During 2007 the City of Stockholm installed five grid connected photovoltaic systems. The aim of this master thesis is to quantify the amount of produced energy and recommend routines to collect and analyse production data, to make production data accessible by the public and to gain experience for future installations.The total amount of produced energy until March 2009 is 227 000 kWh, with an annual rate of 150 000 kWh. The expected annual rate was 148 000 kWh.All system owners are positive about their plants and see economical benefits in scaling up such systems.The installations need very little attendance and maintenance, however it is recommended that an alarm function is installed for automatic feedback in case of a system failure. All future systems should be inspected during full operation to determine if the actual capacity is matching the installed capacity..

To achieve the requirements to decrease emissions of greenhouse gases by 20 % by 2020, Swedenneeds to increase its use of bioenergy. In doing so it seems natural that those who already haveaccess to large amounts of biofuels in the form of by-products such as straw, wood chips anddigestible materials take advantage of these assets locally. By combining production of heat withpower production at the farm it may be possible to not only reduce the direct use of fossil fuel forheating but also reduce energy costs.The purpose was to simulate different cases of using a small scale biofueled combined heat andpower plant for farm-based systems. A MatLab-model was developed and used to draw conclusionsabout the costs for production of heat and electricity with different conversion technologies.The model uses climate data to simulate the variations in heat energy demand on a day-to-day basis.The given heat demand is the base of the simulation and from this the possible electric output iscalculated. This study has focused on the impact of the following properties: electric-, heat- andtotal efficiency, fuel, fuel price and specific fuel requirements.

A Swedish company, company F, will establish a new factory in China. Company F is adivision within Company F. The factory in China will manufacture wire products. Thepurpose of this final thesis is to analyse which legal and practical measures the company hasto undertake during the process of localization to get approval from the Chineseenvironmental legislation.An analysis of the influencing factors on the environment from the production in theconstruction in Sweden was carried through. A material-balance was analysed according tothe flowchart of the production.

The reindeer planning system (Renbruksplanen, RBP) is a communication and planning tool designed for Sami groups. A key purpose of this is that it will act as a tool in consultation with other market players, including forestry. Sami groups have asked for a model of how this can be used in a flexible manner. With the Swedish Forest Agency as a project manager, a communication model for how to use the RBP has been designed. It consists of a number of points divided into ?before?, ?during? and ?after? the consultation.

Syftet med denna uppsats är att undersöka relationen mellan de två nationella miljökvalitetsmålen, Ett rikt odlingslandskap och God bebyggd miljö. Sveriges mest högproduktiva jordbruksmark finns till stor del i Skåne. Skåne har sedan 1960-talet haft en positiv befolkningstillväxt större än resten av landet. Kombinationen mellan stor andel jordbruksmark och positiv befolkningsutveckling gör Skåneregionen intressant att undersöka. Uppsatsen görs i form av en forskningsöversikt och en fallstudie av Tomelilla tätort. Fallstudien består av planeringsförutsättningar där kommunala och regionala dokument samt lagstiftning med mera behandlas. Vidare görs en scenarioanalys genom scenariokors, en utvärdering av Tomelilla kommuns översiktsplans utbyggnadsförslag för Tomelilla tätort och en realistisk byanalys. Uppsatsen visar att det finns en vision att kombinera de två miljökvalitetsmålen Ett rikt odlingslandskap och God bebyggd miljö men att det finns en skillnad mellan vision och handling när det gäller bevarande av jordbruksmark vid bebyggelseutveckling. Tät fysisk struktur identifieras som en struktur som tar hänsyn till jordbruksmark vid bebyggelseutveckling. Uppsatsen avslutas med en avslutande diskussion av mer fri karaktär, diskussionen tar upp behovet av verktyg för förtätning och frågan om en större arena för planering av hushållning med jordbruksmark behövs..

I Skåne pågår i dagsläget planeringsarbetet för spårvagn i de tre största städerna; Malmö, Lund och Helsingborg. Hur kommer det sig att samtliga Skånes tre största städer med så pass olika förutsättningar och storlek planerar för spårväg samtidigt? Är det ett resultat av ett ökat resande eller finns det andra, mer visionära faktorer som styr? Arbetet syftar till att undersöka och jämföra tre städers val av spårväg utifrån de undersökta städernas visioner och morfologiska förutsättningar. Vilka är de avgörande faktorerna i valet av kollektivtrafik, hur motiveras valet och vilka effekter förväntas ett sådant val ge staden? Den övergripande frågeställningen är; hur motiverar de studerade kommunerna att planera för spårväg? Tre fallstudier har genomförts i studien för att möjliggöra jämförelser mellan fallen. Det finns spårvägsplaner på flera håll runt om i landet så som i Linköping, Uppsala och Jönköping.

