Published: March 2022

The aim of this study was to determine the influences of different feeding materials on the physico-chemical parameters of vermicompost using Eisenia fetida. In this study, four treatments, with the same conditions in terms of organic wastes type were prepared to produce vermicompost from hazelnut husk (% 100), tea plant waste (%100), hazelnut husk (A) (% 50) + tea plant waste (B) (50%), hazelnut husk (A) (30%) + tea plant waste (30%) + cow dung (20%) + sawdust (15%) + waste newspaper (%5) using earthworms. The standard laboratory analysis methods were used to determine the physical and chemical parameters in the different produced vermicomposts. The mean N content in the growing medium A, B, C, and D was 1,41%, 2,5%, 1,96%, and 1,47% respectively. The mean phosphorus content in the growing medium A, B, C, and D was 807,69 mg/kg, 1748,25 mg/kg, 1491,25 mg/kg, and 1410,75 mg/kg respectively. The mean potassium in the growing medium A, B, C, and D was 11244,69 mg/kg, 7790 mg/kg, 6884,25 mg/kg, and 8006,25 mg/kg respectively. Compared to the initial vermibed mixture, the N, P, and K content was higher in all the growing mediums. The Pb, Cd and As content was lower in all the growing mediums in the final compost than the initial vermibed mixture. Eisenia fetida is very effective in converting some waste materials into high-quality compost and decreasing the heavy metal content in the final vermicompost more than in the initial vermibed mixture.

Aim to evaluate the severity of tinnitus before and after medical treatment in military personnel exposed to high-intensity noise.
Material and methods. The study involved 14 soldiers with complaints of tinnitus who suffered hearing damage caused by gunshot noise (AK74 gun) during military training without hearing protectors. The tinnitus severity and its dynamics during the treatment by glucocorticosteroids was assessed using the Tinnitus Functional Index (TFI). The Tinnitus Handicap Inventory (THI) was used before the treatment, on the 3rd and 7th days after the treatment.
Results. It was found that the greatest discomfort was caused by the intrusiveness of noise and inability to control it during the day, and the least discomfort was associated with sleep. The changes in the severity of noise on the THI and TFI scales on the third and seventh days after treatment were significantly different, if compared with the pre-treatment results, and had a positive trend. The therapy provided the significant decrease of noise intrusiveness and established the sense of noise control during the day, as well as minimized its effect on relaxation, hearing and quality of life, if compared to the data before treatment.
Conclusion. The TFI and THI scales are recommended for assessing the severity of tinnitus and monitoring the treatment of patients exposed to high-intensity noise. Particular attention should be paid to the use of personal hearing protection equipment when working in conditions of increased level of noise.

Published: March 2022

Aim determination of the most informative combination of biomarker tests and modern methods of radiological diagnosis of kidney tumors in clinical practice.
Material and methods. The study included clinical and morphological data of 133 patients with kidney tumors. In order to identify the informative markers of kidney tumors, such indicators as gender, age; CT and ultrasound imaging results; vascularization, density, tumor contrast, histological examination, levels of tumor pyruvate kinase and vascular endothelial growth factor were analyzed. The results were statistically processed using Statistica 10 and SAS JMP 11 software.
Results. Determination of biomarkers showed a significant increase in the level of tumor pyruvate kinase and vascular endothelial growth factor in the group of patients with kidney cancer. The TuPKM2 level in these patients reached 46.3 27.2 u/l, and in the group with benign tumors 27.8 16.4 u/l, the VEGF indices were 330.0 42.91 pg/ml and 266.3 26.39 pg/ml, respectively (p 0.05). The analysis of CT results showed that in the group of patients with kidney cancer, hypervascular mass was diagnosed much more often than in the group with benign tumors (69.5% and 26.7%, respectively) (p 0.05). Vascularization is associated with the histology of neoplasms. The nature of contrast and density, determined using CT, are interrelated. The ROC analysis revealed that the most important variables for the diagnosis of kidney cancer are vascularization (relative risk = 1.24) and an increase in TuPKM2 levels above 15 u/l (relative risk = 1.24).
Conclusion. The study results revealed TuPKM2 and the nature of tumor vascularization to be the key markers for the diagnosis of kidney cancer. The groups of patients with different neoplasms had statistically significant difference in terms of TuPKM2 and VEGF. In clinical practice, a comprehensive study for kidney tumor diagnosis is rational, including the determination of tumor pyruvate kinase in combination with ultrasound examination of the kidneys and computed tomography.

