description: When generating electricity at thermal power plants, the main working fluid is water vapor. To obtain water steam with the required parameters, boiler units are designed. The purpose of this final qualifying work is to design the boiler unit E-540-13.7-555. The result of the work is a designed boiler unit, which can be included in the power unit of a thermal power plant to generate thermal and electrical energy. In the course of completing the assigned task, a design calculation of the heating surfaces and a verification calculation were performed, as a result of which the temperatures of the gases, the working fluid and the thermal characteristics of the heating surfaces were determined. A strength calculation of the drum was also carried out and the thickness of its wall was calculated. Harmful emissions from the boiler unit are calculated.

description: An abundance of neural network models and algorithms for diverse tasks on graphs have been developed in the past five years. However, very few provable guarantees have been available for the performance of graph neural network models. In this paper we present the first provable guarantees for one of the best-studied families of graph neural network models, Graph Convolutional Networks (GCNs), for semi-supervised community detection tasks. We show that with high probability over the initialization and training data, a GCN will efficiently learn to detect communities on graphs drawn from a stochastic block model.The thesis starts with general introduction to machine learning and machine learning on graphs, in particular graph neural network models. Then we introduce PAC learning framework, which is a mathematical framework to analyze the performance of a machine learning model. Afterwards, we present a detailed description of stochastic block model and Graph Convolutional Networks, then the main results on learning guarantee. We demonstrate the idea of our proof before giving the detailed proofs. Our proof relies on a fine-grained analysis of the training dynamics in order to overcome the complexity of a non-convex optimization landscape with many poorly-performing local minima. We also show some experimental results and visualization to verify our results.
Modulation of corticospinal excitability in the context of tactile exploration

description: Evidence indicates that the output of the motor cortex is modulated by task conditions with respect to the degree of dexterity involved. However, few studies have examined how corticospinal output could be modulated when the fingers are used for active exploration of patterns or objects. In the present study, we investigated this issue in young healthy participants with transcranial magnetic stimulation (TMS). Corticospinal excitability of the hand motor representation was examined under two task conditions. One condition (TE: tactile exploration task) consisted of exploring raised letters (6 upper case characters, 6-mm high) with the tip of the index finger for tactile recognition. In the second condition (BP: button pressure task), participants depressed a button with minimal force, again using only the index finger. In both tasks, TMS pulses (110% motor threshold) were delivered over the contralateral motor cortex at a delay of 2500 ms in the course of the 5 second trials. Corticospinal excitability was assessed by monitoring changes in the amplitude of motor evoked potentials (MEPs) in the 1st dorsal interossei (FDI) of each hand. Results (n=18) indicated a differential effect of task conditions on corticospinal excitability, with MEPs being larger during TE when compared to the BP task. These findings suggested that corticospinal excitability could be greatly enhanced when the hand is used for sensory exploration in comparison to simple motor performance. However, electromyographic (EMG) activity patterns differed between the two tasks, which could have contributed to differences observed in motor excitability. Therefore, a secondary experiment was performed with a subset of participants (10/18). In this experiment, motor facilitation elicited with the TE task was contrasted with a finger movement (FM) task. In the latter task, participants reproduced the scanning movements performed when they explored the letter, but no stimuli was presented (smooth surface). The pattern of EMG activity was similar to that elicited in the TE task. Yet, comparisons between the two confirmed the task-specific increase in corticospinal excitability with the TE task. Overall, these results highlight the importance of behavioral demands in modulating corticospinal excitability during hand actions, especially when the finger is used for sensory exploration to acquire information about object and surface properties.
Violent offenders' within-treatment change in dynamic risk and protective factors: associations with violent recidivism
Creators: name: Klepfisz, Gabrielle
Publisher: name: Swinburne
Year: 2024

description: This thesis investigates whether within-treatment changes on intermediary treatment targets are associated with violent reoffending at post-treatment follow-up. Taken together, the results do not provide evidence that changes in dynamic risk and protective factors translate into reductions in violence propensity. Furthermore, it remains unclear how protective factors operate in relation to reductions in risk. Developing a greater understanding of change processes and how violent offender treatment works is critical, not only in terms of delivering more effective interventions, but in terms of managing violence risk and promoting public safety.

