There is a great need to reduce nutrient leaching from arable land into lakes and oceans. By using several different types of models it has previously been possible to describe nutrient losses in a catchment area with a minimum unit of sub-catchment level. At present, it is instead desirable to model a smaller catchment with an opportunity to re-connect the results to the corresponding fields in the catchment. Such models already exist but they are not fully able to properly describe Swedish conditions and land characteristics in our region.With the approach of creating such a model, SLU has developed a project with this work as its first stage. The model is expected to be created under the working name SWE-model which stands for Soil Water Environment and is in this first stage supposed to apply the SOIL model in catchment scale. During the procedure to describe the first step in the process of developing such a model adapted to Swedish conditions and which works in the catchment scale with an area of about 10-30 km2, focus has been set on calculating the transport of water flow from different hydrological response units. Regardless of the processes occurring in the soil after the water has been added, it is assumed that all the water which flows from each simulated unit is drained.In the first step the hydrologic response units were identified based on land use and soil type in the study area. With the help of a script with functions that retrieve and transform data, certain units were chosen for simulation. The script was also created in this project. Finally, the model results were aggregated and summarized for each unique unit, for each sub-catchment, and also for the whole catchment.From the results it is possible to see similarities in the flow dynamics between modeled and measured data. The efficiency coefficient has been calculated to correspond to the mean of the measured values for the whole simulation period. With an automated calibration process the model should be able to perform better. The volume error gives an indication of overestimation from the model..

Background: Exercise dependence is a behavior where some people get very strong feelings for their training. This dependency becomes a problem when it affects individuals? life in a negative way. Individuals with low self-esteem have been found to have an increased risk for exercise dependence. Self-estem is associated with Self-compassion, which is to have compassion with oneself in pain and difficult periods.

How teachers teach children with attention difficulties. This is a qualitative interview based on the experiences of four teachers. I want this study to examine teachers' experience and views about ADHD diagnosis. I would also like to find out what teachers do and think about the practice which surrounds students with ADHD. How to formulate and think of four active teachers about ADHD? What are the implications of the diagnosis perceive the four teachers interviewed that the diagnosis must for students? Among the measures that consider the four teachers interviewed are most effective for students with ADHD because they provide an equal education? Those questions are addressed to specifically learn about how they proceed in their activities.

The borehole heat exchangers of today suffer from poor thermal and hydrodynamic performance. The purpose of this thesis is to improve the performance of ground source heat pump systems and thermal energy storages by increasing the energy efficiency of the borehole heat exchangers. For this reason, the annular coaxial borehole heat exchanger (CBHE) has been analyzed. This type of heat exchanger is interesting in terms of both thermal and hydrodynamic performance. A model has been set up in the program Comsol Multiphysics in order to investigate the heat transfer characteristics along the borehole.

The trotting in Sweden has a good reputation in an international view, both in the perspective of success and how the sport is managed with focus on security, animal protection and animal welfare. A large number of equipment details are fitted on the horses during training and competition. The Swedish law of prevention of cruelty to animals regulate training and competition with racehorses, and propose to protect horses from unnecessary suffering. The equipment permitted in races is regulated in Tävlingsreglementet (The Regulation of Competititon) and in the regulations of equipment, that the Nordic Regulation Committee and Nordic Animal Welfare Committee have worked out. Due to training and competition the equipment must even meet the Swedish law of prevention of cruelty to animals. However, the behaviour or the senses of the horses is often affected by the equipment due to the way the equipment corrects, modifies, restrains or reduces the behaviour of the horse, which may cause the horse stress or discomfort.

Smartmobilens användande har successivt ökat och blivit en central del i vår vardag. I och med detta har antalet olika applikationer ökat och numera finns det en mängd olika typer av applikationer som tillfredsställer användarens behov. I den här studien har vi därför försökt ta reda på om träningsapplikationer har förmågan att motivera användaren vid träning. Vi har observerat fem kvinnor och tre män, med varierande erfarenheter av träningsapplikationer, som har deltagit i en fyra veckor lång studie bestående av två faser. Under Fas 1 har respondenterna laddat ned två valfria träningsapplikationer som de testat och under Fas 2 har de använt en specifik applikation.

Långvarig stress ökar risk för ohälsa och sjukfrånvaro, med negativa konsekvenser för individ, organisation och samhälle. En preventiv metod för stresshantering är Acceptance and Commitment Training (ACT). Syftet var att med en randomiserad, kontrollerad studie undersöka huruvida en kortvarig ACT-intervention påverkar stress och generell psykisk hälsa hos socialsekreterare inom Stockholms stad (n=106). Bortfall hanterades med intent-to-treat-analys. Vid förmätning rapporterade två tredjedelar av deltagarna hög stressnivå (PSS?25).

