Det enskilda trädet som meningsbärare : erfarenheter av två trädplanteringsprojekt i Helsingborg
Individual trees can act as carriers of meaning. When a person attributes deep meanings to a specific tree, a relationship between the person and the tree is created. To avoid conflicts between users and planners, increased awareness is required of how important individual trees may be to a person. The objective of this study was to elucidate persons? relationships with individual urban trees.
Framtagandet av gestaltningsskiss i sjukhusmiljö med sten och stenpartiväxter som utgångsmaterial
Enligt forskning har riktig natur och bilder av natur en avstressande effekt på människor i sjukhusmiljö. Stenpartier byggs ofta för att simulera naturliga förhållanden och kan upplevas som en tredimensionell landskapsmålning som förändras med årstidens växlingar.Syftet med denna studie är att komma fram till en gestaltningsskiss med hjälp av sten och stenpartiväxter. Gestaltningen tänkta plats är utanför Gävle sjukhus. Fokus har lagts på stenpartiets uppbyggnad, växternas krav och anpassningen till sjukhusmiljön.För att ta reda på ett stenpartis uppbyggnad och stenpartiväxters krav på växtmiljö har både en litteraturstudie och platsbesök med intervjuer gjorts. Litteraturen är sökt via LIBRIS.
En inventering av säregna trädformer funna i Sverige
In Sweden and in Scandinavia the amount of tree species are rather few. However many different forms of trees arise due to mutations and gives rare appearances like cut-leaved and hanging forms. In some cases these trees are interesting as cultivars and a few of them have become popular garden trees. The knowledge of the original trees and early propagation is meagre.In this study a selected group of trees were found through search of literature. Eight tree forms were chosen and investigated in situ.
Spridning av bekämpningsmedel i banvall : Modellutveckling och känslighetsanalys
The stability of railway embankment is essential for safe transport. In order to ensure safe transport, water should be allowed to freely drain. Furthermore, as the engine driver has to be able to see signs, and people working on the embankment are supposed to easily see flaws on the rails to ensure safety for the passing trains, Plants should not be allowed to grow on the embankment. In Sweden there are 12 000 kilometers of railway tracks and 25?30 % of them are treated for weed control every year.
Bildandet av naturreservat : uppföljning och klimatanpassning
AbstractWe are facing a century of rapid change in climate, with significant challenges in managing the impact of changes in living conditions for Plants and animals. We can already see the responses of species through changes in phenology and spatial distribution, which may change ecosystem structure and function, with subsequent effect on ecosystem services and biological diversity. In Sweden, between 2005 and 2010, the red-listed species has increased by 13 % and similar trends can be seen across the world, making it difficult to attain national and international environmental objectives of preserving biodiversity. One way to reduce the loss of biodiversity is to protect nature from exploitation by allocating valuable areas as nature reserves, but climate change affects protected areas just as much as other landscapes and therefore requires elaborate systems of protection to facilitate species' survival. The paper has examined how the decisions and management plans for nature reserves in Sweden have been followed-up and whether they are climate adapted or not by examining 30 nature reserves, classified as newly formed (2012), recently revised (2009-2011) and older (1977-2007) reserves, and assessed what is in the decisions and management plans for follow-up, revision, long-term goals and documentation.
The black-and-white colobus monkeys (Colobus angolensis palliatus) of Diani forest, Kenya : behavioural responses to habitat fragmentation
The loss of habitat is one of the greatest threats to global biodiversity today. Consequences to a species inhabiting fragmented habitats include: group size changes, altered diets and altered foraging behaviours.
In my study I observed Colobus anlgolensis palliatus troops living in the forests of Diani, a highly developed area on the Kenyan coast. I looked for differences in behaviours between three troops inhabiting pristine forest patches and three troops inhabiting highly degraded forest areas. I used focal animal sampling with instantaneous sample points.
Hägn i skogsbruket :
This survey was made during the autumn of 2002 and the beginning of 2003, on commission
from the National Board of Forestry. The purpose with the survey was to gather experience
and knowledge in the organisation about fencing and this was made through interviews. The
ambition was also to get knowledge from people outside the organisation that have great
experience of forestry and fencing.
The interviews were based on questions that have been composed by the author with help
from the supervisors. The questions were the same to both the personal from the National
Board of Forestry and to the foresters. Interviews were also made with private landowners, gamekeepers, game researcher, the County Administrative Board, the National Road Administration, pole and net retailers and contractors.
