gelled propellants are improved propellants that can be considered as the final extension of liquid propellants. high specific impulse, good density and safety better than that of both solid and liquid propellants are advantages of the gel propellants. they are made by addition a suitable gellant to liquid propellants. in this research, nano al particles have been used in udmh gel fuel. the gel...

This study was conducted to compare different liquid culture media for Paenibacillus larvae growth in order to find the best one to be used in studies on activity of antimicrobial substances, such as essential oils. P. larvae presented poor growth in usual broths such as Mueller-Hinton, commonly employed in antimicrobial activity assays. Growth in liquid media was evaluated using Paenibacillus ...

The crater formation due to the impact of a water droplet onto a granular bed has been experimentally investigated. Three parameters were tuned: the impact velocity, the size of the droplet, and the size of the grains. The aim is to determine the influence of the kinetic energy on the droplet pattern. The shape of the crater depends on the kinetic energy at the moment the droplet starts to impa...

The present investigation was aimed at studying the effect of incubation period, media, vitamins and solvents on biotransformation of albendazole by Cunninghamella blakesleeana. The transformation was evaluated and identified by high performance liquid chromatography (HPLC) and the structures of the transformed products were assigned by liquid chromatography-tandem mass spectrometry (LC/MS/MS) ...

1. Certain water-soluble esters of long chain fatty acids (in particular of oleic acid) favor submerged and diffuse growth of mycobacteria throughout the depth of synthetic liquid media. 2. Esters of oleic acid increase considerably the amount of growth yielded by avian strains in synthetic media. 3. The addition of serum albumin to synthetic liquid media permits visible growth of minimal inocu...

different compositions of liquid media were used for their efficacy in the production of beta-galactosidase by aspergillus oryzae in submerged fermentation. enzyme production was improved by switching from lactose-based media to soybean meal- and wheat bran-based media. further improvement was made when the soybean meal medium was supplemented with sodium nitrate and magnesium sulfate. results ...

Fischer, 0.: Enhancement of Propagation of Mycoplasma hyopneumoniae by Culture in a Biphasic Medium. Acta vet. Bmo, 1995,64:243-247. Mycoplasma hyopneumoniae (strain J) was propagated in a liquid and a biphasic media. The solid phase of the biphasic medium was obtained by the addition of 1.9% or 0.19% of agar to the liquid medium. Compared with the liquid medium, a more rapid propagation of myc...

[1] The lattice Boltzmann method (LBM) has emerged as a powerful tool for simulating the behavior of multiphase fluid systems in complex pore networks. Specifically, the single component multiphase LBM can simulate the interfacial phenomena of surface tension and adsorption and thus be used for modeling fluids such as water and its vapor in porous media. This paper provides an introduction to L...

BACKGROUND Tuberculosis Trials Consortium Study 28, was a double blind, randomized, placebo-controlled, phase 2 clinical trial examining smear positive pulmonary Mycobacterium tuberculosis. Over the course of intensive phase therapy, patients from African sites had substantially delayed and lower rates of culture conversion to negative in liquid media compared to non-African patients. We explor...

The theoretical framework for dissolution of weak acid and weak base drug compounds in buffered media is well established. Therefore, this article is intended to provide a review of this framework and apply it to formulate buffered dissolution media based on ionic equilibrium conditions within the diffusion layer at the solid–liquid interface. The pHo in the microenvironment is identified as a ...
