Modulation of resting human electroencephalographic dynamics by N-methyl-D-aspartate antagonist nitrous oxide
Creators: name: Foster, Brett Lucas
Publisher: name: Swinburne
Year: 2024

description: During anaesthesia electrocortical activity as observed by the human electroencephalogram (EEG) is subject to a host of quantitative changes which coincide with the selective actions of anaesthetic agents at gamma aminobutyric acid (GABA) inhibitory synapses. Through potentiation of GABAA receptor based inhibitory currents, inhaled volatile anaesthetics shift the EEG through a range of states yet to be fully understood, resulting in a large amplitude and low frequency EEG signal. Paradoxically, one class of anaesthetics/analgesics know as dissociative agents, target excitatory N-methyl-D-aspartate (NMDA) receptors, impeding their function and producing EEG patterns similar to alert and aroused states. Consequently, dissociative anaesthetics, especially the commonly used nitrous oxide (N2O) fail to be characterised by clinical EEG monitors of anaesthetic depth. To date, the effects of N2O on the EEG have yet to be adequately characterised, even though it has received extensive medical use for well over 100 years. The following investigation sought to clearly quantify the effects of N2O on the EEG in healthy male participants. It was found that during N2O inhalation the EEG underwent broadband attenuation but otherwise remained spectrally similar to resting EEG. Conversely, during the withdrawal of N2O, the EEG showed a strong rebound effect which produced large amplitude delta/theta oscillations, more typically associated with sedation and anaesthesia. The combination of these effects may help explain previously reported difficulties in attempting to monitor patient state with the EEG during anaesthesia involving N2O. Given the invariance of several standard linear measures, nonlinear analysis of the EEG was employed to investigate any higher order effects of N2O. However, a multivariate method showed nonlinearity of the EEG to be marginally altered by N2O. In general a central limiting factor was the insufficient number of participants administered higher concentrations of N2O, due to attrition. In light of previous theoretical attempts to simulate the EEG during anaesthesia, N2O is inferred to chiefly target cell populations that interact via NMDA synapses, which contribute less to the periodicity of the EEG. Contrasting this action with the standard GABAA based anaesthetics, where interacting inhibitory populations thought to be crucial in resting EEG rhythmogenesis are perturbed. These findings will assist in future attempts at monitoring dissociative anaesthesia and more generally contribute to understanding the brain dynamics associated with the NMDA receptor system.

description: In unserem Alltag begegnen und nutzen wir täglich drahtlose Funkübertragungstechnologien. Sei es beim Öffnen der Garagentür mittels Fernbedienung, beim Zugang zum Internet über WLAN oder bei der Nutzung von drahtlosen Bluetooth-Kopfhörern. In einer zunehmend drahtlosen Welt stellt sich immer wieder die Frage, wie die Vorteile dieser Technologie auch in Forschung und Entwicklung weiter genutzt werden können. Das Ziel dieser Bachelorarbeit ist die Entwicklung einer Empfängersynchronisation im ISM-Funkfrequenzband und die Evaluierung, inwieweit sich die Synchronität zwischen mehreren Empfängern durch Änderungen der Übertragungscharakteristik der verwendeten Transceiver optimieren lässt. Darüber hinaus wird die Realisierung einer Synchronisierung mittels analogen Hochfrequenzdetektoren betrachtet. Um diese Entwicklung erfolgreich durchführen zu können, wird zunächst in einem Grundlagenteil ein Überblick über die ISM-Frequenzbänder, sowie über einige relevante Aspekte der digitalen Übertragungstechnik gegeben. Im Anschluss daran wird der für diese Arbeit ausgewählte ISM-Band-Transceiver vorgestellt. Anschließend wird der Synchronisationsmechanismus, sowie der grundsätzliche Entwicklungsprozess dargestellt. Daran schließt sich der Evaluierungsteil an, in dem die verschiedenen Änderungen in der Konfiguration des Transceivers, sowie deren Einfluss auf die gemessene Synchronität zwischen den Empfängern erläutert wird. In einem zweiten Teil wird zur Signalübertragung eine analoge Detektorschaltung realisiert, die mittels eines digitalen Flankenwechsels auf das Vorhandensein von hochfrequenter Signalenergie im eingestellten Empfangskanal reagiert. Diese Arbeit zeigt, dass ein Signalübertragungssystem unter Verwendung einfacher ISM-Band-Transceiver realisiert werden kann, bei dem an mehreren Empfängersystemen beim Empfang eines Datenpakets ein Interrupt-Signal ausgelöst wird. Dieses kann dann beispielsweise genutzt werden, um einen Messvorgang an mehreren voneinander räumlich getrennten Messsystemen auszulösen. Die dabei erreichte Synchronität beträgt im Mittel 162,8 ns.

