Objective We aimed to explore whether nursing professionals’ psychological states affect their grief response for a patient’s death in the coronavirus disease-2019 (COVID-19) inpatients’ ward.Methods Survey was conducted among frontline nursing professionals working in COVID-19 inpatients wards at three tertiary-level affiliated hospitals of the University of Ulsan during April 7–26, 2022. Participants’ information such as age, years of employment, or marital status were collected, and their responses to rating scales including Pandemic Grief Scale (PGS) for healthcare workers, Stress and Anxiety to Viral Epidemics-9 items (SAVE-9), Patient Health Questionnaire-9 (PHQ-9), Loneliness and Social Isolation Scale, and Insomnia Severity Scale (ISI) were collected.Results All 251 responses were analyzed. We observed that 34% reportedly suffered from depression. The linear regression analysis showed that a high PGS score was expected by high SAVE-9 (β=0.12, p=0.040), high PHQ-9 (β=0.25, p<0.001), high loneliness (β=0.17, p=0.006), and high ISI score (β=0.16, p=0.006, F=20.05, p<0.001). The mediation analysis showed that the depression of nursing professionals directly influenced their pandemic grief reaction, and their work-related stress and viral anxiety, insomnia severity, and loneliness partially mediated the association.Conclusion We confirm that frontline nursing professionals’ depression directly influenced their grief reaction, and their work-related stress and viral anxiety, insomnia severity, and loneliness partially mediated the association. We hope to establish a psychological and social support system for the mental health of nurses working in the COVID-19 wards.

Published: April 2023

The subject of the study is the study of models and methods for short-term forecasting of energy consumption in power systems based on recurrent analysis of time series. The aim of the work is a recurrent analysis of the time series of energy consumption of a metallurgical enterprise and the development of a program in the Matlab environment for automating calculations and experimental testing of data available for research in PJSC Electrometallurgical Plant "Dniprospetsstal" named after A. M. Kuzmin. The following tasks have been solved: the methodology for constructing recurrent diagrams and their quantitative analysis have been considered; a model of the time series and the phase trajectory of the time series was built to visualize the change in energy consumption during the day; software for constructing recurrent diagrams in the Matlab package was developed. Methods were used: analysis of time series based on recursive analysis to study the characteristics of the state of the system on the example of a metallurgical enterprise. The results were obtained: software was developed in the Matlab environment for short-term forecasting of energy consumption in power systems, and quantitative indicators were calculated that can be used to characterize the state of the system and analyze energy consumption in the summer and winter seasons. Conclusions: in the course of the study, software for constructing and quantitative analysis of recurrence diagrams in the Matlab package was developed, with the help of which patterns were discovered and information about the properties of the system under study was obtained. Based on the analysis of the average values of quantitative measures in the off-season for 2018–2021, it can be seen that the summer period is characterized by greater predictability, as well as a significantly higher latency indicator, which characterizes the average time when the system can spend in a more or less unchanged state. Confirmed on real data, the benefits of using the recursive analysis method for estimating electricity consumption, as well as more efficient modeling of this process, can lead to an increase in the accuracy of forecasting its future dynamics.

Published: April 2023

Subject of the study: the process of acoustic information protection in computer systems of critical applications to ensure the required level of system security. The aim of the article is to analyze the methods of acoustic information protection in computer systems of critical application by means of masking to ensure the impossibility of unauthorized access to the system. The article solves the following tasks: to analyze the software and hardware masking of speech; to study the masking of speech messages in order to introduce unrecognizability; to study the features of speech message compression; to investigate methods of covert transmission of acoustic information. The results of the work, which were obtained using mathematical methods of information transformation in computer systems, are potentially possible methods of masking speech messages to ensure the impossibility of unauthorized access to the system. The analysis of the functioning of the presented methods has led to the following conclusions. One of the perspective directions of acoustic information protection in communication channels and dedicated premises can be considered the creation and development of computerized speech masking systems along with or in conjunction with traditional technologies of semantic protection of acoustic information, namely, speech signal classification based on cryptographic algorithms. The main requirements for today's systems that provide protection of acoustic information in critical computer systems are speed and efficiency of various speech signal processing procedures using standard inexpensive technical means of computer telephony, namely: a personal computer, sound card, telephone line interface device and/or modem. These requirements can be met by applying digital methods of dynamic spectral analysis, i.e. synthesis of speech and audio signals. The choice of specific methods and means of speech masking as one of the types of semantic protection of acoustic information will depend on the practical requirements for the speech protection system and the technical characteristics of the acoustic information transmission channel. Further research is desirable to analyze the possible use of methods for synthesizing large ensembles of quasi-orthogonal discrete signals with improved ensemble, structural and correlation properties to ensure higher security indicators of acoustic channels in computer systems of critical applications.

