Bäddodling av matpotatis :

This study investigated potato growing in beds as an alternative to conventional ridges.It was based on results from field trials on bed-grown potatoes carried out by Halland Rural Economy and Agricultural Society in 2007, studies of literature and interviews with farmers with experience of bed growing of potatoes. Due to their shallow root system, potatoes are one of the most drought-sensitive crops. Potatoes are often grown on sandy soils with poor water-holding capacity. Factors such as total yield, tuber size distribution and quality defects are negatively affected when water becomes insufficient. Wide beds have a more flat top which leads to more uniform water infiltration. Further on, beds have lower soil surface area due to its shape, and therefore, retain water more efficient. In the field trials, which were carried out at the Stjärnarp Estate near Halmstad, potatoes were grown in beds alongside a conventional ridge-grown crop.

Skogs påverkan på vindkraftsproduktion - en fallstudie av vindkraftverk vid Andersfält.

The purpose of this master thesis is to investigate how nearby forests affect the energy production in wind turbines. To reach the purpose a case study is performed on three wind turbines sited on a field in a north-south line at Andersfält in the municipality of Halmstad, Sweden. Approximately 100 meters south of the southern wind turbine a forest is situated. The case study is divided into three sub studies where the difference in energy production, the affect of the forest and a wind meteorology model, WAsP, is studied. The result show that the forest have a significant influence and that the WAsP-model gives an incorrect result of the energy production in wind turbines sited near a forest..

Prevention och orsaksinriktad behandling av gingivit, parodontit och karies med hjälp av motiverande samtal

Background: Traditional oral health education is seldom enough in order for dental care personnel to motivate their patients to good, long-lasting oral health care habits and there is a need for evaluation of other more efficient methods. One of these methods is motivational interviewing. An overview of its origin, definition, theoretical background and practical methods is given by way of introduction. Aim: The aim of the investigation was to review studies that had used motivational interviewing in order to obtain oral health, focusing on prevention and treatment of gingivitis, periodontitis and dental caries. Method: Systematic review. A search question was run through the databases ASSIA, ERIC, PsycINFO, Social Services Abstracts, Sociological Abstracts and PubMed. The articles were reviewed based on defined inclusion and exclusion criteria. Results: Five publications (based on three studies) met the inclusion criteria.

ICT-behov och -verktyg inom byggproduktion : En undersökning av användbarheten, användarvänligheten och implementeringsförutsättningar av ett ICT-program

Byggproduktionen är, på grund av sina invecklade arbetsmoment och dynamiska arbetsplatser, drabbad av svåra informations- och kommunikationsproblem. Veidekke Sverige AB använder sig av virtuellt byggandet (VDC) för att lösa dessa hinder i utförandet av sina projekt. VDC tillämpar flera olika informations- och kommunikationstekniker (ICT) och har visat sig vara lönsamt vid projektering. Under projektering med VDC samlas alla beslutsbehöriga parter i ett interaktivt rum där information förmedlas snabbt och effektiv med hjälp av olika visualiseringstekniker. Då VDC saknar liknande arbetsmetoder som kan tillämpas i produktionen, används fortfarande traditionella informations- och kommunikationsprinciper.Genom ett samarbete med Veidekke implementerades ett ICT-program i ett bostadsprojekt för att undersöka hur dess funktioner påverkade de rådande informations- och kommunikations-problem.

Klövviltets nyttjande av foderraps på viltåker och betespåverkan på angränsande skog

Today we have more game species than ever before in our landscape, both regarding number of species and number of individuals. The increasing number of wild species is an increase in game recourse for the countryside. The increase of game species, however, has negative effects on forests and agriculture land. The negative effects for forestry are damages on economic important trees, due to losses in production and quality. However there are ways to decrease the damage on valuable and important trees.

