3D (Dimensional) microtissues are commonly used in regenerative medicine, medicine design, toxicology studies and advance cancer research. Microtissues which are constructed by this technique mimic natural in vivo condition and it stands for shifting form between in vitro studies and in vivo research. Scaffold-free microtissues produce own extracellular matrix and cells proliferate faster. However microtissue is used in vitro experiments, they mimic in vivo condition by producing own matrix.
Recently, RGD peptides which are commonly used biomaterials consist of GRGDS sequences and it has acti ...Daha fazlası
Within the scope of the thesis study, interpolation methods used for evaluating spatially varying data and for presenting the information obtained from the data via maps were investigated. A method for generating an open source web based interpolation map for the most commonly used interpolation methods is presented. Today, many commercial Geographic Information Systems (GIS) software are used in the production of interpolation maps. However, this situation causes the users to pay a large amount of money or use cracked programs. Although there are open source softwares, which can create interp ...Daha fazlası
ABSTRACTIt is not possible to produce steel without inclusions as the process for steel production requires. Based on this fact, the researches on clean steel are concentrated on the reduction of inclusions and transformation of inclusions into harmless state by modification. The definition of steel cleanness is related to final product application. Non-metallic inclusion, in the liquid steel, causing many problems and production lost in steel production process and final application. Aluminum killed steels mostly contain Al2O3 and MnS inclusions. Al2O3 inclusions are formed during de-oxidatio ...Daha fazlası
The concept of internal marketing is discussed in the literature more than ten
years. Despite the rapid increase in publications related to the subject, many
companies are benefiting from this concept in practice. Many businesses still do not
know exactly what the concept is and how to apply it. The most basic reason for this
is that the research on the concept is rather limited and inadequate. This makes
practical research more essensial among with descriptive research for the concept.
This study examines the effect of internal marketing practices on the quality of
service hotels. The ...Daha fazlası
The carbon fiber used in the manufacturing of advanced composites has various applications in the automotive, aerospace, and electronics industry because of their comprehensive properties such as lightweight, flexibility, high strength to weight ratio, excellent chemical resistance, superior electrical conductivity and thermal conductivity.
Different kinds of carbon fiber precursors have been used and polyacrylonitrile (PAN) is the mostly utilized polymer type which is a petroleum-based, expensive and unsustainable. Remarkably, lignin is a highly accessible, low-cost, and renewable resource. ...Daha fazlası
In the context of a globalized economy, economic institutions must adapt to
the competitive environment in which to be profitability is not enough anymore,
they must also satisfy a creative, secure, socially acceptable working conditions for
employees in order to increase the productivity. The concept of global performance
refers to the need to discover and activate simultaneously the various levels of
success, and in particular to pay particular attention to the steering and optimal use
of Human Resources.
Human resources are the basic driving power of a production economy. If

Today, tissue transplant applications are widely used for repair of damaged hard tissue. Despite the gold standard of autografts, interest in synthetic bone grafts produced by tissue engineering techniques is increasing day by day, due to limiting factors such as damage to the tissue site and limited graft availability in allografts, and the risk of developing an immune system response in allografts.Many bioceramic materials, including β-tricalcium phosphate (β-TCP), hydroxyapatite (HA) and calcium sulfate, are widely used in bone tissue engineering. β-TCP has been the most preferred biocerami ...Daha fazlası
Graphene, a one-atom-thick two-dimensional material, has drawn great interest for many electronic and optoelectronic applications due to its extraordinary properties. The properties of the graphene can be modified with different chemical methods and introduced new properties, which widens its potential for applications. The non-covalent modification of graphene is one of the basic techniques for modifying the electrical properties of graphene without disrupting the structure.
In this thesis, the high-quality graphene has been synthesized and electrical properties of graphene have been tuned b ...Daha fazlası
ABSTRACTDiabetes Mellitus (DM) is a chronic disease that progresses rapidly. Today, thenumber of diabetic patients is increasing day by day, but treatment methods arebeginning to be inadequate due to the insufficient time, financial deficiencies andother restrictions. Diabetes education and treatment are very important for thediabetic to survive. Diabetes treatment is practiced in many areas of life from thenutrition habits to the social life activities. In terms of the course of diabetestreatment, it is necessary for the self-management of the patient to follow thediabetes education and appli ...Daha fazlası
ABSTRACTCities that have a history as a capital or an important trade center, has its own complex structure. If the historical city center was functionalized as a commercial district, it has been experienced social, cultural, environmental and economical subjects throughout centuries. This situation creates strong impacts as newly created contexts likewise political, public and architectural. These contexts generally not thought together, but they should be analyzed and investigated together for a sustainable future for the historical city centers. As a historical city center, Kemeralti-Izmir ...Daha fazlası
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
This thesis focuses on a Multileaf Collimator design that can shape the beam contour to fit the shape of target geometry and its design improvements. Main purpose of this design is lowering the number of leaves on the multileaf collimator and making the system easier to be controlled. As the Collimator devices undertake the most important point of the beam shaping procedure, ease of control and precision of collimator devices are the major points of operation.
As the radiation therapy is one of the most complex and vital medical operations, this thesis started with the deep literature survey ...Daha fazlası
