Article Abstract
This paper proposes an innovative back-rotating flinging method for digging out oilseed beans, which is more suitable for lifting the excavated material, in response to the short service life of the existing digging device caused by the entanglement of the root system with the cutting tool. Through the analysis of the interaction and influence between the rotary tiller and the soil-root complex of the plant, a kinetic model of the soil-root complex of the kudzu rhizome being chopped and thrown was constructed, and the operating mechanism of the reverse rotary tiller for the overall overturning, digging and collision fragmentation of the soil-root complex of the plant root system was clarified. A discrete element model of the soil-enveloped root system of the hyacinth bean plant was constructed in its entirety. The structural parameters of the reverse rotary digging device were optimised using discrete element simulation and field bench tests.

Organometallic catalysis lies at the heart of numerous industrial processes that produce bulk and fine chemicals. The search for transition states and screening for organic ligands are vital in designing highly active organometallic catalysts with efficient reaction kinetics. However, identifying accurate transition states necessitates computationally intensive quantum chemistry calculations.

Rice is consumed by ∼50% of the global population, grown primarily in flooded paddy fields, and is susceptible to arsenic accumulation. Inorganic arsenic, particularly in reduced form (As(III)), is considered the most toxic and is more likely to accumulate in rice grains under flooded systems. We postulate that increased levels of highly reactive iron minerals, such as ferrihydrite, in paddy soils can regulate the bioavailability of arsenic and reduce its uptake by priming iron plaque formation.

The frequency and severity of heat waves are expected to worsen with climate change. Exposure to extreme heat, or prolonged unusually high temperatures, are associated with increased morbidity and mortality. The fetus, infant, and young child are more sensitive to higher temperatures than older children and most adults given that they are rapidly developing.

Background And Aim: Hematological parameters are critical indicators of health and physiological status in goats. This study aimed to evaluate the effects of location, feeding regimen, age, and body condition score (BCS) on hematological parameters in Creole goats reared under extensive systems on the southern coast of Peru and to establish context-specific reference values.
Materials And Methods: A total of 111 multiparous goats from nine herds were assessed.

is the most widely cultivated high-protein forage crop globally. However, its cultivation in high-latitude and cold regions of China is significantly hindered by low-temperature stress, particularly impacting the root system, the primary functional tissue crucial for winter survival. The physiological and molecular mechanisms underlying the root system's adaptation and tolerance to low temperatures remain poorly understood.
