Variáveis evidenciadoras dos processos de transformação do campo : O caso do Espírito Santo - Brasil

This article aims to analyze the occurrence of changes in the countryside, in Brazil, from the observation of variables such as type of job, income, family profile, access to consumer goods, services, and information and communication technology. There had been used exploratory analysis and logistic regression method, based on data from the Pesquisa Nacional de Amostra de Domicílios (Brazilian National Household Sample Survey - PNAD) for the state of Espirito Santo. The study found that about 27.2 of individuals who had lived in the countryside report an urban profile, revealing that the urban lifestyle is encompassed not only in the city

Desempenho propulsivo de embarcações de pesca: estudo aplicado à melhoria das embarcações do Espírito Santo.

Este trabalho apresenta um procedimento simples e robusto para avaliação e análise do desempenho de instalações propulsoras de embarcações de pesca operando no Estado do Espírito Santo. O objetivo é verificar se as embarcações estão operando com baixa eficiência propulsiva, portanto, com consumo de combustível maior do que o desejável, e identificar possíveis ações de melhoria desta eficiência que poderiam ser implementadas com baixo custo. Tendo em vista as condições artesanais da construção e operação das embarcações de pesca no Espírito Santo, o procedimento foi desenvolvido de forma a poder ser aplicado com relativa facilidade pelas pessoas envolvidas na atividade pesqueira artesanal neste Estado. O procedimento envolve o levantamento de informações sobre a geometria do casco, as características da instalação propulsora existente e sobre alguns aspectos do desempenho das embarcações. Para este levantamento são propostos métodos e técnicas suficientemente simples para que possam ser facilmente aplicadas nos estaleiros. Com base nestes dados levantados implementou-se no procedimento proposto diversos algoritmos que permitem determinar o coeficiente propulsivo das embarcações de pesca e a perda de energia útil que ocorre tanto no motor, por conta de condições inadequadas de operação, quanto na transmissão desta energia para o hélice. Para a validação dos métodos e técnicas envolvidos neste procedimento e dos resultados fornecidos por ele, o mesmo foi aplicado em alguns cascos de embarcações de pesca disponíveis em estaleiros visitados no Estado. Para uma destas embarcações o procedimento foi aplicado em sua totalidade, permitindo identificar a baixa eficiência da instalação propulsora e algumas das possíveis causas que provocam a perda de energia útil no sistema. Finalmente, com base nesse exemplo de aplicação, um estudo de possíveis melhorias na instalação propulsora é apresentado ao final do trabalho.

Diagnóstico e análise funcional da implementação do Sistema Pyxis no Serviço de Urgência do Hospital Espírito Santo- Évora

Atualmente, existe interesse em determinar o benefício ou contributo do estudo de um determinado tópico para a prática em enfermagem e melhoria do serviço ao utente, o que é percetível na necessidade detetada nessa prática de disponibilizar o medicamento no local adequado, na quantidade exigida e no tempo e gasto mínimos. Neste sentido, verifica-se que o Hospital do Espirito Santo Évora (HESE) adquiriu o sistema Pyxis em 2007 e, até à data, não foi implementado sem se perceber as razões para tal, quer sejam de natureza técnica quer de gestão, o que desperta o interesse no tratamento deste assunto e a relevância do tema. Assim, levanta-se a questão sobre as condições de implementação do Pyxis, o que se traduz num problema, para o qual se procura uma solução com uma metodologia adequada. O presente trabalho tem como objetivo preparar as condições para a implementação do Pyxis. Assim, pretende-se analisar a situação presente e identificar as necessidades de alteração e de ajustamento suportadas nas exigências e requisitos do sistema Pyxis, no que se refere à sua implementação. Em termos metodológicos, para prosseguir o objetivo antes referido, recorre-se ao diagnóstico interno, à descrição do Pyxis, para identificação das condições da sua implementação, à análise funcional e à elaboração do instrumento de inquérito através de questionário, para posterior aplicação. Os resultados obtidos permitem uma verificação dos requisitos e alterações, para a implementação do sistema Pyxis, bem como os benefícios associados a este sistema. Existe a evidência de que o sistema Pyxis é uma nova tecnologia que possibilita ao HESE a diminuição do tempo utilizado pela equipa de saúde no processo logístico de distribuição do medicamento e a melhoraria da qualidade através da diminuição de erro de medicação, sendo fundamental na qualidade dos cuidados de saúde a prestar aos utentes, o que é concordante com o enquadramento teórico efetuado

