Underdrainage is a costly investment but often a necessity to maintain rationalized plant cultivation, one can also see underdrainage as insurance to successful plant cultivation. Late ripening crops, low yield and difficult tillage cultivation are examples on an insufficient drainage. (Kvarnemo 1983) A drained field rise in land price and the scheme of the tiled drains is seen as a value item. The interest for underdrainage among the farmers follows with shifting economic situations within agriculture and has for long time been low. A big part of the Swedish tiled drainage systems is since 1930 and ahead. Many of these tiled drainage systems need to be replaced or complemented. The life length of one tiled drainage system varies with maintenance but can still remain in good function after 75 years with correct management.

Stureholm Manor and garden is a relatively young farming unit on clay soil in the north western part of Skåne, a province in Southern Sweden. Since the middle of the 19th century the landscape has been actively cultivated and has been transformed from oak forrest into farmingland of high efficiency. The industrial era during the 19th and 20th centuries meant new posssibilites for cultivation of these clay soils. With equipment like steam ploughs and the possibility to obtain fertilizers, the harvest increased considerably. This increased prosperity provided estate Stureholm with a beatuiful corps de logi, a manor. The trends prevailing in Europe around the turn of the century 1800-1900 against the growing industrialism, was turned into a artisan movement known as Arts and Craft. The Swedish followers idealized our Swedish history and they took the turn of a national romantic movement that later turned into neoclassicism.

Abstract:Perennials in public areas have during the latest decades been more and more popular. This group of plants has become a more accepted komponent when creating pleasant public places, and people begin to see the functional aspects. Perennials do also give a colour- and senceexperience in a more detailed way than can be achieved with only trees and shrubs. One of the ojects of this essay is to give more examples of motives for using perennials in urban areas.Having in mind the increasing use of perennials, you can expect a growing need for better understading of how to create successfull perennial plantings. In spite of the increasing interest it is hard to find any written information in this subject.

This thesis investigates the situation for comics in Swedish public libraries. The main questions is separated into two groups, the first dealing with the physical situation were we investigate placement, cataloguing and shelf arrangement. The second deals with the librarians attitudes towards comics and how they may affect their work. The base for this thesis is the idea that the comic medium may sometimes be treated different than the rest of the libraries collections. Because of this, a theoretical basis is developed which focus on different views on comics.

The Convention on Biological Diversity (CBD) promotes the Ecosystem Approach (EA). In this thesis it is analyzed how the EA approach could be applied to regional management of coastal areas in Sweden. The aim of this report is to compare management for preserving biodiversity on a landscape level in two regional coastal areas in Uppsala and Västra Götaland respectively. In Uppsala, one of the plans consists of a previous nature reserve and in Västra Götaland, a Regional landscape strategy has been established. The ecosystem approach is used as a theoretical framework in this thesis.

Unwanted vegetation on the land of electric transforming stations is a problem, in the sense that it contributes to higher fire risks and also constitutes an obstacle for people performing maintenance operations at the station. Such unwanted vegetation is controlled using herbicides and mechanical measures. Since the use of herbicides implies environmental hazards, there is a need to find alternative ways of fighting the unwanted vegetation. Investigation into suitable plants for ground cover, trials in the greenhouse, trials in the field, soil analyses and compilation of experiences from similar trials are parts of this work. The paper also contains analyses of possible environmental benefits and economical gains. There is also a final discussion of some proposals regarding alternative weed controlling methods.

This thesis examines the deregulation reform of the Swedish railroad industry, focusing on passenger transport between 1988 and 2005. The purpose of the thesis is to examine the effects from the deregulation reform on prices, market concentration and to determine whether SJ (the state owned incumbent) has been conducting strategic behaviour in order to prevent new entrants to the market. The chosen method consists of interviews with the MD at SJ between 1988 - 1998 Mr Karl-Erik Strand, the transportation researcher at SSE Mr Gunnar Alexandersson. Statistical sources and companies financial reports have also been used. The results that I have found were besides the fact that the market concentration is still significant high and the profitability among the operators low, is that the prices has increased more than CPI during the period but the competitive tendering has resulted in lower government subsidies after the deregulation.

This master?s degree project concerns the combination of a multi dwelling passive house with solar energy for the generation of electricity and domestic hot water (DHW). Different alternatives with either solar thermal systems or photovoltaic (PV) systems are compared with two reference alternatives producing DHW from electricity or district heating. The economical comparison uses a life cycle cost (LCC) perspective based on the present value of expenditures for investment, energy and annual operating and maintenance.The energy yields from the solar energy systems were calculated by hand and with simulation software. Calculation and dimensioning of PV systems were carried out with a software called PVSYST.

