The Van (forest) Gujjars, surviving as forest pastoralists in the central part of the Indian Himalaya, are a people who, due to their nomadic lifestyle, have since colonial rule found themselves at the margin of Indian society. This paper will look at the relationship between the Van Gujjars and their forest base in a historical perspective from colonial rule to 'conservation of nature' and the 'r

Popular Abstract in Swedish Cellulosa är ett av de vanligast förekommande biologiska ämnena på jorden och en mycket viktig råvara. Cellulosa är en polymer, uppbyggd av glukosmolekyler som är bundna till varandra i kedjor. Kedjorna kan bli mycket långa och består ofta av flera tusen glukosmolekyler. Eftersom cellulosakedjor är lineära kan de packa sig parallellt med varandra och bilda styva fibrer Soluble derivatives of cellulose have become increasingly important in industrial products e.g. in pharmaceutical applications and in technical dispersions. The polymer characteristics of modified celluloses are to a high degree determined by the substituent distribution along the polymeric backbone. The distribution will be more or less heterogeneous both due to the fact that polymers from renewa

Popular Abstract in Swedish Proteiner är livsnödvändiga och finns i alla celler. De flesta proteinerna katalysear kemiska reaktioner och kallas då enzymer. Enzymer och proteiner (äggviteämnen) är uppbyggda av aminosyror ihopkopplade till kedjor som kan vara olika långa. Det finns 20 stycken olika aminosyror. Man kan göra en liknelse med ett pärlhalsband tillverkat av 20 olika pärlor, varje pärla m

In this thesis the relation between lung surfactant structure and functional properties have been studied. Experimental results show that the alveolar surface is formed by a coherent surface phase with a structure equal to tubular myelin. The properties of this phase may explain certain unresolved issues in lung physiology, e.g., mechanical stability of surfactant during the breathing cycle, the

Popular Abstract in Swedish Intresset för metallbaserade läkemedel har växt stadigt de senaste årtionden. Kemins utveckling ger oss hela tiden mer förståelse och bättre verktyg för studier av olika metallkomplex och deras biologiska verkning. Utvecklingen och kunskapen har ökat så mycket, att nya specialiserade discipliner har vuxit fram, som till exempel bio-oorganisk och biometallorganisk kemi. Various metal complexes have been used in medicine traditionally, although their use was often connected with mystery and with a lack of empirically (clinically) proven effect. In modern times, the development of biochemistry, bioinorganic and bioorganometallic chemistry allows us more in-depth understanding of biological action of metal containing substances. Among metal-containing drugs used tod

In this report we are presenting two decoding algorithms for binary variable-length codes, based on a look-up table approach. This type of algorithms are familiar to software designers, but the authors have not been able to find any scientific material, where the decoding speed is analysed. The algorithms will decode one or several source symbols for each cycle of the algorithm. The look-up table

Childhood is a period of extensive cortical and neural development. Among other things, axons in the brain gradually become more myelinated, promoting the propagation of electrical sig-nals between different parts of the brain, which in turn may facilitate skill development. Myelin is difficult to assess in vivo, and measurement techniques are only just beginning to make their way into standard im

Bryophytes (mosses, liverworts, and hornworts) have interested researchers because of their high chemical diversity and their potential uses in pharmaceutical, food, and cosmetic industries. Specifically, long-chain polyunsaturated fatty acids (l-PUFA) such as arachidonic acid (AA) and eicosapentaenoic acid (EPA) are commonly found in bryophytes, but not in vascular plants. Bryophytes accumulate P

The Cherenkov Telescope Array (CTA) is the next-generation gamma-ray observatory currently under construction. It will improve over the current generation of imaging atmospheric Cherenkov telescopes (IACTs) by a factor of five to ten in sensitivity and it will be able to observe the whole sky from a combination of two sites: a northern site in La Palma, Spain, and a southern one in Paranal, Chile.

Most parliamentary democracies have seen a rise of populist radical parties during the past decades. Many countries have also experienced severely delayed government formation processes, with caretaker governments in office for extended periods of time. Are these delays related to the rise of radical parties? We argue that the rise of populist radical parties may prolong the bargaining process, du

We report the discovery and characterization of HD 89345b (K2-234b; EPIC 248777106b), a Saturn-sized planet orbiting a slightly evolved star. HD 89345 is a bright star (V = 9.3 mag) observed by the K2 mission with 1 min time sampling. It exhibits solar-like oscillations. We conducted asteroseismology to determine the parameters of the star, finding themass and radius to be 1.12-0.01+0.04 M⊙ and 1.
