Photoreactive hyperbranched urethane acrylates modified with a branched saturated fatty acid
(Elsevier, Amsterdam, 2006)
Urethane acrylate resins based on partially modified aliphatic hyperbranched polyesters (HBP) were synthesized. HBP of the second and the third pseudo-generation were synthesized from 2,2-bis(hydroxymethyl)propionic acid ...
Fitness-for-purpose assessment of repaired feedwater heater / Ocena podobnosti za upotrebu zagrejača napojne vode posle popravke
(Society for Structural Integrity and Life, Institute for Material Testing, 2006)
The leakage of tube-tubesheet joint of feedwater heater on the inlet required redesign and repair by additional tube welding. The original design took into account only the sealing, and subsequently after some period leakage ...

(Natl Inst Science Communication, New Delhi, 2006)
Lipase from Candida rugosa has been used to Study the influence of 3-alkyl-2,4-pentanedione and N-alkyl cyanoacetamide Structure on the enzyme catalyzed reaction of pyridone ring formation in water at 40 degrees C. Starting ...
Comparative studies of chloride and chloride/citrate based electrolytes for zinc-polyaniline batteries
(Pergamon-Elsevier Science Ltd, Oxford, 2006)
Electrochemical behavior of zinc and thin polyaniline (PANI) polymerized from 0.1 M HCl to 0.1 M aniline on graphite electrode, in 0.2 M ZnCl(2) and 0.50 M NH(4)Cl (chloride electrolyte) and with addition of 0.33 M Na-citrate ...
Nanoindentation of in situ polymers in hydroxyapatite/poly-L-lactide biocomposites
(Trans Tech Publications Ltd, Durnten-Zurich, 2006)
In order to obtain more accurate properties after compaction of hydroxyapatite (HAp)/poly-L-lactide (PLLA) composite, high-resolution measurement of mechanical properties method is proposed to determine the properties of ...
Solvent and substituent effect on electronic spectra of N-(4-substituted phenyl)-2,3-diphenylpropanamides
(Arkivoc, 2006)
The UV absorption spectra (200-400 nm) of eleven N-(4-substituted phenyl)-2,3-diphenyl-propanamides 1 have been recorded in fourteen solvents of different polarity. A simple Hammett equation was used to study the effects ...
Fast estimation of quasi-steady states of cyclic nonlinear processes based on higher-order frequency response functions. Case study: Cyclic operation of an adsorption column
(Amer Chemical Soc, Washington, 2006)
A new method for fast approximate calculation of quasi-steady states of cyclic processes is presented. The method is based on the concept of higher-order frequency response functions. The system input is represented in the ...
Synthesis of N-and N,N-dialkyl-S-alkylthiolcarbamates by the rearrangement of N-and N,N-dialkyl-O-thioncarbamates / Sinteza N- i N,N-dialkil-S-alkiltiol-karbamata premeštanjem N- i N,N-dialkil-O-alkiltionkarbamata
(Association of Chemical Engineers of Serbia, 2006)
A series of N- and N,N-dialkyl-S-alkylthiolcarbamates were synthesized by the rearrangement of N- and N,N-dialkyl-O-alkylthioncarbamates in the presence of diethyl sulfate. The synthesis of some compounds without catalyst ...
A new threshold voltage analytical model of strained Si/SiGe MOSFET
