Smarta lokala energisystem, Vision-Teknik-Tillämpning
The energy sector is facing an impending paradigm shift. Today?s technology enables the end-user to generate their own energy locally at home. Furthermore, recently developed storage technologies make it possible to balance energy demand with stored energy and integrate district heating with the local power grid. This means that in the future heat and electric power will interact and energy flows is converted over energy boundaries.
Utveckling i Ammerån : att skapa ett hållbart fiske med hög kvalitet
Ammerån which is a small forest river in eastern Jämtland is a well-known river that has been a popular fishing river for a long time. The actual Ammerån begins downstream the lake Solbergsvattnet at Hammerdal and flows into the Indalsälven 10 km upstream Hammarstrand. The river environment switches between forests with wilderness feeling and open agricultural land. The entire Ammerån is today a nature reserve and protected from hydropower development. Fishing in Ammerån has mainly been focused on trout and grayling, and is so even today.
Habitat preference and foraging behaviour in adult red-tailed monkeys (Cercopithecus ascanius)
The red-tailed monkey (Cercopithecus ascanius) is a small, alert and active animal inhabiting forests with dense vegetation and as such hard to observe in its natural habitat. The principal aim of this study was to scrutinize whether the methods, previously used in a behavioural study of the blue monkey (Cercopithecus mitis) can be applied in studies of the red-tailed monkey?s behaviour as well. Additionally, habitat preference and foraging behaviour of the red-tailed monkey were examined. The study was carried out between the 16th and the 22nd of March 2009 in the Sabaringo forest, located on the western border of the Masai Mara National Reserve.
Sköra äldre patienters upplevelse av vistelsen på akutmottagningen
Background: The number of older people is increasing in Sweden. The elderly patient often requires a more complex type of care, than younger patients. The concept of frailty is often used to describe individuals who have a high biological age and a decreased physiologic reserve which could be associated with acute illness and an increased vulnerability. Emergency medical care today is not suitable for elderly patients and adaptions for these elderly patients and the demands this places on the health care is necessary. Mölndal Hospital emergency department has around 42 000 visitors per year, many of the clients have a high age.
Kommunal resultatutjämningsreserv : Motiven till att införa eller inte införa en konjunkturreserv i redovisningen
Mot bakgrund av de senaste decenniernas konjunktursvängningar i världsekonomin konstaterades det i Sverige att det fanns ett behov av att kunna möta dessa svängningar. Detta resulterade i den lagändring av Kommunallagen och Lagen om kommunal redovisning som erbjöd kommuner möjligheten till att införa en resultatutjämningsreserv i redovisningen. Denna resultatutjämningsreserv utgör ett periodiseringsverktyg där medel kan reserveras i goda tider för att sedan utnyttjas i sämre. Lagändringen är frivillig att anamma och har skapat en viss flexibilitet i kommunernas redovisning. Då kommuner har olika förutsättningar kan detta leda till att motiven till ställningstagandet kring ett införande av en resultatutjämningsreserv skiljer sig mellan kommuner.
Natura 2000-områden: rättsverkningar i jämförelse med vanliga naturreservat
Syftet med uppsatsen, att utreda de skillnader i rättsverkningar som finns mellan Natura 2000-områden och vanliga naturreservat,har jag uppnått genom att använda mig av traditionell juridisk metod. Genom att jämföra lagtextformuleringar, förarbeten och bakgrund till bestämmelserna om de två områdesskydden har jag funnit att reglerna om Natura 2000-områden har en betydligt större räckvidd än bestämmelserna för vanliga naturreservat. Allehanda verksamheter och åtgärder omfattas av den särskilda tillståndprövning som gäller för ingrepp i Natura 2000-områden, medan vanliga naturreservat har begränsad räckvidd till de ingrepp som stadgas i reservatsföreskrifterna. Jag har även funnit skillnader när det gäller inrättandet och upphävandet av områdesskydd, och resultatet är att EU-kommissionen utövar en stark kontroll vad gäller Natura 2000-områden. Kommissionen kan tvinga medlemsstaterna att inrätta särskilt skyddat område, och om medlemsstaten vill upphäva skyddet måste samråd ske med kommissionen.
Framtagning av en förebyggande åtgärd mot kriminalitet vid lastbilstransporter
Boberg at Scania CV AB. The purpose was to investigate the technical and customer oriented possibilities for the development of a transport security measure against cargo crime, which is a growing problem in Europe. The main goal was to develop a concept that is possible to implement in the Scania CV AB Fleet Management System. Another goal was to develop a security model that will be used as a tool during Scania CV AB?s future development projects of transport security concepts.The work was divided into three main parts: a background study, handling cargo crime, transport security Scania CV AB trucks and market analysis, a stakeholder investigation including a questionnaire and interviews, and a concept development session.
Allanblackia stuhlmannii ? a tree under current domestication: what are the soil requirements?
