A new test facility, with a vertical reflux condenser of 1500mm overall length and 45mm internal diameter, has been commissioned and tested and methods developed for measuring key process parameters. An experimental study of reflux condensation in a single tube using n-pentane and iso-octane and binary mixtures of these single component hydrocarbons has been undertaken. Using water as the cooling medium, a correlation was developed for determining the coolant-side heat transfer coefficient in the reflux condenser based on the Wilson plot method. The composition of binary liquid mixture samples from the test facility was determined using an empirical correlation developed using density measurements from a vibrating u-tube densitometer. The single components were condensed in the range 32.0-48.4°C and 0.106-1.515bara by adjusting the test condenser heat load for fixed conditions on the coolant side to investigate how the condensate-film heat transfer coefficient varied with the condensate film Reynolds number. The results show good agreement with the method recommended by HTFS for correcting the Nusselt theory for the effects of waves. A further small correction was made to improve the fit to the data. The binary hydrocarbon mixtures were condensed across the range 65.9-90.1°C and 0.729-1.531bara by conducting similar experiments where the feed vapour contained 50% and 70% n-pentane. Composition measurements of the condensate and vapour leaving the test condenser were made to examine the separation of components during partial reflux condensation. The results suggest that this separation is influenced by heat flux and that it would be improved if the test condenser were operated at a lower heat flux. Further experimental work is needed to verify this, and to investigate how this influences the number of thermodynamic stages, which was found to be less than one with the conditions reported here. Analysis of the heat transfer resistances on the vapour side showed that the standard procedure of using a dry-gas heat transfer coefficient, with or without a mass transfer correction term based on the film theory, poorly predicted the experimental values. These predictions were improved by the use of an enhancement factor, which may be more relevant in counter-current than co-current condensing situations. The results indicate that use of a dry-gas heat transfer coefficient with the film theory correction factor, over-predicts the mass transfer resistance. Comparison was made between the data and predictions based on the integral condensation curve, as might be used in Silver's method for condenser thermal design. It was shown that this method poorly predicted the surface area and the separation achieved in the test condenser. The results indicate that the heat and mass transfer coefficients obtained in a plain tube are significantly higher than those based on using a dry-gas heat transfer coefficient corrected by film theory. Implications for the design of reflux condensers have been presented.

This research addresses the ways in which film might be used to investigate senses of place and representations of place and ritual. It focuses on two seasonal performative folk traditions in rural England, Haxey Hood in North Lincolnshire and Mayday in Padstow. By considering the experiential qualities of these annual rituals and their significance for local communities as seen in their wider socio-economic contexts, this research raises broader questions regarding place and belonging in contemporary society, and how film as a medium capable of directly conveying phenomenological experience, might transmit the sensual qualities of lived experience, place, and landscape to an audience. Drawing on Sobchack's conception of the film as a body in itself, the role of embodied experience is central in this study in exploring interconnections between the bodies of the filmmaker, the film itself, subjects and audience and their empirical possibilities. The research at the same time is wary of realist approaches to representation, instead seeking to consider the ways in which this “wild meaning” is then manipulated, fragmented and transformed in the process of filmmaking, both ‘in the field’ and in the editing process. Through the use of experimental ethnographic methods, key conceptual aspects of this thesis such as performance, the embodied camera and auto-ethnography are used to investigate the complex ways that place and ritual might not only be known and understood, but are also performed and imagined anew through film. Place and belonging are themes of great contemporary relevance in current academic and art practice, and the outcome of this study has been the creation of my film Folk in Her Machine (2013). By exploring both the sensual qualities of lived experience, and other forms of meaning through experimental ethnographic methods, it is argued that fruitful insights have been gained into both the embodied nature of filmic representation and its performative possibilities, or in MacDougall’s words, film’s interplay “between meaning and being”.

Hydroxyapatite [Ca10(PO4)6(OH)2, HA] is used in many biomedical applications including bone grafts and joint replacements. Due to its structural and chemical similarities to human bone mineral, HA promotes growth of bone tissue directly on its surface. Substitution of other elements has shown the potential to improve the bioactivity of HA. Magnetron co-sputtering is a physical vapour deposition technique which can be used to create thin coatings with controlled levels of a substituting element. Thin films of titanium-doped hydroxyapatite (HA-Ti) have been deposited onto silicon substrates at three different compositions. With direct current (dc) power to the Ti target of 5, 10, and 15W films with compositions of 0.7, 1.7 and 2.0 at.% titanium were achieved. As-deposited films, 1.2 μm thick, were amorphous but transformed into a crystalline film after heat-treatment at 700C. Raman spectra of the PO4 band suggests the titanium does not substitute for phosphorous. X-ray diffraction revealed the c lattice parameter increases with additional titanium content. XRD traces also showed titanium may be phase separating into TiO2, a result which is supported by analysis of the Oxygen 1s XPS spectrum. In-vitro observations show good adhesion and proliferation of human osteoblast (HOB) cells on the surface of HA-Ti coatings. Electron microscopy shows many processes (i.e. filopodia) extended from cells after day one in-vitro and a confluent, multi-layer of HOB cells after day three. These finding indicate that there may be potential for HA-Ti films as a novel implant coating to improve upon the bioactivity of existing coatings.

