Statistical analysis of water quality parameters in the basin of the Nisava River (Serbia) in the period 2009-2018

This paper analyzes water quality from four hydrological stations in the Nisava river basin from 2009-2018 based on the following parameters: pH, conductivity, O-2 saturation, BOD5, suspended solids, total oxidized nitrogen, phosphates, turbidity and coliform bacteria. Authors have applied WQI (water quality index) as the most reliable indicator of the watercourses pollution for setting of surface water flow quality. Statistical analysis of variance (ANOVA) using t-test inferential statistical analysis and post-hoc Tukey test were applied to evaluate statistically significant differences between specific data groups. The results show that bad water quality was registered on all the profiles on an annual basis (WQI = 65-71). The river water pH decreases downstream, while values of BOD5, suspended solids, turbidity, TON, phosphates and coliform bacteria gradually increase. The waters of the Nisava at the station Nis belong to the third class of waters and they are mostly loaded with organic matter originating from waste sewage and industrial waters of both urban and rural areas

Statistical analysis of temperature regime change on the example of Sokobanja basin in eastern Serbia

The changes and oscillations in air temperature during the second half of the 20th and in the early 21st century, have become one of the major concerns of almost all scientific disciplines. Such changes are noticeable both at the local and global level. The objective of this paper is to point out that the changes of this climate element can also be detected at the local level. The research underlying this paper is, in terms of territory, limited to the Sokobanja basin in Eastern Serbia. The analysis relies on the data on air temperature for the period 1946-2012 taken from the Meteorological weather station located in Sokobanja. The obtained data were processed in line with the recommendations of the World Meteorological Organization. The evidenced statistically significant changes in air temperature were examined using the following statistical tests: Pettit test, Standard Normal Homogeneity test, Buishand range test, and von Neumann test

Application of Landsat-derived NDVI in monitoring and assessment of vegetation cover changes in Central Serbia

This paper evaluates the application of the Normalised Difference Vegetation Index (NDVI) in the monitoring and assessment of temporal vegetation cover changes (from 2006 to 2014) in three municipalities of Central Serbia: Topola, Jagodina and Kuršumlija. Additionally, special focus is placed on the analysis of the forest areas and the possible use of NDVI in the forest management sector. Results of the NDVI applied through Idrisi software identify all vegetation cover types and their typical values for presented case studies and observed periods. Obtained results for Serbian case studies indicate two major observations outlined for the investigated period. It was noticed that vegetation cover is experiencing a certain decrease, and that certain discrepancies exists between the NDVI and official forest area statistics for certain municipalities. The study outlines the positive outcomes of the applied remote sensing techniques, especially for southern Serbian municipalities where illegal logging activities are pronounced. Hence, this method proved very promising for countries performing national forest inventories, such as Serbia, providing local forest managers with several essential up-to-date information about vegetation cover changes on an annual basis. © 2019 Carpathian Journal of Earth and Environmental Sciences

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

Socio-geografska obeležja opštine Sokobanja

The Municipality of Sokobanja is situated in the central part of Eastern Serbia. In terms of its foregoing socio-geographic development, it is a specific geographic area. Its specific nature and characteristics are reflected in the steady depopulation indicted by a constant decrease of the population rate, the reduced population growth, and the permanent demographic trend of population aging. The aim of this paper is to point out to the main characteristics of the socio-geographic development of this municipality in the second half of the 20th century and at the beginning of the 21st century.Opština Sokobanja se nalazi u centralnom delu istočne Srbije. Na osnovu dosadašnjeg društveno-geografskog razvoja predstavlja specifičan geoprostor. Specifičnosti se ogledaju u konstantnom smanjenju broja stanovnika, smanjenju prirodnog priraštaja i permanentnom procesu demografskog starenja populacije. Cilj rada je da ukaže na najbitnija obeležja socio-geografskog razvoja opštine tokom druge polovine XX veka i početkom XXI veka

Changes in the Household Structure during the Period 1961-2011 in Serbia: Example of Sokobanja Municipality

Serbia and the entire Southeastern Europe was affected by considerable demographic, political, and socioeconomic changes in the second half of the twentieth century. The changes in the population were shown as an insufficient birthrate as well as an intense emigration. Apart from these, certain drastic changes in the household structure occurred. This article examines the total changes in the household number on the territory of the Republic of Serbia, with the municipality of Sokobanja as a prominent example. Other aims of the research are the analysis of the household composition and economic characteristics of the households

Preliminary geochemical investigation of karst barre from eastern Serbia Sokobanja basin

Karst bare is a hydrogeological phenomenon which denotes a karst terrain of limited area completely surrounded by rocks of low permeability, i.e. whose lower part is enclosed and bordered by more or less impervious rocks impeding ground water flowing out of the karst area. Sokobanja basin is one of the first localities where this kind of karst was detected. This study represents a preliminary geochemical analysis of karst bare samples from this locality. Atomic absorption spectrometric analysis shows that the studied samples are composed predominantly of Ca and contain minor amounts of Mg, probably in form of carbonate minerals obtained by dissolving with mineral acids. There are no detailed geochemical data about karst barre from this or any other locality in the available literature to date
