Fast pyrolysis is a method for converting biomass into three energy rich products: char, gas and bio-oil, where the latter is most interesting.  Pyrolysis is an endothermic process where biomass is heated in an anaerobic environment and, with the right operating conditions, up to 80 %wt bio-oil can be extracted. Key parameters for fast pyrolysis are: stable reactor temperature (~500°C), short residue time for gas in the reactor (<2 s) and a very high heating rate for the biomass. Today there are several different process solutions for fast pyrolysis, where fluidized beds and rotating cones are most developed. Bio-oil has compared to fossil oil: lower heating value, low pH and also polymerizes with time. Because of this upgrading is desirable for increasing competitiveness.

Tuberculosis is one of many infectious diseases in the world and is responsible for a large number of human deaths each year. The cause is Mycobacterium ssp included in the tuberculosis-complex, there among Mycobacterium bovis and Mycobacterium tuberculosis. Infection with M. bovis causes bovine tuberculosis in cattle which in 90 % has a pulmonary location. Humans are infected mainly by milk from infected cows but also by close contact with coughing animals or by eating raw meat.

Vid tillverkningsprocesser av nya komponenter omvandlas material till antingen en produkt eller restprodukt, varpå restprodukterna hanteras som antingen biprodukt eller avfall. Oavsett karaktärisering är den genererade beståndsdelen föremål för någon form av fortsatt behandling. Vid frågan om restprodukt kan det handla om en åtgärd för avfallshantering, då substanserna saknar funktionella egenskaper för fortsatt användning. Det kan också vara så att avfallet besitter ett kommersiellt värde och kan återanvändas som en råvara i andra anläggnings- och tillverkningsprocesser eller i form av bränsle. Oavsett tillämpad åtgärd krävs tydlig lagstiftning som främjar en gynnsam utveckling och förhindrar uppkomsten av skadliga föroreningar.

By examine cremated remains from graves dated to late Iron Age I wanted to find out what sorts of animals were placed in the graves. But also to see if the animal sacrifices had any connection to the Old Norse religion. The osteological material that were analysed were from both cremated humans and animals and had been dated to Viking Age. The material is from burial ground 59 at Laxare, Boge parish on Gotland. In addition to the human remains, the material contains bones from horse, cattle, sheep/goat, pig, dog, cat, bear, birds and fish.

Environmental problems are accelerating with energy consumption and the release of greenhouse gases as the major issues. This affects landscape planning mostly through environmentally hazardous transportation and heating of buildings. In environmental work, the term "Sustainable development" is often used. This term was coined in the Bruntland report in 1987. A number of frameworks have been developed to clarify the term and to remind the user about relevant aspects of sustainability.

BackgroundThis paper is based on an issue raised by the organization Energigas Sverige, which together with the Ministry of Finance has posed the question about the fiscal impact of an increase in biogas production. Since the fiscal effects of an increased biogas production are both positive and negative, due to reduced use of fossil fuels, we want to investigate this further.PurposeThe purpose is to describe and explain the obtained fiscal impacts of an increased biogas production and based on our problem: ?What are the obtained fiscal effects caused by an increase in biogas production?? we could see the following fiscal effects: positive impact on employment, increased revenues of social security contributions and income taxes, reduced unemployment costs and reduced tax revenues on fossil fuels. These effects are summarized in a negative tax revenue of 2,6 billion SEK. Along the summarized negative effect we also accepted one of the two prepared hypotheses, which stated that an increase in biogas production leads to a negative fiscal impact. Design/Methodology/ApproachWe have chosen to work from an Anglo-Saxon scientific tradition and furthermore, we have a positivistic approach when we want to explain the relationship between cause and effect of an increase in biogas production and the following fiscal impacts.

I mer än hälften av Sveriges sjöar innehåller gädda en kvicksilverhalt som övergår Food and Agriculture Organization?s (FAO) rekommendationer. Det kvicksilver som finns lagrat i svensk skogsmark är ett resultat av antropogent nedfall. Studier visar att kvicksilver utlakas vid skogsbruksåtgärder på hela skogsmarken som en följd av förhöjd rörlighet av dissolved organic carbon (DOC). En ökad metylering av kvicksilver sker vid vattenmättade, syrefattiga förhållanden där det finns tillgång till organiskt material.

