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
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
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
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
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
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
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
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
In environment of globalization and intense competition, businesses make
their long-term plans in order to sustain their existence. This planning ensures
employees to understand the points of organization’s mission, its goal, the place
where it wants to reach and how it will get there, and it is thought that organizational
communication plays an important role in this respect.
In this context, the main purpose of the study is to a research about discussion
of organizational communication and strategic planning process. In the research
where interview was preferred as data gathering tech ...Daha fazlası
In this study, the necessary data obtained from the databases (such as MSSQL, Mysql, Postgre SQL, etc.) of the softwares like ETA and NETSİS that are used for preaccountancy of the local and global companies were read, some of the data were written to the databases, and this data was used by the end user by using mobile phones or tablets carrying Android operating systems and working with Internet and cloud technology. In addition, new data sets that are collected on a cloud system from the accounting data while the company is on was studied by genetic algorithms which are one of the artificia ...Daha fazlası
In this work, the effect of temperature on the pressure loss of Newtonian fluid in a fully eccentric annulus with pipe rotation is investigated. For this purpose, initially comprehensive experimental study has been conducted at Izmir Katip Celebi University (IKCU), Fluid Mechanics and Hydraulics Laboratory of Civil Engineering Department. Effect of temperature has been observed for flow velocities from 0.7 m/s to 3.4 m/s, for pipe rotations from 0 rpm to 120 rpm, and for temperatures is from 20 °C to 65 °C. The pressure loss within the test section is recorded. An increase in the liquid temper ...Daha fazlası
The goal of this study is developing custom designed optical tweezer which uses two
He-Ne lasers (λ=632.8 nm) parallel to each other to trap yeast cells. The
characteristic specs of this optical tweezer determined by Brownian Motion of
polystyrene beads in water. Stiffness and trapping forces of optical tweezer
calculated for laser 1, laser 2 and when both lasers used simultaneously. Laser 2 can
trap and move particle to laser 1 and multiple particles can be trapped by the laser 1.
After determination of specs of optical tweezer, yeast cells in yogurt culture medium
were trapped by lase ...Daha fazlası
