Direct Reduced Iron Industry in India - Problems and Prospects

India is the largest producer of Direct Reduced Iron in the world with annual capacity of nearly 10 Mt comprising coal and gas based DRI plants. India has the largest coal based DRI capacity. The industry is faced with problems relating to raw materials availability and their quality. An important consideration for overcoming this problem will be to install pelletising plants. Despite all odds, the outlook appears to be bright for the DRI industry as the steel production in India is expected to reach about 50 Mt by the year 2010. The paper deals with coal based DRI industry

Food Safety Program: Endrin Monitoring in the Mississippi River

Twelve successive monthly samplings and analyses of representative fish and shellfish and of mud and water from the lower Mississippi River showed neither a high concentration of endrin nor a time-ordered change in the concentration. The general absence of endrin from the samples indicated no significant contamination

Unknown metabolic inhibitor contained in the brain of starved frog Rana hexadactyla

The O consumption of brains from frogs starved for 60 days was examd. Brain and liver from well-​fed frogs consumed 400.8 and 309.9 μl of 0​/g​/hr, resp. The resp. values for starved subjects were 213.8 and 67.7 μl. of 0​/g​/hr. Adding exts. of starved tissue to well-​fed tissue decreased greatly the O consumption of the latter. Exts. from well-​fed brain added to starved ext. increased the activity of the latter significantly. Thus, there may be a metabolic inhibitor in the brain of starved frogs and a stimulating factor in the brain of well-​fed frogs

Forming of simple components of silicon carbide, Silicon nitride and silicon by slip casting methods

The slip casting studies on well optimised slips of Sic, Si3N 4 and silicon have been applied to fabricate some components with complicated shapes eg. after burner catalytic ignitor housings, super charger stator rings etc. The green densities of slip cast bodies of Sic, Si3N4 and silicon slips ranges from 50 to 60 of theoretical value, indicating that good compacts can be obtained by the slip casting procedure by using these optimised slips
