Chlorination of poly(3-hydroxy alkanoates) containing unsaturated side chains

Arkın, Ali Hakan | Hazer, Baki | Borcaklı, Mehlika

Unsaturated biopolyesters, (PHA-DB), obtained from pure anchovy (hamci), hazelnut, soybean oily acids and the mixtures of octanoic acid (in weight ratios of 50/50 and 70/30) were chlorinated up to 54 wt % Cl content. The molecular weights (MW) of the chlorinated biopolyesters were between 1.3×104 and 3.0×104 and decreased with the increase in chlorine content in PHA-DB. Melting transitions of the chlorinated biopolyesters were between 62 and 125 °C depending on the chlorine content when compared with those of the original PHAs, 44-55 °C.

Manufacturing and testing of a V-type Stirling engine

Karabulut H. | Yücesu H.S. | Koca A.

An air charged V-type Stirling engine, having 260 cm3 swept volume, was manufactured and tested. Speed-torque characteristics of the engine were obtained for different temperature and charge pressure values in the range of 600°C to 1100°C and 1 to 4 bars. The experiments intended to determine the performance characteristics of the engine at different set up values of pressure and hot source temperature. Maximum output power was obtained at 1100°C and 2.5 bars charge pressure as 65 W. The results are presented in diagrams.

Molecular dynamics simulations of super heated Ni4 cluster

Güven M.H.

The fragmentation mechanism of the super heated Ni4 cluster is studied by employing the microcanonical molecular dynamics simulations and an empirical model potential. Ni4 cluster is heated up above the bulk Ni evaporation point temperature and then classical trajectory analysis as well as RRK theory are used to calculate survival probability, evaporation rate, average kinetic energy release and dissociation energy.

Effect of ceramic particle size and applied pressure on time to complete infiltration of liquid aluminium into SiC powder compacts

Candan E. | Atkinson H.V. | Jones H.

Monitoring of pressurized advance of liquid aluminium into SiC particle compacts of mean particle sizes 12.8, 22.8 and 36.7 µm was carried out under applied pressures of 400 to 900 kPa. Infiltration time of liquid aluminium in the compact was recorded by computer logging the output from pairs of open ended wires with a potential difference between them. Results showed that time necessary to complete infiltration in the compacts decreased with increasing particle size and increasing applied pressure. Experimental results are in reasonably good agreement with model predictions. © 2000 Kluwer Aca ...Daha fazlası

Measurements of localised flux density and power loss under PWM excitation in a typical stator core

Tutkun N. | Moses A.J.

Radial, tangential and resultant flux densities and power loss in a typical stator core from a non oriented non silicon electrical steel were studied at five different locations behind teeth and slots. Results show that the pulse width modulated (PWM) flux density is almost similar with sinusoidal one.

Kinetics of formation, dissociation and equilibrium constants of pentacyanoaquoruthenate(II) with heterocycles

Baran Y.

The kinetics of formation and dissociation reactions of [Ru(CN)5L]3- with a series of heterocyclic ligands were studied in aqueous media. In this presence of an excess of heterocycle, the observed second order rate constants were calculated from the kobs versus [ligand] plot at µ = 0.100 M NaClO4. Activation parameters for the formation reactions (?H‡ = 28 ± 7 kJ mol-1 and ?S‡ = 140 ± 35 J K-1 mol-1) are comparable for all systems, indicating a common mechanism. The kinetics of exchange of coordinated heterocycles for 1,3,5-triazine yielded a rate saturation typical of a limiting dissociative ...Daha fazlası

Yongalevha endüstrisinde bir yöneylem araştırması uygulaması

Karayılmazlar, Selman | Balaban, Erdal

In this study, a model was used for the optimization of product mix (the amounts of each product in the mixture) in particleboard industry by using linear programming. A theoretical model was constructed in which operations research methods and linear programming were applied to the maximization of the profit of a particleboard mill (KÖYKOBİR) as the consumer of industrial wood. To this end, 1993-1994-1995-1996 production, sales, stock quantities and costs as well as data related to capacities of the chipping, drying, pressing, sanding and gluing units were processed. Moreover, processing ...Daha fazlası
