This project aims to investigate whether algae can be used for biodiesel production in Italy. Algaes are a good option since they are fast growing and do not occupy arable land. The aspects that have been considered are growing, harvesting, which algae strain that is most suitable, extraction of oil, the production of biodiesel and where in Italy this could be possible due to climate. Cost? and energy calculations have been made to investigate if biodiesel produced from algae would be profitable. During the production of biodiesel there are several residues obtained. When the oil has been extracted from the algae, biogas is produced from the residual biomass by anaerobic digestion and then the electricity that can be produced is supplied to the production of biodiesel.

Traditionally, rolling mills use emulsions based on a mixture of oil and water for lubrication. Since two years ago SAPA has been using (instead of oil) a synthetic lubricant so called conditional emulsion for hot-rolling of aluminum. This lubricant is water based and homogenous at ambient temperature, but switches to a two-phase system at heating above the cloud point.This project aims to validate and if necessary modify an existing HPLC method for quantifying two out of three key components (A, B and C) in the conditional emulsion. Attempts to develop a method to quantify the pH adjusting components, X and Y were also made. These two methods are required to optimize the lubricant.Due to the complexity of the components, it has been difficult to present a method for quantification, and HPLC with ELS detection was chosen after a long series of trials.

Musical improvisation is an infinite artistic well. It helps the musician to make a personal performance and lets the music reflect the inner feelings. It is a language with which the performer can adapt the formulation to the specific situation. Yet so many have fear and respect when facing the phenomenon. In this study Dan Alkenäs discusses the advantages and disadvantages of using musical improvisation as a pedagogical method in school education.

Psychological research concerning correction of stereotypes has mainly focused on how individuals adjust their negative attitude towards the out-group due to the apprehension of appearing prejudiced in front of out-grouprepresentatives. This study though, does not deal with estimations of the qualities of the out-group; it deals with estimations of the qualities of the in-group. Does Swedes correct their estimations of their own group when the experiment leader is of another ethnicity and has a different colour of skin? The participants were students at Halmstad Högskola and they were all born and raised in Sweden. Half the participants got to meet a Swedish born, white skinned experiment leader, whereas the other group got to meet an African born, dark skinned experiment leader.

Within the last year many companies have proactively started to communicate their flaws and weaknesses, believing that this will lead to they being perceived as more personal and human. Dominos Pizza is one of many examples of a company using this practice as a strategic tool for communication. However, the problem concerning the above arises as we found that there was a very limited amount of research defining the effects of communicating flaws, where the company's both dispatcher and initiator. Our study aims to fill the gap between this growing trend and the limited research explaining the communication effects. The study was carried out as an experiment where a total of 420 respondents participated.

Tile covered bathrooms require a wellexecuted waterproofing in order toprotect the underlying construction frommoisture. Länsforsakringar Uppsala paysannually out millions in insurance fordamages related to poor waterproofedbathrooms. In recent years, SP (SwedishNational Testing and Research Institute)investigated and researchedwaterproofing products, resulting ingreater shortcomings of product defectsthan Expected.This report raises the problemsconcerning waterproofing and discusseswhy they occur. By studying productinstructions and insurance cases anddamage reports provided byLänsforsakringar, the most commonproblems concerning bathroomwaterproofing where concluded. Animportant part of the report was tofind out the actual cause to whywaterproofing damages occur.The results of the survey indicate thata common cause of water damage usuallyis related to poor productinstallations.

The purpose of my study was to explore how preschool educators in Kenya look at children's influence on teaching. Researchers have argued that the formal educational system in Kenya today is a remnant of its days as a colony when people were Expected to blindly follow rules without questioning them. I have used qualitative interviews as a method in order get the most concrete understanding of educators? views on the influence from children. The educators I interviewed were based at a school I visited in Kenya.

