description: In contemporary rural healthcare settings, the principal challenge in diagnosing brain images is the scarcity of available data, given that most of the existing deep learning models demand extensive training data to optimize their performance, necessitating centralized processing methods that potentially compromise data privacy. This paper proposes a novel framework tailored for brain tissue segmentation in rural healthcare facilities. The framework employs a deep reinforcement learning (DRL) environment in tandem with a refinement model (RM) deployed locally at rural healthcare sites. The proposed DRL model has a reduced parameter count and practicality for implementation across distributed rural sites. To uphold data privacy and enhance model generalization without transgressing privacy constraints, we employ federated learning (FL) for cooperative model training. We demonstrate the efficacy of our approach by training the network with a limited data set and observing a substantial performance enhancement, mitigating inaccuracies and irregularities in segmentation across diverse sites. Remarkably, the DRL model attains an accuracy of up to 80%, surpassing the capabilities of conventional convolutional neural networks when confronted with data insufficiency. Incorporating our RM results in an additional accuracy improvement of at least 10%, while FL contributes to a further accuracy enhancement of up to 5%. Collectively, the framework achieves an average 92% accuracy rate within rural healthcare settings characterized by data constraints.

description: In the task of aspect sentiment quad prediction (ASQP), generative methods for predicting sentiment quads have shown promising results. However, they still suffer from imprecise predictions and limited interpretability, caused by data scarcity and inadequate modeling of the quadruplet composition process. In this paper, we propose Self-Consistent Reasoning-based Aspect-sentiment quadruple Prediction (SCRAP), optimizing its model to generate reasonings and the corresponding sentiment quadruplets in sequence. SCRAP adopts the Extract-Then-Assign reasoning strategy, which closely mimics human cognition. In the end, SCRAP significantly improves the model's ability to handle complex reasoning tasks and correctly predict quadruplets through consistency voting, resulting in enhanced interpretability and accuracy in ASQP.

description: We study the $K^{+}d$ scattering at low energies using the optical potential. Our optical potential consists of the first-order and second-order terms. The total, integrated elastic and elastic differential cross sections at incident kaon momenta below 800 MeV/c are calculated using our optical potential. We found that our results are consistent with the Faddeev calculation as well as the data and especially the second-order optical potential is essential to reproduce them at low energies. We also discuss the multiple scattering effects in this process.

description: This study investigates the transfer of soil to shoe soles when a perpetrator disposes of a corpse in a forested area. During such an action soil is transferred to the shoe soles, but it is unknown which point(s) along the transect transfers the most soil to the shoe soles. This information is needed for taking a soil sample at a crime scene to make a comparison between the crime scene and the shoes which are thought to be linked with the crime. Previous research has mainly been focused on case studies while experimental data is lacking. This study will therefore focus on collecting experimental data by simulating the dumping of a corpse at five different locations. The pollen underneath the boots and the pollen along the transect are compared with each other to see where the highest similarity between the boots and the transect could be found. The similarity indicates where the transfer of soil to the shoe soles is highest and thus where a soil sample during investigation of a crime scene should be taken. The point with the highest similarity to the boots varies between the locations. This indicates that the transfer of soil to shoe soles does not happen at a set point along the transect, but depends on different factors, like moisture, ground coverage and compacted soil. The locations Heemskerk, IJsselstein and Bosrand showed the highest similarity with the points which were the muddiest, had the lowest amount of compacted soil or had limited ground coverage. The locations Schaapsallee and Utrechtse Heuvelrug showed the highest similarity with the average of the total transect because the moisture, ground coverage and compacted soil were comparable throughout the complete transect. In addition, the total transect showed a high similarity with the boots at every location. However, when the amounts of moisture, ground coverage and compacted soil varied along a transect, there was always one point along that transect with a higher similarity to the boots than they had with the total transect. In conclusions, the point(s) were soil is transferred to shoes are the muddiest part, the points with limited ground coverage or the least compacted soil. However, if the whole transect shows similarities in these factors, it is best to take multiple samples along the transect from which the average could be used.
title: Mineralogy and Petrology of Lava Flows (Tertiary-Quaternary) In Southeastern Idaho and at Black Mountain, Rich County, Utah
Creators: name: Puchy, Barbara J.
Publisher: name: Utah State University
Year: 1981