Published: April 2023

Problem statement. The task of assessing the level of atmospheric air radioactive contamination in the case of an extreme situation on the territory of the Zaporizhzhya NPP, which leads to an instantaneous radioactive aerosol emission, is considered. An analysis of the dynamics for the zones’ formation of radioactive contamination in the wind direction towards Nikopol is conducted. For the prompt solution of this of this forecast issue, the creation of a multifactorial numerical model is required, which allows for prompt analysis of the size and intensity of radioactive contamination areas. The purpose of the article. Creation of a numerical model and computer code for the operational analysis of radioactive contamination areas formed during the instantaneous release of radioactive pollutants into the atmosphere. Methodology. The computer code is based on a numerical model, which is a differential analogue of the multifactor kinematic equation of mass transfer of a radioactive impurity in atmospheric air. The mass transfer equation takes into account the wind speed field, atmospheric turbulent diffusion, and the intensity of radioactive substances emission into the air. For the numerical integration of the mass transfer equation, the splitting method is used followed by the use of finite-difference schemes. Determination of the volumetric activity value at each splitting step is implemented by an explicit formula. Scientific novelty. An effective numerical model was developed and its software implementation was conducted for operational analysis of the formation of radioactive contamination areas in the atmosphere during an extreme situation at a nuclear power plant, accompanied by the emission of radioactive substances. The model takes into account a complex of factors that affect the process of radioactive impurities spread in the atmosphere. Practical value. A computer code was developed for calculating the dynamics of the formation of radioactive contamination zones in the atmosphere based on the developed numerical model. This makes it possible to analyze the consequences of emergency emissions on the territory of the NPP using the computational experiment method. Conclusions. A mathematical model was developed for the operational analysis of radioactive contamination level of the atmospheric air due to an extreme situation at the nuclear power plant, which leads to an intense instantaneous release of radioactive substances. The results of a computational experiment based on the developed numerical model are presented.

Published: April 2023

Problem statement. High stability composite materials, such as polymer concrete, play a significant role in modern practice. Due to a continuing demand for the use of building materials resistant to aggressive environments both in Ukraine and globally, as well as their prospective use in construction, metallurgy, and chemical industry, the investigation deals with deformations of polymer concrete in various types of environment at high temperature. The purpose of the research is to find mechanisms to increase the stability of polymer concrete in aggressive environment. The object of the study is polymer concrete based on modified furan resins. The subject of the study is deformation characteristics (namely creep) of polymer concrete in different environments (water, sulfuric acid) at different temperatures. Results. In the course of research of the deformation parameters of polymer concrete in various environments were identified. Conclusions. The deformation parameters of polymer concrete on modified furan resins in hot sulfuric acid solutions were determined. It has been proved that the decrease in strength and deformation properties also depends on the hygroscopicity of benzosulfonic acid. It is shown that under simultaneous influence of aggressive environment and temperature in a stressed state the phenomenon of creep is more intensive and the polymer concrete is destroyed in a short time.

