DENSITY AND FINITENESS RESULTS ON SUMS OF FRACTIONS
(AMER MATHEMATICAL SOC, 2019)
We show that the height density of a finite sum of fractions is zero. In fact, we give quantitative estimates in terms of the height function. Then, we focus on the unit fraction solutions in the ring of integers of a given ...
Investigation of the reliability of light-curing units in Sivas City, Turkey
(WOLTERS KLUWER MEDKNOW PUBLICATIONS, 2019)
Background: The number of studies investigating the physical properties of light-curing units used in city centers in terms of the light intensity, presence of residues fractures at the tips, how long they have been used, ...
Comparison of microtensile bond strength and resin-dentin interfaces of two self-adhesive flowable composite resins by using different universal adhesives: Scanning electron microscope study
(WILEY, 2019)
The aim of this in-vitro study was to evaluate microtensile bond strength (mu TBS) of two different self-adhesive composites (SACs) on the permanent dentin by applying five different universal adhesive systems. In this ...
Computational Analysis of Heat and Mass Transfer of Impinging Jet onto Different Foods during the Drying Process at Low Reynolds Numbers
(PLEIADES PUBLISHING INC, 2019)
In the present work, heat and mass transfer from different foods by impinging a slot hot air jet at low Reynolds numbers is numerically researched. Banana and apples are selected as foods due to their trading importance. ...
Approximation of the integral funnel of the Urysohn type integral operator
(ELSEVIER SCIENCE INC, 2019)
The integral funnel of the closed ball of the space L-p, p > 1, with radius r and centered at the origin under Urysohn type integral operator is defined as the set of graphs of the images of all functions from given ball. ...
The effect of an N- heterocyclic compound on corrosion inhibition of J55 steel in sweet corrosive medium
(ROYAL SOC CHEMISTRY, 2019)
The corrosion inhibition behavior of a naphthoxazinone derivative 1-phenyl-1,2-dihydronaphtho[1,2-e][1,3]oxazin-3-one (PNO) on J55 steel in 3.5 wt% NaCl solution saturated with carbon dioxide was evaluated using weight ...
Hybrid Band Combination for Discriminating Lithology of Dunite in Ultramafic Rocks
(SPRINGER, 2019)
In recent years, satellite image and other data provided by the terrestrial component of remote sensing technology have been used for detecting hydrothermal alteration minerals and regional geology mappings. Existing rock ...
Nonlinear dynamic response of a tall building to near-fault pulse-like ground motions
(SPRINGER, 2019)
The objective of this study is to determine the effects of near-fault ground motions with large, medium and small pulse periods on a core-wall tall building. Three near-fault and one far-field ground motion sets, each with ...
Magnetic, monodisperse titania microspheres with bimodal pore size distribution by a new sol-gel templating method and their photocatalytic activity
(SPRINGER, 2019)
A new sol gel templating method was developed for the synthesis of magnetic monodisperse-porous titania microspheres 5.5 mu m in size. A bimodal pore size distribution including both mesoporous and macroporous regions was ...
Synthesis of tetra-substituted phthalocyanines bearing 2-(ethyl(m-tolyl) amino)ethanol: Computational and photophysicochemical studies
(ELSEVIER SCIENCE SA, 2019)
This work presents the synthesis of 4-(2-(ethyl(m-tolyl) amino) ethoxy) phthalonitrile (1) as ligand and its peripherally tetrasubstituted metal-free (2) and metallophthalocyanines (3-5) derivatives. Synthesized compounds ...
