in this paper, vacuum assisted resin transfer molding (vartm) method was simulated by analytical solution. then the effect of parameters like fiber density, distribution of layer thickness, perform layer thickness, resin viscosity was investigated theoretically. obtained results show that by selecting optimum distribution layer thickness, increasing fiber volume fraction, reducing viscosity of ...

conclusions the addition of 50 mg of magnesium sulfate to a bupivacaine–fentanyl solution for intrathecal anesthesia improved the efficacy and duration of the analgesia without any significant side effects. the addition of 150 µg of neostigmine increased the incidence of hypotension, bradycardia, and nausea and vomiting. moreover, neostigmine failed to prolong analgesia duration. results group ...

Lethal injections have been increasingly employed in China nowadays. Due to the lack of specific institutions in China’s legislation, there is no universal and definite standard for the options and execution procedure of lethal injections, causing lots of problems. Therefore, an option for lethal injections should be established and relevant execution procedure should be further improved as well.

This paper presents an approach for conformance testing and fault injection of distributed systems supported by a tool named FSoFIST (Ferry-clip with Software Fault Injection Support Tool). The approach extends the ferryclip concept to cope with fault injection. The ferry-clip concept was aimed at providing a highly modular, flexible and configurable architecture for protocol conformance testin...

Background: Dexmedetomidine, a selective ?2 agonist has shown promising results when used as premedicant. This prospective randomized study evaluated the efficacy of two different premedication regimens in achieving smooth conduct anesthesia and optimum pain relief pediatric cataract surgeries. Methods: 90 ASA I or II children, aged 1-6 years, scheduled for elective surgeries were to receive ei...

Vapor refrigerant injection cycle with a flash tank has proven to be effective in improving system performance significantly at extremely low and high ambient temperatures. However, the control strategy of operating the system is still unclear. There is no open publication on the comprehensive study of the vapor injection cycle control strategy to date. This paper presents the experimental inve...

Nowadays Heat pump water heater becomes a very hot topic in hot water industry. However it has many problems because of higher condensing temperature and large-scale operation conditions. Based on the problems, this paper presents a prototype which was assembled using a rotary compressor with refrigerant injection port. By making use of the liquid injection function of the compressor, the syste...
