The present research investigates joints welding of 304L austenitic stainless steel using metal inert gas (MIG) method. explores the effect process parameters (arc voltage, wire feed rate, and electrode diameter) on mechanical properties steel. above variables are varied respectively with 18.5, 19, 19.5 V, 116, 127, 137 mm/s, 0.8, 1, 1.2 mm, E308L as a filler electrode. design matrix experiment...

Pt/Ir electrodes have been extensively used in neurophysiology research in recent years as they provide a more inert recording surface as compared to tungsten or stainless steel. While floating microelectrode arrays (FMA) consisting of Pt/Ir electrodes are an option for neuroprosthetic applications, long-term in vivo functional performance characterization of these FMAs is lacking. In this stud...

Two designs for an integrated photoelectrolysis system that uses a 10× concentrating solar collector have been investigated in detail. The system performance was evaluated using a multi-physics model that accounted for the properties of the tandem photoabsorbers, mass transport, and the electrocatalytic performance of the oxygen-evolution and hydrogen-evolution reactions (OER and HER, respectiv...

Low frequency noise performance is the key indicator in determining the signal to noise ratio of a capacitively coupled sensor when used to acquire electroencephalogram signals. For this reason, a prototype Electric Potential Sensor device based on an auto-zero operational amplifier has been developed and evaluated. The absence of 1/f noise in these devices makes them ideal for use with signal ...

The application of voltammetric methods using different rates of polarisation on HMDE reveal inert or labile behaviour of Cd- or Zn- complexes in the presence of excessive cadmium or zinc ions in solution. This phenomenon was demonstrated first on the simplest phytochelatin - complex of peptide (gamma-Glu-Cys)(2) Gly with cadmium, later on rabbit liver metallothioneins - Cd(7) MT in the presenc...

BACKGROUND Although pilot trials of transcranial direct current stimulation (tDCS) in aphasia are encouraging, protocol optimization is needed. Notably, it has not yet been clarified which of the varied electrode montages investigated is the most effective in enhancing language recovery. OBJECTIVE To consider and contrast the predicted brain current flow patterns (electric field distribution)...

Welding is a manufacturing process, which is carried out for joining of metals by Metal Inert Gas (MIG) welding. This is the one types of Gas Metal Arc Welding (GMAW), in which Argon and Helium is used as a inert gas. Shielding gas Argon and Helium is used and consumable electrode is used which also plays role of conductor. MIG welding is versatile, gives very little loss of alloying elements a...

a subgroup h of a group g is called inert if‎, ‎for each $gin g$‎, ‎the index of $hcap h^g$ in $h$ is finite‎. ‎we give a classification ‎of soluble-by-finite groups $g$ in which subnormal subgroups are inert in the cases where $g$ has no nontrivial torsion normal subgroups or $g$‎ ‎is finitely generated‎.
