Published: December 2021

The temperature anomaly formation in the West Sumatra and South Java Waters plays an important role in the formation of the Indian Ocean Dipole (IOD). There have not been many detailed studies on the evolution of temperature anomalies in the subsurface layers in the area during the IOD events. In this study, temperature data from the HYCOM were used to examine the evolution of temperature anomalies on the surface and subsurface in the event of negative IOD (nIOD) 2010 and positive IOD (pIOD) 2012). The analysis was done using a cross-section plot and a Hovmöller diagram. It has shown that in the negative IOD 2010, a positive temperature anomaly in the subsurface layer was started four months earlier than the surface layer and ended six months after the IOD event. In contrast to positive IOD 2012, a negative temperature anomaly formed in the surface layer seven months earlier, and then move to the deeper layer coincide with the onset of the positive IOD event. The negative anomaly in both layers was simultaneously over two months after the positive IOD event over. The La-Niña phase that coincides with the positive or negative IOD event, influences the process of forming temperature anomalies in the subsurface layer, which in this case supports (inhibits) the formation of positive (negative) temperature anomalies in negative (positive) IOD event. The temperature anomaly in the subsurface layer can be an alternative indicator in identifying and predicting IOD events.

Introduction and objective: Asthma, is the most common chronic inflammatory disease in childhood period. It can affect the daily life to an advanced level and may become vital. The purpose of this study is to compare physical fitness and anaerobic capacity in asthmatic children (AC) and non-asthmatic children (NC).
Materials and methods: A total of 47 children participated in the study; 25 individuals with mild to moderate asthma and 22 healthy children were assessed. The assessed variables consist pulmonary function and peripheral muscle strength (PMS). Additionally, physical fitness was evaluated by using fitnessgram test battery, which includes body composition, modified shuttle walk test (MSWT), curl-up test, push-up test, and sit and reach test variables. Anaerobic capacity was measured with wingate anaerobic capacity test (WAnT) and counter-movement jump (CMJ) using a tri-axial accelerometer.
Results: FEV1/FVC ratio (p = 0.01), MSWT (p = 0.001), push-up test (p = 0.01), and WAnT peak power (p = 0.05) were measured significantly to be found reduced in AC compared with that of NC. Between the two groups, PMS, curl-up test, sit and reach test, and CMJ were not significantly different (p = 0.05). High to moderate positive correlation was found among WAnT, CMJ parameters and FEV1, fat-free body mass (FFM), dominant handgrip, and quadriceps strengths (p = 0.05).
Conclusions: Physical fitness level and anaerobic capacity were lower in AC compared with that of NC. Physical fitness parameters and anaerobic exercise capacity should be evaluated on the physiotherapy and rehabilitation program in AC.

Published: December 2021

Kon Ka Kinh National Park (KKK NP) is a priority zone for biodiversity protection in Vietnam as well as ASEAN. In order to survey the current fauna species diversity in the southern part of the KKK NP, we conducted camera trapping surveys in 2017, 2018, and 2019. 28 infrared camera traps were set up on elevations between 1041 to 1497 meters. In total, there were 360 days of survey using camera trap. As result, we recorded a total of 27 animal species of those, five species are listed in the IUCN Red List of Threatened Species (IUCN, 2020). The survey results showed a high richness of wildlife in the southern park region, and it also revealed human disturbance to wildlife in the park. The first-time camera trap was used for surveying wildlife diversity in the southern region of the KKK NP. Conducting camera trap surveys in the whole KKK NP is essential for monitoring and identifying priority areas for wildlife conservation in the national park.

Published: December 2021

Different forest vegetations provide herbivorous small mammals with different resources, forcing adaptation since food habits depend on available resources. We expect differences in vegetation to be reflected in the size and shape of the skull and mandible as a result of potentially different feeding resources. Therefore, we analyzed the craniomandibular characteristics of Pallas’s squirrel (Callosciurus erythraeus) in Vietnam. This species commonly occurs in different vegetations in Vietnam, making it a good model for examining morphological adaptation to vegetation type. We analyzed morphologically the skulls and mandibles of 156 specimens collected from 31 localities in Vietnam from 1960 to the present. Principal component analysis showed that females occurring in the tropical lowland evergreen rain forest were clearly separated from those in other vegetations.

