By the application of HHP; more than 8 log cycle reduction was achieved for E. coli O157:H7 933 and Salmonella FDA in milk and cream of chicken soup in 5 min. Storage of HHP treated milk samples showed absence of both bacteria for 24 h at 4degreesC and for 48 h at 37degreesC. The population of the strains in cream of chicken soup exceeded their initial value after 5 days of storage at 25degreesC. BP1 was combined with HHP and used for inhibition of surviving bacterial species in cream of chicken soup. There was at least 7 log cycle reduction in E. coli O157:H7 933 and Salmonella FDA after 5 and 7 days of storage at 25 C respectively, when compared to HHP alone. Combination of HHP with BP1 extended the shelf life of cream of chicken soup for both bacterial species an additional 2 days at 25 degreesC when compared with HHP treatment alone.

Inactivation of Staphylococcus aureus and Listeria monocytogenes in milk and cream of chicken soup by high hydrostatic pressure and bacteriocins Alpas, Hami (2002-06-01) By the application of HHP; 5.50 and 5.70 log cycle reduction was obtained for S. aureus 485, in milk and cream of chicken soup samples, respectively. Storage of HHP treated milk samples for 24 h at 4degreesC gave positive result for S. aureus 765 where no growth was observed for L. monocytogenes strains. Incubation of food samples for an additional 48 h at 37degreesC showed growth of L. monocytogenes strains as S. aureus strains. When a bacteriocin-based biopreservative (BP1) was combined with pressurizatio...
Discrete approaches in evolution strategies based optimum design of steel frames Hasançebi, Oğuzhan (2007-05-30) The three different approaches (reformulations) of evolution strategies (ESs) have been proposed in the literature as extensions of the technique for solving discrete problems. This study implements an extensive research on application, evaluation and comparison of them in discrete optimum design of steel frames. A unified formulation is first developed to explain these approaches, so that differences and similarities between their inherent search mechanisms can clearly be identified. Two examples from prac...
Theoretical aspects of some 4-[2,6-substituted-9H-purin-9-yl]-2-cyclopentene-1-methanol derivatives as anti-HIV agents Türker, Burhan Lemi; Sudagidan, M (2000-01-01) Some (-)-(1S,4R) -4-[2-amino-6-(substituted)-9H-purin-9-yl]-2-cyclopentene-1-methanol derivatives have been considered for semiempirical treatment at the level of AM1 type calculations. Certain theoretical structure-activity relationship were investigated.
Observation of the Lambda(0)(b) -> J/psi Lambda phi decay in proton-proton collisions at root s=13 TeV Sirunyan, A. M.; et. al. (Elsevier BV, 2020-03-01) The observation of the Lambda(0)(b) -> J/psi Lambda phi decay is reported using proton-proton collision data collected at root s = 13TeV by the CMS experiment at the LHC in 2018, corresponding to an integrated luminosity of 60fb(-1). The ratio of the branching fractions B(Lambda(0)(b) -> J/psi Lambda phi)/B(Lambda(0)(b) > psi(2S)Lambda) is measured to be (8.26 +/- 0.90 (stat) +/- 0.68 (syst) +/- 0.11 (B)) x 10(-2), where the first uncertainty is statistical, the second is systematic, and the last uncertaint...
Use of pimecrolimus to prevent epidural fibrosis in a postlaminectomy rat model Laboratory investigation Cemil, Berker; Tun, Kagan; Kaptanoglu, Erkan; Kaymaz, Figen; Cevirgen, Banu; CÖMERT, AYHAN; TEKDEMİR, İBRAHİM (Journal of Neurosurgery Publishing Group (JNSPG), 2009-12-01) Object. Epidural fibrosis is the scar tissue formed over the dura mater after a laminectomy. Extensive epidural fibrosis may be an important underlying cause of failed back syndrome. Pimecrolimus, an ascomycin derivative, is one of the new classes of immunomodulating macrolactams and was specifically developed for the treatment of inflammatory diseases. This study examined the preventive effects of the local application of pimecrolimus in minimizing spinal epidural fibrosis in a rat laminectomy model.
