In the Cape Caribou River allochthon (CCRA), metaigneous and gneissic units occur as a shallowly plunging synform in the hanging wall of the Grand Lake thrust system (GLTS), a Grenvillian structure that forms the boundary between the Mealy Mountains and Groswater Bay terranes. The layered rocks of the CCRA are cut by a stockwork of monzonite dykes related to the Dome Mountain suite and by metadiabase-amphibolite dykes that probably form part of the ca. 1380 Ma Mealy swarm. The mafic dykes appear to postdate much of the development of subhorizontal metamorphic layering within the lower parts of the CCRA. The uppermost (least metamorphosed) units of the CCRA, the North West River anorthosite-metagabbro and the Dome Mountain monzonite suite, have been dated at 1625 +/- 6 and 1626 +/- 2 Ma, respectively. An amphibolite unit that concordantly underlies the anorthosite-metagabbro and is intruded discordantly by monzonite dykes has given metamorphic ages of 1660 +/- 3 and 1631 +/- 2 Ma. Granitoid gneisses that form the lowest level of the CCRA have given a migmatization age of 1622 +/- 6 Ma. The effects of Grenvillian metamorphism become apparent in the lower levels of the allochthon where gneisses, amphibolite, and mafic dykes have given new generation zircon ages of 1008 +/- 2, 1012 +/- 3, and 1011 +/- 3 Ma, respectively. A posttectonic pegmatite has also given zircon and monazite ages of 1016(-3)(+7) and 1013 +/- 3 Ma, respectively. Although these results indicate new growth of Grenvillian zircon, this process was generally not accompanied by penetrative deformation or melting. Thus, the formation of gneissic fabrics and the overall layered nature of the lower CCRA are a result primarily of Labradorian (1660-1620 Ma) tectonism and intrusion, and probably reflect early movement on an ancestral GLTS. Grenvillian heating and metamorphism (up to granulite facies) was strongly concentrated towards the base of the CCRA and probably occurred during northwestward thrusting of the allochthon over the Groswater Bay terrane.

Extensional detachment systems separate hot footwalls from cool hanging walls, but the degree to which this thermal gradient is the product of ductile or brittle deformation or a preserved original transient geotherm is unclear. Oxygen isotope thermometry using recrystallized quartz-muscovite pairs indicates a smooth thermal gradient (140 degrees C/100 m) across the gently dipping, quartzite-dominated detachment zone that bounds the Raft River core complex in northwest Utah (United States). Hydrogen isotope values of muscovite (delta D-Ms similar to-100 parts per thousand) and fluid inclusions in quartz (delta D-Fluid similar to-85 parts per thousand) indicate the presence of meteoric fluids during detachment dynamics. Recrystallized grain-shape fabrics and quartz c-axis fabric patterns reveal a large component of coaxial strain (pure shear), consistent with thinning of the detachment section. Therefore, the high thermal gradient preserved in the Raft River detachment reflects the transient geotherm that developed owing to shearing, thinning, and the potentially prominent role of convective flow of surface fluids.

Este estudo teve como objetivo identificar e caracterizar os profissionais de enfermagem que prestam assistência ao parto, nas maternidades do município de Rio Branco-AC. Foi realizado nas duas maternidades do Município. A população estudada foi composta por 30 profissionais de enfermagem. Os dados foram coletados por meio de entrevistas. Os resultados mostraram que, dos 25 (83,3%) profissionais de enfermagem que realizam parto normal, 18 (72%) receberam treinamento por meio de educação informal, isto é, acompanhando e sendo acompanhados por outro profissional durante a jornada de trabalho. Conclui-se que, segundo critérios da Organização Mundial de Saúde, apenas sete (28%) profissionais de enfermagem, que prestam assistência à parturiente, são considerados qualificados para este atendimento, revelando que existe necessidade de qualificação de grande parte da equipe que atende as mulheres e seus recém-nascidos durante o parto e nascimento, nas instituições de saúde de Rio Branco.

Self-potentials (SP) are sensitive to water fluxes and concentration gradients in both saturated and unsaturated geological media, but quantitative interpretations of SP field data may often be hindered by the superposition of different source contributions and time-varying electrode potentials. Self-potential mapping and close to two months of SP monitoring on a gravel bar were performed to investigate the origins of SP signals at a restored river section of the Thur River in northeastern Switzerland. The SP mapping and subsequent inversion of the data indicate that the SP sources are mainly located in the upper few meters in regions of soil cover rather than bare gravel. Wavelet analyses of the time-series indicate a strong, but non-linear influence of water table and water content variations, as well as rainfall intensity on the recorded SP signals. Modeling of the SP response with respect to an increase in the water table elevation and precipitation indicate that the distribution of soil properties in the vadose zone has a very strong influence. We conclude that the observed SP responses on the gravel bar are more complicated than previously proposed semi-empiric relationships between SP signals and hydraulic head or the thickness of the vadose zone. We suggest that future SP monitoring in restored river corridors should either focus on quantifying vadose zone processes by installing vertical profiles of closely spaced SP electrodes or by installing the electrodes within the river to avoid signals arising from vadose zone processes and time-varying electrochemical conditions in the vicinity of the electrodes.

