Пароція персидська (Parrotia persica (DC.) C.A.Mey.) – вологолюбний мезотермічний релікт Гірканської флористичної області, що простягнулась вузькою смугою вздовж південного узбережжя Каспійського моря. Біологія та екологія виду відзначаються тими особливостями, які сформувались ще в умовах вологого і теплого клімату третинного періоду, а основна своєрідність ритму розвитку полягає у відсутності чітко вираженого зимового спокою і наявності літнього спокою, який у природному ареалі не пов'язаний з періодом посухи. Першу спробу інтродукції Parrotia persica на півдні материкової частини України здійснив в 30-х роках ХХ ст. директор Одеського ботанічного саду, видатний ботанік і дослідник флори Кавказу, академік Володимир Іполитович Липський.

Мета досліджень полягала в оцінці успішності інтродукції Parrotia persica в умовах «ex situ» об’єктів природно-заповідного фонду двох кліматичних зон України – Приморської посушливої та Північно-західної достатньо зволоженої.

Порівняння фенологічного розвитку середньовікових дерев пароції персидської в Приморській посушливій кліматичній зоні України з умовами природного ареалу показало, насамперед, суттєві відмінності у розвитку генеративних органів: скорочений період цвітіння і недостатнє визрівання насіння, яке навіть у випадку рясного плодоношення має схожість на рівні 1-2%. Характерні також передчасне завершення приросту пагонів (у липні) і явно скорочений період опадання листків (листопад-грудень). В той же час, в умовах Північно-західної достатньо зволоженої кліматичної зони України, у рослин віргінільного періоду онтогенезу спостерігається другий осінній приріст пагонів, а фенофаза листопаду триває до кінця березня наступного року, що подібно до особливостей розвитку залізного дерева у природному ареалі.

Published: April 2024

The aim of the research was to determine the features of the age structure for natural and artificial elm stands depending on species, origin, and region. The proportion of the stand area of natural and artificial stands of each elm species by 10-year age classes was evaluated for the forest fund of the Donetsk, Kharkiv, and Sumy Regional Forest and Hunting Management Administrations (RFHMA). Four main forest-forming elm species are represented in the forest fund of the Donetsk and Kharkiv RFHMA (U. minor, U. laevis, U. glabra, and U. pumila). In the Sumy RFHMA, there are three forest-forming elm species: U. minor, U. laevis, and U. glabra. The maximum age of U. minor is 120, 117, and 91 years in the Donetsk, Kharkiv, and Sumy RFHMA, respectively. The mean and the maximum age of U. minor and U. glabra tends to decrease in the Donetsk – Kharkiv – Sumy RFHMA row. The proportion of U. laevis is larger in man-made plantations than in natural stands, however, in natural stands, it also increases in the Donetsk – Kharkiv – Sumy RFHMA row. U. glabra prevails in natural stands. U. pumila in the Donetsk RFHMA grows mainly in man-made plantations. A decrease in the area of newly formed U. minor stands in the Donetsk RFHMA occurred after the 1950s, and in the Kharkiv RFHMA after the 1960s in both artificial and natural stands. In the Sumy RFHMA, this also happened in the 1960s in man-made plantations. A decrease in the area of U. glabra natural and artificial stands occurred also after the 1960s. We suppose that an epiphytoty of the Dutch elm disease, well-known in Europe in the 1960s, could also be the cause of elm decline in the eastern part of Ukraine. The proportion of the stands’ area preserved up to a certain age, depends on particular elm species, region, and stand origin. However, in order to clarify the survival rate, it is necessary to consider the type of forest site conditions, the proportion of elms in the stand composition, and some other features that are to be analyzed in future research.

Загальна площа лісових земель у Львівському регіоні (області), на яких поширена Pinus sylvestris L., становить 151246,5 га, з яких 94648,8 га (62,5%) зайняті деревостанами штучного походження, а 48898,3 га (32,3%) – природного походження. При цьому соснові лісостани поширені у всіх чотирьох трофотопах – A, B, C і D та у сухих, свіжих, вологих, сирих і мокрих гігротопах. В основному сосна звичайна. в регіоні росте у відповідних для неї клімато-едафічних та фітоценотичних умовах, в яких займає площу 137467,6 га або 90,9% від загальної площі соснових лісостанів. Водночас на площі 13778,9 га (9,1%) вона поширена у не властивих для неї лісорослинних умовах, зокрема в грудах.

Найбільшу площу у всіх типах лісорослинних умов займають чисті соснові деревостани (10 од. – 71592,6 га (47,3%). Поширеними є також деревостани з часткою сосни в складі 6, 7, 8 і 9 од. – 64032,6 га (42,4%). За віком переважають середньовікові соснові деревостани (69723 га або 46,1%). Понад 64% деревостанів за участю Pinus sylvestris характеризуються середньою відносною повнотою (0,51-0,80) та 25,7% є високоповнотними (0,81 і більше).

