AbstractWith this c-composition, I am trying to give a view over what has happened in the political area and the issues that concerns environmental aid. My analyze starts in the 60-ies when the environmental debate took of. It continues trough the 70-ies, 80-ies and ends in 1994 with the report that considers the UN-conference in Rio de Janeiro 1992, ?Sustainable Aid? and what the results of the more and more important issue ?sustainable development? has offered the Swedish government ant there work with environmental aid.The question issue is: At what time in history, did the Swedisch government start to addrsess environmental aid? How did the environmental aid come to be addressed and developed in the political area from the Brundtlandreport ?Our common future? from 1987 to the UN-conference in Rio de Janeiro 1992?The result is that the environment is getting more and more important in the political arena as the knowledge about the escalating crises with the environmental problems are being taken more seriously. The problems with the environment has to be considered together with the rest of the aid- and developing questions like economy and the struggle to reduce poverty in the world.

Drinking water is produced from raw water and is either from groundwater or surface water. This thesis aims to find out if the cleaning process of raw water is sufficiently effective. This is important because consumers are otherwise at risk of waterborne infection caused by pathogens. There are three groups of pathogens; bacteria, virus and parasite. These have different characteristics which mean that they require different water treatment to be separated.

As the information society becomes increasingly flooded with digital images, the need for efficient image retrieval systems increases as well. To handle the vast amounts of data involved, the indexing process needs to be run automatically, using content-based descriptors extracted directly from the digital image, such as colour composition, shape and texture features. These content-based image retrieval systems are often slow and cumbersome, and can appear confusing to an ordinary user who does not understand the underlying mechanisms. One step towards more efficient and user-friendly retrieval systems might be to adjust the weight placed on various descriptors depending on which image category is being searched for. The results of this thesis show that certain categories of digital images would benefit from having extra weight assigned to colour, texture or shape features when searching for images of that category..

The aim of the study is to investigate attitudes about rapists and to determine whether it is felt that they need treatment, imprisonment or a combination of the two. The study examines differences in attitudes between two different educational groups. The first group of students is comprised of those studying on programs that lead to careers working with people, whilst the other contains students who will work in business administration. The investigation also includes views on which punishment alternative the informants believed to be the most appropriate. The same differences are also investigated between gender and age.

Kemisk krigföring i form av luftburna gifter har förekommit i många historiska kontexter. Trots att luftburna gifter, som till exempel giftig rök och gas är likartade företeelser, har inte forskare kunnat enas om äldre former av denna krigföring är jämförbar med den moderna. Huvudorsaken är att deras analyser saknar teoretiska perspektiv som belyser hur respektive   kontexts kemiska förutsättningar påverkar krigföringen.Syftet med den här undersökningen är att jämföra ett modernt nyttjande av luftburna gifter, tyskarnas första klorutsläpp vid Ypres 1915 med ett forntida exempel, den moistiska skolans användande av brandrök som gift under århundradena f. Kr. i Kina.

At Degermyran landfill, situated in the municipal Skellefteå, a leachate treatment system was installed in 2005. One of the aims of this study was to investigate how well the treatment system works by using data from chemical measurements made on the leachate before and after treatment. Further this study had the purpose of investigating how the predicted climate changes of the 21st century will affect the amount of leachate generated at Degermyran by using a modified version of Thornthwaites water balance model. The treatment system has the ability of reducing manganese by 90 %, nitrogen by 73 % och TOC by 79 %. By the turn of this century the amount of precipitation that percolates the waste at Degermyran will be between 254 and 298 mm, depending on the amount of greenhouse gases that will be released in the future to come.

The aim of this work is to analyze if a change in the benthic community can be detected two years after a restoration of a small stream. The samples were taken in a small stream at Tinnerö Eklandskap just south of Linköping. In addition to the restored area, two reference sites upstream and downstream of the restored area were sampled to compare to the restored site. The method used for sampling of benthic fauna in the stream was kick sampling. ASPT, Berger-Parker and Renkonen-indices were used to find out if there was any difference between the reference areas and the restored area.

