Most ova probably survive about six to twelve hours after ovulation. However, for the purposes of contraception, you must count on a 24-hour survival period, plus an additional 24 hours in case there is a multiple ovulation.

Sperm in the cervical mucus of a woman's vagina can survive for up to six days - possibly seven. Without the cervical mucus to both nourish and protect the sperm, the sperm will die within one-half to four hours. Anyone who has touched semen should wash and dry - or at least wipe off - before touching the vulva or vagina.

The HIV virus is very fragile outside the body, but it can live from several minutes to several hours on the surface of objects in the environment, depending on the situation and environmental factors. The potency of the virus outside the body diminishes over time, but the virus must get directly into the bloodstream to infect anyone. Most household cleaners such as soap, bleach or peroxide will kill it. When cleaning any blood spills, use universal precautions.

Head lice die from lack of food or moisture in about two days if dislodged from a head. They may not live this long if it is very cold or they had not fed before being dislodged. Being dislodged means almost certain death for a head louse so they will avoid this if at all possible. They don't wander on to furniture or clothes very often as this would result in the death of the louse in most cases.

The survival of TASO clients varies greatly depending on the individuals and other factors. Currently TASO has some clients who were registered as early as 1988 but are still doing very well.

In general, enveloped viruses such as coronaviruses do not last a long time in the environment. In earlier studies, a different coronavirus was shown to survive for up to 3 hours on surfaces. At this time, it is uncertain how long the newly discovered coronavirus associated with SARS can survive in the environment. In one preliminary study, researchers in Hong Kong found that both dried and liquid samples of the new coronavirus survived as long as 24 hours in the environment.

Recent studies have shown that HCV can survive outside the body and still transmit infection for 16 hours, but not longer than 4 days.

After experiencing SCA, a victim’s chance of survival without an AED shock decreases by 7 to 10 percent with each passing minute. – American Heart Association

The smallpox virus is fragile. In laboratory experiments, 90% of aerosolized smallpox virus dies within 24 hours; in the presence of ultraviolet (UV) light, this percentage would be even greater. If an aerosol release of smallpox occurs, 90% of virus matter will be inactivated or dissipated in about 24 hours. (added Nov 13, 2002)

Your planet is a member of an enormous cosmos; you belong to a well-nigh infinite family of worlds, but your sphere is just as precisely administered and just as lovingly fostered as if it were the only inhabited world in all existence. The evolution of a human race, once initiated on a world of space, must proceed quite independently of the physical survival of that planet..

The egg retrieval requires approximately 15 to 30 minutes and patients are monitored for one to two hours afterwards.

Each program will vary in length; it depends on the clinic where the procedure will be done. Generally it takes 3 to 4 months.

The device is implanted permanently. The clinical trials require measurements of quality of life and heart size/function before the implant and at 6 months following implantation. Comparing the results from pre-operatively and at 6 months allows "long-term" assessment of the C-Pulse in regard of testing the device safety and performance. Patients' well-being will continue to be monitored following the end of the clinical trial assessment.

Preliminary studies in some research laboratories suggest that the virus may survive in the environment for several days. The length of time that the virus survives likely depends on a number of factors. These factors could include the type of material or body fluid containing the virus and various environmental conditions such as temperature or humidity.

Who is a carrier of hepatitis B virus? Sometimes, people who are infected with HBV never recover fully from the infection; they carry the virus and can infect others for the rest of their lives. In the United States, about one million people carry HBV.

In the UK, life expectancy for children has improved and subsequently increased with the development of combination therapy. Today for example, adolescents who acquired HIV at birth have now reached their 20th birthday. Therefore, as treatment and research advances there is hope for a much improved quality of life. There is a small core of children who are "long-term non-progressors" aged between 12-16 who have yet to start on any HIV therapy.

It has come to our attention that a large number of visitors to our site are coming here seeking additional information on the survivability of ants underwater. Please note that we are not ant experts; this entry was put here mainly as a joke. All of our knowledge of ants has come from the old Maxis game SimAnt. If you are seriously seeking information on ants, we advise that you look at the Wikipedia entry for ants.

Lobsters have special gills that allow them to survive out of water. If they are kept cool and damp, lobsters could probably survive out of water up to a week - but we wouldn't recommend eating them!

We are only human and need feeding and watering occasionally. We do request that you make arrangements with your venue to provide us with drinks and a meal during our stay with you.

All the facts regarding DXSynergy point to a long-term road map for GDT Inc. As it currently stands, there are far too many who think DXSynergy is going no where and are quite frankly, scared. As a result, the funds they InXchanged just a few short months ago are now exiting DXSynergy in a panic. I am convinced of the long-term profitability that has been underway for the past six years.

Their resistance to fasting is very big. The fifth stage nymph (previous to the adult stage) survives 6 months without food

I have personally killed released and/or escaped banded birds two years after their freedom. However, habitat, predators, available feed and the availability of water all figure into the equation.

The alphabet is remarkably easy to memorize, taking most people about 2 hours just for the letters alone. (Contrast this to weeks or months to learn how to type on a typewriter; also 2 hours is roughly the same time it takes to learn Graffiti for the PalmPilot.

Yes, we do have a Donor Egg Program. The waiting time for a Donor can fluctuate but we do screen potential Donors throughout the year and maintain our records for prospective recipients.

From the time when they initially pierce the egg, it usually takes between 8-24 hours. The first small fracture is to permit air breathing to begin - prior to this time the embryos oxygen demand has been met via permeation through the egg shell. This first small hole is gradually enlarged over the next few hours. The hatchling may then sit in the egg for quite some time whilst its egg sac is absorbed.

It's hard to say exactly because it depends on the design. A simple egg usually takes about a half hour to an hour. The more intricate patterns can take anywhere from two to eight hours.

About 30 hours, but it varies with the species. Cracks will appear a couple hours before the egg hatches.

Most breeders incubate for 48 to 56 days. Since the eggs are dark green in color, they cannot be candled. Instead, breeders tap the egg and watch for movement or use a night scope and a heavy-duty MagLight.

At the present, there is no method of growing the cloned egg into a fetus. It must be transplanted into a uterus for further development.
