The Director and the Revolution: V. E. Meyerhold's Public Activity at the Mariinsky Theatre at the turn of 1917 and 1918
Authors:   Herzen State Pedagogical University of Russia, Gordeev Petr N.
Published: September 2024

At the end of 1917 Vsevolod Meyerhold paid great attention to social work in the Mariinsky Opera Company. Among the anti-Bolshevik actors of the Alexandrinsky Theatre, the direc- tor, who chose the path of rapprochement with representatives of the Soviet government, was in comparative isolation. While in Mariinsky Theatre there was the circle of like-minded opera actors. The most important of the latter was the conductor Nikolay Malko. Together with Meyerhold he supported the power of the Bolsheviks. Meyerhold and Malko devoted considerable time to the general meetings of the troupe (most of which were chaired by Meyerhold in December 1917 and early January 1918). They acted in several directions at once. Meyerhold and his supporters consistently engaged in discrediting in the eyes of the singers the manager of the opera company A.I. Siloti and the chief commissioner for state theatres F. D. Batyushkov. Both of the last theatre directors (opponents of the Bolsheviks) were showed in every possible way as the opposed ones to the democratic collective. Any actions of A. V. Lunacharsky and his comrades, even the most authoritarian, received a different as- sessment, it was emphasized that they corresponded to the interests of the actors. Hard work was rewarded: as a result, Meyerhold managed to prepare Lunacharsky's first visit to the state theatres formally led by him, which took place on January 3, 1918 in the Mariinsky Theatre and became an important milestone on the path of the “Bolshevization” of the Russian stage. Meyerhold's role in this process was very significant: he not only personally introduced the People's Commissar to the troupe, but also actually directed all the behind-the-scenes activities, which resulted in Lunacharsky's arrival at the “Petipa House”.

Authors: Abbas Basim Aboud , Jasim Abdulrazzak A. , Bander Luma K.
Published: September 2024

The experiment aimed to compare different methods of measuring the Feed pellet durability through the effect of pellet die speeds and the particle size (mill sieve holes diameter). Feed pellet durability was studied in four different ways: pellet direct measurement (%), pellet lengths (%), pellet water absorption (%), pellet durability by drop box device (%), pellet durability by air pressure device (%). Three pellet die speeds 280, 300, and 320 rpm, three mill sieve holes diameter 2, 4, and 6 mm, have been used. The results showed that increasing the pellet die speeds from 280 to 300 then to 320 rpm led to a significant decrease in the feed pellet durability by direct measurement, drop box device, and air pressure device, while pellet water absorption a significant increased, whereas it did not significantly affect the pellet lengths. Increasing the sieve holes diameter from 2 to 4 then to 6 mm led to a significant decrease in the feed pellet durability in pellet lengths, drop box deviceand air pressure device, pellet water absorption increased, whereas it did not significantly affect the direct measurement of pellet. Pellet die speeds of 280 rpm and the sieve holes diameter of 2 mm recorded the highest pellet durability for all ways: direct measurement 94.66 %, pellet lengths 85.94%, the drop box device 93.42% and the air pressure device 91.21%, less pellet water absorption 38.98%.

Role of Polyethylene Glycol in production of Anticancer Alkaloids Vincristine, Vinblastine, and Vindoline in Catharanthus roseus via Callus Culture
Authors: Abdulwahid Zainab , Al-Musawi Abdulminam Hussien Ali , Lafta Abdullah Hamad
Published: September 2024

Periwinkle Cathranthus roseus  is an ornamental plant that produces over 200 alkaloids, including vincristine, vinblastine, and vindoline, which are used to treat various types of cancer. However, the low yield of terpenoid indole alkaloids (TIAs) from periwinkle and the high cost of extraction has led researchers to explore alternative methods for their production. The study aims to investigate the influence of polyethylene glycol (PEG) as an elicitor to enhance alkaloid production in periwinkle callus cultures while examining the efficacy and safety of using PEG. Callus was induced and abiotic elicitation experiments were conducted to study callus growth enhancement. The dry weight of the callus was calculated, and vincristine, vinblastine and vindoline were extracted and analyzed using high-performance liquid chromatography. The results showed that low to moderate concentrations of PEG4000 can enhance callus growth, while higher concentrations can reduce it. The addition of PEG4000 also increased the production of important alkaloids, including vindoline, vincristine, and vinblastine, by up to 2.65-fold. The findings suggest that PEG4000 can be used to optimize the production of alkaloids in C. roseus callus cultures.