description: Lava flows of Tertiary-Quaternary age occur in Enoch Valley, Upper Valley, and Slug Valley in southeastern Idaho. The basalts in Upper Valley and Enoch Valley contain olivine (Fo69 to Fo37), plagioclase (An62 to An39), augite and Fe-Ti oxides. The lava in Slug Valley lacks plagioclase, but contains sanidine (Or70 to Or56) with a trace of biotite and amphibole, and thus, has been termed alkali trachyte.
Black Mountain, on the eastern side of Bear Lake, northeastern Utah, is capped by basalt. Minerals present include olivine (Fo83 to Fo72), plagioclase (An71 to An53 J, augite, and magnetite.
Chemically, the basalt of Enoch Valley is comparable to olivine tholeiite of the Snake River Plain, as it contains olivine and hypersthene in the norm. The basalt of Upper Valley contains a greater amount of Si02 and K2O and less MgO than tholeiite of the Snake River Plain. This basalt contains normative quartz and hypersthene and is classified as tholeiite. The presence of nepheline and olivine in the norm of the basalt from Black Mountain indicates that it is an alkali-olivine basalt. The lava from Slug Valley contains high K and Mg, moderate Si, and low Al and Na. It is similar to lamproites of orenditic affinity.
The temperatures of crystallization calculated from co-existing olivine and pyroxene, range from 1,015 degrees C to 996 degrees C for the valley basalts, and range from 1,021 degrees C to 1,002 degrees C for the alkali trachyte. The temperature calculated for the basalt sample from Black Mountain is 1,015 degrees C. The temperatures estimated using coexisting magnetite and ilmenite range from 1,021 degrees C to 978 degrees C for the valley basalts.
The proposed origin of the Enoch Valley basalt is that it is a direct product of partial melting of a mantle of pyrolite composition. Fractionation, during ascent of the magma, could possibly have produced the Upper Valley lava. The basalt on Black Mountain was possibly derived as the result of partial melting of a pyrolitic mantle as well, but due to differences in mineralogy and normative constituents, it seems to be unrelated to the valley basalts. The origin of the Slug Valley alkali trachyte is uncertain. This lava may have been generated from a mica peridotite mantle and is possibly related to the Leucite Hills lava in Wyoming.

description: In this paper we study the BPS state counting in the geometry of local obstructed curve with normal bundle O+O(-2). We find that the BPS states have a framed quiver description. Using this quiver description along with the Seiberg duality and the localization techniques, we can compute the BPS state indices in different chambers dictated by stability parameter assignments. This provides a well-defined method to compute the generalized Donaldson-Thomas invariants. This method can be generalized to other affine ADE quiver theories.

Soil disturbance by native mammals and the germination and establishment of plant species
Creators: name: Pyrke, A
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis investigates disturbances created by the digging of small native mammals and their role in the germination and establishment of native plant species in eastern Tasmania, with a particular focus on species considered to be rare or threatened. At least 15 rare and endangered plant species live in habitats where digging appears to be common. Soil disturbances, which are created by bettongs, bandicoots and echidnas, can be prolific, particularly on soils of lower fertility. Turnover rates of up to 2.9% of the ground surface per annum were recorded. Diggings by bettongs, and to a lesser degree by bandicoots, are spatially associated with trees in dry sclerophyll and grassy woodlands and forests. The understorey varies in species composition depending on the degree of tree influence, so not all understorey species are close (at the scale of several metres) to where digging disturbances are most abundant. Digging creates small patches of bare ground which, on sandy soils, can be a harsh environment with low nutrient and moisture availability. However, diggings provide better conditions for the germination of many species, particularly those with small seeds and perhaps also some species which have hard-seeded dormancy. This latter effect may be a result of the considerable soil heating imposed by direct solar radiation on bare soil. Several species had higher densities of seedlings on animal diggings, although mortality rates were generally very high on both digging disturbances and undisturbed areas. Seedlings died faster, at the same rate, or slower on diggings compared with undisturbed areas, depending on the species and the circumstances. Simulated animal disturbances proved to be effective in stimulating germination, and more substantial survival of seedlings was recorded in these experiments than on natural diggings. Many plant species in this study have seed stored in the soil at depth. Digging probably brings buried seed to the surface which would otherwise not germinate. Rare or threatened species which were found to benefit from either natural diggings or simulated disturbances included Lepidium hyssopifolium, L. peudotasman icum, L1siopetalum micranthum, Vittadinia muelleri and Velleia paradoxa. No rare species appeared to be completely dependent on animal digging for a regeneration niche, but the potential exists to use mechanical disturbance as a management tool for some species. The density of an exotic annual grass, Briza maxima, was considerably less on larger digging mounds compared with undisturbed areas, even three years after the creation of the mounds. There was evidence that native seedlings were experiencing less competition from B. maxima on these mounds and perhaps have a better opportunity for establishment.

