The purpose of this degree-project was to investigate the possibilities for primary air preheating into the two smallest waste incineration boilers of Halmstad Energy and Environment. The investigation is a pre-study which has the primary goal to evaluate technical and financial offers from companies that manufacture primary air preheater, and investigate if it is technically and financially profitable to do a purchase on primary air preheaters in the future.In the pre-study it is proposed that it is most efficient to have individual primary air preheater, one for each incineration boiler and the primary air are also proposed to be preheated by hot water in the pre-study. Further in the pre-study it is proposed that the heat-exchanger should have plain tubes instead of finned tubes, to avoid getting dirty fast. The space in the boiler-room is limited, and therefore the major problem was to fit in the primary air preheaters into the boiler-room. By comparing the different offers from the companies, the result in the pre-study shows that the offer from the company C.A.

Bakgrund: Sällskapsdjur har ett flertal positiva hälsoeffekter på människor och det har lett till att viidag använder djur inom vården, främst hundar.Syfte: Syftet med denna litteraturstudie var att undersöka hundens användande inom vården, attbeskriva och förklara dess effekt på människor.Metod: Metoden var en litteraturstudie och elva vetenskapliga artiklar granskades. Dessaanalyserades och sammanställdes utifrån gemensamma teman.Resultat: Vårdhundar inom vården kan i de flesta fall reducera ångest och acceptansen av vårdhundär mycket god både bland patienter, anhöriga och personal. Minskning av blodtryck ochhjärtfrekvens råder det delade meningar om, då vissa studier visar en minskning av dessa och andragör det inte. Vårdhundar kan användes till att vara motivationshöjande för patienten.Slutsats: Vårdhundar har många positiva effekter på människor, men fler studier behövs för att seom dessa resultat inte bara gäller för de grupper som har undersökts i studien utan även äröverförbara till andra grupper..

Trycksår är en vårdrelaterad skada vars prevalens är utbredd på sjukhus i Sverige. Denna hudskada uppkommer när ett ihållande tryck orsakar att underliggande vävnad skadas. Riktlinjer finns utformade för hur preventionsarbetet med trycksår ska utföras, och syftar till att minska prevalensen av trycksår. Syftet med studien var att undersöka sjuksköterskors syn på trycksårsprevention relaterat till patienter som ligger inlagda på somatisk vårdavdelning. De undersökningsmetoder som användes var av både kvalitativ och kvantitativ ansats. Materialet samlades in via enkäter och det slutliga informantantalet uppgick till 29 informanter.

Intense competition and pressure from various market participants is prevalent in today?s modern and technologically developed society. It is important to keep a high standard of service and customer care to be able to keep your position on the market. The focus of the paper is to study how a store manager can influence their employees to perform better on the job, in terms of service to customers and increased sales. The aim is to analyze the different tools store managers use to motivate their employees with the goal of improving service to the customer and to increase sales.

It's an everyday experience shared by many that nature can be of help in relieving pain, reducing stress, support mental recovery etc. In the last three decades or so this experience has also found support in a large number of scientific investigations. Among other things the experience of nature has been shown to reduce stress and pain in patients and to boost concentration and reduce impulsive behavior in children. Most of this research however has mainly been concerned with the visual modality. In this thesis the aim has been to focus on the auditory modality in this context by trying to reveal some effects on people from the exposure of nature sounds played indoors in three different environments: a grammar school class room, a kindergarten play room and a post-surgery wake up room at an intensive care unit.

Många byggnader är idag fuktskadade. Fuktskador uppstår på så väl nya som gamla byggnader. Idag provtrycker man hus för att få ett värde på dess täthet, men många hus som klarar täthetskraven drabbas ändå av fuktskador. Detta beror på att otätheterna är lokala på en eller flera delar av klimatskalet bortsett från otätheter vid anslutningar.  En studie har gjorts på två väggtyper; en standardvägg och en passivhusvägg.

The purpose of this master thesis was to study the water system for mechanically cleaned water at Skärblacka mill, in order to find and evaluate possibilities of using energy more efficiently. The thesis also includes an evaluation of the software tool ?Pumpanalys?Skärblacka mill produces pulp and paper. The large amount of water required is cleaned mechanically through filters and called mechanically cleaned water (MR0). The MR0 water is pumped out to the factory by four crude water pumps.

Studiens övergripande syfte är att belysa och gestalta det sociala stöd respektive sociala tryck personer sjukskrivna för utmattningsdepression anser sig uppleva från omgivningen, vad gäller både att vara sjukskriven och att återgå till arbete. Undersökningen genomfördes med hjälp av kvalitativ metod, och sex personer som var sjukskrivna för utmattningsdepression intervjuades individuellt. Resultatet visar att de sjukskrivna upplever en komplex blandning av både press och stöd i processen att ta sig tillbaka till arbetslivet. Stödet, oftast i form av förståelse och undvikande av press, upplevs främst från personer i individens nära omgivning, medan pressen att återgå till arbete oftast relateras till personer och grupper på längre avstånd. Störst press att återgå till arbetet upplevdes från den "samhälleliga" normen "att göra rätt för sig", men även omgivningens okunskap och brist på förståelse upplevdes som en press. .

