I have done a follow up study of the restoration of two rivers, Röälven and Grundan, in order to evaluate the effects of the restoration on the endemic population of trout. Both rivers have been used for timber floating during many years throughout the 20th century, and because of this, had all obstacles such as rocks and wood parts removed. In 2004-2005 both rivers were restored, and rocks and wood were put back into the rivers. Spawning grounds were created and boulder dams were constructed to promote the streaming water. The result showed that the trout population of both rivers increased after the restoration, but also that the trout population of Röälven increased more than that of Grundan.

In today's producing companies, there is a high demand on early integrated productdevelopment. One way to facilitate communication between departments and collaborationbetween people and thereby enable early sharing of product information within the companyis to use PLM, Product Lifecycle Management.The CAD environment at Scania is at the moment being upgraded from Catia v4 to Catiav5. In this stage it is important that also the interacting computer systems in Scania?s PLMenvironment are adjusted and in the future join the development. Scania has an idea of howthese systems will be developed as the transition from Catia v4 to Catia v5 is being carriedout.

Föryngring av skog är en nödvändig, men kostsam åtgärd och därför är det eftersträvansvärt att hitta en föryngringsmetod som är både kostnadseffektiv och ger en bra föryngring. Ett sätt att få en billigare föryngringsåtgärd är att använda frösådd. Vid en lyckad sådd gör det stora plantuppslaget att plantorna får bra förutsättningar för god kvalitet. Dessa plantor får dessutom bättre rotutveckling och stabilitet än planterade plantor. Användningen av skogssådd är dock begränsad av bl.a.

Place as a concept, and memory as a phenomenon is researched through literature studies. The essay investigates how we think about place and how we experience and relate to it. Memory is discussed both as personal memory and collective memory. Place is a strong source of memory. When we return to a place, we recognize not only the place itself, but also the things we did there, the people we met and the thoughts passing through our mind when we last were there. Pieces of ourselves are stored in the memories awaken when we revisit a place.

This thesis describes the development ofa linear guidance system suited for NORCAN's aluminium profiles. The work took place at LP Innovation, a small technical consulting company, located in Uppsala. The work started with gathering and searching for information. A lot of the information was found in product catalogs, but my supervisor was also a great source of knowledge, as well as the other engineers at the company. I also had the opportunity to work with the rea lprofiles, to get a feeling and greater understanding how they were supposed to be used. With the use of sketching and CAD, a number of concepts were generated.

The aim of this thesis was to answer a number of questions about the environmental consequences of aircraft de-icing. A further aim was to suggest how the environmental consequences due to the release of de-icing fluids can be measured and reduced.The main impact of the aircraft de-icing on the environment is due to the large oxygen demand for the degradation of glycol based de-icing fluids which are released in the environment. The effect of the increase in oxygen demand depends on where the degradation occurs in the ecosystem. In a sensitive ecosystem, the large demand of oxygen could provide an anaerobic environment which would be harmful for many types of organisms.In order to reduce the negative effects of the applied de-icing fluid, there is some type of collection system at every regular airport in Sweden. The methods of collection can be divided into two general groups, hydrological isolation or vacuum sweeper trucks.

Antalet programvaror ökar för varje dag och människor använder dagligen en mängd olika sorters programvara både på datorer och på andra enheter. Det finns idag programvara som kallas för fri och öppen programvara som tar upp kampen med gamla klassiska proprietära programvaror. Öppna och fria programvaror släpper sin källkod helt fri så användaren själv har möjlighet att göra ändringar i den programvara som används medan proprietär programvaras källkod är skyddad och hemlig. Dessa tre olika sorters programvaror jämförs och diskuteras utifrån tekniska likheter och skillnader i denna kandidatuppsats. Syftet med denna kandidatuppsats inom informatik är att undersöka vad privatpersoner som är tekniskt intresserade har för tankar och attityder kring proprietär, öppen och fri programvara och visa vilka tekniska aspekter som prioriteras vid val mellan dem. I undersökningen har ett kvantitativt angreppssätt bestående av en webbenkät som besvarats av privatpersoner tillämpats. Resultatet från denna enkät har tillsammans med den teori som insamlats visat vilka tekniska funktioner och skillnader som påverkar en privatperson då val av olika sorters programvara ska ske. Undersökningen har visat att det som användaren prioriterar högst i en programvara är användbarheten som handlar om hur användarvänligt användargränssnittet är och hur lättanvänd en programvara är.

