Kvalitetssäkring av markberednings- och planteringsuppföljning hos SCA Skog AB Jämtlands skogsförvaltning :

Quality assurance means to systematically work for better understanding of the customers needs, demands and expectations. The goal for this study was to investigate how quality can be assured in the job follow up that is made by forestry contractors after soil scarification and planting. The study consisted of a description over the current follow up process at SCA forest AB Jämtlands forest administration, analysis of current follow up situation and an investigation of follow up process made by contractors in other line of business. The first step was a statistical comparison where the own follow up made by contractors were compared with follow up made by SCA them selves over 100 stands. Two soil scarification contractors and two planting contractors carried out the silvicultural measures. The results showed that significant differences between a number of quality factors measured, for example number of approved plants or approved scarification points, average score on stand and number of totally planted plants.

Överlevnad, tillväxt och skador i planteringar av sitkagran (Picea sitchensis) efter stormen Gudrun

Sitka spruce (Picea sitchensis (Bong.) Carr) is just like Norway spruce (Picea abies) a species in thegenus picea. The natural range of Sitka spruce is a narrow strip along the west coast of North America. Itis the most coastal of all picea species, and very dependent on the mild and humid climate along thepacific coast.Sitka spruce has been grown a long time in the countries around the North Sea, particularly in GreatBritain where it currently is the most important species in British forestry. Sitka spruce has not beenplanted in Swedish forests to any large extent before the storm Gudrun in 2005. Several studies indicatethat the production of wood biomass is higher for Sitka spruce compared to Norway spruce.

Identifiering av områden med risk för fosforförluster genom ytavrinning : metodutveckling med GIS

The eutrophication of lakes and seas with the algal bloom and deficiency inoxygen that follow, has been given priority by the Swedish government as oneof 16 environmental objectives. The purpose of this project was to develop a toolbased on a simple model, limited amount of data and geographic informationsystem (GIS) to identify areas with risk for phosphorus losses due to surfacerunoff. This tool can act as a decision support to decide where appropriatemeasures should be applied with the aim of reducing phosphorus losses and bythat the eutrophication.The method that has been used is a combination of two models, one calculatingthe potential erosion while the other one identifies areas of erosion (net erosion)or deposition. This ability is of great importance because potential erosionshould be calculated on areas with net erosion. Areas with high potential erosionhave an increased risk for phosphorus losses due to surface runoff.The potential erosion was calculated based on factors which describe how topography(LS), land use (C), soil type (K) and precipitation (R) effect the erosion.All of them have been modified to a greater or lesser extent.

Filialer - ur ett borgenärsperspektiv

Den inre marknaden inom europeiska unionens gränser innebär många möjligheter för dess medborgare och företag. Som medborgare kan man flytta till ett annat land inom EU för att t.ex. studera eller arbeta. Som företag kan man för att expandera verksamheten välja att etablera sig eller sälja sina varor eller tjänster i ett annat EU-land. Den inre marknaden fungerar oftast väl, men naturligtvis kan problem ibland uppstå med tolkningen av gällande regler.

Behandling av konfliktbestånd - problem och möjligheter :

Overdue cleanings have for a long time been an important topic of discussion within the forestry sector. When stands that have not been pre-commercially thinned are reaching the level of commercial thinning, many problems occur in terms of decision-making and economical outcomes. These types of stands are commonly known as conflict-stands. The work was carried out partly as an interview survey towards representatives from the forest sector and the energy sector, partly as a case study of conflict-stands situated in Böksholm, north of Växjö and in Tönnersjö east of Halmstad. The criteria for the studied stands were that they had to be dominated by Norway spruce and be in a severe status of ?conflict?. The aim of the interview was to get an overview of the situation today, and also analyse trends in terms of conflict stands.

Att säkerställa rätten att nyttja utrymme/anläggning i annans fasta egendom - exemplet Trafikverket

A property is owned with ownership which in turn may be granted limited rights to acquire the use of land or space in another's property. Tenancies and easements are the most common limited rights. Trafikverket has a range of different rights that are linked to its properties. There are rights that work in favour of Trafikverket?s property as well as against them.

Beijers Park i "Parkernas Stad" : 125 års parkhistoria på Kirseberg i Malmö

To perform a historical record of Beijers Park's development to date is about securing the tracks back in time. The historical record about the park tells not only the history of the park but the city, district, local residents and art of gardening. As the historical story is documented the necessary base for establishment of any care plans in the future and the base for cultural and historical value the park is made. Beijers park can in such work be treated alone or as part of the context of parks that were built during the same era in Malmö's history.Beijers park origin from the era of the late 1800s, when the entire green structure in Malmö changed. The park area today covers 12 hectares and is located in the district Kirseberg.

Fjällfåglar : En jämförande studie från dal till topp i ett nordligt och sydligt svenskt fjäll

Title: Mountain birds ? a comparative study from valley to mountaintop in a northern and southern Swedish fjeld  Author: Kristian Zackrisson Abstract Main aim in this study was to increase the knowledge about birds in the Swedish mountain area. Three questions were asked: 1) Which bird species can be found during the breeding season along a low mountain slope from a forested valley to a mountaintop with bare mountain environment? 2) Do the number of species and individuals differ in different elevation zones? 3) Is the composition of bird species along a low mountain slope the same in the Kebnekaise mountains inLaplandand the Grövelsjön mountains in Dalarna? Bird census in two study sites located in the Kebnekaise mountains and the Grövelsjön mountains and subsequent analysis of the results from the bird census was the main parts in this study. Totally 20 bird species were found along a low mountain slope in the Kebnekaise mountains.

Grönstrukturplanering i det skånska slättlandskapet?

