This report presents an investigation and a new design of Habo Ullspinneris old industrial premises. It is based on the owners visions and wishes, two questionnaires and also considering of the historical value.Habo Ullspinneri was founded in 1882 by Frans August Johansson and was moved to the location it has today, near Hökån in Habo, three years later. The electricity that the machines in the industry needed was extracted from the small river that is placed under the building. In 1960 there was a fire and the result became the end of the industrial activity that had taken place in the building.There is no steady activity in the building at the moment. It is nowadays temporarily used as an agriculture museum and as a store room.

This thesis investigates if a system for small scale electricity production located in anurban environment can be profitable. The work has been divided up into two parts,one extensive literature study and one case study. The purpose of the literature studywas to investigate the area, resulting in a choice of which technology to be studied indepth in a case study.In the case study a system containing small scale wind turbines and photovoltaicsmounted on Gränby Centrums roof was examined. From data containing wind power,wind direction and total irradiation, possible production from a system weresimulated. Three products of each technology were examined in the simulations.From the simulated production an economic analysis was carried out, this toinvestigate if a system is profitable.

The postindustrial market increasingly demands service infused products to add more value to the customer in order to be competitive. Much research regarding digitalized services indicates that companies have to be innovative in order to compete on the market. However, companies within different industries face different challenges with digital service development. This study has been conducted because there are little known about the opportunities and the challenges different industries faces with a globalized market. Our research question is what the challenges are and what opportunities does strategic digital service development entails for companies.

Telekombranschen har de senaste decennierna upplevt en stark tillväxt, framförallt i urbana områden och västvärlden. Nu när denna tillväxt även sker i utvecklingsländer och dess landsbygd, söks det efter nya sätt att försörja basstationer som ej är kopplade till elnätet med energi. Syftet med detta examensarbete är att studera och analysera framtida hållbara energilösningar för basstationer inom telekombranschen.Detta görs genom att kartlägga alternativ, analysera vilka hinder och möjligheter som finns samt undersöka vilka kompetenser som krävs för en vidare utveckling. Arbetet har framförallt baserats på intervjuer av aktörer i telekombranschen samt litteraturstudier.Studien visar att de tekniker som i framtiden har störst potential att ersätta dieselgeneratorerna idag är solceller samt småskalig vindkraft. För att denna utveckling skall ske krävs det innovationer och nya sätt att implementera energisystem med basstationer.

One of the most common ways to produce heat and electricity in Europe today is by the incineration of waste or combustion of coal. These materials can be very sulfurous and during combustion sulfur dioxide is produced. This is an environmental and health related toxic substance which is why power plants have strict regulations on removing it from the flue gas. Sulfur dioxide is removed from the flue gas by adding a limestone reagent. The sulfur dioxide reacts with the limestone and the synthetic product obtained is ?Flue Gas Desulfurization gypsum?.

The spatial population structure of the saprotrophic basidiomycete Tulostoma brumale was investigated at a site in south eastern Sweden. Sporocarps were mapped and collected, and somatic incompatibility tests between mycelial cultures cultivated from the sporocarps were used to identify genets. Calculations of the size and numbers of genets and their distribution were performed. The spatial distribution of the tested sporocarps and the identified genets are presented graphically in a grid. The total number of identified genets within the investigated area (1210 m2) was 27 based on 48 tested sporocarps.

This thesis investigates if a system for small scale electricity production located in anurban environment can be profitable. The work has been divided up into two parts,one extensive literature study and one case study. The purpose of the literature studywas to investigate the area, resulting in a choice of which technology to be studied indepth in a case study.In the case study a system containing small scale wind turbines and photovoltaicsmounted on Gränby Centrums roof was examined. From data containing wind power,wind direction and total irradiation, possible production from a system weresimulated. Three products of each technology were examined in the simulations.From the simulated production an economic analysis was carried out, this toinvestigate if a system is profitable.

