[1] High-resolution images from Chandrayaan-1 Terrain Mapping Camera and Lunar Reconnaissance Orbiter Camera reveal landslides and gully formation on the interior wall of a 7 km-diameter simple crater emplaced in Schrödinger basin on the farside of the Moon. These features occur on the steep upper crater wall, where the slope is ~35 . The gullies show a typical alcove-channel-fan morphology. So...

The title compound, C(14)H(17)N(5)O, a 1,2,3-triazole derivative of benzoxadiazole (C(14)H(17)N(5)O), was synthesized via Cu-catal-ysed azide-alkyne cyclo-addition (CuAAC) from the corres-ponding n-octyne and 4-azido-benzoxadiazole. The benz-oxa-diazole and triazole rings show a roughly planar orientation [dihedral angle between the ring planes = 12.18 (5)°]. The alkane chain adopts a zigzag co...

The title compound, C26H22N4O5 (systematic name: methyl 2-eth-oxy-1-{4-[2-(5-oxo-4,5-di-hydro-1,2,4-oxa-diazol-3-yl)phenyl]benz-yl}-1H-1,3-benzo-diazole-7-carboxyl-ate ethyl acetate hemisolvate), was obtained via cyclization of methyl (Z)-2-eth-oxy-1-{(2'-(N'-hy-droxy-carbamimido-yl)-[1,1'-biphen-yl]-4-yl)meth-yl}-1H-benzo[d]imidazole-7-carboxyl-ate with diphen-yl carbonate. There are two indep...

This paper presents results from an extensive experimental study on hydraulic performance of new rectangular bridge deck drains developed by the Texas Department of Transportation (TxDOT) Bridge Division. It fits between the deck reinforcement with the top of the drain flush with the bridge surface and does not interfere with the structural connection of the bridge rail to the deck. Experiments...

Soil infiltration processes manage runoff generation, which in turn affects soil erosion. There is limited information on infiltration rates. In this study, the impact of vine age on soil bulk density (BD) and hydraulic conductivity (Ks) was assessed on a loam soil tilled by chisel plough. Soil sampling was conducted in the inter row area of six vineyards, which differed by the age from plantin...

This research investigation was aimed at demonstrating the technical and economic feasibility of waste stabilization ponds (WSP) under the climatic conditions of a subtropical region. A pilot plant was designed and constructed at the Karachi University Campus (KUC) for the treatment of domestic wastewater. An intensive analytical programme was followed for 24 months to evaluate the performance ...

There are two mol-ecules in the asymmetric unit of the title compound, C(23)H(21)BrN(2)O(4), which differ in the conformation of their ethoxy residues, i.e. almost co-planar with the pyridine ring in one mol-ecule [C-O-C-C = -174.0 (2)°] but almost perpendicular in the other [C-O-C-C = 92.8 (3)°]. The dihedral angles between the central pyridine ring and the 4-bromo-phenyl and 2,4,5-trimethoxy-...

This paper presents the laboratory test results of vertical infiltration on two soil columns of finer over coarser soils subject to simulated rainfalls under conditions of no-ponding at the surface and constant head at the bottom. The main objectives were to evaluate the effect of rainfall intensity and duration; and to provide experimental evidence for soil water redistribution and hysteresis....

DEM-based topographic characterization and quantification of surface depression storage are critical to hydrologic and environmental modeling. Mixed conclusions have been obtained from previous studies on the relationship between maximum depression storage (MDS) and DEM grid spacing, which is affected by different factors, such as topographic characteristics, surface delineation methods and DEM...
