Utveckling och tillämpning av en GIS-baserad hydrologisk modell
A distributed hydrological rainfall-runoff model has been developed using a GIS integrated with a dynamic programming module (PCRaster). The model has been developed within the framework of the EU-project TWINBAS at IVL Swedish Environmental Research Institute, and is intended for use in WATSHMAN ? a tool for watershed management developed at IVL. The model simulates runoff from a catchment based on daily mean values of temperature and precipitation. The GIS input data consist of maps with soil type, land-use, lakes, rivers and a digital elevation model.
Livets skillnader : Heidegger, djuret och vetenskapen
This essay constitutes an attempt to expose, with reference to contemporary animal research, the limits of Martin Heidegger?s concept of the being of animality in Die Grundbegriffe der Metaphysik (1929/30) and to propose some possible ways to think, within the philosophical style of this particular work, the being of those animals that most distinctly transcends Heidegger?s concept. The essay seeks to address the following question: Do the results of contemporary animal research expose ways of being within animality that withdrawal from Heidegger?s concept of the being of animality in general, and if so, how should we think these new ways of animal being? The motivation to ask this question, I argue, are immanent to Heidegger?s thinking in at least three ways: 1) Because of his standpoint that philosophy cannot, in any meaningful way, create an ontological concept of animality without an orientation towards the results of the positive sciences; 2) Because of the unfinished and tentative character of Heidegger?s analysis, a character that is such that it should be seen, according to Heidegger himself, as an essential point of departure for further thinking; 3) Because of Heidegger?s view that the being of the animal are such that it involves the withdrawal of this very being from any originary access, a withdrawal that necessitates an infinite return to the question concerning the being of the animal. The essay wants to be a continuation of lines that are present in Heidegger?s open-ended thought on this theme rather than to be an external critique that approach the text, which is most often the case, as a closed point of view which we are forced to affirm or reject.
Kvalitetssäkring av stordimensionella gjutgods : Produktion och kontroll av formgjutna komponenter
AbstractA continuous improvement of products and production is an important goal for a modern industrial company. A small engineering group located in Sweden came in touch with the authors of this report during the spring semester of 2014. The aim of this report is, as part of the group´s ambition of improvement, to analyse ways in which the quality of component casted parts can be verified. Non-destructive testing (NDT), and methods to use it for quality control, is the main focus of this report. However, fields such as material standards, component casting and quality engineering are analysed as well.
Livscykelbaserad miljövärdering av en ny kontorsbyggnad : En jämförande studie mellan två analysmetoder
This Master?s Thesis aims to illustrate in what ways the two Swedish environmental assessment tools, the Environmental Load Profile and EcoEffect differ and if performed valuations gives different results and environmental goals.The built urban environment causes about half the environmental loading in Sweden. The society?s ambition towards sustainable development has resulted in demands reducing the environmental load. One way to accomplish this change is with the assistance of tools for environmental assessment of the built environment.
Verksamhetsstyrning med fokus på intressenters och medarbetares betydelse : ett fundament för företagens varaktiga framgång?
We would like to gain a more in depth knowledge of whether the modern orientations both within corporate governance and control philosophy lay the foundation for enterprises? more sustainable success. These both modern orientations are increasingly focusing on the importance of enterprises? setting of goals and visions on the basis of stake holders? interests and the employees? more active engagement in and motivation for the goal achievement. Despite these common inherent characteristics, it is not evident from current scientific debate how such integration actually emerges in the control philosophies of the enterprises.

Det moderna goda boendet. Ekologiskt hållbara konceptlösningar.
Problemet med dagens standard för hygienrum och dess komponenter är att de baseras helt på tillgänglighet. Vilket i och för sig är en bra sak, sett utifrån att fler personer kan ha möjligheten att utnyttja bostadsfunktionerna även om de har vissa rörelsehinder. Men vi vill ta steget längre, inte endast se till tillgänglighet utan även se till vad som kan uppskattas, för att höja levnadsstandarden och uppskattningen av våra hem. Den svenska standarden är som tidigare nämnt baserad på tillgänglighet och är inte alltid anpassningsbar till nya lösningar och komponenter som kan förekomma i badrum, vissa saker ändras, får nya funktioner, kanske utökade användningsområden. Syftet är att försöka utöka möjligheten att nå högre kvalité för badrummet och samtidigt försöka se till de alternativa lösningarna som kan åstadkommas idag.
Manfred Björkquist och Nathan Söderblom i den kyrkopolitiska debatten, : speglad i deras brevväxling 1914-1931

Vermicompost for reduction of vegetable waste - and a possible means to produce fish feed in aquaponic systems?
Aquaponics is a food production system consisting of a consecutive cultivation of plants and aquatic animals, fish or shellfish, in recirculating water. The plants feed on the nutritious effluents from the fish tank and bacteria converts ammonia from the fish tank into nitrate that is absorbed by the plants. The plants receive nutrition and the fish gain purified water.
The environmental impact of the production of fish meal and fish oil used in conventional fish feed includes a large consumption of fossil fuels with subsequent carbon dioxide emission.
The aquaponic system can be made environmentally sustainable and self-supporting if supplemented with a vermicompost/vermiculture for the production of worm protein as a fish feed.
Vegetable waste from the hydroponic part of the system can be reused as worm feed in the compost and the protein rich worms can be harvested, dried and grinded and brought back to the aquaculture as fish feed.
As a first step in this direction, I have investigated the effect of recycling of vegetable waste in vermicomposts on the growth and number of earthworms (this was evaluated after harvesting).
