description: The Worldwide Interoperability for Microwave Access, or WiMax, is a wireless communication technique based on IEEE 802.16 standards. Its advantage of sending high data rates over long distances, while using a single base station to cover a large area, has made this technique a flexible and reliable solution for public wireless networks. WiMax has two main types of networks: Fixed and Mobile. The most popular transceiver used in WiMax applications is the “Direct-Conversion Architecture” due to its high level of integration and less component requirements, which leads to reduced power dissipation. In Direct Conversion Architecture, the mixer is a key block in the transceiver chain. Depending on design specifications and constraints, different types of mixers may be considered. However, the most appropriate down converter mixer for WiMax applications is the Gilbert-cell mixer. This thesis will then explore the design of a down converter Gilbert-Cell Mixer within the realm of Fixed WiMax technology. This design was achieved in the commercial circuit simulator Advanced Design System (ADS) using the 0.15mm InGaAs pHEMT technology process provided by Win Semiconductor Crop.

electrolyzer plants

description: The primary goal of this investigation is to minimize the harmonic current emissions ofelectrolyzer plants. This will be achieved by focusing on the optimal design and layoutof the electrolyzer units and their grid components under different operating conditionsrelated to their loading capacity. Harmonics pose a significant challenge in power systems,especially in renewable energy setups, as they can impact system efficiency and stability. The methodology for this investigation involves modeling the green hydrogen plant and itscomponents responsible for generating harmonics in DigSILENT PowerFactory and performingsimulations in the frequency domain using the Harmonic Load Flow tool. The rectifiersof the electrolyzer units, which are significant sources of harmonic current emissions,are modeled as balanced harmonic current sources. The current emissions are providedwith their magnitudes and phase angles for the fundamental frequency and each harmonicorder. The harmonic voltages and harmonic currents at the different busbars and cablesare calculated with the harmonic impedances at the respective busbars. Four main scenarios were developed regarding the electrolyzer units and internal configurationof the plant. Additionally, a more significant number of operational cases consideringthe electrical operational limits of available electrolyzers were elaborated. For all four scenarios, the electrolyzer plant has a nominal capacity of 80 MW, consisting ofdifferent numbers of electrolyzer units rated either 1 MW or 5 MW. The electrolyzer plantis located within a short distance from a 120 MW wind farm. Both plants (electrolyzer andwind farm) are connected to the HV distribution network via Point of Common Coupling(PCC). A large number of simulations run for the different scenarios, and operational cases using12-pulse bridge rectifiers have clearly identified one configuration in each scenario withminimal harmonic current emissions on the transmission line to the PCC. This configurationalso appears optimal when using another rectifier technology with a different harmoniccurrent spectrum. This investigation demonstrated that the harmonic current emissions of the electrolyzerplant could be significantly reduced using an optimal design and layout of the electrolyzerunits and their grid components. This may lead to better performance, reduced losses, andeasier connection to the public grid.

Referred specimen —Incisor, JODA 4957.
Occurrence —UCMP V4834.
Description —The incisor is a long oval shape (deeper than wide) in cross section with a curved face, bearing no ornamentation. The incisor has a length of 11.92 mm.
Remarks — Copemys Wood, 1936 (known from the Barstovian Sucker Creek, Quartz Basin and Skull Springs localities) has an incisor size and shape consistent with this specimen and similarly lacks ornamentation (Lindsay 2008). The eomyids Pseudadjidaumo Shotwell, 1956 (known from the Barstovian Quartz Basin locality) and Leptodontomys Shotwell, 1956 (known from Arikareean, Clarendonian, and Hemphillian localities in Oregon) are far smaller than Copemys and JODA 4957 (Shotwell 1956, Korth and Samuels 2015). In addition, Pseudadjidaumo has rounded enamel and smooth incisors (Flynn 2008). The eomyid Pseudotheridomys Schlosser, 1926 (known from the Barstovian Skull Springs and Quartz Basin localities) is similar in size to Copemys, but it bears a transversely compressed incisor (Shotwell 1967). This specimen marks the only identifiable occurrence of cricetids in the Mascall Formation, collected from the Mascall Tuff. The lack of cricetid material, however, is most likely due to preservational issues.

