Discharge and Sediment Transport in the Field
In this quantitative field activity, students collect field data on channel geometry, flow velocity, and bed materials. Using these data, they apply flow resistance equations (Manning and the depth slope product) and sediment transport relations (Shields curve) to estimate the bankfull discharge and to determine if the flow is sufficient to mobilize the bed. This activity requires students to utilize theoretical and empirical equations derived in class in the context of a field problem. Learning
Michael Mauboussin on the ‘Success Equation’
How do we know which of our successes and failures can be attributed to either skill or luck? That is the question that investment strategist Michael J. Mauboussin explores in his book The Success Equation: Untangling Skill and Luck in Business, Sports, and Investing. Wharton management professor Adam M. Grant recently sat down with Mauboussin to talk about the paradox of skill, the conditions for luck and how to avoid overconfidence. (Video with transcript)Author(s):
Columbia River Basalt Group, Washington, Oregon, and Idaho
This resource describes the Columbia River Basalt Group. The site features brief discussions of the stratigraphy and age of the group, as well as the group's vent system, volumes and eruption rates, and magma supply rates. This CRBG description is an excerpt from the ICG Field Trip T106: Cenozoic Volcanism in the Cascade Range and Columbia Plateau, Southern Washington and Northernmost Oregon: American Geophysical Union Field Trip Guidebook T106, p.21-24.

Behaviour, Decisions and Markets: module syllabus
Module outline for a course on Behaviour, Decisions and Markets, as taught by Miguel A. Fonseca and Dieter Balkenborg, University of Exeter. The aim of this module is to enable students to examine economic theory from a behavioural perspective, and highlight instances where standard economics predicts actual choices correctly and instances where it does not. Students will be introduced to recent behavioural theories that have emerged to explain the empirical observations, and will discuss the im
Cu 21, Sn 79 (wt%), peritectic transformation
This microstructure is generated via a peritecticÃ¢â‚¬Â²s reaction (L+ÃŽÂµ = ÃŽÂ·), which bears some similarities to the more familiar eutectic reaction (L = ÃŽÂ±+ÃŽÂ²). Upon cooling from the liquid phase field, primary ÃŽÂµ is formed, which can be seen here as a slightly darker phase than the sheath of ÃŽÂ· surrounding it. The ÃŽÂ· sheath is the product of a peritectic reaction between ÃŽÂµ and liquid. The peritectic reaction rarely goes to completion, si
Fe, C 0.3 (wt%) steel, spheroidised carbide
A hypoeutectoid alloy (composition less than eutectoid). The first phase formed upon cooling from the austenite phase field is proeutectoid ferrite. Due to the lower solubility of carbon in ferrite, carbon is partitioned into the remaining austenite. At the eutectic point the remaining carbon-enriched austenite transforms to pearlite (a mixture of ferrite and cementite), which is the darker region of the micrograph. The proportion of pearlite is dependent upon the overall composition.Subsequent
As-cast wrought-grade aluminium alloy
The micrograph shows Al-Mg-Fe-Si containing < 1wt.% of each solute. No addition of grain refinement particles (e.g. TiB2). This micrograph illustrates one of the possible growth morphologies that a solidifying metal can adopt (c.f. micrograph 712). The dendritic structure is the result of instabilities in the solid-liquid interface during growth due to the rejection of solute into the liquid phase. Dendritic grains are more prevalent in alloys of high solute content and larger grain sizes.The Ba
Optical Tweezers and Applications
Did you ever imagine that you can use light to move a microscopic plastic bead? Explore the forces on the bead or slow time to see the interaction with the laser's electric field. Use the optical tweezers to manipulate a single strand of DNA and explore the physics of tiny molecular motors. Can you get the DNA completely straight or stop the molecular motor?
Lecture 5: William Froude - A Sacred Duty to Doubt
David Brown on "William Froude - A Sacred Duty to Doubt". William Froude was born in 1810, and in 1861 published the first theory of ship rolling. This led to studies of powering. Using models he showed that there was no one ideal form and models tested at the corresponding speed could predict accurately the performance of ships; the basis of all later tank testing.

Internet Technology and Lifelong Learning
This is a text version of an online distance-learning course produced in 2004. It is deposited here now (July 2009) for archive purposes. It was originally intended for the professional development of staff involved in any way with the management, design and delivery of lifelong learning. It may be of interest to producers of new courses in this field, or to future historians of technology, or simply to educators who may like to be reminded of how different things were in 2004.

Internationalising the Curriculum: an annotated bibliography
This annotated bibliography comprises a selection of books, journal articles, conference papers and other resources on the subject of the internationalised curriculum. It has been compiled initially from a library of global sources originally brought together as part of the review of literature in the field, commissioned by the Higher Education Academy in 2006 (Caruana, V. and Spurling, N., 2007). This has been up-dated to include more recent work. The central criterion for selection of material
Internationalisation good practice: The inclusive curriculum and ‘Internationalisation at Home’
This theme includes papers and articles which explore the meanings attributed to key phrases and attempt to define key concepts within the field of internationalisation as it relates specifically to learning, teaching and assessment practice and curriculum design and delivery in higher education. Many contributions provide concrete examples of activities to support multicultural learning and embed international dimensions in curricula. The student voice is apparent in research that engages stude
14.147 Topics in Game Theory (MIT)
This course/workshop aims to provide an invigorating intellectual environment for graduate students and junior faculty who are interested in economic theory. We will discuss research ideas and explore topics in game theory and more broadly in economic theory.
1.1.5 Late-onset single-gene disorders An individual might know that a late-onset disease such as Huntington's disease (HD) is present in their immediate family and that they might have inherited the disease gene(s). The problems of genetic testing for HD revolve around the fact that it is pre-symptomatic. One dilemma is the long delay between testing positive and developing the clinical symptoms of the disorder in middle age. Is it better not to know and live in hope, or as one victim cried ‘get it over, I'm so tir
