Miljöpåverkansbedömning vid tillverkning av etanol från cellulosabaserade råvaror : ekologisk gård självförsörjande med drivmedel
Fuel produced from renewable resources is of big interest. In this project the difference between a few different renewable materials are compared on the matter of environmental load when ethanol is produced. The renewable materials that are compared are Salix, straw and reed canary-grass (rörflen). The cellulose in the material is cut down to small pieces and then hydrolysed so that the sugar from the cellulose can be fermented into ethanol.
Tha amount of ethanols that is studied in this work is the smount of ethanol needed to cultivate 1000 ha. The functional unit in the report is 1000 ha.
Gör skolbibliotekarien någon skillnad? En studie av skolbibliotekariens betydelse för unga elevers läs- och språkutveckling
The purpose of this study is to investigate? how a professional librarian can support the work with pupils, age six to twelve years, in their reading and linguistic development? how the conditions at the school have to be for this to become possible? what kind of attitudes the teachers have, and how they relate to the impact of a librarian for the pupils reading and linguistic development.The methods used are analyses of steering documents concerning school libraries and analyses of the means of the local school culture. The latter has been carried out by literature studies and through interviews of eight teachers and two school librarians. The result of the interviews showed a limited insight into how a professional librarian can support and assist teachers and pupils in the work with reading and linguistic development. They also showed the influence of existing traditions and local school culture for the use of a librarian?s services, and also how all the teachers, once they have become used to the services a librarian can provide, now find their support invaluable.
Geokemin inom osorterade cirklar : Analys av tungmetallers distribution inom jordprofiler tagna från Abiskoområdet, nordvästra Sverige
The Arctic region appears as a pristine remote environment, yet there is increasing evidence that it is greatly impacted by pollution such as lead (Pb) and mercury (Hg). In this environment deposition of Hg has increased threefold since the last industrial revolution. In this study five cryosolic soil profiles within non-sorted circles (NSC) in the Abisko region, northwest of Sweden, has been analyzed to improve our understanding regarding how pollutants are distributed within such type of soil. The soil samples have been analyzed with the use of X-ray fluorescence analysis (XRF), for the measurements of the total concentrations of e.g. lead (Pb) and zirconium (Zr).
Hydraulisk och termisk grundvattenmodellering av ett geoenergilager i Stockholmsåsen
Geothermal energy can be extracted from an aquifer, where the groundwater is used as heatexchange medium while heat and cold are stored in the surrounding material in the aquiferand to some extent in the groundwater. Application of aquifer storage for the use ofgeothermal energy is mainly used in large scale facilities and is limited to sites with suitableaquifers in the form of ridges, sandstone and limestone aquifers.Löwenströmska hospital in the municipality of Upplands Väsby, north of Stockholm, islocated nearby the northern part of the Stockholm esker. This means that it can be profitableand environmentally beneficial for the hospital to examine the possibilities of aquifer storagein the esker material next to its property.The purpose of this master thesis has been to investigate if geothermal energy storage with aseasonal storage of heat and cold can be applied within Löwenströmska hospital?s propertyarea using groundwater modeling. A hydraulic groundwater model was constructed inMODFLOW based on a simplified conceptual model of the groundwater system.
Dubbelprövningsförbudet avseende skattetillägg och skattebrott : - en utredning av införandet av regeringens förslag gällande en spärreglering samt ett samlat sanktionsförfarande ur ett rättssäkerhetsperspektiv
A tax penalty is an administrative penalty and is levied when the tax obligated provides false information for the guidance of their own taxation. Further can the taxpayer also be punished for tax evasion for the same false reporting. However, this is contrary to the European Convention that we should not be tried or punished twice for the same crime. The Supreme Court has through practice from 2013 ruled that the right not to be punished twice for the same offense shall include the system in force concerning tax and tax offenses. The Supreme Court has by this judgment determined that the system of penalty and tax evasion is not compatible with the dual test ban.In the light of the judgment the Government submitted in November 2014 a draft to the council regarding double test ban regarding penalty and tax evasion.
Varför lyckas inte alla? : En studie på Hantverksprogrammet Frisör och Florist om skillnader mellan hög- och lågpresterande elever.
Our purpose with this study was to investigate whether there was any difference between high and low performing students from selected aspects such as choice of studies, achievement, self-image, motivation, confidence and career choices.A training professional in today's schools requires knowledge of how young people think about their lives for us to help students develop both high-and low-performing students. Students have different conditions, but no matter good or bad conditions, each individual pupil must be allowed to develop.The concepts used in the study are of study, self-image, motivation, achievement in the future and career choices. In the background, describes these concepts through literature study. The method we have used was semi-structured interviews. Which means a fixed structure, but with room for follow-up questions.The results of our study indicate that there were clear differences between high-and low-performing students.
Framgångsfaktorer inom Wallenbergsfären
AbstractThe purpose for this study has been to discover and reveal what exactly it is that have made the Wallenberg family so successful in the Swedish business world for more than 150 years. We have narrowed our research by limit it to only find and concern the specific features of the Wallenberg family and not their entire corporate group. There is no research made before regarding this matter, as far as we could see, which is one of the reasons to why we find this study relevant. In order to answer our question we have chosen to use a qualitative approach in which we have interviewed three people. These three people all have deep and thorough insight in the Wallenberg family.
