Prediction of Coastal Hydrodynamics Quarantined in the Sediments With Utility of Textural Characteristics and Magnetic Susceptibility of Jagatsinghpur Coast, Odhisa District, India

Abstract This current research aims to perceive depositional energy environment of jagatsinghpur coastal area sediments with outcome of Textural aspects of particle size dissemination and Magnetic susceptibility (MS). In study, 36 sediment samples recovered from 12 locations with 3 points such as Low Tide (LT), High Tide (HT), and Berm (BM) along with every 5 km interval. To observe outcome from different parameters such as Mean (MQ), Standard deviation (SD), Skewness (SK) &amp; Kurtosis (KU), bivariate plots, and MS methods were adopted. From the outcome, the MQ and SD of LT, HT and BM infer medium sand to fine sand with a moderately sorted to well-sorted nature as well as SK and KU of LT, HT and BM infer extreme coarser skewed to fine skewed with platykurtic to extreme leptokurtic nature. Textural parameters shows the Southern Part of the study area experienced the low energy condition. Mainly, the energy process plot indicates sediments fall in the inner shelf and river environment. CM plot expressed the sediment samples reacted as graded suspension and rolling mechanism. The MS of low frequency, the higher quantity of magnetic contents of 3 zones low tide (LT), high tide (HT), and berm (BM) has been 62.57 x10− 8 m3 kg− 3, 72.83 x10− 8 m3 kg− 3 and 454.63 x10− 8 m3 kg− 3. The Pearson’s Correlation signifies the + ve relationship between Berm low frequency vs Berm Mean, low tide means (r2 = 0.57, (r2 = 0.40) signifies the multi-source of sediment deposition. From the output, the northern part of study infers high energy environment.</jats:p

Adiabatic CMOS-Based Electrostatic MEMS Actuation for Reduced Dynamic Power and Switching Activity

The basic purpose of MEMS actuation is to miniaturize the actuators and sensors for applications in nanoelectronics. The transistor switching current and power supply noises due to voltage drops across the metal lines can impair circuit timing and performance, posing a continuing problem for high-performance chip designers. This work presents an empirical concept of a reconfigurable charge pump based on FPGA for electrostatic actuation of the Microelectromechanical System (MEMS). The goal of the design is to produce enough on-chip voltages for actuating the MEMS that are continuously adaptive and reconfigurable. In this proposed method, pumping capacitors lying in the range of 1-pF have been deployed to decrease the area of design concerned. The various voltages are programmable digitally and created by dynamically altering the number of phases as well as the clock drive levels. The dynamic model is designed by adjusting the number of stages to produce on-chip voltages including clock drive speeds, assuming a purely capacitive load. The proposed model’s power consumption can be lowered in the steady state by lowering its clock frequency and electrostatic MEMS actuators with capacitive load. An average of 0.62 W is dissipated by the circuit when the eight stages are triggered. Consequently, with adiabatic and without adiabatic architecture, 0.0186 mW of minimum power difference is obtained.</jats:p

Coconut reinvented: Development of a high-value functional product from the ‘tree of life’

This study focuses on developing and characterizing a tender coconut kernel bar as a value-added product. Coconut (Cocos nucifera L.), known as "Kalpavriksha" or "tree of a thousand uses," is a significant crop in tropical regions, with India ranking as the third-largest producer worldwide after Indonesia and Philippines, producing approximately 11.4 million tons annually. The research aimed to standardize technology for converting tender coconut kernel, which often goes to waste after the consumption of tender coconut water, into a nutritious bar, addressing economic risks faced by coconut growers due to price fluctuations. The production methodology involved extracting and processing coconut pulp from 8-9 months maturity coconuts sourced from Tamil Nadu Agricultural University, incorporating ingredients including sugar (50 %), corn flour (25 g), rice flour (25 g) and citric acid (10 g). The mixture was cooked to 50 °Brix, poured into aluminium trays and dried at 60 °C for 12 hrs before cutting and packaging in silver-laminated aluminium packaging. Nutritional analysis revealed that the fresh kernel contained 50 % moisture, 4 % protein, 10 % carbohydrates and 2 % crude fiber. The finished product contained 19.67 % moisture, 2.45 % protein, 0.96 % crude fiber and 1.23 % ash, with a pH of 5.21. Mineral analysis using ICP-OES revealed significant amounts of potassium (2672.19 ppm), calcium (316.03 ppm), magnesium (298.97 ppm) and iron (162.68 ppm). Sensory evaluation using a 9-point hedonic scale showed high consumer acceptability with an overall score of 7.9. The product maintained stable sensory characteristics during three months of refrigerated storage. This innovation provides an effective solution for tender coconut kernel utilization while creating a nutritious snack alternative with functional health benefits, contributing to the economic sustainability of coconut cultivation through value addition
