Kvarteret Kajutan - Från lågenergi till plusenergi

Energy and environmental demands regarding buildings have become an increasinglydiscussed topic, both in Sweden and in Europe as a whole. The general trend indicatesthat greater efforts are being put into the energy efficiency of the built environment.There are already numerous examples of houses with a low energy demand, and thenumber of low energy buildings is constantly growing.At the time being, the maximum level for energy demands for housing in Stockholm is110 kWh/m2year, but as soon as next year the limit will be changed to 90. The Swedishagency Energimyndigheten is currently conducting a project to interpret the EU Directiveon the so-called Nearly zero energy buildings, and the preliminary results indicate thatthe level of requirements for purchased energy will end up with about 55 kWh / m2year,which is in line withtoday?s recommendationsfound in FEBY's Kravspecifikation förPassivhus.Starting with a low-energy house in Henriksdalshamnen in Stockholm, we have analyzedvarious energy-efficiency measures and their influence on power and energy needs. Thefinancial aspects associated with the measures have been studied using a model of lifecycle costs.The measures were initially studied individually to give an idea of how much impact theyeach had.

Multilateral och unilateral säkerhetspolitisk praktik och strategi för hantering av Syrienkonflikten

This security study attempts to explain the dynamics of international conflict management of an intrastate conflict, through a combination of three theoretical frameworks. The conflict in Syria is shown to be managed mainly through strategies using coercive diplomacy, and some main contributions within the research field relating to strategies of coercion are used for guidance, to important factors which could affect coercive international conflict management, as well as to additional theories which could enhance the study?s explanatory power through a combined theoretical framework. The two added theoretical frameworks are Power Balancing and a Multidimensional concept of Power. With the aid of analytical tools derived from this combined framework the conflict management is analysed within both a multilateral and unilateral setting, offering some explanation as to why international conflict management (practiced by UNSC multilaterally and USA unilaterally) has shown so little progress in regard to the conflict, as well as why one significant, though limited, result could be achieved regarding the destruction of the Syrian regime?s chemical weapons arsenal..

Konditionstester i rehabiliteringssammanhang : - En litteraturöversikt

During the past few years there has been an observed decrease in physical fitness within different patient groups. As a part of the rehabilitating physiotherapy treatment it is important to acknowledge the physical condition of the patient. Physical fitness testing might be difficult due to physical limitations within different patient groups. A broad range of exercise tests is therefore of importance in clinical practice. The aim of this overview was to describe exercise tests used in rehabilitation contexts, and to define areas of use and restrictions.

Vindkraftsacceptans i olika etableringsfaser. En jämförelse av acceptansnivån i tre områden inom Mariestads kommun

The purpose of this paper is to contribute to a deeper understanding about the acceptance of wind power. Our basic assumption is that local conditions are important and can explain how the acceptance of change at different stages of establishment. The main purpose is to see if there are differences in the acceptance of wind power in different stages, and examine the factors that influence acceptance. That includes how people in three different areas of study estimates that they value their environment and how it is affected by wind turbines. The project was conducted interdisciplinary geo-targeted and consists of three parts.

CarEye ? Sees & Saves:    Fordonskamera för skadedokumentering

In the middle of Australia there is a city called Alice Springs. The city has one of the highest amounts of daily sunshine hours and sun irradiation in the world. The Australian Government runs a project called Solar Cities, and Alice Springs is one of the participators. The main part of the goal with the Solar Cities project is to increase the amount of electricity generated by solar power and by doing that lower the impact on the environment. This thesis examines the possibilities for construction of a large scale solar power plant in Alice Springs. This is done to determine the potential of creating a more sustainable energy system in the city.

Making Money in a Dirty Business

Academic research concerning how to determine the power situation in a supply chain where an investment product supplier is involved did not exist. Therefore new models has been developed that analyses the power relations and maps out the power situation in a supply chain. In the future these models can be applied on similar cases by modifying the included parameters. The new models show that case company FAS should focus on the big producers of garbage bag which are Trioplast, Rullpack and Miljösäck. By strengthen the brand FAS can make more money in these relations.

Geotermisk fjärrvärme i Gunsta

Gunsta is situated about 10 km east of Uppsala. Today there are plans to establish 1000 new households in Gunsta before year 2030. The required energy for heating houses and water would be distributed via a district heating system, which also includes 200 existing residences. The annual required energy, according to this study, would be 16.2 GWh with a maximal peak effect of 6.9 MW. To meet this need, the study suggests a system with heat pumps to upgrade the 31?C water from a 1.8 kilometre deep borehole.

