There are five endemic populations of migratory Atlantic salmon (Salmo salar, Salmonidae) and brown trout (Salmo trutta, Salmonidae) remaining in Lake Vänern, whereof two are salmon and three are trout. There is one population of each species in Klarälven, also one of each in Gullspångsälven and there is a population of trout still remaining in Tidan River. Since the beginning of the 20th century endemic populations of salmon and trout have either vanished or declined dramatically due to the construction of hydropower in the rivers around the lake, and still today the future of the remaining populations remains uncertain. To manage salmonid fishes effectively more knowledge of their ecology throughout their different life-stages is needed. A large part of the Lake Vänern salmonoids lives are spent in the lake, where a mayor mortality factor is recreational fishing, especially angling.

Problem Discussion: Today the banks manage three central products: mutual funds, mortgages and bank accounts. Banks have authority and credibility, the services and the products they offer and sell can sometimes be difficult to understand. Customers are offered a large number of investment options with varying risk profiles. These developments have created an increasing need for knowledge and information among customers. The financial advice that the financial firms provides, remains a very important activity from a customer view.

Det finns ljud som är på väg att försvinna i takt med teknologins utveckling. Dagens ungdomar har aldrig hört ljud från den äldre teknologin, som den äldre generationen har fått växa upp med såsom skrivmaskinen, modemet m.m. Dessa produkter gav ifrån sig ett speciellt ljud som numera inte hörs lika mycket idag. Men vad händer när tekniken utvecklas till den grad att ljud blir en säkerhetsfråga? Förutom teknikljud finns det ljud från förhistoriska och nyligen utdöda djur som forskare har lyckats återskapa genom studier av kvarlevornas anatomi.

Eutrophication of lakes and streams are nowadays a well known environmental problem and implies an enrichment of the nutrients phosphorus (P) and nitrogen (N). Phosphorus is considered to be the most important component for the growth of aquatic plants and leads in too large quantities to an intensification of growth. Phosphate (PO4) is the fraction of phosphorus that can easiest be taken up by plants and thus have the greatest impact on eutrophication. Increased plant growth in lakes and unfavorable conditions for aquatic animals are two examples of negative consequences. A significant portion of the increased nutrient supply to nearby water can be derived to phosphate leaching from agricultural areas, where private sewers and agriculture is two main sources.

The Swedish Welfare Act § 4 says that "Animals must be kept and cared for in a good environment for animals and in such a way that promotes their health and allow them to behave naturally." Pigs in the wild spend 80% of their waking hours walking around and rooting for food, eating and exploring their environment with its snout. Fattening pigs in commercial farms spend 80% lying doing nothing. A lactating sow is lying down most of her day, and only 10-20% of the body surface is in contact with the floor, so the pressure is high on these spots. Piglets lie down and paddle with their legs, with high liquid content in the tissues, several times an hour, to stimulate and massage the sow's udder. In the existing system, these individuals are held more often on floors that are anything but inviting to sleep on.

Combustion of fossil fuels is today the dominating source of energy. During combustion,carbon dioxide is formed. The carbon dioxide accumulates in the atmosphere,which raises the global average temperature on earth through the so called greenhouseeffect. The only way to reduce the emissions of carbon dioxide from combustionin a coal fired power plant is through carbon capture and storage (CCS).Post-combustion capture is a technology to separate carbon dioxide from the uegas after the combustion for efficient transport and storage. The steady state operationof coal fired power plants with post combustion capture has already beenthoroughly investigated on a pilot scale, however much work remains to investigatethe plants dynamic operation.

The Swedish exit tax legislation in Chapter 22. § 5 p. 4 IL states that businesses who change its tax residence to another Member State within the EES are taxed as having its assets sold at the time of the change of domicile. This legislation was declared incompatible with the freedom of establishment in case RÅ 2009 ref. 30 due to the fact that businesses who changed tax residence were treated worse than businesses that remained within the Member State of origin.

In the Swedish market, there is a wide selection of herbs as supplement to the horse´s feed. A trend today is that many companies are marketing herbal remedies with allegations of medical effects. If you want to sell the product for that purpose it must be verified and approved as drug or natural remedy by the Medical Products Agency. Some herbs may contain active substances. Nevertheless, only a few studies have been conducted on single herbs to investigate safe doses for horses.

Eutrophication of the Baltic Sea and Swedish lakes remains a major problem despite many years of effort to reduce the emissions of nutrients. One major source is waste water systems, especially private sewage systems. These sewages accounts for a very large share of nutrients per capita in comparison with citizens connected to larger sewage treatment plants. Norrtälje community has the greatest number of private sewage systems in Sweden. Discharges of nutrients, especially phosphorus, to the Baltic Sea from these sewage systems are significant.

Malmö Kommunala Bostadsbolag Fastighets AB owns and administrates Örtagården housing estate in Rosengård which is a characteristic million programme housing area. Örtagården is densely populated which naturally creates an environment that is exposed to wear and tear. The area is today undergoing a change where new proposals and strategies are to be designed for further development of the inner yards. MKB also wishes to develop the park area which is centrally situated in Örtagården. The purpose of this study was to make an analysis of the development of Örtagårdsparken from when it was planned and constructed up until the state it is in today.

AbstractThe use of standard agreements can hardly be overestimated in the society of today. The amount of standard agreements should barely decrease. One of the standard agreement?s main purposes, to make the concluding of the contract more effective, strongly agrees with the companies will to accomplish fast concluding of agreements using as small resources as possible A dispute that can arise in these contexts is that dissimilar standard agreements collide. Between nations this is called Battle of Forms.

A couple of hundred years ago half of the earth?s surface was covered by forest. Today, only half remains and every year an area the size of Nepal is disappearing. Deforestation, together with the burning of fossil fuels, is also one of the reasons for the increasing greenhouse effect. Another relatively unknown problem for the world?s forests is the trade with illegally harvested timber.

The agricultural sector accounts for about 13 percent of the total load of greenhouse gas emissions from Sweden (Swedish Environmental Protection Agency, 2007). The Swedish objective to reduce the greenhouse gas emissions with 40 percentage units to the year of 2020, based upon the year of 1990, might imply stricter regulations for Swedish farmers. A regulation or other forms of economic incentives is probably necessary to reduce the emissions originating from the agricultural sector. This study aims to investigate the economic and managerial impact on two agricultural firms with differing production system given that a constraint on green house gas emissions is introduced. Gases included in this study are carbon dioxide, methane and nitrous oxide.

The aim of this thesis is to investigate whether legal rights are upheld when wording and applying the postponement of payment of tax regulations of chapter 17 section 2 p. 2-3 of the payment of Tax Act. We also investigate how the wording of the regulations relate to the requirement of legal security.It has been questioned if the regulations concerning postponement of payment of tax are compatible with the requirement of legal security. Of course does not a taxpayer want to pay tax that he or she consider incorrect, and that has not been under trial by an impartial authority. If the request for postponement of payment of tax is rejected, the consequences for the taxpayer can lead to huge financial losses.

Urban trees have very little in common with trees on natural sites, such as forests or pastures. Trees in urban environments are often planted in packed soil and in small volumes. This can lead to decreased availability of water and oxygen, as well as deteriorated ability for the soil to store nutritional elements. Also above ground the tree usually have limited space in cities. Regulations on free height over roads and cycle tracks demands high stems at an early stage of their development.
