Analysis of radiation patterns of compound box-horn antenna

Gupta, R.C.; Singh, S.P. (2007)

A new type of antenna named as compound box-horn antenna is designed and analyzed for its radiation pattern. The present analysis is based on plane wave spectra for three-dimensional fields. The compound box-horn antenna ...
Composite pre-reduced pellet quality as affected by reductant reactivity

Gupta, R.C.; Misra, S.N. (Iron and Steel Institute of Japan, 2001)

The composite pre-reduced (CPR) pellets have been developed to utilise steel plant waste fines (eg. Iron ore, flue dust, mill scale, coke, coal, lime etc.) into value added product suitable for blast furnace feed as ...
Development and analysis of a microwave direct contact water-loaded box-horn applicator for therapeutic heating of bio-medium

Gupta, R.C.; Singh, S.P. (Electromagnetics Academy, 2006)

A novel, potential and efficient microwave direct contact hyperthermia applicator referred to as water-loaded box-horn for therapeutic heating of bio-medium is designed and developed at 915 and 2450 MHz. Also, theoretical ...
DRI apparent density and its strength

Gupta, R.C.; Shaik, A.A. (2005)

The cold crushing strength (CCS) of directly reduced iron (DRI) with its apparent density was correlated. Two different types of DRI were tested which included the iron ore pellets reduced in the bed of carbonaceous ...
The Effect of Additives and Reductants on the Strength of Reduced Iron Ore Pellet

Gupta, R.C.; Gautam, J.P. (Iron and Steel Institute of Japan CODEN, 2003)

The higher strength of directly reduced iron (DRI) in pellet form is useful in handling, storing and charging from height without breakage. The DRI pellets commonly exhibit 60 kg cold crushing strength. In this work the ...
Effect of Reduction Rate on the Swelling Behaviour of Iron Ore Pellets

Sharma, T.; Gupta, R.C.; Prakash, B. (1992)

In the present investigation an attempt has been made to determine the effect of reduction rate on the swelling behaviour of iron ore pellets. For this purpose two Indian iron ore fines from Bailadila and Noamundi deposits ...
Elliptically bent conformal phased array of modified box-horns for hyperthermia treatment of tumors

Gupta, R.C.; Singh, S.P. (2007)

A novel and effective hyperthermia applicator utilizing an elliptically bent conformal phased array of modified box-horns is analyzed using Fresnel-Kirchhoff scalar diffraction field theory. This configuration is mainly ...
Fe-Cr Melt Nitrogenation When Exposed to Nitrogen Plasma

Sinha, O.P.; Gupta, R.C. (1994)

The nitrogen absorption/desorption for pure iron and Fe-C alloys have been investigated in detail in levitated melts. However, limited study seems to be made while molten Fe-Cr alloy is exposed to nitrogen plasma. Nitrogen ...
Implication of linker length on cell cytotoxicity, pharmacokinetic and toxicity profile of gemcitabine-docetaxel combinatorial dual drug conjugate

Kushwah, V.; Katiyar, S.S.; Agrawal, A.K.; Saraf, I.; Singh, I.P.; Lamprou, D.A.; Gupta, R.C. (Elsevier B.V., 2018-09-05)

The present study investigates effect of linkers [zero length (without linker), short length linker (glycine and lysine) and long length linker (PEG1000, PEG2000 and PEG3500)] on pharmacokinetics and toxicity of docetaxel ...
Note Nitrogen Absorption Rate under Plasma Arc Compared to Resistance and Induction Melting

Sinha, O.P.; Gupta, R.C. (1994)

Nitrogen Absorption Rate under Plasma Arc Comparedto Resistance and Induction Melting
Water hyacinth char addition in iron ore pellet: An exploratory study

Gupta, R.C.; Gautam, J.P.; Mohan, S. (Iron and Steel Institute of Japan, 2003)

The utilization of water hyacinth as an additive in the preparation of iron ore pellets was investigated. The prepared pellets, fired for particular time and temperature, were tested via cold crushing strength (CCS) ...
