Tuz Gölü'nün suyu, derin bölgede daha seyrellik olmak üzere Na-Cl îipi salamura sınıfına girmektedir. İyon konsantrasyonları çökelmekte olan halit, jips, aragonit ve kalsit minerallerinin değişikliğe uğrattığı evaporasyona bağlı evrim eğilimleri sergilemektedirler. Ana göl bölgesinde çökeller esas olarak jips, hantit, manyezit ve polihalit minerallerinden oluşmaktadır. Derin bölgede ise, çökel mineralleri Mg-kalsit ve dolomittir. Gölden elde edilen veriler ile yapılan termodinamik doygunluk hesaplan; iyonlar-arası etkileşim ve iyon-birlikteliği forınüJasyonlanm esas alan modellerin doğada gözlemlenen evaporit "minerallerinin çökelimini veya çözünümünü tespitte kullanılabileceğini göstermiştir. İyonik gücü molal ölçekte 1.35 den 8.5 a kadar değişen Tuz Gölü'nün sularında her iki modelin doygunluk hesaplama kapasiteleri benzer bulunmuştur. Bunlara ek olarak, söz konusu modellerin güncel çökeller ışığında daha önce çökelmiş minerallerin kökenlerini incelemede yararlı olabilecekleri gösterilmiştir.

Effect of alkalinity on flotation behavior of quartz Sayılgan, Aslı Halime; Arol, Ali İhsan; Department of Mining Engineering (2003) Carbonates are always present in natural waters, thus in the process waters in flotation. When CO2 dissolves in water it forms a weak acid. This acid and its salts in solution constitutes the carbonic system. The pH of natural waters on land is controlled mainly by this system. Alkalinity is the capacity of a water to neutralize strong acids. In natural waters, this capacity is attributable to bases such as HCO3, CO3" and OH" as well as to species often present in small concentrations such as silicates, bor...
Effect of hydrodynamics on the production of pickering emulsions in unbaffled stirred tanks Demirdoğan, Özge; Ayrancı Tansık, İnci; Department of Chemical Engineering (2019) An emulsion is a fluid system obtained by dispersing one of two immiscible liquids in the other. Since this formation is thermodynamically unstable, it has to be stabilized using an emulsifier. Emulsions in which solid particles are used as emulsifiers are called Pickering emulsions. In this study, the investigation of the effect of different hydrodynamic conditions on the production of Pickering emulsions in unbaffled stirred tanks was aimed. Oil in water Pickering emulsions were produced. Distilled water ...
Biochemical and genetic studies on the pyruvate branch point enzymes of rhizopus oryzae Açar, Şeyda; Hamamcı, Haluk; Department of Biotechnology (2004) Rhizopus oryzae is a filamentous fungi which produces lactic acid and ethanol in fermentations. R. oryzae has numerous advantages for use industrial production of L-(+)-lactic acid but the yield of lactic acid produced on the basis of carbon consumed is low. Metabolic flux analysis of R. oryzae has shown that most of the pyruvate produced at the end of the glycolysis is channelled to ethanol, acetyl-CoA and oxaloacetate production. This study aimed to answer some questions addressed on the regulation of pyr...
Cleaning of Şırnak Karatepe asphaltites Demir, Emre; Atalay, M Ümit; Department of Mining Engineering (2009) Asphaltite is petroleum originated substance and formed by metamorphism. Turkey has 82 million tons of asphaltite reserves in Sırnak and Silopi region of Southeastern part of Anatolia. The proximate analysis of Sırnak Karatepe asphaltite sample indicated that the ash and sulfur content were 46.86 % and 5.56 %, respectively. In this study, Sırnak Karatepe asphaltite sample was concentrated by gravity separation and flotation methods. The aim of this research was to decrease the ash and sulfur content below 2...
Screening of the putative hexokinase genes from rhizopus oryzae Alagöz, Eda; Hamamcı, Haluk; Yücel, Ayşe Meral; Department of Biotechnology (2013) Rhizopus oryzae is a filamentous fungus which can ferment sugar to ethanol, and lactic acid. Increasing demand of the world for use of renewable carbon sources has put this and similar organisms into a position where the biotechnology industries are more and more interested with these organisms. R. oryzae can grow on some renewable carbon sources which makes it a good candidate for production of ethanol as well as lactic acid. The major use of lactic acid is in food industry and food- related application, w...
