Published: December 2024

Integrated plant nutrient management (IPNM) strategies improve the income of growers. Therefore, the objective of this study was to evaluate the growth and yield of bush beans (Phaseolus vulgaris L.) of the ‘Bacatá’ cultivar under different nutrition management strategies using different chemical fertilizer sources (edaphic and foliar) and compost in three high-Andean environments in Colombia. The IPNM treatments were set up in high- and low-rainfall zones (Gachalá vs. Guachetá) and in a greenhouse. The IPNM comprised plants without nutrients (AC); full dose NPK (EC); a mixture of compost based on wastes (20%), NPK (80%), and foliar fertilizer (GCFF); a mixture of compost based on waste (20%) and NPK (80%)(GC); a mixture of commercial compost (20%), NPK (80%), and foliar fertilizer (CCFF); and a mixture of commercial compost (20%) and NPK (80%) (CC). The results showed that the zones with higher rainfall (Gachalá) generally had a higher relative and absolute growth rate than the low rainfall zone (Gachetá) and greenhouse at different sample points. The IPNM treatments with a mixture of compost compounds showed agronomic efficiency similar to that of plants treated with chemical fertilizers only. Plants without any nutrient application showed the lowest yield parameters, reaching a production close to 1100 kg ha-1, compared to the other nutrient application treatments that reached a production close to 1600 kg ha-1. These results indicate that IPNM treatment is an important tool for improving the productivity of common bush beans grown in Andean agro-ecosystems.

Published: December 2024

Cotton aphid is the most common and harmful insect in the process of cotton growth and development, and it is the most serious pest that restricts the high yield and high quality of cotton in China and even in the world. The field-scale experiments were conducted for two years to estimate the population of cotton aphids model on cotton leaves using remote sensing. Hyperspectral data from single leaves and aphid populations were obtained at different growth stages of various cotton varieties. Preprocessing techniques including savitzky-golay (SG), first derivative (FD), second derivative (SD), logarithm transformation (LG), and reciprocal transformation (RG) were applied to the original spectral data. The successive projections algorithm (SPA) combined with the Pearson correlation coefficient (Pearson) method were used to construct three types of hyperspectral monitoring models: linear regression (LR), Extreme gradient boosting (XGBoost), and partial least squares regression (PLSR). Results indicated that LG significantly improved model accuracy, while SPA effectively reduced the number of bands required for analysis. Among the three models constructed using selected feature bands, the XGBoost model outperforms LR and PLSR models in terms of prediction accuracy. LG-Person-XGBoost identified ten feature bands with a coefficient of determination (R2), root mean square error (RMSE), and relative percent deviation (RPD) values reaching 0.76, 65.74 heads/leaf, and 0.91 respectively for the modeling set; whereas predicted R2, RMSE, and RPD values were found to be 0.36, 57.62 heads/leaf, and 0.99 respectively. LG-SPA-XGBoost achieved superior prediction accuracy by selecting eight feature bands with R2, RMSE, and RPD values reaching 0.87, 46.7 heads/leaf, and 1.43 respectively for the modeling set; whereas predicted R2, RMSE, and RPD values were found to be 0.77, 42.66 heads/leaf, and 1.27 respectively. This indicates that the hyperspectral remote sensing model can be used to estimate the population of cotton aphids on cotton leaves based on the selection of feature bands providing are reference for the nondestructive monitoring of cotton aphids in cotton fields and offering a significant supplement to the traditional methods of crop pest quantity monitoring.

