Grundvattensänkning till följd av järnvägstunnel genom Hallandsås : miljökonsekvenser relaterade till förändrad kväveomsättning i mark
This thesis was carried out to give some background information to a report of SLU (Swedish University of Agricultural Sciences) for the Swedish National Rail Administration (Banverket). The requested information was to provide basic data for an environmental impact assessment of the construction of the tunnel through Hallandsås. The aim with the thesis work was to discuss and quantify the leaching of nitrate and the emission of nitrous oxide from the soil at the groundwater level established through the tunnel project. The nitrogen related processes that could be affected were described and discussed. The different areas where a decreased groundwater level can cause changes in the nitrogen processes are the wet and moist areas.
Stadsplaneringsideal. Med den periurbana zonen i fokus - dess potential för den hållbara staden
To be able to plan for the expansion of a town, one needs a vision of the future appear-ance of the town. It is the current issues (social situation, Supply and demand, political control etc.) which decide what the ideal for town planning is. This is turn is the steering factor of the physical structure of the town. Therefore, the town's structure is decided by these ideals.In this report, I will present planning ideals that have historically been, and which criticisms that have been directed towards them. With reference to these issues, I will present those guidelines and ideals we have today for planning of our towns.
Threats and opportunities for the survival of the Yangtze finless porpoise
The Yangtze finless porpoise (Neophocaena phocaenoides asiaorientalis), is a small freshwater cetacean which has recently fallen dramatically in number. It is an endemic species for the Yangtze River and unless drastic action is taken, it risks the same fate as the now functionally extinct Yangtze river dolphin (Lipotes vexillifer). Threats to the porpoise are diverse but they have in common that they are caused by man. Development of the river has been made to Supply a growing human population with food, hydropower, and to reduce the risk of flooding. These changes have resulted in a degraded habitat for the porpoise.
Grundvattenmodellering i Badelundaåsen
Over an extended period of time there have been plans to establish a shared facility in Lennheden to extract groundwater from the Badelunda esker to provide drinking water for the cities of Borlänge and Falun. The city of Falun is dissatisfied with the quality of its drinking water and the city of Borlänge is concerned about the risk of contamination of its existing groundwater Supply at its current location. To provide a basis for a decision on this issue, the company Midvatten AB has been commissioned to perform hydrogeological investigations in the area of Lennheden.The purpose of this thesis is to design a functional groundwater model of the area between Lennheden, place of planned extraction, and Övre Tjärna, place of existing extraction, to get a better understanding of the groundwater situation in the area. A groundwater model enables simulations of different scenarios in risk assessment and contaminant transport. The aim of the thesis is that the model can be used as an aid in Midvatten?s investigations in Lennheden and that it also can be used in future projects in the area.The model has been made in Processing Modflow 5.3 and encompasses an area of 19,5 × 11 km along the Badelunda esker and the river Dalälven between Djurmo and Frostbrunnsdalen.
Centrumhandel i relation till externhandel : - en fallstudie om Strängnäs
In the 90's the establishment of external trade centers had a strong growth in Sweden, primarily in large and medium cities. Gradually took smaller towns by this development. In larger cities with larger and growing customer base than in small towns were not affected by the trade centers heavily, but in the smaller towns where the customer base was smaller, there was a risk that it created a negative competitive relationship between external trade center and trade in the citycenter. In some cases, competition is a positive development for both the citycenter and external trade areas, but in some cases there was a risk that the center became impoverished. In such situation there are theories that the different variety of different types of goods should be at the center and in external trade center could lead to a balanced trade relationship.
Improving peri-urban home gardens in Hyderabad, India
Insufficient intake of vegetables is a reason for micronutrient deficiencies and malnutrition in developing countries. With urbanization, globalization and a growing world population it is of major importance to secure sufficient food Supply for the world?s population. Part of the solution to increased food security among the world?s poor could be the introduction of vegetable home gardens, plots for small scale vegetable production which can provide households with sufficient vegetables as well as serve as an extra income source.
The study Improving peri-urban home gardens aims at examining the existence of vegetable home gardens in the peri-urban areas of Hyderabad, India.
Ombyggnation till passivhus
Energy issues are constantly increasing attention in today's society. People's impact on Earth isentered in more contexts. Many discussions are about how the entire social structure needs to bestreamlined in order to achieve sustainability. The residential and service sector accounts for 39 % oftoday's total energy consumption in Sweden and the increasing electricity prices have made buyersmore interested in energy issues.There are many buildings in need of refurbishment today, including all the apartments that werebuilt in the 1970s to reduce the housing shortage at the time. 650 000 apartments of one millionapartments were built during the so-called the one million program and is currently in need ofrefurbishment.
