The purpose of this study was to investigate how high school students felt that the computer helped or hindered participation and self-esteem in the learning situation and if the students experienced any differences between when they had been relatively alone in using a computer compared to when everyone had their own computer. The starting point was the national one-to-one projects made to give every student access to a personal computer and how it affected students in special educational needs and previous research. The theoretical approach was based on socioculture/activity theory and theories of self-esteem. Ten high school students in grade one at a senior high school that previously had started up a one-to-one project was interviewed. The results showed that the students primarily used the computer to write and to search the Internet, but even as a alternative or compensatory tool.

It is important for every store to have a good financial performance which can be affected by the average purchase and the number of customers in the store. Customers shopping experience can affect both of these factors and therefore it is important for retailers to know about how an in-store environment can affect this experience. The purpose of this study is to give retailers an indication of the importance of consumers' shopping experience and how this may affect the store's financial performance. To study this subject an in-store survey was conducted in four grocery stores in Stockholm where a total of 320 consumers answered a total of 41 questions about their shopping experience. By sales data it was possible to conduct a statistical analysis to see which variables regarding consumers shopping experience influenced the average purchase.

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.

The voltage regulation in Fortum Distributions medium voltage network in Stockholm does not work satisfactory. This results in too high distribution voltages with many customer complaints as a consequence. The reason is the model responsible for compensating for voltage drops in the distribution network. Despite several adjustments Fortum has not been able to find the source of the high voltages and has therefore appointed an investigation in the form of a thesis work.The aim of this investigation is to locate the error and to produce a proposal regarding the solution of this error using the existing system, common industrial knowledge, state of the art research and the option to use voltage readings from the different substations.The conclusion of this master thesis is that the largest contribution to the high voltage levels is made by the large compensation for distribution loses. Furthermore an additional error in the model has been found.

Since the brain is an important prerequisite for human language there is a great interest to gain more knowledge about healthy brain activity during language mediated communication. This study examines variations in high level language ability relating to demographic factors like gender and age and relates language ability to neural activity.Eighteen individuals in ages between 22 and 64 were included and divided into groups in relation to gender and age. The material used to assess language ability was derived from Testbatteri för Bedömning av Subtila Språkstörningar (Laakso, Brunnegård, Hartelius & Ahlsén, 2000), Swedish Lexical Decision Test (Almkvist, Adveen, Henning & Tallberg, 2007) and a reading test (Högskoleprovet). The results were correlated with measured brain activity using functional Magnetic Resonance Imaging (fMRI) and language paradigms. ANOVA was applied to discover possible demographic variances in language ability as well as in brain activity.The results showed no significant differences in language ability.

The purpose of this report was to investigate to which extent local presence of large herbivore mammals (Alces alces, Cervus elaphus, Capreolus capreolus, Dama dama and Sus scrofa) covaries with small rodents (Myodes glaerolus, Apodemus flavicollis and Apodemus sylvaticus? The hypothesis was that high abundance of wild ungulates would inhibit the density of small forest rodents. The data was collected during field work within FoMA (Environmental Monitoring Assessment)/SLU (Swedish University of Agricultural Science). The Ungulate dropping inventory and rodent trappings, which is the base in this report, where performed 2012 ? 2014 in Gnesta/Nyköping municipalities (G/N) with a relatively high density of wild ungulates and Vetlanda/Växjö municipalities (V/V) with relatively lower wild ungulate density.

The effect of total dietary fat on the blood lipid profile: a reviewFat consumption has increased in Sweden in the 21th century, probably due to the advancement of the diet low car high fat (LCHF). Also, cardiovascular disease is the leading cause of premature death in Sweden. Various blood lipids are used to evaluate the cardiovascular disease risk; total cholesterol, LDL, HDL and triglycerides among others. High levels of total cholesterol, LDL, triglycerides and low levels of HDL are believed to increase the risk. The purpose of this review was to examine the effects of high-fat-diet on blood lipids, cholesterol, LDL, HDL the ratio between LDL/HDL and triglycerides through a systematic review.

