With the rapid development of technology and the importance of electronic devices in our lives, electromagnetic waves produced by various sources and the related electromagnetic pollution concepts have become an important issue that directly affects the nature…

Elektromanyetik alanların canlılar üzerindeki zararlı etkileri bugün için bilimsel çevreler tarafından en çok üzerinde durulan ve araştırmalar yapılan konulardan biridir. Elektrik enerjisi ile çalışan cihaz ve sistemler çevresine elektromanyetik enerji yaymakt…

Along with development of electronics and software technology, amount of electromagnetic (EM) radiation, which expose to people, has significantly risen. For people who uses or do not use technology, it is of great importance that they should have enough inf…

Cellular phones are playing an important role in technological devices in today’s world. People start to use cellular phones at early ages. Even kids have their own cellular phones as a precaution for their security. However, researches evaluating long term …

Taşıtların elektrik ihtiyacı taşıtın cinsine göre her geçen gün artarak devam etmektedir. Bu ihtiyacı karşılamak taşıtlarda bulunan geleneksel elektrik üretim ve depolama yöntemi dışında egzoz ısının geri kazanımı, güneş enerjisi uygulamaları yanı sıra süspa…

Maxwell denkleminin AV formülasyonu esas alınarak, zamana bağlı bir akım altında süperiletken telin elektromanyetik özelliklerini çözmek için yeni bir sayısal model geliştirilmiştir. Farklı akım genlikleri için alternatif akım (AA) kayıpları hesaplanmış ve iki…

One of the significant factors that should be examined when performing a thermoluminescence (TL) study related to a natural material is the detection of the trap depth. The various heating rate (VHR) method is one of the practical methods used in the calculati…

Bu çalışmada trafo merkezi ve yüksek gerilim hatları etrafında halkın maruz kaldığı manyetik alan seviyelerinin belirlenmesi amacıyla Konya’da manyetik akı yoğunluğu değerleri ölçülmüştür. Ölçümler yüksek gerilim hattı ve trafo merkezine farklı uzaklıklarda …

The devices developed in the field of organic electronics in recent years are on the technological applications and development of organic electronic devices using organic semiconductor films. The main applications of the organic electronic revolution are; Ele…

Complex permittivity of soil is connection with volumetric water content robustly. Especially, Dielectric constant rapidly varies with volumetric water content because of the robust connection between volumetric water content and dielectric constant, if volu…

Bir manyetik mikromanipülatör farklı uygulamalar için gerekli manyetik kuvveti üretme kabiliyetine sahip olarak geliştirilebilir ve mikron boyutlu parçacıkları manipüle edebilir. Bu çalışma etkin ve otomatik mikro-parçacık manipülasyonu için geribeslemeli kont…

This study was carried out in the pure oriental beech forests of Yenice-Kızılkay in the Western Black Sea Region of Turkey, where the changes in the number of side roots and the changes in the height and diameter of the beech trees were examined in three diffe…

Multi-seeded YBCO superconductors (cylindrical size) 32 mm in diameter were fabricated by top-seeded melt growth (TSMG). Melt-processing was performed using a precursor containing 75 wt % of Y123 and 25 wt % of Y211 with 0.5 wt % of CeO2. Trapped magnetic fi…

DC-DC boost converters are usually used so as to increase voltage in battery charging of electrical vehicles, power factor correction circuits and solar photo voltaic panels etc. applications. The control of these converter types is realized with Pulse Width M…

Variable magnetic fields are widely used in energy production. Two methods can be applied to make the magnetic field variable. The first of these is to apply an alternating current to the insulated conductor on the outer surface of a core. The other is to rota…

ZnO nanopowders were synthesized via microwave assisted hydrothermal method at different precursor solution molarities. For this, the aqueous solutions of zinc aceatate dihydrate and sodium hydroxide were prepared at different molarity as precursor materials…

Courtyards hold significant functional value in both traditional and contemporary architecture. They serve as open-air spaces that facilitate social interaction for users within urban environments. In order for these spaces to be utilized more efficiently by u…
