Patient discussion about decay

Q. what would be the best way to protect my teeth from decaying?i fill pain always in my private parties,what prb whenever i take long with out sex,so i would like the advice from my fewwol

A. i fail to see the connection between teeth and groin pain...about the teeth. it's very very simple- get used to a healthy oral hygiene. brush your teeth in the right way twice a day for at least 6 minute. use floss. go to a dental hygienist, she'll guide you through it.

Q. Whether it`s possible for Bipolar disorder in children?

A. It is possible for children to suffer with bipolar disorder. It is a tricky diagnosis in children I would strongly suggest professional help when dealing with children with bipolar disorder.
I wouldnt trust the diagnosis of a GP, I would suggest getting a referal to a pediatric psychiatrist for a through evaluation and proper treatment

So far, in its seven-month-long run, the GERDA experiment - which consists of 78.5 pounds of germanium held in a vat of liquid argon - has failed to detect any signs of such decay. But, at the same time, it has placed a lower limit on how often such an event happens, and, more importantly, shown that the experiment is incredibly successful in eliminating background noise.
The National Child Dental Health Surveypublished in 2005, found 52 per cent of five-year-olds in Wales had suffered tooth decay, needing fillings or teeth removed.

Although sterilization is an excellent approach for eliminating decay fungi, questions have arisen concerning whether it is necessary for species with naturally durable heartwood, such as western red cedar.
[3] Nuttal [2] discusses the criteria for maximizing asymptotic decay and minimizing the sidelobe peaks, along with the tradeoff in achieving one characteristic at the expense of the other.
Neutral particles that have not yet been seen could be searched for, even if they are stable or have long enough lifetimes that they would have only a very small fraction of their decays inside the detection apparatus.
If the act of filling the trap produces radioactivity with a lifetime comparable to the neutron lifetime, and the decays are detected, a systematic uncertainty in the measured lifetime will result.
