The purpose on this study is to determine the extent of possible connections between tendencies to increased violent behavior and increased alcohol consumption among a total cohort of girls in the 9th grade compulsory school and 2nd grade upper secondary school in a Swedish county. In 2004 the Epidemiological Department carried out a health-status survey, using a self-report questionnaire, with students from both private and public schools in a specific county in Sweden. All respondents (N= ca 4000), attending all compulsory (at 9th grade) and upper secondary schools (second tier) on the survey date completed the questionnaire. For this particular study, 9 questions from the questionnaire, all concerning self-reported violent behavior and alcohol consumption habits were used either individually or combined in index variables. The result showed that while violence experience is low among these 4000 girls, it increased in relation to a corresponding increase in alcohol consumption.

This master thesis was conducted in order to investigate the effects of the browsing species Yeheb on animal tissues in Swedish landrace goats and to make a literature review in order to increase the knowledge of the importance of this plant for livestock production in Somalia. The evergreen Yeheb bush is a very important feeding source for grazing and browsing animals in Somalia during the dry period. Yeheb contains cordeauxiaquinone that stains the bones of the animals red/pink, which has been an increasing problem when exporting meat to foreign countries. In an experiment, two goats were fed dry and fresh leaves from the Yeheb bush for one and two months, respectively. The goats did not feed the intended amount of dry leaves, since the supply and palatability was not as high as estimated.

Following an increase in hostile foreign activity. The discussion regarding Sweden?s defense force´s ability to perform its task has come to a new heading. With the end of the cold war as a major revolution in matters of international security, a major overhaul has taken place to transform the static total defense plan of the nation to a less rigid operational system.Following an analysis of the budgets total amount from the governments of 2002 until 2015 it is clear that while the amount of resources has never directly been lowered, it has shrunk in relation to the countries total GDP. The possible futures for the defense of Sweden bring three possibilities forward in correlation three unique perspectives on military and political policy.Out of the three possibilities the focus on military strength as a political resource seems to be garnering the most support with the latest incursions made my foreign submersibles and the ever growing presence of 5th generation of warfare.

It is not easy to understand people?s fears since they are not always a logical reflection of the danger in certain situations. This study is an attempt to give a scientific view of the potential danger that certain animals in Sweden pose and compare this to Swedes? fear of these animals. A report shows that Swedes? have a certain amount of fear for being attacked by a wild animal in the forest and this fear has increased for certain animals over the last years.

The connection between fluorescence and color management still is a relatively unexplored area. Thefollowing composition analyses the theory that when printing on fluorescent ink jet paper using ICCprofilesa more yellow print will appear. In theory the ICC-profile compensate for blue light that fluorescefrom the paper with the complementary color, yellow. The human eye apprehands this fluorescentlight as white.When categorizing a number of ink jet qualities some tests to indicate change of color in the final printwere made. Five qualities were chosen for further analyses, each with different white point.

In this thesis a transport system is sought after thatif realised in the city of Uppsala could provide bothwell-being to all its inhabitants and sustainability,here jointly refered to as liveability. It is found thatthe car dominated transport system that is inoperation today provides two fundamental values,namely accessibility in both time and space, whichsets it apart from other transport solutions. Thesetwo values are of immense importance for theliveability in our modern world. On the other handthe car dominated system decreases the liveabilityof Uppsala in several different ways. Some of theseproblems, it is argued, could be solved within thecar system, through the adoption of moreenvironmentally friendly cars etc., but otherproblems are inherent in the car system and willremain no matter what changes are made.

Mechanical harvesting may result in timber damages leading to reduced saw log quality. The initiator of this study was VIDA ? a privately owned concern operating in the value-adding process industry of forest raw materials. The aim of this study was to examine the type and amount of damages on Alvestakubb caused by the harvester head during the cutting process. The aim was also to compare the damages caused by different types of feed rollers and to evaluate the effects of temperature on damage occurrence.

