And then there was us Et puis nous sommes apparus

Journal of the Royal Anthropological Institute, EarlyView.
In 1987, the academic conference ‘Origins and Dispersals of Modern Humans: Behavioural and Biological Perspectives’ was held in Cambridge, UK. Subsequently referred to as the ‘Human Revolution’ conference, this meeting brought together the most prominent academics working in the field of human origins, including archaeologists and palaeoanthropologists,

Modelli previsionali di dispersione delle emissioni da traffico in ambito urbano [PDF]

, 2011
Nel corso dei secoli l'aumento della mobilità è stato comunemente associato al miglioramento della qualità della vita. Per contro, l’emissione di composti in atmosfera da parte dei veicoli a motore comporta la generazione di una pressione negativa sull ...

An integrated approach to balance freshwater connectivity restoration and invasion risk

Conservation Biology, EarlyView.
Abstract Habitat fragmentation negatively affects many native migratory fish populations. However, this fragmentation can also prevent the spread and establishment of invasive species. We modified the dendritic connectivity index (DCI), a commonly used freshwater connectivity metric, to account for multiple invasive dispersal pathways in estimates of ...

Sulla dispersione anomala delle onde magneto-idrodinamiche

Annals of Geophysics, 1959
E noto clie le onde magneto-idrodinamiche hanno una notevoleimportanza in questioni di fisica cosmica in generale e di geofisica inparticolare.La possibile esistenza di tali onde fu posta in evidenza da II. Alfvénnel 1942.

SSZ‐13‐Zeolith mit Isolierten Co2+‐Zentren als ein Effizientes und Beständiges Katalysatorsystem für die Nichtoxidative Ethandehydrierung

Angewandte Chemie, Volume 138, Issue 7, 9 February 2026.
Für die nichtoxidative Ethandehydrierung zu Ethen wurden Katalysatoren mit isolierten Co2+‐Spezies in den 6MR‐ (Co2+‐Z2) und 8MR‐Fenstern ([Co(OH)]+‐Z) eines SSZ‐13‐Zeolithen hergestellt. Die Co2+‐Z2‐Spezies zeigten im Vergleich zu den [Co(OH)]+‐Spezies eine unerwartet hohe Ethenbildungsgeschwindikeit.

Forest structure and connectivity drive the functional recovery of seed rain

Journal of Ecology, Volume 114, Issue 2, February 2026.
Local forest structure and landscape‐scale connectivity shape distinct but complementary pathways of the functional recovery of seed rain in tropical forests. Structural complexity promotes functionally diverse plant–frugivore interactions locally, while connectivity facilitates the arrival of late‐successional seeds from external sources.
