description: Significant efforts have been made in the last decades to decrease the world’s dependency to fossil fuels. One of the fronts which has shown major improvement is gas turbine efficiency. To this end, components such as recuperators have been developed to recover heat that is usually trapped and wasted in the exhaust gases of combustion processes. Brayton Energy Canada has recently developed a promising compact heat exchanger that could be used as a recuperator in gas turbines. Nevertheless, this novel type of wire mesh heat exchanger still has room for improvement, especially regarding the way that its fin arrays are manufactured due to the fact that the technique presently used is time consuming and consequently costly. The present research aims to manufacture near-net shaped pin fin arrays using cold gas dynamic spray as an additive manufacturing technique by selectively covering the substrate by the means of a mask. Moreover, this research work studies the feasibility of using CGDS as an additive manufacturing technique to produce pin fin arrays, the thermal and hydrodynamic performances of this new type of pin fin created, the effect of geometric parameters such as fin density and height on the performances, the viability of the sprayed pin fins in a real environment by means of finding mechanical properties such as adhesion strength, the possibility of producing a streamwise material anisotropic fin arrays, and finally the different adhesion mechanisms by means of numerical modeling of the relevant impact physics.

description: Canada’s aging population is expected to have an impact on all public institutions; for public libraries, the emergence of a large, multi-generational user group of older adults challenges the current paradigm of services to seniors. This thesis examines a subset of this user group: baby boomer library patrons who are in a caring relationship with elders. It investigates how these patrons interact with the public library both for themselves, and as carers, in order to reveal library-related issues particular to this growing segment of the population. The study takes place within a conceptual framework derived from the ethic of care, and from emerging theories of library-as-place rooted in the fields of human geography and sociology. Using a qualitative instrumental case study method, long form interviews were conducted with respondents recruited through theoretical sampling extended by snowball sampling. While not generalizable, findings suggest that while these baby boomer respondents value their libraries deeply, there is potential to create services and practices more attuned to the needs of older adults who are in relationships with elders.

description: Southeast Asian rivers convey large amounts of organic carbon, but little is known about the fate of this terrestrial material in estuaries. Although Southeast Asia is, by area, considered a hotspot of estuarine carbon dioxide (CO2) emissions, studies in this region are very scarce. We measured dissolved and particulate organic carbon, as well as CO2 partial pressures and carbon monoxide (CO) concentrations in two tropical estuaries in Sarawak, Malaysia, whose coastal area is covered by carbon-rich peatlands. We surveyed the estuaries of the rivers Lupar and Saribas during the wet and dry season, respectively. Carbon-to-nitrogen ratios suggest that dissolved organic matter (DOM) is largely of terrestrial origin. We found evidence that a large fraction of this carbon is respired. The median pCO2 in the estuaries ranged between 640 and 5065 μatm with little seasonal variation. CO2 fluxes were determined with a floating chamber and estimated to amount to 14-268 mol m-2 yr-1, which is high compared to other studies from tropical and subtropical sites. Estimates derived from a merely wind-driven turbulent diffusivity model were considerably lower, indicating that these models might be inappropriate in estuaries, where tidal currents and river discharge make an important contribution to the turbulence driving water-air gas exchange. Although an observed diurnal variability of CO concentrations suggested that CO was photochemically produced, the overall concentrations and fluxes were relatively moderate (0.4-1.3 nmol L-1 and 0.7-1.8 mmol m-2 yr-1) if compared to published data for oceanic or upwelling systems. We attributed this to the large amounts of suspended matter (4-5004 mg L-1), limiting the light penetration depth and thereby inhibiting CO photoproduction. We concluded that estuaries in this region function as an efficient filter for terrestrial organic carbon and release large amounts of CO2 to the atmosphere. The Lupar and Saribas rivers deliver 0.3 ± 0.2 Tg C yr-1 to the South China Sea as organic carbon and their mid-estuaries release approximately 0.4 ± 0.2 Tg C yr-1 into the atmosphere as CO2.

