Abstract: A method of determining or predicting a value P.sub.x of a property of a material X, which is a feed to a process or a property of a product of a process from said material or yield of said process, which method comprises measuring the absorption D.sub.i x of said material at more than one wavelength in the region 600-2600 nm, comparing the said absorptions or a derivative thereof with absorptions D.sub.i m or derivatives thereof at the same wavelength for a number of standards S in a bank for which said property or yield P is known, and choosing from the bank at least one standard S.sub.m with property P.sub.m said standard having the smallest average value of the absolute difference at each wavelength i between the absorption D.sub.i x (or derivative thereof) for the material and the absorption D.sub.i m (or derivative thereof) for the standard S.sub.m to obtain P.sub.x, with averaging of said properties or yields P.sub.m when more than one standard S.sub.

Abstract: A method of determining or predicting a value P.sub.x of a property (e.g. octane number) of a material X or a property of a product of a process from said material or yield of said process, which method comprises measuring the absorption D.sub.ix of said material at more than one wavelength in the region 600-2600 nm, comparing the said absorptions or a derivative thereof with absorptions D.sub.im or the derivatives thereof at the same wavelength for a number of standards S in a bank for which the said property or yield P is known, and choosing from the bank at least one standard S.sub.m with property P.sub.m said standard having the smallest average value of the absolute difference at each wavelength i between the absorption D.sub.i x (or derivative thereof) for the material and the absorption D.sub.i m (or derivative thereof) for the standard S.sub.m to obtain the P.sub.x, with averaging of said properties or yields P.sub.m when more than one standard S.sub.m is chosen.

Abstract: Lactobacillus johnsonii strain CNCM I-1225 adheres to Caco-2 cells and inhibits adhesion thereto by enterovirulent and enteroinvasive pathogens.

Abstract: Stomach ulcers are treated by administering orally to a human in need thereof an anti-Helicobacter pylori effective amount of a composition containing, in combination with an ingestible support, a culture of Lactobacillus johnsonii strain CNCM I-1225 or a supernatant phase isolated from a culture of Lactobacillus johnsonii strain CNCM I-1225.

Abstract: Bifidobacterium breve CNCM I-1226, Bifidobacterium infantis CNCM I-227 and Bifidobacterium longum CNCM I-1228 adhere to and competitively exclude pathogenic bacteria from Caco-2 cells. The strains may be incorporated into yogurts, acidified milks and other food compositions.

Abstract: Dental caries are prevented by contacting teeth with an edible composition containing micellar casein which has been isolated from an animal milk and which is incorporated in the composition in an amount sufficient to inhibit oral colonization by Streptococcus sobrinus.

Abstract: Kappa-caseino-glycomacropeptide (CGMP) is industrially produced from a whey product concentrated in proteins partly freed from lactose by selective precipitation of the residual whey proteins with ethanol from the supernatant collected after separation of the flocculate obtained by heat treatment in acidic medium.

Abstract: Antibacterially active compositions are prepared from a proteolytic enzymatic digestate of glycopeptides obtained from a protein isolate enriched with soya glycoprotein 7S or with bean glycoprotein II. The glycopeptide digestate is treated with endo-.beta.-N-acetylglucosaminidase H to obtain oligosaccharide compositions which then also may be treated with exo-.alpha.-mannosidase to obtain further oligosaccharide compositions.

Abstract: A valve designed for the prevention of leakage between two or more ports when the valve is in its off position and where leakage occurs at a port seal as shown and described. In this design, each port is sealed when the valve is in the off position, and an open area vented to atmosphere is provided between each of the port seals, whereby if a seal should leak, the fluid will pass to the atmosphere by way of a vent, and will not come in contact with any other sealed port in the valve. The vented chamber separates each port seal from other port seals in the valve. The vented chamber is exterior to the valve and is not a part of the inside of the valve member such as a passage therethrough.

Abstract: Adhesion of bacteria in the buccal cavity which are responsible for the formation of dental plaque and caries is inhibited by kappa-caseino-glycopeptide compounds and desialylated derivaties thereof contained in compositions having a form suitable for being empolyed for treating the bacteria in the buccal cavity.

Abstract: Kappa-caseino-glycopeptide compounds and desialylated derivatives thereof and compositions containing the same are employed for treating bacteria in the buccal cavity which are responsible for the formation of dental plaque and caries.

Abstract: Adherence of pathogenic bacteria having type I fimbriae to animal cells is inhibited by compositions having active constituents which are new glycopeptide and/or oligosaccharide compounds. The active constituent compounds are prepared enzymatically from vegetable flour which contains reserve glycoproteins rich in oligomannosides, preferably from a fraction enriched with soya glycoprotein 7S or with bean glycoprotein II, although glycopeptides from ovalbumin may be utilized for the preparation of the compounds. The compounds have a polymannosidic basic structure similar to that of epithelial cells which is recognized by various pathogenic bacteria and which results in neutralizing the bacteria so they do not adhere to the cells. Compositions including the active constituent compounds are effective for use in the prophylaxis, treatment and diagnosis of infectious diseases, especially those caused by coliform bacteria, and also for use in the disinfection of surfaces.

Abstract: An installation for manufacturing reinforced concrete elements, in particular prestressed concrete slabs or pre-slabs, by means of a bench including a manufacturing area of predetermined shape, together with a molding apparatus. Memory means (46) are provided for storing building data relating to the elements to be manufactured and concerning at least the geometry thereof, together with tracing means (48) for marking on the manufacturing area (16) the locations of at least some of the walls placed thereon and constituting portions of the molding apparatus.

Abstract: The invention concerns a hydraulic disconnector to separate an inflow circuit from outflow from an outflow circuit.Controlled by the membrane, the valve opens the drainage of chamber if the outflow circuit flows back in the direction of the arrow. The spring opens this drainage even if the membrane is punctured.
