By the end of this module, you’ll be able to:
- List four categories of disease agent sources
- Discover conditions when disease transmission is likely to occur
- Describe the means of disease transmission in a given situation
Biosecurity: Routes of Infection and Means of Transportation
In this module, you'll be able to :
- Identify five routes of infection
- Describe how diseases are transmitted in animals
Types of Flow Measurement
Learners study the most common ways to measure fluid flow for industrial processes including absolute quantity, percentage, volumetric flow rate, and mass flow. A brief quiz completes the activity.
Work and Power (Screencast)
By James Bourassa, John Rosz
Learners examine the formulas for calculating work in ft-lb units and power in ft-lb/min. units.
Ultrasonic Sensors (Screencast)
In this animated activity, learners examine the operation of an ultrasonic sensor and the procedure to perform zero and span adjustments. A brief quiz completes the object.
Effects of a Rheostat in a Series Circuit
In this animated object, learners examine how the way in which a rheostat is connected in series with other resistors causes current and voltage to change as the resistance is varied. A brief quiz completes the activity.
