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.

Kolbalansen vid olika skötselstrategier för skogen på Tagels fastighet.

Since the 19th century the concentration of CO2 in the atmosphere hasincreased by 40 percent as an effect of the use of fossil energy sources.Increased concentration of CO2 will likely lead to increased temperature,changes in precipitation, rising sea level and increased frequency of extremeweather like storm events. A step to reduce emissions of CO2 and mitigateclimate change, for the property of Tagel, can be to adopt new silviculturalstrategies and analyse which is the most effective. As a result of that, threescenarios was produced, business-as-usual (BAU), increased set aside landand energy. An introduction of windpower at Tagels estate (property) andeffects on carbon balance was also examined. By using the Heureka systemand LCA-analysis in this study, it showed that the scenario of increased setaside land was the most efficient way to reduce carbon dioxide (CO2)emissions for the analysed period of 100 years.

Holländska sjukan En litteraturstudie om effekterna av holländska sjukan på Botswanas textil- och boskapsindustri.

Botswanas ekonomiska tillväxt utgör ett sällsynt exempel på ett afrikanskt land som har lyckats använda sina naturtillgångar till att driva på en ekonomisk utveckling och samtidigt minimerat effekterna av den så kallade Holländska sjukan (HS). HS är ett ekonomiskt fenomen som går ut på att en växande sektor som baseras på naturtillgångar skadar landets tillverkningssektor och leder därmed till en indirekt de-industrialisering. Botswanas diamantindustri står för drygt 35% av BNP:n och hela 75% av exportintäkterna vilket gör att landet har en mineralbaserad ekonomi. Detta faktum har gjort landet väldigt intressant för forskning. Aktuell forskning har med hjälp av ekonometriska metoder visat att landets tillverkningssektor har undvikit eller drabbats minimalt av de effekter som HS utgör.

Kundrelationer och Kundlönsamhetsbedömningar: En fallstudie inom telekom

This paper examines the customer relationships of a telecom operator and how their customer accounting is done. The aim is to use the framework developed by Lind & Strömsten (2006) to categorize customer relationships and see to what extent the framework predicts which type of customer accounting method is used for each customer relationship. A case study was made at Telenor Sverige AB where different customer relationships are identified and linked to the customer accounting techniques that are used for financial measurement of the customers. Findings include that all but one of the customer relationships described in the framework were recognized at Telenor and that most customer accounting techniques mentioned in the framework were in fact used and associated with different customer relationships. The results of the case study also highlight that some differences exist between the predictions of the framework and the observations at Telenor..

Local poultry production in rural Zambia and the effect of light on poultry performance

Zambia is a country in Southern Africa where poverty is widespread and the traditional keeping of local poultry therefore plays a crucial role in improving nutrition. Meat and eggs from poultry are important sources of protein but also of income. Improving the poultry production is thereby a method to fight poverty. For poultry, the access to light is an important factor for both growth and egg production. In this paper, the focus is on the traditional village chickens used for both egg and meat production, how they are kept, their health and welfare and if the use of a solar lamp will influence their behaviour, growth and egg production. Three studies were conducted in Chibombo and Choma Districts in Zambia were 17 farmers were interviewed regarding the village chicken management of which six farmers participated in a solar lamp experiment.

Effekterna ligger i betraktarens ögon - En studie om effekter av videopresentationer inom e-handeln

Companies within the e-commerce industry currently try to overcome the disadvantages of not being able to provide a physical inspection of products, and this is especially an issue for the apparel industry. One way of trying to overcome this issue is by presenting apparel with a short video of a model wearing the garment. The aim in this thesis is to investigate how these video presentations affect consumers' emotions, cognitions and intentions. Since previous studies have found that different shopping scenarios can moderate the effect of stimuli in the atmosphere on the consumers' emotions, we also aim to see if a video presentation, depending on the shopping scenario, could have a negative impact on site visitors. Moreover this thesis investigates the moderating effects of involvement on consumers' cognitions.

