The purpose of this study is to analyze the economic effects of different fertilization programs both on stand- and forest-level. The study is applied on an objective sample of inventory data for a forest area in Kalix in northern Sweden. The forest area belongs to the forest company Sveaskog. The study includes different economic models and will be used as a support when the company decides how to invest and how much to invest in fertilization. The study investigates the economy of five different fertilization policies. For each program the rate of interest invested in fertilization and the cost for the extra produced volume has been calculated.

Det perfekta kroppsidealet gör sig ofta påmind i samhälls- och mediadebatten. Dagens västerländska kroppsideal domineras av en smal och fettfri kvinnokropp. Under tonåren är fokuseringen på kroppen mer påtaglig än under någon annan del i livet. Strävan efter det slanka idealet är svårt att uppnå och kan medföra att individen inte förmår att acceptera sin kropp. Syftet med denna studie var att få en bild av och jämföra kroppsuppfattningen hos unga kvinnor som går på gymnasiet i Luleå respektive Jokkmokk.

The aim of this study was to examine bilingual childrenslexical organization and to investigate weather bilingual children hadundergone the syntagmatic-paradigmatic shift in grade four. Thirtychildren from multi-ethnic areas were tested with Kent-Rosanoff wordassociation test in both Swedish and Arabic. The results showed thatmore than 40% of the children had undergone the shift in bothlanguages, 20 % had undergone the shift in only one of theirlanguages and almost 40% had not made the shift in any language. Acomparison with results from monolingual Swedish children in gradethree in a previous thesis, showed that the bilingual children in thisstudy did not reach the corresponding level of lexical organization.The study points to the necessity of including tests regarding lexicalorganization when assessing both mono- and bilingual children withsuspected language impairment. The study also underscores theimportance of supporting mother tongue development in bilingualchildren by for instance adequate mother tongue education.

The flagellate Giardia intestinalis has been known to cause diarrhea in both man and dog. Results from epidemiological studies have indicated that transmission of the parasite from dog to man is plausible even though that route of infection has yet to be shown. Several international studies have shown that the parasite frequently occurs in asymptomatic dogs. In Sweden the prevalence of Giardia in healthy dogs is not known though. In this study, faecal samples were collected at two separate occasions from 21 litters and 21 bitches showing no symptoms from the gastrointestinal tract. The samples from each litter were pooled but the samples from the bitches were analyzed individually.

Every spring you can see newborn foals running on fields among the mare. But some unfortunate end up visiting the equine hospital requiring surgery. This is a challenge for the anesthetist because of the neonatal foal?s unique physiology. Therefore you need to take these differences under consideration when you anesthetize foals.

Denna studie avser att ta reda på om någon förändrad effekt kan fås gällande bränsleförbrukning och emissioner då dieselolja strömmar igenom ett magnetiskt fält innan det förbränns i en dieselmotor som driver en generator. Utrustningen som ger upphov till magnetfältet har tillhandahållits av ett kommersiellt företag. Studien består av två delar, en teoretisk del och en praktisk del. I den teoretiska delen presenteras tidigare vetenskapliga studier inom ämnet samt hur tillverkaren av utrustningen menar att tekniken fungerar. I den praktiska delen har tester gällande rökgasemissioner och bränsleförbrukning gjorts.

This report contains a degree project made by the mechanical engineering students Lennart Andersson and Daniel Jansson. The project has performed in assignment by SOMAS Valves AB in Säffle. SOMAS are leading in development on control and on/off valves. To maintain this position they always want to improve their products. One way in this development is valves that are more tightened.The purpose with our project was to investigate another seat design on a HiCo (High Cobalt Alloy) seat to a SKV 150 PN 25 valve and compare this to an original HiCo seat.By modifying the seat on a ball valve we want to achieve a valve that leaks lesser then a valve whit original seat.

The main purpose of this Master´s thesis is to examine how Swedish librari-ans manage and relate to social problems within the service to young visitors. To reach understanding in this subject, qualitative interviews with six Swedish public librarians have been conducted. As a theoretical framework the ideas of interactions and identity have been used. These concepts together with attitude and behavior, form the theoreti-cal model upon which the analysis of the material is based. The outcome of the study shows that social problems exists and affect the library staff?s daily work.

