Protein balance in rat muscles incubated in vitro is influenced by the supply of insulin, leucine and various hormones at physiological concentrations (0.1-0.5 mM) (Goldberg & Chang, 1978; Goldberg et al., 1980). Leucine, but no other amino acid, stimulates protein synthesis and inhibits protein breakdown in this tissue. Metabolism of leucine is necessary for its inhibitory effect on proteolysi...

GaN FETs offer superior advantages in high-voltage and high-temperature operation due to its large bandgap (3.4 eV) and high breakdown field strength (3.3 MV/cm). This combination of the large bandgap and high breakdown field makes these devices very attractive for power switching applications. In this regard, a key figure of merit is the breakdown voltage of the transistor, which must be high ...

Breakdown strength is an important electrical property of insulating paper. Oil-impregnated paper of various aging states was prepared. Its breakdown voltage was then measured at pulsating direct current (DC) voltage with various ripple factors, and alternating current (AC) and DC voltage for comparison, respectively. The AC breakdown voltage is the smallest, and pulsating DC (r = 1/5) breakdow...

A bstruct-Electrical breakdown, both intrinsic and extrinsic, of thin film diodes used as switches in active matrix addressed liquid crystal displays has been studied using eIectrical measurements, thermal measurements, thermal 3D simulations, electrical simulations and post breakdown observations. The diodes used in this study consist of a layer of 30 nm amorphous hydrogenated silicon rich sil...

Time-dependent dielectric breakdown (TDDB) characteristics of La2O3-doped high-k dielectric in Hf-based high-k/TaN metal gate stack were studied. Unlike the abrupt breakdown in the conventional SiO2, dielectric breakdown behaviors of La-incorporated HfON and HfSiON dielectrics show progressive breakdown characteristics. Moreover, the extracted Weibull slope β of breakdown distribution is in the...

objectives: it was aimed to investigate the effects of different doses of follicle stimulating hormone (fsh) and activin a on the growth and maturation of preantral mouse follicles during the in vitro culture. methods: preantral follicles (90-100 µm in diameter) were harvested from 6-8 week-old syrian mice and cultured in tcm199 culture medium for 6 days to see the effect of fsh and activin a. ...

This paper addresses the problem of dielectric breakdown in composite materials. The dielectric breakdown model was generalized to describe dielectric breakdown patterns in conductor-loaded composites. Conducting particles are distributed at random in the insulating matrix, and the dielectric breakdown propagates according to new rules to take into account electrical properties and particle siz...
