The purpose of this bachelor´s report is to expand the knowledge about heat supply of a small house in Malmö. The heat supply will be provided from solar panels in combination to two accumulator tanks which will storage the up heated water and a pellet boiler.The technique used here is warmth storage in water over seasons, which will provide the total need of heating for the house. Accumulator tanks in combination to solar panels gets more and more common in Sweden but this far it´s unusual to use it for storage over seasons. This report will highlight many of the difficulties associated whit heat storage and give information about a system's possible design and function.The design of this system is decided early on. An accumulator tank is placed 2 meters down in the earth on the backside of the house.

The Swedish energy system will be influenced by many future changes, such as energy and climate policy objectives. The installation of more renewable electricity could increase by using solar energy. Over the recent years, grid-connected photovoltaic (PV) systems have increased dramatically in Sweden, partly due to various support systems and compensation models. These support systems have been designed to make it easy for individuals and businesses to invest in self-generated electricity and thus contribute to the transformation of the energy system.The introduction of a higher proportion of solar energy may in turn affect the Swedish electricity system. This could mean that the electricity companies will be facing a number of changes in the near future.

This paper used a qualitative technique from a social scientific perspective, a model based on Hewitt and his theory of the self-concept. The purpose of this study was to investigate why some elite athletes experience troublesome periods after their career ending. Interviews were performed with five elite athletes with varying experiences after career ending. The length of the elite athlete careers vary between 7 to 17 years. Two groups were made based upon experiences after career ending.

With growing economies and better living standards in many parts of the world today, there is a need of expanding the capacity of generating electricity. The alternatives for renewable energy technologies are not fully developed and have still some problems to conquer.The company Minesto has developed a technology that is called Deep Green. It is designed to gain electricity from tidal currents. Deep Green works in a similar way as a kite that is attached to the seafloor with a moving wire. It contains of a wing that moves due to the water current.

The purpose of this study was to examine how four different choir conductors work with children's and youths' individual voices during choir rehearsal. Further aims of this essay are to shed light upon relevant research within the topic. I used a qualitative method of researching observations with low structure and structured interviews.

The moisture content in 10 deliveries of tree parts and 10 deliveries of wood residues were measured with different methods to analyze the quality of procedure used at Dåvamyran today. At the same time a survey was made on the measure procedures used at heating plants in Sweden The majority of the heating plants in Sweden use weight and moisture content as base for payment but at some plants only volume. The moisture content is usually estimated by drying wood chips in an oven but few plants a visual estimation is used. At few plants moisture content is estimated spectroscopicily. The techniques using near infra read light and other electromagnetic are still at a test stage. The methods of measurement used today are quit unreliable for the individual deliveries and there is a risk for systematic mistakes.

The purpose of this study is to give an overview about iron fortification from the view of technique and health. Example of a technical aspect is different iron compounds which are used for fortification like ferrous sulfate, ferrous fumarate and elemental iron. In the aspect of health the big question is if iron fortification can improve the health in reducing the prevalence of anemia. The study focuses on flour fortification with iron in Egypt and Iran and involves a literature study with scientific articles. Also information from WHO (World Health Organization), FAO (Food and Agriculture Organization) and FFI (Flour Fortification Initiative) are used.Fortification means an intentionally increasing of the content of micronutrient in foods with the aim to improve the food quality and deliver a nutritional benefit to the consumer.

I forskningen har organisatoriskt lärande uppmärksammats, men inte institutionaliserats. Det organisatoriska lärandet påverkas i stor grad av nyckelpersoner vilket ledare och mellanchefer är. Organisatoriskt lärande styrs av det individuella lärandet vilket därför har en stor betydelse i sammanhanget. Ansvaret för det individuella lärandet läggs oftast på organisationens ledare och för ledares individuella lärande är reflektion och erfarenhet en avgörande faktor. Därför var studiens syfte att bidra till forskningen genom att undersöka hur kritiska situationer påverkat ledares lärande och bidragit till det individuella och organisatoriska lärandet.

Syftet med litteraturstudien var att beskriva sjuksköterskans rutiner i samband med insättande och omvårdnad av perifera venkatetrar samt att beskriva observationer och åtgärder som sjuksköterskan gör för att undvika komplikationer. Artikelsökningen har skett i databaserna: Elin@Dalarna, Blackwell Synergy, EBSCO-host och Elsevier. De sökord som använts i olika kombinationer var: peripheral, intravenous, catheter/line/cannula, handhygiene, nurse, infections, phlebitis, routine och technique. Artiklarna skulle vara vetenskapligt skrivna på engelska och fick inte vara publicerade före år 1996. Sammanlagt inkluderades 20 artiklar i litteraturstudien varav 16 kvantitativa, 2 kvalitativa och 2 där båda designerna fanns representerade.

The number of people in the world and the urbanization increases. This leads to a bigger need of space for the built environment, space that soon doesn?t exist. A large portion of humanity?s energy disposal is used for heating of buildings.

The essay depicts the opposite views of the director and an actor during the filming of a specific scene in a feature film. The actor feels that he is not being listened to. This leads to unforeseen consequences for the director, as the actor no longer wishes to take part in the marketing of the film prior to its opening night. Everything is seen from the director?s point of view, she is working in a film world dominated by men.Questions are being asked if the director?s instructions are clear enough or if the actor, fearing getting lost, is mixing up his own feelings with those of the character he is portraying? What happens to the collaboration and how does it affect the rest of the team and the completion of the production? The director is also the producer.

This Master?s Thesis aims to investigate and assess the methods used to decrease the discharge ofmetals, primarily copper, from the water purification plant at Assa Industries plating factory inEskilstuna.Literature studies of the purification methods precipitation, ion exchange, evaporation, reverseosmosis and electrolysis has been done to appraise the adequacy of the technique. Thesetechniques are commonly used for purification of industrial waste water.Assa has four plating lines: the Trumline, the big Zinkline, the new Zinkline and the Decorativeline. The new Zinkline is the most modern of the four lines and purification is done byrecirculation over an ion exchange unit. The demand for fresh water is thereby heavily reduced.The Trumline, the big Zinkline and the Decorative line all use older techniques.

On a request from the water sewage plant Gryaab in Gothenburg a power quality survey was performed. The voltages and currents have continuously been sampled in the incoming 10 kV substation HSP01 from April-August 2008. Power quality measurements were also performed in Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of the induction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps to the plant. The reason for the latter measurement was due to registered negative transients each time the motor was connected to the grid. The cause of the transients could be explained by the coupling in the substation, the ageing of the motor which could result in damage of the bearings or resonance in the motor circuit which amplifies high frequency harmonics.
