Regional aspects of sectoral digitalization : problems and prospects
Purpose: At present, high and sometimes record indicators have been achieved for the individual branches of agricultural production. Further intensive development of agriculture is due to the search for new ways to increase labor productivity and lower production costs which is the main aim of this research. Design/Methodology/Approach: The methodological basis served as a systematic approach, which ensured comprehensiveness and purposefulness. Analytical, abstract-logical, economic-statistical, monographic and experimental research methods were also used in this work to examine problems and prospects of sectoral digitalization. Findings: The agro-industrial complex demonstrates the growth of production indicators and is on the rise. The target indicators, laid down in the Food Security Doctrine, have already been achieved by many indices. To a large extent, it is due to a significant increase in the agro-industrial complex. Practical implications: A proposed platform that would ensure a breakthrough in further technical modernization of production, can be created only if the technologies are improved based on their digitalization and orientation towards a specific consumer. Originality/Value: The pin-point introduction of digital technologies in agricultural production confirms the high efficiency of the full innovative technical modernization. The proposed digital transformation of management in the agro-industrial complex of Russia is the value of this research with its originality compared to other ideas.peer-reviewe
Spectral and electroluminescent properties of coordination compounds of terbium (III) with ibuprofen (in solid form, chloroform solutions, and polyvinylcarbazole films)
Spectral properties of terbium (III) complexes with composition of TbL3DL, where L is an anion of d,l-2-(4-isobutylphenyl)propanoic acid (ibuprofen) and DL is 2,2′-dipyridyl (Dipy), 1,10-phenanthroline (Phen), or triphenylphosphine oxide (TPPO), have been studied in a solid form, chloroform solutions, and polyvinylcarbazole (PVC) films. It has been demonstrated that, in PVC films, occupation of the emitting level of terbium (III) involves the participation of polymer. The emission decay lifetimes of terbium in the chloroform solutions and PVC films have been measured. The possibility of the appearance of electroluminescence of complexes in PVC films has been studied
Factors of Formation of Business Activity in an Organization in Innovative Conditions
Currently, our country is in the phase of serious qualitative transformations caused by the need for the economy to recover from the crisis caused by the sanctions of Western countries. To achieve this goal, it is necessary to guarantee sustainable economic growth, to ensure stable economic development of all economic entities, in particular to increase their business activity. The task of increasing the business activity of the organization is of particular importance. The competitiveness of companies is steadily declining, which is associated with the unproductiveness of the business management system and the reasons for its formation.This means that it is necessary to develop fresh science-based approaches and directions that meet the task of increasing the business activity of the enterprise
Reduction of hepatotoxicity of nimesulide in mechanochemically obtained composition with disodium salt of glycyrrhizic acid
Nimesulide (NIM) is a nonsteroid anti-inflammatory drug which acts as a selective cyclooxygenase 2 inhibitor and is widely used for acute pain treatment. In medical practice, a large amount of data has been collected describing the effect of NIM on the body, while a hepatotoxic side effect of the drug has been found. The exact mechanisms of such NIM-induced hepatotoxicity largely remain unknown but likely involve the intermediate reaction of its metabolism. Reduction of the hepatotoxic side effect of NIM is an actual problem for pharmacology. The aim of the present research was to evaluate the hepatotoxicity of the mechanochemically obtained composition of NIM with glycyrrhizic acid disodium salt (Na2GA) compared to pure NIM and a physical mixture of NIM with Na2GA. Material and methods. CD-1 mice were orally administered for 14 days: 1 group – mechanochemical composition NIM/Na2GA (1:10, m/m) at a dose of 1650 mg/kg; 2 group – physical mixture of NIM with Na2GA (1:10, m/m) at a dose of 1650 mg/kg; 3 group – pure NIM at a dose of 600 mg/kg (which pharmacokinetically corresponds to 1650 mg/kg of NIM/Na2GA); 4 group – vehicle (distilled water). The liver damage was assessed using histological studies and enzymatic activity of the alanine aminotransferase and aspartate aminotransferase in blood serum. Results. Histological analysis did not detect any changes in the liver of NIM/Na2GA-treated animals in comparison with a water-treated group. On the opposite, NIM given alone or as a physical mixture with Na2GA induced severe hepatotoxicity in experimental mice. Biochemical analysis of the blood serum revealed that mechanochemical NIM/Na2GA composition significantly reduced activity of the alanine aminotransferase (about 1.5 times) and aspartate aminotransferase (1.3 times) as compared with the pure NIM. Conclusions. The results obtained indicate a high potential for the practical application of the NIM/Na2GA mechanochemical composition
