AB  - Tufa accumulations from the Gostilje River Basin and the Sopotnica River Basin in SW Serbia are represented by both active and fossil tufa precipitates. The aim of this study is to distinguish and describe different tufa facies and to determine the environmental conditions, based on stable isotope data. We also compare our analysis with other tufa deposits in Europe. Four facies are distinguished: moss tufa, algal tufa, stromatolitic laminated tufa, and phytoclastic tufa. The dominant constituent of all tufa samples is low Mg-calcite, whereas the presence of sylvite is noted in two samples from the Gostilje River Basin. The δ18O values range from −9.07‰ to −10.79‰ (mean value: −9.81‰), while the δ13C values range from −6.50‰ to −10.34‰ (mean values −9.01‰). The stable isotope values (δ13C and δ18O) indicate that these tufa deposits were precipitated from cold, ambient water supported by CO2 of an atmospheric origin. We emphasize that this is the first data about stable isotope analyses of tufa deposits from Serbia.

AB  - Given the widespread use of dietary supplements (DS) and herbal products (HP), healthcare professionals (HCPs) will increasingly encounter patients who use these preparations with conventional drugs and who need their services to reduce the consequences of adverse therapeutic outcomes. The aim of our survey was to assess the knowledge and behaviors of HCPs regarding the risk of potential drug–dietary supplement (DDSIs) and drug–herbal product (DHPIs) interactions. This cross-sectional survey collected data via on paper-based questionnaire among general practitioners (GPs) (n = 105), specialty doctors (n = 87) and nurses (n = 154). The HCPs were mostly familiar with the interaction of doxycycline with magnesium (83%) and were least familiar with interaction of warfarin with glucosamine (14%). The results on DDSIs and DHPIs knowledge showed that GPs scored significantly higher than nurses (p < 0.001 and p = 0.003, respectively), while specialty doctors scored significantly higher than nurses only on DDSIs knowledge (p < 0.001). Only 28% of respondents reported that they often or always ask patients on drug therapy about the use of DS or HP, and 25% of respondents record such data in the medical documentation of patients. Our results showed that HCPs have sufficient knowledge about most major DDSIs and DHPIs, but insufficient knowledge about most moderate interactions. However, their overall knowledge and behavior regarding the risk of these interactions indicate the need for further continuing education and training

AB  - The Updated Trewartha climate classification (TWCC) at global level shows the 
changes that are expected as a consequence of global temperature increase and 
imbalance of precipitation. This type of classification is more precise than the 
Köppen climate classification. Predictions included the increase in global tem perature (T in °C) and change in the amount of precipitation (PA in mm). Two 
climate models MIROC6 and IPSL-CM6A- LR were used, along with 4261 mete orological stations from which the data on temperature and precipitation were 
taken. These climate models were used because they represent the most extreme 
models in the CMIP6 database. Four scenarios of climate change and their terri tories were analysed in accordance with the TWCC classification. Four scenarios 
of representative concentration pathway (RCP) by 2.6, 4.5, 6.0 and 8.5 W/m2
 fol low the increase of temperature between 0.3°C and 4.3°C in relation to precipita tion and are being analysed for the periods 2021–2040, 2041–2060, 2061–2080 and 
2081–2100. The biggest extremes are shown in the last grid for the period 2081–
2100, reflecting the increase of T up to 4.3°C. With the help of GIS (geographical 
information systems) and spatial analyses, it is possible to estimate the changes in 
climate zones as well as their movement. Australia and South East Asia will suffer 
the biggest changes of biomes, followed by South America and North America. 
Climate belts to undergo the biggest change due to such temperature according to 
TWCC are Ar, Am, Aw and BS, BW, E, Ft and Fi. The Antarctic will lose 11.5% of 
the territory under Fi and Ft climates within the period between 2081 and 2100. 
The conclusion is that the climates BW, Bwh and Bwk, which represent the de serts, will increase by 119.8% with the increase of T by 4.3°C

