die less explosive forming of circular plates is one of the most useful methods in the industries especially chemical applications. manufacturing of large vessel's head, multilayer rings and some parts of heat exchangers are the example of applying this method. many theoretical and experimental researches about examining the explosive forming of simple and single layer plate have been done...

The work presents application of previously proposed approach for transverse profile forming high energy electron beams with plastic samples made using 3D printing technology. collimator PLA (polylactide) is designed and produced in a frame this work. results 6 MeV beam clinical linear accelerator Elekta Synergy presented. Obtained comparison data from XiO dosimetry planning system shows good a...

recently, incremental sheet metal forming (ismf) process as one of the new methods in rapid prototyping collection has been considered by researchers. this process is based on a defined path in cnc controller and applies a spherical-head tool that supplies the required pressure for sheet metal forming. despite affirmation of process ability in forming symmetric geometries, some of its aspects s...

background a review of the related medical journals indicates that there is no definite evidence-based option for managing large proximal ureteral stones, although many procedures such as transureteral lithotripsy (tul), shock wave lithotripsy (swl), percutaneous nephrolithotripsy, laparoscopic ureterolithotomy, and open ureterolithotomy are currently used to treat this urological problem. obje...

It is known that the high–energy quark–quark scattering amplitude can be described by the expectation value of two lightlike Wilson lines, running along the classical trajectories of the two colliding particles. Generalizing the results of a previous paper, we give here the general proof that the expectation value of two infinite Wilson lines, forming a certain hyperbolic angle in Minkowski spa...

Type II supernovae (SNe), probably the most important contributors to stellar feedback in galaxy formation, explode within the very dense star-forming clouds, where the injected energy is most easily radiated away. The efficiency of type II SNe in injecting energy into the interstellar medium (ISM) and in re-heating a fraction of the original star-forming cloud is estimated with the aid of a tw...
