The possibility of reducing the transient times at grade changes in paper production and machine start-ups on the paper machines has highlighted the need for increased knowledge of the steam supply system. Models in this area have been presented in previous work and it is of interest to compare these models with each other and evaluate them against experimental data. This paper reports on the resu

Some systems approaches tend to conceptualize social systems as collective entities, in which emergent properties of the whole can render individuals within a social system invisible. As critical systemic thinkers, however, we choose to see a social system as an emergent property of the interactions between unique individuals whose social relations are of interest. Thus, within the field of critic

Popular Abstract in Swedish 10.SWEDISH SUMMARY(Populärvetenskaplig sammanfattning) Proteiner är viktiga byggstenar i cellen och är uppbyggda av kroppens tjugo olika aminosyror. Varje protein har en unik egenskap och spelar en viktig roll för cellens funktion. Vissa proteiner löser sig i vatten (hydrofila) medan andra är olösliga (hydrofoba). Membranproteiner är hydrofoba proteiner som är inbäddadeMembrane proteins are crucial components of the cell and are involved in many biological processes. Recombinant overexpression systems together with different purification methods are necessary to obtain large amounts of purified receptor for biophysical and functional studies. More knowledge about membrane proteins, and especially G-protein coupled receptors, would facilitate the development of i

Increasing food production is a key step towards attaining food security in Cameroon. For the last half century, increase in production has been achieved by bringing more land under cultivation. In consequence of competition for land between agriculture and other uses that particular route to increasing production to meet the country’s growing demand is now limited. The alternative is to increase Popular Abstract in Swedish Ökad livsmedelsproduktion utgör ett viktigt steg för att uppnå livsmedelssäkerhet i Kamerun. Under det senaste halvseklet har ökningen av produktionen i huvudsak uppnåtts genom ökad uppodling. Till följd av ökad konkurrens om marken från jordbruket och andra sektorer är dessa möjligheter till ökad produktion, för att möta landets växande efterfråga nu begränsad. Alterna

Vehicular networks will not be commercially deployed unless there are applications that benefit from them. Since the first research projects on vehicular networks, see, for example, the PROMETHEUS project [1,2], the main focus has been on increasing traffic safety. With the help of vehicular communication, the number of accidents will decrease and human lives will be saved. Therefore, the two appl

This volume brings together ten papers presented at the 10th International Conference on the Structure of Hungarian (Lund, 2011). The papers cover a broad field of issues in Hungarian relating to phonetics, phonology, semantics, syntax and pragmatics, such as vowel harmony, particle verb constructions, impersonal use of personal pronouns, the diachronic development of comparative subclauses, pseud

Cloud computing has recently received considerable attention, as a promising approach for delivering ICT services by improving the utilisation of data centre resources. On the other hand, the increased usage of ICT, jointly with the increased cost of energy, make designing and managing data centres with energy efficient strategies a crucial and strategical problem. In the literature there are man

To study the development of physical health and some neuromotor functions in anorexia nervosa (AN) 51 individuals (48 females, three males) with a mean AN onset of 14 years, recruited after community screening, were followed prospectively together with 51 age-, sex-, and school-matched individuals without AN (controls). About 10 years after AN onset, all individuals were examined in respect of phy

Saccharomyces cerevisiae produces ethanol efficiently from the hexose sugars in lignocellulose hydrolysates, but it can not utilise pentose sugars such as xylose and arabinose. Stable xylose-utilising S. cerevisiae strains obtained by integration of the Pichia stipitis genes encoding xylose reductase (XR), xylitol dehydrogenase (XDH) and xylulokinase, exhibit low ethanol yields when utilising xylo