AB  - The persistence of the SARS-CoV-2 virus imposed vaccination passports for traveling in most countries. We investigated psychological factors that predict the intention to vaccinate for travel. In a cross-sectional study, we examined how demographic variables, vaccination status, perceived risk of infection and severity of disease contracted at travel destination, safety and effectiveness of vaccines against contracting COVID-19 during travel, and conspiracy beliefs are related to intention to vaccinate for travel. Further analyses involved differences between vaccinated and unvaccinated individuals in a Romanian sample regarding conspiracy beliefs, attitudes about vaccines, and self-efficacy of controlling COVID-19 infection. Results showed that the intention to vaccinate for travel reasons is best predicted by vaccination status and perceptions of safety and efficacy of vaccines against COVID-19. Thus, vaccinated individuals believing that vaccines are safe and effective most probably will take another vaccine booster if it will allow them to travel. Positive relationships of the intention to vaccinate for travel reasons were found with age, vaccination status, conspiracy beliefs, perceptions of safety and effectiveness of vaccines, intention to travel, and a more cautious approach to travel. No significant relationships were found between perceptions of risk for self or for transmitting the disease to others, severity of disease, and the intention to vaccinate for travel. We also found significant differences between vaccinated and unvaccinated participants, as unvaccinated participants showed higher levels of conspiracy beliefs and less trust in the safety and efficacy of vaccines. We conclude that campaigns focused on promoting information on the safety and efficacy of vaccines is the most important direction for promoting vaccination in young travelers

AB  - Тhe contemporary globalized world characterizes the rapid population growth, its significant concentration in cities, and an increase in the urban population. Currently, many socio-cultural, economic, environmental, and other challenges are arising in modern cities, negatively affecting the state of the urban environment, health, and quality of life.There is a need to study these problems in order to solve them. Urban Green Areas (UGAs) are a part of the social space and a vital part of the urban landscape. They act as an environmental framework of the territory and a factor ensuring a more comfortable
environment of human life. This study aims at substantiating the importance of the UGAs, identifying the spatiotemporal dynamics of their functioning, and transforming
changes in their infrastructure given the expansion of their functions. This research was carried out as a case study of the second city in Ukraine, Kharkiv. The authors developed and used an original integrated approach using urban remote sensing (URS) and GIS for changes detection to evaluate the current state and monitor spatial transformations of the
UGAs. We used several GIS platforms and online resources to overcome the lack of digital cadastre of the thematic municipal area of Kharkiv. This resulted in the present original
study. The study analyses the dynamics of the spatial and functional organization of the UGAs according to the Master Plans, plans, maps, and functional zoning of the city for the
period from 1867 to 2019. The peripheral green areas became important after the large scale development of the extensive residential areas during the rapid industrial development in remote districts of the city. They provide opportunities for population recreation near living places. Central UGAs are modern, comprehensively developed clusters with multidisciplinary infrastructure, while the peripheral UGAs are currently being developed. The use of URS/GIS tools in the analysis of the satellite images covering 2000–2020 allowed identifying the factors of the UGAs losses in Kharkiv and finding that UGAs were not expanding and partially shrinking during the study period. It is caused by the intensive construction of the residential neighborhoods, primarily peripheral areas, infrastructure development, and expansion of the city transport network. Nonetheless, some sustainable trends of UGA functioning without more or less significant decrease could be proved as existing in a long-term perspective. The authors analyzed and evaluated changes and expansion of the UGAs functions according to modern social
demand. The research value of this is the usage of different approaches, scientific sources, URS/GIS tools to determine the UGAs transformation in the second-largest city in Ukraine
(Kharkiv), to expand and update the main functions of UGAs and their role in the population’s recreation. The obtained scientific results can be used to update thefollowing strategies, programs, and development plans of Kharkiv.

