At Rottneros pulp mill mechanical pulp is bleached with hydrogen peroxide. The changes of bleaching chemicals that are used for different grades are taken from bleaching tables; however these tables are old and need to be updated. The purpose of this thesis was to be the basis of new documentation.In this thesis three pulps where studied with the aim to find the optimal bleaching chemical changes (total NaOH/VP-quote) for each pulp. The pulps were taken from the filter before the bleaching tower and the pulps were bleached in the lab. The most important pulp property in this study was the brightness and how that was influenced by the chemical dosages.

Birch is the dominant deciduous tree species in Sweden but only 16 % is found in pure birch stands. The majority of the birch (51 %) is to be found in conifer dominated stands. Swedish forest land comprises approximately of 23 % mixed stands and one problem is that for mixed stands there are few management recommendations. The underlying aim of this thesis was to study the management of mixed forest stands of spruce and birch to achieve good timber quality of birch. The study was based on a literature study and measurement in a field experiment launched in 1998 by the Swedish University of Agricultural Sciences (SLU).

Background: As a result of the financial markets ever ongoing product innovation a new derivative was introduced in the USA in 1997. A derivative that derived it's value, not from the price of an underlying asset, but instead from a climate factor. It's been known for a long time that revenue in certain industries are affected by weather conditions. The suppliers of weather derivatives claim that these weather sensitive businesses can user weather derivatives in order to lessen weather risk. Purpose: To do a critical evaluation of how weather derivatives can be used by companies as a risk management tool.

Husums plant has a selection of different pulp pumps at bleaching plant 4 and 5. The displacement- (HC-pump, Sund Defibrator PTD-60) and centrifugalpumps (MC-pump, MCA 42-200, MCP 30/20) are of interest in this report. The centrifugal pumps are controlled by throttle valves, which result in an energy loss. Chemical mixers are used to mix ClO2 into the pulp before proceeding into a holding tower where the bleaching process occurs.The energy demand of the different positions has been measured or calculated to be used in comparisons against new equipment. Quotations were requested and delivered from Valmet and Sulzer.

Bakgrund: Det rådande pensionssystemet i Sverige består av sex så kallade AP-fonder. Genom åren har pensionssystemet flertalet gånger kritiserats för dess låga avkastning.Problem: Vår huvudfråga är att jämföra AP-fondernas risk och avkastning med aktiemarknaden som helhet, detta ska ske med hjälp av två jämförelseindex: MSCI World och SIXRX.Syfte: Syftet med uppsatsen är att jämföra de fyra första AP-fondernas risk och avkastning med aktiemarknaden som helhet under åren 2002-2010.Metod: Vi har använt oss av en kvantitativ metod, genom att samla in information från AP-fondernas årsredovisningar och hemsidor. Vi har samlat in historisk data, som vi sedan har bearbetat och analyserat.Slutsats: De studerade AP-fonderna har presterat sämre än aktiemarknaden..

The purpose of this risk analysis is to investigate if the transport of dangerous gods through Halmstad is a threat to the surrounding area. The report shall serve as a component in the making of pre-plans and the planning of exercises..

This report concerns the for Sweden foreign tree species hybrid larch, hybrid aspen and poplar, and focuses on the area Kalmar and Mönsterås municipalities. The report shows that there are not only advantages with these species. The larch, the most common of the alien tree species has the greatest problems due to that its timber is difficult to sell in the area but also the Larch´s poor pulp quality and is more likely to be damaged by wildlife than the spruce is. Hybrid Aspen is much easier to sell and is used like regular aspen for match wood and textile pulp. Its disadvantage is the high cost for plants and to prevent damage from wildlife.

Studien syftar till att belysa finanskrisens reella påverkan på företagens finansiella riskhantering. Läsaren ska också få en ökad förståelse för hur ett mindre antal svenska företag hanterar sin finansiella risk och hur denna hantering måhända har förändrats.I denna studie har det framkommit att företag både i Kalmar, Emmaboda och Borås inte i någon större utsträckning påverkats av den finansiella krisen som rådde mellan 2007-2010. Det som har skett i två av företagen är en ökad intern kontroll och ökad krav vad gäller kontroll av kontroller för att på så vis minimera risk för företagets intressenter. Således har en viss påverkan skett som följd av finanskrisen och arbetet med riskhantering för ett urval av företag i Sverige.Respondenternas inställning till finanskrisens 2007-2010 påverkan har varit att de inte har förändrat sitt dagliga arbete nämnvärt som följd av krisen..

