reactive power management plays an essential role in the secure operation of the power system as an ancillary service. although in electricity markets, the particular attention is paid to active power, the reactive power also plays an important on total generation costs of electricity. on the other hand, as it is mainly confined to local consumption, to avoid market power and maintain the secur...

BACKGROUND Viola canescens Wall. ex. Roxb. exhibits analgesic, antimalarial and antispasmodic activities. It is used folklorically for the treatment of liver diseases, hypertension, malaria and cancer. The current study investigates phytochemical constituents, antioxidant and hepatoprotective activity of solvent extracts of whole plant of Viola canescens. METHODS Phytochemicals, acute toxicit...

The ethanol extract of B. javanica seed was fractionated with solvents of different polarities and tested for antioxidant activities by several assays including DPPH radical scavenging activity, ferric reducing antioxidant power (FRAP), ferrous ion chelating activity (FCA), and nitric oxide radical scavenging activity (NORSA) along with their polyphenolic contents. Antidiabetic activity was eva...

The ethanol crude extracts (ECE) and their subfractions from Zanthoxylum bungeanum leaves were prepared and their phytochemical profiles and antioxidant and antimicrobial activities were investigated. Moreover, the effective HPLC procedure for simultaneous quantification of twelve compounds in Z. bungeanum leaves was established. The correlation between the phytochemicals and antioxidant activi...

In this paper, a new structure for reactive power market is presented. Considering reactive power losses caused by active power flow in the reactive power market is the main purpose of this paper. Hence, this study tries to improve reactive power market and create fair competition in reactive power generation.

Enzyme-altered foci (EAF) develop in rat liver in response to carcinogen treatment. Our hypothesis is that EAF adapt to genotoxic stimuli by lowering their expression of p53 and that such decreased p53 expression confers a growth advantage on the hepatocytes present in EAF. After a single neonatal dose of diethylnitrosamine (DEN), rats were treated with either 2 - 12 additional doses of DEN or ...

The enhanced surface area of silicon nanotexture is an important metric for solar cell integration as it affects multiple properties including optical reflectance, dopant diffusion, and recombination. Silicon typically characterized by its surface-area-to-projected-area ratio or factor (EAF). However, traditional approaches measuring EAF provide limited statistics, making correlation studies di...

Electric arc furnace (EAF) steel slag filters were investigated for their efficiency at reducing the concentration of phosphorus (P) from dairy farm wastewater in Vermont. The primary objective for this study was to examine the use of in series design on filters’ performance in P removal from dairy farm wastewater at subzero temperatures. Other research objectives were to investigate operationa...

The enteropathogenic Escherichia coli adherence factor (EAF) probe detects isolates of enteropathogenic E. coli that exhibit localized adherence to HEp-2 cells. A 21-base oligonucleotide probe was constructed on the basis of a sequence from within the 1-kb EAF probe and was shown to have greater sensitivity and specificity than the EAF fragment probe in detecting localized adherent E. coli.
