The Effect of Reinforcement Volume Ratio on Porosity and Thermal Conductivity in Al-Mgo Composites
(Univ Fed Sao Carlos, Dept Engenharia Materials, 2012)
In this study, the effects of reinforcement volume ratios (RVR) on composite structure and thermal conductivity were examined in Al-MgO reinforced metal matrix composites (MMCs) of 5%, 10% and 15% RVR produced by melt ...
Particle swarm optimization for pilot tones design in MIMO-OFDM systems
(Springer, 2011)
Channel estimation is an essential task in MIMO-OFDM systems for coherent demodulation and data detection. Also designing pilot tones that affect the channel estimation performance is an important issue for these systems. ...
Electrochemical determination of iodide by poly(3-aminophenylboronic acid) film electrode at moderately low pH ranges
(Elsevier, 2011)
A new potentiometric sensor for the determination of iodide based on poly(3-aminophenylboronic acid) (PAPBA) film electrode was constructed. Poly(3-Aminophenylboronic acid) films were synthesized electrochemically on ...
Electrochemical polymerization of 2-aminothiazole
(Springer, 2011)
Electrochemical polymerization of 2-aminothiazole (AT) was studied in acetonitrile with tetrabutylammonium tetrafluoroborate (TBAFB) as the supporting electrolyte via constant potential electrolysis (CPE). The redox behavior ...
Cadmium Induced Changes on Growth Performance, Some Biochemical Parameters and Tissue in Broilers: Effects of Vitamin C and Vitamin E
(Academic Journals Inc, 2011)
This study was performed to determine the effects of vitamin C (vit C) and vitamin E (vit E) on growth performance, some biochemical parameters and tissue changes in broiler chickens exposed to cadmium (Cd). One hundred ...
Heavy metal accumulations of Allium cepa L. as a bioindicator for air pollution in Eregli, Turkey
(Academic Journals, 2011)
Eregli, a province with iron-steel industrial activities, is situated on the coast of Black Sea in Northwestern Anatolia. Heavy metal pollution caused by industrial activities is a threat to environmental quality and human ...
Carolina poplar (Populus x canadensis Moench) as a biomonitor of trace elements in Black sea region of Turkey
(Triveni Enterprises, 2010)
In this study, the leaves, bark and the soil supporting Populus x canadensis Moench were tested as a possible biomonitor of trace element pollution in the Middle Black Sea region of Turkey The investigations were carried ...
Back Propagation Neural Network Approach for Channel Estimation in OFDM System
(Ieee, 2010)
In high data rate communication systems which use orthogonal frequency division multiplexing as a modulation scheme, at receiver channel impulse responses must be estimated for coherent demodulation. In this paper, ...
Use of 4-vinylpyridine and 2-hydroxyethylmethacrylate monomer mixture grafted poly(ethylene terephthalate) fibers for removal of congo red from aqueous solution
(Walter De Gruyter Gmbh, 2008)
In this study, a novel fibrous adsorbent made by grafting 4-vinyl pyridine (4-VP) and 2-hydroxyethylmethacrylate (HEMA) monomer mixture onto poly(ethylene terephthalate) (PET) fibers was used for removal of Congo red (CR) ...
Morphological variation and plant nutrients effects of two taxonomically distant Centaurea L. species
(Asian Journal Of Chemistry, 2008)
In this study, the influence of habitat on Centaurea mucronifera and C pyrrohoplephara, whose morphological variants show obvious differences, spreading on calcareous soils of Mediterranean, Central and East Anatolia were ...
