A synergy of the nutritional additives taurine and silymarin in salmon farming: evaluation with the CHSE-214 cellular model
(Springer Netherlands, 2020-06)The use of additives in the feed industry for producing fish has become the focus of constant change and research. The formulation of a product as a feeding strategy leads to the use of more than one molecule with particular ... -
A relic of the past: current genetic patterns of the palaeoendemic tree Nothofagus macrocarpa were shaped by climatic oscillations in central Chile
(Oxford University Press, 2020-10)Background and Aims The Mediterranean-type forest of central Chile is considered a 'biodiversity hotspot' and a relic of a wider ancient distribution produced by past climatic oscillations. Nothofagus macrocarpa. commonly ... -
A Project Based Learning Approach for Teaching Artificial Intelligence to Undergraduate Students
(Chile. Universidad MayorTempus Publications, 2020)This work presents an active learning methodology called Project-based learning (PBL) for developing artificial intelligence (AI) in a computer vision course of an undergraduate engineering degree. The objective of the ... -
A multispecies assessment of wildlife impacts on local community livelihoods
(Wiley, 2021-02)Conflicts between the interests of agriculture and wildlife conservation are a major threat to biodiversity and human well-being globally. Addressing such conflicts requires a thorough understanding of the impacts associated ... -
Towards an analytical description of active microswimmers in clean and in surfactant-covered drops
(Chile. Universidad Mayor, 2020)Geometric confinements are frequently encountered in the biological world and strongly affect the stability, topology, and transport properties of active suspensions in viscous flow. Based on a far-field analytical model, ... -
Transcriptomic analysis at organ and time scale reveals gene regulatory networks controlling the sulfate starvation response ofSolanum lycopersicum
(Chile. Universidad Mayor, 2020)Background Sulfur is a major component of biological molecules and thus an essential element for plants. Deficiency of sulfate, the main source of sulfur in soils, negatively influences plant growth and crop yield. The ... -
Trends in marijuana use in two Latin American countries: an age, period and cohort study
(Chile. Universidad Mayor, 2020)Background and Aims Uruguay and Chile have the highest levels of marijuana use in Latin America, and have experienced consistent increases during the last two decades. We aim to calculate separate age-period-cohort (APC) ... -
Tri-functional oligomeric polyesters prepared from new dicarboxylic acids containing several amino acids residues by Higashi methodology: synthesis, characterization, and study of solubility and thermal behavior
(Chile. Universidad Mayor, 2021)The synthesis of polyfunctional aliphatic oligomeric polyesters (poly(ether-imido-esters;PEIEs) containing several amino acid residues is described, and their thermal properties and solubility behavior were studied. The ... -
Two Centuries of Hydroclimatic Variability Reconstructed From Tree-Ring Records Over the Amazonian Andes of Peru
(Chile. Universidad Mayor, 2020)Almost half of the tributaries of the Amazon River originate in the tropical Andes and support large populations in mountain regions and downstream areas. However, it is difficult to assess hydroclimatic conditions or to ... -
Understanding gold toxicity in aerobically-grown Escherichia coli
(Chile. Universidad Mayor, 2020)Background There is an emerging field to put into practice new strategies for developing molecules with antimicrobial properties. In this line, several metals and metalloids are currently being used for these purposes, ... -
Understanding How Much TV is Too Much: A Nonlinear Analysis of the Association Between Television Viewing Time and Adverse Health Outcomes
(Chile. Universidad Mayor, 2020)Objective: To inform potential guideline development, we investigated nonlinear associations between television viewing time (TV time) and adverse health outcomes. Methods: From 2006 to 2010, 490,966 UK Biobank participants, ... -
Understanding the Stability of Hollow Nanoparticles with Polycrystalline Shells
(Chile. Universidad Mayor, 2020)The existence of polycrystalline shells has been widely reported in the synthesis of hollow nanoparticles; however, the exact role displayed by the grain boundaries on the stability has been scarcely studied. By including ... -
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 ... -
Varieties of Skills Profiles in Latin America: A Reassessment of the Hierarchical Model of Capitalism
