Gestaltningsförslag av gravplatser ur ett miljöperspektiv
Environmental issues and ecology is something that is discussed by the Climate board of the UN and by our Swedish politicians. The first part of the thesis deals with the effects of emissions of greenhouse gases in our atmosphere. There is a discussion about what counts as greenhouse gas. Interviews have been made with two growers of annual plants and one interview with a person who has worked hard to increase the use of perennials in his work place, Mjösund?s cemetery.
Utvärdering av urbana ekosystemtjänster: Verktyg och certifieringssystem.
Denna rapport behandlar utvärdering av urbana ekosystemtjänster på stadsdelsnivå. Eftersom ökad urbanisering leder till ökad belastning på urbana ekosystem är det viktigt att både exploatering och etablering av grönområden sker på ett hållbart sätt där ekologiska, sociala och ekonomiska faktorer inkluderas. Detta kan delvis uppnås genom att villkor i verktyg och certifieringssystem inkluderar aspekter för urbana ekosystemtjänster. Det undersökts hur certifieringssystemen BREEAM Communities och CASBEE for Urban Development samt verktyget Grönytefaktormetoden behandlar sådana urbana ekosystemtjänster. Analysen utgår från en föreslagen kategorisering av urbana ekosystemtjänster.
BAMBUVISKOS ? En hållbar fiber för framtiden?
Naturskyddsföreningen gav författarna uppgiften att undersöka förekommande viskosprocesser och alternativa regenereringsprocesser, detta för att identifiera hur hållbara de är ur ett miljöperspektiv och vilka processer som går att applicera på bambu. Detta för att se möjligheten att märka bambuviskos med Bra Miljöval och för att klargöra frekvent uppkommande frågor angående bambuviskos. Syftet är att se på de olika processernas kemiska innehåll samt vilka utsläpp de orsakar till luft och vatten. Ett delmål med rapporten är att den ska kunna användas som material vid vidareutveckling av kriterierna för Bra Miljöval Textil. Resultat som erhållits vid jämförelser av studerad litteratur är att de betydande faktorerna för miljöpåverkan från massaframställningen samt viskos- och lyocellprocessen beror av: använda kemikalier i processen, energianvändningen och vilken typ av energi, möjligheten till rening av utsläpp till luft och vatten samt återvinning av energi och kemikalier.
Olja välsignelse eller förbannelse?! - en studie av oljans effekter på institutioner och institutionell förändring
AbstractOil rich states all over the world share a common feature. They are less likely than other states, depending on other resources, to be ruled democratically. In this essay Saudi Arabia has been studied with the purpose of trying to find which mechanisms that lie behind why oil rich states do not have institutions or institutional change that promotes democracy.Saudi Arabia has the world's largest known reservoir of oil. The oil brings huge revenue each year to the Saudi Arabian government. Why have Saudi Arabia not developed democratically when their economic growth suggests that to be a natural step? Under the framework of historical institutionalism and path dependency theory, I have used process tracing trying to track the mechanisms behind Saudi Arabia's authoritarian rule down.
Undersökning av en industrifastighets material och resurshantering enligt miljöcertifieringssystemet LEED
Miljöcertifieringssystemet för byggnader, LEED (Leadership in Energy &
Environmental Design) lanserades 1998 i USA av USGBC (United States Green
Building Council). USGBC är en icke vinstdrivande organisation, vars mål är att
bidra till utökat hållbart byggande. Skanskas första byggnad som certifierades
enligt LEED färdigställdes 2001 i den amerikanska delstaten North Carolina. I
slutet av februari 2009 offentliggjordes det att Skanska skall införa systemet i sin
Nordiska organisation.
Undersökningen som genomförts handlar om ett av LEED New Constructions sex
delområden, Materials & Resources. Materialhanteringen för ett byggprojekt som
Skanska uppfört har analyserats för att avgöra huruvida det skulle kunna erhålla
poäng vid en certifiering enligt LEED.
Privata skogsägares inställning till frivilliga naturvårdsavsättningar samt kvalitets- och tillväxthöjande skogsskötselåtgärder :
The business mission of Norra Skogsägarna is to achieve a profitable forestry for the private forest owners. With this as a background it is of interest for the forest owner association to know how forest owners think about voluntary retentions, the methods of increasing production and quality and if there are differences between those who have chosen to certify their forest and those who haven?t. This kind of knowledge is of importance, to in an effectively and adjusted way, help the forest owners achieve a profitable forestry.
The objective of this master thesis is to increase knowledge about private forest owners? opinions of the methods of increasing production and quality and to what extent these methods are used.
