Skogsbränslets fraktionsfördelning

This study has analyzed particel size distribution and needle content in chipped logging residuals (branches and tops) delivered to the district heating plant Ryaverket in city of Borås, Sweden. Two fuel assortments has been analyzed: Chipped logging residuals from pure softwood and from mixed fuel (connifers and broadleaves). The samples has been sieved at Linneaus University laboratory.The study of particle sizes indicates that only 53,2 % of delivered fuel is within the fuels specification (7? 45 mm). The needle content is in this study 12,4 % (dry mass) which is higher than expected..

Kvalitetsarbete i grotskotning

This study was carried out at the request of the Swedish forest company Sveaskog which is an important producer of logging residues (branches and tops) intended for energy production. The company wanted to increase the average dry content to 60 percent in their delivered logging residues. At the time when this study was initiated, the dry content in the chipped logging residues originating from the Bergslagen district was at 52 percent. The aim of the study was to find out how windrows of logging residues could be arranged in order to help obtain desired properties such as increased dry content. Sveaskog had developed a system for evaluation of windrows and a standardized form was utilized to describe different properties of the windrows.

Att skilja på sak och person - Hur ökad personifiering i media kan leda till bättre politisk kunskap hos mottagarna

Mass media is becoming more and more personalized and despite common ideas it could actually be a good thing. Instead of affecting the actual content of news coverage it might only have an effect on the way in which news are presented. Famous politicians more regularly become symbols and synonyms for their parties or for the government and are being used to create interest in the beginning of articles.Those are the results from a content analysis of the newspaper coverage of the Swedish parliamentary election in 1976 and 2006 in which the scientist categorized each article in one of four ideal types, counted quotes and analyzed whether personal names were interchangeable with party names without affecting the content. All three methods showing that it is the presentation, not the content, which has been personalized.At the same time, psychology-science tells us about the human brains associative learning processes, where memorizing becomes far more efficient when the information can be connected to an already known person. Increased personalization of news might therefore increase the political knowledge of the receivers..

Fint och fult i film : En studie av finkulturell och populärkulturell diskurs i svenska filmrecensioner

The discussion about high culture and popular culture in our society has been going on for decades. In few places is it as loud as within culture journalism and the critics? society, where the question of what is good taste and what is dumb entertainment constantly gets brought to the surface. Film is a particularly vulnerable area, since it is such a universally appealing and rather young medium. In America and England several studies have been performed of the reviewing society and reveiwers? use of high and low art-discourse in their writing.

Skillnader i kommunikationsstil mellan individualistiska och kollektivistiska kulturer

The purpose of this study was to investigate if preferences for high- and low context communication differed significantly between individuals from individualistic and collectivistic cultures, living in a multicultural environment. A quantitative survey was used as method and the survey was answered by 150 students at Jönköping University and Uppsala University. Two self-assessment scales, obtained from previous studies were used to measure the degree of the two cultural dimensions and communication styles. Two multiple regression analyzes were performed to investigate the connection between collectivist cultures preference for high context communication and individualistic cultures preference for low context communication, that has been found in previous studies. Two ANOVAs were also performed to investigate differences in communication style depending on sex and length of stay in Sweden.

Hur har handeln med omvärlden påverkat det effektiva utbudet av arbetskraft i Sverige? - faktorinnehålls-analys för år 1995 och 2000

Through trading with countries that have a relative aboundant supply of labor, Sweden changes it's effective supply of labor, in a Factor Content perspective. This essay does two Factor Content analyses, one for year 1995 and one for 2000. The first comparison of these analyses shows that Sweden exports about 27 600 labor-years more year 2000 than 1995. However, since Factor Content analysis arguably underestimates the imported labor, some assumptions are made in order to correct for this. This correction has great importance for the final analysis.

Möjligheter att minska kväveutlakningen genom att anpassa kvävegödslingen till variationer inom stråsädesfält

Due to excess precipitation that cause runoff, all soils in Sweden naturally leaches nitrogen.High leaching from arable land is an environmental problem when the runoff reacheswaters. In the international agreement, Baltic Sea Action Plan, the aim is to reduce therunoff of nutrients. Sweden has agreed to reduce its load of e.g. nitrogen to the Baltic Sea.One of the proposed measures is an increased use of site-specific N-fertilization, which hasbeen shown to increase nitrogen use efficiency and therefore also reduce the nitrogen runoff.Either yields are increased with the same total amount of nitrogen, or the total quantityof nitrogen is reduced with preserved yield levels, which is profitable for the farmers.The dynamics of nitrogen leaching differs between top dressing applications above orbelow the economical optimum. There is a consensus about a difference in the dynamics,but not about its magnitude.

Ingefäras antiemetiska effekt vid cytostatikarelaterat illamående : En litteraturöversikt

Aim: The aim of this study was to determine whether or not there is evidence for the usage of ginger as an antiemetic in patients experiencing chemotherapy related nausea, based on available scientific literature.Methods: The original articles were found by using search engines PubMed and CINAHL. The selected articles were then analyzed based on their content, quality and results.
