Blood flow in the internal jugular veins during the spaceflight - Is it actually bidirectional?
2020
Recently intriguing results of the research performed on astronauts of the International Space Station have been published. Unexpectedly, in some crew members a stagnant and bidirectional flow in the internal jugular vein was found, and in one of the astronauts this vein seemed to be totally thrombosed. If it actually were the case that in the settings of weightlessness there is a substantial risk of jugular vein thrombosis, any long-term human space missions would be extremely dangerous. Yet, we interpret these findings differently. In our opinion, what has been explained as bidirectional flow, actually represented the flow separation, and what has been described as occluded vein was rathe…
Gauge theory of the long-range proximity effect and spontaneous currents in superconducting heterostructures with strong ferromagnets
2017
We present the generalized quasiclassical theory of the long-range superconducting proximity effect in heterostructures with strong ferromagnets, where the exchange splitting is of the order of Fermi energy. In the ferromagnet the propagation of equal-spin Cooper pairs residing on the spin-split Fermi surfaces is shown to be governed by the spin-dependent Abelian gauge field which results either from the spin-orbital coupling or from the magnetic texture. This additional gauge field enters into the quasiclassical equations in superposition with the usual electromagnetic vector potential and results in the generation of spontaneous superconducting currents and phase shifts in various geometr…
Microscopic Revelation of Charge-Trapping Sites in Polymeric Carbon Nitrides for Enhanced Photocatalytic Activity by Correlating with Chemical and El…
2019
The influences of chemical and electronic structures on the photophysical properties of polymeric carbon nitrides (PCNs) photocatalysts, which govern the microscopic mechanisms of the superior photocatalytic activity under visible-light irradiation, have been resolved in this work. Time-resolved photoluminescence and in situ electron paramagnetic resonance measurements indicate that the photoexcited electrons in the fractured PCNs swiftly transfer to the C2p-localized states where the trapped photoelectrons exhibit longer lifetime compared to those in the ordinary PCNs. Moreover, the structure deviation at the carbon (Cb) atoms around the bridging sites of heptazine ring units, where trappe…
Genome-wide diversity and runs of homozygosity in the “Braque Français, type Pyrénées” dog breed
2018
Objective Braque Français, type Pyrénées is a French hunting-dog breed whose origin is traced back to old pointing gun-dogs used to assist hunters in finding and retrieving game. This breed is popular in France, but seldom seen elsewhere. Despite the ancient background, the literature on its genetic characterization is surprisingly scarce. A recent study looked into the demography and inbreeding using pedigree records, but there is yet no report on the use of molecular markers in this breed. The aim of this work was to genotype a population of Braque Français, type Pyrénées dogs with the high-density SNP array to study the genomic diversity of the breed. Results The average observed (\docum…
Measuring stress in clinical and nonclinical subjects using a German adaptation of the Perceived Stress Scale
2020
ANTECEDENTES/OBJETIVO: El estrés se percibe de manera diferente entre los individuos, lo que podría ser particularmente cierto para los sujetos no clínicos y clínicos. Por esta razón, probamos una adaptación alemana de la Perceived Stress Scale de 10 ítems (PSS-10) para el ajuste del modelo y la invarianza de la medición en una gran muestra clínica y no clínica. MÉTODO: Realizamos (1) un análisis factorial confirmatorio múltiple (CFA) en 1.248 sujetos no clínicos y 575 pacientes ambulatorios, (2) invarianza de medición con CFA multigrupo, (3) correlaciones con constructos relevantes y (4) cálculos de la consistencia interna para la escala general y las subescalas Desvalidez y Autoeficacia. …

Mothers’ and fathers’ well-being, parenting styles, and their children’s cognitive and behavioural strategies at primary school
1998
One-hundred and five 6- to 7-year-old children were given a test measuring their helplessness, failure expectations, task-irrelevant behaviour, lack of persistence and search for social support in a classroom setting in order to examine the impact of parental well-being and parenting styles on the children’s cognitive and behavioural strategies at school. Both parents were also asked to fill in scales measuring their depression, parenting stress and parenting styles. The results revealed that maternal depressive symptomatology was associated with their children’s use of maladaptive strategies, whereas paternal depression was not. Moreover, maternal authoritative parenting styles and authori…
The development of achievement strategies and academic skills during the first year of primary school
2002
Abstract The aim of the study was to investigate whether children's achievement strategies would predict the development of their reading and mathematical skills during the first school year, or whether it is rather these skills that predict the changes in their achievement strategies. One-hundred and five 6- to 7-year-old children were examined three times during their first year of primary school: in each measurement, their self-reported achievement strategies were assessed, and their reading and mathematical skills were rated by their classroom teacher. Their overall cognitive competence was also measured before entry into school. The results showed that the use of maladaptive achievemen…