This degree project investigates how elk, roe deer, red deer and fallow deer can affect an estate in Östergötland. The inventories performed within this project, were completed on an estate in Selesjö, northern Östergötland. This property is used to demonstrate wildlife management. The methods used in this study were originally developed for areas larger than individual properties. Three inventories were completed in the study. These included the recording of the number of droppings and the amount of eaten pasturage, as well as the level of damage on young trees.

The object of interest in this essay is the issue of reducing work hours and how that issue was handled in the Trade Union Confederation (LO). In previous research the struggle for shorter work hours has been viewed as a struggle between trade union and employers? organizations. The previous research has had difficulties in explaining LOs part in this struggle, their actions have not been the Expected. LO had not played an active part in the struggle for shorter work hours and the previous research has not been able to given a satisfying explanation for this.

AbstractBackgroundWorking in primary care with chronic leg ulcers is both time-consuming and difficult. There is a large category of patients with leg ulcers, that is Expected to increase in a number of years, and many of them will probably come to a district nurse for help.AimThe aim of this study was to describe the district nurses' experiences of caring for patients with chronic leg ulcers in primary care.MethodThe approach was qualitative. The study was done with a phenomenological life-world approach. Seven district nurses working in primary care were interviewed. The phenomenological perspective focuses on the respondents? own life-world and has openness to the interviewee's own experiences.

In this paper the authors are trying to understand what separates men from women when they save and invest their money. But also what factors that influence them in their decisions. To investigate how men and women actually act when investing their money the authors construct a survey. The authors also turn to the Swedish banks for information on how they think there customers are behaving. The authors find that men are more risk- taking than women and therefore invest more in products with higher risk, for example shares.

The purpose of this thesis is to determine how well a student is prepared as a future librarian at BHS in Borås, when it comes to serving individuals with hearing disabilities at the libraries. The theory and combined methods is that of discourse theory, interviews and Webb searches. The source material for this thesis comprises course material from 2002 and 2003, with the main focus on the spring term 2003 and on what is called the users perspective användarperspektivet. The study is divided into two parts: firstly, to determine the students Expected knowledge and his/her future professional identity through this knowledge. The user groups that were mentioned to the students during the education were also linked to the students knowledge.

The aim of this thesis was to investigate if the robotized welding method FSW (Friction Stir Welding) could be applied for joining a rotating structure in an aero engine at Volvo Aero Corporation. FSW is Expected to introduce less defects than today?s welding methods and could therefore be suitable for critical aero components. The material is the nickel based alloy Inconel 718, however a material experimentation is outside the scope of this report.The main goal of this study is to verify if the ESAB ROSIO robot based FSW-system has a suitable work space to be able to weld the rotating structure, and if the welding tool has accessibility to the joints. The FSW-process needs a rigid fixture, and a number of fix-ture concepts are presented based on a proposed weld sequence.

From a time where employees often remained at one company until retirement, globalization and changed employment patterns have created a more mobile labor market in the last years. In an effort to expand the connection between organization and employee a rising interest in corporate alumni networks has emerged. Previous research has shown that conditions for such networks are formed through employees social identification, perceived organizational support and organizational citizenship and can be shaped by company's HR practices.This paper aims to examine two case companies' perceived benefits through alumni relations as well as their HR prac-tices, in order to increase understanding surrounding the relationship between the two areas. Further the study intends to draw conclusions about the role of corporate alumni networks in the creation of the received benefits.The study indicates that HR practices, through the creation of an organizational citizenship behavior, can influence the conditions for beneficial alumni relations. Results show that some Expected benefits of alumni relations can be re-ceived through strong citizenship.

The idea of this thesis emerged from our common interest to explore the life cycle of Swedish tourist destinations. This study has historical features since we tried to identify crucial historical and current push and pull factors, which influenced destinations upturns and downturns. In order to achieve our primary goal and identify those factors, we made two case studies. We chose Åre and Mölle as our cases and these two areas will represent Swedish destinations, and their life cycles, as a whole. The destinations? developing processes and their nowadays profile are not the same as for two hundred years ago which was a reason and motivation that made us start exploring this specific subject.
