Forsknings- och utvecklingskostnader : Definition och anskaffningsvärde ur ett skatterättsligt perspektiv.

Research and Development-costs constitutes an important part in contemporary companies. R&D are treated differently depending on their definition and how the historic value is decided. The main goal for this essay is to bring clarity to how the definiton of the term R&D is decided in accounting as well as in tax law. Another goal is to decide how the historic value is calculated. It is also interesting to examine under which circumstances the costs can be activated in the balance sheet, and under which circumstances deduction for the R&D-costs may be allowed.

Byggnadsminnesförklaring : ett långsiktig hållbart skydd?

There are currently 2160 buildings in Sweden that are protected by law with the designation as a cultural heritage building, which is the strongest protection that can be obtained for a building of cultural historic significance. The purpose of this thesis is to research how strong and sustainable the protection of such a designation is and how you can motivate a revocation. Furthermore, this thesis aims to give an overall insight into all cases where there has been a revocation.To achieve the protection of a designation as a cultural heritage building, the object has to be of outstanding interest on account of its cultural historic value. In the first part, this thesis gives a short historic background of the cultural heritage law and its terms, like outstanding interest and cultural historic value. The County Administrative Board's documents about revocation are the main source for this research.There have been 24 cases of revocation and the frequency of such cases has increased in the past ten years.

Växtmaterialet i 1700-talets engelska park : en växtplan för Engelska kullen på Gunnebo

Gunnebo House and Gardens was designed during the late 18th century by architect Carl Wilhelm Carlberg as a summer residence for the wealthy merchant John Hall Sr. and his family. The garden consists of formal garden, kitchen garden and English park. For the first two parts several original drawings have been preserved and here a lot of restoration work has been carried out. This paper aims to examine how the English park might have been implemented during John Hall Sr.?s time and to create a plant scheme for the area called ?Engelska kullen? (The English hill).

Handbok för växtinsamlare : med erfarenheter från sex nutida svenska experter

What makes a Swede betake himself into the Chinese wilderness? How does the Rio Convention influence a plant collector? And who will crack the nut positioned 12 meters up in the crown of a tree? There are many secrets behind the act of collecting plants. In many regards, the documentation of the collection of plants for a Swedish purpose has been unsatisfactory. The focus of the publications is on what plant species that have been found rather than information on how these plants have been collected. Only few results of experimental cultivation are available. There is no doubt that there exists knowledge that has not been publicised yet.

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.

Val av komplementmaterial för våtkompostering av klosettvatten

Emissions of insufficiently treated wastewater, mainly blackwater (i.e. wastewater from toilets), contributes to the eutrophication of lakes and seas. At the same time, blackwater is a fraction with a low content of heavy metals and, after sanitization, it can recirculate plant nutrients to arable land using the liquid composting treatment method. Liquid composting means that organic material is degraded under aerobic conditions. For sanitization, the blackwater needs to be treated together with energy-rich complementary material.

VäxtVäktare

Most people have been forced to throw away a pot-plant after its death. There are many reasons to the death of a plant, but mainly it?s because its owner forgets it, and therefore fails to water it. The purpose of this project is therefore to develop a product which can prevent this from happening, while the product has to have a low manufacturing cost to be able to compete whit other, similar, products on the market. During the project, a benchmarking has been done to give a clear picture of what the product has to compete with. The directives there are for CE-marking, and which of these who concerns the product has also been looked up.

Transport och terminalhantering av plantor på Södra

This study has been carried out at Södra´s 31 local forestry districts and within six plant terminals. The production and sale of seedlings at Södra is managed in collaboration with ?Södra Odlarna?. Approximately 35 million plants are cultivated each year, providing Södra´s members with a wide choice of high quality plants. The seedlings are nurtured at nurseries before transferred to plant terminals where they are stored and watered.