Jämställdhets- och föräldraledighetsregler : -regelverkens samverkande effekt för ett jämställt arbetsliv

The legal right to take time off from work to care for one`s children has been regulated in Swedish law since late 1930. This right was limited to mothers and was provided under restricted forms. There was a long qualification period and the length of parental leave was limited.Since then, the right to parental leave has been extended through several modifications of the law. The question of equality in both the labour market and the private sector has been one of the greatest forces behind these changes. By including men in the right to take parental leave, the work place has become more equal and it is now considered a natural part of the employee?s life to request time off to care for children.Labour Arbitration Court has shown through its case law that equality in the work place is of the utmost importance and has shown its support in this matter through its judgements.

Naturreservat : en bra naturvårdsåtgärd för att bevara enskilda arter och/eller bevara den biologiska mångfalden?

The examination of the adequate nature conservation methods in a natural reserve, to conserve a specific species and / or increase biological diversity is the subject of this study. This work is based on four species, that can be found during the Spring season, liverleaf, wood anemone, brimstone and woodpecker. The incidence and availability is studied and closely observed for these species in twenty forests, i.e. ten forests which are nature reserves and ten forests with the similar characteristics as the nature reserves habitat, but are not nature reserves in Gnesta mucipality, Södermanland. Measurements of the tree crown and the diameter of the tree trunks where noted to study how these factors could affect the outcome of the abundance and incidence of the four species.

Uppföljning av EcoDrivingutbildning

On a request from the water sewage plant Gryaab in Gothenburg a power quality survey wasperformed. The voltages and currents have continuously been sampled in the incoming 10 kVsubstation HSP01 from April-August 2008. Power quality measurements were also performedin Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of theinduction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps tothe plant. The reason for the latter measurement was due to registered negative transients eachtime the motor was connected to the grid. The cause of the transients could be explained by thecoupling in the substation, the ageing of the motor which could result in damage of thebearings or resonance in the motor circuit which amplifies high frequency harmonics.

Sociala och emotionella interventioner i skolans värld. : Vad händer med karaktären hos eleverna?

The purpose was to investigate whether using two type of interventions (i.e., Four rooms of change in school and EQ- workshop) in addition to curriculum guidelines can affect character development in children 10-12 years of age. The data was collected using the test Junior Temperament and Character Inventory (J-TCI; Cloninger, CR, 1994) in three elementary schools among students in fifth grade who had been involved in any of the two interventions for the past two years or no intervention at all.The J-TCI scales were used to, besides the seven personality dimension it measures, create a self-constructed empathy scale. A total of 55 participants were included in the study (girls n = 26 and boys n = 29). Statistical testing with MANOVA showed no significant main effect on empathy or any personality trait. There was however an interaction effect between intervention and gender on the character traits.

Örter som fodertillskott till häst : populärt komplement utan risker?

In the Swedish market, there is a wide selection of herbs as supplement to the horse´s feed. A trend today is that many companies are marketing herbal remedies with allegations of medical effects. If you want to sell the product for that purpose it must be verified and approved as drug or natural remedy by the Medical Products Agency. Some herbs may contain active substances. Nevertheless, only a few studies have been conducted on single herbs to investigate safe doses for horses.

Vikten av ett välskött arbetsklimat: En kvantitativ studie av arbetsklimatets påverkan på ekonomiskt resultat

The well-being of employees has become a key concept in the rhetoric of the company boards and business literature of today. There is however not much statistic evidence of a connection between economic results and the perceived working climate. This thesis sets out to investigate whether there is a positive correlation between economic results and working climate on a work group level. It also aims to study which specific working climate factors influence the results. In order to meet its purpose this thesis analyzes employee satisfaction questionnaire data and economic results from more than 300 work groups.

Automobike: en cykel med aktiv balans

During spring 2012, six students at the Royal Institute of Technology in Stockholm carried out agroup project in the field of mechatronics as part of the thesis for the bachelor degree. The resultwas a robot with active balancing and the purpose of this report is to describe the development,manufacturing and problems that arose during the project. The finished robot has two wheelsmounted in line with each other, like a bicycle. Measurement data from an accelerometer and agyroscope are used together in a complementary filter for determining the angle from the verticalplane. For balancing, a PID controller was used to control the rotation of a reaction wheel, whenaccelerating causes a straightening torque.