Published: December 2021

Phytoplankton species composition, abundance, biodiversity indices and their influence by environmental conditions were examined in Thi Nai lagoon using data from four surveys in 2004, 2008, 2009 and 2020. A total of 367 taxa of phytoplankton belonging to ten groups was recorded, of which diatoms were dominant with over 60% of the total species. In Thi Nai lagoon, the number of phytoplankton species decreased from the upper lagoon (283 taxa) to the lagoon mouth area (224) and was lowest in river stations (139). The species number was much lower in the rainy season (<95 species) and increased from 2004 to 2020. Among the biodiversity indices, Shannon, ∆, s∆+, Λ+ and sФ+ were lower in the rainy season, whereas ∆*, ∆+ and Ф+ had lower values in the dry season. For long-term analysis, the differences were especially significant at upper and lower lagoon for ∆, ∆*, ∆+, s∆+ and sФ+. In the dry season, the mean density of phytoplankton was lower at the river stations and upper lagoon, but higher at the lower lagoon and the lagoon mouth area. There was a clear difference of species assemblages between the two seasons with average dissimilarities in each area ranging from 94.16% to 95.57%. During 2004–2020, the difference in ratios between the main phytoplankton groups were small over years but there was a complete change in dominance of particular species, assemblage dissimilarities were from 73.4 to 77.9, greatest between 2009 and 2020. The lagoon was low in biodiversity for the whole investigated time indicated by taxonomic index ∆+. Among biodiversity indices, species richness (S), taxonomic indices (∆*, s∆+), and phylogenetic indices (Ф+, sФ+) were more sensitive to the changes of the aquatic environment than other traditional indices.

Published: December 2021

Panax vietnamensis Ha et Grushv. is a species of the genus Panax native to Central Vietnam, containing a family of triterpene saponins named ginsenosides. This group of biomolecules possesses valuable therapeutic properties against cancer, hepatitis, diabetes, inflammation as well as stress and anxiety. Farnesyl diphosphate synthase (FPS) is a key enzyme participating in the ginsenoside biosynthesis pathway. In this study, a FPS gene from P. vietnamensis (PvFPS) was isolated and characterized. The PvFPS cDNA contained an open reading frame of 1032 bp, encoding a polypeptide chain of 342 amino acid residues. Nucleotide sequence comparison showed that FPS was highly conserved among most species, with two Aspartate-rich motifs responsible for product chain length determination strongly sustained. PvFPS was closely related to those of the same genera and order and differed from those from other kingdoms. PvFPS expression was detected at a greater level in root tissues than in leaves in all ages. Our findings provided information concerning the properties of a crucial gene in the ginsenoside biosynthesis, thus enhancing our understanding of this important pathway.

Cardiac Arrest due to Carbon Dioxide Embolism During Laparoscopic Gynecologic Surgery of a Patient with Previous Abdominal Surgery: A Case Report
Authors: Kim Nan Seol
Published: December 2021

Catastrophic carbon dioxide (CO2) embolism is a rare, but potentially life-threatening, the complication of laparoscopic gynecologic surgery. We report the case of a healthy 53-year-old woman who developed CO2 embolism and cardiac arrest during laparoscopic surgery. She had a history of two cesarean sections and had extensive peritoneal adhesions. After placement of the trocar and insufflation of CO2, end-tidal CO2 dropped from 35 to 15 mm Hg, and the patient had a cardiovascular collapse. In this patient, CO2 embolism was diagnosed on the basis of a sudden decrease in end-tidal CO2, hypotension, and hypoxemia. The patient was managed quickly and aggressively. The patient recovered completely following the treatment for CO2 embolism, with no cardiopulmonary or neurological sequelae. There is an increased risk of catastrophic CO2 embolism during laparoscopic gynecologic surgery in patients with previous abdominal surgery. Therefore, the surgeon and anesthesiologist should remain vigilant to promote early detection of CO2 embolism.

Published: December 2021

A key challenge of anesthesia is to provide patients with safe and optimized anesthetic management to improve prognosis and minimize mortality and morbidity. To this end, the anesthesiologist should comprehensively understand the patient’s physical status through pre-anesthetic assessment and carefully monitor the patient during surgery. Several types of novel patient-monitoring devices may be useful to achieve this purpose. We report a case of anesthetic management in a patient with left internal carotid artery occlusion and penetrating aortic ulcer.

