Machining of advanced ceramics in the green state aims to achieve complex geometry with near-net-shape dimensions minimizing machining steps after sintering, good surface finish, economic efficiency and flexibility, and ...

The advanced ceramic machining in green and pre-sintered states aims to minimize the machining step after sintering, in order to reduce the high cost of the process. Such methods provide a considerable advantage in the ...

The instantaneous frequency (IF) image is proposed in this work. It is obtained by the differentiation of the instantaneous phase (IP) image, which in turn is calculated by replacing the amplitude information with the IP ...

The pitaya, a cactácea that produces exotic fruit, has been increasingly consumed, and with this there is the generation of the residues of the fruit, mainly its bark. The use of these wastes can minimize environmental ...

Three new and novel hybrids of coumarin pyridines with a donor π acceptor system were synthesized in a 5-step series, without metal catalysts or special experimental conditions. These compounds were characterized by melting ...

Las bebidas de frutas ricas en antocianinas han sido de especial interés como productos funcionales principalmente en razón de su actividad antioxidante. Este tipo de bebidas pueden convertirse en alimentos con potencial ...

Due to the qualities that snakes have to perform locomotion on any surface with great ease and without suffering severe wear, the skin of this species was evaluated as the organ responsible of these characteristics in order ...
