Smart Wall Painting System

The objective of this paper is to outline a smart wall painting system for little and medium scale operations. These days robots are broadly utilized as a part of relatively every application like medicinal application, amusement, military, production lines vehicle businesses, and so on. However, the utilization of robot is as yet not generally utilized as a part of constructional work. Robots are fundamentally design to build speed and maximize accuracy of construction field work. The basic point of the paper is to design, develop and actualize Remote Operated Wall Painting Machine which helps for accomplishing painting hardware requiring little to no effort because of which the sketch work can be effectively done proficiently and in particular at extremely ostensible cost. The painting machine keeps away from coordinate contact of chemicals which can be harmful to the human painters, for example, eye, skin and respiratory system issues.. Besides that the idea of painting method that requires rehashed work time and hand rising make it physical torment, and exertion devouring. Moreover, it would offer the chance to decrease or take out human introduction to troublesome and dangerous worked system conditions, which would take care of a large portion of the issues associated with security when numerous activities happen in the meantime. This machine is is easy to operate and no need of labour required to operate effectively. At the point when development specialists and robots are appropriately coordinated in building tasks,the entire development process can be better overseen and savings in human work and timing are acquired as an outcome. wall painting is a redundant, debilitating and risky process which makes it a perfect case for automation. Painting had been mechanized in car industry however not yet for the development business. There is a strong requirement for a portable robot that can move to paint walls of buildings. In this paper, the conceptual plan of a an autonomous wall painting robot is portrayed comprising of an arm that sweeps the dividers vertically and is fitted on a versatile robot base to give the lateral feed movement to cover the painting area. The design objective is to fulfill the criteria of straight forwardness, low weight, ease and quick painting time. Ultrasonic sensors are fitted on the arm and the portable base to alter as far as possible and move in the room territory. A control system is intended to direct the arm movement and plan the versatile base movement

In vitro hepatoprotective activity of Eichhornia Crassipes flowers against CCl4 induced toxicity in BRL3A cell line

The present study was carried out to determine the in vitro hepatoprotective activity of ethanolic extract from Eichhornia crassipes (EEEC) flowers using the CCl4-challenged BRL3A cell model. Hepatoprotective activity of EEEC (at concentrations of 50, 100 and 200 μg/mL) and standard drug silymarin (200 μg/mL) was evaluated against CCl4 induced toxicity using BRL3A cell line by measuring the cell viability, aspartate aminotransferase (AST), alanine aminotransaminase (ALT), lactate dehydrogenase (LDH) leakage, lipid peroxidation (LPO) and glutathione level (GSH). Treatment with CCl4 produced a significant decrease in cell viability. In addition, hepatotoxicity was revealed by increased hepatic marker enzymes like AST, ALT and LDH paralleled with elevated lipid peroxidation and decline in GSH levels. The toxicity induced by CCl4 in the BRL3A cells was significantly recovered by treatment with EEEC. The tested doses (100 and 200 μg/mL) significantly (P <0.01) reduced the CCl4 induced elevation of AST, ALT and LDH and also restored the altered biochemical parameters. These findings provide a basis for confirming the traditional uses of E. crassipes in treating liver ailments

Unified power quality conditioner-based solar EV charging station using the GBDT–JS technique

This manuscript proposes a novel hybrid artificial intelligence (AI) approach for a unified power quality conditioner (UPQC) designed specifically for electric vehicle charging stations (EVCSs). The aim is to integrate multiple vehicle-to-grid (V2G) functionalities, thereby mitigating the challenges associated with electric vehicle (EV) grid integration and the incorporation of distributed energy resources (DERs). The hybrid technique presented in this manuscript combines the gradient boosting decision tree (GBDT) algorithm and the jellyfish search (JS) algorithm, referred to as the GBDT–JS technique. This innovative approach involves utilizing the charging station to offer EV charging services and facilitating the discharge of EVs to the power grid. Integration of the UPQC with DERs, such as photovoltaic (PV), is implemented to decrease the power rating of converters and fulfill power demand requirements. The initial converter within the UPQC is employed to manage the direct current (DC) voltage, while the second converter oversees the power charging or discharging processes of EVs. Additionally, it mitigates the impact of battery voltage fluctuations. The UPQC with vehicle-to-grid functionality minimizes the load pressure on the grid, preventing over-current issues. The presented approach regulates the UPQC converters to mitigate power quality issues such as harmonic currents and voltage sags. Subsequently, the effectiveness of this technique is demonstrated using the MATLAB/Simulink operating platform. The evaluation of GBDT–JS performance involves a comparative analysis with existing techniques. This assessment reveals that the proposed method effectively alleviates power quality issues, specifically reducing total harmonic distortion (THD), and delivers optimal outcomes

The Relationship between Population Structure and Aluminum Tolerance in Cultivated Sorghum

Background: Acid soils comprise up to 50% of the world's arable lands and in these areas aluminum (Al) toxicity impairs root growth, strongly limiting crop yield. Food security is thereby compromised in many developing countries located in tropical and subtropical regions worldwide. In sorghum, SbMATE, an Al-activated citrate transporter, underlies the Alt(SB) locus on chromosome 3 and confers Al tolerance via Al-activated root citrate release. Methodology: Population structure was studied in 254 sorghum accessions representative of the diversity present in cultivated sorghums. Al tolerance was assessed as the degree of root growth inhibition in nutrient solution containing Al. A genetic analysis based on markers flanking Alt(SB) and SbMATE expression was undertaken to assess a possible role for Alt(SB) in Al tolerant accessions. In addition, the mode of gene action was estimated concerning the Al tolerance trait. Comparisons between models that include population structure were applied to assess the importance of each subpopulation to Al tolerance. Conclusion/Significance: Six subpopulations were revealed featuring specific racial and geographic origins. Al tolerance was found to be rather rare and present primarily in guinea and to lesser extent in caudatum subpopulations. Alt(SB) was found to play a role in Al tolerance in most of the Al tolerant accessions. A striking variation was observed in the mode of gene action for the Al tolerance trait, which ranged from almost complete recessivity to near complete dominance, with a higher frequency of partially recessive sources of Al tolerance. A possible interpretation of our results concerning the origin and evolution of Al tolerance in cultivated sorghum is discussed. This study demonstrates the importance of deeply exploring the crop diversity reservoir both for a comprehensive view of the dynamics underlying the distribution and function of Al tolerance genes and to design efficient molecular breeding strategies aimed at enhancing Al tolerance.CGIAR[G3007.04]McKnight FoundationFundacao de Amparo a Pesquisa do Estado de Minas Gerais (FAPEMIG)National Council for Scientific and Technological Development (CNPq
