Enumeration of labelled quasi-initially connected digraphs
(Elsevier, 2000)
A new class of connected digraphs is introduced - the class of quasi-initially connected digraphs. They are enumerated in the labelled case. Using the apparatus developed for labelled quasi-initially connected digraphs ...
Thermal investigations of CoAPO materials prepared by using piperidine as a structure-directing agent
(Elsevier, Amsterdam, 2000)
Two CoAPO materials (CoAPO-34 and CoAPO-20) with relatively high Co2+/Al3+ substitution level were synthesised in either fluoride-free or fluoride-containing reaction mixture using piperidine as a structure-directing agent. ...
An intensity based optical fiber sensor for low velocity impact detection in unidirectional composites
(Taylor & Francis Ltd, Abingdon, 2000)
Prevention df serious damage of composite structures might be achieved by inspecting the structural integrity during exploitation. This paper decribes the design and development of a promising optical fiber sensor system ...
Immobilization/encapsulation of cells using electrostatic droplet generation - Experiments and theory
(Minerva Biotecnologica, 2000)
The mechanism of alginate droplet formation as well as experimental parameters for producing very small polymer microbeads (i,e, less then 100 microns diameter) using an electrostatic droplet generator were investigated, ...
Study of chlorination of nickel ferrite by gaseous chlorine and calcium chloride in the presence of active additives
(Wiley, Hoboken, 2000)
Thermodynamic analysis and experimental research of the chlorination of nickel ferrite (NiFe2O4) by gaseous chlorine in the presence of added C, BaS, S and NaCl in the temperature range from 300 to 900 degrees C are given ...
A new approach to the velocity field investigation in case of the entry flow in curved pipes with circular cross section
(Springer Wien, Wien, 2000)
In this paper an analysis of a laminar flow in a bend preceded by the straight section is presented. The flow is supposed to be unperturbed far upstream, while far downstream it becomes fully developed. In the vicinity of ...
The effect of low-temperature plasma pretreatment on wool printing
(Amer Assoc Textile Chemists Colorists-Aatcc, Res Triangle Pk, 2000)
The application of radio-frequency capacitively coupled plasma for the treatment of wool was studied. The influence of plasma parameters on the printing and mechanical properties of wool was determined. Results after plasma ...
Modulation of the mechanical properties of tissue engineered cartilage
(IOS Press, Amsterdam, 2000)
Cartilaginous constructs have been grown in vitro using chondrocytes, biodegradable polymer scaffolds, and tissue culture bioreactors. In the present work, we studied how the composition and mechanical properties of ...
Detecting aniline in air in systems based on piezoelectric quartz crystal resonators modified with poly(ethylene glycol succinate) under static and dynamic conditions
(Journal of Analytical Chemistry, 2000)
The optimal conditions have been found for aniline sorption on a film of poly(ethylene glycol succinate) by the piezoelectric quartz crystal microbalance method using bulk acoustic wave sensors based on AT-cut quartz ...
Thermal investigation of two FePO materials prepared in the presence of 1,2-diaminoethane
(Elsevier, Amsterdam, 2000)
Two porous iron phosphates were synthesized hydrothermaly from a reaction mixture of FeCl3:H3PO4:1,2-diaminoethane:H2O in the molar ratio 1:3:5:70. The chemical formulas indicate difference only in water content; however, ...
