The modification of aluminium content of natural zeolites with different composition
(ELSEVIER SCIENCE BV, 2019)
A series of natural zeolites with different compositions were modified by formation of hydrated aluminium oxide onto the zeolite structure after NaOH treatment of the natural zeolites. Natural and modified zeolites were ...
Alternative plants to be used in natural dyeing on wool yarn fibers
(TAYLOR & FRANCIS INC, 2019)
In this study, 28 plants were collected from nature and the extracts were obtained with and without mordants from these plants. The wool yarns (3.5 N m natural wool carpet yarns obtained from the natural fibers 60 s, 23.3 ...

Objectives: To present an unusual major mechanical complication of central venous catheterization (CVC). Methods: Between January 2016 and January 2017, data of the patients who underwent CVC in Cumhuriyet University in ...
The physiological and lifespan alterations in Caenorhabditis elegans exposed to different dosages of melatonin
(UNIV KARACHI, 2019)
Aging is a process that begins at birth and ends with death. This process is accompanied by environmental effects, which cause structural and functional changes in cells and tissues. With regards to healthy aging, melatonin ...
Synthesis of tetra-substituted metallophthalocyanines: Spectral, structural, computational studies and investigation of their photophysical and photochemical properties
(PERGAMON-ELSEVIER SCIENCE LTD, 2019)
This work presents the synthesis of peripherally and non-peripherally tetra-substituted metallophthalocyanines (6-14) containing the 2-(3,4-dimethoxyphenyl)ethanol group. The synthesized compounds were characterized by ...
A study of stability and bifurcation analysis in discrete-time predator-prey system involving the Allee effect
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2019)
This paper deals with a discrete-time predator-prey system which is subject to an Allee effect on prey. We investigate the existence and uniqueness and find parametric conditions for local asymptotic stability of fixed ...
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, ...
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 ...
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 ...
