description: We present an analysis of deep Hubble Space Telescope (HST) multi-band imaging of the BDF field specifically designed to identify faint companions around two of the few Lyα emitting galaxies spectroscopically confirmed at z ∼ 7. Although separated by only 4.4 proper Mpc these galaxies cannot generate H ii regions large enough to explain the visibility of their Lyα lines, thus requiring a population of fainter ionizing sources in their vicinity. We use deep HST and VLT-Hawk-I data to select z ∼ 7 Lyman break galaxies around the emitters. We select six new robust z ∼ 7 LBGs at Y ∼ 26.5-27.5 whose average spectral energy distribution is consistent with the objects being at the redshift of the close-by Lyα emitters. The resulting number density of z ∼ 7 LBGs in the BDF field is a factor of approximately three to four higher than expected in random pointings of the same size. We compare these findings with cosmological hydrodynamic plus radiative transfer simulations of a universe with a half neutral IGM: we find that indeed Lyα emitter pairs are only found in completely ionized regions characterized by significant LBG overdensities. Our findings match the theoretical prediction that the first ionization fronts are generated within significant galaxy overdensities and support a scenario where faint, "normal" star-forming galaxies are responsible for reionization.
Deaf people’s experiences, attitudes and requirements of contextual subtitles: A two-country survey
Creators: name: Hersh, Marion
Publisher: name: Swinburne
Year: 2024

description: Subtitles are text versions of the speech content of television and other audiovisual media. The paper discusses the results of a survey of deaf people1 in Poland and the UK on their experiences of, attitudes to and requirements for subtitles, including for the representation of emotions and contextual features. The results demonstrated the importance of subtitles, and that they considerably improved comprehension for the great majority of respondents. The overwhelming majority preferred verbatim subtitles, but attitudes to other suggested features were very varied, indicating the need for subtitle personalisation. This has not been considered previously and would now be feasible due to advances in technology.
Critical engagements : empathy, subjectivity and changing narratives of water resources through participatory video

description: This article engages a critical feminist analysis of a community-based participatory video (PV) process focused on water and sanitation issues in underserved settlements of Accra, Ghana and Cape Town, South Africa. With focus on emotions and empathy, we highlight these concepts in relation to participant narratives and shifting subjectivities. In so doing, we consider how arts based engagement (in this case, through participatory video), might serve to foster new ways of relating to water resources and water infrastructures. The analysis highlights how the participants themselves reflect on PV as a vehicle for personal transformation, knowledge co-creation and a ‘watered’ subjectivity. We find that the PV process helps to uncover and identify knowledge gaps on water governance by enabling individuals and communities--often unheard—to participate in civic and political debates around resource governance. While many positive elements were emphasized, we also suggest that there is a need for critical engagements that also address challenges associated with these methods, including limitations with respect to fostering fundamental long-term change in communities. In the conclusion, we broaden beyond our individual case studies to consider implications for community engagement and citizenship practices in the realm of natural resource governance.

description: Does gender determine the choice to take science? When participation rates of men and women in scientific and mathematical fields are compared, all countries with statistical information have reported significantly lower participation rates for women (Heller & Ziegler, 1996). This was not shocking news. Under representation of women in sciences has been the norm since society frequently views women as lacking in ability, although there is no convincing evidence for different abilities in boys or girls (Bandura, 1997; Joyce & Weil, 1996; Weiner, 1985) Gifted girls face many obstacles in their academic careers The literature review deals with two main areas, parental support and school attitude. The first area relates to parental support that includes parental expectations, gender roles, parental encouragement, and encouraging agency. Then school attitude, including socializing agents, attributional feedback, self-efficacy, self-concept, equity, teachers, fun and prior experience, and peers was examined. This study attempted to explore the perceptions of gifted girls regarding school environment and parental support influencing their choices to take extracurricular science classes. This will add knowledge to the field of gifted education, specifically that of within-gender differences of gifted girls. Moreover, by knowing influential factors within the school environment and parental realm, educators and parents will be better equipped to nurture these in other gifted girls, thus, changing these 'obstacles' into positive challenges.