description: The mainstream theories of international relations (IR) can be categorized under two approaches: Cultural and Systems. Although the two approaches appear to be at the opposite ends of the spectrum, this paper aims to evaluate both approaches, and to provide a systemic approach to foreign policy: The systems thinking and culture (STC). STC attempts to incorporate domestic culture, a unit-level force, in analyzing states’ behavior in the international system, while still preserving the structure, as emphasized in systemic theories like neorealism. The STC model shows how the domestic culture as a unit-level force, and the structure as a systems-level force, can shape a state’s behavior and policies in the international political system.
Politicizing the Soil: A Study on Indigenous Land Rights, Activism and Art in Canada

Year: 2022

description: This paper attempts to analyse the nature of Indigenous land rights in Canada and how they survived and changed after the British Crown acquired sovereignty over the land. Though this analysis is historical it shall remain incomplete without understanding its present state and the role of the United Nations in safeguarding the rights of the Aboriginal people. This paper will elaborate on the concept of reconciliation and its various forms. The second section of this paper will thoroughly explore the incidents of the Oka Crisis. I will bring to the forefront the background information that led to the crisis, how it affected the Indigenous people and the role of contemporary media in framing the events. Lee Maracle’s novel Bobbi Lee: Indian Rebel and Beth Cuthand’s poem Post-Oka Kinda Woman will show how the Oka Crisis reassesses the conventional role of women in any kind of activism. The third section of this paper will emphasize films and visual arts that were inspired by the events at Oka. A comparative study of Alanis Obomsawin’s film Kanehsatake:270 Years of Resistance, Tracey Deer’s film BEANS, and Thomas Deer’s illustrations shall foreground the relevance of the Oka Crisis today and why it should be considered a landmark political issue in the history of Indigenous land rights movement in Canada. The paper will conclude by engaging in a discussion on the current socio-political relationship of the Indigenous people with the Canadian Government and identify the loopholes in the current governmental reconciliatoryapproach.Keywords:Films, illustrations, Indigenous Activism, Land rights, Oka Crisis, Reconciliation

description: Broadly, this thesis is a project about queerness and its relationship to Twilight. This thesis seeks to recuperate the queer in the Twilight series. Using discourse analysis, I explore both common and uncommon representations of queerness and the popular and unpopular discourses of Twilight. While both Chapter 1 and 2 offer paranoid readings of the Twilight series and its relationship to queerness, Chapter 3 presents a reparative reading of the text. I argue that Meyer’s tame and conservative vampire, conventionally represented as being either sexually ambiguous or outside the norm, is symptomatic of a modern culture that is becoming more accepting of odd, strange, and/or queer individuals. I maintain, however, that the normalization of specific "ways of being" still comes at the expense of the constitutive “other”. Furthermore, I understand this process of normalizing a monster to be representative of a seemingly apolitical, yet violent, Faludian backlash toward queers.

