Ternary NR/BR/SBR rubber blend nanocomposites
(SAGE, 2018-02-24)
The goal of this work was to synthesize and characterize ternary rubber blends based on polyisoprene (natural rubber (NR)), polybutadiene rubber (BR), and styrene–butadiene rubber (SBR) (NR/BR/SBR = 25/25/50) reinforced ...
Enhancement of the bandwidth of W-type glass optical fibers in the infrared wavelength region
(Elsevier, 2018-08-28)
Transmission characteristics (bandwidth and steady state loss) of multimode W-type glass optical fibers are investigated by solving the time-dependent power flow equation. Results show how the bandwidth in W-type glass ...
Calculation of the bandwidth of W-type photonic crystal fibers by time-dependent power flow equation
(Elsevier, 2018-06-30)
A multimode photonic crystal fiber with a solid-core takes the characteristic W-shaped index profile upon forming
an inner cladding layer with its own value of the effective refractive index corresponding to the distinct ...
Infrared wavelength dependence of leaky mode losses and steady state distribution in W-type glass optical fibers
(Elsevier, 2018-03-13)
Infrared wavelength dependence of leaky mode losses and steady state distribution
(SSD) in W-type glass optical fibers (doubly clad fibers with three layers) is
investigated in this paper for parametrically varied ...
Environmental risk assessment of radioactivity and heavy metals in soil of Toplica region, South Serbia
(Springer, 2018-03-13)
Activity levels of natural and artificial radionuclides and content of ten heavy metals (As, Cd,
Co, Cr, Cu, Mn, Ni, Pb, Zn and Hg) were investigated in 41 soil samples collected from Toplica region located in the south ...
Environmental radioactivity with respect to geology of some Serbian spas
(Springer, 2018-05-17)
This study was performed in order to investigate gamma dose rates, radon exhalation rates and soil radioactivity with respect to geology. Fifteen locations in three Serbian spas were under investigation. Gamma dose rate ...
Application of software packages for demonstration of physics experiments
(2018-10-07)
Veliki broj osnovnih i srednjih škola u Republici Srbiji nije adekvatno opremeljen za izvođenje nastave fizike. Tu se pre svega misli na nedovoljnu opremljenost kabineta za nastavu fizike, kojima često nedostaje oprema za ...

Sistemska merenja koncentracije radona senajčešće izvode na slučajnim uzorcima stambenih objekata.
Influence of mode coupling on three, four and five spatially multiplexed channels in multimode step-index plastic optical fibers
(Elsevier, 2018-04-04)
We investigate the influence of mode coupling on space division multiplexing capability of three multimode step-index plastic optical fibers with different strengths of mode coupling. Results show that mode
coupling ...
