Bu çalışmada, ağırlıkça %0.1, %0.3 ve %0.5 oranında grafen nanotabaka (GNT) takviyeli alüminyum (Al) matrisli kompozitler toz metalurjisi metoduyla üretilmiştir. Üretilen kompozitlerin deneysel yoğunluğu, çekme dayanımı, aşınma oranısırasıyla; Arşimet yoğunl…
ZnO nanopowders were synthesized via microwave assisted hydrothermal method at different precursor solution molarities. For this, the aqueous solutions of zinc aceatate dihydrate and sodium hydroxide were prepared at different molarity as precursor materials…
Otel işletmelerinde çalışanların kişisel özellikleri bireysel ve örgütsel çıktılarını doğrudan etkilemektedir. Çalışanların işlerini kendi özelliklerine göre şekillendirmesi ve aynı zaman diliminde birden fazla iş yapma özelliklerinin olması iş performanslar…
2018 yılı verilerine göre 7,6 milyarı geçen dünya nüfusu her geçen gün artmaya devam etmekte ve bu artışla birlikte insanların ihtiyaçları da her geçen gün artmaktadır. Enerji ihtiyacı ise temel gereksinimlerin başında yer almaktadır. Enerji geçmişte ve gele…
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 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…
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…
In this study, an aerobic membrane bioreactor (MBR) system to treat a highly polluted mixed organized industrial zone (OIZ) wastewater was presented at laboratory scale. Flat sheet (FS) microfiltration (MF) and ultrafiltration (UF) membranes were used for the …
The performance and competitiveness of manufacturing companies depend on the production system and depend on the sustainability, productivity, reliability and protection of the expected functions of machinery and equipment in these systems. Their sustainable s…
In addition to developing information technologies, medical decision support systems are used to make decisions more effective, faster, more accurate and easier to make decisions in medicine and healthcare. With data mining, which is an important part of med…
Wireless Sensor Networks, used widely nowadays, are likely to be unprotected against a variety of external attacks because they are often used in outdoor applications. Protecting the network against attack and ensuring the safety of the data has always been im…
Low energy and water consumption of green buildings during the life cycle, waste management, minimizing the impact of projects on the ecosystem and increasing the use of environmentally friendly materials have made high performance green buildings attractive…
The construction sector aims to produce efficient projects by optimizing cost, quality and time. However, this is not always very easy. Projects may not be completed on time, budget may be exceeded or products may not be produced sufficiently high quality. For…
Various deteriorations primarily rutting occurs in hot mix asphalt under conditions of traffic, climate and environmental in length of time. To increase the resistance of mixtures and thus delaying these deteriorations, the various additives are added to the b…
Geocell, which is one of the increasingly used geosynthetic materials in recent years, limits the lateral movement of the ground with its three-dimensional honeycomb structure. Thanks to this new technique, the cost of the soil improvement methods and the cons…
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…
In last years, the use of alternative energy sources such as solar energy has become even more important because of environmental problems, especially the rapid depletion of fossil energy resources. There are works done for this purpose and solar energy applic…