Personalized drug prediction

description: Prescribing drugs to patients is usually performed based on their condition and the expertise of the medical practitioners. However, finding the most suitable drug is a complex task, as doctors might be influenced not only by the patient’s characteristics but also by factors like drug availability, insurance coverage, and even personal preference. With an increase in data availability and quality from vast knowledge bases focusing on individual traits and biological interactions, computational drug recommendation systems emerged. These tools hold the potential to improve the decision-making for drug prescriptions of a single doctor. In this work, we adapted the graph in-context learning framework Prodigy proposed by Huang et al. to perform personalized drug prediction for individual patients. First, patient-specific knowledge graphs were created using EHR data of patients from UK Biobank and the biomedical knowledge graph PrimeKG. Based on unique patient profiles, incorporating drug-, disease-, genomic-, and demographic information, disease-specific drugs are recommended by using patients with the same disease and known prescriptions as support examples. The performance of our proposed model was evaluated for three psychiatric disorders, namely depression, bipolar disorder, and schizophrenia, by assessing how well the drugs connected with the disease are considered as true over false drugs regarding treatment. Furthermore, we compared the results to a state-of-the-art baseline approach based on an RGAT and DistMult encoder-decoder framework. Even though a direct comparison is difficult due to the different prediction properties of the models, the result of the baseline was used as guidance for performance comparison. Overall, our model achieved higher AUC-ROC values than the disease-specific baseline models. Additionally, besides the comparatively high prediction ability, the model is very flexible for new diseases, only requiring a small number of support patients. Since no disease-specific fine-tuning is required, the calculations can also be conducted very quickly. Finally, as a real-world application, we compared the three highest-ranked drugs recommended by our system against the actually prescribed drugs for one random example.

description: Many legacy and emerging flame retardants (FRs) have adverse human and environmental health effects. This study reports legacy and emerging FRs in children from nine European countries from the HBM4EU aligned studies. Studies from Belgium, Czech Republic, Germany, Denmark, France, Greece, Slovenia, Slovakia, and Norway conducted between 2014 and 2021 provided data on FRs in blood and urine from 2136 children. All samples were collected and analyzed in alignment with the HBM4EU protocols. Ten halogenated FRs were quantified in blood, and four organophosphate flame retardants (OPFR) metabolites quantified in urine. Hexabromocyclododecane (HBCDD) and decabromodiphenyl ethane (DBDPE) were infrequently detected (<16% of samples). BDE-47 was quantified in blood from Greece, France, and Norway, with France (0.36 ng/g lipid) having the highest concentrations. BDE-153 and -209 were detected in <40% of samples. Dechlorane Plus (DP) was quantified in blood from four countries, with notably high median concentrations of 16 ng/g lipid in Slovenian children. OPFR metabolites had a higher detection frequency than other halogenated FRs. Diphenyl phosphate (DPHP) was quantified in 99% of samples across 8 countries at levels ~5 times higher than other OPFR metabolites (highest median in Slovenia of 2.43 ng/g lipid). FR concentrations were associated with lifestyle factors such as cleaning frequency, employment status of the father of the household, and renovation status of the house, among others. The concentrations of BDE-47 in children from this study were similar to or lower than FRs found in adult matrices in previous studies, suggesting lower recent exposure and effectiveness of PBDE restrictions. © 2022 The Authors