Lattelement AB in Ornskoldsvik is one of the leading companies in Sweden in composite elements in walls, floors and roofs in particular. The company supplies elements to buildings located with a wide geographical variation, which means that the products are subjected to very different climate with regard to snow, wind and humidity. This places high demands and requires the elements to withstand large variable loads.The elements are made of lightweight beams with flanges of structural timber and beam webs made of OSB. These are bound together by nogging pieces with the same kind of structure. On top of the beams a nailed and glued plywood is added to absorb compressive forces and on the underside of the element a sheet of steel is added for tensile absorption.These elements are then attached to the building framework in different ways depending on the particular element height, loads and the structual supporting material of the frame work.

Predatory pricing is one of the most frequently discussed topics in competition law and should be considered both from a legal and economic perspective. The concept of predatory pricing can bedescribed as a situation where a company is pricing at a level that, according to the assessment theories, is unreasonably low. The problems with this type of conduct arises when the low prices hinder competition. A company which uses predatory pricing will likely deter rivals entry to the market or drive the existing ones out of it. In the long run, the effects on competition will likely be higher prices which will hurt customers and consumers as well as competition.

The European Council agreed in 2008 on a climate and energy package to combat global warming. This package is valid for each EU member country and means that greenhouse gas emissions must fall by at least 20% and the EU's energy use to 20%, consisting of Renewable Energy in 2020. The Swedish Government has set stringent climate and energy with the intention to set an example for the rest of Europe. For example, renewable energy sources account for at least 50% of energy use and our climate emissions to fall by 40% by 2020. A combination of these goals and a steadily rising oil price has led to an increased demand for wood fuel in the form of such branches and tops.

Title: Pricing of IPO:s on the Swedish stock market Authors: Mikael Gustavsson Martin Kvist Henrik Wannberg Tutor: Anders Hederstierna Problem: There are certain sets of problems for underwriters when they are pricing potential stock-exchange companies. The problem partly consists of estimating the demand at an IPO and also to accurately value the business in comparison to the market. To set the price per share is problematic, since the company carrying out the public offering wants to optimise the amount of capital at the same time as they want the share to be subscribed in full. If the IPO would not be carried out, it could cause harm to the position of the underwriters. Purpose: To investigate whether underpricing exists associated with IPO:s on the Swedish market during the period 1995-1999.

Background: More than half of the elderly (65-84 years) in Sweden have problems with hearing. In some studiesit?s discussed if age related hearing loss or presbyacusis is a part of natural aging or if it depends on underlyingfactors.The purpose of this literature study was to analyse scientific papers which illustrate correlations between lessknown underlying factors and presbyacusis, defined from psychoacoustic and/or neurofysiological tests.Material and method; Literature study where scientific papers, relevant to the purpose of the study and thequestions at issue were found in the database PubMed.The result shows that cardiovascular disease, hormones, diet and drugs have an influence on presbyacusis. Thehealth condition of the individual and their lifestyle matters, likewise estrogen which according to the results of 2studies has a protective effect on hearing.Conclusion; The studies show that heart attack and high systolic blood pressure in women have a correlation topresbyacusis, but not in men, - the hormone estrogen, - some vitamins, antioxidants and diet have a protectiveeffect on hearing and studies show that smoking and alcohol have negative effects..

Recent turmoil surrounding nuclear power as an energy source, especially since the accidentat Fukushima, has largely contributed to the debate of whether or not nuclear power should beused as an energy source. This study has examined the economic feasibility of replacingForsmark?s 3rd nuclear reactor with a bio fueled power plant, and find out how this could bedone.The power generation that has to be replaced is equal to 1170 MWe. To replace this, 6 largescaleCFB-boilers, each providing over 200 MWe, were necessary. In addition to this, eachboiler required their respective turbine sets, comprising one high-pressure-, and one lowpressureturbine with intermediate reheating capacities.Based on this, a rankine-cycle was modeled using the software EES, to be able to calculatethe total heat required in the power plant.

In today's society, the availability of energy plays an integral part in our everyday lives. Unfortunately, the price of energy in Sweden has increased in recent decades. A large part of our energy consumption goes to heating modules for houses, where heating methods that depend on energy sources such as electricity, district heating, fuel oil, gas and biofuels are the most common ones. During the winter period, the increase in energy costs becomes significantly evident, especially for small property owners. This increase in energy cost is most noticeable for home owners with electric heating.This thesis is written at the Halmstad University, in cooperation with a company, which makes parts of this thesis confidential.
