Abstract:
In 1947, BBC produces the first radio drama on Don Quixote to celebrate the 400th anniversary of Cervantes’ birth. Released in Spain and Latin America in 27 chapters, BBC defined it as “the most ambitious project ever carried out.” The goal was to enhance BBC reputation in Spain. The radio play had the participation of actors from Radio Madrid, Spanish exiles in London and Latin American professionals. BBC surrounded with experts to adapt Cervantes narrative to radio language; deal with Spanish accents diversity; and compose music, which accompanied this radio version. The Quixote of BBC spread Cervantes’ work throughout all Spanish-speaking countries and promoted the production of other Quixotes within the radio in Spain. Keywords: Radio; Radio Drama; Radio Fiction; Don Quixote; BBC.

Abstract:
The voices of minority ethnic staff working in radio are very rarely heard. In fact, the UK radio industry has been singled out, by the government approved regulatory body, as continuing to fail to reflect the diversity of British communities ‐ both on-air and in terms of employment. This article illustrates the perspectives of minority ethnic workers employed at the BBC on the Asian Network, a specialist ethnic radio station, and examines how they craft programme and news content for a distinctive audience. Through in-depth interviews with 30 BBC employees, there is look at the challenges, conflict and barriers this group of staff face. The interviews expose a difference of opinion among staff over the core target audience and the version of Asian identity articulated on-air and demonstrate that a rigid gatekeeping system restricts the dissemination of news content about all the communities that comprise the group British Asian.

Full text
Abstract:
The 'historical turn' in British Media Studies has yielded new histories of television but little work on the history of post-television radio. This thesis hopes to contribute to that neglected area. The research, based on radio and written archives and interviews with former BBC staff, examines the BBC Radio 4 current affairs programme, Analysis between the years 1970 and 1983. It addresses a number of questions about the programme, including the precise reasons for its creation, how it evolved, and how it covered a range of current affairs topics. In addition, this history of current affairs radio provides useful, new insights into the rise of professionalism in the BBC, the existence of informal networks, impartiality and bias, the tension between elitism and populism and the specificity of current affairs. The thesis includes a full discussion of the history of current affairs radio from 1927 to 1960. In this section the relationship of the literary elite to the BBC in the 1930s is addressed and the evolution of the 'topical talk' and the post-war 'talks magazine' are described. The precise origins of Analysis in the late 1960s are explained with reference to the tension between the more journalistic and populist 1960s news sequences and the elitist and anti-journalistic talks tradition from which Analysis emerged following the publication of Broadcasting in the Seventies. The role of individual presenters of Analysis is examined and the evolution of the form of 'broadcast talk' employed on the programme. There is a chapter on Analysis in Africa and a concluding chapter which evaluates the relationship between Analysis and the emerging political ideology of Thatcherism. By focussing on one programme over a period of time, and following the careers of named individuals who worked in BBC radio, it is possible to reveal conflicting broadcasting values and ideals of professionalism and current affairs and to trace these back to their antecedents in the pre-war BBC.

Abstract:
This thesis aims to explore strands of assemblage, actor network theory and object oriented philosophy to the study of popular culture and world politics. Specifically it focuses on the linkages to be made between radio broadcasting, travel writing and journalism, in light of these theories. It does this through the presentation of series of archival encounters with material relating to BBC radio and foreign news production during the 1960’s Cold War period, an era in which radio broadcasting and radio technologies were absolutely central to the understanding wider geopolitical environments. The opening chapters of the thesis argue for the utility of a version of relational materialist approaches hybridised with discursive analytic frameworks as interlinked ways of thinking, which are more appropriate to understanding radio as a semiotic-discursive hybrid of popular cultural construction, as read through BBC radio and foreign news during the Cold War. The empirical chapters look to a variety of archival texts produced by radio, including infrastructural and network plans, scripted news series and individual biographical archives and turns the tools from the hybrid framework to address them. The thesis then moves towards a further provocation: to imagine radio itself differently, as a geo-political force, and suggests further possibilities for research through engagement with conceptual art, experimental literature and sound recording to conceive of some of the non-representational aspects radio’s multiple fields of relations. The thesis concludes with a call, based on what has gone before, to recognise the importance of networked and assemblage ontologies to understanding further historical and contemporary formations of geopolitical media, and suggests further research based on the strategies it identifies.

