The design, manufacturing and applications of a novel led-based phototherapy device Yeni Bir LED tabanlı fototerapi cihazının tasarımı, üretimi ve uygulamaları

Yaşar, Büşra

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

Effect of particle size distribution modality of CaCO3 on sealing wide fractures using sepiolite muds CaCo3 parçacık boyut dağılım modalitesinin sepiyolit çamurları kullanılarak geniş çatlakların tıkanmasına etkisi

Tezcan, Meltem

SUMMARYLost circulation is defined as the invasion of naturally fractured and unconsolidated formations by the drilling fluid. Preventing loss circulation is a highly challenging problem while drilling a well. High loss circulation results in cost increase and well instability problems along with the contamination of productive formations. Lost circulation materials (LCMs) are used to prevent partial or total losses through pore throat and fractures. Special LCM treatments may be applied in the case of severe losses for wide fractures. However, the outcomes of all these efforts have not been l ...Daha fazlası

Biomechanics of acetabular fractures with low energy trauma via finite element modeling and analysis Düşük enerji travmalı acetabular kırıklarının sonlu elemanlar modeli ve analizi

SAMET ÇIKLAÇANDIR

The skeletal system undertakes many tasks such as the movement of the body, mineral storage, and protection of soft tissues. Damage to this structure affects human life negatively. Fractures that occur in the human body is damage to mainly to the bone structure and associated surrounding tissues. Therefore, it is necessary to understand how the fractures are formed and the fracture mechanism. Furthermore, the mechanism of fracture is complicated and worthy of investigation. However, the examination of the bone is difficult because it is a structure covered with tissues like veins and muscles. ...Daha fazlası

Estimation of emotional situation using EEG signals and machine learning methods EEG sinyalleri ve makine öğrenme yöntemlerini kullanılarak duygusal durum kestirimi

Yeşilkaya, Bartu

ÖZETEmotion estimation is an effective analysis method used to increase the interaction between humans and machines. Electroencephalogram (EEG) based emotion prediction studies based on brain signals become very attractive since they provide successful results of emotion analysis. In this study, new methods for emotion prediction are presented in accordance with dimensional emotion modeling. Multichannel EEG signals are recorded while the subjects viewed pictures from the International Affective Image System (IAPS) data set. Signal preconditioning and artefact elimination was performed by appl ...Daha fazlası

Simulation of three-dimensional slender droplet motion with adaptive mesh refinement Uyarlanabilir ağ yapısı ile üç boyutlu ince damla hareketi simülasyonu

Özdoğan, Mert

ABSTRACTWhile droplet moves over surfaces, various structures are observed cusp and corner formation, pearling, pinning/depinning, to name a few. We develop a finite element method (FEM) based solver to analyze three-dimensional motion of slender droplets over several substrates. To get accurate results within a feasible computation time, an adaptive mesh refinement (AMR) based on non-conformal, balanced and preload quadtree mesh structure is embedded within our quadratic FEM solver to focus our computational power on specific regions like contact lines. We validate our solver with the power-l ...Daha fazlası

Tattoo dye removal using cold athmospheric plasma (CAP) Soğuk atmosferik plazma (SAP) kullanarak dövme boyası silme

ELİF ÇUKUR

ABSTRACTTattoo has been used as a method of self-expression of mankind since ancient times. The tattoo removal process with primitive methods is based on the process of peeling the skin layer on which the tattoo is placed. Besides being used today, laser is preferred by more people. The tattoo removal with laser is based on disintegration into smaller pieces by breaking the target tattoo pigment by absorbing the transmitted beam. It is then transferred to the nearest lymph node or disintegrated by the macrophages by means of blood or lymph circulation. The most common difficulty with laser tat ...Daha fazlası

Development of novel donor and acceptor sam molecules for photovoltaic applications Fotovoltaik uygulamalar için yeni nesil donör ve akseptör kendiliğinden organize tek katman moleküllerin geliştirilmesi

Arkan, Emre

ABSTRACTSurface modification of indium tin oxide (ITO) is a crucial factor to alter the energy level barrier between ITO and perovskite that has direct influence on the charge extraction and recombination at interface. This henomenon has further direct effect on device parameters such as open circuit voltage (VOC), fill factor (FF), and short circuit current density (JSC). This study was base on the synthesis of six novel SAM molecules to be used in fabrication of p-i-n type perovskite solar cells. Since proposed SAMs are of push-pull type molecular nature, contiguous thiophene rings were used ...Daha fazlası
