AbstractThis report intends through a case study to investigate if lightweight concrete isappropriate as main material in the outer wall of a seven storey residential building.A technical design is carried out in accordance with the definitions and requirementsfor passive houses, given by FEBY?s1 ?Demand specification for passive houses?.A literature review is also carried out for a comparison between regular bolt wall andlight weight concrete wall, with a focus on the safety of moisture.The lightweight concrete block used in the report is as a celblock produced by thecompany H+H Sweden AB.The methods used have resulted in compliance with requirements andrecommendations from authorities. Calculations of energy, noise and moisture riskassessment has been carried out.The work has resulted in the conclusion that the lightweight concrete itself is notable to isolate in the extent necessary to obtain chosen U-value of 0,1 W/m2 ° C,without getting to thick. Therefore additional insulation is needed. There are fewrelevant reference objects built with only light weight concrete.
OTEC-Ett energialternativ för enhållbar ö
Ocean Thermal Energy Conversion (OTEC) is a technology that utilizes the temperaturedifference in oceans between the warm surface water and the cold water at 1000 m depthto produce electricity. The purpose of this report is to investigate if OTEC with its synergiescould become a commercially feasible energy solution for a small island. A literature reviewis conducted to explore the different OTEC technologies and to what extent the threesynergies; fresh water, air conditioning and aquaculture, could be used. In order to calculatethe profitability of these synergies there is also a study conducted on the conventionalmethods and cost of fresh water production, aquaculture and air conditioning. A model is setup using a scenario of a small tropical Island with population of 100 000 people.
Spotpriset på El : Kan dess förändringar förklaras av funda-mentala faktorer?
Denna uppsats undersöker vilka faktorer som påverkar förändringar i elspotpriset på Nord Pool. Avsikten är att resultatet skall ligga till grund för en prisuppskattningsmodell för Lunds Energikoncernen AB. Faktorerna bestämdes genom en förstudie där viktig litteratur om elmarknaden studerades samt samtal med Lunds Energikoncernen AB. De faktorer som undersöks i denna uppsats är priset på utsläppsrätter, nettoexport till Tysk-land, temperatur, nederbörd, priset på kol och villaolja samt konjunkturutveckling i Sve-rige.Undersökningen av faktorerna bestod av en multipel regressionsanalys med undersökta faktorer som oberoende variabler och elspotpriset på Nord Pool som den beroende va-riabeln. Faktorerna blev indelade i två grupper dagsgruppen och månadsgruppen, grunden till uppdelningen är som namnen antyder att statistiken var observerad dygnsvis och må-nadsvis.
Svartrost, Puccinia graminis f. sp. avenae, epidemiologi och bekämpningsstrategier i Mälardalen
Stem rust, Puccinia graminis, has caused enormous yield losses throughout history which have had significant consequences for oat and wheat production. Today in Sweden stem rust is only reported from rye, oats and wild grasses. Stem rust infections in wheat have become unusual due to the general use of resistant wheat varieties and also due to the eradication of barberry, Berberis vulgaris, the alternate host for P. graminis. According to international sources, new races of P.
Lärare och informationssökning. En undersökning av lärares utsagor kring sin informationssökningskontext
The purpose of this thesis is to reach a deeper understanding of the context of teachers? information seeking. Research in the role of the library in a learning perspective is in demand. To reach our aim we investigate what teachers say about their experiences of the user training during their studies and what effect it had on their information seeking as teachers. We interviewed four teachers and analyzed the transcripts of their sayings about their experiences of their information seeking during their education and a teaching profession.
The effect of abolishing milk quotas : a study of comparative advantages amongst European member states
The European Union provide 27 % of total volume raw milk produced in the world. This number is steadily decreasing due to that the world milk production increase is more rapid than EU production growth. The growing middle-class change the demand for food, a higher standard of living increase the demand of milk products as well as other various animal products. Since 1984 the EU milk quota has limited the supply from EU, but the quota will expire April 1st 2015. The European Milk Board expect that the removal of quotas will make the farm gate price decline.
Lokalproducerad mat: en studie av dagligvarubutikers förhållningssätt till lokalproducerad mat
The purpose of this thesis is to give an understanding of how grocery stores relate to local foods. Through a case study representatives for two groceries in Norrbotten have been interviewed regarding why they supply local foods, how they try to influence customers to buy this, and how they decide upon the assortment of local foods. The result shows that groceries supply local foods in order to supply a wide range of products and to mediate social responsibility, in order to create customer loyalty. Concerning how the groceries try to influence customers to buy local foods the result cannot give any clear-cut view. Instead it shows that a grocery that actively works to influence customers to buy local foods markets them in specific ways, while the opposite applies to a grocery that does not actively work for this.

Visualiseringsverktyg för Sykedjor
This thesis has been done in order to ease the process of drawing schematics ofelectrical wiring. The need arose after demand from the government due to a seriesof incidents that took place during the revision of the nuclear power plant in year2009.The task of the project has been to create a computer program that can generate agraphical representation of the electrical components relations. The basis for theprogram has been an example of how the client wants the graphical representation tolook. During the course of the project weekly meetings have occured in which theclient has reviewed the work.The result of the project is a program written in Visual Basic Applications that can berun in Microsoft Excel. The program is capable of generating graphics for a majority ofthe cases.
LHC - Strävan efter att öka den totala kundupplevelsen
In today's society there are a lot of offers towards consumers, where they actively have to choose the most appealing offer. In order for an offer to be attractive it must add value in line with the customers demand. Also, it requires that the offer provides a sufficient level of attraction so that the customer selects the particular product/service over another. Furthermore, each offer must exceed the expectations of the visitors to an event, so they feel that the event is something "extraordinary". We have chosen to study how LHC (Linkoping Hockey Club) works with marketing in order to improve the overall customer experience.

Lagring av kyla i bergrum : Undersökning av ett nedlagt oljebergrum
This thesis considers the use of an oldrock cavern as thermal energy storage.With a large system of differentchillers a model was created to find anappropriate future system. There aremainly two trajectories to take. Eitheran installation of chillers needs to bemade or the rock cavern can be used tomeet the future demand of districtcooling in Solna, Sweden. Additionallythis thesis investigates the possibleuse of different techniques to utilizethe phase change energy of water.Simulation shows that it?s possible toutilize the phase-change energy of afluid; however it?s not economicallyfeasible due to the thermodynamiceffects on the Carnot cycle.
