The aim of this thesis is to answer whether a group of databases dedicated to selling books or a group of databases dedicated to lending books is more efficient. The measurements used to determine the efficiency of the two kinds of databases are Cumulated Gain and precision in modified versions. The inquiry has been conducted thus that the same 18 queries have been put forth to six databases and these results have consequently been judged according to relevance on a 4-graded scale by five respondents. The rankinglevels have then been merged to one average value per respondent and ranking. These values have then been used to determine CG/iCG/nCG and P@n per query, rank 1-10, per database and per group (the groups being STORE (BUTIK) and LIBRARY (BIBLIOTEK).

Wheat yield depends on the number of ears per m2, the number of kernels per ear and the kernel weight. By knowing the ability of different cultivars to compensate for the different yield components and knowing which yield component that is the most important for the final yield, the farmer can match the cultivar and management to the location. The objective of the study was to investigate how the yield components of winter wheat vary depending on genotype, environment, sowing density and date of sowing.Seven varieties were grown in four locations in Sweden with three different sowing densities and with an early and a late sowing date. On each experimental site, the surviving plants after winter were counted, as well as the number of shoots at early and late spring and the number of ears. Ten ears from each site were cut at three different occasions, starting from the time of blooming, with 200 day degrees between each cut.

Holmen Skog has in some places in their operation area access to timber trucks with centre mounted scrapers. They make transportation more flexible and reduce reliance on contractors for road maintenance. The trucks with centre mounted scrapers have a higher tare weight, making them less productive and therefore they receive compensation with a 0.75 % increase on transportation price. The purpose of this study was to investigate what actions a timber truck with centre mounted scraper can perform with acceptable quality in winter, and to examine if it is an economically profitable solution for the truck operator and charterer. The study was done in three stages; interviews, performance analysis of the transportations carried out and an economic analysis with the help of Sven Erik Gilles spreadsheet tool. The study included the districts Delsbo and Hudiksvall.

The giant otter (Pteronura brasiliensis) is listed as an endangered species and scientific litterature concerning its biology and behaviour is scarce. The current study observed a group of three giant otters in a Swedish zoo. First the otters normal behaviour was recorded. Then the aim of the study was to see if the otters behaviour changed when given blue mussels (Mytilus edulis). Furthermore the aim was to see if the otters displayed any tool-using behaviour when given mussels.

Male piglets have been castrated for centuries to avoid contamination of their meat with boar taint, a strongly unpleasant odour that makes the meat inedible. Today boar taint can be prohib-ited by vaccination against gonadotropin releasing hormone (GnRH) using Improvac®. The aim of this study was to evaluate the efficiency of vaccination on growth performance and behaviour of vaccinated male pigs compared to surgically castrated male pigs. The effect of two feeding regimes, restricted (SLU-norm) and semi ad libitum, was also included in the study. At birth, pigs (n=206) were randomly allocated to the two treatment groups; surgically castrated and vaccination.

Mergers between companies has become more and more common in Sweden and in the rest of the world with the motive to increase the competitive strength in the current markets and has an important role within organisational development of companies. When organisations merger there is not only buildings and objects that are put together but also their individual organisational structures, people, values and cultures. This can be a difficult process and can affect many people in how they think conscious as well as unconscious, feel and react.The purpose of this thesis is to gain a deeper understanding of how employees are affected following a merger when changes in the organisational culture come up, and how these changes are expressed.This thesis is delimited to investigate only one company, Skruf Snus AB and only focus on their business and employees in the region of Stockholm. The thesis contains a qualitative investigation with semi structured interviews that has been carried out with eight employees at Skruf Snus AB. The thesis is partly based on a model of Schein which describes the different levels in organisational culture and partly on some theories about reactions to change in relation to the integration between the employees following a merger.The results of the investigation indicate that with a merger the whole organisational culture is affected and therefore also the employees.

