Chemical signatures in fin spine edge of Atlantic bluefin tuna (Thunnus thynnus) can serve as habitat markers of geographically distinct marine environments
; ; ; ; ; ; ; Murua Auricenea, Hilario; ; ; (Elsevier, 2022-11)
Chemical fingerprints in otoliths are commonly used as natural habitat markers in fishes. Alternatively, the first dorsal fin spine can provide valuable chemical information and may be more suitable for studying (i) ... -
Closed G2 forms and special metrics
(2015-07-10)En esta tesis se aborda el estudio y construcción de variedades G2 calibradas. Una tal variedad es una variedad de Riemann, de dimensión 7, con una métrica de Riemann definida por una cierta 3-forma diferencial, denominada ... -
Closing the loop: Waste valorisation from vegetal sources to develop fruit active films
; ; Guerrero Manso, Pedro Manuel; De la Caba Ciriza, María Coro (Elsevier, 2024-07)
Cellulose-rich residue after agar extraction was incorporated into gelatin film forming formulations in order to revalorize it and improve film properties. This revalorized cellulose was compared with the commercial sodium ... -
