Lederer粘度模型适用范围

基于140组北疆—吐哈、胜利—阿曼混合原油的粘度测量数据,对Lederer模型(经验常数α使用印度Shu关系式)的适用范围进行了研究,发现应用该模型计算高粘度比混合原油粘度时,存在一个临界温度,当混合原油温度在临界温度以上时,Lederer粘度模型具有很高的预测精度,其最小平均绝对相对偏差为3.97%,最大平均绝对相对偏差为9.15%;当在临界温度范围以下时,Lederer粘度模型的预测精度明显变差,其最小平均绝对相对偏差为13.57%,最大平均绝对相对偏差为109.8%,无法满足工程需要。这个临界温度随混合原油组分、混合比例不同而不同,一般低于高含蜡组分油的反常点。另外,还发现Lederer粘度模型预测值的平均相对偏差几乎全部为负偏差,即大部分预测值小于实测值,表明经验常数α引用Shu关系式还有待于修正。

应用系统诊断方法,对科尔沁沙地系统的特征、存在问题及成因进行了分析,认为沙地系统衰退最根本的原因是政策、管理体制的不合理及科技人才的短缺;引起土地沙漠化的直接原因为急剧增长的人口、严重短缺的农村牧区燃料资源以及农业科技意识的淡薄.在此基础上还提出了沙地系统可持续发展的战略对策.     

Superficial digital flexor tendonitis in Thoroughbred race horses: outcome following non-surgical treatment and superior check desmotomy

Objective This study documents the results of non-surgical treatment and treatment by superior check desmotomy in Thoroughbred racehorses with superficial digital flexor (SDF) tendonitis. Design A prospective study was made of 124 thoroughbred racehorses with unilateral or bilateral SDF tendonitis. Procedure The flexor tendons were assessed by physical and ultrasonographic examination before treatment, and the lesions detected in affected tendons were characterised according to lesion type, length and cross-sectional area. Ninety three horses were managed non-surgically and 31 by superior check desmotomy. Recurrent or new injuries were defined as injuries affecting a previously injured superficial digital flexor tendon, the contralateral SDF tendon, or the suspensory ligament (interosseous muscle) in either forelimb. Results No statistically significant difference was found in ultrasonographic lesion severity between treatment groups. Horses managed by superior check desmotomy were 1.3 times more likely to complete five or more races than horses managed non-surgically (95% confidence limits 0.93–1.82). Horses treated surgically were 1.2 times more likely to develop recurrent or new injuries after returning to training than horses managed non-surgically (95% CL 0.95–1.55). Horses under-going superior check desmotomy were 5.5 times more likely to develop suspensory desmitis than horses treated non-surgically (95% CL 1.13–26.4). There was no difference in the time to recurrent or new injury between treatment groups. Conclusion There was no statistically significant difference between treatment groups in the proportions of horses able to complete five or more races after an episode of superficial digital flexor tendonitis. Superior check desmotomy did not appear to offer an advantage over non-surgical treatment in preventing recurrent or new injuries in Thoroughbred racehorses. Horses undergoing superior check desmotomy appeared to be at greater risk of developing suspensery ligament injuries than horses managed non-surgically.

Research Progress Towards the Liquid Chip Technology in Detection of Animal Infectious Diseases

Liquid chip technology is a novel biomolecular detection technology which integrates laser technology,flow cytometry,digital signal processing and traditional chemical technology.It is widely used in various immunological analysis and nucleic acid detection.Single and mutiplex analysis are supported,with protein and nucleic acid targets detected in a variety of detection methods in high throughput manner.It has advantages of high throughput,easy operation,wide range of application,good repeatability,high specificity,less sample needed,high sensitivity and stablility,and low cost.Therefore,they are gradually replacing the traditional detection and quantitative pathogen methods,such as Real-time fluorescent quantitative nucleic acid amplification detection system (qPCR),enzyme-linked immunosorbent assay (ELISA) and other detection methods.Animal infectious diseases seriously endanger the development of the breeding industry,futhermore,some zoonoses such as highly pathogenic avian influenza also pose a serious threat to human health.An efficient and sensitive diagnostic system will help to screen a large number of samples during the outbreak of infectious diseases and prevent the spread of infection.The development of liquid chip technology provides a new platform for high-throughput detection and disease prevention.In this review,the principle and advantages of liquid chip technology are briefly described.The research progress of liquid chip technology in the detection of animal infectious diseases,including pigs diseases,poultry diseases,rabbit diseases,dog diseases,rodent diseases and other animal infectious diseases are summarized.We believe that in the future,this technology will become an important analytical and testing tool in clinical diagnosis,basic research,new drug development,judicial identification,food health supervision,biological weapons prevention and other fields.The development of this technology will greatly promote the research and development of life science.
