Undersökning av luftkvaliteten vid småskalig biobränsleförbränning i två kommuner med modellsystemet VEDAIR

An Internet application, VEDAIR, for estimation of air quality in regions with small-scale combustion of bio fuel has been developed by Swedish Meteorological and Hydrological Institute with financing from Swedish Energy Agency and Swedish Environmental Protection Agency. The model contains user interface and a coupled model concept where concentrations of atmospheric pollutions are calculated for regional, urban and local contributions. In this report the model is described and a first study of air quality considering PM10 (particles with a diameter less than 10 µm) in two Swedish municipalities, Vänersborg and Gnosjö, is introduced.According to the result, there are areas with poor air quality even in smaller Swedish municipalities, mostly due to high emission from buildings with older wood heating furnace without hydraulic accumulator.In Vänersborg three areas were analysed in VEDAIR for the year 2003: Vargön, Mariedal and the downtown district. In the whole municipality the upper evaluation threshold for PM10, which is defined as 14 µg/m3 for annual average, was exceeded due to background contribution of particles. In all areas, however, the concentrations of PM10 were less than the environmental quality norms.

Variationer av klor, svavel och aska i havrekärna : odlingsfaktorernas inverkan på havrens bränsleegenskaper

The increasing oil prices during the last years have made it profitable to use cereal grains as a fuel. When compared with wood, cereals contain higher amounts of Cl, S and ash. The Cl and S content makes the gases from cereal combustion more corrosive than gases from wood combustion. The goal of this master thesis was to find out the variation of Cl, S and ash content for oat grain grown under different conditions. Oats was chosen because in Sweden it's considered as the cereal with the best fuel qualities.

Varumärkesutvidgning ? En viktig komponent i företagens affärsutveckling

Syfte: Syftet med studien är att analysera och beskriva hur ett företag kan arbeta med varumärkesutvidgning samt identifiera framgångsfaktorer, motgångar och bakomliggande orsaker som kan förekomma vid en varumärkesutvidgning.Metod: Vår studie utgår främst från den kvalitativa metoden. Inledningsvis presenteras ett ramverk för lämplig teori för att vidare kompletteras med intervjuer. Den empiriska delen består av kvalitativa intervjuer med företagen King Salming AB, Salming Sport, Peak Performance, Björn Borg och L`Homme Rouge. Slutsats: Vi har funnit stöd i, att teorin som avser varumärkesutvidgning kan användas i verkligheten. Samtliga bolag följer en varumärkesstrategi där kärnvärden och territorium utgör basen för en varumärkesutvidgning. I de fall där varumärkesutvidgningen inte fungerat som tänkt är det också avståndet till kärnvärdet och territoriet, som är ett av det återkommande problemet.

Värdepremium på den svenska marknaden - En residualvinstvärdering med säkerhetsmarginal

This paper attempts to investigate the correlation of 12 month abnormal returns and the fundamental value of stocks in theSwedish stock market between the year 2000-2011. Also, the paper tries to apply and evaluate the concept of the margin ofsafety. In estimating the fundamental value we use the residual income valuation model and three different estimationapproaches of the beta coefficient in order to correct for financial and operational biases. We find that our different portfoliosearn abnormal returns. However, this could be explained by the size effect and P/B effect.

Sveriges bostadsmarknad - Befinner vi oss i en prisbubbla?

This bachelor thesis aims to analyse the Swedish mortgage market and investigate whether it is in a current price bubble or not. Comparisons have been made with Denmark, a country with a market similar to Sweden?s, and where the mortgage market faced a price bubble that crashed in 2008. The housing market in Stockholm has been analysed as a separate market, as it differs from Sweden as a whole in prices and underlying factors to increased prices. The conclusion of this thesis is that not Sweden, nor Stockholm, is currently in a price bubble at the mortgage market.

Testosteron och matematik;Fingerlängd (2D:4D) : en indikator för matematisk förmåga?

En individs prenatala testosteronhalter kan mätas genom att ta fram ett relationstal mellan längden på pek- och ringfinger: ett 2D:4D digit ratio index. Studier har visat att det finns ett samband mellan högre testosteronhalter och god matematisk förmåga. I föreliggande studie deltog 40 svenska gymnasieungdomar. Två hypoteser undersöktes: det finns ett samband mellan 2D:4D och matematikresultat samt det finns ett samband mellan kön, 2D:4D och matematikresultat. Datainsamlingen bestod av fingermätningar och provresultat i matematik.