title: A Critical Appraisal of Methods of Sucrose Analysis in Sugar Beets
Creators: name: Lebaron, Homer M.
Publisher: name: Utah State University
Year: 1958

description: Although the parent of the present sugar beet was probably known and used before the building of the pyramid of Cheops (22), it was as recent as 210 years ago that Marggraf obtained the first crystalized sucrose from the root. It was 40 years later before Achard claimed its potentialities as an efficient industry. The product rapidly passed from the status of a luxury to a vital necessity, until today sugar beet production receives some protection or preference in every country where sugar beets are grown.
Throughout its 174-year history it has probably been beset with a greater variety of problem and more failures than any other industry before or since. One of the greatest problems has been the actual means of sucrose extraction and determination.
The determination of sucrose in sugar beets is the most important function in a beet sugar factory laboratory (3). This value is necessary as the basis for calculations of sugar yields and losses, for fixing the value of beets in factories where these are bought on the basis of their sugar content and for other purposes. Sugar content determinations are also for vital importance to the plant breeder, soil scientist, plant physiologist, and other researchers concerned with sugar beet analysis.
Values of such importance should be determined by methods of corresponding accuracy. However, in 1927 Stanek and Vondrak (3) stated that there is no routine method as yet which permits the determination of the sugar in the beet to within an accuracy of 0.1 per cent. It is doubtful that the fundamental accuracy of the saccharimetry methods has improved much since this time.
Numerous methods of sucrose analysis are used and are being recommended for use both in sugar beet factory and research laboratories. Although most methods now used are based on the principle of aqueous digestion and single polarimetry, there are wide variations in actual procedures. The available literature is deficient in adequate comparative studies into this problem. It would be of considerable value to researchers in sugar beet production and analysis to know the relative accuracy and precision of these methods and the effects of the several variables now prevalent.

description: In this work, it is suggested that the extremum complexity distribution of a high dimensional dynamical system can be interpreted as a piecewise uniform distribution in the phase space of its accessible states. When these distributions are expressed as one--particle distribution functions, this leads to piecewise exponential functions. It seems plausible to use these distributions in some systems out of equilibrium, thus greatly simplifying their description. In particular, here we study an isolated ideal monodimensional gas far from equilibrium that presents an energy distribution formed by two non--overlapping Gaussian distribution functions. This is demonstrated by numerical simulations. Also, some previous laboratory experiments with granular systems seem to display this kind of distributions.

I talked to my tree and my tree talked back: radical environmentalists and their relationships with nature
Creators: name: Cianchi, JP
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis is about the relationship between radical environmental activists and nature. It investigates whether, for forest and whaling activists, nature is experienced as an active, as opposed to passive, participant in the construction and shaping of their identity and activism. Two research questions guide the investigation: what are radical environmental activists' perspectives and lived experiences of nature, and what identity and meaning-making processes are involved in the relational dynamics between these activists and the nature they are defending? The concepts 'nature', 'self-identity' and 'more-than-human agency' are developed into an analytical framework to support the investigation. A phenomenological perspective guides the inquiry's focus on the research participants' lived experiences of defending nature, their changing self-identities and the ways they construct meaning about their lifeworlds. Forest activists engaged in direct action campaigns designed to prevent clear-felling of old growth forests in Tasmania, and Sea Shepherd Conservation Society activists undertaking campaigns in the Southern Ocean to protect whales, participated in in depth qualitative interviews. A thematic analysis was employed that aims to uncover the phenomenological themes, or experiential elements, of the participants' experiences. The inquiry's findings contribute to environmentalism scholarship and the study of nature-human relationships. They also demonstrate the need to appreciate the role of nature as an active contributor to activist self-identity and culture.
title: The Role of Homeostatic Imbalance in the Reported Immunomodulation of T-2 Toxin
Creators: name: Taylor, Michael Jay
Publisher: name: Utah State University
Year: 1988

