En tesaurus som ledsagare ? En jämförande studie av tre sökstrategiers inverkan på återvinningsresultatet i en bibliografisk databas.
This Master?s thesis is a comparative study of information retrieval results between three distinct search strategies in simulated automatic query expansion in a bibliographic database. Our purpose is to investigate which of the search strategies score the most effective precision and to what extent the same relevant documents are retrieved (overlapped). A thesaurus attached to the database is used to select appropriate descriptors for the baseline query formulations which subsequently are expanded with hierarchical relations. The search strategies are s1: A baseline query with two or three descriptors, s2: The baseline descriptors combined with at least one Narrower Term, s3: The baseline descriptors combined with Narrower Term and at least one Broader Term.
Magnetfält alstrade kring nätstationer i samband med lokaldistribution av elkraft : Magnetic fields generated by electrical substations during distribution of electric power
Abstract: This report covers primarily the work of documenting electromagnetic fields generated by one of the later parts in the electrical power distribution chain: The electrical substation, wherein 10 kV is transformed to 400 V for use by private consumers. Thus it is one of the most widespread and frequently occurring parts in the Swedish power grid and of particular interest, as electrical substations are found everywhere in populated areas, often in close vicinity to people and animals.The report deals with a number of formulated questions and/or hypothesis? stated at the onset of the work undertaken, theory that is relevant for the topics the report covers, the details of the field work undertaken and the following analysis of the readings, which in term provide answers for the questions stated in the beginning. It also covers what is the currently known short term and long term risks associated with electromagnetic fields in the power frequent spectrum and of varying intensity in the vicinity of humans.The analysis also provides recommendations and identifies several points to carefully consider when planning for new installations or replacements of some parts of existing installations.For enhanced reading comprehension there is, aside from sections with pictures and attached explanatory texts and templates, several graphs, one-line diagram and maps of the power grid among the appendixes to the rapport..

KORTSIKTIG PRODUKTIONSPLANERING I MINDRE FJÄRRVÄRMESYSTEM : En studie vid Strängnäs Energi AB
District heating covers around 80 % of the heating demand in apartment buildings and 10 % in single-family homes in Sweden. In the year 2010 the total input of energy to the Swedish district heating grids was about 70 TWh, which corresponds to 11 % of the total energy input to the whole energy system in the country. Through the combined production of heat and power the CHP-plants often reaches an efficiency of 90 % from energy in the fuel to produced heat and power. In order to keep the efficiency high it is important for the owners of the plant to have good knowledge about the plants performance at different operation points. Strängnäs Energi AB initiated this diploma work together with FVB Sverige ab in order to come up with a program for short term planning of the production of heat and power at the company´s CHP-plant.The work consists of three main parts.
Buprenorfin till get : grundläggande farmakokinetik och påverkan på beteende
In this study the opioid buprenorphine was given to 8 clinically healthy goats. The pharmacokinetics and behavioral effects were studied. Injections of buprenorphine, 0.02 mg/kg body weight was given both intramuscularly (i.m.) and intravenously (i.v.) with a cross over design. The results showed a short half-life of the drug in the plasma, 65.9 ± 17.4 min (mean ± SD), after i.v. injection.
Korttidsregleringsmönster i Ångermanälvens avrinningsområde : Har elmarknadens avreglering påverkat regleringsintensiteten?
The effects of the deregulation of the electricity market 1996 in Sweden on Short-term hydropower regulation are unknown. This report investigates patterns in subdaily regulation in the Ångerman River Basin during the period 1993-2011. Differences in subdaily flows and zero flow events between the periods 1993-1995 and 1996-2011 were studied by analyzing hourly data from 8 regulated and 8 unregulated locations with four subdaily flow variation indices. No correlations between the market deregulation and the regulation intensity in the Ångerman River basin were detected. The number of days natural ranges of variability were exceeded and the magnitude of subdaily variation were significantly higher at regulated locations.
Långtidsfrisk eller arbetsglädje - vad speglar arbetsrelaterad hälsa?
The work related illness has increased and instead of focusing on what?s causing it more and more efforts are put on trying to find the health factors within and outside the work environment. During the past years the term ?long-term health? has arisen; instead of focusing on the number of employees on the sick-list, the focus should be put on the number of employees that has a record of long-term health within an organization, i.e. health-presence.
