Doppler sonographic criteria for assessing peripheral lymph nodes ! Introduction B-mode criteria provide the foundation for the sonographic identification of peripheral lymph nodes as normal or pathological and for differential diagnosis. “Sonography of Peripheral Lymph Nodes Part 1: Normal Findings and B-Image Criteria” therefore provides a comprehensive description of the sonographic appearan...
in the present work, a simple and sensitive method was developed for determination of morphine and heroin using gold nanoparticles as resonance rayleigh scattering (rrs) and colorimetric technique’s probe. synthesized gold nanoparticles by sodium citrate reduction method have a negative charge layer on their surfaces because of self-assembled citrate anions on their surface. binding of morphin...
In the developed countries, many organizations are regarded a...
The detailed performance comparison of four orthogonal transforms for grayscale image colorization using Thepade’s Transform Error Vector Rotation(TTEVR) algorithm is done here with five different color pallet sizes. The Thepade’s transform error vector rotation algorithms use binary numbers represented by four error vector sequences (Haar, Cosine, Slant & Hartley). The proposed technique uses ...
although there are studies on pragmatic assessment, to date, literature has been almost silent about native and non-native english raters’ criteria for the assessment of efl learners’ pragmatic performance. focusing on this topic, this study pursued four purposes. the first one was to find criteria for rating the speech acts of apology and refusal in l2 by native and non-native english teachers...
Abstract Background: Occupational exposure to styrene can lead to various psychological and somatic complaints including color vision disorder that can occur even in low concentrations. Color vision disease is an early clue for effect of styrene on human, which can be used as an appropriate screening method in workers exposed to styrene. Materials and Methods: Working in waxy foundry is a job...
Background and Aim: A good work environment is a place where one can feel relaxed and focused. In the field of environmental psychology, color is one of the environmental factors that greatly influence human perception and behavior. The purpose of this systematic review study was to investigate the effect of color on work environment. Methods: This article is a systematic review study. Full-te...
We propose a perceptually based system for pattern retrieval and matching. The central idea is that similarity judgment has to be modeled along perceptual dimensions. Hence, we detect basic visual categories that people use in their judgment of similarity, and design a computational model that accepts patterns as input and, depending on the query, produces a set of choices that follow human beh...
بررسی فرایند الکتروفنتون به منظور تصفیه ی پساب شرکت پتروشیمی شازند و بهینه سازی عوامل موثر بر فرایند
هدف از این تحقیق بررسی کارایی فرایند الکتروفنتون و بهینه سازی پارامترهای موثر بر فرایند به کمک طراحی آماری به منظور تصفیه پساب شرکت پتروشیمی شازند میباشد.در این تحقیق تاثیر پارامترهای : زمان واکنش ، چگالی جریان، ph پساب ، نسبت (?ml h?_2 o_2)/( lit pw) و نسبت مولی (mol h_2 o_2)/(mol fe^(2+) ) بر حذف cod و color از پساب پتروشیمی تحت فرایند الکتروفنتون( با الکترود های آهن و آلومینیوم به طور جداگان...