description: T-2 toxin (T-2), produced by the genus Fusarium, is a cytotoxic trichothecene mycotoxin, a feed contaminant, and has been shown to be immunomodulatory. It is suspected that T-2-associated immunomodulation is mediated partly through the hypothalamic-pituitary-adrenal axis. The presence of endotoxin, a bacterial product capable of activating the hypothalamic-pituitary-adrenal axis as well as the levels of several hormones, also associated with activation of the hypothalamic-pituitary-adrenal axis, were determined in both vehicle- and toxin-treated animals. Endotoxemia was evident twenty-four hours after a single oral exposure to T-2. Blood levels of adrenocorticotropic hormone and corticosterone, parameters of the stress response, also increased twenty-four hours after T-2 exposure. Hypothalamic norepinephrine and serum corticosterone levels increased in a dose-related manner after two weeks of T-2 exposure. An increased corticosteroid level was associated with thymic involution leading potentially to decreased T-dependent antibody response, a known effect of T-2. The effects of exposure to T-2 on the development of both T-dependent and T-independent antibody response were determined in nonoperated, sham-operated and adrenalectomized mice. T-2 decreased the antibody response to a T-dependent antigen and increased a T-independent response. The effects of T-2 were partially nullified by adrenalectomy. These results provide a further confirmation of the postulate that the hypothalamic-pituitary-adrenal axis plays an important role in T-2 toxin-immunomodulation. In vitro studies were undertaken to investigate the direct effects of T-2 on various populations of lymphatic cells. Exposure to T-2 after twenty-four hours caused an increase in the uptake of 3H-thymidine by mouse splenic cells. Pokeweed mitogen stimulation also increased in this system; the response to lipopolysaccharide increased to a lesser extent. However, T-cell responses to phytohaemagglutinin and concanavalin A (Con A) decreased. Thymic cells were also sensitive to T-2. The possibility of pharmacological activity of T-2 with thymocytes was investigated. Both specific and nonspecific cell associations were observed. The association of T-2 with thymocytes was altered in the presence of dexamethasone, a synthetic corticosteroid. T-2 was shown to have both indirect as well as direct activities on the immune system. Endocrine dysfunction resulting from chronic stress and possible pharmacologic activity of T-2 provide the impetus for further investigations.

Mandatory release in Canada : a cost and manpower analysis of mandatory release in Canada
Creators: name: Devine, S. Antoinette
Publisher: name: University of British Columbia
Year: 2011

description: The field of corrections is anticipating a change in the present system of releasing inmates from prison. This new development has been described in a variety of terms. However, for purposes of this study, it will be referred to as "The Mandatory Release System". This concept is defined as " a system whereby those inmates who are not granted regular parole, have the opportunity to accept release, after serving three-quarters of their sentence, provided they accept supervision for the statutory remission period of their sentence." The most logical structure to accommodate and implement this change is the National Parole Board. Since there is presently a general lack of knowledge in this area, considerable research is required to identify the implications of such a proposal. The authors have chosen to focus upon the cost and manpower requirements essential in providing a supervision program. The study is based on the premise that supervision is a major factor in the rehabilitation of the offender. Furthermore, it offers additional protection to the community by the reduction of recidivism. By utilizing present data and knowledge available, an estimate was made of the number of inmates who will be affected by this change. These calculations were used to determine the manpower and cost required for differential models of supervision based on the number of hours spent with the releasee. Recommendations arising out of the findings of the study were many and varied. The principle recommendation being in order to make better use of similar programs in existence a more effective gathering and co-ordination of statistical data is necessary. This study intends to fulfil a dual purpose: that of fulfilling the requirements of the Master of Social Work thesis as well as intending to provide useful information to those government administrators who will be concerned with the implementation of this new legislation.
title: The Effect of Chemical Competition on Thermodynamics of Bacterial Adsorption
Creators: name: Khairnar, Deorao R.
Publisher: name: Utah State University
Year: 1970

