Federal Government
An introduction and overview of the structure of the U.S. government. A high school senior discovers the makeup of our federal government and how the three branches of government work. This is a very old video and so students might be turned-off by some of the outfits. It is a 15 minute video. Students would benefit from a map of Washington DC. Not much depth in this video.

Restoring a tooth (CAD-CAM Ceramic) - Part 3
This video shows the ceramic 'build-up' stage of the production of a ceramic crown to restore a damaged tooth. In this video, ceramic powders are applied by brush to the substructure (see Videos 7 and 8). The ceramic powders are fired to sinter them into a hard structure, and then refired and adjusted until the desired shape is achieved. From set of videos used in Advanced Restorative Course in School of Clinical Dentistry, The University of Sheffield.

Article :: Create Text-Based Links in Dreamweaver 8
In this lesson, you’ll develop the initial framework of the site structure by developing placeholders for the pages in the Yoga Sangha project site. You’ll link these pages together using Dreamweaver’s visual site-mapping tools to create a working test site. Creating this kind of framework through pages and links in a bare but functional version of the site can help you test the navigation that you have developed. Testing the proposed site structure before creating the design will help you

Enhancing Physics Knowledge for Teaching – Mechanics
The approach we’ll be taking in this session will set the structure for the whole of the module. We’ll begin by introducing a problem that will cover the main learning objectives of the session. We’ll then look at what is required to solve this problem; We’ll build up this knowledge step by step, applying it to the solution of the problem as we proceed. When we get to the end we will have found a solution to the problem. Then we’ll invite you to try some problems covering again some o

Environmental Geology
There is now a greater interest in the environment than ever before and we face concerns about the environmental impacts of almost every aspect of our daily lives. Water, soil, air and the biological environment can all be changed dramatically by the activities of industrial societies like our own, not least through mechanisms which are controlled by essentially geological processes. Waste disposal, contamination of land by industry, the impacts of mining, water pollution and even air quality (t

Roll-bonded aluminium alloy diffusion couple in the as-rolled condition.
This micrograph shows the grain structure of a roll-bonded aluminium alloy diffusion couple in the as-rolled condition. The upper half of the couple is Al-0.5Fe-1.0Mn (wt.%), the lower half is Al-1.0Si (wt.%). Rolling heavily deforms the microstructure, producing thin, elongated grains parallel to the roll-bonded interface.The Barker's etch produces a thick oxide layer on the grains of aluminium (anodising). When viewed in cross-polarised light, interference in the oxide layer produces colours w

Carbon-carbon composite
Carbon-carbon composites are manufactured from continuous carbon fibres which are woven in a two or three dimensional pattern. The fibres are then impregnated with a polymeric resin. After the component has been shaped and cured the matrix is pyrolysed by heating in an inert atmosphere. This converts the matrix to carbon chain molecules which are densified by further heat treatments. The resulting composite consists of the original carbon fibres in a carbon matrix. Carbon-carbon composites have

Coarse open celled aluminium foam produced by infiltration of sintered salt (FOAM-U-LIKE)
FOAM-U-LIKE (Foaming of aluminium metal using lightly interconnected kevelled elements) is a very inexpensive route for the production of coarse open celled foams. It allows a reasonable degree of control over cell size and shape, and results in relatively uniform morphology. The interconnectivity of pores can be controlled by varying the degree of sintering of the precursor. In this case, grains of 1-4mm diameter have been sintered at 600 degrees C for just 10 minutes, giving rise to lightly in

Spherulite in poly-3-hydroxy butyrate (PHB)
Polymer melts often crystallise from heterogeneous nuclei to form ribbon-like lamellae, which have a folded chain molecular structure. They commonly radiate outwards from the nucleation point, to form spherical features called spherulites - which are often quite large. The characteristic Maltese cross pattern, seen when viewed between crossed polars, results from isoclinic fringes formed when one of the principal vibration directions is approximately parallel to the polariser. In some cases (inc

Roll-bonded aluminium alloy diffusion couple annealed for 30 minutes at 600°C.
This micrograph shows the grain structure of a roll-bonded aluminium alloy diffusion couple annealed for 30 minutes at 600°C. The upper half of the couple is Al-0.5Fe-1.0Mn (wt.%), the lower half is Al-1.0Si (wt.%). Annealing has recrystallised the microstructure. The Al-Fe-Mn alloy has many intermetallic particles (the dark phase). These help create recrystallisation nuclei, hence this alloy has a high density of small grains relative to the Al-Si alloy.The Barker's etch produces a thick oxide
