Mobility and Saturation Velocity in Graphene on Silicon Dioxide
… as a function of carrier density at temperatures from 300 to 500 K. In addition, electron drift velocity is obtained at high electric fields up to 2 V/μm, at both 80 K and 300 K. Mobility displays a peak vs. carrier density and decreases with rising temperature above 300 K. The drift …

Interactive effects of diel-cycling hypoxia, pH, and temperature on growth of Fundulus heteroclitus, a common estuary-resident fish
… of Fundulus heteroclitus was examined at three temperatures in several treatments of diel-cycling DO and pH. Diel-cycling pH (ranging either from 7.2-7.8 or 6.8-8.1) at 25°, 30° and 35°C did not significantly affect growth. However, wide ranging diel cycles in DO (1-11 mg O2 l-1 but not 3-9 mg …

The effects of the macroalga Gracilaria gracilis and increasing temperatures on the performance of the endemic Cape eelgrass Zostera capensis
Rising temperature caused by global warming alters physiology, phenology and/or distribution in a wide array of plant and animal species, which has dramatic knock-on effects at different levels of organisation. This study investigates the individual and interactive effects of temperature (18ᵒC, …

Thermal property of EDS film and its effect on the removal of dust particles as a function of surface temperature
… very low energy. However, the high ambient temperature in deserts leads to a decrease of efficiency of the silicon solar panels, and the EDS film has a potential influence on increasing temperature of the panels. This thesis focuses on the thermal property of EDS film and to determine its …

Synthesis and evaluation of polyol based biolubricants from vegetable oils
… oils with excellent oxidative stability and low temperature flow properties. In the first study, a strong positive correlation was observed between saturated fat content and melting point while the content of polyunsaturated fatty acids (PUFA) was negatively correlated with oxidative stability. …

Mechanical characterization of carbon nanosheets
… to a systematic increase of Youngs moduli with rising temperature, up to 48 GPa at ~1000 K. Finally, polymer brushes grafted on biphenyl-based nanosheets provided a new class of material termed as "polymer carpet". Both bulge test and nanoindentation were used to characterize the mechanical …

Geospatial Analysis of the Global Supply Chain and Transportation Infrastructure Considering Extreme Weather, Climate, and Sustainable Energy Policies
… hurricanes, and sea level rise. Earth’s rising temperature plays the most significant role in sea level rise. The next step in this research deals with modeling the Earth’s temperatures through autoregressive integrated moving average (ARIMA) model equations. ARIMA modeling allows for …

Mid-infrared antimonide based type II quantum dot lasers for use in gas sensing
… QD light sources on GaAs. From the study of PL temperature quenching, thermal excitation of holes out of the QDs was identified as one of the major reasons for weaker PL/EL signals at higher temperature range. To compensate the thermal leakage problem, the QDs integrated on InP substrates were …

Rhythms, feeding and respiration of the oyster Crassostrea gigas
… Crassostrea gigas under constant conditions of temperature, light, salinity, water level and food availability. Rhythms continued for up to 6 weeks until the experiments were terminated. The rhythms showed a high degree of temperature compensation between 13 - 24˚C, but at 4˚C the free-running …

Superstructures of Magnetic Materials
… Measurements of SmNiC2 were performed within the temperature range of 8 - 300 K. Refection peaks were analyzed for a possible peak-splitting as a consequence of a lowering of the symmetry of the crystal lattice in the charge-density wave state as well as in the ferromagnetically ordered state. It …
