Analytic-bilinear approach for construction and study of integrable hierarchies is discussed. Generalized multicomponent KP and 2D Toda lattice hierarchies are considered. This approach allows to represent generalized hierarchies of integrable equations in a condensed form of finite functional equations. Generalized hierarchy incorporates basic hierarchy, modified hierarchy, singularity manifol...

the findings indicate that among the main factors affecting job stress the psycho-social, physical and environmental factors are prior to the other factors. also amongst the psychosocial factors, lack of career promotion opportunities with 0.222 has the most weight and a lack of accountability of the management about the employees' concerns with 0.036 has the least weight; amongst the phys...
