Australia’s residents are still exposed to asbestos in many buildings that contain asbestos cement and other asbestos products‚ especially when they are demolished . Products which contain asbestos can generate fibres when they are damaged‚ weathered‚ old or demolished which can cause air borne fibres to be released into the atmosphere where they can be harmful to humans. Asbestos is a set of six naturally occurring silicate minerals that have been exploited commercially for their desirable physical

Aherne-Williams Fibre-Optic Telecommunications Systems: Fibre-optic telecommunications is simply a method of transmitting information from one place to another extremely fast. This is done by shooting pulses of light through an optical fibre. Creating the optical signal involving the use of a transmitter‚ relaying the signal along the fiber‚ ensuring that the signal does not become too distorted or weak‚ receiving the optical signal‚ and converting it into an electrical signal. An optic-fibre is a small

a bid to reduce the aircraft weight‚ increases fuel efficiency and extend the service range of the aircraft. The A400M is too many a pioneering aircraft in the increase use of composite technology and my focus will be on the wings and how Carbon Fibre Reinforced Polymers (CFRP) are utilised through the design and manufacturing of this assembly. The wings are one of the most complex parts of the aircraft‚ having been constrained to produce a wing that weighs “6500 kg/14‚330 lb‚ but can contain

Is Witchcraft Rational? Human nature has always instigated us to try and look for explanations for what happens around us. Psychology looks for the explanations for human behavior‚ meteorology looks for explanations for weather and the police now look for scientific explanations to solve a crime. The means we have today to investigate cause and effect are different from how they were even a decade ago let alone in the ancient civilizations when witchcraft and magic supposedly originated‚ not to

Introduction to Different Dyeing Machineries Dyes‚ Theory of Dyeing‚ Classification of Dyes and its application Dyeing & Printing 1.0. Introduction to Textile Dyeing 3 Dyeing is the process of imparting colours to a textile material in loose fibre‚ yarn‚ cloth or garment form by treatment with a dye. Dyeing is also the process of coloring textile materials by immersing them in an aqueous solution of dye‚ called dye liquor. Normally the dye liquor consists of dye‚ water and an auxiliary.

The tester should be placed on the tooth surface adjacent to a pulp horn (highest density of nerve fibres). According to Lin and co-workers (2007)‚ the optimum site of tester placement on molars is the mesiobuccal cusp tip. An ionic shift in dentinal tubule fluid causes local depolarisation and action potential generation from intact Aδ nerves‚ giving
