Precision and Accuracy Limits of Wastewater-Based Epidemiology—Lessons Learned from SARS-CoV-2: A Scoping Review
Authors: Laicans Juris , Dejus Brigita , Dejus Sandis , Juhna Talis
Published: April 2024

Background: Wastewater-based epidemiology (WBE) has become crucial for early microbial outbreak detection and public health surveillance globally, underscored by the COVID-19 pandemic. However, despite advancements in sampling and analyses, interpreting results and estimating infection rates pose challenges. Enhancements in sewer system engineering, understanding the wastewater environment, and addressing the impact of the environment on the accuracy of results are needed. Objective: This scoping review aims to identify engineering knowledge gaps in WBE to guide future study designs. Design: Research on “wastewater-based epidemiology” involving “engineering”, published between 2015 and 2023, was extracted from the Scopus database. Results: This scoping review examines elements influencing WBE’s precision and reliability, especially in identifying and measuring SARS-CoV-2 RNA. It identifies significant effects of engineering, analytical practices, and the wastewater’s composition on WBE performance. Conclusions: This review calls for further investigation into economical evaluation methods of these factors to enhance WBE data normalization and interpretation, utilizing existing wastewater treatment plant data used for treatment control, which could be a cost-effective approach over more expensive population biomarkers. This approach, aside from SARS-CoV-2, holds potential for application to a broader number and types of diseases, as well as population consumption habits.
Fractal Characteristics of Water Outflows on the Soil Surface after a Pipe Failure
Authors: Iwanek Małgorzata , Suchorab Paweł
Published: April 2024

Water pipe failures result in real water losses in the form of water outflowing into the porous medium, such as the surrounding soil. Such an outflow may result in the creation of suffosion holes. The appropriate management of the water supply network may contribute to reducing the number of failures, but due to their random nature, it is not possible to completely eliminate them. Therefore, alternative solutions are being sought to reduce the effects of the failures. This article presents a fragment of the results from a broader scope of the research, which attempted to determine the outflow zone in relation to the fractal characteristics of water outflows. The research included the analysis of the actual geometric structures created by the water outflows, which were simplified into linear structures using isometric transformations. The structures were analyzed in terms of the parameters characterizing them, including their fractal dimensions. As a result, it was found that there was no relationship between the analyzed fractal parameters and the leakage area or hydraulic pressure in the water pipe. However, the influence of the number of points forming each linear structure on the analyzed parameters was shown. This allowed for the determination of further research aimed at estimating the size of the water outflow zone after the unsealing of an underground water supply pipe.

Authors: Adetokunbo Peter , Ismail Ahmed , Mewafy Farag , Sanuade Oluseun
Published: April 2024

The operator of Chimney Rock Dam observed the emergence of increasing seepage at the toe of the dam when the water level in the reservoir exceeded a particular elevation. However, the source and the pathways of the seepage were not identified. To address this issue, integrated geophysical methods were employed to delineate the different units of the dam embankment and identify potential seepage zones and pathways. The methods utilized in this study included electrical resistivity tomography (ERT), self-potential (SP), and multichannel analysis of surface waves (MASW). The ERT profiles revealed variations in the dam’s fill properties, including areas with anomalously low resistivity, interpreted as zones of relatively high moisture content. The two long SP profiles conducted along the dam embankment displayed similar spatial correlations with these low-resistivity zones, suggesting potential preferential seepage pathways. The SP map generated from a suite of parallel SP profiles conducted over the abutment depicts a pattern of positive background and negative potential anomalies, which may suggest fluid movement or seepage potential. The MASW profile along the top of the dam characterized an upper low shear-wave velocity layer corresponding to the top dry section of the embankment underlain by a higher shear-wave velocity layer, interpreted as saturated zone. The utilized geophysical methods successfully characterized the different materials of the embankment and identified zones of potential seepage.

