Neurovascular Co-Cultures in hydrogel building blocks Hidrojel bloklarda nörovasküler ko-kültür çalışmaları

Ersoy, Fulya

ABSTRACTCreating a tissue or an organ model is the most emerging field of the biomedical research for the last decades. Three-dimensional scaffolds that will mimic the extracellular matrix were designed and used in various applications to investigate the behavior of cells.In this study, both the synthesis of the polymer and the fabrication of three-dimensional hydrogel scaffolds were practiced. Gelatin methacrylate (GelMA) was synthesized prior to photopolymerization of the hydrogel. A novel scaffold fabrication device was designed and manufactured. This device allowed us fabricating computer ...Daha fazlası

Investigations of mechanical and flammability properties of hdpe reinforced flame retardant additives including antimony trioxide Antimon trioksit içeren alev geciktirici katkılı yüksek yoğunluklu polietilen’in mekanik ve alevgeciktiricilik özelliklerinin incelenmesi

Engin, Berk

ÖZETGünümüzde, Yüksek Yoğunluklu Polietilen (HDPE)’nin, kimyasal direnç, kolay üretim tekniği, termal ve elektriksel yalıtımı, yüksek mukavemet/yoğunluk oranı gibi özelliklere sahip olmasından olayı yaygın bir kullanım alanı mevcuttur. Ancak HDPE, içerdiği karbon ve hidrojenden dolayı son derece yanıcıdır, HDPE'nin yangına karşı dayanıklılığını geliştirmek için uygulanabilecek bazı Alev Geciktirici takviye işlemlerivardır. Bu çalışmada Antimon Trioksit (Sb2O3) içeren iki farklı tipte ticari AlevGeciktirici masterbatch belli oranlarda HDPE matrise takviye edilmiştir. Bu şekilde HDPE matris örne ...Daha fazlası

Development of an effective kinematic synthesis and admittance control methodology for rehabilitation robotics Robotik rehabilitasyon için etkili bir kinematik sentez ve admitans kontrol yönteminin geliştirilmesi

Koçak, Mertcan

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

Assessment of direct and fluid mediated cold atmospheric plasma treatment efficacy on squamous cell carcinoma at three-dimensional skin culture model Direkt ve sıvı aracılı plazma muamele yöntemlerinin skuamöz hücreli karsinom üzerindeki etkinliğinin üç boyutlu deri kültür modelinde değerlendirilmesi

Özdemir, Gizem Dilara

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

Carbon based heating elements and their practical applications Karbon bazlı ısıtma elemanları ve pratik uygulamaları

Yavaş, Ahmet

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
