Effects of temperature on feeding and digestive processes in fish

open access: yesTemperature, 2020
As most fish are ectotherms, their physiology is strongly affected by temperature. Temperature affects their metabolic rate and thus their energy balance and behavior, including locomotor and feeding behavior. Temperature influences the ability/desire of

Between Droughts and Floods: The Seasonal Response of Freshwater Snails in Artificial Reservoirs in the Brazilian Semiarid Region

open access: yesPopulation Ecology, EarlyView.
We investigate the seasonal dynamics of two freshwater snails, Biomphalaria straminea and Melanoides tuberculata, in artificial reservoirs of the Brazilian semiarid region. Despite regulated hydrology, B. straminea exhibited strong seasonal fluctuations associated with dry periods, while M. tuberculata maintained stable populations throughout the year,

Conjugate temperatures

open access: yesJournal of Approximation Theory, 1992
The authors study pairs \((u,v)\) of temperatures on \(\mathbb{R}\times]0,\infty[\) that satisfy the equations \[ D_ x u(x,t)=-iD_ t^{1/2} v(x,t) \qquad\text{and}\qquad iD_ t^{1/2} u(x,t)=D_ x v(x,t), \] which are analogous to the Cauchy-Riemann equations; here \(D_ t^{1/2}\) is a Weyl fractional derivative.

Moving in the Dark: Enlightening the Spatial Population Ecology of European Cave Salamanders

open access: yesPopulation Ecology, EarlyView.
We assessed individual interactions, movement ecology and activity patterns of a subterranean population of Speleomantes strinatii, applying spatial capture–recapture modeling to a photographic dataset of 104 individuals. ABSTRACT Space use and movement are fundamental aspects of organisms' ecology, mirroring individual fitness, behavior, and life ...

Epitaxial growth of high-quality GaN with a high growth rate at low temperatures by radical-enhanced metalorganic chemical vapor deposition

open access: yesScientific Reports
Using our recently developed radical-enhanced metalorganic chemical vapor deposition (REMOCVD) technique, we have grown gallium nitride (GaN) on bulk GaN and GaN on Si templates. Three features make up this system: (1) applying very high-frequency power (

Thermal properties of fluoride mixtures near the melting point

open access: yesChimica Techno Acta
The thermal diffusivity of LiF-NaF-KF (FLiNaK), NaF-KF and FliNaK-NdF3 mixtures was studied by laser flash method near the melting point. The obtained results demonstrate that the thermal diffusivity of the melts slowly decreases within a certain ...

Quantum mechanisms for selective detection in complex gas mixtures using conductive sensors

open access: yesScientific Reports, 2023
In this paper, we consider new quantum mechanisms for selective detection in complex gaseous media which provide the highest possible efficiency of quantum sensors and for the first time analyze their nature. On the basis of these quantum mechanisms, the

Temperature-Sombor and Temperature-Nirmala Indices

open access: yesINTERNATIONAL JOURNAL OF MATHEMATICS AND COMPUTER RESEARCH, 2022
In this paper, we introduce the temperature-Sombor index, modified temperature-Sombor index and temperature-Nirmala index of a graph. Also we compute these temperature indices for some standard graphs and tetrameric 1,3-adamantane. Furthermore, we establish some properties of newly defined temperature-Sombor index and temperature-Nirmala index.