A validation study has been performed using the Soil and Water Assessment Tool (SWAT) model with data collected for the Upper Maquoketa River Watershed (UMRW), which drains over 16,000 ha in northeast Iowa. This validation assessment builds on a previous study with nested modeling for the UMRW that required both the Agricultural Policy EXtender (APEX) model and SWAT. In the nested modeling approach, edge-offield flows and pollutant load estimates were generated for manure application fields with APEX and were then subsequently routed to the watershed outlet in SWAT, along with flows and pollutant loadings estimated for the rest of the watershed routed to the watershed outlet. In the current study, the entire UMRW cropland area was simulated in SWAT, which required translating the APEX subareas into SWAT hydrologic response units (HRUs). Calibration and validation of the SWAT output was performed by comparing predicted flow and NO3-N loadings with corresponding in-stream measurements at the watershed outlet from 1999 to 2001. Annual stream flows measured at the watershed outlet were greatly under-predicted when precipitation data collected within the watershed during the 1999-2001 period were used to drive SWAT. Selection of alternative climate data resulted in greatly improved average annual stream predictions, and also relatively strong r2 values of 0.73 and 0.72 for the predicted average monthly flows and NO3-N loads, respectively. The impact of alternative precipitation data shows that as average annual precipitation increases 19%, the relative change in average annual streamflow is about 55%. In summary, the results of this study show that SWAT can replicate measured trends for this watershed and that climate inputs are very important for validating SWAT and other water quality models.

Realizou-se estudo comparativo randomizado para avaliar o controle de hipertensos, com uso da medida residencial da pressão arterial (MRPA) e medida casual, bem como para analisar o efeito do avental branco. Hipertensos atendidos em unidades básicas de saúde foram divididos aleatoriamente em: grupo I, participante das atividades educativas, e grupo II, que seguiu a rotina de atendimento. Os hipertensos do grupo I realizaram MRPA no início e final do estudo. Efeito do avental branco foi avaliado pela diferença entre a medida casual e MRPA. Foram incluídos 290 hipertensos, porém realizaram MRPA 82 hipertensos. Houve aumento no controle da pressão do início ao final do estudo nos hipertensos do grupo I (p < 0,05) avaliado pela MRPA (60% para 68,3%) e pela medida casual (62% para 71%); no grupo II o controle foi maior na MRPA do que na medida casual (63% vs 50%). O efeito do avental branco foi maior no grupo II.

The objective of the study presented in this report was to document the launch of the Iowa River Bridge and to monitor and evaluate the structural performance of the bridge superstructure and substructure during the launch. The Iowa Department of Transportation used an incremental launching method, which is relatively unique for steel I-girder bridges, to construct the Iowa River Bridge over an environmentally sensitive river valley in central Iowa. The bridge was designed as two separate roadways consisting of four steel plate girders each that are approximately 11 ft deep and span approximately 301 ft each over five spans. The concrete bridge deck was not placed until after both roadways had been launched. One of the most significant monitoring and evaluation observations related to the superstructure was that the bottom flange (and associated web region) was subjected to extremely large stresses during the crossing of launch rollers. Regarding the substructure performance, the column stresses did not exceed reasonable design limits during the daylong launches. The scope of the study did not allow adequate quantification of the measured applied launch forces at the piers. Future proposed esearch should provide an opportunity to address this. The overall experimental performance of the bridge during the launch was compared with the predicted design performance. In general, the substructure design, girder contact stress, and total launching force assumptions correlated well with the experimental results. The design assumptions for total axial force in crossframe members, on the other hand, differed from the experimental results by as much as 300%.

A exploração dos resultados do estudo revela que tanto a informação como o trabalho monográfico que hora se apresenta espelha um estudo elaborado no quadro do curso de Educação de infância da Universidade de Cabo Verde, como uma das exigências para obtenção do grau de Licenciatura, sob a temática “Problema de Frequência do Pré-Escolar na Comunidade dos Rabelados em Espinho Branco S. Miguel – Ilha de Santiago”. Procura-se neste trabalho trazer para debate a problemática de frequência do pré-escolar na Comunidade, bem como o que pensem os pais que não matricularam os seus filhos nesse jardim,ou seja que perspectivas futura para essas crianças e comunidade em geral,visto que há crianças estão dentro do sistema do ensino pré- escolar e que moram em “funcos” tradicionais, assim como outras que se encontram fora do sistema. Convém referir ainda que cinquenta por centro das crianças inscritas no pré- escolar estão registadas e outras não, numa perspectiva de melhoria das prestações auferidas. Centrada em duas abordagens, uma teórica e outra prática, este trabalho projecta de forma resumida alguns pensamentos cujo relevância está na sua estreita ligação com a temática que aqui se desenvolve, sempre em perfeita harmonia com a realidade, objecto do estudo. Conhecer o papel do pré-escolar no desenvolvimento das crianças; conhecer o pensamento dos pais sobre a problemática em estudo. Entre os diversos autores citados, registam-se os trabalhos desenvolvidos por FREDERICO FROEBOL (1783-1852), e Maria Montessori (1870-1952) que proponham peculiares para o desenvolvimento do trabalho pedagógico com crianças; por alguns clássicos psicólogos e sociólogos tais como Piaget (1946-1983), Erickson (1976). Esta rica explanação culmina com uma exploração dos dados resultante de observações, entrevistas cuja pretensão era de auscultar e analisar as opiniões dos diversos intervenientes quanto ao problema de frequência do pré-escolar na comunidade dos rabelados em Espinho Branco S. Miguel – Ilha de Santiago. A frequência do pré-escolar revela como de essencial a contribuir para melhoria de uma comunidade, como tal a dos rabelados em espinho Branco, S. Miguel – Ilha de Santiago.

sobre qualidade de vida, passa sempre pela vivência de actividades de lazer no “tempo livre” como sendo fundamentais para uma melhoria na condição geral de vida das pessoas. Devido à importância atribuída ao desporto e ao lazer em nossa sociedade, tais temas, nas últimas décadas, têm sido objectos de estudo e de discussões no meio académico-científico. Entendemos que a criação/existência/satisfação das necessidades sociais e individuais de lazer envolve “hábitos de consumo”, os quais estão ligados aos “estilos de vida”.