Gas som bedövningsmetod vid slakt av slaktkyckling :
Electrical stunning is the method that has been used in Sweden to stun broilers prior to slaughter. However, for reasons of animal welfare and meat quality, research has been made in the EU to develop new stunning methods. Gas stunning is now regarded as the best alternative. In this study literature has been reviewed with focus on different gas stunning systems and observations have been made at two different slaughterhouses regarding animal welfare before, during and directly after stunning. At one slaughter plant carbondioxide was used in a two-stage system where the birds were standing on a conveyer belt during the stunning procedure.

Hemmet, kvinnan och moralen : I Malmö stads barnavårdsutredningar 1930-1936
This study, a narrative analysis of it, deals with the term, home, its importance and the use of it by Child welfare investigators in the city of Malmö between the years 1930-1936. Commonly used and acknowledged, home stood for security and order while the term, street, had just the opposite meaning. Living in the countryside symbolized health and sensibility, while city life was considered to be cramped, dirty and immoral. The responsibility of achieving the liberals and conservatives ideal of a sunny, clean and orderly home was given to the woman of the house, as was the task of keeping the home morally correct, and providing the necessary atmosphere for proper upbringing of the children. Consequently, the basis of theory, using Karl Marx and Friedrich Engels in regards to the conflicts between the upper and lower classes, and even theories of Jane Lewis of woman´s connection to home and family, have been the grounds for the study.

Utvärdering av effektstyrningssystemet EnergiDirigent® ur ett miljöperspektiv
Energy Director is a control and measuring system for energy consumption and is part of the product portfolio of E.ON AG for more efficient use of energy, offered to business customers. As of today, the system has only one parameter of control, namely power, and the objective of this essay has been to investigate whether other ones could be added. The emphasis is on the environmental perspective, which is why carbon dioxide has served as an example for this parameter in question.Parallel with the study of Energy Director electricity on the margin, calculations of carbon dioxide equivalents and also the Swedish trade of electricity have all been highlighted. Results indicate that when reductions in energy are made it is endorsed to omit from electricity on the margin rather than some mean distributed electricity, under certain conditions, and in addition the calculations of the reductions should be modified regarding the efficiency of the power stations fuelled by lignite and bituminous coal. Sweden practices trade with the Nordic countries as well as Poland and Germany.
ESC-analys och studering av knack på en "Diesel Dual Fuel"-motor
A one-cylinder research engine has been used for studies with a Diesel Dual Fuel concept (DDF). DDF is a concept that utilizes a pilot diesel injection to ignite a homogenous natural gas/air mixture. Emissions and engine efficiency have been analyzed in an emission cycle called European Stationary Cycle (ESC) and the knock/pre-ignition problems with this type of engine have been investigated.At low and mid torque levels, an early diesel injection around 60 crank angles degrees (CAD) before top dead center (TDC) was used. At these loads raw NOxemissions was below EURO 6 level (0.2 g/kWh). NOxwas at EURO 5 level over the complete ESC without after treatment and with SCR at high loads it should be possible to reach EURO 6.One issue with DDF is the high HC emission levels.
Utsugande köksfläktsystem : För passivhus
Hus byggs idag allt tätare för att möta högre miljökrav, ställda av både konsumenter och politiker. När hus byggs täta minskar luftläckaget genom klimatskalet. Tack vare det sänks energiåtgången då nästan all luft styrs genom en värmeväxlare. Tätheten i de nya husen har lett till att utsugande köksfläktar inte fungerar som de ska, beroende på att de behöver mycket luft. I detta projekt utvecklades ett utsugande köksfläktsystem för passivhus, de allra tätaste husen på marknaden.
Fältskiktsarter i naturlika planteringar : vilka råd kan ekologer ge?
This paper appeals to professionals working with green questions. It intends to create a discussion about which plant species that can be established in a fieldlayer of a naturelike planting on fertile agricultural land. To initiate the essay, a studie of which values that can be connected with an establishment of a fieldlayer was performed . A part of Tor Nitzelius Park in Alnarp, a so called naturlike planting on fertile agricultural land, was used as a model for the choice of species. With the aid of soil values, photos and a list of current species, interviews with four ecologists were performed.
Observiaire och film som analysmetod för cykeltrafik : En fallstudie på Götgatan i Stockholm där omställningen till supercykelbana utreds
The goal of this thesis is to analyse whether the method ?Observiaire? is of any use for traffic analysis. The method consists of analysing film material, preferably before and after changes are made to an area, by answering a survey for the users that are observed within the population. The method also opens up for deeper qualitative analyses which are rooted in the quantitative data collected from the survey-study. In this study we analyse the method by applying it to the case study of the changes made at Götgatan in Stockholm, where a green wave was implemented and the bicycle road widened.
