description: Das vorliegende Gutachten soll einen Überblick über die noch bestehenden Einsatzbereiche von Kreosot-behandelten Hölzern bieten und Kenntnis- und Entwicklungsstand über mögliche Alternativen (im chemischen Holzschutz oder mit anderen Materialien) zum Einsatz von Teeröl darlegen, um ein realistisches Bild davon zu erhalten, welche Bedeutung Kreosot in Deutschland derzeit noch hat und ob und in welchem Umfang ein Ausstieg aus Kreosot möglich ist. Hierbei werden neben Ersatzstoffen insbesondere die Verwendung anderer Materialien, aber auch andere Maßnahmen wie z.B. technische Maßnahmen zur Emissionsminderung, im Hinblick auf ihre Marktreife betrachtet. Darüber hinaus wurden Verwender des Kreosots im Holzschutz, Nutzer von mit Kreosot behandeltem Holz sowie Entwickler von alternativen Maßnahmen und Verfahren befragt. Die Ergebnisse der Recherche wurden in einem Workshop mit Vertretern der verschiedenen Bereiche diskutiert und die Ergebnisse dokumentiert. Das vorliegende Gutachten soll den im Biozidverfahren beteiligten Behörden bei der anstehenden Zulassungsentscheidung von Holzschutzmitteln auf Basis des Kreosots als Entscheidungshilfe dienen.

description: This study assesses the loyalty behaviour of consumers in fast-food restaurants in Saudi Arabia by studying the antecedents and the consequences of loyalty behaviour. The sample consisted of 231 Saudis and non-Saudis living in Saudi Arabia. They were approached using the “snowball” technique. Participants were all over the age of eighteen, and they were customers of Al-Baik restaurants. Data was collected through a face-to-face questionnaire, and analyzed using SPSS software. Specifically, Cronbach’s Alpha test, Pearson correlation coefficient, Spearman correlation coefficient, and multiple regression analysis were used. Results show that significant relationships exist between the antecedents and the consequences of loyalty behaviour. It is also indicated that participants’ personalities and values were significantly related to the loyalty behaviour of consumers in Saudi Arabia. The major limitation of this study is that it was conducted in only one city, Jeddah. Therefore, additional research should be carried out in other cities with larger samples. The research results offer compelling evidence that Saudi loyalty behaviour differs from Western behaviour. Therefore, it suggests that international fast-food operators in Saudi Arabia should take local factors into account when formulating marketing strategies, such as the role of women and youth in Saudi society. This thesis makes a novel contribution to the literature, as it is the first to model the antecedents and the consequences of loyalty behaviour of consumers in a single study. It is also the first to study contributed to the literature to examine the relation between the Six Dimensional Achievement Motivation Scale (Jackson, Ahmed, and Heapy, 1976), Rokeach Value System (1973), and loyalty behaviour of consumers.
Designing by practice: a new professional doctorate in design

description: The development of professional doctorates in Australia and elsewhere is relatively new, dating from the 1990s (Maxwell, 2003). Searches of literature that critique, guide and analyse the impact of professional doctorates have not looked at the discipline of design. This may well be as a result of the relatively new arrival on the Higher Education scene of the Professional Doctorate in Design. As with other theorists (Hoddell, Street, & Wildblood, 2002) members of the Faculty of Design, Swinburne University of Technology identified the need to focus on the practice and skills that were unique to practitioners of design. In response to this need the Professional Doctorate of Design (DDes) was accredited in 1999, the first intake of students was in 2001 and 2004 has seen the first submission for examination from the program. In this paper, we reflect on that program and position it as a catalyst for the continuing development of project-based research and the act of designing as a scholarly research methodology.
Towards Real-World Deployment of Reinforcement Learning

description: Reinforcement Learning (RL) has gained significant research interest over the past decades. However, its application to industrial problems is rare, as many studies focus on simplified problems or RL-specific benchmarks that are not directly transferable to real-world scenarios.In this thesis, we address this research gap by developing RL solutions for three concrete real-world problems. The first use case involves applying RL to control a traffic light system in Lemgo, Germany. We developed a framework, which includes a realistic simulation model and a safety layer to ensure compliance with all legal requirements. Furthermore, we integrate the safety layer more deeply into RL algorithms to achieve faster training and better performance. Additionally, we explore methods to bridge the reality gap caused by discrepancies between the simulation model and its real-world counterpart. For the second and third use cases, we developed RL-based solutions to tackle real production scheduling problems in the household appliance and automotive industries. The second use case applies RL as a constructive heuristic, meaning that the solution is built up progressively. To make the problem solvable by RL, we integrate domain knowledge using techniques such as action masking and curriculum learning. In the third case, we explore how RL can be used as an improvement heuristic, where a suboptimal initial solution is improved by RL through iterative small adjustments. Through these case studies, we demonstrate how RL can be adapted and integrated with domain knowledge to address the specific needs and constraints of real-world environments.
Part A. Sulfur ylide chemistry: Synthesis of optically active epoxides. Part B. Synthesis and characterization of 3,4-(diphenylmethyl)-1,5-dioxa-2-thiane-2-oxides.

