Kan markfuktighetskartor användas för att hitta skogsmark med hög bonitet? : ett gis-baserat försök med dtw-index och laserskannad övre höjd

The depth-to-water-index (DTW-index) is derived from digital elevation models (DEM) to map soil wetness, in terms of distance from soil surface to the ground water table. The aim of this GIS based study was to investigate the existence of a relationship between DTW-index and forest site productivity (SP). The belief of such an assumed relationship was based on knowledge that the ground water level is related to site properties that can either promote or impede tree growth. Data primarily comprised rasters of the Krycklan catchment in northern Sweden and depicted DTW-index and a laser scanned vegetation height. The 100th height percentile of each pixel in the vegetation raster was assumed to mirror the top-height, letting it act as a relative measure of SP within a delineated area of equal stand age.

Fältdiagnostik - ett verktyg för hållbar odling : Resultat och tillämpning av fältdiagnostiska metoder i planeringsstadiet av en ny trädgårdsblåbärsodling

I det här arbetet undersöks fältdiagnostiska metoder och användbarheten av dess resultat i planeringsstadiet av en ny trädgårdsblåbärsodling. Syftet är att fastställa vilken information som kan erhållas från en jordanalys, penetrometerundersökning och en jordmånsbeskrivning samt vilka rekommendationer från dessa undersökningar som vidare kan härledas till planeringen av en ny trädgårdsblåbärsodling. Som exempel och fallstudie används en bit åkermark i Ockelbo där provmätningarna ägde rum.Resultatet visar att fältundersökningar i kombination med en jordanalys gjord på laboratorium är ett bra verktyg för att utreda en jords grundläggande förutsättningar. Jordanalysen visar hur näringsinnehållet ser ut i jorden samt vilka eventuella näringsbrister eller näringsöverskott som finns. Penetrometerundersökningen informerar om eventuella markpackningar, som utgör eventuella hinder för t.ex.

Texturbestämning genom fält-, pipett- och hydrometermetoder :

Texture is an important soil property and accurate particle size analysis of soil texture is therefore crucial. There are a number of well-established and newly developed methods available for determining soil texture. In order to compare the results of these methods, the differences between them must be determined. The difficulties, problems and differences regarding texture class determination were examined through a study performed on forest soil samples. The study compared different methods (pipette, hydrometer and field methods) and two types of dispersing agents (sodium pyrophosphate and sodium hexametaphosphate (calgon)) commonly used for particle size analysis.

Fibulas vikingaby på Åland - En undersökning om hur man kan förbättra, utveckla och tillföra nya idéer till en nutida vikingaby

In this essay I try to look into how to bring a new concept to an already established Viking village and how to develop the existing one. This essay also sheds light on some negative sides that a Viking village can experience in their activity.I have interviewed responsible persons at three different Viking villages: Foteviken Museum and Viking Reserve, Fornföreningen Fibulas Viking village and VikingaTider. I have also examined different kinds of literature dealing with my chosen Viking villages.I came to the conclusion that I should have chosen an other Viking village than VikingaTider because a lot of VikingaTiders activity hasn´t really started yet. On the other hand it has been interesting to see how they are trying to start the activity and which their plans are. I could have chosen an other already established Viking village to get a more varied material.There are a lot of things that Fibula can do to improve, develop and bring new aspects to their concept.I have found both advantages and disadvantages with the different Viking villages activity and strategi.

Inventering av förorenad mark på LKAB´s industriområden i Kiruna, Svappavaara och Malmberget :

The county administration asked LKAB to make an inventory of possibly contaminated sites caused by their mining activity. The inventory should be performed according to the MIFO model, a method from SEPA which is used to assess a contaminated site. The first phase involves collection of information through interviews and site inspections and in phase 2 a general survey with field sampling is conducted. LKAB started the work with the first phase of the survey during 2003. During this project the information collected in Phase 1 was evaluated and 16 of the sites were chosen to proceed to MIFO Phase 2 (six sites in Kiruna, and 5 sites respectively in Svappavaara and Malmberget). The sampling of these 16 sites was performed during week 27 2004.

Teknik i förskolan : Planerad och oplanerad verksamhet

Summary The purpose of this research is to find out if technology is being used in pre-school activity, to what extent, in which way and what part the pre-school teachers believe they should have in the process. To gather information for the research, questionnaires were sent out to all pre-schools in a municipality in central Sweden. Based on that information two were chosen for observations and interviews. The work with technology in pre-schools may vary. Some pre-school teachers believe they do not adopt any technology at all when asked and all this because of their own lack of interest or knowledge, while others believe it is contained in all of their educational activities.

