The Relationship between Institutional Pressure, Green Entrepreneurial Orientation, and Entrepreneurial Performance—The Moderating Effect of Network Centrality
Authors: Liu Ning , Hu Haiqing , Wang Zhaoqun
Published: September 2022

Most research on institutional pressure focuses on mature enterprises. However, compared with mature enterprises, new ventures are more sensitive to institutional pressure due to their lack of legitimacy. Based on the theoretical path of “environment–strategy–performance”, this study investigated the influence of institutional pressure on entrepreneurial performance as well as the mediating role of green entrepreneurial orientation and the moderating role of network centrality. An empirical analysis based on 288 survey samples from China showed the following: coercive pressure has not only a direct positive impact but also an indirect positive impact on entrepreneurial performance through green entrepreneurial orientation; normative pressure and mimetic pressure positively affect entrepreneurial performance through green entrepreneurial orientation; green entrepreneurial orientation has a positive impact on entrepreneurial performance; network centrality positively regulates the relationships between coercive pressure, mimetic pressure, normative pressure and green entrepreneurial orientation. The paper concluded by highlighting the importance of the conclusions for new ventures to improve their performance as well as for policy makers to optimize the institutional environment for entrepreneurship.

As the world is moving into a sustainable era, achieving zero hunger has become one of the top three Sustainable Development Goals, applying a considerable amount of pressure on the agri-food systems to make decisions contemplating the sustainability dimensions. Accordingly, making effective supply chain decisions holistically while achieving sustainability goals has become a major challenge faced by the present agri-food systems. Thus, to address the challenge, a novel supply chain configuration addressing multiple supply chain decisions to reduce global warming potential (GWP) and post-harvest losses have been presented by taking the banana supply chain in Sri Lanka as a case study. In the proposed approach, farmers have been clustered based on their geo positions using K-Means clustering followed by route planning within clusters using a heuristics approach. Retailer points are catered by assigning to wholesalers optimally modeling as an assignment model and then route planning executed using a heuristic approach. The solution generated from the above approaches has been implemented on a simulation platform to calculate the overall supply chain performance including the transportation component, in terms of the net GWP, post-harvest losses, and lead time including routing operations. Simulated supply chain performance has been compared with the existing system and verified the performance of the proposed supply chain configuration. The suggested configuration has reduced the net GWP by 15.3%, post-harvest loss by 2.1%, lead time by 28.2%, and travel distance by 20.47%. The proposed configuration can be further improved by adding dynamic characteristics to the model.

Published: September 2022

Research on sustainability reporting is becoming increasingly important. Despite the growing body of literature on sustainability reporting, little is known about its past trends and how research areas might evolve in the future. Recognizing and understanding the research trend related to sustainability reporting will enable future researchers to plan and conduct research that is of high interest and impact in terms of both readership and citations. This study examines a large body of literature on environmental, social, and governance (ESG) and sustainability reporting over the last 24 years (1998–2022). The study used bibliometric analysis using VOSviewer software to perform publication trends, citation analysis, and keyword mapping analysis. Data for the analysis was extracted from the online database Scopus on 24 April 2022. Uniquely, the study also employed the Gephi technique, version 0.9.5 of bibliometric analysis, to uncover past ESG research trends and sustainability reports and predict how the content of these study areas will evolve in the future. Based on a sample size of 358 articles, most publications were published in English and in open-access journals. The resultant outcomes of the Gephi technique show that the ESG and sustainability reports can be merged into four clusters. The first cluster points out that corporate social responsibility (CSR) and sustainability reporting now have a stronger social focus as they focus on benefits and environmental impacts. The second cluster focuses on benefits and corporate social responsibility rewards. The third cluster emphasizes the cost of equity and ESG disclosure. Finally, the fourth cluster emphasizes the cost of capital and governance in CSR. The research cluster’s discovery sheds light for future researchers in planning and designing future research focuses.

