Old hollow trees of oak contain a large amount of wood mould. Unfortunately, these trees have in the last century been greatly reduced in numbers. It has resulted in that species that depend on these habitats, saproxylic species, have become at risk to decrease in numbers or die out regionally. Previous studies have shown that the volume of wood mould is an important factor for occurrence and population size of saproxylic organisms. The aim of the present study was to examine how the volume of wood mould varies among ash (Fraxinus excelsior), lime (Tilia sp.), maple (Acer platanoides), aspen (Populus tremula) and oak (Quercus robur).

The interest in harvesting wood fuel in conflict stands has grown in recent years as a consequence of the increased demand for biofuel. Conflict stands are young forests that have not been cleaned and have a large number of stems ha-1with a great height and diameter distribution. This means that traditional field measurements in conflict stands are difficult and very time consuming. Therefore, the forestry sector is in need of new, more efficient inventory methods. In this study, the Lidar data from Lantmäteriet?s (the Swedish mapping, cadastral and land registration authorities) new national height model was used in combination with plots from the Swedish national forest inventory from 2009 to create functions for; height, volume, diameter and number of stems.

The agriculture throughout the world is becoming increasingly deregulated and this has affected the prices of raw materials to fluctuate at a higher degree than earlier. This in turn has made it interesting and in some cases even necessary for the trader as well as the producer to gain knowledge about the trade instruments available to ensure a good enough price for their produced goods. This study encompasses a number of ways to trade grain and oil plants in order to clarify what differences there are in the several contracts that exist in the present situation, economical as well as practical. The various trade instruments available to the producers on the Swedish market are described in the theoretical part of this study. The study also contains a simple arithmetic example, based on historical prices collected from grain traders and trading floors, in order to point out the differences in the economical outcomes depending on the business strategy used to sell the produced goods. The study shows the importance, as a producer, of being able to use and take advantage of the different trading instruments at hand to monitor and exploit the shifts in the market. From an economical point of view it is not enough to just excel at farming but knowledge about the market functions and the trade instruments at hand is also required to be able to secure a good enough price for your goods.

I uppsatsen ifrågasätts den svenska lagstiftningen gällande tvångslikvidation på grund av kapitalbrist enligt 25:13-20a ABL. Lagstiftningen utreds utifrån det medansvar som kan åläggas styrelsen vid kritisk kapitalbrist och de krav på agerande från styrelsens sida som lagstiftningen ställer. Uppsatsen fokuserar på hur lagstiftningen påverkar borgenärsskyddet och borgenärernas intresse av att få sina fordringar betalda. Som alternativ till den svenska lagstiftningen presenteras den engelska regleringen som kontrollerar styrelsens agerande vid kapitalbrist i aktiebolag, section 214 IA, ?wrongful trading?, samt den engelska ?common law?.

The aim of this thesis is to clarify the affect that preferential and regional trade agreements have on the World Trade Organization (WTO), as being establisher of the international trading regime. The essay is an explanatory literature study, which strives to answer the following questions:Are regional and preferential trade agreements a threat or a complement to the WTO?Is an undermining of the MFN principle weakening the WTO?How do regional trade agreements made by the EU affect the future of the WTO?The empirical material is to be analyzed using an explanatory framework, which is based on neo-liberal instutionalism, theories on regime changes and a game theoretical approach, using prisoner?s dilemma. I will employ the EU-ACP relation, the Cotonou agreement to exemplify how an agreement of this kind can have an influence on multilateral trade. The result shows that preferential agreements do have an impact on the WTO, one that is fairly negative in scope.

FSC (Forest Stewardship Council) is the major form of certification system in Swedish forestry today and its more than 11 million hectares are covering almost half of the total productive forest area in the country. Its regulations prescribe that at least 10 wind firm trees should be left behind after every clear cutting operation. This study have taken place on 30 recently clearcut objects in Bergslagen, Sweden, were an inventory of the standing stock have been made. The research shows that, with 90 % security, the retained trees together contain 9-13 m3sk per hectare. Pine is the dominant tree and it covers more than half the numbers of retained trees and its volume cover 65 % of the retained trees total volume. Spruce is on second place with 30 % of the retained trees, but only 21 % of the standing stock.

