We request to Chief Minister of Sindh Qaim Ali Shah to give Appointment for meeting enable us to clear our Point of view that, Indentors
should not be in regime of Service tax, as they are Exporter of services to their foreign Principals and in return they Get Commission in shape of precious Foreign Exchange for our country They Added
jp/), in which the indentor
was driven by a stepper motor and controlled by a computer [21-22].
Characteristic features of humanly processed seeds included ringcracks on the sides and ends of the seed where the indentor
met the seed, irregularly fractured edges of seeds where the force propagated through the seed, and other small fractures on the seed shell (Asmussen 2005; see also Beck 1989 and Beck et al.
Therefore, the study region affords an excellent opportunity to document processes of indentor
corner tectonics; specifically, the manner in which strike-slip displacements along the Dinaride margin are accommodated by oblique transpressional deformation and thrusting in NW Slovenia and adjacent areas of the Italian Friuli Alps.
In addition to an optical microscope, the system has an atomic force microscope (ATM) equipped with a specially designed probe to measure particle shapes, and a diamond compression indentor
whose tip is flattened using a focused ion beam (FIB) process to the extent that the tip is 1 micron in diameter, narrow enough to compress just a single particle at a time.
Vickers microhardness was measured using Matsuzawa microhardness tester using a diamond pyramid indentor
To test hardness, engineers use a machine that forces a shaped indentor
, often a diamond because of its hardness, into the surface of the test material.
All preset parameters can be set up in test files, and the complete range of test loads and indentor
sizes also can be added.
Most use some type of indentor
which is forced into the material under controlled load (attention is brought to the alternative discussed in the first part of this article where electrical conductivity can sometimes be used to provide a totally non-destructive measure of hardness).
A Vickers indentor
attached to a Leitz microhardness (MH) tester was used to perform microindentation measurements.
e Tecnica S/A, Sao Paulo, Brazil) with a Knoop indentor
and static load of 25 g and with 5 seconds of dwell time.
The microhardness of the condensate was measured on cross sections by the Vickers method using a Polyvar Met optical microscope with the constant load on the indentor
of 49 mN with the duration of 10 s.
For examination of surface relaxation kinetics, other coating samples with the same thickness were scratched using the "high-throughput" method in Hysitron Tribolndentor[R] with a Berkovich diamond indentor
of tip radius R < 100 nm.
1995; Allen 1997) is the use of pressure flaking (ie the use of an indentor
to remove flakes from an artefact) in their manufacture.
For example, in an early account of pressure flaking, Clement (1903:5) confused how the indentor
was held and used.
