A low cost absorption spectrophotometer for the short wave near infrared spectral region (850-1050 nm) is described. The spectrophotometer is basically composed of a conventional dichroic lamp, a long-pass filter, a sample cell and a Czerny-Turner type polychromator coupled to a 1024 pixel non-cooled photodiode array. A preliminary evaluation of the spectrophotometer showed good repeatability o...

Physicochemical properties of the commercially procured rubber seed oil (RSO) were studied to evaluate its potential as viable feedstock for biodiesel production. The procured rubber seed oil were characterized for acid value, saponification value, free fatty acid, flash point, kinematic viscosity, and refractive indices using standard methods. Results indicate that the procured rubber seed oil...

The potential of three molecules NH 4 NO 2 , H O and 3 to ignite aqueous solutions ammonia (25% by mass) as fuel, was investigated using chemical kinetic simulations at conditions representative a two-stroke marine diesel engine. purpose address two the most prominent issues with making practical fuel for applications: difficulty igniting ammonia, safety concerns regarding its volatility toxici...

Increased understanding is needed with respect to soot formation from high pressure diesel sprays as emissions standards become increasingly stringent and require complex methods for its reduction. Understanding soot formation and its spatial distributions is necessary to advance fundamental spray combustion knowledge. Given that the underlying nature of high pressure combusting diesel sprays r...

Nutritional and extractable oil profile in seeds of Sesamum indicum L. Moringa oleifera Lam. were investigated using standard biochemical procedures. Proximate analysis revealed % crude protein contents 24.32% S. while M. had 27.66%. Crude lipid analyzed 47.78% was obtained 28.87% oleifera. carbohydrate with 37.89% oleifera, it 34.51%. fibre 11.32% 9.37% identified Higher ash content 9.13% 7.62...

The aim of this study was to produce microbial oil from Lipomyces starkeyi DSM 70296 grown in hemicellulose hydrolysate (H-H). Glucose and xylose were used for batch, fed-batch, repeated fed-batch, and continuous cultures, and H-H was tested at continuous culture. The highest cell and lipid concentrations of 85.4 and 41.8g/L, respectively, were obtained using repeated fed-batch strategy. Contin...

BACKGROUND Several researchers have searched for subgroups in the heterogeneous population of patients with non-specific low back pain (LBP). To date, subgroups have been identified based on psychological profiles and the variation of pain. METHODS This multicentre prospective observational study explored the 6- month clinical course with measurements of bothersomeness that were collected fro...