Соснові деревостани в регіоні відзначаються високою продуктивністю і сягають І, Іа та вищих класів бонітету. Їхня площа складає 12548,1 га (82,3%). Запаси соснових деревостанів уже в пристиглому віці досягають понад 300 м³/га. Найбільший щорічний приріст у всіх типах лісорослинних умов спостережено у середньовіковому періоді – 4,5-5,8 м³/га.

Для забезпечення високої життєвості Pinus sylvestris та збереження соснових деревостанів необхідне регулярне здійснення низки лісогосподарських заходів, серед яких: проведення патологічних обстежень та оздоровчих заходів; своєчасне проведення рубок догляду, рубок головного користування та санітарних рубок; збільшення біорізноманіття лісостанів; створення лісових культур відповідно до едафо-кліматичних умов території регіону та лісонасінного районування; відбір біологічно стійких генотипів сосни звичайної; запровадження вибіркового, наближеного до природи лісівництва.
Pесурсний потенціал та структура клейковільхових деревостанів Українського Полісся
Authors: Lakyda Petro , Smolin Vitaly
Published: April 2024

Стале та раціональне використання лісових ресурсів в умовах переходу лісової галузі України на європейські стандарти і ринкові засади управління потребує системного опрацювання відповідного нормативно-інформаційного забезпечення для оцінювання деревних ресурсів основних лісотвірних видів країни. При цьому інформація про розмірно-якісну структуру запасу насаджень, які відводяться в рубку, має чи не найвагоміше значення у плануванні діяльності лісогосподарського виробництва.

Реалізація цього завдання потребує актуального оцінювання запасів деревостанів за основними таксаційними ознаками. З цією метою проаналізовано структуру основних таксаційних показників деревостанів вільхи клейкої Українського Полісся за даними повидільної бази даних ВО «Укрдержліспроект» станом на 01.01.2011 року. Оцінено ресурсний потенціал деревостанів, придатних до експлуатації, проаналізовано його складові у межах лісового фонду адміністративних областей досліджуваної зони. Встановлено, що вікова структура деревостанів знаходиться в діапазоні 43–50 років, що свідчить про достатній потенціал товарної деревини вільхи клейкої із середнім запасом деревини від 152 м3·га-1 на Рівненщині до 189 м3·га-1 на Київщині. Для досліджуваної категорії деревостанів характерні середні відносні повноти (0,70) та доволі високі класи бонітету (І,8). Понад 80,0% деревостанів мають паросткове походження. Вікова структура лісів регіону нерівномірна з істотним переважанням середньовікових деревостанів. Деревостани вільхи клейкої ростуть практично в усіх типах лісорослинних умов Українського Полісся домінуючи, однак, у сугрудових умовах (87,6%), з них 77,6% – у сирому гігротопі.

Досліджувана категорія насаджень становить вагому частку у лісоресурсному потенціалі лісового фонду України і потребує опрацювання сучасного нормативно-інформаційного забезпечення для оцінювання кількісних і якісних параметрів дерев і деревостанів.

DIARIO DE PERNAMBUCO: DE UMA FOLHA DE ANÚNCIOS AO JORNAL MAIS ANTIGO EM CIRCULAÇÃO NA AMÉRICA LATINA
Authors: de Lima Amaral Tércio
Published: April 2024

Desde o ano de 1908, o Diario de Pernambuco, no Recife, ostenta em seu cabeçalho o seguinte slogan: “o jornal mais antigo em circulação na América Latina” (Nascimento, 1968: 121). Convertido até meados dos anos 2010 em uma potência regional, sendo considerado um dos principais jornais impressos da região Nordeste e do Brasil, o DP, como também é conhecido nos dias atuais, sobretudo pelos jornalistas que atuam ou atuaram na empresa, iniciou seus passos em uma edição histórica em 7 de novembro de 1825. Na época da primeira edição do jornal, Olinda ainda era a capital de Pernambuco – Recife só conquistou o posto em 1827 e permanece assim até hoje –, d. Pedro I era o imperador do Brasil e o Recife ainda era um pequeno burgo, com em torno de 25 mil habitantes, do qual com 69% de pessoas livres, envolta do comércio e da atividade portuária (Martins, 2017: 9). O primeiro gazeteiro do jornal deve ter sido um escravo, que acumulava outra função: ser ajudante da oficina tipográfica (Jambo, 1975: 76).
O TYPHIS PERNAMBUCANO E A CONFEDERAÇÃO DO EQUADOR
Authors: Maria Grego Lins Aline
Published: April 2024

