Experimental and Numerical Investigation of the Flexural Behavior of Reinforced-Concrete Beams Utilizing Waste Andesite Dust Korkut, Fuat; Karalar, Memduh; Motameni, Ali; Althaqafi, Essam; Özdöner, Nebi; Özkılıç, Yasin Onuralp (2024-09-01) During the process of cutting andesite stones, the waste mud is kept in powder form once fully dried. It is difficult to store the waste that is produced as a consequence of the extensive utilization area and consumption o...
Self-composite silk fibroin membranes for guided bone regeneration: 1 material 3 architectures with intrinsic integrity Atila, Deniz; Gürses, Senih; Tezcaner, Ayşen (2024-06-01) Silk fibroin (SF) takes attention in tissue engineering due to unique features, e.g., excellent biocompatibility/biodegradability with superior mechanical/thermal properties despite its lightweight. Guided bone regeneratio...
Effect of dynamic soil-structure interaction modeling assumptions on the calculated seismic response of railway bridges with single-column piers resting on shallow foundations İmamoğlu, Çağrı; Dicleli, Murat (2024-06-01) In this study, the effect of dynamic soil-structure modelling assumptions on the calculated seismic response of railway bridges with single column piers resting on shallow foundations is investigated. For this purpose, 10 ...
The effect of foot somatosensory loss in postural control during Functional reach test in patients with diabetic polyneuropathy: A controlled study Kahveci, Abdulvahap; Cengiz, Berat Can; Alcan, Veysel; Gürses, Senih; ZİNNUROĞLU, MURAT (2024-06-01) Background: In patients with diabetic polyneuropathy (DPN), differences in postural control due to losing the lower limb somatosensory information were reported. However, it is still unclear by which mechanisms the dynamic...
Methods to improve antibacterial properties of PEEK: A review Uysal, Idil; Tezcaner, Ayşen; Evis, Zafer (2024-03-01) As a thermoplastic and bioinert polymer, polyether ether ketone (PEEK) serves as spine implants, femoral stems, cranial implants, and joint arthroplasty implants due to its mechanical properties resembling the cortical bon...
VS Profiles for Turkey Şen, Ali Cemil; Ertuğrul, Zehra (2024-01-01) The Disaster and Emergency Management Authority of Turkey is currently operating 850 strong-motion stations throughout the country. At 112 of 850 station sites, variation of shear-wave velocity (VS) with depth was measured...
