Groundwater arsenic contamination has exponentially endangered the human life and complicated the efforts for obtaining and maintaining drinking water quality standards in Pakistan, particularly in the central and southern parts of the country. In the province of Sindh, groundwater arsenic concentration has reached up to 1100 μg/L against WHO limits of 10(More)
The two phenyl rings of the biphenyl unit of the title compound, C(18)H(13)NO(3), are almost coplanar [dihedral angle 6.70 (9)°]. The nitro-phenyl ring, on the other hand, is significantly twisted out of the plane of the these two rings, making dihedral angles of 68.83 (4)° with the middle ring and 62.86 (4)° with the end ring. The nitro group is twisted by(More)
We propose in this paper a three-dimensional finite element based heat transfer model for a Gallium Nitride-based Heterostructure Field-Effect Transistor (henceforth referred to as GaN HFET). Analyses were carried out to study the distribution of temperature in the HFET under steady state conditions for two different steady-current inputs. Two different(More)
With realization of changing perspective of education from a one distinctive field to support function for all fields, the present study examines the nature, strength, predictive value and significance of the unique associations of Organizational Commitment (OC) with Procedural Justice (PJ), Participation in Decision Making (PDM) and Organizational(More)
We have investigated laser induced breakdown in Ar O2 and Ne O2 gas mixtures with different O2 compositions to study possible energy transfer between excited atomic and ionic species (Ne, O, Ar, Ne, Ar, O) in these gas mixtures. Laser pulses of 5 ns duration with a repetition rate of 10 Hz from a frequency doubled Nd: YAG (λ = 532nm) delivering up to 75 mJ(More)
