隧道含水围岩非均质各向异性渗透特性的硏究  [PDF]
杨立中,黄涛,钟生军
铁道工程学报 , 1996,
Abstract: ?在隧道突水预测中,由于含水围岩渗透具有较强的非均质各向异性,常影响隧道突水预测、预报的准确性。为了解决这个问题,本文以中国南昆铁路二排坡隧道为例,提出了用渗透张量新方法进行隧道含水围岩非均质各向异性渗透的计算分析,以提高隧道突水来源、突水位置、以及突水量的预测预报准确度。
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。

BACILLUS CEREUS: ISOLATION IN JENNET MILK
M.L. Scatassa,A. Carrozzo,B. Ducato,C. Giosuè
Italian Journal of Food Safety , 2011, DOI: 10.4081/ijfs.2011.1s.243
Abstract: Jennet milk as human food is hypoallergenic for patients affected by Cow Milk Protein Allergy and multiple food allergies. For these pathologies, jennet milk represents the best alternative to other types of milk. Therefore, jennet milk consumers are very sensible to the effects of pathogens' contaminations, and several hygienic practices during the milk production need to be adopted. During regular monitoring in one Sicilian jennet farm, Bacillus cereus in the milk was detected. In 3 bulk milk samples (maximum concentration: 1.2 x 103 ufc/ml), in 3 individual milk samples (10, 20 e 60 ufc/ml), in the milk filter (5 ufc/cm2), in the soil (maximum concentration: 1.5 x 103 ufc/g), on the hands and the gloves of two milkers, on the animal hide (from 1 to 3 ufc/cm2). No spores were detected. A total of 8 Bacillus cereus s.s. strains were analyzed for diarrhoic toxin, and 6 strains producing enterotoxins resulted. The improvement of environmental and milking hygienic conditions reduced Bacillus cereus concentration.
Production, Secretion and Biological Activity of Bacillus cereus Enterotoxins  [PDF]
Sonia Senesi,Emilia Ghelardi
Toxins , 2010, DOI: 10.3390/toxins2071690
Abstract: Bacillus cereus behaves as an opportunistic pathogen frequently causing gastrointestinal diseases, and it is increasingly recognized to be responsible for severe local or systemic infections. Pathogenicity of B. cereus mainly relies on the secretion of a wide array of toxins and enzymes and also on the ability to undergo swarming differentiation in response to surface-sensing. In this report, the pathogenicity exerted by B. cereus toxins is described with particular attention to the regulatory mechanisms of production and secretion of HBL, Nhe and CytK enterotoxins.
