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.
Förstudie för en vindkraftpark på Malmölandet i Norrköping : En undersökning av förutsättningarna för en vindkraftpark på ett sen tidigare planerat område
This is a feasibility study that examines various aspects of building a wind farm on Malmön in Norrköping. The feasibility study deals with interests of conflict, park design, electrical connections, production calculation, financial calculations and operating- and timetable.The report is divided into two distinct parts. First a theoretical part, which deals with conflicting interests, park design and electrical connections. Second a part with simulations dealing with production calculations, and financial calculations.Opposing interests are mapped so that problem areas can be found, and help put focus on the right places at a future environmental impact assessment (EIA). There are a number of areas where planners have to assess on an EIA, this thesis point on the most important areas.
Simulering av kombinerade rundvirkestransporter och kartläggning av dess effekter på servicedimensioner
Genom den rådande utvecklingen inom svensk rundvirkeförsörjning, som går mot större och färre produktionsanläggningar, blir medeltransportavståndet allt längre. Detta ökar behovet av järnvägstransporter av virke och förändrar därmed de andelar som bil- och järnvägstransporter utgör av den totala virkesförsörjningen. Ytterligare påverkan på transportval åstadkoms av varierande järnvägsnät och industriplacering i förhållande till detta.
Syftet med denna studie var att utveckla en simuleringsmodell för att kartlägga effekterna av systemkonfiguration och omvärldsfaktorer på leveransprecision, lagernivåer och ledtider i massavedsförsörjning.
Metoden som användes var objektorienterad händelsestyrd simulering i kombination med linjärprogrammering. Styrningslogiken som användes baserades på systemstatus och tog beslut om allokering av transportresurser genom justerad schemaläggning av tåg, anpassningar i biltransporternas totala kapacitet samt omstyrning av flöden mellan industrier. Två system användes, baserade på järnvägens struktur för norra respektive södra Sverige.
Autumn water sources for understory vegetation and fungi in a boreal forest : an evaluation using stable isotopes
Understory vegetation and fungi are regarded as important ecological drivers of processes like productivity and nutrient cycling in boreal forests. Whilst those processes are linked to soil water content, relatively little is known about the sources of soil water for these forest
components. During early autumn in boreal forests, temperature falls and large events of rain are frequent which may influence soil water availability. To better understand the autumn plant-soil-fungi water relationships in this ecosystem, I used stable isotopes techniques in this
study to examine the water sources for ericaceous shrubs and fungi in a Scots pine forest following a large, early autumn rain event. I hypothesize that ericaceous shrubs of two functional groups (evergreen vs.
Det krympande klassrummet : En studie av högstadielärares förutsättningar i ett reformerat skolsystem
Since the 1990?s the Swedish school system has undergone major and recurring structural reforms. Two of the most comprehensive changes has been the shift of primary schools as an integral part of the welfare state to the responsibility of the municipalities as well as the introduction of free school choice for the students. Through two months of participant observations and semi-structured interviews this thesis seeks to answer the question of how these reforms has come to effect the work of teachers in a medium sized public school in a small municipality in the outskirts of Stockholm. Earlier research has shown that public schools in socio-economically vulnerable areas are disadvantaged due to the reformation of the school system (Beach & Sernhede, 2011; Östh, Andersson, & Malmberg, 2013).
Monofilt eller multifilt suturmaterial : Vad är bäst för den nyblivna mamman?
SyfteSyftet med studien var att undersöka om det fanns skillnader mellan kvinnor som blivit suturerade med ett snabbabsorberande monofilt suturmaterial, Caprosyn® och ett multifilt suturmaterial, Polysorb® då det gällde kvinnans uppfattning om hur bristningen läkte åtta veckor postpartum.UrvalEtt konsekutivt randomiserat urval. Fyrahundratvå kvinnor som fått en bristning vid förlossningen randomiserades till att sutureras med antingen Caprosyn® eller Polysorb®. Den slutgiltiga svarsfrekvensen var 67 %, det största bortfallet var på förlossningsavdelningen.MetodEn experimentell kvantitativ studie. Två enkäter användes i studien, en som barnmorskan besvarade direkt efter förlossningen om bristningens art samt en till de medverkande kvinnorna åtta veckor postpartum.ResultatInga skillnader fanns mellan suturmaterialen då det gäller kvinnornas smärta i underlivet, obehag i underlivet, återupptagande av sexualliv, samlagssmärta, amning eller hur många kvinnor som sökt sjukvård samt varför de sökt sjukvård åtta veckor postpartum. Fler positiva kommentarer gavs av barnmorskorna om Polysorb® än om Caprosyn®.