independência do Brasil, proclamada pelo imperador d. Pedro I, em 7 de setembro de 1822, como se sabe, não resolveu os problemas nem os conflitos que vivia a nação ainda em construção, nem na corte no Rio de Janeiro, muito menos nas províncias, a exemplo de Pernambuco, que desde o início do século XIX e, de forma categórica em 1817, já havia experimentado sua revolução republicana, cujos ideais permaneciam vivos em suas vilas e na então capital Olinda. A representação de uma independência tranquila e pacífica, sem contestações ou divisões políticas, criada a partir da perspectiva romântica do Instituto Histórico e Geográfico Brasileiro (IHGB), na segunda metade do século XIX, já com a figura de d. Pedro II e cristalizada no senso comum (Schwarcz, 1998: 126), pode ser descortinada por meio da análise de jornais panfletários e políticos, como é o caso do Typhis Pernambucano, cuja circulação ocorreu entre os anos de 1823 e 1824. Ele teve importante papel na defesa da Confederação do Equador, quando a província de Pernambuco empreendeu, mais uma vez, esforços para implantar um governo federativo republicano, em reação às decisões do imperador calcadas no absolutismo. Sete anos antes, em 1817, na insurreição pernambucana, a província já havia ensaiado esses passos, não só instalando um governo republicano, como também declarando a ruptura com o Reino Unido português. São as ideias federalistas da Revolução de 1817 que voltam à tona em 1824.
Are firewood preference behaviors influenced by restrictions in access to vegetation, and can they vary over time?
Authors: Tavares Mendes Carlos Henrique , Alves Ramos Marcelo , Silva Taline Cristina
Published: April 2024

Studies aim to understand the behavior of human populations when selecting certain groups of plants over others. Some plants are chosen for favorable characteristics that justify specific uses. Thus, individuals may exhibit specialized behavior patterns, selecting plants for fuel based on specific biological traits like ignition potential and durability, or generalized behavior patterns, depending on species availability or utilitarian redundancy. However, little is known about how the preference for these resources may be shaped by contexts that prohibit resource use. Prohibiting resource use can compel human groups to devise new selection strategies, leading to significant changes in socioecological system dynamics. Hence, this study aims to investigate how preference for plants used as firewood varies in areas with restricted and unrestricted resource use. We conducted semi-structured interviews in two communities. Participants with restricted natural resource access in the past showed a tendency towards specialized behavior (p<0.000849). However, due to imposed restrictions, the community had to develop new usage strategies, resulting in a tendency towards generalized behavior (p>0.6489). Preference in unrestricted use areas varied over years, with generalists in the past (p>0.4675) and specialists presently (p<0.2074). Based on these behaviors, we infer that these human groups possess adaptive plasticity to mitigate the drastic effects of long-term wood resource extraction.
Application of the Fourier Modulation Analysis Method to the Problem of Derivatives Recovery
Authors: Kuzmichev Nikolay D.
Published: April 2024

Abstract. In this work, formulas are obtained for finding higher derivatives of a function (dependence), expressed through its Fourier coefficients (harmonic amplitudes). These formulas were found by differentiating both a function with a harmonically modulated argument and its Fourier series. The expressions given make it possible to find higher derivatives of functions numerically with any accuracy by means of different methods. For example, numerical integration of the Euler-Fourier formulas may be used for harmonic amplitudes. Derivatives also can be found experimentally when studying a nonlinear physical process by digitally recording the harmonic amplitudes of the dependence under study under simultaneous static and harmonic influences. The problem of reconstructing derivatives from Fourier coefficients is posed and an analysis of its correctness is performed. Formulas for estimating recovery errors are defined and recommendations are given to reduce these errors. Examples are given with different smoothness of analytical functions and of functions used to explain experiments: 1) an analytical function used to explain the magnetic properties of superconductors, whose Fourier coefficients are determined numerically with the error of the computational algorithm in the Mathcad software environment; 2) current-voltage characteristic (CVC) of 2 back-to-back semiconductor diodes, whose harmonic amplitudes were determined experimentally with a given measurement error of the device. The resulting derivative of the current-voltage characteristic is compared with the derivative obtained using numerical differentiation formulas; 3) an analytical function whose derivative has a discontinuity of the first kind. Errors in measuring Fourier coefficients were added artificially using a random number generator.

