Rapid antigen and antibody, serological tests, and RT ‑ PCR-based molecular methods are widely used for the detection of microorganisms worldwide. Objectives: This study aimed by Isothermal nucleic acid amplification techniques to detect the covid-19. Methods: In this study, 200 samples of nasopharynx and oropharynx were collected from Jamaran Heart Hospital in Tehran. Covid -19 was exami...

The manipulation of sound properties such as timing, amplitude, timbre, and pitch by different performers and styles is an important fact not to be missed when approaching instrumental sound synthesis. Expressive music performance studies the manipulation of such sound properties in an attempt to understand expression, so that it can be applied to sound synthesis for obtaining expressive instru...

This article explores the applicability of numerical homogenization techniques for analyzing transport properties in real foam samples mostly open-cell, to understand long-wavelength acoustics of rigid-frame air-saturated porous media, on the basis of microstructural parameters. Experimental characterization of porosity and permeability of real foam samples are used to provide the scaling of a ...

background and objectives: a new real- time pcr protocol for the detection of trichomonas vaginalis in pooled urine samples has been optimized and validated. materials and methods: the amplification protocol, targeting a 2kb repeated gene in the t. vaginalis genome, was optimized by varying pcr parameters. as a reference method, a real-time pcr protocol targeting the beta-tubulin gene (y. versl...

The analysis of food components is of high importance due to food safety and security. Here the electrochemical detection of caffeine was performed on different chemically modified graphene (CMG) surfaces carrying diverse amount of defects and oxygen functionalities. The analytical performances of graphite oxide (GPO), graphene oxide (GO), and electrochemically reduced graphene oxide (ERGO) wer...