Published: September 2022

Electric car-sharing (ECS) is an increasingly popular service in many European cities. The management of an ECS fleet is more complex than its thermal engine counterpart due to the longer ”refueling“ time and the limited autonomy of the vehicles. To ensure adequate autonomy, the ECS provider needs high-capacity charging hubs located in urban areas where available peak power is often limited by the system power rating. Lastly, electric vehicle (EV) charging is typically entrusted to operators who retrieve discharged EVs in the city and connect them to the charging hub. The timing of the whole charging process may strongly differ among the vehicles due to their different states of charge on arrival at the hub. This makes it difficult to plan the charging events and leads to non-optimal exploitation of charging points. This paper provides a smart charging (SC) method that aims to support the ECS operators’ activity by optimizing the charging points’ utilization. The proposed SC promotes charging duration management by differently allocating powers among vehicles as a function of their state of charge and the desired end-of-charge time. The proposed method has been evaluated by considering a real case study. The results showed the ability to decrease charging points downtime by 71.5% on average with better exploitation of the available contracted power and an increase of 18.8% in the average number of EVs processed per day.

Published: September 2022

The development of wastewater treatment systems, including competitive methods for nitrogen and phosphorus removal, is focused on intensifying final technological effects with due care taken for economic and environmental concerns. Given the possibility of integrating wastewater treatment processes with biofuel production, the prospective seems to be technologies harnessing microalgal biomass. The present study aimed to verify the feasibility of applying T. subcordiformis genus microalgae as the third stage of the dairy wastewater treatment process and to determine microalgae biomass production effectiveness and hydrogen yield in the biophotolysis process. The study proved that microalgae cultivation with dairy wastewater was nearly 35% less effective compared to that with a chemically pure medium. Nitrogen and phosphorus compounds contaminating wastewater were found to represent an available source of nutrients for T. subcordiformis population. The volume of hydrogen produced ranged from 116 ± 7 cm3 to 162 ± 7 cm3, and the percentage of H2 content in the biogas ranged from 55.4 ± 2.2% to 57.2 ± 4.1%. A significantly higher hydrogen yield per initial biomass concentration, reaching 69 ± 4.2 cm3/go.d.m., was determined in the variant with wastewater accounting for 50% of the culture medium. The respective value noted in the control respirometer was 54 ± 2.1 cm3/go.d.m.

Authors: Wu Mengying , Zhang Lei , Li Wei , Zhang Chi
Published: September 2022

The processes of sustainable development, environmental management, and green performance are inseparable from people’s active participation, and organizational citizenship behavior for the environment (OCBE) has a significant function in promoting that process. We construct a moderated mediating effect model of green management practice by introducing institutional pressure and green emotion into the formation mechanism of OCBE based on neo-institutionalism theory and the theory of planned behavior. Taking matched employees of cross-regional organizations as a sample, we conducted a longitudinal tracking questionnaire survey. The results show a positive correlation between institutional pressure and OCBE, mediated by green emotion. Additionally, the paper discovered that green management practice moderated the relationships between institutional pressure and OCBE, green emotion and OCBE, and institutional pressure and green emotion. Furthermore, green management practice also moderates the strength of the mediating effect of green emotion between institutional pressure and OCBE. The findings provide some guidance for promoting organizational sustainable development and achieving organizational green transformation.

Published: September 2022

With the increasing problem of global warming caused by the massive use of fossil fuels, biomass energy as a renewable energy source has attracted widespread attention throughout the globe. In this paper, we analyzed the spatial and temporal variation in wind energy in the East Asia and Western Pacific areas using IGRA site data, ERA5, and NCEP/NCAR reanalysis data from 2000 to 2021, and multi-variate empirical orthogonal function (MV-EOF) decomposition with the Pettitt mutation test, and the seasonal autoregression integrated moving average (SARIMA) model was used to predict the trend of wind speed. The spatial and temporal variations in wind energy in East Asia and Western Pacific areas were analyzed, and it was found that the richer wind-energy resources were mainly concentrated in the “Three Norths” (North China, Northwest China, and Northeast China) and Mongolia, followed by the Western Pacific areas. In addition, the T’ai-hang Mountains and the Qinghai-Tibet Plateau in China block the wind resources in the eastern and southern regions of East Asia, resulting in a shortage of wind resources in this region. In addition, the summer wind speed is significantly lower than in the other three seasons. The first-mode contributions of the MV-EOF wind field and geopotential heights, respectively, are 29.47% and 37.75%. The results show that: (1) There are significant seasonal differences in wind-energy resources in the study area, with the lowest wind speed in summer and the highest wind speed in winter. (2) The wind energy in the study area has significant regional characteristics. For example, China’s Qinghai-Tibet Plateau, Inner Mongolia, Xinjiang region, and Mongolia are rich in wind-energy resources. (3) Wind-energy resources in the study area have gradually increased since 2010, mainly due to changes in large-scale oceanic and atmospheric circulation patterns caused by global warming.