In this project a simulator has been developed (in C++) with the purpose of illustrating how changes in environmental regulations, tax levels and other policy measures affect the composition of an energy system. The aim of the project was to investigate how energy companies? investment strategies are affected when changes in economic and environmental conditions occur. A standard scenario has been created based on current Swedish conditions, but the user can create new scenarios and set parameters freely. The user is tasked with building power plants to supply the city/region with district heating and electricity during a pre-set number of years. When the simulation is finished the result is graded in the following categories: economy, environment and quality. To evaluate the simulator three scenarios were created (?early 20th century?, ?reduced environmental control? and ?future?) in addition to the standard scenario and these were compared with each other by examining how a select group of power plants perform under the given conditions.

When one experiences a place, it is a complex composition of both social and spatial factors.One of these spatial elements, is scale, which is influenced both by the room size and itsproportions. This paper aims to explore both large and small scale concepts and thus increasethe understanding of how scale directly and indirectly affects the experiences and uses ofurban space.First, is a theoretical discussion of scale in relation to aesthetics and the differencesbetween real scale and perceived scale. Next, is an analysis of spatial perception usingexamples from two existing sites. One, which is understood to have been planned in a largescale and one which is understood to have been planned in a small scale.When preparing this paper, the focus quickly became the importance of scale as itrelates to street spaces. The perception of a street usually takes place while in motion, whichforces it to be perceived in sections.

This bachelor thesis discusses firefighting and the use of portable fireextinguishers in the salvageof historic artefacts focusing on textiles. It also looks into the use of multi-purpose dry chemicalextinguishers in a textile context and the impact the actual dry-agent has on textiles afterfirefighting.Literature studies, interviews and tests on different textiles were carried out to write this thesis.During the tests textiles were exposed to the dry agent and also to dry agent plus water toinvestigate the difference in residue. After vacuumcleaning it was clear that when the textile wasexposed to dry agent and water it was almost impossible to remove the chemical without rinsingin water.By examining the residue left on the textile using SEM it was possible to see if a textile was aswell decontaminated after vacuum-cleaning as it looks to the eye. We know that the dry agentoften consists of ammonium phosphate which acts corrosively on many materials and one canassume it damages textiles as well after longer exposure.Buildings housing cultural collections are vulnerable as we cannot easily replace ruined materialwith new.

In this report a systematic working procedure for risk classification of processing equipment from a maintenance point of view is described. How this system has been worked out is also an important part of the report. The classification system is adapted for use in complex processing plants. Preemraff Göteborg has been subject for the underlying study and application of the system.The system aims to give a good overview of the maintenance related risks at the plant. Furthermore, the analysis result is a good motivation for the suggested maintenance activities and as motivation for extended or decreased maintenance resources in total.

No summary of feeding recommendations for foals exists today, which is why this subject was chosen for a literature study. The aim of this study was to describe nutrient requirements of healthy full term foals and how the feeding should be designed to raise foals if they lose their mother. Mare milk composition changes during lactation to meet the requirements of the suckling foal. Foals are born with enzymes in their small intestine and the concentrations of these follow the consumption patterns of the foal. Microbes colonizes the gut as the foal becomes older and these changes cause foal diarrhea.

The aim of this project was to look into ten small sewer systems in the municipality of Laholm, in Sweden, in order to work out common assessment grounds for them. The sizes of the systems for purification of wastewater were within the range of 25 to 2000 population equivalents. Our method was to study literature, the laws and regulations applicable and the files at the municipality. The conclusion is that every sewer system is different and every situation is unique. We concluded that based on laws and assessment grounds sewer systems equal in size and pollution load ought to have similar demands attached to them.

This study aims to investigate the domestic and work organization at the mansions located in the south of Västmanlands county years 1705-1849. The study takes into account the manors' size, ownership, owners' status and social changes. The study includes both large manors with noble owners and smaller manors with bourgeois owners.  The study examines how the households were formed, how they changed over time and how thet may have links to the Manor's ownership and size. The organization of labour is studied on the basis of how it changed over time and what it may have links to the owners ' status and the manors size. The focus is to answer how the connection was between household size, its composition, organization of labour and the owner?s status in the society.  Also if a difference can be seen between the strategies of the noble owners compared to the bourgeois owners..

Small pieces of plastic, termed ?micro plastic? in the oceans derive mainly from degradation of big plastics such as beach littering, but also from sources of direct emission from e.g. beauty scrubbers and synthetic sand-blasting. These micro plastics are ingested by marine animals ? mistaking them for plankton ? or via prey.
