Textilindustrins avloppsvatten och avloppsslam ur ett miljöperspektiv : Underlag för internationella riktlinjer inom projektet Sweden Textile Water Initiative
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.
Affekter för hållbarhet
Syftet med denna studie var att undersöka vilka samband det finns mellan
värderingar, föreställningar och normer kring miljön till agerande för
ekologisk hållbarhet i det vardagliga livet. Vår hypotes var att det finns
samband mellan affekter kring miljöns framtid och agerande till hållbar
utveckling. För att söka svar på syftet och bekräfta hypotesen har enkäter med
frågor gällande individens värderingar, föreställningar och normer om miljön
samt frågor om miljömässigt agerande skickats ut via e-post till 119 deltagare
i åldern 23-65 år. Svarsfrekvensen var på 59 procent. Resultatet visade att det
fanns ett flertal starka samband mellan miljömässiga värderingar,
föreställningar och normer till individens agerande och hypotesen om att det
fanns samband mellan affekter och agerande för hållbar utveckling verifierades.
RELATIONSMARKNADSFÖRING : Att skapa relationer över Internet
Schizophrenia can cause symptoms such as auditory hallucinations, delusions, emotional blunting, apathy and lack of motivation. These result in a diminished ability to participate in daily activities and bring the client group into the domain of occupational therapists. The purpose of this literature review is to compile the latest findings in occupational therapy interventions for individuals with schizophrenia. Furthermore guidance regarding the utility of the interventions will be given based on the author?s assessment of the evidence in the 22 articles included.
Feromoninnehållande substansers effekt på hjärtfrekvensen hos kvigor i östrus och diöstrus :
With increased milkproduction in our dairy cattle, comes a risk for a reduced fertility. Studies performed on animals and humans have shown that it is possible to manipulate the oestrous cycle through exposure to pheromones. This means that pheromones could potentionally be used to make reproduction more efficient. To evaluate the bioactivity of the substances in question, there is need for a bioassay. In insects, pheromones can induce a changed cardiac activity.
Det ansiktslösa ägandet, en pådrivare av utdelningar?: En studie i hur det institutionella ägandet påverkar svenska börsbolags aktieutdelningar
This paper investigates the relationship between dividends and institutional and foreign ownership in Swedish firms. We use a dataset which covers the Swedish stock market over the period 1999-2009. The institutional ownership is defined as mutual funds, pension funds and insurance companies and these are analysed separately. The study confirms the expected positive relationship between the level of institutional investors in a firm and the size of dividends. We also confirm? the expected negative relationship between foreign investors and the size of dividends paid by Swedish firms.
Reglering av laborationsprocess med Matlab/Simulink
AbstractIn the fall of 2003 a project was started in the Swedish building sector that is called BASTA (the building sectors’ termination of especially harmful substances). The project is operated by the building companies NCC, Skanska, PEAB and JM, the Swedish Building Industry and the Swedish Environmental Institute IVL. The purpose of the project is to create a common environmental assessment system for the entire building industry and with the help of this system phase out the use of especially harmful properties from building products.In a large sense BASTA works like this; On the BASTA web site there is a database, to which a supplier can register the company and the company’s products. Only those products with a substance content that fulfil the demands of the BASTA system, is to be registered. As it is the supplier himself that carries out the registration of the company and the company’s products to the system, the BASTA-organisation annually controls that the companies that are registered in the database, fulfils BASTA’s demands.Since NCC is one of the companies that operates BASTA, BASTA is probably going to be the environmental assessment system that is recommended for the company in the future.

ABC-kalylering i grossistföretag -modelldesign och effekter
Background: A large number of companies works as a link between manufacturers and final users. These companies buys and stores goods to be able to deliver when a need comes up later in the chain. The storage could have a negative effect on profitability and therefore places great demands on the management control systems. ABC as a method has been used with some success in manufacturing for over ten years. In wholesale companies the method is not frequently used.
Hållbar Utveckling 2010 : Hur uppfattar lärare begreppet idag?
This work is a study of subject teachers in social studies and science understand the concept of sustainable development. The work uses a qualitative and a quantitative approach. Teachers in various schools and stages have been answering questions about how they perceive sustainability, how they implement it in teaching and if they feel that school is important for the future of sustainable development at large.The theoretical background is based on environmental ethics as well as the different meanings and definitions of the concept of sustainable development. These theories and definitions are coupled with the empirical results.The study concludes that all teachers throughout the study perceive the concept of sustainable development as something ecological, something that has to do with nature. A few teachers also state economic and social dimensions.Questions about how the teachers in the study implement the concept in their teaching can be seen as three different approaches.
Hållbar utveckling och ekologisk modernisering i partipolitiken : En jämförande studie av Socialdemokraternas och Moderaternas miljöpolicys
Hållbar utveckling som begrepp används frekvent i dagens samhälle och är också det övergripande målet för svensk nationell strategi. Syftet med den här uppsatsen är att undersöka i vilken utsträckning hållbar utveckling och/eller ekologisk modernisering beskriver miljöpolicyn hos de två största politiska partierna i Sverige. Dessa två partier, Socialdemokraterna och Moderaterna, tillhör varsitt partipolitiskt block med olika ideologier.Resultaten i uppsatsen visar att det finns väsentliga skillnader mellan de båda partiernas miljöpolicys som är grundade i olika politiska ideologier. Socialdemokraterna har sina rötter i frågor som demokrati, social rättvisa och välfärdsfrågor, och deras miljöpolicy överensstämmer till stor del med hållbar utveckling. Moderaterna utgår från liberalkonservativa idéer med utgångspunkt i individualism och marknadsbaserade ekonomier och deras miljöpolicy harmoniserar överlag med ekologisk modernisering.
Ekosystemtjänster : En studie av kunskapsläge, hinder och strategier inom kommunal förvaltning
?Ecosystem services are the ecosystems direct and indirect contributions of ecosystems to human well-being.? In order to reach the generation target and the environmental objectives it is important to increase the awareness of biodiversity and ecosystem services and it?s importance to human welfare and simultaneously highlighting the value of ecosystem services. The value of ecosystem services should be integrated into economic standpoints, political considerations and other decisions in the society. In today?s society there is a problem concerning that the value of ecosystem services are not considered in economic terms, which can result in solutions that are unfavorable for our welfare (Ministry of Environment, 2012).
IgG mediated suppression of immunological memory
Apart from recognizing and neutralizing threats, antibodies also have the ability to regulate immune responses against their specific antigen. IgG administered together with erythrocytes is well known to induce >99% suppression. This has been used to prevent haemolytic disease in new-borns since the 1960's, but the mechanism behind it is still not completely understood. The effect on the primary response is well established, but its influence on induction of immunological memory is still heavily debated. In this study adoptive cell transfer of splenocytes to irradiated mice was used to survey the effect IgG has on induction of immunological memory without disturbance from the primary IgG response.
PLASTHANTERINGEN I SVERIGE En kvalitativ studie om storstadskommunernas plasthantering utifr?n EU:s Plastdirektiv (EU) 2019/904
The aim of this essay is to examine the handling of plastic waste on a local level in the three
municipalities of Gothenburg, Malm? and Stockholm. This is achieved with the help of
guidance within the theory of Multi-level Governance. By applying the EU directive
2019/904, about disposable plastic, and examining the global plastic problem, the efforts to
promote sustainable use, and recycling of plastic, is analyzed. The method involves a
qualitative content analysis, where the 2022 waste plans of the three municipalities, ?Sveriges
handlingsplan f?r plast? by the Government Office, and the 2019/904 EU directive constitutes
the base of the study.
