Vattenkvalitén i Fredstorpsbäcken - dikad bäck på fastigheten Rämningstorp i Skara kommun :
The estate of Rämningstorp in the region of Västergötland in southern Sweden is administered by the holding trust company Skogssällskapet i Skövde. In 1999 measures were taken by Skogssällskapet to drain the stream Fredstorpsbäcken as a means to increase the forest productivity of the surrounding lands, which are situated on the estate of Rämningstorp. Almost immediately after the drainage, the streamwater turned turbid and a landowner downstream reported the issue to the county administrative board of the region.
The aim of this thesis was firstly to analyse the suspended matter that appeared during summer/autumn and secondly to explain why it came to be. Initial hypotheses for the explanation to the greyish turbid water were that it was either 1) a chemical/biochemical precipitate, or 2) an bacterial/algal blooming.
Common misconceptions about everyday astronomy-related phenomena among students in the 9th grade
Students of all ages host a wide variety of scientifically inaccurate ideas and conceptions about everyday astronomical phenomena, such as the seasons, the moon phases, and gravity. The field of Astronomy Education Research has over the last decade experienced an accelerating growth, although the majority of studies have been conducted in the USA. In this work, the 9th grade students of a typical Swedish school were surveyed by means of a questionnaire in order to probe their conceptual understanding of several key concepts in astronomy. In the end, the number of respondents amassed to a total of 90. The results were analyzed with a constructivist approach in light of conceptual change theory and phenomenological primitives.
Nationellt miljökvalitetsmål på lokal nivå : en fallstudie av arbetet med miljökvalitetsmålet Ett rikt odlingslandskap i Lunds kommun
Several thousand years of human impact on the landscape in the form of cultivation is the
reason to many nature- and culture values in the agricultural landscape today. Intensification
and rationalization has led to vast monocultures and has forced many farms to close down.
These trends have increased in the last years and constitute great threats to the values of the
cultivation landscape. The purpose with the environmental objective A varied agricultural
landscape is to protect these values.
The environmental action plan of the municipality of Lund (LundaEko) 2006-2012 is built on the
16 national environmental objectives. The purpose with this paper is to put together material that
the municipality of Lund can use in their work with modifying the local intermediate goals for
the environmental objective A varied cultural landscape. The overall issue for this paper is
?What has happened with the state of the cultivation landscape in the municipality of Lund since
LundaEko was approved in 2006?? The paper seeks to portrait the current conditions of the
following fields: meadows and pastures, organic farming, exploitation threats to agricultural
land, landscape elements with cultural values and species that are threatened.
Kastanjemalen Cameraria ohridella : livscykel och utbredning i Sverige 2006
Cameraria ohridella, the chest-nut leaf miner, is a new pest in Sweden. These moths make leaf mines on chest-nut trees, preferably on Aesculus hippocastanum, which results in brown blotches on the foliage and early loss of leaves. Since the first observation in Macedonia in 1985 it has spread rapidly through Europe. The moth arrived in Sweden in 2003 when it was observed in Malmö and surrounding areas.
In this paper a literature study describes the morphology and life cycle of the chest-nut leaf miner. Further more a test with pheromone traps examining the number of generations in Sweden is shown.
Evidens för traktions- och träningsbehandling vid lumbalt diskbråck: Litteraturstudie
Patienter med diskbråck i ländryggen är en vanlig patientkategori som behandlas av fysioterapeuter. Symtomgivande diskbråck kan vara fysiskt och psykiskt påfrestande för patienter. Initialt behandlas de flesta konservativt med bland annat traktion och träning. Verkningsmekanism för dessa behandligar, effekt på patientens symptom och evidensgrad är oklara. Det är viktigt att sammanställa och värdera behandlingsmetoder som används av fysioterapeuter i klinisk praxis.Syftet med denna litteraturöversikt var att granska det vetenskapliga underlaget för traktions- och träningsbehandlingars effektivitet på smärta, funktion och diskbråckets storlek vid ländryggsdiskbråck.Litteratursökningarna genomfördes i följande databaser: PubMed, Ebsco host, SweMed, Cochrane Collaboration och Scopus.
Ingen Lag - Straff? Straffansvar och befogenheter för svensk militär personal i internationella insatser ur ett rättstillämparperspektiv.
INGEN LAG ? STRAFF? ABSTRACTThe thesis deals with a gap in the Swedish legislation concerning the criminal responsibility under which military personnel act in international peace operations. According to international treaties called Status of Forces Agreements, military personnel operating abroad within the territory of other states are exempted from the criminal law of the host states. In return, their home states apply its national criminal law upon the personnel instead. Thus, Swedish criminal law is applied in relation to actions taken by Swedish military forces in international operations.
Franska dotterbolags etableringar på den svenska marknaden.
Today?s globalisation has opened up borders between countries as can especially be seen with the opening of the European Union. This has increased possibilities of communication and transportation, which has provided companies with greater expansion opportunities throughout the world. However, difficulties may occur when companies choose to establish abroad, for instance when French companies establish in Sweden through subsidiaries, the lack of knowledge and understanding, when it comes to the business culture, customs, and values within the host country, as well as the culture and the structure within the company, may contribute to misunderstandings and inability to work in an amalgamated manner. These barriers are a cause of unsuccessful penetration within foreign markets.
