Abstract:
<strong>Background:&nbsp;</strong>A-scan ultrasound biometry (A-scan biometry/ A-scan)is mainly used to determine the axial length of the eye with the help of an ultrasound device. Axial length of eye is an important parameter to calculate Intra-ocular lens (IOL) power prior to cataract surgery. Different formulae to calculate the IOL power need axial length value along with keratometry value (calculated using a keratometer). Sometimes, the corneal compression caused during the A-scan measurement gives wrong values of the axial length. The objective of the present study was to compare accuracy

Abstract This study aims to explore the non-destructive detection method for such defects as debonding and delamination in carbon fiber/Ti alloy composite gun barrels during the preparation process. In this paper, the preparation method of composite barrel defective specimens is first introduced.

The results show that water immersion ultrasonic testing can identify the defects between the carbon fiber/Ti alloy layers, but CT scan fails to identify them. Therefore, immersion ultra

Abstract:
Deindividuation is among the classic phenomena researched by the early pioneers of social psychology. Building on the theorizing of LeBon (1895/1985), deindividuation provided an explanation for aggression in the crowd, a concern as relevant today as it was in the previous two centuries. The theory predicts that behavior becomes more antinormative and aggressive under conditions of anonymity, associated with group immersion, and that this occurs because of reduced self-awareness and deregulated behavior. However, close scrutiny of the deindividuation literature provides scant evidence for the

AbstractA-scan echography is used to measure the eye’s axial length. During A-scan biometry, the ultrasound beam must stay perpendicular to the anterior and posterior corneal surfaces, the anterior and posterior lens surfaces, and the retinal surface, forming an incidence angle of 90° with each of these surfaces. The immersion technique is preferred over the contact technique. Axial length measurements obtained with the contact technique were shorter than those obtained with the immersion technique by an average of 0.24 mm, mainly due to corneal compression.

AbstractThis is a complete analysis of the demographics of the biometry measurements of the human eye (using optical biometry) based on a very large series of over 80,000 eyes including all races and ages. It is an important update to the first such series of 7500 eyes by Hoffer (using immersion A-scan) more than 40 years ago. There are differences between the sexes (males have longer axial lengths and flatter corneas than females) and among racial groups (Asians have longer axial lengths). These data are important in regard to IOL power calculation and toric IOL implantation.
