Hemicelluloses, which are abundant in nature and have potential use in a wide variety of applications, may make an important contribution in helping relieve society of its dependence on petrochemicals. However, cost-efficient methods for the isolation of hemicelluloses are required. This article presents an economic evaluation of a full-scale process to isolate hemicelluloses from process water fr

New interpretations are given for [ν]Έσσουπῆ ‘watching’, ‘the guard’; Ἀειφὸρ ‘the ever-shallow rapids’; βαρουφόροϛ – βουλνηπράχ ‘the bare rapids; Λεάντι, βερούτζ ‘the violently rushing rapids’. Στρούκουν has a Greek ending and is not a dative plural. Ναστρεζή is a collective formation with a diminutive sense. Both names mean ‘the small rapids’. The reduced vowels are not manifested in these name

This study has determined the fracture mechanical properties of 9 types of rock, namely fine-, medium- and coarse-grained granites, gneiss, quartzite, diabase, gabbro, and fine- and coarse-grained limestones. Test results show among other things that quartzite has the highest compressive strength and fracture energy, while diabase has the highest splitting tensile strength and modulus of elasticit

Popular Abstract in Swedish Syftet med denna studie var att undersöka hur tvångsvård av alkoholmissbrukare upplevs av den som döms till det. Majoriteten av dessa personer är negativa till tvångsvård. I studien har också tagits hänsyn till att resultaten ses utifrån ett bredare perspektiv. Det som också undersökts är alkoholmissbruk generellt, varför klienterna dricker i den utsträckning de gör samThe aim of this study was to investigate how compulsary treatment of alcohol abuse is experienced by persons forced to submit to it, the majority of whom are negative in their attitude toward treatment of this sort. The importance of considering the resluts obtained not in isolation but within a larger context is emphasized. Among the elements of this context examined are alcohol abuse generally,

The nucleus Ge-68 has been studied by gamma-ray spectroscopy following its population at high spin in the reaction Ca-40(S-32,4p) Ge-68. The reaction channel was selected with the Microball array and gamma rays were detected with the Gammasphere array. The level scheme is very complex, reflecting the many different, and presumably mixed, excitation modes in this nucleus. Nevertheless, there appear

Popular Abstract in Swedish ”Luffarturismen” har blivit en populär form av resande. Många svenskar för under en tid - ibland flera månader eller år - en vagabonderande tillvaro på platser långt hemifrån. Resan blir en parentes i vardagen - en extraordinär sfär fylld av förväntningar på äventyret och den äkta upplevelsen. Vad har resenären för bild av det ”Långtbortistan” hon lockas av, och hur skThis dissertation, The Attraction of the Extraordinary - Images and Experiences Among Backpacker Tourists, is a study based on informal interviews with predominantly Swedish independent travellers, as well as observations and documentary analysis of the backpacker subculture. Backpacking is a type of tourism which has been gradually institutionalized. Through the institutionalization of the backpa

Based on spectra from F and G dwarf stars, we present elementalabundance trends in the Galactic thin and thick disks in the metallicityregime -0.8< [Fe/H < +0.4. Our findings can besummarized as follows. 1) Both the thin and the thick disks show smoothand distinct abundance trends that, at sub-solar metallicities, areclearly separated. 2) For the alpha -elements the thick disk showssignatures of c

Flow field-flow fractionation (FFF) has previously been used in successful fractionation and characterisation of the ultra-large wheat protein glutenin. The many parameters, which may influence the retention behaviour, especially when analysing extremely high-molecular-mass samples such as glutenin, are here reported. Size determination from the sample retention time, using FFF theory, will as a r

Scolecodonts, polychaete jaws, generally occur abundantly in Silurian shallow marine successions and are known from all continents except Antarctica. The assemblages are typically characterized by taxa with labidognath, placognath and prionognath type jaw apparatuses. They commonly include species of Kettnerites Zebera, 1935, Oenonites Hinde, 1879, Mochtyella Kielan-Jaworowska, 1961, Protarabellit

An object-oriented extension to canonical attribute grammars is described, permitting attributes to be references to arbitrary nodes in the syntax tree, and attributes to be accessed via the reference attributes. Important practical problems such as name and type analysis for object-oriented languages can be expressed in a concise and modular manner in these grammars, and an optimal evaluation alg

Investigations of variations in metabolic efficiency and thermogenesis have a short and turbulent history. In small animals, non-shivering thermogenesis and diet-induced thermogenesis have a great impact on overall body weight, and the question is whether mechanisms to waste energy have evolved also in human energy metabolism. The candidate molecules for this adaptive thermogenesis are the uncoupl
