Purpose.This study investigated whether coach-athlete relationship development through sport was influenced by demographic factors, team cohesion, and motivation variables in Brazilian youth sport participants.Methods.The research involved 301 young athletes (136 boys and 165 girls) participating in the final phase of the School Games. They were aged 14–17 years (mean: 16.03 ± 0.83 years). The survey used assessed demographic variables, the Coach-Athlete Relationship Questionnaire, the Sport Motivation Scale, and the Youth Sport Environment Questionnaire. The data were investigated with a cluster analysis, chi-squared test, and multivariate analysis of variance (<i>p</i> < 0.05).Results.The study revealed more female participants in the high coach relationship cluster (<i>p</i> = 0.010), as well as a stronger association of futsal and handball with high coach-athlete relationship quality, and of basketball with low coach-athlete relationship quality (<i>p</i> = 0.002). When compared with the low coach relationship cluster, youth sport participants in the high coach relationship cluster presented higher scores for social cohesion (<i>p</i> = 0.001), task cohesion (<i>p</i> = 0.001), and autonomous motivation regulations (<i>p</i>: 0.003–0.001).Conclusions.Such findings suggest that coaches should seek to encourage group cohesion for both task and social cohesion, thus motivating athletes to meet the demands of the sporting context.

Introduction (statement of the problem and parameters relevance). The composition of the mixture of air and gasoline vapors differs in air and vapors ratio when purging the absorber at different time of the car operation. Therefore, the air-fuel mixture entering the engine for afterburning can create uncertainties in lambda control.The purposeof the research was to determine the main features of lambda regulation in an unstable fuel-air mixture.Methodology and research methods. An analysis of the mixed air and fuel vapor flows entering the engine during absorber purge was made. The composition and quantity effect of this mixture on the excess air coefficient was determined. The main parameters of air and gasoline vapor mixture in the fuel tank vapor space were established.Scientific novelty and results. An equation obtained testifies that the excess air coefficients in the flows of the fuel-air mixture relate to the mixture flow rate during absorber purge. The requirements for the composition of the fuel-air mixture leaving the absorber have been formulated. In order not to exceed these values the threshold values of short-term fuel supply were corrected and the relative mass flow value rate of gasoline vapors from the tank in relation to the air flow rate purge was determined.Practical significance. The factors limiting the flow sections of the absorber gas-air paths and the optimal ratios of the flow sections were determined on the example of a two-chamber absorber to exclude excessive enrichment of the fuel-air mixture entering the engine during purge.

Abstract. At SMEAR II research station in Hyytiälä, located in the Finnish boreal forest, the process of new particle formation and the role of ions has been investigated for almost 20 years near the ground and at canopy level. However, above SMEAR II, the vertical distribution and diurnal variation of these different atmospheric ions are poorly characterized. In this study, we assess the atmospheric ion composition in the stable boundary layer, residual layer, mixing layer, and free troposphere, and the evolution of these atmospheric ions due to photochemistry and turbulent mixing through the day. To measure the vertical profile of atmospheric ions, we developed a tailored set-up for online mass spectrometric measurements, capable of being deployed in a Cessna 172 with minimal modifications. Simultaneously, instruments dedicated to aerosol properties made measurements in a second Cessna. We conducted a total of 16 measurement flights in May 2017, during the spring, which is the most active new particle formation season. A flight day typically consisted of three distinct flights through the day (dawn, morning, and afternoon) to observe the diurnal variation and at different altitudes (from 100 to 3200 m above ground), to capture the boundary layer development from the stable boundary layer, residual layer to mixing layer, and the free troposphere. Our observations showed that the ion composition is distinctly different in each layer and depends on the air mass origin and time of the day. Before sunrise, the layers are separated from each other and have their own ion chemistry. We observed that the ions present within the stable layer are of the same composition as the ions measured at the canopy level. During daytime when the mixing layer evolved and the compounds are vertically mixed, we observed that highly oxidized organic molecules are distributed to the top of the boundary layer. The ion composition in the residual layer varies with each day, showing similarities with either the stable boundary layer or the free troposphere. Finally, within the free troposphere, we detected a variety of carboxylic acids and ions that are likely containing halogens, originating from the Arctic Sea.
Influence of emission size distribution and nucleation on number concentrations over Greater Paris