Published: April 2024

Disposal of biosolids, the solid fraction of sewage treatment, is a global environmental issue. Biosolids contain valuable organic matter and plant nutrients; however, they also contain contaminants including trace elements, xenobiotics, and pathogens. The quality of the biosolids greatly depends on the source of wastewater (i.e., industrial vs. domestic) and the treatment processes. We aimed to determine the potential of three distinct biosolids and one pond sludge to grow indigenous plants for ecosystem restoration. For each amendment, we tested six indigenous species, Veronica salicifolia, Corokia cheesemanii, Griselinia littoralis, Phormium tenax, Poa cita, and Cordyline australis in bark mixed with biosolids and/or pond sludge at rates of 0–50%. There was a significant positive correlation between plant growth and biosolid addition up to a species-dependent plateau. Growth decreased at the highest rates. At a rate of 10% for fresh biosolids and 30% for aged biosolids provided consistent optimal growth across all species. The pond sludge was unsuitable for the establishment of indigenous seedlings. At the optimal rates, there were significant increases in foliar N, P, K, S, and Zn. None of the trace elements accumulated in the plants at phytotoxic concentrations or levels that presented a risk to ecosystems. Future work should determine how plants raised with biosolids perform once planted out in the field.

Authors: Colmenarejo Calero Elvira , Kovač Viršek Manca , Mali Nina
Published: April 2024

Microplastics (MPs), defined as plastic particles measuring less than 5 mm, are considered an emerging pollutant. Their presence in the water cycle and their interaction with ecological processes pose a significant environmental threat. As groundwater (GW) represents the primary source of drinking water, monitoring MPs in GW and investigating their potential sources and pathways is of urgent importance. This article offers a comprehensive overview of the primary contamination pathways of MPs from surface water, seawater, and soil into the GW. Moreover, it presents an examination of the occurrence of MPs in GW and identifies the challenges associated with their monitoring in GW. This study also discusses the difficulties associated with comparing research results related to MPs in GW, as well as indicating the need for implementing standardised techniques for their sampling and detection. On the basis of our experience and the literature review, we highlight the importance of understanding the specific hydrogeological and hydrogeographic conditions, collecting representative samples, using sampling devices with comparable specifications and comparable laboratory techniques for MP identification, and preventing contamination at all stages of the monitoring process. This review offers valuable insights and practical guidelines on how to improve the reliability and comparability of results between studies monitoring MPs in GW.
Effects of Bio-Organic Fertilizers Substitution on Gaseous Nitrogen Losses in Rice Fields
Authors: Han Zhengdi , Hou Huijing , Yao Xianzi , Qian Xiang , Tao Qin , Zhou Mingyao
Published: April 2024

Traditional practices for managing irrigation and fertilizer in Chinese rice fields have historically consumed large amounts of water resources and caused serious gaseous nitrogen losses (ammonia volatilization and N2O), resulting in low water and fertilizer use efficiency. While both water-saving irrigation and substituting organic fertilizer for chemical fertilizer can impact ammonia volatilization and N2O emissions, the impact of their combined application on gaseous nitrogen loss in rice fields remains unclear. To achieve this goal, we conducted a two-year experiment using two irrigation methods and three bio-organic fertilizer substitution modes. The experiment investigated the effect of different irrigation and fertilizer management techniques on gaseous nitrogen losses in rice fields. The result indicated that controlled irrigation could reduce the peak value of ammonia volatilization by 36.8~75.9% and ammonia volatilization accumulation by 45.8%. However, it also leads to a 71.4% increase in N2O accumulation emissions, resulting in a 43.0% reduction in gaseous nitrogen losses. Compared to full chemical fertilizers, bio-organic fertilizer substitution could effectively reduce the peak of N2O and ammonia volatilization. Cumulative ammonia volatilization and N2O emissions went down by 22.7~60.0% and 38.6~42.6%, respectively. This then led to a 23.4~52.9% drop in total gaseous nitrogen losses. In contrast, the utilization of controlled irrigation and bio-organic fertilizer substitution did not have a significant impact on rice yield. However, it did reduce the intensity of gaseous nitrogen loss from rice fields by 42.7% and 22.5% to 56.5%, respectively. When taken together, the substitution of bio-organic fertilizer in controlled irrigation can effectively reduce gaseous nitrogen losses while maintaining rice yields. This study has significant practical implications for reducing nitrogen loss from paddy fields, improving water and fertilizer utilization, and achieving sustainable agricultural development.
Using the Heavy Metal and Biotic Indices to Assess Ecological Quality in the Central Area of the East Sea, South Korea
Authors: Liang Jian , Ma Chae-Woo , Son Dae-Sun
Published: April 2024

With the rapid development of the South Korean economy, human activities have extensively affected Korea’s coastal environment. A precise ecological quality assessment remains paramount despite the relatively lower impact of human activities on the East Sea compared to the West and South Seas of South Korea. Accurate ecological quality assessments can provide valuable marine environmental protection and management references. In our study, we employed seven indices based on heavy metals and macrobenthos to comprehensively assess ecological quality. Our results indicated the final ecological quality in the central East Sea of South Korea was acceptable at most stations; however, the ecological quality in winter marginally falls short compared to that in spring. The concentration of heavy metals emerges as a significant determinant of the final ecological quality, underscoring the need for subsequent studies to investigate the origins of heavy metals in the central East Sea of South Korea and the influence of anthropogenic activities on heavy metal concentrations. Furthermore, employing a single biotic index proves challenging for accurately assessing ecological quality in the East Sea of South Korea.