"Fettpärlan har vi så det räcker till alla!" : En jämförande studie av hur fyra lärare på de studieförberedande och yrkesförberedande programmen tänker och arbetar kring och med litteraturundervisning

On 1 January 2005, IFRS (International Financial Reporting Standards)was mandatory for all listed companies within the European Union. The introduction is to create a transparent and consistent reporting. Mainly to provide companies, investors and financiers the same access to world capital markets. Since the introduction of IFRS, the goodwill value is determined by annual impairment tests. If an impairment of goodwill is a fact the goodwill decreases in value.

Ruminants´production within agroforestry systems in rural Rwanda : production benefits and problems

Intercropping involving trees is called agroforestry and makes it possible to get higher production for every area unit. The trees can function as food, fodder, fuel, medicine; prevent mark erosion and much more. Agroforestry can also be combined with animal husbandry. The aim of this study was to document the animal production systems used by rural small-scale farmers maintaining ruminants and using agroforestry in the northern province of Rwanda. The farmers using agroforestry is expected to have higher milk yield than average due to homegrown protein. The method used during the study was semi-structural interviews with booth open and closed questions. In order to get in contact with farmers that matched the criteria; small-scaled rural farmers with ruminants and using agroforestry, the ?Vi Agroforestry Programme? (Vi-Life) in Kigali were contacted and the staff worked as supervisors, translators and contact with the farmers throughout the study. During the study nine individual farmers, two cooperatives breeding sheep and one group interview were conducted.

Effektmätning i pump

The interest for power and energy measurement has greatly raised with todays increasing electricity prices and enviromental awareness. In the search for energy efficient solutions, the measurements are more complex due to increasing of non linear components. Harmonics and non sinusoidal voltages put high demands on sampling and filtering. Meanwhile, the price must be controlled so the customer still will find it interesting to invest in smaller plants. ITT W&WW asks for a robust, heat resistant power meter with compact dimensions to allow mounting inside the casing of a pump.

En ödmjukt auktoritär rådgivning : Ethos och etik hos föräldrarådgivaren Petra Krantz Lindgren

Wermland was affected by the Spanish flu like the Swedish national average, about a half percentage of Wermlands population would lose their lives to the flu during the autumn 1918. The flu has for many fallen into oblivion. This oblivion is so wide spread that it´s possible to talk about a "collective forgetfulness". The society have selected to remember 1918 for "when the guns went quiet on the western front" and not for the millions who died from the treacherous Spanish flu. The world had already suffered enough from the four years of war that had been fought, thus the victims of the flu would be honored but would soon fade in to oblivion.  When you investigate deeper you get the picture that the national average don´t do Wermland and its cities or rural areas any justice when a large variations seems to occur within regional areas.

Tidsstudie - grovfoderhantering :

Since feeding fodder crops to dairy cows is a heavy and time-consuming but often disregarded line of work, this study wishes to view the different possibilities that are currently available to decrease the time to feed and apply this knowledge on an existing farm. For this purpose, four farms have been studied due to what feeding systems that are currently used and how long time the feeding required. The occurring systems are either mobile, i.e. a feed mixer operated by a tractor witch feeds the cattle via a drivable fodder table, or a stationery mixer, i.e. an electrically powered mixer which fills an automatic feeder.

ATT VARA ÖPPEN FÖR OLIKHETER I TIDER AV FÖRÄNDRING : Barnmorskors och BVC-sjuksköterskors erfarenheter av föräldrars behov av tidigt föräldrastöd

Society has an obligation to offer parents support of various types, an example of such a support is ?parent support?. The purpose of this study has been to describe midwives and child health care nurses conceptions of the need for early parent support. The definition of early parent support in this study is the first two weeks after delivery. Since the 1970:ies the Swedish delivery and ?BB? care has changed in that the time in hospital care after delivery has been reduced from in average six days, till an average of two days.

Removal efficiency of perfluoroalkyl substances (PFASs) in drinking water : evaluation of granular activated carbon (GAC) and anion exchange (AE) using column tests, and the effect of dissolved organic carbon

Poly- and perfluoroalkyl substances (PFASs) are a group of environmental contaminants that have gained increasing attention due to their potential to bioaccumulate, environmental persistence and potential toxicity. PFASs have been found in surface water, sediment, air, soil, sludge and ice caps globally, as well as in wildlife and humans. Furthermore, PFASs have also been detected in drinking water, leading to raised concerns for human health, since drinking water is one of the most significant sources of PFASs for the general population. Conventional water treatment techniques have shown to be ineffective removing PFASs, highlighting the importance for further research to develop efficient removal techniques. The aim of this study was to investigate the removal efficiency of PFASs in water using two treatment techniques; granular activated carbon (GAC), type Filtrasorb 400®, and anion exchange (AE), type Purolite A-600. Additionally, the effect of dissolved organic carbon (DOC) on removal efficiency was studied.
