Obalans mellan rot och krona skapar omplanteringschock i Prunus avium :
In this investigation has an attempt to find out whether so called transplanting shock depends on the moving and transplanting of trees, to other conditions, or if it is due to the imbalance between the root to shoot ratio. Seventy trees of Prunus avium have been part of the investigation and these trees have been divided into four different groups depending on methods of production, untouched on the field, trees still on the field but with root pruning, trees moved and planted into Root-Control-Bag, trees moved and planted into Spring-rings. To be able to answer the question, measurements of the length of the terminal shoots and the lateral shoots and the dimension of the stem growth have been done and also has a visual judgment of the trees vitality been performed. The result shows that it is not only the move of the trees that gives them transplanting shock, but rather the loss of roots which gives an imbalance between the root and crown..
Det första könet, dess ?Andra? och den tredje världen : västerländsk manlighet i reseskildringar
Travel literature and especially the ?adventure story? has excited young British boys for over two centuries. However, it has also been a vehicle for the assertion of male dominance and European supremacy. The story of a British man who goes to the colonies, performs some test which is essentially a test of his manliness, and whose compulsory victory marks the end of the book, has been a central myth in colonial masculinity.Through looking at three Anglo-Saxon male travel writers from the 20th century, this essay aims to study the different ways in which Western male identity is shaped against an Indian background. The novels analysed are Topee and Turban or Here and There in India by H.A.
Mätmetoder för eldrivna rullstolar
Detta examensarbete har utförts i samarbete med Permobil AB. Det ursprungliga målet med arbetet var att göra ett antal mätningar på elektriska rullstolar, för att om möjligt kunna komma fram till en repeterbar metod för att exempelvis kunna jämföra olika motoralternativ på en rullstol eller jämföra dom egna rullstolarna mot konkurrenternas på ett rättvist sätt. Efter att ha granskat och testat den utrustning som fanns tillgänglig på Permobils designavdelning så kom vi fram till att vi var tvungna att utöka målet med arbetet till att även omfatta konstruktion av ett mer avancerat mätsystem än det befintliga. Det som arbetet till slut kom att omfatta och som även denna rapport behandlar, är alltså test och utvärdering av befintlig utrustning, konstruktion och test av ny utrustning samt en serie mätningar som gjorts på olika rullstolar för att ta fram en repeterbar mätmetod. Denna rapport riktar sig främst till personer med åtminstone grundläggande kunskaper i elektronik och mätteknik..
Utprövning av ett situationstest för chefer
Studiens syfte är att validera ett ledarskapstest (TKB) som för närvarande är under utveckling. Testet mäter ledares kognitioner, emotioner och beteenden i mötessituationer. De 65 respondenterna var alla verksamma som arbetsledare, mellanchef eller chef på högre nivå och bestod av 33 män och 32 kvinnor i olika åldersgrupper och branscher. En jämförelse gjordes mellan TKB-testet och Gordons test samt med skattningar utifrån utförda intervjuer. TKB-testets variabler jämfördes även med olika bakgrundsfaktorer.
Vid vilken glukosnivå frisätter kor insulin? :
Six cows were subjected to an intravenous glucose tolerance test (GTT) to evaluate the amount of glucose that is needed to stimulate the release of insulin from pancreas. Four of the cows were in early lactation and two were non-lactating and not pregnant. Series of blood-samples were collected to analyze the concentration of insulin and glucose in the blood. The cows were given lower levels of glucose than have been used in earlier glucose tolerance tests. The levels of glucose given were 7,5 mg/kg BW, 15 mg/kg BW, 30 mg/kg BW and 50 mg/kg BW.
Testmetodik för vintertestning av el- och hybridfordon
With gas prices persistently rising, electric and hybrid vehicles are getting more and more common and in recent years several new electric cars have evolved on the market. Although the energy consumption and low emissions are a huge benefit of the electric cars, they inevitably suffer from high prices, short range and time consuming recharging periods. To be able to withstand the competition it is important that electric vehicles not only can withstand general were and tare, but also the harsh conditions that ordinary cars is exposed to in daily usage. The purpose of this project is to develop a test methodology which replicate situations that could appear in daily usage of electric or hybrid cars and to understand the problems related to usage of electric cars in winter conditions. This paper also discusses the major differences between hybrid cars and electric cars.
Evaluating six crop mixes used for game fields in southwest Sweden : biomass production, fallow deer preference and species diversity
Game fields are one way to divert animals away from sensitive areas, create shelter and forage, and also to increase the biological diversity. In this study I investigated how the plant composition in six different crop mixes used for game fields affected the biomass production, biomass consumption and biological diversity at the Koberg estate in southwestern Sweden. Six experimental fields were used and each field contained six plots, approximately 1500 m2 each, that was sown with a different crop mix. The crop mixes ranged from a pure grass mix (A), 70 % grass and 30 % leguminous plants (B), 53 % grass, 21 % leguminous plants and 26 % other herbs (C), 100 % leguminous plants (D) to the most complex mixes constituting of 91 % leguminous plants and 9 % other herbs (E) and 87 % leguminous plants and 13 % other herbs (F). The fields were cut weekly during the summer in 2010, to estimate weekly biomass production.
