Flygbildsanalys av trädskiktets status efter brand : en metodstudie

During the past years fire has been identified as an important factor for nature conservation in the forest landscape. To accurately quantify the size of a burnt area is obviously important, but also to quantify the degree of fire damage to the tree canopy. Such data are important for assessing the conservation value, and to support planning and management of the burned area in the future. I have examined how to estimate the status of tree crowns after fire from interpretation of aerial photographs. This is possible because fire changes the structure of tree crowns and this influences the colours in aerial photographs by spectral reflection. Included in the study are four areas, three of which burned in 2005 and one in 2006.

Förekomsten av sura sulfatjordar i Mälardalen : -en pilotstudie utförd åt SGU

Acid sulphate soils is a wide spread problem along the northern coast of Sweden. This is causing great damage through low pH and leaching of metals out into the streams. These soils are estimated to be found in several places in Sweden but also in many other areas in the world. One of these areas in Sweden that are believed to contain these sediments is Mälardalen. The purpose of this study is to evaluate the extension of the acid sulphate soils in this area.

Konsumentbeteende vid köp av färsk fisk : en kvalitativ studie för utveckling av ett produktkoncept hos ICA

Health and convenience trends dominate the food industry and retailing business of today. The health consciousness is spreading while appealing product attributes concerning taste and packaging also are increasingly important. At the same time, the competition is growing fierce in the Swedish market with hard discount formats and niche concepts who also are trying to provide the market with perishables. Therefore, the pressure to lower prices is increasing making economies of scale and rationalization progressively more important. In 2004, ICA launched private label meat packaged in a modified atmosphere. Consequently, many stores went from in-store cutting-up and packaging to selling centrally packaged and distributed meat. ICA is now developing a concept with fresh fish in modified atmosphere packages and needs to increase the knowledge about the market and the consumer.

Att återställa en naturlig ordning : skogshistoria och restaureringsbränning i Långsidbergets naturreservat

During the late 1800s fire suppression became increasingly effective in northern Sweden which led to decreased areas of fire-disturbed woodland and successive changes in the structure of forests. In the long run this can pose a serious threat to fire-dependent and fire-favored species. Today some fire-prone forest reserves are burned as a nature conservation act. Often partial cuttings are made before burning, with somewhat different motives. The purpose of the study in Långsidberget nature reserve was to give a general picture of forest history and its affect on today?s forest condition, and to show how partial cuttings affect burning conditions and results. Långsidberget is located close to areas that were colonized during the Middle Ages.

Indelning av trakter inför gallring på Holmen Skog : en utvärdering av svårigheter och möjligheter

A common goal in practical forest management is to maximize the yield, measured in economical terms. When a forest stand is thinned a so called inoptimality loss can arise due to non-optimal decisions. This means that the selected management schedule results in a lower net present value than the optimal one which lowers the profitability for the forest owner. Holmen Skog uses the term tract which means an aggregation of stands made before a management action. A tract should be delineated in different tract parts in connection with pre-thinning planning if there is different bearing capacity within the tract, different thinning grades should be used or if the tract contains a weaker part that should not be thinned.

GIS och statistik vid dräneringsområdesvis kväveläckagebeskrivning i Halland

The last decades have shown increased nitrogen leeching from soil to water recipients. This is inSweden mainly due to over-manuring of agriculture land, effectivization of drainage systems and thedeclining extent of wetlands. The accumulated amount of nitrogen in water doesn?t only make itunsuitable for use by humans and cattle, but also decreases the biological diversity as well as negativelyaffect tourism and fish industry. In the most severe cases shallow maritime grounds can be completelydepleted of oxygen due to decomposition of the increased amount algae and plankton growth.This study have the aim to describe and quantify the nitrogen leeching from the Genevad drainagebasin, located in southern Halland, Sweden.

Personalredovisningens omfattning - en dokumentstudie av bolag på Stockholms fondbörs

Den samhällsrelaterade redovisningen har utvecklats under de senaste åren och fått en allt större betydelse för företagen och dess intressenter. Att utvecklingen går mot mer kunskapsintensiva verksamheter borde öka betydelsen av personalredovisning, vilken är en del av den samhällsrelaterade redovisningen. Det bör ligga i företagens intresse att redovisa sin personalrelaterade information med tanke på att det är en allt viktigare tillgång. Med anledning av att det endast finns ett fåtal regler för hur personalen skall redovisas, väljer företagen det sätt som passar repektive företag bäst. Syftet med undersökningen är att klargöra för i vilken omfattning svenska börsnoterade företag redovisar sin personalrelaterade information, om det skiljer sig mellan företagen beroende av branschtillhörighet, storlek eller någon annan faktor.

Attityder hos lastbilsförare gällande mat i samband med långa, korta -respektive blandade transportsträckor

Martinez, A (2011). Attityder hos lastbilsförare gällande mat i samband med långa -respektive korta transportsträckor. Akademin för hälsa och arbetsliv, Högskolan i Gävle. AbstractBackground: The profession as a lorry driver is in many aspects very risky. Factors such as time directive, poor diet and shift work characterize the profession and puts drivers' health at risk. Current research shows that the vast majority of lorry drivers are overweight, suffer from high stress related to work and have on average a very low consumption of fruits and vegetables.

