TALAT Lecture 3504: Impact Extrusion Design Aspects and Properties
This lecture describes the forms and shapes which can be fabricated by impact extrusion; it points out limiting factors in the freedom of design of impacts; it helps to learn about the factors affecting tolerances and surface roughness of impacts. Basic knowledge about the formability of metals and background in mechanical engineering is assumed.
TALAT Lecture 3502: Impact Extrusion Processes
This lecture describes the impact extrusion processes as well as the forces and deformations acting on the tools and work-piece in order to give insight into the relation between part design, process and tooling. Basic knowledge about the formability of metals and background in mechanical engineering is assumed.
TALAT Lecture 3505: Tools for Impact Extrusion
This lecture provides knowledge about design philosophy and tool materials for impact tools, which are a cost factor and eminently important for successful impact extrusion. Basic knowledge about the formability of metals and background in mechanical engineering is assumed.
High Impact Polystyrene (HIPS)
High impact polystyrene (HIPS) or 'rubber-toughened polystyrene' is a two-phase mixture of polybutadiene (a synthetic rubber) in polystyrene. The two phases are immiscible, with polybutadiene crystallising out of the melt to form spheroidal particles. In fact, polystyrene is the first phase to crystallise, forming even an even finer dispersion of polystyrene particles which become trapped within the polybutadiene when a phase inversion occurs at around 10% solidification.

Notched zinc, broken by impact at room temperature
This is a notched zinc specimen broken by impact at room temperature. It has failed by a cleavage mechanism. One can observe the cleavage planes clearly separated by regions of local shear, where the fracture path crosses to adjacent planes. The cleavage planes are atomically flat and are not associated with much plastic deformation. At low temperature metals having b.c.c. and h.c.p structures have insufficient independent slip systems operating and are brittle, fracturing by cleavage.

Contemporary French culture in a global context
This is a module framework. It can be viewed online or downloaded as a zip file.
As taught in Semester two 2009.
This module looks at aspects of contemporary French culture in the context of an increasingly globalised culture and economy. In part, the module explores recent attempts to defend, redefine and interpret key aspects of French identity and culture as a means of negotiating ways of living in an era of globalisation and changing social structures.
The module focuses on aspects of eve

The Wonders of the Hydrological Cycle (and Human Impact)
The Hydrologic Cycle (or the Water Cycle) is a cycle of evaporation, evapotranspiration, precipitation and infiltration. (02:18)
The sun heats bodies of waters such as oceans and lakes, which causes the water to evaporate and form water vapor. Water vapor is also transpired from trees and soil. The collection of water vapor condenses to form clouds, which move around the globe by air currents. With the right conditions, clouds precipitate; some of the water absorbs into the ground t
Doing the right thing : corporate social responsibility in a global marketplace
Globalisation, mass consumer awareness and public accountability are all factors in persuading companies to adopt ethical policies. As companies become more accountable not only for their own actions but for those within their supply chain, they have to adapt to ensure success within the context of the global society they operate in. Professor Jeremy Moon (Professor of Corporate Social Responsibility at the University of Nottingham Business School and Director of the International Centre for Cor
Living in an era of global terror
In this podcast, Professor Richard Aldrich from the School of Politics and International Relations, discusses the impact of globalisation, the opportunities this affords to global terrorists and the challenges faced by the intelligence services. Globalisation has led to a free flow of money, people and ideas, which has benefited many people in the West in recent years and enhanced our standard of living, but the price paid is a reduction in security. As we see a shift towards a de-regulated glob
Researching solutions to global water shortages
Director of the University of Nottingham’s Centre for Clean Water Technologies. Making sure the world’s population has enough drinking water is one of the biggest challenges we face today. A rapidly increasing global population, the fact that only a very small percentage of global water is available for consumption and an uneven global distribution of clean drinking water are the main problems in regard to the current global water crisis. Professor Hilal discusses these problems and some of

Researching Skills for Practical Course Students
This course is for use by Academic staff to adapt for their under-graduate students. Originally designed for Art, Media and Design students the idea behind these resources is to address the perceived discrepancy between what students on ‘creative’ courses do in the studio - hands on making - and the academic skills they have to master in order to develop graduate attributes. The approach makes use of the straight-forward delivery method of a lecture, something the students usually expect and
Screening
This comprehensive yet succinct module on screening will help the experienced practitioner to expand their teaching methods, and it will get the novice up to speed on the evaluation and delivery of screening. The first part covers evidence about screening, and the second part comprises four further chapters covering skills relating to application of this evidence in daily practice.
