As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.

To plan and build a garden in Dubai has other conditions and challenges than what you experience in Sweden. The heat, wind and lack of water makes the need for durable plants, a good design and landscaping important if you want to have the opportunity to use your garden during most of the year. The soil is poor of nutrients, alkaline and sometimes saline, witch makes supplying the soil with organic material and various fertilizers necessary if you want to be able to plant a bigger range of plant material in your garden. Another important part is to provide your garden with a good irrigation system that should be put into the ground before planting so that the plants are given a more even irrigation. It?s relatively green scenery you meet and to me it?s in a way surprising since the country with its climate is rather harsh for the purpose of supporting plant life.

This master thesis reviews advances in detection and diagnosis of static friction (stiction) in control valves. Control valves suffering from stiction results in oscillating control loops which in turn decreases both the process stability and reliability. Perstorp AB sees a necessity to automatically detect stiction in valves before the effects of the malfunctioning valves have become too severe. This thesis presents an introduction to maintenance, control loops and how stiction in valves can affect performance of control loops.A selection of methods presented in the literature are introduced and examined using normal operating data from the site in Perstorp. Common for all selected methods is their intuitive ideas and that they are based on normal operating data and minimum amount of process knowledge.

The aim of this study is to investigate methods of collection development, the users? influence on selection and quality aspects, focusing on non-fiction literature in Swedish public libraries. To find out opinions of collection development, I use the method comparative literature study. Antonio Gramsci?s concept hegemony forms the theoretical background, and hegemony as concept is related to a library context by using Maj Klasson?s text on the librarians? different positions of authorities.

Sustainability Reporting has emerged and transformed over the past decades as a voluntary practice by companies across industries that desire to show proof of good conduct and environmental; social; and economic responsibility. As industrial food production is one of the largest contributors to contemporary environmental problems, it might be expected that reporting within the industry would be both well established and well understood. Unfortunately, it is neither. In light of the food industry?s considerable environmental impact and the growing popularity of plant-based food as a more sustainable alternative to dairy products, this paper assesses and briefly discusses the Sustainability Reporting of two companies in the plant-based food and beverage industry. The research was designed to compare the practices of Europe-based Alpro and US-based SoDelicious, and this study has two major purposes: to describe the reporting of the case companies and to subsequently compare their practices to the other as well as to global reporting standards. The empirical study in this paper was conducted through content analysis.

Today, there are few industries left in our cities. Industrial areas thatare located in urban settings close to water or city centers are oftenreplaced by housing. In my thesis I want to explore how such industrialsite located in an urban setting can be transformed into anindustrial park where the industrial structures are saved. By approachingthis type of environment in a positive manner, I wish tohighlight the potential aesthetic and functional value in the existingindustrial structure. Through the transformation and design of anexisting industrial site I will convey the previous use and history ofthe place.The wastewater treatment plant, Kungsängsverket, is located in thedistrict of Kungsängen in the southern part of Uppsala.

 This report will describe a project between two students from Karlstad University and Markus Norström from Hovercraft solutions. The project aim was to develop a cabin for the hovercraft 380TD. The project was divided into two sub parts; one concerning the design of the cabin and one concerning the engineering. Throughout this rapport you can follow the engineering part of the project. The project has followed a systematic product development process resulting in optimized results for material selection and engineering solutions.

This report will point out the income for a scania plant production farm, this has been estimated through a case study. The outcome of this report will later be used to calculate a reasonable leasehold charge. This case study is solitary based upon this particular studied farm, at this very point, and can therefore not be used as a general guide. The reason why this particular scania plant production farm has been selected, is because the author is born and raised at the farm and has the intention to run the farm in the future. The chosen farm for this report is based in the southwest of scania and cover 300 hectare of plant production. The crop rotation consists of autumn wheat, sugar beats, spring wheat, spring barely, winter rape and fallow. The farm owns all machinery required.

Hemp is a versatile plant with many uses that has been around for thousands of years. The plant is highly adaptable andwill cultivate in almost any soil. It has excellent remediation properties and has shown to be relatively consistent when itcomes to crop yields. The aim of this literature survey is to examine how hemp can be used to be considered asustainable energy crop in Sweden through database searches and interviews. Hemps characteristics as an energy cropand its remediation properties is evaluated and compared with other plants that are used in Sweden.

Migration is a worldwide phenomenon that has occurred for thousands of years in a vast variety of species. The general knowledge of migrating animals is poor even though billions of animals from a range of different groups migrate every year. The human impact on migrating ungulates is high and many populations are declining globally due to direct and indirect causes. Hence it becomes vital to study the migration phase and the habitat and resources selected during migration. The objective with this study was to identify the habitat characteristics and resource selection of moose during migration and compare the selection between different seasons and utilization distribution (relative frequency distribution for the points of location of an animal over a period of time) categories.

Because of the currently large recruitment needs within the Swedish nuclear powerindustry, it is necessary to recruit trainers from other recruitment groups than that ofexperienced operators at nuclear power plants. The foundation for a trainingprogram regarding these recruitment groups, here called ?aspirants?, has in this thesisbeen prepared. It contains a suggestion for main topics in the program. It also includesdiscussion on the balance between forms of education and a concrete example ofhow a lesson could be performed.These suggestions has been developed through analysis of interviews and surveyresponses from student groups most suited for the propositioned trainee program,and individuals with service as a trainer or closely linked to training activities withinthe industry.The analysis suggests that the candidates gets, besides the opportunity to practice asoperating staff before the theoretical training begins, a training program, tightly boundto the power plant with multiple instances of practice and the chance of going intothe power plant and see how things that are being raised in theory, look in real life.The practice, in addition to helping to create an understanding of the plant, it will facilitate networking with the operations staff to build a relationship and trust.Candidates should have plenty of opportunity to educate and see both other aspirantsand experienced trainers train.

Certain microbial residents from composts are known to possess the ability to suppress soilborne plant pathogens. Trichoderma spp. and Gliocladium spp. are commonly found in composts and are perhaps the most wellknown hyperparasites of fungal pathogens, which may also be naturally present in compost. Trials have many times proven them to be effective against plant diseases caused by soilborne pathogens such as Pythium spp., Phytophthora spp.

In Lake Vänern, Sweden, there is an endemic population of Atlantic salmon (Salmo salar L.) that lives its entire life in fresh water. The salmon is hindered from migrating to its natural spawning sites in the northern part of the River Klarälven by nine hydro-electric power plants. None of the hydro-electric power plants have fishways so that salmon migrating upstream or downstream may pass. In the current situation, the upward migrating salmon are caught in a fish trap at the most downstream located power plant in Forshaga. From there, the salmon are driven in a truck, past eight power plants and released a few kilometers upstream of the eighth power plant at Edsforsen.

Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.
