Changing patterns of colonisation and persistence during the wolf recolonisation of the human‐dominated Italian alpine region

open access: yesEcography, EarlyView.
Dynamic occupancy models are fundamental for understanding complex species recolonisation processes, as they allow the assessment of both colonisation and persistence probabilities over time. Using a dynamic occupancy model and a large‐scale multi‐year dataset on wolf presence collected in the Italian alpine region between 2014 and 2020, we analysed ...

Variable length connecting rod

open access: yes, 2016
A variable length connecting rod for an engine comprises a floating bush slidably mounted within a body of the connecting rod with chambers on opposing sides of the bush.

Maximising trait evenness promotes the recovery of plant species richness in managed grasslands

open access: yesEcography, EarlyView.
Land‐use intensification threatens biodiversity, and restoring degraded ecosystems remains challenging due to the difficulty of identifying the rules governing community assembly and dynamics. Investigating the temporal dynamics of trait‐abundance distributions (TADs) along long‐term time series offers a promising approach to disentangle the influence ...

Plant adaptive strategies respond to environmental change across European grassland habitats

open access: yesEcography, EarlyView.
Grassland ecosystems are facing rapid and ongoing change driven by intensified land‐use and accelerated climate change, highlighting the urgent need to understand their potential adaptation and response to environmental change. We analyzed data from 52 980 vegetation plots spanning all major grassland habitats in Europe (including alpine, rocky, sandy,

The influence of a bearing bush mass in sliding bearings with a floating ring on dynamic properties of rotating sets in turbochargers

open access: yesIndian Journal of Science and Technology, 2010
From the point of generation of oscillation, a turbocharger is a self-general system. The essential source of oscillations is the rotating set together with bearings. To deal with the subject, the author developed the model of the rotating set. A shaft with rotors is placed in sliding bearings with floating rings.

Pre‐industrial land‐use limits contemporary shrub encroachment in the French Alps

open access: yesEcography, EarlyView.
Shrub encroachment has become a global phenomenon in recent decades. While global warming in the Arctic is often cited as the primary cause, human‐managed mountain regions have experienced intense historical land‐use that may also play a considerable role.

Model Development and Stability Analysis for a Turbocharger Rotor System under Multi-Field Coupled Forces

open access: yes
Automotive turbochargers have been widely applied in vehicles in order to increase the power output of internal combustion engines by increasing the air to fuel ratio entering the piston cylinders.

低給油圧力の浮動ブシュ軸受における高速安定性(第1報)―安定性に対する内側油膜給排油部の影響―

open access: yes, 2008
Floating bush journal bearings are widely used to support small-sized high-speed rotating machinery. When the supplied pressure is low, the bearing shows peculiar phenomena.

Stability Limit of Electrified Droplets

open access: yes, 2019
In many physical processes, including cloud electrification, electrospray, and demulsification, droplets and bubbles are exposed to electric fields and may either remain whole or burst in response to electrical stresses.

Simulating past and future refugia for temperate trees in northern Italy

open access: yesEcography, EarlyView.
During the Quaternary, trees responded to the climatic changes of glacial–interglacial cycles with large‐scale range shifts. Over cold glacials, temperate tree species contracted their ranges and survived in areas known as refugia. Several studies point to the Euganean Hills (Colli Euganei), in Veneto, northern Italy, as one of the northernmost ...
