Validation of Steins/Arla Foods method for lactate fermenting clostridia in milk
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.
Klimathotet i din tidning : En studie av klimathotets framställning i dagspress och kvällspress
The purpose of this study was to examine the threats from climate change coverage in the media. The climate threats start to appear more frequently in the media and because of that it is important to examine what the media conveys to the viewers and readers since it may effect how people act when it comes to climate threats.

Lämpliga områden för vindkraftsetablering på land i Norrbottens län
Wind power is becoming an increasingly important source of energy. There are several national and international goals set to increase to amount of renewable energy, and in order to meet these goals, the wind power production plays an important part and the establishment of new wind power farms are required. The Swedish national project Riksintresse Vindbruk has appointed areas in Sweden suitable for wind power, mainly when looking at the physical wind conditions of the area. In this study, I aim to define suitable areas for wind power establishment in Norrbottens län. In order to reach this goal, a critical regional method was developed and completed using GIS.

Den informella högskolereformen? : En explorativ fallstudie om högskolereformers påverkan på anställda inom högskolesektorn
This is a case study that explores the ways in which implemented university reforms have affected employees in the higher educational sector. Previous research within the research field has mainly focused on policy related consequences of the reforms. This is why a study that brings attention to the ways the reforms have affected employees is sorely needed.The aim with the study is to examine whether there is a discrepancy between formal changes and the ways the employees experience them. The study is based on interviews with 8 lecturers from two universities and the material is analyzed mainly through sociological neo-institutional theories, such as Richard Scott?s theory of the three pillars within an informal institution and Helmke and Levintskys theory of the relationship between formal and informal institutions.The results show that there is a discrepancy between the formal changes and the ways employees perceive them.
Utvärdering och uppdatering av typkurvor
The purpose of this thesis is to evaluate and update load curves for Fortum Distribution AB. Theload curve method is a tool used to forecast the strain of an electric grid. The method is based oncustomer annual energy consumption, outdoors temperature as well as customer category. Theload curve method was established by Svenska Elverksföreningen at the start of the nineties andfocus was put on standardizing annual energyconsumption, in order to make the method usableacross the nation. Present consumption patterns have changed since the original load curves wereproduced, which leads to a need to update the load curves.The work began with an update of present load curves according to recommendation taken fromanother earlier thesis.

Indoor Positioning Using WLAN
This report evaluates various methods that can be used to position a smartphone running the Android platform, without the use of any special hardware or infrastructure and in conditions where GPS is unavailable or unreliable; such as indoors. Furthermore, it covers the implementation of such a system with the use of a deterministic fingerprinting method that is reasonably device independent, a method which involves measuring a series of reference points, called fingerprints, in an area and using those to locate the user.The project was carried on behalf of Sigma, a Swedish software consulting company..
Att spegla verkligheten - en studie av simuleringar i geografiundervisning på gymnasienivå
I arbetet görs ett försök att genom litteratur och elevintervjuer närma sig frågan om vilka förutsättningar för lärande som simuleringar i geografi erbjuder och vilka lärandeteorier som då blir relevanta. Intervjuer har därför gjorts med elever efter att de genomfört ett för undersökningen utvalt simuleringsspel. I arbetet ställs också frågan om hur elever uppfattar simuleringen som didaktiskt verktyg och ett antal svarskategorier struktureras. Slutsatserna är att lärandet i simuleringar i första hand tycks vara beroende av den egna praktiska erfarenheten, den sociala interaktionen mellan deltagarna och den emotionella laddningen. Elevernas uppfattningar av lärandeformen stödjer dessa kvalitéer, men tillfogade också betydelsen av variation i undervisningen och det inneboende spelrummets betydelse för kreativiteten..

Pedagogers adaption av surfplattor : En studie av implementeringen av iPad i en F-5 skola
The tablet is a new IT-tool which have started to get introduced into school, but research is still missing and especially in the pre-school environment. The purpose with this study is to investigate teachers uptake, how they use the tablet in everyday pedagogy work as well as the organizational conditions that that facilitate and hinders. Through my observations and interviews in a Swedish K-5 school I have found that the teachers find tablets more appealing to use in comparison to computers. These findings are partly supported by Davis et al.?s (1989) TAM-theory who considers there to be three types of aspects that affect the way individuals adapt to technology.
Upprustningsmetoder för en bankropp : En jämförelse ur ett LCC-perspektiv
In recent years, the Swedish railway track system has been neglected in terms of capacity and maintenance. To adapt the existing system to current traffic load there is a great need for extensive improvement and maintenance. Shortcomings are especially occurring on older embankments running over soft subgrades. To select the most suitable method for reinforcement of the embankment, it is important to evaluate different solutions from a life cycle cost perspective. In long-term perspective, it is often shown that a method with low investment cost causes a higher maintenance cost and a shorter technical lifetime.
Preparera prepositioner - Sång och musik som didaktiskt hjälpmedel för prepositionskunskap i spanska
Abstract
A central problem in all language teaching is to teach the correct use of prepositions. There are grammar rules, but also a lot of exceptions and idiomatic expressions that often have to be learnt by examples or by heart. A trick for learning might be to use a mnemonic method with songs and music to memorize a correct use of prepositions.
The purpose of this study is to test a language teaching didactic exercise for knowledge of preposition in Spanish with songs and music. Grammatical aspects, rules and exceptions when studying prepositions in Spanish are presented.
