Entréträdgårdar - rumslighet, gestaltningselement, uttryck och sociala aspekter :
The BA thesis Front Yard Gardens ? spatiality, design elements, expression and social aspects is a summary of the entrance and front yard garden phenomenon ? where the entrance is the set design and the designer is the director. The thesis touches the social context of which entrances have been and still are shaped. The various appearance of the entrance and front yard gardens throughout the history, starting with the first entrance by the edge of the wood and coming up to the front yard gardens of today, is described. It touches the present day through an analysis of some entrances and front yard gardens of modern residential areas.
Mineraliska material som reaktiva filter för avskiljning av tungmetaller från dagvatten
Highly polluted urban storm water from e.g. highways can contain large amounts of heavy metals that may cause harm if they are discharged into recipients. To remove the heavy metals a possible low-cost method that does not require much maintenance, could be the use of reactive filters with filter materials consisting of industrial residues or other cheap mineral based materials. Dissolved metal ions are removed by reactive filters through the processes of ions binding to active sites on the surface of the filter materials, or by formation of insoluble precipitates.The ability of CaO-treated granulated blast-furnace slag, iron oxide coated sand, olivine and nepheline to remove seven heavy metals (Cr, Cd, Cu, Ni, Zn, Pb and Hg) from urban storm water was studied. Initially batch experiments were performed where the effect of pH, dissolved organic carbon (DOC) and dissolved ions on the adsorption efficiency was studied.
Bestämning av dagvattenflöden i Knivstaåns avrinningsområde
The purpose of the thesis was to map the hydraulic load on the Knivsta river from stormwater runoff, and build a platform for further studies of pollution loads on the rivers ecosystems. New residential areas are planned to be built in Knivsta municipality and it will have an impact on stormwater flows to Knivsta river. To examine the impact this will have, simulations were made in the area as it stands today and after expansion work. The work includes calculation of flows from the populated areas but also from the catchment area around it consisting of woodlands and fields. Because of expected climatic changes which may affect rainfall, the simulations have been performed with different return periods for rainfall data.
Oreglerad=Fri? En studie om Läkarkliniken
The discrepancy in the rights for healthcare between undocumented migrants and the citizen in Sweden is a prerequisite for the existence of Läkarkliniken. Because of the chosen patient group the clinic stands outside the regulations from the National Board of Health and Welfare. The aim of this study was, from an institutional perspective, to investigate how such a unique player is designed and where the influences to the design origin from. The task was conducted thorough a qualitative case study with base in depth interviews. High levels of isomorphism were observed between Läkarkliniken and the general healthcare, however differences were seen as well.
Hybridlandskap : nya möjligheter för offentliga platser i staden
This project explores how artificial landscapes as parks and squares above ground can save space by using the vertical voids in urban environments and how they can create spatial and social as well as ecological qualities and connections.
Hybrid landscapes are a phenomenon of current interest within the field of architecture and urbanism. Architecture as surface, where facades and roofs become possible to tread, is a relatively recent occurence that has over the past few years become an increasingly common sight in architectural magazines and on international architecture exhibitions. Many of my selected reference projects have often been associated with sensational contemporary design trends generated by advanced computer software. But the phenomenon is also a result of other different currents of change that exist within today?s society, such as densified cities with a lack of open space, which is also expressed in architecture.
Svensk prickskytt i urban miljö : Förändring, utveckling och behov
Dagens konflikter utspelar sig mestadels i helt eller delvis bebyggd miljö och vikten av en uppdaterad och väl fungerande prickskytteförmåga är därför central. Detta till trots, återfinns stora brister i den svenska prickskytteutbildningen vad avser just den urbana miljön. Denna uppsats syftar till att dels bidra med nya infallsvinklar samt ge ett användbart arbetsunderlag för Försvarsmaktens vidare utveckling i ämnet. Genom att komma på det klara med hur prickskyttar utbildas och används i Sverige idag och jämföra detta med utländska modeller och andra länders goda och sämre erfarenheter, vill jag ge förslag på hur den svenska prickskytteutbildningen skulle kunna utvecklas. För att ge uppdaterad information har jag begränsat min efterforskning genom att mina studier av andra länders prickskytteerfarenheter avser det senaste decenniets förehavanden, snarare än utvalda länders specifika tillvägagångssätt.
Impact of Eucalyptus plantations on pasture land on soil properties and carbon sequestration in Brazil
Soil organic carbon (SOC) stocks and fluxes in forest ecosystems are influenced by natural and human disturbances. In the tropical regions the highest impacts on disturbance in forest C cycles are related to human activities such as conversion of natural lands to cropland and pasture areas and to forest plantations. The disturbances in the forest C cycles will release CO2 emissions to the atmosphere triggering global warming. In this study the focus was set in subtropical soils in Brazil, south extreme region of Bahia. The aim of the study was to investigate whether reforestation of Eucalyptus plantations under former pasture areas will help mitigate climate change through carbon sequestration.
Metod för användning av Geografiska Informations System vid långsiktig vägplanering : en studie genomförd på Sveaskogs marker i Norrbotten
The forest industry is one of the most important industry branches in Sweden. Since the demand of high precision wood deliveries has increased, the demand on a well constructed forest road net also has increased. A good road net gives the wood-supplier competition advantages and also increases its service level towards its customers, lumber-mills and pulp-mills. In some parts of Norrbotten, the road net is still insufficient and not yet built out enough, and that is why it is important to know how to act and where to improve the road net in these areas.
