In Vitro Rapid Regeneration of Plantlets from Shoot Tip Explants of Allamanda Cathartica L. and Characterization of Phytochemicals in Regenerants
Authors: Nisha Khanam Mehrun , Anis Mohammad
Published: March 2024

This study demonstrates a rapid, economic and efficient plantlet
regeneration protocol for an exotic ornamental and medicinal plant  Allamanda cathartica L. by using shoot tip explants. Interaction of various PGRs (mT, IAA, IBA
or NAA) and sucrose was tested in MS medium to obtain maximum shoot regeneration
from shoot tip explants. mT (3.0 µM) + NAA (0.5 µM) + 4% sucrose was found to be
an optimum combination for maximum shoot proliferation with 20.80 mean shoot
number and 7.60 cm mean shoot length after 12 weeks of culture based on 93.20%
responsive explants. Microshoots (4-5 cm) showed maximum rhizogenic response as
they produced 4.20 mean root number with 4.90 cm root length after 4 weeks of culture
on ½ MS medium when supplemented with 0.5 µM NAA. Well-developed rooted
plantlets were acclimatized successfully with a 96% survival rate. The primary
phytochemical screening of aqueous leaf extract in the regenerants revealed the
presence of proteins, carbohydrates, lipids, phenols, proteins, and saponins.
Quantification of phytochemical constituents showed that the amount of phenols was
highest, followed by lipids, proteins, carbohydrates, saponins and alkaloids in the
micropropagated plants. These phyto-constituents are known to cure numerous
ailments.

Published: March 2024

Over the past few years, there has been a tremendous global shift of
preference toward herbal medicine because of its affordability, accessibility, efficacy,
and lesser side effects. The pharmacological and healing properties of the herbs are due
to the presence of a wide array of secondary metabolites. These metabolites are
biosynthesized through defined pathways and stored in various parts of the plant, like
leaf, root, rhizome, bark, and floral parts. In recent years due to the growing realization
of the pharmaceutical properties of medicinal plants, they have been subjected to
indiscriminate exploitation. Further, the lack of agrotechnology in many cases and the
nonavailability of broad genetic diversity provide impediments to their largescale
cultivation and improvement. This situation has created a huge gap between the
demand and supply of medicinal plants all over the world. Hence, rapidly propagating
high valued medicinal plants through unconventional technologies is warranted and
will provide high dividends to farmers and the herbal industry. Further, generating
large-scale healthy, genetically uniform plants with defined chemical content will
facilitate pre-clinical and translational studies. Therefore, efforts in the development of
robust in vitro propagation systems for herbal plants can address the core concern of
their conservation and large-scale utilization. Studies on cell suspension, hairy root
culture, and genetic transformation have provided the desired impetus in metabolic
engineering and enhanced their commercial value. The present article highlights some
of these developments and provides a futuristic perspective on the subject.
Del estancamiento al crecimiento: las exportaciones colombianas de 1774 al 2000
Authors: Meisel Adolfo
Published: March 2024

La economía colombiana estuvo estancada durante la mayor parte del siglo XIX. Como resultado, el crecimiento anual de su producto interno bruto (PIB) per cápita fue de alrededor del 0,4%. En cambio, durante el siglo XX, el crecimiento anual de su PIB per cápita fue del 2,0%. Una parte importante de este resultado puede atribuirse a que las exportaciones no crecieron durante el siglo XIX –la tasa promedio anual de crecimiento de las exportaciones efectivas fue del 0,0%–, mientras que en el siglo XX crecieron a una tasa del 2,0%.
 
