In this study the effects of bond-coatings on various calcium phosphate coatings were studied. From human teeth dentine (DFA) and enamel derived fluorapatite (EFA) plasma powders were sprayed on titanium with and without a bond-coating. As control group original hydroxyapatite (HA) powder for biomedical spraying purposes was also used on titanium with and without a bond-coating. Tensile strength tests were performed according to the F-633 ASTM standards. It was observed that bond-coatings had significantly increased the tensile strength values compared to non-bond coatings. It was interesting that the use of a bond-coating did not influence any remarkable tensile strength values compared to original coating values but that the % of micro voids has decreased from 1.11% to 0.29%. This means that a better plasma coating with less micro voids, which could affect the quality of the coating with continuous progress, has been provided. In other words, the use of bond-coatings was found to be very useful. This phenomenon should be investigated in further studies to develop better implant coats.

Effects of spray drying temperature and additives on the stability of serine alkaline protease powders Namaldi, Aysegul; Çalık, Pınar; Uludağ, Yusuf (2006-01-01) In this study, after production by recombinant Bacillus subtilis (BGSC-1A751), carrying pHV1431:: subc gene in the complex medium and separation of solids from the fermentation broth, serine alkaline protease (SAP) was dried in order to investigate the stabilization during spray drying and subsequent storage. The effect of air inlet temperature of the spray dryer between T = 70 and 130 degrees C and the effect of protective additives, glucose and maltodextrin, at 0-2% (w/v) on SAP activity during spray dryi...
Effect of Polymers on the Rheological Properties of KCl Polymer Type Drilling Fluid Kök, Mustafa Verşan (2005-05-01) In the course of this research, the effect of two polymers (xanthan gum and polyanionic cellulose) on the rheological properties of KCl/polymer type drilling fluids was investigated. Non-Newtonian drilling fluids are conventionally characterized by rheological models (Bingham Plastic, Power Law, Casson, Herchel-Bulkley and Robertson-Stiff). In this research, forty-five KCl/polymer data sets of varying compositions are prepared. Polymer addition to the system has affected the model and caused a variation of ...
Effects of bioreactor operation parameters on intracellular reaction rate distribution in beta-lactamase production by bacillus species Arifoğlu, Müge; Çalık, Pınar; Department of Chemical Engineering (2004) In this study, the effects of oxygen transfer (OT) on beta-lactamase production and on intracellular reaction rates were investigated with Bacillus licheniformis ATCC 2597. In order to clarify the oxygen transfer effects on the production of beta-lactamase, firstly a glucose based defined medium was designed and using this medium, the effects of bioreactor operation parameters, i.e., pH and temperature, on beta-lactamase activity and cell formation were investigated in laboratory scale batch-bioreactors usi...
Effect of extrusion on the functional properties of carrot pulp added extrudates and in-vitro bioaccessibility of lutein and beta-carotene Ortak, Melda; Şensoy, İlkay; Ögel, Zümrüt Begüm; Department of Food Engineering (2014) In this study, effects of extrusion on the functional properties of carrot pulp added extrudates was investigated. Extrusion was performed at four different conditions. Two different temperature profile and two different screw speeds were investigated. Change in antioxidant activity, phenolic content, β-carotene and lutein content and their in-vitro bioaccessibilities after extrusion were investigated. Antioxidant activity and total phenolic content was determined by DPPH and Folin–Ciocalteu method, respect...
Effects of heavy metals on activated sludge process Dilek, Filiz Bengü; Yetiş, Ülkü (1992-01-01) The purpose of this study was to evaluate the toxic effects nf various heavy metals on activated sludge process. Different concentrations of Cu(II) (0.5, 1.0, 5.0, and 10.0 mg/l), Ni(II) (5.0, 10.0, 25.0 mg/l), and Cr(VI) (1.0, 5.0, 10.0, 25.0, 50.0 mg/l) were maintained in a laboratory-scale completely mixed activated sludge unit, without recycle, treating simulated wastewater. The feed solution contained 650 mg/l protein (corresponding to 1300 mg/l COD) as a source nf carbon. Experimental results indicate...
