Land, tid & rättvisa / Din Teg av Jorden - A Theory of Land and Time

Cyon, Nikolaj January 2014 (has links)
Verket består av en text. Fokus är på frågeställningen om hur mycket land vi har per person och vad pengar är, samt hur land och pengar ger makt. Texten lägger fram fakta samt undersöker land och pengar ur olika synvinklar. Texten framlägger tesen att statistik kring genomsnittlig mängd land per person är en meningsfull måttstock samt att konstnärer kan göra en bättre valuta en dagens dominerande valutor i världen. / [I examensarbetet ingår utställningen "Din Teg av Jorden - A Theory of Land and Time":] Guerilla garden grown vegetables being offered for time money, six square meters (6 m²) of tomatoes - your share of the global tomato harvest (/global area used for growing  tomatoes) and facts & visualizations of other agricultural statistics (and info about the other almost 2 000 m² used for growing your food/info about the other 1 990 m² of your share of arable land) :Documentation from a drone of a performance where I (Nikolaj/the artist/ingeting?) measured up 21 275 m² of land – your share of land you would get if we divided the land surface of the planet in seven billion equal parts – with tape in the form of a triangle in Botkyrka a Suburb to Stockholm during the Subtopia art ferstival there.  Squlpture (/installation) of all the different biomes (/climate types/zones)of the planet that make up your share of land, each land strip is shaped like the ones that divided the farms in the medeval open field system in most part of Europe, a very fair but ultimately inefficient system that guarantied that everyone got a slive of the best land, the second best land and so on. The land strips form a 1:200 scale form of 2/3 of Kastelholmen a island just next to the school for size comparsion. Material: Mixed media Teknik: Många

Copolymères greffés porteurs d'OLA optiquement purs : De la synthèse aux propriétés de stéréocomplexation pour générer des films multicouches / Grafted copolymers based optically pure OLA : From synthesis to stereocomplexation properties to generate multilayers films

Bahloul, Mohamed 16 July 2015 (has links)
Ce travail est consacré à l’exploitation de la stéréocomplexation issue du mélange d’oligolactate de chiralité opposée (OLLA et ODLA) afin de construire des films multicouches à travers la technique de dépôt en couche par couche (LbL). Dans la littérature, cette interaction basée sur un phénomène de co-cristallisation, a été utilisée pour préparer des assemblages supramoléculaires (micelles, gels) en milieu solvant, à travers notamment la synthèse de copolymères greffés ou séquencés contenant des segments d’OLA. Dans ce contexte, des copolymères greffés constitués de chaîne principale hydrophile (guar ou alcool polyvinylique (PVOH)) porteur de segments d’OLA optiquement purs et de chiralité opposée (guar-g-OLA ou PVOH-g-OLA) ont été synthétisés. Ces dérivés ont été obtenus par un couplage de type « Grafting onto » basé sur une réaction d’estérification entre i) le polymère hydrophile et ii) des oligolactates L ou D, de masse contrôlée et porteurs de fonctions acide carboxylique en extrémité. Dans le cas des copolymères à base de guar, la synthèse s’est avérée laborieuse et n’a permis que d’obtenir des copolymères dont le pourcentage massique en OLA varie de 2 à 18 %. Concernant les copolymères à base de PVOH et à travers la variation des paramètres expérimentaux, des copolymères optiquement purs présentant des degrés de substitution (DS) en OLA variés (de 2 à 8 %), soit un pourcentage massique en OLA variant de 40 à 80 %, ont été obtenus. L’aptitude de ces derniers copolymères énantiomère à stéréocomplexer en masse et milieu solvant (DMSO) a été étudiée en détail par des techniques expérimentales complémentaires telles que la DSC, la DRX, la RMN 1H et la FTIR. Il s’avère que le greffage covalent des OLA sur la chaîne de PVOH ne limite en rien la stéréocomplexation. De plus, en milieu solvant, la cinétique de stéréocomplexation s’avère très rapide, ce qui est un pré-requis essentiel pour élaborer des films multicouches par la technique dite du LbL. Des analyses en AFM, de mouillabilité et de spectroscopie FTIR en mode ATR ont montré la faisabilité de construire des films multicouches LbL par stéréocomplexation. De plus, l’influence du degré de substitution de ces copolymères ainsi que l’impact du procédé de dépôt (« dip-coating » versus « spin-coating » de solutions de copolymères énantiomère seuls, ou de solutions de complexes préalablement formés) ont été étudiés. / This work is devoted to the exploitation of the mixture of stéréocomplexation oligolactate of opposite chirality (OLLA and ODLA) to construct multilayer films through deposition technique layer by layer (LbL). In the literature, this interaction based on the phenomenon of co-crystallization, was used to prepare supramolecular assemblies (micelles, gels) in a solvent medium, in particular through the synthesis of graft or block copolymers containing segments OLA. In this context, graft copolymers of hydrophilic main chain (guar or polyvinyl alcohol (PVOH)) bearing optically pure OLA segments of opposite chirality (guar-g-OLA or PVOH-g-OLA) were synthesized. These derivatives were obtained by a coupling type "grafting onto" based on an esterification reaction between i) the hydrophilic polymer and ii) oligolactates L- or D- with controlled mass and bearing carboxylic acid functions in end. In the case of guar-based copolymers, the synthesis has proved laborious and has allowed to obtain copolymers which the percentage by mass OLA varies from 2 to 18%. Regarding copolymers based PVOH and through the variation of experimental parameters, optically pure copolymers having different degrees of substitution (DS) of OLA (2 to 8%), a percentage by mass OLA ranging from 40 to 80 %, were obtained. The ability of these latter copolymers enantiomer to stereocomplexation in mass and in solvents (DMSO) was studied in detail by complementary experimental techniques such as DSC, XRD, 1 H NMR and FTIR. It turns out that the covalent grafting of OLA on the PVOH chain does not limit the stéréocomplexation. Moreover, in a solvent medium, the stéréocomplexation kinetics is very fast, which is an essential prerequisite for the development of multilayer films by the LbL technique called. Analyzes AFM, wettability and FTIR spectroscopy in ATR mode showed the feasibility of building LbL multilayer films by stéréocomplexation. In addition, the influence of degree of substitution of these copolymers as well as the impact of the deposition process ("dip coating" versus "spin coating" of copolymer solutions enantiomer alone, or complex solutions previously formed) have been studied.

