Previous research has shown that methane may have been sustained at high concentrations in the Archean atmosphere, helping to offset lower insolation and solve the faint young sun problem. However, recent updates to the HITRAN (High-Resolution Transmission) line database have significantly increased the shortwave absorption by CH4 in comparison to older versions of the database (e.g. HITRAN 200...

In this paper we propose a three–level computational equilibrium model that allows to analyze the impact of the regulatory environment on transmission line expansion (by the regulator) and investment in generation capacity (by private firms) in liberalized electricity markets. The basic model analyzes investment decisions of the transmission operator (TO) and private firms in expectation of an ...

the iranian poultry sector has experienced many significant structural changes in recent years. such changes may have influenced price dynamics and transmission of shocks through marketing channels especially on retail markets. this paper investigate price transmission, threshold behavior and asymmetric adjustment in poultry sector of ardebil (ar), east azerbaijan (ea) and west azerbaijan (wa) ...
