Rapid pyrolysis of Serbian soft brown coals
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2009)
Soft brown coals of the open coal fields of Kolubara and Kostolac are the main domestic energy sources of Serbia. This paper presents the results of investigations on rapid devolatilization of these two coals which have ...
Modelling of dynamic interaction between structure and trolley for mega container cranes
(Taylor & Francis Inc, Philadelphia, 2009)
This article deals with the analysis of trolley impact on the dynamic behaviour of the flexible structure of the mega quayside container crane (QCC) boom, identified as the most relevant structural part. It develops a ...
Microstructure Changes of Nickel-Base Superalloys Induced by Interaction with Femtosecond Laser Beam
(Polish Acad Sciences Inst Physics, Warsaw, 2009)
The investigation was performed on nickel-base superalloys, with nickel being the most influential alloying ingredient. After thermo-mechanical preparation and corresponding processing, femtosecond laser beam machining has ...
Experimental determination of airflow resistance coefficient of porous plates for fly ash air-slide pneumatic transport
(Assoc Textile Engineers Technicians Croatia, Zagreb, 2009)
Different porous materials are Used for the transport of discharged fly ash from electrostatic precipitator in air-slide pueumatic conveying system The knowledge of physical, mechanical as well as flow properties of these ...
Micromechanical estimates of the critical values of j-integral for the steel of steam pipelines
(Springer, New York, 2009)
We analyze the level of damage to 14MoV63 steel for steam pipelines under the conditions of crack-growth initiation according to the mechanism of ductile fracture. The state of the material after service for about 100,000 ...
Transition temperature and fracture mode of as-castand austempered ductile iron
(Wiley, Hoboken, 2008)
The ductile to brittle transition temperature is a very important criterion that is used for selection of materials in some applications, especially in low-temperature conditions. For that reason, in this paper transition ...
HELIO code prediction of hydrogen accumulation in non-vented steam pipelines
(Elsevier Science Sa, Lausanne, 2006)
The thermal-hydraulic and physico-chemical code HELIO is developed for numerical simulations and analyses of radiolytic gases (hydrogen and oxygen) accumulation in non-vented steam pipelines of nuclear power plant systems. ...
Ash from thermal power plants as secondary raw material
(Arhiv za Higijenu Rada i Toksikologiju, 2007)
The basic characteristic of thermal power plants in the Republic of Serbia is that they use low-grade brown coal (lignite) as a fuel. Depending on the location of coal mines, lignite may have different properties such as ...
Temperature and radiation hardness of polycarbonate capacitors
(National Institute of Optoelectronics, 2007)
The aim of this paper is to examine the influence of temperature raising, as well as neutron and gamma irradiation on the dissipation factor (loss tangent, tg delta) and capacitance (C) of capacitors with polycarbonate ...
Wear behaviour of ti6al4v alloy against al2o3 under linear reciprocating sliding
(Journal of the Balkan Tribological Association, 2011)
Tribological behaviour of four different heat-treated Ti6Al4V alloys, during linear reciprocating sliding against alumina, on the microscale was investigated. Experiments were carried out for dry sliding and in the Ringer ...
