Neimark-Sacker bifurcation and stability analysis of a discrete-time prey-predator model with Allee effect in prey
(SPRINGEROPEN, 2019)
In this paper, the dynamical behaviors of a discrete-time prey-predator model with Allee effect on the prey population are investigated. The existence and topological classification of the fixed points of the model are ...
Ultrasonic testing to measure the stress statement of steel parts
(Korean Society of Mechanical Engineers, 2019)
This paper presents an efficient method for stress measurement propagation. Pulse-echo method are used as stress measurement method on railway wheels. Hard service conditions and brake failures can lead to dangerous stress ...
High brightness ultraviolet light-emitting diodes grown on patterned silicon substrate
(ELSEVIER SCI LTD, 2019)
We report on the fabrication of high brightness AlGaN-based ultraviolet light emitting diodes (UV-LED) on patterned silicon. Using the lateral epitaxial overgrowth approach, we demonstrate the growth of a 6 mu m thick AIN ...
The Effect of Ozone Gas on IL-1? and IL-10 Levels of Gingival Crevicular Fluid in Aggressive Periodontitis Patients
(Taylor and Francis Inc., 2019)
Although the use of ozone therapy in dentistry has become widespread, the number of controlled clinical trials evaluating its effectiveness in periodontal therapy is limited. The aim of this study was to evaluate the ...
Geology of the Central Sivas Basin (Turkey)
(TAYLOR & FRANCIS LTD, 2019)
This paper presents a revised geological map at the 1/50,000 scale of the Central Sivas Basin together with a synthetic stratigraphic chart and cross-sections. The map covers an area of approximately 9840 km (2) within the ...
The Effect of Music on Auditory Hallucination and Quality of Life in Schizophrenic Patients: A Randomised Controlled Trial
(TAYLOR & FRANCIS INC, 2019)
The study was conducted to determine the effects of music on auditory hallucination and quality of life in schizophrenic patients. The sample of this randomised controlled study consisted of 28 patients (14 experimental ...
Position-dependent mass effects on the optical responses of the quantum well with Tietz-Hua potential
(ELSEVIER GMBH, 2019)
In the present study we have investigated the bound energy levels and intersubband optical transitions in the Tietz-Hua quantum well for a spatially varying effective mass distribution. The energy levels and eigenfunctions ...
The effects of spacing patterns on incidental L2 vocabulary learning through reading with electronic glosses
(SPRINGER, 2019)
This study investigates the impact of spacing on L2 incidental vocabulary learning. The participants divided into three groups studied the same 20 target words, which occurred nine times in 36 short reading texts in a ...
Developing a new and simple natural deep eutectic solvent based ultrasonic-assisted microextraction procedure for determination and preconcentration of As and Se from rice samples
(Royal Society of Chemistry, 2019)
A novel, green, and rapid natural deep eutectic solvent (NADES)-based ultrasonic-assisted microextraction procedure (UAME) was developed for extraction of arsenic (As) and selenium (Se) from rice samples prior to their ...
The selection of the best olympic place for Turkey using an integrated mcdm model
(Growing Science, 2019)
Hosting Olympic Games is a significant opportunity for every country and her metropolitan cities. Olympics offer several benefits to the Host countries and cities such as introducing cultural assets of the country to the ...
