abstract background and objective: proficiency testing schemes as a part of quality system in clinical and research laboratory centers provides the opportunity to evaluate the quality of test results. in this paper, we try to introduce the proficiency testing schemes as a useful method for achieving standardization and homogenization of test results in clinical and research laboratory centers. ...

background pandemic flu is a concerning problem with potentially high mortality and morbidity rates, so needs a proper health system response in each country. objectives to evaluate the nationwide health system response in iran after declaration of h1n1/swine flu pandemic in june 2009. patients and methods a surveillance system in all regions of country was implemented upon declaration of pande...

is an implementation of a three-level computer hierarchy that provides a high degree of perjormance, availability, and ease ($use for laboratory automation applications. Laboratory automation, a subset of sensor-based computer use, is an area of computer application that is characterized by the computer elements servicing user-attached devices. These are usually devices such as instruments, tes...

In an effort to minimize the risks for scientists exposure to the infectious environment and avoiding infectious incident, high-level bio-safety laboratories are designed and constructed to improve experimental safety by preventing laboratory infectious waste causing harm to people or the environment. The possibility of high-risk pathogens spread to the public environment with flow of people an...

We propose a novel population-based optimization algorithm, Chaotic Evolution (CE), which uses ergodic property of chaos to implement exploration and exploitation functions of an evolutionary algorithm. CE introduces a mathematical mechanism into an iterative process of evolution and simulates ergodic motion in a search space with a simple principle. A control parameter, direction factor rate, ...

Quest Diagnostics is a large company that analyzes millions of medical specimens every day using a variety of analytical equipment. It is implementing a fully automated line in a major laboratory. The automation line is Quest's first major automation initiative and will serve as a pilot for future initiatives. An important element of implementing this initiative is the transition from manual to...