Various factors influence marginal bone loss after implant placement. This study explored the association between marginal bone loss and posterior implants positioned at different bone levels. Computer records and radiographs of patients with at least 2 adjacent implants were retrieved. Cases were categorized into nonsplinted prosthesis and splinted prosthesis groups. Radiographic measurements were conducted at the time of abutment placement (T0), 1–3 years follow-up (T1), and the last visit (T2), measuring the vertical distance between adjacent implants. Multilevel linear regression models using generalized estimating equations were employed, with a significance level set at 5% (α = 0.05). Fifty-six patient records were included, comprising 120 implants: 84 nonsplinted (70%) and 36 splinted (30%). In the nonsplinted group, marginal bone loss progression significantly depended on crestal height differences. For the mesial sides of posterior implants, marginal bone loss measured 1.0 ± 0.6 mm from T0 to T1, 2.4 ± 1.1 mm from T1 to T2, and 3.4 ± 1.2 mm from T0 to T2. Similarly, the distal sides of the most anteriorly placed implant exhibited marginal bone loss of 1.0 ± 0.7 mm from T0 to T1, 2.4 ± 1.0 mm from T1 to T2, and 3.5 ± 1.2 mm from T0 to T2. Nonsplinted implants demonstrated a higher progression of marginal bone loss. This study suggests that nonsplinted implants may lead to a more pronounced progression of marginal bone loss, particularly concerning crestal height differences, underscoring the need for further research.

Published: April 2024

One of the mechanisms for the development of small business is the organization of state inter-district business incubators. At the same time, a correct assessment of the effectiveness of their activities is necessary, reflecting the economic positive changes in the economy of the municipalities to which the graduates of the business incubator are sent. The authors propose a methodology for evaluating the effectiveness of a business incubator, taking into account both the overall economic effect of a newly created business and the contribution of the incubator's employees to the results of its activities based on determining a private indicator of business performance and the employee's KTV. Domestic and foreign practice shows that business incubators are one of the tools to accelerate the social and economic development of any municipal area and the country as a whole. Business incubators can play a significant role in organizing their own business in the development of small businesses. The proposed methodology will allow evaluating the results of the business incubator, taking into account the available resources and the existing needs of the market of municipalities and the region. The authors focus on the fact that for the development of small business, the effective use of the available resources of the municipality, it is necessary to create state business incubators that orient the population of municipalities to promising activities when creating their own business. The main objective of these incubators should be the creation of successful entrepreneurs in municipalities. Based on this, the assessment of the activities of the proposed business incubators should be considered from the standpoint of the effectiveness of both personnel and business results of graduates («grown» entrepreneurs). The article presents calculations of the efficiency of a newly opened business in a business incubator. In addition, the assessment of business projects of graduates was carried out. In the final part of the article, the authors formulate conclusions regarding the role of business incubators in ensuring economic development, supporting small businesses and the population as a whole.
The feasibility of using biogas generated from livestock manure as an alternative energy source: A South African perspective
Authors: Moreroa M. , Motshekga S.C.
Published: April 2024

Electricity usage has risen tremendously over the years, as has its price. This resulted in an increase in the quest for less expensive, viable, and ecologically acceptable means of producing energy for electricity. Currently, the primary source of power in South Africa is sourced from fossil fuels, which have negative environmental consequences. The use of biogas as an alternative can mitigate the impacts of using fossil fuels to generate power. This study has examined the availability and accessibility of waste that may be utilized to generate biogas using common South African livestock excrement. A typical South African home uses 31 kWh of power daily, which equates to 111.6 MJ of energy. According to calculations, about 30 m3 of biogas is needed to produce enough energy to power a household. For the generation of mono-digestion biogas, 12 beef cows, 8 dairy cows, 3898 chickens, 156 pigs, 281 sheep and 300 goats would be needed to meet this need. Moreover, the livestock dung required to meet the daily requirement of 31 kWh is 713 kg for beef and dairy cows, 390 kg for chickens, 468 kg for pigs, 506 kg for sheep and 466 kg for goats. Co-digestion of various wastes is nonetheless a viable and advised method for enhancing the amount and quality of biogas.
DECOLONISING LABOUR LAWS AND REPOSSESSING SUBALTERN EPISTEMOLOGIES: A REVIEW OF SOUTH AFRICAN AND NAMIBIAN MINEWORKERS’ FIGHT FOR LABOUR RIGHTS
Authors: Warikandwa Tapiwa
Published: April 2024

