Within agriculture it is important to optimize the use of nitrogen, not only from an economic point of view but also to minimize damage to the environment. This can sometimes be difficult, especially within organic farming. Organic farmers are using increasing amounts of waste products from the food industry to cover their nitrogen needs. These different organic fertilizers release nitrogen at different rates and under specific soil conditions. Because of this, it would be beneficial to have a standardized method to measure the amount and rate of nitrogen mineralization from organic fertilizers. This project contributes to this knowledge by investigating whether relatively simple and repeatable laboratory methods can be used to estimate the nitrogen fertilizer value of organic fertilizers.

Genetic parameters for four leg conformation traits in dogs (Canis lupus familiaris) are in this literature review summarized to investigate whether selective breeding could be useful to improve purebred dogs´ health and welfare. The four traits are leg length, leg weakness, hip joint and elbow joint conformation. When summarized, the genetic parameters are compared with genetic parameters affecting in pigs (Sus scrofa). Of the four traits, hip and elbow conformations were mostly studied in dogs. However, these traits were not widely studied in pigs.

Abstract This paper discusses protectionism of intellectual property rights in general and the conflict between large pharmaceutical companies? rights to patent and developing countries? rights to cheap generic preparation in particular. The essay focuses above all on HIV/AIDS medicine. The description tries to give an image of the different interests that collide and why they collide. The different actors are above all the pharmaceutical branch, including researchers, inventors and salesmen with their economic interest of revenue, and the population of the development countries and their pressed situation considering the great need of medicine.

Unlike the manufacturing industry, the construction industry is always in motion. Each new construction project brings new opportunities, and it requires a new plan, new organisation, and new suppliers. All construction projects are very different from each other and in terms of a logistical perspective, this is very weak as it makes it difficult to get a flow in the production and to make flawless routines. The way the external and internal logistics are managed, can effect the final product in the time taken to produce it, the quality of the product and the profit made from it. When internal logistics are handled poorly, it could result in materials not being at the right place at the right time, or information not going through to the right person.

In the farrowing pens the amount of bedding material and the quality of the concrete floor has a huge impact on both the sow and the piglets. In this study imbedding of rubber flooring on the solid area in the farrowing pen was used to see if it had any effects on the sows lying behaviour when compared to concrete. Another important aspect was to evaluate if the rubber floorings had a high enough durability to resist the normal wear in a farrowing pen. Concrete flooring is assumed to have a higher thermally conductive effect then rubber which can affect the sow?s chance to cool down.

During the late 1800s fire suppression became increasingly effective in northern Sweden which led to decreased areas of fire-disturbed woodland and successive changes in the structure of forests. In the long run this can pose a serious threat to fire-dependent and fire-favored species. Today some fire-prone forest reserves are burned as a nature conservation act. Often partial cuttings are made before burning, with somewhat different motives. The purpose of the study in Långsidberget nature reserve was to give a general picture of forest history and its affect on today?s forest condition, and to show how partial cuttings affect burning conditions and results. Långsidberget is located close to areas that were colonized during the Middle Ages.

We have left the industrial society, and instead, we live in a post-industrial knowledge and information society. It is often said that industrial production has disappeared or that it has changed greatly. This means that fewer are employed in the manufacturing sector while the service sector is increasing, resulting in that the boundaries between production and administration decreases. The production goes from mass production to more flexible and specialized solutions. This puts greater demands on the logistics chain that continually need to work to meet customer requirements.

This master thesis is a study of the Swedish hydropower capacity to balance wind power. The Swedish government has decided that it should be possible to produce 30 TWh from wind power in the year 2020. The Swedish municipalities have to have plans for wind power plants with total yearly generation of 30 TWh. Wind power is an variable energy source that needs to be balanced by other energy sources. In Sweden the Swedish hydropower can be used for balancing a large scale introduction of wind power.

Business is changing and so are society?s expectations. Companies are expected to take responsibility for their trade and the context they are operating in, by looking at socially, economically and environmentally aspects. Many companies handle it by implementing corporate social responsibility (CSR) to their line of action. This is often handled by collaborating with other organisations, such as non-governmental organisations.

AbstractPolymetallic (Pb-Zn-Cu-Ag-Au-Sb-As-Bi-Cd-Te-Se-Ge?) quartz veins occur in an area from Eidsvoll in southeastern Norway to west of LakeVänern in southwestern Sweden. They most likely formed during the waning stage of the c. 1 Ga Sveconorwegian orogeny. In Värmskog parish, Värmland county, several mineralized quartz veins of different types are known.

Pets like dogs and cats have a considerable importance for humans and research demonstrate a variety of positive economic and social effects in society due to our pet companions. The presences of pets are increasing on a global scale with correlation to economic development in low- and middle income countries. For example dogs have doubled in India over a five year period. The feed industry for dogs and cats is also the fastest growing sector in the food industry and certain pets have a significant animal protein intake which, depending on the choice of resources may provide a high ecological footprint. Examples of environmental effects with distribution and manufacturing of pet food are increased greenhouse gas emissions, waste, use of water and energy.

A great deal of the nature experience we get today is from travelling along our roads, which to a large extent go through the forest landscape. This makes the forest along our roads interesting to look at from a nature experience perspective. The main idea of this work is to increase the awareness of how we are affected by the forest when we travel through it and find out how the forest should be adapted to the road environment to create a pleasant nature experience as well as increase traffic safety. 0.9 % of Sweden's total forest area (equivalent to 200 000 hectares) is in close proximity to roads. Additionally, in Sweden 440 million hours are spent behind the wheel of which a great deal probably is spent on roads surrounded by forest in some form.

Studiens syfte har varit att undersöka färgens betydelse i skolslöjden. Vi har reagerat på att färg används i begränsad omfattning dels i lärarutbildningen men även i grundskolan. Vi efterforskar förklaringar i slöjden och slöjdlärarens historia. Genom bakgrundsfakta om färg vill vi åstadkomma ett ökat intresse för användandet av traditionella färger och ett laborerande arbetssätt. Färganvändning kopplas till kursplanen i trä- och metallslöjd och tydliggörs i diskussionen.

Urban trees have very little in common with trees on natural sites, such as forests or pastures. Trees in urban environments are often planted in packed soil and in small volumes. This can lead to decreased availability of water and oxygen, as well as deteriorated ability for the soil to store nutritional elements. Also above ground the tree usually have limited space in cities. Regulations on free height over roads and cycle tracks demands high stems at an early stage of their development.