Authors: Strizhkova L. A.
Published: April 2024

The article presents the results of the author's research devoted to the improvements in domestic developments of Input-Output Tables (IO Tables), significantly increasing their analytical potential. According to the author, the level of development of Russian statistics in the field of Input-Output Tables is quite high – the basic accounts contain not only the symmetrical IO Tables, but also symmetrical tables of domestic products and imports that they are derived from. This is the main condition for implementing the methodology and methodological solutions described and elaborated in the article for compiling the tables with the coefficients of total costs of domestic products and the total need for import of intermediate imports estimates.In the first part of the article, the author characterizes conceptually different versions of the intersectoral model with the features of the technological matrix corresponding to these versions – the basis for estimating the values of total costs coefficients in the national economy. Three «extreme» variants of the economy model representation of indicative country are studied. They define the economy as a part of a global economy within the framework of an inter-country model; in the form of a national model without the allocation of the import matrix in a symmetrical IO Tables (traditional method) and in the form of a national model with the possibility of such allocation (alternative method). The substantial differences in the values of total costs coefficients for the options are described and their preference for study of the country's economy is emphasizedThe second part of the article presents the results of a quantitative analysis based on the basic IO Tables for 2016 data. It contains the estimates of the measure of discrepancy in total costs coefficients values according to traditional and alternative methods; the differences in the associated indicators of intermediate products total costs distribution by specific dimensions of final demand. The analytical possibilities of the alternative method are described, the estimates for the decomposition of final products cost into domestic and imported value added are provided.The author explains the analytical relevance of total costs coefficients using an alternative method in forecasting practice and in the macroeconomic effects of management decisions assessment and proposes to supply the basic IO Tables for 2021 with tables with these coefficients and with the necessary methodological explanations
The Use of Multipliers in Assessing the Economic Effects of Digital Transformation of Territories (Case Study: Novosibirsk Region)
Authors: Glinskiy V. V. , Serga L. K. , Yushina K. S.
Published: April 2024

Development of the digital transformation of the state, the economy in general, business and society creates the need to quantify its results and assess the level of impact on the economy. The paper explains a methodological approach to calculating digital economy multipliers for territories based on the calculation of total income (direct and indirect) from digital activity. The multiplier measures the impact of the digital economy on macroeconomic and regional indicators, helps assess the extent of this impact and study its dynamics. The authors calculated digital economy multipliers for the Russian Federation and at the regional level (using the example of the Novosibirsk region) and estimated total digital sector income with a multiplier effect. The paper concludes with the contribution of digital transformation to the economic growth of the Russian Federation and the development of the Novosibirsk region about the multiplier dynamics and the ratio of direct and indirect effects in the total income of the digital sector. Rosstat data for 2017–2021 served as the information base for empirical calculations.
Statistical Scientists in the Academy of Sciences: To Mark the 300th Anniversary of the Russian Academy of Sciences (RAS)
Authors: Dmitriev A. L. , Eliseeva I. I.
Published: April 2024

The paper covers the 300 years of the history of the Russian Academy of Sciences, which embodies the intellectual potential of Russia. The authors focus on the figures of academic scientists who have left their mark on the history of Russian statistics. It is stressed that the choice of personalities – members and corresponding members of the Academy of Sciences – was relative due to the complex structure of the Academy itself when а branch or a department of the Academy nominates a scientist to the rank of an academician or a corresponding member, as well as an ambiguity of a scientist’s contribution if the area of subsequent activity of the elected member of the RAS strained from the profile of the nominating division of the Academy. When discussing personal achievements, the authors adhered only to chronology, consistently moving from one historical phase to another, from one system of government to another. It is difficult to review the three centuries of the Academy of Sciences in any detail; this explains the lapidary style and the lack of description of the features of Russian history in each period and their impact on scientific research priorities. The article may be of interest to researchers, teachers and post-graduate students of economic universities, as well as employees of state statistics institutions in Russia.

