This study includes a life cycle assessment, LCA, on an ecological produced cotton shirt for the company Reflective Circle, which designs ethical and ecological clothes.Initially were cotton farming and textile production studied to gather basic knowledge about the processes. Since this shirt is being ecological produced in the whole production chain, we studied what an ecological production means, but also how a conventional production works. When this was done we could start to discuss the differences and similarities between the production of the shirt and general conventional production.When the LCA was first initiated, the main focus was on the green house gas emissions from the manure at the cultivation. Thereafter the process steps such as picking, ginning, carding, spinning, weaving and sewing were being studied. The picking is done by hand, but the rest of the processes are handed by machines which consumes energy.

The aim of this essay was to study the nitrogen flow in two willowplantations, at different locations in the south of Sweden, that wereirrigated with sewage. The study was also performed to compare thedifferences in nitrogen flows between two years, 1998 and 1999. The studywas made in three parts. First, the denitrification activity was measuredusing the acetylen inhibition method. Second the nitrogen flow, as well asthe water- and heat flows, were modeled through the SOIL-SOILN-modelThird; the nitrogen flow was calculated to compare with the results fromthe model.The results from the measurements were then compared with the resultsfrom the SOILN-simulations to detect differences in the denitrificationrate.

AbstractThis degree thesis was made in cooperation with Chematur Engineering in Karlskoga.Many of the environmental issues of today are a result of the motor traffic. Consumption of fossil fuels harms our environmental through formation of carbon dioxide and other greenhouse gases. To get under control with our environmental issues it?s important to find substitutes for oil that are both cheap and environmentally friendly. Ethanol has a long history as a motor fuel and is both enviromentally friendly has a high efficiency.According to the EU commissions directives for motor fuels, 5, 75 % of all the fuels in Sweden should be renewable in 2010.

I det här projektet har uppgiften varit att rena vattnet i Aqua Interiör i Laholms egen tillverkade vattenmöbel med hjälp av uv-ljus. Dessa möbler hyr de ut till kunder för att kunna få ett lagom kallt vatten med eller utan kolsyra. Vattenmöblerna är direkt kopplade till det befintliga vattensystemet. Ett problem som de tidigare haft är att de inte kunnat ha sina möbler på sjukhus eftersom möblens beskaffenhet medför en ökad bakteriehalt i vattnet.Denna bakteriehalt kommer dock inte upp till den gräns som livsmedelverkets satt som icke tjänligt. På sjukhus finns ett högre krav på vattnets kvalité där inga anmärkningar får finnas på vattnet.

Transportation constitutes a large part of the forest industry's raw material costs. Transport also contributes a significant proportion of the carbon dioxide emissions. In order to reduce both the cost and environmental impact different types of decision support are required. These, in turn, require extensive information about the road network and correct information on road path selection and transport distances. In the development of national road data base for forestry (SNVDB) a road selection application has been included.

The world we live in becomes more globalized as a result of new communication media. Communication occurs over greater distances which leads to increased travel. In the report AR5, by IPCC, it is showed that the human impact of climate change is clear and that something has to be done. Therefore its very important to change the human impact. A part of it is to change the way we travel within the service which leads to the purpose of the thesis.

That air pollutants of different kind has impact on our climate can hardly haveavoided anyone during the past years environment explosion in the media. But howis it actually with the reverse, i. e. the climate's impact on air pollutants? The aimwith our degree thesis is to try to find out if different weather factors, statisticallyseen, promotes atmospheric pollutants and particles in the air and vice versa.We got access to data on air pollutants and weather factors that was registeredduring year 2007 at Femmanhusets air pollutant and weather station in Gothenburg.In order to do a statistical investigation of these data, and to be able to analyze if itoccurs relations of various kind, we used the statistics program SPSS.

