Environmental enrichment is of high importance for zoos. Borås zoo asked SLU (Swedish University of Agricultural Sciences) for a student to perform a bachelor thesis for them. The task was to develop and evaluate environmental enrichment for their Humboldt penguins. A structure was made, consisting of a sinking skeleton with a floating bridge attached to it. It was presented in an area of the pool that the keepers had experienced that the penguins did not use to any extent.

At the end of August 1999, the local government council of Malmö city decided thatthe area known as Kvarteret Bilen would be made available for the European HousingExhibition 2001 (Bo01-mässan). Kvarteret Bilen extends over approximately 80hectars and includes the western parts of the Western Harbour area (Västra hamnen)of Malmö.Kvarteret Bilen as a whole, but especially the western sections of this area, the socalledBo01 section, has been the subject of heated discussions. This is mainly due tothe fact that the ground in question has proven to be contaminated to a certain extentby different chemical compounds. Investigations undertaken during 1998 showed sporadically high concentrations forespecially one chemical group: polycyclic aromatic hydrocarbons (PAH).The first part of the paper describes the use of a mathematical equation (Fetter 1994)to calculate the concentration of PAH from a continuous discharge at a given time byemploying Geographical Information System (GIS). Even the constraints of theequation are discussed, as well as the consequences that follow as a result of usingGIS.The second part of the paper focuses on the connections between the content ofcarcinogenic PAH in Kvarteret Bilen and the ground water level and type of fillingmaterial.

The Baltic Sea is one of the world?s most polluted seas. Increased discharge of nutrients due to greater populations of people, together with a slow water exchange, creates great stress on the sea. Too much nutrients leads to increased growth of algae and causes problem in the ecosystem. Even if we reduce nutrient discharge the problem still exist in the ocean. When algae dies and sinks, more nutritional substances is produced called "internal eutrophication". This phenomenon will grow in the future due to a warmer climate and the problem is spreading towards the coastal zone, which is an important site for fish recreation. By removing the abundance of algae, the nutritional and toxic substances are reduced and the algae biomass can be a future resource for biofuel production..

The aim of this thesis is to describe how service companies through adjustment of the customer?s zone of tolerance can influence customer?s perception of the service during the processes of service delivery and create customer satisfaction. The method used was case study approach utilizing personal interviews, which were conducted at two service companies. The study showed that the aspects of the service that have greatest importance for the customer?s assessment of the service and customer satisfaction among others are personal treatment and that personel behave in the way that makes the customer feel itself taken good care of and unique.

This essay is about the origin, planning and establishment of the European Space Research Organisation's (ESRO) sounding rocket base Esrange outside Kiruna in Northern Sweden. Three main questions are examined. First I show there were not just scientific and technical but also political, economical as well as military reasons to build a European rocket base. Second, I scrutinize the reasons to choose Northern Sweden as the location for the rocket base. As it turns out, the main reasons were the favourable location of Northern Sweden within the aurora oval zone, the proximity of the Kiruna Geophysical Observatory, and the possibility to use a large, although not quite uninhabited, area where the launched rockets could crash.

The purpose of this paper is to describe and analyse the Chinese destination of Hainan, with background in a globalizing tourism destination development, for tourism from Finland and Sweden. The questions at issue are regarding what kind of an impact the status as a special economic zone have had upon Hainan, what kind of conditions there are for tourism on the island, in what form participants of the tourism industry want the development to proceed, what the prevailing trend is for distant destinations for Nordic markets and also regarding what kind of potential there is for organized tourism to Hainan from Finland and Sweden.As a foundation for the paper, I?ve composed a theoretical reference for knowledge of China, Hainan and the study of destinations. The sources of secondary kind are literature related to the subject. The primary sources are mainly interviews, field work done at Hainan has given a concrete and personal knowledge of the place.

