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.
Options include: Local anesthesia. Your dentist or oral surgeon administers local anesthesia with one or more injections near the site of each extraction. Before you receive an injection, your dentist or surgeon will likely apply a substance to your gums to numb them. You're awake during the tooth extraction.
