Fuel cells can be considered as clean, efficient and economic devices for the next power generation. Flow configuration and operating conditions such as temperature, relative humidity and stoichiometric number are key factors for improving cell performance. …

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…

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…

When the traditional fuel reserves are limited and the environmental factors of these fuels are taken into consideration, the importance of renewable energy sources is increasing day by day. Especially, obtaining electricity from solar energy has become popula…

Proliferative activity of Epstein Barr Virus (EBV) proteins occurs via two mediators (Epstein Barr Nuclear Antigen1-EBNA1 and latent membrane Protein1-LMP1). In this study, it is aimed to investigate that recombinant viral EBV protein of pancreatic cell loss t…

In order to increase the performance/cost ratio of solar cells, new approaches reducing optical and electrical losses are necessary during the absorption of the light and collection of charge carriers. In this work we focused on various textures on Si surface …

The new material type is ‘cryogels’, which have important potential in biotechnology applications. Cryogels can be obtained from natural or synthetic polymers. It is seen that cryogens prepared from natural polymers become a preferred material group for tissue…

Diesel engines have been preferable engines for heavy, medium and light duty vehicle applications due to their superior performance and fuel economy. However, concerns with their emissions, which are highly toxic air pollutants, put some limitations to their w…

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…

Plants encounter a variety of environmental stress factors that affect plant growth, fruit yield and quality. Stress factors cause physiological dysfunctions, ion imbalance, depression in photosynthesis, leading to growth reduction and decrease in fruit qual…

Optimal operation of the power systems is very important. In this paper, a new approach for both the economic active power flow and active power loss minimization in multi-terminal HVDC systems is proposed. In the proposed optimization approach, system constra…

In this paper, a different approach for the optimal active power flow solution in multi-terminal HVDC systems to minimize total active power generation cost is proposed. System constraints for all of the control and state variables of both AC and DC systems ar…

This paper presents a different approach for the optimal active power flow solution in multi-terminal AC-DC systems to minimize total active power generation cost. System constraints for all of the control and state variables of both AC and DC systems are also…

Evolution of EU road transport emission standards indicates that the limits have been reduced more than 90% in the last decades. However, nowadays, the urban populations in many developed countries are still suffering from urban transport sourced emissions. On…

Ceramic materials are characterized by outstanding hardness, extreme compressive strength and elastic modulus, wear resistance, thermal shock resistance, chemical stability and high temperature properties. Therefore they have potential materials to be use at i…

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…

One of the most consumed energy sources today is fossil-based fuels. While the reserve of these fuels is declining, it continues to be the main cause of environmental pollution. Due to the influence of environmental factors and increases in fuel costs has acce…

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…
