This paper focuses on the melting of phase change material capsulated in elliptical cross-section horizontal cylinder under convective boundary conditions. Different parameters are discussed, namely, HTF inlet temperature and velocity axes ratio capsule cross-section. The effect temperature, velocity, was studied using CFD software FLUENT 6.3.26. A comparison between numerical experimental resu...

Pipelines carrying fluids and slurries are quite common. The third-generation pipelines carrying spherical or cylindrical capsules (hollow containers) filled with minerals or other materials including hazardous liquids are rather a new concept. These pipelines need to be designed optimally for commercial viability. An optimal design of such a pipeline results in minimum pressure drop in the pip...

the intraeconomic specifications of the concept. The present effort attempts to modify the concept by concentrating upon the interface between economic and social conditions. It assumes that competition is not self-sustaining; hence, its very existence, as well as the scope of transactions organized by it, depends upon contextual factors, the "capsule," within which competition takes place. Bot...

OBJECTIVES   We describe our technique and experience with subcapsular placement of the Interstim (Medtronic, Minneapolis, MN, USA) pulse generator in cases of revision for implant site pain. METHODS   The pulse generator and electrode are carefully exteriorized and the floor of the capsule is incised. The system is placed beneath the floor of the original capsule, which then becomes the roof...

Cryptococcosis caused by encapsulated yeast Cryptococcus neoformans most commonly presents as disease of the central nervous system. Cryptococcus is a non-mycelial budding yeast found in soil, pigeon droppings and their nesting places. The three 'classic' virulence factors of cryptococci are: polysaccharide capsule, melanin production and growth at 37°C. Here, we present a rare case of cryptoco...

A simple, accurate, and precise HPTLC method has been developed and validated for the estimation of efavirenz from bulk drug and capsule formulations. The separation was achieved on TLC plates using an appropriate solvent system. The spots so developed were densometrically scanned at 247 nm. The linearity of the method was found to be within the concentration range of 1-40 μg/ml. The validation...

The hard-shell capsule is a commonly used dosage form, and it has been estimated that approximately 60 billion capsule shells are used annually for pharmaceutical products (Podczeck, 2004). The product essentially consists of a hard shell, usually gelatin based, that is almost always filled with a particulate solid. Among the advantages claimed for the hard-shell capsule compared with tablets a...

quinazolinones are heterocyclic and water insoluble compounds with various pharmacological and biological characteristics (antibacterial, antiswelling, antifungal, parkinson and etc.). they are used for treatment hiv and cancer. this study investigated the effects of 4(3h) quinazlonones-2-ethyl-2-phenyl ethyl (qepe) as a new quinazolinons compounds on the spleen and immunocompetent cells of new...
