Eco-physiological aspects of melaleuca seed germination
(2013-07-30)
The invasive behavior of melaleuca (Melaleuca quinquenervia) plants in wetlands is due to its aggressive regeneration strategy, which is based on its seeds germination performance. Understanding of the eco-physiological ...
Exploring nu signals in dark matter detectors
(IOP PUBLISHING LTDBRISTOL, 2012)
We investigate standard and non-standard solar neutrino signals in direct dark matter detection experiments. It is well known that even without new physics, scattering of solar neutrinos on nuclei or electrons is an ...
Automatic dark fibres detection in wool tops
(2003)
Is proposed a method for the automatic detection of dark fibres in wool tops based on image processing. A software which implements this method was developed, composed by five modules: KL projection, light correction, Gabor ...
Zebrafish preference for light or dark is dependent on ambient light levels and olfactory stimulation
(MARY ANN LIEBERT INC, 2011)
Access to electric light is associated with shorter sleep duration in a traditionally hunter-gatherer community
(SAGE Publications, 2015-08)
Access to electric light might have shifted the ancestral timing and duration of human sleep. To test this hypothesis, we studied two communities of the historically hunter-gatherer indigenous Toba/Qom in the Argentinean ...
Economic analysis of the implementation of an LED lighting system in a dark house: A case study
(2017-04-01)
The use of the Light Emitting Diode (LED) in broiler chicken production is a trend practically irreversible as it happened with the use of compact fluorescent light (FCL) in substitution of the incandescent lamps. As LED ...
Search for dark sector by repurposing the UVX Brazilian synchrotron
(Institute for Ionics, 2023-06)
We propose the first Search for Dark Sector at the Brazilian Synchrotron Light Laboratory, site of Sirius, a fourth-generation storage ring. We show that UVX, Sirius predecessor, can be a promising dark sector detector, ...
Influence of light/dark cycle and orexins on breathing control in green iguanas (Iguana iguana)
(2020-12-01)
Light/dark cycle affects the physiology of vertebrates and hypothalamic orexin neurons (ORX) are involved in this function. The breathing pattern of the green iguana changes from continuous to episodic across the light/dark ...
Cosmological constraints on scalar field dark matter
(2021-01-01)
This paper aims to put constraints on the parameters of the Scalar Field Dark Matter (SFDM) model, when dark matter is described by a free real scalar field filling the whole universe, plus a cosmological constant term. ...
Entrainment of circadian rhythms to irregular light/dark cycles: A subterranean perspective
(Nature Publishing Group, 2016-10)
Synchronization of biological rhythms to the 24-hour day/night has long been studied with model organisms, under artificial light/dark cycles in the laboratory. The commonly used rectangular light/dark cycles, comprising ...
