    Static Properties of Quark Solitons

    It has been conjectured that at distances smaller than the confinement scale but large enough to allow for nonperturbative effects, QCD is described by an effective SU(Nc×Nf)L×SU(Nc×Nf)RSU(N_c {\times} N_f)_L\times SU(N_c {\times} N_f)_R chiral Lagrangian. The soliton solutions of such a Lagrangian are extended objects with spin 12{1\over 2}. For Nc=3N_c{=}3, Nf=3N_f{=}3 they are triplets of color and flavor and have baryon number 13{1\over3}, to be identified as constituent quarks. We investigate in detail the static properties of such constituent-quark solitons for the simplest case Nf=1,Nc=3N_f{=}1, N_c{=}3. The mass of these objects comes from the energy of the static soliton and from quantum effects, described semiclassically by rotation of collective coordinates around the classical solution. The quantum corrections tend to be large, but can be controlled by exploring the Lagrangian's parameter space so as to maximize the inertia tensor. We comment on the acceptable parameter space and discuss the model's further predictive power.Comment: 8 pages + 1 PostScript figure; plain LaTe

    The Virtues of Balm in Late Medieval Literature

    Get PDF
    This article argues that balm, or balsam, was, by the late medieval period, believed to be a panacea, capable of healing wounds and illnesses, and also preventing putrefaction. Natural history and pharmacological texts on balm from the ancient and late antique periods emphasized specific qualities of balm, especially its heat; these were condensed and repeated in medieval encyclopedias. The rarity and cost of balsam, from antiquity through the medieval period, and the high rate of counterfeiting also demonstrate its high demand and significance in medicine and religious ritual. Travel writing and itineraria from the early and central medieval periods added a new layer to ideas about the capabilities of balsam: that it originated from a Christian miracle and was a particularly Christian plant

    Loosely bound hyperons in the SU(3) Skyrme model

    Full text link
    Hyperon pairs bound in deuteron like states are obtained within the SU(3) Skyrme model in agreement with general expectations from boson exchange models. The central binding from the flavor symmetry breaking terms increases with the strangeness contents of the interacting baryons whereas the kinetic non-linear σ\sigma-model term fixes the spin and isospin of the bound pair. We give a complete account of the interactions of octet baryons within the product approximation to baryon number B=2B=2 configurations.Comment: 35 pages REVTEX including 2 figs, with 3 further figs available on request from [email protected] or from [email protected] SI-94-TP3S2; STPHY-Th/94-

    Inundation mapping – a study based on December 2004 Tsunami Hazard along Chennai coast, Southeast India

    Tsunami impact study has been undertaken along Chennai coast starting from Pulicat to Kovalam. The study area Chennai coast is mainly devoted to prepare large scale action plan maps on tsunami inundation incorporating land use details derived from satellite data along with cadastral data using a GIS tool. Under tsunami inundation mapping along Chennai coast an integrated approach was adopted to prepare thematic maps on land use/land cover and coastal geomorphology using multispectral remote sensing data. The RTK dGPS instruments are used to collect elevation contour data at 0.5 m intervals for the Chennai coast. The GIS tool has been used to incorporate the elevation data, tsunami inundation markings obtained immediately after tsunami and thematic maps derived from remote sensing data. The outcome of this study provides an important clue on variations in tsunami inundation along Chennai coast, which is mainly controlled by local geomorphologic set-up, coastal zone elevation including coastal erosion protection measures and near shore bathymetry. This study highlights the information regarding most vulnerable areas of tsunami and also provides indication to demarcate suitable sites for rehabilitation

The activated charcoal was produced in a stainless steel retort with electrical heater at the temperature of 7000C, 8000C and 9000C and for activation used NH4HCO3 with its consentration 0,5; 1,0; 3,0; 5,0 and 10% respectively.The best quality of the activated charcoal produced when the activation temperature was 9000C with the NH4HCO3 1,0 %. The yield of activated charcoal was 5,90%, moisturecontent 6,39 %, ash content 9,15 %, volatile matter 8,81 %, fixed carbon 82,04 %. Adsorptive capacity of iodine was 1154,4 mg/g, NH3 25,08 %, CHCl3 42,28 %, CCl4 51,74 %, benzene 49,10% and methylene blue 138,80 - 319,00 mg/g. Surface area was 1143,7 m2/g. The most abundance of particle size was 4,00 - 5,65 micron and pore volume 16,00 - 22,62 micron. High and diameter pore was 37,49 and 22,52 micron

    Association of human cytomegalovirus proteins IRS1 and TRS1 with the viral DNA polymerase accessory subunit UL44

    Multiple proteins interacting with DNA polymerases orchestrate DNA replication. Human cytomegalovirus (HCMV) encodes a DNA polymerase that includes the presumptive processivity factor UL44. UL44 is structurally homologous to the eukaryotic DNA polymerase processivity factor proliferating cell nuclear antigen (PCNA), which interacts with numerous proteins. Previous proteomic analysis has identified the HCMV protein IRS1 as a candidate protein interacting with UL44. Nuclease-resistant reciprocal co-immunoprecipitation of UL44 with IRS1 and with TRS1, which has an amino terminus identical to that of IRS1, was observed from lysate of cells infected with viruses expressing epitope-tagged UL44, epitope-tagged IRS1 or epitope-tagged TRS1. Western blotting of protein immunoprecipitated from infected cell lysate indicated that epitope-tagged IRS1 and TRS1 do not associate simultaneously with UL44. Glutathione S-transferase pull-down experiments indicated that IRS1 and TRS1 interact with UL44 via a region that is identical in both proteins. Taken together, these data suggest that IRS1 and TRS1 may compete for association with UL44 and may affect UL44 function differentially
