Bioprocess design parameters for beta-lactamase production by Bacillus species
Çelik, Eda; Çalık, Pınar; Department of Chemical Engineering (2003)
In this study, the effects of bioprocess design parameters on β-lactamase production were systematically investigated using wild type Bacillus species. For this purpose, the research programme was carried out in mainly four parts. Initially, potential β-lactamase producers were screened and Bacillus licheniformis ATCC 25972, a constitutive β-lactamase producer, was selected. Next, the effects of bioprocess medium components, i.e., carbon sources (glucose, fructose, sucrose, citric acid and glycerol), inorga...
Preparation and characterization of organoclay-polypropylene nanocomposites with maleic anhydride grafted polypropylene compatibilizer
Yılmaz, Şule Seda; Yılmazer, Ülkü; Department of Chemical Engineering (2011)
The aim of this study was to improve the mechanical properties “Moplen” EP300L which is a heterophase copolymer. Polymer blends and nanocomposites were prepared by melt compounding method in a twin screw extruder. Nanofil® 5 (N5) and Nanofil® 8(N8) were used as the organoclays, and maleic anhydride grafted polypropylene (M) was used as the compatibilizer. The effects of additive concentrations and types of organoclays on the morphology, mechanical and thermal properties were investigated. Organoclay loading...
Two channel adaptive speech enhancement
Zaim, Erman; Çiloğlu, Tolga; Department of Electrical and Electronics Engineering (2014)
In this thesis, speech enhancement problem is studied and a speech enhancement system is implemented on TMS320C5505 fixed point DSP. Speech degradation due to the signal leakage into the reference microphone and uncorrelated signals between microphones are studied. Limitations of fixed point implementations are examined. Theoretical complexities of weight adaptation algorithms are examined. Moreover, differences between theoretical and practical complexities of weight adaptation algorithms due to the select...

Synthesis of Phenanthroline-Functionalized Phosphazene Based Metallosupramolecular Polymers and Their Stimuli-Responsive Properties
SEÇKİN, TURGAY; Sezer, Selda; KÖYTEPE, SÜLEYMAN (2018-11-01)
A series of phenanthroline-functionalized phosphazene based metallo-supramolecular polymers (PFP-MSP) was synthesised using a two-step reaction strategy. In first step, three phenanthroline unit containing monomer (PFP-M) was prepared from 5,6-dihydroxy-1,10-phenanthroline and hexachlorocyclotriphosphazene by condensation reaction. Then, this PFP-M was reacted with different metal ion salts (Co, Ni, Cu, Fe, Eu, La, Tb, Lu ions) and resulting for the metallo-supramolecular polymers bearing phosphazene struct...