Sobre el tema de las exportaciones colombianas en el siglo XIX se han publicado dos estudios: McGreevey (1970) y Ocampo (2013). McGreevey utilizó como fuente para su relato histórico los registros de lo que importaban los principales socios comerciales de Colombia. Sus resultados son defectuosos debido a problemas con la información de reexportaciones y las definiciones de las unidades territoriales que utilizó. En el caso de Ocampo, aunque analizó datos oficiales publicados por el Ministerio de Hacienda de Colombia, la información considerada no incluyó estimaciones anuales, sino un índice por subperíodos ad hoc. Por tanto, no se pueden estimar las tasas de crecimiento.
En este artículo presento la serie anual real de exportaciones colombianas per cápita en los siglos XIX y XX. El uso de información anual me permitió calcular las tasas de crecimiento para diferentes subperíodos. Este estudio, por simple que sea, es un valioso aporte al estudio de la historia económica colombiana.
Anachronism or Cultural Transfer? Latin Journals in the Public Sphere of the Hungarian Kingdom in the Eighteenth and Nineteenth Centuries
Authors: Balogh Piroska
Published: March 2024

Latin journalism in Europe flourished between 1600 and 1750. However, in the peripheral regions east of the German-speaking lands, including Hungary, periodicals began to appear in greater numbers only from the early eighteenth century. By that time, Latin journalism was losing its popularity in the central regions of Europe due to the widespread establishment of the vernacular press and the standardization of native languages. Yet, the editors of the newly established periodicals in Hungary could not follow this pattern due to several reasons. One solution to their problems was to develop the Latin-language press. This paper attempts to reconceptualize the role of late Latin journalism from the perspective of specific peripheral cultural circumstances, with a special focus on the periodical genre of ‘ephemerides’. The focus of the analysis is on Ephemerides Statistico-Politicae / Posonienses (1804–38), a popular and significant nineteenth-century Latin journal, and its supplementary annexes.
The Double Resistance of the German Periodical Die Zone (1933–34) in Paris
Authors: Gucsa Magdolna
Published: March 2024

This article aims to explore the programme of the German-language anti-Nazi journal Die Zone, in which cultural criticism and political activism were inextricably intertwined. Published in Paris in 1933–34 as an exile periodical, it challenges the centre-periphery dichotomy by occupying a peripheral position with respect to the cultural and linguistic context to which they belong and wish to influence, while at the same time being able to rely on social and relational capital that would never be available to a platform belonging to a genuine (semi-)periphery. Taking into account the complexity of its positions, my investigation into Die Zone is therefore structured around three main questions. While exploring (1) the effectiveness of the journal as a platform for a community to engage in a double resistance, i.e. political action against both National Socialism and its own marginalization in French society, I equally examine (2) whether the editor-in-chief Emil Szittya could mobilize and channel the extensive network he had built in the context of the international avant-garde in the 1910s and 1920s. Finally, (3) I tackle the perception of Die Zone and those who made it by the French (general or professional) public.

Published: March 2024

Ranom dijagnozom raka dojke postiže se bolje preživljavanje i manje agresivno liječenje. Slikovne metode poput ultrazvuka, mamografije i magnetske rezonancije osnovne su metode oslikavanja dojki kojima se mogu detektirati lezije u vrlo ranoj, neinvazivnoj fazi. Kao zlatni standard u postavljanju dijagnoze koristi se patohistološka analiza tkiva, stoga su biopsije sumnjivih lezija u dojci neizostavni dio obrade. Općenito, slikovno navođena biopsija dojke potrebna je za nepalpabilne lezije, ali se preporučuje i za palpabilne lezije jer poboljšava točnost dijagnoze. Intervencije u dojci navođene ultrazvukom, mamografijom ili magnetskom rezonancijom pouzdane su metode, a postavljanje tkivnog markera nakon biopsija znak je dobre prakse. Poglavito je važno markirati lezije nakon mamografski navođene biopsije, kao i lezije manje od 5 mm jer se lezije mogu potpuno ukloniti te je tada prijeoperacijska markacija znatno otežana. Isti je princip kod neoadjuvantog liječenja kada tumorski proces može u potpunosti regredirati, stoga tkivni marker omogućuje precizno izvođenje kirurškog zahvata. Za markaciju patoloških limfnih čvorova uputno je korištenje specijalno izrađenih markera, dobre vidljivosti pod svim modalitetima oslikavanja, koji omogućuju preciznu markaciju limfnog čvora nakon provedenog neoadjuvantnog liječenja. Prijeoperacijska lokalizacija nepalpabilnih lezija koristi se za optimizaciju kirurške ekscizije radi očuvanja negativnih rubova bez žrtvovanja normalnog tkiva. Ovaj pregledni rad opisuje i minimalno invazivne tehnike, kao što su termalne ablacije, krioablacija i visokofrekventni fokusirani ultrazvuk kao alternativa kirurškoj eksciziji, s ciljem smanjenja broja komplikacija, boljeg kozmetičkog rezultata i skraćenog boravka u bolnici. Ovaj pregledni rad opisuje spektar slikovno navođenih intervencija koje se izvode u Kliničkom bolničkom centru u Rijeci.

