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.

CSRD och det offentliga : En analys av svenska kommuners anammande av CSRD

The European Union's Corporate Sustainability Reporting Directive (CSRD) aims toenhance and standardize sustainability reporting to support the green transition. While the public sector is expected to lead in sustainability, the application of CSRD within Swedish municipalities is fragmented. Many municipally owned companies fall below reporting thresholds individually, creating a transparency gap despite the municipal group often exceeding these thresholds collectively. This discrepancy raises moral and strategic questions regarding public accountability and the effective utilization of the framework. This thesis investigates the rationale for the proactive adoption of CSRD principles bySwedish municipalities, irrespective of formal legal requirements.

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.

Estetisk Effektivitet i Digitala Spel - Konsten att skapa starka upplevelser

?Jag tyckte det var la?skigt sa? jag blockerade honom? : Teknikens betydelse fo?r tilla?mpning av motstrategier vid bemo?tande av kra?nkningar pa? na?tet

Instagram is one of the most common used social media platforms among teenagers today. It is not only one of the most common used social media platforms, but as well one of the most common places where cyber bullying takes action. By using focus groups, netnographic studies and a questionnary we investigate the meaning of technology regarding how the bullying on Instagram takes shape and the strategies used by teenagers to handle cyber bullying.Our research shows five different ways that cyber bullying takes shape and ten different strategies implemented to handle those. The findings are compared with previous research. The ten different strategies are then discussed from aspects that are found to have a big influence on how those are implemented: gender, knowledge, experience and awareness, presence of parents and other relatives, personal experience, trust in the technical solutions and the weaknesses of those. .

Visuellt kaos

Den här uppsatsen handlar om hur serietidningens narrativa likheter och olikheter med litteratur samt film och hur dessa kan användas för skapandet av ett ickelinjärt narrativ. Vi ville se var styrkan ligger i serietidningar för att försöka berätta en berättelse på ett nytt sätt som vi inte är vana vid att se. För att undersöka detta forskade vi kring vad ickelinjärt berättande är och vad som skiljer olika berättande medium från varandra. Vi applicerade sedan denna forskning i skapandet av en serietidning där vi testa de tekniker och metoder vi lärt oss om tidigare. Resultatet bygger på erfarenheterna som vi fått från skapandet av serietidningen och hur de olika narrativa likheterna samt olikheterna kunde appliceras på en serietidning.

"Helst ska den ju komma inifrån." : Om motivation och att lära ut engelska i högstadiet.

This qualitative study aims to investigate some secondary school teacers' attitudes to and experiences of motivation in their second language classrooms. Through qualitative interviews with five teachers some different perspectives on motivation and its function in second language acquisition have come to light. First, motivation is seen as something important and some teachers tend to distinguish between intrinsic and extrinsic motivation. Those who do so tend to value intrinsic motivation more highly. Secondly, teachers believe they can affect students' levels of motivation.

IKT som verktyg för lärande i historia : en studie av gymnasielärares syn på IKT i historieundervisningen

This essay examines the possibilities for the use of ICT for learning in the subject of history. By interviewing history teachers in upper secondary school about their experiences and thoughts regarding the subjects of learning, history and ICT, as well as the relations there between, based on Mishra and Koehlers TPACK model, I come to the conclusion that ICT may enhance learning in history. I also conclude that ICT may create new learning environments in history, where knowledge may or may not grow.The more unique ways of using ICT in history, compared to other school subjects, appears to be the possibility of using a variety of new sources, for example digitized primary sources from archives, that perhaps will motivate students, and make it possible to work from a con- structivistic point of view in history.Other unique possibilities are to satisfy the need of concretizing and visualizing the history being taught, by using a broad range of different media when presenting it. .

Framtidens meny för ett IT-system

The mission was to create a prototype of a menu system for the companySystem Andersson AB. The instructions were that it has to be as interesting andmodern now as in 20 years. We had to look at technology from the cutting edgeof development to make our prototype survive in the future. WindowsPresentation Foundation (WPF) was the technique we focused on. There areonly a few applications that take advantage of WPF today, but it is predictedthat WPF will be the next generation method for developing applications to theWindows platform.To make our menu visually appealing, easy to use and at the same timefunctional, we followed the clear path and guidelines that are available ininteraction design.

Utvecklingen av teknikundervisningen i år 1-6 på Dansäterskolan : ett illustrerande exempel

I samband med Lgr 80:s införande blev teknik ett obligatoriskt ämne i grundskolan. När Lpo 94 kom fick ämnet en egen kursplan och uppnående mål för år 5 och år 9. Det ställde krav på att man måste arbeta med teknik även i de lägre åren för att nå målen i år 5. Rapporter som är skrivna efter Lpo 94:s införande visar på dåligt resultat för teknikämnet. Dansäterskolan i Borensberg har i höst gjort en satsning på teknikämnet.
