Evolution of The Handball Talent Care System in Hungary - pilot study
Authors: Juhász Bernadett , Bácsné Bába Éva 
Published: June 2020

Development of talents care systems plays an important role in handball today. The goal of the Hungarian Handball Association is to ensure that all children of the same age receive the same training throughout the country. The Association recently introduced a standard feed-back education system. The aim of this research was to demonstrate the evolution of the talent care system, especially the innovations introduced by the Association.
The research method was interviewing handball experts. Five experts answered our questions, former elite players, currently coaches. Based on their responses, it was possible to compare the old and the current status of the training programmes. We may conclude, that the structure of handball training has significantly developed both technically and tactically. Professionals agree, that there are a number of changes have occurred in the theory and methodology of handball. The newly introduced regional, electronic control system – described in the Age Handbook were considered to be useful by the interviewees. According to the results of our pilot study, the new unified educational training system may result in a more successful international presence in the long term.
Examination of the Relationship Between Physical Activity and Cognitive Skills
Authors: Makra Gabriella , Balogh László 
Published: June 2020

Introduction: Examining physical activity and cognitive function has become a popular topic of research since the quality of these two components influences our quality of life and performance. It is very important for both sexes, all ages and life situations.
Objective: Determining a type of physical activity (PA) that has an effect on both cognitive functions (CF) and motor skills and performance. Clarifying or promoting measurement methods, or developing new methods that meet current standards and objectives. The results may be used to help to impove performance in all areas.
Method: Primary purpose of our study was to conduct a review, in order to summarize the relevant literature on the following topics: sex, age, fitness level, possible illness.
Conclusions: We found a significant relationship between cognitive functions and physical activity, which can be transposition in a proper way, both in terms of living standards and performance. On the other hand, there are a lack of uniform, accurate measurement methods. Thhere is a need for specific physical activity routines that specifically improve the level of cognitive function, even at an older age.

Authors: Dara Lilla Csenge , Bácsné Bába Éva 
Published: June 2020

The main focus of our research was the U16 age group since it is one of the most significant in terms of the young athlete’s future - probably professional - career. It was very helpful in research that this age group was a priority in the Basketball Academy of Debrecen’s program and they were competing in an international basketball league, in the European Youth Basketball League (EYBL). Thanks to the EYBL tournaments we have got a chance to analyze this youth category completely. For primer research we have chosen three teams, two Hungarian, and one Italian, to get an impression why is so important to play basketball at the international level in this age. We have made interviews with the coaches, organizers and the manager of the league to have an international comparison of this age group.

Исследованы возможные предельно допустимые состояния слоистых полиметаллических стержней постоянного сечения при воздействии произвольно расположенных в пролете сосредоточенных нагрузок. Рассматриваются три возможных предельных состояния: первое (предельно упругое), второе (состояние предразрушения) и третье (состояние разрушения). Сформулированы условия их реализации, определены соответствующие уровни предельных нагрузок и намечены пути управления параметрами нагружающих устройств для обеспечения благоприятных процессов деформирования.
Possible maximum permissible states of layered polymetallic rods of constant cross section under the influence of concentrated loads arbitrarily located in the span are studied. Three possible limiting states are considered: the first (extremely elastic), the second (pre-fracture state) and the third (fracture state). The conditions for their implementation are formulated, the corresponding levels of ultimate loads are determined, and ways to control the parameters of loading devices to ensure favorable deformation processes are outlined.

Abstract
We infer the number of planets per star as a function of orbital period and
planet size using Kepler archival data products with updated stellar properties
from the Gaia Data Release 2. Using hierarchical Bayesian modeling and
Hamiltonian Monte Carlo, we incorporate planet radius uncertainties into an
inhomogeneous Poisson point process model. We demonstrate that this model
captures the general features of the outcome of the planet formation and
evolution around GK stars and provides an infrastructure to use the Kepler
results to constrain analytic planet distribution models. We report an increased
mean and variance in the marginal posterior distributions for the number of
planets per GK star when including planet radius measurement uncertainties. We
estimate the number of planets per GK star between 0.75 and 2.5
R
⊕ and with orbital periods of
50–300 days to have a 68% credible interval of 0.49–0.77 and
a posterior mean of 0.63. This posterior has a smaller mean and a larger
variance than the occurrence rate calculated in this work and in Burke et al.
for the same parameter space using the
Q1−Q16 (previous Kepler planet
candidate and stellar catalog). We attribute the smaller mean to many of the
instrumental false positives at longer orbital periods being removed from the
DR25 catalog. We find that the accuracy and precision of our hierarchical
Bayesian model posterior distributions are less sensitive to the total number of
planets in the sample, and more so for the characteristics of the catalog
completeness and reliability and the span of the planet parameter space.
Coupled Thermal and Compositional Evolution of Photoevaporating Planet Envelopes
Authors: Malsky Isaac , Rogers Leslie A. 
Published: June 2020