Authors: Gracheva N. A. , Polishchuk O. A. , Pylaykina A. V.
Published: March 2024

Relevance. Startups are an integral part of the modern economy and business, and their creation and development represent an important contribution to the economic growth and innovative development of the country. At the same time, the startup system in Russia has not yet been fully developed ‒ there are problems with their number, successful activities, and financing of startups. There are many sources of financing for startups, but it is often difficult for young entrepreneurs to find the necessary resources to implement their business idea. This may lead to the inability to launch a startup or to difficulties in its development. Therefore, studying the issues of financial support for a startup is relevant for many people starting their own business, as well as for investors, venture funds and large companies that can provide significant support for startup entrepreneurs.

   The purpose of the study is to analyze and evaluate the problems of growth, development and financing of startups.

   Objectives: analyze the startup business market; consider niches of the startup market and assess its growth trends; identify sources, main directions and problems of financing startups.

   Methodology. During the scientific research, empirical, theoretical, statistical and graphical methods were used.

   Results. The theoretical aspects of startup business were studied, the startup market was analyzed, the main sources of startup financing were identified, as well as the associated problems of growth and financing of startup business.

   Conclusions. The startup system has not yet been fully developed in Russia. Russia is still losing in terms of the total number of startups and the number of startups per 1 million people. The business areas in which startup developers operate are very diverse. The creation and successful development of startups depends on many factors, including financial security. The article discusses the problems of financing startups. The viability of startup developments in the Russian Federation in recent years has been strongly influenced by the COVID-19 pandemic and the sanctions imposed against the country. However, the main factor remains the lack of financial resources.
Information and Environmental Media Hygiene as an Object of Sociological Analysis
Authors: Belkina V. A.
Published: March 2024

Relevance. The widespread use of modern information and communication technologies, in particular, social Internet media, forms a special space (media ecosystem), which has a significant impact on the formation of public opinion, values and behavior of people. Particularly significant in the realities of expanding the boundaries of the media space of the culture of modern society, in the context of human interaction and the media ecosystem, is the researchers' appeal to the problem of determining the basic principles of the information and environmental media hygiene, considered as the ability of society to resist the destructive influence of media discourse in the post-truth era and related to the study of the influence of the media on mental and moral health of a person.

   The purpose of this work is a sociological analysis of the information and environmental media environment as one of the directions of countering the risks and dangers of the modern media environment.

   Objectives: disclosure of the essence of the main risks and dangers of the modern media environment; analysis of the relationship between the concepts of "information hygiene" and "information and environmental media hygiene"; definition of the basic principles of information and environmental media hygiene both from the side of modern social media (primarily Internet communication) and from the side of modern active users of the media environment (both media consumers and media producers).

   Methodology. The article uses such general scientific methods as comparative analysis, synthesis, abstraction and generalization. The research is based on the basic principles of a systematic and structural-functional approach. An ecological approach to understanding the media space was chosen as the main theoretical and methodological guideline.

   Results. The paper presents the results of theoretical and methodological analysis of the phenomenon of information and environmental media hygiene. The basic principles of the information and environmental media hygiene are defined and formulated both on the part of modern social media (primarily Internet communication media) and on the part of modern active users of the media environment (both media consumers and media producers).

   Conclusions. The modern media space and the developed media environment, in addition to providing various benefits and privileges to meet the information needs of media users, also carries large-scale risks and dangers, which, first of all, include infodemia and infoxification. Due to the fact that these negative phenomena have serious consequences for society, it becomes especially important to define and develop the principles of information and environmental media hygiene, which must be observed both by modern social media (primarily Internet communication) and by active users of the media environment (both media consumers and media producers).

