Billions of children, women and men lack access to safe water supplies, whichputs the affected in both social as well as economic despair. This paper willpresent some of the conclusions leading Non Governmental Organisations suchas the UN has presented recently concerning the terms of sustainability. Much ofit is true and important, but nothing can be done without extended cooperationbetween nations worldwide to find arguments that prevent short-term thinkingand economic wealth on the behalf of future sustainability.With a growing population and an increased competition for fresh water, theworld will soon face a severe shortage of good quality water for irrigation. This isbecause the distributions rarely match the demand, neither in Australia nor inAfrica. Important to notice is the major factor that the degradation of theenvironment is not one country?s problem to solve.

The overall aim is to examine how the European Union Water Framework Directive has affected the local water management in the catchment Märstaån situated in the eastern part of the lake Mälaren river basin, Sweden. The first part of the study gives an historical overview of the area with focus on how the old agricultural landscape was handling the nutrient load from farming activities by means of different kinds of wetlands. By using the concept of the procedural landscape, introduced by Torsten Hägerstrand , together with historical maps with dates starting from the 17th century, the pre-modern landscape is analyzed.  The second part is an investigation, based on qualitative data, on how the different actors in the catchment area work together to secure the water quality for the Märstaån river. The analysis shows that the Märstaån catchment river systems are mostly unchanged in the rural areas.  The exception is the mainstream section of the Märstaån river running partly underground today and the Halmsjöbäcken river that is heavily affected by the Arlanda airport situated within the catchment area.

The task was to design and manufacture a submersible displacement pump working with the wobble plate principle. The main task for the Wobble plate pump is to be used as a sewage pump for smaller households or dewatering pump in environments where small flows and high pressures are acquired. For these purposes ITT Flygt sell a screw pump, PC-Grinder 3068. The hydraulic part of the PC-Grinder is manufactured by a subcontractor. Therefore ITT Flygt wants to evaluate an alternative to their screwpump PC-Grinder, which can be entirely manufactured by them self.

The aim of this study is to examine the roles of the children?s librarian in a reading aloud context. To reach understanding in this subject, we have conducted interviews with four Swedish librarians working in public libraries whom are involved with reading aloud practices. Previous research shows that the reasons for reading aloud in libraries are diverse and plentiful. Such reasons can be to spread cultural experiences, help children develop their language skills and promote the library to the public.

Water related problems are highlighted as a challenge to sustainable development and the topic of forests and water is gaining increased attention worldwide. Governing forest and water is a complex issue, as the interactions are affected by policies and actors from multiple levels and sectors. In Sweden, forests cover much of the land and forestry is an important land-use, inevitably impacting the water in the landscape. This study aims to understand and explain the existing governance framework around forestry and water in Sweden. Based on the Policy Arrangement Approach, the study?s research questions focused on the actors involved, the formal and informal rules, the resources and power structures and the discourses related to forestry and water in Sweden.

På uppdrag av Volvo Lastvagnar har detta examensarbete genomförts under våren 2013 för att undersöka potentialer av energibesparande åtgärder i måleriet. Syftet med uppdraget var att utveckla en energimodell över måleriet i byggnad UD, där användaren kan testa olika driftparametrar för att se måleriets potentiella besparingar ur en ekonomisk och energimässig synvinkel. Energimodellen byggdes i Microsoft Excel och arbetet innefattar tydliga redogörelser över de energikrävande processerna, samt över de data som ligger till grund för modellens beräkningar. Data över 2012 års driftsituation har använts som grunddata i modellen och analyser av dessa tyder på att stora energibesparande åtgärder är möjliga.De lastbilshytter som lackeras i Line 3 är de i särklass dyraste, då Line 3 i dagsläget används väldigt ineffektivt. Av den maximala kapaciteten på 12,9 hytter per timme, använder Line 3 endast mellan 8 % och 15 %. Modelleringar visar att en reduktion av drifttiden på Line 3 från ca 95 timmar per vecka till 40 timmar per vecka skulle medföra en minskad driftkostnad på en dryg miljon kronor per år.

This essay aims to explore continuity in water centric cult within the period of the Christianization of Scandinavia (ca 800-1100 AD) and to understand the changing of symbolism of water in pre-Christian cult and early Christian religion. It has previously been thought that Christian priests took over the old holy wells and renamed them after saint, all to ease the pagan people into a Christian lifestyle. But archaeological evidence shows that the cult at these wells, and other water centric sites, where almost completely abandoned a few hundred years before the Christians came to Scandinavia. The Christians should not have felt the need to transform this tradition since it was only practiced in a very small and supposedly private scale. On the contrary, religious activities at these wells seems to increase with the new religion and perhaps this is explained by Christianity itself.