Study of calcium oxalate monohydrate of kidney stones by X-ray diffraction

X-ray powder diffraction was used to study the phase composition of human renal calculi. The stones were collected from 56 donors in Vitoria, Espirito Santo state, southeastern Brazil. An XRD phase quantification revealed that 61% of the studied renal stones were composed exclusively of calcium oxalate [34% formed only by calcium oxalate rnonohydrate (COM) and 27% presents both monohydrate and dihydratate calcium oxalate]. The 39% multi-composed calculi have various other phases such as uric acid and calcium phosphate. Rietveld refinement of XRD data of one apparent monophasic (COM) renal calculus revealed the presence of a small amount of hydroxyapatite. The presence of this second phase and the morphology of the stone (ellipsoidal) indicated that this calculus can be classified as non-papillary type and its nucleation process developed in closed kidney cavities. In order to show some advantages of the X-ray powder diffraction technique, a study of the phase transformation of monohydrate calcium oxalate into calcium carbonate (CaCO(3)) was carried out by annealing of a monophasic COM calculi at 200, 300, and 400 degrees C for 48 h in a N(2) gas atmosphere. The results of the XRD for the heat treated samples is ill good agreement with the thermogravimetric analysis found in the literature and shows that X-ray powder diffraction can be used as a suitable technique to study the composition and phase diagram of renal calculi.

Parametric model for the analysis of concrete expansion due to alkali-aggregate reaction

The alkali-aggregate reaction (AAR) is a chemical reaction that provokes a heterogeneous expansion of concrete and reduces important properties such as Young's modulus, leading to a reduction in the structure's useful life. In this study, a parametric model is employed to determine the spatial distribution of the concrete expansion, combining normalized factors that influence the reaction through an AAR expansion law. Optimization techniques were employed to adjust the numerical results and observations in a real structure. A three-dimensional version of the model has been implemented in a finite element commercial package (ANSYS(C)) and verified in the analysis of an accelerated mortar test. Comparisons were made between two AAR mathematical descriptions for the mechanical phenomenon, using the same methodology, and an expansion curve obtained from experiment. Some parametric studies are also presented. The numerical results compared very well with the experimental data validating the proposed method.

Spiranthera atlantica (Rutaceae, Galipeae), a New Species and the First Record of the Genus for the Brazilian Atlantic Forest

A new species of Spiranthera A. St.-Hil. (Rutaceae, Galipeinae) is illustrated and described from Espirito Santo, Brazil. Spiranthera atlantica Pi rani represents the first species record for the genus in the Atlantic Forest of eastern Brazil. The new (axon resembles the Amazonian S. guianensis Sandwith but differs by its smaller, few-flowered inflorescences and by the fruit and leaflet morphology.

A New Genus of Microteiid Lizard from the Caparao Mountains, Southeastern Brazil, with a Discussion of Relationships among Gymnophthalminae (Squamata)

A new genus and species of microteiid lizard is described based on a series of specimens obtained at Parque Nacional do Caparao (20 degrees 28'S, 41 degrees 49'W), southeastern Brazil, along the division line between the States of Minas Gerais and Espirito Santo. The new lizard occurs in isolated high-altitude, open, rocky habitats above the altitudinal lit-nits of the Atlantic forest. It is characterized by the presence of prefrontals, frontoparietals, parietals, interparietal, and occipital scales; ear opening and eyelid distinct; three pairs of genials; absence of collar; lanceolate and mucronate dorsal scales; six regular transverse and longitudinal series of smooth ventrals that are longer than wide, with the lateral ones narrower. Maximum parsimony (MP) and partitioned Bayesian (PBA) phylogenetic analyses based on morphological and molecular characters with all known genera of Gymnophthalminae (except for Scriptosaura) Plus Rhachisaurus recovered this new lizard in a clade having Colobodactylus and Heterodactylus as its closest relatives. Both analyses recovered the monophyly of Gymnophthalminae and Gymnophthalmini. The monophyly of the Heterodactylini received moderate support in MP analyses but was not recovered in PBA. To eliminate classification controversy between these results, the present concept of Heterodactylini is restricted to accommodate the new genus, Colobodactylus and Heterodactylus, and a new tribe Iphisiini is proposed to allocate Alexandresaurus, Iphisa, Colobosaura, Acratosaura, and Stenolepis. Current phylogenetic knowledge of Gymnophthalminae suggests that fossoriality and increase of body elongation arose as adaptive responses to avoid extreme surface temperatures, either cold or hot, depending on circumstances.