Published: December 2024

Saline water irrigation presents a significant challenge in agriculture, especially in regions with water scarcity and soil salinity. Lilies are economically significant ornamental plants renowned for their aesthetic value and commercial importance. This study aims to evaluate the effects of saline water irrigation on lily anatomy, physiology, and postharvest flower quality. Three NaCl salinity levels with varying electrical conductivities (EC) (control 0.65, 3, and 6 dS m-1) were applied to three hybrid lilies (Lilium × elegans): fragrant Orienpet (‘Maytime’, white), non-fragrant Longiflorum-Asiatic (‘Pavia’, yellow), and ‘Fangio’ (pink).
Overall, moderate salinity (3 dS m-1) significantly altered lily anatomy and physiology, resulting in reduced postharvest quality, particularly evident in leaf greenness, flower size, quantity, and vase life. Exposure of plants to higher salinity levels (6 dS m-1) resulted in significant reductions in leaf area (40%), plant height (21%), stem diameter (15%), chlorophyll content (29%), and photosynthesis (Pn) (20%) compared to the control. Analysis revealed thinner epidermal cell and parenchyma tissues, along with decreased ground tissue thickness, contributing to reduced stem diameter. Reduced photosynthesis in salt-stressed lilies was attributed to significant declines in stomatal conductance (gs) (72-80%) and abaxial stomatal index (69%). High salinity levels also led to decreased flower diameter, size, number of flowers per stem, and vase life. However, irrigation with saline water at 6 dS m-1 enhanced certain color attributes, including petal redness (a*) in ‘Fangio’ and yellow hue (b*) in both ‘Fangio’ and ‘Pavia’ hybrids, along with increased colorfulness/saturation levels (C*) across all cultivars. In conclusion, this study offers valuable insights into identifying anatomical stress indicators that elucidate physiological responses. These findings could contribute significantly to the development of effective stress mitigation strategies for lily cultivation, particularly in water-scarce and saline environments.

Published: December 2024

Tambourissa comorensis (TC) is a member of the Monimiaceae family endemic to the Comoros Islands where it is regarded as a medicinal plant. In this study, the fatty acids (FA) composition and profile of air-dried powdered fruits of TC were examined by GC-MS. Based on the results, four major common fatty acids were tentatively identified as well as five other minor fatty acids. The analysis revealed the presence of both saturated and unsaturated fatty acids. The dried fruits exhibited oleic acid (30.64%) and linoleic acid (29.13%) as the dominant fatty acids, while palmitic acid (17.95%) and stearic acid (4.25%) were the main saturated FA identified. These fatty acids were isolated as pure compounds, with the exception of stearic acid, which was obtained as a mixture from crude lipid n-hexane extract fractionation on a silica gel column chromatography and identified in their free form by 2D-1H-NMR (300 MHz), 13C-NMR (75 MHz) and infrared (IR) spectroscopies. The average oil content in dried powdered fruits of T. comorensis species was estimated to be approximately 8%, with saturated fatty acids, monounsaturated, and polyunsaturated ones constituting about 22.67%, 32.07%, and 29.13%, respectively. T. comorensis fruits were found to be rich in health-promoting compounds, suggesting potential applications in the food, cosmetic, or pharmaceutical industries. This study is the first to profile the fatty acids in T. comorensis fruits, laying foundations for further exploration into their nutritional and therapeutic properties, as well as their potential roles in regional biodiversity and chemodiversity.
Investigating rhizosphere dynamics and plant-microbe interactions to alleviate environmental stress
Authors: AL-KHAYRI Jameel M. , KHAN Tahir
Published: December 2024

Soil acts as a crucial reservoir for both nutrients and microorganisms, hosting a wide range of microbial communities essential for ecosystem health. Particularly noteworthy are the interactions between plants and these microbes in the rhizosphere, as they actively contribute to sustaining plant well-being and fortifying plants against environmental pressures. Challenges, such as drought and salinity, pose significant threats to agricultural output and overall plant development. Therefore, it is imperative to explore the intricate mechanisms of stress responses to develop strategies to bolster plant resilience. Plant growth-promoting rhizobacteria (PGPR) offer a promising avenue for alleviating stress-induced damage in plants. Recent progress in the understanding of drought stress has shed light on the physiological and biochemical reactions within plants, emphasizing the critical role of abscisic acid (ABA) in stress mitigation. Similarly, advancements in research on salinity tolerance have elucidated the functions of ion transporters and stress signaling proteins. PGPRs play a crucial role in enhancing plant stress resilience through various mechanisms, including the regulation of ethylene levels, enhancement of nutrient absorption, and synthesis of hormones and enzymes. Utilizing the synergistic potential of plant-microbial interactions presents a promising strategy for tackling salinity and drought challenges in agriculture. Furthermore, PGPRs are instrumental in mitigating the effects of organic pollutants and heavy metals via mechanisms such as ACC deaminase activity. Innovative approaches, such as constructed wetland systems, leverage plant-microbial interactions to enhance water quality by purging pollutants.

