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.

The objective of this work was to introduce measures to reduce energy and water demand at Gävle Söder 17:10. To succeed, this energy audit has been made. The work is based on collected statistics from the property owner Norrporten, measurements, literature review and through consultation with experts in the field. Two models, one for each building, have been created in the simulation program BV2 to estimate the potential of energy measures based on the collected information. The models in BV2 have been verified against the statistics of the energy consumption.With the help of calculations and simulations, seven cost-effective measures have been identified.

This master thesis was initiated with the aim to answer at what level of installed capacity of wind power in the northern parts of Sweden it would be beneficial to improve the transmission capacity from the northern Sweden. During the process of this work the aim has changed to try and create a model that can be used to analyze how well the hydro power installed in the northern Sweden can even out the quick changes in wind power production.To create a good model of all hydro power in northern Sweden is a very large job, unfortunately too large for a master thesis. This report therefore ends with an extensive analysis of the simplifications that have been made and their effects as well as a list of the future work that has to be done.The model that has been created have shown to be effective and produce good results. The conclusions that can be made is that the northern Swedish hydro power have very good possibilities to balance the wind power production. Only a few cases where water have been spilled even though there has been some free capacity has been discovered.

The aim of this study was to evaluate the effects on a simulated wastewater plant regarding GHG emissions and use of energy and resources when implementing source separated wastewater systems. The effects were studied for different restrictions of effluent quality and for different temperatures on the influent. The simulation model BSM2G calibrated for Käppala wastewater treatment plant was used. The task was executed by simulating nine different scenarios with an increase in influent load from new connections equivalent to 3, 10 and 30 % of the present connections. These new connections were served by conventional, urine separated or black water separated systems.

A pavement construction designed to cope with the different type of traffic loads; it is exposed to and at the same time it can resist the effect of the climate. A road structure consists of sub- and superstructure which is divided by a boundary known as terrace. During the construction of unbound layers (base course and sub-base course) in the superstructure, it is always ensured that the material meet the requirements for bearing capacity and the degree of compaction. These parameters are controlled by various laboratory tests and control methods. To obtain increased knowledge of the material and improve the quality of the compaction in the field, it is necessary to perform laboratory tests in order to determine material properties.A base course material 0/ 32 mm limestone from Gotland (Hejdeby) was investigated in this study.

Till följd av Vattenfalls uppmärksammade investeringar i fossilbränslebaserad energiverksamhet har vi genom att analysera den riksdagspolitiska debatten kring Vattenfall, sökt efter återkommande yttranden, genom vilka vi  konstruerat diskurser som står för vad riksdagspolitiska aktörer anser i frågan om det statliga styret av Vattenfall. Vi kommer fram till att det inte helt oväntat går att skapa två övergripande diskurser, där de olika politiska blocken verkar inom varsin diskurs i frågan om hur Vattenfalls miljöintentioner ska uppnås..

The aim of this paper is to make an investigation of how authoritative conceptual framework about immigrants as a group is being constituted in the discourse regarding Swedish language for immigrants. I will also examine what connections there are to the overarching integration discourse. While doing this I try to establish the contrasting relationship between the ?Swedishness? and ?the Other?. My theoretical framework consists of discussions regarding groups and the relation to homogeneity or heterogeneity in various ways and how We tend to construct the discourse in relation to the Other.

An analysis of a specific application of anaerobic wastewater treatment at a pulp and board mill, Stora Enso Skoghall, was carried out. A literature study was done and effluent wastewater from CTMP pulp production was analyzed. The analysis consisted of a broad constituent analysis and an anaerobic treatment trial. Results from these test where used to calculate the treatment effectiveness and resulting energy potential at the mill.The literature study and constituent analysis showed that toxicity of the water to be treated, due to wood extractives and sulphur content, was of concern. Detoxification chemicals targeting these constituents where used in the anaerobic treatment trial.

ITT Water & Wastewater (före detta ITT Flygt) tittar på att eventuellt genomföra en förbättring av ytbehandlingen av deras pumpar för att eliminera de rostangrepp pumparna utsätts för idag. Examensarbetets uppgift är här att analysera och beskriva miljöeffekterna av de nya ytbehandlingsmetoderna som företaget undersöker.Målet med studien är att få fram ett underlag och en rekommendation om vilken ytbehandlingsmetod företaget bör välja ur miljösynpunkt.De olika metoder som studerats är:? Järnfosfatering + ED-lackering? Zinkmanganfosfatering + ED-lackering? Oxsilan + ED-lackeringDessa metoder har jämförts med nollalternativet, vilket innebär att samma metod som tillämpas idag fortsätter att användas.Miljöeffekterna som studerats för de olika metoderna är:? utsläpp till luft och vatten? avfall? energiAv de tre nya metoderna samt nollalternativet är Oxsilan följt av ED-lackering det alternativ som ger minst påverkan på miljön. Metoden har inga utsläpp av flyktiga organiska ämnen till luft, inget farligt avfall bildas och det avfall som ändå bildas är litet. Metoden har även lägre energiåtgång än de andra studerade metoderna.2008:Nr 2 Teknik.

This bachelor thesis aims to investigate how social workers in Uppsala describe their procedure when investigating applications for housing assistance (i.e. boendestöd). Boendestöd is a specific type of services for people with disabilities, which aim to assist them in their lives. This welfare service is one of many regulated by the framework legislation that is the social services act (SoL 2001:453). Previous research indicates that civil servants who make decisions based on goal-oriented framework legislations like SoL, have a great freedom to act when they make judgments and decisions.

The purpose of this study is to highlight some aspects of the increased usage of tablets in preschool environments by answering the questions: what does the tablet become in the preschool environment, how much freedom does the children have over its usage.To answer these questions a series of observations were made at two different preschools. The observations were then complemented by interviews with teachers at the same preschools.This qualitative study focuses on some of the didactic questions regarding the tablets, based on a theoretical framework that is within the design-oriented perspective; which addresses the children's? autonomy, the institutional framework and affordance.Our conclusion is that the tablet?s introduction in the preschool has helped the teachers in numerous parts of their documentation, but we can also see that the children's opportunities to make choices regarding the tablet are more limited than with any other resource on the preschool. In our results we also see that when the children get access to the tablet they receive a learning experience, which among other things, strengthens their language skills and their social interaction with each other..

Transfer of undertaking or business is a complex fact. It requires many aspects to be takeninto consideration. For there to be a transfer of undertaking or business, it has to be a stableeconomic entity that after transfer has retained its identity. The provisions regarding transferof undertaking or business is found in the transfer of undertaking or business directive,6 b § LAS and 28 § MBL.An employee?s employment is automatically transferred to the transferee.

The aim of this Master´s thesis is to examine which type of regime the state Iran is. There has been much research on this issue and the discussion is not over yet. I have departed from three theoretical perspectives in order to understand which type of regime the Middle Eastern nation is: theocracy, democracy and hybrid regime. The theocratic regimetype is composed by David L. Websters archeological theory about governments ruled by God.