description: Background: To evaluate whether knee osteoarthritis (OA) manifestations predict depression and anxiety using cross-sectional and longitudinal prediction models. Methods: A population-based cohort (n = 122) with knee pain, aged 40–79, was evaluated at baseline, 3 and 7 years. Baseline predictors were: age decade; sex; BMI ≥ 25; physical exam knee effusion; crepitus; malalignment; quadriceps atrophy; flexion; flexion contracture; Kellgren-Lawrence (KL) x-ray grade (0/1/2/3+); WOMAC pain ≥25; WOMAC stiffness ≥25; self-reported knee swelling; and knee OA diagnosis (no/probable/definite). Depression and anxiety, cutoffs 5+ and 7+ respectively, were measured via the Hospital Anxiety and Depression Scale. We fit logistic models at each cycle using multivariable models selected via lowest Akaike’s information criterion. Results: Baseline depression model: sex (female OR = 0.27; 0.10, 0.76) and KL grade (KL 1 OR = 4.21; 1.31, 13.48). Three-year depression model: KL grade (KL 1 OR = 18.92; 1.73, 206.25). Seven-year depression model: WOMAC stiffness ≥25 (OR = 3.49; 1.02, 11.94) and flexion contracture ≥1 degree (OR = 0.23; 0.07, 0.81). Baseline anxiety model: knee swelling (OR = 4.11; 1.51, 11.13) and age (50–59 vs. 40–49 OR = 0.31 [0.11, 0.85]; 60–69 OR = 0.07 [0.01, 0.42]). Three-year anxiety model: WOMAC stiffness ≥25 (OR = 5.80; 1.23, 27.29) and KL grade (KL 1 OR = 6.25; 1.04, 37.65). Seven-year anxiety model: sex (female OR = 2.71; 0.87, 8.46). Conclusion: Specific knee OA-related manifestations predict depression and anxiety cross-sectionally, 3 years in the future, and for depression, 7 years in the future. This information may prove useful to clinicians in helping to identify patients most at risk of present or future depression and anxiety, thus facilitating preemptive discussions that may help counter that risk.

description: In today’s work place where corporations allow employees to use their own smart phones to access their company’s network and sensitive data, it is essential to ensure the security of said data. When an employee smart phone is compromised, companies will rely on the remote wipe command that attempts to remove sensitive data. In this thesis, we analyze the effectiveness of remote wipe commands on the Apple iPhone and Android model devices and demonstrate how data can be recovered following a remote wipe procedure. We conduct two experiments on each device to verify whether remote wipe is a viable defense mechanism or not. Furthermore, we touch on the subject of mobile forensics used by law enforcement and review methods and techniques used to recover data for use as evidence in criminal cases.

description: Active networks have been recently highlighted as a key enabling technology to obtain immense flexibility in terms of network deployment, configurability, and customized packet processing. However, this flexibility is often achieved at the cost of router performance. In this paper, we present a three-level node architecture that combines flexibility and high performance of network nodes. We design and implement an active network application for real-time speech transmissions on top of this three-level platform. In our application, plug-in modules are downloaded onto certain network nodes to monitor packet loss rate of voice streams and to perform application-specific packet processing when necessary. In particular, we propose to perform loss concealment algorithms for voice data streams at active network nodes to regenerate lost packets. The regenerated speech data streams are robust enough to tolerate further packet losses along the data path so that the concealment algorithms at another downstream node or at the receiver can still take effect. We call our approach reactive concealment for speech transmission to distinguish it from concealment performed at the receiver and also proactive schemes like Forward Error Correction. Our approach is bandwidth-efficient and retains the applications’ end-to-end semantics.

description: A degradable/polar/hydrophobic/ionic (D-PHI) polyurethane with properties intended to promote tissue regeneration in a small diameter peripheral artery vascular graft was evaluated for cell biocompatibility and growth. Films were cast in polypropylene 96 well plates for monocyte/endothelial cell (EC) co-culture in vitro studies and porous scaffold discs were implanted in an in vivo subcutaneous mouse model. After 7 days in culture the co-culture demonstrated cell adhesion and growth, low esterase activity (a measure of degradative potential and cell activation), no detectable release of pro-inflammatory cytokine (tumour necrosis factor -α) but measurable anti-inflammatory interleukin (IL)-10. The EC and the co-culture expressed the EC biomarker CD31, whereas the monocyte monoculture did not. Cytokine array analysis of the in vivo characterization of D-PH supported an anti-inflammatory phenotype of cells at the site of the implant. Levels of IL-6 significantly decreased over time while IL-10 was significantly higher at 6 weeks post implant. TNF-α levels did not change significantly from 24 hours onwards, however the trend was towards lesser amounts following the initial time point. Histological analysis of the explanted scaffolds showed excellent tissue ingrowth and vascularization. A live/dead stain showed that the cells infiltrating the scaffolds were viable. Both the in vitro and in vivo results of this thesis indicate that D-PHI is a good candidate material for tissue engineering a peripheral artery vascular graft.