Authors:   Korean Association for Qualitative Inquiry, Kim Nakyung , Lim Nayoung
Published: April 2023

This study aimed to explore the experiences of art therapists working with child and adolescent clients who have experienced complex trauma. To achieve this goal, seven art therapists with at within the last three years of experience treating over 10 clients with complex trauma within the last three years were interviewed using a consensual qualitative research methodology. The resulting analysis revealed 5 domain 18 categories: “the moment of meeting the client,” “the therapist’s role after the meeting,” “various aspects of artwork,” “challenges faced in the field,” and “motivations for overcoming difficulties.” The art therapists experienced the therapeutic coexistence of physical and emotional resonance with their clients during the treatment process, and their professional role involved building a trustworthy therapeutic relationship by securing the client’s sense of safety through recognition and acceptance. Personal experiences of psychological burnout and vicarious trauma were also encountered, but they experienced the healing power of art, a sense of relief, and other therapeutic effects through the client’s artwork during the art therapy process. When experiencing various difficulties during the treatment process, the art therapists overcame feelings of powerlessness and frustration by using techniques such as super-vision and peer-vision to evolve and develop as professional art therapists. The results of this study provide concrete examples of the therapeutic attitudes necessary for art therapists treating children and adolescents with complex trauma, and provide information on the therapeutic factors necessary for coping with trauma, thereby contributing to the improvement of the professionalism of art therapists.
THE EXPERIMENTAL OF IMPACT OF ADDITIONAL MAGNETIC FIELDS AND NITROGEN PRESSURE ON OLIVE OIL DROPLET COMBUSTION
Authors: Perdana Dony
Published: April 2023

This experiment studies the impact of a magnetic field of attraction and various nitrogen pressures in the combustion chamber on the characteristics of the flame. To replace depleted fossil fuels, the usage of vegetable oil is crucial. This research aims to probe the droplet combustion of olive oil on evolution, temperature, height, and ignition delay. The camera's high speed is 120 frames per second front-facing camera records the process from the start flamed until it has extinguished. A droplet of olive oil is placed on a type K thermocouple between two magnet rods in a nitrogen-pressurized chamber—three variations of nitrogen pressure in the combustion chamber, which included 0.5, 1, and 1.5 bar. The results found that the nitrogen pressure of 0.5 bar led to evolution, and the flame stability was more stable. Moreover, the highest temperature and flame delay was shorter than the pressures of 1 bar and 1.5 bar. At a pressure of 0.5 bar, the flame evolution was 1200 milliseconds, the maximum temperature was 741 °C, and the ignition delay of 4506 milliseconds was shorter than the other two pressures. That occurred due to high nitrogen pressure inhibiting the collision reaction of the olive oil fuel vapor with air. Meanwhile, adding an attraction magnetic field can centralize oxygen and fuel molecules in the area of the reaction zone, resulting in rapid combustion and a shorter flame delay change.
The Opening of the Monument to Grand Duke Nikolai Nikolaevich in 1914 and One of the Last Bulgarian Attempts to Return Russian Sympathies
Authors:   Institute of Slavic Studies, Russian Academy of Sciences, Gusev Nikita
Published: April 2023

This article considers the attempt of the Bulgarian envoy in St. Petersburg, R. Dimitriev, to improve the attitude of Russian society to Bulgaria. The occasion was the unveiling of a monument dedicated to Grand Duke Nikolai Nikolaevich the Elder, who commanded the Russian army in the Russo-Turkish War of 1877–1878. The monument depicted flag bearers modelled on real individuals. R. Dimitriev proposed to send a Bulgarian flag bearer, and with him a delegation of representatives of the country. However, the Serbs, Romanians, and Montenegrins did the same. Nicholas II granted an audience to all the Balkan delegations and all the participants of the delegations were awarded Russian orders. In his report to Sofi a, R. Dimitriev presented everything in a winning tone and reported that the foundations had been laid to combat Serbian and Greek propaganda in Russia. However, the order of the ceremonies assigned Bulgaria a place after Romania and Serbia, which clearly indicated Russian priorities and put an end to attempts to raise the issue of revising the Bucharest Treaty of 1913. In addition, in the public space, the celebrations in connection with the unveiling of the monument were replaced by the celebration of the birth of Prince of the Imperial Blood Vsevolod Ioannovich, whose baptism was attended by his uncle, Serbian heir to the throne Alexander, as well as Prime Minister N. Pašić. World War I, which soon followed, finally ended the possibility of changing the Russian image of Bulgaria for the better, and the revolution of 1917 led to the demolition of the monument to Nikolai Nikolaevich.
Funeral and Memorial Rites of Pontic Greeks of Sochi (Based on Field Materials of 2022)
Authors:   Lomonosov Moscow State University, Klimova Ksenia , Nikitina Inna ,   European University at St. Petersburg
Published: April 2023

