Authors: Dewi Catur Kumala 
Published: May 2022

The Covid-19 outbreak gave a negative implication not only on the Indonesian stock exchange but throughout the world until WHO declared Covid-19 a pandemic. Stock market movements are formed by stock market participants, including issuers, brokers and investors. IHSG continues to fluctuate sharply and tends to decrease in the beginning of January 2020 to April 2020. Different things happen for trading volumes that have increased. Trading volume is a combination of sell and buy during the trading session. Before and after Covid-19, IHSG gives an illustration that trading volume is increasingly fluctuating sharply with an upward trend above trading volume before Covid-19. Pandemic provides an overview of IHSG volatility and trading volumes that experience sharp fluctuations with a downward trend. Therefore, reserves are better if diversification is carried out in real assets other than financial assets.

The Church Policy of Emperor Justinian I
Authors: Дьячков Герасим 
Published: May 2022

В статье раскрываются многообразные черты личности и деятельности св. императора Юстиниана I (483-565) - выдающегося военачальника, правителя, законодателя, богослова, песнотворца ранневизантийского периода, посвятившего всю свою жизнь защите интересов Церкви, охранению ее единства и вероучения, а также распространению Православия в Империи и за ее пределами. Несмотря на то, что реальная политика Юстиниана была небезупречна (как и все в мире борьбы добра и зла), он являлся поистине христианским правителем, понимающим «царствование» одновременно как власть и служение в согласии с правилами и уставами Церкви. Рассматривая основные направления церковной политики св. Юстиниана и указывая на концептуально различные мнения историков и богословов в оценках его богословских взглядов и церковно-государственной деятельности, он отвергает попытки обвинить «могущественнейшего из императоров» в уклонении от святоотеческой веры, утверждая его Православие и святость в согласии с Церковью, прославившей Юстиниана в лике святых.
The article reveals various features of the life and activities of Saint Emperor Justinian I (483-565) - a prominent military leader, ruler, lawmaker, theologian, hymnographer of the early Byzantine period, who dedicated all his life to protecting the interests of the Church, defending its unity and faith, and spreading Orthodox Christianity within the Empire and beyond. Although Justinian’s real policy was not perfect (as nothing is perfect in the world where the good struggles with the evil), he was a true Christian ruler who understood «kingship» as power together with ministry, in accordance with the rules of the Church. The author observes the main directions of Justinian’s policy and points out the divergency among historians and theologians in esteeming Justinian’s theology and church policy, to refute the attempts to blame the «Most Powerful Emperor» with renouncing the faith of the Holy Fathers. Instead, the author maintains that Justinian was Orthodox and saint - in accordance with the Church which has canonized this emperor.
The Particular Features of the Conflicts in the Parishes Belonging to the Holy Trinity-St. Sergius Lavra in the 18th Century (In the Rozhdestvenskyand Serebozhsky Districts of Pereslavl Uyezd)
Authors: Дмитриев Георгий Сергеевич 
Published: May 2022

Статья посвящена специфике конфликтов между клиром (и внутри клира) вотчинных храмов Троице-Сергиева монастыря в Рождественском и Серебожском станах Переславского уезда в ХVIII в. В древнем селе Махра, переданном монастырю Ловчиковыми в 1572 г., настоятельское место передавалось от отца к сыну на протяжении полутора столетий, так же обстояло дело и с другими церковными должностями. Но в середине 1750 г., после разборов церковных штатов, на должности в храме Рождества Пресвятой Богородицы стала претендовать семья Григория Заболотского (отца будущего ректора Троицкой семинарии), не принадлежавшая с. Махра, но которого поддержало поместное дворянство. За наследственные места развернулась продолжительная борьба, завершившаяся в 1770-х гг. в пользу исконной священнической династии священника Наума (Орлова). Кадровый и территориальный вопрос легли в основу конфликтов в селе Константиновском, клир которого боролсяне только за свои наследственные права, но и за границы своего прихода (в разное время конфликты приобретали как межприходской, так и внутриприходской характер). Архиереи Переславско-Дмитровской епархии решали замену штатных должностей, как правило, в пользу коренной священнической династии, учитывая также и настроение прихожан.
The article is devoted to the particular features of the 18th-century conflicts among the clergy of the churches belonging to the Holy Trinity-St. Sergius Lavra which were located in the districts (Russ.: stan, volost) Rozhdestvensky and Serebozhsky of Pereslavl uyezd. In the old village (Russ.: selo) of Makhra, donated to the monastery in 1572 by Lovchikov family, the position of Father Superior was hereditary for a century and a half; as for the other church positions, the situation was similar. But in the mid-1750, after an allotment of church positions, a conflict arose as the family of Grigoriy Zabolotsky, father of the future rector of the Trinity Seminary, also aspired to the positions in Makhra’s Church of the Nativity of the Theotokos (this family did not pertain to Makhra but was supported by the local nobility). The long-lasting struggle for the hereditary positions finished in the 1770s when the positions eventually remained with their original obtainers - the family of Priest Naum Orlov. In Konstantinovskoye village (Russ.: selo) the matters of positions and land also became the ground of the conflicts between clergymen who struggled for hereditary rights and for the borders of their respective parishes (parish conflicts would be internal or inter-parish at different times). The bishops of the diocese of Pereslavl-Zalessky and Dmitrov would nearly always solve questions of position in favour of the aboriginal clergy family, also taking into account the parishioners’ feelings.

