Published: July 2021

Understanding the mechanism for heat tolerance is important for the hot pepper breeding program to develop heat-tolerant cultivars in changing climate. This study was conducted to investigate physiological and biochemical parameters related to heat tolerance and to determine leaf heat damage levels critical for selecting heat-tolerant genotypes. Seedlings of two commercial cultivars, heat-tolerant ‘NW Bigarim’ (NB) and susceptible ‘Chyung Yang’ (CY), were grown in 42 °C for ten days. Photosynthesis, electrolyte conductivity, proline content were measured among seedlings during heat treatment. Photosynthetic rate was significantly reduced in ‘CY’ but not in ‘NB’ seedlings in 42 °C. Stomatal conductivity and transpiration rate was significantly higher in ‘NB’ than ‘CY’. Proline content was also significantly higher in ‘NB’. After heat treatment, leaf heat damages were determined as 0, 25, 50 and 75% and plants with different leaf heat damages were moved to a glasshouse (30–32/22–24 °C in day/night). The growth and developmental parameters were investigated until 70 days. ‘NB’ was significantly affected by leaf heat damages only in fruit yield while ‘CY’ was in fruit set, number and yield. ‘NB’ showed fast recovery after heat stress compared to ‘CY’. These results suggest that constant photosynthetic rate via increased transpiration rate as well as high proline content in heat stress condition confer faster recovery from heat damage of heat-tolerant cultivars in seedlings stages.

Published: July 2021

To assess good prognostic factors of Trabectome surgery in primary open-angle glaucoma (POAG), clinical records of patients with POAG who underwent Trabectome surgery with/without cataract surgery as the first additive therapy to eye drops between January 2015 and March 2018 were retrospectively reviewed. Overall, data of 79 eyes (79 patients; 50 men; mean age, 68.0 years) up to postoperative 24 months were analyzed. Their mean intraocular pressure (IOP) was 20.4 ± 6.0 mmHg at baseline. Forty-two eyes (53.2%) achieved an IOP < 15 mmHg and ≥ 20% reduction from baseline without additional treatments. Phakic eyes had a better survival probability than pseudophakic eyes after adjusting for age, sex, baseline IOP, best-corrected visual acuity, and eye drop score (hazard ratio 3.096; 95% confidence interval [95% CI] 1.367–7.013; P = 0.007). Phakic eyes treated with combined Trabectome and cataract surgeries (mean survival time, 22.250 months; 95% CI 17.606–26.894) had a better survival probability than pseudophakic eyes treated with Trabectome surgery only (mean survival time, 12.111 months; 95% CI 8.716–15.506; P = 0.009) after the adjustment. Among the eyes treated with Trabectome surgery only, phakic eyes required significantly less additional treatments than pseudophakic eyes (P = 0.04). Trabectome surgery may be indicated for phakic eyes with POAG in addition to eye-drop therapy.

Diabetes is one of the largest global health problems and exhibits a constantly increasing trend. A series of nationwide hospital-based cross-sectional surveys of clinical outcomes was performed annually from 2011 to 2015 and 2018 among patients with type 2 diabetes aged ≥ 20 years receiving medical care for at least 12 months. A two-stage stratified cluster that was proportional to the size sampling technique was used to select a nationally and provincially representative sample of patients with type 2 diabetes in Thailand. A total of 186,010 patients with type 2 diabetes were enrolled in the study from 2011 to 2018. The prevalence of adequate glycemic control (hemoglobinA1c level < 7.0%) among patients with type 2 diabetes were estimated to be 34.5% (95%CI 33.8–35.2%) in 2011, 33.0% (95%CI 32.4–33.6%) in 2012, 34.7% (95%CI 34.1–35.4%) in 2013, 35.5 (95%CI 34.9–36.1%) in 2014, 35.6 (95%CI 35.0–36.2%) in 2015, and 35.6% (95%CI 35.0–36.2%) in 2018, respectively (p for trend < 0.001). Independent factors related to poor glycemic control (hemoglobinA1c ≥ 7%) were being female, younger aged, living in the northeastern region, received care form hospitals lower than regional level, under universal health coverage scheme, greater duration of diabetes, higher body mass index level and absence of hypertension comorbidity.
Mitofusion is required for MOTS‐c induced GLUT4 translocation
Authors: Bhullar Khushwant S. , Shang Nan , Kerek Evan , Wu Kaiyu , Wu Jianping
Published: July 2021