Published: December 2021

The population migration has attracted attention for more than a decade. As migration consequences differ in terms of characteristics and directions, governments worldwide are looking for solutions to regulate migration flows. The study aims to systematise push-pull factors of migration by analysing existing cases, as well as to build a model for predicting migration considering the quantitative interpretation of such factors. While migration factors are quite similar regardless of the country of residence, their main differences are compatibility and hierarchy. The most frequently mentioned factors include the expectation of income increase, improvement in the quality of life, professional aspects. Simultaneously, a certain pattern emerges: if a migrant’s material and economic needs are satisfied in the country of departure, they pay more attention to intangible/non-economic benefits (quality of life, infrastructure, etc.). A dynamic forecasting model for scientific migration has been developed based on the theory of positional games. The model demonstrates the changes in migration flows by describing the behaviour of a rational individual who seeks to maximise benefits from migration. The result of the simulation is a short-term forecast of trends in scientific migration of Ural scholars to key migration countries. The model predicts the intensification of migration flows to the leading Asian countries, their alignment with flows to America, and a decrease in migration to European countries. This forecast is characterised by a direct dependence of the dynamics of scientific migration flows on the socio-economic development of migration destinations. Practical implications of this study include the development of a predictive model describing migration flows in the short term as an analytical tool and systematisation of pull-push factors as key indicators for managing the migration flows of scientists. In addition, the research proposes measures positively affecting the balance of scientific migration.

Published: December 2021

Since 2008, Russia has been conducting special surveys on the occupational structure of employed in the form of a federal statistical observation «On the number and needs of organisations for employees by professional groups». The present study aims to assess the data obtained from this observation for 2008–2018, as well as to compare the methodologies of Federal State Statistics Service (Rosstat) and the International Standard Classification of Occupations (ISCO-08). The impact of such relevant skills as emotional intelligence and data literacy on vocational training and the emergence of new professions associated with information economy is discussed. The comparative analysis demonstrated that the economy demands highly-qualified specialists in all Russian regions. Simultaneously, the research revealed the impossibility of considering the specificity of regional structures due to the insufficiency of information for predictive assessments of structural changes and the lack of data on occupations in small business and financial and social insurance sectors. According to the analysis of the dynamics of vacancies for various groups of occupations, the linear trend in the total amount of vacancies tends to decrease. The absence of relevant regional data prevents an in-depth analysis of regional differences and the construction of econometric models to identify the reasons for these differences. Additionally, it is impossible to assess the determinants of the lack of qualified staff by professional groups in Russian regions without these data. The study concludes that researchers and experts, using the Rosstat methodology, should not synonymise the concepts of occupation, speciality and type of activity. The research results can be used to expand Rosstat’s survey of occupations, in particular, its database for Russian regions, as well as to improve the methodology for statistical observation of occupational structure of the employed.

In the context of digital transformation of the economy, human capital development depends on differences in earnings. Previous studies examined the relationship between wage differentiation and employee competencies without considering the regional digitalisation. The present research tests a hypothesis of the dependence of wage differentiation on individual digital competencies, likelihood of job computerisation and digital development of a region. Linear regression method based on Mincer equations was utilised. The empirical basis comprises data from the Russia Longitudinal Monitoring Survey — Higher School of Economics (RLMS-HSE) and statistics of the Federal State Statistics Service on the digitalisation of Russian regions in the period from 2003 to 2018. Development opportunities and threats have been conceptually identified in terms of substitution and supplementation of labour, distribution of entrepreneurial risks, the use of digital competencies and the influence of regional digitalisation on differences in individual earnings. The revealed professional polarisation of the Russian labour market due to digitalisation creates unequal opportunities for income growth and professional development in the mid-term. In contrast to previous studies, this research analysed how the likelihood of computerisation affects wages, showing that while, in general, digitalisation creates an advantage for human capital, an increase in computerisation reduces earnings by almost a quarter. High level of digitalisation of certain regions supports human capital, yielding a wage increase of 5–10 % on average. The study results can be practically applied to support strategic decisions for the development of digitalisation at the local and regional levels. Moreover, the necessity to monitor professions under the threat of digital automation in regions is shown.
External and Internal Trade Barriers of the Russian Far East
Authors:   Economic Research Institute of Far Eastern Branch of RAS, Izotov D.A.
Published: December 2021

Recently, the Russian Far East has been receiving close attention from the government of the Russian Federation. Accelerated economic development of the Far Eastern regions requires trade intensification with foreign and domestic markets, which implies a reduction of various barriers. The study aims to assess the external and internal trade barriers of the Russian Far East using a consistent dataset and relevant econometric model for estimations. The assessment of trade barriers, expressed as values of the relative trade intensity and transport costs in the framework of modern gravity models, confirmed the trade bias of the Russian Far East in favour of the domestic market in the long term. High values of relative transport costs were offset by a high relative trade intensity between the Russian Far East and the domestic market. The conducted analysis shows that the reduction of external trade barriers between the Russian Far East and foreign markets can significantly increase their turnover. The obtained estimates revealed a trend of linking the regions of the Russian Far East to the domestic market due to the barrier reduction in the form of transport costs. This study can be further developed, as the presented methodology for qualitative assessment of internal and external barriers can be applied to analyse the costs of trade in commodity markets, to decompose export and import barriers, as well as to determine the potential for expanding regional trade with foreign countries.

