BACKGROUND The amino acid derivative 3,4-dihydroxy L-phenylalanine (L-dopa) is gaining interest as a drug of choice for Parkinson's disease. Aspergillus oryzae is commonly used for L-dopa production; however, a slower growth rate and relatively lower tyrosinase activity of mycelia have led to an increasing interest in exploiting alternative fungal cultures. In the present investigation, we repo...

In this work we study the process of co-combustion pulverized coal fuel (coal grinded up to 100 microns) and liquid (diesel) in a new low-power burner, where coal-air mixture is fed tangentially together with secondary air, atomized by high-velocity steam jet. Temperature profiles composition intermediate combustion products along vertical axis burner have been studied. The heat release (power)...

Mechanical properties of copper (Cu) film under grinding process were accomplished by molecular dynamics simulation. A numerical calculation was carried out to understand the distributions of atomic and slip vector inside the Cu films. In this study, the roller rotation velocity, temperature, and roller rotation direction change are investigated to clarify their effect on the deformation mechan...

Background: Diamond burs are recommended for grinding enamel and they are available in different grid sizes, therefore the aim of this study was to evaluate the effect of beveling with 4 different grid size diamond fissure bur s on shear bond strength of light cured composite resin. Materials and Methods: Forty extracted anterior teeth were sectioned at the level of cervical line. The crowns we...

Utilisation of palm oil mill wastes to make soil conditioner through anaerobic co-composting is feasible and has the potential to maintain the natural resources, and to reduce the impact on environmental quality in the future. Co-composting process uses pressed-shredded-grinded empty fruit bunch (EFB) with activated sludge (AS) from the pond system of a palm oil mill as a suitable option for or...

Rice is predominantly a starch richendosperm portionof paddy (Oryza sativa). It is an important cereal used as staple food by over half of the world population. About 90% of dry matter of milled rice is starch and the rest are non-starch components like protein, lipids and ash. Most of the rice based products in Indian sub continent especially in southern part of India are made from rice flour ...

Corrosion behavior of Ni20Cr coatings deposited by HVOF (high velocity oxygen-fuel) process was evaluated in ZnCl2-KCl (1 : 1 mole ratio) molten salts. Electrochemical techniques employed were potentiodynamic polarization curves, open circuit potential, and linear polarization resistance (LPR) measurements. Experimental conditions included static air and temperatures of 350, 400, and 450°C. 304...

Implementation of landscape approaches to conservation biological control programs requires the confirmation putative sources that contribute predator colonization crops. This study aims confirm dispersal from an alfalfa field a neighboring peach orchard with DNA mark-capture procedure based on topical application solution grinded brine shrimp cysts, Artemia spp. (Anostraca: Artemiidae), follow...

This research work focused on the production of biofuel from orange peels using Bacillus subtilis as a fermentor. The were collected Ekeukwu market and Ihiagwa fruit center, Owerri Nigeria, sun dried grinded manually to powder. sample was further fermented for 8days subtilis, after which it distilled 6 hours in order extract biofuel.Analysis ethanol compostion carried out gas chromatography.The...
