A method proposal for monitoring the microclimatic change in an urban area
(ELSEVIER SCIENCE BV, 2019)
It is known that changes in urban surface characteristics lead to different urban climates. The surrounding environment directly affects thermal comfort and human behavior. In this respect, for sustainable urban growth, ...
Examination of Different Communication Topologies for Distributed Control of Multi-terminal HVDC Grids
(INT JOURNAL COMPUTER SCIENCE & NETWORK SECURITY-IJCSNS, 2019)
This paper discusses different communication topologies for cooperative distributed control design of a multi-terminal DC (MTDC) network. In the discussed architecture, the objective of the control design is the DC node ...
Investigations of structural, spectral, electronic and biological properties of N-heterocyclic carbene Ag(I) and Pd(II) complexes
(ELSEVIER SCIENCE BV, 2019)
Computational analyses of two Ag(I) and two Pd(II) complexes were done. Benchmark analyses were performed to obtain the most appropriate calculation level for studied complexes. HF, B3LYP and M062 x method were selected ...
Nonlinear Optical Rectification, Second and Third Harmonic Generations in Square-Step and Graded-Step Quantum Wells under Intense Laser Field
(IOP PUBLISHING LTD, 2019)
For square-step quantum wells (SSQWs) and graded-step quantum wells (GSQWs), the nonlinear optical rectification (NOR), second harmonic generation (SHG) and third harmonic generation (THG) coefficients under an intense ...
Determination of Paragliding Fields with GIS-based Analytic Hierarchy Process
(ISTANBUL UNIV, FAC LETTERS, DEPT GEOGRAPHY, 2019)
Nowadays, people living in the city tend to want to get away from the city. This situation is leading to an ever increasing interest in nature tourism and an orientation to outside sports. One of the most popular nature ...
Experimental and numerical investigation of impinged water jet effects on heated cylinders for convective heat transfer
(ELSEVIER FRANCE-EDITIONS SCIENTIFIQUES MEDICALES ELSEVIER, 2019)
Effect of jet flow structures impinged on a heated cylinder has been investigated experimentally and numerically in this study. The FLUENT 6.3.26 was used to simulate this numerical problem. In the numerical section, the ...
BIOLOGICAL EVALUATION OF 1-(4-(HYDROXY(1-OXO-1,3-DIHYDRO-2H-INDEN-2-YLI-DENE)METHYL)PHENYL)-3-PHENYLUREA DERIVATIVES: ANTICHOLINERGICS AND ANTIEPILEPTIC POTENTIALS
(PARLAR SCIENTIFIC PUBLICATIONS (P S P), 2019)
In this work, a class of phenylurea compounds containing 2-benzoylindan-1-one molecules 3a-3j was designed and synthesized from the reaction of phenylurea-substituted acetophenone compounds with phthalaldehyde molecule ...
Experimental determination of interfacial energy for solid Al in the Al-Sn-Mg eutectic system with Bridgman-type apparatus
(ELSEVIER SCIENCE BV, 2019)
The equilibrated grain boundary groove shape of solid Al in equilibrium with Al-Sn-Mg eutectic liquid was observed by using a Bridgman type directional solidification apparatus. The ratio of the thermal conductivity of the ...
Screening the in vitro antioxidant, antimicrobial, anticholinesterase, antidiabetic activities of endemic Achillea cucullata (Asteraceae) ethanol extract
(ELSEVIER SCIENCE BV, 2019)
The Achillea genus belongs to the Asteraceae family, which is mostly found in the northern hemisphere and is comprised of 115 species in the world. In Turkish flora, there are 52 species and 58 taxa, among them half of ...
Magnetic solid phase extraction of trace paracetamol and caffeine in synthetic urine and wastewater samples by a using core shell hybrid material consisting of graphene oxide/multiwalled carbon nanotube/Fe3O4/SiO2
(ELSEVIER SCIENCE BV, 2019)
A new hybrid material was synthesized including magnetic graphene oxide/multiwalled carbon nanotube core shell (GO/MWCNT/Fe3O4/SiO2) and used as magnetic solid phase extraction adsorbent for separation and pre concentration ...