In the historical and current transformation discourses in South Africa and Namibia, the concept of decolonisation is no longer a mere abstract concept. Decolonisation is now a fundamental policy and regulatory imperative that is heavily centred on, among other things, the land question and debates around the historical as well as present-day use of indigenous cheap and unskilled labour in underpaid sectors of industry –particularly the mining sector. During the colonial era, as the mining industries in South Africa and Namibia expanded, a substantial number of migrant labourers and local workers entered the mines. To safeguard these mineworkers’ legal rights, labour laws were passed. Despite the implementation of such labour laws, regular strikes were a feature of the mining industries in South Africa and Namibia at the time. In the post-colonial dispensation, the South African mining industry has been characterised by numerous strike actions, while in Namibia, widespread dissatisfaction with working conditions has been noted. This raises the question of whether or not South Africa and Namibia have made progress in defending mineworkers’ labour rights. This question is critical when viewed through the lens of a post-colonial society governed by a constitutionalised labour law framework. While there has arguably been a noticeable improvement in mineworkers’ employment conditions, labour-related inequities continue to characterise the mining industries in South Africa and Namibia in the post-colonial era. Profiteering, capitalism, safeguarding the security of tenure of foreign mining corporations, and the persistent need to ensure the ease of doing business in the mining sector appear to take precedence over defending mineworkers’ rights. Thus, this article explores the labour rights discourse developed by South African and Namibian mineworkers, as well as the applicable labour legislation. A strong case is made for reconsidering the extent to which South African and Namibian labour laws have been decolonised. This is done in a manner that is attentive to investment security and sustainable growth of the mining sector in the two countries as well as the realisation of African mineworkers’ fundamental labour rights.
ASSESSING THE INVESTIGATIVE POWERS OF THE COMPETITION COMMISSION IN MERGER REGULATION AND CHALLENGES POSED BY THE DIGITAL ERA S.O.S Support Public Broadcasting Coalition v South African Broadcasting Corporation (SOC) Limited [2018] ZACC 37
Authors: Mpofu Kudzai , Tavuyanago Simbarashe
Published: April 2024

The South African Competition Commission (the Commission) is celebrated as the most efficient and effective body in implementing competition law. The Commission is an independent and impartial body whose primary function includes investigating and prosecuting complaints raised against firms for failing to report notifiable mergers. Over the past decade, it has reviewed several mergers and successfully prevented many anti-competitive market structures.While the Competition Act (89 of 1998) (CA) empowers the Commission to conduct investigations, the scope and extent of these investigative powers has been unclear. This question was the subject of protracted litigation between the parties in S.O.S Support Public Broadcasting Coalition v South African Broadcasting Corporation (SOC) Limited ([2018] ZACC 37). In that case, the Constitutional Court was called upon to decide whether the Commission’s investigative powers included the authority to subpoena witnesses to appear before it. The decision of the court is a welcome addition to competition law jurisprudence insofar as it creates legal certainty concerning the powers of the Commission, especially in light of recent amendments to the Competition Amendment Act (18 of 2018) (CAA), which now broadens the scope of the Commission’s authority and powers. However, in light of some of the arguments that were brought up regarding missing documents, the case also serves as a warning of the challenges that the authorities may face in a more digital economy, especially relating to their exercise of investigative powers in the context of digital security, encryption and offsite storage of information. This note provides a chronological discussion of the facts, evaluates the court’s decision, highlights possible challenges to future investigations and provides concluding remarks.

Authors: Mubangizi John Cantius
Published: April 2024

The worst global disaster of the twenty-first century so far, COVID-19, has caused major disruption to people’s lives and livelihoods and exposed inequalities within and among countries. Developing countries, particularly in Africa, have been hardest hit as they have had to face unprecedented challenges, with potentially extreme economic, social and sustainable development consequences. Existing challenges were worsened by COVID-19 with significant implications not only for sustainable development, but also for human rights. This article first discusses the relationship between human rights and sustainable development. The discussion then turns to the impact of COVID-19 on sustainable development with a focus on specific and relevant Sustainable Development Goals (SDGs), and on the protection and enjoyment of human rights in Africa. The article concludes by recommending a human rights-based approach as a clear and compelling direction to sustainable development in Africa in the aftermath of the devastating and unprecedented COVID-19 pandemic.
Serum copeptin in women with gestational diabetes mellitus: A meta-analysis
Authors: He Yuanqi , Li Xue , Li Xiaoxiao , Cui Weiwei , Zhang Shihong
Published: April 2024

