Virtual Work01:20

Virtual Work

1.4K
The principle of virtual work states that if a body is in static and dynamic equilibrium, then the sum of all the virtual work done by all external forces and couple moments for any given virtual displacement must be zero.
In static equilibrium, a body can experience an imaginary or virtual movement, such as displacement or rotation. The virtual work done by a force is equal to the dot product of force and virtual displacement in the direction of the force. When it comes to virtually rotating a...

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

446
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...

Principle of Virtual Work: Problem Solving01:13

Principle of Virtual Work: Problem Solving

1.7K
The principle of virtual work is an essential concept in the field of mechanics and engineering. This is used to solve problems related to the equilibrium of a structure or system. It is based on the assumption that if a system is in equilibrium, the work done by all the forces during a virtual displacement is zero. This principle is applied by considering virtual displacements of the system and the corresponding work done by internal and external forces.
To apply the principle of virtual work,...

Imaging Biological Samples with Optical Microscopy

11.1K
Optical microscopy uses optic principles to provide detailed images of samples. Antonie van Leeuwenhoek designed the first compound optical microscope in the 17th century to visualize blood cells, bacteria, and yeast cells. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes with enhanced magnification and resolution.
In optical microscopy, the specimen to be viewed is placed on a glass slide and clipped on the stage...

Virtual Work for a System of Connected Rigid Bodies01:06

Virtual Work for a System of Connected Rigid Bodies

773
Virtual work is a powerful method used to solve problems involving several connected rigid bodies. When the system is in equilibrium, virtual work is zero. This allows the calculation of the resulting forces when a system undergoes a virtual displacement. When attempting to analyze such a system, first, use a free-body diagram, where an independent coordinate represents the configuration of the links, and mark its deflected position resulting from the positive virtual displacement.
Next,...

Area of Science:

  • Histology
  • Pathology
  • Medical Education

Background:

  • Virtual microscopy has largely replaced traditional optical microscopy and glass slides in teaching cell, tissue, and organ structures.
  • The creation of virtual microscopy resources requires expensive equipment (whole slide scanners, large storage) and quality glass slides, limiting access for many institutions, particularly in developing countries.

Purpose of the Study:

  • To address the inequitable access to virtual microscopy resources.
  • To establish a centralized, accessible platform for sharing virtual histology and pathology image files.

Main Methods:

  • Development of the Virtual Microscopy Database (VMD), a web-based image file-sharing platform.
  • VMD allows registered users from research and educational institutions to upload, view, and download virtual slide files.
  • The platform is currently free to use, supported by the American Association of Anatomists and MBF Bioscience Inc.

Main Results:

  • The VMD provides a large repository of virtual histology and pathology image files.
  • It facilitates easy access for researchers and educators globally.
  • User registration is restricted to faculty and staff of research and educational institutions for non-profit educational and research purposes.

Conclusions:

  • The Virtual Microscopy Database (VMD) effectively democratizes access to virtual microscopy resources.
  • It supports non-profit educational and research endeavors by providing a shared digital library of histology and pathology slides.
  • The VMD aims to overcome resource limitations faced by institutions worldwide, fostering broader adoption of virtual microscopy in science education.
