The x-ray emission with the single crystal of lithium niobate (LiNbO3) or lithium tantalite (LiTaO3) by thermal changes in a vacuum system is closely concerned with the electronic state of each crystal. Therefore, lithium Kedge x-ray absorption near edge structures (XANES) spectra of these materials were measured in the region from 50 eV to 90 eV by means of total electron yield method (T.E.Y.)...

Microbial electrolysis cells (MECs) provide a high-yield method for producing hydrogen from renewable biomass. One challenge for commercialization of the technology is a lowcost and highly efficient cathode. Stainless steel (SS) is very inexpensive, and cathodes made of this material with high specific surface areas can achieve performance similar to carbon cathodes containing a platinum cataly...

The Oxford Achieving Resilience during COVID-19 (ARC) study collected data from adolescents (aged 13–18), and parents of adolescents, March 2020 to August 2021. Following a baseline survey (1274 completed baseline), participants were invited 11 follow-up weekly surveys then 9 monthly surveys, an optional cognitive task. Each included questionnaires on mental health, resilience wellbeing, relate...

The aim of this study is to investigate the gamma ray radiation absorption properties bismuth oxide (Bi2O3), and determine effect lead (PbO) additive in shielding Bi2O3. For reason, parameters such as mass attenuation coefficient (MAC), linear (LAC), half value layer (HVL), tenth (TVL) mean free path (mfp) were calculated theoretically for Bi2O3, PbO, 50% Bi2O3-50%PbO. all results obtained by u...

India is largest producer, consumer importer pulses in world. Pigeonpea an important pulse crop that plays role nutritional security people developing countries contributing protein intake. It a soil b...

Abstract Background Biological prostheses are increasingly been used in young patients to avoid anticoagulation. The Edwards Inspiris aortic bioprosthesis is extremely promising this population, since it has shown reduced calcification of the prosthetic leaflets preclinical and early clinical studies. Little data available, however, younger than 65. This study investigates hemodynamic performan...
