摘要：建筑工程质量安全监督管理是一项系统性工作,是全面保障建筑工程各个环节质量安全的重要环节,是切实维护人民群众生命财产安全和社会和谐稳定的重要基础。分析高校建筑工程质量安全监管存在的诸多问题,提出相应的解决对策:完善法律法规体系,强化制度保障;优化安全监管体系,提升监管实效;坚持技术创新,提升监管水平;完善培训机制,提升人员素质。

摘要：在语文教学中,教师应尽可能多给学生提供表现的机会,充分拓展其学习空间,以锻炼他们各方面的能力。一、把课文中的内容画出来小学语文课本中有许多内容片段如同一幅幅多彩的画面,在课堂教学中,老师调动学生的眼、耳、口、手等多种感官,让这些画面浮现在学生头脑中并令其用语言描述出来。如学习《赵州桥》,就让学生用积木做模型,体会赵州桥设计上的创举。学习古诗,让学生在理解内容的基础上,把“话”变成“画”,再将“图”与诗结合起来欣赏、讲解,把“画”还原成“话”。学完《我要的是葫芦》后,让学生想象:假如课文有5幅插图的话,第五幅图应该画什么、写什么?学生兴趣盎然地动脑筋想、动手画、动笔写,从而加深对课文的理解。二、把课文中的内容演出来采用娱乐活动(如演课本剧、举办故事会、配乐朗诵会等),引导学生学语文,如学习《伏尔加河上的纤夫》,我们就让学生学当讲解员,为同学们讲解这幅油画。任务一布置,每个学生都开始仔细读课文,思考怎么来讲解,学生都学得格外认真。三、创没口语交际情境,引导学生模拟实践对于小学生来说,采用直观形象的教学手段,教学效果是不言而喻的。如在课堂上进行说话训练时,充分发挥多媒体的作用,创设情境,把教室变为商店、医院等,用录...

摘要：Rapid and sensitive detection of various analytes is in high *** from its application in genome editing,CRISPR-Cas also shows promises in nucleic acid detection *** further exploit the potential of CRISPR-Cas for detection of diverse analytes,we present a versatile biosensing platform that couples the excellent affinity of aptamers for broad-range analytes with the collateral single-strand DNA cleavage activity of CRISPR-Cas12 *** demonstrated that the biosensors developed by this platform can be used to detect protein and small molecule in human serum with a complicated background,i.e.,the tumor marker alpha fetoprotein and cocaine with the detection limits of 0.07 fmol/L and 0.34 lmol/L,respectively,highlighting the advantages of simplicity,sensitivity,short detection time,and low cost compared with the state-of-the-art biosensing ***,this biosensing platform with plug-and-play design show great potential in the detection of diverse analytes.
