Fånggrödor i Norra Östersjöns vattendistrikt

70 % of the lakes and waters in the water district of northern Baltic Sea do not reach the requirements for good ecological status. This is mostly due to eutrophication caused by a too high deliverance of nutrients from agricultural land or effluents. Losses of particulate phosphorus through water erosion contribute to a great extent to this eutrophication. In the action plan for the water district cover crops are mentioned as a measure for reducing losses of phosphorus from arable land. This paper reviews the possible effect of cover crops in the water district and discusses what crop that would be most suitable.

Styr genus valet av Cover Story? : En fortsatt studie på projektet Cover Story, där genusaspekten kommer upp till ytan på ett intressant sätt.

Cover Story is a project, which students at Lillholms - and Ekholms School worked in during spring and fall of 2009. Several school subjects were integrated in project; social studies, art and Swedish, to empower the students to create, implement and design a magazine. The purpose of the project was to give the students the opportunity to fantasize about the future and their dreams by creating their very own Cover Story. During the project I realized that the student?s selection of magazine genre had a direct relation to the gender of the students themselves.

Trädslagsinverkan på markvegetationens utveckling i odlingsförsök med tall och contorta :

In the 1970?s it was predicted that in the beginning of the 21st century there would be a timber shortage in Sweden and a large scale introduction of the exotic tree species lodgepole pine started. An introduction of a foreign tree species means a risk of a negative influence on the forests ecosystem. Today, the stands that were established in the 70?s are middle-aged and the effect on the forest floor vegetation can be studied.

ELLE & CAFÉ : ? en studie av modemagasins omslag

ABSTRACTTitle: Elle & Café ? a study of fashion magazines cover pages.Number of pages: 38Author: Greta SimonssonTutor: Amelie HössjerCourse: Media and Communication Studies DPeriod: Spring Semester 2008University: Division of Media and Communication, Department of Information Science, Uppsala UniversityAim: The purpose of this essay is to:? Analyze the cover images from the 2007 editions of the magazines Elles and Café, using semiotic analysis.? Analyzes eventual resemblances or differences between the two magazine's cover images based upon the result of the semiotic analysis.Material and methods: The study of Elles's and Café's cover pages has been done using a model built upon semiotic analysis, developed with the purpose of suiting observation and examination of cover pages of fashion magazines. The cover pages were analyzed from the categories character, context, and environment.Main results: The main results include the observation that both Elles and Café chooses well-known figures from women's fashion industry as prime characters on their covers. In Elles, all main characters are famous women emerging from the music, television and fashion industries. The women in Café are known for similar professions.

Branschtidskrifter som contrarian indikator. : En myt eller en strategi som skapar överavkastning?

Bakgrund: Inom investering förekommer ett flertal tumregler och myter. En myt som cirkulerat bland investerare är att framsidor i branschtidskrifter, benämnt Cover Stories, skulle utgöra en indikator för en contrarian strategi. Våren 2007 presenterade den första studie där det undersöktes om Cover Stories hade utgjort indikatorer för enskilda företag i USA. Vi kommer att undersöka om Cover Stories i Affärsvärlden och Veckans Affärer utgjort en indikator på den svenska marknaden under tidsperioden 1987 till 2006. Utfallen av våra resultat kan eventuellt bidra till att investerare inte fattar beslut utifrån en felaktig myt om samband inte kan påvisas.

Bibliotekarieutbildningen vid BHS 1977 t.o.m 1999 En diskursteoretisk studie

The aim of this master thesis is to investigate changes within four discourses identified in the curriculum material of the Swedish library education in Borås Bibliotekarielinjen dating from 1977 and 1985 and its successor Library and Information Science Biblioteks- och informationsvetenskap dating from 1995, 1999. My method used is a text analytic method primarily derived from the discourse theory of Ernesto Laclau and Chantal Mouffe, yet with addition of tools from the critical discourse analysis of Fairclough. By identifying three floating signifiers within the material, i.e information, library, and librarian, and thereafter identifying their fixation, a pattern of resemblance and diversity in the fixating signs appeared between different courses of the curriculum dating from 1999. Hence I could establish an order of discourse consisting of four library discourses, a knowledge organisation discourse, a user discourse, a society discourse and a management discourse. Using this discursive order as a pattern, I could trace these four discourses back in time within the material dating from 1995, 1985 and 1977.

Vision Sjöhem : Framtagning av förslagshandlingar för flytande bostäder

Stockholm lider idag av omfattande bostadsbrist och ständigt ökande befolkningsmängd. För att möta detta ökande behov av bostäder i Stockholm finns en nödvändighet i att utforska nya vägar till att åstadkomma detta. Här finns en unik möjlighet till en förtätning av staden genom att utnyttja Stockholms stora vattenarealer för att bygga flytande bostäder.Som alternativ till den traditionella byggkonsten ämnar examensarbetet till att demonstrera de kvaliteter som finns med att bo på vatten genom att utforma ett attraktivt bostadsområde med flytande konstruktion. Projektet illustreras i det tidigare hamnområdet vid Liljeholmskajen i Årstadals hamn, Stockholm. För att åstadkomma detta utförs fallstudier på olika typer av flytande konstruktioner som finns på den svenska marknaden för att fastställa de bästa konstruktionslösningarna som leder till färdiga förslagshandlingar.Resultatet visar att ett flytande bostadsområde är genomförbart med dagens teknik som ett sätt att förtäta staden.

