Планирање – функција менаџмента пројекта минералне индустрије
Жељко Вучић (2024)Просторно планирање је комплексан мултидисциплинаран процес утврђивања оптималног распореда људи, добара и делатности на одређеној територији ради његове оптималне употребе. Циљ просторног планирања је распоредити и најбоље користити садржаје у простору што је неизводљиво без детаљних анализа потенцијалних, штетних агенаса на целокупно подручје и његово становнисштво. Утицај рударства на окружење вишеструко се повећао након увођења технологије површинске експлоатације минералних сировина, али и свеукупног лошег дејства на животну средину. Под појом животне средине подразумевамо природне и радом створене вредности у ...Жељко Вучић. Планирање – функција менаџмента пројекта минералне индустрије, 2024

Analiza uporednog praćenja temperature površine ohlađenih materijala pri njihovom zagrevanju do ambijentalne temperature
U datom eksperimentalnom radu su termografskim metodama ispitivane termofizičke karakteristike različitih materijala. Za ispitivanja su izabrani mesingani niovčić, ugalj i pelet, jer imaju različita termoizolaciona svojstava i različito stanje površine. Uzorci su najpre hlađeni, a zatim je njihovo zagrevanje na sobnoj temperaturi praćeno termalnom kamerom. U drugom delu eksperimenta, korišćena je impulsna termografija, a zagrevanje površine uzoraka vršeno je svetlosnom pobudom.Stevan Đenadić, Ljubiša Tomić, Vesna Damnjanović, Katarina Nestorović.

Karst groundwater quantity assessment and sustainability: the approach appropriate for river basin management plans
Veljko Marinović, Zoran Stevanović (2019)As a result of the fact that karstified rocks can accumulate large amounts of high-quality groundwater, karst aquifer is considered, throughout the world, one of the most important types of aquifers. Due to their high permeability, but also vulnerability to pollution, these precious groundwater resources need to be properly evaluated and protected. Taking into account heterogeneity and complexity of the karst environment, it is difficult to propose a uniform algorithm for managing karst groundwater, which causes the necessity to ...Upravljanje karstnim podzemnim vodama, Pritisci na kvantitet voda, Plan upravljanja vodnim resursima, Bosna i Hercegovina, SrbijaVeljko Marinović, Zoran Stevanović.