description: The objective of this investigation was to study the effect of chemical competition on thermodynamics of bacterial adsorption. This was done using an experimental system consisting of Mendon silt loam soil as the adsorbent, Staphylococcus aureus as a common adsorbate and sodium chloride (NaCl), sodium lauryl sulfate (SLS), and peptone as competitive adsorbates.
The bacterial adsorption on soil both with and without chemical competition followed Langmuir type isotherms. From the equilibrium data, thermodynamic functions such as free energy, ΔF°, enthalpy, ΔH°, and entropy, ΔS°, were calculated. Observed positive ΔH° values indicated that the bacterial uptake in both noncompetitive and competitive environments is endothermic. Bacteria and soil both have a negative charge. A positive ΔH° value is attributed to the repulsion between the bacteria and soil particles. For a non-competitive system, the observed ΔH° value was 8.50 kcal-mole-1. Relatively higher ΔH° values were obtained in the presence of peptone and NaCl. These values were 24.0 kcal-mole-1 and 23.0 kcal-mole-1 for peptone and NaCl respectively, suggesting that the bacterial uptake is much more endothermic in the presence of these chemicals. The lower ΔH° value (3.72 kcal-mole-1) observed in the presence of SLS indicated that bacterial adsorption is relatively less endothermic in the presence of such a chemical.
In all the sorbent-sorbate systems studied, observed ΔS° values were positive indicating that the bacteria are more disordered in the adsorbed phase than they are in the solution phase. Observed ΔF° values for all the adsorption systems were negative, indicating that the bacterial adsorption in both competitive and noncompetitive environments is spontaneous.
title: Moisture and Temperature Effects on the Transformations of Nitrogen from Applied Ammonium Sulfate in a Calcareous Soil
Creators: name: Justice, John Keith
Publisher: name: Utah State University
Year: 1961

description: nitrogen has commonly been a deficient element in the cultivated soils of the world since the beginning of agriculture. The general acceptance of the practice of using manures as a means of increasing plant growth, as shown by the records of ancient civilizations, attest to this fact. Since the time of von Liebig there has been an increasing awareness of the importance of this deficiency in soils. As a result of a better understanding of the problem and the increasing availability of commercial forms of nitrogen, a rapid increase in the use of nitrogen fertilizers has taken place in the last few decades.
this increasing use of commercial forms of nitrogen is accompanied by the need for more information concerning the proper use of these materials in order to accomplish the greatest benefit. For example, with the advent of increasing use of ammonium fertilizer to improve soil productivity, there has arisen a possibility of lengthening the period from the date of the fertilizer application to the time of utilization by the crop. this advanced application, especially in the fall of the year, has many advantages and is widely advocated. The following questions need to be answered in connection with efficiency of such a practice: Will the ammonium form of nitrogen remain unoxidized in the soil over the winter months? Could it be only partially oxidized and result in an accumulation of nitrites that may cause toxicity or be lost from the soil in gaseous forms such as nitrous oxide? What are the chance for significant losses by volatilization before it is oxidized? How does the amount of moisture and the prevailing temperature affect these transformations?
The study reported here is an endeavor to contribute to more complete answers to some of these questions. Although much research has been conducted relating to the effects of moisture or temperature on nitrogen transformations in the soil, more information is needed covering greater variations in the moisture and temperature levels along with the interactions of these. Accordingly, experiments were conducted under carefully controlled conditions to measure the changes occurring in the inorganic soil nitrogen from an applied ammonium source, at various moisture and temperature levels.

description: The spectral signatures of asymmetry in Type Ia Supernova (SN Ia) explosions are investigated, using a sample of late-time nebular spectra. First, a kinematical model is constructed for SN Ia 2003hv, which can account for the main features in its optical, Near-Infrared (NIR), and Mid-Infrared (Mid-IR) late-time spectra. It is found that an asymmetric off-center model can explain the observed characteristics of SN 2003hv. This model includes a relatively high density, Fe-rich region which displays a large velocity off-set, and a relatively low density, extended 56Ni-rich region which is more spherically distributed. The high density region consists of the inner stable Fe-Ni region and outer 56Ni-rich region. Such a distribution may be the result of a delayed-detonation explosion, in which the first deflagration produces the global asymmetry in the innermost ejecta, while the subsequent detonation can lead to the bulk spherical symmetry. This configuration, if viewed from the direction of the off-set, can consistently explain the blueshift in some of the emission lines and virtually no observed shift in other lines in SN 2003hv. For this model, we then explore the effects of different viewing angles and the implications for SNe Ia in general. The model predicts that a variation of the central wavelength, depending on the viewing angle, should be seen in some lines (e.g., [Ni II]7378), while the strongest lines (e.g., [Fe III] blend at 4700A) will not show this effect. By examining optical nebular spectra of 12 SNe Ia, we have found that such a variation indeed exists. We suggest that the global asymmetry in the innermost ejecta, as likely imprint of the deflagration flame propagation, is a generic feature of SNe Ia (abridged).

