5.3 Purposeful and purposive behaviour

It is possible, as observers, to ascribe a purpose to what we or others do, the actions we take. How particular actions, or activities are construed will differ from observer to observer because of their different perspectives, which arise from their traditions of understanding.

4.3.5 Domestic campaigns

An important aspect of efforts to reduce nutrient inputs to water bodies is the modification of domestic behaviour. Public campaigns in Australia have encouraged people to:

  • wash vehicles on porous surfaces away from drains or gutters

  • reduce use of fertilizers on lawns and gardens

  • compost garden and food waste

  • use zero- or low-phosphorus detergents

  • wash only full loads in washing machines

9.913-A Intensive Neuroanatomy (MIT)
The course will start with an overview of the central and peripheral nervous systems (CNS and PNS), the development of their structure and major divisions. The major functional components of the CNS will then be reviewed individually. Topography, functional distribution of nerve cell bodies, ascending and descending tracts in the spinal cord. Brainstem organization and functional components, including cranial nerve nuclei, ascending / descending pathways, amine-containing cells, structure and in

22.55J Principles of Radiation Interactions (MIT)
The central theme of this course is the interaction of radiation with biological material. The course is intended to provide a broad understanding of how different types of radiation deposit energy, including the creation and behavior of secondary radiations; of how radiation affects cells and why the different types of radiation have very different biological effects. Topics will include: the effects of radiation on biological systems including DNA damage; in vitro cell survival models; and in

Low magnification SEM image of open cell polyurethane foam
If a gas is injected into a liquid it forms a cellular foam structure. When a thermoset prepolymer of low viscosity is foamed, the polymer can drain from the cell walls (driven by surface tension) before it sets at the cell edges, leaving an open-celled foam. The cell edges have three concave sides, giving rise to the tri-cuspid cross section visible at the bottom of this image. The average co-ordination number for the nodes (where struts meet) is four, giving tetrahedral junctions.

Alporas' closed cell aluminium foam
Additions are made to molten aluminium or aluminium alloy to modify the melt viscosity and make it suitable for foaming. 1 to 3 wt% titanium hydride is then added to the melt, and this foams the melt by releasing hydrogen. The foamed melt solidifies to yield a closed cellular structure with an average cell size of 4.5 mm

Bianca Goes Where the Wind Blows
In this segment from Cyberchase, Bianca gives her niece Mikaela a kite for her birthday. Bianca is determined to find the best place to fly it. To help with their search, Bianca creates a wind gauge that measures how hard the wind blows. After taking wind gauge readings in different spots around the park, they are able to find a spot where the kite soars beautifully. (03:31)

Simple Subtraction From 4 Song "Elmo Has 4 Ducks" - Sesame Street
In this video snippet from "Sesame Street", Elmo sings about his 4 ducks. During each verse of the song, one duck at a time leaves, allowing the viewer to tell how many ducks are left. This would be a great song for introducing subtraction to very young children. (2:04)

"Eden Rock" by Charley Causley (poetry reading)
A projection of the afterlife, drawn from idyllic memories of childhood. He pictures his parents as they used to be when he was a child. Most parents take photographs and videos of their children to provide lasting memories to treasure in later years. But very few take pictures of themselves - and it is pictures of the parents that the children will want to see: that is what THEY saw at the time. Women grow conscious of the toll taken by passing years and become more and more reluctant

1.2 The origins of coal

If you examine a piece of coal, at first sight it appears black and rather homogenous. However, closer inspection generally shows a series of parallel bands up to a few millimetres thick. Most obvious are shiny bands that break into angular pieces if struck. Between them are layers of dull, relatively hard coal and thin weak layers of charcoal-like carbon. Coal splits easily along these weak layers, which crumble to give coal its characteristic dusty black coating.

2.3.4 Geophysical methods — borehole logging

If a core is not recovered from a borehole, another way to assess the types of rock that it penetrates is to measure their physical properties. Mounting a string of electronic instruments behind the drill bit most conveniently does this: it allows the properties of the rock to be monitored as the borehole is drilled. An alternative is to lower instruments down the completed borehole by cable; hence the name wireline logging.

Such logging measures several physical properties of th
