31	Att rädda Sara Sand : En deleuziansk läsning av Stina Aronsons experimentella verk Berlin, Denise January 2019 (has links) This thesis explores the creative function of the pseudonym Sara Sand, used by the author Stina Aronson for four literary works in the late 1920s and early 1930s. Två herrar blev nöjda (Two gentlemen were content), Fabeln om Valentin (The tale of Valentin), Tolv hav (Twelve oceans) and Syskonbädd (Siblingbed) are modernist and experimental works that I approach with an experimental way of reading. In order to emphasize what I find to be an inherent strive for freedom within these texts, I draw from Gilles Deleuze and Félix Guattaris notion of desire as a productive force and their view of the text as a rhizomatic structure, as presented in Anti-Oedipus (1972) and A Thousand Plateaus (1980). The characters in Sara Sands writing are in constant movement and in continuous processes of becomings which challenges any kind of fixity, whether that be social structures and hegemonic discourses or simply the individual self.

För låga grundvattennivåer i grundvattenmagasin, kan bland annat leda till saltvatteninträngning i dricksvattenbrunnar. Syftet med studien var att fastställa om topografi, avstånd till hav, brunnsdjup, jorddjup och jordart är kopplat till kloridhalter i dricksvatten, att undersöka om och vad det finns för risker för saltvatteninträngning i ett framtida förändrat klimat, av klimatförändringar, samt om det finns några åtgärder mot saltvatteninträngning. Korrelationstestet Kendall’s tau användes för att undersöka om det fanns en signifikant korrelation mellan kloridhalter och topografi, avstånd till hav, brunnsdjup och jorddjup och Wilcoxon rank sum test användes för att undersöka om det fanns någon signifikant skillnad mellan de olika jordarterna. I denna studie fastställdes negativ korrelation mellan kloridhalter och avstånd till hav (p=0,000341), samt kloridhalter och topografi (p=0,0124). Studien visade på att det inte fanns någon signifikant korrelation mellan kloridhalter och resterande parametrar, vilket tidigare forskning dock indikerar. Vad gäller brunnsdjup, fanns en signifikant korrelation mellan topografi och brunnsdjup, vilket kan tyda på att brunnar generellt är borrade grundare i låglänta områden. Gällande jorddjupet kopplat till kloridhalter, antogs det vara för tunt (cirka en meter) för att kunna se något tydligt resultat av korrelationstestet, då ett för tunt jordlager inte påverkar grundvattenbildningen i tillräckligt stor utsträckning. Detta bidrog även till att det inte fanns någon signifikant skillnad mellan jordarterna. För den andra delen av studien utformades en modell i Matlab, för att undersöka om och hur klimat- förändringar kommer påverka grundvattennivåförändring och därmed även saltvatteninträngning. Referensperioden var 2004-2020 och framtidsscenariona var RCP4.5 och RCP8.5, vilka delades upp i två olika perioder: 2021-2060 och 2061-2099. Modellen visade på att grundvattennivåer blir lägre i ett framtida påverkat klimat, vilket kan tyda på att det är en större risk för saltvatteninträngning. Dock fanns det många osäkerheter och modellen skulle kunna göras mer nyanserad. För den tredje delen av studien gjordes en litteraturstudie där sju olika åtgärder undersöktes: kontrollering av grundvattenuttag, vattensnåla åtgärder i hemmet, att borra grundare brunnar i riskområden, anslutning till kommunalt vatten, omvänd osmos, ADR (abstraction, desalination, recharge) och SWT (subsurface water technologies). Dessa jämfördes därefter mot varandra genom att ställa upp för- och nackdelar för alla åtgärder. Överlag är förebyggande åtgärder att föredra, dock tycks SWT eller ADR vara bättre än omvänd osmos för redan kontaminerat vatten. / Just over one million inhabitants in Sweden are dependent on individual drinking water supply from groundwater. When the groundwater levels are too low in a groundwater reservoir, it can lead to saltwater intrusion in drinking water wells. The purpose of this study was to establish whether topography, distance to sea, well depth, soil depth and type of soil correlated with chloride in drinking water, to investigate whether there is a risk for saltwater intrusion in a future changed climate, due to climate change, and to investigate if there are any measures to minimize saltwater intrusion. Kendall’s tau was used to investigate if there were any significant correlations between chloride and topography, distance to sea, well depth and soil depth. Wilcoxon