TOXIC METALS IN SOIL SAMPLES NEAR SOURCE OF POLLUTION WITH ECOLOGICAL RISK IN NORTHERN KOSOVO AND METOHIJA
The term toxic metals means heavy and light metals. Higher toxicity of heavy metals compared to light ones was stated, while many light metals belong to physiological and oligo-elements. The term heavy metals means metals ... -
A transmission length limit for space division multiplexing in step-index silica optical fibers
(Taylor & Francis, 2019-08-28)By solving the power flow equation, we investigate the influence of mode coupling on space division multiplexing capability of three multimode step-index silica optical fibres with a different strengths of mode coupling. ... -
Transmission performance of multimode W- type microstructured polymer optical fibers
(Optica Publishing Group (Formerly OSA), 2022-06-23)By solving the time-independent power flow equation (TI PFE), we study mode coupling in a multimode W-type microstructured polymer optical fiber (mPOF) with a solid-core. The multimode W-type mPOF is created by modifying ... -
Two Interval Upper-Bound Q-Function Approximations with Applications
(Mathematics and computer sciences, 2022-10-10)The Gaussian Q-function has considerable applications in numerous areas of science and engineering. However, the fact that a closed-form expression for this function does not exist encourages finding approximations or ... -
USE OF GEOGEBRA IN THE STUDY OF ROTATIONS
(Western Serbia Academy of Applied Studies, Užice (Serbia), 2021-10-08)With the development of information technologies and educational software, there was a need for research and examination of how and in what way to use them in teaching, without losing the quality of existing traditional ... -
Uticaj razlicitih doza y-zračenja na hidrolitičku stabilnost modifikovanih urea-formaldehidnih (UF) smola
(Srpsko hemijsko drustvo, 2018-05-30)Zbog emisije formaldehida (CH2O) iz drvenih proizvoda, gde se urea- formaldehidne (UF) smole, izmedu ostalog, koriste za impregnaciju drvenih panela koje se koriste u unutrašnjosti stambenih i drugih objekata pozeljno ... -

VISUALIZATION OF GEOMETRIC OBJECTS USING PROGRAM PACKAGE MATHEMATICA
In geometry teaching, visualization is an indispensable method of work. Its importance is emphasized in the study of abstract theories when the human mind is not capable enough to perceive the regularities determined by ... -
The vulcanization properties of hybrid elastomeric materials based on waste rubber powder
(University of Belgrade, Technical Faculty in Bor, 2019-06-18)Elastomeric materials have viscoelastic properties and can be designed for numerous applications, tires production, vibration isolation and damping. These properties can be tailored for a wide temperature range and in ... -
Wavelength dependence of equilibrium mode distribution and steady state distribution in W-type plastic-clad silica fibers
(Elsevier, 2019-11-27)Wavelength dependence of equilibrium mode distribution (EMD) and steady state distribution (SSD) in W-type plastic-clad silica fibers (PCSFs) is investigated in this paper for parametrically varied width of the fiber’s ... -
Wavelength dependent transmission in W-type plastic optical fibers with graded index core distribution
(Elsevier, 2021-08-08)This paper investigates the wavelength dependence of the equilibrium mode distribution (EMD) and steady state distribution (SSD) in W-type plastic optical fibers (POFs) with graded index (GI) core distribution for ... -
Zero search method for complex oscillating equation directly by direction
The problem of location of the zero solution of the second order complex oscillator equation for the given analytic function is unlikely to be completely solved. Therefore, estimates have long been resorted to. The easiest ... -
