Fabrication of suction-cup electrodes for electromyography.
Many kinds of surface electrodes are used today in EMG, the small silver and gold cup being the standard electrode in the United States. A suction-cup surface electrode is rarely used but several years of experience with many kinds of electrodes in our laboratory have led us to the conclusion that this electrode has many practical qualities. The suction-cup electrode has several advantages over...

قاعده مقتضی و مانع در متون فقهی کم و بیش مستند احکام قرار گرفته و مورد مناقشه فقهاء و اصولیین می باشد و مشهور معتقند مقتضی و مانع، قاعده نیست بلکه یکی از مسائل ذیل استصحاب است لذا نگارنده بر آن شد تا پیرامون این قاعده پژوهش جامعی انجام دهد. به عقیده ما مقتضی دارای حیثیت مستقلی است و هر گاه می گوییم مقتضی احراز شد یعنی با ماهیت مستقل خودش محرز گشته و قطعا اقتضاء خود را خواهد داشت مانند نکاح که ...

IN the past few years there has been increasing interest in the use of the pressure cup technique for the investigation of aqueous humour dynamics. Rosengren (1956) demonstrated a rise of intra-ocular pressure when a positive pressure was applied to the sclera overlying Schlemm's canal. He suggested that this rise of pressure was due to continued formation and accumulation of aqueous humour, th...
متن کاملQuantification of Valve Stiction
Oscillations in control loops lead to poor controller performance. Stiction in control valves is one of the major causes of such oscillations. Therefore, the correct diagnosis of stiction is important. There are several methods for detecting stiction, but quantification of stiction still remains a challenge. Two parameters are used to model the stiction phenomenon successfully, namely, deadband...
متن کاملSurgical and prosthetic management of suction cup induced palatal perforation: case report.
Construction of complete dentures with adequate retention is a complex procedure. Various techniques have been tried to improve the retention of dentures. Use of suction cup in maxillary denture is one of the techniques to improve retention. Suction cup provides retention and stability by inducing negative pressure on the mucosal surface. Palatal Suction cups which provide high retention are no...
