Authors: Graetz Christian , Düffert Paulina , Heidenreich Ralf , Seidel Miriam , Dörfer Christof E.
Published: May 2021

Objective/aim

To identify small particle concentrations (eight categories: ≤0.1 µm × ≤5.0 µm) induced by aerosol-generating procedures (AGPs; high-speed tooth preparation, ultrasonic scaling; air polishing) under high-flow suction with a 16-mm intraoral cannula with and without an additional mobile extraoral scavenger (EOS) device during student training.

Materials and methods

Twenty tests were performed (16.94 m2room without ventilation with constant temperature (26.7 (1.1) °C and humidity (56.53 (4.20)%)). Data were collected 2 min before, 2 min during, and 6 min after AGPs. The EOS device and the air sampler for particle counting were placed 0.35 m from the open mouth of a manikin head. The particle number concentration (PN, counts/m3) was measured to calculate ΔPN (ΔPN = [post-PN] − [pre-PN]).

Results

Mean ΔPN (SD) ranged between −8.65E+06 (2.86E+07) counts/m3for 0.15 µm and 6.41E+04 (2.77E+05) counts/m3for 1.0 µm particles. No significant differences were found among the AGP groups (p > 0.05) or between the AGP and control groups (p > 0.05). With an EOS device, lower ΔPN was detected for smaller particles by high-speed tooth preparation (0.1–0.3 µm;p < 0.001).

Discussion

A greater reduction in the number of smaller particles generated by the EOS device was found for high-speed tooth preparation. Low ΔPN by all AGPs demonstrated the efficacy of high-flow suction.

Conclusions

The additional use of an EOS device should be carefully considered when performing treatments, such as high-speed tooth preparation, that generate particularly small particles when more people are present and all other protective options have been exhausted.
Deciphering the spectral collapse in two-photon Rabi model
Authors: Lo C. F.
Published: May 2021

In this communication, based upon a squeezed-state trial wave function, we have performed a simple variational study of the spectral collapse of the two-photon Rabi model. Our analysis indicates that the light-matter interaction and the spin-flipping effectively constitute two competing impacts upon the radiation mode. Whilst the former tries to decrease the radiation mode frequency, the latter may counteract or reinforce it, contingent upon the state of the atomic system. The light–matter interaction appears to dominate the frequency modulation as its coupling strength goes beyond the critical value, leading to the emergence of the spectral collapse. However, at the critical coupling the dominance of the light–matter interaction is not complete, and incomplete spectral collapse appears. The extent of incomplete spectral collapse is found to depend upon the energy difference between the two atomic levels as well.
Whole transcriptome RNA-seq reveals key regulatory factors involved in type 2 diabetes pathology in peripheral fat of Asian Indians

Published: May 2021

The prevalence of Type 2 Diabetes has reached an epidemic proportion particularly in south Asian countries. We have earlier shown that the anatomical fat distribution, termed ‘thin fat phenotype’ in this population indeed plays a major role for their T2D-predisposition it is indeed the sick fat or adiposopathy, which is the root cause of metabolic syndrome and diabetes and affects both—peripheral, as well as visceral adipose tissue compartments. In present study, we have attempted to unravel the altered regulatory mechanisms at the level of transcription factors, and miRNAs those may likely accounts to T2D pathophysiology in femoral subcutaneous adipose tissue. We prioritized transcription factors and protein kinases as likely upstream regulators of obtained differentially expressed genes in this RNA-seq study. An inferred network of these upstream regulators was then derived and the role of TFs and miRNAs in T2D pathophysiology was explored. In conclusions, this RNS-Seq study finds that peripheral subcutaneous adipose tissue among Asian Indians show pathology characterized by altered lipid, glucose and protein metabolism, adipogenesis defect and inflammation. A network of regulatory transcription factors, protein kinases and microRNAs have been imputed which converge on the process of adipogenesis. As the majority of these genes also showed altered expression in diabetics and some of them are also circulatory, therefore they deserve further investigation for potential clinical diagnostic and therapeutic applications.