Kväveomsättning i gräsmark med olika artantal och artsammansättningar :

This study was carried out at the Swedish University of Agricultural Sciences, Dept. of Agricultural Research for Northern Sweden. The aim of the study was to determine how plant species richness and diversity influence the nitrogen pools and nitrogen fluxes in the soil. Plant and soil samples from a biodiversity experiment in grasslands were used. Thirty plots with 12 grassland plant species (legumes, grasses, and non-legume herbs), combined from 1-12 species were investigated.

Inventering av processvattenbalans : fastställande av fjärrvärmedistributionens läckage inom Vattenfall Värme Uppsala AB

Heat is distributed to the district heating customers through pipes with water as a heat carrier. The district heating system is complex. To decide what is leakages from the district heating net versus what is the water consumption of the plant, is difficult. Therefore, the purpose of this master thesis is to establish a model where the district heating net?s leakages but also the water consumption of the plant can be followed daily. The project is performed at Vattenfall´s district heating power plant in Uppsala. Information is gathered through discussions, drawings of the plant and guided tours of the plant.

Möten i kulturmiljöer : En studie av publika insatser i samband med arkeologiska utgrävningar

This essay is focused on the questions of and responsibility for where, when, how and why communication and meetings through archaeology should take place. I have critically studied Swedish public archaeology through three diverse archaeological excava­tions, one took place in the end of the 1980s, and two others in 2012.I have asked for under what circum­stances and with which goals the public efforts become possible. I have inter­viewed leaders for the archaeological excavations and/or the public efforts and questi­o­ned how and why they reached out to the public. I also searched for results and effects in order to problematize and value the public activities.Through interpretation of the resear­ched material it becomes clear that economic issues as well as archaeo­logists interests and engagements are of vital importance for public archaeology. Co-operation in the local community and archaeological documentation is crucial for the deve­lopment of archaeology and its role in society.Keywords: Public archaeology, Community archaeology, Heritage, Communication, Manage­ment, Historic environment education, Time Travel, Living history.

Älgarås avloppsreningsverk- studie och metodisk felsökning av en biobädds BOD-rening

Wastewater contains biodegradable materials, which are often measured as BOD7.Trickling filters are sometimes used as a purification step for BOD-reduction. Atrickling filter is a tower, which is filled with a carrier material. Microorganisms growon the carrier material in the form of a biofilm. This biofilm consists mostly of bacteriathat purify water from BOD.In Älgarås? wastewater treatment plant the water is purified by a trickling filter.However the treatment plant has difficulties reaching the emission requirements forBOD.

Mekaniskt snytbaggeskydd

Insecticides will be removed from Swedish forestry, at present insecticides are used to treat our seedlings to avoid them from being attacked by pine weevils. With the forthcoming ban on insecticides alternative protective measures will have to be tested. Holmen Forest Ltd has aimed to find an alternative and have developed a mechanic pine weevils protection accessory as well as a new concept on planting pipes. Studies have been conducted on the behalf of Holmen Forest Ltd to see how planting with the newly developed mechanical protectors and plant pipe stands up against the conventional methods used today. The study was conducted over a three week period. Three factors were compared regarding planting quality including i) pressure around the plant, ii) the depth the plant ended up in, iii) plant angle. Mechanical plant pipes were used in the study, and where tested like a one-handed and a two-handed pipe. The study concludes that further development is needed for the mechanic plant protector to live up to the speed and quality of conventional methods.

"De tycka emellertid av gammal vana att det smakar gott, och tro dessutom att det är bra för hälsan" : samiskt växtutnyttjande från 1600-talet fram till ca 1950

Meat and fish was the most important food for the Sami people in northern Scandinavia until the beginning of the 20th century. It is not so well known that the Sami people also used a lot of wild plants as food and medicine although that kind of food was relatively common among them until the end of the 19th century. The purpose of this master thesis has been to describe which plants the Sami people used in general and also which plants were the most commonly used, and when and how these plants were harvested. I also wanted to measure the quantities of Angelica archangelica and Rumex acestosa within traditional harvest sites. Furthermore I wanted to find out if the plant use differed among Sami groups geographically.
