The supersymmetric version of the Nambu-Jona-Lasinio model is investigated in connection with the chiral symmetry breaking induced by a soft SUSY breaking term. It is found that the broken chiral symmetry due to the soft breaking term is restored at suitably high temperature and the symmetry restoration occurs as first-order phase transitions. The critical temperature at which the chiral symmet...

The thermal signatures of free-surface wakes observed in the open ocean show that the recovery of the cool skin layer is related to the degree of surface mixing and to ambient environmental conditions. Wakes produced by two surface-piercing cables of O(10 -2 m) in diameter a e analyzed using infrared imagery. Under low-wind-speed conditions when the swell and surface current were aligned, the w...

polyurethane/zeolite 13x nanocomposite films were fabricated using solution casting method. the synthesized nanocomposite films were structurally characterized using sem, tga and tensile analysis. sem images showed appropriate distribution of nanocrystalline zeolite particles within polyurethane matrix. better thermal stability of nanocomposite films in comparison to neat polyurethane was shown...

poly methyl methacrylate (pmma) is the most common material used in prosthodontics. several studies indicate a breakdown of the number of very high resin bases after 2 to 3 years to avoid breaking bass and several attempts have been made, such as altering the chemical structure of resin by adding causes cross linking or copolymerization. the innovative method for improving the physical properti...

Wound healing effects of 50% ethanol extract of dried whole plant of Bacopa monniera (BME) was studied on wound models in rats. BME (25 mg/kg) was administered orally, once daily for 10 days (incision and dead space wound models) or for 21 days or more (excision wound model) in rats. BME was studied for its in vitro antimicrobial and in vivo wound breaking strength, WBS (incision model), rate o...

introduction: laser tissue soldering is a new technique for repair of various tissues including the skin, liver, articular cartilage and nerves and is a promising alternative to suture. to overcome the problems of thermal damage to surrounding tissues and low laser penetration depth, some exogenous chromophores such as gold nanoshells, a new class of nanoparticles consisting of a dielectric cor...
