Morfogênese e estrutura de azevém anual submetido a três intensidades de pastejo = Morphogenesis and structure of Italian ryegrass submitted to three grazing intensities

Acta Scientiarum: Animal Sciences, 2010
Estudaram-se características morfogênicas e estruturais de azevém (Lolium multiflorum Lam.) sob intensidades de pastejo. O delineamento experimental foi inteiramente casualizado, com quatro repetições (transectas) e três tratamentos constituídos por ...

The Cuttlebone Blueprint for Multifunctional Metamaterials: Design Taxonomy, Functional Decoupling, and Future Horizons

Advanced Functional Materials, EarlyView.
Cuttlebone‐inspired metamaterials exploit a septum‐wall architecture to achieve excellent mechanical and functional properties. This review classifies existing designs into direct biomimetic, honeycomb‐type, and strut‐type architectures, summarizes governing design principles, and presents a decoupled design framework for interpreting multiphysical ...

Self‐Assembling Peptide Hydrogels Support Stromal Vascular Fraction Viability to Promote In Vivo Nerve Regeneration

Advanced Healthcare Materials, EarlyView.
Stromal vascular fraction (SVF) may enhance nerve repair, especially when delivered in a self‐assembling peptide hydrogel (SAPH). In vitro, softer SAPH increased neuronal explant outgrowth and supported greater SVF viability and proliferation. In a rat sciatic defect, SVF in an optimized SAPH produced motor and sensory recovery equivalent to autograft ...

Defoliation patterns on a mixture pasture of forage sorghum and Alexandergrass

Semina: Ciências Agrárias
Detailing the morphogenic characteristics of tropical species that form mixed pastures allows a broader view of plant-animal interactions. The objective of this study was to evaluate the intensity and frequency of defoliation in a mixed pasture of ...

Root growth and crop yield of two varieties of wheat grown under differing irrigation regimes : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science in Plant Science at Massey University [PDF]

, 1974
Root growth and crop yield of Gamenya, a standard height variety, and Karamu, a semi-dwarf, spring wheat were compared under 3 irrigation regimes: daily watering; infrequent (fortnightly) watering; and sub-irrigation, where water was introduced into the ...

Ferritin‐Doped Nanoparticles Triggered Tumor‐Specific Darkening for Enhanced Photothermal Tumor Ablation and Immune Activation

Advanced Healthcare Materials, EarlyView.
Ferritin‐doped hybrid nanoparticles triggered accurate tumor‐specific hemorrhage for enhanced in situ photothermal therapy and evoked anti‐tumor immunity. Notably, HFn/GA‐Fe specifically induced tumor hemorrhage 12 h after intravenous injection, resulting in visible color darkening. Through photoacoustic imaging, tumor vessels could be clearly observed