Published: July 2022

Abstract. With the growing evidence that high particle number concentrations may impact health, modelling their emissions and understanding formation processes is necessary, especially in cities where many people are exposed.
As emission inventories of particle numbers and size distribution over cities are usually not available, a methodology is defined to estimate them from PM2.5 emissions and ratios of PM1 / PM2.5 and PM0.1 / PM2.5 by activity sector.
In this methodology, a fitting parameter αem is used to redistribute the number concentrations in the lowest emission diameter range. This parameter is chosen by comparing measured and simulated number concentrations during non-nucleation days. The emission size distribution is then finely discretised by conserving both mass and number in each of the size ranges where emissions are specified. The methodology is applied over Greater Paris during the MEGAPOLI campaign (July 2009).
Three-dimensional simulations are performed using the chemistry transport model Polair3D/Polyphemus coupled to the aerosol module SSH-aerosol to represent the evolution of particles by condensation, evaporation, coagulation, and nucleation, with a sectional approach for the size distribution. The model is first compared to measurements during non-nucleation days, and the influence over the month of July 2009 of three different nucleation parameterisations is assessed, i.e. binary (sulfuric acid, water), ternary (sulfuric acid, ammonia, water), and heteromolecular (extremely low-volatility organic compounds (ELVOCs) from monoterpenes and sulfuric acid). The modelled number concentrations compare very well to measurements, with an average normalised mean error of 42 % for the daily number concentrations of particles larger than 10 nm and 37 % for the number concentrations of particles larger than 100 nm.
The influence of the binary nucleation is low, and the ternary nucleation scheme leads to better simulated number concentrations (in terms of bias and error) at only one site out of three, but it systematically reduces the model to measurement correlation, suggesting that ternary nucleation may not be the dominant process in new particle formation. However, the relative bias and error, as well as the correlation at suburban sites, are systematically improved using the heteromolecular nucleation scheme involving sulfuric acid and ELVOCs from monoterpenes. This suggests that heteromolecular nucleation may be important in cities, especially at suburban sites in summer, and that a better characterisation of the emissions of ELVOC precursors from traffic is needed.
The impact of hurricane disturbances on a tropical forest: implementing a palm plant functional type and hurricane disturbance module in ED2-HuDi V1.0

Published: July 2022

Abstract. Hurricanes commonly disturb and damage tropical forests. Hurricane frequency
and intensity are predicted to change under the changing climate. The
short-term impacts of hurricane disturbances to tropical forests have been
widely studied, but the long-term impacts are rarely investigated. Modeling
is critical to investigate the potential response of forests to future
disturbances, particularly if the nature of the disturbances is changing
with climate. Unfortunately, existing models of forest dynamics are not
presently able to account for hurricane disturbances. Therefore, we
implement the Hurricane Disturbance in the Ecosystem Demography model (ED2)
(ED2-HuDi). The hurricane disturbance includes hurricane-induced immediate
mortality and subsequent recovery modules. The parameterizations are based
on observations at the Bisley Experimental Watersheds (BEW) in the Luquillo
Experimental Forest in Puerto Rico. We add one new plant functional type
(PFT) to the model – Palm, as palms cannot be categorized into one of the
current existing PFTs and are known to be an abundant component of tropical
forests worldwide. The model is calibrated with observations at BEW using
the generalized likelihood uncertainty estimation (GLUE) approach. The
optimal simulation obtained from GLUE has a mean relative error of −21 %,
−12 %, and −15 % for stem density, basal area, and aboveground biomass,
respectively. The optimal simulation also agrees well with the observation
in terms of PFT composition (+1 %, −8 %, −2 %, and +9 %
differences in the percentages of “Early”, “Mid”, “Late”, and “Palm” PFTs,
respectively) and size structure of the forest (+0.8 % differences in
the percentage of large stems). Lastly, using the optimal parameter set, we
study the impact of forest initial condition on the recovery of the forest
from a single hurricane disturbance. The results indicate that, compared to
a no-hurricane scenario, a single hurricane disturbance has little impact on
forest structure (+1 % change in the percentage of large stems) and
composition (<1 % change in the percentage of each of the four
PFTs) but leads to 5 % higher aboveground biomass after 80 years of
succession. The assumption of a less severe hurricane disturbance leads to a
4 % increase in aboveground biomass.
Ecological niche and potential geographic distributions of Dermacentor marginatus and Dermacentor reticulatus (Acari: Ixodidae) under current and future climate conditions

