awareness on the part of these companies in relation to the environmental and by new environmental laws. The fluids systems used in fracturing operations are not an exception to this rule. Service companies today are in the process of replacing their formulations with systems less aggressive to the environment so-called 'green' systems. In this context the new technological developments of fracturing fluids are of fundamental importance to assist the new environmental requirements of both operators and government regulatory bodies and also to ensure better effectiveness of these products. This paper reports the research, development and application of new environmentally acceptable fracturing fluids technology, reviews the pioneering case histories in offshore operations and the benefits experienced in the Campos Basin - Brazil.

    Amber from the Campo La Granja mine in Chiapas, Mexico, is distinct from other sources of amber in Chiapas. Campo La Granja amber has distinct layers created by successive flows of resin with thin layers of sand on most surfaces. Aquatic and semi-aquatic arthropods are commonly found. Together these pieces of evidence suggest an estuarine environment similar to modern mangrove communities. The aquatic crustaceans are the most intriguing aspect of the biota. A large number of ostracods have been found in the amber-many with their carapaces open, suggesting that they were alive and submerged in water at the time of entombment. The only known examples of brachyuran crabs preserved in amber are found in the Campo La Granja amber. Amphipods, copepods, isopods, and tanaids are also members of the crustacean fauna preserved in amber.

    Economic impact analysis (EIA) of outdoor recreation can provide critical social information concerning the utilization of natural resources. Outdoor recreation and other non-consumptive uses of resources are viewed as environmentally friendly alternatives to extractive-type industries. While outdoor recreation can be an appropriate use of resources, it generates both beneficial and adverse socioeconomic impacts on rural communities. The authors used EIA to assess the regional economic impacts of rafting in Grand Canyon National Park. The Grand Canyon region of northern Arizona represents a rural US economy that is highly dependent upon tourism and recreational expenditures. The purpose of this research is twofold. The first is to ascertain the previously unknown regional economic impacts of Grand Canyon river runners. The second purpose is to examine attributes of these economic impacts in terms of regional multipliers, leakage, and types of employment created. Most of the literature on economic impacts of outdoor recreation has focused strictly on the positive economic impacts, failing to illuminate the coinciding adverse and constraining economic impacts. Examining the attributes of economic impacts can highlight deficiencies and constraints that limit the economic benefits of recreation and tourism. Regional expenditure information was obtained by surveying non-commercial boaters and commercial outfitters. The authors used IMPLAN input-output modeling to assess direct, indirect, and induced effects of Grand Canyon river runners. Multipliers were calculated for output, employment, and income. Over 22,000 people rafted on the Colorado River through Grand Canyon National Park in 2001, resulting in an estimated $21,100,000 of regional expenditures to the greater Grand Canyon economy. However, over 50% of all rafting-related expenditures were not captured by the regional economy and many of the jobs created by the rafting industry are lower-wage and seasonal. Policy

No entanto, tal prática se vê furtivamente ameaçada pelo desprendimento dos valores culturais tradicionais ante o florescer midiático. Objetivo: O presente trabalho postula o resgate da prática da contação de histórias no seio da comunidade rural de Jatobá, município de Janaúba/MG, através de um plano de intervenção pedagógico, como forma de valorizar as tradições e saberes do campo. Metodologia: Através de procedimentos de campo, foram avaliadas as perspectivas da tradição oral, partindo dos moradores mais antigos da localidade em cruzamento de dados com estudantes da escola local. Foi acionada uma entrevista para o primeiro grupo e um questionário para o segundo, buscando diagnosticar e refletir mais profundamente a realidade da tradição. Resultados: Evidenciou-se que a contação de histórias perde espaço no campo. As novas gerações têm pouco comprometimento e conhecimento das tradições e irrefletidamente se desconectam do núcleo cultural identitário de seu povo. A escola tem o papel de ressignificadora de práticas no resgate do berço cultural local. Considerações finais: A narrativa de histórias é uma atividade de potencial pedagógico inestimável, porém se vê em risco de desaparecimento, cumpre o ofício de seu resgate que se concatena ao resgate cultural e identitário de um povo e ao resgate do próprio indivíduo em seus manifestações e memória.

