The prevailing food and energy crisis of the world, due to the declining reserves of fossil energy and a never ending rise of consumption, forces us to look into new fields to supply our energy demand. The boom of bio energy is criticized, as food crops are used to provide biodiesel and ethanol and the volumes are ridiculously small to supply world demand. Algae are one of the world?s oldest life forms and exist in many different phyla, providing a great variety to choose from, for different purposes. Cultivating microalgae offer a way to produce energy at great volumes without competing with food production and at the same time the algae offer a way to use our expensive nutrients in a more efficient way, besides this the algae are carbon dioxide neutral since their carbon source can be supplied by the atmosphere and the additional energy required can be supplied by algal oil or other renewable sources.

Background: One of the largest direct selling companies Amway "AmericanWay", which has its foothold in the market economy by means of direct trade. This means that the marketing is in the form of a network made up of various individuals who work together to advertise the company on to various potential customers.Aim: The survey aims to study the factors that are affecting the company Amway's growth.Completion: The survey is based on analyzing the interviews. The authors have relied on the qualitative method, where they have focused on how growth has increased the company Amway.Results: The results of this study are that Amway gradually managed to establish themselves globally thanks to the quality of the products they sell in a functioning market. The study also shows that all member customers are satisfied with the goods they buy from ABO groups, and that Amway's structure is not based on a pyramid scheme..

In this thesis ? concerning didactics of literature ? I perform a reading and theoretical analysis of two pivotal works within reader-response theory, more precisely: Literature as Exploration (1938) and The Reader, the Text, the Poem ? The Transactional Theory of the Literary Work (1978), both written by Louise M. Rosenblatt. The object of this analysis is to examine whether Rosenblatts? theory and methodology can be used to accomplish understanding for ?the other?, what Martha C.

Problem: What are the characteristics of Polykemi?s management control system and how is it affected by growth? Purpose: To describe and analyse the management control system of a medium-sized family-owned company from the perspective of Simons? Levers of control. Research design: An abductive, interview-based case study of Polykemi AB. Conclusion: Polykemi?s management control system is primarily a traditional one which is rather strong in terms of Levers of control.

The aim of this Master?s thesis is to examine the librarians? perception of the users of children?s and young people?s literature. Questions posed in this study are: How are the librarians described according to appearance, personality and interaction with the users? How are the librarians described compared to former studies on the subject? Which perception can be seen, based on Douglas Rabers?s theory which describes the role the public libraries can take in the society? The study is based on content analysis. We have examined 15 descriptions of librarians in both picture books and literature for young adults, published between 1985 and 2006.

Feline infectious peritonitis (FIP) is a feline viral disease with high mortality. There is no cure or any effective vaccine available today. Many questions are yet to be answered about this disease and the immune response in affected cats. The aim of the study is to evaluate two different techniques for the study of cytokine profiles in cats vaccinated with a vaccine concept against FIPV. More information about the immune response in these cats could give valuable information to better understand the pathogenesis of the disease and the development of an effective vaccine.

Crowdfunding is a phenomenon that is subject to a great growth during the recent years, and the growth rate doesn't seem to stagnate. When new legislation named the JOBS Act in the U.S. becomes effective in late 2015, crowd equity will surely become a popular tool for financing businesses. Because crowdfunding great popularity is caused by the possibility to reach out to crowds through the internet, it is a global phenomenon, why it's relevant to examine current legislations in jurisdictions. This thesis covers an examination of Swedish laws of how they govern crowdfunding, and also suggestions on how the laws should be changed to more efficiently  correspond with the purposes of crowdfunding..

