When a combined heat and power plant produces heat and power it often faces a deficit of heat load during the summer or other periods of time. This heat is often unnecessarily cooled away or the power production has to be reduced or shut off. If it is possible to store heat from periods with low heat demand to periods with high heat demand one can get many benefits. Among these benefits are: increased power production, decreased operation with partial load, uniformly distributed load.To be able to store heat in situations like this long-term thermal heat storages are needed. In this thesis five different types of stores are presented: rock cavern storage, tank storage, pit water storage, borehole storage and aquifer storage.

The study aims to contribute knowledge about children's perceptions of the leisure-time as a learning environment. The study can be seen as an attempt to highlight the possible learning in the leisure-time, formally or informally.The study is based on two group interviews with a total of 11 children and was conducted by an interview guide with question areas to be discussed freely so that the children could give as full an answer as possible.Main results of the study show that children feel that they are staying at the leisure-time to get care when their parents are working and that they primarily associate the leisure-time with playing. The results show however that children feel that they learn things when participating in the leisure-time teaches controlled activities.It is possible to draw conclusions about the child actually experienced the leisure-time as a learning environment, but it can be difficult to identify when and how learning actually occurs. However, children do not perceive that there is learning while they play..

The river Selångersån runs through thenorthern Swedish city of Sundsvall, splittingthe city in two as it winds through thevalley between Södra- and Norra Stadsbergetand out into the Baltic Sea.The river is a national interest of nature conservationbut at the same time in the middleof an urban development string for the city,creating a complex situation of developmentcontra conservation of natural environment.This project attempts to create a strategy oflandscape urbanism for the area surroundingSelånger Bay, four kilometers upstreamalong Selångersån. A sensitive wetland, todayrather forgotten but with great potentialfor introducing wild nature as an active partof the city. Or rather, initiating a processwhere the built environment can infiltrateand enrich the natural environment gradually.A city park in this location to initiate thisprocess could be a joint project of the city?sresidents with the scope to become a projectin constant development.The idea of the project is to offer a large ecologicalpark and meeting place near the citycenter. This will be achieved by clarifyingthe activities and values that already existin the park, such as the largest living deltai the region, football fields and a medievalchurch ruin, and by creating new paths.

The access to good sanitary facilities is an important factor that elevates the experienced living standard as it improves hygiene and reduces the transmission of deseases. The ratification of the millennium goals by 189 countries demonstrates that this is an important international issue. Together the countries have taken upon themselves that the proportion of the population that lacked access to sustainable safe drinking water and sanitary facilities in the year 2000 will have been reduced by half by the year 2015. In Peru, the construction of sewage pipe networks to transport the sewage out of the direct human environment is progressing. The safety and sustainability of these systems can be questioned, since in Peru the sewage seldom receive any treatment before being emitted to a recipient. This is taking place in Picota and sorrunding villages as well. In the last 25 years several systems implementing small-scale onsite treatment have been introduced throughout Latin America in an attempt to give more people access to sustainable and safe sanitary facilities, reducing water consumption and taking advantage of the agricultural values of the sewage fractions while protecting the environment from its negative impact. In this study three different sanitary systems and the effects of different population growths were compared.

Non-profit organizations gain increasing attention in society but their legitimacy often decrease by scandals in separate organizations. Doctors without borders (MSF) constitutes an exception and has managed to retain their legitimacy. The aim of this study was to examine how MSF built and retained its legitimacy towards institutional actors in their environment, when the branch in general is suffering from a crisis of confidence. In a case study, this was done by identifying the institutional pressures on MSF and examining which strategies MSF uses to handle the pressures. The study was conducted through qualitative interviews with employees at MSF and actors in their environment.

What is e-leadership and how can it be framed in a distance context? How can work motivation be understood as a correlated theme? In prior leadership research and theory it has been taken for granted that leadership occurs in a face-to-face environment, so how to study leadership in a remote context? According to recent research, e-leadership defines this leader-member relation in this new arena, and a central focus of this research has been on communication. Communication is a central theme in the remote setting because it is the only interaction arena which allows leadership to be seen and understood. By conducting a case study in a multi media organization with distance working journalists as focus group this essay aims to bring a deeper understanding of how e-leadership works and how it effects work motivation. The field of media organizations is interesting to study as distance work is not an unusual working environment for journalists, and research has indicated that work motivation needs for these highly specified creative workers are somewhat differentiated from other, for example industrial workers, which implies that motivation theories urges an update.

Det serbiska luftvärnet sköt ner ytterst få av NATO:s flygplan under Kosovokonflikten. Trots det så visar det sig att NATO:s luftoperationer indirekt påverkades i stor skala av luftvärnet. Även om man sköt ner ytterst få av de anfallande flygplanen uppnådde serberna indirekta effekter på NATO som försvårade hela operationen. Syftet med denna uppsats är att problematisera och definiera begreppet indirekt effekt inom ramen för luftvärn samt att applicera detta begrepp på en vald konflikt.Uppsatsen består i huvudsak av två sammanhängande undersökningar. Först sker en begreppsutredande studie som resulterar i en definition av begreppet indirekt effekt.

