Increasing the temperature range of dipolar glass polymers through copolymerization: A first approach to dipolar glass copolymers
(Elsevier BV, 2020-08)This work introduces, for the first time, the dipolar glass copolymer concept as a new strategy to develop polymer dielectrics. Methacrylic monomers containing sulfone and nitrile groups were copolymerized with ... -
Indentation and scratching of iron by a rotating tool-a molecular dynamics study
(ELSEVIER, 2021-06-15)When abrasive particles interact with a surface, besides translational center-of-mass motion also rotational motion of the abrasive may be involved. We perform molecular dynamics simulations of the influence of the rotational ... -
Indicadores cinemáticos en el salto de extensión
(Chile. Universidad Mayor, 2017)The aim of this article was determine the most relevant kinematic indicators in technique extension jump used mechanical purpose of each phase as a connecting element. This article used a systematic review with a intend ... -
Indoor postmortem mutilation by dogs: Confusion, contradictions, and needs from the perspective of the forensic veterinarian medicine
(CIENCIAS, 2016)Canine scavenging in indoor settings is rarely reported but is regularly observed in forensic practice. Such scavenging can cause misinterpretation when specific expert witnesses are not called. Forensic investigators must ... -
Inducing Porosity on Hollow Nanoparticles by Hypervelocity Impacts
(American Chemical Society, 2017)The large surface-to-volume ratio of hollow palladium nanoparticles (hNPs) offers room to improve their hydrogen storage capacity as well as their catalytic activity. However, a less explored possibility is to use, in ... -
Induction of IAPP amyloid deposition and associated diabetic abnormalities by a prion-like mechanism
(Rockefeller University Press, 2017)Although a large proportion of patients with type 2 diabetes (T2D) accumulate misfolded aggregates composed of the islet amyloid polypeptide (IAPP), its role in the disease is unknown. Here, we show that pancreatic IAPP ... -
Inervación de los músculos interóseos plantares del pie humano
(CIENCIAS, 2010)Los músculos interóseos plantares son tres y están situados en el plano profundo de la región plantar del pie. Se originan en la base de los metatarsianos y ligamentos cercanos, para insertarse en la base de la tercera, ... -
Infección rinosinusal por Scedosporium apiospermum en un hospedero inmunocompetente
(CIENCIAS, 2009)Las infecciones por Scedosporium sp pueden traducirse en colonización, infecciones localizadas superficiales y profundas, o enfermedad diseminada. Presentamos un caso clínico de infección rinosinusal por Scedosporium ... -
Infection and exposure to vector-borne pathogens in rural dogs and their ticks, Uganda
(CIENCIAS, 2015)Background: In rural parts of Africa, dogs live in close association with humans and livestock, roam freely, and usually do not receive prophylactic measures. Thus, they are a source of infectious disease for humans and ... -
Inflammatory Effects of Edwardsiella ictaluri Lipopolysaccharide Modifications in Catfish Gut
(CIENCIAS, 2014)Bacterial lipopolysaccharides (LPS) are structural components of the outer membranes of Gram-negative bacteria and also are potent inducers of inflammation in mammals. Higher vertebrates are extremely sensitive to LPS but ... -
Influence iron-iron distance on the thermal decomposition of ammonium perchlorate. New catalysts for the highly efficient combustion of solid rocket propellant
(ELSEVIER SCIENCE SA, 2020)Five homobimetallic compounds derived from indacene and p-phenylene ligands with different Fe-Fe distances have been synthesized. The catalytic effect on the thermal decomposition of Ammonium Perchlorate (AP) of each complex ... -
Influence of fatigue and velocity on the latency and recruitment order of scapular muscles
(CHURCHILL LIVINGSTONE, 2018)Objectives: To determine the influence of velocity and fatigue on scapular muscle activation latency and recruitment order during a voluntary arm raise task, in healthy individuals. Design: Cross-sectional study. Setting: ... -
Influence of fire regime on forest structure and restoration of a native forest type in the southern Andean Range
(Chile. Universidad Mayor, 2017)There is convincing scientific evidence that fire regime has been affected by climate change, both in their frequency and severity, consequently causing more ecological and socio-economic impacts. Although fire has played ... -
Influence of lipopolysaccharide outer-core in the intrinsic resistance to antimicrobial peptides and virulence in Edwardsiella ictaluri
(CIENCIAS, 2016)The genus Edwardsiella consists of bacteria with an intrinsic resistance to cyclic cationic antimicrobial peptides (CAMPs). Edwardsiella ictaluri, a pathogen of the catfish (Ictalurus punctatus) and the causative agent of ... -
Influence of mobile genetic elements and insertion sequences in long- and short-term adaptive processes of Acidithiobacillus ferrooxidans strains
(NATURE PORTFOLIO, 2023-07-05)The recent revision of the Acidithiobacillia class using genomic taxonomy methods has shown that, in addition to the existence of previously unrecognized genera and species, some species of the class harbor levels of ... -
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 ... -
Influence of Porosity on the Elastic Modulus of Ti-Zr-Ta-Nb Foams with a Low Nb Content
(MDPI, 2019)The development of titanium foams with a low elastic modulus has increased their scientific and technological relevance due to the evident need to avoid stress shielding problems. In this work, we studied the synthesis and ... -
Influence of squeezing on the weak-to-strong measurement transition
