Kan man se med öronen? : En uppsats om filmljud
This thesis is about the interaction between composition, notation and interpretation and what occurs between the fields with an extended notation.The purpose of my thesis is to examine the possibilities tothoroughly describe and map the sounding samples through composition prototypes.The thesis has a qualitative approach, and the empirical material consists of different documents about notation and from interviews with musicians and students about the instruments used in the thesis.It also consists of 17 compositions recorded at Örebro University School of Music as an appendix.The analysis shows that the context in which the symbols are found, play an important role in performing them. It also shows that the performers are rooted in a traditional way of performing..
Effekt av karbonatisering med biogas på aska från trädbränslen
It is essential to reuse- and recycles residues to decrease the amount of deposit materials and reach sustainable energy use. Two ways to work towards this is to recycle wood ashes to the forest as nutrient compensation and extract biogas from combustion of biomass.The aim with this study was to decide whether wood ashes that been used for biogas upgrading with accelerated carbonation also can be used as a nutrient compensation in the woods according to recommendations from the Swedish Forest Agency (Skogsstyrelsen).The ashes that were used in this study came from Johan Andersson who works at JTI in Uppsala, who also treated the ashes with biogas. The ashes have, in both untreated and treated condition, been analyzed in this study according to contents of elements, leaching properties, hardening properties and contents of crystalline phases, to evaluate what impact carbonation with biogas has on the ashes.The accelerated carbonation led to hardening of the ash, and decreased amount of CaO- and increased amount of CaCO3. The CO2-uptake also entails a dilution of the elements, and the content of nutrients and trace elements decreases. However the results show an indication of an uptake of S from the biogas to the ash, since the dilution had a smaller impact on S than the rest of the elements.
Våtmarker för näringsretention i Lillån : var bör de ligga och vilken effekt kan vi förvänta
Construction of wetlands in the agricultural landscape may reduce nitrogen and phosphorus
transfer to streams, thereby reducing the eutrophication of lakes and seas. The agriculturalstream Lillån, a tributary to stream Sagån, ends up in Lake Mälaren and is transporting large amounts of these plant nutrients. The aim of this study was to estimate how hypothetical wetlands of different size and location may reduce nitrogen and phosphorus load from stream Lillån. Estimated nutrient retention in several small wetlands was compared to retention in a single large wetland based on existing data from the agricultural stream and from a nearby smaller stream. Retention in the stream was suggested to decrease along with the nutrient concentration in the water.

Näringsretention i återskapad våtmark på betesmark : studier av en mad vid Bornsjön
It is important to construct or recreate different types of wetlands and study their retention of nutrients, since knowledge of their effectiveness in this matter is poor. In 2003 a wetland was constructed on an old meadow on the western shore of Lake Bornsjön in central Sweden. The main purpose of the wetland was to reduce the amount of phosphorus entering the lake, which is the back-up water supply for Stockholm when the city cannot obtain water from Lake Mälaren. Large areas around Lake Bornsjön consist of agricultural land and the nutrient concentrations in the inflows to the lake are usually relatively high (approx. 1 mg/l total nitrogen and 0.05-0.1 mg/l total phosphorus).
Sveriges ensamkommande barn. En studie av konstruktionen flyktingbarnet.
Children who have fled to Sweden, without their parents or guardians, have been a controversial subject during the winter of 2002. Their situations on refugeestations and the responsibiliy by community and the state have been discussed. My composition is about these children. The composition is not about the situations of the children - focus is instead on the people who operate with the children; community, state and organisations. I want to find empirical levels which show what the children associate with.
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.

Orden bland drakar och demoner : En språkstudie av svenska rollspelsböcker
The purpose of this essay was to do a research about if the language in Swedish role-playing books is used correctly and if the composition along with the possible language errors makes the books hard to understand.This research was also about to find out why these problems occurs and if the authors are aware of them.I choose books from two Swedish role-playing games, Eon and Drakar och Demoner. I read them trough, noted the mistakes made and put them together in a scoring table. I also did a LIX-test on the books and interviewed one of the authors.The results shows that the books to Eon is harder to read than the books to Drakar och Demoner and this agrees with the vision the authors of the books claims to have.The results also shows that it is not only the language mistakes and the composition that makes the books hard to read, but also the choice of difficult words and badly formulated rules..

Sand pits as habitat for ground beetles (Carabidae) : does the area affect species number and composition?
Sand pits are a valuable habitat which can hold many sand living species including several endangered ones. As many sand habitats with exposed sand are declining, sand pits have a potential as a substitute habitat. This study was conducted to see what effect the area of a sand pit has on species number and composition of ground beetles (Coleoptera: Carabidae). Also, the effects of other environmental variables were tested, for example the proportion open sand, vegetation cover, sun exposure and tree cover. The study was conducted in the county of Uppsala in 2008 and included 13 sand pits with areas between 200 and 180,000 m2.

Klostridier och jästsvamp i ensilage ? orsak, verkan och samverkan
Yeast and Clostridia is a problem in silage for farmers as contaminated silage may result in poor animal health and milk quality. Clostridia can produce toxins that, when consumed, acts as neurotoxins, it may also cause blown cheeses if the Clostridia contaminates milk. The purpose of this study was to investigate the cause, effect and interaction of yeasts and Clostridia in silage. Clostridia are microorganisms which are strictly anaerobic and consume carbohydrates and protein in the silage. Yeast is a fungus that is facultative aerobic and feed on carbohydrates in the silage.
Bach and Improvisation - A research on how useful Bach is for improvising music
I wrote this thesis for myself and someone who would like to learn improvised music not from Jazz but Bach. I analyzed one composition by Bach, then I showed one example of using his idea to a Jazz standard tune. It was challenging for me to understand and analyze his composition as a Jazz improviser. To be honest I don't like to learn the music language from Bebop music but I like to play Jazz standard music. If someone would like to be good at playing jazz music, I think that it is important to know the music language in jazz.
Challenges and incentives for sustainable manure management in Russia
The Baltic Sea is threatened by eutrophication that largely is due to nutrient leaching from farmland within the catchment area. To solve this problem the surrounding countries cooperate within various configurations such as HELCOM and the EU-financed project Baltic Compass. Poor manure management in Russia has been discussed frequently the last couple of years.
A literature review of different types of reports and legal acts is the core of this degree project which has been performed in connection to two ongoing research projects financed by EU (Baltic Compass) and SIDA. It is supplemented with interviews with Swedish agricultural consultants and travel reports from two occasions when I had the opportunity to discuss with Russians active within the agricultural sector. Different hypotheses were investigated and discussed.
The environmental debate in Russia is quiet and there is a widespread approach that economic profit always trumps environmental concern ? a Soviet heritage that influence the Russian agriculture considerably.
The Russian legal acts on stable manure management focus mainly on sanitary questions and only secondary on nutrient leaching.
Biomassauttag vid delkvistat sortiment i klen gallring
The purpose of this study was to estimate the removal of biomass in connection with thinning operations in young stands that are dominated by small diameter trees. The economy of such operations depends on the products generated as well as the performance of the harvesting systems. Conversion tables designed to predict the outcome based on harvesting method was another goal of this study. Removal of biomass affects the Nutrient composition of the site. Therefore it is a purpose that this study will provide researchers with some variables that can be utilized when studying this aspect.
Trees were harvested and divided into bunches based on diameter.
