Application of harvester technologies of timber logging in the process-oriented environment

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2009
Harvester technologies of timber logging currently represent the high spot of technologies used in forestry for timber harvesting and forwarding. A typical feature of the “harvester– forwarder” combination is production rate, which is many times higher ...

Performance Comparison of Hybrid and Standalone Piezoelectric Energy Harvesters Under Vortex-Induced Vibrations

open access: yesModelling
This study investigates the effect of incorporating an electromagnetic harvester inside the bluff body of a 2-DoF hybrid harvester in comparison to a standalone piezoelectric harvester for various external loads. The harvester is excited through a vortex-

Design and Experiment of a Universal Harvesting Platform for Cabbage and Chinese Cabbage

open access: yesAgriculture
To address the issue of the single-crop adaptability of current head-forming leafy vegetable harvesters in China—which limits their ability to harvest multiple vegetable varieties—a universal cabbage–Chinese cabbage harvesting platform was designed. This

To Harvest or Not to Harvest: Mapping and Decision-Making for a Selective Table Grape Harvesting Robot

open access: yesIEEE Robotics and Automation Letters
This letter focuses on robotic harvesting of delicate crops such as table grapes, featuring selective harvesting based on individual product properties. The robot detects grape bunches and estimates their positions and quality attributes. However, sensor limitations and occlusions affect data completeness and accuracy, reducing the cost-effectiveness ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

open access: yesFEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...