It is popular to keep reptiles as pets in Swedish households. The number of households reporting reptile ownership is more than 15 000 (SCB, 2006). This means that a veterinary practice should consider how to take care of reptiles as patients. The aim of this study was to examine literature and studies concerning safe handling and restraint of reptiles as well as the effects of acute and long term stress response and to suggest a simplified plan for handling reptiles in a veterinary practice. The result of literary studies is that common recommendations for safe handling and restraint of reptiles is based on old techniques and experiences from safe handling of wild animals. The main concern is safety for the veterinary nurse and for the reptile. Stress studies indicate that acute stress response is not harmful for the animal i long term. On the other hand studies of the effect of prolonged stress are not conclusive.

The popularity of vegetated, or green roofs, has grown over the past years due to their potential function of maintaining urban environment quality. The aim of this study was to investigate if substrates with different organic material, peat and charcoal, with two contents (3 or 6 weight%) influenced the growth of the cuttings during the first critical period of the establishment. Biochar is used as amendment to agricultural soils and has, theoretically, many of the properties suitable as organic content in green roof-substrates. Peat is one of the materials that is commercially used in green roof industry. The substrate has been treated with different amounts of water.

The daily travel, and especially travel between home and work i.e. commuting, is increasing every passing year. More than 90 000 people commute from their home municipality to work in Gothenburg. One of the aims of the regions of Västra Götaland and Halland is to interconnect municipalities and towns within the region, thereby creating growth, faster freight and passenger transports as well as a more attractive business climate. However, while the goal is to create growth, there are several municipalities in the study region with negative ongoing trends.

Burnt alun shale and lime is the residual product that was formed when alun shale was used as fuel to convert limestone to quick lime. The material contains arsenic, vanadium, molybdenum, cadmium, nickel, lead, and uranium among other elements. The aim of this paper is to examine the uptake of trace elements in vegetables grown on burnt alun shale and lime to determine whether or not the surrounding environment and humans are exposed to these elements by eating plant products. A cultivation trial was carried out where onion, carrot, and lettuce were grown on three mounds of burnt alun shale and lime in the Falköping area in Sweden. The treatments were burnt alun shale and lime mixed with peat, only burnt alun shale and lime, and a reference soil. The reference plots were natural soil mixed with peat adjacent to the mounds.

The main purpose with this study was to investigate whether the tree growth differs or not in prescribed burnt areas compared to mechanically scarified. Together with the result from the main purpose, answers of whether it's possible or not to combine nature conservation with tree production in prescribed burnt areas was presented. In these areas the regeneration were analyzed to see if there was enough tree plants to comply with the Swedish Forestry Act regulations terms for approved regeneration. A field survey was conducted at 6 objects, three objects for prescribed burning and three for mechanically scarification. All objects were planted within the same year.

The eutrophication of inshore seas, lakes and watercourses is mainly due to leaching of nitrogen and phosphorus (P) from agriculture. Many efforts are made to reduce the lea-kage of phosphorus in Sweden and the Baltic Sea countries. Phosphorus is also a finite resource and the mining of good quality raw material gets more and more difficult. Se-dimentation dams in combination with filters is one relatively new method to separate P from run-off and drainage water from agricultural land. This study was a part of an IVL Swedish Environmental Research Institute?s project which tests the capacity and func-tion for separation of phosphorus in four phosphorus filters.

Pharmaceuticals are environmental pollutants that are a major threat to aquatic ecosystems and very little is known about their ecological consequences. In this study growth, survival and behaviour (sociability, activity and boldness) of perch fry (Perca fluviatilis) were examined in order to study the possible effects of exposure to a benzodiazepine anxiolytic drug, Oxazepam, during embryonic development. The study tested following hypotheses: (1) perch growth is affected positively by exposure during embryonic development; (2) early perch survival is affected positively by exposure during embryonic development; and (3) boldness and activity increases while sociability decreases in perch fry exposed during embryonic development. Embryos of naturally spawned perch were exposed to water with two different concentrations of Oxazepam. The embryos were exposed during different parts (24-hour periods) of the embryonic development, because embryos may be more vulnerable at certain times during embryonic development and/or because the exposure at different times can produce different effects.