Full text
Abstract:
The BBC's women's radio in the British post-war period (1945 – 1955) is still a very much neglected area of historical research, although the BBC after the Second World War continued to produce many talks and programmes that were specifically aimed at women, such as the factual Woman’s Hour (1946) and the fictional Mrs. Dale’s Diary (1948). By building on archival research conducted mainly at the BBC Written Archives Centre, and further work carried out at the Mass Observation Archive, this thesis addresses the production side, as well as the text, and the audience; in a sense a very multifaceted approach. Focus has been laid on women's programmes such as Woman’s Hour and Mrs. Dale’s Diary. But other talks and discussions have also been considered not necessarily with just a focus on women. Throughout the research the editorial process has been of major interest; the thinking behind; the production process. The thesis will demonstrate the importance played by BBC women's programmes in this period but also in the general development of British broadcasting. The thesis also offers a detailed insight into the internal culture of the BBC, and its women's programmes, at a time when questions about culture and taste were surfacing. The thesis will therefore be an original contribution to knowledge to British broadcasting history, but due to its interdisciplinary nature using radio as a 'Historian', this work is further challenging previous assumptions about the post-war housewife, and the perception of the immediate post-war years as a particular stifling and conservative period, with no feminism.

Full text
Abstract:
The story of BBC Local Radio in England, from the days of its conception around 1960, through to the launch of the first stations in 1967 and the finalisation of how to complete the chain in 1980 is a neglected area of research in media history. This thesis tells this story, using previously undocumented research from the BBC Written Archive Centre, and supplemented by oral history interviews with key participants. The approach is multi-faceted. Part of the investigation lies in gaining a greater understanding of how the BBC operated as an institution during these years. The internal culture of the BBC presents a series of complex issues, and the evolution of local radio illustrates this in many ways, in matters concerning management, autonomy, technology, the audience and finance. Linked to this are the differing notions and definitions of what „local‟ meant, in terms of the original concept and the output in practice. For local radio, this had a crucial impact on station location, the size of the transmission area and the degree to which the stations were able to represent and embody their communities. This history also assesses the impact the stations made, often in contrast to the popular image and perception of local broadcasting. The original contribution to knowledge that this thesis makes is in narrating this history for the first time, and in doing so, challenging previous assumptions about the nature of local broadcasting as part of the BBC and as part of the wider community.

Abstract:
In the 1980s the future of public service broadcasting in Britain was called into doubt. Technological developments in cable, satellite and digital technologies were, it was argued, poised to end the condition known as 'spectrum scarcity'; while the emergence of a neo-liberal Conservative government, pledged to rolling back the frontiers of the state', was of the opinion that the current system of public service broadcasting provision was no longer necessary given the number of broadcasting channels now available; broadcasting, in its view, would increasingly be able to mirror the publishing industry in its structure and future regulation. Critics however, were loathe to accept the argument that technological considerations alone ought to drive broadcasting policy; and two key questions emerged. Firstly, how was public service broadcasting to be defended in a climate increasingly hostile to public service ideals and institutions in general; and secondly, and as a result of the first question, how was public service broadcasting to be understood? This thesis seeks to answer both these questions and argues that in the process of clarifying the nature of public service broadcasting in the past, that solutions for its defence in the future will be found. Public service broadcasting, was not, it will be argued, simply about institutions like the BBC, but evidence of a much broader and widely shared (across the political divides) understanding of the proper role of broadcasting in a democratic society (at least until the 1980s). In short, public service broadcasting in the past was never simply a response to a set of technological conditions; instead it was forged from a set of political, economic, Administrative and cultural ideas about the nature of society and broadcasting's role in it; and hence its ability to respond to the new conditions of the 1990s and beyond.

