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
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
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 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 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

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
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
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
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
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
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
