The purpose of this essay was to study social workers´ and polices contributions with criminal youth gangs and get an insight in how co-operation in the contributions between these governments comes to rank and works.To find out, we carried out a study with a qualitative design based on document studies and interviews with social workers´ and polices who were meeting youths in their work.Our findings were that it's hard to define a criminal youth gang. The social workers´ and polices have both individual and common contributions with criminal youth gangs. One of their most important lining is to prevent new recruitment of young people to criminality. The social workers´ and polices both have an intention to cooperate but they can?t agree about the method of work they shall use, ?the kid-glove or the whip?..

The aim of this study is to find out in which way the education about climate in school is taught and how the students experience the world situation today. There are various theories about the greenhouse effect and its origin and these theories should be addressed to ensure that students get a broader understanding of how climate change occurs. This includes the natural phenomena and also the human impact on climate change. Students in school are a source of concern that only human are the cause of global warming, and know little or almost nothing about the natural phenomena of global warming.  I will mention what has emphasized in the national steering documents in the case of environmental education at school.I have used a qualitative method, where interviews and document analysis were used as techniques. The interviews took place with five students in ninth grade and with three science teachers in the same school..

The environmental requirements and laws on combustion engine emissions are very tough today andthey will become even more stringent in the future. To achieve these requirements there are highdemands on the control systems for these engines. An improved precision in the measurement of anengine's speed and position gives the electronic control system an even better timing when it comes tofuel injection and ignition. This makes the engine more fuel efficient, reducing the emissions. This thesisis part of a collaborative project between Hoerbiger Control Systems and subsidiaries.

My aim is to provide knowledge about ways of understanding Intranet as a communication artifact. Today organizations plan to update their technology so as to make the communicative functions of Web 2.0 come true. With this objective in mind organizations will be prepared to meet social demands among staff. After interviewing intranet managers I have compiled qualitative data in categories. My approach is influenced by a phenomenographic approach.

Examensarbetet har gått ut på att uppgradera ett styrsystem och en operatörspanel för en centrifug i en kemisk industri. Projektets syfte är att centrifugen ska köras på ett mer automatiskt sätt med ett nyare system som har större tillgång till reservdelar.          Centrifugens äldre styrsystem från Siemens har bytts ut mot ett nytt Siemenssystem och den tidigare operatörspanelen från Siemens har bytts ut mot Beijer Electronic E1070 operatörspanel. Styrsystemet programmerades sedan i Siemens Simatic Step7 och operatörspanelen programmerades i Beijer Electronics E-designer.                Efter att programmeringen var klar testades kommunikationen mellan styrsystemet och operatörspanelen innan inkopplingen av det övriga systemet skedde.

An organization that uses all of its improvement opportunities has a great advantage compared to its competitors. It is an important task when it comes to continuous improvements of every process. Up until September 2007, Husqvarna AB had a suggestion committee who evaluated every suggestion separately and the proposer received a payment if the suggestion was approved by the committee. However, this system did not work satisfying enough to fulfill Husqvarna?s needs and they are now looking for a system that can handle the ideas from the employees in a more effective way.

Quadrotor UAVs are self-stabilizing, autonomous flying machines that has recently become more popular than ever. Unmanned Aerial Vehicles have their roots in the military, where they were developed for use in reconnaissance and combat. During the last few years, advances in the fields of electronic sensors, electric motors and microcontrollers have enabled smaller designs and autonomic flight control even for private use. The quadrotor, which is the particular kind of UAV we are looking closer at in this paper, has 4 rotors in an X-like formation. This configuration has many advantages such as good lift capacity, non-complex mechanical structure and serviceability.In this project we aquired a current overview of the domain and determine whether it is possible to construct a quadrotor UAV designed for use in a WISENET sensor network on a low budget and short time schedule.Based on existing community project AeroQuad, a quadrotor is constructed with a budget of about 500 euro.

Brominated flame retardants (BFRs) has for many years been used in products to reduce their flammability, mainly in electronic products, textiles and construction materials. In 2003, Sweden imported 300 tons of brominated flame retardants. Leakage of these compounds has polluted natural environments. Fishes has shown increased contents of these substances, especially fat fish, since brominated flame retardants tends to accumulate in fatty tissues. They are also regarded as persistent and that gives them the ability to travel long distances. What also is really scary is that increased levels of brominated flame retardants have been detected in human breast milk. The knowledge of the brominated flame retardants is limited and not so much research has been done in this field. There are many reasons though, to keep the research going. Partly their structural resemblance to well-known toxics as PCB, but also their ability to accumulate in biological systems and enrich in food chains. In which way they affect humans we really don?t know yet.

