In this paper, we present an approach based on the simultaneous use of multilevel monitoring systems for the ground and surface water and wavelet-based analysis of the time series observed to detect the main mechanisms influencing the water level, electrical conductivity (EC) and temperature (T) in ground and surface water of the river Neretva coastal aquifer system. Although the area of interest is under significant impact of seawater intrusion, the presented approach enabled the insight to transient response of the system to external loadings like precipitation and irrigation system primarily. The capacity of the monitoring system has been demonstrated on two different subareas, respectively, Diga and Jasenska. While the Diga area is shown to be under significant influence of the seawater, the Jasenska area shows sensitivity to precipitation and pumping station (PS) Modric operative regime. Groundwater parameters as observed during dry periods at Jasenska show the presence of stratification. Wavelet-based analysis enabled the determination of the interdependence of the variables of interest as well as their temporal dependence. Determined regimes of the surface water, as found within the Jasenska channel, are additionally supported by the in situ profiling results, thus strengthening the findings of the study. Our findings reflect the capacity of the approach to capture for the stratification of the groundwater parameters induced by seawater intrusion and external loadings.
Rad donosi pregled nedavnih protekcionističkih mjera Sjedinjenih Američkih Država (SAD) prema Kini te daje uvid u dvogodišnji trgovinski rat između te dvije države. Analiziraju se postupci i posljedice na svjetsko gospodarstvo. Osim direktnih posljedica na Kinu i SAD, promatra se i neizravan utjecaj na druge zemlje. Promatra se svjetski trend nametanja trgovinskih mjera, njihove prednosti i nedostatci te etičke nedoumice povezane s međunarodnom trgovinskom razmjenom.
Taking into account that the available capacities of human and material resources are key for a stable and sustainable health system of a country, this paper deals with the relation between the macroeconomic environment and the movement of the number of employees in the health system in the case of the Republic of Serbia. The aim of this paper is to make recommendations for further research based on the conducted analyses and to review the existing trends critically, in order to raise the level of public awareness in efforts to reduce the outflow of professional staff. The available official data of the institutions of the health system of the Republic of Serbia were used in the research, and time series from 2010 to 2018 were included.
Exposing children to environmental pollutants during periods significant for their physiological development can lead to long-lasting health effects, dysfunction, and disease. The aim of this paper was to focus on a relatively scarce ambient AQ monitoring practice at the locations of preschol and school institutions in Serbia, within the local network of AQ monitoring stations. This was a cross-sectional study covering period 2015 to 2020. Measuring points (SO2, NO2, soot, PM10) were in front of kindergardens, primary and secondary schools in urban settlements. Results originate from the continuous public health programme conducted by the Institute of Public Health of Serbia. Only PM10 and B(a)P values at some points have exceeded annual limit values in front of chosen facilities in 2020. In sum, both the absolute number of urban ambient AQ measuring points monitored by the local network of Institutes of Public Health and those in front of the educational facilities have increased in this period: from 73/17 to 172/26. In a percentual view, these facilities are chosen more seldom within this time frame, dropping from 23.29 to 15.12% of all AQ monitoring points. As such facilities are mainly located at important city intersections, in order to assess the exposure to air pollution of vulnerable population groups (children from preschool to adolescence age), there is a need to locate measuring points near them.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