description: It is generally thought that in amphibians, thyroid hormones (THs) regulate metamorphosis, while sex steroids (estrogens and androgens) regulate gonadal differentiation. However, inhibition of TH synthesis in frogs alters gonadal differentiation, suggesting instead that these two endocrine axes interact during development. Specifically, THs may be involved in male development, while estrogens may inhibit tadpole metamorphosis. However, we do not currently know the mechanisms that account for these interactions, let alone how such mechanisms may differ between species. To develop and test new hypotheses on the roles of sex steroids and THs, I first examined transcriptional profiles (mRNA) of enzymes and receptors related to sex steroids and THs during embryogenesis and metamorphosis in Silurana tropicalis. Tadpoles were exposed to either an estrogen synthesis inhibitor (fadrozole) or TH (triiodothyronine, T3) during early larval or tadpole development. Acute exposures of S. tropicalis to fadrozole or T3 during early development resulted in increased expression of androgen- and TH-related genes in whole body larvae, while chronic exposure to fadrozole during metamorphosis affected gonadal differentiation but did not affect tadpole development. On the other hand, acute exposure to T3 during metamorphosis increased the expression of androgen-related transcripts both in the brain and gonad. In S. tropicalis, the results suggested that cross-talk is primarily in one direction (i.e., effect of THs on the reproductive axis) with a strong relationship between TH and androgen status. Lastly, I established developmental transcript profiles and investigated T3 regulation of brain and gonad transcripts in Engystomops pustulosus. I then compared these results with S. tropicalis and an earlier study in Lithobates pipiens. While each species developed with similar profiles, they differed in their response to T3. Exposure to T3 resulted in either an increase in androgen-related genes (S. tropicalis) or a decrease in estrogen-related genes (E. pustulosus and L. pipiens). In conclusion, these data demonstrated that cross-talk mechanisms differ among these three evolutionary separate species, but in all cases, T3 appears to affect the balance of sex steroids, stimulating the androgen system and providing potential mechanisms of the masculinising effects of THs. These results will contribute to understanding the mechanisms of hormone interactions and their evolutionary basis in frogs.

description: Cette thèse s’intéresse à l’univers féminin de La diaspora des Desrosiers, la toute dernière série romanesque de Michel Tremblay, auteur québécois célèbre au Canada français depuis la fin des années 1960. À la demande de ses lecteurs , Tremblay décide, plus de dix ans après la publication de ses récits autobiographiques, d’écrire l’enfance d’un de ses personnages les plus connus : Nana. Dans La traversée du continent, La traversée de la ville et La traversée des sentiments, les lecteurs ont donc droit aux aventures de la jeune Rhéauna, qui présente déjà des ressemblances avec son personnage tel qu’il apparaît dans d’autres œuvres de Tremblay. Ces romans (ainsi que les récits et pièces de théâtre) font ici pour la première fois l’objet d’une lecture au féminin approfondie qui s’attarde au thème de la transgression sous trois formes principales : la transgression du rôle traditionnel des femmes, de l’espace qui leur est traditionnellement imparti, et de la parole féminine traditionnelle. D’abord, elle souligne les écarts de la norme des personnages féminins de La diaspora des Desrosiers par rapport aux attentes d’une société patriarcale qui leur réserve peu de rôles à l’abri de la marginalité. Ensuite, elle présente des femmes qui s’échappent par moments de la sphère privée établie pour les confiner, et ce, grâce à leurs déplacements géographiques et mentaux. Finalement, elle se penche sur le rire au féminin en tant qu’infraction (par l’ironie et par l’humour) à la parole féminine traditionnelle par le truchement de personnages féminins qui rient en plus de faire rire.

