On a close to symmetric system of difference equations of second order
(Springer Nature, 2015-12-29)
Closed form formulas of the solutions to the system of difference equations of the second order are found. The domain of undefinable solutions to the system is described.
On a product-type system of difference equations of second order solvable in closed form
(BioMed Central, 2015-10-12)
Sufficient conditions for solving a system of difference equations of second order in closed form are given. Moreover, sufficient conditions for existence of periodic solutions and asymptotic stability of solutions are ...
Boundedness character of a fourth-order system of difference equations
(Springer Nature, 2015-12-01)
Sufficient conditions for boundedness character of solutions of a fourth-order system of difference equations is given.
Nanostructured Polypyrrole-Based Ammonia and Volatile Organic Compound Sensors
The aim of this review is to summarize the recent progress in the fabrication of efcient nanostructured polymer-based sensors with special focus on polypyrrole. The correlation between physico-chemical parameters, mainly ...
Cooperation between an unmanned aerial vehicle and an unmanned ground vehicle in highly accurate localization of gamma radiation hotspots
(SAGE Publications, 2018-01-01)
This article discusses the highly autonomous robotic search and localization of radiation sources in outdoor environments. The cooperation between a human operator, an unmanned aerial vehicle, and an unmanned ground vehicle ...
Efficient control of automotive R744 heat pump using Nelder-Mead simplex method
This paper deals with coefficient of performance maximization for automotive R744 heat pump using Nelder-Mead simplex method.
Induction of Laccase, Lignin Peroxidase and Manganese Peroxidase Activities in White-Rot Fungi Using Copper Complexes
Ligninolytic enzymes, such as laccase, lignin peroxidase and manganese peroxidase, are biotechnologically-important enzymes. The ability of five white-rot fungal strains Daedaleopsis confragosa, Fomes fomentarius, Trametes ...
Effect of Magnetic Nanoparticles on Tobacco BY-2 Cell Suspension Culture
Nanomaterials are structures whose exceptionality is based on their large surface, which is closely connected with reactivity and modification possibilities. Due to these properties nanomaterials are used in textile industry ...
Ion exchange chromatography and mass spectrometric methods for analysis of cadmium-phytochelatin (II) complexes
In this study, in vitro formed Cd-phytochelatin (PC2) complexes were characterized using ion exchange chromatography (IEC) and matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry. The ...
The Role of Metallothionein in Oxidative Stress
Free radicals are chemical particles containing one or more unpaired electrons, which may be part of the molecule. They cause the molecule to become highly reactive. The free radicals are also known to play a dual role in ...
