Rotorsaksanalyser av testriggar : En studie av vad som krävs av Scanias forsknings- och utvecklingsavdelning för att rotorsaksanalyser ska fungera på bästa sätt
När Scanias maskiner som ska testa nya lastbilskomponenter eller hela lastbilar, så kallade testriggar, inte fungerar som de ska så fanns det i dagsläget en uppfattning att problemen i vissa fall dels var återkommande och dels var svåranalyserade. På grund av detta ville Scania Tekniskt Centrum (STC) införa rotorsaksanalyser av när testriggar inte fungerade som de skulle. Denna studie har undersökt vad som i dagsläget behövde förändras och vad som möjliggjorde att rotorsaksanalyser av fallerande hos testriggarna skulle fungera så bra som möjligt.En nulägesanalys gjordes. Resultaten av denna visade på att fyra roller fanns som var involverade i att åtgärda fel hos testriggarna, nämligen de som äger riggarna, de som arbetar med underhåll av riggarna, de som utvecklar riggarna och de som är ansvariga för arbetsmiljön och säkerheten hos riggarna. En process map skapades för att visa hur dessa roller i dagsläget samverkade för att bygga testriggar och åtgärda fel hos dem.Resultaten av nulägesanalysen visade på att fyra övergripande faktorer påverkade huruvida rotorsaksanalyser skulle kunna genomföras.
Bakom Spegeln : En essä om tvivlet eller det goda beslutet i en filmproduktion
The essay depicts the opposite views of the director and an actor during the filming of a specific scene in a feature film. The actor feels that he is not being listened to. This leads to unforeseen consequences for the director, as the actor no longer wishes to take part in the marketing of the film prior to its opening night. Everything is seen from the director?s point of view, she is working in a film world dominated by men.Questions are being asked if the director?s instructions are clear enough or if the actor, fearing getting lost, is mixing up his own feelings with those of the character he is portraying? What happens to the collaboration and how does it affect the rest of the team and the completion of the production? The director is also the producer.

Vårvetesorters effektivitet i användningen av kväve under den huvudsakliga tillväxtperioden
Crop efficiency in utilizing available nutrients is an important factor in increasing produc-tivity and reducing the environmental impact of agriculture. Nitrogen is the nutrient that plants need in the largest quantity and wheat, along with maize and rice, is the world's most cultivated crop. In this work, the Nitrogen Use Efficiency, NUE, during the major growth period, HTP, of twelve different spring wheat varieties, were examined. The NUE was calculated as the product of uptake efficiency of nitrogen, UN, and the conversion effi-ciency of nitrogen to biomass, EN. The purpose of this work was to find if there are varietal differences in NUE and its components among the twelve varieties and to link a high NUE to specific characteristics of the varieties.
Hur människors begrepp om urbana platser relaterar till bedömning av platsernas estetik och mikroklimat
The objective of this study was to uncover what aspects of urban plazas and parks that are most important for users? evaluations of places? aesthetics and microclimate (the characteristic climate for a limited space). This was done by investigating people?s general ideas of plazas and parks (the prototypical concepts) and compare these with place users? descriptions of four specific places. Interviews with two groups (31 and 24 persons respectively) were carried out in order to collect this information.
The Sound of the Rain Needs no Translation : Synen på samhället och den moderna människan hos Alan Watts
In the 1940s, 50s and 60s the two youth movements of the beats and the hippies emerged in the United States. Disagreeing with the progressive positivism of the previous generations these youths were part of a counter culture that adhered to an ideal of living in the present.Alan Wilson Watts (1915?1973), most known for his popularization of eastern philosophy and religion in general and Zen-Buddhism in particular, became one of the most influential and well-read advocates of the new movements. Drawing upon eastern philosophy and religion as well as modern psychology, Watts challenged the western world view by rejecting the dualism of self and environment, arguing that man is one with God and nature and claiming that nothing exists but the present experience here and now.Based on Watts? view of man and reality, and in the context of the emerging youth movements, this study examines Watts? criticism of western culture and society as well as his view on happiness and the possibility of a better life for the individual living in the west.The study shows that, according to Watts, the root of the problem facing western society lies in man?s incapability of distinguishing concept from reality, preferring abstract ideas and symbols to the experience present in everyday life.

