群众路线是我们党的根本工作路线。在社会转型和执政方式转变过程中面临的新形势和新挑战下,如何坚持党的群众路线,成为一项重要课题。永善社区通过依靠群众、组织群众、发动群众,成立党委领导下的市民劝导队,在实践中坚持和发扬群众路线,实现了社区善治和美丽社区梦。     

论毛泽东军事思想的基本点

在毛泽东军事思想的科学体系中 ,实事求是是精髓 ,群众路线是核心 ,独立自主是基础 ,这三者是相互联系、相互贯通、辩证统一的有机整体 ,是毛泽东军事思想的基本点 ,自始至终地贯穿于毛泽东军事思想的各个方面。     

毛泽东思想对新形势下公安群众工作的指导意义

群众工作是公安工作的一项重要课题,也是基层公安派出所基础工作的一项重要课题。现阶段公安群众工作中还存在诸多与群众路线不相适应的问题。毛泽东同志对群众路线的论述,对解决基层公安群众工作存在的问题、加强当前公安基础工作具有重要的指导意义。

用串联质谱法提高毒鼠强的检测灵敏度

目的建立一种能避免生物样品中杂质的干扰,提高毒鼠强检测灵敏度的方法。方法应用串联质谱法,对生物样品中的毒鼠强进行检验研究。结果在样品无需净化的情况下,以m/z240为母离子,当激活电压在0.8V左右时,毒鼠强二次电离的离子碎片适中,质谱谱图清晰;此时进样量为1.0ng的毒鼠强,其信噪比(s/n)为87,经与全扫描质谱法进行比较灵敏度大为提高。结论该方法能有效提高毒鼠强检测灵敏度,适用于同类案件检验。     

大众传媒:军营文化建设的重要力量

作为传播信息的工具和传播文化的载体，大众传媒在加强军营文化建设方面具有突出的特点和独到的优势：营造浓厚的“文化场”，让官兵在潜移默化中提高政治思想水准和科学文化素质；发挥导向作用，帮助官兵在复杂多元的文化现象中作出正确的判断和选择；对军队文化建设工作实施有力有效的指导作用。真正做到如此，关键取决于领导的认识到位和媒介工作者文化自觉的增强。     

商业银行资产负债期限结构错配的流动性风险和利率风险分析

本文结合目前我国商业银行普遍存在的资产负债期限结构错配的现状,分析了产生流动性风险和利率风险的可能性,并认为利率风险是因流动性风险而派生出的风险。在此基础上,提出了商业银行流动性管理的三种方法:期限匹配法、资产组合法和综合法。     

从“以人为本”的视角看大众文化的先进性

对大众文化的评价是一个颇多争议的问题。合理评价大众文化首先必须摈弃精英主义的视角,真正确立"以人为本"的正确视角。从这一视角出发,大众文化的先进性体现在:其一,大众文化提升了普通大众的文化主体地位;其二,大众文化蕴含着对人的感性欲求的尊重。现实中的大众文化虽有种种不足,但其内在的先进性决定了我们应该以建设性的态度去面对它。     

生物组织中甲胺磷及其异构体的串联质谱法分析

目的建立可用于生物体内甲胺磷及其异构体O,O二甲基氨基硫代磷酸酯检验的高灵敏度方法。方法应用串联质谱法(GCMS/MS),对生物样品中的甲胺磷及其异构体进行检验研究。结果选择质荷比为141的离子为母离子,击发电压为0.8V时,甲胺磷及其异构体二次电离碎片适中,质谱谱图清晰。50%甲胺磷乳油进样量为0.1ng时,甲胺磷及O,O二甲基氨基硫代磷酸酯峰的信噪比分别为436、773。经实验,甲胺磷检测限为20pg。结论所拟方法能有效提高甲胺磷的检测灵敏度。     

Influence of storage on larval length and age determination of the forensically important blow fly Lucilia sericata (Diptera: Calliphoridae)

One of the main tasks in forensic entomology is the determination of the minimum post-mortem interval (PMI_min) based on the age of the juvenile insects feeding and developing on the dead body. An important task is to store the evidence appropriately so that the evaluation and expert report can be used in court. However, existing recommendations can be contradictory or lacking scientific validation, e.g. by proposing various preservation liquids without knowing whether and to what extent the period of storage in such a liquid has an effect on the length of the preserved larvae. Storage time can be an issue since, due to technical and procedural circumstances, killed larvae may be stored for hours, days, weeks or even longer prior length measurement. A changed body length would have consequences for the entomological report, as the age of the larvae is usually derived from their length.This study investigates the effect of four differently concentrated ethanol solutions (70%, 80%, 90% and 96%) during a storage period of up to 196 days on the body length of stored larvae of the forensically important blow fly species L. sericata (Diptera: Calliphoridae). Larvae of different ages (24 h, 48 h and 72 h after hatching) were killed by immersion in hot, non-boiling water (≥80 °C) for at least 30 s. Their lengths were measured immediately. Subsequently samples were stored in ethanol of appropriate concentration at room temperature (approx. 22 °C). Further length measurements were made at 16 different storage intervals between 1 and 196 days.Many specimens showed a length decrease for most storage conditions and all larval ages. However, there was a tendency for 48 h- and 72 h-old larvae to increase in length after the first days of storage of up to 1.1 mm which may lead to an erroneous overestimation of the PMI_min using this kind of specimens. All changes in length within each cohort over total time were in the range of +7% to −9.1%. Significant differences in length changes within the first days of storage were found mainly in larvae stored in 70%- and 80%-ethanol, but larvae stored in 90%- and 96%-ethanol showed first significant differences on day 56 at the earliest.Our results lead to the recommendation that the measurements of fly larvae samples should be taken immediately after killing and before storage to avoid any effects. Ethanol ≥90% should be used for storage.
