Ambient concentrations and gas/particle partitioning of Polybrominated Diphenyl Ethers (PBDEs) were investigated in a industrial, a traffic and a background site in the urban agglomeration of Thessaloniki, northern Greece. Atmospheric (gas+particle) concentrations of ∑12PBDE at industrial site were higher than those observed at urban-traffic and urban-background sites. In industrial site, mean ...

OBJECTIVE To determine the efficacy of warm whirlpool, cold whirlpool, and contrast therapy in the treatment of delayed-onset muscle soreness. DESIGN AND SETTING Subjects performed eccentric contractions of the elbow flexors and received 4 treatments: immediately postexercise and 24, 48, and 72 hours postexercise. Treatments consisted of 24-minute treatments with warm whirlpool, cold whirlpoo...

The purpose of this study was to determine whether chronic cold exposure would increase the aerobic capacity of skeletal muscle in UCP-dta mice, a transgenic line lacking brown adipose tissue (BAT). Wild type and UCP-dta mice were acclimated to either warm (23 °C), or cold (4 °C) conditions. Cold increased muscle oxidative capacity nearly equivalently in wild-type and UCP-dta mice, but did not ...

A succession of Late Campanian- Early Maastrichtian is analyzed from Gurpi Formation with regard to the calcareous nannofossils. Correlation Matrix was applied for the first time to the entire nannofossil assemblage to reconstruct environmental conditions. A detailed quantitative calcareous nannofossil analyses is performed on samples in order to further investigate the climate events, and inte...

[1] The winters of 2009–2010 and 2010–2011 brought frigid temperatures to parts of Europe, Russia, and the U.S. We analyzed regional and Northern Hemispheric (NH) daily temperature extremes for these two consecutive winters in the historical context of the past 63 years. While some parts clear ly experienced very cold temperatures, the NH was not anomalously cold. Extreme warm events were much ...

INTRODUCTION Cardiac surgery involves cardiopulmonary bypass during which the core temperature is generally lowered to hypothermic levels. Patients presenting for cardiac surgery are sometimes reported to have cold or warm autoantibodies at the time of blood screening. It is known that cold agglutinins may cause potentially life-threatening haemolysis, intracoronary haemagglutination leading to...

We use a factorial experimental design to test whether rearing at colder temperatures shifts the lower thermal envelope for flight of Drosophila melanogaster Meigen to colder temperatures. D. melanogaster that developed in colder temperatures (15 degrees C) had a significant flight advantage in cold air compared to flies that developed in warmer temperatures (28 degrees C). At 14 degrees C, col...

The non-feeding postlarva (puerulus) of spiny lobsters actively swims from the open ocean to the coastal habitats where it settles and molts to the first-stage juvenile (JI). Because pueruli use much of their energy reserves swimming and preparing for the post-settlement molt, the survival of JIs presumably depends on resuming feeding as soon as possible. To test this hypothesis, the resistance...

The formation and evolution of galactic disks are complex phenomena, where gas and star dynamics are coupled through star formation and the related feedback. The physical processes are so numerous and intricate that numerical models focus, in general, on one or a few of them only. We propose here a numerical model with particular attention to the multiphase nature of the interstellar medium; we...
