OBJECTIVE We determined the effects of coupling medium temperature on the rate of intramuscular temperature rise (RTR) during continuous ultrasound. DESIGN AND SETTING Ultrasound was applied in a continuous mode at a frequency of 1 MHz and intensity of 1.5 W/cm(2). Each subject received 3 treatments, using water-based coupling gel at temperatures of 18 degrees C, 25 degrees C, and 39 degrees ...

CDC is collaborating with the U.S. Environmental Protection Agency to urge U.S. residents to pay attention to their local air quality during Air Quality Awareness Week, April 28–May 2, 2014. May also is Asthma Awareness Month, and May 6 is World Asthma Day. Asthma sufferers are particularly affected by air pollution. One in 12 U.S. residents (approximately 25.5 million persons) currently has as...

Abstract This study aimed to examine the thermal environment in schoolyards under Mediterranean conditions, and impact of two interventions on amelioration bioclimatic conditions. The investigation was performed for three schools Athens, Greece, through microclimatic simulations by ENVI-met, a typical day June, evaluated based air surface temperature values. index Physiological Equivalent Tempe...

We have examined the interaction of photoperiod and temperature in regulating the parr-smolt transformation and its endocrine control. Atlantic salmon juveniles were reared at a constant temperature of 10 degrees C or ambient temperature (2 degrees C from January to April followed by seasonal increase) under simulated natural day length. At 10 degrees C, an increase in day length [16 h of light...

The aim of the studies was to determine the stability of metronidazole using UV spectrophotometric method in 0.5% w/w eye drops which were prepared under aseptic conditions and thermally sterilized. 0.9% solution of NaCl, 5% glucose and phosphate buffers of pH 6.97 and 6.81 were used as the solvents of metronidazole in the drops. Thiomersal and phenylmercuric borate were used to preserve the dr...

There is a great demand for safe and effective alternative fumigants to replace methyl bromide and other toxic fumigants for postharvest pest control. Nitric oxide, a common signal molecule in biological systems, was found to be effective and safe to control insects under ultralow oxygen conditions. Four insect species including western flower thrips, Frankliniella occidentalis (Pergande) (Thys...

The Late-Quaternary climate of Beringia remains unresolved despite the region's role in modulating glacial-interglacial and as likely conduit for human dispersal into Americas. Here, we investigate Beringian temperature change using an ?32,000-year lacustrine record leaf wax hydrogen isotope ratios (?2Hwax) from Arctic Alaska. Based on Monte Carlo iterations accounting multiple sources uncertai...

Key-words: temperature, ecological optimum, Cladocera, stepwise changes, prolonged effects, realized niche Laboratory experiments with natural zooplankton communities were carried out to study the effects of two contrasting temperature regimes: constant temperature (15, 20, and 25 ◦C) and graded changes in temperature. The graded regime consisted of repeated sustained (three weeks) controlled s...

Climate change factors interact to modify plant growth and development. The objective of this study was to evaluate the response to temperature of big bluestem (Andropogon gerardii Vitman) development, growth, reproduction and biomass partitioning under low and high carbon dioxide concentrations ([CO2]) grown in controlled environmental conditions. Ten sunlit soil–plant–atmosphere-research (SPA...

in this research work, the dissolution of chalcopyrite was investigated under atmospheric pressure, with sulfate media at low temperatures, in 30°c to 50°c. in the galvanic interaction between chalcopyrite and pyrite, pyrite is used as a leaching catalyst. effects of different parameters such as temperature, stirring speed, pyrite to chalcopyrite ratio, particle size, and solution potential wer...
