4B/5B is a block encoding system that breaks up long strings of zeroes and ones but does not increase the frequency bandwidth by breaking them up in four-bit sequence. Table 1 shows each block of four bits replaced by a block of five bits. Due to this, there cannot be more than one leading zero and two trailing zeros. This means that the resulting bit stream has no more than three consecutive zeros (Figure 1). This bit stream is transmitted using non-return to zero inverted (NRZI) method and is used in 100BaseTX (Fast Ethernet) networks ...

Introduction

For more than 150 million years, dinosaurs roamed across the earth. However, most dinosaurs became extinct suddenly within a short time. The last of the dinosaurs are estimated to have died about 65 million years ago. The cause of their extinction continues to be a mystery, with a number of factors such as diseases, climate change, geologic events and changing plant communities being thought to have played a part in the demise of dinosaurs. Of late, theories of dinosaur extinction have been the subject of much controversy and debate. The explanation that seems to have the support of many scientists spells out that ...

I/We have been assigned one of the most expensive metals, Platinum. It has widely application in dental implants, automotive catalytic converters (Rao & Reddi, 2000), biomedical implants such as catheters, stents, cardiac implants (Cowley & Woodward, 2011), manufacturing of optical glass, manufacturing of fuel cells (McDonald & Hunt, 1982) and jewelry.

Platinum ore deposits

Platinum ore contains palladium, iridium, rhodium, osmium and ruthenium, along with platinum. Platinum ore forms a) Placer deposits: Placer deposits are formed by water-based erosion of sedimentary rocks containing the ore (Example. Ural-Alaskan type). b) Layered igneous lode deposits: Such deposits are emplaced on stable cratons. Examples: South Africa as the Bushveld Complex, ...