MOTS‐c (mitochondrial ORF of the twelve S-c) is a 16-amino-acid mitochondrial peptide that has been shown to counter insulin resistance and alleviate obesity in vivo. However, the mechanisms involved in the pharmacological action of MOTS-c remain elusive. Based on the ability of MOTS-c to improve insulin resistance and promote cold adaptation, we hypothesized that MOTS-c might play a role in boosting the number of mitochondria in a cell. We found that treatment of mammalian cells with MOTS‐c increased protein levels of TFAM, COX4, and NRF1, which are markers for mitochondrial biogenesis. However, flow cytometry analysis using MitoTracker Green revealed a sharp reduction in the mitochondrial count after MOTS‐c treatment. We then anticipated possible synchronized activation of mitofusion/mitochondrial fusion by MOTS‐c following the onset of mitochondrial biogenesis. This was confirmed after a significant increase in protein levels two GTPases, OPA1, and MFN2, both vital for the fusion of mammalian mitochondria. Finally, we found that inhibition of the two GTPases by TNFα abrogated the ability of MOTS‐c to prompt GLUT4 translocation and glucose uptake. Similar results were obtained by siRNA KD of MFN2 as well. Our results reveal for the first time a pathway that links mitofusion to MOTS-c-induced GLUT4 translocation.

Published: July 2021

Regional and local climate change depends on continentality, orography, and human activities. In particular, local climate modification by water reservoirs can reach far from shore and downstream. Among the possible ecological consequences are shifts in plant performance. Tree-ring width of affected trees can potentially be used as proxies for reservoir impact. Correlation analysis and t-tests were applied to climatic data and tree-ring chronologies of Pinus sylvestris L. and Larix sibirica Ledeb. from moisture-deficit habitats in the intermontane Khakass-Minusinsk Depression, to assess modification of climate and tree growth by the Krasnoyarsk and Sayano-Shushenskoe Reservoirs on the Yenisei River. Abrupt significant cooling in May–August and warming in September-March occurred after the launch of the turbines in dams, more pronounced near the Sayano-Shushenskoe dam (up to – 0.5 °C in summer and to + 3.5 °C in winter) than near the Krasnoyarsk Reservoir headwaters (– 0.3 °C and + 1.4 °C). Significant lengthening of the warm season was also found for temperature thresholds 0–8 °C. Shifts of seasonality and intensity occurred in climatic responses of all tree-ring chronologies after development of water reservoirs. Patterns of these shifts, however, depended on species-specific sensitivity to climatic modification, distance from reservoirs, and physiographic regions. Mitigation of climate continentality and extremes by reservoirs appears to have offset possible negative effects of warming on tree growth.

Published: July 2021

Both electrical properties and biomarkers of biological tissues can be used to distinguish between normal and diseased tissues, and the correlations between them are critical for clinical applications of conductivity (σ) and permittivity (ε); however, these correlations remain unknown. This study aimed to investigate potential correlations between electrical characteristics and biomarkers of breast cancer cells (BCC). Changes in σ and ε of different components in suspensions of normal cells and BCC were analyzed in the range of 200 kHz–5 MHz. Pearson's correlation coefficient heatmap was used to investigate the correlation between σ and ε of the cell suspensions at different stages and biomarkers of cell growth and microenvironment. σ and ε of the cell suspensions closely resembled those of tissues. Further, the correlations between Na+/H+ exchanger 1 and ε and σ of cell suspensions were extremely significant among all biomarkers (pε < 0.001; pσ < 0.001). There were significant positive correlations between cell proliferation biomarkers and ε and σ of cell suspensions (pε/σ < 0.05). The microenvironment may be crucial in the testing of cellular electrical properties. ε and σ are potential parameters to characterize the development of breast cancer.
Year-round high abundances of the world’s smallest marine vertebrate (Schindleria) in the Red Sea and worldwide associations with lunar phases

