Electrical Impedance Tomography (EIT) is a medical imaging technique which can be used to monitor the regional ventilation in patients utilizing voltage measurements made at the thorax. Several reconstruction algorithms have been developed during the last few years. In this manuscript we compare a well-established algorithm and a re-cently developed method for image reconstruction regarding EIT indices derived from the differently reconstructed images.

目的了解目前中国农村地区成人乙肝疫苗接种情况,探讨成人乙肝疫苗接种行为的影响因素,为医改后继续深化乙肝防治提供依据。方法于2011年3—7月采用多阶段与概率比例规模(PPS)抽样结合的方法,抽取宁夏、河北、山东、江苏4个省7个县市23个村12 499名≥18岁农村居民,对其乙肝疫苗接种情况及主要影响因素进行问卷调查。结果 4省农村成人中乙肝疫苗接种率为13.89%(1 736/12 499),全程接种率为11.02%(1 378/12 499),接种人群中全程接种率为79.38%(1 378/1 736);多分类有序logistic回归分析结果表明,年龄越大,乙肝疫苗接种针次越少;人均年收入越高、乙肝认知越好、对乙肝疫苗的信任度越高、威胁评估越高、文化程度越高,乙肝疫苗接种针次越多;农民和打工者乙肝疫苗接种针次较少。结论年龄、职业、文化程度、经济原因和对乙肝防治知识及疫苗的认识不足是农村成人乙肝疫苗接种行为的主要影响因素。

与中枢神经系统的空间结构高度一致,大部分的中枢神经系统疾病表现为区域性分布。虽然小胶质细胞已被公认在各种中枢神经系统疾病中发挥重要的作用,但是小胶质细胞是否表现为区域特异性目前还不清楚。因此,本研究目的是评估在健康成年小鼠的中枢神经系统的不同区域中小胶质细胞的不同表型。运用体外流式细胞仪分析CD11b,CD40,CD45,CD80,CD86,F4/80,TREM-2b,MHCII,CXCR3,CCR9以及CCR7的表面表达。这些免疫调节标记物大部分均存在于小胶质细胞上并且在表达水平上有明显的区域特异性差异。这些发现在很大程度上证实了在健康成年小鼠中枢神经系统的小胶质细胞中存在着免疫多样性。

沉积学报 2000年第1期18卷 119-126页

作者： Shao nan Zhang 1 knut Bj Φ rlykke 2 1 (Chengdu University of Technology Chengdu 610059) 2 (Department of Geology Box 1047 University of Oslo 0316 Oslo 3 Norway) 成都理工学院四川成都 610059 University of Oslo 挪威 Oslo3 0316

The timing and duration of quartz cementation in sandstones have been mainly inferred from diagenetic texture, relationship between pore filling minerals, fluid inclusions and isotopic data. Fluid inclusion temperatures from North Sea reservoir sandstones indicate that most of the quartz cement forms at temperature exceeding 90℃ and is continually proceeding after oil emplacement, based on the fluid inclusion temperatures in quartz overgrowth which is approaching the bottom-hole temperatures. The duration of quartz cement after oil emplacement depends upon the saturation of porewater and the distribution of pore water film and the property of water-wet or oil-wet of the reactants. The leaching of K-feldspar by meteoric water requires pore water flow to move the released potassium and sodium and silica out the solution, which suggests the mechanism does not appear to be a major source of silica for quartz cementation. The quartz cementation coincidence with the compaction and pressure solution suggests the major source of silica. The alteration of feldspar by illitization of kaolinite may serve as another important source of silica at deep burial depth. External sources are not need to call on for illustrating the quartz cementation, because there is no evidences for large scale convection of pore water flow occurred in the burial history of reservoir sandstones of middle Jurassic in the North Sea.

The development of methods to produce nanoparticles with unique properties via the aerosol route is progressing rapidly. Typical characterization techniques extract particles from the synthesis process for subsequent offiine analysis, which may alter the particle characteristics. In this work, we use laser-vaporization aerosol mass spectrometry （LV-AMS） with 70-eV electron ionization for real-time, in-situ nanoparticle characterization. The particle characteristics are examined for various aerosol synthesis methods, degrees of sintering, and for controlled condensation of organic material to simulate surface coating/functionalization. The LV-AMS is used to characterize several types of metal nanoparticles （Ag, Au, Pd, PdAg, Fe, Ni, and Cu）. The degree of oxidation of the Fe and Ni nanoparticles is found to increase with increased sintering temperature, while the surface organic-impurity content of the metal particles decreases with increased sintering temperature. For aggregate metal particles, the organic-impurity content is found to be similar to that of a monolayer. By comparing different equivalent-diameter measurements, we demonstrate that the LV-AMS can be used in tandem with a differential mobility analyzer to determine the compactness of synthesized metal particles, both during sintering and during material addition for surface functionalization. Further, materials supplied to the particle production line downstream of the particle generators are found to reach the generators as contaminants. The capacity for such in-situ observations is important, as it facilitates rapid response to undesired behavior within the particle production process. This study demonstrates the utility of real-time, in-situ aerosol mass spectrometric measurements to characterize metal nanoparticles obtained directly from the synthesis process line, including their chemical composition, shape, and contamination, providing the potential for effective optimization of process operating p