Makrostruktur och kohesion i berättande hos 6-åringar med och utan epilepsi
The purpose of this study was to examine the narrative skill of sixyear-olds in terms of macrostructure and cohesion, and its relation tonarrative content, auditory attention, auditory Short-term memory and threemeasures of word retrieval. A group comparison of macrostructure andcohesion was also performed between children with and without epilepsy.The material consisted of audio recordings of 44 children (18 with epilepsyand 26 from a reference group) retelling the story Nelli-sagan (Holmberg &Sahlén, 2000). No correlation was found between content and macrostructureor cohesion, but several between the latter two. Auditory Short-termmemory and word retrieval without pictures showed several correlationswith macrostructure as well as cohesion. No differences in macrostructure orcohesion were found between the children with epilepsy and the referencegroup.
Dinosaurien. En animerad kortfilm om mobbning
Although I myself haven?t been bullied per say during my school years. I?ve sure been teased and occasionally felt left out. On the other hand ? who hasn?t? And that as well is my point.
En novellsamling blir till
This essay discusses my proposed collection of short stories. The aim has been to examine the texts in terms of form and thematics, and position of the texts in a social context. First I present the collection, and then look at the texts from stylistic angle. I have chosen to use the concept of descriptive style. I have picked out certain parts of my texts in order to see which effect they have on the reader (in this case I).
Ett barn som alla andra? : En intervjustudie om familjehemsföräldrars uppfattningar om etnicitet
This study aims to examine how the interventions for homeless persons in the municipality of Kalmar are organized. The study is based on four half-structured qualitative interviews with both representatives from different instances and also from persons who have experience of being homeless.The theoretical bases we have used to analyze the material are organization theory, specifically the concept of bureaucracy. Our results show that homelessness is not seen as a problem in itself, since the general view is that homeless people often have a complex problem scenario where drug- and alcohol abuse and mental illness are common.It is often the latter that takes priority in the interventions and the housing question is therefore neglected. We also found that social services do not have a satisfactory structure around the organization of the work on homelessness. They do not have any specific device in Kalmar that focus on homelessness issues with the result that the existing units are forced to take care of the work of homelessness.
Den tunna röda linjen : identitet inom arkeologisk teori och metod
THE THIN RED LINE ? Identity in theory and method With this essay I want to explore some possibilities with the term identity within archaeology. Identity is a term best understood in the light of different scientific approaches. For instance the anthropological and historical angel combined with the quality of archaeology, as is the case in this essay. By combining these approaches, I create a (clarification) method of exploring traces of identity.By analysing two different graves from Scania, having a negligible number of artefacts from the Viking Age, and three graves from Bornholm, known for its large number of finds from this period, I test the ability of my method.

Impact of Eucalyptus plantations on pasture land on soil properties and carbon sequestration in Brazil
Soil organic carbon (SOC) stocks and fluxes in forest ecosystems are influenced by natural and human disturbances. In the tropical regions the highest impacts on disturbance in forest C cycles are related to human activities such as conversion of natural lands to cropland and pasture areas and to forest plantations. The disturbances in the forest C cycles will release CO2 emissions to the atmosphere triggering global warming. In this study the focus was set in subtropical soils in Brazil, south extreme region of Bahia. The aim of the study was to investigate whether reforestation of Eucalyptus plantations under former pasture areas will help mitigate climate change through carbon sequestration.
Är korta spenar ett problem i samband med mjölkning? :
In some herds it has been observed that extremely short teats have become a problem; with a negative influence on the milking performance. The aim of this study was therefore to investigate to what degree the quality of the teats and the milk in cows with short teats is affected as compared with cows with normal teat length and furthermore if the milking performance could be improved by using a liner adapted to short teats.
This study was divided in two parts. In the first part, it was examined if there were any differences between short teats and teats with normal length with reference to the milking performance, udder emptying, teat treatment, milk quality, and udder health. 11 pairs of cows were used and in each pair of cows one cow had teats shorter than 40 mm while the other cow had teats longer than 50 mm.
