    Kumar, V.; Pandey, R.N.; Upadhyay, S.N. (Taylor and Francis Inc., 1998)
    Endothelial cells, lining the entire vascular system, respond to change in concentration of specific agonist like adenosine triphosphate (ATP) by increasing cytosolic Ca2+ concentration, producing prostacyclin, endothelium ...
  • On Multiple-Objective Optimization with Generalized Univexity 
    Mishra, S.K. (1998-08-01)
    A multiple-objective optimization problem involving generalized univex functions is considered. Kuhn-Tucker type sufficient optimality conditions are obtained for a feasible point to be an efficient or properly efficient ...
  • Interfaces in icosahedrally related structures: problems and prospects 
    Mandal, R.K. (Indian Acad of Sciences, 1999-05)
    Icosahedral quasicrystals are frequently observed to coexist with their related phases like pentagonal/decagonal quasicrystals and rational approximant structures. Owing to this, they have common interfaces. The crystallography ...
