It is associated with obesity (except in children, who may have normal body weight) and patients are usually overweight women, who present with swollen discs, headaches and often visual obscurations
The NFPA 502 (2004) defines the smoke obscuration
levels that should be considered to maintain a tenable environment for periods of short duration.
measurements are made in the exhaust duct by a helium-neon laser with silicon photodiodes as main beam and reference detectors, and appropriate electronics to derive the extinction coefficient and set also provided in the exhaust duct for isokinetic sampling probes for determining concentrations of gaseous combustion products, typically the carbon oxides.
Increasing market interest in reducing smoke obscuration
and corrosivity are helping to create opportunities for phosphorus additives as alternatives or complements to standard halogenated compounds.
The smoke commander and team leader demonstrate the capabilities of obscuration
on the battlefield.
The failure to synchronize effective suppression and obscuration
with obstacle reduction and assault, for example, can lead to swift, overwhelming losses of friendly forces at the obstacle or within the enemy engagement area.
I wanted to make a documentary that outlined the actual science, without all of the political obscuration
Over time, these markings become obliterated due to weather fading, failing paint, and rubber obscuration
It seems this will go on like this unless Davutoy-lu raises an objection to this process of obscuration
eclipse The total or partial obscuration
of light from a celestial body as it passes through the shadow of another body.
However, sparse orbital photometric data of the companion did not allow constraining the degree of tidal distortion to date, although suggestions were made that there are signatures of a strong tidal effects, for example; a large orbital period derivative; the pulsar is eclipsed for a significant portion of its orbit (~15%) and there is significant flux variability in the radio data (2000 MHz) which may be contributed by obscuration
material from a mass-losing companion that could be a star nearly filling its Roche lobe.
MID) has developed and manufactures the FloShield(TM) laparoscopic vision system, the first device that prevents loss of vision during laparoscopic surgery due to obscuration
of the optics.