description: Epidemiological research from the past twenty years has consistently shown cannabis- impaired driving doubles the risk of a car crash (Hartman & Huestis 2013). This is primarily due to the predominant psychoactive cannabinoid found in cannabis, ∆9-tetrahydrocannabinol (THC), which can impair numerous safety-critical driving tasks, such as divided attention, reaction time, decision making, and risk-taking. However, efforts to predict driving impairment are challenged by individual variability in response to cannabis.
description: The causes of individual variation are broadly explained by frequency of use, biological/genetic differences, and psychological vulnerabilities, how these manifest in driving performance is less clear. The underlying challenge is a single model which explains performance amongst all cannabis users does not exist.
description: The objective for this body of work is to develop a model using a systems-based approach to research individual variation in cannabis-induced driving impairment. Chapter 1 lays out the objective, background, problem statement, and current state of research. Chapter 2 introduces the prospect of using subjective perceptions of state to predict driving performance, as these perceptions are one of many manifestations of individual differences. Chapter 3 examines the relationship between subjective effects and driving performance across a broader range of users. Chapter 4 examines the relationship between brain activity, interactions between subjective effects, and driving performance. Chapter 5 lays out the key findings, implications of these findings, and future research goals.
description: The key findings of this research are as thus. To understand driving impairment, you need to understand driver’s perception of impairment and their physical impairment. Generalizability of individual perceptions of impairment is lacking, but interactive effects show potential. Acute cannabis intoxication manifests as an increase in the frequency and duration of driving errors. Subjective effects and brain activity jointly explain more of the differences in simulated driving performance, than either in isolation.
description: The significance of this research is that the complex interactions between subjective perceptions and brain activity may predict cannabis impairment across a wider range of users. Furthermore, the examination of error frequency and duration, as opposed to continuous measures of driving performance, is a novel approach to modeling driving performance. The results provide guidance for future modeling efforts, suggesting error frequency may be an effective tool for modeling impairment, whereas error duration is not.

description: The increasing availability of mobile technologies incorporating universal design features has provided a more affordable assistive technology solution for many people with disabilities. However, several authors caution that there are possible negative by-products associated with this trend, highlighting the need for further research into the benefits and challenges of using mainstream devices as assistive technologies. This paper reports the interim findings of a project involving the trial of iPads with two participant co-researchers who have physical disabilities and ten residents of a high support institution for people with disabilities. The project methodology involved: 1) evaluation of participants' use of the devices; 2) pre- and post-intervention testing using goal attainment scaling; 3) training and ongoing support in use of the device; and 4) analysis of user satisfaction with the iPad using a modified version of the Quebec User Evaluation of Satisfaction with Assistive Technology instrument. The study contributes to the growing evidence-base exploring the potential of mainstream mobile devices as assistive technologies and highlights areas for further research and development.

description: We measure the bulk flow of the local Universe using the 6dF Galaxy Survey peculiar velocity sample (6dFGSv), the largest and most homogeneous peculiar velocity sample to date. 6dFGSv is a Fundamental Plane sample of ∼104 peculiar velocities covering the whole Southern hemisphere for galactic latitude |b| > 10°, out to redshift z = 0.0537. We apply the ‘minimum variance’ bulk flow weighting method, which allows us to make a robust measurement of the bulk flow on scales of 50 and 70 h−1 Mpc. We investigate and correct for potential bias due to the lognormal velocity uncertainties, and verify our method by constructing Λ cold dark matter (ΛCDM) 6dFGSv mock catalogues incorporating the survey selection function. For a hemisphere of radius 50 h−1 Mpc we find a bulk flow amplitude of U = 248 ± 58 km s−1 in the direction (l, b) = (318° ± 20°, 40° ± 13°), and for 70 h−1 Mpc we find U = 243 ± 58 km s−1, in the same direction. Our measurement gives us a constraint on σ8 of 1.01+1.07−0.58. Our results are in agreement with other recent measurements of the direction of the bulk flow, and our measured amplitude is consistent with a ΛCDM prediction.

