This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.

This thesis has examined the Tekla Structures modeling software and answered the question of whether it could act as a suitable modeling program for the design department at Bjerking AB in Uppsala. The method used in this work is a case study of a previous project with existing basis to work form. The demarcation of the study was to examine only the usability of the foundations of in situ concrete. The work examined three main areas within the design process. The first was to model the concrete elements then to model the reinforcing and ultimately production of the drawings. Because Autodesk Revit was the existing modeling program in the Department conducted the evaluation as a comparison between the two programs.

Energy issues are constantly increasing attention in today's society. People's impact on Earth isentered in more contexts. Many discussions are about how the entire social structure needs to bestreamlined in order to achieve sustainability. The residential and service sector accounts for 39 % oftoday's total energy consumption in Sweden and the increasing electricity prices have made buyersmore interested in energy issues.There are many buildings in need of refurbishment today, including all the apartments that werebuilt in the 1970s to reduce the housing shortage at the time. 650 000 apartments of one millionapartments were built during the so-called the one million program and is currently in need ofrefurbishment.

Syfte: Att undersöka om man avseende på ett debatt- och ett granskande program verkligen kan påstå att vi idag har en sådan representativ offentlighet som Habermas talar om (se Val av Teori). Det vill säga, att se hur den samhälleliga eliten presenterar sig själv och sin makt offentligt idag, i ett debatt- och ett granskande program. Frågeställning: Hur kan man konkret se att politiker och företagsledare med hjälp av en språklig och visuell retorik presenterar sig själva och sin makt i ett debattprogram och ett granskande program idag? Och vilka likheter/olikheter kan man då urskilja i den politiska självpresentationen mellan dessa program?Val av Teori: Jürgen Habermas teori om återkomsten av den representativa offentligheten som handlar om att den moderna samhällseliten har återutvecklat en modern form av representation, som går ut på att presentera och representera sin makt inför folket och inte för folket.Val av Empiri: Debattprogrammet ?Argument? på SVT 1 och SVT 24. Det granskande programmet ?Uppdrag granskning? på SVT 1, SVT 24 och SVT Opinion.Val av Metod: Den retoriska analysen, med ett semiotiskt förhållningssätt som vetenskapsteoretisk utgångspunkt.

The aim of this study is to compare attitudes to change among innovation and economics students and teachers at one of the universities in Sweden.Data about students? and teachers? attitudes to change was gathered using a survey.Keeping in mind that knowledge can lower ones resistance this study is based on a hypothesis that individuals from the innovations program have a lower resistance to change. The study is also based on earlier research in regards to comparisons between students and teachers.The results of the study show that teachers have less resistance to change than students. Individuals in the innovation program are however less resistant to change than individuals in the economics program.One can discuss whether or not results of the study show that the hypothesis is correct.The difference between individuals in the economics- and the innovation program are statistically significant and has moderate effects in reality. The differences between teachers and students are statistically significant but only have a small effect.It is however a starting-point for future studies that will possibly explore the subject more profoundly..

Uppsatsen beskriver varför lärare använder datorn i undervisningen och vilka hinder som finns för användandet. Den beskriver också vilka syften lärare har när de använder pedagogiska program och varför de inte använder pedagogiska program. Studien har genomförts i två delar. Dels en kvantitativ undersökning med enkäter riktade till lärare i Linköpings kommun, och dels en kvalitativ undersökning med intervjuer av lärare. Av undersökningens resultat framgår att datorn används mest till ordbehandling följt av Internetanvändning och pedagogiska program.

In 2006, Stora Enso Skog implemented an education program in water management for harvester operators, timber purchasers, cut block planners and supervisors. The focus of the program was creating stream crossings with minimal harm to the stream and the surrounding riparian area. This main purpose of this study was to determine the difference in work procedures before and after participating in the program. The methodology consisted of field studies and interviews with harvester operators and their supervisors. The field study looked at how the streams had been crossed concerning the number of crossings, visible damage to the stream and/or the riparian area made by the machines. Biological parameters such as the width and dept of the stream and amount of large woody debris in the stream were also measured. The field result from 30 harvesting sites showed no significant difference between sites that had been harvested before or after the education program. But the harvester operators and their supervisors experienced an increased concern for watersheds after the educational program.

