Air ambulance services are advanced and sophisticated medical services extended through the use of use of air transportation, airplane, or helicopters. They are the most efficient mode of shifting critical patients to hospitals as they consume much less travel time. Air ambulances have onboard medical treatment facilities and trained medical crew to treat patients in an emergency until they reach the hospital. These services are effective in serving people in war-torn areas and those affected by natural disasters. They also assist in the event of an outbreak of epidemics.

Plastic styluses entered the market along with touch-based gadgets. However, these styluses lost traction in the market as these were prone to misplacement and loss on the part of the user. Styluses are again being introduced in the market with the launch of tablets. Though initially, many tablets were not designed for the use of styluses and were intended to be touched specifically by fingers alone. However, the advances in technology of tablets are increasing the scope of usage of styluses in tablets.

Biogas is produced through anaerobic digestion of organic matter in which bacteria degrade biological material in the absence of oxygen. It is a renewable fuel that contains a mixture of methane, hydrogen sulfide, and carbon dioxide. Biogas is mostly used in farms where the waste and residue are converted into sustainable green energy.

Plastic recycling decreases the quantity of wastes that are being dumped into landfills and aids in transforming the wastes into lower or same grade plastic materials. These products are used across different sectors. A large proportion of the plastic that is procured for recycling is not suitable for recycling as most plastics used are semi-porous and absorb molecules of the stored material. The removal of these residues is tedious and additional treatments for the same can potentially alter the properties of the recycled plastics. Most recycled plastics are used to make lower grade products. These are hydrolyzed to a monomeric form and then purified and re-polymerized into food grade plastic.

Atrial fibrillation (AF), a type of heart arrhythmia, is a heart condition wherein the heartbeat too fast, too slow, or irregular. According to a study in 2013, about 33.5 million people had arrhythmia worldwide. As per the estimation by Centers for Disease Control and Prevention (CDC), in 2015, about 2.7-6.1 million people had AF in the US. This condition is mostly seen among the older population (aged 60 and above). It occurs because of the malfunctioning in the electrical system of the heart, which leads to sudden cardiac arrest or heart failure.

AHTS vessel is a ship built to handle anchors for oil rigs, tow them to location, and anchor them up, and it also serves as an emergency response and rescue vessel. The AHTS vessels are explicitly designed for anchor handling operations. Moreover, AHTS vessels are used to transport supplies to offshore drilling rigs and also provide towing assistance during deep-water anchor handling and tanker loading. AHTS vessels are generally created to meet the critical conditions of the North Sea (a section of the Atlantic Ocean coasting European countries such as Great Britain, Germany, the Netherlands, and France), and can undertake supply duties there between land bases and drilling sites.

Aluminum is a preferred material in the automotive industry because of its strength, safety, and durability. Use of aluminum in passenger and commercial vehicles allows boosting of fuel economy and reducing vehicular emissions. The global automotive industry is driven by improvements in macroeconomic conditions and demands from the developing market. Automotive manufacturers have been using steel products for engine parts and auto sheets, which are now being replaced with aluminum.

Headlights in vehicles have evolved technologically since their introduction in the 1880s, from incandescent to the latest OLED and laser lighting technologies. Automotive lighting, including xenon lighting and signaling devices, includes the lights located on the front, sides, and rear of a vehicle. The primary uses of xenon lighting are to ensure visibility for the driver, improve vehicle conspicuity, and indicate the position and presence of other vehicles.

The global construction market will grow at a rate of 3.9%, which is faster than the global GDP growth rate of 3.1%. One of the major reasons for this growth is the rapid rise in urbanization and industrialization in Asian economies, which drives the demand for construction. Additionally, the US economy has recovered from past economic recessions, and the GDP is projected to grow at a rate of 2.2% in 2016. This will boost the growth of industries, including the construction market.
