Authors: Mamedyarov Z. A. 
Published: August 2021

The externally induced intensification of the use of information and communication technologies in 2020 coincided with the ongoing digitalization of the world economy over the past decade. While digitalization is not a new phenomenon, the issues surrounding it are constantly changing. Before the pandemic, the discussion around digitalization mainly focused on the concepts of the fourth industrial revolution, Industry 4.0 and the Internet of Things (IoT). The pandemic brought digitalization to companies and industries that had previously been relatively backward in this respect. During the pandemic, the shift of employees to remote work using ICT technology reached an unprecedented scale and stimulated a change in consumer behavior, and the duration of the pandemic triggered a long-term process of adoption of new types of ICT goods and services.The ICT corporations were able to significantly increase their user base and use the accumulated innovation potential to bring new products and services to market. This paper examines the implications of the pandemic for the digital infrastructure and the digital economy. The pandemic has contributed to the emergence of hybrid business models that combine the features of offline and online services. The strengthening of innovative competition in the ICT sector can lead to further consolidation of the industry, which is already being noted in the semiconductor industry and the segment of ICT services. Separately, the paper examines the Russian innovation policy in the digital sphere. Also, given the inevitable growth of innovation and trade competition in the digital sphere in Russia since 2017, new directions of state support for digital companies, products and services have been created. It is shown that the main focus of innovation policy in this area in Russia remains the public services segment. At the same time, the relevant national programs face the problem of goal-setting.

Abstract
The aim of the study was to provide an in-depth characterization of the methanol-aqueous extract from the aerial parts of Gypsophila glomerata Pall. Ex Adams (Caryophyllaceae) (EGG) and to assess its protective potential on carbon tetrachloride (CCl4)-induced liver and kidney damage in male Wistar rats. Twenty-two flavonoid C-, O- and C,O--glycosides in EGG were annotated by mass spectrometry--based molecular networking; nine of them are reported in this species for the first time. Fourteen-day oral administration of EGG at a dose 200 mg kg−1 bm prevented significantly CCl4-induced liver injury, discerned by an amelioration of the markers of oxidative stress (GSH and MDA) and transaminase activity. EGG decreased the serum level of urea and creatinine as well. The observed improvement of biochemical parameters was supported by histopathological observations. The protective hepatorenal effects of EGG, rich in 2“-О-pentosyl-6-С-hexosyl-apigenin/luteolin/ methylluteolin and their acetyl- and methoxycinnamoyl-derivatives, were comparable with the effects of the positive control silymarin.

Abstract
The epidemic of the novel coronavirus disease (COVID-19) that started in 2019 has evoked an urgent demand for finding new potential therapeutic agents. In this study, we performed a molecular docking of anti-HIV drugs to refine HIV protease inhibitors and nucleotide analogues to target COVID-19. The evaluation was based on docking scores calculated by AutoDock Vina and top binding poses were analyzed. Our results suggested that lopinavir, darunavir, atazanavir, remdesivir, and tipranavir have the best binding affinity for the 3-chymotrypsin-like protease of COVID-19. The comparison of the binding sites of three drugs, namely, darunavir, atazanavir and remdesivir, showed an overlap region of the protein pocket. Our study showed a strong affinity between lopinavir, darunavir, atazanavir, tipranavir and COVID-19 protease. However, their efficacy should be confirmed by in vitro studies since there are concerns related to interference with their active sites.
Size and selected characteristics of northern pike (Esox lucius L.) commercial and angling catches in Polish inland waters over the long term
Authors: Trella Marek , Wołos Arkadiusz 
Published: August 2021

Abstract
Northern pike (Esox lucius L.) is of great importance to inland commercial and recreational fisheries in Poland. Thanks to northern pike’s substantial size, strength, the possibility of using a variety of fishing methods and techniques and various baits, and many other values, lake anglers value this species above all others. Additionally, for over a decade, northern pike has been the most widely stocked species in Polish inland waters of lakes, rivers and dam reservoirs. The aim of this work was to analyze in detail the size and characteristics of northern pike commercial fisheries and angling catches in Polish inland waters over the long term. The analyses were based on a compilation of traditional scientific papers, primarily analyses of commercial catches, and a review of the results of more than 40 years of studies on the size of northern pike angling catches. The analysis of research material indicated a steady decrease in commercial catches of this species in the years State Fisheries Enterprises (SFE) were in operation followed by relative stability in catches over the past two decades. The paper describes the methods used to estimate angling catches, namely questionnaire and catch-return (the so-called register) research. An increasing disproportion between the sizes of pike catches made with angling and commercial fishing gear was documented. Despite the problems presented in the paper related to estimating total pike catches, the analysis revealed that anglers catch eightfold more northern pike than do commercial fishers.

