Introduction. The article presents a technology of erecting of high-rise building's frame structures made of B60-B100 classes high-strength concretes. This technology includes a complex of processes and considers a number of special features, the most significant of which are connected with the specific character of high-strength concretes and concreting climatic conditions.Aim. To determine the main requirements for the technology of concreting and parameters of curing the monolithic structures of high-rise buildings made of B60-B100 classes high-strength concretes, including at winter periods, at the various stages of their erection.Methods and materials. Studies were carried out on the effect of hardening temperature variations from +5 to +50 °С on the hardening kinetics of B60, B80, and B100 classes concretes. Based on the 15-year experience of the “Moscow-City” construction, the mix proportions of high-strength concretes were optimized, as well as the main technological parameters of concreting and curing the frame structures located at an altitude of up to 370 m were analyzed and summarized.Results. The mix proportions of B60-B100 classes concretes of high-workability and self-compacting mixtures with a cement consumption of 350–480 kg/m3 was optimized using standard materials and MB-type organomineral modifiers. The performed study revealed a regularity between the strength and the temperature-temporal parameter of concrete curing, which is applicable for a preliminary assessment of strength characteristics in high-strength concrete structures on the basis of their temperature measurement results. A systematic approach to concrete curing and the maintenance of building structures as a whole with the vertical division of a high-rise building into four temperature zones led to a reducing the probability of thermal cracks appearance.Conclusions. According to the results of the study, the proposed complex of technological solutions concerning compositions and properties of concrete mixtures and concretes, the technology of concreting, as well as the methods of heating and curing the concrete of structures at the various stages of their erection ensures thermal resistance to cracks at the early stage of concrete hardening, as well as the high quality and assigned rates of construction.

Introduction. Reinforced concrete structures affected by various aggressive environments operate under off-center compression. Fiber-reinforced polymer (FRP) rebars replacing steel reinforcement in these structures are capable of increasing their durability and decreasing operating costs. However, the use of FRP rebars is limited by insufficient previous research into the methods of designing such constructions. The majority of international regulatory technical documents concerning the design of concrete structures reinforced with FRP rebars indicate the necessity of detailed studies into the stress-strain state of these structures under compression.Aim. To study the effect of longitude and shear reinforcement on load-bearing characteristic of stressed concrete samples reinforced with longitudinal glass fiber-reinforced polymer (GFRP) rebars.Materials and methods. The study was carried out using a concrete prism sample with different parameters of longitudinal and shear reinforcement. Five types of GFRP rebars differing in mechanical properties, as well as anchorage were considered. Shear reinforcement of the samples was performed with metal clamps at different pitches. The sample testing was fulfilled using centric compression with static load.Results. The strength values of compressed concrete samples reinforced with GFRP rebars were obtained. An increase of up to 19 % in the strength of compressed concrete samples reinforced with GFRP rebars was found in comparison with non-reinforced samples.Conclusions. The strength of compressed concrete elements increases when reinforced with glass fiber-reinforced polymer rebars. The degree of increase in the strength of such elements depends on the number of longitudinal reinforcements, as well as shear reinforcement pitch. The effect of the type of anchorage of GFRP rebars along with the values of its compression resistance on the strength of compressed concrete elements have not been established.

Published: August 2022

Introduction. With the introduction of a new national standard GOST 32703–2014 “Automobile roads of general use. Crushed stone and gravel from rocks. Technical requirements”, mining companies producing crushed stone from dense rocks faced the problem of ensuring the production output in compliance with two significantly different standards, both regulating the properties of crushed stone. The complexity of a balanced approach to production planning and stock reserve maintenance determines the need to assess the possibility of using crushed stone produced according to GOST 32703 when producing construction works, concrete mixes, and concrete for general civil construction.Aim: to define the prospects of using crushed stone produced according to GOST 32703 when producing concrete for general civil construction.Materials and methods. Crushed stone produced according to GOST 8267 and GOST 32703 from solid rocks of various origin—granite, gabbro-diabase, and dense limestone—was used as coarse aggregates for concrete production. Comparative tests of concrete mixes prepared from crushed stone from one deposit but classified in accordance with two different standards were performed. The main quality parameters of concrete mixes were determined by testing methods according to GOST 10181, while the mechanic al and physical properties of concrete mixes were determined by testing methods according to GOST 10180.Results. The study showed a certain compatibility of the quality properties of concrete mixes and the mechanical and physical properties of concrete filled with crushed stone, which is classified according to different standards but having the same content of lamellar and needle-shaped particles.Conclusions. Recommendations are formulated on the prospects of using crushed stone produced according to GOST 32703 when producing concrete for general civil construction. The key issues concerned with simultaneous application of two different standards are indicated.

