Mean Arterial Pressure

description: Blood pressure measurement has been and continues to be one of the most important measurements in clinical practice and yet, it remains one of the most inaccurately performed. The use of oscillometric blood pressure measurement monitors has become common in hospitals, clinics and even homes. Typically, these monitors assume that the heartbeat rate remains stable, which is contrary to what happens in atrial fibrillation. In this thesis, a new method that provides a more precise estimate of Mean Arterial Pressure (MAP) is proposed using anon-invasive oscillometric blood pressure monitor. The proposed method is based on calculating a ratio of peak amplitude to trough amplitude for every pulse, then identifying where the ratio first reaches a value of 2. The performance of the proposed method is assessed by comparing the accuracy and variability of the readings against reference monitors -first in healthy subjects, then in atrial fibrillation patients. In healthy subjects and in atrial fibrillation patients, the proposed method achieved a performance accuracy that is well within the ANSI/AAMI SP10 protocol requirements of the reference monitors. The presence of atrial fibrillation diminished the performance of the reference monitor by increasing the variability of the reference readings. The proposed algorithm, on the other hand, performed better by achieving substantially lower variability in the readings than the reference device.

description: Abstract: Family history (FH) is a risk factor for many conditions that can affect pediatric patients. While there is no evidence of the clinical utility of FH taking in pediatrics and there is no standard of care as to FH taking, many suggestions were made as to what conditions should be covered in a pediatric FH assessment. There is also no evidence of the current practice. In this study the Theoretical Domains Framework was applied to FH taking and used to conduct semi-structured interviews with pediatricians to explore their FH taking practice. The pediatricians reported similar FH taking habits. Their FH taking was reported to include a wide range of conditions and determinants of health, and they used this information for a broad range of clinical tasks. FH taking in pediatric practice was reported to be complex and embedded with other aspects of practice. Résumé: Les antécédents familiaux (AF) sont des facteurs de risque pour plusieurs maladies affectant les patients pédiatriques. Alors qu'il n'y a ni données probantes concernant l'utilité des AF en pédiatrie ni normes pour la prise d'AF, plusieurs ont fait des suggestions quant à ce qui devrait être couvert par la prise d'AF. Il n'y a pas de données probantes décrivant la pratique actuelle de prise d'AF en pédiatrie. Dans cette étude, le Theoretical Domains Framework a été appliqué à la prise d'AF et utilisé afin de diriger des entrevues semi-structurées avec des pédiatres, dans le but de décrire leur pratique actuelle. Les pédiatres ont dit avoir des habitudes semblables quant à la prise d'AF. Cette dernière inclut plusieurs maladies et déterminants de la santé, et ils utilisent cette information pour plusieurs tâches. La prise d'AF en pédiatrie a été décrite comme étant complexe et très intégrée à leur pratique entière.

description: The rapid expansion of energy production from renewable sources and the imperative shift towards decarbonization across various sectors of the economy, such as industry, mobility, and agriculture, increase the significance of power electronic systems in the medium voltage range. In this context, galvanically isolated, modular topologies stand out as of particular interest. These systems offer adaptability to the desired voltage and power specifications of diverse applications through the use of identical module types. Crucial to the operation of these modules are auxiliary power supplies, including controllers, drivers, and sensors. However, the unique design of these modules and their interconnection present considerable challenges to the insulation strength of the auxiliary power supplies. Currently, suitable power supplies are hardly available commercially. Hence, the objective of this thesis is to develop a suitable auxiliary power supply for the power modules of a DC-DC converter with an isolation voltage of 8 kV. For this purpose the DC-DC converter is designed and the final PCB design integrates the Half-Bridge LLC resonant converter with a Synchronous Rectifier topology controlled through feed-forward control. Achieving a high isolation range is realized by designing the transformer using contactless power transfer principles, yielding a notable coupling efficiency of 71.5%. The operation is examined through analytical and simulation analyses of component current waveforms, providing insights into component current stresses and losses within the converter system.