This article analyses the material collected during an ethnolinguistic expedition to the Pontic Greeks of Sochi, which took place from the 15th to 25th of July, 2022. In the settlements of Krasnaya Polyana, Lazarevskoye, Adler, Sochi (center), Lesnoye, and Galitsino, the Pontic dialect of the Greek language and the characteristic elements of traditional Pontic culture are preserved to this day. The Greek population arrived in this region in the second half of the nineteenth century. The first settlers fled from the Ottoman Empire to Russia and historical memory of these events is still preserved. The Pontic funeral and memorial rites are structurally similar to the East Slavic and Greek ones. Some Pontic death-related lexemes are similar to Greek, while others differ (for example, the Pontic verb monázo ‘to keep vigil over a dead body’). A number of ritual elements (such as throwing flowers behind a funeral procession or distributing gifts at a funeral) were borrowed by the Pontians from their Eastern Slavic neighbours. Of particular interest is the use of objects associated with the deceased in magical rituals. One Pontic funeral tradition is the special way of decorating the funeral dish (kukía). The article also describes the changes in funeral rituals during the Soviet era, such as the increased role of ritual specialists and the custom of reading the Psalms for the deceased at home.
Features of Teaching Paronyms to Greek Students Studying Bulgarian and Russian
Authors:   National and Kapodistrian University of Athens, Yusupova Kamilla
Published: April 2023

The article is devoted to the topical issue of perception and compatibility of paronymic pairs among Greek students. In Greece, there are three departments of Slavic studies: the Department of Russian Language and Literature and Slavic Studies at the National and Kapodistrian University of the Athens, the Department of Languages, Literature and Culture of the Black Sea Countries of the Demokritus University of Thrace in Komotini and at the Department of Balkan Studies, Slavic and Oriental Studies of the University of Macedonia in Thessaloniki. Students study Russian, Bulgarian and other Slavic languages as foreign languages at these universities. Among the incoming students there are: Greeks (who do not know any Slavic language), who speak one of the Slavic languages (graduated from schools or other educational institutions in their countries) and bilinguals (who arrived or were born in Greece). The purpose of the study programs at these faculties is not only to teach students Russian as a foreign language, but also to give them a complete philological education. Despite the fact that there are quite a few dictionaries of paronyms, there is a lack of educational dictionaries, manuals and electronic resources in the Bulgarian and Russian languages for a foreign audience. Students have difficulties due to misunderstanding, the use of paronyms both in oral and written speech of the Russian and Bulgarian languages at advanced levels. Examples of paronyms with close-sounding semantic correspondences and differences in Russian, Bulgarian and Greek are given. When teaching a foreign language, one should take into account the linguistic and cultural characteristics of not only the native language of students, but also their knowledge of other languages in order to avoid interference. At the end of the article, methodological recommendations are given in the teaching of paronyms.

Published: April 2023

This year, young scientists from Moscow, St. Petersburg, Smolensk, and Regensburg (Germany) took part in the Linguistics section of the conference. The reports were divided into three thematic blocks. The first block was devoted to the connection between the past and the present in modern Slavic languages. The reports touched upon the issues of lexicology, morphology, and syntax of the Russian language in comparison with other Slavic languages, the results of corpus studies of the grammar of modern Slavic languages, and special attention was paid to sociolinguistic research in Slavic national minorities. During the second session of the “Linguistics” section, topical problems of ethnolinguistics were discussed. The vast geography of the research conducted by young scientists involved in the study of traditional culture included the Saratov region of Russia, Serbia, Macedonia, and China. The third thematic block of reports was devoted to studies of printed and handwritten monuments of Slavic writing, as well as texts in modern Slavic languages. Reports were presented in which the glosses in the monuments of the 17th century were analysed, a classification of ancient Russian toponyms was proposed, and the linguistic means of expressing the national idea in a Polish play of the early 20th century were studied. The moderators of the subsections were employees of the Institute of Slavic Studies of the Russian Academy of Sciences, who are experts in each of the designated topics. Scientific communication took place between young scientists, and many presentations were accompanied by lengthy discussions, in which not only the speakers themselves, but also their senior colleagues participated. Some of the speakers take part in the conference every year, while others presented the results of their research within the walls of the Institute for the first time, which indicates the relevance of this conference.

