Authors: Скурко Евгения Романовна , Щевелёва Ангелина Васильевна 
Published: February 2021

Статья посвящена малоизвестной опере «Уриель Акоста» Валентины Серовой - русского композитора, общественного деятеля, музыкального критика. Определяется идея оперы, очерчивается главный драматургический конфликт, а также рассматривается один из важнейших интонационных пластов оперы, связанный с еврейской народной и синагогальной музыкой. Выявляются особенности их претворения на уровнях ладовой, интонационно-ритмической и фактурной организации музыкального текста. В качестве примера претворения народной песенной традиции анализируется Колыбельная. Принципы речитации и кантилляции, типичные для синагогальной музыки, прослеживаются в Молитве Эсфири и Рахили. Однако наиболее последовательно данная традиция раскрывается в кульминационной Сцене в синагоге, где воспроизводятся структура и характерная лексика иудейского ритуала.
The article is devoted to the little-known Opera “Uriel Acosta” by Valentina Serova a Russian composer, public figure, and music critic. The idea of the opera is defined, as well as the main dramaturgical conflict. For the first time, we consider one of the most important intonation layers of the opera associated with Jewish folk and synagogue music. The features of their implementation at the levels of modal, intonation-rhythmic and textural organization of the musical text as a whole are revealed. The Lullaby is analyzed as an example of implementation of Jewish folk tradition. The principles of recitation and cantillation typical of synagogue music are analysed in the Prayer of Esther and Rachel. However, this tradition is most consistently revealed in the culminating Scene in the synagogue, where V. Serova reproduces the structure and characteristic vocabulary of the Jewish ritual service.

Статья освещает вопрос о связях Балакирева и Монюшко, который остался практически не затронутым исследователями их жизни и творчества. В музыковедческой литературе об этом можно почерпнуть лишь единичные факты. Их удалось существенно дополнить впервые вводимыми в научный обиход сведениями из документальных источников, среди которых несколько обнаруженных нами неизвестных автографов писем и нотных рукописей, печатных изданий из библиотеки и архива Милия Алексеевича. Все это позволило установить истинную картину многогранных творческих взаимоотношений двух композиторов, где в роли главного связующего звена выступала музыка Монюшко. В свою очередь, это не только проясняет забытые страницы в биографиях музыкантов, но и вносит вклад в разработку таких фундаментальных тем, как «Балакирев и Польша», «Русско-польские музыкальные связи».
This article highlights the question of the relationship between Balakirev and Moniuszko, which has remained virtually untouched by researchers of their life and work. Only a few facts can be found in the scientific literature about this. They were significantly supplemented with information from documentary sources that was introduced into scientific use for the first time. Among them are several unknown autographs of letters and music manuscripts discovered by us, as well as printed publications from the library and archive of Mili Alexeeyevich. All this allowed us to establish a true picture of the multifaceted creative relationship between the two composers, where Moniuszko's music served as the main link. In turn, these materials not only clarify the forgotten pages in the biographies of both musicians, but also contribute to the development of such fundamental themes as “Balakirev and Poland,” “Russian-Polish musical ties.”

Published: February 2021

Artikel ini bertujuan untuk melihat bagaimana peranan Persatuan Muballigh Batam (PMB) terhadap kehidupan beragama di Kota Batam dengan metode telaah pustaka dan wawancara dengan pihak-pihak terkait. Batam sebagai daerah metropolitian dihuni beraneka suku dan beragam pemeluk agama sehingga sangat rentan sekali terjadi gesekan dengan alasan keagamaan. Meskipun setiap agama mengajarkan pada kedamaian, namun pemahaman dari setiap pemeluknya bisa menimbulkan perbedaan pendapat sehingga konfelik bisa muncul di intra umat beragama itu sendiri dan di luarnya. Dalam hal ini, PMB sebagai salah satu organisasi yang mewadahi para penceramah memiliki andil dalam menjaga kedamaian di Batam. Dari hasil penelitian ini, PMB sering terlibat dalam hal sikap intoleransi keagamaan dengan memberikan penjelasan dan masukan kepada pihak-pihak terkait. Bahkan apabila suatu sikap terdapat kasus yang intoleran, PMB menyarankan agar kasus ditindaklanjuti secara bijak oleh pihak terkait agar tidak menimbulkan ekses yang berkepanjangan. PMB menegaskan bahwa anggotanya wajib perpaham ahlussunah wal jamaah dengan mengakui adanya sifat Allah dan anggotanya wajib menjadi tauladan di lingkungan masing-masing.

