Tea (Camellia sinensis) Waste for the reduction of Malathion and Phorate in ...Agriculture Journal IJOEAR
Abstract— Diminution of Malathion and Phorate from aqueous solutions by tea waste biomass was examined in a batch experimental setup. Waste tea powder, obtained from University canteen, S.V. University, Tirupati, India has been used as an effective material for the reduction of Malathion and Phorate from aqueous solutions. Characterization of the adsorbent was studied using SEM micrograph and Fourier Transform Infrared spectral analysis. From the FTIR spectrum it is observed that the change in peak position at 3390 cm−1 in the spectrum of the Phorate and Malathion loaded tea powder indicates the binding of these pesticides with hydroxyl groups. The working solutions of the pesticides are in the range of 0.1µg – 1.0µg for Malathion and 0.05µg – 0.5µg for phorate. It was observed that percentage adsorption increased with pH of the liquid phase and reached an optimum value of 95 % for Malathion and 94 % for phorate at pH 7.4 ± 0.2 and pH 7.5 ± 0.2, respectively. The dosage of the adsorbent had showed considerable effect on the adsorption of Malathion and Phorate.

Optimization of Ultrasound-Assisted Extraction of Arbutin from Leaves of Pyru...IJERA Editor
Pyrus elaeagnifolia Pallas. ssp. elaeagnifolia is a medicinal plant used in traditional medicine for the treatment
of various diseases in Turkey. The leaves of Pyrus elaeagnifolia ssp. elaeagnifolia are a rich source of arbutin,
which is a naturally occurring derivative of hydroquinone. It is found in various plant species belonging to
diverse families, such as Lamiaceae, Ericaceae, Saxifragaceae and Rosaceae. It inhibits tyrosinase and has
been employed as a cosmetic skin whitening agent. In this study, Response Surface Methodology (RSM) using a
Box Behnken Design (BBD) was employed to optimize the condition for extraction of arbutin from the leaves of
Pyrus elaeagnifolia ssp. elaeagnifolia. Three influencing factors; methanol concentration, period of ultrasoundassisted
extraction and extraction temperature were investigated in the ultrasonic aqueous extraction. The
Response Surface Methodology was applied to optimize the extraction process focused on arbutin content with
respect to the above influencing factors. The best combination of each significant factor was determined by
RSM design and optimum pretreatment conditions for maximum arbutin content were established to be
methanol concentration of 48.54 %, extraction time of 39.32 min. And extraction temperature of 43.71 0C.
Under these conditions 5.37 % of arbutin content was observed experimentally, similar to the theoretical
prediction of 5.30 %.
In Ayurveda, the leaf juice of Adhatoda vasica, a shrub native to Asia is incorporated in
many traditional herbal formulations. However, suitable solvent and a suitable extraction
method for phytochemical profiling are not well established, and there is no published mass
spectra structural interpretation of the identified compounds. This has caused a few
problems in herbal formulation research due to the bias derived from different extraction
methods. Therefore, this study used polar and non polar extraction for phytochemical
analysis on Adhatoda vasica, aiming to assess the potential impact of different solvents. This
study included extractive value, total phenol and alkaloid content of the leaves in different
preparations. Gas Chromatography coupled with Mass Spectrometry (GC-MS) was used to
study the phytochemical profile of different solvents. Significant differences were observed in
all the parameters such as extract yield, total phenol, total alkaloid and phytochemical
composition. The ethanol extract stood out most for effective extraction of phytochemicals,
especially for the alkaloids. The results highlight the necessity for comparative analyses of
chemical composition in different solvent extractions and careful choice and validation of
analytical methodology in herbal formulation research.
AN OVERVIEW ON NATURAL POLYMERS AS PHARMACEUTICAL EXCIPIENTSriramNagarajan19
The use of natural excipients to deliver the bioactive agents has been hampered by the synthetic materials. However advantages offered by these natural excipients are their being non-toxic, less expensive and freely available. Excipients are any component other than the active substances intentionally added to formulation of a dosage form Research in natural polymers has witnessed growing interest and attention. This is attributable to a number of factors which include their relative abundance, low cost, and biodegrable and eco-firendly profiles. Natural polymers are basically polysaccharides so they are biocompatible and without any side effects. This review discusses various natural polymers.

Optimization of Ultrasound-Assisted Extraction of Arbutin from Leaves of Pyru...IJERA Editor
Pyrus elaeagnifolia Pallas. ssp. elaeagnifolia is a medicinal plant used in traditional medicine for the treatment
of various diseases in Turkey. The leaves of Pyrus elaeagnifolia ssp. elaeagnifolia are a rich source of arbutin,
which is a naturally occurring derivative of hydroquinone. It is found in various plant species belonging to
diverse families, such as Lamiaceae, Ericaceae, Saxifragaceae and Rosaceae. It inhibits tyrosinase and has
been employed as a cosmetic skin whitening agent. In this study, Response Surface Methodology (RSM) using a
Box Behnken Design (BBD) was employed to optimize the condition for extraction of arbutin from the leaves of
Pyrus elaeagnifolia ssp. elaeagnifolia. Three influencing factors; methanol concentration, period of ultrasoundassisted
extraction and extraction temperature were investigated in the ultrasonic aqueous extraction. The
Response Surface Methodology was applied to optimize the extraction process focused on arbutin content with
respect to the above influencing factors. The best combination of each significant factor was determined by
RSM design and optimum pretreatment conditions for maximum arbutin content were established to be
methanol concentration of 48.54 %, extraction time of 39.32 min. And extraction temperature of 43.71 0C.
Under these conditions 5.37 % of arbutin content was observed experimentally, similar to the theoretical
prediction of 5.30 %.
Standardization of punica granatum explant and callus induction through micro...eSAT Journals
Abstract Pomegranate (Punica granatum L.) and variety name ‘Bhagwa’ is an ancient, important fruit crop in India and in subtropical countries of the world as it possess various pharmaceutical and therapeutic properties. This is subjected to bacterial blight caused by Xanthomonas axonopodis pv causing a huge loss of about 50-100% in production. In order to develop a disease resistant pomegranate variety, micro propagation is necessary. The different explants such as leaves, nodes, apical shoot and petals were selected. The explants were passed through surface sterilization process and found that the mortality rate was least with the apical shoots as explants when compared to other explants. Callus Initiation was done with several treatments and the percentage of callus growth was identified using one way ANOVA by which variance was tested using Fischer’s F test and LS (Least Squares) means by Duncan’s multiple range test which proved that the LS means was higher for all the explants those undergone MS + Sucrose (30g/l) + Adenine sulfate – 40mg/l + 6BAP – 5 mg/l treatment, specifically apical shoot explants showed 92% callus growth than other explants. The elimination of polyphenol exudation was successful with silver nitrate of 5 mg/l which eradicated the browning of the tissues and paved way for the regeneration of the shoots. Key Words: Bhagwa, Micropropagation, Apical shoots, Callus induction, ANOVA, Duncan’s test, Polyphenol exudation

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
