Humic acid in the form of sodium humate and fulvic acid markedly increased the growth and efficiency of nitrogen fixation
ofAzotobacter chroococcum. Fulvic acid proved more effective than the sodium humate. The effectiveness of these substances was more pronounced in increasing
the number of cells than affecting the nitrogen fixation. The increases in growth and nitrogen fixation were in direct proportion
to the quantities of sodium humate and fulvic acid applied up to 500 and 700 ppm respectively. Thereafter the growth was restricted,
although it was not inhibited even at 1,400 ppm. 相似文献

Although zinc in traces is essential for the growth and well being of the animal, however a long-term treatment has been found equally toxic to the liver and kidney. Present report describes its effects on few key enzymes viz. alkaline phosphatase, acid phosphatase, 5-nucleotidase, lipase, glucose-6-phosphatase, and cholinesterase in the liver of rat, Rattus rattus albino. Histochemical observations have provided visual evidences on Zn-induced dysenzymia. The results have further been interpreted in terms of its effects on cellular organelle, levels of enzyme protein and microenvironment of the hepatic parenchyma. 相似文献

The CaAlBO4:RE (RE = Dy3+, Eu3+, Sm3+) phosphor were prepared via combustion synthesis and studied by X-ray diffraction (XRD), Fourier-transform infrared (FTIR) analysis, scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), photoluminescence (PL) spectra and CIE coordinates. The phase formation of the obtained phosphor was analyzed by XRD and the result was confirmed by standard PDF Card No. 1539083. XRD data successfully indicated pure phase of CaAlBO4 phosphor. The crystal structure of CaAlBO4 phosphor is orthorhombic with space group Ccc2 (37). The SEM image of CaAlBO4 phosphor reveals an agglomerated morphology and non-uniform particle size. The EDS image provides evidence of the elements present and the chemical makeup of the materials. Under the 350 nm excitation, the emission spectrum of Dy3+ activated CaAlBO4 phosphor consists of two main groups of characteristic peaks located at 484 and 577 nm which are ascribed to 4F9/2 → 6H15/2 and 4F9/2 → 6H13/2 transition of Dy3+ respectively. The PL emission spectra of CaAlBO4:Eu3+ phosphor shows characteristics bands observed around 591 and 613 nm, which corresponds to 5D0 → 7F1 and 5D0 → 7F2 transition of Eu3+ respectively, upon 395 nm excitation wavelength. The emission spectra of Sm3+ activated CaAlBO4 phosphor shows three characteristic bands observed at 565, 601 and 648 nm which emits yellow, orange and red color. The prominent emission peak at the wavelength 601 nm, which is attributed to 4G5/2 → 6H7/2 transition, displays an orange emission. The CIE color coordinates of CaAlBO4:RE (RE = Dy3+, Eu3+, Sm3+) phosphor are calculated to be (0.631, 0.368), (0.674, 0.325) and (0.073, 0.185). As per the obtained results, CaAlBO4:RE (RE = Dy3+, Eu3+, Sm3+) phosphor may be applicable in eco-friendly lightning technology. 相似文献

Genetic markers and malaria. Observations in Gujarat, India 总被引:2,自引:0,他引:2
189 healthy controls and 175 patients suffering from malaria vivax have been investigated with regard to associations between this disease and 22 genetic polymorphisms of the blood (ABO, MN, Ss, Rh, Kell, P, Lutheran, Kidd, Duffy, Diego, Xg; ABH-Secretor; Hp, Gc, Gm, Km; aP, AK, PGM1, 6-PGD, EsD; Hb variants) Significant associations could be demonstrated only for P and Hp systems, though in accordance with other investigations it cannot be excluded that the ABO system plays also a role in this connection. 相似文献