   Conclusions. Partnerships have proven to be an important factor in developed and emerging markets, however, in the case of developed markets, this strategic step benefits in quantitative terms, and in the case of emerging markets, both in qualitative terms (localization of content) and in quantitative terms, the growth in the number of users. The findings and results of the study will be useful to existing streaming services, startups, venture investors and government agencies regulating this area.
Development of the Far Eastern Territories of Russia: from the Origins to Modern Realities
Authors: Abramov A. P. , Suprun A. Yu. , Pashutko D. S.
Published: March 2024

Relevance. In the conditions of the new world order, issues of state migration policy are of particular importance. The rapid development of the Far Eastern Federal District in the 21st century is determined by “absolute priority”. Therefore, the problems and prospects for technological and infrastructural development of the Far East require scientific understanding and social correction from all levels of state and municipal government. As prospects for minimizing the consequences of population outflow, a set of management measures is proposed, primarily at the federal level, which involves: providing a package of social preferences to all socio-demographic groups of residents of the Far Eastern Federal District; attracting human resources within the framework of the annually held competition “Leaders of Russia” and implementing in-depth scientific research on all socially significant projects.

   The purpose is to identify promising areas of managerial influence to minimize the outflow of population from the Far Eastern territories of modern Russia.

   Objectives: characterize the historical retrospective of the development of the Far Eastern territories; reveal cause-and-effect relationships, conditions and factors of population outflow; outline directions for minimizing negative migration consequences.

   Methodology. Research procedures are based on a synthesis of theoretical principles of the sociology of management and economics, using general scientific methods of comparison, analysis and synthesis.

   Results. A set of quantitative and qualitative sociological measurements was carried out, which made it possible to determine the "pain points" of migration policy in the Far East and the prospects for their resolution.

   Conclusions. Stratification differences between Russian regions in terms of basic socio-economic indicators require the federal level of government to take specific measures to minimize their consequences. Underfunding of technological and infrastructure projects in the Far Eastern territories leads to fragmentation of their implementation. Deep scientific expertise and public approval are necessary when developing federal and regional development programs for the Far Eastern territories.

Authors: Kamensky E. G. , Mayakova A. V. , Ogurtsova A. Y. , Huseynov M. A.
Published: March 2024

Relevance. The "state-science-business" model has firmly entered the practical sphere of human and social life as a signifier of many socio-economic processes. It is a systematic integrated approach to the consideration of problems exclusively applied areas that will allow them to be solved in the most effective way and in the shortest possible time. The economic sphere has always been considered by the state as one of the priorities, since a steadily developing economy provides ample opportunities for the development of civil society. Over the past few years, the President and the Government of Russia have outlined clear guidelines for the development of the economy, one of which is the modernization of the industrial complex of the state through the inclusion of the state and scientific and technological block in the industrial system.

   The purpose of this study is to review and analyze the model of interaction "state – science – business" within the framework of Russia's economic development and the long-term plans established by the President of the Russian Federation concerning the modernization of the industrial complex.

   Objectives: to analyze the international experience of the development of the industrial complex; to consider the features of the formation and functioning of the domestic industrial complex; to study the current state and assess the prospects for the development of the economy and production on the example of the military-industrial complex of Russia.

   Methodology. The study was carried out on the basis of the general provisions of the system theory and interinstitutional and transinstitutional communication using the system-structural method.

   Results. In the conditions of the established priorities of economic development at the highest level, it is necessary to: develop internal and external R&D; generate the creation of a new type of university, the ecosystem of which moderates ideas and projects requested by society and the state, releasing them into the real sector of the economy for production and economic development; introduce the university (science) into the business community; form engineering andscientific personnel potential.

   Conclusions. For the economic development of the country, it is necessary to strengthen the "state-science-business" relationships not only from the perspective of the industrial complex, but also scientific and educational platforms, including through the development of external R&D and their opening on the basis of higher educational institutions.
Image of the Future: Methodological Foundations
Authors: Makaryev I. V.
Published: March 2024

Relevance. This article analyzes the categories "image" and "image of the future" as a fundamental for various concepts of the image of the future. The relevance of this article is dictated by the radical changes taking place in Russia and in the world, which have called into question the existence of previous socio-economic and political systems.

