Reliability Issues – Centrifugal Slurry Pumps Introduction Pumps were probably the first machine ever developed‚ and are now the second most common machine in use around the world‚ out-numbered only by the electric motor. The very earliest type of pump is now known as a water wheel‚ Persian wheel or “noria”‚ consisting of a wheel of buckets that rotates to pick up water from a stream and dump it into a trough. Another early pump was the “Archimedean screw”‚ similar to the modern screw conveyor

1. Nordson do Brasil: Challenges in an Emerging Market Gregory Merk‚ General Manager-Latin America South (LAS) and the head of Nordson do Brasil‚ a wholly owned subsidiary of Nordson (Nasdaq: NDSN)‚ was deep in thought in his Tambore office in Sao Paulo. He was thinking about his plan of action for his first 2002 quarterly meeting at Westlake‚ Ohio‚ worldwide headquarters (HQ) of Nordson. This was to be a crucial meeting‚ more than a mere update – HQ wanted to be apprised of the problems and issues

ABSTRACT For many years‚ the use of natural polymers for the fabrication of packaging materials has been an interesting alternative to replace non-biodegradable polymers which are normal components of these materials. The core problem of these starch based plastics is their hydrophilic character and the fact that they tend to become brittle with ageing. Unmodified starch is too much hydrophilic to be used as food packaging material. Chemical modification must be carried out in order to make them
