Background:Investments in different forms have always been popular to every human being. For the most common investments, such as stocks and bonds, there are loads of information to gather for the investor. Historical data like risk, return, dividends and fundamental data like annual reports are often very easy to find, regarding these kinds of investments. The background of this thesis is the lack of market information in residential real estate investments. A problem with this investment is that there is lack of information regarding risk adjusted return for real estates, which this thesis intends to present.Objective:The objective with this thesis is to study which alternative, directly-owned residential estates or stocks, who generates the highest risk adjusted return.

Abstract: This study is focused on blogging from the perspective of the individual. Weinvestigate why one uses the weblog format, functions on the blog that are seen to work asdriving forces, attitudes towards self-disclosure and anonymity on the weblog and how therelation between an online- and offline-identity is interpreted by the bloggers themselves, forexample to what extent it is possible to get to know the blogger by reading the weblog.Finally, we investigate the weblog-readers meaning to the blogger, as well as their possibleimpact on both his or her personal blog-content and the everyday-life.The empirical material consists of half-structured interviews via MSN Messengerwith nine informants, being bloggers found on the Swedish website bloggportalen.se. Thetheoretical framework behind the interview guide focuses on the identity concept, containingidentity theories in psychological and sociological perspectives, symbolic interactionismconcerning the concept of roles, as well as Bauman?s liquid theory on postmodern societytendencies. This material is further included in related previous research articles, derived fromboth international and Swedish databases.

Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.

When cylinders for motor saws are manufactured there are high demands on the cylinders strength and wearing qualities. Aluminum is a material with low density and is used by Husqvarna AB for their motor saw cylinders. The aluminum is strengthening with nickel that is attached to the cylinders through electrolysis. When aluminum is in contact with oxygen a film of oxide is formed. To eliminate the oxide and to prevent formation of new oxide zinc is used.

Bakgrund Idag diskuteras det mycket kring vilken roll sockerkonsumtionen kan spela gällande de ökande hälsoproblemen i samhället. På senare tid har det flytande sockret lyfts fram som en av de stora bovarna i dramat och forskning visar på att läsk bestående oberoende av vanligt socker eller artificiellt socker, kan påverka hälsan negativt. Syfte Syftet med undersökningen var att granska ungdomars läskkonsumtion samt att ta reda på deras motiv till varför de föredrar att dricka vanlig läsk respektive lightläsk. Det är även av intresse att undersöka eventuella könsskillnader. Metod Undersökningen har gjorts med hjälp av en enkätundersökning med intention att beskriva ungdomars läskkonsumtion. Valet av undersökningsmetod syftade till att ge bredd åt undersökningen.

This master thesis has been a pilot study preceding a forthcoming project of a larger scale with the long term objective to separate the direct effect of added nitrogen on soil processes from indirect effects via trees. The aim of this study has been to investigate the allocation of nitrogen following direct injection of liquid solutions into the xylem of 40 year old Norway spruce. The field site is located at Flakaliden (64°07?N, 19°27?E), approximately 60 km northwest of Umeå, Sweden. A total of 18 trees were selected for treatment, equally divided between three treatments, potassium nitrate, glutamine and water (control).

Scandinavian Biogas is involved in the planning of a combined ethanol and biogas factory in Karlskoga, Sweden. Besides biogas and ethanol large amounts of digester residues will be produced, about 450 000 liquid tonnes residue (~7,3 % Dry Substance( DS)). The objective of this thesis was to investigate possible uses of the residue from the biogas production process ScandgasEthanol developed by Scandinavian Biogas, and to derive a methodological approach how to evaluate and compare handling systems. Three systems where proposed and compared in this thesis; spreading of the untreated residue as fertilizer (system 1), dewatering to a higher DS content to reduce transportation before spreading as fertilizer (system 2) and production of a solid fuel by dewatering and drying the residue (system 3). The general conditions for the proposed systems were investigated in terms of practical viability, economical aspects, environmental impact and energy inputs/outputs.

Important issues for the local authorities are what to do with the sludge produced insewagetreatment plants. The tax for landfill leads to higher costs with 250 SEK/ton. On the 31December 2004 it will be forbidden to landfill sludge.In Sweden the yearly production of sludge is 240 000 tons, counted as DS. The phosphorouscontent is 3 % in sludge. The total yearly production of sludge gives 6000 tons of phosphorous.

