Additives to immobilize Heavy Metals
This experimental work assessed the efficiency of different additives (MWCNTs, montmorillonite and Portland cement) to immobilize the heavy metals lead, cooper, nickel and zinc in a soil in conditions similar to a real case scenario (percolation tests).

Adjustable-Speed Drive
Adjustable speed drive (ASD), also known as variable-speed drive (VSD), describes equipment used to control the speed of machinery. Many industrial processes such as assembly lines must operate at different speeds for different products. Where process conditions demand adjustment of flow from a pump or fan, varying the speed of the drive may save energy compared with other techniques for flow control. Where speeds may be selected from several different pre-set ranges, usually the drive is said to be adjustable speed. If the output speed can be changed without steps over a range, the drive is usually referred to as variable speed. Adjustable and variable speed drives may be purely mechanical (termed variators), electromechanical, hydraulic, or electronic.

AI in the Field of Surfactants
Artificial intelligence (AI) is increasingly being used in the field of surfactants to improve the efficiency, effectiveness, and sustainability of surfactant production and applications. One of the main applications of AI in surfactants is in the design and development of new surfactant molecules. By using machine learning algorithms and computational modeling, researchers can predict the properties and behavior of new surfactants before they are synthesized, reducing the time and cost required for research and development. AI is also being used to optimize surfactant production processes, by analyzing large amounts of data generated during production and identifying areas for improvement. For example, AI can be used to optimize surfactant synthesis conditions, such as temperature and pressure, to improve yield and reduce waste. In addition, AI is being used to develop predictive models for surfactant performance in specific applications, such as in the production of emulsions, foams, and coatings. By understanding the relationship between surfactant properties and application performance, researchers can design more effective and sustainable surfactant formulations.

AI-Based and Big Data Analytics on Urban Planning
In order to enable a holistic approach to design and planning, there is a need to integrate those data sources and combine them with other more traditional methods of urban assessment. At the same time, there are still various concerns about big data analytics based on AI-related tools connected, for example, with the accessibility to and accuracy of big data, as well as the limitations of different types of AI-based tools which do not permit this kind of analytics to fully replace traditional urban planning analyses. In terms of technological change, the application of big data in design and planning may greatly support traditional planning methods and provide conditions for innovation; however, due to its limitations, it can only enrich but in no way replace traditional urban studies.

Air Source Heat Pumps
An air source heat pump (ASHP) is a system that transfers heat from outside to inside a building, or vice versa. Under the principles of vapor compression refrigeration, an ASHP uses a refrigerant system involving a compressor and a condenser to absorb heat at one place and release it at another. They can be used as a space heater or cooler, and are sometimes called "reverse-cycle air conditioners". In domestic heating use, an ASHP absorbs heat from outside air and releases it inside the building, as hot air, hot water-filled radiators, underfloor heating and/or domestic hot water supply. The same system can often do the reverse in summer, cooling the inside of the house. When correctly specified, an ASHP can offer a full central heating solution and domestic hot water up to 80 °C.

AK-630
The AK-630 is a Soviet and Russian fully automatic naval close-in weapon system based on a six-barreled 30 mm rotary cannon. In "630", "6" means 6 barrels and "30" means 30 mm. It is mounted in an enclosed automatic turret and directed by MR-123 radar and television detection and tracking. The system's primary purpose is defense against anti-ship missiles and other precision guided weapons. However it can also be employed against fixed or rotary wing aircraft, ships and other small craft, coastal targets, and floating mines. Once operational, this weapon system was rapidly adopted, with up to 8 units installed in every new Soviet warship (from mine-hunters to aircraft carriers), and hundreds produced in total.

Akai AX60
The AX60 is a polyphonic analogue keyboard synthesizer manufactured by Akai Professional in the mid-1980s. It was Akai's answer to the popular Roland Juno series synthesizers. The AX60 uses voltage-controlled analogue oscillators and filter circuitry based on the Curtis Electronics CEM 3394 integrated circuit.

Biography
Albert Kingsbury
Albert Kingsbury (23 December 1863 – 28 July 1943) was an United States engineer, inventor and entrepreneur. He was responsible for over fifty patents obtained between the years 1902 to 1930.[1] Kingsbury is most famous for his hydrodynamic thrust bearing which uses a thin film of oil to support weights of up to 220 tons. This bearing extended the service life of many types of machinery during
