The plants in the genus Elatine are characteristic for oligo and mesotrophic lakes. This study focuses on Elatine hexandra one of the four species in Sweden. It is stated as vulnerable by the National Environment Agency and a conservation plan with guidelines to preserve the plant in Sweden is under preparation. There have been a few previous studies investigating this plant in other countries but this is the first one for Sweden. The aim of this study was to investigate the distribution, growth and reproduction of E.

The population growth and urbanisation in low-income countries bring issues of Poor living standards and miserable sanitation conditions onto the agenda. If well-functioning waste management systems were developed, this could master some of the problems. The already existing local informal waste handling system that is common in many low-income countries, needs to be developed with proper sorting and composting solutions to decrease the environmental burden and improve the overall situation in the dense cities. This master?s thesis project is performed with the intention of developing functional decentralised waste management units in the city of Pune, India.

Business is changing and so are society?s expectations. Companies are expected to take responsibility for their trade and the context they are operating in, by looking at socially, economically and environmentally aspects. Many companies handle it by implementing corporate social responsibility (CSR) to their line of action. This is often handled by collaborating with other organisations, such as non-governmental organisations.

The numbers of natural disasters caused by extreme weather are increasing through out the world. A large majority of the research concerning the climate shows that this is a trend that can be expected to continue. At the same time the urbanisation is increasing more than ever and for the first time in history more than fifty percent of the population lives in a city. How we build these cities will have a crucial importance for our adaption to the new climate. In Sweden, our capacity for an adaption are high because of our economic situation as well as our rather well built society.

It is important to construct or recreate different types of wetlands and study their retention of nutrients, since knowledge of their effectiveness in this matter is Poor. In 2003 a wetland was constructed on an old meadow on the western shore of Lake Bornsjön in central Sweden. The main purpose of the wetland was to reduce the amount of phosphorus entering the lake, which is the back-up water supply for Stockholm when the city cannot obtain water from Lake Mälaren. Large areas around Lake Bornsjön consist of agricultural land and the nutrient concentrations in the inflows to the lake are usually relatively high (approx. 1 mg/l total nitrogen and 0.05-0.1 mg/l total phosphorus).

This essay constitutes an attempt to expose, with reference to contemporary animal research, the limits of Martin Heidegger?s concept of the being of animality in Die Grundbegriffe der Metaphysik (1929/30) and to propose some possible ways to think, within the philosophical style of this particular work, the being of those animals that most distinctly transcends Heidegger?s concept. The essay seeks to address the following question: Do the results of contemporary animal research expose ways of being within animality that withdrawal from Heidegger?s concept of the being of animality in general, and if so, how should we think these new ways of animal being? The motivation to ask this question, I argue, are immanent to Heidegger?s thinking in at least three ways: 1) Because of his standpoint that philosophy cannot, in any meaningful way, create an ontological concept of animality without an orientation towards the results of the positive sciences; 2) Because of the unfinished and tentative character of Heidegger?s analysis, a character that is such that it should be seen, according to Heidegger himself, as an essential point of departure for further thinking; 3) Because of Heidegger?s view that the being of the animal are such that it involves the withdrawal of this very being from any originary access, a withdrawal that necessitates an infinite return to the question concerning the being of the animal. The essay wants to be a continuation of lines that are present in Heidegger?s open-ended thought on this theme rather than to be an external critique that approach the text, which is most often the case, as a closed point of view which we are forced to affirm or reject.

This thesis work has been performed at the Division of Assembly Technology at Linköping University for a period of ten weeks. The work is part of the project ProFlexA, which is a research project in collaboration between Linköping University, Lund University, and industrial partners such as Combi Wear Parts and Smålands Stålgjuteri AB.The casting process creates random incurred burrs and defects, which must be removed during a cleaning process to make sure that the cast can be sold. Automation has long been sought for the cleaning of castings due to, among other things, Poor working conditions for staff, but this has proved difficult to implement with today's technology. Automation has for some time been available for more capital strong companies with large annual volumes, but for smaller companies with small-and medium-sized volumes, automation has not been an option.The goal of ProFlexA is to develop an automated cleaning cell aimed at small-and medium-sized volumes.The goal of the thesis is to do a pre study at ProFlexA?s partners on cleaning of castings, and develop concepts for automated cleaning of castings.By recording the process and cycle times, the cleaning of castings has been documented as it works today, and on this basis, information and statistics has been compiled.

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.

