Tarihi 13. yüzyıla dayanan Hz. Ali cenknâmeleri Türk halk edebiyatının önemli kaynaklarından biridir. edebiyatına Arap ve Fars edebiyatından geçmiştir. Özellikle İranlılar tarafından yazılan hakkındaki hikâyeler zamanla yaygınlaşmış epeyce beğenilmiştir. Cenknâme benzeri eserler Hayber Kalesi'nin fethinden sonra yazılmaya başlanmış bir gelenek halinde yüzyıllarca devam etmiştir. Türklerin cenkn...
Background and purpose: Ïn recent years, different studies have been performed regarding the influence of magnetic field on the immune system. There are many contraversies about the effects of different frequencies and amplitudes on the immune system. Materials and methods : Ïn this experimental study, the effects of different frequencies of magnetic field (0,5,50,500 and 5000 Hz) have bee...
objective: in electrochemotherapy (ect), there is an unpleasant sensation of muscle contraction when using a low frequency (1 hz). therefore, by increasing the pulse frequency above the tetanic frequency this painful sensation can be reduced. the aim of the present study is to compare the treatment efficiencies of low and high frequency ect, and estimate the effect of its repeated sessions. mat...
the aim of this investigation is to compare the effect of applying two transcutaneous electrical nerve stimulation (tens) current with different frequencies (2 hz & 100 hz) on hoffmann reflex recorded from gastrosoleus muscle of healthy people. forty female subjects between 20 to 30 years of age were participated in this quasi-experimental design. twenty of them were exposed to the 100 hz curre...
background: the extremely low-frequency electromagnetic field (elf-emf), mainly emitted by electric transmission lines and household electronic appliances, is becoming a worldwide health risk. it is imperative to investigate the biological impacts of elf-emf and to identify products that are resistant to the radiation from 50 hz elf-emf. in this study, we investigated the biological impacts of ...
Modulation transfer functions (MTFs) were measured with three different psychoacoustical paradigms in the same normal-hearing subjects. In the temporal-probe method, the threshold of a 4-ms probe tone (frequencies of 1000 and 4000 Hz) was measured at various envelope phases within a 100% sinusoidally amplitude-modulated (SAM) noise at modulation frequencies from 2 to 256 Hz. For the derived-MTF...