Pulp- and papermills expend vast amounts of water in order to produce pulp, paper and cardboard. Hence, they alsocreate vast amounts of waste water which has to be cleaned before it can be released into the receiving body of water. Insuch a wastewater treatment plant, tremendous amounts of energy are expended by the aeration in the biologicalcleaning process. This aeration is necessary to supply the microorganisms that shall decompose organic material withoxygen, which they need for their metabolism. The transfer of oxygen from the gas phase to the liquid phase isprimarily inhibited by surface-active substances in the waste water like resin acids or fatty acids.

Latent heat storage is a way to store thermal energy when a phase change material undergoes a phase change. The advantage of latent heat storage is the capability to store more energy per mass unit than other heat storage methods. The most commonly used phase change in latent heat storage is the transition between solid and liquid. Phase change materials can be divided into organics, inorganics and eutectics.In the Nordic electricity market the price of electricity is set every hour by Nordpool spot, which leads to price fluctuations because of changes in demand. The main goal of this report is to create a latent heat storage system in a single-family home and investigate the possibility to save money by charging the latent heat storage system when the price of electricity is low, and discharge when the price is high.The thermodynamic model consisted of a ?tube-in-tube? heat exchanger with phase change material in the outer tube and water as the heat transfer fluid in the inner tube.

AbstractDegree thesis Solid content in Lime Mud By Andre Flodin Process operator program ? Umeå University 17/6 ? 2014 Pages: 21A thesis was made on Billerudkorsnäs production unit in Karlsborg where lime kiln in the causticising department of chemical recovery plant does not meet the required production. Causticising department is the final step in the chemical recycling unit. There, the filtered green liquor is mixed with lime to recover the cooking chemicals used in the pulp factory. The cooking liquid is called white liquor.

The Swedish Welfare Act § 4 says that "Animals must be kept and cared for in a good environment for animals and in such a way that promotes their health and allow them to behave naturally." Pigs in the wild spend 80% of their waking hours walking around and rooting for food, eating and exploring their environment with its snout. Fattening pigs in commercial farms spend 80% lying doing nothing. A lactating sow is lying down most of her day, and only 10-20% of the body surface is in contact with the floor, so the pressure is high on these spots. Piglets lie down and paddle with their legs, with high liquid content in the tissues, several times an hour, to stimulate and massage the sow's udder. In the existing system, these individuals are held more often on floors that are anything but inviting to sleep on.

Ingen vätska kan ersätta vatten och utan vatten kan inget liv existera. Markens fysikaliska egenskaper och kemiska förhållanden styr spridningen av de föroreningsämnen som före¬kommer i mark och i vatten.Katrineholms kommun vill i framtiden kunna utnyttja vattenmagasinen i Forssjö. Ett antal observationsrör har placerats i Forssjö, vilket är beläget cirka 8 km sydost om Katrineholm. I dagsläget används inte GIS i kommunen och detta gjorde att jag blev intresserad av vilka möjligheter som GIS skulle kunna tillföra med utgångspunkt i den brunnsdatabas med vatten¬kvalitetsmätningar som finns i kommunen.Detta examensarbete består av två delar. Den första delen granskar risken för föroreningar från den del av väg 52 mellan Katrineholm och Nyköping som passerar Katrineholmsåsen sydost om Katrineholm.

Agricultural soils constitute the base in human food production and soil content of organic matter and plant nutrients together with soil microbial activity are all important parameters for high crop yield of good quality. These parameters are dependant on proper fertilization.Anaerobic digestion of organic wastes for biogas production generates a liquid residue called biogas residue (BR). It contains organic material and plant nutrients which makes ita potential fertilizer for arable cropping. However, it also contains heavy metals and toxic organic compounds and it is therefore in need of evaluation before usage.Microbial tests were performed aiming to evaluate the agronomic traits of four different BR and to find a viable procedure for evaluating slurry fertilizers. Two experiments where soil respiration and soil potential denitrification activity (PDA) was measured at fertilizer addition were performed.

It is possible to affect the feed costs in different ways. By steeping or fermentation the digestibility of the feed is improved for the animals with a natural process in the wet feeding system Steeping means that the feed is soaked some hours before feeding. This process activatesenzymes and improves the digestibility of for example phosphorus in the feed and make it more accessible to the animal. Wet feeding can be fermented or not. Fermentationmeans that the feed has been soaked for a certain length of time so that a biological process is started.
