The design, manufacturing and applications of a novel led-based phototherapy device Yeni Bir LED tabanlı fototerapi cihazının tasarımı, üretimi ve uygulamaları

Yaşar, Büşra

ABSTRACTJaundice is a very common disease in infants. It is caused by an increase in the level of bilirubin in the blood. Its incidence in newborns is around 60-70. When jaundice becomes pathological, it can cause much damage to the body: brain damage, vision loss, lung and kidney dysfunction, and even death. With the increase of bilirubin and its accumulation in the organs, irreversible damage occurs. There are different methods such as exchange transfusion, medication, and phototherapy to remove bilirubin from the environment. Blue light with a wavelength of 430-490 nm is required for light ...Daha fazlası

Coşkun, İhsan

ABSTRACTOsteomyelitis is a disease in which the process of bone destruction and loss is caused by microorganisms. Osteomyelitis has an increasing incidence rate that could cause chronic and acute infections. Bone infection has caused recurrent and permanent damage in 40 of the patients. 2-5 of infections caused by medical devices used in orthopedic surgical operations are osteomyelitis. More than half of osteomyelitis cases are caused by gram-positive bacteria such as Staphylococcus aureus and Staphylococcus epidermidis. In order to prevent the occurance of osteomyelitis due to the medical dev ...Daha fazlası

The effect of local heating on the weld line formation in plastic ınjection molding of acrylonitrile butadiene styrene and glass fiber reinforced polypropylene Akrilonitril bütadien stiren ve cam elyaf takviyeli polipropilenin plastik enjeksiyon kalıplamasında lokal ısıtmanın birleşme izi oluşumuna etkisi

Güler, Muhsin Deniz

ABSTRACTIn this study, the effect of local heating on the weld line formation in a plastic injection mold was studied by using acrylonitrile butadiene styrene (ABS) and polypropylene 20 glass fiber (PP GF20) plastic material. An aluminum 6000 insert was fitted into the injection mold to set temperatures for local heating. The three parameters with three levels were selected for injection molding process parameters as insert temperature, mold temperature, and melt temperature and to produce mechanical tests specimens with weld lines and non-weld lines. L9 orthogonal array was arranged for the T ...Daha fazlası

Detection of coal fires in soma with landsat temporal thermal images Landsat temporal termal görüntüleri ile Soma'da kömür yangınlarının tespiti

Köşker, Merve

ABSTRACTCoal is one of the most important energy resources used in many countries for decades to produce energy. A type of fire called coal fires occurs when the coal surface is exposed to sunlight and in contact with oxygen for a long time in coal mine areas where coal is extracted. Coal fires are prevalent and critical incidents for most coal mining areas around the world. Various problems arise due to coal fires in coal mines. These problems affect many factors such as environment, society, economy and security directly or indirectly. Burning coal fire causes the formation of poisonous gase ...Daha fazlası

Simulation of three-dimensional slender droplet motion with adaptive mesh refinement Uyarlanabilir ağ yapısı ile üç boyutlu ince damla hareketi simülasyonu

Özdoğan, Mert

ABSTRACTWhile droplet moves over surfaces, various structures are observed cusp and corner formation, pearling, pinning/depinning, to name a few. We develop a finite element method (FEM) based solver to analyze three-dimensional motion of slender droplets over several substrates. To get accurate results within a feasible computation time, an adaptive mesh refinement (AMR) based on non-conformal, balanced and preload quadtree mesh structure is embedded within our quadratic FEM solver to focus our computational power on specific regions like contact lines. We validate our solver with the power-l ...Daha fazlası

Production of dental filling composite material with ımproved mechanical and antibacterial properties by zno/chitosan doped silica/pmma core/shell nano hybrid structured ınorganic matrix ZnO/Kitosan katkılı silika/PMMA çekirdek/kabuk nano hibrit yapılı inorganik matris ile mekanik ve antibakteriyel özellikleri geliştirilmiş dental dolgu kompozit malzemesi üretilmesi

Ok, İzel

ABSTRACTOrganic-inorganic (hybrid) dental filling composite resins are becoming increasingly popular as a result of their aesthetic quality, good mechanical properties, optimum wear resistance, and ease of use. However, dental composites have relatively high brittleness, low strength, and durability, which limits applications. Dental filling composites containing nanoparticles have been developed in recent years to address the drawbacks of dental composites. These composites have high filling percentages and provide high strength and durability to the resin. However, the characteristics of the ...Daha fazlası

A vehicle routing problem based scenario analysis for optimum siting of municipal solid waste transfer stations Belediye katı atık aktarma istasyonlarının optimum yerleşimi için araç rotalama problemine dayalı senaryo analizi

Höke, Milas Ceren

ABSTRACTThe management of public services requires an in-depth decision-making method to provide the intended functionality and service life. Municipal solid waste management is indeed one of the most challenging tasks of local municipalities and currently occupies a substantial portion of the overall municipal expenses. In this study, an entirely geographic information system (GIS) based facility siting method is developed to aid governmental bodies in the decision-making process to site such facilities. The proposed method is applied to site a transfer station (TS) in the southeastern region ...Daha fazlası

Microwave sensor design for non-ınvasive blood glucose measurement Non-invaziv kan şekeri ölçümü için mikrodalga sensör tasarımı

Kuran, Mutahhar

ÖZETDiyabet izleme, kan şekeri monitörlerinin kullanılmasını gerektirir. Biyolojik dokunun dielektrik özelliklerinde glikoza bağlı değişimi algılayarak, RF yaklaşımlarının kan şekeri ölçümlerini sağlaması umut vericidir. Bu yaklaşım non-invaziv ve sürekli kan şekeri takibi sağlayabilir. Mevcut araştırmalar, kan şekeri monitörlerini invaziv olmayan bir şekilde ölçmek için elektromanyetik dalgalar kullanan bir monitörün geliştirilmesine odaklanmaktadır. Yöntem, bir izleme cihazının rezonans frekansını, glikoz seviyesi ile ilgili olan kanın geçirgenliği ve iletkenliği ile ilişkilendirir. Değişen ...Daha fazlası

The impacts of governance on tourism: a macro perspective Yönetişimin turizm üzerindeki etkileri: makro bir perspektif

Can, Yağmur

ABSTRACTIn this study, the effects of world governance indicators on tourism were empirically analysed, from the 2005 to 2018 period. A literature review for governance is included in the first part. The second part contains the definition of world governance indicators (WGI). In the last part, panel co-integration, and causality analysis have been carried out worldwide within 137 countries. As a result of the analysis, a long-run relationship was found only between the change in the number of tourists and the political stability - no violence index. Also, other world governance indexes voice ...Daha fazlası

Investigation of the adhesive-bonded aluminum-polyamide hybrid joints Yapıştırıcı ile birleştirilmiş alüminyum-poliamid hibrit bağlantıların incelenmesi

Batıkan Kandemir, Miray

ABSTRACTToday, environmentally friendly, high-strength and lightweight engineering materials are becoming increasingly important for the automotive and aviation industries. For this purpose, it is critical to combine different materials correctly and to create a reliable hybrid structure. Adhesives have a huge market share among the joining methods due to their low-stress concentration, high formulation possibility, good fatigue resistance, and sealing advantages. However, surface properties and surface treatments play an active role in determining joint performance. In this thesis, the effect ...Daha fazlası
