A supersonic business jet (SBJ) is a small business private carrier, which can accommodate 10 to 12 passengers and can fly at a speed of more than Mach 1. It efficiently reduces the travel time to half, as compared to other conventional business aircraft. Currently, aviation experts such as Airbus, Lockheed Martin, Aerion, HyperMach, and Gulfstream Aerospace develop supersonic business aircraft.

Niobium is a refractory metal that is valued for its unique chemical properties, including extraordinary resistance to heat and wear and inertness. It has a high melting point of 4,474.4°F and a boiling point of 8,900.6°F. It is used as an alloying element in steel production in the form of ferroniobium (Fe-Nb). Niobium was first identified in 1801 and initially called columbium as it had been found in the US. After the discovery of tantalum in 1802, it was believed that these two metals were identical. However, Heinrich Rose concluded in 1844 that tantalum and niobium were different metals. He renamed niobium after Niobe, the daughter of Tantalus in Greek mythology. The name reflects the fact that these elements are often found together in nature and have strong geological and chemical similarities.

Holter monitors are small, portable, and battery-powered devices that help monitor and measure the electrical activity of a person's heart continuously for 1-2 days. Physicians use these devices for monitoring ambulatory patients who are susceptible to latent lifethreatening cardiac abnormalities. These devices also help in follow-up treatment for heart attack, measuring heart rate variability, identifying silent ischemia/ST segment analysis, identifying people at risk of sudden death, and detecting implantable pacemaker malfunctions.

A foundation cream is an integral part of any makeup regimen. The increase in the awareness of makeup and its role in enhancing outward appearance has positioned it as a daily necessity. Cosmetic products have become a necessity as a tool to raise self-esteem and gain social acceptance. Although the concept of beauty differs from society to society, the increasing influence of social, print, and digital media has created an objective sense of beauty.

Cardiology electrodes, composed of metal, lead, plastic, or cloth and electrode conducting gel, help convert ionic energy to electric current in the body and amplify the electric current for the diagnosis and treatment of diseases. These electrodes also help record the heart's electrical activity by placing them on the skin of the upper torso during ECG. This procedure helps diagnose cardiovascular diseases such as pulmonary embolism, cardiac murmurs, myocardial infarction, and cardiac dysrhythmias.

The global allergy immunotherapies market is expected to grow at a CAGR of 7.3% during the period 2015-2020. In 2015, Europe dominated the market, with Germany and France being the major contributors; a trend that is expected to continue during the forecast period. The market in Europe is characterized by approximately 1.3 million individuals eligible for allergy immunotherapy (AIT). Growth across Europe is attributable to the presence of approved SCIT products, such as Grazax. As a result, the SCIT/SLIT drop in the region accounted for 92% of the market share while SLITT accounted for only 8% in 2015. Further, the recent approval of Acarizax in 11 European countries, such as Germany, Italy, France, the UK, and Spain, will likely drive the market. Europe was followed by North America and ROW in terms of market share.

Precision air conditioners are reliable systems, which are capable of operating continuously while offering precise control over temperature and humidity of the data center environment. These units are specifically designed to cool the IT equipment in data centers. Precision air conditioners comprise of an indoor and outdoor unit. They are used to supply cold air through the cold air inlet of data center racks and exhaust hot air from the air outlet. The hot air is treated to optimal temperature and humidity and then supplied as cold air.

E-nose is a complicated term and it has a number of definitions. According to us, it is the purpose of the device that defines an e-nose and not a particular application area or an end-user segment. Therefore, we consider e-noses as devices that can be used to detect odor irrespective of what the device is called (gas chromatography, mass spectrometer, or ion-mobility spectrometer). An e-nose consists of three primary components: a sample delivery system, a detection system, and an analyzing system.

IoT is a web of physical devices connected to the Internet, enabled by sensors and software to collect and transmit data. Using IoT users can collect massive amount of data and convert into meaningful information by with the help of advance analytics techniques. The concept of IoT has evolved with the introduction of automated machines, such as automated teller machines (ATMs) and advanced interaction technologies like machine-to-machine (M2M) and human-to-machine (H2M). All these allow the users to establish seamless communications.
