A procedure for determining the minimum bulk density of soils [PDF]

South African Journal of Plant and Soil, 2001
The purpose of this study was to establish a procedure and develop equipment for determining the minimum bulk density of soils. Six soils with silt-plus-clay contents varying between 8 and 41% were selected. The determination consisted of pouring the soil samples into moulds 100 mm high with 106 and 158 mm diameters from three different falling heights,

Effect of Soil Bulk Density on Water Infiltration in Layered Soil

Tikrit Journal of Engineering Sciences, 2023
Abstract: The optimal design of various irrigation systems requires knowledge and a deep understanding of various soil properties. Water infiltration in the soil is among the most prominent of these characteristics. Ten laboratory experiments were conducted to study the effect of the bulk density of stratified soils (two-layered soils), Where sandy ...

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

Advanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

Development of a Simplified Dynamic Testing Device for Turfed Sports Surfaces [PDF]

, 2011
The response of natural turf surfaces to loading changes with the force and loading rate applied. Quantification of surface behaviour to athlete loading is complicated by the lack of devices that replicate forces, stresses and loading rates of ...

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.

Did cover crop or animal manure ameliorate corn residue removal effects on soil mechanical properties after 10 years?

Journal of Agriculture and Food Research, 2023
Crop residue removal may negatively affect soil mechanical properties, which are key components of soil quality. To evaluate potential long-term effects, we assessed the 10-yr impact of corn (Zea mays L.) residue removal (59 % of non-grain biomass ...

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,
