Kapitalstruktur : En jämförande studie mellan kapitalintensiva och kapitaltunna branscher
Uppsats behandlar företags kapitalstruktur d v s fördelning mellan främmande och eget kapital. Det finns teorier kring ämnet som menar att ett företags värde påverkas av sammansättningen mellan skulder och eget kapital. Detta föranledde vår problemformulering om att närbesläktade verksamheter uppvisar en likartad skuldsättning. Syftet var att jämföra skuldsätt-ningsgraden mellan kapitalintensiva branscher och kapitaltunna branscher. Utifrån detta ställdes vår hypotes upp om att kapitalkrävande branscherna fastighet och tunga maskiner har en högre skuldsättningsgrad än branscherna läkemedel och tjänster.
Invandrarkvinnor i Handels : Föreställningar om arbetskraftsinvandrade kvinnor i Handelsnytt 1961-1976
Invandrade kvinnor i Handels. Föreställningar om arbetskraftsinvandrade kvinnor i Handelsnytt 1961-1976. (Immigrant women in Handels. Conceptions of labour immigrated women in Handelsnytt 1961-1976).The primary purpose of this thesis is to analyze the written conceptions of labour immigrated women in Handelsnytt, a Swedish Trade Union magazine. The analyses of the conceptions are based on theoretical categories of class, gender and ethnicity.
Klimatanpassning av Ljungby stad mot översvämningar
Climate changing is a growing problem for many countries and communities over
the world. The
cities has a huge work to deal with in their
reforcements of their cities to be resilient ones.
This thesis makes an effort to investigate and
illuminate some of the problem the cities has to solve related to flooding,
hazards, erosions, rising sea levels and crotches. This thesis will help to
find solutions that international and national efforts has produced and handed
out to each other. A lot of communities are charing their excellent tools that
works for them.
Småskalig elproduktion i Arvika
Arvika Fjärrvärme AB, a district heating company from Arvika, today cover 74 % of their total energy production with biofuel wich runs a 16 MW bioler giving process water at saturated liquid state.In recent years Vaporel AB has introduced a new tecnique that gives an external generation of steam after boilers. The concept is built on an adiabatic pressure drop of the saturated liquid in a so called Flashbox which makes a small part of the liquid to evaporate. The generated steam is lead into a turbine where electricity is in a conventional manner.The purpose with this rapport was to do a basic study for the specific system at Arvika where it?s possible to see the potential production of electricity that follows an installation of a flasbox.The final goal was to introduce an economic analysis of a flashox installation at given conditions.To reach our goals we have created a model in Excel where we used the given conditions at Arvika Fjärrvärme to do our calculations. The model has been tested at three different states, of process water returning to potboiler, to be able to decide the optimal operation for the system at present.The studies have resulted in a pressure of the processwater at 14,5 bar (at) and a pressuredrop to 9,5 bar (at) in the flashbox.
Behandlingsvåtmarkers reningseffekt på aktiva läkemedelssubstanser under vinterförhållanden : En studie av fyra svenska våtmarker för avloppsrening
Pharmaceuticals that are found in marine ecosystems are a threatening environmental concern, which is known to harm both animal and plant life. One of the reasons for this problem is that the waste water treatment techniques are not optimized to clear waste water from its pharmaceuticals contain. In this master thesis four Swedish treatment wetlands were studied, and their ability to reduce numerous pharmaceuticals in waste water. The four treatment wetlands that were studied were those in Oxelösund, Trosa, Nynäshamn and Eskilstuna. Two ecotoxicological tests and chemical analysis were used.
Biochar as soil amendment in flow-through planters - for increased treatment of zinc roof runoff
In times of increased flooding, enhanced by climate change, polluted stormwater poses an increased threat to the environment through contaminated water entering waterways. Bioretention utilizes natural processes in soil and vegetation to treat pollutants and combat this threat. Biochar produced through pyrolysis, has a high cation exchange capacity (CEC) and could therefore increase treatment in bioretention systems. This research applies a literature review, interview, and a model to explore the benefits and disadvantages of biochar in order to specify a soil-mix through an understanding of the production process and preferred application rate. High purification through CEC, increased water holding capacity, and carbon sequestration being the benefits discussed.
Uttorkningsmöjligheter i ett fuktskadat badrum med hjälp av spaltmetoden
Buildings today are built to maintain a healthy indoor environment and an efficient energy usage which is probably why damages caused by dampness has increased since the 1960?s.A study between year 2008 and 2010 showed that 26 percent of the 110 000 examined houses had damages and flaws caused by dampness that could prove to be harmful later on. This means that one out of four bathrooms risk the chance to develop damages by dampness. Approximately 2 percent of the houses had already developed water damages. It is here where the problems appear.
