this study sought to examine the effect of cooperative game on iranian students achievements in english alphabet learning. cooperative games are games, in which players or teams work together towards a common goal without defeating someone. the methodology used in this study was experimental. the population of the study was 60 female students from the grade one in secondary school in tabriz, ir...
Objective: To compare the accuracy of disk diffusion method and E-test for the detection of methicillin resistance and low-level methicillin-resistance in Staphylococcus aureus (S. aureus) and the PBP2a latex agglutination test for confirmation. Materials and Methods: A total of 76 methicillin resistant S. aureus (MRSA) isolates from different clinical specimens were tested by disk diffusion me...
Background & Aims: The production of extended-spectrum-β-lactamases (ESBLs) is the main mechanism of resistance to β-lactam antibiotics. The outbreak of isolates simultaneously possessing several resistance mechanisms to β-lactam antibiotics caused a decrease in sensitivity of the confirmatory tests for ESBL. The aim of this study was the evaluation of the β-lactamase disk test method in the de...
The aim of this work was WC distribution in base Al-Si-Mg (A356) alloy as reinforcing agent. WC Solid particles in the sub-23-nm size range added to melted alloy by centrifuge casting. The cylinder tube without gap was obtained. FESEM and OPM results show that the distribution depends upon the rotational speeds of the mould and centrifugal casting conditions. According to the MAP results, durin...
abstract the present study tried to investigate the effect of visual aids (films) on the development of the speech act of disagreement among iranian efl intermediate learners. to this end, the researcher selected 40 homogeneous intermediate learners based on their scores on oxford placement test. .the subjects then divided into control group and experimental group. both classes were tested by ...
abstract the current research tried to examine the impact of multiple intelligence (mi) and its components on multiple choice (mc) and open ended (oe) reading comprehension tests. ninety six students of high school in grade four took part in this study. to collect data, participants completed multiple intelligence (mi) questionnaires along with a multiple choice (mc) and open ended (oe) forms ...
Background: A bonded fixed retainer is used to stabilize the alignment of teeth. Different composites have been introduced for this purpose. This study aimed investigate wear resistance flowable nanocomposite in comparison with microhybrid composite an vitro situation. Materials and Methods: In study, 46 disk‑shaped specimens were divided into two groups: Filtek Ultimate Z250 composite. The sam...
conclusions the β-lactamase disk test is appropriately sensitive to detect esbls in mdr isolates of e. coli. background most urinary tract infections (utis) are caused by escherichia coli (e. coli) species. due to infections outbreaks of e. coli strains with multiple mechanisms of resistance to β-lactam antibiotics, the sensitivity of confirmatory tests to detect the extended spectrum β-lactama...
The resistance of Helicobacter pylori to antibiotics leaves great influence on treatment outcome. Routine antimicrobial susceptibility testing of H. pylori should be a simple, inexpensive and standardized method to be adopted. Agar and broth dilution techniques are difficult to perform and not practical. E-test and disk diffusion methods have the advantage of allowing the visualization of resis...
in this thesis, using concepts of wavelets theory some methods of the solving optimal control problems (ocps). governed by time-delay systems is investigated. this thesis contains two parts. first, the method of obtaining of the ocps in time delay systems by linear legendre multiwavelets is presented. the main advantage of the meth...