? Effekter av en liten biogasanläggning hos småbrukande bönder i Östra Afrika : En studie med utgångspunkt från en småbrukande familj i Kadongo, Kenya

Syftet med den här uppsatsen är att redovisa för de effekter som kan sespå odlingssystem samt livssituation hos småbrukande bönder i Östra Afrika efter ett införande av en liten biogasanläggning kallad "floating drum". Anläggningen genererar rötrester som används som gödslingsmedel i odlingssystem och biogas som bränsle i matlagningssituationer. Resultatet baseras på uppgifter från litteratur, fältstudier och en enkätundersökning. Uppsatsen har sin utgångspunkt från en fältstudie hos en småbrukande familj på landsbygden. Studien genomfördes i ett område som heter Kadongo och ligger i nordvästra Kenya.

Risk för bostadsägare - en analys av risken vid förändringar av ränta och elpris

Since 1996 the Swedish households have ten folded their volume of loans for own homes that is attached to a floating interest rate. Also in 1996 the Swedish electric market was deregulated. These two facts have increased the volatility in the household expenses for these two commodities. This thesis studies the risk for homeowners attached to the exposure against the electric and the credit market. The risk model used is Cost-at-Risk which is usually used by public authorities for analysing the risk involved with national debt.

Short-term responses of the field layer vegetation in a south Swedish deciduous forest after establishment of wild boars (Sus scrofa)

Inside the south Swedish national park Dalby Söderskog, wild boars (Sus scrofa L.) have been visiting since 2010. The presence of wild boars has earlier been proven to impact both soil and vegetation characteristics, both positively and negatively. Still, there is a lack of knowledge regarding the rooting effect on the vegetation in deciduous forest within the native range. In this study, I have compared the field vegetation collected before and after the invasion of wild boars in 74 permanent experimental plots. More specifically, the study aimed to qualify the effect of wild boar rooting on cover ratio, species richness and species composition in a temperate deciduous forest.

Riktiga män äter kött och kvinnor äter inte alls : En kvalitativ bildanalys av omslagen på sex olika livsstilsmagasin för män respektive kvinnor.

This study was a qualitative analysis of the covers of six lifestyle magazines, three addressed to women and three addressed to men. We have studied the cover photographs, the teasers and their relations. The purpose of this study was to answer the questions: According to the magazines, what are male interests and what are typical female interests? Who is the ideal man and who is the ideal woman? Is there a certain way you need to look to be able to be on a magazine cover? And how often do the magazines encourage you to consume? The study was based on thirty covers, five from each magazine. The Swedish magazines are VeckoRevyn, Amelia, Damernas Värld, King of Sweden, Café and the American version of GQ. We?ve used semiotics and rhetorical methods to analyze the material.

Effekter av urbanisering på grönalgen trädgröna i Linköpings stad med omnejd. : Biologiundervisning i närmiljön

Urbanization has for a long time been a threat to our biodiversity. Epiphytic organisms such as lichens have been negative affected by traffic pollution and the new urban environment surrounding their old habitat (van Her 2001). Another epiphytic organism is the green algae Desmococcus olivaceus. Unlike lichens the green algae is favoured by polluted areas. The aim of this study was to investigate if time in urban environments affected the cover of the green algae on old oaks.

Biologiska behandlingsmetoder för rening av rejektvatten från biogasproduktion

In this literature review the characteristics of two free-floating macrophytes, water hyacinth   (Eichhornia crassipes) and duckweed (Lemna sp.), and two microalgae, Chlorella and Scenedesmus, have been examined regarding their suitability as efficient nutrient removers in the treatment of wastewater with high levels of nutrients and suspended solids from a biogas plant in Loudden. The needs required for the plants to be able to grow in wastewater and the amounts of biomass they can produce have also been studied. The results show that Chlorella is capable of a very high uptake of nutrients in photobioreactors with high nutrient loadings. With an ammonia uptake maximum value at 10900mg/m2/d Chlorella outshines the other organisms in this study. The test organism that performed the closest to Chlorella in terms of nitrogen uptake was water hyacinth with an uptake about 1602mg/m2/d.

Spawning site selection of brown trout in habitat restored streams

During the timber floating era, most of Sweden?s watercourses were altered. This decreased the amount of available spawning habitats for salmonids, and hence had a negative effect on the riverine brown trout (Salmo trutta) populations. Reconstruction of spawning grounds is today a common measure in restoration of altered streams in Sweden. However, very little evaluation of the effectiveness of these reconstructed spawning grounds exists.

The effects of Gotland pony grazing on forest composition and structure in Lojsta hed, south eastern Sweden

Livestock animals affect their environment in a number of different ways, mostly through grazing and trampling. This study focused on the effects of Gotland pony grazing on forest structure and diversity, and the impact on ground cover. To compare the fenced and grazed area with a reference area outside the enclosure a number of transects were used. The study showed that there was no significant difference in height structure and diversity between the compared sites; however, there were a significantly higher proportion of damaged trees inside the enclosure. The ground cover variables showed a higher amount of bare soil, plant litter and wood-rush (Luzula sp.) inside the enclosure whilst grass was more frequent in the reference area.
