A method for direct electrothermal at. absorption spectrometric detn. of lead in wine is described. A mixed chem. modifier contg. 20 mg of tungsten as ammonium paratungstate and 4 mg palladium as palladium chloride is applied to thermally stabilize Pb in w ...
Shift multiplexing is a holographic storage method implemented with spherical wave reference beams. We present the main properties of shift multiplexing, compare it with angle multiplexing, and describe the design of a holographic 3D disk system that is ca ...

A flexible motif search technique is presented which has two major components: (1) a generalized profile syntax serving as a motif definition languaje; and (2) a motif search method specifically adapted to the problem of finding multiple instances of a mot ...
A new method called selective inversion soft COSY (SIS-COSY) is described. By using this method the coupling between active and passive spins can be detected. The pulse sequence consists of 3 semiselective 270 Deg pulses, which gives a spectrum consisting ...
PROSITE is a compilation of sites and patterns found in protein sequences; it can be used as a method of determining the function of uncharacterized proteins translated from genomic or cDNA sequences. ...
Five arom. 1,4-diketones I [R = 2,4,6-(MeO)3, H, 4-Me, 4-MeO, 2,4-(MeO)2] were prepd. using succinyl chloride as acylating reagent. Arom. 1,4-diketone I [R = 2,4,6-(MeO)3] was also prepd. by using succinic anhydride as acylating reagent. The first method c ...
ABSTRACT The aim of the present paper is 10 investigate two types of SSR countermeasures: a) Phase shifters used to modulate the generator real power b) Static VAR compensator (SVC) and its auxiliary controllers. An eigenvalue analysis method is used to st ...
We have developed a simple and accurate isocratic HPLC method, without any prederivatisation, for the determination of glucose, lactate, glutamine, glutamate, pyrrolidone carboxylic acid and alanine in samples from mammalian cell cultures. The method has b ...
A new mathematical approach for the influence of mobile positive ions on the current-voltage characteristics of MOS structures is presented. This new method gives formulations which are more applicable than those described in the literature. Examples of th ...
The detn. of glycerol in aq. allergenic products is accomplished by gas chromatog. using a column packed with Chromosorb 101 and FID. Quantitation is performed using the internal std. technique. The method is accurate to within 1% and has proved to be supe ...
