Microchemistry Insights into Defects in Permanent Magnets for Improved Performance

Polin, Nikita

Permanent magnets are indispensable in modern technology, playing a central role in data storage, electric motors, MRI machines and increasingly in the green energy transition applications through their use in electric vehicles, wind turbines, and high-efficiency power electronics. Despite their critical importance, th...

Neighbors We Cannot Avoid

De Melo Novais, Tiago

Over the last two decades, Brazil has undergone a dramatic transformation from institutional political disagreement to a profound relational crisis of otherness. This study investigates how the unprecedented growth of polarization has transcended electoral disputes to become a defining feature of contemporary public li...

The mechanism of maturation of insulin-like growth factor-1

Cyril Craven

This study, to elucidate the role of des(1-3)IGF-I in the maturation of IGF-I,used two strategies. The first was to detect the presence of enzymes in tissues, which would act on IGF-I to produce des(1-3)IGF-I, and the second was to detect the potential products of such enzymic activity, namely Gly-Pro-Glu(GPE), Gly-Pro...

Wiener-Hopf techniques for the analysis of the time-dependent behavior of queues

Hadianti, Rieske

Summary In this thesis we study the time-dependent behavior of queueing systems. The study is focused on the queueing systems: 1. the $GI/G/1$ system, 2. the $GI/H_m/s$ system, 3. the Markovian Fluid Flow Model, the fluid flow model that is modulated by a Markov process, 4. the Semi-Markovian Fluid Flow Model, a genera...

Analytical, ecotoxicological and mechanistic investigation of SARS-CoV-2 agents and their ozonation-induced transformation products in surface waters

Bartels, Indra

Der Einsatz antiviraler Arzneimittel hat in den vergangenen Jahren deutlich zugenommen. Gerade während der SARS-CoV-2-Pandemie im Jahr 2020 wurden antivirale Wirkstoffe in großem Umfang eingesetzt. Diese Substanzen wie auch ihre Metaboliten gelangen nach der therapeutischen Anwendung und anschließender Ausscheidung in...

Adaptive Vector Finite Element Methods for the Maxwell Equations

Harutyunyan, Davit

The increasing demand to understand the behaviour of electromagnetic waves in many real life problems requires solution of the Maxwell equations. In most cases the exact solution of the Maxwell equations is not available, hence numerical methods are indispensable tool to solve them numerically using different methods....

De Instituto de Antropologia a Museu Câmara Cascudo: trajetórias científicas no Rio Grande do Norte, Brasil (1950-2010)

Silva, Jacqueline Souza

Esta tese analisa a trajetória do Instituto de Antropologia da Universidade do Rio Grande do Norte, posteriormente Universidade Federal do Rio Grande do Norte (UFRN), desde as condições que antecederam a sua criação, em 1960, até à transformação no Museu Câmara Cascudo (MCC), formalizada em 1973, e às configurações ass...

O Instituto Superior Técnico e a internacionalização de escolas universitárias - Política científica e práticas laboratoriais (1945-1974)

Marques, Cristina Isabel Mira dos Santos Pata

Esta tese reconstrói a modernização científica portuguesa a partir do Instituto Superior Técnico entre 1945 e 1974, observando os laboratórios como espaços de prática, circulação e diplomacia. Através da biografia de objectos e de trajectórias individuais, reconstituem-se redes de formação e colaboração que sustentaram...
