Maintenance, repair, and operations (MRO) refers to the processes, activities, and materials necessary to maintain and support the operational standards of facilities and equipment within an organization.

Lung cancer is a malignant tumor that is caused by the abnormal or uncontrolled growth of cells in the lung tissues. It is the second-most common type of cancer globally and is the most common cause of cancer￾related deaths in the world. It is of two types, namely, non-small-cell lung cancer (NSCLC) and small-cell lung cancer (SCLC).

Loyalty management can loosely be defined as the strategy, tools, and tactics of how the employer or organization acquires, engages, and retains customers, which helps the brand target the correct target market and then gives benefits, experiences, and rewards that drive ahead the long-term engagement.

Lithium-ion battery recycling is a process that aims at diminishing the number of lithium-ion batteries being disposed of as solid waste. Lithium-ion batteries consist of several heavy metals and toxic chemicals. Therefore, disposing of them as regular trash has raised concerns about water pollution and soil contamination. Recycling spent lithium-ion batteries will aid in resolving new challenges arising from the clean energy transition and avert concerns brought on by improper battery disposal.

Location-based service (LBS) i s provided via location-enabled mobile devices. This software application uses real-time data to track the geographical location of the mobile user via geographic information system technology as well as the Internet.

Lithium-ion batteries are rechargeable batteries in which carbon serves as an anode and lithium-ion acts as a cathode. The advantage of using these batteries is that they increase thermal stability, have higher current density, and have a longer shelf life than other battery technologies available in the market. Lithium-ion batteries are used in high-power applications such as HEVs, EVs, and consumer electronics devices. One of the key reasons for this significant growth is the increased adoption of EVs and HEVs worldwide.

Lithium carbonate is a lithium salt of carbonate consisting of lithium, carbon, and oxygen elements. Lithium carbonate is a white, crystalline powder that is commonly used in industrial applications, with its primary significance in the field of energy storage, particularly in the production of lithium-ion batteries.

An object that orbits the planet at a lower altitude than geosynchronous satellite is known as a low Earth orbit (LEO) satellite. These objects are typically pieces of electrical equipment. Between 2,000 and 200 kilometers above the surface of the planet, LEO satellite orbit. LEO satellite is frequently used for imaging, spying, military reconnaissance, and other types of communications. Compared with a satellite at a higher altitude, LEO satellite has a much smaller communication field with the ground. They rotate around the planet more quickly as well.

Linear actuators are used to convert energy (power from air, electricity, or liquid) into linear motion. These actuators convert rotary motion into linear motion by means of a linear motor, a belt, or a screw drive. The linear actuators that convert energy from air into linear motion are called pneumatic linear actuators; the linear actuators that convert energy from the fluid into linear motion are called hydraulic linear actuators, and the linear actuators that convert energy from electricity to linear motion are referred to as electric linear actuators.

A leisure boat is typically used for entertainment and tourism. It can be powered by a motor or non-motorized and includes various types, such as sailboats, cabin cruisers, towboats, jet boats, watercraft, and runabouts, among others. These boats are popularly purchased and used for activities such as sailing, boating, fishing, or campaigning. Due to the ability to maintain social distance while enjoying oneself, boating has become a favored leisure activity in many regions and countries, leading to a surge in boat purchases.
