Riskbedömning och riskhantering i samband med vägbyggen

The aim with this thesis is to investigate the risk management at the department Road construction, The National Road Administration Region Mälardalen. The aim is also to study how the risk management could be improved to better support the project leaders. Included in theses aims is to examine potential problems with the current risk management and to suggest changes. It is of utter importance to define the concept of risk, to study how risk can be measured and in which ways risk can be analyzed. In doing so, a literary study has be done and fourteen respondents has been interviewed.Risk is to be seen more as a concept than a quantity.

Measurement of ejection fraction of the left ventricular - A comparison between echocardiography and isotope angiography

Background: Documents and legislation inform us that parts of the public health service of Sweden, at a political level, aim to support people?s sexual health. Statistics show there has been an increase among young woman, seeking help for sexual pain during intercourse. The diagnosis that the media has come to observe lately is vulvar vestibulitis. In general there is a lack of knowledge about the existence of this state of pain and its causes, which impacts woman to get appropriate help and support in time.

Sjukvårdspersonals upplevelser av att använda bedömningsinstrument på barn (Pediatric Early Warning Score)

AbstractThe aim of the studie was to investigate if the Pediatric Early Warning Score system, PEWS, is an useful instrument on a children's inpatient ward, regarding the detecting of deterioration in children's vital signs. For this, a quantitative descriptive design with qualitative elements was used. Method: Study specific questionnaires were distributed to 86 persons (helpnurses, nurses and doctors). Of these, 36 answered and sent back the surveys. Results: Of 36 responses 25 felt experienced a faster detection of deterioration of vital signs in the child.

Det tysta samtyckets motstånd : En systematisk litteraturstudie över elevinflytande i skolan

School activities are under constant discussion. This literatur study examines student participation and its relationship to democracy mission and the factors that contribute to students marginalized in school. The study also intends to examine the relationship between intersektionall analysis and the limitation of opportunities for student participation in school. The study results problematize the relationship between student participation and school democracy quests, this by highlighting the challenges and difficulties the school faces. Our results also strengthen the relationship between the study theory and marginalization of students and the limitation of opportunities for student participation..

Peas as feed for dairy cows

AbstractAn approaching overproduction of cereals and a future uncertain supply of non genetic modified vegetable protein feedstuffs have increased the interest in an expansion of the domestic production of protein feedstuffs in Norway. Besides rapeseed (Brassica campestris), peas (Pisum sativum) may be the most suitable crop for this purpose. Peas are characterized by having a relatively high content of crude protein, ranging between 20-26%, a high content of starch, 42-51%, and a low content of fat. In general, the energy value for peas is higher than for barley but lower than for rapeseed and soybean meal.Pea protein consists of albumins and globulins to 85-100%, which leads to the fact that a large part of the pea protein is soluble and degradable in the rumen. Starch in peas is on the other hand to a large extent resistant to rumen degradation compared to starch from other starch rich feedstuffs.

Skjuvhållfasthet och deformationsegenskaper för Uppsalalera med CRS och standardödometer

Shear Strength and Deformation Characteristics of Uppsala Clay with CRS and Standard OedometerTyra Morell Bonin & Magdalena MählerTo see how much a clay compact under different pressure one can use several different methods and in this project, two methods were used, the Standard Oedometer and a CRS apparatus. A Standard Oedometer is a full-time manual device and the CRS apparatus is a modern electric and automatic device. The aim of the project was to see similarities and differences between the two methods and examine which method that were most reliable. This has been done with repeated laboratory tests and afterward evaluations. With this information one can get a picture of how the clay will behave and how it will deform in nature.

Occurence of mould and mycotoxins in  Swedish maize silage - a pilot study

During the last ten years the cultivation of maize in Sweden has increased and is expected to grow further. Most of the maize in Sweden becomes silage which is used to feed animals at farms. Maize has in other countries been shown to be a substrate for growth of mould and especially Aspergillus spp., Fusarium spp. and Pencillium spp. has been reported.

