The farming system is the basis of human existence through its production of provisions for man. By a continuous exchange of information, energy and material, between the ecosystems and the social systems, the farming system becomes an emergent property. The system's own properties, in the sense of farming methods, circulations and institutions, evolve through an adaptive process. Understanding this process and constantly learn from it, is the starting point for creating a sustainable development within farming systems. Thus, future farming system has to develop strategies that produce food provisions while at the same time takes into consideration the ecosystem's resilience and its integrity, but which also enables an ethical discussion.
The institutions within the farming system are understood as links between the ecosystems and the social systems.
Klassifikation vid de nordiska alkoholmonopolen: En jämförande undersökning av fem statliga alkoholföretags hemsidor
This thesis deals with the goods classification of the Nordic alcoholmonopolies, viz. Alko in Finland, Rúsdrekkasøla Landsins in the FaroeIslands, Systembolaget in Sweden, Vínbúðin in Iceland, andVinmonopolet in Norway. The focus of the study is the web pages of thecompanies (as they appeared April 10th 2011) and the printed pricecatalogue of Alko, from which information on class division has beenexcerpted. The emphasis lies on the division into product groups and theinformation about origin. Within these facets, which partly overlap insome of the classification systems, the principles of division and thehierarchical relations between classes are studied.
Sänkt returtemperatur : Potentiell besparing i fjärrvärmesystem
Optimizing energy systems is, in Sweden, as in many other countries, of growing interest. District heating systems are no exception. In 2012, 285 out of 290 municipals in Sweden had district heating in use and the majority of these systems have a higher return temperature than that which is possible with an error-free substation of day current technology. To, when possible, lower the return temperature is a way of increasing the effectiveness of the district heating system.This study means to investigate, through simulations and calculations, how big of a reduction in production cost a lower temperature in the city of Ystad?s district heating system would correspond to.
Biologisk mångfald i staden och dess närhet : möjligheter att som landskapsarkitekt främja biologisk mångfald
In a time of increasing urbanization the human tenure effects on the land has lead to a decrease and fragmentation of areas that are valuable to urban wildlife. These actions have had a detrimental effect on the species and habitats that exist in cities and towns.This paper investigates, through the study of relevant literature and the undertaking of interviews and field visits, the role that biodiversity plays in our society. The current attitude towards urban biodiversity and the responsibility for its promotion within the landscape architect profession has been explored.This paper includes three English case studies and a design proposal investigating how one can work to promote biodiversity on a smaller scale.This paper concludes that urban biodiversity is multi-functional ? being of ecological, social and cultural significance. The landscape architecture profession must be aware of the need to combine a variety of different factors such as economical, social and environmental aspects.
Lillån : Statusbedömning enligt EU:s ramdirektiv för vatten
In Sweden, the County Administration board is responsible for improving the water quality in lakes and watercourses according to the European Union Water Framework Directive. In Västmanland county, where river Lillån is situated, the County Administration of Västmanland have the main responsibility for the aquatic environment in that area. The knowledge about the different watercourses in the chatchment of river Lillån is today limited. The aim with this study was to evaluate the ecological quality of River Lillån based on water chemistry analyses and benthic fauna investigations. The aim was also for the benthic fauna to compere different samplingsites and sampling methods with each other in order to see how the species composition changes in the river, and to see the advantages and disadvantages with different sampling tecniques.
Uppföljning och analys av Stockholms stads solcellsanläggningar
During 2007 the City of Stockholm installed five grid connected photovoltaic systems. The aim of this master thesis is to quantify the amount of produced energy and recommend routines to collect and analyse production data, to make production data accessible by the public and to gain experience for future installations.The total amount of produced energy until March 2009 is 227 000 kWh, with an annual rate of 150 000 kWh. The expected annual rate was 148 000 kWh.All system owners are positive about their plants and see economical benefits in scaling up such systems.The installations need very little attendance and maintenance, however it is recommended that an alarm function is installed for automatic feedback in case of a system failure. All future systems should be inspected during full operation to determine if the actual capacity is matching the installed capacity..
