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.

Årstidsdynamik för kvicksilver i ett sövattensediment :

The limit for mercury in fish, set by health authorities, is exceeded in about half of the lakes in Sweden. Methyl mercury (MeHg) is the most toxic form of mercury and accumulates in fish. Therefore transformation of inorganic mercury (Hg) to methylmercury (MeHg) is an important process that we need to understand in order to possibly counteract the negative effects of mercury in the environment. The seasonal dynamics of mercury biogeochemistry is likely of great importance for the accumulation of MeHg in the aquatic food web. In thesis the chemical speciation and transformations of Hg and MeHg in bottom waters and sediments is followed in Ängessjön, a small lake located on the east coast in the middle of Sweden. The lake is not directly affected by any industrial pollution and concentrations of Hg in the sediment reflect the atmospheric deposition in this area, as well as processes taking place along the hydrological pathways from soil to lake. Samples from sediment, bottom- and streamwater were collected in average every second month during the period Feb.

Små brottsoffer : En analys om barns bemästringstrategier av våld

The purpose of this paper is to give a view of how violence and victims has been portrayed in novels. I have chosen 6 books where the main character is a child who has been exposed to physical, mental and/or sexual violence. I have asked questions to the book and I have tried to find patterns in the child's strategy to cope with violence and how the violence is described. I have also written two chapters about earlier studies of this field and theoretical standpoints. The main perspective I present is the salutogenese perspective and how people create meaningfulness in their lives.The children in the books have different ways to handle their situations.

Nitrogen flow in Scania : substance flow analysis on a regional level

In this thesis, the flows of reactive nitrogen (Nr) in Scania were investigated and quantified. The thesis was also intended to form a basis for comparison between the urban nitrogen flow and other flows of nitrogen within Scania. The management of nitrogen in society has disturbed the natural nitrogen cycle. This is linked to a series of environmental problems such as eutrophication, acidification, global warming and smog. The method used was Substance Flow Analysis (SFA) for Nr. For calculation and flow charts Scania was divided into three subsystems; air, water and society.

Bakom och genom ordet: Selma Lagerlöf i brev och historieskrivning

The object of this study has been to establish how language is used to present and establish a person?s identity. The studied language usage is that of renowned author Selma Lagerlöf and the language studied is that of her personal correspondence. This language picture is placed alongside the public depiction of her and a comparison of sorts is made. The chosen method has been to study Lagerlöf?sprivate correspondence and to compare her language markers in those to the literature history?s picture of her.

Fördjupad miljöriskbedömning av förorenade markekologiska system. : Integrering av kemisk, toxikologisk och ekologisk information.

AbstractThe research project Liberation, supported by the European Commission under the Environment and Sustainable Development Programme (Fifth RTD Framework Programme) aimed at developing a decision support system for ecological risk assessment of contaminated sites has proposed a tiered system including the triad method. This method integrates contaminant chemistry and bioavailability analyses with observed ecotoxicological effects in soil and groundwater. In this study the triad method was used to perform a risk characterization of a former surface treatment and metal industry, now used for the student union buildings of the Mälardalen University in Eskilstuna, Sweden. On the site, high concentrations of copper, zinc and nickel have been detected in the soil in a preliminary investigation of contaminant levels with XRF. For performing the risk assessment of the site according to the triad method, contaminant bioavailability, soil metal concentrations and soil toxicity were determined and an ecological assessment was carried out on four selected soil samples (one reference soil and three samples with low (B), medium (C) and high (D) contaminant levels). Contaminant bioavailability was measured through leaching (ISO TC 190/S7) and biouptake tests (DGT).

Upphovsrätten incitament eller slutstation? En ideologikritisk analys av The Association of American Publishers och Authors Guilds syn på upphovsrätt.

The aim of the following thesis is to examine if the ideology behind the copyright laws of today poses a threat to creativity and the cultural heritage. The organizations Association of American Publishers and Authors Guild are subject to an ideology- analysis which seeks to examine their ideological views on copyright and the possible threat to creativity such a view brings. The conflict between the two organizations and Google Book Search is used as a context where the ideology is being brought to light. Stanford Law School professor, Lawrence Lessigs work is used as theory and an alternative to the examined view on copyright. The result suggests that the organizations see copyright as the only effective incentive to creation and therefore they think stronger intellectual property laws are needed.

EU och informationsfriheten. En idé- och ideologianalys av informationsfriheten i EU:s datalagringsdirektiv 2006/24/EG.

This master?s thesis is about freedom of information ideas in the European Union data retention directive, 2006/24/EC. The directive means that data about electronic communications services will be retentioned. The aim of the thesis is to examine what ideas related to freedom of information that appear in the directive and how these ideas belong to the ideology of freedom of information that is common within the library community and to the juridical restrictions. In the light of surveillance tendencies that have occurred over the last years, the most well-known is probably the USA Patriot Act, it is interesting to study how freedom of information ideas appears when surveillance is legislated.