   The purpose of the study is to analyze the methodological foundations of the image of the future.

   Objectives: to consider the concepts of "image" and "image of the future", based on the etymology of the words themselves and their relationship with other words and phrases: "model" (of the future), "picture" (of the future), "concept" (of the future); show the differences and similarities of the concept of "image" in psychology, philosophy and fiction; reveal the connection between the image of the future and the memory of the past.

   Methodology. The methodological basis of the article is the historical-critical method developed in the German (R. Koselleck) and English (K. Skinner, J. A. Pocock) schools of the history of concepts.

   Results. The relationship between the concept of "image" and the concepts of "model", "picture", and "concept" has been studied. It has been proven that it is the concept of "image" that is most suitable for connection with the concept of "future", because in the phrase "image of the future" two sides are inextricably linked: subjective and objective, which makes it possible to take into account both fantasies and real projects about the future. It is shown that the subject of the image of the future is not so much an individual as a certain community of people and that the image itself is between them, in the interaction that exists between people in society.

   Conclusions. The conducted methodological analysis creates a philosophical basis for further research, both for subsequent methodological research and for various analyzes of specific aspects of the image of the future of Russia and the world as a whole.

Efficient Algorithm Set Forming for the Computing Resources Distribution in Heterogeneous Dynamic Computational Environments Based on the Ontology Usage
Authors: Klimenko A. B. , Alieva E. M. , Salnikov A. Y.
Published: March 2024

Purpose of research. The purpose of this research is to develop an ontology structure as the basis of a database/knowledge base for selecting effective metaheuristic algorithms for solving the problem of load distribution in heterogeneous distributed dynamic computing environments, taking into account the overhead of data transmission over the network.

Methods. The main scientific methods used in this study are domain analysis, methods for constructing subject ontologies, numerical optimization methods and computer modeling.

Since the literature does not present resource allocation planning models that would take into account geographic distribution, the presence of intermediate data transmission routes, the dynamics of topologies and load, as well as system heterogeneity in terms of criteria for assessing the quality of load distribution, this article proposes a new model that takes into account these features. The complexity of solving a planning problem becomes one of the variable parameters, which has a significant impact on the planning result: with a decrease in the complexity of calculations, the result deteriorates accordingly. Therefore, a greedy strategy is proposed as a solution method: from the optimization methods to be considered, select the least labor-intensive one that would allow obtaining the best result in the allotted time. Test runs of simulated annealing algorithms demonstrate different effectiveness under different initial conditions of the problem; therefore, it is advisable for selected classes of problems to choose algorithms that are effective in terms of solution quality and labor intensity.

Results. The result of the study is the structure of the ontology of effective algorithms. Also, the results are instances of simulated annealing algorithms and tasks included in the ontology, related by the “efficiency” relation.

Conclusion. This article proposes the structure of an ontology of effective optimization algorithms and an approach to solving the problem of distributing the computational load, taking into account the complexity of the distribution procedure through the “greedy” selection of the most effective optimization algorithms.

Purpose of research. The aim of the study is a comparative analysis of the stress-strain states of welded joints during welding of saddle branches to existing gas pipelines under normal conditions using standard technology and low temperatures using the proposed technology.

Methods. To achieve the goal, a numerical implementation of the mathematical model of the thermoelastic state by the finite element method in the Python programming environment using the Fenics computing package was performed. The computational grid was built using the GMSH program. Visualization of the obtained results was implemented using the Paraview package.

Results. On the basis of computational experiments of welding a saddle branch to an existing gas pipeline at permissible and low ambient temperatures, the dynamics of the temperature fields, stresses and strains in the heataffected zone are almost identical.

Conclusion. The calculation results showed that when welding saddle branches to polyethylene pipes of existing gas pipelines at low temperatures using the proposed technology, the main physical and mechanical processes will proceed as in welding under normal conditions and provide the necessary strength.

