Aluminium mesh is used as the infill to make security door, grille, fence and partition as illustrated in the the photos of this posting.

It can also be used for making machinery guards, security enclosures, decorative cum security screens, open air shelves and etc.

There are numerous benefits in choosing the aluminium mesh for the above mentioned usage/ purpose, namely, anti-rust, fire proof, vermin proof, good visibility, easy passage of air and light while ensuring security and protection.

What are Refractory Materials?

There was a time when I would simply pull out my trusty Webster’s Tome. I would efficiently thumb to the desired entry, proudly making full use of the alphabetical skills acquired through years of primary education. Voila! Having quickly located the desired term, I would faithfully and obediently parrot the appropriate definitions. But times have changed, and I have kept up with them. I now depend, as I’m sure is true for most of us, on Google and Wikipedia for my primary didactic guidance.

So I Googled “Refractory”.

Webster could never have anticipated the boundless diversity of definition declared relative by Google’s algorithms! You may enjoy looking for yourself, but let me assure you that for our purposes, refractory is not “the recovery phase after orgasm during which it is physiologically impossible for an individual to have additional orgasms” http://en.wikipedia.org/wiki/Refractory_period(sex)

And did you know that in the religion of the Vedic period in India, there are certain words that, when used as a Mantra, affect a spiritual transformation in the individual repeating them? Om (or Aum) is perhaps the most well known. The meaning of the words (and the self) becomes lost in the rhythm of repetition. The void that this loss creates invites change and hopefully an accompanying enlightenment. 

How in the world did I get from “Refractory” to refractory Karmas? The Six Degrees of Separation of People states that each person on Earth is only 6 acquaintances from every other person. I’d like to be the first to declare a similar relationship for information, my just conceived and soon to be famous Six Clicks of Separation of Information theory, each topic searched for is only 6 clicks away from all other topics

I’m tempted yet again to abandon this new hyperlink knowledge fest and dust off my trusted old tome. But I never do. I love this new world of fast and easy information. I love having the world’s largest library sitting on my desk. Maybe I won’t become famous for my theory, but I’ll bet one day I’ll learn to use technology as efficiently as that old dictionary.

In the mean time, you’ll have to read more of the blog to know what our discussion is all about. Since I already know, I’m just going to go practice my mantra. “Aum refractory, Aum refractory, Aum refractory…”

High Temperature Resonant Ultrasound Spectroscopy: A Review

Abstract The measurement of elastic constants plays an important role in condensed matter physics and materials characterization. This paper presents the resonant ultrasound spectroscopy (RUS) method for the determination of elastic constants in a single crystal or amorphous solid. In RUS, the measured resonance spectrum of a properly prepared sample and other information such as geometry, density, and initial estimated elastic constants are used to determine the elastic constants of the material. We briefly present the theoretical background and applications to specific materials; however, the focus of this review is on the technical applications of RUS, especially those for high-temperature measurements. 1. Introduction: Elastic Constants and Measurement Methods The elastic response of a solid is determined by the full set of independent elastic constants, which are a measure of the material’s interatomic forces and, specifically, the curvature of the potentials around the equilibrium spacing. Elastic constants are a sensitive probe into the atomic environment of a crystal lattice, and changes in elastic constants are a useful tool for investigating critical phenomenon. Elastic constants are involved in many fundamental phenomena in solid-state physics: they are important parameters in equations of state, lattice dynamics, and phonon spectra; they are also linked to other quantities in thermodynamics such as coefficient of thermal expansion, Debye temperature, Grüneisen parameter, and so on. The measurement of elastic constants is of interest not only to engineers and materials scientists, but also to researchers in many areas of fundamental and applied physics. Numerous theoretical and experimental methods are available for evaluating elastic constants. If the equation for the interatomic potential is known, the elastic constant can be calculated from first principles. The results from ab initio calculations for some crystalline solids with known atomic structures and potentials are usually in reasonable agreement with the experimental data. For simple, accurate and efficient determination of elastic properties of materials, various ultrasonic and nonultrasonic experimental techniques are often preferred. Many experimental techniques [1–3] have been developed and employed for measuring the elastic constants of different types of materials. The selection of technique depends on factors such as the composition, structural characteristic and size of the sample, desired accuracy of measurement, and, of course, the availability of equipment and expertise. Various common techniques can be roughly categorized according to the major parameters that are evaluated or the primary equipment that are used (Table 1). The accuracy of a given experimental method depends on many factors other than the fundamental nature of the method itself. However, frequencies are one of the easiest quantities to measure, and resonance methods typically depend on many more frequency measurements than variables being determined. For these reasons, RUS has emerged as one of the most accurate methods for elastic constant measurements.