Primary vasopressor efficacy of epinephrine during cardiopulmonary resuscitation (CPR) is due to its α-adrenergic effects. However, epinephrine plays β1-adrenergic actions, which increasing myocardial oxygen consumption may lead to refractory ventricular fibrillation (VF) and poor outcome. Effects of a single dose of esmolol in addition to epinephrine during CPR were investigated in a porcine model of VF with an underlying acute myocardial infarction. VF was ischemically induced in 16 pigs and left untreated for 12 min. During CPR, animals were randomized to receive epinephrine (30 µg/kg) with either esmolol (0.5 mg/kg) or saline (control). Pigs were then observed up to 96 h. Coronary perfusion pressure increased during CPR in the esmolol group compared to control (47 ± 21 vs. 24 ± 10 mmHg at min 5, p < 0.05). In both groups, 7 animals were successfully resuscitated and 4 survived up to 96 h. No significant differences were observed between groups in the total number of defibrillations delivered prior to final resuscitation. Brain histology demonstrated reductions in cortical neuronal degeneration/necrosis (score 0.3 ± 0.5 vs. 1.3 ± 0.5, p < 0.05) and hippocampal microglial activation (6 ± 3 vs. 22 ± 4%, p < 0.01) in the esmolol group compared to control. Lower circulating levels of neuron specific enolase were measured in esmolol animals compared to controls (2[1–3] vs. 21[16–52] ng/mL, p < 0.01). In this preclinical model, β1-blockade during CPR did not facilitate VF termination but provided neuroprotection.

Published: May 2021

Until recently, brain networks underlying emotional voice prosody decoding and processing were focused on modulations in primary and secondary auditory, ventral frontal and prefrontal cortices, and the amygdala. Growing interest for a specific role of the basal ganglia and cerebellum was recently brought into the spotlight. In the present study, we aimed at characterizing the role of such subcortical brain regions in vocal emotion processing, at the level of both brain activation and functional and effective connectivity, using high resolution functional magnetic resonance imaging. Variance explained by low-level acoustic parameters (fundamental frequency, voice energy) was also modelled. Wholebrain data revealed expected contributions of the temporal and frontal cortices, basal ganglia and cerebellum to vocal emotion processing, while functional connectivity analyses highlighted correlations between basal ganglia and cerebellum, especially for angry voices. Seed-to-seed and seed-to-voxel effective connectivity revealed direct connections within the basal ganglia—especially between the putamen and external globus pallidus—and between the subthalamic nucleus and the cerebellum. Our results speak in favour of crucial contributions of the basal ganglia, especially the putamen, external globus pallidus and subthalamic nucleus, and several cerebellar lobules and nuclei for an efficient decoding of and response to vocal emotions.

The article discusses the problem of verification and validation of engineering software when solving problems of nonlinear dynamics. The problems of validation and verification are shown on the example of dynamic chaos systems. The results of testing systems are presented. It is shown that in general when solving problems of nonlinear dynamics the characteristics of the developed engineering software are of critical importance. It is also indicated that neglecting this fact leads to irreversible negative consequences, ultimately resulting in the decay of the dynamics of a nonlinear system as well as in the decay of its orbits. The influence of the hardware and a number of aspects of the system and software implementation of the verification and validation systems under study is also shown. The article demonstrates modern approaches to the development of the studied software systems. It is shown that a high-quality software product suggests division into subsystems and stages.

Published: May 2021

Eco-industrial park is the new trend in developing sustainable industrial zones. In Vietnam, the concept of ‘eco-industrial park’ has gained its popularity in the last decade; yet there remain many obstacles in actualizing this model. One of the main reasons is the lack of a criteria set for building eco-industrial parks that fits Vietnamese situation. We analyzed criteria for building eco-industrial parks in other countries in order to compare with current criteria in Vietnam. Suggestions for establishing a criteria set for building eco-industrial parks in Vietnam were discussed.

Published: May 2021

The authors examined the key components of In moden post – reform conditions when the organization of the use of agricultural land is carried out without land management project documentation and relevant recommendations, in conditions of significant pressure from industrial and urban development, this is primarily the main reason for the decline in soil fertility and the development of degradation processes, a departure from the classical sustainable agricultural land use, formed on the principles of land management and the laws of nature management [1- 4]. In the process of functioning, once-stable land uses have not changed borders for decades, which indicates a rational overall size of agricultural land use, when all three production factors: “labor”, “land” and “capital” are in full compliance with each of them, that is, harmonization, rationalization and greening [5, 6]. This harmonization eliminates the presence of such disadvantages as: far-earth, cross-stripe, wedging, etc., creates conditions for the rationai organization of the use of agricultural land [2, 5, 6].

Published: May 2021

The existing procedure for regulating property relations, built on the basis of the concept of market equilibrium, requires updating on the basis of a mechanism for preparing and making fair decisions, taking into account the wide opportunities for analysis through the use of artificial intelligence. We continue and develop the presented research by describing the implementation of the decision-making preparation mechanism based on the creation of a financial digital twin of the marine infrastructure property complex. The purpose of this study is to consider options and digital mechanisms for making management decisions on the development of infrastructure property complexes that are justified from an economic point of view, as well as from the point of view of public efficiency. The following tasks are solved: define a regional marine property complex as a type of infrastructure property complex; create criteria for evaluating the effectiveness of the regional marine infrastructure property complex; describe the implementation of the mechanism for preparing for decision-making based on the creation of a financial digital double of the research object. Mechanisms of support for managerial decision-making using artificial intelligence based on neural network construction are considered. The scientific novelty lies in the fact that the study offers an effective mechanism for preparing and making decisions, implemented on the basis of creating a financial digital double of the marine infrastructure property complex.
Geoecological aspects of the underground erosion development in loessial massifs of Uzbekistan
Authors: Lavrusevich Andrey , Trofimets Lyubov , Mamina Dinya , Stepanova Elena
Published: May 2021

