The problem of recycling and rational use of leather production waste, especially in recent years, has become relevant all over the world. This is explained by the fact that in the process of producing natural leather, a large amount (30 - 50% of the mass of raw materials) of waste is formed.
FAIR engine replaces the air compression section of a Wankel rotary engine with a secondary combustion chamber; it executes two combustion cycles per shaft revolution. FAIR engine injects Oxygen Enriched Compressed Air (OECA) to accelerate the chemical reaction for thorough and clean combustion, it reduces NOX, HC, CO, etc. emissions.
The Rigid deployable shelter is comprised of 12 wedge-shaped segments that nest concentrically into one another and rotate outward around a central connected shaft in a degree-locked manner to form a shelter. Rapid deployment of the Shelter is facilitated by rotating inner segments around the central shaft.
Purpose of the headwear:
The collapsible protective headwear is comprised of helmet, earmuffs, eyewear, and facemask components designed to provide protection from head impacts, loud noises, and shield the eyes, nose and mouth from particulates when deployed.
There is a maternal morbidity crisis in the U.S. We need to do better. As a seasoned Labor and Delivery Nurse for 20 years I identified a way to positively impact this sobering statistic.
The following is not in the AI madness stream covering the whole world. It belongs to the traditional, conservative scientific research process related to quantum computing.
I am working on identifying technologies that can power military combat platforms in austere environments. With NATO announcing that it will be net zero emissions by 2050, there is a scramble to find technologies that can replace fossil fuels for operational platforms. There are currently no mature technologies that can meet operational requirements. This includes batteries,

Although vibration has been used in the past to minimize weld distortion, results have been inconsistent. Plus, if the vibration is produced with electric power, it poses a risk: loss of welding ground could result in the welding "signal" to be sent thru the vibrator's ground line, damaging it and the power cord and source, perhaps starting a fire.
In many developing cities, intersections are managed by outdated or manually operated signal systems that lack real-time adaptation, data integration, and remote monitoring capabilities. This leads to chronic congestion, unsafe pedestrian conditions, longer travel times, and increased emissions. While advanced traffic signal controllers exist, they are typically expensive, proprietary,
