This paper deals with the connection between food and burial habits during the late Iron Age in present-day Sweden. The archaeological material used in the study consists of 16 potsherds from a burial site at Alsike hage, Alsike parish, in the province of Uppland in east-central Sweden. On these potsherds have been conducted FTIR- and GCMS-analyses, in order to see what types of food have been deposited in the burials. Furthermore, the result of the GCMS-analyses has been compared to contemporary material from both burial sites and settlement sites, in order to establish whether differences between the compared materials exist. The analyses show that there are differences between the material from burial sites compared with the material from settlement sites, but not any particular differences between the material from different burial sites.

Safe retrieval of nutrients from human excreta to fertilize crops in order to gain adequate yields will increase food security and sustainability in agriculture areas with nutrient-poor fields. Safe and nutritious food will meet the dietary needs of the individual which promotes public health and the ability of an active life. Human excreta should be considered as a resource instead of being assumed as waste. Human faeces and urine is excellent fertilizers which may close the nutrient loop if utilized properly. However, sanitation of the excreta is required to prevent disease transmission by reducing the content of gastrointestinal pathogens such as bacteria, viruses and parasites. The objective of this study was to in small scale evaluate the sanitation in a combined liquid compost and urea treatment by monitor the inactivation of bacteria and viruses at the combination three start temperatures, 45, 40 and 35 °C, and three additions of urea, 0.5, 0.75 and 1 % and reference, 0 % urea addition.

The aim of this study is to investigate the components of religion and spirituality in the specific context of "Fryshuset" ? a multicultural and glocal arena. Against the backdrop of contemporary researchers such as Heelas and Woodhead and their hypothesis about the "spiritual revolution" and a "new spirituality", as well as the postmodern discussion about "the return of God", this study discusses how religious change can be understood in the context of Fryshuset.The theoretical point of departure is taken in a hermeneutical method where Fleck´s theory about "thought-collective" and Gidden´s theory about the "duality of structure" are used in order to understand and describe the dialectical relationship between individual and social structure.The method used in this study is qualitative. The interviews are made of six individuals representing different social projects at Fryshuset.By analyzing the material from the field study through theories on religious change, three areas are identified:"The subjective turn"Religion and spiritualityA Cosmopolitan interpretation of life The result of this study is that the religiosity among the interviewed can be described through Taylor?s understanding of the "subjective turn".

This study investigates a farm in Dalarna which includes 16 ha of farmland and 1, 7 ha of pasture. The purpose is to find out if it is possible to start an animal production in Dalarna. The study is set only to compare spring lamb production with nurse cow production. There are two buildings on the farm that can be used for this purpose. One is an old cowshed, and the other is an unused silo for silage with a roof on top. Both of the buildings are compared to every alternative in the calculations.

With the climate change issues growing in importance on the social agenda, the field of urban masterplanning is of no exception when it comes to minimizing the carbon footprint in a variety of projects. The aim of this thesis has been to prepare the Carbon Critical Masterplanning tool, a software plugin for carbon dioxide emissions assessment developed by Atkins, to be used in Swedish conditions. The main targets were to improve the areas of the tool associated with energy conversion and renewable energy sources, and to test the tool in a real case. A planned construction of a new campus in Albano, Stockholm was chosen for the pilot study. A 3D model was built in the tool and the carbon footprint was calculated for a variety of combinations for energy supply to the future area.

Chlorinated solvent are volatile organic substances that can be harmful for humans and for the environment. Examples of common chlorinated solvents are perchloroethene, PCE, and trichloroethene, TCE. Chlorinated solvents appear as contaminants in soils primarily where they have been used as washing fluids in dry-cleaning facilities or as degreasers in metal industries. Chlorinated solvents are DNAPLs (dense non-aqueous phase liquids), which means that they are not easily dissolved in water and that they sink to the bottom of the aquifer. Adsorption to soils is low so chlorinated solvents are mobile in soils.

Fjärrvärmen utgör idag ungefär 12 % (48 TWh) av Sveriges totala energianvändning. Starka argument att använda fjärrvärme för att tillgodose bostäders och lokalers värmebehov är möjligheten att använda olika bränslen av skiftande pris och kvalitet, den goda verkningsgraden en centraliserad värmeanläggning erhåller samt fördelen med att kombinera produktionen av el och värme.Halmstad energi och miljö (HEM), förser Halmstad och närområdet med fjärrvärme och total mängd producerad energi uppgick 2009 till 596 GWh. Avfall och biobränsle utgör den största produktionsandelen men även industriell spillvärme samt mindre mängder olja och naturgas används för att framställa värme.Konkurrenssituationen för fjärrvärme är på många orter i det närmsta monopolistisk där en stor aktör äger hela marknaden. Det är viktigt att förbättra fjärrvärmesystemet för att i framtiden behålla dess konkurrenskraft. Följande rapport utreder och beskriver åtgärder för att göra ett redan befintligt fjärrvärmesystem mer effektivt.Utifrån möten med personal på HEM har tio punkter presenterats, vilka utvärderar olika delmoment i Halmstads fjärrvärmesystem.

