Effektiviseringspotential inom industrisektorn : Energibesparing vid frekvensstyrning av centrifugalpumpar ? en fallstudie
The project was performed at SiemensIndustry Drive Technologies with theobjective to provide actual values forthe energy savings potential withinSiemens scope of practice.In Sweden the electrical drives standfor about 30 % of the total electricityconsumption and about 60 % of theelectricity consumption within theindustry. During the pre-study phaseelectrical drives with pump applicationswere identified as large energy users.Because of this a case study at one ofSiemens customers, Stora Enso Fors wasperformed. The system that was evaluatedduring the case study was a throttledsystem with a centrifugal pump forpumping pulp.The results yielded that a saving ofover 50 % could be achieved by replacingthe throttle valve with a variable speeddrive, a frequency converter. Thepayback period was two years and twomonths and the present value for thetotal life cycle cost of the variablespeed system was 662.566 SEK lower thanfor the throttled system. As aconsequence, Stora Enso Fors is advisedto invest in a frequency converter forregulation of the system.The general conclusion is that a focuson system efficiency is the mostimportant factor in energy efficiencyprojects and that the system regulationmethod has a large impact on the overallsystem losses and hence its efficiency.Energy efficiency potential forthrottled systems with centrifugal pumpsis large and significant economicalsavings can be made through investmentswith short payback time..
En studie i riskhantering : Hur börsnoterade bolag redovisar intern och extern risk
Abstract Over the years the consciousness of risk has grown. It?s hard to influence risks, therefore there are guidelines stating that significant risk must be included in the annual report. This paper is a case study; the purpose was to examine how four Swedish listed companies chose to disclose their internal and external risks. Risk is initially described in general sense and then it figures to what constitutes an economic risk.Through a case study of four Swedish listed companies? annual reports we have, through qualitative methods found how the companies chose to disclosure their risks.

Politiskt deltagande hos Kanistammen i Kerala: en fallstudie
This study is case study of political participation among the Kani tribe from Kuttichal grama panchayat in the Thiruvananthapuram district in Kerala, India. The study is based on the collected data of 117 people of the Kani tribe living in four different settlements: Pankavu, Mangode-Valippara, Chonampara and Kaithode. The aim of the study is to examine the impact on political participation by different factors, which is done by the use of the quantitative method of cross tables. The study confirms previous studies in its conclusion that high status individuals, defined in terms of education and economic standard, are the group of the highest political participation, when this is defined as being involved in political work and holding a party membership. On the local political scene however, where political participation consists of participation in local assemblies and voluntary work, the impact of the examined variables are very limited.
Föräldraledighetslagen som diskrimineringslag
The concept of sustainable development has been pervasive in recent years and many organizations choose to implement sustainability and adapt their activities accordingly. The purpose of this study have been to explore how a collaboration on the use of waste materials may look to analyze what influences cooperation. A case study has been carried out examining a Swedish state regional project aimed at creating partnerships between actors and utilizing textile waste with the help of design. The study was conducted using qualitative methods and the collection of data has been done through interviews and by examining documents. The results show that there are seven key factors that affect cooperation: expectations, commitment, internal communication, a strong non-profit actor, individual treatment, personal networks and the diversity of actors.
Vilka faktorer påverkar beslut om förtida projektavslut? : En fallstudie av utvecklingsprojekt hos svenska industriföretag
Today many industrial companies invest a lot of resources on research and development to resist the tough competition on the global market. This leads to a high risk game when the companies start many development projects, with uncertain outcome where some of the projects have to be terminated prematurely. The main purpose with this study is to identify factors, both internal and external, that influence the decision to terminate projects prematurely in Swedish development projects. Factors mentioned in the literature will be compared with case studies on three Swedish industrial companies to demonstrate the most important ones when taking such decisions. First a literature study was made to identify basic terms, a general project model and factors affecting the decision.
Regional Styrningsproblematik i ett Utvidgat Europa - en komparativ fallstudie av Frankrike och Polen
The aim of this comparative study is to analyse the French and the Polish regional governance in order to see if there are any differences in their regional ruling systems. Further more I will study their different possibilities in taking part in the European Union regional political market. The shape of the regional systems will be explored both organisationally (study of the institutional entities of the regional construction) and functionally (study of the competencies of the regional body etcetera) to focus on its cause on the regional development. My over all focus will be to find out whether regional rule means differently in the countries France and Poland.Several questions are dealt with and the two main ones are as follows; How do the different structures of the form of government in France and Poland influence the governance on the regional level? Do Poland, as a new member state of the European Union, have what it takes to face the challenges of the new membership; or are there a complex of problems arising from the admittance that prevent its regions from fully taking part in the European regional political market?Some of my conclusions are as follows;There are major differences between the two countries when it comes to their regional ruling systems leading to different abilities in taking part in the European regional political market.
Prissättning av fastighetsförmedling: en fallstudie av tre fastighetsmäklare
The aim of this thesis is to get an idea of how service companies set their prices. The method used was a case study approach, which was conducted at three real estate companies. The study showed that when setting their prices, the main aspect is their own costs. However, we have found that several other aspects play a big role when setting prices on services in real estate business such as individual customer behaviour and market competition. We have also found that the real estate companies charge very similar prices.

