Background :Older adults with cerebrovascular accident (CVA) show evidence of auditory and speech perception problems. In present study, it was examined whether these problems are due to impairments of concurrent auditory segregation procedure which is the basic level of auditory scene analysis and auditory organization in auditory scenes with competing sounds.   Methods : Concurrent auditory...

BACKGROUND AmpC type β-lactamases are commonly isolated from extended-spectrum Cephalosporin-resistant Gram-negative bacteria. Also, resistance appeared in bacterial species not naturally producing AmpC enzymes. Therefore, a standard test for the detection of the plasmid-mediated AmpC enzyme and new breakpoints for extended spectrum Cephalosporins are urgently necessary. OBJECTIVES To detect ...

DNA damage tolerance (DDT) is a cell function to avoid replication arrest by DNA damage during DNA replication. DDT includes two pathways, translesion DNA synthesis (TLS) and template-switched DNA synthesis (TS). DDT is regulated by ubiquitination of proliferating cell nuclear antigen that binds to double-stranded DNA and functions as scaffold protein for DNA metabolism. TLS is transient DNA sy...

Objectives: All subjects suspected of Central Auditory Processing Disorder (CAPD) were previously tested by free recall dichotic digits test (DDT). The study objective was normalization and reliability evaluation of two-pair DDT in 750 native Persian subjects aged 8 to 12 years. Materials: A total of 750 subjects were divided into five age groups varying between 8 years and 12 years and 11 mon...

This paper proposes an inter-frame dynamic double threshold (IF-DDT) spectrum sensing algorithm in order to improve the sensing performance based on energy detection (ED) in cognitive radios (CRs). Based on both the activity model of the primary user (PU) and the sensing mechanism of the secondary user (SU), the proposed algorithm exploits the relationship between two adjacent sensing frames an...

background and objective: reliable methods of detection of antimicrobial resistance are of paramount importance in the treatment and management of infections caused by coagulase negative staphylococci (cons). the objective of the present study was to compare and evaluate the performance of disc diffusion and e test (epsilometer test) methods for antimicrobial testing of coagulase negative staph...

background : according to the national strategy plan on monitoring of insecticides resistance, this study was carried out to determine the base line susceptibility of the culicidae mosquitoes to the who-recommended insecticides in an endemic focus of malaria in southeastern iran. methods : larval collection was carried out by dipping method and adult collection occurred by suction tube from jan...

I model profiles of the [Ne ii] forbidden emission line at 12.81μm, emitted by photoevaporative winds from discs around young, solar-mass stars. The predicted line luminosities (∼ 10L⊙) are consistent with recent data, and the line profiles vary significantly with disc inclination. Edge-on discs show broad (30–40 km s−1) double-peaked profiles, due to the rotation of the disc, while in face-on ...

ESBLs are now a problem in hospitalized patients throughout the world. The prevalence of ESBLs among clinical isola tes varies greatly worldwide and in geographic areas and are rapidly changing over time. A total of 81 isolates of Enterobacteriaceae ESBLS, have been chosen in order to confirm ESBL-producing isolates, this confirmation was done by inhibitor potentiated disc diffusion test. Of th...

The Double Decker Turbine (DDT) is a recent design introduced for oscillating water column (OWC) devices. Its major contribution the combination of two typical solutions in just one prototype: self-rectifying performance, to deal with bidirectional flow, and twin-turbine concept, allowing use unidirectional turbines. This achieved by set concentric turbines, called external internal turbines (E...
