The north Indian states of Haryana and Punjab are believed to be the key sources air pollution in National Capital Region due massive agricultural waste burning crop harvesting seasons. However, with pandemic COVID-19 hitting country, usual practices were disrupted. preventive lockdown led restricted vehicular industrial emissions caused labours leave business Punjab. With changed scenario 2020...
The principle results and conclusions of research into slush drag, wheel spray and aquaplaning, using a moving runway and water layer model test facility, are described. The method has proved a valuable compliment to full scale research into these problems. Suggestions for future research are made.
Remote sensing is often used to assess rangeland condition and biophysical parameters across large areas. In particular, the relationship between the Normalized Difference Vegetation Index (NDVI) and above-ground biomass can be used to assess rangeland primary productivity (seasonal carbon gain or above-ground biomass “yield”). We evaluated the NDVI–yield relationship for a southern Alberta pra...
In the title compound, {[Co(C(10)H(8)N(2))(H(2)O)(4)](ClO(4))(2)·2C(10)H(8)N(2)·2H(2)O}(n), slightly distorted octa-hedrally coordinated Co(II) ions situated on inversion centers are linked into polycationic chains through 4,4'-bipyridine tethering ligands. These are connected into supra-molecular layers by hydrogen bonding involving aqua ligands, perchlorate anions and uncoordinated water mol-...
The title compound catena-poly[aqua-sodium-μ(2)-aqua-μ(3)-2-nitro-cinnamato], [Na(C(9)H(6)NO(4))(H(2)O)(2)](n), the sodium salt of trans-2-nitro-cinnamic acid, is a one-dimensional coordination polymer based on six-coordinate octa-hedral NaO(6) centres, comprising three facially related monodentate carboxyl-ate O-atom donors from separate ligands (all bridging) [Na-O = 2.4370 (13)-2.5046 (13) Å...
In the title compound, [Cu(2)(C(8)H(4)BrO(4))(4)(C(16)H(20)N(4))(H(2)O)(2)], slightly distorted square-planar-coordinated Cu(II) ions are bound by one aqua ligand and two monodentate 3-bromo-5-carb-oxy-benzoate anions, and linked into a centrosymmetric dinuclear mol-ecule by a bridging 1,4-bis-(pyridin-4-ylmeth-yl)piperazine (4-bpmp) ligand. In the crystal, mol-ecules are connected into a supra...