description: Genomic analyses revealed Prospect Hill-1 (PH) virus has three RNA segments Large (L), Medium (M) and Small (S), like all Bunyaviridae, with relative molecular masses (M$\sb{\rm r}$) of 2.2 $\times$ 10$\sp6,$ 1.3 $\times$ 10$\sp6$ and 0.6 $\times$ 10$\sp6$ respectively. Complementary DNA representing the genomic M RNA segment of the PH virus was cloned and its nucleotide sequence determined. As with other Bunyaviridae the 3$\sp\prime$ and 5$\sp\prime$ termini are inversely complementary and could possibly allow the M RNA segment to form a circular structure. The PH virus M RNA segment has a single long open reading frame (ORF) in the viral complementary-sense RNA. This protein is the putative glycoprotein precursor that would be cleaved into the two viral envelope glycoproteins G1 and G2. The predicted gene product of the PH virus M segment was compared with the corresponding gene products of Hantaan virus, Sapporo rat virus strain SR-11 (SR) virus and Hallnas virus. There was 74% and 79% amino acid sequence similarity between the G1 and G2 proteins of PH virus and Hallnas virus respectively. In contrast, there was only 50% amino acid sequence similarity between the G1 proteins of PH virus and SR virus or Hantaan virus. However, the G2 proteins of SR virus and Hantaan virus were more closely related to the G2 protein of PH virus with amino acid sequence similarity of approximately 62%. Hydrophilicity plots of the four virus glycoproteins were very similar. The region of greatest hydrophilicity was conserved in the Hallnas virus, SR virus and Hantaan virus, and was located near the C-terminus of the G1 protein. In contrast, the region of greatest hydrophilicity in the PH virus glycoprotein precursor was located closer to the N-terminus of the G1 protein. Our data demonstrate that despite differences in the serotypic profiles and virulence of PH virus and Hallnas virus, their G1 and G2 proteins are closely related. Our data demonstrate that despite differences in the serotypic profiles and virulence of PH virus and Hallnas virus, their G1, G2 and N proteins are closely related. We conclude that PH virus and Hallnas virus may have evolved along a separate evolutionary pathway in the Hantavirus genus from SR virus and Hantaan virus. (Abstract shortened by UMI.)

description: A man who was arguably the most influential educator of the last 50 years - though he was not widely known to the American public - died on July 31. A respected mathematician and early pioneer of artificial intelligence, Seymour Papert was 88. His career presaged much of today's focus on education in science, technology, engineering and mathematics, and helped shape the classroom of today and of the future. As an academic, he paved the way for generations of researchers. In their 1969 book 'Perceptrons,' Papert and his MIT colleague Marvin Minsky were early advocates of the need to investigate the computational details of how early artificial intelligence actually functioned. Today that approach underpins evaluations of neural networks, which foster deep learning, a computational technique widely used in data analytics. But perhaps his most powerful legacy sprang from his research into learning, specifically the role of computers in education. Papert argued that learning was most successful when students were engaged in creative acts - when they were making things. For him, computers allowed and encouraged creation in a broad range of areas, and could therefore be a key to unlocking better teaching and learning.

description: Since the introduction of helmets the incidence of traumatic brain injuries (TBI) in ice hockey has greatly decreased, but the incidence of concussions has essentially remained unchanged. Despite goaltenders in ice hockey being the only players on the ice for the entire game, few have assessed the performance of ice hockey goaltender masks. In ice hockey, goaltenders are exposed to impacts from collisions, falls and projectiles. The objective of this study was to assess the protective capacity of ice hockey goaltender masks for three accident events associated with concussion. A helmeted and unhelmeted medium NOCSAE headform were tested under conditions representing three common accident events in ice hockey. Falls were reconstructed using a monorail drop. A pneumatic linear impactor was used to reconstruct collisions and projectile impacts were reconstructed using a pneumatic puck launcher. Three impact locations and three velocities were selected for each accident event based on video analysis of real world concussive events. Peak resultant linear acceleration, peak resultant rotational acceleration and rotational velocity of the headform were measured. The University College Dublin Brain Trauma Model (UCDBTM) was used to calculate maximum principal strain (MPS) and von Mises stress in the cerebrum. The results demonstrated the importance of assessing the protective capacity of ice hockey goaltenders masks for each accident, as each event created a unique response. A comparison of unhelmeted and helmeted impacts revealed ice hockey goaltender masks are effective at reducing the risk of both concussion and TBI for falls and projectiles, but less so for collisions. Further, the risk of more serious injuries was found to increase for falls and collisions as impact velocity increased. The results highlight the importance of impacting multiple locations when assessing the protective capacity of ice hockey goaltenders masks, as different impact locations result in unique responses. Overall this study demonstrated ice hockey goaltenders masks capacity to reduce the risk of concussion across three accident events.

