Dental surgery involves diagnosis, surgical intervention, and adjunctive treatment of oral diseases. This science is applied to restore functional as well as aesthetic aspects of the oral and maxillofacial region, or damage due to any injury or defect involving soft and hard tissues. It can be as small as a tooth extraction or as complex as dental implant.

Bungee jumping is an extreme adventure sport. In this, a jumper does a free fall from a fixed tall structure like a cliff, bridge, or crane, as well as from a stationary hot-air balloon or helicopter, with the help of a harness and a rubber cord (commonly known as a bungee cord) attached to the body. The jumper bounces back to some extent when the bungee cord rebounds its maximum stretch, and continues to fly up and down until all the kinetic energy is dissipated.

Packaging machinery is used in the manufacturing industry for providing assistance in the packaging of products before they are dispatched for storage and distribution network. Packaging machinery is used in the primary and secondary packaging of food, pharmaceuticals, beverages, and personal care products. Primary packaging is one of the most vital parts of the marketing mix as it has a strong impact on the consumer buying decision. Packaging machinery is widely used for filling, coding, labeling, and wrapping up of products for increasing the safety and traceability of the packaged product.

A battery is a device that stores electric charge. It consists of one or more electrolytic cells that supply electric power when connected externally to devices such as flashlights, smartphones, watches and clocks, electric cars, etc. A battery analyzer or a battery tester is a device to check the state of an electric battery. Basic battery analyzers include ammeters and voltmeters that measure the charge stored in the battery under test and its voltage output. Advanced battery analyzers are capable of determining the battery's condition by evaluating critical parameters such as its capacity for accumulating charge and any conditions affecting the performance.

The main purpose of ballast water management systems is to reduce the harmful effects of the introduction of invasive aquatic marine life from one sea area into another through the ballast water discharged from shipping vessels. The International Maritime Organization (IMO) adopted a convention for the control, management, and sedimentation of ballast water on February 2004. After these regulations come into effect on September 8, 2017, it will become mandatory for state authorities all across the globe to formulate and implement their own regulations for ballasting and deballasting operations in ships, which sail into different territorial waters.

An automotive steering system acts as a direct line of control and communication between the driver and the vehicle. Automotive steering systems have evolved from being rigid mechanisms to more technologically advanced, smooth, reliable, and easyto- use systems. Modern automotive steering systems are equipped with advanced safety systems and advanced driver assistance systems (ADASs), such as airbags (in steering wheels), and controls for anti-lock braking system (ABS), adaptive cruise control (ACC), and passenger airbag systems (PAS) to ensure safe and smooth driving and to provide improved directional stability and agility to the vehicle.

Power factor controllers are mainly used to control voltage fluctuations and maintain optimum power factor for eliminating interference during machine operations. Power factor controllers include both automatic and manual controllers. The applications of both these controllers are similar, the recognition mode being the exception. Automatic power factor controllers use an automatic capacitor recognition mode whereas manual power factor controllers must be adjusted manually in times of fluctuation or decrease in the power factor. Manual power factor controllers are suitable for testing relay outputs. However, the use of these controllers is limited as most of them are getting replaced by automatic power factor controllers. This is because automatic power factor controllers are easy to use and maintain compared with manual power factor controllers.

The use of 3D glasses has gained popularity over the years with the growth of the media and entertainment industries. In 1838, Sir Charles Wheatstone developed the first 3D viewing device called stereoscope by applying the principals of stereopsis. The stereoscope was a flat board fitted with mirrors and lenses and was enhanced by removing mirrors to make the view easier through lenses. This resulted in a device called lenticular scope, which was the first portable 3D viewing device.

Batteries provide power to devices such as smartphones, flashlights, watches and clocks, and electric cars. These batteries consist of an electrochemical cell with electrodes, which provide the necessary charge when connected to an external device. Alkaline batteries use an alkaline electrolyte of potassium hydroxide (KOH). It consists of a positive electrode made of manganese dioxide and a negative electrode made of zinc. When the battery is connected, electrons flow from the negative electrode to the circuit to power the external device connected to the battery. The flow of electrons forms an electric charge.

The fall protection market is witnessing growth in North America; Asia-Pacific (APAC); Europe, the Middle East, and Africa (EMEA); and the rest of the world (ROW). Fall protection equipment is used in various commercial and industrial sectors to protect employees working at a height from injuries and mishaps. The market is growing due to the increasing demand from end-users such as wind energy, which are growing globally, and the increased adoption of fall protection for recreational purposes. Safety harnesses find applications in various end-user industries such as construction, oil and gas, and manufacturing.
