Concerns about climate change, diminishing social acceptance of traditional fuels, and technological innovations have led several countries to pursue energy transition strategies, typically by massive diffusion of renewable electricity supplies. The German ‘Energiewende’ has been successful so far in terms of deploying renewable power, mainly by applying particular feed-in tariffs, and by bundling

There are many challenges associated with the construction processes of planning and scheduling. These challenges are relevant to all project parties or stakeholders and therefore management roles or organisational behaviours of those parties have to be properly considered and assessed. With this in mind, this study is aimed at assessing practitioners' perspectives on the current significance and

In this study we compare autumn migration strategies in two subspecies of the Common Ringed Plover Charadrius hiaticula in the southern Baltic Sea. This species exhibits a leap-frog migration pattern, whereby northerly breeding populations (C. h. tundrae; henceforth tundrae) migrate past the whole range of the southern population (C. h. hiaticula; henceforth hiaticula). Hiaticula migrates the shor

Superantigens are known to activate a large number of T cells. The SAg is presented by MHC class II on the APC and its classical feature is that it recognizes the variable region of the β-chain of the TCR. In this article, we report, by direct binding studies, that staphylococcal enterotoxin (SE) H (SEH), a bacterial SAg secreted by Staphylococcus aureus, instead recognizes the variable α-chain (T

In an emergency or disaster situation, it is likely that a conglomerate of societal resources will respond to various needs. In such a multi-organizational setting, collaboration becomes necessary. Empirical findings suggest that collaboration can be very problematical and this paper argues that a possible explanation can be found in intra-organizational leadership ideals, dysfunctional in a colla

The observation of heavy-ion-like behaviour in pp collisions at the LHC suggests that more physics mechanisms are at play than traditionally assumed. The introduction e.g. of quark-gluon plasma or colour rope formation can describe several of the observations, but as of yet there is no established paradigm. In this article we study a few possible modifications to the Pythia event generator, which

At night, our visual capacities are severely reduced, with a complete loss in our ability to see colour and a dramatic loss in our ability to see fine spatial and temporal details. This is not the case for many nocturnal animals, notably insects. Our recent work, particularly on fast-flying moths and bees and on ball-rolling dung beetles, has shown that nocturnal animals are able to distinguish co

Solid-state and diffusion NMR spectroscopy are versatile tools that allow for studies of both structure and dynamics of complex solid and semisolid materials. We have developed a suit of pulse sequences based on polarization transfer that is readily applied to studies of formulations and their interactions with biological systems. In the present paper, we illustrate its applicability by using an i

Aim: It is well known that nutritional intervention has positive effects on the secondary prevention of coronary heart disease. Different fat compositions of meals may alter postprandial plasma lipid patterns, which can further influence lipid metabolism in vivo. Methods: In the present study, we investigated postprandial plasma lipid parameters in twenty healthy volunteers after eating fat meals

Background: Biodiesel is the main liquid biofuel in the EU and is currently mainly produced from vegetable oils. Alternative feedstocks are lignocellulosic materials, which provide several benefits compared with many existing feedstocks. This study examined a technical process and its mass and energy balances to gain a systems perspective of combined biodiesel (FAME) and biogas production from str

Background: Pulse wave velocity (PWV) is a biomarker for arterial stiffness, clinically assessed by applanation tonometry (AT). Increased use of phase-contrast cardiac magnetic resonance (CMR) imaging allows for PWV assessment with minor routine protocol additions. The aims were to investigate the acquired temporal resolution needed for accurate and precise measurements of CMR-PWV, and develop a t

A comprehensive experimental investigation relevant to thermal radiation has been performed in a grate-fired test furnace. Thermal radiation is the dominating mode of heat transfer in the grate-fired furnace and yet only a few studies have focused on thermal radiation. No previous works, to the authors' knowledge, have been carried out concerning measurements on radiative heat transfer in grate-fi
