Vattenhantering och reglering för textilproducenter i Turkiet

Vatten är en av jordens livsviktiga resurser, en resurs som hela tiden minskar. I delar av världen råder akut vattenbrist och ofta återfinns industrier med hög vattenanvändning i områden med begränsad vattentillgång. En av dessa industrier är textilindustrin. Vid textil beredning är vattenförbrukningen mycket hög och avloppsvattnet är ofta mycket förorenat. Vattenfrågorna inom textil produktion har fram till idag inte uppmärksammats i lika stor grad som arbetsrätts- och kemikaliefrågorna.

Regeringens miljösatsningar och deras förhållande till en hållbar livsstil hos det svenska folket : En studie av biståndssatsningars påverkan på hållbar livsstil i givarlandet

Swedish government aid is divided into three main themes: democracy and human rights, the environment and climate, and gender equality and women's role in development. These three themes in aid are considered by the government to be vital in order to fight poverty and create fair and sustainable development. This study will examine two of the four focus areas designated under the theme of "environment and climate". The study observes the relationship between projects in energy and water and how it promotes a sustainable lifestyle. A survey on environmental habits will be conducted.

Att öka mottagligheten för branded content genom hyper-personalisering : En användarstudie mot målgruppen för digitala tidskrifter inom populärkultur.

I denna studie utreder jag om hur branded content mottas avmålgruppen för digitala tidskrifter inom populärkultur genom enframträdande teknik in webb-personalisering, hyper-personalisering.Målgruppen för denna studie är unga opinionsbildare som konsumerarinnehåll från digitala tidskrifter som exempelvis Nöjesguiden. Brandedcontent, sponsrat innehåll, är innehåll som skapas för att ett varumärkeskall förknippas med en kreatörs målgrupp. Alltså kan ett varumärke beNöjesguiden skapa redaktionellt innehåll som bör tilltala målgruppen förden digitala tidskriften, och på så sätt skall målgruppen få en nyuppfattning eller fortsatt positiv syn på varumärket. Hyperpersonaliseringär en teknik som appliceras för att kunna rikta innehåll,tjänster eller produkter mot individer inom en målgrupp med träffsäkerrelevans. Tekniken kräver en stor mängd insamlad social data och det blirdärför intressant att föra en diskussion kring hur målgruppen reagerar påatt man kan genomföra en sådan enorm insamling av data.

Marmorering i nötkött : påverkan av ras och foderintensitet

The water tower in Uppsala city forest was built in the late 1950's in what is now a nature reserve. The unique place was supposed to be visited by people, which is currently not the situation. This bachelor thesis aimed to perform an analysis and make a design proposal for the environment surrounding the water tower. The analysis was performed using the methodology previously described by architect Arne Branzell. The methodology focuses on how a space is perceived by a person moving through it.

Fosforförluster från lantbruket och dess bidrag till övergödning av sjöar och vattendrag i Växjö kommun

The possibility for plants to utilize phosphorus in soil is a prerequisite for conducting agricultural production, both small scale and professional. Spreading of phosphorus fertilizers and manure is therefore seen as a necessity in today's agriculture in order to achieve high yield. Manure management, livestock farming and manure storage could contribute to the eutrophication of lakes and rivers. For instance, when the ground becomes saturated, phosphorus leakage could be seen in surface runoff or in point sources resulting from inadequate manure storage management.In the municipality of Växjö there is still many bodies of water that do not reach the Swedish environmental water quality standard of "good ecological status". This thesis has therefore analyzed the manure management and storage on agricultural farms which may have contributed to eutrophication in the municipality.The method for this thesis was a literature study, a questionnaire survey with 820 receivers and a summary of issued inspection reports from 2013.The results highlight the ways in which agriculture may have contributed to the eutrophication of lakes and streams in the municipality of Växjö.

Konstruktion av en fotobioreaktor för odling av alger : ett småskaligt försök

The prevailing food and energy crisis of the world, due to the declining reserves of fossil energy and a never ending rise of consumption, forces us to look into new fields to supply our energy demand. The boom of bio energy is criticized, as food crops are used to provide biodiesel and ethanol and the volumes are ridiculously small to supply world demand. Algae are one of the world?s oldest life forms and exist in many different phyla, providing a great variety to choose from, for different purposes. Cultivating microalgae offer a way to produce energy at great volumes without competing with food production and at the same time the algae offer a way to use our expensive nutrients in a more efficient way, besides this the algae are carbon dioxide neutral since their carbon source can be supplied by the atmosphere and the additional energy required can be supplied by algal oil or other renewable sources.