En snäll tantroman gör ingen skada en kritisk studie om skyltning och makt

The purpose of our thesis is to take a closer look at what lies behind the display of fiction in public libraries. Through interviewing ten librarians and analysing their statements, it examines the mechanisms behind the displaying of books. The analysis was conducted through the application of two different theories, one by Aant Elzinga and one by Douglas Raber. Elzingas theory concerns methods of working, while Rabers theory concerns the purpose of public libraries and attitudes towards power. The following conclusions were drawn from analysing the statements.

"Change doesn't come easy" - A comparative study of Corporate Social Responsibility in large-scale dam projects

The process of economic globalization has in recent decades increased the power of multinational corporations. In recognition of their powerful position, corporations have begun to adopt Corporate Social Responsibility as a way of managing their social impact. Their interaction with the surrounding society reaches a peak when involved in large-scale projects, such as the Three Gorges Dam in China and the Narmada Valley Development Project in India. This essay analyses the concept of Corporate Social Responsibility in a comparative study between the two cases. By using current research, it focuses on the role of civil society for making Corporate Social Responsibility effective in developing countries.

Vems är makten? : En analys av hur makten i barnlitteraturen förändrats på 35 år

Each year a significant number of children?s books, with a wide range of themes, are being published. The relation between children and adults is a common theme. In this study I have analyzed ten children?s books, five from the 1970?s and five from the 2010?s.

Implementering av en PSS i Trängslets kraftstation

The purpose of this master thesis is to implement and validate a Power System Stabilizer (PSS) to a generator at Trängslet hydropower station in Dalarna, Sweden. Problems with local rotor oscillations can occur at the hydropower station when power is transferred on a new power line (130 kV) from Northern to Southern part of Dalarna. To ensure good operation properties on this power line Fortum Generation AB and Fortum Distribution AB wants to activate a PSS on a generator.There have been investigations in which situations and what equipment that contributes to rotor oscillations. When this is known the PSS is tuned to damp these oscillations by choosing a good set of parameters. The most important parameters for good performance are to choose amount of gain and phase compensation.

Transientanalys för Forsmark block 2 och 3 : Studie av hur val av driftpunkt och pumpreglering påverkar torrkokningsgränsvärdet

The dry out criterion (MCPR) has been calculated for the most limiting H2-events for Forsmarks unit 2 and 3, at operating points that are normally not analyzed before each cycle. The operating points that normally are regarded as the ones with the lowest margin to dry out are the ones where the thermal power is the highest at agiven recirculation flow. This report shows that this is not the case for Forsmark 3. MCPR-values at partial power operating points are higher for the limiting case inside rather than on the boundary of the region of operation. It is therefore recommended that the method for determining the dry out criterion for Forsmark 3 is revised to account for this effect.

Läsinlärning och självförtroende : Hur kan barns självförtroende påverkas vid läsinlärning?

In what French philosopher Gilles Deleuze labelled Control Societies, mechanisms reminiscent of censorship ? that is, restriction of information that administrators of power wish to regulate the spreading of ? are present in the concept of copyright. This kind of censorship has theadvantage of not being scrutinized by public eyes in the way that the work of institutionalized censorship agencies such as the Swedish Statens Biografbyrå was. It is not unlikely that expanded possibilities for punishing anyone who spreads copyrighted material will result in larger and larger areas that may not be accessed, as the avoiding of conflict and repressive actions will emphasize the behaviour to take detours around information that is deemed taboo and therefore suspicious and dangerous.The ACTA trade agreement is one proposed tool for such extended possibilities for punishment. This essay does not however claim that copyright and censorship are the same ? but rather that the institutional execution of power that was previously a matter of state censorship has a lot of similarities with current and prognosticated application of copyright laws by corporations.While claiming to protect the individual, the disciplinary power executed actually aims to protect the one executing it; the purpose of the power structure is to replicate itself..

Dimensionerande vattenförbrukning och dess variationer

I Sverige användes det år 2010 ca 907 miljoner kubikmeter dricksvatten från kommunala uttag. Allt detta vatten måste kunna transporteras, vilket görs genom vattenledningar. För att dimensionera dessa krävs att man vet hur mycket vatten som skall distribueras och hur det varierar bl.a. beroende på när under dygnet, veckan och året som uttag sker.Vid dagens tillvägagångssätt för dimensionering av vattenledningar till nya områden använder man bland annat typexempel på förbrukningsvariationer under dygnet för ett liknande område. Dessutom används erfarenhetsbaserade värden på maxtim- och maxdygnsfaktorer.Dagens dimensioneringsätt har ej kunnat säkerställas på grund av otillräcklig och bristfälligt detaljerad data över förbrukningsmängd.