AB  - Snow avalanches are one of the most devastating natural hazards in the highlands that often cause human casualties and economic losses. The complex process of modeling terrain susceptibility requires the application of modern methods and software. The prediction of avalanches in this study is based on the use of geographic information systems (GIS), remote sensing, and multicriteria analysis—analytic hierarchy process (AHP) on the territory of the Šar Mountains (Serbia). Five indicators (lithological, geomorphological, hydrological, vegetation, and climatic) were processed, where 14 criteria were analyzed. The results showed that approximately 20% of the investigated area is highly susceptible to avalanches and that 24% of the area has a medium susceptibility. Based on the results, settlements where avalanche protection measures should be applied have been singled out. The obtained data can will help local self-governments, emergency management services, and mountaineering services to mitigate human and material losses from the snow avalanches. This is the first research in the Republic of Serbia that deals with GIS-AHP spatial modeling of snow avalanches, and methodology and criteria used in this study can be tested in other high mountainous regions.

AB  - World production growth affected a rise in the amount of waste generated. In these circumstances proper waste management becomes a highly important issue. The protection of the environment from degradation requires a multi-dimensional approach to this problem. Integration of multicriteria decision making with the geographic information systems provides a useful methodology and a helpful instrument in waste management, particularly in the assessment of environmental suitability for the location of municipal solid waste disposal sites. Multidimensional approach is realized through analytic hierarchy process (AHP) in the determination of sub-criteria and criteria values and final site selection. Geographic information systems (GIS) provide spatial data input and give an insight into final result of the decision-making process. Integrated methodology is applied in suitability analysis of the City of East Sarajevo for the location of municipal solid waste disposal site (MSWDS). Ten criteria were evaluated through pair-wise comparison matrices and suitability map was obtained using weighted linear combination algorithm in GIS. Extracting high suitability area, the largest locations were evaluated through AHP according to ten criteria and final site selection was made. The results indicate high applicability of integrated multi-criteria analysis and GIS methodologies for coordination of decision-making process in spatially oriented issues of environmental management.

AB  - Climate change is one of the largest environmental issues causing hydroclimatological extremes such as floods, droughts, and aridity. The aim of this study is to assess the observed and projected climate changes in Bačka (Serbia). Detailed trend analyses and possible climate scenarios over Bačka has not been presented up to now. In this paper, four data sets were extracted and calculated: mean annual air temperature, mean air temperatures during the vegetation period, mean annual precipitation and total precipitation during the vegetation period. The presented parameters were obtained from the annual meteorological reports of the Republic Hydrometeorological Service of Serbia. Trend equation based on linear regression, trend magnitude according to the trend equation, and Mann-Kendall statistics have been used for trend analysis of climatic parameters. A GIS modeling of the possible climate scenario was created according to the Beijing Climate Center Climate System Model (BCC-CSM2-MR). Based on the trend equations, positive trends related to air temperature and precipitation variables are dominant. The trend magnitude shows the largest mean increase in all time series related to air temperature during the vegetation period. The highest mean precipitation increase occurs only in two time series. The Mann-Kendall statistics showed significantly positive trends in 11 cases and no changes in 9 cases. According to BCC-CSM2-MR, changes will be especially dominant in case of air temperatures. The expected changes in the total precipitation during the vegetation period show a tendency towards semiarid conditions. The presented results of observed and projected climate changes demand adaptation measures, especially from the aspect of sustainable agriculture.

AB  - The subject of this paper is to present an investigation of renewable energy potential in one small municipality in south Serbia. Serbia has a relatively small area but a large number of renewable energy resources. This energy is divided into solar, wind, geothermal and waste wood. One municipality on the south east has very large potential for the renewable energy utilization. The municipality of Kursumlija has an area of 952 km(2) but with poor dense of the population. In this municipality we have one of the most powerful resources of the renewable energy, estimated on 118.5 MWt. With the help of different methods such as GIS (Geographical Information System), numerical and geo-statistical analyses, were analyzed total capacity of the renewable energy. Other relevant documents are the municipality strategy documents, satellite recordings, cadaster data, analogue plans and maps. The estimated capacity of geothermal energy with included 23 springs may reach 25.5 MWt. The waste wood estimated capacity is may reach 1123.5 TJ/year or 35.6 MWt. The solar potential may reach 1810.8 Tj/year or 57.4 MWt. The main goal of this research is to present renewable energy potential of the municipality and compare it with dirty kinds of energy. Other goals are to present benefits and advantages of the utilization of renewable energy sources. This research is also important to present to the broader readership and it can be the start initiative for deeper investigation of renewable energy resources.

