INFLUENCE OF PLANTING FURROWS OPENERS ON AGGREGATES GEOMETRIC MEAN DIAMETER AND SURFACE ROUGHNESS AFTER SOIL TILLAGE BY CHIESELLING

open access: yes, 1995
Uma alta rugosidade superficial e adequado diâmetro médio geométrico (DMG) dos torrões do solo são propri- edades de superfície desejáveis para o controle da erosão hídrica. Por outro lado, ainda é pouco conhecido o efeito da opera- ção de semeadura sobre estas propriedades.

Enhancing Bubble Removal in Geometry‐Optimized Electrodes

open access: yesAdvanced Engineering Materials, EarlyView.
3D‐printed lattice electrodes outperform stochastic foams in alkaline water electrolysis despite 20%–25% lower surface area. Straight flow channels generate Venturi‐like bubble entrainment, suppressing gas accumulation that renders foam interiors electrochemically inactive.

From Shear to Sound: Mechanics–Acoustics Mapping of TPMS Lattices

open access: yesAdvanced Engineering Materials, EarlyView.
Triply periodic minimal surface (TPMS) lattices are mapped across mechanical and acoustic performance, revealing that descriptors validated in compression fail under shear. First‐time comparison with trusses included. A transition from porous to resonance‐driven absorption emerges at 25% density.

Designing Polymer Nanocomposites for X‐Ray Shielding: Mechanisms, Architectures, and Scalable Processing

open access: yesAdvanced Engineering Materials, EarlyView.
This review highlights advances in lightweight, lead‐free polymer nanocomposites for diagnostic X‐ray shielding. By linking filler chemistry, dispersion, architecture, and photon interaction mechanisms, it establishes structure–performance relationships guiding material design.

Comparison of alternative soil particle-size distribution models and their correlation with soil physical attributes

open access: yesJournal of Hydrology and Hydromechanics, 2019
Complete descriptions of the particle-size distribution (PSD) curve should provide more information about various soil properties as opposed to only the textural composition (sand, silt and clay (SSC) fractions). We evaluated the performance of 19 models

Coarse corn particles cause a negative effect on eggshell quality of semi-heavy laying hens

open access: yesAnimal Nutrition, 2019
One of the possible ways to optimize the productive performance of poultry is through the physical processing of ingredients, which can improve the use of nutrients in these animals.

Regression Analysis and Neural Network Model of Working Diameter of Ball-end Mill [PDF]

open access: yes
In ball-end milling, a clear distinction exists between the nominal and the working (or effective) diameters, particularly when machining free-form surfaces.

Influence of Geometric Design on Mechanical Performance of Auxetic Metastructure

open access: yesAdvanced Engineering Materials, EarlyView.
Strategic geometric reinforcement transforms auxetic performance. This study evaluates 3D‐printed arrowhead metastructures, revealing that a modified design with local ring reinforcement suppresses premature failure to achieve superior energy absorption and structural efficiency.
