This research makes a brief review of the limnology lakes in wetlands Western Amazon, associating physical-chemical and morphological aspects to biodiversity black-waters whitewaters lakes. Lakes these areas can show different patterns vertical stratification, both dissolved oxygen concentration temperature. Furthermore, there are mixing patterns. These events depend mainly on way connect river...

A numerical study based on large eddy simulation is performed to investigate a bottom boundary layer under an oscillating tidal current. The focus is on the boundary layer response to an external stratification. The thermal field shows a mixed layer that is separated from the external stratified fluid by a thermocline. The mixed layer grows slowly in time with an oscillatory modulation by the t...

The neutrally stable atmospheric surface layer is used as a physical model of a very high Reynolds number, canonical turbulent boundary layer. Challenges and limitations with this model are addressed in detail, including the inherent thermal stratification, surface roughness and non-stationarity of the atmosphere. Concurrent hot-wire and sonic anemometry data acquired in Utah's western desert p...

introduction: domestic animals are invaluable resources to study the molecular architecture of complex traits. although the mapping of quantitative trait loci (qtl) underlying economically important traits in domestic animals has achieved remarkable results in recent decades, not all of the genetic variation in the complex traits has been captured due to the low density of markers used in qtl m...

The motion of temperature dependent viscosity and thermal conductivity of steady incompressible laminar free convective (MHD) non-Newtonian Casson fluid flow over an exponentially stretching surface embedded in a thermally stratified medium are investigated. It is assumed that natural convection is induced by buoyancy and exponentially decaying internal heat generation across the space. The dim...

The leakage of hydrogen in a room is key issue safety, and ventilation plays an important role dispersion. usually builds thermal stratification environment due to the low temperature liquid or throttling effect. This study attempts develop fast-computational theoretical model dispersion motion indoor based on classical buoyant jet carry out experimental verify model. research results show that...
