Background: In recent years, many reports have investigated the usefulness of brachial artery blood flow (BAF) measured by ultrasonography as an evaluation index for vascular access (VA) stenosis hemodialysis patients. However, mechanism VA dysfunction, despite BAF being higher than preset flow, has not been clarified to date. Methods: The relationship between actual blood-removal and recircula...

introduction: decayed teeth are one of the diseases of civilization. intraoral factors which interact with the others such as heredity, cultural and social factors are involved in the initiation of the disease. among social factors, health care is particularly important. the aim of the present study was to evaluate dmft, dmft and gingivitis in the first-year students of elementary, guidance and...

background: catheter ablation is widely used for treatment of atrial fibrillation. the use of fluoroscopic and non-fluoroscopic mapping systems in catheter ablation is common. this study conducted to investigate the safety and effectiveness of navx non-fluoroscopic mapping system.   methods : in this study, the appropriate electronic databases including cochrane library and ovid medline searche...

Distinguishing Sequences (DSs) are used in many Finite State Machine (FSM) based test techniques. Although Partially Specified FSMs (PSFSMs) generalise FSMs, the computational complexity of constructing Adaptive and Preset DSs (ADSs/PDSs) for PSFSMs has not been addressed. This paper shows that it is possible to check the existence of an ADS in polynomial time but the corresponding problem for ...

1. Optical Frequency Standard Joint Services Electronics Program (Contract DAAB07-74-C-0630) David E. Pritchard We are trying to develop a simple and economical "frequency meter" to be used with a tunable laser to preset the laser frequency, measure the laser frequency, or provide frequency marker pulses when the laser frequency is swept. A prototype system capable of 50 MHz accuracy is nearing...

Radiotherapy is an integral component of management of high-grade soft tissue sarcomas. Interstitial brachytherapy is used to deliver a boost or radical dose with several advantages over external beam radiotherapy. There has always been a concern to use brachytherapy with flap reconstruction of skin defects after wide excision. We preset our initial experience with interstitial brachytherapy in...
