Solids flow pattern in gas-flowing solids-fixed bed contactors. Part II Mathematical modeling
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
In this paper a mathematical model for solids flow in gas-flowing solids-fixed bed contactors is developed. The presented four-parameter model assumes plug flow with axial dispersion in the dynamic, fast moving solids zone ...
Static holdup in Gas - Flowing solids - Fixed bed contactors
(Elsevier Science Bv, Amsterdam, 2009)
Static holdup was investigated experimentally and theoretically in gas - flowing solids - fixed bed bench-scale contactors. Diverse packing elements were used: Raschig rings, ceramic beads, crushed stone and glass beads. ...
Antifungal efficiency of corona pretreated polyester and polyamide fabrics loaded with Ag nanoparticles
(Springer, New York, 2009)
This study discusses the possibility of using the corona (electric discharge at atmospheric pressure) treatment for fiber surface activation that can facilitate the loading of Ag nanoparticles (NPs) from colloids onto the ...
Design of the Switching Controller for the High-Capacity Non-Blocking Internet Router
(IEEE-Inst Electrical Electronics Engineers Inc, Piscataway, 2009)
The sequential greedy scheduling (SGS) algorithm is a scalable maximal matching algorithm. This algorithm was conceptually proposed and well received since it provides non-blocking in an Internet router with input buffers ...
Non-isothermal crystallization of k2o center dot tio2 center dot 3geo(2) glass
(Springer, Dordrecht, 2009)
The crystallization of K2O center dot TiO2 center dot 3GeO(2) glass under non-isothermal condition was studied. In powdered glass with particle sizes less than 0.15 mm, surface crystallization was dominant and an activation ...
Dielectric investigation of some woven fabrics
(Amer Inst Physics, Melville, 2009)
In this paper, we have investigated the temperature dependence of dielectric properties (relative dielectric permeabilities and dielectric tangents of losses) for woven fabrics of hemp, jute, flax, cotton, polyester (PES), ...
Application of temperature and pH responsive microhydrogels for functional finishing of cotton fabric
(Taylor & Francis Ltd, Abingdon, 2009)
This paper discusses the developing of an innovative strategy for functional finishing of cotton by application of surface modifying systems based on stimuli responsive microparticulate hydrogels. Dual responsive hydrogels ...
Biocompatible and bioactive nanostructured glass coatings synthesized by pulsed laser deposition: In vitro biological tests
(Elsevier, Amsterdam, 2009)
We report on the synthesis by pulsed laser deposition with a KrF* excimer laser source (lambda = 248 nm, tau = 25 ns) of bioglass thin films of 6P57 and 6P61 types. Physiology, viability, and proliferation of human osteoblast ...
Influence of microstructure and phase composition on the nanoindentation characterization of bioceramic materials based on hydroxyapatite
(Elsevier Sci Ltd, Oxford, 2009)
The aim of the study was to investigate the influence of microstructure and phase composition on the mechanical behaviour of hydroxyapatite (HAp) and biphasic HAp/beta-tricalcium phosphate (beta-TCP) bioceramic materials ...
Sol-Gel Combustion Synthesis of La-9.33(SiO4)(6)O-2 Oxyapatite
(Taylor & Francis Inc, Philadelphia, 2009)
Synthesis of La-9.33(SiO4)(6)O-2 was performed by a new method that represents the combination of sol-gel and combustion procedures using glycine as the fuel. Syntheses were performed from ethanol-water solutions of oxides ...