Il est raconté, ici, comment, depuis près de cinquante années d’écriture poétique et romanesque, un écrivain a trouvé dans diverses archives le point de départ, et souvent une bonne partie de la matière d’un certain nombre de ses romans ou de ses poèmes. Comment le document agit-il ? Où est-il consulté ? Dans quel état d’esprit, dans quel état de corps se trouve le chercheur (qui en l’occurrence n’est pas un professionnel de l’Histoire) devant les archives ? Un dialogue est engagé entre le document brut et l’oeuvre littéraire.
Métamorphoses de bâtiments en centres d’archives
Authors: Saïe-Belaïsch France
Published: April 2024

La transformation d’un bâtiment à caractère patrimonial fort en bâtiment d’archives s’inscrit dans une politique de reconversion d’édifices qui n’est pas récente. La conservation du patrimoine écrit trouve une résonnance certaine avec la conservation du patrimoine bâti. Des volumes que l’architecture d’aujourd’hui ne produirait plus, trouvent un nouvel usage, tout en respectant les diverses fonctionnalités d’un service d’archives. Témoignage d’une sensibilité patrimoniale, dans un contexte de développement durable, l’éventail des architectures réhabilitées est très large : architecture militaire, religieuse, industrielle, scolaire. Chaque cas de figure est spécifique mais de façon générale, le patrimoine architectural reconverti trouve une nouvelle reconnaissance dans ces réhabilitations nombreuses, le plus souvent pour des services d’archives municipales. Ce qui n’exclut pas cependant les autres options à étudier suivant le contexte : constructions neuves (bâtiment principal ou annexe), ou extension d’un bâtiment existant de qualité.
Les Archives, décor de fictions ?

Published: April 2024

Les Archives départementales du Val-de-Marne, pour l’architecture du bâtiment imposante et reconnaissable, sont utilisées comme décor de fictions depuis trois ans. Un régisseur d’une société de production a jeté son dévolu sur le bâtiment et son intérieur pour représenter, dans une première production, les archives de la Préfecture de police et pour la deuxième, le lieu de travail d’une documentaliste en charge des dossiers de la police permettant de résoudre des délits. La préparation des décors est un travail commun entre les techniciens de l’équipe de production et la personne en charge du bâtiment associée à la bonne volonté des agents. L’équipe de tournage, attentive à ne pas trop déranger les habitudes de chacun, a contribué à faire de ces tournages une réussite. Évidemment, outre une expérience intéressante, les tournages représentent une manne financière non négligeable qu’il faut mettre en rapport avec les journées perdues pour le service et la gêne pour les lecteurs par la fermeture éventuelle de la salle de lecture. De plus, la série policière et les nombreuses images du bâtiment, des abords, de l’intérieur et des rayonnages, ont participé à une couverture médiatique de notre direction auprès des élus, de la direction générale ou de certains services qui découvrent que les archives de leur département existent.
Les lettres 79 et 84 de Sénèque à Lucilius : un art poétique ?
Authors: Pierre Maxime
Published: April 2024

By addressing the question of poetic imitation in Rome, Seneca’s letters 79 and 84 to Lucilius extend in many ways the Poetic Art of Horace : following the Horatian path, the philosopher uses the image of the bee making honey from many flowers as a symbol of the creator who assimilates his predecessors. This leads him to question the way in which the poet, using his ingenium, creates a unique whole from a diversity of sources. Not only this analysis perfectly fits to the Augustan poets, particularly to Horace in his lyric poetry, but it can give us new clues to read Seneca’s tragic corpus. By bringing together the three Greek tragedians in a single work in Latin, Seneca repeats Horace’s strategy consisting in the appropriation of Greek prestigious predecessors. By this refoundation of a Greek genre in Rome, Seneca may be seen as the “ last Augustan poet”.

