Energi och klimatanalys O-huset på Campus i Halmstad

AbstractThe indoor environment affects the human performance. Noise pollution, poor lightning and coloring are some of the factors that affect our work performance. The human is also affected by the air change and temperature, these factors are in most buildings possible to adjust and through this make economic savings. To find out about the indoor environment in the O-building a questionnaire was handed out, measurements/surveys and an interview was also made. 108 questionnaires where handed out to employees and students.

Trä och fukt ? Mätmetoder för fuktrelaterade dimensionsförändringar hos trä och deras användbarhet, med två fallstudier inom konservering

This thesis deals with different methods for measuring moisture-related dimensional changes ofwood. Typically relative humidity is measured to determine if the ambient climate around anobject is harmful to it or not. Values between 40 to 65% RH are recommended for hygroscopicmaterials. To know how a wooden object actually reacts to changes in the surroundingenvironment requires methods that involve the object itself. Because of the wood anisotropy,differences in wood structure, finishes and other restraints, it is not always possible to predict themovements.This paper addresses various measurement methods, primarily methods that have been testedin the field of conservation, with examples of their use.

?Ett spöke går runt Europa- kommunismens spöke? : En studie av religionsläromedel med fokus på den marxistiska livsåskådningen mellan åren 1970 och 1991

In the late 20th century the Soviet Union collapsed and the eastern European countries were freed from the communist Russian oppression. However, during the Soviet period Marxism was a recurring life stance in the Swedish textbooks for religious education in the gymnasieskola. Today the Soviet Union has collapsed, but the Marxist philosophy has had a huge effect on both single individuals and the modern society as a whole. Nonetheless, the Marxist life stance is nowadays often being replaced by other non- religious life stances in the textbooks of religious education.Therefore, this analysis is a hermeneutic study of the presentation of the Marxist life stance in textbooks for Swedish religious education. The purpose of the paper is to investigate how these textbooks portray the Marxist life stance, and to prove that the societal context and the individual author have an immense effect in the portrayal of both religions and life stances in religious education.

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.

What influence does Tai Chi have on the risk for falling among elder?

Background: 2007 there was 42 000 fall related accidents in Sweden and they are expected to increase the next few years. Fall among elders results in both increasing economically costs and suffering, but they can be prevented. For example has physical exercise shown an increasing effect on the risk for falls. Aim: The aim of this literature review was to investigate what influence Tai Chi has on the risk for falling among elder. Method: A literature review was conducted where eleven scientific articles were analysed with inspiration of the content analysis.

Effekten av traktkil på det distala benets rörelsemönster hos travhäst :

Changing of the hoof angle is a common method for the treatment of many lameness-related conditions (Moyer 1980; Stashak 2002). Various studies in the literature have indicated different results of the effect of changing the hoof angle on the movement of the distal limb. Our study investigated the effect of raising the heel of the forelimbs by 10,7 mm on the movement of the distal limb. Horses trotted on a treadmill at several predetermined speeds. The kinematics of the distal limb was determined and variables including the extension of the fetlock joint were determined.

Lönsamheten av analytikers riktpris - En studie av svenska bolag handlade på Stockholmsbörsen

We acknowledge the lack of empirical studies of the performance of analyst target prices in the Swedish stock market by examining the profitability of target prices for stocks publicly traded on the Stockholm Stock Exchange. We use consensus target prices issued between 2006-2010 and create two different strategies to observe the abnormal returns generated during this period. Going long in the top decile stocks with the best target prices and going short in the bottom decile stocks with the worst target prices generates a statistically significant abnormal buy-and-hold return of 8.9%. An active strategy with daily portfolio rebalancing and a timely response to target price changes generates a less significant monthly alpha of 1.4% against CAPM. The results show to be robust against the size effect discovered by Fama and French.

Flödesmätning i vattenkraftverk : Studie av alternativa mätmetoder

Flow measurement is one of the greatest challenges in order to calculate efficiency in hydropower. Most hydropower plants in Sweden use differential pressure methods for flow measurement. These methods are dependent on constant conditions in the waterways. A change in these conditions, like turbine improvements, prevents differential pressure methods to verify efficiency improvements. Since efficiency improvements can?t be verified by one measurement system, another method, which isn?t affected by changing conditions, can be used.

