In the cloud computing service model, users consume computation resources provided through the Internet, often without any awareness of the cloud service provider that owns and operates the supporting hardware infrastructure. This marks an important change compared to earlier models of computation, for example when such supporting hardware infrastructure was under the control of the user. Given th

In the present study, we applied a regularized inversion method to extract the particle size, magnetic moment and relaxation-time distribution of magnetic nanoparticles from small-angle x-ray scattering (SAXS), DC magnetization (DCM) and AC susceptibility (ACS) measurements. For the measurements the particles were colloidally dispersed in water. At first approximation the particles could be assume

We present a detailed study of open heavy flavor production in high-energy pp collisions at the LHC in the color dipole framework. The transverse momentum distributions of produced b-jets, accounting for the jet energy loss, as well as produced open charm D and bottom B mesons in distinct rapidity intervals relevant for LHC measurements are computed. The dipole model results for the differential b

Stair ascending performance is critical during evacuation from buildings and underground infrastructures. Healthy subjects performed self-paced ascent in three settings: 13 floor building, 31 floor building, 33 m stationary subway escalator. To investigate leg muscle and cardiorespiratory capacities and how they constrain performance, oxygen uptake (VO2), heart rate (HR) and ascending speed were m

This paper describes the properties and performance status of vertical III-V nanowire transistors. The development of key process modules has advanced the vertical fabrication technology and competitive device performance is reported for InAs MOSFETs and TunnelFETs. Besides the benefits in electrostatic control and the ease in integration on Si substrates, the vertical transistors offers a path to

Markstörningar, som stubbskörd och markberedning, leder initialt till minskad koldioxidavgång från marken, visar en serie nya försök. Det är tvärtemot vad man tidigare har antagit. Efter det första året ligger avgången på ungefär samma nivå för störd mark som för ostörd.

Over the last several decades, γ-aminobutyric acid (GABA) has attracted much attention due to its diverse physiological implications in plants, animals, and microorganisms. GABA naturally occurs in plant materials and its concentrations may vary considerably, from traces up to μmol/g (dry basis) depending on plant matrix, germination stage, and processing conditions, among other factors. However,

Departing from previous research on digital action networks, this paper approaches the spread and emotional contagion of digital activism slightly differently, looking for it not necessarily inside the social movement itself, but rather outside it. By questioning the implicit assumption that the spread and emotional contagion of digital activism is contained only in the context of social movements

I fyra försök var utsläppen av de kraftfulla växthusgaserna lustgas och metan ungefär på samma nivå från stubbskördade ytor som från ytor där stubbarna var kvar. Inte heller markberedning gav några signifikanta effekter. De här studierna är de första i världen på det här området, och resultaten måste därför tolkas med viss försiktighet.

We argue that strategic management in general—and capability theory in particular—suffers from problems of infinite regress that can be traced to an unsatisfactory specification of initial conditions. We argue, first, that this has led to an overemphasis on path dependence, experience, and history, without sufficient attention on initial conditions: more proximate, decision-oriented punctuation po

The early Cambrian succession at Chengjiang contains the most diverse Cambrian fossil assemblage yet described, and contributes significantly to our understanding of the diversification of metazoans in the Cambrian “explosion”. The Cambrian Period occupies a transitional episode of global ocean chemistry, following the oxygenation of the surface ocean and of shallow marine environments during the

Soil disturbance from stump extraction and site preparation will initially lead to a reduction in carbon dioxide emissions from the soil. This is one result achieved from a series of new experiments established throughout Sweden and is contrasting to what was previously assumed. After one year however, this initial reduction had disappeared and emissions were around the same level for bothdisturbe

Increasing popularity and applications of the anaerobic digestion (AD) process has necessitated the development and identification of tools for obtaining reliable indicators of organic matter degradation rate and hence evaluate the process efficiency especially in full-scale, commercial biogas plants. In this study, four biogas plants (A1, A2, B and C) based on different feedstock, process configu

The emissions of the greenhouse gases methane and nitrous oxide wereconsistently low in relation to carbon dioxide emissions at four experimental sites.Stump harvesting did not seem to affect the emissions of methane and nitrousoxide. Soil moisture was a major factor for methane emissions – independent ofsoil treatments. These studies are the first ones in the world and should beinterpreted with c

Surface display couples genotype with a surface exposed phenotype and thereby allows screening of gene-encoded protein libraries for desired characteristics. Of the various display systems available, phage display is by far the most popular, mainly thanks to its ability to harbour large size libraries. Here, we describe the first use of a Gram-positive bacterial host for display of a library of hu

Background: Apolipoprotein A-I (apoA-I) in high-density lipoprotein (HDL) is a key protein for the transport of cholesterol from the vascular wall to the liver. The formation and structure of nascent HDL, composed of apoA-I and phospholipids, is critical to this process. Methods: The HDL was assembled in vitro from apoA-I, cholesterol and 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC) at

Resorting more and more to e-learning means a thorough transformation of the teaching processes. Once the teacher-student communication is realized on yahoo-groups or Facebook-groups, the classical roles in the classroom become obsolete. With teachers having the possibility to enter in due time on students’ forums, the former relation of power in education moves to a collaborative one. More and mo

The active membership of Swedish trade unions and union confederations is recorded year for year (women union members in a separate column). The organizational history of the individual trade unions and confederations is also shown.
