A true geostationary orbit is almost never achieved. Geostationary means inclination = 0 and e =0. In most cases, you donât want this. Certainly not e = 0, though you do want e to be small, but still measurable/computable. The reason why is that if your eccentricity = 0, then your argument of perigee is undefined, which makes it hard to compute a Keplerian vector.
âNumbing Gelâ is the patient-friendly name for Topical Anaesthesia. If you are phobic about dental pain, about needles or about injection, you dentist can apply numbing gel to your gums before the injection. This helps to reduce the pain of the needle as it enters the tissue.
Numbing gel contains an anesthetic agent, most commonly benzocaine (usually at a concentration of 20%). A cotton swab or q-tip is used to apply a small amount of gel to the injection site. Yes it does, but thereâs a slight snag. It needs to be left on for about one minute, in order to be really effective.
