A preliminary evaluation of a simple (bare) quartz tube trap for collection of SbH3 and for volatilization of trapped analyte with subsequent atomization in a multiple microflame quartz tube atomizer (multiatomizer) for atomic absorption spectrometry is presented. The influence of relevant experimental parameters on the collection/volatilization efficiency was investigated. The parameters studied Were: collection temperature and time, volatilization temperature and flow rates of air and hydrogen for the volatilization. Under optimized conditions, the collection/volatilization efficiency was 65%. For the collection time of 120 s (sample volume of 8 ml), the detection limit was 3.9 pg ml(-1), and the analytical plot was linear up to 1.25 ng ml(-1). Possible ways of improving the performance of the set-up as well as the collection/volatilization efficiency are suggested.


Near real-time estimation of ionosphere vertical total electron content from GNSS satellites using B-splines in a Kalman filter

Abstract. Although the number of terrestrial global navigation satellite system (GNSS) receivers supported by the International GNSS Service (IGS) is rapidly growing, the worldwide rather inhomogeneously distributed observation sites do not allow the generation of high-resolution global ionosphere products. Conversely, with the regionally enormous increase in highly precise GNSS data, the demands on (near) real-time ionosphere products, necessary in many applications such as navigation, are growing very fas...

Ozden, N; Akaltan, F; Suzer, S; Akovali, G (Elsevier BV, 1999-12-01)
Statement of problem. Adhesion and cohesion have important roles in denture retention, and attempts have been made to improve the wettability of the acrylic resin material by surface treatments.

This paper considers the job (lot) scheduling problem for two-stage flow shops in which the movement of transfer batches (sublots) from the first stage to the next are allowed. Set-up, processing and removal times are considered as separable and independent of the order in which jobs are processed at any of two stages. An optimal transfer batch sizing and scheduling algorithm which has an objective of minimizing the maximum flow time (makespan) is developed and demonstrated by a numerical example.
Amphoteric Surface Hydrogels from Hydrogen-Bonded Multilayers: Reversible Protein Uptake
Kharlampieva, Eugenia; Erel Göktepe, İrem; Sukhishvili, Svetlana (2006-10-08)
INTRODUCTION. The aim of producing bioactive materials motivated the use of hydrogels as materials which control binding, absorption and release of proteins1,2. Advantages of using multilayering to produce surface hydrogels include the applicability of the technique to virtually any substrate type, and the possibility to control the film thickness by a simple variation of the number of layers. In our study, we report on one-component hydrogels derived from hydrogen-bonded multilayers which show pH-dependent...
