Each year, the coffee machines at Ericsson in Kista produce around 100 tons of ground coffee waste.The companies Coor Service Management, Löfbergs Lila and Selecta are all responsible for differentstages in the logistical chain in delivering coffee and, together with Ericsson, they want to increasetheir environmental benefit. The plan is to produce biogas through anaerobic digestion instead ofincinerating the coffee waste in a heating plant. The results are to be presented as different businesscases in which different biogas plants are compared with the reference case (heating plant),comparing costs and environmental impacts.There are two major environmental benefits from producing biogas; reduced carbon dioxideemissions from when fossile fule is replaced by carbon neutral biogas, and reduced emissions fromreturning digestate from the bio reactor to farmland instead of using industrial fertelizer.In order to determine the biogas potential in coffee waste, a couple of properties had to bedetermined in a laboratory. Properties such as the dry substance content, heating value, moisturecontent and ash content. The results show that 100 tons coffee waste could produce around 16 500Nm3 biogas which would contain 163 MWh.The biogas reactor and upgrade plant both need energy gas to function and uses around 14 MWh ofthe produced gas.

In recent decades, demands has emerged that the companies shall take a greater social responsibility for the impact that they have on their environment and that this impact shall be reported, which is known as Sustainability Reporting. The Sustainability Report is based on a number of general principles that ensure the content and the quality of the Sustainability Report. One of these principles is the principle of completeness. In the research, this principle seems to have been interpreted in terms of number of reported aspects and indicators, which can be a limited view where only the existence of the aspects and indicators is observed. By including the degree of the reporting in terms of full, partial and no reporting as well as a comparison between the real and the alleged reporting, our intention is to extend the principle of completeness and to develop a tool that we also apply through an empirical survey in a particular area.

Det blir allt vanligare att elever får en egen bärbar dator eller lärplatta för att använda i skolan, även benämnt som ?en-till-en?. Digitaliseringen av skolan är numera så pass utbredd att det inte längre handlar om ifall datorer och digital teknik ska användas i undervisningen eller ej, utan snarare på vilket sätt de ska användas. I denna studie undersöks hur datorer används i undervisningen inom de samhällsvetenskapliga ämnena i en ?en-till-en?-miljö.

Tritordeum is the result of a cross between a wild barley (Hordeum chilense) and durum wheat (Triticum turgidum). Tritordeum have high viscosity and a nice yellow colour. The objective of this thesis was to evaluate Tritordeum lines HT 354, HT 361, HT 437, HT 2218 (JB3) and HT 1608 (JB1) for use as a new raw material within the food industry. Analyses made were on dietary fibre, fructan, ash, water content and colour. Compilation of data from analyses made for Agrasys an Agri-Food company in Barcelona having the commercial rights to Tritordeum, included Lutein and rheological properties.

This paper reports a study on the usability of e-commerce accessed through smartphones. There is much research in the usability of mobile interfaces and many sets of design patterns have been created but a few studies are available for specific domains, and in this report we focus on mobile e-commerce. In this study a framework is developed for how to design mobile e-commerce interfaces with a high degree of usability. Furthermore, the study also contributes a method to how other specific domain can develop a framework with general standards to work from when creating a web interface. By examining two sets of design principles and 14 design patterns, we evaluate which ones are critical in the design of a mobile e-commerce interface for achieving a high degree of usability.

Our premiss in this study is the escalating competition in the swedish newspaper market, which have become an issue regarding smaller editions for the newspapers, and some scientist have claimed that this has brought an sensational touch to their news. With this in mind, we have studied if a sensational touch is brought to the two biggest Swedish newspapersAftonbladet?s and Expressen?s first pages. Our purpose with the study is to look into the newspapers development regarding a more sensational newsworthiness on the front page over time. The use of quotes, images and news themes is indicators to measure the development.Trough a content analysis from three different years, 1972, 1992 and 2012 we have measured the data with the computer program SPSS.

Den tekniska utvecklingen av allt mer komplexa filsystem samt ökad lagringskapacitet på medier försvårar arbetet med att finna samt återskapa förlorade filer. Detta medför att de verktyg som används inom området ständigt måste utvecklas för att möta upp denna komplexitet.När filer ?raderas? av användaren hanterar filsystemet denna process på olika vis beroende på vilken typ av radering som utförts. Möjligheterna att återskapa dessa filer underlättas genom en grundläggande kunskap om filsystemets arkitektur samt de osynliga processer som sker.Inom den profession, till exempel digital forensik, där det insamlande materialet har krav att klara rättspraxis används olika metoder för att bevara materialets integritet. De kommersiella verktyg som används är utvecklade för att bemöta de krav som ställs inom rättsliga processer.