Produktivitet och lönsamhet vid skogsbränsleuttag längs skogsbilvägar :
With an increased demand for biomass based energy and with development of better technique harvest biomass, new possibilities open up. With the possibility to combine traditional cleaning of road?s right of way with biomass harvesting, the work of suppressing tree vegetation could become profitable or at least decrease the road maintenance cost. However, knowledge about productivity and profitability in mechanical biomass harvesting in roads? right of ways are still limited.
En plattform för det fria ordet En studie om hanteringen av extremism vid fyra svenska universitet
This master thesis? purpose is to examine the role of Swedish universities in the prevention of extremism and terrorism. Depending on how the universities look upon their role in preventing extremism and promoting democracy among their students, extremism can either flourish or be restrained in the higher learning environment. An unclear standpoint against extremism from the universities side could make it possible for extremism to prosper at the universities, and students with extremist opinions may be radicalized and recruited to extremist organizations and terrorism. What are the universities standpoints in the matter whether universities should promote democracy and prevent and restrain extremism and the recruitment of students to extremist organizations? During the study I have mainly been using primary material in the shape of semi structured interviews with predecessors of four Swedish universities.
Downward migration and transfer to plants of radiocaesium in Scottish soil profiles : a comparison with earlier studies
Following the accident at the nuclear power plant in Chernobyl in 1986, great volumes of137Cs were distributed over large parts of the former Soviet Union and Europe. Over Scotland,radiocaesium was deposited as wet deposition. Due to the relatively long physical half-life of30 years, there are still measurable activity concentrations in the natural environment. Thisstudy was made on two organic soils, Knockandy Hill and Rora Moss, situated in the easternpart of the central highlands of Scotland. At these two sites, studies on migration and transferbetween soil and plants were conducted.

Inkludering kontra utanförskap inom Idrott & hälsa : En kvalitativ studie gällande hur elever med funktionsnedsättning upplever ämnet
The subject-matter of the following essay is to investigate the relationship between what is commonly called Deep Ecology or Biocentric Philosophy, as articulated by the co-founder of the Deep Ecology Movement, Arne Naess, and later proponents of the biocentric school of environmentalist thought. I contrast Naess? concept of Self-realization as founded in his Ecosophy T to the ideas of american conservationist and co-founder of the radical green movement Earth First! Dave Foreman, and to the controversial finnish environmentalist and ecofascist Pentti Linkola?s ideological agenda of population-reduction respectively.According to some critics of the movement, especially the social ecologist Murray Bookchin and French liberal philosopher Luc Ferry, the Deep Ecology ideology is essentially misanthropic and totalitarian in structure. A central idea among deep ecologists is that ecosystems and natural entities have intrinsic value in themselves, even outside a human social context. This idea is thought of among deep ecologists to create a philosophically sound basis for counteracting the environmental global crisis.
Energianalys av hygieniseringssystem : jämförelse av befintlig pastörisering med integrerad termofil hygienisering på Kungsängens gårds biogasanläggning i Uppsala
The biogas plant Kungsängens gård, owned by Uppsala Vatten och Avfall AB, produces biogas and biomanure from organic household waste, food processing waste and slaughterhouse waste. In year 2012, 4.4 million Nm3 of biogas were produced from 25 200 tons of waste. Before digestion all substrate is sanitized by pasteurization at 70°C in order to kill pathogens. Another method, integrated thermophilic sanitation (ITS), is of interest in order to decrease the energy demand. The method implies that the substrate is sanitized during ten hours in the digestion chamber, where the temperature is 52°C.
Om att kreativt charma B2B
Previous research has recognized that advertising creativity can result in positive signaling effects for consumers, thus proving creativity to be a useful tool and not a wasteful effort within marketing. However, research within this matter has only lightly touched upon the outcome of signaling effects within a business-to-business context. Since other implications prevail within a B2B market - for instance the professional position in which individuals act, the existence of buying centers, and the heavy weight placed on most decisions - the conception and influence of advertising creativity may be altered. This paper aims to give an overview of whether increased advertising creativity results in positive signaling effects among individuals employed within a B2B context. Furthermore, the paper aspires to examine the potential influence of aspects prevailing within B2B markets, such as the need for contemplating the desires of numerous individuals involved, on the outcome of advertising creativity.
Den kvantandliga diskursen : En undersökning av nyandlighetens möte med kvantfysiken
This paper aims to describe and elaborate on a recent discursive change within the new-age movement. Since the seventies and the publishing of speculative popular science books like The Tao of Physics by Fritjof Capra and The self-aware Universe by Amit Goswami, the idea that quantum physics resonates with spirituality has become the topic of hundreds of books and movies.The quantum-spiritual discourse has three distinct ways to approach quantum physics in its discussion on spirituality: The parallelistic approach which emphasizes the similarities between eastern philosophies and modern physics, the monistic-idealistic approach which tells us that mind is the foundation of matter and the scientific spiritual approach which tries to explain spiritual claims scientifically. In the quantum-spiritual discourse, quantum physical phenomena (e.g. non-locality and entanglement) are being called upon to validate metaphysical statements. The primary assumption of the discourse is that the shift of paradigm due to the establishment of modern physics also is a shift of paradigm of spirituality.With the object to examine the common claims made in the discourse, cross-references between spiritual arguments and facts of quantum physics are being made.
