In today?s world urbanisation is an on-going process, cities are growing and becoming denser, and places for recreation gain value. Therefore, urban parks are much appreciated by people living in cities. When the first public parks where planned, their main function was to increase health, hygiene, education and social life. In the middle of 19th century the meaning of public parks to people?s wellbeing gained attention and parks were planned to provide space for lively activities. This paper focuses on parks? activities.

This thesis provides a good introduction to the American environmental certification system LEED, Leadership in Energy and Environmental Design, and trough compar-isons between Sweden and the United States an explanation to the systems design is given. The work is closely linked to a LEED Core & Shell project in Stockholm, Swe-den, where the goal is to reach the second highest rating in LEED - Gold.This thesis gives a broad description of the LEED system and a more profound study of the energy sector, Energy and Atmosphere. Here, for example, an analysis has been made of how the energy consumption of an imaginary building designed according to the requirements of the BBR (Swedish building code) performs in comparison to the Baseline building in LEED.The existing model of Borgarfjord 3, which served as a case study in this work, has al-so been modified to investigate the energy savings that could have been achieved by adding extra insulation to the building. A description of the problems, regarding how the Swedish district heating system (DES) is treated in LEED, is given as well as the suggested modifications. This is an issue that will be pursued during the process of shaping a new, international, version of LEED due to be launched 2012..

Fleets have the ability to affect an adversary?s use of the seas for transportation. Nations have in numerous occasions exercised this power in order to ravage their opponent?s trade in times of conflict with the purpose of diminishing their military might. Great naval thinkers like Mahan and Corbett have described this use of seapower during conflicts in great depth but theories regarding the use of seapower to affect a nation?s peacetime economy in order to achieve limited political goals is lacking.

This thesis examines the deregulation reform of the Swedish railroad industry, focusing on passenger transport between 1988 and 2005. The purpose of the thesis is to examine the effects from the deregulation reform on prices, market concentration and to determine whether SJ (the state owned incumbent) has been conducting strategic behaviour in order to prevent new entrants to the market. The chosen method consists of interviews with the MD at SJ between 1988 - 1998 Mr Karl-Erik Strand, the transportation researcher at SSE Mr Gunnar Alexandersson. Statistical sources and companies financial reports have also been used. The results that I have found were besides the fact that the market concentration is still significant high and the profitability among the operators low, is that the prices has increased more than CPI during the period but the competitive tendering has resulted in lower government subsidies after the deregulation.

Syftet med denna studie var att undersöka vilka effekter luftföroreringar har på lavar och grönalger som växer på lindar, genom att jämföra lavfloran i urban miljö och i landsbygdsmiljö. Mer specifikt var syftet att utreda hur avstånd till närmaste väg, trafikintensitet och trädets exponerade respektive icke-exponerade sida gentemot en väg påverkar lavfloran i urban miljö. 18 utvalda lavarter samt grönalger eftersöktes på 86 lindar i urban miljö och 37 i landsbygdsmiljö inom Norrköpings kommun. Resultaten visade att artantalet, samt förekomsten och täckningsgraden för flertalet lavar var större i landsbygdsmiljö jämfört med urban miljö. Kortare avstånd till närmaste väg och hög trafikintensitet hade negativ effekt på flertalet lavar.

The design of the building envelope affects the energy consumption of a building. As the energy requirements for new buildings are becoming more demanding, the performance of the building envelope must be improved. Energy efficiency and durability are important attributes to consider.This report includes investigations of the building envelope, moisture and passive solar energy. It is based on the analysis of two different buildings with different designs. These buildings stand as reference for two of the companies who are working on a new, climate smart, residential area in Uppsala, Sweden.Studies and analyses on energy consumption and moisture transportation were made.

Two species of bees in the genus Apis, real honey bees, has long been of interest for man. These two are the European honey bee, Apis mellifera, and the Asian honey bee, Apis cerana. In Vietnam, beekeeping is of great importance, both with A.cerana and A.mellifera. The aim of this project was to investigate if the introduction of the European honey bee in Asia has affected the Asian honey bee, and whether different pathogens from A.mellifera have been transferred to A.cerana. Totally 40 samples, 20 from every species, were analysed for 8 different viruses.

Operabyggnaden placeras längst ut på piren och tar hela dess udde i anspråk. Operan riktar sig mot staden. Byggnadens storlek och koncept kräver viss rymd och ljus runt sig varför valet av plats blev naturligt. Den stora operavolymen skärs itu i flera delar och de olika volymerna binds sedan samman av en stålkonstruktion som på vissa ställen fungerar som ett orangeri medan den på andra ställen är en öppen pergolastruktur. Växtligheten används som ett material och ger intressanta rum, skuggspel och klimat. Orangeriet/pergolan löper igenom och runt byggnaden och såväl personal som besökare rör sig på gångar genom orangeriet/pergolan och upplever olika typer av rum, på olika nivåer. En önskan med uppdelningen i flera volymer är dels för att få in ljus på ett vackert sätt i en annars djup och mörk byggnad, dels för att försöka bryta ner skalan, samt även för att kunna ge personalen bra arbetsmöjligheter.