INTERANNUAL VARIABILITY IN TROPICAL ESTUARINE COPEPOD ASSEMBLAGES OFF NORTHEASTERN BRAZIL

We studied copepod assemblage variability among years, seasons, and tidal states in the Mucuri River estuary (Bahia State, Brazil). Zooplankton samples were collected seasonally through five years (2002-2006) at three sampling stations, one of which was sampled over a complete tidal cycle (two ebb and two flood tides). Temperature, salinity, river flux, and rainfall data were collected. Winter and summer represented dry and wet seasons, respectively. Copepod abundances ranged from 40 to 63% of the total zooplankton assemblage and comprised 46 taxa, among which, common estuarine species such as Temora turbinata (first record for the studied area), Parvocalanus crassirostris, Acartia lilljeborgi, Oithona hebes were the most abundant (euryhaline species). Interannual and seasonal variations were most marked in stenohaline species, e.g.. Notodiaptomus sp. and Thermocyclops minutus; density variations of euryhaline species, which made up the majority of the abundant taxa, were most closely related to tides. Diversity and richness also followed an intertidal pattern of variation.

New records of Rhagomys rufescens (Rodentia : Sigmodontinae) in the Atlantic forest of Brazil

Since it was trapped in the XIX(th) century, Rhagomys rufescens has been considered a rare endangered sigmodontine rodent and an endemic species of the Atlantic forest. Only a handful of vouchers of this taxon were known by Thomas, 1886. Recently, eight new individuals were collected, providing new geographical, morphological and phylogenetic (based on molecular evidence) information on this species. In the present work we report the southernmost occurrence record for R. rufescens at Indaial, Santa Catarina State, with the largest collected series of this species, the northernmost occurrence record at Santa Teresa, Espirito Santo State, and new records from Pocos de Caldas, Minas Gerais State, from Ibiuna and Ribeirao Grande, Sao Paulo State.

Increased electronegative LDL and decreased antibodies against electronegative LDL levels correlate with inflammatory markers and adhesion molecules in hemodialysed patients

Background: Chronic Kidney Disease (CKD) patients present high levels of electronegative LDL (LDL) that can modulate the expression of molecules involved in inflammation and it is closely linked to atherosclerosis. We investigated the association between LDL(-) and inflammatory markers in patients undergoing hemodialysis (HD). Methods: Forty-seven HD patients from a private clinic in Rio de Janeiro, Brazil were studied and compared with 20 age matched healthy individuals. Serum LDL(-) and anti-LDL(-) autoantibody levels were measured by ELISA; TNF-alpha, IL-6, VCAM-1 and ICAM-1 were determined by a multiplex assay kit. Results: HD patients presented higher IL-6 and TNF-alpha concentrations (4.1 +/- 1.6 and 5.5 +/- 2.1 pg/ml, respectively) than healthy subjects (2.6 +/- 0.2 and 2.4 +/- 1.1 pg/ml, respectively) (p = 0.0001). In addition, they presented higher VCAM-1 and ICAM-1 levels and, LDL(-) concentrations were also increased (0.18 +/- 0.12 U/I) when compared to healthy individuals (0.10 +/- 0.08 U/I) (p<0.02). In contrast, the anti-LDL(-) autoantibody levels were lower in HD patients (0.02 +/- 0.01 mg/l) than in healthy subjects (0.05 +/- 0.03 mg/l) (p<0.001). There was a positive correlation between LDL(-) and IL-6 (r = 0.25, p = 0.004) and ICAM-1 (r = 0.36; p = 0.003). There was also a negative correlation between anti-LDL(-) autoantibodies and TNF-alpha (r = -0.37; p = 0.003) and VCAM-1 (r = -0.50; p = 0.0001). Conclusions: The association between LDL(-) and inflammation and the lower levels of anti-LDL(-) autoantibodies are important risk factors related to atherosclerosis in CKD.
