Information on the binding of organic ligands to metal (hydr)oxide surfaces is useful for understanding the adsorption behaviour of natural organic matter on metal (hydr)oxide. In this study, benzoate and salicylate were employed as the model organic ligands and aluminum hydroxide as the metal hydroxide. The attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectra revealed tha...

The proposal by Hubbard et al. (1) that "Very High Alumina basalt" ("VHA basalt") may represent an important primary lunar magma type neglects consideration of certain well-characterized high-magnesium highland rocks, among them spinel troctolite from Luna 20 (2) and Apollo 16 samples (3) and dunite from Apollo 17 samples (4), and the possibility that "VHA basalt" may in fact have originated by...

Occurrence of sediments hosted smooth surfaced flat / discoid black and pink coloured bimodal carbonatite bombs, lapillus, pisolites and ashes in semi-unconsolidated conglomerate covering an area of 90 sq.km is reported from Thiruvalangadu (13 o 10’36”N-76 o 44’38”E) area situated 60 km WNW of Chennai. The carbonatite materials are uniformly composed of flow-oriented fine-grained calcites <0.02...

The incidence and severity of tachyarrhythmias, both supraventricular tachycardia and ventricular tachycardia may increase during pregnancy. Although the reasons for this observation are unclear, some explanations have been proposed: increased awareness, haemodynamic, hormonal, autonomic, and emotional changes related to pregnancy, which may include: increases in plasma catecholamine concentrat...

Congo red, which has a complex molecular structure with various diazo aromatic groups, is widely used in textile industry as an anionic dye. The purpose of this study was to investigate the degradation of Congo red in laboratory solution which had the chemical properties of the rinse waters of textile manufacturing dye-houses and the samples with Congo red alone wastewater by ozonation and to o...
