The aim of this thesis was to examine if it is possible to keep nitrogen in the form of nitrate(NO3-) in ponds from one season to another by keeping a high concentration of oxygen in thepond water. This hypothesis was tested by doing a lab experiment where two systems werecompared according to nitrate concentration. One system had high concentration of oxygen inthe water and one had low concentration of oxygen. Before the main experiment wasconducted I did a pilot study to test the system setup and included parameters. The result fromthis study and the main study did not show the same result.

This thesis is performed in cooperation with Prodelox AB and JTI (Swedish Institute of Agricultural and Environmental Engineering). The purpose of the project is to generate and develop a WC-technique with a closet sewer that keeps a higher TS-substance than 1.5 %. The WC-technique is mainly directed towards permanent households in sparsely-populated areas and cabins. The goal is to generate concepts of toilets with an extremely low use of water in terms of flushing. The design should be appealing and touch more senses than only the visual.

In coastal wetlands carbon/organic matter can be stored for long periods of time thanks to, among other things, the presence of water which slows down the decomposition. Because of this, restauration and management of such habitats have the potential to decrease the emission of greenhouse gasses and help mitigate climate. Internationally these environments are called ?blue carbon? ecosystems. In Sweden, alder (Alnus glutinosa and Alnus incanata) covered wetlands along the coast is a nature type that potentially could function as a ?blue carbon? habitat.

Traditionally risk-based measures have been used to assess animal welfare in legislation and certification schemes. With increased knowledge and research, debate today tends to focus on and advocate the use of animal-based measures. However this is not a panacea for welfare and the most sound conclusion should be that assessment of animal welfare needs both. The aim of this thesis is to identify the points that need to be taken into consideration to find the optimal balance in the use of input and outcome measures according to the aim of the assessment and how these should be applied when designing a certification scheme? To answer this, a comparison of the use of resource-based, management-based and animal-based measures in two certification schemes for dairy cow welfare, Freedom Food (UK) and Svenskt Sigill (SWE), was made.

In past decades information technology has changed the conditions of organizations, not at least within the industry. Advanced IT systems have become a fact in order to cope with rapid changes in the market and to effectively manage an organization?s knowledge. When organizations became more flexible and customized expectations from customers and stakeholders also become higher. These expectations and guidelines are documented in a company?s management system, which can be designed differently depending on what standards the company chooses to implement.

Context: During the 21st century several alarming reports have been published that deals with the depletion and pollutant of the earth by human interference. The earth is an ending resource and so are the mountains and bedrocks which are continuously mined in order to harvest its minerals. The idea behind Urban Mining is to (re)invent processes enabling further purpose for materials both from old deposits and new products providing secondary raw materials and energy. This thesis aims to investigate the challenges and opportunities of how firms and organizations can and will be able to strike a better balance between product-/service systems, economic growth and environmental stewardship in the context of Urban Mining as an approach. With the innovation of processes, technology, business- planning and creation in focus.Objective: How to future proof a business model for Urban Mining by the usage of business model design.Method: This thesis will be conducted using a case study approach, meaning that it will incorporate qualitative, exploratory and descriptive characteristics - aiming towards enabling both applied and fundamental research.Results: The result evaluates the business model element differences between traditional C&D industry and Urban Mining industry.

AbstractThis is a qualitative study on what motivates personnel to apply for middle management positions within the Värmland County Police Department. This study also looks at whether or not there are differences in motivation between men and women in regards to applying for middle management positions.The study has been conducted through in-depth interviews with 17 employees of the Police Department. The material collected was analysed using the Empirical Phenomenological Method (EPP). 29 categories were generated which were then divided into four themes.The result showed that motivation can be achieved by having a more structured middle management roll whereby, for example, there are clear guidelines on the responsibility and authority you have. Support and encouragement were also named as motivating factors.

Uppsatsen är ett examensarbete på 22,5 hp, som kom till på uppdrag av SONO inredningar och Tranås skolmöbler och har utförts av Sara Storm, student på Produktdesignprogrammet vid Malmö högskola, under våren 2012. Arbetet behandlar klassrummens ljudmiljö i låg- och mellanstadieskolor samt hur elever sitter i sina stolar. Kan en elevstol bidra till en bättre ljudmiljö i klassrum och erbjuda en bra ergonomisk sittkomfort för eleven? Resultatet blev en stol, där material och konstruktionslösningar reducerar buller och med sin vippfunktion möjliggör ett flexibelt sittande..

The production of ferrochromium alloys at Vargön Alloys AB contributes to formation of unwanted ferrochromium dust, which contains toxic Cr(VI). The dust is since summer 2005 treated with an iron-sulphate solution to reduce Cr(VI) to the non-toxic Cr(III). A year later the treatment technique was improved and disposal occurs in cells on the landfill. The cells can be up to 300 m3 and the edges can be made out of fro example concrete. Tests are conducted on the treated dust when it is disposed.

This examine illustrates the section heads' and caregiving staffs' perceptions of the influence of New Public Management (NPM) in public retirement homes in Malmö. A central theme is to investigate if the main features of New Public Management are noticeable and if that's the case, are the consequences an advantage or disadvantage? The main features of New Public Management in this examine are: decentralization, competition, internal market, cost- conscious, management by objectives with a focus on results and costumer focus. To reach answers to the questions above, a quantitative and a qualitative approach has been chosen. The study is based on 41 questionnaires with enrolled nurses/nurse's assistants and four semi-structured interviews with section heads of retirement homes. Four different retirement homes have been participated in this study.