Abstract
Photoevaporative mass loss sculpts the atmospheric evolution of tightly orbiting sub-Neptune-mass exoplanets. To date, models of the mass loss from warm Neptunes have assumed that the atmospheric abundances remain constant throughout the planet’s evolution. However, the cumulative effects of billions of years of escape modulated by diffusive separation and preferential loss of hydrogen can lead to planetary envelopes that are enhanced in helium and metals relative to hydrogen. We have performed the first self-consistent calculations of the coupled thermal, mass-loss, and compositional evolution of hydrogen–helium envelopes surrounding sub-Neptune-mass planets. We extended the Modules for Experiments in Stellar Astrophysics stellar evolution code to model the evolving envelope abundances of photoevaporating planets. We demonstrate that H–He fractionation can lead to planetary envelopes that are significantly enriched in helium and metals compared to their initial primordial compositions. A subset of our model planets—having R
p ≲ 3.00 R
⊕, initial f
env < 0.5%, and irradiation flux ∼101–103 times that of Earth—obtain final helium mass fractions in excess of Y = 0.40 after several billion years of mass loss. GJ 436b, the planet that originally inspired Hu et al. to propose the formation of helium-enhanced planetary atmospheres, requires a primordial envelope that is too massive to become helium enhanced. Planets with envelope helium fractions of Y = 0.40 have radii that are between 0.5% and 10% smaller (depending on their mass, irradiation flux, and envelope mass fraction) than similar planets with solar composition (Y = 0.24) envelopes. The results of preferential loss of hydrogen may have observable consequences for the M
p − R
p relations and atmospheric spectra of sub-Neptune populations.

Abstract
We present an IGM H i tomographic map in a survey volume of

(cMpc3) centered at MAMMOTH-1 nebula and three neighboring quasars at z = 2.3. The MAMMOTH-1 nebula is an enormous Lyα nebula (ELAN), hosted by a type-II quasar dubbed MAMMOTH1-QSO, that extends over

cMpc with no clear physical origin. Here we investigate the H i-gas distribution around MAMMOTH1-QSO with the ELAN and three neighboring type-I quasars, making the IGM H i tomographic map with a spatial resolution of 2.6 h
−1 cMpc. Our H i tomographic map is reconstructed with H i Lyα forest absorption of bright background objects at z = 2.4–2.9: one eBOSS quasar and 16 Keck/LRIS galaxy spectra. We estimate the radial profile of H i overdensity for MAMMOTH1-QSO, and find that MAMMOTH1-QSO resides in a volume with fairly weak H i absorption. This suggests that MAMMOTH1-QSO may have a proximity zone where quasar illuminates and photoionizes the surrounding H i gas and suppresses H i absorption, and that the ELAN is probably a photoionized cloud embedded in the cosmic web. The H i radial profile of MAMMOTH1-QSO is very similar to those of three neighboring type-I quasars at z = 2.3, which is compatible with the AGN unification model. We compare the distributions of the H i absorption and star-forming galaxies in our survey volume, and identify a spatial offset between density peaks of star-forming galaxies and H i gas. This segregation may suggest anisotropic UV background radiation created by star-forming galaxy density fluctuations.

Abstract
The radio source 3C 264, hosted by the giant elliptical galaxy NGC 3862, was observed with the Very Energetic Radiation Imaging Telescope Array System (VERITAS) between 2017 February and 2019 May. These deep observations resulted in the discovery of very high energy (VHE; E > 100 GeV) γ-ray emission from this active galaxy. An analysis of ∼57 hr of quality-selected live time yields a detection at the position of the source, corresponding to a statistical significance of 7.8 standard deviations above background. The observed VHE flux is variable on monthly timescales, with an elevated flux seen in 2018 observations. The VHE emission during this elevated state is well characterized by a power-law spectrum with a photon index Γ = 2.20 ± 0.27 and flux F(>315 GeV) = (

cm−2 s−1, or approximately 0.7% of the Crab Nebula flux above the same threshold. 3C 264 (z = 0.0217) is the most distant radio galaxy detected at VHE, and the elevated state is thought to be similar to that of the famously outbursting jet in M87. Consequently, extensive contemporaneous multiwavelength data were acquired in 2018 at the time of the VHE high state. An analysis of these data, including Very Long Baseline Array, Very Large Array, Hubble Space Telescope, Chandra, and Swift observations in addition to the VERITAS data, is presented, along with a discussion of the resulting spectral energy distribution.

