In this animated object, learners examine the operation of a zener diode in the forward and reverse bias conditions. A quiz completes the activity.

In this animated activity, learners examine how to change the gain of an optical sensor to overcome environmental conditions and distance.

Learners examine the occurrence of overflow and underflow conditions in a programmable logic controller. It is recommended that users view the learning object “Signed Binary Numbers” in advance of this object.

Explore what sexual harassment is, the three conditions that constitute harassing behavior, and the four levels of sexual harassment.

Learners read a brief introduction to in-control and out-of-control conditions and view a series of distribution curves. This is a follow-up to the learning object titled "Quality Basics: Variation."

Learners combine Boyle's Law and Charles's Law to solve for the pressure, volume, and temperature of a gas sample under two sets of conditions.

Boyle's Law states that gas volume varies inversely with the pressure at constant temperature and is described by the equation PV = constant. An example of a sample of gas at two conditions of P and V is used to illustrate the law.

In this interactive object, learners review the four types of hypersensitivity and check their knowledge of alternative names, mediators, and various antigens and disease conditions.

Using the principle of Pascal's Law, the learner will interpret the gauge readings in a hydraulic system to determine when the system is operating properly under various load conditions and when there is a defect.

Learners use peripheral vascular assessment data to examine characteristics of these four conditions: peripheral arterial disease, deep vein thrombosis, chronic venous insufficiency, and acute arterial occlusion. A matching exercise completes the learning object.

Learners review normal conditions that are associated with aging. Changes are highlighted in the cardiovascular, musculoskeletal, respiratory, gastrointestinal, urinary, reproductive, endocrine, nervous, and sensory systems.

In this animated activity, learners view the flip-flop and read about its outputs, the information it stores, and its storage conditions. A quiz completes the lesson.

In this interactive object, learners examine problem areas related to patients with arthritic conditions. They also identify treatment precautions and design a treatment plan.

In this animated object, learners examine how gas volume varies directly with absolute temperature (K at constant pressure). An example of a sample of gas at two conditions of volume and temperature is used to illustrate the law.

Learners examine the circuitry in a DC variable speed drive that prevents the motor from running at 0 rpm or at maximum speed under certain conditions.

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

Students read and test themselves on the conditions that cause specific acid/base imbalances.
