In the pilot plant at Hammarby Sjöstad, Sjöstadsverket, several new methods are tested in order to achieve a good use of resources. When a new technique is considered it is often the performance of the technique itself, under given conditions, that is evaluated. However, in order to evaluate the overall function the whole picture is needed. With a system analysis it becomes possible to make a comparison where all the positive aspects are put up against the negative ones, for the technique itself as well as its requirements. In this way the influence that minor components have on an entire system can be considered.This report presents a system analysis of an anaerobic membrane reactor (MBR) with a VSEP-membrane (Vibratory Shear Enhanced Process).

Forestry and forest products are vital components of the Swedish economy but the forest is also important for recreation, hunting, out-door life and conserving biodiversity. The Swedish Forest Act has two equally important objectives, production and environmental protection. Polytax is the Swedish Forest Agency´s inventory programme which monitors progress toward the two objectives in connection with regeneration fellings. It includes data on environmental protection measures taken in connection with regeneration fellings. 30 § of the Swedish Forestry Act and related regulations specify the demands for conserva-tion of nature.

VAV (Variable Air Volume) system has been studied in a newly constructed office-building. The goal for the study has been to evaluate how the ventilations system work in practice, if adjustments can be made to achieve an more energy efficient system and to evaluate if other alternative ventilation systems is to be preferred in the further.The degree project has been executed at Helenius Engineering Firm who is working with the environment, media systems, HVAC and energy in buildings. The building that has been studied is owned and operated by Akademiska hus.Literature studies, visits at site, inventory, review of system documentation, energy analyses, interviews, key figures, LCC, sand energy- and indoor climate simulations has been made to study the building. Where appropriate some tools from Six Sigma have also been used.How to achieve an energy efficient system and a pleasant indoor climate is studied with human health and well-being as base for the indoor climate requirements. Technical support systems such as ventilation systems have to be designed so that an acceptable indoor climate can be achieved.

Certification systems, that assess companies? work with social and environmental issues, have emerged in an increasing number of industries. Today, there are environmental certifications for the food industry, the forestry, the fisheries sector and several more. In apparel industry, certification for sustainable working conditions has been of major impact. The property sector is no exception from other industries.

Hydropower is the largest renewable energy source available in today's society. Operation and production is handled by high-tech electronics. This thesis is done on behalf of Statkraft Sweden AB who wants to explore the possibility of replacing the hydraulic cylinder with an electric actuator, generally as well as a case of a small power station on the river Nissan. Whether it is the chaplain or francis turbine vanes are actuated by hydraulic cylinders. Because of Gustavsberg hydropower is inconstant operation, this report is based on power calculations, which are read and computed according to the available hydraulic diagram.

The nitrogen cycle in freshwater bodies is complex and consists of many separate processes affected by a number of important factors for example oxygen concentration in the water, temperature and circulation. Knowledge of the different components of the nitrogen cycle exists; however, a complete and comprehensive picture is difficult conceptually as well as theoretically. The available literature illustrates that the research on nitrogen and the related freshwater processes is still associated with high uncertainty of how much of the supplied nitrogen from the catchment is transported with the water versus and how much is lost due to denitrification, sedimentation or uptake by plants. This report is an interdisciplinary survey of Nitrogen discharge permitting. The research focuses in particular on the decision-making process, the levels of scientific standard and the administrative framework.Application for Nitrogen discharge permits are decided by the Environmental Court with council from their own experts as well as relevant government authorities and organisations.

Problem: The relations between first and second tier suppliers within the automotive industry have changed drastically during recent years. Previously involving the supply of simple components, today the relation involves collaborative product development of complex subsystems. The situation is rather new for the actors, hence there are a number of problems that act as restraints for the collaboration. In order to come to terms with these problems, it is important to determine the underlying causes. Purpose: The purpose of this thesis is to make a survey of the main problems in the collaborative product development between first and second tier suppliers within the Swedish automotive industry.

Traditionally the content of fiction has not been described, analyzed, classified and/or indexed to the same extent as non-fiction. As a consequence, this lack of content analysis has resulted in unsatisfactory fiction retrieval in relation to users seeking and search behaviour. This fact is why this Master s thesis is written. The total of library users' seeking and search behaviour is investigated in order to suggest methods to improve user adapted fiction retrieval tools. Suggesting relevant fiction retrieval tools corresponding to users' seeking/search behaviour is another aim of the study.

Theory of mind involves the ability to take another person?s perspective in thought, emotions and intentions.  There is today a lack of instruments to assess children?s development of Theory of Mind (ToM) in Swedish. ToM is considered by many scientists to be the basis for development of pragmatic competence. The relationship between these two abilities is complex and not fully resolved. Both abilities are important components for the development of social skills.    The purpose of this study was to compare 4 and 5-year olds ToM-ability measured with a Swedish version of Wellman and Liu?s ToM-scale, Sally Anne and Social Emotional Test with estimated pragmatic competence measured with the Children?s Communication Checklist (CCC).

AbstractTitle:HelpTube: A Study on the Motivation behind Crowdsourcing with STD & Motivation Functions for Volunteer Work as Explanatory Models. Level: Bachelor Thesis in Business Administration; C-level. Authors: Honey H. Shahraki & Linnea M. Pira Supervisor: Jonas Kågström Date: 2013- June Background: In recent years the trend and usage of social networking has increased significantly amongst individuals as well as businesses.

Adjustment to acquired hearing loss can be understood as a process of learning and change where the point of departure is the subjective apppraisal of a person?s hearing loss in a social and cultural context. The aim of the study was to describe women?s thoughts, emotions and actions prior to audiological rehabilitation, since these are considered important for the ongoing process of adjustment and for the planning of rehabilitation. A phenomenographical approach was used in order to describe the variation in the women?s attitudes before attending rehabilitation.

The last couple of years the use of Internet has changed in the way that the web pages can be affected of the person that uses them. Because of this dynamic Internet technology has emerged that makes it possible for a web page to receive information from a web browser. This information can then be used to affect the appearance of the page. PHP and ASP are two dynamic Internet technologies. They are integrated in HTML and are executed on the web server.

The Swedish beef cattle population is growing when the dairy cattle become fewer. The fertility of the beef cows is important for the profitability in beef cattle production. Today there is no genetic evaluation for female fertility in Swedish beef cows. The purpose of this study was to see if calving interval can be used in the genetic evaluation as a measure of female fertility in beef cows. For this purpose the variation in calving interval for beef cows of different breeds and ages registred in KAP was studied.

The society of today is largely dependent on electricity and the dependence does not show any signs of declining. Reliability of supply will become increasingly important in the future and it is therefore important to investigate factors affecting the failure rates in electrical components.Sweden was hit by several severe storms during the 00?s. As a result of this many overhead lines in forests were cablified. In urban areas underground cable systems have been the norm for many years.

Background: Since1994, the EU NickelDirective is limiting the release of nickel from objects that are in prolongedcontact with skin. Despite this, nickel is still the most common cause of contactallergy in industrialized countries. This could implicate that other productswith short contact to the skin, which are not restricted by EU´s legislation inREACH (Registration, Evaluation, Authorisation and Restriction of Chemicalsubstances), could be a source of nickel or cobalt exposure. There is no limitfor cobalt release within REACH. To determine if there is cobalt or nickelpresent on the surface of a material and if metal can be released in contactwith the skin, there are quantitative and qualitative methods, such as the DMG(dimethylglyoxime)-test, the cobalt spot-test and a method for releasedetermination according to EN1811.Objectives: Laptops are not included in the REACH legislation.
