Hybrid system simulation to supply heated air to a solar food dryer
(2020) [Artículo de periódico]The intermittence of solar radiation, due to continuous rainy or cloudy days, is a limitation of simple and small solar dryers. These conditions often make them impossible to use. By including storage systems (thermal ... -
A hybrid zone of the genus Ctenomys : a case study in southern Brazil
(2012) [Artículo de periódico]We describe variation at microsatellite loci and the chromosomal polymorphisms of a hybrid population, and hybridizing populations of Ctenomys minutus (the minor tuco-tuco) from the coastal plain of Rio Grande do Sul, ... -

Hydration and anomalous solubility of the Bell-Lavis model as solvent
(2012) [Artículo de periódico]We address the investigation of the solvation properties of the minimal orientational model for water originally proposed by [Bell and Lavis, J. Phys. A 3, 568 (1970)]. The model presents two liquid phases separated by a ... -
Hydration and interactions between C3S and C3A polymorphs in the presence of different calcium sulfates
(2021) [Tesis de maestría]Calcium sulfate is an important constituent in Portland cement nowadays. It is used to control the setting time of Portland cement. However, many questions about the role of calcium sulfate on the cement phases (C3A and ... -
Hydraulic and water quality model for a river network
(1978) [Tesis]A river network system consisting of branches and loops is sometimes complicated by downstream effects from tides, lakes, and because of this, management of water quality, sediment control, and floods, in such rivers is a ... -
