Weather surveillance radars observe clear-air radar echoes (CAE); aerial biota and irregularities in atmospheric refractive index caused the echoes. Using weak returns of atmospheric CAE, the radars have been applied to wind findings in a short radar range in a fair weather, in particular S-band radars. Long wavelength radars perform good to observe air motion, because a detectable turbulent sc...

This article presents the development of a “small contraction” sensor fabricated using 3D printing and intended for practical works biology; with aim to replace traditionally used system. is then integrated into Computer Assisted Experiment (CAE) environment. CAE teaching technology that allows students carry out acquisition processing their data on computer (saving, adding comments, amplificat...

The purpose of this research was to analyze EFL writing tasks in the most popular ESOL (English for Speakers of Other Languages) exam preparation courses in Iran: IELTS, TOEFL, FCE and CAE. Having collected the criteria of writing task appropriateness in light of the process-oriented approach to writing instruction, 114 learner participants were asked to rate EFL writing tasks based on a checkl...

Background: Coronary artery ectasia (CAE) is dilatation of an arterial segment to a diameter at least 1.5 times that of the adjacent normal coronary artery. The incidence of coronary artery ectasia is distinct in different countries that can be found in 1.2% to 5% of angiographic examinations. Methods: This is a retrospective study that was conducted from September 2019 to February 2020 in Ker...

We read the article “Apelin Levels In Isolated Coronary Artery Ectasia” written by Bilik et al.1) The study aimed to determine the relationship between plasma apelin levels and isolated coronary artery ectasia. They concluded that patients with isolated coronary artery ectasia (CAE) have decreased plasma apelin levels compared with the control group. CAE is well known as an atherosclerotic proc...
