Molecular recognition with C-clamp porphyrins: synthesis, structural, and complexation studies

The cholesterolaemic effect of 2 hypercholesterolaemic diets was tested in 12 rat inbred strains. Diet I is a commercial diet supplemented with 2.0% (w/w) cholesterol and 5.0% (w/w) olive oil; diet II is identical to diet I with addition of 0.5% (w/w) sodium cholate. Strains with the highest plasma cholesterol response after diet I (BN and LEW) also had the highest cholesterol response after diet II (hyperresponders, mean response > 3.5 mmol/l). In the strains DA, SHR, BC, WAG, LOU, PVG and BUF the strain mean cholesterol response remained below 1.3 mmol/l after both diets (hyporesponders). Strains F344 and OM had an intermediate cholesterol response after both diets (normoresponders, mean response between 1.3 and 3.5 mmol/l). Only in the strains LOU, PVG and SHR there appeared to be a significant higher cholesterol response after diet II when compared with the cholesterol response after diet I. In the strain WKY this difference was of a borderline significance (P = 0.052) and this strain turned from a normoresponder after diet I into a hyperresponder after diet II. Liver cholesterol levels as measured after feeding diet II for two weeks also appeared to be strain-specific. No correlation was found between the plasma cholesterol response after diet II and the liver cholesterol levels. Changes in plasma phospholipid and triglyceride levels have been measured for both diet I and diet II. For group means a correlation between the cholesterol response and the change in phospholipid levels was found (r = 0.86 for diet I, P < 0.001 and r = 0.76 for diet II, P < 0.01). No such correlation was found for triglyceride levels.     

模拟光耦SLC800在转台系统中的应用

在大功率转台控制系统中．存在着较大的电压干扰和电磁兼容问题。在转台的控制精度和驱动功率不断提高的情况下．本文使用模拟光耦隔离器件SLC800重新设计了转台中的某部分模拟电路．将功率放大电路和控制电路隔开，来增强系统的抗干扰能力和运行的可靠性。实验结果的分析和转台的运行表明：应用模拟光耦进行隔离，有效地消除了转台控制中的干扰和电磁兼容。     

用层次分析法(AHP)确定QFD中客户需求权重

客户需求权重的确定是质量功能配置(QFD)实现过程中的重要一环，然而传统的确定权重的方法都有各自的缺陷。本文采用层次分析法(AHP)来确定客户需求的权重，首先建立了评价模型，并构造出比较判断矩阵，然后通过层次排序和一致性检验，最终获得了接近实际的客户需求权重结果。文章最后以某企业所生产的车床的客户需求为例，验证了用AHP法来确定QFD中客户需求权重的可行性。     

河道维护费征收中需注意的几个问题

依法征收河道工程维护费,是水行政主管部门的一项重要职能,是强化水利依法管理的重要手段和筹措水利建设资金的重要途径。随着依法行政进程的不断推进,被征管单位依法维权的意识不断增强。根据《行政诉讼法》的规定,人民法院审查行政案件,对具体行政行为是否合法进行审查。根据《行政复议法》的规定,复议机关审查复议案件,对具体行政行为是否合法