Runt om i världen utförs miljontals kirurgiska ingrepp varje år, sedan 1840-talet har utveckling skett för att reducera antalet vårdrelaterade infektioner. Postoperativa sårinfektioner är den vanligaste typen av vårdrelaterad infektion och utgör ett stort lidande hos patienten. Som operationssjuksköterska är det viktigt att ha kunskaper om riskfaktorer för postoperativa sårinfektioner för att kunna sätta in adekvata omvårdnadsinsatser. Mot denna bakgrund var syftet med denna litteraturstudie att belysa riskfaktorer för postoperativa infektioner som finns i operationssalen med frågeställning hur operationssjuksköterskan kan påverka förekomsten av postoperativa sårinfektioner. Metoden som används är litteraturstudie där databaserna Cochrane och Pubmed har genomsökts.

I Lovisagruvan i Bergslagen bryts zink och bly, gruvvattnet (med pH 7-8) är förorenat av framförallt dessa metaller (577 ppb Zn, 341 ppb Pb). Reningen i de sedimentationsbassänger som finns på området fungerar inte tillräckligt bra. I denna studie användes sand från Stråssa (s.k. Stråssamull) som filtermaterial för att rena vattnet. Två olika sorters filtermassor testades, obehandlad Stråssamull (SM) och järnoxyhydroxidbelagd Stråssamull (JSM).

The demand for food, feed, fibre and fuel has increased in Uganda over the past 50 years due to population growth. Recurring extreme climate events such as drought and flooding, in combination with large-scale land degradation, have led to declining crop yields. Lack of equipment, money and socio-economic issues has contributed to low yields. However, the soils in Uganda have the potential to produce much higher yields than they do today. This study, which was carried out in April-June 2013 in Kkingo District, south-east Uganda, examined the effects of agroforestry on yield of cooking bananas in small-holder farming systems. Six farms practising agroforestry and six farms with no agroforestry, which were chosen in cooperation with the NGO Vi Agroforestry, were compared.

The aim of this master thesis is to gain greater knowledge of interpersonal communication. This study explores on one hand how interpersonal communication can be used as an important part of reference work in a Swedish electronic synchronous reference service, and on the other how interpersonal communication affects the relationship between user and librarian. By using communication theory and establishing a positive relational contact with the user in the electronic environment, the outcome of the reference encounter can be successful for both the librarian and the user. Furthermore, the importance of recognising relational barriers is of great relevance to the relational contact. The scope of this master thesis is to find what relational factors are used and can be used in the interaction between user and librarian.

Biogas mainly consists of methane and carbon dioxide, where methane is theenergy-rich gas, and is naturally created when organic matter breaks down in absenceof oxygen, also known as anaerobic digestion. A biogas plant re-creates the anaerobicconditions inside a digester where the organic substrate is fed into and digests toproduce biogas. The gas is then used to produce energy by combustion and can beseen as a completely renewable fuel.Today, energy from biogas is used primarily by major stakeholders such asmunicipalities and thus the plants become very large with high investment- andconstruction costs. There are currently few small plants in Sweden, even though thepotential for agriculture and medium-sized to smaller farms to become self-sufficientin terms of electricity and heat is great. Farms have a natural stock of digestibleorganic material in form of manure or crops for example, which are constantlyavailable.

Resulting from anthropogenic carbon dioxide emissions, average surface seawater pH is estimated to decline from today's approximately 8.05 to between 7.78 and 8.03 towards 2100. For ionisable organic pollutants, changes in pH can lead to a change in the degree of ionisation, which could influence the ecotoxicity of a compound by altering its bioavailability. In this study, potential changes in ecotoxicity of ionisable organic compounds resulting from ocean acidification are examined. This is achieved partly by conducting a literature review, analysing existing literature that investigates this relationship. Potential changes are also evaluated by examining marine ecotoxicity data for ionisable organic compounds on the watch list pursuant to Directive 2008/105/EC of the European Parliament and of the Council, as well as on the list of priority substances according to the 2022 proposal for amending the Water Framework Directive (2000/60/EC).