The aim was to study the factors that contributed to the prescription of physical activity on prescription (PaP) by the professions in primary healthcare. A qualitative method was used in the study. The sample consisted of six participants; two doctors, two physiotherapists and two district nurses in primary healthcare in Uppsala County. The data were collected with semi-structured interviews and were analyzed with a thematic approach. The results show a great variety in which type of patient that receive PaP, however people with lifestyle diseases such as diabetes, hypertension and obesity are often more represented.

This thesis is a product development project that was performed at Alfa Laval Tumba AB. In the past Alfa Laval have manufactured gas separators for engines where gas flows were cleaned from oil. A new business area for this kind of technology has shown to be the manufacturing industry where oil mist has to be separated from the vented air. Therefore a new and bigger design is needed to be able to handle the greater gas flows. A product like that would be a strong competitor on the market when the maintenance would be low in comparison to today?s equipment.During the project several concept suggestions were developed using customer interviews and research as input.

Obemannade system blir allt vanligare både på den militära och kommersiella marknaden. Unmanned Aerial Vehicle, i vardagsspråk benämnt som drönare, är ett flygplan som ombord saknar en mänsklig pilot. Då utbudet och efterfrågan av obemannade farkoster ökar måste tillverkarna lägga mer fokus på att kunna erbjuda hela system, vilket innebär att vid försäljning kan ett komplett system för obemannade farkoster erbjudas. Därför är behovet av tillbehör och kringutrustning idag lika viktigt som det obemannade flygplanet.Unmanned Systems Group grundades 2012 med verksamhet i både Schweiz och Sverige. Företaget förser den globala marknaden med innovativa produkter och tekniska lösningar inom området för Remotely Piloted Aircraft Systems.

The purposeof this study was to investigate whether preschool staff who participated in a previous health project retains the good behavior change, and to explore their perceived barriers and opportunities for this. The study was conducted on a "feel good" preschool and the selected population was preschool teachers and/or child minders. The selected method was qualitative, descriptive, and through the interviews the respondents got questions about their behavior changes and their experiences of this. The result of the survey showed that nearly all of the participants in the study had maintained the good behavior changes and most of them had implemented them in their lives. The obstacles that individuals perceived were mainly time constraints and the opportunities they saw were planning, motivation and positive experience.

Implementeringen av tablets ämnade för inspektioner inom drift och underhåll av vägar har studerats och utvärderats med målet att fördjupa kunskaperna inom drift- och underhållsbranschen och skapa effektivare arbetsmetoder som gynnar alla byggprocessens parter.  Examensarbetet är utfört hos Peab på deras anläggningskontor i Sundsvall och implementeringen har ägt rum på deras driftområde Sundsvall som består av cirka 122 mil statlig väg där Trafikverket är beställare. Genom litteraturstudier, tester av tableten och deltagande observationer så har tabletens användbarhet och utvecklingspotential analyserats och slutsatser har dragits för att ge Peab feedback på deras innovation med ett antal förbättringsförslag. Utvärderingen blev ej fullständig då Peab inte hann införa tabletsen inom vägdriften innan de 10 veckorna för examensarbetet var avslutade. Att använda tabletsen inom vägdriften kommer att effektivisera inspektionerna med dels digital dokumenthantering och det viktiga införande av GPS positionering  i de fordon som utför inspektionerna. Detta kommer bli mycket smidigare än den tidigare arbetsmetodiken där i stort sett alla processer innefattande mycket onödigt pappersarbete. Peab rekommenderas fortsätta att se utvecklingsmöjligheter med tabletsen inom andra områden av vägdriften samt fullfölja utvecklingen av tableten för att få en användbar produkt. .

Husqvarna is a world leading producer of chainsaws with a well-established brand name. Husqvarna now has an interest in investigating the possibiltiy to expand their production of chains and guide bars to include cutting equipment for timber-harvesters.This project is a technical study which aims to answer questions about cutting equipment for timber-harvesters that have been decided in cooperation with Husqvarna. The questions have mainly been focused on forces, cutting speeds, service and maintenance -as well as general questions regarding the size of the Swedish market.Two methods have been applied to answer the questions. Interviews with retailers of harvesters, producers of harvester heads and harvester drivers.The main findings in this project show that there is a relatively small selection of harvester chains on the Swedish market. In contrast to the selection of harvester chains the selection of guide bars is quite large.

This study examines university employees? perception of their employment situation and career opportunities. By tradition, fixed term contracts are used in the Swedish research community due to dependency on insecure funding. There is a current debate that questions this use of insecure employments. The employments are said to negatively affect the university?s societal role and international competitiveness.
