This study evaluates the retention of nitrogen and phosphorus in four newly constructed wetlands in the municipality of Falkenberg, Sweden. The four wetlands have been selected because they have been specifically constructed with the aim to reduce nitrogen and phosphorus in farming areas. The process of selecting the specific wetlands has been done in collaboration with the county administration in Halland. Through field studies in collaboration with the landowners where the wetlands are sited, the areas that provide the wetlands with water were determined. The size of these drainage areas were determined in a GIS computer program. The type of land use within the drainage areas was also determined.

I dagens företagsklimat krävs det att medelstora tillverkande företag tillverkar produkter med hög kvalitet, för att vara i framkant vad gällande ledande kunskaper inom företagets verksamhetsområde. Ett sätt för företag att ständigt utvecklas och driva en vinstdrivande verksamhet är att fokusera på kvalitetsarbetet. Total Quality Management (TQM) är ett kvalitetsarbetssätt som utgår från företagets kunder, som likaså skapar förväntningar på företagets produkter. För företagsledningen innebär detta att förstå kundens förväntningar, tolka förväntningarna och förmedla dem till resten utav verksamheten. Företagsledningens ansvar är att organisera produktionsprocessen på ett vis som möjliggör ökad kontroll av kvaliteten och samtidigt bidrar med kvalitetssäkrad information för resten av verksamheten, medarbetarna.

Valet av ansats är viktigt för att kunna avgöra lämplig analysmetod. Det finns sedan två sätt att mäta hur verkligheten ser ut och det är genom induktion och deduktion.

During recent years the use of TMR (total mixed rations) has increased in Swedish lamb production. For many years TMR has been used for cattle and hence the information and knowledge is vast, while the knowledge concerning sheep and TMR is more limited. The aim of this thesis is to present an overview of the scientific knowledge on the subject, and also to compile practical experience from sheep farmers using TMR. The thesis begins with a literature review where different aspects relevant to the usage of TMR are dealt with. It is concluded that there are differences between sheep and cattle that must be taken into account.

Vid operation av primär total höftplastik finns det olika metoder för postoperativ smärtlindring. En tidigare genomförd studie på ett mellansvenskt sjukhus (nedan kallad ?höftprojektet?) visade att ?Local infiltration analgesia? (LIA) initialt minskade postoperativ smärta, underlättade mobilisering samt förkortade vårdtiden, jämfört med spinalt morfin. I denna studie genomfördes en långtidsuppföljning av höftprojektet med mätningar efter 6 respektive 12 veckor. Studiegruppen hade fått LIA vid operationsslutet och kontrollgruppen spinalt morfin.

The wild boar Sus scrofa population in Sweden has increased rapidly in the last decades which has led to conflicts among stakeholders, for example due to crop damages in agriculture. Thus, there is an urgent need of quantified goals and effective strategies for wild boar management. To develop such strategies, knowledge on population dynamics is fundamental. In this study a deterministic matrix model was used to estimate population growth, based on previously published data. The exponential growth rate for a wild boar population was calculated to 1.48.

Nutrient enrichment is the main cause of the increasing eutrophication process in the Baltic Sea during last century. A prerequisite counteract this process the load of nutrients to the Sea must be investigated. The large contribution of nutrients to the Sea is caused by emission from the rivers within the drainage basin. For the total emission of nutrient into the Sea the retention process in the rivers has big influence. This process in the river system has been assumed as a not important part of the nutrient cycle.

The low bearing capacity of roads during the spring thaw and periods in the autumn leads every year to increases costs for Holmen Skog. To reduce costs and increase accessibility Holmen Skog decided to install and test a CTI-system. Central tire inflation (CTI) is a system that makes it possible to monitor and vary a vehicle?s tire inflation pressures from the cabin, while the vehicle is in motion. When tire pressures are reduced, the area of the contact surface between the tire and the road increases, thus reducing the ground pressure. The purpose of this study was to evaluate the CTI-equipped vehicle and analyze if the CTI technology is economical defensible during the thaw 2005.

The incineration of waste is steadily increasing in Sweden and so is the production of ashes. The bottom ash has for many years been used as construction material in landfills. Now many of the nation's landfills are closed and there is a great need to find another beneficial use for the ash. Bottom ash is a gravel-like material and with its material properties it can replace natural gravel in parts of roads and surface constructions. Today this use is only approved within landfill areas where leachate is collected and checked.