Considering the widespread of Covid-19 and its impact on the population health in Russian regions, it is necessary to examine the impact of the pandemic (as excess mortality) on the regional socio-economic development in 2020. Based on a quantitative and qualitative model, the study explains the process of coronavirus diffusion at the regional level, using information from foreign publications, Russian regional statistics and a database of legal documents «Consultant +». The concept of spatial diffusion, developed in the 1950s-1980s, was chosen as the research methodology. The study methods include a cartographic analysis of the monthly dynamics of coronavirus spread in Russian regions and regression analysis of regional differences in excess mortality regarding the most significant explanatory variables. The developed regression model explains the spread of Covid-19 across Russian regions in 2020, while the proposed qualitative model «network-place-scaling» describes the spatial diffusion of the virus. The conducted analysis confirmed the relationship between the spread of the virus and economic specialisation of regions. Simultaneously, such widely discussed factors as physical density, urbanisation level and per capita income did not show significant correlation with excess mortality. The study revealed the following results. There is a significant discrepancy between the actual situation in Russian regions and expected developments according to the simplified centre-periphery model. The important regression variables, explaining the interregional differences in excess mortality in 2020, include the share of employed in contact-intensive wholesale and retail trade and manufacturing (large production teams); proportion of the population over 65; the number of retail facilities per 1000 people. The qualitative model «network-place-scaling» was deemed suitable for explaining the mechanisms of the spread of coronavirus in Russian regions. Future studies should focus on examining the mechanisms and socio-economic consequences of the pandemic at the municipal level of large cities and urban agglomerations in Russia.

Sustainable development was chosen by the United Nations as the key concept of the future in the 21st century, which led to the emergence of other economic concepts, such as green and blue economy, seen as contributing to the achievement of sustainable development goals (SDGs). In Russia, despite the ongoing processes of green transformation in some economic sectors and certain improvements in the green legislation and green finance, not all businesses and regions are ready to embrace sustainable development. This paper discusses two interconnected aspects of regional economic systems — their economic efficiency and environmental impact. The analysis focuses on the regions of the Ural Federal District and explores these regions’ transition to sustainable development by looking at their eco-intensity. Methodologically, the study relies on the methods of analysis and synthesis, statistical, comparative and causal analysis. Conceptually, we use the theoretical framework of sustainable development as a point of departure for our discussion. The results have shown, on the one hand, a decrease in the industrial pressure on the natural environment, related primarily to the enhanced resource efficiency of certain industries. On the other hand, less effort is now invested into minimising the negative impact on the environment in Ural regions. We have also identified those areas of sustainable development that hold most promise in the Russian context. Our findings can serve as a basis for the strategies of regional sustainable development and may be used for further research on socio-environmental and economic sustainability.

Global climate change threatens the continued existence of mankind. The rate of warming in Russia, which is 2.5 times higher than the rate of growth of the global average temperature, can lead to huge environmental and financial losses. Thus, it is increasingly necessary to modernise and develop methods and tools for adaptive regulation of national climate policy to increase its efficiency at the regional and federal levels. To this end, the methods of content analysis, grouping, modelling, comparative and correlation analysis, as well as an information asymmetry approach were used in the research. The paper substantiates the necessity of a transition from autarky and directionality to the integration of regions and the federation based on adaptation and preventive measures. The periodic assessment of climate change and relevant contributing factors should be replaced by the continuous management and regional monitoring of climate risks. Stressing the importance of transparency and comparability of information on climate risks, the research distinguished anthropogenic risks, risks of reducing the quality of life and moral climate risks. In order to promote climate preservation, an organisational and economic mechanism for the implementation of climate policy was developed, whose main function is the regional environmental management. Assessment of the decoupling effect and ranking of the constituent entities of the Russian Federation in terms of the relationship between energy intensity and climate intensity proved the feasibility of using the proposed indicators to increase the efficiency of the organisational and economic mechanism. Regulatory and financial support for the mechanism can be provided by introducing a quota market, green certificates and bonds, insurance and risk hedging strategies based on a scenario approach and online-management models. The research results can be used for the digitalisation of national climate policy, as well as for the development of regional and municipal climate strategies, programmes, projects.