Published: December 2024

ABSTRACT BACKGROUND: The Kerlan-Jobe Orthopedic Clinic (KJOC) Shoulder and Elbow Score is commonly used to assess the functional status of athletes with conditions affecting the shoulder and elbow. However, a Brazilian Portuguese version of the KJOC questionnaire is currently unavailable. OBJECTIVES: This study aimed to develop a Brazilian Portuguese version of the KJOC questionnaire. DESIGN AND SETTING: This translation and cultural adaptation study was conducted at the Federal University of Paraíba, Brazil. METHODS: The procedures adopted in this study followed guidelines recommending translation by two independent translators, synthesis of the translations, back-translation performed by two native English-speaking translators, analysis by an expert committee, and pre-testing. The Portuguese version was tested with 32 athletes to assess their understanding of the assessment tool. Items were deemed adequate if they were understood by at least 90% of the athletes. RESULTS: The terms and expressions of some original items were modified to achieve better comprehensibility in the Brazilian context. No further modifications were necessary after the pre-test; all terms were comprehensible to over 90% of athletes. CONCLUSION: The translation and cultural adaptation of the KJOC questionnaire into Portuguese were completed, resulting in a Brazilian version of the scale. Further studies are needed to evaluate the reliability and validity of this scale.

Published: December 2024

ABSTRACT BACKGROUND: Temporomandibular disorders (TMD) are a major cause of non-dental pain in the oral and facial regions. OBJECTIVE: This study aimed to determine the prevalence and severity of TMD and anxiety among academics and to investigate the relationship between TMD and its associated factors. DESIGN AND SETTING: This cross-sectional study included a sample of 295 academics undertaking health courses at a university in Brazil. METHODS: The Simplified Anamnesis Index and Beck Anxiety Inventory were used to evaluate TMD and assess anxiety, respectively. Data were statistically analyzed using relative and absolute frequencies of variables. In the bivariate analysis, Pearson’s chi-square test was used, and in the multivariate analysis, raw and adjusted binary logistic regressions were used to obtain the odds ratio (OR) and respective 95% confidence intervals. Statistical significance was set at P < 0.05. RESULTS: The average age of academics was 22.95 (standard deviation ± 6.14) years, predominantly comprising women (82.7%), whites (90.8%), and singles (86.6%). The findings revealed that 81.2% of academics had TMD and 50.5% exhibited symptoms of anxiety. Academics with anxiety were three times more likely to have TMD (OR = 3.6) than those without anxiety. CONCLUSION: A significant association between anxiety and TMD was observed in academics. The prevalence of TMD was high, with academics with anxiety having a high likely to develop TMD. These findings highlight the importance of addressing mental health concerns in addition to physical health, as they are often related.

Abstract The present study aimed to replace plaster concentrations with cellulose micro/nanofibrils (CMF/CNF), evaluating the physical and mechanical properties of the nanocomposites. To make the nanocomposites, the plaster mass was replaced by levels of 0.5; 1; 1.5, and 2% (m/m) CMF/CNF. The nanocomposites were produced in dimensions of 40 x 40 x 160 mm. They were evaluated at 28 days through apparent density, water absorption, bending strength, compression strength, and microstructural analysis of the surface of the nanocomposites. The research results indicated an increase in apparent density and a decrease in water absorption for the nanocomposite with 0.5% CMF/CNF. The mechanical properties showed equivalent values for bending strength and increased compressive strength of the nanocomposites with 0.5% CMF/CNF compared to the control. The results found present an alternative trait to produce plaster, aiming to value CMF/CNF and to promote the sustainability of the civil construction sector.

Authors: OGASAWARA Naruaki
Published: December 2024

ABSTRACT Background: This study aims to analyze the co-authorship network in Gastroenterology research, focusing on publications from 2000 to 2023, to understand the collaborative relationships among researchers and identify key contributors in the field. Methods: Using data from the Web of Science (WoS), I examined 18,855 Gastroenterology-related articles published between 2000 and 2023. The analysis was conducted using Python within the PyCharm environment. I assessed the network at both macro and micro levels. Macro-level indicators included network density, clustering coefficient, components, and average path length. Micro-level indicators included degree centrality, closeness centrality, and betweenness centrality, which helped identify influential researchers and research groups. Results: The analysis revealed an evolution from a fragmented and sparsely connected network in the early 2000s to a more interconnected structure in recent years. Despite the overall increase in network density and clustering, full integration was not achieved, with many researchers remaining in isolated clusters. Key researchers such as Gasbarrini G., Vandenplas Y., and Hassan C. were identified as central figures within the network, playing crucial roles in fostering collaboration. Conclusion: The study highlights the ongoing development of collaborative networks in Gastroenterology research, identifying influential researchers and groups that drive advancements in the field. The findings provide valuable insights for enhancing future research collaborations, particularly in areas where Japan excels, such as endoscopic technology.

