Background: Pseudomonas aeruginosa is a gram-negative bacillus that an opportunistic pathogen in patients with immune system disorder is known. One of the common causes of nosocomial infections is considered. Organisms oxidase positive, catalase positive, animated, and aerobic and lacks the ability to ferment carbohydrates. Group B beta-lactamase, which called MBL. Since the range generally mak...

the importance of writing as a complex skill in applied linguistics has drawn the attention of many researchers to evaluate textbooks in order to help learners gain self-sufficiency and autonomy in the field of language use and communication. investigations have shown that developments in textbooks evaluation can promote the quality of pedagogies and consequently the learning. this study attemp...

Background: Molecular DNA markers are one of the most important tools in molecular biology labs. The size of DNA molecules is determined by comparing them with known bands of markers during gel electrophoresis. There are many different protocols to produce these kinds of molecular markers. In this study we have suggested an efficient strategy to produce molecular weight markers in industrial pr...

why some learners are willing to communicate in english, concurrently others are not, has been an intensive investigation in l2 education. willingness to communicate (wtc) proposed as initiating to communicate while given a choice has recently played a crucial role in l2 learning. it was hypothesized that wtc would be associated with language learning orientations (llos) as well as social suppo...

Pseudomonas aeruginosa possesses a polar flagellum made up of flagellin subunits that encoded by fliC gene. Flagellin from several strains of P. aeruginosa on the basis of reaction with polyclonal antibodies and apparent molecular weight was divided into a or b types. Material and Methods: After extraction of the genomic DNA from two standard strains 8821M (Type a) and PAO1 (Type b) and some c...

in this study, the effects of oleothermal modification on physical and mechanical peroperties of fir wood (abeis sp.) blocks were examined. at first, some blocks of fir wood with 5 × 20 × 120 cm dimensions were prepared. the blocks were treated in soybean oil. the effects of 3 factors such as treatments temperature (180and 200 °c), holding time (12 and 15 h) and initial moisture content of wood...
