Turbulent Dufour effect and Onsager-type relations
Physical Review E, 1999 In this paper we extend the work of Elperin et al. [Phys. Rev. Lett. 80, 69 (1998)] by showing that a turbulent Dufour-type effect is also present in chemically nonreacting gaseous admixtures. This result is used to analyze the possibility of obtaining turbulent analogs of the Onsager relations, a fundamental result for molecular crossed effects in ...

On generalized hydromagnetic thermosolutal convection: The Dufour-effect
Thermal Science, 2005 The effect of uniform magnetic field on the Dufour-driven thermosolutal convection of an electrically conducting fluid completely confined in an arbitrary region bounded by rigid walls is considered. Some general qualitative results concerning the character of marginal state, stability of oscillatory motions and limitations on the oscillatory motions ...

Oscillatory double-diffusive convection in a horizontal cavity with Soret and Dufour effects [PDF]
International Journal of Thermal Sciences, 2016 Oscillatory double-diffusive convection in horizontal cavity with Soret and Dufour effects is investigated numerically based on SIMPLE algorithm with QUICK scheme in non-uniform staggered grid system. The results show that double-diffusive convection develops from steady-state convection-dominated, periodic oscillatory, quasi-periodic oscillatory to ...

Ecology and evolution of pyrazines in insects
Biological Reviews, EarlyView.ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

DUFOUR EFFECT IN A DISPERSIVE LIQUID-PHASE MEDIUM IN THE GAUSSIAN BEAM FIELD [PDF]
Физико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2013 The effect of thermal radiation produced when the transparent dispersion medium is under the Dufour effect is analyzed theoretically. Analytical expression describing the dynamics of the medium temperature is received.

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts
Biological Reviews, EarlyView.ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

The Ratio of Helium- to Hydrogen-Atmosphere White Dwarfs: Direct Evidence for Convective Mixing
, 2007 We determine the ratio of helium- to hydrogen-atmosphere white dwarf stars as a function of effective temperature from a model atmosphere analysis of the infrared photometric data from the Two Micron All Sky Survey combined with available visual ...
