Published: October 2021

Abstract
Two kinds of phase stabilization mechanism are discussed and compared: the first is characteristic of the formation of bulk amorphous alloys, in which the high supercooling ability of multicomponent liquids is responsible for the glassy phase stabilization. Here the hindered nucleation of crystalline phases is the center phenomenon. The origin of this hindering is the slowing atomic mobility in the supercooling melt. In contrast the melt supercooling is negligible during the high entropy alloy formation. It is believed that stability of the crystalline single fcc phase is the consequence of the characteristic of high configurational entropy at high temperatures. However, the significance of this entropy-dominated stabilization is overestimated in several references. It has been concluded that transition metal contraction (arising from the d electron participation in the overall bonding state) does also contribute to the high temperature stability of fcc single phase in the high entropy alloys.

Online learning is one of the new policies in the education sector due to the global pandemic, namely COVID-19. This online learning policy is expected to continue to support the achievement of educational goals. Effectiveness in learning is often measured as a standard for achieving educational goals. Google classroom as a digital-based education platform is considered capable of being a learning link between teachers and students. The implementation of this research is to determine the effectiveness of online teaching and learning activities using Google Classroom at SMA Negeri 1, SMA Negeri 3, SMA Negeri 7 and SMA Negeri 8. This research is quantitative descriptive. The population used in this study were students in grades X, XI, and XII and high school teachers in the city of Samarinda. Data retrieval was carried out using google forms, learning outcomes documents, and interviews, then the analytical technique used was the interactive model of analysis by comparing the results of the google form questionnaire, learning outcomes, and interviews. The results of the study illustrate that online geography learning using google classroom ranges from 51% -75% only and is considered less effective due to several factors, namely network constraints, quota costs and and google classroom used in this study is not optimal. In addition, when face-to-face learning using google meet only 30% - 50% of students who follow it and some teachers do not carry out face-to-face for fear of burdening students. As a result, teachers only provide materials, media, videos, and assignments in Google Classroom, even though the average student learning outcomes are above the KKM. The conclusion in the study shows the use of google classroom when learning geography online is less effective.

Published: October 2021

В настоящее время одним из приоритетных направлений развития государства является улучшение демографической ситуации в стране, а также поддержка материнства, детства и семьи. Для реализации указанных целей российская правовая политика предусматривает различные механизмы, одним из которых является предоставление отсрочки отбывания наказания беременным женщинам, женщинам и мужчинам, являющимися единственным родителем, до достижения ребенком четырнадцатилетнего возраста. Социальное назначение данного вида отсрочки заключается в обеспечении прав детей на развитие и воспитание в родной семье. В последнее время набирает популярность суррогатное материнство, которое предусматривает вынашивание и рождение женщиной ребенка для другого лица или лиц, которые станут родителями ребенка после его рождения. При этом в российском законодательстве остаются неурегулированными некоторые вопросы, связанные с реализацией требований отсрочки отбывания наказания суррогатным матерям. В статье рассмотрены проблемы правовых последствий для суррогатных матерей, которым предоставлена отсрочка отбывания наказания, в случае передачи ребенка в соответствии с требованиями договора потенциальным родителям и предложены пути их решения.
Currently, one of the priorities of the state's development is to improve the demographic situation in the country, as well as support for motherhood, childhood and family. In order to achieve these goals, the Russian legal policy provides for various mechanisms, one of which is the provision of deferred sentence for pregnant women, women and men who are the only parent, until the child reaches the age of fourteen. The social purpose of this type of deferral is to ensure the rights of children to development and upbringing in their native family. Surrogacy, which involves the carrying and giving birth of a child by a woman for another person or persons who will become parents of the child after its birth, has recently gained popularity. At the same time, some issues related to the implementation of the requirements for postponing the serving of sentences for surrogate mothers remain unresolved in Russian legislation. In particular, this article discusses the problems of legal consequences for surrogate mothers who are granted a suspended sentence in the case of the transfer of the child in accordance with the requirements of the contract to potential parents and suggests ways to solve them.

