The hot-injection is one of the most used chemical synthesis methods to be able to produce nano- and/or micron sized particles in a liquid medium. Synthesis of nanoparticles of group II-VI semiconductors such as ZnO, ZnSe, CdSe and IV and V metals such as Pb…
Güç sisteminde akım ve gerilimin dalga formunun sinüsoidal formda olması gerekir. Fakat bu her zaman mümkün olmaz. Non-sinüsoidal gerilim veya elemanlar güç sisteminde harmoniklerin oluşmasına sebeb olur. Harmonikler güç sisteminde, ek ısıl kayıplara, rezona…
In this study, the effect of using a mixture of butanol and diesel fuel in a small diesel engine on engine performance and exhaust emissions is modeled. A comparison has been made with artificial neural networks, which is an up-to-date method, and multiple l…
Bu çalışmada ülkemizin petrol ihtiyacını azaltmak, yerli üretimi geliştirmek ve ülkemiz ekonomisini daha da artırmak için yapılan pek çok çalışmalara ek katkı sağlanması amaçlanmıştır. Mikroalglerin yüksek verimlilikte biyodizel sunması ve çevreye duyarlı ol…
Increasing number of motor vehicles together with economic development brings serious air pollution problems. Especially, Particle Matter emissions from Internal Combustion Engines are difficult to control and highly dangerous for human health. Both Europa and…
Coils are electrical-electronic circuit elements and they are obtained by winding conductive wires on top of one another on a core or space, when electrical current pass through the coils they bring a magnetic field around them. The electromotive force (emf) t…
Bu çalışmada, non-lineer ve dengesiz yükün bulunduğu güç sisteminde aktif filtre kullanılarak harmonik distorsiyonun değeri düşürülmüştür. Pasif harmonik filtrelerin aksine, modern aktif harmonik filtreler, güç faktörü düzeltme, gerilim regülasyonunu saglama…
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 first phthalocyanine compound in the class of macrocyclic compounds was obtained as a dark blue colored byproduct during the synthesis of o-cyanobenzamide from acetic acid and phthalimide in 1907 [1]. 20 years later, the first copper metallophthalocyanine …
Metal foams are light cellular materials that are a natural inspiration. Wood, bone and sea sponges are some wellknown examples of such structures. Metallic foams offer excellent mechanical response combination with lightness, good thermal and sound insulation…
Boundary-value problems with eigenparameter dependent boundary conditions is one of the most extensively developing fields in pure and applied mathematics. First, we cite the works of Walter and Fulton, both of which have extensively bibliographies, a discus…
The most fundamental role of the banking system is to direct funds into the real sector. In all country economies around the world, banks play an important role in transforming savings into investments by acting as a bridge between the financial sector and the…
Solar energy from renewable energy sources can be used for different purposes. The most common areas of use are electricity generation and preparation of hot water. While photovoltaic (PV) modules are used for direct electricity production, commercial vacuum…
It is well-known that the Sturm-Liouville type boundary value problems appears in solving many important problems in physics. For example, some problems of theory of elasticity in a half-strip ,the problems of theory of vibrations of an elastic cylinder redu…
Recently, the basis properties and eigenfunction expansions in various function spaces of the eigenfunction of the regular boundary value problems with spectral parameter in the boundary conditions have been investigated by many mathematicans. However in diff…
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…
In today's increasingly competitive environment, cities like businesses need to strengthen their image. Cities with a strong brand image attract attention by providing a distinctive feature. In the development of the cities, the images that contribute to the d…
Foreign trade signifies the commencement of economic globalization and it dates back to the post industrial revolution era. Although several fluctuations were observed among different economic periods, it never lost its importance. It is seen that both the cla…
Today the concept of globalization is seen in every part of daily life. It effects and changes a wide span of casual life such as from sports to economy. Today all economies have been integrated to the world economy at different levels. In the process of econo…