This thesis examines the importance of the musical score in creating a film's meaning, through an analysis of the musical scores to several recent Hollywood movies. To show how film music is ideologically loaded, this thesis takes the case of the new, ultra-violent film (anti)heroine and demonstrates how the musical score works to explain, excuse or undermine her violence so that she can remain situated within the standard gender codes of Hollywood film. To do this, the theoretical section first discusses issues about the representation of femininity and the pleasures of movie violence, and then continues with a discussion of theories of musical meaning, both within and without film scores. The analysis section examines the scores to several well-known mainstream Hollywood movies, dividing the heroines into either action heroines or fatal femmes, to show firstly how these women potentially transgress gender codes, and how the music is employed - along with other filmic elements - to lessen the threat of the female character's transgression. It examines the presentation of women as mothers, victims, lesbians and jezebels - all of which roles act to frame the active heroine within some acknowledged stereotype. Finally, the thesis addresses the question of how specific this phenomenon is to Hollywood, by examining the scores to a test-case French film and its Hollywood remake. Through the analyses contained within this thesis, I show how violent Hollywood women are still subject to ideologies which position women as passive and specifically as non-violent, and that the musical score is a particularly effective means of neutralising their potential transgression of gender norms.

Over the last two centuries, a succession of childhood pursuits has been blamed for deterioration in children's health, morality, education and literacy, as well as increases in juvenile delinquency, yet there has also been a constant voice in opposition to these charges. In Britain this debate reached something of a climax in the 1930s, due to the massive growth of cinema and its huge popularity with young people. This thesis aims to explore all aspects of the controversy surrounding children's cinemagoing in the thirties, with a particular focus on the mechanisms used to try and control or contain children's viewing, together with an assessment of the extent to which these mechanisms were successful. Its main arguments are that while concerns about child viewers motivated the development of film censorship practices in Britain and elsewhere, the debate is too complex and varied to be seen as a straightforward moral panic. In addition, it argues that, despite the attempts of the BBFC and others, children were essentially the regulators of their own viewing, as they frequently subverted or circumvented the largely ineffectual mechanisms of official cinema regulation. Moreover it suggests that, in a period when school, home and even leisure tended to be strong on discipline, the cinema was colonised by children as an alternative site of recreation. Matinees in particular were the birthplace of a new and somewhat subversive children's culture, which only started to be `tamed' with the introduction of more formal children's cinema clubs towards the end of the decade. Finally, the productive nature of the debate surrounding children, cinema and censorship is explored in a cases tudy of the 1930s MGM Tarzan films, which assesses the extent to which issues relating to the child audience may have helped to shape a genre.

The first use of recorded sound in a feature film was in Don Juan (Crosland 1926). From 1933 onwards, rich film scoring and Foley effects were common in many films. In this context, Dracula (Browning 1931)1 belongs to the transitional period between silent and sound films. Dracula’s original soundtrack consists of only a few sonic elements: dialogue and incidental sound effects. Music is used only at the beginning and in the middle (one diegetic scene) of the film; there is no underscoring. The reasons for the ‘emptiness’ of the soundtrack are partly technological, partly cultural. Browning’s film remains a significant filmic event, despite its noisy original soundtrack and the absence of music. In this study Dracula’s original dialogue has been revoiced, and the film has been scored with new sound design and music, becoming part of a larger, contextual composition. This creative practice-based research explores the potential convergence of film sound and music, and the potential for additional meaning to be created by a multi-channel composition outside the dramatic trajectory of Dracula. This research also offers an analysis of how a multi-channel composition may enhance or change the way an audience reads the film. The audiovisual composition is original, but it uses an existing feature film as an element of the new art piece. Browning’s Dracula gains a new interpretation due to the semantic meaning provided by associations with major cataclysmic events of the 20th century, namely the rise of two totalitarian powers in Europe. The new soundtrack includes samples from the original that are modified, synthesised and re-worked: elements of historical speeches; quotes from Stoker’s Dracula; references to the sounds of the time period (Nazi rallies, warfare, Soviet prosecution), and the original recordings of Transylvania (similar to the geographical location and season Stoker describes in Dracula). 1 Dracula (in italics) will refer to Browning’s film (1931) throughout this paper. The soundtrack composition also includes elements of a new, specially composed Requiem, which share the same sonic and musical expression tools: music language, varying sound pitch, time stretch, granular synthesising, and vocal techniques such as singing, speech, whispering, etc.).