Paddy Rice Mapping Based on Phenology Matching and Cultivation Pattern Analysis Combining Multi-Source Data in Guangdong, China
Authors: Sun Lingyu , Yang Tianyao , Lou Yuxin , Shi Qian , Zhang Liangpei
Published: April 2024

Paddy rice mapping is crucial for cultivation management, yield estimation, and food security. Guangdong, straddling tropics and subtropics, is a major rice-producing region in China. Mapping paddy rice in Guangdong is essential. However, there are 2 main difficulties in tropical and subtropical paddy rice mapping, including the lack of high-quality optical images and differences in paddy rice planting times. This study proposed a paddy rice mapping framework using phenology matching, integrating Sentinel-1 and Sentinel-2 data to incorporate prior knowledge into the classifiers. The transplanting periods of paddy rice were identified with Sentinel-1 data, and the subsequent 3 months were defined as the growth periods. Features during growth periods obtained by Sentinel-1 and Sentinel-2 were inputted into machine learning classifiers. The classifiers using matched features substantially improved mapping accuracy compared with those using unmatched features, both for early and late rice mapping. The proposed method also improved the accuracy by 6.44% to 16.10% compared with 3 other comparison methods. The model, utilizing matched features, was applied to early and late rice mapping in Guangdong in 2020. Regression results between mapping area and statistical data validate paddy rice mapping credibility. Our analysis revealed that thermal conditions, especially cold severity during growing stages, are the primary determinant of paddy rice phenology. Spatial patterns of paddy rice in Guangdong result from a blend of human and physical factors, with slope and minimum temperature emerging as the most important limitations. These findings enhance our understanding of rice ecosystems’ dynamics, offering insights for formulating relevant agricultural policies.

Wrongful adoption: who is liable?
Authors: Macía Morillo Andrea
Published: April 2024

The article analyzes the possible claim that may arise in the context of an adoption when the adoptive parents are not informed of certain conditions of illness or disruptive behavior present in the adoptee prior to the constitution of the adoption. Based on the US experience in relation to wrongful adoption actions, it is studied whether it would be possible to file a parallel liability claim in the field of Spanish Law or there are significant differences between both systems that justify their rejection in our legal system. Beyond studying whether the alternative of ending the relationship legally created by means of an annulment of the adoption fits in such cases, the analysis focuses on the most problematic issues regarding the possible claim, namely the damage and the subjective imputation parameter, and whether such a remedy is the most appropriate to solve this type of problems.
Episodic knowledge on first and foremost crystalline structural report of ethylenediamineteraacetic acid (EDTA) itself
Authors: Noguchi Daisuke
Published: April 2024

An investigation into the precise crystalline structural report of ethylenediaminetetraacetic acid (EDTA), a representative chelator learned in the education of analytical chemistry, was initiated as there appeared to be apparent ambiguity regarding the accurate notation of EDTA as a neutral molecule or a zwitterion. Consequently, the first and foremost article reporting EDTA as zwitterionic form was determined after a difficult confirmation. Additionally, crystallographic data of the zwitterionic EDTA itself and non-chelated salts thereof registered on the CCDC are also summarized herein. This episodic knowledge will be fundamental for not only chemical education but also related fundamental and applied sciences.

Published: April 2024

Background: We aimed to examine the feasibility of intensive lifestyle habituation with a subsequent home program, including forest-based exercise, as an alternative approach to conventional cardiac rehabilitation for both primary and secondary prevention of coronary artery disease (CAD).Methods: A total of 28 participants were included in a 1-week intensive education program aimed at fostering desirable lifestyle habits in the study: 17 patients who underwent percutaneous coronary intervention and 11 participants at high risk of CAD. Subsequently, they engaged in a self-directed, home-based program that included unstructured exercise in an urban forest. The terrain of the urban forest was analyzed to estimate metabolic equivalent levels and to assess safety and accessibility for patient exercise.Results: Throughout the program, no adverse cardiac events were reported. Additionally, risk factors for CAD—including body composition, blood sugar levels, hemodynamic variables, total cholesterol levels, and cardiorespiratory endurance—showed significant improvement in both groups.Conclusions: Intensive lifestyle habituation and unstructured, self-directed exercise in the forest were as effective and safe as conventional cardiac rehabilitation for patients with CAD. The study demonstrated that an urban forest could serve as a safe exercise environment in both primary and secondary prevention strategies for CAD.

