摘要： 在道路交通事故中，有时会出现汽车驾驶室内司乘人员全部被抛出车外死亡的情况。在这种情况下，对驾驶员的确认关系到确定事故责任和赔偿的主体，非常重要。 现介绍一例经过广泛调查，了解到拯救车驾驶室内司乘人员发生事故之前的饮食情况，通过检验胃内容来确认驾驶员的案例。 一、案情简介 １９９９年５月１３日２３：００时，１０７国道广州市白云区一客运站附近，南北走向双向四车道路段，粤Ａ．１００９１号拯救车，从路东客运站驶出，准备左转弯向南行驶。在横过公路时和一辆向北行驶的大货车发生碰撞。之后两车车头向西并排而停，大货车完全驶出路面，拯救车尚有部分留在路面内。 二、事故现场 拯救车上三人均被抛出车外。梁××被拯救车左后轮碾压当场死亡，尸体仰面躺在拯救车左后轮后，头向南。严××被压在大货车右后轮处，沈××倒在大货车后面偏西南的路面内，二人经抢救无效死亡。 拯救车左侧车门呈１５０”～１６０ｏ向前打开，右侧车门关闭，前面和左右两侧挡风玻璃无破裂。拯救车驾驶室内部收放机旋钮，驻车制动拉索拉杆把手、变速杆把手均变形或断裂，向左侧倾斜移位，应是发生碰撞时，三人抛出车外所造成。 驾驶室内经检查没有发现血迹、痕迹和遗留物。 三、法医检验 沈ｘＸ...

摘要： Macroinvertebrate biological monitoring in Victoria, Australia, has required substantial resources over the past decade, and often results have taken years to reach water managers. Ways of reducing the time and effort required in this program were examined. The influence of taxonomic resolution and sample habitat on the classification and ordination of 165 stream sites in 27 catchments across Victoria was examined by progressively reducing the level of detail in the original data. Macroinvertebrate samples were collected from 2 habitats (riffle and edge) at each site. A 3rd data set was generated by amalgamating the individual habitats. These 3 habitat treatments were analyzed at family, genus, and species level, and a 4th taxonomic treatment was generated at species level including Ephemeroptera, Plecoptera, and Trichoptera (EPT) taxa only. All 12 data sets were analyzed using presence/absence data, and each was used to classify sites across Victoria into groups that were characterized using environmental variables. The Mantel test was used to compare the 12 analyses, and showed that each of the analyses produced similar patterns. A number of possible ways to reduce time and effort in broad-scale macroinvertebrate studies were evident: 1) single habitat sampling was sufficient for biological monitoring, 2) studies that require species-level discrimination may be able to reduce costs by identifying EPT taxa only, and 3) genus-level identifications offered no substantial advantage over family-level identifications. Overall, species-level identification appeared to be unnecessary for broad-scale monitoring programs and, in future, taxonomic effort could be reduced by identifying to family level only.

摘要： The eukaryotic chaperonin tailless complex polypeptide 1 (TCP1) ring complex (TRiC) (also called chaperonin containing TCP1 [CCT]) is a hetero-oligomeric complex that facilitates the proper folding of many cellular proteins. To better understand the manner in which TRiC interacts with newly translated polypeptides, we examined its association with nascent chains using a photo-cross-linking approach. To this end, a series of ribosome-bound nascent chains of defined lengths was prepared using truncated mRNAs, Photoactivatable probes were incorporated into these S-35- labeled nascent chains during translation. Upon photolysis, TRiC was cross-linked to ribosome-bound polypeptides exposing at least 50-90 amino acids outside the ribosomal exit channel, indicating that the chaperonin associates with much shorter nascent chains than indicated by previous studies. Cross-links were observed for nascent chains of the cytosolic proteins actin, luciferase, and enolase, but not to ribosome-bound preprolactin. The pattern of cross-links became more complex as the nascent chain increased in length,These results suggest a chain length-dependent increase in the number of TRiC subunits involved in the interaction that is consistent with the idea that the substrate participates in subunit-specific contacts with the chaperonin. Both ribosome isolation by centrifugation through sucrose cushions and immunoprecipitation with antipuromycin antibodies demonstrated that the photoadducts form on ribosome-bound polypeptides. Our results indicate that TRiC/CCT associates with the translating poly-peptide shortly after it emerges from the ribosome and suggest a close association between the chaperonin and the translational apparatus.

摘要： 1.合同的形式。合同法第一百九十七条规定:“借款合同采用书面形式,但自然人之间的借款另有约定的除外。”也就是说,个人之间的借款既可以采用书面形式,也可以采用口头约定的形式。 2.合同生效的时间。个人之间借款的合同是实践合同,仅有双方当事人的合意合同还不能成立,必须要有实际的交付行为,即合同是在贷款人提供借款时生效。因此。

摘要： Isothermal titration calorimetry was used to examine the energetics of surfactant aggregation in the absence and presence of hydrophobically modified alkali-soluble emulsion (HASE) polymers. The binding behavior of SDS onto several model HASE polymers with C-1, C-8, C-12, C-16, and C-20 hydrophobes was investigated. A 0.1 wt % HASE polymer solution was titrated with a 0.1M SDS solution. For all the SDS/polymer systems, pronounced endothermic differential enthalpic curves are observed. Thermodynamic parameters such as enthalpy and entropy change of aggregation confirm that the process for the binding of SDS to the hydrophobic junction is entropy-driven. The Gibbs energy of binding of SDS onto the model polymers increases from -2.9 kJ/mol for C-1 hydrophobe to -4.2 kJ/mol for C-20 hydrophobes. The critical aggregation concentration and the negative enthalpy of aggregation decrease with increasing polymer hydrophobicity.
