Surface complexation of orthophosphate ions at the water-suspended-and-aged gamma-Al2O3/water interface has been studied by means of a series of batch experiments in 0.1 M Na(Cl) medium at 25.0 degrees C in the range 4.8 < -log [H+] < 9.6. The ratio between phosphate concentration and concentration of surface active groups (=AlOH) was varied between 0.15 and 1.50. The suspensions were equilibrated
The Schrodinger equation on a graph together with a set of self-adjoint boundary conditions at the vertices determine a quantum graph. If the graph has one or more infinite edges one can associate a scattering matrix to the quantum graph. It is proved that if such a graph has internal symmetries then the boundary conditions, and hence the self-adjoint operator describing the quantum system, in gen
The failure of many fisheries world-wide, and the concern about marine biodiversity, has sparked a growing interest in the spatial aspects of harvested populations. If a population conforms to the Ideal Free Distribution and that one of the habitats is set aside as a reserve free from harvesting, the design of reserves may be problematic. If a substantial proportion of the unharvested population i
Objective. The redistributive effect of the welfare state is traditionally measured by comparing the gross and net distribution of annual income among adults. This standard approach does not account for the fact that a large share of the taxes paid by adults are paid back to the very same individuals later in life. The objective of this article is to examine the factors that determine the differen
Scolecodonts are common microfossils in Palaeozoic rocks, bearing witness to the extensive radiation of jawed polychacte worms during the Ordovician Period. Information on Ordovician scolecodonts is increasing, though it is still patchy and strongly skewed towards Baltica and Laurentia. Comparison of the faunas of these two palaeocontinents indicates that approximately 50% of the genera, but only
Nanowires are important candidates for use in future electronics, photonics and thermoelectrics applications. We focus here in particular on nanowires for use in thermoelectric power generation and present a method of fabricating dense uniform InAs nanowire arrays amenable to future incorporation of advanced heterostructures that could further increase the thermoelectric performance of these nanow
Research on short- and long-term response to trauma has been expanding over the past twenty years and has found new urgency in recent national and international events. As our understanding of risk factors for who will be most severely affected by trauma expands, what we don't know about the interactions between vulnerabilities and risk factors, peritraumatic and posttraumatic factors, physiologic
We hereby report on a three year project initiative undertaken by our research team encompassing large-scale protein expression profiling and annotations of human primary lung fibroblast cells. An overview is given of proteomic studies of the fibroblast target cell involved in several diseases such as asthma, idiopatic pulmonary disease, and COPD. It has been the objective within our research team
This article deals with the legal understanding of the demands in working life on employees’ability to cooperate. The concept of cooperation ability is here used in the sense of an ability to actively facilitate communication and foster relationships with colleagues and supervisors through flexibility and commitment, and thereby benefit the employer’s business. Special attention is paid to the dis
BACKGROUND People who are religiously unaffiliated (including self-identifying atheists and agnostics, as well as those who say their religion is "nothing in particular") made up 16.4% of the world's population in 2010. Unaffiliated populations have been growing in North America and Europe, leading some to expect that this group will grow as a share of the world's population. However, such forecas
The apparent realities of the communist dystopia lead to specific expectations from the transition to capitalism: the replacement of communism should cause not only a boon in human happiness, but also a resurgence of social life. Two types of observations in the past 20 years challenge these expectations. First, people from former-communist countries are often nostalgic and pessimistic when discus
In mesoscopic and nanoscale systems at low temperatures, charge carriers are typically not in thermal equilibrium with the surrounding lattice. The resulting, non-equilibrium dynamics of electrons has only begun to be explored. Experimentally the time-dependence of the electron temperature (deviating from the lattice temperature) has been investigated in small metallic islands. Motivated by these
While economic issues are not usually much debated in theology, three recent mission documents (The Cape Town Commitment, Together Towards Life and Evangelii Gaudium) have directly addressed them, criticising globalised capitalism more or less sharply and explicitly. However, all three lack transparency in that possible analysis which might provide foundation for the statements made is not visible
The recent discovery of a topological phase transition in IV-VI narrow-gap semiconductors has revitalized the decades-old interest in the bulk band inversion occurring in these materials. Here we systematically study the (001) surface states of Pb1-xSnxSe mixed crystals by means of angle-resolved photoelectron spectroscopy in the parameter space 0 <= x <= 0.37 and 300 K >= T >= 9 K. Using the surf
