Kostnadsutvecklingen inom flottningen i Dalälven 1900-1970

The paper, with a brief summary of timber floating in Sweden and also of some previous re-search in this field, contains a study on costs for timber-floating in the river Dalälven located in central Sweden. The public used timber-floating system in Dalälven and the historical background about this activity is described. The study is focused on the total costs for timber-floating in the public open floating system in Dalälven from 1900 to 1970, the year before the timber-floating was definitively closed down. Also the costs for separating the logs of a specific owner when they reached the point where they could be separated from the timber of other owners are analyzed..

Upplevelser av att ligga i flyttank - floating

Det moderna informationssamhället har medfört en ökning av upplevd stress. Avslappningsmetoder används som ett sätt att motverka hög anspänning. En relativt ny företeelse utgör floating, där man flyter i saltkoncentrerat vatten inuti en stimulireducerad flyttank. Forskning har påvisat gynnsamma effekter av floatingutövande. Syftet i denna studie var att undersöka individers upplevelser av att ligga i en flyttank.

Småvatten då och nu : en förändringsstudie av småvatten i Skåne och deras kväveretentionsförmåga

Wetlands play an important role in the ecosystem. They reduce the impact of flow flux in the drainage area, acts as upholder of biodiversity, as an esthetic and recreational component in the landscape and they have the ability to reduce nutrients such as nitrogen, and help preventing eutrophication in costal areas.The number of wetlands in Scania have, due to the intensified agriculture been reduced to maximize the area suitable for crops.However since the mid 80th the consequences of this has been acknowledged, and many wetlands have been restored.This master?s thesis aim to see what impact this development have had on wetlands in Scania over the last 60 years. And also look at some of those factors important for the efficiency of nitrogen removal in wetlands. During the process a detailed manual for inventories of this sort was created.The material used to execute the inventory of wetlands where aerial photographs over Scania from the 1940th, 1980th and 2000.

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.

Betydelsen av anlagda våtmarkers area och ålder för förekomst av sjöfågel inom Linköpings kommun

The aim of this study was to examine what impact restored and constructed pounds and wetlands have on waterfowls in the area of Linköping. The birdlife in five constructed wetlands werechosen to investigate if specific factors like age, size and vegetation affected the avian diversity in wetlands. Also, extra focus has been given to the threatened Horned Grebe (Podiceps Auritus), breeding in the studied area. The results showed that the number of species as well as individuals of waterfowl and Horned Grebe changed over time in what might be a result of succession in the wetlands. Comparing the number of birds to the size of the wetlands showed a clear correlation. Larger areas inhabited greater numbers of species and individuals.

Konstgjorda våtmarksöar : flytande reningsverk?

År 2000 godkände Sverige EUs vattendirektiv. Det innebär att vi måste arbeta för att vattnet ska ha en god kvalité och det får inte ha för höga halter av förorenade ämnen. Vid förorening kan vattnet skada människor, djur och växter. Sverige måste ständigt jobba och förbättra reningen av vårt dagvatten. Reningen av dagvattnet och på vilket sätt det ska ske är något som ständigt kan förnyas och förbättras. Idag renas dagvatten med hjälp av dammar och våtmarker och reningen kan bli bättre med hjälp av flytande våtmarker. Syftet med denna uppsats har varit att ta fram mer information om flytande våtmarker och att sprida denna så att intresset och kunskapen ökar och förhoppningsvis även användningen av dem så att reningen av dagvattnet kan förbättras. Arbetet innehåller en litteraturstudie och resultat från intervjuer vilka bägge syftar att ta reda på hur en flytande våtmark fungerar, hur den är konstruerad, vilken typ av skötsel den kräver, vilka växter som fungerar bäst, hur de renar vattnet och hur man skulle kunna använda sig av dem här i Sverige. I arbetet finns det information om när en flytande våtmark renar som bäst, vilka typer av växter som bör användas och vilka typer av stommar det finns till den flytande våtmarken.

Marknadsföring på ett djupare plan : En fallstudie av Aqua Floating i Kalmar

Floating innebär att man ligger i en tank med tempererat saltvatten som gör att man blir tyngdlös och flyter. Floating kan bland annat minska ner stressymptom. Kundens konsumtionsbeteende styrs i hög grad av varumärken. För att stärka ett varumärke måste relationer skapas med hjälp av värdeskapande aktiviteter. Sinnesmarknadsföring är ett sätt att nå ut till kunderna på ett djupare plan och stärka deras relation till varumärket och varumärkets identitet genom att integrera de fem sinnena i marknadsföringen.

Amfibier i nyanlagda våtmarker : En fältstudie i Laholms jordbrukslandskap

Many species of amphibians are threatened both in Sweden and globally. The causes are many and a main factor is habitat alterations which often results in populations being isolated. Changes in the agricultural landscape have among other things resulted in small water bodies being filled and dried out and that has severely affected the Swedish amphibians. Swedish amphibians are depended upon small water bodies for their reproduction. Wetlands have been constructed to reduce the impacts of the eutrophication in the Laholm bay.

Translokation av större vattensalamander : -bevarandestrategi eller riskåtgärd?

This study evaluates the retention of nitrogen and phosphorus in four newly constructed wetlands in the municipality of Falkenberg, Sweden. The four wetlands have been selected because they have been specifically constructed with the aim to reduce nitrogen and phosphorus in farming areas. The process of selecting the specific wetlands has been done in collaboration with the county administration in Halland. Through field studies in collaboration with the landowners where the wetlands are sited, the areas that provide the wetlands with water were determined. The size of these drainage areas were determined in a GIS computer program. The type of land use within the drainage areas was also determined.

Referensvåtmarker för uppföljning av växtnäringsretention i anlagda våtmarker

One of the environmental problems today in seas, lakes and streams is eutrophication. This is often caused by nutrients such as phosphorus (P) and nitrogen (N) that leak from agricultural areas. A measure to partly prevent the nutrient discharge is to construct or restore wetlands.In order to control the efficiency of nutrient reduction of existing wetlands in the county, the administrative board in Västra Götaland wants to find different criterias for reference wetlands. These reference wetlands should represent other wetlands and be used in future evaluations of reduction of nutrients and design of constructed wetlands. According to the administrative board in Västra Götaland the reference wetlands should have a catchment area of about 50 hectare consisting of at least 70 % arable land, to represent wetlands created to remove nutrients.

VISION SJÖSTAD : Flytande Bostäder

Floating housing is a concept gaining ground in Sweden. The dwellings are different in many ways from traditional homes, not only regarding flotation, but also several other technologies. The purpose of this thesis is to emphasize the qualities that exist in living on water. The ambition was to present a proposal for a floating residential area located in Jönköping, containing homes of varying sizes, and to present their technologies. In order to find inspiration and solutions studies have been made on existing floating homes in Stockholm and Kalmar, focusing on their technical and functional solutions.

Ombyggnation, från sågverkslokal till restaurang. antonio ziakoulis

Pharmaceuticals that are found in marine ecosystems are a threatening environmental concern, which is known to harm both animal and plant life. One of the reasons for this problem is that the waste water treatment techniques are not optimized to clear waste water from its pharmaceuticals contain. In this master thesis four Swedish treatment wetlands were studied, and their ability to reduce numerous pharmaceuticals in waste water. The four treatment wetlands that were studied were those in Oxelösund, Trosa, Nynäshamn and Eskilstuna. Two ecotoxicological tests and chemical analysis were used.
