04. The incidence of failure following single-visit endodontic therapy
Richard B.Pekruhn. J Endod 12:68-72. 1986
Introduction
- Single-visit 근관 치료와 multiple-visit 근관 치료사이의 실패율 유의차 없음
- Single-visit 근관 치료는 다음 세 가지로 분류
① 초기접근, 근관 형성, 근관충전이 single-visit 근관 치료로 완료
② 통증

갑상선은 사람 몸에서 호르몬을 분비하는 내분비 기관 중 가장 크며 갑상선 호르몬을 만들어 몸의 기능을 적절하게 유지하는 일을 하는 중요한 기관이다. 여자에서 더욱 무거우며 생리나 임신 시에 더 커진다. 갑상선은 갑상 연골과 윤상 연골에 붙어 있는 나비모양의 갑상선 호르

In catalyst, oxygen produced from H202
With sodium hydroxide, luminol Dianion is formed
The oxygen reacts with luminol dianion
This product is very unstable, so decomposes to 5-aminophathalic acid
As the exited state, 5-aminophathalic acid relaxes to ground state
Excess energy is emitted as blue light
Alkaline luminol, H2O2 solution is used on detecting NO2
The presence o
In synthetic luminol process we need luminol’s precursor. That is
5- nitrophthalhydrazide. It is synthesized by the reaction of 3-nitrophthalic acid
with hydrazine. This process is condensation reaction. First, hydrazine(N2H4) is
heated with the 3-nitrophthalic acid. This reaction is most conveniently carried
out in the high-boiling solvent triethylene glycol. To boil off excess water, t

Criminalists mix the luminol (C8H7O3N3) powder with a liquid containing hydrogen peroxide
(H2O2), a hydroxide (OH-) and other chemicals, and pour the liquid into a spray bottle. The
hydrogen peroxide and the luminol are actually the principal players in the chemical reaction,
but in order to produce a strong glow, they need a catalys

Airport management, in common with others involved in the operation of elements of the civil air transportation system, are required to take measures that will provide a high level of protection of buildings and equipment (including aircraft), in addition to ensuring the safety and personal security of passengers and staff using the system. This must be done in manner that disturbs the normal ope
