Perenner i Norrbotten - Ja, varför inte? :
In this thesis, I have discussed which (herbacious) perennials that are sold most in
the county of Norrbotten in the upper north of Sweden. Also discussed are the factors
considering overwintering and factors that affect the chances of survival. The reason
to the subject is that I m born and raised in Norrbotten and throughout the years I ve
wondered why so many of the perennial flowerbeds look so similar. The purpose of
the thesis is to give another approach to the composition of the garden by explaining
some of the factors that controls the survival of plants. The information is gathered
partly through interviews with plantshop personnel and partly by a literature study.
The results of the interviews reveal that tradition and hardiness is the major reasons
to the consumer s choice.
Frigörelse av fosfor från färskt, fryst och torkat växtmaterial : ett laboratorieförsök för att öka förståelsen för fosfordynamiken inom växtodlingen
Phosphorus is the single most potent contributor to eutrophication of freshwater and has also been shown to contribute to the toxic algae blooms in the Baltic sea. The
dynamics and paths of losses of phosphorus from arable lands are not fully understood.
It is known that phosphorus can be lost directly from plant material to water.
In studies where plant material has been subjected to several freeze-thaw cycles, large amounts of phosphorus have been lost. Most studies have been conducted
under field conditions, with many factors effecting the measured losses of phosphorus, such as weather and type of soil. This study was performed in a controlled environment without the presence of soil. Instead of soil, small glass beads were mixed with the plant materials in vessels, to make possible homogeneous leaching with water through the mixture of glass beads and plant materials.
In this study, clover, ryegrass and dry straw were cut to pieces, approximately 2 cm long.
Avvikelser i energiprestanda
Calculated and measured energy in residential buildings is going to differ. The reason to this may be due to many factors. In this study there is a study on how these factors affect the energy use in a building. To get an insight in what defines energy, there is first a description of energy supply both worldwide and used in Sweden, followed by a description of the energy balance. In this study energy will be studied in residential buildings only.
Provtagning av trädkärnor för att bedöma föroreningsgraden av klorerade lösningsmedel i grundvatten
Chlorinated aliphatic hydrocarbons (CAH´s) were used widely within dry cleaning facilities and for metal degreasing until their toxicity was discovered. PCE is still used as dry cleaning liquid. Today CAH´s are found in soil environment at places where they have been used in the past. The CAH-concentration in trees growing on contaminated land has quite recently received attention as a cheap and effective way of assessing the extent of a CAH-contamination. The method has however, not been put into use in Sweden.The aim of the study has been to investigate whether the CAH-concentration in tree cores could be used to delineate the spread of CAH in a soil environment under Swedish conditions in different seasons.
Den geografiska, funktionella och processorienterade organisationen : en fallstudie av Holmen Skog, SCA Skog och Sydkraft Vattenkraft
This thesis reports on a case study of two different organisational forms in the Swedish
forest industry; the geographic and the functional organisation. The work in the
geographic organisation is carried out within districts under the supervision of an overall responible district manager, where as in the functional organisation the work has been divided into functions headed by function managers. Forest magement, logging and wood
purchases are examples of such functions. The general idea of the functional organisation
is having the functions working over a larger geographic unit, without subdividing
district boundaries of the region. Also a third organisational form of current interest for the forest industry; the process orientated organisation, is analyzed in the case study.
Here, a company outside the forest industry has been analyzed, since no forest company
was considered to have made as much progress of changing organisation to process
orientation.
In the report I present the results from qualitative interviews, where I give the reader a
picture of the motives behind each organisational form, what the form implies for some
of the company?s interested parties and the organisations? views on future organisational
development.
Energikartläggning av polishuset i Gävle : Åtgärdsförslag för ett minskat energibehov i fastigheten Gävle Söder 17:10
The objective of this work was to introduce measures to reduce energy and water demand at Gävle Söder 17:10. To succeed, this energy audit has been made. The work is based on collected statistics from the property owner Norrporten, measurements, literature review and through consultation with experts in the field. Two models, one for each building, have been created in the simulation program BV2 to estimate the potential of energy measures based on the collected information. The models in BV2 have been verified against the statistics of the energy consumption.With the help of calculations and simulations, seven cost-effective measures have been identified.
Social hållbarhet och attraktionsfaktorer i en urban kontext. Fallstudie över Malmös nya stadsdel Hyllie
Do new, attractive neighborhoods meet the requirements of being socially sustainable? This essay is based on the potential conflicts between the pursuit of social sustainability, while the theory of the creative class influence city planning. Social sustainability is difficult to measure, but implies broadly that everyone should have equal rights and opportunities. A city or region that aims to attract a certain type of people by providing what they ask for, might pay less attention and spend less resources on the rest of the population. Socially sustainable - for whom? The new district Hyllie in southern Malmö stands in focus, and the paper seeks to identify how different operators in Malmö defines the concept of social sustainability, how it is implemented in the design of Hyllie, and if any potential conflicts may arise.Interviews with the following informants; representants from the Office for City Planning in Malmö, the nonprofit organization Sustainable Development Skåne, the Commission for a Socially Sustainable Malmö and the company Skanska Öresund have constituted the main methodology, among with reading and analyzing existing documents and policies relating to the development of Hyllie.
