虞城气象灾害与区域经济发展研究

利用1959～2010年虞城气象档案历史资料,总结分析了该县气侯特点、主要气象灾害以及与区域经济发展的关系等.结果表明,虞城属大陆性季风气候,具有四季分明、雨热同期、旱涝不均,气象灾害频繁的特点,经常发生的有暴雨、大风、寒潮、连阴雨、高温等原生气象灾害和内涝、干旱等次生气象灾害,全县气象灾害每年造成的损失占自然灾害造成损失总数的70%以上,约占全县国民生产总值的3%～6%,对虞城经济发展造成了严重的危害.同时提出了气象灾害防御措施.     

沈阳沈北新区蔬菜大棚生产期气候变化及气象灾害对策

[目的]研究沈阳沈北新区蔬菜大棚生产期气候变化及气象灾害对策.[方法]利用沈阳沈北新区近38年气象观测资料,采用常规数理统计方法,分析沈北新区蔬菜大棚生产期气候变化,并探讨气象灾害天气的应对措施.[结果]近38年来,沈北新区光照条件一般,冬季平均日照时数较短(551 h),呈缓慢减少趋势,但降幅并不明显;沈北新区蔬菜大棚生产期气温倾向率0.371 ℃/10 a,冬季气温倾向率0.313℃/10 a,气温虽呈升高趋势,但波动幅度较大,让生产管理难以控制;较寒冷期(11～3月)历年降水量、阴天日数呈增加趋势,对蔬菜大棚生产影响较大;低温寡照阴天是该区冬季气候特点,对发展蔬菜大棚产业不利,冬季增加取暖措施有望正常发展.[结论]研究结果可为当地设施农业的发展提供科学依据.     

邯郸农业气象灾情分析与评估

基于<邯郸市统计年鉴>1994～2007年有关数据统计资料,对邯郸市的主要农业气象灾害及综合灾情进行统计分析,并就气象灾害对粮油棉产量影响做灰色关联度分析.结果表明,1994～2007年邯郸农业因气象灾害造成的总受灾率和总成灾率呈现出波动性下降趋势,灾损严重年份农业总产基本也呈减产趋势,灾害性天气直接影响着农业生产;干旱造成的农业受灾面积最大,风雹造成的灾害次之.灰色关联度分析表明风雹灾对邯郸粮油棉产量造成的影响程度最大,其次为旱灾和水灾;气象灾害造成的农业受(成)灾面积与农业产量之间无明显的正相关关系.

高青2009年气象观测站温度对比分析

利用2009年高青国家气象观测站及6个区域气象观测站温度数据,对月、季平均气温、最高气温、最低气温及气温日较差进行了统计,分析各区域站点的温度差异,探讨各个区域的小气候特征.结果表明,唐坊区域气象观测站(县城东部)平均气温在2、5月份略高于其他区域,青城区域气象观测站(县城西部)3、4、10、12月份略高于其他区域,赵店区域气象观测站(县城东北部)平均温度在6～8、11月份略高于其他区域,黑里寨属于偏冷区域;而国家气象观测站平均温度相对偏低,这与测站四周比较空旷的环境有关.

Benzimidazole resistance in cyathostomes in horses in the Ukraine

The efficacy of treatment with cambendazole was tested in 1-year-old horses on a farm in Dubrovka, Ukraine. Thirty-five horses were treated. Their egg output was compared on the day of treatment and 14 days later with that of 33 untreated horses. Before treatment the mean number of eggs g-1 faeces was 614 in the controls and 766 in horses that had been treated. After 14 days the mean egg output in the controls was 580 and in the treated horses 369. This means a reduction of 54.5%. Only cyathostome larvae could be cultured from faeces collected after treatment. It can be concluded that benzimidazole resistance in cyathostomes is present in the Ukraine.

Fractures in childhood in Khartoum

A prospective study of fractures in 231 children received at Khartoum North Teaching Hospital(KNTH) was carried out for a period of six months. The incidence of child fracture rated as one per day, then it increased from the age of 5 years onwards in boys and between 6 and 8 years in girls. Most injuries were sustained during the day time, especially between late afternoon and sunset. 82% of injured children presented to a medical facility, while 18% were taken to native healers first. Non-road traffic accidents accounted for 84% of the fractures mainly due to sports, domestic injuries and falls; whereas road traffic accidents were 16% and occurred mainly in pedestrians. Forty three percent of the fractures needed only first aid and splintage while 42% needed closed reduction. Thirty one percent of all patients were treated as inpatients. The long bones were affected in 91% of all fractures, the commonest site being the distal end of the forearm (26%), followed by supracondylar fracture of the humerus (15.6%). In the upper limb, left-sided fractures predominated. The epiphyseal injuries were 3.5% of all fractures, mainly at the distal radial epiphysis. Boys were commonly affected between 13-15 years of age. Open fractures constituted 9.8% of the series and were mainly due to traffic accidents in town dwellers, the most vulnerable bones were those of the leg and foot. Pathological fractures accounted for 2.2% and were due to bone cysts and osteogenesis imperfecta. The problem of child safety and the preventive measures need to be more stressed.     

Apoptosis in experimental myocardial infarction in situ and in the perfused heart in vitro

We report the appearance of apoptotic cells in experimental myocardial infarction (rabbit heart) in in situ and in vitro preparations. Apoptosis was recognized by intravital staining with Hoechst 33342 (Ho342), by nick-end labeling (TUNEL) and by DNA laddering. A steady rise in the relative number of apoptotic cardiomyocytes (apoptotic index) was noted in in situ preparations. Apoptosis was first noted 6 h after the onset of ischemia with its highest value occurring after 72 h. Apoptotic nuclei were absent in remote areas of the left and right ventricles. Apoptotic nuclei within the infarcted area showed diminished intensity of Ho342 fluorescence. Three days after ischemia, a border zone adjacent to the infarcted area consisting of apoptotic macrophages was recognized. A novel finding was the appearance of apoptotic cardiomyocytes in the isolated perfused ischemic heart. Occurring as early as 50 min after the onset of ischemia, a high apoptotic index was present adjacent to the ligature placed around the coronary artery. This observation provides the opportunity to selectively examine factors leading to apoptosis in the ischemic heart under controlled experimental conditions.     

Botulism in Poland in 1996

A model is presented in which ion translocation through the F0 part of the ATP synthase drives the rotation of the ring of c subunits (rotor) versus the a subunit (stator). The coupling ion binding sites on the rotor are accessible from the cytoplasm of a bacterial cell except for the c subunit at the interface to the stator. Here, the binding site is accessible from the periplasm through a channel formed by subunit a. In the ATP synthesis mode, a coupling ion is anticipated to pass through the stator channel into the binding site of the adjacent rotor subunit, following the electrical potential. Occupation of this site triggers, probably by electrostatic forces, the rotation of the ring. This makes the binding site accessible to the cytoplasm, where the coupling ion dissociates. Simultaneously, this rotation moves again an empty rotor subunit into the contact site with the stator, where its binding site becomes loaded and rotation continues.     

Problems in falling in love

Certain patients enter psychoanalysis because of their inability to love another person. Often they report a repetitive erotic pursuit of desired partners, without being able to experience or maintain loving feelings. Kernberg has understood such difficulties as representing effects of early narcissistic disappointments and/or of difficulties in resolving oedipal conflicts. In this paper, Lacanian concepts of the mirror phase and symbolic love are employed to develop these issues. Sexualization of problems in mirroring may be fused with oedipal conflicts in some cases. An extended vignette is presented to illustrate the technical and theoretical issues.
