Experimental verification of position-dependent angular-momentum selection rules for absorption of twisted light by a bound electron
(IOP Publishing, 2018-02)
We analyze the multipole excitation of atoms with twisted light, i.e, by a vortex light field that carries orbital angular momentum. A single trapped 40Ca+ ion serves as a localized and positioned probe of the exciting ...
Plant functional traits, herbivore selectivity and response to sheep grazing in Patagonian steppe grasslands
(Wiley Blackwell Publishing, Inc, 2005-02)
1. In some ecosystems there is a positive feedback between forage quality and grazing intensity. This involves three components of plant tolerance to grazing: functional traits, herbivore selectivity and response to grazing. ...
A mixed model of the evolution of polygyny and sexual size dimorphism in mammals
(Wiley Blackwell Publishing, Inc, 2020-01)
The theory of sexual selection is the most widely accepted theory explaining the evolution of mating systems and secondary sexual characters. Polygyny is the most common mating system in mammals, and there is a strong ...
Thermographic inspection using a microcontroller-based camera positioning system
(2015-01-01)
Infrared thermal cameras can be used to detect early-stage thermal anomalies in electrical or mechanical equipment and structures, before they lead to the interruption of their operation. In this work, we present a system ...
Correlation between mastitis occurrence and the count of microorganisms in bulk raw milk of bovine dairy herds in four selective culture media
(CAMBRIDGE UNIV PRESS, 2010)
Milk is the normal secretion of the mammary gland, practically free of colostrum and obtained by the complete milking of oil(? or more healthy animals. Mastitis is all inflammatory process of the mammary gland and it may ...
