The aim of this study was to in laboratory experiments investigate how addition of urea, ECOX and structural materials can optimize sanitization during composting of sewage sludge. Today we strive for a sustainable society and the importance of closing the nutrient loop increases. It has therefore become even more important to safely reuse plant nutrients from human excreta to agricultural land. Partly because it increases the sustainability of society as the world's supply of many nutrients are finite, partly because it promotes human health, both by reducing disease transmission and by increasing Agricultural production. An untapped resource such as sewage sludge that is rich in nutrients and humus-forming materials could replace parts of the commercial fertilizers used in Sweden today. owever, sewage sludge contains undesirable substances such as heavy metals and drug residues, and pathogenic microorganisms.

According to the Water Framework Directive of the European Union, macrophytes should be used as indicators in the ecological and environmental monitoring of lakes. In the member state Sweden the Environmental Protection Agency has elaborated assessment criteria for determining lake status based on macrophytes. The main focus of this thesis is to evaluate the efficiency of the assessment criteria for macrophytes. In addition the concordance between the ecological status classes of the four quality factors included was analysed.The assessment criteria for macrophytes are based on the total phosphorus preference of the respective species. The focus is thus mainly on the nutrient level of the investigated lakes and the environmental problem monitored is eutrophication.

Bakgrund:Fram till den 1 juli 2010 var det obligatoriskt för en såväl grundutbildningsstudenter som doktorander vid universiteten i Uppsala att vara medlemmar i en studentnation (nation). Nämnda datum avskaffades obligatoriet och medlemskapet blev därmed frivilligt.Syfte:Syftet med denna uppsats är att undersöka och belysa vilka konsekvenser nationsobligatoriets avskaffande har fått och kan komma att få för studenterna, universitetet och nationerna i sig.Metod:I denna uppsats har jag, med det civila samhället som teori, undersökt vilka konsekvenserna av nationsobligatoriets avskaffande hittills är och kan komma att bli på sikt. Studien har genomförts genom litteraturstudier, en enkätundersökning bland studenter och genom intervjuer med representanter från nationerna och samarbetsorganet Kuratorskonventet.Resultat/slutsats:Tre år har nu förflutit sedan obligatoriet avskaffades och än så länge är medlemstappet mycket litet. En positiv konsekvens som avskaffandet har fört med sig är att nationerna har knutits närmare varandra och valt att samarbeta i allt större utsträckning.De senaste åren har organisationer inom det civila samhället utsatts för högre krav gällande professionalisering och byråkratisering. Vissa krav skulle ställts oavsett om nationsobligatoriet hade avskaffats eller ej medan andra är mer sammankopplade med avskaffandet, vilket kommer sig av att konkurrensen med andra företag och organisationer i Uppsala har ökat.

This report was written by Sofia Ericson and describes the degree thesis with the title: ?Connections between the growing site of bio fuel, the chemical composition of bio fuel ash and the deposit growth in a bio fuel fired boiler.? The purpose of this degree thesis was to avoid melted deposit growth in the bio fuel fired boiler at ENA Kraft in Enköping. Potassium and sodium are known to lower the melting point of bio fuel ashes and are therefore not wanted in the trees in higher amounts than necessary for the growth. Silicon is also known to be important for the deposit growth but it is not possible to say in general if higher or lower contents of silicon is better. The relation between silicon and other chemical substances is more important than the total amount of silicon.

Europe has, since the economic crisis of 2007, gained increasing social segregation. The gap between rich and poor has increased and the large number of hidden statistics regarding people excluded from the labor market is greater than in many years. Social exclusion has thus taken a toll on community groups that already before the crisis had a hard time getting included. Groups such as young, elderly, immigrants and people with mental of physical disabilities. To curb this development, the European Commission have, since the 2004 directives, enabled public sector clients to, through procurement of goods, services and contracts, include measures that promote social consideration.Social consideration is a term that have been a part of Swedish procurement legislation since 2007, and was updated in 2010.

På uppdrag av SWECO Management AB utreds möjligheten till att kunna se korrelationer mellan åtgärder på en fastighet eller i dess omgivning och ett förändrat fastighetsvärde. Denna information skall vara SWECO till gagn i upphandlingssituationer, för att lättare kunna visa för beställaren om att tjänsten i fråga kan leda till ett ökat fastighetsvärde. Med utgångspunkt i den begränsade litteraturen, har information främst samlats genom en intervjuprocess med representanter från fastighetsbranschen. För att få ett brett perspektiv i ämnet, har representanter med olika befattningar, olika lång erfarenhet och med varierande utbildningar intervjuats. I studien görs avgränsningar om makrofaktorer, såsom konjunktursvängningar, ränteförändringar, finanskriser, låneinstitutens förändrade låneregler etc.

This degree project summarizes five years of education at the landscape architecture program at the Swedish University of Agriculture Sciences, SLU, Alnarp and the School of architecture at Royal Institute of Technology, KTH, Stockholm. The project has been carried out by Lovisa Berg and Per Crona in collaboration with DRIFT Scenkonst. This master project is based on the ongoing transformation of a former mining site in Ställberg, Bergslagen situated in central Sweden. The organization DRIFT is in the process of recreating to former industrial mining site as a green cultural center. Their field of artistic examination concerns existential questions connected to the site. The aim is to offer a place for both performing and experiencing contemporary performing arts in Bergslagen. Our objective is to contribute to the growth of the performing arts project and to demonstrate in concrete terms how a conversion of a mining area can be completed, while taking into account both its history and its new function.

From the pre-Roman and Roman Iron Age, a number of different fossil agrarian landscapes can be found in southern Sweden - clearance cairn areas, celtic fields, stone-wall complexes and geometrically laid-out strip fields. With two different comparative analyses, this paper tries to explain some of the differences between clearance cairn systems and the other fossil field systemsThe shape of the early Iron Age agrarian landscape varies between different provinces of southern Sweden. At Gotland, celtic field systems were laid-out before 500 BC. In Småland at the same time, areas with clearance cairns were created. How can the difference be explained? The different physical appearance of clearance cairn areas and celtic fields can be explained by the different ways to handle the ard in till and in sandy soil.
