The most common way to treat wastewater in Sweden today is by a combination of an activated sludge process and a chemical treatment. These processes are not very energy efficient and may not be the most environmentally friendly. That is why it is interesting to evaluate new alternative methods to see if they can be less harmful to the environment and help to a lower resource consumption. New techniques are tested in a pilot installation at Hammarby Sjöstad, Sjöstadsverket. To be able to evaluate these techniques in a wide perspective system analyses are conducted where different impacts can be considered, advantages and disadvantages in the systems.Five system structures for water treatment have been constructed in Matlab/Simulink in this study.

There are around 855 000 on-site sewage systems in Sweden and some 1 800 of these are located in the municipality of Sigtuna. The Sigtuna local authority has set the goal that all sewage systems with insufficient function should be improved before the end of year 2010. A malfunctioning on-site sewage system may cause three main problems: spreading of diseases, discharge of eutrophicating compounds and wastage of resources. The municipality strives to reduce these problems already at the stage of granting permits for installation of on site sanitation systems. The municipality has recently adopted new guidelines, which demands certain minimum reductions for different compounds. The guidelines also state that it is preferred that neighboring house-owners cooperate in jointly built and operated sewage systems and that the system should be able to recycle plant nutrients.

Blekinge Hospital suffers from a budget shortage of 100 million SEK, while the government now requires that hospitals will no longer be running a deficit. Blekinge Hospital will then use their limited resources to survive in the future and the activity must be enhanced in order to keep costs low without having to lay off personnel. The idea is that the organisation should be more efficient with a more efficient resource usage. Performance measurement systems are important tools for achieving the policies set out within an organization, measuring and evaluating performance is a way to see where improvements in efficiency may be necessary in the business. Balanced Scorecard (BSC) is one of several measuring systems, where the focus is on measuring non-financial performances.

The demand for food, feed, fibre and fuel has increased in Uganda over the past 50 years due to population growth. Recurring extreme climate events such as drought and flooding, in combination with large-scale land degradation, have led to declining crop yields. Lack of equipment, money and socio-economic issues has contributed to low yields. However, the soils in Uganda have the potential to produce much higher yields than they do today. This study, which was carried out in April-June 2013 in Kkingo District, south-east Uganda, examined the effects of agroforestry on yield of cooking bananas in small-holder farming systems. Six farms practising agroforestry and six farms with no agroforestry, which were chosen in cooperation with the NGO Vi Agroforestry, were compared.

Non-compulsory schools in Sweden should make use of the knowledge and experience that is available in society according to the aims and objectives of the Curriculum for the Non-Compulsory School System - Lpf 94. There are however only a few studies which have focused on the contacts between non-compulsory schools and society as represented by the business world in Sweden.The purpose of this study is to examine in what ways and to what extent non-compulsory schools are following the Curriculum by using the knowledge and experience of the business world. The perspectives have been: Which contacts in the business world and which working practices from the business world are implemented in teaching in non-compulsory schools? In what way do these contacts and working practices affect the teaching and learning of business administration? The purpose of this study is also to examine if the teachers in non-compulsory schools use business information and different kinds of business knowledge and experiences in order to keep themselves up-to-date regarding the business world. The perspectives have been: Are the teachers using up-to-date business information or business experience? Are the teachers applying a multicultural perspective in teaching business studies? In what way does this kind of information or first-hand experience affect the teaching and learning of business administration?The method used in this study was to interview seven teachers from two non-compulsory schools in Stockholm.

More frequent and intensified rainfalls are expected to occur due to climate change in the nearfuture. This together with a higher proportion of paved areas increases the pressure on today?sstorm water systems (Risinger, 2014; Boverket, 2013; Stahre, 2006). Traditional storm watersystems (i.e. underground pipe systems) have during last decades started to be questioned(Olshammar & Baresel, 2012).

The effectiveness of communication in the Swedish healthcare system context has long been the subject of debate. Issues stemming from usability, accessability and interpretation affect the lives of patients, and yet the vocal groups in the healthcare communication debate are patients and administrators, not healthcare professionals. With the advent of eHealth services and new demands being put forth on the ability of healthcare professionals' to handle increasingly numerous and innovative systems, it is of more importance than ever to understand the healthcare professionals' work context. This article is based on interviews with five healthcare professionals concerning their views on electronic health records (EHR), eHealth services, trends in healthcare services development in Sweden, as well as their views on the future of eHealth solutions and health information technology (HIT). Analysis of collected information shows an apprehension among healthcare professionals towards electronic communication, as well as a dissatisfaction with the usability of modern healthcare systems.

While studying at the landscape architect program in Uppsala I found stress to play a major roll in the education. To help myself and others to handle the negative stress within the profession and the education I choose to write my thesis about landscape architects' work cultures. Swedish Association of Architects is in second place in the SACO study on long-term sickness for fatigue syndrome, stress and depression. The issue needed to be addressed. My purpose with the thesis has been to study the work cultures in the landscape profession and training and to study and find ways to manage negative stress in the profession and in education.