description: We explore star formation histories (SFHs) of galaxies based on the evolution of the star formation rate stellar mass relation (SFR-M∗). Using data from the FourStar Galaxy Evolution Survey (ZFOURGE) in combination with far-IR imaging from the Spitzer and Herschel observatories we measure the SFR-M∗ relation at 0.5 < z < 4. Similar to recent works we find that the average infrared spectral energy distributions of galaxies are roughly consistent with a single infrared template across a broad range of redshifts and stellar masses, with evidence for only weak deviations. We find that the SFR-M∗ relation is not consistent with a single power law of the form at any redshift; it has a power law slope of α ∼ 1 at low masses, and becomes shallower above a turnover mass (M0) that ranges from 109.5 to 1010.8 M⊙, with evidence that M0 increases with redshift. We compare our measurements to results from state-of-the-art cosmological simulations, and find general agreement in the slope of the SFR-M∗ relation albeit with systematic offsets. We use the evolving SFR-M∗ sequence to generate SFHs, finding that typical SFRs of individual galaxies rise at early times and decline after reaching a peak. This peak occurs earlier for more massive galaxies. We integrate these SFHs to generate mass growth histories and compare to the implied mass growth from the evolution of the stellar mass function (SMF). We find that these two estimates are in broad qualitative agreement, but that there is room for improvement at a more detailed level. At early times the SFHs suggest mass growth rates that are as much as 10× higher than inferred from the SMF. However, at later times the SFHs under-predict the inferred evolution, as is expected in the case of additional growth due to mergers.

description: Writing in English as a second or additional language has become an important skill that can be applied in many areas of human activity. As we become a society within which written text is an important instrument that helps create new ideas, services, and products, English text is often used as a preferred mode of communication. Traditionally approaches in teaching how to write in English range from pedagogies that center function or text structure and grammar, content or information, and personal expression. Writing instructors can choose elements to include in their lessons after considering the instructional goals and writing elements their students may benefit from.
description: Although the many approaches to writing instruction consider different aspects of writing such as textual patterns, sentence structure, and writer’s voice, there is still a gap in how we understand idea generation and development and what they may look like in student-generated texts. Because it is less challenging to evaluate writing using linguistic markers like quantity of errors, the amount of text written within specific time constraints, complexity of sentences, and caliber of academic words, studying how ideas may present themselves in second language writing has not been explored to the extent that more concrete language criteria of writing have been.
description: This research project aims to move the scale in Second Language Writing (SLW) research and pedagogy from language focused criteria of what is good writing towards how we can start including ideas and their development in writing instruction. To understand how ideas manifest in students’ texts, I collected multiple written drafts from students enrolled in an 8-week intensive English language course, completed individual conferences where feedback on writing was provided, and asked the students to rewrite their initial drafts. After the revisions were complete, I interviewed the students, and posed questions on the critical moments when their ideas changed from one draft to another to reveal writing processes. I then coded data and completed a thematic analysis to build a case for each student to highlight their engagement in the process of idea development. After analysis of each individual case study was concluded, I compared the four features of creativity, presented conclusions on similarities between case studies, and described their relationship.
description: The description of the four creativity features fluency, flexibility, originality, and elaboration contributes to our understanding of writing processes and provides an additional path to a writing pedagogy that makes space for idea generation and development in addition to commonly used linguistic markers used to define writing quality.

