Comparison of the Methods Used in Acquisition of Private Property in the Scope of Public Interest

Tolga Kahyaoğlu

Public institutions need movable and immovable property, resource and altitude rights in order to perform their duties and services imposed on them by the constitution and laws. It is possible for public institutions to obtain these needs by renting or purchasing them by making a contract like all other real and legal legal persons. However, if the person who owns the properties or rights required by the Public Institutions does not want to make a contract, or if the price cannot be agreed upon, it will lead to the disruption or non-fulfillment of the duties and services required to be f ...Daha fazlası

Artificial Intelligence Based Android Assistant for Colorimetric Detection

Vakkas DOĞAN

A colorimetric analysis is a technique that measures the properties of the substance using color changes in chemical or biochemical analysis. It is vital in analysing biological, medical, and environmental samples in many fields, such as the food, medicine, cosmetics, and paint industries. Colorimetric analysis requires correct measurement and calibration techniques to obtain accurate results.

Development of Multi-Walled Carbon Nanotube-Based Flexible Screen-Printed Disposable Electrodes for Sensor Applications

Submitted to the Graduate School of Natural and Applied Sciences in partial fulfillment of the requirements for the degree of

Millions of people worldwide suffer from diabetes and diseases caused by diabetes. As a result of the statistical studies carried out by the World Health Organization (WHO), the number of people suffering from diabetes was 108 million in 1980, then it was increased to 422 million in 2014. Diabetes is increasing rapidly, particularly in underdeveloped and developing countries and it was predicted that 1.5 million people died because of it only in 2019 (WHO, 2021).

A design of ethylene Removal non-woven textile by using natural zeolite and potassium permanganate = Doğal zeolitler ve potasyum permanganat kullanılarak etilen tutucu dokusuz yüzey tekstil ürününün tasarlanması

Duru, Ayşenur

A DESIGN OF ETHYLENE REMOVAL NON-WOVEN TEXTILE BY USING NATURAL ZEOLITE AND POTASSIUM PERMANGANATE ABSTRACT Ethylene has a significant role in plants development and maturing and isproduced as gas hormone by plants themselves. In 1 μL L-1 concentrations, it has beneficial effects for fresh vegetables and fruits (FFV) but when this gas is accumulated around the FFV it causes aging and deterioration. During the storage, transport and marketing it affects the quality and freshness of FFV. There are technologic solutions for eliminating the ethylene gas accumulating in storage atmosphere probl ...Daha fazlası

Audiometer device design with integration of different sources = Farklı kaynaklara entegre işitme cihazı tasarımı

Uzun, Yiğit Ömer

Audiometry is the technique to identify the nature of hearing loss and to determine the threshold of hearing by recording responses of the patient after presenting him with auditory stimuli with varying intensity levels. There are different audiometric techniques and procedures used for achieving this. The vast majority of medical devices found in the marketplace as a commercial product for the field of audiology have been developed for clinical limited testing. These devices cannot be used for purposes other than those specified by the manufacturer. This has serious limitations in the experim ...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

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 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