With a few liters of clean drinking water : a Cost Benefit Analysis of the socio-economic effects from implementing new clean drinking water technologies in rural India

In 2010, Airwatergreen AB started testing their new technology, the Airwaterwell, an atmospherical water generator of their own design that is running on solar heat, with a production capacity of three litres of water per day and m2. The purpose was to focus on foreign aid organizations as main purchasers for project investments towards rural communities in developing countries that suffer from lack of, or compromised quality of drinking water. In order to further understand if this technology would bring a positive impact in the developing countries, the company contacted the Swedish University of Agriculture for a socio-economic study of the Airwaterwells? potential. The authors elected Cost benefit analysis as the appropriate method for conducting the study and India became the study region because of its many problems with water related issues such as diseases as well as insufficient water supply for households. The regions that this study is based on are Gujarat, Haryana and Uttar Pradesh given their differences in income, health situation and poverty rate.

Etablering i Australien - En komparativ fallstudie om anpassning av marknadsmixen och identifiering av framgångsfaktorer hos tre svenska företag

Globalization has stimulated the free markets and has made possible for Swedish companiesto expand internationally. Some markets have been deemed attractive and companies havechosen to enter them. The decisions concerning internationalization and marketing havedetermined the success of the companies on the new market. Therefore, several elementsbecome important: the motives behind the new market entry, the local marketcharacteristics and the adaptation of the four components of the marketing mix ? product,price, place and promotion.The purpose of this thesis is to study how three Swedish companies adapt their marketingmix to the local conditions in Australia and identifies success factors in order to help othercompanies considering a market entry.

Rörelsemönster och golvrenhet på två olika slags spaltgolv i lösdrift för mjölkkor :

About 80 % of all Swedish dairy cows are kept in tie-stalls, but loose housing is increasing, probably because it is more profitable for the farmer. The design of the floors is of cruicial importance to the cows well-being. Traditionally, the most common type of floor in the alleys of a cubicle system still is a slatted manure-draining floor made of concrete. The typical Swedish design has 125-mm slats and 40-mm slots, maximally. With too wide slots, there is an increased risk of injuries to the claws when the cow makes a hasty move.

Shelter use of horses during Swedish summer in relation to weather conditions and insect abundance

Outdoor housing of horses? best fulfils the horses? need for physical activity and it is an alternative to the more cost and energy demanding indoor housing in stables. Furthermore, if outdoor housed horses have access to shelter they can generally cope well with adverse weather conditions such as high or low ambient temperature, heavy rain or strong winds. In this study, the daytime shelter-seeking behaviour of three groups of horses housed outdoors was studied during the summer. The aim was to evaluate whether shelter use is related to weather variables (e.g., ambient temperature and wind speed) and insect harassment. The shelter-seeking behaviour was studied for three different groups of horses: Group 1) eight individually housed horses in paddocks that had access to three different shelter types (C: closed on three sides with roof, R: open on three sides with roof, W: closed on three sides without roof), Group 2) 25 group housed mares with foals on pasture with access to shelters C, and Group 3) ten mares without foals on pasture without access to shelter. Each group was studied for eight days.

The effects of mother trees and site conditions on the distribution of natural regeneration establishment in a Bornean rainforest disturbed by logging and fire

In the tropics, logging and wild fire can result in degraded secondary forests with lower biodiversity than in the natural forest. One way to limit forest degradation is to rehabilitate the present large areas of secondary forests. However, there is a lack of knowledge concerning the ecology of tropical tree species and further studies would be advantageous for future rehabilitation efforts of degraded rainforest. The objective of this study was to investigate how mother trees in secondary forest and different site factors affect the abundance and spatial distribution of natural regeneration of non-pioneer tree species in a tropical rainforest in Sabah, Malaysia. The study took place in the INIKEA Forest Rehabilitation Project area, which suffered from wild fire in 1983 and has been selectively logged over both before and after the fire. Natural regeneration and site variables were inventoried in plots, while mother trees were inventoried in the whole survey area.

Skam - ett sår på insidan.

Vi har valt att belysa skam i den somatiska vården, då vi upplever att det sällan talas om skam som är förknippad med somatisk sjukdom. För att skapa balans i tillvaron och stärka välbefinnandet, den fysiska och psykiska hälsan bör patienten mötas med respekt och värdighet. Sjuksköterskan skall enligt ICN lindra lidande, återställa och främja hälsa, förebygga sjukdom vara öppen inför andra människors värderingar och upprätthålla en miljö där det värnas om mänskliga rättigheter. Vård skall enligt HSL ges med respekt och på lika villkor och den enskilda människans värdighet skall beaktas. Syftet med studien var att belysa patienters beskrivningar av företeelser som leder till skam.

Användning av satellitdata för lokalisering av skogsområden där lövröjning bedöms angelägen : en analys av användbarheten med fjärranalys som hjälpmedel till röjningsrådgivning

This master thesis project is a part of a project called ?Järboprojektet? at the regional board of forestry, the district of Gästrikland. The project will give answers to questions regarding if an analysis of satellite images can be used to contact and inform landowners of the located areas where precommercial thinning is useful. The whole project is a part of the National Board of Forestrys IT-stake where the analysis of satellite images will, at the latitudes possible, be adapted to each district in purpose to identify these areas in need of precommercial thinning. This master thesis project is based on a field inventory of identified objects where precommercial thinning is useful.
