The Old English Prose Homily on the Phoenix

The Old English prose homily on the phoenix, which is found in two manuscripts, Cambridge, Corpus Christi College, MS 198 (eleventh century), and London, British Library, MS Cotton Vespasian D. xiv (twelfth century), is the subject of this thesis. The study addresses the homily\u27s imagery, sources, and context. Comparison of the homily with two of its closest analogues, the Old English verse Phoenix and its source, the Latin De ave phoenice attributed to Lactantius, reveals that, in spite of similarities, the homily was based upon neither; its source likely was an overtly Christian Latin text unknown to us today. In addition, there are interesting points of coincidence between the homily and the Greek Apocalypse of Baruch. Evidence suggests that the homily was intended to be preached to a general, rather than a monastic, audience, perhaps on an occasion such as St. John\u27s (Midsummer) Eve, June 23, or perhaps on various occasions, as needed. Of special interest is a list of sins found in a conclusion added only to the CCCC 198 version of the homily. The author sets out to list eight principal sins but actually names eleven, including poisoning. The selection of sins suggests the influence of penitential texts

Source code readability improvement using heuristic-based dynamic error reporting during editing

University of Technology, Sydney. Faculty of Engineering.This research considers whether dynamically reporting poor identifier-naming practices at the time when the source code is written can improve readability and hence maintainability. Poor identifier-naming practices have little effect on the production phase of the software lifecycle. However, poor identifier-naming practices can have a substantial impact during the maintenance phase of the software life cycle, particularly for the maintenance of large (i.e., 1M SLOC) computer programs. Of the nineteen identifier-naming style guidelines employed to support the research and used to identity poor identifier-naming practices, thirteen were found to be useful in improving source code readability. A questionnaire was employed to ascertain whether expert programmers accepted these guidelines; a textbook survey was used to identify the potential to transmit poor identifier-naming practices; a survey of contemporary source code was used to ascertain current identifier-naming practices; and a survey of dated source code was used to ascertain how identifier-naming practices have changed over an extended period of time. In addition, a controlled experiment was used to evaluate the effects of poor identifier-naming during a maintenance exercise and to evaluate the generation of poor identifier-naming during a production activity. A novice programmer case study and a programming team case study were executed to identify the longer term effects of dynamically reporting poor identifier-naming practices. The benefit of dynamically reporting poor identifier-naming practices was most pronounced for novice programmers with the percentage of meaningful identifier names increasing from 12% to 28%. The results for expert programmers were less pronounced with the percentage of meaningful identifier names correspondingly increasing from 53% to 60%. The identifier-naming style guidelines that proved to be the most useful to programmers required that identifier names should be composed of from two to four Natural language words or project accepted acronyms; should not be composed only of abstract words; should not contain plural words; and should conform to the project naming conventions

Collision dynamics as a tool to investigate the interactions of radicals with liquid surfaces

This thesis presents new results which are aimed at furthering the understanding of collision dynamics at gas-liquid interfaces. These experiments included the use of open shell radicals such as OH and both ground sate O(3P) and excited state O(1D) oxygen. The liquids used included an un-reactive standard per fluoropolyether, Krytox 1506 but were mostly focussed on the potentially reactive saturated and unsaturated counterparts squalane and squalene. The products of scattering from these liquid surfaces were detected by laser induced fluorescence (LIF). The radicals were all used as a “chemical probe” of the liquid surface. Using information on the translational and internal energy distributions of the scattered species the structure and reactivity of each liquid surface could be investigated. Important findings included the first measurements of the reaction of O(1D) with a liquid hydrocarbon surface. The data collected were analysed to provide the first comparisons of O(1D) scattering from a liquid with previous gas phase measurements. Relevant mechanisms identified for these comparable gas-phase reactions were assigned as far as possible to the new results. For the first time, the interactions of rotationally excited OH radicals with liquid surfaces were investigated. Liquid surfaces of atmospheric relevance were studied. This work was compared to that completed previously using a rotationally near-thermal source of OH radicals. Important scattering mechanisms were identified and assigned to the results collected. A possible loss mechanism for OH radicals interacting with unsaturated species was identified. The first comparison of the interfacial reaction of O(3P), with squalane and its unsaturated counterpart, squalene was conducted. Scattering mechanisms were identified and characterised where possible. Differences in scattering dynamics were observed with the unsaturated liquid surface, which were attributed to differences in the chemical nature of the bonds present in the liquid. Where possible, all results were related to reactions which occur in the atmosphere

Increasing Production Efficiency Of an Extension Radio Program

Restrictions on time and money available for The Virginia Gardener radio program forced a re-evaluation of standard weekly or monthly production procedures. By changing to an annual system and using existing resources more efficiently, the program has become easier to produce and fits into station schedules more readily. The use of many guests has made it more interesting and diverse, and it is now widely used by Extension agents as well as radio stations. It is sent to 58 stations, which broadcast it an average of twice each week