The ferry traffic to Gotland is essential for the island?s ability to live and develop. Yearly, it transports 1,6 million passengers, 500 000 personal vehicles and 750 000 lane meters of freight with four Ro-Pax ferries. The traffic is controlled and subsidized by the Swedish government since 1971 in order to guarantee the inhabitants and industry of Gotland a satisfactory transportation service. As a consequence of the past decades increased traffic quality, mainly due to a decrease in crossing times, the traffic?s environmental impact and costs has also increased.The Master Thesis proposes a new energy efficient traffic arrangement that satisfies the users? preferences in the same extent as today.

The initiative for this project was taken by Benteler Engineering Services, as a result of having identified areas of improvement, in designated accessible areas like the wheelchair spot onboard buses. Depending on a wheelchair to be able to move around can understandably be challenging.Public transport is a common good in today`s society, however despite the measures taken towards adjusting to accessible needs, the majority of those being disabled chose different alternatives of transportation. This is due to reasons such as the drivers' poor attitude, furthermore the limitations of the space allocated to accessible needs, as people with strollers also use these spots onboard. Also, some wheelchair users find the rides unsafe, as they could easily fall over during without the appropriate space for them onboard the buses etc. These are only a few reasons why other options are sought out, i.e.

In this thesis, the Train Power System Simulator (TPSS) has been compared and verified with the commercial simulator TracFeed® Simulation (TracFeed). The basis for the comparison was a given part of the Swedish railway system, with steel transportation trains. Primarily, emphasis was placed on running time and energy consumption in simulation results. Two transformer systems were analyzed, booster and auto transformers. The high voltage transmission line, parallel to the railroad track, was disconnected in some simulations.

Biodiversity consists of all life on Earth and in all forms. Biodiversity is often discussed at three levels: ecosystem, species and genetic variation within species. Biodiversity also provides many of the ecosystem services performed by nature and that we depend on, including cultural services such as aesthetic values, education and recreation. In Sweden the environmental objectives are central; there are 16 environmental quality objectives, and "A rich plant and animal life" is one of them. Conservation and sustainable use of biological diversity is a prerequisite for achieving also most other environmental objectives. Another environmental quality objective that is tied to a rich biodiversity in cities and biodiversity is "Good built environment" where cities, towns and other built environment should provide a good living habitat and contribute to a good environment.

The essay is written at the request of Nyköping municipality park management by PatRadestedt who wanted a design proposal for one of the five courtyards at the Tessin Schoolin Nyköping. The Tessin School is located 2 miles from the center of Nyköping and the schoolhouses approximately 900 students. To make a design proposal for the courtyard that lies atthe canteen I decided from the outset that I wanted to take some of the Tessin SchoolStudents' opinions and wishes regarding their own outdoor spaces. I had a workshop witheight students from the arts program with the image orientation in which they had to drawand tell them what they wanted to do in the courtyard. The outcome of the workshop, Iused to move forward in my future work with a concept that fit into the environment, wethen apply it in my final design proposal.

ABSTRACTA defect implantation process is the major reason for unexplained infertility. Estrogen andprogesterone are steroid hormones preparing the endometrium for implantation. They mediatetheir effect through their receptors: estrogen receptor alpha and beta and progesteronereceptor A and B, respectively. Leukemia inhibitory factor (LIF), which is also important forimplantation, mediates its effect through LIF receptor and the coreceptor, gp130, and is downregulated by suppressors of cytokine signaling 1. The aim of the study was to compare thelevels of the steroid hormone receptors and LIF related factors in the endometrium of twogroups of women with the diagnosis unexplained infertility: one that became pregnant afterassisted reproduction and one that did not become pregnant.

Ad Astra är en cirkushall, högt beläget på en skogsbeklädd kulle ca 10 minuter från Alby centrum. Här samlas hela Cirkus Cirkörs verksamhet under ett tak: elever, lärare, administration och besökare.Promenadvägen från Albys tunnelbana leder fram till ett torg med den nya byggnaden som fond. Ett strikt grid av 58 stålpelare definierar ett uterum på byggnadens tak som sluttar upp mot en kopparkub bland träden. Här skapas möjligheter till allt från utomhusföreställningar till picknick i ett landskap som subtilt smälter samman med den bakomliggande skogen. Gränsen mellan natur och struktur suddas ut samtidigt som taket ger en oöverträffad utsikt över Alby och Albysjön.Internt är byggnaden tvådelad med en publik, öppen del och en sluten,flexibel hallösning.