The target of the manuscript is to quantify and examine the effects of public saving on agricultural and fishing investments for the government and private sectors and economic growth in Iraq for the period 2005-2021. Econometric tools were used to clarify the impact (autoregressive model with distributed lag periods). The findings show that there is cointegration relationship between public saving (S) independent variable, government investments in agriculture, and fishing (GI) dependent variable, private sector investments in agriculture, fishing (PI) dependent variable, and economic growth (GDP) dependent variable, Moreover the value of the error correction parameter significant Generally speaking at the degree of negative (1%) and (5%) for all variables. The results indicated that there was a significant and positive short-term relationship between (S) and (GI) at a significance level (5%), in addition to the absence of a lengthy effect between the two elements that during the study period. There is also no substantial impact of public saving on private investment in agriculture, forestry, and hunting during the research period, neither in the short term nor in the long term. The results also showed that there is a significant and positive short-term relationship between (S) and (GDP), and the presence of a long-term favorable impact at a substantial degree (5%), which means that increasing public saving by one unit results in a rise in GDP of (0.001577). Conversely, a decrease in public saving by one unit leads to a decrease in GDP by the same amount, assuming other factors remain constant. This report suggests that the Iraqi government be given more authority through its economic policies in driving savings and employing it towards investment in the agriculture industry to boost and diversify agricultural output.

A Conversational Analysis of Hausa Business and Social Interaction
Authors: Muhammad Sani Abdullahi , Muhammad Ali Umar
Published: September 2024

Conversational Analysis research aims to analyze the interaction or talk rather than the language. The paper analyzed the floor of conversation in Hausa interactions of business dialogue. The data were collected through the observation procedure. The conversational Analysis approach proposed by Sacks, Schegloff, and Jefferson (1974) is used to analyze the data. Conversational analysis is used because it allows the researcher(s) to analyze the collected data based on talk in social interactions. The study revealed that, in Hausa business conversation the buyer starts the turn before allowing the seller to take up the floor. Sometimes he may decide to hold the turn for a long time. In some situations the seller may have only a few things to say such as ‘Eh’, ‘To’ or ‘a’a’ (yes, okay, or no). The research found that social setting discourse has some features that differ from business conversation, such as overlap in speeches, where you can have two or more interlocutors talking at the same time or participants trying to take their turn at the same time after the previous speaker had finished or is about to finish his turn.

A infertilidade afeta milhões de mulheres e pode ter causas biológicas e ambientais, como desequilíbrios hormonais, doenças e fatores de estilo de vida. Técnicas como a fertilização in vitro (FIV) e a injeção intracitoplasmática de espermatozoides (ICSI) são utilizadas para tratar esses casos. No entanto, mesmo com avanços, as taxas de sucesso ainda são limitadas. A compreensão dos mecanismos moleculares envolvidos na fertilização e os impactos das mutações genéticas têm sido cruciais para o desenvolvimento de tratamentos personalizados e novas tecnologias de contracepção. Este estudo realiza uma revisão sistemática, focando em avanços nas técnicas de fertilização assistida. A personalização dos tratamentos e a identificação de lacunas na literatura são destacadas. Os resultados mostram a necessidade de mais estudos para validar novas técnicas e explorar seu impacto econômico. Dos 200 estudos iniciais, apenas 5 foram incluídos na análise final. O estudo identificou proteínas críticas na fusão de gametas, como IZUMO1 e JUNO, e explorou mutações genéticas associadas à falha de fertilização, destacando o gene PLCZ1. Também foram abordados os efeitos benéficos da melatonina na qualidade dos óvulos e os avanços no uso do software SiD para a seleção de espermatozoides, melhorando as taxas de fertilização e desenvolvimento de blastocistos. Os estudos avançam no entendimento da fertilização e trazem novas ferramentas, como o biomarcador ACTL7A e o software SiD, mas ainda existem lacunas a serem investigadas. Mais pesquisas são necessárias para aprimorar as tecnologias de reprodução assistida e criar métodos anticoncepcionais mais eficazes.
Develop methods for anonymizing data for privacy-preserving AI
Authors: Prudhvi Singirikonda
Published: September 2024

