Marktäckande, lågväxt vegetation på ställverksmark : en biologisk bekämpningsmetod mot ogräs
Unwanted vegetation on the land of electric transforming stations is a problem, in the sense that it contributes to higher fire risks and also constitutes an obstacle for people performing maintenance operations at the station. Such unwanted vegetation is controlled using herbicides and mechanical measures. Since the use of herbicides implies environmental hazards, there is a need to find alternative ways of fighting the unwanted vegetation.
Investigation into suitable plants for ground cover, trials in the greenhouse, trials in the field, soil analyses and compilation of experiences from similar trials are parts of this work. The paper also contains analyses of possible environmental benefits and economical gains. There is also a final discussion of some proposals regarding alternative weed controlling methods.

Förändringar i markanvändning över tid och dess påverkan på vattenkvalitet
The EU Water Framework Directive has led that management follows the boundaries of natural catchments.The Swedish waters suffer from a nutrient overload that originates mainly from diffuse sources such as agriculture and the subcatchment of Hackstabäcken in Vallentuna Kommun, just north of Stockholm, has been chosen for this study because of its high nutrient load and because it has undergone obvious changes in land use through the years.In this study, the land use in 1902 is compared with the land use in 2011 in order to investigate if it has influenced the ability of the landscape to produce ecosystem services related to nutrient removal. These services will continue to be produced as long as the system is stable and resilient, but when landuse changes and manure from horses increases it will lead to disturbances that can convert a system from one regime in to a completely different one. That will result in loss, or degradation, of ecosystem services such as denitrification, phosphor sedimentation and adsorption, vegetation uptake and infiltration.The results of this study are based upon area calculations of landuse from old maps from 1902 and 2011. Through these maps it becomes clear that the forests in Hackstabäcken, has increased with 170 ha together with an urbanization of 311 ha, at the same time as wetlands and arable land has diminished and lakes has suffered from reductions. Wetlands have been reduced with 76 ha and the ones remaining are of insufficient quality from a nutrient removal perspective.Data from 1902 and 2011 regarding number of horses and bovines indicated a decrease in bovines and an increase in horses.
Gremmeniella abietina-epidemin 2001 : har skogen återhämtat sig?
The fungus Gremmeniella abietina causes damage to conifers that can lead to tree death. In 1999 and 2001 the pathogen caused severe attacks in Sweden, where about 500 000 ha of pine forest were affected. Trees of all ages were attacked, but mainly forests between 30-60 years that were ready for their first commercial thinning. After recommendations from the forest agency, sanitary fellings were made to trees that had more needle loss than 85%, a total of about 50 000 ha. Economic losses have been estimated to more than one billion SEK.
Framtagande av riktlinjer för arbetsplatsbesök enligt nya Plan- och bygglagen
A new site- and construction-law came into effect in May 2011. The new law, PBL2010:900 implies several different changes of the law. These changes concern bothconstructors, people working in municipality and county councils and other peoplethat in some way are related to the building sector. Except from the change in orderof the chapters and the renewed and modernized language, the law has now beenextended with a few new phases.According to the new law a certificate has to be issued to start and finish theconstruction; the construction consulting has changed name into technical consultingand the protocol for the controls has to show what the control is being compared to.This diploma work concerns control visits on construction sites as related to the newlaw. The reason why visits on construction sites are now implemented in the law isbecause the government saw a lack of trustworthiness in the old law.
Johannishusparken : historia, nutid, framtid
Summary
The estate of Johannishus is situated in the south of Sweden and in the province of Blekinge, about 8 kilometres from the city of Ronneby. The main building together with the park represents the province´s only example of a well preserved estate environment from the early 1800th Century, and was declared as a historic monument in 1982 because of its unique role in the province. Johannishus Park has during 300 years developed in close relation to the main building, the landscape and the surrounding infrastructure. Each century and owner has had an influence on the park, which has resulted in an interesting visible cross-section of 300 years of Swedish garden history. Most noticeable today are the traces from late 19th Century, but in its oldest parts the park contains structures from the early 18th Century.
Stadsnära hav : en intervju/enkät om upplevelsen
The environment that surrounds us affects us all. Research
has shown that we feel physically and emotionally best in
natural environments with greenery or water elements. Urban
environments are likely to be more stressing then natural
environments. How we experience specific elements, as water,
of an environment is not as much investigated. There is a need
of further knowledge for us to fully understand the interplay
between our senses and the environment.
Human beings have always been depending on water and the
search for it has characterized our deeds and doings through
out evolution.

Nedskrivningsprövning av goodwill : En studie av diskonteringsräntor på Nasdaq OMX Stockholm
Goodwill accounting has for a long time been, and with the implementation of IFRS in 2005, has become an even bigger issue. Critics mean that reporting of goodwill impairments is subject to discretion that can be used by the managers. We have applied a study made by Carlin and Finch (2009) on Nasdaq OMX Stockholm during 2006-2012. Our study contains 50 of the 255 public companies at 2012-12-31. The purpose of the study is to investigate if companies use an opportunistic discount rate when testing for impairment in goodwill and if the relation between goodwill and net profit before taxes, goodwill intensity, is an incentive for opportunism.

Design av utomhusträdgård i Dubai :
To plan and build a garden in Dubai has other conditions and challenges than what you experience in Sweden. The heat, wind and lack of water makes the need for durable plants, a good design and landscaping important if you want to have the opportunity to use your garden during most of the year. The soil is poor of nutrients, alkaline and sometimes saline, witch makes supplying the soil with organic material and various fertilizers necessary if you want to be able to plant a bigger range of plant material in your garden. Another important part is to provide your garden with a good irrigation system that should be put into the ground before planting so that the plants are given a more even irrigation.
It?s relatively green scenery you meet and to me it?s in a way surprising since the country with its climate is rather harsh for the purpose of supporting plant life.
Offentlig upphandling av anläggningsarbeten enligt lagen om offentlig upphandling LOU
This report is written in cooperation with Eskilstuna municipality public administration for urban planning. The reports purpose is to look into how other public authorities carry out public purchase of consultants and entrepreneurs in the urban planning area. The goal is to come up with suggestions of how Eskilstuna municipality public administration for urban planning can improve its purchasing process in this field in order to minimize the risk where a consultant or entrepreneur files an appeal against the decision of awarding a contract to another rival. The appeal can be filed to the county administrative court.The public administration for urban planning can do its purchases through the model of "lowest price" or "economically most favorable" for them. When using "economically most favorable", the department can value a number of soft parameters by giving them points and the offer which gets most points can be rewarded the right to sign a contract.