description: Extensive literature exists pertaining to the topic of mentors and mentoring. To date by far the bulk of mentoring literature reflects activity in intra-organizational and corporate settings. The largest proportion of this literature and the resultant application of the term mentor in the workplace context has its origins in the US. The limited empirical research reflects this afore mentioned agenda, however, the principles and concepts applied to the term “mentor” within such settings are increasingly being transposed to the environment of the developing entrepreneur. A process of discovery has commenced, to explore the concepts of mentors and mentoring, and to better understand the role of such significant others in the start up and growth phases of new venture formation.

description: The problem of testing programs without test oracles is well known. A commonly used approach is to use special values in testing but this is often insufficient to ensure program correctness. This paper demonstrates the use of metamorphic testing to uncover faults in programs, which could not be detected by special test values. Metamorphic testing can be used as a complementary test method to special value testing. In this paper, the sine function and a search function are used as examples to demonstrate the usefulness of metamorphic testing. This paper also examines metamorphic relationships and the extent of their usefulness in program testing.

description: Subtribe Neochactina Soleglad & Fet, new subtribe   Type Genus. Neochactas Soleglad & Fet, new genus.
 Composition. This new monotypic subtribe is described here.
 Distribution. South America.
 Diagnosis. Synapomorphies. Chelal trichobothrium Db situated proximally on palm base, trichobothrium Dt distal of midpoint but proximal of trichobothrium Est. Important Symplesiomorphies. Neobothriotaxy Ch2 present on ventral surface of patella; neobothriotaxy Ch2 present on external surface of patella; pectinal middle lamellae composed of a one or two plates, semi-fused with anterior lamellae, fulcra if present, quite reduced; chelal trichobothrial est–esb–eb configuration angles away from fixed finger edge, eb close to finger edge.
 Discussion. This subtribe is the most primitive component in tribe Brotheini, where the juncture of trichobothria est–esb–eb angles away from the fixed finger edge, a condition commonly found in many of the chactoids. This orientation of est–esb–eb, plus the more basal positioning of the Db–Dt and  Et 3 –Et 5  trichobothrial series, separate Neochactina from its sister subtribe Brotheina.

description: Polymere Werkstoffe sind heutzutage in vielen Bereichen der Industrie und im Alltag nicht mehr wegzudenken. Eine besondere Rolle spielen dabei Schaumstoffe, insbesondere Partikelschäume, die sich durch eine flexible Formgebung und variierbaren Dichten für viele Anwendungen eignen. Kommerziell bestehen diese Schaumstoffe vorwiegend aus erdölbasierten Polymeren. Wie aber in vielen anderen Bereichen des Lebens steigt auch hier die Nachfrage für nachhaltigere Alternativen. In der vorliegenden Arbeit wurden deshalb Partikelschäume auf der Basis von PLA hergestellt. Dabei handelt es sich um einen aus natürlichen Ressourcen herstellbaren und biologisch abbaubaren Kunststoff. Um die Wärmeformbeständigkeit der PLA Schäume zu verbessern wurde eine hochkristallisierbare Type (4032D von Natureworks) ausgewählt. In vorangegangenen Arbeiten wurde bereits gezeigt, dass sich die Verarbeitung von teilkristallinen Polymeren zu Partikelschäumen als schwierig gestaltet. Durch Blenden mit dem Biopolymer PBS (BioPBS FD92 von PTT MCC Biochem Company) soll die Verarbeitbarkeit zu Partikelschäumen verbessert werden. Dabei soll der Einfluss von verschieden hohen PBS Anteilen auf die Verschweißbarkeit und Schäumbarkeit untersucht werden. Zunächst wurden expandierbare Partikel hergestellt und auf ihre Fähigkeit zum Aufschäumen und Nachexpandieren analysiert. Zur Untersuchung der Verschweißbarkeit wurde eine Methode entwickelt, bei der einzelne Beads miteinander verschweißt werden, um deren Verschweißgüte zu ermitteln. Anschließend wurden die geschäumten Partikel in einem Formteilprozess zu generischen Bauteilen verarbeitet. Auch hier wurde ein nachhaltiger Ansatz verfolgt, indem der neuere, im Gegensatz zur kommerziellen Heißdampfverschweißung, energie-effizientere Radiofrequenzprozess verwendet wurde. Die Bauteile wurden zuletzt auf ihre mechanischen und thermischen Eigenschaften untersucht. Hierzu wurden Querzugversuche durchgeführt und eine Methode zur Bestimmung der Wärmeformbeständigkeit von Schäumen entwickelt. Es konnte gezeigt werden, dass die Herstellung von hochkristallinen Polymerschäumen durch Blenden mit PBS ermöglicht wird. Mit höheren PBS Anteilen konnten die mechanischen und thermischen Eigenschaften verbessert werden, während die Schäumbarkeit hingegen abnahm. In einer zweiten Versuchskampagne wurde die gleiche PLA Type mit 50 % einer amorpheren PLA Type geblendet. Der Einfluss des PBS wurde auf die gleiche Weise analysiert. Eine Verbesserung der Eigenschaften durch zusätzliches Blenden mit PBS konnte hier nicht erreicht werden.

