This review provides a comprehensive account of what is known presently about Amazonian aerosol particles and concludes by formulating outlook and priorities for further research. The review is organized to follow the life cycle of Amazonian aerosol particles. It begins with a discussion of the primary and secondary sources relevant to the Amazonian particle burden, followed by a presentation of t
Abstract in UndeterminedRejections of infants among non-human primates occasionally occur in the wild as well as in captive settings. Controlled adoptions of orphans and introductions of individuals into new groups are therefore sometimes necessary in captivity. Consequently, behavioral research on integration procedures and on the acceptance of infants by adoptive mothers is much needed. In this
With a centre-of-mass energy of 5.5 TeV per nucleon, Pb–Pb collisions at the LHC are expected to provide a copious yield of heavy quarks. In this paper, an overview of the ALICE perspectives for heavy flavour physics will be presented. The ALICE experiment will detect quarkonia both in the e+e− and in the μ+μ− decay channels. Open heavy flavoured hadrons will be studied in the semileptonic decay c
Many studies have found close relationships between accessibility and various socio-economic indicators. Yet, since accessibility tends to have differentiated effects, both socially and spatially, there is a need for a model which allows for a disaggregated analysis of accessibility. The model should be possible to use in areas where road network data is incomplete. In this paper such an accessibi
Dying is inescapable yet remains a neglected issue in modern health care. The research question in this study was "what is going on in the field of dying today?" What emerged was to eventually present a grounded theory of control of dying focusing specifically on how people react in relation to issues about euthanasia and physician-assisted suicide (PAS).
The J/ψ is considered to be among the most important probes for the deconfined quark–gluon plasma (QGP) created by relativistic heavy-ion collisions. While the J/ψ is thought to dissociate in the QGP by Debye color screening, there are competing effects from cold nuclear matter (CNM), feed-downs from excited charmonia (χc and ψ') and bottom quarks, and regeneration from uncorrelated charm quarks.
Despite recent attempts to relax the phase-noise demands on voltage-controlled oscillators (VCOs) for cellular communications [1], mainstream radios require harmonic VCOs capable of a very low phase noise with moderate power consumption, associated to a large tuning range (TR) and a high insensitivity to interfering signals. Ideally, the TR should be in excess of one octave, since this allows the
Although solitary bees are considered to play key roles in ecosystem functions, surprisingly few studies have explored their population dynamics. We investigated the population dynamics of a rare, declining, solitary bee (Andrena humilis) in a landscape of 80 km 2 in southern Sweden from 2003 to 2011. Only one population was persistent throughout all years studied; most likely this population supp
Black liquor is a side-stream in the production of kraft pulp. The extraction of lignin and hemicelluloses from black liquor would reduce the load on the recovery boiler and give valuable by-products. Lignin was separated from black liquor by membrane filtration, using one ceramic and three polymeric nanofiltration membranes, with molecular weight cut-offs in the range of 200 Da to 1 kDa. Ultrafil
In this paper, a novel multiple representation data structure for dynamic visualisation of 3D city models, called CityTree, is proposed. To create a CityTree, the ground plans of the buildings are generated and simplified. Then, the buildings are divided into clusters by the road network and one CityTree is created for each cluster. The leaf nodes of the CityTree represent the original 3D objects
Post-mortem analyses of brains from patients with Parkinson disease who received fetal mesencephalic transplants show that alpha-synuclein-containing (alpha-syn-containing) Lewy bodies gradually appear in grafted neurons. Here, we explored whether intercellular transfer of alpha-syn from host to graft, followed by seeding of alpha-syn aggregation in recipient neurons, can contribute to this phenom
The challenge how to assist enterprises more effectively within industrial hot spots of the Danube River Basin in order to meet environmental standards while enhancing their competitiveness was addressed by the project Transfer of Environmentally Sound Technology (TEST). New, integrated approaches were developed and found to be effective in fostering organizational learning and helping to ensure i
We characterize the boundedness of the Bergman projection on vector-valued L-2-spaces with operator-valued weights in terms of an appropriate condition of Muckenhoupt-type for the weight. This contrasts with the situation en Hardy spaces, where such characterizations are only possible in the finite-dimensional case. (C) 2011 Elsevier Inc. All rights reserved.
Modelling the formation of super-km-sized planetesimals by gravitational collapse of regions overdense in small particles requires numerical algorithms capable of handling simultaneously hydrodynamics, particle dynamics and particle collisions. While the initial phases of radial contraction are dictated by drag forces and gravity, particle collisions become gradually more significant as filaments
