This video, published by Erie Community College, features an experiment that involves placing a marshmallow in the vacuum chamber of a Rough Vacuum System Trainer (RVET) then reducing the pressure. Elena Brewer, physics professor at Erie Community College, provides step-by-step instructions for...

This video, published by Erie Community College (ECC), focuses on an experiment that involves spraying shaving cream in a beaker and placing it in the the vacuum chamber of a Rough Vacuum System Trainer (RVET) and then reducing the pressure. Elena Brewer, physics professor at ECC, provides...

In this video, published by Erie Community Colege, learners are guided step-by-step through the processes of building a rough vacuum system. The presenter names each part and discusses its installation throughout the demonstration. The video corresponds with lessons in a student lab manual and...

This video, published by Erie Community College, features a Rough Vacuum System Trainer (RVET) undergoing the pump-down process with a paper tissue simulating a dry contaminant. The experiment lasts five minutes and includes a pressure gauge with the current atmospheric pressure, allowing learners...

This video, published by Erie Community College, features an experiment that involves a Rough Vacuum System Trainer (RVET) undergoing the pump-down process with a wet paper tissue simulating a wet contaminant. The experiment lasts five minutes and includes a pressure gauge with the current...

In this video, published by Erie Community College, Professor Elena Brewer from Erie Community College provides an introduction to activity nine of the student lab manual, where learners measure pressure and pump-down time to examine the effects of leaks in rough vacuum systems. Learners will...

In this video, published by Erie Community College, physics professor Elena Brewer conducts the pump-down process on a Rough Vacuum System Trainer (RVET) with a real leak source present. Throughout the pump-down process, learners will document how long it takes for the atmospheric pressure in the...

In this video, published by Erie Community College, Professor Elena Brewer from Erie Community College conducts the pump-down process on a Rough Vacuum System Trainer (RVET) with a virtual leak source present. Throughout the pump-down process, learners will document how long it takes for the...

This lecture from the iBioSeminars project is presented by Mary C. Berckerle from the Huntsman Cancer Institute at the University of Utah and covers a new frontier in cell biology; how cells respond to mechanical information. Cells and tissues are exposed to physical forces in vivo and excessive...

This lecture from the iBioSeminars project, presented by Nevan Krogan of the Department of Cellular and Molecular Pharmacology at UC-San Francisco, covers mass spectrometry and its application to molecular biology. Mass spectrometry is a powerful tool for elucidating the elemental composition of a...