Abstract This paper is about the philosophies created by Henry David Thoreau (1817-1862) and Friedrich Nietzsche (1844-1900). The purpose is to show the high degree of similarities between Thoreau’s and Nietzsche’s philosphy. At first glance, it seems far-fetched to suggest an affinity between them; the differences in style and choice of subjects, have most certainly contributed to the fact that very few comparisons so far have been made. There is no evidence that one experienced any influence over the other, neither writer seems to have been aware of the other. Also their different areas of use during the 20th century, may have influenced the almost total lack of search for affinity. Thoreau’s philosphy has often been used by environmentalist movements, while Nietzsche has been connected to a wide range of various strivings, such as totalitarian regimes, individualistic artists and post-modern thinkers. But if one disregard these facts, look beyond the differences, and break down their texts in search for their most fundamental opinions, one will see that Nietzsche and Thoreau shared a number of concerns. They were both ciritical to many aspects of the modern civilisation, espacially the way of life it encouraged. It was a life style, deep rooted in an obstructive tradition, that did not take the very essential conditions of life into consideration. This was both Thoreau’s and Nietzsche’s opinion, and their philosophies represent a willingness to re-establish a way of life that ignores all traditions hostile to life. Both of them criticize the religion and its moral of work, the modern science, and many institutions of the modern society – the schools and the prisons for example. But they also praise things, things they claim to have a value in contrast to the modern way of life – the simple things.

All these simple things contribute to Thoreau’s and Nietzsche’s opinion of life; it should be looked upon with the eyes of a child. Life should be like a play.

Den gröna korridoren : Biologisk mångfald i stadsrummet

Härnborg, Rebecka January 2021 (has links)
Mitt mål är att göra stadsrummet inbjudande för fler än bara människor och stärka ekosystemet där fjärilar är en viktig del, både som pollinerare och föda för andra arter. Jag har valt att hjälpa just fjärilar då deras antal under de senaste åren har halverats och är i starkt behov av stöttning.  Med design som verktyg kommer jag att introducera de värdväxter som fjärilen är beroende av för att överleva. För att skapa en så stor förändring som möjligt använder jag mig av ett objekt som redan har en stark närvaro i stadslandskapet nämligen lyktstolpen.   Jag har designat en växtbädd som är anpassad efter lyktstolpen och i den finns det möjlighet att plantera upp till 24 st växter. Tack vare lyktstolparnas strategisk placering kan man med hjälp av min design koppla ihop stadens grönområden och introducera växtlighet där det i dagsläget inte finns någon. Hade inte du velat bo i en stad med massa växter och vackra fjärilar?
