(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 ...
-
(Universidad de Chile, 2021-07)La interacción antagónica que involucra a las plantas y sus insectos herbívoros es un proceso ecológico con un gran impacto sobre la biodiversidad y el funcionamiento de los ecosistemas terrestres. En distintas regiones ...
-
(Universidad de Chile, 2021)En las últimas décadas ha empezado a surgir un mayor interés en conocer el comportamiento ambiental de ciertos compuestos orgánicos aprobados para su uso cotidiano, principalmente debido a que se han ido conociendo sus ...
-
(Universidad de Chile, 2021)Las nanopartículas de plata se han impuesto por sobre otras nanopartículas metálicas como cobre y oro, debido a su alta estabilidad, facilidad de funcionalización y actividad antibacteriana excepcional. Existen en la ...
-
(Universidad de Chile, 2021)Las turberas son un tipo de humedal que se caracteriza por presentar materia orgánica acumulada llamada turba. También presentan vegetación dominante compuesta por musgos del género Sphagnum. Son humedales que se caracterizan ...
-
(2021)La ictiofauna chilena es un grupo de alto valor sistemático y muy amenazado, siendo una gran preocupación su manejo y conservación. En este contexto, modelos de distribución de especies (SDM) se han utilizado para predecir ...
-
(Universidad de Chile, 2021)En cianobacterias unicelulares, se ha demostrado que el reloj circadiano influye en la temporalidad con que ocurren ciertos procesos celulares tales como la fotosíntesis, respiración celular, división celular, entre otros. ...
-
(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 ...
-
(Universidad de Chile, 2021-01-25)El bosque siempreverde de Aysén, al igual que todos los ecosistemas, está sujeto a la variación estacional de condiciones ambientales tales como la temperatura, las precipitaciones, la radiación UV-B, la intensidad de ...
-
(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 ...
-
(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 ...
-
(Oxford University Press, 2020)Heterozygosity-fitness correlations (HFCs) have been used to monitor the effects of inbreeding in threatened populations. HFCs can also be useful to investigate the potential effects of inbreeding in isolated relict ...
-
(Elsevier, 2020)A pilot study was initiated in 2018 under the Global Atmospheric Passive Sampling (GAPS) Network named GAPS-Megacities. This study included 20 megacities/major cities across the globe with the goal of better understanding ...
-
(UNAM, Fac. Ciencias Politicas & Sociales, 2020)The study of policies of memory regarding human rights violations in military dictatorships, armed conflicts and civil wars in recent world history has had an important boom in recent decades, constituting grounds for ...
-
(Nature, 2020)Mechanical properties of nanomaterials, such as nanowires and nanotubes, are an important feature for the design of novel electromechanical nano-architectures. Since grain boundary structures and surface modifications can ...
