Recently, we reported the production of Cadmium sulfide (CdS) fluorescent semiconductor nanoparticles (quantum dots, QDs) by acidophilic bacteria of the Acidithiobacillus genus. Here, we report that the addition of inorganic ...
Nuclear DNA content in the red conger eel Genypterus chilensis (Guichenot, 1881) (Actinopterygii: Ophidiidae)
(Universidad de Concepción, 2011)
Studies about nuclear DNA content in the genus Genypterus are scarce, and the present study gives the first estimate of nuclear DNA content of Genypterus chilensis, with a value of 2C= 1.0 + 0.06 pg, value close to that ...
On the Chemical Abundances of Miras in Clusters: V1 in the Metal-rich Globular NGC 5927
(Institute of Physics Publishing, 2018-03)
We present the first spectroscopic abundance determination of iron, α-elements (Si, Ca, and Ti), and sodium for the Mira variable V1 in the metal-rich globular cluster NGC 5927. We use high-resolution (R ∼ 28,000), high ...
