Våtmarker i urbana miljöer : växtgestaltning och planering
The practice of landscape architectural involves forming the space in our cities and suburbs, as well as the landscape surrounding. The need of exploiting green environment leads up to, among other issues, flood problem during heavy rain and overfed water environments. The problem is partially caused by the shortage of knowledge, how the environment is responding of the innovations made by the city- urban planning and how to get sustainability.
Research and knowledge how to take care of our environment, in a natural way, is increasing. The object of the thesis is to propose control and balance in urban wetlands, and discuss the difference a plant design can do.
The thesis deals with discourses in the field of landscape architecture, biological diversity, dam construction, limnology, planting design and management, pollution of the environment and urban design practice.
Våtmarker för näringsretention i Lillån : var bör de ligga och vilken effekt kan vi förvänta
Construction of wetlands in the agricultural landscape may reduce nitrogen and phosphorus
transfer to streams, thereby reducing the eutrophication of lakes and seas. The agriculturalstream Lillån, a tributary to stream Sagån, ends up in Lake Mälaren and is transporting large amounts of these plant nutrients. The aim of this study was to estimate how hypothetical wetlands of different size and location may reduce nitrogen and phosphorus load from stream Lillån. Estimated nutrient retention in several small wetlands was compared to retention in a single large wetland based on existing data from the agricultural stream and from a nearby smaller stream. Retention in the stream was suggested to decrease along with the nutrient concentration in the water.
Sveriges handelsvägar för tomat och äpple :
The market of fruit and vegetables develops continuously to become tougher and more complex.
The fast development makes it difficult to keep up with all the changes. This is the case for
apples and tomatoes. The purpose of this work is to explain what the trade routes are like for
Swedish imports as well as the Swedish production of tomatoes and apples, both in the present
and the past times. There is also an ambition to create comprehension of the trade routes.
Näringsretention i återskapad våtmark på betesmark : studier av en mad vid Bornsjön
It is important to construct or recreate different types of wetlands and study their retention of nutrients, since knowledge of their effectiveness in this matter is poor. In 2003 a wetland was constructed on an old meadow on the western shore of Lake Bornsjön in central Sweden. The main purpose of the wetland was to reduce the amount of phosphorus entering the lake, which is the back-up water supply for Stockholm when the city cannot obtain water from Lake Mälaren. Large areas around Lake Bornsjön consist of agricultural land and the nutrient concentrations in the inflows to the lake are usually relatively high (approx. 1 mg/l total nitrogen and 0.05-0.1 mg/l total phosphorus).
Vi har i alla fall tipsbolag : En studie av möjligheterna att styra med belöningssystem inom kommunal verksamhet
Background: The use of reward systems can be of strategic importance as well as an affective mean of control for the organization in its work to achieve its goals. The municipal sector is characterized by its transparency and its responsibility for the taxpayer?s money. We therefore wonder which possibilities the municipal sector has to use reward systems as a men of control. Purpose: We intend to research the possibilities that the reward system offer as a mean of control for employees at the higher municipal level, with a special focus on commitment and motivation.
Framtidens Hus
The company Sol & Energiteknik wanted to examine the possibility to make a standardhouse totally energy independent. Based upon this I have, during the spring of 2007,examined the possibilities available at the market today through litterature studies, contactwith several companies and reading reports at the internet.The first thing to examine has been to determine the energy consumption for a standardhouse, and find out if there are better technologies to be used for energy conservation.My conclusion in this matter is that there are possibilities today for building a house moreenergy efficient.When I had reached the point at which my design for the house was decided, I also hadto choose the different products to use to produce energy as well as to store that energy.To produce heat and electricity to the house I decided to use a wind turbine and a solarwater heater.The most difficult part of designing a house that is energy independent is that theproduced energy must be stored somehow. Storing the heat is relatively easy beacuse theheat can be stored in a large water tank. The electricity is a bigger problem beacuse itmust be stored in batteries, which today are too expensive to be used in a standard house.In the future producing and storing hydrogen might be used to produce electricity, buttoday that technology is both expensive and not tested enough.My final conclusion is that a standard house can not be built to be totally energyindependent today, unless it is very expensive to connect the house to the electricitynetwork. As an alternative solution I came up with a proposal for a house which isconnected to the electricity network and have some amount of own produced energy.This house prooved to be a good investment if you choose to build it today, and it couldbe a very good investment in the long run beacuse energy prices increase every year..
Torkning av vallfrö :
In Sweden, grass is the single largest crop grown. Nearly 1 000 000 Ha grows on the
fields, this is primarily used as feed for livestock. To get a good seed, you need to
handle the crop carefully from planting to delivery. The part that I have been
interested in, is how to dry the harvested seed with out destroying the growth in the
small seed. This is very easily done if you aren?t careful during the drying period.