Published: September 2022

Tetracycline (TC) is a broad-spectrum antibiotic commonly, made use of in aquaculture and animal husbandry. After entering water bodies, it will represent a major threat to human health. In this study, sterculia foetida biochar (SFC) was readied by the combined hydrothermal pyrolysis (co-HTP) method with sterculia foetida as raw materials. Fen-SFC (Fe2-SFC, Fe3-SFC, and Fe4-SFC) was obtained by doping SFH with different concentrations of FeCl3. Finally, activation of peroxodisulfate (PDS) was achieved, using Fe3-SFC to degrade TC. The degradation of TC obeyed pseudo-second-order kinetics, and the constant of the reaction rate was 0.491 L mg−1 min−1. Radical trapping experiments, EPR test and electrochemical tests evidenced that the high catalytic performance of the Fe3-SFC/PDS system was ascribed to free radical pathway (•OH and SO4•−) and non-radical pathway (1O2 and electron transfer), in which the latter plays a dominant role. This research not only demonstrates a new kind of biochar as an effective catalyst for PS activation, but also offers an avenue for the value-added reuse of sterculia foetida.
A New Discrete Form of Hoek–Brown Criterion and Its Application to Limit Equilibrium Analysis of Rock Slope Stability
Authors: Lee Youn-Kyou , Pietruszczak S.
Published: September 2022

The generalized Hoek–Brown criterion (GHB) is recognized as one of the standard failure criteria in rock engineering and its validity extends to a wide range of rock mass quality. A drawback of this criterion is the difficulty of transforming it into an explicit form defining the Mohr failure envelope when its strength parameter a is not equal to 0.5. The information on the functional form of the Mohr envelope for the full range of rock mass conditions enables the implementation of classical engineering approaches, such as the limit equilibrium method and limit analysis, in the framework of the GHB criterion. Knowing that for a≠0.5 the exact closed-form representation of the Mohr envelope is not feasible, an alternative is to express it in an approximate analytical form. The main purpose of this study is to propose a new improved method to define an approximate Mohr envelope of the GHB criterion that is much more accurate compared with the recently published approximations. The idea behind the formulation is to expand the Balmer’s equation, which defines the relationship between the normal stress and minor principal stress at failure, by invoking the finite Taylor series centered at the known solution for a=0.5. The formulation is then completed by substituting this solution into another Balmer’s equation, defining the relationship between the shear strength and the minor principal stress. The Taylor polynomial approximations of up to third degree are considered in the formulation. The accuracy of the shear strength prediction is shown to be much better than that of the approximate formula of Lee and Pietruszczak proposed in 2021. An illustrative example of limit equilibrium analysis of rock slope stability, incorporating the new approximate expression for the Mohr envelope, is provided. The analysis incorporates a modified version of the Bishop approach, which is simpler and more rigorous than the original nonlinear expression. The study confirms that the new approximate representation of the Mohr failure envelope can facilitate the application of the GHB criterion to a range of practical rock engineering calculations.

Published: September 2022

The Qinghai–Tibet Plateau is one of the regions most strongly affected by climate change. The climate feedback of the distribution of plateau pika, a key species, is closely related to the trophic structure of the plateau ecosystem and the development of agriculture and animal husbandry on the plateau. In order to understand the impact of future climate change on the suitable distribution area of plateau pika, potential suitable distribution areas of Plateau pika were predicted using the MaxEnt model under three climate scenarios (SSP 1-2.6, SSP 2-4.5, and SSP 5-8.5) in the near term (2021–2040) and medium term (2041–2060). The predictions were found to be highly accurate with AUC values of 0.997 and 0.996 for the training and test sets. The main results are as follows: (1) The precipitation of the wettest month (BIO 16), mean diurnal range (BIO 2), slope, elevation, temperature seasonality (BIO 4), and annual mean temperature (BIO 1) were the main influencing factors. (2) In the historical period, the total suitable distribution area of Plateau pika in the Qinghai–Tibet Plateau accounted for 29.90% of the total area at approximately 74.74 × 104 km2, concentrated in the eastern and central areas of the Qinghai–Tibet Plateau. (3) The total suitable distribution area of pika exhibited an expansion trend under SSP 1-2.6 and SSP 2-4.5 in the near term (2021–2040), and the expansion area was concentrated in the eastern and central parts of the Qinghai–Tibet Plateau. The expansion area was the largest in Qinghai Province, followed by Sichuan Province and Tibet. In contrast, the suitable distribution area shrank in the Altun Mountains, Xinjiang. Under SSP 5-8.5 in the near term and all scenarios in the medium term (2041–2060), the suitable distribution area of Plateau pika decreased to different degrees. The shrinkage area was concentrated at the margin of the Qaidam Basin, central Tibet, and the Qilian Mountains in the east of Qinghai Province. (4) Plateau pika migrated toward the east or southeast on the Qinghai–Tibet Plateau under the three climate scenarios. Under most of the scenarios, the migration distance was longer in the medium term than in the near term.

