NATURALISTIC SCOPES OF AN ASTRONOMICAL EXPEDITION: JAMES MELVILLE GILLISS AND THE INSTITUTIONALIZATION OF SCIENCE IN CHILE (1849-1852)
(PONTIFICA UNIV CATOLICA CHILE, INST HISTORIA, 2019)In 1849 the U.S. Naval Astronomical Expedition, headed by Lieutenant James Melville Gilliss, arrived in Chile with the mission to register observations that, triangulated with those carried out in the northern hemisphere, ... -
Negative feelings and behaviour are associated with low nutritional level, unhealthy lifestyle, and cardiometabolic risk factors in Chilean schoolchildren
(Chile. Universidad Mayor, 2020)Background: feelings and behaviours are an important tool that should be considered to prevent early unhealthy lifestyles. Objective: the objective was to determine the association between feelings (i.e., sadness, loneliness, ... -
Neighbourhood landscape context shapes local species richness patterns across continents
(WILEY, 2023-06)Aim: Recent studies highlight the importance of linking landscape ecology and macroecology for a better understanding of broad-scale biodiversity patterns. The "landscape context effect" denotes that species responses and ... -
Nelson Quichillao, Twitter and the class struggle
(UNIV CATOLICA TEMUCO, 2018)Currently there is a growing number of researches which describe the transformations of political mobilization in the asst century. Those researches are distinguished due to the widespread growth of digital communication ... -
Neogene Patagonian magmatism between the rupture of the Farallon plate and the Chile Ridge subduction
(PERGAMON-ELSEVIER SCIENCE LTD, 2021-10)Based on chemical composition and timing of late Paleogene and Neogene igneous rocks in southern Patagonia, six igneous suites are identified and correlated with subduction processes during the approaching and subduction ... -
Neonatal glucocorticoid overexposure alters cardiovascular function in young adult horses in a sex-linked manner
(Cambridge University Press, 2021-04)Prenatal glucocorticoid overexposure has been shown to programme adult cardiovascular function in a range of species, but much less is known about the long-term effects of neonatal glucocorticoid overexposure. In horses, ... -
Network approach identifies Pacer as an autophagy protein involved in ALS pathogenesis
(BMC, 2019)BackgroundAmyotrophic lateral sclerosis (ALS) is a multifactorial fatal motoneuron disease without a cure. Ten percent of ALS cases can be pointed to a clear genetic cause, while the remaining 90% is classified as sporadic. ... -
Neural crest E-cadherin loss drives cleft lip/palate by epigenetic modulation via pro-inflammatory gene-environment interaction
(Nature Publishing Group, 2023-05-24)Gene-environment interactions are believed to play a role in multifactorial phenotypes, although poorly described mechanistically. Cleft lip/palate (CLP), the most common craniofacial malformation, has been associated with ... -
Neurocognitive Disorders in Heart Failure: Novel Pathophysiological Mechanisms Underpinning Memory Loss and Learning Impairment
(SPRINGER, 2019)Heart failure (HF) is a major public health issue affecting more than 26 million people worldwide. HF is the most common cardiovascular disease in elder population; and it is associated with neurocognitive function decline, ... -
Neuronal HIF-1 alpha in the nucleus tractus solitarius contributes to ventilatory acclimatization to hypoxia
(Wiley-Blackwell Publishing Ltd, 2020-05)We hypothesized that hypoxia inducible factor 1 alpha (HIF-1 alpha) in CNS respiratory centres is necessary for ventilatory acclimatization to hypoxia (VAH); VAH is a time-dependent increase in baseline ventilation and the ... -
New and interesting chaetothyrialean fungi from Spain
(CIENCIAS, 2016)In the course of taxonomic studies on saprobic microfungi from Spain, several slow-growing, dematiaceous hyphomycetes were isolated from soil, submerged plant material and river sediments. Sixteen of these strains were ... -
New He-3 neutron monitor for Chilean Cosmic-Ray Observatories from the Altiplanic zone to the Antarctic zone.
(CIENCIAS, 2012)We present the results of three years of continuous operations and the principal characteristics of our new He-3 neutron monitors installed in the Chilean Network of Cosmic-Ray Observatories. During the years 2004 and 2005, ... -
New Hybrid Copper Nanoparticles/Conjugated Polyelectrolyte Composite with Antibacterial Activity
(MDPI, 2021-02)In the search for new materials to fight against antibiotic-resistant bacteria, a hybrid composite from metallic copper nanoparticles (CuNPs) and a novel cationic pi-conjugated polyelectrolyte (CPE) were designed, synthesized, ... -
New Negations on the Membership Functions of Type-2 Fuzzy Sets
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2019)Type-2 fuzzy sets (T2FSs) were introduced by L. A. Zadeh in 1975 as an extension of type-1 fuzzy sets (T1FSs). In this extension, the degree to which an element belongs to a set is just a label of the linguistic ... -
New Poly(imide)s Bearing Alkyl Side-Chains: A Study on the Impact of Size and Shape of Lateral Groups on Thermal, Mechanical, and Gas Transport Properties
(MDPI AG, 2020-07)A set of five new aromatic poly(imide)s (PIs) incorporating pendant acyclic alkyl moieties were synthesized. The difference among them was the length and bulkiness of the pendant group, which comprises of linear alkyl ...
