Identificação e análise dos/as pobres como categoria social: uma pesquisa bíblica a partir de contextos histórico-sociais na subunidade dos Salmos 3-14

A pesquisa, em 5 capítulos, desenvolve o tema dos/as pobres como categoria social nos Sl 3-14, subunidade do primeiro livro do saltério (Sl 3-41). Os Sl 3-14 são atribuídos a Davi, o fato está relacionado com as escolas e suas teologias presentes na edição final do saltério. Esses salmos nasceram nas comunidades camponesas do antigo Israel, posteriormente, foram aperfeiçoados e adaptados por grupos de cantores oficiais no templo de Jerusalém. Os Sl 3-14 se destacam pelo lamento e pela súplica individual. Pertencem a uma coleção pré-exílica, mas concentra textos tardios, do pós-exílio. Os lugares que ocupam foram pensados estrategicamente. Os Sl 9; 10 apresentam conceitos hebraicos que identificam os/as pobres: dak, ani, ebyon. Estes/as designam pequenos/as camponeses/as livres, ainda com acesso à terra. Ao longo do antigo Israel não sofreram mudanças bruscas como categoria social, no entanto, podem assinalar-se algumas características que os/as distinguem nos períodos correspondentes ao primeiro e o segundo templo de Jerusalém. Ademais, os Sl 9; 10 apresentam palavras sinônimas que também os/as identificam: hellkah pobre/infeliz e naqi inocente . Apesar das pequenas variações dos conceitos, todos apontam à uma categoria social, com direito à apelação nos tribunais, embora com fraca influência jurídica. Essa comunidade tem identidade teológica. Javé é apresentado como o seu defensor. A espoliação no saltério é algo dramático, porque o rosto do/a pobre é o próprio rosto de Javé. A pobreza não é um assunto de espiritualidade nem de casualidade. É gerada por um sistema político-social, planejado de forma inteligente, que não permite ao povo da roça progredir como agricultor. Esse setor poderoso, nacional ou estrangeiro, é identificado nos textos, sob os conceitos: goyim nações , sorerim agressores , oyebim inimigos , raxa im injustos . O seu domínio é suportado pela violência e as armas. A ideologia dos sistemas dominantes é fundamental para a interpretação dos textos. A sociedade dos salmistas apresenta crises com relação à identidade humana. A violência e a paz se disputam os espaços. O Sl 8 mostra uma sociedade alternativa pensada a partir daquilo aparentemente fraco: as olelim crianças e os yanaqim lactantes (Sl 8,3). O grito das criancinhas, o grito dos/as oprimidos/as, unido ao grito da criação, se compara à dor de parto, com o qual inicia a vida. Trata-se de um grito que busca transformar os trajetos entortados da história. Esses são indícios da esperança que distingue a teologia dos/as pobres. Os Sl 3-7 e 11-14 continuam a apresentar a situação dos/as pobres. Às vezes, localizam-se os conceitos: ani oprimido e ebyon pobre , outras, recorre-se a novos sinônimos como has͇id fiel e sadiq justo . Esses salmos demonstram que os/as pobres estão presentes também nos textos onde tais conceitos não aparecem. As agrupações (Sl 3-7 e 11-14) são uma pausa na subunidade (Sl 3-14), não uma quebra de sentido com os Sl 8; 9 e 10. Finalmente, se localiza na sociedade dos Sl 3-14, o Modo de Produção Tributário. As teorias das ciências econômica, arqueológica, histórica, contribuem com a compreensão do universo sóciopolítico gerador de pobres.