The purpose of this thesis was to study local bank offices work with customer satisfaction. A case study concerning two local bank offices was made, the cases were based on interviews with the managers at the bank offices. The research questions that we wanted this thesis to answer was how local bank offices create customer satisfaction among small business customers, and how local bank offices assess customer satisfaction among small business customers. The study showed that local bank offices find customer satisfaction among small business customers important and use complaints as the primary source in the process of creating customer satisfaction..

Discharge of untreated wastewater leads to unnaturally high levels of nitrogen and phosphorus in rivers, lakes and the sea, which results in unbalanced ecosystems with eutrophication and lack of oxygen. Part of the phosphorus in surface waters is coming from on-site wastewater treatment from scattered households with unsatisfactory purification. Blast furnace slag is a by-product from iron production, and has in laboratory trials showed good phosphorus binding capacity. To test blast furnace slag as a reactive filter media for phosphorus separation in a full scale experiment, a wastewater treatment plant has been built behind the picnic area at Ångersjön alongside the road E4 in central-eastern Sweden. The plant contains two parallel lines, one with blast furnaces slag and the other with Filtralite-P as phosphorus sorbent. Both filters have showed decreasing phosphorus purification effect with time in spite of a low wastewater load.

Vaccination of fish can be assumed to cause pain. This study was designed to see if we can minimize the suffering of fish following vaccination. Fishes are cold-blooded animals and thus more primitive than warm-blooded animals. Despite this, many organs, e.g. the nervous system, have the same basic structure as that of other vertebrates. The fibre system for conducting pain is more diffuse than in humans.

The subject of this thesis is the history of the library at The Göteborg Museum of Art. The aim of the thesis is to depict and analyze the emergence and the expansion of the library?s holdings until 1939. To fulfill the aim, two questions are asked. The first question is: Is it possible to argue that the library?s holdings were collected to document the entire world of art? The question is formulated in relation to a comment by Susan Wyngaard.

The last years? financial situation has contributed to an increased willingness from the banks to handle risks. The most important risk to cope with is a risk that is related to a customer?s ability to repay loans. Forecasts indicate that in the future, Swedish farmers will be facing profitability challenges, which points to a need to reconsider the banks procedures considering risk management in credit granting for agricultural businesses.Today?s risk management will be given two complements in this study.

Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.

This is a thesis about an upper secondary  school library and its role as a pedagogkal resour­ce. My purpose has been to find out about the views and experiences of the staff at the school library and twelve teachers at the upper secondary school  conceming the school library as a pedagogical resource. Fourteen  qualitative interviews have been accomplished, twelve  with teachers and the rest with the staff of the school library. All the interviewees seem to think that their school library has an important function as a pedagogical resource and both the librarian and the teachers have given me some examples of occasions when the library has been used as a pedagogkal resource. This school library is mostly used as a complement to other pedagogical resources but for some longer projects with an investigative character it could sometimes be used as the main source according to the answers in these fourteen  interviews..

Mankind has always been communicating, it is almost impossible to not communicate. The communication tree has grown a new branch, the environmental communication branch, and an ISO standard, the ISO 14 063 Environmental communication- guidelines and examples was issued October 2006. The purpose of this thesis is commissioned by the managing director of NQA Nordic AB in order to examine and analyse how organisations communicate environmental issues today, and how big the need for ISO 14 063 actually is, and further more if there are needs and wishes to make ISO 14 063 a certifiable standard. The main conclusion is that the there is a need for the standard, but it is difficult to say in which form since the knowledge about the standard is far to low among the organisations examined in this thesis. Clarity and transparency as ISO 14 063 promotes are important ingredients in organisations? environmental work, so sure a standard for environmental communication can help improve environmental performance, for example through opening up for two-way communication and from that on take part of the stakeholders? opinions.This study is based on a literature study and a questionnaire survey where 70 organisations (in this case authorities, corporations and non-governmental organisations) randomly chosen from the seven criteria, which ISO 14 001 defines as the environment: land, water, air, flora, fauna, natural resources and man and his collaboration with those.
