Theoretical investigation on combustion characteristics of ethanol-fueled dual-plug SI engine
(Elsevier Sci Ltd, 2019)
In this study, effects of equivalence ratio, spark timing and spark plug number and locations on combustion characteristics were theoretically investigated using an ethanol-fueled dual-plug SI engine. Two-zone quasi-dimensional ...
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 ...
Addressing the sneak-path problem in crossbar RRAM devices using memristor-based one Schottky diode-one resistor array
(Elsevier, 2019)
Resistive random access memories (ARAMs) are favorable contenders in the race towards future technologies. Moreover, the desirable properties of memristor-based RRAM devices make them very good competitors in this field. ...
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 ...
ON SOME PROPERTIES OF HYPER-BESSEL AND RELATED FUNCTIONS
(Turkic World Mathematical Soc, 2019)
In this study, by using the Hadamard product representation of the hyperBessel function and basic concepts in mathematics we investigate the sign of the hyperBessel function x -> J alpha(d) (x) on some sets. Also, we show ...
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 ...
The inhibition profile of sesamol against alpha-glycosidase and acetylcholinesterase enzymes
(Taylor & Francis Inc, 2019)
Sesamol (1,3-benzodioxol-5-ol) is found in the oilseed product, sesame. In our study, the inhibitory effects of sesamol compound on acetylcholinesterase and alpha-glycosidase enzymes were evaluated. Another aim of this ...
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 ...