rank sum test was used to investigate if there was a significant difference between the soil types. In this study the results only showed a significant correlation between chloride and distance to sea (p=0,000341) and between chloride and topography (p=0,0124). There was no significant correlation between chloride and the rest of the parameters. However, earlier research has shown that there is a correlation between chloride and all previous mentioned parameters. There was a significant correlation between topography and well depth, which can imply that the wells are drilled shallower in lowland areas. Regarding the soil depth connected to chloride, it is assumed that the soil depth is too thin (about one meter) to see any clear results, since a shallow soil depth won’t affect the groundwater recharge enough. This could also contribute to no significant difference between chloride and soil types. For the second part of the study a model was built in Matlab, to investigate if and how climate change will affect changes in groundwater levels and therefore if it will influence saltwater intrusion. The reference period was 2004-2020 and the future scenarios were RCP4.5 and RCP8.5, which were divided into two periods: 2021-2060 and 2061-2099. The model showed lower groundwater levels in the future, which can imply there is a greater risk of saltwater intrusion. Although there are multiple limitations and the model could be made more nuanced. For the third part of this study, a literature study was made, where seven different measures where investigated: to control groundwater abstraction, to install waterefficient techniques in households, to drill shallower wells in risk areas, reversed osmosis, ADR (abstraction, desalination, recharge) and SWT (subsurface water technologies). These were compared to each other, where advantages and disadvantages were balanced against each other. Overall, preventative measures are preferable, although SWT and ADR are better than reversed osmosis for already contaminated water.

33	Hur Biofouling Påverkar Östersjön : En allmän litteraturstudie / How Biofouling Affects the Baltic Sea : A general literature study Eliasson, Emil, Dahl, William January 2023 (has links) The aim of this literature study was to investigate the effects of biofouling in the Baltic Sea. This was done to increase environmental awareness and understanding of the importance of a sustainable marine environment. A systematic search in selected databases resulted in the study being based on tio research articles. The overall results of the study show that biofouling demonstrate negative effects, but the effects are not fully understood to date and the focus is still on economic aspects. Furthermore, it was observed that the studied organizations are currently focused on greenhouse gas issues, but they have also been paying attention to biofouling problems in recent time. The literature study provides important insights into the effects of biofouling. biofouling aquatic species invasive alien species ship hull vessel ship Baltic sea Baltic natural environment new research Ekosystem Fartygsskrov Hav Biofouling Biologisk påväxt Östersjön Organisationer Invasiva arter Maritim miljö Fartyg Påväxt Ecology Ekologi
34	Ocean acidification effects on marine organisms : a study of Littorina littorea and Balanus improvisus Domeij Hilliges, Isak, Stendahl, Cecilia January 2011 (has links) The world’s oceans are becoming more acid in a process called ocean acidification. The pH of the ocean have already decreased by 0.1 units from pre-industrial time until today. Scientists predict that by the year of 2100 the pH will decrease by as much as 0.4 units. This is a big potential problem to many marine species, because they have developed in such a stable environment that has not changed for millions of years. It is difficult to predict how they might be affected by such a decrease in pH during a relatively short time period. Several studies have been made on marine species exposed to decreased pH-levels, the results showed changes in their physiology but it is hard to predict how these changes will affect the organism in a long-term scale and if this might change ecosystem dynamics. Our study measured the activity of Littorina littorea and Balanus improvisus when exposed to lower pH, the results of our study showed an increase in activity for the lower pH (pH 6.0-7.5) when compared to the control (~pH8). The area of ocean acidification is a field that requires further studies to fully understand its effects on the marine ecosystems and the species within it. ocean accidification accidification pH sea marine organism marine littorina littorea balanus improvisus periwinkle barnacle CO2 acid ecosystem activity cirral movement calcium carbonate system buffering low pH havsförsurning försurning pH hav marina organismer marin littorina littorea balanus improvisus havstulpan strandsnäcka CO2 surt ekosystem aktivitet cirrala rörelser buffrande lågt pH

