Fodder to ruminants within agroforestry systems in Rwanda - species and management
Rwanda is one of the poorest countries in the world and about 70-80 % of the population lives in rural areas. The land is strongly affected by land erosion which makes it difficult for the agriculture and food production. Agroforestry is a system where tree plantation is combined with livestock- and crop production. The system provides soil fertilization and binds the soil together. Some of the trees used in agroforestry systems are also used as fodder.
Betydelsen av anlagda våtmarkers area och ålder för förekomst av sjöfågel inom Linköpings kommun
The aim of this study was to examine what impact restored and constructed pounds and wetlands have on waterfowls in the area of Linköping. The birdlife in five constructed wetlands werechosen to investigate if specific factors like age, size and vegetation affected the avian diversity in wetlands. Also, extra focus has been given to the threatened Horned Grebe (Podiceps Auritus), breeding in the studied area. The results showed that the number of species as well as individuals of waterfowl and Horned Grebe changed over time in what might be a result of succession in the wetlands. Comparing the number of birds to the size of the wetlands showed a clear correlation. Larger areas inhabited greater numbers of species and individuals.
In search for sustainable alternatives to lawns : connecting research and landscape design
A large part of Sweden?s green, urban landscape is covered by lawns. Approximately 80 000 ha of maintained grass lawns are part of public courtyards, schoolyards, parks, golf courses, sport fields and traffic environments. Beyond this figure, the lawn is also an essential element in most private villa-gardens. Lawns have become a universal phenomenon through the dispersion of landscape aesthetics from the Western world.
Från svartvit till färg : en studie av färg i Michelangelo Antonionis film Den röda öknen
Michelangelo Antonioni (1912-2007) belonged to a generation of filmmakers that breathed new life into cinematic expression in the annals of modern-day European film history. By employing his background as a documentary filmmaker, Antonioni used these skills to help establish his own particular style. There was a distinct evolution of style which progressed during his triology L´Avventura, La Notte and L´Eclisse, 1959-1962. This theises presents a comperative study between his earlier films in black and white and his first color film - Il deserto roso, from 1964. By observing color in relation to narrative, dialouge, acting and elements of mise-en-scène, I suggest different answers than those previously discussed among critics concerning this interrelationship.
Ut ur Östersjön genom vassen : beskrivning av övergödningsproblematiken samt optimering av en reningsmetod genom skörd av vattenväxter
This study is based on AgroSeas business idea from environmental problems to valuable resource, with the objective to optimize a method to purify the already eutrophicated Baltic Sea by harvesting water plants, mainly reed. The nutrients will then be recirculated to arable land through residues from biogas production. The amount of nutrients that can be removed by harvesting the biomass
depends on the amounts of biomass and the nutrient content of it, which in turn is strongly dependent on the nutrient concentration of the surrounding water. Vegetation suggested in the study for an effective nutrient uptake is helophytes: reed, cattails, reed canary grass, reed sweet
grass in shallower water and lemnoideaes: duckweed and nymphaeids in the deeper parts.
Competitive species has high purification ability but requires regular maintenance to avoid channeling and overgrowth. Regarding time and method of harvest, effectiveness may be improved by: harvesting plants above the water level and after flowering, a border is kept, harvesting twice a season, a bigger machine and a regular maintenance.
This literature has illuminated a major environmental problem and it has been suggested
optimizations for a method for cleaning the Baltic Sea through harvesting water plants, but to get a
definite answer for the optimal method for each site tests should be carried out, this because many
factors determine to what is suitable for each, specific environment.

Renkavlens biologi - möjligheter till kontroll
Renkavle har under lång tid varit ett stort problem för lantbrukare i stora delar av norra Europa och har etablerat sig på större arealer även i Sverige. Genom sin bio-logi är renkavle mycket väl anpassad till odling av höstsådd spannmål, speciellt i kombination med reducerad jordbearbetning. Det finns en ökande trend av både höstsådd spannmål och reducerad jordbearbetning som talar för att problemen med renkavle kommer att öka framöver. Även den pågående klimatförändringen mot ett varmare klimat i Sverige förbättrar förutsättningarna för att renkavle ska etablera sig längre norrut. Renkavle är ett ogräs som kräver en mycket hög grad av kontroll för att inte öka kommande år eftersom fröproduktionen hos renkavle kan vara mycket stor.
Att starta eget - en väg till frigörelse? En kvalitativ studie om mikroföretagare i Sydafrika
The aim of our study is to explore the empowerment process among micro-business owners in Kayamandi, a black township of Stellenbosch in South Africa. What are the positive and negative implications for the empowerment process? Another aim is to find out the role of local and international support in this process. The theoretical framework of this study revolves around the concepts of gender, power and empowerment. Our methods are qualitative interviews and observations.
Utfodring av föl före och efter avvänjning :
Swedish horse breeders have generally very few mares producing a few foals a year and the
breeders have relatively few traditions, little knowledge and experience to breed foals
successfully. It is therefore important to provide adequate information about new findings in horse nutrition. However, there is not much research about feeding the suckling foal to ensure a sound growth. Current feeding recommendations in the literature seems to be different. This gives a confusing message and the information is difficult to apply.
