Identifying weak foci and centers in the Maxwell-Bloch system
(Academic Press Inc Elsevier Science, 2015)
In this paper we identify weak foci and centers in the Maxwell Bloch system, a three dimensional quadratic system whose three equilibria are all possible to be of center-focus type. Applying irreducible decomposition and ...
Dynamical analysis of a two prey-one predator system with quadratic self interaction
(Elsevier Science Inc, 2018)
In this paper we investigate the dynamical properties of a two prey-one predator system with quadratic self interaction represented by a three-dimensional system of differential equations by using tools of computer algebra. ...
Electrical, optical, and mechanical percolations of multi-walled carbon nanotube and carbon mesoporous-doped polystyrene composites
(Sage Publications Ltd, 2020)
In this study, we have investigated and compared electrical, optical, and mechanical properties of polystyrene thin films with added multi-walled carbon nanotube and carbon mesoporous. Surface conductivity (sigma), scattered ...
An exploration of solutions to two related Hofstadter-Huber recurrence relations
(Pergamon-Elsevier Science Ltd, 2020)
In this study, we explore the properties of certain solutions of two Hofstadter-Huber recurrence relations. The first is Hofstadter's V-recurrence, which is defined by the nested recurrence relation V(n) = V(n - V (n - 1)) ...
Antimicrobial and physical properties of chitosan films incorporated with turmeric extract
(Elsevier Science Bv, 2017)
In this study, the effects of turmeric extract incorporation on the antibacterialand physical properties of the chitosan films were evaluated. Turmeric containing chitosan-based film was produced with casting procedure and ...
On Hofstadter Heart Sequences
(Wiley-Hindawi, 2017)
The Hofstadter Q-sequence and the Hofstadter-Conway $10000 sequence are perhaps the two best known examples of meta-Fibonacci sequences. In this paper, we explore an unexpected connection between them. When the Q-sequence ...
Adsorptive removal kinetics of anionic dye onto chitosan films doped with graphene oxide: An in situ fluorescence monitoring
(Taylor & Francis Inc, 2018)
The aqueous adsorption of a fluorescent dye (pyranine) onto crosslinked chitosan-graphene oxide composite films was studied. In situ fluorescence monitoring technique is introduced as easy and fast experimental technique ...
Corrosion behaviour of twin belt cast EN AW 7075 alloy
(Wiley-V C H Verlag Gmbh, 2013)
The corrosion behaviour of the twin belt cast EN AW 7075 alloy is governed by intermetallic phases, namely Al-12(Fe,Cr,Mn)(3)Si, Mg2Si and CuAl2, and by Mg(Zn,Cu,Al)(2) precipitates. The former are responsible for pitting ...
Cation Effect on Slow Release from Alginate Beads: A Fluorescence Study
(Springer/Plenum Publishers, 2014)
In this study, spherical alginate beads containing pyranine (P-y) as a fluorescence probe were prepared by ionotropic gelation of a sodium alginate solution. The steady state fluorescence technique was used to study pyranine ...
Investigation of Drying of Poly(N-isoproplacrylamide-co-acrylamide) by Fluorescence Technique
(Wiley-Blackwell, 2013)
The steady-state fluorescence technique was performed on drying of various molar percentages of poly(N-isopropylacrylamide-co- acrylamide) [poly(NIPA-co-AAc)] to elucidate the mechanism of temperature-induced phase separation ...
