Metod för inventering av underhållsbehov för skogsdiken
Large areas have been ditched in Sweden during the past 100 years to improve the forest production. Ditching and also maintenance of old ditches are operations having mainly negative effects on water quality, flora and fauna and changing characteristics of soil. The purpose of this study was to suggest a method for inventory of the need for ditching maintenance in old forest ditches that takes biodiversity, water protection and forest production into consideration. Inventory methods from five Swedish and Finnish forest companies, agencies and organisations were compared. Their employees were interviewed about their handling with ditches, forest production and nature conservation.

The study reviews twelve scientific articles that have been processed from the aim of the study. The result shows six therapy options, Er:YAG laser, air abrasive, ultrasonic device, hand instruments, hand instruments in combination with antibiotics and hand instruments in combination with clorhexidin. The following methods are described according to how they are used and how they affect the soft tissue surrounding dental implants.
Effects of palmitic and stearic acids supplementation on milk yield, composition and milk lipolysis in dairy cows
When facing the fact that high yielding dairy cows has an increasing energy requirements, the practice of adding lipid supplements such as concentrates rich in palm oil and/or palm oil industry by-products become more common. Palm oil containing high levels of C16:0 causes high levels of free fatty acids (FFA) which are linked to larger milk fat globules (MFG) which affect the reaction of lipolysis resulting in rancid flavour and processing problems. Instead of using palm oil, rapeseed oil rich in C18:1 C18:2 can be used. In order to evaluate the effect of
added C18:0 and C16:0 on milk lipolysis, 30 Swedish Red lactating dairy cows including 15 multiparous (MP) and 15 primiparous (PP) cows were randomly divided in three groups
resulting in 3 10 cow-groups (5 PP and 5 MP cows per group) and fed one out of three concentrate mixtures: control (C), a standard concentrate mixture with no fat added; palmitate
(P) as C plus the addition of palmitate methyl ester (10 % in DM basis); and stearate (St) as C plus the addition of stearate methyl ester (10 % in DM basis). Milk yield was registered, and milk samples were collected and analysed for milk composition, FFA content and size of MFG.
Assessing the ability of LARGE overexpression to prevent the development of muscular dystrophy
Duchenne Muscular Dystrophy (DMD) is a hereditary X-linked fatal disease that affects 1 in 3500 male births. It is the most common kind of muscular dystrophy in children and leads to death in the late teens or early 20s for many patients. The mdx mouse is a model of DMD that can be used to investigate experimental therapies. Overexpression of a glycosyltransferase, CT GalNAc, in mdx mice has been demonstrated to prevent the development of muscular dystrophy. Overexpression of another glycosyltransferase, LARGE, is currently being investigated as a treatment for another group of muscular dystrophies, the dystroglycanopathies.
In this study, we overexpressed LARGE in mdx mice in order to investigate its effect on the development of muscular dystrophy.
Powerplay En studie om de stora sporternas numerära överläge i svensk press
The purpose with our study was to see if and how the amount of articles regarding different sports has changed during the last three decades. If it had changed our target was to se how and why it had changed. We have performed a quantitative content analysis. In the analysis we have studied the two national Swedish newspapers Dagens Nyheter and Aftonbladet. In doing so we have created two synthetic weeks in each of the years 1986, 1999 and 2012.
En novellsamling blir till
This essay discusses my proposed collection of short stories. The aim has been to examine the texts in terms of form and thematics, and position of the texts in a social context. First I present the collection, and then look at the texts from stylistic angle. I have chosen to use the concept of descriptive style. I have picked out certain parts of my texts in order to see which effect they have on the reader (in this case I).
Trådlös överföring av styrsignaler
Anledningarna till att använda sig av en trådlös signalöverföring i en industri kan vara många, oftast handlar det om ställen där det är svårt eller omöjligt att ha en trådad förbindelse. I det här fallet är det en sedimenteringsbassäng där man tar hand om processvatten från industrin. Bassängen är utformad som en cylinder där vattnet rinner genom olika avdelningar för att minska innehållet av sediment. I bassängen cirkulerar en plattform med diverse omrörare och skrapor på. Eftersom denna del går runt hela tiden är det svårt att ha en fast förbindelse till de drifter som finns.
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.
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.
Utveckling av transmission ochtestrigg till ett vågkraftverk
Fler människor börjar använda olika mobila operativsystem i mobiltelefonen samt appar som enbart fungerar på plattformen. Det leder till att app-leverantörer måste utveckla varje app till varje specifik plattform vilket är dyrt. De vanligaste operativsystemen som används idag är Android samt IOS men hösten 2012 släpptes Windows Phone 8 vilket innebär ytterligare en plattform att ta hänsyn till. I sammarbete med företaget Sogeti Jönköping fokuserar studien på att hitta en metod som gör det möjligt att migrera appar mellan plattformar och till Windows Phone 8. Studien innefattar också att identifiera för och nackdelar med olika app-typer genom en litteraturstudie och intervjuer samt att testa om migrationsmetoderna fungerar praktisk genom en implementation.Resultatet har påvisat att det finns två stycken olika metoder för migration vilket är PhoneGap och Xamarin.
Effekt av spädningsvätska på spermiemembranintegritet analyserad med NucleoCounter SP-100 :
This study is a part of a larger project where the aim has been to evaluate different methods to assure the quality in stallion semen, due to the fact that some stallions in horse breeding have poor semen quality. The increased use of transport semen requires new methods to ensure good semen quality.
In this part of the project the viability and concentration in fresh and cooled semen was examined with NucleoCounter SP-100. A comparison between two different commercially available semen extenders, Kenney?s and INRA 96, was made.
