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
ABSTRACTIn this study, the effect of a new generation bio-polymeric admixture on the physical and mechanical properties of cement mortars is examined in detail. The bio-polymeric admixture is prepared by grinding egg shells, apricot kernel shells, hazelnut kernel shells, walnut kernel shells, and olive seeds in micronized sizes. The evaluation of the bio-polymeric admixtures, which are produced as wastes, among high production materials such as concrete and mortar derivative products, provides an opportunity for better disposal and management of these wastes.ÖZETBu çalışmada, yeni nesil biyopo ...Daha fazlası
ABSTRACTEnergy has become one of the main problems of humanity after the industrial revolution and the rapid rise in world population. Most energy resources depend on fossil fuels, which causes environmental problems. Solar energy is a clean and sustainable alternative to the increasing world energy demand. In this context, perovskite solar cells (PSCs) are particularly attractive due to ability to achieve very high efficiencies. The power conversion efficiency (PCE) of PSCs has rapidly grown from 3.8 in 2009 to over 25.5 in 2022, which making it fastest advancing solar cell technology to date ...Daha fazlası
ABSTRACTThe rapid development of robot technology has started to be emphasized medical robotics increasingly. The potential of robotic systems to facilitate the work of healthcare workers, minimize human errors, restore function to lost limbs, and enable operations that cannot be performed due to distance or other factors have made this field increasingly popular.Surgical robotics applications are the trend subfield of medical robotics. In these applications, it is aimed to reach the desired task with certain precision and accuracy. Therefore, performance of the control system is very crucial ...Daha fazlası
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
ÖZETYapılarda kullanılmakta olan pencere, kapı ve diğer bir çok üründe, farklı malzeme özelliklerinin bir araya getirildiği yenilikçi hibrid ürün arayışları yer almaktadır.

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
ABSTRACTCopper is one of the most conductive metallic materials. For most metals, additive manufacturing is prone to laser or electron beam powder bed fusion processes. Due to copper's high reflectivity and very high thermal conductivity, it is difficult to print 3D parts with powder bed fusion methods. Binder jetting, which is a developing 3D printing technology, has a high potential for use in order to eliminate these problems of copper and low processing costs. In this study, the effect of particle size distributionand oxygen level of the copper powders on part density, tensile strength, su ...Daha fazlası
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
ABSTRACTAlthough gastronomy has always been a significant component of tourism products and tourist experience, with the changing tourist motivations and tourism trends gastronomy tourism has developed as a major type of alternative tourism all around the world since the 90s. Today, gastronomic values of the destinations attract many tourists and governments pay importance to gastronomy tourism as a tool in increasing for their tourism incomes. Social media is a digital platform that make individuals able to digitally interact with each other based on their interests. It has modified the way o ...Daha fazlası
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