Effective masking levels for bone-conduction auditory brainstem response stimuli in infants and adults with normal hearing
Creators: name: Lau, Ricky

Publisher: name: The University of British Columbia
Year: 2021

description: Objective: The purpose of the present study was to investigate effective masking levels (EMLs) for bone-conduction auditory brainstem response (ABR) testing in infants and adults. Early hearing detection and intervention programs aim to limit delays in identifying ear-specific type/degree of hearing loss in infants using the ABR. Ear-specific assessment poses challenges as sound delivered to one ear can travel across the skull and activate the contralateral cochlea. Wave V amplitude and latency measures ipsilateral and contralateral to the bone oscillator can be compared to isolate the test cochlea in some cases; however, when these findings are equivocal, clinical masking is required. This study aims to determine EMLs for ABRs elicited to 500- and 2000-Hz BC stimuli for normal-hearing infants (0-18 months) and adults. Design: Participants were 21 adults (18-54 years) and 24 infants (5-47 weeks) with normal hearing. BC 500- and 2000-Hz brief tonal stimuli at intensities approximating normal levels were presented via a B-71 oscillator (Infants: 20 dB nHL at 500 Hz and 30 dB nHL at 2000 Hz; Adults: 500 and 2000 Hz at 20 and 30 dB nHL). White-noise masking was presented binaurally via ER-3A earphones (22-82 dB SPL; 10-dB steps). The lowest level of masking to eliminate a BC response was deemed the EML. Results: For stimuli presented at 20 dB nHL, adult mean (1SD) EMLs for 500 and 2000 Hz were 65(9) and 53(6) dB SPL, respectively. Mean EMLs for infants were 80(6) dB SPL for 500 Hz at 20 dB nHL and 64(9) dB SPL for 2000 Hz at 30 dB nHL. Compared to adults, infants required approximately 13 dB more masking at 500 Hz but a similar amount of masking at 2000 Hz. Infants required 26 dB more masking at 500 versus 2000 Hz, whereas, adults required only 12 dB more masking. Conclusions: Maximum binaural effective masking levels for infant BC responses elicited to 500 Hz at 20 dB nHL are 82 dB SPL, and for 2000 Hz at 30 and 40 dB nHL, respectively, are 72 and 82 dB SPL. Monaural masking levels for the non-test ear (assuming 10 dB of interaural attenuation) recommended clinically are as follows: (i) 500 Hz: 72 and 82 dB SPL at 20 and 30 dB nHL, respectively; and (ii) 2000 Hz: 62, 72 and 82 dB SPL at 30, 40 and 50 dB nHL, respectively. Unsafe levels of white noise would be needed to effectively mask at greater stimulus levels.

description: Finding a suitable parking space in busy cities is a time consuming and challenging task. During the searching process, drivers become frustrated and distracted. Motor vehicle drivers might not initially find a free spot, and will leave the area by making a loop to find another spot close to their destination. As a result, there is increased congestion on the road, sometimes causing accidents, and wasting valuable time. To address this problem, we believe that a parking reservation system is necessary and will help reduce the high volume of congestion that might otherwise lead to accidents and have many other environmental and health impacts. The objective of our research is to propose a mobile-based reservation system. The process of finding a free parking space shall be made easy and fast; customers will only be a few taps away from guaranteed and paid parking, based on their preferences. The model presented considers all nearby parking service providers’ ability to satisfy customers’ requirements and will reserve the best parking for the user.

description: Drop-on-Demand (DoD) printing is a marking solution that prints individual droplets of ink onto the substrate. In combination with ink formulas which contain solid glass and ceramic particles, DoD printing can be used to print Unique Identifiers onto metal substrates. The marking is not only suitable for harsh process environments such as temperatures above 1000°C, but also more stable and faster to apply, e.g., compared to laser marking. This work investigates a predictive maintenance concept which is based on monitoring of the printing quality through Computer Vision based analysis of the printed pattern. Typical indicators for printing quality degradation are identified and are made quantifiable through segmentation of the individual ink drops and analysis of drop-specific parameters. The most meaningful parameter for the quality degradation is the deviation of ink droplets from their target position caused by odd trajectories, therefore different target position algorithms are explored. Quality measures are evaluated for series of printed results, showing the suitability of the measurands for monitoring printing quality and predicting the remaining useful lifetime.

