Characterization of coating on graphite anode material for lithium-ion batteries
2021
Master's thesis in Renewable energy (ENE500) To improve the performance of lithium-ion batteries, the graphite anode can be treated with special coating. Thus the charge transfer resistance through the material can be lowered and thereby enable e.g. faster charging. The amount of coating is essential the improve the performance. The thesis is investigating thermogravimetric and electrochemical impedance spectroscopy as a method to identify an optimal relation between the amount of coating and the charge transfer resistance. There is found that lower material resistivity gives a higher weight loss where it is assumed that the coating is oxidising, methods for both a relative difference in th…

2021
Pašreizējais bakalaura darbs pēta nākotnes vīzijas M. Atvudas antiutopiskajos romānos. Atvuda romānos “Kalpones stāsts” un “Oriksa un Kreiks” apspriež divas iespējamās nākotnes versijas, kas, lai gan atainotas dažādos gadsimtos, tomēr balstās uz mūsdienu pasaules apstākļiem un pagātnes notikumiem. Pētījuma mērķis ir salīdzināt nākotnes vīzijas romānos un atklāt gan to atšķirības un līdzības valdības un sabiedrības organizācijā, gan to, kā atainota tehnoloģiju un reliģijas ietekme. Pētījumā izmantotas tādas metodes kā teksta analīze, teorijas par postmodernismu, antiutopijām, totalitārajām sistēmām, tehnoloģijām, reliģiju un varu. Šī pētījuma rezultāti rāda, ka romāni piedāvā divas atšķirīga…
Analysis of antibody profile and correlation with disease severity in COVID-19 patients
2021
Antivielu atbildei ir būtiska loma cīņā ar SARS-CoV-2 infekciju un uz to noteikšanu balstās epidemioloģiskie pētījumi, kas ļauj spriest par vīrusa izplatību. Ar pašlaik pieejamo antivielu testu palīdzību var noteikt antivielas pret šī vīrusa S un N proteīniem, bet tās var veidoties arī pret citiem vīrusa antigēniem, taču to prevalence un funkcionālā loma nav zināma. Šajā darbā tika izstrādāts antigēnu mikrorindu tests, kas satur 30 SARS-CoV-2 antigēnus vai to fragmentus un ar tā palīdzību 103 COVID-19 pacientos izpētīta IgG, IgA, IgM un IgE antivielu veidošanās dinamika un prevalence. Rezultāti parādīja, ka pacientiem ar smagu un vidēji smagu slimības gaitu ir ievērojami augstāki IgG, IgA u…

Second-forbidden nonunique $��^-$ decays of $^{59,60}$Fe: Possible candidates for $g_A$ sensitive electron spectral-shape measurements
2021
In this work, we present a theoretical study of the electron spectral shapes for the second-forbidden nonunique $��^-$-decay transitions $^{59}\textrm{Fe}(3/2^-)\to\,^{59}\textrm{Co}(7/2^-)$ and $^{60}\textrm{Fe}(0^+)\to\,^{60}\textrm{Co}(2^+)$ in the framework of the nuclear shell model. We have computed the involved wave functions by carrying out a complete $0\hbar��$ calculation in the full $fp$ model space using the KB3G and GXPF1A effective interactions. When compared with the available data, these interactions predict the low-energy spectra and electromagnetic properties of the involved nuclei quite successfully. This success paves the way for the computations of the $��$-decay proper…

A New Technique of Invariant Statistical Embedding and Averaging in Terms of Pivots for Improvement of Statistical Decisions Under Parametric Uncerta…
2021
In this chapter, a new technique of invariant embedding of sample statistics in a decision criterion (performance index) and averaging this criterion via pivotal quantities (pivots) is proposed for intelligent constructing efficient (optimal, uniformly non-dominated, unbiased, improved) statistical decisions under parametric uncertainty. This technique represents a simple and computationally attractive statistical method based on the constructive use of the invariance principle in mathematical statistics. Unlike the Bayesian approach, the technique of invariant statistical embedding and averaging in terms of pivotal quantities (ISE&APQ) is independent of the choice of priors and represents …

Étude de statistiques combinatoires et de leur impact en optimisation évolutionnaire
2021
This thesis studies combinatorial objects, with both an algorithmic and a combinatorial point of view. In the combinatorial part, we take care first, the enumeration of Catalan words avoiding pairs of patterns of length three, presenting the proofs of each case with various enumeration methods. Catalan words are particular growth-restricted words counted by the eponymous integer sequence. More precisely, we systematically explore the structural properties of the sets of words under consideration and give enumerating results by constructive bijections or bivariate generating functions with respect to the length and descent number. Then, we study a sorting machine using two stacks in s…