description: Background Utilising fluorescence optical imaging (FOI), the distribution of an intravenously applied colouring agent indocyanine green (ICG) can be analysed with the potential to identify malperfusion by little to no tissue enhancement. Systemic sclerosis (SSc) is characterised by the presence of digital ulcers reflecting progressive vasculopathy. The objective was to investigate the potential of FOI in the detection of disturbed microcirculation in the hands and fingers of patients with SSc and to link FOI findings to clinical signs of ischemia such as digital ulcers and pitting scars. Methods In this cross-sectional study, 63 patients with SSc and 26 healthy subjects were examined. FOI was performed in all 89 individuals and compared to clinical data and capillaroscopic findings assembled for the SSc cohort. Results Healthy subjects showed initial ICG signals in their fingertips in 93.6%, SSc patients in 78.5% (limited SSc) and 43.2% (diffuse SSc). Moreover, in SSc patients, FOI findings were significantly associated with a late capillaroscopic pattern, disseminated SSc features, a diffuse SSc subtype, and the presence of digital ulcers or pitting scars. Intra- and inter-reader reliability for FOI amounted to κ = 0.786 and κ = 0.834, respectively. Conclusions FOI is able to detect areas of reduced microcirculation in patients with SSc with high association to capillaroscopic findings. The results pave the way for future FOI investigations into its role in the prediction of complications due to an impaired acral perfusion.

description: Parents are widely recognized as playing a central role in the development of child behaviors such as physical activity. As there is little agreement as to the dimensions of physical activity-related parenting practices that should be measured or how they should be operationalized, this study engaged experts to develop an integrated conceptual framework for assessing parenting practices that influence multiple aspects of 5 to 12 year old children’s participation in physical activity. The ultimate goal of this study is to inform the development of an item bank (repository of calibrated items) aimed at measuring physical activity parenting practices. Methods Twenty four experts from 6 countries (Australia, Canada, England, Scotland, the Netherlands, & United States (US)) sorted 77 physical activity parenting practice concepts identified from our previously published synthesis of the literature (74 measures) and survey of Canadian and US parents. Concept Mapping software was used to conduct the multi-dimensional scaling (MDS) analysis and a cluster analysis of the MDS solution of the Expert’s sorting which was qualitatively reviewed and commented on by the Experts. Results The conceptual framework includes 12 constructs which are presented using three main domains of parenting practices (neglect/control, autonomy support, and structure). The neglect/control domain includes two constructs: permissive and pressuring parenting practices. The autonomy supportive domain includes four constructs: encouragement, guided choice, involvement in child physical activities, and praises/rewards for their child’s physical activity. Finally, the structure domain includes six constructs: co-participation, expectations, facilitation, modeling, monitoring, and restricting physical activity for safety or academic concerns. Conclusion The concept mapping analysis provided a useful process to engage experts in re-conceptualizing physical activity parenting practices and identified key constructs to include in measures of physical activity parenting. While the constructs identified ought to be included in measures of physical activity parenting practices, it will be important to collect data among parents to further validate the content of these constructs. In conclusion, the method provided a roadmap for developing an item bank that captures key facets of physical activity parenting and ultimately serves to standardize how we operationalize measures of physical activity parenting.
Political offender or extraditable criminal: The political offence, international order and protection of the individual.

Year: 1994
Subjects: subject: Law.

description: This thesis studies the evolution and current purpose of the political offence exception for the purpose of determining whether there is a continuing role for the exception. It concludes that there is a continuing need for the exception. The thesis examines the coexistence in international law and policy between the demand for international public order, as characterized by the system of extradition laws and treaties, and the need to safeguard the rights of the individual, as reflected in the political offence exception to extradition, international refugee protection and the practice of asylum. There are a number of concerns with the political offence exception as currently applied, namely: (1) Designation of inappropriate acts as political offences; (2) Excessive rigidity and formality by some courts; (3) Excessive judicial discretion; (4) Over-emphasis on efficacy of the act in question; (5) Excessive political influence on decision-making. The thesis proposes an alternative political offence exception test with the following five criteria: (1) the individual should be involved in a dispute concerning political control over the state; (2) the individual should be part of a group which is involved in such a struggle and the act in question must be done in furtherance of that struggle; (3) the exception should not apply to heinous crimes such as crimes against humanity; (4) certain acts such as hijacking should be automatically excluded; (5) there should be proportionality between means and ends.

