Preferential flow paths have been widely characterized by many visualization methods. However, the differences in preferential under various land uses and their relationships to hydraulic properties remain uncertain. The objectives of this study are (1) characterize (forest orchard) combining drainage dye-staining methods (2) build a connection between hydraulic-related parameters extract propo...

An Ultic Haploxeralf soil collected from ridges built into the slopes of the Coastal Mountain Range of Central Chile was used in applications of humic and fulvic acids (HFA) extracted from sludge from sewage treatment plants, in combination with gypsum (CaSO4). A total of 12 treatments were applied by combining four doses of HFA (0, 20, 30 and 40 t ha-1) with three doses of gypsum (0, 1.2 and 6...

We have developed a biodegradable composite scaffold for bone tissue engineering applications with a pore size and interconnecting macroporosity similar to those of human trabecular bone. The scaffold is fabricated by a process of particle leaching and phase inversion from poly(lactideco-glycolide) (PLGA) and two calcium phosphate (CaP) phases both of which are resorbable by osteoclasts; the fi...

Abstract We use the known surface boulder-size distribution of C-type rubble pile asteroid Ryugu (NEA 162173) to determine its macroporosity, assuming it is a homogeneous granular aggregate. show that volume-frequency boulders, cobbles, and pebbles, well-represented by lognormal function with σ = 2.4 ± 0.1 μ 0.2 0.05. Application linear-mixture packing theory yields value for macroporosity ϕ 0....

Peatland functions (e.g., carbon sequestration and flora diversity) are largely driven by soil moisture dynamics thus dependent on interactions between hydrologic regimes organic properties. Understanding these is particularly important in drained peatlands, where drier conditions may alter properties with feedbacks to water retention associated ecosystem functions. In this work, we focused the...

Abstract Despite the increasing interest in applying composts as soil amendments worldwide, there is a lack of knowledge on short-term effects compost structural and hydraulic properties. Our goal was to study effect vermicompost-based structure, water retention characteristics, aggregate stability plant use efficiency compared that mineral fertilizers food-waste digestate examine if these are ...

Polyhydroxybutyrate-chitosan-hydroxyapatite (PHB-CHT-HAP) composite scaffolds were prepared by the precipitation of biopolymer-nanohydroxyapatite suspensions and following lyophilisation. The propylene carbonate and acetic acid were used as the polyhydroxybutyrate and chitosan solvents, respectively. The high porous microstructure was observed in composites and the macroporosity of scaffolds (p...
