Global catch fishery is said to been oppressed to its limit (Boyd & Schmittou, 1999), further implying aquaculture might be the only solution to the world demand for fishery products. The applied term aquaculture in this paper refers to the one used by NOAA (2008); breeding, rearing, and harvesting of plants and animals in all kind of water environments, including but not limited to ponds, rivers, lakes, and the ocean. According to Shamshak & Anderson (2008, p. 74) aquaculture has over the past 20 years been the fastest growing food sector with an average annual growth rate of 8.7%. It further represents approximately 37 % (Shamshak & Anderson, 2008, p.

Modern sawmills are using the raw-material and the production-capacity more efficiently today, due to rising raw-material prices and higher production costs. Log sweepness has a negative effect on the sawn yield, for sawmills with straight-sawing. It is desirable that these logs could be sorted based on more criteria, if it increases value-yield and consequently the utilization of raw-material. Bow-heights over 1 cm have a negative effect on sawn yield, since the surface of the mantle cuts down in the sawn pattern. Some of these small bow-heights reduce the logs yield of value which affects the production planning negatively. Nearly half of all the Swedish logs have a bow-height over 1 cm.

In Sweden, the most common way to castrate a bitch is by midline approach. In this study, flank and midline approaches are compared in order to evaluate incision by the flank as an alternative technique for ovariohysterectomy in the bitch. The study was performed on straydogs in the central part of Thailand under field conditions. 32 bitches were included in the study. The castration technique was by flank and midline approach, alternating with every other bitch.

The housing sector uses 40 % of the energy in Sweden and half of the electricity usage. Theuse of energy is the main reason to the increasing rate of carbon dioxide in the atmosphere.This is the main motive but also a wish of higher safety, that is a higher rate of selfsufficientenergy production in Sweden, we want to decrease the need of using fossil fuel. Now whenthe energy price rise, the interest in energy issues increase and more people discuss thepossibility of reducing the usage of fossil fuel. A change to renewable energy such as sun,wind and water is the only solution where we can get a sustainable development.One way to contribute to a better use of energy is to build in the principle of passive house.The house is being built with a thick and tight insulation. If you use a heat-exchanger withhigh degree of efficiency and a final heating battery on the ventilation system, the heat fromlamps, devices and the ones living in the house should be enough to fulfil the criteria ofliving.

Tacit knowledge refers to the knowledge that is located inside individuals; it is not expressed or written like explicit knowledge. Inherently, tacit knowledge is often limited solely to one person and consequently individually based. Project based companies need to acknowledge the importance of transforming tacit knowledge into explicit in order to preserve the knowledge inside the organisation. If the knowledge is not transformed, there is a great risk of losing the knowledge when a key individual leaves the organization.One way of transforming the tacit knowledge is through Nonaka?s and Takeuchi?s knowledge spiral.

The purpose with this article is to give examples how to remain and in a long run develop a higher interest in maintenance activities and knowledge. First reason is the changed age-distribution with more number of older employees among maintenance personnel staff and second reason is demand for education due the increasing demand in environmental responsibility.In spite of there is a lot of knowledge of maintenance in national organizations of interests it will not be used in a sufficient extent in many companies. This knowledge is an important base to use to re-built the missing or loosed skills in companies. The national organization UTEK is involved in European projects to validate knowledge of maintenance. Lost of or bad maintenance activities will always affect on the environment.Establish a network between companies is a good way to exchange information in their common business areas.

1.1 billion people are today living without sustainable access to improved water. The debate over the water sector has been dominated by the discussion over whether public or private actors are the most competent to manage it. In this paper the arguments pro and contra the two positions are presented to try to overview the debate and to try to find new ways to approach the question of the people living without clean water. By examining possible alternatives towards the discussion of public and private actors, it might result in some new approaches on how to move closer towards a solution. One alternative is local, small- scale projects which focus on the situation of the targetgroup in most need.

