The paper presents results of a long-term investigations of tritium activity concentrations in precipitation and radiocesium activity concentrations in ground level air in Belgrade, Serbia. Samples were collected at three ...

A high-resolution separator for the SPIRAL2/DESIR project at GANIL has been designed. The extracted isotopes from SPIRAL2 will be transported to and cooled in a RFQ cooler yielding beams with very low transverse emittance ...

Simplicial complexes represent useful and accurate models of complex networks and complex systems in general. We explore the properties of spectra of combinatorial Laplacian operator of simplicial complexes and show its ...

The model of photoassisted oxygen ordering assumes that the enhancement of the conducting properties of RBa2Cu3O6+x material during the light illumination, is the consequence of the CuOx plane oxygen atoms reordering into ...

In this article, it is shown that Riemanns zeta function zeta(s) admits two limit representations when R(s) GT 1. Each of these limit representations is deduced by using simple arguments based upon the classical Tannerys ...

Air pollution mitigation is a necessity in Serbia, due to its high levels of criteria pollutants in ambient environment. Successful implementation of mitigation measures requires access to sufficient information from ...

The nano-sized copper tungstate (CuWO4) was prepared by precipitation method in the presence of non-ionic copolymer surfactant (polyoxyethylene-polyoxypropylene block copolymer) and consequent annealing at low temperature ...

The carbon/carbon (C/C) composite with satisfactory mechanical properties were obtained through introduction of partially carbonized fibers as a precursor. Applying this procedure the production cost of C/C composites may ...

The molecular relaxation behaviour of isotactic polypropylene (iPP) exposed to gamma radiation in air to various absorbed doses (up to 700 kGy) has been investigated by dielectric loss (tan delta) analysis; the polar (mainly ...