    The residual magnetism is a phenomenon in which the magnetic dipoles of a substance are oriented in a certain degree. On the other hand, when internal forces exist capable of aligning elementary magnetic dipoles of a material, a permanent magnet is obtained. Just as in a conductor or in a material, in the elements of a rotary electrical machine magnetic fields can be induced that produce a residual magnetism or magnetization. In the rotary electrical machines, the magnetization phenomenon causes serious problems, such as the generation of induced currents that propitiate the mechanical wear in bearings, collars, trunnions and inclusive in the shaft, by effects known as pitting, frosting and spark tracks, as well as erroneous readings in vibration and temperature sensors, that in some cases can cause the shut down of the machine. In this article are presented the general concepts on the residual magnetism in rotary electrical machines, the causes that originate it and the problems that arises, as well as the demagnetization of the components that have residual magnetic field. The results obtained by the area of Electrical Equipment of the Instituto de Investigaciones Electricas are revised, during the execution of activities related to the measurement and elimination of the residual magnetic field in rotary electrical machines. [Spanish] El magnetismo residual es un fenomeno en el que los dipolos magneticos de una sustancia se encuentran orientados en un grado determinado. Por otro lado, cuando existen fuerzas internas capaces de alinear los dipolos magneticos elementales de un material, se tiene un iman permanente.

En las maquinas electricas rotatorias, el fenomeno de magnetizacion causa graves problemas, como la generacion de corrientes inducidas que propician el desgaste mecanico

  12. Grand symmetry, spectral action and the Higgs mass

    International Nuclear Information System (INIS)

    In the context of the spectral action and the noncommutative geometry approach to the standard model, we build a model based on a larger symmetry. With this grand symmetry it is natural to have the scalar field necessary to obtain the Higgs mass in the vicinity of 126 GeV. This larger symmetry mixes gauge and spin degrees of freedom without introducing extra fermions. Requiring the noncommutative space to be an almost commutative geometry (i.e. the product of manifold by a finite dimensional internal space) gives conditions for the breaking of this grand symmetry to the standard model

  15. Immunomodulatory treatments and cognition in MS.

    2016-09-01

    Cognitive impairments occur frequently and early in multiple sclerosis (MS) and contribute significantly to a reduced quality of life of patients with MS. Executive functions (EFs) play a pivotal role for the behavioral adaption to the environment and are also crucial for compensatory processes of cognitive impairments. Disease-modifying drugs (DMDs) are effective in reducing the frequency of relapses and slow the disease progression in MS. The effects of DMDs on cognitive impairments were reviewed with a special focus on EFs. Most studies show some beneficial effects of DMDs on cognition in MS, but the evidence for effects on EFs is sparse. Additionally, most studies suffer from methodological issues, small sample sizes and learning effects. We discuss that EFs may constitute a viable cognitive endpoint for cognitive impairments in MS, which could foster the early detection of subtle cognitive changes in MS. PMID:27580907

  16. The role of EBV in MS pathogenesis

    2006-01-01

    Environmental factors operate on a background of genetic susceptibility in the pathogenesis of MS. Human herpesviruses, notably Epstein-Barr virus (EBV), and human endogenous retroviruses are factors associated with MS. EBV association is found in epidemiological surveys where late EBV infection...... confers a higher risk of MS, and EBV reactivation also appears to be linked to disease activity in early MS. MS patients have elevated anti-EBV antibody responses, both in serum and cerebrospinal fluid. Molecular mimicry is found between certain EBV and myelin epitopes in the cell-mediated immune response....... EBV cannot stand alone as a causal factor of MS, but is likely to play an indirect role as an activator of the underlying disease process....

    PETROBRAS E and P department (up-stream segment) had assigned first contract for pipeline inspection using smart pigs in 1995. Up to this time only TRANSPETRO (down-stream segment) had an experience with those inspections mainly focused on first generation tools. On this contract, it was first time required high resolution tools, which had bigger defect detection capability and sizing accuracy as advantages but with higher cost. It was regarded necessary due to high costs involved on a virtual sub sea survey or repair. The investment was regarded fair as there is no way to establish correlation digs as well as normally done after on shore pipelines surveys. Actually the first internal inspection was carried out in 1997. From this period it has been realized the enormous importance on verifying all platforms installations and all procedures involving cleaning runs. We have taken many lessons from these inspections. Commissioning using all kinds of cleaning pigs (some was invented) that could be specially contracted on scaling removing jobs; diesel batch to make easy US pigs inspection, cleaning steps that should be gradual to allow receiving of debris without disturbing platforms process efficiency; special tools designed in-house to meet some specific installations requirements as limited pigability; were some issues that demanded efforts on this period. PETROBRAS/E and P through its Campos Basin Production Unit has been strongly involved on looking for solutions to keep its sub sea pipeline net integrity; a strategic asset that will guarantee the Brazilian development on oil and gas production.

