“There is an overconsumption in the Swedish society that affects all living and contributes with consequences for all. How does this affect us humans? How does it affect society and what consequences become visible? Today the main focus is on the environment and climate changes where the government and the media are responsible for what is being published. The focus is the entire population but is the government and the media doing a good job to reach out to everyone of its inhabitants? To get a first point of view of the situation we have chosen a subculture to investigate - a social movement, Extinction Rebellion. They are making headlines all over the world with their radical actions which both informs and scares the population. Our study will have its starting point in the theories of Zygmunt Bauman - The consumer society, Bert Klandermans & Jacqueline van Stekelenburg - Social movements and Richard Jenkins - Social identity. By collecting empirical research by qualitative interviews, we would like to find an understanding that can explain why some people choose to deviate from the norm to act against society for the environment. The result indicate that people would like to change the society and that there is a genuine fear that is connected to the consumer society and its consequences. These consequences are the motivation for people to join a social movement, such as Extinction Rebellion.” / Det finns en överkonsumtion inom det svenska samhället som påverkar allt levande och bidrar med konsekvenser för alla. Hur påverkas människan? Hur påverkas samhället och vilka konsekvenser blir synliga? Det är idag stort fokus på miljön och klimatförändringar där staten och media väljer vad som publiceras. Deras inriktning blir mot hela befolkningen, men lyckas staten och media nå ut till alla invånare? För att få en inblick i hur situationen ser ut har vi valt att granska en subkultur - en social rörelse, Extinction Rebellion, som försöker skapa rubriker runt om i världen genom radikala aktioner som både informerar och skrämmer upp befolkningen. Studien har sin utgångspunkt i Zygmunt Baumans - konsumtionssamhället, Bert Klandermans & Jacqueline van Stekelenburg - sociala rörelser samt Richard Jenkins - social identitet. Metoden som används är kvalitativa intervjuer som söker en förståelse för att förklarar varför vissa människor aktivt väljer att avvika från normer för att ta ställning mot samhället för miljöns skull. Resultatet pekar på att individer har en vilja att förändra samhället samt en genuin rädsla för det senmoderna konsumtionssamhällets konsekvenser. Dessa konsekvenser blir en faktor som motiverar människor till att gå med i en social rörelse som Extinction Rebellion.

The present study used auditory fear conditioning to assess the impact of repeated binge-like episodes of alcohol exposure during adolescence on conditioned fear in adulthood. Male and female Long-Evans rats were subjected to adolescent intermittent ethanol (AIE) exposure by vapor inhalation between post-natal day 28 and 44. After aging into adulthood, rats then underwent fear conditioning by exposure to a series of tone-shock pairings. This was followed by cued-tone extinction training, and then testing of fear recovery. In male rats, AIE exposure enhanced conditioned freezing but did not alter the time-course of extinction of cued-tone freezing. During subsequent assessment of fear recovery, AIE exposed rats exhibited less freezing during contextual fear renewal, but greater freezing during extinction recall and spontaneous recovery. Compared to males, female rats exhibited significantly lower levels of freezing during fear conditioning, more rapid extinction of freezing behavior, and significantly lower levels of freezing during the tests of fear recovery. Unlike males that were all classified as high conditioners; female rats could be parsed into either a high or low conditioning group. However, irrespective of their level of conditioned freezing, both the high and low conditioning groups of female rats exhibited rapid extinction of conditioned freezing behavior and comparatively low levels of freezing in tests of fear recovery. Regardless of group classification, AIE had no effect on freezing behavior in female rats during acquisition, extinction, or fear recovery. Lastly, exposure of male rats to the mGlu5 positive allosteric modulator CDPPB prevented AIE-induced alterations in freezing. Taken together, these observations demonstrate sex-specific changes in conditioned fear behaviors that are reversible by pharmacological interventions that target mGlu5 receptor activation.

Various physical mechanisms that affect radiowave propagation at millimetre wavelengths are considered. Current modelling weaknesses are highlighted and new improved models or more appropriate modelling approaches are suggested. Interference and resonance phenomena in the scattering of spherical ice and water particles are reviewed. The long standing problem of the numerous resonances observed in the scattering diagrams of dielectric spheres is answered. The spatial structure and the physical characteristics of non-precipitable ice and water clouds are reviewed. Extinction and back scattering calculations for a wide variety of cloud models over the entire millimetre frequency spectrum are given. Multiple scattering and the effects of super-large drops in clouds are also dealt with. The potential of a spaceborne instrument in deducing information about the vertical structure of various cloud types is examined. Attenuation and reflectivity profiles resulting from various cloud types are calculated for a nadir pointing fixed beam millimetre wave radar operating at 94 GHz. The physics and application of the equation of radiative transfer to millimetre wave propagation in the earth's atmosphere are given and also is the solution of this equation for a typical millimetre wave remote sensing application. The theory of gaseous absorption at millimetre wavelengths is presented and an improved modelling approach is proposed for the calculation of the absorption and dispersion spectra of atmospheric gases. The effects of trace gases on communication systems operating at high altitudes are for the first time reported. Finally the use of the 60 GHz oxygen absorption band for top-side air traffic control/navigation and broadband transmission purposes is studied.

One of the challenges facing engineers is to provide clean, sustainable, affordable and reliable electricity. One of the major pollutants associated with coal combustion is CO2. A proposed technology for efficiently capturing CO2 while producing electricity is pressurized oxy-combustion (POC). The first objective of this work is to design, build and demonstrate an exhaust system for a 20 atmosphere oxy-coal combustor. The second objective of this work is to design and build mounts for a two-color laser extinction method in the POC. The POC reactor enables the development of three key technologies: a coal dry-feed system, a high pressure burner, and an ash management system. This work focuses on cooling the flue gas by means of a spray quench and heat exchanger; controlling the reactor pressure and removing ash from the flue gas. Designs and models of each component in the exhaust systems are presented. Methods to test and assemble each system are also discussed. The spray quench flow rate was measured as a function of pump pressure. Theoretical models for the required amount of water in the spray quench, the flue gas composition, the length and number of tubes in the heat exchanger, and the cyclone collection efficiency are presented. The combined exhaust system is assembled and ready to be tested once issues involving the control system and burner are resolved.

The developing knowledge of life sciences is at the crux of Margaret Atwood's Oryx and Crake as she examines human promise gone awry in a near-future dystopia. This thesis examines aspects of posthumanism, ecocriticism, and feminism in the novel's scientific, cultural, and environmental projections. Through the trope of extinction, Atwood's text foregrounds the effects of human exceptionalism and instrumentalism in relation to the natural world, and engenders an analysis of human identity through its biological and cultural aspects. Extinction thus serves as a metaphor for both human development and human excesses, redefining the idea of human within the context of vulnerable species. Oryx and Crake reveals humanity's organic connections with non-human others through interspecies gene-splicing and the ensuing hybridity. In this perspective, Atwood's text provides a dialogue on humankind's alienation from the natural world and synchronic connections to the animal other, and poses timely questions for twenty-first century consumerism, globalism, and humanist approaches to nature. The loss of balance provoked by the apocalyptic situation in Oryx and Crake challenges commonplace attitudes toward beneficial progress. This imbalance signals the need for a new narrative: A consilient reimagining of humanity's role on earth as an integrated organism rather than an intellectual singularity.
