The aim of this study was to investigate the practical utility of endocervicoscopy and targeted biopsy in high-risk human papilloma virus-positive women with abnormal squamous cells on cervical cytology and unsatisfactory colposcopy with nonvisible squamocolumnar junction. Seventy-seven high-risk human papilloma virus-positive patients with abnormal cervical cytology for squamous cells bearing ...

five-zone simulating moving bed (smb) system, designed for ternary separation, is a modified form of standard four-zone smb which is only effective in binary separation. it was reported in literature that the five-zone smb separates the extract-ii stream with a lower purity value than that of raffinate and extract-i streams. to address this issue, five zone smb was designed, using safety margin...

Application programmers increasingly prefer distributed stor-age systems with strong consistency and distributed transac-tions (e.g., Google’s Spanner) for their strong guarantees andease of use. Unfortunately, existing transactional storage sys-tems are expensive to use – in part because they require costlyreplication protocols, like Paxos, for fault tolerance. In thisp...
OBJECTIVE We intended to calculate approximate fetal doses in pregnant women who underwent diagnostic radiology procedures and to evaluate the safety of their pregnancies. MATERIALS AND METHODS We contacted hospitals in different cities in Turkey where requests for fetal dose calculation are usually sent. Fetal radiation exposure was calculated for 304 cases in 218 pregnant women with gestati...

Abstract Background: Transcranial Doppler ultrasonography results have not been previously studied in among Iranian sickle cell anemia patients. The present study was performed to evaluate the pattern of intracranial flow velocities among Iranian children with sickle cell anemia and the hematological parameters that can affect the time-averaged mean of maximum velocity in major intracranial...
