Assessment of the sediment toxicity in Bulgarian and Turkish rivers using the biomarkers in chironomus riparius Mg. (Diptera: Chironomidae)
(2012)
As a model organism we used Chironomus riparius Mg. - a widely distributed species that can be reared in the laboratory conditions and has excellent salivary gland chromosomes. The study showed that the genome at cytogenetical ...
Effects of pretreatment and various operating parameters on permeate flux and quality during ultrafiltration of apple juice
(2012)
The central composite design with a quadratic model was used to investigate the effect of temperature (20-40°C) and transmembrane pressure (TMP) (100-300kPa) as well as pretreatment with gelatin and bentonite (0:0-300:1500mgL ...
Estimation of the Bond grindability index from chemical analysis values and modulus of mixture of raw material of marls
(ICE Publishing Ltd., 2012)
In this study, the relationships between Bond grindability index (G bg) and chemical constituents were investigated on marl samples from the AS cement factory (Burdur/Turkey). First, standard Bond grindability tests were ...
Experimental investigation of impinging jet array heat transfer from a surface with V-shaped and convergent-divergent ribs
(2012)
Detailed heat transfer measurements over a surface with V-shaped ribs (V-SR) and convergent-divergent shaped ribs (CD-SR) by a circular impinging jet array was investigated using thermal infrared camera. Both V-SR and CD-SR ...
Velocity field and turbulence effects on heat transfer characteristics from surfaces with V-shaped ribs
(2012)
The flow field of smooth surfaces and surfaces with V-shaped ribs (V-SR) was studied experimentally with a Laser-Doppler Anemometry (LDA) system. In addition, heat transfer characteristics were experimentally investigated. ...
Nickel-based bimetallic nanocatalysts in high-extent dehydrogenation of hydrazine borane
(2012)
Hydrazine borane N 2H 4BH 3 (HB) is a promising chemical hydrogen storage material but its development is highly dependent on the catalyst that will be used to dehydrogenate it, that is, to hydrolyze the BH 3 group and ...
Irreversibility analysis of a compression refrigeration cycle using natural refrigerants for a sustainable future
(2012)
Irreversibility analyses of R290, R717, R718 and R744 are carried out in a compression refrigeration cycle. The effects of evaporator temperature, condenser temperature and isentropic efficiency on the irreversibility of ...
An artificial neural network model for the effects of chicken manure on ground water
(2012)
In the areas where broiler industry is located, poultry manure from chicken farms could be a major source of ground water pollution, and this may have extensive effects particularly when the farms use nearby ground water ...
Effect of different palatal vault shapes on the dimensional stability of glass fiberreinforced heat-polymerized acrylic resin denture base material
(2012)
Objective: The aim of this study was to determine the effect of different palatal vault shapes on the dimensional stability of a glass fiber reinforced heat polymerized acrylic resin denture base material. Methods: Three ...
Estimation of the bond grindability index from the sink-float test data of two different particulate pumices
(Taylor and Francis, 2012)
In this study, equations for estimating the Bond grindability index by the sink-float test data of pumice were developed. Primarily, the cumulative weight and porosity content of the floating fraction were determined for ...
