2000年6～11月对苏格兰拉姆岛上野化山羊（Caprahircus）种群的取食生态学进行了研究。研究表明：山羊的觅食回合长度变化范围从1min到460min不等，平均觅食回合长度是103．1±15．0（SD）min，雌性动物的觅食回合长度较雄性的长（P=0．077）。野化山羊单位时间的取食频率平均为46．3±0．6H／min，取食频率随性别（P=0．023）和月份（P〈0．001）而显著变化。雄性山羊在繁殖交配之前（6～7月）和之后（10～11月）的取食频率比繁殖交配期中（9～10月）的快（P〈0．008），但雌性动物并没有这样的变化（P=0．327）。雄性动物在繁殖交配期中的取食时间显著减少。雌、雄两性动物在取食频次和取食时间方面的这些差异可能导致该山羊种群在食物摄入量上的性别差异：雌性山羊的食物摄入量相对比较稳定，而雄性山羊的摄人量则变动很大。估计的食物摄人量随月份而下降（尽管9月份以后有一微小幅度的上升），这意味着拉姆岛上的山羊种群在食物匮乏而天气寒冷潮湿的冬季可能面临着能量收支不平衡的威胁。

Sediment yield dynamics on the Edwards Plateau region of Texas was dramatically influenced by a multi-year drought that occurred there during the 1950s. To assess the effect of this drought on sediment yield, we used the Soil and Water Assessment Tool (SWAT) to identify the factors that contributed erosion and to propose potential mitigation measures in case of future drought recurrence. The basins of interest to this study were Brady Creek One (BC 1) and Deep Creek Three (DC 3), located in mcCulloch County, Texas. Although the streams in these basins are not gauged, the land cover and reservoir sediment budgets have been assessed in a past study. Calibration of SWAT flow simulation was accomplished using parameter transfer from a gauging station located in San Saba River. The results showed that sediment yield from storms above 60 mm was five times more during and immediately after drought period than during continuous wet seasons. Approximately half of the total drought period sediment yield was from five major rainstorms. The multi-year drought coupled with historical high grazing intensity resulted in significant loss of plant cover, which was considered critical in determining erosion and sedimentation rates. To test this hypothesis, the model was run for the periods of high land cover (1990s) using the 1950s multi-year drought data which showed that sediment yield was 24% of that simulated for 1950s land cover. It was concluded that maintenance of surface cover could play a critical role associated with multi-year drought extreme events.

分子磁性材料是一类通过化学方法将自由基或顺磁离子及抗磁配体以自组装的方式组合而形成的分子水平的磁性化合物。在这其中,单分子磁体（Single-molecule magnets,Smms）尤其引人注目1-2,Smms是指在磁场下能被磁化,而当磁场撤去后仍能保持磁性的单个分子。由于在信息存储方面具有潜在的广泛的应用前景,Smms日益成为化学、材料物理等学科的研究热点。本文报道了一例氰基桥联的[FeⅢ4NiⅡ2]六核化合物,{[FeⅢ（Tp*）（CN）3]4[NiⅡ（tptz）]2}·meOH·nH2O（1）,我们通过X射线单晶衍射确定了化合物的结构,如图1a所示,更重要的是我们通过测量化合物的磁性性质（图1b是化合物的直流磁化率对温度的曲线）,成功观测到了缓慢磁驰豫现象,通过对其能垒的计算,可以认定化合物1是一例单分子磁体。

AIm To provide a "patient-normalized" parameter in the proximal forearm. mETHODS Sixty-three cadaveric upper extremities from thirty-five cadavers were studied. A muscle splitting approach was utilized to locate the posterior interosseous nerve(PIN) at the point where it emerges from beneath the supinator. The supinator was carefully incised to expose the midpoint length of the nerve as it passes into the forearm while preserving the associated fascial connections, thereby preserving the relationship of the nerve with the muscle. We measured the transepicondylar distance(TED), PIN distance in the forearm's neutral rotation position, pronation position, supination position, and the nerve width. Two individuals performed measurements using a digital caliper with inter-observer and intraobserver blinding. The results were analyzed with the Wilcoxon-mann-Whitney test for paired samples. RESULTS In pronation, the PIN was within two confidence intervals of 1.0 TED in 95% of cases(range 0.7-1.3 TED); in neutral, within two confidence intervals of 0.84 TED in 95% of cases(range 0.5-1.1 TED); in supination,within two confidence intervals of 0.72 TED in 95% of cases(range 0.5-0.9 TED). The mean PIN distance from the lateral epicondyle was 100% of TED in a pronated forearm, 84% in neutral, and 72% in supination. Predictive accuracy was highest in supination; in all cases the majority of specimens(90.47%-95.23%) are within 2 cm of the forearm position-specific percentage of TED. When comparing right to left sides for TEDs with the signed Wilcoxon-mann-Whitney test for paired samples as well as a significance test(with normal distribution), the P-value was 0.0357(significance-0.05) indicating a significant difference between the two *** This "patient normalized" parameter localizes the PIN crossing a line drawn between the lateral epicondyle and the radial styloid. Accurate PIN localization will aid in diagnosis, injections, and surgical approaches.