"Correlating Physical Chemistry with Interfacial Properties: Effect of Salinity on the Partitioning, Distribution and Performance of a Quaternary Amine Corrosion Inhibitor." In CONFERENCE 2023. NACE International, 2023. https://doi.org/10.5006/c2023-19142.

Full text
Abstract:
Abstract Corrosion inhibitors provide a cost effective method for internal corrosion control of carbon and low alloy steel infrastructure within the oil and gas industry. The correct selection and validation of inhibitors is essential to ensure successful, safe and reliable operation of infrastructure. Despite a consensus from operators and chemical suppliers that the fundamental properties dictating inhibitor performance are largely understood, the reality is that an extremely complex relationship exists between the physical properties of surfactants, the environmental solution chemistry and the surfactant adsorption characteristics/performance. To demonstrate the complexity of such interactions, the effect of salinity on the partitioning/distribution behavior of a model quaternary amine corrosion inhibitor molecule (alkyldimethylbenzylhexadecylammonium chloride, or BAC-C16) is explored, with the implications of such behavior determined in the context of interfacial adsorption and inhibition performance. Partitioning experiments were conducted at 30°C and pH 4 between toluene and sodium chloride (NaCl) brine (1:1 ratio) over varying salinities (0.1, 1 and 10 wt.%). The partitioning/distribution characteristics of BAC-C16 were firstly reviewed in the context of the surfactant micellization at each salinity through determination of the critical micelle concentration (CMC) using a lipophilic dye (Nile Red) method. The effect of BAC-C16 partitioning/distribution behavior on corrosion inhibitor performance was subsequently quantified using a series of rotating cylinder electrode (RCE) experiments, before discussing the implications of such observations in the context of field deployment and verification of corrosion inhibitors. The work demonstrates that marginal changes in the physical chemistry (salinity in this instance) can have significant consequences in terms of corrosion inhibitor performance, and consequently, asset integrity.

Abstract:
Abstract The corrosion behavior of carbon steels (L80 and C90) galvanically coupled to corrosion resistant alloys (13% Cr and 22% Cr) has been investigated in a Dynamic Field Tester (DFT) installed at a Gas / Condensate well head located near ANACO, Venezuela, which was producing an average of 270 NM3/min (13.8 MMSCF/D) of gas and 10 1/min (93 bbl/d) of liquid with 50 % water cut. The tests were run for two months at about 0.8 MPa (117 psi) CO2 partial pressure and 85°C. The effect of area ratio was studied at different superficial gas velocities (from 4 to 60 m/s). Results showed that coupling carbon steel samples galvanically to CRA's tended to reduce both uniform and localized corrosion of the carbon steel. The anode/cathode area ratio affects the coupling behavior; and the position of the specimen, relative to the fluid flow, was found to have no significant effect. The decrease in corrosion rates of galvanically coupled carbon steel specimens was related to differences in the composition and properties of the corrosion products, probably due to changes in the kinetics of nucleation and growth of iron carbonate films.

Full text
Abstract:
Abstract The role of grain boundary sensitization on the intergranular Stress Corrosion Cracking resistance of heat affected zones in welded supermartensitic stainless steels have been studied. Slow strain rate tensile tests are performed on specimen sampled across multiple-pass welds. The effects of the carbon content and chromium to carbon ratio on the resistance to Stress Corrosion Cracking are highlighted. The examination of carbon replica in transmission electron microscopy show that these differences are related to the grain boundary coverage by chromium carbides. A sensitisation phenomenon in heat affected zones is proposed as being the primary cause for the sensitivity to stress corrosion cracking. Post-weld heat treatments are a practical solution to this problem and simulated heat treatments demonstrate a time-temperature dependence that is compatible with the kinetics of chromium diffusion in bcc ferrite. The transposition of these results to four-points bend testing is discussed.