Authors: Torba Aleksandr V.
Published: March 2022

Aim to investigate changes in phase contents of bone mineral of the hipbone in pre-senile streptozotocin-induced diabetic rats after surgical perforation of the tibia.
Material and methods. Diabetes was induced in 35 animals with an initial weight of 290-310 g at the age of 17-18 months by a single intraperitoneal injection of streptozotocin in dosage of 55 mg per kg of body weight. Surgical perforation of the tibia was modeled as 2.0 mm opening in the proximal metadiaphysis (35 animals). Another group comprised 35 animals with both perforation and diabetes. 35 intact animals comprised the control group. The content of whitlockite, calcite and hydroxylapatite in bone mineral of the hipbone was determined.
Results. Surgical perforation of the tibia resulted in instability of phase contents of bone mineral of the hipbone by the 15th day of observation; peak of deviations was registered on the 90th day of observation, when the proportions of whitlockite and calcite increased by 7.20% and 8.91%, while the proportions of hydroxyapatite decreased by 3.53% in comparison with the controls. In diabetic animals, the destabilization of the phase composition of bone mineral was observed by the 7th day of the experiment. By the 90th day, the proportion of whitlockite and calcite exceeded those of the controls by 9.00% and 9.01% while the proportion of hydroxylapatite decreased by 4.00%. Surgical perforation of the tibia in diabetic pre-senile animals resulted in more marked increase of hipbone mineral amorphousness from the 7th day of observation; by the 90th day the proportion of whitlockite exceeded this in rats with perforation by 7.95%, while the proportion of hydroxylapatite decreased by 2.35%.
Conclusion. Surgical perforation of the tibia in diabetic pre-senile rats results in increasing of the amorphousness of bone mineral of the hipbone, which grows starting from the 7th day after operation.

Published: March 2022

Introduction. Trust in the financial sector of the economy affects the coherence of the financial system and macroeconomic stability. In this regard, it is essential to provide a thorough methodological basis that will be the basis for studying this concept. The multifaceted nature of the researched concept presupposes multilevel bibliometric analysis based on analytical tools ScopusTools, Google Trends, and VOSviewer.Prupose. The study aims to conduct a multilevel bibliometric analysis of research on trust in the financial sector.Methods. The methodological basis of the study is a set of scientific publications indexed in the scientometric database Scopus for 1863-2021. To achieve this goal, the following general scientific research methods were used: analysis of scientific literature, theoretical synthesis, grouping, sampling method, contextual content analysis, evolutionary-temporal and spatio-temporal analysis, comparative and cluster analysis.Results. The obtained results testify to the growing tendency of scientific research on trust in the financial sector. Six stages of scientific interest have been identified, so the stage of active development of research falls on 2008-2012. and 2015-2018. The geographical centers of research are the United Kingdom, the United States, and Canada; these countries began to explore the concept of trust in the financial sector earlier than other countries. Analysis of the sectoral structure of research on trust in the financial sector demonstrates the interdisciplinary nature of the phenomenon under the study. A comparative analysis of Google’s search queries shows that one of the key conditions for overcoming macroeconomic imbalances can be considered trust in the financial sector. Cluster analysis identified five main research clusters.Discussion. The prospect of further research is to apply the results of the bibliometric analysis to form a clear structure of factors of trust in the economy’s financial sector and develop a scenario of action due to its violation.

The historical method provides an opportunity to study the main stages of occurrence of foreign economic activity in chronological order.Results. The level of development of any power in the modern world directly depends on its foreign economic activity. It is shown that for the entire period of formation of the Ukrainian state (from the times of Kievan Rus to the present), the foreign economic activity has passed a difficult way of development. The evolution from the trade relations form to international activity took place during this way with the distinct list of object and business entities. It is improved and supplemented the historical stages of the emergence of foreign economic activity in Ukraine. The concept of «foreign economic activity» is described and justified.Prospects. The study results made it possible to gradually reproduce the development of foreign economic activity in a historical sequence. However, the concept of «foreign economic activity» needs further research and clarification, as there are significant differences in its definition by the scientific community and existing Ukrainian legislation.
Demography in the function of resolving geopolitical crises
Authors: KUKA Ljubica
Published: March 2022

Migration expansion is especially pronounced in the dynamic processes that take place within contemporary societies. The reasons for large migrations of the population are primarily found in the imposed conflicts by the world's leading countries. The latest largest conflict started at the end of 2010 with the „Arab Spring“, that is a wave of demonstrations against the dictatorial regimes in the Arab countries: Tunisia, Egypt, Libya, Algeria, Iraq, Morocco, etc. The crisis continues with the war that started in Afghanistan (2001 - 2021), which is considered the longest war in the history of the United States, and then the civil war in Syria, which began in 2011. The consequences of these war conflicts manifested in a large number of refugees coming from the Middle East, North and Central Africa, and Central and South Asia, who have moved to Europe. An important strategic direction in the migration route to Europe went through the Balkans. The assumption is well-founded on demographic indicators, that just the underdeveloped and the developing countries of the so-called „Western Balkans“ in the incoming period, will accept the largest number of emigrants, in order to resolve the long-standing migration crisis.

