Effekten av metyljasmonat som skydd mot gnag av snytbagge (Hylobius abietis) på gran- och tallplantor :
The effect of methyl jasmonate on resistance against the large pine weevil (Hylobius abietis) in Scots pine and Norway spruce seedlings.
A field experiment was conducted in order to determine the dose-response effects of methyl jasmonate (MJ) on growth and defence to pine weevils in Scots pine (Pinus sylvestris) and Norway spruce (Picea abies) and to compare the effect of MJ between pine and spruce.
In addition a complementary greenhouse experiment was conducted with the same aims as above and to determine the amount of resin ducts and their correlation to the feeding of pine weevils.
The field experiment was conducted on a fresh clear cutting in Garpenberg, southern Dalarna in central Sweden. The experiment consisted of 30 blocks with three kinds of containerized seedlings: 2-year old spruce, small pine (before shoot elongation) and 1-year old pine (already shoot elongated). They were all exposed to 4 treatments 14 days prior to the experiment: control, 25 mM/L MJ, 50 mM/L MJ and 100 mM/L MJ. Data on weevil damage and seedling growth were collected after the first and the second growing season.
The seedlings in the greenhouse experiment were of the same kind and were exposed to the same treatment as the ones in the field experiment.
Jämförelse av metoder för malwareanalys
Att genomföra analys av malware är en viktig del i att få en bättre förståelse för hur det fungerar och beter sig när det drabbar ett system. Själva genomförandet av analysen kan göras på olika vis. Detta arbete tittar närmare på tre metoder för att analysera malware och ser vilken information de ger. Genom de experiment som utförs på ett malware som går under namnet BetaBot skapas en bättre förståelse för hur just detta malware fungerar. Målet är bland annat att jämföra de olika analysmetoder som valts ut och se hur de förhåller sig till varandra.
Analys av ljudspektroskopisignaler med artificiella neurala eller bayesiska nätverk
Vid analys av fluider med akustisk spektroskopi finns ett behov av att finna multivariata metoder för att utifrån akustiska spektra prediktera storheter såsom viskositet och densitet. Användning av artificiella neurala nätverk och bayesiska nätverk för detta syfte utreds genom teoretiska och praktiska undersökningar. Förbehandling och uppdelning av data samt en handfull linjära och olinjära multivariata analysmetoder beskrivs och implementeras. Prediktionsfelen för de olika metoderna jämförs och PLS (Partial Least Squares) framstår som den starkaste kandidaten för att prediktera de sökta storheterna..

Text i tolkning : Berättarteknisk analys av Carl Jonas Love Almqvists Drottningens juvelsmycke
Syftet med den här uppsatsen var att göra en berättarteknisk analys av Almqvists roman Drottningens juvelsmycke. Jag har i denna analys utgått från de begrepp som Gérard Genette presenterar i sin bok Narrative discourse och provat om de kan beskriva berättartekniken i Drottningens juvelsmycke. Jag har i uppsatsen också, ganska kortfattat, tagit upp en del andra aspekter av boken. Bland annat har jag berört romanens huvudkaraktär Tintomara, bokens genre och bokens grundläggande tema.Det jag har kommit fram till är att Drottningens juvelsmycke uppvisar en mycket komplex berättarteknik. Ett av de mest uppenbara och intressanta greppen i boken är blandningen av episk och dramatisk framställningsform.
Allmänsjuksköterskans kunskap och attityd gentemot patienter med HIV/AIDS
The aim of this study was to examine nurses knowledge and attitude towards HIV/AIDS patients over the world. A descriptive literature study has been made based on scientific articles from the databases PubMed and Cinahl. The authors have examined the sampling and the falling off of the articles. The result shows that the attitude towards HIV patients is different from one country to another. The attitude was affected by several of factors such as experience, fear, knowledge / education and the nurses attitude and willingness to care for these patients.
Dagens Nyheters tryckeri: En jämförande tvåfallsstudie av företaget och makten
This study is an institutional analysis of the firm both as it is theoretically conceptualized and how it takes shape and changes. The role of power relations between manage¬ment and employees is especially examined with the aim of evaluating pos¬sible connections between the firm as an institution and power relations within it. Based on a comparison of two cases (two selected periods of the same organization) it asks ?How closely does each case match the conceptual characteristics of the firm??; ?What are the power relations between management and employees in each case??; and finally ?What factors account for the resulting differences??. It is found that there is a negative correlation between employee power and proximity to the firm as a concept.
En retrospektiv fallstudie av konservativ behandling av intraartikulära hovbensfrakturer, typ II och III, hos rid- och körhästar :
Hospital records of 32 non-racehorses referred to Skara Animal Hospital and Halland Animal Hospital, Sweden, between January 1995 and September 2001 for intraarticular fractures of the third phalanx, were reviewed, and follow-up information on final outcome was collected to determine whether any injury or treatment factors could be associated with the outcome. Mean age of the horses was 8.3 years (range, 1-20 years), and follow-up time ranged from 1 to 7 years after injury. In 11 (34%) of the horses, injury involved the front limbs. Twenty-two (69%) horses returned to their original level of use. There was no statistically significant correlation between outcome and elapsed time from injury to treatment, treatment variables, or bony union in the present study.