description: Part A. Several optically active thiolanes were synthesized and converted into sulfonium salts. These were subsequently transformed into the corresponding sulfur ylides which in turn reacted with carbonyl compounds to produce optically active epoxides. trans-2,3-Diaryloxiranes have been obtained in up to 83% enantiomeric excess via the reaction of S-benzyl ylides prepared from optically active trans-2,5-disubstituted thiolanes. The complete stereofacial transfer of a benzylidene group to a substituted benzaldehyde was successfully accomplished using S-benzyl ylide derived from (1R,2S,3R,5S)-2,3-dibenzyl-1,8,8-trimethyl-3-thianiumbicyclo (3.2.1) octane perchlorate 123 (prepared from 1R,3S-(+)-camphoric acid). trans-Stilbene oxides were produced with ee's approaching enantiomeric purity. These results represent the first example of the preparation of epoxides in nearly enantiomerically pure form by a sequence which involves both a carbon-carbon and a carbon-oxygen bond rather than only carbon-oxygen bond formation. A rationale for the high chiral induction in the latter case based on the control of facial selectivity at the ylide will be discussed. The facial selectivity at the carbonyl is believed to play a minor role. The design of potentially more efficient chiral sulfide auxiliaries and their use in the synthesis of epoxide is also presented. Part B. Erythro- and threo-1,2-diphenyl-2-butylsulfinylethanol 154 and 158 were prepared from the condensation of the $\alpha$-lithio derivative of benzyl-t-butyl sulfoxide with benzaldehyde. The reaction of the erythro-isomer with sulfuryl chloride gave an unknown substance whose structure was established by X-ray difractometry as (2R$\sp*$, 3S$\sp*$, 4R$\sp*$, 6R$\sp*$)-3,4-diphenyl-6-(diphenylmethyl)-1,5-dioxa-2-thiane-2-oxide 156, the first representative of a new heterocyclic ring system. Similar treatment of the threo-isomer 158 resulted in the formation of 157, a stereoisomer of 156.

description: Recent research in ubiquitous computing has mostly concerned systems that support personal and informational issues. This paper introduces the concept of phatic technologies - systems that establish and maintain the possibility of social interactions. These systems are not concerned with capturing and communicating information as such, but with building relationships. We briefly outline our current field-based studies examining the possibilities for supporting inter-generational family interaction with technology.

description: With the goal of reducing CO2 emissions into the atmosphere and goal of total de pendent on renewable energies to supply electrical demand, high penetration of renewable energy resources with inverter technologies has significantly increased in electric power system. The high penetration of inverter based resources (IBR) in the electric grid in the past few years has created issues and challenges with respect to power system operation and grid stability. This report investigates the impacts of the high penetration of IBR on the system strength, especially the impacts of low system short circuit power and low system inertia. To mitigate these challenges, the thesis develops a security constrained unit com mitment (SCUC) model. The SCUC model includes extra security constraints for short circuit power and system inertia in order to guarantee stable and secure oper ation for the power network. The proposed SCUC simulates with alternating current (AC) power flow model with consideration of both active and reactive power, as well as maintaining volt age security and transmission capacity limits are considered. This thesis also models short circuit calculation in a mathematical programming language (AMPL) software, whose results are verified with known software (digsi lent powerfactory software). Two case studies with two test grids, four bus and fourteen bus test system respec tively, are analyzed to verify the effectiveness of the proposed SCUC model.

