Small-angle scattering (SAS) technique is applied to study the nano and microstructural properties of spatial patterns generated from chaos game representation (CGR). Using a simplified version of Debye formula, we calculate and analyze in momentum space, the monodisperse scattering structure factor from a system of randomly oriented and non-interacting 2D Sierpinski gaskets (SG). We show that ...

We present a previously unreported series of five cases of acute angle closure glaucoma associated with watching the Australia soap opera "Neighbours". Two cases were bilateral and associated with watching two episodes of "Neighbours" on the same day. The pathogenesis, and possible role of watching soap operas in the causation of primary angle closure glaucoma is discussed.

For orthodontic diagnosis and treatment planning there are various ways to assess the jaw discrepencies. Using parameters such as ANB, Wit’s appraisal, Beta, Yen, W angles, with some limitations. To overcome these, MKG angle Tau were proposed.
 Aim objective: The present study assesses predictability of its correlation previous parameter. Materials methods: A total 105 lateral cephalograms...

Objective(s) The objective of this study was to document and explain bilateral differences in the Q angle. Materials and Methods Two hundred limbs of healthy adult Indian volunteers were studied. The Q angle was measured using a goniometric method with the subjects supine, quadriceps relaxed and lower limbs in neutral rotation. The relative lateral placement of the tibial tuberosity with res...

  Background: Abnormal angulation of the lunate can be an indication of intercarpal pathology. On magnetic resonance images (MRIs) the lunate often looks dorsally angulated, even in healthy wrists. The tilt on individual slices can also be different and might be misinterpreted as pathological, contributing to inaccurate diagnoses and unnecessary surgery. The primary aim of this study was to det...

in this work, laser bending of perforated sheets has been investigated numerically. laser bending of perforated sheets is more complicated than non-perforated sheets due to their complex geometries. in this paper, laser bending of perforated sheets is studied numerically in the form of thermo-mechanical analysis with abaqus/implicit code. for this purpose, the effects of process and sheet param...

wettability alteration is an important method for increasing oil recovery from oil-wet carbonatereservoirs. chemical agents like surfactants are known as wettability modifiers in carbonate systems.oil can be recovered from initially oil-wet carbonate reservoirs by wettability alteration from oil-wetto water-wet condition with adding dilute surfactant and electrolyte solutions. this paper invest...

in this paper, a novel approach for ranking fuzzy numbers based on the angle measure is introduced. several left and right spreads at each chosen levels of fuzzy numbers is used to determine center of mass points(cmps) and then, the angels between the cmps and the horizontal axis is calculated. the total angle is determined by averaging the computed angles and finally, the novel method is compa...

abstract background: coherent scattering leads to diffraction effects and especially constructive interferences. theseinterferences carry some information about the molecular structure of the tissue. as breast cancer isthe most widespread cancer in women, this project evaluated the application of small anglex-ray scattering (saxs) for differentiation between normal and cancerous breast tissues....

background: glaucomatous neuropathy is a type of cell death due to apoptosis. the p53 gene is one of the regulatory genes of apoptosis. recently, the association between the p53 gene encoding for proline at codon 72 and primary open-angle glaucoma (poag) has been studied in some ethnic groups. this study is the first association analysis of poag and p53 codon 72 polymorphism in iranian patients...
