Hur ser lavars fördelning ut runt stammen på ek, och påverkas den av trädets storlek och dess närmiljö?

The aim of this study was to describe preferences of geographic direction of ten, oak-living epiphytic lichen species and how they responded to sun exposure, nearby bushes and trees, bark fissure depth and circumference. The frequency of every species was recorded in arcs of ten degrees around the tree at a height of 130 to 180 cm above the ground. An estimation of the amount of every species in every arc was also recorded. To analyse how the distribution of the lichen species responded to the different factors their concentration for every tree was plotted against the four factors. The distribution of Cliostomum corrugatum had a positive response to high sun exposure and a negative response to a thick layer of bushes and trees.

Gilla, dela och kommentera ? Användarrespons på bibliotekets Facebookinlägg

The focus of this thesis is to examine posts on library?s Facebook pages and to investigate possible connections between posts and user response. The study examines posts published from thirty different libraries Facebook pages over a two week period to examine if any correlation between different subjects or types of posts affects the degree and type of response from the users.The findings show that photos stand for the majority of the published post concerning its type and that activities at the library was the most common subject of posts. After using eta as measure of association a tenuous connection between degree of response and the posts subject and between the degree of response and the type of post was found. The standard deviation, however, was high in the majority of the variables used.

I döda kungars sällskap : Historiebruk och historiemedvetande kopplat till Sverigedemokratisk ungdom på Facebook mellan 2010-2014

The investigation has taken place at an upper secondary school in the south-east of Sweden, involving 20 students in grade 2 and 3 in the course Swedish C. The investigation is based on the students? comments on their peers? speech drafts and six qualitative interviews.

Sjukdomsresistens eller sjukdomstolerans inom husdjursaveln - en jämförelse

Tolerance and resistance are two different defence mechanisms within the immune system that differ from each other in many ways: However it is not clear which of the two is the most advantageous in dairy production. Resistance is described as the ability to fight a pathogen in a host. Tolerance is, on the other hand, not aggressive to the pathogen per se, but rather protects the host and its tissues. Furthermore tolerance rather offsets the toxin from, for example, a parasite whilst resistance offsets the parasite itself. Resistance is however disease specific, which means breeding for a large number of diseases is needed in order to make resistance worth the cost for the host.

Globalt mode på en lokal marknad : - En case study av H&M och hur de väljer att profilera sig i deras globala kampanj, Conscious Collection

The aim of this research is to develop a better understanding of how preschool-teachers respond to children in preschool, when they show that they want to have some influence. I have concentrated this study on how the preschool-teachers respond to the children in the gatherings and when the children are playing freely indoors, where the questions at issue are:How do the preschool-teachers respond to the children?s initiative for participation in the gathering and while playing freely?There have been four preschool-teachers and 14 children who have taken part in this study. The children who took part are in the ages of three to five. The study was done at a section in a preschool in middle Sweden.The method used in this study is unstructured observations.

Immunisering för att minska ornelukt

Hundreds of thousands of piglets are castrated without anesthesia in Sweden every year so that we may be guaranteed meat without boar odor. The smell appears while cooking meat of boar and is described as urine- and sweat-like. High levels of androstenone and skatole are considered the main factors behind boar odor. Skatole is a metabolite of the amino acid tryptophan, which is formed in the colon of all pigs. Androstenone is a steroid hormone that is released from the Leydig cells in the testes of boars.

Värdet av demand response på den svenska elmarknaden

Intelligent IT-based solutions, often called Smart Grids, are considered to be the future balancers of renewable energy sources. One area within the Smart Grid concept is called demand response, which is focused on making customers more consumption flexible by making them more active in their consumption. In this thesis the aim is to analyze a business model by investigating the income potential for a demand response solution as well as its market potential. This has been done through literature studies, interviews and development of a computational model.The use of 5000 households with flexible consumption can provide a cost reduction of 17.2% or 2.4 million SEK for a balance responsible party during an average year. If the solution is used to make strategic bids on the regulation markets the study indicates that the largest potential for revenues lies within this strategy.

Insatsens akustik och dess påverkan på hörapparatens förstärkning

The earmould acoustics affect the amplification that the hearing aid is programmed to give to its user. It is therefore important that the choices made for the earmould are correctly done. One choice is regarding the shape of the soundbore that affects the frequency response of the hearing aid above a certain cut-off frequency. The purpose of this project was to measure the frequency response when altering the shape of the soundbore in the earmould. Additionally, the aim was to examine how the frequency response is affected when the shape of the soundbore is not set or is not possible to set in the software when programming the hearing aid.

