The sealant composition includes an unsaturated reactive polyolefin, an olefmic polymer, a silane modified polyolefin, inert fillers, calcium oxide, and aging resistors. These components are balanced to produce a sealant having desirable sealing characteristics, high weatherability, desired rheology, low ...
Used for these purposes are: chromic oxide (Whitby and Lang, 1960; Davignon et al., 1968), 51Cr-labelled haemoglobin, and 47Sc (Pearson, 1966). If bone resorption is equal to bone formation, the balance of calcium is very near to zero. If resorption predominates over formation of bone...
The process of making calcium cyanamide involves three raw materials—coke, coal, and limestone— plus nitrogen. The limestone (calcium carbonate) is burned with coal to produce calcium oxide. The calcium oxide is then allowed to react with amorphous carbon in the furnace at 2000°C with the ...
