Over the past ten years, the pupils' performance and grades has fallen and the number of competent to high school has decreased gradually. The Swedish school has been criticized and the role of the teachers has been questioned, among other by the media. In autumn 2007 Johannesskolan, one of Sweden's tenth worst schools replaced the ordinary teachers of Class 9A against eight of the country's "main" educators with the goal of the class to become one of Sweden's third major. The teachers have the autumn term in which to achieve the goal and the outcome will be measured by national tests in core subjects Swedish, English and Mathematics. The aim of this paper is to examine the role of the teacher's leadership in relation to the pupils' social and intellectual development, and identify common leadership of these eight educators.

The work has been carried out in cooperation with the company Zenit Design in Malmö. The project's goal was to restore, improve and produce an ozone generator. During the project, the authors sought relevant literature in databases, been in contact with US suppliers of fuel cell membranes, Asian suppliers for the processing of Teflon and Titanium parts in mechanical engineering and Swedish suppliers of various standard components. The authors had access to a temporary lab at Zenit and electron microscope at Halmstad University where material tests were performed. The authors have also had access to measurement equipment to measure amounts of ozone.During the work, the authors have mapped how an existing ozone generator works and then have their own development.

ABB Surge Arrestors in Ludvika have for a long time had a problem to keep the moisture at a steady state in the production of their ZnO-powder, that is used to produce varistors.Some black-box models of the spray drying process have been designed and evaluated to find a solution for the problem. After evaluating the collected data it has been found that variations in the supply voltage causes control difficulties for the operator. A cascade control system was designed, consisting of three PI control loops designed with lambda tuning. The disturbance in the supply voltagewas used as a feed forward in the control system.At the end of the project the control system was installed, and tests were made to verify the functionality of the regulator. It was shown that most of the variations in the moisture of the powder could be eliminated using small resources, through purchase of a process controller and four power meters.

There are many aspects which must be taken into consideration when studying individuals? need of exercise. The study investigates if impulsivity and Health Locus of Control affect the continuity of physical practise. The main presumption was that individuals with high impulsivity, high Powerful Others and high Chance Health Locus of Control, would have a significantly harder time to maintain a continuous physical activity. The survey used two standardized tests to measure impulsivity and Health Locus of Control and in order to be able to measure the insensitivity and the periodicity of physical exercise, a test was developed by the authors.

In the current study, the aim was to investigate whether tail posture and motion can be an indicator of the emotional state of pigs and if the tail posture of the pig is affected by social breeding value (SBV), coping style and/or housing. Emotional state can be defined in two dimensions: valence and arousal. Two batches of 96 finishing pigs were studied in a one generation selection experiment with a 2x2 set up and were housed in a barren or straw bedded pen. In each pen, 6 pigs (3 male, 3 female) were housed. A back-test was done to determine the coping style of the pigs with two categories; high resister and low resister pigs.

This report describes an bachelor thesis work which is performed in cooperation with SVIA that develops and sells automation solutions for the manufacturing industry. The thesis purpose was to evaluate the machine FeedLine to find opportunities for improvement in the product?s design that could lead to more standardization and thus improving the efficiency of manufacturing and assembly.Based on these basic issues suggestions for improvements were developed:How can the design of FeedLine be improved to facilitate the assembly?Can more standardization be imposed on FeedLine?s design to enable more stocking of standard components?An initial pre-study was conducted to evaluate FeedLine?s to find opportunities for improvement in its overall design. During the pre-study staff at SVIA and two of its clients was interviewed. Based on information gathered during the interviews and observations by the authors improvements was amendments.

Test for Auditory Comprehension of Language -3 is an American picturebasedtest developed to examine children?s auditory comprehension of language.The aim of the study was to create a translation and to examine if the test wouldcontribute to the information about a child´s language comprehension received bysimilar tests that are used today. In the present study the test items were translatedinto Swedish. The translation was evaluated with 32 children in three different agegroups at a school in central Gothenburg. A linguistic examination of thetranslation and a list of the grammatical structures that are tested were made.