Individual Differences in Emotion Regulation: Personal Tendency in Strategy Selection Is Related to Implementation Capacity and Well-Being
Authors: Rammensee Rebecca Anik , Morawetz Carmen , Basten Ulrike
Published: April 2023

Individual differences in emotion regulation (ER) are assumed to play an important role in resilience and mental health. In a standardised laboratory setting, we investigated how the individual tendency to select specific ER strategies (reappraisal vs. distraction) and the capacity to implement these strategies are related (a) to each other and (b) to trait markers of mental health in a non-clinical sample. For 159 participants, individual regulatory tendency and capacity were assessed with established experimental tasks focusing on ER selection and implementation, respectively. Trait markers of mental health were assessed with questionnaires on emotion regulation habits, trait resilience, and well-being. We observed that ER tendency and capacity were positively correlated specifically for the condition in which participants were facing negative stimuli of high intensity. Furthermore, while ER capacity was not consistently associated with trait markers of mental health, a higher tendency to choose reappraisal (as opposed to distraction) was associated with higher trait resilience and better well-being. This study is the first to provide experimental evidence that a person’s tendency to select a particular ER strategy is associated with the person’s capacity to implement it successfully. Moreover, based on experimental data, it confirms an association between reappraisal tendency and mental health that has previously been suggested by questionnaire studies. This points to regulatory selection as a potential target for interventions fostering resilience and mental health. In a next step, intervention studies should clarify whether the association reflects a causal influence of regulation tendency on resilience.

Mammals of Yakutia: Changes in the understanding of the composition of the mammal fauna over the past 50 years and an Annotated List. Part 2. Carnivorous, Cetaceans, and Artiodactyls
Authors: Volpert Ya. L. , Shadrina E. G. , Okhlopko I. M.
Published: April 2023

This study presents data on the mammal fauna including Carnivora (5 families, 12 genera, and 17 species), Cetacea (2 families, 3 genera, and 3 species), and Artiodactyla (3 families, 8 genera, and 3 species). A total number of 28 species demonstarted an increase in the richness of these taxa over the past 50 years due to the introduction of one carnivorous species and two ungulate species. Among the latter, only the introduction of musk ox can be considered successful. In addition, sporadic occurrences of four species that were not part of the original fauna in Yakutia have been registered. The northern sea lion and bowhead whale can colonize marine regions of Yakutia, whereas the Asian badger can colonize its terrestrial regions if the current climate trend stays unchanged. The tiger is unlikely to survive the Yakutian conditions, due to both low temperatures and low density of the ungulates, which constitute the major part of its food supply. At present, the complete list of species that inhabit the terrestrial and marine areas of Yakutia includes 70 representatives of the Mammalia class. The major part of the mammalian fauna of the region consists of indigenous species, whereas the share of non-native species was only approximately 10%. The changes in the composition of the mammalian fauna over the last 50 years are connected with a better current knowledge of the regional fauna, introduction, and changes in the taxonomic rank of species and subspecies. Moreover, four new species were identified: Chiroptera (2), Insectivora (1), and Rodentia (1). Some clarifications have been made to the taxonomic rank of species and subspecies belonging to the genera Ochotona, Urocitellus, and Alexandromys (Microtus). The use of genetic approach can clarify the taxonomic rank of a number of species. More complete and precise data on the composition of the faunistic list, geographic ranges of these species can be obtained by covering the territorial gaps in the previous studies and additional research on understudied taxa, in particular chiropterans and marine mammals.