ABSTRACT: This article aims to see how the role of the Persatuan Muablligh Batam (PMB) on religious life in Batam City by means of literature review and interviews with related parties. Batam as a metropolitan area is inhabited by various ethnic groups and various religious adherents so that it is very vulnerable to friction for religious reasons. Although every religion teaches peace, the understanding of each adherent can lead to differences of opinion so that conflict can arise within the religious community itself and outside it. In this case, PMB as one of the organizations that accommodates the lecturers has a role in maintaining peace in Batam. From the results of this study, PMB is often involved in religious intolerance by providing explanations and input to related parties. Even if there is an attitude of intolerant cases, PMB recommends that the case be followed up wisely by the related parties so as not to cause prolonged excess. PMB emphasized that its members are obliged to understand ahlussunah wal jamaah by acknowledging the nature of Allah and its members are obliged to become role models in their respective environments.

Abstract
The Event Horizon Telescope (EHT) is a very long-baseline interferometer built to image supermassive black holes on event-horizon scales. In this paper, we investigate candidate sites for an expanded EHT array with improved imaging capabilities. We use historical meteorology and radiative transfer analysis to evaluate site performance. Most of the existing sites in the EHT array have median zenith opacity less than 0.2 at 230 GHz during the March/April observing season. Seven of the existing EHT sites have 345 GHz opacity less than 0.5 during observing months. Out of more than 40 candidate new locations analyzed, approximately half have 230 GHz opacity comparable to the existing EHT sites, and at least 17 of the candidate sites would be comparably good for 345 GHz observing. A group of new sites with favorable transmittance and geographic placement leads to greatly enhanced imaging and science on horizon scales.
Confirmation of Asymmetric Iron Absorption in WASP-76b with HARPS
Authors: Kesseli Aurora Y. , Snellen I. A. G. 
Published: February 2021

Abstract
Hot Jupiters are predicted to have hot, clear daysides and cooler, cloudy nightsides. Recently, an asymmetric signature of iron absorption has been resolved in the transmission spectrum of WASP-76b using ESPRESSO on ESO’s Very Large Telescope. This feature is interpreted as being due to condensation of iron on the nightside, resulting in a different absorption signature from the evening than from the morning limb of the planet. It represents the first time that a chemical gradient has been observed across the surface of a single exoplanet. In this work, we confirm the presence of the asymmetric iron feature using archival HARPS data of four transits. The detection shows that such features can also be resolved by observing multiple transits on smaller telescopes. By increasing the number of planets where these condensation features are detected, we can make chemical comparisons between exoplanets and map condensation across a range of parameters for the first time.
The GN-z11-Flash Event can be a Satellite Glint
Authors: Nir Guy , Ofek Eran O. , Gal-Yam Avishay 
Published: February 2021

Abstract
Recently Jiang et al. reported the discovery of a possible short duration transient, detected in a single image, spatially associated with a z ∼ 11 galaxy. Jiang et al. and Kann et al. suggested the transient originates from a γ-Ray Burst (GRB), while Padmanabhan & Loeb argued the flash is consistent with a supernova shock breakout event of a 300 M
⊙ Population III star. Jiang et al. argued against the possibility that this event originated from light reflected off a satellite. Here we show that reflection of sunlight from a high-orbit satellite or a piece of space debris is a valid and reasonable explanation. As shown in recent works, the rate of point-like satellite reflections, brighter than 11th magnitude, is >10 deg−2 day−1 near the equatorial plane. At higher declinations the rate is 5–50 times lower, but still significant: about four orders of magnitudes higher than the rate estimated for GRBs.