For most pupils homework is a natural part of school and their education and there are several providers of homework assistance: the pupil's parents, sibblings, friends, Internet forums, hired private tutoring, non-profit organisations and at times even the pupil's school. This study has investigated the use of the school-based homework assistance programme at the Upper Secondary School of Psychology in Stockholm and why the programme is not more frequently used by its pupils. The school offers homework assistance two hours each Thursday afternoon, with at least two teachers being present to tender for the school's 127 pupils. The cost of the programme has been estimated to approximately 12 500 Swedish kronor per week. Through the main use of a questionnaire given to both the school's students and teachers, as well as an interview with the school's headmaster, this study will show that despite receiving the opportunity few pupils take part of the programme on a regular basis.

På grund av en ökad befolkningsmängd och nya tekniker som gör fler sjuka går att bota ställs nya krav på svensk sjukvård. Sjukvården måste möta de nya kraven med ett bättre effektivare resursanvändande och där till krävs nya förbättringsmetoder. Med influenser från industriell tillverkning har sjukvården omarbetat lean production för att skapa ett universellt förbättringsverktyg som lämpar sig för vårdorganisationer. Verktyget kallas lean healthcare och är omdiskuterat och dess effekter tvetydiga. Att undersöka om och hur värdeflöden i en akutmottagnings triage, som innebär en prioritering efter patienters allvarlighetsgrad, kan effektiviseras med hjälp av ett flödesorienterat arbetssätt som lean.

Femsjö is a small parish situated in Hylte municipality, Växjö diocese. The parish has a total area of 8230 ha of which 5000 ha are covered with forest. There have not been any large industries in the parish offering work opportunities for the inhabitants, so they have had to generate income from their land and the forest. Instead of going to the bank to get a bank loan the people of Femsjö parish went out in to the forest and harvested trees for timber and extra cash revenue. Production of pine tar and potash were two other ways that the residents of Femsjö parish could earn extra money for the household in order to keep starvation away.

A new build in the Swedish nuclear power system would entail increased re-quirements for the proposed repository, which is adapted after the reactors of today. With a fast reactor, capable of burning nuclear waste, operating in parallel with the light water reactors, the increased requirements on the repository could be reduced.In this thesis, simulations of a light water reactor and a fast reactor have been performed by using the Monte Carlo code Serpent to investigate the changes in the fuel inventory. The light water reactor in the study is a boiling water reactor and the fast reactor of the type sodium-cooled fast reactor and they have been used for three different operation scenarios.By studying the fuel composition and the results from the simulations of the three scenarios conclusions can be drawn. Conclusions regarding the change of the fuel inventory and decay heat in Clab as well as the interim storage facility and in the repository. Depending on the operation alternative the changes dif-fered significantly and especially regarding the mass of burned actinides for different fuels in the fast reactor.The lowest increase of fuel assemblies was meet when using 50 years old fuel with 20MWd/kg U burnout and 2,0 % enrichment for start up of the fast reactor and 30 years old fuel assemblies with 50MWd/kg U burnout and 4,7 % enrichment for the further operation of the reactor.The increase of the number of fuel assemblies was 3174, which is equivalent to 641tons of heavy metal.

In Sweden, the eutrophication of lakes, water courses and the coastal areas is considered the major threat to aquatic ecosystems and therefore actions taken to reduce the nutrient load to aquatic system including the Baltic Sea has high priority. There are many different sources of phosphorous and nitrogen and domestic wastewater is one contributing factor to the high load. Especially waste water from households that is not connected to municipal sewage treatment or a local small scale plant with appropriate nutrient removal efficiency is considered a problem. These types of households are quite common in rural areas in Sweden and in areas where summer houses has been converted to permanent living. Swedish legislation now permit the municipalities to decide in which areas within the municipality higher demands of the local small scale treatment facility should be met by the households (i.e.

Deposited waste material degrades within a short period in anaerobic environments. The methane gas that is formed provides a harmful contribute to the greenhouse effect, 23 times larger impact than carbon dioxide. It is therefore desirable to minimize the emissions of methane gas from landfills. This may be achieved by drain the landfill of gas. In this thesis the amount of produced methane gas at the landfill at Örebro has been calculated. Estimations have also been made of the amount of methane gas that might be produced in the landfill in the future.

Den ekologiska produktionen styrs av många olika lagar och regler som den konventionella produktionen inte behöver följa. Dessa regler kan ses som en välfärdsgaranti i den ekologiska slaktkycklingproduktionen då reglerna främst är skrivna för att kycklingarna ska kunna utföra sina naturliga beteenden i en passande miljö. Rastgårdar ska finnas till de ekologiska kycklingarna för att de ska få beta, få motion och få chansen att bygga upp sitt naturliga immunförsvar. I många fall ses rastgården som en positiv aspekt av den ekologiska produktionen, men det finns även problem relaterade till utevistelsen då exempelvis vilda djur kan lockas till slaktkycklingarna och på så vis stressa upp dem, smitta dem med parasiter och patogener eller äta upp dem. Det är vedertaget att den ekologiska produktionens dödlighet är högre än den konventionella produktionens på grund av rovdjuren och sjukdomarna och de ekologiska kycklingarna utsätts i många fall för fler smittorisker på grund av utevistelsen.

Biogas is a renewable energy produced through anaerobic digestion, which means that organic matter is degraded by microorganisms under anaerobic conditions. The produced biogas can then be used for cogeneration, electricity, heat or upgraded to vehicle gas. Eskilstuna Energy & Environment AB has four digesters at Ekeby water sewage treatment plant, Eskilstuna. One of the biogas reactor (RK4) is equipped with a jet-mixing system while the remaining digester uses top-mixing. The mixing system is an important parameter to achieve optimum operating conditions for the process regarding gas production and degree of digestion.