Title AB Volvo Pentas packaging system ?process and packaging logisticsAuthor Peter Powell, Lund's Technical CollegeSupervisors Annika Olsson, Lund's Technical CollegeJan Svensson, AB Volvo PentaProblem - Packaging requirements ? Which requirements are there, how do they affect each other and how are they fulfilled?- Packaging process ? what is the line of action when developing new packaging and making adjustments in existing ones? Who has the responsibility to do what?- Packaging logistics ? How is the packaging system adapted to transport efficiency and handling?Objective To create an overall picture over how the packaging system affects and is affected by different functions and players within and beyond the company boundaries, to give a clear picture of how changes in the packaging system is made today and how it could work and finally to give suggestions for cost savings affected by the packaging system.Method The methods used for this thesis has mainly consisted of action research and at some extent case studies. As a previous employee at the department of logistics at Volvo Penta I?ve taken part of the environment, information and prerequisites that this thesis discusses on a daily basis. Case studies have been used for the collection and analysis of data concerning packaging logistics as I?ve chosen to consider only specific markets and packaging.Conclusions This thesis has highlighted the demands that are placed upon engine packaging throughout all concerned units and how these demands affect each other, positively and negatively.

This essay concerns the notion of how immigration politics, defined as a political discursive structure that explains and justifies how and why the movement of people into a state's territory is restricted and controlled, has come to present its purpose not as solidarity with the 'immigrants' wanting to enter the state but as a protective measure for the state's citizens. By using discourse theory combined with theories from the International Relations field I attempt to explain why and how such a discourse positions 'immigrants' as a threat to the state.First, I concentrate on why an immigration politics discourse would position 'immigrants' as a threat. I argue that in order for people to construct their identity, the 'outside' what they "are not" has to be repressed. In the same way, the state has to dislocate the "outside" and create threats to uphold its supremacy. These boundaries are set to create a feeling of predictability and security, and ultimately they are a way of making peoples' "world" coherent.

In relation with structure transformation in farm companies with bigger animal population and pressure at the milk price, the farmers in both countries have to invest more money in the company to endure. This had conduct what more owners had seen grown requirements to invest in bigger population barns. The investment is necessary to retain stability in the economy for the companies, at that time when the profitability for small production barns decrease. This essay carries out through a case, there the activities main part are milk production. The present operation consists of 82 milk cows in long stall with a yield on 10 500 kg ECM. The idea is that the company should increase the activity to 180 cows.

Sibirisk lärk (Larix sibirica och Larix sukaczewii) är ett snabbväxande barrträd som odlats i Sverige i mer än 100 år. Trots det finns det få studier angående dess potential i Sverige och dessutom visar studierna på skilda resultat. Med data från bestånden med sibirisk lärk i Siljansfors försökspark, har höjdutveckling och tillväxt studerats. Med detta kandidatarbete avsågs att fastställa sambandet mellan medelhöjd och beståndets totala volym, ta reda på om den sibiriska lärken slutar växa på höjden vid 80 års ålder samt ta reda på när den årliga löpande tillväxten sjunker under den årliga medeltillväxten. Totalt ingick elva avdelningar med sibirisk lärk, som var mellan 48-94 år, i studien. Genom regressionsanalyser har samband mellan aktuella variabler skapats och analyserats. Resultatet gav att sambandet mellan medelhöjd (m) och total beståndsvolym (m3sk/ha) följer regressionsekvationen: Total beståndsvolym = - 73,3 + 13,1 medelhöjd + 0,386 medelhöjd2 Resultaten var att lärken inte slutar att växa på höjden vid 80 års ålder, snarare tycks höjdtillväxten inte avstanna förrän efter 90 år.

Due to recent legal enactments regarding carbon dioxide emissions, the car industry is facing higher demands. An effective way of reducing these emissions is to minimize the weight of the vehicle. This thesis constitutes a feasibility study on whether or not it is applicable for the car industry to utilize an inner floor structure comprising composite materials. The principal was the projectSåNätt, in which the main participant was Volvo Cars Corp. In consultation with a reference group, consisting of delegates from the industry and KTH, a specification of requirements was produced.
