Backscattered Electron

The backscattered electron coefficient η for transmission electron microscope specimens depends on both the atomic number Z and the thickness t. Hence for specimens of known atomic number, the thickness can be determined from backscattered electron coefficient measurements. This work describes a simple and convenient method of estimating the thickness and the corrected composition of areas of uncertain atomic number by combining x-ray microanalysis and backscattered electron intensity measurements.The method is best described in terms of the flow chart shown In Figure 1. Having selected a feature of interest, x-ray microanalysis data is recorded and used to estimate the composition. At this stage thickness corrections for absorption and fluorescence are not performed.

Serious Injuries

Introduction: Disk Battery Ingestion (DBI) is a cause of access to the emergency department (ED), especially in pediatric age. This problem, if not well managed, may lead to serious injuries, with several complications involving the gastrointestinal and respiratory tract. Objective: Aim of this review is to analyze the literature of the last 25 years to make a decisional flow-chart that may help the emergency physician. Methods: For this review 36 articles have been analyzed (8 articles and 28 case reports), from 1995 to 2019. Data considered from each study were: year of publication, type of study, population studied, type of battery, timing of ingestion, treatment, outcomes, complications. Results: A decisional flow-chart has been configured. X-ray should be performed as a first step in every stable patient, meanwhile CT scan should be performed in unstable patients. When the battery is still localized in the esophagus, endoscopy should be performed as soon as possible, meanwhile, when the battery is beyond the esophagus, it should be noted its diameter before taking a decision. Conclusion: The use of the flow-chart proposed may reduce the risk of consequences and severe injuries for the patients, helping the emergency physician in his decisional process.

Landslide Early Warning

Abstract. We define landslide Early Warning Systems and present practical guidelines to assist end-users with limited experience in the design of landslide Early Warning Systems (EWSs). In particular, two flow chart-based tools coming from the results of the SafeLand project (7th Framework Program) have been created to make them as simple and general as possible and in compliance with a variety of landslide types and settings at single slope scale. We point out that it is not possible to cover all the real landslide early warning situations that might occur, therefore it will be necessary for end-users to adapt the procedure to local peculiarities of the locations where the landslide EWS will be operated.

The Way

The theory and flow chart of inverse analysis arithmetic is based. The way of axile symmetry constringent and ring constringent test is introduced into optimization model and goal function , the goal is attained that inverse analysis of stainless steel is confirmed with grind and flowing vary coefficient, and that grind gene is confirmed with different plastic mock equipment. The result is proved that subdued stress of inverse analysis attained is treated as true subdued stress , the accuracy prediction of grind coefficient of ring constringent test on inverse analysis is obtained.
