[2:183] O you who believe, fasting is decreed for you, as it was decreed for those before you
you may attain salvation.

2:183-187. Like all duties in Submission, fasting was decreed through Abraham
(22:78). Prior to revelation of the Quran, sexual intercourse was prohibited throughout the fas
period. This rule is modified in 2:187 to allow intercourse during the nights of Ramadan.

[2:184] Specific days (are designated for fasting); if one is ill or traveling, an equal number of
days may be substituted. Those who can fast, but with great difficulty, may substitute feeding
poor person for each day of breaking the fast. If one volunteers (more righteous works), it is b
But fasting is the best for you, if you only knew.

[2:185] Ramadan is the month during which the Quran was revealed, providing guidance for t
people, clear teachings, and the statute book. Those of you who witness this month shall fast
therein. Those who are ill or traveling may substitute the same number of other days. GOD w
for you convenience, not hardship, that you may fulfill your obligations, and to glorify GOD for
guiding you, and to express your appreciation.

Palladium Barrier Leak detector ASME V

2008-08-31T13:08:00.001+07:00

Palladium Barrier Leak Detector — a leak detector using
hydrogen as the tracer gas and using the principle of
hydrogen diffusing through a hot palladium barrier into
an evacuated vacuum gage

Coercive Force ASME V

2008-08-30T04:09:00.001+07:00

Coercive Force — the magnetizing force at which the
magnetic flux density is equal to zero. The corresponding
field intensity value is indicative of the ease of difficulty
or demagnetization.

Ion Pump ASME V

2008-08-29T06:02:00.001+07:00

Ion Pump — an electrical device for pumping gas comprising
a means for ionizing the gas and a system of
electrodes at suitable potentials, and in some cases also
a magnetic field, which causes the ions formed to move
towards a surface on which they are absorbed or buried

Yoke ASME V

2008-08-28T14:59:00.001+07:00

Yoke — a magnet that induces a magnetic field in the
area of a part that lies between its poles. Yokes may be
permanent magnets or either alternating-current or directcurrent
electromagnets

Penetrant Comparator ASME V

2008-08-27T10:13:00.002+07:00

Penetrant Comparator — an intentionally flawed specimen
having separate but adjacent areas for the application
of different liquid penetrant materials so that a direct
comparison of their relative effectiveness can be obtained

Sensivity Value ASME V

2008-08-26T07:01:00.001+07:00

Sensitivity Value — the value determined by the smallest
standard discontinuity in any given sensitivity indicator
observable in the radiographic image. Values are defined
by identification of type of indicator, size of defect, and
the absorber thickness on which the discontinuity is
observed.
