An Efficient Simulation-Based Optimization Approach for Improving Emergency Department Performance.

In recent years, health care organizations, in particular emergency department (ED), have come under increasing pressure to provide quality care. In this context, human resources are a central aspect: a good utilization of health worker could improve quality of care. In this paper, a simulation model is proposed.

Laboratory environment and bio-medical experience: the impact of administration technique on the quality of immune-behavior data results in stress experience.

Introduction: Often in an experiment, the control group and the intact group are not identified because most scientists neglect the fact that the sets of manipulation as technical administrations may be considered as an undesirable stress on the clarity of the data obtained from a scientific research specifically if it focuses on studying the effects of stress.

Methods: This study was conducted in two parts using 40 male Wistar rats. The first part aimed to treat a group of rats by repeated injections i.
