The thesis analyses how the system of oil and fuel storage was created, and applied in Sweden during the Cold War. The investigation focuses on the period 1938-1998 and considers the vital role of fossil fuel during a period when Sweden declared neutrality and independence. This period also includes a phase of divestment of some of the state-owned stores. The project is partly based on original research in several archives including the Swedish Geological Survey, the War Archives of Sweden, the archive of the city of Stockholm, and relevant state agencies. Fuel was a means to security of supply, and how current policies interacted, as well as the extent to which it was perceived as a vital part of the nation’s current security politics. In particular, how the storage of oil, on a large scale, demanded adjustments of the physical Scandinavian bedrock, which in turn required new technology is examined. The study follows the forthcoming of both an organisation and a new set of knowledge illustrating how the practice of storing oil, in itself an unstable fluid changing characteristics over time, created a surrounding social network. The thesis also reviews the environmental awareness and ensuing concerns relating to the stores. The oil storage created a whole range of new specialists and experts, as well as academic fields, which all converged around the storage of oil. The long-term storage required regulations and monitoring, resulting in creation of new areas of expertise both within the companies obliged to store oil, and also within relevant state agencies. In addition, supervising authorities developed, typically governmental agencies, of which one was also assigned to dismantling the stores. The thesis discusses the political climate motivating the dismantling of the stores relating to contingency planning and civil defence, tracing the discourse until today when stores are now being re-activated.

Soil contamination by gasoline underground storage tanks is a critical environmental problem. The results herein show that in situ bioremediation using indigenous soil microorganisms is the method of choice. Five sites were selected for bioremediation based on the levels of benzene, toluene, ethylbenzene and xylene and the amount of total petroleum hydrocarbons in the soil. Bacteria capable of degrading these contaminants were selected from the contaminated sites and grown in 1,200 I mass cultures. These were added to the soil together with nutrients, water and air via PVC pipes.

La gestion thermique est un des moyens de réduction de la consommation spécifique d’un véhicule. Avec le réchauffement climatique, les normes de dépollution deviennent de plus en plus sévères et les constructeurs automobiles cherchent à améliorer le rendement des véhicules. Le but de ces travaux de recherche est de valoriser, par simulation numérique, les nouveaux systèmes de gestion thermique en fonction du cycle d’homologation et de la température ambiante.Un modèle de simulation 1-D du moteur et de ses circuits de refroidissement et de lubrification ont été développés en utilisant le logiciel GT-Suite. Quatre cycles d’homologation ont été choisis : NEDC, WLTC, AH et AU. De plus, un nouveau cycle a été proposé durant cette étude. Le bilan d’énergie effectué pendant les différentes phases des cycles souligne l’importance du stockage et de la récupération d’énergie.Le stockage d’énergie dans un volume eau et/ou d’huile abouti à l’amélioration de la montée en température des deux fluides. Plusieurs configurations ont été proposées comme, par exemple, un carter d’huile multifonctionnel.Ainsi, une réduction importante de la consommation en carburant est obtenue.La récupération de chaleur au sein des gaz d’échappement est ensuite mise en oeuvre. L’échangeur est caractérisé sur un banc d’essais puis modélisé. Le réchauffement indirect et direct d’huile abouti à une réduction importante des frottements et de la consommation. Une configuration est proposée afin de contrôler la température maximale de l’huile.Finalement, différentes stratégies comme : le type d’huile, l’isolation du moteur, une température de régulation plus élevée etc… ont été étudiées et valorisées. / Thermal management proved itself in improving the fuel efficiency of the engine. Nowadays, automotive companies tend to apply different strategies to answer the greenhouse severe laws. The PhD aim is to valorize and analyze the different thermal management strategies with numerical simulations over different driving cycles and ambient conditions. A 1-D simulation code of the engine and its hydraulic circuits were built using GT-Suite. Four known driving cycles were chosen: NEDC, WLTC, AH and AU. In addition, an in-house developed driving cycle was introduced. An energy balance made over the different stages of the driving cycles underlines the importance of the heat storage and the exhaust heat recovery strategies.Heat recovery was applied over the coolant and the oil at ambient temperatures of -7°C and 20°C. Hot coolant storage and hot oil storage led to improve the coolant and lubricant initial temperatures respectively. Different configurations (total of 7) were proposed and studied. A multifunctional oil sump was introduced. Important fuel consumption savings were obtained. Exhaust heat recovery was then valorized. Heat exchanger was characterized over experimental setup then added to the engine model. Indirect and direct heating of the lubricant as well as both strategies back to back were tested. Remarkable friction reduction and fuel savings were obtained. Special configuration was proposed to control the lubricant high temperature instead of the bypass on the exhaust line. The study ended by valorizing minor strategies as the oil’s grade influence, the engine insulation, high temperature set point …

The content of this thesis is the design layout and construction of the building of new fire station in South Moravian Region. It is an object split into two interconnected parts: administrative - two-storey, basementless garage for trucks - single-storey, basementless The object is used to perform the services of eight firefighters per shift and one full-time worker. Architecture was chosen so that the object is functionally meet the requirements of firefighters on duty at both organizational (work on PS) and at the operational (exit) procedure. The building is covered with a flat roof, attic walled building on the peripheral wall with white facade and symbols accentuating the purpose of the building. The inner workings of the object are designed to meet the performance demands of service 24ti - hour shifts. The building is brick, based on the footings and load distribution base. The roof structure is made of reinforced concrete load-bearing concrete slab with heat-waterproofing layers classical arrangement of layers. The building is insulated ETICS. This - the operational part is located on the 1st and 2nd floor of the south-western part of the building, single-storey garage built for trucks in the northeastern part.
