(Univ Basque Country UPV-EHU Press, Spain, 2021)Jorge E. Allende is a biochemist trained in the United States of America who has been a professor at the University of Chile since 1961. He has served in many leadership positions in both Chilean and international scientific ...
-
(Univ. Valparaíso Facultad Ciencias Mar Recursos Naturales, Chile, 2021)Alfredo Llaña Garín, Profesor de Estado en Ciencias Biológicas y Química de la Universidad de Chile (1937), es el precursor del estudio de las algas marinas en Chile. Esta reseña recuerda sus inicios, su pionera investigación ...
-
(MDPI, 2021)Pollution due to acidic and metal-enriched waters affects the quality of surface and groundwater resources, limiting their uses for various purposes. Particularly, manganese pollution has attracted attention due to its ...
-
(MDPI, 2021)This article describes the synthesis and characterization of beta-cyclodextrin-based nano-sponges (NS) inclusion compounds (IC) with the anti-tumor drugs melphalan (MPH) and cytoxan (CYT), and the addition of gold nanoparticles ...
-
(Frontiers Media, 2021)Turbulence in space plasmas usually exhibits two regimes separated by a spectral break that divides the so called inertial and kinetic ranges. Large scale magnetic fluctuations are dominated by non-linear MHD wave-wave ...
-
(American Physiological Society, 2021)The rise of microscopy in the seventeenth century allowed scientists to discover a new world of microorganisms and achieve great physiological advances. One of the first microscopes of the epoch was Antonie van Leeuwenhoek's ...
-
(Frontiers Media, 2021)Communication with bacteria deeply impacts the life history traits of their hosts. Through specific molecules and metabolites, bacteria can promote short- and longterm phenotypic and behavioral changes in the nematode ...
-
(MDPI, 2021)Reductions in crop yields brought about by abiotic stress are expected to increase as climate change, and other factors, generate harsher environmental conditions in regions traditionally used for cultivation. Although ...
-
(Springer, 2021)The lack of winter cold is a severe limitation for the cultivation of grapevines (Vitis vinifera L) in areas with warm winter climates. This phenomenon is currently becoming quite important due to global warming, which ...
-
(MDPI, 2021)One of the fundamental open questions in plasma physics is the role of non-thermal particles distributions in poorly collisional plasma environments, a system that is commonly found throughout the Universe, e.g., the solar ...
-
(Nature, 2021)We examine a fractional discrete nonlinear Schrodinger dimer, where the usual first-order derivative in the time evolution is replaced by a non integer-order derivative. The dimer is nonlinear (Kerr) and PT-symmetric, and ...
-
(MDPI, 2021)Following an injury, axons of both the central nervous system (CNS) and peripheral nervous system (PNS) degenerate through a coordinated and genetically conserved mechanism known as Wallerian degeneration (WD). Unlike ...
-
(MDPI, 2021)Changes in the level of hydrogen peroxide (H2O2) is a good indicator to monitor fluctuations in cellular metabolism and in the stress responses. In this study, the changes in H2O2 content during bud endodormancy (ED) and ...
-
(MDPI, 2021)Drugs are widely used as therapeutic agents; however, they may present some limitations. To overcome some of the therapeutic disadvantages of drugs, the use of beta-cyclodextrin-based nanosponges (beta CDNS) constitutes a ...
-
Studies on the solvatochromic effect and NLO response in new symmetric bimetallic Rhenium compounds (Pergamon-Elsevier, 2020)In the search of novel coordination complexes with enhanced nonlinear optical activity, symmetrical bimetallic Rhenium complexes incorporating polypyridine plane bridging ligands are reported. The complexes studied were ...
-
(Univ Valparaíso Facultad Ciencias mar Recursos Naturales, 2020)Rapa Nui only allows artisanal fishery activities, but these often go unaware. The market is centralized on Pacific chub, snoek and yellowfin tuna, all common pelagic fish. On September 2016, one un-identified specimen ...
-
(Elsevier, 2020)Sarcoptic mange has been anecdotally reported in Chilean wildlife during the last decade. Although thisdisease can have devastating outcomes for biodiversity, there is no comprehensive assessment of thispotential threat ...
-
(Amer Chemical Soc, 2020)Characterization and control of surfaces and interfaces are critical for photovoltaic and photocatalytic applications. In this work, we propose CH3NH3PbI3 (MAPI) perovskite slab models whose energy levels, free of quantum ...
-
(Springer Heidelberg, 2020)Let T be a complex torus and G a finite group acting on T without translations such that T/G is smooth. Consider the subgroup F <= G generated by elements that have at least one fixed point. We prove that there exists a ...
-
(Universidad de Concepción, Chile, 2020)Some biogeographical features of bryophytes associated with subtropical-temperate ecosystems in Chile are examined, including diversity, concentration of species richness, endemism, biogeographical composition and disjunctions. ...