Published: March 2024

Background

Adult day services (ADS) provide community-based health care for older adults with complex chronic conditions but rely on outdated methods for communicating users’ health information with providers. CareMOBI, a novel mobile health (mHealth) app, was developed to address the need for a technological platform to improve bidirectional information exchange and communication between the ADS setting and providers.

Objective

This study aims to examine the feasibility and acceptability of CareMOBI in the ADS setting.

Methods

A concurrent-triangulation mixed methods design was used, and participants were client-facing ADS staff members, including direct care workers (paid caregivers), nurses, and social workers. Interviews were conducted to describe barriers and facilitators to the adoption of the CareMOBI app. The acceptability of the app was measured using an adapted version of the Technology Acceptance Model questionnaire. Data were integrated into 4 themes as anchors of an informational matrix: ease of use, clinical value, fit within workflow, and likelihood of adoption.

Results

A mix of ADS staff (N=22) participated in the study. Participants reported high levels of acceptability across the 4 domains. Qualitative findings corroborated the questionnaire results; participants viewed the app as useful and were likely to implement CareMOBI in their practice. However, participants expressed a need for proper training and technical support throughout the implementation process.

Conclusions

The CareMOBI app has the potential to improve care management in the ADS setting by promoting effective communication through an easy-to-use and portable method. While the integration of CareMOBI is acceptable and feasible, developing role-specific training modules and technical assistance programs is imperative for successful implementation within the ADS setting.
Intangible Cultural Heritage Awareness Survey among Residents in Zhangzhou City: A Perspective on Cultural Heritage Security
Authors: Liu Chang
Published: March 2024

This study, taking the perspective of cultural heritage security, conducted a survey among residents of Zhangzhou on their awareness of intangible cultural heritage (ICH) using questionnaires. The findings reveal that residents of Zhangzhou exhibit relatively high awareness of ICH in folk customs, fine arts, and drama, while awareness is comparatively lower in music and folk performing arts. The primary channels of awareness include new media (66.6%), traditional media (53.3%), and family and friends (51.5%). Traditional drama (60.6%) and traditional craftsmanship (57.3%) emerge as the most prominent areas of interest among ICH projects. The majority supports heritage protection through live demonstrations and multimedia materials, emphasizing challenges such as insufficient government support, inadequate media coverage, and a shortage of heritage inheritors. The government is perceived as the primary responsible entity (32.9%), while heritage inheritors are considered the main custodians (36.2%). Regarding consumption related to ICH, most respondents adopt a cautious stance, with 59.8% indicating an annual spending of less than 500 yuan. In conclusion, the survey calls for collective efforts within society to address key issues in heritage protection, ensuring its sustainable inheritance and development.
Palatial Conspiracy in Shakespeare’s Macbeth and Abu Zafar’s Siraj-ud-Daulah: A Comparative Study
Authors: Afroz Sadia
Published: March 2024

A conspiracy is defined in criminal law as an agreement between two or more people to commit a crime in the future. It is a nefarious, illegal, treacherous, or covert scheme devised by two or more people in secret. Instead of explaining an occurrence or circumstance, a conspiracy theory suggests that it is the plan of evil and powerful people, generally with political motives. The phrase ‘conspiracy theory,’ with its pejorative connotation, suggests that people who believe in conspiracies are motivated by bias or a lack of proof to back up their assertions. For this purpose, this study would like to examine Shakespeare’s Macbeth and Sikandar Abu Jafar’s Siraj-ud-Daulah to foster the real picture of palatial conspiracy historically. It would like to investigate some powerful male and female characters of the two well-familiar historical plays, including Nawab Siraj-ud-Daulah Ghaseti Begum, and Mir Jafar on one hand, as well as Macbeth and Lady Macbeth on the other hand. It aims to explore the historical contexts to expose the source on which the stories of the plays have been grounded. Finally, this study aims to look at the comparative discussion of the protagonists in light of writers’ treatment of palatial conspiracy of the age, art of characterization, and plot construction. Thus, it aims to create a novel dimension of English literature by highlighting the historical concerns of sixteenth-century England and the eighteenth-century Indian subcontinent, respectively.
