Multi‐Stimuli‐Responsive Hydrogen‐Bonded Organic Frameworks Nanocarriers Enable Targeted Fungicide Release and Plant Immune Regulation

open access: yesAdvanced Science, EarlyView.
A fluorinated hydrogen‐bonded organic framework nanocarrier (PFC‐1‐F) loaded with PYR and coated with HACC enables multi‐stimuli‐responsive (enzyme/ROS/pH) release at infection sites. Exhibiting targeted antifungal activity against Sclerotium rolfsii, modulating plant antioxidant defense, and demonstrating favorable biosafety across plant, soil, and ...

Soil-structure interaction during pile vibratory driving

open access: yes, 1997
A rational procedure to model the dynamic nonlinear soil structure interaction during pile vibratory driving is presented. The procedure is based on the analysis of the dynamic behavior of a cylinder embedded in a semi-infinite medium.

The Spatiotemporal Genetic Architecture of Seed Vigor in Upland Cotton

open access: yesAdvanced Science, EarlyView.
Leveraging the semi‐automated SeedRanger platform, we profiled the germination kinetics of 356 cotton accessions at a 30‐min interval. This high‐throughput phenomic approach delineated a temporal genetic network comprising 541 stage‐specific loci. Crucially, functional validation identified FLA2 as a pivotal, auxin‐modulated regulator that orchestrates

Mechanical properties of tree roots for soil reinforcement models

open access: yes, 2001
Evidence from forestry has shown that part of the forest floor bearing capacity is delivered by tree roots. The beneficial effect however varies and diminishes with increasing number of vehicle passes. Roots potential for reinforcing the soil is known to

The engineering behaviour of the tropical clay soils of Dhaka, Bangladesh [PDF]

open access: yes, 2001
This research has evaluated the engineering behaviour of the tropical clay soils of Dhaka, Bangladesh. Attempts have been made to show the relationship of mineralogy and fabric with engineering properties.

In Situ Subsoil Stress-Strain Behavior in Relation to Soil Precompression Stress

open access: yes, 2012
Soil compaction negatively influences many important soil functions, including crop growth. Compaction occurs when the applied stress, sigma, overcomes the soil strength.

Effect Of Geometry On Stress In Pile Head Of Rc Sheet Pile Under Vertical Impact Load [PDF]

open access: yes, 2022
Impact driving is one of the driving systems that applies a series of hammer strikes to drive the sheet pile into the earth. There have been instances reported where pile head is damaged due to the action of impact hammer. The pile head failure causes

Natural Variation of COLD and CATECHINS REGULATOR 1 Coordinately Fine‐Tunes Cold Tolerance and Tea Quality in Tea Plants

open access: yesAdvanced Science, EarlyView.
Multi‐trait genome‐wide association mapping identifies a central hub regulator, COLD AND CATECHINS REGULATOR 1 (CCR1), and its excellent natural allele variation, coordinately enhancing cold tolerance and promoting catechins biosyntheis. CsCCR1 interacts with CsCBF1/3 and is transcriptionally activated by CsLUX and CsKUA1 to promote catechins ...

Support characteristics of eco-spiral pile with respect to twisting angle and ratio of borehole diameter to pile width [PDF]

open access: yes, 2017
This study numerically analysed the characteristics of eco-spiral piles (Eco-SPs) as multi-purpose geotechnical supports. The behaviour of eco-spiral piles in the ground was studied with respect to their twisting angle and the ratio of borehole diameter ...
