Abstract: A process for determining S-nitrosothiols, in particular S-nitrosoglutathione, in biological fluids that is easy, selective, cheap with respect to the prior art, which requires the use of equipment commonly available in laboratories, at low cost, which can be used by not qualified operators. The process is based on the hydrolysis of S-nitrosoglutathione (GSNO) by an enzyme, in particular ?-glutamyltranspeptidase (GGT). This enzyme hydrolizes the residual ?-glutamyl of GSNO for giving glutamate (GIu) and S-nitroso-cysteinylglycine (GIyCySNO). In the presence of ions of transition metals GGT speeds up the release of NO since the intermediate that is formed, the GIyCySNO, is much more sensitive to a metal-dependent decomposition. Advantageously, the amount of nitric oxide present in the sample is measured through a reaction thereof with 4,5 diaminof luorescein (DAF-2), said reaction creating a fluorescent compound in an amount proportional to the S-nitrosothiol amount present in the sample.

Abstract: The present invention relates to a field emission apparatus and a method of driving the field emission apparatus, which has a three-pole structure of dual emitters formed on both first and second electrodes of a rear substrate in order to obviate a distinction between a gate and a cathode, thus enabling dual field emission. In such a field emission apparatus, a ground is formed between an anode and a point of the first and second electrodes of the rear substrate, and a square wave is applied thereto in order to alternately generate field emission in the first and second electrodes, thus increasing a light-emitting area and emission efficiency, decreasing a driving voltage and consumption power, saving the manufacturing cost and manufacturing time, and accomplishing a longer lifespan.

Abstract: A closure for a multiple component container includes an insert (12), a piston (20) and a cap (10). The insert (12) and the piston (20) define a reservoir and the insert (12) comprises a fixed cylindrical wall (26) and a movable wall (32) connected thereto and movable with respect thereto by the action of gas pressure within the reservoir. The movable wall (32) has a discharge aperture (36) formed therein. The cap (10) comprises a closure plate (14), integral with whose outer edge is a depending skirt (16), by means of which the cap may be secured to a container. The closure plate (14) cooperates with the piston (20) such that movement of the closure plate towards the insert (12) results in movement of the piston also in the same direction. The piston (20) forms a sliding seal with the internal surface of the fixed cylindrical wall (26). A valve member (22) is integral with, the piston (20) and is slidably received in and seals the discharge aperture (36).

The core portion of the active material is made of a spinel manganese-containing material substituted with fluorine or sulfur, having 4V-grade potential and showing low-cost and high-output characteristics, and the shell portion, which comes into contact with an electrolyte, is made of a spinel transition metal-containing material, having excellent thermal stability and cycle life characteristics and showing low reactivity with the electrolyte. Thus, the cathode active material shows significantly improved cycle life characteristics and excellent thermal stability.

Abstract: A flow measuring apparatus measures a fluid flow within a conduit including a wall. The apparatus includes a transducer arrangement including at least two transducers for alternately emitting and receiving ultrasonic radiation through the conduit wall and the flow. The apparatus also includes a signal processing arrangement for generating signals to excite the transducer arrangement and for processing received signals provided by the transducer arrangement for generating output signals from the signal processing arrangement indicative of properties of the flow. The transducer arrangement in cooperation with the conduit provides a first path for Lamb-wave ultrasonic radiation coupling directly from a first of the at least two transducers, to a second of said at least two transducers to generate a first received signal.
