Multilayer x-ray mirror calibration by an energy dispersive method using an x-ray tube and a si(li) detector: absolute reflectivity, energy band pass, and overlapping order determination.

Journal of X-ray science and technology

Dhez P, Duval H, Malaurent JC.
PMID: 21307559
J Xray Sci Technol. 1992 Jan 01;3(3):176-93. doi: 10.3233/XST-1992-3303.

We describe under which conditions the x-ray energy dispersive method permits absolute reflectivity, energy band pass, and overlapping order determination on artificial multilayers. For such measurements a Si (Li) detector and a simple x-ray tube are used. Examples of...

Sonic band gaps in PCF preforms: enhancing the interaction of sound and light.

PMID: 19471368
Opt Express. 2003 Oct 06;11(20):2555-60. doi: 10.1364/oe.11.002555.

We study the localisation and control of high frequency sound in a dual-core square-lattice photonic crystal fibre preform. The coupled states of two neighboring acoustic resonances are probed using an interferometric set up, and experimental evidence is obtained for...

Limited information exists regarding BRCA1 and BRCA2 genetic testing and genetic diversity in BRCA1 and BRCA2 in sub-Saharan African populations. We report a novel mutation that consists of a deletion of 2 bp (c.1949_1950delTA) in the exon 11 of...

Precipitating factors leading to decompensation of chronic heart failure in the elderly patient in South-American community hospital.

Journal of geriatric cardiology : JGC

Diaz A, Ciocchini C, Esperatti M, Becerra A, Mainardi S, Farah A.

J Geriatr Cardiol. 2011 Mar;8(1):12-4. doi: 10.3724/SP.J.1263.2011.00012.

BACKGROUND: Exacerbations of heart failure appear frequently associated with precipitating factors not directly related to the evolution of cardiac disease. There still a paucity of data on the proportional distribution of precipitating factors specifically in elderly patients. The aim...

Elucidation of the structure of organic solutions in solvent extraction by combining molecular dynamics and X-ray scattering.

Angewandte Chemie (International ed. in English)
