En studie av deltagardemokratiska experiment - trend eller verktyg?
The Swedish public inquiries and most of the political science advocate reforms in the spirit of participatory democracy to strengthen the democracy. Although it is striking how limited and narrow the scientific documentation is in analysing the effects of participatory democratic reforms. Still, many of the local governments in Sweden are reshaping their organisations according to the participatory democracy model. Is it a trend and a symbolic action or a veritable action of good-will of the politicians?The paper argues that the idea of participatory democracy has become popular and widely spread.
Styr- och beräkningsprogram för kalibrering av värmestrålningsmätare
Då det köptes in ny utrustning för kalibrering av värmestrålningsmätare till SP, Brandteknik, fanns det ett önskemål om att effektivisera proceduren vid kalibreringen. Vid kalibrering med den befintliga hård- och mjukvaran finns många manuella moment som skulle kunna reduceras.I detta projekt har ett styrprogram utvecklats i programmeringsspråket LabVIEW. Programmet använder ett seriellt kommunikationsprotokoll för att styra den kontroller som reglerar temperaturen i kalibreringsugnen. Programmet ställer in de temperaturnivåer som ska ingå i kalibreringen, upp till tio stycken, och kontrollerar när temperaturen har stabiliserat sig. När den gjort det tas ett antal mätpunkter ut och sparas till en resultatfil.
EAS-tagg med fuktsensor : Design och utvärdering av EAS-alarmteknologi för fuktdetektering
Electronic article surveillance (EAS) is widely used in shops and libraries together with an RF-tag attached to the goods or books in order to prevent shoplifting. By implementing the addition of a moisture sensor to the RF-tag, other functions become possible, including the ability to use as an alarm with regards to frozen goods, which have been shipped but which have melted and have, subsequently, refrozen. In- relation to care for the elderly, one time-consuming step involves checking whether there is the necessity for a change of diaper and this can, instead, be based on an RF-tag with an EAS-system alarm. A preliminary investigation was made using the moisture sensors, which involved how the resistance changes when liquid and/or heat is applied. A simulation of the LCCR circuit (RF-tag with the sensor) was conducted in order to determine how the resonance frequency changes for different resistances levels.
Energiåtervinning från gjuteriprocess till fastighet, undersökning för ökat utnyttjande av spillvärme
This diploma work on D-level is made in cooperation with Varnäsföretagen AB in Eskilstuna. The company performs contract manufactured aluminium goods. This work is a continuation on earlier diploma work in Varnäsföretagen AB. Even if the industry process consumes much energy for melting the aluminium goods, they consume a great amount of oil to warm up the building. The purpose of this work is to examine some places in the building and the process to see how much energy it is possible to recycles to the heating system and reduce the costs for heating.
Om sjukhusbibliotek i Sverige under 1930-talet ? en litteraturstudie av idéer om biblioteksverksamhet på sjukhus
The study concerns the history and development of hospitallibraries in Sweden in the beginning of the 1900 century.Focus is on the 1930 decade, the time of major expansionof the area. The study is based on study of literature, mainlyfrom articles but also from a few booklets from the time.The purpose of the study is to find out how the librarieswere described in the literature of the time and which goalsand tasks they had. It is also to make it possible to increaseunderstanding of the history of hospital libraries, using it asan inspirational source for development of today´s businessin a time of major change. The result of the study showsthat those goals and ideas are still valid and serve well as aninspirational basis for development of today´s hospitallibraries..

Planering för friluftsliv, biologisk mångfald och skogsbruk i skogsmiljö
Vallentuna municipality in Stockholm County, is planning to develop a management plan for a forest area owned by the municipality. The property is an urban forest and the hiking trail Roslagsleden runs through it. Hence the municipality intends to take extra care of the outdoor recreation interests, as well as forest biodiversity, but at the same time use the area for forestry. This study discusses how these three interests, recreation, biodiversity and forestry, differ in their views of how a forest should be managed, where they disagree and how they can coexist in the management of this area. In this study, a vegetation mapping of the area and an assessment of the forest?s conservation values was carried out.
