In order to systematically understand the qualitative and quantitative behaviour of chemical reaction networks, scientists must derive and analyse associated mathematical models. However, biochemical systems are often very large, with reactions occurring at multiple time scales, as evidenced by signalling pathways and gene expression kinetics. Owing to the associated computational costs, it is ...

Polyester torba tekniği kullanılarak yapılan bu çalışmada, mısır silajının rumendeki inkübasyonundan elde edilen veriler silajların rumende parçalanabilirlik kinetiğininin doğrusal olmayan alternatif modeller önermek için yürütüldü. Bu mısırın orta çiçeklenme, süt olum ve sert hamur olmak üzere üç farklı olgunluk döneminde hasat edilmesiyle verileri kullanılmıştır. Orskov modeli, Monomolecular,...

The autoxidative formation of 7-ketocholesterol and diols from aqueous cholesterol dispersions and from cholesterol monomolecular films has been studied as a function of time. The rate of oxidation of cholesterol is much faster at the surface than in the bulk. Whereas more than one-half of the cholesterol is oxidized at the surface within 8 hr at room temperature, no noticeable reaction was obs...

Nonlinear optical techniques (second-harmonic and sum-frequency generation) have been used to study the structure of organic molecules that are confined and compressed between a lens and a flat surface. The molecules studied include self-assembled monolayers of n-octadecyltriethoxysilane and Langmuir-Blodgett films of stearic acid, octadecylalcohol, octadecylamine, and a liquid-crystal molecule...