Arkitektur på naturens villkor - Att bygga med "cradle to cradle" som metod

ABSTRACTThe discussions about energy use have increased year by year everywhere in the society, and so also in the healthcare sector. But what is actually energy use in a hospital facility, and what affects it?The typical way today to express the energy use is in kWh/m2. The problem with a key performance indicator that is expressed as energy use in relation to a specific area is that it does not take into account the activity in the building. Even though the activity to a very high extent affects the energy use.

Återgång till fysisk aktivitet hos män efter en främre korsbandsrekonstruktion

 Background: Earlier studies show that 30-92 % of ACL reconstructed return to their pre-injury physical activity. It is not clear why some people do not return.Purpose: The purpose of this study was to investigate the return rate to pre-injury sport among ACL reconstructed men. Another purpose was to characterize those patients who return and those who do not.Metod: A Web-based questionnaire with questions about returning to physical activity was sent out during the spring of 2012 to 93 men who had undergone an ACL reconstruction 6-40 months earlier and who, after 6-40 months after surgery, were evaluated with validated strength tests and self-assessment outcome measures.Results: At 12 months after surgery 56 % of the subjects had returned to their pre-injury sport. If the criteria were set higher ?back to the same- or a higher level? 14 % had returned.

Motion mot depression. En litteraturstudie om fysisk aktivitet somhälsofrämjande intervention för personer med depression

The purpose of this study is to investigate the effect of physical activity for people suffering from depression and which nursing interventions nurses can do to make this patients start to exercise. The method used, is a review of articles from Ci-nahl, Cochrane, Elin, PsycInfo, Pubmed and Science Direct, which were analyzed according to Polit och Hunglers criteria for scientific research. The result from the nine studies shows that physical activity has an antidepressive and anxiety reduc-ing effect. Interventions emerged is supporting, encouraging, activating and teach-ing about physical activity as health-promoting measure. Conclusion: Nurses can as an intervention introduce exercise as complementary treatment for people suffering from depression.

Kortsiktig fosforeffekt av avloppsslam : krukförsök i växthus där järn-, aluminium- respektive kalkfällt slam använts som fosforgödselmedel

The short term effect of phosphorus in sewage sludge was investigated to establish howmuch of this a farmer can grant him- or herself, if using sewage sludge as a phosphorusfertilizer. Possible differences in plant availability between sludge phosphorus precipitatedby iron, aluminum or calcium integrations were studied in a sandy soil at two pH levels.The sludges were analyzed using pot and incubation trials. As the intention was to investigategrowth limitation due to phosphorus deficiency, a soil with low phosphorus supplywas chosen as well as a low phosphorus application rate. Sludge corresponding to 12kg phosphorus per hectare was applied. Treatments fertilized by sludge were compared totreatments where 0, 6 and 12 kg phosphorus per hectare from mineral fertilizer was applied.Every treatment was replicated six times.

Varierad kaliumgödsling i potatis : en fältstudie i Hedemora

Variation in tuber quality within a single field was one of the motives for a pilot study in Halland, in south-western Sweden conducted during 2002. Quality problems in potatoes have been increasing due to the aggregation of several small fields with different land use history into larger farm units, which are heterogeneous in soil properties and fertility. The study in Halland indicated that both the uniformity and the mean size of tubers may increase from site-specific K fertilization, whereas total yields may be unaffected. The results from this pilot-study with site-specific fertilization showed that tubers reached a more uniform quality and gave a more uniform mean size, while the total yield wasn't affected at all. Site-specific K-fertilization has been applied for some years in Halland with good results. The aim of this study was to test this technique in another potato growing area.

"Den bästa motionen är den som blir av"Distriktssköterskans upplevelser i rollen som FAR-förskrivare

AbstractIntroduction: The condition of human health and its lifestyle has become a great questioner towards the public healthcare of our country. Despite the recommendations of at least 30 minutes physical exercise per day, many individuals of our society do not get the recommended amount of physical activity.  To improve the situation a method called ?Fysisk Aktivitet på Recept, FAR (Physical Activity on Recipe). This means that licensed health- and medical staff, as district nurses are able to write prescriptions on physical activity to patients.Purpose: Was to highlight the district nurse?s experience in the role of the FAR-prescribers.Method: The study was conducted using qualitative method.

Sjung i kör och håll dig frisk! En studie om hur körsång kan påverka körsångares emotionella och fysiska hälsa

Choir singing is one of the most popular national movements in Sweden but the knowledge of the meaning of this activity for health and well being from the choir singers? own experiences is limited. The purpose of this study was therefore to develop useful knowledge about the meaning of choir singing for participating persons from a health perspective. The data was collected through qualitative interviews with six different choir singers and went after that through a comprehensive analysis which resulted in four main categories: an oasis in the existence; possibilities of meetings and solidarity; goals and musical development; and physical and emotional well-being. The results showed that the choir activity represents a place where the singers can escape the demands and the stress factors of everyday life and where they get the opportunity of meaningful relations with other people.