Projekte wie energy data-X verfolgen das Ziel,in der Energiewirtschaft neuartige Datenökosysteme zu etablieren, die den unternehmensübergreifendenDatenaustausch fördern. Energiedatenräume sollen eine Plattform schaffen,die es Marktteilnehmern ermöglicht, ihre Daten kooperativ und souverän untereinanderzu teilen. Es wird analysiert, ob die zugrundeliegende Technologie auch zum Zweck derAnlagenkommunikation in virtuellen Kraftwerken nutzbar ist und welche Konzepte Energiedatenräumemitbringen, die von Vorteil für die Direktvermarktung von erneuerbarenEnergieanlagen sind. Durch eine Expertenbefragung wurden Herausforderungen aus derPraxis identifiziert, die in das Design eines Energiedatenraums einflossen. Ein dazu entwickelterDemonstrator zeigte, dass Datenraumtechnologie den Abstimmungsbedarf zwischenAnlagenbetreibern und Vermarktern minimiert und den Prozess der Anlageneinbindung beschleunigenkann. Durch die Evaluation mit einem Direktvermarktungsunternehmen wurdeabgeschätzt, dass das befragte Unternehmen mit einem Energiedatenraum nach Vorbild desDemonstrators den jährlichen Personalaufwand für Anlageneinbindung um bis zu 82% reduzierenkönnte. Die Projektion dieser Ergebnisse auf die gesamte Branche legt nahe, dassdie Nutzung eines Energiedatenraums nicht nur vorteilhaft ist, sondern auch perspektivischdie Erschließung neuer Anlagenkategorien ermöglichen würde. Damit dies realisiert werdenkann, besteht die Notwendigkeit zur Weiterentwicklung und Anpassung der Technologie anetablierte Kommunikationsprotokolle.

Yet surprisingly, they found themselves thrust together in the media last week due to the publication of an article in the journal Nature Structural & Molecular Biology. This was the latest result of Foldit, a multiplayer online game developed by a team based at the University of Washington that cleverly uses the framework of a game for laypeople to help decipher the structures of proteins - in this case the structure of a protein known as retroviral protease that's key to the way HIV multiplies.
Evaluation of Drift Detection Techniques for Automated Machine Learning Pipelines

Year: 2021

description: Machine learning-based solutions are frequently adapted in several applications that require big data in operations. The performance of a model that is deployed into operations is subject to degradation due to unanticipated changes in the flow of input data. Hence, monitoring data drift becomes essential to maintain the model’s desired performance. Based on the conducted review of the literature on drift detection, statistical hypothesis testing enables to investigate whether incoming data is drifting from training data. Because Maximum Mean Discrepancy (MMD) and Kolmogorov-Smirnov (KS) have shown to be reliable distance measures between multivariate distributions in the literature review, both were selected from several existing techniques for experimentation. For the scope of this work, the image classification use case was experimented with using the Stream-51 dataset. Based on the results from different drift experiments, both MMD and KS showed high Area Under Curve values. However, KS exhibited faster performance than MMD with fewer false positives. Furthermore, the results showed that using the pre-trained ResNet-18 for feature extraction maintained the high performance of the experimented drift detectors. Furthermore, the results showed that the performance of the drift detectors highly depends on the sample sizes of the reference (training) data and the test data that flow into the pipeline’s monitor. Finally, the results also showed that if the test data is a mixture of drifting and non-drifting data, the performance of the drift detectors does not depend on how the drifting data are scattered with the non-drifting ones, but rather their amount in the test set

description: From the claims of punk rocker GG Allin aiming to shed his own blood for Rock ‘n’ Roll to the religiously tinted narratives of Bruce Springsteen we come to find artists using religious references to color their artistic medium. A question arises: Could these utterances and narratives show a deeper meaning behind Rock ‘n’ Roll such that it can give individuals a way to obtain religious experience? This thesis aims at arguing for the ability of Rock ‘n’ Roll as having a way to incite feelings of religious experience and communitas. Through the usage of auto-ethnography coupled with subsidiary sources from academic to pop culture writers this thesis will investigate if such a creative form helps to enable individuals to experience transcendence and feelings of community while immersed in Rock ‘n’ Roll.
The Influence of Sex on the Osmoreceptor Modulation of Heat Loss Responses

