This project investigated how elevation and vegetation type influences variation in plant litter phenolic content and protein precipitation capacity among and within common plant species for two different vegetation types, heath and meadow, in a subarctic ecosystem in the Abisko region of northern Sweden. As nutrient availability generally decreases with increasing elevation as a result of decreasing temperature, I hypothesised that phenolic content would increase with elevation and be higher on the heath than the meadow. To test this, the total phenolic content and protein precipitation capacity was estimated in leaf litter from 13 species in both heath and meadow vegetation across an elevational gradient ranging from 500 to 1000 meters above sea level (m.a.s.l.) in the study region. The results showed that elevation and vegetation type both had a strong impact on both variables. Total phenolic concentrations decreased with elevation for the meadow, and were greater for the heath than the meadow.

The purpose of this study was to examine how Swedish newspapers framed the campaign Earth Hour. Did media encourage their audience to join in and how did they create a sense of togetherness regarding the campaign?The theories connected to the study are media logic, media events, identity and the media, collective togetherness, symbolic interactionism and discourse. The method used was a qualitative discourse analysis. We analysed three Swedish newspapers: Aftonbladet, Barometern and Svenska Dagbladet.

The level of neonate mortality in a free ranging fallow deer (Dama dama) population at the Koberg estate in south western Sweden was investigated using radio-tracking techniques. During this study a total of 36 fawns (17 ?, 19 ?) were captured and marked with vhf or gps radio collars; 12 fawns in 2008 and 24 fawns in 2009. The neonate mortality calculated by the Kaplan-Meier method was 23.6 % and the mortality caused by predation was low, since only 1 of 8 non-surviving fawns died from predation by red fox (Vulpes vulpes). The spatial behavior of the fallow deer neonates were examined at two different levels i.e.

This thesis describes the work process and the results for the development of a newkind of ergonomic cleaning mop, ranging from basic concept to a virtually productionready digital prototype. The project was made in cooperation with, Ömer Altun, whowas also the project supervisor, and whose plan it is to launch this new product onthe market in a foreseeable future. The mop is meant to be used by both professionalcleaning staff and ordinary home users. What makes this product unique is that it hasa movable center piece that simplifies the cleaning under low furniture.The work began with the establishment of a product requirements specification andlater a study of similar products and existing functional models was conducted. Afterthese surveys the work began with refining the existing concepts in order to makethem more complete.

Med anledning av gremmeniellasvampens (gremmeniella abietina) utbredning i våra skogar i dag och konsekvenserna det för med sig, vill skogsvårdsorganisationen så snart som möjligt få fram en metod för att lokalisera angreppen och bedöma omfattningen av skadorna. I denna uppsats har jag därför undersökt vilka våglängdsband som är mest lämpade för att lokalisera gremmeniellan och vilka som är mest lämpade för att skilja skadorna från gallringar och utifrån det ge rekommendationer till skogsvårdsstyrelsen för deras fortsatta arbete. Resultaten blev att våglängdsband 3, 5 eller 7 från Landsat satellitens TM sensor är de band som ger bäst resultat för att skilja ut bestånd där förändring har skett från bestånd som visar sig vara oförändrade. Enforma använder skillnadsbilder från enstaka våglängdsband. En kombination av två eller flera våglängdsband, samt inkludering av data från ursprungsbilden skulle höja noggrannheten i den statistiska analysen något.

The purpose of this study is to examine the attitudes towards criminality among adolescent people. The main goal of this study is to find out, which risk factors are for criminal behavior among the youth. It?s also to understand if gender and ethnicity of the adolescent people plays any part in their attitudes towards criminality and risk factors for criminal behavior. The study has been carried out using a quantitative method for the data collection.

Transportation constitutes a large part of the forest industry's raw material costs. Transport also contributes a significant proportion of the carbon dioxide emissions. In order to reduce both the cost and environmental impact different types of decision support are required. These, in turn, require extensive information about the road network and correct information on road path selection and transport distances. In the development of national road data base for forestry (SNVDB) a road selection application has been included.