description: In October 1869, the fledgling Canadian federation was preparing for the transfer of Rupert's Land and the Northwestern Territory when the Métis set up a Provisional Government in order to resist what they saw as a unilateral annexation of their homeland. Although there were multiple references made to 'republicanism' during the Resistance, no scholar has ever explored whether republican conventions were actually present in political discourse in the District of Assiniboia prior to the Resistance and whether they were effectively activated during the Resistance. Working from the Cambridge School approach of discourse analysis, this thesis first identifies the conventions of democratic rhetorical republicanism, which includes positive and negative liberty, the rule of law, the mixed and balanced constitution and citizenship, which in turn involves virtue, the militia and real property. It then looks at the gradual introduction in Assiniboia of republican discourse from multiple sources, including the United States, Lower Canada, Upper Canada, Ireland, France and Great Britain and its circulation throughout several practical political struggles during the period from 1835 to 1869. In doing so, it shows that certain 'organic intellectuals' acted as 'transmission belts' of republican conventions and that institutional structures were a factor that rendered the activation of such conventions almost inevitable. By the time the Resistance took place in 1869, a more or less fully developed republican paradigm formed part of the linguistic matrix and was available to political actors in Assiniboia. Finally, the thesis shows that republican discourse was effectively mobilised by identifying fragments of republican conventions that were harnessed in various speechacts during the Resistance. It is argued that republican language was fundamental to the success of the ideological and political manoeuvres of the leaders of the Resistance as it was particularly effective both as an instrument of anti-colonialism and as a pragmatic ideal of self-government that sought to correct the iniquities of colonial government.

description: The overlay and stitching error effects in the boundary area between the adjacent ablated volumes of the polycarbonate (PC) substrate under 248 nm KrF excimer pulsed radiation have been studied. We have investigated the effects of different overlay errors on the surface roughness, and categorized these to five different cases. The effect of increasing the number of laser shots (25 to 500) has been examined with a fluence of 1.1 J/cm2. The results of our analysis using Scanning Electron Microscopy (SEM), Laser Scanning Confocal Microscopy (LSCM) and optical microscopy are presented. We find that by applying the different strategies we can successfully reduce the error by 80 %. This paper also presents the strategies and a software system to control these micromachining parameters.

description: Le but principal de la thèse est de mettre en lumière une conceptualisation heuristique de l’incertitude qui permette d’expliquer la manière dont elle est interprétée par les citoyens dans le contexte des risques de santé publique et quelles stratégies de gestion (coping) sont déployées afin d’y faire face. L’emploi de méthodes mixtes est privilégié. La première étude, testant un schème psychométrique sur les données d’une enquête nationale documentant le risque et l’acceptabilité perçue d’un enjeu de santé publique (N= 1517), révèle que l’incertitude perçue se distingue d’autres évaluations cognitives de la menace, telle que la probabilité. Elle est associée à une augmentation de l’inquiétude ressentie seulement lorsque l’impact perçu du risque sur la santé est élevé. La deuxième étude, testant un devis de recherche expérimental auprès de Canadiens du grand public (N= 434), démontre que l’effet sur l’adhérence au message, de différents types d’avertissements à propos d’un risque varie selon les sources d’incertitude communiquées. En particulier, la communication d’ambiguïté (divergence entre experts ou données contradictoires) diminue l’adhérence au message, alors que la communication d’incertitude épistémique (manque de données scientifiques) ne diminue pas l’adhérence au message ni la confiance envers la source. Les dernières études explorent la construction du sens donné à l’incertitude par les citoyens à travers une approche qualitative, avec trois entrevues individuelles et neuf groupes de discussion réalisés auprès d’adultes provenant de villes canadiennes (N= 47). La troisième étude analyse la portion des entrevues mettant l’accent sur les attentes des citoyens à propos de qui devraient être impliqués dans la communication gouvernementale du risque, pourquoi les incertitudes devraient être communiquées, lesquelles sont désirables, et comment et quand les discuter. La quatrième étude emprunte la méthode de la théorie ancrée afin d’élaborer un schéma conceptuel explicatif des réactions à l’incertitude. Celui-ci identifie et met en lien les principaux facteurs d’importance, soit: la source d’incertitude, les caractéristiques situationnelles et individuelles, le contrôle perçu et la confiance envers la source d’information et les gestionnaires du risque. Ces résultats permettent de mieux comprendre et d’anticiper les réactions du public dans la communication et la gestion du risque.

