Energy and irreversibility analysis of a cascade refrigeration system for various refrigerant couples
(2010)
This study deals with energy and irreversibility analysis of a cascade refrigeration system employing various refrigerant couples, namely R152a–R23, R290–R23, R507–R23, R234a–R23, R717–R23 and R404a–R23, using a computer ...
Computer controlled test system for measuring the parameters of the real thermoelectric module
(Elsevier Ltd, 2011)
Different methods have been developed for measuring the performances of thermoelectric (TE) modules. However, the foundation of these methods accepts the parameters of semiconductors as constant and foresees temperature ...
Seasonal succession of the phytoplankton community and evaluation of water quality using trophic diatom index in a stream
(Scibulcom Ltd., 2016)
Phytoplankton species composition, seasonal variation and the factors effecting the variation were studied in this study one-year period, from June 2010 to May 2011. Water samples were collected monthly from four stations. ...
Seasonal distribution of epipelic diatom assemblages and relations to environmental variables in a mesotrophic pond
(Scibulcom Ltd., 2016)
The seasonal succession of diatom species in the epipelon of shallow, mesotrophic pond OMU Pond I (Turkey) with special attention to diatoms (particularly Navicula) is described. The composition of epipelic algal assemblages ...
Fe(II)-Co(II) double salt incorporated magnetic hydrophobic microparticles for invertase adsorption
(Humana Press Inc., 2015)
Invertase (β-fructofuranoside fructohydrolase, EC 3.2.1.26) is an enzyme widely used in the food industry. Its main function is the formation of glucose and fructose through hydrolysis of sucrose. For the separation and ...
Magneto-optical investigation and hyperfine interactions of copper substituted Fe3O4 nanoparticles
(Elsevier Ltd, 2016)
CCopper substituted Fe3O4 nanoparticles (NPs) (CuxFe1−xFe2O4 (0.0≤x≤1.0)) were synthesized by polyol method and the effect of Cu2+ substitution on structural, magnetic and optical properties of Fe3O4 was investigated. X-ray ...
Dielectric properties, cationic distribution calculation and hyperfine interactions of La3+ and Bi3+ doped strontium hexaferrites
(Elsevier Ltd, 2016)
La3+ and Bi3+ doped M-type strontium hexaferrites (SrM) were prepared by sol–gel-auto combustion. X-ray powder diffraction (XRD), Scanning Electron Microscopy (SEM), Vibrating Simple Magnetometer (VSM), Mössbauer Spectroscopy ...
Assessment of endothelial dysfunction with adhesion molecules in patients with celiac disease
(Lippincott Williams and Wilkins, 2016)
Objectives: Celiac disease (CD) is a systemic immune disorder. We assessed serum levels of adhesion molecules as a marker of endothelial dysfunction in patients with CD at first diagnosis and in those on a glutenfree diet. ...
Characterization and photocatalytic properties of nanoporous titanium dioxide layer fabricated on pure titanium substrates by the anodic oxidation process
(Elsevier Ltd, 2014)
Nanoporous titanium oxide (TiO2) layers were fabricated on commercially pure titanium (Cp-Ti) substrates by the anodic oxidation method under a potentiostatic regime. Anodic oxidation was performed in an aqueous solution ...
Structural, morphological, optical, cation distribution and Mössbauer analysis of Bi3+ substituted strontium hexaferrite
(Elsevier Ltd, 2016)
Single-phase M-type hexagonal ferrites, SrBixFe12−xO19 (0.0≤x≤1.0), were prepared by a co-precipitation assisted ceramic route. The influence of the Bi3+ substitution on the crystallization of ferrite phase has been examined ...
