The pressurized pipelines: The risk of bidirectional fluid exchange with the environment / Cevovodi pod pritiskom i rizik od razmene fluida sa okolinom
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2009)
The pressurized pipeline fluid transport is supposed to be cheap, reliable and efficient. If buried, pipelines are hard observable by means of leaks, minor cracks and asset damages. These phenomena can influence both the ...
Experimental testing of certain thermo-physical and mechanical properties of EPS concrete / Eksperimentalna ispitivanja određenih termo-fizičkih i mehaničkih svojstava EPS betona
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2009)
In this paper the experimental results obtained during testing of certain important properties of EPS concrete as a type of lightweight composite material - regarding Civil engineering physics are presented. Most of the ...
Uporedna analiza rezultata dobijenih primenom ortogonalnih i neortogonalnih mreža u modelima prostornog tečenja – deo l / Comparative Analysis of the Results Obtained with 3D Orthogonal And Non-Orthogonal Grids in the 3D-Flow Models – Part 1
(Srpsko društvo za odvodnjavanje i navodnjavanje, 2006)
Razmatra se primena ortogonalnih i neortogonalnih mreža u modelima prostornog tečenja. Za analizu je izabrano rečno ušće, jer je na ušću tečenje izrazito prostorno, a korito ima složen oblik. Na kvalitet rezultata dobijenih ...
Coefficient characterization for certain classes of univalent functions
(Bulletin of the Belgian Mathematical Society - Simon Stevin, 2009)
Necessary and sufficient coefficient conditions are established for certain
classes of analytic functions to be univalent in the unit disk. In addition,
characterizations and convolution results are established for these ...
The influence of type and quantity of polypropylene fibers on mechanical properties of mortar and concrete / Uticaj vrste i količine polipropilenskih vlakana na mehanička svojstva kompozita tipa maltera i betona
(Savez inženjera metalurgije Srbije, Beograd, 2002)
Reinforcement of different brittle materials using fibers in order to improve their mechanical properties is an age-old concept. This concept is especially actual in the last two decades, when a large number of new fiber ...
Common right factor of skew polynomials / The Resultants of Non-Commutative Polynomials
(Matematički vesnik, 2008)
Let R = K[x; σ] be a skew polynomial ring over a division ring K. Necessary and sufficient condition under which common right factor of two skew polynomials exists is estab-lished. It is shown that the existence of common ...

Ecologically guarantied discharge downstream from the hydropower plants / Garantovani protoci nizvodno od hidroelektrana
(JP Elektroprivreda Srbije, Beograd, 2007)
One of the very important decisions in planning a hydropower plant is to determine ecologically guarantied discharge that should be released from reservoir or downstream of the intake structures of derivation systems. On ...
Water distribution system reliability illustrated by the case study of the RWS Dubovac-Zrenjanin-Kikinda / Pouzdanost složenih vodovodnih sistema na primeru RVS Dubovac-Zrenjanin-Kikinda
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2007)
Water supply networks have a specific feature that makes them more complicated then many other water management systems. Namely, to make sure that the system performs well, apart from the mechanical characteristics of the ...
Dyed microspheres for quantification of UV dose distributions: Photochemical reactor characterization by Lagrangian actinomety
(Journal of Environmental Engineering. ASCE / American Society of Civil Engineers, 2006)
Lagrangian actinometry represents a new method of photochemical reactor characterization. The method is based on an
application of dyed microspheres, which were developed by attachment of E-5- 2-methoxycarbonylethenyl ...