description: Females exhibit lower sudomotor response than males, which has been attributed to physiological differences between sexes. It is well accepted that non-thermal factors (i.e. baroreceptors and osmoreceptors) can influence thermoeffector responses. Even though there are sex-related differences in baroreceptor modulation of thermoeffector responses, it remains unknown if differences in osmoreceptor modulation could explain the lower sudomotor response in females. Therefore, we examined if there are sex-related differences in osmoreceptor modulation of sweating and cutaneous vascular conductance (CVC). A group of nine males and nine females were passively heated while in an isosmotic and hyperosmotic state. The onset and thermosensitivity of sweating and CVC were calculated and compared between groups and conditions. We show that the delay in onset of sweating and CVC is similar between sexes. However, thermosensitivity of sweating was lower in females than males. We conclude that hyperosmolality does not modulate the decreased sudomotor activity in females.
Design and Layout of a Transimpedance Amplifier (tia) at 50 GHz for Optical Receivers in ihp 130nm SiGe BiCMOS Technology

description: Today’s technology allows for a quick and efficient transmission of enormous amounts of data. Optical fibres are currently the most effective way to transmit enormous amounts of data. A photodiode (PD) generates current from the optical fibre’s light to receive the data transmitted. However, this current is very small. It is necessary to use an amplifier that, in addition to amplifying the photodiode current, also converts it into a voltage for the optical receiver’s subsequent phases. These amplifiers also referred to as transimpedance amplifiers, are an essential component of optical receivers because they must have a high gain to amplify the photodiode current and a large bandwidth to pick up high data rate signals. This thesis thoroughly analyses these amplifiers, outlining the advantages and disadvantages of various topologies. This thesis uses mathematical equations to describe the operation of the Transimpedance Amplifier (TIA) and to identify the optimal range between the gain, the bandwidth, and the noise (input-referred noise) to produce the amplifier with the desired characteristics. Electrical simulations were used to test all the theoretical assertions and the entire system’s behaviour for the four topologies of the common base, common emitter, regulated cascode, and darlington pair. The minimum transimpedance gain target for the TIA is 60 dBΩ with a minimum bandwidth of 40 GHz. The designed TIA should have an input-referred noise of less than 20 pA/√Hz. After thoroughly examining these four topologies, a layout is designed for darlington pair TIA with resistive feedback. The implemented TIA has achieved a transimpedance gain of 63.74 dBΩ with a broad bandwidth of 60.84 GHz. The designed TIA has achieved a low input-referred noise of 16.20 pA/√Hz. The designed TIA has a chip size of just 0.0064 mm2 and uses 30.53 mW of DC power.

description: Die Anomalieerkennung ist ein Verfahren, das vielseitig eingesetzt wird, insbesondere zur Erkennung von Ausreißern und fehlerhaften Daten. Diese bildet häufig einen Vorverarbeitungs schritt für darauffolgende Analysen. In dieser Arbeit werden Energiebedarfsdaten aus 4G- und 5G-Mobilfunknetze auf Anomalien untersucht. Dazu wird ein Datensatz mit Energiebedarfsdaten von 4-G und 5G-Basistationen mit Methoden, auf Basis von der mittlere absolute Abweichung vom Median (MAD), dem Seasonal extreme studentised Deviation Test (S-ESD), der Haar Transformation und der Heuristik orientierten Symbolic Arregation Approximation (HOT-SAX), analysiert. Vor der Anwendung der spezifischen Methoden wur den die im Datensatz enthaltenen Informationen einer visuellen Anomalieprüfung unterzogen.Dabei wurden identifizierte Anomalien sorgfältig visuell überprüft und entsprechenden Typen zugeordnet. Des Weiteren werden die Methoden auf ihre Erkennungsraten eines bestimmten Anomalietypen in den Energieverbrauchdaten untersucht. Dieser Anomalietyp wird entspre chend dem der Methode zu Grunde liegenden Verfahren bestimmt. Die Resultate ergaben, dass sämtliche angewandten Methoden erfolgreich Anomalien des beabsichtigten Typs im Energiebedarfsdatensatz identifizieren konnten. Die Evaluierung der einzelnen Methoden ergab, dass die MAD-Methode die niedrigste Erkennungsrate aufwies, während die S-ESD Methode über alle Zeitreihen hinweg prozentual die meisten Anomalien identifizierte. Diese Unterschiede in den Erkennungsraten liefern wertvolle Einblicke in die Leistungsfähigkeit der angewandten Anomalieerkennungstechniken.