description: This mixed-methods single case study explored how outcome-based instructional design can be used to incorporate social software into an existing e-learning course. Pre-service teachers enrolled in a teacher education program at a Canadian university volunteered to participate in a study where social software was incorporated into a foundations course to facilitate digital literacy development, social objects production, and reflection on how these experiences connect to future teaching practice. The instructional design process was guided by a conceptual framework and informed by W(e)Learn, a well-tested e-learning design and evaluation framework. The quantitative and qualitative data were collected from the instructional designer’s journal, participant surveys, course records and interviews. Findings provided a comprehensive view of the effectiveness of outcome-based instructional design. In general, participants achieved the expected learning outcomes for this study. There were also unexpected outcomes. For example, some learners created a virtual community of practice. Some learners had an influence on their in-service teacher’s use of social software in teaching and learning. The findings supported the literature that states an outcome-based instructional design approach can facilitate learning. The findings also revealed why participants used social software in their teaching (e.g. awareness, usefulness, and school environment). In addition, these findings can inform school board policy with regard to supporting the use of social software in teaching and learning. The integration of qualitative and quantitative findings revealed convergence and divergence between the two types of data. In addition the findings informed directions for further research, including the relationship between learners’ satisfaction and learning experiences as well as the achievement of learning outcomes. The corroboration of data also identified specific effective and iii imperfect areas of the instructional design strategies, which, in turn, informed the revision of the conceptual framework for outcome-based instructional design. This study found W(e)learn to be effective in guiding outcome-based instructional design and analyzing the achievement of expected learning outcomes. The study also contributes to theory by recommending the inclusion of two new elements into W(e)learn. Painstakingly recording the instructional design process in a journal resulted in documented practical information and lessons learned that may guide and benefit instructional designers and educators who want to incorporate software into their learning activities.

description: Mannosylerythritol lipids (MEL) are microbial glycolipid biosurfactants with many interesting properties and great potential for commercial application, for example in household detergents or cosmetics. Despite the general interest in those molecules and the need for a robust process, studies on their production in bioreactors are still scarce. The aim of this thesis was to develop a defined and well-controlled fermentation process for MEL production that can be scaled-up to industrial scale. Seven fungi from the family of Ustilaginaceae were screened for their capability of MEL production in combination with different plant oils and the resulting structures were characterized. A defined mineral medium for cell growth and production was established, and a fed-batch fermentation process was developed for the most promising producer strain Moesziomyces aphidis. The results of this dissertation will contribute to further explore the potential of MEL in surfactant applications and to develop a suitable industrial production process in the future.

description: Context aware functionalities are functionalities that consider context to produce a certain system behavior, typically an adaptation or recommendation. From a requirements engineering viewpoint, building a context-aware system calls for context modeling, an early step that comprises a set of activities responsible for understanding what the context is for the application domain, and how the context influences user tasks of interest. As a result, a context model is created and is expected to support requirement engineers in identifying new context-aware functionalities to improve these user tasks. In practice, however, context modeling activities have been disregarded due to their high complexity. As a consequence, contexts are created where only few contextual elements are combined, which leads to opportunities for discovering unexpected context-aware functionalities being missed. In this thesis, this problem is addressed by using a data-driven approach to analyze contextual data and automate context modeling. For this purpose, a data-driven context modeling framework has been developed to support the elicitation of context-aware functionalities.

