Processing of urea-formaldehyde-based particleboard from hazelnut shell and improvement of its fire and water resistance
(Wiley Blackwell, 2009)The purpose of this study was to manufacture urea-formaldehyde-based particleboard from hazelnut shell and eliminate its disadvantages such as flammability, water absorption, swelling thickness by using fly ash and ... -
Residual stress analysis of aluminum metal matrix composite laminated plates with a square hole
(2009)Metal matrix composites provide new materials with superior properties. They give high strength and stiffness. In this study, a stainless steel reinforced aluminum metal matrix laminated simple supported plate with a square ... -
Reduction of ochratoxin a levels in white wine by yeast treatments
(John Wiley and Sons Inc., 2009)This paper describes the abilities of 21 yeast strains isolated from six different wine-grapes of Turkey to bind ochratoxin A (OTA). Viable (108 CFU/mL) and heat-treated yeast cells were incubated both in phosphate-buffered ... -
An experimental investigation of heat transfer enhancement in a rectangular duct with plate fins
(2009)In this study, using an ideal heat exchanger model, a detailed evaluation of performance parameters in the turbulent regime for the enhancement of heat transfer by using winglet-type vortex generators is carried out. The ... -
Exergy transfer in a porous rectangular channel
(Elsevier Ltd, 2009)Present paper is performed to investigate the heat and exergy transfer characteristics of forced convection flow through a horizontal rectangular channel where open-cell metal foams of different pore densities such as 10, ... -
Sizing problem for a cross flow heat exchanger with wing-type vortex generator
(2009)In the present study, sizing of a single pass cross flow heat exchanger with unmixed fluid streams has been investigated. The heat exchanger is a cross flow heat exchanger. It has overall dimensions of 20 × 20 × 20 cm. Two ... -
River water quality model verification through a GIS based software
(2009)Research and development attempts on water quality models created valuable resources in the sense of model calibration and verification techniques. Recognizing the current degree of pollution in rivers and the importance ... -
Heat transfer augmentation by swirl generators inserted into a tube with constant heat flux
(2009)A novel conical injector type swirl generator (CITSG) is devised in this study. Performances of heat transfer and pressure drop in a pipe with the CITSG are experimentally examined for the CITSGs' angle (α) of 30°, 45° and ... -
The fate of mycotoxins during thermal food processing
(2009)Mycotoxins are considered to be heat-stable molecules. Because of their toxic effects, information about their stability in thermal processes and potential inactivation procedures is needed. Numerous reports in the literature ... -
A parameter identifiability and estimation study in Yesilirmak River
(2009)Water quality models have relatively large number of parameters, which need to be estimated against observed data through a non-trivial task that is associated with substantial difficulties. This work involves a systematic ... -
Effects of probiotic bacteria on the bioaccessibility of aflatoxin B1 and ochratoxin A using an in vitro digestion model under fed conditions
(Taylor and Francis, 2009)In the present study, we aimed at determining the release of aflatoxin B1 (AFB1) and ochratoxin A (OTA) from different food products in the gastro-intestinal tract in the absence and presence of probiotics, a possible ... -
Ochratoxin A in cereal-derived products in Turkey: Occurrence and exposure assessment
(Elsevier, 2009)Eighty-three samples of cereal-derived products including 24 breakfast cereals, 24 cereal-based baby foods and 35 beers purchased from supermarkets and small shops of Adana in Turkey were analysed for the presence of ... -
Prevention and management of mycotoxins in food and feed
(Springer Berlin Heidelberg, 2010)The contamination of food and animal feeds with mycotoxins is a worldwide problem, while mycotoxins occur more frequently under tropical conditions as a result of environmental conditions in the field coupled with improper ... -
Pore modification in porous ceramic membranes with sol-gel process and determination of gas permeability and selectivity
(2010)Summary: The aim of the study was to investigate the variation in total surface area, porosity, pore size, Knudsen and surface diffusion coefficients, gas permeability and selectivity before and after the application of ... -