description: The rise of National Socialism in Germany and the subsequent Nazi takeover in Austria caused an outflow of know-how and talent. The sophisticated academic discipline of art history in both countries was particularly affected. Nazi persecution produced large numbers of involuntary ‘cultural translators’ who fled to other countries and whose decisions and actions determined whether and how knowledge was produced, received, negotiated, transferred and translated.22.

refugee-scholars passed on new standards of scholarship. Their escapes led to a relocation of knowledge, philosophies and cultural practices that triggered substantial changes in the global art world. Studies have already shown the impact of German and Austrian refugee art historians on the British art world.44. A.

Refugee art historians, however, fled to many more countries, consequently leaving their footprints on a much wider geographic area. A small but important number also relocated to Australia.

Plus exactement, nous tenterons, a l'aide d'une approche constructiviste, de determiner comment, niais surtout pourquoi la police et les mass-medias hullois, a travers leur interrelation, en sont arrives a la re-construction "d'evenements". Il sera egalement interessant de soulever les consequences que peut susciter une telle problematique sur les activites policieres et mediatiques, mais aussi a travers "l'opinion publique".

description: Psychiatric illnesses are complex, highly heritable disorders that have substantial implications for both affected individuals and their families. Though genetic testing is currently limited in its clinical usefulness in this area, interest in genetic counseling for psychiatric disorders has a relatively long history and many positive outcomes have been posited. Yet, empirical studies of genetic counseling outcomes have been emerging only more recently. The aim of the current meta-analysis was to analyze the efficacy of genetic counseling and explore potential moderators of its effect. An extensive electronic search was conducted investigating the literature published until July 2016. The initial search resulted in 2367 articles, four of which met the inclusion criteria and were included in the quantitative meta-analysis. Effect size parameters and sample sizes for all variables in each study were included. The efficacy has ben demonstrated both at postintervention and at follow up, with an overall statistically significant effect size of moderate intensity. Implications of this study are discussed in detail.

Rem2 Effects on the Development of Neonatal Mouse Barrel Cortex

description: Rem2 is a small Ras-like GTPase of the Rad/Rem/Rem2/Gem/Kir (RGK) family that is highly expressed in the central nervous system. Previous studies about Rem2 were conducted either in cultured neurons or in the visual system, while we applied Rem2 knockout on the barrel cortices of unilaterally sensory-deprived pups to see its effects on dendritic formation and arborization. We discovered that the loss of Rem2 has resulted in decreases in both the quantity of primary neurites and the sizes of sensory-deprived cells, which was against the normal patterns of sensory deprivation model of the barrel cortex. This phenomenon suggests that Rem2 might play a crucial role specifically on the developmental regulation of deprived barrel cortex layer IV cells, and the underlying mechanisms might differ from those of other neuronal systems.
Effects of acute hypoxia and cold exposure on glucose and fatty acid fluxes in rainbow trout (Oncorhynchus mykiss).
Creators: name: Haman, François.
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1996
Subjects: subject: Biology, Animal Physiology.

