A method has been developed on reverse phase high performance liquid chromatography for simultaneous determination of methyl, ethyl and isopropyl alcohols under refractive index detection using pure water as the mobile phase. A good separation has been achieved between these alcohols. Detector response was linear with a detection limit of 5 mg/100 ml. Recovery studies were performed by adding known amounts of methyl and ethyl alcohols to blood, lung and liver within the range 80–90%. The reproducibility of the results was always >90%. The quantitative distribution of methyl alcohol in postmortem body tissues and fluids has been reported in three cases of poisoning. 相似文献

<正> 按照规定,大学本科学生和研究生,包括博士研究生,毕业前都必须写作毕业论文.毕业论文究竟应当怎么写呢?常有同学向我提出这个问题.这使我想起了鲁迅先生写的一篇题为《作文秘诀》的文章.但这篇文章并不是真正告诉人们以什么作文的"秘诀",而恰恰是指出作文并没有什么"秘诀";所谓"秘诀",无非是写作时装腔作势,故弄玄虚,用某种障眼法吓唬人、愚弄人罢了.那么,作文就没有什么要注意的么?当然也有.用鲁迅的话说,那就是"有真意,去粉饰,少做作,勿卖弄".我想这道理同样适用于写作毕业论文. 相似文献

A comparison of three groups of Title IV-E child welfare workers revealed significant differences among all groups on job expectations and career goals. New workers reported most positive expectations for their jobs, and greatest interest in child welfare careers and in pursuing educational goals. Seasoned workers expressed least positive expectations and least interest in future child welfare careers and educational goals. Findings may assist universities in student selection and curriculum. Child welfare agencies may benefit in areas of recruitment, training, and policies. Realistic job previews might moderate high expectations for new workers and reduce unmet expectations for experienced workers. 相似文献

国家权利是国家就维持其存在和履行职能所应有利益而享有的一种支配自由。国家也会受到犯罪的侵害 ,国家被害的客体是国家权利。国家权利也有防御犯罪和利益补救的护卫需求。 相似文献

The eyes of fourteen fatally abused children and sixteen control cases were examined histopathologically. Ten of the abused children showed intraocular change. The most common ocular changes were subdural hemorrhage of the optic nerve and retinal hemorrhage which involved all the layers of the retina, but most commonly the nerve fiber layer, ganglion cell layer and inner nuclear layer. The presence of blood cavities within the retina partially supported the hypothesis of traumatic retinoschisis. The control cases of non-abused children rarely showed intraocular hemorrhage. 相似文献

目的 根据ERP理论和韦氏智力量表内容建立数字计算ERP范式,探讨正常人与重型颅脑损伤患者数字计算ERP特征及与智商的相关性.方法 采用Neuroscan-ERP仪和韦氏智力量表对29名重型颅脑损伤患者(外伤组)和46名正常人(对照组)进行ERP及智商检测,比较引出的ERP成分特征及与智商的相关性.结果 数字计算范式的题目、正确、错误答案3类刺激引出的ERP波形包括外源性成分N1c、P2c及内源性成分N2c和P3c;对照组引出的N1c和P2c波幅和潜伏期相近,但N2c和P3c有明显差异,其中正确答案的P3c波幅最高,错误答案的P3c潜伏期最长;外伤组引出的各ERP成分波幅降低、潜伏期延长,N2c和P3c具有显著性差异(P<0.05);对照组错误答案引出的P3c潜伏期与言语智商和总智商呈中度负相关,高于题目和正确答案;外伤组P3c潜伏期与言语智商、操作智商和总智商的相关系数分别为-0.64、-0.46和-0.60(P <0.05),明显高于对照组.结论 数字计算ERP范式可引出特征性ERP波形,其P3c潜伏期与智商有一定相关性,可作为评价重型颅脑损伤后数学能力损害程度的参考指标. 相似文献

Narasimha D. Rao 《International Environmental Agreements: Politics, Law and Economics》2014,14(2):129-146
Is inequality within countries relevant for global climate policy? Most burden-sharing proposals for climate mitigation treat states as homogenous agents, even those that aim to protect individual rights. This can lead to free riders in some large emerging economies and expose the poor to mitigation burdens in others. Proposals that incorporate an exemption for the poor can avoid these outcomes, but do not account for the role of internal policies on the poor’s actual emissions and mitigation burdens. This will create moral hazards in the design of such agreements and risk the misallocation of mitigation costs when implemented. To ensure equitable outcomes at the individual level, international agreements would need to build in additional provisions to encourage benefiting states to reduce emissions and target exemptions to the poor. But such agreements will face political conflicts over sovereignty and the burdensomeness of such provisions. 相似文献
