Custom designed optical tweezer for trapping yeast cells

Çobanoğlu, Nur

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

Effects of ınternal marketıng on servıce qualıty ın accommodatıon busıness : a research for the fıve stars hotels ın Izmir

Sönmez, Gülser

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 effect of pulsed electromagnetic fields for in vitro wound healing exposure systems

Gümüşay, Mehmet

THE EFFECT OF PULSED ELECTROMAGNETIC FIELDS FOR IN VITRO WOUND HEALING EXPOSURE SYSTEMS SUMMARY Electromagnetic fields have achieved important role as stimulator and therapeutic facility in biology and medicine (Blank & Findl, 2013). The effects of low magnitude, low frequency pulsed electromagnetic fields have been a period of study since past few decades, which was mainly on the treating soft tissue injuries, skin ulcers, nonuniform bone fractures and degenerative nerve healing (Hug & Röösli, 2012b). Chronic wounds are a major healthcare problem for patient morbidity and contribute signi ...Daha fazlası

Fuzzy delphi method to direct urban renegeration project assessment: Bornova-Kızılay neighborhood

Çupı, Romjana

Resident satisfaction is an important issue in urban regeneration projects (URP). In the western countries, the resident satisfaction from residential environments continues to be an important topic for researchers and the data found well preserved and integrated into real projects. In Turkey, yet, there is little research on residential satisfaction in many urban regeneration projects implemented. In Turkey, up to the present, research carried out about urban analysis and residential satisfaction needed in any urban regeneration project, is little evident in implemented UR projects. Izmir is ...Daha fazlası

Boron doped titanium dioxide nanotube arrays: production, characterization and photocatalytic properties

Bilgin, Kübra

Photocatalytic degradation and complete mineralization of toxic organic compounds in water, soil, and air in the presence of semiconductor materials have received much attention over the last decades. Electronic structure of semiconductors is characterized by a filled valence band and an empty conduction band. When the semiconductor is irradiated with light of sufficient energy corresponding to or exceeding its band gap, an electron is promoted into the conduction band, leaving a hole in the valence band. The electrons and holes are good reductants and powerful oxidants, respectively, and they ...Daha fazlası

Expert system design by using artificial intelligence techniques for the diagnosis of liver disorders

Mülayim, Naciye

Nowadays, Expert System (ES)s are used widely in many areas to solve real world problems. Artificial Intelligence (AI) techniques are used to obtain timely and accurately decision about solution of daily problems in ESs designing because AI can mimic behaviours and thought system of people. Especially in medical area, there are many researches and applications using ESs based on various AI techniques to obtain diagnosis for any diseases. The liver is a vital internal organ for a human body and it has many functions, which are associated with the other organs. Although the liver can renew itse ...Daha fazlası

Investigation of concrete barriers with recycled rubber, steel slag and roof tile

Kurar, Ali

The purpose of aggregating rubber is to increase concrete’s flexibility, elasticity, and capacity to absorb energy. In some application of concrete, it is desired that concrete should have low unit weight, high toughness and impact resistance. Although concrete is the most commonly used construction material, it does not always fulfill these requirements. In order to improve elastic properties of concrete and recycle the waste materials, new applications have been realized recently. One of these applications is the utilization of discarded tires in order to use together with aggregate. ...Daha fazlası

Urban regeneration strategies for supporting social sustainability of Roma community: Izmir-Ege neighbourhood urban regeneration project

Cin, Mehmet Melih

Urban regeneration greatly affect marginalized groups both across the world and in Turkey and therefore it is a hot topic in the public discussions of urban context. One of those marginalized groups are Roma communities. Their neighborhoods, particularly inner urban areas, face social and physical decay due to discrimination against Roma communities. To address these social and physical problems, urban regenerations projects have been launched in Turkey in the name of improving life standards of Roma citizens. However, implementations could not go further than improving physical conditions of ...Daha fazlası

Fuzzy logic modelling of sediment transport in annulus

Müftüoğlu, Tevfik Denizhan

The understanding of sediment transport with fluid in pipes is one of the important issues in hydraulics engineering. If the fluid velocity is lower than a critical value, a stationary cuttings bed develops, which may cause excessive head loss. In this study, a Fuzzy Logic (FL) model is developed to estimate stationary cuttings bed thickness inside the annulus. Experimental data is collected from literature in order to train proposed models. Results showed that the cuttings bed thickness could be estimated using the developed model with a reasonable accuracy when compared with the experimental ...Daha fazlası

Characterization of Clay brick materials produced with red mud and nut shell wastes for building applications

Çam, Ata Sadık

In this study, clay based brick with micro pores was developed for thermal insulation in the building materials. Turkey produces about 70% of the world hazelnut production. The aim of this thesis is to reduce the thermal conductivity coefficient by adding organic waste (hazelnut shell) into clay mixture to form porosity during firing of clay bricks. Moreover, it is to maintain the similar mechanical properties by adding inorganic waste (red mud) into clay mixture. The development of a highly porous bricks with applicable mechanical strength will contribute to save energy in the building ...Daha fazlası

A preliminary offshore wind energy potential study for bay of İzmir: Quantifying the airflow distortion on local ferryboats for adjustment of wind data by 3D CFD analyses

Güngör, Şahin

Humankind have an interest to obtain marine meteorological data for decades, therefore, constant and mobile meteorological stations have been used for the correct measurements. These meteorological data include wind speed and direction, sea surface and air temperature and cloud cover. Ship-mounted anemometers have been used for meteorological observations, obtaining the wind speed data and climate change analysis. Wind data are especially gathered and reported by Voluntary Observing Ships (VOS). World Meteorological Organization (WMO) created the VOS program to ensure reporting of the wind dat ...Daha fazlası
