Inventering och karakterisering av brännbart avfall i
Norrköpingsregionen
The purpose of this study has been to make an inventory of combustible waste in the region around Norrköping and to investigate the composition of domestic waste, industrial waste and two different types of sludge. The work was performed at the request of Norrköping Miljö & Energi, due to the planning of an incineration plant. The inventory of the waste was performed through inspection of environmental impact reports, from waste disposal plants in a number of local government areas in the region. The quantities were also compared to another inventory, carried out in a different way. The characterisation of the wastes was compared to the fuel specification determined by Norrköping Miljö & Energi.
Hur bedöms vallens avkastning?
Grassland is a great part of Swedish agriculture and there is a demand of what the grassland yield is in practice. To be able to control the economic of the milkproduction it is important for the farmer to know how big quantities of pasture there is to use during the year.The work is based on interviews of 22 farmers from southern part of Sweden. Their area of grassland fluctuate between 16 up to 360 hectares. The questionnaire content 32 questions.The most common way to weight the green plant material is to drive over a scale, and to measure the dry extract with your own gauge. It takes in average two minutes toweight one load of green plant material.
Konst, makt och politik i 1600-talets England : en analys av hur Charles I försök att använda konsten som medel för att stärka kungamakten speglades i Anthony van Dycks konst.
In this bachelor essay an attempt is done, to recreate a probable Bronze Age landscape on Gotland, with GIS as a tool. The landscape on Gotland is situated with many different monuments dated Bronze Age, such as cairns and stone ships. In creating of the maps, two possible shorelines contemporary with the Bronze Age have been calculated and marked on the maps. Furthermore, peat lands have been drawn upon the maps, by using the information from geological maps.A landscape variable have been compared between Bronze Age places and Early Iron Age houses; the soil type. On Bronze Age places gravel is the most common, while moraine marl is the most common on places with Early Iron Age houses.From a selection that were made, all Bronze Age places where within 3 km from the water, either the recreated shoreline or peat land.

Markanvändning och ekosystemtjänster i en gradient från borealt till alpint landskap ? Vilhelmina Model Forest
Begreppet ekosystemtjänster kan användas för att tydliggöra värdet av landskapets funktioner och därmed underlätta kommunikation mellan markanvändare då olika intressen konkurrerar. Emellertid finns det få studier som inkluderar en kvantitativ eller kvalitativ värdering av ekosystemtjänster på landskapsnivå. I detta arbete har markanvändning och ekosystemtjänster studerats i ett landskapsperspektiv, med Vilhelmina Model Forest (VMF) som studieområde. Den övergripande frågan i VMF är hur rennäring kan kombineras med andra markanvändningsintressen, huvudsakligen skogsbruk. Syftet med studien var att göra en kvantitativ värdering av markanvändningsintressen och ekosystemtjänster.
Klimatanpassning och lantbruket i Värmland : Klimatförändringarnas upplevda effekter på lantbruket och olika aktörers åsikter om klimatanpassning
Climate change is a global and slow process that affects humans all over the world. Climate adaption within agriculture is important to reduce the risks that agricultures are exposed to because of climate change. Through climate adaption you can improve the positive effects and take advantage of them optimally. How the climate change affects agricultures varies depending on regions and societies. The purposes of the study are to examine how different actors experience the impacts of climate change on the agriculture in Värmland.
Restaurerade ängs- och betesmarker : restaureringseffekten på växter och insekter
Semi-natural grasslands have a high biodiversity and host ecologically and economically valuable ecosystems and species. Restoration on these types of land is often done by removing trees and scrubs, mowing, grazing, changing the soil by removing nutrition or changing the structure of the ground. Another way of restoration is planting seeds of common grassland plants.
By comparing 18 scientific publications I investigated if the restoration was affecting the plants in a positive way and if the effect was similar for insects. By comparing the publications, time seemed to have an important effect on insects. They needed time to recolonize restored areas.
Livet mellan husen : ett utvecklingsförslag för Disagården
The open air museum of Disagården is situated in the Old Uppsala parish,
Uppsala municipality, are projected to portray a double row village, before
the land enclosure, on the Uppsala plain during the 1860s and 1870s.
Disagården operates under the County Museum of Uppland and serves as an
exhibit of Uppland's farming culture during the late 19th century. However, an
open-air museum is a complex institution where many interests are linked
together. Disagården aims to simultaneously portray an historical
environment while offering broad public appeal.
The Disagården open air museum was inaugurated in 1931 and consists of
relocated buildings that together form three farm complexes "Gränbygården",
"Skuttungegården" and "Bärbygården".
The thesis explores how the close surroundings of a typical farm in
Uppland looked during the 1860s and 1870s. This historical depiction has then
been applied to Disagården in a development suggestion creating a
foundation from which Disagården can structure the close cultivation of the
different farms. The basis of the development program has primarily been
compiled through archival and literary studies but also through on-site visits
and interviews.
How did the concept of open air museums start and what were the ideas
behind the concept? Which external influences affected the situating of
cultivations and buildings? Which crops and species were present on the
farms in Uppland during the specified time period? What was the relation of
the different structures to each other? Which organizations had influences on
the farmer's household of the Uppland plain? The thesis attempts to clarify
the answers to these questions.
The influences affecting on the farmer's household in Uppland were
probably numerous.
