a-Neo-endorphin anddynorphin immunoreactivities in rat brain were visualized by double antibody immunofluorescence of frozen sections. Antibodies were used that were specific for their respective antigens. The pattern of neuronal immunostaining produced by a-neo-endorphin and dynorphin antisera in adjacent serial sections was completely superimposible. No areas were found in which a-neo-endorph...

Abstract We introduce a stochastic model in which adjacent planar regions A,B merge stochastically at some rate λ(A,B) and observe analogies with the well-studied topics of mean-field coagulation and of bond percolation. Do infinite regions appear in finite time? We give a simple condition on λ for this hegemony property to hold, and another simple condition for it to not hold, but there is a l...

Purpose In a departure from the efficiency theory assumptions implicit in most supply chain risk management (SCRM) literature, this study aims to explore role that external neo-institutional pressures play shaping strategies deployed mitigate transaction cost risks construction chains (CSC). Design/methodology/approach A theory-elaborating case is used investigate how regulatory, normative and ...

security policy-making in critical regions is one of the main concerns of the research centers and academic institutes. security-building in the regions like the caucasus is important because the historical roots of conflict could be seen in the policies of various countries. whenever some manifestations of authoritarianism can be seen, some countries are in the state of cooperative action. how...