Published: December 2024

Silvopastoral systems are a good alternative for the recovery of degraded pastures. The objective of this study was to evaluate soil fertility, carbon and nitrogen stocks, the contribution of trees to carbon formation in the soil, and biological nitrogen fixation in silvopastoral systems in southern Espírito Santo. The experiment to evaluate the silvopastoral systems (SSP) was established in the municipality of Jerônimo Monteiro, ES, Brazil, with 5 treatments: Past: Pasture in monoculture; Eucal: Eucalyptus in monoculture; PE: Pasture and Eucalyptus in a Silvopastoral System; PEL: Pasture, Eucalyptus, and Leucaena in a Silvopastoral System; PA: Pasture and Araribá in a Silvopastoral System. Soil fertility, carbon and nitrogen stocks in the soil, the contribution of trees to carbon formation in the soil, and biological nitrogen fixation were analyzed. The treatments Past and PA showed the highest nutrient levels in the soil, attributed to low biomass absorption and composition above the soil in relation to the systems Eucal, PE, and PEL. Total organic carbon and total nitrogen levels tended to increase over time, while phosphorus, potassium, and sulfur showed a decrease in soil content. Carbon and nitrogen stocks in the soil did not show significant increases after 36 months of establishment in the silvopastoral systems. Only the Past treatment showed a higher nitrogen stock considering the depth up to 40 cm. Although no differences were found in the carbon and nitrogen stocks in the studied systems, a change in the surface soil (up to 5 cm) from a grass-derived C source to a tree-derived C source was observed in the Eucal and PE treatments. This was not observed in the nitrogen stock, where biological nitrogen fixation by legumes did not promote an increase in this nutrient in the soil.

Este trabalho de revisão de literatura e contexto educacional visa abordar e esclarecer esses problemas, além de defender uma geoalfabetização focada nas práticas espaciais e nas interações pedagógicas, coadunadas ao atual contexto ambiental e social, que exige uma educação voltada ao desenvolvimento sustentável e à promoção de mudanças éticas e de valores em nossa relação com a natureza e o mundo social.
What Time is it? Whose Time is it? Greenwich Time, Local Time and the Quest For 'punctuality' in Wales in the Late Nineteenth Century
Authors: Baker Robert
Published: December 2024

The social discipline of time-keeping permeated many aspects of life in Wales during the nineteenth century as 'punctuality' assumed a moral imperative regulated by clocks. From 1852 the South Wales Railway adopted a single time zone decided at Greenwich Observatory which simplified
railway timetables but conflicted with local time. Achieving uniformity in 'Greenwich Time' communicated through the electric telegraph proved elusive and multiple 'times' co-existed across Wales. Chiming tower clocks broadcast time locally amidst a proliferation of personal time-pieces which
reflected the obsession with punctuality, but uniform time and the popularity of 'Westminster' clocks suggested a closer Welsh alignment with the 'British' nation.
The Anti-jewish Riots of 1911
Authors: Douglas Robin
Published: December 2024

The south Wales anti-Jewish riots of August 1911 have been viewed from various different perspectives over the years, from pop culture to academic polemic. They amounted to the first large-scale episode of antisemitic violence in modern British history. Now seems an appropriate time
to look at the riots again. An examination of contemporary press evidence shows that they were the product of multiple causes. They arose out of the interplay of several mutually reinforcing factors: antisemitism and economic hardship; local problems and broader national discontents. If the
riots were multicausal, they were also unexpected. The various causal factors came together remarkably quickly to produce an outbreak of violent disorder.