This paper looks into the problem of privacy-preserving data publication in cloud computing, which is crucial for preserving the confidentiality of the data and using it for analytical purposes. To address this problem, we have introduced a new heuristic approach to anonymization that enhances data utility while ensuring appropriate levels of data privacy. In our methodology, we apply sophisticated simulation models to evaluate the efficiency of the anonymization method under different data sets. The main results prove that the improvement in the privacy metrics is significant compared to the prior techniques and without making substantial compromises on the usability of the data. Based on these findings, the authors believe that the generalized technique presented in this work could be implemented in genuine cloud computing environments as a powerful tool to address data privacy issues. As the final discussion, this paper presents the real-life significance of implementing this technique and future research recommendations that could expand the scope by experimenting with scalability and more optimization to handle the large volume of data and complications.
CREATE SOLUTIONS FOR VERSIONING AND MANAGING DATASETS USED IN AI AND ML.
Authors: Sukender Reddy Mallreddy
Published: September 2024

It is also essential to correctly version and manage datasets to make them easily recognizable, traceable, and sharable throughout the various stages of AI & ML model development. Notably, there are many solutions to dataset versioning and management, with the best one touching on existing machine learning pipelines, highlighted by tools like DVC and MLflow, in this paper. To achieve this, the study provides simulation reports on using these tools in the current dynamic data environments, including healthcare, finance, and e-commerce, requiring robust version control mechanisms to counter quickly evolving data. Potential issues such as scale, data accuracy, and compatibility with present system adoptions are discerned with suggested solutions such as cloud-based management, checks and balances on data integrity, and ease of integration. The use of visuals shows how data lineage visualization helps in understanding the data flow for better implementation of measures and how different versioning tools compare in performance. The conclusions drawn from the study pertain to the fact that the implementation of structured data versioning strategies contributes to the enhancement of model quality and efficiency in addition to enhancing interaction between data scientists and engineers. This research finds that proper methods of developing and applying data versioning and data management practices are critical for effectively implementing AI and ML models in complex ecosystems that make decisions based on the most contemporary data. Future work will investigate the applicability of these tools as the number of data points to process increases, as well as the variability of those data points.

Published: September 2024

"Enhancing business competitiveness and empowering Micro, Small, and Medium Enterprises (UMKM) is crucial for sustainable economic development. Law Number 20 of 2016 serves as a legal policy, with trademark protection being a key aspect in strengthening the position and contribution of UMKM in an increasingly complex market competition. This research explores the roles and challenges faced by UMKM. Through analysis of various related literature, it is found that UMKM often encounter obstacles in understanding and implementing trademark protection.This study adopts a normative juridical approach through literature review to identify concepts relevant to the issues of trademark protection for UMKM. The research results indicate that the legal policies governing UMKM, such as Republic of Indonesia Law Number 20 of 2008 concerning UMKM and Law Number 20 of 2016, can serve as government methods to provide business protection to UMKM through the protection of their intellectual property in the form of trademarks. The recognition of trademarks shared among UMKM serves as a means to protect their intellectual property against large industries or other business entities that may attempt to obtain intellectual property owned by UMKM without proper authorization. Disputes arising from trademark ownership are typically resolved based on the trademark certificate as evidence of ownership, unless the trademark is invalidated through trademark litigation brought before the Commercial Court. UMKM associations can serve as bridges for UMKM to access information, business networks, and even skill development opportunities, thereby enhancing the capabilities of UMKM.