AbstractManagement is a field that started getting attention in the beginning of the 20th century by Frederick Taylor. His publication is called the Principles of Scientific Management and is based on the principles of using scientific methods to find the best way of conducting each operation within a production facility. Many of Taylor?s principles may appear obsolete today but the matter of an effective material flow is still highly current. Efficiency is the relationship between the input into an operation and its result.

The aim of this paper is to describe how to measure welfare effect of the deregulation and increased competition of the public transport by railway in Sweden. The paper also includes a numerical example of how to measure the welfare effect. In our study we use public data from SJ regaring quantity and ticket prices for the period 1996 - 2005. We have used equivalent variation, EV, as the method to measure the welfare effect. We demonstrate how to derive the equation to calculate EV by starting with a Marschallian demand function.

In times of increased flooding, enhanced by climate change, polluted stormwater poses an increased threat to the environment through contaminated water entering waterways. Bioretention utilizes natural processes in soil and vegetation to treat pollutants and combat this threat. Biochar produced through pyrolysis, has a high cation exchange capacity (CEC) and could therefore increase treatment in bioretention systems. This research applies a literature review, interview, and a model to explore the benefits and disadvantages of biochar in order to specify a soil-mix through an understanding of the production process and preferred application rate. High purification through CEC, increased water holding capacity, and carbon sequestration being the benefits discussed.

In this paper the rate of convergence, speed of execution and symplectic properties of the time-integrators Leap-Frog (LF2), fourth order Runge-Kutta(RK4) and Crank-Nicholson (CN2) have been studied. This was done by solving the one-dimensional model for a particle in a box (Dirichlet-conditions). The results show that RK4 is the fastest in achieving higher tolerances, while CN2 is the fastest in achieving lower tolerances. Fourth order corrections of LF (LF4)and CN (CN4) were also studied, though these showed no improvements overLF2 and CN2. All methods were shown to exhibit symplectic behavior..

The amount of mergers and acquisitions between international and Swedish actors increased due to the Swedish entry in the European Union. In many cases, conflicts between manage-ment and employees made visible the cultural differences between nations and organisations. As a result of these conflicts many companies experience difficulties in operating on the Swedish market and in some cases they have even been forced to leave it.The starting point of this study is analysing how the management at a foreign company in Sweden, that has undergone a merger, has been affected in the meeting with the Swedish business culture. The analyse has got three different perspectives as a base; management, market knowledge and culture.This study is accomplished on the basis of a deductive approach. It is a case study where the empirical foundation derives from five interviews.

The purpose with this report was to compare three commonly occurring methods for measuring plant available nitrogen in soils. The methods extraction, incubation and Plant root simulator (PRS) probe - an ion exchange membrane (Western Ag Innovations, Inc., Saskatoon, Canada) method were used and comparison between these methods were conducted. A full factorial experiment were set up in northern Finland with the treatments excluding herbivores, warming and fertilization to see how the inorganic nitrogen content in the soil was effected by the treatments. Soil cores were taken and from them a subsample was incubated for 18 days and thereafter analyzed for inorganic N in laboratory. PRS- probes were in the ground for 1 month.

Ro Rollytech AB är ett företag med visioner om ett nytt träningssystem för rullskidåkare, där åkaren ska kunna samla in data under träning/tävling och sedan få möjligheten att utvärdera denna efter passet. I ett samarbete mellan Luleå tekniska universitets avdelning för Industriell design och Institutionen för systemteknik fick Rollytech under våren 2006 chansen att påbörja arbetet med sin idé. Ett digitalt träningstillbehör skulle utvecklas utrustad med en touch screen för navigering och med teknik som skulle möjliggöra trådlös kommunikation mellan träningstillbehöret och en rullskida. Den rullskida som skulle användas var en ny del av Rollytechs sortiment: en skida i glasfiberkomposit som Rollytech samtidigt hade under utveckling i företagsorten Öjebyn. Arbetet med att ta fram tillbehörets skal skedde genom ett examensarbete av Alexandra Teterin och Erika Hedvall som avslutning på deras studier i Industriell design.
