Simulation of the Reactivation of Partially Inactivated Biocatalysts in Sequential Batch Reactors
(MDPI AG, 2020-11)The enzymatic reactivation process enables the recovery of catalytic activity for inactive biocatalysts. However, its effect on the specific productivity of the processes has not been studied. The main objective of this ... -
Short-term effects of variable-density thinning on regeneration in hardwood-dominated temperate rainforests
(Chile. Universidad Mayor, 2020-05)Second-growth temperate forests usually have simpler composition and structure than comparable old-growth stands. We evaluated the application of variable density thinning (VDT) as a way to increase old-growth attributes, ... -
Shear transformation zones structure characterization in Cu50Zr50 metallic glasses under tensile test
(Elsevier, 2020-11)The atomic structure of Cu50Zr50 metallic glasses under tensile test was investigated using molecular dynamics simulations. Voronoi polyhedra analysis was employed to calculate the number of neighbors for each atom, obtained ... -
Self-Compatibility Not Associated with Morphological or Genetic Diversity Reduction in Oil-Rewarding Calceolaria Species
(MDPI Multidisciplinary Digital Publishing Institute, 2020-10)One of the most common evolutionary transitions in angiosperms is the reproductive change from outcrossing to selfing, commonly associated with changes in floral biology and genetic diversity. Here, we aim to test whether ... -
Socio-demographic patterns of public, private and active travel in Latin America: Cross-sectional findings from the ELANS study
(Elsevier BV, 2020-03)Background: Active travel such as walking or cycling has been associated with more favorable health outcomes. However, evidence on patterns of transportation in Latin America is scarce. Therefore, the aim of this study was ... -
Sources and diffusive air-water exchange of polycyclic aromatic hydrocarbons in an oligotrophic North-Patagonian lake
(Elsevier, 2020-10)Polycyclic aromatic hydrocarbons (PAHs) are semivolatile organic compounds of environmental concern. This study aims to investigate the influence of local sources of anthropogenic PAHs and their air-water exchange fluxes ... -
Spatio-Temporal Variation of the Urban Heat Island in Santiago, Chile during Summers 2005-2017
(MDPI Multidisciplinary Digital Publishing Institute, 2020-10)Urban heat islands (UHIs) can present significant risks to human health. Santiago, Chile has around 7 million residents, concentrated in an average density of 480 people/km(2). During the last few summer seasons, the highest ... -
Child maltreatment and cardiovascular disease: quantifying mediation pathways using UK Biobank
(BioMed Central Ltd., 2020-06)BackgroundChild maltreatment is associated with cardiovascular disease (CVD), but mediation pathways have not been fully elucidated. The aim of the current study was to determine and quantify the underlying pathways linking ... -
Axonal Degeneration in AD: The Contribution of A beta and Tau
(Frontiers Media S.A., 2020-10)Alzheimer's disease (AD) represents the most common age-related neurodegenerative disorder, affecting around 35 million people worldwide. Despite enormous efforts dedicated to AD research over decades, there is still no ... -
Associations of fat and carbohydrate intake with cardiovascular disease and mortality: prospective cohort study of UK Biobank participants
(BMJ Publishing Group, 2020-03)Objective - To investigate the association of macronutrient intake with all cause mortality and cardiovascular disease (CVD), and the implications for dietary advice. Design - Prospective population based study. Setting - ... -
Association of injury related hospital admissions with commuting by bicycle in the UK: prospective population based study
(BMJ Publishing Group, 2020-03)OBJECTIVE: To determine whether bicycle commuting is associated with risk of injury. DESIGN: Prospective population based study. SETTING: UK Biobank. PARTICIPANTS: 230390 commuters (52.1% women; mean age 52.4 years) recruited ... -
Association Between Walking Pace and Stroke Incidence Findings From the UK Biobank Prospective Cohort Study
(Lippincott Williams and Wilkins Ltd., 2020-05)Background and Purpose- Stroke incidence in younger and middle-aged people is growing. Despite this, its associations in this subset of the stroke population are unknown, and prevention strategies are not tailored to meet ... -
Height growth-rate at a given height: A mathematical perspective for forest productivity
(Elsevier, 2020-09)Understanding the height growth of trees is a fundamental component for scientific knowledge and management of forest ecosystems. The height of dominant trees at a reference-age, commonly known as the site-index, is the ... -
Distinct oxygen environments shape picoeukaryote assemblages thriving oxygen minimum zone waters off central Chile
(Oxford University Press, 2020-09)Oxygen minimum zones (OMZs) support ocean biogeochemical cycles of global importance. The OMZ off central Chile is characterized by seasonally variable oxygen concentrations due to upwelling events. Bacterial and archaeal ... -
Discriminative learning and associative memory under the differential outcomes procedure is modulated by cognitive load
(Elsevier, 2020-07)Working memory (WM) has been thought to be the cause of associative memory deficits in older adults. Previous research has demonstrated the benefits of a discriminative learning procedure, the differential outcomes procedure ... -
Deciphering the functional diversity of DNA-binding transcription factors in Bacteria and Archaea organisms
(Public Library of Science, 2020-08)DNA-binding Transcription Factors (TFs) play a central role in regulation of gene expression in prokaryotic organisms, and similarities at the sequence level have been reported. These proteins are predicted with different ... -
Core-periphery dynamics in a plant-pollinator network
