The effect of ball milling on properties of sintered manganese-doped alumina
(Elsevier, 2019)
Alumina-based compounds have many technological applications and attract great attention even after decades of investigation, due to their good chemical, electrical, and mechanical properties. A mixture of several alumina ...
Workspace design for crane cabins applying a combined traditional approach and the Taguchi method for design of experiments
(Taylor & Francis Ltd, Abingdon, 2016)
Procedures in the development process of crane cabins are arbitrary and subjective. Since approximately 42% of incidents in the construction industry are linked to them, there is a need to collect fresh anthropometric data ...
Investigation of ZnFe2O4 spinel ferrite nanocrystalline screen-printed thick films for application in humidity sensing
(Wiley, 2019)
Zinc ferrite nanocrystalline powder was obtained by solid state synthesis of starting zinc oxide and hematite nanopowders. Field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM), ...
Nonlocal mass-nanosensor model based on the damped vibration of single-layer graphene sheet influenced by in-plane magnetic field
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
Nano-materials such as graphene sheets have a great opportunity to be applied in development of a new generation of nanomechanical sensors and devices due to their unique physical properties. Based on the nonlocal continuum ...
Influence of mechanical activation on functional properties of barium hexaferrite ceramics
(Elsevier Sci Ltd, Oxford, 2018)
Barium hexaferrite ceramics were prepared using mechanically activated mixtures of iron and barium titanate. The 60:40 mass% Fe:BaTiO3 powder mixtures were mechanically activated for different times (100-240 min) and ...
Multistep generalized transformation method applied to solving equations of discrete and continuous time-fractional enzyme kinetics
(Elsevier Science Bv, Amsterdam, 2017)
In this paper, Caputo based Michaelis-Menten kinetic model based on Time Scale Calculus (TSC) is proposed. The main reason for its consideration is a study of tumor cells population growth dynamics. In the particular case ...
Structural investigation of mechanically activated ZnO powder
(Elsevier Science Sa, Lausanne, 2015)
Commercially available ZnO powder was mechanically activated in a planetary ball mill. In order to investigate the specific surface area, pore volume and microstructure of non-activated and mechanically activated ZnO powders ...
Optimization of gravity flow discharge chutes under the speed dependent resisting forces: Maximizing exit velocity
(Elsevier, Amsterdam, 2015)
Using the optimal control theory, the problem of finding profiles of gravity flow discharge chutes required to achieve maximum exit velocity of granular material under the speed dependent resisting forces is solved. A model ...
DUV fluorescence bioimaging study of the interaction of partially reduced graphene oxide and liver cancer cells
(IOP Publishing Ltd, 2018)
The interaction of partially reduced graphene oxide (prGO) and Huh7.5.1 liver cancer cells was investigated by means of DUV fluorescence bioimaging. The prGO sample was obtained by the reduction (to a certain extent) of ...
Achieving sustainable work of the heat pump with the support of an underground water tank and solar collectors
(Elsevier Science Sa, Lausanne, 2015)
This paper deals with the methodology of sizing a sustainable heating-cooling system, which consists of a heat pump, thermo-solar collectors and underground water tank, as a seasonal thermal energy storage. The methodology ...
