Dödsgott med käk i kistan : En GCMS- och FTIR-analys av kermik från ett vikingatida gravfält i Alsike hage, Alsike sn, Uppland

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.

Andlighet och religiositet på Fryshuset : en inblick i en senmodern och global förändringskontext

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".

Vårlamm eller dikoproduktion i Dalarna : fallstudie

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.

Utredning av potentiella hälsorisker i samband med slagg- och slaggvattenhantering vid Hedenverket, Karlstad

In this study potential health risks for employees in connection with handling of bottom ash and bottom ash water at a Municipal Waste Incineration (MWI) plant have been investigated. Air surrounding the bottom ash and the bottom ash water has been examined. MWI is one of the primary ways to manage solid household waste, and bottom ash is the main solid residue produced by the incineration process. Bottom ash constitutes about 15-20% of the original waste. The bottom ash is extinguished in a water bath (bottom ash water).The study was carried out in a MWI plant in Karlstad, Sweden.

Undersökningsmetodik för klorerade lösningsmedel i marken

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.

Är ekologiska slaktkycklingar sjukare än konventionella?

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.

Utvärdering av jetomrörning : En studie gällande utvärdering av omrörningssystem vid Ekeby reningsverk

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.

Nötkreaturens val av betesvegetation på naturliga betesmarker :

This study concerns the type of vegetation selected by cattle grazing on semi-natural pastures, and whether the selection depends on the nutrient content of the vegetation or on other factors. The study was carried out in three different semi-natural pastures in the Uppsala area during June, July and August in 2006. The three pastures were first surveyed, mapped out and divided into sub-areas with regard to the type of dominating vegetation. The vegetation types identified were: wet, mesic, dry, wooded, pasture with signs of former cultivation (arable). Within each vegetation type three 1x1 m sampling plots were laid out. The grazing behaviour of the cows was recorded in a behaviour study.

Perfluoroalkyl substances in Arctic birds : a comparison between glaucous gulls and black guillemots from Svalbard

Perfluoroalkyl substances (PFASs) are ubiquitous in the environment today and they have been detected even in remote areas such as the Arctic. PFASs can be transported by the atmosphere and ocean currents but the transport mechanism is not fully understood. PFASs may be harmful to organisms due to their persistence in the environment, bio-accumulation potential and toxicity. Studies have shown that PFASs can cause adverse effects on the metabolism as well as the endocrine- and reproduction systems in organisms. In this study, PFASs were investigated in glaucous gull (Larus hyperboreus) (n=5) and black guillemot (Cepphus grylle) (n=4) from Svalbard.

Butikschefers strategier kring hälsa och hälsoperspektiv : En studie inriktad på godis och läsk

Summary                                                               Overweight and obesity in Sweden and in the rest of the industrialized world continues to increase. This results in increased costs both to society and the healthcare system. Part of this development is the increasing consumption of sugar and that is what should be restricted to tackle this growing social problem. Part of the increased consumption of sugar in Sweden was the launch of pick and mix ingrocery stores.  This study aims to examine how store managers look at their public health responsibilities, and investigate how managers of grocery stores think about health and health aspects in general and about the sugar consumption in particular. Semi-structured "face to face" interviews was used to collect data and seven grocery store managers participated in the study.

Hur marknaden bedömer europeiska företagstillkännagivanden vid etablering i BRIC länder

The aim of this study is to examine how European companies? stock price is affected by an announcement about foreign direct investment in one of the BRIC countries. Another aim for the study is to examine if the market reacts differently to the three modes of entry methods in a given BRIC country and to examine if the market reacts differently to different European countries. The study also set out to answer if there were any effects of the three modes of entry that was visible a short time after the announcement. To answer and examine this, the authors used the event study approach. The study was conducted with a sample of 47 companies from France, Norway, Spain, Sweden and Germany.

Cooking banana farming system in rural Uganda : a comparison between agroforestry systems and non agroforestry systems

The demand for food, feed, fibre and fuel has increased in Uganda over the past 50 years due to population growth. Recurring extreme climate events such as drought and flooding, in combination with large-scale land degradation, have led to declining crop yields. Lack of equipment, money and socio-economic issues has contributed to low yields. However, the soils in Uganda have the potential to produce much higher yields than they do today. This study, which was carried out in April-June 2013 in Kkingo District, south-east Uganda, examined the effects of agroforestry on yield of cooking bananas in small-holder farming systems. Six farms practising agroforestry and six farms with no agroforestry, which were chosen in cooperation with the NGO Vi Agroforestry, were compared.

Outnyttjade resurser inom park- och naturvård

As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.

Indirekta effekter på marklavars abundans och diversitet vid ökad kvävehalt i marken : en jämförelse mellan opåverkad och lågintensivt brukad mark

Lichens are adapted to bright and sparse forests on oligotrophic ground. Due to a slow growth rate and high light demand lichens will suffer from competition in eutrophic environments. Therefore, lichens have disappeared from managed forests where the forest industry has increased the productivity. A reduced abundance of lichens will affect both biodiversity of the forest and the reindeer winter graze lands. It is important to understand how and for how long fertilization affects the abundance and diversity of lichens in order to protect lichen rich ecosystems. We have registered the biomass and number of lichen species in eight plots (four nitrogen rich and four nitrogen deficient) and compared fertilized Sami settlements with their oligotrophic surroundings in the nature reserves of Tjeggelvas.

Innovation och kreativitet i en hierarkisk miljö ? Malmö högskola - Medieteknik

Medieteknik är en avdelning på Malmö högskola som dagligen handskas med att vara en innovativ och utvecklande del i en större organisation. Något som skapar möjligheter, men även begränsningar. Högskolans krav, resulterar tillsammans med omvärldens föränderlighet i att avdelningen måste växla mellan struktur, planering, genomförande ? och ? utveckling, innovation av innehåll, utbud, pedagogik. Syftet med rapporten är att undersöka hur en innovativ och kreativ utvecklingsmiljö skapas och bevaras i en organisation/myndighet. Genom en enkätundersökning skapas det empiriska material som, tillsammans med studiet av högskolans villkor, samt förankring i den teoretiska referensramen besvarar den aktuella frågeställningen: Vilka förutsättningar kan påverka en avdelning att arbeta och agera innovativt inom ramen för den större organisationens styrning och krav? Slutsatsen är att Malmö högskola ställs inför en rad motstridiga krav som kräver jämvikt inom organisationen, för att arbetet på avdelningsnivå ska fungera.
