Nyckelbiotoper och kontinuitetsskog i Vilhelmina Kommun : ett landskapsperspektiv

Med nuvarande trend kommer snart all skog bortsett från de skyddade områdena att vara påverkade av trakthyggesbruk. Denna studie inom Vilhelmina kommun och Vilhelmina Model Forest visar hur skogslandskapet i sydöstra delen av Vilhelmina har påverkats sedan trakthyggesbruket infördes, med störst påverkan i den sydöstra delen och minst i den västra delen närmast fjällkedjan. Detta arbete har syftat till att analysera hur skogar som inte blivit brukade med trakthyggesbruk och nyckelbiotoper är fördelade geografiskt, och hur de sammanfaller geografiskt, inom ett stort landskapsavsnitt i den sydöstra delen av Vilhelmina kommun. Studien har också syftat till att visa om storleken på skogsområden med sammanhängande opåverkad skog har betydelse för antal och areal registrerade nyckelbiotoper och om det finns någon trend från sydöst till väst. Alla analyser för arbetet har skett i ArcGIS med hjälp av kartmaterial av registrerade nyckelbiotoper och kalavverkade skogar från Vilhelmina Model Forest. Resultatet visade att 63 % av arealen nyckelbiotop i den sydöstra delen av kommunen ligger i skog som inte blivit genomhuggen med trakthyggesbruk.

Att studera validerade mätinstrument : för att mäta barns oro inför dagoperation

Background: Anxiety with children before surgery is well known. From the 1950s there are various assessment instruments. Despite that most day surgery units offer preparation for children and parents, there are many children who exhibit a strong anxiety the day of surgery, which can lead to postoperative behavioral changes. Today the nurse estimates the anxiety of a child on personal experience and knowledge, forming the basis for estimation whether the child is in need of sedation or not. The purpose: of this study was to evaluate instruments that the nurse can use in measuring the degree of anxiety of children before fast clinical settings, such as day surgery.

Vad styr förekomsten av sälg och asp? : en studie av olika beståndstyper inom Hamra kronopark, Dalarna

Aspen (Populus tremula L.) and goat willow (Salix caprea L.) are two important tree species in the aspect of nature conservation. Due to the elimination of forest fires, a former negative attitude towards deciduous trees in forestry and a strong herbivore pressure, these tree species have been negatively affected during the last fifty years. The aim of this study was to investigate whether the occurrence of aspen and goat willow could be related to either human impact or to site properties, such as ground moisture and vegetation type. A side study included an inventory of a number of cyanobacterial tree lichens on aspen and goat willow in order to try to relate the occurrence of these lichens species to stand history and stand properties. The study was performed in Hamra State Forest in northern Dalarna. Nature reserves were compared with stands in managed areas.

Optimalt råvarulager för biobränsleföretaget :

This report was written as a final thesis within the Department of forest economics at the Swedish University of Agricultural Sciences as a completion of the M.SC Forestry programme. The aim of this study was to create a model that, with respect to given stock levels, temperature, fuel usage and fuel price, would identify the optimal levels for purchase of bio fuels, optimal levels of incineration of bio fuels and the sum of the present values of all costs. The model would be applicable for a larger district heating plant. Data regarding temperature were received from SMHI. Information considering fuel prices was taken from the Swedish Forest Agency and the facts about fuel usage were collected from a large district heating plant, located in the southwest of Sweden. For the temperature, a sinus curve was adapted to describe the temperature over a year.

Utvärdering av effekter hos deltagare i projektet Skogsbruk och vatten inom Landsbygdsprogrammet hos Skogsstyrelsen i Östergötland

Som skoglig sektorsmyndighet är det Skogsstyrelsens uppgift att omsätta regeringens skogspolitiska mål i praktiken. De behöver därför ha kunskap om deras arbete faktiskt ger effekter i skogsbruket. Ett verktyg för att undersöka effekter är utvärderingar. Genom en utvärdering kan Skogsstyrelsen se vilka effekterna är samt få ett underlag till att förändra och utveckla framtida projekt. Denna studie syftade till att utvärdera effekter hos deltagare avseende kunskapsinhämtning och användningsgrad samt deltagarnas upplevelse av vattenkvällarna i projektet Skogsbruk och vatten inom Landsbygdsprogrammet hos Skogsstyrelsen i Östergötland.

Anpassad skötsel - exempel på hyggesfritt skogsbruk i Mellannorrland :

Total protection is often the option chosen when protecting forests with high environmental values. An alternative to total protection is application of management regimes that do not interrupt continuity of tree cover. This study focuses mainly on continuous cover forestry (CCF) in forest stands already protected. All objects are situated in the county of Jämtland in northwest Sweden. The purpose of the study was to attain a greater knowledge about CCF practices.

Påverkas mosippa (Pulsatilla vernalis) negativt av igenväxning?

Pulsatilla vernalis is one of several endangered plant species that benefit from wildfires and small scale disturbance events that repel competing vegetation and create open patches in the vegetation cover. Previous studies argue that Pulsatilla vernalis is decreasing in numbers due to vegetation changes associated with the decrease in wildfires, forest grazing and changes in forest management. In this study, 17 populations of P. vernalis were inventoried in order to examine if soil and/or vegetation structures affect the population structure of P. vernalis (i.e.