According to the theory of environmental Kuznets curve there is a relationship between carbon emissions and GDP. The relationship has an inverted U-shape. Carbon emissions rise initially and then decreases once a certain level of GDP is obtained.This essay interprets earlier studies in the field of environmental economics and uses public choice to seek answer on how the population acts on aggregate level. This essay analyses 115 countries in cross-sectional data. The analysis shows that there is a significant relationship between carbon dioxide emissions and GDP that is increasing at first and then decreases for a certain level of GDP.

The Earth and everything else in the universe was created in the Big Bang around 14 billion years ago. A point with tremendous density and mass began to expand and more and more atoms began to form. From the first and lightest like hydrogen and helium to heavier atoms such as iron and eventually gold. The formation of the Earth occurred about 4.6 billion years ago and so the first gold atoms were concentrated only here. It is however believed that much later in Earth's history an extra supply of gold occurred thanks to massive meteorite bombardments.

I detta examensarbete har jag undersökt förmågan hos nautiker att ta fram och tillgodogöra sig information från radar och ARPA för sitt beslutsunderlag i trafiksituationer. Syftet var att få förståelse i om fartygsbefäl haft svårigheter att få fram denna mycket relevanta information. Detta gjordes med hjälp av förstudier i form av intervjuer med erfarna fartygsbefäl. Dessa intervjuer gav kriterier som möjliggjorde analyseringen av 13 olycksfallsrapporter, vilket utgjorde litteraturstudien. Dessa rapporter var författade av engelska Department of Transport, Marine Investigation Branch(MAIB), Statenshaverikommission(SHK) och  Sjöfartsverkets rapportserie(SjöfR).

This essay analyses the act of reading August Strindberg?s novel En dåres försvarstal (A Madman?s defence). It reveals the writer?s motif and purpose with the text and it shows how a certain interpretation of the text is crucial for the writer?s intentions to become reality. But it also shows how this interpretation is threaten by several, both intertextual and extratextual, thematically and structural, factors.

This study focuses on romantic friendship between women in three Swedish novels written between 1836 and 1857: Sophie von Knorring?s (1797?1848) Illusionerna (1836), Fredrika Bremer?s (1801?1865) En dagbok (1843) and Marie Sophie Schwartz? (1819?1894) En fåfäng mans hustru (1857). Also, the connection between women and passion as well as the interesting occurrence of step- and foster mothers is looked upon in the study.The romantic friendship is freely expressed in these novels; love between women is neither presented as unnatural or unchaste. It both challenges the heterosexual matrix? claim on intelligibility and its rules for how desire should be expressed.

Generally, the economic health of Swedish roundwood truck transport companies has not been good. Profitability is important for maintaining the stability in the transport business, which is a condition for long-term transport planning in the forestry sector. The scope of this study was to identify probable factors influencing the profitability of roundwood truck transport companies and quantify the influence of these factors on economic results. The study was carried out at a major roundwood truck transport organisation in mid-Sweden and was implemented in four steps. In the first step economic results from the haulage contractors were collected and a random sample was taken from accounted net margin for the account year 2005/2006. In the second step hauliers were interviewed to identify probable success factors. At the third step data for identified factors were gathered through a questionnaire.

The most common way to treat wastewater in Sweden today is by a combination of an activated sludge process and a chemical treatment. These processes are not very energy efficient and may not be the most environmentally friendly. That is why it is interesting to evaluate new alternative methods to see if they can be less harmful to the environment and help to a lower resource consumption. New techniques are tested in a pilot installation at Hammarby Sjöstad, Sjöstadsverket. To be able to evaluate these techniques in a wide perspective system analyses are conducted where different impacts can be considered, advantages and disadvantages in the systems.Five system structures for water treatment have been constructed in Matlab/Simulink in this study.

Rupert Marine tillverkar och säljer RIB-båtar, som är små snabba båtar med riktigt, stelt, skrov och uppblåsbara tuber runt skrovkanten. Bakgrunden till denna masteruppsats är att det ofta finns stora brister i förarmiljön och förarplatsernas utformning på båtar. Företaget upplever att man har en lucka i sitt utbud av stolar. Det saknas en komfortabel och multifunktionell stol för fritidsanvändare. Det finns företag som tillverkar stolar separat för mindre snabba båtar.