description: The design response spectrum is typically the starting point of most codified seismic design and assessment procedures and is used predominantly to prescribe the applied inertia forces induced by earthquake ground motions. This paper introduces and reviews modern concepts related to the effective development and application of earthquake design response spectra, including the conventional acceleration response spectrum, the velocity spectrum, and the displacement spectrum. It further briefly reviews the concepts of the inelastic response spectrum and the capacity spectrum. A number of the ideas presented are targeted particularly at assisting practising engineers working in low- and moderate-seismicity environments. The principal purpose is to enlighten engineers to modern concepts in response spectra development, in order to subsequently facilitate the effective use of the information contained in an earthquake response spectrum for both analysis and design applications.
'A woman is precious': constructions of Islamic sexuality and femininity of Turkish-Australian women
Creators: name: Zevallos, Zuleyka
Publisher: name: Swinburne
Year: 2024

description: This paper analyses data from 25 qualitative interviews to explore the relationship between religion, gender and sexuality for Turkish-Australian women aged 18-26. It argues that the hijab (headscarf) symbolises an idealised Muslim femininity because it signifies to the participants a high level of personal religious commitment and it also embodies the Islamic mores of modesty and self-respect regarding their sexuality. Participants in the study explained that 'a woman is precious like diamonds, that's why we have to keep her covered'. While they displayed a sense of agency in perceiving their 'liberation' from sexual objectification through the hijab, some ambiguity arose from their conceptualisation of an ideal Muslim femininity. This ambiguity is tied to Islamic and Australian narratives of female sexuality, which position women in a role responsible for regulating sexual expression and sexual attraction in both the private and public spheres.

description: Biologisch abbaubare Kunststoffe gewinnen in der Landwirtschaft zunehmend an Bedeutung, da konventionelle Mulchfolien oft zu einer Ansammlung von Kunststoffpartikeln im Boden führen. Diese Partikel sind potenziell umweltschädlich, da sie in Form von Makro-, Mikro- und Nanoplastik im Boden verbleiben. Ziel ist es, den Abbau von drei biologisch abbaubaren Kunststoffen (Poly(butylenadipat-co-terephthalat) (PBAT), Poly(butylensuccinat-co-terephthalat) (PBST) und Poly(3-hydroxybutyrat-co-3-hydroxyhexanoat) (PHBH)) im Boden und im Süßwasser zu untersuchen. Im Fokus steht die Bestimmung der Eigenschaftsveränderung der Materialien und die Auswirkungen auf die Bodenqualität, insbesondere in Bezug auf die Pflanzentoxizität, die Nitrifikationsaktivität und die Toxizität gegenüber Regenwürmern. Die Arbeit zeigt, dass die Abbauraten dieser Materialien variieren und dass insbesondere PBAT und PBST trotz des ähnlichen chemischen Aufbaus Unterschiede in der Desintegration aufweisen. PHBH zeigt hingegen einen gleichmäßigeren Abbau, ohne optische und haptische Veränderungen. Weiterhin wurde festgestellt, dass der Einsatz dieser Folien einen Hinweis auf eine verminderte Nitrifikationsaktivität des Bodens zeigen kann.
description: Biodegradable plastics are becoming increasingly important in agriculture, as conventional mulch films often lead to the accumulation of plastic particles in the soil. These particles are potentially harmful to the environment, remaining in the soil in the form of macro-, micro-, and nano plastics. The goal of this study is to investigate the degradation properties of three biodegradable plastics-Poly (butylene adipate-co-terephthalate) (PBAT), Poly (butylene succinate-co-terephthalate) (PBST), and Poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBH)-in soil and freshwater. The focus is on determining changes in the properties of the materials by measuring the mass loss of the samples, the chemical alteration of the materials, and their effects on soil quality, particularly in relation to plant toxicity, nitrification activity, and toxicity towards earthworms. It can be demonstrated that the degradation rates of these materials vary and that PBAT and PBST, despite their similar chemical composition, show differences in their disintegration. PHBH, on the other hand, exhibits a more uniform degradation without notable optical and tactile changes. Furthermore, it was found that the use of these films may indicate a slight reduction in the nitrification activity of the soil.

