O corpo e o templo : problemas sobre o uso do corpo na produção de um modelo comunitário ascético no cristianismo primitivo

O corpo no cristianismo primitivo não é apenas um dado biológico. É um princípio operativo sobre a qual se davam as práticas sociais e, ao mesmo tempo, os compromissos teológicos. O controle do corpo (e, daí, da sexualidade, da reprodução, das práticas ascéticas) era o ponto nevrálgico onde se deveria garantir não apenas a existência interna do grupo (sua continuação no tempo, suas hierarquias e suas diferenciações) mas também seus limites em relação ao meio circundante (o próprio e o impróprio, o puro e o impuro). Uma análise da ideologia do corpo no cristianismo primitivo pressupõe, antes de tudo, a manutenção do grupo, e tento mostrar de que modo ela não somente se beneficiava como se fundamentava na interpretação destas esferas: a das suas práticas sociais (a construção comunitária da moralidade) e a dos seus mecanismos teológicos (a criação de vínculos simbólicos, quer dizer, uma experiência e uma intelecção do que seria, para a grupo, a divindade).

Photodisintegration of helium-3 at energies between 200 and 600 MEV

We have measured differential cross-sections for the two-body photodisintegration of Helium-3, ɣ + He³ → p + d, between incident photon energies of 200 and 600 MeV, and for center of mass frame angles between 30° and 150°. Both final state particles were detected in arrays of wire spark chambers and scintillation counters; the high momentum particle was analyzed in a magnet spectrometer. The results are interpreted in terms of amplitudes to produce the ∆(1236) resonance in an intermediate state, as well as non-resonant amplitudes. This experiment, together with an (unfinished) experiment on the inverse reaction, p + d → He³ + ɣ, will provide a reciprocity test of time reversal invariance.

Ecos da fé na alma e na obra de Eça de Queiróz:uma visão crítica da Igreja e da Religião Católicas no século XIX

Esta dissertação, inserida na linha de pesquisa de Política e Cultura, trata da visão crítica de Eça de Queiroz sobre a Igreja Católica, sobre o catolicismo popular e a relação Igreja-Estado em Portugal do século XIX. O trabalho aprofunda as idéias do autor estabelecidas no momento histórico do chamado movimento da Regeneração, na segunda metade do século, marcado por propostas de denúncias da decadência da sociedade e de mudanças e reformas modernizantes nas estruturas econômicas, sociais, políticas educacionais e culturais do país. Analisa questões relevantes ligadas à política da época como o liberalismo monárquico, a política do estado constitucional português, a política ultramontana do Vaticano e seus desdobramentos em Portugal, além do catolicismo institucionalizado nas práticas políticas e culturais. A partir de fontes primárias como os trabalhos jornalísticos do autor, publicados no Brasil e em Portugal, assim como cartas para seus amigos intelectuais da chamada Geração 70, aborda questões como o anticlericalismo, antijesuitismo, Padroado, regalismo e o projeto cultural português de secularização. Observando o extremo espírito perspicaz e sarcástico do autor, o trabalho conclui por entender o escritor como forte defensor de reformas nas práticas, discursos e preocupações da Igreja Católica de seu tempo, assim como voz exigente e consonante a outros intelectuais da época em prol de novo comprometimento e atuação dessa mesma Igreja. Por fim, estabelece o autor como um expoente entre a intelectualidade por ser protagonista de um movimento de renovação política e cultural, como catalisador da opinião pública de seu tempo, e acima de tudo, autor de uma obra de relevância literária e jornalística, capaz de impor-se como efetiva proposta inovadora para a modernidade portuguesa da época.

Representação Social da Igreja Universal do Reino de Deus por evangélicos dela egressos

A Igreja Universal do Reino de Deus (IURD) foi fundada há trinta e quatro anos e tem forte influência social e política. Sua capilaridade religiosa se expressa através da sua inserção em diversas mídias, como TV, rádio, jornal etc. e da participação política evidenciada pelas "bancadas evangélicas" nos diferentes parlamentos, onde predominam autoridades da IURD. Também se faz presente através dos milhares de templos construídos e espalhados por mais de 180 países. Sua estratégia de proselitismo religioso é baseada na conversão de adeptos de outras religiões. Sua hierarquia: obreiros, pastores e bispos, define a igreja como o maior "pronto-socorro" espiritual do Brasil. Caracterizada pelo oferecimento de solução de problemas imediatos e de natureza espiritual. Após algum tempo, conversos da IURD migram para outras igrejas evangélicas. O objetivo desta pesquisa foi identificar as Representações Sociais da IURD segundo evangélicos dela egressos. Para tanto, foram entrevistados vinte indivíduos adultos, na Cidade do Rio de Janeiro, egressos da IURD. Como instrumento, utilizamos um questionário para entrevista semi-estruturada, composto por questões acerca da IURD e dados pessoais do entrevistado. O material resultante foi analisado a partir da análise de conteúdo. As entrevistas foram gravadas, com a autorização dos entrevistados e o comprometimento na manutenção do anonimato dos participantes. Dentre os resultados da pesquisa, confirmando o que é dito por seus líderes, encontramos a IURD como um pronto socorro, não só espiritual, como emocional e de saúde física. A migração da IURD para outras denominações cristãs está associada a três grandes categorias: a) o sujeito não tem mais necessidade do pronto-socorro; b) crítica às cobranças sistemáticas por bens espirituais; c) a necessidade de aprofundamento religioso. Neste aspecto, a IURD caracteriza-se por ser uma Igreja de transição, de início de vida espiritual cristã e de proselitismo voltado quase que exclusivamente para a conversão.

