Accuracy in x-ray reflectivity analysis
The influence of Poisson noise on the accuracy of x-ray reflectivity analysis is studied with an aluminium oxide (AlO) layer on silicon. A null hypothesis which argues that other than the exact solution gives the best fitness is examined with a statistical p-value test using a significance level of α = 0.01. Simulations are performed for a fit instead of a measurement since the exact error caus...
متن کاملPatient effective dose evaluation for chest X-ray examination in three digital radiography centers
Background: The radiation doses resulting from diagnostic X-ray examinations are routinely measured in terms of entrance surface dose (ESD) and effective dose (ED). In this study, for the purpose of radiation protection, the radiation doses received from Digital chest X-ray examination were evaluated in terms of ESD and ED. Material and Methods: The ED was calculated by using the MCNP ...
متن کاملX-ray cluster temperature profiles
Context. A study of the structural and scaling properties of the temperature distribution of the hot, X-ray emitting intra-cluster medium of galaxy clusters, and its dependence on dynamical state, can give insights into the physical processes governing the formation and evolution of structure. Aims. Accurate temperature measurements are a pre-requisite for a precise knowledge of the thermodynam...
متن کاملCrystallization and preliminary X-ray analysis of leukemia inhibitory factor.
Leukemia inhibitory factor (LIF) is a polyfunctional molecule with significant and diverse biological activities. LIF is a glycoprotein secreted by a number of different cell types in vitro. It is induced in fibroblasts, lymphocytes, monocytes and astrocytes by various inducers such as serum, TNF, interleukin-IP and EGF. Due to extensive and variable glycosylation the molecular weight can range...
متن کاملTemperature Experiments for Improved Accuracy in the Calculation of Polyamide-11crystallinity by X-ray Diffraction
The calculation of the crystalline index (CI) of polymeric materials by X-ray diffraction (XRD) may be rendered difficult by the number of overlapping crystalline phases and amorphous halos that contribute to the diffraction pattern. Rilsan Polyamide-11 (PA-11), produced by Arkema Inc., is a semi-crystalline polymer with an eleven-carbon repeat unit belonging to the general class of Nylon polym...