description: Depression, hopelessness, and low self-esteem are implicated as vulnerability factors for suicide ideation. The association of self-esteem with suicide ideation after controlling for depressed mood and hopelessness was examined. Adult psychiatric outpatients (N = 338) completed measures of self-esteem, suicide ideation, hopelessness, and depression. Self-esteem was operationalized as beliefs about oneself (self-based self-esteem) and beliefs about how other people regard oneself (other-based self-esteem). Each dimension of self-esteem was negatively associated with suicide ideation after controlling for depression and hopelessness. Of the two dimensions of self-esteem, other-based self-esteem was the more robust predictor of suicide ideation. These findings suggest that even in the context of depression and hopelessness, low self-esteem may add to the risk for suicide ideation.
Developing as a Trainee Educational Psychologist: Establishing the Psychological Contract
Creators: name: Fox, Mark
Publisher: name: School of Psychology, University of East London
Year: 2015

description: There are two significant components of the three-year full-time doctoral programme required to train as an educational psychologist (EP) in England. These are the university-based academic component and the educational psychology (EP) service-based practice component. The purpose of this paper is to outline the ‘psychological contract’ to help understand the psychology of starting the bursary placement in the second year of the programme. Establishing the psychological contract is a concept that comes from organisational psychology to explain the dilemmas that face anyone starting a new job. Essentially it suggests that employees go through three stages of adaptation before they reach ‘nirvana’ – where there is mutual acceptance between the trainee educational psychologist (TEP) and the EP service. Strategies for moving through the three stages are outlined based on practical examples from trainees. Establishing the psychological contract is particularly relevant for understanding the psychological tasks that face a TEP starting their placement.

description: Die Anstrengungen zur Reduktion von Treibhausgasemissionen durch fossile Energieträger erfordern innovative Lösungsansätze. Neben dem Einsatz von effizienteren Energiewandlungstechnologien spielt Wasserstoff in der Planung auf nationaler Ebene eine wichtige Rolle. Er kann in einer möglichen Anwendung eingeschränkt in der bestehenden Erdgasinfrastruktur zwischengespeichert werden. In diesem Kontext können Festoxid-Brennstoffzellensysteme einen wesentlichen Beitrag leisten. Sie sind in der Lage, neben Wasserstoff auch fossile Energieträger mit einem hohen Wirkungsgrad umzusetzen. Insbesondere die Betriebsfähigkeit unter Erdgas mit schwankenden H2-Konzentrationen macht die Technologie zu einem potenziellen Baustein zukünftiger Energiesysteme. Ein störungsfreier und optimierter Anlagenbetrieb unter zeitlich fluktuierender Brenngaszusammensetzung bringt jedoch große Herausforderungen für das Regelkonzept mit sich. In der vorliegenden Arbeit wird eine vielversprechende Regelkreisarchitektur entwickelt, die ohne zusätzliche Messtechnik einen effizienten Systembetrieb selbst bei schwankender Gaszusammensetzung ermöglicht und somit einen Beitrag zur Markteinführung der Systeme leisten kann.