Gotländsk grönsaksodling : utvecklings- och tillväxtmöjligheter
A diet based on a bigger part of locally produced vegetables can contribute to decreasing
environmental impact and improved health. In Gotland horticulture has increased more than in Sweden in total during the last 15 years. To investigate possibilities for development of Gotland´s horticulture, the cultivation of potato, vegetables, fruits and berries was mapped through a questionnaire among growers. Interviews and a workshop with growers and reseller were conducted to investigate the interest and prerequisites for growing new crops. In total approximately 2340 hectares of potato, vegetables, fruits and berries were grown in Gotland in 2012.
Bäddodling av matpotatis :
This study investigated potato growing in beds as an alternative to conventional ridges.It was based on results from field trials on bed-grown potatoes carried out by Halland Rural Economy and Agricultural Society in 2007, studies of literature and interviews with farmers with experience of bed growing of potatoes.
Due to their shallow root system, potatoes are one of the most drought-sensitive crops. Potatoes are often grown on sandy soils with poor water-holding capacity. Factors such as total yield, tuber size distribution and quality defects are negatively affected when water becomes insufficient. Wide beds have a more flat top which leads to more uniform water infiltration. Further on, beds have lower soil surface area due to its shape, and therefore, retain water more efficient.
In the field trials, which were carried out at the Stjärnarp Estate near Halmstad, potatoes were grown in beds alongside a conventional ridge-grown crop.
Provtagning av trädkärnor för att bedöma föroreningsgraden av klorerade lösningsmedel i grundvatten
Chlorinated aliphatic hydrocarbons (CAH´s) were used widely within dry cleaning facilities and for metal degreasing until their toxicity was discovered. PCE is still used as dry cleaning liquid. Today CAH´s are found in soil environment at places where they have been used in the past. The CAH-concentration in trees growing on contaminated land has quite recently received attention as a cheap and effective way of assessing the extent of a CAH-contamination. The method has however, not been put into use in Sweden.The aim of the study has been to investigate whether the CAH-concentration in tree cores could be used to delineate the spread of CAH in a soil environment under Swedish conditions in different seasons.

Utvärdering av befintliga passivhus : En byggnadsfysikalisk bedömning och mätningar om temperatur, och fukt analys på ytterväggarna
Energy price are on the way up to a high level that will not diminish in the future make us to focus more on the sustainable development for a better solution of residential houses. Passive house or low energy housing are one of the solution to make residential more environment friendly, in same time it´s a financial security using less energy, and saving money. The last 10 years in Germany and all around Europe the concept of passive house been developed, and people aim to know more about these concept that leading the market more attractive for passive houses. A passive house is a well designed building highly insulated and air tight with mechanical ventilated system for the whole building envelope that minimizes the use of energy for heating [1].The housing company Mimer has chosen to invest in low energy consumption in every new housing project. These future plan projects are decided to use less than 75 kwh per square meter annually in purchased energy [2].This thesis is about new constructed passive houses, and focuses on the evaluations of the temperature, and moisture condition for attic, external walls and joist.
The effect of domestication on insect resistance in cotton : bioassays with the insect herbivores Spodoptera littoralis and Agriotes spp.
A plant's defensive ability against herbivore attack can be influenced by many different factors, one of them being domestication. During human selection to improve the yield of plants, the resistance against herbivore attack can have been lowered, due to a trade-off for use of resources between these traits in the plants.
In this thesis I investigated the effect of domestication on resistance against herbivorous insects in cotton plants. I used different varieties and species of wild and domesticated cotton in three different experiments. A feeding assay was conducted, the mortality, development
time and pupal weight of larvae of the Egyptian cotton leaf worm Spodoptera littoralis was studied. In a second experiment the preference of the root-feeding beetle Agriotes spp.
