Particles, climate change, and health have thought-provoking interactions. Air pollution is one of the largest environmental problems concerning human health. On the other hand, aerosol particles can have a cooling effect on climate and a reduction of those emissions may result in an increased temperature globally, which in turn may have negative health effects. The objective of this work was to i

Network theory can be employed in two ways in archaeology: it can be used to analyse archaeological data, or it can be used to model a historical process for the purpose of simulating the data. This paper focuses on the first approach. In such analyses, similar archaeological contexts are often connected to form a similarity network. Similarity is treated as a proxy for social or causal relationsh

Is the cohomology of the classifying space of a p-compact group, with Noetherian twisted coefficients, a Noetherian module? In this paper we provide, over the ring of p-adic integers, such a generalization to p-compact groups of the Evens-Venkov theorem. We consider the cohomology of a space with coefficients in a module, and we compare Noetherianity over the p-adic integers, in the case when the

Increased anthropogenic pressures on coastal marine ecosystems in the last century are threatening their biodiversity and functioning. Global warming and increases in nutrient loadings are two major stressors affecting these systems. Global warming is expected to increase both atmospheric and water temperatures and increase precipitation and terrestrial runoff, further increasing organic matter an

To explore the possible influence of pre-eclampsia on cognitive outcome in children born very preterm after intrauterine growth restriction (IUGR) and abnormal umbilical artery blood flow.

OBJECTIVE: The aim of this research was to study the discomfort experienced by adolescents when answering questions in a survey about sexuality and sexual abuse and to investigate factors that may determine possible experience of discomfort. The research focused particularly on vulnerable adolescents-sexually abused and sexually inexperienced. METHOD: Adolescents in their final year of high school

Organic enrichment may deeply affect benthic nitrogen (N) cycling in macrophyte meadows, either promoting N loss or its recycling. This depends upon the plasticity of plants and of the associated microbial communities, as those surrounding the rhizosphere. Rates of denitrification, dissolved inorganic N fluxes and N uptake were measured in sediments vegetated by the submerged macrophyte Vallisneri

Polanyi’s concept of the ‘double movement’ is frequently interpreted as the opposition between the problematic and unsustainable dynamics of the market and the benign and normatively desirable reaction against this by ‘society’. This paper questions this dualistic interpretation of the double movement and undertakes a problematization of the Polanyian idea of social and environmental protection. I

Nanoconfined 2LiBH(4)-MgH2 is prepared by direct melt infiltration of bulk 2LiBH(4)-MgH2 into an inert nanoporous resorcinol-formaldehyde carbon aerogel scaffold material. Scanning electron microscopy (SEM) micrographs and energy dispersive X-ray spectroscopy (EDS) mapping reveal homogeneous dispersion of Mg (from MgH2) and B (from LiBH4) inside the carbon aerogel scaffold. Moreover, nanoconfineme

Physical exercise is a cornerstone in the management of many neurodegenerative disorders, such as Parkinson's disease, dementia, and stroke. However, much of its beneficial effects on improving motor functions and cognition as well as decreasing neurodegeneration and neuroinflammation are not yet well understood. The obvious limitations of studying the protective mechanisms behind exercise, for ex

Chemical sensitization is an adverse immunologic response to chemical substances, inducing hypersensitivity in exposed individuals. Identifying chemical sensitizers is of great importance for chemical, pharmaceutical and cosmetic industry, in order to prevent the use of sensitizers in consumer products. Historically, chemical sensitizers have been assessed mainly by in vivo methods, however, recen

We present the first ratio-based image segmentation method that allows imposing curvature regularity of the region boundary. Our approach is a generalization of the ratio framework pioneered by Jermyn and Ishikawa so as to allow penalty functions that take into account the local curvature of the curve. The key idea is to cast the segmentation problem as one of finding cyclic paths of minimal ratio

The effect of various nitrogen (N) sources, including riverine dissolved organic matter (DOM), nitrate, ammonium, and urea, on the growth and physiology of the dinoflagellate Prorocentrum minimum was compared in a batch culture experiment. P. minimum grew equally well in the presence of identical amounts of nitrate, ammonium, and urea. Approximately 18 to 20% of organic N bound to the DOM was bioa

Poly(ethylene-co-vinyl acetate)/organically modified clay nanocomposites were prepared using different clay loadings and by varying the amount of organic modifier. The morphology of the nanocomposites was investigated using small-angle X-ray scattering (SAXS), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). SAXS results displayed intercalation of polymeric chains be

Bortezomib is a highly selective inhibitor of the 26S proteasome and has been approved for clinical use in the treatment of relapsing and refractory multiple myeloma and mantle cell lymphoma. Clinical trials are also underway to assess the role of bortezomib in several other human malignancies, including leukemia. However, the mechanism(s) by which bortezomib acts remain to be fully understood. He

Remote sensing provides spatially and temporally continuous measures of forest reflectance, and vegetation indices calculated from satellite data can be useful for monitoring climate change impacts on forest tree phenology. Monitoring of evergreen coniferous forest is more difficult than monitoring of deciduous forest, as the new buds only account for a small proportion of the green biomass, and t

The objective of this paper was to integrate excavation and post-processing of archaeological and osteological contexts and material to enhance the interpretation of these with specific focus on the taphonomical aspects. A method was designed, Virtual Taphonomy, based on the use and integration of image-based 3D modeling techniques into a 3D GIS platform, and tested on a case study. Merging the 3D

According to the Substituted Judgment Standard a surrogate decision maker ought to make the decision that the incompetent patient would have made, had he or she been competent. This standard has received a fair amount of criticism, but the objections raised are often wide of the mark. In this article we discuss three objections based on empirical research, and explain why these do not give us reas
