A Search for Vector Diquarks at the CERN LHC

Resonant production of the first generation vector diquarks at the CERN Large Hadron Collider (LHC) is investigated. It is shown that the LHC will be able to discover vector diquarks with masses up to 9 TeV for quark-diquark-quark coupling alpha_(D)=0.1 and 4 TeV for alpha_(D)=5x10^(-4).Comment: 9 pages, 4 tables, 4 figure

High efficiency indirect shoot regeneration and hypericin content in embryogenic callus of Hypericum triquetrifolium Turra

A method to induce indirect regeneration from Hypericum triquetrifolium Turra was described in the present study. Callus was induced from cotyledon explants of 35 days old aseptic seedlings on semisolid MS supplemented with IAA (0.5 mg.L-1) combined with BAP (2 mg.L-1). Meristemoids developed on the surface of callus by decreasing of the cytokinins and plantlet regeneration with 100% frequency through these embryogenic calli occured in semi-solid medium when the PGRs were removed completely. Embryogenic calli obtained during the experiments were analyzed for their hypericin content. And they were found to produce hypericin as 48 ìg/g DM. Regenerated plantlets were rooted in MS containing 1 mg/L IAA. The highest percentages (94%) of survival of transferred plantlets to freeliving circumstances were limited when they were acclimatized in sand : peat : perlite (1:1:1; v/v/v) mixture

The effectiveness of BD Vacutainer® Plus Urinalysis Preservative Tubes in preservation of urine for chemical strip analysis and particle counting.

Introduction: The aim of this study was to evaluate the stability of urine collected in preservative tubes for chemistry strip analyses and particle counting to determine whether the transport of urine samples with all of their constituents is possible. Materials and methods: 275 pathologic urine specimens were included. Each urine sample was evaluated after 4, 8, 12, 24, and 48 hours of storage in BD Vacutainer® Plus Urinalysis Preservative (BD UAP) tubes and compared with refrigeration at 4 °C. All analyses were peformed on H-800 and FUS-200 automatic modular urine analyzers (Dirui Industry, Changchun, China). The kappa coefficients (?), false positive (FP) and false negative (FN) rates were evaluated. ? > 0.8 was accepted as good agreement. Results: Haemoglobin (Hb), leucocyte esterase (LE), and protein (Pro) analyses should be performed within 4 hours, whereas glucose (Glc) was stable until the end of 48 hours in both storage conditions. Nitrite (Nit) was well preserved in BD UAP tubes for 24 hours but was stable only up to 8 hours at 4 °C. Bilirubin (Bil) had very high FN rates even at 4 hours in both conditions. The particle counting showed high FN rates for white blood cells (WBC) and red blood cells (RBC), whereas squamous epithelial cells (EC) were stable up to 8 hours in both conditions. Conclusions: Preanalytical requirements for both urine chemical strip analyses and particle counting in a unique sample were not met in either condition. Thus, the transfer of urine samples for centralization of urinalysis is not yet feasible

Copper etching with cupric chloride and regeneration of waste etchant

Copper etching is considerably important process in electronics industry. particularly in the fabrication of printed circuit board. Various etchants can be used for this purpose, but nowadays cupric chloride is more accepted etchant, because of its high etch rate and easy regeneration properties. In the present study, copper etching process with cupric chloride etchant was investigated. In the etching of copper, the most important etching parameter is etch rate, therefore the investigation was based on the various effects on etch rate. The influence of etchant concentration, additives and etching temperature were examined. It is also important to regeneration/recycle of waste etchant from environmental point of view. Thus, various cupric chloride etchant regeneration processes were investigated. (c) 2005 Elsevier B.V. All rights reserved
