Fracture surface in a liquid crystalline polymer, oriented by a magnetic field

Description

Above their melting point, liquid crystalline polymers exhibit a mesophase within which, although able to flow and are not arranged in a crystal, they exhibit long range orientational order. This molecular alignment can be exploited to make high strength and stiffness fibres such as Kevlar, or even mouldable thermotropics such as Vectra. Molecular alignment can also be controlled by an external applied field; a property exploited in liquid crystal displays. This polymer has been subjected to a magnetic field of 1.1T (normal to the fracture plane) for one hour and the resulting alignment is evident in the fractured surface.

'Melete' ready for launch

Description

Crowds gather as the 'Melete' is prepared for launch at at the Deptford Yard of Sunderland Shipbuilders Ltd, 25 April 1975 (TWAM ref. DS.LG/4/PH/4/3). Tyne & Wear Archives is proud to present a selection of images from its Sunderland shipbuilding collections. The set has been produced to celebrate Sunderland History Fair on 7 June 2014. It's a reminder of the thousands of vessels launched on the River Wear and the many outstanding achievements of Sunderland?s shipyards and their workers. These photographs reflect Sunderland?s history of innovation in shipbuilding and marine engineering from the development of turret ships in the 1890s through to the design for SD14s in the 1960s. The Sunderland shipbuilding collections are full of fascinating stories. Some of these are represented in this set, such as the ?Rondefjell?, launched in two halves on the River Wear by John Crown & Sons Ltd and then joined together on the River Tyne. The set also shows the vital part that Sunderland?s shipbuilding industry played during the First World War. William Doxford & Sons Ltd built Royal Naval destroyers such as HMS Opal, which served in the Battle of Jutland, while other yards constructed cargo ships to help keep these shores supplied.

CMS.930 Media, Education, and the Marketplace (MIT)

Description

How can we harness the emerging forms of interactive media to enhance the learning process? Professor Miyagawa and prominent guest speakers will explore a broad range of issues on new media and learning - technical, social, and business. Concrete examples of use of media will be presented as case studies. One major theme, though not the only one, is that today's youth, influenced by video games and other emerging interactive media forms, are acquiring a fundamentally different attitude towards media. Media is, for them, not something to be consumed, but also to be created. This has broad consequences for how we design media, how the young are taught in schools, and how mass media markets will need to adjust.

Al 88, Si 12 (wt%), eutectic alloy

Description

This sample is a casting alloy of eutectic composition. From the melt a eutectic is formed between aluminium solid solution and virtually pure silicon. Slow solidification produces a very coarse microstructure. The eutectic comprises large plates of silicon in the aluminium matrix. This microstructure displays poor ductility due to the brittleness of large silicon plates. The microstructure is normally refined through either rapid solidification, which lets the silicon phase assume a fibrous form, or by a process known as modification.It may be noted that primary aluminium dendrites can be seen, although the composition is very close to the eutectic point and an entirely eutectic microstructure might thus have been expected. This effect is a consequence of the strongly skewed nature of th

As cast white cast iron

Description

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 dendrites and ledeburite. The dendrites then transform to pearlite, and the ledeburite to ferrite and cementite.

Can stories change the world? Promises and challenges of web-based patient feedback for improving care

Description

Health Experiences Institute/Management in Medicine (HEXI/MiM) speaker event. Patient experience has become an important currency and resource in contemporary health care management. User satisfaction surveys, focus groups, Patient Experience Trackers (PET), Patient Reported Outcome Measures (PROMS) -- a whole range of technologies have been developed to turn sensations, thoughts and feelings into 'evidence' and useful knowledge. In this seminar, we will have a closer look at one of these technologies: web-based patient feedback. Combining insights from research and practice, we will ask: what does it take to mobilise experience? Can patient stories improve the quality of care? What are the implications? And what issues does this raise for NHS leaders and policy makers? Wales; http://creativecommons.org/licenses/by-nc-sa/2.0/uk/

The Learner Group and Implications for Practice (IMS Content Package)

Description

The Learner Group and Implications for Practice workshop training materials were produced by the Profound and Complex Needs project for Scotland's Colleges. These are available to be used by college teams as you would find appropriate. Originally intended to be run over half a day, in almost all cases they can be split into one or one and a half hour sessions, according to the time available. Each pack contains (a detailed training plan, a PowerPoint presentation, a set of handout materials and other additional resources).

CMS.876 History of Media and Technology: Sound, the Minority Report -- Radical Music of the Past 100 Years (MIT)

Description

This course looks at the history of avant-garde and electronic music from the early twentieth century to the present. The class is organized as a theory and production seminar for which students may either produce audio/multimedia projects or a research paper. It engages music scholarship, cultural criticism, studio production, and multi-media development, such as recent software, sound design for film and games, and sound installation. Sound as a media tool for communication and sound as a form of artistic expression are subjects under discussion. The artists' work reviewed in the course includes selections from audio innovators such as the Italian Futurists, Edgard Varèse, John Cage, King Tubby, Brian Eno, Steve Reich, Afrika Bambaataa, Kraftwerk, Merzbow, Aphex Twin, Rza, Björk, and

Al, Si 12, Na 0.02 (wt%), eutectic alloy - refined microstructure

Description

This sample is a casting alloy of eutectic composition. The microstructure has been refined by modification through the addition of a small amount of sodium to the alloy composition. The large silicon plates have been altered to a more favourable fibrous form, leading to an enhancement of the mechanical properties due to the refinement of the microstructure. There is also a change to a planar interface during solidification, which minimises porosity in the casting.