Utveckling av drivrutin till Intermec Easycoder 501 XP
We got in contact with Marco AB, who we?ve had contact with before concerning earlier projects, to find out if they were interested in arranging a larger project for our last class (Examensarbete 15hp). They were very positive to this proposition, and soon they offered us a project regarding reconstruction of their current mechanical device that absorbs all the force from the lift itself when it is at a predefined level (sv. sjunkspärr). The current solution does fulfill the requirements that are given, however it is not a solution that gives a high level of satisfactory.

Optik och ljus eller varför himlen är blå : En studie om genus och flickors intresse för teknik
The purpose of these studies is to see how the reception and education of non-Swedish speaking newcomers are organized in a small county, and what you can do to improve this process to achieve a better and quicker integration into the Swedish language and society. To do this, interviews have been performed with four headmasters and different categories of teachers representing all schools in the actual county.In the result it was clear that both headmasters as teachers saw a need to change and improve reception to provide consistent but flexible support. The headmasters wanted to create written instructions to assure equivalence between the different schools. The majority of teachers wanted to change the current system whereby some pupils, based on their origins, were placed in a preparatory class to learn the language whilst others were placed directly into a Swedish class. All teachers also thought that the help the non-Swedish speaking newcomers were offered was insufficient.The conclusion is that the county must decide and create instructions according to Skolverket?s recommendations and it also ought to offer all pupils the possibility of learning the basis of the language in a preparatory class.
Lojalitetsplikt och yttrandefrihet i sociala medier
The purpose of this thesis is to investigate the employees´ duty of loyalty to their employer when making statements on social media networks and if this opposes the employees´ right to freedom of speech. Another purpose of this thesis is to investigate freedom of speech from an EU juridical point of view. Also a discussion concerning gender issues on this subject takes place is presented in the thesis. The questions to answer the purpose of this thesis are the following: Where is the line drawn for what an employee can publish on a social media network without breaching their duty of loyalty towards their employer?, and How does an employee´s freedom of speech relate to these types of statements on a social media network? The method used for this thesis is the classical legal method.The legal inquiry shows that duty of loyalty is a hidden clause in all employment contracts, and it must be respected by the employee.
Finns det skillnader i känsla av sammanhang mellan personer på monotona och icke -monotona arbetsplatser med hänsyn tagen till syskonplacering?
AbstractThe aim of this study was to examine whether there are differences in Sense of Coherence between people in monotonous and non ? monotonous jobs with regard to birth order. In this present study, 89 individuals from three different working organizations participated, of which 51 (57, 3 %) of them were men and 38 (42, 7 %) women. The results showed that in varying occupations, firstborn children showed a higher level of Sense of Coherence. In monotonus jobs, middle children prove to have the lowest level of Sence of Coherence.

Valfrihet för äldre : En kvalitativ studie om implementeringen av ett valfrihetssystem och dess förväntade effekter i en utvald kommun
I have conducted a qualitative study were the aim was to understand how the freedom of choice act in eldercare is handled at a municipality level as well as a national level and the effects that can occur. The methods I have used for this study is a document analysis and semi-structed interviews. I have conducted semi-structed interviews with three professionals in the eldercare organization in a large municipality in the south of Sweden, I have also conducted a phone interview with a representative from Socialstyrelsen. The professionals that I chose for my study was a chief of staff, an aid case worker and a person who worked in the municipality with the implementation of freedom of choice act. The study shows that the work quality is expected to rise with the freedom of choice as a consequence of the customer and performer model and will give the caretakers a higher level of influence. The study also shows that the municipality will get a greater responsibility and the aid case workers will get extended tasks though they will have to inform the caretakers regarding the options and they will also be mediate between the caretaker and the performers. However the study also show concerns regarding rough traders whose aim is to make money and does not have the same rehabilitation agenda. There are also concerns for those who can´t chose for them self though they will not be able to be a part of the freedom of choice act in the same way and that is something the municipality needs to work out a system for.
Allt är möjligt hus i Gustavsberg
In a sequence described in the next paragraphs, I remove the poorly insulated roof of Gustavsberg Porcelain Factory and make new use of its foundation. The monolith cement slab, once supporting heavy industrial machinery, is now the site of lakes and other movements:The top floor area is split, and a new built volume, one story higher, overtakes the southern half resting on the factory?s basement, digging into it at its western and eastern ends. Striking horizontally, the fissure exposes a long central axis, taking advantage of the factory?s horizontality to articulate vastness .