Introduction:A good work environment and good resources among district nurses? and general nurses? are important in the provision of good nursing care. For patient security it is also very important that resources and time are used in an appropriate way. A lot of time is spent on non-core activity, for example administration takes more and more time, which can result in feelings of stress.Aim:The aim was to describe how district nurses? and nurses? in primary care perceived their work environment, how their worktime content was distributed and if there was some connection between perceived work environment and the distribution of work time.Methods:A mapping of the content of the work was made in two parts.

Föreliggande arbete tar sin utgångspunkt i en observation av hur United States Marine Corps (USMC) använde pansarvärnsrobotförband förvånansvärt aggressivt under Gulfkriget 1991. Med syftet att studera denna taktik och att därigenom skapa en ökad förståelse för pansarvärnsrobotförbandens taktiska möjligheter/begränsningar skapas en problemformulering som undersöker vilken relevans USMC:s taktik med pansarvärnsrobotförband i Operation DESERT STORM har för svenska armén idag? För att kunna besvara denna övergripande fråga bryts den ned till tre forskningsfrågor som beskriver vilken taktik som karaktäriserade USMC:s pansarvärnsrobotförband, därefter förklarar motiven för denna taktik och slutligen värderar vilka lärdomar som svenska armén kan dra från detta 2012.Resultatet visar att marinkårens taktik i huvudsak har låg relevans på grund av de unika förutsättningar avseende terräng, siktförhållanden och teknikasymmetri som förelåg i Persiska viken 1991. Terrängen var nästan helt platt vilket gav god effekt för pansarvärnsrobotarnas övertag i skjutavstånd gentemot irakiska stridsvagnar. Oljerök och dimma gjorde att deras termiska sikten kunde verka där inga irakiska motsvarigheter fanns.

The 17th October 2014 the Swedish Armed Forces (SwAF) introduced an intelligence operation in Stockholm archipelago after receiving credible observations regarding illegal underwater activities. Following the data collection and associated analysis it could be stated with certainty that a foreign submarine had violated the Swedish territorial waters. Media depend on SwAF to provide them with accurate information due to the confidentiality in these matters and the general area of investigation is therefore how the actions of the Swedish Armed Forces, in the submarine incident 2014, were portrayed in the Swedish media. Newspapers and blogs of defense policy represent the media and the thesis is based on the theories constructed by Graham Allison, the rational actor, organizational behavior and governmental politics. Furthermore, it is relevant to examine if there are any similarities or differences in how the submarine incident is illustrated, and what may be the reason for any possible occurrences.

For the company to work well, it is necessary with a good economy, a high qualitative production and a well working system concerning the environment: the whole cycle on the farm needs to be working. At the same time, debaters about the environmental impacts are also requiring higher demands for the dairy farmers and therefore also the management programs. Management programs for feed evaluation calculations have been more developed over the years. Big amounts have been invested in the new feeding system with NorFor, but no one seems to have asked the dairy farmers what they themselves want to spend their money on, and what they need help with. For the dairy farmers it is necessary that the whole company is controlled in the right way, and much more than just feed evaluation is included in this.

Bakgrund: Hjärtats slag har länge förknippats med skillnaden mellan liv och död. År 2010 genomfördes 6 358 hjärtkirurgiska ingrepp i Sverige. De vanligaste ingreppen är koronar bypass-operation, klaffoperation och operation på missbildningar på hjärtat. De viktigaste delarna i pre- och postoperativ omvårdnad är helhetsbedömning av patienten, ge information, ge råd om nödvändiga livsstilsförändringar och att finnas som stöd för patienten. Syfte: Att beskriva patienters erfarenheter före och efter hjärtkirurgi.

Rapportens studie jämför en distribuerad och mobil databasmiljö med avseende på frågehantering. Områden som fokuseras inom frågehantering är: dataorganisation och distribution, lokaliseringshantering, skalbarhet, frågekostnader samt frånkopplad operation. Rapportens slutsatser fastslår att grundläggande skillnader inte existerar mellan miljöerna med avseende på frågehantering, vilket ger till följd att formulerad problemhypotes verifieras..

This thesis is about how the library can help immigrants integrate into theswedish society. By studying leading documents of the libraries in Malmö,Stockholm and Umeå in search for how the relate to work consideringimmigrants and integration I have studied the library as a bridge betweenbeing included and excluded in the society. The thought is that the libraryopens the door to new worlds both for immigrants and born swedes toobtain knowledge about a culture different from their own.In my thesis I reached the conclusion that library on a day to day basisworks with the integrationprocess for immigrants. Although the leadingdocuments should evolve since they show gaps and seem somewhatmisguiding in their presentation of the libraries function. The librariesshould work more with analysis of the environment that they are active in sothat they are more individualized for the people around it.