Tractable Maximum Likelihood Estimation for Latent Structure Influence Models with Applications to EEG & ECoG processing
Authors: Karimi Sajjad , Shamsollahi Mohammad Bagher
Published: March 2022

Brain signals are nonlinear and nonstationary time series, which provide information about spatiotemporal patterns of electrical activity in the brain. CHMMs are suitable tools for modeling multi-channel time-series dependent on both time and space, but state-space parameters grow exponentially with the number of channels. To cope with this limitation, we consider the influence model as the interaction of hidden Markov chains called Latent Structure Influence Models (LSIMs). LSIMs are capable of detecting nonlinearity and nonstationarity, making them well suited for multi-channel brain signals.
Design and modelling of a continuum robot with soft stiffness-adjustable elements for confined environments
Authors: MA NAN
Published: March 2022

Abstract—Continuum robots are increasingly used in a
wide range of industrial applications due to their slender body and high
redundancy, making them ideal for intervention in confined environments.
However, most of the existing continuum robots operate with their backbone in a
cantilever configuration, resulting in a limited accuracy at the tip because of
their low stiffness. This paper proposes a new method to improve the stiffness
of continuum robots, characterized by: (1) a modular section with adjustable
stiffness (MSAS), able to inflate its diameter by ten times to provide physical
support for a 6-DoF operating section; (2) a novel stiffness model developed to
study the behaviour of the hybrid stiffening continuum arm; (3) a manual insertion
method for an easy delivery with a limited number of actuators. The proposed stiffness
model, which combines the stiffness characteristics of the MSAS and a 6-DoF
continuum arm, predicts the performance of the novel hybrid continuum robot
with an average deviation of 9.2% under external loads. A prototype has been
demonstrated on a case study in a Trent 900 aeroengine, where the MSAS, with a natural
diameter of 12.6 mm, is delivered through an inspection hole of 13 mm and then
inflated (120 mm) to successfully
lock the robot within the combustor (width: 200 mm; height: 110 mm). The physical
support enables accurate operation with the 6-DoF continuum arm at the tip, indicating
that the proposed design can improve the performance of conventional continuum robots.

Introduction. This article presents the results of isolation of camel smallpox virus (Poxviridae: Orthopoxvirus: Camelpox virus, CMLPV) and study of its reproductive properties on sensitive biological systems.Material and methods. The epizootic strain M-96 of the virus as well as its attenuated variants KM-40 and KM-70 obtained by sequential passivation were used in the study. Isolation of the pathogen from suspension of biopsy specimens was performed on cell culture and in embryonated chicken eggs (ECEs). All experiments were performed with the number of replications ensuring obtaining reliable results.Results. The CMLPV was isolated from the crusts and pox papules of the skin taken from sick camels (Camelus bactrianus) during an outbreak in various districts of the Mangistau region at the end of 2019. The signs of pathogen reproduction on chorio-allantoic membrane (CAM) were observed from 3 passages. The obtained virus caused formation of pathological changes on the CAM in the form of elevated dot or solid white formations separated from the surrounding tissue, with hemorrhagic foci in the center. The reproductive properties of the isolate on sensitive biological systems were determined in comparison with the epizootic CMLPV strain M-96, isolated earlier in the territory of Kazakhstan during the outbreak 23–24 years ago, as well as its attenuated variants. The isolated virus was given the conventional name M-2020.Discussion. When studied in two sensitive cultivation systems (cell culture and ECEs), strain M-96 and its attenuated variants KM-40, KM-70, which were used in the experiments as a control, demonstrated high infectious activity with titer 4.75-6.75 lg TCID50/cm3, while for the examined isolate M-2020 of CMLPV had the significantly lower values (3.00-4.75 lg TCID50/cm3, p 0,05).

