The present invention relates to the field of the detection, analysis and/or determination of matter or particles suspended in fluid. In one particular form, the present invention relates to smoke detectors, which detect unwanted pyrolysis or combustion of material. In another form, the present invention relates to smoke detectors of the early detection type, and which may be applied to ventilation, air-conditioning or duct monitoring of a particular area. In yet another form, the present invent...

The present invention relates to an isolated nucleic acid molecule comprising a sequence of nucleotides encoding a .beta.-ketoacyl ACP synthase II from a plant, or a variant, derivative, homolog or analog of said .beta.-ketoacyl ACP synthase II. The invention also relates to an isolated .beta.-ketoacyl ACP synthase II enzyme from a plant. The polynucleotide sequences of the present invention may be used inter alia for the generation of cells or plants comprising such cells which have a modified ...

Sulphur-containing olefinic feedstocks are oligomerized over zeolite catalysts.

A gas injector that is coupled to the pump strainer basket housing drain port of a pump-circulated system is disclosed. The gas injector that may be installed in a way that is less invasive than currently used gas injection systems to pre-existing plumbing of a pump system and that allows for more efficient gas absorption in water than currently used gas injection systems. The gas injector may be used with all currently existing pump systems.

In a communication terminal where a running application is not managed by an OS (operating system), a message is received without a communication connection being established, and if the message is destined for a running application, receipt of the message is notified to the running application. In mobile device MS, CPU 6 writes in key information area 73 of RAM 7 key information for identifying a Java application which is being run using KVM program 84, using OS software 82 and JAM program 86 s...

In a circumstance in which light is emitted from many electronic flashes, e.g., a press conference hall or a wedding hall, light emission from other electronic flashes overlaps preliminary light emission performed before main light emission. This decreases the photometry accuracy with respect to preliminary light emission and makes it difficult to perform proper flash exposure. In a camera system designed to perform preliminary light emission before main light emission, photometry is performed a...

In one embodiment, a linear regulator is formed with a variable miller compensation circuit that varies a zero of the linear regulator proportionally to a load current supplied by the regulator.

Storage circuits (180-183 and 280-281) may be used for low power operation while allowing fast read access. In one embodiment (e.g. circuit 100), shared complementary write bit lines (101, 102), separate read bit lines (103-106), a shared read word line (107), and separate write word lines (108-111) are used. In an alternate embodiment (e.g. circuit 200), shared complementary write bit lines (201, 202), a shared read bit line (203), separate read word lines (206-207), and separate write word lin...

A solid, homogeneous and essentially random copolymer of styrene and isobutylene having a number average molecular weight of from about 1000 to about 4000, a heterogeneity index of from about 1.50 to about 2.25 and a styrene content of from about 40 to about 90 weight percent with its higher molecular weight fractions having a higher styrene content than the average styrene content of the copolymer.

There is provided a rapid and less costly radioisotopic assay for measuring the concentration of folate in blood serum. This procedure utilizes .sup.3 H-pteroylmonoglutamate, unlabeled 5-methyl-tetrahydrofolic acid, and a partially purified folate binder, such as for example a folate binder extracted from hog kidney. The procedure involves radioisotopically relating the bound amounts of a labeled folate and a known folate at various concentrations of the known folate in a system containing a pre...
