Frozen sherbets are products similar to ice cream, but differ from it by having a higher fruit acid content, a much lower overrun, a higher sugar content between 25 and 35% which gives a lower melting point, a coarser texture, a greater cooling characteristic while being consumed and an apparent lack of richness due to lower milk solids content. Keeping in view the demand of these products in summer, a technology was developed for the manufacture of orange-flavored frozen sherbet. The effect of various ingredients like squash level, milk, sugar, stabilizer, emulsifier and citric acid level was studied and their levels optimized. The optimized parameters for orange frozen sherbet were (for a four-litre batch): orange squash 500 gm, milk 1.5 lit, sugar 650 gm, sodium alginate 8.5 gm, GMS 5 gm and citric acid 7.5 gm. The method of preparation included selection of ingredients, mixing of milk, squash, stabilizer, citric acid and emulsifiers in a vessel, heating the mix to 80°C, cooling to about 5°C, ageing the mix at 5°C for 24hrs, freezing the aged mix in a batch freezer to a freezing point of about -5°C, packing in 100 ml capacity polystyrene cups and hardening at – 15°C.

The effect of low molecular weight plasticizer on the properties of Na⁺ ion conducting PEO/PVP blended solid polymer electrolyte (SPE) membranes, 95[35PEO:35PVP:30NaF]: 5x, where x = PEG₂₀₀, PEG₄₀₀, PEG₆₀₀were reported. SPE films were prepared using solution cast technique. The solid polymer electrolyte film, (35PEO:35PVP:30NaF), also prepared and identified as the highest conducting composition at room temperature. Complexation of the prepared electrolytes was studied by X-ray diffraction (XRD) analysis. The optical behaviour of the SPE films was studied from ultraviolet-visible (UV-vis) spectroscopy, and the optical parameters viz. absorption edge, direct energy bandgap and indirect energy band gap were determined. Frequency dependent conductivity (σ_ac) values were obtained from complex impedance (cole-cole) plots. It was observed that the magnitude of conductivity increased with the decrease of molecular weight of the plasticizer at room temperature. The charge transport mechanism in this SPE is mainly due to ions which were confirmed by the transference number experiment. Using this electrolyte, cells were fabricated and their discharge profiles were studied under constant load. Several cell parameters associated with the cells were evaluated.

The simulations are conducted in WRF mesoscale model by choosing the two-way interaction option, so that the information of outer domain of grid spacing with 18 km horizontal resolution can influence the atmospheric systems that occur in the innermost domain of grid spacing 2km horizontal resolution. The features of sea breeze circulation are discussed using air temperature, wind direction and wind speed observed at surface (about 10 m) level. The analysis was carried out considering non-rainy days in the representative months of April and May.