The purpose of this thesis is to show how to use vulnerability testing to identify and search for security flaws in networks of computers. The goal is partly to give a casual description of different types of methods of vulnerability testing and partly to present the method and results from a vulnerability test. A document containing the results of the vulnerability test will be handed over and a solution to the found high risk vulnerabilities. The goal is also to carry out and present this work as a form of a scholarly work.The problem was to show how to perform vulnerability tests and identify vulnerabilities in the organization's network and systems. Programs would be run under controlled circumstances in a way that they did not burden the network.

Coreträning består av statiska och dynamiska övningar för bålmuskulaturen. Syftet med studien var att ta reda på om det fanns ett samband mellan bålmuskulatur och balans samt om en träningsperiod med Coreträning kunde påverka balansen. En litteraturstudie har gjorts där åtta artiklar granskades. Dessutom bestod studien av en empirisk del där nio försökspersoner fick sin statiska och dynamiska balans testad före och efter en 4-veckors period med Coreträning. Som mätmetod användes unilateral stance test med NeuroCom® Balance Master® 8.03 och dynamic balance test med Biodex® Balance System.

The objective of this study was to get a better understanding of how the cultivation methods influence the vitality in Prunus avium. The purpose was also to examine if there was any differences in shoot growth and trunk expansion depending on the method of cultivation. To find the answer to this question a literature study and a case study has been done. The literature study concerns the concepts vitality and stress. Different definitions of these concepts are shown and their connection whit establishment is explained. In the background the species Prunus avium, and the four method of cultivation that are included in this case study are described. Measurements of the shoot growth and trunk expansion were made in this study, and as a complement to these methods, a visual estimate of the vitality was made.

Background: The Swedish population is aging [1] and malnutrition is a common problem among elderly people [2]. A method called food registration is used to monitor the patients? nutritional intake, with the purpose of reducing the risk of patients deteriorating in nutritional status during hospitalisation. However, the current method is not satisfactory and many food registration lists are incomplete. [3-6] Thus, patients do not receive a qualitative nutritional care since the assessment of the patients? nutritional status is based on incomplete documentation.Purpose: The purpose of this master thesis is to increase the quality in the nutrition monitoring process in the geriatric units B72 and B74 at Karolinska University Hospital in Huddinge, Sweden.

Syftet med uppsatsen är att besvara frågan om andraspråkselevernas ordförråd påverkar deras resultat i skolans matematikundervisning. Materialet i studien utgörs av tolv andraspråks­elever och tolv svenskfödda elever i årskurs 8. Jag har låtit eleverna genomföra ett test i tre delar; det första testet består av lästal, det andra av ordförståelse och slutligen det tredje av numeriska tal. Samtliga test hör ihop och testar på detta sätt elevernas förmågor på tre olika sätt. I studien ingår även en räknesaga, där eleverna själva får skriva ett benämnt tal.

Bakgrund: Test av syreupptag (VO2) kan fungera som en utvärdering av träningen för idrottare. VO2-test kan även nyttjas för att synliggöra anställdas eventuella hälsoproblem inom ett företag. Det finns idag en rad olika stationära och mobila utrustningar som mäter syreupptag (VO2), koldioxidproduktion (VCO2) och minutventilation (VÉ). Ett exempel är Jaeger Oxycon Mobile, bärbar VO2-utrustning, som kan användas i idrottarens eller arbetarens normala arbetsmiljö. Det finns idag inga publicerade studier där validiteten hos Jaeger Oxycon Mobile har testats.

De genusrelaterade skillnaderna inom fenomenet smärta är en aspekt som måste betraktas i omvårdnadsarbetet. Många faktorer påverkar smärtupplevelsen och sjuksköterskan måste ta hänsyn till dessa för att kunna göra en korrekt bedömning. Syftet med denna studie var att undersöka om det fanns skillnader i män och kvinnors smärttröskel och smärttolerans, samt om skattningen av den upplevda smärtan skiljer sig mellan könen. En inriktning mot akut fysisk smärta har gjorts i detta arbete. Arbetet har utförts som en litteraturstudie som använt sig av databassökning för att inskaffa det vetenskapliga materialet.