36	Dr. Eleine Mad Jacobsson, Madeleine January 2021 (has links) Dr. Eleine Mad är Madeleine Jacobsssons talesperson för dom vetenskapliga och paranormala upptäckter som uppstår i hennes världar. Hon beskriver innehåll, teknik och estetik utifrån ett kategoriseringssytem där konsten delas upp som olika typer av komponenter och därefter avkodas dessa allteftersom. För att förstå intuitionens inblandning i arbetsprocessen omförvandlas den till tre separata roller av en Sökare, Samlare och Myntare. Med rollerna försöker jag beskriva på vilka sätt som intuitionen är till gagn eller av förödelse för det konstnärliga arbetet. Sagan om M handlar om en grodlik karaktär, Delop, som lämnar sin hemplanet för att uppsöka andra världar. I sitt sökande hittar Delop ett folkslag vars syn och levnadssätt skiljer sig från hennes erfarenheter av “verkligheten” såsom hon lärt sig att överleva i den. / Dr. Eleine Mad is Madeleine Jacobsson's spokesperson for the scientific and paranormal discoveries that arise in her worlds. She describes content, tecniques and aesthetics based on a categorization system where art is divided into different types of components and then decoded as they go. To understand the intuition's involvement in the work process, it is transformed into three separate roles by a Seeker, Collector and a Myntare(In swedish language the one who is a "myntare" -is verbally declaring a concept or term). With these roles I try to describe in what ways intuition is beneficial or devastating to the artistic work. The story of M is about a frog-like character, Delop, who leaves the home planet to seek out other worlds. In her search, Delop finds a world whose views and lifestyles differ from her experiences of "reality" as she learned to survive in it. / <p>Recorded sound and image material of the presentation is available for private use.</p> mjjgkjacb longing desire pang aj worlds shark genital symbol female sexuality worlds content the tale of M Doctor M mad life artifact animals figures emotional states red existentialism epicenter dog mythology folk beer whistle closeness aversions seeker collector myntare stagnation hibernation intuition sausage soup majdalakdemlsmikopa Delop Cow Lice snake hare sheep ödel oktor threat antipathy empathy fear performance function allow belief clitoral heroes monsters pink components situation dual nature euphoria bic-pens reality violence desert sea AQB brain holistics social codes self fairy tale space blue horse hell gotland dizzying flourish anthropomorphic jewels death plaster spiders commit survive frog whale bear purpose communication wild fascination animal incomparable monster ugly disturbed perspective marauder green symbolism who suffer anger reverence gods recast transformation yellow pry entrance interest alternative insignificant rigid position of power as disease real added disgusting wake up doubt mourn pray images horror plants rock stop mjjgkjacb längtan åtrå pang aj världar haj världsallt könssymbol kvinnlig sexualitet världarnas innehåll sagan om M Doktor M mad livet artefakt djur figurer känslomässiga tillstånd röd existentialism epicentrum hund mytologi folköl vissla närhet aversioner sökare samlare myntare stagnation dvala intuition korvsoppa majdalakdemlsmikopa Delop Ko Löss orm hare får Ödel Oktor hot antipati empati rädsla föreställning funktion tillåta tro klitorala hjältar monster rosa världar komponenter situation dubbla natur eufori bic-pennor verkligheten våld öken hav A.Q.B hjärna holistisk sociala koder självet sagorymd blå häst helvete Gotland vimmelkantig florera antropomorf juveler döden plåsterspindlar vägvisare begå överleva groda val björn syfte kommunicering vild fascination djurisk makalös vidunder ful störd perspektiv marodör grön symbolism vem genomlida ilska vördnad gudar omstöpt sammandrabbningar transformation gul bända ingång intresserar alternativ oväsentlig stel maktposition som sjukdom verkligt tillsatt äcklig vakna tvivla sörja be urbilder skräck växter rock stopp Arts Konst
