Steel casting is a manufacturing process used to create steel components by pouring molten steel into a mold to solidify into a desired shape. This process is a type of metal casting, where the material is melted to a liquid form and then poured into a mold to produce objects of various sizes and complexities. The steel casting process can be broken down into several phases, including mold preparation, melting and pouring the steel, cooling and solidifying the metal, and post-processing. Steel casting allows the production of intricate and complex shapes that would be difficult or impossible to achieve with other manufacturing methods. The molds used in steel casting are typically made of sand, metal, or ceramics, depending on the process and the intended application of the casting

Stearic acid (C17H35CO2H) is a waxy solid saturated fatty acid, which contains 18-carbon chains. It naturally occurs in coconut oil, palm kernel oil, certain animal fats, and the milk of several mammals. It is commercially available in a mixture of either palmitic acid or a small quantity of oleic acid and is used in manufacturing detergents and cosmetics such as shampoos, shaving products, and soaps. The esters of stearic acid with glycol distearate and ethylene glycol create a pearly and soft effect in shampoos, soaps, detergents, and cosmetics products. In addition, stearic acid is also used in niche applications such as fireworks, metal processing and polishing, candles, and lead-acid batteries. Cleansers are manufactured from quaternary alkylammonium derivatives of stearic acids.

A sonobuoy is a small, expendable sonar system used primarily by naval forces to detect underwater objects such as submarines. Deployed from aircraft or ships, it floats on the ocean surface while its sensors descend underwater to transmit acoustic data back to operators via radio signals. Sonobuoys are essential tools in anti-submarine warfare (ASW), enabling real-time tracking and surveillance of underwater threats. They come in various types, including passive (listening only) and active (sending and receiving sound pulses), and are designed for short-term use in tactical operations.
