these experiments examined the effects of pre-test intra dorsal hippocampus (intra-ca1) administration of gabaa receptor agonist and antagonist, muscimol and bicuculline respectively, on state-dependent learning induced by lithium. male nmri mice were trained in a one-trial step-down inhibitory avoidance task, and immediately after training they received ip injections of either saline (10 ml/kg...

  Background: Intra-operative radiation therapy (IORT) is the transfer of a single large radiation dose to the tumor bed during surgery with the final goal of improving regional tumor control. This study aimed to investigate the safety, effectiveness and economic evaluation of intra-operative radiation therapy.   Methods : The scientific literature was searched in the main biomedical databases ...

We propose a novel probabilistic framework for semantic video indexing. We define probabilistic multimedia objects (multijects) to map low-level media features to high-level semantic labels. A graphical network of such multijects (multinet) captures scene context by discovering intra-frame as well as inter-frame dependency relations between the concepts. The main contribution is a novel applica...

1. Introduction During the negotiation and implementation stages of the " 1992 " single market programme, prominent economists anticipated that the pressures for industrial restructuring among EU[1] countries would be considerably stronger than during previous episodes of European integration. Krugman (1987, p. 364) put it as follows: " The question now is whether the further expansion of trade...

  A fuzzy goal programming-based approach is used to solve a proposed multi-objective linear programming model and simultaneously handle two important problems in cellular manufacturing systems, viz. cell formation and layout design. Considerations of intra-cell layout, the intra-cell material handling can be calculated exactly. The advantages of the proposed model are considering machining cos...

spreading faba bean (vicia faba) cultivation can enhance the sustainability of cropping systems and have other important benefits. however, there is little information on the various aspects of production management for this crop. then, this experiment was carried out to study the response of some agronomic characteristics of faba bean cv barakat to inter- (15, 30, 45 and 60 cm) and intra-row (...

Among non-oil exports and in trade arena, drug has always been strategic importance and most government especially industrialized countries pay special attention to its production and trade issues. Thus, having a comprehensive view from economic perspective to this section is essential for suggesting intervention. This was a descriptive-analytical and panel study. In this study, gravity model i...