The wetland ecosystem represents a crucial ecological resource, supporting diverse flora and fauna while providing essential services to the local communities. However, rapid human settlement within its environment has raised concerns to play it important functions. The study assessed the effect of human settlement on wetland ecosystem sustainability at Lake Kenyatta Wetland in Lamu West Sub-County. This study adopted descriptive research design. The target population of the study was 2750 persons comprising of households from Lamu West Sub-County, three chiefs, and three sub-chiefs surrounding Lake Kenyatta Wetland Ecosystem and four environmental officers from Lamu County. The sample size of the study was 185 respondents; it was determined using Krejcie & Morgan (1970) formulae. Primary data was collected using questionnaires and interview guides. Quantitative data was analyzed using descriptive statistics in the form of means, and percentages and presented in tables and figures. The study findings on effect of human settlement showed that majority of the respondents 93.8% agreed that human settlement practices have hindered the long-term sustainability and resilience of Lake Kenyatta wetland, and thus human activities can introduce invasive plant and animal species into wetlands. In conclusion, human settlement has affected the ecological health and balance of the wetland ecosystem. The impact of human activities has led to degradation, habitat destruction, and hindered long-term sustainability of the lake. The study recommended that stakeholders engage in comprehensive community consultations and awareness programs. Collaborative efforts involving local authorities, environmental agencies, and community leaders are crucial for implementing sustainable policies that balance economic opportunities with environmental preservation
Cartographic materials for studying the historical geography of Northwest Russia
Authors: Andreeva Tatyana
Published: September 2024

The historical process in the North-West Russia is characterized by complexity and versatility. Over the centuries, this region has witnessed a variety of historical events, changes in political and administrative boundaries, the founding of cities, the establishment of new communication routes, and the decline of old ones, alongside the growth of industry and trade. These changes were interconnected and mutually influential, highlighting the need for a comprehensive examination of all these phenomena. The spatial positioning of various geographical objects and phenomena is particularly significant, as it helps us understand why their interactions occurred in the ways they did. To grasp these spatial relationships, however, complex maps are necessary, ones that simultaneously depict different types of objects and phenomena.
This article addresses the portrayal of North-West Russia's historical development on complex historical and geographical maps spanning from the 5th-6th centuries AD to the early 21st century. It includes a review of the sources used in creating the maps. The article also analyzes the challenges faced in mapping various types of objects and outlines solutions to these problems. Additionally, it presents a periodization of the historical process in the region, developed during the creation of the maps.
Ecological conflict within the concept of extractivism (on the example of the Ust-Luga company and the local community)
Authors: Bocharnikova Aleksandra
Published: September 2024

The concept of extractivism describes social processes when the least protected social groups of society protest against the activities of companies in the process of resource extraction. In many countries, the raw materials economy is predominant, and in the territory where resource extraction takes place, the dominant society and the indigenous population are opposed. In the Kingiseppsky District of the Leningrad Region, the indigenous population are the peoples of the Finno-Ugric language group (Vods and Izhora), whose main occupation in the past was fishing. The aim of the study is to consider the conflict between the residents of the Ust-Luga rural settlement and the port of Ust-Luga from the point of view of the concept of extractivism. Beginning in the 19th century, the traditional economy underwent significant changes, but until the construction of the port in Ust-Luga in the 1990s, the local population continued to work at the cannery. After the construction of the coal and oil terminals, the cannery was closed, and migrants from other regions began to work at the terminals. The article presents recommendations for the implementation of a special policy by the Ust-Luga company, including improving the infrastructure of villages, financing tourism activities, including those related to museums of the Vot and Izhora culture, and carrying out activities to preserve the historical and natural heritage of the territory.
Experience of assessing changes in metethnic heterogeneity of Central Asia territories from 1970 to 1989
Authors: Nikolaeva EVDOKIYA
Published: September 2024

