关键词： 弥漫性血管内凝血   凝血   诊断   指标  

摘要： 目的:探讨凝血检验指标在弥漫性血管内凝血诊断中的意义。方法:选取我院2014年3月至2015年3月的40份凝血检验结果进行回顾分析比较,按照健康状况不同,分为健康组(n=20)和DIC组(20),通过对比分析两组成员的内源性凝血状态(APTT)、外源性凝血状态(PT)、纤维蛋白原含量(FIB)以及纤维蛋白原转化为纤维蛋白的时间(TT)进行凝血检测。结果:健康组成员凝血时间短,纤维蛋白原含量高,而DIC组凝血时间较健康组成员长,且纤维蛋白含量低,纤维蛋白原转化为纤维蛋白的时间也相对较长(p<0.05)。当患者需要手术时,应首先了解患者止血功能是否存在缺陷,防止术中大出血而导致死亡。结论:通过检验患者凝血指标,能够在手术前判断患者止血功能,做好应对准备,防止术中发生手术意外,提高手术成功率。

关键词： 父母教养方式   身体质量指数   饮食摄入量   身体活动量   调节作用  

摘要： 超重与肥胖已成为困扰人类健康的世界性难题,现已被世界卫生组织列为导致疾病的十大危险因素之一。造成超重与肥胖的主要原因是个人饮食能量摄入和身体活动消耗的不平衡。而有研究表明父母的教养方式(专制型、权威型和放任型)以及在饮食和身体活动这两方面的行为会对子女这两类健康行为的发展造成影响。研究方法:本研究包括两部分,研究一针对父母权威问卷(Parental Authority Questionnaire)进行修订及信效度检验。研究二运用横断式研究设计。采用父母权威问卷(Parental Authority Questionnaire),食物频率问卷(Food Frequency Questionnaire)和国际体力活动问卷(Global Physical Activity Questionnaire),对176名大学生及其父母其中一方进行问卷调查,。运用Pearson相关和多元线性回归分析考查父母教养方式对子女体重相关的健康行为的影响作用。研究结果:(1)修订后的父母权威问卷具有一定的信效度,可以作为测量中国父母教养方式的工具。(2)大学生及父母在身体质量指数(BMI)和每日平均饮食摄入量上均具有显著性相关(BMI:r=.19,p<.05;饮食摄入量:r=.53,p<.001),而在每周平均身体活动量上不具有显著相关(r=.08,p=.17)。(3)专制型父母教养方式对父母与子女BMI的相关关系起调节作用(p<.01),即高专制得分组和平均值专制得分组的父母与子女BMI呈正相关关系,而低专制得分组的父母与子女的BMI呈负相关关系。(4)放任型父母教养方式对父母与子女日均饮食摄入的相关关系起调节作用(p<.05),低放任得分组在父母子女间饮食摄入的正相关关系强于高放任得分组。研究结论:本研究验证了在大学生子女离开家庭环境后,父母和子女在BMI以及饮食摄入量方面仍存在相关关系,父母的教养方式也会持续对子女BMI及饮食行为产生影响。这为今后在青少年肥胖干预研究中纳入家长教养因素提供了实证依据,并为从家庭方面控制子女肥胖及帮助子女塑造健康行为提供了可行性建议。

摘要： The rise of atypical workers, such as fixed-term or part-time workers, has become a hot issued in employment law and employment market policies across the world. The judgment of the Spanish Constitutional Court, dated 16 July, 2014, analyses three provisions of Law 3/2012 on labour reform and their compliance with the Spanish Constitution. Specifically, the Parliament of Navarra"s appeal challenges, among other aspects, the one- year trial period in permanent employment contracts to support entrepreneurs. The Spanish Constitutional Court dismisses the appeal. Regarding the one-year trial period, the Constitutional Court holds that, the aim to create employment under the provision is legitimate. Moreover, after weighing up the constitutional rights at stake, the Constitutional Court concludes that, the one-year trial period is reasonable, particularly in view of the economic situation in Spain and given that this provision will only be effective if the unemployment rate exceeds 15 per 100. Asked by a Spanish court whether this provision is compatible with EU law, the European Court of Justice found itself without jurisdiction to answer the question. This paper will try to explain the one-year trial period in permanent employment contracts, the judgments of the Spanish Constitutional Court and the European Court of Justice.

关键词： lithium ion battery   cell classification   battery pack   self-organising map   electric vehicles  

摘要： This paper presents a self-organising map (SOM) based classification of lithium iron phosphate cells for a battery pack in EVs. The experimental data of the cells have been obtained to train the SOM. The temperature variation, internal resistance and available capacity of the cells are used as the inputs of the SOM, and the output of the SOM classifies the cells into three groups with the similar characteristics in terms of its input parameters. Then, the cells in the same group are connected in series to build a sorted battery pack whereas the randomly chosen cells are connected in series to build an unsorted battery pack. The comparison of the consistency between these two battery packs under different discharging conditions has demonstrated the effectiveness of the proposed classification method. In addition, the experimental results show that state of charge based approaches for cell balancing are more effective than voltage based approaches.

关键词： Antioxidant   Aqueous   Leaves   Methanol   Olive   Taxonomy   Total phenolic  

摘要： Interest of using naturally occurring antioxidants had been increased in our life to replace undesirable harmful synthetic antioxidants. In the present study, the antioxidant activity and total phenolic content of methanol and aqueous extracts of wild African (Olea europaea subsp. cuspidata (Wallich ex G. Don) Ciferri) and cultivated Mediterranean (Olea europaea subsp. europaea L.) olive leaf samples growing in Taif, KSA were estimated. All methanol and aqueous extracts showed high DPPH free radical scavenging activity with SC50 < 40 μg/ml. The extracts of wild olive have higher antioxidant activity than the cultivated olive. The methanol extract in the same subspecies showed higher antioxidant activity and total phenolic content than the aqueous extract. Positive correlation appeared between the antioxidant properties and phenolic content. In conclusion, these two subspecies may have great relevance in the prevention and therapies for diseases in which free radicals or oxidants are implicated after more phytochemical and biological studies. Phytochemical analysis confirmed the present taxonomy of African and Mediterranean olives as subspecies of Olea europaea L. At present, the authors started with a detailed phytochemical analysis of these extracts by LC-MS.

摘要： This dissertation lays the foundation for linguistic inquiry into the question of how speakers of English know when a contractual offer has been made. Of primary interest here is the issue of whether the perception that an offer has been made is somehow, apparently silently, reflected in the syntax and semantics of the language of the offer itself or whether such a perception is a matter of intention on the part of the speaker and/or inference on the part of the hearer – notions that have no real reflection in the “literal” meaning of the language of offers in the typical case. Using traditional linguistic methodology, I argue that the latter is more likely: In particular, I show that the postulation of silent offer or promise elements in the syntax and semantics of a typical contractual offer produces incorrect predictions as to which sentences of English should be viable contractual offers and as to what contractual offers should mean. The dissertation is written for popular consumption, so no expertise in linguistics (or law) is presumed.

关键词： 航空产品   质量控制   质量检验   作用  

摘要： 航天商品科技含量极高,结构设计精密复杂,每一个合格的航空产品都是由质量合格的整体框架、子系统、电子部件、元器件及软、硬件系统组成的,具有高科技设计与组装复杂的特殊性。这使得航空产品及其零部件的衍生品在生产过程中,质量检验工作难度系数较大。但是航空产品在使用过程中,只要出现微小的的疏忽就有可能酿造严重航空事故,所以质量检验工作必不可少。本文重点研究了航空产品质量控制过程中质量检验的作用,希望对提高我国航空技术水平有所帮助。