The aim was to examine whether measurements of creativity as a domain general trait can explain possible connections between a domain general creative performance and one of the creative domain specific areas, humor. Another aim was to examine whether the maladaptive humor styles can explain possible differences in creative performances. An Internet-based survey was used on 281 students from a Swedish university. The survey was composed of three parts consisting of three separate measuring instruments ? Sense of Humor Questionnaire (SHQ-6) was used to measure the respondents? sense of humor, Humor Style Questionnaire (HSQ) measured the respondents? humor style and Alternate Uses Test (AUT) gave the respondents an opportunity to account for their creative performances.

This report describes the development of a high-voltage connector at the request of Scandinova Systems AB in Uppsala. The development process is described from the making of a customer demand specification, to the making of drawings for the manufacturing of prototypes. Scandinova develops high-voltage modulators, hence the need for connectors that can handle very large power pulses. Their current connector has several weaknesses that may cause the connector to melt or catch fire. The development began with a number of studies that included the modulator structure and the current connector structure and functions.

The Ericsson AXE-based systems are programmed using an internally developed language called Plex-C. Plex-C is normally compiled to execute on an Ericsson internal processor architecture. A transition to standard processors is currently in progress. This makes it interesting to examine if Plex-C can be compiled to execute on the JVM, which would make it processor independent. The purpose of the thesis is to examine if parts of the run-time environment of Plex-C can be translated to Java and if this can be done so that sufficient performance is obtained.

The aim of this thesis was to examine if it is possible to keep nitrogen in the form of nitrate(NO3-) in ponds from one season to another by keeping a high concentration of oxygen in thepond water. This hypothesis was tested by doing a lab experiment where two systems werecompared according to nitrate concentration. One system had high concentration of oxygen inthe water and one had low concentration of oxygen. Before the main experiment wasconducted I did a pilot study to test the system setup and included parameters. The result fromthis study and the main study did not show the same result.

Under 1990-talet kom Kaplan och Norton fram med styrningsfilosofin balanserat styrkort som innebär att managers uppmanas att inte enbart ta hänsyn till finansiella mått utan bör använda sig av både finansiella och icke-finansiella mått för att kunna styra företag. Det här konceptet med balanserat styrkort har sedan det togs fram utvecklas och i början av 2000-talet finns den tredje versionen av balanserat styrkort som tillsammans med avancerad teknologi bildar konceptet business performance management. Det innebär att den information som ligger till grund för de rapporter som består av finansiella och icke-finansiella mått hämtas från en central databas i det verksamhetsöverskridande business performance management systemet. En anledning till det är att business performance management knyter samman balanserat styrkort med avancerad teknologi som möjliggör att managers därmed har möjlighet att få tillgång till en gemensam version av verkligheten, det vill säga en gemensam mental bild hur företaget presterar. Dessutom möjliggör den avancerade teknologin att managers oavsett om beslut tas som är strategiska, taktiska eller operativa att de har tillgång till den information som beslutsunderlagen baseras på i rätt tid.Den information som beslutsunderlagen baseras på måste bestå av en tillfredställande god kvalitet för att möjliggöra att managers tar korrekta och optimala beslut.

Approximately 400 people in Sweden die each year by lung cancer caused by radon gas. Authorities have in recent years invested big resources and organized campaigns to encourage people to take action against high occurrence of radon in residences. With low frequency of applications for radon allowances as the main measure, a lot interprets on a very low commitment. The purpose of this thesis is to investigate the reasons for the low commitment among people. The study is based on a questionnaire survey sent to 444 house owners in Uppsala.

When the independent upper secondary schools were started in 1992, it meant a change in the competitive relationship for the local upper secondary schools. A reduced number of students during some years ahead, while the number of independent upper secondary schools increase will probably result in tougher competition between upper secondary schools.The purpose of this study is to review and compare financial and performance management between a public and an independent upper secondary school. The dissertation will focus on the now existing competitive relationship between the two types of upper secondary schools.The theory underlying the study is Porter's model - five competitive forces. The model is applied to the local upper secondary school and used to identify competitive factors affecting upper secondary schools. The study is using a qualitative approach with five interviews at two upper secondary schools, one independent and one public, located in the same town.The comparison of financial and operational management of upper secondary schools indicate that the differences are not as great as we first imagined, but that there still are some differences.
