Mild steel is used as main raw material in fabrication of equipment, chief material of construction and as weapons. During the storage and transportation conditions, it comes in contact with aggressive environment which leads to decrease in mechanical strength. Four different vapor phase corrosion inhibitors (VPCIs) i.e. n-Caprylic acid (CA), nButyric acid (BA), N,N-dimethyl propylene urea (DMP...

The physicochemical properties and fatty acid composition of Attalea dubia (Mart.) Burret (indaiá) seed oil were investigated. The oil was extracted in a soxhlet apparatus using petroleum ether and evaluated for iodine, acid, peroxide, ester, and saponification values. The oil was also analyzed using infrared and nuclear magnetic resonance spectroscopy. The fatty acid profile of the oil was de...

The liposomal delivery of recombinant human tumor necrosis factor (rHuTNF) has been shown to be effective in reducing its toxic effects and in its targeting of organs rich in cells of the reticuloendothelial system. However, native recombinant human TNF shows only poor affinity for liposomes, presumably due to its low hydrophobicity. In an attempt to increase the efficiency of association with ...

OBJECTIVES To prepare and evaluate the protective efficacy of immunoglobulin Y (IgY) prepared against local Saudi Cerastes cerastes snake venom. METHODS The study was conducted between October 2009 and October 2011 at the Center of Excellence in Biotechnology Research, King Saud University, Riyadh, Kingdom of Saudi Arabia.

The paper reports data from four experiments (EXP). Broiler cockerels Ross 308 were allocated to 3 or 5 (EXP 4) dietary treatments comprising 300 (3 replicated pens of 100 chicks per pen), 50, 50 or 100 chickens. The EXP lasted 42, 38, 42 and 38 days. All basal diets contained adequate ingredients. The inclusion of 0.5% caprylic acid (CA) in diets reduced (P < 0.05) body weight (EXP 1). The res...