The Sustainable Development Goals along with national policies pave the way to a sustainable, circular, and resource efficient development model. The environmental scenario could change with the promotion of biofuels such as bioethanol. Recent research on bioethanol aspires to reduce the costs production, via the optimization of process variables and the increase in ethanol yields. This study presented a stepwise upscaling of bioethanol production from dried source-separated municipal biowaste. Three different scales (250 mL, 4 L, 100 L) were examined applying advanced ethanol production via simultaneous saccharification and fermentation. The bioprocess runs at each of the three scales and produced very similar ethanol yields, indicating excellent scalability. The validated optimum conditions at the pilot scale were 25% solids loading, Spirizyme 40 μL/g starch, NS87014 175 μL/g cellulose, and 2% S. cerevisiae. The results from the pilot trials were very successful and repeatable. Τhe mean ethanol yield was 86.60 ± 4.91%, while the structural component such as starch and cellulose were efficiently hydrolysed. The produced ethanol was recovered and purified meeting the standards of absolute ethanol, rendering it suitable for industrial uses and for biofuel use as well. Energy consumption aspects were discussed as well. Conclusively, all the stages of the value chain for source-separated biowaste valorisation (collection, treatment, added value product recovery) were successfully showcased.

Published: September 2022

The eco-economic system is a complex system based on human activities, and the sustainability of the eco-economic system needs to maintain the balance between the three subsystems of society, economy, and environment. In this work, a comprehensive evaluation index system of the ecological-economic system of Liaoning Province in China was constructed by combining the emergy analysis and the system dynamic (SD) model, and four development scenarios were designed by adjusting the influencing factors of the ecological-economic system, based on the simulation and evaluation of the sustainable ecological and economic development of Liaoning Province from 2017 through to the next 19 years. The conclusion shows that, under the scenario of coordinated development type, the GDP, emergy density, and emergy output rate of Liaoning Province show an increasing trend; the ecological load, such as waste emergy ratio and environmental load rate, is small; and the sustainable development index and emergy sustainable development index are at a high level compared to other programs.
Ternary Metal-Alginate-Chitosan Composites for Controlled Uptake of Methyl Orange
Authors: Steiger Bernd G. K. , Wilson Lee D.
Published: September 2022

Three ternary metal composites (TMCs) with iron nitrate, aluminum nitrate, and copper nitrate (Fe-TMC-N, Al-TMC-N, Cu-TMC-N) were synthesized and their physicochemical properties were investigated. Characterization of the TMCs was achieved by elemental analysis (XPS), infrared (IR) spectroscopy and thermogravimetric analysis (TGA). The surface charge of the TMCs was estimated from the point-of-zero-charge (PZC), which depended on the type of metal nitrate precursor. The adsorption properties of the TMCs showed the vital role of the metal center, where methylene blue (MB) is a cationic dye probe that confirmed the effects of surface charge for effective methyl orange (MO) anion dye uptake. MB uptake was negligible for Al-TMC-N and Cu-TMC-N, whereas moderate MB uptake occurs for Fe-TMC-N (26 mg/g) at equilibrium. The adsorption capacity of MO adopted the Langmuir isotherm model, as follows: Al-TMC-N (422 mg/g), Cu-TMC-N (467 mg/g) and Fe-TMC-N (42 mg/g). The kinetic adsorption profiles followed the pseudo-second order model. Generally, iron incorporation within the TMC structure is less suitable for MO anion removal, whereas Cu- or Al-based materials show greater (10-fold) MO uptake over Fe-based TMCs. The dye uptake results herein provide new insight on adsorbent design for controlled adsorption of oxyanion species from water.

