In this report I summarize the thesis, which is about to check what will happen if you decide to increase the interval between the a-checks, carried out on the Norwegian airline Widerøe. They want to know if an increase in time between the checks can give them an opportunity of increasing their aircraft fleet. In the current situation Widerøe has 11  Dash 8 Q400 and can consider a possible increase of 3 planes. This would be done without the need to increase accessibility of the hangars and increase in staff.What determines how often a check is performed is the maintenance tasks which has the shortest maintenance interval. On the Dash 8 the shortest interval is 600 flight hours.

Megalaria grossa is classified as Near treatened on the Swedish Red List. It is also a so called signals spieces, e. g. a spieces that function as an indicator, signalling a forest that is worthy of protection. The aim of this study was to clarify the status at selected localities in the province of Uppland and Gotland.

In the informational age of today, continuous learning is of greatest importance. The demand for this seems to be increasing, while at the same time people are under more pressure to carry out more tasks in shorter amounts of time. A way to solve the problem of finding time to learn could be to make use of the possibilities that Internet offers for learning at a distance. The purpose of this thesis is to, from a pedagogical perspective, contribute to the discussion concerning Internet based distance education for a target population consisting of professionals. We have found that some of the courses included in the two certification programs which we have investigated are suitable for Internet based distance education.

Jag förutsätter att den mänskliga populationen kommer att minska på mycket lång sikt, något som många populationsekonomer håller med om. De största hoten mot ekonomisk tillväxt vid minskad population finner jag vara de demografiska förändringarna och färre teknologiska innovationer. Genom att granska de endogena tillväxtmodellerna och empiriska undersökningar kommer jag fram till att det med största sannolikhet kommer att ske en ekonomisk tillväxt vid en minskad population. Detta kommer att ske genom teknologisk utveckling, ackumulation av kapital och framförallt genom ackumulation av humankapital..

A secondary and a pioneer tree species can with advantage be included in a mixed stand to increase the use of sunlight. Nitrogen-fixing plants have been shown to increase the supply of nitrogen in the soil by, for example, litter fall. This deposition acts as a biological fertilization, which may be used by non-fixing plants. Alder is a nitrogen-fixing, pioneer tree species that loses its nitrogen-rich leaves late in the autumn. The aim of this study was to examine the effect on the total volume of production, when different proportions of nitrogen-fixing Alder were part of spruce stands.

The aim of this study was to evaluate whether gallop training, rather than regular drive training, is worthwhile for trotters race performance. Another aim of the study was to expand the author?s riding- and driving capacity, and get more practical experience on the impact of interval training on trotters. The sample population in the study was two trotters, one Standardbred, and one cold-blood. Given the small sample population, the results of the study is only indicative on the effects of gallop training on trotters, and not conclusive.

The background of this study is an article in the hunting magazine ?Svensk Jakt? where Karl Hedin claims that his sawmills has not noticed any significant moose damages in the timber. The purpose with the study is to find out the causes to the moose explosion and what it has led to in today?s forests. A questionnaire has been sent out to sawmills in the region Dalarna with the purpose of finding out if sawmills receive moose-damaged timber and what they think about how they foresee future development. There were two causes of the moose explosion, that had effects on the moose population. The first cause was that the moose hunters wanted to raise the moose population, and by raising the calf shooting and by saving the cows they succeeded. The second cause was changing methods in Swedish forestry.

Uppsala like many other Swedish cities is affected by heavy housing shortage, in terms of too few existing flats and residents within the city limits. Every semester thousands of new students are facing the same problems of finding themselves adequate accommodation. The waiting lists for flats and student-dorms are getting longer for each year, and the situation is just getting worse. Simultaneously, Uppsala?s ambition is to increase its population and expand as a Swedish metropolitan, according to the Swedish governmental environment goals. This paper investigates and analyses the possibilities of expanding a city?s population by building high-rise buildings.

Along with other European farmland birds, the skylark (Alauda arvensis) has declined rapidly since the 1970?s. Between 1975 and 2003, the Swedish population of skylarks declined with 64 %. In Britain, the decline is often explained by alterations in farming practices in general and the shift from spring-sown to winter-sown cereals in particular. The dense vegetation structure of winter cereals is limiting the number of breeding attempts possible, causing the entire population to decline.

In an effort to evaluate the effects of restorations of float ways on population density of stream dwelling fish in relation to the changes in habitat, I studied the physical habitat restored and channalized sites and their population density of brown trout (Salmo trutta L.) in three streams in the municipality of Sorsele. The differences between the channalized and the restored sites where most noticeable regarding substrate which where generally coarser in the restored sites. The analyses showed that the proportion of habitat that where suitable to the age class 0+ where significantly lower in the restored sites compared to the channalized sites. Regarding age class ?2+, no statistical differences in habitat quality were found.

The river Bivaröd is one of the river Helgeån tributaries which has the highest and the fastest increase in water colour. The reason behind this increase is unclear but several factors have been suggested to affect this pattern. In this work, I studied the role of land use, iron and precipitation for water colour increase in river Bivaröd for the period 1976 -2011. Data from a field study along with data from SRK for river Helgeån were used for the analyses. The results showed that both water colour and iron concentration increase and that there is a strong correlation between these two variables.

This work is about collaboration and staining in the upper secondary school Electrical program. How should the coloring go to in order to increase students' motivation and thus facilitate students' learning is the main subject with the work. The study has shown that there is a functional co-operation today, and that students believe that if the cooperation would increase. It would also in-crease their motivation to improve..

This thesis deals with the concept of how price affects demand for a good by estimating various price elasticities of demand for snu sold in Sweden. Information was gathered on price development for snus and cigarettes as well as sales data from Swedish Match, the largest supplier of snus in Sweden. Income-, price- and cross-price elasticities were estimated based on log-log regression. Results show that snus is an inelastic good since the coefficient for price of snus was -0.536. This proved that a 1% increase in price causes a 0.536% decrease in quantity demanded.

With a starting point in the legislation for organic production set up by the Swedishcertification organization KRAV, the reasons to why these regulations are important isexplained and how pigs are affected by these rules. The study also shows how well the pigscope in the organic environment considering the origin of the genetic material; from theconventional pig population. The conclusion is that pigs do function fairly well in the organicproduction environment and the traits affecting their functionality involve: motheringabilities, strong legs, good meat quality, good sow durability and longevity, capacity to eatmuch roughage and dark skin color. There are however still many ways of improving theorganic population of pigs to make them more adjusted to the organic environment; forexample different traits brought into the breeding goals and the choice of good parent animals..

AbstractKnowledge is today usually used as a way to compete in todays working life. It has become a fashionable concept and is used without a purpose. Both Plato and Aristotle used knowledge as a concept and Plato foremost acknowledged the theoretical aspect of knowledge and called it episteme. The practical aspect of knowledge was by Aristotle called techne. Today there are several concepts that describe the practical and theoretical aspect of knowledge.
