USS Cairo
USS Cairo /ˈkeɪroʊ/ was one of the first American ironclad warships built at the beginning of the U.S. Civil War. Cairo was the lead ship of the City-class gunboats and named for Cairo, Illinois. In June 1862, she captured the Confederate garrison of Fort Pillow on the Mississippi, enabling Union forces to occupy Memphis. As part of the Yazoo Pass Expedition, she was sunk on 12 December 1862, while clearing mines for the attack on Haines Bluff. Cairo was the first ship ever to be sunk by a mine remotely detonated by hand. The remains of Cairo can be viewed at Vicksburg National Military Park with a museum of its weapons and naval stores.

All-Solid-State Lithium–Oxygen Batteries
All-solid-state lithium–oxygen batteries (ASSLOBs) are emerging as a promising next-generation energy storage technology with potential energy densities up to ten times higher than those of current LIBs. ASSLOBs utilize non-flammable solid-state electrolytes (SSEs) and offer superior safety and mechanical stability. However, ASSLOBs face challenges, including high solid-state interface resistances and unstable lithium-metal anodes.

Tool and Die Maker
Tool and die makers are a class of machinists in the manufacturing industries who make jigs, fixtures, dies, molds, machine tools, cutting tools, gauges, and other tools used in manufacturing processes. Depending on which area of concentration a particular person works in, he or she may be called by variations on the name, including tool maker (toolmaker), die maker (diemaker), mold maker (moldmaker) or tool jig and die-maker, etc. Tool and die makers work primarily in toolroom environments—sometimes literally in one room but more often in an environment with flexible, semipermeable boundaries from production work. They are skilled artisans (craftspeople) who typically learn their trade through a combination of academic coursework and hands-on instruction, with a substantial period of on-the-job training that is functionally an apprenticeship (although usually not nominally today). Art and science (specifically, applied science) are thoroughly intermixed in their work, as they also are in engineering. Manufacturing engineers and tool and die makers often work in close consultation as part of a manufacturing engineering team. There is often turnover between the careers, as one person may end up working in both at different times of their life, depending on the turns of their particular educational and career path. There was no codified difference between them during the 19th century and earlier parts of the 20th century; it was only after World War II that engineering became a regulated profession exclusively defined by a university or college engineering degree.Both careers require some level of talent in both artistic/artisanal/creative areas and math-and-science areas.

High-Pressure Processing on Biopolymer-Based Films
Suitable packaging material in combination with high-pressure processing (HPP) can retain nutritional and organoleptic qualities besides extending the product’s shelf life of food products. However, the selection of appropriate packaging materials suitable for HPP is tremendously important because harsh environments like high pressure and high temperature during the processing can result in deviation in the visual and functional properties of the packaging materials. Traditionally, fossil-based plastic packaging is preferred for the HPP of food products, but these materials are of serious concern to the environment. Therefore, bio-based packaging systems are proposed to be a promising alternative to fossil-based plastic packaging. Some studies have scrutinized the impact of HPP on the functional properties of biopolymer-based packaging materials.

The Cold Spray Method
The cold, thermal spraying technology “Cold Spray” is a method of processing particles in a solid state. Research conducted through cold spray technology has seen a significant improvement in material properties; when processing the particles in a solid state, they adhere to the surface instead of eroding it. Cold spraying has proven to be an effective technique for improving material properties, as confirmed by its integration into different fields and industries, becoming competitive by being the only method for depositing particles below their melting point.

Internet Kill Switch
An Internet kill switch is a countermeasure concept of activating a single shut off mechanism for all Internet traffic. The concept behind having a kill switch is based on creating a single point of control (i.e. a switch) for a single authority to control or shut down the Internet in order to protect it or its users. In the United States, groups such as the American Civil Liberties Union have criticized proposals for implementing the idea so far.

Juice Jacking: Security Issues and USB Technology
For a reliable and convenient system, it is essential to build a secure system that will be protected from outer attacks and also serve the purpose of keeping the inner data safe from intruders. A juice jacking is a popular and spreading cyber-attack that allows intruders to get inside the system through the web and theive potential data from the system. For peripheral communications, Universal Serial Bus (USB) is the most commonly used standard in 5G generation computer systems. USB is not only used for communication, but also to charge gadgets. However, the transferal of data between devices using USB is prone to various security threats. It is necessary to maintain the confidentiality and sensitivity of data on the bus line to maintain integrity.

Sound Masking
Masking Sound is the addition of generated sound (commonly, though inaccurately, referred to as "white noise" or "pink noise") into an environment to mask unwanted sound. It relies on auditory masking. Masking sound is not an active noise control (noise cancellation technique). Masking sound reduces or eliminates perception of sound. The technology is promoted as a widespread application to an entire area to improve the acoustical satisfaction, by improving the acoustical privacy of the space. This improves one's ability to focus and their productivity. Masking sound is analogous to light. - Sound Power and Luminosity - Sound Intensity and Light intensity - They both have spectral characteristics.

Radiated Emissions from Printed Circuit Boards with MR
With the growth of the radioelectronic complexity and the demand for cutting edge devices, the need to protect them and increase their reliability is also rising. There are many methods to provide this. Modal reservation is one of the most effective, reliable, and least complicated methods used nowadays. Using this method in tracing and mounting of printed circuit boards can guarantee both electromagnetic compatibility (by using modal filtering) and reliability (by using the cold redundancy) of the final electronic device.
