Production of sorbents based on immobilized zeolite in alginate/PVA beads for sorption of copper ions from water solutions
(Elsevier Science Bv, Amsterdam, 2012)
The mechanism and kinetics of the tungsten (vi)-oxide reduction in the vertical tube reactor
(Editura Stiintifica Fmr, Bucharest, 2011)
Presented study shows the analysis of the process of reduction of WO(3) powder with hydrogen in the vertical tube reactor, representing a new approach in comparison to the conventional methods in the horizontal tube reactor. ...
Microeconomics of the materials and energents consumption in a simulated copper casting process
(Edimet SpA, 2012)
An analytical model for the optimization of the consumption of materials and energents in a typical copper casting process based on a standard simulation procedure is presented. The proposed microeconomic analysis in ...
Technological possibilities and justification of electro-contact rapairing
(Technics Technologies Education Management, 2011)
This paper presents a selected repair technology for different types of electro-contacts by replacing the contact plates on the brass body of the electro-contacts and connecting the elements by process of brazing with ...
Microstructure and cavitation behaviour of alloyed austempered ductile irons
(Taylor & Francis Ltd, Abingdon, 2018)
In this paper, the study of cavitation behaviour of austempered ductile iron (ADI) alloyed with copper, as well as copper and nickel with a fully ausferritic microstructure, is presented. The ADI materials used were ...
Experimental Design Optimization of the Determination of Total Halogens in Coal by Combustion-Ion Chromatography
(Taylor & Francis Inc, Philadelphia, 2015)
Determination of total halogens in coal was investigated with oxygen bomb combustion followed by ion chromatography. Experimental parameters were optimized by fractional factorial design and response surface methodology. ...
Thermal properties of poly(urethane-ester-siloxane)s based on hyperbranched polyester
(Maik Nauka/Interperiodica/Springer, New York, 2011)
Novel polyurethanes (PUs) were synthesized using hydroxy-terminated hyperbranched polyester (BH-20) and 4,4'-methylenediphenyl diisocyanate (MDI) as hard segments and hydroxy-terminated ethylene oxide-poly(dimethylsiloxa ...
Mixed-ligand Mn-II and Cu-II complexes with alternating 2,2 '-bipyrimidine and terephthalate bridges
(International Union of Crystallography, 2015)
The novel polymeric complexes catena-poly[[diaquamanganese(II)]-mu-2,2'-bipyrimidine-kappa N-4(1),N-1':N-3,N-3'-[diaquamanganese(II)]-bis(mu-terephthalato-kappa O-2(1):O-4)], [Mn-2(C8H4O4)(2)(C8H6N4)(H2O)(4)](n), (I), and ...
Functional fermented whey carrot beverage - qualitative, nutritive and techno-economic analysis
(Ars Docendi, Bucharest, 2018)
The main objectives of the paper were to investigate the possibility of use of carrot juice in the production of functional fermented whey based beverage, to simulate and economically evaluate the production process and ...
Stress Degradation Studies on Zolpidem Tartrate Using LC-DAD and LC-MS Methods
(Akademiai Kiado Zrt, Budapest, 2014)
The present study was designed to characterize the possible degradation products of zolpidem tartrate under various stress conditions according to International Conference on Harmonization (ICH) guidelines Q1A(R2). After ...