AB  - Romania is one of the countries severely affected by numerous natural hazards, where landslides constitute a very common geomorphic hazard with strong economic and social impacts. The analyzed area, known as the "Ciuperca Hill", is located in Oradea (NW part of Romania) and it has experienced a number of landsliding events in previous years, which have endangered anthropogenic systems. Our investigation, focused on the main causal factors, determined that landslide events have rather complex components, reflected in the joint climatological characteristics, properties of the geological substrate, and human activity that further contributed to the intensive change of landscape and acceleration of slope instability. Analysis of daily precipitation displays the occurrence and intensive distribution between May and September. Higher values of rainfall erosivity (observed for the 2014-2017 period), are occurring between April and August. Erosivity density follows this pattern and indicates high intensity events from April until October. SPI index reveals the greater presence of various wet classes during the investigated period. Geological substrate has been found to be highly susceptible to erosion and landsliding when climatological conditions are suitable. Accelerated urbanization and reduced vegetation cover intensified slope instability. The authors implemented adequate remote-sensing techniques in order to monitor and assess the temporal changes in landslide events at local level. Potential solutions for preventative actions are given in order to introduce and conduct qualitative mitigation strategies for shaping sustainable urban environments. Results from this study could have implications for mitigation strategies at national, regional, county, and municipality levels, providing knowledge for the enhancement of geohazard prevention and appropriate response plans.

On the other hand, the number of urban areas has been growing. One of the main goals of former Socialist Federal Republic of Yugoslavia was the development of all the areas, including the rural ones. In the '60s and the '70s, the land with special purpose was supposed to be of the utmost importance. Urban regions were to be better connected and enlarged. The main reason for it was the distribution of economic activities as well as the process of deagrarization which had already been in progress. In 1966, the first spatial plan of a special-purpose area, being the outset of an idea in a Socialist country, was in fact the proposition of the first Yugoslav conurbation. The long forgotten project was about to be reinforced in 1996, when thirty years later the country was in a transitional period, heading towards market capitalization. After the final breakup of Yuoslavia, there was a growing need for preservation of the urban areas and large trade centers, along with the necessity of better communication among municipalities. The ambitious project in question called "Morava city", has never been brought to life. The main purpose of this manuscript is to answer the question of the actual necessity of this potential conurbation by means of GIS methodology, qualitative and quantitative techniques, and demographic and sociological factors. Accordingly, by means of spatial analysis, the communist project is placed into post-communist environment. Finally, the manuscript focuses on the relationship between rural and urban areas, traffic connectivity, geographical position, and most importantly on the sustainability and profitability of the first Serbian conurbation.

AB  - This paper points out the possibilities of better exploitation of marine traffic as well as its connection with other kinds of traffic. Special attention is given to the analysis of 1,081 harbors about their availability during the year. The methods and algorithms used in GIS are buffers, cluster, method of interpolations, and network analysis. The methods used for the purpose of conducting numerical analyses are algorithms that served for the analysis of the network, its transport features, and the connectivity with harbors in terms of geospace. The main results found in this research showed that harbors have good connectivity in the first place with road traffic and after that with air and railroad traffic. According to data from 2019, all traffic lines cover 4.1 × 1015 km, and the road traffic has the most significant potential in connection with the harbors. The most connected harbors and airports are in the east coast of North America, west coast, north Europe, southern Europe, south-east Australia, a central part of Oceania, and south-east Africa. The results in the modified Likert scale between airports and harbors showed medium results. The densest road network is located in the eastern part of USA, western and central part of Europe, and east coast of China. The number of possible connected lines between main road nodes and harbors is 0.8 × 109. This type of traffic showed excellent results and connection with harbors. The number of possible connected lines per month between railroads and harbors is 1.3 × 103. This type of traffic showed low connectivity with the harbors. In the end comparison of harbors with air, road and railroad networks were established. The geographical position of harbors was analyzed, and better understanding was performed on a global scale.

