När man går på bio eller sitter hemma i soffan och ser på film tänker man sällan på filmens egentliga innehåll och symbolik. Man ser på filmen för att slappna av eller för att tänka på något annat. Syftet med denna uppsats är att framförallt analysera de kvinnliga karaktärerna i Lord of the Rings ur ett genusperspektiv och att höja medvetandet om dessa karaktärers roll i filmerna. Framför allt kommer fokus att ligga på de tre kvinnliga gestalterna som skildras. Jag har även valt att kortfattat behandla karaktären Rosa Kattum, som kontrast till de andra kvinnorna då hon skiljer sig från dem på ett för uppsatsens syfte intressant sätt..

This paper presents the results from an osteological method study of the Ringsjöholm fishbone material. Ringsjöholm is located in Scania, southern Sweden and is 14C dated to 5960-5200 B.P. The aim of this paper is to critically analyse methods used on fish bone material in estimations of season. Three different approaches were used to estimate the fishing season at the Ringsjöholm settlement; 1) identified species, 2) size estimations of the pike based on Enghoffs (1994-95) regression formulae of os dentale, and 3) growth rings of the pike vertebrae.The identified species and the size estimations of the pike points to the fishing being active both during spring and summer. Growth rings analysis of the pike vertebrae didn?t give any quantitative results because of fragmentation.

Denna uppsats handlar om hur artisterna Håkan Hellström och Ken Ring konstruerar diskurser kring maskuliniteten i sina musiktexter. Utifrån poststrukturalistiskt influerad teori kring feminism och maskulinitet görs en komparativ närläsning som bildar en tematiskt uppbyggd studie. Utifrån det för artisterna gemensamma temat utanförskap visar studien att utanförskapet hos Ken Ring är relaterat till en känsla av maktlöshet. Denna kompenserar Ken genom att konstruera maskulina diskurser med ett överdrivet anspråk på det som den europeiska kulturen förknippar med maskulinitet och genus. Detta kan kontrasteras mot Håkan Hellström som i sitt utanförskap konstruerar maskulina diskurser där ?omanlighet? och ett kärleks- och sexualitetsbegrepp där ?jaget? blir könsmässigt tvetydligt, står i fokus.

Climate on earth is getting warmer, which effects earth?s energy balance and so forth the ocean and atmospheric circulation.  In many sub-polar regions on the northern hemisphere changes due to warming of the climate can be observed. Some examples that already have been observed are shifts in tree line, towards higher altitudes and latitudes, increased ablation of Swedish glaciers and melting of the permafrost on the Siberian tundra. In Sweden climate change scenarios tell us that it will become warmer and that a higher amount of precipitation in form of rain will be an effect from this. To study climate changes in Sweden, transition zones are useful in order to observe changes in distribution of species and animal populations.

Future emission legislation puts great emphasis on increasing the efficiency of the engine, thereby reducing fuel consumption. The tribological contact between cylinder liner and piston ring is where an great amount of energy is lost due to friction, and by reducing these losses an reduction in fuel consumption can be achieved.The aim of this thesis was to evaluate the tested piston ring coatings against a plasma sprayed cylinder liner and rank these combinations of materials for friction and wear resistance. The coatings that were tested was Cr + Al2O3, (Al,Cr)N, two types of CrN and WC / C.The experimental tests were performed with a so-called pin-plate, where used oil with addition of an acidic mixture of sulfuric and nitric acid to mimic the acidic condensate formed when exhausts recirculate, were added with a continuous flow. The results were then analyzed by weighing, studies by optical microscopy and scanning electron microscopy (SEM) and profile measurements.The results from each material combination were that the plasma coated cylinder liner wears too aggressively in order to yield a ranking of the piston ring coatings based on the parameters of friction and wear resistance. It is therefore proposed that an alternative coating on the cylinder liner should be developed, lacking the large abrasive wear on piston rings and that can withstand the corrosive environment resulting in engines equipped with EGR.

Reed-Solomon koder, som ?r en sorts felkorrigerande kod, har m?nga till?mpningar. Exempelvis anv?nds Reed-Solomon koder vid kommunikation eller n?r information sparas p? en h?rddisk. Koderna ser till att informationen kan ?terf?s ?ven om det skulle uppst? fel, vilket g?rs genom att l?gga till redundans till informationen som ska ?verf?ras eller sparas.

