A novel materials-selection procedure has been developed and implemented in software. The procedure makes use of Materials Selection Charts: a new way of displaying material property data; and performance indices: combinations of material properties which govern performance. Optimisation methods are employed for simultaneous selection of both material and shape. INTRODUCTION The performance of ...

In the Introduction section of this Research Article, description on membrane geometry was incorrect. The first sentence fourth paragraph in section, “Herein we prepared high-silica CHA zeolite membranes ceramic hollow fiber substrates for Kr/Xe separation.” should be revised to read disk This change does not affect interpretation data and conclusions, but guarantees a consistent with other sec...

Wire arc additive manufacturing (WAAM) is a method of metal three-dimensional (3D) printing that has the potential for significant impact on construction industry due to its ability produce large parts with reasonable times and costs. However, there currently lack fundamental data performance structural elements produced using this manufacturing. Seeking bridge gap, compressive behavior resista...

In this paper, a review on microplasma discharges is conducted. The different types and configurations used in microplasmas such as the Cathode Boundary Layer (CBL), Dielectric Barrier Discharge (DBD), Capillary Plasma Electrode Discharge (CPED), Inverted Square Pyramid (ISP), Square Cross Sectional Cavities (SCSC), Radio Frequency Inductively Coupled Discharge (RFIC), Radio Frequency Capacitiv...

Objective To compare the obstetric outcomes of cesarean section in women who had a history of four or more previous cesarean sections with those who had a history of two or three previous cesarean sections. Methods Total 1318 women who underwent repeat cesarean section between January 2013 and January 2016 were retrospectively reviewed. Of these, 244 (18.5%) had previously had four or more ce...

Numerical investigation of cold-formed stainless steel beam–columns at elevated temperatures ranged from 24–960 °C has been performed. The beam–column specimens were subjected to axial compression and minor axis bending. A finite element model was developed validated against available experimental results ambient temperature. An extensive parametric study with 308 lean duplex, austenitic duplex...

The influence of yield strength on the in-plane stability and design structural steel square rectangular hollow section (SHS RHS) beam-columns under compression plus uniform bending is investigated in this study. Ten buckling tests were carried out hot-finished S690 SHS 100×100×4 (in mm) specimens combined uniaxial bending. Finite element (FE) models RHS established, validated employed to perfo...
