Using deterministic methods,rates of genetic gain(△G) and inbreeding(△F) were compared between pure line selection(PLS) and combined crossbred purebred selection(CCPS),for the sire line of a three-way crossbreeding scheme.

Using deterministic methods, rates of genetic gain(△G)and inbreeding(△F )of 18 breeding scheme were compared between pure line selection(PLS)and combined crossbred purebred selection(CCPS) by Monte Carlo, for the sire line of a three-way crossbreeding system, with the same genetic parameters and population size.

Research on gas-phase selective oxidation of p-xylene over Fe-Mo catalyst;

Nano-sized gold catalysts for CO low-temperature oxidation and selective oxidation;

Study of modified VPO catalysts on the selective oxidation of n-butane to maleic anhydride;

The different selectivities,including chemoselectivity,regioselectivity,syn/trans selectivity,diastereoselectivity,and enantioselectivity,of organic reactions under the microwave-assisted and conventional heating conditions are reviewed.

The rate of selective nitration of acetanilide with mixed acid is studied with the help of Uv-Vis spectra.

In this thesis, 3,4-xylidine which is an important organic intermediates widely applied in pharmacy, pesticide, and dye industries, has been prepared by selective nitration and catalytic hydrogenatuion in low pressure, using o-xylene as start material.

The process produces huge amounts of wastes along with a large amount of undesired o-MNT due to the nonselective nitration of toluene.
