Today there are many applications of digital terrain models (DTM) and the requirements of low uncertainty increases. Most of the DTM are produced with Global Navigation Satellite System (GNSS), terrestrial laser scanning (TLS), airborne laser scanning (ALS) and total stations. Guidelines for the preparation and verification of DTM are found in Swedish Standards Institute ? Technical Specifications (SIS-TS) 21144:2007 and SIS-TS 21145:2007. These were defined in collaboration between Swedish National Rail Administration, Banverket, and Swedish Road Administration, Vägverket, to satisfy the needs of requirement formulations in the production of DTM planning, design and construction. The purpose of this paper is to produce and control DTM over Åkermans kulle, located west of the University of Gävle, according to SIS TS 21144:2007 using GNSS with network-RTK, TLS and ALS.

The survey aims to problematize masculinity in the exhibitions of the museum.  In what way is masculinity interpreted and valued in exhibitions? What is the attitude towards masculinity in gender oriented museological texts? This study investigates in which way masculinity is written about ? how interpretations of masculinity emerge in the texts and what consequences this may have.The survey is based on the method of discourse analysis and the material is processed from a gender perspective. The source material consists of museological texts dealing with the topic of gender and museology, which also is the core material. A complement to this is a selection of exhibition catalogs from museums as well as reviews which are also based on art exhibitions. The main point of the source material consists of the museological texts.The survey highlights that the gender-conscious museological discourse understands, interpret and evaluate masculinity on a more or less given regulatory framework.

Swedish sawmills of today suffer from unsatisfying economy with high costs and low benefits. The economical result depends on how well the sawmill can use their raw material. Iggesund Timber AB, a sawmill in the Holmen group, produces a large amount is enduse orientated products for the woodworking industry. Therefore the aim of this student thesis was to investigate the possibility of automatic enduse orientated quality grading of Scots Pine (Pinus sylvestris) saw logs by using a gamma-ray log scanner. Iggesund Timber AB has the possibility to grade logs automatically with TINA, a two way gamma-ray log scanner. Grading and classification of Scots Pine logs in Sweden today are mainly manual but can in some rare cases be automatic.

The purpose of this master's thesis is to examine how a Swedish public library's collection of books on African history looks like, who the writers are and how Africa and its history areportrayed. The focus of the analysis is on the front and back covers and in some cases on theinformation texts inside the books. The chosen library is the city library of Umeå. The 15books examined were found on the shelf classified as Kp ? the classification for African history according to the Swedish SAB-classification system.

The purpose of this study was to examine and compare what six preschool teachers thought about their opportunities to take advantage of children's interest in natural sciences and technology, across four kindergartens. The following questions were explored in order to achieve the aim of the study: How do the preschool teachers interviewed describe their work with science and technology in the preschool and what these preschool teachers think about the meaning of motivation in the children?s learning of natural sciences and technology in preschool.  The study used a qualitative approach in the form of semi-structured interviews and interviewed a total of six trained pre-school teachers from four kindergartens with different profiles. The first kindergarten focuses on mathematics, science and technology.

Title: I saw it on Facebook ? Youth presentation of self on FacebookAuthors: Nicole Dreher & Anders SkoglundPresented: 01.06.2010Purpose: The purpose of this thesis was to examine how the, in the study, participating youths make their presentation of self on their Facebook profiles.Methodology: The method used in the thesis was a social semiotic analysis focusing on the social semiotic concepts: semiotic resource, semiotic potential, affordance, denotation and connotation. A social semiotic analysis of composition was also used with the purpose to gain a deeper knowledge of the social semiotic affordances of Facebook?s composition.Theoretical perspectives: The theoretical base of this thesis consists mainly of Erving Goffman?s theory on presentation of self in everyday life as well as relevant theories to youth culture in sociology and identity in social psychology.Conclusions: The results show that the youth?s presentations of selves mostly takes place in their profile picture, status updates, groups, fan pages and through their communication with other users on their wall. The borders between front and back stage on Facebook entirely depends on the norms that the reader expects the profile owner to uphold.

Sewer trenches usually contain material with a higher hydraulic conductivity then the adjacent soil. Thus they can serve as paths of preferential flow in a polluted area. Wastewater from factories can also leak from wastewater pipes and pollute the soil in the sewer trenches.The purpose of this project was to investigate pollutions in sewer trenches and in sewer pipes in the industrial area of Köpmanholmen, 20 km south of Örnsköldsvik in the north of Sweden. To make an estimation concerning the potential of transport of pollutions in sewer trenches, hydrological calculations were performed.Leakage to any greater extent did not seem to be a problem in the area. This is the case both for the concrete and the wooden pipes that have served as factory wastewater pipes.

An inquiring study of literature has been conducted, about the human colour perception (theimpression of colours). The colour has been examined, both as conscious and subconscious signal,and reasons for it?s influence have been exammed.The practical parts of the degree project have been carried out in active collaboration with thecustomer, The Association Hedemora Assistansservice (HASS), which offers handicapped persons astimulating spare time by personal assistance. A graphical profile-programme and an informationfolderhave been produced, easy received by both handicapped (with defective vision) and normallysighted persons. The graphical profile-programme was made in collaboration with the customer.Concerning the information-folder HASS took the main responsibility for the choice of photographswhile layout, text writing, colour-reproduction, original-production and connecting printing workswere made independently.