description: In this dissertation, high throughput approaches for diffusion and oxidation processes for silicon solar cell manufacturing are investigated. The focus lies on developing sustainable processes or process combinations for PERC and TOPCon solar cells which enable higher throughputs and reduced energy consumption than state-of-the-art processes at comparable energy conversion efficiency level. High throughput is reached by increasing the wafer load in the process using wafer stacks, where the wafer surfaces are touching each other. The interactions between phosphorus diffusion and thermal oxidation of the stack process approach are examined in detail. Further, a hypothesis for the oxygen gas transport mechanism into the wafer gap is stated and confirmed by experiments and simulation. Further understanding of the stack diffusion approach is generated when investigating boron-doping processes.

description: The purpose of this doctoral dissertation was to examine how high school sport can be framed as a context that facilitates positive youth development. Data were collected in two phases. In phase one, a case study of a high school ice hockey program recognised for focusing on youth development was conducted. One article was written, documenting the design of the program and its impact on student development. Results indicate that participants believed students were learning a wide range of life skills and values but that administrators and coaches faced many challenges in sustaining the program. In phase two, interviews were conducted with model high school coaches and their athletes and three articles were written (articles two, three, and four). The second article examines how model high school coaches teach students life skills and how to transfer these skills to other life domains. Results demonstrate that the model coaches prioritised development and had specifically designed strategies to help students learn and transfer life skills. The third article investigates how model high school coaches learn to facilitate positive youth development through sport. Results indicate that these coaches were lifelong learners who took advantage of learning situations in order to refine their skills and use sport as a tool for development. The fourth article examines the characteristics athletes prefer in high school coaches. Results indicate that most athletes prefer coaches who are supportive, knowledgeable, good motivators, and prioritise athlete development. Based on the results of the two phases of data collection, an article was written with the objective of providing coaches with strategies on how to facilitate positive youth development through sport. Strategies consist of: (a) developing a coaching philosophy, (b) developing relationships with athletes, (c) having developmental strategies, (d) making athletes practice life skills, and (e) teaching athletes about the transferability of life skills.

description: This study is a mixed methods investigation, based on a case study of The Ottawa Hospital’s recent and ongoing implementation of an integrated performance management system (IPMS). It is the first empirical investigation to identify the reasons why Canadian healthcare leaders choose to implement an IPMS in a hospital setting, the core components of hospital-based IPMSs, the challenges that senior leaders face when implementing such systems, and how these challenges might be mitigated to increase the likelihood of a successful implementation. Key findings include the need for senior leaders to carefully consider organizational culture prior to fully implementing an IPMS, engaging physicians early in the journey, and coordinating the implementation so that knowledge, skill, and expertise, as it relates to the IPMS, are distributed across the organization in tightly knit waves. Recommendations for future research include the development of frameworks for the design, implementation, and use of IPMSs

description: The document presents the extended research work on the case study of Republic of Serbia in the frame of GreenFORCE Project WP 4 deliverables. The research Case is titled: From conventional to green - key elements for development of the city of Kragujevac sustainable mobility strategy

The research aims to develop scenarios through detailed analysis and surveys to optimize the use of public transportation, with a focus on decreasing private vehicle use in city centers and minimizing pollution through the integration of electric vehicles. The preliminary concept proposes a two-tier transport system where passengers initially travel using conventional buses to reach the peripheries of the central urban area. From these transit points, passengers would switch to electric buses. These electric buses would operate at frequent intervals, efficiently distributing passengers throughout the central area to their final destinations. This model not only aims to reduce the urban carbon footprint by limiting the number of petrol and diesel vehicles in densely populated areas but also enhances the accessibility and convenience of public transport, potentially increasing its usage among the city's residents and visitors. The strategic deployment of electric buses is intended to provide a seamless, eco-friendly, and efficient transportation solution that aligns with broader environmental and urban planning goals.