    According to the Brazilian legislation, the Environmental Impacts Monitoring Plan is one of the requirements of the environmental licensing to offshore oil and gas production activities. The Monitoring Plan's structure is based upon sampling and evaluation of numerous parameter settings in water and sediment compartments, while the conclusion as to the existence or absence of impact is obtained after statistical analysis of the results. The aim of this work was to evaluate the methodological adequacy of monitoring and to calculate the statistical power of tests applied with the purpose to determine the reliability of their findings. Experiences in other countries like Australia have shown that this is an important instrument in preparing an effective environmental study regarding the detection of impacts. In Brazil, this is the first initiative to critically evaluate the results of reports of environmental monitoring originated from the licensing of hydrocarbons production activities. Campaign reports forwarded to the environmental agency in charge, i.e., the Brazilian Institute of Environment and Renewable Natural Resources (IBAMA), and the selected ventures are located in the Campos Basin and have different operating companies. The results were both relevant and concerning. All monitoring reports confirmed the absence of alterations or impacts on the biotic media for sediment compartments, but the greater statistical power did not exceed 25% for a great magnitude impact. Thus it was concluded that if the oil production activity has caused alterations or impacts to bentonic organisms, the carried out monitoring was inefficient to detect them even if they were of great magnitude. This analysis is expected to be an instrument for future changes in environmental licensing procedures e for the improvement of the environmental public management in Brazil. (author)

    Within the framework of the program Global Land Ice Measurements from Space (GLIMS) a glacier inventory of the Peninsula Muñoz Gamero in the southernmost Andes of Chile (53°S) has been generated using aerial photopgrahy and Landsat Thematic Mapper imagery. The Peninsula is partly covered by the ice cap of the Gran Campo Nevado (GCN), including several outlet glaciers plus some minor glaciers and firn fields. All together the ice covered areas sum up to 260 km2. GCN forms the only major ice body between the Southern Patagonia Icefield and the Strait of Magallan. Its almost unique location in a zone affected year-round by the westerlies makes it a region of key interest in terms of glacier and climate change studies of the west-wind zone of the Southern Hemisphere. A digital elevation model (DEM) was created for the area, using aerial imagery from 1942, 1984, and 1998 and a Chilean topographic map (1: 100 000). All information was incorporated into a GIS together with satellite imagery from 1986 and 2001. Delineation of glacier inflow from the central plateau of Gran Campo Nevado was accomplished using an automatic module for watershed delineation within the GIS. The GIS served to outline the extent of the present glaciation of the peninsula, as well as to evaluate the derived historic information. The comparison of historic and recent imagery reveals a dramatic glacier retreat during the last 60 years. Some of the outlet glaciers lost more than 20% of their total area during this period. In February and March 2000 a automatic weather station (AWS) was run on a nameless outlet glacier, inofficially Glaciar Lengua, of the Gran Campo Nevado Ice Cap. From the computed energy balance, it was possible to derive degree-day factors for the Glaciar Lengua. With data from the nearby AWS at fjord coast (Bahia Bahamondes) we computed ablation for the summer seasons of 1999/2000, 2000/2001 and 2001/2002. Ablation at 450 m a.s.l. sums up to about 7 m in 1999/2000, 5.5 m in 2000

    The final stage of the Variscan orogeny (310-270 Ma) is characterized by an intense tectonic, magmatic and metamorphic event. During the Permian, acid and mafic intrusions were emplaced at all crustal levels and are associated to high-temperature contact metamorphism. While most of the studies focus either on the formation of Permian basins or on the lower crustal magmatic and metamorphic evolution, the characterization of the middle crust is lacking. Therefore, this study aims to unravel the processes active at mid-crustal levels during the Permian. We investigate the contact aureole of the Sondalo gabbro emplaced in a mid-crustal position during the Permian, exposed in the Austroalpine Campo unit (N-Italy). This work is based on a multidisciplinary approach linking structural geology, metamorphic petrology and geochronology. The country rock of the gabbroic intrusion is composed of Grt-St micaschists and paragneisses indicating a prograde path in the amphibolite facies associated with the formation of a N-W steeply dipping S2 foliation. This foliation is pervasively reworked by a N-E trending sub-vertical S3 fabric made of Ms-Bt metasediments. This S3 fabric is also found in metapelitic septa in the core of the mafic intrusion, whereas in the narrow contact aureole a moderately dipping S4 fabric roughly parallel to the margins of the pluton is developed. From host-rock to the center of the intrusion, the metapelites show destabilization of muscovite, appearance of sillimanite, spinel, cordierite, crystallization of a large amount of garnet and finally disappearance of biotite and potassic feldspar. As a consequence, the kinzigitic restites of the contact aureole are replaced by Grt-Sil-Crd-Spl granulites in an intra-plutonic position. Qualitative P-T estimates indicate a barrovian prograde path during D2, similar to P-T evolutions found in other Austroalpine units (e.g. Ulten zone). Thermodynamic modelling of the high-grade granulites due to the thermal effect of
