Ljusföroreningar i stadsmiljö : Hur kan ljusföroreningar förebyggas vid nybyggnation?

Light pollution in urban areas - How to prevent light pollution at construction Jakob Sjöling Light pollution is a relatively new but rapidly growing form of pollution. Society's increasing demand for light coupled with the pace at which lighting technology evolves is accelerating that growth. The purpose of this study was to analyse how the construction industry plan and design outdoor lighting when erecting new buildings, specifically with regards to the issue of light pollution. It also investigated how local authorities work with these issues during urban planning. In both cases special interest was placed in ways to improve the planning and use of outdoor lighting in order to minimize light pollution.

Sveriges säkerhetspolitik under 2000-talet : En analys ur ett liberalt och ett realistiskt perspektiv

The purpose of this study was to examine and explain Sweden?s defence and security policy during the twenty-first century. The method that was used in this research was a case study. The material that was used were government documents focusing on this area of policy, and numerous books concerning the theoretical perspectives on international relations and defence security policy. The study is of an explaining art and the analysis explains Sweden?s security and defence policy during the twenty-first century. The analysis explains this by testing it against a liberal and a realist view on international relations. The conclusion of the study is that Sweden?s defence and security policy has been liberal during this time period ? and still is.

Regressionsmodellering av dynamiska råemissioner från statiska mätningar

By using steady-state measurements for predicting emissions under a dynamic drive cycle wouldsave a lot of time and money for the exhaust aftertreatment specialists at Volvo cars. The idea forthis thesis has been to investigate if statistical regression models can be used with good accuracy.Questions included are for example if common operating variables such as engine speed, air-fuelratio etc. is sufficient to predict engine-out emissions over the engine operating range with goodaccuracy. Focus was set on the modelling of warm engine, but also the more complex engineheat-up phase was investigated since it is a great contributor to total emissions. While NOxcouldnot be measured because of malfunctioning measurement equipment, only HC, CO andtemperature at inlet of first catalytic converter has been modelled.

Sverigedemokraterna: Från högerextremister till radikala högerpopulister : ? En idealtypsanalys av partiets politiska program

The Sweden Democrats (Sverigedemokraterna) has for a long time been the subject of study by political scientists. In the meantime they have been categorized as National Socialists, Fascists, right-wing extremists and more recently radical right populists. But it has not been categorized according to the theories that I expect. The purpose of this essay is to study how well Sweden Democrats policies match with ideas that are typical for radical right populist parties. The main research question is:- Are Sweden Democrats showing details which are typical for radical right populist parties?To be able to answer those questions, I have used an ideal type analysis and developed an analysis instrument according the theoretical approach and the methods in Bergström & Boréus book.

Manuell arytmitolkning och defibrillering prehospitalt för att minska avbrott i bröstkompressioner

Abstract Background Todays guidelines for advanced CPR emphasize chest compressions with good quality and early defibrillation. Prehospital CPR performed by ambulance crew, an automated external defibrillator (AED) is used. The AED analyzes the heart rhythm and the performer is following the advice to chock the heart or not, given by the AED. During on-going CPR there are sequences when no chest compression is performed known as hands-off time. Hands-off time includes the time for the AED to analyze the heart rhythm and the time when advice is given to the crew.

Beslutsmodell för inköp och lagerhållning av motorer i ett produktionssystem : En fallstudie på Sandvik

AbstractIt is important to choose which spare parts to keep in stock. With the right spareparts in stock the costs for inventory and production loss will decrease. Cavalieri et al. (2008) highlights that the balance between inventory cost and production loss is underestimated.  It affects the company and must be considered before decision on purchase.The problem with spare engines is that they are all more or less critical for the production. That can be a reason for why no previous research targeting engines and classification of with engine should be kept in stock has been found.

Arrende i ett föränderligt jordbruk

In 2006 the government assigned the Council of Cultural Affairs the task of making an update, consisting of 50 literary titles, to be added to the existing list called Alla tiders klassiker ? en klassikerserie för skolan (All-time classics suited for school).      The idea of ??a literary canon can be considered to be a tool for transferring socially, historically and culturally constructed norms and values ??from one generation to the next in order to create and maintain a common frame of reference. The common frame of reference affect the individual's thoughts and actions as well as their sexual desires and their own perception of self as a sexual being.

Nurses who often came in contact with people with mental illness had less negative attitudes and prejudices against mental illness. Aim: The aim was to examine the experiences from nurses in somatic care, caring for patients who also have a psychiatric diagnosis.

ITS under byggtid - utvärdering med dynameq : Fallstudie: Intunnling av E4/E20 Tomteboda - Haga södra

Essingeleden in Stockholm is the most heavily congested road segment in Scandinavia and it is ofgreat importance for as well traffic within the city as for transit traffic. The capacity of Essingeledenand Norra Länken is not enough to accommodate all traffic. At times it is not moving at all, whichresults in long queues and an augmented risk of accidents. Consequently measures for increasing thecapacity on E4/E20, which will reduce congestion and the risk of accidents, are implemented byTrafikverket. In fall 2012 one lane of three at Pampas will be closed and so will the exit fromEssingeleden to Norra Stationsgatan, called Parkeringsbron.

Implementering av höghastighetsgränssnitt i 0,15 µm halvledarprocess

This study investigated the possibility of implementing three standards, Transistion Minimized Differential Signaling (TMDS) and two versions of Stub Series Terminated Logic (SSTL), for inter-chip communication in a specific manufacturing process. The two SSTL standards were implemented in one transceiver system while TMDS was implemented in a separate system. The evaluation was done with Spice simulations on schematic level with some parasitic capacitance and resistance. The idea was to investigate the possibility of implementing these standards and get an idea of eventual shortcomings. In order to create models as a basis for evaluation, simulation environments with models for circuit board and packages were created and transmitters and receivers were designed.