This paper reviews some publications in the area of feeding the suckling and weaning foal.
Most authors stress that it?s important to start feeding the foal early in life.
Digital 3d landskapsmodellering : detaljeringsgradens betydelse för läsbarheten hos digitala tredimensionella landskapsmodeller
In this paper I have sought a suitable level of abstraction in my models describing the landscape; the models are made to be viewed from eyelevel. Because of the spectator being ?in the model? the objects included need a certain degree of realism. I have sought what is needed in the model to be able to comprehend that the model is showing a landscape. Some details might be unnecessary.
En ekonomisk hållbar växtodling i sörmländsk mellanbygd :
We have been looking at three different types of agriculture in Södermanland, in the middle
east of Sweden. We call the different types for Intensive, Extensive and Mix. The purpose is
to get an economic defensible plan for how to run different farm sizes. We also have been
looking at the working hours and how many hours the different types will give.
We have a farm called Taxinge Gods as our pilot farm. Taxinge Gods grow 407 ha land and is
located 60 km southwest from Stockholm.
Vattendraget på Kåbo golfbana : en kartläggning som ett steg i golfklubbens miljöarbete
This degree project studied surface waters on Kåbo Golf Course in Uppsala, Sweden, with the aim of determining the status of the water and how it is affected by the activities of the golf club, and to obtain suggestions of measures to create better conditions for the water environment on and around the golf course. The project forms part of the environmental protection work of Kåbo Golf Club, which is working towards achieving environmental certification from the Swedish Golf Association (SGF).
The study is based on literature studies and quantitative and qualitative field studies of water on the golf course, with the focus on environmental factors identified as being important for the golf industry and on strategic environmental goals developed by SGF.
The number of open water bodies in the Swedish landscape has substantially declined during
the past 200 years, so it is important to save those that remain. This study showed that the surface water at Kåbo Golf Course is an important element in the surroundings since the area contains few wetlands, which can be a habitat for large numbers of species. The stream and ponds on Kåbo Golf Course also have the important function of serving as water hazards in the game and adding difficulty and variety to the course. Since Kåbo Golf Club wants its surface waters to look aesthetically appealing, extensive algal growth and drying up of ponds during parts of the year are regarded as problems.
Svart organisation kontra vit institution : The Black Panther Party i populärkultur, det amerikanska historiebruket och film som socialt minne
Syfte med denna uppsats är att undersöka hur lärare arbetar med att introducera skönlitteratur vid klassgemensam läsning. Uppsatsen tar också upp vilka eventuella konsekvenser lärarnas val av introduktion kan få för elevernas läsutveckling. Undersökningen baseras delvis på teorier kring hur elevers möjlighet att påverka valet av skönlitteratur kan påverka deras inställning till vad de läser, men i första hand grundar sig uppsatsen på forskning kring kontexten vari skönlitteraturen placeras och hur den påverkar elevernas läsning. För att uppnå syftet med uppsatsen genomfördes kvalitativa intervjuer med fem lärare verksamma i grundskolans år 7?9.
CAPM - en vingklippt modell? : En kvantitativ studie om betavärdets påverkan på Sverigefonders avkastning
Idag äger många svenskar andelar i olika fonder. Detta beror delvis på att det allmänna pensionssystemet i Sverige idag består av en premiepensionsdel, där individen kan göra ett individuellt val hur dennes pensionspengar ska investeras. Gemensamt för investerare är att de vill erhålla en god avkastning. Ett vanligt sätt att bedöma förväntad avkastning i en finansiell tillgång kallas Capital Asset Pricing Model, eller CAPM. Detta är en mycket behandlad, debatterad och även kritiserad modell.Förutom CAPM utgår studien från en nyare teori som heter Black Swan theory.
Utfodring av sällskapskanin. Vilka råd ger vi djurägarna?
The most suitable method to answer the issues of this study was to do a combined literature- and questionnaire study. The literature part of the study was based on Original Research articles, Review Articles and books with a list of reference literature after each chapter and the purpose was to answer the questions ?What feed items should be given to rabbits in different life stages? and ?Which problems may develop from an inadequate diet??
Two questionnaires were constructed. One was sent by e-mail to small animal veterinary hospitals to be answered anonymously by veterinary nurses. The other was linked to from two internet forums, that with rabbits as their focus.
Från Black Maria till Black BOX: en filmfestivalupplevelse sammanvävd med livemusik
I dagsläget existerar det mer än 500 filmfestivaler runtom i världen, flera av dessa festivaler erbjuder sina besökare ett annorlunda koncept och inriktning av filmgenre(Turan, 2002). Enligt den research som jag har gjort finns det dock ingen filmfestival som bygger sitt koncept kring blandningen av livemusik och film. Syftet med denna studie har varit att planera och genomföra en filmfestival som skapar förutsättningar för en annorlunda filmupplevelse där film och livemusik blandas samman. Jag har studerat befintlig litteratur kring film och filmfestivaler för att sedan kunna använda mig av den kunskapen i planering och genomförandet av produktionen. Jag har också genomfört en intervju med Johan Karlsson som är festivalchef för Flimmer Filmfestival, där de har experimenterat med film och livemusik.