AB  - In December 2019, the virus SARS-CoV-2 responsible for the COVID-19 pandemic was detected in the Chinese city of Wuhan. The virus started to spread from China and dispersed over the rest of the world. In March 2020, WHO (World Health Organization) declared COVID-19 a pandemic. The transmission path of the pandemic was accelerated by different types of transportation. With complete analysis of spatial data, population density, types of traffic networks, and their properties, the spatial distribution of COVID-19 was estimated. GIS (Geographical Information System), numerical methods, and software for network analysis were used in this research to model scenarios of virus distribution on a global scale. The analyzed data included air, railway, marine, and road traffic. In the pandemic research, numerous models of possible trajectory of viruses can be created. Many have a stochastic character. This study includes all countries in the world affected by the COVID-19 up to date. In this study, GIS methods such as buffer, interpolations, and numerical analysis were used in order to estimate and visualize ongoing COVID-19 pandemic situation. According to the availability of new data, trajectory of virus paths was estimated. On the other hand, sparsely populated areas with poorly developed and small traffic networks (and isolated island territories) tend to be less or not affected as shown by the model. This low-cost approach can be used in order to define important measures that need to be addressed and implemented in order to successfully mitigate the implications of COVID-19 not only on global, but local and regional scales as well.

AB  - Sea surface salinity presents one of the most important chemical elements in the water. Climatic variables, included in new view of salinity distribution at a global scale, were used in this research. For the purpose of this research newly updated climate parameters for the period until 2100 were used along with (CMIP5) climatological model. The new distribution of surface salinity may show water desalination and energy potential. This map can be useful in the determination of new littoral areas or for fishermen's routes. These data are presented in geo-tiff raster extension with the resolution of 0.1. This map could be updated with climatological parameters with obtained medium climate change effects. Some places in the world sea have low, some have high salinity. Salinity increases in accordance with the increase of precipitation and decreases with the decrease of it. The paper presents following maps; salinity world map when there is no climate change; the moderate one, if the temperature increases for 2.0 degrees C until 2100, and high if the increase of temperature was between 2.0 degrees C and 5.0 degrees C. The three scenarios were taken to show updated maps of world salinity in comparison with climate change effects.

AB  - With the help of satellite data and numerical geographical information system (GIS) methods, the total capacity of dew volume on the entire territory of the Republic of Serbia was estimated. Multicriteria GIS analysis and satellite detections with the support of methods such as kriging and semi-kriging gave satisfactory results in the present research. After the download of satellite data, they were compared with meteorological data for precipitation, evaporation and air temperature. A very precise grid in 1 x 1 degrees of longitude and latitude was created. The average estimated dew potential for the territory of Serbia is 20-40 mm.year(-1)for the south of the country, 15 mm.year(-1)for the north, 30-50 mm.year(-1)for the central region and 20-30 mm.year(-1)for the east. In most drought regions, it is  lt  10 mm.year(-1).m(-2). Counties with the largest dew capacity (between 15,200 and 20,000 L) include Borski, Nisavski and Jablanicki in the eastern part of the country, as well as Zlatiborski, Raski and Pec in the western and southern parts, respectively. On the other hand, counties with the lowest dew capacity (2,000-3,000 L) encompass northern parts of Serbia (Sremski, Severno-Banatski, Srednje-Banatski, Juzno-Banatski, Severno-Backi and Zapadno-Backi). The possibility for dew use is particularly strong during the spring. The estimated total capacity of the dew potential for Serbia is 1.5 x 10(7)L. By comparing the obtained data for Serbia, it is concluded that the amount of this type of water resource is not large, but enough for use in agricultural and other economic sectors.