Currently, there is interest in analyzing the ethno-demographic situation in the countries of Central Asia. Ethno-demographic processes in this macroregion in the late Soviet period have been less studied. The purpose of the study is to assess changes in the heterogeneity of the population structure for two large meta-ethnic groups (indigenous and non-indigenous population) in the regions of Central Asia during the intercensal periods from 1970 to 1979 and from 1979 to 1989. Based on the value of the modified index of meta-ethnic heterogeneity, the following were identified: territories that are homogeneous in meta-ethnic terms and dominated by the indigenous population (in the south of the macroregion); dimly and clearly defined contact zones (in the southern part of Central Asia with a preponderance of the indigenous population, in the northern part with a preponderance of the non-indigenous population); the most clearly defined contact zones (a belt of regions separating the meta-ethnically contrasting northern and southern parts of the macroregion). Between 1970 and 1979 in the southern part of Central Asia, the dissolution of contact zones in favor of the indigenous population prevailed; in the northern part, meta-ethnic contact grew as the proportion of indigenous peoples increased. From 1979 to 1989 in the southeast of the macroregion, a large array of meta-ethnically homogeneous territories emerged; in the middle part, the number of regions that moved to the dissolution of contact zones in favor of the indigenous population increased. By 1989, there were only a few regions left in the north of Kazakhstan, where the predominance remained in favor of the non-indigenous population.
OPTIMIZATION OF CULTIVATION CONDITIONS OF A NEWLY ISOLATED STRAIN CHLORELLA SP. LH2 FOR COOKING COCOON WASTEWATER TREATMENT
Authors: Le Thi Anh Tu
Published: September 2024

Cooking cocoon wastewater contains large quantities of biodegradable nutrients such as nitrogen, phosphorous, and other compounds that microalgae can consume for their growth. In this study, locally isolated Chlorella sp. LH2 was investigated as a means to remove contaminants in wastewater treatment. This alga can grow under a wide range of cultivation conditions. The results showed that Chlorella sp. LH2 grew well in cocoon wastewater and removed nutrients. The optimal cultivation conditions were determined for a variety of initial dry cell densities, temperatures, pH, and light-dark cycles. The maximum growth rate of Chlorella sp. LH2 was achieved at 25 °C, a pH of 8, a light-dark cycle of 16:08, and an initial dry cell density of 1.5 mg/l. Chlorella sp. LH2 exhibited nutrient removal efficiencies of 89.84%, 90.01%, and 93.44% for total nitrogen, NH4+-N, and total phosphorous, respectively. The high BOD5 and COD removal efficiencies of 91.78% and 87.34%, respectively, indicate that Chlorella sp. LH2 can be considered an ideal microalga to treat cooking cocoon wastewater and is worthy of further applications.

Contamination by heavy metals in coastal and marine environments is an increasingly serious threat to both marine ecosystems and humans. The numerous marine cultivation and industrial zones along the coast of Khanh Hoa may influence the heavy metal contamination in the seawater and marine sediments. In this study, 36 seawater and 36 marine sediment samples were collected along the coast of Khanh Hoa to evaluate the levels of eight heavy metal elements. The results indicated that heavy metal concentrations in the surface seawater at Khanh Hoa were much lower than the national technical regulatory limits. The comprehensive pollution index of the heavy metals averaged less than 1. Therefore, heavy metal pollution in the seawater along the coast of Khanh Hoa is slight. Among the eight heavy metals (Cd, Co, Cu, Cr, Mn, Ni, Pb, and Zn) analyzed in the sediments, Cu concentration in the sediment at Cam Ranh Bay is much higher than the national technical regulatory limit. Ecological risk assessment of the sediments also indicated a possible combined biological effect of Cu, Pb, and Zn at Cam Ranh. Therefore, heavy metals in the marine environment at Khanh Hoa should be monitored yearly. Decision-makers should consider the Cu content in seafood because bioaccumulation of heavy metals may occur in marine organisms.
