Scaling and Angular Distributions for 2-Body E760 Data

The following are the results of 2-body FNAL analyses performed on E760 1991 data. The various reaction modes (¯pp ! XY ) include ß o ß o , ß o j, ß o fl, jfl, jj, and flfl. The angular distributions and sample acceptances are shown. In addition, the cross sections in the form doe=dt are shown at cos(` ) = 0 versus center of mass energy p s and fit to a power law. Then the scaling hypothesis, doe=dt ' s \Gammam , is used to look for oscillations in the spectrum. 1 Analysis The data used for these analyses comes from FNAL E760's 1991 run. The ß o ß o and ß o fl events come from special DSTs which were made during the run for calibration purposes. The flfl events were those analyzed by Mika Mazuzawa [1] from the "2GAMDST"s and were compared to feeddown from ß o ß o and ß o fl. The jX modes were analyzed from the neutral DSTs made after the run. The two body data is part of a larger program of charmonium physics in the energy range, 2:9 ! p s ! 4:2 GeV. In ..

Determinants of a regional port-centric logistics hub: The case of East Africa

Demand for port capacity in East Africa is rising rapidly, and possibilities for expansion in the existing ports are limited. Studies indicate that, by 2016, a new port north of Dar es Salaam (Tanzania) should be operational, serving, as a regional hub, the needs of the total (captive and non-captive) hinterland of East African ports. The objective of this article is to assess the economic potential, in terms of logistics costs of alternative hub-port locations. To that effect we first describe the flow of goods in the Nairobi – Durban port range and the landlocked countries; the available inland transport options; and the related transport costs and quality of service aspects. The inland and maritime transport costs are investigated and compared next, for the import-export routings of 18 different trade combinations between six landlocked countries (Uganda, Rwanda, Burundi, DRC Great Lakes/Copper Belt, Zambia and Malawi) and five ports (Mombasa, Dar es Salaam, Durban, Beira and Nacala). The article estimates the parameters of a multinomial logit model by comparing the differences in logistics costs of routings via Dar es Salaam and other ports. A port demand function is derived as a result. The article concludes that, in view of its distance from the arterial maritime container trade routes, the new port could only function as a regional lower-tier hub and distribution centre for the trade of Tanzania and Kenya, and of landlocked countries ranging from Uganda in the north to Zambia in the south. At present, this role is mostly played by ports in the Middle East, whereas East African ports serve merely as transit points.

Synthesis and Processing of Bovine Herpesvirus-1 Glycoprotein H

The translation product of the bovine herpesvirus-1 (BHV-1) gH gene was identified and characterized. Synthetic peptides were used to generate specific antisera and a glycoprotein of 108K was precipitated by one of the antisera. Cross-immunoprecipitations with monoclonal antibodies to BHV-1 glycoprotein gp108 and the anti-gH peptide antiserum demonstrated that gp108 is the translation product of the gH open reading frame. Glycoprotein gH synthesis and intracellular processing was analyzed in infected Madin-Darby bovine kidney cells using anti-gp 108 monoclonal antibodies. Glycoprotein gH is expressed as a beta-gamma protein and could be detected by radioimmunoprecipitation as early as 2 hr postinfection. Cotranslational N-glycosylation of gH is essential for the recognition by monoclonal antibodies, suggesting that N-linked glycans are involved in protein folding or that they are targets for most of monoclonal antibodies used in this study
