Oxygenated chalcones (3a,b) and bischalcones (4a-j) have been synthesized and evaluated for antimalarial activity against chloroquine sensitive and resistant strains of Plasmodium berghei in mice. Some of the screened compounds, 3a, 4c, 4e, 4f and 4i, have shown significant activity at 100 mg/kg dose against sensitive strain.
The DNA topoisomerase (topo) II of chloroquine-sensitive and chloroquine-resistant strains of the rodent malaria parasite P. berghei were utilized as a target for testing of antimalarial compounds. Compounds belonging to the bischalcone and chalcone series significantly inhibited enzyme activity and percentage parasitaemia of chloroquine-sensitive and… (More)
The earliest electrical power systems were Distributed generation (DG) systems designed to cater to the needs of small local areas. With the development of technology driven by economies of scale, the focus shifted to centralized generation by providing electricity to remote areas through grid extension. During the last decade, there has been a paradigm… (More)
An innovative approach to the one-pot synthesis of highly functionalized 3,4-dihydro-1H-isothiochromenes (3), 6H-benzo[c]thiochromenes (5, 6), 6H-benzo[c]chromenes (8), and 2,3-dihydro-1-benzothiophenes (10, 11) is delineated from the reaction of a suitably functionalized 6-aryl-3-carbomethoxy-4-methylthio-2H-pyran-2-one (1) and a carbanion generated from… (More)
This paper presents a novel vehicle platoon control algorithm using Vehicle to Vehicle (V2V) and Vehicle to Infrastructure (V2I) wireless communications between platoon members. A platoon forms a chain of vehicles (e.g., trucks) for improved traffic and fuel efficiency. Platooning algorithms aim to maintain small inter-vehicular distance between vehicles… (More)
This study presents different control strategies for standalone and grid connected Photovoltaic Systems (PVS) and comparison of these different strategies has been done. This paper is intended to choose an efficient control strategy for standalone and grid connected PVS.
For improving dynamic response of grid connected photovoltaic systems voltage source inverter are operating in inner voltage and current control loop. This paper presents, a control technique for three phase grid connected photovoltaic system. Two stage power conditioning units has been used for system interfacing. First stage comprises of DC/DC converter… (More)
Induction motors are the workhorses of industries. Indirect vector control scheme has been preferred due to its superior dynamic performance. Since the conventional PI controller has bounded operating limits and poor transient response, a search for an alternative controller arises. Recently, Artificial Neural Network (ANN) is gaining momentum as a… (More)