description: The first goal of my thesis is to develop a double catheterization method allowing simultaneous infusion of labeled compounds and blood sampling, and to quantify glucose fluxes in resting rainbow trout by continuous infusion of 6-$\sp3$H-glucose (Chapter 2). The new cannulation technique consists of placing both sampling and infusing catheters in the dorsal aorta. Continuous isotope infusion results show that resting glucose turnover is 9.5 $\pm$ 0.8 $\mu$mol $\rm kg\sp{-1}\ min\sp{-1},$ a value 4 to 9 times higher than most rates measured with bolus injection technique. Consequently, the second goal is to quantify the accuracy of the continuous infusion technique in estimating glucose turnover rate. Trout are hepatectomizad and liver glucose production is artificially replaced by a pump infusing unlabelled glucose. Glucose flux measured with the continuous infusion technique using either plasma or whole blood is not significantly different from artificial pump glucose entry rate. Therefore, this result suggests that the bolus injection method widely used in previous trout studies strongly underestimates true glucose flux. Using the continuous infusion technique, my third goal is to investigate the effects of two environmental disturbances namely acute hypoxia and cold exposure, on the rates of glucose and NEFA (non-esterified fatty acids) turnover. My hypotheses are that: (1) during hypoxia, a fuel preference for carbohydrates would lead to an increase in glucose flux and a decrease in NEFA flux; (2) during cold exposure, both glucose and NEFA fluxes would decrease in proportion to metabolic rate depression. The results suggest that no fuel preference is occurring during cold exposure. However, while glucose concentration only shows a slight overall decrease, NEFA concentration increases by 30% after 100 minutes at 6$\sp\circ$C. (Abstract shortened by UMI.)

description: Statement of problem. The ability to walk, fundamental to a good quality of life, is affected by chronic obstructive pulmonary disease. Results. Eleven participants were recruited (May 2001 to January 2002) from a tertiary rehabilitation centre. The patients mean age (+/-standard deviation) was 67.5 +/- 16.6 years, mean percent predicted forced expiratory velocity in one second (FEV1.0) was 26.1 +/- 6.8%, and mean PaO2 was 61.2 +/- 2.3 mMHg. There were no significant period by treatment interactions, or period effects on any outcome. Oxygen significantly outperformed the rollator-style walker on final oxygen saturation (7.8 percent (95% CI 5.0 to 10.6)) and perceived exertion (1.3 points (95% CI 0.1 to 2.4)) but there was no difference noted on distance walked (22.2 metres (95% CI: -76.7 to +32.4)) or speed (-0.02 metres/second (95% CI: -0.13 to 0.08)). Compared to unassisted walks, oxygen improved distanced walked (51.3 metres (95% CI 18.6 to 84.0)) but rollator-style walkers did not (31.4 metres (95% CI -3.4 to 66.2)). Participants indicated that both interventions improved their walking but more participants preferred the rollator-style walker. Conclusions. In spite of oxygen reducing arterial desaturation, rollator-style walkers resulted in similar distance walked compared to oxygen. However, when compared to unassisted walks, oxygen appears to be more effective in increasing distance walked. Rollator-style walkers are a lower cost alternative to oxygen in individuals with COPD and exertional desaturation whose resting arterial oxygen is between 55--65 mmHg. (Abstract shortened by UMI.)
The Role of Maladaptive Emotion Regulation in the Bidirectional Relation Between Sleep and Depression in College Students During the COVID-19 Pandemic

description: Emotion regulation deficits are an outcome and risk factor for both insomnia and depression, suggesting that maladaptive emotion regulation might in part explain the bi-directional links between sleep and depression. The current study tests this hypothesis during the COVID-19 pandemic in emerging adult undergraduate students, a high-risk population for both depression and sleep disturbance. A sample of 154 undergraduate students completed a series of online questionnaires bi-weekly on sleep, depression, and emotion regulation strategies across eight weeks during the early days of the COVID-19 pandemic (April 2nd to June 27th, 2020). Results indicated that sleep disturbance and depression prospectively predicted one another across eight weeks, and both directions were mediated by maladaptive emotion regulation. However, sleep and depression failed to predict change in one another controlling for baseline measures, directly or via emotion regulation. The results suggest that maladaptive emotion regulation is a potential mechanism through which sleep disturbance and depression help maintain high levels of one another in college students during the COVID-19 pandemic. Therefore, emotion regulation deficits are potentially an important target for interventions to interrupt the sleep disturbance-depression cycle.

