Authors:   Technical University of Cluj-Napoca, Hotea Vasile , Juhasz Jozsef ,   Technical University of Cluj Napoca
Published: June 2021

Pastes of granulated blast furnace slag and zeolitic tuffat different mass ratios were activated with alkali solution (sodium silicate) at lower alkalinity with modulus Ms= %SiO2 /%Na2O = 2 . The heavy metals contained in slag are immobilized into geopolymer matrix of composite material, so obtained and thus significantly reduces the risk of environment contamination. Granulated lead furnace slag, zeolitic tuff, sodium hydroxide and sodium silicate were used as starting materials. Binder of 50% slag developed the highest among all slag based geopolymeric pastes whose compressive strength are 42 MPa. As a result, the cement containing 50% slag that is synthesized at curing (600 C for 12 h), exhibited higher mechanical strength and SEM observation shows that it is possible to have localized of (C-S-H) geopolymeric gel. Pastes of granulated blast furnace slag (GBFS) and zeolitic tuff(BZ) in mixture developed stable microstructures with high compressive strengths, and the toxic metals (Pb, Zn, Cd) from slag were locked into the geopolymeric matrix.

COMPARATIVE ANALYSES OF PREPOSITONS IN JAPANESE AND UZBEK LANGUAGES
Authors:   Teacher, Uzbekistan State World Languages University, Malikova Sitorabonu Farxodovna
Published: June 2021

In linguistics, the comparison of languages has always been in the center of attention. Although it is recognized by scholars that Japanese and Uzbek belong to the same language family, the Altaic language family, grammatical phenomena in both languages are not the same. While both languages have similarities, they also have differences. Comparing languages belonging to the same language family involves studying the phenomena that occur in that language. The category of agreement is widely observed in both languages, but there are some agreements between Japanese agreement agreements, which are given with one agreement in Uzbek, and the scope of application is narrow. The category of consonants is widely observed in both languages, but there are some consonants among the Japanese suffixes, which are given with one consonant in Uzbek, and the scope of application is also narrow. This article provides a comparative analysis of the Uzbek suffix of the accusative case and the differences between them
Gender projections in the novel Soul in A Mask by N. V. Nedobrovo
Authors: Kaplun Marianna V.
Published: June 2021

The prose novel by N. V. Nedobrovo Soul in A Mask, written in 1914, incorporates basic ideas of the writer’s work and continues development of gender (feminine) discourse of the modern era. To a large extent, the search for a “soul in a mask”, the ability to express a lyrical “I”, coupled with the theatricality of being, the need for a social masquerade, are characteristic of the majority of modernist works. The theme of masks is equally present in the lyrics of symbolism and close to Nedobrovo acmeism (for example, in the work of A. A. Akhmatova, Nedobrovo’s closest friend). The masquerade performs two functions in the novel — plot-forming and philosophical. Having made the center of the story of the reflecting heroine Olga, Nedobrovo displays a number of male characters, a collision which meant to reveal the title female character. Male / female opposition (masculinity / femininity) informs the main conflict of the novel, related to the inability of an intelligent woman of expressing herself in a male society without wearing a mask. The paper shows that the mask serves as a kind of gender projection and represents an attempt to overcome the social masquerade, which is always associated with an identity crisis. Mask, as applied to the heroine and her ready-made social mask gives an opposite effect, only emphasizing the gender difference and, accordingly, leading to the disclosure of the heroine’s femininity. Based on this, “female issue” raised in the story is resolved in compliance with patriarchal ideas of the conservative gender discourse of the turn of the century.

Published: June 2021

The present paper explores the history of one of the Tver Kremlin cemeteries first surveyed archaeologically in 1998 (figure 1). Based on the analyses of the material gained and its dating the authors indicate the period of the studied part of necropolis functioning as the second quarter of the 16th – the border of the 16–17th centuries (figures 2–5). The cemetery existed by the wooden church which was destroyed probably in the period of “the Time of Troubles” in the early 17th century. The church stood in the western part of the Tver Kremlin, 200 meters to the west of central ensemble of stone temples including the Cathedral of Transfiguration of Our Saviour as well as constructions of Prince’s Yard and the Bishop’s one. The consecration of the necropolis’ church has been determined probably as “the Church of Life-giving Trinity over the Bishop’s Yard” [6, р. 296]. Authors came to the conclusion on the basis of studying several written and archaeological sources.
The issue of relationship of grace and freedom in Berdyaev`s ethics
Authors: Zapeka Oksana A.
Published: June 2021

