It has long been the received wisdom that television drama has become increasingly ‘filmic’ in orientation, moving away from the ‘theatrical’ as its point of aesthetic reference. This development, which is associated with the rejection of the studio in favour of location shooting – made possible by the increased use of new technology in the 1960s – and with the adoption of cinematic as opposed to theatrical genres, is generally regarded as a sign that the medium has come into its own. By examining a key ‘moment of change’ in the history of television drama, the BBC ‘Wednesday Play’ series of 1964 to 1970, this article asks what was lost in the movement out of the studio and into the streets, and questions the notion that the transition from ‘theatre’ to ‘film’, in the wake of Ken Loach and Tony Garnett's experiments in all-film production, was without tension or contradiction. The discussion explores issues of dramatic space as well as of socio-cultural context, expectation, and audience, and incorporates detailed analyses of Nell Dunn's Up the Junction (1965) and David Mercer's Let's Murder Vivaldi (1968). Madeleine MacMurraugh-Kavanagh is the Post-Doctoral Research Fellow on the HEFCE-funded project, ‘The BBC Wednesday Plays and Post-War British Drama’, now in its third year at the University of Reading. Her publications include Peter Shaffer: Theatre and Drama (Macmillan, 1998), and papers in Screen, The British Journal of Canadian Studies, The Historical Journal of Film, Radio and Television, and Media, Culture, and Society. Stephen Lacey is a lecturer in Film and Drama at the University of Reading, where he is co-director of the ‘BBC Wednesday Plays’ project.

Solar energy is an inexhaustible and renewable energy without environmental pollution. Solar energy can be used in three kinds of forms: solar thermal energy, photochemical conversion and photovoltaic power generation. Among these, the final form of photovoltaic power generation is electricity which can be transported, applied and stored conveniently. On the basis of photovoltaic effect, solar cell is developed as a new technology to convert light energy into electrical energy using semiconductor. Up to now the two key problems of the development of solar cells are how to improve the conversion efficiency and reduce cost. Therefore, the material and production technology used for solar cells are discussed based on improving conversion efficiency in this article.

Detecting natural gas leaks from the worlds nearly 5 million kilometers of underground pipelines is a difficult and costly challenge. Existing technologies are limited to ground deployment and have a number of limitations such as slow response, false leak readings and high costs. Various remote sensing solutions have been proposed in the past and a few are currently being developed. This paper starts by describing the remote sensing concept and then will focus on a new technology developed by Synodon scientists. This airborne instrument is a passive Gas Filter Correlation Radiometer (GFCR) that is tuned to measure ethane in the 3.3 microns near-infrared band. With its target natural gas column sensitivity of 50 μm, the instrument is capable of detecting very small leaks in the range of 5–10 cuft/hr in winds that exceed 6 miles/hr. The paper concludes with a description of the service which Synodon will be offering to the transmission and distribution pipeline operators using the new technology.

The ejection test technology is studied in a sub-transonic supersonic wind tunnel using a single cylinder to provide ejection velocity. The angular velocity adjusting device of ejection mechanism is designed, which can adjust the ejection velocity and angular velocity of the model independently. When the ejection cylinder moves downward, the angular velocity adjusting mechanism works at the same time, so that the model has the preset ejection velocity and angular velocity at the moment of leaving the ejection frame. The ejection velocity error is less than 5%, the angular velocity error is less than 10%, and the repetition rate is more than 95%. The new technology has been verified by wind tunnel tests under complex aerodynamic conditions of sub-transonic supersonic and multi-body interference. All parameters have reached or surpassed the existing technical specifications. It has served for model tests many times and met the needs of wind tunnel test research on ejection of embedded weapons in aircraft.

Suncor Energy Inc. contacted Synodon as part of an effort to enhance pipeline leak detection. Ideally, Suncor needed a technology that could detect natural gas as well as liquid hydrocarbon releases. Synodon’s new technology is an aircraft mounted gas remote sensing instrument that has been used for detecting leaks from natural gas pipelines for over four (4) years and was expanding their capability to include liquid hydrocarbons. This paper will describe the steps that Suncor and Synodon have taken over the last two years to develop and validate this detection technology. Synodon completed a number of studies including laboratory and field tests that demonstrated the ability of Synodon’s technology to remotely detect ground-level plumes of vapours released from a liquid hydrocarbon pipeline. Synodon conducted full atmospheric analytic modeling followed by laboratory measurements to determine the level of sensitivity of its instrument measurement to both methane and various liquid hydrocarbon vapors including gasoline, condensates and synthetic crude oil. Suncor participated in the development of test methodology and field execution in order to witness and validate the results. Based on this work, Suncor has determined an optimum inspection frequency based on theoretical spill size, SCADA leak detection thresholds and conventional aerial patrol constraints. The results and conclusions of this work will be presented.
