Identification of industrial sources of airborne heavy metal pollution in urban areas

The research examines the deposition of airborne particles which contain heavy metals and investigates the methods that can be used to identify their sources. The research focuses on lead and cadmium because these two metals are of growing public and scientific concern on environmental health grounds. The research consists of three distinct parts. The first is the development and evaluation of a new deposition measurement instrument - the deposit cannister - designed specifically for large-scale surveys in urban areas. The deposit cannister is specifically designed to be cheap, robust, and versatile and therefore to permit comprehensive high-density urban surveys. The siting policy reduces contamination from locally resuspended surface-dust. The second part of the research has involved detailed surveys of heavy metal deposition in Walsall, West Midlands, using the new high-density measurement method. The main survey, conducted over a six-week period in November - December 1982, provided 30-day samples of deposition at 250 different sites. The results have been used to examine the magnitude and spatial variability of deposition rates in the case-study area, and to evaluate the performance of the measurement method. The third part of the research has been to conduct a 'source-identification' exercise. The methods used have been Receptor Models - Factor Analysis and Cluster Analysis - and a predictive source-based deposition model. The results indicate that there are six main source processes contributing to deposition of metals in the Walsall area: coal combustion, vehicle emissions, ironfounding, copper refining and two general industrial/urban processes. |A source-based deposition model has been calibrated using facctorscores for one source factor as the dependent variable, rather than metal deposition rates, thus avoiding problems traditionally encountered in calibrating models in complex multi-source areas. Empirical evidence supports the hypothesised associatlon of this factor with emissions of metals from the ironfoundry industry.

Industrial new product planning:a study of the sources of new product ideas and the development of new product proposals in the UK computer industry

This thesis presents a study of the sources of new product ideas and the development of new product proposals in an organisation in the UK Computer Industry. The thesis extends the work of von Hippel by showing how the phenomenon which he describes as "the Customer Active Paradigm for new product idea generation" can be observed to operate in this Industry. Furthermore, this thesis contrasts his Customer Active Paradigm with the more usually encountered Manufacturer Active Paradigm. In a second area, the thesis draws a number of conclusions relating to methods of market research, confirming existing observations and demonstrating the suitability of flexible interview strategies in certain circumstances. The thesis goes on to demonstrate the importance of free information flow within the organisation, making it more likely that sought and unsought opportunities can be exploited. It is shown that formal information flows and documents are a necessary but not sufficient means of influencing the formation of the organisation's dominant ideas on new product areas. The findings also link the work of Tushman and Katz on the role of "Gatekeepers" with the work of von Hippel by showing that the role of gatekeeper is particularly appropriate and useful to an organisation changing from Customer Active to Manufacturer Active methods of idea generation. Finally, the thesis provides conclusions relating to the exploitation of specific new product opportunities facing the sponsoring organisation.

An investigation to determine the influence of illumination sources on colour discrimination in normal subjects and smokers

Accurate colour vision testing requires using the correct illumination. With the plethora of 'daylight' lamps available, is there a cost-effective alternative to the discontinued MacBeth Easel lamp? Smoking is a known risk factor for macula degeneration. As the macula is responsible for colour discrimination, any toxin that affects it has the potential to influence colour discrimination. Aims: To find a costeffective light source for colour vision testing. To investigate the effect of smoking on colour discrimination. To explore how deuteranomalous trichromats compare with normal trichromats. Methods: Using the Ishihara colour vision test subjects were classified into the groups: 'Normal/Control', 'Smoker/Test', and 'Case Study' (subjects who failed the screening test and did not smoke). They completed the Farnsworth Munsell 100 Hue test under each of the three light sources: Phillips EcoHalo Twist (tungsten halogen - THL), Kosnic KCF07ALU/GU10-865 (compact fluorescent- CFL), and Deal Guardian Ltd. GU103X2WA4B-60 (light-emitting diode - LED) Results: 42 subjects took part in the study: 18 in the Normal/Control group, 18 in the Smoker/Test group, and 6 in the Case Study group. For the Normal/Control group the total error scores (TESs) were significantly lower with the CFL than with the THL (p = 0.017) as it was for the Case Study group (p = 0.009). No significant differences were found between the Normal/Control group and the Smoker/Test group for each light source. Decision tree analysis found pack years to be a significant variable for TES. Discussion: All three light sources were comparable with previous studies. The CFL provided better colour discrimination than the LED despite them both being 6500 K. Deuteranomalous trichromats showed a greatest deviation than normal trichromats using the LED. Conclusions: The Kosnic KCF07ALU/GU10-865 is a cost-effective alternative for colour vision testing. Smoking appears to have an effect on colour vision, but requires further investigation.

The framework of the virtual laser tracker - A systematic approach to the assessment of error sources and uncertainty in laser tracker measurement

Laser trackers have been widely used in many industries to meet increasingly high accuracy requirements. In laser tracker measurement, it is complex and difficult to perform an accurate error analysis and uncertainty evaluation. This paper firstly reviews the working principle of single beam laser trackers and state-of- The- Art of key technologies from both industrial and academic efforts, followed by a comprehensive analysis of uncertainty sources. A generic laser tracker modelling method is formulated and the framework of the virtual tracker is proposed. The VLS can be used for measurement planning, measurement accuracy optimization and uncertainty evaluation. The completed virtual laser tracking system should take all the uncertainty sources affecting coordinate measurement into consideration and establish an uncertainty model which will behave in an identical way to the real system. © Springer-Verlag Berlin Heidelberg 2010.

The Ecumenical movement and the making of the European Community

The European Community has largely been considered a predominantly secular project, bringing together the economic and political realms, while failing to mobilise the public voice and imagination of churchmen and the faithful. Drawing on a wide range of archival sources, this is the first study to assess the political history of religious dialogue in the European Community. It challenges the widespread perception that churches started to engage with European institutions only after the 1979 elections to the European Parliament, by detailing close relations between churchmen and high-ranking officials in European institutions, immediately after the 1950 Schuman Declaration. Lucian N. Leustean demonstrates that Cold War divisions between East and West, and the very nature of the ecumenical movement, had a direct impact on the ways in which churches approached the European Community. He brings to light events and issues which have not previously been examined, such as the response of churches to the Schuman Plan, and the political mobilisation of church representations in Brussels, Strasbourg and Luxembourg. Leustean argues that the concept of a 'united Europe' has been impeded by competing national differences between religious and political institutions, having a long-standing legacy on the making of a fragmented European Community.
