(Universidad Catolica Silva Henriquez, 2019)The reading attitudes of primary students have proven to be relevant in their reading performance, so measuring them is fundamental to raise the level. The objective of this study was to validate and adapt the instrument ...
-
(Universidad Catolica Silva Henriquez, 2019)The present paper explores three topics that are complementary to the study of demonyms we have carried out in two previous essays (Kordic Riquelme and Chávez Fajardo: 2017; and Chávez Fajardo and Kordic Riquelme (in press). ...
-
(Springer New York LLC, 2019)We have recently reported that global perinatal asphyxia (PA) induces a regionally sustained increase in oxidized glutathione (GSSG) levels and GSSG/GSH ratio, a decrease in tissue-reducing capacity, a decrease in catalase ...
-
(Institute of Physics Publishing, 2019)We describe a new method to derive clean, iodine-free spectra directly from observations acquired using high-resolution echelle spectrographs equipped with iodine cells. The main motivation to obtain iodine-free spectra ...
-
(Elsevier Inc., 2019)Surface texturing is a promising approach to tailor friction and wear between rubbing surfaces in mechanical components. In this study, surface textures with different geometries and shapes were fabricated on hardened steel ...
-
(Public Library of Science, 2019)Paper mulberry, Broussonetia papyrifera (L.) L’Hér. ex Vent. (Moraceae), a dioecious species, was transported by humans from Taiwan to the islands of Remote Oceania. Its introduction and cultivation in Remote Oceania was ...
-
(MDPI AG, 2019)Avocado oil has generated growing interest among consumers due to its nutritional and technological characteristics, which is evidenced by an increase in the number of scientific articles that have been published on it. ...
-
(Servicio de Publicaciones de la Universidad de Navarra, 2019)This article analyzes the post-toponymic demonym from a morphological point of view. As is well known, because of its suffixal richness and of its derivational possibilities in Spanish, the morphological level is the most ...
-
(NLM (Medline), 2019)Antarctic and Subantarctic lakes are unique ecosystems with relatively simple food webs, which are likely to be strongly affected by climate warming. While Antarctic freshwater invertebrates are adapted to extreme environmental ...
-
(TUBITAK, 2019)We establish a characterization of the Lyapunov and Mittag-Leffler stability through (fractional) Lyapunov functions, by proving converse theorems for Caputo fractional order systems. A hierarchy for the Mittag-Leffler ...
-
(Sociedad Medica de Santiago, 2019)This review analyzes the effects of high intensity interval training (HIIT) on muscle and cardiovascular fitness and body composition in teenagers. A search was carried out in international databases, finding 145 papers ...
-
(Routledge, 2019)Chile is recognized in the educational policy field as one of the first laboratories of neoliberal initiatives. These policies, initiated under the dictatorship of Augusto Pinochet, did not change with the new democratic ...
-
(MDPI AG, 2019)In this paper, a deep learning (DL)-based physical (PHY) layer authentication framework is proposed to enhance the security of industrial wireless sensor networks (IWSNs). Three algorithms, the deep neural network (DNN)-based ...
-
(MDPI AG, 2019)Dehydration in rodents induces anorexia. In humans however, the role of dehydration in energy intake is controversial. This study investigated the effect of extreme fluid restriction on acute energy intake during and after ...
-
(Institute of Electrical and Electronics Engineers Inc., 2019)Currently, the diagnosis of schizophrenia is made solely based on interviews and behavioral observations by a trained psychiatrist. Technologies such as electroencephalography (EEG) are used for differential diagnosis and ...
-
(Elsevier GmbH, 2019)Background: Dendritic cells (DCs) are usually immunogenic, but they are also capable of inducing tolerance under anti-inflammatory conditions. Immunotherapy based on autologous DCs loaded with an allogeneic melanoma cell ...
-
(Institute of Physics Publishing, 2019)The Cosmology Large Angular Scale Surveyor (CLASS) is mapping the polarization of the cosmic microwave background (CMB) at large angular scales (2 < ℓ ≲ 200) in search of a primordial gravitational wave B-mode signal ...
-
(Birkhauser Verlag AG, 2019)Air temperature records provide strong evidence of change and variability in the climate system. The sensitivity of temperature to changes throughout the year renders it an ideal object of study when seeking to identify ...
-
(Mosby Inc., 2019)Introduction: Laparoscopic Nissen fundoplication is the preferred operative treatment for patients with gastroesophageal reflux disease. The most recent published results only refer to clinical evaluations and few discuss ...