The purpose of this report is to document the experiments carried out, methods used and results gained during research into how the silicon content of an aluminium alloy affects the coefficient of thermal expansion (CTE).The goal of this paper is to better understand and to find a relation between silicon content and the coefficient of thermal expansion.Experiments were carried out using carefully prepared samples of Al Si alloys (0, 7, 10 and 20% Si content). Using these alloys, the CTE could be measured using a dilatometer.Comparative analysis carried out could map the effects of silicon content on the coefficient of thermal expansion and an equation was created. Using simple graphs and the rule of mixture method, the authors were able to build a simple tool for calculating the CTE of specific aluminum silicon alloys..

Uppsatsen är skriven med utgångspunkt i att understödjande förbands bidrag i operationer i stadsmiljö sällan nämns i reglementen, samt att förståelse för hur telekrigsförband uppträder och deras unika förmågor är generellt sätt låg inom försvarsmakten. Mitt syfte är att tydligöra hur en telekrigsenhet med dess unika förmåga kan bidra till lösande av uppgifter i en MOUT-operation. I min uppsats försöker jag med hjälp av ett teoretiskt synsätt svara på vad en telekrigsenhet kan bidraga med i en operation av ett MOUT-koncept. För att besvara denna fråga använder jag mig av en kvalitativ textanalys och intervjuer. Resultatet som framkommer är att en telekrigsenhet är en unik resurs som kan bidra med unika underrättelser och verkan, främst kopplat till stegen förstå, få bättre lägesuppfattning samt att kunna engagera motståndaren i en MOUT-operation..

Two different methods for measuring biogas production were used, gas meter and gasbags. The gas meters were electronic and counted each time a certain gasvolume passed through them. The gasbags collected the gas that hade passed through the gas meter until a manual measuring could be done. The two different methods gave the same result for a volume at three liters but for a volume around 0,2 liters they did not. Accuracy and precision for the gasbags was more exact than for the gas meters even if the method was difficult with a lot of different elements that could affect the result.

During the period of occupation of Norway between the years 1940-1945 the National Lutheran Church took the responsibility of supporting the Norweigans in their ideological battle against the Nazis. This was a period named Holdningskampen in Norwegian history. One person to remember was Eivind Berggrav, bishop in Oslo diocese. He was the one responsible for the theological document of importance Kirkens Grunn that became important as a document against the Nazis and the small percentage of Christians that related to the naziinspired-church. Berggrav was also one of the founders of Den Midlertidlige Kirkeledelsen, the organisation responsible for the non-nazified churches.

Speedledger is a company that is working to automate electronic accounting for businesses, organizations and associations.In the current situation bank data is sent from the users internet bank to Speedledger via a virtual printer driver. The driver transforms the web page into a PDF and sends it to a server for interpretation.The problem is that PDF is not created for this sort of data transfer and makes the interpretation of data is very problematic.The goal of the thesis is to study whether there is a possibility to develop a browser add-on that can retrieve information on the customer's banking page and send it on to Speedledgers server for interpretation. My task was to implement a add-on for one of the three major browsers Mozilla Firefox, Google Chrome or Microsoft Internet Explorer, and then study the possibility of implementing it to the other two by reading the documentation.What I concluded was that it is possible to implement for all the three browsers. However, the techniques will differ slightly when developing these add-ons.  .

I dagsläget finns tydligt regelverk som anger hur byggnader skall uppföras, dock saknas hjälpmedel för att kraven skall anses tillgodosedda på stora och komplexa byggnader som finns inom industrin, skall dimensioneras för att tillfredsställande brandskydd ska uppnås. Detta resulterar i att analytisk dimensionering (dimensionering baserad på uträkningar till skillnad mot förenklad dimensionering vilken i princip följer de allmänna råden) som regel måste användas även vid mindre byggnationer. Syftet med examensarbetet är att påvisa eventuella oklarheter i det existerande regelverket (Boverkets byggregler, BBR) 1 för brandskydd av industribyggnader i Sverige, där reglerna för förenklad dimensionering inte är anpassade för byggnader med industriell verksamhet. Målet är att om möjligt komma fram till hur man skall resonera vid dimensionering av brandskyddet i dessa byggnader utifrån en diskussion om rådande lagstiftning och de skillnader som påvisats mellan Sveriges och andra länders regelverk. Arbetet består av en litteraturstudie av de regelverk som finns för brandskydd i Sverige, där de avsnitt som är problematiska för industribyggnader lyfts fram.

En snabb och ständig teknisk utveckling leder till att företag och andra organisationer kan ta del av nya tekniska verktyg, som sedan kan användas i verksamheten. Till följd av detta möjliggörs nya sätt att kommunicera information och göra affärer på elektroniskt. Detta område kallas elektroniska affärer och får allt större utrymme idag, men vad är det egentligen som gör att ett företag intresserar sig för det?Elektroniska affärer är ett stort och komplext område som ofta kan innebära stora förändringar för ett företag. Att eventuellt strukturera om och förändra arbetssättet kan vara något som ses som lite skrämmande för en del företag och därför kan det uppstå problem med att se de positiva effekterna.
