The device was tested by means of a 3-degree ramp at the lower end of which was a level surface that ended with a 1...
متن کاملطراحی و امکان سنجی ساخت fluorescence detection system برای دستگاهpcr
در این پروژه هدف طراحی و ساخت fluorescence detection systemجهت آشکارسازی مولکول های dna می باشد. در روش pcr، طی چندین چرخه دمایی، مولکول های dna کپی می شوند و سپس با استفاده از روش fluorescence detection، مولکول های بر انگیخته شده dna آشکارسازی می شوند. پس از آشکارسازی می توان به کپی و یا عدم کپی dnaها پی برد.می توان برای جداسازی مولکول های dna بر اساس طولشان، از روش gel electrophoresis استفاده...
Remote control system of disaster response robot with passive sub-crawlers considering falling down avoidance
