Abstract An automated, qualitative and semi-quantitative micro-assay for the detection of plant lectins also known as phyto-agglutinins (glycoproteins; have exciting applications in medicines) is described an alternative to conventional assays. The method developed this work based on hemagglutination (HA) assay that can simultaneously detect presence concentration (titer) many 96 different samp...
We present a mixed finite element method for a model of the flow in a Hele-Shaw cell of 2-D fluid droplets surrounded by air driven by surface tension and actuated by an electric field. The application of interest regards a micro-fluidic device called ElectroWetting on Dielectric (EWOD). Our analysis first focuses on the time-discrete (continuous in space) problem and is presented in a mixed va...
the present study reports an analysis of response articles in four different disciplines in the social sciences, i.e., linguistics, english for specific purposes (esp), accounting, and psychology. the study has three phases: micro analysis, macro analysis, and e-mail interview. the results of the micro analysis indicate that a three-level linguistic pattern is used by the writers in order to cr...
the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...
. ترکیبات سنتزشده با استفاده از تکنیـک های طیف سنجـیir ، 13c nmr، 1h،31p ، 119snو بلورنگاری با پرتو x مورد شناسایی قرار گرفتند. محاسبات nbo با روش dft(b3lyp) با استفاده از 6-31+g* basis set انجام شد. در نهایت اثر ضدمیکروبی برخی از ترکیبات سنتز شده علیه 2 نوع باکتری گرم مثبت استافیلوکوکوس اورئوس و باسیلوس سابتیلوس و 2 نوع باکتری گرم منفی اشریشیاکولی (ا.کولی) و هلیکوباکترپیلوری با استفاده از روش ...
Polyamide-66(PA66)/CaCO3 micro- and nano-composites were prepared using a polymer solution method at filler loading of 0, 1, 2 and 3 weight percent. Nano-size of CaCO3 was synthesized by micro-emulsion technique. The material was characterized by XRD, SEM, FTIR and UV-VIS techniques. XRD results of composites suggested that CaCO3 particles are found in the amorphous phase of the semi-crystallin...
