Clasp retainers made of metal alloys may be esthetically unappealing or cause allergic reactions.To investigate alternative materials, we used the nonfiller polyetheretherketone (PEEK) to fabricate the clasp retainer of a removable partial denture for the mandibular bilateral distal free-end Camera Cleaning Kit abutment of an 84-year-old female.Two

In 3D terrain analysis, topographical characteristics, such as mountains or valleys, and geo-spatial data characteristics, such as specific weather conditions or objects of interest, are important features.Visual representations of these features are essential in many application fields, e.g., aviation, meteorology, or geo-science.However, creating

The air-cooled motor controller has been widely used in electric aircraft due to its simple heat dissipation structure and maintenance-free T-Shirt features.Being the main heating component of the electric propulsion system of electric aircraft, the weight and the volume of the air-cooled motor controller need to be strictly controlled.Due to the s