description: Objective— Patients with in-hospital stroke often have contraindications to intravenous alteplase(1), (2).Mechanical thrombectomy is a treatment option, even for patients otherwise ineligible for intravenous alteplase. Wecompare outcomes between mechanical thrombectomy performed in patients with strokes that occurred in-hospitalversus community-onset strokes.Methods— This is an Institutional Review Board-approved, retrospective cross-sectional study analyzing patientswho underwent thrombectomy for acute ischemic stroke with large vessel occlusion between January 2012 andNovember 2017 at Tampa General Hospital. We performed logistic regression analysis to compare the outcomesbetween patients with in-hospital stroke and community-onset stroke after adjusting for potential confounders.Results— A total of 334 patients received mechanical thrombectomy for acute ischemic stroke: 13.2% were in-hos-pital and 86.8% were community-onset. Patients who presented with strokes that occurred in-hospital were signifi-cantly younger (mean age 60.7 vs. 70.4 years; p<0.001). In-hospital stroke treated with mechanical thrombectomyhad lower pretreatment with intravenous alteplase (14% vs. 34%; p=0.006). Patients with in-hospital stroke had asignificantly shorter time interval between symptom recognition and groin puncture (p=0.039). Also, in-hospitalstroke patients had significantly higher rates of favorable outcomes at discharge as measured by the modified Rankinscale 0–3 (52% vs. 32%; p=0.009) and continued to have favorable outcomes (adjusted odds ratios =4.832; 95% Cl,(1.207-19.348); P=0.026) after adjustment for age and National Institute of Health Stroke Scale which were felt tobe potential confounders.Conclusions— Compared with patients with community-onset stroke, patients with in-hospital stroke whounderwent thrombectomy had higher rates of favorable outcomes at discharge.

description: The objective in wheat hybridization primarily is to obtain new varieties which are of a greater agronomic value than existing varieties. Frequently, however, crosses which obviously will not produce superior commercial types are made and studied in order to obtain genetic information which may be useful to the breeder. This latter phase of breeding, i.e., the accumulation of genetic information, provides the basis for this study.

description: Naturally ventilated livestock buildings (NVLB) represent one of the most significant sources of ammonia emissions. However, even the dispersion of passive gas in an NVLB is still not well understood. In this paper, we present a detailed investigation of passive pollutant dispersion in a model of a cattle barn using the wind tunnel experiment method. We simulated the pollution of the barn by a ground-level planar source. We used the time-resolved particle image velocimetry (TR-PIV) and the fast flame ionisation detector (FFID) to study the flow and dispersion processes at high spatial and temporal resolution. We employed the Proper Orthogonal Decomposition (POD) and Oscillating Patterns Decomposition (OPD) methods to detect the coherent structures of the flow. The results show that the type of atmospheric boundary layer (ABL) and sidewall opening height have a significant impact on the pollutant dispersion in the barn, while the presence of animals and doors openings are insignificant under conditions of winds perpendicular to the sidewall openings. We found that the dynamic coherent structures, developed by the Kelvin-Helmholtz instability, contribute to the pollutant transport in the barn. We demonstrate that in any of the studied cases the pollutant was not well mixed within the barn and that a significant underestimation (up to by a factor 3) of the barn ventilation might be obtained using, e.g. tracer gas method. © 2020 The Authors
Viewing the 'Lower Class' through Today Tonight: An analysis of Housos re-representation
Creators: name: Eiszele, JS
Publisher: name: University Of Tasmania
Year: 2023

description: There is an extensive body of academic research into media representation highlighting and analysing the nature of racial or gendered representations. Comparatively there has been little recent research done into depictions of the 'lower class'. This study aims to build upon the work on this disadvantaged group by focusing on Australian current affairs programme Today Tonight. In doing so, this thesis will be building upon the limited amount of work that has been done on the Australian media in regard to class representation. As there has been little research specifically into Today Tonight's approach to 'lower-class' people it also helps fill a notable gap. It is imperative to look at the link between representations of this group alongside the hegemony of the mainstream media. The utilisation of Antoni Gramsci's theory of hegemony is used in this thesis to attempt to offer a conceptual perspective of media representation concerning the 'lower class'. This research deliberately chooses to apply the term, 'lower class', as opposed to 'working class' as it defines both the self and external representations of this group. The thesis argues that the group is presented as unsocial, threatening and consequently deviant by Today Tonight. As a case study, this thesis uses the programme's coverage of the filming of the movie Housos vs Authority which highlights how the programme draws upon the representations on offer in the satirical show to contribute to a common sense understanding of the group. To add substance to an analysis of this re-representation, the thesis highlights a typical report on the real-life 'lower class' by Today Tonight as well as an episode of Housos to compare and (where possible) contrast the approaches taken by these texts with the Housos movie report. The research identifies a dichotomy between representations of this group with that of the 'middle class' in the programme and that this ultimately furthers a negative depiction of the lower socio-economic group by emphasising their anti-social behaviours in contrast to the middle class's more favourable representation. The thesis argues that the media contributes to inequality by treating a disadvantaged group unfavourably, effectively disparaging people who are in abject or 'lower' situations chiefly due to processes out of their control.
title: A Study of the Factors Influencing the Synthesis of Tobacco Mosaic Viral RNA in a Partially Purified Synthesizing System
Creators: name: Fok, Agnes P.
Publisher: name: Utah State University
Year: 1966

