Change in chemical constituents and overall acceptability of frozen and dehydrated Aonla fruit pulp during storage

Ascorbic acid and total phenol in frozen aonla pulp on zero day of storage was found to be 365.5 mg/100g and 2.1 mg/g while in dehydrated aonla pulp it was 2.3 mg/100mg and 14.7 mg/g which was found to decrease with the increase in storage duration. However, significant increase (CD at 5% Level) in total soluble solids (TSS) and non-enzymatic browning was noticed with the advancement in storage duration. The decrease and increase in physico-chemical characteristics were more significant in dehydrated aonla pulp as compared to frozen aonla pulp. Mean score for sensory attributes of dehydrated aonla pulp at zero month of storage was fairly less than frozen aonla pulp. Moreover, there was more significant decrease in value of sensory attributes of dehydrated aonla pulp during six months storage period compared to frozen aonla pulp. Thus, present study was first in its kind to determine and compare chemical composition and overall acceptability of frozen and dehydrated aonla pulp obtained from aonla fruits cv. Chakaiya during storage for optimizing there use in further development of value added aonla product

Moth Search Optimization for Optimal DERs Integration in Conjunction to OLTC Tap Operations in Distribution Systems

In this paper, a newly developed moth search optimization (MSO) technique is introduced to solve the complex distributed energy resources (DER) integration problems of distribution systems. In order to overcome some of the limitations observed in the standard variant of MSO, minor corrections are also suggested. On the other hand, a new optimization problem is formulated for optimal deployment of dispatchable distributed generations and shunt capacitors while simultaneously optimizing the tap positions of on-load tap-changing transformers, already deployed in grid substations. The objective of this work is to minimize the cost of annual energy loss and node voltage deviations over multiple load levels. The proposed model is implemented and solved for two benchmark test distribution networks of 33 and 118 buses. The suggested corrections are also validated by comparing the performance of the proposed approach with standard MSO and other available optimization methods. The simulation results show that the developed model optimally utilizes the existing distribution system resources and generates higher deployment benefits at lesser DER penetration as compared to the planning model which ignores these resources

Analysis of Drop Out and Load Current for on Chip Voltage Regulators

LDO (Low Drop-Out) Voltage regulators are commonly used in electronics power supply circuit. DC linear voltage regulator is a LDO regulator that can regulate the output voltage even when the power supply voltage is very near to the output voltage. This paper present a comparison between two of the most admired voltage regulator structures such as feed forward ripple cancellation technique and MOS capacitor compensation technique.The comparison has been carried out considering the output voltage, power consumption, drop-out voltage, load current, quiescent current, line regulation and load regulation. The discussion is supported by practical analysis of both the voltage regulator. The two LDO voltage regulators are taken with power supply voltage, reference voltage, error amplifier, pass transistor. The object of this paper is to compare the all the parameter of the voltage regulator to found best LDO voltage regulator structure. The comparison showed that the voltage regulator circuit with MOS capacitor compensation technique (MCC) is best rather than feed forward ripple cancellation technique (FFRC).All simula-tion and result of LDO voltage regulator is done at tanner tool 14.1

The considered WBAN model is served for healthcare service in order to mitigate the undesired effects of WBAN due to high path loss and fading as well as to keep a low transmit power while meeting to the desired WBAN quality of services

Effect of storage temperature and duration on sugar content and sensory acceptability of strawberry pulp

Experiment was conducted to study the effect of different treatments on preservation of strawberry pulp at ambient and low storage temperature condition. The samples were pasteurized at 100°C for 15 minutes (T1), sodium benzoate 250 ppm (T2) and sodium benzoate 500 ppm (T3). The respective samples were stored for two months at room (25±5°C) and low (7±2°C) temperature conditions and reducing sugars; total sugar and sensory evaluation were recorded at three days of interval period. The results showed that the total sugar (%) increased in pulp sample maximum in T6 (5.9%) and minimum in T1 (4.8%), the maximum value regarding reducing sugars was recorded in T6 (4.9%) and minimum in T1 (1.4%) after 60th days of storage. However, reducing sugars and total sugar decreased in the stored pulp at room temperature and spoiled completely on 18th day of storage. The acceptability of organoleptic score decrease with the duration of storage in both ambient and low temperature. Among different treatments, sodium benzoate @ 500 ppm was found most effective and maintained the qualitative characteristics of preserved pulp at low (7±2°C) temperature condition. In future, these experimental results may prove very useful for storage of strawberry pulp for longer duration in better quality

Performance characteristic of sustainable ternary cements

Cement production leads to an emission of approximately 0.87 ton of CO2 for each ton of cement produced, which accounts for 7-8% of global CO2 emissions. To minimize these emissions, various alternative materials or waste products from other industries having pozzolanic or cementitious properties are used. Development of blended cement consisting of Portland cement along with two different SCMs (Supplementary cementitious Materials) has been increased in past two decades. Use of combination of Slag-Fly Ash and Calcined Clay-Limestone based Portland cement has increased in recent times. In the view of the above, present study is focused on, composite cement (Slag-Fly Ash-Portland Cement) and limestone calcined clay cement (Calcined Clay-Limestone-Portland cement), having clinker content as low as (50%). Further, concrete specimens were cast at two different water to cement ratio and various properties of concrete such as compressive strength, porosity and sorptivity were assessed. The performance of ternary cement produced by adding two different SCMs with high clinker replacement showed equivalent performance as of Portland Pozzolana Cement

Numerical Simulation of Porosity in Cements

The pores in cementitious materials, their sizes and connectivity have an important influence on the durability of concrete. Several microstructural models have been developed to simulate the three-dimensional pore network in cement pastes. In this article, microstructures with the \upmu μ ic model are compared with experimental results. It is seen that despite having a resolution for the capillary pores very close to reality, the experimentally observed breakthrough diameter from mercury intrusion is much lower than the values obtained by applying an algorithm of mercury intrusion to the simulated microstructure. The effect of some of the most important input parameters on the pore sizes in the simulated microstructure explored. The phenomenon which seems best able to explain this discrepancy is that C-S-H is not in fact a phase with a smooth surface as represented in microstructural models, but a phase which grows as needles into the pore space, leading to very small water-filled capillary pores from quite young ages. The results demonstrate it will be extremely challenging to represent the porosity of real microstructures in microstructural models on the scale of hundreds of microns necessary to study macroscopic transpor
