sponge iron (dri) due to the high surface area, often shows a high tendency to re-oxidation and at some cases spontaneous combustion (autoignition). in this work, re-oxidation behavior and autoignition of sponge iron, produced from different types of iron ore has been investigated. isothermal and non-isothermal re-oxidation experiments were carried out on each type of dri and their autoignition...

Carbohydrates are the major source of energy in diets fed to dairy cattle and usually comprise 60 to 70 percent of the total diet. The main function of carbohydrates is to provide energy for rumen microbes and the host animal. A secondary, but essential, function of certain types of carbohydrates is to maintain the health of the gastrointestinal tract. The carbohydrate fraction of feeds is a co...

Introduction: Liver disease results in complex pathophysiologic disturbances affecting nutrient digestion, absorption, distribution, storage, and use. This article aimed to present a classification of metabolic disturbances in chronic liver disease in children?   Materials and Methods: In this review study databases including proquest, pubmedcentral, scincedirect, ovid, medlineplus were been se...

An extracellular enzyme from culture filtrates of Sporotrichum (Chrysosporium) thermophile (A.T.C.C. 42 464) after growth on cellulose or cellobiose was shown to oxidize cellobiose to cellobionic acid in vitro. Lactose and cellodextrins were also efficiently oxidized, but the enzyme was not active against most mono- and di-saccharides. Several redox substances could act as electron acceptors, b...

While a newly isolated bacterium would usually, as a mat ter of bionomic routine, be tested soon for its power of fermentation of various carbohydrates, nothing systematic has been done in this direction with the group of organisms dassed as spirochetes. The lack of investigation along this line may be partly due to the technical difficulties which still surround the cultivation of these organi...
