The influence of the parameters of lost foam process on the quality of aluminum alloys castings / Uticaj parametara lost foam procesa na kvalitet odlivaka legura aluminijuma
(Association of Chemical Engineers of Serbia, 2010)
This paper presents the research results of application of Lost foam process for aluminum alloys castings of a simple geometry. The process characteristic is that patterns and gating of moulds, made of polymers, stay in ...
Determination of pesticides in surface and ground waters by liquid chromatography-electrospray-tandem mass spectrometry
(Elsevier, Amsterdam, 2010)
The sensitive multiresidual analytical method for simultaneous analysis of 14 most commonly used agricultural pesticides in Serbia was developed and optimized. The selected insecticides, fungicides and herbicides belong ...
Optimization Approach for Continuous Catalytic Regenerative Reformer Processes
(Amer Chemical Soc, Washington, 2010)
The new approach for simulation and optimization of a continuous catalytic regenerative (CCR) reformer process is proposed. Typical CCR reforming processes consist of three to four reactors with recycle. The reaction ...
Fast evaluation of periodic operation of a heterogeneous reactor based on nonlinear frequency response analysis
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
The concept of higher-order frequency response functions (FRFs), which is based on Volterra series representation of nonlineral systems, is used to analyse the time-average performance of a perfectly mixed reactor subject ...
Microstructural investigations of the simulated heat affected zone of the creep resistant steel P91
(Taylor & Francis Ltd, Abingdon, 2010)
The microstructural changes in the heat affected zone (HAZ) of 9% chromium ferritic steel for manufacturing fossil fired power plant components are investigated. The heat treatment region of 925 degrees C in HAZ was tested ...
Effects of Filler Content on Mechanical Properties of Macroporous Composites
(Vsp Bv, Leiden, 2010)
The mechanical properties of hydroxyapatite related macroporous biocomposites (MPBs) are influenced by a number of factors, such as the pore size, the filler content and the properties of the matrix and the inclusion. ...

(Društvo za sunčevu energiju "Srbija solar", Zrenjanin, 2010)
This work deals with the formation of the system of approximate linear differential equations of the first order for approximate determination of the electrical conductivity of the sulfur acid and kalium-hydroxide water ...
1-Butanol + hexylamine plus n-heptane at temperature range (288.15-323.15 K): Experimental density data, excess molar volumes determination and modeling with cubic EOS
(Elsevier Science Bv, Amsterdam, 2010)
Densities rho of the ternary system 1-butanol + hexylamine + n-heptane and binaries: 1-butanol + hexylamine and hexylamine + n-heptane within the temperature range (288.15-323.15K) and atmospheric pressure are reported. ...
High temporal and inter-individual variation detected in the human ileal microbiota
(Wiley, Hoboken, 2010)
P gt The diversity and temporal stability of the predominant bacteria in the human ileum was studied with the use of ileal effluent samples of seven individuals with Brooke ileostomies. The total number of bacteria within ...
Evaluating the microbial diversity of an in vitro model of the human large intestine by phylogenetic microarray analysis
(Microbiology Soc, London, 2010)
A high-density phylogenetic microarray targeting small subunit rRNA (SSU rRNA) sequences of over 1000 microbial phylotypes of the human gastrointestinal tract, the HITChip, was used to assess the impact of faecal inoculum ...
