Evaluation and Comparison of Ecological Models Simulating Nitrogen Processes in Treatment Wetlands,Implemented in Modelica

Two ecological models of nitrogen processes in treatment wetlands have been evaluated and compared. These models have been implemented, simulated, and visualized in the Modelica language. The differences and similarities between the Modelica modeling environment used in this thesis and other environments or tools for ecological modeling have been evaluated. The modeling tools evaluated are PowerSim, Simile, Stella, the MathModelica Model Editor, and WEST. The evaluation and the analysis have been performed using McCall?s factors for software quality (McCall et al, 1977), a correlation analysis and the Constant Comparative Method (Glaser&Strauss, 1999).

Leanbana till toppen - En studie om Lean-implementering i skidsystem

The ski resort is a business unlike any other. While providing the customer with a service, it produces the service in a manner that in many respects resemble the traditional producing company. Therefore, since the challenges facing the ski resort are a mixture of what can be found in these different environments, this study aims to investigate the applicability of Lean principles in this context. With a qualitative approach based on direct observation, combined with survey data from 2819 respondents, we evaluate the expected effects on customer value of ten commonly defined Lean principles. The study finds that although Lean theory can help disseminate customers throughout the resort and provide greater transparency, the nature of the operations calls for caution.

Störningsregimer vid Skövde övnings- och skjutfält : Stridsfordons påverkan på olika naturtyper i militära övningsområden

A lot of habitats have declined or disappeared as the old cultural landscape changed to the modern agricultural landscape of today. Places such as power line corridors, racing tracks, gravel pits and military training sites have become refuges for many species associated with the old cultural landscape. These sites have been exposed to ecological disturbances that create the same type of habitats that were found in the old cultural landscape.The military training sites in Sweden has an impressive diversity of species. Disturbances from the military exercises have created habitats that are important for a wide range of species.The purpose of this thesis is to study some of the ecological disturbances occurring in the military training sites of the Swedish Armed Forces and examine how they affect different types of habitats. The thesis explains through litterateur and field studies the reason to the rich biodiversity often found at military training sites.

Den ekologiskt hållbara staden : en diskursanalytisk studie av styrningspraktiker i Hammarby Sjöstad

The study is based on critical discourse analysis The result of this study is that the ecological investment in Hammarby Sjöstad partly constitutes a hidden exercise of power, taking shape as built-in physical measures in the dwellings and the neighbouring surroundings.

GRAFISK PROFIL TILL EN BLOMSTERHANDEL - corporate identity for a flower shop

This project aims to explore how to create a working concept-based flower shop visual identity, with focus on brandig, eco-branding and visual communication. My main question is: How do I create effective visual communication for an ecological flower shop? The results of this thesis are that there are things to consider when creating a visual identity with an ecological concept. The most important question is if there is any benefit for your company to go green, otherwise positioning of your company will be hard. What I realized during the design part of my project was that if I use the methods described in this thesis and consequently applying my choices after the flower shops identifying words, a working concept-based visual identity will be possible to create..

Hållbar utveckling- En textanalys av miljöpolicy i lokal och nationell kontext

Sustainable development is a concept that has been interpreted in a multitude of ways in different contexts. This essay argues that the discourse of "ecological modernization" has strongly influenced the way in which the concept of ?sustainability? has been constructed in Swedish environmental policy. This interpretation of the concept of sustainability offers the possibility of combining economic growth with ecological sustainability which stands in contrast to the assumptions of Deep Ecology and Green Theory. The aim of this essay is to explore how the concept of sustainability is being formulated in environmental policy both on a national level and in the city of Malmö.Considering these issues in a specific context, this essay focuses on city planning that is as an important instrument to promote urban sustainability both on national and local levels.

Ekologisk hållbarhet i den fysiska planeringen, teori till handling :

I wrote this essay with the aim to explore, understand and get some insights into what it is that effects the possibilities to plan for ecological sustainability and make it happen. There is no clear definition of sustainable development but world top meetings and reports have developed goals and strategies. I will present some of the theory at hand but most of this essay is based on six interviews with planners at local governments from around the country. Several of the local governments are using the goals issued by the state government by putting them into their large scale plans. During the interviews some obstacles were identified, like a lack of resourses, disadvantaging powerstruktures, conflicts with marketeconomy and simply different meenings about what ecological sustainability is in practice. My method of getting information through interviews and documenting them by taking notes had, as all methods, it?s weakneses.

Internetetik på bibliotek

The aim of this issue is to study how Swedish public libraries deal with the principles of freedom of speech and freedom of information in connection with public use of the Internet. The authors intention has been to find out whether the public use of the Internet has caused ethical problems for library workers and how the libraries solve situations when they consider their principles violated by library users. The authors study the debate on the issue in a couple of Swedish library magazines published during the late 1990s and they also give a few examples from the USA during the same period. They study the ethical principles and directives for schools published by the Swedish Board of Education as they claim that many of the public library users are students who bring along their ethical conceptions and thereby affect the ethical climate of the libraries. In their study the authors refer to ethical rules given to librarians by their trade union DIK and to the conclusions drawn from the hearing Good Ethics on the Net held by the Swedish IT Commission in 1998.

I den bästa av världar? är kvalitet lika för alla? : intervjuer med politiker och enhetschefer inom äldreomsorgen

The purpose of this study was to examine and describe how politicians and directors of care define and experience quality in aged care facilities. Further on we wanted to compare on which fundamental principles the participants base their opinion about quality and how they work with quality. To reach our aim we conducted five interviews with politicians and directors of care. The results show that it is hard to determine quality in an unambiguous and objective way. Quality in aged care appears to be about relations and encounters amongst people.

Hållbar utveckling och CSR inom foderindustrin för hund och katt : Med fokus på det ekologiska perspektivet

Pets like dogs and cats have a considerable importance for humans and research demonstrate a variety of positive economic and social effects in society due to our pet companions. The presences of pets are increasing on a global scale with correlation to economic development in low- and middle income countries. For example dogs have doubled in India over a five year period. The feed industry for dogs and cats is also the fastest growing sector in the food industry and certain pets have a significant animal protein intake which, depending on the choice of resources may provide a high ecological footprint. Examples of environmental effects with distribution and manufacturing of pet food are increased greenhouse gas emissions, waste, use of water and energy.

Läkemedlet Oxazepam påverkar abborryngel : Exponering under embryonalutvecklingen ger effekter på tillväxt, överlevnad och beteende

Pharmaceuticals are environmental pollutants that are a major threat to aquatic ecosystems and very little is known about their ecological consequences. In this study growth, survival and behaviour (sociability, activity and boldness) of perch fry (Perca fluviatilis) were examined in order to study the possible effects of exposure to a benzodiazepine anxiolytic drug, Oxazepam, during embryonic development. The study tested following hypotheses: (1) perch growth is affected positively by exposure during embryonic development; (2) early perch survival is affected positively by exposure during embryonic development; and (3) boldness and activity increases while sociability decreases in perch fry exposed during embryonic development. Embryos of naturally spawned perch were exposed to water with two different concentrations of Oxazepam. The embryos were exposed during different parts (24-hour periods) of the embryonic development, because embryos may be more vulnerable at certain times during embryonic development and/or because the exposure at different times can produce different effects.
