The carboxymethylcellulose-gelatine carrier system was investigated for invertase immobilization. Chromium (III) acetate, chromium (III) sulphate and potassium chromium (III) sulphate were used as cross-linking agents. Effect of carboxymethylcellulose-gelatine ratio and cross-linker concentration on immobilized enzyme activity were analysed. Reusability of immobilized enzyme was also investigated. Maximum immobilized enzyme activities were obtained with cross-linkers chromium (III) sulphate (0.004 mol dm(-3)) and potassium chromium (III) sulphate (0.001 mol dm(-3)) for a carrier composition of carboxymethylcellulose-gelatine ratio 0.111 (w/w) as 78%.

A novel cyclodextrin homodimer with dual-mode substrate binding and esterase activity Tastan, P; Akkaya, EU (2000-06-20) A novel cyclodextrin homodimer with two beta-cyclodextrin units tethered from the primary side by a tris(2-aminoethyl)amine linker was found to be hydrolytically active. The hydrolysis of a ditopic activated carbonate ester was accelerated 150-fold and a Lineweaver-Burk plot showed a biphasic curve indicative of two different binding modes for the activated carbonate ester.
Detection of Unauthorized Photo-Voltaic System Connection for Low Voltage Grids Pouraltafi-Kheljan, Soheil; Göl, Murat (2020-01-01) Vast and unauthorized penetration of the photovoltaic systems in distribution systems imposed inadequate monitoring challenge to system operators. Although the installation of required monitoring infrastructure does seem as a solution, due to the high installation cost, it is not considered a feasible one, at least for the near future. As an alternative approach, a two-stage method composed of an ANN-based mapping function, and a regression model is presented to detect unauthorized PV connections to the sys...
Biodegradation of aldicarb in a packed-bed reactor by immobilized Methylosinus Kok, FN; Arica, MY; Halicigil, C; Alaeddinoglu, G; Hasırcı, Vasıf Nejat (1999-04-01) Carboxymethylcellulose microspheres cross-linked via aluminum ions were used as a support material for immobilization of Methylosinus isolated from soil contaminated with aldicarb. The degradation capacity of immobilized bacteria, different parameters such as substrate concentration (50-800 ppm), flow rate (10-60 ml h(-1)), and continuous contact with reaction medium (flow rate, 20 mi h(-1) and concentration, 100 ppm) that affect aldicarb degradation were investigated in a packed-bed reactor. Increases in t...
Impact of Defected Ground Structures on the Bandwidth of Branch Line Hybrids Polater, Ahmet Mert; Nesimoglu, Tayfun (2015-12-02) This paper investigates the impact of defected ground structures (DGS) on the operational bandwidth of microwave circuits. Branch line hybrids were selected to investigate DGS. Three types of branch line hybrids were studied with both hardware and simulation results; a standard branch line hybrid, one using tapered lines and another one using DGS. An optimum model in terms of location, size and number of DGS has been proposed to achieve the widest operational bandwidth. Not only by simulation results, but a...
Simulation of Rapidly Maneuvering Airfoils with Synthetic Jet Actuators Jee, SolKeun; Lopez Mejia, Omar D.; Moser, Robert D.; Muse, Jonathan A.; Kutay, Ali Türker; Calise, Anthony J. (American Institute of Aeronautics and Astronautics (AIAA), 2013-08-01) Synthetic jet actuators are investigated for rapidly maneuvering airfoils that are regulated by a closed-loop control system. To support active flow-control simulations performed here, the closed-loop system and vehicle dynamics are coupled with computational fluid dynamics. High-frequency sinusoidal pitching simulations with and without synthetic jet actuation indicate that the current synthetic jet actuators provide bidirectional change in aerodynamic forces during rapid maneuvers whose time scales are of...
