“肥胖”弹响“肾脏损害四重奏”

在这个春光明媚的季节,人们脱去厚实的冬装,穿着缤纷绚丽的长裙短衣,尽情展示身材的曲线之美,无时无刻不在诱惑着人们的视线,而再美的服装都需要有窈窕的身材来作映衬, 这便是所有爱美人士不遗余力地在春季减肥塑身的原动力。从美学的角度看爱美人士减肥仅仅是为了有窈窕的身材、迷人的曲线;从医学的角度看肥胖除了给人带来生活上的不便之外, 就是肥胖还会给人带来高血压、高血糖(糖尿病)、高血脂、高尿酸等多种疾病。

HAVE A REST——欧宝卡车情景

正我对二战轮式车辆一直比较喜爱,而自己一直没有做过二战德军的卡车系列,在看了很多高手的卡车作品后自己也想开工一辆,我最终选择了制作一辆经典的欧宝3吨4×2卡车。欧宝卡车作为二战德军重要的轮式车辆,不仅产量很大而且根据不同的用途又衍生出了很多不同的型号,货厢版是最基本的欧宝3吨卡车,也是群众基础最好的一个版本,但正是因为做的人太多,对于我这种追求"个性"的人来说,做一个普通的货厢版无疑是缺乏吸引力的。为了让自己的欧宝卡车能别具一格,我查阅了一些欧

冯绍峰 八阿哥微博情

他曾经这样说:痴情的角色的确有一些就够了,我其实最想演的是混蛋,不过是善良的混蛋。可能他做的事情在普通人看来都是不好的,甚至有争议的,但他的内心和本质却是温柔善良的。我觉得这样的人物会更立体,有鲜明的特征,不仅真实也更有魅力。他是温文尔雅、风度翩翩的富家公子,他是痴情的年代戏第一小生,如今他又化身执著坚定的痴情阿哥。他是谁?他是冯绍峰。

影响香菇甲醛代谢的物质研究

过去的研究已证明香菇甲醛是由香菇子实体自身代谢产生的.影响香菇甲醛代谢的因素至今未有太多的文献涉及.通过向香菇子实体外部添加的方法,研究谷胱甘肽代谢途径的相关物质、含硫物质、生物信号分子及天然抗氧化物质等对香菇甲醛代谢的影响.试验结果表明:与谷胱甘肽代谢途径相关的物质均能显著地影响香菇甲醛的代谢.尤其是添加谷胱甘肽、半胱氨酸和谷氨酸的混合物,可使香菇甲醛的含量发生极显著地变化;含硫化合物中仅硫酸钠可以极显著地改变香菇甲醛的代谢;生物信号分子NO及天然抗氧化物质VC也能使香菇甲醛的含量与对照明显的不同.

Method validation for strobilurin fungicides in cereals and fruit

Strobilurins are a new class of fungicides that are active against a broad spectrum of fungi. In the present work a GC method for analysis of strobilurin fungicides was validated. The method was based on extraction with ethyl acetate/cyclohexane, clean-up by gel permeation chromatography (GPC) and determination of the content by gas chromatography (GC) with electron capture (EC-), nitrogen/phosphorous (NP-), and mass spectrometric (MS-) detection. Three strobilurins, azoxystrobin, kresoxim-methyl and trifloxystrobin were validated on three matrices, wheat, apple and grapes. The validation was based on recovery tests at three or four spiking levels, determined as double determinations and repeated three times (n = 6). The mean recoveries for the three detectors were in the range of 70-114%, and the LODs were between 0.004mg/kg and 0.014mg/kg, for all three strobilurins. The values for repeatability and reproducibility were within the limits for repeatability and reproducibility given by the Horwitz equation. Validation was not accepted for azoxystrobin in grapes on all three detectors and for azoxystrobin in apple for the MS-detector. A comparison of matrix-matched standards versus standards in solvent showed varying differences     

Three Times Daily Milking of Cows in California Dairy Herds

Twenty-eight California Holstein dairy herds were on twice daily milking for 3 to 17 mo and for 36 mo on three times daily milking. Effect of three times daily milking on yields of milk, fat-corrected milk, fat, and solids-not-fat, udder health, and reproductive performance was evaluated using Dairy Herd Improvement monthly herd summaries. Data for all cows in the herd and for first lactation cows were analyzed separately. Milk yield for the entire herd increased 12% above previous production on twice daily milking. Fat and solids-not-fat percentages were not affected by three times daily milking. First lactation cows milked three times daily yielded 14% more milk over previous twice daily levels. Fat percent was lower for first lactation cows on three time milking, but solids-not-fat percent did not change. Response to three time milking was not related to herd size or production while on twice daily milking. Udder health, evaluated by California Mastitis Test scores, and reproductive indexes were not affected by milking frequency.     

磷化氢点施药在粮堆中的运动分布

本文报告了采用小布袋埋藏法、探管投药法和磷化氢发生器仓外施药法点(局部)施药后磷化氢在散装粮堆中的运动分布情况。结果表明，在试验仓中三种方式施药后磷化氢的主要运动方向为施药点下方，向四周扩散比较少，在施药点上方几乎检测不到磷化氢气体。小布袋埋藏施药后基本在1～2d后施药点可测到浓度，磷化氢在施药点(主要在下方)滞留的时间约3～6d；探管施药时磷化氢在主要分布的施药点下方，在第8～10d后检测不出磷化氢，但总体浓度水平较低；用钢瓶装二氧化碳气体与发生器混合施入气体时，在施药点下方2h后即可检测到较高浓度，但1d后在施药点4m的范围内即基本检测不到磷化氢。

Corn silage management: effects of maturity, inoculation, and mechanical processing on pack density and aerobic stability

Three experiments were conducted to evaluate the effects of inoculation, maturity, and mechanical processing of corn silage on aerobic stability and pack density. Corn silage was stored in 20-L mini silos for the three aerobic stability experiments. Corn silage was stored in 80-L mini silos for the three pack-density experiments. The wet pack density of corn silage tended to decrease as maturity advanced in all of the pack-density experiments, and processed corn silage had a greater wet pack density compared with unprocessed corn silage in two of the three 20-L mini silo experiments. Aerobic stability, measured as the number of hours to reach 1.7 degrees C above ambient, was greater for processed corn silage in two of the three 20-L mini silo experiments, and was greater for inoculated corn silage across the three 20-L mini silo experiments. Inoculation of corn silage with lactic acid producing bacteria tended to improve aerobic stability of corn silage more than maturity and mechanical processing.     

Lactation Curves

Factors for adjusting beginning of lactation were developed for milk, fat, and protein yield. Records used were test day observations from New York and New Jersey from July 1982 through November 1983. Lactation curves were developed using a model that included fixed effects due to season by days in milk, days carried calf, age, and herd; random effects in the model included cow and error terms. A log transformation was performed on the data to account for a variance mean relationship for test day data. Analysis for the three yield traits was conducted for three lactation groups within five production groups. Lactation curves were estimated for six seasons of freshening by five production groups for three lactation groups for three yield traits, forming a total of 270 curves (90 for each trait). Lactation curves differed for three yield traits by production and season of freshening. Estimates of age and days carried calf, day of peak yield, and persistency estimates are presented for three yield traits stratified by herd production and lactation group. Plots of first lactation curves are presented for milk, fat, and protein for six seasons of freshening for lowest and highest production groups. An example of factors for different production groups and season of freshening are presented. Factors were too irregular to fit a regression equation. Factors developed were greater in magnitude than those currently used.
