Influence of increased temperature on clay fast drying process
(Revista Romana de Materiale/ Romanian Journal of Materials, 2009)
In this paper are presented testing results during process of fast drying at conditions of increased temperature. Three different masonry raw materials were examined using recircular laboratory dryer with air recirculation. ...
Electrodeposited hydroxyapatite thin films modified by ion beam irradiation
(Natl Inst Optoelectronics, Bucharest-Magurele, 2009)
Surface modification of hydroxyapatite (HA) thin films electrodeposited on titanium was conducted by ion implantation, using nitrogen and argon ions at different constant fluences of 1x10(15), 1x10(16) and 1x10(17) ions/cm(2). ...
Acceptability of Residual Stresses Measurement Methods of Butt Weldments and Repairs
(Strojarstvo, 2009)
The joints made by fusion of materials are exposed to the influence of residual stresses induced by welding thermal cycles. Residual stresses were measured on butt welded plates made of NIOMOL 490K, before and after ...
An empirical equation for temperature and pressure dependence of liquid heat capacity
(Elsevier, Amsterdam, 2009)
A new empirical equation for liquid heat capacity calculation, as a function of temperature and pressure is recommended. This four-parameter equation was tested and compared to the four-parameter equation developed by ...
Recycled wool-based nonwoven material for decolorisation of dyehouse effluents
(Emerald Group Publishing Limited, Bingley, 2009)
Purpose - The purpose of this paper is to investigate the possible application of recycled wool-based nonwoven material (RWNM) for removal of different dyes that are used in textile dye houses. Design/methodology/approach ...
Solvent Effects on the Structure-Activity Relationship of Phenytoin-like Anticonvulsant Drugs
(Springer/Plenum Publishers, New York, 2009)
The absorption spectra of nine compounds structurally related to phenytoin (5,5-diphenylhydantoin) were recorded in twelve solvents over the range of 200 to 400 nm. The effects of solvent dipolarity/polarizability and ...
The irritative property of α-tricalcium phosphate to the rabbit skin
(General Physiol And Biophysics, Bratislava, 2009)
The aim of this study was to assess the irritant properties of a new developed calcium phosphate ceramic, α-tricalcium phosphate (α-TCP) after single application to intact skin of the rabbit. The test substance, α-TCP was ...
Immobilization of modified penicillin G acylase on Sepabeads carriers
(Versita, Warsaw, 2009)
An approach to stable covalent immobilization of chemically modified penicillin G acylase from Escherichia coli on Sepabeads(R) carriers with high retention of hydrolytic activity and thermal stability is presented. The ...
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 ...
Citrate-based zinc-polyaniline secondary cell: part I: optimization of the citrate/chloride electrolyte
(Springer, Dordrecht, 2009)
Electrochemical behavior of zinc and thin polyaniline (PANI) electrodes in citrate/chloride-contained electrolyte has been investigated by the means of electrolyte composition optimization. Electrolyte contained 0.8 M ...
