Immersion and interaction: Creating virtual 3d worlds for stage performances
No full textThis thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.This thesis formulates an approach towards the creation of a gesture activated and body movement controlled real time virtual 3d world in a dance performance context. It investigates immersion and navigation techniques derived from modern video games and methodologies and proposes how they can be used to further involve a performer into a virtual space as well as simultaneously offer a stimulating visual spectacle for an audience. The argument presented develops through practice-based methodology and artistic production strategies in interdisciplinary and collaborative contexts.
Two choreographic performance/installations are used as cases studies to demonstrate in practice the proposed methodologies. First, the interactive dance work Suna No Onna, created in collaboration with Birringer/Danjoux and the Dap Lab, investigates the use of interactive pre-rendered animations in a real time setting and in real time by incorporating wearable sensors in the performance. Secondly, the potentials offered by the sensor technology and real time rendering engines led to the “creation scene", a key scene in the choreographic installation UKIYO (Moveable Worlds).
This thesis investigates the design, creation and interaction qualities of virtual 3d spaces by exploring the potentialities offered by a shared space, between an intelligent space and a dancer in a hybrid world. The methodology applied uses as a theoretical base the phenomenological approach of Merleau-Ponty and Mark Hansen‟s mixed reality paradigm proposing the concept of the “space schema", a system which replicates and embeds proprioception, perception and motility into the space fabric offering a world which “lives”, functions and interacts with the performer.
The outcome of the research is the generation of an interactive, non-linear, randomized 3d virtual space that collaborates with a technologically embedded performer in creating a 3d world which evolves and transforms, driven by the performer‟s intention and agency. This research contributes to the field of interactive performance art by making transparent the methodology, the instruments and the code used, in a non-technical terminology, making it accessible for both team members with less technological expertise as well as artists aspiring to engage interactive 3d media promoting further experimentation and conceptual discussions

Long-Chain Metabolites of Vitamin E: Metabolic Activation as a General Concept for Lipid-Soluble Vitamins?
No full textVitamins E, A, D and K comprise the class of lipid-soluble vitamins. For vitamins A and D, a metabolic conversion of precursors to active metabolites has already been described. During the metabolism of vitamin E, the long-chain metabolites (LCMs) 13′-hydroxychromanol (13′-OH) and 13′-carboxychromanol (13′-COOH) are formed by oxidative modification of the side-chain. The occurrence of these metabolites in human serum indicates a physiological relevance. Indeed, effects of the LCMs on lipid metabolism, apoptosis, proliferation and inflammatory actions as well as tocopherol and xenobiotic metabolism have been shown. Interestingly, there are several parallels between the actions of the LCMs of vitamin E and the active metabolites of vitamin A and D. The recent findings that the LCMs exert effects different from that of their precursors support their putative role as regulatory metabolites. Hence, it could be proposed that the mode of action of the LCMs might be mediated by a mechanism similar to vitamin A and D metabolites. If the physiological relevance and this concept of action of the LCMs can be confirmed, a general concept of activation of lipid-soluble vitamins via their metabolites might be deduced
The α-tocopherol-derived long-chain metabolite α-13'-COOH mediates endotoxin tolerance and modulates the inflammatory response via MAPK and NFκB pathways
No full textScope: The long-chain metabolites of (LCM) vitamin E are proposed as the active regulatory metabolites of vitamin E providing, with their anti-inflammatory properties, an explanatory approach for the inconsistent effects of vitamin E on inflammatory-driven diseases. We examined the modulation of cytokine expression and release from macrophages, a fundamental process in many diseases, to gain insights into the anti-inflammatory mechanisms of the alpha-tocopherol-derived LCM alpha-13'-COOH.Methods and results: Suppressed gene expression of C-C motif chemokine ligand 2 (Ccl(2)), tumor necrosis factor (Tnf), and interleukin (Il) 6 in response to lipopolysaccharides by 24 h pre-treatment with alpha-13'-COOH in RAW264.7 macrophages was revealed using quantitative reverse transcription PCR. Further, reduced secretion of IL1 beta and CCL2 was found in this setup using flow cytometry. In contrast, 1 h pre-treatment suppressed only CCL2. Consequent gene expression analysis within 24 h of alpha-13 '-COOH treatment revealed the induction of mitogen-activated protein kinases (MAPK) and nuclear factor kappa-light-chain-enhancer of activated B cells (NFxB) negative feedback regulators including the 'master regulators' dual-specificity phosphatase 1 (Dusp1/ Mkp1) and tumor necrosis factor induced protein 3 (Tnfaip3/A20). Approaches with immunoblots and chemical antagonists suggest a feedback induction via activation of extracellular-signal regulated kinase (ERK), p38 MAPK and NFxB pathways.Conclusions: CCL2 is suppressed in murine macrophages by alpha-13'-COOH and the indirect suppression of MAPK and NFxB pathways is likely a relevant process contributing to anti-inflammatory actions of alpha-13'-COOH. These results improve the understanding of the effects of alpha-13'-COOH and provide a basis for new research strategies in the context of inflammatory diseases
UKMARC AMC: Draft Rev 4.0: UK MARC format for archives and manuscripts control (UK MARC AMC)
No full textThis draft is the first attempt to establish a UK MARC specifically for Archives and Manuscripts Control since the British Library indicated that it would countenance such extensions to the national UK MARC format. In order to keep consistency with the general UK MARC format, standard UK MARC subject fields are not included in this document, since they should be taken from the latest version of the UK MARC manual. {A note of them should perhaps be included in UK MARC AMC.} {NB Text in braces is intended to be explanatory material for readers of this draft}. Certain other fields have not been included that might occasionally be used in the cataloguing of archival materials but would generally only be used for such materials in organizations which were combining archive
databases with library databases. This MARC version is intended for use with descriptions of archive or anuscript material that follow, or fit, the traditional style of cataloguing: we assume that these will normally relate
to paper or parchment originals. It is not intended for use with descriptions of other kinds of material. For these, fields may be drawn from the appropriate UK MARC document. MARC versions for use with archives in special formats should be developed, in order to complete the full range of facilities available to archivists and curators