The purpose of this study was to develop two types of prediction models for Scots Pine and Norway Spruce. The first type for calculation of the stump diameter under bark the year the tree reached breast height (Dstubh130). The second type for calculation of the annual difference, e.g. the number of growth years between stump height (0.2 m) and breast height (1.3 meters above ground level). The primary thought with these prediction models is to obtain the breast height age in the trees on basis of the number of annual rings at stump.

Syftet med denna uppsats är att fokusera de queera ögonblicken i J.R.R. Tolkiens trilogi The Lord of the Rings för att visa att det queera finns i kulturen på samma sätt som det icke-queera. När är de två hobbitarna Frodos och Sams relation queer? Vad gör den queer? Hur kan vi förstå denna queerhet i termer av homosocialitet och homoerotik? Uppsatsen är inspirerad av Tiina Rosenbergs queera läsningar, jag använder mig dessutom av Adrienne Richs teori om "lesbisk kontinuitet" och Sedgwicks resonemang om manligt homosocialt begär. Jag har kommit fram till att Frodos och Sams relation rör sig mellan mer och mindre queerhet.

Hägglunds Drives in Mellansel, Sweden, manufacture radial piston hydraulic motors foremostwithin applications in the industry. These motors have several sliding contacts, one of these, isthe contact between piston ring and cylinder bore. The radial piston hydraulic motors advantageis to produce high torque in very low rotation velocity, this result in that the maximum slidingvelocity between piston ring and cylinder bore, during the whole stroke, is very low. Theconsequence of this low sliding velocity is that the contact between piston ring and cylinderbore, during the whole stroke, is bound to the boundary lubrication regime. This result in, thatthe piston ring is exposed to wear, thus affect the service life of the complete hydraulic motor.To minimize wear of piston ring, it is essential to determine the oil film thickness between thepiston ring and cylinder bore.

In my thesis I have sand blasted different type of woods - ring-porous and diffuseporous deciduous tree species and conifers - to show different results depending on the species, the direction of the grain and the effects of surface treatment of a blasted surface.The results of my tests were sometimes unexpected, such as that the sand from blasting almost completely disappeared, that all wood surfaces after blasting exhibited a much lighter or paler surface than before and that the diffuse-porous tree species showed differences in hardness between the beginning and end of annual rings.By creating a library of different kinds of wood and sandblasted surface treatment, I have created a reference bank that I will be able to use me in the manufacturing of interiors, furniture and other objects..

En av Ring P1:s ambitioner är att låta svenska folket få en röst i etern och i den offentliga debatten. Men är det verkligen svenska folkets röst som hörs i Ring P1? Vem är det egentligen som ringer in?.

This study considers Härskarringen (1959?61), a Swedish translation of J. R. R. Tolkien?s The Lord of the Rings (1954?55), within the framework of translation studies and the description of norms within different fields of translation.

BakgrundGenom livet a?r bero?ring betydelsefullt fo?r ma?nniskans va?lbefinnande. Vid bero?ring frisa?tts hormonet oxytocin som bland annat bidrar till sa?nkning av blodtryck och puls. Att fa? bero?ring i vardagen kan vara en sja?lvklarhet fo?r vissa men ju a?ldre en person blir desto fler ma?nniskor i dess na?rhet fo?rsvinner.

Genom att la?sa tidigare forskning om Generation Y, inneha?llsmarknadsfo?ring och om sociala medier under uppsatsprocessen fo?ra?ndrades problemsta?llningen succesivt, i enlighet med en abduktiv forskningsansats. Studiens fokus utvecklades fra?n att underso?ka alternativa marknadsfo?ringsmetoder vid marknadsfo?ring mot Generation Y till att omfatta pa? vilken social medieplattform Generation Y a?r mest mottaglig fo?r inneha?llsbaserad marknadsfo?ring.Syftet med denna studie a?r att hja?lpa fo?retag vars ma?lgrupp a?r Generation Y att rikta sin inneha?llsmarknadsfo?ring i ra?tt kanaler och pa? detta sa?tt spara tid och pengar. Fo?r att uppfylla syftet och besvara studiens problem samlades empirisk data in genom en webbaserad, kvantitativ enka?tunderso?kning som genomfo?rdes av totalt 301 respondenter, alla tillho?rande Generation Y.
