Enhancement of Hydrolysis through the Formation of Mixed Heterometal Species: Al3+/CH3Sn3+ Mixtures
2013
ABSTRACT: The hydrolysis of mixed-metal cations (Al3+/CH3Sn3+) was studied in aqueous solutions of NaNO3, at I = 1.00 ± 0.05 mol·dm−3 and T = 298.15 K, by potentiometric technique. Several hydrolytic mixed species are formed in this mixed system, namely, Alp(CH3Sn)q(OH)r with (p, q, r) = (1, 1, 4), (1, 1, 5), (1, 1, 6), (2, 1, 4), (1, 2, 5), (1, 4, 11), (1, 3, 8), and (7, 6, 32). The stability of these species, expressed by the equilibrium: pAl3+ + qCH3Sn3+ + rOH− = Alp(CH3Sn)q(OH)r 3(p+q)−r, βpqr OH, can be modeled by the empirical relationship: log βpqr OH = −3.34 + 2.67p + 9.23(q + r). By using the equilibrium constant Xpqr relative to the formation reaction: pAl(p+q)(OH)r + q(CH3Sn)(p+q…
Otherwise than quantum
2022
AbstractThe paper focuses on two problems with Alexander Wendt's unification of physical and social ontology on the basis of quantum theory. Firstly, by endowing social phenomena with an ontological foundation in physical reality defined in quantum terms Wendt risks reducing a plurality of worlds as ‘fields of sense’, ordered by their immanent rules, to the physical world ordered by the laws of quantum theory. Secondly, by defining his quantum social science as an ontology Wendt risks excluding from consideration all that which violates ontological laws, yet may still be said to exist or take place: event, potentiality, and alterity. Although the advantages of a scientific ontology are indi…
On Jacques Lacan Psychosis Theory and ERPs Analysis
2012
If properly interpreted, some recent neurolinguistic researches based on the so-called Event-Related Potentials (ERPs) and conducted on patients showing schizophrenic spectrum disorders, seem to confirm the main Jacques Lacan theses on psychosis. In this brief note, we simply want put to the attention the existence of this possible and interesting correlation.

Auditory perceptual learning : evidence from electrophysiological recordings in rodents and humans
2018
Yllättävät muutokset äänimaailmassa viestittävät yleensä selviytymisen kannalta tärkeistä vihjeistä, joten niiden nopea ja automaattinen havaitseminen on tärkeää. Tietoinen harjoittelu mahdollistaa havainto-oppimisen ja oppimisen seurauksena hermostoon muodostuu uusia muistijälkiä. Varhaisessa kehityksessä herkkyyskauden aikana muistijälkien muodostuminen, ihmisellä erityisesti puheäänille, on automaattista, eikä siihen vaadita tietoista harjoittelua. Toisaalta perinteisesti on ajateltu, että herkkyyskauden jälkeen vain aktiivinen harjoittelu johtaa uusien muistijälkien muodostumiseen. Muutoksen havaitsemisen hermostollista perustaa voidaan tutkia mittaamalla aivojen sähköisiä jännitevastei…

Neurophysiological markers of subjective memory complaints in healthy people
2022
Con el envejecimiento de la población es importante comprender los cambios neurofisiológicos que se producen. En este contexto, las quejas subjetivas de la memoria (QSM) se están convirtiendo en un tema de interés ya que se han considerado un factor de riesgo para desarrollar trastornos relacionados con demencias como el deterioro cognitivo leve y enfermedad de Alzheimer. Por lo tanto, es importante investigar los biomarcadores tempranos para la detección y la planificación de los tratamientos. En este sentido, el procesamiento de emociones faciales es una importante función cognitiva comúnmente afectada en personas con trastornos relacionados con demencias que podría ayudar a analizar camb…
Concentric force enhancement during human movement
2001
In order to understand the possible mechanisms contributing to enhanced concentric performance in stretch-shortening cycle exercises in vivo the present study examined knee extension torque, EMG activity and fascicle length of the vastus lateralis muscle in maximal and submaximal human movements. Maximal concentric knee extensions (120 s-1) were done after pre-stretch and pre-isometric conditions by nine volunteers. During shortening at the knee angle of 115 (180 = extended) the knee extension torque was found to be greater in pre-stretch condition (272 vs. 248 Nm, p < 0.05) although the torque level prior to shortening was smaller than in pre-isometric condition (268 vs. 314 Nm, p< 0.05…

Logistics potentials of success as the factors affecting firm performance
2019
Firms are permanently looking for ways to achieve expected market and economic outcomes, which are the basis for superior performance as well as strong, long-term competitive advantage. The most important market outcomes are: (1) customer satisfaction, (2) customer loyalty, and (3) marketshare. In turn, the most important economic outcomes are: (1) profit, (2) profitability, and (3) return on investment (ROI). In achieving such performance and advantage the important role is assigned - among others - to the so-called logistics potentials of success. Logistics potentials of success are significant parts of the “general” firm potentials of success, which comprise: (1) resources, (2) capabilit…
