The positive significance of consumers involving in enterprise NPD has been generally realized. But the involvement condition in each stage of the NPD and involving modes remain to be further research. This paper USES field experience and questionnaire survey to research consumers involving in Chinese SMEs NPD. Main content includes typical stages of NPD, which NPD stages consumers are involved...

We demonstrate, for the first time, to our knowledge, a diode-pumped passively mode-locked Nd:YVO4 laser, operating on the 4F(3/2)-4I(9/2) transition of the neodymium ion at 914 nm. We obtained 8.8 ps pulses at approximately 914 nm at a repetition rate of 94 MHz, and an averaged output power of 87 mW by using a semiconductor saturable absorber mirror.

A 65-year-old female developed elevated intraocular pressure (IOP) with angle closure in the right eye. The fundus examination revealed vitreo-retinal hemorrhage that had occurred after neodymium-doped yttrium aluminum garnet (Nd:YAG) laser iridotomy. The retinal hemorrhage resolved spontaneously. This is a rare complication that occurs when the IOP is lowered rapidly. Ocular decompression reti...

The paper presents electrical actuator design considerations introduced by exploiting new magnetic material characteristics. The materials considered are amorphous alloy ribbons as well as neodymium alloy permanent magnets involving very low eddy current losses. Such materials enable electric machine operation at higher frequencies compared with the standard iron laminations used in the traditi...

Room temperature random lasing action is demonstrated for the first time in a low concentrated neodymium doped vanadate crystal powder. Laser threshold and emission efficiency are comparable to the ones obtained in stoichiometric borate crystal powders. The present investigation provides a complete picture of the random lasing characteristics of Nd-doped vanadate powder both in the spectral and...

A photo-radiation method was applied to decompose oxalate precipitates so that it can be dissolved into dilute nitric acid. This work has been studied as a part of partitioning of minor actinides. Minor actinides can be recovered from high-level wastes as oxalate precipitates, but they tend to be coprecipitated together with lanthanide oxalates. This requires another partitioning step for mutua...
