a simple ion imprinted amino-functionalized sorbent was synthesized by coupling activated carbon with iminodiacetic acid, a functional compound for metal chelating, through cyanoric chloride spacer. the resulting sorbent has been characterized using fourier transform infrared spectroscopy (ft-ir), elemental analysis, thermogravimetric analysis (tga) and evaluated for the preconcentration and de...

An analog-to-digital converter for on-chip focal-plane image sensor applications. The analog-to-digital converter utilizes a single charge integrating amplifier in a charge balancing architecture to implement successive approximation analog-to-digital conversion. This design requires minimal chip area and has high speed and low power dissipation for operation in the 2-10 bit range. The inventio...

An antithrombin III deficient infant presented with iliac vein thrombosis, apparently precipitated by an overtight nappy. Venous thrombosis is unusual, both in normal and in antithrombin III deficient children, but children with venous thrombosis should have their natural anticoagulants assayed and obvious risk factors avoided.

The analysis of Sudan dyes has gained considerable attention during last years. In several publications multiple peaks in chromatograms of Sudan III and Sudan IV have been detected. It is demonstrated in this work that if the sample is kept in darkness before analysis, only one chromatographic peak appears for Sudan III or Sudan IV. In normal lighting conditions two peaks are observed. This lig...

The present invention is embodied in a charge coupled device (CCD)/charge injection device (CID) architecture capable of performing a Fourier transform by simultaneous matrix vector multiplication (MVM) operations in respective plural CCDICID arrays in parallel in 0(1) steps. For example, in one embodiment, a first CCDICID array stores charge packets representing a first matrix operator based u...

objective(s) the sst-i polymorphic site on the 3' untranslated region of the apo ciii gene, has been previously reported to be associated with hypertriglyceridemia. the aim of the present study was to explore the association between sst-i polymorphism with plasma lipid and lipoprotein levels in hyperlipidemic (hlp) patients from semnan province, iran. materials and methods genomic dna was ...