Medieval and Early Modern European, African and Asian ivories seen through the Data Lens
Authors: Dressen Angela
Published: December 2024

Ivories of different natures are one of the oldest materials of artistic expression, and they have been used widely through space and time. The purpose of this article is twofold: on the one hand, to offer a data driven analysis of Medieval and Early Modern ivories in Europe, Africa and Asia (ca. 1000 to 1600); on the other hand, to offer a critical perspective on the proposed query method itself. Nine museums with 2123 objects have been chosen for this analysis, based on the availability of a query endpoint. The proposed method has clear advantages and disadvantages. To the advantages belong the possibility of researching through several museum holdings at the same time (once the dataset is modelled), to query museum object data on view and on deposit all together, to be potentially able to provide insights into a given category from a very broad perspective, but also to search for unusual objects. To the disadvantages belong the fact that data is changeable, and that the selection of the museums is driven by the availability of a query structure. Therefore, the choice of the museums is also problematic, if one wants to address an international comparison. Furthermore, each museum offered data only in specific fields, which adds complexity to an overall query.
Algorithm and Software for Monozygotic Twins Recognizing
Authors:   Perm National Research Polytechnic University, Lipin Yuriy N.
Published: December 2024

The problem of face recognition of monozygotic twins is very important and difficult to solve. Existing face recognition software products for this purpose in most cases fail to cope with this task. In this paper, we propose an algorithm for face recognition of monozygotic twins based on natural and artificially created facial asymmetry using Fourier transform. The program implementing the proposed algorithm creates two images from the left and right halves of the original photo of the face of the first twin and another image as the average of the two created. Based on the obtained four images, a vector of 28 classifier values is created for comparison. Similarly, a second vector is created based on the images of the second twin. When comparing the values of the two vectors, the invisible effect of the asymmetry of the twins' faces is triggered, allowing to distinguish them.

The article presents an analysis of modern students’ self-presentation issues in virtual communication. The «Self-image» of students was studied using the following methods: a questionnaire survey, the questionnaire «Level of Subjective Control», the Twenty Statements Test «Who am I?» by M. Kuhn and T. McPartland, content analysis of the respondents’ personal accounts on social media. The study has shown that in 100 % of cases modern students use social media for the purposes of virtual communication, receiving news, creative self-realization, and entertainment, while spending an average of 2–3 hours a day online. More than half of the respondents state their ability to realize their personal potential without the help of virtual space, indicating that the impact of social networks on their real life and behavior is minimal. The general internality indicator shows the predominance of respondents with an internal locus of control. The content analysis of the respondents’ personal accounts in social networks was based on the study of conceptual components such as information about oneself, obscene language, writing style, nickname and avatar, conflicts and manifestations of aggression, additional accounts, subscriptions, posts, personal notes. The analysis of young people’s self-representations identified the following conceptual blocks of statements that highlight the significant focuses of self-representations of the experiment participants: «The Social Self», «The Acting Self», «The Perspective Self», «The Reflective Self», «The Communicative Self», «The Physical Self», «The Material Self», «The Virtual Self», with «The Reflective Self» category dominating. Virtual space today is an environment of educational, professional, and communicative activities in which modern students are actively integrated, demonstrating a multifactorial «Self-image». The consideration of its nature and components determines the success of virtual interaction among all participants of the educational process.

In case of degenerative tissue changes and injuries of the femoral head, surface endoprosthetics is used. When installing this type of implant, two types of fixation are used to secure its pin: cemented and cementless. In case of cemented fixation, the thickness of the cement layer can significantly affect the mechanical behavior of the proximal femur, ossification processes, and the risk of aseptic loosening. To study the effect of cement thickness on the processes of osseointegration of the endoprosthesis, computer modeling of the mechanical behavior of a three-dimensional model sample of the proximal femur with a surface endoprosthesis under physiological loads was carried out. As a result of the analysis of the modeling data from the standpoint of mechanobiological principles, the optimal thickness of the cement layer was established to be about 700 μm.
Women in the fight against famine in Kazan Province in 1905–1907
Authors:   Kazan Federal University, Fedotova Anastasiya Ju.
Published: December 2024

