Human milk contains large quantities of iron-binding protein, of which the greater proportion is lactoferrin, though small amounts of transferrin are also present. Three samples of human milk with unsaturated iron-binding capacities of between 56 and 89% had a powerful bacteriostatic effect on Escherichia coli O111/B4. The bacteriostatic properties of milk were abolished if the iron-binding pro...

The objectives of Exp. 1 were to determine the effects of production system and genotype on pig performance and health. Sows were bred, gestated, farrowed, and lactated in either an intensive indoor or an intensive outdoor production system. The three dam genotypes of pigs used in each environment were PIC Camborough-15 (C-15), PIC Camborough Blue (CB), and Yorkshire x Landrace (YL). All pigs r...

W E REPORTED EARLIER1 that scorbutic guinea pigs showed normocytic and normochromic anemia with normoblastic reaction of bone marrow, diminished plasma iron, decreased iron binding capacity of plasma, increased free erythrocyte protopofl)hyrin and a low sideroblast percentage with high hemosiderin content of bone marrow. These changes could not be attributed to inanition, intestinal hemorrhage,...

The spin state of cytochrome P-450 ferric iron in uiuo and in oitro was examined in freshly prepared liver microsomes from rabbit, guinea pig, hamster, mouse, and rat by low temperature electron paramagnetic resonance CEPR) spectroscopy and compared with room temperature difference spectral changes. Simple liquids of known relatively “pure” type I, reverse type I, and type II tcyclohexane, buta...

M. Dudek, AGH University of Science and Technology, Krakow, Faculty of Management, Poland In the blast-furnace production, raw materials may account for approx. 50 % of the pig-iron manufacture costs. Therefore, any, even small, saving in the sphere of raw material purchasing will translate into the reduction in the cost of the pig-iron manufacture. The selection of appropriate supply sources a...

The Pau Branco mine supplies two blast furnaces with iron ore lumps, and currently, charcoal consumption for pig iron production accounts for 47% of the blast furnaces’ operational cost. A geometallurgical model is presented to support an economic study considering reserve volumes, product quality, and operational costs based on the metallurgical performance of different iron ore typologies. Sa...
