Elevated temperatures in waste containment facilities
… facilities. A number of factors can lead to elevated temperatures and thus present a hazard to the public health and safety. For instance, MSW landfills can produce obnoxious odors, toxic gases, and aggressive leachates. In addition, they can damage gas extraction, leachate collection, …

Phonon hydrodynamic transport at elevated temperature
For over half a century, phonon hydrodynamic transport was deemed exotic and mattered only at extremely low temperatures. In this work, by combining the theoretical and experimental approach, we successfully predict and confirm the existence of phonon hydrodynamic transport in graphite above 200 K. …

Photovoltaic cell efficiency at elevated temperatures
In order to determine what type of photovoltaic solar cell could best be used in a thermoelectric photovoltaic hybrid power generator, we tested the change in efficiency due to higher temperatures of three types of solar cells: a polymer cell, an amorphous silicon cell and a CIS cell. Using an …

Genomic and biochemical investigation of soybean antioxidant metabolism in response to growth at elevated carbon dioxide and elevated ozone
… to continue rising in the future. The effect of elevated carbon dioxide concentrations on antioxidant metabolism varies among different studies in the literature. Therefore, the question of how antioxidant metabolism will be affected in the most realistic future atmosphere, with increased carbon …

The lubricating properties of graphite at elevated temperatures
The wear rate and the magnitude of friction of commercially available graphites in air have been shown to be dependent on the corrosion resistance of the graphite. In air the wear rate of graphite was observed to increase with increasing temperature up to 6000 C. A very rapid type of wear was found …

Personalized Feedback for Smokers with Elevated Anxiety Sensitivity
Objective: Cigarette smoking is the leading cause of preventable death and disability. The majority of smokers report a desire to quit and most make a serious quit attempt each year. Unfortunately, more than 95% of cessation attempters relapse within 6 months. Clinical and laboratory studies have …

Elevated temperature mechanical properties of line pipe steels
… by the steam assisted gravity drainage process. Elevated temperature tensile testing was conducted on commercially produced as-received plates at engineering strain rates of 1.67 x 10 4, 8.33 x 10 4, and 1.67 x 10 3 s 1. The acicular ferrite (X70) line pipe steels were also tested at elevated …
