this paper addresses the issue of the relationship between the type of organizational / economic structure and organizational entrepreneurship in small- and- medium- sized enterprises (smes). it further provides discussions on mechanical/organic structures as well as organizational entrepreneurship and knowledge structure. in another section, the methodology of the research includes hypotheses,...

a stratigraphic section from the tirgan formation was selected in arkan village nearby bojnourd city in order to study echinoderm fauna systematically. many specimens of echinoderms, especially toxasteridae which is associated with brachiopods were collected and studied systematically in this paper. microscopie slides were also prepared and studied. all slides contain benthic foraminifers and c...

caesarean section (c-section) rates have been increasing dramatically in the past decades around the world. this increase has been attributed to multiple factors such as maternal, socio-demographic and institutional fac-tors. therefore, this study examines the impact of maternal, socio-demographic and relevant characteristics on caesar-ean delivery in the northern region of bangladesh.this stud...

The two simplest nontrivial Vassiliev knot invariants (see [Vassiliev 92, Birman and Lin 93]) are of type two and type three. These invariants have been studied from various angles: for instance, combinatorial formulæ for evaluating them have been derived, and simple bounds in terms of crossing number have been obtained (see e.g., [Polyak and Viro 94, Lannes 93, Willerton 97]). In this work, th...

Many science and engineering problems can be formulated as optimization problems that are governed by m-flow type PDEs (multitime evolution systems) and by cost functionals expressed as curvilinear integrals or multiple integrals. Though these functionals are mathematically equivalent on m-intervals, their meaning is totally different in real life problems. Our paper discusses the m-flow type P...

We discuss the associated W±H∓ production in pp collision for the Large Hadron Collider. A complete one-loop calculation of the loop-induced subprocess gg → W±H∓ is presented in the framework of the Minimal Supersymmetric Standard Model (MSSM), and the possible enhancement of the hadronic cross section is investigated under the constraint from the squark direct-search results and the low-energy...

A reappraisal is made of the Anthurium Schott species with palmately divided leaves with 3 or more segments free to the base (i.e. palmatisect leaves), previously recognized as section Dactylophyllium Schott (Engler), as well as those species with 5 or more segments united at the base (i.e. palmatifid leaves), formerly placed in section Schizoplacium Schott (Engler). New molecular data indicate...
