Peoples' relations to animals and their various roles took many different expressions in the pre-Christian era. In certain contexts animals had practical functions, but others they also had symbolic values. Domsticated animals were a kind of life style metaphors in grave rituals. Wild animals and transformation between humans and animals in pictorial images signified social identity. The archaeolo
Popular Abstract in Swedish BLY I BLOD. ICP-MS-studier av bly i plasma, blod och erythrocyt-proteiner De flesta studier som har gjorts av blys giftighet är grundade på blyhalten i blod, och man vet idag mycket om vilka halter som är förknippade med olika skador. Cirka 99% av blyet i blod finns i de röda blodkropparna, medan plasma vanligen innehåller mindre än 1%. Man har länge trott att anledninAn inductively coupled plasma mass spectrometry (ICP-MS) method for the determination of lead in blood plasma has been developed. The detection limit was below 0.1 microgram/liter, and the precision 5%. There was no significant difference between levels in plasma and serum. Studies of individuals with varying lead exposure showed that in the general population the plasma concentrations were less t
We study agents situated in partially observable environments, who do not have sufficient resources to create conformant plans. Instead, they generate plans which are conditional and partial, execute or simulate them, and learn to evaluate their quality from experience. Our agent employs an incomplete symbolic deduction system based on active logic and situation calculus for reasoning about action
Massive MIMO is considered a key technology for the future wireless communication systems. The promising properties in terms of higher spectral and transmit-energy efficiency are brought by the large number of antennas at the base station (BS). As the number of antennas increases, the aperture of the BS antenna array may become much larger, as compared to today's antenna arrays. In this case, mobi
Det sena 90-talets tre mest populära filmer, ”Jägarna” (1996), ”Fucking Åmål” (1998) och ”Hälsoresan” (1999) skildrade samtliga ett Sverige i ekonomiskt och moraliskt förfall, ett land genomsyrat av "onda" kollektiva mekanismer. Att den populära 90-talsfilmen skildrade vårt land i sådana termer kan rimligen ha att göra med att den ekonomiska tillbakagången i Sverige hade varit drastisk och att mån
Popular Abstract in Swedish I denna avhandling studerades artrikedom, rörelsemönster och utdöenden bland fjärilar och solitära bin. Under senare år har det uppmärksammats att antalet arter av insekter minskar i en alarmerande takt. Fjärilar, bin, blomflugor m.fl. blir allt färre. Eftersom insekterna utgör en stor del av arterna på jorden och dessutom har viktiga funktioner i ekosystemen, som t.ex.During recent decades, concern about the loss of biodiversity has increased. To change this negative trend there is an urgent need for effective conservation measures and there are ample evidence that conservation of organisms without an understanding of their ecology and behaviour is impossible. At the Kullaberg Nature Reserve in the south-western part of Sweden butterflies exhibited a disastrous
Recently two new classes of low-rate codes have been presented. The first class is the super-orthogonal turbo codes (SOTCs) and the second is the maximum free distance (MFD) convolutional codes. In this paper we present an evaluation of the performance vs. arithmetic decoding complexity for these codes and compare them with the previously reported super-orthogonal convolutional codes (SOCCs). For
This study shows how porosity is obtained in a biphasic injectable bone graft when aging it in SBF. The injectable bone consists of apatite and calcium sulphate and the porosity is developed by dissolution of the latter material. It was shown that the dissolution was constant with time. Porosity was formed both on the surface and in the bulk of the material. The maximum compressive strength (29 MP
This study is concerned with a specific rerouting strategy in telecommunication networks named Elastic Robust Rerouting (ERR), introduced first in [8]. We recall main points on this strategy, provide mathematical formulation and discuss in details a solution method. The second question studied in this paper is concerned with its distributed version and some related implementation issues. We report
Popular Abstract in Swedish Under de senaste par decennierna har en specifik tolkning av döva och dövhet blivit alltmer etablerad på det ”officiella” dövområdet i Sverige, tillika anammat av såväl professionella som föräldrar till döva barn. Döva ska enligt detta synsätt hellre betraktas som tillhörande en kulturell och språklig minoritet än som handikappade. Medicinska strävanden att “laga defektIn the last couple of decades a particular interpretation of deaf and deafness has been established in ‘official’ arenas in Sweden. Deaf individuals, according to this view, should not be seen as disabled, but rather as belonging to a cultural and linguistic minority. Such views find expression in a locally established usage that may be termed a deaf culture discourse. Discourse can be seen as a
Anyone who has taught a course in Strategic Management probably provides the same basic content to students including the infamous SWOT (strengths, weaknesses, opportunities and threat) analysis along with the identification of functional level, business level, and generic strategies to enhance an organization’s competitiveness. What might be different in the teaching of strategic management cours
Popular Abstract in Swedish Vid en infektion aktiveras vårt immunförsvar och sätter igång ett inflammatoriskt svar med uppgift att eliminera de främmande mikroberna. Det inflammatoriska svaret är nödvändigt för vår överlevnad och en naturlig del av all läkning. I vissa situationer kan dock inflammationen i sig bli för kraftig och orsaka skada på värdens egen vävnad. Ett dysreglerat eller alltför kLeukocyte recruitment is a rate-limiting step in endotoxemic liver injury. Leukocyte extravasation is a multistep process, supported by multiple combinations of adhesion molecules and chemokine receptors. This thesis examined the mechanisms of activation, adhesion and extravascular infiltration of leukocytes in endotoxin-induced liver injury. It was found that leukocyte adhesion in postsinusoidal
Popular Abstract in Swedish Balansen mellan våra energibehov och den energi som konsumeras är ej längre i jämvikt. Därför är jakten på alternativa energikällor nödvändig. Hållbara energikällor erbjuder ett bra alternativ till fossilbränslen. Bland många typer av hållbara energikällor erbjuder solenergi möjligheten för mer energi än dagens konsumtion. Solceller är de smarta verktyg som omvandlar ljThe balance between our demands of energy and the energy we are consuming is not in equilibrium anymore. Therefore, the search for other energy resources is indispensable. Sustainable energy sources offer the alternative to the fossil fuels. Within many types of sustainable energy sources, solar energy offers more than the total global energy consumption. Solar cells are the smart conversion tools
