Analysis and improvement of production transmitters in IHTM / Analiza i unapređenje proizvodnje transmitera u IHTM-u
(Tehnika - Mašinstvo, 2009)
In this paper analyzes the technology of production of these IHTM transmitters in relation to the other side of competition. QFD analysis gives us the direction to be moving production of local transmitters. Foreign ...
Rapid pyrolysis of Serbian soft brown coals
(VINCA Institute of Nuclear Sciences, 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 ...
Adsorption-Desorption Noise in Plasmonic Chemical/Biological Sensors in Multiple Analyte Environment
(Smart Sensors, Actuators, and Mems Iv, 2009)
We analyzed the intrinsic noise of plasmonic sensors caused by the adsorption-desorption of gaseous analytes on the sensor surface. We analyzed a general situation when there is a larger number of different species in the ...
CO2 looping cycles with CaO-based sorbent pretreated in CO2 at high temperature
(Chemical Engineering Science, 2009)
In this study, pretreatment of CaO-based sorbent in a CO2 atmosphere at high temperature is investigated for its effect on CO2 capture. Three limestones from three widely different geographical locations are used for the ...
Freshwater cyanobacterial blooms and primary liver cancer epidemiological studies in Serbia
(Journal of Environmental Science and Health - Part C Environmental Carcinogenesis and Ecotoxicology, 2009)
A large part of Central Serbia experiences continual shortage of sufficient ground water resources. For that reason, more than 20 reservoirs serve as drinking water suppliers. Significant and persistent cyanobacterial ...
Planar chromatography of cholic acid-derived cis-trans isomeric bis-steroidal tetraoxanes
(Journal of Planar Chromatography - Modern TLC, 2009)
Seven pairs of cis-trans isomers of bis-steroidal tetraoxanes have been examined by both normal-phase (NP) and reversed-phase (RP) planar chromatography. Unmodified silica gel was used with ethyl acetate-toluene and ethyl ...
The state of nickel in the silver modified NiMg/SiO2 vegetable oil hydrogenation catalysts
(Maik Nauka/Interperiodica/Springer, New York, 2009)
Two series of silver modified Ni-Mg materials were synthesized by precipitation-deposition on SiO2 support derived from two silica sources: diatomite activated at 800°C (Series a; Mg/Ni = 0.1 and SiO 2/Ni = 1.07) and ...
Analysis of design and installation thermocouples in power plants / Analiza izrade i ugradnje termoparova u elektroenergetskim postrojenjima
(Tehnika - Mašinstvo, 2009)
Measurement of temperature, in addition to pressure, is the most common type of measurement in the process industry and power plants. Thermocouples are most common in contact with devices. The selection and quality of final ...
Two-layer adsorption and adsorbed mass fluctuations on micro/nanostructures
(Elsevier, 2009)
This paper presents for the first time the analysis of fluctuations of both the number of adsorbed particles and the adsorbed mass in the case of multilayer adsorption on the surface of MEMS/NEMS structures, described by ...
Fishnet-Based Metamaterials: Spectral Tuning Through Adsorption Mechanism
(Polish Academy of Sciences, 2009)
In this work we consider the tuning of spectral reflectance of fishnet metamaterials with circular or elliptic apertures due to the presence of dielectric analyte adsorbed within the pores of the dielectric part. We simulated ...
