Enhancement in superconducting transition temperature and upper critical field of LaO0.8F0.2FeAs with antimony doping (2008)

Singh, S. J., Prakash, J., Patnaik, S., Ganguli, A. K.

We report the synthesis and characterization of antimony doped oxypnictide superconductor, LaO0.8F0.2FeAs1-xSbx (x = 0.05 and 0.10). The parent compound LaOFeAs with fluorine doping exhibits...

Superconductivity at 11.3 K induced by cobalt doping in CeOFeAs (2008)

Prakash, J., Singh, S. J., Patnaik, S., Ganguli, A. K.

Pure phases of a new oxyarsenide superconductor of the nominal composition CeOFe0.9Co0.1As was successfully synthesized by solid state reaction in sealed silica ampoules at 1180 C. It crystallizes in...

Potassium fluoride doped LaOFeAs multiband superconductors: Evidence for extremely high upper critical field (2008)

Singh, S., Prakash, J., Srikala, D., Singh, A. K., Patnaik, S., Ganguli, A. K.

We describe a new methodology of synthesizing the oxypnictide superconductors with potassium fluoride as a source as a source of fluorine instead of LaF3. This route also allows the substitution of...

Magnetic effect on oscillatory blood flow in a constricted tube (2004)

Prakash, J, Makinde, OD, Ogulu, A

The paper considers the oscillatory flow of a Newtonian fluid in an artery with a mild stenosis. Invoking the slip boundary condition for the velocity, closed form analytical solutions have been...

On the Scattering Properties of Urban and Maritime Aerosols and its Humidity (2004)

Verma, T.S., Prakash, J.

The scattering properties of aerosols play a dominant role in radiative energy transfer and consequently influencing the visibility and turbidity in the atmosphere. In the present attempt,...

Modeling Joint Effects of Mixtures of Chemicals on Microorganisms Using Quantitative Structure Activity Relationship Techniques. Phase 3. (1998)

Nirmalakhandan, N., Arulgnanendran, V. R., Prakash, J., Sun, B., Peace, J.

A laboratory procedure was developed to measure the toxicity of 35 organic chemicals in the soil medium using the respirometeric technique. These toxicity assays were carried out using a commercially...

Transient analysis of a triangular built-in-storage solar water heater under winter conditions (1994)

Kaushik, S C, Rakesh Kumar, Garg, H P, Prakash, J

In this paper, the performance of a triangular built-in-storage solar water heater under winter conditions has been studied. The triangular cross-section of the system results in higher solar gain...

Performance prediction for a triangular built-in-storage-type solar water heater with transparent insulation (1994)

Prakash, J, Kaushik, S C, R Kumar, Garg, H P

In this paper, the design of a triangular built-in storage-type solar water heater with transparent insulation on the top and sides is studied under various operating conditions. The transient...

Solar thermal systems with transparent insulation (1992)

Prakash, J, Garg, H P, Jha, Ranjana, Hrishikesan, D S

In this paper, theoretical models are formulated to predict the thermal behaviour of various solar systems, viz. shallow solar pond water heater, built-in-storage type solar water heater, isolated...

Study of thermal performance of a black liquid shallow solar pond under various operating conditions (1989)

Verma, R, Prakash, J, Garg, H P

A black liquid solar collector cum storage system is studied. The liquid, being black, absorbs most of the radiation; also there is little reflection loss from the water surface. The performance of...

OPTICALLY STIMULATED POLARIZATION OF S---VACANCY DIPOLES IN KI (1976)

Prakash, J., Fischer, F.

The KI : S-- system has three absorption bands. By irradiation into the two short wavelength bands in the UV, a photochemical reaction occurs. The decomposition of S---vacancy dipoles and the...

A study of the environmental aerosol deposition on the plant leaves in Gaborone, Botswana (1970)

Verma, T. S., Prakash, J., Thomas, T. A.

The present experimental study was conducted to monitor the aerosol deposition on plant leaves, when exposed to open atmosphere, due to biomass burning in winter months, in particular. The number...

Spectrum of renal cortical necrosis in acute renal failure in eastern India.

Prakash, J., Tripathi, K., Pandey, L. K., Sahai, S., Srivastava, P. K.

Renal cortical necrosis is an uncommon cause of acute renal failure. We report 23 cases of biopsy-proven renal cortical necrosis which constituted 6.3% (23/363) of all cases of acute renal failure...
