Bu çalışmada plastik malzemeler üzerine yapılan metalik kaplamalar incelenmiştir. Metalik kaplamalarda katman kalınlığıyla ilişkili olarak termal yük altında termal genleşme sebebiyle oluşan gerilme dağılımları araştırılmıştır. Çalışmada silindir çubuk, kiri…

Timber structures are used as building elements in ancient times due to the lightness and durability. Formwork material of reinforced concrete structures are also made of wood. Although timber is widely used in industry, it has been limited research in liter…

This study was focused on earthquake induced tsunamis to prepare source parameters for accurate estimations of what would be the maximum heights and the shortest time of the arrival of the tsunami waves in Aegean Sea coastal areas of Turkey. Since the earthq…

Using pure water in the determination of the fiber density is a well-known technique and a simple method. But, it is known that using water in the determination of textile fibers is not sufficient. Thus, the aim of this study is to produce a simple technique…

In this study water samples were collected from 30 villages located in the Ergene River Basin in summer season of 2018. Nitrate (NO3) and nitrite (NO2) concentrations of water samples were determined and the results were assessed according to national and in…

In this study, the problem of discharging of the water in a rectangular tank from the orifice with square crosssection was investigated experimentally and numerically. Time evolution of the water level, obtained experimentally by using image processing techni…

Erosion is among the leading factors threatening our sources of soil and water. The use of soil susceptibility indices to determine erosion and risk situations has an important place especially in erosion studies. The susceptibility of soil to erosion is the…

Çarpan jetler, iyi bir ısı transferi performansı sağlamaları nedeniyle genellikle sanayide elektronik ekipmanların ısıl problemlerini çözmek için kullanılırlar. Bu çalışmada, tek bir hava jeti akışı kullanılarak bir tarafı açık, üç tarafı kapalıdikdörtgensel…

In this study, a thermoelectric generator (TEG) system is designed for the generation of electricity from solar energy. A temperature difference between surfaces of TEG must be achieved for electricity generation. Heating is provided by a solar-powered two-p…

Yozgat is one of the comparatively large provinces with its surface area and ecological diversity. It contains four different agroecological sub-regions. This variety allows the production of different crops. However, the existence of geothermal resources is…

Polycarbazole (PAAC) and poly (thiophene) (PTH) are both highly stable polymers. But the conductivity of (PAAC) is much lower than PTH. When polycarbazole and polythiophene alternative copolymers are synthesized, it is aimed to increase the conductivity of PAA…

Due to the population growth, the use and management of natural resources has been one of the most important issues while ecological studies are gaining importance. In this context, the use and management of water which is the main source of life has had a maj…

In this study, mixed convection heat transfer and fluid flow in a three-dimensional horizontal duct with three different geometries of cavity were investigated numerically. Air flows in a square duct which is heated by a cavity with triangular, a rectangular a…

Size of damage caused by an earthquake depends on the amount of energy released by the current stress accumulation of the active faults and the change over time. Stress accumulation on a fault occurs in two types. These are 1) the long-term tectonic movements …

This study aimed to develop natural dyes for wood material that are harmless to humans and the environment. For this purpose, a tea stain and polyurethane single- and double-component water based varnish were applied by brush on the wood surfaces of pine (Pinu…

In this study, spruce wood’s boric acid and nano technological varnish different vacum/ diffusion in time impregnating with respect to ASTM 1413-76 standards and the changes on technological features are researched. Retention percent, bending strength, modulus…

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…

Over the past decade, gold nanoparticles (AuNPs) have stimulated great interest in various types of sensors because they possess many attractive properties such as optical, electronic and chemical features [1]. In order to gain more intrinsic properties and …

One of the materials that are increasingly used today in various engineering applications is boron steels. Though boron steels draw attentions with their superior wear characteristics, studies on the tribological properties of these materials is quite limited …

Yenilikçi soğutma teknolojileri arasında yer alan ısı boruları, sahip olduğu özgün karakteristikler sebebiyle son yıllarda önemli bir araştırma alanı olarak ortaya çıkmaktadır. Isı boruları, taşınımla ısı geçişi ve sıvı-buhar faz değişimi ilkelerinden faydalan…
