We report on the detection of four primordial galaxies candidates in the redshift range 4.55 ≤ z ≤ 4.76, as well as 4 other candidates in the range 4.12 ≤ z ≤ 4.32. These galaxies have been detected with the now common technique of the Lyman break, but with a very original instrumental setup, which allows the simultaneous detection on a single exposure of three narrow (FWHM ∼ 200 Å) bands. Depe...

Purpose: Probiotics are microorganisms, which show beneficial health effects on hosts once consumed in sufficient amounts. Among probiotic bacteria, the bioactive compounds from lactic acid bacteria (LAB) group can be utilized as preservative agents. LAB group can be isolated and characterized from traditional dairy sources. This study aimed to isolate, identify, and biologically characterize p...

We clarified the controlling factors of particle size amorphous silica synthesized by wet and dry processes. In process using methyl-trimethoxy-silane as a starting monomer, obtained can be easily controlled changing reaction time appropriately. However, to obtain larger particles, relatively long is needed. After condensation was conducted for 50h, particles (D50: 3?m) were calcination at 550o...

BACKGROUND Cardiogenic dysfunction with acute renal failure (ARF) and diuretic drug resistance increases mortality after cardiac surgery with cardiopulmonary bypass (CPB) in adults. Until few years ago, intermittent renal replacement therapy (IRRT) was the only therapeutical strategy proposed to such patients. Few data are available in the literature regarding the use of continuous veno-venous ...

ABSTRACT In experiments conducted in growth chambers with the susceptible wheat cultivar BR 23, interactions between five temperatures (10, 15, 20, 25 and 30°C) eleven wetting periods were assessed for fusarium head blight (FHB) intensity. Each temperature consisted of one experiment hours corresponded to treatments. The disease occurred even at 10ºC, minimum tested temperature, maximum inciden...

Very high gravity (VHG) technology was employed on industrial scale to produce ethanol from molasses (fermented) as well as by-products formation estimation. The effect of different Brix° (32, 36 and 40) air-flow rates (0.00, 0.20, 0.40, and 0.60vvm) was studied on ethanol production. The maximum ethanol production was recorded to be 12.2% (v/v) at 40 Brix° with 0.2vvm air-flow rate. At optimum...

Rat liver mitochondria were found to hydroxylate E-Ntrimethyl+lysine to produce P-hydroxy-c-N-trimethyl-L-lysine, an intermediate in carnitine biosynthesis. The hydroxylating system requires a-ketoglutarate, Fez+, and ascorbate, but does not require NADPH nor NADH. No activity was found in the microsomal or soluble fractions of liver extracts. The hydroxylated a-amino acid was isolated and char...

We use cosmological magneto-hydrodynamic simulations to study the evolution of magnetic fields in galaxy clusters in two different cosmological models, a standard-CDM and a Λ-CDM model. We show that the magnetic field strength profiles closely follow the cluster density profiles outside a core region of radius ∼ 200h kpc. The magnetic field has a correlation length of order 50h kpc and reverses...

in this research, the high-energy planetary mill was employed to produce nanocrystalline ti-50al(γ)(at%) powders. initial powders were mechanically alloyed in 99.9999% and 90% purities of argon and also air atmosphere with alloying times up to 50h. the effect of impurity of argon atmosphere on the microstructure and the rate of phase transformation of ti-50al were investigated during mechanical...

Certain monoclonal antibodies (MoAbs) specific for platelet membrane glycoproteins are known to be capable of activating platelets, and it is generally thought that platelets from normal subjects are equally susceptible to stimulation by such MoAbs. We found that platelets from 20 normal donors varied significantly in their sensitivity to three IgG1 murine MoAbs specific for membrane glycoprote...
