Environmental temperature is an important factor exerting pervasive influence on neuronal morphology and synaptic physiology. In the Drosophila brain, axonal arborization of mushroom body Kenyon cells was enhanced when flies were raised at high temperature (30 degrees C rather than 22 degrees C) for several days. Isolated embryonic neurons in culture that lacked cell-cell contacts also displaye...

BACKGROUND Bioprocesses depend on a number of different operating parameters and temperature is one of the most important ones. Unfortunately, systems for rapid determination of temperature dependent reaction kinetics are rare. Obviously, there is a need for a high-throughput screening procedure of temperature dependent process behavior. Even though, well equipped micro-bioreactors are a promis...

Thermoelastic behavior of temperature-dependent (TD) and independent (TID) functionally graded variable thickness cantilever beam subjected to mechanical and thermal loadings is studied based on shear deformation theory using a semi-analytical method. Loading is composed of a transverse distributed force, a longitudinal distributed temperature field due to steady-state heat conduction from root...

A study was conducted to determine the effects of water temperature and rations size on growth performance, feed utilization and carcass biochemical composition of juvenile Benni. Six treatments representing a combination of two water temperature (24 and 28 °C) and three feeding rations (1%, 3% and 5%) were tested with three replicates. Each replicate was stocked with 12 fish (30.66±0.81 g aver...

Experiments were carried out in which the dependence of the fractional softening on temperature, time and strain rate was determined in a 304H stainless steel. Three prestrain ranges were identified pertaining to three different post-deformation softening behaviors: 1) prestraining to below the DRX critical strain: strongly strain dependent softening by SRX alone with softening kinetics control...

At high ambient temperature, plants display dramatic stem elongation in an adaptive response to heat. This response is mediated by elevated levels of the phytohormone auxin and requires auxin biosynthesis, signaling, and transport pathways. The mechanisms by which higher temperature results in greater auxin accumulation are unknown, however. A basic helix-loop-helix transcription factor, PHYTOC...

Abstract We investigated the growth mechanism of 2D Mo2C crystals by chemical vapor deposition (CVD) under various time and temperature conditions. The kinetics on Cu via were using a modified Johnson-Mehl-Avrami-Kolmogorov (JMAK) model. To analyze surface coverage, we employed scanning electron microscopy (SEM) applied model to determine rate activation energy. exhibited temperature-dependent ...

Temperature-dependent growth is an important factor in the population model of Corophium volutator that was developed to translate responses in a 10-day acute bioassay to ecological consequences for the population. The growth rate, however, was estimated from old data, based on a Swedish population. Therefore, new growth rates are estimated herein from two experiments using Corophium volutator....

A plan-view TEM study has been made of the distribution, geometry and the time-dependent annealing behavior of type II (end of range) dislocation loops introduced by 1 x 10’5/cm2 50 keV Si+ implantation into silicon. The size and density distributions of the loops have been quantitatively analyzed, and loop growth behavior has been compared with that predicted by a bulk-diffusion mechanism and ...

polyhydroxyalkanoates (phas) are bioplastics derived from renewable resources such as vegetable oils, corn starch, or microbes. the polyhydroxybutyrate (phb) is a short-chain-length pha, and the most important bioplastic produced by certain microorganisms in the presence of excess carbon sources. in this study batch cultivation of alcaligenes eutrophus with the aim of increasing phb production ...