The article analyzes the issues of organizing the investigation of murders committed in institutions that provide isolation from society. The elements of the criminalistic characteristics of these crimes are considered. The most common methods of committing penitentiary murders, typical traces and the situation of a criminal event are studied and analyzed. Special attention is paid to the study of the psychological portrait of the personality of the penitentiary criminal. It is concluded that the tactical features of the investigation of murders in places of deprivation of liberty are largely determined by the specifics of the correctional institution. The legal and organizational aspects of attracting specialists to participate in investigative actions, issues of organizing the activities of a forensic medical expert are investigated. The special importance of the urgency of conducting an inspection of the scene of the incident in the conditions of the institution of the penitentiary system is indicated.

В статье проведен общетеоретический анализ категории наказаний, не связанных с лишением свободы. Выявлены место и роль не связанных с лишением свободы наказаний в системе уголовных наказаний, применяемых в России. Выделены основные виды этих наказаний и приведены их отдельные характеристики. Системный анализ действующего законодательства позволил выделить виды наказаний, которые по соответствующим критериям могут быть причислены к таким, что не реализуются путем лишения лица свободы: штраф, ограничение свободы, исправительные работы, обязательные работы и др. Установлено, что перспективы для расширения подобных видов наказаний открыты, но механизмы их воплощения в практической деятельности нуждаются в обновлении для повышения эффективности уголовной политики. Авторами выявляются и характеризуются особенности назначения наказаний, не связанных с лишением свободы лица, в отношении которого вынесен приговор. Кроме того, авторами отмечаются основные проблемы назначения отдельных видов наказаний этой группы в современной правоприменительной практике. Подчеркивается необходимость дальнейшей научной разработки проблематики вопроса и внесения изменений и дополнений в законодательство в целях его совершенствования.
The article provides a general theoretical analysis of the category of non-custodial punishments. The place and role of non-custodial punishments in the system of criminal punishments used in Russia has been revealed. The main types of these punishments are highlighted and their individual characteristics are given. A systematic analysis of the current legislation made it possible to identify the types of punishments that, according to the relevant criteria, can be ranked among those that are not implemented by imprisoning a person: a fine, restriction of liberty, corrective labor, compulsory labor, etc., but the mechanisms of their implementation in practice need to be updated to increase the effectiveness of criminal policy. The authors identify and characterize the specifics of sentencing that are not related to the deprivation of freedom for the person who is sentenced. In addition, the authors point out the main problems of assigning certain types of punishments to this group in modern law enforcement practice. The need for further scientific development of the problematics and the introduction of amendments and additions to the legislation in order to improve it is emphasized.

Permanent press by using resin will increase the resistance of the desired material properties. The refinement process to obtain permanent fold properties in polyester fibers is obtained by forming a polymer resin layer on the surface of the fabric. The more resin used, the less the ability of the fabric to come back from the crease, so the permanent crease finish will be more permanent.
However, with more and more resin polymerizing on the surface, the fabric will be stiffer and can reduce the tensile strength of the fiber, the occurrence of the resin polymerization process is influenced by the temperature of the preserved heating when the temperature is less then the resin is not formed perfectly or if the temperature is too high it can cause damage to the fiber. This test was carried out on 100% polyester fabric with variations in the concentration of melamine formaldehyde resin 40 g/l, 50 g/l, 60 g/l, 70 g/l and variations in the curing temperature of 1600C, 1700C, 1800C, 1900C. Tests carried out include re-testing of the folds and tensile strength of the fabric. The results showed that the optimum conditions achieved in this experiment were at a concentration of melamine formaldehyde resin of 60 g/l with a preserved heating temperature of 1700C, a low folding angle value of 740 was obtained with a tensile strength value that above the minimal standards, namely the warp 75.7 Kg and weft 22.7 Kg.