description: Mobile devices users are storing more and more private and often highly sensitive information on their mobiles. Protective measures to ensure that users of mobile devices are appropriately safeguarded are thus imperative to protect users. Traditional mobile login methods, like numerical or graphical passwords, are vulnerable to passive attacks. It is common for criminal s to gain access to victims' personal information by watching victims enter their passwords into their cellphone screens from a short distance away. With this in mind, a Biometric authentication algorithm based on electrocardiogram or ECG is proposed. In this system the user will only need to touch the ECG electrodes of the mobile device to gain access. With this authentication mode no one will be able to see the biometric pattern that is used to unlock the de vices. This will increase the protection for the users. The algorithm was tested with ten subjects from MCRlab at the University of Ottawa at different days and conditions using a two electrode ECG phone case. Several tests were performed in order to reach the best setting for the algorithm to work properly. The final results show that the system has a 1.41% of chance to accept false users and 81.82% of accepting the right users. The algorithm was also tested with 73 subjects from Physionet database and the results were around the same, which confirms the consistency of the algorithm. This is the first approach on mobile authentication using ECG biometric signals and shows a promising future for this technology to be used in mobiles.

description: Previous research has revealed that the experience of HIV-positive refugee women arriving from endemic countries is complicated by social, structural, and cultural issues. If and when they become pregnant, HIV-positive refugee women face a unique situation that is poorly understood by health care providers. The intersecting influences of HIV and refugee status in the context of pregnancy have been essentially unexplored in the Canadian context. The objective of this study was to describe the lived experience of pregnancy among HIV-positive refugee women; to explore the meaning of pregnancy from the perspective of HIV-positive women; and to understand the complexity of issues facing HIV-positive refugee women. An interpretive qualitative research design viewed through a critical post-colonial lens guided the study. Women were interviewed using a semi-structured in-depth approach. Four core themes emerged from the phenomenological analysis. The findings suggest that the experience of HIV and pregnancy among refugee women in Canada involves both disconnection and restoration. They must manage the dynamics of pregnancy, the impact of HIV and the cultural, political and geographic ‘newness’ of Canada. Noteworthy, are the efforts women take to conceal the HIV diagnosis. Additional insight was gained through an intersectional analysis of the data. The findings of this analysis suggest that women: 1) experienced alterations in identity 2) faced significant social disruption, and 3) are impacted by macro-level polices that influence both their initiation and access to the health care system. The lived experience of pregnancy among HIV-positive refugee women in Canada is analogous to moving through a liminal reality. HIV-positive refugee women work to restore a disrupted and “Othered” identity. Pregnancy is integral to that restoration. The results of the study have implications for nursing’s ability to support the transformative aspects of the liminal reality of pregnant HIV-positive refugee women. The potential for these transformations draw attention to nursing at practice, policy, education and research levels.
A qualitative evaluation of MEG: a group therapy program for women who binge eat

Publisher: name: Swinburne

description: The current study utilised a qualitative approach to investigate the subjective experience of six women who were part of the MEG (Moderate Eating Program) program, a group treatment program for individuals who binge eat. This study extended the Crafti (2002) quantitative study, and attempted to contribute a richer wealth of knowledge on the effectiveness of MEG in addressing the issues of its participants, and to complement the extensive body of quantitative research carried out in the field of eating disorder treatment. Participants were interviewed individually in a semi-structured format before and after completion of the program. Transcripts were analysed to find common themes. Findings from the first interview supported previous studies on bingeing antecedents and characteristics. Participants typically reported a history of family dysfunction, dieting, and adverse events, and showed evidence of sociocultural influence. In support of the existing literature, they also showed low self-esteem, overemphasis on body image and the approval of others, difficulty with assertion, difficulty with emotion regulation, social anxiety, perfectionism, and impulsivity. Hopes for treatment outcome centred around healthy control of eating, healthy body weight, healthy attitudes toward food and body, and increased awareness. Results found MEG partially successful in meeting participants’ pre-treatment goals and effecting improvements in behaviour and awareness. All participants had shown improvement to varying degrees in eating behaviours and awareness, general awareness of eating disorders, and personality/psychological factors, but improvements had been difficult to maintain after completion of the program, and most pre-treatment issues persisted. This study raised a number of possible implications for future research and treatment directions, and is best interpreted as supplementing existing knowledge of treatment for eating disorders, and providing a foundation for future studies and treatment programs to build on.