description: Family Euscorpiidae Laurie, 1896   Type Genus. Euscorpius Thorell, 1876.
 Synonyms.
Scorpiopidae Kraepelin, 1905 (valid as subfamily name).
 Composition. The family includes three subfamilies (Euscorpiinae, Megacorminae, Scorpiopinae) and 11 genera (Soleglad & Sissom, 2001).
 Distribution. Europe, Asia, Africa (Mediterranean Sea coast), North America, South America.
 Taxonomic history. This taxon was originally introduced as a subfamily of Chactidae. It was formally elevated to the family level by Stockwell (1992), and listed as a family in Fet & Sissom (2000a). Recently, Soleglad & Sissom (2001) conducted a detailed phylogenetic analysis of Euscorpiidae, and introduced a number of sweeping taxonomic changes. They included in Euscorpiidae the former family Scorpiopidae, transferred the genus Chactopsis from Chactidae, and introduced subfamilies and tribes. Soleglad & Sissom (2001) demonstrated the relationship of euscorpiid subfamilies as (Euscorpiinae, (Megacorminae, Scorpiopinae)).
 Biogeographic history. The euscorpiids cover a remarkable disjunct range, which includes Europe and West Asia (Euscorpiinae), South and Southeast Asia (Scorpiopini), South America (Chactopsini), and North America (Troglocormini, Megacorminae). Such a disjunction could indicate an ancient (Mesozoic?) age of Euscorpiidae, and could be explained by its Laurasian origin and subsequent differential extinction (Nenilin & Fet, 1992), with migration of Chactopsini to South America. Absence of xeric taxa is notable in this family.
 Diagnosis. See Soleglad & Sissom (2001) for details.

description: Abundance-based model evaluations with observations provide critical tests for the simulated mean state in models of intercontinental pollution transport, and under certain conditions may also offer constraints on model responses to emission changes. We compile multiyear measurements of peroxy acetyl nitrate (PAN) available from five mountaintop sites and apply them in a proof-of-concept approach that exploits an ensemble of global chemical transport models (HTAP1) to identify an observational emergent constraint. In April, when the signal from anthropogenic emissions on PAN is strongest, simulated PAN at northern midlatitude mountaintops correlates strongly with PAN source-receptor relationships (the response to 20% reductions in precursor emissions within northern midlatitude continents; hereafter, SRRs). This finding implies that PAN measurements can provide constraints on PAN SRRs by limiting the SRR range to that spanned by the subset of models simulating PAN within the observed range. In some cases, regional anthropogenic volatile organic compound (AVOC) emissions, tracers of transport from different source regions, and SRRs for ozone also correlate with PAN SRRs. Given the large observed interannual variability in the limited available datasets, establishing strong constraints will require matching meteorology in the models to the PAN measurements. Application of this evaluation approach to the chemistry-climate models used to project changes in atmospheric composition will require routine, long-term mountaintop PAN measurements to discern both the climatological SRR signal and its interannual variability. © 2018 Author(s).

Depression

description: The serotonin system, tightly controlled by negative regulation by 5-HT1A autoreceptors, is involved in MDD since manipulating different aspects of the 5-HT systems produces behavioral changes akin to MDD symptoms. Deaf1 knockout mice, which have shown increased 5-HT1A autoreceptor levels, were examined. Conversely, the effect of loss of 5-HT1A autoreceptors in adulthood was studied in 5-HT1AautoKO mice engineered for inducible knockout of the 5-HT1A autoreceptor. Anxiety and depression behavioural assays were performed on the Deaf1KO and 5-HT1AautoKO models. Deaf1KO mice displayed an overall increase in anxious behaviour, yet no change in depressive behaviour relative to controls. Conditional 5-HT1A mice displayed no changes in anxiety or depressive behaviour. Compensation from remaining aspects of the serotonin system and/or other neurological systems may account for some of the behavioural results (or lack thereof). Additional testing that includes a stress paradigm is warranted in order to reveal any stress-dependent vulnerabilities to anxiety and depression.