Graves’ disease – management of Graves’ orbitopathy and thyrotoxicosis, including new therapies
Authors: Toboła Agata , Gietka-Czernel Małgorzata
Published: April 2024

Graves' disease (GD) is the most common cause of hyperthyroidism in countries with adequate iodine supply, and its main extrathyroid manifestation is thyroid orbitopathy. For many years, thyrotoxicosis has been treated with antithyroid drugs, radioactive iodine therapy and thyroidectomy, and glucocorticoids have remained the standard treatment of thyroid eye disease (TED). Currently, there is a growing trend of using targeted therapies in the treatment of thyroid orbitopathy (TO). The significant development of immunobiology, a better understanding of the pathophysiology of the disease and a multitude of studies on new therapies give hope for better treatment results and an improvement in the quality of life of patients.
The aim of the paper is to discuss the current principles of management of Graves' disease, including thyroid orbitopathy, with particular emphasis on new therapeutic methods. The potent role of K1-70TM and small molecule thyroid stimulating hormone (TSH) receptor antagonists in the treatment of hyperthyroidism is indicated. Not only do we point out the promising outcomes of combining glucocorticoids with mycophenolates, but also highlight the use of teprotumumab, rituximab, cyclosporin A, azathioprine, methotrexate, tocilizumab and sirolimus in the therapy of active moderate to severe form of orbitopathy. The protective and supportive effect of statins in the treatment of TED is noted. The limitations of the research results mentioned in the paper are remarked and the need for further randomized studies of long-term safety and efficacy in a larger group of patients is underlined.
Subclinical hypercortisolemia – a therapeutic dilemma
Authors: Tuszyńska Agata , Bednarek-Papierska Lucyna
Published: April 2024

Subclinical hypercortisolemia is the most common secretory function disorder of the adrenal glands caused by the presence of adenoma or hyperplasia of the adrenal cortex.  The primary hormonal test performed in the diagnosis of an incidentaloma is a test with 1 mg of dexamethasone. Lack of cortisol suppression after taking 1 mg of dexamethasone is a screening test for hypercortisolemia. Depending on the clinical symptoms, we are able to distinguish between overt and subclinical forms of cortisol excess. Subclinical hypercortisolemia does not cause somatic features of Cushing's syndrome.
However, even a slight excess of cortisol has been found to significantly increases cardiovascular risk, prevalence of osteoporosis with vertebral fractures and impairs glucose tolerance. In patients with subclinical hypercortisolemia, there are no determined criteria to define strict indications for adrenalectomy. There are many studies showing the beneficial effect of resection of the adrenal adenoma producing cortisol, which led to a reduction in blood pressure and an improvement in the metabolic profile in patients. However, these positive changes do not apply to all patients. As a result, the current European recommendations refer to surgical treatment only when pharmacological treatment fails to achieve good control of hypertension, glucose metabolism or weight reduction.
Some authors believe that not only the adrenal gland tumor may be a cause of the metabolic syndrome, but on the other hand, the hyperinsulinism causes adrenal hyperplasia and excessive secretion of cortisol. In every clinical case, the surgery indication should be carefully analyzed. Primary management is the implementation of pharmacological treatment, regular physical activity and an appropriate diet.

It is shown that the process of the formation of the structure and mechanical properties of plates products is determined by the change of the temperature of the roll through the stages of the production process in the line of a reversing plate mill. An analytical temperature model is developed, that allows to estimate the distribution of surface and average mass temperature along the length and width of the roll for various stages of rolling with intermediate cooling, considering the deformation conditions for each pass. The temperature model is tested; as result, the proposed model can be used to calculate the distribution of the average mass temperature along the length and width of the roll at various stages of the production of plates on reversing mills.

Когда вирус присутствует в организме, он вызывает нехватку клеток крови, в том числе белых кровяных клеток, которые являются ключом к борьбе с инфекцией. В данной статье мы рассмотрим способ лечения кошек, больных панлейкопенией и разберемся какими путями передается это заболевание. После выздоровления на 10-й день животного можно вакцинировать. Вакцину лучше выбрать нобивак или фелиген. Для лечения животных применяли цефтриаксон, метрогил, омез, катобевит. Если животное сильно вырывает, серению вводили, температуру сбивали мелоксидином. Дозировку, способ введения и длительность курса описали в статье.

При ректальной пальпации фолликулярные кисты яичников представляли собой тонкостенные полости с флюктуирующей консистенцией и диаметром от 1,5 до 3,0 см. После повторного исследования у 11,11% животных диагноз не подтвердился. У коров с одиночными фолликулярными кистами наблюдались круглая или овальная форма. При ректальном исследовании яичники были небольшого размера, упруго-плотной консистенции, а на их поверхности отсутствовали желтые тела и фолликулы. Сравнительный анализ показал, что у лактирующих бесплодных коров с овариальными дисфункциями вызванной гипофункцией и фолликулярными и лютеиновыми кистами яичников наблюдалось снижение содержания альбуминовой фракции в крови.