Implications of using On-Farm Flood Flow Capture to recharge groundwater and mitigate flood risks along the Kings River, CA

Two large hydrologic issues face the Kings Basin, severe and chronic overdraft of about 0.16M ac-ft annually, and flood risks along the Kings River and the downstream San Joaquin River. Since 1983, these floods have caused over $1B in damage in today’s dollars. Capturing flood flows of sufficient volume could help address these two pressing issues which are relevant to many regions of the Central Valley and will only be exacerbated with climate change. However, the Kings River has high variability associated with flow magnitudes which suggests that standard engineering approaches and acquisition of sufficient acreage through purchase and easements to capture and recharge flood waters would not be cost effective. An alternative approach investigated in this study, termed On-Farm Flood Flow Capture, involved leveraging large areas of private farmland to capture flood flows for both direct and in lieu recharge. This study investigated the technical and logistical feasibility of best management practices (BMPs) associated with On-Farm Flood Flow Capture. The investigation was conducted near Helm, CA, about 20 miles west of Fresno, CA. The experimental design identified a coordinated plan to determine infiltration rates for different soil series and different crops; develop a water budget for water applied throughout the program and estimate direct and in lieu recharge; provide a preliminary assessment of potential water quality impacts; assess logistical issues associated with implementation; and provide an economic summary of the program. At check locations, we measured average infiltration rates of 4.2 in/d for all fields and noted that infiltration rates decreased asymptotically over time to about 2 – 2.5 in/d. Rates did not differ significantly between the different crops and soils tested, but were found to be about an order of magnitude higher in one field. At a 2.5 in/d infiltration rate, 100 acres are required to infiltrate 10 CFS of captured flood flows. Water quality of applied flood flows from the Kings River had concentrations of COC (constituents of concern; i.e. nitrate, electrical conductivity or EC, phosphate, ammonium, total dissolved solids or TDS) one order of magnitude or more lower than for pumped groundwater at Terranova Ranch and similarly for a broader survey of regional groundwater. Applied flood flows flushed the root zone and upper vadose zone of nitrate and salts, leading to much lower EC and nitrate concentrations to a depth of 8 feet when compared to fields in which more limited flood flows were applied or for which drip irrigation with groundwater was the sole water source. In demonstrating this technology on the farm, approximately 3,100 ac-ft was diverted, primarily from April through mid-July, with about 70% towards in lieu and 30% towards direct recharge. Substantial flood flow volumes were applied to alfalfa, wine grapes and pistachio fields. A subset of those fields, primarily wine grapes and pistachios, were used primarily to demonstrate direct recharge. For those fields about 50 – 75% of water applied was calculated going to direct recharge. Data from the check studies suggests more flood flows could have been applied and infiltrated, effectively driving up the amount of water towards direct recharge. Costs to capture flood flows for in lieu and direct recharge for this project were low compared to recharge costs for other nearby systems and in comparison to irrigating with groundwater. Moreover, the potentially high flood capture capacity of this project suggests significant flood avoidance costs savings to downstream communities along the Kings and San Joaquin Rivers. Our analyses for Terranova Ranch suggest that allocating 25% or more flood flow water towards in lieu recharge and the rest toward direct recharge will result in an economically sustainable recharge approach paid through savings from reduced groundwater pumping. Two important issues need further consideration. First, these practices are likely to leach legacy salts and nitrates from the unsaturated zone into groundwater. We develop a conceptual model of EC movement through the unsaturated zone and estimated through mass balance calculations that approximately 10 kilograms per square meter of salts will be flushed into the groundwater through displacing 12 cubic meters per square meter of unsaturated zone pore water. This flux would increase groundwater salinity but an equivalent amount of water added subsequently is predicted as needed to return to current groundwater salinity levels. All subsequent flood flow capture and recharge is expected to further decrease groundwater salinity levels. Second, the project identified important farm-scale logistical issues including irrigator training; developing cropping plans to integrate farming and recharge activities; upgrading conveyance; and quantifying results. Regional logistical issues also exist related to conveyance, integration with agricultural management, economics, required acreage and Operation and Maintenance (O&M).