description: Long fiber reinforced thermoplastics (LFT) play an important role for accomplishing modern light weight goals. Especially the LFT-D process records a growing marked share due to its time and cost efficiency. Implementing structural applications using the LFT-D process is a main focus of the current development. Therefore, the process is adapted for the compounding of glass fiber reinforced PA6. Optimizing the extruder configuration of the LDT-D line for this specific material combination is a major challenge of the development. The goal of this work is to identify the effects of the screw configuration of the mixing extruder on the composite properties. Therefore, four different screw designs are tested. The screw configuration suggested by the LFT-D line manufacture is used as a benchmark. The other three screws are designed to increase the shear and mixing efficiency of the screw from a low to a high level. To analyse the dependency of the screw performance on the volume fill of the extruder, material is compounded using a fully filled and a particularly filled extruder. The material characterisation consists of fiber length measurements as well as tensile, flexural and impact tests. Through this analysis it is possible to show, that the fiber length plays a minor role and that a high mixing and a high shear level is required to optimize the composite’s strength. Additionally, the scattering of the material properties can be significantly reduced by a high shear and mixing level. Finally, a recommendation for the screw design is given.

description: Popular music artists portray a variety of themes through the aesthetics of their music, lyrics, and music videos. One theme in particular that began with David Bowie’s glam period (1972-1974) and the creation of his Ziggy Stardust persona is the notion of the Outsider. Bowie not only portrayed an Outsider character, but also spoke to and for those who felt like Outsiders. Punk, goth, and emo bands that were influenced by Bowie took this social stance to speak to and for their own versions of the Outsider. Drawing from subcultural theory, music analysis, and music video analysis, and using Bowie as a benchmark and influence, I explore how several other bands portray the Outsider in their music, lyrics, and music videos.

description: Family Palaeopisthacanthidae Kjellesvig-Waering, 1986 – Extinct.    Type Genus. Palaeopisthacanthus Petrunkevitch, 1913. – Extinct.
 Composition. The family includes three genera (Jeram, 1994a, 1994b, 1998; Fet, 2000e): Compsoscorpius, Cryptoscorpius, and Palaeopisthacanthus.
 Geological occurrence. Upper Carboniferous of Europe and North America.
 Taxonomic history. This family was assigned by Kjellesvig-Waering (1986) to his superfamily “ Scorpionoidea ” in a very broad sense, equivalent to the current infraorder Orthosterni. We emphatically do not include it either in our Scorpionoidea, or in any other extant superfamily or parvorder.
 Biogeographic history. Palaeopisthacanthids, the first known orthostern scorpions, inhabited a wet, humid, tropical flood-basin forest (Jeram, 2001). The European and North American Carboniferous record of Palaeopisthacanthidae has no particular biogeographic importance for further evolution of orthostern scorpions. The age of these fossils corresponds to the beginning of Pangea formation, and it was in Pangea for the next 100 Ma in Permian/Triassic that orthostern lineages evolved and dispersed, surviving as four extant parvorders.
 Diagnosis. See Kjellesvig-Waering (1986: 232) and Jeram (1994a: 523) for details on the diagnosis of this family.
 Discussion. Absence of Carboniferous orthostern fossils from southern continents is due to a much better
representation and knowledge of coal deposits in the northern continents. The exclusively preserved, rich Carboniferous fossils of Europe and North America (Jeram, 2001) include Orthosterni as well as many other scorpion lineages, which did not survive to our time. Palaeopisthacanthids are the sister group to all extant scorpions (Jeram, 1994a; Soleglad & Fet, 2001), and therefore the key taxon for rooting extant groups.

description: In aerosol science, there is an increasing interest to perform mobile measurements to obtain number size distribution of ultrafine particles (UFP), using portable instruments based on unipolar charging and size segregation by electrical particle mobility. Applications of such measurements range from ambient and indoor aerosol studies to source identification in work environments. However, knowledge on the actual measurement uncertainties of these portable instruments under various conditions has been limited. This investigation presents results from an intercomparison workshop conducted at the World Calibration Center for Aerosol Physics (WCCAP) in Leipzig, Germany, in January 2020. Manufacturers and users were invited to have their portable instruments tested and compared against reference instrumentation for particle number size distributions (PNSD) and total particle number concentration (PNC). In particular, the performances and uncertainties of the NanoScan SMPS (Scanning Mobility Particle Sizer) Model 3910 (TSI Inc.) and the Mini Wide Range Aerosol Spectrometer (WRAS) Model 1371 (Grimm Aerosol Technik) were investigated extensively against the WCCAP Mobility Particle Size Spectrometers (MPSS) and Condensation Particle Counters (CPC). A total of 11 TSI NanoScan SMPS and 4 GRIMM Mini WRAS instruments were characterized for ambient aerosols as well as lab-generated aerosols. © Author(s) 2022

description: Slender free-standing objects in a building could be excited into rigorous rocking and/or sliding motion in an earthquake. Some objects might experience overturning and hence damage when impacting on the floor. Objects which do not overturn might still experience significant damage depending on the severity and nature of the collision with the neighbouring objects and with the floor when excited into motion. This paper presents fragility curves which define the probability of overturning of objects for given object dimensions, dynamic characteristics of the building and location of the object within the building. A method for calculating the level of shock experienced by the object on pounding with the floor is also presented.