Published: April 2023

A unique project on the hybridization of domestic sheep with wild bighorn sheep of the Yakut subspecies (Ovis nivicola lydekkeri) was implemented under extreme conditions in Yakutia. Hybridization was performed to obtain new forms that combine productive indicators with specific adaptation qualities to harsh breeding conditions. Viable hybrids of both sexes were obtained via laparotomy during the artificial insemination of domestic sheep with frozenthawed epididymal male bighorn sheep. We compared the hybrids with domestic lambs. At birth, the hybrids had a live weight of 2.65±0.19 kg, which is 29 % less than that of domestic lambs. A difference in live weight was noted before reaching the age of 20–24 months; however, by 36 months, hybrid males outnumbered domestic rams of the same age. We found that in the early postnatal period, hybrids were satisfied with their mothers’ milk faster and more often, and their daytime sleep was short and shallow. The hybrids also showed a high degree of curiosity, jumping ability, caution, and clear imitation of the mothers’ behavior. In terms of growth and development, the hybrids were tall and narrow-bodied because of their high mobile activity, as well as differences in nutrition. The hybrid offspring differed in chromosome set from the parental forms, having a diploid set equal to 2n = 53, whereas the maternal form of the sheep had 2n = 54, and the paternal form had 2n = 52. The resulting hybrids are fertile, and differ from their peers in the dynamics of development, nutrition, and ethology. They have phenotypic features similar to those of the paternal form, and a new improved form of the genotype is the basis for selection in sheep breeding.

This article provides data on the identification and distribution of Au-Ag minerals in the tailing dump of the processed ores in the pyrite-polymetallic deposit within the Salair ore field (Talmovskiye Sands, Salair). The mineral and chemical compositions of the samples were studied using atomic absorption, mass spectrometry with inductively coupled plasma, X-ray diffractometry, and scanning electron microscopy. We have established that a horizon of secondary enrichment was formed (with Au and Ag contents up to 5,3 and 53.7 g/t, respectively) over a long period of the tailing dump existence (more than 90 years) and at a depth of 0,6-0,8 meters. Gold and silver are unevenly distributed along the section and are present in three species:1) native (Aus, Ags), 2) mineral (acantite, petrovskaite), and 3) isomorphic (sulfides and secondary films). The identified residual and newly formed gold-silver minerals indicate active supergene processes of Au-Ag dissolution, migration, and precipitation. The transformation of native particles occurs through both chemogenic and mechanical processes.

Cambrian sections of the Lena Pillars National Park and adjacent areas in the south-east of the Siberian platform have been the subject of paleontological-stratigraphic, lithological, facies, paleogeographic and structural-tectonic studies. In this article we provide a detailed description of the Lower Cambrian Pestrotsvet Formation in the off-reef facies near the Oi-Muran reef massif. The description is given by the coastal outcrops of the Lena River above Sinsk village: 27 “Bachyk” (left bank), 43 and 44 (right bank). The exposed sediments in these outcrops belong to the off-reef shallow part of the open normal saline sedimentary basin adjacent to the Oi-Muran fragment (reef array) of the grand West Yakut Barrier Reef. We conducted a detailed description of the typical part of the section to identify the specifics of sediment accumulation in the Pestrotsvet Formation. A thin alternation of limestone laminae (with thickness varying from 3–5 to 10–20, less often 30–40 cm) was established. They are characterized by a light gray clean, pinkish-gray color, without visible impurities, and burgundy clay with abundant admixtures of ferruginous pigments. The individual intervals of the section are characterized by laminae of maroon marlstone. The rhythmic shift in the section of rocks of different compositions is the result of frequent, however, according geological standards, short-term transgressions and regressions. The origin of some laminae of comparatively pure gray and pinkish-gray limestones that contain abundant remains of cyanobacteria and algae is related to the rock-forming activity of these microorganisms. The materials presented in this article contribute to studies on the off-reef facies of the West Yakut Barrier Reef, one of the oldest reefs on Earth, which played a major role in the emergence of reef biota.