EMU som ett exempel på konstitutionell självbindning

This essay presents an alternative approach to the predominant democratic analysis of the European Monetary Union. As the Treaties stipulate the political conduct within Monetary Union and put certain restrictions on the European politicians they are to some extent constitutional in their character. Essential for constitutional theory is the concept of precommitment; according to which a decision is made in t1 purposing to obstruct certain actions in t2. In light of this the aim of this essay is to investigate whether or not delegating monetary responsibility to the ECB can be seen as an example of constitutional precommitment and if so, if this constitutional perspective can add something to the predominant democratic analysis of the EMU. According to the author the EMU is by and large a form of precommitment as the leading politicians in Europe figuratively have tied their hands from intervening in the common monetary policy.

Miljösystemanalys av alternativa avloppssystem i ett urbant område ?Svartvattensystem : Skogaberg ? Ett pilotprojekt i Göteborg

Starting point to this Paper is the idea and wish to adapt the society and its different activities to a recycle society. A building area in Göteborg is planned and investigated for such adaptation. In the district named Skogaberg, about 130 households totally are planned from what 20 are blocks of flats. The idea with this project is to constitute an alternative sewage system, a Blackwater system, were the fractions of most nutrients and least pollution are separated, taken care of and utilised. The aim is to get a market and use the nutrients of the organic waste from the household in agriculture use.

Renskötselrätten : som rättslig konstruktion

This master thesis concerns the relation between law and the theory of the conceptual metaphor which has developed within cognitive linguistics. Although its main focus is abstract thinking, it also covers a wide range of aspects within cognitive linguistics, such as the prototype theory and radial categories. In order to address this relation, three questions will be dealt with. Firstly, does the theory of the conceptual metaphor have relevance to interpretation of legal rules and contracts? Secondly, can the same theory explain why a legal rule or a contractual term has been interpreted outside of its most given area of application? Thirdly, when an interpretation is not predictable from a legal viewpoint, can such an explanation answer to that fact? Answering the first question will require a descriptive analysis of the conceptual metaphor and cognitive linguistics.

Mobilt arbetssätt inom sjukvården och patientens personliga integritet : Klarar patientens integritet att journalen görs tillgänglig för sjukvården mobilt?

In the light of new technology health care is now given the opportunity to form a more mobile way of working that would bring about potential gains in terms of efficiency and quality. On the other hand, a more mobile health care also requires a more generous handling of personal information, something that may raise issues in terms of privacy. This study shows that the privacy of the patient requires two things: (i) that the personal information of the patient is handled in a way that generates her an overall positive expected utility and that (ii) the negative expected utility that each risk of an information leakage causes is offset by the expected utility it also makes possible. The first requirement (i) is shown, in comparison with today?s way of working, to be met due to the potential gains in efficiency and quality in combination with no increase in the probability of informational leakage or negative effects of such a leakage. The second requirement (ii) was also considered met since no separate risks of information leakage could be identified that was not offset by the gains it made possible in terms of expected utility..

Ren hud : En litteraturstudie om hur omvårdnadsåtgärden hudförberedelse har betydelse för postoperativa sårinfektioner

Postoperative site infections are the second most common health care associated infection in Sweden. Surgical procedures can lead to postoperative site infection causing great suffer for the patient and an extended care time with an increased cost as a result. In preparation for surgery, it is important that the skin is well prepared with antiseptics to decrease the risk of postoperative site infection. The purpose with this study was to shed light upon the skin preparation before surgery and its significance to postoperative site infection. Ten scientific articles have been scrutinized and compiled and two themes have been identified ? the preoperative and the intraoperative skin preparation.

Television eller ?tell-lie-vision?* : En kvalitativ studie om barns tevekonsumering och deras egna tankar omkring den.

This examination intends to find out what thoughts children in around 12 years of age thinks about their own television consumption. To examine this, the questions in issue is: ?What does the children watch on television?? ?Why do they watch the programs they do?? ?How do the children speak about their own consumption?? ?What does the children learn from TV?? ?Are the children concious of the impressions they take from TV?? ?Do they speak critical about TV?? ?Is there anything indicating on some kind of influence from the childrens television consumption?? .To answer these questions I have chose to hold qualitative interviews, to let the children?s own thoughts be the foundation of the examination. The theories in this examine are that the person who does the consumption from different forms of television takes the information personally out of her own reality. Meaning that the person watching is the judge of how she applies the information to herself.

Heliga sopor : skärvstenshögen utifrån ett polynesiskt perspektiv

In Scandinavia the general idea of the Bronze Age society is that it was organised as chiefdoms. The model for what they looked like is taken from the anthropological studies of the Polynesian chiefdoms. The aim of my study is to investigate a Scandinavian Bronze Age feature, known as cairns mainly containing fire-cracked stone. This is compared with how people in different Polynesian chiefdoms, looked at similar remain. This is done to get a background for new ways of interpretation of such remains.
