Individual cellulose ?bers were studied to identify the transport and absorbtion phenomena as well as the in?uence of drying. A Chalmers University of Technologydeveloped method within ESEM (Enviromental Scanning Electron Microscope) has been used in this study. The results from the laborations gave the following conclu-sions: The transport of water occurs in ?bers in the ?ber wall surface and the lumen.

In times of increased flooding, enhanced by climate change, polluted stormwater poses an increased threat to the environment through contaminated water entering waterways. Bioretention utilizes natural processes in soil and vegetation to treat pollutants and combat this threat. Biochar produced through pyrolysis, has a high Cation exchange capacity (CEC) and could therefore increase treatment in bioretention systems. This research applies a literature review, interview, and a model to explore the benefits and disadvantages of biochar in order to specify a soil-mix through an understanding of the production process and preferred appliCation rate. High purifiCation through CEC, increased water holding capacity, and carbon sequestration being the benefits discussed.

This paper compares and discusses teachers´ nonverbal communiCation in the classroom. The purpose of the study is to find out what the teachers´ nonverbal communiCation looks like in the classroom and with that information increase teachers´ awareness of nonverbal communi-Cation and its impact on the teaching. Ten teachers at the upper secondary school have been observed for twenty minutes when having a lecture. The result shows that the most common nonverbal expressions are hand and arm gestures used to enhance what is said by the teacher. The result also shows that the nonverbal communiCation is similar with all observed teachers.

Within telecommuniCation and routing of tra?c in IP-networks a protocol named?Open Shortest Path First? (OSPF) is widely used. This means that a server dealswith the routing over a network with given weights by calculating shortest paths touse for routing. If we assume that a desired tra?c pattern is given the problem isto ?nd out if it is possible to set the weights so that the desired tra?c pattern is apart of a shortest path graph.

Milk fever, or parturient paresis, is the second most common disease in Swedish dairy cows. The disorder is associated with the onset of lactation when some cows are unable to meet the metabolic demands of calcium to support milk production and therefore develop a state of hypocalcaemia. Clinical hypocalcaemia (milk fever) may lead to coma and death in severe cases but subclinical hypocalcaemia has also been shown to have negative effects on e.g. feed intake and production and to increase the susceptibility of the cow to develop secondary diseases. The nutritional strategy applied precalving is of great importance in preventing milk fever and e.g.

Many students in the Swedish and Norwegian compulsory school do not have quali­fi­Cation to search for further eduCation. There is a large part of those pupils who have a different native language than the country?s majority language. These students? possi­bi­lities to a fair and equal eduCation is regulated in national laws and regulations of school activity, the so-called governing documents. The purpose of this study is to compare Norwegian and Swedish governing docu­ments regarding eduCation for pupils with another native language.

The purpose of my research has been to analyze the communi-Cation of three cultural heritages and how they are being ex-posed on their respective webpages. The essay has also touched the subject as to how webpages can, through marketing of cul-tural heritages, create a connection to the marketed loCations and their cultural environment. A phenomenon you could call ?creating a loCation?. My study has also resulted in an under-standing of how historical sites as cultural actors position them-selves to attract visitors to the loCation.

The Swedish preschool combines both eduCation and care from a holistic point of view. This makes it even harder for both parents and the educators to make an objective evaluation on their own preschool. In Sweden we are proud to have one of the world?s best preschools. It is regulated by the government and is obligated to undertake critical evaluation from the state and the parents that are the consumers of these services.

AcidifiCation is a central concept in the environmental debate. The effect of acidifiCation of the soil is a matter of a decreasing amount of Cations and thereby a decreasing ability to resist a supply of hydrogen ions to the soil. AcidifiCation has gradually increased in the O horizon in Västerbotten over a 30-year period from the 1970th to the 1990th. The aim of this study was from inventories of The Swedish National Forest Soil Survey and The Swedish National Forest Inventory explain and quantify the acidifiCation that has occurred in the O horizon of two regions in the north of Sweden. Data from SMHI, The Swedish Meteorological and Hydrological Institute, has also been used.

The goal of the society to increase the proportion of renewable energy has led to an increased demand of bioenergy e.g. forest biomass. However, there are concerns that removal of biomass will lead to decreased base Cation concentrations in the soils and acidifiCation of streams. In order to find in which types of landscape removal of branches and tops could have such negative effects, this study aims to analyse the relations between pH-sensitivity and landscape variables in the Bothnia Bay water district. GIS and digital geographical data were used to analyse the landscape in subcatchments.

This thesis presents the results of the implementation and evaluation of two machine learning algorithms [Baz98, GB97]based on notions from Rough Set theory [Paw82]. Both algorithms were implemented and tested using the Weka [WF00]software framework. The main purpose for doing this was to investigate whether the experimental results obtained in [Baz98]could be reproduced, by implementing both algorithms in a framework that provided common functionalities needed by both. As a result of this thesis, a Rough Set framework accompanying the Weka system was designed and implemented, as well as three methods for discretization and three classi Cation methods. The results of the evaluation did not match those obtained by the original authors.

In order to make take-off and landing procedures possible at an airport, an organized allo- Cation of slots is necessary. How these slots shall be distributed among airlines is, at pre- sent, governed by the European Parliament and Council Regulation (EEC) No 95/93 of 18 Janu- ary 1993 on common rules for the alloCation of slots at Community airports. It is important for the air- lines to be allocated a beneficial slot. Hence it is of great interest for the airlines to ex- change and transfer the allocated times among themselves, a form of secondary market. Whether such practices are allowed or not is not regulated by specific detail in the regula- tion, which leads to legal uncertainty.

The purpose of this study is to investigate the forest managers view of the edu-Cation at the School for Forest management at SLU and the first years of em-ployment. Surveys were sent to batches 05/08, 06/09 and 07/10 a total of 136 question-naires were sent out. 80 people answered the survey, this gives a response rate of 59 percent The former students rated according to a 9-grade scale how satisfied they were with the different courses they had attended during their years as students at the school. The courses in mathematics and statistics got the highest marks with an average of 7.3, while the entry-level course in law only got an average of 4.6. A major part of the former students had in the questionnaire enquired a leader-ship course and a business course with focus on negotiation techniques during their eduCation. There is a wide variety of employment opportunities for the graduated students. Timber buyers and forest managers or planners are just a few positions that for-mer students now possess. The study shows that there is a big difference in the first introduction to a new work place depending on where the student got hired.

Simulation is a vital tool during development of JAS 39 Gripen, since money and time can be saved.The Auxiliary and Emergency Power System, AEPS, is a subsystem of the secondary power system in Gripen. It has the function of providing the aircraft with electrical and hydraulical power before activation and after deactivation of the main engine. The system also functions as backup in case of a safety critical problem in the main power supply system. The system basically consists of a control unit and an auxiliary gearbox. The gearbox is driven by an air turbine.
