  • GEOTHERMAL ENERGY RESOURCE POTENTIAL IN NIGERIA FROM AEROMAGNETIC REVIEWS:
           ANOTHER PANACEA FOR ENERGY CRISES AND ENVIRONMENTAL GLOBAL WARMING

    • Authors: Levi Ikechukwu Nwankwo
      Pages: 001 - 009
      Abstract: An effort has been made in this paper to advocate a panacea to the prevailing energy crisis in Nigeria by reviewing the country’s geothermal energy resource potential from regional aeromagnetic calculations. There is widespread occurrence of warm/hot springs in Nigeria, which gives credence to the availability and abundance of geothermal reserves. Results of aeromagnetic investigations also confirm that areas with anomalous high heat flow exist in Nigeria, showing high prospects of employing geothermal energy for direct and indirect energy applications. It is, therefore, imperative for Nigeria to take a quantum leap in holistic renewable energy research and development through appropriate government science advice, policy and environmental management.

      Pages: 011 - 025
      Abstract: Drinking water quality has a direct impact on the health of the population and is the main indicator of environmental sanitation and hygienic living conditions. The aim of this study was to investigate the quality of drinking water from three water supply systems in Serbia.The retrospective descriptive study was done covering the period between 2011 and 2015. We collected data from control water supply systems in three towns and tested the samples as required by the Regulation on the Hygienic Acceptability of Potable Water. The following indicators of water security were analyzed: ammonia, nitrates, nitrites, consumption of potassium permanganate, organic matter content, pH and electroconductivity. The microbiological quality was determined by analyzing the indicators of fecal contamination, Escherichia coli, Enterococci and Salmonellae, using the membrane filtration method.The most frequent parameters of physical-chemical insecurity of water were a high concentration of ammonia, lower pH levels, and increased consumption of potassium permanganate. The most common detected microbes were aerobic mesophilic bacteria which are not significant from the aspect of human health.These results showed that drinking water could pose a potential risk to local consumers.

  • POSSIBILITY OF ORGANIC WASTE INCLUSION AND IMPLEMENTATION IN A CLOSED-LOOP
           SYSTEM

    • Authors: Ana Momčilović, Gordana Stefanović, Predrag Rajković, Biljana Milutinović, Dragiša Savić
      Pages: 027 - 037
      Abstract: Organic waste represents a challenging type of waste for implementation in the flows of a circular economy.  The main idea of the paper is the assessment of the inclusion possibility of different types of organic waste generated in one area into the flows of the circular economy. For this purpose, a mathematical model was developed and applied. Based on the mathematical model, the optimum mixing ratio of the several organic waste fractions, which will be subjected to the anaerobic digestion treatment and composting, is determined. Developed scenarios are based on the organic waste types and quantities available in the considered area. In each of the scenarios, process products, in the form of biogas and compost, are introduced into the flows of the circular economy. Based on the inputs and outputs in developed scenarios, the efficiency of the circular economy for each scenario is determined.

  • WORKER SAFETY DURING EXCAVATION AND TRENCHING CONSTRUCTION WORK

    • Authors: Jasmina Radosavljević, Ana Vukadinović, Amelija Đorđević
      Pages: 039 - 047
      Abstract: Earthworks are the integral part of any construction work in civil engineering and building construction. The construction activities performed during earthworks include the following: excavation, earthmoving, earth transport, and earth compaction. During earthworks, the excavation site is subject to harmful, flammable, or hazardous materials, damage to underground installations, the collapse of the earth, and many more risks. Therefore, construction work for trenching and excavation requires the implementation of adequate safety measures. This paper discusses the safety measures for workers during earthworks that involve excavations up to and exceeding one meter in depth.

  • ANALYSIS OF RISK AND NO-RISK INTERVENTIONS BY MEMBERS OF FIRE AND RESCUE
           UNITS UNDER MULTI-RISK CONDITIONS

    • Authors: Marijola Božović, Emina Mihajlović, Nenad Živković, Snežana Živković
      Pages: 049 - 060
      Abstract: The issue of occupational safety and health of the members of fire and rescue units has been continuously studied by numerous authors. Their interest stems from the constant need to improve the methods and procedures of occupational safety and health assessments for fire and rescue unit members, all for the purpose of preventing injuries, primarily the fatal ones. The fact that a certain number of high-risk situations in which firefighters avoid an injury or death remain unreported poses a serious threat to the firefighters’ safety. This threat has been unjustifiably neglected and it is what motivated the research discussed in this paper, which reveals the results of three discriminant analyses.

  • THE IMPORTANCE OF COMMUNICATION IN AN EMERGENCY

    • Authors: Sandra Đukić, Nataša Novaković, Snežana Živković
      Pages: 061 - 068
      Abstract: Communication, regardless of type, is an important part of the life and work of each individual. In addition, it is important for further growth and development for both the individual and the entire organization.During communication, there are often errors in the transfer of information, so it is necessary to work continuously to improve the quality of information. Also, important differences in communication can be noted when there is a change from regular to emergency situations. Responsible and empowered persons must ensure that communication is at a satisfactory level in order to eliminate the consequences, reduce material damage, human casualties and prevent further development of disasters.