Animal Assisted Therapy som fysioterapeutisk behandling för barn och ungdomar inom habilitering och rehabilitering: En litteraturöversikt
Behandling eller terapi ihop med hund kan hjälpa barnet att utveckla och förbättra dess finmotoriska färdigheter. Hunden kan även medverka och underlätta vid utbildning och dessutom öka barnet fysiska, mentala och emotionella status. En hunds utryck av sympati och omtanke kan vara första gången barnet upplever att de blir hörda och känner sig viktiga och på så sätt ger dem tröst. Syftet med denna studie var att skapa en översikt över den vetenskapliga grund som finns för AAT med hund inom fysioterapeutisk behandling av barn inom habilitering och rehabilitering. Studien är en litteraturöversikt.
Makten över ordet En kvantitativ undersökning om genusrepresentationen i SVTs Debatt
Authors: Daniel Kirby & Émelie Vangen LindgrenTitle: Controlling the WordLevel: Bachelor of JournalismLocation: University of GothenburgLanguage: SwedishNumber of pages: 29The largest arena for public debate in Sweden is the television show Debatt, airing every week on SVT: Sweden?s public service network. Every episode has an audience at around 500.000 viewers. Because the channel is under the rules of the public service agreement, strict rules of diversity are applied.The purpose of this study is to examine the gender representation in Debatt; to investigate how men and women behave in the context of the televised debate and to see if the programme has managed to reflect an equal representation of the voices of men and women.We did this by performing a quantitative content analysis of four different episodes of Debatt, with 4 different hosts ? two women hosts and two men.
Vivlar på prydnadsbuskar - nya arter eller förändringar i födopreferenser?
During the last couple of years leaf-edge-cuts, typical to Otiorhynchus wingless-weevils, have been discovered on ornamental shrubs, especially Syringa vulgaris lilac and Ligustrum vulgare privet. These plant species have not earlier been attacked by wingless-weevils and because of that, the aim of this study is to see if new species of weevils have been established in Sweden or if the domestic weevils have changed their food preferences. This work also includes a literature study of known weevil species in Sweden and their host plants, and of wingless-weevil species in Europe that could be invasive here. Locations, where damage to previously named plants has been reported, have been examined. The extension and appearances of the damages have been documented in order to study if different weevil species make different types of edge-cuts.
En systemlösning för en framtida fjärrvärmeutbyggnad i Täby : ur Fortum Värmes perspektiv
At the moment in central Täby there are small district heating network operated by
Fortum Heat. The distribution network has an annual heat demand of about 70
GWh, which is supported by the network's two plants, Galten and Farmen.
Täby as a region is rapidly growing and there are grand plans to develop the area.
Estimated market potential for a future district heating expansion in Täby is very
high and as early as in 2007 Täby decided to invest in a large-scale expansion. In
autumn 2009 Täby did a procurement process, known as the ?Täby initiative?, to
find a partner that could implement those expansion plans. To secure a cheap basic
production the partner also need to build a power plant at Hagby recycling center.
Despite high interest during initial state of the process, only one procurement offer
were received and Täby suspended the contract in March the following year.
Artrika vägkanter - hur påverkas de av slåtter och underhållsdikning?
ABSTRACT
This study is an exam work at the Department of Ecology at the Swedish Agricultural University, Ultuna, Uppsala. The field work was performed in the counties of Uppsala and Västmanland.
Grassland areas, exposed to annual mowing, are known to host a variety of rare and red-listed vascular species. The area of these grassland are, however, decreasing in the landscape due to modern farming. The fact that roadside verges maintain regular mowing has proven to be a successful concept for many rare vascular plant species in this habitat.
Vascular plants along roadside verges at the State road network were inventoried due to a government mandate during 1995 and 1996. As a result ?Species rich roadsides? were pointed out.
Förekomst av Chlamydia/Chlamydophila spp hos gris med och utan konjunktivit.
ABSTRACTChlamydia and Chlamydophila are species of a family of bacteria (Chlamydiaceae) that cause a range of diseases, including conjunctivitis, in a variety of animals including pigs and humans. Some species cause zoonotic disease. This study examined the occurrence of Chlamydiaceae in samples taken from the lower eyelid conjunctiva in pigs with and without conjunctivitis. The study was initiated based on a herd investigation aimed to examine the experienced increase of conjunctivitis in some finisher herds. This study was conducted as a case-control study, by collecting samples from 62 case pigs (16-26 weeks old) and an equal number of controls, from three herds in Uppland, Sweden.
Freshwater pearl mussel as indicators of Swedish streams - a comparison between freshwater pearl mussel and biological quality elements
The freshwater pearl mussel (Margaritifera margaritifera) is a large freshwater mussel. Because of its sensitivity to human impact, such as eutrophication, acidification and alterations of hydromorphology, the species is considered as a robust indicator of stream water quality and biodiversity. Moreover, due to the species complex life cycle, including a larval stage on the gills of salmon and trout, and sensitivity of early life stages, regeneration is often used as an indicator. The freshwater pearl mussel is also used in the expert judgement of status classification of benthic invertebrates according to the European Water Framework Directive.
The purpose of this study was to gain a deeper understanding of the freshwater pearl mussel as an indicator for Swedish streams. It was made with two types of
association analyses.
Habitat preferences and reproductive success forthe threatened longhorn beetle Plagionotusdetritus
Plagionotus detritus is a threatend longhorn beetle that only exists at one site in Sweden. It is saproxylic and depending on recently dead coarse oak wood for its larval development. Trees at Djurgården, Stockholm that have been colonized by Plagionotus detritus has been studied to find out the habitat preferences of the species and to see what affects the density of beetles in a tree. The bark of some trees and wood from the breeding project at Nordens Ark has also been studied to find out what affects the species reproductive success. The reproductive success was measured in two ways, the larval mortality and the size of the hatching holes.
