Test results with several grades of polypropylene, processed at various operating conditions, show that the geometric parameter is an intrinsic characteristic of the mixer/rotor combination, independent of material and processing conditions.
It was determined experimentally that the grade of the processed polymer composite material has the largest influence upon holes shrinkage.
EMR signals were clearly generated in different metamorphic grades of the coal-heating process.
In this paper, the time-varying characteristics of EMR during 3 metamorphic grades of the coal-heating process were studied.
As improvements in mining technology allowed lower grades of ore to be processed, and new heavy equipment allowed greater amounts of rock to be moved, mining in Death Valley changed.
The United States would be the most likely beneficiary of a new Mexican oil boom since its fields are close to Gulf of Mexico refineries, which are already designed to process various grades of Mexican crude.
The number of students exploiting new rules allowing them to change their choice of universities or courses if they receive combined A-level grades of ABB and above – a process known as "adjustment" – has more than doubled compared with 2012, although the overall number remains small.
However, for certain grades of steel, the hot charging process may affect the steel surface quality.
In order to satisfy the requirements of productivity and quality, in recent years, LASER welding processes of certain grades of steels mainly thin sheets assemblies or tailored welded blanks (TWBs) have given many successful advantages in manufacturing engineering.
The QSL, or Queneau-Schuhmann-Lurgi, process treats all grades of lead concentrates, including chemically complex secondary minerals, in a refractory-lined reactor into which oxygen and natural gas are blown through tuyeres at the bottom.
