海贝柱自动晾晒设备设计

针对当前传统人工晾晒海贝柱效率低下、容易造成污染等问题。设计了海贝柱自动晾晒机械,采用阶梯式晾晒生产线对湿海贝柱分级晾晒,多条晾晒生产线分时、高效的工作,机器上方设有遮板以保证晾晒作业不被污染而且不受天气条件的影响。整机采用stm32单片机、传感器等技术实现自动化作业,机器控制系统监测到生产线发生故障或海贝柱出现堆积时会立即停止工作以便于检查故障、减少损失。试验结果表明:机械晾晒不会造成海贝柱内的营养成分的流失,机械晾晒海贝柱的干基含水率达到30%仅需12h,机械晾晒海贝柱能节省大量的干燥时间,显著的提高了晾晒效率,避免了人工晾晒过程导致的二次污染和损失。该研究为海贝柱自动晾晒机械的研制提供了技术参考。     

农业信息：传统与现代的耦合

近年来，国家投资建设大量信息基础设施，以保证农业信息能更好的被农户采用。而现实中，农户并不通过网络、电视和报刊等现代信息手段获得农业信息，相反，基于地缘和血缘的熟人网络和以盈利为目的的商人成了农业信息传播的主要媒介。在这种传播方式下，农户的利益常遭侵害，农业科技难以广泛有效的传播，甚至一些假信息让农户失去了对“科技”的信赖。针对目前存在的种种问题，笔者兼顾现实与未来，提出了相关对策。     

苎麻属野生种的光反应类型研究

对苎麻属11个野生种资源进行了10h、13h、16h光照处理，在不同光长条件下，表现出短光照生育期缩短、长光照生育期延长；短光照生育期延长、长光照生育期缩短；长、短光照生育期都延长；长、短光照生育期都缩短四个类型，并且不同光照时间对不同的生殖生长期有不同的影响，生长发育的积温差异较大。     

伊维速克对普氏野马寄生虫的驱虫效果

使用伊维速克（伊维菌素制剂）对普氏野马进行驱虫，驱虫效果很好，与以前用的各种伊维菌素相比效果相近，但必需重复用药才能有明显效果。     

绵羊慢病毒自然感染绵羊的硬化性淋巴细胞性乳腺炎

７头来自新疆南部某绵羊慢病毒（ＯｖＬＶ）感染的羊场的绵羊用于本研究。用琼脂凝胶免疫扩散检查绵羊血清中对绵羊进行性肺炎（ＯＰＰ）病毒（ＯＰＰＶ）的抗体，结果表明有６例呈阳性，１例阴性，抗体效价在３年中呈下降趋势。４例血清学阳性边菜羊和１例阴性和田羊有不同程度的硬化性（纤维性）淋巴细胞性乳腺炎，小叶内有不等的淋巴细胞浸润，导管周围无淋巴滤泡形成，小叶间大量纤维组织增生。７例的肺、脑、关节、血管均无ＯｖＬＶ性特异性病变。从血清学阳性羊的外周血白细胞中未分离到ＯｖＬＶ。     

论法治与德治的辩证统一

法治既是一种治国方式和手段,也是人民行使管理国家、管理社会的权利的途径.德治的核心内容是要建立社会主义的道德体系和弘扬优秀的民族精神.法治和德治既有区别,又有联系,是辨证统一的.法治、德治的辩证统一是贯彻"三个代表"重要思想和建设中国特色社会主义的内在要求.     

The effect of eradication of lice on the occurrence of the grain defect light flecks and spots on cattle hides.

The influence of an eradication programme for lice on the prevalence of light flecks and spots on cattle hides was studied in 33 dairy cattle herds during a period of two and a half years. Lice were eradicated from the main group of herds after 9 to 12 months and the quality of the hides before and after treatment was compared. Hides from slaughtered animals were collected during the study period, tanned and examined with special emphasis on the occurrence of the grain damage light flecks and spots. The prevalence of hides without light flecks and spots increased from 24.2% before treatment to 61.6% after treatment. The prevalence of hides free from the damage increased significantly in all examined anatomical regions. The improvement in hide quality was most marked in the shoulders and neck region which corresponded to the major predilection site of cattle lice. The prevalence of hides with light flecks and spots started to decrease in the first period (2-40 days) after eradication. The changes after treatment suggested that most healing process took place over a period of about 4 months. The eradication programme eliminated the seasonal variation in the prevalence of light flecks and spots which was present before treatment.     

Sexual compatibility types of Bremia lactucae isolates originating from Lactuca serriola

Results are given on the occurrence of sexual compatibility types of seven isolates ofBremia lactucae originating fromLactuca serriola (prickly lettuce). It is concluded that the isolates studied are heterothallic. Both compatibility types (B1 en B2) were determined, but type B2 was prevalent. Sexual recombination ofB. lactucae isolates originating from wild and cultivated lettuce may occur.Samenvatting Zeven isolaten vanBremia lactucae, afkomstig vanLactuca serriola in Tsjechoslowakije, zijn onderzocht op hun sexuele compatibiliteitstype door ze te combineren met Nederlandse fysio's vanB. lactucae, afkomstig van cultuursla (L. sativa), waarvan het compatibiliteitstype (B1 of B2) bekend is. Alle isolaten vanL. serriola bleken heterothallisch te zijn, waarbij type B2 meer werd aangetroffen dan type B1. Sexuele recombinatie vanBremia-isolaten van wildeLactuca-soorten en cultuursla blijkt goed mogelijk te zijn.     

Serum 5'nucleotidase activity in rats: a method for automated analysis and criteria for interpretation

A manual kit for determining serum 5'nucleotidase (5'NT, EC 3.1.3.5) activity was adapted for use with rat samples on a large discrete clinical chemistry analyzer. The precision of the method was good (within-run C.V. = 2.14%; between-run C.V. = 5.5%). A comparison of the new automated method with a manual and semi-automated method gave regression statistics of y = 1.18X -3.66 (Sy. x = 4.54), and y = 0.733X + 1.97 (Sy. x = 1.69), respectively. Temperature conversion factors provided by the kit manufacturer for human samples were determined to be inaccurate for converting results from rat samples. Analysis of components contributing to normal variation in rat serum 5'NT activity showed age and sex to be major factors. Increased serum 5'NT activity was observed in female rats when compared to male rats beginning at about 5 to 6 weeks of age. An analysis of variance of serum 5'NT, alkaline phosphatase, and GGT activities observed over a 9-week period in normal rats suggests several advantages for 5'NT as a predictor of biliary lesions in rats.
