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

Acta 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 ...

Straw harvesting equipment for combine harvesters in dry land harvesting

IOP Conference Series: Earth and Environmental Science, 2023
Abstract Currently, in Uzbekistan, wheat and barley grown in dry lands are harvested with a combine harvester, and the straw is piled on the ground. However, due to their low yield (12-16 t/ha) in dry lands, straw is not suitable. As a result, most of the straw, especially the small ones, remains on the ground when it is collected with ...

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

Modelling
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

Agriculture
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

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Optimal harvesting patterns for a seaweed harvester [PDF]

IET Irish Signals and Systems Conference (ISSC 2009), 2009
In this paper, a 9 degree of freedom seaweed harvester dynamical model is presented. The model presented describes the coupled dynamics of a vessel and a harvesting device, lifted by a winch, subject to sea waves disturbances. In order to find an appropriate harvesting path, which minimizes the harvester motions, the model response is simulated for ...

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

FEBS 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 ...
