POLLEN CLUMPING AND WIND DISPERSAL IN AN INVASIVE ANGIOSPERM

Marc Parlange, Charles Vivant Ignacio Meneveau, Michael David Martin

Pollen dispersal is a fundamental aspect of plant reproductive biology that maintains connectivity between spatially separated populations. Pollen clumping, a characteristic feature of insect-pollinated plants, is generally assumed to be a detriment to win ...

Characterization and modeling of twinned dendrite growth

Mario Alberto Salgado Ordorica

The formation of feathery grains during semi-continuous casting of Al-alloys [1, 2] is an interesting problem from both practical and theoretical points of view. These structures are formed by a lamellar sequence of twinned and untwinned regions separated ...

Large eddy simulation of pollen transport in the atmospheric boundary layer

Marc Parlange, Charles Vivant Ignacio Meneveau

This paper presents a framework to simulate pollen dispersal by the wind based on the large eddy simulation(LES) technique. Important phenomena such as the pollen emission by the plants and the ground deposition are parameterized by the lower boundary cond ...

Pollen productivity estimates and relevant source area of pollen for selected plant taxa in a pasture woodland landscape of the Jura Mountains (Switzerland)

Alexandre Buttler, Pascal Vittoz

Relevant source area of pollen (RSAP) and pollen productivity for 11 key taxa characteristic of the pasture woodland landscape of the Jura Mountains, Switzerland, were estimated using pollen assemblages from moss polsters at 20 sites. To obtain robust poll ...

Twinned dendrite growth in binary aluminum alloys

Michel Rappaz, Mario Alberto Salgado Ordorica

The formation of twinned dendrites (feathery grains) in binary Al-Zn, Al-Mg, Al-Cu and Al-Ni alloys has been studied in specimens directionally solidified under identical thermal conditions, i.e. G approximate to 100 K cm(-1), v approximate to 1 mm s(-1), ...