Idag ses ett ökat intresse för användandet av rörelseanalys inom olika sammanhang t.ex. övervakning, dataspel och diagnostisk undersökning av personers rörelsemönster med mera. Optisk rörelseanalys är den teknik som finns mest idag, men de systemen är dyra och saknar lämplig mjukvara för klinisk användning.En forskargrupp vid centrum för medicinsk teknik och strålningsfysik (CMTS) forskning och utvecklings avdelning (MT-FoU) vid Norrlands universitetssjukhus har sedan 2007 jobbat med en produktidé som bygger på att skapa ett nytt mobilt system för rörelseanalys som kan användas i medicinska undersökningar. Ett Arduino pro mini kort samt ett 9-axligt prototypkort som består av MPU-6000 och en magnetometer HMC5883L är anskaffat för att tillverka ett system i detta syfte.Syftet med projektet har varit att skapa ett verktyg som kan samla in rörelsemönster för att sedan presentera resultatet i ett diagram. Systemet skulle kunna samla in data från en sensor som inkluderar en 3D-accelerometer ett 3D-gyroskop och en 3D magnetometer för att därefter skicka det vidare till en dator där mätdata presenteras visuellt och sparas undan i en textfil.En viktig detalj att ta hänsyn till vid konstruktionen av det nya systemet var att konstruktionen gjordes med hjälp av billiga standardkomponenter och kretskort.

In the post-war era many European countries were recovering from the ravages of the bombings of the second world war destroying whole countries. Sweden being neutral was spared the destruction of war but instead we demolished almost as much housing all by ourselves. A social program was modeled to modernize the country and to drag the swedes out of poverty by building one million apartments in just ten years and demolishing the old, dilapidated working-class neighborhoods. The traumatic events of the demolition of large areas of both the central and the outskirts of most Swedish cities is still very much present in the collective memory of people today and the new modernistic districts are still paying the price of that, more than fifty years later. Today these modernistic districts are in need of repair, and they are often homes to groups alienated from society making their reputation even worse.

Children?s utterances have been studied in different languages; however, only a few studies refer to Swedish. The aim of the present study is to describe utterance types, subordinate clauses and utterance length for a group of three and four year old Swedish children without known functional impairments.The study included 29 children, 17 girls and 12 boys, in a larger city in the south-east of Sweden. The children, all native Swedish speakers, were aged 3;0 to 4;11. Sound recordings were made during a playing session with one of the authors in the children?s day care centers.The utterances were divided into the categories elliptical responses, incomplete and partly unintelligible utterances, imitative utterances and independent utterances.

The aim with this study was to investigate mortality in older respectively younger beech stands (Fagus sylvatica), the different types of dead wood in the forest and the availability of coarse woody debris (CWD). The research was carried out in previously managed and seminatural stands in Biskopstorp and Frodeparken, located north of Halinstad in Halland,Sweden. Data were collected from 22 stands with at least 50 % beech and with a minimum age of 5 1 years, ranging in size from 0,67 to 19,9 ha. A transect was placed in each stand, in which the diaineter on both dead and living trees with a minimum diameter of 50 mm was recorded. On seven to 13 dead trees, depending on the size of each stand, decomposition stage, primary and secondary cause of death, amount of fungi and the type of the dead wood was noted.

AbstractThe purpose of this study was to investigate students' perception of their grades in relation to the grading criteria in physical education. To investigate this used issues: how values and experience rating criteria? How do students their teachers' planning of lessons? How do students grading assessment in physical education and what they believe is important? The method used was a questionnaire with closed questions. The answers were given on a six-point scale, ranging from 1 = "not true" to 6 = "totally agree". In a qualitative analysis of the quantitative material.

The dissertation were performed on SP, Technical Institute of Sweden. The dissertation were carried out on the measurement technical department, this dissertation is a part of a bigger project, project ClampCal. One of SP?s returning assignments are flow-measurement. When flow-measurement is performed, the flow has to be stopped so that a meter can be installed in the pipes where measurement is going to take place. At every stop there is time delay in the flow which causes the customers to loose money. This is why SP wanted to find a better solution so that measurement can be done without any stops in the flow. Usage of a so-called Clamp-on meter was considered, but since the measurement uncertainty is too large it takes some investigation on the parts where the largest uncertainties occur and thus find a solution that can diminish the uncertainty as much as possible. The parts that were considered to have an opportunity to reduce measurement uncertainties were the fluid temperature, its characteristics and the pipe geometry and its characteristics. For the fluid temperature a Pt100-sensor with four different radii for various pipes was used.

The snow leopard (Panthera uncia) is an elusive felid, native to the mountains in central Asia. Basic knowledge about the snow leopards? ecology has long been lacking but is advancing with the help of the GPS-technology. GPS cluster analysis can provide insight in the diet and prey selection of elusive predators, such as the snow leopard. Acceleration data from GPS collars can be used to study animal behavior but the two have never been combined to gain more detailed information of the feeding behavior of large carnivores.
