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 flexcon reverse osmosis water storage tank 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 demons

Sublittoral rocky reef habitats host important ecological communities in UK waters, but their ecological condition is difficult to monitor.Monitoring methods based on seabed imagery data are prone to inconsistencies in both the identification and enumeration of species, which is a major hurdle in detecting meaningful ecological change.To overcome c

Abstract Background The paper aims to explore the elderly caregiving process in India from the perspective of both elderly as well as working women care providers, along with the challenges faced and the coping strategies adopted by them during the process.Methods In-depth interviews with 48 participants (care providers and care receivers) from 25

Contemporary philosophical and neurocognitive studies of the self have dissociated two distinct types of self-awareness: a 'narrative' self-awareness (NS) weaving together dea eyewear episodic memory, future planning and self-evaluation into a coherent self-narrative and identity, and a 'minimal' self-awareness (MS) focused on prese

Summary: Recurrent epidemics of drug-resistant Staphylococcus aureus illustrate the rapid lapse of antibiotic efficacy following clinical implementation.Over the last decade, community-associated methicillin-resistant S.aureus (MRSA) has emerged as a dominant cause of infections, and this problem is amplified by the hyper-virulent nature of these i