description: Für die Eindämmung des anthropogenen Klimawandels müssen die Treibhausgasemissionen auch im Gebäudesektor reduziert werden. Bei der Umstellung der heute fossil dominierten Wärmeerzeugung kommt Wärmepumpen eine zentrale Rolle zu. Während die Technik im Neubau inzwischen etabliert ist, bestehen Hürden für den Gebäudebestand. In bestehenden Mehrfamilienhäusern sind vergleichsweise hohe Senkentemperaturen und die Wärmequellenverfügbarkeit im urbanen Raum herausfordernd. Als Lösungsansatz der quellenseitigen Hemmnisse wird mittels modellbasierten Entwurfs der Prototyp eines Mehrquellen-Wärmepumpensystems aus Erdreich und Außenluft entwickelt. Das Ziel ist maximale Effizienz bei nachhaltiger Belastung des teillastdimensionierten Erdreichs. Hierfür wird eine fallspezifische Simulationsstudie zur Analyse der Jahresarbeitszahl und der CO2 -Vermeidungskosten bei variierenden Systemvarianten und Wärmequellendimensionen durchgeführt. Für den Proof of Concept wird ein Prototyp des Wärmepumpensystems in einem teilmodernisierten Mehrfamilienhaus aus den 1960er Jahren installiert und über den Zeitraum eines Jahres messtechnisch analysiert.

description: This study, which includes both experimental and numerical-modelling components, investigates the potentially dangerous conditions that can often occur when low-head dams (or weirs) are overtopped and ‘submerged’-type hydraulic jumps subsequently form downstream of them. The combination of high local turbulence levels, air entrainment, and strong surface currents associated with submerged jumps pose a significant risk to safety of boaters and swimmers. In this study, a wide range of flow regimes and different experimental conditions (i.e. crest length and downstream apron elevation) were considered. The experimental phase involved physical model testing to determine: (i) the hydraulic conditions that govern submerged jump formation, and (ii) the hydrodynamic characteristics of the submerged vortex. The numerical model, developed using OpenFOAM, was validated with the obtained experimental data. This research seeks to help develop improved guidelines for the design and safe operation of low-head dams. The experimental phase of the study involved physical model testing to determine: (i) the hydraulic conditions that govern submerged jump formation, and (ii) the hydrodynamic characteristics of the submerged vortex. The numerical modelling work involved using interFoam (OpenFOAM toolbox) for simulating the experimental results. InterFoam is an Eulerian 3-D solver for multiphase incompressible fluids that employs the Volume of Fluid approach (VOF) to capture the water-air interface. The developed numerical model was subsequently validated using the experimental data collected and processed by the author of this study. The range of tailwater depths associated with submerged hydraulic jump formation is dramatically reduced when a broad-crested weir is coupled with an elevated downstream apron, especially under high flow rate conditions. However sharp-crested weirs induced vortices which displayed reduced velocities and decreased spatial development, which were judged to be safer than broad crest lengths under the same discharge conditions. The classical formulation for the degree of submergence was not explicative when used to evaluate “how submerged the vortex was”. Consequently, a new normalized formulation which compares the local tailwater depth to the lower and upper tailwater limits for the submerged hydraulic jump is proposed. The numerical model developed for this study demonstrated the existence of residual turbulent kinetic energy at downstream sections located within the vortex’s extension, at instants coinciding with the presence of a fully formed roller. This turbulent energy is arguably responsible for the stationary nature of the vortex under constant flow conditions. Residual vertical and horizontal velocities at points located within the vortex’s domain are indicative of the existence of the free surface current.

