Today, in the field of computer networks, new services have been developed on the Internet or intranets, including the mail server, database management, sounds, videos and the web server itself Apache. The number of solutions for this server is therefore growing continuously, these services are becoming more and more complex and expensive, without being able to fulfill the needs of the users. The absence of benchmarks for websites with dynamic content is the major obstacle to research in this area. These users place high demands on the speed of access to information on the Internet. This is why the performance of the web server is critically important. Several factors influence performance, such as server execution speed, network saturation on the internet or intranet, increased response time, and throughputs. By measuring these factors, we propose a performance evaluation strategy for servers that allows us to determine the actual performance of different servers in terms of user satisfaction. Furthermore, we identified performance characteristics such as throughput, resource utilization, and response time of a system through measurement and modeling by simulation. Finally, we present a simple queue model of an Apache web server, which reasonably represents the behavior of a saturated web server using the Simulink model in Matlab (Matrix Laboratory) and also incorporates sporadic incoming traffic. We obtain server performance metrics such as average response time and throughput through simulations. Compared to other models, our model is conceptually straightforward. The model has been validated through measurements and simulations during the tests that we conducted.

Neonatal encephalopathy resulting from an asphyxial episode occurring perinatally is a major cause of death and of permanent neurological disabilities worldwide. Therapeutic hypothermia(TH) started within 6 hours of life and maintained for 72 hours is now well established as standard treatment for infants with moderate-to-severe hypoxicischemic encephalopathy(HIE).

　　德国摄影家安德烈亚斯·古尔斯基(Andreas Gursky)拍摄的都是诸如股票交易所、摩天大楼、叠嶂山峦等巨大空间的照片,在这些空间中的人们看起来渺小而不屑,仿佛微小而从容的蚁群.他们也正如蚂蚁一般,似乎无暇检视在这个自然界中已经占有的一切.摄影作品中的那些人,不知不觉却又坚定地表明,大自然中已不再有人类不曾触及的领域.当今,全球经济一体化入侵的陆标正在取代自然界的陆标位置,在整体上,古尔斯基的作品恰好绘制了这样一个后现代文明世界的地图.……

Mycotoxins are fungal secondary metabolites detected in many agricultural commodities, especially cereals. Due to their high consumption of cereals, pigs are exposed to these toxins. In the European Union, regulations and/or recommendations exist in pig feed for aflatoxins, ochratoxin A, fumonisins,zearalenone, and trichothecenes, deoxynivalenol and T-2 toxin. These mycotoxins have different toxic effects, but they all target the immune system. They have immunostimulatory or immunosuppressive effects depending on the toxin, the concentration and the parameter investigated. The immune system is primarily responsible for defense against invading organisms. The consequences of the ingestion of mycotoxin-contaminated feed are an increased susceptibility to infectious diseases, a reactivation of chronic infection and a decreased vaccine efficacy. In this review we summarized the data available on the effect of mycotoxins on the immune system and the consequences for pig health.
