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.

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.

The purpose of this investigation was to study what students in in the first year of the social science program in high school think about the guidance they had access to during their time at primary school. This is to ensure that it the guidance students are entitled to and contribute to the development of the business. The survey was conducted at two different high schools in southern Sweden. A total of 57 students participated in the survey. The results show that 46 and 29 percent of students at the two schools did not feel they had the information they needed for their upper secondary school The results proving what previous research reached that students selection process can lead to stress and uncertainty associated with the choice to high school. The results of the present study showed that girls in particular have high standards for themselves and experience stress and anxiety associated with their selection to a greater extent than boys.

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.

Addressing increasing global environmental problems requires greater resource efficiency, and one way of working towards this is through industrial symbiosis. Industrial symbiosis means that companies collaborate through sharing of resources for collective benefits. The documented benefits of working with industrial symbiosis indicate that there is potential for companies to operate commercially with facilitation of industrial symbiosis. An interesting company to study within this context is Econova. Econova operates within the recycling and gardening industry and has been identified as a possible catalyst for industrial symbiosis.

The design regulations of Boverket (BKR) have long been the mandatory standard for construction design in Sweden. However from the end of the year 2010, the BKR will be replaced by the European standard Eurocode (EC). The transition to EC has been delayed and it is not until the second of May 2011 that the use of EC will be mandatory. Because EC and BKR differ from each other it is highly interesting to investigate and explain these differences.The purpose of the thesis is to compare the two standards and investigate how they give different results or not for the dimensioning of structures of steel with associated loads. The current project HVC (Pets Science Center) in Uppsala is used as a model for the design of the steel structure used in this study.

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.

The official statistics on communication and transports in Sweden is administered by Statens Institut för kommunikationsanalys (SIKA). SIKA?s commission includes production of statistics on the Swedish vehicle fleet. These statistics provide important information tofinancial institutes, ministries, industry and mass media among others. Furthermore, the vehicle statistics include measures of comparison between different counties and municipalities.

Social networks have increased significantly during the latest decades, but what does the cooperation include and how does the network processes look like? Networks are not specific for communities in the 2000?s or for that matter human organisations, but the ability to build networks and introduce more actors to the organisation have become easier with today?s communication technology. The study is about the Norrköping Municipality membership in the transnational network Sweden Emilia Romagna Network (SERN). It gives an insight into how networking and cooperation can be seen by politicians and officials, based on mission statements and the reason why a municipality choose to participate in transnational networks. The study aims to examine how Norrköping Municipality uses the SERN network and what the network have resulted in since the beginning of the municipality membership in 2005. It is a qualitative study which involves interviews with officials and politicians from the Municipality of Norrköping and textual material from SERN?s strategy documents and policies.

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 the medieval ruling catholic time the church walls was swarmed with programs of pictures with religious motives there the animal figures rich symbolics was significant first and foremost for the illiterate. Principally the inspiration comes from the antiquitys pagan world of fables and bestiary Christian world of symbols with the bible as the essential source. The essay describes six of the most common animal symbols who occur; dragon, the sneak in the Paradise, mouth of hell, lion, the fox as a preacher and the devil.To attain to a discussion about why just animals are used as symbols for human characteristics in the medieval church art instead for human beings as it's actually be about, I have studied bestiary and other literature about medieval churchpainting to get an understanding about the history of ideas about the thoughts of the time and about symbolics of animals, worth and how the Christianity have had an influence on the pictures.I have used Johannes Rosenrods church pictures from Tensta church in Uppland from 1437 as an exemplification but also mentioned other unknown painters who used similar animal codes and motives.It's plausible that the purpose of the animal figures was both religious and political, which was used by both the spiritual and the worldly authority so they could keep their dominance over the peasant. The figures was simple to read and remember and they made a deep impression on the people together with the sermon. The churchgoer get so to speak a sound- and image experience, a medieval reality who impress their world of ideas.When it's about the artistic formation of religious expression and characteristics it was undoubtedly a great advantage for the artists to use an animal code like a schemata.

Demands on businesses are constantly increasing and the competition in the market-place is becoming ever tougher. To gain the long-term confidence of customers, not only the best businesses, but also the best supply chains are required.Volvo Cars is experiencing a changing competitive situation and their retailers are having trouble stocking the right spare parts. Shorter product life cycles and the growth of Volvo?s product program result in an increase in the number of spare parts to be stocked. In order to adapt to market trends and meet customer demands, Volvo has developed the LDC model, establishing a number of regional warehouses in strategic locations in Sweden, de-signed to supply spare parts to the regions? retailers through so-called Vendor-Managed In-ventory (VMI).The purpose of the study is to examine Volvo personbilar Sverige?s (VPS) motivation for a modified customer-service strategy through LDC.

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.