Previous studies have reported mixed results regarding the relationship between serum copeptin levels and gestational diabetes mellitus (GDM) risk. To address inconsistencies in prior research, this meta-analysis examines the potential link between serum copeptin levels and the risk of developing GDM. Our objective was to comprehensively evaluate this association. We systematically reviewed observational studies from Medline, Web of Science, Embase, Wanfang, and China National Knowledge Infrastructure (CNKI) databases up to October 15, 2023, employing a random-effects model to integrate the data while considering heterogeneity. This analysis incorporated 10 studies comprising 625 women with GDM and 1212 healthy pregnant controls. Our findings showed no significant difference in serum copeptin levels between women with GDM and those without (standardized mean difference [SMD] 0.01, 95% confidence interval [CI] −0.22 to 0.24, P = 0.92, I2 = 75%). Univariate meta-analysis indicated a positive correlation between the body mass index (BMI) of the participants and the outcomes (coefficient = 0.11, P = 0.002). Further subgroup analysis demonstrated that women with a mean BMI ≥ 26 kg/m2 and GDM had significantly higher serum copeptin levels compared to their non-GDM counterparts (SMD 0.31, 95% CI 0.05 to 0.57, P = 0.02, I2 = 46%). Conversely, no difference was observed in women with a BMI < 26 kg/m2 (SMD −0.23, 95% CI −0.37 to−0.09, P = 0.002, I2 = 0%, P for subgroup difference = 0.003). Variables, such as the country of study, maternal age, the timing of blood sampling, copeptin measurement methods, or GDM diagnostic criteria did not significantly affect the results. In summary, the association between serum copeptin levels and GDM risk is influenced by the BMI of pregnant women, indicating that elevated serum copeptin might be linked to GDM in individuals with a BMI ≥ 26 kg/m2.

Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Seliverstova Anastasiia
Published: April 2024

The systematic and continuous study of new lexical units is intrinsically linked to the dynamic evolution and constant changes in the lexical structure of the language, as well as the integration and adaptation of neologisms into the language. The article examines and gives examples of neologisms of modern social networks, analyzes the peculiarities of their formation, focusing on the tendency of using new words and expressions in online communication, especially among young people. The profound impact of social networking on life of modern generations is described, the vocabulary disparities across different age groups is juxtaposed. The distribution and significance of Italian neologisms are analyzed, and their impact on language and culture is determined. The results of the study underscore not only the evolutionary trajectory of the Italian language but also its pivotal role in articulating sociocultural trends within modern society through the pervasive adoption of neologisms.
GENDER PROVOCATIONS IN SOCIOLINGUISTIC AND PSYCHOLINGUISTIC APPROACH
Authors: Tkachenko Nataliya
Published: April 2024

The article deals with the manipulating tactics of the verbal and nonverbal gender provocations. The article novelty may be attributed to the first attempt to describe and classify the varieties and forms of the men’s and women’s provocations, their social, pragmatic and psychological factors. The object of the article is the men’s and women’s provocation communicative tactics. The concrete task is set to investigate the communicative verbal and nonverbal men’s and women’s provocation communicative tactics. Methods of gender provocations research cover sociolinguistic, psycholinguistic, cultural linguistic interpretation analysis of men’s and women’s communicative interaction in vivo. Power is believed the principal social factor of gender difference that can be explained by the men’s physical force. Women are marked with the highest intra-gender and inter-gender competition in the struggle for their living and social needs. Women’s communicative provocations to men include ambitious, soothing, encouraging sayings, and critical, insulting, depreciating, dishonoring sayings about women and with women aimed at competition and power. Men’s provocations are mostly nonverbal – with eyes, actions, objects. Competition in both interpersonal and demographic women’s policy influences the social and ethnic structure of the countries. In recent times the ideological attitude to gender language was increased. Gender provocations reveal men’s and women’s communication distinctions in understanding genders relations, evaluations, expressiveness, topics choice, nonverbal means, etc. The historical tendency of women’s copying men’s speech style, considerably worsened lately. The communicative intra- and inter-genders difference is observed mostly in socio-psychological communication aspect due to the social and national interpersonal relations.

Authors: Budiyono Fathur , Firman Achmad , Setiati Ray , Rah Erika
Published: April 2024

Acute lymphoblastic leukemia (ALL) is most common in children, especially those aged 1–4 years old, and the second most common acute leukemia in adults. The updated International Consensus Classification (ICC) of B-acute lymphoblastic leukemia (B-ALL) and T-acute lymphoblastic leukemia (T-ALL) includes recent clinical, cytogenetic, and molecular data. Transcriptome sequencing (RNA-seq) was performed on 200 bone marrow specimens using TruSeq library preparation and HiSeq 2000/2500 or NovaSeq 6000 sequencers (Illumina). The purpose of this study was to define the frequency of chromosomal abnormalities of ALL patients in adults and children in Indonesian patients after full remission for international collaboration has improved and advanced the diagnosis and treatment of ALL in Indonesia. Our resulting data showed that the most common structural abnormality was t(9;22) in 15% of the patients. The frequency of genetic abnormalities was 69 % and 60% for numerical and/or structural in the B-ALL and T-ALL patients, respectively. The adults had a higher incidence of t(9;22) and a lower incidence of hyperdiploid than children. In conclusion: The results of this study molecular subtypes differ strikingly in their responses to treatment that needs more assessment.
Comparison of the effectiveness of stabilizing quasi-resonant and inertial influences on the parameters of a controlled Lorentz system with dynamic chaos
Authors: Afanasyev V.V. , Loginov S.S.
Published: April 2024

