The tourism industry is referred to as the world’s one of the largest serviceindustries and as one way to achieve development in tourism destinations across the globe and offering benefits and contributing to the local economy for any country. Tourism, which becomes a common phenomenon and important for a wide range of reasons, particularly for the developing countries is one very sensitive and fragile industry to any negativity by its nature. In the global economy, the share of the tourismindustry is increasing and thus, intensifying competition among the growing number of tourism destination ...Daha fazlası
ÖZETKurşun asit akü elektrotlar, kurşun oksidin sülfürik acid ile karıştırılmasıyla elde edilir. İlaveten, bazı karbon türevleri ve bazı polimer fiberler, aktif malzeme etkinliğini arttırmak ve plakaların mukavemetinin arttırılması için pastaya eklenir. Onlarca yıldır, birçok araştırmacı tarafından akülerin şarj olma kabiliyetini arttırmak için çeşitli karbon türevleri aktif katkı malzemesi olarak çalışılmıştır. Karbon bakımından zengin yüzeyler aktif malzemede iletken bir köprü oluştururken aynı zamanda yüzeyin elektrokimyasal etkinliğini de arttırır. Bu nedenle, aktif malzeme içine karbon il ...Daha fazlası
ABSTRACTThroughout the human life, neurological disorders can occur in body areas due to accidents or other biological factors, which negatively affects human life by destroying nerve commands. In these scenarios, continuous and efficient exercises that focus on injured extremities have great benefits in regaining functional losses by retraining motor movements. Rehabilitation procedures need to be applied quickly in order to create neural plasticity and regain affected motor functions. Although theseactions are mostly performed by therapists in current rehabilitation procedures, robotic rehab ...Daha fazlası
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
ABSTRACTCarbonaceous materials have attracted a tremendous amount of attention during the last decades due to their outstanding properties for a variety of applications. Among them, carbon fibers are state of the art materials with excellent physical, mechanical, electrical, thermal and chemical properties. Especially the thermal and electrical properties of carbon fibers combined with other prominent characteristics enable them to be employed as an effective heating element. Regarding to this motivation, in this study, it is mainly aimed to fabricate carbon fiber based heating elements and to ...Daha fazlası
ABSTRACTSquamous cell carcinoma (SCC) is the second most seen type of non-melanoma skin cancers after basal cell carcinoma (BCC). Prevalence of non-melanoma skin cancer increases rapidly and it’s expected to account for 50 of all cancer types in near future. It takes attention and carries importance due to higher risk of metastasis. Even though various methods are being used, those methods may either fall short or cause serious side effects. Plasma is defined as the fourth state of matter and cold atmospheric plasma (CAP) can be produced at atmospheric pressure under high electrical field. The ...Daha fazlası
ABSTRACTNervous system diseases occupy a very large place among diseases without treatment today. One of the major challenges in nervous system diseases is achieving functional connection between nerve cells. A neuronal network is a very complex structure consisting of connections between neuronal cells through dendrites and axons. In this context, a human brain can be described as a complex neuron network. Platforms capable of creating a neuronal network have the potential to be used in a variety offields, such as modeling neuron-related diseases, finding new treatments, building biological c ...Daha fazlası
ÖZETPaslanmaz çelik içi boş fiber membranlar, çevre, kimya ve atık arıtma endüstrilerinde gaz ve sıvı ayrıştırmaları veya partikül filtresi olarak kullanılır. Seramik içi boş fiberlerin yük kapasitesi ve kırılganlığı bu uygulamalar için bir sorundur. Son 5 yılda özellikle paslanmaz çelik membranlarla ilgili çalışmalar artmış ve 300 MPa ve üzeri eğilme mukavemetine, iyi gaz geçirgenliğine ve filtrasyon performansına sahip malzemeler üretilmiştir. Bu tezin amacı, farklı toz boyutlarında, kompozit içeren farklı kompozisyonlarda ve farklı sinterleme atmosferlerinde (argon ve azot/hidrojen) içi boş ...Daha fazlası
ABSTRACTIn this thesis, the economic analysis of water storage by rainwater harvesting technique at Izmir Katip Celebi university (IKCU) was studied. The data from the flowmeters, which were installed in the men-women toilets in the central classrooms, were recorded, and the catchment area was calculated. According to the data, the amount of rainwater to be collected can meet the water demand in the toilets flushing. Theeconomic analysis of the rainwater harvesting (RWH) was made for three scenarios their difference in initial cost by the calculations of the payback period (PBP), the net prese ...Daha fazlası

ABSTRACTPC12 cell line is widely used as an in vitro model for neuronal diseases and studying cell differentiation behavior. The cell line has the ability to differentiate into neuronlike cells in the presence of nerve growth factor (NGF), resulting in neural extensions called dendrites and axons. Cell patterning is widely used in applications such as neuron network formation, tissue engineering, and cell based biosensors. In this study, the effect of randomly distributed and aligned multi walled carbon nanotubes (MWCNTs) in poly(ethylene glycol) dimethacrylate (PEGDMA) on PC12 cell neuronal d ...Daha fazlası