description: Stem size distribution (SSD), which describes tree frequencies in diameter classes within an area, has a variety of direct and indirect applications that are critical for forest management. In this study, we evaluated which structural characteristics derived from Airborne Laser Scanning (ALS) data were best able to differentiate between unimodal and bimodal stands in a managed boreal mixedwood forest in Alberta, Canada. We then used wall-to-wall ALS data to predict (for 20 m-by-20 m grid cells) the parameters of a Weibull SSD in unimodal cells, and a Finite Mixture Model (FMM) in bimodal cells. The resulting SSDs were evaluated for their fit to ground plot-measured SSDs using an Error Index (EI). We found that the variance of ALS return heights was the best metric for differentiating between unimodal and bimodal stands, with a classification accuracy of 77%. Parameters of both the Weibull and FMM distributions were accurately predicted (r2 ~ 0.5, Root Mean Square Error (RMSE) ~ 30%), and that differentiating for modality prior to estimating SSD improved the accuracy of estimates (EI of 49.13 with differentiation versus 51.31 without differentiation). Unique to our presented approach is the stratification by SSD modality prior to the modelling of distributions. To achieve this, we apply a threshold to an ALS metric that allows SSD modality to be distinguished for each cell at the landscape level, and this a priori information is then used to ensure that the appropriate distribution is modelled. Our approach is parsimonious and efficient, enabling improved accuracy in SSD estimation across diverse landscapes when ALS data is the sole data source.

description: A computerized timetabling system developed at University of Ottawa is presented. The system is built on a logic programming model which uses first order logic to define first order and second order constraints in timetabling. Information about courses, professors, and student programs is collected for each academic year and used in the process of constructing timetables. The time schedule produced by the system takes into account course conflicts, professor availability, professor teaching preferences, pre-assignments, classroom location choices, and many other important factors that affect its user satisfaction level. Along with the system's ability to include factors such as professor availability, professor teaching preferences and classroom location, the analysis of test results at the University of Ottawa shows a large improvement in the time utilization and seating usage of classrooms, compared to the corresponding timetables that are produced by the traditional manual processes.

description: Increasing access to Information and Communication Technologies, and a growing awareness of the role that the Internet plays in enabling participation in the democratic process has highlighted the importance of ensuring that all government and parliamentary websites are accessible to all Australians. The United Nations Convention on the Rights of Persons with Disabilities, of which the Australian Government is a signatory, recognises the role that web accessibility plays in a democratic society through Article 9 focusing on accessibility and Article 29, which protects the right of people with disability to participate in political and public life. However, the review of major Australian political party websites reported in this paper reveals a mismatch between Australia's commitment to accessibility and the reality. This paper reports the findings of the review and presents a case study on the redesign of the Dignity for Disability website as a roadmap for web developers on practical strategies for redesigning websites to meet international web accessibility guidelines.

description: It has been shown that statistical persistence in stride intervals characteristics exist during walking, running and cycling and were speed- dependent among healthy young adults. The purpose of this study was to determine if such statistical persistence in stride time interval, stride length and stride speed also exists during self-paced continuous stairmill climbing and if the strength is dependent on stepping rate. Stride time, stride length, and stride speed were collected from nine healthy participants during 3 min of stairmill climbing at 100, 110, and 120% of their preferred stepping rate (PSR) and 5 min of treadmill walking at preferred walking speed (PWS). The amount of variability (assessed by standard deviation and coefficient of variation) and dynamics (assessed by detrended fluctuation analysis and sample entropy) of the stride time, stride length, and stride speed time series were investigated. The amounts of variability were significantly higher during stairmill climbing for the stride time, stride length, and stride speed and did only change with increased stepping rate for stride speed. In addition to a more irregular pattern during stairmill climbing, the detrended fluctuation analysis (DFA) revealed that the stride length fluctuations were statistical anti-persistent for all subjects. On a group level both stride time and stride speed fluctuations were characterized by an uncorrelated pattern which was more irregular compared to that during treadmill walking. However, large inter-participant differences were observed for these two variables. In addition, the dynamics did not change with increase in stepping rate.
Evaluating the abuse potential of extended-release polyethylene oxide matrix tablets

