Reinsurance is a risk mitigation strategy adopted by insurance companies to spread their risk and make their business more profitable. Under this system, insurance companies reinsure their sum of insurance policies with reinsurance companies at a fraction of the premium. Sometimes reinsurance companies also sell such reinsurance to other reinsurance companies.

Central venous access devices are devices inserted into the central venous system to administer medication or fluids, draw blood, and measure central venous pressure. These devices are made up of a non-irritant material such as silicone so that they can be left in place for several weeks or months. Central venous access devices are recommended when there is difficultly to obtain peripheral venous access or in case of certain intravenous therapies such as chemotherapy, total parenteral nutrition, prolonged medication, repeated transfusions of blood or blood products, and frequent blood sampling. These devices are inserted either by surgeons or interventional radiologists with or without the use of general anesthesia. CVCs, PICCS, and implantable ports are the most common types of central venous access device. The catheter has one end positioned outside the body and the ports are surgically placed under the skin and require a special needle for access. Occlusions are a common complication associated with these devices, which can be thrombotic, mechanical, and precipitate occlusions.

ALS, often referred to as Lou Gehrig's disease, is a progressive neurodegenerative disease that affects neurons in the brain and spinal cord. In ALS, degeneration of the motor neurons leads to their death. As a result the brain loses its ability to initiate and control muscle movement. Patients in the later stages of the disease may turn out to be totally paralyzed. Muscle twitches, cramps, tight and stiff muscles, slurred and nasal speech, and difficulties in chewing or swallowing are some of the common symptoms observed in ALS patients.

Unconventional gas is a type of natural gas resource that is trapped in coal beds, shale blocks, and tight sands. These gas resources are different from conventional sources in terms of reservoirs, geographical areas, and accumulation of natural gas. For the extraction of unconventional gas, different techniques are applied depending on the field and type of gas extracted. One common method is hydraulic fracturing, where a hole is drilled into the rock and large amounts of water are injected at high pressure along with sand and other chemicals to create cracks in the rock. The cracks, when opened, will free the trapped gas, allowing it to flow to the wellhead. There are three types of unconventional gases: tight gas, shale gas, and CBM, as shown in the exhibit below.

An automotive turbocharger is a component that compresses air fed to a vehicle's engine. This helps the engine produce more power, offer improved fuel efficiency, and afford cleaner fuel combustion, thus improving overall performance. An automotive turbocharger mainly consists of three components: a turbine, a compressor, and center housing. Automotive turbochargers are further classified as standard, ball-bearing, twin-scroll, and variable-geometry/variable-nozzle turbochargers.

Three-dimensional flat panel TVs display images with depth perception. To achieve this, these devices employ various technologies such as stereoscopic display, multi-view display, and 2Dplus-depth. Special glasses are required to experience this depth perception technology. Other technologies such as an active shutter 3D system and a polarized 3D system or an autostereoscopic system (which facilitates 3D viewing without the need for glasses) are also used by the vendors. This technology is in great demand for gaming purposes, viewing 3D content, and television broadcast.
