The subject of this paper is the congestion tax in Stockholm, Sweden. The study has been conducted with the purpose to examine of how public attitudes towards congestion charging looks and the reason behind the attitude. And also to examine if there are any differences in attitudes between those living inside and outside the payment zones, between men and women and between car owners and those who do not own a car or have a driver's license. The study used a questionnaire sent out electronically to a group of friends of friends and of friends? family members.

The task to this thesis has been to create an application, Katana-databas 1.0, for analysing c-code. The generated output gets stored in a data structure which content in the end of the program run gets written in a textfile which gets used by Katana. It's a tool for reverse engineering, developed by Johan Kraft at Mälardalens institute.Katana-databas has got the following limitations. (1) It can only handle preprocessed files, meaning it doesn't contain any rows beginning with "#". (2) Only complete files can be handled.

Hammarby Sjöstad is a new district in Stockholm with high environmental standard. Stockholm Water Company evaluates a local wastewater treatment plant with cutting edge technology. The first step is an experimental treatment plant (Sjöstadsverket) with four parallel lines of treatment, each with a capacity to treat wastewater from 150 persons. Within the membrane technology subproject the possibility of using reverse osmosis (usually called RO) to regain nutrients is examined.Reverse osmosis separates the incoming water in a clean permeate and a concentrate that, as the name indicates, is a more concentrated version of the incoming water. Using this method in wastewater treatment, a solution high in nutrients can be obtained without the use of chemical precipitation agent and with no production of sludge.

This essay is a comparative research between pupils' experience of how the headmaster, teachers and other school staff interpret and apply the democratic education. The results are based on a survey carried out in senior high school, as well as interviews with the school staff. The democratic education charge has a long history of Swedish school system and is the basis for the maintenance of a democratic society. Both policy paper of state investigations and researchers in the field, regard to school as the primary and unique instance in order to promote and develop democratic skills in children and young people. However, it is shown that those who come out from school lack of knowledge and awareness of democracy and the will to speak their mind.

The last decade has created an increasing pressure on companies to decrease their impact on the environment and to increase their effectiveness of recycling the company?s resources, especially for the steel industry. Companies have also started to realize the economic aspects of an effective internal reverse logistics. In the past the value of an effective internal reverse logistic was something that companies tend to underestimate and there are few academic studies done in this area. The purpose of this essay has been to identify key factors to create an effective in plant storage, transport, sorting and handling of returned steel. From these factors a generalized model for creating an effective return steel flow will be developed.

The fishing port of Bläsinge is located on the east coast of Öland, Sweden?s second largest island. Today the port has a limited supply of freshwater. The economic association of the fishing port wants to expand their business, so that they will also include tourist services. To do this the harbor will need a more independant source of freshwater, with a higher quality than the present well.

Purpose: In order to curb the prevalence of undeclared work and to improve competi-tion within the building and construction business, reversed charge audit will from July 1, 2007 onwards be applied within the building sector. The new rules entail a consider-able amount of delimiting problems as regards both businesses and services.The aim of this essay is to study the rules as well as direct the light upon various consequen-tial delimiting problems. Furthermore, we will investigate what the effects are on the busi-nesses, as well as their view regarding this. Apart from this, we will also investigate who will benefit and who will be disfavourably affected, respectively, by the new lawMethod: The investigation has been conducted with a combination of qualitative and quantitative methods. Firstly, an opinion poll was carried out, directed towards Swedish construction companies, and this was then deepened using three interviews.Result & Conclusions: The essay demonstrates that the new rules have entailed more work to a varying degree for the companies.

I början av 2000-talet producerade Riksskatteverket en rapport vilken undersökte skattebortfallet inom byggbranschen. Rapporten gav bland annat ett förslag om att införa omvänd skattskyldighet för mervärdesskatt inom byggsektorn, byggmoms. Lagförslaget i prop. 2005/06:130 klubbades av Riksdagen och trädde i kraft den 1 juli år 2007. Under det första halvåret avgjorde SNI-koder vilka tjänster och företag som skulle omfattas av den omvända skattskyldigheten.

BackgroundThe opportunity for cochlear implantation has now extended beyond children who are only deaf or hard of hearing. Children who are deaf blind from birth or early in life are receiving implants, but very limited research has been done for this population, and this raises important issues. AimThe aim of this study was to estimate the prevalence of hearing and vision impairment or deaf blindness in children with Cochlear Implants in Sweden and to investigate the diagnoses issues among these groups of subjects. Material and MethodSubjects with an age between 1-18 years were ascertained through multiple sources and almost complete ascertainment was achieved.ResultsA total of 77 subjects with a referring diagnosis of combined hearing and vision disorder or deaf blindness were ascertained. Out of those, 30 subjects were excluded.

Most of the portable electronic devices use a battery as a primary power source. Nowadays, when the applications are becoming smaller and smaller and more power efficient, the designer needs to concentrate more on reducing power consumption, using secondary power sources and introducing power storage devices. Multiple power source availability and a power storage device on the board will make the applications much more useful and efficient in everyday use. This thesis proposes a power supply unit (PSU) for wireless sensor platforms which is capable of supplying a sensor node with energy from multiple sources, as well as status information from the PSU. Present power storage devices, like electric double-layer capacitors (EDLCs) and batteries, have become more and more common as their characteristics have developed.

The continuous process of urbanization results in demands on research and development for ecological and sustainable city development. Because of this, the current systems for wastewater treatment may have to be improved. In order to evaluate new technologies for municipal wastewater treatment, a development project has been initiated for the new district Hammarby Sjöstad in Stockholm. The project is lead by the company Stockholm Water. High environmental standards have been put up for the district, as it must be twice as good as an ordinary new district.

Reverse logistics is getting more and more attention both from companies and the public. It is an area with the possibility for companies to do good in the eyes of the public. This work focus on the return system of a one-way handling material called the loading ledge. The loading ledge is developed by IKEA as a substitute for the EUR-pallet in transports from suppliers with a long distance and even flow and in transports from suppliers with short distance and uneven flow. The loading ledge is made out of 100 % recyclable plastic.The purpose of this work is to find the most efficient set-up for recycling of loading ledges within IKEA on a European level from a transport and handling point of view considering aspects like cost, environment, time and, from an administrative point of view, user-friendliness.Who will the participants of the set-up be, where will they be located, which transports are needed and which income and costs does the set-up generate, are questions that will be answered.

The objective of this thesis is to make a training material for KSU, which shows how radiation affects the different electronic components in a radiological environment.All electronic systems in the presence of high ionizing radiation can experience difficulties and be destroyed.This influence may compromise the control system and thus the safety of a nuclear reactor plant.To achieve this objective requires a description of electronic components and sensors, to better understand its function.This thesis will also show the possible solutions available that the author found interesting.Organizations such as NASA, CERN and ESA have worked to develop electronic components immune to radiation. Those organizations have also developed a test protocol that guarantees to a certain extent the security of electronic components in a radiological environment.Since we know how the material reacts with the radiation, it could develop a material that can be resistant to radiation or like CMOS technology has proposed, to reduce the component to avoid the storage of charge in the oxide.Another solution can be the GRAPHENE. Its features will revolutionize the electronics and provide answer to the radiation problems, Graphene will replace Silicium and the electronic components will only have a few nanometers dimensions so the oxide area also reduces, and in this way avoid the known problem of storage of charge..
