Uvån Hagfors Teknologi AB (UHT) has developed a process ? GRANSHOT® ? for quicksolidification of metals in water baths. In the process liquid metal is splintered ? granulated ?into small drops. The drops are rapidly cooled in a water bath where all the heat energy from theliquid metal is transferred into the water.

Flow measurement is one of the greatest challenges in order to calculate efficiency in hydropower. Most hydropower plants in Sweden use differential pressure methods for flow measurement. These methods are dependent on constant conditions in the waterways. A change in these conditions, like turbine improvements, prevents differential pressure methods to verify efficiency improvements. Since efficiency improvements can?t be verified by one measurement system, another method, which isn?t affected by changing conditions, can be used.

Deposited waste material degrades within a short period in anaerobic environments. The methane gas that is formed provides a harmful contribute to the greenhouse effect, 23 times larger impact than carbon dioxide. It is therefore desirable to minimize the emissions of methane gas from landfills. This may be achieved by drain the landfill of gas. In this thesis the amount of produced methane gas at the landfill at Örebro has been calculated. Estimations have also been made of the amount of methane gas that might be produced in the landfill in the future.

Warehouses are a key aspect of modern supply chains and play a vital role in the success or failure of businesses today. Figures from the USA indicate that the capital- and operating costs of warehouses represent about 22 % of a company?s logistics costs while figures from Europe indicate 25 % (Baker & Canessa, 2009). Because warehousing is such an important function within a company, the authors chose to focus on this in their thesis. The purpose of this thesis has been to examine the significance of a Warehouse Management System (WMS) and item identification with attention to logistic efficiency.

The past and ongoing structural change in Swedish agriculture has led to an increasing number of large-scale farms. The biological factors associated with large-scale farming operations may cause increasing variability, risk and reduced yields due to sub-optimal timing and management of field operations. The theory of economies of scale suggests that largescale production may benefit from lower costs due to scale efficiencies. Thus, large-scale farms may face cost reductions in terms of long term inputs factors, e.g. agricultural machinery.

This bachelor?s thesis aims to examine how the ?New Pact on Migration and Asylum? construct the discourse on ?sustainable migration? and ?efficiency? in the European Union. The new jurisprudence concerning migration and asylum in the European Union seeks to establish a more ?fair, efficient and sustainable migration and asylum system?. To analyze the discourses, a critical discourse analysis is applied to the former asylum regulation, Dublin regulation III, a revised and withdrawn proposal, Dublin regulation IV, and future legislation.

The purpose with this essay is to evaluate the retrieval performance between Googles basic search and the advanced search functions. A secondary purpose is to evaluate the differences between the binary relevance scale and a 4- point scale. The basic search is defined as a search with two terms combined with the Boolean operator AND. The advanced search is based on search functions that are adequate to compare to the basic search. They are categorized as AND-searches, OR-searches, AND and OR-searches, exact phrase, and depending on where the terms occur on the page.

Information technology (IT) with its enormous capacity involves more and more in our daily activities and public sector is using IT to make their activities more efficient. The government goal with electronic government (e-government) among other things is increasing the availability and service to the public as well as improving the democratic process. Democracy can be strengthened by involving citizens in public decision making process but this goal has not been achieved yet and the development of e-government has mostly been focused on improving efficiency within administration and electronic services (e-services). Promoting the democratic process has been postponed in the development of e-government because of the lack of political commitment and decision. Digital divide is also preventing public sector to promote democracy with the support of IT.

The goal of this project was to make the requirement process at the Swedish Coastguard more effective. The first step to achieve this was done by locating bottle necks in the process with value stream mapping method. The result of this study showed that the biggest restriction in the requirement process was while examining older requirement documents to understand what elements were suitable for the particular project. This was followed by a study of literature, interviews and theory of Lean Production with the ambition to investigate how the requirement process was handled on other companies and how to improve the process on the Swedish coast guard. This led to a number of potential enhancements of the process which later was evaluated. Requirements written by different people in different organizations were analyzed in order to sort out if there were some similarities? which could be used as standard elements in a future standardization of the process.

In the production of pulp, paper and cardboard, a large amount of water is used daily. The water has to be purified in the internal purifying plant before it reaches the receiving body of water. In the biological purifying stage at the Stora Enso Skoghall mill, an aerated basin is used where the microorganisms, using oxygen, oxidize the organic material to carbon dioxide. The air is pumped from the bottom of the basin and the oxygen can then be transported from the air bubbles to the water through diffusion. The problem with aeration of waste water from the forest industry is that wood residues, such as fatty acids, are making the transport of oxygen in water more difficult.

Forest fertilization had its peak in the late 60´s, when almost 200 000 ha was fertilized annually. The silviculture of today has high demands for timber production at the same time as the demand for nature conservation increases. It means that it?s necessary to produce more volume in smaller areas in the future. The use of DGPS equipment has in modern forestry in Sweden become more and more common.

Chewing behaviour includes both eating and ruminating activity. Chewing behaviour is of great importance for the feed intake as through the action of chewing (i.e. eating and ruminating) animals mechanically process the forages in small particle sizes and prepare the food for digestion. As cattle grow the chewing behaviour changes along with increasing body weight and chewing efficiency is increased. The aim of this thesis was to review the available scientific literature in order to describe chewing behaviour in growing cattle, as well as the factors that affect this behaviour.

This master thesis in energy optimization was made during the autumn of 2006 at Käppala wastewater treatment plant in Lidingö, Stockholm. A preceding thesis, where all electricity consumption was mapped, showed that the aeration in the biological treatment is the single largest consumer in the plant, and it is therefore of interest to reduce this cost. The oxygen control strategy used at Käppala WWTP is working well from a nutrient removal point of view, but not from an economic one. The last aerobic zones have a very low oxygen consumption during low loading periods which give rise to enhanced dissolved oxygen concentrations with excessive costs and reduced denitrification as a result. But also during periods of normal loading unnecessary high oxygen concentration are sometimes given.By modifying the aeration control strategy three full-scale experiments have been made, with the intention to reduce the air consumption.

Denna studie behandlar begreppen process och produkt. Syftet är att genom ett hermeneutiskt perspektiv undersöka några bildlärares syn på begreppen process och produkt i bildundervisningen på högstadiet. Tidigare har fokus legat på elevers färdiga produkt men idag är bedömningen i bildämnet mer fokuserad på elevers process (Skolverket, 2012:3). Undersökningen genomfördes genom  kavlitativa intervjuer. Intervjufrågorna är förankrade i Lindströms (2002:4-5) process- och produktkriterier.

The study aims to illustrate how women victims of male violence in intimate relationships are treated during the legal process and with professional perspective describe what women?s experiences considered to be in the legal process. The study also aims to draw attention to the interventions for abused women during the legal process.The results are based on interviews with professionals in the justice system, and on observations in the courtroom. Overall our results show that abused women are in need of a great quantity of help and support before, during and after the negotiation. The legal process is very stressful for the women.