Today there is a research project undertaken by the Swedish University of Agricultural Sciences along with Wången (a highschool specialized in trotter training), which focuses on trotting horse training, performance and health. The project investigates how exercise intensity and feeding strategies affect the development of growing horses. The project includes two groups of horses where all 16 horses are fed in the same way. One group of eight individuals are trained 100% compared to conventional training and the other group are trained 20% less than the other group. All horses are trained twice a week and are out at pasture beyond that.

This is an examination report in physical education. It focuses on the relation between excercise and nutrition and how this relation works in an icehockeygymnasium in a midsized city in Sweden. The training ratio for the students are 11-12 times a week which indirectly means that the nutricion is very important to them so that they have the strength to manage both training and school. In this examination report you can read about how the food is composed and how many meals the students are offered through their education program. The persons that I´ve interviewed are the head coach, the president of the school restaurant and three students.The students have practise in the noon two times a week, on Tuesdays and Thursdays.

Bakgrund: Tidigare studier har visat att barn har sämre styrka i överkropp och bål samt är mindre fysiskt aktiva nu än tidigare, detta skulle kunna medför en ökad hälsorisk framförallt på längre sikt.Syfte: Att undersöka om ett pass med 4 min Tabata intervaller med stabiliserade övningar, varje skoldag under en 6 veckors period gav någon skillnad på de fysiska testerna och gav en ökad stabilitet och styrka hos barn i åldern 7-9 år.Design: Studien genomfördes som en interventionsstudie med en kvantitativ ansats.Metod: 42 barn varav 23 flickor och 19 pojkar i åldern 7-9 år deltog i studien som genomfördes på skoltid i klassrummen. Utöver studiegruppen användes 13 barn som kontrollgrupp de genomförde enbart de fysiska testerna före och efter studien.Resultat: En signifikant ökning av antalet push-up (P<0.05) och push-up (knä)(P<0.05) kunde påvisas efter studien.Konklusion: De fysiska tester som visade signifikanta förbättringar hade liknande övningar inkluderade i Tabatastudien..

Severe floods caused by heavy autumn rains in year 2000 raised the question whether measures to reduce the damage from high water levels, in the area surrounding lake Glafsfjorden and along the river Byälven down to lake Vänern, are possible. One option is to reduce flow resistance along the river and thereby lower the maximum water level a given inflow would cause. Good knowledge of hydraulic and hydrological conditions is necessary in order to estimate the effect of such flow-reducing measures. In order to quantify such effect a 1-dimensional hydraulic flow model has been set up for the river Byälven using the software package MIKE 11. The model is more detailed, especially concerning topography and bathymetry, than earlier models used for studies of the river.

Abstract This examination work is about the role of physical activity for students with concentration difficulties. The purpose of this work is to describe educators experiences of how students with concentration difficulties are affected by physical and motor activity during school-time in primary school. In the work I assume from my questions that are: How do educators experience students with concentrations difficulties? Do educators think physical and motor training during school-time matter for the students learning processes? How? Do students with concentration difficulties have other possibilities than other students regarding physical and motor activity during school-time? I am using a qualitative interview method for answering my questions. The interviews are conducted in collaboration with three educators in a medium-sized Swedish F-6 school.

Background: Officers in the Swedish Armed Forces educates their soldiers in various skills and arenas. The Officers get their educational training in officer training courses conducted by the Swedish Armed Forces or the Swedish national defence college. The aim of this study was to find out how the cadets, belive that they are formed into educators, their views on the literature being used in the Swedish armed Forsces, and their views on leadership and educational science.Methods: The data for analysis were collected in spring 2010, by use of a questionnaire among cadets studying the tactical/operational program Ta/Op 07/10 at the Swedish national defence college. The respons rate was 69, 6 %.Results: The majority of the cadets thought that experience was the most important factor in becoming a good educator. Most of the cadets also thought that the literature being used by the Swedish armed forces was good, however, few cadets stated that they will use the material for reflection on their own teaching when working as officers.Conclusions: The Cadets had a positive attitude towards the educational philosphy and literature being used, but few will use the literature in reflecting on themselves as teachers.

In this work, a method was developed and evaluated for calculating the life of welds under the influence of fatigue loads from a vibration environment. Typically, a shaker table is used for testing a component against vibration loads. The shaker table creates a vibration environment that is defined in the frequency domain by a power spectrum.Similarly, a virtual vibration table can be used to calculate the same type of load environment, which can then be used to calculate the expected lifetime. The benefit of this method is that it can be used in design, as well as in simulation of tests before physical verification tests are carried out.Today there are methods for calculating fatigue life of non-welded base material, but since many components contain welded joints, there is a need to apply this method to those types as well. To achieve this, the thesis combines two different areas, which together provide a method for fatigue assessment of welds using a virtual shaker table.The methodology is carried out by modeling the component, and its welded joints, in a finite element program.