description: The side-effects of chemotherapy treatment are an increasingly important research focus as more cancer patients are reaching survivorship. While treatment allows for survival, it can also lead to problems which can significantly affect quality of life. Cognitive impairments after chemotherapy treatment are one such factor. First presented as anecdotal patient reports, over the last decade empirical evidence for this cognitive concern has been obtained. Much attention has been focused on post-chemotherapy research, yet little attention has been granted to these same patients’ cognition before treatment commences. Breast cancer (BC) patients face many obstacles before chemotherapy treatment such as: surgery and side-effects of anesthesia, increased cytokine activity, stress of a new disease diagnosis and upcoming challenges, and emotional burdens such as depression and anxiety. Many of these factors have independently been shown to affect cognitive abilities in both healthy populations as well as other patient groups. Therefore, the pre-treatment (or baseline) BC patient status warrants systematic study. This would then reduce mistakenly attributing carried-over cognitive deficits to side effects of chemotherapy. As well, it is possible that certain confounding variables may have neural manifestations at baseline that could be exacerbated by chemotherapy agents. The following thesis first presents a review paper which critically describes the current literature examining chemotherapy-related cognitive impairments (CRCIs), as well as possible confound variables affecting this population. Subsequently, three original research papers present pre-chemotherapy data showing significant neuroanatomical and neurofunctional differences in BC patients compared to controls. In particular, these neural differences are present in brain regions that have been reported in post-chemotherapy papers. This, as well as the effects of variables such as the number of days since surgery, depression and anxiety scores and more, support the initiative that research attention should increase focus on these patients at baseline in order to better understand their post-chemotherapy results.

description: Maize weevils, Sitophilus zeamais, are stored product pests mostly found in warm and humid regions around the globe. In the present study, acute toxicity via contact and residual bioassay and fumigant bioassay of 28 essential oils as well as their attraction–inhibitory activity against the adults of S. zeamais were evaluated. Chemical composition of the essential oils was analyzed by gas chromatography-mass spectrometry, and a compound elimination assay was conducted on the four most active oils (cinnamon, tea tree, ylang ylang, and marjoram oils) to identify major active constituents. Amongst the oils examined, cinnamon oil was the most active in both contact/residual and fumigant bioassays, and exhibited strong behavioral inhibitory activity. Based on the compound elimination assay and chemical analyses, trans-cinnamaldehyde in cinnamon oil, and terpinen-4-ol in tea tree and marjoram oils were identified as the major active components. Although cinnamon oil seemed promising in the lab-scale bioassay without rice grains, it failed to exhibit strong insecticidal activity when the container was filled with rice. When a cinnamon oil-based product was applied both in an empty glass jar and a rice-filled container, all weevils in the empty jar were killed, whereas fewer than 15% died in the rice-filled container.

