Petrogenetic modelling of strongly residual metapelitic xenoliths within the southern Platreef, Bushveld Complex, South Africa
Xenoliths of quartz-absent Fe-rich aluminous metapelite are common within the platinum group element-rich mafic ⁄ultramafic magmatic rocks of the Platreef. Relative to well-characterized protoliths, the xenoliths are strongly depleted in K2O and H2O, and have lost a substantial amount of melt (>50 vol.%). Mineral equilibria calculations in the NCKFMASHTO system yield results that are consistent...
متن کاملThe Effect of Different Methods of Heat Treatments on the Retention of Ascorbic Acid in Carrot and Corn
ABSTRACT: The history of food science, technology and nutrition and their expansion in respect of raw material, processing, finished products and nutritional value goes back to many years and is still the interests of many researchers. In this work ascorbic acid has been taken not only as an important and vital vitamin to be investigated during the course of different heat processes but also as...
متن کاملAn Optimal Selection of Induction Heating Capacitance by Genetic Algorithm Considering Dissipation Loss Caused by ESR (TECHNICAL NOTE)
In design of a parallel resonant induction heating system, choosing a proper capacitancefor the resonant circuit is quite important. The capacitance affects the resonant frequency, outputpower, Q-factor, heating efficiency and power factor. In this paper, the role of equivalent seriesresistance (ESR) in the choice of capacitance is significantly recognized. Optimal value of resonancecapacitor i...
متن کاملPartially Tests during Course Improves the Students Retention of Renal Physiology Knowledge
Background: Longevity of basic medical sciences is a major concern of medical educators and physicians. It has been shown that different learning styles can affect the half-life of the material. This study aimed to evaluate the effect of partially tests during renal physiology course on "the student’s retention of renal physiology knowledge" and "knowledge loss" in pharmacy and medical students...
متن کاملEffect of Joule-Heating Annealing on Giant Magnetoimpedance of Co64Fe4Ni2B19-xSi8Cr3Alx (x = 0, 1 and 2) Melt-Spun Ribbons
In this work, we have studied the influence of dc joule-heating thermal processing on the structure, magnetoimpedance (MI) and thermal properties of Co64Fe4Ni2B19-xSi8Cr3Alx (x = 0, 1, and 2) rapidly solidified melt-spun ribbons. The nanocrystallization process was carried out by the current annealing of as-spun samples at various current densities. As-spun and joule-heated samples were studied...