Syftet med denna studie har varit att, utifrån aktuell forskning, urskilja vilken didaktisk betydelse film kan ha i undervisning i ämnet historia i grundskolan. För att besvara studiens frågeställningar har en systematisk litteraturstudie genomförts i vilken vetenskaplig forskning inom området har sökts, granskats och analyserats. Resultaten visar att filmens betydelse som pedagogiskt verktyg i historie-undervisning kan delas in i tre kategorier; film som betydelse för elevers motivation, film som betydelse för elevers ökade förståelse för ämnet, samt film som betydelse för elevers kritiska tänkande. Vidare har möjligheter och svårigheter med film som pedagogiskt verktyg utifrån de tre kategorierna urskilts. Resultatet visar på olika aspekter av möjligheter och svårigheter med film, där fokus ligger på förförståelse och elevers meningsskapande. / <p>SO</p>

This thesis focuses on the 1920s Parisian avant-garde films and their artistic potential as revealed in the contemporary art of video installations. Starting with an overview of the moving image arts in the early 20th century Paris,the project deals with both the theoretical and the practical aspects of the artistic experiment. Tracing the formation of the cinematic language from contemporary static visual arts, on the one hand, and the verbal art of literature on the other, the first chapter reviews the aesthetical content of the early 20th century Parisian avant-garde (cubism, Dada and surrealism) in general and as applied to 'moving image' in particular. In addition, the artistic and critical context of 'mechanical arts', i.e. photography and cinema is analyzed, involving such issues as the categories of time and space, the visual nature of film and photography and the use of movement and the machine. The nature of video is reflected upon in close parallel with the above argument, being compared with and contrasted to that of film and photography. The second and largest chapter of the thesis is devoted to a detailed textual analysis of the 1920s Parisian experimental films. Within it, parallels are drawn between the films and a number of contemporary video installations to show the early cinematic era heritage in the 'post-cinematic' visual culture. In the last chapter the emergence and nature of new media and video installation art are considered. Multimedia installations are seen as an interactive montage in three dimensions: their 'textuality' is analyzed via the concepts of narrativity versus database, while the screen is treated as a border between the artistic space of the work and the immediate space of the viewer. furthermore, the complex nature of image in multimedia installations, including its materiality and plasticity, is considered. Such issues as the role of medium in experimental art and the importance of self-filming/documentary are reflected upon. A textual analysis of some video installations with references to the 1920s Parisian experimental films analyzed above concludes the study. An attempt to classify the installations is mader, as well as to reveal some of their typical patterns and structures. Some terminology is suggested, along with a wider perspective for future research in the field of video installation art.

This thesis explores how pirate cultures and “informal” distribution circuits operate on the ground level and integrate global media texts (mainly Hollywood films) into a small section of the local everyday society of Hanoi, Viet Nam. Situating the pirate stores and its components as active and central, this thesis will examine the physical flow of media through these store sites. In addition, by exploring the interactions between media texts, store owners and workers, customers, and the store’s design itself, this thesis will reveal how media piracy (as a form of distribution and “normal” access) influences and negotiates modernity, cultures, identities, and meanings in Hanoi and Viet Nam.

"Project Reformation" presents the process of change Amanda and Robert Bowen went through as they came to recognize Holy Spirit, the part of Trinity that was sent after the death of Jesus (John 15:26). The documentary combines various filming techniques such as observational footage, reenactments, interviews, and CGI to convey the story. This film captures the walk Robert and Amanda took as they re-examine their past, progressing through a series of supernatural encounters into a recognition of purpose and plan behind the events and experiences. While looking back on this journey, the director seeks to reveal the truth that Holy Spirit is in fact "alive and well," and walks with individuals in their daily lives by sharing how the "gifts" of miracles, healing, visions and prophecy are active even in today's age. In addition, the director desires to reveal the specific message this couple has received through this process: Not to only recognize Holy Spirit, but to reveal the "why" He is now making Himself known in these ways when many would say He has been silent for at least a generation: For reconciliation and restoration, leading to Reformation through Spiritual Healing in Family Ties (Reformation.SHIFT).
