冀西北马铃薯田间杂草化学防治研究

[目的]寻找控制冀西北地区马铃薯田间杂草的有效化学防除方法.[方法]在经48%氟乐灵乳油和50%乙草胺乳油处理过的马铃薯田间使用15%精稳杀得乳油和24%果尔乳油进行除草试验.[结果]研究结果表明,50%乙草胺乳油在播前进行土壤处理比48%氟乐灵乳油具有不影响出苗率的优点,效果更好;播种前用50%乙草胺乳油2 625 mL/hm2处理过的土壤,苗期用24%果尔乳油300、450ml/hm2可以很好地防治田间杂草.在冀西北地区马铃薯生产中使用化学除草可以节省成本1 050～1 080元/hm2.[结论]播种前药剂处理土壤结合苗期化学防治是控制冀西北地区马铃薯田间杂草的有效途径.

2010年7月19日河南省安阳区域性暴雨过程分析

利用天气图资料、物理量场、卫星云图、雷达回波等气象资料,对2010年7月19日河南省安阳区域一次典型暴雨天气过程进行分析,进而对该市区域性暴雨天气过程的特征进行总结.结果表明,造成此次区域性暴雨的主要影响系统是西太平洋副热带高压及其西北侧的西风带低槽和西南低涡,属于典型的北槽南涡型暴雨天气类型.低槽引导西南低涡东北上,槽后明显的冷空气与西南低涡东北上、副高外围边缘的西南暖湿气流交汇,共同影响造成了安阳这次区域性暴雨过程.较强降水并不是产生在亮温(T<,bb>)低值中心处,而是产生在其附近的等值线密集带内,这是由于T<,bb>最低时,云顶最高,此时往往是云体发展最旺盛的阶段,并不是降水最强的时候,只有在云顶逐渐下降时,降水才能达到最强.从雷达回波上看,降水回波大体上是从西南往东北移动的,回波强度最大为48 dBz.     

2010年6月初广西一次极端暴雨特征分析

利用NCEP1°×1°再分析资料、常规观测资料、自动雨量站加密资料及卫星资料,对2010年6月初广西来宾、都安极端暴雨过程的环流背景和中尺度系统进行了分析.结果表明,此次暴雨过程前无急流建立,850 hPa 2支气流在暴雨前明显加强.过程中副高北抬,利于降水系统长时间停留在桂中桂北一带.特大暴雨区位于广西θse线相对密集区及拐点上,具备了高温高湿的不稳定条件.强降水发生在云项亮温TBB低值中心及TBB等值线密集区,且常发生在不断激发出的中β、γ云团中,小时雨量与TBB分布有较好的对应关系.

Quality of life of relatives of mental patients

Usage of quality of life of psychiatric patients' relatives as the parameter of estimation of the quality of psychiatric care is considered. By means of standard questionnaire elaborated by the authors as well as by means of both individual and group conversations the quality of life was analyzed in 40 relatives which lived together with psychiatric patients. Different spheres of their life and difficulties (financial, social-psychologic, production) were examined in families with such patients. The defects of psychiatric care that had direct influence on the quality of life of the psychiatric patients' relatives are outlined.     

Effect of antibiotics of chemotaxis of human leukocytes

The effect of 20 different antibiotics on chemotaxis by human neutrophils was studied. Human leukocytes incubated with chloramphenicol, rifampin, sodium fusidate, and tetracyclines in vitro showed markedly depressed migration. The mechanisms by which these antibiotics affect leukotaxis are discussed.     

Concept of freedom of infection of animal flocks

Totally negative results of epidemiological investigation of random samples do not prove the absence of the infection as the pathogen may be restricted to only a few animals in the herd for a long time. The statement "absence of infection" is critical for such situations. The question is raised, whether the statement "absence of infection" should be generally avoided. Classification of herds and flocks according to the prevalence of the pathogen would be more valid for the implementation of control measures.

The effect of amount of possession of the trait of hostility on accuracy of perception of hostility in others.

Some theories of personality hold that an individual's perception of others is influenced by his own personality characteristics; more specifically, that a trait of low social value will be projected more into others, and that insight into the possession of these characteristics reduces this distortion. These 2 hypotheses were tested by having a group of college students rate each other (including themselves) on degree of friendliness or hostility. Agreement with group rating about self yielded the insight score. In general, the hypotheses were supported; the "friendly" Ss were most accurate in their perception of others, and insight was positively associated with accurate perception.

Comparison of rates of infection of two methods of emergency ventricular drainage

The rates of infection of two methods of external ventricular drainage in use at Atkinson Morley's Hospital--namely, (a) percutaneous drainage with Rickham reservoirs and (b) tunnelled ventriculostomies--were compared in this retrospective review. Percutaneous drainage of CSF with Rickham reservoirs was associated with a 27% rate of infection as identified by positive microbiological cultures; tunnelled ventriculostomy catheters had a 10% infection rate. The difference in the infection rate between the two methods was statistically significant (P < 0.015). Other variables examined, including the age and sex of the patients and the reasons for ventricular drainage, were not associated with an increased rate of infection. Most infections from either method were caused by a coagulase negative staphylococcus. The average duration of ventricular drainage before identification of positive cultures was 5.7 days for Rickham reservoirs and 6.0 days for ventriculostomies.