Subjects: public abstract

description: Development of abuse-deterrent formulations is one of the approaches taken by the pharmaceutical industry to address the ongoing opioid crisis. Various approaches have been used to formulate abuse-deterrent dosage forms (ADFs), and polyethylene oxide (PEO) matrix tablets prepared by direct compression followed by sintering above the PEO melting temperature have shown excellent abuse-deterrent properties. Additional testing on the granules obtained following grinding abuse-deterrent tablets showed that tablets prepared using the direct compression method failed to maintain abuse-deterrent properties, and the smallest particles formed using simple grinding techniques may result in a higher risk for continued illicit drug use. A minimal physiologically based pharmacokinetic (PBPK) model for oxycodone, an opioid commonly abused through nasal insufflation, was developed to quantitively assess the abuse potential of manipulated ADFs. The model was built using available literature data for plasma and brain oxycodone concentrations in rats and humans. The model was extended to include two compartments to describe the drug release from the ADF granules and the absorption of oxycodone following nasal insufflation. The results from the extended minimal PBPK model for nasal insufflation of different sizes of granules obtained from prototype ADF tablets showed that the smallest ADF granules had both a high drug content and high abuse potential and were most likely to be inhaled by abusers.
description: To further assess the potential for abuse, a population PK model was built to characterize the disposition of oxycodone following nasal absorption from abuse-deterrent granules in order to assess the sources of PK variability and to further evaluate the nasal abuse-deterrent properties of opioid-containing drug products. Particle size was shown to have a significant effect on the drug’s absorption rate and bioavailability. Additional simulations using this popPK model showed that the amount of drug in the smallest ADF granules still possessed sufficient opioid for potential nasal abuse. These results suggest that evaluation of the drug content and drug release from the smallest granules (< 500 µm) formed following ADF tablet manipulation, especially the particle sizes most likely to be inhaled, could contribute to the identification of drug products able to maintain their abuse-deterrent properties and those with significant abuse potential despite the abuse-deterrent properties of the original tablet.

description: Noisy Intermediate-Scale Quantum (NISQ) devices, while accessible via cloud platforms, face challenges due to limited availability and suboptimal quality. These challenges raise the risk of cloud providers offering fraudulent services. This emphasizes the need for users to detect such fraud to protect their investments and ensure computational integrity. This study introduces a novel dynamic fingerprinting method for detecting fraudulent service provision on quantum cloud platforms, specifically targeting machine substitution and profile fabrication attacks. The dynamic fingerprint is constructed using a \textit{single} probing circuit to capture the unique error characteristics of quantum devices, making this approach practical because of its trivial computational costs. When the user examines the service, the execution results of the probing circuit act as the device-side fingerprint of the quantum device providing the service. The user then generates the user-side fingerprint by estimating the expected execution result, assuming the correct device is in use. We propose an algorithm for users to construct the user-side fingerprint with linear complexity. By comparing the device-side and user-side fingerprints, users can effectively detect fraudulent services. Our experiments on the IBM Quantum platform, involving seven devices with varying capabilities, confirm the method's effectiveness.

The silver-lead-zinc veins of the Kokanee Range, British Columbia.

Subjects: subject: Geology.

description: In the Kokanee Range, southeastern British Columbia, more than 370 Ag-Pb-Zn vein and replacement deposits are hosted by the Middle Jurassic Nelson batholith and surrounding Cambrian to Triassic metasedimentary rocks in the hangingwall of the Slocan Lake Fault, an Eocene, east-dipping, low angle normal fault. K-Ar and step heating $\sp{40}$Ar/$\sp{39}$Ar analyses on hydrothermal vein and alteration muscovite indicate that hydrothermal fluids were forming vein and replacement deposits 58-59 Ma ago. A 100 Ma time interval is therefore documented between batholith emplacement and spatially associated mineralisation, ruling out any genetic link between the two. The Pb isotope compositions of galena permit the deposits to be divided into four groups that result from mixing Pb leached from three reservoirs located in the local, upper crustal country rocks, the lower crust, and the upper mantle. Sulfur was derived from local country rocks, and carbon was derived from mantle CO$\sb2$ degassing. The $\rm \delta\sp{34}S\sb{sulphide},$ $\rm \delta\sp O\sb{quartz},$ $\rm \delta\sp O\sb{siderite},$ and galena Pb isotopic ratios from veins display regional zonations revealing fluid flow paths of a large, fossil hydrothermal system. Regional isotopic zonations are controlled by deep fracture zones, such as the Slocan Lake Fault, which channelled lower crustal and mantle Pb, and mantle CO$\sb2$ to higher crustal levels where mixing occurred with upper crustal fluids which had leached local sulfur and upper crustal Pb. Three contrasting fluids are identified: (i) a high salinity, deep-seated and isotopically crust-equilibrated fluid; (ii) a low salinity upper crustal fluid of evolved meteoric origin; (iii) a late stage meteoric fluid. Silver-lead-zinc veins from a distinct type of vein deposit characterised by their mineralogy, form, and metal content. Silver-lead-zinc veins are late orogenic features of metamorphosed sedimentary basins within Pb-Zn metallogenic provinces and commonly occur near large crustal faults.
The geology and palladium mineralization of the southern Roby, Twilight, and High Grade zones of the Lac des Iles Mine, western Superior province of Canada

