Companies that invest in e-learning have different expectations regarding the outcome of the investment. According to literature and articles it is common that companies see reduction of costs as the primary benefit with e-learning. Therefore we ask ourselves the question if companies have attained the expected benefit of the investment in e-learning and to what extent cost reduction have been a determining factor in the investments? The purpose of the thesis is to examine if companies that invest in e-learning have attained the expected benefits. We also want to examine what the reason for investing in e-learning is and if cost reduction is the primary reason for investing. The study is founded on a qualitative method that is based on a case study in eight companies.

There is a new beverage container on the market, a bottle made out of pure aluminum as a replacement for the traditional container made out of glass. This new container has the potential to reduce both cost and pollution during transportation, the lighter and stronger construction has every advantage compared to the old one in glass. The new container has every possibility to make it on the market. Some of the biggest brands within the soft drink market already use these bottles in countries without any recycling demands like: Coca-Cola, Heineken and Pepsi. The only thing stopping these brands from the Swedish market is the lack of a functional return system, there is only one company that uses the bottle in Sweden today and they take care of their own used bottles.

This report examines the prerequisites for LEDs to replace other technologies indifferent applications. How does the different technologies for light generationwork and what are the advantages and disadvantages? The various technologieslimitations and characteristics provides the opportunities for the LEDs.This report describes a test-construction built to examine what practical arrangementscan be built with modern light emitting diodes, in order to showsome of the possibilities. The construction consists of three different applications,a high power lamp based on cold white LEDs, one based on warm whiteLEDs for the evaluation of the light characteristics and a RGB-LED based lampable to mix any colors quickly and seamlessly.

Root rot is a big hurter and a huge economic problem for the Swedish and European forestry. The severest hurter is Heterobasidion annosum (Fr.) Bref and it occurs as two different species in Sweden. Commonly referred to as the P-type (Heterobasidion annosum s.s. (Fr.) Bref.) and the S-type (Heterobasidion parviporum Niemelä & Korhonen). Therefore a lot of research has been carried out in this topic to find a solution and reduce this problem, one alternative that have shown to be profitable is stump treatment in thinnings.

An increasing number of heat pump producers have developed heat pumps that can be connected to solar panels. In this thesis we have examined the possibilities of connecting solar panels to existing ground source- and geothermal heat pumps that has not been adapted to solar panels. During the work process, a prototype plant has been built to compare our theory with the practical results and with our designed sizing tool. The work has rendered in knowledge that will be used to build a sun module that can be easily connect to the existing heat pump system. The existing heat pump, our test plant, has been supplemented by an advanced storage tank used to allow different operating modes.

This thesis describes possibilities for Metso Paper to lower their costs of spray pipes for their pulp wash press TRPE, with maintained good functionality and quality.Information that can be used by competitors has been censored in this version of the essay.To find solutions, alternative suppliers have been contacted and asked to quote. There has also been a new spray pipe designed. The manufacturing costs of the new design have been calculated.The thesis also contains a concept generation of an alternative product to the spray pipes in installations where a high pressure washer is used.To be able to ask other manufacturers of spray pipes to quote, a demand specification based on the currently used spray pipe was made. This was then sent to two alternative suppliers.An investigation of earlier used spray pipes, and the currently used, shows that the nozzles are a big part of the total costs of the spray pipes. To attempt to reduce the nozzles high cost an concept generation was made to find the best solution for a new design.There was a request that it should be possible to change the internal brushes in the spray pipe without cutting and welding.

Abstract The aim of this study is to find out how teachers view the importance of reading in the teaching of foreign languages. In relation to this, we wish to gain understanding of what teachers want to achieve with reading, how they choose texts and what difficulties they encounter in getting their students to read. Six teachers from three different upper secondary schools in southern Sweden were interviewed for the study. We also examined the text-materials that they were using for their instruction. The findings show that students read mostly adapted texts from textbooks and, to a limited extent, authentic materials.