Promising genetic sources for the creation of varieties of durum spring wheat in Western Siberia
The study, expansion and preservation of the genetic diversity of the source material, and its purposeful use in hybridization is the basis for the creation of adaptive varieties of durum spring wheat that are resistant to biotic and abiotic factors of the environment of Western Siberia. The objects of research were samples of durum spring wheat. Over the years of research (2000–2020), about 3 thousand samples were worked out from the world gene pool of various countries and regions: from the collection of the VIR, the gene pool from Mexico (CIMMYT) within the framework of the agreement and cooperation program (2000–2007), from 2000 to the present time under the program of the Kazakh-Siberian Spring Wheat Breeding Network (KASIB), from other scientific institutions of Russia in exchange activities. Using generally accepted techniques, the obtained material was studied for a complex of traits: yield, adaptability, grain quality, resistance to diseases. In the cycle of studying the gene pool from CIMMYT, 50 genotypes were identified in terms of yield at the level of the Omskaja jantarnaja standard, 276 grains by test weight, 131 samples by pasta color, 131 samples by resistance to hard smut, and 112 by resistance to powdery mildew. Almost all samples were not affected by leaf rust. The study set showed high sensitivity to extreme conditions and most forms of interest in quality and disease resistance were low-productive in our environment. In KASIB nurseries, 29 samples were identified in terms of yield and adaptability, 29 samples in terms of grain quality, 21 in terms of resistance to diseases, including 8 resistant to stem rust. In the set of varieties received from the VIR, 15 genotypes were adaptive, 16 had high grain quality, 11 were resistant to stem rust. In the breeding material, 17 samples of the local population resistant to stem rust (6 of them were comprehensively resistant) and 25 race-resistant to Ug99 were identified. The genotypes identified as a result of research are of interest as sources of valuable traits
Контрастная спектральная двухэнергетическая маммография – инструмент точной диагностики онкопатологии на фоне плотной ткани молочной железы
Introduction. Differential diagnosis of some pathological processes in the breast is difficult on the background of dense breast tissue. This often leads to false conclusions and to late diagnosis of breast cancer (BC) or unreasonable biopsy in a benign process. 50% of breast cancers detected less than 12 months after elective mammography were associated with high density of breast tissue. An important advantage of contrast enhanced spectral mammography (CESM) is that it does not depend on the size of the lesions and the X-ray density of the breast tissue. Objective. To compare the diagnostic performance of CESM and digital mammography (DM) in detection of breast cancer in a group of women with dense breast tissue.Materials and methods. The data of 438 patients with suspected breast cancer examined from August 2018 to January 2021 were analyzed in the study. The mean age of women was 50 ± 11 years (from 21 to 86 years). In the study group 154 (35%) malignant and 284 (65%) benign lesions were identified. All lesions were histologically verified. Breast tissue density corresponded to types A and B in 161 patients and corresponded to C and D types in 277 patients according to the ACR classification. 154 cases of breast cancer were identified, including 49 patients with density A and B and 105 patients with density C and D types.Results. Sensitivity, specificity and overall accuracy of DM were 85.7%, 87.3%, 86.8%, respectively. Diagnostic performance of CESM significantly higher than of DM with sensitivity, specificity and accuracy of 96.8% (p < 0.001), 93.3% (p = 0.015), 94.5% (p < 0.001), respectively. CESM had high positive and negative predictive values of 88.7% (p = 0.012) and 98.1% (p < 0.001), which exceeded those of DM – 78.6% and 91.9%, respectively. The diagnostic performance of DM and CESM were comparable in women with normal breast density (types A and B according to ACR), but in patients with high breast density (types C and D according to ACR), CESM was significantly more sensitive in detecting breast cancer.Conclusion. Thus, diagnostic efficiency of CESM in detecting breast cancer significantly higher in comparison with digital mammography.