Abstract
The position of galaxies on the stellar mass, star formation rate (SFR) plane with respect to the star-forming main sequence at each redshift is a convenient way to infer where the galaxy is in its evolution compared to the rest of the population. We use Hubble Space Telescope high-resolution images in the GOODS-S field from the the Cosmic Assembly Near-IR Deep Extragalactic Legacy Survey (CANDELS) and fit multiwavelength lights in resolution elements of galaxies with stellar population synthesis models. We then construct resolved kpc-scale stellar mass, SFR surface density curves for galaxies at z ∼ 1. Fitting these resolved main sequence curves with Schechter functions, we parameterize and explain the multiwavelength structure of galaxies with three variables: ϕ*, α, and M*. For quenched galaxies below the main sequence, we find an average high-mass slope (α) of the resolved main sequence curves to be ∼−0.4. The scatter of this slope is higher among the lower mass star-forming galaxies and those above the main sequence compared to quenched galaxies, due to lack of an evolved bulge. Our findings agree well with an inside-out quenching of star formation. We find that the knee of the Schechter fits (M*) for galaxies below the main sequence occurs at lower stellar mass surface densities compared to star-forming galaxies, which hints at how far quenching has proceeded outward.
L’histoire populaire : label éditorial ou nouvelle forme d’écriture du social ?
Authors: Ruiz Émilien 
Published: June 2020

S’il fallut plus de deux décennies pour que l’ouvrage d’Howard Zinn, People’s History of the United States (Harper Collins, 1980), fût traduit en français sous le titre Une histoire populaire des États-Unis (Agone, 2002), les années 2010 ont vu se multiplier les histoires dites « populaires ». Il s’agit, pour partie, de traductions de people’s history of… qui offrent ainsi au lectorat francophone des histoires populaires de l’humanité, des sciences ou encore du sport. Mais depuis trois ou quatre ans, l’historiographie française s’est aussi enrichie de multiples « histoires populaires », qu’il s’agisse, par exemple, de Nantes, du football ou, bien entendu, de la France avec les parutions successives, en 2016 et 2018, des sommes de Michelle Zancarini-Fournel et Gérard Noiriel. Cette multiplication interroge : relève-t-elle d’une simple labellisation éditoriale ? Le succès commercial des travaux d’Howard Zinn et de ses déclinaisons (en BD, documentaires, versions abrégées, pour enfants, etc.) aurait ainsi conduit des éditeurs à tenter, sinon de reproduire le phénomène, de profiter de « la marque » que représente le titre. À moins que la lecture des ouvrages ainsi publiés nous conduise à observer l’émergence d’une nouvelle forme d’écriture du social ? Fruit de renouvellements historiographiques conduisant à renoncer à des formulations plus classiques, au premier rang desquelles « une histoire sociale de… ».
Protective role of a melon superoxide dismutase combined with gliadin (GliSODin) on the status of lipid peroxidation and antioxidant defense against azoxymethane-induced experimental colon carcinogenesis
Authors: Baba-Ahmed Fedia , Guedri Kamilia , Trea Fouzia , Ouali Kheireddine 
Published: June 2020

Background:
Azoxymethane (AOM) is a potent carcinogenic agent commonly used to induce colon cancer in rats and mice, with the cytotoxicity of AOM mediated by oxidative stress.

Aim of Study:
This study investigated the protective effect of a natural antioxidant (GliSODin) against AOM-induced oxidative stress and carcinogenesis in rat colon.

Methods:
Twenty male Wistar rats were randomly divided into four groups (five rats/group). The control group was fed a basal diet. AOM-treated group (AOM) was fed a basal diet and received intraperitoneal injections of AOM for 2 weeks at a dose of 15 mg/kg. The GliSODin treatment group (superoxide dismutase [SOD]) received oral supplementation of GliSODin (300 mg/kg) for 3 months, and the fourth combined group received AOM and GliSODin (AOM + SOD). All animals were continuously fed ad libitum until the age of 16 weeks when all rats were sacrificed. The colon tissues were examined microscopically for pathological changes and aberrant crypt foci (ACF) development, oxidant status (lipid peroxidation-LPO), and enzyme antioxidant system (glutathione [GSH], GSH-S-transferase, catalase, and SOD).

Results:
Our results showed that AOM induced ACF development and oxidative stress (GSH depletion and lipid peroxidation) in rat colonic cells. The concomitant treatment of AOM with GliSODin significantly ameliorated the cytotoxic effects of AOM.

Conclusion:
The results of this study provide in vivo evidence that GliSODin reduced the AOM-induced colon cancer in rats, through their potent antioxidant activities.