Published: July 2021

Very little is known about the ecology and biology of the smallest marine vertebrates, fishes in the genus Schindleria. Even though over half of named Schindleria species have been identified in the Red Sea, the collection of only very few specimens has been documented. Here, we assessed abundance patterns of nearly two thousand Red Sea long dorsal fin (LDF) adults and found evidence for putative seasonal and spatial differences, likely related to differing habitat and environmental conditions. The highest abundances were outside local seasonal temperature extremes and decoupled from peaks of coral reef fish recruitment. We also found evidence for global trends in abundances related to lunar cycles using our Red Sea data and that from a recently published large collection of specimens from the DANA Expedition (1928–1930). The abundance of adult LDF Schindleria in relation to lunar phases differed significantly, with most Schindleria caught outside the full moon, and mostly during the new moon in the Red Sea and the 3rd quarter moon in the DANA collection. We further suggest that the abundances of Schindleria at coral reefs may be related to reproductive cycles and that these cycles may be timed with the moon as back-calculations of hatch dates from otoliths from the Red Sea significantly resulted after the new moon, making Schindleria the fastest-lived coral reef fish with the shortest generation times. Schindleria could be the most numerous coral reef fish in the world, for which we encourage increased research.
Interpretable and parameter optimized ensemble model for knee osteoarthritis assessment using radiographs
Authors: Bany Muhammad Mohammed , Yeasin Mohammed
Published: July 2021

Knee osteoarthritis (KOA) is an orthopedic disorder with a substantial impact on mobility and quality of life. An accurate assessment of the KOA levels is imperative in prioritizing meaningful patient care. Quantifying osteoarthritis features such as osteophytes and joint space narrowing (JSN) from low-resolution images (i.e., X-ray images) are mostly subjective. We implement an objective assessment and quantification of KOA to aid practitioners. In particular, we developed an interpretable ensemble of convolutional neural network (CNN) models consisting of three modules. First, we developed a scale-invariant and aspect ratio preserving model to localize Knee joints. Second, we created multiple instances of "hyperparameter optimized" CNN models with diversity and build an ensemble scoring system to assess the severity of KOA according to the Kellgren–Lawrence grading (KL) scale. Third, we provided visual explanations of the predictions by the ensemble model. We tested our models using a collection of 37,996 Knee joints from the Osteoarthritis Initiative (OAI) dataset. Our results show a superior (13–27%) performance improvement compared to the state-of-the-art methods.

Authors: Aung Htet Ye , Boyarintsev Alexander , Stepanov Sergey , Shoustikov Andrei
Published: July 2021

Due to the ever-increasing demand of the world economy for aluminum, its alloys and compounds, the production of this metal is increasing annually throughout the world. This leads to an increase in the industrial production of alumina, which is obtained from bauxite ore in the Bayer process. After recovering the bulk of the aluminum from the bauxite ore, there remains a residue which is highly alkaline toxic waste, which is also called bauxite residues (tailings) or red mud (RM). About 140-150 million tons of RM are produced annually and almost 4 billion tons have already been accumulated. At the moment, the problem of RM recycling and the development of effective and cost-effective approaches to their reprocessing is extremely urgent. Reducing RM affects economic, environmental, social areas and is a prerequisite for the sustainable development of nature and society. Despite active scientific research and efforts to develop and optimize various methods for RM recycling and reprocessing, the problem of an annual increase in their volumes around the world remains unresolved. Recently, promising and efficient processes have been proposed that allows for the complex reprocessing of RM with the extraction of a number of valuable liquid products that may be in demand in various fields of industry. This allows to focus on large-scale disposal of RM and can be a solution to the problem of handling these industrial wastes. The article considers the main current trends in the field of management of various types of RM with a focus on complex reprocessing and zero waste concepts.

Published: July 2021

A significant number of milk processing companies all over the world confront the challenge of whey recycling. To date, the processing of milk results in a considerable amount of waste products, which can be used in core production processes, for the output of additional products and can help neutralize harmful effects of milk processing waste waters on the environment. This factor emphasizes the relationship between food and environment. The extraction of water from cheese and curd whey in the manufacture of concentrates gives a solution to one of the challenges facing the dairy industry – the processing of secondary dairy raw resources. Whey concentrates have certain advantages because they are long-shelf-life and easy-to-transport products of high nutritional and biological value. Several studies have assessed process flow factors of whey dehydrating in the manufacture of whey concentrates. The research was carried out using an experimental unit of a vacuum dryer with the thermal radiation power supply. The concentrates with a percentage of dry substances ranging from 11 to 30 % were produced. The important outcomes to emerge from the study are data on the dynamics of vacuum-induced water extraction from cheese and curd whey, its appropriate modes, as well as regularities and specifics of water removal. The quality of concentrates was assessed according to key parameters. The organoleptic properties of sample concentrates met all criteria quite sufficiently, being similar to input parameters. Whey concentrates with a mass fraction of dry substances from 11 to 30.0 % are recommended to use in recipe compositions of fresh and fermented whey-containing drinks. IR-rays represent a good alternative to conventional thickening and drying processes of raw materials at high processing temperatures. The properties of input raw materials remain unaffected owing to non-destructive temperature modes of the vacuum dryer.