In 1905, in many provinces of the Russian Empire there was a crop failure, which later became the cause of famine of 1905–1907. Kazan Province was among the regions affected by a crop failure. Already in late 1905 – early 1906, first charitable organizations appeared, whose goal was to help the starving population of the Kazan Province. These organizations were created by women, or they took an active part in their work. As a result, the article is dedicated to women's charity in the Kazan Province during the period of harvest failure and famine of 1905–1907.
The study is based on the materials from the collections of the State Archive of the Republic of Tatarstan (GART), the Department of Manuscripts and Rare Books of the N.I. Lobachevsky Scientific Library of Kazan Federal University (ORRC NBL KFU), the Works of the Imperial Free Economic Society, the reports of the Kazan Provincial Land Administration on charitable assistance to the population of Kazan Province affected by the 1906 crop failure, etc. Some of the materials were introduced into scientific circulation for the first time.
Thanks to published and archival materials, the circle of organizations in which women worked, their approximate number, social and professional composition was identified, and a list of women was formed. Thus, the very first organization in Kazan Province was the Committee for Public Assistance to the starving (later the Kazan branch of the Committee for Assistance to the starving at the Imperial Free Economic Society). This organization was created by the Kazan noblewoman N.P. Kupriyanova, but its composition was mixed. Almost exclusively women's organizations were the "University circle of ladies, canteens and bakeries for the starving of Kazan Province" at Kazan Imperial University and the Academic Ladies' Committee to assist affected populations in Kazan Province under the Kazan Spiritual Academy. In addition, women actively participated in the work of the Zemstvo Charity Committee to help the starving population, especially in counties and townships.
Women's social composition included representatives of various estates. Leaders, as a rule, were women of noble origin or intellectuals. Using their own connections and involving in the field, as a rule, teachers, wives of doctors and priests, women benefactors were able to organize help in Kazan province in a fairly short time. The activities of organizations in which women worked were temporary in nature. Having appeared in the period of acute social problems, they stopped their work due to the improvement of the situation.
The role of the Geological Committee of Russia in the scientific study of the Ukhta oil-bearing area
Authors:   Komi Science Centre of the Ural Branch of the Russian Academy of Sciences, Filippova Tatyana P.
Published: December 2024

The conducted research draws attention to learning the experience of national science in the exploration of the northern and Arctic territories of Russia. One of the organizations that made a significant contribution to the scientific study of the North was the Geological Committee, created in 1882 as part of the Mining Department of the Ministry of State Property. The activity of the Geological Committee marked the beginning of systematic geological surveys of the Russian territory. This research based on a wide range of sources analyzes the role of the Geological Committee in the study of the Ukhta oil-bearing area. To date, this problem has not been the subject of separate studies. The identified documentary sources – archival documents of the fund No. 58 "The Geological Committee under the Mining Department" of the Russian State Historical Archive, as well as the published works of geologists (monographs, reports and articles in periodicals) have made it possible to conduct a detailed analysis of the activities of the Geological Committee in the study of the Ukhta oil-bearing area and determine its historical significance. The chronological framework of the study covers the period of the existence of the Geological Committee from 1882 to 1929. During the designated period, the expedition activity of the employees of the Geological Committee (F.N. Chernyshev, P.I. Polevoy, N.N. Yakovlev, A.N. Zamyatin, K.P. Kalitsky, etc.) was developed in the Ukhta district and resulted in the first comprehensive scientific research of this territory. The scientists conducted a detailed geological study of the area, the search for oil fields, and the assessment of their industrial prospects. As a result of the Committee's research, new information about the features of the geological and orographic structure of the Ukhta oil-bearing area was obtained, stratigraphy and tectonics were established, detailed maps were compiled, and the prospects of oil-bearing capacity were substantiated. Scientists of the Geological Committee published the first major works on the Ukhta oil-bearing area, which are still considered classics in geological science. These works not only contained the results of expedition work but also put forward for discussion important socio-economic problems that could hinder the further prospective development of the European North-East of Russia (lack of roads, sparse population, etc.).

Authors:   Tomsk State University, Rumyantsev Vladimir P.
Published: December 2024