Problem statement. The article is devoted to determining the comparative energy efficiency of stabilizing quasi-resonant and inertial effects on the parameters of a controlled discrete-nonlinear Lorentz system with dynamic chaos. Currently, information transmission systems based on the use of chaotic dynamics effects are developing extremely intensively. The need to ensure reproducibility of parameters and statistical characteristics of pseudorandom signals generated on the basis of nonlinear systems with dynamic chaos makes the task of stabilizing chaotic modes of nonlinear devices and systems urgent. Goal. Determination of the comparative energy efficiency of stabilizing quasi-resonant and inertial effects on the parameters of a controlled discrete-nonlinear Lorentz system with dynamic chaos. Results. It is shown that fluctuations causing deviations of the discrete-nonlinear Lorentz system from equilibrium states lead to changes in the quasi-resonant frequency and the effectiveness of inertial stabilizing effects. It is established that the effectiveness of stabilizing inertial effects on parameter b of a controlled discrete-nonlinear Lorentz system increases with an increase in the fluctuation deviation of the system from equilibrium states. The conditions under which stabilizing inertial effects become energetically more advantageous than quasi-stationary effects on the parameters of a discrete-nonlinear system are determined. Practical significance. Ensuring the required regular behavior with the transfer of nonlinear electronic and quantum devices and systems from stochastic to regular mode.
On the issue of capacitively coupled circuits using to explain the mutual influence of wires
Authors: Dmitrikov V.F. , Shushpanov D.V.
Published: April 2024

The wire, as a separate element, is practically never sanctified in the literature. There is no radio-electronic device without a wire. It is the frequency characteristics of the wire impedance that limit the frequency characteristics of the inductor impedance, i.e. limit the frequency range of the radio interference filter. Therefore, it is important to understand the physics of the processes occurring in the wire. In addition, it is important to understand how the wire “parasitic” parameters affect the other elements “parasitic” parameters. An explanation for the presence of capacitance in a wire equivalent circuit through the skin effect phenomenon is proposed in this article. The using of the concept of capacitively coupled circuits as a dual analogue of inductively coupled circuits is proposed. It is shown that the duality of inductively coupled circuits and capacitively coupled circuits is possible only due to the duality of the alternating vortex magnetic field and the alternating vortex electric field. The viability of using the concept of capacitively coupled circuits is shown using the example of the measured impedance of two wires in various variants of parallel connection.

Authors: Khairullin A.N. , Lerner I.M. , Ayupov T.A.
Published: April 2024

Problem statement. At that moment, it is relevant to create algorithms for communication channels capacity estimation within the framework of the Theory of Resolution Time for broadband wired telecommunication systems, which use bipolar PAM-n-signal whose execution time complexity is linear. The creation of such algorithms is of high importance both for wired network technologies (Ethernet, InfiniBand etc), and in the field of creating high-speed interchip connections, high-speed memory controllers and peripheral computer buses, since it will allow to improve channel capacity at low computational costs in real-time regime due to the transition to the “above Nyquist speed” regime. Target. Develop an algorithm which has linear computational complexity in the framework of The Resolution Time Theory for frequency-selective communication channels capacity estimation with a linear receiver and PAM-n-signal. Results. An algorithm for estimating specific channel capacity and resolution time is presented, which has linear computational complexity, depending only on the value of the effective memory, for continuous frequency-selective communication channels with a discrete source, in which information is transmitted utilizing bipolar PAM-n-signal. This algorithm has no restrictions on the pulse shape, and the computational complexity linearly depends on the channel memory. The key features of the algorithm are considered, allowing its application in real time. The developed algorithm allows to user fully estimate all the effects caused by data depended jitter. Practical significance. The proposed algorithm makes it possible in real time to select the shape of a partial pulse and the configuration of the signal constellation that increase the specific capacity of a communication system with serial data transmission, including under conditions of transmission in the “Faster than Nyquist” regime.

Published: April 2024

The performance of modern heterogeneous Radio Access Networks (RANs) can be improved by introducing new methods and algorithms for network resource management. In particular, user mobility information can be used to control RAN resources. To determine user mobility, information about the variation of the Signal to Interference + Noise Ratio (SINR) between base stations and users can be collected and analyzed. These data are multi-linear and can be represented as tensors to extract information from them. However, for the tensors decomposition, it is necessary to know the order of the multi-linear model or the rank of the tensors. Inspired by the LaRGE (LineAr Regression of Global Eigenvalues) method, we propose a novel method for the model order estimation of the multi-linear data based on the analysis of the Complimented Global Eigenvalues (CGE) profile. We have denoted our method as Enhanced LaRGE (EnLaRGE). We have compared the EnLaRGE method with the classical methods AIC, MDL and their multi-linear versions, as well as with the M-EFT and N-D EFT methods. EnLaRGE shows good performance for the tensors with small one of the tensors dimensions. EnLaRGE method is implemented for the automatic model order estimation of multi-linear data received from the Network Simulator 3 with RAN Intelligent Controller (RIC). The results show the high precision of the multi-linear model order estimation in comparison with state-of-the-art methods. The estimated model order can be used for user mobility classification and improving heterogeneous RANs performance.