Published: July 2021

This article studies the technology of growing seedlings of different varieties of apples at vegetatively propagated low-growing M-IX and medium-sized MM109 grafting points and provides scientifically based data. Grafting the upper-grafted bud by removing the wooden part resulted in a significant increase in its grip. When apple varieties were grafted to M-IX grafting point without removal of the wood part, the total amount of preserved upper-grafted buds ranged from 76% to 80% by variety, while in the experimental variant of grafting without wood, this figure ranged from 85% to 95% and observed to vary in this interval. When the bud graft is made to the root collar of the grafting point, this figure does not exceed 61.7-68.6% by variety. When the bud was grafted 10 cm above the root collar, it was found to be in the range of 67.5 to 75.9%, respectively.
Key indicator-based information system for environmental risk accounting and analysis at organizations
Authors: Kostyunina Tatyana
Published: July 2021

The paper presents a method of designing an information system for environmental risk accounting and analysis at organizations. The environmental approach in the field of production is becoming more and more relevant. It calls for accounting and assessing various types of environmental risks accompanying the activity of an organization. However, risk accounting, analysis and assessment are not possible without information support or corresponding information systems. Therefore, the issue considered in this paper is highly topical. Algorithms of environmental risk accounting and analysis are based on the method of key indicators. Using a key indicator-based information system, it is possible to automate the collection of data on events related to the environmental safety of an organization. During the design of such an information system, we developed interfaces of the main actors (user, risk coordinator, risk manager, expert, and administrator). We also implemented a data management module, a decision-making module, and a system administration module. In the long run, the system can serve as a basis for integrated environmental safety management at organizations.

Recently, different methods of object classification using training datasets is actually. One of these methods is naive Bayesian classifier. Class of objects can consist of low number of elements. Such class is called poor class. In this paper we consider classification problem in poor class. Logical classifier doesn’t work in this case. Metric classifier can give good results if and only if there are quite dense set of metrically nearby classified objects in neighborhood of the considering object. Bayesian classifier reevaluates all hypotheses about belonging of the object to certain class. Therefore, Bayesian classifier can solve this classification problem. For example, we considered classic problem of bank scoring. This scoring is based on two criteria. Classified object has two belonging hypotheses. We can apply such reasoning for more difficult cases.

Published: July 2021

The inspection of reinforced concrete catenary supports is a time-consuming process that necessitates a lot of time to inspect the entire fleet of supports. A large number of supports with a service life of more than 40 years require intensive monitoring and condition forecasting, which can inevitably lead to high economic costs for the work of the catenary electro-mechanics. The introduction of special technical tools to collect and process measurements could solve this problem and allow the planning of a replacement schedule for the supports based on their actual damage. The article discusses the basic factors affecting the load-bearing capacity of rein-forced concrete supports, the main damages occurring, and the procedure for carrying out inspections and assessing the current condition of the supports.
Transport infrastructure indicators for assessing the social comfort of the urban environment
Authors: Martynova Natalia , Budarova Valentina
Published: July 2021

Cities are a complex social institution. A special feature of cities is the development of engineering and transport infrastructure. In this article, to assess the state of the urban agglomeration, the transport system of the city is considered as an indicator of social comfort. As part of the support, control and management of the urban environment, administrative authorities use information technologies that are implemented using geographical information systems (GIS). These GIS take into account all indicators of social comfort, which are based on spatial data about the urban environment. From this, we present the concept of an urban environment data management model for public authorities. The model is based on geoinformation systems. Since the geoinformation analysis allows you to create thematic maps of the urban environment with their subsequent assessment and calculation of indicators of social comfort. For this purpose, an analysis algorithm is presented for the main indicators of transport infrastructure assessment. Thus, this study provides an opportunity to assess the state of the city model and set goals for the development of urban transport networks to increase the level of social comfort of the population.
Optimization of the support structure of a multipurpose machine tool
Authors: Yagopolskiy Aleksandr , Tutukin Dmitry , Andryukhin Nikolay , Ivanov Dmitry
Published: July 2021