Minor fieled study - molecular epidemiologi of rabies in Sao Paulo state and Minas Gerais state, Brazil
Rabies is a fatal zoonotic disease spread worldwide. The most common sources of infection
for all animals and humans are bites from dogs or bats. The aim of this degree project was to
diagnose and determine the source of infection for 11 rabies samples from São Paulo State
and Minas Gerais State, Brazil. Diagnosis was made through direct immunofluorescence
assay, mouse inoculation and RT-PCR. The sources of infection were determined by
sequencing 234 nucleotides of the 5? end of the N-gene and align these with homologous
sequences retrieved from GenBank.
Den lukulliske Lucullus' passioner; om villaträdgårdar, mat och ett romerskt orginal
AbstractFor this exam paper, I have chosen to delve into the life of Lucius Licinius Lucullus, the famous Roman general and statesman of the 1st century BC. Widely regarded as a glutton and degenerate, I will try to examine if these claims are true or completely exaggerated. My research will be based on the works of Plutarch, the great Greek scholar and biographer, who's our main source of knowledge regarding the life of Lucullus. Furthermore, I will examine two of Lucullus's main interests ? his love for villa gardens and culinary delights ? to see in what way they have contributed to the common picture of him as a sybarite.
Framtagning av reläskyddsinställningar för en transformatorstation
A substation must be properly protected against lightning and other external effects to the equipment in the station or staff, for that we use relay protection. They should also protect against internal errors which may occur as ground faults. There are different types of protection relays, but most common are overcurrent-, distance-, residual current- and differential protection.The purpose of this thesis was to deepen our knowledge of relay protection and to use the theoretical knowledge we got from the university studies in the work process. In the process we discovered which parameters were the most essential and calculated these for all relay protections on the substation. We also carry out a comparison between two brands of relay protection, ABB and Alstom.During our work we will test and simulate the over-current relays in a program called NEPLAN, the program will also calculate the fault currents.

MUSIK TILL GUDS ÄRA - SYNDIGT ELLER GOTT? : En studie av kvinnors musicerande i den tidigkristna kyrkan
This thesis aims to investigate and discuss the possibility for women in the early Christian church to make music, which in the ancient Roman society was something complicated. Afemale musician was looked upon as decadent and dissolute. This idea, in combination with the music ideals of the church influenced by the Neoplatonic movement, and the Pauline statement (1 Cor. 14:34-36), cast women to be completely prohibited in participating even in the psalmody during the service. My purpose is to discuss how this was looked upon in different Christian regions, using the church fathers as the main material source, since this has not previously been well documented or studied..
With a few liters of clean drinking water : a Cost Benefit Analysis of the socio-economic effects from implementing new clean drinking water technologies in rural India
In 2010, Airwatergreen AB started testing their new technology, the Airwaterwell, an atmospherical water generator of their own design that is running on solar heat, with a production capacity of three litres of water per day and m2. The purpose was to focus on foreign aid organizations as main purchasers for project investments towards rural communities in developing countries that suffer from lack of, or compromised quality of drinking water. In order to further understand if this technology would bring a positive impact in the developing countries, the company contacted the Swedish University of Agriculture for a socio-economic study of the Airwaterwells? potential.
The authors elected Cost benefit analysis as the appropriate method for conducting the study and India became the study region because of its many problems with water related issues such as diseases as well as insufficient water supply for households. The regions that this study is based on are Gujarat, Haryana and Uttar Pradesh given their differences in income, health situation and poverty rate.
The state of the Latvian wood pellet industry : a study on production conditions and international competitiveness
In the last decade, member states of the European Union have adopted a range of measures to decrease the dependency on fossil fuels. This has led to an increased use of biomass in heat and power production. In some countries, the lack of forest resource has led to large scale power producers importing their biomass needs. Due to high energy content and homogeneity, wood pellets have become an internationally traded commodity used for large scale power production.
The Baltic States have emerged as one of the largest wood pellet exporting regions in Europe.
Textila cylindrar - experiment kring solljusreglering
Working with a three-dimensional shape that adjusts light seemed exciting. Venetian blinds became a basis and source of inspiration in my project. What is a Venetian blind? I arrived at the de?nition ?a surface of angleble pieces for sun adjustment?. From that simpli?ed meaning I started making sketches of what an alternative model could look like.
