We report on 27 patients illustrating the use of non-vascularized single fibular strut graft, augmented with a corticocancellous bone graft to bridge bone defects. The indications were varied and included infection, fracture with bone loss, non-union, bone tumour, bone cyst and congenital pseudarthrosis. Primary union was achieved in 92 per cent. Stress(More)
A previously developed mathematical model for ethylene polymerization in a fluidized bed reactor was used to investigate the process static and dynamic behavior. The static analysis determined optimal operating conditions at which the monomer conversion can be increased to 25% per pass. However, this optimal operating point was shown to be unstable and thus(More)
This research focused on combined organic-inorganic fouling and cleaning studies of forward osmosis (FO) membranes. Various organic/inorganic model foulants such as sodium alginate, bovine serum albumin (BSA) and silica nanoparticles were applied to polyamide-polyethersulfone FO hollow fiber membranes fabricated in our laboratory. In order to understand all(More)
Large amounts of low-quality dates produced worldwide are wasted. Here, highly concentrated fructose syrups were produced via selective fermentation of date extracts with Saccharomyces cerevisiae. Syrups with 95.4–99.9 % (w/w) fructose yields were obtained from date extracts having an initial sugar range of 49–374 g/l without media supplementation; the(More)
Thirty-one patients with suspected radiolucent foreign bodies (wooden splinters) in soft tissues of extremities were investigated by plain radiography, computed tomography (CT) scan and ultrasonography to the area suspected clinically. Ultrasonography detected and localized radiolucent foreign bodies in 18 of the 31 patients, while only 14 were seen on CT(More)
An industrial grade acidic crude palm oil (ACPO) pre-treatment process was carried out using ethanesulfonic acid (ESA) as a catalyst in the esterification reaction. ESA was used in different dosages to reduce free fatty acid (FFA) to a minimum level for the second stage of biodiesel production via alkaline transesterification reaction. Different process(More)
Modulation of crystallization of stearic acid and its derivatives is important for tuning the properties of stearate oleogels. The present study delineates the crystallization of stearic acid in stearate oleogels in the presence of Span 60. Microarchitecture analysis revealed that stearic acid crystals in the oleogels changed its shape from plate-like(More)
BACKGROUND High Density Polyethylene (HDPE) is one of the most often used polymers in biomedical applications. The limitations of HDPE are its visco-elastic behavior, low modulus and poor bioactivity. To improve HDPE properties, HA nanoparticles can be added to form polymer composite that can be used as alternatives to metals for bone substitutes and(More)
Direct alcohol fuel cells have been attracting enormous research interest as power sources for vehicles and portable electronic devices because alcohols are readily available, their storage and transport can be easily handled with the existing fuel infrastructure, and they commonly have high mass-specific and volumetric energy densities. Methanol is the(More)