Gröngödslingens roll i odlingssystemet : en jämförelse mellan Mälarregionen och Östergötland
Green manuring is a way of creating an organic fertilizer by growing a crop that is mowed down. Besides the fertilizing effect this method has been shown to have a positive influ-ence on soil organic matter as well as weed flora, and green manure is an important me-thod of weed control in organic farming in parts of Sweden. However, the release of nu-trients from the green manure varies and can therefore be difficult to control. Risks for losses of nutrients are also present. Although the area of organic farmland is increasing in Sweden, the use of green manure is decreasing.This report contains a literature study which compiles research on the functions of green manure in a cropping system and also how the crop can be used if harvested, for example to produce biogas.
Investigation of power supplies used in OSC950
SammanfattningOCS950(Object Controller System 950) är en av Bombardiers produkter som hanterar säkerhetssystemet i järnvägstrafiken. Det består av olika delsystem och strömförsörjs mha nätaggregat (PSU ? Power Supply Unit). I den här rapporten undersöks den befintliga PSU74-modellen samt nya switchade nätaggregat som finns på marknaden.Bakgrunden till att Bombardier vill byta ut PSU74 mot ett nytt switchat aggregat är att PSU74 har en vikt på 14 kg och tar stor plats i el-skåp. Ett swichat nätaggregat väger ungefär 1,5 kg och är så pass kompakt att det tar litet utrymme i el-skåpet.Bombardier har medvetet väntat med att gå över till SMPS eftersom tillförlitlighet blir ett problem.
Analys av Husqvarna AB:s lastbilstransporter till Italien
The thesis has been written as a part of the Bachelor degree in Industrial engineering and management at the School of Engineering in Jönköping. The work is focused on the part of Husqvarna AB?s Supply chain that is associated with the lorry transports to Italy. Husqvarna AB has approximately ten Italian customers, whose delivery patterns have been studied from January 2007 to July 2008. Some of the customers have a low delivery frequency and small amounts of goods that they therefore have not been fully analyzed in this report.

These steps have been created to ensure the next generation?s energy demand. In EU and Sweden objectives have been set to ensure that the energy consumption decreases by 20% year 2020 and by 50% year 2050 compared with the energy consumption levels of year 1995.
Inköpsbeteende på byggarbetsplatsen: en studie av NCCs
projektinköp med ramavtal
Byggbranschen i Sverige idag lider av alltför höga byggkostnader. Kostnaden för byggmaterial stiger fortare än både lönehöjningarna och konsumentprisindex. Detta problem har NCC uppmärksammat och de har satt upp ett mål som går ut på att varje år fram till år 2012 sänka produktionskostnaderna med 5 %. En stor del av produktionskostnaderna är inköpsrelaterade och stora resurser läggs på besparingar i inköpsarbetet för att nå detta mål. Detta examensarbete fokuserar på inköpsarbetet på NCCs byggarbetsplatser och på hanteringen av tre av de största ramavtalen som NCC knutit med leverantörer av förnödenheter och byggmaterial: Ahlsell AB, Beijer Byggmaterial AB samt Ramirent AB.

Titel - Nyttan med RFID i IKEAs försörjningskedja - Ett sätt för IKEA att uppnå spårbarhet.Författare - Sven MorénJesper SamuelssonHandledare - Mats Johnsson, Universitetslektor vid institutionen för förpackningslogistik, Lunds Tekniska Högskola.Daniel Hellström, Doktorand vid institutionen för förpackningslogistik, Lunds Tekniska Högskola.Allan Dickner, Förpackningschef inom IKEA-koncernen.Nyckelord - Spårbarhet, Märkningssystem, RadioFrekvent IDentifikation, Information.Problembakgrund - Informationsteknologin har medfört stora förändringar för dagens företag. Några av utvecklingarna inom IT är Automatic Identification and Data Collection, vilket har inneburit en avsevärd förbättring med avseende på mängden korrektöverförd data. Radio Frequency IDentification (RFID) är en teknologi inom AIDC-området som har börjat användas allt mer, vilket också IKEA uppmärksammat. IKEA är ett multinationellt företag som expanderar kraftigt samtidigt som distributionen blir allt mer komplex, vilket ställer höga krav på ett effektivt och lättöverskådligt flöde. Det förekommer idag många och tidsödande mänskliga fel vid hanteringen av gods vid distributionscentralerna, vilket till stor del beror på olika standards och rutiner för de olika sändningarna.
Utredning av solenergi för drivning av sorptiv kylprocess för inomhusluften på Stockholmsarenan
Cooling down the indoor air can be done in several ways. One way is desiccantcooling which will be used at the Stockholm Arena. This method is used in airhandling units that use temperature changes and moisture fluctuations in the air. Oneof the steps is to add heat during the cooling process in order to reduce the relativehumidity of the exhaust air. The air passes thru an adsorptions rotor which thenabsorbs moisture from the Supply air.