The problem of the development of the underground erosion is considered ion the article. The most brightly the underground erosion is shown in the massifs of the loessial breeds, which are widely developed in Uzbekistan. This phenomenon of consequences of the underground erosion development is described in science as the term “loessial pseudo-karst”. The loessial pseudo-karst have received the greatest spread and development in places of an active technogenesis since the second half of the XX century. Besides the territories connected with civil, industrial and hydrotechnical engineering the loessial pseudo-karst develops actively in the connection with active irrigation of the massifs formed with the loessial breeds. In case of not dosed water supply for the irrigation of agricultural grounds and the subsequent uncivilized dumping of surplus of water there is an extremely fast development of a loessial pseudo-karst (a day and even several hours). The negative consequences of the development of the underground erosion in loessial massifs lead to the violation of fragile balance of the natural and technical geosystems (NTG) and their conclusion from the condition of metastable balance. When forming pseudo-karst sinkholes near settlements, their unreasoned elimination by filling happens generally at the expense of solid and liquid household waste that considerably accelerates process of destruction of the massif, due to the impact on the loessial breeds of aggressive infiltrate. In case of active development of the underground erosion there is a final fracture of the loessial massif and formation of so-called pseudo-karst “bedlend”, that is sites where any economic activity is impossible. There are considerable economic, ecological and quite often social damages. It is easier to prevent a loessial pseudo-karst, than to fight against after its development has begun. The lack of due consideration to this promptly developing process annually causes the necessity of recultivation of the soil massifs broken by an underground erosion (pseudo-karst) or to the conclusion from the crop rotation of the most valuable irrigation lands in arid areas. The qualitative recommendations about the prevention of the development of a loessial pseudo-karst and minimization of damage are made.

Published: May 2021

The growth of the world’s population and the rapid development of the economy are leading to an increase in the demand for agricultural products from year to year. This, in turn, increases the demand for limited natural resources - water and land resources, especially land for agricultural purposes. In such a complex environment, the rational and efficient use of land, increasing productivity by improving the reclamation and fertility of the soil is a requirement of the times. The growing demand for land in society makes it necessary to develop and implement measures to protect land. Land protection is closely related to land control, which is ensured by land control. In this study, the study was conducted in terms of public participation in land control in the field of agricultural land use. At the same time, the foreign experience in the field and the national legal framework of the Republic of Uzbekistan were compared. The article also discussed the goals and objectives of land control. The authors have scientifically and legally studied the participation of the public in land control, the advantages, subjects, objects and forms of public control. The article also examines scientific research on land control and public control. As a result of studying the system of legislation of the Republic of Uzbekistan on land control, the authors systematized the procedures aimed at ensuring public participation in the field. Prospects for the application of foreign experience in the implementation of public land control were also considered. In addition, the scientific and theoretical basis for the rational use of land resources and their protection in achieving the strategic goals of agricultural development of the Republic of Uzbekistan for 2030 has been developed.

The main objective of this study was to determine the level of toxic effects of pesticides on the development of immune and endocrine systems in offspring during intrauterine and early postnatal development. During the experiment, preparations containing the pesticide lambda-Cyhalothring (LCP) and fipronil were injected into white laboratory rats during pregnancy and lactation. The study was carried out using electron microscopy and morphological and biochemical studies. From the results of this study, it is concluded that the toxic effect of pesticide exposure during pregnancy and lactation is manifested by stunted growth of the thyroid gland (lymph nodes), thymus, lymph node and spleen development. Cell proliferation and apoptosis caused by direct toxic effects of drugs, developed hypothyroidism, oxidative stress reactions in both mother-nature and offspring are the main cause of toxic effects of industrial pesticides on the immune and endocrine systems. It follows from the data obtained that early detection of hypothyroidism and oxidative stress states in pregnant women and infants and then their correction with drugs is an important aspect of public health.