The calculations in this thesis are evaluating the profit as a consequence from treating young stands of pine in Sweden with birch bark extract, BBE. Treatment is to be done with the object to lower or fully reduce the moose browsing on pine. The study is made in three versions. The results from each version separately will follow below. Version I.: The size of the moose population is in no way affected by the reduced resources of food as a consequence of large scale treatment with BBE on pine. Results show profit at a 3 percent level of interest with the exception of treatment program with more than 4 treatments all together and with the exception of Västerbottens Län with an early first treatment. Version II.: The population of moose decrease from 10 to 5 individuals per 1000 ha as a consequence from large scale treatment with BBE on young pine stands.

The development within the textile industry is always ongoing with development of new andbetter textiles, which often mean the use of non-natural materials like polyester. This doesn?t lineup with the work shared around the world against an improved environment, so the idea came touse a form of linen fibers instead of polyester as the reinforcing material together with cotton.The idea was to use flax, linen of low quality, which is seen as a waste product and garbage inthe production of high quality linen and flax seed oil. This flax of low quality needs to beseparated before it can be used in cotton spinning machines. Fireball 2 is just that, a process toseparate flax fibers through the treatment of a technique called electrohydraulic discharge.The thesis works goal is to evaluate the Fireball 2 process ability to separate flax fiber.

This paper deals with a taphonomic study of contexts with osteological material of dog (C. familiaris L.) from the Mesolithic and Neolithic of Sweden and Zealand, Denmark. The general aim is to develop and test a method to try to understand the activity behind and define specific archaeological structures. My questions also regards to wether a taphonomic analysis of the material could be used to identify treatments as wrapping and contraction of the dogs, but also dismembering and other preparations of the body. The study focuses on the relation between the space of decomposition, disarti-culation of the joints, evidence of wall effect, cutmarks, weathering and signs of postdepositional arrangements.The analysis is based on contexts from the materials Hornborgasjön, Vedbæk, Skateholm I and II, Sjöholmen, Ertebølle, Bökeberg, Bredasten, Löddesborg, Bergsvägen and Röekillorna, dating from early Maglemose culture to Neolithic Battle axe culture.The analysis shows that a closer study of taphonomic processes can be used to identify different structures as graves, offerings, religious and non religious contexts or parts of animals, probably put into the ground as waste.

Vår allt mer globaliserade värld har medfört att alltfler svenska företag internationaliserar sin verksamhet till mer avlägsna områden. Ett av dessa svenska företag som nu står inför sin första utlandsexpansion är den svenska snabbmatskedjan Max AB. Max har valt att börja sin expansion i Saudiarabien, ett land långt ifrån Sverige, inte bara i termer av geografiskt avstånd utan även kulturellt avstånd. De kulturella skillnaderna som Max möter kan komma att påverka verksamheten och leda till att vissa anpassningar måste genomföras för en framgångsrik etablering. Uppsatsen undersöker det rådande förhållandet för snabbmatsbranschen i Saudiarabien och visar vilka anpassningar internationella snabbmatskedjor bör eller måste göra på grund av de kulturella skillnaderna de möter.

This BSc thesis is an introductory step to the collaboration between the Swedish zoo Skansen and Kenya Wildlife Service (KWS). It constitutes of an inventory of the Nairobi Animal Orphanage (AO), a facility that cares for injured and abandoned wildlife species in Kenya. Through the cooperation with Skansen, the KWS will improve their management of the AO. The aim of the inventory and BSc theses is to evaluate the management of black-backed jackal (Canis mesomelas), lion (Panthera leo) and patas monkey (Erythrocebus patas) regarding their biological needs. The general enclosures, routines and feeding at the AO are also evaluated since they have a great influence on the management of captive animals.
