The Reserve Bank of India and a closely associated institution, NABARD, have undertaken a wide range of activities designed to support microfinance. However, many of these have been "developmental" initiatives of a financially repressive nature (such as directed credit requirements and refinancing of loans to priority sectors) and have not contributed to the emergence of a sustainable microfina...

Solar-assisted water electrolysis is a promising technology for storing the energy of incident solar irradiation into hydrogen as fuel. Here, an integrated continuous flow electrochemical reactor coupled to monolithic perovskite-silicon tandem cell demonstrated that provides light-driven solar-to-hydrogen conversion with efficiency exceeding 21% at 1-Sun equivalent light intensity and stable op...

We consider the relativistic spinor field theory re-formulated in polar variables so to allow for interpretation given terms of fluid variables. After that dynamics fields is converted as a special type spin fluid, we demonstrate such conversion into dynamical not unique but it can be obtained through $19$ different rearrangements, by explicitly showing minimal systems hydrodynamic equations ar...

The 4 crystal symmetry in materials such as GaAs can enable quasi-phasematching for efficient optical frequency conversion without poling, twinning or other engineered domain inversions. 4 symmetry means that a 90° rotation is equivalent to a crystallographic inversion. Therefore, when light circulates about the 4 axis, as in GaAs whispering-gallery-mode microdisks, it encounters effective doma...

Both the current corn starch to ethanol industry and the emerging lignocellulosic biofuels industry view recycling of spent fermentation broth or stillage as a method to reduce fresh water use. The objective of this study was to understand the impact of recycling stillage on conversion of corn stover to ethanol. Sugars in a dilute-acid pretreated corn stover hydrolysate were fermented to ethano...

This paper presents the design and fabrication of a feed horn antenna integrated fix-tuned 380GHz sub-harmonically pumped mixer, based on planar GaAs air-bridged Schottky anti-parallel diode from Rutherford Appleton Laboratory. The diode was designed and fabricated by millimeter technology group, Rutherford Appleton Laboratory, UK. The mixer’s circuit configuration and cavity block are realized...

Multi-valued logic (with radix. 2) can be viewed as an alternative approach to solve many problems in transmission, storage and processing of large amount of information in digital signal processing. In arithmetical operation signed digit number is very essential for carry free computation. To achieve the parallelism in computation, a suitable number system and an efficient encoding/decoding sc...

The knowledge of 1-minute integrated cumulative rain rate distribution is required for predicting the attenuation induced by rain on satellite and terrestrial microwave and millimetric links. In this paper, conversion coefficients are derived for estimating the equivalent 1minute rain rate statistics from those available in 5 and 30-minutes over Akure, South-Western Nigeria. The derivation is b...