Abstract. Dermacentor marginatus is a vector disease of both humans and animals and transmits the causative agents of Q fever (Coxiella burnetii) and the spotted fever group (Rickettsia raoultii and R. slovaca), as well as of Crimean–Congo hemorrhagic fever. Dermacentor reticulatus can transmit various pathogens such as Francisella tularensis, Babesia spp., tick encephalitis virus, Coxiella burnetii, Omsk hemorrhagic fever virus, and Rickettsia spp. and can cause serious skin lesions. Herein, ecological niche modeling (ENM) is used to characterize the niches of these two ticks and describe their potential distributional patterns under both current and future climate conditions, as a means of highlighting geographic distributional shifts that may be of public health importance. We assessed distributional implications of five general circulation models (GCMs), under two shared socio-economic pathways (SSP245 and SSP585) for the period 2041–2060. Predictions for D. marginatus showed broad suitable areas across western, central, and southern Europe, with potential for expansion in northern and eastern Europe. Dermacentor reticulatus has suitable areas across western, central, and northern Europe. Under future scenarios, new expansions were observed in parts of northern and eastern Europe and highland areas in central Europe. Despite broad overlap between the niches of the ticks, D. marginatus has a broader niche, which allows it to show greater stability in the face of the changing climate conditions. Areas of potential geographic distributional expansion for these species should be monitored for actual distributional shifts, which may have implications for public health in those regions.
Образ Фауста в творчестве Ференца Листа как воплощение романтического героя
Authors: Есман Ольга Сергеевна , Мирошникова Дарья Николаевна 
Published: July 2022

В данной работе мы стремимся выявить сущность музыкального образа «Фауст» в творчестве Ференца Листа на примере Сонаты H-moll. Обращаясь к трагедии Гёте, композитор обращается не к сюжету, но к образу страстного человеческого ума и сердца и философским вопросам гения, с одной стороны. С другой – как человек своего времени Лист синтезирует гётевскую проблему кризиса познания с романтическим противоречием, лежащим в основе явления в целом. Мы приходим к выводу о том, что композитор осмысляет культурный архетип Фауста и представляет свою концепцию, которая сочетает черты гуманистической трактовки Гёте и типичные черты героя романтической эпохи. Выведены черты концепта «Фауст» по Листу. В контексте проблематики статья является междисциплинарным исследованием, включающим культурологические и музыковедческие методы, что позволяет более полно раскрыть тему.

Longitudinal Breakdown Strength of Wet-mate Solid-Solid Interfaces at VLF and 50 Hz AC voltages
Authors: Ildstad Erling , Dale Roger , Kantar Emre 
Published: July 2022

The 50 Hz AC breakdown strength of dry interfaces is known to strongly depend upon the mechanical properties, contact pressure, roughness of the surfaces, and the type of lubricant used at the interface. This paper aims to experimentally examine how these factors affect the longitudinal AC breakdown strength of interfaces assembled in water, so-called wet interfaces. The main aim is to obtain data relevant to the design of power equipment operating at very low frequency (VLF) or DC voltages.Experiments were conducted using identical specimens made from 4mm thick plaques of PMMA and plane sections cut from XLPE cable insulation. The findings were discussed with respect to expected dimensions of interface voids and contact regions, considering tribology-based contact theory, including the impact of surface roughness, modulus of elasticity, and applied mechanical interface pressure.
The longitudinal 50 Hz AC breakdown strength values of wet samples were typically as low as 80 % of samples assembled in the air under dry conditions. In addition, the results verified previous findings that the AC breakdown strength strongly increases with reduced surface roughness, stiffness, and increased interface pressure. The breakdown values obtained during VLF breakdown testing were found to be 2 – 3 times higher than in the case of testing at 50 Hz AC voltages.

AbstractThe Florida Canyon Zn deposit in the Bongará Province of northern Peru consists of sulfide and nonsulfide mineralizations within dolomitized strata of the Triassic Chambará Formation, a member of the Triassic-Jurassic Pucará Group. The nonsulfide mineralization, which represents one third of the total resource, formed by supergene alteration of Mississippi Valley-type sulfide bodies. The nonsulfide assemblages occur in stratabound or fault-related, discordant zones that mimic the shapes of the former sulfide zones. Two nonsulfide facies can be distinguished: facies 1 – red zinc ores, which are characterized by smithsonite, or hemimorphite-dominant bodies that formed by direct replacement of primary sulfide assemblages, and facies 2 – white zinc ores, which are characterized by masses of colloform smithsonite formed by replacement of wall rock. The facies are distinct in bulk chemical composition and stable isotope geochemistry. Facies 1 shows high concentrations of Zn, Pb, Fe, Ge, Mn, and As, whereas facies 2 shows only high Zn and Cd concentrations. Enrichments in Ge, which have been reported in other Zn deposits of the Bongará Province, are associated with hemimorphite, Fe hydroxides, and remnant sphalerite in facies 1. The δ13C and δ18O signatures of smithsonite in both facies suggest that meteoric waters infiltrating the precursor sulfide bodies were affected by kinetic fractionation and originated from multiple sources at different altitude.