The goal of this master thesis project was to develop computer models of some plausiblepretreatment techniques and to assess the potential benefits/costs of using pretreatment andanaerobic digestion for waste management of organic waste from a system perspective. Forthis purpose a computer program called ORWARE has been used. ORWARE (organic wasteresearch) is a program for making life cycle assessments of waste management. As the mainpart of the project work the ORWARE system has been provided with three new models ofpretreatment techniques. The additions consist of: One model of pretreatment with ultrasound,one model of thermal hydrolysis and one model of a screw press.

In this thesis I have decided to take a closer look into my own ?backyard?. A river that runs through my hometown, Akureyri, has been a thorn in some people?s side. Glerá river has taken lives but it has also given the town possibilities to develop.

An analysis of a specific application of anaerobic wastewater treatment at a pulp and board mill, Stora Enso Skoghall, was carried out. A literature study was done and effluent wastewater from CTMP pulp production was analyzed. The analysis consisted of a broad constituent analysis and an anaerobic treatment trial. Results from these test where used to calculate the treatment effectiveness and resulting energy potential at the mill.The literature study and constituent analysis showed that toxicity of the water to be treated, due to wood extractives and sulphur content, was of concern. Detoxification chemicals targeting these constituents where used in the anaerobic treatment trial.

Ad Astra är en cirkushall, högt beläget på en skogsbeklädd kulle ca 10 minuter från Alby centrum. Här samlas hela Cirkus Cirkörs verksamhet under ett tak: elever, lärare, administration och besökare.Promenadvägen från Albys tunnelbana leder fram till ett torg med den nya byggnaden som fond. Ett strikt grid av 58 stålpelare definierar ett uterum på byggnadens tak som sluttar upp mot en kopparkub bland träden. Här skapas möjligheter till allt från utomhusföreställningar till picknick i ett landskap som subtilt smälter samman med den bakomliggande skogen. Gränsen mellan natur och struktur suddas ut samtidigt som taket ger en oöverträffad utsikt över Alby och Albysjön.Internt är byggnaden tvådelad med en publik, öppen del och en sluten,flexibel hallösning.

This paper examines the power producing dams along the Ume-river as an integral part of and a result from the urbanization process in Sweden during industrial capitalism. The aim of the paper is to contribute to the knowledge of the urbanization process in Sweden in general and of its traces along the Ume river in the county of Västerbotten in particular. The paper applies the theory of concentrated urbanization and extended urbanization put forward by Neil Brenner and Christian Schmid (2015) and argues that the building of power producing dams along the Ume-river is part of an extended urbanization process. This becomes particularly evident when examining the vast physical structures that is the dams, situated in an otherwise remote and sparsely populated area. These vast physical structures are also very well connected to a nation wide electric grid that has connections to bordering countries as well.

The Swedish Parliament has decided to increase the share of electricity produced by wind power. The same parliament has decided that the Sami have the right to herd reindeer over 50% of the country's land area. In this literature review the potential impact wind power development and associated infrastructure may have on reindeer husbandry conditions are examined. The unique physiology of the reindeer enables it to live out of grazing in the arctic climate in the north of Sweden. For reindeer husbandry to be long-term productive and sustainable, it is important that there is enough land for grazing. The research available on how reindeer are disturbed by human activities such as roads, mines, hikers, etc., clearly indicates that the reindeer avoids areas close to such disturbance.

Long time-series of pressure measurements often have high quality because the early instrumentsare more or less the same as the modern ones. A time-series from Lund consisting of three dailymeasurements from 1780-1997 has been homogenised and is therefore suitable for analysingpossible influences of the enhanced greenhouse effect. According to a two-layer model of theatmosphere one finds a shift in the frequency of baroclinic instability due to an increasedtemperature gradient caused by the increasing CO2. Baroclinic instability over the Atlantic Oceanis the main cause for frontal zone production, causing cyclonic activity over the southern part ofScandinavia. Changes to the baroclinic instability would therefore be traceable in the time seriesfrom Lund.
