What season suits you best? Seasonal light changes and cyanobacterial competition
(Instituto de Física de Líquidos y Sistemas Biológicos, 2015-03-29)
Nearly all living organisms, including some bacterial species, exhibit biological processes with a period of about 24 h called circadian (from the Latin circa, about and dies, day) rhythms. These rhythms allow living ...
A proposal to teach light in a unified framework using the Feynman method
(Scientia Socialis, 2012-06)
The goal of this proposal is to teach the basic aspects of light from the point of view of quantum mechanics at high school level. To this end, we have adapted Feynman´s Path Integral Method of Quantum Mechanics. This is ...

Differential adaptation of two varieties of common bean to abiotic stress - II. Acclimation of photosynthesis
(OXFORD UNIV PRESS, 2006-02)
The photosynthetic characteristics of two contrasting varieties of common bean (Phaseolus vulgaris) have been determined. These varieties, Arroz and Orfeo, differ in their productivity under stress conditions, resistance ...
Impact of thermal bridging on the performance of buildings using Light Steel Framing in Brazil
(Netherlands, 2014-03-07)
The Light Steel Framing building technology was introduced in Brazil in the late 1990s for the
construction of residential houses. Because the design system was imported from the United States and is
optimised to work ...
Light modulates the melanophore response to alpha-MSH in Xenopus laevis: An analysis of the signal transduction crosstalk mechanisms involved
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2010)
Melanin granule (melanosome) dispersion within Xenopus laevis melanophores is evoked either by light or alpha-MSH. We have previously demonstrated that the initial biochemical steps of light and alpha-MSH signaling are ...
Light-related photosynthetic characteristics of lotic macroalgae