description: The Lac des Iles Pd mine is hosted by 2.69 Ga. gabbroic rocks of the Lac des Iles Intrusive Complex in the southern Wabigoon subprovince, Superior province of Canada. Economic mineralization, ∼ 159 Mt at 1.55 g/t Pd before major mining in 2001, occurs in the Roby zone of the Mine Block Intrusion. The southern Roby and Twilight zones contain gabbroic/gabbronoritic intrusions with complicated textures, such as brecciation and magma mingling. Ore has low concentrations of sulphide (∼ 1-3 vol. %) and high Pd/Pt of ∼8-10. Detailed mapping and geochemical analysis of the southern Roby and Twilight Zones indicate that early leucocratic rocks are barren and that the bulk of the platinum group elements (PGE) were introduced by late melanocratic magmas. Sulphur correlates positively with base and precious metals. In addition to exsolution of pentlandite and chalcopyrite from pyrrhotite, the data suggests a magmatic origin of the PGE where immiscible sulphide melt concentrated PGE. Fractionation of olivine, chromite, and high temperature platinum group minerals likely resulted in high concentrations of Pt-group PGE/Ir-group PGE in the parental magmas. Extreme enrichment of Pd and high Pd/Pt ratios in the late melanocratic magmas is interpreted to be due to incorporation of earlier formed sulphide melt. The High Grade Zone, on the eastern margin of the Roby Zone, contains only ∼7 vol. % of the Roby Zone but hosts ∼ 35% of the Pd at the mine. The zone is intensely altered and contains two mineral assemblages: (a) millerite + siegenite +/- chalcopyrite +/- pyrite co-existing with hornblende + plagioclase +/- quartz +/- carbonate, and (b) pyrite +/- chalcopyrite with chlorite + actinolite +/- albite +/-quartz +/- carbonate. The ore is high in Pd and Pd/Pt (mean of 16.5; max. 25) compared to the southern Roby and Twilight zones. Although plots of S versus Se and base and precious metals show scatters, positive correlations are observed for Se versus Te and less mobile elements, such as Pt, Ni and Co. The data suggest that magmatic mineralization was followed by hydrothermal transport of mobile elements. Hydrothermal activity enriched the zone by up to 40 ppm Pd. The lack of fluid pathways and the distribution of the zone adjacent to mineralized breccia are consistent with magmatic-hydrothermal activity by aqueous fluids exsolved from the parental magmas of the Roby zone. Geochemical and Pb, Sr, and Nd isotope compositions from the Mine Block Intrusion suggest that the parental magmas were derived through high degrees of partial melting of a previously metasomatized depleted mantle source. The Lac des Iles Intrusion, as well as the surrounding mafic/ultramafic and sanukitoid suite of intrusions, display subduction influenced geochemical signatures, such as negative HFSE and enriched LILE.