Berdyaev distinguishes between divine and human freedom. He considers the issue of relationship of God`s and man`s freedom to be central for ethics. While in western theology the issue of correspondence of grace and freedom appears mostly as a human will`s problem, the eastern tradition looks at the freedom of man and divine grace as an organic unity, yet acknowledges exclusively the freedom, created and granted by God. Eastern teachings, just as the western ones, do not address the freedom, preceding the Genesis. Orthodoxy`s advantage, according to N. A. Berdyaev, is in its lesser, comparing to Catholicism and Protestantism, extent of rationalizing, which to him constituted its greater degree of freedom. Without any doubt some of Berdyaev`s ideas are out of keeping with traditional Orthodoxy, most notably starting with his doctrine of Ungrund (divine Nothingness), giving way to manifestation of God-Creator and Freedom. Unlike traditional theology which associates origination of Evil with Freedom, God`s gift to a man Berdyaev believes that man belongs to Freedom as much as to God. Berdyaev`s presentation of relationship of freedom and grace, divine and human freedom as a central for the issue of Freedom is attributed to his striving to justify human freedom and establishing it in terms of its inherently human source.

It offers more advantages in terms of seakeeping performances, particularly on the application of a fishing vessel. However, thus far, the conventional design of fishing vessels is not favorable to ensure the safety of a vessel sailing in a rough sea. In conjunction with such issues, we discuss a trimaran fishing vessel design based on the seakeeping criterion to evaluate the dynamic stability, ship motion RAOs, and ship resistances at the initial design stages using linear strip theory. The intact stabilities are calculated to complement the seakeeping results. The analytical method based on the slender body method is used to evaluate the steady wave resistances. The results of heave, pitch, roll motions, and the ship resistances are discussed. At the zero speed and forward speed, the trimaran shows a favorable motion amplitude, although in forward speeds at the case of head seas there is no significant difference. The trimaran presents a favorable steady-resistance up to the ship speed of Fn=0.27, and it becomes deteriorating than the monohull at higher ship speeds. However, the added wave resistances of the wavelength range 1.0 – 3.0 shows significant added resistances at Fn=0.25 and Fn=0.35, respectively. The results of this study present promising seakeeping and resistance characteristics of the trimaran hull form. The trimaran hull form ensures the safety, reliability, and operation efficiency of ships sailing in broader ranges of violent-sea environment.
Numerical Solutions of Hybrid Nanofluids Flow Via Free Convection Over a Solid Sphere
Authors: Swalmeh Mohammed Zaki
Published: June 2021

The purpose of the existing study is to examine how heat transfer enables consolidated by variations in the basic advantages of fluids in the existence of free convection with the assistance of suspended hybrid nanofluids. Iron-graphene oxide suspended in water as a hybrid nanofluid flow on a solid sphere is also considered in this work. The partial differential equations are gotten, for this problem, by transforming the mathematical governing equations using similarity equations (stream function). These partial differential equations are solved numerically by Keller-Box method and programmed by MATLAB program. the acquired numerical results are in excellent agreement with the preceding literature results. Graphical results of the influence of the hybrid nanofluid parameters on some physical quantities regarded to examine the behavior of hybrid nanofluid flow were attained, and they proved that hybrid nanofluid flow represents a more essential role in the operation of heat transfer than a regular nanofluid flow.

Optical and infrared spectroscopy are presented for the classical nova V3666 Ophiuchi (Nova Ophiuchi 2018 No.3) from 11 months after its outburst. At that epoch, V3666 Oph displayed an [Fe x] λ0.6375 emission line stronger than Hα and nearly a factor of 3 larger, relative to Hα, than in any nova observed previously. The [Fe x] feature, with an equivalent width exceeding 1300 Å, was enormously strong relative to the continuum emission as well. V3666 Oph also reached a state of high excitation for an Fe ii type nova, displaying coronal lines of [Fe xi], [S ix], and [Ar x], and permitted features that can be identified with the C vi (8–7), (9–8), and (10–9) transitions. In addition to [Fe x] and [Fe xi], V3666 Oph also displayed bright lines of [Fe vii], indicating that the prominent iron features were not confined to a single or narrow range of ionization states. Modeling the emission line spectrum of V3666 Oph with the photoionization code Cloudy indicated that the bulk of the emission line gas was matter-bounded, severely reducing the amount of low ionization gas and resulting in coronal lines that were very strong in comparison to lines such as H i and He i, and the familiar low excitation forbidden lines of nitrogen and oxygen. Such matter-bounded regions are observationally rare in novae since they are both faint and short-lived, offering a plausible explanation for why [Fe x] λ0.6375 had not be seen at this strength previously.