Alla ska med? : en jämförande ideologianalys av medborgarskapsbegreppet i dansk och svensk parlamentarisk debatt
Citizenship is fundamental for participation in a democracy. It gives us rights but also responsibilities in the state that we are citizens of. Citizenship provides us with the opportunity to vote in order to influence who should govern us. However, not all living in a state are citizens. Some individuals are not included in the political life of the state.In recent years, there has been a rise of nationalist political parties in Europe.
Förluster av nedströmsvandrande fisk vid turbinpassage : En fallstudie för att främja den småskaliga, såsom storskaliga vattenkraften
The expansion of the Swedish hydro power has contributed positively to the reduction of the environmental impacts from the fossil fueled power production. In the same time the extensive expansion has been proved to cause negative ecological and local environment impacts of a stream. This, in turn, has been affecting the biodiversity and fish stock negatively, which has been reduced. One of the underlying problems is the lack of possibility for the fish to pass the plants, but it is also directly correlated to the mortality rate of the fish passing through the turbine, which this study is investigating.The mortality rate has been computed for three different locations in Sweden, Untra, Tännfallet and a third one whose location is confidential, and is denoted as Case 1, 2 and 3. The model used to calculate the mortality rate in this investigation is based by existing blade strike models and knowledge and are investigating the death due to mechanical injuries from collision with a runner blade in the turbine.
Dragkampen mellan svenska och kinesiska hitech-företag : En studie av två internationella mästarföretag inom telekombranschen
The aim of the study is on basis of Peters and Waterman?s factor of success, to examine the successful companies, Ericsson and Huawei, and to analyze the R&D and positioning strategies of the companies.To accomplish the study we have used a case study using interviews and annual reports to collect data. Three persons have been interviewed, two from Ericsson and one from Huawei. All annual reports from the year 2004 until 2011 have been reviewed.Our finding is that Ericsson and Huawei do not, according to Peters and Waterman?s model, fulfill all factors of success and their R&D strategy varies depending on the situation and which knowledge the company already possesses and needs.

Spermaadhesiner i olika fraktioner av hingstsperma :
Breeding-induced endometritis in horses seems to be down-regulated by certain components in the seminal plasma. These components are most likely some of the proteins in the seminal plasma in the stallion ejaculate, the so-called spermadhesins. This study aimed to recognize these proteins and determine their quantities in different fractions of the ejaculate. Fractionated ejaculates from four stallions were used to determine the presence and amount of proteins by way of size-excluding chromatography. All former known proteins, except two, were recognized in this study.
?Education is for life, not just for school? : En jämförande studie om läs- och skrivutveckling i Gambia och Sverige
This report describes a comparative study about reading- and writing development in ?A-towns school? in The Gambia and in ?Villaskolan? in Sweden.The purpose of this study is to compare two teachers in Sweden with two teachers and two volunteers from the school in Gambia, with focus on their thoughts and methods on teaching reading and writing at each school and in their social context. The aim is also to observe and describe how classroom environment at both schools can encourage students to read and write.The theoretical base of this study is rooted in a sociocultural perspective but I have also chosen to illuminate behaviorism and cognitivism. The study is qualitative and the main research methods are interviews and observations of the classrooms.My conclusions are, even though considerable differences in approach and conditions, teachers in both schools work hard and show dedication towards their students.Another finding is that teachers use different techniques and working methods to achieve the same goal -to teach their students to read and write based on what is required of them in their cultural and social context. The different ways of teaching have been caused by the existence of different perceived needs based on culture and tradition.One conclusion is also that read and write requirements for students in the Gambia and Sweden are different from each other.
