Kinetic modeling of detonation and effects of negative temperature coefficient [PDF]

, 2016
The kinetic modeling and simulation of reactive flows, especially for those with detonation, are further investigated. From the theoretical side, a new set of hydrodynamic equations are deduced, where the viscous stress tensor and heat flux are replaced ...

Low-Power MOSFET-Only Subthreshold Voltage Reference with High PSRR [PDF]

AUT Journal of Electrical Engineering
This work presents a sub-nanowatt voltage reference (VR) achieving a high-power supply ripple rejection (PSRR). It utilizes a self-current biasing circuit to reduce the voltage dependency of the output voltage (VREF) to the power supply variations.

THE TEMPERATURE COEFFICIENT OF RADIOACTIVE DISINTEGRATION [PDF]

Proceedings of the National Academy of Sciences, 1929
One of the most remarkable features of radioactive changes is the fact that they have extremely low-temperature coefficients, it being impossible to influence the half-life of a radioactive substance by changing the temperature over any range at our command.

Composite resistor standard for calibration of measuring transducers in laboratory conditions [PDF]

Serbian Journal of Electrical Engineering, 2016
Calibration of measuring transducers for precision measurement is done by measuring voltage drop at the resistor standard, produced by output dc current proportional to the input measured value.

Secretory Phospholipase A2 in Patients With Sickle Cell Disease Hospitalized for Vaso‐Occlusive Pain Episodes

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Secretory phospholipase A2 (sPLA2) is an inflammatory mediator linked to acute chest syndrome (ACS) in sickle cell disease (SCD), a serious complication that can develop during an acute vaso‐occlusive pain episode (VOE). Plasma sPLA2 levels have been proposed as a potential biomarker for predicting ACS onset.

Temperature coefficients of quartz at cryogenic temperature [PDF]

2017 Joint Conference of the European Frequency and Time Forum and IEEE International Frequency Control Symposium (EFTF/IFC), 2017
The temperature coefficients of the elastic coefficients of quartz within [4 K, 15 K], the operating range of conventional cryocoolers, are predicted from experimental data. Raw data consist of a set of frequency-temperature curves recorded from bulk acoustic wave resonators made in different plates cut according to various angles relative to the ...
