Evaluation of Polymeric Composite Material Alternatives for Metal Fulcrum Ring Part Used in Dry Friction Clutches

Ibrahim Can KAYMAZ

As same as in other industries, the automotive industry is one of the industries that expects continuous improvements. In this context, it is very important to integrate new technologies into the industry and to use new, alternative materials for industrial products. With the increase of these studies, cost and weight reduction are improved while serious advantages are obtained by maintaining the product's performance. The suitability of production with additive manufacturing of the fulcrum ring, which is a sub-component of the clutch cover assembly in the dry friction clutch system, acts as a ...Daha fazlası

Effect of Sediment Load on the Time Evolution of the Morphology of a Large-scale Laboratory Movable-bed Symmetrical Confluence

Zehra Büyüker

Akarsu kavşakları doğal drenaj ağlarının temel unsurları olup oluşturdukları habitat yüksek ekolojik değer arz etmektedir. Yan kollardaki sediment yükü ve akım arasındaki etkileşim kavşak morfolojisini düzenleyen önemli bir faktördür. Yan koldan gelen sediment yükü ve debinin ana kanal boyunca yer yer oyulmalara ve yığılmalara sebebiyet verdiği, bunların sonucunda da taban topoğrafyasında zamana bağlı değişimlerin olduğu gözlemlenmektedir. Bu çalışmada İzmir Kâtip Çelebi Üniversitesi Hidrolik Laboratuvarında bulunan, simetrik iki yan kolun 90˚ açı ile ana kanala bağlandığı açık kanal kavşağı ü ...Daha fazlası

Recycling of dental zirconia residuals resulting from CAD/CAM milling process Submitted

Merve TORMAN KAYALAR

Pre-sintered zirconia blocks stabilized with 3 mol% yttria are the most widely used dental materials in dental prostheses due to their high mechanical strength, high oxidation and wear resistance, high hardness, and excellent biocompatibility. Thanks to the processing of dental blocks with the CAD / CAM process, aesthetic restorations with excellent precision and high surface quality can be produced. However, only 30% of the blocks processed during the CAD/CAM process can be converted into products, while some of the remainder turns into dust and is collected in filters, and the other part bec ...Daha fazlası

Neurovascular Co-Cultures in hydrogel building blocks Hidrojel bloklarda nörovasküler ko-kültür çalışmaları

Ersoy, Fulya

ABSTRACTCreating a tissue or an organ model is the most emerging field of the biomedical research for the last decades. Three-dimensional scaffolds that will mimic the extracellular matrix were designed and used in various applications to investigate the behavior of cells.In this study, both the synthesis of the polymer and the fabrication of three-dimensional hydrogel scaffolds were practiced. Gelatin methacrylate (GelMA) was synthesized prior to photopolymerization of the hydrogel. A novel scaffold fabrication device was designed and manufactured. This device allowed us fabricating computer ...Daha fazlası

Antitumor effect of RGD peptite on cancer microtissues RGD peptidin kanser mikrodokuları üzerinde antitümör etkisi

Aydın, Veli Kaan

ABSTRACTCancer studies continue to gain interest in the recent period. Many types of cancer,especially breast cancer, continue to cause deaths worldwide and the number of people suffering from this disease is increasing. The methods that are used most at the basis of cancer studies are starting with 2-Dimensional (2D) cell culture. However, 2D cell culture can no longer adequately reflect in vivo conditions. Scientists have turned their efforts towards these 3-Dimensional (3D) cell cultures. There are many different ways of obtaining 3D cell culture. The preferred 3DPetriDish ™ technique in th ...Daha fazlası

Increasing the efficiency of dye-sensitized solar cells using ionic liquid based electrolytes Boya duyarlılaştırılmış güneş pillerinin verimlerini iyonik sıvı esaslı elektrolitler kullanarak artırmak

Mustafa Yaşar

ABSTRACTIn the last century, the energy demand of the world has been continuously increasing, and new and more environment-friendly energy sources search continues.As a result, Solar Cells have emerged as a renewable energy type. With the fact that when the sun is used efficiently it is a constant source of energy and a never-ending source of energy all over the world, triggering scientific studies on this subject and intensifying studies on solar batteries.With the influence of the economic factors in the materials, this issue has come up in three phases day by day. The fact that it is cheap, ...Daha fazlası

Development of microstructural and mechanical properties of aluminum alloys by equal channel angular pressing (ECAP) process Eş kanal açılı presleme (EKAP) yöntemiyle aluminyum alaşımlarının mikroyapı ve mekanik özelliklerinin geliştirilmesi

Yeşil, Mehmet Mahsun

ABSTRACTSevere Plastic Deformation (SPD), applying extreme force to alterate and refine the structures of materials permanently, have a huge potential to improve the mechanical and structural properties of materials superiously. ECAP is a kind of SPD techniques to produce submicron or nano sized grains in the material structure by applying stress to the sample passing through two angular intersected channels have the same diameters. ECAP has recently been becoming one of the most favourable candidate method in the production of nanostructured materials.One of the main objectives of this study ...Daha fazlası

Incubator monitoring system for newborn infants using Raspberry PI Raspberry pi kullanılarak bebek kuvözü izleme sistemi geliştirilmesi

Selek, Mehmet Hakan

ABSTRACTPreterm newborns are unlikely to live without any additional support. Babies born in this way need special care and a place that would imitate their mother’s womb as much as possible. The environmental conditions like the temperature, humidity, noise, light intensity, etc. need to be carefully managed. In addition to managing the environment, it is necessary to record vital data such as baby's temperature and pulse and record any changes so that they can be examined later. Since the systems that carry out these mentioned controls are very expensive, there are still hospitals that do no ...Daha fazlası

Latif Tibet Aktaş

ABSTRACTBulletproof composite armor models are investigated using finite element software ANSYS/AUTODYN. A composite plate is modelled with Kevlar 29/epoxy, analysed, and the results obtained by this model are confirmed with the results available in the literature. Different materials are tested as secondary materials in the composite plate. The results obtained by these materials for unit weight and for residual velocities of the projectile are compared. A new stacking sequence study is conducted with the Kevlar 29/epoxy as primary material and Ultra High Molecular Weight Polyethylene (UHMWPE ...Daha fazlası
