The Quake AlarmTM is a small plastic device that is not much bigger than a thermostat that mounts onto a wall with adhesive velcro strips and it operates off a nine-volt battery. The internal components are made up of a patented reverse pendulum system that is sensitive to P waves that precedes an earthquake.
Swelling occurs whenever the organs, skin, or other parts of your body enlarge. It is typically the result of inflammation or a buildup of fluid. Swelling can occur internally (within the body) or it can affect your outer skin and muscles. A range of conditions can cause swelling. Insect bites, illnesses, or injuries often result in external swelling. Internal swelling is often a side effect of medication or the result of a serious injury.
Gum swelling results from excess fluid (edema) in the soft tissues of the gums and may be accompanied by redness, pain, sores, ulcers and bleeding. Poor oral hygiene, resulting in inflammation or infection, is the most common cause of swollen gums.
