different levels of grape pomace extract (ge) were evaluated for their effect on in vitro gas production and as well on some such ruminal fermentation parameters as apparent degraded substrate, volatile fatty acids (vfa), and microbial protein production, in sheep, as ruminal inoculum donor. as for extraction, dried grape pomace and distilled water were mixed in an equal weight ratio. ge was ad...

We analyze the proton electromagnetic form factor ratio R(Q) = QF2(Q 2)/F1(Q ) as a function of momentum transfer Q within perturbative QCD. We find that the prediction for R(Q) at large momentum transfer Q depends on the exclusive quark wave functions, which are unknown. For a wide range of wave functions we find that QF2/F1 ∼ const at large momentum transfer, in agreement with recent JLAB dat...

We present a comparison of high Q-factor tapered membrane-type onedimensional photonic crystal micro-cavities embedded in photonic wire waveguides based on silicon-on-insulator (SOI). Q-factor values as large as 24,000 have been measured, together with normalized transmission of 67%: an improvement in the Q-factor value in comparison with previous results obtained on structures with silicon cor...

In this paper, we present an accelerating cosmological model by constraining the free parameters using datasets in extended symmetric teleparallel gravity for flat and anisotropic space-time. We employ a time variable deceleration parameter that behaves early late acceleration form of Hybrid Scale Factor (HSF). obtain values analyse behavior Universe based on best-fit parameters. derive dynamic...

The optimal spectral efficiency and number of independent channels for MIMO antennas in isotropic multipath are investigated when bandwidth requirements placed on the antenna. By posing problem as a convex optimization restricted by port Q-factor semi-analytical expression is formed its solution. simulated method moments solution formulated both structures fed discrete ports, well design region...

(V1A-TGInd), left ventricular dysfunction and dilatation were also seen, albeit at a later time point. Because the V1A receptor mediates cell signaling through G q protein, we blocked G q signaling by crossing tetracycline-transactivating factor/V1A mice with transgenic mice that expressed a small inhibitory peptide against G q. G q blockade abrogated the development of the heart failure phenot...

We compare the quality factor values of the whispering gallery modes of microdisks (μ-disks) incorporating GaN quantum dots (QDs) grown on AlN and AlGaN barriers by performing room temperature photoluminescence (PL) spectroscopy. The PL measurements show a large number of high Q factor resonant modes on the whole spectrum, which allows us to identify the different radial mode families and to co...

We introduce recent advances in dynamic control over the Q factor of a photonic crystal nanocavity system. By carefully timing a rapid increase of the Q factor from 3800 to 22,000, we succeed in capturing a 4ps signal pulse within the nanocavity with a photon lifetime of 18ps. By performing an additional transition of the Q factor within the photon lifetime, the held light is once again ejected...
