Social hållbarhet och förtätning : en kritisk studie i förtätningens sociala paradoxer
Densification is one of the urban visions for sustainable development - a vision that has become a part of the solution to the unsustainable sake dilemma. With the dense city land will be saved, energy consumption reduced and social cohesion improved. The dense city is considered to be ecologically, economically and socially sustainable. Applying an urban design concept has thus proven to be problematic. Density has been found to be a complex concept
which is far more complicated than measuring how much built surface that needs to be covered.
It is also not disputed what different degrees of densification mean and whether densification in itself is sustainable.
Inventering och bedömning av förorenade områden inom division Energi, Tekniska Verken i Linköping
This thesis was commissioned by Tekniska verken, Energy Division with the overall aim to investigate the concept of environmental debt and what it means for a business. Furthermore, a sustainable risk and responsibility investigation shall be carried out on the concerned areas. Finally, the priority areas shall be highlighted and proposed actions presented. The Swedish Environmental debt concept was presented in 1992 by Arne Jarnelöv. Environmental debt is defined as restoration costs for environmental damage. In the early days the concept did not take into account who was responsible, but the environmental debts was regarded as a humanity debt to future generations.
Utveckling av hygienfunktioner i diskmaskiner : Desinfektion med ånga
This report is the result of a thesis work in Integrated Product Development, regarding hygienic features in dishwashers and especially disinfection by the use of steam.The thesis is performed at Electrolux Primary Development Dishcare in Stockholm and in collaboration with the Department of Machine Design at the Royal Institute of Technology.The targets of the thesis are to prove the advantages of a technology suitable to implement as a hygienic feature inside a dishwasher and to realize a functional prototype of a differentiated hygienic feature that does not exist on the market today.The process followed to perform the thesis is the process defined for Electrolux Primary Development.The technology chosen for development is disinfection by heating the water on the surface of the dishware, by the use of steam.A number of tests on how steam behaves when injected into the dishwasher tub have been performed, providing the results that have been taken in consideration when designing the prototype.The prototype consists of a pipe system provided with nozzles to eject the steam into the upper parts of the dishwasher. Tests of the final prototype show that thermal disinfection of water in a dedicated area of the tub can be reached within 9 minutes. The operation requires 0,17 liters of water and consumes 0.2kWh..
Användarrelaterad energieffektivisering : En studie på länssjukhuset i Sundsvall
Energy efficiency is important both to reduce costs and to reduce greenhouse gas in the atmosphere. In Sweden 40 percent of the energy consumption is related to the buildings sector. Hospitals are complex buildings with different activities in the same building, which requires flexible technical systems for ventilation, heating and lightning. A quarter of the total energy consumption in Swedish hospitals is related to user activities in the hospitals. Therefore it is not only important to work with operational optimization but also to change user activities, to reduce energy consumption.The objective of this thesis was to examine the user-related energy efficiency work at two care units, at the central hospital in Sundsvall within Västernorrlands County.
WHAT HAS THE POWER TO EMPOWER YOU? Förutsättningar för empowerment: en kvantitativ studie av tjänstemäns upplevelser över empowermentfrämjande villkor
Introduction/Background: Economic evaluations help decision-makers to make informed decisions regarding resource allocation. Information generated from CEA can support evaluations of a new intervention with current praxis. The evaluations also provide information as to whether an intervention is cost-effective, both in economic terms and in health gains. Objective: The aim of this thesis is to investigate the use of economic evaluations in public health, with a focus on CEA. Use of economic evaluations is regarded as both a method for evaluation and as support for informed decisions.
Testplattform för nätverks-RTK i syfte att ge en rikstäckande GPS-tjänst med centimeternoggrannhet
Today?s wind power plants are only compensated for their reactive power consumption at no-load. As the wind power plants grow bigger the amount of reactive power they need also increases. This is no longer a problem that can be ignored, especially as the net owners are beginning to charge the reactive power they transport.In this thesis a couple of different methods of compensation and their prices will be discussed and evaluated. Problems, such as self-excitation, that can occur if one fully compensates the wind power plant will also be brought to surface.
Hur utvecklar enmansföretagare sin kompetens utifrån den uppfattade lärmiljön?
The purpose of this study is to gain understanding of how self employed entrepreneurs (hereafter referred to as ?entrepreneurs?) develop their competence based on their perceived learning space. The main question is: How do these entrepreneurs develop their competence based on their perceived learning space? Other questions relevant for the study are: How important is the social environment for these entrepreneurs and how do they interact with their social environment in order to develop their competence. The study has a qualitative approach.