Pellets - en framtidsmarknad?
With higher prices for oil and increased focus on fossil fuels impact on the environment the heating sector are searching for alternative fuels. Pellets are a quite new product whose production has risen exponential in recent years. Today there are small-, medium-and large-scale users, where the large-scale consumers are the heating sector. The heating sector is mainly using oil to cover the increased demand during cold periods.
The purpose of this study is to analyze the potential of pellets if it would replace thermal power plants oil and coal. The study will also analyze the economic impact a conversion would mean for a heating plant and if the pellet is a reasonable substitute.
2008 statistics from the Swedish district heating association were analyzed and a calculation was performed to determine how many tons of pellets is needed to replace coal and oil.
Ingen är utanför alla är inne : en studie om hur skolungdomar i ett segregerat område kan uppleva villkoren för sin utveckling av en självbild.
This study aims to describe the conditions, of which some youths who live in a segregated area in Sweden, see as important for their development of an identity. The study have been conducted in a manner where we put the youths own words in focus. The youths are in charge of deciding what they regard as important for their own development of their own identity. In this study we assume certain contexts, of which we base the study. These contexts include the society, the urban districts, the school, the family, and the language.
Behovet av Goodwill - En fallstudie av Just Water
Hur sponsring av ändamålsrelaterad karaktär kan användas för att skapa goodwill..
Översvämningskartering av Vombs ängar
Vomb meadows is an area well knows for its rich bird life. During the 19:thcentury until mid 20:th century, the meadows were flooded annually in order toincrease the hay yield. The river Klingavälsån situated along the west side of themeadows, used to be a shallow river, meandering across the landscape. In the1940?s the river was straightened and made deeper.
Dissekering av ett lokalsamhälle : En studie av sociokulturella mönster på småländsk landsbygd 1838-1845
Following essay examines the social and cultural patterns of southern rural Sweden between the years 1838-1845. The study is based on records from trials held by the district court of the district Norra Möre, which provides an insight to the everyday life in rural local community. Emphasis is put on exclusion and inclusion: the basis for community, codes for inclusion and exclusion, meaningful attributes, social and cultural capital etc. Questions concerning gender are raised as well as intents to discover whether modern ideas contrast early-modern, especially considering the process of individualization. Results show that concepts of confidence and trust were extremely valuable and possessed significant meanings. Confidence, which established itself on virtuous and honest life, created the framework for most aspects of social society: for example credibility inside and outside of court, maintenance of friendship and company, capacity of upholding a working life. Forfeit of trust, through extensive dissolute, mischievous and ill-considered way of life meant exclusion from the community and great vulnerability.
Fortsatt gran eller självföryngrad björk efter stormfällning? : en ekonomisk analys
The southern part of Sweden, Skåne, is frequently exposed to storms causing great damage to Norway spruce (Picea abies L. Karst.) stands. A storm during the winter 1999/2000 raised the attention of the problem. A lot of forest owners got large areas of spruce stands wind thrown during this storm. Can naturally regenerated birch (Betula sp.) be an alternative on these wind-exposed sites? This was the main question I was facing when discussilig the problems with Esben Möller Madsen, Söderåsens forest district.
The aim of this master thesis was to present an economic analysis of Norway spruce versus
birch.
Magasin för lagring av vatten och växtnäring
Structural rationalizations and regionalization of the agricultural sector in Sweden has lead to unevenness in thedistribution of plant nutrients. Nutrients are lost from crop producing farms as harvest products are sold, whilefarms with animal production often have manure in excess of their needs. In addition to this the retention ofwater and nutrients in naturally occurring wetlands has decreased due to a reduction of wetlands in number andsize in the agricultural landscape. This increases nutrient levels in agricultural run-off and causes eutrophicationas well as nutrient losses from arable soils. One potential solution to both problems would be to store nutrientrichsurface water from agricultural areas and use it for irrigation of agricultural crops.
Erfarenheter från Olika Produktutvecklingsprocesser vid Utvecklingen av en Atmosfärisk Vattengenerator
This Master of Science thesis was completed at the Department of Machine Design at the Royal Instituteof Technology in Stockholm in collaboration with Lund Faculty of Engineering, Luleå University ofTechnology and Stanford University. At Stanford University a global product development project wasrealized as part of the course ME310. The project was initiated by the American company ImmerseGlobal whose vision was to develop a new type of Atmospheric Water Generators, a machine that absorbsthe moisture in the air and via a water system transforms it to pure drinking water. The project was partlyfinanced by the Product Innovation Engineering program, a Swedish research and development programfor increased innovation capability in organizations.In parallel with the global project in the ME310 course the product development process was studied inorder to compare it with a product development course at the Royal Institute of Technology, IPU. Thetwo courses are similar to each other in several aspects.