Applying Egbert's model of Task Engagement (TE) to facilitate the design of engaging features, I created, implemented, and assessed a digital educational escape room (EER) to teach phonemic awareness (PA) through online learning during the COVID-19 pandemic. Data collection and analysis included self-assessment ratings from pre- and post-surveys and analyses of the scores utilizing paired T-tests. I also evaluated open-ended survey questions for TE indicators, integrated TE facilitators to support each design’s changes, and gave the final iteration's group a pre- and post-quiz immediately before and after the experience. Results of the study showed significant increases in mean differences in the pre- and post-surveys, indicating increased confidence in participants’ knowledge, ability to teach, and likelihood of teaching the content. Written feedback gave insight into where participants displayed indicators of task engagement aligned with the TE model. The final group's post-quiz saw an increase in content knowledge gain scores. The cumulative results informed the creation of digital EER design guidelines for use by future researchers and practitioners. The rest of the data will be used for future papers with a focus on phonemic awareness and full-length descriptive EER-DBR research.

description: In a highly heterogeneous computing environment, interoperability among different agent platforms is made possible by the Foundation for Intelligent Physical Agent (FIPA) specification. As long as they are all FIPA-compliant, agents of different systems or providers can communicate and interact directly using Agent Communication Language (ACL). However, neither the FIPA specification nor most of its implementations such as FIPA-OS (FIPA Open Source) fully address potential security threats to agents and agent platforms. In this thesis, we discuss the security concerns in FIPA and propose a two-layer architecture to add security features: a basic FIPA-OS agent platform as the management and communication infrastructure, and a security layer as the security extension. This architecture provides agents with two security-related services: a secure communication service and a secure execution environment service. The secure communication service prevents any eavesdropping or interference from the outside network. The secure execution environment service protects server resources and agent services from unauthorized access. The architecture's design and components are also described in terms of the two security services. In addition, this thesis describes a trust model of the two-layer architecture, which consists of a set of assumptions concerning the relationships of all entities.

description: The development of intravital Förster Resonance Energy Transfer (FRET) is required to probe cellular and tissue function in the natural context: the living organism. Only in this way can biomedicine truly comprehend pathogenesis and develop effective therapeutic strategies. Here we demonstrate and discuss the advantages and pitfalls of two strategies to quantify FRET in vivo—ratiometrically and time-resolved by fluorescence lifetime imaging—and show their concrete application in the context of neuroinflammation in adult mice.

Social Justice

description: This dissertation is comprised of three manuscripts that work together to build a case for critical arts-based research (ABR) approaches to experiential, transformative learning focused on issues of social justice in the built environment. Through critical autoethnography, I challenge traditional ways of doing research and share how my positionality, background, and pathway led to and influence my approach. The transformative, healing ability of ABR is emphasized while multimodal examples from museums, memorials, and monuments that demonstrate the ability of integrated and multimodal arts to evoke emotion and memory in the process of viewing and understanding the past are underscored as components critical to envisioning new and equitable social constructions of the future. Components of a revised design and construction study tour course are informed by transformative experience theory, experiential learning theory, and the learning cycle, and applied through an Indigenous, feminist lens to challenge previously established or understood ways of knowing, seeing, and being.

description: Many modern neural simulators focus on the simulation of networks of spiking neurons on parallel hardware. Another important framework in computational neuroscience, rate-coded neural networks, is mostly difficult or impossible to implement using these simulators. We present here the ANNarchy (Artificial Neural Networks architect) neural simulator, which allows to easily define and simulate rate-coded and spiking networks, as well as combinations of both. The interface in Python has been designed to be close to the PyNN interface, while the definition of neuron and synapse models can be specified using an equation-oriented mathematical description similar to the Brian neural simulator. This information is used to generate C++ code that will efficiently perform the simulation on the chosen parallel hardware (multi-core system or graphical processing unit). Several numerical methods are available to transform ordinary differential equations into an efficient C++code. We compare the parallel performance of the simulator to existing solutions.
Homoallylboration of Aldehydes: Stereoselective Synthesis of E-Alkenes and a Mechanistic Switch to Cyclopropylcarbinylation; An Optimized Synthesis of Fmoc-L-Homopropargylglycine-OH