В статье представлены материалы исследований по размножению в культуре in vitro подвоев яблони. Выявлены наиболее оптимальные условия стерилизации и введение в культуру in vitro подвоев яблони ПБ (Парадизка Будавского), М9, М26, М4. Наибольший процент стерильных и жизнеспособных эксплантов отмечен у подвоя М9 (90 %). Применение регуляторов роста (6-БАП и ИМК) способствует увеличению роста побегов подвоев. Наибольший приростом побегом подвоев, при применении 6-БАП отмечаем у ПБ (3,2 см при концентрации 1,0 мг/л, и 3,4 см при концентрации 2,0 мг/л) и на подвое яблони М9 (3,6 см-1,0 мг/л и 3,8 см - 2,0 мг/л), а на подвое М4 (3,5 см-1,0 мг/л и 3,6 см - 2,0 мг/л). Положительно влияет регулятор роста ИМК на развитие корней подвоев яблони. Средняя длина корней у всех изучаемых подвоем при применении ИМК в питательной среде Мурасиге-Скуга (MS) варьировала от 2,2 до 5,5 см в зависимости от генотипа подвоя.

У статті розглянуто новітні системи бізнес інтелекту (Business Intelligence) для оптимізації
функцій управляння підприємством, які дозволяють використовувати та обробляти великі
обсяги інформації, не тільки для корпоративного рівня, але й середнього та малого бізнесу.
Управління підприємством - це спосіб ведення та контролю бізнесу, процесів, інформаційних
та ІТ можливостей, пропозицій систем та послуг, ресурсів та діяльності підприємства. У період
суцільної диджиталізації пріоритетними рішеннями керівництва стає впровадження цифрових
технологій у всі підрозділи підприємства. Тому використання систем Business Intelligence має
розв’язувати задачі збору інформації на рівнях підрозділів, кумуляції необроблених даних у
сховищах даних та аналітичну обробку даних для певних управлінських завдань з урахуванням
явної та прихованої інформації

Організація системи обслуговування грає ключову роль визначенні маркетингової політики.
Ефективне обслуговування передбачає високий та якісний рівень гарантійного обслуговування,
надання клієнтам послуг, довгострокові гарантії. Чим краще експортер зможе організувати
обслуговування, тим сильніше його становище на світовому ринку.
Транспортні послуги є одним із найважливіших елементів у розвиток всієї системи міжнародної торгівлі. Створення та розвиток сучасних морських вантажних перевезень багатьма
країнами розглядається як один із основних напрямів забезпечення національної економічної
безпеки та суверенітету. Контейнеризація вантажних перевезень, що обслуговуються морським
і наземним транспортом, зробила дешевшим і спрощеним весь ланцюжок перевезень і експедиторських операцій, але заклала основу для подальшого розвитку єдиного міжнародного
правового поля в галузі транспортного сервісу Міжнародні відносини між країнами завжди
зумовлювалися пересуванням товару між ними. Саме собою формування транспортних систем відбувалося рамках національних економічних систем. Спеціалізація транспорту виявляється у розподілі існуючих та створенні нових галузей промисловості з однорідним продуктом
або послугою, а також у розподілі праці між підприємствами галузі. Слід зазначити значимість міждержавної координації у розвитку транзитного транспорту. Подібні багатосторонні
угоди усувають митні бар›єри, забезпечують велику транспортну безпеку, що стимулює економічну співпрацю між країнами та створює передумови для розвитку інтеграційних процесів. У
світі регіональні транспортні мережі інтегровані у великі мережі міжрегіонального масштабу,
пов›язуючи основні ринки та виробничі центри.
На сучасному етапі, де існує тенденція все до більшої глобалізації, а країни, що розвиваються, прагнуть зміцнити свої позиції на світовому ринку, саме економічні фактори є основою
для впливу економічно більш розвинених держав на світову політику, формування військового
і політичного потенціалу країн світу. І в цій зв›язці наявність нових транспортних систем і транспортних коридорів одна із найважливіших економічних ресурсів.
Наявність транспортних коридорів створює нові можливості політичного впливу держав.
При розвитку перевезень по транспортним системам, що проходить через територію України,
необхідно враховувати, що держави, профспілки та великі транспортні компанії перебувають у
жорсткій конкуренції, пропонуючи свої МТК та розвиваючи їх конкурентні переваги.
