A further characterization of Actinomyces tumemacerans Krassilnikov and Koveshnikov, 1962 strain INMI P-42 was carried out. It is classified in Section Monoverticillus-Spira, Series white to gray. When the organism was shakecultured in a wheat flour medium, an antibacterial antibiotic with limited antitumor activity was isolated from the culture filtrate and a tetraene antibiotic from the mycel...

We investigate the propagation of a dark beam in a defocusing medium in the strong nonlinear regime. We observe for the first time a shock fan filled with noninteracting one-dimensional gray solitons that emanates from a gradient catastrophe developing around a null of the optical intensity. This scenario turns out to be very robust, persisting also when the material nonlocal response averages ...

Analytical solutions of an unsteady magnetohydrodynamic (MHD) flow with heat and mass transfer characteristics incompressible, viscous, electrically conducting, Boussinesq fluid over a vertical oscillating plate embedded in Darcian porous medium the presence thermal radiation are presented. The considered here is gray, absorbing/emitting radiating, but nonscattering medium. At time t > 0, tempe...

The present study aimed at evaluating the cytotoxic effects of a novel cement called CER on periodontal fibroblast-like cells of mice (MDPL-20), in comparison with different formulations of Mineral Trioxide Aggregate (MTA), by means of the cell viability test (MTT) and cell morphology analysis. Thirty-two round-shaped samples were fabricated with the following cements: white MTA, white and gray...

Gray and Loh (1) have shown previously that dietary ƒ¿-tocopheryl acetate (ƒ¿ TAc) brings about increases in phospholipids, total and free cholesterol in the plasma of healthy human subjects. It seemed probable that the dietary ƒ¿TAc affected the liver cell itself, the blood being merely a transport medium. This hypothesis was investigated, using rat liver homogenates from animals main tained f...

Temporal Digital Subtraction Angiography (DSA) is used to visualize blood vessels in x-ray images. A DSA image pair consists of the mask image, which is a digitized x-ray taken before a contrast medium is injected into the bloodstream, and the live image, which is taken once the contrast medium has traversed the circulatory system and reached the blood vessels of interest. The mask image is the...

In this study an expression for soot absorption coefficient is introduced to extend the weighted-sum-of-gray gases data to the furnace medium containing gas-soot mixture in a utility boiler 150 MWe. Heat transfer and temperature distribution of walls and within the furnace space are predicted by zone method technique. Analyses have been done considering both cases of presence and absence of soo...

A double-pulsed gradient spin echo (d-PGSE) filtered MRI sequence is proposed to detect microscopic diffusion anisotropy in heterogeneous specimen. The technique was developed, in particular, to characterize local microscopic anisotropy in specimens that are macroscopically isotropic, such as gray matter. In such samples, diffusion tensor MRI (DTI) produces an isotropic or nearly isotropic diff...

Generally, the long-medium power load forecasting sequence has small sample, stochastic growth and nonlinear wave characteristics. Gray and SVM model could reflect the relationship between growing characters-tics and nonlinear characteristics to the series effectively and make fitting calculation. The paper modifies the proposed gray model through posterior-error-test and compares the predictiv...

asmari formation was deposited in the foreland zagros basin (southwest iran). in this research, biostratigraphy related to the asmari formation in north of khorram abad, robat namaki section, is discussed. in the studied stratigraphic section, the asmari formation overlies the shahbazan formation and underlies gachsaran formation and consists of cream to gray medium to thick limestone and marl....
