the  main  clinical presentation  of  patients  with  primary antibody  deficiency (pad) incorporates upper respiratory tract infections comprising otitis media, sinusitis and pneumonia.  this  study  was  designed  to  investigate clinical and  paraclinical otological complications in major types of pad.  a cross sectional study was conducted on 55 pad patients with diagnosis of selective iga ...

Due to lack of considerations on media scalability and reuse, most selective encryption schemes previously proposed might be hard to meet challenging requirements with a certain level of security which are induced from the multi-layer based video technique, for example scalable video coding. As a reason of that, first we discuss security concerns on this issue and then analyze the existing sele...

Application-controlled congestion control and feedback serve to support latency-sensitive streaming media applications. Moving parts of the protocol processing into user space is one of the promising techniques for providing applications with the flexibility of network control. This paper presents a user-level implementation of the transport functionality to support real-time streaming media ap...

An automated, computerized system, the AutoMicrobic System, has been developed for the detection, enumeration, and identification of bacteria and yeasts in clinical specimens. The biological basis for the system resides in lyophilized, highly selective and specific media enclosed in wells of a disposable plastic cuvette; introduction of a suitable specimen rehydrates and inoculates the media in...

The coagulae-positive staphylococci comprise a very homogeneous, readily identifiable species (Evans and Niven, 1950; Shaw et al., 1951) that includes all of the proven pathogenic and enterotoxin-producing strains of staphylococci. As a result of the clinical and public health significance of these organisms, a selective medium for their isolation and enumeration would have considerable value. ...

Some 800 soil and rotten wood samples were collected from Gilan, Mazandaran and GolestanProvinces in the north of Iran. By using selective and general media, 217 Trichoderma isolates were obtained belonging to sections Longibrachiatum (69 isolates) and Pachybasium (148 isolates), respectively. Pure cultures were obtained by single conidium and single chain methods. Colony features were recorded...

Reliable identification of pathogenic Burkholderia spp. like Burkholderia mallei and Burkholderia pseudomallei in clinical samples is desirable. Three different selective media were assessed for reliability and selectivity with various Burkholderia spp. and nontarget organisms. Mast Burkholderia cepacia agar, Ashdown + gentamicin agar, and B. pseudomallei selective agar were compared. A panel o...

a new medium, termed ecol was developed for the detection and enumeration of e. coli. the selective properties of ecol medium for the detection of e.coli from mixed culture in wastewater was tested and compared with conventional coliform media at 37°c and 44°c. results clearly showed that ecol medium was enable to direct confirmation of e.coli to be carried out by the indole reaction. the resul...

Multimedia applications are becoming increasingly popular in IP networks, while in mobile networks the limited bandwidth and the higher error rate arise in spite of its popularity. These are restraining factors for mobile clients using multimedia applications such as voice over IP (VoIP) or video streaming. In some conditions the retransmission of lost and corrupted packets should increase the ...

Internet multimedia streaming is becoming increasingly popular to access multimedia information. Two major issues arise in spite of its popularity. First, limited bandwidth restricts high bit rate video transmission. Second, wireless transmission by its nature may introduce higher rate of errors during transmission. The frequent errors should cause deterioration of the quality of multimedia str...