Published: December 2021

Background: We aimed to explore the distribution of intraoperative lactic acid (LA) level during liver transplantation (LT) and determine the optimal cutoff values to predict post-LT 30-day and 90-day mortality.Methods: Intraoperative LA data from 3,338 patients were collected between 2008 to 2019 and all-cause mortalities within 30 and 90 days were retrospectively reviewed. Of the three LA levels measured during preanhepatic, anhepatic, and neohepatic phase of LT, the peak LA level was selected to explore the distribution and predict early post-LT mortality. To determine the best cutoff values of LA, we used a classification and regression tree algorithm and maximally selected rank statistics with the smallest P value.Results: The median intraoperative LA level was 4.4 mmol/L (range: 0.5–34.7, interquartile range: 3.0–6.2 mmol/L). Of the 3,338 patients, 1,884 (56.4%) had LA levels > 4.0 mmol/L and 188 (5.6%) had LA levels > 10 mmol/L. Patients with LA levels > 16.7 mmol/L and 13.5–16.7 mmol/L showed significantly higher 30-day mortality rates of 58.3% and 21.2%, respectively. For the prediction of the 90-day mortality, 8.4 mmol/L of intraoperative LA was the best cutoff value.Conclusions: Approximately 6% of the LT recipients showed intraoperative hyperlactatemia of > 10 mmol/L during LT, and those with LA > 8.4 mmol/L were associated with significantly higher early post-LT mortality.

The treatment and disposal of domestic sewage is one of Brazil's main challenges. Sewage composition varies with the habits of the population and the frequency with which new contaminants are released into the environment. This study is a bibliographical review of the main aspects related to the characterization and composition of sanitary sewage, types of sewage treatment systems and pertinent legislation; and toxicity of domestic effluents. The review was based on publications available on Science Direct, Google Scholar and Scielo, as well as on printed publications, relevant legislation, and normative instructions. The research period adopted for the selection of publications was from 2005 to 2021. We found out that, in addition to the levels of organic matter from domestic sewage, residues from products used in daily life, such as pharmaceuticals and cleaning products, can be found in effluents in concentrations harmful to the environment. Often, the types of treatment used in municipal sewage treatment plants do not efficiently remove these contaminants. Thus, even if sewage is treated to meet the limits required for the physical-chemical and biological parameters established by law, domestic effluent can present a high potential for toxicity to various aquatic species such as microcrustaceans, mollusks and fish. Thus, ecotoxicological analyses represent a remarkable mechanism for indicating the efficiency of removal of emerging contaminants present in treated sanitary effluent, in addition to indicating the deleterious effects caused by these residues to the environment and ecosystems associated with the receiving water body.

This pandemic portrayed the country's social and economic inequality in terms of health services, work and social distancing. It was found that the spread of Covid-19 on a global scale is favored by the circulation of infected people and/or objects; changing the circulation in many land and air borders that needed to have restricted and/or closed accesses, including, the reduction and even the suspension of travels inside and outside countries, whose displacements are by road, rail, river and sea. In view of this, the search for measures to face the pandemic within the various socio-economic contexts, such as in this case of urban mobility, for example, the occupancy limit of 50% of seats in intercity transport and the mandatory use of masks. Urban mobility permeates as a social right and essential service, which needs to continue to function with due health care. It is necessary to maintain social distance and take due care. For the country to remain in this confrontation, it is necessary to guarantee democratic access to the city, together with measures to protect social actors from contamination by the New Coronavirus.

Las cartas Patrimoniales y las Teorías de Restauración desarrolladas a lo largo de los años son de suma importancia para la realización de proyectos de restauro en edificios patrimoniales. Comprendiendo la necesidad de que estos proyectos están vinculados a estas teorías, se tiene como objetivo analizar la intervención de restauro y rehabilitación realizada en la Manzana de San Francisco en Buenos Aires, Argentina, a partir de las Teorías de Restauración y las Cartas Internacionales del Patrimonio. La metodología empleada es la arquitectura dialógica, a través de una verificación de los criterios usados en la rehabilitación de la Manzana de San Francisco (Texto) con las recomendaciones de las Cartas Internacionales del Patrimonio y las Teorías de Restauración (Contexto). Los resultados mostraron  que el proyecto fue elaborado siguiendo las recomendaciones de la Carta de Venecia (ICOMOS, 1964), Carta de Atenas (NAÇÕES, 1931),  y Carta del Restauro (ITALIA, 1972), así como, en la Teoría de la Restauración Crítica de Brandi en los criterios de: usos, estilos arquitectónicos, conservación, diseño del conjunto, espacialidad, tipologías, sistemas constructivos y materiales, acabados y flexibilidad, pero difiere de las recomendaciones de restauro de la Carta del Restauro de 1972.

