The methanolic extract of the aerial parts of Salvia leriaefolia (labiatae) afforded 5-hydroxy-4´, 6, 7-trimethoxy flavone (Salvigenin) and (5,4´-dihydroxy-7-methoxy flavone (Genkwanin). The structures of the isolated compounds were elucidated using 1 and 2 D-NMR, IR, UV and MS.

neither damage mechanics model nor elastoplastic constitutive law can solely describe the behavior of concrete satisfactorily. in fact, they both fail to represent proper unloading slopes during cyclic loading. to overcome the disadvantages of pure plastic models and pure damage approaches, the combined effects need to be considered. in this regard, various classes of plastic-damage models have...

The nature of value and how R&D/technology organizations provide value are considered. Value is defined in terms of three dimensions: quality, productivity, and innovation. This framework provides the basis for formulation of value strategies in terms of where value is to be provided, how it will be provided, enterprise designs that support these intentions, benchmarking to identify gaps, and s...

The prevalence of diversity training has not been matched by empirical research on its effectiveness. Among the most notable gaps are an absence of attention to its impact on discrimination and limited consideration of organizational-level factors. Results from employee surveys across 395 healthcare organizations reveal an effect of the extent of diversity training in organizations on ethnic mi...

In this study, we examine the relationships between new ventures’ ties with service intermediaries (i.e., technology service firms, accounting and financial service firms, law firms, and talent search firms) and their product innovation in the context of a technology cluster. Because service intermediaries sit at the intersection of many firms, organizations and industries, they maintain extens...