description: Kaposi's sarcoma (KS) is a multifocal proliferative disorder that is commonly associated with individuals who suffer some degree of reduction in immune competence. Therapy for this disorder varies and is determined by the seriousness of KS disease in the patient as well as the patient's ability to tolerate the different treatments. A better understanding of how KS arises would allow investigators to tailor therapies that would be more specific to KS and less detrimental to the individual. In this work, cell lines were established from skin biopsies taken from KS lesions of individuals with AIDS. The KS1 cell line presented as a combination of adherent and non-adherent cells that proliferated aggressively without senescence. The KS4 cell line presented as the typical spindle cell population that proliferated aggressively, but eventually senesced. Both cell lines were positive for the presence of Factor VIII-related antigen (FVIII) and the production of IL-6 and basic Fibroblastic Growth Factor (bFGF). When the association with Human Herpesvirus 8 (HHV8) was assessed, the virus proved undetectable in both cell lines. The response of the KS cell lines to Doxorubicin, Etoposide, and ALX40-4C was assessed. (Abstract shortened by UMI.)

description: The XML-based interoperable characteristics make enhancing security for XML Web Services a lot different from that of the traditional network-based applications. SSL VPN gateways are usually used to provide security for traditional network-based applications, but not for Web Services. This thesis presents an integrated security solution for securing both traditional network-based applications and Web Services. The integrated security solution includes a VPN framework and a Web Services framework. Considering that we have already had an SSL VPN gateway developed by our lab, we take it as the motherboard of the solution and the VPN server of the gateway as the security functional part of the VPN framework. As the highlight of this thesis project, a Web Services security component, also the security functional part of the Web Services framework, has been developed, implemented and integrated with the SSL VPN gateway to get the integrated security solution. The problem of applying ECC over binary fields for XML security, SOAP message security and Web Services security to make the Web Services security component share the same set of ECC keys with the VPN server on the gateway has been studied. Tools for reading ECC keys and certificates from the BUL's key files have been developed. Methods to adopt the ECC key files to ensure security of Web Services have also been developed. To the best of our knowledge, there is no previous work on adopting ECC keys over binary fields for Web Services security. The integrated security solution we present in this thesis is the prototype of a network device that has functions of three gateways: a VPN gateway, a Web Services security gateway and a Web Services gateway.

description: The main objective of this study was to compare the total suspended solids (TSS) removal efficiency of a modified sedimentation tank to that of a conventional tank The experimental tank was designed for flow to pass over a series of inclined plates. It had a much shallower flow through zone and the inclined plates were situated just below this zone. The inclined plates were added to provide a quiescent settling zone for the falling particles and to act as a barrier to prevent scour of settled particles. A conventional horizontal flow sedimentation tank was also used in this study. The two designs were run in parallel and a highly concentrated clay suspension was passed through both tanks. The TSS concentrations of both the influence and effluent streams were measured. The response of both designs to different parameters such as sampling time, depth over the inclined plates, flowrate, inclined plates spacing and inlet TSS concentration was observed. The tank with the inclined plates (at the smallest spacing) proved to have an equal to slightly high removal efficiency and a slightly better reaction to the change of parameters. This tank also proved to have less dead volume than the control tank. Since the reduction in flow through volume proved to be as good and slightly better than the control tank the concept deserves further research. It has the potential to permit considerable tank depth reductions while retaining efficiency.
Evaluating private pesticide applicator curriculum using the hierarchy of controls

description: Pesticides have been a mainstay in agriculture for thousands of years. However, worker protections and safety training are a comparably recent endeavor, only taking place in the last two centuries. To apply restricted use pesticides on farms, workers must possess a private pesticide applicator certification, which can be obtained from the state or county level. This paper provides a review of the curriculum provided by four of the top agriculture states in the United States: Iowa, Illinois, California, and Texas. The primary target of this paper is to establish the differences between the four selected states, and to establish whether or not the hierarchy of controls is used to develop prevention materials. The curriculum review suggests that while overall information is consistent between the states selected, the method of presentation and area of greatest focus varied from state to state. It also suggests that the hierarchy of controls can be viewed as a guiding principle for the selected curriculum. Future studies would be necessary to evaluate the quality of learning techniques used, as well as for comparisons with other states.
Pupillometric assessment of excessive daytime sleepiness in narcolepsy-cataplexy.

