Mechanical performances of hip implant design and fabrication with PEEK composite
(2021-06-01)
Artificial bone implant materials need porosity for nutrient distribution, moderate pore size to provide cell cultures and bone-like mechanical properties. The homogenisation of discrepancies between the microstructure of ...
Bursting oscillations and bifurcation mechanism in a fully integrated piecewise-smooth chaotic system
(2021-05-29)
This paper aims to show and investigate bursting oscillator and bifurcation phenomena in a piecewise-smooth memristor-based Shimizu-Morioka (SM) system. To make the circuit low power consumption and portable in practice, ...
THE EFFECT OF MINING WASTE ON THE DURABILITY INDICATORS OF CEMENT-BASED COMPOSITES
(2021-05-25)
The need for infrastructure development is of major importance and the projected global infrastructure investment between 2013-2030 is estimated in the excess of £30 trillion to support the rapid growth of societies and ...
Indirect Vibration of the Upper Limbs Alters Transmission Along Spinal but Not Corticospinal Pathways
(2021-05-17)
The use of upper limb vibration (ULV) during exercise and rehabilitation continues to gain popularity as a modality to improve function and performance. Currently, a lack of knowledge of the pathways being altered during ...
A Comprehensive Phylogenomic Platform for Exploring the Angiosperm Tree of Life
(2021-05-13)
The tree of life is the fundamental biological roadmap for navigating the evolution and properties of life on Earth, and yet remains largely unknown. Even angiosperms (flowering plants) are fraught with data gaps, despite ...
Simultaneous Deep Measurements of CO Isotopologues and Dust Emission in Giant Molecular Clouds in the Andromeda Galaxy
(2021-05-05)
We present simultaneous measurements of emission from dust continuum at 230 GHz and the J=2-1 $^{12}$CO, $^{13}$CO and C$^{18}$O isotopologues at $\sim$ 15 pc resolution from individual Giant Molecular Clouds (GMCs) in the ...
QR codes in Engineering Laboratories –Improving Student Safety Engagement
(2021-05-01)
Engineering is a practical discipline and laboratory work is a fundamental necessity of engineering curricula and majority of engineering modules run by universities have significant elements of practical work embedded in ...
Influence of slicing parameters on surface quality and mechanical properties of 3D-printed CF/PLA composites fabricated by FDM technique
(2021-04-28)
This present study focuses on evaluation of mechanical properties of three dimensional (3D)-printed carbon fiber/polylactic acid (CF/PLA) composites, using fused deposition modeling (FDM) technique. The composites were ...
Prediction of steady-state two-phase flow of nitrogen + extinguishant in the pipeline and a correlation for mass flow rate
(2021-04-27)
Nitrogen used for pressurization of a fire extinguisher could be partially dissolved in the fire extinguishing agent, forming a binary mixture accompanied by a phase change while flowing inside the pipeline. Notwithstanding ...
Discovery of an Extremely Short Duration Flare from Proxima Centauri Using Millimeter through FUV Observations
(2021-04-21)
We present the discovery of an extreme flaring event from Proxima Cen by the Australian Square Kilometre Array Pathfinder (ASKAP), Atacama Large Millimeter/submillimeter Array (ALMA), Hubble Space Telescope (HST), Transiting ...