According to Swedish school policy documents, every teacher?s assignment is to individually adapt the education to meet every student?s needs. There are no exact guidelines about how to make these adaptations. The purpose of this study is to investigate how six teachers interpret the policy documents and how they, according to themselves, work to achieve this. This study is built on six interviews with teachers who work with children in the ages from seven to ten.

Over the past 40 years 600 000 ha of lodgepole pine (Pinus contorta ssp. latifolia (Engelm.) Critchf.) has been planted in Sweden (280 000 ha on SCA's forest land alone which represents about 15% of the company's total forest land area). In the early 70's SCA situated a number of experimental stands in order to investigate different aspects of the exotic tree, primarily growth rate. To be able to compare the two species plots with scots pine (Pinus sylvestris L.), this species was also planted at the same time and under the same conditions. A number of questions should always be raised when exotic species are introduced in an ecosystem. Invasiveness, the pathogen situation and purely ethical issues should be discussed.

The society of today is dependent of secure transports and deliveries of electrical power. Interruptions in different activities because of fallen trees cost a great deal of money in form of reparations and claimed damages for transport companies and electrical suppliers. Fallen trees along some railway sections are a severe problem. For instance, to repair the damages of the storm of week 5 year 2002, costed 2 800 000 SEK for the line region of Hässleholm. Today, the Banverket railroad company has no norms in general for how close to the railway the forest is allowed to grow.

This paper deals whit the problems concerning social organisation in the county of Dalarna in middle Sweden during the Middle Ages 1050- 1528. This paper also deals whit the every day ife in Dalarna during the same period. In the paper archaeology, ethnology, history and osteology is used in order to create a so accurate as possibly picture of every day life at the farm, the villa and the keep. Each environment is compared to each other in order to try to see the social structure of the county. The geographic frame for the paper is the part of Sweden above the border zone of Limes Norrlandicus, or lower Norrland.The results presented in the paper shows that Dalarna most probably had a flat social organisation in the meaning that the every day life and its artefacts was much the same in all the environments.

Due to global climate change and the rising levels of greenhouse gases (GHG) in the atmosphere, the interest for seeking solutions for mitigation has increased. While much attention has been directed towards technical solutions such as carbon capture and storage (CCS), biogenic carbon sinks has also garnered significant attention. Previous studies have shown that coastal ecosystems such as seagrass meadows and mangroves have a much greater capacity for storing carbon (C) compared to terrestrial ecosystems. That raises the question if other coastal ecosystems, such as coastal wetland forests, that previously haven?t been considered as blue carbon habitats also contribute to coastal carbon sink capacity.

This thesis is basically a design project aimed to find a safe and reliable automatic safety device, which is designed to be suitable for highly automated industrial situations. This device fits with ABB / Jokab Safety?s fence systems. These are built up around machines to create safety distances. The automatic protection device assist the operator in situations when loading or going in and out of the danger zone.

No-fly Zones have been used in three recent conflicts. For every intervention the time taken to achieve the end-state has decreased. It took twelve years in Iraq, three years in Bosnia and only nine months in Libya. NATO was part of the intervention in both Bosnia and Libya, facing almost the same size of opponent, but it took them four times longer to achieve the end-state in Bosnia compared to Libya. The purpose of this essay is to analyze this difference in the time taken to achieve the end-state with a structured focused comparison of Bosnia and Libya based on Robert Pape´s theory of coercion with a focus on No-fly Zones. The results show that the mandate can explain the difference. In Libya NATO had the opportunity, due to the mandate, to use pre-emptive strikes, which they did not have in Bosnia.

The building sector accounted for around a fourth of the total energy usage in Sweden in year 2010 (Energimyndigheten, 2012). Therefore it has become very interesting to achieve a lower energy usage in residential buildings. One way to achieve that is to build so called passive houses. By being very well insulated and have low leakage through the walls, they can reduce the energy usage for heating with a substantial amount. The first passive house was built during the 90?s in Germany; and in Sweden the first passive house was built in Gothenburg 2001.
