LEDs that emit blue light are needed to create white light using LEDs. In 1991, Japanese scientists Isamu Akasaki, Hirochi Amano and Shuji Nakamura invented LEDs that emit blue light. From this date it became possible to use the LEDs as lighting elements. Rapi…
Bu çalışmada birer adet ikili Al-9Si, üçlü Al-9Si-0,1Sr ve dörtlü Al-9Si-0,1Sr-0,6Mg alaşımı indüksiyonlu ergitme ocağında ergitme ve oda sıcaklığında tutulan kokil kalıba döküm yöntemi ile üretildi. Alaşımların yapısal ve mekanik özellikleri üretilen alaşım k…
The industrial–style designs affecting today’s perception of designs in a huge velocity has emerged first by the industrial revolution. Although being time–dependent and taking longer time and economically highcost product, the handcraft has allowed the indus…
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…
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…
Scientific and technical field of multiple disciplines working on lighting, is of great importance in our daily lives. Especially when energy saving is aimed at illumination of houses, other elements are mostly ignored. This situation, which affects our physic…
Many situations in human life are described with uncertain narratives. The fuzzy set theory has revealed as a powerful tool to deal with the uncertainty of human thoughts and expressions, by Azerbaijani Prof. Dr. Lotfi A. Zadeh in 1965. In the classical cluste…
Green tea, is a product obtained from less or non-fermented leaves of Camellia sinensis than black or oolong tea. It has been reported that green tea has more health benefits compared to black and oolong teas which are more fermented. The main components that …
Deneyim, tarih boyunca birçok düşünür tarafından farklı açılardan değerlendirilerek herhangi bir kavram olmanın ötesinde bilgi edinmenin bir kaynağı olarak görülmüş, bilginin kendisi olarak ele alınmıştır. Dolayısıyla mekânın tanımlanmasında deneyim şarttır ve…
Veritabanları verileri dijital ortamda düzenli bir şekilde saklamamızı ve istediğimiz zaman bu verilere en hızlı ve güvenli bir şekilde ulaşmamızı sağlayan yazılımlardır. Bilgi teknolojilerinin gelişmesine paralel olarak veritabanı sistemleri gelişmekte, her…
This study was conducted to assess the effects of 5 types of water: Ozonated, Chlorinated, Celestite Stone-treated, Natural Spring Waters and PinResin-treated water on performance, oxidative stress and carcass parameters in Japanese quail. A total of 150, 3-…
Many well-known material structures, such as metals, ceramics or polymers, cannot meet all the technological demands. For this reason, there is ongoing research into new materials with advanced features. A composite material is consisting of at least two phase…
Teknoloji günümüzde her alanda kullanılmaktadır. İnsansız Hava Araçlarının da çeşitli sektörlerde (İHA) kullanımı gün geçtikçe artmaktadır. İlk zamanlarda askeri amaçlar için kullanılan İHA teknolojisi, günümüzde jeodezi, tarım, meteroloji, iletişim, acil du…
Since the design of the first high rise building, the “Home Insurance Building” erected in Chicago in 1884-1885 only with 11 floors, new technologies encourage the designers to build taller and slender buildings penetrating through the sky. In the history, h…
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…
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…
Bu çalışma ile bireylerin renk tercihlerinin aldıkları eğitime göre değişip değişmediği araştırılmaktadır. Çalışmada çevresel imajı oluşturan ‘renk’ kavramı bağımlı değişken olarak, bireylerin eğitim durumu ise bağımsız değişken olarak ele alınmış ve bu iki …
Palladium-catalyzed Suzuki Miyaura cross coupling reactions (SM Coupling) are made using organoboronic acid and halides. 9-(4-anthracene-9-yl-phenyl)-9H-carbazole (III) was synthesized by using Ullman and Suzuki coupling reactions. Structural analysis of the…
Lower limb exoskeletons are wearable robotic devices which either augment human power or facilitate a walking ability for those who lost it by injury or aging. They have been getting more and more attention in the scientific community thanks to its increasin…
