长释放时间间隔优先调度算法及其可调度性分析

针对混合任务实时调度的需求和现有混合任务实时调度算法的局限性,提出了一种长释放时间间隔优先的混合任务实时调度算法LRIF,该算法采用固定优先级和动态优先级相结合的调度策略,根据非周期性软实时任务作业到达流分布,将一定比例的软实时任务作业当作硬实时作业调度,除了可对周期性硬实时任务提供调度保证外,同时还可确保非周期性软实时任务的可调度率.还提出了LRIF调度算法的可调度性分析方法,并讨论了LRIF调度算法的实现方法.测试结果表明:LRIF调度算法具有更好的调度性能,可有效调度由周期性硬实时任务和非周期性软实时任务构成的混合实时系统.     

Auto-Ignition and Heat Release Correlations for Controlled Auto-Ignition Combustion in Gasoline Engines

Auto-ignition and heat release correlations for controlled auto-ignition(CAI)combustion were derived from extensive in-cylinder pressure data of a four-stroke gasoline engine operating in CAI combustion mode.Abundant experiments were carried out under a wide range of air/fuel ratio,speed and residual gas fraction to ensure that the combustion correlations can be used in the entire CAI engine operation range.Furthermore,a more accurate method to compute the residual gas fraction was proposed by calculating the working fluid temperature at the exhaust valve close timing in the experiments.The heat release correlation was described in two parts,one is for the first slower heat release process at low temperature,and the other is for the second faster heat release process at high temperature.Finally the heat release correlation was evaluated on the single cylinder gasoline engine running with CAI combustion by comparing the experimental data with the 1-D engine simulation results obtained with the aid of the GT-Power simulation program.The results show that the predicted loads and ignition timings match closely with the measurements.     

人间温情的诗意释放——读王跃文的《漫水》

《漫水》通过余公公和慧娘娘从青年到老死的人生中晚期两性相悦、两情相知、两两相护的漫长的情感流程,写出了人类最美好的感情——以爱情为底色、受伦理道德所制约、又超越于伦理道德之上的相生相依、相敬相安的脉脉情深的人间温情。如果说《边城》重在表现人性,那么,王跃文的《漫水》,则重在表现人情,反复肯定了发自心灵深处又慰藉人的心灵的人间温情。通过人间温情的诗意释放,把东方民族淡定恬静的生存形态,把乡村百姓有情有义、有节有度的情感生活方式告白于天下。     

The Deadly Embrace:

The epidemiology of and clinical experience with college students who make suicide attempts converge upon a glaring conclusion: that suicidal students are now paying a high price for experimentation with alcohol and other intoxicating substances. A significant proportion of suicidal students are abusers of psychoactive substances. Their numbers may be small in terms of total college and university populations, but their personal sacrifice and group impact is great. The first section of this chapter reviews the epidemiology of college student suicide and substance use disorder. One objective of the review is to help college clinicians and administrators examine the suicide-substance use relationship from multiple frames of reference. Data from a new survey of the relationship between substance use and suicidality in students are presented. The second section introduces selected issues on the important topic of substance use and suicide prevention. The third section deals with specific clinical aspects of the student with suicidal thinking and the therapy of the post-suicide attempter who uses or has intoxicating substances.     

尿路感染病原菌分布及大肠埃希菌的耐药性分析

目的：了解保山某院尿路感染病原菌的分布情况及大肠埃希菌的耐药情况,为临床合理使用抗生素提供依据。方法：用VITET-2Compact60全自动微生物分析仪鉴定细菌,K—B纸片扩散法做体外药敏试验,统计、分析细菌的检出率和药敏结果。结果：尿路感染病原菌占第一位的是大肠埃希菌（74．2％）,其次为肺炎克雷伯菌（10％）,次之为表皮葡萄球菌（4.3％）;病原菌在临床各科室分布情况为泌尿科45．7％、康复科20％、ICU14.3％;52株大肠埃希菌对13种抗生素的耐药率居前三位的分别为：氨苄西林98％、复方新诺明76．9％、庆大霉素65．4％,52株大肠埃希菌对厄他培南、亚胺培南均敏感;52株大肠埃希菌中产ESBLsIg／29株占55．8％,非产ESBLs的23株占44．2％。结论：医院尿路感染病原菌以大肠埃希菌为主,科室分布以泌尿科为首,尿路感染大肠埃希菌的耐药情况较严重,医院应加强其耐药性监测,医生应依据体外药敏试验结果合理选择抗生素。

Cytotoxicity of Liposomal Paclitaxel in Breast Cancer Cell Line MCF-7

Regarding that the breast cancer is the most prevalent disease among women, paclitaxel, an anti-cancer drug, could be used in treatment of this disease. As paclitaxel has adverse effects, it was used of nanoliposome drug delivery technology in order to reduce adverse effects and improve drug efficacy. Certain ratios of phosphatidylcholine, cholesterol and paclitaxel were synthesized to prepare nanoliposomal paclitaxel. Using Zeta sizer device, the mean diameter of nanoliposomal paclitaxel was obtained 421.4 nm and its encapsulation efficiency was 91.3 %. By dialysis, drug release in nanoliposome paclitaxel formulation within 28 h was studied which was 5.53 %. This study showed that cytotoxicity effect of nanoliposomal paclitaxel is more than that of the standard form.
