Wastewater treatment is increasingly controlled by the Swedish environmental quality objectives, adopted by the Swedish parliament. There is a need for a sewage system that can fulfill stringent requirements concerning the environment, recycling and resource use and hygiene. Additional environmental aspects in recent years are the impact of climate change, new knowledge about the effects of pharmaceuticals in water, the need for improved wastewater treatment and increased recycling of nutrients to agriculture. This report has, from a future scenario of the year 2050, analyzed seven different systems for wastewater treatment and treatment of compostable biowaste from households in Eskilstuna. A future scenario was chosen based on that within a forty year period new challenges may arise which can result in higher demands on sewage treatment than those we see today. Another reason why the future scenario was established is that changes in wastewater treatment systems are slow to establish. The analysis is mainly focused on the economical aspects but environmental aspects such as emissions to receiving waters and potential recycling of plant nutrients has also been evaluated briefly.

This is a study in how astronomy has been taught and is being taught in Swedish schools from 1905 to this date with an emphasis on the latest 30 years. It concerns the regulations and methodical recommendations/curricula for Swedish junior high school/Swedish Comprehensive school for the years 1905, 1933, 1955, 1958, 1962, 1969, 1980 and 1994. The matter of integrating astronomy with other subjects and different methodical approaches is also considered. The problem with textbooks written only for one subject when the teacher tries to integrate subjects is emphasised.Physics textbook analysis shows that astronomy teaching has over the years developed, from being based on observations, to become more and more theoretical. It also shows that the amount of practical exercises has been fairly constant in physics textbooks during the seventies end eighties but now in the nineties varies a lot from textbook to textbook. The amount of liberty the textbook gives the pupil in finding knowledge and answers himself in the practical parts of astronomy was at its lowest during the seventies.

This work is about Cuban music and my relationship to it. My study contains two different parts. In the first one I try to give a short summary of Cuban music history. The second part is about possibilities and problems that can arise in the meeting with foreign cultures. I have focused on three themes: Music and respect, cultural encounters and travelling, and communication.

Vi lever i ett informations- och teknologisamhälle och i våra dagliga aktiviteter omges vi av vardagsteknik (VT) på olika sätt och i olika svårighetsgrad. Denna VT kan innefatta allt från brödrost till mer avancerade datasystem och tjänster. Tidigare studier visar att personer med kognitiv funktionsnedsättning kan uppleva svårigheter i användandet av VT i sina dagliga aktiviteter. Dock finns inga studier som visar relevans och svårigheter med VT för yngre vuxna utan kognitiv funktionsnedsättning. Därför vill vi med den här studien beskriva relevans och svårigheter i användandet av VT hos yngre vuxna utan kända kognitiva funktionsnedsättningar.

The use of information technology (IT) is exploding. Today, it is in our daily routines to use some kind of information technology. The increase of users increases the number of cyber crimes, ie, crimes that in some way involve IT. As the cyber crimes grow in numbers, the workload for technical investigator increases, these are called digital crime investigators. The thesis is about how police digital crime investigators work and what problems they may encounter during an investigation.

This report covers a description of the military support attainable to society and made available by the Swedish Armed Forces, in the event of a crisis. The main focal point is the needs of the rescue services..

The current planning philosophy is based on a political utopic modernism founded during the first part of the 20th century. The focus is, in planning a defined area, to maximize the internal efficiency and to create a competitivesociety. During the latter part of the former century globalization changed the context, thus creating the need for a new way of approaching physical planning. This paper shows that the historical and philosophicalmetaphor of flow can be applied to meet the demands in the global city. It also shows how the edge, as where interaction takes place, is an important part of the content that has to be defined.

Studiens syfte är att utveckla kunskap om lärares motivation till användning av digitalteknik i undervisningen. Ämnet belyses genom frågeställningarna; Vilken förståelse har lärare för den digitala teknikens roll i undervisningen? och Vilka aspekter påverkar lärarnas motivation till användning av digitalteknik i undervisningen? I studien deltar fem verksamma lärare som undervisar i årskurs 1-6. Utifrån semistrukturerade kvalitativa intervjuer beskrivs och kategoriseras aspekter som påverkar lärarnas motivation till att använda digitalteknik i undervisningen.   Studien visar att tvetydighet präglar lärarnas förståelse för den digitala tekniken. Lärarna uppvisar en förståelse för teknikens möjligheter och utnyttjar den för personlig utveckling och som informationsbank.Det framkommer dock inte lika frekvent att den digitala tekniken används i undervisningssituationen.   Det är flera aspekter som påverkar lärarnas drivkraft att använda digitalteknik i undervisningen.

The main environmental problem for aviation is the great amount of exhaust gases, mainly nitrogen oxides, carbon monoxide, carbon dioxide and hydrocarbons - mostly "greenhouse gases" leading to climate changes. I decided to sort out what is being done to decrease these problems and what regulations there are concerning air pollution by the means of searching the internet and using publications from aviation authorities for current figures. I chose to scrutinize authorities on political, authority and company level, resulting in summarizing the work of UN and EU respectively, ICAO (International Civil Aviation Organization), JAA (Joint Aviation Authorities) and LFV (Swedish Civil Aviation Authority), and finally SAS, representing the airline companies. Conclusion that I have drawn are thatthere are regulations for air pollution, written down in ICAO's Annex 16, that are to be followed. Secondly, LFV are environmentally controlling their nineteen airports and since economy is an important reason for not giving priority to environmental issues in aviation emission charge and noise charge are added to the landing fees.

Millions of preselected progeny have been born since the development of The Beltsville Sperm Sexing Technology 1986. The method is based on flow cytometry and sorting is done on the basis of DNA difference of the X- and Y-chromosomes. Preselection of progeny provides an opportunity to obtain genetic gain and increased production as well as increased animal welfare and decreased environmental impact. However, the method is associated with low fertility, high costs and uncertainty whether the sorting process contributes to DNA damage and thereby results in genetically impaired progeny. Today, sex sorted sperm is only commercially available in the bovine industry, due to the fact that bull sperm is more suitable for selection than sperm from other species.

The last couple of years the use of Internet has changed in the way that the web pages can be affected of the person that uses them. Because of this dynamic Internet technology has emerged that makes it possible for a web page to receive information from a web browser. This information can then be used to affect the appearance of the page. PHP and ASP are two dynamic Internet technologies. They are integrated in HTML and are executed on the web server.

A vulnerable group in society is people with ASD (autism spectrum disorders) or autism. This group seems to increase, mainly due to genetic factors but also environmental problems. Medical research has accelerated in the U.S. and Europe. The biggest problem for people with disabilities is the inability to communicate, both verbally and socially.

My objective for this project was to create a short but thrilling 2D-animation intended as promotion for an online comic book. The purpose of the project was to learn more about animation and graphics, to further my artistic skills and to learn how to work in Adobe After Effects. I also wanted to learn more about scheduling, project methods and how to handle stress. During the ten weeks of the project I have created the story, the storyboard, the character design, the backgrounds and the animation. The voice over was recorded with the help of a fellow student who also made the music and the sound effects.
