The determination of optimal production capacity for open-pit mines is influenced by various economic and technical factors and is highly susceptible to uncertainties. To effectively address the impact of uncertainty on capacity planning, this study develops a production capacity planning model for open-pit coal mines, based on the theory of economies of scale and incorporating multiple uncertainty constraints. A novel method is proposed to quantify and propagate the uncertainties of key capacity control factors, …

The off-season activity of male moths of cotton pink bollworm was studied at Research Farm, NAU, Surat and five ginneries through installing pheromone traps during January to June 2022 in South Gujarat. The activity of male moths of pink bollworm were observed throughout the year (January to December 2022) at Research Farm and was more pronounced during 1st to 13th Standard Meteorological Weeks (SMW) and 38th to 51st SMW coinciding with the fruiting stages of the crops in the field and less pronounced (<8 male …

This research aimed to evaluate the antioxidant and antimicrobial potential of aqueous extracts derived from Hibiscus rosa-sinensis and Delonix regia flowers, with the objective of exploring their applicability in the formulation of functional food products. The antioxidant capacity of the extracts was assessed using the DPPH radical scavenging assay and the ferric reducing antioxidant power (FRAP) method. The phenolic content of the extracts was quantified using the Folin–Ciocalteu method. Antimicrobial propertie…

The dynamic response law of the vibration cavity effect in the adjacent large-section rectangular coal roadways induced by deep-hole bench blasting vibrations was deeply revealed, and the prediction accuracy of the PPV in the coal roadway was improved. The vibration equations of the coal roadway were derived based on the stress wave propagation theory and the wave-front momentum conservation theorem. Based on coal roadway vibration monitoring data and numerical simulations, the cavity effect and vibration response…

Introduction: Tomato (Solanum lycopersicum L.) is a nutritionally rich vegetable crop of global importance, widely cultivated in tropical and semi-arid regions. In 2022–23, worldwide tomato production reached 20 million metric tonnes from 8.64 million hectares, with Maharashtra contributing 0.67 million metric tonnes from 0.18 million hectares. Problem: Excessive reliance on chemical fertilizers to overcome nutrient deficiencies leads to soil degradation, reduced microbial diversity and environmental concerns. The…
