Kaparideki fenolik bileşenlerin özütlenmeside yeni bir yöntem: mikrodalga ile özütleme

Kaparideki Fenolik Bileşenlerinmikrodalga İle Özütlenmesi Şümnü, Servet Gülüm(2010-12-31) KAPSAM Çalışmada kapari bitkisinin (tomurcuk kısmı kullanılacaktır. mikrodalganın gücü (50 ve 100%), özütleme süresi (üç farklı zaman ön deneylerle belirlenecektir), katı madde-çözgen oranı (1:10, 1:20, 1:30) ve çözücünün çeşidi (su, etanol ve %50 etanol-%50 su karışımı) olarak belirlenmiştir. Bu değişkenlerin elde edilen özütlerin toplam fenolik madde miktarı ve fenolik bileşenlerin konsantrasyonlarına ve antioksidan kapasitesine olan etkileri incelenecektir. Kontrol olarak konvansiyonel Sokselet özütleme...
Microwave extraction of phenolic compounds from caper and oleaster Durmaz, Ezgi; Şümnü, Servet Gülüm; Şahin, Serpil; Department of Food Engineering (2012) The main objective of this study was to extract phenolic compounds from caper and oleaster by using microwave. The effects of microwave power (400 and 700 W), extraction time (5-20 min), solid to solvent ratio (1:10, 1:20 and 1:30) and solvent type (water, ethanol and different ratios of ethanol-water mixture) on total phenolic content, antioxidant activity and concentration of the phenolic compounds in the extracts were investigated. In conventional extraction, extraction time and solvent type were used as...
Differential gene expression analysis in drug resistant multiple myeloma cell lines Mutlu, Pelin; Gündüz, Ufuk; Department of Biology (2009) The emergence of drug-resistance of tumor cells is a major complication for succesful chemotherapy. In this study, the molecular mechanisms of resistance to prednisone, vincristine and melphalan in multiple myeloma cell lines, RPMI-8226 and U-266 were investigated. Drug resistance was induced by application of the drugs by stepwise dose increments and confirmed by XTT cytotoxicity assay. Gene expression analysis demostrated that MDR1 gene is one of the most important factor causing the multidrug resistance ...
Generalization of the law of the wall. Köken, Mete; Tokyay, Nuray; Department of Civil Engineering (2002) In this study the classical law of the wall, which is obtained for the flat plate, is generalized such that it will hold true for the turbulent axisymmetrical flow as well. A turbulent boundary layer on a transversly curved surface has a different structure from that of a flat plate boundary layer. This transverse curvature effect is of importance in computations of the boundary layer near the tail of a body of revolution^ in estimating the surface resistance of ship models, or other three- dimensional elon...
125 PS LSB Column Parallel Time To Digital Converter integrated Circuit For Lidar Applications Özpınar, Oğuzhan; Akın, Tayfun; Department of Electrical and Electronics Engineering (2021-2-04) This thesis presents acolumn-parallel time to digital converter (TDC) integrated circuit for light detection and ranging (LIDAR)systems. The designis based on direct time-of-flight (dToF) measurement. It is designed to be used with single-photon-avalanche photodiodes (SPAD)arrays. The TDC can measure the time differences up to 1μs with 125ps precision.This TDC design consistsof four main blocks. Acounter, a phase-locked loop (PLL), a delay-locked loop (DLL), and a tapped ...