In this essay I examine the causal relationship between confidence in institutions and growth in Sweden 1989-2002. By examining the causal relationship between these two variables, valuable indicators of the causal relationship between trust and growth can be obtained. The institutions which are used in this essay are chosen according to the theory on institutions for public administration building trust and social capital. The chosen institutions are primary schooling, the police and medical service. A Granger causality model is used to measure the causal relation and the results from the tests show that there is no causal relationship between growth and confidence in institutions.

The problem presented in this report is that of finding a method to calculate the lift force from a single-element airfoil of arbitrary shape. A number of restrictions are used in order to simplify calculations while retaining reasonable accuracy. The problem is solved for the two-dimensional case only and no finite-wing effects are taken into account. Furthermore, inviscid and incompressible flow is assumed. The method used to solve the problem is the vortex panel method, with vortex singularities distributed over simplified airfoil geometry.

This thesis has been written at Linköping University for the company Instrument Control Sweden AB (ICS).ICS is a small company located in Linköping that develops software and hardware for Unmanned Aerial Vehicles, UAV. At present, ICS has a fully functional autopilot called EasyPilot but they want to reduce the autopilot?s size to make it more attractive.The purpose of this thesis was to investigate if it was possible to reduce the size of the autopilot and how, in that case, it would be done. It was also necessary to examine whether the old processors should be replaced by new ones and how hard it would be to convert the old software to these new processors.To succeed with the goals many of the old components had to be changed for new, smaller ones. Some less necessary parts were also completely removed.

Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.

Author: Karl LarssonTitle: Samverkan mellan skola och socialtjänst ? en studie i attityder och kunskapThe overall purpose of the studie has been to explore inter-professional work between social workers and teachers. The main focus has been on the link between attitude and knowledge. Attitude and knowledge has also been tested for any connection to age, gender, what kind of a teacher you are and for how long you have been a teacher.The collected data has been analyzed in a descriptive part, one part with correlations and in one part with t-tests. The terms samsyn (consensus) and attitude has been reviewed in its connection to the results.The study shows a significant correlation (0.222*) between knowledge and attitude.

This thesis which is about working with mathematics teaching has no effect/impact on performance and understanding of pupils. The study is intended to gain insight on working in mathematics education which has an impact on performance and understanding of students who are ethnically Swedish and foreign ethnic. In order to compare the ethnic Swedish and foreign students of ethnic understanding, I judged from their performance on the tests taken in year three. The qualitative approach permeated the work, both interviews and observations which were included in the survey. The qualitative study was chosen to get an understanding of how mathematics teaching is conducted in two different areas.

As the quality of internationally competing horses is increasing, a debate concerning the breeding goal of the Swedish Warmblood horse has arisen. Some people claim that the breeding goal should be divided into two separate goals in the future; one for show jumping horses and another one for dressage horses. At the same time others claim that since the largest group of people using the Swedish Warmblood horse today is amateur riders, the needs of these riders should be taken into a larger consideration in the breeding program. The largest emphasis in this matter is on the horses? temperament. The objective of the study was to investigate what the majority of the Swedish horse people think about a variety of questions concerning today?s breeding goal of the Swedish Warmblood horse.

This report is about the experiments with mixing of the separated water and the vacuum pump seal water at Hellisheiði power plant. This is done to prevent silica scaling and clogging in pipes and reinjection wells as well as eliminating vacuum pump seal water from the plant. The experiments were done in four stages: the first stage comprised of tests with different flows of separated water at 70°C, the second stage was carried out by mixing the separated water at 70°C and the seal water with different amounts of the seal water, the third and the fourth stages were like the first and second but with the separated water at 120°C. The results show that this method is good if the mixture is around 50/50 separated water and seal water, to control the silica scaling in the separated water and to be able to reinject the seal water with the separated water. This does not eliminate the silica scaling in all of the separated water because the amount of separated water is much more than the amount of seal water that comes from the plant. .
