  • Biodiesel production from crude Jatropha

    15-11-2014· Calcium-based, CaO–NiO (calcium nickel) and CaO–Nd 2 O 3 (calcium neodymium) mixed oxides, were synthesized via co-precipitation process. Non-edible crude Jatropha curcus oil (JCO) was used as feedstocks for fatty acid methyl esters (FAME) synthesis in the presence of CaO–NiO and CaO–Nd 2 O 3 mixed oxides.

  • Selective inhibition of constitutive nitric oxide

    Abstract. L-NG-Nitroarginine (NA) inhibited both the L-arginine oxidation and the L-arginine-independent NADPH oxidation reactions catalyzed by the calcium/calmodulin-dependent constitutive nitric oxide synthase (cNOS) from bovine brain. NA binding did not require calmodulin, calcium, or NADPH. The onset of inhibition was slow with a second-order

  • A calcium-induced calcium influx factor, nitric

    Because nitric oxide synthases are present in astrocytes, we imaged the formation of nitric oxide in cultured murine cortical astrocytes using DAF-FM (4-amino-5-methylamino-2',7'-difluorofluorescein diacetate). We demonstrated that physiological concentrations of ATP induced a Ca2+-dependent production of nitric oxide.

    Stomatal closure in response to the hormone abscisic acid (ABA) is mediated by a complex signaling network involving both calcium-dependent and calcium-independent pathways (Assmann and Shimazaki, 1999; Webb et al., 2001), activated by several signaling intermediates (Schroeder et al., 2001) that include hydrogen peroxide (Miao et al., 2000; Pei et al., 2000;Zhang et al., 2001) and lipids such as sphingosine-1-phosphate (Ng

  • A Simplified Guide to the Relationship Between

    When calcium carbonate precipitates, it uses up a fixed ratio of calcium and carbonate (1:1, or about 20 ppm of calcium for each 1 meq/L (2.8 dKH) of alkalinity). This ratio is the same as corals use to deposit their calcium carbonate skeletons. Abiotic precipitation of calcium carbonate, like coral skeletal
