A parasitic layer-based reconfigurable antenna design by multi-objective optimization
(2012)
A parasitic layer-based multifunctional reconfigurable antenna (MRA) design based on multi-objective genetic algorithm optimization used in conjunction with full-wave EM analysis is presented. The MRA is capable of steering ...
A case study: Assessment of preservice secondary mathematics teachers' metacognitive behaviour in the problem-solving process
(2010)
The purpose of the present study was to investigate preservice secondary mathematics teachers' metacognitive behaviour in the mathematical problemsolving process. The case study methodology was employed with six preservice ...
The views of primary school students on use of riddles in the process of education and training
(2012)
The purpose of this research was to determine the primary school students' views on the use of riddles in the process of education and training. This research was conducted with descriptive survey. 192 primary school ...
The relationship between the carrying angle and the distal extent of the 2nd and 4th fingertips
(2012)
The angle towards the lateral side between the arm and forearm when the forearm is in full extension and supination is defined as the carrying angle. It is well known that the 2nd finger is longer in women whereas the 4th ...
Vibration analysis of asymmetric shear wall - Frame structures using the transfer matrix method
(2012)
Vibration analysis plays an important role in the structural design of tall buildings. In this study, a vibration analysis of asymmetric shear wall-frame structures is carried out by a transfer matrix method. The method ...
Cloud point extraction and spectrophotometric determination of mercury species at trace levels in environmental samples
(2012)
A new micelle-mediated separation and preconcentration method was developed for ultra-trace quantities of mercury ions prior to spectrophotometric determination. The method is based on cloud point extraction (CPE) of Hg(II) ...
Micelle-Mediated Extraction and Flame Atomic Absorption Spectrometric Method for Determination of Trace Cobalt Ions in Beverage Samples
(2012)
A new method has been developed for preconcentration of cobalt at trace levels in beverage samples using calcon carboxylic acid as chelating agent and cetyl pyridinium chloride as an auxiliary ligand and entrapped into ...
Acute demyelinating encephalomyelitis presenting with a mass lesion
(2011)
Acute disseminated encephalomyelitis (ADEM) is usually a monophasic disease that may follow many infections or vaccines. Neuroimaging plays a key role in the differential diagnosis of ADEM. We reported a female patient ...
Association of different uncus lesions on magnetic resonance imaging with epilepsy
(2016)
Objective: Uncus is the hook-like most anteromedial portion of the parahippocampal gyrus and is a part of the limbic system. It is the only gyrus, together with the amygdala, that contains nuclei and is associated with ...
Can laser welding stop corrosion of new generation magnetic attachment systems?
(2011)
Rare earth magnets have been used in both prosthodontics and orthodontics, but their corrosion tendency in the oral cavity limits long term clinical application. The purpose of this study was to evaluate corrosion of new ...
