AIM: To compare outcomes between single and dual en bloc(EB) kidney transplants(KT) from small pediatric donors. METHOdS: Monocentric nonprospective review of KTs from pediatric donors ≤ 5 years of age. dual EB KT was defined as keeping both donor kidneys attached tothe inferior vena cava and aorta, which were then used as venous and arterial conduits for the subsequent transplant into a single recipient. donor age was less useful than either donor weight or kidney size in decision-making for kidney utilization as kidneys from donors dneys d. Post-transplant management strategies were standardized in all ***: From 2002-2015, 59 KTs were performed including 34 dual EB and 25 single KTs. Mean age of donors(17 mo vs 38 mo, P d male donors(50% vs 84%, P = 0.01) were lower in the dual EB compared to the single KT group, respectively. Mean cold ischemia time(21 h), kidney donor profile index(KdPI; 73% vs 62%) and levels of serum creatinine(SCr, 0.37 mg/d L vs 0.49 mg/d L, all P = NS) were comparable in the dual EB and single KT groups, respectively. Actuarial graft and patient survival rates at 5-years follow-up were comparable. There was one case of thrombosis resulting in graft loss in each group. delayed graft function incidence(12% dual EB vs 20% single KT, P = NS) was slightly lower in dual EB KT recipients. Initial duration of hospital stay(mean 5.4 d vs 5.6 d) and the one-year incidences of acute rejection(6% vs 16%), operative complications(3% vs 4%), and major infection were comparable in the dual EB and single KT groups, respectively(all P = NS). Mean 12 mo SCr and abbreviated MdRd levels were 1.17 mg/d L vs 1.35 mg/d L and 72.5 m L/min per 1.73 m^2 vs 60.5 m L/min per 1.73 m^2(both P = NS) in the dual EB and single KT groups, respectively. CONCLUSION: By transplanting kidneys from young pediatric donors into adult recipients, one can effectively

油藏工程的主要工作就是开发和管理油田 ,用最小成本提高产量或最终储量 ,以此来增大一个油田的盈利能力。世界上许多水平井项目的完成情况都表明 ,水平井能够有效地实现这一目的 ,海上油田的水平井更是如此。然而 ,油井动态是众多参数共同影响的结果 ,因此水平井和油层的相互干扰使得油井动态更为复杂。本文通过油藏数值模拟来预测产量 ,拟在提出一种自动方法论 ,该方法可以使油田应用水平井技术实现动态最优化。方法论是通过对单井、井组和油田动态分析而发展起来的 ,其目的是确定能够解释水平井生产能力的参数、进行油井动态比较、分析导致油田和油井动态差的原因。分析的基础是精选的目标函数 :净现值、累计产油量、累计产气量、累计产水量和累计注水量。本文还采用了允许同时变化的油井周边概念。

随着塔中地区下古生界碳酸盐岩油气勘探地持续深入,分别在野外露头,塔中地区相关探井奥陶系储层中发现有萤石、闪锌矿、天青石、重晶石、硬石膏、焦沥青及热液石英等一系列热液矿物及其组合,越来越多的地质资料表明热液岩溶储层可能是塔里木盆地下古生界碳酸盐岩油气勘探中被忽视的一个重要储层类型。通过总结近6年大量的针对野外露头热液岩溶现象地实地观察测量,以及通过对塔中82井区—24井区奥陶系储层发育段大量的岩石薄片观察、矿物能谱测定、地层水锶同位素测试,断裂性质的分析,深入研究热液溶蚀流体的活动特点以及对形成优质储层的控制作用,最终建立了热液岩溶储层的地质模型。研究表明,热液矿物主要沿断裂伴生的构造溶蚀缝和溶蚀孔洞发育,断裂是热液运移的主要通道,是形成优质储层的重要控制因素。塔中地区沿海西期走滑断裂附近的奥陶系灰岩将广泛发育热液溶蚀改造形成的储层,为塔中西部上奥陶统沿走滑断裂向内带拓展油气勘探打下了基础。

In the fall of 2016, a field study was conducted in the Uinta Basin Utah to improve information on oil and natural gas well pad pneumatic controllers (PCs) and emission measurement methods. A total of 80 PC systems at five oil sites (supporting six wells) and three gas sites (supporting 12 wells) were surveyed, and emissions data were produced using a combination of measurements and engineering emission estimates. Ninety-six percent of the PCs surveyed were low actuation frequency intermittent vent type. The overall whole gas emission rate for the study was estimated at 0.36 scf/h with the majority of emissions occurring from three continuous vent PCs (1.1 scf/h average) and eleven (14%) malfunctioning intermittent vent PC systems (1.6 scf/h average). Oil sites employed, on average 10.3 PC systems per well compared to 1.5 for gas sites. Oil and gas sites had group average PC emission rates of 0.28 scf/h and 0.67 scf/h, respectively. This difference was due in part to differing site selection procedures used for oil and gas sites. The PC system types encountered, the engineering emissions estimate approach, and comparisons to measurements are described. Survey methods included identification of malfunctioning PC systems and emission measurements with augmented high volume sampling and installed mass flow meters, each providing a somewhat different representation of emissions that are elucidated through example cases.

This study focuses on the geochemical and bacteriological investigation of surface and ground water in the Bamoun plateau (Western-Cameroon). during the period from September 2013 to August 2014, 71 samples were collected from two springs, one borehole, four wells and the Nchi stream for analysis of major elements. In order to obtain the characteristics of the various species of bacteria, 7 samples were selected. The analytical method adopted for this study is the conventional hydrochemical technic and multivariate statistical analysis, coupled with the hydrogeochemical modelling. The results revealed that, water from the zone under study are acidic to basic, very weakly to weakly mineralized. Four types of water were identified: 1) CaMg-HCO3;2) CaMg-Cl-SO4;3) NaCl-SO4 and 4) NaK-HCO3. The major elements were all listed in the World Health Organization guidelines for drinking water quality, except for nitrates which was found at a concentration > 50 mg /l NO-3 in the borehole F401. As for the hydrobiological aspect, the entire sample contained all the bacteriological species except for spring S301 and well P401. According to the hydrogeochemical modelling, the Gibbs model and multivariate statistical tests, the quality of surface and ground water of the Foumban locality is influenced by two important factors: 1) the natural factors characterized by the water-rock interaction, evapotranspiration/crystallization, 2) the anthropogenic factors such as: uncontrolled discharges of liquid and solid effluents of all kinds and without any prior treatment within the ground and the strong urbanization accompanied by lack of sanitation and insufficient care.