Pontarius AB har tillsammans med Göteborgs Hamn AB identifierat behovet av en utvecklad holistisk modell för bedömning av investeringar i terminalytor. För detta har en första ansats gjorts med den interna livscykelkostnadsanalysmodellen Total Cost of Ownership and Operations (TCOO). Livscykelkostnadsanalys (LCCA) är ett verktyg för att handskas med ett projekts totala kostnader vid investeringsbeslut och bedömning av alternativ. Generella livscykelkostnads-modeller är svåra att ta fram, varför istället utförliga modeller vanligen skapas för specifika områden. För vägbeläggningar, och tillviss del flygplatsbeläggningar, finns utförliga sådana metoder, men för beläggningar i containerterminaler saknas det.För att fortsätta utveckling mot en bättre bedömningsmodell för terminalytor syftade studien till att identifiera kostnadsparametrar som sett ur ett livscykelperspektiv påverkar kostnaderna för containerhamnterminalytor.

In recent years, existing solutions for cooling personal computer CPUs have been supplemented by a new product category, factory sealed water cooling loops. These systems, consisting of a water block with an integrated pump, a fan and a radiator, perform well compared to the air cooling solutions but are less effective than larger, custom-built water cooling systems.This project aims to explore the most important aspects of a factory sealed system and to identify possible cost-effective enhancements of the performance.The most significant differences between the different groups of water cooling loops are the block design and the pumping power. The performance of both categories is also largely dependent on the fan power, but increasing fan power has a large negative impact on the noise level.Both radiator size and fan model choice appear, in tests, to be relatively unimportant, presuming that the noise level is kept constant. The position and direction of the fan, however, has significant impact on both the temperature and the sound level.Water blocks can be designed in several different ways, both regarding the heatsink design and the flow direction. In simulation, flow with the inlet centered above the heatsink result in considerably lower pressure drop and slightly higher temperatures than flow through the block, for heatsinks with fin arrays.Creating a competitive product in this product segment certainly seems possible, as there are performance-increasing changes to be made that seemingly has little impact on the production cost.

This study?s purpose was to examine which main forms of teaching methods that occurs in the Swedish nine-year compulsory school and how often learning through social collaboration take place. The study contained literature and interviews with eight teachers. Our research-questions were: What is the teacher?s opinion about different teaching methods, their opinion about learning and teaching and if there were any difference between the teachers teaching younger or older students regarding teaching methods? Our conclusions of this study were that ?lecture-methods? is the most common among teachers.

This thesis studies the concept of balance in the management control systems (MCS) of a small Swedish company within the IT-sector. The aim is to evaluate the importance of balance and dynamics in MCS and investigate which factors affect them. The frameworks used are Simons (1994) four levers of control, and the five-factor model for balance and dynamics by Mundy (2010). The small IT company - the object of the case study - has grown extensively in the last years and needs to develop more formal MCS without losing efficiency and creativity in their fast-moving industry. The case study reveals that balancing MCS is important also in smaller companies with less formal MCS.

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.

Theft without break-ins has increased significantly in the last year of swimming, sports and leisure facilities in Karlskrona, more precisely 60%. Vandalism in the shape of graffiti is another common crime. The solutions are divided into social and situational crime prevention. Social crime prevention engage in actions that are based on social causes of crime rather than the opposite situational crime prevention, which instead assumes that discourage with the help of technical solutions and has as primary objective to hinder accessibility for example theft friendly goods. The main purpose of this work is to come up with solutions to prevent these crimes, while also being cost-effective and realistic to implement. The work is important in that it creates safety awareness and promotes a healthy safety culture. Moreover, the future goal is to lower these statistics. The goal of the work is in addition to developing our knowledge of crime subject, was also to provide help and solutions for our clients.

The aim of the present study was to evaluate if pulsed inhaled nitric oxide (PiNO) could be used as a treatment for hypoxemia during general anaesthesia in colic horses. Previous studies have shown a positive response in horses receiving PiNO in comparison to controls, but these studies have only included healthy individuals. A total of 30 horses were included in this present study, they all underwent abdominal surgery because of acute colic that could not be medically treated. Fifteen of the horses received PiNO and 15 horses served as a control group. Arterial oxygenation was improved in all horses receiving PiNO.
