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…

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 …

Phthalocyanines (Pcs) have many uses in advanced technology. In recent years, the applications of MPc complexes have expanded to fields such as photodynamic therapy (PDT) photodetectors, photoconductive agents in photocopiers, and electrocatalysts, but these c…

Copulas are the special functions obtained with a combination of functions. Therefore, appropriate conversions can be made to create new copulas or to improve the existing copulas. Many researchers have recently aimed to obtain variables with higher correlatio…

In order to investigate the relationship between variables, it is necessary to reveal the dependency structure between variables and because of this reason, the concept of “copula” is being used in statistics literature in recent years. The main purpose of the…

Lubricant oils are products designed to form a protective film that reduces wear and friction of machinery moving parts, protect against corrosion, cool surfaces, and reduce energy consumption. During operation, lubricant undergoes chemical changes due to cont…

Together with rapid growth in population, industrialization and urbanization, environmental problems are also growing. Increasing human pressure on environment and resultant ecological destructions then come to the front as significant problems. At the end, it…

In today’s world with ever-aggravating environmental problems, environmental training has a great significance in mitigating and coping with such problems. Environmental pollution is the greatest problem today and certain measures and steps should urgently be …

The high consumption of surfactants throughout the world (more than 15 million tons/year), together with their toxicity and negative effect on the self-purification capability of surface waters, make these synthetic organic compounds one of the main environmen…

Bionic hand is a system consisting of many electronic and mechanical parts. Motion in the bionic hand system is achieved by motor control. One of the most complex organs of the human body is the hand. Bionic hand design has been studied in engineering and biom…

Transportation costs’ directly affecting national economies; increase in transportation costs depending on energy resources have directed the countries to develop combined transportation strategies to reduce transportation costs. In this study, it is aimed to …

The capitalist system’s entry of a crisis from the 70s has facilitated the "meta" of education, which first led to changes in the provision of educational services. Presentation of the education service at a price does not mean that the education is used for t…

We are at a time when electronic systems are structured in a manner similar to the human brain.The memristor, a neuromorphic circuit designed by Chua in 1971, is a modeling of synaptic learning and associative learning. Neuromorphic circuit elements and memris…

The study of nonlinear boundary value problems is a very important and difficult area of research in differential equations. The aim of our work is to establish the existence of solutions for a second order boundary value problem which models different real si…

This study aims to examine the relationship between employees' organizational commitment and happiness levels. Organizational commitment means that members of the organization strongly believe in and accept the organization's goals and objectives, to be willin…

The aim of this study is to determine the level of emotional intelligence and emotional intelligence levels that university students have. The concept of emotional intelligence was first revealed by Mayer and Salovey. Researchers describe emotional intelligenc…

When the weekly course syllabus of Hearing-Impaired Primary School is taken into consideration, it is seen that Turkish Sign Language (TSL) and Turkish courses are included in must courses. TSL course is 2 hours a week, whereas Turkish course is 10 hours a wee…

Open channel flow is defined as fluid flow with a free surface open to the atmosphere. One of the main sources of resistance in open channel flow is the roughness of channel bed. The roughness of channel base and side walls must be considered seperately invest…

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…

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…
