However, it is not a routine test for all patients and, as a result, many patients are not aware of their HIV status. To understand the rate of HIV infection and the factors associated with infection, we tested serum to determine HIV status and analyzed factors associated with HIV infection. Methods We...
In China, several species (Hedysarum polybotrys Hand.-Mazz., Hedysarum limprichtii Hlbr., Hedysarum vicioider Turcz. var. Taipeicum Hand.-Mazz. Liu, Hedysarum smithianum, et al.) of genus Hedysarum have a long history of use in traditional Chinese medicine (TCM). In TCM, these plants are used to increase the energy of the body.

Java is one of the most popular programming architectures because of its platform-independence. Its platform-independence depends on Java virtual machine JVM. Compared to executing class file on hardware JVM, executing class file on software JVM is much slower. By studying we master the component architecture and the working principle of software JVM based on the class file to explain the implementation...
This paper presents a method to design the shading coil in electromagnetic mechanism of AC contactor using ANSOFT Maxwell 3D. Taking CJ20-25 AC contactor as an example, the FEA model of electromagnet in AC contactor was established, and the contour of magnetic field density of electromagnet was worked out. The influence on magnetic force was also studied when the width and thickness of cross area...