På Storängen i Söderköping bygger Bygg GG i Norrköping i samarbete med G Gunnarsons Fastighets AB ett hus innehållande 14 ägarlägenheter. Då försäljningen av lägenheterna startade innan huset var färdigt bestod den största delen av säljunderlaget av ritningar och skisser.Syftet med examensarbetet var att utföra en visualisering av det blivande husets yttre i form av en digital 3d-modell samt att visa hur några av de blivande lägenheterna skulle komma att se ut. Då många av lägenheterna i huset liknar varandra togs beslutet att visualisera tre av husets lägenheter.Rapporten beskriver hur arbetet med att ta fram visualiseringen genomförts. Den ger även en inblick i visualiseringsprocessen samt de programvaror som använts för projektet.Projektet kan delas in i två delar. En exteriör del och en interiör del.I den exteriöra delen byggdes en 3d-modell av huset i 3d-programmet Google SketchUp som är ett lättanvänt program för att skapa digitala skisser och 3d-modeller.

Background:An increasing number of patients with an oncology diagnose will be seen in the future. The oncology care is complex and in great need of nurses with a high level of competence. There is a lack of previous research in the specialist oncology nurses competence and therefore knowledge of their skills can reveal an understanding of their competence.Aim:The aim of the study was to describe the competence of the specialist oncology nurse.Method:Four oncology nurses and two directors of oncology care were interviewed. The interview text was analyzed using qualitative content analysis.Results:The result showed that the oncology nurses had developed six different competences within different areas. These competence areas were assertiveness, patient-centered care, ethical and moral-, pedagogical-, to lead and develop- and theoretical competence.

The purpose of this thesis was to study the origin of the local news in local newspapers. Do the news originate mostly from the police, the municipality, from press releases or from the reporters own ideas? We also wanted to find out what kind of content predominated in texts with its origin in press releases respectively the reporters own ideas. Of course we also wanted to find out if there were any similarities or differences between the two studied newspapers.We used a type of constructed week, but with non random selection instead of random. We chose one of each weekday the newspapers were published and studied the news covered in the papers that specific day.

I denna rapport undersöks möjligheten att automatiskt generera navigationsinformation och ett förslag presenteras på hur en algoritm för detta skulle kunna se ut..

Internet and social media have opened up new possibilities for companies and organisations tocommunicate their brand. It only takes a few seconds to communicate the message of a website to theuser. This indicates the importance of having the intended message of the website communicated clearlyin order to give the user a correct impression of the company or the organisation. When it comes to theconcept design of a website, it?s important that all different parts is presented uniformly.

Denna rapport är resultatet av ett examensarbete utförts på Linköpings Universitet och Karlstads Universitet. Syftet med examensarbetet var att undersöka och vidareutveckla en befintlig färgbaserad GCR metod.GCR står för ?Grey Component Replacement? och är nödvändigt för att få korrekt färg i tryck. Givet ett C-, M- och Y-värde returnerade den undersökta metoden C?-, M?-, Y?- och K?-värden som var tänkt att ge samma färgintryck som i föregående fall.

This study aims to examine the views on digitization of eight respondents, all working at different libraryinstitutions in Sweden, and how their views are reflected in their library's digitization strategies. The poll wasconducted on the basis of Ingrid Mason's theory of information standards, their structure and sociopoliticalnature. The informantion standards are divided into three aspects, curatorial, semantic and technical, and theyaffect selection of, intellectual and physical access to the digitized material, which in the end is what constitutes the digital cultural heritage.The background to the study is that the Swedish library institutions in the current situation lacks a nationalstandard or a common strategy for the digitization of cultural heritage, while it is still implemented digitizationprojects at many library institutions. The method used is qualitative, structured interviews with open-ended questions.The study shows that one of the main motives behind the libraries' digitization projects is to make librarymaterials available in a new way, creating greater opportunities for the users to take advantage of the material.The library users are the ones who mainly control what is digitized, although aspects of preservation ismentioned. Furthermore, it appears that the respondents believe that digitization offers improved capabilities tosearch and learn more about the collections, but the actual work of image capture, the addition of metadata,presentation to users and long-term preservation is very complex.Views on what it is to be digitized, how the material should be selected and provided with metadata and howit should be presented to users is what creates the standards that libraries use when they digitize their materials,and digitization of library materials creates new conditions for new users to access and use library material.This is a two years master?s thesis in Archive, Library and Museum studies..

The last hundred years humans have drastically changed the amount of available nitrogen in nature. Today human activities release twice as much available nitrogen as all natural processes are doing together. We also have degraded nature´s possibilities to take care of nitrogen through the draining of wetlands and straightening of rivers. In order to regain the potential of nitrogen retention in the water systems there now requires a reshape of the landscape we live in. A planned expansion of the mining activities in Garpenberg, Dalarna, would double the content of nitrogen in the waters below the mine.
