Investigation of the time evolution of Lane-emden-type Kanai-caldirola oscillator
(2009)
In this study, we have investigated the time evolution of the first kind Lane-Emden-type Kanai-Caldirola oscillator. The total energy of the one dimensional classical harmonic oscillator with time-dependent mass is obtained. ...
Phase transitions in a high-chromium and medium-carbon steel
(2008)
Investigation of phase transformations in a high-chromium and medium-carbon steel were carried out with scanning electron microscopy (SEM) and Mössbauer spectroscopy for different prior heat treatment conditions of studied ...
An elastic-plastic stress analysis steel-reinforced thermoplastic composite cantilever beam
(2008)
In the present study an analytical elastic-plastic stress analysis is carried out for a low-density homogeneous polyethylene thermoplastic cantilever beam reinforced by steel fibers. The beam is loaded by a constant single ...
Characterization of martensite in Fe-25%Ni-15%Co-5%Mo alloy
(2009)
Kinetic, morphological, crystallographical, magnetic and thermal characteristics of thermally induced martensite in Fe-25%Ni-15%Co-5%Mo alloy have been investigated by scanning electron microscope (SEM), transmission ...
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 ...
Synthesis of {substituted-[(4-{[4-(carboxymethyl-carbamoyl)phenylimino] methyl}benzylidene)-amino]benzoylamino}carboxylic acids
(2008)
Some novel derivatives of methotrexate like compounds 2a-f have been synthesized, using terephthalaldehyde, isophthalaldehyde, 4-aminobenzoic acid and amino acids (glycine, ?-alanine, L-glutamic acid). The structures of ...
Synthesis of some novel derivatives of 2,6-diaminoanthraquinone dyes
(2008)
In present study, some derivatives of 2,6-diaminoanthraquinone dyes are synthesized and their UV-visible spectra are investigated in various conditions. Ten compounds (1a-e) and (2a-e), two of which (1a, 1b) were previously ...
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 ...
