mobil-, mobi-

1. That which moves by means of mechanism and power within itself; especially, of a vehicle; self-propelling as distinguished from horse-drawn.
2. A self-moving vehicle; a motor vehicle.
3. A road vehicle, usually with four wheels and powered by an internal-combustion engine, designed to carry a small number of passengers.

1. A passenger vehicle that is powered exclusively by an electrochemical power source, or partially so powered; such as, a hybrid electric car.
2. An automobile powered by a motor supplied with electric current from a storage battery or other device; such as, a fuel cell.

Electric cars were popular between the late 1890's and 1910 and interest in them has revived with new methods of generating electrical power.

1. The average electron-drift velocity in a semiconductor divided by the externally applied electric field.
2. A drift mobility of electrons in a semiconductor which consists of the electron velocity divided by the applied electric field.

1. The tendency of cells or compounds in a solution to move in an electric field toward an positive or negative electrode.
2. A characteristic of living cells in suspension (a dispersion of fine solid or liquid particles in a fluid) and biological compounds (proteins) in a solution to travel in an electric field to the positive or negative electrode, because of the charge on these substances.

The property of a barrier material that facilitates or impedes the movement of electrostatic charges internally or on the surface.

A horse-drawn vehicle; such as, a wagon.

The use of a hippomobile or a horse-drawn vehicle.

1. Unusual flexibility of the joints or greater than the normal range of motion in a joint, allowing them to be bent or moved beyond their normal range of motion.

Hypermobility is often misused to describe extra movements as seen in a contortionist.

2. Increased range of the movement of joints, joint laxity, occurring normally in young children or as a result of disease; such as, Marfan's syndrome (disorder of connective tissue of musculoskeletal system or abnormal length of the limbs; especially the fingers and the toes) or Ehlers-Danlos syndrome (disorder of the connective tissue; such as, joints that bend too easily into extensions).
3. Excessive joint play (movement) which permits increased mobility.

The area where two bones meet is called a joint and all joints have a cavity containing a small amount of synovial fluid, which allows for movement.

The attached tendons, muscles, ligaments, and joint capsules hold the joints in their correct positions.

Looseness of these supporting structures allows a joint to have extra motion and often, even normal activities that put stress on loose joints will irritate them.

Hypermobility syndrome may include congenital hip dislocations; scoliosis (curvature of the spine); elbow, kneecap and/or shoulder dislocations; or frequent ankle or wrist sprains.

A chemical sensor that is highly selective due to a specific enzyme incorporated into its structure.

The ratio of the average drift velocity of an ion in a solution to the magnitude of the electric field causing the drift.