Att genom design effektivisera räddningsinsatsen för motorcyklister i trafikolycka

What if the emergency response directly knew exactly where to go and what to do if a road accident occured? During the last ten years the number of motorcyclists in Sweden has doubled. Every year, more than 300 riders are seriously injured and over 40 die in road accidents. Being found in time is critical to increase the chance of survival. The goal of this project is to use design methods to find a solution that enables a fast and adequate emergency response for motorcyclists and other unprotected road users..

Uppfatta och reagera : En kvalitativ studie om IT-relaterade resursers roll i kundkännedomsprocesser och kundresponskapacitet

The structures of organizations have gone through a dramatic change over the last years; as a result customer service is no longer a small side activity but a critical part in customer relationship management. Development in information technology has created opportunities as well as challenges for organizations when it comes to providing a customer service with capacity of sensing and responding to customers' needs. Previous research shows a relationship between customer response capability and customer knowledge processeses, this study investigates and confirms this relationship. However, findings show that dedication and understanding for customers needs has a direct impact on both customer response capability and customer knowledge processeses, this result indicates that customer knowledge processes and customer relationship management are difficult to differentiate. Furthermore, this study explores IT-related resources impact on customer response capability and customer knowledge processes.

Jämförelse mellan ?Auditory Brainstem Response (ABR) och ?Auditory Steady State Response? (ASSR) för att uppskatta hörtrösklar på barn i narkos. Kan testtiden minska om 500 Hz utesluts vid ASSR-mätning?

ObjectiveThe objective of this study was to investigate the clinical application to use ASSR in anesthetized childrenDesignOne main ambition of the investigation was to compare hearing threshold using ABR with estimated hearing threshold using ASSR. Another aim was to examine if the duration of an ASSR measurement could be reduced by only using the frequencies 1, 2 and 4 kHz and exclude the frequency 0.5 kHz. This is a retrospective study using electrophysiological measurement from a database.ResultResults showed a high correlation between hearing threshold using ABR and estimated thresholds using ASSR, with the frequency 0.5 kHz showing a slightly lower correlation. Result also showed that the test duration was increased when using all test frequencies in ASSR-measurement compared to when 0.5kHz was excluded. ConclusionThe study showed a high correlation when comparing hearing threshold using ABR and ASSR.

Reader-response-kritiken och uppnåendet av estetisk känslighet - en uppsats om tolkning av skönlitteratur i 2000-talets gymnasieskola

Denna uppsats är en kvalitativ studie om svensklärares attityder och förhållningssätt till hur skönlitteratur används i undervisningen och om det görs några tolkningar av de lästa verken samt hur dessa tolkningar tar sig uttryck. Området som undersöks är i vilken utsträckning lärarna låter sina elever göra subjektiva tolkningar av de litterära texterna som de möter och om det är läsarens egen upplevelse och den estetiska känsligheten som eftersträvas i klassrummet eller om skönlitterära verk har andra värden som känns viktigare för yrkesverksamma lärare.Vad som också utreds är om lärarna på något sätt är influerade av reader-response-kritiken och om de anser att reader-response-kritiken har påverkat skolvärlden under 1900-talet.Undersökningen ger först och främst en bild av sex svensklärares inställningar och attityder gentemot användningen av skönlitteratur på gymnasiet. Dessutom redogör uppsatsen för olika teorier om reader-response-kritiken och estetisk känslighet vad det gäller tillägnandet av skönlitteratur och vilken bild kursplaner samt läromedel ger av hur läsning av skönlitteratur kan se ut i dagens gymnasieskola..

Evaluation of a new microarray method for genotyping of HLA-DQ2 and HLA-DQ8 for investigation of celiac disease

Celiac disease (CD) is an autoimmune disease, induced by an immune mediated reaction in the small intestine after ingestion of gluten and related prolamines. There is a strong genetic linkage and most important are the genes that encodes for HLA-DQ2 and HLA-DQ8. The European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) has developed new guidelines for investigation of CD in children and adolescents, which include genotyping for HLA-DQ2 and HLA-DQ8. Therefore, the clinical microbiological laboratory in Västmanland wants to introduce a method for analysis of these genes. Microarray is a newly developed method for determination of the alleles HLA-DQA1 and HLA-DQB1 that encodes for the ?- and ?-subunits of the HLA-molecules.

Micro plastics in the oceans and their effect on the marine fauna

Small pieces of plastic, termed ?micro plastic? in the oceans derive mainly from degradation of big plastics such as beach littering, but also from sources of direct emission from e.g. beauty scrubbers and synthetic sand-blasting. These micro plastics are ingested by marine animals ? mistaking them for plankton ? or via prey.