Miljöanpsassad metod för hjultvätt

In order to avoid harmful substances ending up at the municipal sewage treatment plants, it is important to purify the wastewater at the source. One such source is the wheel washers available in many tire garages which are used to wash the wheels on our vehicles when we change between summer and winter tires. It is important to wash the wheels before storage, to extend the tires lifetime. The purpose of this study is to find a green innovative solution for reduction of emissions of heavy metals at the source, so that the sludge from the sewage treatment plants can be used as fertilizer. The target is to find a wheel wash method which leads to compliance with the guidelines for car washers, and that also provides a better washing result than with the existing method.

Strukturkalkningens möjlighet att hindra fosforutlakning : en litteraturstudie

The purpose of this essay is to find out if liming with Ca(OH2) and CaO can reduce leachingof phosphorus from agricultural land and the problem with eutrophication. This purpose alsoincludes getting knowledge about how to make the phosphorus retained in the soil and beaccessible for the plants. This essay is supposed to show if more research is needed in thissubject. There has not been much research about this subject and therefore the amount ofmaterial to study is limited in this literature review. The research reports that have beenstudied have similar results.

Karaktärisering, utvärdering och avsättning av Stena Metalls magnetiska fines

With a growing population on earth the amount of end-of-life vehicles (ELVs) and other scrap steel increases. The European Directive 2000/53/CE? requires a minimum of 95 % reuse and recovery and 85 % re-use and recycling no later than 1 January 2015, for end-of life vehicles. This imposes a need for more efficient recycling and recovery. Despite this shredder residue (SR) is commonly land filled.This report investigated the magnetic fines residue generated at Stena Metall shredder facility in Halmstad, Sweden.

Rimbo våtmark : en förstudie på förväntad kväveavskiljning och lämplig växtlighet

This study was made as a part of a feasibility study on a polishing wetland at Rimbo wastewater plant (wwp) in Norrtälje municipality. The wwp had to decrease the nitrogen discharge to reach the limit 15 mg tot-N/l. The nitrogen in the outlet was mainly in the form of nitrate, hence the wetland mainly ought to support denitrification. The proposed area for the wetland was situated right next to the wwp and was already in the municipalitys posession. One aim of this study was to examine what spieces of plants needed to achieve highest possible denitrification.

Impressions of reality

Impression of reality deals with the subject of wearing a mask. It is an exploration of the idea that we are all playing different roles, on a stage in front of an audience. The aim was to work conceptually with text, photo and video as a way of exploring a subject. The goal was to create and edit the material so it would be interesting for the visitor at the graduation exhibition. The content was created through experiments based on questions such as the following examples; What is a mask? How can content control form? What is originality? The process resulted in a publication and a video installation with the ambition of highlighting the idea of the world as a theatrical construction.

Är det möjligt att använda SCR-rening av rökgaserna vid inblandning av avfall i biobränslet?

Waste appears to be a low-cost fuel compared to biofuel. This Masters thesis was conducted for Vattenfall Utveckling AB and deals with how waste in the fuel affects the performance of a SCR-catalyst. Different mechanisms of deactivation were surveyed, focusing on the poisoning mechanism. A literature study was carried out, which was used as a reference when analysing the results.Small samples (9x2x2 cm, 64 pieces) cut out from a full-scale unused honeycomb catalyst were exposed up to 1500h in two different combustion plants, Johannes in Gävle (co-combustion) and Högdalen in Stockholm (waste-combustion). The activity was measured mainly at 300°C but also at 250, 350, 375 and 400°C.

Jämförelse mellan sojaböna och åkerböna som proteinfoder till växande grisar

The soybean can be used in multiple ways, and its high oil content makes it suitable for extraction. Soy bean meal, a by-product of the oil extraction, is a good source of protein with a high feeding value, and is therefore used in a number of different animal feeds. Further, soy bean meal has a low production price, which is one of the reasons for the extensive export of the product. There is a great demand for vegetable-based proteins, especially in the organic production where synthetic amino acids are banned. However, the current production of soy beans is not environmentally sound and that combined with the long transport distances amplifies the need of finding a locally produced protein source.

Våldsamma, sexistiska och rasistiska tv-spel på folkbiblioteket ? en undersökning om bibliotekariers syn på och hantering av kontroversiella tv-spel

The aim of this thesis is to study the views of public librarians on the subject of controversial video games and how they work with them at the library. The purpose of the study is to answer these questions: What content is controversial in video games according to the librarians? How do the librarians handle the controversial games at the library? Does it exist a conflict between the users and the librarians about the controversial video games? Is it possible to see any underlying reasons or tendencies in the librarians answers? Five qualitative interviews were performed to answer these questions and the collected data was analyzed using the terms, value rationality and instrumental rationality which were collected from a theory by Geir Vestheim. The results showed that the librarians see violence, sexism and racism as controversial content in video games. They handle the games at the library by limiting the access for children with age limits and by not buying the most controversial games in some cases.
