The assessment of aridity in Leskovac Basin, Serbia (1981-2010)
(2018-08-25)
In the paper, the aridity is defined on the basis of four climate indices: De Martonne's index of aridity, Lang’s Rain Factor and Gračanin’s Rain factor for the vegetation period and hydrothermal coefficient of Seljaninov. ...
Neodrživost prakse urbanističkog planiranja u Srbiji – primer izmena i dopuna planova generalne regulacije.
(Asocijacija prostornih planera Srbije, Univerzitet u Beogradu – Geografski fakultet, 2018-04-10)
Srbija nakon 2000. godine, urbzano prolazi kroz proces post-socijalističke transformacije. Ovaj proces prati transformacija socijalističke privrede, odlikovane snažnom regulatornom ulogom države, ka kapitalističkoj privredi, ...
A stochastic model for estimation of repair rate for system operating under performance based logistics
(Polish Maintanace Society, 2018-09-01)
Performance Based Logistics (PBL) concept has an aim to improve the system availability and it has been extensively researched in the recent years. These researches showed that inventory level does not impact system ...
Determination of glass transition temperature and irradiation resistance of elastomeric materials based on chlorinated natural rubber
(RAD Association, 2018-06-18)
Synthetic rubbers have different surface structures but benefit from chlorination. In many cases their tensile strength and extensibility is lower than natural rubber and for that reason more easily mechanically damaged. ...
Effect of silica on the properties of elastomeric materials based on NR/BR/SBR ternary rubber blend
(University of Banja Luka, Faculty of Technology, Banja Luka, 2018-11-02)
The effects of pyrogeneous silica on the mechanical properties of elastomeric
materials based on natural rubber (NR), polybutadiene rubber (PB) and styrene butadiene
rubber (SBR) are reported. For sample preparations the ...

STRUKTURIRANJE EKOLOSKI PRIHVATLJIVIH ELASTOMERNIH KOMPOZITNIH MATERIJALA
(Univerzitet u Kragujevcu, Agronomski fakultet u Čačku, 2018-03-09)
Kod recikliranja otpadne gume neophodno je poznavati hemijski sastav
otpadnog proizvoda, ukoliko će se on koristiti u recepturama za nove hibridne
elastomerne materijale. Kompozitni elastomerni materijali dobijeni od ...
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 ...
