The Use of Numerical Modelling to Determine the Conditions of Regeneration of Medium Carbon Steel

Archives of Metallurgy and Materials, 2017
In the paper, the regeneration process of the material in grade C45 using the MAG welding was analysed. The effect of preheating on the properties of the regenerated layers was determined.

Modification of Canola Oil Physicochemical Properties by Hexane and Ethanol with Regards of Its Application in Diesel Engine

Energies, 2021
A mixture of canola oil (Co), n-hexane (Hex), and ethyl alcohol (Et) was proposed as a new energy material for powering diesel engines. For this purpose, surface tension, density, and viscosity measurements, as well as engine tests, were performed for 88%

A Practical Alternative Model To Approximate A Fully Two Dimensional Thermally Non-Symmetric Annular Fin Efficiency

International Journal of Applied Mechanics and Engineering
A new practical and approximate two-dimensional is developed to take into account the thermally non-symmetric annular tick fin model and to avoid the laborious solution involving additional calculation of infinite eigenvalues.

An exponential-trigonometric higher order shear deformation theory (HSDT) for bending, free vibration, and buckling analysis of functionally graded materials (FGMs) plates

Advanced Composites Letters, 2020
Two assumptions have been made based on by this proposed theory, which come from recently developed exponential–trigonometric shape function for transverse shear deformation effect and a simple higher order shear deformation theory for plate, based on a ...

Feasibility and Safety of Somato‐Cognitive Coordination Therapy for Cerebellar Ataxia Following Pediatric Brain Tumor Treatment

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Cerebellar ataxia after pediatric brain tumor treatment can cause persistent gait, balance, and speech impairment, yet no established rehabilitation strategy exists. Somato‐cognitive coordination therapy (SCCT) is a virtual reality–guided intervention designed to promote sensorimotor integration through visually constrained reaching
