The change in the information society has affected the development of the labour market for information specialists and informants as well as their roles. Companies are now aware of the fact that information specialists have a variety of important skills and competence that is important for them. The goal of this thesis is to see what defines an information specialist and an informant and also to find out their situation on the labour market. The similarities and differences between the two professions will also be discussed in the thesis. The main method used is the investigation of the job advertisements in the journal DIK-forum from the year 2000 and year 2004.

The idea for the project emerged when Nilorn wanted to get better control over their supplychain and improve operational efficiency. The company also want to reduce their expenses inthe continuous process of improving profitability. By choosing the right option oftransportation and mode of transport there are large potential savings for the company. Thisenables Nilorn to reduce the transportation costs and strengthen the environmentalresponsibilities by reducing their environmental impact.The flow of goods within Nilorn has over the past years increased significantly and most ofthe gods today is transported by air. The aim of this thesis is to analyse the supply chain of thecompany and evaluate the potential economic savings in this area.

Högbytorp is Ragn-Sells? largest waste facility and it is located north of Stockholm. There is an old landfill still in use, but at the end of this year it will be closed. The waste deposited on the landfill can, through decomposition, give rise to a large amount of methane gas, which is an energy rich gas that can be used for heat and electricity production. To receive a relatively large amount of gas, the decomposition requires a high moisture content in the waste.

About 30 % of our greenhouse gas admission comes from the food we are eating, and food plays a crucial role in the choice of destinations. The tourism industry has a great opportunity to affect our food habits. Used in the right way, the industry can teach us to eat more environmental friendly..

The objective of this diploma work is to investigate a set of Multiple Input Multiple Output (MIMO) channel models compatible with the emerging IEEE 802.11n standard. This diploma work validates also advanced, innovative tools and wireless technologies that are necessary to facilitate wireless applications while maximizing spectral efficiency and throughput. MIMO channel models can be used to evaluate new Wireless Local Area Network (WLAN) proposals based on multiple antenna technologies. The purpose of this thesis is to investigate means of channel models and their implementation in different environments such as: Matlab, C++ and Advanced Design Systems (ADS). The investigation considers also a comparison between the channel models based on theoretical data and parameter setup to the channel models based on statistical characteristics obtained from measured data.

In the wake of a heightened interest in the Swedish Middle Ages, the need for knowledge has increased as well. The Swedish Middle Ages was an era when the country truly began to grow closer to the European sphere of culture. The forces behind this transformation are largely to be sought among the social elite, the budding aristocracy of Sweden. The process of becoming ?Europeans? brought with it great changes to Sweden, not the least in terms of the political arena.

Mobile devices such as tablets and smartphones are quite common in this day. The author of this thesis wanted to know how common these mobile devices are in the building industry and how they are used and what potential an app could have. The author thus conducted an investigation on this matter, mainly in the form of interviews.Answers given by the interviews were then used as a basis to survey the usage of mobile devices and the usage of different kinds of apps. An investigation of different apps with the potential to be used by professionals in the building industry has been carried through. Apps which manage such things as scanning documents, measuring distances and handle communication.

The concept of national security has been a matter for debate during recent years, especially in academic fields. Criticism has surfaced since the end of the cold war, directed towards the traditional perspective's dogmatic focus on armed threats and interstate war. Questions concerning an oncoming paradigm shift have been raised, regarding a widening of the security agenda among national states to also include alternative threats, such as environmental hazards. In this thesis, the focus lies on the effects that climate changes have caused in the Swedish national security agenda during the last 15 years. Swedish policy documents show that there have been some major changes, not only the widening of the security agenda but the entire security domain seems to have changed.

This report is focusing upon relining from a client?s point of view. Potential buyers are given a presentation of the different methods available today together with a general briefing describing the process. An important part of this report are the interviews that took place with already established customers. Property owners, managers, pipe cleaners, and project managers whom all been in contact with relining have answered the questions given along with their own thoughts and have also given recommendations of other persons to talk to.

The EU's Water Framework Directive aims to a long-term and sustainable use of our water resources and wants to ensure good water quality in Europe's water bodies. Discharge of polluted stormwater into receiving waters can be a threat to their ecological and chemical status. Municipalities are responsible for supervision of the environmental quality standards (EQS) and therefore need to gain knowledge of current stormwater management, the expected level of pollution emissions and possible appropriate purification steps to ensure that the goal of good water quality is achieved.This master thesis aims to provide this knowledge in the example case of Vallentunas urban area and wants to prepare future oversight so that it can be assessed how much the discharge of polluted stormwater into the local receiving water is a threat to its status. With the help of maps, aerial photographs, site observations and individual discussions those areas are mapped where appearance of moderate to highly polluted stormwater could be suspected. The degree of pollution at the discharge points is determined based on land use upstream and uses standard values according to the administrators assistance "Tillsyn av dagvatten" (MSL 2014).The study identifies 100 areas in need of supervision regarding their stormwater management.

Abstract The benthic macroinvertebrate fauna of 22 natural springs on Öland was sampled, by using a time-standarized kick/sweep sampling technique, in the end of September and early October. The aim was to determine the number of species and their abundances in the macroinvertebrate communities in springs and how/why these may change between different springs. Likewise there was a purpose to investigate possible differences between springs considering the proportions of the number of species and the abundances of the five functional feeding groups; shredders, collectors, filter-feeders, scrapers and predators. There was also an aim to investigate if the distances betweeen springs had any influence on similarity between the communities of benthic macroinvertebrates of the springs. Analysis from the springs collected material showed several interesting patterns in the number of species and their abundances when compared between springs devided into groups depending on their environmental factors such as depth and pH.

The last decades have shown increased nitrogen leeching from soil to water recipients. This is inSweden mainly due to over-manuring of agriculture land, effectivization of drainage systems and thedeclining extent of wetlands. The accumulated amount of nitrogen in water doesn?t only make itunsuitable for use by humans and cattle, but also decreases the biological diversity as well as negativelyaffect tourism and fish industry. In the most severe cases shallow maritime grounds can be completelydepleted of oxygen due to decomposition of the increased amount algae and plankton growth.This study have the aim to describe and quantify the nitrogen leeching from the Genevad drainagebasin, located in southern Halland, Sweden.
