Activating lignite and sludge by electro-hydraulic impulse

1. Introduction At present, it is necessary to use fertilizer to ensure the stable and high agricultural productivity. However, as we all know, the fertilizer not only decreases the self-fertility of soil, but also is accompanied with pesticide. Food poisoning caused by remnant pesticide in fruits and vegetables is often reported, and in such cases, chronic poisoning is the majority. The remnant pesticide accumulates in body gradually, and then induces kinds of disease. As reported, the Miyu…

新课程改革遭遇教师冷漠态度的文化审视

新一轮基础教育课程改革正在如火如荼地展开,但是对其成败起关键作用的我国广大中小学校教师中的部分教师,态度表现冷漠消极。这种现象有着深层的原因,我们可以从文化视角来审视,研究解决的策略。     

冷战之源

二战后出现的美苏之间的冷战是20世纪上半叶世界政治、经济、军事等方面发展的必然结果。它实际上是以美、苏为代表的两种政治力量、两种社会制度和意识形态的根本对立,是美苏两极格局的斗争,是二战后两个超级大国为争夺世界霸权而进行的斗争。     

精浆糖蛋白分析及其临床应用

本文报告了测定精浆糖蛋白总量及聚丙烯酰胺凝胶电泳分析糖蛋白组分的实验方法。对99例正常生育男性的精浆和96例男性不育症患者的精浆糖精浆糖蛋白总量蛋白总量进行了统计学处理。正常精浆糖蛋白总量为2.60±0.73g/dl,不育症患者为3.02±0 64g/dl,t=4.15.P<0.01。在96例不育症中有36例前列腺炎,18例小睾丸,10例副睾炎和6例精索静脉曲张,其糖蛋白总量分别为3.07±0.67g/dl,2.93±0.65g/dl,3.11±0.52g/dl 和2.63±0.92g/dl。与正常精浆相比,t 值显著性检验)分别为3.379(P<0.001),2.481(P<0.02),2.15(P<0.05)和0.095(P<0.05)。本文还对1例正常精浆和4例临床病因不同引起不育者的精浆进行了聚丙烯酰胺凝胶电脉分析,结果提示正常人与不育者在精浆糖蛋白组分上有很大差异,这种差异的临床意义还待进一步研究。

不同强度、不同方式运动对血浆内皮素的影响

采用特异性放免法测定运动员不同强度、不同方式运动前后外周血浆中内皮素 (ET)的含量 ,以探讨运动员运动时血浆 ET的变化规律。结果表明 ,不同强度、不同方式运动对血浆 ET的影响不同 ,运动强度越大 ,血浆 ET浓度增加越多 ,同时伴收缩压及血乳酸升高 ,并呈正相关 ,跑台力竭运动后血浆 ET浓度增加明显 ,而跑台恒负荷运动和自行车力竭运动不引起显著的血浆 ET的应答变化。提示运动是导致血浆 ET浓度升高的因素之一 ,升高程度具有运动强度的依赖性 ;同时 ,对于全民健身运动中锻炼者掌握适当强度的有氧运动而不致引起血压升高等身体不良反应提供了科学依据。     

The creatine content of Creatine Serum™ and the change in the plasma concentration with ingestion of a single dose

Three samples of Creatine Serum? ATP Advantage from Muscle Marketing USA, Inc. were assayed for creatine by two different techniques by four independent laboratories, and for creatinine by two different techniques by two laboratories. A further sample was assayed for phosphorylcreatine. Dry weight and total nitrogen were also analysed. Six male volunteers ingested in random order, over 3 weeks: (A) water; (B) 2.5?g creatine monohydrate (Cr?·?H₂O) in solution; and (C) 5?ml Creatine Serum? (reportedly containing an equivalent amount of Cr?·?H₂O). Blood samples were collected before and up to 8?h after each treatment and plasma was analysed for creatine and creatinine. Eight-hour urine samples were analysed for creatine. Ingestion of 2.5?g creatine monohydrate in solution resulted in a significant increase in plasma creatine (from 59.1±11.8?μmol?·?l^?1 to 245.3±74.6?μM μmol?·?l^?1; mean±s) and urinary creatine excretion. No increase in plasma or urinary creatine or creatinine was found on ingestion of Creatine Serum? or water. Analysis showed 5?ml of Creatine Serum? to contain <10?mg Cr?·?H₂O and approximately 90?mg creatinine. Phosphorylcreatine was not detectable and only a trace amount of phosphorous was present. Total nitrogen analysis ruled out significant amounts of other forms of creatine. We conclude that the trace amounts of creatine in the product would be too little to affect the muscle content even with multiple dosing.
