Studies on the mechanism of enzymatic hydrolysis of cellulosic substances
Biotechnology and Bioengineering , Vol. 21 (1)
Most cellulosic substances contain appreciable amounts of cellulose and hemicellulose, which on enzymatic hydrolysis mainly yield a mixture of glucose, cellobiose, and xylose. In this paper, studies...

Para-Bose coherent states
Journal of Mathematical Physics , Vol. 19 (10)
In place of the usual commutation relation [â,â†]=1 we consider the generalized commutation relation characteristic of the para-Bose oscillators, viz, [â, Ĥ]=Ĥ where Ĥ is the Hamiltonian...
