A boat’s steering wheel is part of the helm that connects to a mechanical, electric, or hydraulic system to assist in turning the boat. Boats with outboard motors steer with a wheel which rotates the entire drive unit; inboards sometimes use a pod with an attached propeller; personal watercraft use jet drives with an impeller to force water into a nozzle that the operator can turn to the desired course. Some modern ships replace the wheel with a toggle that remotely controls an electric or hydraulic rudder drive, with an indicator that shows the rudder angle in real time to the helmsman.
This report studies the Magnetic Reed Switch market. Magnetic Reed Switch consists of a pair of ferromagnetic reeds, which overlap at their free ends (contact area) at a very small distance and are hermetically sealed in a glass tube. When in the presence of a magnetic field, the reeds become magnetized to opposite polarity, thus attracting each other and closing contact. Like many other great inventions, reed switches were born at Bell Laboratories, invented there in the mid-1930s by Walter B. Elwood. Today, reed switches are still in common uses.
This report studies the Locomotives market. Locomotive is a rail transport vehicle that provides the motive power for a train. Locomotives use electricity to drive forward motion despite some locomotive named 'diesel'. In diesel locomotive, a large diesel engine turns a shaft that drives a generator which makes electricity. This electrical energy powers large electric motors at the wheels called 'traction motors'.
Liquid Chromatography Detectors is a device used in liquid chromatography (LC) to detect components of the mixture being eluted off the chromatography column. A broad range of detectors is available to meet different sample requirements. Specific detectors respond to a particular compound only and the response is independent of mobile phase composition. On the other hand the response of bulk property detectors is dependent on collective changes in composition of sample and mobile phase.
Liposomes have been used to improve the therapeutic index of new or established drugs by modifying drug absorption, reducing metabolism, prolonging biological half-life or reducing toxicity. Drug distribution is then controlled primarily by properties of the carrier and no longer by physico-chemical characteristics of the drug substance only. 
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes. There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind (windmill) or water (watermill). Today they are usually powered by electricity.