Infectious bronchitis in Brazil : a minor field study in Bastos municipality, Sao Paulo
Infectious Bronchitis (IB) is a highly contagious viral respiratory and productiondepressant disease distributed world wide. The disease is caused by the InfectiousBronchitis Virus (IBV), a positive RNA strand Avian Coronavirus within thegenus Gammacoronavirus. Due to a combination of high mutation rate and atendency of recombination a constant emergence of new genotypes and serotypesis seen. In Brazil, a country with an extensive poultry production and majorproblems with disease control, the diversity of circulating strains are wide andoutbreaks of clinical disease despite intensive use of vaccines are common. Theaim of this study was to investigate the presence of IBV and to identify genotypesof isolated IBVs in a limited number of layer flocks in Bastos, São Paulo, as partof the screening for circulating genotypes in the country.

Förändringar och Förvillelser : Skriftspråkets modernisering mellan år 1895 och 1938 i en roman av Hjalmar Söderberg
This essay ? Discourse and Dissonance ? deals with Mary Shelley?s gothic novel Frankenstein; or, the Modern Prometheus (1818). The focal point is the construction of ?Them and Us?, as defined by scholars such as Stuart Hall, viewed in terms of the following categories: race, gender and family, class, and sexuality. Rather than applying an outside perspective, e.g.
"Trained to Empire, trained to rule the waves" : En jämförande analys mellan John le Carrés Tinker Tailor Soldier Spy och Tomas Alfredsons filmadaption
With the collapse of the Soviet Union and the 9/11 attacks, the landscape of the freedom of religion has changed. The issues now facing freedom of religion varies greatly from the issues that the drafters of the universal declaration of human rights faced after World War II.In the light of the new issues that States face in the intersection of religion and societal interest, scholars have criticized the European Court of Human Rights to give too much leeway to the States in determining how the human rights should be implemented, by using the doctrine of margin of appreciation. Critics of the margin of appreciation claim that it is based on culture relativism and that the doctrine undermines the universality of the human rights. In order to decide if the margin of appreciation has indeed led to a relativization of the human rights I compared it to the jurisprudence of the UN Human Rights Committee and its use of the Syracusa principles. My conclusion is that the jurisprudence of the European Court of Human Rights cannot be considered to be based on culture relativism.
Manliga pedagoger i förskolan : en kvalitativ undersökning om förväntningar på män och deras roll i förskolan
Media brings attention to the concept of preschools being in large need of more male teachers. In order to implement an increase of male teachers, various methods have been employed, most of which are based on the concepts of gender and equality. In question however, are the views of present teachers on the need for male teachers, and their expectations of those men! Or in other terms: What particular type of men are requested? And how does this correspond with the gender patterns induced by male teachers in their daily practical work? The purpose of this survey is to analyze expectations of male teachers and their role in the preschool context, through a gender perspective. I want to shed light on this purpose based on two questions: What ?kind? of men are requested by the present teachers? and Which gender patterns will the men induce to their daily work chores, and to their interaction with the children? The survey was conducted by means of interviews, polls, and observations, and the results were obtained from two preschools of which one in particular has extended focus on gender issues.
Avbördningskapacitet för Traryd kraftverk: en modellstudie vid dimensionerande flöde
Sydkraft Vattenkraft AB owns and operates the Traryd hydropower plant, located in the river Lagan in the southern part of Sweden. The gravity dam is classed according to RIDAS guidelines (Hydropower Industry Dam Safety Guidelines) as a class 1B dam. This means that the dam must discharge a class 1-flow which has a return period of 10 000 years. The inflow into the dam has been calculated in an earlier report to 495 m3/s, with a waterline at an elevation of 126, 3 meters above sea level. The gravity dam has a discharge system with two rectangular weirs, which results in a smaller discharge than the necessary 495 m3/s.
The Male Gaze som retorisktverktyg : En utredande litteraturstudie över hur the Male Gaze kan användas inom retorikvetenskapen
The thought behind this bachelor essay regarding gender and rhetorical feminist criticism developed years ago out of the fact that I read just a little too many dirty chick lit-pockets as a teen. Those chick lit-pockets were my first introduction to sex, to gender roles, to how men and women react and are supposed to react to each other and, in some sense, even to feminism. Those chick lit-pockets, later turning into hardcore Harlequin-books, became my benchmark when I started to contemplate the fact that this is a man?s world, produced and reproduced by a male gaze which influences everything from sex, porn, advertising, gender roles, jobs and payment to dirty pockets for teenage girls.The essays aims to show how the male gaze-phenomenon could be to use for the rhetoric discipline: first combined with other rhetorical theories as a way to analyze and understand gender and objectification. The main question asked; How to put the male gaze on a rhetorical leash? This bachelor essay consists of a qualitative literature study focusing on four articles and one book in which five different male gaze-perspective appears.