Abstract
The reproductive cycle of the crustacean family Portunidae on the coast of the Pacific is not well known. Therefore, the reproductive cycle and the size at first maturity of brown crab Callinectes bellicosus and its relationship with environmental factors in the El Colorado Lagoon, Ahome, Sinaloa has been determined. A total of 360 females were collected from March 2012 to March 2013. The gonads were fixed in 10% formalin, histological cuts were made by the paraffin inclusion method and the hematoxylin and eosin staining technique. The diameter of oocytes was determined by stage. The size at first maturity was estimated by a logistic model. Females showed gametogenic activity during the entire study period. The maturity period was from March to November 2012, with two spawning peaks, in September 2012 and March 2013. Maturity was inversely influenced by temperature (r = -0.4454, P < 0.05) and no influence by salinity was observed (P > 0.05). The diameter of the oocytes showed significant differences between the development stages of the gonad (P = 0.001). The size at first maturity was 11.57 cm of carapace width for females of C. bellicosus.

Understanding the Use of Social Media to Foster Student Creativity: A Systematic Literature Review
Authors: Vilarinho-Pereira Daniela Rezende , Koehler Adrie A. , de Souza Fleith Denise 
Published: August 2021

Abstract
Social media have been increasingly used by youth to communicate with peers, access information, share creations, and express themselves. As a result, educators and researchers have recognized the potential for using social media to enhance teaching and learning experiences. Some scholars have also identified a relationship between social media integration and promoting student creativity. However, as with any educational technology, using a tool, such as social media, does not automatically increase creativity. In other words, the specific methods used to integrate social media as part of a learning experience affect the tool’s influence on the learning process. Therefore, the purpose of this study was to review literature considering the use of social media in formal learning environments and examine their relationship with enhancing student creativity. We conducted a search to locate empirical studies (qualitative, quantitative, or mixed method) published between 2010 and 2020 from the Academic Search Premier, Education Full Text, Education Source, ERIC, and PsychINFO databases. In the results, we describe how social media were used for instructional purposes in the selected studies and discuss the social media affordances that lead to fostering students’ creativity. Additionally, we provide recommendations for educators interested in integrating social media into their teaching practice, specifically to boost student creativity, and we offer suggestions for future research.

Authors: Ogbonna Alban Chidiebere 
Published: August 2021

Abstract
Use of roller-compacted concrete in pavement construction is increasing. Roller compacted concrete is a zero-slump, highly compacted concrete that is placed by equipment similar to that used in asphalt pavement construction. This investigation was conducted to collect the state-of-the-art information on effects of coarse aggregate size and texture on the strength and workability of roller-compacted concrete (RCC) for pavement construction and maintenance. Concrete specimens containing cubical and rough coarse aggregate, irregular and rough coarse aggregate, angular and rough coarse aggregate, rounded/spherical and smooth coarse aggregate, and flaky/elongated and rough coarse aggregate were prepared at 1:3:3 concrete mix ratio and 0.4 water cement ratio. Laboratory testing of specimens derived from the concrete specimens showed excellent results for cubical and rough coarse aggregate, irregular and rough coarse aggregate, and angular and rough coarse aggregate. Specimens from the rounded/spherical and smooth coarse aggregate, and flaky/elongated and rough coarse aggregate performed poorly in laboratory. The study therefore recommends the use of cubical and rough coarse aggregate, and irregular and rough coarse aggregate in the production of roller-compacted concrete for pavement construction and maintenance.

Проведено теоретичний аналіз історичного становлення і розвитку домашнього насильства над жінкам як наукового поняття. Здійснено історичний зріз стосовно виникнення домашнього насильства над жінками. Охарактеризовано розвиток домашнього насильства над жінками. Констатовано, що домашнє насильство над жінками є науковим поняттям, яке потребує комплексного вирішення різними галузями, такими як: соціологія, психологія, педагогіка, філософія, психіатрія.
Описано роль релігійних канонів у формуванні домашнього насильства, які сприяли існуванню суспільних і державних утворень, установок і цінностей, констатовуючи прагнення володіти чоловіка над жінкою. Виділено основні етапи домашнього насильства: першим етапом є виникнення напруги у стосунках; наступним – сам прояв насильства; фінальним – “Медовий місяць”.