Water hardness indicates the concentration of calcium and magnesium ions in water. Water with high concentrations of these ions is described as hard water and water with low concentrations is described as soft water. Water that is too hard or too soft can lead to technical and economical problems. In collaboration with Midvatten AB, groundwater hardness in the Badelunda esker between Leksand and Avesta has been mapped, and an attempt has been made to explain the variations. For this purpose, different GIS programs, such as ArcView, ArcInfo, IDIRISI, and one geochemical modelling program, PHREEQC, has been used.

In this study potential health risks for employees in connection with handling of bottom ash and bottom ash water at a Municipal Waste Incineration (MWI) plant have been investigated. Air surrounding the bottom ash and the bottom ash water has been examined. MWI is one of the primary ways to manage solid household waste, and bottom ash is the main solid residue produced by the incineration process. Bottom ash constitutes about 15-20% of the original waste. The bottom ash is extinguished in a water bath (bottom ash water).The study was carried out in a MWI plant in Karlstad, Sweden.

To the sewer systems households, industries and other activities are connected. The wastewater is collected at treatment plants where a nutritious sludge is produced. The sludge does not only contain nutrients, but also hazardous substances originating from different activities in society. To reduce the flow of hazardous substances to treatment plants and to create a sustainable recycling of plant nutrients the Swedish Water & Wastewater Association has developed the certificate system REVAQ. This certificate requires a good quality of the sludge but also that the treatment plants maps the origin of the unwanted substances.

AbstractThe purpose of this study is to find out how pupils give expression of a water cycle model and if the model causes any misunderstanding. Two problems constitute the starting point for this investigation. The first question is: how do the pupils explain the water cycle with the help of the jar model (can of glass). The other question is: can the children see any similarities between the can of glass and our earth. Qualitative semi structured interviews with seven pupils in the ages of 8-9 have been used to show the pupils? own thoughts and how they express them.

Ever since its conceptual birth, the questioning of consequences due to the implementation of ideas from the reformation doctrine, called New Public Management, has been a common occurance among those who have dedicated themselves to research in superior methods of Public Administration. What this thesis aims to do is shed light upon what value-conflicts may occur within public administration organisations when they begin to idealize the rationalization of economic issues. The goal of this thesis will be fulfilled through the creation of two ideal types of public administration that exist in opposition to each other. These two ideal types will show two different views on how decision-making and organisation will be managed in their respective sectors. By doing this, there will be clarification as to what conflicting values arise with the implementation of ideas taken from New Public Management, as well as defining the fundamental difference between which ethical decision model is used..

In Sweden there are 1894 small-scale hydropower plants in operation, which together generate 4.3 TWh of electricity per year according to Swedish hydropower compound (SVKF, 2011). This corresponds to the annual consumption of about 860,000 Swedish households (based on an annual consumption of 5000 kWh). In the mid-1950s there were around 4000 small-scale hydropower plants in operation in Sweden before cheap fossil fuels and uranium competed with them, in the current situation only 1,894 of these are in use. If slumbering small hydropower plants once again would be taken into use and some new ones are built, we would be able to extract about 7 TWh of renewable electricity from these annually in Sweden, representing about 1.4 million households.The thesis intends to calculate and construct a hydroelectric power plant at the existing dam in Olofsfors and give suggestions on how the power station should run during the time that fish migration is greatest in Leduån.The turbine and generator to the station in Leduån at Olofsfors is designed by the height of the fall and the water flow through the dam. The turbine selected for the station is a CK-1000RM turbine with a 4-pole 250 kW generator from Cargo & power turbine Sweden AB, which is expected to deliver 1.2 GWh per year.

Syftet med examensarbetet är att utreda orsaker till turbiditet i dricksvatten, från Gäddviks vattentäkt till konsumenter i Luleå kommun. Målet är att ge svar på vilken typ av partiklar som orsakar turbiditen. Analyser utfördes före och efter filtrering av dricksvatten.

Mosquitoes are found in extremely large numbers in the lower parts of the River Dalälven. In the year 2000 the mosquito nuisance was especially high, resulting in foundation of the Biological mosquito control project. Since 2001 mosquito larvae are controlled by using a biological pesticide BTI (Bacillus thuringiensis ssp israelensis). The mosquito fauna in the area is dominated by flood water mosquitoes, a group of mosquitoes that are very aggressive and form new generations of mosquitoes during every single flooding event during the summer. To be able to efficiently control the mosquitoes it is essential to know the extension and locality of the flooding.
