Albys skärvor : Lipid- och morfologisk analys av tidigneolitisk keramik från Öland

In this essay, Neolithic potsherds from Alby, Öland has been examined. The purpose was to investigate the connection between the lipid residues and the vessel shapes and ornament. To solve the attempt lipid and morphological analyses were executed. The lipid analysis revealed traces of different food residues and the morphological method showed various shapes and decors. The result indicates that the Alby ceramics has been used for cooking/storage of different fish and meat dishes, as well as vegetables and that the vegetables doesn?t derive of cereals..

Medborgarförslag - ett sätt att stärka demokratin? En ideologianalys med kommunalt fokus

This thesis aims at analysing conflicts between different ideals of democracy, using the example of a newly implemented citizen´s initiative reform. This reform gives citizens the right to make policy proposals to Swedish municipal councils. The proposals are to be handled in the same way as proposals from the municipal council members. An ideology analysis of various government documents as well as of an official state study (SOU) is carried out to identify and discuss the ideals of democracy that underpin the reform. The analysis is based on participatory democracy and electoral democracy theory and Arnstein's Eight Rungs on the Ladder of Citizen Participation is used to discuss different types of participation by the citizens.

Ett undervisningsmaterial i Livskompetens : Prövat på stödgrupper för tonåringar med kronisk sjudom

Chronic illness is associated with conditions that may result in psychological ill-health in the adolescence. Consequently there is a need for development of preventive psychosocial support interventions for this target group. The objective was to develop, implement, and evaluate the effect of supportive intervention group program for teenagers suffering from chronic illness - aiming at increasing quality of life and supporting mental and physical health. Method: Six different intervention groups were conducted between 2007 and 2011, age 13?17.

Frigörelse av kvicksilver och metylkvicksilver till bäckvatten under olika perioder efter skogsavverkning :

High levels of Hg in fish in Swedish lakes have been a problem along time in Sweden. The major concern is production and accumulation of the most toxic form of mercury; methyl mercury (MeHg). Consequently, in about half of our 83 000 lakes fish contain concentrations above the recommended limit for human consumption of 0,5 mg mercury per kg fresh weight (most of it in the form of MeHg). Consumption of fish containing too high levels of MeHg may cause problems for both humans and animals. Three major sources of MeHg in surface waters are: 1) runoff from terrestrial areas, 2) deposition from the atmosphere, and 3) internal production of MeHg in lakes and streams. The aim of this study was to investigate the effect of clear-cutting on the concentration of Hg and MeHg into draining streams.

Lepenski Vir - mellan floden och skogen. En uppsats om en mesolitisk bosättning i förändring.

This essay deals with the ideas of social change in the Iron Gates Gorge site of Lepenski Vir during the Mesolithic. The change from a mainly fish-based subsistence strategy to a strategy that came to rely more on hunting and later domesticated animals could have been the onset of the social change that is noticeable in the material culture from the site. Theessay is divided in two main segments. The first consists of a case-study based on three themes that describes and searches for changes in the subsistence-, settlement- and burialpractises during the Mesolithic and beginning of the Neolithic phases, and the second part analyses the results from the case-study. It is primarily the idea of transformations and reproductions of traditions that will be dealt with in the analysis which is facilitated by a theoretic structure based on and inspired by the works of Emilé Durkheim and Anthony Giddens..

Kuna Yala ? Effekter av lokal involvering inom destinationsutvecklingen : B-uppsats

This essay has examined how the local community is involved with the tourism development on the San Blas islands and how it effects the destinations development. The method of choice has been a qualitative interview with an operator that offers trips to the destination. Also there has been made a literature study where previous research about the San Blas and the subjects of choice is being presented. During the writing process of this essay it has become obvious to us that the local community (Kuna Yala) is very much involved in everything that concerns the destination. We can thereby establish that the local community of San Blas can be placed on the top step of Arnsteins (1969) ?Ladder of Participation?.

Havsöringens (Salmo trutta) lekvandring i Själsöån, Gotland.

In this study, the sea trout (Salmo trutta) spawning migration was studied in the river Själsöån, Gotland, to assess the main external factors determining upstream migration and seasonal changes in fish parameters. Additionally population trends were studied by examination of old data. The most important external factors for upstream migration were the air pressure, air temperature and wind direction. No significant difference was found between when males and females migrated upstream. Larger females in better condition started migration earlier than the smaller females in poorer condition.

