Some fixed-disc results in double controlled quasi-metric type spaces
(MDPI, 2022)In this paper, we introduce new types of general contractions for self mapping on double controlled quasi-metric type spaces, where we prove the existence and uniqueness of fixed disc and circle for such mappings. -
A novel and simple approach to element fractionation analysis: Single step fractionation of milk
(Elsevier Sci Ltd, 2022)A novel single step fractionation of cow's milk was achieved using ethyl ether, n-hexane and isopropyl alcohol (3:3:4) mixture via solubility difference and precipitation. Milks were separated into lipid, serum and protein ... -
Using optimization method for determining lactic acid bacteria counts in white cheese with different salt concentrations
(Wiley, 2022)Total lactic acid bacteria, Lactococcus spp., yeast, and mold counts in white cheese were determined during 55 days of storage in brine solutions with 4%, 6%, 8%, 10%, 12%, 14%, and 16% (w/v) salt concentrations at 4 degrees ... -
Improvement of the saturation magnetization of PEG coated superparamagnetic iron oxide nanoparticles
(Elsevier, 2022)Polyethylene glycol (PEG) coated iron oxide nanoparticles are of interest because of their distinctive properties and potential applications such as magnetic resonance imaging, magnetic hyperthermia and drug delivery. In ... -
Forest fire causes and motivations in the southern and South-Eastern Europe through experts' perception and applications to current policies
(MDPI, 2022)Forest fires causes and motivations are poorly understood in southern and south-eastern Europe. This research aims to identify how experts perceive the different causes of forest fires as defined in the classification ... -
Mathematical modelling and gas sensing abilities of graphene based optical sensor
(Natl Inst Optoelectronics, 2022)In this work, graphene based Langmuir-Blodgett (LB) thin films prepared onto gold-coated glass substrates to evaluate its sensing ability by using Surface Plasmon Resonance (SPR) system. In order to illuminate the swelling ... -
The bisbenzothiazole-p-tert-butylcalix[4]arene-thiourea Langmuir-Blodgett thin films: preparation, optical properties, swelling dynamics and gas sensing properties via host-guest principles
(Springer, 2022)Calix[4]arene-based materials have been investigated to develop selective, sensitive, and low cost chemical sensors due to their simple, low cost synthesis, and wide range of chemical and physical properties. In this ... -
Julia and Mandelbrot Sets of transcendental function via Fibonacci-Mann iteration
(Hindawi Ltd, 2022)In this paper, utilizing the Fibonacci-Mann iteration process, we explore Julia and Mandelbrot sets by establishing the escape criteria of a transcendental function, sin(z(n )) + az + c, n >= 2; here, z is a complex variable, ... -
Determining effective environmental factors and ecology of non-marine Ostracoda (Crustacea) in Giresun, Turkey
(EDP Sciences, 2022)To determine influential environmental factors on ostracod species, 105 aquatic sampling sites were sampled from the Giresun province. Sixteen species collected from 69 sites are new records for the study area. Seven of ... -
Schiff base functionalized silica gel for simultaneous separation and preconcentration of cu(II), ni(II), and cd(II) in pharmaceuticals and water samples
