PvcABCD are cluster of genes found in Pseudomonas aeruginosa. The research was designed to examine the relationship between the pvc genes expression and cupB gene, which plays a crucial role in the development of biofilm, and rhlR, which regulates the expression of biofilm-related genes, and to investigate whether the pvc genes form one or two operons. The aims were achieved by employing qRT-PCR technique to measure the gene expression of genes of interest. It was found that out of 25 clinical isolates, 21 isolates were qualified as P.aeruginosa. Amongst, 18(85.7%) were evaluated as biofilm producers, 10 (47.6%), 5 (23.8%), and 3 (14.2%) were evaluated as strong, moderate and weak producers respectively, while, 3 (14.2%) were considered as a non-biofilm forming isolate. The pvcA and pvcB were shown to be over-expressed (>2) fold in all biofilm-producer isolates, similar to that observed in cupB and rhlR, while pvcC and pvcD showed to be down-regulated (<0.5) fold in these isolates. These findings imply that the pvc genes are organized into two operons, pvcAB, and pvcCD, and genes involved in biofilm formation are regulated by pvcAB operon. This is the first study in Iraq to investigate these genes.

Advantage of the science of management for a lot of other sciences vitality and openness to the rest of the science and knowledge of the various branches fields, and at the same time, overlapping and intermingling majora between the various branches of administration and specialties, and based on this fact, the idea of this research to come out of one of the important topics with two topics of vital in the field of strategic management, namely patterns Strategic Command, and the effectiveness of senior management teams. I've seen the science of management, particularly in the field of strategic management, large shifts and changes, especially in the last two decades, as the RPR Strategic Management rich field of research and the emergenc

The research aimed at measuring the degree to which the accept their class environment in governmental & civil Kindergartens & it also aimed at knowing the differences between the dimensions of the measurement & the differences according to the kindergarten & class variables .
The researcher made a measurement for the class environment & it included five dimensions & the answering choices were three ( to a big extent , to some extent and no ) and after making sure that the measurement is usable , the researcher applied it on the sample which consisted of ( 212 )male & female children through the estimated answers of the teacher & the result was that there was an accep
