Прогноз контура нефтегазоносности нефтегазоконденсатного месторождения по комплексным геофизическим данным

Выпускная квалификационная работа состоит из 70 с. машинного печатного текста, 18 рис., 3 табл., 11 использованных источников. Объектом исследования является контур нефтегазоносности месторождения. Цель работы – определение контура нефтегазоносности при помощи данных сейсморазведочных, магниторазведочных, радиометрических работ. В процессе исследования проводилась интерпретация магниторазведочных, радиометрических работ; комплексирование площадных и скважинных методов исследований для прогноза контура нефтегазоносности как на уже выявленных бурением месторождениях, так и не вскрытых скважинами. Результатом исследования стали получение прогнозных карт контура нефтегазоносности разной вероятности, определение наиболее перспективных местоположений для разведочных скважин на изучаемой территоThe investigation consists of 70 pages printed text, 18 figures, 3 table, 11 soursed. Objective of investigation is contour of oil and gas on the field. Objective of investigation is determination the gas condensate field contour position using seismic, magnetic and radiometric surface data During the research they were interpreted seismic, magnetic and radiometric measurements, and then they were integrated with wells data to predict oil and gas contour on fields, which was identification by wells, and suppose fields without wells data. The conclusions of the investigation are the probability maps with different probability and determination optimal positions of the future exploration wells on the area

Molecular epidemiology of a nosocomial outbreak due to Enterobacter cloacae and Enterobacter agglomerans in Campinas, São Paulo, Brazil Epidemiologia molecular de um surto de bacteriemia por Enterobacter cloacae e Enterobacter agglomerans ocorrido na região de Campinas, São Paulo, Brasil

A total of 73 isolates (57 Enterobacter cloacae and 16 Enterobacter agglomerans), recovered during an outbreak of bacteremia in the Campinas area, São Paulo, Brazil, were studied. Of these isolates, 61 were from parenteral nutrition solutions, 9 from blood cultures, 2 from a sealed bottle of parenteral nutrition solution, and one was of unknown origin. Of the 57 E. cloacae isolates, 54 were biotype 26, two were biotype 66 and one was non-typable. Of 39 E. cloacae isolates submitted to ribotyping, 87.2% showed the same banding pattern after cleavage with EcoRI and BamHI. No important differences were observed in the antimicrobial susceptibility patterns among E. cloacae isolates exhibiting the same biotype, serotype and ribotype. All E. agglomerans isolates, irrespective of their origin, showed same patterns when cleaved with EcoRI and BamHI. The results of this investigation suggest an intrinsic contamination of parenteral nutrition solutions and incriminate these products as a vehicle of infection in this outbreak.<br>Foram estudadas um total de 73 cepas (57 de E. cloacae e 16 E. agglomerans), isoladas durante um surto de bacteriemia ocorrido na região de Campinas, S. Paulo. Entre estas cepas, 61 foram isoladas de solução de nutrição parenteral, 9 de sangue, 2 de bolsa fechada de solução de nutrição parenteral e uma era de origem desconhecida. Entre as 57 cepas de E. cloacae, a maioria das cepas foram do biotipo 26/sorotipo O3 (39 cepas) e do biotipo 26/OR (13). Entre as 39 cepas de E. cloacae ribotipadas, 87,2% apresentaram o mesmo padrão de bandas com EcoRI e BamHI. Cepas de E. cloacae pertencentes ao mesmo biotipo, sorotipo e ribotipo não apresentaram diferenças significativas em relação ao padrão de sensibilidade aos agentes antimicrobianos. Todas as cepas de E. agglomerans, independente da origem, pertenciam ao mesmo ribotipo após a clivagem com EcoRI e BamHI. Os resultados obtidos sugerem uma contaminação intrínseca das soluções de nutrição parenteral, incriminando-as como o veículo de transmissão dos agentes etiológicos do surto
