Graphite ore collected from Hunan province, south China was characterized by chemical analysis, X-ray diffraction, and optical microscopy. Rougher and multi-stage flotation tests using a mechanical flotation cell and a flotation column containing an additional centrifugal force field were carried out to promote its grade and economic value. In rougher flotation, both the mechanical flotation ce...

In this study the nutritional values of three woody leafy vegetables commonly consumed in the south eastern Nigeria were investigated. Fresh edible leaves of Heinsia crinata, Lasienthera africana and Pterocarpus mildbraedii were collected from the wild stands. Proximate analyses were carried out to evaluate their nutritional values vis-à-vis moisture, ash, fibre, protein, lipid, carbohydrate an...

Fluoride and calcium concentrations in maternal plasma and in placental tissue were determined in 30 healthy women residing in an area with a relatively low water and air fluoride (fluorine) content. The mean fluoride concentrations in maternal plasma and in marginal and central parts o f placenta were 4.27 pMlL, 42.1 pglg of ash, and 33.7 pglg of ash, respectively. The mean calcium concentrati...

The value of biogas produced at small scale facilities, such as farm scale biogas plants, can increase by upgrading it to vehicle fuel quality. However, commercial upgrading technologies available today are very costly for small scale applications. Ash from combustion of wood fuels has a high content of Ca, which indicates favourable conditions for a high CO2 uptake capacity from biogas. The ob...

AIM The study was undertaken to find out the gross composition, nitrogen distribution, and selected mineral content in Surti goat milk, and its comparison was made between cow and buffalo milk. MATERIALS AND METHODS Goat milk samples of Surti breed and buffalo milk samples were collected during the period from July to January 2014 at Reproductive Biology Research Unit, Anand Agricultural Univ...

Lithium borate glasses with fixed alkali content of 10 Mole % and different modifiers have been prepared. To compare the role of fly ash as a glass modifier the content of glass modifier PbO, Al2O3 have been kept same to 5 mole %. To investigate the structure FTIR and UV-VIS spectra of prepared samples have been taken. From optical data optical band gap and cutoff wavelength have been calculate...

Phosphorus (P) is present in different chemical compounds in animal feeds, and the solubility and digestibility of these different compounds are known to differ significantly. Animal protein ingredients generally have a high P content and are major contributors to total P of feeds for fish and other domestic animals. Estimation of different P compounds in these ingredients could help to improve...

In thermochemical utilization of biomass, ash produced during the process is a major problem that can result in decreased performance and increased in difficulty during operation. Preliminary assessment of potential ash related troubles prior to the use of a specific biomass is valuable, even if it is only a general guideline. In this work, tendency of ash slagging, fouling and agglomeration in...

Fly ash is a waste produced mostly from the burning of coal in thermal power stations, which contributes to environmental pollution. Also, a number of studies have been conducted to investigate the influence of randomly oriented fibers on the engineering behavior of coarse grained and fine grained soils. The influence of randomly oriented polypropylene fibers on the engineering behavior of soil...

Effects of different drying methods (sun drying, oven drying & rural cooker smoking) and meat size (block, flat & mince) on the nutrient content of beef was investigated with cooked cured (CC) or noncooked cured (NC) beef. Both physical and chemical assessment were done to assess the quality of meat. Organoleptically all the samples were in acceptable condition upto 120 days of storage time. Th...
