A process for detecting the presence or absence of a specific nucleic acid sequence or antibody in a sample using an oligonucleotide to bind to the nucleic acid sequence or antibody to be detected, forming double-stranded nucleic acid sequence using the bound oligonucleotide in conjunction with another oligonucleotide or DNA synthesis, synthesizing RNA transcripts from the thus-formed double-stran...

A multiple base addition sequencing scheme (BASS) for the rapid sequencing of oligonucleotides (DNA and RNA) involving the steps of attaching a plurality of DNA or RNA strands to be sequenced to a coated support, adding a modified nucleotide, detecting the modified nucleotide, removing the blocking group and repeating the steps until the RNA or DNA is sequenced. Methods for improving and monitorin...

The invention relates to a method for monitoring and controlling the data flow in a packet data net or a datagram net comprising lines and nodes, the lines via nodes connecting by the network comprised terminals between which traffic takes place in the form of data packets or datagram. Every line and every node comprises a process preceded by a certain queue of data packets/datagram. Data packets ...

Disclosed here are synergistic combinations of 2-(Thiocyanomethylthio)benzothiazole and hexahydro-1,3,5-tris(2-hydroxyethyl)-s-triazine for use in controlling the growth of at least one microorganism, such as fungi and bacteria, in aqueous fluids, such as metalworking fluids. Methods of controlling the growth of at least one microorganism are also disclosed.

The object of the invention is a method for manufacturing a laminating reinforced fibre structure (1), in which fibre layers (7, 8) made of cross-woven warp or weft yarn bundles are manufactured as a warp structure, these being tied together with ties (9) and a filler (4) is placed in the channel formed by the layers one top of each other and the ties. In accordance with the invention two fiber la...

Congestion in a high speed connection oriented packet network carrying bursty data and real time service is avoided by a novel in-call negotiation scheme for reserving bandwidth for real time calls and reserving buffer capacity for bursty calls. For a real time call, a centralized call controller in each switch in the network determines which of its outgoing trunks has available to it the peak ban...

Reactive congestion control in an asynchronous transfer mode (ATM) network where the network is formed by the interconnection of nodes each including a forward path (8-OF, 8-2F, 8-(C)F) for transfer of information from source (4-(S)) to destination (4-(D)) through the network and a return path (8-(C)R, 8-(C-1)R, 8-1R, 8-OR) for returning congestion control signals. Each source includes a modifiabl...

A process and apparatus for the treatment of pre-concentrated solid-liquid mixture streams, and in particular the dewatering of solid-liquid mixture streams metering the mixture from an intermediate container to a liquid separation device. The process accounts for variable inlet conditions or parameters of the solid-liquid mixture stream which is supplied to the intermediate container. A preset me...

A method for the production of a self stabilized composition of dipeptide sweeteners useful in cooking and baking applications yields dipeptide granules of substantially uniform spherical shape that fall within a narrow particle size distribution range.
