Journal of Fish Biology, EarlyView.Abstract Triploidy is an effective tool for producing sterile fishes but often results in impaired performance in commercial aquaculture. In light of this, our study compared the physiological response to exhaustive exercise in juvenile diploid and triploid Arctic charr Salvelinus alpinus, a polar species with great potential for aquaculture.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Experimental Physiology, EarlyView.Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Turbulent Shear Flow in Hydrostatic Thrust Bearings
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1980 This paper is concerned with the effects of a turbulent flow in hydrostatic thrust bearings. Applying an equation representing the "low of wall" to the three-dimensional turbulent shear flow, the local velocity distributions between a rotating disk and a fixed wall are calculated as a function of Reynolds number, local pressure gradient and the ratio ...

Biomechanics and Evolution of the Primate Tongue
Evolutionary Anthropology: Issues, News, and Reviews, Volume 35, Issue 2, June 2026.ABSTRACT Primate tongue morphology and function are critical to understanding the evolution of feeding, swallowing, and vocalization. In this paper, we examine the primate tongue as a muscular hydrostat with regionally specialized neuromuscular compartments. We integrate anatomical, kinematic, and biomechanical modeling approaches to analyze how muscle

Comparison of Power and Thrust Performance for a Fixed and Floating Offshore Wind Turbine
Wind Energy, Volume 29, Issue 6, June 2026.ABSTRACT Floating offshore wind turbines have been identified as a critical technology for sustainable electricity generation. Wind resource assessment is used to determine optimal locations for floating wind farms. However, current methodologies do not account for performance differences between fixed and floating turbines due to wind‐ and wave ...

Terrestrial Analogs to Titan for Geophysical Research
Reviews of Geophysics, Volume 64, Issue 2, June 2026.Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...
