Fmoc-phosphotyrosine Fmoc-Tyr(PO(OH)2)OH (I) is new. USE/ADVANTAGE - (I) is used for the prodn. (claimed) of O-phosphotyrosine-contg. peptides which are model substrates for tyrosine kinase and phosphatase determinations. (I) gives better selectivity, purity and yields of O-phosphotyrosine-contg. peptides by avoiding the introduction of a protected phosphate gp. as required in prior art methods. I...

The vector processing apparatus fetches vector operands designated by an instruction from a storage to an operand buffer in a vector processor. The vector processor reads out and processes the elements of the vector operands stored in the operand buffer. The vector processor controls fetching of the element to be next processed from the operand buffer in accordance with the operation result. Thus,...

The present invention relates to the saccharide derivates of protocatechualdehyde of formula (I), the method for preparing therof, and the use of said derivatives as an anti-inflammatory agent. wherein R<1> represents a hydrogen atom or a benzoyl group, and R<2> represents an alkyl group.

A method and apparatus are disclosed for assigning replacement rows and columns in a two-dimensional redundant array. The array has original rows (10) and columns (12) with an element, e.g. a storage cell, at each intersection, and the array also has a limited number of replacement rows (16, RBL) and columns (14, RWL). After detecting all defect elements (18), a determination is made which of the ...

Deuterated aromatic aldehydes of the formula: where Ar is substituted phenyl, and derivatives thereof represented by the formula: where Ar is substituted or unsubstituted phenyl, and X1 and X2 are substituted hetero atoms or together with the carbon to which they are attached form a heterocycle. These compounds are useful as anticancer agents.

In a semiconductor memory device with normal word lines and spare word lines, a partial decoder (PD1 - PD4) receives and decodes a predetermined two of the bit signals of the original logic levels of an address signal, and two of the bit signals of the complementary logic levels, which correspond to the predetermined two bit signals, and outputs different signal combinations of the predetermined t...

A process for preparing lactulose from lactose in which an aqueous lactose mixture is reached with a sodium aluminate solution and the solution obtained is continuously neutralized by feeding this solution and a sulphuric acid solution to a reactor simultaneously in such a manner as to obtain a pH of between 4.5 and 8. By operating in this manner an aluminium hydroxide suspension is obtained which...
