conclusions the results showed that e. coli isolated from patients with uti had eight virulence factors with high frequencies. moreover, these results alleged a direct connection between virulence factors and antimicrobial resistance in e. coli. results the frequency of virulence factors papc, afa, sfa/foc, fimh, hly, neuc, ibea, and iucc were 53.3%, 51.7%, 53.3%, 56.7%, 23.3%, 31.7%, 20%, and ...

Assume that i q; m; p depends only on pair-wise price di¤erences; this property can be derived from a consumer choice model with quasi-linear preferences in money. where 1 n is a vector of ones of length n: Also, assume that the FOC is su¢ cient to characterize a unique equilibrium for any symmetric cost structure. Let i m; p denote the corresponding vector specifying the probabilities over di¤...

BACKGROUND The emergence of antimicrobial resistant strains of Escherichia coli has raised considerable interest in understanding the diversity and epidemiology of E. coli infections in humans. Virulence factors of E. coli determine the specific infections caused by this microorganism. OBJECTIVES This study aimed to determine the prevalence of eight E. coli virulence factors and their associa...

The first, fully integrated, planar fiber optic platform with spectroelectrochemical capabilities, termed the electroactive fiber optic chip (EA-FOC) is presented here. Spectroelectrochemical techniques provide complementary optical and electrochemical data which are important for applications ranging from thin film characterization to advanced sensor design. To create the EA-FOC a side-polishe...

Background: Approximately 3% of women develop posttraumatic stress disorder (PTSD) after giving birth, and 7.5% of pregnant women show a pathological fear of childbirth (FoC). FoC or childbirth-related PTSD during (a subsequent) pregnancy can lead to a request for an elective caesarean section as well as adverse obstetrical and neonatal outcomes. For PTSD in general, and several subtypes of spe...

This paper presents a comparative study of two most popular control strategies for Induction motor (IM) drives: FieldOriented Control (FOC) and Direct Torque Control (DTC). The comparison is based on various criteria including basic control characteristics, dynamic performance, and implementation complexity. The study is done by simulation using the Simulink Power System Block set that allows a...

Finite Fibonomial Operator Calculus (FFOC) is a special case of Extented Finite Operator Calculus (FOC). The ”Calculus of Sequences” was started by Ward in 1936 [1] and considered by many authors after him. The very foundations of FOC were given by O.V.Viskov, G. Markowsky and finally by the author of [8, 2, 3] . The idea of FFOC due to A.K.Kwaśniewski [2] (see Example 2.1) is now continued [4]...

In this paper, a flexible, high computation speed and cost effective field programmable gate array (FPGA)-based speed controller for an induction motor with field-oriented control, (FOC) is presented. All the control functions including the space vector modulation based PWM waveform generation, field-oriented control algorithm and rotor flux position estimation have been realized using FPGA to ...

1This paper presents a new speed observer for high performance FOC (Field Oriented Control) and DTC (Direct Torque Control) induction motor drives. It is an MRAS (Model Reference Adaptive Systems) observer which employs a linear ANN (Artificial Neural Network) for the estimation of both the rotor speed and the flux-linkage. The training of the ANN based adaptive model of the MRAS observer is pe...

<p style='text-indent:20px;'>The approximation of the fractional-order controller (FOC) has already been recognized as a distinguished field research in literature system and control. In this paper, two-step design approach is presented to realize proportional integral (FOPI) for class plant model. The goals are based on some frequency domain specifications. first stage work focused devel...