Ternary codes for unequal error protection is a part of a communication system where different parts of the information to be transmitted can receive different amount of error protection. There are a lot of applications where the channel conditions fluctuate so that reliable or acceptable communication can not be guaranteed. Regardless whether the fluctuations of the channel are intentional or not the idea is to let the coderate decrease so that the error correcting capability can increase for the part of the information to be more protected. By using the support, the nonzero positions of the ternary code, a new binary code can be extracted with properties different from the ternary code in the sense of cardinality and minimum Hamming distance. When the channel conditions are good the receiver decodes the message using ternary decisions and receives all information included in the codeword.

The purpose of this study was to gain deeper knowledge about the special needs of guidance significance as an aid to students based on teachers' views and perceptions.Eight teachers from three different municipalities, active in primary school and middle school have been interviewed since all have participated in and have experience with special needs tutoring. Their responses were compiled and answered the three research questions: What experiences have teachers of special education counseling? How do teachers the guidance they received from a special teacher? What effect has the special educational guidance given for the inclusive education? The result shows that the special educational tutorial helps teachers gain a deeper understanding of students in need of special support and guidance to the mission vary in scope and content. The special educational tutorial that is aimed directly at the teachers seem to have a positive effect on inclusion and a critical/dilemma perspective while the consultative guidance primarily directed towards the adaptation of educational material and allows students to walk out of the classroom to receive special education promotes exclusion and ability grouping and a compensatory perspectives. From a sociocultural perspective pointing results of the study that teachers with special education tutoring experience to students in an inclusive education contribute to each other's learning,creating meaningful for everyone involved..

The aim of this research review is to map research about how children relate to nonfiction, and how adults, represented by parents, librarians and teachers, relate to children?s nonfiction and its possible purposes, and also the similarities and differences between them, according to current research.A theory of three different ways to look at reading is applied to the material concerning adults? views of children?s nonfiction. To show children?s views, themes are extracted from the research material, using an analysis model of four different ways to read.Studies show that most children as well as adults perceive children?s nonfiction in a traditional way as a means to gain knowledge and facts, and primarily related to school work.Nonfiction can also help children with reading difficulties to practise reading, by stimulating their interests. Many children read nonfiction because they prefer to read ?real stories? about actual people and events.

This thesis is a part of the project "Sustainable harvesting and storage of sugar beets, more sugar to practice". The work has included a large part of practical experimental work with weight measurement, graduation and storage planning. The aim of the project is to be able to see whether the cultivars react differently in different storage conditions. The project has included storage under controlled conditions to give as accurate results as possible. To be able to mimic the farmers own preconditions the samples was harvested with a conventional Holmer.This project has two parts, one concerning the nature, time and temperature on storage where a number of different cultivars where investigated during three different recording times, two different temperatures and controlled in a controlled environment.

The aim with the thesis is to get deeper knowledge in one of the subjects botany, livestock technology or economy. I have chosen to get deeper knowledge in how to store potatoes. How are you going to act to keep the quality on the potato during the storage, with a minimum of weight lost? My aim with this thesis is to get a view over how the potato act in storage space. The storage environment is very important in the storage space.

As consumers we want to know from whom we buy, what we buy and the impact the company has on our planet. In recent years there been an increasing number of scandals concerning child labour, dangerous chemicals and falsely labelled meat. A good way for companies to communicate their environmental efforts is to establish a sustainability report, where they describe their work and their impact on our environment. By concentrating on H&M?s sustainability report, as well as conducting a rhetorical analysis, we have been able to focus on the following research questions:  ? Why do companies establish CSR reports? ? How do companies gain legitimacy through their rhetorical choices? ? How do companies try to influence recipients? attitudes to the company? We begin by studying the context, which is of importance when using a rhetorical method and thereby attempt to understand in what situation the text is created.

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.

Purpose:The purpose of this thesis is: to determine key success factors for an organisation?s internal process of internalising future trends forecasting. Methodology:A qualitative approach has been chosen by examining three different companies (Electrolux, H&M and, Sony Ericsson) through interviews and other data. The empirical material have been analysed by using valid theory as a platform from where the analysis can be performed. This has created a conceptual analysis that enables the use of the conclusions in other similar companies.
