The effects of STEM activities on the problem-solving skills of 6-year-old preschool children
(Routledge Journals, Taylor & Francis Ltd, 2021)
In this study, the effects of STEM activities on the problem-solving skills of preschool children were investigated. A two-group (study: n = 18 and control: n = 18) pre-test/post-test/retention test experimental design was ...
Heat transfer of brake pad used in the autos after friction and examination of thermal tension analysis
(2014)
As a result of the friction of brake pads which is one of the factors affecting automobile performances with brake disc, heat energy comes into being. This heat energy causes brake pads to expose to excessive temperature. ...
PT symmetric Floquet topological phase in SSH model
(Elsevier Science Bv, 2018)
We consider periodically modulated Su-Schrieffer-Heeger (SSH) model with gain and loss. This model, which can be realized with current technology in photonics using waveguides, allows us to study Floquet topological ...
Dynamics of a Second-order System of Nonlinear Difference Equations
(Semnan Univ, 2020)
In this paper, we investigate the equilibrium points, stability of two equilibrium points, convergences of negative equilibrium point, periodic solutions, and existence of bounded or unbounded solutions of a system of ...
Dynamical analysis of a non-linear difference equation
(Eudoxus Press, LLC, 2019)
In this article, we investigate the dynamics of the solutions of the following non-linear difference equation xn+1 = xn-2xn-3 - 1; n ? ?0 with arbitrary initial conditions x-2; x-1; x0. Besides, we have studied peri- odic ...
Analysis of polyacrylonitrile nanofiber yarn formation in electrospinning by using a conical collector and two oppositely charged nozzles
(Taylor & Francis Ltd, 2021)
Nanofiber production by electrospinning has become a common production method as it is an easy and flexible system producing nanofibrous webs. However, direct spinning of nanofibers into a yarn would lead to conversion of ...
Evaluation of Relationship between Obsessive-compulsive Disorder and Dissociative Experiences
(Korean Coll Neuropsychopharmacology, 2018)
Objective: The aim of the study is to evaluate the relationship between obsessive-compulsive disorder (OCD) symptoms and dissociative experiences and the effect of childhood traumatic experiences on this relationship in ...
Bisphosphonic Acid-Functionalized Cross-Linkers to Tailor Hydrogel Properties for Biomedical Applications
(Amer Chemical Soc, 2018)
Two bisphosphonic acid-functionalized cross-linkers (one novel) with different spacer chain characteristics were synthesized and incorporated into hydrogels by copolymerization with 2-hydroxyethyl methacrylate at different ...
Social support and postpartum depression in low-socioeconomic level postpartum women in Eastern Turkey
(Springer Basel Ag, 2010)
The aim of this article was to determine risk factors for postpartum depression in low-socioeconomic level women during the first postpartum year and to determine the relationship between postpartum depression symptoms and ...
Artificial neural network-based 4-d hyper-chaotic system on field programmable
(Ismail Saritas, 2020)
In this presented study, a 4-D hyper-chaotic system newly proposed to the literature, has been implemented as Multi-Layer Feed-Forward Artificial Neural Network-based on FPGA chip with 32-bit IEEE-754-1985 floating-point ...
