Light has always fascinated humans but ever since the invention of the first light bulb, the use of artificial lighting has accelerated dramatically. Darkness has never been as rare as today and the overuse of lighting has created a new phenomenon called light pollution. Most living beings are biologically dependent on the recurrent twenty-four-hour rhythm of light and darkness, called the circadian cycle. Human beings are evolutionary developed after this circadian rhythm and the effects of constant artificial light is yet unknown. Scientists fear the consequences of constant lighting and what it means physically, mentally and philosophically for the human species.

This master thesis is made of two parts. The first part concerns the method and results ofdesigning a motion control system for a piece of research-equipment called BIRGIT.

This study focuses on teachers? and pupils? experiences of their use of one-to-one computers in civics education in Swedish upper secondary school. The experiences of teachers and pupils will also be put in relation to the content of the formal curriculum. The aim of this study is to investigate whether the access of one-to-one computers has changed teaching and learning within civics. The theoretical approaches used are both Tomas Kroksmark?s theory about traditional versus innovative learning and Ruben Puentedura?s SAMR-model.

I detta examensarbetet undersöks hur provningen av HVAC på lastbilar skall utföras iklimatvindtunneln CD7 som Scania färdigställer till år 2013. HVAC omfattar kupéuppvärmning,ventilation samt AC och har därmed en stor betydelse för klimatkomforten inne i lastbilshytten.Med klimatvindtunneln CD7 kommer olika tester att kunna utföras i en kontrollerad miljö medallt från ökenklimat till snöig vinter. De nya möjligheterna som kommer med klimatvindtunnelnCD7 är även anledningen till att en ny provmetodik behöver undersökas och tas fram.Studien föreslår fyra stycken provmetoder för HVAC samt en struktur för dokumentationen.Provmetoderna som har valts fokuserar på sol-, regn- och snösimuleringar. Dessa provmetoder ärbaserade efter vad som kan samt bör testas i CD7, vilket är en del av syftet med examensarbetet.Solsimuleringar har i empirin visat sig vara bland de mest förekommande proven när det gällertestning av HVAC och klimatkomfort.Provmetoderna syftar till att skapa en utgångspunkt för konstruktörer och testingenjörer vidutformningen av prover. Det gör testningen repetitiv samtidigt som tid sparas genom attdokumenterat underlag finns att tillgå.En av målsättningarna med examensarbetet har varit att studien ska användas förvidareutveckling av provmetoder för HVAC på Scania.

Att vårdas i respirator innebär att den verbala kommunikationsförmågan förloras, vilket kan medföra känslor av frustration och maktlöshet hos patienter. För att uppnå en vårdande relation är samtalet av stor betydelse, vilket försvåras om kommunikationsförmågan är nedsatt. Syftet är att beskriva intensivvårdssjuksköterskors upplevelser av kommunikation med lätt sederade, respiratorbehandlade patienter. En kvalitativ ansats har använts. Halvstrukturerade forskningsintervjuer utfördes med åtta intensivvårdssjuksköterskor från två sjukhus.

BackgroundIncubators are important facilities for economic growth in society. The main purpose of incubators is to accelerate knowledge intensive firms onto their market by both providing resources and an entrepreneurial environment.Problem Companies within incubators are encouraged to share knowledge and experience with each other with the goal to stimulate development and invention of new technology. This exchange involves interaction on an inter-personal and inter-organizational level. Incubators need to create an open and transparent environment in order to enable this exchange on both levels.Purpose The purpose of this study is to enhance the understanding of how knowledge and experience exchange occurs within the context of incubator systems. By understanding how incubators can capture knowledge and learn from the incubator process, this study can contribute by insights of how the incubator process can be further improved.Method This bachelor thesis is written from an abductive approach and is based on a qualitative case study of Ideon Innovation in Lund.

Swedish agriculture has gone through big changes in the latest 60 years. The farm sizes have increased, which has led to raised tractor and machinery sizes and therefore increasing problems with soil compaction. A method to reduce these problems is to implement controlled traffic farming, CTF. All field operations are then concentrated to specific tracks by using GPS guidance. The aim of this work was to study how the tillage regime, with or without CTF, affects the soil, with the main focus on macroporosity. In Säby close to Uppsala, and Alnarp close to Malmö, randomized block trials has been carried out, and the data has mainly been taken from these trials.

In Italy in 1528 the famous author Baldassare Castiglione published the book Il Cortegiano. In words Castiglione portraits the ideal courtiers and provides a lot of advice on how to achieve the ultimate courtier manner. For example he introduces and explains the words sprezzatura and grazia. His advice spread from Italy and influenced the courts around Europe. My purpose with this study has been two folded. Firstly, I have analysed Castigliones Il Cortegiano in order to examine his vision of virtues and ideals.

Inom intensivvården vårdas patienter med sviktande vitala funktioner där respiratorbehandling ofta kan vara en del av behandlingen. Invasiv respiratorbehandling leder till att patientens förmåga till verbal kommunikation upphör. Patienten befinner sig ofta i en utsatt situation där förlust av förmågan till verbal kommunikation kan leda till känslor av rädsla, oro och frustration. Patientens nedsatta kommunikationsförmåga ställer höga krav på vårdpersonalens förmåga att förmedla och tolka information.Syftet med studien är att beskriva vårdpersonalens upplevelser av att kommunicera med den vakna intuberade intensivvårdspatienten. Studien genomfördes som en kvalitativ intervjustudie med induktiv ansats.

The new cataloging code Resource Description and Access (RDA) provides a system of instructions for recording relationships between related resources by means of a controlled vocabulary of relationship designators. The purpose of this two years master?s thesis in Archive, Library and Museum studies is to examine the construction of this system, as well as its theoretical foundation. One theoretical point of departure is the necessity of operational definitions for consistent identification of bibliographic relationships. Another such point of departure is that the theoretical model on which RDA is based (the FRBR model) is not a complete description of the biblio­graphic universe, but merely a limited representation of a set of assumptions about that universe.The thesis first examines Barbara B.

The situation on the Swedish labour market is different in opportunities whether you are a native Swede or someone who has a foreign background. People with foreign backgrounds tend to have lower wages, higher rate of unemployment and often have temporary employment contracts. There is a conception that the Swedish culture is the standard and other foreign cultures are abnormal and different. The purpose of this study has been to investigate why there is discrimination on the labour market against ethnic minorities and how the Swedish history has contributed to the structural ethnic discrimination that we are struggling with. I have been using the right dogmatic method and a social science perspective as complement in order to answer the purpose.
