This debris can accumulate due to ice flow toward the surface in the ablation zone, melting of surface ice or from debris that falls onto the glacier from valley sidewalls.

It suggests that during a woman's menstrual flow, some of the endometrial debris exits the uterus through the fallopian tubes and attaches itself to the peritoneal surface ( the lining of the abdominal cavity ) where it can proceed to invade the tissue as endometriosis.

While most women may have some retrograde menstrual flow, typically their immune system is able to clear the debris and prevent implantation and growth of cells from this occurrence.

They are formed by either submarine debris flows, avalanches, mud flow or mass flow in an aqueous medium.

The Bar Harbor Formation, which is made up predominantly of sands and silts, and Cranberry Island Formation, made up from volcanic ash and magmatic debris, occurred under similar circumstances in the Silurian and Devonian periods, and were deposited on top of the Ellsworth Schist.

This was originally used in the Roman empire in the first centuries AD and BC, and expanded throughout the empire wherever alluvial deposits occurred The Romans used ground sluicing to remove overburden and the gold-bearing debris in Las Médulas of Spain, and Dolaucothi in Britain.

Another failure, this time complete, occurred on January 17, 1997, when a Delta II 7925 carrying the first GPS Block IIR satellite, GPS IIR-1, exploded only 13 seconds after liftoff, raining flaming debris all over Launch Complex 17 at Cape Canaveral Air Force Station.

If such an impact occurred, much of the resulting debris might still be orbiting the Sun in the vulcanoid zone.

Wilson concluded, " We can make one statement of fact: the fireball sightings — green or otherwise — occurred in areas that received radioactive debris from Operation Buster.

During the night of April 18, a series of large, explosive bursts occurred that may have followed collapse of parts of the cone into the vents and subsequent explosive clearing of the debris.

Although the base surge typically contains only about 10 % of the total bomb debris in a subsurface burst, it can create larger radiation doses than fallout near the detonation, because it arrives sooner than fallout, before much radioactive decay has occurred.

Many of these fatalities occurred as people ran out of buildings and were hit by falling debris.

This work will cover the most serious one-fourth of all land needing such treatment, and will consist of burning 250,000 acres of highly hazardous debris concentration, felling snags on 350,000 acres of high lightning-occurrence areas, prescribed burning on 3.5 million acres, removing roadside fuel on 39,000 acres, and clearing and maintaining 11,000 miles of firebreaks.

If your pool is located on or near sloping ground, it may have natural drainage which is certainly more desirable than to be faced with the annual expense and labor of first pumping out the water and then scooping out all the debris.

They are harder to clean ( due to the limited movement of the keys and their multiple attachment points ) but also less likely to get debris in them as the gaps between the keys are often less ( as there is no need for extra room to allow for the ' wiggle ' in the key as you would find on a membrane keyboard ).
