In aircraft, galleys are used as a compartment where food can be prepared to be served to the onboard passengers. The Douglas Aircraft Company was the first aerospace company to include it in its aircraft DC-3 in 1921. In commercial aircraft, the galleys typically not only include food preparation and serving equipment but also contain jump seats (for flight attendants) and emergency equipment.

Advertisements include any paid form of non-personal presentation and promotion of ideas, goods or services by an identified sponsor. It is an effective tool used in business to differentiate goods and services in a meaningful way to connect the consumer with the brand. Increasing competition in the business world has made it mandatory for businesses to advertise. In addition, the advent of digital media has made advertising an affordable proposition for SMEs. Advertising and marketing on digital platforms reaches a larger audience and helps the SMEs to stay competitive in the market.

Vitamins are of two sorts — water soluble (A, D, E, and K) and fat soluble (vitamin B and vitamin C). Vitamin B can be of the following types B1 (thiamine), B2(riboflavin), B3 (niacin), B5 (pantothenic), B6, B12, B9, and B7. The chemical ingredients that constitute vitamins are called vitamers. Vitamins can contain multiple vitamers. For example, Vitamin A contains six vitamers — retinal, retinol, and four types of carotenoids. Human body does not produce vitamin by itself, so human beings depend on secondary sources such as food and supplements for vitamins. Vitamins help the body to fight against diseases. All the 13 vitamins are essential for the proper functioning of the human body and for good health. Vitamins perform many biochemical functions such as regulating metabolism, aiding cell and tissue growth, and assisting enzyme-substrate reactions inside the living body. A deficiency of vitamins results in different health disorders and supplementation is required to overcome them. Vitamin supplements are fortified with vitamers or vitamin ingredients sourced from various natural and synthetic sources.

The global PPE market is primarily driven by an increase in the demand from APAC, where international companies are initiating stringent safety programs in their countries of operation. Certain countries in this region, such as Japan, Australia, and New Zealand, have well-defined government regulations on worker safety, which contribute to market growth. The manufacturing and construction industry in APAC is outperforming the global manufacturing and construction industry and will drive the demand for PPE over the forecast period. Stringent government regulations on worker health and safety also play a key role in the growth of this market.

In the past century, fossil fuels were the chief source of energy worldwide. Among fossil fuels, crude oil has controlled almost all the aspects of the energy business. Crude oil is defined as a mixture of compounds composed primarily of carbon and hydrogen in varying proportions. It also has inorganic compounds such as nitrogen and sulfur and metals like vanadium and mercury. Crude oil is found in specific rock formations, called reservoirs, in the earth's crust. The depth at which petroleum reservoirs are found can vary from oil seeps that flow up to the surface to almost 15,000-meter underground. To reach these reservoirs of crude oil, the surface needs to be drilled until the pre-defined depth is reached.

A normal form of a capacitor is a one that preserves and discharges electrical energy without any loss of energy. A discrete capacitor, on the other hand, can have losses of electric current due to the nature of its capacitor components. Discrete capacitors can be made of different materials such as ceramic or plastic dielectric and also have different types of build-up depending on the applications. These capacitors have varied capacitance fluctuation due to a higher level of frequencies.

The term cyber deception was coined in 1989 by Gene Spafford. He sourced active defenses to identify attacks in the network, slow down attackers while they attempt to infuse virus attacks, learn their techniques, and feed them with fake data. In 1999, the Honeynet Project was launched, with innovation to the deception techniques and ways to understand and learn the behavior and competency of attackers. In 2003, honeypots such as honeyd were introduced that had basic network emulation tools, which waited for inbound network connections and provided limited service emulations. Over a period, the honeypots improved and providers designed honeypots to actively crawl and evaluate potential harmful links.

Carbon brakes were originally used in military aircraft applications due to their low weight and high energy absorption capability. These were made widely available for commercial and civil aircraft in 1980. Historically, the cost association of carbon brakes was much higher than the conventional steel brakes, and their use was restricted to only large long-haul commercial aircraft.

Anti-ship missiles are guided missile systems, which are designed to be deployed against combat ships and large naval boats. To counter these missiles, anti-ship missile defense systems come into play. They consist of the following types: Missile interceptors, Close-in weapon systems (CIWS), Decoy systems, Electronic warfare (EW) equipment, Anti-aircraft guns.

The light sensor market continually experiences changes with the introduction of different types of sensors, which offer different applications such as ambient light sensing, RGB color sensing, gesture recognition, and proximity detection. These sensors are mostly embedded in mobile devices, such as smartphones and tablets, to control the brightness of the screen and save battery by reducing power consumption. They are also being integrated into televisions, home automation devices, and intelligent lighting for both energy-saving and security purposes.