The hypotheses were that earthworms can be cultivated in the vegetable waste and that by adding manure to the vermicompost it is possible to obtain a nutrient content adequate to support a continuous worm harvest, in other words create a vermiculture.
Eisenia fetida and Dendrobaena veneta were grown in 20 L bins containing peat mixed with either poultry or cattle manure. The proportions were 70% peat and 30 % manure. Discarded plant parts from lettuce cultivation was added to the vermicomposts (35 g per week) and water was supplied
with 0.8 L per week.
Handel med utsläppsrätter - hur företagsstrategier påverkas :
Climate change is one of the most difficult problems that humans have to deal with. Today, the evidence of human effects on the climate change and the rise of temperature on earth are strong. It is extremely important that all countries get together and cooperate in order to be able to solve the problem with climate change. One step in the work on climate changes is the Convention on Climate Change, which was agreed on in 1992. The Convention on Climate Change resulted in the Kyoto Protocol in 1997.
The Kyoto Protocol is an agreement between a number of industrialized countries to limit or reduce the green gas emissions.
Grönstrukturplanering i det skånska slättlandskapet?
The ongoing change that characterizes the landscape as a result of the development of the society as a wholeis the basis for this thesis. Even though the Scanian landscape still is dominated by arable land, other valuessuch as biological diversity, cultural heritage and economical aspects, has all been ascribed the landscape asmore and more important factors and in some respects, compete with the farming industry about the right tothe landscape. Our demand of more and more space, will of course also affect the landscape. Huge amountof land are used to build external malls and single-family houses, which gives rise to an increasing need foran extended transport system that also is land consuming.It all comes down to: how the municipalities deal with non built areas - the green structure. Do themunicipalities have separate programs describing their vision and objectives concerning the green structure?Literature studies, an inventory made of the municipality programs in the west and south west of Scaniaand interviews with employees at the municipalities clarifies the use of the green structure concept, both intheory and in practice.The green structure concept seems to be derived from the environmental debate.
SARS
SARS [Severe Acute Respiratory Syndrome] penetrated China in spring of 2003, created havoc in the social society, exposed weaknesses within the political system and pushed the nation towards a crisis of confidence. At the same time the crisis revitalised the Party's position, brought people from different social stratum together and had a beneficial impact on the populace's knowledge on health related issues.What makes the SARS crisis in China interesting for further and deeper investigation is the method it chose to respond to its national crisis. They plan of response was indeed a retrogression back to "older" times, using methods and propaganda very much like those used during Mao Zedong and later Deng Xiaoping. The first step of response was denial and cover up of the real situation, which quickly turned to unprecedented transparency, as the magnitude of SARS became known. The Party and the government were quick to proclaim themselves as the bearer of the key knowledge and information on how to best fight the disease, this in sharp contrast to the political trend of more co-operation between the private and public sector and political transparency.
Miljöcertifierade kommersiella byggnader : Undersökning av ekonomisk ansvarsfördelning mellan hyresgäst och fastighetsägare
The Swedish commercial real estate market is in the current situation globally affected and is actively interacting with the rental and capital markets through international tenants and investors who are setting new demands on the property owners. The European Union has set new requirements as well in purpose of reducing humanity?s negative effect on the climate and therefore the international real estate market has introduced Green Building-certificates in order to decrease the real estate industry?s environmental impact.Certificated buildings with low energy consumption are a more common sight in Sweden these days. The development, however, could go even faster if there was not certain difficulties between property owners and tenants. Previous research has revealed that tenants do not always have knowledge about, or may have access to the economic benefits that a green building can provide.
Virala nyheter: Hur nyheter sprids och bemöts i sociala medier
AbstractBakgrund: När människor tar del av nyheter via sociala medier som Twitter och Facebook ärdet möjligt för andra användare i de sociala medierna att påverka uppfattningen av innehållet.Det kan exempelvis ske genom att lyfta fram, tona ned, omtolka eller omgestalta nyheterna.Hur detta sker och vad det får för konsekvenser för hur människor uppfattar nyheterna hartidigare inte undersökts. Dessutom saknas det kunskaper om vilka nyheter från massmediernasom sprids i social medier, i synnerhet i Sverige.Syfte: Beskriva och jämföra vilka nyheter som sprids i sociala medier (Facebook och Twitter)samt undersöka de psykologiska orsakerna till varför de sprids vidare.Metod: Artiklar (N = 89 450) från de tolv största svenska nyhetssajterna under två månader ibörjan av 2014 undersöktes hur de spreds på Facebook och Twitter med en kvantitativinnehållsanalys. Två oberoende experiment (N = 311) undersökte effekten av kritik på nyheter, inbäddade i Twittermeddelanden, samt effekten av antalet retweets (vidarebefordringar) på fortsatt vidarespridning.Resultat: Majoriteten av de mest delade artiklarna på Twitter handlade om ett fåtal ämnen (rasism, extremism, feminism och välfärd). 17 procent av artiklarna hade delats minst tio gånger på Facebook eller Twitter. Artiklar delades i regel tio gånger mer på Facebook än på Twitter.
Sambandet mellan hästens huvud/halsposition och ryttarens rörelse i sadeln :
Dressage schooling is not a subject that rests on science, it is a matter of dependable experience. So far there hasn?t been so much research about it, but more and more is done. Especially the interaction between rider and horse is a nearly uninvestigated field. Riding skills is much about having the right position, and having the horses head and neck in different positions, but there are no research done that support or deny that this old ?knowledge? is for the best for the horse.
This study was performed to evaluate if the head and neck position of the horse, and the velocity, has any influence on the position of the rider.
