The Portland cement concrete pavement(PCCP)often suffers from different environmental distresses and vehicle load failure,resulting in slab corner fractures,potholes,and other *** repair has become one of the effective ways to open traffic *** this study,a novel type of rapid repair material,basalt fiber reinforced polymer modified magnesium phosphate cement(BFPMPC),is used to rapidly repair ***,the mechanical properties and characteristics of the repair interfaces which are named interfacial transition zones(ITZs)formed by BFPMPC and cement concrete are focused on as a decisive factor for the performance of the rapid *** changing trend of the elastic moduli was studied by nanoindentation experiments in the ITZs with the deconvolution analysis that the elastic moduli of certain kinds of substances can be *** experimental results show that the elastic modulus of ITZ-1 with a width of about20μm can be regarded as 0.098 times of the aggregate,and 0.51 times of the ordinary Portland cement(OPC)*** BFPMPC-OPC mortar ITZ has roughly the same mechanical properties as the ITZ between aggregate and BFPMPC.A multi-scale representative two-dimensional model was established by random aggregate and a two-dimensional extended finite element method(XFEM)to study the mechanical properties of the repair *** simulation results show that the ITZ formed by the interface of BFPMPC and OPC mortar and basalt aggregate is the most vulnerable to failure,which is consistent with the nano-indentation experimental results.

作者： Ruixue Yin Bingxun Lu Lixin Wang Jianzhong Fan changjun Lu Hongzhen zhou Department of Neurology Nanfang Hospital of Southem Medical University Guangzhou 510515 Guangdong Province China

BACKGROUND ： Basic fibroblast growth factor （bFGF） can cause proliferation and differentiation of plentiful cells which are derived from mesoblast and neural ectoblast. Previous researches suggested that Tongxinluo could promote differentiation from neural stem cells （NSCs） to neurons and astrocytes after cerebral ischemia/reperfusion injury.OBJECTIVE： To observe the effect of Tongxinluo on bFGF mRNA of rats after cerebral ischemia/reperfusion injury and analyze its dosage-dependence. DESIGN ： Randomized controlled study SETTING ： Department of Neurology, Nanfang Hospital of Southem Medical University MATERIALS： The experiment was carried out in Neurological Department of Nanfang Hospital affiliated to Southern Medical University from May 2005 to March 2006. A total of 192 healthy Wistar rats, weighing （200±20） g, of SPF grade, of both gender by half, were provided by Experimental Animal Center of Nanfang Hospital Affiliated to Southern Medical University. Tongxinluo was consisted of renshen, wugong, quanxie, shuizhi, chishao, bingpian, etc. and was provided by Shijiazhuang Yiling Pharmaceutical Co., Ltd. （batch number： 9906115）. Main reagents： Agarose, DEPC-treated water, total RNA purification kit and one-step reverse transcription polymerase chain reaction （RT-PCR） kit were provided by Beijing Saibaisheng Gene Technique Co., Ltd. METHODS ： All rats were randomly divided into 4 groups, including high-dosage Tongxinluo group, low-dosage Tongxinluo group, model group and sham operation group with 48 in each group. Rats in the former three groups were observed at 3, 5, 7, 14, 21 and 30 days after ischemia/reperfusion. In addition, rats in sham operation group were selected at the relevant time points. Every 8 rats were selected from each group for once. （1） Right middle cerebral artery occlusion-reperfusion models were induced by Koizumi method and modified; moreover, neurological impairment was evaluated with Zealonga method. Except rats in sham operation

相对于认罪认罚从宽制度在刑事诉讼中适用的火热场景,以审判为中心的诉讼制度改革推进状况颇不令人乐观,呈现出文本“热”与实践“冷”的反差。实体真实优先性的刑事诉讼观念、非正式性的纠纷解决传统、可控性的程序运作思维、行政性的审判管理方式是以审判为中心的诉讼制度改革遭遇困境的症结所在,法官对庭审实质化的心理排斥则是改革最直接的障碍。期望在维持案卷移送制度的前提下,通过审判机制、程序技术或证据制度的调整走出改革困境,实践证明很难成功。推进以审判为中心的诉讼制度改革,应当进行宏观的制度性变革,构建中国式诉因制度,改革人民陪审员制度,阻断侦诉卷宗信息对裁判结论的实质性影响,激发法官的内生动力,同时完善司法管理方式和问责机制,破解制约审判权独立行使的体制机制障碍,营造良好的司法环境。

在现代刑事诉讼中,缺席审判程序的正当性建立在被告人事先知悉开庭信息和听审权并自愿放弃此权利的基础上。从适用条件看,'犯罪嫌疑人、被告人在境外'不仅指有可信的证据证明犯罪嫌疑人、被告人已经出境,而且指犯罪嫌疑人、被告人未死亡。缺席审判启动的证据条件是'有明确的指控犯罪事实'。外逃人员缺席审判开庭信息的送达应当以送达被告人本人为原则,送达与被告人共同居住的成年家属或者被告人指定的代收人为例外;直接送达有困难时,在被告人所在国的法律允许情况下,可以采取邮寄送达的方式;经被告人同意,可以采用传真、电子邮件等送达方式;原则上不能单独使用公告送达方式。缺席审判程序与违法所得没收程序无法相互替代;缺席审判的提起并非当然地涵盖违法所得没收申请的提出,法院作出无罪判决时不可附带作出违法所得的没收,缺席审判程序停顿状态下也不可独自开展违法所得没收程序;在被告人死亡的情形下追缴违法所得,只能启动违法所得没收程序。对于司法机关违反法定适用条件启动缺席审判的行为,应当确立一定的制裁性法律后果。

监察委员会调查职务犯罪的程序构造对于监察权力的行使、职务犯罪的控制和被调查人合法权益的保障具有重要的"框架性"制约意义。试点期间监察委员会对职务犯罪调查的程序构造采行"线性结构"模式,具有鲜明的行政化和封闭化色彩,尽管有利于提升打击腐败犯罪的成效,但也存在不容回避的风险。吸取我国过去刑事侦查程序建设的经验和教训,并参考《联合国反腐败公约》和其他法治国家的相关规定,应当建构"三角结构"的监察委员会调查犯罪程序,在监察机关与被调查人的"对垒"程序中,检察机关作为客观、中立的"第三方"介入进来,制衡监察权力的行使,保障被调查人的合法权利。作为配套措施,应当构建独立的职务犯罪立案程序。

影响坦克炮射击精度的主要因素之一是火炮振动 ,起关键作用的振动分量是在弹丸出炮口瞬间炮口振动角位移和横向线速度。为提高坦克炮射击精度 ,本文推崇“对称布置”和“初期自由后坐”的总体设计思想 ,使火炮射击时炮身和摇架所受的力矩尽量减小 ,同时使炮塔和车体在弹丸出炮口前的受力也尽量减小 ,从而减小了炮身的振动 ,也减小了炮塔和车体的振动 ,这对提高坦克炮射击精度将是十分有利的。本文运用动力学分析计算方法 ,阐明有关总体结构参数对坦克炮射击精度的影响。

目前我国相关规范性文件所确立的平面式受审能力认定标准,虽有助于提升诉讼效率、维护程序德性和保障案件真实发现,但也存在未能有效保障被告人自主权、公共利益维护难以及鉴定专家主导受审能力的认定等问题。为此,应改采进阶式认定标准,将受审能力区分为参加庭审的基础能力与放弃自主行使的诉讼权利的决定能力。进阶式受审能力认定标准能够较好地平衡被告人自主权的防御功能与处分功能,促进公共利益与被告人个人权益的协调实现。重疾类被告人可否缺席审判不宜一概而论。
