讯问全程同步录音录像若干问题探讨

实行讯问职务犯罪嫌疑人全程同步录音录像是由职务犯罪案件的特点决定的。讯问的录音录像在实体意义上是固定口供的手段,在程序意义上属于视听资料证据。讯问录音录像与笔录的同步范围要限定为同案件有关的口供。对录音录像资料的制作必须进行控制,并以相关措施予以保障。     

4株猪瘟流行野毒株病毒结构蛋白E2基因的核苷酸序列分析

应用RT-PCR和nPCR扩增由4株甘肃省近期(1997-1998)猪瘟流行野毒株的E2基因,将其克隆到pGEMTEasy载体上,经转化、筛选、鉴定后,测出核苷核序列.4株流行毒株的E2基因核苷酸序列同源性为89.2%-99.7%,相应的氨基酸序列同源性为93.8%-99.0%.这4株流行毒株;与C-株(疫苗种毒)E2基因的核苷酸序列同源性为82.2%-84.3%,相应的氨基酸序列同源性为87.9%-90.2%,表明近期猪瘟流行毒株与C-株的gp55蛋白之间存在一定的差异.     

现代政府应积极运用三种基本力量－－市场、民主和科学

本文认为现代政府应该积极运用三种基本社会力量,那就是市场、民主和科学.提出要进一步收缩政府活动范围,向政府管理领域引进市场机制,以充分发挥市场的力量;要进一步实施政务公开、纵横分权等措施,以充分发挥民主监督、民主参与和民主自治的活力;要进一步完善科学决策体制,加强政府公务人员和办公设施的科学化建设,以充分发挥科学技术的有效作用.     

双眼视力及其伤残评价作用研究

目的研究双眼视力与两单眼视力的关系,及评价其视力伤残评价作用。方法年龄18~60岁患者1 006名,检测两单眼和双眼最佳镜片矫正视力。结果双眼视力可高于、等于和低于较好单眼矫正视力,三者分别占27.14%、70.78%和1.49%,统计显示两眼视差与双眼相互作用有一定关联(χ~2=54.939,P0.001,r=0.228)。33人单眼视力相同而双眼视力不同。结论双眼视力与两单眼视力、较好单眼视力既关联又有一定不确定性,双眼视力在视力伤残评价中具有特殊作用。     

行政许可法:政府管理体制改革的重大成果

完善社会主义市场经济体制要求进一步改革行政管理体制,推进政府职能转换.我国行政许可法的颁行,改变政府过去无所不包的管理方式,可以从源头上预防和治理腐败,对完善政府监督体制,降低行政成本起着重要作用,是行政管理体制改革的阶段性成果.     

Selective colorimetric determination of TNT partitioned between an alkaline solution and a strongly basic Dowex 1-X8 anion exchanger

The Meisenheimer anions formed from TNT in KOH solutions in alcohol or acetone were used in screening tests for TNT among possible nitro-explosives. The same reaction was used for the spectrophotometric assay of TNT in soil by CRREL (Cold Regions Research & Engineering Laboratory of the U.S. Army) method, also known as Jenkins' method, but the color stability was too dependent on the solution composition and the water tolerance was low, necessitating complete drying of soil samples (which may cause partial analyte decomposition) prior to analysis. This study reports the development of a colorimetric method based on the solid phase extraction (SPE) of the Meisenheimer anion formed from TNT and aqueous NaOH into a strongly basic anion exchange resin Dowex 1-X8 (OH(-) form). The orange-red color that developed both in the solid resin and solution phases was persistent for at least 1h. The resin was let to swell in alcohol, washed first with 1M aqueous NaOH, and then with H(2)O before use. To 5 mL of 4-400 ppm TNT solutions in 1:1 (v/v) acetone-water, 0.5 mL of 5% NaOH was added, diluted to 50 mL with 1:1 acetone-water, and the resulting solutions (containing the orange-red Meisenheimer anion of TNT) were agitated at room temperature with 0.9 g resin for < or =50 min. TNT exhibited a reasonably constant distribution coefficient between the resin and aqueous phases. The absorbance of the filtered solutions was measured against a reagent blank at 500nm. The TNT-loaded resins were regenerated with 1M HCl containing sodium sulfite. The calibration line of filtrate absorbance versus analytical concentration was linear over two orders of magnitude between 0.4 and 40 ppm TNT in final solution. Unlike Jenkins' method, the method was tolerant to 100-fold (by mass) of common soil anions like sulfate, nitrate, and chloride. The basic advantages of the developed colorimetric method over the similar CRREL/Jenkins' method may be summarized as color stability, water and common ion tolerance, lowering of the LOD, and widening of the linear range. As opposed to Jenkins' method, the charge-transfer bands characteristic to colorimetric detection were not obscured by the presence of water. The method is suitable for on-site applications, because the color developed in heterogenous solution was stabilized, and the method can be easily practiced with a portable colorimeter to large numbers of samples.     

禽骨髓细胞瘤病自然病例的病理学研究

对禽骨髓细胞瘤病显性型病鸡、ELISA阳性的隐性型病鸡和阴性对照鸡进行了病理学研究。结果表明 ,临床症状明显的显性型病鸡肝、脾、肾、睾丸 (或卵巢 )、肺等组织有灰白色结节状病灶和不同程度的肿胀 ,甚至在股骨或肋骨等处出现大小不一的硬固肿块 ,镜检病变部位有大量髓细胞样瘤细胞 ,呈典型的骨髓细胞瘤病的病理特征。电镜下瘤细胞病变明显 ,瘤细胞胞膜下疑似病毒样粒子 ;在自然病例肾悬液感染的鸡胚成纤维细胞培养物中巨噬细胞的膜性结构上发现增殖的病毒样凸起。ALV JELISA抗体检测试剂盒检出阳性、无明显临床症状和眼观病变的隐性型病鸡 ,光镜下骨髓、肝、卵巢、心肌等组织中可见与显性型相同的髓细胞样瘤细胞 ,但数量较少。ELISA抗体检测阴性对照鸡骨髓中胞浆含有嗜酸性颗粒的髓细胞明显少于阳性鸡 ,除在肝、卵巢等组织中偶尔出现外 ,其他组织很少见到。     

关于当前兵团反腐败斗争若干问题的思考

近几年来,兵团反腐败斗争在兵团党委的正确领导下,认真贯彻"三个代表"重要思想,始终坚持中央关于反腐败斗争的指导思想和工作方针,紧紧围绕兵团党委的中心工作,始终坚持服从服务于兵团改革、发展、稳定的大局,在多方面发挥了重要的作用.但是,也要看到,在新阶段,兵团的腐败现象呈现出一些新特点,给反腐败工作带来一定难度.根据党的十六大提出的要毫不动摇地把反腐败斗争深入进行下去的要求,我们必须加大反腐败工作的力度,不断取得反腐败斗争的新胜利.
