An Examination of Cross Sectional Change in Student's Metaphorical Perceptions towards Heat, Temperature and Energy Concepts
(Necmettin Erbakan Univ, 2016)
In science teaching, metaphors are important tools for understanding meaningful learning and conceptual formation by the help of daily life language. This study aims to evaluate how the concepts of heat, temperature and ...
A SAR Study: Evaluation of Bromo Derivatives of 8-Substituted Quinolines as Novel Anticancer Agents
(Bentham Science Publ Ltd, 2017)
Background: Brominated 8-hydroxy, 8-methoxy, 8-amino quinolines 5, 6, 8, 9 and novel cyano 8-hydroxyquinolines 11, 12 were evaluated in vitro for their anticancer effects on various cell lines. 5,7-Dibromo-5, 7-bromo-6, ...
Synthesis, characterization, and SAR of arylated indenoquinoline-based cholinesterase and carbonic anhydrase inhibitors
(Wiley-V C H Verlag Gmbh, 2018)
We report the synthesis of bromoindenoquinolines (15a-f) by Friedlander reactions in low yields (13-50%) and the conversion of the corresponding phenyl-substituted indenoquinoline derivatives 16-21 in high yields (80-96%) ...
Theoretical Study of Synthesis of 1,3-dibromonaphthanlene
(Chem Soc Pakistan, 2018)
Naphthalene derivatives have been attracted the interest for synthesis of natural products having biological properties. Elimination reaction of tetrabromonaphthalene (1) resulted in the formation of 1,3-dibromonaphthalene ...
The inhibition effect of garlic-derived compounds on human immunodeficiency virus type 1 and saquinavir
(Wiley, 2018)
Garlic has been used as a traditional medicine to treat various diseases. Garlic reduces the risk of some diseases. This protective effect is due to the organosulfur compounds of garlic. The aim of this study was to ...
Synthesis, characterization, crystal structures, theoretical calculations and biological evaluations of novel substituted tacrine derivatives as cholinesterase and carbonic anhydrase enzymes inhibitors
(Elsevier Science Bv, 2019)
The six and seven hydrocycle membered disilylanilino acridine (tacrine) analogues (9-11) were synthesized by one-pot procedures. The structures of novel silyl tacrine derivatives were characterized by NMR spectroscopy, ...
Aminopyrazole-substituted metallophthalocyanines: Preparation, aggregation behavior, and investigation of metabolic enzymes inhibition properties
(Wiley-V C H Verlag Gmbh, 2019)
The synthesis, characterization, aggregation behavior, theoretical studies, and investigation of antimicrobial, antidiabetic, and anticholinergic properties of 4-(2-(5-amino-4-(4-bromophenyl)-3-methyl-1H-pyrazol-1-yl)eth ...
Synthesis of novel cyano quinoline derivatives
(Pergamon-Elsevier Science Ltd, 2015)
6,8-Dibromo-1,2,3,4-tetrahydroquinoline (2) and 3,6,8-tribromoquinoline (3) were converted into the corresponding cyano derivatives via copper assisted nucleophilic substitution reactions. While bromination of 6-bromo-8- ...
Effect of heat treatments on the microhardness and tensile strength of Al-0.25 wt.% Zr alloy
(Elsevier Science Sa, 2015)
In the present work, the effect of heat treatments on the microhardness and tensile properties of the Al-0.25 Zr (wt.%) alloy have been investigated. The Al-0.25 Zr (wt.%) alloy was melted in a vacuum furnace, and the ...
Augmented reality in science laboratories: The effects of augmented reality on university students' laboratory skills and attitudes toward science laboratories
(Pergamon-Elsevier Science Ltd, 2016)
This study investigated the effects of the use of augmented reality (AR) technologies in science laboratories on university students' laboratory skills and attitudes towards laboratories. A quasi-experimental pre-test/post-test ...