AB  - Using the existing knowledge about the social and cultural characteristics of the Roma in Serbia, possible connection between Roma population and preserving of natural resources was established. This analysis acquired in social and other related studies, as well as the data obtained through the GIS (geographical information system) methodology, was used for determining the spatial distribution of Roma settlements and activities of the Roma community in the space. The Toplica District has one of the high percentages of Roma population and their daily migrations. This article investigates the possibility to raise the level of their economic activity and social integration, while simultaneously preserving natural resources and improving environmental safety. With the specific GIS, and numerical and sociology analysis, we try to address main problems in the District, hoping to find a connection between inner migration of Roma and better preservation of nature.

AB  - In the last decades. knowledge about the climate has increased significantly. Climate change today is the subject of many sciences, including meteorology, climatology, geology, geography, geophysics, astronomy, etc. The present predictions with updated meteorological data and with data of the number of particles of CO2 in the troposphere may give satisfying results. Forecasting for industrial grains such as maize, soybean, and wheat will be essential for industry and everyday life. Within the last agreement of climate change in Paris, global temperatures will continuously be increasing by 2100. In this research, we used a synthetic grid with agroclimatological data which comprises predictions until 2100. These data were found in the sub-section called World Clim Version 1 or in the CMIP5 database. After numerical and gcospatial GIS analysis, we got the following predictions: (i) slight- no temperature changes or changes including the increase of temperature by 0.5 degrees C, (ii) moderate- temperature increases by 2.0 degrees C, (iii) severe- temperature increases by 5.0 degrees C, and (iv) incredible-temperature increases to extreme values. incase of which the survival of plants will be endangered.

AB  - The study is focused on diatom communities as indicators of the water quality of aquatic ecosystems. The study included watercourses of the Timok River Basin in eastern Serbia. Sampling of algological material and physicochemical measurements were conducted at 30 locations in September 2016. Non-metric multidimensional scaling (NMDS) showed that conductivity had an effect on the spatial variability of the diatom communities. At locations under influence of acid mine drainage along the Borska river, its tributaries and the Timok river, the diversity of benthic diatoms decreased and the abundance of metal tolerant taxa Achnanthidium minutissimum, Nitzschia capitellata and Nitzschia palea increased. Our study revealed that the combined effect of different pollutants significantly impacted on diatom assemblages; diatoms are good bioindicators of multiple pressures; and diatom indices with different types of pollution, may show an unreliable picture of the actual state, therefore, biological and physico-chemical parameters should also be observed when interpreting the results of a solely diatom-based assessment of the ecological condition of freshwaters.

AB  - Recent climate changes cause significant natural and socio-economic consequences. They represent one of the major environmental problems of the late 20th and early 21st centuries. Changes in temperature and precipitation play a significant role in understanding climate change issues. They include numerous extreme climatic events such as heat waves, droughts, forest fires and more. Looking at regional differences in temperature and precipitation regime change, Southern Europe, including the Republic of Serbia, occupies a special place. The Mačva district (3.272 km²) is almost four times as spacious as the Mačva area. The administrative-political division of the Mačva district is comprised of eight municipalities. The paper presents trends of two climate variables: mean annual air temperature and mean annual precipitation in the study area. In methodological sense, the main statistical procedure is the non-parametric Mann-Kendall (MK) test. Data from three available meteorological stations in the Mačva district (1949-2015) were used for the analysis. The presented results of the trends in air temperature indicate that there is a statistically significant positive trend in all-time series. In trends, precipitation amounts a statistically significant positive trend was observed in two time series, while in one there is no trend. The expressed trends, especially in the case of air temperatures, lead to the possibility of drought. Mačva district and Mačva have some agricultural importance in the Republic of Serbia. For these reasons, some adaptation to climate change is needed as arid conditions lead to fluctuations in agricultural yield.

