The application of benthic diatoms in waterquality assessment (Mlava River, Serbia)
(University of Zagreb, 2016)
The main objective of this study was to assess the ecological status of the Mlava River based on
epilithic diatoms and to test the use of diatom indices as a tool for estimating the quality of fl owing waters in
Serbia. ...
Diatoms from a peat bog on the Pešter plateau (southwestern Serbia): New records for diatom flora of Serbia
(Institut za Bioloska Istrazivanja, 2015)
The distribution of diatoms was studied in three types of diatom communities (epiphytes, benthos and plankton)
of a peat bog on the Pešter plateau. The observed diatom flora inhabited all investigated communities, comprising ...
An updated list of Serbian diatom flora – new recorded taxa
(Serbian Biological Society, 2018)
Diatoms are a widespread group of organisms with well-known ecological preferences. Knowledge of their diversity is of great importance for assessing the environmental status of different aquatic ecosystems. The present ...
Polianilinski tanki filmovi u senzorima za detekciju štetnih agenasa kod zavarivanja / Polyaniline thin films in sensors for detection of toxic welding vapors
(Belgrade: Association of the Chemical Engineers of Serbia, 2010)
In this paper the possibilities of applying sensors based on filters with surface acoustic waves (SAW) for the detection of harmful products in welding processes are analyzed. This review discusses the sensing mechanism ...
Analiza praga oštećenja bakra i aluminijuma u interakciji sa rubinskim laserom / The analysis of damage threshold in ruby laser interaction with copper and aluminium
(Association of Chemical Engineers of Serbia, 2010)
U radu su prikazani rezultati delovanja laserske svetlosti, talasne dužine λ = 694,3 nm (rubinski laser, Q-switch mod), na uzorke od bakra i aluminijuma. Cilj ispitivanja je bio da se odrede maksimalne gustine energije ...
System with Variable Energy, Volume and Number of Particles: Evaluation of Partition Function and Thermodynamic Quantities
(Pleiades Publishing, 2011)
Partition function and thermodynamic parameters of the system open with respect to energy E,
volume V and number of particles N, whereas temperature T, chemical potential μ and pressure P were kept
constant, were considered ...
Uticaj gama zračenja na molekulsku masu i staklasti prelaz PLLA / The Structure and Glass Transition Behaviour of PLLA under the Influence of Gamma Radiation
(Association of Chemical Engineers of Serbia, 2010)
U ovom radu ispitivan je uticaj gama zračenja na molekulsku masu i staklasti prelaz poli-L-laktida (PLLA). S obzirom da je PLLA pri izlaganju visokoenergijskom zračenju sklon kidanju lanaca i velikoj degradaciji, promene ...
The influence of the heat-treatment regime on a fracture surface of Nickel-based supperalloys / Vpliv toplotne obdelave na površino preloma superzlitin na osnovi niklja
(Inštitut za kovinske materiale in tehnologije, 2012)
Nickel-based superalloys are distinguished from other materials by their excellent mechanical and physical properties. As they are used at high temperatures and pressures, as well as in aggressive environments, their ...
Equation of state in form which relates mol fraction and molarity of two (or more) component thermodynamic system consisted of ideal gases, and it's applications.
(Society of Thermal Engineers of Serbia, 2010)
Most people would face a problem if there is a need to calculate the mole fraction of a substance A in a gaseous solution (a thermodynamic system containing two or more ideal gases) knowing its molarity at a given temperature ...
There are two twin shadows, but Einstein is one!
(Society of Thermal Engineers of Serbia, 2012)
2011 is the international year of chemistry, and it is exactly 100 years past after the P. Langevin promotion of “twin paradox” problem. The hundred year old problem still demands its solution. Twin paradox, established ...