Published: August 2022

In 2007, the European Commission initiated the Eel Recovery Plan (Council Regulation No. 1100/2007) to try to bring the European eel stocks back to more sustainable adult levels and the return of the glass eel. Each EU Member State is required to develop a national eel management plan. These plans aim to achieve a return of silver eels to the spawning population equal to or greater than 40% of the potential biomass that could be obtained in the absence of anthropogenic disturbances related to fishing, water quality or barriers to migration. The advantage of this approach is that it offers a standard basis and allows for the integration of stock status data between EU and non-EU countries.
The purpose of this Plan was to determine for the Vistula Lagoon within the territory of the Kaliningrad region of the Russian Federation:
1. Management objectives based on an assessment of the potential stock of the silver eel in the absence of anthropogenic mortality and high (before 1980) recruitment levels.
2. The current level of the stock of silver eel in relation to the planned indicator (ie assessment of compliance with the planned indicator).
3. Control actions necessary to achieve or maintain this compliance.
4. A set of data needed to support the steps 1-3 above and to demonstrate whether compliance will be achieved in the future, i.e. that the actions defined in the management plan will lead to the recovery of the eel population.

Published: August 2022

The technology being developed for the production of a feed mixture based on the biomass of a cultivated worm is aimed at improving factory feeds by adding an additional volume of protein, thereby increasing the nutritional value of the feed, eliminating the need to buy a specific feed of greater nutritional value, providing the opportunity to supplement feeds less saturated with protein components. Also, the technology being developed is aimed at partial or complete replacement of currently known protein feed components (such as soy meal, meat and bone meal and fish meal).
In the course of the study, a trial production of a protein feed component was carried out, according to the methodologies described in the work, in order to test the proposed technology in practice.

Published: August 2022

Strabon’un, içinden Iris’in aktığı ve verimli bir ova olarak tanımladığı Dazimonitis bugünkü Kazova’nın Antik Çağ’daki adıydı. Dazimonitis Hellenistik Dönem’in başlarında Pontos Krallığı’nın, bu dönemin sonlarına doğru ise Roma’nın sınırları içerisine dâhil edilse de belirtilen bu tarihi süreçlerde yarı-özerk statüye sahip Komana tapınak devletinin mülküydü. Ancak Dazimonitis’in, Pontos Krallığı ile Roma arasında yaşanan mücadelede bir rolü olduğu da bilinmektedir. Bu bağlamda III. Mithradates-Roma Savaşı sırasında, VI. Mithradates tarafından ovanın sunmuş olduğu erzak tedariki imkânı ortadan kaldırılarak Roma ordusu yıpratılmaya çalışılmıştı. Dazimonitis’in sadece bu amaca hizmet etmediğini, Kazova’nın güneyindeki dağlık kesimde yer alan ve Pazar ilçesini Artova üzerinden Sivas iline bağlayan stratejik bir yol üzerindeki bir tepede konuşlandırılmış ve şimdiye kadar herhangi bir bilimsel çalışmanın konusu olmamış olan Dereköy Kalesi kanıtlamaktadır.
Kazova’nın üzerine kurulu olan Pazar ilçesinde 2019 yılında gerçekleştirdiğimiz arkeolojik yüzey araştırması sırasında inceleme fırsatını bulduğumuz Dereköy’de bulunan ve köyün adıyla anılan kale, basamaklı bir tünele sahip olmasıyla dikkatleri üzerine çekmektedir. Böylece Dazimonitis’te yeni bir Pontos Krallığı Kalesi keşfedilerek bu dönemdeki savunma sisteminin atar damarları olan kaleler ağının şimdiye kadar bilinmeyen bir parçası bölge tarihine kazandırılmıştır. Bu çalışmayla söz konusu kalenin Hellenistik Dönem’deki yeri, önemi ve işlevi açığa çıkartılmaya çalışılacaktır.
Magnetized Oscillatory Double-diffusive Convection
Authors: Sanghi A. , Fraser A. E. , Tian E. W. , Garaud P. 
Published: August 2022

AbstractWe study the properties of oscillatory double-diffusive convection (ODDC) in the presence of a uniform vertical background magnetic field. ODDC takes place in stellar regions that are unstable according to the Schwarzschild criterion and stable according to the Ledoux criterion (sometimes called semiconvective regions), which are often predicted to reside just outside the core of intermediate-mass main-sequence stars. Previous hydrodynamic studies of ODDC have shown that the basic instability saturates into a state of weak wave-like convection, but that a secondary instability can sometimes transform it into a state of layered convection, where layers then rapidly merge and grow until the entire region is fully convective. We find that magnetized ODDC has very similar properties overall, with some important quantitative differences. A linear stability analysis reveals that the fastest-growing modes are unaffected by the field, but that other modes are. Numerically, the magnetic field is seen to influence the saturation of the basic instability, overall reducing the turbulent fluxes of temperature and composition. This in turn affects layer formation, usually delaying it, and occasionally suppressing it entirely for sufficiently strong fields. Further work will be needed, however, to determine the field strength above which layer formation is actually suppressed in stars. Potential observational implications are briefly discussed.
Synchrotron Self-Compton Afterglow Closure Relations and Fermi-LAT-detected Gamma-Ray Bursts