Published: May 2022

In this research paper, a new methodology to design a progressive and win-win royalty model for upstream fiscal systems is developed. The proposed royalty model is designed as a function of different boundary conditions of the market and the productive resources. These boundary conditions include the associated exploration and production risks, commodity prices, the extraction costs, besides the expected production and depletion rate. The behavior of the proposed royalty model under different oil prices, development costs, production rates, and exploration risks is investigated using deterministic and stochastic analysis. Our results prove that the applicable royalty rate increases with both the price and production rate while it decreases with increasing the development costs and the associated exploration and production risks. In addition, the proposed royalty model provides the contractor with sufficient incentives to develop marginal or low profitability fields and the development of deep offshore or frontier fields with high development and operating costs.

Published: May 2022

The flying agility demonstrated by dragonflies is accomplished by means of complex aerodynamic forces produced by flapping their four wings arranged in a tandem configuration. The current study presents a novel tandem flapping wing mechanism for a biomimetic air vehicle that was designed and manufactured to experimentally investigate the aerodynamic forces. By optimizing the configuration and using spatial network analysis, it is shown that the designed structure can flap the wings in a linear up–down stroke motion and is capable of maintaining good consistency and aerodynamic performance. Such a mechanism could be used in a future biomimetic micro air vehicle (BMAV) design. The mechanism uses an electromagnetic actuator to flap the wings with a variable beat frequency (30–210 Hz) at various angles of attack (−10°–20°). The results show that the tandem wings generate approximately 50% higher lift than the forewing or hindwing pairs acting alone. Tandem wings also improve stability, which could potentially allow hovering.

Published: May 2022

In the present work, we evaluated the potential of maslinic acid (MA) to improve currently available keratinocyte culture methods for use in skin tissue engineering. Results showed that MA can increase cell proliferation and WST-1 activity of human keratinocytes after 24, 48, and 72 h, especially at the concentration of 5 μg/ml, without affecting cell viability. This effect was associated to a significant increase of KI-67 protein expression and upregulation of several genes associated to cell proliferation (PCNA) and differentiation (cytokeratins, intercellular junctions and basement membrane related genes). When human keratinocytes were isolated from skin biopsies, we found that MA at the concentration of 5 μg/ml significantly increased the efficiency of the explant and the cell dissociation methods. These results revealed the positive effects of MA to optimize human keratinocyte culture protocols for use in skin tissue engineering.

Published: May 2022

With the continuous improvement in oilfield development and the application of tertiary oil recovery technology, the water content of oilfield-produced fluids has gradually increased, and a large number of oilfield sewage with complex components has also been produced after oil–water separation, and effective treatment is urgently needed. ASP flooding sewage contains alkali, various surfactants, polymers, microemulsion oil droplets, and solid impurities, which are difficult to be effectively treated by traditional water treatment agents and methods. In this study, aminopropyl triethoxysilane (APTES) was used to modify the nano-Fe3O4 coated with tetraethyl silicate (TEOS). The product was used as the ferromagnetic nano-core for the iterative reaction of Michael addition and ester amidation to synthesize a magnetic hyperbranched polyamide amine, and its performance in the treatment of ASP flooding wastewater was evaluated experimentally. For the preparation of APTES-modified Fe3O4@SiO2 (FOSN) product, TEOS was coated over Fe3O4 in an ethanol aqueous solution environment and then APTES was added dropwise. The first-generation branched product (1-FSMN) was obtained by the reaction of FOSN and methyl acrylate graft product (FOSN-M) with ethylenediamine, and the highest yield was 93.7%. The highest yield of the second-generation branched product (2-FSMN) was 91.6%. In this study, a composite flooding wastewater sample from a block in the Bohai oilfield was taken. The suspended solids content was 143 mg/L, the oil content was 921.09 mg/L, the turbidity was 135 NTU, and the zeta potential was −47 mV. The third-generation hyperbranched polymer (3-FSMN) and its quaternary ammonium salt (3-FSMN-Q) performed best in the appropriate dosage range, with the highest oil removal rate of 97%, suspended solid removal rate of 90.3%, turbidity reduction rate of 86.6% and zeta potential reduction rate of 88%. For 3-FSMN and its quaternary ammonium salt, the gravity/magnetic PAC compound treatment experiment was carried out. In the settlement time of only 5 min, 3-FSMN/PAC and 3-FSMN-Q/PAC can achieve the maximum oil removal rate of 87.1% and suspended solids removal rate of 87.3% for polymer containing wastewater from ASP flooding, and 86.3 and 86.0% for 120 mg/L. Its treatment capacity was much better than that of common treatment agent combination (CPAM/PAC).

Published: May 2022

BackgroundBoth sodium-glucose co-transporter-2 (SGLT-2) inhibitors and angiotensin receptor-neprilysin inhibitor (ARNI) were recommended to treat heart failure with reduced ejection fraction (HFrEF). However, no trial was conducted to assess the efficacy and safety of the combined therapy of SGLT-2 inhibitors and ARNI in patients with HFrEF.MethodsWe performed a meta-analysis of the prespecified subgroups from DAPA-HF and EMPEROR-Reduced trials. The primary endpoint was the composite risk of cardiovascular death or hospitalization for heart failure. The risk of cardiovascular death, all-cause death, a composite of serious adverse renal outcomes, and volume depletion were also estimated.ResultsThe risk of the composite of cardiovascular death or hospitalization for heart failure was reduced in combined therapy of SGLT-2 inhibitors and ARNI, compared with ARNI monotherapy (RR.68, 95% CI.53 to.85, P = 0.001). When compared with SGLT-2 inhibitors monotherapy, the events of cardiovascular death (RR.64, 95% CI.46 to 0.87, P = 0.005) and all-cause death (RR.72, 95% CI.55 to.94, P = 0.01) were significantly less in combined therapy, accompanied by elevated incidence of volume depletion (RR 1.55, 95% CI 1.22 to 1.96, P = 0.0003).ConclusionCombined therapy has additional benefits over monotherapy in patients with HFrEF, however, it is accompanied by a possibly higher risk of volume depletion.
