Gestaltning av en takträdgård
Gastric ulcer is a common disease among pigs in the whole world where an intensiveproduction occurs. It is mainly the upper region, the nonglandular region of the stomach thatis affected. Gastric ulceration is a disease with several risk factors. The factor that seems tohave the largest impact on the development of gastric ulceration is a small particle size of thefeed. The reported prevalence of gastric ulceration differs from 5 to 100 % and it is a largeherd-to-herd variation.

Environmental impact assessment of energy recovery from food waste in Singapore : comparing biogas production to incineration
As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.
GNSS-Styrning : Information för platschefer
An investigation of the heat impact of laser cutting on the material properties when producing tensile and impact test specimens of different steel types of varying thickness has been performed. The purpose of the thesis project was to provide recommendations regarding how much material that needs to be milled from the laser cut edge before tensile and impact tests. The study has been performed partly by investigating the test specimens by heat camera when the specimens were cut in the laser cutting line and partly by performing hardness tests, investigation by microscopy, and tolerance and roughness measurements and tensile tests of the laser cut material and material produced in the traditional multi operation machine. The results show that the heat affected zone in the thicker materials is greater than previously thought of, and that the currently used recommendation has to be adjusted. The study clearly shows that the thicker the material, the greater the heat affected zone, independently of the steel type, since the thicker material takes longer time to cut.

Detta examensarbete är utfört på plats i Lajaedo, Brasilien och i anslutning till Sanitário de Lajeado ? RS, Brasilien, mellan januari till maj 2010. I samband med denna rapport utfördes två andra examensarbeten inom samma områden. Det är menat att denna rapport skall ligga till grund för framtida projekt och beslut om utökad lakvattenrening.Lajeado ligger i södra Brasilien ca 100 km från atlantkusten. 10 km utanför Lajeado ligger en ung avfallsdeponi på ca 15 000 m2 till ytan med tillhörande lakvattenrening med ett utjämningsmagasin, en syrsättningsbassäng samt sedimentering.
Vintervegetation genom ljus : om hur man med belysning kan framhäva avlövad vegetation i offentlig stadsmiljö
Use of lighting is crucial to make public urban
places available during dark hours. Landscape
architects participate in planning of lighting, but
during our education there is very little taught on
the subject. Through this study we approach the
subject of lighting by looking into lighting methods
for urban plant materials during winter.
In this thesis we look into ways to emphasize the
visible characters and experiences of urban plants
during winter season using light. Target audience
are landscape architect students and landscape
architects without knowledge of lighting. The part
of the thesis that describe basic conditions for, and
visual characters of plants can be useful to lighting
designers without knowledge in this subject.
Working methods used were the following:
? Pre-study about light and lighting techniques
through literature and dialogues.
? Compiling important visual winter plant
characters through photography and literature.
? Outdoor light experiments with plants.

