abstract: large quantities of beef and mutton tallow are available in iran every year. if these products are processed and formulated properly and scientifically, the need to import oils and fats in a substantial quantities might be reduced. the aim of this study is to fractionate beef tallow into different fractions and carry out physical and chemical tests on each isolated fraction. beef fat ...

Datura metel stramonium (leaves) extract has traditionally been used to treat swellings, burns, ulcers, asthma and sinus infections. However, report indicate that this plant is a strong poison linked delirium acute poisoning, which may result in death. Aim: Histomorphological potentials biochemical effects of on the kidneys adult male Wistar rats. Fresh leaves were harvested, cleaned, air-dried...

The biochemical properties of a purified enzyme of a new alkalophillic endo-1,4-beta-xylanase gene, KRICT PX2 (GU967374), which was isolated from Paenibacillus sp. HPL-002 (KCTC11410BP) and expressed in E. coli, were investigated. The specific activity of the purified xylanase was 51.26 μmol/min/mg proteins. The Km and Vmax values of the protein for birch wood xylan were also verified to have 0...

The extremely halophilic archaeon Natrinema sp. strain SSBJUP-1, which produces extracellular cellulase and xylanase, was isolated from the Lonar Lake situated in Buldhana, Maharashtra. The enzymes were optimally active at pH 9–10 and temperature 40–60 C and they were most stable up to pH 11 and 16 % of NaCl concentration. The xylanase showed maximum activity at 50C and cellulase at 40C. Xylana...

A Stability indicating reverse phase high performance liquid chromatographic method has been developed for the simultaneous determination of Levocetirizine dihydrochloride and Pseudoephedrine sulfate in pharmaceutical formulation. The mobile phase A consisted of Potassium dihydrogen phosphate Buffer 0.05M and 1-Ocatne sulphonic acid sodium salt 0.25%, pH adjusted to 3.0 with orthophospheric aci...

Poverty, drug resistance and other factors including increasing difficulty in the control of mosquitoes (the vector of the causative organism of malaria), have led to a growing interest in phytochemical research. The antioxidant activity of Newbouldia laevis stem bark was investigated. Air dried stem bark of N. laevis was powdered and extracted with 95 % v/v methanol by maceration, and the extr...

This paper presents an analysis of the impact of the Development Assurance Level (DAL) or Safety Integrity Level (SIL) on the system activities in various application domains represented in the CG2E “Club des Grandes Entreprises en Embarqué”) and specially on the dependability, safety norms and standards working group. The main goals of this paper are to: • Analyse the impact in each applicatio...

The welding heat input has a great influence on the weldments properties. This paper describes the influence of welding heat input on the weld metal toughness of high-carbon steel surface welded joint. The steel is surfaced with self-shielded wire, with three different heat inputs (6.5; 10.5 and 16 kJ/cm). Total impact energy, as well as crack initiation and crack propagation energies, are esti...

Patulin is a common contaminant in fruits and vegetables, which is difficult to remove. In this study, the biodegradation of patulin using porcine pancreatic lipase (PPL) was investigated. The method of HPLC was used to analyze the concentration of patulin. Batch degradation experiments were performed to illustrate the effect of PPL amount, pH, temperature, contact time, and initial concentrati...
