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.
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.
Faktorförsökbaserad diskret händelsestyrd simulering av trafikflöden under långsiktiga prognoser: En fallstudie vid Göteborgs Hamn
Världshandeln växer kraftigt och det vanligaste sättet atttransportera gods mellan landsgränser är genom sjöfart. I takt med attvärldshandeln växer, ökar också storleken på fartygen. Detta innebär att enstörre mängd gods anländer samtidigt när ett fartyg förtöjer vid en hamn. Föratt hantera denna ökade mängd gods måste godsnav och hamnar ständigt utvecklaoch effektivisera verksamheten. Detta innebär att långsiktiga prognoser ochplaner måste utvecklas för hur större fartyg skall kunna hanteras.
Reglering av matarsystem vid höghastighetskapning
Today small metal parts are mass-produced as for example rollers in cylinder bearings. At high velocity cutting the metal is cut with a great force in a scissor-like device. Both precision and repeatability is important to be able to guarantee good quality, but from an economical point of view it is also important to keep a great manufacturing capacity. The part of the process that is most time consuming is when the metal bar, that is about to be cut, is fed to the right position. Therefore it is interesting to examine if the time used for positioning can be reduced.
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.

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.
Improvisation i fokus : övning av improvisation i jazzmusik
Diskussionsforumet Flashback Forum har med sin slogan ?Yttrandefrihet på riktigt!? etablerat sig som det forum på Internet där kontroversiella åsikter och provocerande material får fritt spelrum. Detta gör forumet till en tacksam forskningskontext när det gäller föreställningar om något så allmängiltigt som välfärdsverksamhet. Studiens syfte är att synliggöra de föreställningar om socialtjänsten och socialarbetare som finns på Flashback Forum, bilda en diskurs av dessa och sedan jämföra diskursen med andra diskurser kring samma fenomen. Flashback Forumdiskursen genomsyras av fyra teman; Misstro mot socialtjänsten och socialarbetare, Socialtjänsten och socialarbetares verksamhet, Socialtjänsten, socialarbetare och kön samt Tilltro till socialtjänsten och socialarbetare.
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.
Golvskyltens oanade effekter - En studie om golvskyltens outforskade effekter
Floor signs in stores have become a more common phenomenon during past years. The problem is that the knowledge about these signs is limited and the actual effects are unknown. This lack of knowledge can have a negative impact on store performance and marketing efforts. The purpose of this paper is to examine the effects of floor signs on consumer attitude and behaviour. The study was conducted in two grocery stores, where the movement pattern of 39 501 customers was recorded over a four week period.
Juniorfinansiering i fastighetsbranschen? Fokus kring Mezzanine
Real estate financing is one of the key figures for financial success and fundamental to asuccessful business. Funding will come in several different ways, from existing cashflows andassets to new capital requirements which are aimed at different markets.These markets are constantly changing and since the recent financial crisis, there have beenadjustments and austerity measures which led to that the banks have become more restrictive intheir lending.The real estate industry is characterized by both long-term and short-term thinking that ischaracterized by a solid continuity. Our thesis discuss how the demand is in the real estatebusiness and how mature the Swedish market is for junior financingwith focus aroundmezzanine debt and where are we headed in the near future.We've reached out to the key players in the industry on both the buy and sell side of real estatefinancing but also people between lenders and borrowers that handles transaction advice. Tohave been able to implement the analysisa survey and simulation of an investment calculationwas created. This questionnaire was answered by many real estate companies with senior peoplethat had operational positionsmost associated with corporate commitments.
Simulering av energieffektiviserande åtgärder för små- och flerbostadshus : Möjligheter för JM:s hustyper att uppnå passivhuskonceptet vid nybyggnation
The purpose of this project was to evaluate how energy efficiently some of JM?s residential buildings can become in standard production. What kind of measures are needed to achieve the level of energy demand that is included in BBR12 (Boverkets Byggregler)? What measures are needed for achieving a lower demand so that the buildings could be classified as passive houses? The investigation has included a single family house and two different types of apartment blocks.The simulation programs Enorm and VIP+ have been used to calculate the energy demand of the buildings. The results from the programs have been compared with the measured energy demand for the three buildings.
