Utvärdering av olika sätt att hantera avloppsslam i Värmdö

Important issues for the local authorities are what to do with the sludge produced insewagetreatment plants. The tax for landfill leads to higher costs with 250 SEK/ton. On the 31December 2004 it will be forbidden to landfill sludge.In Sweden the yearly production of sludge is 240 000 tons, counted as DS. The phosphorouscontent is 3 % in sludge. The total yearly production of sludge gives 6000 tons of phosphorous.

Utveckling av differentierade transportersättningar för rundvirskestransporter med lastbil

Approximately 60 million cubic meters of round wood are transported every year with trucks in Sweden and stand for 15 % of all truck transportation in the country. The big amount that is transported results in many haulage companies works in different parts of the country with different conditions to get a good flow on their transports. Today the transport pricing is very general and the payment consists of the unit round wood they are transporting and the distance of the transport. The purpose of this study were, from the freighter and the haulage company?s perspective, try to find ways to change the today applied transport pricing to more differentiated and compare them to historic payment of transportation.

Livscykelbaserad miljövärdering av en ny kontorsbyggnad : En jämförande studie mellan två analysmetoder

This Master?s Thesis aims to illustrate in what ways the two Swedish environmental assessment tools, the Environmental Load Profile and EcoEffect differ and if performed valuations gives different results and environmental goals.The built urban environment causes about half the environmental loading in Sweden. The society?s ambition towards sustainable development has resulted in demands reducing the environmental load. One way to accomplish this change is with the assistance of tools for environmental assessment of the built environment.

Lågtempererad fjärrvärme i Umeå

People in today?s society are becoming more and more aware of how important it is to use energy as efficiently as possible. This is clearly noticeable by an increase in home produced heat with e.g. solar panels or heat pumps heating systems. These changing customer demands forces district heating technology to be redesigned, which is why there is an ongoing research regarding the next generation of district heating - low temperature district heating (LTDH).

Stålbalkars bärförmåga vid intryckning - orsakad av lokal momentbelastning

This master thesis deals with steel girders subjected to patch loading caused by concentrated moments. There exist no good methods to calculate by hand the ultimate resistance for this load case. In ?tunnplåtshandboken?, (Handbook for sheet metal, which is published by SSAB), one calculation method is presented. It?s however fairly difficult to use, because of many calculation steps and many graphs.

Stadsrum och stadsliv - Bebyggelsestrukturers inverkan på kvalitet och innehåll i det offentliga

ABSTRACTToday's modern technological society is constantly evolving and house planning is one area that is constantly creating new technical solutions. By looking back at selected architectural eras during the 1900?s, the idea is to study and analyse three building structures in Gothenburg with a focus on quality and content in the urban space.In order to provide a background for the three selected areas, their history has been studied. The main question for the research is: how do different building structures affect the content and qualities in the urban space?The areas have been selected to represent three typical epochs in Swedish building history.

Användarvänlighet i blötutfodring : enkätstudie för smågrisproducenter

It is possible to affect the feed costs in different ways. By steeping or fermentation the digestibility of the feed is improved for the animals with a natural process in the wet feeding system Steeping means that the feed is soaked some hours before feeding. This process activatesenzymes and improves the digestibility of for example phosphorus in the feed and make it more accessible to the animal. Wet feeding can be fermented or not. Fermentationmeans that the feed has been soaked for a certain length of time so that a biological process is started.

Förluster av nedströmsvandrande fisk vid turbinpassage : En fallstudie för att främja den småskaliga, såsom storskaliga vattenkraften

The expansion of the Swedish hydro power has contributed positively to the reduction of the environmental impacts from the fossil fueled power production. In the same time the extensive expansion has been proved to cause negative ecological and local environment impacts of a stream. This, in turn, has been affecting the biodiversity and fish stock negatively, which has been reduced. One of the underlying problems is the lack of possibility for the fish to pass the plants, but it is also directly correlated to the mortality rate of the fish passing through the turbine, which this study is investigating.The mortality rate has been computed for three different locations in Sweden, Untra, Tännfallet and a third one whose location is confidential, and is denoted as Case 1, 2 and 3. The model used to calculate the mortality rate in this investigation is based by existing blade strike models and knowledge and are investigating the death due to mechanical injuries from collision with a runner blade in the turbine.

Food traceability system for Swedish origin food items : an assessment of the application ?våga fråga - få en bonde på köpet? from a farmer perspective

In June 2013 a debate concerning the consumers? right to a label of origin on food packages was held in the Swedish parliament (www, Riksdagen, 2014). The debate was sparked by some food scandals where labelling was falsely used, claiming something that was not true ? the horse-meat scandal, frozen strawberries infected by Hepatitis A, pork sold as beef, etc. These cases were not only wrong in terms of food safety, but also fraudulent and threating consumers? right to fair origin labelling.

Bekämpning av vita flygare (Aleurotrachelus socialis) i kassava (Manihot esculenta) : fysikaliskt verkande insektsmedel : mortalitet och appliceringsteknik

The study was performed in southwest of Colombia in close collaboration with the interna-tional centre of tropical agriculture, CIAT and supervised from the university of Valle, Uni-valle, Cali, Colombia and from the Department of Landscape Management and Horticultural Technology, SLU, Alnarp, Sweden. The main purpose of this thesis was to evaluate six different non-conventional insecticides and their ability to control whitefly Aleurotrachelus socialis in cassava Manihot esculenta. The aim was also to evaluate the most appropriate application technique for these products which were: Agronim, Biomel, Bioneem, EcoSwing, Coco soap + chilli and L´Ecomix. The products are mainly based on vegetable oil, soap and plant extract and cause primarily a physical contact effect which affirm that it is fundamental to obtain a high coverage of the underside of the leaves, where A. socialis is present.
