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 beams compared to Gaussian beams, are demonstrated for micromachining of rectangular sh

The avirulence genes that have been identified in Magna-porthe grisea exhibit varying degrees of stability in infection assays.AVR1-MARA is considered one of the stable avirulence genes.In an effort to understand this stability, we analyzed the AVR1-MARA locus by physical read more mapping and chromosome walking.By walking toward AVR1-MARA from res

Bamban (Donax canniformis) is one of the biological resources that grow in the swampy areas and has been used by the community as a raw material in the form of woven handicrafts.Bamban bark that used as raw material woven texture is hard and the surface was very slippery so hard to make.This study was conducted to determine the nature of the charac