Unter Berücksichtigung der Prozesscharakteristik der Werkstoffextrusion wurden die Zusammen-hänge zwischen thermischer Prozessführung, Benetzung und Haftfestigkeit betrachtet. Die Thermographie ermöglicht eine Prozesskontrolle des thermischen Fügeprozesses. Benetzung und Adhäsion verbessern sich mit zunehmender Substrattemperatur. Unterschiede zwischen den Polymerwerkstoffen werden mit der chemischen Struktur und den Eigenschaften der Polymere korreliert. Ein werkstoffübergreifendes empirisches Modell zur Abschätzung der Haftfestigkeit basierend auf dem Benetzungsverhalten und den Polymereigenschaften wird vorgestellt. PETG-Aluminium-Verbunde mit geeigneter thermischer Prozessführung weisen die höchste Kurzzeithaftfestigkeit und Alterungsbeständigkeit auf und genügen den Anforderungen an eine strukturelle Klebung.
description: Technical relevant joints between aluminum substrates (EN AW 6082) and the extruded polymers ABS, PETG and PLA are investigated. Thermal processing, wetting and adhesion are correlated with each other, while considering the material extrusion process characteristics. Thermography enables process control of the thermal joining process. Wetting and adhesion are improved for increased substrate temperatures. Polymer specific differences in wetting and adhesion are correlated with the polymers chemical structure and properties. Based on wetting and polymer properties, an empirical model to estimate adhesion is presented. Proper processed PETG-Aluminum-joints offer the highest bond strength and aging resistance, sufficing the demands of a structural adhesive joint.

description: The bioavailability of an orally administered small molecule is often dictated by drug-specific physicochemical characteristics and is influenced by many biological processes. For example, in fed or fasted conditions, the transit time within the gastrointestinal tract can vary, confounding the ability to predict the oral absorption. As such, the effects of food on the pharmacokinetics of compounds in the various biopharmaceutics classification system (BCS) classes need to be assessed. The consumption of food leads to physiological changes, including fluctuations in the gastric and intestinal pH, a delay in gastric emptying, an increased bile secretion, and an increased splanchnic and hepatic blood flow. Despite the significant impact of a drug’s absorption and dissolution, food effects have not been fully studied and are often overlooked. Physiologically-based pharmacokinetic (PBPK) models can be used to mechanistically simulate a compound’s pharmacokinetics under fed or fasted conditions, while integrating drug properties such as solubility and permeability. This review discusses the PBPK models published in the literature predicting the food effects, the models’ strengths and shortcomings, as well as future steps to mitigate the current knowledge gap. We observed gaps in knowledge which limits the ability of PBPK models to predict the negative food effects and food effects in the pediatric population. Overall, the further development of PBPK models to predict food effects will provide a mechanistic basis to understand a drug’s behavior in fed and fasted conditions, and will help enable the drug development process.

description: Television has developed dramatically over the past six years in Afghanistan with a potential for providing extensive health information to its viewers, yet little is known about the coverage of health issues on Afghan television. Using the theories of agenda-setting and framing, and social norms approach this study explored what health-related topics were covered, how they were covered, and what sociocultural practices were broadcasted by the major Afghan private, national televisions. The study used a sample of six constructed weeks in 2010 of two leading private, national television networks. Firstly, the study found that priority health problems such as maternal and child health, communicable disease and mental health received very less coverage. Secondly, however, individual-level and societal-level causes were blamed equally for the health problems; individual behaviour solutions were the favourite choice of the media, turning a blind eye to government weakness and organizational solutions. Thirdly, self-prescription, religious and traditional health seeking behaviour, and gender inequity were routine practices reflected on television. As the first content analyses of the coverage of health-related issues in Afghanistan, the study provides public health professions, the Afghan media and policy makers a broad picture of health information available to the public on the leading Afghan television stations.

description: This paper describes the effect of individual additives that are present in typical masterbatch formulations; the role they play in modifying physical properties and processability of blends based on RPET. Additives such as titanium dioxide, carbon black, linear low-density polyethylene and polyethylene wax are often incorporated into the composition of masterbatch. Blends based on these additives have been analysed for shifts in thermal transition points, levels of crystallinity and physical properties such as tensile and impact strength. The results show that, at the addition rates used, some additives had significant effects on processability and crystallinity, negligible effects on physical properties and antagonistic effects were noted when additives were combined.

