An influenza vaccine adjuvanted with a sub-micron oil-in-water emulsion elicits significantly higher immune responses in human pediatric populations. Compared to an existing unadjuvanted pediatric influenza vaccine, the adjuvanted vaccines provided herein can induce in children a longer persistence of high serum antibody titers and also longer seroconversion and seroprotection. The improvement in immune responses is seen for both influenza A virus and influenza B virus strains, but it is particularly marked for influenza B virus. Moreover, while the existing vaccine provides poor immunity in children after a single dose, the adjuvanted vaccine provides high seroprotection rates against the influenza A virus H3N2 subtype even after a single dose. Furthermore, the adjuvanted vaccine offers significantly better seroprotection against mismatched strains of influenza A virus.

The invention relates to a method for producing electrochromic devices, in particular that having a large working surface area and which does not produce a volumetric shrinkage and can operate during a long maintenance of electrocoloured state of an electrochromic compound, high control voltages and polarity inversion. The inventive electrochromic device comprises at least two electrodes (1, 2), at least one of them being optically transparent. A closed sealed space is formed between said electrodes and filled with the electrochromic compound which is embodied in the form of a solid-like film. The inventive method for producing the electrochromic device consists in prefabricating an initial electrochromic compound in the form of a dispersed electrochromic system which contains at least a suspension and / or colloid. The dispersed medium of said system is embodied in the form of an electrochromic solution containing a liquid solvent, cathode and anode components, a disperse phase being embodied in the form of a finely dispersed polymer. Afterwards, the initial electrochromic compound is deaerated, thereby eliminating dissolved oxygen and air introduced by said finely dispersed polymer, and is used for filling the space between the electrodes.

An updateable system and method of recording a hologram on a media simultaneously reduces the writing time and increases persistence without sacrificing diffraction efficiency. A voltage kick-off technique controls the bias electric field applied to a photorefractive polymer media in conjunction with the application of the writing beams and dark decay. Essentially the voltage kick-off technique applies a high electric field above the optimal field while the writing beams are on and reduces the electric field when the writing beams are off during dark decay. The voltage kick-off technique produced two separate unexpected results. First, when the writing beams are turned off and the electric field is lowered the diffraction efficiency continues to increase until it reaches a maximum efficiency that is within a few percent of that achieved by writing at the optimal field until steady-state is achieved. Second, the decay time constant is much larger than expected producing a much longer persistence without sacrificing diffraction efficiency or writing time.

Disclosed is a method for grinding a spring with high quality and high efficiency, comprising the steps as follows: firstly, at least one of an upper grinding wheel (1) and a lower grinding wheel (2) is configured to comprise an inner grinding wheel (21) and an outer grinding wheel (24), wherein the inner grinding wheel (21) is fitted in the outer grinding wheel (24); the inner grinding wheel (21) or the outer grinding wheel (24) is driven by a transmission mechanism, the inner grinding wheel (21) and the outer grinding wheel (24) rotating in opposite directions; after a complete spring is fed to a space between the upper grinding wheel (1) and the lower grinding wheel (2), the complete spring is moved back and forth in the plane of the grinding wheels; and then the upper grinding wheel (1) is moved downwardly such that two end faces of the spring are ground by the grinding wheels, and when the height of the ground spring meets the requirement, the upper grinding wheel (1) is stopped moving downwardly and is returned to the original point later. Then, the ground spring movement is stopped and it is moved away from the space between the two grinding wheels, i.e., the complete spring is removed. In this way, the spring is ground in a revolving state, which can improve the yield and quality of ground springs, save energy and protect the environment, and result in a low cost of grinding, a simple structure, low cost for manufacturing parts, long persistence in precision of mechanisms, and good stability.