description: Research on biosynthesis of tobacco mosaic virus (TMV) ribonucleic acid (RNA) in vitro has been reported by Cochran, et al; Karasek and Schramm; Kim and Wildman; Cornuet and Astier; and Tongur and Baland in. It has been postulated that the replication of a number of viruses containing single-stranded RNA is accompanied by the formation of a virus-specific double-stranded helical RNA, the replicative form. This has been demonstrated both for animal and bacterial viruses including MS2. The double helical structure of purified replicative form of MS2 was established by X-ray diffraction studies. One of the strands was shown to be a viral RNA strand of the parental type ("plus" strand), the other being complementary to it ("minus" strand). Studies on Escherichia coli infected with RNA phages suggest that a structure containing both a "plus 11 and a "minus " strand is an obligatory intermediate in viral reproduction.
Conduction bands in classical periodic potentials

description: The energy of a quantum particle cannot be determined exactly unless there is an infinite amount of time in which to perform the measurement. This paper considers the possibility that $ΔE$, the uncertainty in the energy, may be complex. To understand the effect of a particle having a complex energy, the behavior of a classical particle in a one-dimensional periodic potential $V(x)=-\cos(x)$ is studied. On the basis of detailed numerical simulations it is shown that if the energy of such a particle is allowed to be complex, the classical motion of the particle can exhibit two qualitatively different behaviors: (i) The particle may hop from classically-allowed site to nearest-neighbor classically-allowed site in the potential, behaving as if it were a quantum particle in an energy gap and undergoing repeated tunneling processes, or (ii) the particle may behave as a quantum particle in a conduction band and drift at a constant average velocity through the potential as if it were undergoing resonant tunneling. The classical conduction bands for this potential are determined numerically with high precision.

description: Relations between bulk mass parameters for fermions propagating in higher dimensions are studied in analogy with the empirical mass relation for charged leptons. Masses of three generation of four-dimensional charged leptons are achieved from the bulk mass parameters of the same-order values. We find that the observed pattern of charged lepton mass spectrum is accommodated approximately in a set of simple relations for bulk and physical masses.

description: We study how to protect quantum information in quantum systems subjected to local dissipation. We show that combining the use of three-level systems, environment monitoring, and local feedback can fully and deterministically protect any available quantum information, including entanglement initially shared by different parties. These results can represent a gain in resources and/or distances in quantum communication protocols such as quantum repeaters and teleportation as well as time for quantum memories. Finally, we show that monitoring local environments physically implements the optimum singlet conversion protocol, essential for classical entanglement percolation.
Is J 133658.3-295105 a Radio Source at z >= 1.0 or at the Distance of M 83?

description: We present Gemini optical imaging and spectroscopy of the radio source J 133658.3-295105. This source has been suggested to be the core of an FR II radio source with two detected lobes. J 133658.3-295105 and its lobes are aligned with the optical nucleus of M 83 and with three other radio sources at the M 83 bulge outer region. These radio sources are neither supernova remnants nor H II regions. This curious configuration prompted us to try to determine the distance to J 133658.3-295105. We detected H_alpha emission redshifted by ~ 130 km s^-1 with respect to an M 83 H II region 2.5" east-southeast of the radio source. We do not detect other redshifted emission lines of an optical counterpart down to m_i = 22.2 +/- 0.8. Two different scenarios are proposed: the radio source is at z >= 2.5, a much larger distance than the previously proposed lower limit z >= 1.0, or the object was ejected by a gravitational recoil event from the M 83 nucleus. This nucleus is undergoing a strong dynamical evolution, judging from previous three-dimensional spectroscopy.
