Nya tillämpningar för utandningstest kopplade till Kibions diagnostikinstrument IRIS®

The aim of my thesis is to obtain knowledge of textile wastewater and textile sludge from an environmental perspective, which can be used as a basis for the  ?Sweden Textile Water Initiative? guidelines for a sustainable sludge management. In my study I have mainly focused on textile dyes, salts and metals and their routes during wastewater treatment.This paper is partly a literature review, which I began by identifying the pollutants discharged from each textile process. Then I studied wastewater and sludge quality, environmental aspects, possible treatment and recycling methods. I have also tried to find existing type of guidelines in order to make comparisons.

Soil carbon in small-holder plantain farms, Uganda : a comparison between agroforestry and non-agroforestry

Smallholder farmers in Uganda suffer from declining productivity. With a rapidly increasing population, marginal land is taken into production and the current land management leads to loss in soil fertility and escalation in soil erosion. There are studies indicating that the use of agroforestry increases soil organic carbon (SOC) compared to systems without trees. Soils which are high in carbon have many advantages, for example better water holding capacity, which can reduce stress on crops during drought. The aim of this study was to determine the effect agroforestry has on SOC concentration in small-holder farming systems in Uganda. The intended system to study was farms practicing agroforestry methods or not in intercropped plantain (cooking banana) fields.

Företagsförvärv ? Värderingsprocessen för svenska investmentbolag

Det har blivit allt vanligare att köpa och sälja företag vilket gör att företagsanalys väcker stort intresse bland revisorer, investerare och analytiker. Syftet med denna studie är att beskriva hur professionella analytiker på investmentbolag i praktiken arbetar inför ett företagsförvärv. Detta kommer förhoppningsvis mynna ut i större förståelse för hur förvärvsprocessen tillämpas i verkligheten. Studien kommer att fokusera på hur värderingar genomförs tills dess köpet är avslutat. Frågan som studien ska besvara är; Hur ser förvärvsprocessen ut för svenska investmentbolag fram tills dess köpet är genomfört?Studien använder sig av en kvalitativ metod och har genomförts med hjälp av intervjuer samt ett beskrivande företag.

Självkompakterande betong vid platsgjutning av anläggningskonstruktioner

By using modern methods of casting concrete, cast in place can get more effective and industrialized. A modern method is self compacting concrete. By using this type of concrete, advantages like improved working environment and rationalized construction can be reached. Because the concrete doesn?t need to be vibrated, the amount of staff on site and the noise can be reduced.

Värderelevansen av Dirty Surplus Accounting Flows i Svenska Storbolag

Since the implementation of the revised IAS-1 in January 2009, the income statement has changed in order to include what is called dirty surplus accounting flows (DSF). Using data for the period 2005-2009 regarding large cap companies listed on the OMX Stockholm we identify DSF in Swedish accounting. First, we present some descriptive statistics on aggregated and individual DSF in Sweden. We find that aggregated DSF and individual items related to securities are significantly positive over time. Second, we perform a regression on returns to test for value relevance and find that aggregated DSF and individual items related to currency translation differences and cash flow hedges are value relevant in explaining returns.

Tjänligt vatten i kranen - Membranteknik gör det möjligt : En utredning av pilotförsök i Glemmingebro

Nanofiltration is a proper way of preparation of drinking water. The process has a lot in common with reverse osmosis where a semipermeable membrane is used to separate a pure water flow from the remaining water. A pilot plant was used to ensure that nanofiltration is a suitable technology for a specific waterworks station in Glemmingebro, Ystad. The purpose was also to find out if a pH-adjustment is needed for feed water in a possible full scale plant.  In this case nanofiltration is used mainly to remove sulphate and calcium since the raw water contains concentrations of these substances which exceed the limits for potable water. It is important to receive a high recovery (RC), otherwise the deliviery of water won?t be high enough.

Tillväxt i medelstora företag: En problem- och åtgärdsanalys för tillväxt hos Sveriges "bortglömda" företag

Many sources point to the same conclusion; throughout the history the research sphere, mass media, governmental industry policies and public life in common have not paid the same attention to medium-sized companies as to small, new or large companies in Sweden. Yet, there are some researchers claiming the need for the medium-sized companies to grow, becoming tomorrow?s Swedish new large companies. Hence, the need for understanding the specific growth conditions of the medium-sized companies are definitely clear. This study aims firstly to identify whether there are specific requirements and obstacles for growth in connection to being a medium-sized company.

Om den ofeministiska jämställdheten och den ojämställda feminismen: en diskursteoretisk analys av en feminismskritisk jämställdhetsrörelse verksam på nätet

This essay analyses text written by a gender equality movement critical of feminism. Themovement is active on the Internet and through this essay I would like to show the tensions in contemporary political debates on gender equality and feminism. 350 blogposts have been deconstructed through discourse theoretical method. In the analyses I have shown the discursive struggle that is going on within the movement in giving meaning to concepts as knowledge, society, gender, politics, feminism and gender equality. The movement is using the technical potential in blogs and common Internet forums tocreate a common political we.

Ramar och reflektion : Om designprocessen som didaktiskt alternativ

By studying literature concerning design, didactics and reflection, and complementing those explorations with interviews with experienced design educators, this thesis challenges the idea of aesthetic media education being purely aesthetic in its characteristics. Drawing from their own experiences as a media aesthetics educator and an industrial designer, the two authors argue that the work flow used within most fields of design, commonly known as the design process, might provide a suitable didactic alternative to a field of education lacking relevant methodology. The literature study offers a better understanding of the design process and how it may be defined and viewed within an educational context. The interviews provide a more practical insight into the world of design education. The result shows that the design process as a didactical method theoretically offers both elements of critical thinking as well as direction and frames for students lacking aesthetic and artistic experience.

Centrala logistiska faktorer i en förädlingskedja för massproduktion av träpellets : Fallstudie på Kopparfors Pelletsfabrik

This examination work aims to describe how a supply chain around the biggest pellets factory in Sweden will be configured in a logistic perspective. The plant and associated infrastructure are in the building phase and will have production start on the 2 November 2009. The key question that is set in this examination work is to recognize the logistic processes which are essential for an effective flow of materials and information that link the source of supply with the ultimate customer. In order to get the answer, a flowcharting of these supply chain processes is required for understanding the pipeline activities such as input and storage of raw material, the production system and the output of pellets to the customers. The basis for this supply chain map is a model-based representation of these logistic processes and activities that are involved around the pellets factory.

Jämförelse av frånluftsvärmepumpar

In order to reach the environmental targets, set up by the EU, there are many measures taken to make Sweden more energy efficient. In the housing and real estate sector, an installation of an exhaust air heat pump that reuses the heat in the exhaust air in order to lower the amount of acquired energy, is an example of such an action. The recovered energy can then be used for heating of radiators and tap water. This report aims to evaluate and compare three different systems using exhaust air heat pumps regarding COP, degree of coverage and cost savings. This study was delimited to only account for apartment buildings.The theory chapter describes the different conditions and factors that affect a building?s energy balance.
