  • Optimal resilient retrofit design of heat-exchanger networks 
    Konukman, Alp Er Şevki. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 1996., 1996.)
    A new index, called Design Resiliency Index, which numerically indicates the size of feasible region in terms of uncertain source-temperature or flowrates for the fixed design parameters of a network structure, is proposed. ...
  • Peptide drugs against antibiotic resistant bacteria 
    Alaybeyoğlu, Begüm. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2017., 2017.)
    Membrane active peptides have found great interest as drug candidates due to their unique mode of action and availability in nature. In the past 20 years, beta lactamase-mediated antibiotic resistance has become a lethal ...
  • pH and temperature dependence of the rate of dissolution of AgIO3 
    Uyanık, Ömer Lütfi. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 1984., 1984.)
    In this thesis a theory based ona dissolution model was checked experimentally. The theory which is developed by B.V. Enüstün expresses the initial rate of dissolution for a 1:1 type ionic solid in terms of the model ...
  • Photocatalytic hydrogen production over ionic liquid coated semiconductors 
    Can, Elif. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2021., 2021.)
    The objective of this thesis is to develop active and stable dye sensitized and ionic liquid (IL) encapsulated photocatalysts for hydrogen production, and to investigate the roles of photocatalysts constituents on hydrogen ...
  • Production of Taq I restriction and modification enzymes by using two different expression systems 
    Toksoy, Ebru. (Thesis (Ph.D)- Bogazici University. Institute for Graduate Studies in Science and Engineering, 2000, 2000.)
    Taq I restriction-modification system has been cloned and expressed using two different expression systems. In the first system, Taq I restriction endonuclease was expressed as a fusion protein with the maltose-binding ...
  • Recognition and binding processes in HIV-1 protease 
    Özer, Asuman Nevra. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2008., 2008.)
    HIV-1 protease is a drug target against AIDS and understanding its molecu- lar recognition processes is important in development of drugs. Here, the combined computational methodologies used put three different perspectives ...
  • Segmental orientation and conformational dynamics of polymer chains 
    Haliloğlu, Türkan. (Thesis (Ph.D)- Bogazici University. Institute for Graduate Studies in Science and Engineering, 1992., 1992.)
    Various remarkable features of polymers, as compared with metallic and inorganic materials, arise from the fact that macromolecules can take up various conformations. The study of macromolecular conformations and dynamics ...
  • Stoichiometric models in metabolic systems biology of yeast 
    Çakır, Tunahan. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2006., 2006.)
    A system-level analysis of Saccharomyces cerevisiae metabolism was performed through integration of stoichiometric modeling and high-throughput ‘omics’ data. A bridge between metabolic networks and transcriptomics was built ...
  • Supercritical carbon dioxide immobilization of glucose oxidase on conducting polymers towards biosensor production 
    Talay, Defne Kayrak. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
    In this work, glucose oxidase (GOX) is immobilized on conducting polymer matrices (polypyrrole film, PPY; polyurethane/polpyrrole composite foam and film, PU/PPY) via Supercritical Fluid Immobilization (SFI) for further ...
  • System biology of yeast signal transduction 
    Arğa, Kazım Yalçın. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2007., 2007.)
    Reconstruction of protein interaction networks that represent groups of proteins contributing to the same cellular function is a key step towards quantitative studies of signal transduction pathways. In the present study, ...
  • Systems-level understanding of copper effect in Saccharomyces cerevisiae 
    Öç, Şebnem. (Thesis (Ph.D.) - Bogazici University. Institute for Graduate Studies in Science and Engineering, 2019., 2019.)
    Copper is a crucial trace element for all living systems as it is required for the proper functioning of several biological processes. Copper homeostasis, which governs the mechanisms of copper uptake, delivery, utilization, ...
  • Utilization of carbon dioxide and methane via catalytic reforming reactions 
    Aydınoğlu, Şeyma Özkara. (Thesis (Ph.D.)-Bogazici University. Institute for Graduate Studies in Science and Engineering, 2008., 2008.)
    The overall purpose of this research study was to investigate new catalysts to produce synthesis gas via CO2 reforming of methane under optimized reaction conditions. The thesis consists of four parts. In the first part ...