Published: September 2022

Relevance. The impact of obesity, as a multifactorial and multigenic disorder, on human health is a complicated multidisciplinary and simultaneously relevant problem in modern society. Inflammatory periodontal diseases are among the multiple consequences of obesity, with adverse effects on the quality and duration of life. Aim: To analyze the prevalence of inflammatory periodontal diseases in patients with metabolic syndrome according to the body mass index (BMI).

Material and Methods. We analyzed 306 records of patients with chronic inflammatory periodontal diseases. Patients’ weight and height were stated in the questionnaire attached to the dental patient record. The patients formed five groups based on their BMI.

Results. We found a high prevalence of periodontitis in groups with increased BMI and the progress of disease severity with the increase in BMI score.

Conclusion. The obtained results evidence a high prevalence of chronic generalized periodontitis in overweight and obese patients, which allows us to conclude that overweight and obesity are risk factors for periodontal inflammatory- destructive processes.

Authors: Eremin O. V. , Ostrovskaya L. Yu. , Zakharova N. B. , Kathanova L. S. , Kobzeva J. A. , Domenyuk D. A.
Published: September 2022

Relevance. Clinical and radiological assessment mainly forms the diagnosis of periodontal diseases. The diagnosis now requires speed, sensitivity and specificity since determining the patient's disease stage is fundamental to effective treatment. Crevicular fluid biomarkers can help monitor the current state of the disease, the effectiveness of treatment, and possibly predict the pathological process progression. The combination of various biomarkers will allow maximum objectivity in periodontal tissue condition assessment.

Materials and methods. The study examined 72 patients with inflammatory periodontal diseases and 25 periodontally healthy subjects. We performed a conventional clinical-instrumental examination and studied pro- and anti-inflammatory interleukins (IL-1β, IL-6, IL-17, TNF-α, VEGF, IL-8, MCP-1, IL-1RA) in the crevicular fluid. The obtained materials were processed using ROC analysis.

Results. Inflammatory periodontal diseases demonstrate an increase in pro-inflammatory cytokines / chemokines (IL-1β, TNF-α, IL-6, IL-17, IL-8, MCP-1) and vascular endothelial growth factor (VEGF) in the crevicular fluid, a decrease in the anti-inflammatory cytokine, IL-1RA. The levels of pro- and anti-inflammatory cytokines, cytokines/ chemokines, VEGF are associated with the periodontal destruction severity caused by inflammation. The accumulation of VEGF, IL-6, and IL-1β in the crevicular fluid predicts the clinical course of gingivitis, VEGF, TNF-α, IL-6, IL-1β – mild and moderate periodontitis.

Conclusion. The present study allows us to confirm the diagnostic value of methods for obtaining and quantifying a group of immunoregulatory cytokines in the crevicular fluid as predictors and parameters of the disease progression and the development of osteodestructive changes in the periodontium.

Published: September 2022

Relevance. If a foreign body is present in a maxillary sinus, it should be surgically removed. Endoscopic and radical surgery are the main methods. Clinician’s subjective feelings determine the surgical access, which can cause complications. Therefore, the search for new methods of planning and visualizing the operation stages remains relevant.

Materials and methods. Before the operation, the patient had a cone-beam computed tomography in a marker holder frame. The 3D slicer program allowed the segmentation of the foreign body and surrounding anatomical features. A marker, fixed on the patient's head, allowed transmitting information to the augmented reality glasses during the operation.

Results. The surgery was performed under local anesthesia in an outpatient facility. The diameter of the antrotomy hole was 5 mm. No postoperative complications were recorded.

Conclusion. The proposed technique provides significant visual control and minimal trauma to the sinus during surgery.

Authors: Kirakosyan L. G. , Varukha A. P. , Antonik P. M. , Arutyunov S. D. , Timoshchenko M. V.
Published: September 2022

Relevance. An analogous recording of occlusal relationships (articulating paper, foil, etc.) is not sufficiently informative for precise determination of occlusal forces and sequence, which is related to the large inaccuracy, labour intensity and lower predictability of prosthetic treatment results. Aim. The study aimed to evaluate the effectiveness of fixed polymer prototype dental bridges in patients with tooth-bounded edentulous spaces and occlusal defects.

