TALAT Lecture 1201: Introduction to Aluminium as an Engineering Material
This lecture provides an introduction to metallurgical concepts necessary to understand how structural features of aluminium alloys are influenced by alloy composition, processing and heat treatment, and the basic affects of these parameters on the mechanical properties, and hence engineering applications, of the alloys. It is assumed that the reader has some elementary knowledge of physics, chemistry and mathematics.
TALAT Lecture 3207: Solidification Defects in Castings
This lecture provides an introduction to the causes and remedies of the main solidification defects in castings. The students should be able to diagnose the major defects in castings and propose methods of preventing them. Basic knowledge of physics and foundry practice is assumed.
Slip by dislocation glide
Animation of slip by dislocation glide. Dislocation glide allows plastic deformation to occur at a much lower stress than would be required to move a whole plane of atoms past another. See also the bubble raft experiment (videos 17 and 18). From TLP: Introduction to dislocations, http://www.msm.cam.ac.uk/doitpoms/tlplib/dislocations/dislocation_glide.php
Anisotropic dielectric permittivity: tetragonal-cubic phase transition in barium titanate
A thin section of barium titanate is viewed between crossed-polars, Initially, the sample is below the transition temperature, and since the domains of the anisotropic tetragonal phase exhibit birefringence, it is brightly coloured when viewed between crossed-polars. When the sample reaches the transition temperature, the isotropic cubic phase forms, which appears black.

Anisotropic thermal conductivity in quartz: parallel to c-axis section
A section of quartz cut parallel to the c-axis being heated from a point at its centre. An ellipse shows that the thermal conductivity in this plane is direction-dependent. From TLP: Introduction to Anisotropy, http://www.msm.cam.ac.uk/doitpoms/tlplib/anisotropy/thermal.php
Maritime Transportation, Chemistry and Oil
These files outline a general introduction to a joint view of maritime transportation, chemistry and crude oil and petroleum products. They include study material and self evaluation tests, which could be covered in 35 hours. This material is suitable for 1st year undergraduate students enrolled in Nautical or Maritime Engineering Studies, and also for a general audience.
The Changing Workplace
The 20th century ushered in a change from handcrafting to machine tooling. Henry Ford introduced one of the first moving assembly lines as a way to turn out more cars more quickly, and the emerging auto industry popularized this mode. A photo of the Doble Steam Motors Corporation factory shows a line of workers and car chassis in production. This new technology, and the spread of industrialization, changed forever the way that work was completed. A wide variety of industries all across the count
International Classification of Function, Disability and Health
This package was originally designed for undergraduates in Medicine at the University of Nottingham. It will also be useful to students in nursing, allied health professions and pharmacy. Practitioners in these fields, who are new to the ICF, will also find it a useful introduction. It describes the International Classification of Functioning, Disability and Health (ICF), a classification system published by the World Health Organisation to describe health status. This system is widely used in r
Delamination cracks in h-BN particles.
h-BN particles were subjected to compressive stress in the (0001) planes (within a silicon nitride particulate-reinforced silicon carbide composite). The occurrence of BN inclusions results from the introduction of colloidal BN into the hot isostatic pressing process. They are formed from B2O3 present as a thin surface film on the BN particles in the barrier layer. B2O3 will be molten during the pressing process and will diffuse rapidly into the powder compact and react with Si3N4 to form BN. Su
Population and Development
This module on population and development is part of the World Bank Group's educational site that addresses sustainable development in the world. An introduction, objectives, activities, and references are provided. Educators can use the activities to help students understand population growth rates.
Introducing Regional Integration
This course is designed as a general introduction to regional integration, and is particularly aimed at non-specialists. It reviews some of the main definitions of what constitutes a region, and identifies the basic concepts and approaches to integration. The course portrays both the diversity and the hierarchical nature of regionalism, and calls attention to the motivations that lead groups of states and regions to elect for one particular form of regional cooperation over another. The course
Medicine Games: Control of the Cell Cycle
Play a game and find out about a Nobel Prize awarded discovery or work! In this game you are to take on the job as a Cell Division Supervisor. Are you familiar with the different phases in the cell cycle? If not, maybe you should pay extra attention to the image of the cell cycle in the introduction.
This topic starts with a basic introduction to muscles and an image illustrating the possible locations of the different muscle tissues. The three types of muscle tissue are described in more detail. Along with the features of muscle tissue (e.g. contractibility), the functions of these tissues (e.g. support) are discussed.
The Biography of Woodrow Wilson
A short video outlining some of the decisions made by Wilson and his efforts to get the League of Nations passed.
Good Practice Guide in Question and Test Design
This booklet will provide an introduction to good practice in question and test design. It includes the art of using objective tests to assess some aspects of student learning. At the outset you should be aware that objective tests are just one method of assessment. They are useful for assessing knowledge, comprehension and application and in some circumstances can be used to assess higher order skills such as evaluation and synthesis. They cannot be used to assess creativity, integration of ide
Using Portfolio's for Learning and Assessment - A staff handbook
This resource offers guidance for staff on introducing students to portfolios to be used for learning and assessment. It is based on experience gained while working on an FDTL Project “Promoting the Development of key skills through the use of portfolios” (2002 - 2005). The outlined Portfolio Workshops in this handbook have been developed as a result of the Project activities at Leeds Metropolitan University, but are also supported by the findings from the project as a whole. There are 2 acc
Physics in architecture
Developed in 1998 by Dr John Whittle (Department of the Built Environment) using Authorware, this package contains brief interactive notes on eight areas of physics in which architects need a working knowledge. However, it is also useful to others in science, engineering and social sciences looking for an introduction to the topics concerned. These topics are: Units of measurement; Scalar and vector quantities; Newton’s laws; Mass and weight; Action and reaction; Waves; Heat, work and energy;

Prescribing Heroin: the logical next step for Canada?
October 30, 2013 - Panel Discussion Prescribing Heroin explores the questions: what would an ongoing prescription heroin program in Canada look like, and how can we get there? Five years after the NAOMI clinical trial, which confirmed worldwide research demonstrating the effectiveness of prescribing heroin for those chronically dependent drug users who have not responded to other forms of treatment, this health intervention is still not available anywhere in Canada. The panel discussion fol
