The crystal structure of the title compound (26DMPCA), C(10)H(12)ClNO, is closely related to those of side-chain-unsubstituted N-(2,6-dimethyl-phen-yl)acetamide and side-chain-substituted 2,2,2-trichloro-N-(2,6-dimethyl-phen-yl)-acet-amide and N-(2,6-dimethyl-phen-yl)-2,2,2-trimethylacet-amide, with slightly different bond parameters. The mol-ecules in 26DMPCA are linked into chains through N-H...

Rhodospirillum rubrum and Rhodopseudomonas capsulata were able to grow anaerobically in the dark either by a strict mixed-acid fermentation of sugars or, in the presence of an appropriate electron acceptor, by an energy-linked anaerobic respiration. Both species fermented fructose without the addition of accessory oxidants, but required the initial presence of bicarbonate before fermentative gr...

In a previous genomic analysis, using somatic methyltransferase (DNMT) knockout cells, we showed that hypomethylation decreased the expression of as many genes as were observed to increase, suggesting a previously unknown mechanism for epigenetic regulation. To address this idea, the expression of the BAG family genes was used as a model. These genes were used because their expression was decre...

Reactions of 5-hydrazino-1,3-dimethyl-4-nitro-1H-pyrazole (1) with substituted benzaldehydes (2-5) in methanol gave the new substituted benzaldehyde (1,3-dimethyl-4-nitro-1H-pyrazol-5-yl)hydrazone Schiff base ligands (6-9) benzaldehyde (1,3-dimethyl-4-nitro-1H-pyrazol-5-yl)hydrazone (H-BDH, 6), 2,3-dimethoxybenzaldehyde (1,3-dimethyl-4-nitro-1H-pyrazol-5-yl)hydrazone (MeO-BDH, 7), 4-chlorobenza...

• The salts with protonated bipyridines and [W(CN) 6 (bpy)] 2- were synthesized. layered structure of compared to their analogues alkali metal cations. dimethyl substituted bipyridine as a cation shows 3D dimensionality. cation-anion distance was discussed in relation position the UV-Vis bands. ion-pair-charge-transfer transitions these found 8 ] 4− analogues. series 2− 2,2′-bpy (1), 4,4′-bpy (...

This article examined the biological removal of high concentrated sulfamethazine (SMZ) antibiotics by the acclimatized activated sludge in lab-scale SBRs system. The removal of SMZ was characterized by a quick adsorption and a slow process of biodegradation. The adsorption capacity of activated sludge for SMZ was 44 and 47 µg SMZ/g SS, respectively, with the initial SMZ concentrations of 1 and ...