description: Ten untreated patients with narcolepsy-cataplexy and ten age and sex matched normals between the ages of 20 and 71 underwent pupillometric analyses immediately prior to each of five Multiple Sleep Latency Test (MSLT) sessions. Although narcoleptics were sleepier in terms of both their Stanford Sleepiness Scale (SSS) ratings and their latencies to sleep onset, the baseline pupil diameter, pupillary light reflex and pupillary orienting response did not differentiate between groups. Narcoleptics did, however, exhibit a significantly greater frequency of spontaneous oscillations in the dark-adapted state than did controls. These findings indicate that pupillary stability may serve as a supplementary diagnostic tool for narcolepsy-cataplexy. The results are discussed with the view that psychosensory restoration of alertness, among other extraneous variables, must be controlled for when utilizing pupillometric techniques. A review of the literature indicates a variety of methodological and statistical shortcomings that must be amended. Suggestions are made for improving the reliability and validity of the pupillometric approach.

description: Caspase-7 (C7) is a cysteine protease involved in apoptosis. C7 has also been shown to play a role in the etiopathogenesis of several human diseases including neurodegenerative diseases (e.g. Parkinson’s disease and Alzheimer’s disease) and inflammatory conditions. Despite the substantive therapeutic value and high degree of interest in drugs targeting C7, there are currently no pharmaceutical inhibitors of C7 or any other caspase. My research approach used fragment-based drug discovery (FBDD) and natural products screening in order to identify novel caspase-7 effectors, which may serve as drug leads. I used a biochemical, structural, and computational workflow to gain insight into the mechanism of inhibition of a developing pharmacophore targeting the C7 allosteric site identified by FBDD. Additionally, I attempted to streamline the characterization of hits from screening of fractionated natural products libraries, a major obstacle currently limiting their utility in the broader landscape of drug discovery research, using an integrated analytical chemistry and computational approach. Here I present novel fragment-based inhibitors targeting the C7 allosteric site, elucidate how these inhibitors affect C7 structure and catalysis, and demonstrate the value of continued investigation of natural products to identify novel C7 inhibitors. Additionally, I develop a novel process for structural characterization of samples from fractionated natural products libraries reducing i) the amount of material needed for structure determination and ii) the number of assays needed to identify a hit. My work advances drug targeting efforts for C7 and provides valuable insight into the mechanism of allosteric inhibition of C7. This provides a springboard for future drug discovery efforts targeting C7, as well as allosteric drug discovery efforts in similar proteins. My work also puts forth a significant innovation to screening natural products, which can be used to reduce the cost and improve the accessibility of natural products screening for drug discovery.

description: Various methods have been used in the past to implement the control structures of digital computers. Microprogramming is regarded as the most versatile approach to this end. It reduces the complexity and increases the flexibility of the control unit. Furthermore, dynamic microprogramming allows modification or reconstruction of the system architecture as viewed at the machine language level; such a system can be based on the "emulation" concept which utilizes microprogramming techniques to interpret various system architectures at the machine language level. A study of the process of emulation is the subject of this thesis. The thesis describes the main features of both the target and the host systems that affect the emulation process. The principles underlying the design of an emulator are also discussed. For this purpose, a Data General NOVA system has been emulated on the MICRODATA 1600 and evaluated. The thesis concludes with some recommendations for further work.

description: Optical technology is crucial to the heads-up displays used in wearable virtual reality and augmented reality goggles. However, the implemented technology can be challenging to implement. It must form a magnified image, focused at infinity, for imaging with the relaxed human eye, and it must be compact. The proposed work does this using coupled microlens arrays. The coupled plano-concave and plano-convex microlens arrays together act as a superlens that meets the requirements of heads-up displays. The required plano-concave and plano-convex microlens arrays are implemented using a technique of dispensing and in situ ultraviolet-curing of polymer microdroplets. It is shown that the planoconcave and plano-convex microlens arrays can be formed to enable imaging in a compact package with an excellent resolution, corresponding to a spatial modulation transfer function beyond 20 cycles/mm
