Spirometric values in healthy preschool children
(SOC CHILENA PEDIATRIA, 2019)Introduction. Spirometry is the most commonly used test to evaluate lung function. Foreign reference standards are currently available for preschool children. Objectives: 1. To measure spirometric variables in healthy ... -
Differences in knee sensorimotor control by physical activity level and sex
(ATHA COMUNICACAO & EDITORA, 2019)Objective: The aim of this study was to compare the differences in knee sensorimotor control between healthy men and women by measuring the joint position sense (JPS), sensation of muscle tension (steadiness), and onset ... -
SYSTEMATIC REVIEW OF YURCHENKO VAULT KINETIC AND KINEMATIC INDICATORS
(UNIV LJUBLJANA, FAC SPORT, 2019)The aim of this article was based on determining the most relevant kinematic indicators in the Yurchenko vault technique, using the mechanical purposes of each phase as linking elements. A systematic qualitative review was ... -
TRY plant trait database - enhanced coverage and open access
(Wiley-Blackwell, 2020)Plant traits-the morphological, anatomical, physiological, biochemical and phenological characteristics of plants-determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem ... -
Green Edge ice camp campaigns: understanding the processes controlling the under-ice Arctic phytoplankton spring bloom
(COPERNICUS GESELLSCHAFT MBH, 2020)The Green Edge initiative was developed to investigate the processes controlling the primary productivity and fate of organic matter produced during the Arctic phytoplankton spring bloom (PSB) and to determine its role in ... -
Climatic vulnerabilities and ecological preferences of soil invertebrates across biomes
(WILEY, 2020)Unlike plants and vertebrates, the ecological preferences, and potential vulnerabilities of soil invertebrates to environmental change, remain poorly understood in terrestrial ecosystems globally. We conducted a cross-biome ... -
Mantoniella beaufortii and Mantoniella baffinensis sp. nov. (Mamiellales, Mamiellophyceae), two new green algal species from the high arctic(1)
(WILEY, 2020)Members of the class Mamiellophyceae comprise species that can dominate picophytoplankton diversity in polar waters. Yet, polar species are often morphologically indistinguishable from temperate species, although clearly ... -
Factors associated with sarcopenia: A cross-sectional analysis using UK Biobank
(ELSEVIER IRELAND LTD, 2020)Introduction: The critical sociodemographic, lifestyle and diseases factors influencing sarcopenia, defined by the current European Working Group on Sarcopenia 2 (EWGSOP2) classification and cut-off points, have not yet ... -
Climatic controls of decomposition drive the global biogeography of forest-tree symbioses
(NATURE PUBLISHING GROUP, 2019)The identity of the dominant root-associated microbial symbionts in a forest determines the ability of trees to access limiting nutrients from atmospheric or soil pools(1,2), sequester carbon(3,4) and withstand the effects ... -
Synthesis and characterization of new spirobisindane-based poly(imide)s: Structure effects on solubility, thermal behavior, and gas transport properties
(WILEY, 2020)Two new poly(imide)s (PIs) are derived from a biphenylspirobisindane-diamine monomer and the commercial dianhydrides: 4,4 '-hexafluoroisopropyliden diphthalic anhydride (6FDA) and pyromellitic anhydride (PMDA). Using ... -
Non-canonical function of IRE1 alpha determines mitochondria-associated endoplasmic reticulum composition to control calcium transfer and bioenergetics
(NATURE PUBLISHING GROUP, 2019)Mitochondria-associated membranes (MAMs) are central microdomains that fine-tune bioenergetics by the local transfer of calcium from the endoplasmic reticulum to the mitochondrial matrix. Here, we report an unexpected ... -
Cryopreservation of stallion semen: Effect of adding antioxidants to the freezing medium on sperm physiology
(WILEY, 2020)Cryopreservation of stallion semen has not reached the level of efficiency and positive results described in other species. This is mainly due to the greater sensitivity of stallion sperm to the freezing process, showing ... -
Andrographolide Reduces Neuroinflammation and Oxidative Stress in Aged Octodon degus
(SPRINGER, 2020)Alzheimer's disease (AD) is a devastating neurodegenerative disorder in which superior brain functions, such as memory and cognition, are impaired. Currently, no effective treatment is available for AD. Although andrographolide ... -

Influence of porosity on high-velocity mass-asymmetric collisions
(OXFORD UNIV PRESS, 2020)Using granular mechanics, we study the influence of porosity on the collisions of spherical granular aggregates with a mass ratio of around 60. At high filling factors, the projectile produces a crater on the target, similar ... -
A characterization for some type-2 fuzzy strong negations
(ELSEVIER, 2020)P. Hernandez et al. in 2014 established the axioms that an operation must fulfill in order to be a negation on a bounded poset (partially ordered set). In this work, we focus on the set L of the membership degrees of the ... -
Intensity enhancement of ferromagnetic resonance modes in exchange coupled magnetic multilayers
(IOP PUBLISHING LTD, 2020)In this work, the ferromagnetic resonance characteristics of a NiFeCu/Non-magnetic(NM)/NiFe/NM/CoFe/NM/Co multilayer is studied from a theoretical point of view, and comparisons with the ferromagnetic resonance of a ... -
Climate signals in tree rings of Paubrasilia echinata (Leguminosae-Caesalpinioidea) from the Atlantic Forest of Brazil
(SPRINGER HEIDELBERG, 2020)Key message Tree-ring chronologies were built for wild and cultivated Paubrasilia echinata, a presently endangered species. Significantly P. echinata showed measurably different growth patterns related to the environment ... -
