The aim of this thesis study is to investigate factors affecting hydrogen (H2) and poly-hydroxybutyrate (PHB) production via photofermentation using two strains of Rhodobacter capsulatus species. To this purpose, three experimental designs were set up, namely Set 1, Set 2 and Set 3. In Set 1, various approaches in pretreatment of bacterial biomass were investigated. For R. capsulatus Wild Type (WT) strain, employment of different pretreatment methods did not make a significant difference, where an average ...
Investigation of cellular responses in a patient with STAT1 gain-of-function mutation successfully transplanted with Ruxolitinib bridge therapy and characterization of anti-viral immune responses in DOCK8 deficiency
Kayaoğlu, Başak; Muyan, Mesut; Department of Biology (2023-1)
Gain-of-function mutations (GOF) in the STAT1 gene are associated with impaired STAT1 phosphorylation/dephosphorylation cycle and Th17 deficiency. A sporadic T835M mutation in the STAT1 gene was detected in a patient with chronic mucocutaneous candidiasis (CMC), viral and bacterial infections accompanied by autoimmunity. Here, we aimed to investigate the cellular level defects in the patient and how they were affected by Ruxolitinib treatment and hematopoietic stem cell transplantation (HSCT). We showed tha...

Analysis of an inventory system with advance emand information and supply uncertainty
Arıkan, Emel; Süral, Haldun; Department of Industrial Engineering (2005)
In this study we address a periodic review capacitated inventory system with supply uncertainty where advance demand information is available. A stochastic dynamic programming formulation is applied with the objective of minimizing the expected inventory related costs over a finite horizon. Three different supply processes are assumed. Under the all-or-nothing type supply process and partially available supply process, the structure of optimal policy is proved to be a base stock policy and numerical example...
Direct synthesis of hydrogen storage alloys from their oxides
Tan, Serdar; Öztürk, Tayfur; Aydınol, Mehmet Kadri; Department of Metallurgical and Materials Engineering (2011)
The aim of this study is the synthesis of hydrogen storage compounds by electrodeoxidation technique which offers an inexpensive and rapid route to synthesize compounds from oxide mixtures. Within the scope of this study, two hydrogen storage compounds, FeTi and Mg2Ni, are aimed to be produced by this technique. In the first part, effect of sintering conditions on synthesis of FeTi was studied. For this purpose, oxide pellets made out of Fe2O3-TiO2 powders were sintered at temperatures between 900 °C – 1300...
