We consider a nonminimally coupled curvature-matter gravity theory at the Solar System scale. Both fifth force of Yukawa type and further non-Newtonian extra that arises from nonminimal coupling are present in solar interior atmosphere up to interplanetary space. The depends on spatial gradient space-time curvature R. conditions under which effects such forces can be screened by chameleon mecha...

The purpose of the study was to investigate the correlation between Corneal Visualization Scheimpflug Technology (Corvis ST tonometry: CST) parameters and various other ocular parameters, including intraocular pressure (IOP) with Goldmann applanation tonometry. IOP with Goldmann applanation tonometry (IOP-G), central corneal thickness (CCT), axial length (AL), corneal curvature, and CST paramet...

Although, most of the abnormal structures of human brain do not alter the shape of outer envelope of brain (surface), some abnormalities can deform the surface extensively. However, this may be a major problem in a surface-based registration technique, since two nearly identical surfaces are required for surface fitting process. A type of verification known as the circularity check for th...

Objective: To survey the different aspects of penile morphology among a sample of Egyptian males (normal, congenital curvature, etc.) and their relation to erectile dysfunction. Patients and Methods: A sample of 110 male subjects (age ranges from 20–36 years) was selected from our private centre to participate in our study. Although nearly half of them (54 subjects, 49%) had congenital penile a...

BACKGROUND AND PURPOSE Although the relevance of understanding spinal kinematics during functional activities in patients with complex spinal deformities is undisputed among researchers and clinicians, evidence using skin marker-based motion capture systems is still limited to a handful of studies, mostly conducted on healthy subjects and using non-validated marker configurations. The current s...

The shape measurement of goaf is an important job in mine project. With the rapid development of the measuring equipment, 3D laser scanner, which makes the efficiency of traditional work being improved, is widely used in goaf. The final result of 3D laser scan is a huge collection of points. Although different measuring intervals will lead different point cloud density, it also needs a large st...

Introduction: The aim of this study was to compare digital and conventional radiography in determining the working length of dilacerated canals. Methods: Thirty nine human extracted single-rooted teeth with root curvature more than 35 degrees were included in this study. After access preparation, a file was inserted into the canal and advanced until the file tip was visualized at the foramen. W...