This thesis is about the effects of fertilizing and thinning on furniture timber from redwood. Interviews of furniture manufactures have been made and observing of timber from the Swedish fertilizing and thinning trails. The result from the interviews showed which properties that is important for the furniture manufactures and then the result from the observation showed which type of management of the forest that gave the most timber that had those properties. .

The purpose of the study was to investigate the use and losses of energy in an existing older building. Another purpose was also to look through various options for heating systems with renewable energy in the building. The aim was to reduce the use and losses of energy. The first step was to study the related electricity bills of the building and also perform measurements and calculations of the building envelope and ventilation. The next step was to find out the possible actions for energy saving by performing measurements and calculations.

Looking at the debate on nuclear power in Sweden, the issue of risk is central to understanding the difficulties in resolving differences between proponents and opponents. I sought to answer the research question: "how is the concept of risk constructed in the nuclear power debate in Sweden?" Four main aspects of risk construction were defined and investigated to identify differences between sides in the debate. Through a qualitative study of the debate and its actors I found clear differences in respect to all four aspects of risk construction. First, the perception of nuclear power as a "normal risk" is common among nuclear opponents in contrast to a largely probabilistic view among proponents.

Bakgrund: Hand i hand med dagens ökad fokus på risk har intresset ökat för ettriskhanteringskoncept som kallas Enterprise Risk Management (ERM). Tanken medmodellen är att hantera risk övergripande istället för isolerat på separata områden iföretaget. De största fördelarna med modellen sägs vara bättre beslutsfattande inomorganisationen, att riskmedvetenheten ökar och att intressenter får bättre förtroendeför företaget.Syfte: Syftet med denna uppsats är att jämföra den teoribildning om ERM som växerfram med praktisk erfarenhet från icke-finansiella företag som implementeratmodellen. Målet är också att skapa förståelse för både för- och nackdelar medmodellen.Avgränsning: Undersökningen har inriktats på icke-finansiella företag eftersom färrestudier har gjorts inom området.Metod: En kvalitativ fallstudie av två icke-finansiella företag har genomförts med enabduktiv ansats och en blandning av explorativ och deskriptiv design.Resultat: Undersökningen visar att ERM skapar vissa positiva effekter för företagenmen också att en del problemområden har identifierats. De begränsningar i modellensom uppstår anses vara nära relaterat till svårigheten med att hantera mjuka risker ochproblemet med att ERM kan bidra med för stor passivitet i verksamheten dåminimering av risk blir mer omfattande.

The purpose of the thesis has been to explore the use of hedge fund styles when constructing portfolios of hedge funds (i.e. funds of hedge funds). The central question is if the use of hedge fund styles can significantly explain and improve risk adjusted returns (characterized by Sharpe ratios). The study has been done in collaboration with Optimized Portfolio Management AB who desire further knowledge and evaluation of hedge fund styles for their fund of hedge funds.To be able to create successful ex ante portfolios we have explored various prediction models for both risk and return. Our findings indicate that return prediction is problematic using simple models such as regression since the risk exposure of the indices appear to change significantly over time.

This review paper summaries scientific research about horse thermoregulation and the consequences of using a blanket. Horse owners put blankets on their horses to protect them when they are clipped, to protect them from bugs, to keep them clean and so on. This can have consequences for the horse which their owners might be unaware of. I have tried to answer following questions by searching the available scientific literature; ? How can the horse maintain thermoregulation? ? Is there a risk of suffering when horses wear a blanket? ? Is there a risk of suffering when horses do not wear a blanket? ? How can animal inspectors estimate the welfare of horses when they wear or do not wear a blanket? My result shows that horses who wear a blanket have an increased risk of becoming overheated, develop a chafing, have an increased exposure hazard and have a restrained natural behaviour.

Abstract Over the years the consciousness of risk has grown. It?s hard to influence risks, therefore there are guidelines stating that significant risk must be included in the annual report. This paper is a case study; the purpose was to examine how four Swedish listed companies chose to disclose their internal and external risks. Risk is initially described in general sense and then it figures to what constitutes an economic risk.Through a case study of four Swedish listed companies? annual reports we have, through qualitative methods found how the companies chose to disclosure their risks.
