Effekter av gödsling i äldre tallbestånd på renbetesväxter i fält- och bottenskikt :
Reindeer husbandry and Forestry are both area related industries and will in big extent use the same lands. Conflicts often arise because of that the industries have different interests. Many of the activities done by the forestry influences the reindeer husbandry in an undesirable way, simultaneously as the reindeer husbandry activities can have negative consequences for the forestry. One such forestry activity is fertilization.
It was during the 1960´s forest fertilization began to be practiced and the reason was that the increase in growth that the fertilization gave could be able to cover for the future shortage in wood many feared.
During the 1970´s when the fertilizing activities were most intensive about 200 000 ha was fertilized annually.
En jämförande undersökning om förloppet vid terapeutiskt utförd KAT-töjning och statisk egentöjning: Single Subject Experimental Design
Bakgrund: En stram muskel kan orsaka ett försämrat rörelsemönster som i sin tur kan vara orsaken till skada, detta kan dock motverkas genom stretching (töjning). Syfte: Syftet med studien var att undersöka hur och om rörelseökning i hamstringsmuskulaturen skedde genom töjning med KAT-metoden respektive statisk töjning under en töjningsperiod på tre veckor. Metod: Förloppet kring stretching av hamstringsmuskulaturen undersöktes genom töjning varannan dag under 10 interventionstillfällen. Studien genomfördes som en Single-Subject Experimental Design (SSED). Baseline och withdrawalmätningar grundlades där inga töjningar utfördes.
Smärtskattning med validerade smärtskattningsinstrument - en interventionsstudie
AbstractPain among patients in their final stage of life is a commonly occurring problem. Results fromthe Swedish Register of Palliative Care (SRPC) indicate that validated instruments forassessing pain are rarely used. Nurses' insufficient knowledge of pain and pain treatmentmethods may be a cause of maltreatment of patients who suffer from pain.The goal of this study was to determine whether training within the area of pain, painassessment and pain assessment instruments increases the use of validated pain assessmentinstruments utilized by nurses working in care homes for patients in the final stage of life inthe city of Uppsala.Method: A quantitative and quasi-experimental design was selected to perform the study.The intervention study that was used consisted of one training session where onequestionnaire was given before and one after the time of training. Register data were collectedfrom the SRPC given the question of pain assessment before and after the intervention.Results: The study showed that nurses more often used pain assessment instruments after thetraining session. The results also showed that nurses to a greater extent than before alternatedbetween the two validated pain assessment instruments that were introduced at the trainingsession.Conclusion: The results showed that when nurses at care homes are given training in the areaof pain and pain assessment they absorb and use the newly acquired knowledge in theirclinical work..
Amning av prematurfödda barn : En interventionsstudie om mammors tillit och vårdpersonals attityder
Background: Breastfeeding frequency decrease in Sweden and infants born preterm is a particularly vulnerable group to not be breastfed according to current recommendations. Mothers of preterm infants have an extra need of support from the health care system. Mothers' self-efficacy in breastfeeding affects the outcome of breastfeeding. Health professionals' attitudes to breastfeeding have an impact on the breast feeding support they provide to the mothers.Aim: To investigate whether an intervention could strengthen self-efficacy in breastfeeding among mothers of premature babies. A further aim was to investigate whether the intervention influenced health professionals' attitudes to breastfeeding.Method/Design: An experimental study with quantitative approach in the form of questionnaire survey was conducted.
Va?rdering av varuma?rken : - En kvalitativ studie om problematiken kring vilken metod som anva?nds vid fo?rva?rv
Background: Associated with the change in the regulations in 2009 concerning how goodwill should be handled in the acquisitions, brand valuation is increasingly recognized. Goodwill will now be identified and the brand will therefore be separated to be individually evaluated. The valuation has a problem with a number of factors that will influence the choice of method, to obtain a reliable value Aim: The purpose of this study is to examine the method used for brand valuation associated with the acquisition situations. In addition, it aims to gain a better understanding of brand valuation and its problems.Method: The study has a qualitative basis, where three key people of brand valuation have been interviewed. These work as valuation specialists at various accounting firms, this to get answers that could be compared.
Under parasollen : En komparativ studie utifrån whole language-teorin och LTG-metoden
AbstractThe purpose of this study is to analyse the reading- and writing-approaches: the LTG-method and the whole language-theory. The attention is to perform a comparative literate-study to distinguish their similarities and differences, and examine which one of the approaches that is most clearly anchored in the syllabus of the subject Swedish. The starting-point of the study is the questions: Which similarities respectively differences have the LTG-method and the whole language-theory? Which one of these theories is most clearly anchored in the syllabus of the subject Swedish? The study has shown that both the whole language-theory and the LTG-method can anchor in the syllabus for Swedish. However the whole language-theory has stronger hold in the syllabus, as the whole language emphasises the meaning of literature for reading- and writing-learning, and considers the pupils reflection during their learning-process and conquered knowledge-goal.
Ventral Töjning Pectoralt (VTP) som behandlingsmetod vid ett avvikande hållningsmönster i nacke och axlar : Single Subject Experimental Design
De senaste årtiondenas explosionsartade teknologiska utveckling har gett oss möjlighet till en mer stillasittande och inaktiv livsstil framför skärmbundna aktiviteter som datorer, surfplattor och smartphones. Det leder till en avvikande hållning. En avvikande hållning i nacke och axlar definieras som ökat framskjutet huvud, ökad thorakal kyfos samt protraherade (framskjutna) axlar. Genom ökad aktiv eller passiv tension av pectoralis minor har forskare antytt att det kan påverka skuldrans kinematik för individer med nack- och skuldersmärta. Syftet med studien var att utvärdera om töjning av pectoralis minor med behandlingsmetoden Ventral Töjning Pectoralt (VTP) har någon inverkan på individens avvikande hållning genom korrigering av axlarnas och nackens position.
