In this paper, we describe the design and implementation of a prototype software video production switcher, vps, that improves the quality of the content of MBone broadcasts. vps is modeled after the broadcast television in-dustry's studio production switcher. It provides special eeects processing to incorporate audience discussions, add titles and other information, and integrate stored videos...

To provide public service broadcasting on digital satellite, digital terrestrial and digital cable the BBC has been working in partnership with other UK broadcasters to develop widescreen digital television services ready for launch on DSAT and DTT in 1998 and subsequently on DCABLE. As the BBC is both a National and a regional broadcaster, the complexity and economics of distributing new servi...

There is no evidence that natural radiation (cosmic radiation or from natural radioiosotopes) increases the risk for thyroid diseases. Moreover, while it has been proven that exposure to external medical radiation or to external and internal radiation by atomic bomb explosions leads to an increased risk for thyroid cancer, the medical use of radioiodine, namely diagnostic and therapeutic applic...

As the nation's industrial complex grows, one of its attendant evils—environmental pollution—grows apace. Perhaps no segment of this complex grows more rapidly at present than the atomic energy industry. Responsible officials are gradually becoming aware of the potential for pollution of this new giant. The problem is complicated by security requirements and by virtue of the inability to sense ...

Radiation is considered one of the possible causes cancer disease with natural background sources including cosmic, terrestrial and internal radiation. A number cases have been reported in Kargi their not properly documented. The present work characterized radioactivity soil water, to find out radiation KARGI-KENYA by studying magnetic intensities, anomalous zones depth delineating subsurface s...

In this work, we systematically study the two-proton($2p$) radioactivity half-lives using two-potential approach while nuclear potential is obtained by Skyrme-Hartree-Fock with Skyrme effective interaction of {SLy8}. For true $2p$ radioactivity($Q_{2p}$ $>$ 0 and $Q_p$ $< $0, where $Q_{2p}$ are released energy one-proton two-proton radioactivity), standard deviation between experimental our the...

Plants of Hashilan, a 260 ha freshwater wetland, located at 35 km northwest of Kermanshah, the provincial capital of Kermanshah Province, western Iran, were studied. Altogether, 116 species of plants (77 terrestrial and 39 aquatic) representing 96 genera and 42 families were identified. Asteraceae with 11 genera and 13 species, Poaceae 9 genera and 10 species, and Cyperaceae with 6 genera and 9...