The purpose of this study is to assess the state of health of the individuals living in Löddeköpinge during the middle ages, whose remains were excavated by Chintio, H., 1975-80. The location is thought to have been a trading community that ceased to flourish towards the end of the Viking age. The main focus of the essay is to examine the occurrence of osteoarthritis (sv. artros), trauma, and analysis of stature, in order to understand population health during this time period. Osteoarthritis has never been researched in Löddeköpinge and the analysis showed that, of the 60 skeletons examined, 68,3% demonstrated some change in the skeletal joints, which is much higher than in the comparative material obtained from Lund and Sigtuna.

Denna rapport är ett examensarbete på C-nivå som görs i sammarbete med teknikkonsulten Ramböll. Det vanligaste sättet att ventilera en byggnad idag är med så kallad CAV-ventilation (Constant Air Volume). Denna metod bygger på att ett luftflöde bestäms för rummet och upprätthålls med konstant flöde. En annan metod är så kallad VAV (Variable Air Volume) som bygger på att flödet varierar efter behovet. Anledningen till varför man väljer VAV istället för CAV är att med CAV finns det ofta en stor risk att man överventilerar ett rum eller byggnad, just på grund av att flödet är konstant. Problemet med VAV är att det är en högre investeringskostnad än för CAV så metoden lämpar sig bara där energibesparingen är så stor så den täcker mellanskillnaden i pris.

The purpose with this study is to find out how much dead wood we can expect us to find in a Russian reference river and compare with studies from Swedish streams. Dead wood are an important structure for the biodiversity in forest streams, studies have shown that population of trout can increase with up to 300 % when the amount of dead wood are increasing from 0 to 8 ? 16 LWD (Large woody debris)/100 m2. Dead wood are also an important structure for the stream character, formations of dams and pools which are important habitats and reproduction areas for salmon and brown trout. The study where taken place in tributaries to the Russian river Varzuga in the North West part of Russia outside Murmansk. Varzuga has low impact of human activity and is considered to be a reference river to rivers in northern Sweden.

Sweden is a country with few native tree species. According to Govt. 2007/08: 108, exotic tree species may be seen as an opportunity to increase the growth of tree volume in Sweden. Potential areas where explored In this work for cultivation with Pinus contorta var. latifolia Engelm., Larix sukaczewii Dylis, Abies lasiocarpa (Hook.) Nutt., Populus × wettsteinii Hämet-Ahti (tremula x tremuloides) and Picea mariana (Mill.) Britton et.al.

This study investigates how the concept of Social Responsible Investment (SRI) can be applied to futures trading. More specifically, this study examines the possibility of creating a SRI-product for an investor, active in futures investments within commodities, energies and stock indices, and the content of such a product is suggested. We conducted a qualitative study, based on a number of interviews. The study suggests that investments in futures of specific assets are to be equated with investments directly in the underlying assets from a SRI point of view. Therefore, we analyzed the underlying assets of futures traded commodities, energies and stock indices, and used social screening, together with specific screening criteria, for the analysis.

Piles of deadwood are often retained in forests after management to support the biodiversity ofsaproxylic organisms which depend on deadwood to survive. Any knowledge about the crucial role ofpiles as suitable habitat of saproxylic organisms compared to single distributed deadwood objects thatare around the piles would help conservation actors to motivate more forest owners to supportsaproxylic organisms during their management. Therefore to give facts to this the saproxylic fauna ofdifferent pile positions (up and low) was studied and compared to distributed deadwood samplesaround each pile. Our study was focused on saproxylic beetles. Some other parameters such asdiameter, deadwood volume, pile volume and decay stage were assessed to define any effect.

At the beginning of the 1970´s forestry feared an imbalance in the future wood supply. Because of this anticipated "timber slump" forest companies undertook a variety of measures to counter this. One of these measures was the introduction of exotic tree species. The choice finally ended up with lodgepole pines which were considered a fast growing tree species compared to our native tree species. Theambition for the new lodgepole pine stands were to run these with rotation periods of between 40-60 years, thus smoothing out the ?timber slump? that was anticipated.

This thesis rewievs present day research on the settlement of Östra Aros in central Sweden. The thesis deals with the period from late Iron age to about 1270 AD, when the Swedish archdiocese moved to the already existing early-medieval settlement of Östra Aros, thus becoming the medieval town of Uppsala. The basis of the thesis is the study of a variety of source materials, such as artefact studies, runestones, topography and the prehistoric and early medieval hinterland. The thesis centers on archaeological excavation data and dating of settlement structures, particularly focusing on the settlements establishment. Through a critical review of primarily the written record and the archaeological data, the settlements characteristics and functions are discussed, emphasising when and if the settlement could be described as a town, central- or trading place..
