Determination of Freshness and Chemical Compositon of Scad (Trachurus trachurus, L. 1758) Stored in Refrigerator [Buzdolabi Koşullarinda Depolanan İstavrit Baligi (Trachurus trachurus, L. 1758)'nin Tazeliginin ve Kimyasal Bileşiminin Belirlenmesi]

This study was carried out to determine the freshness and chemical composition of scad stored at +2C - +4°C. As a result of bacterial activities and chemical changes in fish meat TMAO breaks down to TMA. DMA and FA. In the fish meat the amounts of these compounds are important for the determination of the freshness of fish meat Breakdown of TMAO into DMA and FA has an effect on the properties of the texture of the fish. Hence we attempted to distinguish the textural characteristics of the stored fish with sensorial analysis. It was detected that the results of the sensorial analysis were in parallel with those of chemical analysis. The pH value of fish meat has a very strong effect on connective tissue. With the increase in pH value in fish tissue, enzymes with a bacterial effect become active. The pH value in this study increased as storage time increased in parallel with chemical analysis. After seven days of storage the following average values were recorded; 6.61 pH, 50.4 mg/100g TVB-N, 12.683 mg/100g TMA-N, 3.234 mg/kg FAex, and 4.688 mg/kg FAdest Except FAdest and FAex. all the values were determined to be beyond acceptable values. Investigating the chemical composition of fish meat, and determining the processing and storage conditions have a great importance on human nutrition. Fatty fish with weak tissue has limited cold and frozen storage time. For this reason the chemical composition of the species under study was determined. As a result the fish was found to be with medium fat, high in protein with the following values of 1.73 % fat, 1.48 % ash, 72.15 % moisture and 21.02 % protein on average

Production of scalar and vector bileptons in polarized e(-)gamma and gamma gamma colliders

Bu çalışma,06-09 Eylül 2016 tarihlerinde Bodrum[Türkiye]’de düzenlenen 32. International Physics Congress of Turkish-Physical-Society (TPS) Kongresi‘nde bildiri olarak sunulmuştur.We study the production of doubly charged scalar and vector bileptons which are predicted several beyond the Standard Model scenarios, in polarized high energy e gamma and gamma gamma collisions with the photon originating from Compton backscattering. We analyze the discovery potential and show how the use of polarized beams is to distinguish between scalar and vector bileptons in model-independent framework.Türk Fizik Derneğ

Detector design studies for Turkish accelerator center

Bu çalışma, 06-09, Eylül 2016 tarihlerinde Bodrum[Türkiye]’de düzenlenen 32. International Physics Congress of Turkish-Physical-Society (TPS) Kongresi‘nde bildiri olarak sunulmuştur.The proposed Particle Factory detector at Turkish Accelerator Center (TAC-PF) aims to search for charm physics, CP violation and mixing of D-0 mesons as well as new physics effects by investigating head-on collisions of 1 GeV electron from Energy Recovery Linac (ERL) with 3.56 GeV positrons from synchrotron storage ring. In this work, we constructed the TAC-PF detector design by using a recently developed framework namely Detector Description for High Energy Physics (DD4hep). The baseline TAC-PF detector design and its qualifications were summarized, followed by a general description.Türk Fizik Derneğ

Light Higgs bosons and muon g-2 in THDM

Bu çalışma, 06-09, Eylül 2016 tarihlerinde Bodrum[Türkiye]’de düzenlenen 32. International Physics Congress of Turkish-Physical-Society (TPS) Kongresi‘nde bildiri olarak sunulmuştur.As well as having a significant impact on models beyond the Standard Model, the Higgs boson discovery has opened a new era in both experimental and phenomenological searches. For instance, observed anomalies in Higgs decays into two photons and four leptons and muon anomalous magnetic moment (muon g - 2) may imply more Higgs-like scalars. In this work, we study Two Higgs Doublet Model-TypeIII, in which one Higgs doublet develops a zero vacuum expectation value. we find the mass spectrum include five Higgs bosons each of which is lighter than about 350 GeV. We consider the contributions to muon g - 2 from these light extra Higgs bosons, and we find that the discrepancy between the SM and the experimental measurements can be resolved if m(H), m(A), m(H perpendicular to) less than or similar to 150 GeV.Türk Fizik Derneğ