Värmeöverföring i bergvärmesystem : En numerisk analys av den ringformade koaxiala borrhålsvärmeväxlaren
The borehole heat exchangers of today suffer from poor thermal and hydrodynamic performance. The purpose of this thesis is to improve the performance of ground source heat pump systems and thermal energy storages by increasing the energy efficiency of the borehole heat exchangers. For this reason, the annular coaxial borehole heat exchanger (CBHE) has been analyzed. This type of heat exchanger is interesting in terms of both thermal and hydrodynamic performance. A model has been set up in the program Comsol Multiphysics in order to investigate the heat transfer characteristics along the borehole.
GRÖN FLAGG : Miljöarbete i förskolan
The aim with my work is to get a deeper knowledge about the preschool's views of environmental work. I also want to examine how the preschool teachers along with the children work with the project Green Flag in the preschool. I have used structured interview with two teachers in a preschool that works with Green Flag. Green Flag is an environment certification and is an evidence on that one works daily with a document aimed environmental work along with the children. I have found out that each year they work with different themes within Green Flag.
Arkeologisk landskapsanalys och prospektering av bebyggelselämningar och gravfält vid Alsike hage
This paper deals with archaeological prospecting for the purpose of finding a prehistoric settlement in Alsike hage, Alsike parish, Uppland. The methods being used are soil phosphate analysis, electromagnetic survey and settlement analysis. Two 20x20 meters areas have been prospected. As Alsike hage contains several late Iron Age burial fields, large splendid zones for settlement location, closeness to water as well as farmland there was a hope of locating remains of prehistoric settlement in the area. None of the prospected areas showed any distinct evidence of settlement remains.
Bogbladssår hos suggor : är höjden på tuber spina scapulae en riskfaktor för utveckling av bogbladssår?
Sow shoulder lesions are a common form of decubital ulcers in sows. The wounds are often bilateral and affect both loose housed and restrained sows. In most cases shoulder lesions develop after farrowing and heal after weaning. Sows that once have had decubital ulcera are however more proned to develop new wounds after the next farrowing. The problem is multifactorial and a number of risk factors have been described, including body condition, body size, parity, time spent lying down, flooring, moisture, breed, body temperature and some herd factors.
The aim of this study was to investigate whether the height of the tuber spina scapulae is a risk factor for the development of decubital ulcers.
Hussvamp : Skadeverkan och tänkbar ökning i Kronobergs län
Serpula lacrymans infestation has become an increasingly common problem, and is usually perceived as a tip of an iceberg.During the 21st century there has been a perceived increase of damage caused by serpula lacrymans, at AB Mats Fransson Saneringstjänst ? Anticimex in the county of Kronoberg. A similar increase has also been noted by employees at the offices in Kalmar, Karlstad, Piteå, Stockholm, Malmö, Söderhamn, Halmstad and Visby.The methods used to collect data for the project has been interviews with a number, for the project, relevant key persons, such as analysis engineers at Trygghansa and Anticimex, as well as personnel at the botanical institution at Gothenburg University and the Botaniska Analysgruppen in Gothenburg, further statistics from SMHI and analyses of reported instances of infestations have been used.The majority of the people interviewed believe that the increase is caused by renovations of old houses, higher precipitation during the summer months, as well as a moister climate and warmer winters. The latter can also be gleaned from statistics from SMHI concerning temperature, precipitation, and relative humidity.Analysed damage reports show that the most common cause for the infestation is ground moisture, even when combined wooden materials.Older houses that where built around 1900 are the ones most frequently infested with serpula lacrymans. The part of the building most frequently infested is the foundation, where cellars and suspended foundation are the most common types to be infested.
Fuktstudie om uteluftsventilerade vindar med beräkningsprogrammet Simple Cold Attic Model från Annex 55
Fuktskador på uteluftsventilerade vindar är ett ökat problem, i det mer miljömedvetna Sverige. Genom tjockare vindsbjälklagsisolering minskar både energiförlusten genom bjälklaget och uppvärmningsbehovet i huset, men hur många funderar på vad som händer med det förändrade klimatet på vinden och hur det kan påverka fuktförhållandena i utsatta delar av konstruktionen.Studier från Chalmers Tekniska Högskola har framställt ett fuktberäkningsprogram för uteluftsventilerade vindar vid namn Simple Cold Attic Model. Programmets funktion och potential har prövats i denna rapport genom en beräkningsanalys av en uteluftsventilerad vindskonstruktion. Försök till att förbättra fuktsäkerheten i konstruktionen har utförts och redovisas i rapporten. Studien har påvisat att den studerade konstruktionen inte är fuktsäker om den uppförs i Stockholmsområdet. Det visades även att aktiva val i konstruktionen kan förebygga fuktskador. Studien har påvisat vikten av inte beräkna med medelår för klimat och hur det påverkar beräkningsresultatet av mögeltillväxt.
Biologin hos svenska Lilioceris arter och åtgärder för att begränsa deras skadeverkningar :
Summary
The leaf beetles, Lilioceris lilii and L. merdigera have existed in Asia, Europe and in North Africa for a long time, but have become much more abundant the last twenty-five years. Even North America has been affected during the last years.
The purpose of this investigation of Lilioceris species in Sweden, is to give advice to gardeners, which type of control measures is the most effective in order to restrict their damage to lilies.
Lilioceris species overwinter normally as pupae in the soil under the host or close by.
Literature and contact with advisors have described the life cycle and spreading of Lilioceris. Under favourable conditions these leaf beetles have two generations/year in the south of Sweden. Both the adults and the larva eat the foliage, and by strong attacks even flowers can be eaten and only the stem is remaining.
My own observations include different treatments of both lily foliage and of the leaf beetle.