Article 4.1(h) in the Rome I regulation establishes which law that will be applicable on contracts concerning financial instruments concluded in multilateral systems. The main problem is that most contracts concluded within these systems have standard clauses which contain a clause on the applicable law. If this is the case, Article 3.1 in the Rome I Regulation is applicable instead. This problem makes it difficult to find a need for article 4.1(h) if it will only be applicable in exceptional cases. However, the legal position on this matter is still unclear since the Rome I Regulation has just been put into force.

The purpose of this project is to analyze earthing systems for houses. By practical measurements and theoretical analyzes consequences of possible faults, that can occur within the facility and in the low-voltage distribution network, is illustrated.  The reason for this project is that nowadays one has to arrange with a main equipotential bonding system for buildings. Apart from that, if necessary, bathrooms must be provided with a supplementary equipotential bonding system.The practical measurements verify that potential differences in facilities may be due to voltage drops in the PEN conductor between the origin of the electrical installation and the power transformer.Based on the theoretical analyzes of possible faults, it is considered that the requirement for  supplementary equipotential bonding systems for bathrooms in most cases can be questioned, when basic insulation, fault protection, residual current devise and main equipotential bonding system already provides an adequate level of protection.A PEN conductor loss may result in a situation where metallic parts attached to the equipotential bonding system starts working as earth electrodes. Equipotential bonding system may also increase the incidence of stray currents. If TN-C-S systems is provided with a local connection to earth a redundant system against PEN conductor loss is obtained.

At the end of 70s and the beginning of 80s, 18 terminals was built and used for chipping wood residue from clear cuttings. Most of the terminals was terminated before the 2000s but with the high oil- and energy prices that we can see today there might be a place for these terminals again. The goal with the study was to analyze and compare economical differences between 5 different logistical systems, collected data was used with a set of formulas. The systems include long range transport of slash, chips and bundles. Three of the systems include transport by lorry to industry the last two includes a terminal with access to train transport.

With the advance in computer and network technologies, multimedia systems and Internet applications are becoming more popular. As broadband network is prevailing, more clients are able to watch streaming videos or to play multimedia data over the Internet in real-time. Consequently, there is an increasing demand in the Internet for streaming video systems. As the run-time environment of such applications tends to be dynamic, it is imperative to handle transient overloads effectively. The goal of this work is to develop an algorithm that would provide a robust and controlled behavior of the video system so that important data is delivered on time to the video clients.

Anbudsprocessen på Balfour Beatty Rail i Västerås står inför en förändring då man vill införa ett nätverksbaserat kalkyleringssystem. Examensarbetets avsikt är att fokusera på anbudsprocessen med fokus på kalkylarbetet för att se hur dessa kan effektiviseras, samt för att se hur arbetet med kalkyleringen ska utformas på bästa sätt vid övergången till den nya plattformen.För att komma fram till hur anbudsprocessen ska kunna förbättras och designas på bästa möjliga sätt har detta bland annat lösts med hjälp av semistrukturerade intervjuer med alla som är involverade, för att få en insyn in i processen på en detaljnivå som tillåtit mig att modellera processens utgångsläge. Då företaget har utryckt en önskan om att ?skapa en ?lean? anbudsprocess? har målet varit att förbättra processen med hjälp av den teori som är tillämplig (operations management, TQM, MIS, project management med mera) samt även att underbygga den med teori om lean enterprise och undersöka möjligheten för ett större åtagande av ett lean system.Efter undersökande av processen har en rad förbättringar föreslagits som till viss grad kunnats illustreras med en ny processkartläggning. För att optimera organisationens arbete med att producera anbud har det konstaterats att beslutsprocessen som leder fram till ett åtagande av produktion av anbud varit för lång och behöver effektiviseras genom att bland annat förbättra beslutsunderlaget innan ledningen träffas, att korta beslutsvägar och att ha möten minst två gånger i veckan.

In this project we have used the theory of analytical mechanics to derive equations of motion for complex mechanical systems in order to study their behaviour over time. Even if the theory provides powerful tools to tackle tough problems which would be very hard to solve by methods of Newtonian mechanics, you are still relatively limited without running any computer simulations. One realises that in a faster rate it will be an incredibly difficult task to find an analytical solution when the degrees of freedom increases. Even if one would succeed to derive the equations, one still has to solve them to get the information of the systems behavior. Of experience one knows that the equations in general are nonlinear and hence must be integrated numericaly.

The field of the social economy and of the work integration social enterprises (WISE) in particular, is for many a more or less unknown area. Unlike ordinary enterprises the WISE's are different due to their aim of integrating disadvantaged people through work. In comparison with other small enterprises earlier research has shown that the WISE's are dealing with challenges regarding recruitment, participation, leadership, sustainable business ideas but above all, the access to funding. The purpose of this essay has therefore been to examine and analyze the financial situation of eight WISE's located in the Stockholm County. The results indicate that half of the enterprises perceive their economic situation as very unstable and as an obstacle to their further development.
