hypersensitivity reactions to natural rubber latex have increased recently, especially among people with high exposure to latex allergens. hypersensitivity reactions to latex are related to many conditions like occupational asthma. our study was performed to determine the prevalence of hypersensitivity to natural rubber latex and potential food cross reactions in operation room personnel in shi...

The decreasing cost of solar photovoltaics (PVs) and battery storage systems is driving their adoption in the residential distribution system, where more consumers are becoming prosumers. Accompanying this trend potential roll-out home energy management (HEMSs), which provide a means for prosumers to respond externalities such as price, weather, demands. However, economic operation can affect g...

The teaching management system of higher vocational institutions is to organize, plan and control the work teachers, ensure that students can obtain corresponding credits abilities in learning process, which plays an important role improving quality talents. At present, China's education facing a serious complicated situation. Based on this background, paper puts forward series innovative refor...

in this paper, dynamical behavior of the delay mechanism of a special projectile controller is studied, using 3d finite element simulation. the controller considered here is among of high-acceleration mechanical controllers. due to high linear and angular accelerations of the projectile and also explosion risk, experimental investigation is very limited and almost impossible. so, numerical simu...

the present work studied the application of membrane bioreactor (mbr) for tapioca wastewater processing that contained chemical oxygen demand (cod) ranging from 4000-9000 mg/l. a preliminary study was initially conducted in order to evaluate membrane performance with respect to its flux with mlss concentration ranging from 4,500 to 10,500 mg/l. it was clear that fouling was observed during the ...

Typical training simulation systems adopt distributed network architecture designs composed of personal computers because of cost, extensibility, and maintenance considerations. In this design, the functions of the entire system are easily affected by failures or errors from any computer during operation. Thus, adopting appropriate fault-tolerance processing mechanisms to ensure that the normal...
