The superposed lines of 611.6178 nm and 611.6179 nm from highly-excited states f2D2 and f1D2 of nickel atoms have been resolved indirectty by means of laser-excited fluorescence spectrometry using a hollow cathode lamp. The linewidths were measured to be 2.1 GHz and 2.6GHz respectively.
By the design instance of concrete shielding-slope brick with hollow core, the design method and key points of insert mold are discussed, the key parts namely mold cavity material selection and heat treatment of insert mold are introduced in detail, so as to improve the long-term stability of die quality, it provides important experience to insert mold design.
The abnormal hollow core and thick peel are often found in no seed watermelon production because of lower germinating and survival rate, slow growth of young seedlings caused by the imfavourable condition of low temperature, rainy climate and scant sunshine in spring, Guizhou.
The results showed that the diurnal course of net photosynthetic rate displayed a two-peak pattern, that of stomatal conductance displayed a hollow pattern, and that of transpiration rate displayed a signal-peak pattern.
For the sake of contrast, cells were also expanded in a T-flask using a hollow-fiber membrane as carrier and in a rotating wall vessel bioreactor (RWVB) using a microcarrier.
Under the low back-pressure ambient conditions, the spray behavior exhibited a hollow cone with wide spray angle and initial spray slug at the tip, while the spray presented a solid cone in the case of high back-pressure.

The quantum confinement in CuCl nanocrystals is theoretically calculated under the assumption that nanocrystals have a hollow core.
The effect of cladding aperiodicity on the properties of modes guided in the hollow core of a microstructure fiber is examined.
Waveguide modes of microstructure fibers with a hollow core and a two-dimensionally periodic cladding are studied experimentally and theoretically.
The spectrum of modes guided in the hollow core of these fibers displays isolated maxima, indicating that waveguiding is supported due to the high reflectivity of the fiber cladding within photonic band gaps.
The main properties of the spectrum of modes guided in a hollow core of a photonic-crystal fiber and radiation intensity distribution in these modes are qualitatively explained in terms of the model of a periodic coaxial waveguide.
The lowest amount of food ingested and voided feces, the lowest nutritional index, slowest development, lightest pupae and most mortality were found in those pine caterpillar larvae fed with pine needles which were 50% damaged.
Furthermore, sediment-voided convection caused by the settling lutocline generates significant turbulent kinetic energy dissipation and reduces floe size at the depth where the convective mixing happens.
Thus, 45 % of the patients with abnormal voided urine samples did not need antimicrobials.
Measurements were made of voiding time, time for 50% emptying, average flow rate, ejection fraction, post-void residual urine volume, voided volume, and total bladder volume.
Diagnosis of UTI is usually based on quantitation of uropathogens in voided urine.
