Distance Learning Material
The materials provided are taken from three postgraduate modules which students study as part of the School's distance learning MA degree programmes in 'Literary Linguistics', 'Applied Linguistics, Applied Linguistics and English Language Teaching' and 'Modern English Language'. Our courses generally consist of 10 units which cover the key areas of study within particular disciplines, in conjunction with material documenting the latest developments within each field. The 'Descriptive Linguistic
Hypoeutectoid steel, normalised at 950°C
A hypoeutectoid alloy (carbon 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 eutectoid 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. The

Fe, C 0.3 (wt%) steel, spheroidised carbide

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.

Hypoeutectoid steel, normalised at 1100°C
A hypoeutectoid alloy (carbon 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.

Cu 21, Sn 79 (wt%), peritectic transformation
This microstructure is generated via a peritectic reaction (L+ε = η), which bears some similarities to the more familiar eutectic reaction (L = α + β). Upon cooling from the liquid phase field, primary ε is formed, which can be seen here as a slightly darker phase than the sheath of η surrounding it. The η sheath is the product of a peritectic reaction between ε and liquid. The peritectic reaction rarely goes to completion, since the formation of η around the ε phase separates it from

21L.012 Forms of Western Narrative (MIT)
This class will investigate the ways in which the formal aspects of Western storytelling in various media have shaped both fantasies and perceptions, making certain understandings of experience possible through the selection, arrangement, and processing of narrative material. Surveying the field chronologically across the major narrative genres and sub-genres from Homeric epic through the novel and across media to include live performance, film, and video games, we will be examining the ways in
14.581 International Economics I (MIT)
This course provides a graduate-level introduction to the field of international trade. It examines the theory of international trade and foreign investment with applications in commercial policy. Topics include gains from trade, Ricardian models of technological differences, Heckscher-Ohlin models of factor endowment differences, intermediate input trade, wage inequality, imperfect competition, firm heterogeneity, multinational firms, international organization of production, dynamics, trade po
Intro to Instructional Design
Instructional technology is a systematic way of designing, developing, implementing, and evaluating the processes of learning and teaching with specific objectives based on research in human learning and communication. It employs a combination of human and nonhuman resources to bring about more effective instruction. Instructional technology includes aspects of instructional design, product development, interactive learning technologies, multimedia, distance education, and library and informatio
USGS Materials Maps
Visitors can learn about the relatively new field of imaging spectroscopy, which allows specific absorption features, caused by chemical bonds in materials, to be mapped spatially. Topics include an introduction to the procedure, environmental applications, vegetation and biota mapping, lithologic, and mineral mapping. A set of links provides access to reports, accompanied by spectroscopic images, on the use of this new tool in chosen locations.
Superspace: One Thousand and One Lessons in Supersymmetry
We introduce superfields in chapter 2 for the simpler world of three spacetime dimensions, where superfields are very similar to ordinary fields. We skip the discussion of nonsuperspace topics (background fields, gravity, etc.) which are covered in following chapters, and concentrate on a pedagogical treatment of superspace. We return to four dimensions in chapter 3, where we describe how supersymmetry is represented on superfields, and discuss all general properties of free superfields (and the
Exploring Sustainability in Agriculture: An Online Sustainable Agriculture Instructional Resource
Growing interest in sustainable agriculture has generated a wealth of educational materials on the many social, environmental, and agronomic topics related to this expanding field.
In creating this online resource, we’ve reviewed hundreds of resources—textbooks, popular books, web sites, videos, PowerPoint presentations, and more—to identify the highest-quality and most relevant materials on sustainable agriculture available. Whether you’re teaching a 2-hour community gardening workshop
Exploring Magnetism
The goal of this unit is for students to develop a deeper understanding of electromagnetism through inquiry based activities. The first session in the guide is designed to teach students that magnets have an invisible force field known as a magnetic field, and that this field has an effect that can be measured around a magnet using a compass. The second session is designed to teach students that electricity flowing in wires also creates an invisible magnetic field that can also be measured using
The restless Universe
The restless Universe introduces you to major achievements and figures in the history of physics, from Copernicus to Einstein and beyond. The route from classical to quantum physics will be laid out for you without recourse to challenging mathematics but with the fundamental features of theories and ...
Charge in Magnetic Field
The EJS Charge In B-Field model allows the user to simulate moving charged particles in two identical magnetic field regions separated by a zero magnetic field gap.
Barrier Scattering model
The EJS Barrier Scattering model shows a quantum mechanical experiment in which an incident wave (particle) traveling from the left is transmitted and reflected from a potential step at x=0. Although the analytic solution to this standard problem is well known, its visualization shows how the incident and reflected waves form an interference pattern and how the incident wave penetrates the classically forbidden region when its energy is less than the barrier height height V0