On the acid-base stability of Keggin Al-13 and Al-30 polymers in polyaluminum coagulants

The acid-base stabilities of Al-13 and Al-30 in polyaluminum coagulants during aging and after dosing into water were studied systematically using batch and flow-through acid-base titration experiments. The acid decomposition rates of both Al-13 and Al-30 increase rapidly with the decrease in solution pH. The acid decompositions of Al-13 and Al-30 with respect to H+ concentration are composed of two parallel first-order and second-order reactions, and the reaction orders are 1.169 and 1.005, respectively. The acid decomposition rates of Al-13 and Al-30 increase slightly when the temperature increases from 20 to ca. 35 A degrees C, but decrease when the temperature increases further. Al-30 is more stable than Al-13 in acidic solution, and the stability difference increases as the pH decreases. Al-30 is more possible to become the dominant species in polyaluminum coagulants than Al-13. The acid catalyzed decomposition and followed by recrystallization to form bayerite is one of the main processes that are responsible for the decrease of Al-13 and Al-30 in polyaluminum coagulants during storage. The deprotonation and polymerization of Al-13 and Al-30 depend on solution pH. The hydrolysis products are positively charged, and consist mainly of repeated Al-13 and Al-30 units rather than amorphous Al(OH)(3) precipitates. Al-30 is less stable than Al-13 upon alkaline hydrolysis. Al-13 is stable at pH < 5.9, while Al-30 lose one proton at the pH 4.6-5.75. Al-13 and Al-30 lose respective 5 and 10 protons and form [Al-13] (n) and [Al-30] (n) clusters within the pH region of 5.9-6.25 and 5.75-6.65, respectively. This indicates that Al-30 is easier to aggregate than Al-13 at the acidic side, but [Al-13] (n) is much easier to convert to Alsol-gel than [Al-30] (n) . Al-30 possesses better characteristics than Al-13 when used as coagulant because the hydrolysis products of Al-30 possess higher charges than that of Al-13, and [Al-30] (n) clusters exist within a wider pH range.

Preparation of Pb-Ca-Na master alloy using molten chloride salt electrolysis

An electrolysis technique for co-deposition of Ca2+ and Na+ at the liquid lead cathode was put forward. The experiment was carried out at an electrolysis temperature below 650 degrees C and had a current efficiency of 98%, which are respectively 100 similar to 300 degrees C lower and 15% similar to 30% higher than those reported both at home and abroad.

THE EFFECT ON PHYSICAL-PROPERTIES OF THE SUBSTITUTION OF CA OR BA FOR SR IN NDSRNIO4

A new solid solution series, NdSr(1-x)M(x)NiO(4) (M = Ca: 0.0 less than or equal to x less than or equal to 1.0; M = Ba: 0.0 less than or equal to x less than or equal to 0.6), was synthesized by solid state reaction, and the structures, magnetic and electrical properties and optical spectra of this series have been studied. All the samples crystalized in tetragonal systems, with the exception of NdCaNiO4, which crystallized in the orthohombic system. IR spectra of NdSr1-xCaxNiO4 indicated that the lengths of two Ni-O bonds decrease with increasing Ca content. The electrical conduction changed from metallic-type to semiconductive-type when x greater than or equal to 0.4 (M = Ca, Ba), and the room temperature resistivities of NdSr1-xCaxNiO4 increased with the increase of Ca content. Magnetic susceptibility measurements revealed that Ni+3 ions in all the samplies were in low-spin state over the temperature range 77-300 K.

Carbachol triggers RyR-dependent Ca(2+) release via activation of IP(3) receptors in isolated rat gastric myocytes.

Possible interactions between different intracellular Ca(2+) release channels were studied in isolated rat gastric myocytes using agonist-evoked Ca(2+) signals. Spontaneous, local Ca(2+) transients were observed in fluo-4-loaded cells with linescan confocal imaging. These were blocked by ryanodine (100 microM) but not by the inositol 1,4,5-trisphosphate receptor (IP(3)R) blocker, 2-aminoethoxydiphenyl borate (100 microM), identifying them as Ca(2+) sparks. Caffeine (10 mM) and carbachol (10 microM) initiated Ca(2+) release at sites which co-localized with each other and with any Ca(2+) spark sites. In fura-2-loaded cells extracellular 2-aminoethoxydiphenyl borate and intracellular heparin (5 mg ml(-1)) both inhibited the global cytoplasmic [Ca(2+)] transient evoked by carbachol, confirming that it was IP(3)R-dependent. 2-Aminoethoxydiphenyl borate and heparin also increased the response to caffeine. This probably reflected an increased Ca(2+) store content since 2-aminoethoxydiphenyl borate more than doubled the amplitude of transients evoked by ionomycin. Ryanodine completely abolished carbachol and caffeine responses but only reduced ionomycin transients by 30 %, suggesting that blockade of carbachol transients by ryanodine was not simply due to store depletion. Double labelling of IP(3)Rs and RyRs demonstrated extensive overlap in their distribution. These results suggest that carbachol stimulates Ca(2+) release through co-operation between IP(3)Rs and RyRs, and implicate IP(3)Rs in the regulation of Ca(2+) store content.
