A constitutive model for hysteresis: the continuum damage approach for filled rubber-like materials
(Springer, 2020)
In this contribution, a constitutive model is proposed for filled rubber-like materials to describe hysteresis. The model is based on the network decomposition concept. Rubber matrix is decomposed into purely elastic and ...
New proposal for size and size-distribution evaluation of nanoparticles synthesized via ultrasonic spray pyrolysis using search algorithm based on image-processing technique
(Mdpi, 2020)
Nanoparticle properties are correlated to their size, size distribution, and shape; it is essential to accurately measure these features in the field of nanoscience. In this study, silver nanoparticles (AgNPs) were synthesized ...
Fabrication and characterization of Yb-doped Y2O3 powders and thin films
(Carl Hanser Verlag, 2020)
Yttrium oxide (Y2O3) and ytterbium (Yb)-doped Y2O3 particles were synthesized via the sol-gel method from the aqueous solution of their nitrate salts. The synthesized powders were then deposited on Corning glass substrates ...
Cutting performance improvement of MTCVD coated cemented carbide inserts via appropriate heat treatment
(Elsevier, 2020)
The softening of cemented carbide at the elevated temperature of MTCVD processes results in significant reduction of their strength, and thus, high coating deformation during cutting. In this way, at interrupted cutting ...
Investigation of temperature effect on the electrical properties of MWCNTs/epoxy nanocomposites by electrochemical impedance spectroscopy
(Taylor & Francis Ltd, 2020)
This study investigates the impact of the temperature exposure on the electrical properties of the multi-walled carbon nanotubes (MWCNTs)/epoxy based nanocomposites for the temperature range from 20 degrees C to 80 degrees ...
A general approach to halloysite clay mineral
(Nova Science Publishers, Inc., 2020)
Halloysite is a natural clay mineral that belongs to the kaolin group. Its chemical formula is Al2(OH)4Si2O5.nH2O. When n is equal to 2, it is hydrated, and when n is equal to 0, the halloysite is dehydrated. Generally, ...
A hyperelastic constitutive model for rubber-like materials
(Springer, 2020)
Hyperelastic behavior of isotropic incompressible rubbers is studied to develop a strain energy function which satisfies all the necessary characteristic properties of an efficient hyperelastic model. The proposed strain ...
Amplification of brightness variability by active-region nesting in Solar-like stars
(Iop Publishing Ltd, 2020)
Kepler observations revealed that hundreds of stars with near-solar fundamental parameters and rotation periods have much stronger and more regular brightness variations than the Sun. Here we identify one possible reason ...
Development of a larval zebrafish infection model for clostridioides difficile
(Journal Of Visualized Experiments, 2020)
Clostridioides difficile infection (CDI) is considered to be one of the most common healthcare-associated gastrointestinal infections in the United States. The innate immune response against C. difficile has been described, ...
Sentiment analysis of turkish twitter data using polarity lexicon and artificial intelligence
(Springer Science and Business Media Deutschland GmbH, 2020)
Sentiment analysis is a process of computationally detecting and classifying opinions written in a piece of writer’s text. It determines the writer’s impression as achromatic or negative or positive. Sentiment analysis ...
