It has been known for some time (Hansen, 1891) that organic esters may be produced in small amounts by some microorganisms as byproducts in their utilization of organic compounds. A detailed review of the literature to 1922 on aroma producing microorganisms is given by Omelianski (1923). The taxonomy of the yeast genus Hansenula, which contains species producing the greatest yields of ester, is...

CHROMagar Candida is a novel, differential culture medium that is claimed to facilitate the isolation and presumptive identification of some clinically important yeast species. We evaluated the use of this medium with 726 yeast isolates, including 82 isolated directly on the medium from clinical material. After 2 days of incubation at 37 degrees C, 285 C. albicans isolates gave distinctive gree...

Keywords: RAD-NETT Radiation heat transfer Neural network Fire resistance test furnace a b s t r a c t Using RAD-NETT, a neural network correlation of the non-gray radiative absorption properties of combustion gases (CO 2 and H 2 O) and soot, the emissivity and hemispherical absorptivity of a combustion mixture to a boundary in a rectangular enclosure is determined. Results show that the both t...

botrytis cinerea is an important pathogen that causes diseases in ornamental crops. in presentresearch several greenhouses of roses located in central region of iran were surveyed toidentify the botrytis cinerea. a total of 80 isolates were collected from rose greenhouses incentral region of iran. morphological identification was based on characters such asconidiophore and conidial length. acco...

Radiative heat transfer in three-dimensional nonhomogeneous participating medium was investigated by using REM 2 method. The anisotropic scattering phase function was dealt with the scaling technique based on delta function approximation. The three-dimensional scaled isotropic results were compared with the published anisotropic scattering computations. A good agreement between the scaled isotr...

Abstrae--The normal-mode-expansion technique is used to obtain a semi-analytical solution for the angular distribution of radiation at any optical distance within a linearly anisotropicscattering, absorbing, emitting, non-isothermal, gray medium between two parallel reflecting boundaries. Both conservative and nonconservative cases are considered. The general problem is decomposed into simpler ...

in this paper, the effects of baffle on thermal characteristics of combined convection-radiation heat transfer in laminar flow adjacent to an inclined backward facing step (bfs) in a horizontal duct are investigated. a baffle is mounted on the top wall of channel downstream side of step. in this study, the fluid is treated as a gray, absorbing, emitting and scattering medium; therefore, in the ...