Hydroakustisk kommunikation med bandspridningsteknik
This thesis investigates techniques for stealth hydroacoustic communication using spread spectrum. The Swedish naval defense organisations have a vision that all their units should be able to communicate with each other, even between underwater vehicles. But the properties of water makes it a complex channel to use for wireless communications. Radiomagnetic waves have very limited range in water, therefore acoustic waves are used. In this report the basics of wireless communication systems are described including source coding, channel coding, modulation techniques as well as different techniques for spread spectrum.

Inventering av flodpärlmussla i Fylleån norr om Gyltigesjön
Freshwater environments are threatened worldwide, of which many of the species associatedwith freshwater. In 2014, 243 freshwater mussels were on the international Red List. One ofthem is the freshwater pearl mussel, Margaritifera margaritifera, which because of itscomplex life cycle can be counted as an indicator of whether a stream is worth protecting. It's since the early 1900's in decline throughout their range. Sweden is counted as a core area which is why we have not only a national but an international responsibility to conserve the species.
Vilka kvalitetsfaktorer anses viktigast vid inköp av grönsaker och frukt för återförsäljare i Sverige :
Since Sweden joined the European Union all Swedish fruit and vegetables are classified according to EU Quality standards. One important function is the product description and how it can facilitate the trade; for example in better comparing prices and also to guarantee the quality of the product. This quality standards or product descriptions are written as words of an Act and obligatory for all countries that has joined the EU.
It?s often a demand from the customers to be certificated according to some of many certificating systems. One example is the common worldwide GLOBAL GAP-certification system created by the organisation EUREP which represents the leading European retail traders.
Varumärkesrätten inom EU : - ensamrätten i konflikt med EG: s konkurrensregler och reglerna om fri rörlighet för varor
The single market is one of the underlying ideas of the European Union. Free movement of goods and efficient competition are central for the function of the union and are therefore carefully protected by the Treaty of Rome. Exclusive rights of trademarks in the EU can be seen as a method of dividing the common market, preventing the free movement of goods and to be anti-competitive. What comes out of this is that there is a conflict between exclusive rights of trademarks and the rules of both free movement of goods and competition. The aim of this work is to see in which kind of situations the exclusive rights of trademarks can be a part of this conflict but also to study how this problem is resolved by the European Court.
Droppen som fick bägaren att rinna över? - Svenska spelmonopolets förhållande till EG-rätten
Every year the Swedish gambling monopoly serves as a significant source of income for the government. This income is later distributed by the government on various areas for the common good. The question is wheather the state is allowed to preserve this lucrativemarket for itself by any means necessary. Also is it enough to claim that the monopoly exists to protect the citizens, and thus escaping the conditions of EC-law, and its struggle to harmonize trade between the member states? This thesis describes the Swedish gambling monopoly and its relationship with EC-law.
Referensvåtmarker för uppföljning av växtnäringsretention i anlagda våtmarker
One of the environmental problems today in seas, lakes and streams is eutrophication. This is often caused by nutrients such as phosphorus (P) and nitrogen (N) that leak from agricultural areas. A measure to partly prevent the nutrient discharge is to construct or restore wetlands.In order to control the efficiency of nutrient reduction of existing wetlands in the county, the administrative board in Västra Götaland wants to find different criterias for reference wetlands. These reference wetlands should represent other wetlands and be used in future evaluations of reduction of nutrients and design of constructed wetlands. According to the administrative board in Västra Götaland the reference wetlands should have a catchment area of about 50 hectare consisting of at least 70 % arable land, to represent wetlands created to remove nutrients.
Fri rörlighet av varor : Art 34 FEUF och åtgärder med motsvarande verkan - "från Dassonville till Trailers målet"
The characteristics of free movement is the elimination of obstacles to trade between Member States and thus by such, create free movement within the entire union. Therefore art 34 in the Treaty of Lisabon (FEUF) states that all quantative restrictions on imports and measures of equivalent effect are prohibited. The legal approach to measures having equivalent effect is still unclear and the purpose of this paper is therefore to propose a solution to that particular problem. What can be said when it comes to this rule is that the EU-Court has gone from applying a discrimination test to a market access doctrine.According to the Court´s case law, measures having equivalent effects to quantative restrictions are ?All trading rules enacted by Member States which are capable of hindering, directly or indirectly, actually or potentially, intra-community trade?. The question of how to apply the test when it comes to a potential hinder to intra-community trade is still unclear.