AB  - This study aims to estimate geothermal potential, radioactivity levels, and environmental pollution of six most popular spas in Central Serbia (Ovcar, Gornja Trepca, Vrnjacka, Mataruska, Bogutovacka and Sokobanja), as well as to evaluate potential exposure and health risks for living and visiting population. Thermal possibilities of the studied spas showed medium and low geothermal potential with total thermal power of 0.025 MW. Gamma dose rates in air varied from 63 to 178 nSv h(-1). Specific activities of natural radionuclides (Ra-226, Th-232 and K-40) and Cs-137 in soil were measured; annual effective doses and excess lifetime cancer risk from radionuclides were calculated. Radon concentration in thermal-mineral waters from the spas ranged between 1.5 and 60.7 Bq L-1 (the highest values were measured in Sokobanja). The annual effective dose from radon due to water ingestion was calculated. The analyzed soils had a clay loam texture. The presence of As, Cr, Cu, Fe, Mn, Ni, Pb, Cd, Zn, and Hg in soil was investigated. The concentrations of As, Cr, Ni, and Hg exceeded the regulatory limits in many samples. Soil samples from Mataruska spa were generally the most contaminated with heavy metals, while the lowest heavy metal concentrations were observed in Sokobanja. Health effects of exposure to heavy metals in soil were estimated by non-carcinogenic risk and carcinogenic risk assessment. Total carcinogenic risk ranged between 6 x 10(-4) and 137 x 10(-4) for children and between 0.1 x 10(-4) and 2.2 x 10(-4) for adults. The sum of 16 PAHs analyzed in soil samples varied from 92 to 854 mu g kg(-1).

AB  - During the past twenty years, the need to reach the Moon by the private space missions has been growing. Some of the private missions are supported by Google Lunar X-prize and Space-X. In the period between 2020 and 2050 private companies will be planning landing to the Moon with their own capacity. These missions can send new geodesy and cartography data. Lunar topography modelling with new satellite and remote sensing data gives plenty of possibilities for its exploration. GIS (Geographical Information System) may be successfully to the Moon topography analysis. According to the results after GIS numerical analysis 30% of the territory of the Moon showed excellent characteristics for landing. The most useful parts of the Moon for potential landing belong to the altitude between 2,000 and 3,000 m and on the plateaus with the north-east direction of azimuth. These plateaus have an excellent inclination of 3 degrees and azimuth of 120 degrees. The main aim and goal of this investigation would be in better understanding of Moon topography and relief. With help of GIS numerical methods, the astronomical geodesy may be applied in better way. A potential mission to the Moon can use this topography investigation, presented maps and results.

AB  - In this paper, we are explaining a decade long investigation of historical, sacral and archaeological sites in the Toplica District (Serbia) as one of the significant cultural heritage sites in Europe with more than 226 objects with different time of origin. The survey was carried out for the purpose of better recognizing the archaeological potential. In science like archaeology, static objects, if not dynamized, remain unrecognizable to the general public, regardless of their historical and archaeological importance. Historical changes during the period of more than 7,000 years, with many sites of cultural heritage in this district, were recognized. Ordinary kriging was employed through Quantum Geographical Information System (QGIS) and System for Automated Geoscientific Analysis (SAGA). The positions of historical objects are registered, from the Neolithic period to modern times. With the help of GIS and geo-statistical methods, archaeological and historical layers can be rediscovered and better recognized. GIS algorithm ordinary kriging was used to complete the cultural heritage potential and archaeological valorization of the objects with geo-spatial dispersion. As a final product, we have obtained maps with historical and archaeological locations. For the first time, we used a scientific name for contour lines (archlines) with an equal number of archaeological units per density. In the end, archaeological and historical objects and their features were shown with the support of geographical and GIS methods.

AB  - This is the first research of this type which includes the wider area of Kosovo taking into account the mineral wealth. The concentrations of 20 elements: Al, As, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, P, Pb, Se, Si, V, and Zn were determined using ICP-OES. The ranges of concentrations of toxic elements are lead (Pb) 0.044-14.98 g/kg, arsenic (As) 0.007-0.33 g/kg, cadmium (Cd) 0.004-0.044 g/kg, and chromium (Cr) 0.053-0.245 g/kg. The spatial distribution of toxic elements was described using distribution maps. Principal component and cluster analyses were performed to reveal grouping of samples.
