Abstract: Orthorhombic structure of rare earth perovskite type oxide (RFeO3, R =Pr, Nd) nano particles prepared by metathesis method. Powders prepared were characterized by several measurements such as X-ray diffraction, scanning electron microscope, EDX, FTIR, and diffuse reflectance spectroscopy to understand their physio-chemical properties. NdFeo3 and PrFeo3, synthesized metathesis method crystallite size of 61nm and 60.5 nm respectively.

Mung Seeds Under Constant Low Potential Difference During Post-Germination When Sprout Length Grows
A. Ghorai

Abstract: Low potential difference 𝟎.𝟎𝑽𝒐𝒍𝒕 𝟏.𝟓𝑽𝒐𝒍𝒕, 𝟑.𝟎𝑽𝒐𝒍𝒕, 𝟒.𝟓𝑽𝒐𝒍𝒕, and 𝟔.𝟎𝑽𝒐𝒍𝒕 are applied during the growth of sprout length after germination and post-germination of mung seeds in open-air conditions. The sprout length decreases with an increase in potential difference and graphs show non-linear variations. Thus, this potential difference produces a negative impact on the sprout length elongation of seeds. The decrease in the sprout length may be due to lesser diffusion through the cell wall or due to the weakening of the activity of the other cell components leading to a slower rate of cell division. This may have an impact on the process of preservation of seeds.

Keywords: Potential Difference, Seed, Germination, Sprout.

Abstract: Because of the low value of the convective heat transfer coefficient between the absorber plate and the air, the thermal efficiency of a solar air heater is greatly reduced, resulting in high absorber plate temperatures and large heat losses to the surrounding environment. The analysis of heat transmission in a solar air heater is presented in this research, which makes use of Computational Fluid Dynamics. An investigation is conducted into the effect of the Reynolds number on the Nusselt number and friction factor. It is necessary to study and visually depict the nature of the flow across the duct of a solar air heater, which is done using a commercial finite volume software. The findings of the CFD simulations are found to be in excellent agreement with the experimental results. Because of this, the average Nusselt number increases as the Reynolds number grows, and the average friction factor reduces as the Reynolds number increases as well.
