Performance evaluation of ejector with different secondary flow directions and geometric properties for solid oxide fuel cell applications
(Elsevier, 2019)
The mixing chamber length, secondary flow tube inclination angle, diffuser length and diverging angle as well as the direction of secondary flow on the ejector performance are numerically studied. The numerical results of ...
3Bio-Based Additives to Improve Diesel Engine Performance and Emissions
(Chinese Soc Mechanical Engineers, 2019)
This study investigates addition of ethanol and diethyl ether into diesel fuel. Base fuel and three different blends were used in the tests. The experiments were performed at engine speed of 1500 rpm and under various loads ...
Psychrotolerant bacteria isolated from the leaf apoplast of cold-adapted wild plants improve the cold resistance of bean (Phaseolus vulgaris L.) under low temperature
(Academic Press Inc Elsevier Science, 2019)
We have isolated psychrotolerant bacteria from the leaf apoplast of cold-adapted wild plants and aimed to investigate their effect on the cold resistance of bean (Phaseolus vulgaris L.). Based on the findings of 16S rRNA ...
Ohmic heating assisted hydrodistillation of clove essential oil
(Elsevier, 2019)
Ohmic heating assisted hydrodistillation is a novel green technology for the extraction of essential oils. In this study, clove bud essential oils (CEO) were extracted by ohmic heating assisted hydrodistillation (OAHD) and ...
Enhancing of the nonlinear absorption and optical limiting performances of the phthalocyanine thin films by adding of the single walled carbon nanotubes in poly(methyl methacrylate) host
(Elsevier, 2019)
Unlike the earlier nonlinear optical studies of single walled carbon nanotubes (SWCNTs) which were generally carried out as solvent, in this study, we established to deposit the unsoluble SWCNTs as homogeneous thin films ...
The in situ natural radionuclide (U-238,Th-232 and(40)K) concentrations in Gumuhane granitoids: implications for radiological hazard levels of Gumuhane city, northeast Turkey
(Springer, 2019)
We have carried out 48 in situ measurements on radioactivities of U-238, Th-232 and K-40 isotopes at the Gumuhane granitoid plutons employing gamma-ray spectrometer with a NaI(Tl) scintillation detector. The radionuclide ...
Estimating the number of clusters in a dataset via consensus clustering
(Pergamon-Elsevier Science Ltd, 2019)
In unsupervised learning, the problem of finding the appropriate number of clusters-usually notated as k- is very challenging. Its importance lies in the fact that k is a vital hyperparameter for the most clustering ...
Water soluble chitosan-caffeic acid conjugates as a dual functional polymeric surfactant
(Elsevier Science Bv, 2019)
A water soluble chitosan-caffeic acid conjugate (C-CAC) was prepared by chemical modification of chitosan using activated caffeoyl with dimethyl aminopyridine as a catalyst. The C-CAC was characterized using UV-visible ...
Jurassic acidic magmatism in a back-arc setting, eastern Sakarya Zone, Turkey: Geochemical constraints and an evolutionary model
(Elsevier, 2019)
The Early Jurassic in the Sakarya Zone, Turkey, was dominated by basic magmatism. The products of this magmatic episode are found as basaltic lavas and pyroclastic rocks in the Senkoy Formation, which was deposited in an ...
Natural Convection in an Enclosure with a Pair of Discrete Heat Sources
(Amer Inst Aeronautics Astronautics, 2019)
An experimental and numerical study is carried out to investigate natural convection cooling characteristics of discrete heat sources in a rectangular enclosure. One of the sidewalls of the enclosure is heated by a pair ...