En utbyggnad av shared space har skett och sker runt om i Sverige, Europa och övriga världen. Utbyggnaden har föranlett en debatt kring ämnet som handlar om stadens funktion och om människors tillgång till staden utifrån sina villkor. Det finns ett kunskapsbehov i kommunal planering när det gäller utformning och val av plats för shared space, vilket är en av anledningarna till examensarbetet. Syftet är att formulera och pröva en arbetsmodell som kan vara vägledande i arbetet med etablering av shared space, där fokus ligger på prioriteringar mellan användare och begreppen: stadens karaktär, tillgänglighet, trygghet, trafiksäkerhet och miljö. Dessa utgör kvalitetsbegreppen i planerarhandboken; Trafik för en attraktiv stad.

Worldwide consumption of cheese has increased over the years. The average Swede consumes somewhere around 20 kilograms of cheese per year, which is an increase of a 100 % over the past 50 years. One of the most popular kinds of cheese during the past decades is mozzarella, due to its? use as pizza cheese. Flavor and consistency differ between the traditional kind, made out of buffalo?s milk, and the industrially made kind, made out of cow?s milk.

Research in solar energy is taking big steps in both solar heating and solar electricity. It´s not only the technologies alone, but also the combination of both solar electricity and solar heating which is what is called a solar hybrid. The idea of a solar hybrid is that a solar cells efficiency decrease with increased temperature and can with help from a solar collector be cooled and the heat can be utilized. This thesis report compares heat production and electricity production with respect of, in first hand, a solar hybrids geometry in the cooler. The theory chapter describes solar heating and how different solar cell technologies work and their environmental impact at the production and how compatible these technologies are for the solar hybrid.

Conqueror for Indigo is production treated with an active chemical to maximize the ink adhesion.ArjoWiggins has found that another chemical, the candidate compound, would improve the propertiesof the paper. ArjoWiggins therefore wish to replace the current compound. To strengthenthe patent requirements for ink adhesion needs to be determined. A theory is developed to whychemicals with certain properties maximize the ink adhesion. Experiments are performed but theresults are inaccurate.

In Sweden in January 2005, there is only one producer of organic broilers and none of organic turkeys. But there are, on the other hand, a few small-scale producers whose housing systems to some extent are similar to what is stipulated in the organic standards. The aims of this work are to investigate what housing systems are used by the Swedish small-scale producers of broilers and turkeys, what main challenges they are confronted with and if there is an interest and a possibility for a change-over to organic production. For the first part of this work a literature study was performed with the purpose of detecting the main health problems in conventional as well as smallscale production. A special focus was on coccidiosis and leg weakness as those were considered to be of particular importance. A study was made of Swedish small-scale poultry production units. In two groups of broilers from the same producer and in three flocks of turkeys the level of Eimeria oocysts in faeces and litter was investigated.

In developing countries such as Vietnam the population consumes more animal products for example milk and meat than before which requires greater livestock production. Ruminants contributes to more methane emission which creates a dilemma between food production and its environmental impact. By feeding ruminants with nutritive crops which humans can not assimilate the animal performance will increase in terms of better growth and milk production without inpinging on food that can be consumed directly by humans. Increasing animal performance reduces methane emission in terms of amount of methane in kg-1 milk and meat which today is much greater in developing countries than developed countries. The aim of the study was to investigate tropical tannin-rich legumes for their potential as a feed supplement for ruminants made in vitro.

On today?s competitive market, it is difficult to achieve profitability trough high prices on manufactured products. Profitability must be obtained through low manufacturing costs, high quality and short lead times. One of the companies on the market is Sandvik Coromant, manufacturer of tools and chips for metal cutting. This master thesis investigates the methods of manufacturing for boring bars at the manufacturing unit GVH4 at Sandvik Coromant in Gimo, Sweden.

When an error occurs in an IT system that is vital for the production of a major industry, the consequences can be great. To quickly identify and correct errors is important as a stop in a system can lead to a break in production, which is costly for the industry. Our task in this thesis has been to develop a system for ÅF that facilitates the debugging process of the system Paperline. The system's target audience is ÅF-call personnel that provides support for Paperline 24 hours a day if something goes wrong. The system consists of a Windows service, a database and a web application and is developed mainly with the techniques C#.NET, MVC 5, Google Charts, Javascript, HTML, CSS, and Entity Framework.

This report is focusing on problems with introducing standard enterprise resource planning systems (ERP) in businesses.
