The Yucatán Peninsula, a key region of the ancient Maya civilization, has long presented challenges in establishing absolute chronological frameworks for its cultural practices. While central regions Mesoamerica have been extensively studied, southern areas, including Yucatán, remain underexplored. Limekilns, integral to lime production pre-Hispanic society, are well suited archaeomagnetic studies due high temperatures (>700 °C) required their operation. This study analyzed 108 specimens...
Archaeological pottery X-radiography is mainly used for two applications: fabric characterization and identification of forming techniques. Both applications require imaging tempering materials other additives. With digital X-radiography, it easy to enhance the image compute characterize these materials. In this study, a combination ImageJ plug-ins such as “threshold”, “analyze particles”, “fit polynomial” were describe set composed archaeological sherds. It was found that different types...
The sputtering yield amplification (SYA) is a phenomenon based on doping target with atoms of higher atomic mass. This changes the depth and direction collision cascade in surface promoting ejection atoms. In this work, we present new way generating SYA without need expensive complex deposition systems. was accomplished by increasing working pressure adding small pieces W, as dopant element, racetrack Si target. physical phenomena necessary to promote SYA, for our experimental parameters,...