The purpose of this thesis was to create a work-model for long term road planning in areas with no road net or a not yet complete road net. The model has been created in an ArcGis environment, where a long chain of tools has been tied together with the program ?Model builder?.
Utformning av lager : Modell för utformning av lagerfunktion med hänsyn till arbetsmiljö & säkerhet
Companies worldwide strive to reduce costs and capital tied up in stock. At the same time, the need for short delivery times requires efficient logistic flows. In order to meet customer demands an efficient warehouse activity is required.The purpose of this study is to develop a model for designing a warehouse system regarding to working environment and safety. The model is primarily designed and based on literature reviews of scientific articles and books, own knowledge and the authors previous work experience in the industry.The thesis has been done at Sandvik AB, the department Precision strip in Sandviken. Sandvik is a high-technology engineering group with advanced products and a world-leading positions within selected areas.
En ficka full av frihet; hur användningen av pocket parks kan verka restorativt på människor i urbana miljöer
Ett livslångt intresse för psykologi och landskapsarkitektur ledde in på spåret att
diskutera vad två av dagens stora frågor inom ämnet kunde erbjuda om de slogs
samman; positiv psykologi (?Positive Psychology?) och hållbar stadsutveckling. Alla
människor utsätts emellanåt för stress, vilken vi är konstruerade att kunna hantera.
Trots det är en av de största orsakerna till sjukskrivning i vår tid just stress- och
relaterade sjukdomar. En välkänd källa till restoration eller återhämtning är grönska
och natur. Så frågan i denna uppsats rör huruvida små grönområden i den täta
staden kan verka restorativt på människorna som besöker dem.
Prevalence of subclinical mastitis in dairy farms in urban and peri-urban areas of Kampala, Uganda
En operation framkallar en icke önskvärd fysiologisk reaktion hos patienten som benämns som kroppens stressvar. Stressvaret innebär att sympatiska nervsystemet aktiveras och att endokrina ändringar erhålls, bland annat minskning i sekretionen av TSH och insulin samt ökning i sekretionen av ACTH, kortisol och ADH.
En viktig uppgift för en veterinär är att välja premedicineringsläkemedel innan en operation. Premedicineringsläkemedel har som främsta uppgifter att motverka det perioperativa stressvaret hos djuret, minska smärta och förstärka anestesimedlens effekt. Syftet med det här arbetet är att beskriva vad som händer i kroppen vid ett perioperativt stressvar och hur svaret kan motverkas med hjälp av premedicineringsläkemedel.
Premedicineringsläkemedel väljs och kombineras från klasserna sedativa, analgetika och antikolinergika. De vanligaste använda sederande läkemedlen på svenska veterinärkliniker är dopaminantagonisten acepromazin och alfa2-agonisten medetomidin.
Social hållbarhet och förtätning : en kritisk studie i förtätningens sociala paradoxer
Densification is one of the urban visions for sustainable development - a vision that has become a part of the solution to the unsustainable sake dilemma. With the dense city land will be saved, energy consumption reduced and social cohesion improved. The dense city is considered to be ecologically, economically and socially sustainable. Applying an urban design concept has thus proven to be problematic. Density has been found to be a complex concept
which is far more complicated than measuring how much built surface that needs to be covered.
It is also not disputed what different degrees of densification mean and whether densification in itself is sustainable.
Effektivare röjningssätt med kedjeröjsågen?
After the mandatory rules for clearing was removed in 1994, the clearing area has increased in Sweden. After the storms Gudrun and Per, the areas became planted with new plants, mainly spruce, but also other tree species. Storm areas are now being invaded by naturally rejuvenated birch in the tilling tracks. Since the birch often is initially growing faster than the spruce it is inhibiting the growth and is also damaging the spruce.
The purpose of this thesis is to study the new brush saw with chain and compare it with the conventional clearing saw, mainly in terms of performance and ergonomics. The results show that the new brush saw with chain is very good in almost all clearing operations compared to the conventional clearing saw.
Trygghetsskapande design av Mörby stadspark :
The purpose with this thesis is to investigate how to design a
urban space so that it is experienced safe and how to implement
this at an actual site. Knowledge on the subject has
been gathered through litterature studies and interviews with
experts. Through an analysis of the site with surroundings and
studies of projects with similar problems, practical actions
have been observed. Part taking in the municipalities planning
process has given insight in the projekt as an whole and
the interests of different parties.
There are many different opinions about what the word safety
means. It is a feeling depending on situation, that is affecting
our daily behaviour.
Tvärfunktionell produktutveckling : - En utredning på Scania om samverkan mellan konstruktörer och produktsamordnare
The role distribution between designers and product coordinators and the system support between these roles are adapted according to the method of working that product models primarily are created for production and after sales market. At the same time models are also created to support a cross-functional way of working. This means that product structures exists on paper and as CAD-models before they are created in Scanias PDM-system environment which leads to unnecessary work and to information not being shared as early as it should be possible.A theoretical study has been performed with the purpose of understanding the problems and to create a foundation for improvement suggestions. Representatives from both roles have been interviewed together with other individuals with insight in the collaboration. A minor study concerning the roles of interests? collaboration at Volvo CC was also performed to be able to relate the study to another company.