Linné hemvård : En grafisk profil till ett nystartat företag

The purpose of this work is to develop and test a design process where quick decisions and model building has a prominent role. The goal is to develop a number of products and build prototypes to be shown during the Carl Malmsten Furniture Studies spring exhibition 2012. I?m also writing a report describing my work.To reach my goal I have each day during the first phase conducted a short research and found a concept based on that days name day. Then I have continued in the workshop and worked with three-dimensional models.

HUR KAN VI REDUCERA DEN INTERNA ÖVERGÖDNINGEN SAMT REGLERA ALGBLOMNINGAR FRÅN ATT NÅ EGENTLIGAÖSTERSJÖNS KUSTZON ?? : En vision om att återfå en balans i Östersjön genom att skörda algöverskott och använda biomassan som en framtida råvara.

The Baltic Sea is one of the world?s most polluted seas. Increased discharge of nutrients due to greater populations of people, together with a slow water exchange, creates great stress on the sea. Too much nutrients leads to increased growth of algae and causes problem in the ecosystem. Even if we reduce nutrient discharge the problem still exist in the ocean. When algae dies and sinks, more nutritional substances is produced called "internal eutrophication". This phenomenon will grow in the future due to a warmer climate and the problem is spreading towards the coastal zone, which is an important site for fish recreation. By removing the abundance of algae, the nutritional and toxic substances are reduced and the algae biomass can be a future resource for biofuel production..

Konstruktion av maskin för Tillverkning av sågblad

The saw blade producer, Håkansson Sågblad AB, patented in the U.S. a new blade profiledesigned specially to cut fish and meat. The most important advantage of that blade is that its teethare not set, therefore the material lost when cutting is really smaller. The special geometry of thatprofile made that nobody had found a proper way to produce it before.The goal of the outlined work is to develop a machine to produce these new blades in afeasible way.The research approach of the project can roughly be divided into three phases:1.- Invention and development of a proper distribution of blades to produce a big amount ofthem at the same time.2.- Research of the best production process to produce the blades.3.- Main design of the machine to produce the blades.In the Thesis these three points are carefully developed and studied in the form of the startpoint of a really bigger project. Some tests had been done in order to prove all the analytical ideasand the results obtained had been satisfactory enough to give Håkansson the start point of a bigbusiness.

Det kompetenta barnet? : En kvalitativ studie om socialsekreterares syn på barns möjlighet till delaktighet vid familjehemsplaceringar

Bakgrund: Media är idag en av övervakarna inom bolagsstyrningen och forskning visar på att det är den viktigaste övervakaren för att förmedla information till allmänheten. Det finns dock tvetydig och motsägelsefull forskning kring effektiviteten i medias övervakning, då det kan finnas incitament till att inte rapportera på ett opartiskt och oberoende vis. Denna studie kommer granska medias rapportering, för att öka förståelsen för dess rapportering och huruvida det är en fungerande övervakare eller inte.Syfte: Att öka förståelsen kring om media fungerar som en övervakare inom bolagsstyrning och i sådant fall hur.Metod: Studien har en deduktiv forskningsansats där vi genomfört en komparativ flerfallstudie bestående av medias rapportering från fem svenska företagsskandaler, där rapporteringen hämtats från fyra av de största tidskrifterna i Sverige. Det empiriska underlaget har analyserats med hjälp av en analysmodell som beskriver stigmatiseringsprocessen och denna har underlättat behandlingen av det insamlade empiriska underlaget.Resultat: Studien visar på tendenser att media fungerar som en övervakare i en svensk bolagsstyrningskontext, då dess rapportering överensstämmer med de kriterier som en övervakare bör följa..

Utvärdering av utrustning för skörd av äpplen avsedda för färskkonsumtion

During the autumn 2009, a 15 hp degree project was accomplished. The objective of the study was to describe different equipment alternatives, suitable for fresh market apple harvest. A field study was conducted during the harvest period to evaluate the efficiency (kg / person/ hour), using the different equipment. Four different systems are described in the study; Pick-ing-bag, Picking-train, Pluk-O-Trak and the Conveyor Harvester. The information about the systems is based on interviews with growers together with previous studies.