Introduction. The study of the intensity of humoral immunity to the measles virus (Paramyxoviridae: Morbillivirus) (MV) remains relevant due to the ongoing registration of the cluster cases of measles (including nosocomial cases).The aim of the study was to analyze correlation between the intensity of the humoral immunity to measles virus and the measles incidence in different age groups of the Moscow residents.Material and methods. A simple analytic study was carried out under the framework of measles prevention improvement program conducted in the subjects of the Russian Federation. The study included the analysis of the reasons for the increase in the proportion of seronegative individuals and the comparison of the results of seromonitoring with the data of age-related measles incidence. Throughout 2018, total 1,855 blood serum samples obtained from employees of a large hospital center in Moscow who were previously vaccinated against measles were tested for IgG antibodies (ABs) to MV. The subjects were divided into 11 groups according to their age. Statistical analysis of the obtained data was performed using nonparametric criteria.Results and discussion. The proportion of seronegative individuals among the staff of the medical facility decreased with age, from 38.5% in persons aged 19–23 to 0% among employees aged 64 and over. Persons aged 19–43 years were the most susceptible to measles infection, which was confirmed also by the highest incidence rate at these age groups (from 6.93 to 14.03 per 100,000 population). The age group most protected against measles was those over 64 years of age, who were all seropositive and had the lowest rates of incidence. This is probably due to the fact that by this age most of them have had a measles infection and have formed a sufficient immune response. At the same time, younger individuals living in the post-elimination era have only vaccine-induced ABs to MV, the level of which declines rapidly to non-protective values in the absence of boosterization due to the exposure to the wild-type strain of the pathogen.Conclusion. The monitoring of the MV-specific IgG- AB levels is required for employees in the medical institutions under the age of 35. Administration of the single dose of the appropriate vaccine is recommended for seronegative individuals.

Authors: Glotov A. G. , Glotova T. I. , Nefedchenko A. V. , Koteneva S. V.
Published: March 2022

The genus Pestivirus of the family Flaviviridae includes 11 species. Bovine pestiviruses are the causative agents of viral diarrhea/mucosal disease and include three genetically distinct species: pestivirus A (BVDV-1), B (BVDV-2), and H (BVDV-3). The number of BVDV-1 subtypes is 21, BVDV-2 – 4, and BVDV-3 – 4, which complicates the diagnosis of associated diseases, reduces the effectiveness of vaccination and control programs.We performed the search in the PubMed, Web of Science, Scopus, eLIBRARY.RU databases for articles published in 2000–2021.Pestivirus A is distributed everywhere, although the largest number of subtypes was found in cattle in Italy and China. The virus is widespread in the Central region of the Russia (subtypes 1a and 1m). In Siberia, eleven subtypes circulate among native and imported animals: 1a (5%), 1b (35%), 1c (5%), 1d (10%), 1f (20%), 1g, 1i (both 2.5%), 1j, 1k, 1p, and 1r (all for 5%). Pestivirus B subtype is more virulent, found less frequently and mainly in the North and South America, in some European countries, and in Asia. Three subtypes have been identified in Siberia: 2a (25%), 2b (10%), and 2c (5%). Pestivirus H circulates in Europe, Asia and South America. The main route of entry is contaminated biological products. In Russia, BVDV-3 of the Italian-Brazilian group (3a) was detected in 7 lots of fetal bovine serum.The role of the virus in the occurrence of respiratory diseases in calves, abortion, systemic infection and enteritis in calves and adult animals has been established. The source of the virus in such cases was a contaminated modified live vaccine.

Authors: Bromo Francesco
Published: March 2022

Scholars frequently give attention to the case of Italy for the purposes of comparative research. Whether they are concerned with assemblies, cabinets, leaders, or most aspects of governance, Italy often features in studies involving parliamentary systems. To aid students interested in examining the Italian case, I introduce a comprehensive dataset that tracks elections, governments, heads, and legislatures in Italy from 1720 to 2021. The dataset covers the Kingdom of Sardinia (1720-1861), the Kingdom of Italy (1861-1946), and the Italian Republic (1946-2021). Primarily, the dataset fills the lacuna vis-à-vis the availability of pre-WWII data. In this research note, I display the features of the dataset as well as presenting one example related to premature dissolutions of the Italian Parliament.