Aims: Trithrinax campestris is one of the palm species with the southernmost distribution in the Neotropics. Despite that the vegetation types in which T. campestris occurs are nowadays heavily threatened by land use and land cover changes, their floristic composition and structure are still to be documented. In order to characterize T. campestris habitats, the aim of this study was to describe the floristic composition of the vegetation types in which this palm occurs and their relationships with different environmental factors.
Study area: The survey was conducted in central Argentina in an area comprising the southern extreme of the distribution of T. campestris in the following phytogeographic areas: Espinal, Lowland and Mountain Chaco.
Methods: Following the Braun-Blanquet approach we collected 92 floristic relevés recording a total of 601 vascular plant species. Vegetation was classified through the ISOPAM hierarchical analysis. Bioclimatic and elevation data were related to the floristic data through the ISOMAP ordination. Remote-sensed images (Landsat TM, ETM+ and OLI) were used to characterize the fire frequency in the 92 stands.
Results: Four vegetation types that differed in floristic composition and in diagnostic species were discriminated: 1.1 Celtis tala/Sida rhombifolia closed forest; 1.2 Aspidosperma quebracho-blanco/Prosopis kuntzei open forest; 2.1 Jarava pseudoichu/Vachellia caven open savanna; and 2.2 Acalypha variabilis/Nassella cordobensis scrubland. The ISOMAP ordination showed that differences in floristic composition were related to elevation, topography and climatic variables.Out of the 92 stands, only 21 showed the occurrence of fires during the period 1999–2018.
Conclusions: Our results evidenced that vegetation types (forests, savannas and scrublands) comprising T. campestris developed in a wide range of environmental conditions. This is the first study that focuses on all vegetation types in which T. campestris occurs in central Argentina and it is relevant for conservation and sustainable management of the only native palm species in the flora of this part of the country.

ENHANCING THERMAL COMFORT OF RESIDENTIAL BUILDINGS THROUGH DUAL FUNCTIONAL PASSIVE SYSTEM (SOLAR-WALL)
Authors: Mabdeh Shouib , Al Radaideh Tamer , Hiyari Montaser 
Published: February 2021

ABSTRACT
Thermal comfort has a great effect on occupants’ productivity and general well-being. Since people spend 80–90% of their time indoors, developing the tools and methods that help in enhancing the thermal comfort for buildings are worth investigating.
Previous studies have proved that using passive systems like Trombe walls and solar chimneys significantly enhanced thermal comfort in inside spaces despite that each system has a specific purpose within a specific climate condition. Hence, the main purpose of this study is to design and configure a new dual functional passive system, called a solar wall.
The new system combines the Trombe wall and solar chimney, and it can cool or heat based on building needs. Simulation software, DesignBuilder, has been used to configure the Solar Wall and study its impact on indoor operative temperature for the base case. Using the new system, the simulation results were compared with those obtained in the base case and analyzed to determine the most efficient system design parameters and implementation method. The case that gave the best results for solar wall configuration was triple glazed glass and 0.1 cm copper as an absorber (case 11). The results show that using four units (case D) achieves longer thermal comfort levels: 15 to 24 thermal hours during winter (compared to five hours maximum) and 10 to 19 comfort hours in summer (compared to zero).

Published: February 2021

ABSTRACT
This paper introduces methodologies and optimal strategies to reduce the energy consumption of the building sector with the aim to reduce global energy usage of a given .region or country. Many efforts are underway to develop investment strategies for large-scale energy retrofits and stricter energy design standards for existing and future buildings. This paper presents a study that informs these strategies in a novel way. It introduces support for the cost-optimized retrofits of existing, and design improvements of new buildings in Turkey with the aim to offer recommendations to individual building owners as well as guidance to the market. Three building types, apartment, single-family house and office are analyzed with a novel optimization approach. The energy performance of each type is simulated in five different climate regions of Turkey and four different vintages. For each vintage, the building is modelled corresponding to local Turkish regulations that applied at the time of construction. Optimum results are produced for different goals in terms of energy saving targets. The optimization results reveal that a 50% energy saving target is attainable for the retrofit and a 40% energy saving target is attainable for new design improvements for each building type in all climate regions.