Tvådimensionella rum
We are always surrounded by space, not just only in a room with four walls, but also when we are outdoors.Constantly we move in a flow of space that changes whenever we move. Unaware we are affectedby this threedimensional surrounding of ours, and it reacts with our perception. Many times, we chooseto translate it into something two-dimensional, for example when we take a photo, recording a movie orframing a view with a window. It helps us to catch a moment, a piece of reality and restore it in our ownway. In this project I?ve chosen to explore this process, to interpret and create my own theories about thistranslation from space to a two-dimensional surface.
Utveckling av HPLC-metoder för kvantifiering av nyckelkomponenter i en villkorad emulsion
Traditionally, rolling mills use emulsions based on a mixture of oil and water for lubrication. Since two years ago SAPA has been using (instead of oil) a synthetic lubricant so called conditional emulsion for hot-rolling of aluminum. This lubricant is water based and homogenous at ambient temperature, but switches to a two-phase system at heating above the cloud point.This project aims to validate and if necessary modify an existing HPLC method for quantifying two out of three key components (A, B and C) in the conditional emulsion. Attempts to develop a method to quantify the pH adjusting components, X and Y were also made. These two methods are required to optimize the lubricant.Due to the complexity of the components, it has been difficult to present a method for quantification, and HPLC with ELS detection was chosen after a long series of trials.
Finns det någon cross-overeffekt mellan statisk och dynamisk uthållighetsträning av bålmuskulaturen, och hur påverkar de olika träningsformerna resultatet på ett bålstabilitetstest?: En studie med single subject experimental design
Bakgrund: Bålträning kan användas vid prevention, behandling samt för att öka prestationsförmåga. Vilken typ av bålträning som är lämpligast för de olika ändamålen är dock fortfarande oklart, vilket till viss del beror på brist på tydliga definitioner inom området. Mot bakgrund av specificitetsprincipen inom träningslära och bålmuskulaturens olika indelningar och dess muskelfysiologi, vill författarna undersöka om en cross-overeffekt kan uppnås mellan två olika typer av uthållighetsträning, liksom träningens effekter på bålstabilitet. Syfte: Syftet var att beskriva observerade och mätbara effekter av dynamisk bålträning på statisk uthållighet i bålmuskulaturen, och omvänt, samt de observerade och mätbara effekterna av de respektive träningsformerna på resultatet av ett bålstabilitetstest. Metod: Studiedesignen var single subject experimental design (SSED).

P?m?rkning vid virkesberedning - Bastning. Ett hantverksf?rs?k
This essay aims to investigate a rare method of marking up timber before hewing it. The
method for marking up timber is by eyesight, where visual judgment and the use of a broad
axe are the tools employed. The broad axe is driven through the bark and exposes the inner
bark in a straight line. The method is described by a craftsperson dating back to the 1930s.
There is a lack of information regarding the method.
Växtinventering och skötselåtgärder : en studie av Rektorsgårdens trädgård i Uppsala
The Bovine respiratory syncytial virus (BRSV) causes bronchiolitis and interstitial pneumonia, predominantly in calves, and is a major cause of bovine respiratory disease worldwide. In humans, BRSV is paralleled by the closely related Human respiratory syncytial virus (HRSV), an important cause of respiratory disease, most severe in infants.The clinical signs and pathology during RSV infection is caused, not only by the direct effects of viral replication, but also by the response of the host immune system. The immunopathology of RSV has long obfuscated our understanding of the disease, and development of effective treatment and vaccines will be very difficult until greater knowledge is gained.One of the components of the immune system that has come into focus in RSV research the last few years, is the Toll-like receptor 4 (TLR4). The TLR4 receptor is well known as the receptor that binds lipopolysaccaride (LPS), and initiates the host response to bacterial infection. Recently, it has been shown that the fusion protein of RSV also interacts with, and up-regulates the expression of, the TLR4 receptor.
Frilekens betydelse för barn i förskolan : En kvalitativ studie av några pedagogers syn på den fria lekens betydelse för barns lärande
The aim of this study is to increase knowledge and understanding of free play or free fun time importance for children of age around five years in preschool, in order to promote children?s development and learning. The focus was on exploring and better understanding of teacher?s and educators? approach to the free fun play time as a tool in their educational work, and also about their own role in this context as well as analyzing of forms, rules and structures spontaneously created by groups of children having free play fun time. Another important moment of this study was to give more light on approaches to this issue in education theories by Piaget, Vygotsky and Freud among others.As to the practical experimental part of the study it has been performed at a preschool and kindergarten in a suburb at the outskirts of Stockholm, with four employed educators there and with groups of children of age around five.
Enumerating Atlantic salmon smolt production in River Vindelälven based on habitat availability and parr densities : consequences of using different density estimation methods
Habitat mapping was conducted in the main stem of River Vindelälven in the autumn of 2009 along the salmon distribution area. The aim was to estimate the quantity of potential reproduction areas, including spawning and juvenile rearing habitats. The mapping included 61 km of various stream sections along the river length of 269 km. The total area of stream habitats was estimated to 647 ha of which 396 ha (61%) were considered as either potential or optimal juvenile nursery habitats. The area of these two habitat classes were used to estimate the smolt production in the river by using electro fishing densities of juveniles (0+ per 100 m2).