Klinisk gradering av hästens luftvägsstatus : en jämförande studie av kliniska graderingsprotokoll samt deras relation till luftvägshälsa och neutrofilförekomst i BAL-vätska
Respiratory disease with airway inflammation as main characteristic is common in the horse. It is a syndrome that is not yet fully understood. The etiology, pathogenesis and classification into different disease states are subjects for discussion and under continuous revision. Despite a number of modern techniques, the diagnostic procedure is challenging. There is no test considered to be gold standard when diagnosing these diseases.
Konceptframtagning av testinstrument för vattendetektion baserad på MIP
Water is vital for all life on earth. But it can also be dangerous, even fatal, if it is polluted water. 60 percent of child mortality can directly be deduced to dirty water. Not only developing countries are affected, even in the western world epidemics are breaking out by partake or bathing in dirty/polluted water.MIP, Molecularly Imprinted Polymers, is a biosensor technology that can provide faster and more reliable response than the current methods of water analysis. It is also cheaper and due to that more samples can be taken and analyzed.
En ekonomisk utvärdering av framtida biobränslebaserade processkoncept inom energisektorn
The main purpose of this bachelor thesis is to create a product in the form of a database that can be used for cost estimates of equipment within bio refineries. Through interviews and literature searches the key components and their costs were identified. The database was constructed in Microsoft Excel with different tabs for different categories of components; these tabs are further divided into three parts: one part with costs, one part with calculations and an information part. Most of the part with costs contains the expenses found in scientific papers during the literature study, the calculating part converts different capacities according to user preferences and the currency to euro (?) from 2010 and the information part consists of references and information about what is included in the cost.The database is a good tool for making cost estimates for bio refineries.
Agricultural and forestry business owners? perceptions of banks
Over the course of the past the agricultural sector has been characterized by radical market changes. Changing market conditions have forced owners of agricultural and forestry businesses to make further investments. This increase in investments has led to a greater need for external capital, which has increased the relationship between banks and owners of agricultural and forestry businesses. The financial sector is characterized by strong rivalry, which forces banks to create strategic positions in the financial market. Since agricultural and forestry businesses are generally seen as secure customers by banks, due to high property and land values, the competition between banks with agricultural and forestry businesses as customers has amplified.

Boksamtal : En språkutvecklande metod för andraspråkstalare
The main purpose of this essay is to study how classroom interaction can take place in a class for Second Language Learners (SLL).1 I have applied a case study methodology on a linguistic method used by a Teacher in Swedish as Second Language working on a primary school situated in the Southern suburbs of Stockholm. The learning method is based on extensive reading of books which comprehend several learning techniques organized into a process that support the development of linguistic skills such as discussing in a group, writing, reading and thinking in a second language. The methodology applied is based on observations, on an interview with a Teacher in Swedish as Second Language and on a questionnaire answered by 11 students that participated on ?Boksamtal?.Based on a theoretical framework about socio cultural theories on learning and scaffolding,2 I attempt to integrate theory and practice to investigate how the Teacher succeed on applying effective methods for second language learning. Through the analyses of the data is also my intention to emphasize the advantages and disadvantages of such a method.
Tr?stadens dolda utrymmen: fasader i husens mellanrum som kulturhistoriskt k?llmaterial
This thesis explores the narrow spaces between closely built houses in the over 300-year-old wooden
town center of Mariestad, Sweden, and their potential as time capsules and sources of knowledge in
cultural-historical building investigations. By interpreting well-preserved carpentry work on a facade
in one of these spaces, the study aims to provide an example of how these preserved spaces can serve
as a source of knowledge and understanding of craftsmanship and the history of the place. The thesis
also addresses the municipality of Mariestad's work with cultural heritage, as well as maps out more of
these potentially interesting interstitial spaces. Old Swedish wooden towns possess a high degree of
uniqueness both nationally and internationally; nevertheless, they are subjected to relatively significant
threats of demolitions and substantial changes, often in the form of many smaller restorations or
changes over a long period of time.
The focus of the case study is a window from the 16th or 17th century and the facade's old, hand planed wooden cladding.