description: Chapter 1: Allylic boronates undergo stereoselective allylboration with aldehydes, which proceeds through a closed six-membered Zimmerman-Traxler transition state to generate homoallylic alcohols. Analogous to this, cyclopropylcarbinyl boronates react similarly with aldehydes to generate bishomoallylic alcohols stereoselectively. Optically pure α-substituted cyclopropylcarbinyl boronates lead to the enantioselective synthesis of E-alkenes. In the case of α-aryl substituents, the boronates rearrange to styrene byproducts with electron-rich arenes favoring this rearrangement. In addition, while γ-alkyl substituted boronates lead to the expected diastereoselective homoallylation, an anomalous cyclopropylcarbinylation was observed with γ-aryl substituted boronates which was determined to proceed through a mechanism involving ring opening and reclosure. Tuning the electronic properties of the arene substituent can revert the reactivity back to homocrotylation.
description: Chapter 2: The biosynthesis of clickable peptides requires the use of noncanonical alkynyl amino acid homopropargylglycine (HPG). These peptides can be bioconjugated to azide-containing compounds by copper-catalyzed azide-alkyne cycloaddition (CuAAC). One example of this is the generation of peptide libraries for directed evolution of mRNA-displayed glycopeptides that mimic the glycosylated viral protein on the HIV virion surface and induce an immune response. Solid-phase peptide synthesis (SPPS) of evolved peptide sequences requires multigram quantities of the noncanonical alkynyl amino acid Fmoc-L-HPG-OH. An optimized multigram synthesis of Fmoc-L-HPG-OH (18 g, 72% yield over 5 steps) is described herein. A double N-Boc protection was optimized for high material throughput, and the key Seyferth-Gilbert homologation is optimized to avoid racemization.
Neural Mechanisms of Reward Identity Coding and Prediction Error in Olfactory Reversal Learning Using Multivariate Pattern Analysis

description: Decision making and reward learning involve the representation of choice, the anticipation of choice outcome, value assignment to choices by their attributes, incorporating additional restraints, making value-based decisions, and according to the outcome, reevaluating and adjusting the representation and valuation. Most of these steps require conditional valuation and updates of valuation based on the context and characteristics of a reward to grant flexibility and specificity in choice. Yet the field of decision-making has frequently overlooked this need for specificity in pursuit of pure valuation of “how good it is”. To address this issue, the current study used multivariate pattern analysis on fMRI data collected during an olfactory trans-reinforcer reversal learning task to elucidate the role of the orbitofrontal cortex (OFC) in reward identity anticipation, and its relationship with midbrain identity prediction error (iPE). I found significantly above chance decoding accuracy of expected reward identity in left lateral OFC during anticipation of the reward. Moreover, identity decoding accuracy in lateral OFC in the first trial after a reversal trial was significantly correlated with the univariate midbrain iPE in the reversal trial. These findings suggest that lOFC encodes value-independent reward information, and the identity information flow between lOFC and midbrain may support learning new reward identities when that feature of expectations is violated on reversals. This study confirms the role of OFC in constructing a cognitive map and helps build a more comprehensive picture of midbrain-cortical function in reward learning.

description: Because of the prevalence of mental health disorders in today’s society, it is important that adolescents are aware of various interventions to reduce their risk of developing these disorders and improve their overall wellbeing. The current study examined how participating in team relative to individual sports has beneficial effects on an adolescent’s prosocial functioning and mental health outcomes. This study was a secondary data analysis of the Adolescent Brain Cognitive Development (ABCD) study, which is a longitudinal study on child health and development in the United States. Data from the first three years of the ABCD study were used, and the sample size with complete data was N = 3,187. Males were slightly overrepresented (54.1%, N = 1,724), and participant ages ranged from 10 to 14 years (M = 11.51, SD = 0.68). We hypothesized that team sport participation would predict better social functioning and internalizing difficulties, but that these effects would be mediated by higher DHEA levels, greater number of close friendships at time 1 and better overall fitness. The individuals who participated in team sports or both team and individual sports exhibited higher levels of prosocial functioning and lower levels of anxiety, depression, social problems, and internalizing problems across the three time points, but did not predict improved levels of internalizing problems or prosocial functioning. The only exception to this pattern was that participants involved in team sports showed decreased levels of withdrawn depression. The only evidence of mediation was with withdrawn depression. The number of close friends partially mediated the effect of sports participation in the previous year on withdrawn depression. Higher levels of DHEA were associated with lower levels of anxious depression in the third year. These findings suggest that sports participation, particularly team sports, could potentially serve to prevent internalizing problems in adolescents.