STRESS E REAJUSTAMENTO SOCIAL EM AUXILIARES DE ENFERMAGEM

O presente estudo teve por objetivos, levantar o perfil sócio-demográfico e cultural, de auxiliares de enfermagem, avaliar o grau e presença de sintomas de stress, avaliar e descrever reajustamento social tecendo relação entre variáveis relacionadas ao labor e o stress. Participaram desse estudo 126 auxiliares de enfermagem que cursavam técnico em enfermagem. Utilizou-se os instrumentos: a) questionário Sócio-demográfico e cultural; b) Escala de Reajustamento Social de Holmes-Rahe e c) Inventário de Sintomas de Stress de Lipp (ISSL). Os dados foram coletados em salas de aula, de três escolas técnicas da grande São Paulo e esses dados foram tratados estatisticamente pelos testes X² e r Person para as relações entre variáveis, com auxílio do programa SPSS versão 17. Os resultados indicaram uma predominância de pessoas do gênero feminino, casados, com idade mínima de 19 anos e máxima de 56 anos e com práticas religiosas católicas e evangélicas. Desses profissionais (79%) trabalhavam em um só emprego, com experiência na profissão de cinco anos e o setor com maior quantidade de profissionais foi o home care . A maioria dos profissionais exercia suas atividades no horário matutino, e estudava no horário noturno. O estudo indicou que 57,9% apresentaram grau de stress significativo. Dentro deste grau de stress significativo, 41,3% dos profissionais estavam na fase de resistência e 37,3% dos auxiliares com grau de stress significativo, apresentavam predominância de stress de natureza psicológica. Quanto ao reajustamento social, os auxiliares de enfermagem a maioria, que correspondia a 48,4% estava dentro da média, com chances razoáveis de adoecer, ou seja, apresentavam capacidade regular para adaptação aos eventos novos e desconhecidos que ocorrem durante a vida. Os resultados indicaram que os profissionais que apresentaram stress significativo obtiveram pontuação maior (média) na escala de reajustamento social, em comparação aos profissionais que não apresentaram stress, indicando que esses sujeitos tinham maior probabilidade de estarem adoecidos ou virem a adoecer.

Flow patterns, performance and scale-up of distillation trays

This work is concerned with the nature of liquid flow across industrial sieve trays operating in the spray, mixed, and the emulsified flow regimes. In order to overcome the practical difficulties of removing many samples from a commercial tray, the mass transfer process was investigated in an air water simulator column by heat transfer analogy. The temperature of the warm water was measured by many thermocouples as the water flowed across the single pass 1.2 m diameter sieve tray. The thermocouples were linked to a mini computer for the storage of the data. The temperature data were then transferred to a main frame computer to generate temperature profiles - analogous to concentration profiles. A comprehensive study of the existing tray efficiency models was carried out using computerised numerical solutions. The calculated results were compared with experimental results published by the Fractionation Research Incorporation (FRl) and the existing models did not show any agreement with the experimental results. Only the Porter and Lockett model showed a reasonable agreement with the experimental results for cenain tray efficiency values. A rectangular active section tray was constructed and tested to establish the channelling effect and the result of its effect on circular tray designs. The developed flow patterns showed predominantly flat profiles and some indication of significant liquid flow through the central region of the tray. This comfirms that the rectangular tray configuration might not be a satisfactory solution for liquid maldistribution on sieve trays. For a typical industrial tray the flow of liquid as it crosses the tray from the inlet to the outlet weir could be affected by the mixing of liquid by the eddy, momentum and the weir shape in the axial or the transverse direction or both. Conventional U-shape profiles were developed when the operating conditions were such that the froth dispersion was in the mixed regime, with good liquid temperature distribution while in the spray regime. For the 12.5 mm hole diameter tray the constant temperature profiles were found to be in the axial direction while in the spray regime and in the transverse direction for the 4.5 mm hole tray. It was observed that the extent of the liquid stagnant zones at the sides of the tray depended on the tray hole diameter and was larger for the 4.5 mm hole tray. The liquid hold-up results show a high liquid hold-up at the areas of the tray with low liquid temperatures, this supports the doubts about the assumptions of constant point efficiency across an operating tray. Liquid flow over the outlet weir showed more liquid flow at the centre of the tray at high liquid loading with low liquid flow at both ends of the weir. The calculated results of the point and tray efficiency model showed a general increase in the calculated point and tray efficiencies with an increase in the weir loading, as the flow regime changed from the spray to the mixed regime the point and the tray efficiencies increased from approximately 30 to 80%.Through the mixed flow regime the efficiencies were found to remain fairly constant, and as the operating conditions were changed to maintain an emulsified flow regime there was a decrease in the resulting efficiencies. The results of the estimated coefficient of mixing for the small and large hole diameter trays show that the extent of liquid mixing on an operating tray generally increased with increasing capacity factor, but decreased with increasing weir loads. This demonstrates that above certain weir loads, the effect of eddy diffusion mechanism on the process of liquid mixing on an operating tray to be negligible.

