Effects of organic-waste compost addition on sesame growth, yield and chemical composition

The agronomic aspects of some organic waste compost applications to sesame plants grown on sandy soil were investigated. Different rates and combinations from biosolids (BS), municipal solid waste (MSW) and water hyacinth (W) compost, incorporated with or without shale deposits (tafla) at 8%, were used to treat the sandy soil. Dry matter accumulation was used as an indicator of the effectiveness of such treatments on plant growth. In addition, the contents of nitrogen-phosphorus-potassium, chlorophyll, total protein, oil and carbohydrates were determined in plant tissue as physiological parameters. Heavy metal contents (Fe, Mn, Zn, Cu, Co, Ni, Cd, Pb) in seeds samples were determined. Results indicated that all compost treatments stimulated sesame growth and enhanced its pigment, carbohydrate and mineral contents. While the chemical constituents of sesame seeds (oil, carbohydrate and total protein) showed no variation when expressed as relative data (%), the absolute results expressed as gram per plant exhibited significant increases. The maximum levels (μg g⁻¹) of tested metals in seeds did not exceed 226 Fe, 12.5 Mn, 81. 7 Zn, 23.7 Cu, 3.8 Co, 24.6 Ni, 5.4 Pb and 1.72 Cd, which are below the reported concentrations at which phytotoxicity could occur.

A theoretical study of hydrogen-bonded molecular clusters of sulfuric acid and organic acids with amides

Amides, a series of significant atmospheric nitrogen-containing volatile organic compounds (VOCs), can participate in new particle formation (NPF) throught interacting with sulfuric acid (SA) and organic acids. In this study, we investigated the molecular interactions of formamide (FA), acetamide (AA), N-methylformamide (MF), propanamide (PA), N-methylacetamide (MA), and N,N-dimethylformamide (DMF) with SA, acetic acid (HAC), propanoic acid (PAC), oxalic acid (OA), and malonic acid (MOA). Global minimum of clusters were obtained through the association of the artificial bee colony (ABC) algorithm and density functional theory (DFT) calculations. The conformational analysis, thermochemical analysis, frequency analysis, and topological analysis were conducted to determine the interactions of hydrogen-bonded molecular clusters. The heterodimers formed a hepta or octa membered ring through four different types of hydrogen bonds, and the strength of the bonds are ranked in the following order: SOH???O > COH???O > NH???O > CH???O. We also evaluated the stability of the clusters and found that the stabilization effect of amides with SA is weaker than that of amines with SA but stronger than that of ammonia (NH₃) with SA in the dimer formation of nucleation process. Additionally, the nucleation capacity of SA with amides is greater than that of organic acids with amides.