description: Mumps virus is member of the paramyxovirus family of viruses. The Urabe strain of mumps was attenuated to produce a vaccine that was introduced in several countries, but withdrawn from the market when it was discovered to be insufficiently attenuated. Two vaccine-associated Urabe viruses have been shown to have different tropisms in tissue culture. Gw7, isolated directly from the vaccine and which has been shown to be attenuated in an animal model, shows limited growth in human lung epithelial cells (A549) compared to monkey kidney cell line (Vero). 1004 10/2 is a virus isolated from a patient with post-vaccination meningitis caused by the Urabe vaccine and this virus grows to high titres in both A549 and Vero cells. A limited number of genetic differences between Gw7 and 1004 10/2 have been identified that must account for the growth differences in tissue culture. Using a combination of functional assays and genetic analysis of other Urabe viruses with growth patterns similar to Gw7 or 1004 10/2, it was demonstrated that the failure of Gw7 to replicate well in A549 cells is not due to differences in the sensitivity to interferon, differences in receptor binding, the M protein, or the SH protein. The results implicated the L protein. This was further supported by the observations of reduced protein synthesis and RNA synthesis in A549 cells compared to Vero cells. This suggested that genetic differences between the viruses caused differences in the function of the L protein during transcription of mRNA, which resulted in the observed tropisms.
Development of a Windows(TM) three-dimensional sound system using binaural technology.

description: It is anticipated that 3-D sound will become a major component in virtual reality environments. In this thesis, we investigate the development of a Windows(TM) 3-D sound system using binaural technology. This work should eventually be integrated in complex virtual environment software. The 3-D sound effects are achieved by applying a filter pair representing audio cues from a specific point in space to the left and right channels of headphones. As a first step, an offline 3-D audio file generation system is developed, and effects such as sound reflections in a virtual rectangular room are added to this system. The real-time implementation is considered next. The first approach tested for the real-time implementation uses the time domain convolution of a sound source signal with head-related transfer functions, but the computational load of this approach is such that it cannot run in real-time at audio sampling rates. As an alternative, a second approach with a Fast Fourier Transform overlap and save technique is used to reduce the computational load, and a real-time implementation at audio frequencies is therefore successfully achieved.

description: The prevention and control of new and existing hepatitis B virus (HBV) infections remains an important global health concern. Despite current global immunization efforts, new HBV infection continues to occur. It is estimated that about 350 million people worldwide are currently afflicted by viral persistence. This body of work explores the possibility of developing improved prophylactic and possibly therapeutic vaccines against HBV using DNA technology. It has become well established that the effective control of HBV infection requires the development of strong humoral and cell mediated immunity (CMI) including the production of the pro-inflammatory cytokines interferon (IFN) gamma and tumor necrosis factor (TNF) alpha that are associated with a CMI response. In the absence of these responses infection is not resolved and persistence ensues. The ability of DNA (either in the form of a DNA vaccine or as immunostimulatory DNA sequences in combination with protein antigens) to stimulate both humoral and cellular immune responses that include the production of IFNgamma and TNFalpha, makes them attractive candidates for development of novel prophylactic and therapeutic agents in the struggle against HBV infection. This work demonstrates that immunization strategies that include DNA technology were capable of controlling HBV gene expression in a hepatitis B surface antigen transgenic mouse model as well as provide protection against infectious HBV challenge in chimpanzees. The quality of the immune responses induced in the chimpanzees suggests that the therapeutic potential of these immunization strategies observed in the mouse model may also extend to higher primates.
