背景:世界范围内的卫生系统都面临资源限制。因此,通过科学循证决策来削减成本并防止资源浪费非常重要和必要,本研究旨在分析伊朗卫生系统循证决策的障碍。方法:通过对决策者的深度访谈和焦点小组讨论收集数据,共进行了13次访谈和6组焦点小组讨论,并对数据进行了主题分析。结果:障碍涉及决策者特点、决策环境和研究系统三个方面,每个方面由相关主题和分主题构成;机构价值观、选择决策者的标准、对循证决策的态度是循证决策的重要障碍,并且与管理有关。结论:循证决策有不同层级的障碍,需要从多个角度寻找强化科学循证决策影响的解决方案;几个已经确定循证决策的障碍植根于卫生体系治理,如跨部门合作的薄弱、没有制定卫生研究重点。因此,为做好循证决策,加强卫生系统管理势在必行。

评价3种不同化合物(腐植酸、酵母提取物和过氧化氢)和2种培养基(矿物盐溶液和原核培养基)在有氧条件下,对提高苯的生物降解起到的作用。结果表明,酵母提取物比腐植酸可以更有效地提高苯的生物降解。同时添加酵母提取物和腐植酸可以提高苯的去除率,去除率的多少取决于酵母提取物的浓度。在过氧化氢中,苯的去除率增加了55%以上。在原核培养基中苯的去除率高于在矿物盐培养基中的苯去除率。
