E. Kardas, Z. Skuza Czestochowa University of Technology, Faculty of Production Engineering and Materials Technology, Czestochowa, Poland The paper analyses the quality of raw materials used in the production of blast furnace pig iron. The ferruginous sinter and pellets are the basic raw materials used in the process. The paper presents the impact of those raw materials quality on the effective...

1. A method is described for extraction and partial purification of mitochondrial l-3-glycerophosphate dehydrogenase from pig brain. 2. By the criteria that have so far been applied, the extraction and purification procedures do not modify the activity of the enzyme towards artificial electron acceptors. 3. The amounts of acid-liberatable flavine and iron in the preparation were measured. 4. A ...

Article: Each term, when covering the history of management, many students have difficulty identifying with “ancient” management figures such as Frederick Taylor and Frank and Lillian Gilbreth. Even in Birmingham, Alabama, the former “Pittsburgh of the South,” Taylor‟s pig iron studies have little relevance. The bricklaying, sewing, and surgery studies by the Gilbreths fare only slightly better...

A polarographic method for the determination of as little as 1 pig. of gold in blood and serum samples is described. The relative error is 2.1%. After the sample is dry ashed at 550#{176}, the gold is extracted into ether as the chloride, to separate it from interfering copper and iron. A polarogram of the gold sample is obtained in 2 M potassium hydroxide. The method should be applicable to th...

Ductile iron is one of the most important engineering materials, in view of its excellent castability, signifi cantly better mechanical properties and low cost [1, 2]. It represents the fastest growing segment of the iron market. In the medium term, it is to be expected that the market share of nodular iron will level off at 40 % to 45 % [3]. Achieving the full potential of ductile iron require...

Bacteria have evolved a set of highly specialized proteins to capture iron in iron-depleted environments. The acquisition and uptake of iron present in the extracellular milieu of eukaryotic organisms is indispensable for the growth and survival of microbial pathogens in the course of infection. Haemophilus parasuis is the causative agent of Glässer disease, which is responsible for considerabl...

The enterotoxins (ETs) of Clostridium perfringens isolated from enterotoxemic or diarrheic alpacas, pigs, calves, dogs, and horses were obtained from sporulated cell extracts. The ETs from alpaca, pig, and calf isolates were chromatographed on Sephadex G-lOO. Monoclonal antibodies (MAbs) against ETs derived from alpaca, pig, and calf C. perfringens isolates were produced. The MAbs were used...

Abstract We study productivity differences in vertically integrated steel facilities using equipment-level information on inputs and output for each of the main stages value chain. obtain stage-level estimates by estimating a multistage production system then integrate them into facilities. At this level, we do not find statistically significant ownership. This conceals important upstream downs...

Two experiments involving 22 litters were conducted to study the effects of adding ferrous fumarate to the lactation diet on iron level of sow’s milk and on weight gains and hemoglobin levels of suckling pigs. Ferrous fumarate was not effective in increasing iron content of milk, when added to the lactation diet at a level of 1984 mg. of iron per kg. The increase in hemoglobin level observed at...