Abstract:
The geology of the Montney Formation and the geochemistry of its produced fluids, including nonhydrocarbon gases such as hydrogen sulfide were investigated for both Alberta and BC play areas. Key parameters for understanding a complex petroleum system like the Montney play include changes in thickness, depth of burial, mass balance calculations, timing and magnitudes of paleotemperature exposure, as well as kerogen concentration and types to determine the distribution of hydrocarbon composition, H2S concentrations and CO2 concentrations. Results show that there is first-, second- and third- order variations in the maturation patterns that impact the hydrocarbon composition. Isomer ratio calculations for butane and propane, in combination with excess methane estimation from produced fluids, are powerful tools to highlight effects of migration in the hydrocarbon distribution. The present-day distribution of hydrocarbons is a result of fluid mixing between hydrocarbons generated in-situ with shorter-chained hydrocarbons (i.e., methane) migrated from deeper, more mature areas proximal to the deformation front, along structural elements like the Fort St. John Graben, as well as through areas of lithology with higher permeability. The BC Montney play appears to have hydrocarbon composition that reflects a larger contribution from in-situ generation, while the Montney play in Alberta has a higher proportion of its hydrocarbon volumes from migrated hydrocarbons. Hydrogen sulphide is observed to be laterally discontinuous and found in discrete zones or pockets. The locations of higher concentrations of hydrogen sulphide do not align with the sulphate-rich facies of the Charlie Lake Formation but can be seen to underlie areas of higher sulphate ion concentrations in the formation water. There is some alignment between CO2 and H2S, particularly south of Dawson Creek; however, the cross-plot of CO2 and H2S illustrates some deviation away from any correlation and there must be other processes at play (i.e., decomposition of kerogen or carbonate dissolution). The sources of sulphur in the produced H2S were investigated through isotopic analyses coupled with scanning electron microscopy, energy dispersive spectroscopy, and mineralogy by X-ray diffraction. The Montney Formation in BC can contain small discrete amounts of sulphur in the form of anhydrite as shown by XRD and SEM-EDX results. Sulphur isotopic analyses indicate that the most likely source of sulphur is from Triassic rocks, in particular, the Charlie Lake Formation, due to its close proximity, its high concentration of anhydrite (18-42%), and the evidence that dissolved sulphate ions migrated within the groundwater in fractures and transported anhydrite into the Halfway Formation and into the Montney Formation. The isotopic signature shows the sulphur isotopic ratio of the anhydrite in the Montney Formation is in the same range as the sulphur within the H2S gas and is a lighter ratio than what is found in Devonian anhydrite and H2S gas. This integrated study contributes to a better understanding of the hydrocarbon system for enhancing the efficiency of and optimizing the planning of drilling and production operations. Operators in BC should include mapping of the Charlie Lake evaporites and structural elements, three-dimensional seismic and sulphate ion concentrations in the connate water, when planning wells, in order to reduce the risk of encountering unexpected souring.

Abstract:
The overall objective of this research was to identify chromosomal regions and candidate genes associated with control of concentration and forms of carotenoids (includes pro-Vitamin A) and tocopherols (Vitamin E), which are both antioxidants and are associated with health advantages. Vitamin A and E are included in animal feeding supplements and the eventual goal is to increase levels of these compounds in maize grain so that the cost of these supplements can be reduced or eliminated. Moreover, both compounds are antioxidants that protect unsaturated fatty acids from oxidation and thus maintaining maize oil quality for longer periods. We identified three SSR markers that are associated with 38% of the variation for total carotenoids and three SSR markers associated with 44% of the variation for total tocopherols in the cross W64a x A632. We identified two candidate genes associated with levels of carotenoids: phytoene synthase and zeta carotene desaturase. Evaluation of (Illinois High Oil x B73) B73 BC 1S1 population for tocopherols detected additional chromosomal regions influencing the level of total tocopherols, and detected a common region on chromosome 5 associated with ratio of the more desirable alpha from to the gamma form of tocopherol. The results suggest molecular marker assisted selection for higher levels of these antioxidants in corn grain should be feasible.