Wound healing is a complex and dynamic process that includes multiple biological pathways and has some successive healing periods. Most growth factor is responsible for wound healing. Fibroblast growth factor has a positive effect on wound healing problems that can be caused by diabetes. In the present study, we aimed to investigate exogenous effect bFGF supplementation on serum TBARS, RSH and NOx levels in hyperglysemic rats. Experiments were performed on 30 male Wistar albino rats (weight range: 200-250 g ). Rats were hyperglycemic with STZ (ip, 60 mg/kg). The experimental groups were divided into untreated and bFGF-treated subgroups. bGF was applied locally to the dorsalateral wounds of rats (10 ng/ml). After these administrations, on the 3th and 7th days of wound healing, the animals were sacrificed. Serum TBARS, RSH and NOx levels were recorded spectrophotometrically. The results were expressed as mean ± Standard deviation and the mean differences were compared by Anova Variance Analysis (p<0,05). When compared with the treatment group, on the 7th day and the 3rd day, it was found that the serum TBARS levels increased statistically in hyperglycemic rats(p<0,05). Both in the 3rd day of the untreated and 3rd day of the rats treated with bFGF may significant decrease in the serum RSH levels. bFGF application was found both enhancing and reducing effects on oxidative stres. In subsequent studies, the effect of bFGF, which has positive effects on diabetic wound healing, on oxidative events can be investigated in detail using different doses and different treatment periods.
Bioadsorbent Efficiency in Heavy Metal Removal from Aqueous Solutions: Adsorption Kinetics, Isotherm, and Thermodynamics

Heavy metals are major pollutants in marine, soil, industrial, and even treated wastewater. These metals are transported by flowing waters and polluted water sources downstream of the industrial site. Mercury is an extremely toxically heavy metal. Mercury, on the other hand, is an extremely toxically heavy metal. Mercury spillage is hazardous for it destroys the tissue, lungs, brain, and can affect the nervous systems and kidney, causing some diseases. Therefore, removing Hg (II) from drinking water, aqueous solutions is very important in wastewater treatment and hydrometallurgical. Diverse process has been suggested to eliminate Hg (II) ions from wastewater. The adsorption method is used as a low-cost, efficient, and effective technique for removing toxically heavy metals from wastewater. Researchers have turned to inexpensive adsorbents such as vegetable wastes. This study aimed to remove Hg (II) ions from wastewater by using ground rice grains as adsorbents. The suitability of different isotherm and kinetic models for the adsorption process was researched. It was determined that the Langmuir isotherm best describes the adsorption equilibrium process, and the pseudo-second-order kinetic model is the most suitable model for adsorption. As a result of the analysis of thermodynamic parameters, it was concluded that the adsorption mechanism is self-progressing and endothermic. The data obtained show that rice grains can be considered a cheap, practical, and effective adsorbent for Hg (II) adsorption from wastewater.

Lake Tuz is in a closed basin, in the center of the Anatolia (Turkey). The lake has shallow hypersaline water. In this study, mineralogical and geochemical features of the lake sediments sampled by core drillings were investigated. Halite, polyhalite, calcite, magnesite, dolomite, huntite, quartz, and albite minerals were found in bulk sample and montmorillonite and vermiculite minerals were found in the clay fraction XRD analyzes. In geostatistical evaluations, elements are divided into four clusters. These clusters are named as Clastic, Hydrothermal, Evaporite-carbonate and Evaporite-sulphate. Trace elements included in the clastic cluster were used to interpret provenance. The Light Rare Earth Element (LREE) enriched chondrite normalized average REE pattern suggests a cratonic provenance for the lake sediments except for the low negative Eu anomaly. Trace element ratios of La/Sc, La/Co, Th/Sc, Th/Co, Zr/Sc, Zr/Co, Ba/Sc, and Ba/Co, which are critical for provenance, show a provenance in a “felsic-intermediate magmatic” composition. According to the La-Th-Sc diagram, the tectonic setting of the source area was found as "Continental Island Arc".
