The questionnaires show that the catalogue still reaches out with most information despiteconstant increase of information search at the Internet. The students seem to prefer University ofKristianstad´s catalogue front.The competition analysis is based on telephone interviews and information material sent from theother universities.
Water balance and nitrate leaching from arable land in a changed climate : a model study
This thesis aims to present the essential background on how to perform climate changeimpact assessments, and to present the results from a climate impact assessment on waterbalance and nitrate leaching for an arable Swedish soil. The soil is a sandy soil in southwesternSweden, grown with spring cereals. This study is meant to be a benchmark example,and cannot be seen as a regional or national assessment for Sweden, rather as an approachto present and analyze the most important parts of these kinds of assessments.A dynamical simulation model (COUP, Jansson and Karlberg, 2004) was used for thisstudy. The model was parameterized and calibrated against data from an experimental site,located in Mellby in Hallands county, south western Sweden. Measurements were carriedout between 1st of April 1988 and 1st of April 1991.
Societetsparken i Norrtälje : nulägesanalys och utvecklingsförslag
The short term effect of phosphorus in sewage sludge was investigated to establish howmuch of this a farmer can grant him- or herself, if using sewage sludge as a phosphorusfertilizer. Possible differences in plant availability between sludge phosphorus precipitatedby iron, aluminum or calcium integrations were studied in a sandy soil at two pH levels.The sludges were analyzed using pot and incubation trials. As the intention was to investigategrowth limitation due to phosphorus deficiency, a soil with low phosphorus supplywas chosen as well as a low phosphorus application rate. Sludge corresponding to 12kg phosphorus per hectare was applied. Treatments fertilized by sludge were compared totreatments where 0, 6 and 12 kg phosphorus per hectare from mineral fertilizer was applied.Every treatment was replicated six times.
Helicobacter spp. i digestionskanalen hos svenska katter : en metodologisk och klinisk studie
Following the accident at the nuclear power plant in Chernobyl in 1986, great volumes of137Cs were distributed over large parts of the former Soviet Union and Europe. Over Scotland,radiocaesium was deposited as wet deposition. Due to the relatively long physical half-life of30 years, there are still measurable activity concentrations in the natural environment. Thisstudy was made on two organic soils, Knockandy Hill and Rora Moss, situated in the easternpart of the central highlands of Scotland. At these two sites, studies on migration and transferbetween soil and plants were conducted.
Utvärdering av metoder för framställning och kontroll av digitala terrängmodeller
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.
Elektriskt system för detektion vid ballistiskt prov
The purpose of this thesis was to design an electrical system for use in a ballistic test at the Swedish National laboratory of forensic science (SKL). The detector unit would use four main parts: coilsystem, transmitter, reciever and indicator. The coilsystem would be based on a balanced system using three coils. One that creates a magneticfield and the other two will sense the differences when a metallobject is in the coilsystem. This report starts out by investigating possible solutions for this specific task followed by a description of the physics that the metaldetector use.
Tar vi barnens intresse för natur och teknik på allvar? : En kvalitativ studie om hur några förskollärare resonerar runt möjligheterna att ta tillvara barnens intresse för naturvetenskap och teknik i förskolan
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.
Renhet och smuts i personarkivet : Ett antropologiskt perspektiv på ordnandet och förtecknandet av personarkiv
Personal archives are a largely neglected subject in archival theory. Among the consequences of this is the absenceof any general established or formalized practices when it comes to arrangement and description. Thisstudy opposes the notion that an archival institution without formal systems of arrangement and description doesnot order and describe archives in accordance with a general conceptual framework of a correct order. Supportingitself on the anthropological theory of Mary Douglas on dirt and cleanliness, it studies the implicit notions oforder that can be found in the archival descriptions of the personal archives kept by the Swedish national archives.Several patterns where revealed by the study: among them the primacy of quantity stood out. The vaguesystem of categories based on Martin Grass description model appears only to be employed loyally where quantitiesof the particular categories are such that they constitute complete volumes, which seem to be the cardinaljustifier of categorical division within the archive.
Jag såg det på Facebook : Unga människors självpresentationer på Facebook
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.
Föroreningsspridning via ledningsgravar : en fältstudie på Köpmanholmens industriområde
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.
Färgperception och grafisk profilering av Hedemora Assistansservie
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.
Bakom Ladan : En skiss eller två på en hälsoträdgård på Wij Trädgårdar
AbstractThe research in the interdisciplinary field of natural-human-health-design has in recent decades gainedmomentum and led to new or new-old ways of thinking and acting in terms of planning and design of outdoorenvironments with the aim of health promotion. Concrete concept models and design guides have begun toemerge as a result of this research.The purpose of this work is to use these guides to develop a design proposal for a supposed health garden,with Wij Trädgårdar in Ockelbo as a base. This has been done in the form of a process description. The targetgroup for the design proposal is long-term unemployed and people who have come to Sweden as refugees.Since the specific design recommendations could not be found for the selected target group, the main materialwas general guidelines for health gardens in combination with guidelines for health gardens directed to targetgroups with stress-related problems, which is a broad target group for which there are relatively much currentresearch.The result is a process description of the progression towards a sketch on a health garden, designed for aspecific spot on Wij Trädgårdar, but available for use in other locations, provided adjustments is made to thespecific location. The sketch is supplemented with plant suggestions to different parts of the garden.
Kan markfuktighetskartor användas för att hitta skogsmark med hög bonitet? : ett gis-baserat försök med dtw-index och laserskannad övre höjd
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.
Välkommen in i värmen! : En netnografisk studie över hur IKEA skapar, upprätthåller och utvecklar sina relationer i det digitala medielandskapet
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.
Fältdiagnostik - ett verktyg för hållbar odling : Resultat och tillämpning av fältdiagnostiska metoder i planeringsstadiet av en ny trädgårdsblåbärsodling
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.
