A theoretical study of the kinetic and mechanism of intramoleccha cychcation of (1)-undeca-7,8-dien-2-yne was performed using MT methods at B3LYP and B3PW91 levels of theory using 6-311g, 6-311C.6-31 IGs*, 6-31I+G, 6-31 I4-SG and 6-3114H-Gs* basis seo. Equilibrium molecular geometries andharmonic vibrational frequencies of the reaccint, transition state and product wens calculated. Theconsidere...

credit enhancements are methods that are used in structured finance for promoting the credit quality of financial instruments. one of the most important mechanisms for improving the credit quality is tranching financial instruments. this mechanism is mentioned as a structural and internal credit enhancement. tranching decreases financing costs and improves the quality of financial instruments. ...

agent-based negotiation is one of the interesting approaches in the field of automated negotiation in the e-commerce world. establishment an automated negotiation needs to develop a mechanism for it and it is obvious that users would accept a mechanism that is reliable alternative for negotiating individual. therefore, the need to developing efficient and reliable agent-based negotiation mechan...

The main objective of the paper is to analyze the effects on economic agents’ behavior deriving from the introduction of financial activities aimed to environmental protection. The environmental protection mechanism we study should permit exchange of financial activities among citizens, firms, and Public Administration. Such a particular “financial market” is regulated by the Public Administrat...

after the second world war one of the most effective ways which could make an important impact on the life of minorities and deprived communities has been positive discrimination. of course, it has been always controversial in terms of its legitimacy as well as its real impact on changes. using positive discrimination to promote women's condition in many countries and fields such as enteri...

The kinetics of toluene hydrogenation over Ni-supported catalysts with various supports was investigated under the wide range of conditions as 130 to 210 °C reaction temperature, 2.6×10-5 to 5.9×10-5 atm partial pressure of hydrogen and 1.4×10-9 to 3.7×10-8 atm partial pressure of toluene. For more study, two kinetics models were also selected and studied to describe the kinetics of this proces...

on the basis of experimental data a kinetic model for the heterogeneous interaction between alkylperoxyradicals and organic compounds in langmuir- hinshelwood approach at room temperature has been offered.the effect of oxygen on the kinetics of process in the presence, [o2]o = 1 x 1011 – 1.6 x 1012 molecules.cm-2, and absence of oxygen has been analyzed. over time the chain degenerate branching...