The relatively Poor economy in European dairy farming might be improved from efficient feeding systems and dietary management. Increasing herd sizes and transition to loose housing systems in Sweden, increases the possibilities for other feeding systems than separate feeding that is the traditional feeding system in Sweden. Other possible feeding systems are partial mixed ration (PMR) and total mixed ration (TMR), where the TMR system sometimes is associated with overfeeding and thereby increased environmental impact and high feed cost. Diets providing nutrients above or below animal requirements are considered as unbalanced, which in turn are associated with reductions in health, fertility and milk production. On the other hand, a balanced feed ration improves feed efficiency, nitrogen utilization and profitability.

Läkemedelshanteringen är ett av sjuksköterskans ansvarsområden inom hälso- och sjukvården. Utifrån kunskap och lagar skall den bedrivas på ett patientsäkert sätt men trots det sker läkemedelshanteringsfel vilket innebär risker i patientsäkerheten.Syftet med studien var att beskriva faktorer som påverkar säkerheten i samband med sjuksköterskans läkemedelshantering. Studien genomfördes som en litteraturstudie. Resultatet visade att vanliga läkemedelshanteringsfel är utebliven dos, fel administreringstid, fel dos, fel administreringssätt, fel läkemedel och läkemedel till fel patient. Faktorer som påverkar sjuksköterskans läkemedelshantering är felaktiga och dåligt skrivna läkemedelsordinationer, distraktion under läkemedelshanteringen, bristande rutiner samt införande av ny teknologi.

The management of water resources and waste water varies between the countries of the EU. For many years, a large part of the water in Europe has been contaminated by, among other things, insufficiently treated waste water and emissions from agriculture. The EU Water Framework Directive 2000/60/EC and the Urban Waste Water Directive 91/271/EEC are intended to harmonize fresh-water management and waste water management within the whole EU, aiming at safeguarding drinking water of good quality and a high quality of all water within the EU today and in the future. There are however some problems concerning the waste-water directive. One problem is the huge investment needed in Slovakia to fulfil the demands of the waste-water directive for waste-water management in larger communities (with more than 2000 inhabitants).

An Internet application, VEDAIR, for estimation of air quality in regions with small-scale combustion of bio fuel has been developed by Swedish Meteorological and Hydrological Institute with financing from Swedish Energy Agency and Swedish Environmental Protection Agency. The model contains user interface and a coupled model concept where concentrations of atmospheric pollutions are calculated for regional, urban and local contributions. In this report the model is described and a first study of air quality considering PM10 (particles with a diameter less than 10 µm) in two Swedish municipalities, Vänersborg and Gnosjö, is introduced.According to the result, there are areas with Poor air quality even in smaller Swedish municipalities, mostly due to high emission from buildings with older wood heating furnace without hydraulic accumulator.In Vänersborg three areas were analysed in VEDAIR for the year 2003: Vargön, Mariedal and the downtown district. In the whole municipality the upper evaluation threshold for PM10, which is defined as 14 µg/m3 for annual average, was exceeded due to background contribution of particles. In all areas, however, the concentrations of PM10 were less than the environmental quality norms.

Running water-pathways have played an important roll in Sweden and frequently been manipulated. One profound change was made during the period of logging when streams were cleared from obstacles as big boulders, sharp bends and side-streams. Dams and different constructions gave control of the stream water and the streams became channel-like with a homogen structure. This interference gave problems for many fish populations and resulted in a shortage of feeding habitat, over-wintering habitat, spawning habitat, unnatural flow regimes, sedimentation, unnatural temperature fluctuations. Many of these historical changes of the watersheds are now subjects for restoration, ie., bring back the streams to what we believed it was before the change. However, what once existed in terms of complexity is now gone and difficult toreplace.

The dry period is usually 6-8 weeks and in this period the basis of the performance in the following lactation is settled. In an average herd about 15% of the cows are dry (Marcussen & Krog Laursen, 2008). In many herd the dry cows are set aside, that means setting aside 15% of your herd, at the time when they are preparing for their next lactation. The recommendation for number of groups differs depending on country traditions or reasons for grouping. If you look at recommendation for feeding, some companies selling feeding equipment advocates one group throughout the dry period, but the number differs from one to three.

The master's thesis investigates how the concept traditional knowledge is represented by international organizations that are influential in development work and policy making. Departing from a theoretical framework drawing on Michel Foucault, constructed aspects of knowledge and the power relations knowledge production implies are highlighted.A recent interest within library and information science and practice to document this kind of knowledge raises questions about how traditional knowledge differs from other forms of knowledge and how knowledge organizational tools can be applied. Investigations, which critically explore the concept traditional knowledge, the power relations the concept creates as well as the interests and purposes it serves, have been surprisingly absent within the discipline. The focus in this master's thesis is how traditional knowledge is conceptualized by international organizations. A discourse analytical approach reveals the power relations that are inherent in their descriptions of traditional knowledge and how they describe the relevance of the concept for their work.
