In recent years, more of high stakes (National exam- NP) have been introduced in Sweden and now (2015) the government has decided that the NP in social sciences- and natural science in 6th grade is optional in order to reduce teachers' administrative burden. Based on these reforms, to have more tests in more grades and also on the decision to remove the test, the purpose of this study is to examine how teachers perceive the work of the (NP).A quantitative research was done in the form of questionnaires. The study was based on questionnaires regarding the time for working with the NP and of the intention that the NP should be a support for teachers.The result of the study is linked to school development and the constructivist theory of learning. The results show that teachers perceive work with NP takes a lot of time, where as the time for administration seems to take slightly lesser time than the time for assessing the exams. The results also indicate that teachers perceive NP as supportive, mainly in relation to the curriculum.

The purpose has been to investigate leisure-time centers actual work on children with attention deficit disorder. In addition, the study strives to make leisure-time centers way of working, in relation to their assignments, visible. The study has also compared how the leisure-time centers work and what the research says. The survey was conducted with the help of three exploratory interviews with pedagogues and three-piece observations at the leisure-time centers. It was carried out at three different schools in two counties in Sweden.The results of the survey show that the schools are trying to create clear procedures, though the centers succeed with this in varied degrees.

The purpose of the thesis has been to explore the use of hedge fund styles when constructing portfolios of hedge funds (i.e. funds of hedge funds). The central question is if the use of hedge fund styles can significantly explain and improve risk adjusted returns (characterized by Sharpe ratios). The study has been done in collaboration with Optimized Portfolio Management AB who desire further knowledge and evaluation of hedge fund styles for their fund of hedge funds.To be able to create successful ex ante portfolios we have explored various prediction models for both risk and return. Our findings indicate that return prediction is problematic using simple models such as regression since the risk exposure of the indices appear to change significantly over time.

In order to avoid harmful substances ending up at the municipal sewage treatment plants, it is important to purify the wastewater at the source. One such source is the wheel washers available in many tire garages which are used to wash the wheels on our vehicles when we change between summer and winter tires. It is important to wash the wheels before storage, to extend the tires lifetime. The purpose of this study is to find a green innovative solution for reduction of emissions of heavy metals at the source, so that the sludge from the sewage treatment plants can be used as fertilizer. The target is to find a wheel wash method which leads to compliance with the guidelines for car washers, and that also provides a better washing result than with the existing method.

This paper describes Tempus Custode, a smartphone application with which the user may register working hours and travel time during the work day. The application communicates with a database via a server. The data stored in the database may be manipulated using an administrator tool, mainly for the composition of time reports. In this way, the user?s task of time reporting his day is greatly simplified.The application is able to automatically discriminate between work time and travel time, as it continuously fetches positioning data from the smartphone GPS receiver.

2013. The brave new time.We constantly look forward in time. There is a need today to constantly renew, replace and update almost everything in our lives. Although often stressful, these continual changes and upgrades can open up new possibilities and even be seen as enjoyable and stimulating.Values, opinions, and everything we create, is based on an experience of the past and predictions of what the future might be. I want to take advantage of these thoughts and find out how they relate to our exchangeable culture.

Stump harvest could be found in the late 1970?s and the early 1980?s. And now when the prices on energy are high it has become an interesting topic again. This work has been conducted within Holmen Skog?s stump harvest testing in Norrköping.

The fertility of dairy cows is of great importance in order to maintain high production. The decline in fertility of dairy cows the latest decades can have several explanations. The large emphasis on high yielding cows and the negative genetic correlation between milk production and fertility traits could be one of the main factors for impaired fertility. To find heats and inseminate the cow at the right time is crucial to receive high conception rate. Delaval has, in corporation with FOSS, developed Herd Navigator which is a management program that measure four biological parameters in the milk; progesterone, betahydroxybutyrate, lactate dehydrogenase and urea.

Every municipality in Sweden is responsible for offering its citizens adequate childcare. Parents hand in a preliminary schedule to the preschool for when their child needs to be in childcare, and based on this the preschool staff is scheduled. Some municipalities measure the actual time a child is in childcare. The essay idea comes from when I heard that one municipality was thinking of register the children's actual time in preschools. I started thinking on how to solve such a task.

One of the most serious and economically important defects caused by clostridia in milk products is the late blowing of semi-hard cheeses.Clostridia occur naturally in soil and can contaminate milk through crops contaminated by dung and soil followed by a less successful silage process, that give them opportunity to grow unaerobically. When anaerobic conditions occur, such as storage of semi-hard cheese, they ferment lactic acid to butyric acid and the gases CO2 and H2.At the fusion of Arla and MD Foods, a series of changes were conducted on the MPN method for lactic acid fermentation for clostridia in milk. These changes resulted in an increased accuracy due to an increased number of test tubes and the change of media from MRCM to BBB, Bryant & Burkey Broth, that was thought to be more selective for Cl. tyrobutyricum, the organism mostly found in hard cheese. When the number of dairy farmers that were given quality reduction fines increased, the new method was suspected and a validation was conducted.The validation included inoculation of different clostridia and bacillus strains into BBB substrate and enzymatic testing of positive samples with Rapid ID 32A.

This thesis was done after a request from the county?s administrative board of Västmanland to provide the board with a better understanding of how green areas have changed within Västerås municipality over time.The purpose and goal of this study was thus to measure and analyze how much of the green areas within Västerås municipality that have disappeared during the past one hundred years as well as to provide a review of previous studies regarding the importance of green areas for humans as well as the biological diversity.In order to answer these questions I have in this study used a combination of a literature study, cartographic analysis as well as a time series analysis. The computer software used to do the measurements of the green areas was ArcGIS which is a geographical information system.In the cartographic and times series anlaysis measurements and analysis was made of the district map of 1911, the economic map of 1950 and the property map of 2011. The measurements show that the municipality has grown with 46,3 km2 over the last one hundred years. New neighborhoods? have emerged and the municipality has expanded.

Propofol is an intravenously administered, hypnotic and short- acting pharmaceutical. One common sideeffect (>1:10) and therefore a disadvantage with propofol is the local pain that arise when the initial injection is given. Why the pain arise is not clearly understood. A majority of different pharmacological treatments, different doses and combinations, alternative administrations methods and physical interventions have been tried to reduce the pain when injection of propofol is given. One important task for the nurse is to relieve pain for patients.

Abstract Background Todays guidelines for advanced CPR emphasize chest compressions with good quality and early defibrillation. Prehospital CPR performed by ambulance crew, an automated external defibrillator (AED) is used. The AED analyzes the heart rhythm and the performer is following the advice to chock the heart or not, given by the AED. During on-going CPR there are sequences when no chest compression is performed known as hands-off time. Hands-off time includes the time for the AED to analyze the heart rhythm and the time when advice is given to the crew.

The aim of this study was to in laboratory experiments investigate how addition of urea, ECOX and structural materials can optimize sanitization during composting of sewage sludge. Today we strive for a sustainable society and the importance of closing the nutrient loop increases. It has therefore become even more important to safely reuse plant nutrients from human excreta to agricultural land. Partly because it increases the sustainability of society as the world's supply of many nutrients are finite, partly because it promotes human health, both by reducing disease transmission and by increasing Agricultural production. An untapped resource such as sewage sludge that is rich in nutrients and humus-forming materials could replace parts of the commercial fertilizers used in Sweden today. owever, sewage sludge contains undesirable substances such as heavy metals and drug residues, and pathogenic microorganisms.
