In Early Scandinavian "under" was used as a preposition with the local meaning 'under', 'below' and possibly also (as in German) 'among', 'between'. During the Middle Ages the preposition also aquired the temporal meaning 'during'. It is discussed whether and how the new meaning can be explained from one of the original local meanings.
The grocery retail industry, with its large product volumes, low margins and fierce competition, is constantly seeking efficiency improvements in its supply chain. The grocery retail industry uses an immense amount of packaging and is directly affected by packaging logistics activities. There is, therefore, a potential for efficiency improvements in the grocery retail supply chain through the inte
Intelligent transport information systems (TIS) are one of the most rapidly emerging applications of wireless vehicular communications using DSRC/WAVE technology. A core function in a TIS is the estimation of traffic density using beacons transmitted by individual vehicles, subsequently used for purposes such as traffic light control or incident detection. In this paper, we conduct an in-depth stu
Popular Abstract in Swedish Vattengråsuggan Asellus aquaticus är ett väldigt vanligt ryggradslöst djur i många typer av svenska vatten. Den kan bli över 10 mm stor och äter allt från dött organiskt material till levande alger och växter. Färgen hos gråsuggan kan variera mycket mellan olika miljöer. Den är oftast mörk men kan även vara nästan vit i underjordiska grottpopulationer. Jag har studerat Pigmentation in the freshwater isopod Asellus aquaticus differed between two habitats. Asellus were lighter pigmented in stands of submerged stonewort vegetation, than in nearby reed stands. Moreover, Asellus pigmentation became lighter with time in recently established stonewort stands. Diet or pigment adjustment had minor influence on pigmentation and mating was random with respect to pigmentati
Here are proposed different studies carried out by the Laboratorio di Archeologia e Storia Ambientale of Genoa University through the use of a geographical historical microanalitical approach to documentary, field and sedimentary sources. The main aim is the reconstruction of different agri-silvo-pastoral practices and of environmental processes connected to the management of mountain resources wi
Yeasts are unicellular fungi exhibiting a huge diversity of life styles and physiologies and their evolutionary span exceeds the one between mammals and unchordates. The recent advances in genome sequencing and comparative genomics accelerated genomic, evolutionary and physiological studies of yeasts, making them a very promising model to study eukaryotic cell, and also deepened our understanding
Popular Abstract in Swedish Komplementsystemet är en grupp proteiner som tillhör det medfödda (icke anpassningsbara) immunförsvaret hos människan. De verksamma komponenterna (ett 15-tal) förekommer i blodet, de flesta i en inaktiv form. Olika delar av komplementsystemet aktiveras av speciella molekylstrukturer, bl.a. strukturer i bakteriers cellväggar (alternativa vägen och MBL-vägen för komplemenThe autoimmune disease Systemic Lupus Erythematosus is associated with hereditary deficieny of early components from the classical pathway of complement activation, but not with deficiency of complement component C3 or of the alternative pathway components. The classical pathway is involved in elimination of pathological immune complexes from the circulation by transport via complement receptor ty
Popular Abstract in Swedish En cell förökar sig genom delning. Före delningen måste den växa och fördubbla cellinnehållet för att det ska finnas material till två nya celler. En cellcykel är de händelser som sker från det en cell delat sig tills den delar sig igen [Fig 1]. En cellcykel kan delas in i fyra faser som cellen måste genomgå innan den är mogen att dela sig. Under första fasen, G1, tillvThe polyamines - putrescine, spermidine and spermine - are polycations found within cells. They have been shown to be essential for optimal cell proliferation and cell survival. Cells maintain their polyamine levels in a well-regulated system involving biosynthesis, catabolism and uptake/excretion. The biosynthetic enzymes - ornithine decarboxylase (ODC) and S-adenosylmethionine decarboxylase (Ado
