Only small numbers of calves were fattened on whole milk alone, both in western Europe and Great Britain, until the 1960’s, d-hen suitable milk-substitute diets were developed. The lorn iron content of milk made calves anaemic (Blaxter, Sharman & MacDonald, ‘957) and lowered the myoglobin content of the muscle tissues. This resulted in white meat. In the course of time this whiteness bccame a m...

A modelforparticle nucleation andgrowth in a thermalplasma reactor is discussed. A nondimensionaIform of the aerosol general dynamic equation is derived under a set of simplifying assumptions which are appropriate to plasma powder synthesis, and the resulting set of equations is solved numerically. The results are converted to dimensional form for the case of iron powder, for which experimental...

Methodology has been developed for the bulk and trace element analysis of spices such as curry powder and turmeric powder originated from Sri Lanka by the k0-standardization method (INAAk0) and by energy dispersive X-ray fluorescence (EDXRF). SRM 1572 citrus leaves was used to check the accuracy of the results obtained by the two nuclear techniques. The elements determined quantitatively in the...

The very large expansion upon adsorption of liquids, up to 160% in cell volume, has been observed in the iron(iii) trans,trans muconate MIL-89 [(MIL = Material Institut Lavoisier]. The structure of lutidine-containing MIL-89 (lutidine = 2,6-dimethylpyridine) has been determined using X-ray powder diffraction and computer simulations. Finally, the consequences of adsorption of various polar and ...

The reduction of Fe2O3 powder at the top layer by the volatiles from high volatile (HV) bituminous coal at the bottom layer of a multilayer powder geometry including a separating alumina layer was studied. The simultaneous effects of the alumina layer thickness, time, temperature and the weight of coal on the amount of reduction and coal devolatilization were studied by implementing a rotatable...

The synthesis of iron oxide nano-particles by direct thermal decomposition was studied. Simultaneous thermal analysis and Fourier transform infrared spectroscopy results confirmed the formation of iron-urea complex, and disclosed iron oxide formation mechanism. Calcination of the iron-urea complex at 200°C and 250°C for 2 hrs. resulted in the formation of maghemite along with hematite as a seco...

optimization of process parameter is one of the ideal goals in laser sintering. the results of this process were measured as output parameters like: density, micro hardening, macro hardening, tension, roughness, stiffness, balling. in this paper, the influence of input parameter such as laser power, scan speed, material powder and etc are surveyed on output parameter like balling affection and ...