“An unexploited potential” LifeLab Food and Health: Assessment and Development of Teaching and Learning Practices in the Norwegian School Subject Foo…
2021
Adhering to a healthy diet is key to a healthy life. Furthermore, investing in child and adolescent health has been highlighted as particularly important since it benefits the individual both now and long-term, as well as future generations. Based on this, schools have been identified as a crucial arena to reach this age group. In Norway, the school subject termed Food and Health (FH) educates students in food and nutrition and how this is related to health. Still, there is concern students are not acquiring the competencies highlighted in the curriculum since the number of formally qualified in FH is the lowest among all school subjects. Also, FH classes today primarily focus on cooking an…
Comment les parents déterminent les tailles de portions destinées à leur enfant ? Approche sociologique
2021
Introduction et but de l'étude: Il est établi que des tailles de portions majorées peuvent inciter les enfants à consommer au-delà de leurs sensations de faim, altérer leurs capacités d'autorégulation de la prise alimentaire et in fine induire un surpoids. Aussi les enfants sont-ils dépendants de l'offre alimentaire proposée par leur parent. Pour autant, peu d'études se sont intéressées à la façon dont les parents déterminent la taille des portions servies à leur enfant. Matériel et méthodes: Au moyen d'entretiens semi-directifs réalisés auprès de 5 pères et 32 mères d'enfants de 3 à 5 ans, nous avons cherché à décrire les pratiques parentales de détermination de la taille des portions serv…
Efectos del entrenamiento interválico de alta intensidad sobre variables cardiovasculares, funcionales y psicológicas en personas con diabetes tipo 1
2021
El entrenamiento interválico de alta intensidad, conocido como HIIT por sus siglas en inglés (high-intensity interval training), es un tipo de ejercicio físico que en los últimos años ha justificado ser una estrategia interesante para personas con enfermedades cardiometabólicas. En concreto, en personas con diabetes tipo 1 (DT1), el HIIT reduce el riesgo de hipoglucemia durante y después de la actividad, lo cual, es la principal barrera por la que esta población es, en su mayoría, físicamente inactiva. El propósito del presente estudio de investigación fue analizar los efectos que un protocolo de HIIT genera en personas adultas y sedentarias con DT1, sobre diferentes variables cardiovascula…

Five centuries of cod catches in Eastern Canada
2021
Abstract The fishery for Northern Atlantic cod (Gadus morhua) off Newfoundland and Labrador, Eastern Canada, presents the most spectacular case of an exploited stock crashed in a few decades by an industrial bottom trawl fishery under a seemingly sophisticated management regime after half a millennium of sustainable fishing. The fishery, which had generated annual catches of 100000 to 200000 tonnes from the beginning of the 16th century to the 1950s, peaked in 1968 at 810000 tonnes, followed by a devastating collapse and closure 24 years later. Since then, stock recovery may have been hindered by premature openings, with vessels targeting the remains of the cod population. Previous researc…
Konfliktlösung und rechtliche Stellung von Muslimen in Byzanz
2021
Die Frage nach der innergemeindlichen Konfliktlosung von Muslimen in Byzanz wird durch die Tatsache kompliziert, dass Muslime den Status einer anerkannten nicht-orthodoxen Minderheit im byzantinischen Recht bzw. politischen Denken nie erreicht haben. Im Gegensatz zu den ubrigen Minderheiten im ostromischen Reich bemuhten sich weder der Staat noch die Kirche um eine Klarung, welchen Platz Muslime im gesellschaftlichen Gefuge einnehmen sollten. Das Rechtssystem reflektierte im Wesentlichen die Sicht der spatromischen Gesellschaft des 6. Jahrhunderts: Es sah fur anerkannte Gruppen von Nichtorthodoxen – d. h. Juden, (christl.) Haretiker und Heiden – eigene Kategorien vor, nicht jedoch fur Musli…
La via errata delle Sezioni Unite al corretto riconoscimento della rilevanza usuraria degli interessi moratori
2021
Il saggio muove dalla recente sentenza delle Sezioni unite della Corte di cassazione sull'inclusione degli interessi moratori nell'ambito di applicazione della fattispecie dell'usura in astratto. La risposta data dalle Sezioni unite è positiva ed essa va pienamente condivisa, perché gli interessi moratori rientrano tra i costi dei finanziamenti, ancorché eventuali. Gli argomenti a sostegno di questa conclusione sono però totalmente errate e essi destano allarme perché si presentano chiaramente contra legem. The essay starts from the recent judgment of the Sezioni unite of the Court of Cassation on the inclusion of interests for non performance within the scope of the figure of usury so call…

Design og bruk av modelleringsoppgaver i klasserommet : En forskningsstudie om hvordan en designer modelleringsoppgaver
2021
Master's thesis in Mathematics education (MA502) Modeling is a mathematical skill that connects mathematics to the real world. Mathematical modeling has been a part of the new curriculum, LK20. Modeling will therefore get an extra attention in the teaching the mathematical competence of modeling. This is challenging for both teachers and students, and one of the reasons that it has not been prioritized in teaching mathematics. To teach modeling it requires good tasks to use in the classroom that challenge students on all level. In this study I investigated teaching modeling in the classroom with the research question: (1) How to model task that students can feel relevant and meaningful? (2)…
Investigating Motion Sickness in Racing Simulators using Virtual Reality and a Motion Platform
2021
Master's thesis in Multimedia and educational technology (MM506) Motion sickness has been a downside of virtual reality since its beginning. According to the "Sensory conflict" theory, simulation sickness and cybersickness often occurs due to the feeling of self-motion. This thesis aimed to investigate if a motion platform could mitigate simulation sickness. By using commercial available motion platform and virtual reality headset, the experiment had three conditions, one without any added motion, one with motion and the last with increased motion. Participants were put in a complete racing set to drive an Edge 6D motion simulator in Asseto Corsa. The participants drove a high-speed car for…

Stress/strain effects on electrochemical activity: Metallurgical/mechanical/interactions and surface reactivity
2021
Abstract Tribocorrosion is of complex nature as it involves multiscale interactions between mechanical, (electro-)chemical, physical, and material factors. The influence of mechanical stresses/strains on the surface reactivity of metallic alloys is described here. The electrochemical behavior and the corrosion resistance of engineering alloys are discussed in the presence of compressive and tensile stresses through different examples. The role of physical (formation of steps, roughness, microcracks), metallurgical (dislocations, crystallographic texture, and grain size), and chemical (passive film composition) changes induced by plastic deformation on electrochemical behavior and corrosion …
