The four elements in Robert Grosseteste's De Impressionibus Elementorum

, 2013
In De Impressionibus Elementorum, a treatise written by Grosseteste shortly after 1220, we can find a discussion of some phenomena involving the four classical elements (air, water, fire and earth), in the framework of an Aristotelian physics of the ...

Breeding in natural nesting sites can improve the resilience of local Lesser Kestrel (Falco naumanni) populations to environmental changes

Ibis, Volume 168, Issue 2, Page 465-478, April 2026.
The identification of key habitats of threatened species and of extrinsic environmental factors that influence their resilience to human‐induced environmental changes are the foundation for the definition of conservation objectives. Using the presence and numerical abundance data collected in a long‐term survey (2000–24) of breeding colonies of Lesser ...

Canalized to heat, plastic to cold: adaptive coordination of leaf and seed strategies in populations spanning an elevational gradient

New Phytologist, Volume 250, Issue 2, Page 873-884, April 2026.
Summary In tropical mountains, surviving temperature extremes demands finely tuned strategies. We investigated how populations of the bromeliad Pitcairnia flammea across a 2200 m elevational gradient balance genetic canalization and plasticity, and whether thermal strategies are coordinated between seeds and leaves.

Temperature Influence of the Molar Excess Volume for Polyalkylene Glycol–Water Lubricants Systems

Chemical Engineering &Technology, Volume 49, Issue 3, March 2026.
Understanding how water alters volumetric behavior in advanced lubricants is essential for future energy systems. This study demonstrates how temperature and pressure govern the molecular interactions in a PAG–water lubricant mixture, explains the transition from compact molecular packing to expansion, and highlights important implications for ...

Suplementação de vitamina C associada à densidade de criação no desempenho de frangos de corte Vitamin C supplementation associated to floor space on broiler performance

Scientia Agricola, 1993
Avaliou-se o efeito da suplementação da vitamina C (75 e 150 mg/kg) na alimentação de frangos de corte machos sob condições de estresse de calor e superlotação. As aves foram criadas sobre "cama" de cavaco de madeira nas lotações de 10 e 14 aves/m².