АНАЛІЗ І СТРАТЕГІЯ ПОКРАЩЕННЯ ХАРЧОВОГО СТАТУСУ НАСЕЛЕННЯ УКРАЇНИ
Authors: Ощипок І. М.
Published: March 2022

В статті розглянута важлива проблема збереження й зміцнення здоров’я населення. Проведено аналіз законодавства з регулювання продовольчої захищеності, який підтверджує, що концептуально не конкретизовані результати продовольчого забезпечення як об’єкта регулювання, не забезпечуються на достатньому рівні методичними підходами для ефективного його поновлення. Визначено фактори продовольчої безпеки та якісного харчування. Розглянуто площини забезпечення ефективних ліній постачання харчових продуктів і зменшення їх втрат під час зберігання та утворення харчових відходів. Опрацьовано напрями забезпечення практичних шляхів збереження здоров’я для виявлення суті “здоров’я”. Відмічено шість основних типів сутнісних елементів визначення здоров’я. Показана вимога парадигми сталого розвитку агропродовольчого виробництва за системою пріоритетів, які відповідають економічним інтересам господарюючих суб’єктів в поєднанні з їх екологічною та соціальною відповідальністю. Досліджено роль ФАО і ВООЗ з розробки та впровадження міжнародних програм, спрямованих на стабілізацію системи харчування населення і забезпечення харчового статусу населення України. Відзначено рівні споживання окремих харчових продуктів щодо раціональних норм, % цілого ряду продуктів, у т.ч. молочних (52,7 %), м’яса та м’ясних продуктів, включаючи субпродукти і жир-сирець (66,7 %), хлібні продукти (у перерахунку на борошно; крупи, рис, бобові) (96,8 %), яйця, шт. (97,1 %). Населення України споживає більше норми овочів та баштанних продовольчих культур (у т.ч. картоплі) (187 %), недостатню кількість свіжих плодів, ягід та винограду (без переробки на вино) – (65,2 %) відповідно щодо рекомендованих МОЗ України норм здорового харчування. Відзначені негативні тенденції забезпечення продовольчої безпеки останніх років через: незбалансованість харчування; скорочення розмірів власного виробництва окремих продуктів, споживання значної кількості продуктів нижче оптимальних норм, погіршення якості харчування, економічної недоступності продовольства внаслідок загального невисокого ступеня доходів населення. Показано найвищу диференціацію рівня життя населення за суспільними групами, збільшення імпорту практично за всіма продовольчими групами, що приводить до стримування становлення вітчизняного виробника. При цьому передбачається погіршення загальної позитивної перспективи у сфері продовольчої безпеки і харчування через присутність пандемії COVID-19.
ЦИФРОВИЙ РОБОЧИЙ ПРОСТІР ЯК СКЛАДОВА СУЧАСНОГО РИНКУ ПРАЦІ
Authors: Чернятевич Я. В.
Published: March 2022

У статті розглянуто сутність цифрового робочого простору як складової частини сучасного ринку праці. Встановлено, що внаслідок глобалізаційних процесів в економічних системах на передній план виходять цифрові технології, автоматизовані системи управління, віддалена (дистанційна) праця, розвиток економіки знань та інформаційного суспільства. Виявлено, що 2020 рік приніс значні зміни у сфері організації праці, в системі реалізації професійної діяльності людини, в підходах до розуміння особистісного розвитку, наслідком чого став пошук шляхів адаптації людей до так званої нової реальності. З’ясовано, що поняття цифрового робочого простору є досить новим у науковому обігу і водночас досить уживаним. Не існує єдиного визначення цього терміна, однак це не заважає компаніям та організаціям використовувати його для побудови стратегій розвитку та функціонування. Встановлено, що під цифровим робочим простором можна розуміти певне інтегральне утворення, що охоплює цифрові процеси, засоби цифрової взаємодії, інформаційні ресурси, цифрову інфраструктуру та інші поняття, що є характерними для цифровізації загалом. З’ясовано, що в Концепції розвитку цифрової економіки та суспільства України цифрове робоче місце визначається як віртуальний еквівалент фізичного робочого місця, котрий вимагає належної організації, користування та управління, оскільки воно має стати запорукою підвищеної ефективності працівників та створення для них більш сприятливих умов праці. Зроблено висновок про те, що у нинішніх умовах змінюється роль людини у виробничих процесах, зростає потреба у творчих кадрах, важливими ознаками робочої сили стають креативність, комунікабельність, нестандартне мислення, адаптивність тощо. Саме інтенсивний розвиток цифровізації, загальносвітові тенденції (в тому числі, пандемія коронавірусу COVID-19), прискорений розвиток цифрового простору та перехід на цифрові робочі місця є і причинами, і наслідками реалізації нових якісних ознак сучасної людини на ринку праці.
