Stool samples were examined from 30 preterm neonates admitted to a nursery ward; 16 neonates had diarrhea, 12 constituted an age-matched control group without diarrhea, and 2 had an unknown history regarding diarrhea. Variable numbers of enteropathogenic Escherichia coli serotype O111:HNT strains possessing the gene coding for the enteroadherence factor (EAF) were found in stool samples from 13...

Carpolobia lutea leaves (CLL) (Polygalaceae) were earlier screened and the antiulcer ethnomedicinal claim established. This article seeks to quantitatively isolate, elucidate the active compounds from most active CLL fraction. Fractionation was by semi-preparative HPLC; the active fraction was subjected to radical scavenging assays (RSA) and quantification of the total phenolic content (TPC) we...

Using the FACTS controllers, such as static synchronous compensator (STATCOM), as it provides continuous reactive power, in the grid including wind turbine (WT) equipped with doubly fed induction generator, for improving voltage profile (under normal circumstances) and providing a transition ability from inductor generator transition state has been proposed. In this paper, in order to contr...

Reactive power as a utility of ancillary service in restructured environment is supplied by Independent System Operator (ISO). Due to the particular importance of optimal pricing strategy in the power market, the study aims to investigate this problem more closely. To this end, first the problems of restructuring, reactive power generation and its associated costs thereof were reviewed and diff...

A static VAR compensator (SVC) is a critical component for reactive power compensation in electric arc furnaces (EAFs) that used to relieve the flicker impacts and maintain voltage level. weak profile can not only reduce power-quality services, but also result system instability severe cases. The cybersecurity of EAFs becoming significant concern due their cyber-physical structure. reliance SVC...

Granuloma faciale (GF) is an uncommon inflammatory dermatosis that usually presents on the face as reddish brown or violaceous papules and nodules that may coalesce into plaques. Eosinophilic angiocentric fibrosis (EAF) is a rare fibrosing condition that shares many histologic characteristics with GF and is regarded by some authors as a mucosal counterpart of GF. We present a case of GF with co...

This paper addresses the bidding problem faced by a virtual power plant (VPP) in energy, spinning reserve service, and reactive power service market simultaneously. Therefore, a non-equilibrium model based on security constraints price-based unit commitment (SCPBUC), which is take into account the supply-demand balancing and security constraints of VPP, is proposed. By the presented model, VPP ...

Voltage flicker problems have long existed in several of the distribution areas served by the Taiwan Power Company. In the past, those research results indicating that the estimated 10 V Δ value based on the conventional method is significantly smaller than the survey value. This paper is used to study the relationship between the voltage flicker problems and harmonic power variation for the po...

BACKGROUND Liver is the primary metabolizing site of body and is prone to damage by exogenous as well as endogenous intoxicants. Polycyclic aromatic hydrocarbons such as 7, 12- dimethylbenz(α)anthracene (DMBA) is an exogenous hepatotoxin, which is well known for modulating phase I, II and anti-oxidative enzymes of liver. Plants contain plethora of polyphenolic compounds which can reverse the da...