Rökgaskondensering och skrubber till vedeldade villapannor :

This paper deals with the opportunities for the technique of condensation, for wood fired household heaters, on the Swedish market. In this project the condenser is preceded by a scrubber and both energy exchange and separation of unburnt particles have been studied. The facility studied is connected to a wood stove at 30 kW. The tests would show that the effect from the stove never reached above 16 kW. This might be a result of the low temperature of the water going into the stove, from the condenser. In addition to this the wood was not of highest quality and the stove could have needed some maintenance before the tests.

Humankapitalets roll vid företagsvärdering

This study investigates a method for identifying human capital and its effect on company valuation. We devise a measure for the efficiency of human capital based on the personnel cost. We include all companies listed in the financial and industry sector on Nasdaq OMX Stockholm in an attempt to examine human capital and its effect on firm valuation. Our results indicate that a higher efficiency of human capital has a positive effect on return on assets. However, we find that our measure can be interpreted in two ways; either as a firm?s level of human capital efficiency or its dependency on human capital, to achieve its net sales and revenue.

Närståendes uppfattning av den äldres vårdbehov i samband med samordnad vårdplanering

Introduction: The population of Sweden has during the last century doubled. An increased live expectancy results in an older population and the share needing medical care increases. Demographic and political changes in developed counties have resulted in changed demands on the care of the elderly. The elderly are discharged from hospital earlier and this results a significant responsibility on the elderly themselves and their relatives. Often the relatives are engaged in the elderly?s health problems, care needs and the future consequences the current situation results in for the elderly and the domestic life.

Närståendes delaktighet vid vård av äldre : -bemötande, tillgänglighet och information

Studies show that older is an increased proportion patients in hospital and that it is a patient group that can be difficult to communicate with because of older patients' often multiple disease picture. Relatives to the patient can be help for caregivers in the communication and the care of the patient. The aim with the study was to examine relative's experience of participation, meeting/support, accessibility and information on a geriatrics rehabilitation care unit. The study had a descriptive design and was designed as a questionnaire study. It was implemented on one geriatrics rehabilitation care unit on the countryside in central Sweden, belong to Uppsala University hospital.

Ämnessökningar med kontrollerad vokabulär och naturligt språk: en jämförande studie med felanalys.

The aim of this thesis is to compare the effectivity of using a natural language and a controlled vocabulary when performing subject searches in the bibliographic database LISA Library and Information Science Abstracts. 20 topics were created and for each topic two searches were made, one by using a query formulated with natural language directed to the abstract field and the other one by using a query formulated with descriptors from the thesaurus in LISA directed to the descriptor field. The average relative recall amounted to 64,8% for the AB-queries and 54% for the DE-queries. Failure analysis showed that the majority of the relevant documents not retrieved by AB-queries could have been retrieved with other query terms, such as synonyms. In a natural language there are many different ways of expressing a topic, and this tends to have a negative effect on retrieval effectivity.

Biologisk bekämpning av Fusarium graminearum

Fusarium graminearum causes reduction in both yield and quality in cereal grain worldwide. One of the diseases it can cause is Fusarium Head Blight (FHB). Both sexually and asexually produced spores can infect living plants. Asexual conidia are produced in the mycelium while sexual ascospores form in asci in perithecia on debris. In biological control, living organsims are used to control pests and diseases.

Kontrollerad vokabulär eller naturligt språk? En empirisk studie.

The question whether controlled vocabulary or natural language free-text terms is the most effective search strategy has occupied researchers in LIS for many decades. This Masters thesis is an empirical study which aims to compare these two search strategies in LISA Library and Information Science Abstracts, an online bibliographic database. 22 topics from the discipline of Library and Information Science were constructed and out of each topic one query for each search strategy was formed. Queries in natural language were formed with terms from different sources, for example dictionaries, while queries in controlled vocabulary were built with terms from LISAs electronic thesaurus. The measures used in this study were precision, relative recall pooling method and overlap.
