Internal oxidation of Fe–Cr alloys were investigated in dry and humid atmospheres at temperatures of 973 and 1 073 K in order to clarify the effect of humidity on the oxygen permeability in internal oxidation zone. The oxygen partial pressure in the chamber was fixed by Fe/FeO powder mixture. The calculated oxygen permeability increases linearly

A high energy density, Zn/MCM-41/O2 microbattery of 1.5 V, measured 1 cm2 area and 100 μm thick, was able to produce current as high as 27 mA. The electrochemical system is popularly dubbed as breathing battery since it utilizes oxygen from ambient air, which is free, unlimited, and does not requires storage. A novel nanoporous inorganic MCM-41 ma

Guardian device is prayer aid that designed for visually impaired or blind ppl, to perform prayer or other duties. It is because, nowadays there are many ppl that suffer from minor to variour serious vision disability which make diffeculties for those who are independance living. Most common vision problem is praying. Therefore, this device is desi

For application in animal feed, a phytase of interest must have high activity in the broad range prevalent industrial condition and in digestive tract of the animal. The present investigation describes approaches to rationally engineer a phytase with better activity profiles. Computer modelling is used to identify and examine active site of phyFAUI

The COVID-19 pandemic in 2020 has caused a major transformation in the education system around the world. Due to the closure of schools and other learning institutions, the teaching and learning that were once face to face are now conducted online. Sudden change of education landscape has put educators and students in harrowing time. This paper rev

The multidisciplinary field of tissue-engineering was born as a means to restore or replace diseased tissue with new living tissue that is designed or constructed to meet the needs of each individual patient. Scientific advances in biomaterials, stem cells,growth factors, and biomimetic environments have created opportunities to reconstruct tissues

Recently, many researches all over the world are focusing on ways of utilizing either industrial or agricultural wastes as a source of raw materials for the construction industry. The aim of this study is to determine the optimum proportion of durian saw dust as partial replacement for fine aggregate. These wastes utilization would not only be econ

This study examines evolution characteristics of inelastic strains and materials damage in Sn-4Ag-0.5Cu (SAC405) solder joints of a BGA package under cyclic mechanical stressing. For this purpose, a finite element model of the assembly under four-point bend test set-up is employed. Strain rate-dependent response of the solder is represented by Anan

Progressive materials damage process in solder joint under cyclic shear deformation is examined in this study. A 3-D finite element model of a single reflowed SAC405 solder specimen is developed for this purpose. Cyclic relative displacement cycles between zero and 1.0 mm at displacement ramp rate of 2.0 mm/sec. is applied in the direction parallel

leading to pneumonitis with a poor prognosis. Tocilizumab, a type of humanized monoclonal antibody antagonizing interleukin-6 receptors, is currently utilized to treat COVID-19. The present study reviews tocilizumab adverse drug events (ADEs) reported in the World Health Organization (WHO) pharmacovigilance database. Research design and methods: Al