This article is devoted to the role of the British politician Harold Macmillan in the Suez Crisis of 1956. Based on British archival documents and MacMillan’s personal diary, this article recreates a double game played by the head of the Treasury. Harold Macmillan belongs to the number of British politicians whose biographies have many «white spots», carefully hidden by themselves and their surroundings. One of these gaps is the activity of Macmillan as the Chancellor of the Exchequer during the Suez Crisis of 1956. From the very beginning of the aggravation of the situation in the Middle East, caused by the nationalization of the Suez Canal Company by the Egyptian government of Gamal Abdel Nasser, Macmillan advocated for a military operation against Egypt. Moreover, he was the first who proposed to involve Israel in this operation in the summer of 1956. The hesitation of the British Prime Minister Anthony Eden, who was afraid to start military actions in the Middle East without the support of the United States, did not suit the head of the British treasury. In order to convince Eden of the need to start a forceful operation against Egypt as soon as possible, Macmillan distorted the information about the negotiations that he held at the end of September 1956 in Washington with the US President Dwight Eisenhower and the Secretary of State John Foster Dulles.
The American allies of London were not against overthrowing Nasser, but insisted that military actions in Egypt should not start before the presidential elections in the US. Macmillan presented the latter condition as optional, emphasizing the readiness of the United States to support the military operation against Egypt.
The start of the aggression against Egypt in the midst of the election campaign in the US caused irritation in the administration of Eisenhower. According to Macmillan, the United States threatened to stop financial aid to Great Britain, which forced the latter to end the military operation in the Suez Canal zone. However, there is no other data on the American pressure, except for the words of the Chancellor of the Exchequer, repeated later in his memoirs.
All this allows ranking Harold Macmillan among the number of the main architects of the Suez Crisis, skillfully combining the implementation of the imperial line of behavior with his own political calculations.
Archival primary sources about the Jewish ancestors of V. I. Ulyanov (Lenin)

The work is devoted to the problem of documentary reconstruction of the Soviet statesman V I. UlyanovLenin’s (1870 – 1924) genealogy. The object of the study is V.I. Ulyanov’s genealogy; the subject is the reconstruction of the matrilineal part of the genealogy in the line of the Jewish family Blank on the basis of archival documents. The source base of the study was the funds of two Ukrainian archives: the Sovereign Archive of the Kiev Region and the Sovereign Archive of the Zhytomyr Region.
Despite the fact that Lenin's genealogy has been studied by domestic and foreign archivists, historians and local lore specialists (P.I. Usachyov, M.G. Stein, A.S. Markov, V.A. Mogilnikov, G.M. Deitch, V.V. Tsaplin, T.P. ZhakovaBasova, O.A. Abramova, G.A. Borodulina, T.G. Koloskova, T.I. Bondareva, Yu.B. Zhivtsova, et al.), to this day, many archival documents about direct ancestors of the Ulyanovs and the Blanks have not been identified and certainly published. During the Soviet times, Lenin's Jewish roots were ideologically banned, so in scientific and popular-scientific literature there are still gaps and inaccuracies in dates of his relatives’ lives and names. To solve this problem, we organized a search for mass genealogical sources in the archives of Russia and Ukraine.
As a result of these studies, valuable archival documents about the direct ancestors of V.I. Ulyanov were introduced into scientific circulation, namely: the sixth census list of December 22, 1811 (January 03, 1812) of the city of Starokonstantinov, the Volyn Governorate, about merchants, artisans and philistines of the Jewish law (the Sovereign Archive of the Kiev Region. Fund 280. List 201. File 263); the eighth census list of the Jews of Starokonstantinov, the Volyn Governorate, April 29 (May 11), 1834 (the Sovereign Archive of the Zhytomyr Region. Fund 118. List 14. File 268); the ninth census list of the Jews of Starokonstantinov, the Volyn Governorate, October 15 (27), 1850 (the Sovereign Archive of the Zhytomyr Region. Fund 118. List 14. File 276). We also clarified the fate of some documents that were withdrawn from Soviet archives in the 1960s, and now are stored in the Information and Documentation Support Department of the President of the Russian Federation in special folder № 3.
Based on the analysis of the sixth census list about the Jews of the small town of Bazalia, the Starokonstantinov County, the Volyn Governorate, September 09 (21), 1811 (the Sovereign Archive of the Kiev Region. Fund 280. List 201. File 263) we hypothesized that the maiden name of V.I. Ulyanov's great-grandmother was not “Froimovich” at all, but “Krelstein”. The appendix to the article contains scanned copies of the identified archival documents about Lenin's Jewish ancestors.
Civil society in the millstones of the Civil War. Review: Dementiev A.P., Drobchenko V.A. Sessions of local governments, congresses, conferences, meetings of public organizations and social groups of the Yenisei province during the Civil War (May 1918 - February 1920) / Scientific ed. E.I. Chernyak. Krasnoyarsk: Union of Local Historians of Yenisei Siberia, 2023. 400 p.
Authors:   Tomsk State University, Larkov Nikolay S.
Published: December 2024