Allanblackia is a genus of trees that grows in the rainforests of West, Central and Eastern Africa. Its big fruits contain seeds very rich in oil which has been used by
local communities for cooking and making soaps. The native stands are threatened by overexploitation and the demand for the oil is much greater than the supply.
Domestication programs, aiming at introducing the trees to small holder agroforestry systems, have been started for some of the species. The main aim of this study was to investigate the soil requirements of Allanblackia
stuhlmannii in terms of chemical and physical parameters, as revealed by the soil conditions in native stands. Another aim was to see if these varied along an altitudinal transect.
Vart är naturen i skärgården på väg? : skogshistoria på Ängsön-Marskär i Stockholms södra skärgård
The following thesis is a study of the forest history on the island of Ängsön-Marskär concentrating on the last three hundred years. The island is located in the administrative province of Stockholm, the local community of Haninge and it is situated approximately seven kilometres east of the island Ornö in the south of the Stockholm archipelago. The questions this thesis attempts to answer are: How where the natural resources on Ängsön-Marskär used through the centuries? How has the state of the forests developed since the 16th century? How will the nature develop onwards? The thesis is based on archival sources for Ängsön-Marskär and the surrounding areas. A field study was conducted where the entire island was investigated using an objective forest inventory method.
The first map material existing over Ängsön-Marskär is from the year 1711.
Dagvatten i Märsta : förslag till anläggning för ekologisk hantering samt metodöversikt
Stormwater in urban areas has been treated as a problem for a long
time. The large proportion of impermeable surfaces inhibits the water
from infiltrating in the ground to the same extent that it does in nature.
This causes intensive surface flow during rain, which in turn causes
inconveniences such as decreased accessability, floods and increased risk
of desease spreading. Drainage through pipes is the traditional and usually
functional metod for storm water disposal. That is as long as water flows
are moderate. But precipitation varies naturally in amount and intensity
and additional impermeable surfaces make some pipes insufficient for
heavy or lasting precipitation.
Analys av spänningsstabilitetsberäkningar i det svenska elsystemet
Numerical simulations play a vital role in both static and dynamic stability assessment of electric power systems and the foreseeing of voltage collapse. Simulations performed by Svenska Kraftnät(SvK) are mainly done in the specialized voltage collapse predicting software tool, SPICA and the more all?purpose software tool, ARISTO.The grid operators at SvK use SPICA to predict the maximum transfer limit at specified sections (in this report the section in concerns is the southern part of Sweden i.e. interface1 4). SPICA is mainly used as an online application by using actual states from the grid, these states update every quarter of an hour.This thesis is a continuation of the master thesis SPICA ? ARISTO JÄMFÖRELSE by Jakob Katzman and Johan Fält.
Landvinning : scenarier för efterbehandling och gestaltning av Aitikgruvan, Gällivare
Open pit mining creates huge amounts of tailings and waste rock deposits. Due to it's content of sulphide minerals, predominantly pyrite (FeS2), there is a risk of oxidation and formation of acid water containing heavy metals, known as Acid Rock Drainage (ARD). To prevent the process of oxidation, the tailings and waste rock have to be reclaimed. The most commonly used methods of reclamation are a coverage of water or soil.
Mining also results in a large-scale interference in the landscape that will make an eternal change of its appearance.
Potentiell fosforfrigörelse från sedimentet i Bornsjön, sydvästra Stockholm : The potential leakage of phosphorus from sediment in Lake Bornsjön, south western Stockholm
Lake Bornsjön is situated 30 km southwest of Stockholm in a rift valley lake and consist three basins outstretched in northwest-southeast direction. The surface area is 6,7 km2 with a maximum depth of 18,3 meters, a mean depth of 9,8 meters and a retention time of the water of 6,5 years. The drainage area is 42 km2 and consists mainly of arable land (ca 1000 ha) and productive forestry land (2500 ha), but in the drainage area there are also restored and fairly newly constructed wetlands.Today the Stockholm area receives its drinking water from Lake Mälaren, but if there would be any pollution of this source, Lake Bornsjön would act as the water source. The area surrounding the lake was bought already in 1899 by Stockholm Stad for protection of the lake and was taken over 1993 by Stockholm Vatten AB. It has been a water protection area from 1988 and it was also accepted as a nature reserve in 1995.
Kan risken för spontan contortaföryngring elimineras genom hyggesbränning? :
Sweden has almost 600 000 hectares planted with lodgepole pine, and large areas are soon ready to be clear-felled. The provenances that have been planted are producing high level of permanently closed, so called serotinous, cones. In their natural setting, the Canadian boreal forest, these cones are opened mainly after crown fires when the heat make the resin between the cone scales melt, which releases the seeds. This is viewed as an adaption to the fire regimes that prevail over the natural distribution area of lodgepole pine. Because of the short flame-exposure that occurs in a crown fire, the seeds can survive.