Material and Methods. The randomized controlled study comprised two study groups: control (n = 21) and main (n = 21), which included the patients with tooth-bounded posterior missing teeth (second premolar and first molar). Prosthetic treatment corresponded to the conventional protocol in the control group. The main group had the missing teeth replaced with prototype prostheses and analogous-digital analysis of occlusal relationships. Intergroup effectiveness comparison rested on the integral occlusal score (IOS) data that considered scores received with T-scan 3 system (TekScan, USA). We also performed an intragroup comparative analysis of the periodontium condition around the abutment teeth using the Doppler ultrasound integral score (DUIS) at the stages before and after the treatment.

Results. The study did not reveal statistically significant differences between the values of IOS in the control and main study groups before the treatment (p > 0.05). At the followed treatment stages, control group IOS values significantly differed from those of the main group, namely, by 65.35 % (p < 0.05) just before the replacement of the provisional bridge by the final prosthesis; by 76.19 % (p < 0.05) immediately after the final prosthesis delivery; and by 65.94 % (p < 0.05) one week after the delivery of the final prosthesis. The Doppler ultrasound integral score values reflected the statistically significant positive changes in the study groups (p < 0.05).

Conclusion. Fixed polymer prototype prosthesis placement in patients with posterior tooth-bounded edentulous spaces and occlusal defects allowed us to increase prosthetic treatment effectiveness, improve microcirculation around abutment teeth, and harmonize the occlusion, decreasing the risk of possible damage to a ceramic bridge.
Stratigraphy of the Coal-Bearing Blackhawk Formation on North Horn Mountain, Wasatch Plateau, Utah
Authors: Johnson Jan L.
Published: September 2022

Coal- bearing rocks of the Cretaceous Blackhawk Formation crop out along the eastern margin of the Wasatch Plateau in central Utah. On North Horn Mountain the Blackhawk Formation ranges from 215 to 290 meters in thickness and consists of interbedded sandstone, shale, siltstone, carbonaceous shale, coal, and limestone. The lower half of the formation, which contains the economically important coal beds, was deposited predominantly in a shallow water , wave-modified delta system. The upper half of the unit was deposited in fluvial environments of meandering streams and floodplains. The source for the clastic sediments of the Blackhawk Formation was to the west. Potentially minable coal exists in the Hiawatha and Blind Canyon beds and possibly in the Bear Canyon bed. The thickest beds were measured in the southeastern part of the study area, with 5.3 meters of the Blind Canyon bed found in one measured section. These coals are high quality and have lateral continuity, but the thickness varies and scattered wants and splits are to be found. Coal reserves on North Horn Mountain are large and should become an important source of supply for local and regional markets.

Published: September 2022

Сердечно-сосудистые заболевания остаются ведущей причиной заболеваемости и смертности во всем мире и в системе здравоохранения обуславливают самую высокую долю затрат. Патоморфологической основой ишемической болезни сердца в подавляющем большинстве клинических ситуаций является атеросклероз коронарных артерий. В последнее время множество исследований посвящено изучению ранней стадии атеросклероза – субклинического атеросклероза. Дестабилизация гемодинамически незначимых, бессимптомных атеросклеротических бляшек может привести к развитию инфаркта миокарда. В статье обсуждается распространенность, клиническая значимость необструктивного атеросклероза коронарных артерий. Отдельное внимание уделено шкалам стратификации сердечно-сосудистого риска. Обозначены современные методы диагностики коронарного атеросклероза, методы визуализации «нестабильных» атеросклеротических бляшек. В реальной клинической практике оценить «нестабильность» атеросклеротической бляшки не представляется возможным, поэтому сам факт наличия субклинического атеросклероза коронарных артерий позволяет отнести пациента к категории высокого и очень высокого риска.

Cardiovascular diseases remain the leading cause of mortality and morbidity worldwide and represent the highest proportion of costs in healthcare systems. In the vast majority of cases, the pathomorphological basis of coronary heart disease is coronary artery atherosclerosis. Many of the recent research have been devoted to the study of the early stage of atherosclerosis – subclinical atherosclerosis. Destabilization of hemodynamically insignificant, asymptomatic atherosclerotic plaques can lead to the development of myocardial infarction. The article discusses the prevalence and clinical significance of non- obstructive atherosclerosis of the coronary arteries. Special attention is devoted to the scales of cardiovascular risk stratification. Modern methods of coronary atherosclerosis diagnosis, methods of visualization of unstable atherosclerotic plaques are outlined. Considering that it is impossible to assess the instability of atherosclerotic plaque in real clinical practice, the presence of subclinical coronary atherosclerosis itself allows the patient to be classified as high and very high risk.
Supraventricular Tachycardia in Childhood: Classification, Diagnosis, Treatment
Authors: Строгий В.В.
Published: September 2022