Utvärdering av digitala provtryckssystem
Six different Digital Proofing Systems from three different techniques have been evaluated as totechnique, printing quality, economy and usability. Digital proof from two paper qualities, coatedand uncoated, has been compared with references printed in offset, to see how good they match eachother. Only two Proofing Systems manage to print on reference paper. The other Proofing Systemsuse special paper for digital proof.Measurements and visuell judgement show that the Digital Proofing Systems visualise referencepictures with quite good quality. Proof optimised for coated paper visualise the colours with goodresult.
Färdplanen & Genèveinitiativet : Förutsättningar för framsteg i den palestinsk-israeliska fredsprocessen
The aim of this paper is to examine if the two latest Peace Plans in the Palestine-Israeli con-flict observes the sources of the conflict and presents measures in the purpose of solving them. The point of departure is William Azar?s theory of protracted social conflict (PSC). According to Azar, the internal sources of a PSC lies in three clusters of variables: the com-munal content of a society, the deprivation of human needs as an underlying source of PSC, and the role of the state in the deprivation or satisfaction of human needs. The study is de-signed as a multiple-case study where the units of analysis are the Roadmap to Peace and the Geneva Initiative.
Termomekanisk analys av svarvstål : Volvo Aero Corporation
Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.
Hur hanterar institutioner en miljö med blandade Operativsystem?
The purpose of this thesis is to investigate if there are environments that use
some kind of central authentication system within institutions/schools. The
hypothesis is that an institution not using a form of central authentication
service has more need for maintenance and as such is considered a higher cost
for the organization.

working today has been done, with emphasize on the hypothesis..
Toddlare och demokratiarbete : om inflytande och delaktighet hos förskolans yngsta
The purpose of this study was to find out how young children are allowed to influence and affect their daily lives in preschools, as well as teachers? views on the latter. My interest in this topic is born out of my experience of working with both younger and older preschool children. My view is that democratic work with older children is largely based on direct verbal communication while with toddlers it is based on an adult?s interpretation of a child?s often non-verbal expressions.
Fördjupad miljöriskbedömning av förorenade markekologiska system. : Integrering av kemisk, toxikologisk och ekologisk information.
AbstractThe research project Liberation, supported by the European Commission under the Environment and Sustainable Development Programme (Fifth RTD Framework Programme) aimed at developing a decision support system for ecological risk assessment of contaminated sites has proposed a tiered system including the triad method. This method integrates contaminant chemistry and bioavailability analyses with observed ecotoxicological effects in soil and groundwater. In this study the triad method was used to perform a risk characterization of a former surface treatment and metal industry, now used for the student union buildings of the Mälardalen University in Eskilstuna, Sweden. On the site, high concentrations of copper, zinc and nickel have been detected in the soil in a preliminary investigation of contaminant levels with XRF. For performing the risk assessment of the site according to the triad method, contaminant bioavailability, soil metal concentrations and soil toxicity were determined and an ecological assessment was carried out on four selected soil samples (one reference soil and three samples with low (B), medium (C) and high (D) contaminant levels). Contaminant bioavailability was measured through leaching (ISO TC 190/S7) and biouptake tests (DGT).
Socialt kapital på arbetsmarknaden - En möjlig väg ut?
People are constantly using there friends in order to ask for a favor or to get hold of some information. This is usually done unconsciously and it is just viewed as everyday life behavior. The function and the use of these links definitely have a value, which means that it can be viewed as a form of capital. But this capital is not caught in the traditional theories of physical capital or human capital; it demands it?s on theorization.
Är det värt att tävla: En studie av affärsplanstävlingens roll för den tidiga entreprenören
Business plan competitions have long been used as a mean for entrepreneurial organizations and Universities to educate students in entrepreneurship. But what's in it for the entrepreneur This thesis aim is to understand what utility business plan competitions have for the participating entrepreneurs. It consists of interviews with Swedish entrepreneurs at various stages in the entrepreneurial process, who has participated in business plan competitions to get ahead. The conclusions of the study are that business plan competitions are good for the entrepreneur from a motivational and developmental perspective but not from a financial perspective..
Mikroproducenternas påverkan på Elinorr
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.