description: Das Bevölkerungswachstum sowie der von Menschen geschaffene Klimawandel bedingen einen nachhaltigen Konsum, um auch gegenwärtigen sowie zukünftigen Generationen ein Leben unter lebenswerten Bedingungen zu ermöglichen. Im Hinblick auf die Zielerreichung dieses Vorsatzes wurden von der Politik diverse Gesetze ratifiziert, welche eine Reduzierung des Konsums anstreben, ohne zunächst die Gesellschaft in ihren Gewohnheiten zu beschränken. Abhilfe schafft diesbezüglich unter anderem die Leichtbau-Produktentwicklung. Die Leichtbau-Produktentwicklung ist bereits in der heutigen Zeit integriert und wird häufig im Verkehrssektor oder der Energiewirtschaft eingebunden. Der Bedarf an leichtgewichtigen Pro-dukten führte dazu, dass diverse Leichtbau-Ansätze entwickelt wurden, die den Entwicklern als Hilfestellungen dienen, ohne konkrete Handlungsanweisungen zu nennen. Vor diesem Hinter-grund stellt die Entwicklung einer Methodik zur zielorientierten Auswahl der bereits existieren-den Leichtbau-Ansätze im jeweiligen der Schritt der Produktentwicklung das übergeordnete Ziel der Arbeit dar. Infolgedessen werden im Rahmen dieser Arbeit allgemeine Anforderungen an die Leichtbau-Produktentwicklung vorgestellt sowie die etablierten Leichtbau-Ansätze in einen generischen Produktentwicklungsprozess integriert. Anschließend erfolgt zunächst eine Analyse der Korrelatio-nen zwischen den Anforderungen sowie den Leichtbau-Ansätzen, welche durch eine Experten-umfrage verifiziert wird. Basierend auf den Ergebnissen können daraufhin die Anforderungen entsprechend der Zielsetzung gewichtet und mittels eines QFD ähnlichen Ansatzes aus geeigneten Leichtbau-Ansätzen gewählt werden. Die Methodik wird an zwei unterschiedlichen Konzepten von Fahrradanhängern geprüft, wodurch nachhaltige sowie leichtgewichtige Lösungsansätze identifiziert werden, welche die Anwendbarkeit und sowie das Potential belegen. Mithilfe der Methodik werden Konstrukteure sys-tematisch angeleitet, anstatt zufällige Lösungen zu finden. Die aufgezeigten Kombinationen von Leichtbau-Ansätzen fördern zudem die Erkennung alternativer sowie innovativer Lösungsansätze, bei gleichzeitig geringerem Zeitaufwand.

description: With the speed of change exacerbated by technological innovation, shifting political and economic structures as a result of globalization, and the currently unchecked climate crises, discourses and practices surrounding how we conceptualize the future must change. This is also true for how curriculum is designed to address the future, and inform what young people learn in school about, and in preparation for, an increasingly uncertain future. Problematizing the neoliberal approach many curricular orientations have to the future through the emphasis on individual progress, control, and skills geared towards 21st century work, in this paper I frame science fiction and speculative storytelling modes as an important intervention in this area. Drawing from a collaborative world building project in a secondary English classroom in which students used world building to imagine the future together, I explore the important way speculative storytelling can frame new ways of teaching about, and towards, uncertain futures.

description: Here we report our perspective on applying GapmeR technology in combination with recombinant angiotensin-converting enzyme 2 (ACE2) in the treatment of COVID-19 patients. GapmeR is a cell-permeating antisense single-stranded DNA molecule that can be designed to specifically target intracellular severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Once internalized into host cells, such as lung alveolar cells, GapmeR molecules can bind to the viral RNA. This RNA/DNA hybrid will then be degraded by the RNase H enzyme abundantly present in the host cells. GapmeRs can be delivered to COVID-19 patients through inhalation or via nebulization. SARS-CoV-2- targeted GapmeR can also be given to frontline healthcare workers as a prophylactic protection. The recombinant ACE2 protein, the efficacy of which is being evaluated in clinical trials, will bind to the spike (S) glycoprotein of extracellular SARS-CoV-2 and potentially block viral infectivity. We propose that combining inhalable SARSCoV-2-targeted GapmeRs with recombinant ACE2 could provide a viable and rapidly implementable more effective therapeutic approach for eradicating SARS-CoV-2 and save millions of lives.

