indoor radon concentrations, the annual effective dose rate and the annual equivalent dose rate to the lung and to the public were measured in the dwellings of 10 neighborhoods located on the west side of the river tigris (al-karkh) in baghdad city using passive dosimeters. cr-39 solid state nuclear track detector (ssntd) technique was used for radon measurements. ninety-one dosimeters were dis...

STUDY OBJECTIVE To test the performance of a tool designed to estimate functional capacity in order to select a bicycle ramp protocol yielding a test duration from 8 to 12 min in healthy individuals, and to assess differences in exercise responses between bicycle and treadmill tests. PARTICIPANTS AND MEASURES Forty-one healthy and physically active volunteers (10 women; median age, 37 years; ...

High frequency digital LSIs usually consist of many subcircuits coupled with multi-conductor interconnects embedded in the substrate. They sometimes cause serious problems of the fault switching operations due to the time-delays, crosstalks, reflections and so on. In order to solve these problems, it is very important to develop a user-friendly simulator for the analysis of LSIs coupled with in...

Introduction: The risk of radioactivity addresses human life directly. The natural rock radioactivity is mainly due to 232Th, 238U), and 40K series. Activities involving blasting, crushing, and processing of rocks into numerous pieces lead to release of radionuclides into the atmosphere in the form of dust particles. M...

Twenty-five randomly selected, low or moderately fit and healthy women (22-44 years) rated their perceived physical capacity and performed an incremental cycle exercise test with respiratory gas analysis. The aerobic and functional capacity did not decrease with age. However, tauVo(2) increased with age. The mean value of the perceived physical capacity was 10 metabolic equivalents and that of ...

In this study, total phenolics and flavonoid compounds of methanol extract concentrations three medicinal plant, Asteraceae (Compositae) L. genus that are grown in Turkey belong to the Achillea, were determined with goal measuring their antioxidant activities. Antioxidant capacity was measured by widely used iron reducing power, DPPH radical scavenging activity metal chelating capacity. The act...

polycyclic aromatic hydrocarbons (pahs) in the priority controlling list of us epa weresystematically evaluated in surface sediments in dianchi lake and its estuaries. total pah concentrations(σpahs) varied from 210 to 11,070 ng/g dry weight (d.w.) in dianchi lake, and from 230 to 12,271 ng/g d.w.in the estuaries. σpahs in sediments from caohai section were higher than those from waihai section...
