Modular single axis linear CNC sliding table is a fundamental component of many large electromechanical devices. Modular single axis linear CNC rolling sliding table usually includes guide rail seat, mobile slider, workpiece, ball screw nut pair, servo motor and other components. The screw slide table plays an irreplaceable role in industrial production, so it is of great signifi cance to design and study it. This article mainly provides a calculation method for the design of a linear sliding table, explaining the transmission scheme, rail and ...screw nut calculations, and introducing lubrication methods and pointing out precautions....Read More
Homo Sapiens is the most dangerous species ever to live on earth. Compared to other animals, its communications skills are inferior being dependant on speaking but can record language which helps it to make tools most of which are weapons. These skills could be diverted to peaceful purposes. This article describes the behaviour of the species and shows how it can save itself from self-infl icted extinction....Read More
This case study explores the eff ects of NeurOptimal neurofeedback therapy on a 27-year-old female patient with a history of cerebral vascular narrowing, resulting in physical and emotional challenges. Following neurosurgery at a young age, the patient exhibited signifi cant motor diffi culties and emotional distress, exacerbated by the COVID-19 pandemic. This study documents the administration of 12 NeurOptimal sessions, highlighting improvements in physical function, emotional regulation, and overall well-being. The fi ndings suggest that Neu...rOptimal neurofeedback may serve as an eff ective intervention for individuals with complex neurological histories....Read More
