Masif odun ve odun esaslı kompozit malzemeler, elde edildikleri ağaç türüne göre farklı sertlik değerine sahiptir. Bu özellik ahşabın kullanım alanında önemli bir faktördür. Bu çalışmada, doğu çınarı (Platanus orientalis L.), dut (Morus Sp.), kızılçam (Pinus…
Additive manufacturing which is developed in the last half century is promising manufacturing technology. It uses layer-wise production method for obtaining finished product. In recent years, thousand researches were made but there was still gaps about impac…
In this study, hybrid composite structures were manufactured by vacuum assisted resin transfer molding method using three different woven fabrics (jute, E-glass and carbon) as the reinforcing material and polyester resin as the matrix material. All composite…
Yenilenebilir enerji kaynaklarından güneş enerjisiyle elektrik üretimi için yaygın olarak fotovoltaik (PV) modül kullanılmaktadır. Her sistem gibi bu sistemlerin de verimli olması istenir. Bir PV modülün elektriksel verimini düşürebilen pek çok faktör bulunm…
In many engineering applications such as aerospace, automotive and telecommunications, icing leads to mechanical and socio-economic problems such as efficiency reduction, decreased power transmission, security threat, material damage and energy waste. Theref…
Transition metal complexes are playing an important role the field of bioorganic chemistry. it has been attempted to investigate the anti-cancer properties of complexes of 2-benzimidazole derivatives formed with various metal atoms [1-2]. In these examinatio…
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…
In this study, a thermoelectric generator (TEG) system is designed for the generation of electricity from solar energy. A temperature difference between surfaces of TEG must be achieved for electricity generation. Heating is provided by a solar-powered two-p…
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…
Çarpan jetler, iyi bir ısı transferi performansı sağlamaları nedeniyle genellikle sanayide elektronik ekipmanların ısıl problemlerini çözmek için kullanılırlar. Bu çalışmada, tek bir hava jeti akışı kullanılarak bir tarafı açık, üç tarafı kapalıdikdörtgensel…
Titanium and titanium alloys are suitable for a variety of applications, with their low density, high strength and high corrosion resistance. Despite strong mechanical and corrosive qualities, titanium use is restricted by its weak friction and wear characteri…
Wooden reels are wood-based products used in products requiring winding up such as cable, rope, plastic hose. Wooden reels are usually produced in diameters ranging from 40 to 320 cm and mostly from Turkish red pine (Pinus brutia) and black pine (Pinus nigra) …
Destination image refers to the mental schemes, beliefs and ideas of individuals about a place or destination. In the development of tourism, it is of utmost importance that the important products, the destinations, are made known and have a positive image in …
The fact that cannot be avoided the non-renewable energy sources (fossil and underground resources) are rapidly depleting, makes the search for new sources of energy extremely important in our country and all over the world. Besides, from past to present, due …
In this study, combined thermal radiation and natural convection heat transfer problem are investigated in glass and plastic covered flat solar collector. The bottom plate that absorbs the sunlight and the ambient temperature are kept constant. Solar collector…
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…
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…
Urban areas have less vegetation than natural environment that surround it. Differences between these types of areas affect climate, energy use, and habitat in cities. In urban areas, dark surfaces and reduced vegetation warm affect the air over urban areas, l…
The waste problem has become a non-ignorable issue in apparel industry like other manufacturing industries and the concept of sustainability has come to the forefront. The term ‘sustainability’ refers to the long-term viability of business operations and their…