Impact of Eucalyptus plantations on pasture land on soil properties and carbon sequestration in Brazil

Soil organic carbon (SOC) stocks and fluxes in forest ecosystems are influenced by natural and human disturbances. In the tropical regions the highest impacts on disturbance in forest C cycles are related to human activities such as conversion of natural lands to cropland and pasture areas and to forest plantations. The disturbances in the forest C cycles will release CO2 emissions to the atmosphere triggering global warming. In this study the focus was set in subtropical soils in Brazil, south extreme region of Bahia. The aim of the study was to investigate whether reforestation of Eucalyptus plantations under former pasture areas will help mitigate climate change through carbon sequestration.

PR och trovärdigheten : en studie av PR-byrån Four C och dess kund Akzo Nobel

PR appears to be an indistinct division and a complicated resource for companies to value. The current circumstances are negative to the credibility and reliability of PR. This study emphasizes how an application of return on investment contributes to a more strategic use of PR and increases the status and credibility for the division.We experience that measuring the economic value of PR is of great importance and of current interest with few prior studies made. The purpose of this study is to find out how a PR-agency and one of its clients relates to and works with evaluation of PR-activities and to which extent the economic contribution of the activity is measured.The foundation which the theoretical reference grounds on is theories of Delusions of PR and the use of benefit-cost analyzes, Stages and Levels for Evaluating Public Relations Programs, Marketing Return on Investment and PR Return on Investment. The theoretical reference serves as a base during the analyze of the study.The conclusion, based on the empirical body of information, is that an application of return on investment could contribute with a higher status and credibility for the PR-division.

Dataspelsarvet - klassiker och kanonisering

This master thesis deals with computer game classics and a possible computer game canon. It looks closer at four computer game genres - adventure, RPG, action and strategy - in order to discern which games are considered classics and what characterizes them. To answer the first question a quantitative research method was used. 675 computer game reviews from 5 Internetsites were examined in order to see which games are mentioned most often in this context and therefore might be considered classics. To answer the second question a qualitative research method was used.

?Det var väl ändå litteratur det hela skulle handla om?? ? En idéanalys av värderingar kring Augustpriset i svensk dagspress

The aim of this Master?s thesis is to examine values expressed towards the Swedish literary award Augustpriset in a selection of articles from Swedish newspapers published between the years 2000-2007. The questions posed in the study are: What types of values concerning Augustpriset are expressed in a selection of cultural journalistic articles? How is the relationship between intellectual culture and commercial culture reflected in the articles? How are positive and negative standpoints justified? How can Augustpriset and the journalists be understood as parts of intraconversion on the literary field? The study?s qualitative textual analysis is theoretically based on Pierre Bourdieu?s theory of the literary field. The method used for analysing the articles is idea analysis using dimensions constructed from Bourdieu?s description of two polarities, the intellectual and the commercial, of the literary field.

There were also two questionnaires sent to the museums' Facebook followers. The Facebook followers have given answers about why they follow the museums but it also sheds light on age and gender of the followers.

Uppföljning av plantering på nedlagd åkermark i Skåne 1991-1996 :

The study was performed for the Swedish Regional Forestry Board in Södra Götaland. The study examines broadleaf plantations on former farmland that were planted between 1991 and 1996 with subsidy payments for conversion of farmland into forest. In particular, the study reviews forests planted in 1991-92 and 1994-96. In the early 1990s, Swedish agriculture was deregulated and direct subsides to farmers ended. The Swedish state instead granted farmers financial support and offered incentives for conversion of farmland and investments in order to make their unproductive land productive. The state supported conversion of farmland to broadleaf forest, forest for energy biomass production, or establishment of wetlands on former farmland. The County Administrative Boards and Regional Forestry Boards together monitored the planting of broadleaf forests.

?Det behöver inte vara värsta Rihanna för att det ska vara ett A? ? : Om betyg och bedömning i sång på grundskolan.

Uppsala University Library owns eight volumes of manuscripts attributed to the academy equerry Johan Leven Ekelund (c.1701?1775). In this thesis, I apply methods from the field of material culture studies in order to establish which of the volumes that formed the donation from Leven to the library mentioned in his will. By mapping certain markers such as places, names and dates I am able to identify to some extent where Leven gained his practical skills and which writers influenced him. By analysing the texts, I draw the conclusion that the manuscripts can be divided into groups aimed for different audiences.