description: Die Nachhaltigkeit und Transparenz von Lieferketten gewinnt aufgrund des Klimawandels, aktueller Gesetzgebungen und Lieferkettenunterbrechungen zunehmend an Bedeutung. Das Forschungsprojekt Catena-X arbeitet daher an einem unternehmensübergreifenden Datenaustausch entlang der gesamten Wertschöpfungskette mit dem Fokus auf Resilienz, Regulatorik und Nachhaltigkeit. Ziel dieser Masterarbeit, die im Rahmen von Catena-X durchgeführt wurde, ist die Erstellung eines semantischen Modells zur transparenten Nachhaltigkeitsbewertung von Lieferketten. Dieses semantische Nachhaltigkeitsmodell soll die Betrachtung unterschiedlicher Aspekte der Nachhaltigkeit ermöglichen und die Probleme der Vergleichbarkeit von Nachhaltigkeitsdaten lösen. Zudem soll das Modell externe verteilte Datenquellen integrieren, die Automatisierbarkeit von Nachhaltigkeitsbewertungen ermöglichen und die Aussagekraft sowie die Vergleichbarkeit von Nachhaltigkeitsbewertungen gegenüber existierenden Lösungen erhöhen. Im Rahmen dieser Masterarbeit wurde ein semantisches Nachhaltigkeitsmodell entwickelt, das diese Zielsetzung erfüllt. Die praktische Anwendbarkeit dieses Nachhaltigkeitsmodells konnte durch die technologische Realisierung des Supply Chain Sustainability Service (SCSS) im Rahmen von Catena-X nachgewiesen werden. Dieser Service ermöglicht die semantische Vergleichbarkeit von Nachhaltigkeitsinformationen und vereinfacht dadurch automatisierte Nachhaltigkeitsbewertungen. Das semantische Modell dieser Masterarbeit ermöglicht somit eine transparente Nachhaltigkeitsbewertung von Lieferketten, ist branchenunabhängig einsetzbar und kann nach Bedarf erweitert werden.

description: Subfamily Euscorpiinae Laurie, 1896   Type Genus. Euscorpius Thorell, 1876.
 Composition. This monotypic subfamily includes a single genus, Euscorpius (Soleglad & Sissom, 2001).
 Distribution. Europe, Asia (Turkey, Caucasus), Africa (Mediterranean Sea coast). Introduced to England, Yemen, Uruguay (Fet & Sissom, 2000a).
 Taxonomic history. For a long time, the genus Belisarius (now in Chactidae) was placed here (largely due to geographic proximity) until it was transferred to Superstitioniidae by Stockwell (1992). The genus Euscorpius includes four subgenera (Fet & Sissom, 2000a; Gantenbein et al., 1999); our ongoing revision (Fet & Soleglad, in progress) is likely to justify a genus rank for some if not all of them.
 Biogeographic history. Representatives of Euscorpius inhabit a wide variety of habitats from sea level to high mountains (over 2000 m in the Alps, Balkans and Taurus). A complex taxonomy of this genus follows its ancient history around the changing Mediterranean Sea (Birula, 1917a, 1917b) and only recently became a subject of a detailed study using rich morphological data and modern DNA techniques (Gantenbein et al., 1999, 2000, 2001b, 2002; Fet, 2003; Fet et al., 2002, 2003c; Fet & Soleglad, 2002).
 Diagnosis. See Soleglad & Sissom (2001) for details.

description: Leaflet replacement in aortic valve repair (AVr) is associated with increased long-term repair failure. Hemodynamic performance and mechanical stress levels were investigated after porcine AVr with 5 types of clinically relevant replacement materials to ascertain which material(s) would be best suited for repair. Porcine aortic roots with intact aortic valves were placed in a left-heart simulator mounted with a high-speed camera for baseline valve assessment. Then, the non-coronary leaflet was excised and replaced with autologous porcine pericardium (APP), glutaraldehyde-fixed bovine pericardial patch (BPP; Synovis™), extracellular matrix scaffold (CorMatrix™), or collagen-impregnated Dacron (HEMASHIELD™). Hemodynamic parameters were measured over a range of cardiac outputs (2.5–6.5L/min) post-repair. Material properties of the above materials along with St. Jude Medical™ Pericardial Patch with EnCapTM Technology (SJM) were determined using pressurization experiments. Finite element models of the aortic valve and root complex were then constructed to verify the hemodynamic characteristics and determine leaflet stress levels. This study demonstrates that APP and SJM have the closest profiles to normal aortic valves; therefore, use of either replacement material may be best suited. Increased stresses found in BPP, HEMASHIELD™, and CorMatrix™ groups may be associated with late repair failure.
