Ethanol produced from lignocellulosic biomass has the potential to become a promisingalternative to gasoline. In this work the simultaneous saccharification and fermentation (SSF)technology was applied for ethanol production from hardwood with focus on cell growth,ethanol production and contamination.The SSF was performed at PH 5.5 and 35°C for different suspended solid concentrations(8%, 10% and 12%) of pretreated birch slurry which contained 16 % total suspended solids.Two different hexose fermenting yeast strain (Ethanol Red) and pentose fermenting yeaststrain were used.Quantifying the concentration of chemical components and metabolites in the fermentationmedium demonstrated that glucose and xylose are the major fermentable sugars in the slurry.The higher load of slurry (12%) represents a higher content of carbohydrates and potentiallyhigher end concentration of ethanol. Moreover, more lactic acid is produced with the lowerload of slurry (8 % or 10 %), presumably due to a result of a less inhibitory environment forbacterial growth. In this context, acetic acid sticks out as the most important inhibitor withconcentrations of 15.2 and 12.5 and 9.7 g/l respectively in the 12 %, 10 % and 8 % (ofsuspended solids) trials. Using pentose fermenting yeast may lead to higher ethanolproduction, lower xylose uptake and lower lactic acid formation.

This project is about development of virtual drums for iPhone and iPad. The project aims to provide the company Toontrack AB with a good foundation to build drumbased apps. The focus has been on getting a quick response when playing and that user interfaces should be easy to use, intuitive and customizable. The result is impressive and both audio and graphics are of excellent quality thanks to good collaboration with Toontrack, that previously has developed drum-based software. The drum kit offers a variety of articulations and even the ability to play various dynamics, although the screens are not pressure sensitive..

Sheep breeding contributes not only with wool, hides, meat and milk but also with openlandscapes. The sheep?s wool is a good raw material thanks to a lot of different qualities as itis water rejecting and easy to form. The wool production today is concentrated to specificplaces in the world which leads to environmental problems and a distorted market. InJämtland, a province in Sweden, there is right now a staking going on for local production andrefining of wool in a project called Ullforum.

Peat litter is a soft material with high absorbency. About hundred years ago many farmers in Sweden used peat litter to their dairy cows. After the World War II the use of peat litter decreased and the farmers used more straw. Nowadays (year 2007), when it is harder to find straw and sawdust to buy, peat litter is advancing again. The purpose with this study is to investigate peat as a litter to dairy cows.

The purpose of this thesis is to investigate whether placement, using a special display, of ecological products, will have an effect on consumer buying behaviour and thereby sales of these products. When talking about sales we refer to the amount of ecological products that are being bought, habitual and unplanned, as a response due to the placement of the products in-store. To further elucidate the purpose, the thesis will focus on if the placement of the products itself will have an impact on the customers? attitude towards buying ecological products. A deductive approach was applied where we did a quantitative study using triangulation to receive data to reveal if the placement of ecological products had any effect on the sales of these products.

The aim with this thesis is to make a comparison between forcing tulips in a hydroponic system and the forcing off tulips that have been planted in soil. The results are mostly based on interviews with six Dutch and one Swedish tulip forcer and the managing director at the Horticultural Research Centre, Proeftuin Zwaagdijke, in the Netherlands. There are benefits and disadvantages with both methods. Tulip bulbs planted in soil seem to get a brighter colour after forcing, compared with those forced ?in water?.

The increased popularity of e-books in the Swedish publiclibraries started a debate in newspapers and library journalsbecause of the increase in costs, which this popularity hadled to. The main subject of the debate was the businessmodel provided by the e-book vendor Elib, which accordingto some ruins the libraries financially. In this thesis, opinionarticles have been analyzed using a theoretical model ofcultural politics by the Danish Library and Informationscience researcher Dorthe Skot-Hansen. The results of thestudy showed that people from the library field, publishersand authors were the ones contributing to the debate. Theanalysis of the articles showed that the model of culturalpolitics which consists of four general motives: socialchange, education, economic growth and entertainment wasvisible in the articles.

Bakgrunden till studien ?r att unders?kningar och statistik visar att elever med utl?ndsk bakgrund i Sverige har st?rre utmaningar att f?rst? texter j?mf?rt med elever med inhemsk bakgrund. Att kunna avkoda och f?rst? en text har en avg?rande betydelse f?r elevernas skolframg?ng. En god l?sf?rm?ga ?r dessutom av central betydelse f?r att kunna delta i ett demokratiskt samh?lle.

In Sweden, grass is the single largest crop grown. Nearly 1 000 000 Ha grows on the fields, this is primarily used as feed for livestock. To get a good seed, you need to handle the crop carefully from planting to delivery. The part that I have been interested in, is how to dry the harvested seed with out destroying the growth in the small seed. This is very easily done if you aren?t careful during the drying period.

In July 2011 the journalists Martin Schibbye and Johan Persson are arrested in Ethiopia when on a mission to report the activities of the oil exploration company Lundin Petroleum. Following a trial, closely observed by media, the two journalists are convicted to a prison sentence of eleven years. The Swedish Minister of Foreign Affairs, Mr. Carl Bildt, is now to act on their behalf to preserve their rights as Swedish citizens. However, doubts are raised as to whether Bildt has a conflict of interest because of his former engagements as a board member in Lundin Petroleum.

Livestock of pastoralists provide meat, milk, blood, dung and are useful for transportation purposes. In semi-arid and arid areas with very low precipitation the herder must often walk far distances to feed the livestock. This affects the animals? production, especially of milk. Previous studies have investigated how to improve milk production in terms of milking strategies in cattle.

Sustainable development is a concept that has been interpreted in a multitude of ways in different contexts. This essay argues that the discourse of "ecological modernization" has strongly influenced the way in which the concept of ?sustainability? has been constructed in Swedish environmental policy. This interpretation of the concept of sustainability offers the possibility of combining economic growth with ecological sustainability which stands in contrast to the assumptions of Deep Ecology and Green Theory. The aim of this essay is to explore how the concept of sustainability is being formulated in environmental policy both on a national level and in the city of Malmö.Considering these issues in a specific context, this essay focuses on city planning that is as an important instrument to promote urban sustainability both on national and local levels.

All over the world the waste from human society is causing problems. In developing countries, large cities are polluted through huge amounts of wastes and people are forced to live very close to open deposits. Lima, capital of Peru, is no exception. The countryside in Peru has also a great challenge to face concerning the waste issue. Children and adults suffer from infectious diseases and contamination of the nature occurs as well. One solution to handle organic waste is to compost, which means a controlled decomposition of organic waste under aerobic conditions at certain temperatures.

Ethanol for automotive purposes is an issue much debated and researchers disagree about the benefits of bioethanol. Converting energy-rich crops into ethanol suitable as motor fuel is a complex process and continuous development and improvements of processes and material used are important steps in the work of developing environmental friendly fuels. Grain is usually preserved by drying which consumes a lot of energy. Alternative storage of high-moisture grain in airtight storage systems reduce the energy required to produce bioethanol and studies have also shown that ethanol yields are increased more than 10% in ethanol fermentations of moist grain compared to dry. Airtight storage is often not perfectly airtight so biocontrol agents are necessary in order to preserve the grain.
