A Combinatorial Method for Discovery of BaTiO3-based Positive Temperature Coefficient Resistors [PDF]

open access: yes, 2010
PhDThe conventional materials discovery is a kind of empirical (“trial and error”) science that of handling one sample at a time in the processes of synthesis and characterization.

THE TEMPERATURE COEFFICIENT OF PHOTOSYNTHESIS [PDF]

open access: yesJournal of General Physiology, 1919
The temperature coefficient of photosynthesis in Ulva (between 17° and 27°C.) is 1.81. This may be explained by assuming that the process involves a light reaction with a low coefficient followed by an ordinary reaction with a high coefficient.

Mechanisms of increasing predation by planktivorous fish with rising temperature may explain the temperature–body size relationships in zooplankton

open access: yesFrontiers in Ecology and Evolution, 2023
The temperature–size rule (TSR) has been consistently observed in numerous studies, showing that ectotherms reared at higher temperatures experience accelerated growth during the juvenile stage and ultimately reach smaller sizes and younger ages at ...

Investigation of the Temperature Sensitivity of 20-Years Old Field-Aged Photovoltaic Panels Affected by Potential Induced Degradation

open access: yesEnergies, 2022
One effect of moisture ingress on solar panels is potential induced degradation (PID). Solar panels affected by PID experience large leakage currents between the solar cells and the module’s frame, which leads to substantial power degradation.

Quadratic behavior of fiber Bragg grating temperature coefficients [PDF]

open access: yes, 2004
We describe the characterization of the temperature and strain responses of fiber Bragg grating sensors by use of an interferometric interrogation technique to provide an absolute measurement of the grating wavelength. The fiber Bragg grating temperature

Reliability evaluation of MMC system considering working conditions

open access: yesThe Journal of Engineering, 2018
The reliability is a key issue of the high-voltage high-power modular multilevel converter (MMC) system due to the usage of fragile insulated gate bipolar transistor (IGBT) modules. In this study, it is proposed that the reliability of the MMC system can

Research on the Temperature Characteristics of the Photoacoustic Sensor of Glucose Solution

open access: yesSensors, 2018
In order to weaken the influence of temperature on photoacoustic (PA) measurements and compensate PA signals with a proposed theoretical model, the relationship of PA signal amplitude with temperature, under the condition of different glucose ...

Comparative study of electrical resistance of disc-shaped compacts fabricated using calcined clams shell, Periwinkle shell and Oyster shell nanopowder [PDF]

open access: yesKragujevac Journal of Science, 2022
In this investigation, Clam, Periwinkle and Oyster shells were separately treated, calcined and ball-milled into nano powder. Each nano powder material was fabricated into disc of various lengths in three replicates.

Consideration of the temperature factor of atmospheric air when determining standard consumption of fuel and energy resources for train traction

open access: yesВестник Научно-исследовательского института железнодорожного транспорта, 2018
. Influence of air temperature on the consumption of fuel and energy resources (FER) on train traction is due to a number of physical laws. The extent of this effect is specified in the Rules for Traction Settlement (RTS).

THE TEMPERATURE COEFFICIENT OF PHAGOCYTOSIS [PDF]

open access: yesJournal of General Physiology, 1922
1. The experiments of Madsen and Watabiki on the effect of temperature on the phagocytosis of bacteria are discussed and a new analysis of their curves is given, showing that the rate of phagocytosis is very nearly a logarithmic function of the temperature from 0° to 35°C.; i.e., Q10 is constant over that range and is equal to 2.0.
