This study was undertaken to find out the trend of blood group distribution (ABO and Rh) among the 1310 Nepalese attended in Tribhuvan University Teaching Hospital and Nepal Medical College Teaching Hospital Kathmandu. The frequency of distribution of A, B, AB and O was 28.5%, 27.3%, 8.7% and 35.5% respectively. Only 0.8% of them were found to be Rh (-) ve. In this population of study, O (+) ve...

Three questionnaires that measure parenting style, adolescent-family connectedness, and mental health were administered to 351 Egyptian adolescents. Results show that in rural communities the authoritarian style is more predominant in the parenting of male adolescents, while the authoritative style is more predominant in the parenting of female adolescents. In urban communities, on the other ha...

Abstract Aiming at the problem of wind noise generated by transmission lines under windy weather conditions, this paper selects three groups in Shandong Province, China. Through fixed-point measurement pressure conductor ground projection point side, phase sags as starting point, and outward extension 50 m endpoint, frequency spectrum curve characteristics line, predominant frequency, cut-off o...

The frequency-noise power spectral density of a room-temperature distributed-feedback quantum cascade laser emitting at λ = 4.36 μm has been measured. An intrinsic linewidth value of 260 Hz is retrieved, in reasonable agreement with theoretical calculations. A noise reduction of about a factor 200 in most of the frequency interval is also found, with respect to a cryogenic laser at the same wav...

Perceptual grouping of successive frequency components, namely, auditory streaming, is essential for auditory scene analysis. Prolonged listening to an unchanging triplet-tone sequence produces a series of illusory switches between a single coherent stream (S1) and two distinct streams (S2). The predominant percept depends on the frequency difference (Deltaf) between high and low tones. Here, w...

During the AC electrokinetic manipulation of particles in suspension on microelectrode structures, strong frequency-dependent fluid flow is observed. The fluid movement is predominant at frequencies below the reciprocal charge relaxation time, with a reproducible pattern occurring close to and across the electrode surface. This paper reports measurements of the fluid velocity as a function of f...
