We subjected III–V InGaAs MOSFETs to positive and negative gate stresses. The stress polarity strongly affects the degradation kinetics of the gate current. Positive stress features a remarkable increase of the gate current, a net negative trapped charge, a large telegraphic noise, and soft breakdown, before the occurrence of the final catastrophic breakdown. Negative stress features only posit...

[1] Midlatitude cirrus cloud radiative forcing (CRF) values at the tropopause over China are estimated using a radiative transfer model initialized by Earth‐orbiting Cloud‐Aerosol Lidar with Orthogonal Polarization (CALIOP) and Moderate Resolution Imaging Spectroradiometer (MODIS) measurements. A derived diurnal mean CRF, solved as a function of solar zenith angle, , though varied over the sola...

for evaluation of drought tolerance of sugar beet genotypes by assessment of the drought tolerance indices under mild and severe stresses, furrow irrigated field experiments were carried out at zarghan research station in 2002 and 2004, and at motahari research station (located inkaraj) in 2002, 2003, and 2004. the experimental design was split plot, with a randomized complete block arrangement...

Graham, J.L. and J.R. Jones. 2007. Microcystin distribution in physical size class separations of natural plankton communities. Lake and Reserv. Manage. 23:161-168. Phytoplankton communities in 30 northern Missouri and Iowa lakes were physically separated into 5 size classes (>100 μm, 53-100 μm, 35-53 μm, 10-35 μm, 1-10 μm) during 15-21 August 2004 to determine the distribution of microcystin (...

The magneto-induced stress and relative microstructure in a colloidal suspension of paramagnetic and superparamagnetic particles dispersed in a ferrofluid medium is studied using particle-level dynamics simulation. It shows that the stress perpendicular to the direction of an external uniaxial magnetic field can be strongly enhanced by increasing the ratio of paramagnetic particles to approachi...

in order to evaluation the effect of drought stress on germination indices and early seedling growth of medicinal herb dill (anethum graveolens l), an experiment was conducted in the agricultural laboratory of urmia payam noor university in 2015 as a randomized complete block design with four replications. treatments were five levels of drought stress (0, -1, -2, -3 and -4 bar induced by polyet...

The presence of salt in the soil profile negatively affects the growth and development of vegetation. As a result, the spectral reflectance of vegetation canopies varies for different salinity levels. This research was conducted to (1) investigate the capability of satellite-based hyperspectral vegetation indices (VIs) for estimating soil salinity in agricultural fields, (2) evaluate the perfor...