The review analyzes the book of Doctor of Historical Sciences V. A. Drobchenko and Candidate of Historical Sciences A. P. Dementiev, which contains systematized information about 255 of the most significant forms of manifestation (events) of social activity of the population of the Yenisei province during the Civil War in Russia. The first of its two sections contains information about sessions of local governments, congresses, conferences, meetings, plenums of public organizations and social groups held from the end of May to the end of November 1918, the second section contains events from December 1918 to March 1920. A harmonious addition to the main content of the collection is a well-executed historical essay "Yenisei province on the eve and during the Civil War" with a volume of 52 pages. The review evaluates the extensive array of historical sources used by the authors, based on archival documents and periodicals. The structure of the event description is characterized, including 12 parameters (date, venue, number of delegates, their composition, the content of the decisions taken, including full-text resolutions and resolutions, etc.). Attention is drawn to the continuity of the reviewed book with a 9-volume edition devoted to similar events in the Siberian provinces in 1917-1918, which was prepared by historians of Tomsk State University in the early 1990s. It is noted that the greatest share in the book is information about forums held during the existence of anti-Soviet regimes of power by such public structures and social groups as zemstvo bodies, cooperatives, teachers, entrepreneurs, Cossacks, etc. The authors devoted a lot of attention to the forms of manifestation of social activity by participants in the mass anti-Kolchak insurgent-partisan movement. The documents published in the collection show that along with the civil war escalation, the dialogue of society with the authorities in the territory of the Yenisei province was rapidly decreasing, and in the Kolchak region it actually stopped. Under the conditions of the military dictatorship, there was no place for an autonomous social life. As a result, the process of forming civil society in Russia, which had not been completed by that time, led to its grinding in the millstones of the Civil War. Despite the inaccuracies and omissions found in the book, in general, the documented information presented in it on the nature and forms of public activity of the population of the Yenisei province significantly replenishes the array of published sources on the history of the Civil War in eastern Russia, thereby contributing to their wider use by historians, local historians and all those interested in Siberian history.
The Crimea of the XIV–XV centuries in the dialogue of the cultures of Moscow Rus and Byzantium
Authors:   Sevastopol State University, Zhirtueva Natalia S.
Published: December 2024

The aim of this article gives a detailed analysis of the role of medieval Crimea in the cultures dialogue of Moscow Rus and Byzantium of the XIV-XV centuries. This problem has not been touched upon the issue in the research literature yet. The author addresses to the works of researchers such as A. Gertsen, O. Dombrovsky, M. Kolesov, T. Fadeeva, A. Yakobson, and others.
The source base is monuments of literature, art and architecture. The methodology of the study is comparative theological analysis. The main research methods used in the article are comparative-historical, analysis, synthesis, generalization, individualization, historical narrative.
There is every reason to assume that the Crimea of the XIV-XV centuries was in the sphere of influence of the culture of the “Paleologian Renaissance”, which is best seen in the monuments of art of “expressive style”. The influence of Byzantine culture came to the Crimea in two ways - through the Balkan countries to the southwestern Crimea (the Principality of Theodoro), as well as through the Caucasus, to the eastern part of the peninsula. That is why the art of the Crimea of the XIV-XV centuries is distinguished by the features of provincialism.
The culture of southwestern Crimea turned out to be more influenced by the “Paleological Renaissance” than eastern Crimea. Thus, the Crimea, along with the Balkan countries, in the XIV-XV centuries was influenced by the teachings of Gregory of Sinai, which contributed to the spread of the ideas of neohesychasm here. It is also known that in the XIVXV centuries between the Crimea and Moscow Rus there were the closest cultural ties. It can be assumed that from the Crimea the teachings of Gregory of Sinai could penetrate into Rus.
There is practically no information given about the mystical life of the monasteries at this time. It is possible to suppose that at this stage of history the role of the Crimean "cave monasteries" as intermediaries between the mystical centers of Byzantium and Russia was not as significant as in the era of iconoclasm. If in the period of IX-XII centuries the Crimea (Tavrika) played an active role as a translator of orthodox and unorthodox Christianity into the culture of Kievan Rus, then in the XIV-XVcenturies it was no longer the Crimea, but the Balkans that became the main channel for the penetration of ideas of Byzantine neohesychasm into Rus. From the XV centure the cultural life of Crimea is becoming increasingly dependent on Moscow Rus.
