高校勤工助学应从体力型转向智力型     

周海蓉 《四川畜牧兽医学院学报》2006,4(1):199-201

在国家建立的资助经济困难学生的奖、贷、助、补、减政策体系中，勤工助学具有独特的地位和作用。随着社会的发展，体力型勤工助学已经越来越不能满足贫困学生的需要。要想完全发挥勤工助学的作用，必须将勤工助学从体力型转向智力型。  相似文献   

万州区农业产业化、农村工业化、农村城镇化发展不协调的表现研究     

谢必武徐小方  周长春杨洪霞  潘久政冯梅 《四川畜牧兽医学院学报》2006,4(2):124-127

通过大量调查，分析了万州区农业产业化、农村工业化、农村城镇化发展不协调的表现。具体表现在：农业产业化与农村工业化发展不协调，工业化程度偏低，农业产业化程度不高，没有形成规模经济和产业链；农业产业化与农村城镇化发展不协调，影响市场容量的扩大，制约农业自身的发展，制约第三产业发展和农民进入城镇就业步伐，城镇化辐射带动能力弱；农村工业化与农村城镇化发展不协调，城镇对生产要素的集聚功能差，农村工业布局较分散且技术落后，“空城现象”明显；农业产业化、农村工业化、农村城镇化与区域经济发展不协调，区域经济发展水平不高，区域经济结构运行质量不高，区域经济的市场竞争力不强，区域经济的发展环境不优。  相似文献   

协力构建和谐的医患关系     

张国栋 《四川畜牧兽医学院学报》2006,4(3):52-55

和谐的医患关系是社会主义和谐社会的重要内容.构建和谐的医患关系,需要政府、医院、医务人员和患方的共同努力.为此,政府应增加卫生经费投入,加快卫生立法步伐;医院应着力医德医风建设,正确处理医疗纠纷;医务人员应树立人文关怀理念,改善医疗服务态度;患方应科学认识就医行为,理性对待医疗事故.  相似文献   

绒山羊KAP13-1基因在毛囊中的表达     

李长青  李玉荣  尹俊  马跃军  高玉林 《中国草食动物》2006,(Z1):111-114

绒山羊绒毛的主要结构蛋白是角蛋白和角蛋白关联蛋白(KAP).对绒山羊13-1的序列分析可知,其与人、鼠的KAP13家族cDNA同源性较高,但氨基酸序列同源性较低,而且丝氨酸含量高,半胱氨酸及甘氨酸/酪氨酸的含量远低于其他品种,分类上属于高硫KAP家族;绒山羊兴盛期毛囊KAP13-1的mRNA原位杂交也显示,KAP13-1只在毛母质上部和皮质层起始部分表达,且表达强烈.  相似文献

Effects of pheromone loading, dispenser age, and trap height on pheromone trap catches of the oriental fruit moth in apple orchards     

Orkun B. Kovanci  Coby Schal  F. Walgenbach  George G. Kennedy 《Phytoparasitica》2006,34(3):252-260

The effects of field aging (0–28 days) and pheromone loading rate on the longevity of red rubber septa loaded with the sex pheromone blend of the oriental fruit mothGrapholita molesta (Busck), were evaluated in North Carolina apple orchards in 2002. Separate field tests examined the influence of trap height and pheromone loading rate of rubber septa on trap catches of adultG. molesta males in an abandoned orchard. The loss of the major pheromone component, (Z)-8-dodecenyl acetate (Z8–12:OAc), from red rubber septa over a 4-week period exhibited a relatively constant release rate with 30, 100 and 300 μg pheromone. Trap catch was significantly higher in pheromone traps placed in the upper canopy than in those in the lower canopy. Pheromone traps baited with 100μg lures caught more moths compared with those loaded with 300 μg. There was no apparent relationship between pheromone trap catch and septa age, with trap catch appearing to be primarily a function ofG. molesta population density. http://www.phytoparasitica.org posting May 14, 2006.  相似文献

Use of β-Glucanases and β-1,4-Xylanases to Supplement Diets Containing Alfalfa and Rye for Laying Hens: Effects on Bird Performance and Egg Quality     

《The Journal of Applied Poultry Research》2006,15(2):256-265

It is well established that the use of alfalfa in diets for monogastric animals is limited by its high fiber content. However, alfalfa is a natural source of xanthophylls and gives poultry products a desirably yellow color. In addition, alfalfa saponins may contribute to reduce the levels of cholesterol in the meat and egg yolk. We have investigated the potential utilization of β-glucanases and β-1,4-xylanases for enhancing the nutritive value of alfalfa for laying hens. An experiment was conducted with 864 ISA Brown layer hens from 40 to 52 wk of age and fed on diets containing rye (19.6%) or rye and alfalfa (15.1%). The results suggested that inclusion of alfalfa in the diets reduced body weights and total egg mass (P < 0.01). Dietary supplementation with polysaccharidases was unable to significantly improve the performance of laying hens. However, egg yolks from birds that consumed diets containing alfalfa were more deeply pigmented, presenting an increase in yellowness (b*). In contrast, at the percentage of incorporation tested, inclusion of alfalfa in the diets was unable to lower the levels of cholesterol content in the egg yolk. Taken together the results suggest that exogenous plant cell wall hydrolases are not effective for improving the nutritive value of alfalfa-containing diets for laying hens, although inclusion of small percentages of the dehydrated leguminous meal may directly affect the quality of the generated poultry products.  相似文献   

不同品种厚皮甜瓜果实成熟过程中挥发性物质成分分析   总被引：16，自引：1，他引：16  

唐贵敏  于喜艳  赵登超  王利平 《中国蔬菜》2007,1(4):0-7

采用固相微萃取(SPME)与气相色谱-质谱(GC-MS)联用的方法,对品质差异较大的山农黄金1号、Sweet delight(美国)和Takami(日本)厚皮甜瓜果实成熟过程中挥发性物质进行分析鉴定。结果表明,不同品种厚皮甜瓜果实成熟过程中挥发性物质组成和相对含量不同。山农黄金1号、Sweet delight和Takami果实成熟过程中共分离出156种挥发性物质,主要为酯类、醛类和醇类等化合物。山农黄金1号甜瓜果实未成熟时挥发性物质以醛类物质为主;随着果实的发育,近成熟时醇类、醛类物质含量急剧降低,酯类物质含量迅速升高;果实成熟时挥发性物质以酯类物质为主。Sweet delight果实未成熟时挥发性物质以醛类、醇类物质为主;随着果实的发育,醇类物质含量逐渐降低,醛类、酯类物质含量逐渐升高;果实成熟时挥发性物质以醛类物质为主。Takami果实未成熟时挥发性物质以醇类、醛类物质为主;果实成熟时挥发性物质以酯类、醛类物质为主。  相似文献