The ongoing change that characterizes the landscape as a result of the development of the society as a wholeis the basis for this thesis. Even though the Scanian landscape still is dominated by arable land, other valuessuch as biological diversity, cultural heritage and economical aspects, has all been ascribed the landscape asmore and more important factors and in some respects, compete with the farming industry about the right tothe landscape. Our demand of more and more space, will of course also affect the landscape. Huge amountof land are used to build external malls and single-family houses, which gives rise to an increasing need foran extended transport system that also is land consuming.It all comes down to: how the municipalities deal with non built areas - the green structure. Do themunicipalities have separate programs describing their vision and objectives concerning the green structure?Literature studies, an inventory made of the municipality programs in the west and south west of Scaniaand interviews with employees at the municipalities clarifies the use of the green structure concept, both intheory and in practice.The green structure concept seems to be derived from the environmental debate.

Fältskiktsarter i naturlika planteringar : vilka råd kan ekologer ge?

This paper appeals to professionals working with green questions. It intends to create a discussion about which plant species that can be established in a fieldlayer of a naturelike planting on fertile agricultural land. To initiate the essay, a studie of which values that can be connected with an establishment of a fieldlayer was performed . A part of Tor Nitzelius Park in Alnarp, a so called naturlike planting on fertile agricultural land, was used as a model for the choice of species. With the aid of soil values, photos and a list of current species, interviews with four ecologists were performed.

Komparativ studie av de nordiska ländernas energiprestandakrav vid nybyggnation av bostäder: En studie av byggregler och energiklassificeringssytem

I detta examensarbete görs en jämförelse mellan de Nordiska ländernas energikrav och klassificeringssystem för flerbostäder. Syftet är att utreda hur de olika nationella kraven styr i respektive land, och om det är möjligt att jämföra ländernas energiprestandakrav på ett rättvist sätt.Europaparlamentet har tillsammans med Europeiska unionens råd antagit direktiv om byggnaders energiprestanda som anger vilka mål som medlemsländerna ska uppnå. Syftet är att minska utsläpp av växthusgaser, öka andelen förnybar energi och skapa högre energieffektivitet. Dock är det upp till varje enskilt land att bestämma hur de ska klara målen, vilket gör att landets byggnormer och egen lagstiftning påverkar dess implementering. Därmed ser ländernas energikrav väldigt olika ut, trots att de är baserade på samma EU direktiv.

Fosforläckage från växtodling - orsaker och ågärder :

Phosphorus is essential to all plants and is taken up from the soil as the ion H2PO4 - (and to some extent HPO42-). Plant availability depends on, among other factors, the soil pH. In order to provide for plant available phosphorus, it is applied as mineral fertilizers and farmyard manure. However, that causes phosphorus leaching from arable land to surrounding surface waters and lakes and contributes to the eutrofication. There are three types of soils in Sweden that are at higher risk of contributing to phosphorus leakage.

Kortare avbrott för vistelse i Sverige och tredje land : Skatteverkets ställningstagande i förhållande till legalitetsprincipen

För att medges skattebefrielse enligt sexmånaders- och ettårsregeln får inte den skattskyldige på grund av semester, tjänsteuppdrag, eller liknande vistats i Sverige mer än sex dagar för varje hel månad som anställningen varar, eller totalt 72 dagar under samma anställningsår. Lagtexten uppställer således en begränsning avseende antalet vistelsedagar i Sverige, men vistelser i tredje land är inte begränsade i lagen.Skatteverket har dock lämnat ett ställningstagande enligt vilket den skattskyldige inte får vistas mer än 96 dagar per anställningsår eller åtta dagar per månad sammanlagt i Sverige och tredje land för att medges skattebefrielse enligt sexmånaders- och ettårsregeln. Ställningstagandet har ifrågasatts då det begränsar individers möjlighet att medges skattebefrielse enligt reglerna. Mot den bakgrunden syftar uppsatsen till att analysera om Skatteverket har stöd enligt legalitetsprincipen för ställningstagandet. Enligt legalitetsprincipen får ett ställningstagandes materiella innehåll inte uppställa nya rekvisit för tillämpning av lagregler, eller utan stöd av gällande rätt förorda en omotiverat snäv tolkning av rättsregler. Uppsatsens analys visar att ställningstagandets materiella innehåll inte är förenlig med gällande rätt vad gäller sexmånadersregeln.

Indirekta effekter på marklavars abundans och diversitet vid ökad kvävehalt i marken : en jämförelse mellan opåverkad och lågintensivt brukad mark

Lichens are adapted to bright and sparse forests on oligotrophic ground. Due to a slow growth rate and high light demand lichens will suffer from competition in eutrophic environments. Therefore, lichens have disappeared from managed forests where the forest industry has increased the productivity. A reduced abundance of lichens will affect both biodiversity of the forest and the reindeer winter graze lands. It is important to understand how and for how long fertilization affects the abundance and diversity of lichens in order to protect lichen rich ecosystems. We have registered the biomass and number of lichen species in eight plots (four nitrogen rich and four nitrogen deficient) and compared fertilized Sami settlements with their oligotrophic surroundings in the nature reserves of Tjeggelvas.

Hur upplevs hemkomsten? : Vad innebär det för individen att flytta tillbaks till Sverige efter en utlandsstationering?

Vi har i denna studie undersökt hur repatriater upplever sin hemkomst tillbaka till Sverige efter några års tjänst och bosättning i ett främmande land. Vi har framför allt studerat hur de upplever responsen och bemötandet från hemma-organisationen. Har hemmaorganisationen tagit tillvara på de nyvunna kunskaperna, erfarenheterna och kontakterna från tiden utomlands? En stor del av fokusen ligger på eventuellt upplevda omvända kulturchockar. Studien grundar sig på fem kvalitativa intervjuer med män från tre olika multinationella företag.
