Características morfológicas e produtivas de feijão guandu anão cultivado em solo compactado Morphological and productive characteristics of the dwarf pigeonpea cultivated in compacted soil

Revista Brasileira de Engenharia Agrícola e Ambiental, 2013
Aliado ao uso indiscriminado de maquinários agrícolas, o manejo inadequado altera a densidade natural do solo causando redução em sua qualidade física e, por conseguinte, implicando em efeitos negativos no desenvolvimento de culturas. Assim, objetivou-se

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Multimodal Soft Surgical Robots Enabled by Eco‐Degradable, Sterilizable Polymers and Transient Electronics

Advanced Functional Materials, EarlyView.
A compostable PGS soft surgical robot with interchangeable modules integrates transient Mo tactile and Si thermal sensors for dual feedback. The device preserves its function after clinical‐grade sterilization, demonstrates stable actuation and cardiac tissue grasping with real‐time in vivo pulsatile monitoring, and biodegrades post‐use with soil‐safe,

Compressibilidade de um Argissolo Vermelho fisicamente degradado e recuperado Compressibility of a Acrisol in physically degraded and reclaimed conditions

Revista Brasileira de Engenharia Agrícola e Ambiental, 2010
A reconstituição da qualidade de solos fisicamente degradados tem sido feita por sistemas de manejos conservacionistas; no entanto, a melhoria da estrutura do solo o torna muito suscetível à compactação quando sofre compressões pela mecanização.

Soil reaction to heavily loaded rubber tracks and tyres [PDF]

, 2007
The importance of undercarriage design with respect to its effect on soil density changes grows with the size of harvest machinery. Therefore this study elucidates the mechanics of soil displacement caused by different undercarriage systems of combine ...

Spatially Decoupling Heating and Evaporation for Convection‐Enhanced 3D Solar Evaporation With Continuous Salt Harvesting

Advanced Functional Materials, EarlyView.
An architecture‐enabled bottom‐heated 3D solar convective evaporator spatially decouples photothermal heating from evaporation, triggering natural convection that intensifies sidewall vapour removal and heat transfer. The system achieves significantly enhanced evaporation rates over 2D and conventional 3D designs while confining salt precipitation to ...

THE EFFECT OF SOIL TEXTURE AND DENSITY ON THE NEUTRON AND DENSITY PROBE CALIBRATION FOR SOME TROPICAL SOILS

Soil Science, 1974
THE EFFECT OF SOIL TEXTURE AND BULK DENSITY ON CALIBRATION OF NEUTRON MOISTURE AND DENSITY PROBES WAS INVESTIGATED FOR FIVE TROPICAL FERRALLITIC SOILS. SOIL TEXTURE AND BULK DENSITY WERE FOUND TO HAVE SIGNIFICANT EFFECT ON THE NEUTRON PROBE CALIBRATION.

Bioinspired Mechanically Robust Organic–Inorganic Hybridized Bio‐Adhesives With up to 50% Inorganic Components by Bi‐Continuous Phase Engineering

Advanced Functional Materials, EarlyView.
A robust plant protein adhesive was prepared by fabricating a bi‐continuous organic–inorganic hybrid structure. Compared with traditional organic–inorganic hybrid adhesives, the addition amount of inorganic phase is increased from 0.2%–3.0% to 50%, and the strength and toughness are increased by 6 and 121 times, respectively.
