Improving Your Commute
Road traffic is a challenging societal problem, and with the increasing crowding of areas in and around cities, it is only becoming worse. With the proliferation of wireless connectivity, smartphones (think cheap embedded computers), it is now possible to continuously monitor urban areas using mobile sensors carried by people
A Field View of Soil - Digging Around
The purpose of this resource is to understand that variations in landscape can affect soil properties. Students investigate variations in the soils around their school to discover that soil properties like moisture and temperature exhibit considerable variability across a single landscape. They also identify factors such as slope, shade, plants, compaction, which affect the appearance of soils and their ability to hold moisture.
Using GLOBE Data to Analyze Land Cover
The purpose of the resource is to develop hypotheses about which environmental factors are most important to plants.
Seaweed Reproductive Phenology Protocol
The purpose of this resource is to classify and count the reproductive phenological phases of receptacles on selected seaweed species. Students will classify and count the reproductive phases of seaweed plants within a 1-meter x 1-meter plot in the inter-tidal zone.
Energy Technology
This course looks at all forms that energy exists. It explains how energy is used in: transport, agriculture, industry, commerce and households. It describes how energy is stored using storage systems such as: battery, flywheels, compressed air, chemical energy systems and pumped storage. This course explains the problem of depletion of energy resources. It describes the environmental damage associated with the use of fossil fuels, acid rains, dangers posed by leaded fuels, oil spills, gas leaks

NASA KSNN What do animals need to live?
There are many different habitats on the Earth. These vary in the landforms, sources of water, and climate conditions. Plants and animals are specially adapted to live in their habitats. Animals suited to live in the desert (very dry, either hot or cold) would have a difficult time living in the tropical rain forest (warm and very wet). Grades K-2
Virtual yeast cell
This rich learning object is used to introduce yeast cytology to students taking Module D24BS3 Brewery Yeast Management as part of the MSc in Brewing Science. The virtual cell permits the students to understand structure and function of yeast organelles.

Human Cloning and Human Rights: Promises and Perils
Ignore the noisy debate around cloning, Rudolf Jaenisch
quietly insists, and instead look closely at the biology involved. First, note that there are two different kinds of cloning: reproductive cloning, the attempt to create an exact replica of a human being, which Jaenisch believes to be both biologically flawed and morall
Howard Davies in Conversation with Lord Goldsmith QC
The separation of powers idea is at the heart of all legal democracies. Yet within those democracies there will often be positions of high office which require their holders to perform functions which are both legal and political. In this series of events senior figures who hold or have held positions of this type talk about their lives in the law, the nature of their office, the institutions which they serve, their roles and responsibilities within those institutions, the role of lawyers in gov
Introduction to Project Management
This module is the introduction to the University Extension online course, Introduction to Project Management. Project management has been proven to be the most effective method of delivering products within cost, schedule, and resource constraints. This intensive and hands-on course gives you the skills to ensure your projects are completed on time and on budget while giving the user the product they expect. You will gain a strong working knowledge of the basics of project management and be abl
High 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, and some remnants of collapsed cell walls can be seen at the cell edges.

Although the processing route is complicated and the product expensive, there is a high degree of control over the cell structure of such foams and the final shape can be controlled to meet near-net-shape requirements.
Additions such as SiC are made to molten aluminium or aluminium alloy to modify the melt viscosity and make it suitable for foaming. Calcium carbonate is then added to the melt which is solidified to form a precursor which can be foamed in a controlled manner by a subsequent heat treatment. The resulting foam has a fine and relatively uniform cell structure.