Наиболее распространенным видом нарушений ритма сердца у детей являются наджелудочковые тахиаритмии, составляющие в структуре до 95% от всех тахикардий у детей. Несмотря на почти столетнюю историю исследования различных тахиаритмий остается неизученным ряд вопросов: их распространенность, своевременная диагностика скрытых и латентных форм, определение сроков и показаний к проведению хирургического лечения, а также эффективности различных методов лечения. Данные проблемы обусловлены врожденными особенностями состояния проводящей системы сердца, которые в одних случаях могут способствовать бессимптомному течению или только наличию электрокардиографических признаков аритмии, а в других – сопровождаться выраженными признаками вегетативной дисфункции, нарушениями гемодинамики и повышать риск внезапной сердечной смерти. Нередко бессимптомное начало у детей, отсутствие гемодинамических проявлений приводят к запоздалой диагностике и несвоевременному лечению, что способствует более быстрому развитию аритмогенной кардиомиопатии, увеличению числа сложных аритмий перманентного характера (фибрилляция, трепетание предсердий), развитию сердечной недостаточности. Таким образом, актуальность данной проблемы обусловлена вопросами ранней диагностики, выбора сроков и методики лечения.

The most common type of cardiac arrhythmias in children are supraventricular tachyarrhythmias, which account for up to 95% of all tachycardias in children. Despite almost a century of research on various tachyarrhythmias, a number of issues remain unexplored: their prevalence, timely diagnosis of latent and latent forms, timing and indications for surgical treatment, as well as the effectiveness of various treatment methods. These problems are caused by congenital features of the state of the conduction system of the heart, which in some cases can contribute to an asymptomatic course or only the presence of electrocardiographic signs of arrhythmia, and in others they can be accompanied by pronounced signs of autonomic dysfunction, hemodynamic disorders and increase the risk of sudden cardiac death. Often asymptomatic onset in children, the absence of hemodynamic manifestations lead to delayed diagnosis and untimely treatment, which contributes to the more rapid development of arrhythmogenic cardiomyopathy, an increase in the number of complex arrhythmias of a permanent nature (fibrillation, atrial flutter), and the development of heart failure. Thus, the relevance of this problem is due to the issues of early diagnosis, the choice of terms and methods of treatment.

Background: Lumbar puncture (LP) is a bedside procedure used to investigate diseases of the central and peripheral nervous systems. We report the experience of a major teaching hospital in this procedure over a 5-year period. Methods: Medical records were reviewed of patients aged ≥ 13 years who underwent LP in the years 2014¬–2018. Age, gender, technique, indications, findings, complications, and final diagnosis were analyzed. Results: 195 patients, of whom 133 (68.2%) were females (aged 40.0 ±15.7) were studied. Opening pressure was measured in 104 (53.3%) patients (86, 82.7% females) showing a mean of 31.2±12.1cm, and closing pressure was measured in 54 (27.7%) patients with a mean of 16.5±5.7cm. Leukocyte and erythrocyte counts, and glucose and protein levels were measured in most patients (99.0%, 98.5%, 96.9%, and 96.9%, respectively). Bacterial culture and gram stain were performed in 28 (14.4%) and six (3.1%) patients, respectively. Cytology and oligoclonal bands were studied in 16 (8%) and 28 (14.4%) patients, respectively. Headache, peripheral neuropathy, and papilledema were the main indications found in 69 (35.4%), 41 (21.0%), and 26 (13.3%) patients, respectively. The most common final diagnoses were idiopathic intracranial hypertension, central nervous system inflammatory diseases, peripheral neuropathy, and meningoencephalitis in 68 (34.9%), 27 (13.3%), 20 (10.3%) and 16 (8.7%) patients, respectively. No major complications were recorded. Conclusions: LP is a common bedside procedure and the most common indications were intracranial pressure and inflammatory neurological disorders. It is a quite safe and useful procedure.

Background: The postpartum period is critical for women due to significant bio-psychosocial changes and the consequences of delivery.

Aims: The purpose of this study was to investigate the role of the use of contraceptives and other health-related factors in the risk of developing postpartum depression among women in Jordan.