description: Microplastics are small plastic fragments that are widely distributed in marine and terrestrial environments. While the soil ecosystem represents a large reservoir for plastic, research so far has focused mainly on the impact on aquatic ecosystems and there is a lack of information on the potentially adverse effects of microplastics on soil biota. Earthworms are key organisms of the soil ecosystem and are due to their crucial role in soil quality and fertility a suitable and popular model organism in soil ecotoxicology. Therefore, the aim of this study was to gain insight into the effects of environmentally relevant concentrations of microplastics on the earthworm Eisenia andrei on multiple levels of biological organization after different exposure periods. Earthworms were exposed to two types of microplastics: (1) polystyrene-HBCD and (2) car tire abrasion in natural soil for 2, 7, 14 and 28 d. Acute and chronic toxicity and all subcellular investigations were conducted for all exposure times, avoidance behavior assessed after 48 h and reproduction after 28 d. Subcellular endpoints included enzymatic biomarker responses, namely, carboxylesterase, glutathione peroxidase, acetylcholinesterase, glutathione reductase, glutathione S-transferase and catalase activities, as well as fluorescence-based measurements of oxidative stress-related markers and multixenobiotic resistance activity. Multiple biomarkers showed significant changes in activity, but a recovery of most enzymatic activities could be observed after 28 d. Overall, only minor effects could be observed on a subcellular level, showing that in this exposure scenario with environmentally relevant concentrations based on German pollution levels the threat to soil biota is minimal. However, in areas with higher concentrations of microplastics in the environment, these results can be interpreted as an early warning signal for more adverse effects. In conclusion, these findings provide new insights regarding the ecotoxicological effects of environmentally relevant concentrations of microplastics on soil organisms. © 2022 The Authors

description: Recent Australian research maps the contemporary patterns of concentration of spatial disadvantage, due to structural economic change, across metropolitan cities and regional centres (Baum et al., 1999). Within these studies, the communities identified as the most vulnerable to change, in terms of income levels, labour force engagement and the presence of disadvantaged residents, are social housing estates and areas of concentrated low income private rental housing. In tandem with the economic changes, concentrations of social housing tenants have been perceived as having significant associations, whether rightly or wrongly, with a range of issues including anti-social behaviour, crime, welfare dependency and depictions of a socially excluded underclass eschewing work and disengaged from mainstream norms and values. These depictions have been reinforced over the past few years internationally by civil disturbances experienced on social housing estates, including in Australia (Macquarie Fields and Redfern in New South Wales), France (St Denis, Poissy, Clichy-sous-Bois) and the UK (Bestwood, Nottingham)...[Introduction]

description: This thesis undertakes a close study of a single manuscript of the early 1320s, written at the priory of Fineshade, Northamptonshire. The manuscript contains a short chronicle and several documents related to the failed baronial rebellion of 1321-22. I argue that, in collaboration with the priory’s patrons, the Engayne family, the chronicler responds to the current situation with an attempt to create meaning from a time of crisis. In the process, he attempts to shape his material through patterns of style and thought inherited from both chronicle and hagiographical traditions, to make the present conform to the known and understood shape of the past. His success is limited by his inability to establish sufficient distance from traumatic events, a difficulty that many chroniclers seemed to encounter when they attempted to turn current events into meaningful historical narrative.

description: The effect of substrate surface topology on the interaction of living cells with inanimate substrates is a well-established phenomenon. When cells are placed on biomaterials, they outgrow protrusions called filopodia that sense surface features in their immediate surroundings and initiate the formation of stable cell adhesion complexes closer to the cell body. Adhesion proteins permit filopodia to constantly explore the surrounding microenvironment. A better understanding of the relationship of filopodia with surface features is highly relevant for exploiting custom-made surfaces to guide cell activity. In this work, mathematical modeling and simulation were used to describe different phenomena related to the interaction of a filopodium with its microenvironment, with the aim of reproducing experimentally observed phenomena associated to filopodia growth and interactions with substrates. The Kelvin Voigt model was used for the viscoelastic response of filopodia. Result predict filopodia protrusion under test conditions and helps improving our understanding on the effect of substrate topology on the biomechanical response of filopodial extensions.

