The Great American Biotic Interchange: A paleoecological review considering neotropical mammals and birds
(Asociacion Espanola de Ecologia Terrestre, 2018-01-01)
Under classical point of view, the formation of the Panama Isthmus during Pliocene (3 Ma ago) would have allowed the species interchange between North America and South America. This ecological and evolutionary process ...
Body image (BI) and coping strategies (CS): Analysis of medical and surgical characteristics in women diagnosed with breast cancer
(Sociedad Chilena de Psicologia Clinica, 2018-05-16)
From a non-experimental transverse design, we sought to identify the possible relationship between BI and CS, and their differences according to surgical-medical variables (surgical intervention, time of diagnosis and stage ...
Deviations to Tri-Bi-Maximal mixing in the limit of μ − τ symmetry
(Elsevier B.V., 2019-07-10)
In the limit of an approximate μ−τ symmetry in the neutrino mass matrix, we explore deviations to the Tri-Bi-Maximal mixing pattern in the neutrino sector. We consider two different ansatzes for the corrected pattern to ...
Evaluation of the antimicrobial activity of cationic peptides loaded in surface-modified nanoliposomes against foodborne bacteria
(MDPI AG, 2019-02-05)
Bacteria are a common group of foodborne pathogens presenting public health issues with a large economic burden for the food industry. Our work focused on a solution to this problem by evaluating antibiotic activity against ...
Decrease of antimicrobial resistance through polyelectrolyte-coated nanoliposomes loaded with β-lactam drug
(MDPI AG, 2019-03-01)
Currently, one of the greatest health challenges worldwide is the resistance to antibiotic drugs, which has led to the pursuit of new alternatives for the recovery of biological activity, where the use of different types ...
Benefits of SpinBOT playful robotic environment in the development of cognitive abilities
(Universitat Politecnica de Valencia, 2019-01-01)
Children with physical disabilities are at high risk of developing adverse effects on their cognitive development, due to their lack of ability to interact with the world around them. Multiple studies have demonstrated the ...
Conductimetry: A rapid alternative technique for chlorides determination in cheese
(Pontificia Universidad Javeriana, 2019-04-10)
The correlation of two instrumental techniques for chlorides determination in Colombian cheese, Queso Molido Nariñense (a type of white cheese), was analyzed. Potentiometry of chloride precipitation is the standard technique ...
Intercultural components in the multimodal structure of a language learning website
(Universidad Nacional de Colombia, 2019-01-01)
The emergence of language learning websites has generated changes in intercultural communicative practices. Particularly, these sites use a wide variety of modes of communication (visual, linguistic, spatial) which allow ...
New factorization relations for nonlinear sigma model amplitudes
(American Physical Society, 2019-02-15)
We obtain novel factorization identities for nonlinear sigma model amplitudes using a new integrand in the Cachazo-He-Yuan double-cover prescription. We find that it is possible to write very compact relations using only ...
New factorization relations for Yang-Mills amplitudes
(American Physical Society, 2019-01-15)
A double-cover extension of the scattering equation formalism of Cachazo, He, and Yuan leads us to conjecture covariant factorization formulas of n-particle scattering amplitudes in Yang-Mills theories. Evidence is given ...
