Although repertory grid analysis (RGA) was originally developed in clinical psychology, the technique has been adapted for use in a diverse range of fields. However, the technique is rarely addressed in marketing research texts and has not been fully utilised in the tourism literature. Also, RGA applications have predominantly been reported in the form of personal interviews. The paper reports ...

In this paper, a real-valued genetic algorithm (RGA) and a particle swarm optimization (PSO) algorithm with a new fitness function method are proposed to design a PID controller for the Automatic Voltage Regulator (AVR) system. The proposed fitness function can let the RGA and PSO algorithm search a high-quality solution effectively and improve the transient response of the controlled system. T...

background and objectives: to investigate coagulase gene polymorphisms of mrsa and mssa isolates from shiraz teaching hospitals from 2011 to 2012. materials and methods: a total of 302 isolates of staphylococcus aureus were collected from clinical specimens in three major teaching hospitals and confirmed on the basis of morphological characteristics and biochemical tests. the isolates were subj...

background: one of the limitations in the treatment of common diseases such as cancer chemotherapy is development of multidrug re sistance (mdr). polymorphisms could alter the expression level of mdr1 gene, which plays an important role in mdr. in this research, the frequency of c3435t, c1236t, and g2677t/a polymorphisms of mdr1 gene was investigated in a large group of population from hamadan ...

background: enterobacteriaceae are a large group of bacteria widely distributed in nature. escherichia coli is the most com­mon cause of urinary tract infection. two amino acid substitutions, in gyra, are commonly responsible for quinolone re­sistance in e. coli . the aim of this study was molecular survey of nalidixic acid resistance e.coli isolated from patients in the codones of 83 and 87 gy...

Coconut palms are highly susceptible to diseases caused by different pathogens, and replanting with resistant varieties is the best way to manage them. Obtaining a collection of resistance gene analogues (RGAs) is an effective strategy to identify genomic regions linked to disease resistance. We have successfully used a comparative genomics approach to amplify putative RGAs from the coconut roo...

A novel thermostable glucoamylase cDNA without starch binding domain (SBD) of Aspergillus flavus NSH9 was successfully identified, isolated, and overexpressed in Pichia pastoris GS115. The complete open reading frame of glucoamylase from Aspergillus flavus NSH9 was identified by employing PCR that encodes 493 amino acids lacking in the SBD. The first 17 amino acids were presumed to be a signal ...

The paper deals with properties of the totally distributed genetic algorithm RGA, initially designed for the PIG cellular system. We have adopted the algorithm to a mesh of processors. Simulations were performed using Transim tool in order to investigate performance of this new RGA algorithm independently of a given application. This way, characteristics such as efficiency, speedup, communicati...

Gibberellins (GAs) are a class of important phytohormones regulating a variety of physiological processes during normal plant growth and development. One of the major events during GA-mediated growth is the degradation of DELLA proteins, key negative regulators of GA signaling pathway. The stability of DELLA proteins is thought to be controlled by protein phosphorylation and dephosphorylation. ...
