Water quality control has become extremely important from industrial and environmental view points. Flow injection analysis (FIA) has been increasingly recognized as a valuable tool for such a monitoring system.1 However, some problems exist when FIA is used for a monitoring process. The most important problem is the consumption of large amounts of reagents and carrier solutions during continuo...

The design and performance of an easily constructed spectroelectrochemical cell suitable for batch and flow injection measurements are described. The cell is fabricated from a commercially available 5-mm quartz cuvette and employs 60 ppi reticulated vitreous carbon as the working electrode, resulting in a reasonable compromise between optical sensitivity and thin-layer electrochemical behavior....

Eye tracking is becoming widely used in HCI and many other fields to study user behaviour. Eye tracking data explains user attention pattern in great details and is often large in volume. This complex nature makes analyzing it a challenge. Various visualizations have been designed to aid the data analysis, but none of them focuses sequential patterns in eye gaze, which can reveal insights in us...

Analyser injection systems based on the principle of flow-injection analysis depend on the technique used. They generally take the form of an injection loop valve; the injected sample volume is determined by the volume of the valve. Injection systems are seldom designed with a time factor to define this volume. The authors report on an original injection system, which enables the two techniques...

This paper describes a fully automated pre-injection analysis technique aimed at reducing the cost of fault injection campaigns. The technique optimizes the fault-space by utilizing assembly-level knowledge of the target system in order to place single bit-flips in registers and memory locations only immediately before these are read by the executed instructions. This way, faults (time-location...

sperm chromatin integrity has been being recognized as an important factor in male fertility. during normal fertilization, high quality sperm with intact chromatin are selected through natural selection in journey from vagina to fallopian tube. however, using assisted reproductive techniques, particularly icsi, the natural selection is bypassed. therefore sperm with dna breakage have the opport...

A flow injection method for the quantitative analysis of vancomycin hydrochloride, C66H75Cl2N9O24.HCl (HVCM), based on the reaction with copper (II) ions, is presented. HVCM forms a lilac-blue complex with copper ions at pH≅4.5 in aqueous solutions, with maximum absorption at 555 nm. The detection limit was estimated to be about 8.5×10-5 mol L-1; the quantitation limit is about 2.5×10-4 mol L-1...
