The purpose of this study is to investigate in what extension students experience that computer and videogames affect them. I have chosen to focus on the physical, mental and social affect that this activity might bring them. I have also examined how much time the students spends in front of the computer or the videogame and in which social context they play.The method I have chosen to use is a quantitative opinion poll which I used in three classes of the later junior high and I have also conducted five qualitative interviews.The conclusions I have drawn from this investigation are that computer and videogames affects teenagers both physically and mentally. Physically the affects of playing videogames mostly can be derived to the physical inactivity they expose themselves to. The students themselves did not experienced any positive physical affects from their playing.Amongst the mental affects that stood out the most I recognized the social training that online gaming provided and also the intellectual stimulation that certain games offered the player.

The goal of this paper is to find out how solar cells can improve energy efficiency on-board M/S Sydfart. The paper is based on a number of energy measurements on board the M/S Sydfart. The solar surface is calculated by measuring the available space for installing solar panels. Global radiation data is taken from STRÅNG's database, the data is then used to calculate the theoretical power produced by the solar cells. Energy efficiency is analysed in two ways.

During the last year?s Swedish agriculture have had difficult times, with decreasing prices and at the same time increasing production costs, which has led to bad profitability and faith in the future. The dairies in Sweden have also had a rough time and there have been large rationalizations during the years. In the beginning of the 20th century there were almost 1700 diaries in the Swedish countryside. There has been a large technical development during the 20th century resulting in a decrease in diaries to only 46 in the whole country today. They are owned by 15 diary companies, of which 7 large and dominate on the market and the rest are small-scale companies. With this development the confidence and feeling for the diary companies also has decreased.

In ambition to produce more and better harvests, artificial fertilizers are used to produce a better growth of crops in the agriculture landscape. This contributes to leakage of nutrients. Our forests also exhibit a leakage of nutrients. Air pollution contributes to more nutrients. High precipitation with high water flows as a consequence seems currently to occur more frequently in the county of Halland.

Title: Communicate ? to provide an opportunity Authors: Ida Eriksson & Petra LindbergTutor: Johan Grinbergs, Mälardalen UniversityExaminer: Cecilia LindhSubject: Bachelor's essay, Business AdministrationKeywords: communication, internal communication, channels, communication models, communication theory, information, organizationPurposeThe idea of this study was to describe how ABB Sweden?s internal communication and information appeared in Västerås. The aim is also to see what tools and channels they use to communicate information internally and see how employees perceive them in Västerås.MethodWe have read literature in form of books and articles that discuss theories on the subject communication including internal communication, channels and tools. Interviews were conducted with employees of ABB and were to serve as the basis for our empirical work. A survey by the Communication Center was made in the spring 2010 and was also the basis for our empirical work.ConclusionsThe communication has been increasingly from one-to two-way communication. To get a functioning organization, it is required that the internal communication in the first place will work.

The aim of this thesis was to answer a number of questions about the environmental consequences of aircraft de-icing. A further aim was to suggest how the environmental consequences due to the release of de-icing fluids can be measured and reduced.The main impact of the aircraft de-icing on the environment is due to the large oxygen demand for the degradation of glycol based de-icing fluids which are released in the environment. The effect of the increase in oxygen demand depends on where the degradation occurs in the ecosystem. In a sensitive ecosystem, the large demand of oxygen could provide an anaerobic environment which would be harmful for many types of organisms.In order to reduce the negative effects of the applied de-icing fluid, there is some type of collection system at every regular airport in Sweden. The methods of collection can be divided into two general groups, hydrological isolation or vacuum sweeper trucks.

The foundations of the Swedish labour market have shifted due to a number of new circumstances affecting its framework. Employment is no longer a right taken for granted but rather something one should work hard to achieve. Given the new conditions, employers are not only trying to ensure their own businesses survival but also uphold the structures of our society. Competition between enterprises forces management to forge new boundaries to maintain profitability.Concerns have arisen whether or not these so called management strategies are within the limitations of the law. As a result and as a response to the design of the labour laws creativity is peaking to overrun the statutory regulations.

With an increased demand for biomass based energy and with development of better technique harvest biomass, new possibilities open up. With the possibility to combine traditional cleaning of road?s right of way with biomass harvesting, the work of suppressing tree vegetation could become profitable or at least decrease the road maintenance cost. However, knowledge about productivity and profitability in mechanical biomass harvesting in roads? right of ways are still limited.