Investigation of Transpressive Deformation Zones in the North Caribou Greenstone Belt (NW Superior) and Relationships with Regional Metamorphism: Implications for the Technothermal Evolution during Archean Cratonization

description: The Archean North Caribou greenstone belt (NCGB) possesses abundant transpressive deformation zones on its northern margins, which appear to have formed under amphibolite facies conditions. Protracted deformation and regional metamorphism are coeval with widespread magmatism and accretion events in the Superior Province, yet the importance of these shear zones in the tectonic evolution of the NCGB is equivocal. Structural analyses support a transpressive system that strongly implicates horizontal tectonism. This is partly in contrast with some currently proposed models for Archean greenstone belts suggesting synchronous vertical and horizontal movements. Geochemical and microstructural analyses from shear zones indicate heterogeneous deformation/fluids conditions on a km-scale. Monazite and mica geochronological ages indicate metamorphism and deformation occurring during the amalgamation of the Superior craton from ca. 2.75 to 2.4 Ga. The high metamorphic grade background may obscure tectonic signatures, yet some structural and geochemical characteristics remain consistent with other greenstone belts where vertical and horizontal displacement are recorded.

description: This study addresses the theatre of Romeo Castellucci’s group, the Socìetas Raffaello Sanzio, and its director’s engagement with visual arts. In particular, the study analyses the tenth episode M#10 Marseille of Castellucci’s major production Tragedia Endogonidia, a work composed of 11 episodes, each dealing with a European capital. Using the notion of intermediality, this thesis demonstrates how an intermedial performance integrates questions and principles connected with visual arts within the framework of a new concept of performance called ‘interformance’. The author introduces Henk Oosterling’s definition of intermediality where he uses Derrida’s theory of différance to explain the notion as a back and forth movement created by the interaction of media whose differences produce tension within the spectators. This tension suspends and postpones the audience’s meaning generation, thus opening the possibility of a multiplicity of meanings. As a result, the meaning of an interformance directly depends on the interrelationship of media and the subjectivity of the spectator.

description: Seafaring has a centuries-old tradition. Maritime trade started long before the existence of freight airplanes, covering large distances and thereby enabling the exchange of goods between distant parts of the world. Today, the ship still is the most economic means to transport cargo between the continents. For on-board personnel, merchant ship voyages are long and straining, with a lot of time spent miles apart from family and friends. It is for this reason, amongst several others, that the MUNIN project has been launched. MUNIN means Maritime Unmanned Navigation through Intelligence in Networks and is a research project funded by the European Union. The project is a collaboration of universities, research institutes and industry partners in five different countries and seeks to establish a framework for unmanned, autonomous freight shipping. One of the project partners is the Fraunhofer Center for Maritime Logistics and Services CML based in Hamburg, Germany, where this thesis was written. Within the scope of the MUNIN project, the thesis at hand aims at assessing the risks associated with unmanned maritime transport with the help of fault tree analysis. Chapter 2 provides a brief look at other unmanned and autonomous transport systems and compares them to unmanned ships. Chapter 2 outlines the MUNIN project and gives details on the vessel, on-board systems and the operational modes that will be relevant for the following risk analysis. In order to carry out the latter, techniques for hazard identification and risk assessment need to be applied. An overview of typically used methods is given in chapter 4. After choosing a focus for the risk assessment in chapter 5 and the identification of hazards in chapter 6, accident scenarios are developed using event trees and fault trees in chapter 7. Their qualitative assessment is followed by a quantitative assessment in chapter 8. Chapter 9 deals with the estimation of accident consequences, which is the basis for obtaining the final results of the risk assessment in chapter 10. It also includes a critical reflection on the analysis, its results and a conclusion.
