Abstract: An extensible nonwoven fabric, and method for its manufacture, on which the source, medicinal component, pattern and/or other pieces of information are recognizable at the beginning of and during fabric use. It is made mainly of highly crimped fibers, with a compressed region where no fibers are melted and bonded together, with a tensile strength of 25 N/5-cm-width or more in both the machine direction and the cross direction. It may be manufactured by causing a water jet having a pressure of 5 MPa or more to act onto a web made mainly of a latent crimpable fiber, forming an entangled fiber web, causing heat to act on it, crimping the fiber converting it to a highly crimped fiber while contracting the web's area by 30% or more forming a contracted fiber web, and embossing it such that the fibers are not melted and bonded together.

Abstract: Provided is a biological nitrogen removal method which includes, causing to flow a support having, on the surface portion thereof, a two-layered microbial film which holes, in the outer layer, nitrite type nitrifying bacteria or aerobic bacteria and nitrite type nitrifying bacteria as a dominant species and, in the inner layer, anaerobic ammonia oxidizing bacteria as a dominant species while being surrounded with the nitrite type nitrifying bacteria; and thereby carrying out denitrification of the water to be treated by making use of the anaerobic ammonia oxidation reaction. In the biological nitrogen removal method, a feed rate of the support (total surface area of the support per unit capacity of the reaction tank) is adjusted so that an amount of nitrous acid produced by the nitrite type nitrification reaction through the action of the nitrite type nitrifying bacteria reaches a level to inhibit a nitrate type nitrification reaction.

Abstract: The present invention provides a method by which, novel G protein-coupled receptor (GPCR) genes or GPCR proteins which could discover the biocommunication system or identify novel target proteins for medicine can be searched for cyclopaedically on a data base. The method comprises the steps of: extracting open reading frames (ORFs) comprising 250 to 1000 amino acid residues from the human genome data; eliminating ORFs derived from repeated sequences of DNA, ORFs with substantial undetermined amino acids, and ORFs in which any single amino acid residue comprising more than 20% of the whole sequence; extracting ORFs having 6 to 8 transmembrane segments using SOSUI; and searching the obtained ORFs for genes homologous to known GPCR genes, preferably, genes wherein their highest homologous genes in homology search are GPCR genes or GPCR associated genes.

Abstract: Each of the washing units A and B comprises an openable and closable pinch valve unit 4 branchwise connected to a pipeline C, an autofeeder unit 5 for controlling the feed for advance and retraction movement of a high pressure hose 6 having rotatable nozzle unit connected to the front end thereof, and a hose reel unit 7 for winding and unwinding the high pressure hose. During washing operation, the nozzle unit enters the pipeline C through the pinch valve unit 4 now opened to wash the inner surface of the pipeline. During nonwashing period, the nozzle unit is moved rearward and completely isolated from the pipeline by the pinch valve unit 4 now closed. Therefore, the washing units A and B are completely separated from the pipeline C during nonwashing period.
