Endogenous and Exogenous Enzyme Effects on Different Breeding Clones of Sweetpotato (Ipomoea batatas Lam.) Roots Starch in Ethanol Production
Abstract: The research described herein compares ethanol yield from the conversion of starch in sweetpotato storage roots via endogenous enzyme hydrolysis to that of exogenous enzyme hydrolysis (diastatic barley malt). White-fleshed roots of sweetpotato (Ipomoea batatas Lam) breeding clones; TU090R0005, TIB4004, TU090020, TU090013, BM8342197-05, BM854219905 and TIB4085 were processed for distillation to determine ethanol concentration. HPLC analysis was used to determine ethanol and residual sugar concentrations and 1H NMR analysis was …

Potentials of Hybrid System in Powering Off-grid Macro Base Transmitter Station Site
Abstract: This paper explores the possibility of hybridizing the diesel generator source system with renewable energy sources and demonstrate the potential of renewable energies to replace (partially) diesel as a source of power for mobile base station sites. The concept of hybridizing the diesel generator is to reduce both the operating cost and the quantity of different air pollutants. The patterns of load consumption by mobile base station are studied and …

Simulation of Biomass Gasification in Downdraft Gasifier Using Aspen Plus
Abstract: Normal 0 false false false EN-US X-NONE X-NONE Generating electrical energy through biomass has advantages besides achieving self-sustainability. Biomass is particularly useful for agriculture dependent economy nations like India. Energy conversion systems based on biomass are particularly interesting because biomass utilization effectively closes the carbon cycle. A comprehensive process model is developed for biomass gasification in an atmospheric fixed bed rector using the ASPEN PLUS simulator. An original equilibrium gasification …

Non-linear Integral Equations Ideal Solar Cells Analysis with One and Two Intermediate Bands
Abstract: An innovative and groundbreaking theory is proposed by using intermediate bands within the energy gap of the semiconductor in order to increase the efficiency of solar cells. Consequently, photons with energy less than the band gap may contribute to the output device by using the intermediate band or bands, in order to jump to the conduction band. This problem is reduced to the solution of non-linear integral equations and for …
