The role of natural mineral particles collected at one site in Patagonia as immersion freezing ice nuclei
(Elsevier Science Inc, 2018-05-15)
This work studies the role of mineral particles collected in the region of Patagonia (Neuquén, Argentina) as ice nuclei particles (INPs) by immersion freezing mode. The particle immersion-freezing ability was analyzed under ...
Water movement caused by spreading surfactants in unsaturated systems of particles of nonuniform size
(Taylor & Francis, 2007-04-27)
The movement of water originated by the spreading of two surfactants was analyzed in glass beads as well as on soil systems, both of particles of nonuniform size The higher difference of surface tension produced in the ...
Influence of particle size on the conductance of SnO2 thick films
(Elsevier, 2003-03-06)
The electrical response of SnO2 thick films was found to be highly dependent on the grain size. This result can be explained as the consequence of the type of intergranular potential barriers developed at intergrains. ...
Electrokinetics of charged spherical colloidal particles taking into account the effect of ion size constraints
(Academic Press Inc Elsevier Science, 2011-04)
The electrokinetic properties of suspended spherical particles are examined using a modified standard electrokinetic model, which takes into account the finite ion size and considers that the minimum approach distance of ...
Flow rate of polygonal grains through a bottleneck: Interplay between shape and size
(Consejo Nacional de Investigaciones Científicas y Técnicas. Centro Científico Tecnológico Conicet La Plata. Instituto de Física de Líquidos y Sistemas Biológicos, 2015-11-13)
We report two-dimensional simulations of circular and polygonal grains passing through an aperture at the bottom of a silo. The mass flow rate for regular polygons is lower than for disks, as observed by other authors. We ...

Particle Size and Hydration Properties of Dried Apple Pomace: Effect on Dough Viscoelasticity and Quality of Sugar-Snap Cookies
(Springer, 2019-07)
Apple pomace (AP) is a by-product of the juice industry, rich in dietary fiber (45.06%), which is generated in large quantities. The objectives of the present work were to evaluate the effect of the particle size and the ...
HDL colesterol, protector de enfermedad cardiovascular: calidad vs. cantidad
(Universidad Privada Norbert WienerPE, 2019-09-25)
Los estudios pioneros de Framingham mostraron una relación inversa entre los niveles bajos de HDL Colesterol y la morbilidad coronaria. Los ensayos con modificaciones en el estilo de vida han mostrado un muy discreto ...
Gluten-free breadmaking affected by the particle size and chemical composition of quinoa and buckwheat flour fractions
(Sage Publications Ltd, 2019-12)
This study aimed at assessing the effect of physicochemical properties and the particle size of different fractions of buckwheat and quinoa on the behaviour of gluten-free dough and bread quality. Quinoa and buckwheat ...
