Ion-selective electrodes (ISE) offer a practical approach for estimating ionic activities. Nonetheless, such devices are not selective, i.e., the ISE response can be affected by interfering ions other than the target one. With the aim of overcoming this problem, we propose a Bayesian nonlinear source separation method for processing the data acquired by an ISE array. The Bayesian framework perm...

CONTEXT Performance on the Osteopathic General Surgery In-Service Examination (ISE) has been shown to improve over time for osteopathic general surgery residents. The training level-specific concurrent validity of the ISE, however, has not been evaluated. OBJECTIVE To investigate whether residents' scores will improve as they move from level 1 through level 5 of the ISE. METHODS In this ret...

This paper explores how people from low-income, minority ethnic groups perceive and experience exclusion from informal science education (ISE) institutions, such as museums and science centers. Drawing on qualitative data from four focus groups, 32 interviews, four accompanied visits to ISE institutions, and field notes, this paper presents an analysis of exclusion from science learning opportu...

تحقیق حاضر به بررسی رابطه راهبردهای یادگیری زبان دوم و فراگیری زبان عربی پرداخته و نقش رشته تحصیلی و جنسیت را در کاربرد این راهبردها مشخص نموده است. به این منظور، نخست از حدود 900 نفر از دانشجویان کارشناسی (ورودی 84-82) رشته های فلسفه و زبان و ادبیات عربی دانشگاههای تهران، الزهرا علامه طباطبایی، شاهد و امام صادق، تعداد 285 نفر به طور تصادفی برای پاسخ دادن به پرسشنامه راهبردهای یادگیری زبان دوم ...

Real time prosody modification involves changing the prosody parameters such as pitch, duration and intensity of speech in real time without affecting the intelligibility and naturalness. In this paper prosody modification is performed using instants of significant excitation (ISE) of the vocal tract system during production of speech. In the conventional prosody modification system the ISE are...

A technique for the selective measurement of diffusive gradients in thin-films (DGT) for free Cu2+ ions was developed using a 0.030 M solution of polyvinyl alcohol (PVA) as the liquid binding phase with the liquid-type DGT devices (PVA DGT). The PVA DGT had a substantial binding capacity at pH 5.6 - 8.6 and concentrations of competitive Na+ up to 0.7 M. The measurements of PVA DGT and cupric io...
