    Opis:
    Three Schiff bases derived from thiosemicarbazide and ketones (Vanillin, Benzophenone and Acetophenone) were used to study their antibacterial activities against some pathogenic bacteria by disc diffusion method. Of these, benzophenone thiosemicarbazone showed significant antibacterial activity as compared with that of Kanamycin. All these three compounds were found to possess cytotoxic effect. Minimum inhibitory concentration of these compounds was also determined.

    Opis:
    A new series of four transition metal complexes of a Schiff base derived from salicylaldehyde and glycine, viz. [N-salicylidene glycinato diaqua cobalt (II) dimer] (SGCo)2, [N- salicylideneglycinato-di-aqua-nickel(ll)dimer] (SGN)2, [N-salicylideneglycinato-aqua-copper(II)] (SGC) and [N-salicylidene glycinato diaqua zinc(II) dimer] (SGZ)2 have been synthesized and characterized through a rapid, simple, and efficient methodology in excellent yield. These compounds were screened for in vitro antibacterial activities against six pathogenic bacteria, such as Shigella sonnei, Escherichia coli, Bacilus subtilis, Sarcina lutea, Staphylococcus aureus and Pseudomonas arioginosa. The antibacterial activity was determined by the disc diffusion method using DMSO as solvent. The results indicate that (SGC) compound exhibit a significant antibacterial activity, depending on the bacterial strain and (SGCo)2, (SGN)2 and (SGZ)2 compounds show a moderate sensitivity even with higher doses. All these compounds were found to possess cytotoxic effect.

    Opis:
    Analgesic and anti-inflammatory activities of four transition metal complexes of a Schiff base derived from salicylaldehyde and glycine, viz. [N-salicylideneglycinato diaqua cobalt(II) dimer] (SGCo)2, [N-salicylideneglycinato-di-aqua-nickel(ll)dimer] (SGN)2, [N-salicylideneglycinato-aqua-copper(II)] (SGC) and [N-salicylideneglycinato diaqua zinc(II) dimer] (SGZ)2 were studied in swiss albino mice. 10 mg/kg (p.o) dose for each compound were selected throughout the research work. The analgesic activity was determined by acetic acid induced writhing and tail immersion methods. All such data were compared with standard drugs at the dose of 10 mg/kg (p.o. The anti-inflammatory activity of the test compounds was determined by the carragenan induced mice paw edema inhibition method.). Analgesic and anti-inflammatory activities of the test compounds at 10 mg/kg (p.o.) were quite comparable to those of standard drugs at 10 mg/kg (p.o.). All these compounds can be considered as potent analgesic and anti-inflammatory agents.

    Opis:
    In the present study, laser-induced breakdown spectroscopy (LIBS) has been applied for the determination of chromium and cadmium contents in wastewater of different canneries surrounding by leather factories. The plasma was generated with a Q-switched Nd:YAG laser having a fundamental wavelength of 1064 nm and delivers maximum pulse energy of 180 mJ. Experimental conditions were optimized to improve the sensitivity and to get a reasonable signal from the generated plasma. The results show that the concentration of chromium and cadmium are varying in different samples depending on the incoming flow of the wastewater from factories. The results from LIBS and standard analytical technique called flame atomic absorption spectroscopy (FAAS) were compared and found in good agreement within the experimental uncertainties.

    Opis:
    The chemical constituents and insecticidal activity of the pods of Senna italica (Caesalpiniaceae, Fabaceae) were investigated. From the chloroform extract of pods, physcion, chrysophanol, chrysophanol-10,10′-bianthrone, chrysophanol-physcion bianthrone and chrysophanol-isophyscion bianthrone, were isolated and characterized using different spectral methods. The GC-MS of the n-hexane extract revealed that the major chemical constituents of the oil were 2,6,-di-sec-butylphenol (36.69 %), di-n-octylphthalate (12.06 %), eicosane (5.46 %), tetratriacontane (4.87 %) and 2,2'-methylenebis[6-(1,1-dimethyl)-4-methylphenol (4.18 %). The n-hexane extract showed potent insecticidal activity (100 %) against Callosbruchus analis F. This study suggests that S. italica pods cannot be a source of sennosides but for other bioactive compounds.

    Opis:
    A short term variation of solar flare in nine months (January 2010 to September 2010) is presented. This paper review and analyze the correlation between radio flux strength measurement and solar flare in the X-ray region. The radio flux measurement data were taken from the National Research Council; Ottawa while hard X-ray emission observed by Royal Observatory of Belgium. The overall range of solar radio flux recorded in this study ranging from 68 x 10-22 Wm-2Hz-1 to 96 x 10-22 Wm-2Hz-1. As there was no class of an X of solar flare reported at all in this study, we can confirm that there are no major effects that happened on Earth and outer space such as Coronal Mass Ejections (CMEs) and solar storms. We concluded that the Sun shows a very minimum activity towards 24th solar cycle.
