We use the maximally-localized Wannier function method to study bonding properties in amorphous silicon. This study represents, to our knowledge, the first application of the Wannier-function analysis to a disordered system. Our results show that, in the p ...
The use of remotely sensed near-surface soil moisture for the estimation of evaporation is investigated. Two widely used parameterizations of evaporation, the so-called alpha and beta methods, which use near-surface soil moisture to reduce some measure of ...
The paper presents a new method for the automatic monitoring of bridges deformations. Based on the use of electronic high precision inclinometers, this method permits to accurately reconstruct the deflected shape of the bridge and to follow its long-term e ...

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 ...
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 ...
New variants are presented of the selectively inverted soft correlation NMR spectroscopy using multiple-frequency decoupling. Tests were made using the std. Me trans-2-phenylcyclopropanecarboxylate. This method can det. arbitrary coupling consts. with grea ...
The Allyloxycarbonyl (Alloc) moiety can be removed smoothly and selectively in good yield (73-100%) from allylic eaters, carbamates and carbonates by aqueous Pd (0) catalyzed allyl transfer to diethylamine in aqueous media employing a water soluble phosphi ...
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 ...
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 ...
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 ...
