Willingness to pay for improved maize seeds among smallholder farmers : a study of the input factor market in Kenya
Kenya is considered to be a developing country. This means that basic needs such as nutrition are not met for an extended period of time (www, Sida 1, 2012). Approximately half of the population is living under the poverty line (www, CIA 1, 2012). Agriculture is the largest sector in the country, employing 75% of the population. These are thereby directly dependent on the sufficiency of outputs received.
Dagligvaruhandelns strukturomvandling i Gävleregionen (A-region 56)
Syfte: Uppsatsens syfte är att beskriva dagligvaruhandelns lokalisering och strukturomvandling i Gävleregionen (A-region 56). Att studera dagligvaruhandeln ger en bild av samhällsförändringen över tiden och en föraning av framtida tendenser.Metod: Undersökningen genomfördes med hjälp av data tillhandahållet av Handelns utredningsinstitut (HUI). Dagligvarubutikernas lokalisering visas i geografiska kartor och de olika butikstypernas marknadsandelar studeras för att belysa strukturomvandlingen.Resultat & slutsats: Det presenterade resultatet visar ett allt glesare butiksnät med färre och större enheter.Förslag till fortsatt forskning: Uppsatsen begränsas till att endast undersöka dagligvaruhandelns lokalisering och strukturomvandlingen i Gävleregionen (A-region 56). En liknande studie över ett större geografiskt område skulle ge en än bättre bild över dagligvaruhandelns utveckling.Uppsatsens bidrag: Uppsatsen kan med fördel studeras av intressenter inom samhällsplanering, fastighetsekonomi och handel..
Kloning av möjlig promotorsekvens uppströms kloritdismutas i Ideonella dechloratans.
Perchlorate and chlorate are naturally occurring in the atmosphere, from here it sediments into groundwater and soil. The pollution is increased by discharges of perchlorate and chlorate from agriculture and paper mills. Bacteria capable of reducing perchlorate and chlorate to chloride and oxygen can be used to get rid of these contaminants. However an anaerobic environment needs to be sustained in order for this reaction to be used. For this reduction to work in an aerobic environment as well, a greater knowledge of the reducing enzymes, regulating factors and their corresponding genes is needed.
Evigt offer eller alltid gärningsman? : Framställning av invandraren i den nätbaserade dagspressen
The purpose of this study is to examine how immigrants are portrayed in the Swedish daily newspapers online reporting. The essay investigates in what context immigrants, as individuals, are made visible and how they and their origins are reproduced. The study focuses on the roles victim and aggressor, and is also investigating potential differences between morning and evening newspapers.Present theories are discursive discrimination, critical discourse analysis, cultural racism, stereotypes and structural discrimination. Adopted methods are qualitative and quantitative content analysis, based on the Global Media Monitoring Project-tool.The results show that immigrants are not individually stereotyped or depicted negatively, but that their immigrant origins often have a central part of the story, that they are mentioned mainly in connection with negative news and that negatively charged words occur frequently. .
Markberedningsresultat och plantbildning med såddaggregaten Humax 2-4 och KSM-såddskopa
Fördelarna med skogssådd är bland annat att de kan ge stamtäta bestånd med potential att producera träd med bra vedegenskaper och bättre utvecklade rotsystem samt att sådder har en högre biomassaproduktion per ytenhet jämfört med planteringar. Nackdelar som kan nämnas är att de ofta täta förbanden ger ökade kostnader vid eventuella röjningar och att föryngringsresultatet är mera osäkert för sådd än för plantering.Mekaniseringen av skogssådden startade under 1970-talet. Humax och KSM är två kranspetsmonterade aggregat för skogssådd. De har utvecklats för att användas på marker med svår ytstruktur där dragna såddaggregat som harv och högläggare har svårigheter att skapa tillräckligt mycket lämplig såddbädd på grund av att aggregatet inte kommer ner mellan hindren eller att basmaskinen inte klarat av att köra över hela arealen. Fördelen med KSM och Humax är att aggregaten är kranspetsmonterade vilket gör att föraren väljer var aggregatet skall markbereda och på det viset kan markberedningen göras mellan hindren samt att kranarmens räckvidd gör att basmaskinen inte behöver köra över hela arealen som skall markberedas.
Hänsyn till mark och vatten vid slutavverkning : en fältstudie på känsliga marker
The purpose of this study is to investigate if there is enough consideration taken to sensitive forest areas close to water or wetlands during clear cutting assignments, and to estimate the extent of damage made by forestry machines used at that time. A field and literature study is used to show how to improve and prevent the damage made in the wake of the machines.
This study is made for Sydved, and shall culminate in a policy to prevent ground damage during their clear cutting assignments.
The areas which were part of the field studies were clearcuttings on fine grained soil close to water and wetlands. The purpose was to find out if the water had been affected, what had been done to prevent ground damages and what more could have been done.
The results of the field studies show that more work needs to be done to reach up to expectations. More information about the assignment area, better planning of sensitive regions, and strengthening of the main haul roads with brush are some of the improvements that can be done. There is also a need for more exact guidelines, follow-ups and education for everyone involved to have the same goals and understanding to prevent ground damage..
Lilaköttig taggsvamp, Sárcodon fuligíneovioláceus : miljökrav i Sverige och en analys av vad som styr artens etablering
Burnt Spine-cap Sárcodon fuligíneovioláceus are one the most endangered
mycorrhizal fungal species in Europe. They have their main distribution in Sweden. It
form mycorrhiza with pine and dependent on limestone, which makes it connected to
a rare environment. It has therefore been important to study the ecology of it further
and to recognise the requirement it has on the environment more accurate and what it
need to establish in a new area. In this study, 31 of 34 known sites in Sweden was
visited and studied in field and their history analysed through aerial photographs.
