There is a general agreement between researchers that particle size of poultry feed should be between the size ranges of 600-900 µm. This study investigated the particle size of poultry feed produced in the Dormaa Municipality of Ghana. A survey was conducted on various feed mills which were made up of nine on-farm mills and five community-based commercial mills. Feed samples were collected fro...

Time resolved laser induced incandescence (LII) technique is used to measure size distribution of soot nanoparticles of candle's flame. Pulsed Nd:YAG laser is used to heat nanoparticles to incandescence temperature and the resulting signal is measured. Mass and energy balance equations are numerically solved to calculate temperature of soot particles in low fluence regime. Assuming Plank black ...

the nanostructured anatase tio2 with high thermal stability was prepared by polymeric sol-gel method without any additives. the particle size distribution of polymeric titania sol was determined by dynamic light scattering (dls). then properties of obtained titania were investigated by tg-dta, xrd, fesem and tem. also, the decolorization capability of resultant anatase was evaluated using methy...

the ability of trees to trap dusts convinces their use for preventing the transport of dust over longer distances. this ability is increasingly important in threatened areas with dust invasion. the purpose of this study was to compare the size and distribution of particles deposited on the leaves surface of fraxinus rotundifolia, platanus orientalis, and robinia pseudoacacia trees, in paveh, we...

areas surrounding mines are severely vulnerable to pollution due to mine explorations, excavations and transportations. nowadays spectrophotometers and spectral reflectance are applied for estimating the concentration of pollutants due to high costs of sampling and laboratory measurements. this research was carried out to determine spatial distribution of lead concentration in soil particle siz...

An attempt has been made in this paper to investigate the effect of particle size distribution on coal flotation kinetics. The effect of particle size (Ps) on kinetics constant (k) and maximum theoretical flotation recovery (RI) was investigated while other operational parameters were kept constant. The relationship between flotation kinetics constant and theoretical flotation recovery with par...

in this study fertilizing potential of municipal solid waste (msw) compost was investigated by the distribution behavior of heavy metals, nutrient elements and salinity content among the different size fractions. therefore, 3 compost samples (each composed of 6 subsamples) were collected from sanandaj msw composting plant. then, the samples were physically divided into seven fractions of differ...

The fine structure of ascitic cells, consisting of 87-92% heterophil, 5-10% eosinophil leukocytes, and 3% macrophages, is well preserved by glutaraldehyde-osmium tetroxide fixation only when the osmolality of the fixative is appropriately balanced. The beta-glycogen particles, 35-45 mmicro in diameter, are found either as large accumulations in the perinuclear region or in a dispersed form in p...
