Incidence of bacterial pathogens in equine uterine swabs, their antibiotic resistance patterns, and selected reproductive indices in English thoroughbred mares during the foal heat cycle
equine endometritis antibiotics
2015/11/26
Fertility problems of mares on a well-managed breeding farm with thoroughbred stallions have been
ascribed mostly to contamination of the reproductive apparatus of females with pathogens, particular...
An empiric equation for the latent heat of vaporization of moisture in bananas during its isothermal drying
Energy Agricultural Products Dried Banana Heat and Mass Transfer
2013/2/28
In order to determine the energy needed to artificially dry a product, the latent heat of vaporization of moisture in the product, hfg, must be known. Generally, the expressions for hfg reported in th...
热激法修饰瑞士乳杆菌的参数优化与特性研究（Parameters Optimization and Properties for Lactobacillus helveticus by Heat-shock Treatment）
瑞士乳杆菌 热激处理 特性
2009/9/11
采用不同热处理温度(67、70℃)与时间(10、15、20s)对瑞士乳杆菌（Lactobacillus helveticus）进行热激修饰，研究处理前后与干酪加工相关的菌体特性，同时对热激修饰条件参数进行优化。研究结果表明，菌体经70℃、10?s热激处理后，菌体存活率、动态产酸能力、蛋白水解能力等指标符合热激要求，经修饰后的菌株适宜作为干酪促熟酶源。采用扫描电镜对细菌表面微观结构的观察结果表明，热...
Changes in Acetylcholine-Hydrolyzing Activity in Heat-Stressed Plant Cultivars
ACh-hydrolyzing activity Cucumber Heat stress Radish Yard-long bean
2009/8/4
The differences in the acetylcholine (Ach)-hydrolyzing activity in tessues and the changes in the enzyme activity after heat stress in yard-long bean, cucumber and radish plaants were determined. Spec...
The stress of rising natural gas prices is leading many consumers to rethink how they heat their homes. For some this means moving towards modern alternative energy options, while others have been tu...
