对鉴证准则增加“鉴证对象”的思考  [PDF]
林清林,宋刚
财会月刊 , 2006,
Abstract: 在鉴证实务中,一直存在着在法律上无法对鉴证对象进行明确界定的问题,而套用审计准则来界定在范围上又显得过于狭窄,这一直是影响注册会计师开展鉴证业务的一个重要因素。本文从分析鉴证与审计的区别开始,探讨了鉴证准则增加“鉴证对象”的动因以及影响。【关键词】鉴证准则鉴证对象动因影响将于2007年1月1日起施行的《中国注册会计师鉴证业务基本准则》(简称“鉴证准则”)的第五章增加了“鉴证对象”的相关内容。鉴证准则第五章第二十一条规定,鉴证对象主要分为财务业绩或状况、非财务业绩或状况、物理特征、某种系统和过程、行为五大类,而与这五类鉴证对象相对应的信息形式分别为财务报表、反映效率或效果的关键指标、有关鉴证对象物理特征的说明文件、关于系统和过程有效性的认定、对法律法规遵守情况或执行效果的声明。
试论合同鉴证  [PDF]

法学研究 , 1981,
Abstract: 目前,在国民经济调整和经济体制改革中,各地大都在推行经济合同制度,逐步加强合同管理工作。在合同管理工作中要不要包括合同鉴证这项内容,这是正在讨论的问题。认真研究并解决这个问题,既是实际工作和经济合同立法工作的需要,也具有一定的理论意义。一、合同鉴证的产生和发展合同鉴证在我国产生于五十年代初期。当时,国家采用加工订货、经销代销等形式,对资本主义工商业进行限制、利用和改造。

中国公共卫生 , 1992,
Abstract: ?开原市及毗邻的西丰县位于辽北地区,其东部山区有食用酵米面(臭米面)的习惯。也是酵米面引起食物中毒的高发区。为了探讨本地区酵米面食物中毒发生与气温、气湿等气象因素间的关系,现就本地区1981、1985、19893年间的7起酵米面中毒资料进行分析。

Abstract: ?酵米面食物中毒在我国东北、广西等地时有发生。我国酵米面中毒的病因已经阐明,为一种产生水溶性黄色素的革兰氏阴性无芽胞杆菌。在分类鉴定中有人认为应归于黄杆菌属,也有人认为应定为假单胞菌属。胡文娟等证明此菌之主要毒素为米酵菌酸(bongkrekicacid)。
Solubilization of Hydrophobic Dyes in Surfactant Solutions  [PDF]
Ali Reza Tehrani-Bagha,Krister Holmberg
Materials , 2013, DOI: 10.3390/ma6020580
Abstract: In this paper, the use of surfactants for solubilization of hydrophobic organic dyes (mainly solvent and disperse dyes) has been reviewed. The effect of parameters such as the chemical structures of the surfactant and the dye, addition of salt and of polyelectrolytes, pH, and temperature on dye solubilization has been discussed. Surfactant self-assemble into micelles in aqueous solution and below the concentration where this occurs—the critical micelle concentration (CMC)—there is no solubilization. Above the CMC, the amount of solubilized dye increases linearly with the increase in surfactant concentration. It is demonstrated that different surfactants work best for different dyes. In general, nonionic surfactants have higher solubilization power than anionic and cationic surfactants. It is likely that the reason for the good performance of nonionic surfactants is that they allow dyes to be accommodated not only in the inner, hydrocarbon part of the micelle but also in the headgroup shell. It is demonstrated that the location of a dye in a surfactant micelle can be assessed from the absorption spectrum of the dye-containing micellar solution.

Abstract: ????王鉴为明末清初的四王之一,一生致力于宋元诸家的临仿创承。由于王鉴的家世及他在明末清初的特殊环境中所处的位置,以及其处于董其昌和王原祁、王之间的特殊地位,绘画的价值取向对四王风格的整体构成,占有十分重要的地位。
酵米面黄杆菌食物中毒报告  [PDF]

Abstract: ?酵米面黄杆菌(Flavobacteriumfarinofermentansnov.SP.)是新发现的食物中毒的病源菌。目前,世界各地由该菌引起食物中毒的报告尚罕见。我国东北、广西等地曾有臭米面中毒的报告(臭米面食物中毒的病源菌—1978年黑龙江省卫生防疫站定名为产毒黄杆菌,1979年由酵米面中毒病因研究协作组鉴定,暂定名为酵米面黄杆菌)。

酵纤曲的生产及饲养试验小结
微生物学通报 , 1975,
Abstract: 在伟大领袖毛主席无产阶级革命路线指引下,我国养猪事业有了很大发展。为了提高粗饲料的利用价值,支援养猪业的大发展,我们在公司党委领导下,学习各地制做饲料发酵曲的先进经验,并结合工厂生产的特点,于1973年开始试制酵纤曲。两年来,通过反复试验,巳取得初步成果,粗饲料经酵纤曲发酵后蛋白质、脂肪含量都有所提高,并具酸、甜、软、熟、香等发酵饲料的特点,经过饲养试验,能提高增重率和降低精饲料的消耗。为适应养猪事业发展的需要,我厂已建成年产500吨酵纤曲的生产车间。
Micellar solubilization of ibuprofen: influence of surfactant head groups on the extent of solubilization

Revista Brasileira de Ciências Farmacêuticas , 2005, DOI: 10.1590/S1516-93322005000200012
Abstract: an important property of micelles with particular significance in pharmacy is their ability to increase the solubility of poorly soluble drugs in water, thus increasing their bioavailability. in this work, the solubilization of ibuprofen (ibu) was studied in micellar solutions of three surfactants possessing the same hydrocarbon tail but different hydrophilic head groups, namely sodium dodecyl sulphate (sds), dodecyltrimethylammonium bromide (dtab), and n-dodecyl octa(ethylene oxide) (c12eo8). the results showed that, irrespective of the surfactant type, the solubility of ibu increased linearly with increasing surfactant concentration, as a consequence of the association between the drug and the micelles. the 80 mm dtab and the 80 mm c12eo8 micellar solutions resulted in a 16-fold increase in solubility of ibu when compared to the buffer solution, whereas the 80 mm sds micellar solution resulted in a 5.5-fold increase in ibu solubility. the highest value of molar solubilization capacity (c) was obtained with dtab, c = 0.97, followed by c12eo8 ,c = 0.72, and finally sds, c = 0.23. however, due to the stronger tendency of the nonionic surfactant in forming micelles in solution, at the same surfactant concentration, we obtained the same solubility of ibu in both dtab and c12eo8.
