The search for anti-infective activity in the antipyretic plant Senecio smithioides was conducted. Petroleum ether (PE), dichloromethane (CH

Circularly polarized light with high degree of circularity and low azimuthal error sensitivity.

Applied optics

Vilas JL, Bernabeu E, Sanchez-Brea LM, Espinosa-Luna R.
PMID: 24922413
Appl Opt. 2014 Jun 01;53(16):3393-8. doi: 10.1364/AO.53.003393.

The generation of circularly polarized light with a high circularity degree and low azimuthal error sensitivity was analyzed using a system composed by two waveplates. It is shown how the high circularity degree is achieved using a combination of...

Systematic Study of the Content of Phytochemicals in Fresh and Fresh-Cut Vegetables.

Antioxidants (Basel, Switzerland)

Alarcón-Flores MI, Romero-González R, Vidal JL, Frenich AG.
PMID: 26783709
Antioxidants (Basel). 2015 May 06;4(2):345-58. doi: 10.3390/antiox4020345.

Vegetables and fruits have beneficial properties for human health, because of the presence of phytochemicals, but their concentration can fluctuate throughout the year. A systematic study of the phytochemical content in tomato, eggplant, carrot, broccoli and grape (fresh and...

Modeling cell adhesion and proliferation: a cellular-automata based approach.

Advanced modeling and simulation in engineering sciences

Vivas J, Garzón-Alvarado D, Cerrolaza M.
PMID: 27429904
Adv Model Simul Eng Sci. 2015;2:32. doi: 10.1186/s40323-015-0053-5. Epub 2015 Dec 02.

BACKGROUND: Cell adhesion is a process that involves the interaction between the cell membrane and another surface, either a cell or a substrate. Unlike experimental tests, computer models can simulate processes and study the result of experiments in a...

Amplitude equation and pattern selection in Faraday waves.

Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics

Chen P, Viñals J.
PMID: 11969795
Phys Rev E Stat Phys Plasmas Fluids Relat Interdiscip Topics. 1999 Jul;60(1):559-70. doi: 10.1103/physreve.60.559.

A nonlinear theory of pattern selection in parametric surface waves (Faraday waves) is presented that is not restricted to small viscous dissipation. By using a multiple scale asymptotic expansion near threshold, a standing wave amplitude equation is derived from...

[Dr. D. Nicasio Landa, official epidemic doctor during the cholera epidemic of 1854-1855].

Anales del sistema sanitario de Navarra

Viñes JJ.
PMID: 12886322
An Sist Sanit Navar. 2000 Jan-Apr;23(1):85-107. doi: 10.23938/ASSN.0731.

In this unpublished work from 1861, which we have transcribed, Dr. Nicasio Landa (1830-1891) is revealed to have been at the forefront in carrying out epidemiological studies in Spain. He traced the medical topography, or geographical pathology, of cholera...

Domain coarsening of stripe patterns close to onset.

Physical review. E, Statistical, nonlinear, and soft matter physics

Boyer D, Viñals J.
PMID: 11735879
Phys Rev E Stat Nonlin Soft Matter Phys. 2001 Nov;64(5):050101. doi: 10.1103/PhysRevE.64.050101. Epub 2001 Oct 25.

We study domain coarsening of two-dimensional stripe patterns by numerically solving the Swift-Hohenberg model of Rayleigh-Bénard convection. Near the bifurcation threshold, the evolution of disordered configurations is dominated by grain-boundary motion through a background of largely immobile curved stripes....

Sulfonated macro-RAFT agents for the surfactant-free synthesis of cerium oxide-based hybrid latexes.

Journal of colloid and interface science

Garnier J, Warnant J, Lacroix-Desmazes P, Dufils PE, Vinas J, van Herk A.
PMID: 23866196
J Colloid Interface Sci. 2013 Oct 01;407:273-81. doi: 10.1016/j.jcis.2013.06.037. Epub 2013 Jun 27.

Three types of amphiphatic macro-RAFT agents were employed as compatibilizers to promote the polymerization reaction at the surface of nanoceria for the synthesis of CeO2-based hybrid latexes. Macro-RAFT copolymers and terpolymers were first synthesized employing various combinations of butyl...

Analytical determination of the bifurcation thresholds in stochastic differential equations with delayed feedback.

Physical review. E, Statistical, nonlinear, and soft matter physics

Gaudreault M, Drolet F, Viñals J.

Analytical expressions for pitchfork and Hopf bifurcation thresholds are given for a nonlinear stochastic differential delay equation with feedback. Our results assume that the delay time τ is small compared to other characteristic time scales, not a significant limitation...

Controlling the sex ratio is essential in finfish farming. A balanced sex ratio is usually good for broodstock management, since it enables to develop appropriate breeding schemes. However, in some species the production of monosex populations is desirable because...
