Trough a literature study based on both philosophic and objective fact this essay is taking off in the meaning of public space. It investigates how the information society and its virtual world are affecting the idea and use of public space in the city. The city and the actual world have developed from the traditional meeting between people while the virtual world is based on flows of information. The information flow has expanded through the Information and Communication Technique (ICT). ICT covers among others Internet, mobile phones and computers.

This report is a literature review that aims to describe marketing contexts for mango production in Kenya. The institutional conditions in the country are not well developed for marketing purposes, which causes many difficulties and problems for the society. In Kenya most mango producers are poor small-scale farmers with limited resources. Mango is a perishable commodity and to keep its value and quality it is essential to have the opportunity to sell the mangos in the right time. Inefficient and undeveloped infrastructure and marketing systems hinders the mangos to reach the market in time though, which causes large losses of produce.The Kenyan mango production has increased during the last decade but due to market losses for the producer, the small-scale farmers? profits have not improved.

Optimizing energy systems is, in Sweden, as in many other countries, of growing interest. District heating systems are no exception. In 2012, 285 out of 290 municipals in Sweden had district heating in use and the majority of these systems have a higher return temperature than that which is possible with an error-free substation of day current technology. To, when possible, lower the return temperature is a way of increasing the effectiveness of the district heating system.This study means to investigate, through simulations and calculations, how big of a reduction in production cost a lower temperature in the city of Ystad?s district heating system would correspond to.

?Development of methods for the planning and implementation of ditch clearing with modern methods?, is a long title for an exam work but that is what this report describes. In Sweden, we have a limited area available, and with the present development with increasing market oil prices, and enormous forces on the renewable energy sources, we need every hectare possible to protect the output of the forests. So with this in mind, many people are now considering how to increase the production of the forests that are already available. A part of production increases is to manage the existing forests, and not to allow this area to go to cultivation or become marshland. We manage our forests in a way that benefits the environment, and we consider that our working practice over the years has shown us to be correct and well functioning. A part of our way of producing forests is to ensure that we have functioning drainage systems in the forest holdings which we administer. The responsible at Holmen Skog requested a good method to make inventories of the drainage systems of Holmen forests. This Degree Project is about ways to identify and implement drainage systems with modern methods. It deals with authorities regulations, and how they operate in different counties.

This study deals with the technical and economic feasibility of replacing the nuclear power plant reactor Ringhals 3 with a biofuel power plant. A technical investigation has been executed to determine which of the systems and components that could be reused and which ones would need to be replaced. The investment costs of the reconstruction have also been estimated. The cost of the electricity production has been calculated as well as the emissions of the new biofuel power plant. Based on the established rate of return, the lowest average spot price of electricity that makes the investment profitable has been calculated.

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..

iPhone belongs to the group smartphones. It is a type of mobile phones that has a richer interface and allows more advanced preformences, i.e surfing the Internet and handling e-mails. This report outlines the work to develop an iPhoneapplication from idea to released product. The project is a thesis which was commissioned by ICA AB (a major Swedish grocery chain). The report includes how the work has been carried out in practice and theory.

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.

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.

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.

Interna privata nätverk har länge använts av företag för att främja kommunikation och informationsspridning genom lokala accesspunkter till intranätet. Då teknologiutvecklingen fortsätter mot en högre grad av mobilitet genom inte bara WiFi, utan även 3G och 4G, har behovet av att utvärdera extern tillgång till företagets intranät blivit allt större. För att uppskatta värdet av extern tillgång av intranät via mobila enheter är det av intresse att identifiera de förutsättningar som skapar ett lyckat mobilt intranät. Det är även viktigt att identifiera potentiella möjligheter till optimering av företagsprocesser som mobil tillgång till intranät kan skapa inom organisationer. Mobil tillgång till kritisk data, dokument eller verktyg kan hjälpa anställda ute på fält.

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.
