This study examined the attitude of teachers towards the use of self-made video compact disc and its effect on JS II students’ academic performance in social studies in Calabar Municipality. Teachers’ Utilization of Video Compact Disc Questionnaire (TUVCDQ) and Social Studies Performance Test (SSPT) were administered to 12 teachers and 600 JSS II students respectively from 12 schools purposivel...

In this paper we have investigated compact printed semicircular disc monopole antenna, which is basically printed microstrip antenna with etched ground plane for UWB applications. In particular we have simulated very compact semicircular disc monopole antennas for UWB communication. Simple rectangular microstrip line is used for feeding the printed monopole antenna and its frequency bandwidth u...

Two protocols developed for the Tonal and Speech Materials for Auditory Perceptual Assessment audio compact disc are low- and high-pass filtered versions of the Northwestern University Auditory Test No. 6 (female speaker). Two experiments were performed on subjects with normal hearing to determine the needed filter characteristics of the words. In Experiment I, word-recognition performance was ...

The so-called “stationary” Hα line of SS433 is shown to consist of three components. A broad component is identified as emitted in that wind from the accretion disc which grows in speed with elevation above the plane of the disc. There are two narrow components, one permanently redshifted and the other permanently to the blue. These are remarkably steady in wavelength and must be emitted from a...

In many situations, it is necessary to transmit data from one place to an other. A classical example is the transmission of data via satellites. Also playing music on a compact disc is an example of data transmission; the music stored in a binary form on the compact disc is transmitted via a laser beam to the compact disc player and reconverted into music. During the transmission of data, it is...

ISI@ is introducing a new version of the Science Citation hdex~ (MW ) on compact disc read-onlymemory (CD-ROM), A unique feature of the SCf Compact Disc Edition is its “related records” function. This feature, created by “bibliographic coupling, ” allows the user to examine relationships between papers based on the cited references that they share. The SC1 CD Eiiirion brings a creative, intuiti...

Compact disc versions of the frequency (pitch) and duration pattern tests are reported. Results are similar to previous reports on these tests using taped materials. Mean performance of normal-hearing young adults for both pattern perception tests was approximately 90 percent. There was no effect of the two presentation levels used in this study. The compact disc version of these tests provides...
