An improved multi-shear algorithm is proposed to reconstruct a two-dimensional wavefront from multiple phase differences measured by lateral shearing interferograms with different tilts. The effects of the tilt errors in the wavefront are analyzed and a compensation method is developed. Unbiased estimators are added to Fourier coefficients of the phase differences to eliminate the tilt errors adaptively. The algorithm is immune to the tilt errors and the wavefront under test can be recovered exactly. Computer simulation and optical test demonstrated that the proposed algorithm has higher recovery accuracy than the existing multishear algorithms. © 2014 Optical Society of America. Source

The paper established a new resonance light scattering method for determining quercetin content in water solution. It was found that in hexamine buffer solution (pH7.50), sodium-dodecylbenzene- sulfonate-hexadecyl-trimethyl- ammonium-bromide system can enhance the resonance light scattering intensity of quercetin which is in proportion to the content of quercetin in the range of 2.0×10 -9 to 5.0×10 -5mol/L. The detection limit is 5.0×10 -10mol/L. Source

Salt-sensitive wheat cultivar 'Lumai No. 15' (Lu 15) and salt-tolerant wheat cultivar 'Dekang 961' (Dk 961) were used as experimental materials. With the increase in concentration of NaCl and iso-osmotic PEG, MDA content and respiration rate of Lu 15 obviously increased and the increase of which under NaCl stress was more than that under iso-osmotic stress; however, MDA content and respiration rate of Dk 961 increased relatively less under the same stress intension. Salt stress of low concentration obviously promoted SOD activity and photosynthetic rate of leaves of Dk 961. Under salt stress of high concentration, SOD activity and photosynthetic rate of Lu 15 was obviously restricted more than that of Dk 961, and the decrease of SOD activity and photosynthetic rate of Lu 15 was more than that under iso-osmotic stress. Salt-tolerance of wheat cultivars showed negative correlation with MDA content and respiration rate, while positive correlation with SOD activity and photosynthetic rate. The significant increase in MDA content and respiration rate of salt-sensitive cultivar very likely resulted by toxic effects of Na+ under high salinity stress. Source

Reaction of molybdenyl(IV) oxide bis(2,4-pentanedionate) with N'-(3-ethoxy-2-hydroxybenzylidene)-2-methoxybenzohydrazide in methanol affords a mononuclear dioxomolybdenum(VI) complex containing MoO5N basic core. The complex has been characterized by various physicochemical techniques (IR and elemental analysis), and single crystal X-ray diffraction. X-ray crystal structure determination reveals that the complex crystallizes as monoclinic space group P21/c, with unit cell dimensions a = 9.251(1), b = 11.910(2), c = 17.636(3) Å, β = 103.220(2)°, V = 1891.7(5) Å3, Z = 4, R 1 = 0.0693, wR 2 = 0.1691. The Mo atom in the complex is octahedrally coordinated, with the tridentate ONO ligand occupying the meridional sites. Thermal stability analysis was performed. The complex shows high catalytic property for the oxidation of various olefins. © 2014 Pleiades Publishing, Ltd. Source

The effect of lime mud from paper-making process (LMP) addition on the H2 fermentation of food waste (FW) was investigated. It was found that a slight addition of LMP (1.0-4.0 g in 200 g FW) significantly enhanced the H2 fermentation performance, not only increasing the total amount of H2 produced but also accelerating the whole reaction, shortening the lag period, and increasing the H2 production rate. Fermentation stability and microbial germination were also facilitated by LMP addition. This was attributed to the existence of Ca, Fe, Mn and alkaline substances such as CaCO3 and NaOH. The batch process treating a mixture of FW and LMP was showed that the highest hydrogen production of 137.6 mL H2/g VS was achieved at final pH 5.0, adding 3 g LMP (in 200 g FW) to the fermentation process, which lag-phase time was about 2.5 h.