Modern manufacturers of multipurpose machining centers design and manufacture equipment according to the criterion of maximum rigidity and productivity to ensure processing of the maximum range of materials at high accelerated cutting modes. As a result, in most machine-building tasks, the support structure of the machine is unnecessarily rigid due to the production of excessively massive frames and body elements of the machine. These structural elements have high weight and size characteristics, which leads to an increase in inertial loads on the drive feed mechanisms. In serial and mass production, heavy elements of the support structure significantly increase the energy consumption of the machine, while reducing labor productivity. Modern methods of design optimization, together with finite element methods, allow solving the problem of energy efficiency and productivity by modifying the support structures according to the criterion of minimum rigidity in accordance with the boundary conditions of the cutting forces when processing the selected product range.

Authors: Diachenko Svitlana , Buha Volodymyr
Published: July 2021

The article is devoted to the issues of territorial development, the role of local self-government bodies in ensuring the processes of planning and management of territories, the system of administrative control over territorial development. Territorial development has great state importance. The standard of living and income of the population are directly related to the resource, economic, technological potential of the territories and the system of territory management. Thus, the issue of managing territorial development by improving the efficiency of local governments is relevant. The article considers the main functions of local governments at the territorial level. The functional direction of territorial administration at the level of local self-government is regulated by the legal framework. The system of normative-legal regulation of territorial development processes, functioning of local self-government bodies are described in the article. The role of local governments, public authorities and the private sector in the implementation of territorial management policy and the implementation of a system of control over the adoption and effective implementation of management decisions on territorial development. The practical significance of the results obtained in the article is to determine the role of local governments in the system of territorial development. This is necessary to build a clear hierarchical system of territorial management at the level of local entities, regions, the state as a whole. The system will allow to distribute management functions, effectively monitor and control their implementation by introducing administrative control at different levels of implementation of management decisions.

Published: July 2021

The article is devoted to the characteristics of environmental investments in the Russian Federation, which are divided into two types: the first investments are aimed at the development and implementation of environmentally friendly production technologies; the second investments are directed to the commissioning of environmental protection and nature-cleaning fixed assets. Investments of the second type are considered in more detail. The data of modern statistics show the reduction of organizations with special costs, associated with investments in the construction of environmental facilities. The dynamics of “green” investments, their structure by directions and sources of financing are analyzed. Economic methods to stimulate environmental investments of enterprises and increase, targeted government spending on the environment, are proposed. As a result, we can consider that transition is needed from the residual principle of financing environmental protection to a directed increase in targeted government spending.

Published: July 2021

The authors of the article believe that it is important to study the deep essence of the writer’s works in order to understand the period of time that he depicts. D.I. Stakheyev contributed to the development of the genres of sketch and short story as he discussed new subjects and ideas through studying the life of the Russian province. In addition, the value of his works is that they touch upon a wide range of universal problems that are of great importance in our time. The article gives a broader idea of “small” forms of literary works in Russia in the mid-19th century. The interpretation of the images of the provincial merchants created by Stakheyev, the Russian writer of the second half of the 19 century, is of scientific interest to us. To understand the nature of provincial merchants Stakheyev goes his own way: he shows the essence of the merchant class through the problems of fathers and children, of crime and punishment, and of the “golden calf” influence on everyday life. The provincial town, marketplace, forest trade are elements depicting a long-established patriarchal world that is far from civilization and not affected by European style of life. The article was written to be used in the educational process. Studying the works of D.I. Stakheev within the framework of additional education, teachers and students of a modern school can discover pages of Russian literature, that were unknown for them, realize the moral problems that were faced by the previous generations.

Published: July 2021

The article analyzes the factors influencing tax evasion: the value of gross domestic product per capita, tax burden, corruption and openness of information on the use of budgetary funds. The correlation model includes the analysis of two groups of indicators. The first group is indicators of the individual level: education, socio-economic status, attitude to religion, gender, etc. The second group is indicators of the global or national level: GDP per capita, tax burden, the level of corruption in the country, the degree of financial transparency of public finances. The results of the study confirmed the hypothesis that law-abiding tax behavior is largely determined by the openness of information about the use of tax revenues by governments. Disclosure of information on the use of budget funds can become a powerful tool for strengthening the understanding of the legitimacy of the state tax policy, as well as act as a preventive measure to overcome existing facts of tax evasion. Increasing the transparency of public finances will make it possible to reproduce a new level of tax culture, to form an internal agreement of citizens with the fiscal policy of the state.