The target group for this work is the National Board of Forestry to be forwarded to persons interested in forestry with the ambition to spread knowledge about how to prevent damage on the forest by browsing animals.
The deer populations are big in the south of Sweden and growing populations have increased the damage on plantations of broadleaves of the most species.
Kvickrotens reaktion på klippning och konkurrens i rajgräs- och vitklöverbestånd :
Couch grass (Elymus repens (L.) Gould) is a severe weed in Sweden, and since both the use of herbicides and cultivation should be decreased, it will become increasingly problematic to control couch. The present work is meant to, by literature studies and an experiment, give some answers to the question if cutting and competition can depress the growth of couch. The experiment was carried out in the growing season 2001 at Ultuna, Uppsala, in plastic boxes. The design was three-factorial randomised complete blocks. The factors were plant combination, nitrogen level and cutting strategy.
Avsättningsmöjligheter för slaggrus från avfallsförbränning vid Åmotfors Energi
The incineration of waste is steadily increasing in Sweden and so is the production ofashes. The bottom ash has for many years been used as construction material inlandfills. Now many of the nation's landfills are closed and there is a great need to findanother beneficial use for the ash. Bottom ash is a gravel-like material and with itsmaterial properties it can replace natural gravel in parts of roads and surfaceconstructions. Today this use is only approved within landfill areas where leachate iscollected and checked.
Kundnöjdhet och produktutveckling av gravskötsel
Små skyltar, ofta i plåt med texten ?Vårdas av kyrkogårdsförvaltningen? finns på var ochvarannan kyrkogård runt om i landet. De visar att gravrättsinnehavaren till denna gravplatsvalt att betala för att få hjälp med skötseln. Denna studie syftar till att finna faktorer till enförståelse för vad det är som gör dessa kunder nöjda och hur tjänsten gravskötsel ska kunnautvecklas i framtiden.Undersökningen består av personliga intervjuer med personal vid kyrkogårdsförvaltningen iLandskrona och Malmö och en säljare vid Mäster Grön, en genomgång av sexkyrkogårdsförvaltningars hemsidor samt telefonintervjuer med 14 gravrättsinnehavare.Resultatet visar att graven ska vara välskött, de gravrättsinnehavare som mötts av ogräs är intenöjda med tjänsten. Personalens bemötande betyder också en del för hur nöjda kunderna ärliksom att majoriteten anser att priset är rimligt för tjänsten.Intresset för utvecklingen av gravskötsel och dess miljöpåverkan verkar mest ligga hospersonalen på kyrkogårdsförvaltningen och leverantörer av växter.
Kompostering av köksavfall och användning av kompost i köksträdgård i Chazuta, Peru : jordförbättring och/eller lösning på ett avfallsproblem?
All over the world the waste from human society is causing problems. In developing countries, large cities are polluted through huge amounts of wastes and people are forced to live very close to open deposits. Lima, capital of Peru, is no exception. The countryside in Peru has also a great challenge to face concerning the waste issue. Children and adults suffer from infectious diseases and contamination of the nature occurs as well.
One solution to handle organic waste is to compost, which means a controlled decomposition
of organic waste under aerobic conditions at certain temperatures.
Kväve i Östra Mälaren : hur kunskap förvaltas och används i tillståndsprocesser
The nitrogen cycle in freshwater bodies is complex and consists of many separate processes affected by a number of important factors for example oxygen concentration in the water, temperature and circulation. Knowledge of the different components of the nitrogen cycle exists; however, a complete and comprehensive picture is difficult conceptually as well as theoretically. The available literature illustrates that the research on nitrogen and the related freshwater processes is still associated with high uncertainty of how much of the supplied nitrogen from the catchment is transported with the water versus and how much is lost due to denitrification, sedimentation or uptake by Plants. This report is an interdisciplinary survey of Nitrogen discharge permitting. The research focuses in particular on the decision-making process, the levels of scientific standard and the administrative framework.Application for Nitrogen discharge permits are decided by the Environmental Court with council from their own experts as well as relevant government authorities and organisations.
Handen bakom Vegeholms engelska park - en studie av parken och dess uppkomst
A boom in horticulture characterized the 18th century in Sweden and Skåne. Parks and gardens were gradually built out to become, at the end of the 18th century, large and comfortable facilities which responded to European parks. During the late 1700s the new fashion came to Sweden. In Sweden it was named ?the English style? which directly refers to the English expression ?Romantic style?.
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.
