Non-point source (NPS) pollution originating from agricultural development is the root cause of environmental pollution. Herein, we explore the integration of a NPS pollution model with novel spatial information technology to further understand the effects of enhanced crop development on local water resources. This study was based on land use, soil and precipitation data from studies conducted ...

2,5-Bis(pyridin-2-yl)-1,3,4-thia-diazole (denoted L) has been found to act as a bidentate ligand in the monomeric title complex, [Cu(CF(3)O(3)S)(C(12)H(8)N(4)S)(2)(H(2)O)](CF(3)O(3)S). The complex shows a distorted octahedrally coordinated copper(II) cation which is linked to two thia-diazole ligands, one water mol-ecule and one trifluoro-methane-sulfonate anion. The second trifluoro-methane-su...

Many hydrologic and water quality computer models have been developed and applied to assess hydrologic and water quality impacts of land use changes. These models are typically calibrated and validated prior to their application. The Long-Term Hydrologic Impact Assessment (L-THIA) model was applied to the Little Eagle Creek (LEC) watershed and compared with the filtered direct runoff using BFLO...

A conformational analysis of nine macrocyclic thioether musks has been carried out using molecular mechanics (MMFF), density functional theory (DFT) using both B3LYP and M06 functionals, as well as Hartree-Fock and post-Hartree-Fock (MP2) ab initio methods. 6-Thia-, 10-thia- and 4-methyl-5-thia-14-tetradecananolide, 4-thia-, 7-thia-, 11-thia- and 12-thia-15-pentadecanolide and 6-thia- and 12-th...

The bidentate 1,3,4-thia-diazole ligand, namely, 2,5-bis-(2-pyrid-yl)-1,3,4-thia-diazole (denoted L), untested as a polydentate ligand, has been found to form the monomeric title complex, [Ni(C(12)H(8)N(4)S)(2)(H(2)O)(2)](BF(4))(2). The complex shows an octa-hedral environment of the nickel cation in which the Ni(2+) ion is located on a center of symmetry, linked to two ligands and two water mo...

In the title compound, C(11)H(7)F(3)N(2)O(4)S(2), the 1,3-thia-zol-2-amine residue is almost perpendicular to the central benzene ring [dihedral angle = 84.3 (2)°]. There is a small twist between the benzene ring and the ester group [C-O-C-C torsion angle = 9.8 (6)°]. Thus, the mol-ecule has an L-shape. Inversion-related dimers are connected in the crystal packing by pairs of N-H⋯N hydrogen bon...

The house fly, Musca domestica L., is an important ectoparasite with the ability to develop resistance to insecticides used for their control. Thiamethoxam, a neonicotinoid, is a relatively new insecticide and effectively used against house flies with a few reports of resistance around the globe. To understand the status of resistance to thiamethoxam, eight adult house fly strains were evaluate...
