There is increasing interest in electromagnetic interference (EMI) shielding due to the serious electromagnetic environment pollution caused by the continuously increased use of the electrical products and electronic devices. Electrical conductivity and EMI shielding effectiveness (SE) of composite materials made from silicone rubber with carbon powder and ferrite powder have been studied in mi...

BACKGROUND AND OBJECTIVE Modeling of light transport in tissue requires development of theoretical models and experimental procedures, as well as tissue-simulating phantoms. Our purpose was to develop a phantom that matches the optical characteristics of human skin in the visible and near infrared spectral range. STUDY DESIGN/MATERIALS AND METHODS The phantom consists of a transparent silicon...

Biocomposites is a field that has gained much scientific attention due to the current substantial consumption of nonrenewable resources and the environmentally harmful disposal methods required for traditional polymer composites. Research on natural fiber reinforced polyhydroxyalkanoates (PHAs) has gained considerable momentum over the past decade. There is little work on PHAs reinforced with u...

Tribological properties of Ethylene-Propylene-Diene-rubber (EPDM) containing electron modified Polytetrafluoroethylene (PTFE) have been investiagted with the help of pin on disk tribometer without lubrication for a testing time of 2 hrs in atmospheric conditions at a sliding speed and applied normal load of 0.05 m·s–1 and FN = 1 N, respectively. Radiation-induced chemical changes in electron mo...

There is lack of data on the prevalence of latex allergy in the health care setting in Iran. This study was performed to determine the prevalence of type I latex allergy and type IV allergy to latex and rubber additives among the operating room staff with glove-related symptoms in 13 general hospitals in Tehran. Skin-prick tests with commercial latex extract, patch tests with latex and 25 rubbe...

Exposure to starch powder from both surgical and examination gloves can cause a number of undesirable reactions, which vary from well known allergy symptoms and upper respiratory-tract disorders to pleuritis, myocarditis, irritation of the central nervous system or even carcinoma or tuberculosis misdiagnosis. A well documented consequence of the use of starch powder in gloves is its capacity to...
