Antimicrobial and physical properties of chitosan films incorporated with turmeric extract
(Elsevier Science Bv, 2017)
In this study, the effects of turmeric extract incorporation on the antibacterialand physical properties of the chitosan films were evaluated. Turmeric containing chitosan-based film was produced with casting procedure and ...
Cation Effect on Slow Release from Alginate Beads: A Fluorescence Study
(Springer/Plenum Publishers, 2014)
In this study, spherical alginate beads containing pyranine (P-y) as a fluorescence probe were prepared by ionotropic gelation of a sodium alginate solution. The steady state fluorescence technique was used to study pyranine ...
Surfactant and metal ion effects on the mechanical properties of alginate hydrogels
(Elsevier Science Bv, 2016)
This paper addresses the controlled variation of the mechanical properties of alginate gel beads by changing the alginate concentration or by adding different surfactants or cross-linking cations. Alginate beads containing ...
Antimicrobial cerium ion-chitosan crosslinked alginate biopolymer films: A novel and potential wound dressing
(Elsevier Science Bv, 2017)
Wound dressings require good antiseptic properties, mechanical strength and, more trustably, natural material ingredients. Antimicrobial properties of cerium ions and chitosan are known and alginate based wound dressings ...
ECG feature extraction based on the bandwidth properties of variational mode decomposition
(Iop Publishing Ltd, 2016)
It is a difficult process to detect abnormal heart beats, known as arrhythmia, in long-term ECG recording. Thus, computer-aided diagnosis systems have become a supportive tool for helping physicians improve the diagnostic ...
Phononic crystal surface mode coupling and its use in acoustic Doppler velocimetry
(Elsevier Science Bv, 2016)
It is numerically shown that surface modes of two-dimensional phononic crystals, which are Bloch modes bound to the interface between the phononic crystal and the surrounding host, can couple back and forth between the ...
Sharp bends of phononic crystal surface modes
(Iop Publishing Ltd, 2015)
Sharp bending of surface waves at the interface of a two-dimensional phononic crystal (PnC) of steel cylinders in air and the method of using a diagonally offset cylindrical scatterer are numerically demonstrated by ...
Subthreshold Photocoagulation, Laser Endpoint Management Based on Optical Coherence Tomography Angiography in Cases of Diabetic Macular Edema Refractory to Anti-VEGF
(Thieme, 2022)
Purpose: This study aimed to determine the changes that occur in the vasculature, as based on optical coherence tomography angiography (OCTA) after non-damaging endpoint management (EpM), using a continuous wave yellow ...
Detection of the separated root canal instrument on panoramic radiograph: a comparison of LSTM and CNN deep learning methods
(British Institute of Radiology, 2023)
Objectives: A separated endodontic instrument is one of the challenging complications of root canal treatment. The purpose of this study was to compare two deep learning methods that are convolutional neural network (CNN) ...