Tribe Belisariini corresponds to the subfamily Belisariinae introduced by Lourenço (1998a; incorrect original spelling Belisarinae) who followed unpublished classification of Stockwell (1989). Belisariinae was originally placed in the family Troglotayosicidae (Fet & Sissom, 2000b).
 Biogeographic history. This unique, relict genus is the only Old World taxon belonging to the family Chactidae. This remarkable blind scorpion, which lives in litter and caves in the Pyrenees, has not been sufficiently studied; accounts of distribution and biology were given by Vachon (1945), Auber (1961), and Lacroix (1992).
 Diagnosis. Synapomorphies. Chelal trichobothrial series Db–Dt very basal, distance between Db and Dt quite small; pectinal fulcra absent. Important Symplesiomorphies. Patellar trichobothria distance between  esb 1  and  esb 2  much greater than distance between  em 1  and  em 2 ; ventral surface of leg tarsus dominated with setal pair configuration, median row of spinules essentially obsolete; orthobothriotaxic.
 Discussion. Taxonomic position of this genus has recently been influenced by its cave adaptations, i.e. the loss of eyes and pectinal fulcra. Both Stockwell (1989) and Lourenço (1998a) placed Belisarius in groups that were dominated by these suspect characters. It is important that Belisarius, along with genus Uroctonus, are the only members of Chactidae that exhibit orthobothriotaxy. The trichobothrial patterns of these two genera are remarkably similar (see Figs. 81 and 87). Moreover, the trichobothrial patterns found in these two scorpion genera play the key role in determining homologous orthobothriotaxic trichobothria in the other chactid genera which exhibit major neobothriotaxy. Of particular importance is the somewhat basal positioning of the patellar ventral trichobothria,  v 1 –v 3 , and the overall position and orientation of external series  esb 1 –esb 2 . See discussion under subfamily Superstitioniinae for more details on the previous taxonomic position of Belisarius.

Mikrostrukturbeeinflussung

description: Metallische Bauteile, die additiv gefertigt werden, weisen eine prozessbedingte charakteristische Mikrostruktur auf. Diese ist geprägt durch epitaktisch gewachsene, grobe, kolumnare Körner. Makroskopisch äußert sich diese Mikrostruktur in anisotropen mechanischen Bauteileigenschaften. Ein Ansatz Einfluss auf die Kornform, Korngröße und Textur zu nehmen, ist die Übertragung hochfrequenter mechanischer Wellen in Form von Ultraschall auf das Schmelzbad während der Erstarrung. Dadurch kommt es in der erstarrenden Schmelze zu Kavitation. Der Kollaps von Kavitationsblasen geschieht unter Freiset-zung von Druckwellen, welche die Ausbildung der dendritischen Erstarrungsstruktur unterbrechen. Daraus resultieren eine feinere, gleichachsigere Mikrostruktur und isotrope Bauteileigenschaften. Diese Arbeit beschäftigt sich mit der Anwendung von Ultraschall zur Mikrostrukturbeeinflussung für das Laser-Draht-Auftragschweißen. Für die Übertragung der Ultraschallwellen auf das Schmelzbad wurde ein System zur Anregung des gesamten Substrates realisiert. Anschließend wurde der Einfluss verschiedener Ultraschallamplituden auf die Mikrostruktur und Prozessstabilität für unterschiedliche Geometrien untersucht. Dabei zeigte sich eine negative Beeinflussung der Prozessstabilität. Um diese zu kompensieren, wurden verschiedene Ansätze zur Prozessstabilisierung konzipiert und getestet. Mittels Lichtmikroskopie, Rasterelektronenmikroskopie und Elektronenrückstreubeugung konnte eine Kornfeinung, Kornformbeeinflussung und Reduzierung der Textur in Abhängigkeit der Ultraschallintensität gezeigt werden.