New data on the geological structure and petrochemical characteristics of the first kimberlite pipe in the Syuldyukar kimberlite field and its position in the Ygyatta diamond-bearing area are presented. The petrographic identification of the petrochemical varieties of kimberlites in this area was performed for the first time. The compositions of the rockforming and accessory minerals of kimberlites were studied using a modern hardware complex. The results showed that the directed change in the structural and material characteristics of kimberlites from peripheral to central parts in extended vertical bodies of the Syuldyukar tube type is expressed in the replacement of calcium kimberlites by magnesium kimberlites. Mg-kimberlites are characterized by the largest crystals of diamond, garnets, and ilmenites, high concentrations of magnesium, and a number of other components. All of these changes in kimberlites are caused by flow differentiation. This information allowed us to apply the obtained petrological results to the kimberlites of the Syuldyukar tube as search criteria for forecasting and identifying new kimberlite bodies in the Ygyatta diamond-bearing area.

This paper presents an investigation of previously unstudied soils of the Arctic islands (Krestovsky and Chetyryokhstolbovoy), which gained the status of a new protected area “Bear Islands” (70°37′–70°60′ N, 160°23′–162°33′ E). Their soils were formed mainly under permafrost conditions (approximately 1 m), with a seasonal thawing depth of 0.3–0.6 cm. The territory of Krestovsky Island is a combination of several landscapes characterized by various types of permafrost soils. Primitive gravelly soils (A–BC(C)) are exposed in mountainous areas. Permafrost tundra low-gley soils (OT–Bg–BCg(C)) are formed on the gentle long slopes under hummocky moss-herbaceous tundra. In natural depressions on cryogenic forms of surface, the soil cover represents a combination of permafrost arctotundra gleyic (O–B–Bg(BC)┴) and humus-gley soils (O–AH–AB–BG┴). Marsh soils (Ad–C(AC)–C′) occur along the low flooded gently sloping coasts of the island. All soils are acidic. Zonal types are characterized by gleying, which brings them closer to the soils of the mainland. The soil cover of Chetyryokhstolbovoy Island, with the most fully developed shrublichen-moss or forb-moss soils, is rather monotonous. Namely it is represented by arctotundra gleyic soils with a profile of the same type in terms of morphological features and physicochemical properties (О–Аd–АВ(g)–Вg(BCg)). The main features of this soil type include the thinness of the surface organogenic horizon, good decomposition of organic matter, high and medium content of humus in the soddy-humus horizon, the absence of surface gleying or its weak severity due to drying out in summer.

Background Urinary albumin excretion has been associated to cardiovascular events and increased mortality in hypertensive patients. There is limited information among Nepalese patients about the implications of microalbuminuria (MA) in the setting of hypertension and potential cardiovascular morbidity.

Objective To investigate the prevalence of microalbuminuria in patients with essential hypertension and its connection with left ventricular hypertrophy (LVH) and carotid artery intima-media thickness (cIMT).

Method The study involved 80 hypertension individuals in total. All patients in the study had basic biochemical tests, routine urine evaluations, echocardiography, and carotid artery intima-media thickness measurements performed, and the data were analyzed.

Result The prevalence of microalbuminuria was present in 37.5% cases of essential hypertension. The mean left ventricular mass index (LVMI) was significantly higher in patients with increased microalbuminuria as compared to patient with normal microalbuminuria. In addition, a significant positive correlation between microalbuminuria and left ventricular hypertrophy was also observed. Furthermore, mean carotid artery intima-media thickness was found to be higher in patients with microalbuminuria (p < 0.001), with 76.7% of the patients with microalbuminuria having elevated mean carotid artery intima-media thickness. The carotid artery intima-media thickness had a positive correlation with both microalbuminuria and left ventricular hypertrophy.

Conclusion Microalbuminuria assessment in hypertensive patients is an important test for the evaluation of target organ damage. This study shows that microalbuminuria is common in hypertension patients, particularly those with left ventricular hypertrophy. Microalbuminuria was found to be associated with left ventricular hypertrophy and carotid artery intima-media thickness.
