White cast iron, subject to slow heating and cooling treatment
An example of a white cast iron, so named due to its relatively low carbon content, which means that the carbon present is in the form of cementite. Upon cooling the melt initially forms austenite and subsequently graphite. Upon reaching the eutectoid temperature the austenite transforms to pearlite, giving a final microstructure consisting of graphite in a pearlite matrix.
White cast iron, annealed to precipitate out carbon
A cast iron with a relatively low carbon content. The sample has been normalised at 900 °C for 72 hours. This causes the carbon in the pearlite to precipitate out, leaving graphite in a ferritic matrix.
Comparison of Designers? Modeling Approaches During Architectural Design Process
This study has been started as a part of a research, related to exploring impact of novel interfaces during collaborative architectural design process on designers? way of thinking. However, in this paper it is intended to focus on how the input devices reflect on designers? modeling behavior in computer environment. Therefore it is intended to compare designer?s modeling approaches in computer environment via a case study. Four master students in architectural design computing graduate program
Pearlitic malleable cast iron
A cast iron with a relatively low carbon content. The sample has been normalised at 900 °C for 72 hours in order to refine the grain size. The microstructure consists of pearlite with graphite.
Bone china (with sensitive tint plate)
China clay consists mainly of SiO2 and Al2O3, and is valued for its whiteness (which is due to the low iron oxide content). Bone consists mainly of hydroxyapatite, Ca5(PO4)3OH, and the source supply is mainly ox bone.
Bone china, showing the glaze on the surface (with sensitive tint plate)
China clay consists mainly of SiO2 and Al2O3, and is valued for its whiteness (which is due to the low iron oxide content). Bone consists mainly of hydroxyapatite, Ca5(PO4)3OH, and the source supply is mainly ox bone. The glaze is mostly SiO2, and is applied to render the surface impermeable to liquids and gases, to provide a readily cleanable surface which protects the china, and to provide an aesthetically pleasing coating.
Feature clusters for online recognition of graphic units in drawings
Automated recognition of sketch drawings can provide the means for a natural interface between the designer and a design support system. Sketch drawing recognition is knowledge-intensive in the sense that the system must know what to look for in a drawing. In earlier work, we identified 24 different types of representations, termed graphic units. For recognition of graphic units we combine a multi-agent approach and online recognition. Each agent is specialised for one graphic unit. It continuou
Revision -- Going for Excellence
Producer (requires Internet Explorer). This RLO builds on the ones on preparation and suggests how to add additional comments to well-prepared exam answers, that will maximize success. The advice is based on the work in the book again, and follows a survey of typical assessment criteria in HE. The video displays visual analogies to the content, and there is an 'easy listening' pop music track.
"Environmental Disaster in the Marshes of Southern Iraq"
Josh Ellis has an M.A. in Middle Eastern Studies/Public Policy, University of Chicago. There is little doubt that climate change, deforestation, erosion, and the unequal distribution of natural resources around the globe are of pressing importance everywhere, but these problems are perhaps most acute in Asia, home to 64 percent of the world’s population. Much of this population (1 and 1.3 billion, respectively) is concentrated in India and China, two countries with rapidly growing economies,
Come over to the Flipside... The Flipside is a popular monthly screening slot at BFI Southbank and a pioneering DVD and Blu-ray publishing strand designed to revisit and reappraise weird and wonderful British films that have slipped through the cracks of cinema history. Films that were overlooked, marginalised, or undervalued at the original time of release, or sit outside the established canon of recognised classics. For more information on upcoming Flipside screenings at BFI Southbank: http:

Earth Systems, an Earth Science Course (CA Textbook)
The following course contains assignments and analysis for an Open Source Earth Science course for grades 9 - 10. The collection has been prepared from resources contributed by teachers and partner educational organizations on Curriki, an online community for creating and sharing open source curricula. The Open Source Earth Science course has been organized to meet the CA Science Standards for Earth Sciences in grades 9 - 10, as adopted by the California State Board of Education. This digital

Open for learning
This xerte on-line toolkits resource has been produced as part of the JISC funded BERLiN (Building Exchanges for Research and Learning in Nottingham) project run by The University of Nottingham from April 2009 - April 2010. The project aimed to publish and share the equivalent of 360 credits of Open Educational Resources (OERs), enhance and expand Nottingham's existing Open Educational Repository (U-Now) and foster OER use and reuse. This open educational resource aims to share knowledge gain
Mythology in German literature "Medea"
This is a module framework. It can be viewed online or downloaded as a zip file. As taught in Spring Semester 2010. We are surrounded by materials from and references to ancient mythology: we talk about the Oedipus-complex, name spaceships Apollo and powerful detergents Ajax, have songs about Cupid drawing back his bow and associate Oedipus with Freud rather than Sophocles, Ulysses with James Joyce rather than Homer. Literature, in particular, uses ancient mythology as a rich source to describ
Introduction to microeconomics
This is a module framework. It can be viewed online or downloaded as a zip file. As taught Semester 1 2009/2010. There are no pre-requisites to taking this module and in particular there is no assumption of any prior knowledge of economics. For those who have taken A-level economics or any other version of economics some of the module content will appear familiar to you. However, the methods of analysis and the approach to teaching will quite probably be very different to anything experienced

21A.348 Photography and Truth (MIT)
Still photography, a practice and form of expression that has worked its way into every facet of social life and every culture in the world, is considered here from the perspectives of history and social science. We will discuss the uses and functions of pictures; how they are to be understood and interpreted; whether they have clear-cut content and meanings; how they shape and are shaped by politics, economics, and social life.