The role of heterodimerization between VEGFR-1 and VEGFR-2 in the regulation of endothelial cell homeostasis

VEGF-A activity is tightly regulated by ligand and receptor availability. Here we investigate the physiological function of heterodimers between VEGF receptor-1 (VEGFR-1; Flt-1) and VEGFR-2 (KDR; Flk-1) (VEGFR(1-2)) in endothelial cells with a synthetic ligand that binds specifically to VEGFR(1-2). The dimeric ligand comprises one VEGFR-2-specific monomer (VEGF-E) and a VEGFR-1-specific monomer (PlGF-1). Here we show that VEGFR(1-2) activation mediates VEGFR phosphorylation, endothelial cell migration, sustained in vitro tube formation and vasorelaxation via the nitric oxide pathway. VEGFR(1-2) activation does not mediate proliferation or elicit endothelial tissue factor production, confirming that these functions are controlled by VEGFR-2 homodimers. We further demonstrate that activation of VEGFR(1-2) inhibits VEGF-A-induced prostacyclin release, phosphorylation of ERK1/2 MAP kinase and mobilization of intracellular calcium from primary endothelial cells. These findings indicate that VEGFR-1 subunits modulate VEGF activity predominantly by forming heterodimer receptors with VEGFR-2 subunits and such heterodimers regulate endothelial cell homeostasis.

Autocrine activity of soluble Flt-1 controls endothelial cell function and angiogenesis

Background - The negative feedback system is an important physiological regulatory mechanism controlling angiogenesis. Soluble vascular endothelial growth factor (VEGF) receptor-1 (sFlt-1), acts as a potent endogenous soluble inhibitor of VEGF- and placenta growth factor (PlGF)-mediated biological function and can also form dominant-negative complexes with competent full-length VEGF receptors. Methods and results - Systemic overexpression of VEGF-A in mice resulted in significantly elevated circulating sFlt-1. In addition, stimulation of human umbilical vein endothelial cells (HUVEC) with VEGF-A, induced a five-fold increase in sFlt-1 mRNA, a time-dependent significant increase in the release of sFlt-1 into the culture medium and activation of the flt-1 gene promoter. This response was dependent on VEGF receptor-2 (VEGFR-2) and phosphoinositide-3'-kinase signalling. siRNA-mediated knockdown of sFlt-1 in HUVEC stimulated the activation of endothelial nitric oxide synthase, increased basal and VEGF-induced cell migration and enhanced endothelial tube formation on growth factor reduced Matrigel. In contrast, adenoviral overexpression of sFlt-1 suppressed phosphorylation of VEGFR-2 at tyrosine 951 and ERK-1/-2 MAPK and reduced HUVEC proliferation. Preeclampsia is associated with elevated placental and systemic sFlt-1. Phosphorylation of VEGFR-2 tyrosine 951 was greatly reduced in placenta from preeclamptic patients compared to gestationally-matched normal placenta. Conclusion - These results show that endothelial sFlt-1 expression is regulated by VEGF and acts as an autocrine regulator of endothelial cell function.

Loss of Akt activity increases circulating soluble endoglin release in preeclampsia:identification of inter-dependency between Akt-1 and heme oxygenase-1

Aims - Endothelial dysfunction is a hallmark of preeclampsia. Desensitization of the phosphoinositide 3-kinase (PI3K)/Akt pathway underlies endothelial dysfunction and haeme oxygenase-1 (HO-1) is decreased in preeclampsia. To identify therapeutic targets, we sought to assess whether these two regulators act to suppress soluble endoglin (sEng), an antagonist of transforming growth factor-ß (TGF-ß) signalling, which is known to be elevated in preeclampsia. Methods and results - Vascular endothelial growth factor-A (VEGF-A), fibroblast growth factor (FGF-2), angiopoietin-1 (Ang-1), and insulin, which all activate the PI3K/Akt pathway, inhibited the release of sEng from endothelial cells. Inhibition of the PI3K/Akt pathway, by overexpression of phosphatase and tensin homolog (PTEN) or a dominant-negative isoform of Akt (Aktdn) induced sEng release from endothelial cells and prevented the inhibitory effect of VEGF-A. Conversely, overexpression of a constitutively active Akt (Aktmyr) inhibited PTEN and cytokine-induced sEng release. Systemic delivery of Aktmyr to mice significantly reduced circulating sEng, whereas Aktdn promoted sEng release. Phosphorylation of Akt was reduced in preeclamptic placenta and this correlated with the elevated level of circulating sEng. Knock-down of Akt using siRNA prevented HO-1-mediated inhibition of sEng release and reduced HO-1 expression. Furthermore, HO-1 null mice have reduced phosphorylated Akt in their organs and overexpression of Aktmyr failed to suppress the elevated levels of sEng detected in HO-1 null mice, indicating that HO-1 is required for the Akt-mediated inhibition of sEng. Conclusion - The loss of PI3K/Akt and/or HO-1 activity promotes sEng release and positive manipulation of these pathways offers a strategy to circumvent endothelial dysfunction.
