studies show that any complications including hemorrhage, lack of blood supply, lack of oxygen supply, and death of cells in a tissue, will have a clear effect on electrical properties of that tissue. thus, by measuring impedance of a set of tissues, potential problems of the damaged tissue may be found. since electrical impedance is closely related to the measuring frequency, obviously, every ...

Safety case development is not a post-development activity, rather it should occur throughout the system development lifecycle. The key components in a safety case are safety arguments. Too often, safety arguments are constructed without proper reasoning. Inappropriate reasoning in safety arguments could undermine a system’s safety claims, which in turn contributes to safety-related failures of...

Drugs, usually long acting and metabolically stable molecules, might be the source of adverse effects triggered by complex drug interactions, anaphylaxis and drug-induced coagulopathy. To circumvent this growing drug safety issue, we herein investigate the opportunity offered by bio-orthogonal chemistry for in vivo drug neutralization. We design a small-molecule anticoagulant drug (Warfarin) co...

Vehicular Ad-hoc Networks (VANETs) play main role in the design and development of the Intelligent Transportation Systems (ITS) who improves the road safety and transportation productivity. One of the most important challenges of this category of network are the timely, safely and reliable dissemination of messages between vehicular nodes to improve the road safety. Here in this paper PSO based...

background: bio-aerosols in the air of hospital wards have an important role in the development of infections. it is important to make quantitative and qualitative estimations of microorganisms in the air of these wards as an index for environmental hygiene applicable to different hospital wards. the aim of the study was to investigate degrees of diversity and density of bio-aerosols in the edu...

Dependability is an essential attribute for microfluidic biochips that are being developed for safety-critical applications such as point-of-care health assessment, air-quality monitoring, and food-safety testing. Therefore, these devices must be adequately tested after manufacture and during bioassay operations. This paper describes testing and diagnosis techniques for droplet-based "digital" ...

introduction: birth weight is one of the important sanitary indices in evaluating the prenatal care all over the world. the purpose of this research was to determine the relationship between the bio-environmental characteristics of mothers with infant’s birth weight. materials and methods: in corrolation study, first, all newborn babies in hospitals and maternity centers khuzestan between farwa...

Biometric information is used in a variety of industrial fields. Heart rate and respiration rate, particular, are widely applied not only medical institutions but also life safety. However, sensor must be worn or directly attached to the human body obtain bio signal, which inconvenient limits its application. In this study, 24 GHz radar module developed, an algorithm implemented by analyzing fr...

in order to study the effects of integrated application of bio-fertilizer and chemical fertilizers on yield and yield components of corn, an experiment was conducted in 2008 in dezful city, (khoozestan province) in a factorial arrangement based on complete randomized block design with four replications. treatments were integrated application of biological and chemical fertilizers in four levels...