Evaluation of a new microarray method for genotyping of HLA-DQ2 and HLA-DQ8 for investigation of celiac disease

Celiac disease (CD) is an autoimmune disease, induced by an immune mediated reaction in the small intestine after ingestion of gluten and related prolamines. There is a strong genetic linkage and most important are the genes that encodes for HLA-DQ2 and HLA-DQ8. The European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) has developed new guidelines for investigation of CD in children and adolescents, which include genotyping for HLA-DQ2 and HLA-DQ8. Therefore, the clinical microbiological laboratory in Västmanland wants to introduce a method for analysis of these genes. Microarray is a newly developed method for determination of the alleles HLA-DQA1 and HLA-DQB1 that encodes for the ?- and ?-subunits of the HLA-molecules.

Undersökning av elkvalitet i distributionsnät med omfattande vindkraftselproduktion

The goal for this master thesis project has been to investigate the power quality in adistribution grid, which has a high fraction of dispersed power production due towindmills. The study has been done on a grid in Laholm South of Halmstad, whereapproximately 45 windmills are connected to the distribution grid owned by SHKEnergi. The investigation has been focused on to two radialy fed 20 kV lines, wheretwelve windmills are connected.Voltage variations have been studied by creating a model of the grid in the simulationprogram SIMPOW. The largest deviation that has been found in any point of the gridis ±1.9 % of the nominal voltage. This deviation is a result of varying powergeneration from the windmills and the voltage regulation at the connection point ofthe line.

"Hörre ni grabbar" : En studie om hur pedagoger bemöter pojkar och flickor i ordningsskapande siuationer.

Previous research studies have shown that teacher?s attitude towards girls and boys rather reinforces, than counteracts behavior as stereotyped gender concepts. Order and discipline seem to be important parts of the daily routines in school context and to maintain discipline a constant communication and dealing with pupils are in order. The purpose of our examination aims to study how teachers respond to boys and girls in situations like creation of order. The analysis is based on observations of the interaction that takes place verbally and none verbally between pupils and their teachers in creation of order situations.

Tidiga insatsers betydelse i lärmiljön : ? en studie av ett elevhälsoprojekt om lärmiljö från ett specialpedagogiskt perspektiv

Early intervention is important on different levels and must be justified as a social and economic long-term investment. There is no doubt about the importance of early detection when helping children/students in need of support. What kind of support that is deemed suitable and who provides the support can be viewed from different perspectives and with different approaches. Seen from a relational perspective the special education process is a long-term process and affects not only the individual but the whole school culture and systems may need changing. This study intends to describe the importance of the learning environment and what efforts are initiated early for students in need of support from the special education point of view.

FN:s Milleniemål och deras påverkan på den svenska biståndspolitiken

The purpose of this thesis is to study to what extent the UN millennium development goals have influenced Sweden?s development policy. The research method that I have used is a qualitative text analysis and I have studied the ideas in governmental texts and millennium development goals reports from 1995-2008.My hypothesis is that the basic ideas that has symbolized Sweden?s development policy has not changed much since the adoption of the millennium development goals in year 2000. This hypothesis is based on different ideas that the basic perspectives in international development policy are rather constant.My conclusion is that many of the areas that are affected by the millennium development goals already are prioritized areas within Swedish development policy, for example poverty reduction and gender equality.

Diagnos av stiktion i reglerventiler för prediktivt underhåll

This master thesis reviews advances in detection and diagnosis of static friction (stiction) in control valves. Control valves suffering from stiction results in oscillating control loops which in turn decreases both the process stability and reliability. Perstorp AB sees a necessity to automatically detect stiction in valves before the effects of the malfunctioning valves have become too severe. This thesis presents an introduction to maintenance, control loops and how stiction in valves can affect performance of control loops.A selection of methods presented in the literature are introduced and examined using normal operating data from the site in Perstorp. Common for all selected methods is their intuitive ideas and that they are based on normal operating data and minimum amount of process knowledge.

Hur fungerar en glaselektrod?

To understand the glass electrode needs knowledge from more than one level. The construction ofthe glass electrode is one part, an other is the composition and structure of glass. The Nernstequation have an important role, but also the sources of errors in the analysis and the calibration ofthe glass electrode. Focus for this article is how the glass electrode really works and how Gibbs freeenergy made the potential dependent of the concentration of H+and gives the logarithm to thefunction. Nikolskii's ion exchange theory starts to explain the question about how the potentialcreates and Baucke's dissociation mechanism made it more explicit.
