The dimensions of discrimination in Turkey was not discussed much. Furthermore, the policy made with it is not paid attention. The ideological tools and mass media also can be responsible for this issue. The emergence of discrimination should be a matter of …
According to the political economy theory and neoclassicists, institutional discrimination is one of the obstacles that we face in politics in modern countries. It is generally systematic and malicious. In doing so, patronage relationships come into play. Ec…
Leadership is to orient and promote individuals for a specific purpose. Transformational leadership is the one who initiates change that makes employees believe in innovation and change. The transformation of the transformative leader in the formation of inn…
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…
Renewable energy can be produced by using kinetic energy of the flowing water such as rivers, ocean currents and tidal flows. The kinetic energy can be transformed to the power by hydrokinetic turbines. There are many different designs of hydrokinetic turbin…
As the world is running out of fossil fuels and the environment is being seriously damaged by the combustion residuals of the internal combustion engines, the world countries have begun to search alternative ways for mobility. Lightweight electric vehicles w…
Bu çalışma; havadan havaya bir atık ısı geri kazanım uygulamasında ısıl performansı etkileyen faktörlerin optimum değerlerinin araştırılması üzerinedir. Sistemde ısı transferini gerçekleştirmek üzere polimer malzemeden imal edilmiş çapraz akışlı plakalı ısı de…
In recent times, anthracene-based organic thin film transistors, organic light emitting devices (OLEDs), solar cells and dye sensitized solar cells can be used to due to such features achieve high efficiency effective charge excellent and carrier mobility. Ele…
The mobile processors with the increasing computational capabilities and software supports for the devices equipped by them have attracted the researchers’ attention to check whether they can be used for solving complex problems or not. In this study, a mobile…
Oscillators are one of the most important basic circuit blocks frequently used in electrical-electronics engineering applications. Among several types of the sinusoidal oscillators, quadrature oscillators are frequently used in communication circuits, control …
Organic dyes and complexes such as phthalocyanines (Pcs) may show photocatalytic properties against to photocatalytic degradation of pollutants [1]. The use of metallo phthalocyanines as organic photocatalysts in solution derives from their intense absorption …
In order to evaluate different modeling techniques for Unglazed Transpired Collectors (UTC), not only mathematical modeling method for UTC based on heat transfer expressions to estimate the various heat transfer coefficients for the UTC components and empirica…
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 …
Cementation steels; surface hardness is high and abrasion resistant materials.Also, cementation steels are materials with the alloyed or non-alloyed structure which materials used in the manufacture of parts which are resistant to shock and variable loads.Addi…
Analog filters have an important role in modern communication systems. Filter circuits with low noise, which occupy less chip area and consume less power as well as operate in the high-frequency region, are required with the developing technology. In the liter…
In this work, the effect of Ti addition (0, 1, 3, 5, 7, 10 wt%) on the electrochemical properties of Al-25Si alloys fabricated by melt spinning was investigated. Preparation of anode materials, the spinned types were powdered by cryomilling. The electrochemica…
The major part of freight transportation in Turkey is conducted by highway, the increase in the number of trucks and other heavy vehicles, as well as legislations allowing an increase in axle load that lead to deterioration such as rutting in flexible road pav…