Materials and methods: A cross-sectional, descriptive-correlational design was used to recruit 803 women using a convenience sample technique from the central district of Jordan. Data were collected on depressive symptoms, contraceptive use and type, and pregnancy health-related factors. 

Results: Using binary logistic regression analysis, non-hormonal contraceptives and musculoskeletal pain were significant predictors (p<.05) of the risk of developing depressive symptoms in the sampled women (OR=4.1, 3.8; respectively). For the women in our sample, 24.9% (n=200) developed depressive symptoms. Most of those who felt depressed reported suffering from insomnia (50.0%] and baby blues (13.0%), while loss of appetite was reported by 33.0%. The analysis also showed that 51.0% (n=409) had used at least one method of contraception. Among those using contraceptive methods, 31.0% had only used hormonal contraceptives compared to 69.0% using non-hormonal forms.

Conclusion: Non-hormonal contraceptive use and musculoskeletal pain were found to be significantly associated with the risk of developing postpartum depressive symptoms. Family and reproductive health professionals need to emphasize the bio-psychological aspects of health for pregnant and postpartum women.
INTERNATIONAL EXPERIENCE FOR WAR-TIME MONETARY POLICY: LESSONS FOR UKRAINE
Authors: SHAROV Oleksandr
Published: September 2022

Monetary policy directly acts as a significant element of national security. Rather than merely influencing economic security, it is relevant in broader terms as its results indirectly affect the social, ecological and other aspects of societal existence. The paper considers the examples of monetary policy implemented in war-time of different eras based on the existing system of monetary management (Bretton Woods, post-Bretton Woods, inflation targeting, floating exchange rate, etc.). Focus is placed on the changing principles of monetary policy during the war waged by Russia against Ukraine. On the one hand, Russia’s monetary policy has returned to the administrative practices of the USSR and has practically suspended conversion of the ruble. On the other hand, Ukraine has employed limited administrative restrictions as the National Bank of Ukraine tries to uphold the main principles of market economy. The author concludes that despite the reoccurrence of some key approaches, in general, the international experience indicates the absence of any particular standards of war-time monetary policy. Therefore, evidently in such conditions it is more reasonable to develop an individual approach to monetary policy that takes into account the experience of other countries in one way or another.
Interfacial effects on sensitization of chemically amplified extreme ultraviolet resists
Authors: Kozawa Takahiro
Published: September 2022

With the improvement of lithography resolution in the horizontal direction, the thickness of resist films becomes thin to avoid pattern collapse. The thinning of resist films is an important issue in the development of the next-generation lithography process. In this study, the interfacial effects on the sensitization of chemically amplified extreme ultraviolet (EUV) resists were investigated using a Monte Carlo method on the basis of their sensitization mechanism. The chemically amplified resist is a standard resist used for the fabrication of semiconductor devices. In chemically amplified resists, thermalized electrons reduce sensitizer molecules upon exposure to EUV radiation. The low-energy secondary electron dynamics at the vacuum-resist and resist-underlayer interfaces strongly affected the distribution of decomposed sensitizers. In particular, the resist bulk layer almost disappeared at 20 nm pitch in the specific cases. The control of interfaces becomes important in the development of the next-generation lithography process.

Drug abuse is the use of drugs in amounts or by methods that is harmful for the health. Drug use disorders (DUD) are associated with a range of adverse health outcomes including increased mortality rates [1, 2]. For example, patients in opioid substitution treatment (OST) are shown to have significantly higher non-drug-related mortality including Cancer than the general population [3, 4]. According to the American Cancer Society, substance abuse and addiction make up about 30% of all cancer deaths. In this review article we tried to summarize that drug abuse disorders are risk factors for Cancers.
COVID-19 and the Shut Down of Courts in Nigeria; Any Hope for the Awaiting Trial Detainees?
Authors: James Mrs. S. T.
Published: September 2022

The outrageous number of Awaiting Trial Inmates is one of the know fallouts of the weak criminal justice system of Nigeria. This phenomenon was egregiously exposed during the Covid-19 Pandemic. In the face of the lockdown and consequent shut down of courts, the fate of these inmates is largely uncertain. This article considers the fairness of this treatment by considering the pre-trial rights of defendants under the Nigerian Constitution. It recommends the issuance of Bondsmen Regulation to ease the process of perfecting bail in Nigeria. The article concludes by advocating for a complete over haul of the Nigerian Bail System.
