Disorienting Resilience: Exploring Resilience with Women Graduate Students in Design-Related Programs

Donaldson, Christina 05 1900 (has links)
The term resilience is overused and under theorized. This dissertation challenges prevailing resilience discourses, exploring the tensions of embodied and experiential relationships with resilience that complicate the overly reductive and overly positive notion of resilience as a virtue of neoliberal subjects. Understanding resilience in the context of contemporary Western society necessitates unraveling the societal conditions shaped by the dominant neoliberal capitalist ethos of production. To address these problems, I explore how resilience is lived in the impasse of the crisis ordinary. Guided by affect theory, critical phenomenology, and queer theory, my study centers on ambiguity, subjectivity, and normativity in order to contend with the complexities and contradictions of resilience. Through a novel impassive bricolage methodology, I explore the lived and embodied experiences of resilience through relational, reflexive, and creative processes of autohistoria-teoría, flashpoint methodology, heuristic inquiry, and a participatory, reflexive thematic analysis. This study engaged with three women co-researchers who have recently completed graduate programs in design-related fields. Data collection included written reflections, interviews, focus group recordings, and creative works. Analysis revealed three central themes: disorientation, movement, and disconnection. For these co-researchers, resilience emerged as a complex and ambiguous phenomenon, responding to the push and pull between self and the normative world. Reconceptualizing resilience as emerging from and including queer affects, I redirect focus from linear progression, attending instead to ambiguous and awkward movements of the impasse. By unraveling resilience, my project opens up ways to live the impasse by loosening attachments to good-life fantasies and embracing happiness without guarantees.

Elektrolyty s rozpouštědly typu sulfolanu / Electrolytes based on sulfolan and similar solvents

Máca, Josef January 2011 (has links)
Submitted thesis deal with study of aprotic electrolytes in order to increase the safety for use in lithno – ionts accumulators. Increase of safety is specified by measuring the flash point of each electrolytes, at the same time are evaluated also other parameters important for use in accumulators. For determine the window of temperatures where the electrolytes can work is measured by melting point. The melting point is measured by cryoscopy. From electrical properties is measured specific conductivity of the electrolyte.

Aprotické elektrolyty pro lithno-iontové akumulátory s vyšší teplotní stabilitou / Aprotic electrolytes for lithium-ion batteries with higher temperature stability

Bajer, Michal January 2013 (has links)
Master thesis deals with safety of aprotic electrolites used in lithium – ion accumulators. Beside conductivity and viscosity of electrolytes is work focused to flashpoint of electrolytes with flame retardants. In main part of work is shortly explained lithium ion accumulator used materials and fundamentals. Flame retardancy mechanisms and used materials are disscussed too. In practical part work deals with description of used measuring methods and evaluation of gauged data. At least optimal composition of electrolyte with flame retardant is proposed.

Vliv solí na vlastnosti aprotických elektrolytů / The salt influence on aprotic electrolytes

Pojer, Stanislav January 2013 (has links)
This thesis deals with the liquid aprotic electrolytes with solvent on the basis of sulfolane blends with other solvent, in combination with the sodium and lithium salts. In these electrolytes are evaluated their properties due to their use in lithium - ion batteries in terms of safety and electrical properties. For safety risk is measured flashpoint and for electrical properties is measured electrical conductivity for selected samples are intended capacities of double layers.

Aprotické elektrolyty s retardery hoření / Aprotic electrolytes with fire retardant

Hlava, Kamil January 2015 (has links)
This thesis deals with liquid aprotic electrolytes based on sulfolane with added flame retardant. The theoretical part of the thesis explains concepts - mainly aprotic electrolytes, flame retardants, and their practical use. It also discusses lithium - ion accumulators and materials used in them while focusing on the electrolyte function. The practical part of the thesis aims to measure the properties of aprotic electrolytes: their conductivity, potential window and flashpoint. It also contains a review of the measurement results.
