Trädens utveckling efter att de har lämnats som naturhänsyn : tillväxt, mortalitet och strukturell förändring 6-18 år efter avverkning

Today green tree retention, together with leaving dead wood, is a common practice with the aim to reduce negative impacts on biodiversity and environment due to clear-felling. To better understand whether this conservation practice also makes a long-term difference, it is important to know what happens to these trees after harvest. Few studies have made an assessment of what happens to retention trees over a longer time period. In this study I inventoried retention trees that were left at clear-cuts six, twelve and eighteen years ago. I carried out a re-inventory of 57 retention patches (divided into free-standing tree groups, small swamp forests and edge zones) and free standing dead trees, spread over 25 previous clear-cuts in central Sweden.

Kyla i Nyköping och Motala : Kartläggning av kylapotential för Vattenfall Värm

The Swedish energy company Vattenfall is currently the owner of the district heatingsystems in Nyköping and Motala. To be able to also offer cooling solutions tocustomers are becoming more and more important. This report describes the resultsof an investigation of the cooling market in the two cities and the potential needs forcooling today and in the coming 20 years. The total potential for the coming 20 yearsis estimated to be roughly 17 MW for Nyköping and 9 MW for Motala.Two possible district cooling systems for each of the two city centers was modeledand a comparison was made between different cooling techniques namely absorptionand compressor chillers.Absorption chillers driven with district heating during the summer is one way ofincreasing the load in a combined heat and power plant and thereby the possibleelectricity generation. The cost of heat production must be low for absorption chillerto be able to compete as an alternative.

Löpmagsförskjutning hos mjölkkor : en besättningsutredning för att identifiera riskfaktorer för metaboliska störningar

The purpose of this study was to find possible explanations to why the studied herd had an increased incidence of abomasal displacements. The incidence of abomasal displacement in the herd was three times higher than the incidence of an average Swedish herd. The cows in this study were fed a total mixed ration. The different parameters studied were: energy content in food, nutritional content in food, body condition scoring, concomitant other diseases, and blood parameters of glucose, fructosamine, cholesterol, insulin, betahydroxybutyrat and free fatty acids. The author?s suggestions to decrease the problems are to decrease the energy content in the TMR to lower the cows? body condition scores in the dry period and changing the content in the TMR to increase the amount of NDF and adding structure in the form of chopped straw.

Inverkan av leasingklassificering på konkursrisk - en studie av hur redovisningsbaserade prediktionsmodeller påverkas av en ny leasingstandard

The purpose of this bachelor-thesis is to investigate the possible effects of lease accounting on the estimation of bankruptcy. This is done by estimating the risk via prediction models based on accounting ratios for a sample of 43 listed firms in Sweden. Estimation is conducted twice for each firm, once base on unadjusted data as it is presented in the annual report of 2012, and one with data adjusted for operational leases (that is data is treated as if all leases present were to have been reported as financial leases). In the next step it is tested weather the predictive ability of the models is affected by this adjustment or not. For this purpose translation of bankruptcy risk into synthetic credit ratings via interest coverage ratios is done.

Födoval hos juvenil piggvar (Psetta Maxima) : effekter av bytesstorlek

The effects of prey size on prey choice in different cohorts of juvenile turbot (Psetta maxima)were studied in three nursery areas at Gotland. Prey length measurements showed that gobies(Gobiidae) increased in average length during the season, while mysids (Mysidae) did not.Experiments on predation capacity of different size classes of turbot on different size classesof prey showed that juvenile turbot easily can eat gobies that are up to two thirds of their ownbody length, while the body size of turbot does not have any effect on the predation capacityon mysids. Stomach content of 217 turbots, less or equal 35 mm, was analysed to see if therewas any change in diet during the season, but there was no significant change in diet. Theoverall conclusion was that early settlers most likely have an advantage due to greater accessof alternative prey..

Urshults Knektar : En studie om vad som hände de indelta knektarna från Urshults rotar 1709 till 1718

This essay examines what happened to soldiers from Urshult in military service of Sweden during the diminished power of the country in the beginning of the eighteen century.

Det energiproducerande huset

We are heading towards a huge switch of how energy is produced with fossil fuels being replaced by renewable energy sources. It is not difficult to replace the energy you use in the house and there is no need for futuristic technology. There are already many established products on the market such as high efficiency vacuum solar collectors, heat pumps & small wind power stations that can supply the energy being used in a house. The company Sol & Energiteknik SE AB in Huskvarna has many different products which can reduce the need for an outside energy distributor. An average house in Sweden uses 15 000 kWh for heating, 5000 kWh for tap water and 5000 kWh for electricity.

Likabehandling : Men på vilka grunder?

The Act Prohibiting Discrimination and Other Degrading Treatment of Children and School Students (2006:67) entered into force on 1 of April 2006. The purpose of this Act is to promote equal rights for children and school students and to combat discrimination on the five discrimination grounds of sex, ethnic origin, religion or other belief, sexual orientation or disability.

Discrimination is a result of the social norms which tends to exclude people who does not fit in and therefore considerers as being abnormal.

