Development and Characterization of Peptide Modified Bioactive Membrane for Regeneration of Corneal Endothelial Tissue

Gülşah Sunal

Because of the drawbacks related with the current corneal transplantation techniques such as donor shortage, rejection or disease transmission risk, there is still an urgent requirement in order to produce new treatments for regenerating corneal tissue. Specially, it is also necessary to overcome the problems related with the blindness and vision losses originating from damage to corneal endothelium. By considering these, corneal tissue engineering might possess an encouraging potential to ensure alternative and innovative approaches toward the development of effective corneal tissue equivalen ...Daha fazlası

Design and Development of a Compound Mobile Serial Robot with Remote Control Application

Alpay Toprak

The design of a compound mobile serial robot controlled remotely by a C# program utilizing the MQTT (Message Queuing Telemetry Transport) protocol is the main topic of this thesis. The robot is powered by a Raspberry Pi. The advantages of mobility and serial manipulators are combined in the compound mobile serial robot, allowing it to carry out difficult tasks in a variety of settings. As the main computer, the Raspberry Pi gives the robot and its control application connectivity and processing capability. Data interchange and command execution are made possible by the integration of the MQTT ...Daha fazlası

Effect of Sediment Load on the Time Evolution of the Morphology of a Large-scale Laboratory Movable-bed Symmetrical Confluence

Zehra Büyüker

Akarsu kavşakları doğal drenaj ağlarının temel unsurları olup oluşturdukları habitat yüksek ekolojik değer arz etmektedir. Yan kollardaki sediment yükü ve akım arasındaki etkileşim kavşak morfolojisini düzenleyen önemli bir faktördür. Yan koldan gelen sediment yükü ve debinin ana kanal boyunca yer yer oyulmalara ve yığılmalara sebebiyet verdiği, bunların sonucunda da taban topoğrafyasında zamana bağlı değişimlerin olduğu gözlemlenmektedir. Bu çalışmada İzmir Kâtip Çelebi Üniversitesi Hidrolik Laboratuvarında bulunan, simetrik iki yan kolun 90˚ açı ile ana kanala bağlandığı açık kanal kavşağı ü ...Daha fazlası

Citizen Design Science in the Context of Crowd-Creative Design Practices: Case of Izmir

Pelin Özden

Citizen Design Science is the new co-design strategy for urban systems through active design tools with the help of citizens' observation, experience, and local knowledge, which improves the planning, design, management, and regeneration of cities, urban living spaces, public spaces, and buildings. The approach combines the opportunity of crowdsourcing ideas, concerns, and knowledge by citizens on urban spaces. Urban planning and design need to be human-centered by understanding citizens’ experiences, concerns, and wishes for urban spaces. In the resilient city target, it is important t ...Daha fazlası

Dynamics of Axisymmetric Drops Impacting onto Heterogeneous Surfaces

Atalay SEÇER

The way a droplet behaves when it lands on a surface depends on the characteristics of the surface and the flow conditions of the droplet. It can deposit, rebound, splash, etc. There is delimited research on how surface roughness and chemical composition affect the deformation of droplets upon impact, in comparison to the studies done on smooth surfaces. Our model uses two-phase flow to simulate the axisymmetric motion of droplets over surfaces with heterogeneities by combining the Navier-Stokes equations for motion with the Cahn-Hilliard equation for tracking the phase-field. We integrate the ...Daha fazlası

Controlling the Motion of Capillary Driven Interfaces in Channels with Chemical Heterogeneity

Mehmet Alptuğ Boylu

The use of self-driven fluids (e.g., droplets, capillary flows) attracts many researchers as the external driving mechanisms are diminished or eliminated. The contact angle hysteresis generates a driving force (a pressure difference across interfaces). This pressure depends on the interaction with the solid substrates and is controlled if one varies the surface energy of the walls. Self-transport and manipulation of interfaces play an important role in the development of microfluidic devices, self-cleaning, water harvesting and heat transfer enhancement. In this study, we search for the effect ...Daha fazlası