description: Terahertz (THz) technology is revolutionizing non-destructive testing, enabling safer and more efficient quality control in industrial production. Unlike X-rays, THz radiation is non-ionizing, making it ideal for inspecting products throughout the production chain. However, THz technology remains underutilized due to limited detection methods. In this dissertation, nonlinear upconversion is used to transfer the THz measurement information to the optical range, facilitating easier and more cost-effective detection. A novel setup for the nonlinear detection of THz radiation using picosecond pulsed optical and THz radiation is presented, which utilizes different nonlinear optical media for upconversion of THz radiation, achieving a high dynamic range and signal-to-noise ratio. The initial setup enables THz time-of-flight measurements and has been tested on materials like printing paper and silicon wafers. Further enhancements allow phase measurements and reduce data acquisition time, with applications demonstrated in spectroscopy and thickness measurement. The resulting system shows a competitive alternative to established THz measurement methods.

description: This thesis describes the development and validation of a look-up table capable of predicting heat transfer to water flowing vertically upward in a circular tube in the trans-critical pressure range from 19 to 30 MPa. The table was based on an extensive and screened experimental database and its trends were smoothened to remove unrealistic scatter and physically implausible discontinuities. When compared to other prediction methods, the present look-up table approximated the experimental data closer in values and trends. Moreover, unlike existing prediction methods, the table applies not only to normal heat transfer conditions but also to conditions with heat transfer deterioration and enhancement. A separate multi-fluid look-up table for trans-critical heat transfer was also developed, which besides the existing water database incorporated new measurements in carbon dioxide; the latter were collected at the University of Ottawa supercritical flow loop under conditions of interest for the current Super-Critical Water-Cooled Reactor designs, for which few water data were available in the literature. Existing fluid-to-fluid scaling laws were tested and two additional sets of scaling laws were proposed, which are applicable not only to the supercritical pressure region, but also to the high pressure subcritical region. The multi-fluid table is applicable to water at conditions of normal and abnormal heat transfer, but its applicability to model fluids is restricted to the normal heat transfer mode.
Currere at the Cross-Roads: The Deeply Theological in the Age of Covid-19

description: This paper is about the possibility of educating teachers to become more deeply theological. Here, the author draws upon literature in both theological studies and currculum studies. Moreover, the author draws upon on the ground experience as a trauma chaplain in a large hospital and experience as a university professor in a large university. There are many similarities between the work of the hospital chaplain and the work of the university professor. Although religious studies has been dealt with in the past in the field of curriculum studies, little or no work has been done on comparing chaplaincy to the work of teaching.

description: Amphibians develop in aquatic environments where they are very susceptible to the effects of pesticides and other environmental contaminants. Glyphosate-based herbicides are widely used and have been shown to affect survival and development of tadpoles under laboratory conditions. The goal my thesis is to determine if agriculturally relevant exposure to Roundup WeatherMax®, a herbicide formulation containing the potassium salt of glyphosate and an undisclosed surfactant, influences the survival and development of wood frogs tadpoles (Lithobates sylvaticus) under both laboratory and field conditions. In the field, experimental wetlands were divided in half using an impermeable curtain so that each wetland contained a treatment and control side. Tadpoles were exposed to two pulses of this herbicide at environmentally realistic concentration (ERC, 0.21 mg acid equivalent (a.e.)/L) and predicted environmental concentrations (PEC, 2.89 mg a.e./L), after which survival, growth, development, and expression of genes involved in metamorphosis were measured. Results indicate that exposure to the PEC is extremely toxic to tadpoles under laboratory conditions but not under field conditions. Results from both experimental conditions show sublethal effects on growth and development, and demonstrate that ERC of glyphosate-based herbicides have the potential to alter hormonal responses during metamorphosis. My secondary objectives were to compare the effects of Roundup WeatherMax® to the well-studied Vision® formulation (containing the isopropylamine (IPA) salt of glyphosate and POEA), and to determine which ingredient(s) are responsible for the sublethal effects on development. Survival, growth and gene expression results indicate that Roundup WeatherMax® has greater toxicity than Vision® formulation. Contrary to my prediction, results suggest that, under realistic exposure scenarios, POEA is not the sole ingredient responsible for the observed developmental effects. However, my results demonstrate that chronic exposure to the POEA surfactant at the PEC (1.43 mg/L) is extremely toxic to wood frog tadpoles in laboratory. As part of the Long-term Experimental Wetlands Area (LEWA) project, this research contributes to overall knowledge of the impacts of glyphosate-based herbicides on aquatic communities.
In my time of dying: the premature death of a film classic
Creators: name: Tofts, Darren

