The status and drivers of soil-available nutrients in plant-recovered soils are not fully understood, limiting our ability to explore the role soil geochemical cycling ecosystem sustainability. Here, we combined spatial distribution chemical aggregate properties from six types (subalpine meadow soil, dark brown yellow-brown cinnamon soil) three horizons (a leaching horizon, sediment parent mate...

The stability of the soil aggregates is an important quality indicator, as it affects soil’s overall functionality. As are highly affected by agricultural practices, essential to know how crops interact with aggregation process. Therefore, for obtaining more knowledge, this research was conducted in Estonia organic crop rotation field experiment from 2012/2013 through 2015/2016 study effects (p...

The replacement of natural aggregates by recycled aggregates in the concrete manufacturing has been spreading worldwide as a recycling method to counteract the large amount of construction and demolition waste. Although legislation in this field is still not well developed, many investigations demonstrate the possibilities of success of this trend given that concrete with satisfactory mechanica...

Biodegradable poly(l-lactic acid) (PLLA) and PLLA/CoFe2O4 magnetic microspheres with average sizes ranging between 0.16-3.9μm and 0.8-2.2μm, respectively, were obtained by an oil-in-water emulsion method using poly(vinyl alcohol) (PVA) solution as the emulsifier agent. The separation of the microspheres in different size ranges was then performed by centrifugation and the colloidal stability as...

The formation of methyl-terminated carboxylic acid self-assembled monolayers (SAMs) with even numbers of carbons, from eighteen to thirty, was investigated on the oxide surface of Ti-6Al-4V and component metal oxides. Modified surfaces were characterized using diffuse reflectance infrared Fourier transform spectroscopy (DRIFT), matrix assisted laser desorption ionization-time of flight mass spe...

The study of water in minerals with infrared spectroscopy is reviewed with emphasis on natural and synthetic quartz. Water can be recognized in minerals as fluid inclusions and as isolated molecules and can be distinguished from hydroxide ion. The distinction between very small inclusions and aggregates of structurally bound molecules is difficult. New studies of synthetic quartz using near-inf...

OBJECTIVE Aggregate formation on collagen at arteriolar rates of shear is mediated by coordinated signaling between tyrosine kinase-linked and G protein-coupled receptors. We have investigated the role of these receptors and the actin cytoskeleton in maintaining aggregate stability under shear. METHODS AND RESULTS Platelet aggregates are rapidly formed when blood is flowed over collagen at 10...
