Private equity performance, both for buyouts and venture capital, has been highly cyclical: periods of high fundraising have followed by low performance. Despite this seemingly predictable variation, we find modest gains, at best, to pursuing realistic, investable strategies that time capital commitments private equity. This occurs, in part, because investors can only their funds; they cannot w...
radar transmitters emit high-power radiofrequency radiation by creation of a high-voltage and high-frequency alternating electrical current.health effects of occupational exposure to military radar were investigated. visual reaction time was recorded with a simple blind computer-assisted-visual reaction time test. to assess the short-term memory, modified wechsler memory scale test was performe...
background: dielectric barrier discharge (dbd), a source of non-thermal plasma, is used in surface decontamination. objective: to study the effect of dbd plasma treatment, we evaluated the effect of plasma exposure time on inactivation of bacillus subtilis. results: applying the dbd plasma to the culture of b. subtilis caused complete sterilization of the surface without any thermal effects. in...
introduction: nickel (ni) is one of the toxic heavy metals that exposure to it has been connected with chronic respiratory complications such as asthma, chronic bronchitis, lung cancer and heart disease. in this research, original studies that investigated occupational or environmental exposure to nickel and measured nickel levels in human tissues were reviewed. materials and methods: in this ...
glutaraldehyde is commonly used in endoscopy labs to clean and disinfect instruments. it can cause direct irritation of the skin and the upper and lower airways. health care workers are also at risk for the development of irritant-induced or sensitizer-induced occupational asthma when exposed to this chemical. herein, we report on a patient who had frequent exposures to glutaraldehyde over one ...
introduction: patients administered with a therapeutic dose of 131i for thyroid cancer treatment are potential sources of unacceptably high radiation exposure to other individuals, particularly the patient's immediate family members. the aim of this study is to investigate effects of early liothyronine consumption after radio-iodine therapy on accumulated dose and exposure rate in patients with...
Introduction: The increasing use of electromagnetic field generators in our daily life in one hand and on contradictory reports on the effects of their waves on public health on the other hand encourages scientists to do more and more research work in this field. One of the most important topics is the study of gene defect due to microwave radiation. Materials and Met...