The calculations in this thesis are evaluating the profit as a consequence from treating young stands of pine in Sweden with birch bark extract, BBE. Treatment is to be done with the object to lower or fully reduce the moose browsing on pine. The study is made in three versions. The results from each version separately will follow below. Version I.: The size of the moose population is in no way affected by the reduced resources of food as a consequence of large scale treatment with BBE on pine. Results show profit at a 3 percent level of interest with the exception of treatment program with more than 4 treatments all together and with the exception of Västerbottens Län with an early first treatment. Version II.: The population of moose decrease from 10 to 5 individuals per 1000 ha as a consequence from large scale treatment with BBE on young pine stands.

The Apollo butterfly, Parnassius apollo, is categorized as Near Threatened (NT) in IUCN Red List. Today in Sweden it is found only in strongly fragmentized populations. In the county of Stockholm, P. apollo exists exclusively in some islands of the archipelago and with one mainland population in Stora Vika. This study has the purpose of expanding the knowledge of the local conditions for the butterfly in the south parts of the county of Stockholm and thereby contributes to a sustainable land management that can preserve the Apollo butterfly.A comparative study was done between areas where the butterfly today have: a stable population (Stora Vika, Utö and Ålö), has disappeared (Muskö and Yxlö) or is strongly declining (north part of Ornö).

Gerbera jamesonii is a plant with a large amount of pollen and various flower colours and a favourite host plant for Frankliniella occidentalis. The best growing temperature for gerbera is approximately 20°C. Frankliniella occidentalis or the Western Flower Thrips is a small insect that has become an important pest in greenhouse cultivation all over the world. The high temperatures in the greenhouse are favourable for F. occidentalis.

Nutrient enrichment is the main cause of the increasing eutrophication process in the Baltic Sea during last century. A prerequisite counteract this process the load of nutrients to the Sea must be investigated. The large contribution of nutrients to the Sea is caused by emission from the rivers within the drainage basin. For the total emission of nutrient into the Sea the retention process in the rivers has big influence. This process in the river system has been assumed as a not important part of the nutrient cycle.

The forests of Sweden are constantly changing. Map studies indicate that the amount of deciduous trees in Sweden has decreased in recent years in favor of the coniferous trees. The National Forest Inventory has since the early 1920s monitored the Swedish forests and in recent years has made the old data digitally available. In the present project, we have investigated how the numbers of stems in different diameter classes have changed for birch and other deciduous trees. The inventory was conducted in the same manner as in the first forest inventory.

Integration is a concept that is very topical in today's multicultural-cultural society. Integration means that everyone should have the same rights, opportunities and obligations to society, regardless of extraction. What counteract integration is segregation, which implies a distinction between different groups and where there exist an inequality between them. Segregation is widespread in Sweden today and the exclusion that it creates needs to be broken. The aim of this paper is to examine if it is possible to promote integra-tion through physical planning.

Bakgrund och problem: Genom att erbjuda val vid redovisning av aktuariella vinster ochförluster minskar möjligheten till jämförelse mellan bolag och länder. IASB har valt attgenomföra ett borttagande av korridormetoden, vilket är den redovisningsmetod som i dagslägettillämpas av majoriteten av företagen på Stockholmsbörsen Large Cap-lista. Detta har belystssom ett problem i flertalet studier och kommer leda till en väsentlig påverkan för många av deföretag som tvingas till ett byte 2013.Syfte: Uppsatsens syfte är att undersöka varför vissa företag på Stockholmsbörsen inte tillämparkorridormetoden och vilken metod de valt istället samt vad den reviderade standarden IAS 19kan komma att få för effekt för företag som tvingas till ett byte från korridormetoden 2013.Avgränsningar: Uppsatsen studerar enbart företag noterade på Stockholmsbörsen Large Caplista.Vidare kommer enbart de företag som tillämpar förmånsbestämd redovisning avpensionsåtagandet att studeras. En avgränsning till industrisektorn enligt OMX Nasdaq ICBindelning har sedan gjorts för att djupare studera företagens motiv till att redovisa i övrigttotalresultat samt de förväntade effekter av borttagandet av korridormetoden.Metod: Uppsatsen baseras på en flerfaldig strategi där både en kvantitativ och kvalitativ metodtillämpats. Vid insamlandet av de totalt 58 årsredovisningarna från företag noterade påStockholmsbörsen Large Cap-lista som ligger till grund för studien tillämpades en kvantitativansats.
