Gangopadhyay, Subhashis (Elsevier, 200-09)

We have carried out a combined X-ray photoelectron spectroscopy (XPS), ultraviolet photoelectron spectroscopy(UPS), and scanning tunnelling microscopy (STM) study of the C60-Si(1 1 1) interaction where the XPS/UPS spectrometer ...

Performance of Farmer Producer Organisations in Rajasthan: An Empirical Assessment

Pandey, Ranjan; Sharma, Satyendra Kumar; Routroy, Srikanta (Routledge, 202)

India is predominantly an agrarian economy. According to the recent Economic Survey (2021–22), agriculture and allied sectors continue to be the mainstay of the Indian economy as it is the largest employer of the working ...

Performance of Hybrid THz and Multiantenna RF System With Diversity Combining

Zafaruddin, S.M. (IEEE, 202-11)

Recent studies investigate single-antenna radio frequency (RF) systems mixed with terahertz (THz) wireless communications. This article considers a two-tier system of THz for backhaul and multiple-antenna-assisted RF for ...

Information arrivals, stock price variability and market efficiency in Indian stock market

Giri, Arun Kumar (ISAE, 1984)

NB-Figures in brackets indicate percentages across the categories. cultivators owning land within the deep tubewell command area belonged only to the marginal and small size-group of farmers. The presence of the medium and ...

Magnetic resonance lineshapes in powdered and amorphous systems

Sivasubramanian, S.C. (IAS, 1986-04)

A survey is made of the theory and applications ofEPR andNMR absorption lineshapes observed in powdered and amorphous materials. The ‘spin Hamiltonian’ and ‘resonance condition’ formalisms are reviewed, andepr andnmr ...

Transformation from metallic electron charge density to electron momentum

Mishra, Rashmi Ranjan (Elsevier, 1986-12)

Electron momentum densities (EMD) in Al, V, Cr and Cu metals have been estimated from the metallic electron charge densities by applying the procedure of Burkhardt, Konya and Coulson and March. The procedure has provided ...

Impact of heavy metals on glutamine synthetase and nitrogenase activity in Nostoc calcicola.

Verma, Sanjay Kumar (J-Stage, 1987)

Density functional calculation of Compton profiles of metals using phase-space approach

Mishra, Rashmi Ranjan (Elsevier, 1987-12)

Spherically averaged electron momentum densities (EMD) in Al, V and Cu metals have been calculated by using density functional theory in the phase-space approach. Compton profiles, J(q) and expectation values 〈pn〉 have ...

Heavy metal Uptake in the Cynobacterium Nostoc calcicola.

Verma, Sanjay Kumar (IBS, 1988)

The literature on the inhibitory effect of copper on growth (Les &Walker, 1984), photosynthesis (Shiol et al, 1978) and nitrogen fixation (Rai & Raizada, 1985) in algae and higher plants is impressive. Heavy metals inhibit ...

Modal Characteristics of a doubly clad step- index optical fiber- general analytical approach

Chaubey, V.K. (Canadian Science Publishing, 1988)

Using a fairly rigorous approach, a general characteristic equation for a doubly clad step-index fibre has been derived under the assumption that the refractive-index difference between the inner and outer cladding is ...

Copper uptake by free and immobilized cyanobacterium

Verma, Sanjay Kumar (OUP, 1989)

Copper uptake in free and immobilized cells of the cyanobacterium Nostoc calcicola has been examined. The immobilized cells invariably maintained a higher profile of Cu intake rate (12.7 nmol mg−1 protein min−1) over the ...

Factors regulating copper uptake in a cyanobacterium

Verma, Sanjay Kumar (Springer, 1990)

Copper uptake in the diazotrophic cyanobacteriumNostoc calcicola was found to be typically biphasic, comprising rapid binding of the cations to the cell wall (during the first 10 min) followed by the subsequent ...

Genetic transformation of glutamine auxotrophy to prototrophy in the cyanobacterium Nostoc muscorum

Verma, Sanjay Kumar (Springer, 1990)

Photophysics of doubly-charged quinine: Steady state and time-dependent fluorescence

Pant, Debi D. (Elsevier, 1990-04)

The quinine dication in aqueous solution (1 N H2SO4) gives two fluorescence lifetimes (τ1 = 2.80 ns and τ2 = 19.36 ns) at ambient temperature. τ2 shows a small increase with an increase in acid concentration between 0.1 N ...

Photophysics of doubly-charged quinine: Steady state and time-dependent fluorescence

Pant, Debi D. (Elsevier, 1990-04)

The quinine dication in aqueous solution (1 N H2SO4) gives two fluorescence lifetimes (τ1 = 2.80 ns and τ2 = 19.36 ns) at ambient temperature. τ2 shows a small increase with an increase in acid concentration between 0.1 N ...

Photophysics of protonated 6-methoxyquinoline: steady state and time-dependent fluorescence

Pant, Debi D. (Elsevier, 1990-11)

Nanosecond time-resolved emission spectroscopy was used to investigate the excited state solute—solvent interaction in 6-methoxyquinoline. A red shift in the emission maximum is observed on excitation at the red edge of ...

Evidence for energy-dependent copper efflux as a mechanism of Cu2+ resistance in the cyanobacterium Nostoc calcicola

Verma, Sanjay Kumar (OUP, 1991)

Wild-type Nostoc calcicola carried out oxygenic photosynthesis extremely sensitive to copper. A Cu(2+)-resistant mutant (Cu-R1) of the cyanobacterium grew normally at high concentrations of Cu2+. Its ability to grow under ...

Parallel iterative algorithms for solving fundamental mode neutron flux distribution

Rajagopalan, Shekhar (Elsevier, 1991)

Issues relating to implementing iterative procedures, for numerical solution of neutron diffusion equations on a distributed parallel computing system, are discussed. Preliminary investigations for a reactor modelled on a ...

Excited state solvation dynamics of 6-methoxyquinoline

Pant, Debi D. (Elsevier, 1991-02)

Steady state and transient studies of 6-methoxyquinoline (6MQ) were undertaken. 6MQ undergoes a large change of dipole moment on excitation. The low energy absorption band Lb does not change in position with solvent polarity ...