Skogstillväxten ca 20 år efter plantering på Flakmossen : dikningens och gödslingens betydelse vid beskogning på en avslutad torvtäkt i Värmland

This study was performed in an afforestation experiment established 1982 on an abandoned peat harvesting area, Flakmossen, in the province of Värmland, SW Sweden. The experimen-tal design include planting with Scots pine (Pinus sylvestris), in combination with various drainage intensities (20, 30, and 40 m between ditches), and fertilizer doses 0, 100, and 200 g PK per seedling applied at the date of planting. The aim of this study was to achieve more knowledge about the conditions on afforestation of peat harvesting areas, especially regarding drainage intensity and fertilization requirements, by means of determining the stand growth and yield in the Flakmossen trial. The forest growth did not differ significantly between the drainage intensities tested when the same amount of phosphor and potassium fertilizer was added. Thus, shorter distances between ditches than 40 m can not be recommended. When no fertilization was carried out seedling survival was very low, and the growth of sur-vived seedlings was poor. The largest diameter and height growth were observed in the areas where the highest dose of phosphorus and potassium (200g/seedling) was given.

Flygburen laserskanning kopplat till skördarmätning för datainsamling till operativ planering :

The requirements for operative planning activities are increasing. The forest industry wants to gain better control over wood flow. A felling that is more market adjusted is desirable. However, this causes problems in the operative planning process because of the data collection methods used today. Data about timber assortments and data about the distribution of the tree diameter, etc., are often lacking. Airborne laser scanning is used to a greater extent than before for estimation of forest variables and should perhaps be used to the same extent in operative planning activities as well.

Fukthaltsförändringar för skogsbränsle : En jämförelse av torkförloppet i grönrisskotade och brunrisskotade vältor

In 1994 a new Forestry Act was accepted in Sweden. One of the aims of the law is to raise consideration forpreservation of biodiversity. Since the new law got accepted and some time has passed, there now lie someinterest in examining whether the law has been effective towards its purpose. Methods suitable for analysishave been examined during this study. The content of this pilot study is based around five parameters whichcan be used to validate the effects of the new law.

Konflikter och organisationer : En diskursanalytisk studie av två handböcker i konflikthantering

The situation that one can discern on the Swedish real estate market is that while there are several offices vacant, the need for apartments is high ? the vacancy rate for apartments is non-existent. According to the rebuilding of Skatteskrapan one will realise that the project requires a lot of money, even though it promotes the residential situation. The real estate owner experiences a risk in rebuilding real estates ? whether it will generate good yield or not.

Webb 2.0 i svensk B&I-utbildning

This thesis describes the introduction of Web 2.0 education into Swedish LIS education with emphasis on the driving forces and obstacles in the process. It also discusses the possibilities of estimating the appropriate time for the start of new educational courses introducing new technologies, when it is uncertain if the technologies in question will sustain for a long enough period of time to make the educational effort worthwhile. The data on the Web 2.0 education was collected during the spring of 2010 from the Web pages of the five LIS departments in Sweden, namely Borås, Lund, Umeå, Uppsala and Växjö, as well as by 10 interviews during November and December 2010 with two representatives from each LIS department..The key finding is that Web 2.0 is covered in Swedish LIS education and embracing both practical and theoretical issues. The main driving forces have been both the needs of the profession and an academic research interest. It is concluded that Rogers??S-curves? as described in ?Diffusion of Innovation? can be used as a tool in order to improve the understanding of when to introduce education in new technologies.

Förluster i olika ensileringssystem

In Sweden the climate makes it impossible to feed fresh herbage to cattle during many months of the year. During periods when preserved forage must be supplied it is important that this forage is stored in such a way that high quality is retained, both nutritionally and hygienically. Furthermore, it is essential that losses occurring when handling and storing the forage are kept as low as possible. This study compares storage in tower silos, bunker silos, big bags and bales,estimating dry matter losses as well as losses in metabolizable energy and crude protein that occur during storage. The results show that tower silos, bunker silos and big bags, the systems with the largest amount of forage and a long feed out period involve larger losses than bales, which are fed out immediately after being opened. As the feed out rate influences the losses, tower silos and bunker silos should be used during the period of the year when the feed out rate is as high as possible, i.e.

Landskapsideal : hur uppväxtens landskap formar individen

The landscape can be something that you rest your eyes on, something that goes quickly past outside the windscreen or the place for the daily work. To me, landscape is everything around us ? the city, the field and the forest. But what is landscape for you? What does the idea of the landscape stand for? How does our view of the landscape become influenced of the place where we grow up? And the differences between peoples different views of the landscape ? what does they depend on? My point of the view for this paper is that the landscape ideals mostly depend on the landscape where you grow up and that it depends less on the differences between the individuals. As a landscape architect the idea of the landscape is the essential. The more we learn, the more we realize how complex it is, but deep down we always have our own experiences and memories and that shapes our personalities.

Näraståendes upplevelse av förändringar av pragmatiska aspekter i samtalsinteraktion hos patienter med typisk parkinsonism

The purpose of this study was to examine if atypical Parkinsonism affectsthe pragmatic ability in conversational interaction. 15 persons close to individualswith atypical Parkinsonism answered a questionnaire, "Bedömning av förändring isamtalsinteraktion", estimating experienced change in interactive skills comparedto before the disease. The study also examined if perceived change correlates withdisease duration and if perceived change differs between types of atypicalParkinsonism. The results show that at group level the participants experiencechange in many aspects of conversational interaction, particularly regardingspeech, body communication, response latency, phrase length, word finding andability to understand. There was no correlation between perceived change anddisease duration.
