Hereâs what you can expect: 1  First, a speculum is placed in the vagina, just like for a Pap. The cervix is cleaned off with a soap solution.Then a soft flexible tube, thinner than the inside of a pen, is passed into the uterus. 2  The speculum is removed and the ultrasound probe inserted.
You will likely have similar results. Closed cell polyurethane foam will only absorb water if the individual cells are damaged, which CAN happen over time, but the causes of wet foam in boats isn't all that clear. It is likely that freeze cycles will gradually cause foam deterioration.
Originally aired in 2003. The first foam sample, a ceramic based acoustical material, does not burn. It is a Class A material. The second sample, a polyurethane acoustical foam, will burn but eventually extinguish.It is a Class C material. The third foam, which is for use as bedding-not as an acoustical product, ignites immediately and flames continue to spread even after the fire source is removed.Bedding or packing foam is not intended for use on vertical surfaces such as walls, or on ceilings.riginally aired in 2003.
