First and emergency aid technicians are health workers who work in emergency pre-hospital medical services and who need urgent care to be applied to the patient. First and emergency technicians are obliged to provide emergency prehospital care until the patien…

In last years, the use of alternative energy sources such as solar energy has become even more important because of environmental problems, especially the rapid depletion of fossil energy resources. There are works done for this purpose and solar energy applic…

The purpose of the study is to investigate the effect of motor vehicle taxes on the amount of exhaust emissions (emissions) in EU and Turkey. Firstly the taxes on motor vehicles in EU and Turkey was explained in terms of the subject, the taxpayer and the ap…

The monitoring of emissions caused by congested road traffic requires the deployment of a complex measurement system. The use of Wireless Sensor Networks (WSN) can be very useful. In this work we propose the architecture of sensors (devices) which are envisage…

Mining environments have faced with serious fatalities related to works, workplaces and workers as a consequence of their accident-prone processes. Underground mining stands in the first place in terms of being a hazardous industry worldwide. Due to risks invo…

With the effect of globalization, a significant change and transformation have been experienced. As a result of this change, developments in knowledge and information technologies caused an intense competition among both countries and businesses. In such an …

Energy dissipaters used in open channels are devices designed to reduce the flow velocity and allow water to pass downstream without harming water structures and environment. In this study the effect of energy dissipaters on energy loss is investigated depende…

In the world where tourism is developing rapidly, people travel more and are now turning to alternative tourism activities according to the conditions of the present day. In this context, it is observed that, in line with the socio-economic developments of the…

This study is related with numerical modeling of a Francis turbine draft tube. In order to reveal this relationship, a real Francis turbine model test results are used as inputs of the computational fluid dynamics (CFD) study. Firstly, the flow in divergent ch…

Plasticity index is one of the most important parameters affecting the behavior of fine-grained soils under monotonic and dynamic loads. Besides, various correlations between plasticity index and strength properties of fine grained soils can be obtained depend…

In this study, thermodynamic analysis of a geothermal power-based district energy conversion system which produces electricity, hot water, heating and cooling are investigated. The energy produced from geothermal resource can be utilized to drive a double stag…

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 …

The effects of climate change in the world are observed to have significant effects on different environmental variables. Therefore, changes in climate parameters should be examined and analyzed. These changes can be determined by parametric and non-parametr…

Current study is related with numerical simulation of a centrifugal pump impeller with the specific speed of nq=13. By the help of computational fluid dynamics (CFD) at different operating points, pump performance rsults (Head-Discharge graph) are obtained. Si…

Depending on the growing industry and population, energy needs are increasing day by day. In parallel, our external dependency on energy also increases. This issue made it necessary to use of renewable energy sources as much as possible. As an extension of eff…

The structure of the gas diffusion layer influences cell performance because it also affects the passage of reaction gases and electrons. In this study, the effect of the thickness of the gas diffusion layer on the cell performance for the singlecelled PEM fue…

Today, the universal development tool of the globalization in the world is ICT. Therefore, the capacity of using advanced tools of ICT in developed countries is increasing rapidly. Intelligent technological tools have become a part of our lives. Intelligent sy…

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…

Building automation and control systems (BACs) allow plants in buildings to be controlled and managed, thus increasing the users' comfort and reducing the operation and maintenance costs. As far as the lighting services are concerned, control systems offer an …

Wireless Sensor Networks have many application fields including both industrial and military usages. They are used for monitoring temperature, distance, light, and motion in laboratories and/or application specific environments. This paper focuses on developin…