Введение. Дифференциальная диагностика патологических процессов в молочной железе (МЖ) на фоне повышенной маммографической плотности (МП) может быть затруднительной. Это нередко приводит к ложным заключениям и, соответственно, к длительному наблюдению при злокачественной опухоли или необоснованной биопсии при доброкачественном процессе. 50% случаев рака молочной железы (РМЖ), выявленных менее чем через 12 мес после “очередной” маммографии, были связаны с высокой МП. Важным достоинством контрастной двухэнергетической спектральной маммографии (КДСМ) является то, что ее информативность не зависит от размеров образований и МП.Цель исследования: сравнить общую диагностическую эффективность КДСМ и цифровой маммографии (МГ) в выявлении РМЖ у женщин с плотной МП.Материал и методы. В исследовании проанализированы данные 438 пациенток с подозрением на РМЖ. Средний возраст женщин составил 50 ± 11 лет. В исследуемой группе было выявлено 154 (35%) злокачественных и 284 (65%) доброкачественных образования. Была проведена гистологическая верификация всех выявленных образований. У 161 пациентки МП соответствовала ACR А- и В-типам, а у 277 пациенток МП – C- и D-типам согласно классификации ACR. Всего выявлено 154 случая РМЖ, из них у 49 больных МП была ACR А- и В-типов и у 105 пациенток – ACR C- и D-типов.Результаты. При анализе полученных данных чувствительность, специфичность и общая точность МГ составили 85,7, 87,3, 86,8% соответственно. При КДСМ эти показатели достоверно превышали показатели МГ и составили 96,8% (р < 0,001), 93,3% (р = 0,015), 94,5% (р < 0,001) соответственно. КДСМ отличалась высокими показателями прогностической точности положительных и отрицательных результатов – 88,7% (р = 0,012) и 98,1% (р < 0,001), которые превышали таковые при МГ – 78,6 и 91,9% соответственно. Установлено, что диагностические показатели при МГ и КДСМ были сопоставимы у женщин с низкой плотностью МЖ, но у пациентов с высокой плотностью КДСМ была значительно более чувствительной в выявлении РМЖ.Заключение. Таким образом, диагностическая эффективность КДСМ в выявлении рака молочной железы достоверно выше по сравнению с цифровой маммографией

Taming the terminological tempest in invasion science
Standardized terminology in science is important for clarity of interpretation and communication. In invasion science — a dynamic and quickly evolving discipline — the rapid proliferation of technical terminology has lacked a standardized framework for its language development. The result is a convoluted and inconsistent usage of terminology, with various discrepancies in descriptions of damages and interventions. A standardized framework is therefore needed for a clear, universally applicable, and consistent terminology to promote more effective communication across researchers, stakeholders, and policymakers. Inconsistencies in terminology stem from the exponential increase in scientific publications on the patterns and processes of biological invasions authored by experts from various disciplines and countries since the 1990s, as well as publications by legislators and policymakers focusing on practical applications, regulations, and management of resources. Aligning and standardizing terminology across stakeholders remains a prevailing challenge in invasion science. Here, we review and evaluate the multiple terms used in invasion science (e.g. 'non-native', 'alien', 'invasive' or 'invader', 'exotic', 'non-indigenous', 'naturalized, 'pest') to propose a more simplified and standardized terminology. The streamlined framework we propose and translate into 28 other languages is based on the terms (i) 'non-native', denoting species transported beyond their natural biogeographic range, (ii) 'established non-native', i.e. those non-native species that have established self-sustaining populations in their new location(s) in the wild, and (iii) 'invasive non-native' — populations of established non-native species that have recently spread or are spreading rapidly in their invaded range actively or passively with or without human mediation. We also highlight the importance of conceptualizing 'spread' for classifying invasiveness and 'impact' for management. Finally, we propose a protocol for classifying populations based on (1) dispersal mechanism, (2) species origin, (3) population status, and (4) impact. Collectively and without introducing new terminology, the framework that we present aims to facilitate effective communication and collaboration in invasion science and management of non-native species