The purpose of this Bachelors thesis is to investigate teachers' work and attitude to life in relation to the curriculum. Furthermore, how teachers look at students' emotional/social development in their general development. The thesis also reviews the criticism from The Swedish School of Authority on various programs primarily SET (social and emotional training)Three qualitative interviews and four observations at three different schools with teachers have been conducted. Using theories of social constructivism, deliberative conversation and social and emotional skills, the intention is to interpret the gathered material.The results show that the teachers see knowledge of life in school as important in the foundation of students´ emotional/social development. One teacher follows the SET program and two teachers? took inspiration from various other programs and ideas.

A study around some fourteen and fifteen year old boys, who are interested in reading. It is about their reading and library habits, what has created their interest and where they acquire access to literature. A certain amount deals with the habits of the boys? school-friends in this subject. The result compares with earlier made reports.

The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.

Att upprätthålla en effektiv konkurrens är något som EG-rätten syftar till. Genom artikel 82 i EG-fördraget förhindras dominerande företag att via ensidiga förfaranden utestänga konkurrenter eller begränsa konkurrensen. Det finns flera sätt, för ett dominerande företag, att påverka konkurrensen negativt och därmed göra sig skyldigt till missbruk enligt artikel 82. Ett förfarande som under vissa omständigheter kan anses som missbruk är att leveransvägra för att stoppa eller begränsa parallellimporten. I denna uppsats diskuteras och analyseras det om under vilka förutsättningar en leveransvägran kan anses som ett missbruk av en dominerande ställning.

Fresh water has become more and more of a scarce commodity. Water scarcity isn't first and foremost a cause of drought and wasting, but a cause of inequality and mismanagement. This is not only a problem for developing countries, and there can also be variations within countries. The municipality of Gotland has a development program called Vision Gotland 2025, with goals for growth and sustainable development. The aim of this study is to examine whether the use and management of water resources on Gotland and Vision Gotland 2025 is conformed to the Water Framework Directive and the Ecosystem Approach in terms of sustainability.

På uppdrag av Sweco Systems i Umeå har detta examensarbete utförts under våren 2013. Syftet var att undersöka huruvida något av de energiberäknings-program som används på företaget kan anses vara lämpligt vid energikartläggningar av befintliga fastigheter.Inledningsvis utfördes en energikartläggning av fastigheten Odin 12 i Umeå, som i huvudsak utgörs av gallerian MVG. Med resultaten från denna energikartläggning som grund beräknades därefter fastighetens energianvändning i två olika program ? VIP-Energy och IDA Indoor Climate and Energy.Resultaten från den inledande kartläggningen visar att fastigheten har ett lågt behov av fjärrvärme, vilket förklaras av fastighetens höga elförbrukning. Den stora användningen av el genererar stora mängder internvärme som, förutom att sänka fjärrvärmebehovet, även medför att fastigheten under hela året har ett kylbehov.Utvärderingen av de två beräkningsprogrammen visar att VIP-Energy är ett lämpligt program att använda vid energikartläggningar.

Syftet med denna rapport är att utreda vad matematik- respektive karaktärsämneslärare på yrkesprogrammen på gymnasiet anser att det finns för för- respektive nackdelar med en ämnesintegrering mellan deras ämnen. Med hjälp av en enkät har de två grupperna fått delge sina för- och nackdelar samt i vilken utsträckning de tillämpar en sådan ämnesintegrering. Enkäten användes också som underlag för en intervju som låg till grund för en beskrivning av hur ett ämnesintegrerat arbete kan gå till. Majoriteten av lärarna var positiva till att ämnesintegrera och ansåg att de tillämpade en sådan undervisning men endast ett fåtal samarbetade med sina kollegor över ämnesgränserna..
