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.
If you have very sensitive gums, try wearing the teeth whitening strips every other day. Also make sure you donât brush your teeth too hard before putting on the strips. Even if you donât have sensitive gums, the peroxide on the strips may irritate them. During the time I use the strips, I donât use my Sonicare electric toothbrush. I just use a regular toothbrush because itâs gentler on my gums.
