Hydrological cycle research requires a detailed analysis of the involved parameters to understand watershed behavior comprehensively. In recent decades, both Geographic Information Systems (GIS) and Digital Elevation Models (DEMs) were implemented and took a substantial role in watershed geomorphological parameterization; however, the variability of these instruments remains a challenge, together with high-resolution DEMs being unavailable, requiring digital processing to improve resolution. This ...

Electrospun (bio)polymeric fibers have attracted widespread interest as functional materials with suitable morphology and properties for their use as tissue engineering scaffolds and/or wound dressings. The fibrous/porous morphology of this type of materials promotes the adhesion and proliferation of tissue cells, but on the other hand, pathogenic microorganisms unfortunately can also be attached to the fibers, thus leading to serious infections and consequently to the immediate removal of the scaffolds ...

The main disadvantage of electrospun mats is the propensity to bacterial adhesion associated with their peculiar nanofibrous morphological features. The aim of this work was to design electrospun poly(d,l-lactide) (PLA)-based nanofibrous mats containing ZnO-graft-PLA nanoparticles with enhanced antibacterial properties by promoting good dispersion of such PLA-modified nanoparticles within PLA nanofibers. A careful analysis of the physical properties associated with the precursory solutions was carried ...

In the Melastomataceae, flowers with superior ovaries usually develop into capsular fruits, while flowers with inferior or partially inferior ovaries develop into berries. The phylogenetic position and affinities of four enigmatic genera with inferior ovaries and capsular fruits, Allomaieta, Alloneuron, Cyphostyla, and Wurdastom, were investigated using three plastid loci (rbcL, ndhF, and rpl16) and morphological characters. These four genera have been placed at times in their own tribe, the Cyphostyleae, ...

The habitat use and the phenology of the large grasshopper Acrostira euphorbiae García and Oromí endemic to La Palma (Canary Islands) are studied. This grasshopper is entirely dependent on the Canarian endemic shrub Euphorbia lamarckii both for food and to avoid predation. Adults stay on subapical branches during the day, probably to reduce the risk of predation, and climb up to the apex at night to feed. While females seem to ensure the genetic diversity of offspring by waiting for visits by different ...

Abstract A series of poly(acrylonitrile‐butadiene‐styrene)/ZnO nanocomposites with different ZnO nanoparticles content were synthesized by a mass‐suspension polymerization process. Nanocomposites obtained through this technique presented high impact resistance despite the presence of agglomerates for high ZnO nanoparticles content so that, these samples were subjected to twin‐screw extrusion. The extrusion led to a dramatic morphological change and increased in impact resistance, higher than 100% ...
