Navier-Stokes simulations of three-dimensional flow and augmented convection in a channel with symmetric, transverse grooves on two opposite walls were performed for 180 <Re<1600 using the spectral element technique. A series of flow transitions was observed as the Reynolds number was increased, from steady two-dimensional flow, to traveling two and three-dimensional wave structures, and finall...

Yttrium silicate coating[5, 6] is a promising candidate for oxidation resistant coating for its low oxygen diffusion coefficient and similar thermal expansion coefficient with silicon carbide. Webster et. al.[7] had prepared yttrium silicate coating on C/SiC using Y2O3/SiO2 slips by slip casting and sintering. The selected sintering parameters were 3 h at 1600 °C in flowing argon. The coating c...

The existence of circadian cycles of plasma lactic dehydrogenase has been confirmed. This cycle is characterized by having its lowest activity at 0800 hours and its highest activity between 1600-2000 hours. A diurnal variation in urinary excretion of lactic .dehydrogenase has been described which features an inverse relationship to that of the plasma in that maximum excretion occurs during the ...

Artikulu honetan, Lakarrak (1997) eta ondoren Gorrochateguik (2001) euskararentzat egindako periodizazio saioak goi-nafarrerarentzat balio duen ikusten saiatu naiz dialekto horren proposamen bat egiten dut. Batez ere, goi-nafarrera arkaikoa (1416-1600) zaharra (1600-1745) definitzeko balia litezkeen ezaugarri linguistikoez arituko naiz. Dialektoaren garaikatze hori egiteko hizkuntzaren barneko ...

We demonstrate efficient generation of highly nondegenerate photon pairs with a type-I phase-matched, periodically-poled lithium niobate parametric downconverter. The signal photons at 800 nm and the idler photons at 1600 nm were generated in a collinear-propagation configuration with an inferred pair generation rate of 1.4×107/s/mW of pump power. Detection of a signal photon triggered a thermo...

Yemlik kolza için ideal ekim normunun belirlenmesi amacıyla bu çalışma yürütülmüştür. Çalışmada dekara 400 g, 800 1200 1600 2000 g ve 2400 olmak üzere altı normu kullanılmıştır. Ekimler 02 Ekim 2020 tarihinde, hasatlar ise 29 Nisan 2021 tarihinde yapılmıştır. farklı normlarının bitki boyu, yeşil ot verimi, kuru ham protein, ADF, NDF sindirilebilir madde oranları, nispi yem değeri, kalsiyum, mag...

Chronic treatment with Delphinium denudatum (Dd) (Jadwar) (family: Ranunculaceae, 200-1600 mg/kg) suppressed morphine withdrawal jumps in a dose-dependent manner, a sign of the development of dependence to opiate as assessed by naloxone (2 mg/kg) precipitation withdrawal on day 10 of testing in mice. Repeated administration of Dd (200-1600 mg/kg) for 9 days attenuated the development of toleran...
