Ny förpackning för Renat Brännvin åt Vin & Sprit AB

Älmeby, Anna, Fält, Olle January 2001 (has links)
The purpose of this degree project is to come up with a new package to Renat Brännvin for »Vin & SpritAB« and make the product more attractive on the market of bars, restaurants and hotels. The commissionhas included to decide the material of the package, whether it´s possible to manufacture the productand to make an estimation of the costs.The conditions that »Vin & Sprit AB« set up was to make the product attractive to a younger targetgroup, in this case people from 20 to 40 years old. As Renat Brännvin is considered to be a product of firstclass it´s of great importance that the package reflects the look of a premium product.At first we looked at the history of the company »Vin & Sprit AB« and Renat Brännvin. We decidedthat the package schould consist of a bottle, glasses and a device used when serving the liquor. To getinspiration before sketching we studied different kinds of bottles, glasses and serving devices. We madea lot of different sketches to start with after which we consult with Ingrid Florén – our supervisor from»Vin & Sprit AB« – agreed on one. That one we developed and we made more accurate sketches in 3DStudioMAX.At last we looked at the opportunities to produce the bottle by questioning different manufacturers. Wewanted to know the limitations to consider when making a bottle.

Glas et la question de l'écriture fragmentaire chez Jacques Derrida

Barroso, Henrique January 1991 (has links)
This thesis attempts to analyse both the characteristics and the presuppositions that constitute the writing of the philosopher and literary critic, Jacques Derrida. / More concretely, this analysis proposes to bring out the principal factors that illustrate the form of writing and thought in Glas. Glas is a real laboratory where Derrida plays with the "text" and the broken form of thought. / Derrida proves that the broken form of writing can neither achieve the status of oeuvre nor protect its own literary nature.

Historiska emissioner av bly och arsenik till luft från Åfors Glasbruk och deras konsekvenser för miljön.

Rivas Benavides, Valentina January 2014 (has links)
Åfors glasswork was a company which started in 1876 and closed in 2012 due to the bad economical situation in the company. After its closure, the glasswork left behind contaminated soil with different concentrations of heavy metals such as, arsenic from arsenic trioxide, a chemical used to remove bubbles during the melting of glass, and lead oxide, a chemical used in the production of crystal glass. Crystal glass’s production occurred under 1921-1971, but emissions of lead into the air from Åfors glasswork continued until 2011, because of the artist Bertil Valliens’ artglas was made in Åfors glasswork from 1970’s and onwards. The aim of this study was to estimate how much lead (Pb) and arsenic (As) that were released by Åfors Glasswork into the atmosphere during the operational period of the glasswork in comparison with how much of lead and arsenic were purchased for the company. Added to the assistance of the data from National Archives the variations in the activities of Åfors glasswork could be shown. Finally the study aimed to show the influence of such substances to the environment.  The data that could be collected included information from Åfors glasswork under 1900-1961 and under 1993 -2011. Emission of lead into the air during the period 1900-2011 was about 9 700 kg lead, and the company purchased  approximately 170 000 kg lead oxide under operational period. About the emissions of arsenic to the air during the period 1972-2011 were about 22 kg  of As . Estimations during the period 1900-1971 for arsenic could not be implemented due to lack of information, so probably totals emissions of arsenic could be significantly higher. The knowledge of the amount of metals emitted to the air during all these years helps to present an idea about how polluted the soil, sediment and water around the glasswork may be. It is of most importance to know that lead and arsenic are very stable substances that remain in place for a very long time. This is why those areas must and should be cleaned. / Åfors glasbruk var ett företag som startade 1876 och lades ner 2012 pga. av dålig ekonomi. Efter sin stängning, lämnade bruket efter sig förorenad mark med olika koncentrationer av tungmetaller, bl.a. arsenik från arseniktrioxid som används för att avlägsna blåsor vid smältning och bly från blymönja, en kemikalie som används i tillverkning av kristallglas. Tillverkningen av kristallglas pågick mellan 1921-1971, men Bertil Valliens konstglas gjordes från 1970- talet och därför fortsatte emissionerna av bly till luft från bruket tills 2011. Syftet med studien var att uppskatta hur mycket bly och arsenik som släppts ut från Åfors Glasbruk till luft under driftstiden och beräkna hur mycket bly och arsenik som hamnade i utgående luft jämfört med hur mycket bly och arsenik som köpts in till produktionen. Fakta som kunde samlas in inkluderade information från Åfors glasbruk under åren 1900-1961 samt en del information för åren 1993-2011. Emissioner av bly till luft under perioden 1900-2011 blev ca 9 700 kg bly, och företaget köpte under samma tid ungefär ca 170 000 kg blymönja. Emissioner av arsenik till luft under perioden 1972-2011 blev  ca 22 kg arsenik. Beräkningar för perioden 1900-1971 angående arsenik gick inte att genomföra på grund av databrist så antagligen är de totala emissionerna betydligt större. Att få veta vilken mängd av metaller som släppts ut till luften under alla dessa år hjälper till att skapa en uppfattning om hur förorenad marken, sediment och vatten är i närheten av bruket.