Progress of the edible-oil flax program at the Crop Development Centre

Non-Peer ReviewedAn edible-oil flax crop will provide Saskatchewan farmers with an additional cropping option and help to extend crop rotations. Australian researchers have recently produced an edible-oil flax but this genetic material is not available to public institutions. Consequently, we were forced to produce our own mutant flax lines by treating the variety McGregor with the mutagen EMS (ethyl methanesulphonate). The objective of our research was to induce mutations that would lower the linolenic acid content of flax seed. To date we have isolated three mutant lines with lowered linolenic acid levels. Each of these lines has elevated levels of other fatty acids. Line E67 has increased concentrations of palmitic acid, line E1747 greatly increased levels of linoleic acid and line E1929 has increased oleic acid levels. Flaxseed, as produced today, is processed into linseed oil. The drying properties of linseed oil make it useful as a component of oil-based paints and of linoleum. However, these same drying properties cause linseed oil to oxidize and turn rancid, making it unsuitable for human consumption. The most prevalent fatty acid in linseed oil is linolenic acid and this fatty acid imparts most of the drying quality to the oil. Green (1986) described the development in flax (Linum usitatissimum L.) of a genotype whose seed contained less than 2% linolenic acid. The low linolenic acid character is controlled by two recessive genes that were produced by EMS (ethyl methanesulphonate) mutagenesis in the Australian cultivar Glenelg. These very low levels of linolenic acid have resulted in flax being considered for edible-oil purposes. The discovery of these fatty acid mutants brought the hope that edible oil flax cultivars could be developed for Saskatchewan. However, we were unable to obtain low linolenic acid lines from the Australians. We, therefore, began our own mutagenesis program with the hope of duplicating the Australian results

CREATING AN INNOVATION OPPORTUNITY SPACE FOR BROADACRE SMART FARMING: A CASE STUDY OF AUTONOMOUS FARM EQUIPMENT

Advances in digital technologies are transforming the agriculture and agri-food system. The technological changes are represented in many forms, ranging from software-based prescriptions for optimal rate application of farm inputs, advanced imagery of fields and plants collected by sensors, satellites and drones, to new forms of human-to-machine interactions and machine learning This thesis is a case study of one type of a smart farming innovation, a field robot., originating from a small-to-medium sized enterprise (SME) that designs and manufacturers machinery used in broadacre, conservation tillage farming. The innovation, known as DOT™, is an entrepreneur’s response to problems in the agriculture industry, and a solution to a critical constraint of labour shortages in the sector. By gathering qualitative data through interviews, news items and academic publications, observing the farming community’s engagement with digital technology innovation at farm show, and applying the Innovation Opportunity Space (IOS) analytical framework, this study identified that an autonomous DOT™ offers a solution for farming problems. Other firms are incorporating the DOT™ technology into their manufacturing operations through licensing agreements and early farmer adoption is positive. The process of innovation was based on synthesis of tacit knowledge (experience-based knowledge of farming and agribusiness) and codified knowledge (drawing on computer programing), while public policy facilitated the hiring of trained university students who remain with the SME as advocates for smart farming. There remain some gaps: public policy for safe deployment of smart farming innovation is lagging behind invention and commercialization; new business models for manufacture and commercialization of high-tech equipment are just emerging and data ownership and control remains unresolved; and evidence of the value of smart farming technologies to farmers and the larger social system remains scant

Similar Inflammatory Responses following Sprint Interval Training Performed in Hypoxia and Normoxia

Sprint interval training (SIT) is an efficient intervention capable of improving aerobic capacity and exercise performance. This experiment aimed to determine differences in training adaptations and the inflammatory responses following 2 weeks of SIT (30 s maximal work, 4 min recovery; 4–7 repetitions) performed in normoxia or hypoxia. Forty-two untrained participants [(mean ± SD), age 21 ±1 years, body mass 72.1 ±11.4 kg, and height 173 ±10 cm] were equally and randomly assigned to one of three groups; control (CONT; no training, n = 14), normoxic (NORM; SIT in FiO2: 0.21, n = 14), and normobaric hypoxic (HYP; SIT in FiO2: 0.15, n = 14). Participants completed a V ˙ O 2peak V˙O2peak test, a time to exhaustion (TTE) trial (power = 80% V ˙ O 2peak V˙O2peak) and had hematological [hemoglobin (Hb), haematocrit (Hct)] and inflammatory markers [interleukin-6 (IL-6), tumor necrosis factor-α (TNFα)] measured in a resting state, pre and post SIT. V ˙ O 2peak V˙O2peak (mL.kg−1.min−1) improved in HYP (+11.9%) and NORM (+9.8%), but not CON (+0.9%). Similarly TTE improved in HYP (+32.2%) and NORM (+33.0%), but not CON (+3.4%) whilst the power at the anaerobic threshold (AT; W.kg−1) also improved in HYP (+13.3%) and NORM (+8.0%), but not CON (–0.3%). AT (mL.kg−1.min−1) improved in HYP (+9.5%), but not NORM (+5%) or CON (–0.3%). No between group change occurred in 30 s sprint performance or Hb and Hct. IL-6 increased in HYP (+17.4%) and NORM (+20.1%), but not CON (+1.2%), respectively. TNF-α increased in HYP (+10.8%) NORM (+12.9%) and CON (+3.4%). SIT in HYP and NORM increased V ˙ O 2peak V˙O2peak, power at AT and TTE performance in untrained individuals, improvements in AT occurred only when SIT was performed in HYP. Increases in IL-6 and TNFα reflect a training induced inflammatory response to SIT; hypoxic conditions do not exacerbate this