description: This thesis introduces an efficient and robust approach for 3D reconstruction of complete head models with consistent parameterization and personalized shapes from several possible inputs. The system input consists of Cyberware laser-scanned data where we perform scanning task as well as publically available face data where (i) facial expression may or may not exist and (ii) only partial information of head may exist, for instance only front face part without back part of the head. Our method starts with a surface reconstruction approach to either transfer point clouds to a mesh structure or to fill missing points on a triangular mesh. Then, it is followed by a registration process which unifies the representation of all meshes. Afterward, a photo-cloning method is used to extract an adequate set of features in a semi-automatic way on snapshots taken from front and left views of provided range data. We modify Radial Basis Functions (RBFs) deformation so that it would be based on not only distance, but also regional information. Using feature point sets and modified RBFs deformation, a generic mesh can be manipulated in a way that closed eyes and mouth movements like separating upper lip and lower lip can be properly handled. In other word, such mesh modification method makes construction of various facial expressions possible. Moreover, new functions are added where a generic model can be manipulated based on feature point sets to consequently recover missing parts such as ears, back of the head and neck in the input face. After feature-based deformation using modified radial basis functions, a fine mesh modification method based on model points follows to extract the fine details from the available range data. Then, some post refinement procedures employing RBFs deformation and averaging neighboring points are carried out to make the surface of reconstructed 3D head smoother and uniform. Due to existence of flaws and defects on the mesh surface such as flipped triangles, self-intersections or degenerate faces, an automatic repairing approach is leveraged to clean up the entire surface of the mesh. The experiments which are performed on various models show that our method is robust and efficient in terms of accurate full head reconstruction from input data and execution time, respectively. In our method, it is also aimed to use minimum user interaction as much as possible.

description: Особые условия работы Байкальской лимнологической станции, основанной 1 октября 1928 г., связанные с длительной оторванностью от постоянного места жительства, и не в последнюю очередь особый психологический, «семейный» климат, существовавший на станции в «эпоху Г. Ю. Верещагина», способствовали тому, что внутри относительно небольшого научно-исследовательского коллектива зародились и работали несколько семейных пар.

description: Water quality monitoring has been widely studied over the years due to the important role water plays on our planet. Much research using the optical characterization of different materials has been done for the medicine, agriculture, and food industries. Usually, for optical characterization, turbidity sensors and spectrometers are mostly used. However, with the improvement of technology for the semiconductor industry, this project proposes to study optical properties such as transmission and diffuse reflection of different colored liquids with photodiodes and LEDs as an alternative of using spectrometers. It is proposed to give an insight into the state of water by using more affordable sensors in the market so the prototype would be easily reproducible, and accessible at a low cost. This project presents the design and implementation of a prototype for the optical characterization of distilled water containing different non-toxic solutes. For the experiment, 4 different food colorants were used and systematically varied in their concentration to test the prediction of the color and concentration of colorants using a rule-based system. The prototype developed was designed to be an effective low-cost alternative to the use of spectrometers. The project is expected to serve as a basis for further experiments and investigations for optical characterization of different liquids and LED/photodiode combinations.

Reflections on the Role of Consultation in the Delivery of Effective Educational Psychology Services

description: For many years educational and school psychologists from all over the world have emphasised the importance of consultation as a key approach to delivering effective services. However, there is a considerable body of literature indicating that the approach has not been widely adopted by educational psychologists in the UK and elsewhere. This paper considers some interconnected factors that might explain why educational psychologists may be reluctant to wholeheartedly embrace this approach. First, it considers the possibility that educational psychologists, who may claim to work in a ‘traditional’ way, are in fact using consultation regularly in their everyday practice, although not in the way that it is often defined in the literature. Second, the influence of the history of the profession, in which educational psychologists were described as being experts in psychometric assessment, may be acting as a barrier to adopting alternative practices. Third, unintentionally perhaps, the efforts of professional associations to promote educational and school psychology may reinforce the importance of maintaining traditional practices based on individual psychometric assessments of children thought to have special educational needs and disabilities. Finally the paper discusses the skills and competencies needed to work effectively as a school-based consultant and suggests that these pose particular challenges to new entrants to the profession who wish to work in this way. The paper concludes by suggesting that debates about the relative importance of individual work versus consultation present a false dichotomy. Both roles are central to the delivery of effective psychological services. Educational psychologists need to have the necessary skills and confidence in all areas of professional practice, being able to strike the right balance between the two approaches and sensitive to the situations where each is likely to be effective in dealing with the range of problems with which they are presented.