Undersökning av sambandet mellan strålningstemperatur och NDVI i Sahel
Several studies have analysed the relationship between Normalised DifferenceVegetation Index (NDVI) and radiative surface temperature. A main goal for moststudies have been to find the best method for carrying out land cover classificationsand to study land cover changes, based on a combination between the twoparameters. Since atmospheric components have a significant influence on bothparameters, most applications were based on multi-temporal data. The quality of theindividual values in such a combination is improved, but the biophysical justificationis uncertain. This study presents a different method, based on only the combination ofvalues that have been registered the same day and about the same time of the day.125 daily images of NDVI and 250 images of radiometric temperature were used inorder to analyse the relationship between (1) NDVI and radiative temperature and (2)NDVI and relative temperature difference between early morning and mid-day.Results between NDVI and radiative temperature show a significant negativecorrelation on areas where a distinct growing season develops, and a strong positivcorrelation where vegetation is abscent throghout the season.
Det Gröna Torget - Omgestaltning av Ronneby Torg
Ronneby torg är beläget centralt i Ronneby stadskärna i sydöstra Blekinge. På
denna plats går det att identifiera tre problem som utgör brist på människor
(social hållbarhet), rumslighet (mötesplats) och vegetation (ekologisk
hållbarhet). Tidigare har torgets södra del innefattat en stadspark vid namn
?Gröna Torget? medan hela torget idag utgörs av en hårdgjord yta med inslag av
träd i dess kanter. Det finns ett behov från Ronneby kommun att utveckla torget
som en mötesplats, då kommunen utlyst en förslagstävling av just denna
anledning.
Träning och ekonomiskt beteende: ? Effekterna av konditionsträning på överkonfidens, riskbenägenhet och välbefinnande
It is well proven that physical exercise has an impact on our bodies as well as our minds. The aim of this study is to examine if this impact also affects economic behaviour. Three hypotheses regarding the impact of acute exercise on overconfidence, risk enhancement and well-being have been tested by collecting questionnaires from 364 participants at Friskis & Svettis, Kungsholmen who all were asked to answer the questions either before or after exercising. The differences between the before and after group were analysed, indicating small increases in all three test areas after exercising. These increases were, however, not large enough to reject any of the null-hypotheses of zero effect on the given five per cent significance level.
Investeringar och tillväxt ? vilka faktorer påverkar? : En longitudinell studie av tillverkande företags investeringspraxis och tillväxt över tid
Background: Research about capital budgeting is under constant development. Several researchers developed the research about capital budgeting late in the 20th century. This development shows how companies' internal and external factors and other circumstances have an impact on companies? capital budgeting practice. It has also been shown that there are links between companies capital budgeting and their growth.
Svamparnas roller i svenska barrskogsekosystem : hur ser kunskapsläget ut hos några olika grupper människor?
Fungi are everywhere around us and recently, there has been
an increased interest in their role and importance in the forest.
The fungi have several strategies to acquire energy and nutrition; one example is a mutual symbiosis with trees and plants - another being dissolving organic materials.
Attempts have been made to better understand the circulation of nutrition in coniferous forests, and how fungi cooperate.
Trees and plants have adapted with mycorrhizae and are now interdependent which is important to consider in forestry.
A great number of fungi depend on dead wood and old trees to set fruiting bodies and spread further. These fungi also create environments for other species, such as birds and insects.
The vegetation of a forest is determined by a series of factors; tree species, how old the forest is, soil type, as well as the ability of the fungal spores to spread and establish. Furthermore, in determining vegetation, the fungi?s ability to compete in the soil matters. These factors are nearly unexplored.
Researching fungi knowledge and interest, a survey was distributed to five groups of people.
The groups included forest owners, high school teachers, high school students, senior citizens, and a fifth group - ?o he ? - consisting of people of mixed ages and backgrounds.
Miljöpåverkansbedömning vid tillverkning av etanol från cellulosabaserade råvaror : ekologisk gård självförsörjande med drivmedel
Fuel produced from renewable resources is of big interest. In this project the difference between a few different renewable materials are compared on the matter of environmental load when ethanol is produced. The renewable materials that are compared are Salix, straw and reed canary-grass (rörflen). The cellulose in the material is cut down to small pieces and then hydrolysed so that the sugar from the cellulose can be fermented into ethanol.
Tha amount of ethanols that is studied in this work is the smount of ethanol needed to cultivate 1000 ha. The functional unit in the report is 1000 ha.
?If we zigzag in the middle, it?s OK? : En fältstudie som undersöker turismens påverkan på balinesisk religion och kultur
[?If we zigzag in the middle, it?s OK?] The purpose of the following study is to examine the relationship between tourism and religion in a Balinese context. We look specifically at changes in religious practice, culture and mentality, as well as how religious philosophy is used as a tool for limiting the negative impact of tourism. The methods used are semi-structured interviews and participant observations. Central themes in the following essay are globalization in the form of tourism, westernization, subsystem theory and capitalism, which also make up the theoretical framework.
Styrelsen och samhällsansvaret - En studie om hur styrelsesammansättningen påverkar CSR-prestation i svenska börsbolag
The composition of the board of directors and Corporate Social Responsibility (CSR) are two widely researched subject and discussed by the media. This study aims to examine the impact of the board of directors' composition on CSR performance among the largest companies listed on Nasdaq OMX stock exchange 2008 in Stockholm, Sweden. A linear regression analysis is applied to investigate the relationship and evidence is found that board attributes have an effect on CSR performance. Among these; the size of the board, outside directors and employee representatives all have a positive impact on environmental performance. Furthermore; female, outside directors and employee representatives have a positive impact on social performance.
