Influence of Blanching and Drying Air Temperature on Drying Kinetics of Banana Slices
Kumar Ravi,Pandey Om Prakash,Dhiman Sushil Kumar,Kumar Prashant 한국농업기계학회 2021 바이오시스템공학 Vol.46 No.4
Purpose Drying of agro products, analternative approach to truncate the post harvesting losses which is about 40%in case of banana as reported in literatures, is conducted for banana slicesusing tray dryer. The objective was to investigate the effect of blanching and dryingtemperature on drying kinetics of banana slices for which a comparative studyof the drying kinetics of the bananaslices under blanching and without blanching conditions was conducted. Methods The samples were made circularin shape with average diameter of 30mm and 2mm thickness. Drying was done atair velocity of 3ms-1 maintained at three different temperatures of60oC, 70oC and 80oC. Blanching of banana sliceswas done in an aqueous solution of citricacid for 1 minute. Results Comprison of blanching andwithout blancing samples was done based on drying kinetics, color, energy analysis, andcost analysis to optimize the drying conditions and reduce the process cost.Two thin layer drying models werefitted to the experimental data using nonlinear regression analysis and theresults were evaluated using statistical parameter. The significant effects ofdrying temperature, drying time and blanching on moisture content of bananaslices were analyzed by ANOVA (Analysis of Variance). Conclusions The blanchingtechnique was found as cost-effective dryingprocess as compared to the without blanching technique.

Spetroscopic ellipsometry study on electrical and elemental properties of Sb-doped ZnO thin films
Sushil Kumar Pandey,Vishnu Awasthi,Shruti Verma,Mukul Gupta,Shaibal Mukherjee 한국물리학회 2015 Current Applied Physics Vol.15 No.4
Room-temperature spectroscopic ellipsometry data has been analyzed to determine the complex dielectric functions, ε(E) = ε1(E) + iε2(E) of as-deposited Sb-doped ZnO (SZO) thin films grown on n- Si(100) substrates by dual ion beam sputtering deposition system for different growth temperatures (Tg). The dielectric functions have been obtained from ellipsometry data analyses using Cody-Lorentz oscillator in the GenOsc model. A gradual reduction in the value of electron concentration and finally the conversion of doping characteristics from donor type to acceptor type was observed with the rise in Tg. This, in turn, resulted in the decline of broadening of ε1 peaks, and hence in the increase of excitonic lifetime. Optical band-gap energy was observed to decrease with increase in Tg from 200 to 300℃, and then rise continuously with further increase in Tg. X-ray diffraction measurements showed that all SZO films had (002) preferred crystal orientation. Hall measurement and X-ray photoelectron spectroscopy analysis confirmed that the change in the electrical conduction from n-to p-type was due to the enhancement in the value of Sb5+/Sb3+ ratio and SbZn-2VZn complex formation in SZO films.

CONFORMAL HEMI-SLANT SUBMERSIONS FROM ALMOST HERMITIAN MANIFOLDS
Kumar, Sumeet,Kumar, Sushil,Pandey, Shashikant,Prasad, Rajendra Korean Mathematical Society 2020 대한수학회논문집 Vol.35 No.3
In this paper, our main objective is to introduce the notion of conformal hemi-slant submersions from almost Hermitian manifolds onto Riemannian manifolds as a generalized case of conformal anti-invariant submersions, conformal semi-invariant submersions and conformal slant submersions. We mainly focus on conformal hemi-slant submersions from Kähler manifolds. During this manner, we tend to study and investigate integrability of the distributions which are arisen from the definition of the submersions and the geometry of leaves of such distributions. Moreover, we tend to get necessary and sufficient conditions for these submersions to be totally geodesic for such manifolds. We also provide some quality examples of conformal hemi-slant submersions.
