Differential Sensitivity of Nitrogen-Fixing, Filamentous Cyanobacterial Species to an Organochlorine Insecticide - 6, 7, 8, 9, 10, 10- Hexachloro-1, 5, 5a, 6, 9, 9a-Hexahydro-6, 9- Methano-2, 4, 3-Benzodioxathiepine-3-Oxide
Application of pesticides in the paddy fields has deleterious effects on non-target organisms including cyanobacteria which are photosynthesizing and nitrogen fixing micro-organisms contributing significantly towards soil fertility and crop yield. Pesticide contamination in the paddy fields has manifested into a serious global environmental concern. To study the effect of one such pesticide, th...

The compound named in the title was prepared from N1,N4-diphenethylterephthalamide 1. The resulting bis terephthalamide was subjected to an intramolecular α-amidoalkylation reaction with paraformaldehyde in the presence of heterogeneous catalyst TfOH/SiO2 to obtain 1,4-phenylenebis[(6,7-dimethoxy-3,4-dihydroisoquinolin-2(1H)-yl)methanone]. The structure of the newly synthesized compound was det...

46 There is a significant body of research examining the intelligibility of sinusoidal replicas of 47 natural speech. Discussion has followed about what the sinewave speech phenomenon might 48 imply about the mechanisms underlying phonetic recognition. However, most of this work has 49 been conducted using sentence material, making it unclear what the contributions are of 50 listeners’ use of l...

The gene for the prototype acute phase reactant, Creactive protein, has been isolated from two X phage libraries containing inserted human DNA fragments using synthetic oligonucleotide probes. Nucleotide sequence analysis indicates that after coding for a signal peptide of 18 amino acids and the first two amino acids of the mature protein, there is an intron of 278 base pairs followed by the nu...