Published: April 2024

Problem statement. Currently, many leading companies in the field of electronics, radio engineering, and aerotechnics are concerned about the depletion of non-renewable resources such as platinum, gold, silver, indium and even the more common lithium, nickel and copper, which they actively use in their products. The design and synthesis of nanostructures with controlled morphology has attracted the attention of many researchers and engineers, since it is much more efficient to deposit a small amount of metal on the surface being used than to create a part entirely from this metal. There are several main methods for producing nanostructures on a surface: chemical deposition, electron beam lithography, pulsed laser deposition, electrochemical deposition and other methods. Electrochemical deposition is worth highlighting among all methods, because it makes it possible to obtain such surfaces relatively cheaply and on a large scale and control their morphology by changing deposition conditions, such as time, potential, solution pH, etc. Purpose of the study. Obtain nickel-containing nanoparticles on glassy carbon by electrodeposition from an aqueous solution of biopolymer complexes of sodium pectate with divalent nickel; to determine the influence of electrodeposition conditions, namely, the duration of deposition and the content of Ni(II) ions in sodium petectate complexes, on the morphology of the resulting surface. Results. Studies have been carried out of the influence of electrodeposition conditions on the morphology of the resulting glassy carbon electrode surface. It was found that biopolymer ligands act as a stabilizing agent for the formation of nickel-containing nanoparticles instead of a nickel-containing layer. The standard sizes of the resulting nanoparticles are in the range of 20 – 90 nm. The nickel content in the complexes, as well as the deposition time, proportionally affects the amount of deposited nanoparticles, but has little effect on their sizes. Practical significance. The results obtained make it possible to use them for controlled electrodeposition of nickel-containing nanoparticles on conducting surfaces in the development of nonlinear optical devices, LEDs, diodes, transistors, logic gates, sensors and other electronic devices.

Published: April 2024

Now days, due to the trend towards reducing energy costs, non-destructive input monitoring of various characteristics of LEDs is becoming one of the promising areas for research. From the technical side, the optimal option can be considered 100% control of all products according to all characteristics. However, at the same time, economic costs increase, leading to an increase in the price of LED technology products. An additional obstacle to testing modern LEDs is the lack of markings on the component, which makes it impossible to visually separate high-quality LEDs from well-known brands from counterfeit components. The aim is the selection of the optimal set of parameters according to their technological spread for monitoring the quality and reliability of LEDs based on an analysis of their electrical, light and thermal characteristics. Based on the experimental results, a limited set of parameters of LEDs was determined based on the analysis of their electrical, light and thermal characteristics, the use of which can be used in their express diagnostics, which allows reducing economic costs during production and control, and time costs during the rejection procedure by ourselves developer. It is shown that the most informative for predicting quality and reliability are light and thermal characteristics.
Regularization of the RLS algorithm for adaptive digital predistortion
Authors: Kashchenko I.E. , Pavlov A.P.
Published: April 2024

Problem statement. Modern digital pre-image input systems, as a rule, involve the use of adaptation algorithms to correct their parameters. Adaptation algorithms are solutions based on LMS and RLS methods. At the same time, the efficiency, in terms of the convergence rate and the accuracy of the solution, of RLS methods is significantly higher. This is due to the presence of a covariance matrix as part of the solution based on the RLS method. However, when using RLS algorithms (an adaptation algorithm using the RLS method), problems may arise related to poor conditionality of the covariance matrix resulting from signal noise, high inertia of the nonlinear properties of the power amplifier, limited accuracy of parameter calculation, etc. To solve this problem, it is advisable to use the regularization procedure of the RLS algorithm, taking into account the specifics of the digital predistortion systems. Objective. Creation and analysis of the regularization procedure of the RLS algorithm for adaptive input systems of digital presets. Results. The paper presents the implementation of the regularization procedure of the RLS algorithm for adaptive input systems of digital presets. Using the regularization procedure of the RLS algorithm avoids the state of poor conditionality of the covariance matrix, thereby ensuring stable operation of the digital pre-order input system. The state of the covariance matrix is monitored at each iteration of the RLS algorithm by evaluating the trace of the matrix. Practical importance. The proposed solution can be used to stabilize the parameters of adaptive systems for entering pre-orders based on RLS algorithms.
