This study optimized green extraction of a synergistic tri‐herbal blend of Ginkgo biloba, Astragalus membranaceus, and Salvia miltiorrhiza. The 1:1:2 blend showed the highest TPC synergy, with probe ultrasound giving maximal phenolic recovery. The extract, rich in rosmarinic acid, chlorogenic acid, and catechin, exhibited antioxidant, antimicrobial ...

A thorny evolution: first Triassic ammonoid with a ventral apertural elongated rostrum
Abstract Ornamented terminal peristomes are common in ammonoids, but pronounced conch projections are rare, particularly in the Triassic. A new early Spathian assemblage from southeastern Idaho yielded two ammonoid specimens with an impressive terminal mid‐ventral elongated rostrum, documenting the first Triassic occurrence and one of the few ...

‘AN AUSTRIAN FATE’: TRAUMA, REPRESSION AND WAR IN ADRIAN GOIGINGER'S DER FUCHS (2022)
ABSTRACT This article examines one of the highest‐grossing films in recent years in Austria, Der Fuchs (Adrian Goiginger, 2022), which focuses on the friendship of the protagonist, a Wehrmacht soldier, with an abandoned fox cub, but in the process elides more than four years of the soldier's wartime experience.

Performance of a parabolic trough solar collector
The performance of a South African parabolic trough solar collector (PTSC) module has been characterised using the ASHRAE 93-1986 standard. The collector is designed for component testing and development in a solar energy research programme. Low-temperature testing was performed at Mangosuthu Technikon’s STARlab facility using water as the working ...

Abstract This paper presents a two‐stage model for planning a renewable energy portfolio by balancing economic, social and environmental sustainability goals. The first stage addresses a multi‐objective problem where conflictive impacts generated by the energy portfolios should be optimised according to the corresponding economic, social or ...

Gases as Working Fluid in Parabolic Trough CSP Plants
AbstractThe energetic dimension of actual economy is massively oriented towards the use of fossil fuels: they cover a share of 87% of the energy needs and the trend of this share is increasing, in spite of the commitments adopted by almost all the Countries in the World.

Investigation and review of mirrors reflectance in parabolic trough solar collectors (PTSCs)
As mirrors used in concentrating solar systems influence the thermal efficiency of the systems collectors to a large extent, the reflectance of mirrors plays a critical role in the thermal efficiency of parabolic trough solar collectors.
