TOWARDS ULTRAFAST LASER MICROMACHINING OF X-RAY GRATINGS AND CREATION OF SUB-MICRON HOLE PATTERNS, COMPARISON OF RESULTS WITH BESSEL AND GAUSSIAN BEAMS

We compare micromachining results with Gaussian and Bessel beams using an UV picosecond laser system and demonstrate feasibility to produce tungsten gratings for x-ray interferometry medical imaging, and sub-micrometer size hole patterns.The advantages of Bessel Ointment beams compared to Gaussian beams, are demonstrated for micromachining of recta

BACKGROUND:There is still no reliable biomarker for the diagnosis of pancreatic adenocarcinoma.Carbohydrate antigen 19-9 (CA 19-9) is a tumor marker only recommended for pancreatic adenocarcinoma follow-up.One of the clinical problems lies in distinguishing between this cancer and other benign pancreatic diseases such as chronic pancreatitis.In thi

This service program is motivated by the lack of confidence in communicating retarded students in SLB C Autis Negeri Tuban.The lack of confidence in communication is caused by the lack of mastery and Ointment understanding of vocabulary.Therefore, by using a semiotic integrated learning design with pop-up book media it is hoped that it will increas
