Use of Fura 2 Fluorescent Dyes as Indicator for Studying Calcium Distribution in Several Plant Tissues
(CIENCIAS, 2010)Calcium (Ca) is an essential plant nutrient and is important in determining quality of fruits in storage. The analytical method presently known to determine Ca concentration in vegetables measures total Ca, and there is a ... -
Using classical Cepheids to study the far side of the Milky Way disk: I. Spectroscopic classification and the metallicity gradient
(Chile. Universidad Mayor, 2020)Context. Much of what we know about the Milky Way disk is based on studies of the solar vicinity. The structure, kinematics, and chemical composition of the far side of the Galactic disk, beyond the bulge, are still to be ... -
Using Ecological Modelling to Assess the Long-Term Survival of the West-Indian Manatee (Trichechus manatus) in the Panama Canal
(Chile. Universidad Mayor, 2020)There is evidence of a thriving population of West-Indian manatee (Trichechus manatus) in the Panama Canal, although it is not clear if they are descendants of a small group of introduced manatees or if manatees have entered ... -
Using Femtosecond Laser Irradiation To Grow the Belly of Gold Nanorods
(AMER CHEMICAL SOC, 2018)Irradiation of gold nanorods can lead to the formation of several new nanostructures. One of the most interesting among them are phi-shaped rods, a stable intermediate shape in the rod-to-sphere conversion process, but not ... -
Using remote sensing to detect whale strandings in remote areas: The case of sei whales mass mortality in Chilean Patagonia
(Chile. Universidad Mayor, 2019)We test the ability of Very High Resolution satellite (VHR) imagery to detect stranded whales using both manual and automated methods. We use the 2015 mass mortality event in the Gulf of Penas locality, central Patagonia, ... -
