A heat transfer problem with exponential memory and the associated thermal stresses
(Wiley, 2022)In this study, a heat transfer problem defined by the Caputo-Fabrizio derivative, which is known to behave by the exponential decaying law, is addressed in an axially symmetric cylindrical region. Thus, the fundamental ... -
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