Authors: Tufliev Nodirbek , Akhmedjanov Sherzod
Published: May 2021

Diversity of natural climatic conditions in Central Asia leads to the mass development and spread of cross-border pests, especially locusts, in these provinces. This requires monitoring studies to determine the species composition of endangered locusts that migrate from one state to another in transboundary areas and among them the most major pest species that pose a threat to agricultural crops. Therefore, this article identifies the species composition of locusts found in the border areas of Uzbekistan with neighboring republics of Tajikistan, Kyrgyzstan and Turkmenistan, including harmful species. The results of the use of geographic information system (GIS) technologies in monitoring the spread of locusts in the cross-border areas of Surkhandarya, Kashkadarya, Jizzakh and Namangan provinces are presented.

Impact of sustainable development goals on strategic planning in the Russian regions
Authors: Mazein Artem
Published: May 2021

Achievement by states of the Sustainable Development Goals proclaimed by the UN in 2015 requires appropriate governance. The most appropriate method is strategic planning. A large number of strategic planning documents have been adopted in Russian regions. The author notes that the words “plan,” “forecast,” “strategy,” “program” are found in the names of 950 thousand legal acts of the regional and municipal levels. This is about 9% of their total. In this article, the author examines regional legislation for the inclusion of ideas on sustainable development. The author uses methods of analysis, synthesis, generalization, and system-structural method. The study results confirm that the regulation of sustainable development is reflected primarily in strategic planning documents. The author shows that references to sustainable development in 88% of cases are found in strategic planning documents. Strategic planning documents are adopted following the federal law “On strategic planning in the Russian Federation". However, the article concludes that the approaches to the formation of strategic planning documents are different. The author demonstrates that similar strategic documents are adopted by various bodies and for different periods. For example, only 46 out of 85 regional development strategies have been adopted until 2030; the rest have different implementation dates. The author concludes that the difference in approaches is permissible, and the intersection of strategic measures in various documents of the same level must be timely excluded.

At present in Russia there is no unified generally accepted concept for assessing the results of sustainable development of industrial regions. In the paper, based on a review of Russian and foreign research, the authors have made an attempt to generalize modern concepts, and also present their vision of assessing the results of industrial regions sustainable development. The urgency of the research is due to the need for the practical implementation of the sustainable development concept. The authors see the essence of sustainable development of industrial regions in an organization of current activities and meeting the needs of modern residents of the region, which would not harm natural environment. It has been noted that large industrial plants, evaluating the results of sustainable development, are beginning to use foreign methods. As the influence of large enterprises forming an industrial cluster in the region on the economy, society and natural environment is great, the authors consider it expedient to use their developments in the field of assessing the results of sustainable development. To assess the results of sustainable development of industrial regions, it has been proposed to use 33 indicators of GRI Standards which include economic, environmental and social “thematic standards”.
Arctic region and arctic cities VS sustainable region and smart cities

Published: May 2021

Existing crises of arctic sustainable development and continuous increase of the VUKA world tendencies require urgent reconsidering economic and political models in the Arctic region, considering modern global trends, technological, political, socio-cultural conditions, and Russian national development goals. One of the key global trends is rapid urbanization and “smart cities” as a solution to the increasing problems of urban sustainable development. The level of urbanization in the Arctic zone of the Russian Federation exceeds the average for the whole world. In this research, we focus on the problem of arctic sustainable “smart cities”. We analyzed existing approaches and concepts of “Smart City” and classified them into three main groups: system (complex) approach, technological approach, and socio-cultural approach. We showed different basic axiomatics and priorities in these approaches, which logically result in different social consequences. We suggested the socio-cultural approach as most relevant to the humanistic sense of developing smart cities and purposes of sustainable development. In particular, implying this approach in developing Arctic smart cities will allow using Arctic advantages and wealth for long-perspective human development and increasing the quality of life of Arctic people.

Authors: Zabelina Irina
Published: May 2021

Using the most popular measures of inequality and recent statistical data, the authors estimate interregional inequalities in Russia. The specific aim of this study is to identify inequality in well-being indicators, which were calculated using a multiplicative model based on the A. Sen extended function. Our calculations have revealed that there is a significant interregional differentiation in the social well-being level. The environmentally adjusted well-being exhibits higher levels of inequality than the indicator that does not take into account the environmental component. The paper shows that from 2008 to 2018 the gaps between Russian regions had in some cases increased.

It should be noted that Russian and foreign authors characterize the concept of business success and methods of its evaluation in different ways, on the basis of which we have adopted an attempt to consciousness of a completely new approach to this issue. The paper provides examples based on the financial statements of the two major organizations in Chelyabinsk, showing the parallel between our theoretical assumptions based on economic and mathematical methods and existing factors of the internal and external environment. The authors note that this article was prepared in connection with the weak development of researchers earlier on this issue from the position of economic and mathematical methods and existing theories of other exact sciences. For example, the study of organizations using bifurcation theory is almost entirely absent in modern literature and scientific publications. This work will clarify the definition of business success and explore new approaches to its assessment
