    烟草行业在我国是一个特殊的行业,烟草的销售实行专卖制度,烟草销售的渠道是从卷烟企业——烟草公司——销售商——消费者。由于烟草的生产和销售受国家调控和政策法规影响很大,长期以来,烟草销售在行业中并不受重视,烟草销售的理念比较陈旧。但随着市场的逐渐开放,烟草行业的内部竞争、国际竞争越来越激烈,烟草企业需要引入更科学、更先进的管理理念和工具。本研究就是要为烟草企业编制一个精简节约的高效率销售管理系统,帮助企业大幅度提高销售管理的效率。 本文从烟草行业的销售发展过程、营销渠道以及具体销售流程的特点入手,探讨了我国烟草行业营销未来的发展方向。并以此为依据分析了销售管理系统的需求。 系统开发选用了C#...The tobacco industry is a special industry in our country, and the sale of tobacco products is the implementation of monopoly institution.

    分区边界的确定是生态分区的重要步骤,但目前多数水生态分区的边界确定以定性分析、专家判断为主。本研究以洱海流域为例,建立了一套两级分区体系。该体系基于GIS技术,用子流域作为分区基本单元,并用相关分析法,定量筛选一、二级分区指标。其中,一级分区指标为高程、坡度和植被归一化指数(NDVI),二级分区指标为农田百分比和城镇百分比。通过指标图层的叠加和重分类,合并同质性子流域,从而将洱海流域划分为5个一级区和9个二级区。藻类群落分布的验证结果表明分区合理。本研究将定量分析和子流域边界应用于水生态分区,使分区边界的确定更科学,在实际管理中更具有可操作性。本研究结果为水生态分区研究提供了新的方法,为洱海流域水生态管理提供了基本管理单元

    Role of alternative polyadenylation in epigenetic silencing and antisilencing

    Get PDF
    Epigenetic marks such as DNA methylation and histone modifications are widely involved in regulating different aspects of developmental and environmental responses (1). Meanwhile, DNA methylation and histone modification are also used constitutively to silence transposable elements and repeat elements (TREs) (2). Such TRE-mediated silencing should necessarily be limited to the intended targets only and not spread to adjacent genes and their regulatory elements. Higher eukaryotic organisms have evolved antisilencing mechanisms to keep the balance between silencing and antisilencing that is required for precise gene expression regulation.Research in the authors' laboratory is supported by US National Science Foundation Grant IOS–0817829 (to Q.Q.L.) and US National Institutes of Health Grant 1R15GM94732-1 A1 (to Q.Q.L.)