Vinster med björkinblandning i granbestånd i syfte att höja markens pH-värde
The soil acidification and the pH-value of the soil have been discussed for many years. Many observations of the tree species effects on the soil pH have been done.
We have discussed the effects on the soil surface pH-value with a birch (Betula spp. L.) admixture in Norway spruce stands (Picea abies L.).We have used data from the Swedish National Forest Inventory. We have also discussed how the wood production and the biodiversity can be increased in mixed stands, in according to the Swedish forestry act Skogsvårdslagen. Our sampling areas are located in Norrland, Sweden.
The results show a significant correlation between an increased birch admixture and an increased pH-value of the soil.
Forskning och nya läromedel : en analys av SFI-boken LÄS! Kurs B och C
Den senaste forskningen inom svenska som andraspråk förespråkar genrepedagogik, för att eleverna bättre ska förstå vad språket gör för arbete åt oss, beroende på val av genre. Detta skapar en större språklig medvetenhet hos eleverna. Som metod för att nå genre- kompetens används cirkelmodellen, vilket gynnar ett sociokonstruktivistiskt lärande i klassrummet. För att som lärare lättare kunna anamma de senaste rönen inom forsk- ningen skulle det vara önskvärt om läromedelsförfattare också tog ett mer tydligt avstamp i både forskning och kursplanernas krav på språkkompetens. Den här under- sökningen är en analys av ett läromedel för sfi kurs B och C ur ett genrepedagogiskt perspektiv och en analys av kursplanen för läs och skriv inom C-kursen.
Barns delaktighet i frågor om umgängesstöd : en studie av elva tingsrättsdomar
The purpose of this study was to examine children's participation in court proceedings on supervised visitation and to analyse the descriptions of children in court verdicts. Eleven verdicts concerning supervised visitation resolved in 2014 were collected from two district courts in Stockholm County and studied with a qualitative textual analysis. The material was analysed with participation levels influenced by the ladder of participation for children developed by Roger Hart and with the theory of sociology of childhood. Our findings showed that children's opinions were mentioned in eight of the verdicts. In four verdicts the children's will influenced the courts decisions.
Informationsasymmetri och redovisning till verkligt värde - en studie av nordiska fastighetsföretag
This thesis aims to investigate the information effects of fair value accounting in Nordic real estate companies. As a consequence of the mandatory IFRS adoption in the European Union in 2005, listed Nordic companies are allowed to recognize investment property at fair value in accordance with IAS 40. Theory suggests that fair value accounting should lower information asymmetry. Therefore, this study aims to examine correlation between fair value accounting of investment property and information asymmetry on the stock market. To investigate this, we use bid-ask spread as a proxy for information asymmetry and examine Nordic real estate companies before and after the implementation of IFRS.
Full Circle: upstream and downstream migration of Atlantic salmon (Salmo salar) in the northern Swedish river Vindelälven
The life cycle of the anadromous Atlantic salmon (Salmo salar) can span large geographic, political, and socio-economic boundaries. Management strategies and regulations that only concentrate on small spatial scales often overlook larger basin-wide problems, especially relating to post-spawn seaward migration. In this master thesis one entire migration cycle of wild adult Atlantic salmon in the unregulated northern Swedish river Vindelälven was monitored by radio-telemetry tracking during upstream spawning migration and downstream seaward migration back to the Baltic Sea. The effect of ladder passage variables (time to pass, total time in the ladder, passage day over the ladder) at a fish ladder downstream in the river Umeälven, as well as fish size, were evaluated to determine if differences in upstream migration distance in the river Vindelälven could be observed. Ladder passage variables did not affect migration distance, but size exhibited a negative relationship to migration distance.
Elasticitetsmodulen i en kalkstabiliserad vägterrass : en fältstudie
Stabilization of subgrade is an internationally common technique to improve the characteristics of a soft soil. Improving the stiffness and bearing capacity of the subgrade enables the pavement to be designed with reduced depths of subbase and basecourse aggregates. This makes the stabilization technique both economically and environmentally interesting. Both natural and stabilized soils have high inherent property variability that should be considered when the characteristic value is derived. By analyzing the spatial variability in stabilized and natural subgrades it is possible get the parameters needed for reliability?based modeling of soil properties.
Revisorns roll i familjeföretaget : företagarnas perspektiv
The purpose of this study explains the relationship between corporate governance and the auditor's role in Swedish family firms with the definitions micro, small and medium sized enterprises (SMEs) and how this relationship is affected by the firms strategy. The study is based on a survey sent out to 3000 Swedish SMEs, of which 280 responses from family firms could be used. Our findings showed that the auditor in the family firms didn?t have a specific role or contributed added value to the firm, and that the strategy didn?t affect the outcome. Furthermore, we found correlation between the perceptions of the auditor's role and added value depending on the family firms type of corporate governance.
