Diatoms of the Dojkinci River (Nature Park „Stara Planina“, Serbia)
(Croatian Botanical Society, 2014)
The Dojkinci River belongs to the Nature Park „Stara planina“, Eastern Serbia. The river has never been investigated by algologists. Diatom samples were collected during July 2010 on 15 localities from different types of ...
Influence of chemical stress on sulfur-polymer composite structure
(Nova Science Publishers, Inc., 2014)
Sulfur- polymer composites are high performance thermoplastic materials made of mineral aggregate, filler, and modified sulfur binder, instead of cement and water as in ordinary Portland cement- based composites at ...
Implementation of image analysis research on concrete lifetime prediction for thermal stability and cavitaion eriosion testing
(Nova Science Publishers, Inc., 2014)
Lifetime prediction for construction material is essential and very often crucial for
determination of impact on material application and service. Many models based on
different parameters were used to monitor materials ...
Image analysis technique for evaluating damage evolution and predicting mechanical strength of concrete structures under corrosion conditions
(Nova Science Publishers, Inc., 2014)
The degradation of concrete structures, which progresses as time passes, is caused by
external factors such as chemical, physical and mechanical interferences. In the case of
chemical deterioration, various ions penetrate ...
Entropy change of open thermodynamic systems in self-organizing processes
(Society of Thermal Engineers of Serbia, 2014)
The thermodynamic models available in the literature predict that during self-organizing processes the entropy of a cell considered as an open thermodynamic system
decreases. This prediction leads to conclusion that cell ...
Phase equilibrium data for the hydrogen sulphide + methane system at temperatures from 186 to 313 K and pressures up to about 14 MPa
(Elsevier, 2014)
Isothermal vapour–liquid equilibrium data have been measured for the methane–hydrogen sulphide (CH4 + H2S) binary system at five temperatures from 186.25 to 313.08 K, and pressures between 0.043 and 13.182 MPa. The ...
Comparative study of entropy and information change in closed and open thermodynamic systems
(Elsevier, 2014)
In this paper we discuss the entropy and information aspects of closed and open systems. The information and entropy change of the system are discussed in the context of RNA synthesis.
Postupak hlađenja istopljenog sumpora modifikovanog diciklopentadienom na ravnoj metalnoj podlozi / Procedure for cooling molten sulphur modified by dicyclopentadiene on a flat metal surface
(Zavod za intelektualnu svojinu Republike Srbije, 2014)
Zbog svojih karakteristika sumporni beton, sumpor-modifikovani asfalt i sumporni malter se sve više koriste u svetu kao građevinski materijali. Jedna od osnovnih komponenti za njihovo donbijanje je sumpor nastao u procesu ...
Grafičko određivanje eksponenta politrope u karakterističnim dijagramima / Graphical determination of polytropic index in characteristic diagrams
(Academy of Sciences and Arts of the Republic of Srpska, 2014)
U ovom radu, koristeći postojeća znanja iz termodinamike, prikazana su tri načina grafičkog određivanja eksponenta politrope, kao i klasični analitički način.U radu smo koristili karakteristične dijagrame p-v i T-s i u ...