Abstract
We present an open-source Python package, Orbits from Radial Velocity, Absolute, and/or Relative Astrometry (orvara), to fit Keplerian orbits to any combination of radial velocity, relative astrometry, and absolute astrometry data from the Hipparcos-Gaia Catalog of Accelerations. By combining these three data types, one can measure precise masses and sometimes orbital parameters even when the observations cover a small fraction of an orbit. The computational performance of orvara is achieved with an eccentric anomaly solver 5–10 times faster than commonly used approaches and low-level memory management to avoid Python overheads and by analytically marginalizing out parallax, barycenter proper motion, and instrument-specific radial velocity zero-points. Through its integration with the Hipparcos and Gaia intermediate astrometry package htof, orvara can properly account for the epoch astrometry measurements of Hipparcos and the measurement times and scan angles of individual Gaia epochs. We configure orvara with modifiable .ini configuration files tailored to any specific stellar or planetary system. We demonstrate orvara with a case study application to a recently discovered white dwarf/main-sequence system, HD 159062. By adding absolute astrometry to literature radial velocity and relative astrometry data, our comprehensive Markov Chain Monte Carlo analysis improves the precision of HD 159062B’s mass by more than an order of magnitude to

Abstract
Ultraviolet spectra of protoplanetary disks trace distributions of warm gas at radii where rocky planets form. We combine Hubble Space Telescope Cosmic Origins Spectrograph observations of H2 and CO emission from 12 classical T Tauri stars to more extensively map inner disk surface layers, where gas temperature distributions allow radially stratified fluorescence from the two species. We calculate empirical emitting radii for each species under the assumption that the line widths are entirely set by Keplerian broadening, demonstrating that the CO fluorescence originates further from the stars

. This is supported by 2D radiative transfer models, which show that the peak and outer radii of the CO flux distributions generally extend further into the outer disk than the H2. These results also indicate that additional sources of Lyα photons remain unaccounted for, requiring more complex models to fully reproduce the molecular gas emission. As a first step, we confirm that the morphologies of the UV–CO bands and Lyα radiation fields are significantly correlated and discover that both trace the degree of dust disk evolution. The UV tracers appear to follow the same sequence of disk evolution as forbidden line emission from jets and winds, as the observed Lyα profiles transition between dominant red wing and dominant blue wing shapes when the high-velocity optical emission disappears. Our results suggest a scenario where UV radiation fields, disk winds and jets, and molecular gas evolve in harmony with the dust disks throughout their lifetimes.
Metallicity Dependence of the H/H2 and C+/C/CO Distributions in a Resolved Self-regulating Interstellar Medium
Authors: Hu 胡 Chia-Yu 家瑜 , Sternberg Amiel , van Dishoeck Ewine F. 
Published: October 2021

Abstract
We study the metallicity dependence of the H/H2 and C+/C/CO distributions in a self-regulated interstellar medium (ISM) across a broad range of metallicities (0.1 < Z/Z
⊙ < 3). To this end, we conduct high-resolution (particle mass of 1 M
⊙) hydrodynamical simulations coupled with a time-dependent H2 chemistry network. The results are then post-processed with an accurate chemistry network to model the associated C+/C/CO abundances, based on the time-dependent non-steady-state (“nonequilibrium”) H2 abundances. We find that the time-averaged star formation rate and the ISM structure are insensitive to metallicity. The column densities relevant for molecular shielding appear correlated with the volume densities in gravitationally unstable gas. As metallicity decreases, H2 progressively deviates from steady state (“equilibrium”) and shows shallow abundance profiles until they sharply truncate at the photodissociation fronts. In contrast, the CO profile is sharp and controlled by photodissociation as CO quickly reaches steady state. We construct effective 1D cloud models that successfully capture the time-averaged chemical distributions in simulations. At low metallicities, the steady-state model significantly overestimates the abundance of H2 in the diffuse medium. The overestimated H2, however, has little impact on CO. Consequently, the mass fraction of CO-dark H2 gas is significantly lower than what a fully steady-state model predicts. The mass ratios of H2/C+ and H2/C both show a weaker dependence on

Z

than H2/CO, which potentially indicates that C+ and C could be alternative tracers for H2 at low

in terms of mass budget. Our chemistry code for post-processing is publicly available.
