The Impact of Individual Assumptions on Functional Size Measurement
Turetken, Oktay; Top, Ozden Ozcan; Ozkan, Baris; Demirörs, Onur (2008-11-20)
Having been improved, evolved and standardized by the Organization for Standardization (ISO), Functional Size Measurement (FSM) methods have become widely used. However, the measurers still face difficulties in measuring the software products which include unconventional components. We faced the challenge to observe if different interpretations or assumptions of the measurers cause significant differences in the measurement results. In this study, we present the results of a multiple case study we conducted...
Studies towards the preparation of functionalized cellulose microspheres with affinities towards negatively charged biomembranes
Demirel, Kaan; Türkyılmaz, Serhan; Department of Chemistry (2021-7)
Cellulose microspheres (CMs), generally with diameters in the 10-1000 µm range, have been used as stationary phases in chromatography, substrates for ion exchange applications, supports for protein immobilization and solid-phase synthesis, and drug loading and release materials. Furthermore, cellulose and CMs are biocompatible and have been used in many biomedical applications as varied as the dressing of wounds and blood filtration. Targeting of bacterial cells can be achieved using antibodies, antibody fr...
Effect of layer relaxation on the internal photoemission in Pt/Si1-xGex Schottky barrier type infrared detectors
Aslan, B; Turan, Raşit; Nur, O; Karlsteen, M; Willander, M (1999-12-02)
A Schottky type infrared detector fabricated on a p-type Si1-xGex substrate has a higher cut-off wavelength than one on a pure Si substrate because the barrier height of the Schottky junction on p-type Si1-xGex decreases with the Ge content and the induced strain in the Si1-xGex layer. We have studied the effect of the strain relaxation on the internal photoemission and I-V characteristics of a Pt/Si1-xGex Schottky junction with x=0.14. It is shown that the cut-off wavelength of the diode made on a strained...
The effect of Halobacterium halobium on photoelectrochemical hydrogen production
Sediroglu, V; Yucel, M; Gündüz, Ufuk; Turker, L; Eroğlu, İnci (1997-06-26)
A bio-photoelectrochemical (bio-PEC) reactor containing the photosynthetic bacterium Halobacterium halobium has been constructed. H. halobium contains a retinal protein, bacteriorhodopsin, in its purple membrane that gives protons upon illumination. In this system, the biocatalytic effect of bacteriorhodopsin on photoelectrochemical hydrogen production was determined.
