Rening av metallhaltigt avloppsvatten : En teknisk/ekonomisk utvärdering av reningsmetoder för metallhaltigt avloppsvatten
This Master?s Thesis aims to investigate and assess the methods used to decrease the discharge ofmetals, primarily copper, from the water purification plant at Assa Industries plating factory inEskilstuna.Literature studies of the purification methods precipitation, ion exchange, evaporation, reverseosmosis and electrolysis has been done to appraise the adequacy of the technique. Thesetechniques are commonly used for purification of industrial waste water.Assa has four plating lines: the Trumline, the big Zinkline, the new Zinkline and the Decorativeline. The new Zinkline is the most modern of the four lines and purification is done byrecirculation over an ion exchange unit. The demand for fresh water is thereby heavily reduced.The Trumline, the big Zinkline and the Decorative line all use older techniques.
Uttagsbeskattning och beskattningsinträde : En analys av förenligheten med etableringsfriheten
AbstractEver since Sweden joined EU Swedish law has to be compatible with EU law. Swedish law cannot state anything that may restrict the freedom of establishment. This means that companies are free to change their resident within the EU without any restrictions. National rules regarding exit tax states that companies who wants to move their business out of Sweden is taxed as if their assets has been disposed of at the exit time. These rules have been found to restrict EU law according to case RÅ 2008 ref 30.
En iPad-baserad ritningsbehandlare
In today?s society, it becomes more common with tablets, that makes us interact with computers in a whole new way. For example these are used to read and write e-mails, surf the web and playing games. Another manner of use of these tablets is to read and edit PDF documents. PDF handling is often meant to be used in books and inregular text documents, but it could also be used in the management of drawings.An industry that would benefit greatly from the use of tablets for this purpose is the con- struction industry.
Webbens klassifikationssystem. En komparativ studie
This thesis deals with subject-based hierarchical search-services on the World Wide Web. The purpose is to investigate how systems of this kind facilitate information retrieval through subject-based information seeking. Its starting point is taken from the study of texts and qualitative analyses of search-services on the World Wide Web. Important aspects and features of the Internet and the World Wide Web are explained as well. Three systems are examined: Mölndals Stadsbiblioteks Länkkatalog, Svesök, and Alta Vista.

Navigering, koordinering och översikt
The advantage and the possibility of keeping track of a number of vehicles to
make work practice more effective and smooth is today a favorable choice for
Visual Units Logistics customers. We?ve been evaluating the software and trying
to take it one step further and letting not only the individual user, but
maybe, the company as a whole benefit from its advantages. This has been done
by using methods like letting ourselves get to know the software, user case
studies, workplace studies, interviews and future workshops. This resulted in a
prototype introducing a new function designed with all collected data in mind
trying to make the software, Visual Units Logistics, even more effective for
the every day work practice of the user.
A new function to keep track of vehicles outside the main working area at the
same time as you still can keep track of the other vehicles in the field..
Utspelstratt och nyhetsjakt ? en kvalitativ intervjustudie av relationen mellan journalister och politiker/pressekreterare
In this study we have explored and investigated how journalist experience the relationship with politicians/press secretaries in the making of political news. The study examines how journalists see the balance of power between them and their political sources in the setting of the news agenda. To do this we have used a qualitative interview analysis. Our theoretical starting points have been based on the social exchange model. The social exchange model has a social psychological and sociological perspective that explains the interaction, social exchange and stability as a process of negotiation exchanges between parties and operators.
Utvärdering av CTI på virkesfordon : ? CTI-projekt Holmen Skog/Örnfrakt 2005-2006
The low bearing capacity of roads during the spring thaw and periods in the autumn leads every year to increases costs for Holmen Skog. To reduce costs and increase accessibility
Holmen Skog decided to install and test a CTI-system. Central tire inflation (CTI) is a system that makes it possible to monitor and vary a vehicle?s tire inflation pressures from the cabin, while the vehicle is in motion. When tire pressures are reduced, the area of the contact surface between the tire and the road increases, thus reducing the ground pressure.
The purpose of this study was to evaluate the CTI-equipped vehicle and analyze if the CTI technology is economical defensible during the thaw 2005.

Jämförelse av två mätmetoder för mindre gasvolym
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.

Råvaruinflöde inom träindustrin : En fallstudie på ett norrländskt pappersbruk
Today's global market means that raw materials are sought and bought from all over the world. This creates an higher demand for a well-functioning supply chain. In our thesis we have studied a large paper mill in northen Sweden which experiences issues with flow of raw material. Our aim has hence been to examine which aspects affect the flow of raw materials to the mill, and how these can be adressed using an IT-system. The question we sought to answer was; What factors are important to consider and how do these affect the ability of an IT-system which will support the flow of raw material at the paper mill? We have found that the problems are strongly connected to the low amount of information sharing between the mill and the suppliers.
En analys av centralkylan i Slakthusområdet i Stockholm
In Stockholm, Johanneshov the Slaughterhouse area (Slakthusområdet) can be found. A number of companies have gathered there providing the Stockholmers with meat products. This area has a great need for cooling to supply large cold storages. To facilitate this, a central cooling system has been built, supplying the area with effective and safe cooling.The aim of this master thesis study is to give hints to energy efficient and reliable changes that can be put in place at a low marginal cost depending on the future activities in the area. The suggested changes will be presented to the company Bravida (managing the system), which also desires a deeper understanding of the energy flows through the central cooling system.Firstly visiting the site with proper guidance, we have then tried to understand the function of the system including which machines and media that are used.