Dimensionering av monopåle för grundläggning av vindkraftverk till havs: Baserat på finita elementanalyser
Vindkraft är en förnyelsebar och utsläppsfri naturresurs. En fortsatt global utbyggnad av land- och havsbaserad vindkraft är att vänta. Fördelar med vindkraft till havs är bättre vindförhållanden och lägre krav på hänsyn till landskapsbild och närboende, vilket medför att vindkraftverken kan byggas större och därmed kan vinden utnyttjas mer effektivt. För havsbaserade vindparker krävs en lösning för grundläggning som är rationell och anpassningsbar. Vid dimensionering av konstruktioner till havs är det viktigt att ta hänsyn till den cykliska belastningen från vind och vågor konstruktionen utsätts för.
Affären Astoria Cinemas: Om en biografkedjas korta levnad
In May 2005 the Swedish cinema chain Astoria Cinemas is founded and in July two years later the company goes bankrupt. In this thesis Astoria Cinemas is used as an example to illustrate the conditions for a culture-producing company in a commercial market. The purpose of the thesis is to discuss the strategies for cultural production that has been used by the actors involved in the Swedish cinema market, and also to discuss the structural environment on that market. It is a qualitative study based on interviews and documentation. A few conclusions are possible to draw from the empirical material, one is that Astoria Cinemas? management did not agree on the company?s business strategy and therefore might have acted strategically inconsistent.
SSP : En kvalitativ studie av ett samarbete mellan socialtjänst, skola och polis
This thesis has examined a co-operation called SSP, between the social authorities, the school and the police, located in Malmö. The intention with SSP is to prevent crime and drug use among juveniles but also to evolve a structure for a long-term co-operation between the authorities.The purpose of the thesis was to understand and analyse what the co- operation represented and stood for. The study also examined how the co- operation was effected by differences in the organisation of the three parts.The main questions were the following; what does SSP contain, is SSP preventive and for whom, what motivates the co-operation and how is the cooperation effected by the view the authorities have on the target group?The method used for answering the questions was based on qualitative interviews with the three authorities involved. We have also searched for literature on the subjects involved.The main content of the thesis has showed that the limits of SSP are diffuse, and the focus of the co- operation lies at a structural level.
Växters upptag av spårämnen från rödfyr : ett odlingsförsök vid tre rödfyrshögar i Västra Götalands län
Burnt alun shale and lime is the residual product that was formed when alun shale was
used as fuel to convert limestone to quick lime. The material contains arsenic, vanadium,
molybdenum, cadmium, nickel, lead, and uranium among other elements. The aim of this
paper is to examine the uptake of trace elements in vegetables grown on burnt alun shale
and lime to determine whether or not the surrounding environment and humans are
exposed to these elements by eating plant products.
A cultivation trial was carried out where onion, carrot, and lettuce were grown on three
mounds of burnt alun shale and lime in the Falköping area in Sweden. The treatments
were burnt alun shale and lime mixed with peat, only burnt alun shale and lime, and a
reference soil. The reference plots were natural soil mixed with peat adjacent to the
mounds.
Kvarteret Mjölnaren : bostadsgård på bjälklag
Uppsalahem, Uppsalas municipal renting company, builds about 250 new apartments every year. Mjölnaren in Kungsängen is a project which contributes with about 130 new renting apartments finished in 2010/2011.
This report has lead up to a proposal. Focus lies on how to create a courtyard on beam joists where shape, style and different types of functions are important elements. The report also brings up ground materials, details, plants, availability and built up plantings. All these aspects together are what create a well functioning and pleasant courtyard.
All through the work with this report I have taken part of the meetings concerning the project.
Ekonomisk kompensation vid föräldraledighet, vadå? Utifrån arbetsgivarens perspektiv
The purpose with this essay was to analyse the view of parental leave in the public and private labour market. How does the economical compensation affect the parent's use of parental leave, with focus on the fathers "earmarked" months? Were there any differences in private companies and public organisations? We chose to look at past research and theories about father/men's usage of "60 day parental leave" from a point of gender and equality perspective. In regard to our questions we preformed qualitative, semi structural interviews. We picked people at random to interview at both private companies and public organisations that had or had not extra economical compensations except what the social insurance office paid during parental leave.
Skattning av den integrerade hydrauliska konduktivitetens variation kring Tunåsens infiltrationsanläggning : En utredning av påverkan från möjliga osäkerheter i befintlig information
Estimation of the variation in the integrated hydraulic conductivity around the Tunåsen infiltration facility - An investigation of the effects of uncertainties in existing informationAlmost half of Sweden?s drinking water volume is produced from groundwater. The main fraction of this is extracted from eskers, some of which allow for very large extraction rates. Despite this, the groundwater volume is not sufficient in some areas. This has led to an extensive use of artificial recharge.In Uppsala, the total volume added through artificial recharge is divided between four infiltration facilities.
Föryngring och produktion av skog på torvmark
Kunskapen kring svensk torvmarksbeskogning är undermålig. En kunskapslucka som till stor del beror på att torvmark tidigare bedömts som ointressant mark i samband med skogsproduktion. Detta beror mycket på det svenska regelverkets restriktioner mot markavvattning och gödsling samt miljöaspekterna som berörs och den aktivare skötsel som krävs. Det ökade behovet av skogsråvara gör att skogsbruket söker nya marker där torvmarken har potential att etableras för skogsproduktion.Studien är en kunskapssammanställning som lyfter fram kunskap kring skogsbruk på svensk torvmark med fokus på föryngringsprocessen. Finland använder torvmarker i skogsbruket på ett sofistikerat sätt.
