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

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

Manufacturing and characterization of thermal conductive polymeric composite materials Termal iletken polimerik kompozit malzemelerin üretilmesi ve karekterizasyonu

Kaya, Nusret

ABSTRACTElectronic industry is growing dramatically in the last quarter of the century. Recent advances in electronics industry enable the miniaturization of micro transistors and the integration of more transistors into the electronic devices, resulting in a higher performance device. However, this condition increases the heat flow in the electronic devices. The performance of electronic devices depend on the working temperature, for this reason, it is important to remove the heat produced in the device as fast and efficiently as possible in order to hold the system temperature of the electro ...Daha fazlası

Development of 3D-Printed plastic based low-cost sensing systems 3D baskılı plastik bazlı düşük maliyetli algılama sistemlerinin geliştirilmesi

Bayram, Abdullah

ABSTRACTEnvironment and health is two important things that are so important to human lifebecause they cannot be separated from each other. The problems related with thesetwo events will negatively affect human life. Therefore, health and environmentalproblems should be monitored with proper testing devices and analyzed. In order toperform these tests, we need cheap, reliable and fast test equipment. With therevolution of three-dimensional (3D) printing technology that is cheap, practical, fastmethod of production, this kind of test devices can be produced. This productionmethod is used to pro ...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

Finite element analysis of material and parameter effects in ballistic armors Balistik zırhlarda malzeme ve parametre etkilerinin sonlu elemanlar yöntemiyle analizi

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

A research on the development of International and Domestic banks in Afghanistan and their role in Afghanistan Economy

Ayamı, Masood

In this thesis the development of Afghanistan’s banking system and the role of domestic banks in the economy of Afghanistan has been researched. Moreover, the effects of banks and the banking system to business sector, financial sector and to private sector in the country have been handled. Most of banking system was dead over 25 years of war due to abnormal condition in the country. After the new regime, the development of banking systems takes a new look in 10 years across the global transaction. Thus, get the positive feedback in these years. This change also played a big role in Afgh ...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