description: Critical data selection is essential for determining representative baseline levels of atmospheric trace gases even at remote measurement sites. Different data selection techniques have been used around the world, which could potentially lead to reduced compatibility when comparing data from different stations. This paper presents a novel statistical data selection method named adaptive diurnal minimum variation selection (ADVS) based on CO2 diurnal patterns typically occurring at elevated mountain stations. Its capability and applicability were studied on records of atmospheric CO2 observations at six Global Atmosphere Watch stations in Europe, namely, Zugspitze-Schneefernerhaus (Germany), Sonnblick (Austria), Jungfraujoch (Switzerland), Izanã (Spain), Schauinsland (Germany), and Hohenpeissenberg (Germany). Three other frequently applied statistical data selection methods were included for comparison. Among the studied methods, our ADVS method resulted in a lower fraction of data selected as a baseline with lower maxima during winter and higher minima during summer in the selected data. The measured time series were analyzed for long-term trends and seasonality by a seasonal-trend decomposition technique. In contrast to unselected data, mean annual growth rates of all selected datasets were not significantly different among the sites, except for the data recorded at Schauinsland. However, clear differences were found in the annual amplitudes as well as the seasonal time structure. Based on a pairwise analysis of correlations between stations on the seasonal-trend decomposed components by statistical data selection, we conclude that the baseline identified by the ADVS method is a better representation of lower free tropospheric (LFT) conditions than baselines identified by the other methods. © Author(s) 2018.

description: As the lung develops, epithelial-mesenchymal crosstalk is essential for the developmental processes that drive cell proliferation, differentiation, and extracellular matrix (ECM) production within the lung epithelial-mesenchymal trophic unit (EMTU). In asthma, a number of the lung EMTU developmental signals have been associated with airway inflammation and remodeling, which has led to the hypothesis that aberrant activation of the asthmatic EMTU may lead to disease pathogenesis. Monoculture studies have aided in the understanding of the altered phenotype of airway epithelial and mesenchymal cells and their contribution to the pathogenesis of asthma. However, 3-dimensional (3D) co-culture models are needed to enable the study of epithelial-mesenchymal crosstalk in the setting of the in vivo environment. In this review, we summarize studies using 3D co-culture models to assess how defective epithelial-mesenchymal communication contributes to chronic airway inflammation and remodeling within the asthmatic EMTU.

description: In der heutigen Zeit werden immer komplexere Materialien und Bauteile entwickelt. Diese besitzen oft anwendungsspezifische Eigenschaften und komplexe Geometrien, sodass das Abbilden und Charakterisieren der Bauteile mit herkömmlichen, bewährten Methoden an ihre Grenzen stößt. Die Eigenschaften eines Materials sind nicht nur von der makroskopischen Struktur abhängig, sondern sind eng mit der Mikrostruktur ver-knüpft. Daher ist es notwendig Analysemethoden zu entwickeln, die über Größenordnungen hinweg die Mikrostruktur abbilden und eine Charakterisierung ermöglichen. Ein weiterer Aspekt, der immer mehr an Bedeutung gewinnt, ist die Überwachung eines Bauteils über seinen gesamten Lebenszyklus hinweg. Hierbei ist zu berücksichtigen, dass eine Schädigung eines Bauteils bereits auf mikrostruktureller Ebene beginnt, bevor eine makroskopische Schädigung ersichtlich ist. Daher ist eine Überwachung mit zerstörungsfreien, hochauflösenden bildgebenden Verfahren notwendig. Zu den bildgebenden Verfahren zählen z.B. Ultraschall, Thermographie und die Röntgenbildgebung [4]. Diese beruhen auf der Wechselwirkung elektromagnetischer Strahlung mit Materie. Im Vergleich zu anderen bildgebenden Verfahren ermöglicht die Röntgenbild-gebung die dreidimensionale zerstörungsfreie Abbildung der inneren Struktur. Daher findet dieses Verfahren sowohl Einsatz in der Medizin, als auch im Bereich der Technik und wird somit ständig weiterentwickelt. Mit diesem Verfahren lassen sich die Fehler in einem Bauteil (Poren, Lunker, Fasern etc. [5]) auf mikroskopischer Ebene auflösen. Ein Röntgenmikroskop, welches für das Abbilden kleinster Fehlstellen geeignet ist, ist das in dieser Arbeit verwendete XRM-II NanoCT. Dieses auf einem Rasterelektronenmikroskop (REM) basierte System verwendet als Röntgenquelle ein nadelförmiges Target mit einem Spitzenradius von <100 nm [1]. Die geringe Größe des Targets, verursacht eine Reduzierung des Wechselwirkungsvolumen, was die Ausbildung eines kleineren Röntgenbrennflecks zur Folge hat. Auf Grundlage des Prinzips der geometrischen Vergrößerung können somit Strukturen im Nanometerbereich abgebildet werden. Jedoch verursacht die Verkleinerung des Wechselwirkungsvolumens eine Reduzierung der emittierten Röntgenquanten, wodurch die Intensität sinkt. Somit erhöht sich die Belichtungszeit, um scharfe Bilder zu erhalten. Das Ziel dieser Arbeit ist die Simulation des Set-Ups des XRM-II NanoCT‘s, um die spezielle Charakteristik besser zu verstehen. Anhand der Simulation werden Einflussfaktoren herausgearbeitet, deren Charakterisierung im realen Messaufbau sehr aufwendig ist. Aus den gewonnenen Erkenntnissen werden Optimierungsmög-lichkeiten entwickelt, um die räumliche Auflösung zu verbessern sowie höhere Röntgenintensitäten zu erreichen und damit einhergehend auch kürzere Messzeiten.

