RÉSUMÉ Les phénomènes d'enfouissement et de fragmentation des charbons de bois des sols de montagne sont mis en évidence par l'analyse anthracologique et par des datations absolues au14C de quatre profils pédologiques provenant des Alpes françaises. Ces dernières s'avèrent indispensables mais insuffisantes pour comprendre le mode de stratification. Les datations doivent être précédées d'une analyse des assemblages anthracologiques à la fois qualitative (composition taxonomique) et quantitative lorsque les sols sont suffisamment riche en charbons.

Abstract:
SnO2 transparent gels have been synthesized from alkoxide precursor in toluene-2-propanol solvents. The chemical reactivity of transition metal alkoxides must be controlled in order to obtain sols and gels. In tin alkoxide based systems, this control can be achieved through complexation by a chelating agent such as acetylacetone. The gelation of the sols has been studied by in situ small-angle X-ray scattering (SAXS) measurements at the European Synchrotron Radiation Facility in Grenoble on the BM02 beamline.

Increasing the fire resistance of wooden building structures is quite effectively ensured thanks to the development of fire-fighting compositions with aromatic components that contribute to the formation of a carbonized layer on the surface of the material during combustion.

The optical spectra of fluorinated yttrium aluminum compositions activated by Eu3+ ions were studied. The compositions were synthesized by thermal decomposition at 800 °C of fluorine-containing complexes of yttrium, europium, and aluminum nitrate, isolated as sols from ethyl acetate (EA). The main phases of the compositions are (Y1-xEux)OF and (Y1-xEux)AlO3.

Abstract:
The aqueous solutions of the amorphous Sb2S3 is not the hydrophobic sols. The amorphous Sb2S3 reacts with H2O and/or H2S (in aqueous solutions); result: – hy-drophilic thioacids, same as the As2O3 reacts with H2O (As2O3 + 3H2O ⇄ 2H3AsO3); this is a reversible reaction. The arsenous acid decomposes to give crystals of the As2O3 (this is a recrystallization process). The solution of the amorphous Sb2S3 in the H2O with H2S give the crystals of the stibnite, and this process can proceed at room conditions. H2CO3 does not decompose this solutions. H2CO3 + insoluble carbonates – this is a buffering

Abstract:
The 2000s were marked by Gh. Ciobanu's persistent interest in the field of music for solo instruments: these are compositions for woodwinds and keyboards. The author explores the reasons for the composer’s increased attention to this area of modern music, as well as the factors that contributed to the concert demand for new works. Annotations to the works reveal the special attention that the composer pays to the study of the possibilities of the musical sound. It is concluded that the compositions for solo instruments were the result of a holistic understanding of this area by the composer, i

Abstract:
Soil microorganisms interact with one another within soil pores and respond to external conditions such as temperature. Data on microbial community composition and potential function are commonly generated in studies of soils. However, these data do not provide direct insight into the drivers of community composition and can be difficult to interpret outside the context of ecological theory. In this study, we explore the effect of abiotic environmental variation on microbial species diversity.

Abstract:
Native and restored plant communities are part of the foundation of park ecosystems and provide a natural context to cultural and historical events in parks throughout the Heartland Inventory and Monitoring Network (HTLN). Vegetation communities across the HTLN are primarily of three types: prairie, woodland, and forest. Park resource managers need an effective plant community monitoring protocol to guide the development and adaptation of management strategies for maintaining and/or restoring composition and structure of prairies, woodland, and forest communities.

Abstract:
Although engineered nanomaterials are active components in a wide variety of commercial products, there is still limited information related to the effects of these nanomaterials once released into the terrestrial environment. A high number of commercial applications use silver nanoparticles (nAg) due to its anti-microbial activity. This may be of concern for waste management since nAg could be applied to soil (e.g., biosolids) or disposed of in traditional landfills, which could lead to possible leaching into surrounding soil. This report aims to provide additional insight into the fate and e