description: 'The Song Remains the Same' premiered on the 19th October 1976 at Cinema 1 in New York City. Adorning the walls of the cinema’s foyer was the cover art of the double soundtrack album that accompanied the film that very quickly went Platinum. It features a chicly run-down picture theatre that resonates with homely echoes of small town movie houses, vestigial monuments of a nostalgic past of shared social experience. But the nostalgia for the decrepit building and what it once represented is bittersweet, as in the elegiac conclusion of Peter Bogdanovich’s 'The Last Picture Show' (1971). Unknown to the band and its legions of followers throughout the world, that image of ramshackled former glory suggested, in advance, how Led Zeppelin would be judged and how mercilessly run down the film would be by both fans and critics alike. Negativity towards the film characterised virtually every moment of its making, an atmosphere of bad vibes generated from within the inner circle of the band and its management and the two hapless directors, Joe Massot and Peter Clifton, who attempted to exercise their craft and at the same time appease the hammer of the gods. In retrospect, it is no surprise why it was subject to such vicious critical scrutiny. Generically, the film sits awkwardly between a rockumentary that details the highs and lows of being on tour and a live concert experience of the biggest rock band in the world at the time, captured on stage at Madison Square Garden in New York (the film was promoted as a ’front row seat on Led Zeppelin’). Uneasily woven into this mix of the more familiar attributes of the rock film genre was a series of autobiographical, highly stylised fantasy sequences, of the kind noted previously, designed to explore the personalities and imaginations of the band members themselves. But, unlike previous films that documented famous rock musicians at work (such as The Beatles in Michael Lindsay-Hogg’s 'Let It Be' [1970] and The Rolling Stones in Jean-Luc Godard’s 'Sympathy for the Devil' [1968]), 'The Song Remains the Same' sought to portray the band ‘in concert and beyond‘, transforming the four musicians and their manager into larger than life characters, roguish scoundrels straight out of the picaresque tradition.
Development of a Symbolic Computer Algebra Toolbox for 2D Fourier Transforms in Polar Coordinates

description: The Fourier transform is one of the most useful tools in science and engineering and can be expanded to multi-dimensions and curvilinear coordinates. Multidimensional Fourier transforms are widely used in image processing, tomographic reconstructions and in fact any application that requires a multidimensional convolution. By examining a function in the frequency domain, additional information and insights may be obtained. In this thesis, the development of a symbolic computer algebra toolbox to compute two dimensional Fourier transforms in polar coordinates is discussed. Among the many operations implemented in this toolbox are different types of convolutions and procedures that allow for managing the toolbox effectively. The implementation of the two dimensional Fourier transform in polar coordinates within the toolbox is shown to be a combination of two significantly simpler transforms. The toolbox is also tested throughout the thesis to verify its capabilities.

description: Terahertz technology is a promising solution in the field of nondestructive testing, imaging, and sensing. At this spectrum the radiation can penetrate a wide variety of non-conductive materials while remaining non-ionizing and safe for biological tissues. In this work, transceiver units based on the FMCW radar concept operating in terahertz frequencies are integrated with optomechanical components to construct a compact mobile terahertz scanner for 3D imaging. To achieve a tunable and extremely broadband terahertz FMCW radar, photomixing phenomena is used for terahertz generation and detection. The high-resolution 3D imaging capabilities of the optoelectronic terahertz FMCW radar and its wide-reaching applications in various domains are investigated and validated here. Moreover, a novel application for material characterization is studied, namely the thickness measurement of electrode films of battery cells used in battery electric and hybrid vehicles (BEV and EHV). By incorporating an aspherical telecentric f-theta lens into the photonic FMCW radar system, this work focuses further on precise and consistent imaging performance across a scanning area with a large field of view.
