22+ hour, 33+ min ago   (428+ words) The growing penetration of variable renewable energy (VRE) is increasing the frequency of very low and negative prices, although these events also depend on demand, transmission capacity, price-regime persistence and flexibility resources. This study examines which pre-auction and diagnostic variables…...

23+ hour, 52+ min ago   (432+ words) Ensuring reliable and sustainable energy supply in healthcare facilities is essential due to the critical nature of healthcare services. This study presents a comprehensive techno-economic, environmental, reliability, and operational assessment of biomass-supported hybrid renewable energy systems across five climatically distinct…...

1+ day, 2+ min ago   (558+ words) This study presents an integrated green analytical strategy combining deep eutectic solvent (DES) screening, Fourier transform infrared spectroscopy (FTIR), principal component analysis (PCA), and Box–Behnken response surface optimization for the valorization of pineapple crowns, an underexplored agro-industrial by-product. An…...

1+ day, 53+ min ago   (516+ words) Incremental subsidence induced by sequential longwall panel extraction is associated with panel interaction and progressive instability of the disturbed rock mass. However, the governing mechanisms and the coupled effects of panel and pillar geometries remain insufficiently understood, limiting effective assessment…...

1+ day, 1+ hour ago   (546+ words) Lavandula × intermedia (lavandin) is among the most cultivated Lavandula species, valued for its high essential oil yield and broad applications across different industries. Although it has traditionally been regarded as inferior to true lavender (Lavandula angustifolia), particularly within the field…...

2+ day, 16+ hour ago   (415+ words) Multi-product production systems require effective coordination among production, intermediate storage, downstream processing, and customer demand, particularly under stochastic operating conditions and finite capacity. Unlike existing analytical studies that mainly examine either single-product push–pull systems or multi-product manufacturing systems separately,…...

2+ day, 16+ hour ago   (396+ words) In the field of public service data integration, government agencies are responsible for consolidating data from various industries and establishing big data platforms. Some achievements have been made in this direction, but there are still some issues related to privacy…...

2+ day, 18+ hour ago   (186+ words) This study investigates a sustainable vehicle-routing problem in which a heterogeneous fleet serves geographically dispersed customer demands from a central distribution facility. The problem simultaneously minimizes transportation costs and CO2 emissions, with deliveries performed by either in-house or externally rented vehicles....

3+ day, 19+ hour ago   (719+ words) Pelargonium graveolens and Pelargonium zonale are promising sources of natural antioxidants and other bioactive compounds that may find future use in topical cosmetic preparations. The aim of our study was to investigate the antioxidant properties and chemical composition of extracts…...

3+ day, 19+ hour ago   (449+ words) Precast concrete frame joints in coastal atmospheric environments are susceptible to mechanical performance degradation caused by chloride-induced corrosion, yet joint-scale numerical studies incorporating multi-indicator time-dependent mechanical responses remain limited. This paper presents a coupled framework that integrates chloride diffusion, corrosion,…...
