The absorptive corrections resulting from the rescattering of a heavy flavour (the so-called nuclear absorption) are usually calculated with a probabilistic formula valid only in the low energy limit. We extend this formula to all energies using a quantum field theoretical approach. For charmonium and bottonium we find that the absorptive corrections in the rigorous treatment are very similar t...

The purpose of this research is to address the absorptive capacity of individual knowledge workers in terms of their personal knowledge work practices. The purpose will be achieved by examining individual knowledge worker practices as they relate to the various dimensions of absorptive capacity, the SECI model of knowledge creation, and the communication channels used in their personal knowledg...

Proper organ homeostasis requires tight control of adult stem cells and differentiation through the integration of multiple inputs. In the mouse small intestine, Notch and Wnt signaling are required both for stem cell maintenance and for a proper balance of differentiation between secretory and absorptive cell lineages. In the absence of Notch signaling, stem cells preferentially generate secre...

A membrane fraction enriched in apical endosomal tubules was isolated from absorptive cells of suckling rat ileum and used as an immunogen to generate anti-endosome monoclonal antibodies. By immunofluorescence, one of these antibodies bound exclusively to the region of the apical endocytic complex in ileal absorptive cells, but not to other cell types. Immunoblot analysis showed the antigen as ...

Caco-2 cells are models of absorptive enterocytes. The net transport of fluid from apical to basolateral surfaces results in 'domes' forming in differentiated monolayers. Here, the effect of Campylobacter jejuni on this process has been examined. C. jejuni caused no changes in short-circuit current upon infection of Caco-2 cell monolayers in Ussing chambers. Thus, no active secretory events cou...

Intestinal Na and H2O fluxes and blood flow were determined in extrinsically denervated or innervated ileum of fed dogs during intra-arterial (0.2, 2, 20 micrograms min-1) or intraluminal (4, 40, 400 micrograms ml-1) morphine sulphate infusion. 3H2O and 22Na were used to determine unidirectional fluxes and 3H2O clearances were used to determine total segmental and absorptive site blood flow. Ne...

With the increasing speed of competition, knowledge management has become a critical competitive weapon. The process of knowledge transfer between business units is an essential aspect of knowledge management. The ability to transfer knowledge internally is one of the main competitive advantages of multinational corporations (MNCs). In this paper we will explore knowledge transfer and absorptiv...

BACKGROUND Training has been the focus of considerable conceptual and empirical attention but is considered a relevant factor for competitive edge in companies because it has a positive impact on business performance. This study is justified by the need for deeper analysis of the process involving the transfer of training into performance. This paper's originality lies in the implementation of ...

Abstract We introduce a generalized concept of solutions for reaction–diffusion systems and prove their global existence. The only restriction on the reaction function beyond regularity, quasipositivity mass control is special in that it merely controls growth cross-absorptive terms. result covers nonlinear diffusion does not rely an entropy estimate.
