Nanofiltration is a proper way of preparation of drinking water. The process has a lot in common with reverse osmosis where a semipermeable membrane is used to separate a pure water flow from the remaining water. A pilot plant was used to ensure that nanofiltration is a suitable technology for a specific waterworks station in Glemmingebro, Ystad. The purpose was also to find out if a pH-adjustment is needed for feed water in a possible full scale plant.  In this case nanofiltration is used mainly to remove sulphate and calcium since the raw water contains concentrations of these substances which exceed the limits for potable water. It is important to receive a high recovery (RC), otherwise the deliviery of water won?t be high enough.

This paper aims to analyze the legal functions and characteristics of bills of lading in their basic form to examine the legal framework for the adoption of electronic bills of lading under Swedish law. With a comparative analysis against English law, particular attention is given to the 'document of title' function. This has been claimed to pose challenges in the transition to electronic bills of lading. While Swedish law presents potential parallels, critical aspects like negotiability and indirect possession require resolution. It analyzes international regulations such as the Rotterdam Rules and Model Law, addressing challenges and potential solutions for digitalization.

The purpose of this study is to research whether or not gender has an impact on assessments regarding the support for persons with special nedds (LSS personkrets 3). Administrators working in disability care are to make decisions on the basis of the individual's needs when assessing the need for aid and support. This study is based on qualitative interviews, with six administrators, and one head of operations. The empirical data collected has been thoroughly analysed from a gender perspective, rooted in Butler's theory regarding performativity and subversive actions, as well as Connell's gender regime, and Hirdman's gender contracts. Results show that administrators have ackknowledged and noticed differences in how male and female users express their needs, where the difference lies in the communication; females seem more reserved and shy, whereas males seem more outward and extroverted.

The aim of this thesis is to examine how salesperson control can be exercised in a retail store environment. A case study has been performed on a Swedish fashion company emphasizing the relationship between the company?s upper level management and their retail store operations in order to describe, analyze and classify the prevailing management control mechanisms. The paper presents an agency theoretical approach to the relationship applying behavior- and outcome based control theory, performance measurement theory and incentives theory in order to give a comprehensive image of the control system. The main finding is that the company?s management control system as applied to the sales force in its retail stores can be categorized as mainly behavior-based despite several explicit outcome-based features..

Biogas is a renewable energy source that is produced by anaerobic digestion of organic mate-rial. In Sweden, biogas predominately comes from sewage water sludge and landfills or from organic waste of households and industries. Small scale digestion plants at farms are espe-cially expected to contribute to increased biogas production in the future. Biogas can be ob-tained directly in it?s raw form and used as fuel in a combustion chamber.

With an IT outsourcing project there are many factors affecting how efficiency andquality develop in the outsourced activity. The Purpose of this study is to identifythese factors through a case study in a global company that is dissatisfied with theefficiency and quality of their outsourced helpdesk. For data collection methodsinterviews and observations were used. Interviews were conducted with people fromdifferent parts of the company in three different countries, all somehow involved inthe outsourced system. The observations were made with the outsourced company tosee how the employees work and fill information gaps that the interviews could notcover.

The school inspectorate surveys illustrates problems and difficulties for teachers to suit individualized instruction. Therefore, the purpose of the study to investigate whether and in what ways some pedagogues experiences and practice offers the individualized instruction that the governing documents require. The study is based on a qualitative method in the form of semi-structured interviews and observations with four experienced pedagogues. I have been using Piaget's theory of the concrete material's importance for learning and also Vygotsky's theory of the proximal development zone. The results showed that pedagogues understand the importance of individualized instruction.

This Masters thesis aims to study the reading habits of readers of romantic fiction, especially focusing on gender issues. The main areas studied are the function of reading romances compared with reading other genres, and how the readers value romantic and general literature. The thesis is based on qualitative interviews with seven readers of romances, five women and two men. The theoretical background is based on reader response theory and gender theory. Before I started interview the readers I asked them to read two romances; Sidney Sheldons - The best Laid Plans, and Rosamunde Pilchers - The End of Summer, which we later discussed during the interviews.

Based on the concept of rhetorical situation, the purpose of this study is to compare and describe the three Socialist leader's May Day speech from the years 1954, 1978 and 2011. The results of the analysis showed that there is a big difference in how the leaders chooses to appeal to the rhetorical audience. Erlander, 1954, never appealed directly to his audience which Palme, 1978, did both initially as repeatedly throughout his speech. Juholt, 2011, has a personal and frequent appeal which is repeated throughout his speech, which is interpreted as a sign of the intimization of the public language. It proved difficult to discuss the Socialist rhetoric as one unified form.

Camera surveillance can provide good protection against certain types of crime, but it can also invade our privacy. The County Administrative Board monitors compliance with the rules by visiting those places to which the general public has access. They have to issue permits before general camera surveillance to those places which the general public has access. In certain cases, in stores for example, general camera surveillance is permitted only if the Country Administrative Board is notified in advance. The Data Inspection Board is a public authority and responsible for the camera surveillance for those places to which the public not has access.

Through this thesis I aimed to further investigate how we can adapt our western and modern views of masculinity and femininity in an ancient population, here on the Pitted Ware population from Ajvide on Gotland. A questionnaire survey was used to compile the modern view of masculinity and femininity. This modern view was then compared with patterns which had become visible through statistical processing of the burial gifts found on Ajvide. The thesis is mainly focused around the concept of gender, but age and status have also been discussed. Through several performed correspondence analysis, it became clear that the current view of male and female differed from the one that became visible in the archaeological record.

The academic underachievement of looked after children is well known. By involving foster carers in a Paired Reading intervention a Swedish project tried to address this issue, replicating a successful British trial. The aim of my thesis was to study the variations in the foster carers? experiences of this literacy intervention. Reading reports from 100 children were collected and qualitative interviews with 15 foster parents were analyzed using concepts from motivational psychology.

The purpose of this study is to explore and understand the social and structural dynamics of an organization working with questions regarding development. The organization in question is Vi-agroforestry, a Swedish based NGO that works around the lake Victoria basin and the focus will be on their office in Rwanda. I have used a qualitative approach and conducted participatory observation as well as semi-structured interviews to gather data. I have emanated from the individuals in the organization by using a theory of microsociological organisationperspecive to understand how the employees create and is created by the existing social structures. (Blomberg, 2003) Even though the office in Rwanda only is a relatively small part of Vi-agroforestry?s operations it is still highly individual and independent from the rest of the organization.

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).
