俄国割占黑龙江、乌苏里江地区后当地华人商业的形成和发展

黑龙江以北、乌苏里江以东百万平方公里的土地按照中俄《瑷珲务约》和中俄《北京条约》正式划归俄国后，为了在这一新占领地区站稳脚跟，俄国政府不但对居住在这一地区的中国人采取了宽容的策略，而且极力开展没有任何限制和监控的自由贸易。于是，中国人在当地的商业开始形成规模并迅速发展。     

河北省农村最低生活保障制度现状分析

明清州县监狱狱囚生活处遇制度研究

狱囚的生活处遇是监狱管理的一项重要内容，与前代相比，明清时期，州县监狱在狱囚生活处遇方面的制度和法规都有了明显进步，达到了相当完善的程度，但是，这些制度与规定在许多时候都不能得到切实的执行，狱囚的生活仍然相当悲惨。这表明，在古代社会，狱囚的生活处遇制度并不意味着承认囚犯的人权，而是为了体现统治者的仁厚，狱囚生活处遇的实际情况很大程度上受制于政治的清明程度，这使狱囚的生活待遇缺乏稳定性和保障。     

发展小城镇是提高我国城市化水平的重要途径

发展小城镇 ,提高城市化水平 ,是促进我国国民经济发展的重要举措。城市化水平的滞后影响了消费需求正常增长 ,导致了三次产业结构失衡 ,限制了乡镇工业的发展 ,影响了我国经济市场化的进程。小城镇将在我国城市体系中起到不可替代的地位和作用 ,发展小城镇才能有效地解决农村剩余劳动力向非农产业转移 ,避免大城市病 ,实现充分就业 ,它是符合我国实际的城市化发展的一条独特之路     

羊毛皮张和土壤中炭疽杆菌PCR检测方法的建立

建立了检测炭疽芽孢杆菌染色体特异性基因序列 (Ba813)的PCR技术 ,并用于模拟污染的羊毛、皮张和土壤中炭疽芽孢 (Sterne菌株、PasteurⅡ菌株 )的检测。结果表明 ,该方法可特异、敏感地检出 0 .5 g羊毛中Sterne菌株的 4 5 2个芽孢和PasteurⅡ菌株的 6 88个芽孢 ;0 .5g皮张中Sterne菌株的 4 5 2个芽孢和PasteurⅡ菌株的 10 32个芽孢 ;0 .5 g土壤中Sterne菌株的 4 5 2个芽孢和PasteurⅡ菌株 1376个芽孢。证实PCR可用于羊毛、皮张和土壤等外环境中炭疽杆菌芽孢的检测。     

Understanding Variations of Soil Mapping Units and Associated Data for Forensic Science

Soil samples have potential to be useful in forensic investigations, but their utility may be limited due to the inherent variability of soil properties, the wide array of analytical methods, and complexity of data analysis. This study examined the differentiation of similar soils based on both gross (texture, color, mineralogy) and explicit soil properties (elemental composition, cation exchange, Fe‐oxyhydroxides). Soils were collected from Fallbrook and adjacent map units from Riverside and San Diego Counties in California. Samples were characterized using multiple techniques, including chemical extracts, X‐ray diffraction (XRD), and Fourier transform infrared spectroscopy. Results were analyzed using multiple analytical approaches to compare counties and land uses. Some analyses (XRD, extractions) were better at distinguishing among samples than others (color, texture). Ratios of rare earth elements were particularly useful for distinguishing samples between counties. This potential to “fingerprint” soils illustrates the usefulness of a comprehensive soil database for criminal investigators.     

Investigating the Postmortem Molecular Biology of Cartilage and its Potential Forensic Applications

This study investigated the postmortem molecular changes that articular cartilage undergoes following burial. Fresh pig trotters were interred in 30‐cm‐deep graves at two distinct locations exhibiting dissimilar soil environments for up to 42 days. Extracts of the metacarpophalangeal (MCP) and metatarsophalangeal (MTP) joint cartilage from trotters disinterred weekly over 6 weeks were analyzed by Western blot against the monoclonal antibody 2‐B‐6 to assess aggrecan degradation. In both soil conditions, aggrecan degradation by‐products of decreasing molecular size and complexity were observed up to 21 days postmortem. Degradation products were undetected after this time and coincided with MCP/MTP joint exposure to the soil environment. These results show that cartilage proteoglycans undergo an ordered molecular breakdown, the analysis of which may have forensic applications. This model may prove useful for use as a human model and for forensic investigations concerning crimes against animals and the mortality of endangered species.     

关于搞好我省水土保持与走可持续发展道路的思考

我省水资源枯竭与水土流失的现实严重制约着城乡经济的发展。搞好水土保持是我省全面建设小康社会、走可持续发展之路的必然选择。     

居民消费物价上涨对城市低收入人口生活的影响研究

我国居民消费价格从 2 0 0 3年 1月由负转正后 2 1个月上升 ,且主要由于粮食和副食品价格大幅度上涨所致 ,并已对城市低收入人口的生活产生十分不利的影响。本文分析了城市低收入人口的生活状况及物价上涨对其生活带来的不利影响 ,认为必须采取措施 ,对城市低收入人口实施物价补贴 ,以使其基本生活得到保障 ,并提出相应的政策建议     

略论我国土壤污染防治法的基本原则

土壤污染防治法的基本原则是贯穿于土壤污染防治法律之中的根本指导思想或准则,是土壤污染防治法的本质与价值的交接点,对于土壤污染防治法的运作具有现实的意义,它也是克服土壤污染防治法成为成文法局限性的有效工具。土壤污染防治法的基本原则包括预防原则、可持续利用原则、污染者付费原则与综合生态系统管理原则,这四项基本原则是一个有机联系的整体。
