چکیده
duate ts, the s and , leak tector ble to An overview of typical simple experiments, intended for didactic laboratory vacuum classes for undergra students majoring in Physics, Physics Engineering and Material Sciences, is presented. For all the experimen students perform actual measurements of characteristics of different vacuum components or material propertie compare the obtained results with the values tabulated in the literature: pumping speed measurements measurements, outgassing rate determinations and roughing line conductance estimation. The use of a He leak de allows the measurement of helium permeability constants for different materials and, with an RGA, students are a perform quantitative measurements of isotopic abundances for gases like argon and krypton. r 2005 Elsevier Ltd.

Birdcage volume coils and magnetic resonance imaging: a simple experiment for students
Background This article explains some simple experiments that can be used in undergraduate or graduate physics or biomedical engineering laboratory classes to learn how birdcage volume radiofrequency (RF) coils and magnetic resonance imaging (MRI) work. For a clear picture, and to do any quantitative MRI analysis, acquiring images with a high signal-to-noise ratio (SNR) is required. With a give...
متن کاملUsing Cultured Mammalian Neurons to Study Cellular Processes and Neurodegeneration: A Suite of Undergraduate Lab Exercises.
Cell culture is a powerful tool for exploring cellular function. Culturing primary neurons has revealed how neurons communicate in learning and memory (Kandel, 2006) and provided insights into the mechanisms of neurodegenerative diseases such as Parkinson's and Alzheimer's disease (Alberio et al., 2012; Trinchese, et al., 2004). Here we describe a series of four modular laboratory exercises to ...

متن کاملDustbot: Bringing a Vacuum-Cleaner Agent to Life
A simple vacuum-cleaner agent is introduced in Russell and Norvig’s artificial intelligence (AI) text [Russell and Norvig, 2003] to illustrate different agent types to beginning AI students. Underlying the different agent types are several simple actions that take place in a vacuum cleaner world consisting of a grid of squares, some of which contain dirt. The agent’s actions include turning lef...
متن کاملIT-Enhanced Laboratory Experience within a Modern Undergraduate Engineering Curriculum
The emergence of Information Technology (IT) is enabling engineering educators to constantly reconsider both the content and means of delivery of modern undergraduate curricula. Online learning environments are rapidly becoming viable options for providing students with a bridge from theoretical concepts to practical engineering applications. They can be made to represent repositories of integr...
