Development of an Efficient CVT using Electromecanical System

, 2009
Continuously variable transmission (CVT) is a type of automatic transmission that can change the gear ratio to any arbitrary setting within the limits.

From biology to biotechnology: Host‐regulation factors from parasitoid wasps are a source of bioactive molecules with translational potential

Insect Molecular Biology, EarlyView.
Parasitoid wasps deploy maternal and embryonic factors to reprogramme host physiology. Venom, calyx fluid, polydnaviruses, teratocytes and larval secretions act in a coordinated, compartmentalised manner. Host‐regulation factors are promising sources of insecticidal, antimicrobial and bioinspired translational molecules.

Alla scoperta delle CVT

, 2010
Le trasmissioni Cvt, da Continuously Variable Transmission, ovvero trasmissione a variazione continua di velocità, si stanno diffondendo sempre di più nel mondo dei trattori. Al di là delle singole soluzioni tecniche adottate dai vari costruttori, in

Age and growth of the spiny butterfly ray Gymnura altavela (Elasmobranchii, Gymnuridae) in the Southwest Atlantic (in situ) and under human care in a public aquarium (ex situ): Plasticity and population patterns

Journal of Fish Biology, EarlyView.
Abstract This study provides the first age and growth assessment of the endangered spiny butterfly ray, Gymnura altavela (Linnaeus, 1758), in the Southwest Atlantic, while also updating the growth parameters (asymptotic disc width—DW∞ and growth coefficient—k) estimated in an ex situ a marine aquarium setting.

Effects of 14 days of head‐down bed rest with or without exercise, and subsequent recovery on bone turnover, density and structure in older adults

Experimental Physiology, EarlyView.
Abstract Bed rest accelerates bone loss and may exacerbate skeletal fragility. This study examined the effects of 14 days of head‐down tilt bed rest (HDBR) with or without exercise, and subsequent recovery, on bone turnover, density and structure in older adults. Twenty‐two healthy older adults (55–65 years) completed the HDBR protocol.

Age‐ and sex‐specific modulation of human cardiac electrophysiology by doxorubicin

The Journal of Physiology, EarlyView.
Abstract figure legend DOX differentially impacts cardiac electrophysiology based on sex and age. Sex differences were primarily observed among younger hearts, where action potential duration (APD) prolongation was observed in females, but not in males. Created using BioRender. George, S. (2026) https://BioRender.com/wresf1k Abstract Acute doxorubicin (

Bridging and Rewiring Mechanisms in the Deconstruction of the Functional Architecture of Fish Assemblages in the Upper Paraná River Basin by Non‐Native Species

Ecology of Freshwater Fish, Volume 36, Issue 1, January 2027.
ABSTRACT Freshwater ecosystems harbour nearly half of all known fish species yet rank among the most threatened on the planet, with biological invasion operating as one of the primary functional destabilizers in systems where dam cascades have already dismantled natural biogeographical barriers. In the Upper Paraná River basin, which supports high fish

Size Matters: Barrier Heights and Widths in the Kinetics Of Tautomerisation and Rotamerisation of Thiotropolone and Its Five‐ and Three‐Membered Cyclic Analogues

International Journal of Chemical Kinetics, Volume 58, Issue 12, Page 1109-1116, December 2026.
ABSTRACT Recent experiments by Nunes et al. have demonstrated that unprecedented control of chemical reactions is possible by narrowband infrared vibrational photo‐excitation at low temperatures in inert matrices. The generated higher energy level conformers may then undergo rotamerisation and tautomerisation reactions which provide extremely useful ...
