The Pricing of Options and Corporate Liabilities

If options are correctly priced in the market, it should not be possible to make sure profits by creating portfolios of long and short positions in options and their underlying stocks. Using this principle, a theoretical valuation formula for options...

A theoretical analysis has been made of the relationship between the inhibition constant (KI) of a substance and the (I50) value which expresses the concentration of inhibitor required to produce 50 per cent inhibition of an enzymic reaction at a specific...

New method for quantitative determination of uronic acids

A new method for determination of uronic acids with meta-hydroxydiphenyl is introduced. It is simpler, quicker, more sensitive, and more specific than other methods, and it needs lesser amounts of fluid. It is recommended for determination of acid mucopolysaccharides...

Theory of rational option pricing

The long history of the theory of option pricing began in 1900 when the French mathematician Louis Bachelier deduced an option pricing formula based on the assumption that stock prices follow a Brownian motion with zero drift. Since that time, numerous...

Selenium: Biochemical Role as a Component of Glutathione Peroxidase

When hemolyzates from erythrocytes of selenium-deficient rats were incubated in vitro in the presence of ascorbate or H2O2, added glutathione failed to protect the hemoglobin from oxidative damage. This occurred because the erythrocytes were practically...