description: In dieser Arbeit wird das Ziel verfolgt, den Ansatz des thermischen Debondings von Klebeverbindungen auf das Anwendungsbeispiel eines zweilagigen Bodenbeschichtungssystems aus Epoxid und Polyurethan zu übertragen, um es dadurch leicht und sortenrein vom Betonsubstrat lösen zu können. Als Erwärmungsmethode bei der Aktivierung der Beschichtungen wurde Mikrowellenstrahlung gewählt, da sich diese bei optimaler Anwendung durch eine hohe Energieeﬃzienz auszeichnet. Die Kunststoﬀe mussten dazu gezielt mit verschiedenen Blähmitteln und Mikrowellenabsorbern modiﬁziert werden. Die Absorber sorgten dafür, dass die Absorption der elektromagnetischen Strahlung gesteigert wurde, sodass es zu einer Erwärmung der Polymerbeschichtungen kam. Andererseits waren Blähmittel erforderlich, deren Expansion zu einer Schwächung der Kohäsion in den Polymermatrizes und der Adhäsion an der Grenzﬂäche zwischen Beschichtung und Substrat führte. Zu den Zielen dieses Vorhabens gehörte, die mineralischen Anhaftungen nach dem Lösen der Bodenbeschichtungen zu verringern, und damit die Sortenreinheit zu erhöhen und die Recyclingfähigkeit des Beschichtungsssystems zu verbessern. Zunächst sollten die Auswirkungen verschiedener Mikrowellenabsorber und Blähmittel auf die mechanischen, rheologischen und thermochemischen Eigenschaften, und auf das Wechselwirkungsverhalten der Kunststoﬀe mit Mikrowellen untersucht werden. Nachfolgend wurden in einfach durchzuführenden Vorversuchen Materialkombinationen erwärmt und zum Aufblähen gebracht. Eine detaillierte Untersuchung des Debondingverhaltens der modiﬁzierten Beschichtungssysteme unter Mikrowellenbestrahlung indizierte erste aussichtsreiche Formulierungen. Im letzten Schritt wurden verschiedene Optimierungsschritte bzgl. Additivgehalt, Mikrowellenleistung und Antennengeometrie durchlaufen.

description: Platinum-based chemotherapies are effective agents in the treatment of a wide variety of human cancers. However, patients with recurrent disease can become resistant to platinum-based chemotherapy, leading to low overall survival rates. Activating transcription factor 3 (ATF3) is a stress-inducible gene that is a regulator of cisplatin-induced cytotoxicity. ATF3 protein expression was upregulated after cytotoxic doses of cisplatin treatment in a panel of cell lines. A chromatin immunoprecipitation assay showed that upon treatment with cisplatin, ATF3 directly bound to the CHOP gene promoter and this correlated with an increase in CHOP protein expression. In a 1200 compound library screen performed on cancer cell lines, disulfiram, a dithiocarbamate drug, was identified as an enhancer of the cytotoxic effects of cisplatin. This increased cytotoxic action was likely due to disulfiram and cisplatin’s ability to induce ATF3 independently through two separate mechanisms, namely the MAPK and integrated stress pathways. Furthermore, ATF3 protein and mRNA levels were variable amongst human ovarian and lung cancer tissues, suggesting the potential for basal expression of ATF3 to be predictive of cisplatin treatment response. Thus, understanding ATF3’s role in cisplatin-induced cytotoxicity will lead to novel therapeutic approaches that could improve this drug’s efficacy.
