DESIGN AND EXPERIMENTAL STUDY OF SORGHUM CUTTING TABLES BASED ON A PUSH AND DIVISION INTEGRATED OUTER DIVIDER [PDF]

open access: yesEngenharia Agrícola
At present, there are serious problems in sorghum harvesting, such as lodging entanglement and the loss of broken stems due to the lack of an external dividing device for the cutting table and holding device.

Temporal Evaluation of a Minimally Invasive Method of Preimplantation Genetic Testing for Aneuploidy (mi-PGT-A) in Human Embryos

open access: yesReproductive Medicine
Preimplantation genetic testing for aneuploidy (PGT-A) has become a useful approach for embryo selection following IVF and ICSI. However, the biopsy process associated with PGT-A is expensive, prone to errors in embryo ploidy determination, and ...

Straw harvesting equipment for combine harvesters in dry land harvesting

open access: yesIOP 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

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-

An optimized tuned mass damper/harvester device [PDF]

open access: yes, 2014
Much work has been conducted on vibration absorbers, such as tuned mass dampers (TMD), where significant energy is extracted from a structure. Traditionally, this energy is dissipated through the devices as heat.