In 2008 the National Library of Sweden decided to give upClassification system for Swedish libraries and start using DDC(Dewey Decimal Classification) from January 1 2011. Thisdecision has influenced the whole Swedish library system and longbefore the National Library of Sweden took this decision thequestion had been thoroughly discussed and debated in Librariancircles.The aim of this thesis is to find out which arguments have beenintroduced in the debate, if the discussion has changed from beforethe decision to go over to DDC was taken to after wards, and if sohow it has changed. My thesis will discuss the following threequestions:? Which arguments were brought forward in the debate,both for and against a transition?? How has the debate about the Swedish libraries?transition from Classification system for Swedishlibraries to DDC changed from before the decision ofthe Royal Library was taken to after?? What conclusions can you draw from the debatewhich has been led about the transition to DDC?The empirical material consists of six articles dealing with thetransition to DDC and in the analysis of this material I have used atext analyses, analysis of. The analysis shows that more or less thesame arguments for and against have been used in practically allthe articles, and the debate has not changed very much.

The depth-to-water-index (DTW-index) is derived from digital elevation models (DEM) to map soil wetness, in terms of distance from soil surface to the ground water table. The aim of this GIS based study was to investigate the existence of a relationship between DTW-index and forest site productivity (SP). The belief of such an assumed relationship was based on knowledge that the ground water level is related to site properties that can either promote or impede tree growth. Data primarily comprised rasters of the Krycklan catchment in northern Sweden and depicted DTW-index and a laser scanned vegetation height. The 100th height percentile of each pixel in the vegetation raster was assumed to mirror the top-height, letting it act as a relative measure of SP within a delineated area of equal stand age.

Social media has meant that organizations can engage in dialogue with their audience without journalistic intermediaries. PR 2.0 is a term that defines the new way for organizations to work with public relations in the new media landscape. The aim of our study is to examine how IKEA uses social media to create, maintain and develop their relationships. Furthermore, great interest is directed to the concept profile. This essay will examine how the stated profile IKEA has pervades the work on social media.

I det här arbetet undersöks fältdiagnostiska metoder och användbarheten av dess resultat i planeringsstadiet av en ny trädgårdsblåbärsodling. Syftet är att fastställa vilken information som kan erhållas från en jordanalys, penetrometerundersökning och en jordmånsbeskrivning samt vilka rekommendationer från dessa undersökningar som vidare kan härledas till planeringen av en ny trädgårdsblåbärsodling. Som exempel och fallstudie används en bit åkermark i Ockelbo där provmätningarna ägde rum.Resultatet visar att fältundersökningar i kombination med en jordanalys gjord på laboratorium är ett bra verktyg för att utreda en jords grundläggande förutsättningar. Jordanalysen visar hur näringsinnehållet ser ut i jorden samt vilka eventuella näringsbrister eller näringsöverskott som finns. Penetrometerundersökningen informerar om eventuella markpackningar, som utgör eventuella hinder för t.ex.

Our purpose was to investigate when a specific phenomenon is taken out of context and used in a manner not originally intended for. Facebook is meant to be used in the private sphere as a way for individuals to communicate and keep in touch with family, friends and acquaintances. However, Facebook has begun to be used increasingly in the professional context like recruitment. We have through qualitative interviews explored how the respondents, professional recruiters and future job applicants, think about the use of Facebook in a recruitment process. By applying theories dealing with roles and lifestyles we have been able to pinpoint our empirical data.

Sahlgrenska Academy at University of Gothenburg Department of Internal Medicine and Clinical NutritionAbstractTitle: Can probiotics prevent atopic dermatitis in children with high risk?Author: Laura Pienihäkkinen and Max OlinSupervisor: Heléne Bertéus ForslundExaminer: Anna WinkvistProgramme: Dietician study programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: May 22, 2012Background Allergic disease is today common, this including atopic dermatitis, which is the most common inflammatory skin disease in the world. Heredity has been shown to play a major role in the development of this disease. It is therefore of high interest for both the individual and society to find effective methods for preventing atopic dermatitis in individuals with high risk profile. Probiotics are beneficial for the bacterial profile in the intestine and it is therefore of interest to study if they through their anti-inflammatory effect could prevent atopic dermatitis.Objective The aim was to study whether administration of probiotics to the mother and the child (directly or via breast milk) could prevent atopic dermatitis in children with high risk profile (at least one first degree relative with a diagnosed allergic disease).Search strategy A systematic literature search was done in databases PubMed and Scopus with search terms maternal, prenatal, probiotics, allergy, atopic dermatitis, prevention, and children.Selection criteria Randomized, controlled human studies and original articles in English were included.

This thesis aims to investigate if peer-groups based on industry classification perform as well as, or better than, peer-groups based on other measures that represent factors affecting the price-to-earnings multiple. In contrast with previous empirical studies, a solid theoretical approach is used in defining which factors, according to valuation theory, affect the P/E-ratio. The factors identified as explanatory are accounting measures, risk and growth. Furthermore, we have recognized several measures that represent these factors. These measures are tested for accuracy of prediction in terms of the P/E-ratio for peer-groups based on these measures relative to an industry classified peer-group.