Published: August 2022

Abstract
The Fermi Large Area Telescope (Fermi-LAT) Collaboration reported the Second Gamma-ray Burst Catalog (2FLGC), which comprises a subset of 29 bursts with photon energies above 10 GeV. Although the standard synchrotron forward-shock model has successfully explained the gamma-ray burst (GRB) afterglow observations, energetic photons higher than 10 GeV from these transient events can hardly be described in this scenario. We present the closure relations (CRs) of the synchrotron self-Compton (SSC) afterglow model in the adiabatic and radiative scenario, and when the central engine injects continuous energy into the blast wave to study the evolution of the spectral and temporal indexes of those bursts reported in 2FLGC. We consider the SSC afterglow model evolving in stellar-wind and the interstellar medium (ISM), and the CRs as a function of the radiative parameter, the energy injection index, and the electron spectral index for 1 < p < 2 and 2 ≤ p. We select all GRBs that have been modeled with both a simple or a broken power law in the 2FLGC. We found that the CRs of the SSC model can satisfy a significant fraction of the burst that cannot be interpreted in the synchrotron scenario, even though those that require an intermediate density profile (e.g., GRB 130427A) or an atypical fraction of total energy given to amplify the magnetic field (ε

B
). The value of this parameter in the SSC model ranges (ε

B
≈ 10−5 − 10−4) when the cooling spectral break corresponds to the Fermi-LAT band for typical values of GRB afterglow. The analysis shows that the ISM is preferred for the scenario without energy injection and the stellar-wind medium for an energy injection scenario.

We present the third discovery from the COol Companions ON Ultrawide orbiTS (COCONUTS) program, the COCONUTS-3 system, composed of the young M5 primary star UCAC4 374−046899 and the very red L6 dwarf WISEA J081322.19−152203.2. These two objects have a projected separation of

⊙, and we estimate its age as 100 Myr to 1 Gyr based on its stellar activity (via Hα and X-ray emission), kinematics, and spectrophotometric properties. We derive its bulk metallicity as 0.21 ± 0.07 dex using empirical calibrations established by older and higher-gravity M dwarfs and find that this [Fe/H] could be slightly underestimated according to PHOENIX models given COCONUTS-3A’s younger age. The companion, COCONUTS-3B, has a near-infrared spectral type of L6 ± 1 int-g, and we infer physical properties of T

We construct cloudy atmospheric model spectra at the evolution-based physical parameters and compare them to COCONUTS-3B’s spectrophotometry. We find that this companion possesses ample condensate clouds in its photosphere (f
sed = 1) with the data–model discrepancies likely due to the models using an older version of the opacity database. Compared to field-age L6 dwarfs, COCONUTS-3B has fainter absolute magnitudes and a 120 K cooler T

COCONUTS-3 likely formed in the same fashion as stellar binaries given the companion-to-host mass ratio of 0.3 and represents a valuable benchmark to quantify the systematics of substellar model atmospheres.
The Dark Matter Halo of M54
Authors: Carlberg Raymond G. , Grillmair Carl J. 
Published: August 2022

Abstract
M54 is a prototype for a globular cluster embedded in a dark matter halo. Gaia Early Data Release 3 photometry and proper motions separate the old, metal-poor stars from the more metal-rich and younger dwarf galaxy stars. The metal-poor stars dominate the inner 50 pc, with a velocity dispersion profile that declines to a minimum around 30 pc then rises back to nearly the central velocity dispersion, as expected for a globular cluster at the center of a cold dark matter (CDM) cosmology dark matter halo. The Jeans equation mass analysis of the three separate stellar populations gives consistent masses that rise approximately linearly with radius to 1 kpc. These data are compatible with an infalling CDM dark matter halo reduced to ≃3 × 108
M
⊙ at the 50 kpc apocenter 2.3 Gyr ago, with a central globular cluster surrounded by the remnant of a dwarf galaxy. Tides gradually remove material beyond 1 kpc but have little effect on the stars and dark matter within 300 pc of the center. M54 appears to be a “transitional” system between globular clusters with and without local dark halos whose evolution within the galaxy depends on the time of accretion and orbital pericenter.
Component of Energy Flow from Supercritical Accretion Disks Around Rotating Stellar Mass Black Holes

Published: August 2022

Abstract
By performing two-dimensional axisymmetric general relativistic radiation magnetohydrodynamics simulations with spin parameter a* varying from −0.9 to 0.9, we investigate the dependence on the black hole spin of the energy flow from a supercritical accretion disk around a stellar mass black hole. It is found that optically and geometrically thick disks form near the equatorial plane, and a part of the disk matter is launched from the disk surface in all models. The gas ejection is mainly driven by the radiative force, but magnetic force cannot be neglected when ∣a*∣ is large. The energy outflow efficiency (total luminosity normalized by

Edd is the Eddington luminosity). Furthermore, although the energy is mainly released by radiation when a* ∼ 0, the Poynting power increases with ∣a*∣ and exceeds the radiative luminosity for models with a* ≥ 0.5 and a* ≤ −0.7. The faster the black hole rotates, the higher the power ratio of the kinetic luminosity to the isotropic luminosity tends to be. This implies that objects with a high (low) power ratio may have rapidly (slowly) rotating black holes. Among ultraluminous X-ray sources, IC342 X-1, is a candidate with a rapidly rotating black hole.