We present the analyses of two microlensing events, OGLE-2018-BLG-0567 and OGLE-2018-BLG-0962. In both events, the short-lasting anomalies were densely and continuously covered by two high-cadence surveys. The light-curve modeling indicates that the anomalies are generated by source crossings over the planetary caustics induced by planetary companions to the hosts. The estimated planet/host separation (scaled to the angular Einstein radius θ
E) and mass ratio are (s, q × 103) = (1.81 ± 0.02, 1.24 ± 0.07) and (s, q × 103) = (1.25 ± 0.03, 2.38 ± 0.08), respectively. From Bayesian analyses, we estimate the host and planet masses as

The two events prove the capability of current high-cadence surveys for finding planets through the planetary-caustic channel. We find that most published planetary-caustic planets are found in Hollywood events in which the source size strongly contributes to the anomaly cross-section relative to the size of the caustic.

We present a novel, iterative method using an empirical Bayesian approach for modeling the limb-darkened WASP-121b transit from the TESS light curve. Our method is motivated by the need to improve R

With the nonlinear LD law, the method has all the advantages of not needing atmospheric models but does not converge. The iterative method gives a different R

This paper details speckle observations of binary stars taken at the Lowell Discovery Telescope, the WIYN telescope, and the Gemini telescopes between 2016 January and 2019 September. The observations taken at Gemini and Lowell were done with the Differential Speckle Survey Instrument (DSSI), and those done at WIYN were taken with the successor instrument to DSSI at that site, the NN-EXPLORE Exoplanet Star and Speckle Imager (NESSI). In total, we present 378 observations of 178 systems, and we show that the uncertainty in the measurement precision for the combined data set is ∼2 mas in separation, ∼1°–2° in position angle depending on the separation, and ∼0.1 mag in magnitude difference. Together with data already in the literature, these new results permit 25 visual orbits and one spectroscopic-visual orbit to be calculated for the first time. In the case of the spectroscopic-visual analysis, which is done on the ternary star HD 173093, we calculate masses with a precision of better than 1% for all three stars in that system. Twenty-one of the visual orbits calculated have a K dwarf as the primary star; we add these to the known orbits of K-dwarf primary stars and discuss the basic orbital properties of these stars at this stage. Although incomplete, the data that exist so far indicate that binaries with K-dwarf primaries tend not to have low-eccentricity orbits at separations of one to a few tens of astronomical units, that is, on solar system scales.
Thermal Desorption of Astrophysically Relevant Ice Mixtures of Acetaldehyde and Acetonitrile from Olivine Dust*

Millimeter and centimeter observations are discovering an increasing number of interstellar complex organic molecules (iCOMs) in a large variety of star-forming sites, from the earliest stages of star formation to protoplanetary disks and in comets. In this context it is pivotal to understand how the solid-phase interactions between iCOMs and grain surfaces influence the thermal desorption process and, therefore, the presence of molecular species in the gas phase. In the laboratory, it is possible to simulate the thermal desorption process, deriving important parameters such as the desorption temperatures and energies. We report new laboratory results on temperature-programmed desorption from olivine dust of astrophysical relevant ice mixtures of water, acetonitrile, and acetaldehyde. We found that in the presence of grains, only a fraction of acetaldehyde and acetonitrile desorb at about 100 K and 120 K, respectively, while 40% of the molecules are retained by fluffy grains of the order of 100 μm up to temperatures of 190–210 K. In contrast with the typical assumption that all molecules are desorbed in regions with temperatures higher than 100 K, this result implies that about 40% of the molecules can survive on the grains enabling the delivery of volatiles toward regions with temperatures as high as 200 K and shifting inwards the position of the snow lines in protoplanetary disks. These studies offer a necessary support to interpret observational data and may help our understanding of iCOM formation, providing an estimate of the fraction of molecules released at various temperatures.