Zenbuddhistiska meditationsträdgårdar - för ökat välbefinnande i Sverige

This paper is intended to provide a picture of which associations water can wake in the human mind from the perspectives of garden history as well as from that of environmental psychology. I hope to paint a fairly broad picture of our perception of water that can serve as a basis for discussion and as a starting point for different forms of design work in landscape architecture. The historical perspective emphasizes the importance of water as a condition for the emergence of gardens and in a wider perspective the importance of water in early cultures. Also, I describe a picture of how water has been used throughout the history of gardens from early Egypt to the baroque era. The garden history analyzed from an art historical perspective gives a picture of human associations to water, and the history behind these associations is presented. As a compliment to the art history approach, I have chosen to highlight our associations with water from the perspectives of environmental psychology and evolutionary science.

Har börsen fått influensan? - En event-studie av huruvuda fågelinfluensan har påverkat finansiella marknader

SYFTE - Uppsatsens syfte är att undersöka huruvida uttalanden från Världshälsoorganisationen, gällande första händelsen av att vild¬fågel, hönsfågel eller människa blivit smittad av H5N1-viruset i ett land, har bidragit till abnormala prisrörelser hos aktuellt lands noterade företag med hönsfågelrelaterad verksamhet.METOD - Undersökningen är en event-studie där aktiekursers utveckling har undersökts vid informationshändelser rörande fågelinfluen¬san. För att estimera en jämförande normal avkastning har vi använt en kombinerad OLS- och ARMA-modellering.TEORETISKT PERSPEKTIV - Den effektiva marknadshypotesen är den grundläggande teorin som använts för att analysera insamlad empiri, som tillsammans med andra event-studier utgör det teoretiska ramverket.EMPIRI - 19 informationshändelsers påverkan på aktiekurser har analyse¬rats för att estimera normal och abnormal avkastning. Dessa 19 aktiekurser härstammar från 18 företag, belägna i sju länder.SLUTSATSER - Undersökningens resultat tyder på att undersökta företags aktie¬priser inte påverkats nämnvärt av Världshälsoorganisationens uttalande om att H5N1-viruset spritt sig till respektive företags land. Det finns dock ingen möjlighet att dra några statistiskt sig¬nifikanta slut¬satser grundade på undersökningen och dess analy¬serade empiri..

Företagsförvärv : En studie om förvärvsmetodens betydelse för de uppköpande företagen

Denna uppsats utgörs av en jämförande studie vars mål var att utröna huruvida åtta stycken utvalda investmentbolag på Stockholmsbörsen hade varit ett konkurrenskraftigt alternativ som sparform eller inte med avseende på risk och avkastning. Detta jämfört med SIX Return Index och den riskfria räntan under en tidsperiod på tio år, 2001-01-01 till 2010-12-31.Syftet med undersökningen var att den i slutändan skulle mynna ut i generella slutsatser kring investmentbolag som sparform utifrån de data som hämtats in från de berörda investmentbolagens hemsidor.Författarna kunde efter avslutad undersökning dra slutsatsen att investmentbolagen historiskt sett hade klarat sig mycket bra och kunnat uppvisa resultat som varken marknaden eller den riskfria räntan var i närheten av. Även om vissa av investmentbolagen hade presterat sämre än jämförelsemåtten så var dock den samlade bilden att de som grupp hade varit ett mycket fördelaktigt investeringsalternativ. Detta med en genomsnittlig totalavkastning som överträffade index med drygt åtta procent.  .

Konsulters arbete med nyttovärdering vid ERP-investeringar : En fallstudie

Studiens syfte är att undersöka hur konsulter arbetar med nyttovärdering vid ERPinvesteringar,samt finna kritiska framgångsfaktorer som kan fungera som stöd för ERPkonsulter.Vi har genomfört en fallstudie på SYSteam Anderstorp där vi på ett kvalitativt vissamlat in data via dokumentundersökningar, observationer och intervjuer. Vid analys avinsamlad data kunde vi identifiera fem steg en ERP-konsult bör gå igenom för att värderanyttor vid ERP-investeringar. Dessa steg är 1processkartläggning, 2identifiering av nyttor,3värdering av nyttor, 4genomförande och 5uppföljning. Vidare har vi i varje steg kunnatidentifiera kritiska framgångsfaktorer som vi anser kan underlätta en ERP-konsults arbetemed nyttovärdering. Sammanlagt har vi kunnat identifiera fjorton kritiska framgångsfaktorer.De slutsatser vi kunnat dra av denna studie är att befintliga modeller för nyttovärdering ochvärdehemtagning tenderar att bli för teoretiska för att kunna tillämpas i praktiken.

I skuggan av friheten : Upplevelser av att bryta upp från en hederskontext

So called honour based violence is a present problem in Sweden. Although recently there has been a steadily growing political and academic awareness around so called honour based violence, there are still problems in the face to face meeting with the victims. This dissertation contributes to the understanding of these victims. The empirical material is based on five young women's stories about growing up in a context of 'honour' and their experiences from breaking up from this context.  My ambition is letting these stories be heard and told as to lead to an increasing understanding of how these women experience themselves and their surrounding society. The purpose of this dissertation is to illustrate how young women interpret their self in the light of a separation from their families.