Metodik för resistenstest i renkavle : en studie om herbicidresistens; mekanismer, detektion och åtgärder
Herbicide resistance is the result of an evolutionary process where a population gradually changes from being susceptible to being resistant to an herbicide. The resistance mechanism is usually a change in the biochemistry of the weed, but in some cases changes in morphology or growth rhythm. The change is caused by random mutations. Two resistance mechanisms are found in black-grass; target site resistance and metabolic resistance.Black-grass is a tufty, winter annual grass weed, which is mainly found in milder climates. Black-grass is a big problem in Southern Europe.
Självskattad hälsorelaterad livskvalitet hos kvinnor och män med fetma
Fetma utgör ett folkhälsoproblem. Fokusering på vikt och olika risker med fetma är otillräckligt för att förstå hur personers hälsorelaterade livskvalitet påverkas. Studiens syfte var att beskriva självskattad hälsorelaterad livskvalitet hos personer med fetma. Kvantitativ ansats valdes och 100 personer med ett BMI mer än 30 besvarade ett självskattande instrument, SF-36. Dataanalys genomfördes med korrelations test för att få styrkan i samband mellan variabler.
Livskvalitet efter en hjärtinfarkt. Sjuksköterskans stödjande åtgärder.
As a public nurse there is a great probability that you will meet patients that have had a myocardial infarction. We want to contribute to create a greater understanding of how a nurse can support and understand these people. The last 30 years the infarction care has made a big progress. Still many conceptions remain which means that for many people a myocardial infarction leads to a belief that this is the end of the working life, social life, sparetime activities and travelling. Due to this misbelief it is important that the nurse creates good conditions for the patient right from the start.
Löslighet och metylering av kvicksilver i en förorenad sjö (Ala-Lombolo) i Kiruna kommun :
Transformation of inorganic mercury (Hg) to methyl mercury (MeHg) is a biotic process that is proposed to be conducted primarily by sulphate reducing bacteria (SRB). The formation of MeHg is of great interest because it is the mercury species that biomagnifies to the greatest extent in the aquatic food webs; about 90 % of all Hg in fish is MeHg. Our understanding of factors involved in the production of MeHg is very important for making a reliable risk assessment. The purposes of this study were to investigate the different factors that control the solubility of Hg and the production of MeHg in a contaminated lake sediment.
The lake Ala-Lombolo, Kiruna municipality, is well-known to be contaminated by mercury from different sources. Sediment cores were sampled at three different locations (N, SW and SE) in the lake and divided in three different layers; 0-5, 5-10 and 10-15 cm.

Simulatorträning som ett redskap för att förbättra procedurell kunskap
Anestesören arbetar i en miljö som är dynamisk och komplex vilket gör att det krävs att de kan utföra sekvenser av moment på automatik eftersom det oftast inte finns tid till djupare beslutsöverläggningar. Vid Huddinge Unviersitetssjukhus finns METI som är en patientsimulator. Denna simulator används idag för att öva medicine kandidater i att ge anestesi. Detta arbete undersöker om simulatorträning kan förbättra medicine kandidaters procedurella färdigheter. Undersökningen är en enkätundersökning där frågor som sökte ta reda på deltagarnas procedurella ställdes.
Äldre dövas arbetsminne
Denna studies syfte var att undersöka om dövas åldersförändringar i arbetsminnesbearbetning skiljer sig från hörandes. Fyra grupper deltog, döva (teckenspråkiga) och hörande (icke teckenspråkiga), indelade i grupper om yngre och äldre (> 65 år). Femtiosex personer deltog, jämnt fördelade över de fyra grupperna. Samtliga fick genomgå ett arbetsminnestest indelat i tre delar, ett spatialt, ett temporalt och ett spatialt - temporalt test. Den spatiala naturen hos teckenspråket förväntades leda till en relativt sett förstärkt funktion i detta test hos de teckenspråkiga.
Aquaculture : animal welfare, the environment, and ethical implications
The aim of this review is to assess the ethical implications of aquaculture, regarding fish welfare and environmental aspects. The aquaculture industry has grown substantially the last decades, both as a result of the over-fishing of wild fish populations, and because of the increasing consumer demand for fish meat. As the industry is growing, a significant amount of research on the subject is being conducted, monitoring the effects of aquaculture on the environment and on animal welfare. The areas of concern when it comes to animal welfare have here been divided into four different stages: breeding period; growth period; capturing and handling; and slaughter. Besides these stages, this report includes a chapter on the current evidence of fish sentience, since this issue is still being debated among biologists.
