Cu 21, Sn 79 (wt%), peritectic transformation
This microstructure is generated via a peritectic′s 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, 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?
OPSE 402: High Power Laser and Photonics Applications
Open to all engineering, computer science, biology, and science majors with junior or senior standing. Advanced combined laboratory and lecture course emphasizing photonics and high power laser applications. The lecture and laboratory portions of the course focus on the different specialities of the associated faculty in which each faculty member designs the experiment/supporting lecture in their field of expertise. Topics include Maxwell's equations, principles of lasers, electro-optics, non-li
PTC 604: Communication Theory and Research
This course reviews major theories of communication and provides strategies for theory-based research in the field of Professional and Technical Communication. The course focuses on the following research methods: problem statement and hypothesis formulation derived from theory; research design and data generation; existing information sources and their acquisition; and analytic techniques. Our goal in the course is to allow students to develop analytic methods--drawn from traditions in both the
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

6.728 Applied Quantum and Statistical Physics (MIT)
6.728 is offered under the department's "Devices, Circuits, and Systems" concentration. The course covers concepts in elementary quantum mechanics and statistical physics, introduces applied quantum physics, and emphasizes an experimental basis for quantum mechanics. Concepts covered include: Schrodinger's equation applied to the free particle, tunneling, the harmonic oscillator, and hydrogen atom, variational methods, Fermi-Dirac, Bose-Einstein, and Boltzmann distribution functions, and simple
21F.010 Introduction to European and Latin American Fiction (MIT)
This subject serves as a broad introduction to the field of European and Latin American fiction. It is taught in an historical manner—beginning with the first picaresque novel, Lazarillo de Tormes, and ending with contemporary European fiction. It is designed to help students acquire a general understanding of major fictional modes-from 18th century epistolary fiction, Liaisons dangereuses, to 20th century avant-garde fiction: Cosmicomicsi and Aura. Attention is paid not only to the literar
11.301J Introduction to Urban Design and Development (MIT)
This course examines both the structure of cities and ways they can be changed. Its scope includes historical forces that have produced cities, models of urban analysis, contemporary theories of urban design, and implementation strategies. Core lectures are supplemented by discussion sessions focusing on student work and field trips. Guest speakers present cases involving current projects illustrating the scope and methods of urban design practice.
