In this paper, the steps in the production process of forming hybrid composite coatings on surface of the ZA-27 alloy known as a sliding bearing material, and analysis of surface morphology of the coated samples were investigated. The process includes forming …
Kanser küresel olarak ölümlere neden olan ciddi bir halk sağlığı sorunudur. Bu sağlık sorununun nedenleri genetik (%5) ve çevresel etmenler (%95) olarak iki gruba ayrılmaktadır. Çevresel etmenler arasında ise beslenme alışkanlıklarının kanser oluşumunda önem…
Alfa-sipermetrinin toksik etkilerinin araştırıldığı çalışmada, gökkuşağı alabalıkları pestisitin 3 farklı konsantrasyonuna maruz bırakılmıştır. 96 saatlik akut uygulama süresinde balıklardan 0, 24, 48 ve 96 saatlerde solungaç dokusu örneklenmiştir. Solungaç …
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 …
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…
In the fifth generation (5G), the traditional restrictions that limit the capacity of wireless communication must be overcome. Non-orthogonal multiple access (NOMA) is a promising solution capable of overcoming these constraints to meet the requirements of 5…
Hydroxyapatite/polymer composites are promising materials for drug delivery applications. Studies focusing on the development of such composites are available in recent years, as using these materials as a carrier allows us to overcome the side affects of to…
Electrochromic polymers are conjugated systems that have an ability to change their colors upon applied potential. These systems are potential candidates in various technological applications such as organic solar cells, light emitting diodes, smart displays a…
Plastic injection molding is a manufacturing process of heating plastic granules and forcing melted plastic into a mold cavity and removing from the mold after cooling. One of the most important elements in the production of parts by plastic injection molding …
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…
The effective control and treatment of chronic diseases requires access to diagnostic tests that are rapid, reliable and very sensitive. Nucleic acid based methods of pathogen detection technologies offer very rapid and accurate results with high sensitivity a…
This paper describes a laboratory application for the forecasting the dielectric properties, using an artificial neural network embedded in a microprocessor. The dielectric permittivity and loss factor of the insulation material were determined as a function o…
